                  REAL PROPERTY/PROJECT, BUILDINGS AND PREMISES

     1.1  REAL PROPERTY/PROJECT, BUILDINGS AND PREMISES.

          1.1.1 PREMISES. Upon and subject to the terms, covenants and
conditions hereinafter set forth in this Lease, Landlord hereby leases to Tenant
and Tenant hereby leases from Landlord the premises set forth in Section 6.2 of

and other improvements and facilities which Landlord is or will be constructing
as part of "Phase I" thereof, and (iii) may further be expanded, at Landlord's
sole and absolute discretion, to include additional office and other buildings,
parking structures, parking facilities, landscaping, driveways, plazas,

facilities. As used in this Lease, the terms "REAL PROPERTY" and "PROJECT",
shall mean, collectively: (A) the Existing Buildings; (B) the Buildings; (C) any
outside plaza areas, walkways, driveways, courtyards, public and private
streets, transportation facilitation areas and other improvements and facilities
now or hereafter constructed surrounding and/or servicing the Buildings and

hereafter servicing the Buildings, the Existing Buildings and any other
buildings which may be constructed within LNR Warner Center (collectively, the
"PARKING FACILITIES"), which are designated from time to time by Landlord as
common areas (or parking facilities, as the case may be) appurtenant to or
servicing the Buildings, the Existing Buildings and any such other buildings;
(D) any additional buildings, improvements, facilities, parking areas and
structures and common areas which Landlord (and/or any common area association
formed by Landlord or Landlord's assignee for LNR Warner Center) may add thereto
from time to time within or as part of LNR Warner Center; and (E) the land upon
which any of the foregoing are situated. The site plan depicting the current
configuration of the Real Property and proposed Phase I of LNR Warner Center
(which Phase I includes the Buildings, the Phase I Parking Structure, surface
parking areas, landscaping, driveways, plazas, walkways, courtyards, public and
private streets and common areas, and which may be revised by Landlord as
provided in the Tenant Work Letter) is set forth in EXHIBIT A-1 attached hereto.
Landlord has no obligation to expand or otherwise make any improvements within
the Project other than as set forth in Section 1.1.4 below, and other than
Landlord's obligations set forth in the Tenant Work Letter to construct (1) the
Base, Shell and Core of the Buildings and the other improvements within the
Phase I Project (as such term is defined in the Tenant Work Letter) as set forth
in the Phase I Project Plans (as defined in the

<PAGE>

Tenant Work Letter) as the same may be modified by Landlord pursuant to the
provisions of the Tenant Work Letter, and (2) the initial Tenant Improvements
for the Premises pursuant to the provisions of the Tenant Work Letter.

     1.1.3 TENANT'S AND LANDLORD'S RIGHTS. Tenant is hereby granted the right to
the nonexclusive use of the common corridors and hallways, stairwells,
elevators, restrooms and other public or common areas located within Building C,
and the non-exclusive use of the areas located on the Real Property designated
by Landlord from time to time as common areas for the Buildings; provided,
however, that (i) Tenant's use thereof shall be subject to (A) the provisions of
any covenants, conditions and restrictions regarding the use thereof now or
hereafter recorded against the Real Property (subject, however, to the
limitations contained in clauses (i) and (ii) in Section 5.1 below), and (B)
such reasonable, non-discriminatory rules, regulations and restrictions as
Landlord may make from time to time (which shall be provided in writing to
Tenant), and (ii) subject to Tenant's rights in Section 25.30 below, Tenant may
not go on the roof of Buildings without Landlord's prior consent and without
being accompanied by a representative of Landlord. Subject to the limitations in
Section 25.30 below, Landlord reserves the right from time to time to use any of
the common areas of the Real Property, and the roof, risers and conduits of the
Buildings for telecommunications and/or any other purposes, and to do any of the
following, as long as such acts (including any acts undertaken by Landlord as
the "Declarant" under any covenants, conditions and restrictions recorded
against the Real Property) are performed in accordance with all applicable Laws
(as defined in Article 22 below) and do not materially and adversely interfere
with Tenant's permitted use of or access to the Premises or materially increase
Tenant's obligations under this Lease: (1) make any changes, additions,
improvements, repairs and/or replacements in or to the Real Property or any
portion or elements thereof, including, without limitation, (x) changes in the
location, size, shape and number of driveways, entrances, loading and unloading
areas, ingress, egress, direction of traffic, landscaped areas, walkways, public
and private streets, plazas, courtyards, transportation facilitation areas and
common areas, and, subject to Article 24 below, parking spaces, parking

or deleting buildings thereon and therefrom; (2) close temporarily any of the
common areas while engaged in making repairs, improvements or alterations to the
Real Property; (3) form a common area association or associations under
covenants, conditions and restrictions to own, manage, operate, maintain, repair
and/or replace all or any portion of the landscaping, driveways, walkways,
parking areas, public and private streets, plazas, courtyards, transportation
facilitation areas and/or other common areas located outside of the Buildings,
and, subject to Section 4.2.5 below, include the common area assessments, fees
and taxes charged by the association(s) and the cost of maintaining, managing,
administering and operating the association(s), in Direct Expenses; and (4)
perform such other acts and make such other changes with respect to the Real
Property as Landlord may, in the exercise of good faith business judgment, deem
to be appropriate.

     1.1.4 FOOD SERVICE; CHILD CARE FACILITY. Subject to the applicable
conditional use permits, project approvals issued by the City of Los Angeles,
covenants and agreements with the City of Los Angeles and other entitlements for
the Project which permit Landlord to develop the Project, which may be amended
from time to time (collectively, the "ENTITLEMENTS"), and subject to all other
applicable Laws (as defined in Article 22 below), Landlord shall use
commercially reasonable efforts to substantially complete (punch-list items
excepted) construction of a facility in the Project from which a retail food
service business may be operated on or before the first (1st) anniversary of the
Lease Commencement Date. In addition, subject to the Entitlements and all other
applicable Laws, Landlord shall use commercially reasonable efforts to
substantially complete (punch-list items excepted) construction of a child care
facility in the Project as soon as reasonably possible following the
satisfaction or waiver of the conditions set forth in the immediately succeeding
sentence. Tenant hereby acknowledges that Landlord has advised Tenant that the
Entitlements for the Project described above restrict Landlord from commencing
construction of such child care facility until the following have been
completed: (i) the development and construction of Phase I of the Project; (ii)
if and when constructed by Landlord, at Landlord's option, the portion of the
Project which Landlord constructs as "Phase II"; and (iii) if and when performed
by Landlord, at Landlord's option, the grading of the portion of the Project
which Landlord constructs as "Phase III". Tenant agrees that in connection with
Landlord's financing, transfer or sale of all or any portion of the Real
Property, or for any other reason determined by Landlord, Landlord may, at any
time after execution of this Lease, remove this Section 1.1.4 (and Landlord's
obligations hereunder) from

                                      -2-
<PAGE>

this Lease and instead include the provisions of this Section 1.1.4 and
Landlord's obligations hereunder in a separate written agreement independent
from this Lease (which separate agreement shall, at Landlord's election, only
pertain to such portions of the Real Property owned by Landlord [which may be
less than the entire Real Property] and designated by Landlord to be the
property upon which Landlord may construct the restaurant and child care
facility). Tenant shall promptly execute such separate agreement, as well as an
amendment to this Lease deleting this Section 1.1.4 therefrom (and otherwise
modifying this Lease to delete any references to Section 1.1.4 and the
restaurant and child care facility), following Landlord's election and
submission of such documents to Tenant, provided that the form and substance of
such separate agreement and amendment to Lease are reasonably acceptable to
Tenant.

     1.2  RENTABLE AND USABLE SQUARE FEET. The rentable and usable square feet
of the Premises are approximately as set forth in Section 6.2 of the Summary.
For purposes hereof, the "usable square feet" of the Premises and the "rentable
square feet" of the Premises and the Buildings shall be calculated by Landlord
pursuant to the Standard Method for Measuring Floor Area in Office Buildings,
ANSI Z65.1-1996 (the "BOMA STANDARD"). The rentable square feet of the Buildings
is estimated to be 356,490 rentable square feet. The usable square feet of the
Premises and the rentable square feet of the Premises and the Buildings shall be
certified to Landlord and Tenant with reasonably particularized supporting
calculations by Landlord's planner/designer prior to the Lease Commencement
Date, and such certification shall be made in accordance with the provisions of
this Section 1.2 (the "CERTIFICATION"); provided, however, that in the event
that Tenant's architect disputes the number of usable or rentable square feet in
the Premises or the rentable square feet in the Buildings as set forth in the
Certification, written notice of such dispute shall be provided to Landlord
within thirty (30) days after Tenant's receipt of the Certification. If Tenant
fails to deliver to Landlord written notice of such dispute within such 30-day
period, Tenant shall be deemed to have approved the Certification. To resolve
any such dispute, Landlord's planner/designer, Tenant's architect, Tenant and
Landlord shall meet to attempt to reach agreement on the number of rentable and
usable square feet in the Premises and the number of rentable square feet in the
Buildings. If such parties cannot agree on such numbers, then the parties shall
promptly submit the dispute to binding arbitration under the auspices of
JAMS/ENDISPUTE (or any successor to such organization) in Los Angeles,
California, according to the then rules of commercial arbitration for such
organization but with reference to the BOMA Standard, and the arbitrators
resolving such dispute shall only have jurisdiction to determine the square
footage of the Premises and Buildings in dispute, and shall not have
jurisdiction to modify the terms of this Lease. During the period from the Lease
Commencement Date until any dispute regarding the square footage of the Premises
and Buildings is resolved, the rentable and usable square footage amounts set
forth in Section 6.2 of the Summary and this Section 1.2 shall be utilized for
all purposes under this Lease. In the event that following such dispute it is
mutually determined by the parties or pursuant to such arbitration that the
rentable and usable square footage amounts of the Premises and/or Buildings are
other than those set forth in Section 6.2 of the Summary and/or this Section
1.2, all amounts, percentages and figures appearing or referred to in this Lease
based upon such incorrect rentable and/or usable square footage amounts
(including, without limitation, the amount of the Base Rent, the Tenant
Improvement Allowance and Tenant's Building C Share, but specifically excluding
Tenant's Building B Share) shall be modified in accordance with such
determination. If such determination is made, it will be confirmed in writing by
Landlord to Tenant. At either party's discretion, the number of rentable and
usable square feet of any First Offer Space and/or FHS Expansion Space leased by
Tenant pursuant to Sections 1.5 and/or 1.6 of this Lease, and of the remainder
of any partial floor space following a reduction pursuant to Section 1.7 of this
Lease, if applicable, shall be subject to verification, and such verification
shall be made in accordance with the BOMA Standard and the provisions of this
Section 1.2; in the event that it is determined that the rentable and/or usable
square feet of any such space pursuant to the BOMA Standard shall be different
from the amounts thereof set forth in this Lease or as may be initially
determined by Landlord, Landlord shall modify all amounts, percentages and
figures with respect to such space appearing or referred to in this Lease to
conform to such corrected square footage amounts therefor (including, without
limitation, the amount of the Base Rent, Tenant's Share of Direct Expenses and
any tenant improvement allowances applicable to such space).

     1.3  CONDITION OF THE PREMISES; HAZARDOUS MATERIALS. Except as specifically
set forth in this Lease and in the Tenant Work Letter attached hereto as
EXHIBIT B, (i) Landlord shall not be obligated to provide or pay for any
improvement work or services related to the improvement of the Premises, the
Buildings, the Existing Buildings or the Real Property, and (ii) Landlord has

                                      -3-
<PAGE>

made no representation or warranty regarding the condition of the Premises, the
Buildings, the Existing Buildings or the Real Property. Notwithstanding the
foregoing, Landlord hereby represents and warrants to Tenant that, to Landlord's
actual knowledge without duty of investigation or inquiry, as of the date of
execution of this Lease, the individual parcels of land within Phase I of the
Real Property upon which the Buildings are to be constructed (as depicted on
EXHIBIT A-1) do not currently contain any Hazardous Materials (as defined below
in this Section 1.3) in violation of existing applicable Environmental Laws (as
defined below in this Section 1.3), except as described in the Environmental
Reports (as such term is defined below in this Section 1.3) copies of which have
been delivered by Landlord to Tenant; such representation and warranty pertains
only to the land within Phase I upon which the Buildings shall be constructed,
and not to the land upon which the Existing Buildings are constructed or any
other land on the Real Property, nor the Existing Buildings or any other
improvements now or hereafter located on the Real Property. Landlord further
covenants that Landlord shall observe and comply with all applicable
Environmental Laws in connection with Landlord's activities on the Real Property
(including, without limitation, Landlord's actions undertaken pursuant to
Sections 1.1.3 and 25.29 of this Lease), and in connection therewith, Landlord
shall not cause any Hazardous Materials to be introduced in, on or under the
Real Property by Landlord, its agents, employees or contractors in violation of
Environmental Laws in effect at the time of such introduction. Landlord shall
also use commercially reasonable efforts to cause the tenants of the Project
(other than Tenant) who have introduced any Hazardous Materials in, on or under
the Real Property in violation of Environmental Laws to clean-up and/or
remediate such Hazardous Materials, at no cost to Tenant, to the extent required
by applicable Environmental Laws. Landlord shall indemnify, defend, reimburse
and hold Tenant harmless from and against the cost of remediation of any
Hazardous Materials to the extent (i) existing on the Real Property as of the
date of execution of this Lease in violation of applicable Environmental Laws at
such time (including as a result of Landlord's utilization thereof in connection
with the original construction of the Phase I Project), and/or (ii) resulting
from Landlord's breach of its representations and/or covenants in this Section
1.3. Such indemnity shall survive the expiration or earlier termination of this
Lease. For purposes hereof, "costs of remediation" shall mean the costs
associated with the investigation, testing, monitoring, containment, removal,
remediation, cleanup and/or abatement of any release of any such Hazardous
Materials described in the immediately preceding sentence as necessary to comply
with any applicable Environmental Laws. As used in this Lease, the term
"HAZARDOUS MATERIALS" shall mean and include any substance that is or contains
petroleum, asbestos, polychlorinated biphenyls, lead, or any other substance,
material or waste which is now or is hereafter classified or considered to be
hazardous or toxic under any federal, state or local law, rule, regulation or
ordinance relating to pollution or the protection or regulation of human health,
natural resources or the environment (collectively, "ENVIRONMENTAL LAWS"). As
used in this Section 1.3, the term "ENVIRONMENTAL REPORTS" collectively refers
to the following reports prepared with respect to the Real Property: (A) that
certain letter dated June 8, 1998 from American Environmental Specialists, Co.
to Mr. Kevin Read at Lennar Partners; (B) that certain Bulk Asbestos Survey
dated August 22, 1997 prepared by McLaren/Hart; and (C) that certain Phase I
Environmental Assessment dated August 22, 1997 prepared by McLaren/Hart.

     1.4  INTENTIONALLY DELETED.

     1.5  RIGHT OF FIRST OFFER. Tenant shall have a right of first offer to
lease certain space in Building C as follows:

          1.5.1 RIGHT OF FIRST OFFER; FIRST OFFER SPACE. During the period of
time from and after the date of execution of this Lease until the end of the
initial Lease Term as may be extended for the First Option Term only ("FIRST
OFFER ELIGIBILITY PERIOD"), Tenant shall have a right of first offer to lease
the remaining space in Building C not leased by Tenant at the time Landlord
delivers the First Offer Notice, as such term is defined in Section 1.5.2 below
(including, without limitation, any Reduction Space [as such term is defined in
Section 1.7 below] provided that Landlord has entered into a Third Party Lease
[as such term is defined below in this Section 1.5.1] with a third party after
the time that Tenant returns possession of such Reduction Space to Landlord
pursuant to Tenant's reduction rights set forth in Section 1.7 below) (the
"FIRST OFFER SPACE"), when such space (or applicable portion thereof) becomes
available for lease as provided hereinbelow as reasonably determined by
Landlord. For purposes hereof, the applicable First Offer Space shall only
become available for lease to Tenant (i) after Landlord has entered into a lease
with a third party for such First Offer Space (a "THIRD PARTY

                                      -4-
<PAGE>

LEASE"), and (ii) following the expiration or earlier termination of such Third
Party Lease and after such third party has vacated such space.

               1.5.1.1 Notwithstanding the foregoing, with respect to that
certain space located on the first floor of Building C as depicted on EXHIBIT M
attached hereto containing approximately 14,847 rentable square feet (the "FIRST
FLOOR FIRST OFFER SPACE"), in addition to Tenant's right of first offer to lease
the First Floor First Offer Space after such space becomes available for lease
following Landlord's lease of such space to a third party with a Third Party
Lease as provided in Section 1.5.1 above, Tenant shall also have the one-time
right of first offer pursuant to this Section 1.5.1.1 to lease the First Floor
First Offer Space prior to the first time Landlord has entered into a Third
Party Lease with any third party therefor which is other than Aetna Life
Insurance Company or its affiliate or designee ("AETNA"), when such space
becomes available for lease as reasonably determined by Landlord as provided
hereinbelow. The First Floor First Offer Space shall become available for lease
pursuant to the immediately preceding sentence prior to the first time Landlord
intends to submit to a third party which is other than Aetna a bona fide
proposal or letter of intent to lease all or any portion of the First Floor
First Offer Space.

               1.5.1.2 Further, if Landlord determines, in its sole discretion,
to terminate lease negotiations with Aetna for that certain space (the "AETNA
FIRST OFFER SPACE") which consists of the second (2nd) floor of Building C and
the balance of the first floor of Building C which is other than the First Floor
First Offer Space described in Section 1.5.1.1 above, in addition to Tenant's
right of first offer to lease the Aetna Space after such space becomes available
for lease following Landlord's lease of such space to a third party with a Third
Party Lease as provided in Section 1.5.1 above, Tenant shall also have the
one-time right of first offer pursuant to this Section 1.5.1.2 to lease the
Aetna Space prior to the first time Landlord has entered into a Third Party
Lease with any third party therefor, when such space becomes available for lease
as reasonably determined by Landlord as provided hereinbelow. The Aetna Space
shall become available for lease pursuant to the immediately preceding sentence
prior to the first time Landlord intends to submit to a third party which is
other than Aetna a bona fide proposal or letter of intent to lease all or any
portion of the Aetna Space.

               1.5.1.3 Any First Floor First Offer Space or Aetna Space leased
by Tenant pursuant to Sections 1.5.1.1 or 1.5.1.2 above (but not pursuant to
Section 1.5.1 above) shall be collectively referred to herein as the "SPECIAL
FIRST OFFER SPACE".

               1.5.1.4 Tenant's right of first offer shall be on the terms and
conditions set forth in this Section 1.5 and, at Tenant's election, (A) shall be
for the entire amount of the First Offer Space which becomes available for lease
as determined by Landlord as provided herein, and not a portion thereof, or (B)
with respect to any First Offer Space which is other than the First Floor First
Offer Space, shall be for not less than contiguous full floor portions of such
First Offer Space starting with the highest floor contiguous to the remainder of
the Premises in Building C leased by Tenant as of the date Tenant delivers its
applicable Tenant's Election Notice (as defined below) exercising Tenant's right
of first offer for such space (for example, if the First Offer Notice indicates
that the available First Offer Space consists of Floors 1 and 2 of Building C
and as of the date of Tenant's Election Notice the portion of the Premises in
Building C that Tenant is leasing consists only of Floors 3, 4 and 5 of Building
C, then Tenant may elect pursuant to this clause (B) to lease either (x) all of
Floor 1, (y) all of Floor 2, or (z) all of Floors 1 and 2). In the event that
only a portion of the First Offer Space becomes available for lease (as
reasonably determined by Landlord), Tenant's right of first offer shall continue
as to the remainder of the First Offer Space, when such remainder becomes
available (as reasonably determined by Landlord) on the terms and conditions set
forth in this Section 1.5. Notwithstanding anything herein to the contrary,
Tenant's right of first offer set forth in this Section 1.5 shall be subject to
the rights of the third party tenant under a Third Party Lease to renew the
lease term of the Third Party Lease, but only if such renewal is consummated
pursuant to an express provision in such lease or any modification of any
express renewal provision that may be agreed upon by Landlord and such party (so
long as such modification does not provide for a longer renewal term than
originally provided in such express renewal provision).

          1.5.2 FIRST OFFER NOTICE; TERMS OF LEASE OF FIRST OFFER SPACE. During
the First Offer Eligibility Period, Landlord shall give Tenant written notice
(the "FIRST OFFER NOTICE") when the First Offer Space (or any portion thereof)
is expected to become or has become available for lease by Tenant during the
First Offer Eligibility Period (as such availability is

                                      -5-
<PAGE>

reasonably determined by Landlord) pursuant to the terms of Tenant's right of
first offer, as set forth in this Section 1.5. With respect to any First Offer
Space which is other than the Special First Offer Space leased by Tenant
pursuant to Sections 1.5.1.1 or 1.5.1.2 above, Landlord shall use its best
efforts to deliver the First Offer Notice at least six (6) months prior to the
date Landlord anticipates that the applicable First Offer Space will become
available for lease by Tenant; provided, however, that Landlord shall not be
liable to Tenant in the event that such notice is inaccurate as to the precise
availability date, so long as Landlord exercised good faith and reasonable
judgment in determining such anticipated delivery date identified in the First
Offer Notice. Landlord's First Offer Notice shall describe the First Offer Space
so offered to Tenant and the rentable and usable square footage thereof as
determined by Landlord pursuant to Section 1.3, and shall also set forth the
annual Base Rent for the First Offer Space (the "FIRST OFFER SPACE RENT") and
the other material terms upon which Landlord would lease the First Offer Space
to Tenant; provided, however, that:

               (i)  the lease term for the First Offer Space shall be
coterminous with the Lease Term for the original Premises (as may be extended
pursuant to the Extension Option Rider) unless, if by making the term of the
lease for the First Offer Space coterminous with the Lease Term for the original
Premises, the term of the lease for the First Offer Space would be less than
five (5) years, then the lease term for the First Offer Space shall be, at
Landlord's election, either five (5) years or such shorter period as Landlord
shall so specify in Landlord's First Offer Notice; however, if Landlord so
specifies a term which is shorter than five (5) years and Tenant objects thereto
concurrently with Tenant's delivery of Tenant's Election Notice (as such term is
defined in Section 1.5.3 below), the term of the lease for the First Offer Space
shall be coterminous with the Lease Term for the original Premises;

               (ii) except for any Special First Offer Space leased by Tenant
pursuant to Sections 1.5.1.1 or 1.5.1.2 above, subject to such tenant
improvement allowance to be provided to Tenant for such First Offer Space as
determined pursuant to the following provisions of this Section 1.5.2, Tenant
shall take such First Offer Space in its "as-is" condition as of the date of
delivery of such space, and the construction of improvements in such First Offer
Space shall be Tenant's sole responsibility, with any such construction to
comply with the terms of Article 8 of this Lease; and

               (iii) with respect to any Special First Offer Space leased by
Tenant pursuant to Sections 1.5.1.1 or 1.5.1.2 above, Landlord shall construct
the initial tenant improvements for such Special First Offer Space (and the
base, shell and core if not already constructed for such space) pursuant to a
tenant work letter substantially the same as the Tenant Work Letter attached to
this Lease as Exhibit B, except that: (A) the time deadlines for submittal and
approval of plans and specifications and other actions required to be performed
by Landlord and Tenant shall be revised with respect to the Special First Offer
Space pursuant to a schedule mutually approved by the parties and set forth in
the amendment to Lease described in Section 1.5.4 below (except that there shall
be no staged delivery or Delivery condition provisions with respect to any
portion of the Special First Offer Space); (B) Sections 5.4 and 5.5 of the
Tenant Work Letter shall not apply with respect to the Special First Offer
Space; (C) the tenant improvement allowance for the Special First Offer Space
shall be determined as part of the Fair Market Rental Rate for the Special First
Offer Space as provided in Section 1.5.2.2 below; and, unless otherwise mutually
agreed to by Landlord and Tenant, Tenant shall not be entitled to use any
portion of such tenant improvement allowance for any of Tenant's Property or
Moving/Personal Property Costs as provided in the Tenant Work Letter; (D) the
fixed fees and general conditions for the Contractor if Landlord selects Snyder
Langston as the Contractor currently set forth in the Tenant Work Letter, and
the provisions requiring Landlord to enter into a guaranteed maximum
construction contract with the Contractor shall not apply with respect to the
Special First Offer Space unless otherwise mutually approved by Landlord and
Tenant; and (E) the terms and conditions of the Tenant Work Letter attached to
this Lease which conflict with the terms and conditions of this Section
1.5.2(iii) shall not apply.

               1.5.2.1 LEASE OF FIRST OFFER SPACE DURING THE FIRST THREE YEARS
OF THE LEASE TERM. In the event that the First Offer Commencement Date for the
applicable First Offer Space leased by Tenant (which is other than the Special
First Offer Space leased by Tenant pursuant to Sections 1.5.1.1 or 1.5.1.2
above) occurs prior to the last day of the third (3rd) year of the initial Lease
Term, Tenant's lease of such First Offer Space (sometimes referred to herein as
the "PRE-THIRD YEAR OFFER SPACE") shall be upon the same terms and conditions of
this Lease as applicable to the original Premises, except that the Tenant Work
Letter attached hereto

                                      -6-
<PAGE>

as EXHIBIT B and the Tenant Improvement Allowance set forth therein shall not
apply with respect to such Pre-Third Year Offer Space, but the tenant
improvement allowance for the applicable Pre-Third Year Offer Space shall equal
the Fair Market Allowance (as such term is defined below) therefor.
Specifically, (i) the annual Base Rent payable for the Pre-Third Year Offer
Space shall be at the same base rental rate per rentable square foot as Tenant
is paying for the original Premises and shall be subject to increases at the
same time and at the same base rental rate per rentable square foot as the
annual Base Rent is increased for the original Premises; (ii) the Base Year used
for determining Tenant's obligation to pay Direct Expenses for the Pre-Third
Year Offer Space shall be the same as the Base Year used for determining
Tenant's obligation to pay Direct Expenses for the original Premises; (iii)
Tenant's Share shall be increased to take into account the rentable square feet
of the Pre-Third Year Offer Space; and (iv) Tenant shall be entitled to rent, at
no charge during the initial Lease Term, additional unreserved, undesignated
parking spaces in the Parking Facilities at the ratio of four (4) unreserved,
undesignated parking spaces for each 1,000 rentable square feet of the Pre-Third
Year Offer Space so leased by Tenant. In lieu of the Tenant Improvement
Allowance provided in the Tenant Work Letter, Landlord shall provide Tenant with
a tenant improvement allowance for such Pre-Third Year Offer Space equal to the
tenant improvement allowance provided to non-equity tenants, as of the
commencement of the lease term for such Pre-Third Year Offer Space, who are
leasing non-sublease, non-equity, unencumbered space on a full-service gross
basis comparable in size, location and quality to the Pre-Third Year Offer Space
for a comparable term, which comparable space is located in the Project and in
other first-class office buildings in Woodland Hills, California (collectively,
the "COMPARABLE BUILDINGS") (but in determining any such tenant improvement
allowance, the quality and quantity of tenant improvements in the Pre-Third Year
Offer Space shall be taken into account and the value thereof deducted from such
allowance to the extent the same can be used by a general office user), and
taking into consideration that Tenant's lease of such Pre-Third Year Offer Space
shall be subject to the Base Rent and Base Year specified in clauses (i) and
(ii), respectively, of the immediately preceding sentence (the "FAIR MARKET
ALLOWANCE"); provided, however, in no event shall the Fair Market Allowance
provided to Tenant be less than $10.00 per usable square foot of the Pre-Third
Year Offer Space.

               1.5.2.2 LEASE OF SPECIAL FIRST OFFER SPACE AND FIRST OFFER SPACE
AFTER THE FIRST THREE YEARS OF THE LEASE TERM. In the event that the First Offer
Commencement Date for the applicable First Offer Space leased by Tenant (which
is other than the Special First Offer Space leased by Tenant pursuant to
Sections 1.5.1.1 or 1.5.1.2 above) occurs after the last day of the third (3rd)
year of the initial Lease Term, the First Offer Space Rent payable for such
First Offer Space (sometimes referred to herein as the "POST-THIRD YEAR OFFER
SPACE") shall be equal to ninety-five percent (95%) of the "FAIR MARKET RENTAL
RATE" for such Post-Third Year Offer Space (as such term is defined in Section 2
of the Extension Option Rider). The First Offer Space Rent payable for any
Special First Offer Space leased by Tenant pursuant to Sections 1.5.1.1 and/or
1.5.1.2 above shall be equal to the Fair Market Rental Rate for such Special
First Offer Space. The Base Year used for determining Tenant's obligations to
pay Direct Expenses for any such Post-Third Year Offer Space and Special First
Offer Space leased by Tenant hereunder shall be the calendar year in which the
First Offer Commencement Date therefor occurs; provided, however, that if the
First Offer Commencement Date for such Post-Third Year Offer Space or Special
First Offer Space, as the case may be, occurs after the month of September of
such calendar year, then the Base Year therefor shall be the calendar year
immediately following the calendar year in which such First Offer Commencement
Date occurs. All of the other terms of the lease for such applicable Post-Third
Year Offer Space and Special First Offer Space, as the case may be, shall be
upon the same terms and conditions of this Lease as applicable to the original
Premises, except that (i) the Tenant Work Letter and Tenant Improvement
Allowance set forth therein shall not apply with respect to any such Post-Third
Year Offer Space leased by Tenant hereunder (as the tenant improvement allowance
for such Post-Third Year Offer Space shall be determined as a component of the
Fair Market Rental Rate therefor as set forth in Section 1.5.2 above), (ii) the
Tenant Work Letter and tenant improvement allowance for the Special First Offer
Space leased by Tenant pursuant to Sections 1.5.1.1 and/or 1.5.1.2 above shall
be as set forth in Section 1.5.2(iii) above, and (iii) Tenant's Share shall be
increased to take into account the rentable square feet of such Post-Third Year
Offer Space or Special First Offer Space, as the case may be leased by Tenant
hereunder. Tenant shall be entitled to rent, at the prevailing parking rates, if
any, charged by Landlord or Landlord's parking operator from time to time as set
forth in Section 24.2 below, additional parking spaces in such locations within
the Parking Facilities as Landlord shall determine from time to time, at the
ratio

                                      -7-
<PAGE>

of four (4) parking spaces for each 1,000 rentable square feet of any
Post-Third Year Offer Space and Special First Offer Space so leased by Tenant;
five percent (5%) of such parking spaces shall be reserved for Tenant's use in
such locations in the Parking Facilities as shall be reasonably determined by
Landlord from time to time, while the remainder shall be unreserved,
undesignated parking spaces.

               1.5.3 PROCEDURE FOR ACCEPTANCE. On or before the date which is
ten (10) business days after Tenant's receipt of Landlord's First Offer Notice
(the "ELECTION DATE") (such ten (10) business day period shall be reduced to
five (5) business days with respect to Landlord's First Offer Notice for any
Special First Offer Space described in Section 1.5.1 above), Tenant shall
deliver written notice to Landlord ("TENANT'S ELECTION NOTICE") pursuant to
which Tenant shall have the right to elect either to: (i) lease the entire First
Offer Space described in the First Offer Notice (or with respect to any space
other than the First Floor First Offer Space, such contiguous full floor(s)
thereof as described in Section 1.5.1(B) above) at the First Offer Space Rent
and upon the other terms therefor set forth in the First Offer Notice (if Tenant
desires to lease less then the entire First Offer Space pursuant to this clause
(i) or clause (ii) hereinbelow, Tenant shall designate in Tenant's Election
Notice which contiguous full floor portion(s) thereof Tenant so desires to lease
pursuant to Section 1.5.1(B) above, but if Tenant fails to indicate its desire
to lease less than the entire First Offer Space, Tenant shall be deemed to have
elected to lease the entire First Offer Space); (ii) lease the entire First
Offer Space (or, with respect to any space other than the First Floor First
Offer Space, such contiguous full floor(s) thereof as described in Section
1.5.1(B) above) upon the terms set forth in the First Offer Notice, except that
Tenant may concurrently object to Landlord's determination of the Fair Market
Allowance with respect to any Pre-Third Year Offer Space or the Fair Market
Rental Rate for any Post-Third Year Offer Space, as the case may be; provided
that not timely objecting to Landlord's determination of the Fair Market
Allowance or the Fair Market Rental Rate, as applicable, shall be deemed
Tenant's acceptance of same; or (iii) refuse to lease the entire or any such
contiguous full floor portions of the First Offer Space identified in the First
Offer Notice. If Tenant does not respond in writing to Landlord's First Offer
Notice by the Election Date, Tenant shall be deemed to have elected not to lease
any of such First Offer Space. If Tenant elects or is deemed to have elected not
to lease any of such First Offer Space, then Tenant's right of first offer set
forth in this Section 1.5 shall terminate with respect to all of the First Offer
Space specified in the First Offer Notice and Landlord shall thereafter have the
right to lease all or any portion of such First Offer Space to anyone to whom
Landlord desires on any terms Landlord desires; provided, however, Tenant shall
have a subsequent right of first offer to lease the applicable First Offer Space
identified in such First Offer Notice if such First Offer Space subsequently
becomes available for lease (as reasonably determined by Landlord) during the
First Offer Eligibility Period (A) after Landlord has entered into a subsequent
lease for such First Offer Space with a third party or third parties following
Tenant's failure to exercise such first offer right with respect to such space
and the expiration or earlier termination of the original Third Party Lease
therefor (including renewals, whether or not such renewal is pursuant to an
express provision in such lease or otherwise), and (B) following the expiration
or earlier termination of such subsequent third party lease and after the
applicable third party has vacated such space. If Tenant elects to lease the
entire First Offer Space, or with respect to any space other than the First
Floor First Offer Space, contiguous full floor(s) thereof identified in the
First Offer Notice, but objects to Landlord's determination of the Fair Market
Allowance or the Fair Market Rental Rate, as applicable, for the applicable
First Offer Space pursuant to clause (ii) hereinabove, then Landlord and Tenant
shall use the procedure set forth in Section 4 of the Extension Option Rider to
determine such Fair Market Rental Rate and/or Fair Market Allowance, as
applicable.

               1.5.4 AMENDMENT TO LEASE. If Tenant timely and validly exercises
its right of first offer to lease any First Offer Space pursuant to this
Section 1.5: (i) the applicable First Offer Space shall become part of the
Premises leased by Tenant under this Lease as of the applicable First Offer
Commencement Date therefor, pursuant to the terms of this Section 1.5 and the
other terms of this Lease which are not inconsistent therewith; (ii) with
respect to any space other than the Special First Offer Space leased by Tenant
pursuant to Sections 1.5.1.1 and/or 1.5.1.2 above, Landlord shall deliver the
applicable First Offer Space to Tenant on a date selected by Landlord (the
"PROJECTED DELIVERY DATE") that is no sooner than ninety (90) days and no later
than one (1) year after the date Landlord delivered to Tenant the applicable
First Offer Notice to Tenant, which outside Projected Delivery Date shall be
extended until the date the existing tenant vacates and surrenders possession of
such First Offer Space to Landlord; Landlord shall not be liable to Tenant or
otherwise be in default under this Lease if Landlord is

                                      -8-
<PAGE>

unable to deliver the applicable First Offer Space to Tenant by the outside
Projected Delivery Date due to the failure of any other tenant to timely vacate
and surrender to landlord such First Offer Space or any portion thereof (with
respect to any First Offer Space which is Special First Offer Space, the
foregoing provisions of this clause (ii) shall not apply, as Landlord shall
deliver the Special First Offer Space following the date Landlord substantially
completes the tenant improvements therefor in accordance with the provisions of
Section 1.5.2(iii) above); and (iii) Landlord and Tenant shall promptly after
such exercise by Tenant execute an amendment to this Lease covering the First
Offer Space and the lease terms thereof. The lease term for the applicable First
Offer Space so leased by Tenant (which is other than the Special First Offer
Space leased by Tenant pursuant to Sections 1.5.1.1 and/or 1.5.1.2 above), shall
commence upon the date (the "FIRST OFFER COMMENCEMENT DATE") which is the
earlier of (A) the date Tenant commences business operations in such First Offer
Space or (B) the date which is forty-five (45) days after Landlord's delivery of
such First Offer Space to Tenant in its "AS-IS" condition as set forth above.
The lease term for any Special First Offer Space leased by Tenant pursuant to
Sections 1.5.1.1 and/or 1.5.1.2 above shall commence upon the First Offer
Commencement Date therefor, which date shall, notwithstanding the immediately
preceding sentence to the contrary, be the earlier of (1) the date Tenant
commences business operations in such Special First Offer Space or (2) the date
Landlord substantially completes the tenant improvements for such Special First
Offer Space (subject to acceleration for any Tenant caused delays as provided in
the tenant work letter for such Special First Offer Space).

               1.5.5 SUSPENSION OF RIGHT OF FIRST OFFER. Notwithstanding
anything in the foregoing to the contrary, at Landlord's option, and in addition
to all of Landlord's remedies under this Lease, at law or in equity, the right
of first offer herein above granted to Tenant shall not be deemed to be properly
exercised if, as of the date Tenant exercises its right of first offer, Tenant
is in monetary or material non-monetary default under this Lease beyond any
applicable notice and cure period; provided, however, that Tenant shall be
entitled to an additional five (5) business days from the date of Tenant's
receipt of Landlord's notice to cure any such monetary or material non-monetary
default in order to preserve Tenant's first offer right so exercised by Tenant
to lease the applicable First Offer Space thereunder. In addition, Tenant's
right of first offer to lease the First Offer Space is personal to the original
tenant executing this Lease (the "ORIGINAL TENANT") and any assignee (including
an Affiliate) to which Tenant's entire interest in this Lease has been assigned
pursuant to Article 14 of this Lease (and not by any sublessee or other
transferee of Tenant's interest in the Lease), and shall only be available to
and exercisable by the Tenant when the Original Tenant or such assignee is in
actual and physical possession of all of the rentable area located in
Building B.

     1.6  FHS EXPANSION SPACE. Landlord hereby grants to Tenant the right to
lease between approximately 100,000 and 125,000 rentable square feet of space,
which space (the "FHS EXPANSION SPACE") shall be located, at Landlord's sole
election, either (i) entirely in an existing building in the Project (a
"PRE-EXISTING BUILDING") or (ii) entirely in a new building to be constructed by
Landlord and added to the Project (a "NEW BUILDING"), upon the terms and
conditions set forth in this Section 1.6. The precise amount of the FHS
Expansion Space (within such rentable square footage parameters) and the exact
location of the FHS Expansion Space shall be designated by Landlord (it being
acknowledged that the FHS Expansion Space must be contiguous space if located in
a New Building, or in a Pre-Existing Building which is other than Building C,
but may or may not be contiguous space if located in Building C, as determined
by Landlord in Landlord's sole discretion). In the event that Tenant exercises
its rights under this Section 1.6, the Original Tenant, and/or Foundation Health
Systems ("FHS") through a sublease entered into by Tenant and FHS pursuant to
the following provisions of this Section 1.6, shall initially occupy the FHS
Expansion Space. In the event that Tenant subleases to FHS all or any portion of
the FHS Expansion Space, Landlord shall have no right to consent to such
sublease, provided that (A) Tenant gives Landlord at least ten (10) days' prior
notice of any such sublease, (B) any such sublease shall be subject and
subordinate to all of the terms and provisions of this Lease and FHS shall
expressly assume, in a written sublease delivered to Landlord on or prior to the
effective date of such sublease, all of the obligations of Tenant under this
Lease with respect to the FHS Expansion Space subleased to FHS (other than the
amount of Base Rent payable by FHS with respect to such sublease), and (C)
Tenant shall remain fully liable for all obligations to be performed by Tenant
under this Lease.

          1.6.1 METHOD OF EXERCISE. The expansion option contained in this
Section 1.6 shall be exercised by Tenant only in the following manner:

                                      -9-
<PAGE>


          (i)  Tenant shall deliver written notice to Landlord ("TENANT'S FHS
INTEREST NOTICE") not later than June 1, 2002, stating that Tenant may be
interested in exercising its expansion option;

          (ii) Landlord, within ninety (90) days after receipt of Tenant's FHS
Interest Notice, shall deliver notice (the "FHS EXPANSION RENT NOTICE") to
Tenant setting forth (A) whether the FHS Expansion Space will be located in a
Pre-Existing Building or New Building and, in either case, the approximate
location of the space Landlord shall designate as the FHS Expansion Space, if
leased by Tenant, (B) the approximate rentable and usable square footage of the
space Landlord shall designate as the FHS Expansion Space, which shall be not
less than approximately 100,000 rentable square feet and not more than
approximately 125,000 rentable square feet, (C) in the event that the FHS
Expansion Space shall be located in a Pre-Existing Building, Landlord's
determination of the Fair Market Rental Rate (as defined in the Extension Option
Rider attached hereto) for the FHS Expansion Space, (D) in the event the FHS
Expansion Space shall be located in a New Building, Landlord's estimate of the
Total New FHS Building Costs and the estimated annual Base Rent payable by
Tenant therefor based upon and in accordance with the yield on cost formula set
forth in Section 1.6.4 below, and (E) Landlord's estimate of the date Landlord
will deliver possession of the FHS Expansion Space to Tenant pursuant to Section
1.6.2 below; provided, however, if Tenant delivers Tenant's FHS Interest Notice
at any time during the period from and after March 1, 2002 through and including
June 1, 2002, then, notwithstanding anything to the contrary set forth in this
Section 1.6, (1) Landlord shall have until September 1, 2002 to deliver to
Tenant the FHS Expansion Rent Notice described above, and (2) if Landlord
determines that the FHS Expansion Space will be located in a New Building, the
Base Rent payable by Tenant for the FHS Expansion Space in the New Building
shall be calculated based upon the lesser of (x) the actual Total New FHS
Building Costs incurred by Landlord therefor or (y) the estimated Total New FHS
Building Costs set forth in Landlord's FHS Expansion Rent Notice (including
reserves and contingencies), as such estimated amounts may be increased to the
extent such estimates are based on dates or other factors which are variable in
nature (e.g., interest, financing and carrying costs which vary based upon the
length of the construction process and/or the actual date of substantial
completion and delivery of the FHS Expansion Space) and/or due to acts or
omissions of Tenant or Tenant's agents, employees or contractors, including any
Tenant Delays and/or changes in the base, shell and core of the New Building
required due to changes in the plans therefor proposed by Tenant or required in
connection with the tenant improvements for the FHS Expansion Space; and

          (iii) if Tenant wishes to exercise its expansion option for the FHS
Expansion Space designated by Landlord in the FHS Expansion Rent Notice, Tenant
shall, on or before the date occurring thirty (30) days after Tenant's receipt
of the FHS Expansion Rent Notice, exercise the expansion option by delivering
written notice thereof (the "FHS EXPANSION EXERCISE NOTICE") to Landlord, and,
in the event that the FHS Expansion Space shall be located in a Pre-Existing
Building as designated by Landlord, upon and concurrent with such exercise,
Tenant may, at its option, object to Landlord's determination of the Fair Market
Rental Rate for the FHS Expansion Space contained in the FHS Expansion Rent
Notice, in which case the parties shall follow the procedure and the Fair Market
Rental Rate for the FHS Expansion Space shall be determined as set forth in
Section 4 of the Extension Option Rider attached hereto. If Tenant does not
timely object to Landlord's determination of the Fair Market Rental Rate for the
FHS Expansion Space, Landlord's determination thereof shall be conclusive and
the arbitration procedures in Section 4 of the Extension Option Rider shall not
be applicable but only if the FHS Expansion Rent Notice so states.

          1.6.2 DELIVERY OF THE FHS EXPANSION SPACE. Promptly after Landlord
substantially completes Landlord's construction obligations for the FHS
Expansion Space as described in Section 1.6.5 below, Landlord shall deliver the
FHS Expansion Space to Tenant in the condition required in Section 1.6.5.
Landlord shall endeavor to so deliver the FHS Expansion Space on or prior to
October 1, 2004, but, subject to Section 1.6.5 below, Landlord shall not be
liable to Tenant nor shall Tenant have any right to terminate this Lease or
Tenant's lease of the FHS Expansion Space as a result of Landlord's failure to
so deliver the FHS Expansion Space by such date.

          1.6.3 TERMS OF TENANT'S LEASE OF THE FHS EXPANSION SPACE. In the event
that Landlord shall elect to locate the FHS Expansion Space in a Pre-Existing
Building, (i) the annual Base Rent payable by Tenant for the FHS Expansion Space
shall be equal to ninety-five percent (95%) of the Fair Market Rental Rate for
the FHS Expansion Space, and (ii) the term of

                                      -10-
<PAGE>

Tenant's lease of the FHS Expansion Space shall be eight (8) years commencing
upon the FHS Commencement Date (as defined below). In the event that Landlord
shall elect to locate the FHS Expansion Space in a New Building, (A) the annual
Base Rent payable by Tenant for the FHS Expansion Space shall be determined in
accordance with the yield on cost formula set forth in Section 1.6.4 below,
subject, however to the provisions in Section 1.6.1(ii) above, and (B) the term
of Tenant's lease of the FHS Expansion Space shall be ten (10) years commencing
upon the FHS Commencement Date. Regardless of whether Landlord elects to locate
the FHS Expansion Space in a Pre-Existing Building or a New Building, (1) the
Base Year used for determining Tenant's obligation to pay Direct Expenses for
the FHS Expansion Space shall be the calendar year in which the FHS Commencement
Date occurs (provided, however, that if the FHS Commencement Date occurs after
the month of September of such calendar year, then the Base Year therefor shall
be the calendar year immediately following the calendar year in which the FHS
Commencement Date occurs), and (2) Tenant shall be entitled to rent, at the
prevailing parking rates, if any, charged by Landlord or Landlord's parking
operator from time to time as set forth in Section 24.2 below, additional
parking spaces in such locations within the Parking Facilities as Landlord shall
determine from time to time, at the ratio of four (4) parking spaces for each
1,000 rentable square feet of the FHS Expansion Space so leased by Tenant; five
percent (5%) of such parking spaces shall be reserved for Tenant's use in such
locations in the Parking Facilities as shall be determined by Landlord from time
to time, while the remainder shall be unreserved, undesignated parking spaces.

          1.6.4 FHS BASE RENT FOR FHS EXPANSION SPACE IN NEW BUILDING.

               1.6.4.1 YIELD ON COST FORMULA. In the event that Landlord elects
to locate the FHS Expansion Space in a New Building, the annual Base Rent
payable by Tenant for the FHS Expansion Space for the first (1st) year of the
lease term therefor (the "FIRST YEAR FHS BASE RENT") shall equal an amount which
shall yield Landlord, on an annual basis during the initial lease term for the
FHS Expansion Space, a net revenue return on the Total New FHS Building Costs
(as defined below) per rentable square foot per year of the greater of (i)
eleven percent (11%) or (ii) the sum of (A) the Ten-Year Treasury Rate in effect
at the date of commencement of construction of the New Building plus (B) five
percent (5%). During each year of the initial lease term for the FHS Expansion
Space commencing with the second (2nd) year thereof, the annual Base Rent
payable for the FHS Expansion Space shall equal the First Year FHS Base Rent,
increased by two percent (2%) per year on a cumulative and compounded basis.

               1.6.4.2 TOTAL NEW FHS BUILDING COSTS. The term "TOTAL NEW FHS
BUILDING COSTS" shall mean the total of all soft and hard costs, determined
on a per rentable square foot basis based upon the rentable square feet of
the FHS Expansion Space in the New Building, paid or incurred by Landlord in
connection with the acquisition, design, construction and development of the
New Building and the FHS Expansion Space therein, and the related utilities,
parking structures, parking areas, site, infrastructure, streets, roadways,
driveways, plazas, courtyards, transportation facilitation areas, accessways
and common area improvements and facilities associated or constructed in
connection therewith (collectively, the "RELATED IMPROVEMENTS"); provided,
however, to the extent any of the Related Improvements are directly used by
or benefit any buildings located on the Real Property (or elsewhere) in
addition to the New Building, any such costs and expenses pertaining to the
Related Improvements shall be allocated on a pro-rata basis, as reasonably
determined by Landlord, to the Total New FHS Building Costs. The Total New
FHS Building Costs shall include, without limitation: (i) all architectural,
engineering, contractor, subcontractor, governmental, license, permit,
school, art, marketing, traffic impact, parking, sewer, utilities, legal and
accounting fees and expenses, and the cost of all labor, supplies and
materials; (ii) Landlord's costs and expenses related to acquiring the land
upon which the New Building and such Related Improvements are or shall be
constructed or located (which land costs and expenses the parties agree shall
equal the "Land Cost Amount" [as defined below] per square foot of land area
upon which the New Building and such Related Improvements are or shall be
constructed or located, and which land area for any land located outside the
New Building upon which any Related Improvements are located shall be
allocated to the land area of the land upon which the New Building is located
on a pro rata basis, as reasonably determined by Landlord, to the extent any
such Related Improvements are directly used by or benefit any buildings
located on the Real Property in addition to the New Building); (iii) any
costs incurred by Landlord for designing and constructing the initial tenant
improvements for the FHS Expansion Space and any tenant improvement allowance
provided by Landlord to Tenant in connection with Tenant's lease of the FHS
Expansion Space (collectively,

                                      -11-
<PAGE>


the "FHS TENANT IMPROVEMENT COSTS/ALLOWANCE"), provided, however, Landlord's
contribution for the FHS Tenant Improvement Costs/Allowance shall be fixed at
$35.00 per usable square foot of the FHS Expansion Space, and Tenant shall be
responsible for paying for all of the costs of the design and construction of
the initial tenant improvements for the FHS Expansion Space in excess of such
amount, which payment shall be made directly to Landlord during the design
and construction of the initial tenant improvements for the FHS Expansion
Space and not as a part of the annual Base Rent for the FHS Expansion Space
or the Total New FHS Building Costs; (iv) any interest expenses and tax and
insurance payments incurred during such construction process; (v) the cost of
grading, demolition, site work, lighting and landscaping; (vi) any loan or
mortgage fees and other financing costs; (vii) leasing commissions; (viii)
developer fees and development management fees; and (ix) any other costs,
fees or expenses incurred in connection with such acquisition, design,
construction and development. Without limitation, examples of some of the
line items and categories of the Total New FHS Building Costs are shown on
EXHIBIT J attached to this Lease. For purposes hereof, the "LAND COST AMOUNT"
shall equal the sum of (A) $45.00 per square foot of the applicable land
area, plus (B) all loan interest expenses and carrying costs incurred or
imputed by Landlord with respect to such land area during the period from the
date of mutual execution and delivery of this Lease until the FHS
Commencement Date.

               1.6.4.3 FINAL RENT NOTICE. Landlord shall deliver to Tenant a
notice (the "FINAL RENT NOTICE") indicating the actual amount of the Total New
FHS Building Costs and resulting annual Base Rent payable in connection
therewith based upon the foregoing yield on cost formula (and the provisions of
Section 1.6.1(ii) above) following Landlord's determination of same. If the
Final Rent Notice is delivered by Landlord to Tenant after the FHS Commencement
Date, then until such notice is delivered to Tenant, Tenant shall pay annual
Base Rent for the FHS Expansion Space pursuant to this Section 1.6.4 at the
estimated amount set forth in the FHS Expansion Rent Notice delivered by
Landlord to Tenant pursuant to Section 1.6.1 above, and within thirty (30) days
after delivery of the Final Rent Notice, Tenant shall pay to Landlord the total
amount of any underpayment of such annual Base Rent applicable to the period
from the FHS Commencement Date until such payment is made, or Landlord shall
credit against the annual Base Rent next coming due and payable for the FHS
Expansion Space any overpayment of such annual Base Rent actually paid by Tenant
applicable to such period.

               1.6.4.4 TOTAL NEW FHS BUILDING COSTS AUDIT RIGHT. In the event
Tenant disputes the actual amount of the Total New FHS Building Costs set forth
on the Final Rent Notice, Tenant shall have the right, at Tenant's cost, after
reasonable notice to Landlord, to have Tenant's authorized employees inspect, at
Landlord's office in Los Angeles and/or Orange Counties during normal business
hours, Landlord's books, records and supporting documents concerning the Total
New FHS Building Costs set forth on the Final Rent Notice; provided, however,
Tenant shall have no right to conduct such inspection, have an audit performed
by the FHS Building Accountant as described below, or object to or otherwise
dispute the amount of the Total New FHS Building Costs set forth on the Final
Rent Notice unless Tenant notifies Landlord of such objection and dispute,
completes such inspection, and has the FHS Building Accountant (as defined in
this Section 1.6.4.4 below) commence and complete such audit within one hundred
twenty (120) days following Landlord's delivery of the Final Rent Notice (the
"FHS REVIEW PERIOD"); provided, further, that notwithstanding any such timely
objection, dispute, inspection, and/or audit, and as a condition precedent to
Tenant's exercise of its right of objection, dispute, inspection and/or audit as
set forth in this Section 1.6.4.4, Tenant shall not be permitted to withhold
payment of, and Tenant shall timely pay to Landlord, the full amounts as
required by the provisions of this Section 1.6.4 in accordance with the Final
Rent Notice. However, such payment may be made under protest pending the
resolution of any such dispute pursuant to the following provisions of this
Section 1.6.4. In connection with any such inspection by Tenant, Landlord and
Tenant shall reasonably cooperate with each other so that such inspection can be
performed pursuant to a mutually acceptable schedule, in an expeditious manner
and without undue interference with Landlord's operation and management of the
Real Property. If after such inspection and/or request for documentation, Tenant
still disputes the amount of the Total New FHS Building Costs set forth in the
Final Rent Notice, Tenant shall have the right, within the FHS Review Period, to
cause an independent certified public accountant (which is not paid on a
commission or contingency basis) selected by Tenant and reasonably approved by
Landlord (the "FHS BUILDING ACCOUNTANT") to complete an audit of Landlord's
books and records to determine the amount of the Total New FHS Building Costs
incurred and the amount of the First Year FHS Base Rent. Such audit by the FHS
Building

                                      -12-
<PAGE>

Accountant shall be final and binding upon Landlord and Tenant, unless
Landlord objects thereto in a written notice delivered to Tenant within sixty
(60) days after Tenant delivers the results of such audit to Landlord. If
Landlord timely objects to the results of such audit, then the parties shall
promptly submit the dispute to binding arbitration under the auspices of
JAMS/ENDISPUTE (or any successor to such organization) in Los Angeles,
California, according to the then rules of commercial arbitration for such
organization but with reference to the Total New FHS Building Costs, and the
arbitrators resolving such dispute shall only have jurisdiction to determine the
Total New FHS Building Costs and corresponding First Year FHS Base Rent in
dispute, and shall not have jurisdiction to modify the terms of this Lease.
Within thirty (30) days following the resolution of such dispute based upon the
audit or binding arbitration, as the case may be, (i) if it is determined that
Tenant has overpaid Landlord for the First Year FHS Base Rent, Landlord shall
reimburse to Tenant the amount of such over-payment together with interest on
the amount of the over-payment at the Interest Rate (as defined in Section 4.5
below), or (ii) if it is determined that Tenant has underpaid Landlord for the
First Year FHS Base Rent, Tenant shall pay to Landlord the amount of such
under-payment (without interest). Tenant agrees to pay the cost of such audit
unless it is subsequently determined pursuant to this Section 1.6.4.4 that
Landlord's Final Rent Notice overstated the Total New FHS Building Costs by four
percent (4%) or more of the actual Total New FHS Building Costs. The payment by
Tenant of any amounts pursuant to this Section 1.6.4.4 shall not preclude Tenant
from questioning, during the FHS Review Period, the correctness of the Final
Rent Notice, but the failure of Tenant to object thereto, conduct and complete
its inspection and have the FHS Building Accountant conduct the audit as
described above prior to the expiration of the FHS Review Period shall be
conclusively deemed Tenant's approval of the Final Rent Notice and the amount of
the Total New FHS Building Costs set forth thereon. If following Tenant's
delivery to Landlord of a written request to make Landlord's books and records
regarding the Total New FHS Building Costs reasonably available to Tenant and/or
the FHS Building Accountant to conduct any such inspection and/or audit
described above in this Section 1.6.4.4, Landlord fails to make Landlord's books
reasonably available for such purposes during Landlord's normal business hours,
and such failure continues for one (1) business day after Tenant notifies
Landlord thereof, then the FHS Review Period shall be extended one (1) day for
each such day that Tenant and/or the FHS Building Accountant, as the case may
be, is so prevented from accessing such books and records. In connection with
any inspection and/or audit conducted by Tenant pursuant to this Section
1.6.4.4, Tenant agrees to keep, and to cause all of Tenant's employees and
consultants and the FHS Building Accountant to keep, all of Landlord's books and
records and the audit, and all information pertaining thereto and the results
thereof, strictly confidential (except if required by any court to disclose such
information or if such information is available from an inspection of public
records or as otherwise may be necessary for Tenant to enforce its rights under
this Lease), and in connection therewith, Tenant shall cause such employees,
consultants and the FHS Building Accountant to execute such reasonable
confidentiality agreements as Landlord may require prior to conducting any such
inspections and/or audits.

               1.6.5 CONSTRUCTION IN FHS EXPANSION SPACE. If Tenant leases the
FHS Expansion Space pursuant to the terms of this Section 1.6, Landlord shall
deliver the FHS Expansion Space to Tenant following the date Landlord
substantially completes the base, shell and core and the initial tenant
improvements for the FHS Expansion Space (to the extent the FHS Expansion Space
is in an Existing Building and the base, shell and core of the Existing Building
has been constructed, Landlord shall have no obligation to construct the base,
shell and core of the Existing Building). If the FHS Expansion Space is located
in a New Building, the plans and specifications for the base, shell and core
thereof shall be developed by Landlord in the exercise of Landlord's sole
discretion; provided, however, that the base, shell and core for the New
Building shall be substantially similar to the Base, Shell and Core for the
Buildings (except for changes required by applicable Laws or governmental
authorities or to comply with any covenants, conditions or restrictions recorded
against the Real Property, and except that the finishes, number of floors and
rentable/usable square footage for the New Building may be different, at
Landlord's discretion), and, to the extent that Landlord anticipates that the
base, shell and core for the New Building shall be substantially different from
the Base, Shell and Core for the Buildings, Landlord shall describe such
differences in the FHS Expansion Rent Notice. Tenant shall pay for the costs of
the design and construction of the initial tenant improvements for the FHS
Expansion Space, subject to Landlord's contribution of a tenant improvement
allowance therefor. If the FHS Expansion Space is located in a Pre-Existing
Building, such tenant improvement allowance shall be determined as part of the
Fair Market Rental Rate for the FHS Expansion Space; if the FHS Expansion Space
is located in a New Building, such tenant

                                      -13-
<PAGE>

improvement allowance shall be an amount equal to $35.00 per usable square foot
of the FHS Expansion Space. Landlord shall be responsible for constructing the
tenant improvements for the FHS Expansion Space (and the base, shell and core if
not already constructed for the FHS Expansion Space if located in the New
Building) pursuant to a tenant work letter substantially the same as the Tenant
Work Letter attached to this Lease as Exhibit B, except that: (i) the time
deadlines for submittal and approval of plans and specifications and other
actions required to be performed by Landlord and Tenant (including staged
delivery of floors, if applicable) shall be revised with respect to the FHS
Expansion Space pursuant to a schedule mutually approved by the parties and set
forth in the amendment to Lease (or separate lease) described in Section 1.6.7
below; (ii) Sections 5.4, 5.5.2 and 5.5.3 of the Tenant Work Letter shall not
apply with respect to the FHS Expansion Space; (iii) Tenant's termination right
in Section 5.5.1 of the Tenant Work Letter shall apply with respect to the FHS
Expansion Space, but shall be revised such that (A) the Second Outside Date
referenced therein shall mean January 1, 2006 with respect to the FHS Expansion
Space, and (B) such termination right provided to Tenant in connection with the
FHS Expansion Space shall be limited to the termination of Tenant's proposed
lease of the FHS Expansion Space, only, and shall not include any right to
terminate this Lease with respect to the original Premises or any other space
leased by Tenant; (iv) the definition of the base, shell and core for the FHS
Expansion Space shall be as determined by Landlord as set forth hereinabove; (v)
the tenant improvement allowance for the FHS Expansion Space shall be determined
as set forth hereinabove, and, unless otherwise mutually agreed to by Landlord
and Tenant, Tenant shall not be entitled to use any portion of such tenant
improvement allowance for any of Tenant's Property or Moving/Personal Property
Costs as provided in the Tenant Work Letter; (vi) the fixed fees and general
conditions for the Contractor if Landlord selects Snyder Langston as the
Contractor currently set forth in the Tenant Work Letter, and the provisions
requiring Landlord to enter into a guaranteed maximum construction contract with
the Contractor shall not apply with respect to the FHS Expansion Space unless
otherwise mutually approved by Landlord and Tenant; and (vii) the terms and
conditions of the Tenant Work Letter attached to this Lease which conflict with
the terms and conditions of this Section 1.6.5 shall not apply.

               1.6.6 FHS COMMENCEMENT DATE. As used herein, the "FHS
COMMENCEMENT DATE" shall mean the date which is the earlier of: (i) the date
Tenant commences business operations in all or any portion of the FHS Expansion
Space; and (ii) the later of (A) the date of substantial completion (as defined
in the Tenant Work Letter for the FHS Expansion Space) of the FHS Expansion
Space, as such date shall be accelerated for Tenant caused delays pertaining to
the FHS Expansion Space, or (B) January 1, 2005.

               1.6.7 AMENDMENT TO LEASE. If Tenant timely exercises Tenant's
right to lease the FHS Expansion Space as set forth herein, Landlord and Tenant
shall promptly thereafter execute an amendment to this Lease memorializing
Tenant's lease of the FHS Expansion Space upon the terms and conditions set
forth in this Section 1.6. Such amendment shall modify (i) the definition of
"Buildings" set forth in Section 6.1 of the Summary to include in such
definition the building in which the FHS Expansion Space is located if such FHS
Expansion Space is located in any building which is other than Building C, and
(ii) such other provisions of this Lease as is reasonably necessary to cause any
terms and conditions set forth in this Lease to also apply to the building in
which the FHS Expansion Space is located if not located in Building C.
Notwithstanding the foregoing, in lieu of such an amendment to this Lease,
Landlord may, at its election, provide for Tenant's lease of the FHS Expansion
Space in a separate lease, independent from this Lease, upon all of the terms
and conditions contained in this Section 1.6 and any other provisions of this
Lease (excluding Section 14.8 of this Lease which shall not apply to the FHS
Expansion Space) which do not conflict with this Section 1.6 and are applicable
to the FHS Expansion Space, and Tenant shall execute such separate lease
promptly following Landlord's delivery of same to Tenant. Further, Tenant agrees
that in connection with Landlord's financing, transfer or sale of all or any
portion of the Real Property, or for any other reason determined by Landlord,
Landlord may, at any time after execution of this Lease, remove this Section 1.6
(and Landlord's obligations hereunder) from this Lease and instead include the
provisions of this Section 1.6 and Landlord's obligations and Tenant's rights
hereunder in a separate written agreement independent from this Lease (which
separate agreement shall, at Landlord's election, only pertain to such portions
of the Real Property [which may be less than the entire Real Property] owned by
Landlord and designated by Landlord to be the property upon which Landlord shall
provide the FHS Expansion Space to Tenant if Tenant exercises its right to lease
the FHS Expansion Space hereunder). Tenant shall promptly execute such separate
agreement, as well as an amendment to this Lease deleting this Section 1.6
therefrom (and otherwise

                                      -14-
<PAGE>

modifying this Lease to delete any references to Section 1.6 and the FHS
Expansion Space), following Landlord's election and submission of such documents
to Tenant, provided that the form and substance of such separate agreement and
amendment to Lease are reasonably acceptable to Tenant. Landlord agrees that the
execution of any such separate agreement or separate lease described hereinabove
shall not relieve Landlord of its obligations to pay any brokerage commissions
to Tenant's Broker (as defined in Section 25.25 below) to the extent Landlord
would have been obligated to pay such commissions to Tenant's Broker pursuant to
Section 25.25 had such separate agreement and/or separate lease not been so
executed.

               1.6.8 SUSPENSION OF FHS EXPANSION SPACE RIGHT. Notwithstanding
anything to the contrary contained in this Section 1.6, the rights to lease the
FHS Expansion Space contained in this Section 1.6 are personal to the Original
Tenant and any Affiliate to which Tenant's entire interest in this Lease has
been assigned pursuant to Section 14.7 below, and may not be assigned or
exercised, voluntarily or involuntarily, to or by, any other person or entity
other than the Original Tenant or such Affiliate assignee, as the case may be.
In addition, at Landlord's option, and in addition to all of Landlord's remedies
under this Lease, at law or in equity, Tenant shall not have the right to lease
the FHS Expansion Space as provided in this Section 1.6 if, as of the date of
the attempted exercise of such expansion right by Tenant, Tenant is in monetary
default or material non-monetary default under this Lease beyond any applicable
notice and cure periods; provided, however, that Tenant shall be entitled to an
additional five (5) business days from the date of Tenant's receipt of
Landlord's notice to cure any such monetary or material non-monetary default in
order to preserve Tenant's FHS Expansion Option exercised by Tenant.

     1.7  TENANT'S REDUCTION RIGHT. During the first six (6) years of the Lease
Term, Tenant shall have five (5) separate rights (each, a "REDUCTION RIGHT") to
reduce the rentable square feet of the Premises then leased by Tenant in
Building C upon the terms and conditions set forth in this Section 1.7.

          1.7.1 REDUCTION SPACE. Each such Reduction Right shall pertain to
one-half (1/2) contiguous full floor increments of space in Building C, starting
with the lowest floor then leased by Tenant in Building C, except that: (i) the
first (1st) Reduction Right shall pertain to either one-half (1/2) of a full
floor or a full floor, as elected by Tenant; (ii) if Tenant does not exercise a
Reduction Right for any particular one-year period, the amount of space which
Tenant may elect to reduce pursuant to Tenant's next applicable Reduction Right
shall include, at Tenant's election, an additional one-half (1/2) contiguous
floor increment of space (provided, however, in no event may Tenant elect to
reduce the Premises in any one-year period by more than one (1) contiguous full
floor); and (iii) in no event shall the total cumulative space which Tenant may
reduce in Building C pursuant to the exercise of all of Tenant's Reduction
Rights under this Section 1.7 exceed two and one-half (1/2) floors. In addition,
if at any time Tenant exercises a Reduction Right with respect to one-half (1/2)
of a particular floor in Building C, the next time Tenant elects to exercise a
Reduction Right, Tenant must include in the exercise of such right the remaining
one-half (1/2) of the space on such floor. The applicable space for which Tenant
has elected to exercise any Reduction Right shall be referred to herein as the
"REDUCTION SPACE".

          1.7.2 PROCEDURE. Each applicable Reduction Right shall be exercised by
Tenant, if at all, by delivering to Landlord written notice thereof (each, a
"REDUCTION NOTICE") on or before the following applicable dates (each, a
"REDUCTION EXERCISE DATE"), which Reduction Notice shall include Tenant's
determination of the amount and a floor plan depicting the location of the
applicable Reduction Space for which Tenant is exercising its applicable
Reduction Right, and if Tenant timely delivers to Landlord a Reduction Notice
with respect to any applicable Reduction Right, then this Lease shall terminate
with respect to the applicable Reduction Space upon the following applicable
delivery date therefor (each, a "REDUCTION DELIVERY DATE"):

However, if the Lease Commencement is later than January 1, 2002, then each
Reduction Exercise Date and Reduction Delivery Date shall be extended
day-for-day for each day after January 1, 2002 that the Lease Commencement
occurs. As consideration to Landlord for the exercise by Tenant of any such
Reduction Right, Tenant shall deliver to Landlord, on or prior to the applicable
Reduction Delivery Date, cash in the amount of the "Reduction Consideration" (as
defined below), payable with respect to the Reduction Space for which Tenant is
exercising such Reduction Right. As used herein, the "REDUCTION CONSIDERATION"
for each applicable Reduction Space shall mean the sum of: (A) the costs to be
incurred by Landlord to separately demise the Reduction Space from the remainder
of the Premises on such floor if such Reduction Space pertains to the first
one-half (1/2) of floor space reduced on such floor (as reasonably estimated by
Landlord), excluding, however, costs of the wall coverings to finish the
non-common area sides of the corridor walls and any other tenant improvements
constructed for the tenants of the Reduction Space; plus (B) the unamortized
amount of the Tenant Improvement Allowance and brokerage commissions paid or
incurred by Landlord with respect to such Reduction Space as determined by
Landlord on a pro-rata per square foot basis, and such pro-rata amount shall be
amortized on a straight-line basis, together with interest at the rate of ten
percent (10%) per annum, over the scheduled initial Lease Term for such
Reduction Space, and the unamortized amount shall be calculated based upon the
unexpired portion of the initial Lease Term which would have been remaining as
of the applicable Reduction Delivery Date had Tenant not exercised its Reduction
Right for such Reduction Space. Landlord shall notify Tenant of the amount of
the applicable Termination Consideration for each Reduction Space at least
thirty (30) days prior to the applicable Reduction Delivery Date.

          1.7.3 AMENDMENT TO LEASE. If Tenant timely exercises its Reduction
Right for any Reduction Space hereunder, (i) this Lease shall terminate with
respect to such Reduction Space upon the applicable Reduction Delivery Date
therefor, and Tenant shall vacate and surrender exclusive possession of such
Reduction Space to Landlord on or before such Reduction Delivery Date in the
condition required in Article 15 below, and (ii) Landlord and Tenant shall
promptly execute an amendment to this Lease reducing such Reduction Space from
the Premises leased in Building C under this Lease. All provisions of this Lease
which vary based upon the rentable and usable square footage of the Premises
(including Base Rent, Tenant's Share and Tenant's allocated number of parking
spaces) shall be adjusted in such amendment to reflect the reduction of such
Reduction Space from the Premises.

                                   LEASE TERM

     2.1  TERM. The terms and provisions of this Lease shall be effective as of
the date of this Lease except for the provisions of this Lease relating to the
payment of Rent or as otherwise stated in this Lease (for example, Tenant shall
have no obligation to obtain insurance until the Insurance Start Date, as
defined in Section 10.3 below, and Tenant's indemnity of Landlord in Section
10.1.1(i) below with respect to any occurrences in the Premises not resulting
from the acts, omissions or negligence of Tenant or Tenant's contractors,
agents, servants, employees, licensees or invitees, shall not be applicable
until the Insurance Start Date). The term of this Lease (the "LEASE TERM") shall
be as set forth in Section 7.1 of the Summary and shall commence on the date
(the "LEASE COMMENCEMENT DATE") set forth in Section 7.2 of the Summary subject,
however, to the terms of the Tenant Work Letter, and shall terminate on the date
(the "LEASE EXPIRATION DATE") set forth in Section 7.3 of the Summary, unless
this Lease is sooner terminated as hereinafter provided or extended pursuant to
the Extension Option Rider attached to this Lease. For purposes of this Lease,
the term "LEASE YEAR" shall mean each consecutive twelve (12) month period
during the Lease Term, provided that the last Lease Year shall end on the Lease
Expiration Date. Promptly following the Lease Commencement Date, Landlord shall
execute and deliver to Tenant an amendment in the form as set forth in EXHIBIT
C, attached hereto, which amendment Tenant shall execute and return to Landlord
within fifteen (15) business days after receipt thereof.

     2.2  EARLY OCCUPANCY. Tenant shall have the right to occupy and commence
business operations in portions or all of the Premises, at any time after
Landlord has delivered such portion of the Premises in the applicable Delivery
Condition therefor (as defined in the Tenant Work Letter), but prior to the
Lease Commencement Date (the "PRE-OCCUPANCY PERIOD"), provided that (i)
Substantial Completion (as such term is defined in the Tenant Work Letter) of
such portion of the Premises shall have occurred, (ii) Tenant has installed
Tenant's Fixturizing Work (as defined in the Tenant Work Letter) in such portion
of the Premises in compliance with all applicable Laws and the Approved Working
Drawings therefor, (iii) such occupancy and business operations do not interfere
with or delay Landlord's completion of construction of the Tenant Improvements
and Base, Shell and Core work for such portion of the Premises occupied by
Tenant and/or the remainder of the Premises not so occupied by Tenant, (iv) a
temporary certificate of occupancy or its equivalent shall have been issued by
the appropriate governmental authorities for each such portion(s) of the
Premises to be occupied, and (v) during such occupancy of such portion(s) of the
Premises by Tenant, and until the Lease Commencement Date occurs, all of the
terms and conditions of this Lease shall apply, including, without limitation,
Tenant's obligation to pay to Landlord all sums and charges required to be paid
by Tenant under this Lease (including, without limitation (A) charges for
overstandard utilities consumed in such portions of the Premises so occupied
pursuant to Section 6.2 of this Lease and (B) charges for additional services
provided to such portions of the Premises so occupied pursuant to Section 6.4 of
this Lease), as though the Lease Commencement Date had occurred (although the
Lease Commencement Date shall not actually occur until the occurrence of the
same pursuant to the terms of Section 7.2 of the Summary); provided however,
during such Pre-Occupancy Period, (1) Tenant shall not be obligated to pay to
Landlord any Base Rent for the portion of the Premises so occupied, and (2)
Tenant shall be obligated to pay to Landlord a per diem amount equal to $0.01
per rentable square foot of the portion of the Premises so occupied by Tenant,
calculated on a half-floor or full-floor basis as described hereinbelow (the
"OCCUPANCY RENT"); provided, however, if the Lease Commencement Date has not
occurred during the Pre-Occupancy Period as a result of Force Majeure events,
then from and after the date during such Pre-Occupancy Period that the Lease
Commencement Date would have occurred but for such Force Majeure events, the per
diem Occupancy Rent amount set forth hereinabove shall be adjusted to equal
Tenant's Share of Direct Expenses with respect to the portions of the Premises
so occupied by Tenant, calculated on a half-floor or full-floor basis as
described hereinbelow and determined on a net basis (and not on a full service
gross basis) without regard to (or subtracting from such obligation the Direct
Expenses incurred in) the Base Year. For purposes of calculating the Occupancy
Rent payable by Tenant as defined hereinabove, (x) for each portion of a floor
so occupied by Tenant which is equal to or less than one-half (1/2) of such
floor, until Tenant occupied more than one-half (1/2) of such floor in which
case the provisions of clause (y) below shall then apply, Tenant shall be deemed
to have occupied one-half (1/2) of such floor, and the Occupancy Rent therefor
shall be determined based upon the rentable square feet of one-half (1/2) of
such floor upon which Tenant has occupied space (not just for the space on such
floor so occupied), (y) for each portion of a floor so occupied by Tenant which
is greater than one-half (1/2) of such floor, Tenant shall be deemed to have
occupied the entire floor, and the Occupancy Rent therefor shall be determined
based upon the rentable square feet of the entire floor upon which Tenant has
occupied space (not just the space on such floor so occupied), and (z) Tenant
shall be obligated to pay the Occupancy Rent for such half-floor or full floor
portion(s) of the Premises (as the case may be) during the entire part of the
Pre-Occupancy Period commencing as of the first day of occupancy by Tenant of
space on such floor which (I) with respect to clause (x) hereinabove pertains to
space which is equal to or less than one-half (1/2) floor, and (II) with respect
to clause (y) hereinabove, pertains to more than one-half (1/2) of such floor,
notwithstanding Tenant may thereafter cease occupancy of all or any portion (and
with respect to clause (y), less than one-half)_of such floor. Tenant's early
entry in the Premises to install Tenant's Fixturizing Work pursuant to the
Tenant Work Letter shall be set forth in and subject to the applicable
provisions of the Tenant Work Letter, which provisions shall not apply with
respect to Tenant's rights of early occupancy to commence business operations in
the Premises pursuant to this Section 2.2.

                                    ARTICLE 3

                                    BASE RENT

     Tenant shall pay, without notice or demand, to Landlord or Landlord's agent
at the management office of the Real Property, or at such other place as
Landlord may from time to

                                      -17-

time designate in writing, in currency, by wire transfer or a check for currency
which, at the time of payment, is legal tender for private or public debts in
the United States of America, base rent ("BASE RENT") as set forth in Section 8
of the Summary, payable in equal monthly installments as set forth in Section 8
of the Summary in advance on or before the first day of each and every month
during the Lease Term, without any setoff or deduction except as otherwise
expressly provided in this Lease. The Base Rent for the first (1st) full month
of the Lease Term shall be paid by Tenant to Landlord no later than June 30,
2001. If any rental payment date (including the Lease Commencement Date) falls
on a day of the month other than the first day of such month or if any rental
payment is for a period which is shorter than one month, then the rental for any
such fractional month shall be a proportionate amount of a full calendar month's
rental based on the proportion that the number of days in such fractional month
bears to the number of days in the calendar month during which such fractional
month occurs. All other payments or adjustments required to be made under the
terms of this Lease that require proration on a time basis shall be prorated on
the same basis. All increases in Base Rent set forth in Section 8 of the Summary
shall be tied to the applicable anniversary of the actual Lease Commencement
Date as set forth therein, and any time periods or specific dates for exercising
any rights or taking any action described in this Lease which are measured or
derived from the Lease Commencement shall be based upon the actual Lease
Commencement Date as determined pursuant to Section 7.2 of the Summary.

                                    ARTICLE 4

                                 ADDITIONAL RENT

     4.1  ADDITIONAL RENT. In addition to paying the Base Rent specified in
Article 3 of this Lease, Tenant shall pay to Landlord as additional rent the sum
of the following: (i) "Tenant's Building B Share" of the annual "Direct
Expenses" (as those terms are defined below in this Article 4) allocated to
Building B pursuant to Section 4.3.4, which are in excess of the amount of
Direct Expenses allocated to Building B and applicable to the "Base Year" (as
that term is defined below); plus (ii) "Tenant's Building C Share" (as such term
is defined below) of the annual Direct Expenses allocated to Building C pursuant
to Section 4.3.4, which are in excess of the amount of Direct Expenses allocated
to Building C and applicable to the Base Year. Tenant's Building B Share and
Tenant's Building C Share shall hereafter collectively be referred to as
"TENANT'S SHARE." Such additional rent, together with any and all other amounts
payable by Tenant to Landlord pursuant to the terms of this Lease, shall be
hereinafter collectively referred to as the "ADDITIONAL RENT." The Base Rent and
Additional Rent are herein collectively referred to as the "RENT." All amounts
due under this Article 4 as Additional Rent shall be payable for the same
periods and in the same manner, time and place as the Base Rent. Without
limitation on other obligations of Tenant which shall survive the expiration of
the Lease Term, but subject to the limitations set forth in Section 4.3.2 below,
the obligations of Tenant to pay the Additional Rent provided for in this
Article 4 shall survive the expiration of the Lease Term for a period of two (2)
years from the date of expiration or termination of this Lease.

specifically excluded from or subject to limitations on inclusion in Operating

not as a pass-through under such covenants, conditions or restrictions);
(x) operation, repair, maintenance and replacement of all "Systems and

amortization (including interest on the unamortized cost at the Amortization
Interest Rate) of the cost of any capital alterations, capital additions,

anticipated by Landlord to result therefrom, (II) made to the Real Property
after the Lease Commencement Date that are required under any governmental law
or regulation (or amendment thereof) not in effect on the Lease Commencement
Date (except as otherwise expressly provided in Section 4.2.5.1(q) below), (III)

first-class office building project (except that in no event shall the amortized
amount of the cost which Landlord may include in Operating Expenses pursuant to
this Section 4.2.5(xiii)(IV) exceed $100,000.00 in any particular Expense Year);
all such costs described in this Section 4.2.5(xiii) and the amortization of any
other capital expenditures under this Section 4.2.5 (including, without
limitation, Sections 4.2.5.1(q) and (v)

                                      -19-
<PAGE>

below) shall be amortized over the useful life of the particular capital item in
question as Landlord shall reasonably determine in accordance with standard real
estate management and accounting practices consistently applied by Landlord and
consistent with standard real estate management and accounting practices used by
landlords of ""Comparable Buildings (provided, however, that for purposes of
this Section 4.2.5, such amortization period with respect to any particular
capital expenditures having a cost in excess of $30,000.00 shall not be less
than five (5) years). As used herein, the "AMORTIZATION INTEREST RATE" shall
mean a rate equal to the floating commercial loan rate announced from time to
time by Bank of America, a national banking association, or its successor, as
its reference rate, plus one percent (1%) per annum.

     If, during all or any part of any Expense Year or the Base Year, Landlord
shall not furnish any particular items of work or service (the cost of which, if
performed by Landlord, would be included in Operating Expenses) to a tenant
(including Tenant) who has undertaken to perform such item of work or service in
lieu of the performance thereof by Landlord, Operating Expenses shall be deemed
to be increased by an amount equal to the additional Operating Expenses which
would reasonably have been incurred during such period by Landlord if Landlord
had at its own expense furnished such item of work or service to such tenant. In
addition, if Building B is less than 100% occupied and/or Building C (and during
the period of time when any other buildings are fully constructed and ready for
occupancy and are included by Landlord within the Project) is (are) less than
95% occupied during all or a portion of any Expense Year (including the Base
Year), Landlord shall make an appropriate adjustment to the variable components
of Operating Expenses for such year or applicable portion thereof, employing
sound accounting and management principles, to determine the amount of Operating
Expenses that would have been paid had Building B been 100% occupied and
Building C (and any of such other buildings, as applicable) been 95% occupied;
and the amount so determined shall be deemed to have been the amount of
Operating Expenses for such year, or applicable portion thereof. In determining
such adjustment pursuant to the immediately preceding sentence, any gross
receipts taxes, management fees or other expenses that are tied to the receipt
of rental income shall be determined as if the applicable buildings described
above were 100% or 95% occupied (as the case may be) during any Expense Year
(including the Base Year) and all tenants were paying the full rental initially
payable under their respective leases (as opposed to half-rent or abated rent).

     Subject to the provisions of Section 4.3.4 below, Landlord shall have the
right, from time to time, to equitably allocate some or all of the Direct
Expenses among the Buildings and the Existing Buildings and/or among different
tenants of the Project, and/or among different and additional buildings of the
Project, as and when such different and/or additional buildings are constructed
and added to (and/or excluded from) the Project or otherwise (collectively, the
"COST POOLS"). Such Cost Pools may include, but shall not be limited to, the
office space tenants and retail space tenants (and if applicable, child care
tenants or occupants) of the Project. Such Cost Pools may also include
allocation of certain Direct Expenses within or under covenants, conditions and
restrictions affecting the Project. In addition, Landlord shall have the right
from time to time, in its reasonable discretion, to include or exclude existing
or future buildings in the Project for purposes of determining Direct Expenses
and/or the provision of various services and amenities thereto, including
allocation of Direct Expenses in any such Cost Pools.

          4.2.5.1 Notwithstanding the foregoing, for purposes of this Lease,
Operating Expenses shall not include the following:

                    (a)  brokerage commissions, space planning costs, finders'
fees, attorneys' fees and other costs incurred by Landlord in connection with
leasing or attempting to lease space within the Real Property;

                    (b)  costs, including permit, license and inspection costs,
incurred with respect to the installation of tenant improvements made for any
tenants in the Real Property or incurred in renovating or otherwise improving,
decorating, painting or redecorating vacant space for tenants or other occupants
of the Real Property.

                    (c)  interest, points, fees and principal payments on any
mortgages encumbering the Real Property, and other debt costs, if any, except as
specifically included in Sections 4.2.5(xii) and (xiii) above and Sections
4.2.5.1(q) and (v) below;

                                      -20-

                    (d)  costs of correcting defects in, or significant design
error relating to, the initial design or construction of the Buildings, the
Phase I Parking Structure, the Parking Facilities or any other improvements to
the Real Property;

                    (e)  advertising and promotional expenditures;

                    (f)  costs of any items (including, but not limited to,
costs incurred by Landlord with respect to goods, services and utilities sold
and/or supplied to tenants and occupants of the Real Property, and/or for the
repair of damage to the Buildings for items which are reimbursable under any
contractor, manufacturer or supplier warranty) to the extent Landlord receives
reimbursement from insurance or condemnation proceeds or from a contractor,
manufacturer, supplier or any other third party (other than reimbursement by
tenants pursuant to the Operating Expenses pass-through provisions of their
leases); such proceeds shall be credited to Operating Expenses in the year in
which received;

                    (g)  expenses in connection with services or other benefits
which are not offered to Tenant or for which Tenant is charged directly but
which are provided to any other tenant or occupant of the Real Property at no
cost;

                    (h)  attorneys' fees and other costs and expenses incurred
in connection with negotiations or disputes with present or prospective tenants
or other occupants or prospective occupants of the Real Property (including
costs incurred due to violations by tenants of the terms and conditions of their
leases), or any other attorneys' fees incurred in connection with the Real
Property except (A) as specifically enumerated as an Operating Expense in this
Lease or (B) to the extent the expenditure of such attorneys' fees generally
benefits all of the tenants of the Real Property;

                    (i)  the wages and benefits of any employee who does not
devote substantially all of his or her employed time to the operation and
management of the Buildings or Real Property unless such wages and benefits are
prorated to reflect time spent on operating and managing the Buildings and Real
Property VIS-A-vis time spent on matters unrelated to operating and managing the
Buildings and Real Property;

                    (j)  compensation (including benefits) of any employee of
Landlord above the grade of Project manager or Project engineer;

                    (l)  rentals and other related expenses for leasing heating,
ventilation and air conditioning ("HVAC") systems, elevators, or other items
(except when needed in connection with normal repairs and maintenance of the
Buildings and/or Real Property and/or to an ameliorate an emergency condition in
the Buildings and/or Real Property) which if purchased, rather than rented,
would constitute a capital improvement not included in Operating Expenses
pursuant to this Lease;

                    (m)  costs and overhead and profit increment paid to
Landlord or to subsidiaries or affiliates of Landlord for goods and/or services
in or to the Real Property to the extent the same exceeds typical costs and

qualified unaffiliated third parties on a competitive basis;

                    (n)  any costs for which Landlord has been reimbursed (other
than through the Operating Expenses pass-through provisions of other tenants'
leases) or for which Landlord receives a credit, refund or discount;

                    (o)  costs of signs (other than building directories and
signage for various equipment rooms and common areas) in or on the Real Property
or any buildings located on the Real Property which identify the owner of the
Real Property or other tenants' signs;

                    (p)  costs incurred in installing, operating, and
maintaining any specialty service that is not necessary for Landlord's
provision, management, maintenance, and repair of required services for the
operation of the Real Property or any

                                      -21-
<PAGE>

associated Parking Facilities. The following are examples of these specialty
services: observatory; broadcasting facilities (other than the life-support and
security systems for the Buildings and Real Property); luncheon club, cafeteria,
or other dining facility; newsstand; flower service; shoeshine service; carwash;
athletic or recreational club; and helicopter pad (other than the Buildings' or
Real Property's emergency and life-safety helicopter facilities);

                    (q)  costs of cleanup, removal, investigation and/or
remediation (collectively, "REMEDIATION COSTS") of any Hazardous Materials (as
such term is defined in Article 5 below) in, on or under the Real Property
required to comply with Environmental Laws; notwithstanding the foregoing,
Landlord may include in Operating Expenses any such Remediation Costs which are
(1) incurred by Landlord after the Lease Commencement Date that are required to
comply with any Environmental Laws not in effect on the Lease Commencement Date
(but only with respect to Hazardous Materials located in Buildings B and C and
not any areas of the Real Property outside Buildings B and C), and (2) not the
result of the introduction by Landlord or any of Landlord's agents, employees,
contractors or tenants of the Real Property of any such Hazardous Materials in,
on or under the Real Property in violation of Environmental Laws in effect at
the time of such introduction (such Remediation Costs which may be so included
in Operating Expenses are collectively referred to herein as the "PERMITTED
REMEDIATION COSTS"), as follows: (A) Landlord may include in Operating Expenses
the first $1,000,000.00 of such Permitted Remediation Costs incurred, in the
aggregate, (B) Landlord shall have no right to include in Operating Expenses the
next $1,000,000.00 of such Permitted Remediation Costs so incurred, in the
aggregate, and (C) Landlord may include in Operating Expenses fifty percent
(50%) of those Permitted Remediation Costs so incurred which exceed
$2,000,000.00, in the aggregate (provided that to the extent that any of such
Permitted Remediation Costs are reasonably categorized as being costs for a
capital alteration, capital addition, capital repair or capital improvement,
such costs shall be amortized, together with interest at the Amortization
Interest Rate, in the manner described in Section 4.2.5(xiii) above); provided,
however, Landlord may not include any such Permitted Remediation Costs in
Operating Expenses to the extent such Permitted Remediation Costs are covered by
insurance maintained by Landlord as part of Operating Expenses unless and until
Landlord's insurance company denies coverage therefor despite Landlord's
commercially reasonable efforts to obtain proceeds therefor from such insurance
company;

                    (r)  interest, penalties or other costs arising out of
Landlord's failure to make timely payment of any of its obligations under this
Lease, including, without limitation, Landlord's failure to make timely payment
of any item that is included in Direct Expenses;

                    (s)  reserves of any kind, including replacement reserves
for bad debt loss or lost rent (but Operating Expenses may include reasonable
reserves imposed upon the Real Property as part of the assessments under any
covenants, conditions and restrictions recorded against the Real Property);

                    (t)  any costs expressly excluded from Operating Expenses
elsewhere in this Lease;

                    (u)  any ground lease rental;

                    (v)  depreciation and amortization, except as expressly
provided in this Section 4.2.5, and except on materials, tools, supplies and
vendor-type equipment purchased by Landlord to enable Landlord to supply
services Landlord might otherwise contract for with a third party, and when
depreciation or amortization is permitted or required, the item shall be
amortized over its useful life as determined by Landlord in the manner described
in Section 4.2.5(xiii) above, together with interest on the unamortized costs at
the Amortization Interest Rate;

                    (w)  costs (including, without limitation, fines, penalties,
interest, and costs of repairs, replacements, alterations and/or improvements)
incurred in bringing the Real Property into compliance with building codes and
other laws in effect as of the Lease Commencement Date and as interpreted by
applicable governmental authorities as of such date, including, without
limitation, any costs to correct building code violations pertaining to the
initial design or construction of the Buildings, the Phase I Parking Structure,
the Parking Facilities or any other improvements to the Real Property, to the
extent such violations exist as

                                      -22-
<PAGE>

of the Lease Commencement Date under any applicable building codes in effect and
as interpreted by applicable governmental authorities as of such date;

                    (x)  any and all costs incurred by Landlord in connection
with the transfer or disposition of Landlord's interest in any portion of the
Real Property, but the foregoing exclusion shall not apply to any real estate
tax expenses (other than documentary or local transfer taxes) resulting from or
otherwise imposed in connection with any such transfer or disposition, which
taxes may be included in Tax Expenses pursuant to Section 4.2.7 below;

                    (y)  costs incurred by Landlord due to the violation by
Landlord of the terms and conditions of any lease of space within the Real
Property;

                    (z)  Landlord's general corporate overhead, except as it
relates to the specific management of the Real Property;

                    (aa) costs arising out of the operation, management,
maintenance or repair of any retail premises in the Project or any other retail
areas operated by Landlord or its agents, contractors or vendors to the extent
such costs are uniquely attributable (and separately identifiable) to such
retail premises or areas (as opposed to general office use tenancies) or are
extraordinary, separately identifiable expenses arising in connection therewith;

                    (bb) any cost or expense solely and uniquely attributable
(and separately identifiable) to a building not leased, occupied or used by
Tenant and not part of the common areas of the Project (such as for example, any
repair costs for an office building leased to a single tenant other than Tenant,
unless such repair costs are pooled together under a common maintenance contract
for the Buildings and such other building);

                    (cc) any costs resulting from any condemnation pertaining to
the Real Property;

                    (dd) any costs or repair in excess of $25,000.00 resulting
from any casualty damage pertaining to the Real Property or any portion thereof,
including costs which are self-insured by Landlord or covered under an insurance
deductible obtained by Landlord;

                    (ee) any Tax Expenses or Utilities Costs.

               4.2.5.2 Landlord hereby agrees that the cost of any new type or
increased amount of insurance coverage (or increased limits of insurance or
decrease in the amount of deductibles) which is obtained or effected by Landlord
during any Expense Year after the Base Year (but is not obtained or effected
during the Base Year) shall be added to the Operating Expenses for the Base Year
(but at the rate which would have been in effect during the Base Year or the
rate in effect during such subsequent Expense Year, whichever is lower) prior to
the calculation of Tenant's Share of Operating Expenses for each such Expense
Year in which such change in insurance is obtained or effected.

               4.2.5.3 Landlord further agrees that any costs incurred in any
Expense Year after the Base Year because of any added new type of discretionary
services which were readily available during the Base Year and customarily
provided by landlords of Comparable Buildings during the Base Year (but not by
Landlord) and not included in the Base Year, shall be added to and included in
the Base Year for purposes of determining the Excess payable for such Expense
Year in which such added new type of discretionary services are so provided, as
if such services were provided in the Base Year (but at the rate for such
services which would have been in effect during the Base Year or the rate in
effect during such subsequent Expense Year, whichever is lower); provided,
however, the foregoing provision shall not apply to the costs of (i) any capital
additions, capital alterations, capital repairs or capital improvements which
shall be governed by the provisions of Sections 4.2.5 (xii) and (xiii) and
Sections 4.2.5.1 (k), (q) and (v) above, or (ii) security and/or parking control
services required to operate the Project as a first-class office building
project and added as a result of the expansion of the Project to include
additional improvements and/or phases beyond the Phase I Project.

               4.2.5.4 Notwithstanding the foregoing provisions of this
Article 4 to the contrary, Landlord will not collect or be entitled to collect
Direct Expenses from all of its tenants

                                      -23-
<PAGE>

in an amount which is in excess of one hundred percent (100%) of the Direct
Expenses actually paid by Landlord in connection with the operation of the
Buildings and the Real Property, and Landlord shall make no profit from the
collection of Direct Expenses.

               4.2.5.5 Landlord hereby agrees that in the event that during the
Base Year the cost of any maintenance contract is covered by a warranty and as a
result thereof the cost of such maintenance contract is not included in the Base
Year, the cost of any such maintenance contract shall be added to and included
in the Base Year for purposes of determining the Excess payable for each Expense
Year after the Base Year in which Landlord paid the cost of such maintenance
contract (but at the rate for such maintenance contract which would have been in
effect during the Base Year or the rate in effect during such subsequent Expense
Year, whichever is lower).

          4.2.6 "SYSTEMS AND EQUIPMENT" shall mean any plant, machinery,
transformers, duct work, cable, wires, and other equipment, facilities, and
systems designed to supply heat, ventilation, air conditioning and humidity or
any other services or utilities, or comprising or serving as any component or
portion of the electrical, gas, steam, plumbing, sprinkler, communications,
alarm, security, or fire/life safety systems or equipment, or any other
mechanical, electrical, electronic, computer or other systems or equipment which
serve either or both of the Buildings in whole or in part.

          4.2.7 "TAX EXPENSES" shall mean all federal, state, county, or local
governmental or municipal taxes, fees, charges or other impositions of every
kind and nature, whether general, special, ordinary or extraordinary,
(including, without limitation, real estate taxes, general and special
assessments, transit taxes, leasehold taxes or taxes based upon the receipt of
rent, including gross receipts or sales taxes applicable to the receipt of rent,
unless required to be paid by Tenant, personal property taxes imposed upon the
fixtures, machinery, equipment, apparatus, systems and equipment, appurtenances,
furniture and other personal property used in connection with the Real
Property), which Landlord shall pay during any Expense Year because of or in
connection with the ownership, leasing and operation of the Real Property or
Landlord's interest therein (including any tax expenses, assessments and other
charges allocated to the Real Property under any declaration, restriction
covenant or other instrument pertaining to the sharing of costs by the Real
Property or any portion thereof, including any covenants, conditions or
restrictions now or hereafter recorded against or affecting the Real Property).
For purposes of this Lease, Tax Expenses for the Expense Base Year and each
Expense Year thereafter shall be calculated as if the Buildings, the tenant
improvements therein (at a Building-standard amount) and the Phase I Parking
Structure to be constructed as part of the Phase I Project (as described in the
Tenant Work Letter) were fully constructed and the Phase I Project, the
Buildings, such tenant improvements therein and the Phase I Parking Structure
were fully assessed for real estate tax purposes.

               4.2.7.1 Tax Expenses shall include, without limitation:

                    (i)  any tax on Landlord's rent, right to rent or other
income from the Real Property or as against Landlord's business of leasing any
of the Real Property;

                    (ii) any assessment, tax, fee, levy or charge in addition
to, or in substitution, partially or totally, of any assessment, tax, fee, levy
or charge previously included within the definition of real property tax, it
being acknowledged by Tenant and Landlord that Proposition 13 was adopted by the
voters of the State of California in the June 1978 election ("Proposition 13")
and that assessments, taxes, fees, levies and charges may be imposed by
governmental agencies for such services as fire protection, street, sidewalk and
road maintenance, refuse removal and for other governmental services formerly
provided without charge to property owners or occupants. It is the intention of
Tenant and Landlord that all such new and increased assessments, taxes, fees,
levies, and charges and all similar assessments, taxes, fees, levies and charges
be included within the definition of Tax Expenses for purposes of this Lease;

                    (iii) any assessment, tax, fee, levy, or charge allocable to
or measured by the area of the Premises or the rent payable hereunder,
including, without limitation, any gross income tax upon or with respect to the
possession, leasing, operating,

                                      -24-
<PAGE>

management, maintenance, alteration, repair, use or occupancy by Tenant of the
Premises, or any portion thereof; and

                    (iv) any assessment, tax, fee, levy or charge, upon this
transaction or any document to which Tenant is a party, creating or transferring
an interest or an estate in the Premises.

               4.2.7.2 Landlord shall make such reasonable efforts as Landlord
shall in its reasonable discretion deem reasonably necessary to minimize the
amount of Tax Expenses, including challenging the amount of Tax Expenses with
the applicable governmental authority if Landlord reasonably determines a
reduction in Tax Expenses is likely to result therefrom. Any expenses incurred
by Landlord in attempting to protest, reduce or minimize Tax Expenses shall be
included in Tax Expenses in the Expense Year such expenses are paid but not in
excess of the reduction in Tax Expenses achieved as a result thereof. All tax
refunds pertaining to any Tax Expenses for any particular Expense Year shall be
deducted from Tax Expenses with respect to such Expense Year to which the
reduction relates.

               4.2.7.3 Notwithstanding anything to the contrary contained in
this Section 4.2.7, there shall be excluded from Tax Expenses: (i) all excess
profits taxes, franchise taxes, gift taxes, capital stock taxes, inheritance and
succession taxes, estate taxes, federal and state income taxes, and other taxes
to the extent applicable to Landlord's general or net income (as opposed to
rents, receipts or income attributable to operations at the Real Property); (ii)
any items included as Operating Expenses; (iii) any items paid by Tenant under
Section 4.4 of this Lease; (iv) Tax Expenses attributable to the tenant
improvements of other tenants' or occupants' premises in the Real Property in
excess of the Cut-Off Point, as that term is defined in Section 4.4 below, but
only to the extent such taxes in excess of the Cut-Off Point are directly billed
to and collected from such tenants or occupants; and (v) penalties, interest and
late charges attributable to Landlord's delinquent payment of any Tax Expenses.

          4.2.8 "TENANT'S BUILDING B SHARE" shall mean the percentage set forth
in Section 9.2 of the Summary. Tenant's Building B Share was calculated by
dividing the number of rentable square feet of the portion of the Premises
located in Building B by the total rentable square feet in Building B. Since
Tenant is leasing all of the rentable square feet of Building B, Tenant's
Building B Share equals 100% and shall not be subject to adjustment.

          4.2.9 "TENANT'S BUILDING C SHARE" shall mean the percentage set forth
in Section 9.3 of the Summary. Tenant's Building C Share was calculated by
dividing the number of rentable square feet of the portion of the Premises
located in Building C by the total rentable square feet in Building C. In the
event either the rentable square feet of the portion of the Premises located in
Building C and/or the total rentable square feet of Building C is changed,
Tenant's Building C Share shall be appropriately adjusted, and, as to the
Expense Year in which such change occurs, Tenant's Building C Share for such
year shall be determined on the basis of the number of days during such Expense
Year that each such Tenant's Building C Share was in effect.

          4.2.10 "UTILITIES COSTS" shall mean all actual charges for utilities
for the Buildings and the Project which Landlord shall pay during any Expense
Year, including, but not limited to, the costs of water, sewer and electricity,
and the costs of HVAC and other utilities (but excluding those charges for which
tenants directly reimburse Landlord or pay directly to the utility company) as
well as related fees, assessments and surcharges. Utilities Costs shall be
calculated assuming Building B is at least 100% occupied and Building C (and
during the period of time when any other buildings are fully constructed and
ready for occupancy and are included by Landlord within the Project), is (are)
at least 95% occupied. If, during all or any part of any Expense Year (including
the Base Year), Landlord shall not provide any utilities (the cost of which, if
provided by Landlord, would be included in Utilities Costs) to a tenant
(including Tenant) who has undertaken to provide same instead of Landlord,
Utilities Costs shall be deemed to be increased by an amount equal to the
additional Utilities Costs which would reasonably have been incurred during such
period by Landlord if Landlord had at its own expense provided such utilities to
such tenant. Utilities Costs shall include any costs of utilities which are
allocated to the Real Property under any declaration, restrictive covenant, or
other instrument pertaining to the sharing of costs by the Real Property or any
portion thereof, including any covenants, conditions or restrictions now or
hereafter recorded against or affecting the Real Property. For purposes of
determining Utilities Costs incurred for the Base Year, if there is a
deregulation of

                                      -25-

<PAGE>

the electricity utilities industry during the Base Year, then after calendar
years 2003 and 2004 have occurred and Landlord has determined the electricity
cost component of the Utilities Costs for the Base Year and calendar years 2003
and 2004, the electricity cost component of the Utilities Costs for the Base
Year shall be recalculated to equal the average of the electricity cost
component of the Utilities Costs incurred during the Base Year and calendar
years 2003 and 2004, and based upon such recalculation (which shall be made by
Landlord in the Statement delivered by Landlord pursuant to Section 4.3.2 below
for calendar year 2004), Landlord shall revise the Direct Expenses for the Base
Year. If such recalculation results in an overpayment or underpayment by Tenant
of Direct Expenses for calendar years 2003 and/or 2004, Landlord shall refund to
Tenant or Tenant shall pay to Landlord the amount of overpayment or
underpayment, as the case may be, within thirty (30) days after Landlord's
delivery of the Statement setting forth such recalculation. Notwithstanding the
foregoing to the contrary, Utilities Costs shall not include any penalties,
interest or late charges attributable to Landlord's delinquent payment of any
Utilities Costs.

     4.3  CALCULATION AND PAYMENT OF ADDITIONAL RENT.

          4.3.1 CALCULATION OF EXCESS. If for any Expense Year ending or
commencing within the Lease Term, Tenant's Share of Direct Expenses allocated to
the Buildings pursuant to Section 4.3.4 below for such Expense Year exceeds
Tenant's Share of Direct Expenses allocated to the Buildings for the Base Year,
then Tenant shall pay to Landlord, in the manner set forth in Section 4.3.2,
below, and as additional rent, an amount equal to such excess (the "EXCESS").
For any partial year within the Lease Term, the Excess shall be calculated by
comparing Tenant's Share of Direct Expenses for such partial Expense Year, to
the comparable prorata portion of Tenant's Share of Direct Expenses applicable
to the Base Year.

          4.3.2 STATEMENT OF ACTUAL DIRECT EXPENSES. Following the end of each
Expense Year, Landlord shall give to Tenant a statement (the "STATEMENT") which
shall state the amount of Direct Expenses actually incurred or accrued for that
Expense Year and which shall indicate the amount, if any, of any Excess for that
Expense Year. Such Statement shall be itemized on a line item by line item
basis, showing the Direct Expenses for such Expense Year as well as the Expense
Year immediately prior to such Expense Year. Within thirty (30) days after
Tenant's receipt of the Statement for such preceding Expense Year, if an Excess
is present, Tenant shall pay to Landlord the full amount of the Excess for such
preceding Expense Year, less the amounts, if any, actually paid by Tenant to
Landlord with respect to such preceding Expense Year as "ESTIMATED EXCESS," as
that term is defined in Section 4.3.3 below. If any Statement reflects that the
amount of Estimated Excess paid by Tenant to Landlord for such Expense Year is
greater than the actual amount of the Excess for such Expense Year, then
Landlord shall, at its option, either credit such overpayment toward Tenant's
next rent payment(s) then due and payable under this Lease, or remit such
overpayment to Tenant within thirty (30) days after such applicable Statement is
delivered to Tenant. Even though the Lease Term has expired and Tenant has
vacated the Premises, if the Statement for the Expense Year in which this Lease
terminates reflects that Tenant's payment to Landlord of Estimated Excess for
such Expense Year was greater than or less than the actual amount of Excess for
such last Expense Year, then within thirty (30) days after Landlord's delivery
of such Statement to Tenant, Landlord shall refund to Tenant any such
overpayment, or Tenant shall pay to Landlord any such underpayment, as the case
may be. Landlord shall endeavor to deliver the applicable Statement to Tenant
within one hundred twenty (120) days after the end of the Expense Year in
question, but the failure of Landlord to furnish such Statement within such 120
day period shall not prejudice Landlord from enforcing its rights under this
Article 4; provided, however, Landlord's failure to provide Tenant with a
Statement for a particular Expense Year within two (2) years after the end of
the Expense Year in question, shall constitute a waiver of Landlord's right to
collect any Excess payable for such Expense Year; provided further, however,
that such limitation on Landlord's ability to collect any Excess as a result of
any late delivery of such Statement shall not preclude Landlord from modifying
any Statement once such Statement is timely delivered, as provided hereinabove,
to correct any errors or reflect any new information received by Landlord with
respect to the Direct Expenses shown on such Statement (including, without
limitation, as a result of any new or supplemental tax bills issued by the
applicable taxing authority or any audit conducted by Tenant or any other tenant
of the Real Property), so long as Landlord delivers such revised Statement to
Tenant within two (2) years after Landlord becomes aware of such errors or
receives such new information. In the event that any such revised Statement so
delivered shows that an additional Excess is present, then Tenant shall pay to
Landlord, within thirty (30) days of receipt of the revised Statement, the
amount of the


                                      -26-
<PAGE>

additional Excess. If any such revised Statement reflects that Tenant has
overpaid Tenant's Share of Direct Expenses for such Expense Year, Landlord
shall, at its option either credit such overpayment toward Tenant's next rent
payment(s) under this Lease, or refund the overpayment to Tenant within thirty
(30) days after such applicable revised Statement is delivered to Tenant. The
provisions of this Section 4.3.2 shall survive the expiration or earlier
termination of the Lease Term for a period of two (2) years thereafter, but
without derogating from the 2-year limitation set forth hereinabove.

          4.3.3 STATEMENT OF ESTIMATED DIRECT EXPENSES. Prior to that date which
is thirty (30) days prior to the first day of a new Expense Year, Landlord shall
endeavor to give Tenant a yearly expense estimate statement (the "ESTIMATE
STATEMENT") which shall set forth Landlord's reasonable estimate (the
"Estimate") of what the total amount of Direct Expenses allocated to the
Buildings pursuant to Section 4.3.4 below for the new Expense Year shall be and
the estimated Excess (the "ESTIMATED EXCESS"), as calculated by comparing
Tenant's Share of Direct Expenses allocated to the Buildings, which shall be
based upon the Estimate, to Tenant's Share of Direct Expenses allocated to the
Buildings for the Base Year. Such Statement shall be itemized on a line item by
line item basis, showing the estimated Direct Expenses for such new Expense Year
as well as the estimated Direct Expenses for the Expense Year immediately prior
to such new Expense Year. The failure of Landlord to timely furnish the Estimate
Statement for any Expense Year shall not preclude Landlord from enforcing its
rights under this Article 4. Tenant shall pay to Landlord the Estimated Excess
for each such Expense Year, in monthly installments of one-twelfth (1/12)
thereof on the first day of each calendar month during such Expense Year;
provided, however, if such Estimate Statement is delivered to Tenant after the
start of such new Expense Year, Tenant shall pay to Landlord, with its next
installment of Base Rent due, a fraction of the Estimated Excess for the
then-current Expense Year (reduced by any amounts paid pursuant to the last
sentence of this Section 4.3.3). Such fraction shall have as its numerator the
number of months which have elapsed in such current Expense Year to the month of
such payment, both months inclusive, and shall have twelve (12) as its
denominator. If at any time Landlord determines that the Excess for an Expense
Year is projected to vary from the then Estimated Excess for such Expense Year,
Landlord may, by notice to Tenant, revise such Estimated Excess, and Tenant's
monthly installments for the remainder of such Expense Year shall be adjusted so
that by the end of such Expense Year Tenant shall have paid to Landlord the
revised Estimated Excess for such Expense Year. Until a new Estimate Statement
is furnished, Tenant shall pay monthly, with the monthly Base Rent installments,
an amount equal to one-twelfth (1/12) of the Estimated Excess set forth in the
previous Estimate Statement delivered by Landlord to Tenant.

          4.3.4 ALLOCATION OF DIRECT EXPENSES TO THE BUILDINGS. The parties
acknowledge that when constructed the Buildings will be part of a multi-building
project consisting of the Buildings, the Existing Buildings, and such other
buildings as Landlord may elect to construct and include as part of the Project
from time to time (collectively, the "OTHER BUILDINGS"), and that certain of the
costs and expenses incurred in connection with the Real Property (i.e., certain
of the Direct Expenses) shall be shared among the Existing Buildings, the
Buildings and such Other Buildings, while certain other costs and expenses which
are solely attributable or exclusively pertaining to the Buildings, the Existing
Buildings and/or such Other Buildings, as applicable, shall be allocated
directly to the Buildings, Existing Buildings and/or such Other Buildings,
respectively. Accordingly, as set forth in Sections 4.1 and 4.2 above, Direct
Expenses are determined annually for the Real Property as a whole, and a portion
of the Direct Expenses, which portion shall be reasonably determined by Landlord
on an equitable basis, shall be allocated to the Buildings (as opposed to the
Existing Buildings and any such Other Buildings), and such portion so allocated
shall be the amount of Direct Expenses payable with respect to the Buildings
upon which the applicable Tenant's Share shall be calculated. Such portion of
the Direct Expenses allocated to the Buildings and payable by Tenant hereunder
shall include all Direct Expenses which are attributable solely to the
Buildings, and an equitable portion of the Direct Expenses attributable to the
Real Property as a whole. In addition, as a further allocation of those Direct
Expenses allocated to the Buildings, Landlord shall allocate to Building B,
separately, those Direct Expenses, if any, which have been so allocated to the
Buildings but which are solely attributable to Building B (and not Building C),
and Landlord shall allocate to Building C, separately, those Direct Expenses, if
any, which have been so allocated to the Buildings but which are solely
attributable to Building C (and not Building B). As an example of such
allocation of Direct Expenses it is anticipated that Landlord may receive
separate tax bills which separately assess the improvements component of Tax
Expenses for each

                                      -27-
<PAGE>

office building in the Project, and/or Landlord may receive separate utilities
bills from the utilities companies identifying the Utilities Costs for certain
of the utilities costs directly incurred by each such office building (as
measured by separate meters installed for such building), and such separately
assessed Tax Expenses and separately metered Utilities Costs shall be calculated
for and allocated separately to each such applicable office building. In
addition, in the event Landlord elects, at its sole option, to subdivide certain
common area portions of the Real Property such as landscaping, public and
private streets, driveways, walkways, courtyards, plazas, transportation
facilitation areas, accessways and/or parking areas into a separate parcel or
parcels of land (and/or separately convey all or any of such parcels to a common
area association to own, operate and/or maintain same), the Direct Expenses for
such common area parcels of land should be aggregated and then reasonably
allocated by Landlord to the Buildings, Existing Buildings and such Other
Buildings on an equitable basis as Landlord (and/or any applicable covenants,
conditions and restrictions for any such common area association) shall provide
from time to time.

          4.3.5 PAYMENT IN INSTALLMENTS. All assessments and premiums which are
not specifically charged to Tenant because of what Tenant has done, which can be
paid by Landlord in installments without the imposition of fees, penalties or
interest, shall be paid by Landlord in the maximum number of installments that
are permitted by law without the imposition of fees, penalties or interest and
not included as Direct Expenses except in the Expense Year in which the
assessment or premium installment is actually paid; provided, however, that if
the prevailing practice in Comparable Buildings is to pay such assessments or
premiums on an earlier basis, and Landlord pays on such earlier basis, such
assessments or premiums shall be included in Direct Expenses as paid by
Landlord.

     4.4  TAXES AND OTHER CHARGES FOR WHICH TENANT IS DIRECTLY RESPONSIBLE.
Tenant shall reimburse Landlord within thirty (30) days after demand for any and
all taxes or assessments required to be paid by Landlord (except to the extent
included in Tax Expenses by Landlord), excluding state, local and federal
personal or corporate income taxes measured by the net income of Landlord from
all sources and estate and inheritance taxes, whether or not now customary or
within the contemplation of the parties hereto, when:

          (i)  said taxes are measured by or reasonably attributable to the cost
or value of Tenant's equipment, furniture, fixtures and other personal property
located in the Premises, or by the cost or value of any leasehold improvements
made in or to the Premises by or for Tenant, to the extent the cost or value of
such leasehold improvements exceeds the amount per square foot which Landlord
uses as a base value above which Landlord charges other tenants of the Real
Property for real estate taxes attributable to the cost or value of leasehold
improvements located in such tenants' premises (the "CUT-OFF POINT");

          (ii) said taxes are assessed upon or with respect to the possession,
leasing, operation, management, maintenance, alteration, repair, use or
occupancy by Tenant of the Premises or any portion of the Real Property
(including the Parking Facilities); or

          (iii) said taxes are assessed upon this transaction or any document to
which Tenant is a party creating or transferring an interest or an estate in the
Premises.

     4.5  LATE CHARGES. If any installment of Rent or any other sum due from
Tenant shall not be received by Landlord or Landlord's designee within five (5)
business days after written notice from Landlord that said amount is past due,
then Tenant shall pay to Landlord a late charge equal to five percent (5%) of
the amount due or in the case of a delinquent installment of Base Rent, two
percent (2%) of the delinquent amount; provided, however, that if Landlord has
given Tenant two (2) such delinquency notices in the preceding twelve (12) month
period, then the late charge shall be imposed for any subsequent delinquent
payment of Rent by Tenant, without requirement of any notice or cure period. The
late charge shall be deemed Additional Rent and the right to require it shall be
in addition to all of Landlord's other rights and remedies hereunder or at law
and shall not be construed as liquidated damages or as limiting Landlord's
remedies in any manner. In addition to the late charge described above, any Rent
or other amounts owing hereunder which are not paid within five (5) business
days after written notice from Landlord that said amount is past due shall bear
interest from the date due until paid at a rate (the "INTEREST RATE") equal to
the lower of (i) the then-current prime interest rate as such rate is announced
by The Wall Street Journal plus two (2) percentage points, or (ii) the highest
rate permitted by applicable law; provided, however, that if Landlord has given
Tenant two

                                      -28-
<PAGE>

(2) such delinquency notices in the preceding twelve (12) month period, then
interest shall be imposed for any subsequent delinquent payment of Rent by
Tenant, without requirement of any notice or cure period.

     4.6  BOOKS AND RECORDS. Landlord shall maintain in a safe and orderly
manner books and records, or make available such books and records, in Los
Angeles and/or Orange Counties in accordance with sound accounting and
management practices, reflecting the Direct Expenses. Landlord shall maintain
such books and records for the Direct Expenses for each Expense Year for the
entirety of the period which ends two (2) years following Landlord's delivery to
Tenant of each such Statement, except that Landlord shall maintain such books
and records with respect to each applicable Base Year during the entire Lease
Term plus two (2) years after the expiration or sooner termination of the Lease
Term.

     4.7  AUDIT RIGHTS. In the event Tenant disputes the amount of the Direct
Expenses set forth in the Statement for the particular Expense Year delivered by
Landlord to Tenant pursuant to Section 4.3.2 above, Tenant shall have the right,
at Tenant's cost, after reasonable notice to Landlord, to have Tenant's
authorized employees inspect, at Landlord's office in Los Angeles and/or Orange
Counties during normal business hours, Landlord's books, records and supporting
documents concerning the Direct Expenses set forth in such Statement; provided,
however, Tenant shall have no right to conduct such inspection, have an audit
performed by the Accountant as described below, or object to or otherwise
dispute the amount of the Direct Expenses set forth in any such Statement unless
Tenant notifies Landlord of such objection and dispute, completes such
inspection, and has the Accountant commence and complete such audit within two
(2) years immediately following Landlord's delivery of the particular Statement
in question (the "REVIEW PERIOD"); provided, further, that notwithstanding any
such timely objection, dispute, inspection, and/or audit, and as a condition
precedent to Tenant's exercise of its right of objection, dispute, inspection
and/or audit as set forth in this Section 4.7, Tenant shall not be permitted to
withhold payment of, and Tenant shall timely pay to Landlord, the full amounts
as required by the provisions of this Article 4 in accordance with such
Statement. However, such payment may be made under protest pending the outcome
of any audit which may be performed by the Accountant as described below. In
connection with any such inspection by Tenant, Landlord and Tenant shall
reasonably cooperate with each other so that such inspection can be performed
pursuant to a mutually acceptable schedule, in an expeditious manner and without
undue interference with Landlord's operation and management of the Real
Property. If after such inspection and/or request for documentation, Tenant
still disputes the amount of the Direct Expenses set forth in the Statement,
Tenant shall have the right, within the Review Period, to cause an independent
certified public accountant (which is not paid on a commission or contingency
basis) selected by Tenant and reasonably approved by Landlord (the "ACCOUNTANT")
to complete an audit of Landlord's books and records to determine the proper
amount of the Direct Expenses incurred and amounts payable by Tenant for the
Expense Year which is the subject of such Statement. Such audit by the
Accountant shall be final and binding upon Landlord and Tenant. If Landlord and
Tenant cannot mutually agree as to the identity of the Accountant within thirty
(30) days after Tenant notifies Landlord that Tenant desires an audit to be
performed, then the Accountant shall be of the "BIG 5" accounting firms (which
is not paid on a commission or contingency basis), as selected by Tenant and
reasonably approved by Landlord. If such audit reveals that Landlord has
over-charged Tenant, then within thirty (30) days after the results of such
audit are made available to Landlord, Landlord shall reimburse to Tenant the
amount of such over-charge, together with interest on the amount of the
over-charge at the Interest Rate (as defined in Section 4.5 above). If the audit
reveals that the Tenant was under-charged, then within thirty (30) days after
the results of such audit are made available to Tenant, Tenant shall reimburse
to Landlord the amount of such under-charge. Tenant agrees to pay the cost of
such audit unless it is subsequently determined that Landlord's original
Statement which was the subject of such audit overstated Direct Expenses by four
percent (4%) or more of the actual Direct Expenses which was the subject of such
audit. The payment by Tenant of any amounts pursuant to this Article 4 shall not
preclude Tenant from questioning, during the Review Period, the correctness of
the particular Statement in question provided by Landlord, but the failure of
Tenant to object thereto, conduct and complete its inspection and have the
Accountant conduct the audit as described above prior to the expiration of the
Review Period for such Statement shall be conclusively deemed Tenant's approval
of the Statement in question and the amount of Direct Expenses shown thereon. If
following Tenant's delivery to Landlord of a written request to make Landlord's
books and records regarding the Direct Expenses reasonably available to Tenant
and/or the Accountant to conduct any such inspection and/or audit described

                                      -29-
<PAGE>

above in this Section 4.7, Landlord fails to make Landlord's books reasonably
available for such purposes during Landlord's normal business hours, and such
failure continues for one (1) business day after Tenant notifies Landlord
thereof, then the Review Period shall be extended one (1) day for each such day
that Tenant and/or the Accountant, as the case may be, is so prevented from
accessing such books and records. In connection with any inspection and/or audit
conducted by Tenant pursuant to this Section 4.7, Tenant agrees to keep, and to
cause all of Tenant's employees and consultants and the Accountant to keep, all
of Landlord's books and records and the audit, and all information pertaining
thereto and the results thereof, strictly confidential (except if required by
any court to disclose such information or if such information is available from
an inspection of public records), and in connection therewith, Tenant shall
cause such employees, consultants and the Accountant to execute such reasonable
confidentiality agreements as Landlord may require prior to conducting any such
inspections and/or audits.

                                    ARTICLE 5

                                 USE OF PREMISES

     5.1  USE. Tenant shall use the Premises solely for general office and
administrative purposes consistent with the character of the Real Property as a
first-class, multi-tenant office building project, and Tenant shall not use or
permit the Premises to be used for any other purpose or purposes whatsoever.
Tenant further covenants and agrees that it shall not use, or suffer or permit
any person or persons to use, the Premises or any part thereof for any use or
purpose contrary to the provisions of EXHIBIT D, attached hereto, or in
violation of applicable Laws (as defined in Article 22 below). Tenant shall
comply with all recorded covenants, conditions and restrictions, and the
provisions of all ground or underlying leases, now or hereafter affecting the
Real Property (including, without limitation, that certain proposed Agreement
and Declaration of Covenants, Conditions and Restrictions for LNR Warner Center
(the "PROPOSED CC&R'S") [a draft copy of the latest version of which dated
September 13, 2000 has been provided to Tenant], in its final form as and when
recorded against the Real Property, and as thereafter amended from time to
time), so long as the same (including any actions undertaken by Landlord
thereunder as "Declarant", and/or any amendments thereto unilaterally effected
by Landlord as "Declarant" thereunder) (i) do not materially derogate from the
rights of Tenant under this Lease, including, without limitation, the rights
granted to Tenant pursuant to Sections 21.5 and 25.30 below, or (ii) result in
an assessment of any additional material monetary obligations directly upon
Tenant (as opposed to a pass-through of Direct Expenses described in Article 4
above). In connection with Tenant's compliance obligations under any such Laws
and/or such recorded covenants, conditions and restrictions, and to the extent
expressly required thereunder, Tenant agrees to: (A) develop an active recycling
program to reduce solid waste, and participate in any such recycling program
developed by Landlord or any common area association with or under in such
covenants, conditions and restrictions, and/or developed by any local
municipalities or governmental agencies having jurisdiction over the Real
Property; (B) use reasonable efforts to cooperate in and comply with programs
which may be undertaken by Landlord independently, or in cooperation with local
municipalities or governmental agencies or other property owners in the vicinity
of LNR Warner Center, to reduce peak levels of commuter traffic; such programs
may include, but shall not be limited to, carpools, vanpools and other ride
sharing programs, public and private transit, and flexible work hours; (C) to
the extent any such traffic mitigation programs are deemed mandatory by such
local municipalities or government agencies, to comply with such programs
(including any programs implemented by Landlord or any common area association
under any covenants, conditions and restrictions recorded against the Real
Property); and (D) in connection with Tenant's obligations under clauses (B) and
(C) hereinabove, Tenant agrees to appoint one of its employees to act as a
liaison to the transportation coordinators in any buildings in the Real Property
occupied or leased by Tenant. Landlord covenants and represents to Tenant that:
(1) Tenant's use of the Premises for general office and administrative purposes
is permitted under the Proposed CC&R's and will be permitted under any recorded
covenants, conditions and restrictions and the provisions of all ground or
underlying leases now or hereafter affecting the Real Property (collectively,
the "RECORDED DOCUMENTS"); (2) to the extent Tenant is required to obtain
approvals under any such Recorded Documents to have the full benefit of all
rights specifically provided to Tenant under this Lease (including with respect
to Tenant's signage rights in Section 21.5 and Tenant's Telecommunication
Equipment in Section 25.30) and Tenant must seek such approvals through Landlord
as owner of the Real Property because Tenant has no standing under any such
Recorded Documents to directly obtain such approvals on its own behalf, Landlord
shall use reasonable efforts (subject to Tenant reimbursing Landlord or

                                      -30-
<PAGE>

paying directly for any reasonable out-of-pocket costs incurred by Landlord) to
seek such approvals on Tenant's behalf to the extent not inconsistent with
Landlord's rights or any other provisions of this Lease; and (3) the
indemnification obligations contained in Section 3.4 of the Proposed CC&R's (or
the version thereof recorded against the Real Property), and any amendments
thereto to shall not apply to Tenant.

     5.2  HAZARDOUS MATERIALS. Tenant shall not use or allow another person or
entity to use any part of the Premises for the storage, use, treatment,
manufacture or sale of Hazardous Material (as defined in Section 1.3 above).
Landlord acknowledges, however, that Tenant will maintain products in the
Premises which are incidental to the operation of its general office use,
including, without limitation, photocopy supplies, secretarial supplies and
limited janitorial supplies, which products contain chemicals which are
categorized as Hazardous Materials. Landlord agrees that the use of such
products in the Premises in the manner in which such products are designed to be
used and in compliance with applicable laws shall not be a violation by Tenant
of this Article 5.

                                    ARTICLE 6

                             SERVICES AND UTILITIES

     6.1  STANDARD TENANT SERVICES. Landlord shall provide the following
services on all days during the Lease Term in a first-class manner, unless
otherwise stated below. Unless otherwise provided below, Landlord shall manage
the Buildings and such services shall be supplied in a first-class manner
consistent with other Comparable Buildings.

          6.1.1 Subject to reasonable changes implemented by Landlord (which,
with respect to such changes Landlord may desire to implement for Building B
only, Tenant shall have the right to reasonably approve same in advance of their
implementation) and to all governmental rules, regulations and guidelines
applicable thereto, Landlord shall provide HVAC for normal office use in the
Premises during the Business Hours (as defined below) so as to maintain
temperatures within the Premises within the range of temperatures that are
consistent with the design capacity of the HVAC system installed by Landlord as
part of the Base, Shell and Core as specified in EXHIBIT L attached to this
Lease, subject to extraordinary hot or cold weather periods, unusual heat loads
caused by Tenant's use of the Premises, any use of the Premises for other than
general office use, brown-outs and/or other Force Majeure events. As used
herein, the "BUSINESS HOURS" shall mean 8:00 a.m. to 6:00 p.m. Monday through
Friday, and 9:00 a.m. to 1:00 p.m. on Saturday, except for the date of
observation of New Year's Day, Presidents' Day, Memorial Day, Independence Day,
Labor Day, Thanksgiving Day and Christmas Day (collectively, the "HOLIDAYS");
provided, however, that with respect to Tenant's use of HVAC in Building B,
Landlord shall change the Business Hours for Building B, only, to any other
hours requested by Tenant so long as (i) Landlord is reasonably able to make
such change, (ii) Tenant gives Landlord at least thirty (30) days' advance
written notice of such requested change, (iii) Tenant's request does not exceed
fifty-five (55) hours per week, (iv) Landlord shall not be obligated to cause
the Building's HVAC system to maintain the temperatures within the ranges set
forth hereinabove during any such hours which are not the original Business
Hours specified hereinabove, unless Tenant is compensating Landlord for
non-Business Hours usage pursuant to Section 6.2 below and then only with
respect to the areas within the Premises for which Tenant is so compensating
Landlord for such non-Business Hours usage (but subject to any start-up period
of time for such areas to reach a stabilized temperature range), and (v) Tenant
pays for any increased cost of providing HVAC during any such changed hours as
compared to the cost which would reasonably have been incurred in providing such
HVAC during the original Business Hours prior to such change (for example, in
the summer, if HVAC is only provided to the Premises during a non-Holiday
weekday for 10 consecutive hours, it is anticipated that the cost to provide
such HVAC during the 10-hour period from 8:00 a.m. to 6:00 p.m. on such day will
be substantially less expensive than providing HVAC during the 10-hour period
from 10:00 a.m. to 8:00 p.m. on the same day due to, for example, higher rates
and warmer temperatures in effect during the latter 10-hour period).

          6.1.2 Landlord shall provide adequate electrical wiring and facilities
and power for normal general office use as reasonably determined by Landlord.
Upon request, Landlord shall replace lamps, starters and ballasts for Building
standard lighting fixtures (with Building standards to be determined based upon
the standard tenant improvement Specifications, as defined in the Tenant Work
Letter, for lighting fixtures in Building C), the cost of which shall

                                      -31-
<PAGE>

be included in Operating Expenses. Tenant shall bear the cost of replacement of
all lamps, starters and ballasts for non-Building standard lighting fixtures
within the Premises.

          6.1.3 Landlord shall provide city water from the regular building
outlets for drinking, lavatory and toilet purposes for normal office use, and
for use in kitchen and other eating areas within the Premises for normal office
use.

          6.1.4 Landlord shall provide (i) janitorial services five (5) days per
week, except the date of observation of the Holidays, in and about the Premises
and (ii) window washing services, all in accordance with the janitorial and
window washing specifications attached hereto as EXHIBIT K (which are subject to
change provided that the overall level of the janitorial and window washing
services provided by Landlord is not reduced below the level set forth in the
specifications attached as EXHIBIT K or below the level provided at Comparable
Buildings).

          6.1.5 Landlord shall provide nonexclusive automatic passenger elevator
service at all times; provided, however, while Tenant is leasing the entire
rentable area of Building B as part of the Premises under this Lease such
passenger elevator service within Building B shall be exclusive, except that
Landlord and its employees, agents and contractors shall have the right to use
such elevators for purposes reasonably related to the performance of Landlord's
obligations and exercise of Landlord's rights under this Lease without
unreasonable interference with Tenant's permitted use of the Premises.

     6.2  OVERSTANDARD TENANT USE. Tenant shall not, without Landlord's prior
written consent, (i) use heat-generating machines, machines other than normal
fractional horsepower office machines, or equipment or lighting other than
building standard lights in the Premises, which may affect the temperature
otherwise maintained by the air conditioning system, or (ii) increase the water
normally furnished for the normal office use for the Premises by Landlord
pursuant to the terms of Section 6.1.3 above. In addition, Tenant shall not use
electricity in the Premises in excess of the capacity of the electricity feeders
and risers serving the Premises. If Tenant uses water or HVAC in excess of the
quantities to be provided by Landlord for normal office use pursuant to Section
6.1 above, or if Tenant's consumption of electricity shall exceed five (5) watts
per usable square foot of the Premises for connected electrical load of 120/208
voltage power equipment and one and one half (1 1/2) watts per usable square
foot of the Premises for connected electrical load for 277/480 voltage power
equipment, calculated on an average annualized basis for Business Hours
described in Section 6.1.1 above, then Tenant shall pay to Landlord, within
thirty (30) days after billing, the sum of (A) the actual cost of such excess
consumption plus a five percent (5%) surcharge on such costs to cover Landlord's
administrative costs, plus (B) the cost of the installation, operation, and
maintenance of equipment which is installed in order to supply such excess
consumption, plus (C) the cost of the increased wear and tear and depreciation
on existing equipment caused by such excess consumption; Landlord may reasonably
install devices to separately meter any such excess use, and in such event
Tenant shall pay to Landlord the cost of such additional metering devices within
thirty (30) days after demand therefor. If Tenant desires to use HVAC in the
Premises during hours other than the Business Hours pursuant to the terms of
Section 6.1.1 above: (x) Tenant shall give Landlord such prior notice, as
Landlord shall from time to time establish as appropriate (which notice is
anticipated to be accomplished through telephonic dial-up and access via
computer codes), of Tenant's desired use thereof; (y) Landlord shall supply such
after-hours HVAC to Tenant at such hourly cost to Tenant as Landlord shall from
time to time establish; such hourly cost shall be determined on a per floor
basis and shall equal the actual cost incurred by Landlord to supply such
after-hours HVAC on an hourly basis, including (1) the cost of the utilities
consumption plus a five percent (5%) surcharge on such costs to cover Landlord's
administrative costs, (2) increased wear and tear and depreciation on equipment
to provide such after-hours HVAC, and (3) maintenance costs; and (z) Tenant
shall pay such cost to Landlord as Additional Rent within thirty (30) days after
billing.

     6.3  INTERRUPTION OF USE. Subject to Landlord's indemnity of Tenant in
Section 10.1.2 below and subject to the abatement provisions in Section 6.5
below, Tenant agrees that Landlord shall not be liable for damages, by abatement
of Rent or otherwise, for failure to furnish or delay in furnishing any service
(including telephone and telecommunication services), or for any diminution in
the quality or quantity thereof, when such failure or delay or diminution is
occasioned, in whole or in part, by repairs, replacements, or improvements, by
any strike, lockout or other labor trouble, by inability to secure electricity,
gas, water, or other fuel at the

                                      -32-
<PAGE>

Buildings or Real Property, by any accident or casualty whatsoever, by act or
default of Tenant or other parties, or by any other cause; and such failures or
delays or diminution shall never be deemed to constitute an eviction or
disturbance of Tenant's use and possession of the Premises or relieve Tenant
from paying Rent (except as provided in Section 6.5 below) or performing any of
its obligations under this Lease. Furthermore, except as expressly provided in
Section 10.1 below, Landlord shall not be liable under any circumstances for a
loss of, or injury to, property or for injury to, or interference with, Tenant's
business, including, without limitation, loss of profits, however occurring,
through or in connection with or incidental to a failure to furnish any of the
services or utilities as set forth in this Article 6.

     6.4  ADDITIONAL SERVICES. Provided that Landlord can provide such services
(i) at a competitive price, (ii) at a comparable level of quality and (iii)
within a comparable period of time (as compared to third party providers of such
services to Comparable Buildings), Landlord shall also have the exclusive right,
but not the obligation, to provide any additional services which may be required
by Tenant, including, without limitation, locksmithing, lamp replacement,
additional janitorial service, and additional repairs and maintenance, provided
that Tenant shall pay to Landlord within thirty (30) days after billing, the sum
of all costs to Landlord of such additional services plus an administration fee
equal to five percent (5%) of such costs. Charges for any service for which
Tenant is required to pay from time to time hereunder shall be deemed Additional
Rent hereunder, and shall be billed on a monthly basis. In the event that
Landlord fails to meet any of the three (3) criteria set forth in the first
clause of the first sentence of this Section 6.4, then Tenant shall have the
right to select a third party which provides such services to Comparable
Buildings, subject to Landlord's reasonable approval.

     6.5  ABATEMENT OF RENT WHEN TENANT IS PREVENTED FROM USING PREMISES. In the
event that Tenant is actually prevented from using, and does not use, the
Premises or any portion thereof, for five (5) consecutive business days or
fifteen (15) business days in any consecutive 12-month period (the "ELIGIBILITY
PERIOD") as a result of (i) any construction, repair, maintenance or alteration
performed by Landlord after the Lease Commencement Date, (ii) any failure to
provide to the Premises any of the essential utilities and services required to
be provided in Sections 6.1.1 or 6.1.2 above, (iii) any failure to provide
access to the Premises, (iv) any failure by Landlord to perform Landlord's
repair obligations under Section 7.2 below prior to the expiration of the
Outside Repair Period (as defined in Section 7.3 below), (v) any entry onto the
Premises by Landlord pursuant to Article 23 below, or (vi) because of the
presence of Hazardous Materials in, on or around the Building, the Premises or
the Real Property which were not caused or introduced by Tenant or Tenant's
agents, employees, licensees or invitees, and which Hazardous Materials pose a
material and significant health risk to occupants of the Premises as determined
by applicable governmental authorities pursuant to applicable Environmental Laws
by written notice delivered to Landlord and Tenant, which notice specifically
prohibits occupancy of the Premises (or portions thereof) as a result of such
Hazardous Materials, then Tenant's obligation to pay Base Rent and Tenant's
Share of increases in Direct Expenses shall be abated or reduced, as the case
may be, from and after the first (1st) day following the Eligibility Period and
continuing until such time that Tenant continues to be so prevented from using,
and does not use, the Premises or a portion thereof, in the proportion that the
rentable square feet of the portion of the Premises that Tenant is prevented
from using, and does not use, bears to the total rentable square feet of the
Premises. If Tenant's right to rent abatement pursuant to this Section 6.5
occurs during a free rent period which arises after the Lease Commencement Date,
Tenant's free rent period shall be extended for the number of days that the
abatement period overlapped the free rent period (the "OVERLAP PERIOD"), and
Landlord shall have the right to extend the Lease Expiration Date for a period
of time equal to the Overlap Period if Landlord notifies Tenant of such election
in writing within thirty (30) days after the end of the extended free rent
period. To the extent Tenant shall be entitled to abatement of rent because of a
damage or destruction pursuant to Article 11 or a taking pursuant to Article 13,
then the Eligibility Period shall not be applicable.

     6.6  ACCESS TO PREMISES. Subject to all of the terms and conditions of this
Lease, including the Rules and Regulations attached hereto as EXHIBIT D, and all
applicable Laws, Tenant shall have access to the Premises twenty-four (24) hours
per day, seven (7) days per week.

                                     REPAIRS

     7.1  TENANT'S REPAIRS. Subject to Landlord's repair obligations in
Section 7.2 and to the provisions of Articles 11 and 13 below, Tenant shall, at
Tenant's own expense, keep the Premises and all portions thereof, including all
improvements, fixtures, equipment and furnishings therein (including, without
limitation, all non-Base, Shell and Core systems and equipment within the
Premises, including all components and equipment and systems providing
distribution from the Base, Shell and Core systems and equipment), in good
order, repair and condition at all times during the Lease Term, except for
ordinary wear and tear and casualty damage which is not specifically made the
responsibility of Tenant under this Lease. In connection with such repair
obligations, Tenant shall, at Tenant's own expense but subject to the prior
approval of Landlord (which approval shall not be unreasonably withheld or
delayed), and within any reasonable period of time specified by Landlord,
promptly and adequately repair all damage to the Premises and replace or repair
all damaged or broken fixtures and appurtenances; provided however, that, at
Landlord's option, or if Tenant fails to make such repairs within a reasonable
period of time and after Landlord has notified Tenant of its intention to do so,
Landlord may, but need not, make such repairs and replacements, and Tenant shall
pay to Landlord, within thirty (30) days after invoice, the actual, reasonable
and documented costs thereof, plus an administration fee equal to five percent
(5%) of such costs. Landlord may, but shall not be required to, enter the
Premises at all reasonable times, and upon reasonable prior notice to Tenant (or
without notice in case of emergency), to make such repairs, alterations,
improvements and additions to the Premises or to the Buildings or to any
equipment located in the Buildings as shall be necessary or desirable in
connection with the first-class management and operation standards for the
Buildings set forth herein, and/or as may be required for Landlord to comply
with the provisions of this Lease and/or as may be required by applicable laws
and/or governmental or quasi-governmental authority or court order or decree.
Landlord shall use commercially reasonable efforts to minimize interference with
Tenant's use of and access to the Premises during Landlord's entry into the
Premises to perform such work pursuant to the foregoing provisions of this
Section 7.1.

     7.2  LANDLORD'S REPAIRS. Anything contained in Section 7.1 above to the
contrary notwithstanding, subject to Articles 11 and 13 below, at all times
during the Lease Term Landlord shall repair and maintain (including
replacements) in good order, condition and repair and in a manner generally
consistent with the maintenance and repair (including replacements) standards of
Comparable Buildings, the structural portions of the Buildings, the exterior
windows of the Buildings, the roof of each Building, the Base, Shell and Core
components of the Buildings (including the restrooms originally installed as
part of the Base, Shell and Core) and the common areas of Building C (and the
common areas of the Real Property until such time as such repair and maintenance
obligations therefor are made the obligation of any common area association);
provided, however, to the extent such Landlord-required maintenance and repairs
are required to be performed as a result of the act, neglect, fault of or
omission of any duty by Tenant, its agents, employees or invitees, Tenant shall
pay to Landlord as additional rent, the reasonable cost of such maintenance and
repairs (but only to the extent such cost is not covered by Landlord's insurance
obtained pursuant to Section 10.2 of this Lease). Subject to Landlord's
indemnity of Tenant in Section 10.1.2 below and subject to the abatement
provisions in Section 6.5 above, there shall be no abatement of rent and no
liability of Landlord (including any liability for any injury to or interference
with Tenant's business) arising from the making of or failure to make any
repairs, alterations or improvements in or to any portion of the Real Property,
the Buildings or the Premises or in or to fixtures, appurtenances and equipment
therein. Subject to Section 7.3 below, Tenant hereby waives and releases its
right to make repairs at Landlord's expense under Sections 1941 and 1942 of the
California Civil Code, or under any similar law, statute, or ordinance now or
hereafter in effect.

     7.3  TENANT'S SELF-HELP RIGHTS. Notwithstanding anything to the contrary
set forth in this Article 7, if Tenant provides written notice to Landlord of
the need for repairs and/or maintenance which are Landlord's obligation to
perform under the terms of this Lease, and Landlord fails to undertake such
repairs and/or maintenance within a reasonable period of time, given the
circumstances, after receipt of such notice, but in any event not later than
thirty (30) days after receipt of such notice (or such longer time as is
reasonably necessary if more than thirty (30) days are reasonably required to
complete such repairs and Landlord commences such repairs within such 30-day
period and thereafter diligently attempts to complete same), then

                                      -34-
<PAGE>

Tenant may proceed to undertake such repairs and/or maintenance upon delivery of
an additional five (5) days' notice (or an additional two (2) business days,
notice in the event of emergency) to Landlord that Tenant is taking such
required action. If such repairs and/or maintenance were required under the
terms of this Lease to be performed by Landlord and are not performed by
Landlord prior to the expiration of such 5-day period or 2-day period, as the
case may be (the "OUTSIDE REPAIR PERIOD"), then Tenant shall be entitled to
reimbursement by Landlord of Tenant's actual, reasonable, and documented costs
and expenses in performing such maintenance and/or repairs. Such reimbursement
shall be made within thirty (30) days after Landlord's receipt of invoice of
such costs and expenses, and if Landlord fails to so reimburse Tenant within
such 30-day period, then Tenant shall be entitled to offset against the Rent
payable by Tenant under this Lease the amount of such invoice together with
interest thereon, at the Interest Rate, which shall have accrued on the amount
of such invoice during the period from and after Tenant's delivery of such
invoice to Landlord through and including the earlier of the date Landlord
delivers the payment to Tenant or the date Tenant offsets such amount against
the Rent; provided, however, that notwithstanding the foregoing to the contrary,
if (i) Landlord delivers to Tenant prior to the expiration of the applicable
Outside Repair Period described above, a written objection to Tenant's right to
receive any such reimbursement based upon Landlord's good faith claim that such
action did not have to be taken by Landlord pursuant to the terms of this Lease,
or (ii) Landlord delivers to Tenant, within thirty (30) days after receipt of
Tenant's invoice, a written objection to the payment of such invoice based upon
Landlord's good faith claim that such charges are excessive (in which case,
Landlord shall reimburse Tenant, within such 30-day period, the amount Landlord
contends would not be excessive), then Tenant shall not be entitled to such
reimbursement or offset against Rent, but Tenant, as its sole remedy, may
proceed to institute legal proceedings to determine and collect the amount, if
any, of such reimbursement. In the event Tenant prevails in such legal
proceedings and receives a monetary judgment against Landlord, then Landlord
shall pay such judgment to Tenant within thirty (30) days of date such monetary
judgment is entered. If such monetary judgment is not so paid, then,
notwithstanding any contrary provision of this Lease, Tenant shall be entitled
to offset against the Rent payable under this Lease the amount of such monetary
judgment together with interest which shall have accrued on such monetary
judgment during the period from and after the day after the date such monetary
judgment was received through and including the date that Tenant offsets against
the Rent the amount of such monetary judgment, at the Interest Rate. In the
event Tenant undertakes such repairs and/or maintenance, and such work will
affect the Systems and Equipment, any structural portions of the Buildings, any
common areas of the Real Property or other areas outside the Buildings and/or
the exterior appearance of the Buildings or Real Property (or any portion
thereof), Tenant shall use only those unrelated third party contractors used by
Landlord in the Buildings for such work unless such contractors are unwilling or
unable to perform such work at competitive prices, in which event Tenant may
utilize the services of any other qualified contractor which normally and
regularly performs similar work in Comparable Buildings. Tenant shall comply
with the other terms and conditions of this Lease if Tenant takes the required
action, except that Tenant is not required to obtain Landlord's consent for such
repairs.

                                    ARTICLE 8

                            ADDITIONS AND ALTERATIONS

     8.1  LANDLORD'S CONSENT TO ALTERATIONS. Tenant may not make any
improvements, alterations, additions or changes to the Premises (collectively,
the "ALTERATIONS") without first procuring the prior written consent of Landlord
to such Alterations, which consent shall be requested by Tenant not less than
thirty (30) days prior to the commencement thereof. Landlord shall not
unreasonably withhold or delay its consent for any Alterations, except that
Landlord may withhold its consent, in its sole and absolute discretion, with
respect to such Alterations which (i) are located on the roof of the Building(s)
(including any telecommunications and/or other equipment thereon), (ii) can be
seen from outside the Premises or either of the Buildings, and/or (iii) are
likely to have an adverse effect on the structural components or Systems and
Equipment of the Buildings. Tenant shall pay for all overhead, general
conditions, fees and other costs and expenses of the Alterations, and shall pay
to Landlord a Landlord supervision fee of two percent (2%) of the cost of the
Alterations excluding any of Tenant's movable fixtures and equipment which are
not affixed to the Premises. The supervision fee described in the immediately
preceding sentence shall also apply to the initial build-out by or for Tenant of
any First Offer Space and/or FHS Expansion Space leased by Tenant pursuant to
this Lease.

                                      -35-
<PAGE>

Notwithstanding anything to the contrary contained in this Section 8.1, Tenant
may make non-structural interior alterations, additions or improvements to the
interior of the Premises (collectively, the "ACCEPTABLE CHANGES") without
Landlord's consent, provided that: (i) Tenant delivers to Landlord written
notice of such Acceptable Changes at least ten (10) days prior to the
commencement thereof; (ii) the aggregate cost of all such Acceptable Changes
during any twelve (12) consecutive month period does not exceed One Hundred
Fifty Thousand Dollars ($150,000.00); (iii) such Acceptable Changes shall be
performed by or on behalf of Tenant in compliance with the other provisions of
this Article 8; (iv) such Acceptable Changes do not require the issuance of a
building permit or other governmental approval; (v) such Acceptable Changes do
not affect any Systems and Equipment or the ground floor lobby areas of the
Buildings, and cannot be seen from outside the Premises; and (vi) such
Acceptable Changes shall be performed by qualified contractors and
subcontractors which normally and regularly perform similar work in Comparable
Buildings. The construction of the initial improvements to the Premises (and the
Landlord supervision fee therefor) shall be governed by the terms of the Tenant
Work Letter and not the terms of this Article 8.

     8.2  MANNER OF CONSTRUCTION. Landlord may impose, as a condition of its
consent to all Alterations or repairs of the Premises or about the Premises,
such commercially reasonable requirements as Landlord may deem desirable (and
which are not inconsistent with the rights of Tenant under this Lease),
including, but not limited to, the requirement that Tenant utilize for such
purposes only contractors, materials, mechanics and materialmen reasonably
approved by Landlord, except that Landlord may designate the contractors and
subcontractors to perform all work affecting the structural components of the
Buildings or the Systems and Equipment provided such contractors and
subcontractors are unrelated to Landlord and agree to perform such work at
competitive prices and pursuant to Tenant's reasonable scheduling requirements.
Tenant shall construct such Alterations and perform such repairs in conformance
with any and all applicable rules and regulations of any federal, state, county
or municipal code or ordinance and pursuant to a valid building permit, issued
by the city in which the Real Property is located, in conformance with
Landlord's reasonable, non-discriminatory construction rules and regulations.
Landlord's approval of the plans, specifications and working drawings for
Tenant's Alterations shall create no responsibility or liability on the part of
Landlord for their completeness, design sufficiency, or compliance with all
laws, rules and regulations of governmental agencies or authorities. All work
with respect to any Alterations must be done in a good and workmanlike manner
and diligently prosecuted to completion to the end that the Premises shall at
all times be a complete unit except during the period of work. In performing the
work of any such Alterations, Tenant shall have the work performed in such
manner as not to unreasonably obstruct access to the Buildings or Real Property
or the common areas for any other tenant of the Real Property, and as not to
obstruct the business of Landlord or other tenants in the Real Property, or
interfere with the labor force working on the Real Property. In the event that
Tenant makes any Alterations, Tenant agrees to carry "Builder's All Risk"
insurance in an amount reasonably approved by Landlord covering the construction
of such Alterations, and such other insurance as Landlord may reasonably
require, it being understood and agreed that all of such Alterations shall be
insured by Tenant pursuant to Article 10 of this Lease immediately upon
completion thereof. In addition, with respect to any Alterations to be made in
Building C which cost in excess of $50,000.00 and with respect to any
Alterations to be made in Building B which cost in excess of $150,000.00, if
such Alterations are made by any Transferee of Tenant which is other than an
Affiliate of Tenant, Landlord may, in its discretion, require such Transferee to
obtain a lien and completion bond, or, at such Transferee's option, some
alternate form of security reasonably satisfactory to Landlord, in an amount
sufficient to ensure the lien-free completion of such Alterations and naming
Landlord as a co-obligee. Upon completion of any Alterations, Tenant agrees to
cause a Notice of Completion to be recorded in the office of the Recorder of the
county in which the Real Property is located in accordance with Section 3093 of
the Civil Code of the State of California or any successor statute, and Tenant
shall deliver to the management office for the Real Property a reproducible copy
of the "as built" drawings of the Alterations.

     8.3  LANDLORD'S PROPERTY. All Alterations, improvements and/or fixtures
(excluding trade fixtures) which may be installed or placed in or about the
Premises, from time to time, shall be at the sole cost of Tenant and shall
become the property of Landlord upon expiration of the Lease Term or earlier
termination of this Lease; provided, however: (i) Tenant may not remove any
Tenant Improvements or Alterations paid for by Landlord with Landlord's own
funds or out of any tenant improvement allowances provided by Landlord (except
any such removal made in

                                      -36-
<PAGE>

connection with Alterations approved by Landlord); and (ii) Landlord may, by
written notice delivered to Tenant concurrently with Landlord's approval of the
final working drawings for any Alterations (or for the initial tenant
improvements constructed for any portion of the Premises located in Building C
or any other building in the Project other than in Building B which are made to
ready such space for Tenant's initial occupancy), identify those Alterations (or
initial tenant improvements for Tenant's initial occupancy, as the case may be)
which Landlord will require Tenant to remove at the expiration or earlier
termination of this Lease; provided further, however, that Tenant shall in no
event be required to remove any such Alterations (or initial tenant
improvements, as the case may be) other than (A) any raised floors, internal
stairwells, vaults and other similar special use tenant improvements
(collectively, "SPECIAL USE IMPROVEMENTS"), and/or (B) those other improvements
or alterations which are of such specialized nature or application that the same
are not reasonably suited for use by a successor occupant of the Premises. In no
event shall Tenant be required to remove any of the initial Tenant Improvements
constructed in Building B pursuant to the Tenant Work Letter. If Landlord
requires Tenant to remove any such Alterations (or any such initial tenant
improvements which are located in Building C or any other building in the
Project other than in Building B), Tenant, at its sole cost and expense, shall
remove the identified Alterations and improvements on or before the expiration
or earlier termination of this Lease and repair any damage to the Premises
caused by such removal. If Tenant fails to complete such removal and/or to
repair any damage caused by the removal of any Alterations or improvements,
Landlord may do so and may charge the cost thereof to Tenant.

     8.4  EQUIPMENT LEASING AND FINANCING. Notwithstanding any provision of this
Lease to the contrary, Tenant may enter into leases for, and/or grant security
interests in, Tenant's trade fixtures, equipment and personal property in the
Premises pursuant to commercially reasonable leases and/or security agreements,
and Landlord shall (i) subordinate any landlord lien rights it may have in and
to such items to the interest of the lessors and lenders therein and, in the
case of trade fixtures, waive any claim that the same are part of the Real
Property by virtue of being affixed thereto, and (ii) permit the lessors and
lenders under any such leases and security agreements to remove the leased or
encumbered property upon default by Tenant under such leases and security
agreements, so long as such removal work is performed on or prior to the
expiration or termination of this Lease and each such party repairs any damage
to the Premises caused by such removal.

                                    ARTICLE 9

                             COVENANT AGAINST LIENS

     Tenant has no authority or power to cause or permit any lien or encumbrance
of any kind whatsoever, whether created by act of Tenant, operation of law or
otherwise, to attach to or be placed upon the Real Property, Buildings or
Premises, and any and all liens and encumbrances created by Tenant shall attach
to Tenant's interest only. Landlord shall have the right at all times to post
and keep posted on the Premises any notice which it deems necessary for
protection from such liens. Tenant covenants and agrees not to suffer or permit
any lien of mechanics or materialmen or others to be placed against the Real
Property, the Buildings or the Premises with respect to work or services claimed
to have been performed for or materials claimed to have been furnished to Tenant
or the Premises, and, in case of any such lien attaching or notice of any lien,
Tenant covenants and agrees to cause it to be released and removed of record (by
payment, statutory bond or other lawful means) within ten (10) business days
after Tenant has notice of such lien. Notwithstanding anything to the contrary
set forth in this Lease, in the event that such lien is not released and removed
of record within such 10-business day period, then Landlord, at its sole option,
may immediately take all action necessary to release and remove such lien,
without any duty to investigate the validity thereof, and all reasonable sums,
costs and expenses, including reasonable attorneys' fees and costs, incurred by
Landlord in connection with such lien shall be deemed Additional Rent under this
Lease and shall be paid by Landlord to Tenant within thirty (30) days after
written demand by Landlord.

                                    INSURANCE

     10.1 INDEMNIFICATION AND WAIVER.

          10.1.1 Except as expressly provided in Section 10.1.2 below, Tenant
hereby assumes all risk of damage to property and injury to persons, in, on, or
about the Premises from any cause whatsoever and agrees that Landlord, and its
partners and subpartners, and their respective officers, agents, property
managers, employees, and independent contractors (collectively, "LANDLORD
PARTIES") shall not be liable for, and are hereby released from any
responsibility for, any damage to property or injury to persons or resulting
from the loss of use thereof, which damage or injury is sustained by Tenant or
by other persons claiming through Tenant. In addition, except as expressly
provided in Section 10.1.2 below, Tenant shall indemnify, defend, protect, and
hold harmless the Landlord Parties from any and all loss, cost, damage, expense
and liability, including without limitation court costs and reasonable
attorneys' fees (collectively, "CLAIMS") incurred in connection with or arising
from (i) any cause in, on or about the Premises (including, without limitation,
Tenant's installation, placement and removal of Alterations, improvements,
fixtures and/or equipment in, on or about the Premises), and (ii) any acts,
omissions or negligence of Tenant or of any person claiming by, through or under
Tenant, or of the contractors, agents, servants, employees, licensees or
invitees of Tenant or any such person, in, on or about the Premises, Buildings
and Real Property; provided, however, such indemnity shall not include any lost
profits, loss of business or other consequential damages.

          10.1.2 Notwithstanding the provisions of Section 10.1.1 above to the
contrary, the assumption of risk and release by Tenant set forth in Section
10.1.1 above, and Tenant's indemnity of Landlord in Section 10.1.1 above, shall
not apply to: (i) any Claims to the extent resulting from the negligence or
willful misconduct of the Landlord Parties and not insured or required to be
insured by Tenant under this Lease (collectively, the "EXCLUDED CLAIMS"); or
(ii) any loss of or damage to Landlord's property to the extent Landlord has
waived such loss or damage pursuant to Section 10.4 below. In addition, Landlord
shall indemnify, defend, protect and hold Tenant harmless from all such Excluded
Claims, except for (A) any loss or damage to Tenant's property to the extent
Tenant has waived such loss or damage pursuant to Section 10.4 below, and (B)
any lost profits, loss of business or other consequential damages.

          10.1.3 The provisions of this Section 10.1 shall survive the
expiration or sooner termination of this Lease.

     10.2 LANDLORD'S INSURANCE AND TENANT'S COMPLIANCE WITH INSURANCE
REQUIREMENTS. Landlord shall, from and after the date hereof until the
expiration of the Lease Term, maintain in effect the following insurance: (i)
physical damage insurance (including a rental loss endorsement) providing
coverage in the event of fire, vandalism, malicious mischief and all other risks
normally covered under "special form" policies in the geographical area of the
Buildings, covering the Buildings (excluding, at Landlord's option, the property
required to be insured by Tenant pursuant to Section 10.3 below) in an amount
not less than one hundred percent (100%) of the full replacement value (less
reasonable deductibles) of the Buildings, together with such other risks as
Landlord may from time to time determine (provided however, that Landlord shall
have the right, but not the obligation, to obtain earthquake and/or flood
insurance); and (ii) commercial general liability insurance including a
Commercial Broad Form Endorsement or the equivalent in the amount of at least
Ten Million Dollars ($10,000,000.00), against claims of bodily injury, personal
injury or property damage arising out of Landlord's operations, assumed
liabilities (including the liabilities assumed by Landlord under this Lease),
contractual liabilities, or use of the Buildings, common areas and Parking
Facilities. Such coverages may be carried under blanket insurance policies. The
insurers providing such insurance shall be licensed to do business in the State
of California and rated A-VII or better in "Best's Key Rating Guide," and the
policies of insurance with respect to property loss or damage by fire or other
casualty shall contain a waiver of subrogation as provided in Section 10.4
below. Upon written request from Tenant, but no more than one (1) time during
any Calendar Year, Landlord shall provide Tenant with evidence that Landlord is
carrying the insurance Landlord is required to maintain pursuant to this Section
10.2. Tenant shall, at Tenant's expense, comply as to the Premises with all
insurance company requirements pertaining to the use of the Premises. If
Tenant's conduct or use of the Premises causes any increase in the premium for
Landlord's insurance policies, then Tenant shall reimburse Landlord for any such
increase. Tenant, at
                                      -38-

<PAGE>

Tenant's expense, shall comply with all rules, orders, regulations or
requirements of the American Insurance Association (formerly the National Board
of Fire Underwriters) and with any similar body where applicable due to Tenant's
Alterations or use of the Premises.

     10.3 TENANT'S INSURANCE. From and after the date (the "INSURANCE START
DATE") which is the earlier of (i) the date Landlord delivers possession of any
portion of the Premises to Tenant in the condition required under this Lease,
(ii) the date Tenant enters any portion of the Premises to commence occupancy
thereof or perform any work under this Lease or install any of Tenant's
furniture systems and other Tenant's Property therein, or (iii) the Lease
Commencement Date, and continuing thereafter throughout the Lease Term, Tenant
shall maintain the following coverages in the following amounts.

          10.3.1 Commercial General Liability Insurance covering the insured
against claims of bodily injury, personal injury and property damage arising out
of Tenant's operations, assumed liabilities or use of the Premises, including a
Broad Form Commercial General Liability endorsement covering the insuring
provisions of this Lease and the performance by Tenant of the indemnity
agreements set forth in Section 10.1 of this Lease, for limits of liability not
less than:

        Bodily Injury and                       $5,000,000.00 each occurrence
        Property Damage Liability               $5,000,000.00 annual aggregate

        Personal Injury Liability               $5,000,000.00 each occurrence
                                                $5,000,000.00 annual aggregate

          10.3.2 Physical Damage Insurance covering (i) all office furniture,
trade fixtures, office equipment, merchandise and all other items of Tenant's
property on the Premises installed by, for, or at the expense of Tenant, (ii)
the Tenant Improvements, including any Tenant Improvements which Landlord
permits to be installed above the ceiling of the Premises or below the floor of
the Premises, and (iii) all other improvements, Alterations and additions to the
Premises, including any improvements, Alterations or additions installed at
Tenant's request above the ceiling of the Premises or below the floor of the
Premises. Such insurance shall be written on a "physical loss or damage" basis
under a "special form" policy, for the full replacement cost value new without
deduction for depreciation of the covered items and in amounts that meet any
co-insurance clauses of the policies of insurance and shall include a vandalism
and malicious mischief endorsement, and sprinkler leakage coverage.

          10.3.3 Business interruption, loss-of-income and extra expense
insurance in such amounts as will reimburse Tenant for direct or indirect loss
of earnings attributable to all perils commonly insured against by prudent
tenants or attributable to prevention of access to the Premises or to the
Buildings as a result of such perils.

          10.3.4 FORM OF POLICIES. The minimum limits of policies of insurance
required to be carried by Landlord and Tenant under this Lease shall in no event
limit the liability of Tenant or Landlord under this Lease. Tenant's insurance
shall: (i) name Landlord, and any property manager and mortgagee of Landlord, as
additional insureds, as their respective interests may appear; (ii) specifically
cover the liability assumed by Tenant under this Lease to the extent insurable
by a commercially reasonably available Commercial General Liability Policy,
including, but not limited to, Tenant's obligations under Section 10.1.1 of this
Lease; (iii) be issued by an insurance company having a rating of not less than
A-VII in Best's Insurance Guide or which is otherwise acceptable to Landlord and
licensed to do business in the State of California; (iv) be primary insurance as
to all claims thereunder and provide that any insurance carried by Landlord is
excess and is non-contributing with any insurance requirement of Tenant; (v)
provide that said insurance shall not be canceled or coverage changed unless
thirty (30) days' prior written notice shall have been given to Landlord and any
mortgagee or ground or underlying lessor of Landlord; (vi) contain a
cross-liability endorsement or severability of interest clause reasonably
acceptable to Landlord; and (vii) include commercially reasonable deductibles,
which shall in no event exceed $25,000.00 for the insurance required in Sections
10.3.2(ii) and (iii) above for the first (1st) year of the initial Lease Term
(such $25,000.00 maximum deductible may be increased after the first (1st) year
of the initial lease Term to higher commercially reasonable amounts permitted by
landlords of Comparable Buildings with respect to tenants leasing space therein
of comparable size as the Premises). Tenant shall deliver certificates of such
policies to Landlord on or before the Insurance Start Date and at least thirty
(30) days before the expiration dates thereof. In the event Tenant shall

                                      -39-
<PAGE>

fail to procure such insurance, or to deliver such policies or certificate
within such time periods, Landlord may, at its option after written notice to
Tenant, procure such policies for the account of Tenant, and the cost thereof
shall be paid to Landlord as Additional Rent within thirty (30) days after
delivery to Tenant of bills therefor.

     10.4 SUBROGATION. Landlord and Tenant agree to have their respective
insurance companies issuing property damage insurance waive any rights of
subrogation that such companies may have against Landlord or Tenant, as the case
may be. Anything in this Lease to the contrary notwithstanding (including the
provisions of Section 10.1 above), Landlord and Tenant hereby waive and release
each other of and from any and all rights of recovery, claims, actions or causes
of actions against each other, their respective agents, officers and employees,
for any loss or damage that may occur to the Premises, Buildings or Real
Property, or personal property within the Buildings, regardless of cause or
origin, including the negligence of Landlord and Tenant and their respective
agents, officers and employees, but only to the extent the releasing party's
loss or damage is covered under casualty insurance policies in effect at the
time of such loss or damage or would have been covered by the casualty insurance
required to be carried under Sections 10.2 and 10.3 above had the releasing
party complied with its applicable insurance obligations thereunder. Each party
agrees to give immediately to its respective insurance company which has issued
policies of insurance covering any risk of direct physical loss, written notice
of the terms of the mutual waivers contained in this Section 10.4, and to have
such insurance policies properly endorsed, if necessary, to prevent the
invalidation of said insurance coverage by reason of said waivers.

     10.5 ADDITIONAL INSURANCE OBLIGATIONS. Tenant shall carry and maintain at
any time following the first three (3) years of the initial Lease Term, at
Tenant's sole cost and expense, increased amounts of the insurance required to
be carried by Tenant pursuant to this Article 10, and such other reasonable
types of insurance coverage and in such reasonable amounts covering the Premises
and Tenant's operations therein, as may be reasonably requested by Landlord;
provided, however, that in no event shall such increased coverage be in excess
of that required by landlords of tenants leasing comparable-sized space in
Comparable Buildings.

                                   ARTICLE 11

                             DAMAGE AND DESTRUCTION

     11.1 REPAIR OF DAMAGE TO PREMISES BY LANDLORD. Tenant shall promptly notify
Landlord after Tenant becomes aware of any damage to the Premises resulting from
fire or any other casualty. If the Premises or any common areas of the Buildings
or Real Property serving or providing access to the Premises shall be damaged by
fire or other casualty, Landlord shall promptly and diligently, subject to
reasonable delays for insurance adjustment or other matters beyond Landlord's
reasonable control, and subject to all other terms of this Article 11, restore
the Base, Shell, and Core of the Premises and such common areas. Such
restoration shall be to substantially the same condition of the Base, Shell, and
Core of the Premises and common areas prior to the casualty, except for
modifications required by zoning and building codes and other laws, or any other
modifications to the common areas deemed desirable by Landlord provided access
to the Premises and any common restrooms serving the Premises shall not be
materially impaired thereby. Notwithstanding any other provision of this Lease,
upon the occurrence of any damage to the Premises, Tenant shall assign to
Landlord (or to any party designated by Landlord) all insurance proceeds payable
to Tenant under Tenant's insurance required under Sections 10.3.2(ii) and (iii)
of this Lease, and Landlord shall repair any injury or damage to the Tenant
Improvements and Alterations installed in the Premises and shall return such
Tenant Improvements and Alterations to their original condition; provided that
if the cost of such repair by Landlord (based on competitive pricing by all
contractors and subcontractors and without any profit mark-up or supervision
fees to Landlord) exceeds the amount of insurance proceeds received by Landlord
from Tenant's insurance carrier, as assigned by Tenant, the cost of such repairs
shall be paid by Tenant to Landlord on a progress payment basis with the first
such payment being due from Tenant after Landlord's commencement of the repair
of the damage. In connection with such repairs and replacements, Tenant shall,
prior to the commencement of construction, submit to Landlord, for Landlord's
reasonable review and approval, all plans, specifications and working drawings
relating thereto, and Landlord shall select the contractors to perform such
improvement work pursuant to Landlord's standard competitive bidding procedures.
Landlord shall not be liable for any inconvenience or annoyance to Tenant or its
visitors, or injury to Tenant's business resulting in any way from such damage
or the repair

                                      -40-
<PAGE>

thereof; provided however, that if such fire or other casualty shall have
damaged the Premises or common areas necessary to Tenant's occupancy to such a
degree that Tenant is prevented from using, and does not use, all or any part of
the Premises as a result thereof, then Landlord shall allow Tenant a
proportionate abatement of Rent during the time and to the extent Tenant is so
prevented from using and does not use the Premises as a result thereof, and such
abatement period shall continue until Tenant has been given sufficient time and
sufficient access to the Premises to rebuild such portions of the Premises
Tenant is required to rebuild, to install its property, furniture, fixtures and
equipment to the extent the same shall have been removed and/or damaged as a
result of such damage or destruction, and to move in over one (1) weekend.
Landlord shall use commercially reasonable efforts to minimize any such
inconvenience, annoyance or interference to Tenant resulting from Landlord's
repair of any damage pursuant to this Section 11.1.

     11.2 LANDLORD'S OPTION TO REPAIR. Within sixty (60) days after Landlord
becomes aware of such damage, Landlord shall notify Tenant in writing
("LANDLORD'S DAMAGE NOTICE") of the estimated time, in Landlord's reasonable
judgment, required to substantially complete the repairs of such damage (the
"ESTIMATED REPAIR Period"). Notwithstanding the terms of Section 11.1 of this
Lease, Landlord may elect not to rebuild and/or restore the Premises and/or
Buildings and instead terminate this Lease (subject, however, to the terms of
Section 11.3 below) by notifying Tenant in writing of such termination within
sixty (60) days after Landlord becomes aware of such damage, but Landlord may so
elect only if one or both of the Buildings shall be damaged by fire or other
casualty or cause, whether or not the Premises are affected (subject, however,
to the terms of Section 11.3 below), and one or more of the following conditions
is present: (i) repairs cannot in Landlord's opinion, as set forth in Landlord's
Damage Notice, reasonably be completed within one (1) year after the date
Landlord becomes aware of such damage (when such repairs are made without the
payment of overtime or other premiums); or (ii) the damage is not fully covered
by Landlord's insurance policies obtained or required to be obtained by Landlord
pursuant to Section 10.2 above and the cost of repairing such uninsured or
underinsured damage, including deductibles, exceeds the "Threshold Amount" (as
that term is defined below). As used herein, the "THRESHOLD AMOUNT" shall mean
$600,000.00 with respect to Building B and $300,000.00 with respect to Building
C, except that if at the time of such damage or destruction, Tenant is leasing
all of Building C, the Threshold Amount for Building C shall also equal
$600,000.00. If (A) Landlord does not elect to terminate this Lease pursuant to
Landlord's termination right as provided above, (B) the damage constitutes a
Tenant Damage Event (as defined below), and (C) the repair of such damage
cannot, in the reasonable opinion of Landlord, as set forth in Landlord's Damage
Notice, be completed within one (1) year after Landlord becomes aware of such
damage, then Tenant may elect to terminate this Lease (subject, however, to the
terms of Section 11.3 below) by delivering written notice thereof to Landlord
within thirty (30) days after Tenant's receipt of Landlord's Damage Notice,
which termination shall be effective as of the date of such termination notice
thereof to Landlord. As used herein, a "TENANT DAMAGE EVENT" shall mean damage
to all or any part of the Premises or any common areas of the Buildings
providing access to the Premises by fire or other casualty, which damage (x) is
not the result of the gross negligence or willful misconduct of Tenant or any of
Tenant's employees, agents, contractors, licensees or invitees, (y)
substantially interferes with Tenant's use of or access to the Premises AND (z)
would entitle Tenant to an abatement of Rent pursuant to Section 11.1 above. In
addition, in the event of a Tenant Damage Event, and if neither Landlord nor
Tenant has elected to terminate this Lease as provided hereinabove, but Landlord
fails to substantially complete the repair and restoration of such Tenant Damage
Event within the Estimated Repair Period plus ninety (90) days, plus the number
of days of delay, if any, attributable to events of "Force Majeure," as that
term is defined in Section 25.17 hereof, plus the number of days of delay, if
any, as are attributable to the acts or omissions of Tenant or Tenant's
employees, agents, contractors, licensees or invitees, then Tenant shall have an
additional right to terminate this Lease (subject, however, to the terms of
Section 11.3 below) by delivering written termination notice to Landlord within
fifteen (15) days after the expiration of such period. Further, in the event
that the Premises or the Buildings are destroyed or damaged to any substantial
extent during the last twelve (12) months of the Lease Term (except that, in the
event that Tenant shall have exercised its option to renew pursuant to the
Extension Option Rider attached to this Lease, such twelve (12) month period
shall be the last twelve (12) months of the applicable Option Term), then
notwithstanding anything contained in this Article 11, Landlord shall have the
option to terminate this Lease (subject, however, to the terms of Section 11.3
below), and to the extent such destruction or damage constitutes a Tenant Damage
Event and the repair of same is reasonably expected by Landlord to require more
than sixty (60) days to

                                      -41-
<PAGE>

substantially complete, Tenant shall have the option to terminate this Lease
(subject, however, to the terms of Section 11.3 below), by giving written
termination notice to the other party of the exercise of such option within
thirty (30) days after the date such party becomes aware of such damage or
destruction. If either Landlord or Tenant exercises any of its options to
terminate this Lease as provided above in this Section 11.2: (1) this Lease
shall cease and terminate as of the date set forth in such party's termination
notice (subject, however, to the terms of Section 11.3 below), which termination
date shall be no less than thirty (30) days and no more than one hundred twenty
(120) days after such termination notice is delivered to the other party;
provided, however, that if the termination notice is delivered as a result of a
casualty damage occurring during the last twelve (12) months of the Lease Term,
such termination date shall be no less than ten (10) days and no more than
thirty (30) days after such termination notice is delivered to such other party;
and if Landlord is the party delivering such termination notice at any time
other than during the last twelve (12) months of the Lease Term, Tenant shall
have the right to extend the termination date to a date which is one hundred
twenty (120) days after such termination notice is delivered to Tenant if
Landlord selects a termination date which is shorter than such one hundred
twenty (120) day period; (2) Tenant shall pay the Base Rent and Additional Rent,
properly apportioned up to such date of termination; and (3) subject to the
terms of Section 11.3 below, both parties hereto shall thereafter be freed and
discharged of all further obligations hereunder, except as provided for in
provisions of this Lease which by their terms survive the expiration or earlier
termination of the Lease Term.

     11.3 PARTIAL TERMINATION. Notwithstanding the foregoing provisions of
Section 11.2 to the contrary, if Landlord or Tenant would only have such right
to terminate this Lease as provided in Section 11.2 above solely as a result of
the damage caused to Building C and not to Building B, the terminating party may
only elect to terminate this Lease, if at all, on a partial basis, as to all of
the Premises then leased by Tenant in Building C and not with respect to
Building B; if the terminating party elects to terminate this Lease as to
Building C, only, in accordance with the foregoing, this Lease shall continue in
full force and effect with respect to Building B and the parties shall promptly
execute an amendment confirming such partial termination and modifying the
rentable and usable square feet, the Base Rent and Tenant's Share accordingly;
provided, however, in the event as of the date of any such damage caused to
Building C which would permit Landlord to terminate this Lease with respect to
Building C, only, pursuant to Section 11.2 and this Section 11.3, Building C is
a multi-tenant building, and the damage to Building C only affects those areas
of Building C located outside of the Premises in Building C and does not affect
the Premises in Building C, then, Landlord shall only have the right to
terminate Tenant's lease as to Building C, only, in accordance with the
foregoing in the event that Landlord also terminates all of the leases
respecting space in Building C of all of the tenants of Building C which are
situated similarly to Tenant. In determining whether other tenants of Building C
are situated similarly to Tenant, in addition to other relevant factors, an
analysis shall be made of (i) such tenants' and Landlord's rights to terminate
such leases in the event of a casualty as set forth in such leases and (ii) the
level of damage, if any, to Building C and/or such other tenants' premises.

     11.4 WAIVER OF STATUTORY PROVISIONS. The provisions of this Lease,
including this Article 11, constitute an express agreement between Landlord and
Tenant with respect to any and all damage to, or destruction of, all or any part
of the Premises, the Buildings or any other portion of the Real Property, and
any statute or regulation of the state in which the Real Property is located,
including, without limitation, Sections 1932(2) and 1933(4) of the California
Civil Code, with respect to any rights or obligations concerning damage or
destruction in the absence of an express agreement between the parties, and any
other statute or regulation, now or hereafter in effect, shall have no
application to this Lease or any damage or destruction to all or any part of the
Premises, one or both of the Buildings or any other portion of the Real
Property.

                                   ARTICLE 12

                                    NONWAIVER

     No waiver of any provision of this Lease shall be implied by any failure of
a party to enforce any remedy on account of the violation of such provision,
even if such violation shall continue or be repeated subsequently, any waiver by
a party of any provision of this Lease may only be in writing, and no express
waiver shall affect any provision other than the one specified in such waiver
and that one only for the time and in the manner specifically stated. No receipt
of monies by Landlord from Tenant after the termination of this Lease shall in
any way alter the

                                      -42-
<PAGE>

length of the Lease Term or of Tenant's right of possession hereunder or after
the giving of any notice shall reinstate, continue or extend the Lease Term or
affect any notice given Tenant prior to the receipt of such monies, it being
agreed that after the service of notice or the commencement of a suit or after
final judgment for possession of the Premises, Landlord may receive and collect
any Rent due, and the payment of said Rent shall not waive or affect said
notice, suit or judgment.

                                   ARTICLE 13

                                  CONDEMNATION

     13.1 PERMANENT TAKING. If all or any portion of the Premises, the Buildings
or the Real Property shall be taken by power of eminent domain or condemned by
any competent authority for any public or quasi-public use or purpose, or if
Landlord shall grant a deed or other instrument in lieu of such taking by
eminent domain or condemnation, Landlord shall have the option to terminate this
Lease (subject, however, to the terms of Section 13.2 below) upon ninety (90)
days' notice to Tenant, provided such notice is given no later than one hundred
eighty (180) days after the date of such taking, condemnation, reconfiguration,
vacation, deed or other instrument. If more than twenty-five percent (25%) of
the rentable square feet of the Premises is taken, if access to more than
twenty-five (25%) of the Premises is substantially impaired, or if more than
twenty-five percent (25%) of the parking spaces described in Section 10 of the
Summary attached to this Lease are taken and Landlord is unable to relocate such
spaces within the Project or within a two (2) block radius of the Project,
Tenant shall have the option to terminate this Lease (subject, however, to the
terms of Section 13.2 below) upon ninety (90) days' notice to Landlord, provided
such notice is given no later than one hundred eighty (180) days after the date
of such taking; provided, however, if any of Tenant's parking spaces are taken
and Tenant does not exercise its rights to terminate this Lease pursuant to this
Article 13, Landlord shall use commercially reasonable efforts to provide Tenant
with replacement parking spaces within the Project or within a two (2) block
radius of the Project. Landlord shall be entitled to receive the entire award or
payment in connection with any such taking, except that (i) Tenant shall have
the right to file any separate claim available to Tenant for (A) any taking of
Tenant's personal property and fixtures belonging to Tenant and removable by
Tenant upon expiration of the Lease Term pursuant to the terms of this Lease,
(B) Tenant's moving expenses and (C) interruption to or damage to Tenant's
business, and (ii) Landlord and Tenant shall each be entitled to receive fifty
percent (50%) of the "bonus value" of the leasehold estate in connection
therewith, which bonus value shall be equal to the difference between the Rent
payable under this Lease and the sum established by the condemning authority as
the award for compensation for the leasehold estate. All Rent shall be
apportioned as of the date of such termination, or the date of such taking,
whichever shall first occur. If any part of the Premises shall be taken, and
this Lease shall not be so terminated, the Rent shall be equitably abated and
Landlord shall at its sole expense restore the Buildings in which the remainder
of the Premises are located to any architecturally complete and functional
condition. Tenant hereby waives any and all rights it might otherwise have
pursuant to Section 1265.130 of the California Code of Civil Procedure.

     13.2 PARTIAL TERMINATION. Notwithstanding the foregoing provisions of
Section 13.1 to the contrary, if Landlord or Tenant would only have such right
to terminate this Lease as provided in Section 13.1 above solely as a result of
a taking of all or any portion of Building C and not a taking with respect to
Building B, the terminating party may only elect to terminate this Lease, if at
all, on a partial basis, as to all of the Premises then leased by Tenant in
Building C and not with respect to Building B; if the terminating party elects
to terminate this Lease as to Building C, only, in accordance with the
foregoing, this Lease shall continue in full force and effect with respect to
Building B and the parties shall promptly execute an amendment confirming such
partial termination and modifying the rentable and usable square feet, the Base
Rent and Tenant's Share accordingly.

     13.3 TEMPORARY TAKING. Notwithstanding anything to the contrary contained
in this Article 13, in the event of a temporary taking of all or any portion of
the Premises or access thereto for a period of one (1) year or less, then this
Lease shall not terminate but the Base Rent and the Additional Rent shall be
abated for the period of such taking in proportion to the ratio that the amount
of rentable square feet of the Premises taken bears to the total rentable square
feet of the Premises. Landlord shall be entitled to receive the entire award
made in connection with any such temporary taking.

                                   ARTICLE 14

                            ASSIGNMENT AND SUBLETTING

     14.1 TRANSFERS. Except as provided in Sections 14.7 and 14.8 below, Tenant
shall not, without the prior written consent of Landlord, assign, mortgage,
pledge, hypothecate, encumber, or permit any lien to attach to, or otherwise
transfer, this Lease or any interest hereunder, permit any assignment or other
such foregoing transfer of this Lease or any interest hereunder by operation of
law, sublet the Premises or any part thereof, or permit the use of the Premises
by any persons other than Tenant and its employees (all of the foregoing are
hereinafter sometimes referred to collectively as "TRANSFERS" and any person to
whom any Transfer is made or sought to be made is hereinafter sometimes referred
to as a "TRANSFEREE"). If Tenant shall desire Landlord's consent to any
Transfer, Tenant shall notify Landlord in writing, which notice (the "TRANSFER
NOTICE") shall include (i) the proposed effective date of the Transfer, which
shall not be less than twenty (20) days nor more than nine (9) months after the
date of delivery of the Transfer Notice, (ii) a description of the portion of
the Premises to be transferred (the "SUBJECT SPACE"), (iii) all of the terms of
the proposed Transfer and the consideration therefor, including a calculation of
the "TRANSFER PREMIUM," as that term is defined in Section 14.3 below, in
connection with such Transfer, the name and address of the proposed Transferee,
and, insofar as the same is then available, a copy of all existing and/or
proposed documentation pertaining to the proposed Transfer, including all
existing operative documents to be executed to evidence such Transfer or the
agreements incidental or related to such Transfer, and (iv) current financial
statements of the proposed Transferee certified by an officer, partner or owner
thereof, and any other information reasonably required by Landlord pursuant to
written notice delivered to Tenant within five (5) business days after
Landlord's receipt of the Transfer Notice, which will enable Landlord to
determine the financial responsibility, character, and reputation of the
proposed Transferee, nature of such Transferee's business and proposed use of
the Subject Space. Except as provided in Sections 14.7 and 14.8 below, any
Transfer made without Landlord's prior written consent shall, at Landlord's
option, be null, void and of no effect, and shall, at Landlord's option,
constitute a default by Tenant under this Lease. Whether or not Landlord shall
grant consent, Tenant shall pay Landlord's actual, documented and reasonable
legal fees (not to exceed $2,500.00 in any one instance) incurred by Landlord,
within thirty (30) days after written request by Landlord.

     14.2 LANDLORD'S CONSENT. Landlord shall not unreasonably withhold its
consent to any proposed Transfer of the Subject Space to the Transferee on the
terms specified in the Transfer Notice. Landlord shall notify Tenant of
Landlord's consent or reasonable disapproval of any such Transfer within twenty
(20) days after Landlord's receipt of the Transfer Notice and all other
information required to be delivered by Tenant to Landlord in connection with
such proposed Transfer as set forth in Section 14.1 above. In the event Landlord
does not provide Tenant notice of its approval or disapproval of a Transfer
within such 20-day period, and such failure continues for five (5) business days
after notice thereof from Tenant, such failure shall be deemed to be Landlord's
consent to such Transfer. The parties hereby agree that it shall be reasonable
under this Lease and under any applicable law for Landlord to withhold consent
to any proposed Transfer where one or more of the following apply, without
limitation as to other reasonable grounds for withholding consent:

          14.2.1 The Transferee is of a character or reputation or engaged in a
business which is not consistent with the quality of the Buildings or the Real
Property as a first-class multi-tenant office building project;

          14.2.2 The Transferee intends to use the Subject Space for purposes
which are not permitted under this Lease;

          14.2.3 The Transferee is either a governmental agency or
instrumentality thereof (i) which is that of a foreign country, or (ii) which is
of a character or reputation, is engaged in a business, or is of, or is
associated with, a political orientation or faction, which is materially
inconsistent with the quality of the Project, or which would otherwise
reasonably offend a landlord of a Comparable Building, or (iii) which is capable
of exercising the power of eminent domain or condemnation, unless, and only to
the extent, Landlord has previously approved such an occupant for other space in
the Buildings;

                                      -44-
<PAGE>


          14.2.4 The Transfer will result in more than a lawfully authorized
number of occupants per floor within the Subject Space;

          14.2.5 The Transferee is not a party of reasonable financial worth
and/or financial stability in light of the responsibilities assumed by such
Transferee on the date consent is requested, taking into account Tenant's
continuing liability hereunder;

          14.2.6 The terms of the proposed Transfer will allow the Transferee to
exercise a right of renewal, right of expansion, right of first offer, or other
similar right held by Tenant, in violation of the express terms of this Lease;
or

          14.2.7 Either the proposed Transferee, or any person or entity
which directly or indirectly, controls, is controlled by, or is under common
control with, the proposed Transferee, (i) occupies space in the Project at the
time of the request for consent and Landlord in fact has sufficient space in the
Project meeting such proposed transferee's space requirements, or (ii) is
negotiating with Landlord to lease space in the Project at such time and
Landlord in fact has sufficient space in the Project meeting such proposed
transferee's space requirements.

         If Landlord consents to any Transfer pursuant to the terms of this
Section 14.2, Tenant may, within nine (9) months after Landlord's consent, but
not later than the expiration of said nine (9)-month period, enter into such
Transfer of the Premises or portion thereof, upon substantially the same terms
and conditions as are set forth in the Transfer Notice furnished by Tenant to
Landlord pursuant to Section 14.1 of this Lease, provided that if there are any
changes in the terms and conditions from those specified in the Transfer Notice
(i) such that Landlord would initially have been entitled to refuse its consent
to such Transfer under this Section 14.2, or (ii) which would cause the proposed
Transfer to be materially more favorable to the Transferee than the terms set
forth in Tenant's original Transfer Notice, Tenant shall again submit the
Transfer to Landlord for its approval, which Landlord shall grant or withhold
within ten (10) business days after resubmittal by Tenant.

     14.3 TRANSFER PREMIUM. Except as otherwise provided in Sections 14.6 and
14.7 below, if Landlord consents to a Transfer, as a condition thereto which the
parties hereby agree is reasonable, Tenant shall pay to Landlord fifty percent
(50%) of any "Transfer Premium," as that term is defined in this Section 14.3,
received by Tenant from such Transferee. "TRANSFER PREMIUM" shall mean all rent,
additional rent, parking charges and other consideration received from such
Transferee in excess of the Rent and Additional Rent payable by Tenant under
this Lease on a per rentable square foot basis if less than all of the Premises
is transferred, after deducting (as a first priority item) the actual,
reasonable and documented expenses incurred by Tenant for (i) any changes,
alterations and improvements made to the Premises, and/or any tenant improvement
allowance provided by Tenant to the Transferee, in connection with the Transfer,
(ii) any brokerage commissions and advertising expenses in connection with the
Transfer, and (iii) reasonable legal fees incurred by Tenant in negotiating the
Transfer and obtaining Landlord's consent thereto. "Transfer Premium" shall also
include, but not be limited to, key money and bonus money paid by Transferee to
Tenant in connection with such Transfer, and any payment in excess of fair
market value for (A) services rendered by Tenant to Transferee or (B) assets,
fixtures, inventory, equipment, or furniture transferred by Tenant to Transferee
in connection with such Transfer.

     14.4 INTENTIONALLY DELETED.

     14.5 EFFECT OF TRANSFER. If Landlord consents to a Transfer, (i) the terms
and conditions of this Lease shall in no way be deemed to have been waived or
modified, (ii) such consent shall not be deemed consent to any further Transfer
by either Tenant or a Transferee, (iii) Tenant shall deliver to Landlord,
promptly after execution, an original executed copy of all documentation
pertaining to the Transfer in form reasonably acceptable to Landlord, and (iv)
no Transfer relating to this Lease or agreement entered into with respect
thereto, whether with or without Landlord's consent, shall relieve Tenant or any
guarantor of this Lease from liability under this Lease. Landlord or its
authorized representatives shall have the right at all reasonable times and upon
prior reasonable notice to Tenant to audit the books, records and papers of
Tenant relating to any Transfer, and shall have the right to make copies
thereof. If the Transfer Premium respecting any Transfer shall be found
understated, Tenant shall, within thirty (30) days after demand, pay the
deficiency together with interest thereon at the Interest Rate, and if

                                      -45-
<PAGE>

found understated by more than five percent (5%), Landlord's actual, reasonable
and documented costs of such audit.

     14.6 ADDITIONAL TRANSFERS. Except as provided in Section 14.7 below, for
purposes of this Lease, the term "TRANSFER" shall also include: (i) if Tenant is
a partnership, the withdrawal or change, voluntary, involuntary or by operation
of law, of fifty percent (50%) or more of the partners, or transfer of fifty
percent (50%) or more of partnership interests, within a twelve (12)-month
period, or the dissolution of the partnership without immediate reconstitution
thereof; and (ii) if Tenant is a closely held corporation (i.e., whose stock is
not publicly held and not traded through an exchange or over the counter), (A)
the dissolution, merger, consolidation or other reorganization of Tenant, (B)
the sale or other transfer of more than an aggregate of fifty percent (50%) of
the voting shares of Tenant within a twelve (12)-month period (other than
transfer of voting shares to immediate family members by reason of gift or
death) or (C) the sale, mortgage, hypothecation or pledge of more than an
aggregate of fifty percent (50%) of the value of the unencumbered assets of
Tenant within a twelve (12) month period. Notwithstanding the foregoing, to the
extent that the Transfer is of a type described in this Section 14.6, the terms
and conditions of Section 14.3 shall not apply with respect thereto.

     14.7 AFFILIATED COMPANIES/RESTRUCTURING OF BUSINESS ORGANIZATION. The
assignment or subletting by Tenant of all or any portion of this Lease or the
Premises to (i) FHS, (ii) a parent or subsidiary of Tenant, or (iii) any person
or entity which controls, is controlled by or under common control with Tenant,
or (iv) any entity which purchases all or substantially all of the assets of
Tenant, or (v) any entity into which Tenant is merged or consolidated (all such
persons or entities described in (i), (ii), (iii), (iv) and (v) being sometimes
hereinafter referred to as "AFFILIATES") shall not be deemed a Transfer under
this Article 14, and thus shall not be subject to Landlord's right to receive
any Transfer Premium pursuant to Section 14.3 above, provided that:

          14.7.1 any such Affiliate was not formed as a subterfuge to avoid the
obligations of this Article 14;

          14.7.2 Tenant gives Landlord at least ten (10) days' prior notice of
any such assignment or sublease to an Affiliate, which notice shall include
current financial statements of Tenant and the Affiliate evidencing satisfaction
of the net worth requirement in Section 14.7.3 below, and certified as accurate
by an independent certified public accounting firm;

          14.7.3 with respect to any assignment of this Lease to an Affiliate
(including an assignment of this Lease in connection with or resulting from a
merger, consolidation, reorganization, and/or asset purchase), or any sublease
to an Affiliate which when aggregated with all prior subleases to such Affiliate
pertain to more than one (1) floor of the Premises, Tenant and such Affiliate
assignee or subtenant have as of the effective date of any such assignment or
sublease a tangible net worth, in the aggregate, computed in accordance with
generally accepted accounting principles (but excluding goodwill as an asset),
which is sufficient to meet the obligations of Tenant under this Lease AND is
equal to or greater than the amount which is equal to the product of (i) three
(3) multiplied by (ii) the economic responsibilities for the space which is
proposed to be assigned or subleased hereunder for the portion of the Lease Term
remaining at the time of such proposed assignment or sublease;

          14.7.4 any such assignment or sublease shall be subject and
subordinate to all of the terms and provisions of this Lease, and such assignee
or sublessee shall assume, in a written document reasonably satisfactory to
Landlord and delivered to Landlord upon or prior to the effective date of such
assignment or sublease, all the obligations of Tenant under this Lease with
respect to the Subject Space which is the subject of such Transfer (other than
the amount of Base Rent payable by Tenant with respect to a sublease), and any
Affiliate assignee expressly remakes the representations and warranties of
Tenant and assumes the obligations and indemnities of Tenant set forth in
Section 25.25 below; and

          14.7.5 Tenant shall remain fully liable for all obligations to be
performed by Tenant under this Lease.

     14.8 PERMITTED SUBLEASES. Notwithstanding anything to the contrary set
forth in this Article 14, Tenant may, without Landlord's prior consent but
subject to Landlord's right to receive fifty percent (50%) of any Transfer
Premium received by Tenant in connection therewith pursuant to Section 14.3
above, sublease in the aggregate, up to, but no more than, three (3)

                                      -46-
<PAGE>

contiguous full floors of the Premises to any person or entity which is not an
Affiliate (each, a "PERMITTED SUBTENANT") so long as: (i) the proposed Permitted
Subtenant(s) do not have any of the characteristics described in Sections
14.2.1, 14.2.3, 14.2.5 or 14.2.7 above and/or the proposed sublease to the
Permitted Subtenant would not result in any of the events described in Sections
14.2.2, 14.2.4 or 14.2.6 above; (ii) the Permitted Subtenant(s) shall have no
right to subsequently sublease or assign all of any portion of their interests
in this Lease or in the Premises; (iii) occupancy by the Permitted Subtenant(s)
shall be subject and subordinate to all of the terms of this Lease, including,
without limitation, Section 14.3 above; and (iv) at least ten (10) days prior to
the date such Permitted Subtenant(s) take occupancy of the Premises, Tenant
delivers to Landlord a copy of the sublease agreement by and between Tenant and
the applicable Permitted Subtenant which sublease agreement shall include a
written acknowledgment by the Permitted Subtenant that the Permitted Subtenant
is subject and subordinate to all of the terms and conditions of this Lease and
assumes all obligations of Tenant with respect to the subleased space (other
than the obligations to Base Rent which shall be as set forth in such sublease).
Any sublease entered into by Tenant with a Permitted Subtenant in accordance
with this Section 14.8 shall be referred to herein as a "PERMITTED SUBLEASE".
Nothing in this Section 14.8 shall permit Tenant, without first obtaining
Landlord's prior consent thereto or otherwise complying with Section 14.7 above,
to sublease to any person or entity either (A) portions of full floors, (B)
non-contiguous floors or (C) more than three (3) contiguous full floors in the
aggregate at any time (I.E., no such sublease, when combined with all other
subleases previously entered into by Tenant pursuant to this Section 14.8, shall
pertain to more than three (3) contiguous full floors). Tenant may also enter
into a Permitted Sublease with an Affiliate pursuant to this Section 14.8
without having to comply with the provisions of Section 14.7 above (including
the net worth requirement set forth in Section 14.7.3 above) as long as Tenant
complies with the provisions of this Section 14.8 with respect thereto; if
Tenant so enters into a Permitted Sublease with an Affiliate and elects to have
such transaction governed by this Section 14.8 instead of Section 14.7, Tenant
shall notify Landlord thereof and the available space which Tenant may sublease
to non-Affiliates pursuant to this Section 14.8 shall be reduced accordingly.

                        SURRENDER OF PREMISES; OWNERSHIP
                          AND REMOVAL OF TRADE FIXTURES

     15.1 SURRENDER OF PREMISES. No act or thing done by Landlord or any agent
or employee of Landlord during the Lease Term shall be deemed to constitute an
acceptance by Landlord of a surrender of the Premises unless such intent is
specifically acknowledged in a writing signed by Landlord. The delivery of keys
to the Premises to Landlord or any agent or employee of Landlord shall not
constitute a surrender of the Premises or effect a termination of this Lease,
whether or not the keys are thereafter retained by Landlord, and notwithstanding
such delivery Tenant shall be entitled to the return of such keys at any
reasonable time upon request until this Lease shall have been properly
terminated. The voluntary or other surrender of this Lease by Tenant, whether
accepted by Landlord or not, or a mutual termination hereof, shall not work a
merger, and at the option of Landlord shall operate as an assignment to Landlord
of all subleases or subtenancies affecting the Premises.

     15.2 REMOVAL OF TENANT PROPERTY BY TENANT. Upon the expiration of the Lease
Term, or upon any earlier termination of this Lease, Tenant shall, subject to
the provisions of this Article 15, quit and surrender possession of the Premises
to Landlord in as good order and condition as when Tenant took possession and as
thereafter improved by Landlord and/or Tenant, reasonable wear and tear and
repairs, casualty damage and condemnation damage which are specifically made the
responsibility of Landlord hereunder excepted. Upon such expiration or
termination, Tenant shall, without expense to Landlord, remove or cause to be
removed from the Premises all debris and rubbish, and such items of furniture,
equipment, free-standing cabinet work and other articles of personal property
owned by Tenant or any person claiming under Tenant or installed or placed by
Tenant (or other person claiming under Tenant) (but not permanently affixed to
the Premises) at its expense in the Premises, as Landlord may, in its sole
discretion, require to be removed, and Tenant shall repair at its own expense
all damage to the Premises and Buildings resulting from such removal. Tenant
shall have no obligation to remove any of its cabling or other wiring at the end
of the Lease Term, but shall be obligated to remove same, at Tenant's cost, with
respect to any Reduction Space removed from the Premises pursuant to Section 1.7
above.

                                  HOLDING OVER

     If Tenant holds over after the expiration of the Lease Term hereof, with or
without the express or implied consent of Landlord, such tenancy shall be from
month-to-month only, and shall not constitute a renewal hereof or an extension
for any further term, and in such case Base Rent shall be payable at a monthly
rate equal to one hundred fifty percent (150%) of the Base Rent applicable
during the last rental period of the Lease Term under this Lease. Such
month-to-month tenancy shall be subject to every other term, covenant and
agreement contained herein. Landlord hereby expressly reserves the right to
require Tenant to surrender possession of the Premises to Landlord as provided
in this Lease upon the expiration or other termination of this Lease. The
provisions of this Article 16 shall not be deemed to limit or constitute a
waiver of any other rights or remedies of Landlord provided herein or at law. If
Tenant fails to surrender the Premises upon the termination or expiration of
this Lease, in addition to any other liabilities to Landlord accruing therefrom,
Tenant shall protect, defend, indemnify and hold Landlord harmless from all
loss, costs (including reasonable attorneys' fees) and liability resulting from
such failure, and such indemnification by Tenant shall specifically include,
without limitation, "RENTAL LOSS DAMAGES" which for purposes hereof shall mean
any claims made by any succeeding tenant founded upon such failure to surrender,
any lost profits to Landlord resulting therefrom, and any liability or loss
Landlord may reasonably expect to incur in connection with the delay of the
delivery of the Premises to the successor tenant; provided, however, that
notwithstanding the foregoing, Landlord shall not be entitled to recover any
such Rental Loss Damages from Tenant with respect to the first two (2) months of
such holdover and Landlord shall only be entitled to recover any such Rental
Loss Damages with respect to any holdover after such two (2) month period to the
extent Tenant has failed to surrender the Premises within thirty (30) days after
Landlord has notified Tenant that Landlord has executed a letter of intent or
lease with another tenant for all or any portion of the Premises and Landlord
has provided Tenant with information concerning the length of lease term and
basic rental of such letter of intent or lease.

                              ESTOPPEL CERTIFICATES

     Within twenty (20) days following a request in writing by a party, the
other party shall execute and deliver to the requesting party an estoppel
certificate, which shall be substantially in the form of EXHIBIT E, attached
hereto (or such other commercially reasonable form as may be reasonably required
by any prospective mortgagee or purchaser of the Project, or any portion
thereof, if Landlord is the requesting party, or by any Transferee or proposed
Transferee of Tenant if Tenant is the requesting party), indicating therein any
exceptions thereto that may exist at that time, and shall also contain any other
information reasonably requested by the requesting party. Failure of a party to
execute and deliver such estoppel certificate within such 20-day period, where
such failure continues for an additional five (5) days after a subsequent notice
of such failure is delivered by the requesting party to such party, shall
constitute an acknowledgment by such party that statements included in the
estoppel certificate delivered to such party by the requesting party made in
connection with a proposed sale or financing by Landlord or proposed Transfer by
Tenant, as the case may be, are true and correct, without exception.

                                   ARTICLE 18

                                  SUBORDINATION

     18.1 SUBORDINATION. This Lease is subject and subordinate to all present
and future ground or underlying leases of the Real Property and to the lien of
any mortgages or trust deeds, now or hereafter in force against the Real
Property and the Buildings, if any, and to all renewals, extensions,
modifications, consolidations and replacements thereof, and to all advances made
or hereafter to be made upon the security of such mortgages or trust deeds,
unless the holders of such mortgages or trust deeds, or the lessors under such
ground lease or underlying leases, require in writing that this Lease be
superior thereto. Notwithstanding any contrary provision of this Article 18, a
condition precedent to the subordination of this Lease to any future mortgage,
deed of trust, ground or underlying lease is that Landlord shall obtain for the
benefit of Tenant a

                                      -48-
<PAGE>


commercially reasonable subordination, non-disturbance and attornment agreement
from the mortgagee, beneficiary or lessor under such future instrument which
shall be the US Bank SNDA described below with respect to the US Bank Deed of
Trust if recorded as described below. Tenant covenants and agrees in the event
any proceedings are brought for the foreclosure of any such mortgage, or if any
ground or underlying lease is terminated, to attorn, to the purchaser upon any
such foreclosure sale, or to the lessor of such ground or underlying lease, as
the case may be, if required to do so pursuant to any subordination,
non-disturbance and attornment agreement executed by Tenant pursuant to this
Article 18, and to recognize such purchaser or lessor as the lessor under this
Lease. Tenant shall, within thirty (30) days of request by Landlord, execute
such further instruments or assurances as Landlord may reasonably deem necessary
to evidence or confirm the subordination or superiority of this Lease to any
such mortgages, trust deeds, ground leases or underlying leases. The parties
acknowledge that Landlord is in the process of obtaining new financing for the
Real Property from US Bank, which new financing, if completed, will be secured
by a deed of trust encumbering the Real Property to be recorded after the date
of execution of this Lease (the "US BANK DEED OF TRUST"). In the event that
Landlord obtains such new financing from US Bank, Tenant shall, within ten (10)
days after request by Landlord (or at Landlord's option, concurrently with
Tenant's execution of this Lease) sign, notarize and deliver to Landlord a
subordination, non-disturbance and attornment agreement substantially in the
form of EXHIBIT G attached hereto (the "US BANK SNDA"). If such new financing
with US Bank is completed, then within ninety (90) days after the later of (i)
the date the US Bank Deed of Trust is recorded, and/or (ii) the date Tenant
delivers to Landlord the US Bank SNDA executed and notarized by Tenant, Landlord
shall cause US Bank to execute the US Bank SNDA and deliver such executed US
Bank SNDA to Tenant. The effectiveness of the US Bank SNDA executed by Tenant
shall be conditioned upon the execution and delivery of the US Bank SNDA by
Landlord and US BANK to Tenant within such 90-day time period.

     18.2 EXISTING MORTGAGE. Landlord represents and warrants to Tenant that as
of the date of execution of this Lease, the Real Property is encumbered by a
deed of trust in favor of LNR Florida Funding, Inc., a Florida corporation
("EXISTING LENDER"), and there are no other deeds of trust or ground leases
encumbering the Real Property. Prior to or concurrently with the execution of
this Lease, Landlord and Tenant shall execute, and Landlord shall cause the
Existing Lender to execute, and deliver to the other party a subordination,
non-disturbance and attornment agreement in the form of EXHIBIT H attached
hereto (the "EXISTING LENDER SNDA").

                                   ARTICLE 19

                               DEFAULTS; REMEDIES

     19.1 EVENTS OF DEFAULT. The occurrence of any of the following shall
constitute a default of this Lease by Tenant:

          19.1.1 Any failure by Tenant to pay any Rent or any other charge
required to be paid under this Lease, or any part thereof, within five business
(5) days after written notice of delinquency; or

          19.1.2 Any failure by Tenant to observe or perform any other
provision, covenant or condition of this Lease to be observed or performed by
Tenant where such failure continues for thirty (30) days after written notice
thereof from Landlord to Tenant; provided, however, that if the nature of such
default is such that the same cannot reasonably be cured within a thirty (30)
day period, Tenant shall not be deemed to be in default if it diligently
commences such cure within such period and thereafter diligently proceeds to
rectify and cure said default as soon as possible; any such notice delivered by
Landlord shall, at Landlord's option, be in lieu of, and not in addition to, any
notice required under California Code of Civil Procedure Section 1161 or any
similar successor law; or

     19.2 REMEDIES UPON DEFAULT. Upon the occurrence of any default by Tenant
pursuant to Section 19.1 above which remains uncured after expiration of the
applicable notice and cure period set forth in Section 19.1 above, Landlord
shall have, in addition to any other remedies available to Landlord at law or in
equity, the option to pursue any one or more of the following remedies, each and
all of which shall be cumulative and nonexclusive, without any notice or demand
whatsoever.

                                      -49-
<PAGE>

          19.2.1 Terminate this Lease, in which event Tenant shall immediately
surrender the Premises to Landlord, and if Tenant fails to do so, Landlord may,
without prejudice to any other remedy which it may have for possession or
arrearages in rent, enter upon and take possession of the Premises and expel or
remove Tenant and any other person who may be occupying the Premises or any part
thereof, without being liable for prosecution or any claim or damages therefor;
and Landlord may recover from Tenant the following:

                    (i)  The worth at the time of award of any unpaid rent which
has been earned at the time of such termination; plus

                    (ii) The worth at the time of award of the amount by which
the unpaid rent which would have been earned after termination until the time of
award exceeds the amount of such rental loss that Tenant proves could have been
reasonably avoided; plus

                    (iii) The worth at the time of award of the amount by which
the unpaid rent for the balance of the Lease Term after the time of award
exceeds the amount of such rental loss that Tenant proves could have been
reasonably avoided; plus

                    (iv) Any other amount necessary to compensate Landlord for
all the detriment proximately caused by Tenant's failure to perform its
obligations under this Lease or which in the ordinary course of things would be
likely to result therefrom, specifically including but not limited to, brokerage
commissions and advertising expenses incurred, and expenses of remodeling the
Premises or any portion thereof for a new tenant, whether for the same or a
different use; and

                    (v)  At Landlord's election, such other amounts in addition
to or in lieu of the foregoing as may be permitted from time to time by
applicable law.

     The term "rent" as used in this Section 19.2 shall be deemed to be and to
mean all sums of every nature required to be paid by Tenant pursuant to the
terms of this Lease, whether to Landlord or to others. As used in Paragraphs
19.2.1(i) and (ii), above, the "worth at the time of award" shall be computed by
allowing interest at the Interest Rate (as defined in Section 4.5 of this
Lease). As used in Paragraph 19.2.1(iii) above, the "worth at the time of award"
shall be computed by discounting such amount at the discount rate of the Federal
Reserve Bank of San Francisco at the time of award plus one percent (1%).

          19.2.2 Landlord shall have the remedy described in California Civil
Code Section 1951.4 (lessor may continue lease in effect after lessee's breach
and abandonment and recover rent as it becomes due, if lessee has the right to
sublet or assign, subject only to reasonable limitations). Accordingly, if
Landlord does not elect to terminate this Lease on account of any default by
Tenant, Landlord may, from time to time, without terminating this Lease, enforce
all of its rights and remedies under this Lease, including the right to recover
all rent as it becomes due.

          19.2.3 Landlord may, but shall not be obligated to, make any such
payment or perform or otherwise cure any such obligation, provision, covenant or
condition on Tenant's part to be observed or performed (and may enter the
Premises for such purposes). Any such actions undertaken by Landlord pursuant to
the foregoing provisions of this Section 19.2.3 shall not be deemed a waiver of
Landlord's rights and remedies as a result of Tenant's failure to perform and
shall not release Tenant from any of its obligations under this Lease.

     19.3 PAYMENT BY TENANT. Tenant shall pay to Landlord, within thirty (30)
days after delivery by Landlord to Tenant of statements therefor, sums equal to
expenditures reasonably made and obligations incurred by Landlord in connection
with Landlord's performance or cure of any of Tenant's obligations pursuant to
the provisions of Section 19.2.3 above. Tenant's obligations under this Section
19.3 shall survive the expiration or sooner termination of the Lease Term.

     19.4 SUBLESSEES OF TENANT. If Landlord elects to terminate this Lease on
account of any default by Tenant as set forth in this Article 19, Landlord shall
have the right to terminate any and all subleases, licenses, concessions or
other consensual arrangements for possession entered into by Tenant and
affecting the Premises or may, in Landlord's sole discretion, succeed to
Tenant's interest in such subleases, licenses, concessions or arrangements. In
the event of

                                      -50-
<PAGE>

Landlord's election to succeed to Tenant's interest in any such subleases,
licenses, concessions or arrangements, Tenant shall, as of the date of notice by
Landlord of such election, have no further right to or interest in the rent or
other consideration receivable thereunder.

     19.5 WAIVER OF DEFAULT. No waiver by Landlord or Tenant of any violation or
breach of any of the terms, provisions and covenants herein contained shall be
deemed or construed to constitute a waiver of any other or later violation or
breach of the same or any other of the terms, provisions, and covenants herein
contained. Forbearance by Landlord in enforcement of one or more of the remedies
herein provided upon an event of default shall not be deemed or construed to
constitute a waiver of such default. The acceptance of any Rent hereunder by
Landlord following the occurrence of any default, whether or not known to
Landlord, shall not be deemed a waiver of any such default, except only a
default in the payment of the Rent so accepted.

     19.6 EFFORTS TO RELET. For the purposes of this Article 19, Tenant's right
to possession shall not be deemed to have been terminated by efforts of Landlord
to relet the Premises, by its acts of maintenance or preservation with respect
to the Premises, or by appointment of a receiver to protect Landlord's interests
hereunder. The foregoing enumeration is not exhaustive, but merely illustrative
of acts which may be performed by Landlord without terminating Tenant's right to
possession.

     19.7 LANDLORD'S DEFAULT. Landlord's failure to perform any of its
obligations under this Lease shall constitute a default by Landlord under this
Lease if the failure continues for thirty (30) days after Landlord receives
written notice of such failure from Tenant. If the required performance cannot
be completed within such thirty (30) day period, Landlord's failure to perform
shall not constitute a default under this Lease unless Landlord fails to attempt
to cure the failure within such thirty (30) day period and thereafter fails to
diligently and continuously attempt to complete such cure as soon as reasonably
possible thereafter.

     19.8 TENANT'S SPECIAL OFFSET RIGHT. In the event Tenant obtains a monetary
judgment from a court of competent jurisdiction against Landlord resulting from
Landlord's default under this Lease, and Landlord fails to pay the amount of
such monetary judgment to Tenant within thirty (30) days after such judgment is
entered against Landlord, and such failure continues for an additional thirty
(30) days after notice from Tenant, that Tenant intends to exercise its rights
under this Section 19.8, Tenant may offset against the Rent next due and payable
under this Lease, the amount of such monetary judgment so entered against
Landlord; provided, however, in no event shall Tenant be entitled to offset
against the Rent at any one time an amount which would exceed fifty percent
(50%) of the Rent next due and payable. For example, if the monetary judgment
amount for which Tenant is entitled to offset pursuant to this Section 19.8
equals $1,000,000.00, and the Rent next due and payable under this Lease equals
$500,000.00 per month, Tenant would only be required to offset $250,000.00
against the Rent next due and payable for each of the four (4) months following
the expiration of the second thirty (30) day period described hereinabove.

                                   ARTICLE 20

                           COVENANT OF QUIET ENJOYMENT

     Landlord covenants that Tenant, so long as Tenant is not in default under
this Lease and any applicable notice of such default has been delivered and any
applicable cure period has expired, shall, during the Lease Term, peaceably and
quietly have, hold and enjoy the Premises subject to the terms, covenants,
conditions, provisions and agreements hereof without interference by any persons
lawfully claiming by or through Landlord. The foregoing covenant is in lieu of
any other covenant express or implied.

                                   ARTICLE 21

                                      SIGNS

     21.1 FULL FLOOR TENANTS. Subject to Landlord's prior written approval,
which approval shall not be unreasonably withheld, conditioned or delayed, and
provided all signs are in keeping with the quality, design and style of the Real
Property, if any portion of the Premises comprises an entire floor of one or
both of the Buildings, Tenant, at its sole cost and expense, may install
identification signage anywhere on such full floor(s) of the Premises, including
the elevator

                                      -51-
<PAGE>

lobby of such full floor(s), provided that such signs are not visible from the
exterior of either of the Buildings.

     21.2 MULTI-TENANT FLOOR TENANTS. If Tenant occupies less than an entire
floor which is part of the Premises, Tenant's (or Tenant's assignee's or
subtenants') identifying signage on such floor shall be provided by Landlord, at
Tenant's sole cost and expense, and such signage shall comply with Landlord's
building standard signage program and be subject to Landlord's prior approval.

     21.3 BUILDING DIRECTORY. With respect to Building C, Tenant shall be
entitled to place its name and location in Building C in the Building C ground
floor lobby directory (or its equivalent) to be located in the Building C ground
floor lobby. Tenant shall have the exclusive right to display Tenant's name and
location and the names of Tenant's employees on any Building lobby directory (or
its equivalent) located in the ground floor lobby of Building B.

     21.4 PROHIBITED SIGNAGE AND OTHER ITEMS. Except as expressly provided in
this Article 21, Tenant may not install any signs, notices, logos, pictures,
names or advertisements on the exterior or roof of the Buildings or the common
areas of the Buildings or the Real Property or anywhere which can be seen from
outside the Premises. Any signs, window coverings, or blinds (even if the same
are located behind the Landlord approved window coverings for the Buildings), or
other items visible from the exterior of the Premises or Buildings are subject
to the prior approval of Landlord, in its sole discretion. Any such signs,
notices, logos, pictures, names, advertisements, window coverings, blinds or
other items visible from the exterior of the Premises or Buildings which are
installed and that have not been individually approved by Landlord pursuant to
this Article 21 or otherwise may be removed without notice by Landlord at the
sole expense of Tenant.

     21.5 EXTERIOR SIGNS. Subject to the approval of all applicable governmental
authorities, and compliance with all applicable Laws (as defined in Article 22
below) and all recorded covenants, conditions and restrictions affecting the
Real Property, and the terms of this Section 21.5, Tenant shall have the right
to install, at Tenant's cost: two (2) signs displaying Tenant's name, "Health
Net", on the top of the exterior of Building B (each of which signs shall be on
a different side of Building B), with the exact locations of such signs to be
mutually approved by Landlord and Tenant (collectively, the "BUILDING B EXTERIOR
SIGNS"); (ii) one (1) single-tenant signage monument for Building B in the
approximate location depicted on EXHIBIT A-1 attached hereto and Tenant's
identification sign thereon (which shall be the only tenant's identification
sign thereon until Tenant transfers its right to such sign as provided in
Section 21.5.1 below) displaying Tenant's name, "Health Net" (such monument sign
for Building B and Tenant's identification sign thereon is collectively referred
to herein as the "BUILDING B MONUMENT SIGN"); (iii) following the date Tenant
leases from Landlord pursuant to this Lease at least three (3) full floors in
Building C, (A) one (1) sign displaying Tenant's name, "Health Net", on the top
of the exterior of Building C on such side of Building C as Landlord shall
designate (the "BUILDING C EXTERIOR SIGN") and (B) one (1) multi-tenant shared
signage monument for Building C (the "BUILDING C MONUMENT") in the approximate
location depicted on EXHIBIT A-1 attached hereto (unless such signage monument
has already been installed by Landlord, in which case, such signage monument
shall be in such location as already installed) and Tenant's identification sign
thereon (which shall be in addition to any other tenants' identification signs
theretofore or thereafter placed on the Building C Monument by Landlord)
displaying the name, "Health Net" (Tenant's identification sign on the Building
C Monument shall be referred to herein as "TENANT'S BUILDING C MONUMENT SIGN");
and (iv) following the date Tenant leases from Landlord pursuant to this Lease
at least four (4) full floors in Building C, one (1) sign displaying Tenant's
name, "Health Net", on the top of the exterior of Building C on such side of
Building C as Landlord shall designate but which side shall be different from
the side of Building C on which the Building C Exterior sign is located (the
"ADDITIONAL BUILDING C EXTERIOR SIGN"). The graphics, materials, color, design,
lettering, lighting, size, specifications, manner of affixing and exact location
of the Building B Exterior Signs, the Building C Exterior Sign (if any), the
Building B Monument Sign, the Tenant's Building C Monument Sign (if any) and the
Additional Building C Exterior Sign (if any) (collectively, the "EXTERIOR
SIGNS") and the Building C Monument, if any, shall be subject to Landlord's
reasonable approval. If Tenant changes the name of its company from "Health Net"
to another name, Tenant shall have the right, at Tenant's sole cost and expense,
to change the Exterior Signs to reflect such new name as long as Landlord
reasonably approves of such name change on the Exterior Signs. Tenant shall pay
for all costs and expenses related to the Exterior Signs and the Building C
Monument (if

                                      -52-
<PAGE>

any), including, without limitation, costs of the design, construction,
installation, maintenance, insurance, utilities, repair and replacement thereof;
provided, however, Tenant shall only pay a pro-rata portion of such costs with
respect to the Building C Monument (as reasonably determined by Landlord or by
any common area association formed for LNR Warner Center which maintains the
Building C Monument) during the period that more than one tenant has an
identification sign thereon (although Tenant shall pay the full amount of such
costs as they pertain to Tenant's Building C Monument Sign thereon). Tenant
shall install and maintain the Exterior Signs in compliance with all laws and
subject to the applicable provisions of Articles 7 and 8 above.

          21.5.1 TRANSFERABILITY. The rights to the Exterior Signs are personal
to the Original Tenant and may not be transferred by the Original Tenant or used
by anyone else, except that Tenant shall have the right to transfer Tenant's
rights to the Exterior Signs to an Affiliate or an assignee of Tenant in
connection with Tenant's assignment of its entire interest in this Lease to such
Affiliate or assignee pursuant to Article 14 of this Lease, but any such
transfer of signage rights pursuant to this Section 21.5.1 shall be subject to
Landlord's reasonable approval of the name change on the Exterior Signs to
reflect the identity of such assignee. In addition, following the Lease
Commencement Date, Tenant shall only have such rights to the Exterior Signs and
the Building B Monument Sign when the Original Tenant or such assignee is in
actual and physical possession of at least four (4) full floors in Building B.
Further, if at any time following the date Tenant leases four (4) full floors in
Building C from Landlord pursuant to this Lease and thus had the right to the
Additional Building C Exterior Sign, either (i) Tenant no longer leases four (4)
full floors in Building C due to Tenant's exercise of its applicable Reduction
Right pursuant to Section 1.7 above, or (ii) the Original Tenant or any such
assignee is not in actual and physical possession of at least two (2) full
floors in Building C, then Tenant shall no longer have its right to the
Additional Building C Exterior Sign. Finally, if at any time following the date
Tenant leases three (3) full floors in Building C from Landlord pursuant to this
Lease and thus has the right to the Building C Exterior Sign and Building C
Monument Sign, either (A) Tenant no longer leases three (3) full floors in
Building C due to Tenant's exercise of its applicable Reduction Right pursuant
to Section 1.7 above, or (B) the Original Tenant or any such assignee is not in
actual and physical possession of at least two (2) full floors in Building C,
Tenant shall no longer have its right to the Building C Exterior Sign or the
Tenant's Building C Monument Sign.

          21.5.2 INSURANCE/MAINTENANCE/REMOVAL. Tenant shall be responsible for
maintaining insurance on the Exterior Signs as part of the insurance required to
be carried by Tenant pursuant to Section 10.3.2 above. Should the Exterior Signs
require maintenance, repairs and/or replacement as determined in Landlord's
reasonable judgment, Landlord shall have the right to provide written notice
thereof to Tenant and Tenant shall cause such repairs, replacement and/or
maintenance to be performed within twenty (20) days after receipt of such notice
from Landlord, at Tenant's sole cost and expense; provided, however, if such
repairs, replacement and/or maintenance are reasonably expected to require
longer than twenty (20) days to perform, Tenant shall commence such repairs,
replacement and/or maintenance within such twenty (20) day period and shall
diligently prosecute such repairs, replacement and maintenance to completion.
Should Tenant fail to perform such maintenance, repairs and/or replacement
within the periods described in the immediately preceding sentence, Landlord
shall have the right to cause such work to be performed and to charge Tenant as
Additional Rent for the costs of such work including interest at the Interest
Rate. Upon the expiration or earlier termination of this Lease (or prior to such
expiration or earlier termination, upon Tenant's loss of its rights to any of
the Exterior Signs pursuant to Section 21.5.1 above) Tenant shall, at Tenant's
sole cost and expense, cause to be removed all such Exterior Signs (or prior to
such expiration or earlier termination, those Exterior Signs for which Tenant
has lost such rights, as the case may be) and Tenant shall repair all damage
occasioned thereby and restore the affected areas to their original condition
prior to the installation of such signage so required to be removed; provided,
however, with respect to the Building B Monument Sign Landlord may elect to
require Tenant to remove only Tenant's identification sign thereon, but not the
monument itself, in which event Tenant shall have no obligation to make any
repairs or restoration to the Building B monument resulting from such removal.
If Tenant fails to remove such signage and repair and restore the affected areas
as provided in the immediately preceding sentence within ten (10) days following
the expiration or earlier termination of this Lease, then Landlord may perform
such work, and all costs and expenses incurred by Landlord in so performing such
work shall be reimbursed by Tenant to Landlord within twenty (20) days after
Tenant's receipt of invoice therefor including

                                      -53-

interest at the Interest Rate. The immediately preceding sentence shall survive
the expiration or earlier termination of this Lease.

                                   ARTICLE 22

                              COMPLIANCE WITH LAWS

     Tenant shall not do anything or suffer anything to be done in or about the
Premises or Buildings which will in any way conflict with any federal, state or
local laws, statutes, ordinances or other governmental rules, regulations or
requirements now in force or which may hereafter be enacted or promulgated,
including, without limitation, the Americans with Disabilities Act of 1990 and
the Entitlements defined in Section 1.1.4 above (collectively, the "LAWS"). At
its sole cost and expense, Tenant shall promptly comply with all such Laws,
including, without limitation, the making of any alterations and improvements to
the Premises. Notwithstanding the foregoing to the contrary, Landlord shall be
responsible for making all alterations and improvements required by applicable
Laws with respect to the items which are Landlord's responsibility to repair and
maintain pursuant to Section 7.2 of this Lease (i.e., the structural portions of
the Buildings, the exterior windows of the Buildings, the roof of each Building,
the Base, Shell and Core components of the Buildings and the common area of the
Real Property), and for otherwise complying with all Laws in the performance of
Landlord's other obligations under this Lease; provided, however, that Tenant
shall reimburse Landlord, within thirty (30) days after invoice, for the costs
of any such improvements and alterations and other compliance costs to the
extent necessitated by or resulting from (i) any Alterations or Tenant
Improvements installed by or on behalf of Tenant, (ii) any specific act,
omission or negligence of tenant or Tenant's agents, contractors, employees or
licensees, and/or (iii) Tenant's specific manner of use of the Premises (as
distinguished from general office use). The judgment of any court of competent
jurisdiction or the admission of Tenant in any judicial action, regardless of
whether Landlord is a party thereto, that Tenant has violated any of said Laws,
shall be conclusive of that fact as between Landlord and Tenant.

                                   ARTICLE 23

                                ENTRY BY LANDLORD

     Landlord reserves the right at all reasonable times and upon at least 48
hours' advance written notice to Tenant (except no such notice shall be required
in emergencies) to enter the Premises to: (i) inspect them; (ii) show the
Premises to prospective purchasers, or mortgagees, or to the ground or
underlying lessors and, during the last twelve (12) months of the Lease Term, to
prospective tenants; (iii) post notices of nonresponsibility; and/or (iv) alter,
improve or repair the Premises or the Buildings if necessary to comply with
current building codes or other applicable laws, or for structural alterations,
repairs or improvements to the Buildings which Landlord is required to perform
under this Lease. Notwithstanding anything to the contrary contained in this
Article 23, Landlord may enter the Premises at any time to (A) perform regularly
scheduled services required of Landlord; and (B) perform any covenants of Tenant
which Tenant fails to perform. Any such entries shall be without the abatement
of Rent (except as expressly provided in Section 6.5 of this Lease) and shall
include the right to take such reasonable steps as required to accomplish the
stated purposes. Subject to Landlord's indemnity of Tenant in Section 10.1.2
above, Tenant hereby waives any claims for damages or for any injuries or
inconvenience to or interference with Tenant's business, lost profits, any loss
of occupancy or quiet enjoyment of the Premises, and any other loss occasioned
thereby. For each of the above purposes, Landlord shall at all times have a key
with which to unlock all the doors in the Premises, excluding Tenant's vaults,
safes and special security areas designated in advance by Tenant. In an
emergency, Landlord shall have the right to use any means that Landlord may deem
proper to open the doors in and to the Premises. Any entry into the Premises in
the manner hereinbefore described shall not be deemed to be a forcible or
unlawful entry into, or a detainer of, the Premises, or an actual or
constructive eviction of Tenant from any portion of the Premises.
Notwithstanding anything to the contrary set forth above, Landlord agrees to use
commercially reasonable efforts to minimize interference with Tenant's use of
and access to the Premises as a result of Landlord's exercise of its entry
rights under this Article 23.

                                 TENANT PARKING

     24.1 TENANT'S PARKING SPACES. Tenant shall have the right to use the number
and type of parking spaces set forth in Section 10 of the Summary for parking by
Tenant's employees in the Parking Facilities. Eighty percent (80%) of such
parking spaces set forth in Section 10 of the Summary shall be located in the
Phase I Parking Structure (the "PARKING STRUCTURE SPACES"), and twenty percent
(20%) of such parking spaces set forth in Section 10 of the Summary, shall be
located in the surface parking areas of the Project's Parking Facilities as
designated by Landlord from time to time (the "SURFACE SPACES"). Notwithstanding
anything to the contrary set forth in this Lease, with respect to the original
Premises only, (i) five percent (5%) of Tenant's Parking Structure Spaces shall
be reserved for Tenant's exclusive use and such reserved spaces shall be located
immediately adjacent to the elevator lobby on the second (2nd) floor of the
Phase I Parking Structure, and (ii) five percent (5%) of Tenant's Surface Spaces
shall be reserved for Tenant's exclusive use and such reserved parking spaces
shall be located in the area of the surface parking areas of Phase I which is
immediately adjacent to Building B. If Tenant leases additional space in the
Real Property pursuant to Sections 1.5 and/or 1.6 of this Lease, Tenant shall be
entitled to use additional reserved and unreserved parking spaces in the amounts
and locations within the Parking Facilities as set forth therein. Tenant hereby
acknowledges that Landlord shall have no obligation to ensure (or enforce
against other tenants) that Tenant's reserved parking spaces are used only as
designated by Tenant. Landlord shall not grant to other tenants in the Project
the right to use parking spaces located in the Phase I Parking Structure which
when aggregated with the number of Parking Structure Spaces originally allocated
to Tenant hereinabove would exceed the number of parking spaces located in the
Phase I Parking Structure. Subject to all of the terms and conditions of this
Lease, including Sections 1.1.3, 24.4 and 25.29 and Articles 11 and 13, the
Rules and Regulations attached hereto as EXHIBIT D, the Parking Rules and
Regulations attached hereto as EXHIBIT F and all applicable Laws, Tenant shall
have access to Tenant's allocated parking spaces described in this Section 24.1
twenty-four (24) hours per day, seven (7) days per week.

     24.2 PARKING CHARGES. Tenant shall not be charged any parking charges for
the use of Tenant's parking spaces set forth in Section 10 of the Summary (and
any additional parking spaces leased by Tenant as a result of the addition of
any Pre-Third Year Offer Space pursuant to Section 1.5 above) during the initial
Lease Term, but Tenant shall be charged for the use of any such parking spaces
during the applicable Option Term(s) at the prevailing parking rates, if any,
charged by Landlord and/or Landlord's parking operator from time-to-time for
parking (at reserved and unreserved rates, as applicable) in the Parking
Facilities. In addition, Tenant shall be charged for the use of any additional
parking spaces leased by Tenant as a result of the addition of any Post-Third
Year Offer Space, Special First Offer Space and/or FHS Expansion Space leased by
Tenant pursuant to Sections 1.5 and 1.6 above at the prevailing parking rates,
if any, charged by Landlord and/or Landlord's parking operator from time-to-time
(at reserved and unreserved rates, as applicable). To the extent Tenant is
charged for parking during an Option Term or for any Post-Third Year Offer
Space, Special First Offer Space or FHS Expansion Space, Tenant shall have the
right, following written request made by Tenant to Landlord at least sixty (60)
days prior to the applicable commencement date for such Option Term or for such
space, to have such parking charges included by Landlord in the calculation of,
and as an increase in, the Base Rent payable for such Option Term, Post-Third
Year Offer Space, Special First Offer Space or FHS Expansion Space, as the case
may be, instead of as a separate parking charge; if Tenant makes such request,
Landlord shall notify Tenant of any such increase in the applicable Base Rent at
least thirty (30) days prior to such applicable commencement date (which
increase shall be based upon the parking rates in effect as such applicable
commencement date) and at least thirty (30) days prior to the date any
subsequent increase in the applicable Base Rent shall be effected based upon any
subsequent increases in the parking rates charged by Landlord for the applicable
parking spaces from time to time.

     24.3 ADDITIONAL PARKING SPACES. Further, subject to availability as
determined by Landlord in Landlord's sole discretion, Tenant shall have the
right to lease additional unreserved, undesignated parking spaces in the Parking
Facilities on a month-to-month basis (with Landlord and Tenant having the right
to terminate any such month-to-month lease(s) upon thirty (30) days' prior
notice to the other), subject to Tenant's payment to Landlord of the prevailing
monthly parking rates, if any, charged by Landlord and/or Landlord's parking
operator from time-to-time for such additional spaces so leased by Tenant.

     24.4 LIMITATIONS ON TENANT'S PARKING RIGHTS. Tenant shall abide, and cause
its employees and visitors who utilize the Parking Facilities to abide, by the
Parking Rules and Regulations attached hereto as EXHIBIT F, as may be modified
by Landlord from time to time. Landlord specifically reserves the right to
change the location, size, configuration, design, layout and all other aspects
of the Parking Facilities at any time (including without limitation,
implementing paid visitor parking) and Tenant acknowledges and agrees that
Landlord may, without incurring any liability to Tenant and without any
abatement of Rent under this Lease, from time to time, close-off or restrict
access to the Parking Facilities for purposes of permitting or facilitating any
such construction, alteration or improvements; provided, however, that Landlord
shall not reduce the number of Tenant's parking spaces on a permanent basis
below the number set forth in Section 10 of the Summary and Landlord shall act
reasonably to avoid or minimize any unreasonable disruption to Tenant's use of
Tenant's allocated parking spaces in the Parking Facilities. The parking rights
provided to Tenant pursuant to this Article 28 are provided solely for use by
Tenant's own personnel and such rights may not be transferred, assigned,
subleased or otherwise alienated by Tenant without Landlord's prior approval,
except in connection with an assignment of this Lease or sublease of the
Premises made in accordance with Article 14 above. All visitor parking by
Tenant's visitors shall be subject to availability, as reasonably determined by
Landlord, parking in such visitor parking areas as may be designated by Landlord
from time to time, and payment by such visitors of the prevailing visitor
parking rate charged by Landlord from time to time.

                                   ARTICLE 25

                            MISCELLANEOUS PROVISIONS

     25.1 TERMS. The necessary grammatical changes required to make the
provisions hereof apply either to corporations or partnerships or individuals,
men or women, as the case may require, shall in all cases be assumed as though
in each case fully expressed.

     25.2 BINDING EFFECT. Subject to Section 25.5 below, each of the provisions
of this Lease shall extend to and shall, as the case may require, bind or inure
to the benefit not only of Landlord and of Tenant, but also of their respective
successors or assigns, provided this clause shall not permit any assignment by
Tenant contrary to the provisions of Article 14 of this Lease.

     25.3 NO AIR RIGHTS. No rights to any view or to light or air over any
property, whether belonging to Landlord or any other person, are granted to
Tenant by this Lease. If at any time any windows of the Premises are temporarily
darkened or the light or view therefrom is obstructed by reason of any repairs,
improvements, maintenance or cleaning in or about the Buildings, the same shall
be without liability to Landlord and without any reduction or diminution of
Tenant's obligations under this Lease.

     25.4 Intentionally Deleted

     25.5 TRANSFER OF LANDLORD'S INTEREST. Tenant acknowledges that Landlord has
the right to transfer all or any portion of its interest in the Real Property,
the Buildings and/or this Lease, and Tenant agrees that in the event of any such
transfer, Landlord shall be released from all liability under this Lease arising
after the effective date of such transfer (to the extent such liability relates
to the interest transferred) provided such obligations are expressly assumed by
the transferee, and Tenant agrees to look solely to such transferee for the
performance of Landlord's obligations hereunder arising after the date of
transfer. Notwithstanding the foregoing, Tenant acknowledges that Landlord
anticipates that it will transfer all of its interest under this Lease to an
affiliate of DCA Homes, Inc., Lennar Rolling Ridge, Inc. or LNR Property
Corporation, or any entity in which any of the foregoing has an ownership
interest (an "LNR AFFILIATE"), in which event the original Landlord executing
this Lease shall be released from all liability under this Lease whether or not
such liability arose prior to or arises after the date of transfer provided such
obligations are expressly assumed by the LNR Affiliate transferee, and Tenant
agrees to look solely to such LNR Affiliate transferee for the performance of
Landlord's obligations. The liability of any transferee of Landlord shall be
limited to the interest of such transferee in the Real Property and Buildings
and such transferee shall be without personal liability under this Lease, and
Tenant hereby expressly waives and releases such personal liability on behalf of
itself and all persons claiming by, through or under Tenant. Tenant further
acknowledges that Landlord may assign its interest in this Lease to a mortgage
lender as additional security and agrees that such an assignment shall not
release Landlord from its

                                      -56-
<PAGE>

obligations hereunder and that Tenant shall continue to look to Landlord for the
performance of its obligations hereunder. Notwithstanding the foregoing
provisions to the contrary, Tenant acknowledges that Landlord's obligations to
construct a restaurant and child care facility pursuant to Section 1.1.4 of this
Lease, and Landlord's obligation to provide FHS Expansion Space to Tenant
pursuant to Section 1.6 of this Lease, shall not be binding upon: (i) any
mortgagee (other than the Existing Lender, as defined in Section 18.2) who
forecloses upon all or any portion of the Real Property or receives a deed in
lieu of foreclosure thereof (a "FORECLOSING MORTGAGEE") or any portion of the
Real Property transferred to such Foreclosing Mortgagee in such foreclosure
proceedings or deed in lieu of foreclosure, except to the extent such
Foreclosing Mortgagee has expressly assumed or agreed to be bound by such
obligations in a subordination, non-disturbance and attornment agreement
delivered to Landlord and Tenant pursuant to Article 18 of this Lease; or (ii)
any other transferee of the Real Property which is other than an LNR Affiliate
(or the portion of the Real Property transferred to such transferee) if
following such transfer Landlord (or any LNR Affiliate assignee) retains
ownership of any portion of the Real Property upon which Landlord may construct
the restaurant and child care facility and/or provide the FHS Expansion Space to
Tenant, as the case may be; provided that to the extent any transferee which
acquires any portion of the Real Property from Landlord or an LNR Affiliate
expressly assumes Landlord's obligations under Section 1.1.4 and/or 1.6,
Landlord shall be relieved of such obligations with respect to all of the Real
Property then retained by Landlord or the LNR Affiliate.

     25.6 PROHIBITION AGAINST RECORDING. Neither this Lease, nor any memorandum,
affidavit or other writing with respect thereto, shall be recorded by Tenant or
by anyone acting through, under or on behalf of Tenant, and the recording
thereof in violation of this provision shall make this Lease null and void at
Landlord's election.

     25.7 LANDLORD'S TITLE. Landlord's title is and always shall be paramount to
the title of Tenant. Nothing herein contained shall empower Tenant to do any act
which can, shall or may encumber the title of Landlord beyond such encumbrances
as are created by this Lease.

     25.8 CAPTIONS. The captions of Articles and Sections are for convenience
only and shall not be deemed to limit, construe, affect or alter the meaning of
such Articles and Sections.

     25.9 RELATIONSHIP OF PARTIES. Nothing contained in this Lease shall be
deemed or construed by the parties hereto or by any third party to create the
relationship of principal and agent, partnership, joint venturer or any
association between Landlord and Tenant, it being expressly understood and
agreed that neither the method of computation of Rent nor any act of the parties
hereto shall be deemed to create any relationship between Landlord and Tenant
other than the relationship of landlord and tenant.

     25.10 APPLICATION OF PAYMENTS. Landlord shall have the right to apply
payments received from Tenant pursuant to this Lease, regardless of Tenant's
designation of such payments, to satisfy any obligations of Tenant hereunder, in
such order and amounts as Landlord, in its sole discretion, may elect.

     25.11 TIME OF ESSENCE. Time is of the essence of this Lease and each of its
provisions.


     25.12 PARTIAL INVALIDITY. If any term, provision or condition contained in
this Lease shall, to any extent, be invalid or unenforceable, the remainder of
this Lease, or the application of such term, provision or condition to persons
or circumstances other than those with respect to which it is invalid or
unenforceable, shall not be affected thereby, and each and every other term,
provision and condition of this Lease shall be valid and enforceable to the
fullest extent possible permitted by law.

     25.13 NO WARRANTY. In executing and delivering this Lease, neither Landlord
nor Tenant has relied on any representation or any warranty or any statement of
the other party which is not set forth herein or in one or more of the exhibits
or riders attached hereto.

     25.14 LANDLORD EXCULPATION. It is expressly understood and agreed that
notwithstanding anything in this Lease to the contrary, and notwithstanding any
applicable law to the contrary, the liability of Landlord and the Landlord
Parties hereunder (including any successor landlord) and any recourse by Tenant
against Landlord or the Landlord Parties shall be limited solely and exclusively
to an amount which is equal to the interest of Landlord in the Real Property,
and

                                      -57-
<PAGE>

neither Landlord, nor any of the Landlord Parties shall have any personal
liability therefor, and Tenant hereby expressly waives and releases such
personal liability on behalf of itself and all persons claiming by, through or
under Tenant.

     25.15 ENTIRE AGREEMENT. It is understood and acknowledged that there are no
oral agreements between the parties hereto affecting this Lease and this Lease
supersedes and cancels any and all previous negotiations, arrangements,
brochures, agreements and understandings, if any, between the parties hereto or
displayed by Landlord to Tenant with respect to the subject matter thereof, and
none thereof shall be used to interpret or construe this Lease. This Lease
(including the exhibits and riders which are attached hereto and constitute an
integral part of this Lease) and any side letter or separate agreement executed
by Landlord and Tenant in connection with this Lease and dated of even date
herewith contain all of the terms, covenants, conditions, warranties and
agreements of the parties relating in any manner to the rental, use and
occupancy of the Premises, shall be considered to be the only agreement between
the parties hereto and their representatives and agents, and none of the terms,
covenants, conditions or provisions of this Lease can be modified, deleted or
added to except in writing signed by the parties hereto. All negotiations and
oral agreements acceptable to both parties have been merged into and are
included herein. There are no other representations or warranties between the
parties, and all reliance with respect to representations is based totally upon
the representations and agreements contained in this Lease.

     25.16 RIGHT TO LEASE. Landlord reserves the absolute right to effect such
other tenancies in the Buildings, the Existing Buildings and/or any other
portion of the Real Property as Landlord in the exercise of its sole business
judgment shall determine to best promote the interests of the Real Property.
Tenant does not rely on the fact, nor does Landlord represent, that any specific
tenant or type or number of tenants shall, during the Lease Term, occupy any
space in the Real Property.

     25.17 FORCE MAJEURE. Any prevention, delay or stoppage due to strikes,
lockouts, labor disputes, rain or other inclement weather, acts of God,
inability to obtain services, labor, or materials or reasonable substitutes
therefor, governmental actions or inactions, including, without limitation, any
delays in obtaining permits or approvals from the applicable governmental
authorities, civil commotions, fire or other casualty, and other causes beyond
the reasonable control of the party obligated to perform, except with respect to
the obligations imposed on Tenant under the Tenant Work Letter or with regard to
Rent and other charges to be paid by Tenant pursuant to this Lease, or monetary
amounts required to be paid by Landlord pursuant to this Lease (collectively,
the "FORCE MAJEURE"), notwithstanding anything to the contrary contained in this
Lease, shall excuse the performance of such party for a period equal to any such
prevention, delay or stoppage and, therefore, if this Lease specifies a time
period for performance of an obligation of either party, that time period shall
be extended by the period of any delay in such party's performance caused by a
Force Majeure.

     25.18 CONSENTS AND APPROVALS. Any time the consent or approval of Landlord
or Tenant is required under this Lease (including any approval rights of
Landlord while acting as "Declarant" under any covenants, conditions or
restrictions recorded against the Real Property to the extent such approval
pertains to rights granted to Tenant under this Lease), such consent or approval
shall not be unreasonably withheld, conditioned or delayed, and whenever this
Lease grants Landlord or Tenant the right to take action, exercise discretion,
establish rules and regulations or make an allocation or other determination,
Landlord and Tenant shall act reasonably and in good faith. Notwithstanding the
foregoing, (i) Landlord shall be entitled to grant or withhold its consent or
approval or exercise its discretion in its sole and absolute discretion with
respect to (A) matters which could affect the common areas of the Real Property
or the exterior appearance of the Buildings or Real Property, (B) actions taken
by Landlord pursuant to Article 19 of this Lease, or (C) matters which could
have an adverse effect on the structural components or Systems and Equipment of
the Buildings, and (ii) Landlord and Tenant shall grant or withhold its consent
or exercise its discretion with respect to matters for which there is a standard
of consent, approval or discretion specifically set forth in this Lease in
accordance with such specific standards.

     25.19 NOTICES. All notices, demands, statements or communications
(collectively, "NOTICES") given or required to be given by either party to the
other hereunder shall be in writing, shall be sent by United States certified or
registered mail, postage prepaid, return receipt requested, or delivered
personally or sent by nationally recognized overnight courier (i) to

                                      -58-
<PAGE>

Tenant at the appropriate address set forth in Section 5 of the Summary, or to
such other place as Tenant may from time to time designate in a Notice to
Landlord; or (ii) to Landlord at the addresses set forth in Section 3 of the
Summary, or to such other firm or to such other place as Landlord may from time
to time designate in a Notice to Tenant. Any Notice will be deemed given (A) on
the date which is three (3) business days after it is mailed as provided in this
Section 25.19, or (B) upon the date personal delivery is made, or (C) upon the
date which is one (1) business day after it is sent by nationally recognized
overnight courier, as the case may be. If Tenant is notified of the identity and
address of Landlord's mortgagee or ground or underlying lessor, Tenant shall
give to such mortgagee or ground or underlying lessor written notice of any
default by Landlord under the terms of this Lease by registered or certified
mail, and such mortgagee or ground or underlying lessor shall be given a
reasonable opportunity to cure such default prior to Tenant's exercising any
remedy available to Tenant.

     25.20 JOINT AND SEVERAL. If there is more than one Tenant, the obligations
imposed upon Tenant under this Lease shall be joint and several.

     25.21 AUTHORITY. Each party hereby represents and warrants to the other
party that the representing party is a duly formed and existing corporation
qualified to do business in the State of California and that the representing
party has full right and authority to execute and deliver this Lease and that
each person signing on behalf of the representing party is authorized to do so.
Each party is making the foregoing representations knowing that the other party
will rely thereon.

     25.22 ATTORNEYS' FEES JURY TRIAL. IF EITHER PARTY COMMENCES LITIGATION
AGAINST THE OTHER FOR THE SPECIFIC PERFORMANCE OF THIS lEASE, FOR DAMAGES FOR
THE BREACH HEREOF OR OTHERWISE FOR ENFORCEMENT OF ANY REMEDY HEREUNDER, THE
PARTIES HERETO AGREE TO AND HEREBY DO WAIVE ANY RIGHT TO A TRIAL BY JURY AND, IN
THE EVENT OF ANY SUCH COMMENCEMENT OF LITIGATION, THE PREVAILING PARTY SHALL BE
ENTITLED TO RECOVER FROM THE OTHER PARTY SUCH COSTS AND REASONABLE ATTORNEYS'
FEES AS MAY HAVE BEEN INCURRED, INCLUDING ANY AND ALL COSTS INCURRED IN
ENFORCING, PERFECTING AND EXECUTING SUCH JUDGMENT.

     25.23 GOVERNING LAW. This Lease shall be construed and enforced in
accordance with the laws of the State of California.

     25.24 SUBMISSION OF LEASE. Submission of this instrument for examination or
signature by Tenant does not constitute a reservation of or an option for lease,
and it is not effective as a lease or otherwise until execution and delivery by
both Landlord and Tenant.

     25.25 BROKERS.

          25.25.1 REPRESENTATIONS, COVENANTS, PAYMENT AND Indemnity. Tenant
hereby represents and warrants to Landlord that: (i) Tenant has had no dealings
with any real estate broker or agent in connection with the negotiation of this
Lease on Tenant's behalf, excepting only Cushman & Wakefield of California, Inc.
("TENANT'S BROKER"); (ii) Tenant has engaged and will continue to engage
Tenant's Broker as the exclusive broker representing Tenant and any Affiliate
assignee of Tenant in connection with this Lease with respect to any space
leased by Tenant and/or such Affiliate assignee in the Project for the first
fifteen (15) years of the Lease Term (inclusive of renewals and extensions)
commencing as of the Lease Commencement Date, whether or not pursuant to any
formal renewal or expansion provisions (including but not limited to any first
offer or first refusal rights) contained in this Lease, including, without
limitation, (A) any renewals of this Lease pursuant to the Extension Option
Rider attached to this Lease (but not with respect to any renewals beyond such
15-year period), and (B) the leasing of any additional space pursuant to
Sections 1.5 and/or 1.6 of this Lease (whether or not such leasing is pursuant
to an amendment to this Lease or a separate lease therefor and whether or not
Section 1.6 of this Lease is removed from this Lease and put into a separate
lease agreement pursuant to Section 1.6.7); and (iii) Tenant has no actual
knowledge of any other real estate broker or agent who is or in the future will
be entitled to a commission in connection with this Lease or any such renewals
or expansions on Tenant's or such Affiliate assignee's behalf. Landlord
represents and warrants to Tenant that Landlord has engaged Lee & Associates-Los
Angeles North, Inc. ("LANDLORD'S BROKER") as Landlord's broker in connection
with the

                                      -59-
<PAGE>

execution of this Lease, and Landlord shall pay the brokerage commissions owing
to Landlord's Broker in connection with the transactions contemplated by this
Lease pursuant to the terms of a separate written agreement between Landlord and
Landlord's Broker. Landlord shall pay the brokerage commissions owing to
Tenant's Broker in connection with the transactions contemplated by this Lease
pursuant to that certain Commission Agreement for Health Net dated September 13,
2000 between Landlord and Tenant's Broker, a copy of which is attached hereto as
EXHIBIT I (the "TENANT'S BROKER COMMISSION AGREEMENT"). If Tenant or any such
Affiliate assignee subsequently engages any real estate broker or agent other
than Tenant's Broker in connection with this Lease and/or any renewals,
expansions or other transactions for which Landlord or any grantee or successor
of Landlord would be obligated to pay Tenant's Broker a commission pursuant to
Tenant's Broker Commission Agreement, Tenant (and with respect to any such
transactions involving an Affiliate assignee, such Affiliate assignee) shall be
solely responsible for and shall pay to such other brokers all commissions and
other fees and compensation owing or alleged to be owing to such other brokers
in connection therewith. Tenant (and with respect to any such transactions
described above involving an Affiliate assignee, such Affiliate assignee) shall
indemnify, defend, protect and hold Landlord harmless from and against any and
all costs, expenses, liabilities, demands, actions, causes of action and claims,
including, without limitation, reasonable attorneys' fees and court costs (1)
arising out of or related to any breach by Tenant (or such Affiliate assignee,
as the case may be) of any representations, warranties and/or covenants set
forth in this Section 25.25, and (2) with respect to any leasing or brokerage
commissions, fees or equivalent compensation alleged to be owing to any real
estate broker or agent other than Tenant's Broker on account of Tenant's and/or
such Affiliate assignee's dealings with any such other real estate broker or
agent in connection with this Lease, any renewals or expansions pursuant to the
Extension Option Rider and/or Sections 1.5 and/or 1.6 of this Lease, and/or any
renewals, expansions or other transactions for which Landlord or any grantee or
successor of Landlord would be obligated to pay a commission to Tenant's Broker
pursuant to Tenant's Broker Commission Agreement. The terms of this Section
25.25 shall survive the expiration or earlier termination of this Lease. Any
Affiliate succeeding to Tenant's interest in this Lease shall, upon succeeding
to Tenant's interest, automatically be bound by the provisions, and assume the
obligations and indemnifications of Tenant set forth in this Section 25.25
without the need for any further documentation therefor.

          25.25.2 LNR GUARANTY. If Landlord fails to timely pay the commissions
owing to Tenant's Broker pursuant to Section 2a of the Tenant's Broker
Commission Agreement with respect to the initial Leased Premises leased by
Tenant under this Lease (I.E., the Premises located in Building B and floors 3,
4 and 5 of Building C) for the initial 10-year Lease Term therefor, within
thirty (30) days after the execution and delivery of this Lease by Landlord and
Tenant as provided in Section 2a (the "INITIAL COMMISSION PAYMENT"), Tenant may
make such Initial Commission Payment to Tenant's Broker and the amount of the
Initial Commission Payment so made by Tenant shall be repaid by Landlord to
Tenant within ten (10) days after written demand by Tenant to Landlord, which
repayment obligation shall be guaranteed by LNR Property Corporation in the LNR
Guaranty attached to the Tenant Work Letter as SCHEDULE 3. Tenant's payment
rights and Landlord's repayment obligations to be guaranteed by LNR Property
Corporation pursuant to this Section 25.25.2 shall not apply to any commissions
payable to Tenant's Broker with respect to expansions or renewals under Section
6 of the Tenant's Broker Commission Agreement.

     25.26 INDEPENDENT COVENANTS. This Lease shall be construed as though the
covenants herein between Landlord and Tenant are independent and not dependent
and Tenant hereby expressly waives the benefit of any statute to the contrary
and agrees that if Landlord fails to perform its obligations set forth herein,
Tenant shall not be entitled to make any repairs or perform any acts hereunder
at Landlord's expense or to any setoff of the Rent or other amounts owing
hereunder against Landlord; provided, however, that the foregoing shall in no
way impair Tenant's express rights as stated elsewhere in this Lease; provided,
further, however, that the foregoing shall also not impair the right of Tenant
to commence a separate action against Landlord for any violation by Landlord of
the provisions hereof so long as notice is first given to Landlord and any
holder of a mortgage or deed of trust covering the Buildings, Real Property or
any portion thereof, of whose address Tenant has theretofore been notified, and
an opportunity is granted to Landlord and such holder to correct such violations
as provided above.

     25.27 BUILDING NAME AND SIGNAGE. Landlord shall have the right at any time
to change or designate the name of Building C and the Real Property and to
install, affix and maintain any and all signs on the exterior of the Real
Property and on the exterior and interior of Building C,

                                      -60-
<PAGE>

but after the Lease Commencement Date Landlord shall have no right to place or
allow any signs identifying any tenant or any owner on Building B or on the
Building B Monument Sign described in Section 21.5 above.

     25.28 TRANSPORTATION MANAGEMENT. In addition to Tenant's obligations in
Section 5.1 above, if required by law, Landlord and Tenant shall fully comply
with all present or future programs intended to manage parking, transportation
or traffic in and around the Real Property, and in connection therewith, Tenant
shall take responsible action for the transportation planning and management of
all employees located at the Premises by working directly with Landlord, any
governmental transportation management organization or any other
transportation-related committees or entities.

     25.29 LANDLORD'S CONSTRUCTION. Tenant acknowledges that prior to and during
the Lease Term, Landlord (and/or any common area association) will be completing
construction and/or demolition work pertaining to various portions of the
Buildings and Real Property, including without limitation, the Phase I Parking
Structure, landscaping and tenant improvements for premises for other tenants
and, at Landlord's sole election, such other buildings, parking facilities,
improvements, landscaping and other facilities within or as part of the Project
as Landlord (and/or such common area association) shall from time to time desire
(collectively, the "CONSTRUCTION"). In connection with such Construction,
Landlord (and/or any common area association) may, among other things, erect
scaffolding or other necessary structures in the Buildings, limit or eliminate
access to portions of the Real Property, including portions of the common areas,
access roads and parking facilities, or perform work in or around the Buildings
or Real Property, which work may create noise, dust or leave debris. Tenant
hereby agrees that such Construction and Landlord's (and/or such common area
association's) actions in connection with such Construction shall in no way
constitute a constructive eviction of Tenant nor (except as provided in Section
6.5) entitle Tenant to any abatement of Rent. Landlord shall have no
responsibility or for any reason be liable to Tenant for any direct or indirect
injury to or interference with Tenant's business arising from the Construction,
nor shall Tenant be entitled to any compensation or damages from Landlord for
loss of the use of the whole or any part of the Premises or of Tenant's personal
property or improvements resulting from the Construction or Landlord's (and/or
such common area association's) actions in connection with such Construction, or
for any inconvenience or annoyance occasioned by such Construction or Landlord's
(and/or such common area association's) actions in connection with such
Construction; provided, however, that (i) Landlord agrees to use commercially
reasonable efforts to minimize interference with Tenant's use of and access to
the Premises as a result of such Construction, (ii) Landlord shall perform such
Construction in compliance with all applicable Laws in effect as of any time
such Construction is performed, including, without limitation, all Environmental
Laws and (iii) except in emergencies, after the Lease Commencement Date,
Landlord shall direct that all construction trucks used in connection with such
Construction not access the Real Property during such Construction over the
proposed private street leading from Burbank Boulevard as depicted on EXHIBIT
A-1 attached hereto.

     25.30 ROOFTOP RIGHTS.

          25.30.1 Subject to (i) the approval of all applicable governmental
agencies, (ii) Tenant's compliance with all applicable Laws, (iii) the
provisions of this Lease, and (iv) the provisions, and Tenant's compliance with
and obtaining all approvals required under, all covenants, conditions and
restrictions now or hereafter recorded against or affecting the Real Property,
Landlord hereby agrees that Tenant shall have the non-exclusive right, at
Tenant's sole cost and expense, to install on the roof of Building B and
Building C, in such locations as shall be reasonably approved by Landlord, one
(1) or more telecommunication antennae, satellite dishes and similar
telecommunication equipment (collectively, the "TELECOMMUNICATION DEVICES"). In
addition, Tenant shall have the right, subject to available capacity of Building
B and Building C, to install such connection equipment, such as conduits,
cables, risers, feeders and materials (collectively, the "CONNECTING EQUIPMENT")
in the shafts, ducts, conduits, chases, utility closets and other facilities of
Building B and Building C, respectively, as is reasonably necessary to connect
the Telecommunication Devices to Tenant's other machinery and equipment in the
Premises, subject however, to the provisions of Section 25.30.2 below. Tenant
shall also have the right of access, consistent with Section 25.30.2 below, to
the areas where any such Connecting Equipment is located for the purposes of
maintaining, repairing, testing and replacing the same. The Telecommunication
Devices and the Connecting Equipment shall be referred to herein together or
separately as the "TELECOMMUNICATION EQUIPMENT".

                                      -61-
<PAGE>

Notwithstanding the foregoing to the contrary, (A) Tenant shall only have the
rights to install and have access to the Telecommunication Equipment with
respect to Building C while Tenant is leasing space in Building C, and (B) the
area of the roof of Building C upon which Tenant may install its
Telecommunication Devices shall not exceed one hundred fifty (150) square feet
in the aggregate. None of the rights granted to Tenant pursuant to this Section
25.30, including without limitation, Tenant's right to install on the roof of
Building B the Telecommunication Devices, shall derogate from the rights granted
to Landlord pursuant to Section 1.3 above. Landlord agrees that in exercising
its rights as "Declarant" under any covenants, conditions and restrictions
recorded against the Real Property, Landlord shall not act (or fail to act) in a
manner (including without limitation, enacting any amendment thereto while
Landlord has the unilateral right to do so as Declarant thereunder) which would
materially diminish Tenant's rights under this Section 25.30.

          25.30.2 The installation of the Telecommunication Equipment shall
constitute work and shall be performed in accordance with and subject to the
provisions of Article 8 of this Lease, including, without limitation, Tenant's
obligation to obtain Landlord's prior written consent to the specifications and
manner of installation of the Telecommunication Equipment, and the
Telecommunication Equipment shall be treated for all purposes of this Lease as
if the same were Tenant's property. In no event shall Tenant be permitted to
penetrate the roof of the Buildings or void any warranties pertaining to the
Buildings in connection with Tenant's installation of the Telecommunication
Equipment. For the purposes of determining Tenant's obligations with respect to
its use of the roof herein provided, the portion of the roof and the exterior of
the Buildings affected by the Telecommunication Equipment shall be deemed to be
a portion of Tenant's Premises; consequently, all of the provisions of this
Lease respecting Tenant's obligations hereunder shall apply to the installation,
use and maintenance of the Telecommunication Equipment, including, without
limitation, provisions relating to compliance with requirements as to insurance,
indemnity, repairs and maintenance. Landlord shall have no obligation with
regard to the portions of the roof where the Telecommunications Equipment is
located.

          25.30.3 It is expressly understood that Landlord retains the right to
use the roof of each of the Buildings for any reasonable purpose whatsoever
including to perform Landlord's obligations under this Lease and/or install or
permit other tenants and other parties to install telecommunications equipment
thereon, provided that Tenant shall have reasonable access to, and Landlord
shall not unduly interfere with Tenant's use of, the Telecommunication Equipment
located thereon.

          25.30.4 Tenant shall install, use, maintain and repair the
Telecommunication Equipment so as not to cause damage to or interfere with (i)
the operation of the Buildings or the Project's Systems and Equipment and/or
(ii) the operation of the businesses of other tenants, or occupants or licensees
of the Project or the systems and equipment of such tenants, occupants or
licensees located in the Project, and Tenant hereby agrees to indemnify, defend
and hold Landlord harmless from and against any and all claims, costs, damages,
expenses and liabilities (including attorney's fees) arising out of Tenant's
failure to comply with the provisions of this Section 25.30.4.

          25.30.5 Landlord shall not have any obligations with respect to the
Telecommunication Equipment or compliance with any requirements relating thereto
nor shall Landlord be responsible for any damage that may be caused to the
Telecommunication Equipment, except to the extent caused by the gross negligence
or willful misconduct of Landlord and not insured or required to be insured by
Tenant under this Lease. Landlord makes no representation that the
Telecommunication Equipment will be able to receive or transmit communication
signals without interference or disturbance, and Tenant agrees that Landlord
shall not be liable to Tenant therefor. Landlord agrees to use good faith
efforts to minimize interference or disturbance to the Telecommunication
Equipment.

          25.30.6 Tenant, at Tenant's sole cost and expense, shall paint and
maintain the Telecommunication Equipment in such color(s) as Landlord shall
determine and shall install such fencing, screening and other protective
equipment on or about the Telecommunication Equipment as Landlord may reasonably
determine and/or as may be required under any covenants, conditions and
restrictions now or hereafter recorded against the Real Property.

                                      -62-
<PAGE>

          25.30.7 Tenant shall (i) be solely responsible for any damage caused
as a result of the Telecommunication Equipment, (ii) promptly pay any tax,
license or permit fees charged pursuant to any requirements in connection with
the installation, maintenance or use of the Telecommunication Equipment and
comply with all precautions and safeguards recommended by all governmental
authorities, and (iii) make necessary repairs, replacements or maintenance of
the Telecommunication Equipment.

          25.30.8 If any of the conditions set forth in this Section 25.30 are
not complied with by Tenant, then without limiting Landlord's rights and
remedies it may otherwise have under this Lease, Tenant shall correct such
noncompliance within thirty (30) days after receipt of written notice thereof.
If Tenant fails to correct noncompliance within such thirty (30) period, then
Tenant shall immediately discontinue its use of the Telecommunication Equipment
and remove the same.

          25.30.9 Upon the expiration of this Lease or upon any earlier
termination of this Lease, Tenant shall, subject to the control of and direction
from Landlord, remove the Telecommunication Equipment, repair any damage caused
thereby, and restore the roof and other facilities of the Buildings to their
condition existing prior to the installation of the Telecommunication Equipment.

          25.30.10 Tenant's rights under this Section 25.30 shall be personal to
the Original Tenant, any assignee of Tenant (including an Affiliate) to which
Tenant has assigned all of its interests under this Lease pursuant to Article 14
above, and any subtenants of Tenant subleasing portions of the Premises who are
Affiliates of Tenant pursuant to Section 14.7 above. In the event that Tenant
shall seek to allow a subtenant subleasing any portion of the Premises who is
not an Affiliate to use or exercise the rights granted to Tenant hereunder,
Tenant must first obtain Landlord's prior consent thereto, which shall not be
unreasonably withheld or delayed. Notwithstanding anything in this Section 25.30
to the contrary, the rights granted hereunder may only be used in connection
with the use of the Premises by Tenant or any such assignee or approved
subtenant of Tenant permitted by Article 5 above.
