<PAGE>

                            STANDARD LEASE PROVISIONS

ARTICLE 1. PREMISES

            1.1 Lease of Premises. On all of the terms and conditions of this
Lease, Landlord leases to Tenant, and Tenant leases from Landlord, the Premises.
The Building together with the underlying land, landscaping, plaza area, parking
facilities and other improvements are referred to collectively as the "Project."
This Lease consists of the Basic Lease Provisions, the Standard Lease
Provisions, and the Exhibits and/or addenda attached to this Lease. Landlord and
Tenant hereby agree that the Rentable Area of the Building and the Premises set
forth in Items 2 and 3, respectively, of the Basic Lease Provisions shall be
conclusive and binding upon the parties.

ARTICLE 2. TERM

            2.1 Commencement Date. The term shall commence on the earliest of
the following date, which date shall be the "Commencement Date":

                  2.1.1 The Beneficial Occupancy Date (as defined in Section 2.4
below);

                  2.1.2 The date when Tenant enters or occupies the Premises for
any use other than for purposes of construction of improvements or inspection of
the Premises under construction; or

                  2.1.3 The date upon which the parties agree as the
Commencement Date.

            When the Commencement Date is ascertained, the Term shall commence
and Tenant shall execute and deliver to Landlord within ten (10) days after
request therefor a certificate or memorandum confirming the Commencement Date
and the Expiration Date in the form of Exhibit E attached hereto. Tenant also
shall execute and deliver to Landlord a second memorandum in the form of Exhibit
E after the Commencement Date re: Suite 225 is ascertained.

            Landlord shall use diligent efforts to complete the Tenant
Improvements in the Premises as soon as Landlord secures possession of the
Premises. In this respect, Landlord is in the process of negotiating a surrender
agreement with the tenant currently occupying Suite 116. Landlord shall continue
to use commercially reasonable efforts to secure possession of Suite 116 and
Suite 225.

            2.2 Measurement of Lease Term and Expiration Date. The Lease Term is
for the number of years and/or months set forth in the Basic Lease Provisions
measured from the Commencement Date through the Expiration Date. The period from
the Commencement Date through and including the Expiration Date shall be

<PAGE>

referred to as the "Term." If the Term is extended whether by exercise by Tenant
of an option to extend or by other agreement of Landlord and Tenant, the Term,
as so extended, shall from and after the date of exercise of the option to
extend or other agreement be referred to as the "Term," the "Expiration Date"
shall mean the last day of the extended Term, and the original term of this
Lease prior to the extension shall be referred to as the "original Term" or
"initial Term."

            2.3 Estimated Commencement Date. The Basic Lease Provisions contain
an Estimated Commencement Date stating the date on which Landlord reasonably
believes each part of the Premises will be available for beneficial occupancy by
Tenant. Landlord shall use reasonable efforts to make the each part of the
Premises available on the appropriate Estimated Commencement Date; however,
delays or time savings beyond Landlord's control may cause the Commencement Date
with respect to each portion of the Premises to occur on a date other than the
appropriate Estimated Commencement Date. Accordingly, failure of the
Commencement Date to occur on the Estimated Commencement Date shall not affect
the terms, conditions or validity of this Lease, and Landlord shall have no
liability to Tenant based upon the failure of this Lease to commence on the
Estimated Commencement Date.

            Notwithstanding the last sentence of the preceding paragraph, in the
event that Landlord secures possession of Suite 116 on or before June 1, 2000
and the Commencement Date re: Suites 114, 116 and 118 does not occur on or
before October 1, 2000 (subject to extension one day for every day of a force
majeure event or day of Tenant Delay under the Work Letter Agreement), then
Tenant, as its sole and exclusive remedy, shall have the right to terminate this
Lease by written notice to Landlord given at any time before October 10, 2000
(as such date is adjusted in the same manner as the October 1, 2000 date). If
Tenant timely and property terminates this Lease, Landlord shall return to
Tenant all amounts held by Landlord on account of the security deposit and any
prepaid rent and the parties shall thereafter have no remaining obligations to
each other, except for any indemnity obligations which are intended to survive
the termination of this Lease. Similarly, if the Commencement Date re: Suite 225
does not occur within 120 days after the date Landlord secures possession of
Suite 225 (subject to extension one day for every day of a force majeure event
or day of Tenant Delay under the Work Letter Agreement), then Tenant, as its
sole and exclusive remedy, shall have the right to terminate this Lease with
respect to Suite 225 only by written notice to Landlord given at any time before
130 days after the date Landlord secures possession of Suite 225. If Tenant
timely and property terminates this Lease with respect to Suite 225, Landlord
shall return to Tenant any security deposit or prepaid rent held by Landlord on
account of Suite 225 and the parties shall thereafter have no remaining
obligations to each other with respect to Suite 225, except for any indemnity
obligations which are intended to survive the termination of this Lease; this
Lease shall remain in full force and effect with respect to Suites 114, 116 and
118 .

Note to Landlord: If there is a delay in the Commencement Date of the Lease, the
Expiration Date is similarly delayed. In some cases, you may want to the
Expiration Date to remain fixed, notwithstanding a delay in the Commencement
Date. For instance, there may be a commitment to deliver to space as expansion
space to another date on a date in the future.

            2.4 Beneficial Occupancy Date. The Premises shall be deemed
available for beneficial occupancy when all of the following conditions have
been satisfied:

                  2.4.1 Landlord shall have substantially completed all of the
work, if any, required to be performed by Landlord pursuant to any Work Letter
Agreement attached to this Lease as an exhibit; provided, however, that the date
of

<PAGE>

such substantial completion shall be advanced by any period of delay which
Landlord determines has been caused by Tenant (including any delay referred to
in the Work Letter Agreement as Tenant Delay). If no Work Letter Agreement is
attached to this Lease, this condition shall be deemed satisfied; and

                  2.4.2 Any previous tenant or occupants shall have vacated the
Premises.

            The date when the Premises are available for beneficial occupancy
shall be the "Beneficial Occupancy Date."If there is a Scheduled Commencement
Date and no tenant improvements to be constructed, the last sentence of Section
2.4 should be deleted. Section 2.4 should be deleted in its entirety if the
Tenant will construct the tenant improvements, since the concept of operation of
Building systems will ordinarily be addressed in the Work Letter in such cases.

            2.5 Option to Extend.

                  2.5.1 Option to Extend Term and Method of Exercise. Tenant
shall have the right (the "Extension Option"), at its option, to extend the Term
for one (1) period of five (5) years (the "Option Term") immediately following
the expiration of the initial Term. Tenant shall exercise the Extension Option
by delivery of written notice to Landlord at least one hundred eighty (180) days
and no more than three hundred sixty (360) days prior to the then scheduled
Expiration Date of the Term. The Extension Option is personal to the original
Tenant (meaning Software Technologies Corporation) and any Affiliate Entity (as
defined in Section 18.7.3) and may not be exercised or assigned, voluntarily or
involuntarily, by, to or on behalf of any person or entity other than Tenant or
an Affiliate Entity. The Extension Option is not assignable separate and apart
from this Lease or otherwise.

                  2.5.2 Incorporation of Lease by Reference. All of the terms,
covenants and conditions (including without limitation defined terms) contained
in this Lease shall be applicable to the Option Term in the event of exercise by
Tenant; provided, however, that the Term and the Monthly Basic Rent shall be
modified as provided herein and Tenant shall not be entitled to any further
option to extend this Lease, and further provided that Tenant shall have no
early termination right during the Option Term.

                  2.5.3 Rent. Subject to adjustment as hereafter provided, the
Monthly Basic Rent for the Option Term shall be adjusted to the greater of (a)
the Monthly Basic Rent for the last month of the initial Term or (b) the
Prevailing Market Rent, described below.

                  2.5.4 Prevailing Market Rent. The "Prevailing Market Rent"
shall be equal to the rental per square foot of Rentable Area per month as of
the date which is approximately six (6) to nine (9) months prior to the
expiration of the initial Term of the Lease, prevailing for comparable office
space in the Monrovia, California area. In determining the Prevailing Market
Rent, whether for comparable space within the Building or in the Monrovia,
California area, the following factors shall be taken into account:

<PAGE>

                        2.5.4.1 The particular configuration, frontage along a
public thoroughfare, signage visible to the public, parking facilities, and
general level of quality of improvements and location of each comparison
building shall be relevant.

                        2.5.4.2 Charges for parking, if any, shall be taken into
consideration and adjustments shall be made for variations, if any, in charges
paid as additional rent by tenants.

                        2.5.4.3 No rent which has not been set or adjusted
during the twelve month period immediately preceding the Expiration Date of the
initial Term shall be considered prevailing or current.

                        2.5.4.4 Periods of free rent or other rent concessions
shall not be taken in account.

                        2.5.4.5 No deduction, offset or other allowance shall be
made for any tenant improvements or refurbishment allowance; provided, however,
that any improvements, alterations or refurbishments made at Tenant's expense
shall not be taken into consideration.

                  If Tenant has timely exercised the Extension Option, Landlord
shall endeavor to notify Tenant in writing of the proposed new Monthly Basic
Rent determined by Landlord for the Option Term at least ninety (90) days prior
to the Commencement Date of the Option Term. Unless Tenant objects to the amount
determined by Landlord within fifteen (15) business days after receipt of such
notice, the amount stated in such notice shall be the new Monthly Basic Rent. If
Tenant objects to Landlord's proposal, Tenant may withdraw the exercise of the
Extension Option; or, at Tenant's election, the Prevailing Market Rent shall be
determined pursuant to the appraisal procedures set forth in Section 2.5.5 of
this Lease. If the Monthly Basic Rent shall not have been determined by the
Commencement Date of the Option Term, then until it is determined, Tenant shall
pay Monthly Basic Rent when due during the Option Term at a rate equal to the
Monthly Basic Rent for the last month of the initial Term. When the Monthly
Basic Rent for the Option Term is determined, either Tenant shall pay to
Landlord any additional rent due for the months which have elapsed in the Option
Term, or Landlord shall credit any excess payment for the elapsed months to the
next Monthly Basic Rent becoming due.

                  2.5.5 Appraisal. The provisions of this Section 2.5.5 shall
only apply to the determination of the Prevailing Market Rent pursuant to the
appraisal remedy set forth in Section 2.5.4. To determine the Prevailing Market
Rent for the Premises by appraisal, real estate appraiser(s), all of whom shall
be members of the American Institute of Real Estate Appraisers and who have at
least five (5) years experience appraising office space located in the vicinity
of the Premises shall be appointed and shall act in accordance with the
following procedures:

<PAGE>

                        (i) The demand for an appraisal shall be made by one
party giving written notice to the other party, which demand to be effective
must state the name, address and qualifications of an appraiser selected by the
party demanding an appraisal (the "Notifying Party"). Within twenty (20)
business days following the Notifying Party's appraisal demand, the other party
(the "Non-Notifying Party") shall either approve the appraiser selected by the
Notifying Party or select a second properly qualified appraiser by giving
written notice of the name, address and qualification of said appraiser to the
Notifying Party. If the Non-Notifying Party fails to select an appraiser within
the twenty (20) business day period, the appraiser selected by the Notifying
Party shall be deemed selected by both parties and no other appraiser shall be
selected. If two appraisers are selected, they shall select a third
appropriately qualified appraiser with ten (10) days. If the two appraisers fail
to select a third qualified appraiser timely, the third appraiser shall be
appointed by the then presiding judge of the county where the Premises are
located upon application by either party.

                        (ii) If only one appraiser is selected, that appraiser
shall notify the parties in simple letter form of its determination of the
Prevailing Market Rent for the Premises within fifteen (15) days following his
selection, which appraisal shall be conclusively determinative and binding on
the parties as the appraised Prevailing Market Rent.

                        (iii) If multiple appraisers are selected, the
appraisers shall meet not later than ten (10) days following the selection of
the last appraiser. At such meeting the appraisers shall attempt to determine
the Prevailing Market Rent for the Premises as of the Commencement Date of the
Option Term by the agreement of at least two (2) of the appraisers.

                        (iv) If two (2) or more of the appraisers agree on the
Prevailing Market Rent for the Premises at the initial meeting, such agreement
shall be determinative and binding upon the parties hereto and the agreeing
appraisers shall, in simple letter form executed by the agreeing appraisers,
forthwith notify both Landlord and Tenant of the amount set by such agreement.
If multiple appraisers are selected and two (2) appraisers are unable to agree
on the Prevailing Market Rent for the Premises, all appraisers shall submit to
Landlord and Tenant an independent appraisal of the Prevailing Market Rent for
the Premises in simple letter form within twenty (20) days following appointment
of the final appraiser. The parties shall then determine the Prevailing Market
Rent for the Premises by averaging the appraisals; provided that any high or low
appraisal, differing from the middle appraisal by more than ten percent (10%) of
the middle appraisal, shall be disregarded in calculating the average.

                        (v) The appraisers' determination of Prevailing Market
Rent shall be based on the factor set forth in Section 2.5.4.

                        (vi) If only one appraiser is selected, then each party
shall pay one-half of the fees and expenses of that appraiser. If three
appraisers are

<PAGE>

selected, each party shall bear the fees and expenses of the appraiser it
selects and one-half of the fees and expenses of the third appraiser.

                  2.5.6 Effect of Default. If Tenant is in material default or
any event or condition has occurred which after notice or passage of time or
both shall constitute a material default at the time Tenant exercises the
Extension Option, then any attempt to exercise such Extension Option shall be
null, void and of no force or effect. If Tenant exercises the Extension Option
and if Tenant is in material default or any event or condition has occurred
which after notice or passage of time or both shall constitute a material
default during the period between exercise of the Extension Option and the first
day for commencement of the Option Term, then the exercise of such Extension
Option by Tenant shall be null, void and of no force or effect. If Tenant has
been in default in payment of any sum required by this Lease where a late charge
has become due for more than three (3) times during the initial Term, then the
provisions of the Extension Option to extend the Term shall be canceled and
shall be of no force or effect. No condition of the Premises, including without
limitation any alteration or improvement made by Tenant, oral intention
expressed by Tenant or detrimental reliance by Tenant on any statement, act or
omission by Landlord shall vest any additional rights in Tenant beyond those
expressly set forth in this Section 2.5 for exercise of the Extension Option or
to possess the Premises during any period set for extension of the Term or estop
Landlord from eviction of Tenant after the end of the initial Term or give rise
to any equitable defense to such eviction. Tenant hereby waives any and all
equitable remedies with respect to the Extension Option unless Tenant has
complied in all respects with the written notice requirements set forth herein.
The sole and exclusive method for exercise of the Extension Option contained
herein shall be delivery of the written notice called for herein by Tenant to
Landlord on a timely basis. Landlord and Tenant hereby agree that time is of the
essence with respect to delivery of any notice of exercise by Tenant to
Landlord. The date for delivery of any notice required or permitted in the
Extension Option shall be determined by the provisions for delivery of notice
contained in this Lease.

            2.6 Early Entry into Premises. Tenant may enter into the Premises
upon receipt of Landlord's consent (approximately 15 days prior to the
Commencement Date), solely for the purpose of installing furniture, trade
fixtures, cabling, telephones, computers, photocopy equipment, and other
business equipment. Such early entry will not advance the Commencement Date so
long as Tenant does not commence business operations from any part of the
Premises. All of the provisions of this Lease shall apply to Tenant during any
early entry, including Article 14, but excluding the obligation to pay Rent
unless and until Tenant has commenced business operations in the Premises,
whereupon Rent shall commence. Landlord may revoke its permission for Tenant's
early entry if Tenant's activities or workers interfere with the completion of
the Tenant Improvements (as defined in the Tenant Work Letter attached to this
Lease as Exhibit B). If Tenant is granted early entry, Landlord shall not be
responsible for any loss, including theft, damage or destruction to any work or
material installed or stored by Tenant at the Premises or for any injury to
Tenant or its agents, employees, contractors, subcontractors, subtenants,
assigns or invitees (collectively, "Tenant's

<PAGE>

Parties"). Landlord shall have the right to post appropriate notices of
non-responsibility and to require Tenant to provide Landlord with evidence that
Tenant has fulfilled its obligation to provide insurance pursuant to Article 14
of this Lease.Provisions affecting the length of the term, including extension
terms and early termination rights of either Landlord or Tenant, should be added
here as part of Article 2.

            2.7 Right of First Offer.

                  2.7.1 Right; First Offer Space. Landlord grants to Tenant a
right of first offer with respect to any available space in the Building that is
adjacent to the Premises (the "First Offer Space"). Notwithstanding the
foregoing, (i) such first offer right of Tenant shall commence only following
Tenant's written notification to Landlord that Tenant desires to expand its
Premises, (ii) such first offer right of Tenant shall commence only following
the expiration or earlier termination of (A) any existing lease pertaining to
the First Offer Space, and (B) as to any First Offer Space which is vacant as of
the date of this Lease, the first lease pertaining to any portion of such First
Offer Space entered into by Landlord after the date of this Lease (collectively,
the "Superior Leases"), including any renewal of such existing or future lease,
whether or not such renewal is pursuant to an express written provision in such
lease, and regardless of whether any such renewal is consummated pursuant to a
lease amendment or a new lease, and (iii) such first offer right shall be
subordinate and secondary to all rights of expansion, first refusal, first offer
or similar rights granted to (A) the tenants of the Superior Leases and (B) any
other tenant of the Project (the rights described in items (ii) and (iii), above
to be known collectively as "Superior Rights"). Tenant's right of first offer
shall be on the terms and conditions set forth in this Section 2.7.

                  2.7.2 Procedure for Offer. Provided that Tenant's written
notice of its desire to expand has been delivered within the prior three (3)
months, and except as it relates to any Superior Leases, Landlord shall notify
Tenant ("First Offer Notice") when Landlord commences to market the First Offer
Space for lease to third parties. The First Offer Notice shall describe the
space so offered to Tenant and shall set forth Landlord's proposed economic
terms and conditions applicable to Tenant's lease of such space.

                  2.7.3 Procedure for Acceptance. If Tenant wishes to exercise
Tenant's right of first offer with respect to the space described in the First
Offer Notice, then within five (5) business days after delivery of the First
Offer Notice to Tenant, Tenant shall deliver notice to Landlord of Tenant's
unconditional exercise of its right of first offer with respect to the entire
space described in the First Offer Notice in accordance with the terms contained
in the First Offer Notice (the "Exercise Notice"). If Tenant does not deliver
its Exercise Notice (with unconditional acceptance of the terms contained in the
First Offer Notice) to Landlord within the five (5) business day period with
respect to the entire space contained in the First Offer Notice, then Landlord
shall be free to lease the space described in the First Offer Notice to anyone
to whom Landlord desires on substantially the same terms (in all material
respects) offered to Tenant and Tenant's right of first offer shall terminate
with respect to that particular First Offer Space and be of no force or effect.
If Landlord does not

<PAGE>

lease the First Offer Space within 120 days after the expiration the aforesaid
five (5) business day period, then any further attempt by Landlord to lease the
First Offer Space shall again be subject to this Section 2.7. Notwithstanding
anything to the contrary contained herein, (a) Tenant must elect to exercise its
right of first offer, if at all, with respect to all of the space offered by
Landlord to Tenant, and Tenant may not elect to lease only a portion thereof,
and (b) Tenant's rights under this Section 2.7 shall automatically terminate and
be of no force or effect with respect to the subject space being offered if
Tenant does timely and properly deliver its Exercise Notice, and (c) in no event
shall the basic rent for the First Offer Space be less than the then current
Monthly Basic Rent (on a per rentable square foot basis).

                  2.7.4 Lease of First Offer Space. If Tenant timely exercises
Tenant's right to lease the First Offer Space as set forth herein, Landlord and
Tenant shall execute an amendment adding such First Offer Space to this Lease
upon the same non-economic terms and conditions as applicable to the initial
Premises, and the economic terms and conditions as provided in this Section 2.7.
Tenant shall commence payment of rent for the First Offer Space and the Lease
Term of the First Offer Space shall commence upon the date set forth in the
First Offer Notice.

                  2.7.5 No Defaults. The rights contained in this Section 2.7
shall be personal to the original Tenant (meaning Software Technologies
Corporation) and any Affiliate Entity, and may only be exercised by the original
Tenant (and not any assignee, sublessee or other transferee of the original
Tenant's interest in this Lease, except an Affiliate Entity) if Tenant or an
Affiliate Entity (but not both together) occupies (occupy) the entire Premises
as of the date of the First Offer Notice. Tenant shall not have the right to
lease the First Offer Space as provided in this Section 2.7 if, as of the date
of the First Offer Notice or, at Landlord's option, as of the scheduled date of
delivery of such First Offer Space to Tenant, Tenant is in default under this
Lease beyond the expiration of any applicable notice and cure periods or Tenant
has previously been in monetary default under this Lease more than two times.

            2.8 Option to Terminate. Tenant shall have a one-time option (the
"Termination Option") to terminate the Lease effective as of the end of the
thirty-sixth (36th) month of the initial Term (the "Termination Date"), upon the
following terms and conditions:

                  2.8.1 On or before the end of the twenty-seventh (27th) month
of the initial Term, Tenant shall give to Landlord written notice ("Tenant's
Termination Notice") of Tenant's election to exercise the Termination Option;

                  2.8.2 Tenant shall not be in default under this Lease beyond
any applicable cure period either on the date Tenant exercises the Termination
Option, or at any time prior to the Termination Date; and

                  2.8.3 Tenant shall pay to Landlord, concurrently with its
exercise of the Termination Option and delivery of Tenant's Termination Notice,
a

<PAGE>

cancellation premium in an amount equal to the sum of: (i) the unamortized
tenant improvements, brokerage commissions and legal fees with respect to the
Premises, using a ten percent (10%) interest factor; and (ii) five month's Basic
Rent, calculated using the Basic Rent figure in place after the thirtieth (30th)
month of the Term. Within ten (10) business days of Tenant's written request
(which must be submitted no earlier than 45 days before the date Tenant gives
Tenant's Termination Notice), Landlord shall advise Tenant of the amount of the
cancellation premium.

            In the event Tenant timely and properly exercises the Termination
Option, the Term shall terminate effective as of the Termination Date. Rent
(however denominated) shall be paid through and apportioned as of the
Termination Date, and neither Landlord nor Tenant shall have any rights,
estates, liabilities or obligations accruing under the Lease after the
Termination Date, except such rights and liabilities which, by the terms of the
Lease are obligations of Tenant or Landlord which are intended to survive the
expiration of the Lease. The Termination Option shall automatically terminate
and become null and void upon: (a) the failure of Tenant to timely or properly
exercise the Termination Option; or (b) the termination of Tenant's right to
possession of the Premises. Provisions affecting the length of the term,
including extension terms and early termination rights of either Landlord or
Tenant, should be added here as part of Article 2.

ARTICLE 3. TENANT IMPROVEMENTS AND ACCEPTANCE OF PREMISES.

            Landlord's sole obligation respecting Tenant improvements shall be
to perform the work described as Landlord's work in any Work Letter Agreement
attached to this Lease as Exhibit B. By taking possession of the Premises,
Tenant shall have acknowledged that (i) it has inspected the Premises, (ii) it
accepts the Premises, (iii) the Premises are in good and sanitary order, and
(iv) all work to be performed by Landlord has been satisfactorily completed
except for those minor items which Landlord and Tenant shall agree require
further completion and which items shall be incorporated into a punch list
executed by Landlord and Tenant prior to the date of delivery of possession to
Tenant. Landlord shall use reasonable efforts to cause the items listed on the
punch list to be completed within a reasonable time. Neither Landlord nor any
agent of Landlord has made any promise, representation or warranty respecting
the Premises, the Building or the Project, or their suitability for the conduct
of Tenant's business unless otherwise set forth in this Lease or its exhibits,
and any statement which may have been made by Landlord or any agent of Landlord
is expressly disclaimed and is not being relied upon by Tenant.

            Notwithstanding the foregoing, Landlord represents, to the best of
its property manager's actual knowledge, that Landlord has not received any
written notice that the Project or the Premises is not in material compliance
with all municipal ordinances and state and federal laws and statutes (including
without limitation, Title 24 of the California Administrative Code) and all
rules and regulations of duly constituted public authorities having jurisdiction
over the Project and the Premises. Landlord further represents that as of the
Commencement Date: (i) the Premises will be in broom clean condition; (ii) the
electrical, mechanical, HVAC, plumbing, elevator and sewer serving the Premises
will be in good operating condition and repair; and (iii) the roof of the
Building will be in good condition and water tight. If a breach of the

<PAGE>

foregoing representations of Landlord exists, then Tenant shall deliver written
notice to Landlord setting forth in reasonable detail a description of such
breach within ninety (90) days following the Commencement Date, and Landlord
shall, as Tenant's sole and exclusive remedy, rectify the same at Landlord's
expense; provided, however, that Landlord's obligation hereunder shall only be
applicable if (a) Tenant timely (i.e., within 90 days of the Commencement Date
of this Lease) delivers the detailed notice of such breach to Landlord as
described above, (b) such non-compliance does, in fact, constitute a breach of
the foregoing representations, and (c) with respect only to the representation
of Landlord set forth in the first sentence of this paragraph and not to the
representations in the succeeding sentences, such non-compliance is required to
be rectified by a governmental authority with jurisdiction over the Building.
Landlord shall have no obligation to rectify any breach of any of the foregoing
representations if the breach of the representation at issue results from the
actions or inactions of Tenant, its agents, representaives, contractors,
customers, invitees or licensees.

ARTICLE 4. RENT.

            4.1 Basic Rent. Tenant shall pay to Landlord the Monthly Basic Rent
for the Premises set forth in the Basic Lease Provisions. Tenant's obligation to
pay rent shall begin on the Commencement Date and shall continue through the
expiration or earlier termination of the Lease. The Monthly Basic Rent shall be
paid in advance on or before the first day of each calendar month during the
Term; for any partial month, rent shall be prorated based on the actual number
of days in the month and shall be payable in advance. The rent payable for the
first month of the Term shall be payable upon execution of this Lease by Tenant.
Rent shall be payable without notice, demand, reduction or set-off in lawful
money of the United States of America to Landlord or its agent at the address
set forth in the Basic Lease Provisions, or to such other person or such other
place as Landlord may from time to time notify Tenant.

            4.2 Adjustment to Annual Basic Rent. Intentionally Omitted.

            4.3 Late Charges. If Tenant fails to pay any installment of rent or
other payment due under this Lease within five (5) days after the date due,
Tenant shall pay to Landlord a late charge equal to five percent (5%) of the
amount due plus any attorneys' fees incurred by Landlord by reason of Tenant's
failure to pay rent or any other charges when due hereunder to compensate
Landlord for the extra cost incurred as a result of such late payment. The
parties agree that the late charge represents a fair and reasonable estimate of
the administrative, processing and accounting costs that Landlord will incur as
a result of a late payment by Tenant. The late charge shall be deemed to be
rent, and the right to require it shall be in addition to all of Landlord's
other rights and remedies for a payment failure of Tenant, including the right
to charge interest on the past due amount.

<PAGE>

ARTICLE 5. ADDITIONAL RENT.

            5.1 Obligations to Pay Additional Rent.

                  5.1.1 Tenant's Share. In addition to the Monthly Basic Rent
and other sums to be paid by Tenant to Landlord, Tenant shall pay to Landlord as
additional rent the amount by which Tenant's share of Operating Expenses
(defined below) for any calendar year or part thereof during the Term exceeds
Tenant's Operating Expense Base Amount (defined below).

                  5.1.2 Tenant's Operating Expense Base Amount. If an Expense
Stop Base is set forth in the Basic Lease Provisions, Tenant's Operating Expense
Base Amount shall be equal to such amount multiplied by the Rentable Area of the
Premises, and if instead a Base Year is set forth in the Basic Lease Provisions,
Tenant's Operating Expense Base Amount shall be equal to Tenant's Building
Expense Percentage of the Operating Expenses for the Base Year. Tenant's share
of Operating Expenses shall be an amount equal to the product of the Operating
Expenses multiplied by Tenant's Building Expense Percentage. If any part of the
Term begins or ends on any day other than the first or last day of a calendar
year, respectively, the annual Operating Expenses and the Tenant's Operating
Expense Base Amount shall be prorated for such partial year on a daily basis
using a 30 day month and 360 day year to determine the amount of additional rent
due to Landlord. If a Base Year is set forth in the Basic Lease Provisions, the
following additional provisions shall be applicable: (a) Tenant's Operating
Expense Base Amount shall be determined on one occasion only in conjunction with
Landlord's annual statement of Operating Expenses for the Base Year issued to
Tenant pursuant to Section 5.2 of this Lease; (b) any challenge by Tenant to
Landlord's determination of Tenant's Operating Expense Base Amount must be made
within the time period set forth in Section 5.2 of this Lease for challenging
the annual statement of Operating Expenses for the Base Year; and (c) once
Tenant's Operating Expense Base Amount has been so determined, (1) the
determination shall be final and conclusive upon Landlord and Tenant, and (2)
Landlord and Tenant will promptly following the request of either party execute
an amendment to this Lease setting forth Tenant's Operating Expense Base Amount,
although any failure to execute any such amendment shall not affect the
determination of Tenant's Operating Expense Base Amount or Landlord's right to
collect additional rent in accordance with this Article 5.

                  5.1.3 Estimated Operating Expenses. Landlord may make a
reasonable estimate of Operating Expenses projected for each calendar year and
may revise such estimates no more than two (2) times during the calendar year.
If Landlord notifies Tenant that Landlord's estimate (or any revised estimate)
of Operating Expenses would result in an obligation of Tenant to pay additional
rent, then upon request by Landlord, Tenant shall pay one-twelfth (1/12) of such
estimated additional rent on the first day of each month together with the
Monthly Basic Rent. If Landlord so notifies Tenant after the commencement of a
calendar year, then with the next

<PAGE>

payment of Monthly Basic Rent due, Tenant shall also pay to Landlord one-twelfth
(1/12) of such estimated additional rent for each month of such calendar year
which has already elapsed.

            5.2 Annual Statement.

                  5.2.1 Delivery of Annual Statement. Landlord shall provide
Tenant with an annual statement showing Tenant's share of the annual Operating
Expenses for the prior calendar year. Landlord shall use reasonable efforts to
deliver the annual statement within one hundred twenty (120) days after the end
of the calendar year; however, the failure of Landlord to deliver the annual
statement within such period shall not impair or constitute waiver of Tenant's
obligations to pay additional rent or cause Landlord to incur any obligation for
damages. If the additional rent due for the calendar year exceeds any amounts
paid by Tenant as estimated additional rent for such calendar year, Tenant shall
pay such excess to Landlord within twenty (20) days of receipt of Landlord's
statement. If the estimated additional rent paid for a calendar year exceeds
Tenant's obligation shown on the annual statement, Tenant shall receive a credit
against monthly installments of rent next coming due. If no further sums of rent
are or will become due against which the excess can be credited, then, subject
to offset at Landlord's election against other sums owed by Tenant, Landlord
shall pay such excess to Tenant within twenty (20) days after delivery of the
annual statement. If Landlord has not required Tenant to pay installments of
estimated additional rent, Tenant shall pay Landlord any sum of additional rent
due within twenty (20) days after delivery of any statement by Landlord
reflecting the amount of overall additional rent. All obligations to pay
additional rent and/or the obligation of Landlord to credit or reimburse Tenant
for any excess payment of estimated additional rent shall survive the
termination of this Lease.

                  5.2.2 Tenant's Limited Right to Dispute Annual Statement.
Tenant's sole right to challenge, question, dispute or otherwise object to the
amount of Tenant's additional rent due under this Article 5 for a calendar year
or portion thereof during the Term shall be as set forth in this Section 5.2.2.
In order to question, challenge, dispute or otherwise object to the amount shown
on the annual statement as the annual Operating Expenses, any particular amount
or component thereof, Tenant's additional rent or any other thing or matter
relating thereto, Tenant must (a) not be in default beyond any applicable notice
and cure periods under any of the terms of this Lease, and (b) deliver to
Landlord on or before sixty (60) days after delivery to Tenant of the annual
statement of Operating Expenses (the "Objection Period") notice specifying the
items which are challenged, questioned or disputed (an "Objection Notice").
Except for those issues raised in an Objection Notice delivered to Landlord on
or before expiration of the Objection Period, Tenant waives and relinquishes the
right to question, challenge, dispute or otherwise object to the amount shown on
the annual statement as the annual Operating Expenses, any particular amount or
component thereof, Tenant's additional rent or any other thing or matter
relating thereto at any time after expiration of the Objection Period. If Tenant
timely delivers an Objection Notice, Tenant shall then have a period of sixty
(60) days (the "Inspection

<PAGE>

Period") in which to have an inspection of Landlord's records relating to the
issues raised in the Objection Notice conducted by a Qualified Person (as
defined below) during business hours upon reasonable notice to Landlord;
provided, however, that Landlord may refuse to permit Tenant to inspect any
records containing details of employee compensation or other information
considered by Landlord to be confidential or proprietary in nature, and Landlord
may instead provide to Tenant such certifications regarding the amounts
contained therein as Landlord shall deem appropriate under the circumstances. If
Tenant has conducted an inspection of Landlord's records relating to the issues
raised in the Objection Notice by a Qualified Person, Tenant may on or before
expiration of the Inspection Period deliver notice to Landlord of any issues set
forth in the Objection Notice which Tenant continues to challenge (the
"Challenge Notice"), in which case a certification as to proper amount shall be
made, at Tenant's expense, by Landlord's independent certified public
accountant, which certification shall be final and conclusive. If on or before
expiration of the Inspection Period, Tenant fails either to conduct an
inspection of the records or to deliver a Challenge Notice to Landlord, Tenant
shall be deemed to have waived its objections raised in the Objection Notice and
shall have no further right to question, challenge, dispute or object to the
amount shown on the annual statement as the annual Operating Expenses, any
particular amount or component thereof, Tenant's additional rent or any other
thing or matter relating thereto. A "Qualified Person" means an accountant or
other person experienced in accounting for income and expenses of office
buildings engaged solely by Tenant on terms which do not entail any compensation
based or measured in any way upon any savings in additional rent or reduction in
Operating Expenses achieved through the inspection process. Notwithstanding any
question, dispute, challenge or objection of Tenant, Tenant shall pay the amount
claimed by Landlord to be due as and when provided for in this Article 5,
pending the resolution of Tenant's question, challenge, dispute or objection,
and Tenant waives any right it may otherwise have to raise the existence of any
such question, challenge, dispute or objection as a defense to its payment
obligation. If the audit by the independent certified public accountant shows
that Operating Expenses are overstated by more than five percent (5%), then
Landlord agrees to pay the costs of such audit, not to exceed Five Thousand and
00/100 Dollars ($5,000.00) per audit. If the audit reveals that Tenant has
overpaid Operating Expenses, Landlord shall reimburse to Tenant within thirty
(30) days following Landlord's receipt of the audit results the amount of
Operating Expenses which Tenant has overpaid. If the audit reveals that Tenant
has underpaid Operating Expenses, Tenant shall pay to Landlord within thirty
(30) days following Tenant's receipt of the audit results the amount of
Operating Expenses which Tenant has underpaid.

                  5.2.3 Confidentiality. Tenant shall keep strictly confidential
and shall cause the Qualified Person inspecting Landlord's records on behalf of
Tenant to keep strictly confidential the information in Landlord's records, any
compilations, comparisons, summaries or other work product prepared by Tenant or
such persons based upon any inspection of Landlord's records and any adjustments
to Operating Expenses or Tenant's share of Operating Expenses made by Landlord
based upon any such inspection and any discussions or negotiations between
Landlord and Tenant

<PAGE>

regarding same. The information in Landlord's records and any compilations,
comparisons, summaries or other work product prepared by or for Tenant based
thereon shall be used solely for the purpose of evaluating the accuracy of the
annual statement of Operating Expenses. Tenant shall deliver to Landlord copies
of any such compilations, comparisons, summaries or other work product within
five (5) business days after delivery to Tenant of Landlord's request therefor.
As a condition upon Tenant's right to make an inspection, Landlord may require
that Tenant and its Qualified Person execute a separate confidentiality
agreement in favor of Landlord reflecting the foregoing, but the confidentiality
requirements set forth above shall be binding upon Tenant, whether a separate
confidentiality agreement is required.

            5.3 Operating Expenses.

                  5.3.1 Definition. Subject to the adjustments set forth in
Section 5.3.2 and the exclusions set forth in Section 5.3.3, "Operating
Expenses" of the Project mean all costs and expenses paid or incurred by
Landlord in connection with the ownership, operation, management, security,
maintenance, repair, replacement and restoration of the Project, including the
parking facilities and Common Areas. Without limiting the generality of the
foregoing, Operating Expenses include the following:

                        5.3.1.1 All costs and expenses of utilities furnished to
the Project including all costs and expenses attributable to supply of
electrical service, water and sewage service, natural gas, cable television or
other electronic or microwave signal reception, telephone service or other
communication, steam, heat, cooling or any other service which is now or in the
future considered a utility furnished to the Project (collectively, the "Utility
Services").

                        5.3.1.2 All real property taxes (collectively, "Tax
Expenses") which shall include (i) any form of tax or assessment, license fee,
license tax, tax or excise on rent or any other levy, charge, expense or
imposition made or required by any governmental authority on any interest of
Landlord and/or Tenant in the Premises, the Building or the remainder of the
Project, including the underlying real property and appurtenances; (ii) any fee
for services charged by any governmental agency or quasi-governmental agency for
any services such as fire protection, street, sidewalk and road maintenance,
refuse collection, school systems or other services provided or formerly
provided to property owners and residents within the general area of the Project
at no cost or minimal cost; (iii) any governmental impositions allocable to or
measured by the area of the Premises or the amount of any rent payable under
this Lease, including any tax on gross receipts or any excise tax or other
charges levied by any governmental authority on rent or the possession, leasing,
operation, maintenance, alteration, repair, use or occupancy of the Premises;
(iv) any impositions by any governmental authority of a recurring nature on this
Lease transaction; (v) any personal property taxes imposed upon the fixtures,
machinery, equipment, apparatus, systems and equipment, appurtenances, furniture
and other personal property used in connection with the Project or any portion
thereof; (vi) any costs and expenses (including, without limitation, reasonable
attorneys' fees) incurred in attempting to

<PAGE>

protest, reduce or minimize Tax Expenses; and (vii) any increase in any of the
foregoing based upon construction of improvements on the Project or changes in
ownership (as defined in the California Revenue and Taxation Code) of the
Project. If the Tax Expenses payable on the Project for any year are calculated
on a value which is less than the assessed value of the Project and are
therefore less than the amount which would have been charged on the full
assessed value, the Tax Expenses included in Operating Expenses for such year
shall be equal to such reduced amount. Tax Expenses shall not include taxes on
the Landlord's net income including state franchise taxes or any inheritance,
estate, transfer or gift taxes. Tax Expenses also shall not include and Tenant
shall not be required to pay any tax or assessment expense or any increase
therein (i) levied on Landlord's rental income, unless such tax or assessment
expense is imposed in lieu of real property taxes; or (ii) in excess of the
amount which would be payable if such tax or assessment expense were paid in
installments over the longest possible term.

                        5.3.1.3 All costs and expenses of (a) insurance obtained
by Landlord (including public liability, contractual liability, property damage,
fire and extended coverage, sprinkler damage, theft, malicious mischief and
vandalism, flood, rental loss, rent continuation, boiler and machinery, business
interruption, earthquake, all risk coverage, and other coverages in such amounts
as Landlord determines appropriate to carry in connection with ownership and
operation of an office building in Los Angeles County, California, or such other
insurance as may be required by any present or future lender on loans secured by
the Project); (b) labor and supplies; (c) license, permit, inspection fees and
other fees of governmental authorities; (d) all assessments and special
assessments due to deed restrictions, declarations and/or owners associations
which accrue against the Project; (e) the cost of compensation (including
employment taxes, similar governmental charges and fringe benefits) with respect
to all persons who perform duties in connection with management, operation,
repair, landscaping, janitorial, painting, window washing and general cleaning
services, security services and any other services related to the operation,
maintenance or repair of the Project, whether employed by Landlord, Landlord's
property manager or a third party; provided, however, that if any person
employed at the Project also performs services at other projects of Landlord or
Landlord's property manager, the costs of compensation of such person and
related payroll expenses shall be proportionately allocated in the manner
determined by Landlord between the Project and such other projects; (f) the cost
of all tools and other equipment used in the cleaning, management, operation,
security, maintenance and repair of the Project; (g) all costs of repainting and
replacement of floor and wall coverings, walkways, ceiling tiles and fixtures in
lobbies, corridors, restrooms, parking facilities and other Common Areas of the
Project; (h) the costs of the following amortized (with interest) on a straight
line basis in accordance with generally accepted accounting principles ("GAAP):
(1) all personal property equipment not described in (f) above, (2) signs
installed by Landlord, (3) the cost of all capital improvements that have a
useful life of five (5) years or less, (4) costs and expenses of a capital
nature, including costs and expenses of additions to or replacements of
equipment or existing improvements, made to the Project for the purposes of
reducing Operating Expenses or pursuant to the

<PAGE>

requirements of any governmental authority made applicable to or first enforced
against the Project after the date of this Lease, and (5) any other costs and
expenses otherwise includable in Operating Expenses which Landlord in its sole
discretion determines it is appropriate to amortize; (i) costs of clean-up and
removal of Hazardous Materials (as hereafter defined) and any fines and
penalties imposed by reason of the existence of Hazardous Materials on, in or
about the Project; (j) any costs and expenses described in (a) through (i) above
incurred in connection with Utility Services; and (k) the fair market rental
value of the Project management office, management fees, legal expenses and
accounting expenses. Interest on amortized costs and expenses shall be
calculated at the interest rate which would be payable on past due sums payable
by Tenant under this Lease at the time such costs and expenses are paid by
Landlord.

                  5.3.2 Gross-Up. If the Building is not at least 95% occupied
during any part of any calendar year, then for purposes of determining Operating
Expenses for such calendar year, Landlord shall increase those costs included in
Operating Expenses which vary based upon the level of occupancy of the Building
to the amount of cost which in Landlord's reasonable judgment would have been
incurred if the Building had been 95% occupied for the entire calendar year. The
Operating Expenses for the Base Year shall at Landlord's option not include (a)
any increases in expenses over previous years attributable to extraordinary
circumstances arising during the Base Year and not likely to have a continuing
effect beyond the Base Year, and (b) the amortized cost of any particular
expenditure paid or incurred during or prior to the Base Year otherwise
includable in Operating Expenses for the Base Year under Section 5.3.1.3(h)(4)
above, provided that if Landlord excludes a particular amortized expenditure
from Operating Expenses for the Base Year, Landlord shall not include the
amortized cost of such particular expenditure in the Operating Expenses for any
subsequent calendar year. If no Base Year is set forth in the Basic Lease
Provisions, the foregoing sentence shall not be applicable.

                  5.3.3 Exclusions from Operating Expenses. Notwithstanding

                        5.3.3.3 Costs incurred by Landlord for the repair of

                        5.3.3.25 Costs associated with the operation of the

accounting and legal matters, costs of defending any lawsuits with any mortgagee
(except as the actions of Tenant may be in issue), costs of selling,

                        5.3.3.26 Costs incurred to remove, remedy, contain, or

Landlord's general or net income (as opposed to rents or receipts).

            5.4 If in any calendar year subsequent to the Base Year (the
"Adjustment Year"), the amount of Tax Expenses decreases below the amount of Tax
Expenses for the Base Year as a result of a Proposition 8 reduction, then for
purposes of all subsequent calendar years, including the calendar year in which
such decrease in Tax Expenses occurs, Tenant's Operating Expense Base Amount
shall be decreased by an amount equal to such decrease in Tax Expenses in the
Adjustment Year. Conversely, if the Tax Expenses thereafter are decreased by a
lesser amount during any comparison year subsequent to the Adjustment Year (the
"Readjustment Year") as a result of Landlord's failure to secure a Proposition 8
reduction which is greater than or equal to the Proposition 8 reduction secured
during the Adjustment Year, then for purposes of all subsequent comparison
years,, including the comparison year in which such lesser decrease in Tax
Expenses occurs, Tenant's Operating Expense Base Amount shall only be decreased
by an amount equal to the decrease in Tax Expenses during such Readjustment Year
which resulted from Landlord's failure to secure a Proposition 8 reduction
greater than or equal to the Proposition 8 reduction secured during the
Adjustment Year; provided that any costs and expenses incurred by Landlord in
securing any Proposition 8 reduction shall not be included in Operating Expenses
for purposes of this Lease. Landlord and Tenant acknowledge that this Section
5.4 is not intended to in any way affect (A) the inclusion in Tax Expenses of

<PAGE>

the statutory two percent (2.0%) annual increase in Tax Expenses (as such
statutory increase may be modified by subsequent legislation), or (B) the
inclusion or exclusion of Tax Expenses pursuant to the terms of Proposition 13.
Notwithstanding the foregoing, upon a "Reassessment," as that term is defined
below, which reduces the amount of Tax Expenses, the component of Tax Expenses
for the Base Year which is attributable to the assessed value of the Project
under Proposition 13 prior to the Reassessment (without taking into account any
Proposition 8 reductions) shall be reduced for purposes of comparison to all
subsequent Expense Years (commencing with the calendar year in which the
Reassessment takes place) to an amount equal to the real estate taxes based upon
such Reassessment. A "Reassessment" shall mean the consummation of any sale,
refinancing, or change in ownership of the Building to the extent that in
connection therewith and as a result thereof, the Building is reassessed for
real estate tax purposes by the appropriate governmental authority pursuant to
the terms of Proposition 13 (as adopted by the voters of the State of California
in the June 1978 election).

            5.5 Taxes on Tenant's Personal Property. Before delinquency, Tenant
shall pay all taxes levied against any personal property located in or about the
Premises. If any taxes on Tenant's personal property are levied against Landlord
or Landlord's property or if the assessed value of the Project is increased by
the value of such personal property, Tenant shall pay to Landlord the amount of
such taxes within twenty (20) days after delivery of notice of such amount by
Landlord.

            5.6 Excess Taxes on Tenant Improvements. If the Tenant Improvements
in the Premises, whether installed and/or paid for by Landlord or Tenant, are
assessed for real property tax purposes at a valuation higher than the valuation
at which building standard tenant improvements are assessed, the real property
taxes levied against the Project by reason of such excess assessed valuation as
reasonably determined by Landlord may at Landlord's option be deemed to be taxes
levied against Tenant's personal property governed by Section 5.5.

<PAGE>

ARTICLE 6. SECURITY DEPOSIT.

            Concurrently with the execution of this Lease, Tenant shall deposit
with Landlord the Security Deposit in the amount set forth in the Basic Lease
Provisions as security for the payment and performance of Tenant's obligations
under this Lease. If Tenant performs all of its obligations under this Lease and
pays all sums due Landlord, Landlord shall return the Security Deposit, or
balance thereof then held by Landlord, without interest, to Tenant within two
weeks after Landlord recovers and accepts possession of the Premises. If Tenant
defaults, Landlord may, after the expiration of any applicable notice and cure
period, at its option and without notice, apply all or any part of the Security
Deposit in payment of rent or to cure any other default. If Landlord does so,
Tenant shall, upon notice of such application, deposit with Landlord the amount
so applied so that Landlord will have on hand at all times during the Term the
full Security Deposit. Landlord shall not be required to pay interest on the
Security Deposit to Tenant or to hold the Security Deposit as a separate
account, but may commingle it with Landlord's other funds. In the event of a
sale or other disposition of the Premises, Landlord shall transfer the Security
Deposit to the new owner and deliver to Tenant the notice required by Section
1950.7 of the Civil Code of California; in addition, the new owner shall assume
Landlord's liability with respect to the Security Deposit. Thereafter, Landlord
shall be released by Tenant from all responsibility for returning the Security
Deposit, and Tenant shall look solely to the new owner for return of the
Security Deposit. If Tenant assigns this Lease, Tenant's rights in the Security
Deposit shall be deemed to be assigned to the assignee, such Security Deposit
shall be held by Landlord as a Security Deposit made by the assignee and
Landlord shall have no further responsibility for return of the Security Deposit
to Tenant.

<PAGE>

ARTICLE 7. USE.

            7.1 Use in General. Tenant may use the Premises for the use set
forth in the Basic Lease Provisions, subject to the limitations set forth
elsewhere in this Lease, and shall not use or permit the Premises to be used for
any other purpose without Landlord's prior written permission, which Landlord
may give, deny or condition in Landlord's sole and absolute discretion. Tenant
is not granted the exclusive right to such use in the Project. Tenant shall not
use or occupy the Premises in violation of law. Upon notice from Landlord,
Tenant shall discontinue any use of the Premises declared by any governmental
authority to be a violation of law. Tenant shall comply with any direction of
any governmental authority which shall, by reason of the nature of Tenant's use
or occupancy of the Premises, impose any duty upon Tenant or Landlord respecting
the Premises or use or occupation thereof. Tenant shall comply with all recorded
covenants, conditions and restrictions now or hereafter affecting the Project.
Tenant shall not do or permit to be done anything which will invalidate or
increase the cost of any insurance covering the Project and/or property located
therein and shall comply with all requirements of any fire rating bureau or any
other organization performing a similar function. Tenant shall promptly, upon
demand, reimburse Landlord for any additional premium charged for any insurance
policy by reason of Tenant's failure to comply with the provisions of this
Article. If Landlord requests Tenant to designate fire wardens or other
responsible persons from among the persons regularly located at the Premises,
Tenant shall make such persons available at reasonable times for training,
briefing and drills. Additionally, Tenant shall not (a) do or permit anything to
be done in or about the Premises which will in any way obstruct or interfere
with the rights of other tenants or occupants of the Building or injure or annoy
them, (b) use or allow the Premises to be used for any improper, immoral,
unlawful or objectionable purpose, (c) cause, maintain or permit any nuisance
in, on or about the Premises, (d) commit or permit any waste in or upon the
Premises, or (e) do anything or permit anything to be done in or about the
Premises which is inconsistent with the operation of a first-class building.
Tenant shall not be required to comply with any rule or regulation unless the
same applies non-discriminatorily to all occupants of the Project, does not
unreasonably interfere with Tenant's use of, access to or parking at the
Premises, and does not materially increase the obligations or decrease the
rights of Tenant under the Lease. Tenant shall have access to the Premises
twenty-four (24) hours a day, three hundred sixty-five (365) days a year.

<PAGE>

            7.2 Conduct of Business by Tenant. Tenant shall not use any portion
of the Premises for: (a) product display activities (such as those of a
manufacturer's representative) other than those that are ancillary to office use
or other uses specifically permitted hereunder; (b) offices of agencies of
foreign governments or political subdivisions thereof; (c) any local, state or

ancillary to office use or other uses specifically permitted hereunder; (g)
clerical support services other than those which are ancillary to an otherwise
permitted use; (h) "executive suite" type uses where office suites are
maintained for individual rental with common services provided by Tenant or a

or restaurant areas other than an executive or employee dining room facility
otherwise permitted by this Lease to provide service to persons occupying the
Premises for an otherwise permitted use; (k) communications firms such as radio
or television studios, or (l) personnel agencies.

            7.3 Hazardous Materials.

                  7.3.1 Restrictions on Use. Tenant shall not (a) use, store,
treat or dispose of any Hazardous Material (defined hereafter) on, under or at
the Premises or the Project, except for the lawful use, storage and disposal of
de minimis quantities of Hazardous Material contained in office supplies
typically in use in similar offices; or (b) cause or allow any material with
asbestos, polychlorinated biphenyls (PCBs) or formaldehyde or other Hazardous
Materials to be incorporated into any improvements or alterations which it makes
or causes to be made to the Premises. Tenant shall not take any remedial action
related to Hazardous Materials located in or about the Premises or the Project
and shall not enter into a settlement, consent decree or compromise in response
to any claim related to Hazardous Materials without first notifying Landlord in
writing of Tenant's proposed action and affording Landlord a reasonable
opportunity to appear, intervene or otherwise participate in any discussion or
proceeding for the purposes of protecting Landlord's interest in the Premises
and the Project.

                  7.3.2 Notification. Tenant shall immediately notify Landlord
in writing of: (i) any governmental action instituted or threatened with regard
to Hazardous Materials involving the Premises or the Project; (ii) any claim
made or threatened by any person against Tenant, Landlord, the Premises or the
Project related to any Hazardous Materials; (iii) any reports made to any
environmental agency arising out of or in connection with any Hazardous
Materials at or removed from the Premises or the Project; and (iv) any release
of Hazardous Materials that occurs on or from the Premises.

<PAGE>

                  7.3.3 Definition. "Hazardous Material" means any hazardous,
harmful, odorous, radioactive, toxic or dangerous waste, substance or material,
including any hazardous or toxic substance or waste or any pollutant or
contaminant defined as such in (or for purposes of) any environmental laws as
are now or at any time hereafter may be in effect, and asbestos, polychlorinated
biphenyls, formaldehyde and hydrocarbons. This Section shall extend to Tenant's
use, storage, treatment and disposal of any and all such Hazardous Materials
whether such substance was defined, recognized or known or suspected of being
hazardous, toxic, dangerous or wasteful at the time of any act or omission by
Tenant in violation of this Lease.

                  7.3.4 Tenant Not Responsible. Under no circumstance shall
Tenant be liable for any Hazardous Material present at any time in, on or about
the Building, the Project, or the soil, air, improvements, groundwater or
surface water thereof, or the violation of any environmental law, except if any
of the foregoing results from the acts or omissions of Tenant or its agents,
contractors, guests, invitees, employees, stockholders, directors, successors,
representatives and assigns.

<PAGE>

ARTICLE 8. CONDITION OF PREMISES.

            8.1 Tenant's Obligations to Maintain. Tenant shall, at Tenant's sole
cost, keep the Premises in good, clean and sanitary order and make any necessary
repairs to keep and maintain the Premises in substantially the same condition as
on the Commencement Date, subject to any permitted alterations and ordinary wear
and tear, including the repair or restoration of any damage however caused.
Tenant shall reimburse Landlord for the cost of any repair to the Project
required as a result of any misuse or neglect committed or permitted by Tenant
or by any subtenant, agent, employee or contractor of Tenant; provided, however,
if the cost paid by Tenant exceeds the applicable deductible amount on any
property insurance maintained by Landlord and Landlord is able to collect such
excess from its insurer, Landlord shall reimburse such excess amount, less costs
of collection, to Tenant. If Tenant does not make repairs promptly and
adequately or fails to maintain the Premises as required by this Section within
ten (10) days after delivery of notice of any deficiency by Landlord [or if such
deficiency cannot be reasonably corrected within ten (10) days and Tenant shall
not commence to correct such deficiency within such ten (10) day period and
diligently pursue completion of such correction], then in addition to any other
rights and remedies of Landlord, Landlord may, but shall not be required to,
perform such repairs or maintenance, and any amounts expended by Landlord shall
be reimbursed by Tenant to Landlord together with a 10% overhead charge upon
demand; provided, however, that if in Landlord's judgment, there is an
emergency, Landlord may perform the repairs prior to delivery of notice to
Tenant or expiration of Tenant's cure period. Performance of the repairs or
maintenance work by Landlord shall not cure Tenant's default. If Landlord
performs such repairs or maintenance on Tenant's behalf, Landlord shall not be
liable to Tenant for any loss or damage that may accrue to Tenant's business,
personal property, trade fixtures and/or records and data resulting from such
repair or maintenance. Entry by Landlord to pursue repair or maintenance shall
not be deemed an actual or constructive eviction and shall not entitle Tenant to
any abatement or reduction of rent. Tenant shall notify Landlord in writing
promptly upon discovery of any damage, defect or malfunction of any structural
or mechanical portions of the Building which Landlord is required to repair and
maintain pursuant to Article 9 of this Lease. For purposes of establishing under
this Lease the respective rights and obligations of Landlord and Tenant for
maintenance, repair, restoration and replacement, the Premises shall be deemed
to include the following (collectively, the "Interior Improvements"): the inside
faces of perimeter walls, demising walls and column covers, including in each
case the drywall; all paint and wall coverings; rubber bases; all carpet and
floor coverings; ceiling grid system and ceiling tiles; all interior partitions;
all cabinets and wood work; work stations; plumbing fixtures (other than those
in the restrooms included in the base, shell and core of the Building); kitchen
appliances and other tenant improvements not a part of the base, shell and core
of the Building.

            8.2 Condition Upon Surrender. Upon expiration or earlier termination
of this Lease, Tenant at its cost shall remove from the Premises all

<PAGE>

movable furniture and movable personal property and promptly repair any damage
to the Premises or the Project caused by such removal. Tenant shall not remove
any wall covering, floor covering, shelving, cabinet units (whether for storage,
for library purposes or for any other purpose), or other improvements affixed to
the Premises, whether installed by Landlord or Tenant at its expense and whether
as part of the Tenant Improvements or alterations made by Tenant with or without
Landlord's consent, unless requested to do so by Landlord. At any time within
fifteen (15) days prior to expiration of the scheduled Term, or within a
reasonable time promptly after any other termination of this Lease, Landlord may
demand that Tenant remove from the Premises any alterations, additions,
improvements, fixtures, equipment, shelving, cabinet units or other personal
property designated by Landlord to be removed; provided, however, that Landlord
cannot require Tenant to remove the initial Tenant Improvements, unless Landlord
reserved the right to require such removal at the time of its approval of the
installation thereof. In such event Tenant shall complete such removal
(including the repair of any damage caused by such removal) entirely at its own
expense and within fifteen (15) days of Landlord's demand. All repairs required
by Tenant in this Section shall be performed in a manner satisfactory to
Landlord, and shall include the following: cap all plumbing, cap all electrical
wiring, repair all holes in walls, restore damage to the floors and/or ceiling,
repair any other cosmetic damage, and clean the Premises. If Tenant fails to
remove from the Premises all of its personal property (together with any other
items requested by Landlord to be removed in accordance with this Section) prior
to the expiration or earlier termination of this Lease, Landlord may, at its
option, (i) treat Tenant as a holdover in which event Article 24 of this Lease
shall apply or (ii) handle the items in accordance with applicable laws.

            Unless Landlord demands otherwise, upon expiration of the Term,
Tenant shall surrender to Landlord the Premises in the same condition as the
Premises were upon delivery of possession to Tenant, broom clean, subject to
ordinary wear and tear, condemnation and casualty damage and Alterations which
Tenant is not required to remove; shall surrender all keys to Landlord at the
place then fixed for the payment of rent; and shall inform Landlord of all
combinations of locks, safes and vaults, if any, on the Premises. Within ten
(10) days after Landlord's request following expiration or earlier termination
of this Lease, Tenant shall execute, acknowledge and deliver to Landlord an
instrument in recordable form releasing, remising and quitclaiming to Landlord
all right, title and interest of Tenant in the Premises by reason of this Lease
or otherwise.

<PAGE>

ARTICLE 9. MAINTENANCE AND REPAIRS BY LANDLORD.

            Landlord shall repair and maintain the structural and mechanical
portions of the Building, including basic plumbing, heating, ventilating, air
conditioning and electrical systems installed or furnished by Landlord, and
Landlord shall keep all Common Areas in good, clean and sanitary order;
provided, however, that if maintenance and repairs are caused in part or in
whole by the act, neglect or omission of any duty by Tenant, its agents,
servants, employees or invitees, then Tenant shall, within twenty (20) days
after demand, pay to Landlord, as additional rent, the reasonable cost of such
maintenance and repairs. If the cost paid by Tenant exceeds the applicable
deductible amount on Landlord's property insurance and Landlord is able to
collect such excess from its insurer, Landlord shall reimburse such excess
amount, less costs of collection, to Tenant. Tenant waives the provisions of
Sections 1932, 1941 and 1942 of the Civil Code of California or any similar or
successor statutes to the fullest extent permitted by law. Tenant shall not be
entitled to terminate this Lease, whether based upon actual or constructive
eviction or otherwise, withhold or abate rent, make any repair and deduct the
cost of repair from rent payable under this Lease, or be relieved of any
obligation under this Lease, if Landlord fails to make a repair or perform
maintenance. Landlord shall not be liable for any failure to make any such
repairs or to perform any maintenance, except as provided in the final sentence
of this Article, and Landlord shall not have any liability by reason of any
injury to or interference with Tenant's business arising from the making of any
repairs, alterations or improvements in or to any portion of the Building or the
Premises or in or to fixtures and equipment therein. Tenant's sole remedy for
breach of this Article by Landlord shall be an action for damages as provided
for in and limited by Section 17.6 of this Lease.

            Landlord shall perform and construct, and Tenant shall have no
responsibility to perform or construct (but may have an obligation to pay, as
set forth elsewhere in this Lease), any repair, maintenance or improvements (a)
necessitated by the acts or omissions of Landlord or any other occupant of the
Building, or their respective agents, employees or contractors, (b) occasioned
by casualty loss, acts of God or other casualty or by the exercise of the power
of eminent domain, (c) required as a consequence of any violation of any laws or
construction defects in the Premises, the Building or the Project as of the
Commencement Date, (d) for which Landlord has a right of reimbursement from
others, (e) which could be treated as a "capital expenditure" under GAAP, (f) to
the heating, ventilating, air conditioning, electrical, water, sewer, and
plumbing systems serving the Premises, the Building and the Project, and (g) to
any portion of the Building or the Project outside of the demising walls of the
Premises.

<PAGE>

ARTICLE 10. ALTERATIONS.

            10.1 Landlord's Consent. Tenant shall make no alterations, additions
or improvements (an "Alteration") in or to the Premises, without Landlord's
prior written consent. So long as the Alteration is nonstructural, is not
visible from the exterior of the Building, does not involve any work above the
dropped ceiling of the Premises and does not affect any Building systems or
their operation, Landlord's consent shall not be unreasonably withheld. If
Tenant desires to make any Alteration, Tenant shall submit detailed plans,
specifications and an itemized budget for making the Alteration. Tenant shall
pay to Landlord all reasonable costs incurred by Landlord for any architectural,
engineering, supervisory or legal services in connection with the Alteration,
including its review of the plans, specifications and budget for purposes of
determining whether to consent. Landlord may impose any reasonable conditions
and requirements to any consent as Landlord shall in its discretion deem to be
necessary, including the hours when work may be performed and insurance and
bonding requirements. Any approved Alteration shall be made only by contractors
reasonably approved by Landlord. The review, approval, inspection or examination
by Landlord or any of its agents of any plans, specifications, contractors or
any other items shall be solely for Landlord's benefit and to protect its
interests, and neither Landlord nor its agents shall be deemed to have assumed
any responsibility for the quality of work of any contractor or the accuracy,
sufficiency, quality or suitability of such plans, specifications or other
items. Tenant shall construct such Alterations in a good and workmanlike manner
and shall comply with all applicable laws and requirements of governmental
authorities and any insurance rating bureau or similar body used by Landlord's
insurers. Before commencing any work, Tenant shall deliver to Landlord at least
ten (10) days notice of the proposed commencement of such work, so that Landlord
may post and record a notice of nonresponsibility. All Alterations, including
all wall coverings, floor coverings, built-in cabinet work, paneling and the
like, shall become the property of Landlord and remain upon the Premises at the
end of the Term, except to the extent Landlord requires Tenant to remove them
pursuant to Article 8.

            10.2 Base Building Changes. In the event Tenant performs any
Alterations in the Premises which require or give rise to governmentally
required changes to the "Base Building," as that term is defined below, then
Landlord shall, at Tenant's expense, make such changes to the Base Building. The
"Base Building" shall include the structural portions of the Building, and the
public restrooms and the systems and equipment located in the internal core of
the Building on the floor or floors on which the Premises are located. In
performing the work of any such Alterations, Tenant shall have the work
performed in such manner so as not to obstruct access to the Project or any
portion thereof, by any other tenant of the Project, and so as not to obstruct
the business of Landlord or other tenants in the Project. Tenant shall not use
(and upon notice from Landlord shall cease using) contractors, services,
workmen, labor, materials or equipment that, in Landlord's reasonable judgment,
would disturb labor harmony with the workforce or trades engaged in performing
other work, labor or services in or about the Building or the Common Areas. In
addition to Tenant's

<PAGE>

obligations under Article 11 of this Lease, 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 of Los Angeles in accordance with Section 3093 of the
Civil Code of the State of California or any successor statute, and Tenant shall
deliver to the Project management office a reproducible copy of the "as built"
drawings of the Alterations as well as all permits, approvals and other
documents issued by any governmental agency in connection with the Alterations.

            10.3 Payment for Improvements. If payment is made directly to
contractors, Tenant shall comply with Landlord's requirements for final lien
releases and waivers in connection with Tenant's payment for work to
contractors. If Tenant orders any work directly from Landlord, Tenant shall pay
to Landlord a percentage of the cost of such work sufficient to compensate
Landlord for all overhead, general conditions, fees and other costs and expenses
arising from Landlord's involvement with such work.

            10.4 Construction Insurance. In addition to the requirements of
Article 14 of this Lease, in the event that Tenant makes any Alterations, prior
to the commencement of such Alterations, Tenant shall provide Landlord with
evidence that Tenant carries "Builder's All Risk" insurance in an amount
approved by Landlord covering the construction of such Alterations, and such
other insurance as Landlord may require, it being understood and agreed that all
of such Alterations shall be insured by Tenant pursuant to Article 14 of this
Lease immediately upon completion thereof. In addition, Landlord may, in its
discretion, require Tenant to obtain a lien and completion bond or some
alternate form of security satisfactory to Landlord in an amount sufficient to
ensure the lien-free completion of such Alterations and naming Landlord as a
co-obligee.

            10.5 Nonstructural Alterations; Miscellaneous. Tenant may construct
nonstructural Alterations, in the Premises without Landlord's prior approval
(but with at least 10 days prior notice to Landlord), if the cost of such work
does not exceed $20,000. If Landlord's consent is required for an Alteration and
Landlord does not notify Tenant in writing of its approval or disapproval within
twenty (20) days following Tenant's request for approval, then Landlord shall be
deemed to have approved the proposed Alteration. Upon request, Landlord shall
advise Tenant in writing whether it reserves the right to require Tenant to
remove any Alterations from the Premises upon termination of the Lease.

<PAGE>

ARTICLE 11. LIENS.

            Tenant shall keep the Premises and the Project free from any
mechanic's liens placed upon the Premises or Project by any reason of any
repairs, Tenant Improvements or Alterations contracted for or initiated by
Tenant. If any such mechanic's lien is recorded against the Premises or Project,
Tenant shall at its expense cause it to be discharged by bond or otherwise
within ten (10) days after the recording thereof. Tenant shall, promptly upon
the request of Landlord, provide Landlord with executed and acknowledged full
and unconditional lien releases in recordable form and paid receipts from any
person entitled to record a mechanic's lien furnishing labor and/or materials in
connection with any work on the Premises, as well as any other evidence
(including title searches) required by Landlord to demonstrate that there are no
liens affecting Landlord or any property of Landlord by reason of such work. Any
amount paid by Landlord to discharge or bond around any liens shall be payable
by Tenant to Landlord upon demand. Tenant shall promptly inform Landlord of the
recording or threat of recording of any mechanic's lien upon the Premises or
Project arising from or connected with Tenant's activities.

ARTICLE 12. ENTRY BY LANDLORD.

            Landlord shall at any and all times have the right to enter the
Premises for any business purpose, including (a) inspections, (b) supplying
janitorial service and any other service to be provided by Landlord to Tenant
under this Lease, (c) showing the Premises to interested parties, (d) posting
notices of nonresponsibility, and (e) altering, improving or repairing the
Premises or any other portion of the Building, all without such entry
constituting any actual or constructive eviction of Tenant and without abatement
of rent. Except in the case of the entries described in (b) above and in
emergencies, Landlord shall endeavor to give Tenant reasonable advance notice by
telephone or otherwise of its entries into the Premises. Landlord may erect
scaffolding and other necessary structures in and about the Premises where
reasonably required by the character of the work to be performed, provided that
Landlord shall use reasonable efforts to minimize interference with Tenant's
business. Tenant waives any claim for damages, for any injury or inconvenience
to or interference with Tenant's business, any loss of occupancy or quiet
enjoyment of the Premises, and any other loss in, upon and about the Premises.
Landlord shall at all times have a key with which to unlock all doors in the
Premises, excluding Tenant's vaults and safes. Landlord may use any and all
means which Landlord may deem proper to enter the Premises in an emergency. Any
entry to the Premises obtained by Landlord by any of such means shall not be
construed or deemed to be a forcible or unlawful entry into the Premises, or an
eviction of Tenant from the Premises or any portion thereof, and any damages
caused on account thereof shall be paid by Tenant.

<PAGE>

ARTICLE 13. UTILITIES AND SERVICES.

            Landlord shall furnish to the Premises the utilities and services
described in the Standards for Utilities and Services, attached hereto as
Exhibit C. Tenant agrees to perform and be bound by all of the provisions of
Exhibit C. Charges for any services, goods or materials furnished by Landlord at
Tenant's request and charges for services, goods and materials furnished by
Landlord as a result of uses or demands by Tenant in excess of those normally
furnished to other tenants in the Building with general office usage may be
billed to Tenant on its monthly rental statement and if so billed, shall payable
by Tenant together with its rent (or if not billed on the monthly rental
statement, the charges shall be payable within twenty (20) days after Landlord
delivers a statement for such services, goods or materials to Tenant).
Interruption of utilities or services (including telephone and
telecommunications services) or Landlord's failure to furnish any of such
utilities or services when such interruption or failure is caused by (i)
accident, breakage or repairs, (ii) strikes, lockouts or other labor disturbance
or labor dispute of any character, (iii) governmental regulation, moratorium or
other governmental action, (iv) inability despite the exercise of reasonable
diligence to obtain electricity, gas, water or fuel, (v) limitation, rationing,
curtailment or restriction on the use of water, electricity, gas, heating,
cooling or other forms of service or utility provided to the Premises or the
Building or (vi) any other cause beyond Landlord's reasonable control, shall not
give rise to a claim for damages against Landlord or otherwise result in any
liability to Landlord. In addition, Tenant shall not be entitled to any offset,
abatement or reduction of rent by reason of such failure, no actual or
constructive eviction of Tenant shall result from such failure and Tenant shall
not be relieved from the performance of any covenant or agreement in this Lease
because of such failure. In the event of any failure, stoppage or interruption
thereof, Landlord shall diligently attempt to resume service promptly. Tenant's
sole remedy for breach of this Article by Landlord shall be an action for
damages, as provided for and limited by Section 17.6 of this Lease.

            If Tenant is prevented from using, and does not use, the Premises or
any portion thereof, or if Tenant's ability to conduct its business operations
from the Premises is materially impaired, as a result of any failure to provide
services to the Premises, and such failure did not result from a casualty
covered by Article 15 below and was not caused directly or indirectly by an act
or omission of Tenant, its employees, agents or visitors, guests, invitees or
licensees (a "Services Failure Event"), then Tenant shall give written notice of
such Services Failure Event to Landlord. If the Services Failure Event continues
for seven (7) consecutive business days (the "Services Failure Period") after
Landlord's receipt of Tenant's written notice, then Rent shall be abated or
reduced after expiration of the Services Failure Period for 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 area of the portion of
the Premises that Tenant is prevented from using, and does not use, bears to the
total rentable area of the Premises, provided that Rent shall be abated
completely if the portion of the Premises that Tenant is prevented from using,
and does not use, is so

<PAGE>

significant as to make it impractical for Tenant to conduct its business in the
Premises and Tenant does not, in fact, for that reason, conduct its business in
the Premises.

ARTICLE 14. INDEMNITY AND INSURANCE.

            14.1 Tenant's Indemnity and Landlord's Indemnity.

                  14.1.1 Tenant shall protect, defend, indemnify and hold
Landlord, its partners, shareholders, officers, directors, trustees, employees,
agents, affiliates, representatives and management and other contractors
(collectively, "Landlord's Affiliates") harmless from and against any and all
claims, demands, judgments, loss, cost, expense, liability, damages, whether
general, special, consequential or incidental, or injury to property or persons,
resulting from or occurring by reason of: (a) the use, occupancy or nonoccupancy
of the Premises or the actions or inactions, whether negligent, of Tenant and/or
any subtenant, and their agents, officers, employees, contractors, customers,
invitees or licensees, (b) any mechanic's liens placed on the Premises or
Project arising out of any repairs, Tenant Improvements or Alterations
contracted for or initiated by Tenant, (c) any default or breach of this Lease
by Tenant (beyond any applicable notice and cure period), (d) to the extent
caused or allowed by Tenant, or any agent, employee, contractor, invitee or
licensee of Tenant, the presence on, under or the release from, onto or into the
Premises, the Project, any land, the atmosphere, or any watercourse, body of
water or ground water of any Hazardous Material, and/or (e) the failure of
Tenant or any other occupant to surrender possession of the Premises upon the
expiration of the Term, either due to Tenant's failure to timely perform its
obligations for removal and repair of personal property or any other reason,
which indemnity shall include any claims made by any succeeding tenant founded
upon such delay; provided, however, that Tenant shall not be obligated to so
indemnify Landlord or any of Landlord's Affiliates to the extent any such
matters arise from or are caused by the willful misconduct or gross negligence
of Landlord or any of Landlord's Affiliates each acting within the scope of
their authority on behalf of Landlord. If Tenant is required to defend Landlord,
Landlord shall be entitled to select its own defense counsel, and Tenant shall
pay on behalf of, or to, Landlord all reasonable defense expenses incurred by
Landlord, including reasonable attorneys' fees and expenses, fees of experts and
accountants and court costs. The indemnification set forth in this Section shall
survive the termination of this Lease.

                  14.1.2 Landlord shall protect, defend, indemnify and hold
Tenant harmless from and against any and all claims, liabilities and expenses in
connection with the loss of life, bodily or personal injury or property damage
at the Project or Premises to the extent caused by the gross negligence or
willful misconduct of Landlord, its agents, representatives or contractors. The
indemnification set forth in this Section shall survive the termination of this
Lease.

            14.2 Tenant's Insurance. Tenant shall carry, at its own expense,
throughout the Term:

<PAGE>

                  14.2.1 Liability; Worker's Compensation. Commercial general
public liability insurance covering the Premises and appurtenant areas, and
Tenant's use thereof, including a contractual liability endorsement (covering
the performance by Tenant of its indemnity agreements), in an amount not less
than $2,000,000.00 per occurrence in combined single limit and general aggregate
coverage for bodily injury, or death, personal injury and property damage.
Tenant shall keep in full force and effect, at its own expense throughout the
Term, Worker's Compensation insurance as required by law and with employer's
liability coverage of not less than $500,000.00 per employee and per occurrence.
The amounts of general liability and employer's liability insurance shall be
increased on the third anniversary of the Commencement Date and every third
anniversary thereafter to an amount reasonably determined by Landlord as may be
required, given the then current economic conditions and the size of damage
awards generally, to approximate the same level of protection as was provided on
the Commencement Date;

                  14.2.2 Property. Fire and extended coverage and sprinkler
damage insurance covering the full replacement cost (without deduction for
depreciation) of all personal property of whatever kind, including inventory
and/or goods stored at or about the Premises, Tenant's trade fixtures and
Tenant's interest in tenant improvements which may be at any time located in, on
or about the Premises or the Project, whether owned by Tenant or third parties.
All of such personal property shall be at Tenant's sole risk or at the risk of
those claiming through Tenant;

                  14.2.3 Business Interruption. Business interruption insurance
with coverages and in amounts which are customary for a business of the type and
size operated by Tenant in or from the Premises; and

                  14.2.4 Other. Such other insurance as Landlord shall
reasonably require generally of all tenants.

            14.3 Form of Insurance Policies.

                  14.3.1 General Requirements. All insurance policies required
of Tenant by this Lease shall be obtained from insurers doing business in
California having a rating of A-XIII or better in the current issue of "Best's
Insurance Guide." All loss payable clauses on property insurance shall name
Landlord (and any mortgagee of Landlord) as an additional insured. Tenant's
insurance may provide for deductibles in reasonable amounts. If Tenant requests
approval of a deductible, Tenant shall provide evidence of financial
responsibility reasonably satisfactory to Landlord to pay the deductible amount
in the event of a loss. Any policy of insurance required to be maintained by
Tenant under this Lease may be maintained under a policy commonly referred to as
a "blanket policy" insuring other parties and/or other locations; provided,
however, that the amount of insurance and the scope and type of coverage shall
conform to the requirements contained in this Lease.

<PAGE>

                  14.3.2 Delivery of Policies. Tenant shall provide Landlord
with copies of insurance policies or other evidence of such insurance coverage
prior to the Commencement Date and shall provide to Landlord copies of
replacement policies at least thirty (30) days prior to the date of expiration
of a policy. A binder or certificate of insurance shall be sufficient evidence
of insurance pending issuance of a policy; provided, however, that Tenant shall
forward a copy of each policy to Landlord when issued. Such insurance policies
shall (a) be on an occurrence basis and otherwise on forms reasonably acceptable
to Landlord, (b) name Landlord, Landlord's Affiliates (including any management
agent from time to time designated by Landlord) and any lenders of Landlord as
additional insureds, (c) provide that coverage of additional insureds shall be
primary and that any insurance maintained by Landlord shall be excess only, (d)
provide that the interests of Landlord, Tenant and other insureds shall be
severable such that the act or omission of one insured shall not avoid or reduce
the coverage of other insureds, and (e) contain endorsements (i) stating that
the insurer agrees to notify Landlord not less than thirty (30) days in advance
of modification or cancellation thereof, (ii) deleting any employee exclusion on
personal injury coverage, (iii) including employees as additional insureds, (iv)
deleting any exclusion from liability caused by serving alcoholic beverages
incidental to Tenant's business and (v) providing for coverage for employer's
nonowned automobile liability.

            14.4 Exemption of Landlord From Liability. Except to the extent such
matters both (a) arise from or are caused by Landlord's gross negligence or
willful misconduct and (b) are not covered by insurance of the injured party,
including the insurance required to be maintained by Tenant under this Lease (or
if Tenant fails to maintain such coverage, which would have been covered if such
insurance had been maintained as required), Landlord and Landlord's Affiliates
shall not be liable under any circumstances for damage, injury to Tenant's
business or loss of income therefrom or for damage, injury or loss of the goods,
wares, merchandise, vehicles or other property of Tenant, Tenant's employees,
invitees, customers or any other person in or about the Premises or any other
part of the Project or death or injury to the person of Tenant, Tenant's
employees, agents or contractors or to Tenant's property, whether such damage or
injury is caused by or results from acts or omissions of Landlord or any of
Landlord's Affiliates, whether negligent, criminal acts, fire, steam,
electricity, gas, water or rain, or from the breakage, leakage, obstruction or
other defects of pipes, sprinklers, wires, appliances, plumbing, heating,
ventilation, air conditioning or lighting fixtures, or from any other cause,
whether damage or injury results from conditions arising upon the Premises or
upon other portions of the Building or the Project, or from other sources or
places appurtenant to the Premises and regardless of whether the cause of such
damage or injury or the means of repairing the same is inaccessible to Tenant,
including any act or neglect of any other tenant of the Project, or from any
other cause whatsoever.

      14.5 Waiver of Subrogation. Landlord and Tenant each waives any and all
rights of recovery against the other (and against the officers, employees and
agents of the other party) for loss of or damage to such waiving party or its
property or the property of others under its control, to the extent such loss or
damage results from

<PAGE>

a risk which is (a) actually insured against, (b) required to insured against
under this Lease or (c) typically covered by "all-risk" property insurance . In
obtaining policies of property insurance on their respective interests in the
personal property and improvements located in the Premises and the Project,
Landlord and Tenant shall give notice to their respective insurance carriers
that the foregoing mutual waiver of subrogation is contained in this Lease; and
Landlord and Tenant shall each obtain from their insurance carriers a consent to
such waiver. If Tenant is unable to obtain a waiver of subrogation in its
insurance policies because it is determined to be unavailable or unreasonably
expensive, which determination shall be made by Landlord in its sole discretion,
the waiver by Landlord contained in this Section 14.5 shall not be effective.

            14.6 Landlord's Insurance. Landlord shall carry commercially
reasonable insurance on the Project, including "all-risk" property insurance
insuring against the risk of loss or damage to the Building and Project for the
full replacement cost thereof. If Landlord carries earthquake insurance that was
not carried during the Base Year, the costs of such earthquake insurance shall
be included in costs for the Base Year.

<PAGE>

ARTICLE 15. DAMAGE OR DESTRUCTION.

            15.1 Rights of Termination. If either the Project or the Premises
are partially or wholly destroyed or damaged by fire or other casualty, and such
damage or destruction cannot, in the reasonable judgment of Landlord's
architect, be repaired or substantially restored within 210 days of the date
Landlord receives notice of such damage or destruction (without the payment of
overtime or other premiums), Landlord shall so notify Tenant, and Landlord may,
at its option, terminate this Lease by delivering notice thereof to Tenant;
provided, however, subject to the balance of this Article 15, Landlord may not
terminate this Lease if the damage to the Building would cost less than five
percent (5%) of the replacement cost of the Building to repair (and, as set
forth below, insurance proceeds are available for such repairs). If, in the
reasonable judgment of Landlord's architect, the Premises or Project, as the
case may be, cannot be restored to a condition that will permit Tenant access to
the Premises and to resume operation of its business in the Premises within 210
days after the date Landlord receives notice of the damage or destruction,
Tenant may, at its option, terminate this Lease by delivering notice thereof to
Landlord. Any such termination notice by Landlord or Tenant must be delivered to
the other party within thirty (30) days after the date of Landlord's
notification to Tenant of the repair or restoration time, and shall take effect
thirty (30) days thereafter. In addition, Landlord may elect to terminate this
Lease by notifying Tenant in writing of such termination within sixty (60) days
after the date of damage, such notice to include a termination date giving
Tenant sixty (60) days to vacate the Premises, if one or more of the following
conditions is present: (i) the holder of any mortgage on the Building or Project
or ground lessor with respect to the Building or Project shall require that the
insurance proceeds or any portion thereof be used to retire the mortgage debt or
shall terminate the ground lease, as the case may be; or (ii) the damage occurs
during the last twelve (12) months of the Term. If either party so terminates
this Lease, rent shall be apportioned to and shall cease as of the date of such
casualty.

            15.2 Repair and Restoration. If neither party elects to terminate
this Lease under Section 15.1, then except as provided below in Section 15.3
respecting uninsured damage, the Project and the structural components of the
Premises shall be reconstructed and restored by Landlord, at Landlord's expense,
to substantially the same condition as they were prior to the casualty (except
for modifications required by zoning and building codes and other laws or by the
holder of a mortgage on the Building or Project or any other modification to the
Common Areas deemed desirable by Landlord), and the Tenant Improvements and
other nonstructural elements of the Premises shall be reconstructed and restored
by Tenant, at Tenant's expense, to substantially the same condition as they were
prior to the casualty (unless Landlord as an additional insured, elects, in its
sole discretion, to take all, or a portion, of Tenant's insurance proceeds, in
an amount satisfactory to Landlord in its sole discretion, in which event
Landlord shall reconstruct and restore the Tenant Improvements and other
nonstructural elements of the Premises to the extent of Tenant's insurance
proceeds actually received by Landlord); provided, however, that Landlord may at
its option

<PAGE>

elect to supervise and contract for the repair or reconstruction of the Tenant
Improvements and other nonstructural elements of the Premises, which work shall
nonetheless be paid for by Tenant. In the event of such reconstruction, 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 thereof; provided, however, that rent shall be abated in the
proportion which the approximate area of the damaged or destroyed portion of the
Premises (which are not occupied by Tenant as a result of such damage) bears to
the total area of the Premises from the date of the casualty until the earlier
of substantial completion of the reconstruction or the date Tenant occupies such
portion of the Premises, and this Lease shall continue in full force and effect
for the balance of the Term. Notwithstanding the foregoing, if the damage or
destruction were caused by Tenant, rent shall only be abated to the extent of
Landlord's recovery for lost rental from the Premises under any rental loss
insurance maintained by Landlord.

            15.3 Uninsured Casualty. Notwithstanding anything else to the
contrary contained in this Article 15, Landlord shall not be obligated to pay
for the repair or restoration of damage or destruction to the Premises, Building
or Project, however caused, more than the amount of the insurance proceeds
payable for the benefit of Landlord by reason of such damage or destruction. If
the sum of such insurance proceeds, are not sufficient to cover the cost of such
repair or restoration, Landlord may elect to so repair or restore and this Lease
shall continue in full force and effect, or Landlord may elect not to repair or
restore and this Lease shall then terminate.

            15.4 Interior Improvements. Notwithstanding anything to the contrary
contained in this Article 15 or any other provision of this Lease, Landlord
shall not be required to repair any injury or damage to or to make any repairs,
restorations or replacements of any of the Interior Improvements or bear the
expense of any such repair, restoration or replacement.

            15.5 Waiver of Statutory Provisions. The provisions of this Lease,
including this Article 15, 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 Building or the Project, and any statute or regulation of
the State of California, including, without limitations, 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, the Building or the Project.

<PAGE>

ARTICLE 16. EMINENT DOMAIN.

            If the whole or any part of the Premises, Building or Project 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 any adjacent property or street
shall be so taken or condemned, or reconfigured or vacated by such authority in
such manner as to require the use, reconstruction or remodeling of any part of
the Premises, Building or Project, 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 effective as of the date
possession is required to be surrendered to the authority. If more than
twenty-five percent (25%) of the rentable square feet of the Premises is taken,
or if access to the Premises is substantially impaired, in each case for a
period in excess of one (1) year), Tenant shall have the option to terminate
this Lease effective as of the date possession is required to be surrendered to
the authority. Tenant shall not because of such taking assert any claim against
Landlord or the authority for any compensation because of such taking and
Landlord shall be entitled to the entire award or payment in connection
therewith, except that Tenant shall have the right to file any separate claim
available to Tenant for 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, and for moving expenses, so long as such
claims do not diminish the award available to Landlord, its ground lessor with
respect to the Building or Project or its mortgagee, and such claim is payable
separately to Tenant. All rent shall be apportioned as of the date of such
termination. If any part of the Premises shall be taken, and this Lease shall
not be so terminated, the rent shall be proportionately abated. Tenant hereby
waives any and all rights it might otherwise have pursuant to Section 1265.130
of the California Code of Civil Procedure. Notwithstanding anything to the
contrary contained in this Article 16, in the event of a temporary taking of all
or any portion of the Premises for a period of one (1) year or less, then this
Lease shall not terminate but the Basic Rent and any 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 17. DEFAULTS AND REMEDIES.

            17.1 Tenant's Default. The occurrence of any one or more of the
following events shall be a default and breach of this Lease by Tenant:

                  17.1.1 Tenant fails to pay any rent payment or other sum due
under this Lease within five (5) days after written notice that the same is past
due.

                  17.1.2 Tenant fails to perform or observe any term, condition,
covenant or obligation required to be performed or observed by it under this
Lease for a period of thirty (30) days (or such shorter time provided herein)
after notice thereof

<PAGE>

from Landlord; provided, however, that if the term, condition, covenant or
obligation to be performed by Tenant is of such nature that the same cannot
reasonably be cured within thirty (30) days and if Tenant commences such
performance within said thirty (30) day period and thereafter diligently
undertakes to complete the same, then such failure shall not be a default
hereunder if it is cured within sixty (60) days following Landlord's notice.

                  17.1.3 Tenant abandons, or fails to occupy the Premises, for a
period of thirty (30) days.

                  17.1.4 A trustee, disbursing agent or receiver is appointed to
take possession of all or substantially all of Tenant's assets in, on or about
the Premises or of Tenant's interest in this Lease and Tenant does not regain
possession within sixty (60) days after such appointment; Tenant or any
Guarantor makes an assignment for the benefit of creditors; or all or
substantially all of Tenant's assets in, on or about the Premises or Tenant's
interest in this Lease are attached or levied upon under execution and Tenant
does not discharge the same within sixty (60) days thereafter.

                  17.1.5 A petition in bankruptcy, insolvency or for
reorganization or arrangement is filed by or against Tenant or any Guarantor
pursuant to any federal or state statute and, with respect to any such petition
filed against it, Tenant or such Guarantor fails to secure a stay or discharge
thereof within sixty (60) days after the filing of the same.

                  17.1.6 Immediately, in the event of any assignment, subletting
or other transfer for which the prior consent of Landlord is required under this
Lease and has not been obtained.

                  17.1.7 Immediately, in the event of discovery of any false or
misleading statement concerning financial information submitted by Tenant and/or
any Guarantor to Landlord in connection with obtaining this Lease or any other
consent or agreement by Landlord.

                  17.1.8 Immediately, if Tenant or any Guarantor admits in
writing its inability to pay its debts as they mature.

                  17.1.9 Immediately, upon the suspension of Tenant's right to
conduct its business, caused by the order, judgment, decree, decision or other
act of any court or governmental agency.

                  17.1.10 Tenant fails to execute, acknowledge and deliver to
Landlord, within the ten (10) day period specified in Article 19, any documents
required to effectuate an attornment, a subordination or to make this Lease or
any option granted herein prior to the lien of any mortgage, deed of trust or
ground lease, or any estoppel certificate, as the case may be.

<PAGE>

                  17.1.11 Tenant fails to execute and deliver to Landlord,
within the ten (10) day period specified in Section 26.24, any documents or
applications in connection with the granting of any easements, rights or
dedications and/or the recordation of parcel maps, subdivision maps or
restrictions, all as provided in Section 26.24.

            17.2 Landlord's Remedies. Upon the occurrence of any default (and
after the expiration of any applicable notice and cure period), Landlord shall
have the following rights and remedies, in addition to those allowed by law or
in equity, any one or more of which may be exercised or not exercised without
precluding the Landlord from exercising any other remedy provided in this Lease
or otherwise allowed by law or in equity:

                  17.2.1 Termination of Lease. Landlord may terminate this Lease
and Tenant's right to possession of the Premises. If Tenant has abandoned and
vacated the Premises, the mere entry of the Premises by Landlord in order to
perform acts of maintenance, cure defaults, preserve the Premises or to attempt
to relet the Premises, or the appointment of a receiver in order to protect the
Landlord's interest under this Lease, shall not be deemed a termination of
Tenant's right to possession or a termination of this Lease unless Landlord has
notified Tenant in writing that this Lease is terminated. If Landlord terminates
this Lease and Tenant's right to possession of the Premises, Landlord may
recover from Tenant:

                  (1) The worth at the time of the award of unpaid rent which
had been earned at the time of termination; plus

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

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

                  (4) Any other amounts necessary to compensate the Landlord for
all of 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, including any legal expenses, brokers commissions or
finders fees (in connection with reletting the Premises and the pro rata portion
of any leasing commission paid by Landlord in connection with this Lease which
is applicable to the portion of the Term, including option periods, which is
unexpired as of the date on which this Lease terminated), the costs of repairs,
cleanup, refurbishing, removal and storage or disposal of Tenant's personal
property, equipment, fixtures and anything

<PAGE>

else that Tenant is required under this Lease to remove but does not remove
(including those alterations which Tenant is required to remove pursuant to an
election by Landlord and Landlord actually removes whether notice to remove
shall be delivered to Tenant), and any costs for alterations, additions and
renovations incurred by Landlord in regaining possession of and reletting (or
attempting to relet) the Premises. Tenant shall also reimburse Landlord for the
pro rata portion of leasehold improvement costs paid by Landlord to install
leasehold improvements on the Premises which is applicable to that portion of
the Term including any terminated option periods which is unexpired as of the
date on which this Lease terminated, discounted to present value.

                  All computations of the "worth at the time of the award" of
amounts recoverable by Landlord under (1) and (2) hereof shall be computed by
allowing interest at the maximum lawful contract rate per annum. The "worth at
the time of the award" recoverable by Landlord under (3) and the discount rate
for purposes of determining any amounts recoverable under (4), if applicable,
shall be computed by discounting the amount recoverable by Landlord at the
discount rate of the Federal Reserve Bank, San Francisco, California, at the
time of the award plus one percent (1%).

                  Upon termination of this Lease, whether by lapse of time or
otherwise, Tenant shall immediately vacate the Premises and deliver possession
to Landlord, and Landlord shall have the right to re-enter the Premises.

                  17.2.2 Lease to Remain in Effect. Notwithstanding Landlord's
right to terminate this Lease, Landlord may, at its option, even though Tenant
has breached this Lease and abandoned the Premises, continue this Lease in full
force and effect and not terminate Tenant's right to possession, and enforce all
of Landlord's rights and remedies under this Lease. In such event, Landlord
shall have the remedy described in California Civil Code Section 1951.4
(Landlord may continue Lease in effect after Tenant's breach and abandonment and
recover rent as it becomes due, if Tenant has right to sublet or assign, subject
only to reasonable limitations). Further, in such event Landlord shall be
entitled to recover from Tenant all costs of maintenance and preservation of the
Premises, and all costs, including attorneys' fees and receivers' fees, incurred
in connection with appointment of and performance by a receiver to protect the
Premises and Landlord's interest under this Lease. No re-entry or taking
possession of the Premises by Landlord shall be construed as an election to
terminate this Lease unless a notice (signed by a duly authorized representative
of Landlord) of intention to terminate this Lease is given to Tenant.

            17.3 All Sums Collectible as Rent. All sums due and owing to
Landlord by Tenant under this Lease shall be collectible by Landlord as rent.

            17.4 No Surrender. No act or omission by Landlord or its agents
during the Term shall be an acceptance of a surrender of the Premises, and no
agreement to accept a surrender of the Premises shall be valid unless made in
writing and signed by a duly authorized representative of Landlord. Landlord
shall be entitled

<PAGE>

to a restraining order or injunction to prevent Tenant from defaulting under any
of its obligations other than the payment of rent or other sums due hereunder.

            17.5 Effect of Termination. Neither the termination of this Lease
nor the exercise of any remedy under this Lease or otherwise available at law or
in equity shall affect each party's right(s) of indemnification set forth in
this Lease or otherwise available at law or in equity for any act or omission of
the other party, and all rights to indemnification and other obligations of each
party intended to be performed after termination of this Lease shall survive
termination of this Lease.

            17.6 Default by Landlord and Remedies of Tenant.

                  17.6.1 Landlord Default. Landlord shall be in default under
this Lease only if it fails to perform any of its obligations under this Lease
for a period of thirty (30) days after receipt of notice thereof from Tenant;
provided, however, that if the obligation to be performed by Landlord is of such
nature that the same cannot reasonably be performed within such thirty (30) day
period, such default shall be deemed to have been cured if Landlord commences
such performance within the thirty (30) day period and thereafter diligently
undertakes to complete the same.

                  17.6.2 Tenant's Remedies. Tenant shall not have the right,
whether based upon a Landlord default, the doctrine of constructive eviction or
otherwise, to terminate this Lease or to withhold, offset or abate rent,
Tenant's sole recourse for Landlord's default being an action for damages
against Landlord for diminution in the rental value of the Premises for the
period of Landlord's default, which is proximately caused by Landlord's default.
Tenant shall not have the right to terminate this Lease or to withhold, offset
or abate the payment of rent based upon the unreasonable or arbitrary
withholding by Landlord of its consent or approval of any matter requiring
Landlord's consent or approval, including any proposed assignment or subletting,
Tenant's remedies in such instance being limited to a declaratory relief action,
specific performance, injunctive relief or an action for actual damages, and
Tenant waives any such right that it might otherwise have. Tenant shall not in
any case be entitled to any consequential or punitive damages based upon any
Landlord default, constructive eviction or withholding of consent or approval.

                  17.6.3 Limitations on Tenant's Recourse. Notwithstanding
anything to the contrary contained in this Lease, Tenant shall look solely to
the estate and property of Landlord in the Project and/or insurance proceeds
from the Project and/or proceeds from the sale of the Project for the
enforcement of any judgment (or other judicial decree) requiring the payment of
money by Landlord to Tenant by reason of any default by Landlord under this
Lease or otherwise, it being intended that no other assets of Landlord or any of
Landlord's Affiliates shall be subject to levy, execution, attachment or any
other legal process for the enforcement or satisfaction of any judgment (or
other judicial decree) obtained by Tenant against Landlord.

<PAGE>

                  17.6.4 Transfer by Landlord. Landlord shall have the right to
sell, transfer or assign its interest under this Lease, or any part thereof,
without Tenant's prior consent. After such sale, transfer or assignment, Tenant
shall attorn to such purchaser, transferee or assignee. In the event of a sale
or transfer by Landlord, the Landlord named herein or, in the case of a
subsequent transfer, the transferor, shall, after the date of such transfer, be
automatically released from all personal liability for the performance or
observance of all terms, conditions, covenants and obligations under this Lease,
provided that the transferee assumes all of such terms, conditions, covenants
and obligations of the landlord under the Lease. Landlord and Tenat agree that
it is intended that the terms, conditions, covenants and obligations of the
landlord under the Lease shall be binding upon Landlord, its successors and
assigns only during and in respect of their successive periods of ownership
during the Term.

            17.7 Non-Waiver of Default. The failure or delay by either party to
enforce or exercise at any time any rights, remedies or other provisions of this
Lease shall not be construed as a waiver thereof, or affect the validity of any
part of this Lease or the right thereafter to enforce such right, remedy or
other provision. No waiver of any default shall be held to be a waiver of any
other or subsequent default. The receipt by Landlord of less than the full rent
due shall not be construed to be other than a payment on account of rent then
due, no statement on Tenant's check or any letter accompanying Tenant's check
shall be deemed an accord and satisfaction, and Landlord may accept any payment
without prejudice to Landlord's right to recover the balance due or to pursue
any other available remedies.

ARTICLE 18. ASSIGNMENT AND SUBLETTING.

            18.1 Reasonable Consent. Neither all nor any part of Tenant's
interest under this Lease or the Premises shall be assigned, sublet, mortgaged,
pledged or otherwise transferred (whether voluntarily, involuntarily, by
operation of law or otherwise) without the prior consent of Landlord, which
shall not be unreasonably withheld. It shall not be unreasonable for Landlord to
withhold its consent for any of the following reasons which are not exclusive:

                  18.1.1 Financial Condition. The proposed assignee or sublessee
is not a reputable party or does not have a reasonable financial worth and/or
financial stability in view of the responsibilities involved;

                  18.1.2 Reputation. In the sole judgment of Landlord, the
proposed assignee or sublessee is of a character or engaged in a business which
is not in keeping with the standards of Landlord in the Project;

                  18.1.3 Governmental Authority. The proposed assignee or
sublessee is a governmental authority (or a subdivision or agency thereof);

                  18.1.4 Transfer of Options. The terms of the proposed
assignment or sublease will allow the assignee or sublessee to exercise a right
of

<PAGE>

renewal or extension, right of expansion, right of first offer or other similar
right held by Tenant;

                  18.1.5 Existing Occupant. The proposed assignee or sublessee
(A) occupies space in the Project at the time of the request for consent or is
negotiating with Landlord or has negotiated with Landlord during the six (6)
month period immediately preceding the time of the request for consent to lease
space in the Project and (B) Landlord has space available in the Project that is
comparable in size to the portion of the Premises that Tenant intends to
sublease or assign, as determined by Landlord;

                  18.1.6 Use. The proposed use or occupancy of the Premises or
any portion thereof by the proposed assignee or sublessee is inconsistent with
the Permitted Use. Landlord shall not be obligated to alter the Permitted Use or
any other provision of this Lease regarding use of the Premises or any other
matter in connection with any such proposed assignment or subletting;

                  18.1.7 Terms of Payment. The proposed assignment or sublease
provides for a rental or other payment based in whole or in part on the income
or profits derived by any person from the Premises; or

                  18.1.8 Prohibited Transaction. The proposed assignment or
sublease would result in or involve a transaction between Landlord and either:
(i) a "party in interest" within the meaning of Section 3(14) of Title I of the
Employee Retirement Income Security Act of 1974 ("ERISA"), as amended, or (ii) a
"disqualified person" within the meaning of Section 4975 of the Internal Revenue
Code of 1986 ("Code"), as amended, that would be a prohibited transaction under
ERISA or the Code.

            18.2 Conditions to Consent. Landlord's consent may be made or
withheld subject to such terms and conditions as Landlord considers necessary in
order to protect its interest in the Premises and the Project, including the
following: that any proposed assignee shall execute, acknowledge and deliver to
Landlord an agreement in form and substance satisfactory to Landlord whereby
such assignee shall assume and agree to perform all Tenant's obligations under
this Lease arising from and after the date of the transfer and whereby such
assignee agrees that notwithstanding such assignment, this Article shall
continue to be binding upon it with respect to future assignments, subleases
and/or other transfers. Landlord shall not be required to amend this Lease in
connection with any assignment or sublease. Tenant and any such proposed
assignee or sublessee shall promptly furnish to Landlord all documents,
agreements and understandings of any nature with regard to such transaction, and
such parties shall represent and warrant to Landlord in writing that the
materials so furnished to Landlord represent their entire agreement with regard
to such assignment or sublease. In addition, if Landlord requires personal
guaranties from financially responsible persons as a condition of consent, such
guarantors shall execute, acknowledge and deliver an absolute and unconditional
guaranty in a form presented by

<PAGE>

Landlord which shall contain waivers of all defenses to the maximum extent
permitted by law. Tenant and any Guarantors shall continue to be liable to
Landlord under this Lease, whether this Lease is assigned, sublet or otherwise
transferred, and in any event Tenant waives any suretyship defenses that it may
otherwise have to an action brought by Landlord, including without limitation,
those contained in Sections 2809, 2810, 2819, 2839, 2849, 2855, 2899 and 3433 of
the California Civil Code, as now hereafter amended and any similar laws.

            18.3 Submittal Procedure. If at any time Tenant desires to enter
into an assignment or sublease, Tenant shall submit to Landlord in writing: (i)
the name of the proposed assignee or sublessee, (ii) such information as to such
assignee's or sublessee's financial responsibility and standing as Landlord may
reasonably require, and (iii) the proposed sublease or assignment containing all
of the terms and conditions of the proposed assignment or sublease. Landlord may
accept rent from any person other than Tenant pending approval or disapproval of
such assignment or sublease. Landlord's consent to any transfer by Tenant shall
not constitute an acknowledgment that no default then exists under this Lease or
be deemed a waiver of any then existing default, except as may be otherwise
stated by Landlord at the time.

            18.4 Landlord's Alternatives. At any time within twenty (20) days
after Landlord receives Tenant's full submission (including any additional
information Landlord may request), Landlord may by notice to Tenant elect to:
(a) consent to the proposed sublease or assignment; (b) withhold its consent to
the proposed sublease or assignment; or (c) terminate this Lease in its entirety
in the case of a proposed assignment (but only if the assignment is for the
remainder of the Lease Term) or with respect to the proposed sublease premises
in the case of a proposed sublease (but only if the total subleased space --
measured in the aggregate and including all previous subleases -- is for more
than 25% of the Premises or is for a term exceeding 50% of the remainder of the
Lease Term) (in which case the rent, parking rights and any other rights or
obligations under this Lease which are based upon the square footage of the
Premises shall be proportionately adjusted, and Tenant shall pay the cost of any
alterations necessary to divide the proposed sublease premises from the
remainder of the Premises), which termination shall take effect on the date set
forth in Landlord's notice but in no event more than ninety (90) days after
Landlord has so notified Tenant.

            18.5 Consideration. If Tenant assigns this Lease or sublets any
portion of the Premises, Tenant shall pay to Landlord as additional rent as and
when received by Tenant:

                  18.5.1 Assignment. In the case of an assignment, an amount
equal to 50% of all "Proceeds" as defined in Section 18.5.2 immediately below.

                  18.5.2 Subleasing; Definition of Proceeds. In the case of a
sublease, an amount equal to 50% of all "Proceeds." "Proceeds" means the
difference between (i) all rent, escalations thereto, percentage rent,
additional rent and other amounts paid by the assignee or sublessee to Tenant
pursuant to the assignment or sublease, together with any key money, bonus
money, payment in excess of fair market

<PAGE>

value for services, assets, fixtures, inventory, accounts, goodwill, equipment,
furniture, general intangibles, capital stock or equity ownership rendered or
delivered by the assignee or sublessee to Tenant, less the reasonable amount of
Tenant's Transfer Costs, as hereafter defined, and (ii) the Annual Basic Rent
and additional rent or pro rata portion of the Annual Basic Rent and additional
rent, as the case may be, for the portion of the Premises covered by such
assignment and/or sublease, payable to Landlord under this Lease. "Tenant's
Transfer Costs" mean only that portion of Tenant's actual expenses in connection
with such assignment or sublease which are reasonable and customary in the
market in which the Building is located (i) to rehabilitate or improve the
portion of the Premises covered by such assignment and/or sublease for the
assignee or sublessee, (ii) for out-of-pocket attorneys fees and (iii) for
brokerage fees. For purposes of calculating the Proceeds on a monthly basis,
Tenant's Transfer Costs shall be deemed to be expended by Tenant in equal
monthly amounts over the term of the sublease or assignment. For all purposes
under this Section, a sub-sublease, assignment of sublease or any similar
arrangement shall be considered a sublease.

            18.6 Subleases. Regardless of Landlord's consent, the following
terms and conditions shall apply to any subletting by Tenant and shall be deemed
included in all subleases:

                  18.6.1 Assignment of Rents. Tenant assigns to Landlord all of
Tenant's interest in all rentals and income arising from any sublease made by
Tenant, and Landlord may collect such rent and income and apply same toward
Tenant's obligations under this Lease; provided, however, that until a Tenant
default occurs (beyond any applicable notice and cure period), Tenant may
(subject to Section 18.5) receive the rents under such sublease. Landlord shall
not, by reason of this or any other assignment of such sublease to Landlord or
the collection of the rents from a subtenant, be deemed liable to the subtenant
for any failure of Tenant to comply with any of Tenant's obligations to such
subtenant. Tenant irrevocably authorizes and directs any such subtenant, upon
receipt of a notice from Landlord that a Tenant default exists, to pay to
Landlord the rents due and to become due under the sublease. Such subtenant
shall have the right to rely upon any such statement and request from Landlord
and shall pay such rent to Landlord without any obligation to inquire as to
whether such default exists and notwithstanding any notice from or claim of
Tenant to the contrary. Tenant shall have no right or claim against the
subtenant or Landlord for any such rents so paid by the subtenant to Landlord.
The net amount after costs of collection received by Landlord from the assignee,
subtenant or occupant shall be applied to the rent without being deemed a waiver
by Landlord of any Tenant default or a release of Tenant.

                  18.6.2 Form of Sublease. No sublease shall be effective unless
and until Landlord's consent has been obtained. In entering into any sublease,
Tenant shall use only a form of sublease reasonably acceptable to Landlord, and
once approved by Landlord, such sublease shall not be modified without
Landlord's prior consent. By entering into a sublease, the subtenant shall be
deemed, for Landlord's benefit, to have

<PAGE>

assumed and agreed to perform Tenant's obligations under this Lease, other than
such obligations as are contrary to or inconsistent with provisions contained in
a sublease to which Landlord has consented.

                  18.6.3 Attornment. If Tenant defaults, Landlord, at its option
and without any obligation to do so, may require any subtenant to attorn to
Landlord, in which event Landlord shall undertake the obligations of Tenant, as
sublessor under such sublease from the time of the exercise of such option to
the termination of such sublease; provided, however, Landlord shall not be
liable for any prepaid rents or security deposit paid by such subtenant to
Tenant or for any other prior defaults of Tenant under such sublease. Landlord's
approval of a sublease shall not be construed as an agreement by Landlord to
recognize any subtenant upon the expiration or termination of this Lease,
whether voluntary or involuntary.

                  18.6.4 Termination of Lease. Subject to Landlord's right to
require attornment by any subtenant, any termination of this Lease, whether
voluntary or involuntary, shall cause each sublease to terminate,
notwithstanding Landlord's prior approval of the sublease. In the event of
voluntary termination of this Lease by agreement between Landlord and Tenant,
the foregoing sentence shall fully apply, and to the extent that any subtenant
has any claim or cause of action arising from or related to such voluntary
termination of this Lease, and resulting termination of the sublease, the
subtenant shall be conclusively presumed to have waived such claim or cause of
action as against Landlord (including Landlord's Affiliates), the Premises and
the Project, and to have agreed that any such claim or cause of action shall be
asserted solely against Tenant.

            18.7 Miscellaneous.

                  18.7.1 Deemed Assignment. Intentionally Omitted.

                  18.7.2 Landlord's Costs and Expenses. Tenant shall reimburse
Landlord for any reasonable costs and expenses (including legal expenses), not
to exceed $2,000, incurred by Landlord in connection with its review of any
proposed assignment or subletting and all related matters, whether Landlord
gives its consent.

                  18.7.3 Affiliate Transfers. Notwithstanding anything to the
contrary contained in this Article 18, Tenant may, without Landlord's prior
written consent, without any right of Landlord to terminate the Lease, and
without payment of any amount to Landlord (except Landlord's actual costs and
expenses (including attorneys fees) incurred to prepare and negotiate an
assignment and assumption agreement), sublet the Premises or assign the Lease to
(a) a subsidiary, affiliate, division or corporation controlling, controlled by
or under common control with Tenant, (b) a successor corporation related to
Tenant by merger, consolidation or nonbankruptcy reorganization, or (c) a
purchaser of substantially all of Tenant's assets (an "Affiliate Entity"),
provided that (i) the Affiliate Entity assumes, in full, the obligations of
Tenant under this Lease, (ii) the Affiliate Entity has a net worth

<PAGE>

(calculated in accordance with generally accepted accounting principles,
consistently applied) equal to or greater than the net worth of Tenant as of the
date of this Lease, (iii) Tenant remains fully liable under this Lease, (iv) the
use of the Premises remains a permitted use under this Lease, and (v) Tenant
provides Landlord with ten (10) days prior written notice of any such assignment
or subletting (provided, however, if prior notice is not permitted by law, then
notice shall be given as soon as possible). A sale or transfer of Tenant's
capital stock shall not be deemed an assignment, subletting or other transfer of
the Lease or the Premises. "Control" as used in this Section 18.7.3 shall mean
the ownership of at least 51% of all voting interests in any person or entity.

ARTICLE 19. SUBORDINATION AND ESTOPPEL.

            19.1 Subordination. At the election of Landlord, or the holder of
any mortgage or deed of trust affecting the Project or any ground lessor, this
Lease and all of Tenant's rights hereunder shall be subject and subordinate at
all times to any deed of trust, mortgage or ground lease which may now or
hereafter affect the Project, and to all renewals, modifications,
consolidations, replacements and extensions thereof. If any such mortgage or
deed of trust is foreclosed or any ground lease terminated, at the election of
Landlord's successor in interest, Tenant agrees, for the benefit of such
successor in interest, to attorn to such successor in interest and become its
tenant on the terms and conditions of this Lease for the remainder of the Term,
and if required, to enter into a new lease with such successor in interest in
the form of this Lease. Tenant's agreement to attorn shall survive the
termination of this Lease. At the request of Landlord, the holder of such
mortgage or deed of trust or any ground lessor, Tenant shall execute,
acknowledge and deliver promptly in recordable form any commercially reasonable
instrument or subordination agreement that Landlord or such holder may request;
provided, however, that such instrument shall include a provision requiring the
purchaser at any foreclosure sale to continue this Lease in full force and
effect in the same manner as if such purchaser were the Landlord so long as
Tenant is not otherwise in default (beyond any applicable notice and cure
period) and requiring Tenant to attorn to such purchaser. In addition, at the
request of Landlord, the holder of any mortgage or deed of trust or any ground
lessor, Tenant shall execute, acknowledge and deliver promptly in recordable
form any commercially reasonable instrument that Landlord or such holder may
request to make this Lease superior to such mortgage, deed or trust or ground
lease. After the Commencement Date, upon written request of Tenant, Landlord
shall endeavor to obtain, or shall permit Tenant to try to obtain from the
holder of an Encumbrance, a recognition agreement ("SNDA") from any holder of
any ground or underlying lease, mortgage, or deed of trust encumbering the
Project or any portion thereof (collectively, "Encumbrances", singularly, an
"Encumbrance") providing for the recognition of Tenant's rights, interests and
options under the Lease in the event of a foreclosure or termination of the
holder's Encumbrance.

            19.2 Estoppel. Within ten (10) days after request therefor by
Landlord, Tenant shall execute and deliver in recordable form an estoppel
certificate to

<PAGE>

any holder of a mortgage (or deed of trust) or proposed mortgage (or deed of
trust) or proposed purchaser or to Landlord certifying (if such is the case)
that this Lease is unmodified and in full force and effect (or if modified, that
the same is in full force and effect as modified and stating the modifications);
that, to the best of its knowledge, there are no uncured defaults by Landlord;
that there are no defenses or offsets against the enforcement thereof or stating
those claimed by Tenant; stating the date to which rent and other sums due
hereunder are paid; and containing such other statements regarding this Lease,
the Premises or Tenant as Landlord, the proposed mortgagee, beneficiary or
purchaser shall reasonably require. Such certificate shall also include such
other information and agreements by Tenant to protect the security interest of
any lender as may be required or requested by such lender. Tenant's failure to
deliver any such certificate within ten (10) days after request therefor shall
be deemed to constitute Tenant's certification that this Lease is in full force
and effect and has not been modified except as may be represented by Landlord,
that no rent or other payment has been paid more than one month in advance, and
that there are no uncured defaults by Landlord and there are no defenses or
offsets against the enforcement thereof.

ARTICLE 20. BUILDING PLANNING. Intentionally Omitted.

ARTICLE 21. SIGNS.

            Tenant shall not erect or maintain any temporary or permanent sign
on or about the Premises or the Project, except as provided herein and except
that Tenant may, in accordance with the provisions of this Lease (including,
without limitation, Article 10), place a sign used to identify Tenant's business
name on the exterior doorway or walls of the Premises. In addition, Tenant, at
its sole cost and expense, may install a sign used to identify Tenant's business
name on the exterior of the Building directly outside the entrance of the ground
floor premises. All signs, whether erected by Landlord or Tenant, shall conform
to Landlord's building standard signage criteria and to all laws, permits,
covenants, conditions, restrictions and easements pertaining to signs. Tenant
shall remove all signs which it has erected upon the termination of this Lease
and repair all damage caused by such removal. Tenant shall be entitled to have
installed on the Building lobby directory at Tenant's expense Tenant's Building
Percentage Share of the space on the Building directory for its name and the
names of Tenant's employees having offices in the Premises.

<PAGE>

ARTICLE 22. NOTICES.

            Except as otherwise required by law or as expressly set forth in
this Lease to the contrary, any and all notices, approvals, consents, demands,
requests and other communications required or permitted under this Lease
(collectively, a "Communication") shall be in writing and shall be delivered
either personally, by United States Certified Mail, postage prepaid, return
receipt requested or overnight courier (such as Federal Express), addressed to
each respective party at its address set forth in the Basic Lease Provisions, or
to such other address as such party shall advise the other in the manner
provided in this Article; provided, however, that any Communication to Tenant
after the Commencement Date may be made and shall be complete if delivered to
the Premises. If delivered personally, delivery shall be deemed conclusively to
occur at the time of service. If delivered by overnight courier, delivery shall
be deemed conclusively to occur on the day on which delivery occurs, if a
business day, or if not, then on the next business day. If delivered by
Certified Mail, delivery shall be deemed conclusively to occur on the third
business day after the postmark, postage meter date or the date stamped by the
United States Postal Service on a certified mail receipt. All Communications to
Landlord shall be deemed incomplete and not made unless delivered to each of the
addresses set forth in the Basic Lease Provisions and/or such other address or
addresses as Landlord shall advise Tenant by delivery of notice to Tenant in
accordance with this Section.

ARTICLE 23. BROKERS.

            Tenant warrants that it has had no dealings with any real estate
broker or agent in connection with this Lease, except the broker listed in the
Basic Lease Provisions whose commission shall be payable by Landlord, and that
it knows of no other real estate broker or agent who is or might be entitled to
a commission in connection with this Lease. If Tenant has dealt with any other
person or real estate broker with respect to leasing space in the Building,
Tenant shall be solely responsible for the payment of any fee due such person or
broker, and Tenant shall hold Landlord free and harmless from and against any
liability, costs and expenses in respect thereto, including attorneys' fees and
costs.

<PAGE>

ARTICLE 24. HOLDING OVER.

            Should Tenant, without Landlord's written consent, hold over after
termination of this Lease, Tenant shall become a tenant from month-to-month,
only upon each and all of the terms herein provided as may be applicable to a
month-to-month tenancy, and any such holding over shall not constitute an
extension of this Lease. During such holding over, Tenant shall pay in advance,
monthly rent at one hundred fifty percent (150%) of the rate in effect for the
last month of the term of this Lease, in addition to, and not in lieu of, all
other payments required to be made by Tenant hereunder, including, but not
limited to, Tenant's Building Expense Percentage of any Operating Expenses.
Nothing contained in this Article 24 shall be construed as consent by Landlord
to any holding over of the Premises by Tenant, and Landlord expressly reserves
the right to require Tenant to surrender possession of the Premises to Landlord
as provided in this Lease upon the expiration or earlier termination of the
Term. If Tenant fails to surrender the Premises upon the expiration or
termination of this Lease, Tenant agrees to indemnify, defend and hold Landlord
harmless from all costs, loss, expense or liability, including without
limitation, claims made by any succeeding tenant and real estate brokers claims
and attorney's fees.

ARTICLE 25. BANKRUPTCY OR INSOLVENCY.

            25.1 Tenant's Interest Not Transferable. In the event Tenant's
interest in this Lease, or any interest therein of Tenant or any estate hereby
created in Tenant, shall pass to any trustee or receiver or assignee for the
benefit of creditors or otherwise, by assignment, transfer, or operation of law,
this Lease shall terminate automatically and, by its own terms, shall
immediately be null and void, without re-entry or any notice by Landlord; and
Landlord shall be entitled to all rights and remedies hereunder and now or
hereafter available under law or in equity.

            25.2 Landlord's Option to Terminate. In the event the estate created
in Tenant hereby shall be taken in execution or by other process of law, or if
Tenant or Tenant's Guarantor or their respective executors, administrators, or
assigns, if any, shall be adjudicated insolvent or bankrupt pursuant to the
provisions of any state or federal insolvency or bankruptcy act, or if a
receiver or trustee of the property of Tenant or Tenant's Guarantor, if any,
shall be appointed by reason of the insolvency or inability of Tenant or
Tenant's Guarantor, if any, to pay its debts, or if any assignment shall be made
of the property of Tenant or Tenant's Guarantor, if any, for the benefit of
creditors; then, and in any such event, Landlord may, at its option, terminate
this Lease and all rights of Tenant hereunder by giving to Tenant notice in
writing of the election of Landlord to so terminate, in which event this Lease
shall cease and terminate with the same force and effect as though the date set
forth in said notice were the date originally set forth herein and fixed for the
expiration of the Term, and Tenant shall vacate and surrender the Premises but
shall remain liable as herein provided.

<PAGE>

            25.3 Tenant's Obligation To Avoid Creditors' Proceedings. Tenant or
Tenant's Guarantor, if any, shall not cause or give cause for the institution of
legal proceedings seeking to have Tenant or Tenant's Guarantor, if any,
adjudicated bankrupt, reorganized, or rearranged under the Bankruptcy laws of
the United States, and shall not cause or give cause for the appointment of a
trustee or receiver for the assets of Tenant or Tenant's Guarantor, if any, and
shall not make any assignment for the benefit of creditors, or become or be
adjudicated insolvent. The allowance of any petition under the bankruptcy law,
or the appointment of a trustee or receiver of Tenant or Tenant's Guarantor, if
any, or its assets, shall be conclusive evidence that Tenant caused, or gave
cause therefor, unless such allowance of the petition, or the appointment of a
trustee or receiver, is vacated within thirty (30) days after such allowance or
appointment. Any act described in this Section 25.3 shall be deemed a material
breach of Tenant's obligation hereunder, and upon such breach by Tenant,
Landlord may, at its option, and in addition to any other remedy hereunder,
terminate this Lease by giving Tenant notice in writing of the election of
Landlord to so terminate.

            25.4 Acceleration of Assumption or Rejection of the Lease.
Notwithstanding anything to the contrary contained herein, Tenant hereby agrees
to either assume or reject the Lease concurrently with the filing by or against
Tenant of a petition for relief under the Bankruptcy Code. In the event that
Tenant shall assume the Lease, Tenant and Tenant's Trustee (defined below) as
the case may be, shall, at the time of such assumption, (a) cure any default by
Tenant under the Lease, or provide adequate assurance that such default shall be
cured promptly; (b) compensate or provide adequate assurance of prompt
compensation to a party to the Lease (other than Tenant) for any actual
pecuniary loss resulting from such default; and (c) provide adequate assurance
of future performance under the Lease, as provided in Section 365(b)(3) of the
Bankruptcy Code. Tenant hereby agrees that (i) if Tenant shall fail to assume
the Lease upon such filing of a petition for relief under the Bankruptcy Code,
or (ii) if Tenant, and Tenant's Trustee, as the case may be, assumes the Lease
but fails to comply with subsections (a) through (c) of this Section 25.4, then
Landlord may, promptly thereafter, take whatever action it deems necessary and
appropriate to protect its interests, including, but not limited to, filing an
ex parte motion with the Bankruptcy Court for relief from the automatic stay and
for repossession of the Premises and termination of the Lease and for any other
relief available to it under the Bankruptcy Code or applicable law.

            25.5 Assumption and Assignment After Default. Notwithstanding
anything to the contrary contained herein, in the event that this Lease is
attempted to be assumed under the Bankruptcy Code by a trustee in bankruptcy for
Tenant or by Tenant as debtor in possession (hereinafter collectively referred
to as "Tenant's Trustee") and there exists a default by Tenant under Section
17.1 of this Lease or such state of facts which, with the giving of notice and
the passage of time specified in Section 17.1 of this Lease would constitute a
default by Tenant, such attempted assumption shall not be effective unless
Tenant's Trustee: (a) cures, or provides adequate assurance that it will
promptly cure, such default by Tenant; and (b)

<PAGE>

compensates, or provides adequate assurance that it will promptly compensate,
Landlord for any actual pecuniary loss to Landlord resulting from such default
by Tenant; and (c) provides adequate assurance of future performance of Tenant's
obligations and covenants under this Lease. For purposes of the foregoing
sentence, "adequate assurance of future performance" shall be deemed to include,
without limitation, adequate assurance of the following: (i) the source of
rental and other consideration due under this Lease; (ii) that assumption or
assignment of this Lease shall not breach substantially any provision in any
other lease, financing agreement, or master agreement relating to the Project;
and (iii) that assumption or assignment of this Lease shall not alter or affect
materially any other obligation or duty of Tenant nor be used to circumvent the
remainder of the provisions of this Lease. Landlord shall be entitled to
reimbursement from the estate of Tenant for all actual costs incurred by
Landlord in considering any proposed assignee of the Lease pursuant to this
Article 25.

            If this Lease is assigned to any person or entity pursuant to the
provisions of the Bankruptcy Code, fifty percent (50%) of all monies or other
considerations payable or otherwise to be delivered in connection with such
assignment shall be paid or delivered to Landlord, shall be and remain the
exclusive property of Landlord and shall not constitute property of Tenant or
the estate of Tenant within the meaning of the Bankruptcy Code. Any and all
monies or other considerations constituting Tenant's property under the
preceding sentence not paid or delivered to Tenant shall be held in trust for
the benefit of Landlord and be promptly paid to or turned over to Landlord.
Furthermore, Tenant's Trustee may assign this Lease only if: (1) Tenant's
Trustee assumes the Lease in accordance with the above provisions of Section
25.5; and (2) the assignee of Tenant's Trustee assumes all of the obligations
arising under this Lease and provides adequate assurance of its future
performance of Tenant's obligations and covenants under this Lease (whether or
not a default by Tenant has occurred under the Lease), including, without
limitation, the items listed in Section 25.5(i) through (iii) above. Any such
assignee shall, upon demand, execute and deliver to Landlord, an instrument
confirming such assumption.

            If Tenant's Trustee assumes this Lease and proposes to assign this
Lease pursuant to the provisions of the Bankruptcy Code to any person or entity
who shall have made a bona fide offer to accept an assignment of this Lease on
terms acceptable to Tenant, then notice of such proposed assignment setting
forth (a) the name and address of such person or entity; and (b) all of the
terms and conditions of such offer, shall be given to Landlord by Tenant no
later than twenty (20) days after receipt by Tenant, but in any event no later
than ten (10) days prior to the date that Tenant shall make application to a
court of competent jurisdiction for authority and approval to enter into such
assignment and assumption; and Landlord shall thereupon have the prior right and
option, to be exercised by notice given to Tenant at any time prior to the
effective date of such proposed assignment, to accept an assignment of this
Lease upon the same terms and conditions and for the same consideration, if any,
as the bona fide offer made by such persons.

<PAGE>

            25.6 Attorney's Fees. In the event that Landlord consults with an
attorney in a bankruptcy proceeding in which Tenant is the debtor, Landlord
shall be entitled to reimbursement from the estate of Tenant for all reasonable
fees and costs in connection with the application and/or defense of said
reimbursement.

ARTICLE 26. MISCELLANEOUS.

            26.1 Rules and Regulations. Tenant shall observe and comply with the
"Rules and Regulations," attached hereto as Exhibit D, and all reasonable and
nondiscriminatory modifications thereof and additions thereto from time to time
made by Landlord. Landlord shall not be responsible to Tenant for the violation
by any other tenant or occupant of the Project of the Rules and Regulations.

            26.2 Interpretation. This Lease shall be construed fairly as to all
parties and not in favor of or against any party regardless of which party
prepared this Lease. The word "including" shall mean "including without
limitation." The word "cost" and the word "expense," when used alone, shall mean
"cost and expense." This Lease shall be interpreted in accordance with the laws
of the State of California, and any issue or proceeding arising out of this
Lease shall be determined by a court of competent jurisdiction in the County of
________, California.

            26.3 Successors and Assigns. Subject to Article 18, this Lease shall
inure to the benefit of and be binding upon the parties and their respective
successors and assigns; provided, however, that Landlord, its successors and
assigns shall be obligated to perform Landlord's covenants under this Lease only
during and in respect of their successive periods of ownership during the Term.

            26.4 Surrender of Premises. The voluntary or other surrender of this
Lease by Tenant, or a mutual cancellation thereof, shall not work a merger, and
shall, at the option of Landlord, operate as an assignment to it of any or all
subleases or subtenancies.

            26.5 Attorneys' Fees. If Landlord brings suit for possession of the
Premises, for the recovery of any sum due under this Lease, or because of any
breach of this Lease, or for any other relief against Tenant, or in the event of
any other litigation between the parties respecting this Lease, all costs and
expenses, including reasonable attorneys' fees, incurred by the prevailing party
shall be paid by the other party. The "prevailing party" in any action involving
recovery of possession shall be Landlord if it recovers possession, shall be
Landlord if it does not recover possession but does obtain an award of damages
against Tenant and shall be Tenant if Tenant retains possession and does not
suffer an award of damages.

            26.6 Nonperformance by Tenant. Except as otherwise expressly
provided in this Lease, if Tenant fails to pay any sum owed to any party other
than Landlord for which it is liable hereunder or to perform any other act
required hereunder, and such failure continues for ten (10) days after notice
thereof by

<PAGE>

Landlord, Landlord may, without the obligation to do so and/or waiving or
releasing Tenant from its obligations or curing Tenant's default, make any such
payment or perform any such other act. All sums so paid and cost incurred by
Landlord together with interest at the maximum contract rate permissible by law,
from the date of such payment by Landlord, shall be payable by Tenant to
Landlord on demand as rent.

            26.7 Mortgagee Protection. If Tenant notifies Landlord of any
Landlord default, Tenant shall also notify, by registered or certified mail, any
beneficiary of a deed of trust or mortgage covering the Premises whose address
shall have been furnished to Tenant, and shall offer such beneficiary or
mortgagee a reasonable opportunity to cure the default, including time to obtain
possession of the Premises by foreclosure, if necessary to effect a cure.

            26.8 Waiver. The waiver by Landlord of any breach of any term or
condition of this Lease shall not be deemed to be a waiver of any subsequent
breach of the same or any other term or condition of this Lease, nor shall any
custom or practice which may grow up between the parties in the administration
of this Lease be deemed a waiver of or in any way affect Landlord's right to
insist upon the performance by Tenant in strict accordance with this Lease. The
subsequent acceptance of rent by Landlord shall not be deemed to be a waiver of
any preceding breach by Tenant, other than the failure of Tenant to pay the
particular rent so accepted, regardless of Landlord's knowledge of such
preceding breach at the time of acceptance of such rent.

            26.9 Identification of Tenant. If more than one person or entity
executes this Lease as Tenant, each of them is jointly and severally liable for
payment and performance of Tenant's obligations under this Lease, and the term
"Tenant" shall include each of them. The act of or notice from, or notice or
refund to, or the signature of any one or more of them, respecting this Lease,
including any renewal, extension, termination or modification, shall be binding
upon all persons executing this Lease as Tenant and any guarantor with the same
force and effect as if each had so acted or so given or received such notice or
refund or so signed or consented.

            26.10 Parking. Tenant shall have the right to lease on a monthly
basis permits for parking on an unreserved basis in the Project's parking
facilities the number of automobiles set forth in the Basic Lease Provisions.
All such permits shall be available at the same rates as established from time
to time by Landlord or Landlord's parking operator for other spaces in the same
location within the designated parking facilities. All of such parking permits
shall be provided to Tenant solely for use by Tenant's own personnel and such
permits may not be transferred, assigned, subleased or otherwise alienated by
Tenant without Landlord's prior approval except in connection with a transfer of
the Premises and/or the Lease to an Affiliate Entity. Neither Tenant's monthly
parking payments nor any other revenues derived from the parking facilities
shall be deducted from or offset against the costs and expenses of the parking
facilities for purposes of determining Operating Expenses. The use by Tenant,
its employees and invitees of the Project's parking facilities shall be subject
to such rules and regulations as from time to time are established by Landlord
or Landlord's

<PAGE>

parking operator. Landlord may adjust the number of parking permits if required
by any governmental authority. Tenant shall in addition comply with any
car-pooling or other traffic reduction policies adopted by Landlord at the
behest or requirement of any governmental authority, which may include
preferential parking for car-pool participants. Landlord may assign any
unreserved parking spaces and/or make all or a portion of such spaces reserved,
if determined by Landlord in its absolute discretion to be necessary for orderly
and efficient parking and/or to comply with any governmental requirements.

            26.11 Headings, Number and Gender. The headings in this Lease are
solely for convenience of reference and shall not in any manner amplify, limit
or modify or otherwise be used to interpret any provisions of this Lease. The
masculine, feminine or neuter gender and the singular or plural number shall
include the other.

            26.12 Lease Examination. Submission of this Lease for examination or
signature by Tenant does not constitute an offer to lease, and it shall not be
binding until execution and delivery by both Landlord and Tenant.

            26.13 Time Is of the Essence. Time is of the essence of this Lease
in all circumstances where time is an element.

            26.14 Entire Agreement; Amendment. This Lease, together with its
exhibits and attachments (which are incorporated herein and shall constitute a
part of this Lease), constitutes the entire agreement between the parties
respecting the subject matter hereof and supersedes all prior agreements,
promises, representations, negotiations and understandings of the parties
hereto, oral or written, express or implied, except for representations of
financial condition of Tenant and/or any Guarantor delivered to Landlord upon
which Landlord has relied in connection with entering into this Lease or consent
to any matter. This Lease may not be amended, except in writing executed by
Landlord and Tenant.

            26.15 Severability. If any provision of this Lease, as applied to
any party or circumstance, shall be adjudged by a court of competent
jurisdiction to be void or unenforceable for any reason, it shall not affect (to
the maximum extent permissible by law) any other provision of this Lease, the
application of such provision under circumstances different from those adjudged
by the court, or the validity or enforceability of this Lease as a whole.

            26.16 Recording. Neither Landlord nor Tenant shall record this Lease
or any memorandum or short form of this Lease.

            26.17 Modifications for Lender. If any proposed or existing lender
of Landlord shall request reasonable modifications of this Lease in connection
with its financing, Tenant shall not unreasonably withhold, delay or defer its
consent thereto, provided the modifications do not increase Tenant's obligations
or materially, adversely affect Tenant's leasehold interest or rights under this
Lease.

<PAGE>

            26.18 Payments to Affiliates. Landlord may include for all purposes
under this Lease, including the determination of Operating Expenses, payments
for services rendered or materials delivered with respect to the Project or to
the Premises (including management services, repairs and construction) by
affiliates of Landlord or its beneficiaries, provided that the fees or costs of
such services and materials are at market rates in the area in which the Project
is located.

            26.19 Landlord's Inability to Perform. Landlord shall not be in
default if Landlord cannot fulfill any of its obligations because it is
prevented or delayed from so doing by any accident, breakage, repair,
alteration, improvement, strike or labor troubles, moratorium, war, civil
unrest, act of God or any other cause beyond Landlord's reasonable control,
including energy or water shortages or governmental preemption in connection
with a national emergency, or by reason of law or any rule, order or regulation
of any governmental authority, or by reason of the conditions of supply and
demand affected by war, hostilities or other emergency. Landlord's performance
of its covenants in this Lease shall be independent of Tenant's covenants to pay
rent and perform Tenant's obligations under this Lease. Landlord's failure
perform its covenants shall not relieve Tenant of its covenants to pay rent and
perform under this Lease or entitle Tenant to any offset or abatement of rent,
and Tenant waives the benefit of any statute or rule of law now or hereafter in
effect to the contrary.

            26.20 Interest. Any past due sum payable by Tenant to Landlord shall
bear interest from the date due until paid at the annual rate of two (2)
percentage points per annum above the interest rate then most recently announced
by Citibank, N.A., New York, New York, or its successor (or if there is no such
successor, by another significant money-center bank designated by Landlord), as
its prime interest rate, as such rate may change from time to time but in no
event more than the maximum contract rate permitted by law for such type of
indebtedness.

            26.21 Common Areas. The term "Common Areas" means the Project areas
designed for use in common by all tenants of the Building and the Project and
includes, by way of illustration and not limitation, entrances and exits,
hallways, stairwells, elevators, restrooms, sidewalks, driveways, parking areas
(subject to the right of Landlord or its parking operator to control access
and/or charge for its use), landscaped areas and other areas as may be
designated as part of the Common Areas. The Premises shall include the
nonexclusive right to use the Common Areas in common with and subject to the
rights of other tenants in the Project and the rules and regulations established
by Landlord.

            26.22 Authorized Signatory. If Tenant signs as a corporation, Tenant
warrants that Tenant is a validly existing corporation qualified to do business
in California with authority to enter into this Lease, that each person
executing this Lease on behalf of the corporation is authorized to do so and
that such execution is binding on the corporation. If Tenant signs as a
partnership, limited liability company or joint venture (an "Entity"), each
person executing on behalf of Tenant warrants that Tenant

<PAGE>

is a duly authorized and existing Entity, with the authority to enter into this
Lease, that each person executing this Lease on behalf of the Entity is
authorized to do so and that such execution is binding on the Entity.

            26.23 Covenants and Conditions. Each provision of this Lease
required to be performed by Tenant is both a covenant and a condition.

            26.24 Reservations of Landlord. Landlord may change the name, number
or designation of the Building or the Project without notice or liability to
Tenant and without affecting this Lease. Without Landlord's prior consent,
Tenant shall not use the name of the Building or Project for any purpose other
than as Tenant's address. Landlord may (i) permit any tenant the exclusive right
to conduct any business if such exclusive does not conflict with any rights
expressly given herein and (ii) place such signs, notices and displays as
Landlord elects in its sole and absolute discretion in, on or about the Project,
including the Common Areas. Landlord reserves the right, from time to time, to
grant such easements, rights and dedications as it deems necessary or desirable
and to cause the recordation of parcel maps, subdivision maps and restrictions,
so long as such easements, rights, dedications, maps and restrictions do not
unreasonably interfere with Tenant's use of the Premises. Tenant shall sign any
of the aforementioned commercially reasonable documents and/or applications
therefor within ten (10) business days after Landlord's request. Landlord
reserves the right at any time to (a) change the arrangement and/or location of
entrances or passageways, doors and doorways, corridors, elevators, stairs,
toilets or other parts of the Common Area in the Building or the Project, (b)
make alterations or additions to the Building or Project and build adjoining the
same, and (c) construct, alter and add to other buildings or improvements in the
vicinity of the Building. Landlord further reserves the exclusive right to the
roof of the Building. No easement for light, air or view is included in this
Lease. Accordingly, any diminution or shutting off of light, air or view by any
structure shall not affect this Lease or impose any liability upon Landlord.

            26.25 Quiet Enjoyment. Subject to payment of all rents and other
sums required under this Lease and observance and performance of all its
obligations in this Lease and subject to the rights of any mortgagee or ground
lessor having priority over this Lease, Tenant shall peaceably hold the Premises
for the Term without hindrance or interruption by Landlord or any other person
or persons lawfully or equitably claiming by, through or under the Landlord,
subject to the terms and conditions of this Lease.

            26.26 Cumulative Rights. All rights, elections and remedies of
Landlord in this Lease shall be cumulative, no one of them shall be exclusive of
the other and Landlord may pursue any one or all of such remedies or any other
remedy or relief which may be provided by law or equity.

            26.27 Financial Statements. Tenant represents and warrants that all
financial statements and information provided to Landlord prior to execution of
this Lease or in connection with obtaining any consent are true and correct and
accurately reflect the financial condition of the person covered by such
statements as of the date of

<PAGE>

such statements and that no material adverse change has occurred since such
date. Tenant shall provide additional financial statements certified to be true
and correct and accurately presenting Tenant's financial condition from time to
time within fifteen (15) days after request by Landlord. Such statements shall
be prepared in accordance with generally accepted accounting principles and, if
such is the normal practice of Tenant, shall be audited by an independent
certified public accountant. Landlord shall keep the information set forth in
Tenant's financial statements strictly confidential.

            26.28 Waiver of Right to Trial by Jury. Tenant waives the right to
trial by jury.

            26.29 Confidentiality. Tenant shall keep the content of this Lease
strictly confidential and shall not disclose the content of this Lease to any
person other than Tenant's accountants, attorneys, space planner, lenders,
prospective subtenants and assignees and other persons doing business with
Tenant, where such information is relevant to such business activities.

            26.30 Approvals. Whenever this Lease requires an approval, consent,
designation, determination, selection or judgment by either Landlord or Tenant,
unless a different standard is expressly set forth, such approval, consent,
designation, determination, selection or judgment and any conditions imposed
thereby shall be reasonable and shall not be unreasonably withheld or delayed
and, in exercising any right or remedy hereunder, unless a different standard is
expressly permitted, each party shall at all times act reasonably and in good
faith.

ARTICLE 27. CONDITION PRECEDENT AND SUITE 225.

            The effectiveness of this Lease shall be conditioned upon the early
surrender and vacation of Suite 116 by the tenant currently occupying such
space. This condition precedent shall be solely for the benefit of Landlord and
may be waived by Landlord in its sole and absolute discretion.

            Landlord and Tenant acknowledge and agree that the parties would
like to include Suite 225 as part of the Premises as soon as reasonably
practicable after the surrender and vacation of that suite by the tenant
currently occupying the space. If, however, the current tenant of Suite 225
delays in vacating the space, and/or the Commencement Date with respect to Suite
225 does not occur before January 1, 2001, then this Lease shall remain in full
force and effect with respect to Suites 114, 116 and 118.

            The term "Premises" as used in this Lease shall mean Suites 114, 116
and 118 until the Commencement Date with respect to Suite 225, at which point
(if such date occurs), the term "Premises" shall include Suite 225.

<PAGE>

ARTICLE 28. RADIO ANTENNA. [OPEN: EXTENT OF PRE-APPROVAL OF RADIO ANTENNA]

            28.1 Grant of License. Landlord hereby grants to Tenant a license
for the term of this Lease to install, use, operate and maintain, all at
Tenant's sole cost and expense, on the roof of the Building a radio antenna
("Radio Antenna") of certain dimensions, size and appearance and in a certain
location, all as designated in Exhibit F (the "Radio Antenna Criteria").

            28.2 Installation and Use. Tenant shall pay for all costs associated
with the installation, use and maintenance of the Radio Antenna. Before
commencing installation of the Radio Antenna, Tenant shall submit to Landlord
for Landlord's approval, which shall not be withheld or delayed unreasonably, a
form describing the dimensions and appearance of the Radio Antenna, its proposed
mounting method, point of entry to the Building and cable route (the
"Installation Approval Form"). Landlord shall approve or disapprove any aspect
of the Radio Antenna within ten (10) business days of receiving the Installation
Approval Form; provided, however, Landlord shall not disapprove any aspect of
the Radio Antenna which complies with the Radio Antenna Criteria. Once approved
by Landlord (as evidenced by Landlord's signature on the Installation Approval
Form), all work by Tenant (subject to Landlord's approval of the contractor
completing the installation) shall be in strict accordance with the Installation
Approval Form. Any material modifications to the work set forth on the
Installation Approval Form must be approved by Landlord in writing. The Radio
Antenna and all supporting frames and structures shall be painted in a color of
Landlord's choice and shall bear no advertising material or wording of any sort
(other than the manufacturer's name and/or logo). The Radio Antenna and
supporting framework or structure and cabling for such Radio Antenna and
ancillary equipment shall be installed in a good and workmanlike manner. Tenant
shall use commercially reasonable efforts to take all necessary precautions to
ensure that its equipment and the installation and maintenance of the same will
(i) in no way damage the Building or existing structures thereon; (ii) not
interfere with the maintenance of the Building HVAC system, lighting system, the
parking area, or any other system of the Building; (iii) not interfere with the
operation of any existing satellite, radio, microwave or other communications
equipment of Landlord or any other tenant of the Building, or in the event there
is such an interference, Tenant will take all appropriate necessary steps in
order to promptly correct and thereby minimize (to the reasonable satisfaction
of Landlord) such interference; and (iv) comply with all applicable rules and
regulations of all governmental agencies having jurisdiction over such
equipment, and the operation and maintenance of the same. The Radio Antenna will
be used exclusively by Tenant in connection with Tenant's use as described in
this Lease and shall be removed by Tenant (at its sole cost and expense) upon
the termination of the Lease.

<PAGE>

            28.3 Insurance. Before commencing installation and during the entire
period that the Radio Antenna is situated in or about the Premises or Building,
Tenant agrees to maintain comprehensive general public liability insurance and
worker's compensation insurance, naming Landlord and Landlord's managing agent
as additional insured and providing at least $2,000,000.00 in coverage, against
claims for bodily injury, death and property damage occurring in the area
surrounding or in any way related to the Radio Antenna. Tenant shall provide
evidence of such insurance to Landlord with the Installation Approval Form and
thereafter when reasonably requested by Landlord. Such insurance may be provided
in a blanket policy or as an endorsement to Tenant's required insurance policy
under Section 14.2.

            28.4 Approvals. Tenant shall obtain any and all licenses and
approvals required by federal, state or municipal authorities with respect to
the installation or operation of the Radio Antenna and shall provide evidence
thereof to Landlord. Landlord shall cooperate with Tenant in obtaining such
licenses and approvals; Tenant, however, shall reimburse Landlord for any and
all reasonable costs incurred in connection therewith.

            28.5 Indemnification. To the fullest extent permitted by law, Tenant
shall indemnify, protect, defend and hold harmless Landlord, its agents and
employees, from and against any and all actions, causes of action, claims,
liabilities, losses, damages, fines, penalties and expenses (including but not
limited to actual attorneys' fees, court costs and litigation expenses,
including expert costs and costs of investigation), whether threatened or
actual, direct or indirect, caused by, arising out of, resulting from or related
to the installation, operation, maintenance or removal of the Radio Antenna and
any supporting framework or structure or other equipment in the area of the

                     DEFINITIONS OF RENTABLE AND USABLE AREA

1. Rentable Area. The Rentable Area shall be computed as follows: (a) rentable
area on a single tenancy floor shall mean the entire area within the exterior
walls measured from the inside surface of outer glass and extending the plane
thereof into non-glass areas, excluding elevator shafts and elevator machine
rooms, public stairs, fire towers and fire tower courts and main telephone and
electric switchboards, except where the main telephone and electric switchboards
are leased by a tenant or are a special installation (all air conditioning
floors and other areas within the Building containing equipment, enclosing
pipes, ducts or shafts shall be apportioned to the leased space that they
serve); and (b) rentable area for a partial floor shall be measured and computed
in the manner described in clause (a) above, except that (i) demising walls
separating two (2) leased premises shall be equally divided between such leased
premises, (ii) corridor walls to the finished corridor side shall be included in
the rentable area of adjacent leased space and (iii) core areas (including the
finished enclosing walls thereof but excluding any part of the core leased to a
tenant) and corridors (excluding the enclosing walls thereof) shall be
apportioned among each leased premises on such floor on the basis of the
rentable area of each such leased premises (exclusive of such corridor area) in
relation to the total rentable area of all of the leased premises on such floor
(exclusive of such corridor area).

2. Usable Area: The Usable Area shall be computed [in accordance with the
Standard Method for Measuring Floor Area in Office Buildings, ANSI Z65.1-1980,
provided that the usable square footage of the Building shall include all of the
square footage of the ground floor common areas located within the Building and
the common area and occupied space of the portion of the Building dedicated to
the service of the Building.

                                    EXHIBIT B

                              WORK LETTER AGREEMENT

            This Work Letter Agreement is an Exhibit to the Lease between
Landlord and Tenant. This Work Letter Agreement shall apply first with respect
to the tenant improvements to be constructed in Suites 114, 116 and 118. If
Suite 225 is added to the Premises as provided in the Lease, this Work Letter
Agreement shall next apply with respect to the tenant improvements to be
constructed in that suite.

            1. Space Planning. On or before June 1, 2000, Tenant shall provide
sufficient information to Landlord and to the space planner designated by
Landlord (and reasonably approved by Tenant) to enable such space planner to
prepare architectural plans, drawings and specifications (the "Plans") for the
Tenant Improvements to be initially installed in the Premises by the general
contractor selected by Landlord pursuant to this Work Letter Agreement. Landlord
shall submit the Plans to Tenant for Tenant's initial approval within ten (10)
business days after receipt from the space planner. Each time that proposed
Plans are submitted to Tenant, Tenant shall have a period of seven (7) business
days after delivery of the Plans to approve or disapprove them by giving written
notice thereof to Landlord. Failure of Tenant to approve or disapprove within
such period shall be deemed to be an approval. Tenant's written notice of
disapproval, if any, shall specify in detail the nature of Tenant's objections,
and Tenant agrees, if necessary, to meet promptly with the space planner to
review Tenant's objections. If Tenant timely disapproves, then the Plans will be
revised by the space planner to address Tenant's objections and resubmitted to
Tenant for its initial approval. If Tenant continues to disapprove the Plans
after the second resubmission to Tenant, then Landlord may (i) at any time
thereafter elect to terminate the Lease without further liability to Tenant, and
unless Tenant can show that its failure to approve is due to material errors of
the space planner in reflecting Tenant's reasonable requirements, Tenant shall
be required to reimburse Landlord within ten (10) days after written demand for
all expenses incurred by Landlord in connection with the Lease, including
brokerage commissions, or (ii) continue to have the Plans revised and
resubmitted to Tenant until approved, in which case the time period commencing
on the date of expiration of the seven (7) business day period for Tenant's
approval of the second resubmission of Plans until the date of Tenant's initial
approval shall be deemed to be a Tenant Delay (as hereinafter defined). Tenant
agrees that the Plans shall be the complete and final layout, plans and
specifications for the Premises showing all doors, light fixtures, electrical
outlets, telephone outlets, plumbing improvements (if any), data systems wiring,
floor coverings, wall coverings, painting and other improvements to the Premises
beyond the shell and core improvements provided by Landlord. Tenant further
acknowledges and agrees that the improvements shown in the Plans shall (i) be
compatible with the shell and core improvements and the design, construction and
equipment of the Building and the Landlord's building standards established from
time to time, (ii) comply with all applicable laws, rules,

<PAGE>

regulations, codes and ordinances and (iii) be subject to the approval of
Landlord, which approval shall not be unreasonably withheld.

            2. Approval of Plans and Cost Estimate.

                  (a) General Contractor's Cost Estimate. As soon as practicable
after receipt of Tenant's initial approval, Landlord shall submit to Tenant (i)
a written nonbinding itemized estimate of the costs of all improvements shown in
the Plans prepared by the general contractor selected by Landlord in accordance
with this Work Letter Agreement to perform the construction and (ii) if Landlord
so elects, a written description of those matters and items shown in the Plans
which Landlord believes may result in any Tenant Delay (as defined below)
together with a description of the estimated period of such Tenant Delay;
provided, however, that Tenant will be charged with the actual Tenant Delays
that occur, notwithstanding the failure of Landlord to give description of
estimated Tenant Delays at all or as to any particular item of Tenant Delay or
any inaccuracy in the estimates of Tenant Delay given to Tenant. If Landlord
disapproves any portion of the work to be performed in accordance with the
Plans, Landlord and Tenant shall promptly take all such action as may be
reasonably required to modify any aspect of the Plans so as to be reasonably
satisfactory to Landlord and Tenant and in accordance with the standards in
Paragraph 1 of this Work Letter Agreement.

                  (b) Final Approval by Tenant. Within five (5) business days
after receipt of the written nonbinding cost estimate prepared by the general
contractor and any description of any Tenant Delay which Landlord elects to
provide to Tenant, Tenant shall (i) give its written approval thereof and
authorization to proceed with construction or (ii) deliver to Landlord and the
space planner specific written changes to the Plans in any manner desired by
Tenant to decrease the Cost of the Tenant Improvements or minimize the amount of
the Tenant Delay. The general contractor shall provide a revised cost estimate
to Tenant based upon the revisions to the Plans. Such modifications and
revisions shall be subject to Landlord's reasonable approval and shall be in
accordance with the standards set forth in Paragraph 1 of this Work Letter
Agreement. Within twenty (20) business days after receipt of the general
contractor's original written cost estimate and the description, if any, of
Tenant Delay, Tenant shall give its final approval of the Plans to Landlord
which shall constitute authorization to commence the construction of the Tenant
Improvements in accordance with the Plans, as modified or revised. Tenant shall
signify its final approval by signing a copy of each sheet or page of the Plans
and delivering such signed copy to Landlord. If the general contractor's cost
estimate for the Tenant Improvements to be constructed in accordance with the
Plans exceeds the Tenant Improvement Allowance (as defined below), then Tenant
shall deliver at the time of its approval its check in favor of Landlord in an
amount equal to such excess together with delivery of the approved copy of the
Plans. If Tenant does not approve the Plans and authorize Landlord to proceed
with the construction of the Tenant Improvements within the period of time
specified in this Paragraph, then Tenant shall be charged with all costs
incurred by reason of any delay in completion of the construction of Tenant
Improvements and such

<PAGE>

delay shall be an element of Tenant Delay. If Tenant delays final approval and
authorization to commence with construction of Tenant Improvements for a period
of thirty (30) days beyond the period of time specified in this Paragraph, then
such delays shall be an event of default by Tenant under the Lease and Landlord
may, in addition to all of the other remedies which it may have under the Lease,
terminate the Lease. Tenant acknowledges that the cost estimate is prepared by
the general contractor and Landlord shall not be liable to Tenant for any
inaccuracy in the general contractor's estimate.

            3. Completion of Construction of Tenant Improvements. As soon as
practicable following receipt of Tenant's final approval of the Plans and
authorization to proceed with construction, the Plans shall be submitted to the
appropriate governmental agency for issuance of a building permit or other
required governmental approval prerequisite to construction. Following approval
of the Plans by governmental authorities and receipt of all required permits,
Landlord shall authorize the general contractor to commence construction of the
Tenant Improvements and proceed to complete such construction in a workmanlike
manner. The general contractor shall be selected by Landlord from three general
contractors who will be invited to bid on the construction of the Tenant
Improvements. One of the three general contractors submitting a bid shall be
selected by Tenant, provided that such contractor must meet Landlord's uniform
criteria for all general contractors. Landlord shall select as the final general
contractor the firm which Landlord, in its reasonable discretion, determines has
submitted the best overall bid, taking all factors, including price, into
account.

            4. Tenant Delay. "Tenant Delay" shall include any delay in the
completion of construction of Tenant Improvements resulting from (i) Tenant's
failure to comply with the provisions of this Work Letter Agreement, (ii) any
additional time as reasonably determined by Landlord required for ordering,
receiving, fabricating and/or installing items of materials or other components
of the construction of Tenant Improvements, including mill work, which are not
used in the construction of Tenant Improvements in accordance with Landlord's
Building standards and which causes a delay in the substantial completion of the
Tenant Improvements beyond the time when such improvements would otherwise be
completed if constructed in accordance with the standards used in the remainder
of the Building, (iii) delay in work caused by submission by Tenant of a request
for any Change Order following Tenant's approval of the Plans or (iv) any
additional time, as reasonably determined by Landlord, required for
implementation of any Change Order with respect to the Tenant Improvements. If
there shall be any Tenant Delay, then Landlord may, in accordance with Sections
2.1 and 2.4 of the Lease, require Tenant to commence the payment of rent under
the Lease based upon when substantial completion would have occurred but for the
Tenant Delay, or if not previously required by Landlord, Tenant shall pay such
rent to Landlord prior to Tenant occupying the Premises.

<PAGE>

            5. Cost of Work.

                  (a) Tenant Improvement Allowance. Landlord shall pay the cost
of work to construct all Tenant Improvements to the extent such cost of work
does not exceed an amount equal to the applicable sum set forth in Item No. 13
of the Basic Lease Provisions. Such amount shall be the "Tenant Improvement
Allowance". If the actual cost of work exceeds the Tenant Improvement Allowance,
Tenant shall bear the cost of such excess and shall pay the cost of such excess
to Landlord pursuant to Subparagraph (c) below to the extent not previously paid
to Landlord. Tenant shall not be entitled to any credit, abatement or payment
from Landlord in the event that the Tenant Improvement Allowance exceeds the
cost of the work, all of such excess to remain Landlord's sole property. The
following additional costs shall also be included in the cost of the work: (i)
the cost of permits and licenses, (ii) fees for the services of engineers,
architects, space planners and other consultants, (iii) the fees paid to the
contractor, (iv) the cost of cable and other telecommunications lines installed
as part of the Tenant Improvements (but specifically excluding any costs in
connection with the installation of Tenant's telephone service), (v) sales and
use taxes and Title 24 fees, (vi) the cost of any changes to the Plans or Tenant
Improvements required by applicable governmental regulations or building codes,
(vii) the cost of any changes in the base building or the floor of the Building
on which the Premises is located (when such changes are required by the Plans or
to comply with applicable governmental regulations or building codes), and
(viii) Landlord's administrative fee in the amount of five percent (5%) of the
cost of the work.

                  (b) Costs of Tenant Delay or Change Order. Tenant shall bear
the net increase in the cost of work for the construction of Tenant Improvements
incurred by reason of any Tenant Delay or any Change Order requested by Tenant
irrespective of whether the total cost of work exceeds the amount of the Tenant
Improvement Allowance.

                  (c) Payments to Landlord. Tenant shall pay any sums due to
Landlord under this Paragraph as follows:

                        (i) The estimated amount of any excess of the cost of
work over the Tenant Improvement Allowance shall be paid to Landlord at the time
of final approval of the Plans by Tenant in accordance with Paragraph 2(b)
above, and

                        (ii) All remaining amounts due to Landlord shall be paid
upon the earlier of substantial completion of the Tenant Improvements or
presentation of a written statement of the sums due, which statement may be an
estimate of the cost of any component of the work.

                  (d) Cost Exclusions. Notwithstanding anything to the contrary
herein, Landlord shall pay, and Tenant shall have no responsibility for (and the
Tenant Improvement Allowance shall not be used for) the following costs
associated with the

<PAGE>

Tenant Improvements: (i) costs attibutable to improvements installed outside of
the demising walls of the Premises; (ii) costs for improvements which are
neither shown on or described in the Final Plans, consistent at all with the
Final Plans, or otherwise approved by Tenant; (iii) costs incurred to remove
Hazardous Materials from the Premises or Project (unless the presence of such
Hazardous Materials is caused by Tenant); (iv) attorneys' fees incurred in
connection with the negotiation of construction contracts and attorneys' fees
and experts' fees and other costs in connection with disputes with third
parties, including the General Contractor; (v) penalties and late charges
attibutable to Landlord's failure to pay construction costs (provided Tenant
makes timely progress payments as required under this Lease); (vi) costs to
bring the Premises and the Project in compliance with applicable Laws, unless
such costs are triggered by the Tenant Improvements or the use or occupancy of
the Premises by Tenant; (vii) interest and other costs of financing
construction; and (viii) wages, labor and overhead for overtime and premium
time, unless requested or approved by Tenant.

            6. Change Orders. Tenant may request a change, addition or
alteration in the Tenant Improvements as shown by the Plans after its final
approval of such Plans ("Change Order") by delivery of a written request to
Landlord. If Landlord approves Tenant's requested change, addition or
alteration, Landlord's space planner shall complete all working drawings
necessary to show the change, addition or alteration. Landlord shall promptly
give Tenant a written description of the changes requested by Tenant
incorporated in a Change Order for approval by Tenant together with an estimate
of the Tenant Delay caused by such Change Order and an estimate of the cost of
work to implement the Change Order. Following the receipt of the description of
the Change Order and the estimates, Tenant shall deliver to Landlord Tenant's
written approval of the Change Order and authorization to proceed with the work
as shown by the Change Order. Landlord may, but shall not be obligated to, order
the contractor to stop work until after approval of the Change Order by Tenant
if Landlord reasonably determines that such delay is necessary or desirable to
incorporate the Change Order. Any delay caused by such work stoppage shall
constitute Tenant Delay.

            7. Substantial Completion and Punch List Items.

                  (a) Date of Substantial Completion. Substantial completion of
construction of Tenant Improvements shall be defined as the later of (i) the
date of issuance of a certificate of occupancy or other approval of occupancy of
the Premises by the appropriate governmental authority or (ii) the date upon
which Landlord's space planner or other consultant furnishes Landlord and Tenant
with a certificate stating that the Tenant Improvements have been substantially
completed in accordance with the Plans, except for such items that constitute
minor defects or adjustments which can be completed after occupancy without
causing any material interference with Tenant's use of the Premises (so called
"Punch List" items).

<PAGE>

                  (b) Completion of Punch List Items. Within fifteen (15) days
after receipt of the certificate of substantial completion, Tenant shall supply
to Landlord a written Punch List setting forth all corrective work to the Tenant
Improvements which Tenant believes is required to be performed. Landlord shall
perform all such corrective work to the extent necessary to complete
construction of the Tenant Improvements in accordance with the Plans as
determined by Landlord's space planner or other consultant as soon as practical
after receipt of the Punch List. If Tenant does not deliver a Punch List within
such fifteen (15) day period, Tenant shall be deemed to have accepted the
Premises in their entirety, and Landlord shall have no further obligation with
respect to completion of any construction of Tenant Improvements or any other
alteration, modification or change of the Premises after certification by
Landlord's space planner or other consultant that items set forth in the Punch
List have been completed.

            8. Warranties. Following completion of the Tenant Improvements and
Tenant's occupancy of the Premises, Landlord shall assign to Tenant all
warranties and rights with respect to the repair and replacement of defective
Tenant Improvements which it holds against the contractor or other parties and
shall thereafter cooperate with Tenant in enforcing the same. Upon expiration or
early termination of this Lease, all such warranties and rights shall
automatically revert to Landlord, and Tenant shall execute and deliver to
Landlord all such documents reasonably requested by Landlord to document such
reversion.

            9. Materials. All material and equipment installed in the Premises
by Landlord shall be at least equal in quality to Landlord's building standard
materials. Landlord shall use reasonable efforts to perform all construction in
a manner reasonably consistent with the Final Plans.

                                    EXHIBIT C

                      STANDARDS FOR UTILITIES AND SERVICES

            This Exhibit C, Standards for Utilities and Services, supplements
the Lease between Landlord and Tenant to which this Exhibit is attached.

            Landlord shall provide the utilities and services set forth in this
Exhibit at all times during the Term of the Lease subject to the provisions of
the Lease concerning Landlord's inability to supply such utilities and services
due to causes beyond Landlord's control. Landlord reserves the right to adopt
such reasonable nondiscriminatory modifications and additions to the following
standards as it deems necessary and appropriate from time to time. Landlord
shall not be obligated to supply any utilities or services to Tenant at any time
during which Tenant is in default under the terms of the Lease.

            1. Landlord shall provide automatic elevator services on Monday
through Friday from 7:00 a.m. to 7:00 p.m. and on Saturday from 9:00 a.m. to
1:00 p.m.; provided, however, that Landlord shall not be obligated to provide
such elevator services on any day which is designated as a federal holiday or on
any Saturday which precedes or follows any federal holiday (such times referred
to in this Exhibit as "Business Hours"). At all other times Landlord shall
provide at least one elevator operated by security personnel or by an automatic
security access system.

            2. Landlord shall provide to the Premises, during Business Hours
(and at other times for an additional charge to be fixed by Landlord), heating,
ventilation and air conditioning ("HVAC") when and to the extent in the judgment
of Landlord any such services may be required for the comfortable occupancy of
the Premises for general office purposes. Landlord shall not be responsible for
room temperatures and conditions in the Premises if the lighting or receptacle
load for Tenant's equipment and fixtures exceed those listed in Paragraph 3 of
this Exhibit, if the Premises are used for other than general office purposes or
if the Building standard blinds and curtains in the Premises are not used and/or
closed to screen the rays of direct sunlight. If any lights, machines or
equipment (including computers) are used by Tenant in the Premises which
materially affect the temperature otherwise maintained by the Building HVAC or
generate substantially more heat in the Premises than would be generated by the
Building standard lights and usual fractional horsepower office equipment,
Landlord shall have the right to install any machinery and equipment which
Landlord reasonably deems necessary to restore temperature balance (including
modifications to the standard HVAC equipment) and the cost thereof, including
the cost of installation and any additional cost of operation and maintenance
occasioned thereby, shall be paid by Tenant to Landlord upon demand by Landlord.
Landlord shall make after-hours HVAC (e.g., during hours which are not Business
Hours) available to

<PAGE>

Tenant by card-key at the cost of $35/hour (which charge is subject to increase
from time to time).

            3. Landlord shall furnish to the Premises electric current for
routine lighting and operation of general office machines such as typewriters,
dictating equipment, desk model adding machines and similar devices which
operate on 110 volt alternating current electrical power with demands, wattages
and ampere draws which do not exceed the reasonable capacity of Building
standard office lighting and receptacles and are not in excess of limits imposed
or recommended by governmental authorities. Landlord shall replace bulbs and/or
ballasts in Building standard florescent lighting fixtures within the Premises.
Tenant shall be responsible for replacing all other bulbs and/or ballasts.
Landlord shall furnish to the lavatories within the Premises or within the
Common Areas water for normal lavatory and drinking purposes.

            4. No special electrical equipment, air conditioning systems,
heating systems or space heaters shall be installed, nor shall any changes be
made to the HVAC, electrical or plumbing systems in the Building, without the
prior written approval of Landlord in accordance with the provisions of the
Lease governing alterations requested by Tenant. Tenant shall not without the
prior written consent of Landlord use any apparatus, machines or devices in the
Premises (including any machines or equipment of the type referred to in the
preceding sentence) which use current in excess of 110 volts alternating current
or which have demand wattages or ampere draws which exceed the capacity of the
electrical systems installed in the Building or which will in any way increase
the amount of electricity or water normally consumed by comparable space used
for general office purposes.

            5. To the extent Tenant requires any supplemental HVAC units,
Landlord shall install such HVAC units, with all costs relating thereto to be
deducted from the tenant improvement allowance. If possible, all charges
relating to the operation and maintenance of such supplemental HVAC units shall
be separately metered; all such charges shall be paid by Tenant.

            6. Landlord may impose reasonable conditions upon any consent for
use of any apparatus, machine or device which exceeds the limitations set forth
in this Exhibit. Tenant agrees to cooperate fully with Landlord at all times to
abide by all reasonable regulations and requirements which Landlord may
prescribe for proper functioning and protection of the Building HVAC,
electrical, plumbing and other systems. Tenant shall comply with all laws,
statutes, ordinances and governmental rules and regulations now in force or
which may be enacted or promulgated in connection with utility services
furnished to the Premises, including any governmental rule or regulation
relating to the heating or cooling of the Building or relating to the use of
energy or water.

            7. Landlord shall provide janitorial services to the Premises on
each day Monday through Friday or Sunday through Thursday (except federal
holidays), at Landlord's election, provided the Premises are used exclusively
for the uses permitted by the Lease and are kept in reasonable order by Tenant.
Tenant shall pay to Landlord

<PAGE>

any extra cost for cleaning or removal of any rubbish or garbage to the extent
the nature or amount of such cleaning, refuse or garbage exceeds the amount
which is generally produced by use of the Premises for general office purposes.
<PAGE>

                                    EXHIBIT D

                              RULES AND REGULATIONS

      Tenant shall faithfully observe and comply with the following Rules and
Regulations. Landlord shall not be responsible to Tenant for the nonperformance
of any of the Rules and Regulations by or otherwise with respect to the acts or
omissions of any other tenants or occupants of, or visitors to, the Project.

      1. Tenant shall not alter any lock or install any new or additional locks
or bolts on any doors or windows of the Premises without obtaining Landlord's
prior written consent. Tenant shall bear the cost of any lock changes or repairs
required by Tenant. Two keys will be furnished by Landlord for the Premises, and
any additional keys required by Tenant must be obtained from Landlord at a
reasonable cost to be established by Landlord. Upon termination of the Lease,
all keys to the Building and the Premises shall be surrendered to Landlord.
Notwithstanding the foregoing, Landlord hereby consents to Tenant's installation
of an electronic alarm and card-key system in the Premises, provided that Tenant
installs the alarm and card-key system in a good, workmanlike and lien-free
manner, and Tenant provides Landlord with keys, cards, security codes or the
like in order for Landlord to access the Premises in accordance with the Lease.

      2. All doors opening to public corridors shall be kept closed at all times
except for normal ingress and egress to the Premises.

      3. Landlord reserves the right to close and keep locked all entrance and
exit doors of the Building during such hours as are customary for comparable
buildings in the vicinity of the Project. Tenant, its employees and agents must
be sure that the doors to the Building are securely closed and locked when
leaving the Premises if it is after the normal hours of business for the
Building. Any tenant, its employees, agents or any other persons entering or
leaving the Building at any time when it is so locked, or any time when it is
considered to be after normal business hours for the Building, may be required
to sign the Building Register when so doing. Access to the Building may be
refused unless the person seeking access has proper identification or has
previously arranged a pass for access to the Building. The Landlord and
Landlord's Affiliates shall in no case be liable for damages for any error with
regard to the admission to or exclusion from the Building of any person. In case
of invasion, mob riot, public excitement or other commotion, Landlord reserves
the right to prevent access to the Building during the continuance of same by
any means it deems appropriate for the safety and protection of life and
property.

      4. No furniture, freight or equipment of any kind shall be brought into
the Building without prior notice to Landlord. All moving of the same into or
out of the Building shall be scheduled with Landlord and done only at such time
and in such

<PAGE>

manner as Landlord shall designate. Notwithstanding the foregoing, Tenant may
receive deliveries in the ordinary
<PAGE>

course of Tenant's business at any time and Tenant shall be permitted to use the
freight entrance to the Premises at any and all times. Landlord shall have the
right to prescribe the weight, size and position of all safes and other heavy
property brought into the Building and also the times and manner of moving the
same in and out of the Building (subject to the preceding sentence). Safes and
other heavy objects shall, if considered necessary by Landlord, stand on
supports of such thickness as is necessary to properly distribute the weight.
Landlord will not be responsible for loss of or damage to any such safe,
property or equipment in any case. All damage done to any part of the Building,
its contents, occupants or visitors by moving or maintaining any such safe or
other property shall be the sole responsibility of Tenant and any expense of
said damage or injury shall be borne by Tenant.

      5. Tenant shall not place any object or series of objects on the floors of
the Premises in such a manner as to exceed the load capacity of the floors on a
per square inch basis as determined by any architect, engineer or other
consultant of Landlord, or as otherwise limited by law or any governmental
authority.

      6. No furniture, packages, supplies, equipment or merchandise will be
received in the Building or elsewhere within the Project, or transported in the
elevators or other Common Areas of the Building, except between such hours and
in such specific elevator or other Common Areas of the Building as shall be
designated by Landlord. Landlord may in addition impose other requirements
regarding the time, place and manner of all deliveries made to the Premises.

      7. Landlord shall have the right to control and operate the public
portions of the Project, the public facilities, the Building HVAC system and any
other facilities furnished for the common use of tenants, in such manner as
