thereafter. In the event the term of this Lease commences or ends on a day
other than the First or last day of a calendar month, or in the event

proportionate share thereof (hereinafter, respectively, "Building Expense
Percentage" and "Project Expense Percentage") shall be the percentage
obtained by dividing the average Rentable Area of the Premises for such
year or portion thereof by ninety-five percent (95%) of the total Rentable
Area of the Building or the Project, as the case may be, for the same
period, and, subject to Exhibit "A-4," shall initially be as set forth in
Items 3.A. and 3.B. of the Basic Lease Provisions.


     (b) Prior to commencement of the Lease term and of each calendar year 
thereafter, Landlord shall give Tenant a written estimate of Building 
Operating Expenses and Project Operating Expenses and Tenant's proportionate 
shares thereof for the ensuing year or portion thereof. Tenant shall pay such 
estimated amount to Landlord in equal monthly installments, in advance. 
Within ninety (90) days after the end of each calendar year, Landlord shall 
furnish to Tenant a statement showing in reasonable detail the actual 
Building and Project Operating Expenses for such period in accordance with 
subparagraph (d) below, and the parties shall make any payment or allowance 
necessary to adjust Tenant's estimated payment to Tenant's proportionate 
share as shown by such annual statement. Any amount due from Tenant shall be 
paid within ten (10) days after receipt of such statement. Any amount due to 
Tenant shall be credited against installments of Additional Rent next comning 
due under this Paragraph 3 or if the Lease has terminated, such amount shall 
be paid by Landlord to Tenant within thirty (30) days of Tenant's receipt of 
the statement.

     (c) If at any time during any calendar year of the Lease term the
amount(s) and/or the rates for any item(s) of Operating Expenses for the
Building or the Project are increased to a rate(s) or amount(s) in excess
of the rate(s) or amount(s) used in calculating the estimated Building or
Project Operating Expenses for such calendar year, Tenant's estimated share
of such Building or Project Operating Expenses shall be increased for the
month in which such increase becomes effective and for succeeding months
by Tenant's Building Expense Percentage or Project Expense Percentage of
such increase, as applicable. In the event of such an increase in rate or
amount, Landlord shall give Tenant written notice (the "Adjustment
Notice") of the amount or estimated amount of increase, the month in
which effective, and Tenant's monthly share thereof. Commencing with
the first monthly payment of estimated Building Operating Expenses or
Project Operating Expenses, as applicable, required to be made by Tenant
after receipt of the Adjustment Notice (the "First Adjustment Payment"),
Tenant shall pay such increase to Landlord as part of Tenant's monthly
payments of estimated Building Operating Expenses or Project Operating
Expenses, as applicable, as provided in subparagraph (b) above. If the
effective date of the increase is prior in time to the date of the
Adjustment Notice, the First Adjustment Payment shall be increased to
include the amount of the monthly payments, if any, which would have been
made had the Adjustment Notice been received prior to the effective date of
the increase.

as foreseen, which are levied with respect to the Project, and any 
improvements, fixtures and equipment and other property of Landlord, real or 
personal, located in the Project and used in connection with the operation of 
the Project and the land upon which situated, (ii) any tax, surcharge or 
assessment which shall be levied in addition to or in lieu of real estate or

incurred in the operation and maintenance of the Project which are not (A) 
Building Operating Expenses or (B) Operating Expenses directly and separately 
identifiable to the operation and maintenance of other buildings in the 
Project.

     (e) Notwithstanding anything to the contrary contained in subparagraph (d)
immediately above, as to each specific category of expense which one or
more tenants of the Building or the Project either pays directly to third
parties or actually reimburses to Landlord (for example, separately metered
utilities, property taxes directly reimbursed to Landlord, etc.) then each
such expense which is actually paid or reimbursed shall not be included in
"Operating Expenses" for purposes of this Paragraph 3. Tenant's Building
and Project Operating Expense Percentages, as appropriate, for each such
category of expense shall be adjusted by excluding from the denominator
thereof the Rentable Area of all such tenants paying such category of
expense directly to third parties or actually reimbursing same directly to

reimburses Landlord for any such category of expense, each such category of
expenses which is paid or actually reimbursed by Tenant shall be excluded

(after deduction of that portion paid or directly reimbursed by Tenant) was
incurred with respect to space in the Building or Project, respectively,
actually leased to other tenants.

Operating Expenses shall be made by Landlord and the fact that such Operating

Landlord. A copy of Landlord's determination and such certification shall be 
made available to Tenant upon request. Landlord's determination and such 
certification shall be final and binding upon Landlord and Tenant.

     (g) The Basic Annual Rent, as adjusted pursuant to Paragraph 2, the 
Additional Rent and all other amounts required to be paid by Tenant 
hereunder, are sometimes herein collectively referred to as, and shall

this Lease, within five (5) business days thereafter, Tenant shall pay to 
Landlord as an additional security deposit an amount equal to one twelfth 
(1/12) of the difference between the new Basic Annual Rent and the Basic 
Annual Rent in effect immediately prior to such increase. If Tenant defaults 
with respect to any provision of this Lease, including but not limited to the 
provisions relating to the payment of rent, Landlord may, but shall not be 
required to, use, apply or retain all or any part of this security deposit 
for the payment of any rent of any other sum in default, or for the payment 
of any other amount which Landlord may spend or become obligated to spend by 
reason of Tenant's default or to compensate Landlord for any other loss or 
damage which Landlord may suffer by reason of Tenant's default, including 
without limitation, costs and attorneys' fees incurred by Landlord to recover 
possession of the Premises upon a default by Tenant hereunder. If any portion 
of said deposit is so used or applied, Tenant shall, within five (5) days 
after receipt of written demand therefor, deposit cash with Landlord in an 
amount sufficient to restore the security deposit to its original amount and 
Tenant's failure to do so shall constitute a default hereunder by Tenant. If 
Tenant shall fully and faithfully perform every provision of this Lease to be 
performed by it, the security deposit shall be applied against any amounts 
owed by Tenant to Landlord at the expiration or termination of this Lease and 
any balance thereof shall be returned to Tenant (or, at Landlord's option, to 
the last assignee of Tenant's interest hereunder) within the time specified 
in Civil Code Section 1950.7.

5.   REPAIRS

     (a) Subject to Paragraph 5(b), Landlord shall make all necessary repairs 
to the exterior walls, exterior doors, windows, corridors and other common 
areas of the Building and the Project and Landlord shall keep the Building 
and the Project in a safe, clean and neat condition, and use reasonable 
efforts to keep all equipment used in common with other tenants, such as 
elevators, plumbing, heating, air conditioning, intrabuilding network cabling 
and similar equipment, in good condition and repair. Except as provided in 
Paragraphs 14 and 15 hereof, there shall be no abatement of rent and no 
liability of Landlord by reason of any injury to or interference with or 
interruption of Tenant's business arising from the failure of any such 
equipment, the making of any repairs, alterations or improvements in or to 
any portion of the Building or Project or in or to fixtures, appurtenances 
and equipment therein. Tenant waives the right to make repairs at Landlord's 
expense under Section 1942 of the California Civil Code, or under any law, 
statute or ordinance now or hereafter in effect. Landlord shall have no 
obligation to repair until a reasonable time after receipt of notice or 
knowledge of the need for repair. The cost of all such work by Landlord shall 
be included in Operating Expenses pursuant to Paragraph 3.

    (b) Tenant agrees that it will make all repairs to the Premises and 
fixtures therein not required above to be made by Landlord and shall do all 
decorating, remodeling, alteration and painting required by Tenant during the 
term of this Lease. Tenant will pay for any repairs to the Premises, the 
Building or the Project made necessary by any negligence or carelessness of 
Tenant or its assignees, subtenants, employees of their respective agents or 
other persons permitted in the Building or on the Project by Tenant, or any 
of them, and will maintain the Premises, and will leave the Premises upon 
termination of this Lease in a safe, clean, neat and sanitary condition.

     (c) Tenant's repair and maintenance obligations pursuant to Paragraph 
5(b) shall extend to any non-Building standard equipment which is either (a) 
in place in or to serve solely the Premises upon execution of this Lease or 
(b) is installed by or for Tenant (whether by Landlord or Tenant) to serve 
solely the Premises. Such non-standard equipment includes, but is not limited 
to, any supplemental heating, ventilating and air conditioning equipment 
(whether or not located in the Premises), water heaters, dish washers and 
refrigerators. Moreover, Tenant's insurance and indemnification obligations 
pursuant to Paragraph 20 shall extend to all such non-standard equipment and 
to the use and malfunctioning of such equipment. If Landlord undertakes any 
repair or maintenance obligation of Tenant pursuant to Paragraph 5(b) (such 
as equipment located outside of but serving only the Premises), the cost of 
such repair or maintenance shall be reimbursed by Tenant to Landlord, as 
Additional Rent, within ten (10) days after Tenant's receipt of Landlord's 
invoice therefor.

6.   IMPROVEMENTS AND ALTERATIONS

     (a) Landlord shall have no construction obligation pursuant to this Lease
and Tenant shall take the Premises in its current "as-is" condition
without warranty or representation.

     (b) Landlord shall have the right, at any time, and without any liability
to Tenant, to change the arrangement and/or location of entrances or
passageways, doors and doorways, and corridors, elevators, stairs, toilets,

Tenant reasonable notice thereof, to change the name, number or
designation by which the Building or the Project is commonly known.

     (c) After the initial tenant improvements have been completed, Tenant 
shall not make any alterations, additions or improvements without the prior 
written consent of Landlord. All such alterations, additions and improvements

Landlord. All such alterations, additions and improvements (except movable 
furniture, furnishings and trade fixtures) shall become the property of 
Landlord and shall be surrendered with the Premises, as a part thereof, at 
the expiration or earlier termination of the term hereof. All such 
alterations, additions or improvements shall, however, be made by Tenant at 
Tenant's sole expense. Upon termination of the Lease, or, at Landlord's 
option, within thirty (30) days prior to the expiration of the Lease term, 
Tenant shall, upon demand by Landlord, at Tenant's sole cost and expense, 
forthwith remove any alterations, additions or improvements (except those 
made initially at the commencement of Tenant's possession of the Premises) 
made by Tenant and designated by Landlord to be removed, and repair and 
restore the Premises to their original condition, reasonable wear and tear 
excepted. If, at the termination of this Lease, Landlord is unable to 
reasonably provide the amount of space required for Tenant's ongoing 
operation, then Tenant may remove from the Premises the Liebert UPS System 
and the Airflow air conditioning unit which are currently located in the 
Premises for Tenant's use at its new location. Any personal property left on 
or in the Premises at the expiration or earlier termination of this Lease 
shall be disposed of by Landlord in the manner provided by law, including, 
without limitation, California Civil Code Section 1980 ET SEQ. Tenant 
releases Landlord of and from any and all claims and liability for damage to 
or destruction or loss of property left by Tenant upon the Premises at the 
expiration or other termination of this Lease and Tenant hereby indemnifies 
Landlord against any and all claims and liability with respect thereto. Tenant 
further waives all claims to all property (and the proceeds thereof) 
abandoned by Tenant and retained or disposed of by Landlord.

    (d) Tenant shall not commence work on any alteration, addition or 
improvement until and unless Landlord has received at least ten (10) days 
notice that such work is to commence. Tenant shall immediately reimburse 
Landlord for any expense incurred by Landlord in reviewing and approving the 
plans and specifications for such work or by reason of any faulty work done 
by Tenant or Tenant's contractors, or by reason of delays caused by such 
work, or by reason of inadequate cleanup, or which is otherwise incurred by 
Landlord to review the plans and specifications, and monitor and inspect the 
progress of such work. Tenant or its contractors will in no event be allowed 
to make any improvements to the Premises which could possibly affect any of 
the Building systems or to make any structural modification to the Building 
without first obtaining Landlord's consent, which Landlord can withhold in 
its sole and absolute discretion. All work by Tenant shall be scheduled 
through Landlord and shall be diligently and continuously pursued from the 
date of its commencement through its completion. In addition to the 
foregoing, and at Landlord's option, Tenant shall obtain a completion and/or 
performance bond in a form and by a surety acceptable to Landlord and in an 
amount not less than one and one-half (1 1/2) times the estimated cost of 
such alterations, additions or improvements.

     (e) All alterations, additions and improvements to the Premises made by 
Tenant shall comply with the plans therefor approved in advance by Landlord; 
provided, however, Landlord's approval or consent to any such work shall not 
impose any liability upon Landlord nor shall such approval infer that 
Landlord has expressed any opinion or made any warranty regarding the 
adequacy, sufficiency or legality of any such improvements. Such plans and 
any specifications associated therewith shall be prepared by an architect or 
interior designer approved in advance by Landlord. No such work shall proceed 
without Landlord's prior approval of (i) Tenant's contractor(s); (ii) 
certificates of insurance from a company or companies approved by Landlord, 
furnished to Landlord by Tenant's contractor, for combined single limit 
bodily injury and property damage insurance covering comprehensive general 
liability and automobile liability, in an amount not less than One Million 
Dollars ($1,000,000) per occurrence and endorsed to show Landlord as an 
additional named insured, and for workers' compensation as required by law 
(provided, however, nothing in this subparagraph shall release Tenant of its 
other insurance obligations hereunder); and (iii) detailed plans and 
specifications for such work. All such work by Tenant shall be done in a 
first-class workmanlike manner and in conformity with all applicable 
governmental requirements, with valid building permit(s) and/or all other 
permits or licenses when and where required, copies of which shall be 
furnished to Landlord before the work is commenced, and any work not 
acceptable to any governmental authority or agency having or exercising 
jurisdiction over such work, or not reasonably satisfactory to Landlord, 
shall be promptly replaced and corrected at Tenant's expense. All such work 
shall comply with all rules and regulations established by Landlord to ensure 
the safety, cleanliness and good order of the Building and the Project and 
its occupants, including but not limited to those relating to usage of 
elevators and loading docks, establishment of off-Premises staging areas, 
disposal of refuse and the hours of performing operations which result in the 
creation of noise, dust and odors. No such alterations, additions or 
improvements by Tenant shall incorporate therein any hazardous materials, as 
defined in Paragraph 9.

    (f) No antenna, satellite dish, microwave receiver or other receiving or
transmission equipment shall be installed by Tenant in or on the roof of
the Building or elsewhere in the Project except with the prior written
consent of Landlord which consent may be given or withheld by Landlord in
its sole and absolute discretion. Any such installation which may be
approved, shall be subject to such terms and conditions as are provided by
Landlord to Tenant at the time Landlord approves such installation.

7.   LIENS

     Tenant shall keep the Premises and the Building and Project free from 
any liens arising out of any work performed, materials furnished, or 
obligations incurred by or for Tenant. In the event that Tenant shall not, 
within thirty (30) days following the imposition of any such lien, cause the 
same to be released of record by payment or posting of a proper lien release 
bond, Landlord shall have, in addition to all other remedies provided herein 
and by law, the right, but not the obligation, to cause the same to be 
released by such means as it shall deem proper, including payment of or 
defense against the claim giving rise to such lien. All sums paid by Landlord 
and all expenses incurred by it in connection therewith shall create 
automatically an obligation of Tenant to pay an equivalent amount as 
additional rent, which additional rent shall be payable by Tenant within five 
(5) days after Tenant's receipt of Landlord's demand therefor with interest 
at the rate per annum determined pursuant to Paragraph 37 from date of 
payment by Landlord until paid by Tenant. Tenant agrees to indemnify and hold 
Landlord harmless from and against any and all claims for mechanics', 
materialmen's or other liens in connection with any alterations, repairs or 
any work performed, materials furnished or obligations incurred by or for 
Tenant. Nothing herein shall imply any consent by Landlord to subject 
Landlord's estate to liability under any mechanics' or other lien law. Tenant 
shall give Landlord adequate opportunity and Landlord shall have the right to 
post in or on the Premises such notices of nonresponsibility as are provided 
for in the mechanics lien laws of the state of California.

8.   USE OF PREMISES

     Tenant and any of its permitted assignees, sublessees or other occupants 
(collectively "Tenant Parties") shall use the Premises only for the 
purpose(s) set forth in Item 11 of the Basic Lease Provisions and shall not 
use or permit the Premises to be used for any other purpose without the prior 
written consent of Landlord. Without limiting the foregoing, Tenant and the 
Tenant Parties shall not use the Premises, nor permit the Premises to be 
used, for retail purposes nor shall Tenant or the Tenant Parties permit the 
Premises to be used by a governmental or quasi-governmental entity or 
agency (it being understood, however, that Landlord may lease to such an 
entity or agency if Landlord recaptures all or any portion of the Premises 
pursuant to Paragraph 16 below). Tenant shall not use or occupy the Premises 
in violation of law or of the certificate of occupancy issued for the 
Building, and shall, upon five (5) days' written notice from Landlord, 
discontinue any use of the Premises which is declared by any governmental 
authority having jurisdiction to be a violation of law or of such certificate 
of occupancy. Tenant shall comply promptly with any direction of any 
governmental authority having jurisdiction which shall, by reason of the 
nature of Tenant's use or occupancy of the Premises, impose any duty upon 
Tenant or Landlord with respect to the Premises or with respect to the use or 
occupancy thereof. Tenant shall not do or permit to be done anything which 
will invalidate or increase the cost of any fire, extended coverage or any 
other insurance policy covering the Building, the Project and/or property 
located therein and shall comply with all rules, orders, regulations and 
requirements of the Pacific Fire Rating Bureau or any other organization 
performing a similar function. Notwithstanding Paragraph 3, Tenant shall 
promptly upon demand reimburse Landlord, as additional rent, for the full 
amount of any additional premium charged for such policy by reason of 
Tenant's failure to comply with the provisions of this Paragraph, together 
with interest thereon from date of payment by Landlord to date of 
reimbursement by Tenant at the rate per annum determined pursuant to 
Paragraph 37. Such demand for reimbursement shall not be Landlord's exclusive 
remedy. Tenant shall not 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 the Project, or injure or annoy them, 
or use or allow the Premises to be used for any improper, immoral, unlawful 
or objectionable purpose, nor shall Tenant cause, maintain or permit any 
nuisance in, or about the Premises. Tenant shall not commit or suffer to be 
committed any waste in or upon the Premises. Landlord shall not be liable to 
Tenant for any other occupant's or tenant's failure to conduct itself in 
accordance with the provisions of this Paragraph 8, and Tenant shall not be 
released or excused from the performance of any of its obligations under the 
Lease in the event of any such failure.

     Without limiting any of its other obligations pursuant to this Paragraph 
8 or Paragraph 9, Tenant covenants and agrees to comply with all laws, rules, 
regulations and guidelines now or hereafter applicable to the Premises with 
respect to the disposal of water, trash, garbage and other matter (liquid or 
solid) generated by Tenant, the disposal of which is not otherwise the 
express obligation of Landlord under this Lease, including, but not limited 
to, laws, rules, regulations and guidelines with respect to recycling and 
other forms of reclamation (all of which are herein collectively referred to 
as "Waste Management Requirements"). Tenant shall comply with all rules and 
regulations established by Landlord from time to time to comply with Waste 
Management Requirements applicable to Landlord (i) as owner of the Premises 
and (ii) in performing Landlord's obligations under this Lease, if any. 
Tenant's obligations under this Paragraph 8 shall survive the expiration or 
termination of this Lease.

   Tenant shall indemnify, defend, protect and hold Landlord harmless from 
and against all liability (including costs, expenses and attorneys' fees) 
that Landlord may sustain by reason of Tenant's breach of its obligations 
under this Paragraph 8.

likelihood of a violation of Hazardous Materials Laws as a result of Tenant's 
Use of the Hazardous Materials and/or installation and operation of 
Equipment, and/or (iii) increasing the amount of the security deposit. 
Neither Landlord's consent nor Tenant's obtaining any Permits shall relieve 
Tenant of any of its obligations pursuant to this Paragraph 9. Landlord's 
granting of consent to one request to Use Hazardous Materials and/or install 
and operate Equipment shall not be deemed Landlord's consent to any other 
such request. If Landlord grants its consent to Tenant's request, no 
subtenant, assignee or successor of Tenant shall have the right to Use those 
Hazardous Materials or install or operate that Equipment without again 
complying with the provisions of this Paragraph 9(b)(ii).

asbestos or asbestos-containing materials.

     (c) Tenant shall deliver to Landlord, within thirty (30) days after 
Tenant's receipt of Landlord's written request, a written list identifying 
any Hazardous Materials that Tenant or its Agents then Uses or has Used 
within the last twelve (12) month period in the Project. Each such list shall 
state: (i) the use or purpose of each such Hazardous Material; (ii) the 
approximate quantity of each such Hazardous Material Used by Tenant; (iii) 
such other information as Landlord may reasonably require; and (iv) Tenant's 
written certification that neither Tenant nor its Agents have released, 
discharged or disposed of any Hazardous Materials in or about the Project, or 
transported any Hazardous Materials to or from the Project, in violation of 
any applicable Hazardous Materials Laws. Landlord shall not request Tenant to 
deliver a Hazardous Materials list more often than once during each twelve 
(12) month period, unless Landlord reasonably believes that Tenant or its 
Agents have violated the provisions of this Paragraph 9 (in which case (A) 
Landlord may request such lists as often as Landlord determines is necessary 
until such violation is cured, and (B) Tenant shall provide such lists within 
ten (10) days of each of Landlord's requests, or if an emergency exists, such 
lists shall be immediately provided).

     (d) Tenant shall furnish to Landlord copies of all notices, claims, 
reports, complaints, warnings, asserted violations, documents or other 
communications received or delivered by Tenant, as soon as possible and in 
any event within five (5) days of such receipt or delivery, with respect to 
any actual or alleged Use, disposal or transportation of Hazardous Materials 
in or about the Premises, the Building or the Project. Whether or not Tenant 
receives any such notice, claim, report, complaint, warning, asserted 
violation, document or communication, Tenant shall immediately notify 
Landlord, orally and in writing, if Tenant or any of its Agents knows or has 
reasonable cause to believe that any Hazardous Materials, or a condition 
involving or resulting from the same, is present, in Use, has been disposed 
of, or transported to or from the Premises, the Building or the Project other 
than is previously consented to by Landlord in strict accordance with 
Paragraph 9(b).

     (e) Tenant acknowledges that it, and not Landlord, is in possession and 
control of the Premises for purposes of all reporting requirements under any 
Hazardous Materials Laws. If Tenant or its Agents violate any provision of 
this Paragraph 9, then Tenant shall immediately notify Landlord in writing 
and shall be obligated, at Tenant's sole cost, to abate, remediate, clean-up 
and/or remove from the Project, and dispose of, all in compliance with all 
applicable Hazardous Materials Laws, all Hazardous Materials Used by Tenant 
or its Agents. Such work shall include, but not be limited to, all testing 
and investigation required by Landlord, Landlord's lender and/or ground 
lessor, if any, and any governmental authorities having jurisdiction, and 
preparation and implementation of any remedial action plan required by any 
governmental authorities having jurisdiction. All such work shall, in each 
instance, be conducted to the satisfaction of Landlord and all governmental 
authorities having jurisdiction. If at any time Landlord determines that 
Tenant is not complying with the provisions of this Paragraph 9(e), then 
Landlord may, without prejudicing, limiting, releasing or waiving Landlord's 
rights under this Paragraph 9, separately undertake such work, and Tenant 
shall reimburse all costs incurred by Landlord upon demand.

     (f) Landlord's right of entry pursuant to Paragraph 17 shall include the 
right to enter and inspect the Premises, and the right to inspect Tenant's 
books and records, to verify Tenant's compliance with, or violations of, the 
provisions of this Paragraph 9. Furthermore, Landlord may conduct such 
investigations and tests as Landlord or Landlord's lender or ground lessor 
may require. If Landlord determines that Tenant has violated the provisions 
of this Paragraph 9, or if any applicable governmental agency requires any 
such inspection, investigation or testing, then Tenant, in addition to its 
other obligations set forth in this Paragraph 9, shall immediately reimburse 
Landlord for all costs incurred therewith.

     (g) (i) Tenant shall indemnify, protect, defend (with legal counsel 
acceptable to Landlord in its subjective, good faith judgment) and hold 
harmless Landlord, its partners and its and their respective successors, 
assigns, partners, directors, officers, shareholders, employees, agents, 
lenders, ground lessors and attorneys, and the Project, from and against any 
and all Claims incurred by such indemnified persons, or any of them, in 
connection with, or as the result of: (A) the presence, Use or disposal of 
any Hazardous Materials into or about the Project, or the transportation of 
any Hazardous Materials to or from the Project, by Tenant or its Agents; (B) 
any injury to or death of persons or damage to or destruction of property 
resulting from the presence, Use or disposal of any Hazardous Materials into 
or about the Project, or the transportation of any Hazardous Materials to or 
from the Project, by Tenant or its Agents; (C) any violation of any Hazardous 
Materials Laws; and (D) any failure of Tenant or its Agents to observe the 
provisions of this Paragraph 9. Payment shall not be a condition precedent to 
enforcement of the foregoing indemnification provision. Tenant's obligations 
hereunder shall include, without limitation, and whether foreseeable or 
unforeseeable, all costs of any required or necessary testing, investigation, 
studies, reports, repair, clean-up, detoxification or decontamination of the 
Project, and the preparation and implementation of any closure, removal, 
remedial action or other required plans in connection therewith, and shall 
survive the expiration or earlier termination of the term of this Lease. For 
purposes of these indemnity provisions, any acts or omissions of Tenant, its 
assignees, sublessees, Agents or others acting for or on behalf of Tenant 
(regardless of whether they are negligent, intentional, willful, or unlawful) 
shall be strictly attributable to Tenant.

          (ii) If at any time after the initiation of any suit, action, 
investigation or other proceeding which could create a right of 
indemnification under Paragraph 9(g)(i) Landlord determines that Tenant is 
not complying with the provisions of Paragraph 9(g)(i), then Landlord may, 
without prejudicing, limiting, releasing or waiving the right of 
indemnification provided herein, separately defend or retain separate counsel 
to represent and control the defense as to Landlord's interest in such suit, 
action, investigation or other proceeding. Tenant shall pay all costs of 
Landlord's separate defense or counsel upon demand.

     (h) Upon any violation of the provisions of this Paragraph 9, Landlord 
shall be entitled to exercise any or all remedies available to a landlord 
against a defaulting tenant including, but not limited to, those set forth in 
Paragraph 26.

     (i) By its signature to this Lease, Tenant confirms that: (i) Landlord 
has not made any representation or warranty regarding the environmental 
condition of the Premises, the Building or the Project; and (ii) Tenant has 
conducted its own examination of the Premises, the Building and the Project 
with respect to Hazardous Materials and accepts the same "AS IS" and with no 
Hazardous Materials present thereon.

     (j) No termination, cancellation or release agreement entered into by 
Landlord and Tenant shall release Tenant from its obligations under this 
Paragraph 9 unless specifically agreed to by Landlord in writing at the time 
of such agreement.

     (k) Tenant's covenants and obligations under this Paragraph 9 shall also 
apply to any assignee or sublessee of Tenant, and to any such assignee's or 
sublessee's partners, officers, directors, shareholders, employees, agents, 
contractors and any other third parties entering upon the Project at the 
request or invitation of such assignee or sublessee.

10.  UTILITIES AND SERVICES

     (a) Provided that Tenant is not in default hereunder, Landlord agrees to 
furnish or cause to be furnished to the Premises, the utilities and services 
described, subject to the conditions and in accordance with the standards set 
forth below:

          (i) Landlord shall provide automatic elevator facilities to the 
     Building Monday through Friday, excepting therefrom all holidays 
     recognized by Landlord, hereinafter collectively referred to as 
     "generally accepted business days," from 8:00 a.m. to 6:00 p.m., 
     and on Saturdays from 8:00 a.m. to 12:00 noon, and have at least 
     one elevator available for use at all other times.

          (ii) On generally accepted business days from 8:00 a.m. 
     to 6:00 p.m. and on Saturdays from 8:00 a.m. to 12:00 noon (and at 
     other times for a reasonable additional charge to be fixed by 
     Landlord), Landlord shall ventilate the Premises and furnish air 
     conditioning when in the judgment of Landlord it is required for 
     the comfortable occupancy of the Premises during such days and 
     hours, subject to any requirements or standards relating to, among 
     other things, energy conservation, imposed or established by 
     governmental agencies or cooperative organizations. Landlord shall 
     make available at Tenant's expense after-hours power, including 
     light, and air conditioning to each floor of the Building which 
     shall be controlled by a digital control or other central control 
     system selected by Landlord. Minimum use of after-hours power and 
     air conditioning, the costs thereof and the prior notice required 
     for such services shall be determined from time to time by Landlord 
     and confirmed in writing to Tenant, as the same may change from 
     time to time.

                                                          LANDLORD'S   TENANT'S

                                       -8-



          (iii) Landlord shall furnish to the Premises at all times, 
     subject to interruptions beyond Landlord's control, electric 
     current as required by the building standard office lighting 
     (approximately two (2) watts per square foot at 277 volts) and 
     receptacles (approximately one (1) watt per square foot at 110 
     volts). At all times Tenant's use of electric current shall never 
     exceed the capacity of the feeders to the Building or the risers or 
     wiring installation.

          (iv) Landlord shall furnish water for drinking, cleaning and 
     lavatory purposes only.

          (v) Landlord shall provide janitorial services to the Premises 
     comparable to those provided in other first-class office buildings 
     in the vicinity of the Building, provided the same are used 
     exclusively as offices and are kept reasonably in order by Tenant. 
     Landlord shall not be responsible or liable for any act or omission 
     or commission on the part of the persons employed to perform said 
     janitorial services, which shall be performed at Landlord's 
     direction without interference by Tenant or Tenant's employees, 
     agents, contractors, licensees, directors, officers, partners, 
     trustees, visitors or invitees (collectively, "Tenant Parties"). If 
     the Premises are not used exclusively as offices, Tenant or persons 
     approved by Landlord shall keep the Premises clean and in order to 
     the satisfaction of Landlord, but at Tenant's sole expense. No 
     persons other than Tenant and those persons approved by Landlord 
     shall be permitted to enter the Building for the purpose of keeping 
     the Premises clean and in order. Tenant shall pay to Landlord the 
     cost of removal of any of Tenant's refuse and rubbish, to the 
     extent that the same exceeds the refuse and rubbish usually 
     attendant upon the use of the Premises as offices.

          (vi) Landlord shall replace, as necessary, the fluorescent 
     tubes in the building standard lighting fixtures installed by 
     Landlord. Tenant shall replace, as necessary, all bulbs and 
     fluorescent tubes in non building standard lighting fixtures, if 
     any, installed in the Premises. If Tenant shall fail to make any 
     such replacement within five (5) days after written notice from 
     Landlord, Landlord may make such replacement and charge the cost of 
     labor and materials involved therein to Tenant, as additional rent.

          (vii) Landlord shall provide at all times, subject to 
     interruption due to equipment failures, maintenance and/or repairs, 
     intrabuilding network cabling to permit connection of telephone 
     services from the Minimum Point of Entry as designated by Pacific 
     Bell to the telephone closet located on the floor of the Building 
     on which the Premises is located.

     (b) Landlord may impose a reasonable charge for any utilities and 
services, including without limitation, air conditioning, electric 
current and water, required to be provided by Landlord by reason of any 
use of the Premises at any time other than the hours from 8:00 a.m. to 
6:00 p.m. on generally accepted business days or the hours from 8:00 
a.m. to 12:00 noon on Saturdays or any use beyond what Landlord agrees 
to furnish as described above, or special electrical, cooling and 
ventilating needs created in certain areas by hybrid telephone 
equipment, computers and other similar equipment or uses. At Landlord's 
option, separate meters for such utilities and services may be installed 
for the Premises and Tenant, upon demand therefor, shall immediately pay 
Landlord for the installation, maintenance and repair of such meters.

     (c) Tenant agrees to cooperate fully at all times with Landlord and 
to abide by all regulations and requirements which Landlord may 
prescribe for the use of the above utilities and services. Any failure 
to pay any excess costs as described above shall constitute a breach of 
the obligation to pay rent under this Lease and shall entitle Landlord 
to the rights herein granted for such breach.

     (d) Landlord reserves the right in its sole and absolute discretion 
to reduce, interrupt or cease service of the heating, air conditioning, 
ventilation, elevator, plumbing, electrical systems, telephone systems 
(to the extent provided by Landlord) and/or utilities services of the 
Premises, the Building or the Project, for (i) the making of any 
repairs, additions, alterations or improvements to the Premises, 
Building or Project until said repairs, additions, alterations or 
improvements shall have been completed or (ii) any accident, breakage, 
strikes, lockouts or other labor disturbance or labor dispute of any 
character, governmental regulation, moratorium or other governmental 
action, inability by exercise of reasonable diligence to obtain 
electricity, water or fuel, or by any other cause beyond Landlord's 
reasonable control. In such event, Landlord shall not be liable for, and 
Tenant shall not be entitled to, any abatement or reduction of rent by 
reason of Landlord's failure to furnish any of the foregoing. Landlord 
shall not be in breach of this Lease and shall not be liable in damages 
(including but not limited to any damages, compensation or claims 
arising from any interruption or cessation of Tenant's business) or 
otherwise for failure, stoppage or interruption of any such service, nor 
shall the same be construed either as an eviction of Tenant, or work an 
abatement of rent, or relieve Tenant from the operation of any covenant 
or agreement. In the event of any failure, stoppage or interruption 
thereof, however, Landlord shall use reasonable diligence to resume 
service promptly where it is within Landlord's reasonable control to do 
so.

     (e) Landlord, in its sole and absolute discretion, may elect to 
contract for the services of individuals that will monitor the systems 
and operations of the Building and Project. In this connection, Landlord 
may also elect to station some of these individuals in the lobby of the 
Building. Such individuals are not security personnel and will not 
provide protective services to any of the tenants of the Building, 
including Tenant.

                                       -9-



     (f) Notwithstanding anything hereinabove to the contrary, Landlord 
reserves the right from time to time to make reasonable and nondiscriminatory 
modifications to the above standards for utilities and services.

     (g) Tenant shall pay for all telephone service to the Premises and shall 
contract directly with the providing company for such service, and Landlord 
shall have no responsibilities thereto.

11.  RULES AND REGULATIONS

     Tenant agrees to abide by all rules and regulations of the Building and 
the Project imposed by Landlord as set forth in Exhibit "C" attached hereto, 
as the same may be changed from time to time upon reasonable notice to 
Tenant. Any such change shall be effective upon delivery of a copy thereof to 
Tenant. These rules and regulations are imposed for the cleanliness, good 
appearance, proper maintenance, good order and reasonable use of the 
Premises, the Building and the Project, and as may be necessary for the 
enjoyment of the Building and the Project by all tenants and their clients, 
customers and employees. A breach of the rules and regulations shall not be 
grounds for termination of this Lease unless Tenant continues to breach the 
same after ten (10) days' written notice by Landlord; provided, however, that 
any such notice shall be in lieu of, and not in addition to, any notice 
required under Paragraph 26, below, or Section 1161, ET SEQ., of the 
California Code of Civil Procedure, as amended. Landlord shall not be liable 
to Tenant for the failure of any other tenant, its agents or employees, to 
conform to the rules and regulations.

12.  TAXES ON TENANT'S PROPERTY

     (a) Tenant shall be liable for and pay ten (10) days before delinquency, 
all taxes, levies and assessments levied against any personal property or 
trade fixtures placed by Tenant in or about the Premises, and, when possible, 
Tenant shall cause such personal property and trade fixtures to be assessed 
and billed separately from the Building and the Premises. If any such taxes, 
levies and assessments on Tenant's personal property or trade fixtures are 
levied against Landlord or Landlord's property or if the assessed value of 
the Building or the Project is increased by the inclusion therein of a value 
placed upon such personal property or trade fixtures of Tenant and if 
Landlord pays the taxes, levies and assessments based upon such increased 
assessment, which Landlord shall have the right to do regardless of the 
validity thereof, but only under proper protest if requested by Tenant, 
Tenant shall upon demand repay to Landlord, as additional rent, the taxes, 
levies and assessments so levied against Landlord, or the proportion of such 
taxes, levies and assessments resulting from such increase in the assessment, 
together with interest thereon from the date of payment by Landlord to the 
date of reimbursement by Tenant at the rate determined pursuant to Paragraph 
37. It is provided, however, that in any such event Tenant shall have the 
right, in the name of Landlord and with Landlord's full cooperation but 
without any cost to Landlord, to bring suit in any court of competent 
jurisdiction to recover the amount of any such taxes, levies and assessments 
so paid under protest, any amount so recovered to belong to Tenant.

     (b) If the tenant improvements in the Premises, whether installed and/or 
paid for by Landlord or Tenant and whether or not affixed to the real 
property so as to become a part thereof, are assessed for real property tax 
purposes at a valuation higher than the valuation at which tenant 
improvements conforming to Landlord's "building standard" in other space in 
the Building are assessed, then the real property taxes and assessments 
levied against Landlord or the Building or the Project by reason of such 
excess assessed valuation shall be deemed to be taxes levied against personal 
property of Tenant and shall be governed by the provisions of subparagraph 
(a) above. If the records of the County Assessor are available and 
sufficiently detailed to serve as a basis for determining whether said tenant 
improvements are assessed at a higher valuation than Landlord's "building 
standard," such records shall be binding on both Landlord and Tenant; 
otherwise the actual cost of construction shall be the basis for such 
determination.

13.  INTENTIONALLY OMITTED

14.  FIRE OR CASUALTY

     (a) In the event the Premises, or access to them, are wholly or 
partially destroyed by fire or other casualty covered by the form of fire and 
extended coverage insurance maintained by Landlord, Landlord shall rebuild, 
repair or restore the Premises and access thereto to substantially the same 
condition as when the same were furnished to Tenant, excluding any 
improvements installed by Tenant and any of Tenant's personal property, and 
this Lease shall continue in full force and effect. In the event, however, 
that the Building is so damaged or destroyed to the extent of more than 
one-third (1/3) of its replacement cost, or to any substantial extent by a 
casualty not so covered, Landlord may elect by written notice to Tenant given 
within twenty (20) days after the occurrence of the casualty to terminate 
this Lease in lieu of so restoring the Premises, in which event this Lease 
shall terminate as of the date of the occurrence of the casualty. Landlord 
shall in no event be obligated to make any repairs or replacement of any 
items other than those items installed by or at the


                                                          LANDLORD'S   TENANT'S

expense of Landlord. If the Premises are rendered totally or partially 
untenantable, rent shall abate during the period of reconstruction in the 
same proportion to the total rent as the portion of the Premises rendered 
untenantable bears to the entire Premises. Any such rental abatement shall 
not defeat or diminish Landlord's rights to recover upon any rental 
interruption insurance maintained by Landlord pursuant to Paragraph 20. In no 
event shall Tenant be entitled to any compensation or damages for loss of use 
of the whole or any part of the Premises or for any inconvenience occasioned 
by any such destruction, rebuilding or restoration of the Premises, the 
Building or access thereto. Tenant waives the provisions of California Civil 
Code Sections 1932(2) and 1933(4) and any present and future laws and case 
decisions to the same effect.

     (b) Notwithstanding anything to the contrary contained in Paragraph 
14(a) above, if the Premises or the Building or the Project is wholly or 
partially damaged or destroyed within the final twelve (12) months of the 
Term of this Lease, Landlord may, at its option, by giving Tenant notice 
within sixty (60) days after notice to Landlord of the occurrence of such 
damage or destruction, elect to terminate the Lease. Furthermore, upon 
termination of this Lease pursuant to this Paragraph 14(b), Tenant and 
Landlord hereby agree (except as expressly provided for otherwise in this 
Lease) to release each other from any and all obligations and liabilities 
with respect to the Lease except such obligations and liabilities which arise 
or accrue prior to such termination.

15. EMINENT DOMAIN

     (a) In case the whole of the Premises, or such part thereof as shall 
substantially interfere with Tenant's use and occupancy thereof, shall be 
taken by any lawful power or authority by exercise of the right of eminent 
domain, or sold to prevent such taking or threat of such taking, either 
Tenant or Landlord may terminate this Lease effective as of the date 
possession is required to be surrendered to said authority. Except as 
provided herein, Tenant shall not because of such taking assert any claim 
against Landlord or the taking authority for any compensation because of such 
taking, and Landlord shall be entitled to receive the entire amount of any 
award without deduction for any estate or interest of Tenant. In the event 
the amount of property or the type of estate taken shall not substantially 
interfere with Tenant's use of the Premises, Landlord shall be entitled to 
the entire amount of the award without deduction for any estate or interest 
of Tenant. In such event, Landlord shall promptly proceed to restore the 
Premises to substantially their condition prior to such partial taking, and a 
proportionate allowance shall be made to Tenant for the rent corresponding to 
the time during which, and to the part of the Premises of which, Tenant shall 
be so deprived on account of such taking and restoration. Any such rental 
abatement shall not defeat or diminish Landlord's rights to recover upon any 
rental interruption insurance maintained by Landlord pursuant to Paragraph 
20. Nothing contained in this Paragraph 15(a) shall be deemed to give 
Landlord any interest in, or prevent Tenant from seeking any award against 
the taking authority for, the taking of personal property and fixtures 
belonging to Tenant or for relocation or business interruption expenses 
recoverable from the taking authority. Landlord may, without any obligation 
to Tenant, agree to sell and/or convey to any taking authority the Premises, 
the Building, the Project or any portion thereof sought by such taking 
authority, free from this Lease and the rights of Tenant hereunder, without 
first requiring that any action or proceeding be instituted or pursued to 
judgment.

     (b) In the event of a temporary taking of the Premises or any part of 
the Premises and/or of Tenant's rights to the Premises or under this Lease, 
this Lease shall not terminate, nor shall Tenant have the right to any 
abatement of rent or of any other payments owed to Landlord pursuant to this 
Lease. Any award made to Tenant by reason of such temporary taking shall 
belong entirely to Tenant.

     (c) This Paragraph 15 shall be Tenant's sole and exclusive remedy in the 
event of a taking or condemnation. Tenant hereby waives the benefit of 
California Code of Civil Procedure Section 1265.130. Upon termination of the 
Lease pursuant to this Paragraph 15, Tenant and Landlord hereby agree (except 
as expressly provided for otherwise in this Lease) to release each other from 
any and all obligations and liabilities with respect to the Lease except such 
obligations and liabilities which arise or accrue prior to such termination.

16.  ASSIGNMENT AND SUBLETTING

     (a) Tenant shall not, either voluntarily or involuntarily or by 
operation of law, assign, sublet, mortgage or otherwise encumber all or any 
portion of its interest in this Lease or in the Premises or permit the 
Premises to be occupied by anyone other than Tenant or Tenant's employees 
without obtaining the prior written consent of Landlord, which consent shall 
be subject to the provisions of subsections (b) through (j) below. Any such 
attempted assignment, subletting, mortgage or other encumbrance without such 
consent shall be null and void and of no effect.

     (b) No assignment, subletting, mortgage or other encumbrance of Tenant's 
interest in this Lease shall relieve Tenant of its obligation to pay the rent 
and to perform all of the other obligations to be performed by Tenant 
hereunder. In this connection, any such assignment, sublease or encumbrance 
shall expressly provide that it is subject to the terms and provisions of 
this Lease. Moreover, any subletting by Tenant of any portion of the Premises 
shall be at a market rental rate and upon market terms and, if Landlord so 
requests, shall require that the assignee or sublessee remit directly to 
Landlord, on a monthly basis, all rent due to Tenant by

said assignee or sublessee. For this purpose, "market" shall mean a rental 
rate and terms comparable to the rental rate and terms then being offered by 
other landlords leasing comparable space in comparable commercial high-rise 
office buildings that are located within a one (1) mile radius of the 
Building. The acceptance of rent by Landlord from any other person shall not 
be deemed to be a waiver by Landlord of any provision of this Lease or to be 
a consent to any subletting, assignment, mortgage or other encumbrance. 
Consent to one sublease, assignment, mortgage or other encumbrance shall not 
be deemed to constitute consent to any subsequent attempted subletting, 
assignment, mortgage or other encumbrance.

     (c) If Tenant desires at any time to assign this Lease or to sublet the 
Premises or any portion thereof, it shall first notify Landlord of its desire 
to do so and shall submit in writing to Landlord (i) the name of the proposed 
subtenant or assignee; (ii) the nature of the proposed subtenant's or 
assignee's business to be carried on in the Premises, (iii) the terms and 
provisions of the proposed sublease or assignment and the proposed effective 
date thereof; and (iv) such financial information as Landlord may reasonably 
request concerning the proposed subtenant or assignee. The submission 
pursuant to clause (iii) shall include a copy of any agreement, escrow 
instructions or other document which contains or memorializes the terms and 
provisions of the transaction for which Landlord's consent is required. 
Similarly, if Tenant desires to mortgage or encumber its interest in this 
Lease, Tenant shall first supply to Landlord in writing such information as 
to such transaction as may be reasonably requested by Landlord.

     (d) As a condition to Landlord's consent to such assignment or 
subletting, Landlord shall be entitled to receive, in the case of a 
subletting, all rent (however denominated and paid) payable by the subtenant 
to Tenant in excess of that payable by Tenant to Landlord pursuant to the 
other provisions of this Lease and, in the case of an assignment, all 
consideration given, directly or indirectly, by the assignee to Tenant in 
connection with such assignment, less normal and usual costs incurred by 
Tenant in connection with such subletting or assignment amortized over the 
length of the term of such assignment or sublease. For the purposes of this 
subparagraph, the term "rent" shall mean all consideration paid or given, 
directly or indirectly, for the use of the Premises or any portion thereof. 
The term "consideration" shall mean and include money, services, property or 
any other thing of value such as payment of costs, cancellation of 
indebtedness, discounts, rebates and the like. "Normal and usual costs" shall 
only mean the following: broker's commission paid by Tenant to a broker 
independent of Tenant in connection with such assignment or subletting; legal 
fees incurred by Tenant in processing such assignment or subletting; 
out-of-pocket costs incurred by Tenant in advertising for an assignee or 
subtenant; and out-of-pocket costs incurred by Tenant to remodel or renovate 
the area subject to such subletting or assignment (which costs shall not 
exceed the cost of providing "Building Standard Improvements" in the 
quantities specified in Exhibit "B" for such assignee or subtenant). "Sublet" 
and "sublease" shall include a sublease as to which Tenant is sublessor and 
any sub-sublease or other sub-subtenancy, irrespective of the number of 
tenancies and tenancy levels between the ultimate occupant and Landlord, as 
to which Tenant receives any consideration, as defined in this subparagraph, 
and Tenant shall require on any sublease which it executes that Tenant 
receive the profit from all sub-subtenancies, irrespective of the number of 
levels thereof. Any rent or other consideration which is to be passed through 
to Landlord by Tenant pursuant to this subparagraph shall be paid to Landlord 
promptly upon receipt by Tenant and shall be paid in cash, irrespective of 
the form in which received by Tenant from any subtenant or assignee. In the 
event that any rent or other consideration received by Tenant from a 
subtenant or assignee is in a form other than cash, Tenant shall pay to 
Landlord in cash the fair value of such consideration.

     (e) At any time within thirty (30) days after Landlord's receipt of the 
last of the information specified in subparagraph (c) above, Landlord may by 
written notice to Tenant elect (i) to disapprove of such assignment or 
sublease, (ii) to sublease the Premises or the portion thereof so proposed to 
be subleased by Tenant, or to take an assignment of Tenant's leasehold 
estate hereunder, or such part thereof as shall be specified in said notice, 
on the same terms as those stated in this Lease and in turn sublease or 
assign to the proposed subtenant or assignee on the same terms as those 
offered by Tenant to the proposed subtenant or assignee, as the case may be; 
or (iii) to terminate this Lease as to the portion (including all) of the 
Premises so proposed to be subleased or assigned, with a proportionate 
abatement in the rent payable hereunder. It is provided, however, that if the 
proposed sublease will cover less than one half (1/2) of the area of the 
Premises covered by this Lease and will have a term (including all options to 
renew or extend the same) of less than two (2) years and will terminate more 
than two (2) years prior to the expiration date of this Lease, Landlord shall 
not be entitled to exercise option (ii) above, but may exercise option (i). 
Tenant shall, at Tenant's own cost and expense, discharge in full any 
commissions which may be due and owing as the result of any proposed 
assignment or subletting, whether or not the Premises are recaptured pursuant 
hereto and rented by Landlord to the proposed subtenant or assignee or any 
other tenant. If Landlord does not disapprove the proposed subletting or 
assignment in writing and does not exercise any option set forth in this 
subparagraph (e) within said thirty (30) day period, Tenant may within ninety 
(90) days after the expiration of said thirty (30) day period enter into a 
valid assignment or sublease of the Premises or portion thereof, upon the 
terms and conditions set forth in the information furnished by Tenant to 
Landlord pursuant to subparagraph (c) above. It is provided, however, that 
any material change in such terms shall be subject to Landlord's consent and 
rights of

termination and recapture as provided in this Paragraph and, provided 
further, that any amount to be paid by Tenant in connection with such 
subletting or assignment pursuant to subparagraph (d) above shall be paid to 
Landlord upon consummation of such transaction.

     (f) Landlord shall have the right to approve or disapprove any proposed 
assignee or subtenant. In exercising such right of approval or disapproval, 
Landlord shall be entitled to take into account any fact or factor which 
Landlord reasonably deems relevant to such decision, including but not 
necessarily limited to the following, all of which are agreed to be 
reasonable factors for Landlord's consideration:

          (i) The financial strength of the proposed assignee or 
     subtenant, including the adequacy of its working capital to pay all 
     expenses anticipated in connection with any proposed remodeling of 
     the Premises.

          (ii) The proposed use of the Premises by such proposed 
     assignee or subtenant and the compatibility of such proposed use 
     within the quality and nature of the other uses in the Building.

          (iii) Any violation which the proposed use by such proposed 
     assignee or subtenant would cause of any other rights granted by 
     Landlord to other tenants of the Building or the Project.

          (iv) Any adverse impact of the proposed use of the Premises by 
     such proposed assignee or subtenant upon the parking or other 
     services provided for Building or Project tenants generally.

          (v) Whether there then exists any default by Tenant pursuant to 
     this Lease or any non-payment or non-performance by Tenant under 
     this Lease which, with the passage of time and/or the giving of 
     notice, would constitute a default under this Lease.

          (vi) The business reputation, character, history and nature of 
     the business of the proposed assignee or subtenant.

          (vii) Whether the proposed assignee or subtenant is a person 
     with whom Landlord has negotiated for space in the Project during 
     the twelve (12) month period ending with the date Landlord receives 
     notice of such proposed assignment or subletting.

          (viii) Whether the proposed assignee or subtenant is a 
     governmental entity or agency.

Moreover, Landlord shall be entitled to be reasonably satisfied that each and 
every covenant, condition or obligation imposed upon Tenant by this Lease and 
each and every right, remedy or benefit afforded Landlord by this Lease is 
not impaired or diminished by such assignment or subletting. Landlord and 
Tenant acknowledge that the express standards and provisions set forth in 
this Lease dealing with assignment and subletting, including those set forth 
in this subparagraph (f) have been freely negotiated and are reasonable at 
the date hereof taking into account Tenant's proposed use of the Premises and 
the nature and quality of the Building and Project. No withholding of consent 
by Landlord for any reason deemed sufficient by Landlord shall give rise to 
any claim by Tenant or any proposed assignee or subtenant or entitle Tenant 
to terminate this Lease, to recover contract damages or to any abatement of 
rent. In this connection, Tenant hereby expressly waives its rights under 
California Civil Code Section 1995.310. Moreover, approval of any assignment 
of Tenant's interest shall, whether or not expressly so stated, be 
conditioned upon such assignee assuming in writing all obligations of Tenant 
hereunder.

     (g) All options to extend, renew or expand, all exterior sign rights and 
all reserved, reduced cost or free parking rights, in each case if any, 
contained in this Lease are personal to Tenant. Consent by Landlord to any 
assignment or subletting shall not include consent to the assignment or 
transfer of any such rights or options with respect to the Premises or any 
other special privileges or extra services granted to Tenant by this Lease, 
any addendum or amendment hereto or any letter agreement. All such options, 
rights, privileges and extra services shall terminate upon such subletting or 
assignment unless Landlord specifically grants the same in writing to such 
assignee or subtenant.

     (h) The voluntary or other surrender of this Lease by Tenant or a mutual 
cancellation hereof shall not work a merger, and shall, at the option of 
Landlord, terminate all or any existing subleases or subtenancies or shall 
operate as an assignment to Landlord of such subleases or subtenancies. 
Tenant agrees to reimburse Landlord for Landlord's reasonable costs and 
attorneys' fees incurred in connection with the processing and documentation 
of any such requested assignment, subletting, transfer, change of ownership 
or hypothecation of this Lease or Tenant's interest in and to the Premises.

     (i) Landlord shall be permitted to hire outside contractors to review 
all assignment and subletting documents and information and Tenant shall 
reimburse Landlord for the cost thereof, including reasonable attorneys' 
fees, on demand.

     (j) The foregoing notwithstanding, Tenant may assign this Lease at any 
time, or sublease all or part of the Premises, without receipt of Landlord's 
consent, to any entity which acquires all or part of Tenant, or which is 
acquired in whole or in part by Tenant, or which is controlled by Tenant, or 
which entity controls, Tenant (any such party hereinafter referred to as an 
"affiliate") so long as such transaction was not entered into as a subterfuge 
to avoid the obligations and restrictions of this Lease. In connection with 
any transaction of the type described in this subparagraph (j):

          (A) Any sublease shall be subject to all of the terms and 
provisions of this Lease and shall be terminable by Landlord upon the 
expiration or any earlier termination of this Lease, including a termination 
by mutual agreement of Landlord and Tenant.

          (B) In connection with any assignment, the assignee shall, within 
ten (10) days after receipt of written request from Landlord, execute and 
deliver to Landlord a written assumption of the obligations of Tenant 
pursuant to this Lease accruing from and after the effective date of the 
assignment and in form and substance reasonably satisfactory to Landlord.

          (C) No such assignment or subletting shall release Tenant from any 
of the obligations of Tenant hereunder, whether accruing prior to or 
subsequent to the effective date of such transaction.

          (D) No such transaction shall be accompanied by a change in use 
from that permitted pursuant to Paragraph 11 of the Basic Lease Provisions.

          (E) Within ten (10) days after the effective date of such 
transaction, Tenant shall notify Landlord in writing of such occurrence, the 
effective date thereof, the name of the assignee or subtenant, any change in 
the addresses for notice pursuant to this Lease and the facts which bring 
such transaction within the scope of this subparagraph (j).

17. ACCESS

     Landlord reserves and shall at any time and all times have the right to 
enter the Premises to inspect the same, to supply janitorial service and any 
other service to be provided by Landlord to Tenant hereunder, to submit said 
Premises to prospective purchasers, tenants or actual or prospective lenders, 
to post notices of non-responsibility, to use and maintain pipes and conduits 
in and through the Premises, and to alter, improve or repair the Premises or 
any other portion of the Building, all without being deemed guilty of an 
eviction of Tenant and without abatement of rent, and may for that purpose 
erect scaffolding and other necessary structures where reasonably required by 
the character of the work to be performed, provided that the business of 
Tenant shall be interfered with as little as is reasonably practicable. 
Landlord may enter by means of a master key without liability to Tenant for 
any damage caused by Landlord entering the Premises, except for damage to 
Tenant's personal property caused by any failure of Landlord to exercise due 
care. Tenant shall not disturb any notices or other items placed by Landlord 
in the Premises. Tenant hereby 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 occasioned 
thereby. For each of the aforesaid purposes, Landlord shall at all times have 
and retain a key with which to unlock all of the doors in, upon and about the 
Premises, excluding Tenant's vaults and safes, and Landlord shall have the 
right to use any and all means which Landlord may deem proper to open said 
doors in an emergency in order to obtain entry to the Premises. Any lock 
installed by Tenant shall be of a type and style designated by Landlord 
concurrently with such installation. Any entry to the Premises obtained by 
Landlord by any of said means shall not under any circumstances be construed 
or deemed to be a forcible or unlawful entry into, or a detainer of, the 
Premises, or any eviction of Tenant from the Premises or any portion thereof. 
No provision of this Lease shall be construed as obligating Landlord to 
perform any repairs, alterations or decorations except as otherwise expressly 
agreed to be performed by Landlord.

18.  SUBORDINATION; ATTORNMENT; ESTOPPEL CERTIFICATES; FINANCIAL STATEMENTS

     (a) This Lease and the rights of Tenant hereunder, at Landlord's 
election, shall be junior, subject, and subordinate to the lien of any ground 
or underlying lease, mortgage, deed of trust, and other security instrument 
of any kind now or hereafter covering the Premises, the Building or the 
Project, or any portion of any thereof, and to any and all advances made 
thereunder, interest thereon or costs incurred pursuant thereto (with respect 
to mortgages or deeds of trust) and any amendments, modifications, renewals, 
supplements, consolidations, replacements or extensions thereto. Such 
priority shall be established without the necessity of the execution and 
delivery of any further instruments on the part of Tenant to effect such 
subordination. Landlord or any ground lessor, mortgagee or beneficiary under 
a deed of trust may at any time cause such subordination by giving notice 
thereof to Tenant at least sixty (60) days before the subordination is to 
become effective. Notwithstanding the foregoing, Tenant covenants and agrees 
to (a) execute and deliver upon demand such further instruments evidencing 
such subordination of this Lease or subordination of such mortgage, deed of


                                                          LANDLORD'S   TENANT'S

trust or ground lease as may be requested by Landlord and (b) supply such 
financial information concerning Tenant as may be requested by any ground 
lessor or lender, prospective purchaser or Landlord, in connection with such 
subordination, within ten (10) business days after demand. If Tenant fails to 
execute such further instruments within ten (10) business days after demand, 
Landlord may execute such documents on behalf of Tenant as Tenant's 
attorney-in-fact. Tenant does hereby make, constitute and irrevocably appoint 
Landlord as Tenant's attorney-in-fact and in Tenant's name, place and stead, 
to execute such instruments in accordance with this subparagraph. In 
addition, Tenant's failure to execute such further instruments within ten 
(10) business days after demand shall constitute a material breach of this 
Lease. Notwithstanding subordination by Tenant to any existing or future 
lienholder, Tenant's right to quiet possession of the Premises shall not be 
disturbed so long as Tenant shall pay the rent and observe and perform all of 
the provisions of this Lease to be observed and performed by Tenant, unless 
this Lease is terminated pursuant to specific provisions relating thereto 
contained herein. In the event of the foreclosure of any such lien or 
encumbrance, Tenant shall attorn to the then owner who owns or acquires title 
to the Building or Project and will recognize such owner a Landlord under 
this Lease. Tenant hereby waives any right to terminate this Lease because of 
any such foreclosure.

     (b) Notwithstanding the foregoing, and without the consent of Tenant, 
the holder of any mortgage or deed of trust or the beneficiary thereunder 
shall have the right to elect to be subject and subordinate to this Lease, 
with such subordination to be effective upon such terms and conditions as 
such holder or beneficiary may direct and which are not inconsistent with the 
provisions of this Paragraph 18.

     (c) Tenant shall at any time and from time to time upon not less than 
twenty (20) days prior notice by Landlord, execute, acknowledge and deliver 
to Landlord a statement in writing (i) certifying that this Lease is 
unmodified and in full force and effect (or if there have been modifications, 
that the same is in full force and effect as modified and stating the 
modifications), and the dates to which the Basic Annual Rent, Additional Rent 
and other charges have been paid in advance, if any, (ii) stating whether or 
not to the best knowledge of Tenant, Landlord is in default in the 
performance of any covenant, agreement or condition contained in this Lease 
and, if so, specifying each such default of which Tenant may have knowledge 
and (iii) acknowledging (if true) the accuracy of such other facts as are 
included in such statement by Landlord. Any such statement delivered pursuant 
to this subparagraph may be relied upon by any prospective purchaser of the 
fee of the Building or the Project or any mortgagee, ground lessor or other 
like encumbrancer thereof or any assignee of any such encumbrancer upon the 
Building or the Project. If Tenant fails to deliver such statement within 
such time, such failure shall, at Landlord's option, be deemed to be Tenant's 
irrevocable appointment of Landlord as Tenant's special attorney-in-fact in 
connection with the preparation and execution of any such statement and such 
execution by Landlord as Tenant's attorney-in-fact shall be conclusive upon 
Tenant that (A) this Lease is in full force and effect, without modification 
except as may be represented by Landlord, (B) that there are no uncured 
defaults in Landlord's performance, (C) that with the exception of the amount 
indicated in Item 12 of the Basic Lease Provisions, not more than one month's 
Basic Annual Rent has been paid in advance and (D) that any other statements 
of fact included by Landlord in the statement are correct. Tenant shall be 
liable for all loss, cost or expense resulting from the failure of any ground 
lease, sale or funding of any loan caused by any material misstatement 
contained in any estoppel certificate supplied by Tenant or resulting from 
failure of Tenant to deliver any such statement.

     (d) In addition, and not in lieu of the foregoing, within ten (10) days 
after the Commencement Date, Tenant shall execute and deliver to Landlord a 
certificate substantially in the form of Exhibit "D" attached hereto, 
indicating thereon any exceptions thereto which Tenant claims to exist at 
that time. Failure of Tenant to execute and deliver such certificate within 
such time period shall constitute an acceptance of the Premises and the 
acknowledgment and agreement by Tenant that the statements included in 
Exhibit "D" are true and correct without exception.

19.  SALE BY LANDLORD

     In the event of a sale, transfer or conveyance by Landlord of the 
Building, the same shall operate to release Landlord from any and all 
liability under this Lease. Tenant's right to quiet possession of the 
Premises shall not be disturbed so long as Tenant shall pay the rent and 
observe and perform all of the provisions of this Lease to be observed and 
performed by Tenant, unless this Lease is terminated pursuant to specific 
provisions relating thereto contained herein. If any security deposit has 
been made by Tenant, Landlord may transfer the balance of such security 
deposit (after lawful deductions and in accordance with California Civil Code 
Section 1950.7), after notice to Tenant, to the purchaser, and thereupon 
Landlord shall be discharged from any further liability with respect thereto.

20.  NONLIABILITY AND INDEMNIFICATION OF LANDLORD; INSURANCE

     (a) LANDLORD'S NONLIABILITY. Subject to Paragraphs 20('s) and 21 below, 
Landlord and its partners, and their respective partners, officers, agents 
and employees shall not be liable for Tenant's loss of income or extra 
expense or for any damage to Tenant's property, nor for loss of damage to 
property by theft or otherwise, nor


                                                          LANDLORD'S   TENANT'S

for any injury or damage which may be sustained by the person, goods, wares, 
merchandise or property of Tenant, its employees, invitees or customers or 
any other person in or about the Premises caused by or resulting from any 
peril which may affect the Premises, including without limitation fire, 
explosion, falling plaster, steam, electricity, gas, water or rain, which may 
leak or flow from or into any part of the Premises, or from the breakage, 
leakage, obstruction or other defects of the pipes, sprinklers, wires, 
appliances, plumbing, air conditioning or lighting fixtures of the same, 
whether such damage or injury results from conditions arising upon the 
Premises or upon other portions of the Building, or from other sources. 
Landlord shall not be liable for any damages arising from any act or neglect 
of any other tenant or occupant of the Project or any of their officers, 
employees, agents, representatives, customers and invitees and Tenant hereby 
waives any such right it may have against Landlord. Tenant shall give prompt 
notice to Landlord in case of fire or accidents in the Premises or of defects 
therein or in the fixtures or equipment. Any claim, defense, or other right 
of Tenant arising in connection with this Lease or with negotiations before 
this Lease was signed shall be barred unless Tenant files an action or 
interposes a defense based thereon within one hundred eighty (180) days after 
the date of the alleged event on which Tenant is basing its claim, defense or 
right.

     (b) INDEMNIFICATION. Subject to Paragraphs 20('s) and 21 below, and to 
the fullest extent permitted by law, Tenant shall indemnify, hold Landlord 
harmless from and defend Landlord, its agents and employees against any and 
all claims, losses, costs, damages, expenses or liabilities, including 
without limitation reasonable attorney's fees and costs of defense, for death 
of or any injury or damage to any person or property whatsoever, when such 
death, injury or damage has been caused in part or in whole by the act, 
neglect, fault, or omission of Tenant, its assignees, sublessees, agents, 
servants, employees or invitees or which arises from Tenant's use of the 
Premises or the conduct of Tenant's business. Tenant shall further indemnify, 
hold Landlord harmless from and defend Landlord, it's agents and employees 
against and from any and all claims arising from any breach or default in the 
performance of any obligation on Tenant's part to be performed under the 
terms of this Lease. This indemnification provision shall not require payment 
as a condition precedent to recovery, and Tenant's defense obligation 
hereunder shall include the obligation, upon demand, to defend Landlord 
against any claim or action of the type herein specified by counsel 
reasonably satisfactory to Landlord. In addition, if any person not a party 
to this Lease shall institute any other type of action against Tenant in 
which Landlord, involuntarily and without cause, shall be made a party 
defendant and which is related to this Lease, Tenant shall indemnify, hold 
Landlord harmless from and defend Landlord from all liabilities by reason 
thereof.

     (c) TENANT'S INSURANCE. Tenant hereby agrees to maintain in full force 
and effect at all times during the term of this Lease, at its own expense,

          (i) Workers' Compensation coverage as required by law, including 
     United States Longshoremen and Harborworkers Act (if applicable),

     Landlord and any other parties in interest designated by Landlord as an 
     additional insured; (D) an endorsement stating, in substance, "such

     Tenant, or Tenant's operations and any insurance carried by Landlord, or 
     any other additional insured shall be non-contributory;" (E) with

     than $3,000,000 per annum available for occurrences at the Premises, if 
     such policy has an aggregate limit.

          (iii) Insurance providing protection against "All Risks" of 
     physical loss, including without limitation insurance against fire, 
     theft, burglary, structural collapse, sprinkler leakage, earthquake and 
     flood (if required by a lender holding a security interest in the 
     Project), vandalism and malicious mischief, in all amount sufficient to 
     cover the full cost of replacement (with no deductible for depreciation 
     and with the understanding that such amount shall be adjusted not more 
     frequently than on an annual basis) of all improvements and betterments 
     to the Premises, all of Tenant's fixtures, furnishings, equipment, 
     furniture, trade fixtures and other personal property located or used in 
     the Premises and loss of income or extra expense including losses

                                                          LANDLORD'S   TENANT'S

     coinsurance or contribution provisions and shall name Landlord and 
     the lending institution(s), if any, as additional insured's and/or loss 
     payable in accordance with such lender's or lenders' requirements. For 
     the purposes of this subparagraph (iii), the Premises shall consist of 
     the Rentable Area shown in the floor plan attached hereto as Exhibit 
     "A-1," and consist of the cubic space spanning from the floor slab to 
     the bottom surface of the floor slab of the floor immediately above the 
     Premises (the "upper slab"), without any offsets or deductions for 
     columns and other structural portions of the Building or vertical 
     penetrations that are included for the special use of Tenant. Such cubic 
     space shall include the plenum space which is bounded by the lower 
     surface of the upper slab and the suspended ceiling of the Premises. The 
     proceeds of such insurance, so long as this Lease remains in effect, 
     shall be used to repair or replace the improvements, trade fixtures and 
     personal property in the Premises so insured. Upon any termination of 
     this Lease pursuant to Paragraph 14(a) above, the proceeds of such 
     insurance relating to improvements to the Premises shall be the property 
     of Landlord.

          (iv) Loss of income or business interruption insurance providing 
     protection against any peril included within the classification "All 
     Risk," including but not limited to insurance against sprinkler leakage.

     The minimum limit of the coverage provided in division (ii) above shall 
be adjusted upward only at the expiration of each third (3rd) full calendar 
year as follows: Not less than sixty (60) days prior to the relevant 
adjustment date, Landlord shall request such insurance brokerage firm as is 
then placing insurance for Landlord (the "Reviewing Broker") to review 
Tenant's then existing liability insurance coverage, to review the then use 
of the Premises and the claims history with respect thereto and to recommend, 
in writing, the amount of coverage to be carried by Tenant pursuant to 
division (ii). Such recommendation shall be based upon the then use of the 
Premises and the liability claims history with respect to the Premises and 
shall be certified by the Reviewing Broker to be consistent with amounts of 
coverage generally recommended by such Reviewing Broker for similar types of 
tenants or users of property with uses similar to that of the Premises in the 
geographical area which includes the Premises. If the Reviewing Broker shall 
recommend an increase(s) in the amount of coverage then provided by Tenant 
under division (ii), Tenant shall promptly increase its coverage to the 
recommended amount(s). In no event shall there by any reduction in the amount 
of coverage provided by Tenant under division (ii) below the initial amounts 
set forth herein, notwithstanding any recommendation by the Reviewing Broker. 
The failure of the Reviewing Broker to require any additional insurance 
coverage shall not be deemed to relieve Tenant from any obligations under 
this Lease.

     (d) DEDUCTIBLES. Tenant may, with the written consent of Landlord, elect 
to have reasonable deductibles in connection with the policies of insurance 
required to be maintained by Tenant under subparagraph (c)(iii).

     (e) CERTIFICATES OF INSURANCE. Tenant shall deliver to Landlord at least 
thirty (30) days prior to the time such insurance is first required to be 
carried by Tenant, and thereafter at least thirty (30) days prior to the 
renewal date or expiration of each such policy, Certificates of Insurance 
evidencing the above coverage with limits not less than those specified 
above. Such Certificates, with the exception of Workers' Compensation, shall 
add Landlord and each of its partners, and its and their subsidiaries, 
affiliates, partners, officers, directors, agents, employees, lenders and 
other persons or entities designated by Landlord and having an insurable 
interest in the Premises as additional insured and shall expressly provide 
that the interest or same therein shall not be affected by any breach by 
Tenant of any policy provision for which such Certificates evidence coverage. 
Neither Landlord nor any other person or entity named as an additional 
insured pursuant to this subparagraph shall have any obligation under such 
policies, such as payment of premiums, giving of notices and the like. 
Further, all Certificates shall expressly provide that not less than thirty 
(30) days prior unqualified written notice shall be given to Landlord or 
Landlord's lender in the event of material alteration to, non-renewal of, or 
cancellation of the coverages evidenced by such Certificates. Notwithstanding 
the foregoing, Landlord may, at any time, from time to time, inspect and/or 
copy and approve any and all insurance policies required hereunder.

     (f) LANDLORD'S INSURANCE. Landlord shall at all times during the term of 
this Lease maintain in effect a policy or policies of (i) "All Risk" 
insurance, together with sprinkler leakage and vandalism and malicious 
mischief coverage, covering the Building and the Project, including 
Landlord's interest in all tenant improvements in the Premises, and (ii) 
Lessor's "Risk Only" Liability Insurance. Landlord may also, but shall not be 
required to, maintain flood and earthquake insurance with respect to the 
Project, rental interruption insurance assuring that the rent under this 
Lease will be paid to Landlord for a period of not less than twelve (12) 
months if the Premises are destroyed or rendered inaccessible by a risk 
insured against under the foregoing coverage, and any other types of 
insurance that Landlord, in its business judgment, may determine is necessary 
or desirable to obtain. The cost of all such insurance shall be included in 
the Operating Expenses to be reimbursed by Tenant to Landlord pursuant to 
Paragraph 3.

     (g) INCREASE IN COVERAGE. Upon demand, Tenant shall provide Landlord, at 
Tenant's expense, with such increased amount of existing insurance, and such 
other insurance in such limits, as Landlord may require and such other hazard 
insurance as the nature and condition of the Premises may require in the sole 
judgment of Landlord to afford Landlord adequate protection for risks of 
Tenant to be insured hereunder.


                                                          LANDLORD'S   TENANT'S

                                       -17-


     (h) NO CO-INSURANCE. If on account of the failure of Tenant to comply 
with the provisions of this Paragraph, Landlord or any additional insured is 
adjudged a coinsurer by its insurance carrier, then any loss or damage 
Landlord or such additional insured shall sustain by reason thereof shall be 
borne by Tenant and shall be immediately paid by Tenant upon receipt of a 
bill therefor and evidence of such loss.

     (i) INSURANCE LIMITS. Landlord makes no representation that the limits 
of liability specified to be carried by Tenant under the terms of this Lease 
are adequate to protect Tenant against Tenant's undertakings under this 
Lease. In the event Tenant believes that any such insurance coverage called 
for under this Lease is insufficient, Tenant shall provide, at its own 
expense, such additional insurance as Tenant deems adequate. In no event 
shall the limits of any coverage maintained by Tenant pursuant to this 
Paragraph 20 be considered as limiting Tenant's liability under this Lease.

     (j) LANDLORD'S NEGLIGENCE. Nothing contained herein shall operate to 
relieve Landlord from any loss, damage, injury, liability, claim, cost or 
expense which it is determined by a court of competent jurisdiction was 
proximately caused by its willful misconduct or its own sole negligence or 
the sole negligence of its agents or employees.

     (k) GENERAL REQUIREMENTS. All insurance required to be carried by Tenant 
hereunder shall be with companies rated A:X, or better, in the then most 
recent edition of Best's Insurance Guide and licensed to provide the relevant 
insurance in the State of California. Such insurance shall be primary 
insurance (and not "excess over") as respects Landlord and any other 
additional insured(s) designated by Landlord and not contributory with any 
other available insurance. All policies or such insurance shall each contain 
an unqualified provision that the insurer will not cancel, deny renewal or 
materially amend the coverage provided by such policy without first giving 
Landlord and any additional insured(s) thirty (30) days' prior written 
notice. All policies and certificates delivered by Tenant pursuant to this 
Paragraph shall contain liability limits not less than those set forth 
herein, shall list the additional insured(s) and shall specify all 
endorsements and special coverages required by this Paragraph. Any insurance 
required to be maintained by Tenant may be maintained by Tenant pursuant to 
so-called "blanket" policies of insurance so long as (i) the Premises is 
specifically identified therein (by rider, endorsement or otherwise) as 
included in the coverage provided, (ii) the limits of the policy arc 
applicable on a "per location" basis to the Premises and (iii) such policies 
otherwise comply with the provision of this Lease. The term "term of this 
Lease" shall mean, for the purposes of this Paragraph, the period commencing 
on the date Tenant is given access to the Premises for any purpose through 
the later of the expiration or termination of the Lease term or the date 
Tenant surrenders physical possession of the Premises to Landlord. With 
respect to the Comprehensive General Liability insurance required to be 
obtained by Tenant under this Lease, the foregoing general requirements are 
Subject to the specific requirements set forth in subparagraph (c)(ii), 
above.

     (l) In the event that Tenant fails to procure, maintain and/or pay for 
at the times and for the durations specified in this Lease, any insurance 
required by this Paragraph, or fails to carry insurance required by any 
governmental requirement, Landlord may (but without obligation to do so) at 
any time or from time to time, and without notice, procure such insurance and 
Tenant agrees to pay the sums so paid by Landlord together with interest 
thereon at the interest rate set forth in Paragraph 37(a) below, and any 
costs or expenses incurred by Landlord in connection therewith, within ten 
(10) days following Landlord's written demand to Tenant for such payment.

21.  WAIVER OF SUBROGATION

     Landlord and Tenant each hereby waives any and all rights of recovery 
against the other, and against any other tenant or occupant of the Building 
and the Project and against the officers, employees, agents, 
representatives, customers and invitees of such other party and of such other 
tenant or occupant of the Building and the Project for loss of or damage to 
such waiving party or its property or the property of others under its 
control, to the extent that such loss or damage is insured against under any 
policy of insurance required to be carried by such waiving party pursuant to 
(the provisions of this Lease (or any other policy of insurance carried by 
such waiving party in lieu thereof) at the time of such loss or damage. The 
foregoing waiver shall be effective whether or not a waiving party shall 
actually obtain and maintain the insurance which such waiving party is 
required to obtain and maintain pursuant to this Lease (or any substitute 
therefor). The policies of insurance which Landlord and Tenant are required 
to maintain under this Lease shall provide that the insurance company shall 
waive all right of recovery by way of subrogation against either Landlord or 
Tenant in connection with any damage covered by the subject policy.

22.  ATTORNEYS' FEES

     In the event of any legal action or proceeding brought by either party 
against the other arising out of this Lease or in which this Lease is 
asserted as a defense, the prevailing party shall be entitled to recover 
from the other party reasonable attorneys' fees incurred in such action in an 
amount determined by the court, in addition to its costs incurred in such 
action, and such amounts shall be included in any judgment rendered in
                                       
                                                          LANDLORD'S   TENANT'S

such action or proceeding. For purposes of this provision, in any unlawful 
detainer or other action or proceeding instituted by Landlord based upon any 
default or alleged default of Tenant hereunder, Landlord shall be deemed the 
prevailing party if (a) judgment is entered in favor of Landlord or (b) prior 
to trial or judgment Tenant shall pay all or any portion of the rent claimed 
by Landlord, eliminate the condition(s), cease the act(s) or otherwise cure 
the omission(s) claimed by Landlord to constitute a default by Tenant 
hereunder. If Landlord becomes involved in any litigation or dispute, 
threatened or actual, by or against anyone not a party to the Lease, but 
arising by reason of or related to any act of omission of Tenant or any of 
the Tenant Parties, Tenant agrees to pay Landlord's reasonable attorneys' 
fees and other costs incurred in connection with the litigation or dispute 
regardless of whether a lawsuit is actually filed.

23.  WAIVER

     No waiver by Landlord of any provision of this Lease or of any breach by 
Tenant hereunder shall be deemed to be a waiver of any other provision 
hereof, or of any subsequent breach by Tenant of the same or any other 
provision. Landlord's consent to or approval of any act by Tenant requiring 
Landlord's consent or approval shall not be deemed to render unnecessary the 
obtaining of Landlord's consent to or approval of any subsequent act of 
Tenant. Furthermore, any custom or practice which may develop between the 
parties in the administration of this Lease shall not be construed to waive 
or lessen the right of Landlord to insist upon the performance by Tenant in 
strict accordance with all of the terms, covenants, agreements, conditions, 
and provisions of this Lease. No act or thing done by Landlord or Landlord's 
agents during the term of this Lease shall be deemed an acceptance of a 
surrender of the Premises, unless done in a writing signed by Landlord. 
Tenant's delivery of keys to any employee or agent of Landlord shall not 
operate as a termination of this Lease or a surrender of the Premises unless 
done pursuant to a written agreement to such effect executed by Landlord. The 
acceptance of any rent by Landlord following a breach of this Lease by Tenant 
shall not constitute a waiver by Landlord of such breach (other than the 
failure to pay the particular rent so accepted) or any other breach unless 
such waiver is expressly stated in a writing signed by Landlord. The 
acceptance of any payment from a debtor in possession, a trustee, a receiver 
or any other person acting on behalf of Tenant or Tenant's estate shall 
not waive or cure a default under Paragraph 26(A)(vi) or waive the 
provisions of Paragraphs 16 or 25.

24.  NOTICES

     All notices, requests, payments, consents or approvals ("notices") which 
Landlord or Tenant may be required, or may desire, to serve on the other 
shall be in writing and may be served, by personal service or as an 
alternative to personal service, by mailing the same by registered or 
certified mail, postage prepaid and return receipt requested, addressed as 
set forth in Item 13 of the Basic Lease Provisions, or addressed to such 
other address or addresses as either Landlord or Tenant may from time to time 
designate to the other in the manner provided for herein. All notices shall 
be deemed effective upon receipt. If personally delivered, notices shall be 
deemed received at the time of delivery. If any notice is sent by mail, the 
same shall be deemed delivered and received on the date of receipt or refusal 
indicated on the return receipt. Any notice provided for herein may also be 
sent by facsimile transmission or by any reputable overnight courier so long 
as written confirmation of delivery of such notice is obtained by the 
sender. In either of these cases, a confirmation copy of such notice shall be 
sent by registered or certified mail, return receipt requested, and such 
notice shall be deemed to be received one day after it is sent.

25.  INSOLVENCY OR BANKRUPTCY

     In no event shall this Lease be assigned or assignable by operation of 
law and in no event shall this Lease be an asset or Tenant in any 
receivership, bankruptcy, insolvency, or reorganization proceeding.

26.  DEFAULTS AND REMEDIES

     (a) The occurrence of any of the following shall constitute a material 
default and breach of this Lease by Tenant:

         (i)   Any failure by Tenant to pay the rent or to make any other 
     payment required to be made by Tenant hereunder at the time specified for 
     payment. Landlord shall give Tenant three (3) days' written notice of any 
     such default, which notice shall be in lieu of, and not in addition to, 
     any notice required under Section 1161, ET SEQ., of the California Code 
     of Civil Procedure, as amended;

         (ii)  The abandonment of the Premises by Tenant. Abandonment is 
     herein defined to include, but is not limited to, any absence by Tenant 
     from the Premises for five (5) days or longer, without notice from 
     Landlord being required and regardless of whether Tenant is otherwise 
     in default under this Lease;
                                       
                                                          LANDLORD'S   TENANT'S

         (iii) Any failure by Tenant to observe and perform any other 
     provision of this Lease to be observed or performed by Tenant, where such 
     failure continues for ten (10) days (except where a different period of 
     time is specified in this Lease) after written notice by Landlord to 
     Tenant; provided, however, that any such notice shall be in lieu of, and 
     not in addition to, any notice required under Section 1161, ET SEQ., of 
     the California Code of Civil Procedure, as amended. If the nature of such 
     default is such that the same cannot reasonably be cured within such ten 
     (10) day period, Tenant shall not be deemed to be in default if Tenant 
     shall within such period commence such cure and thereafter diligently 
     prosecute the same to completion;

         (iv)  Tenant makes or has made or furnishes or has furnished any 
     warranty, representation or statement to Landlord in connection with this 
     Lease, or any other agreement to which Tenant and Landlord are parties, 
     which is or was false or misleading in any material respect when made or 
     furnished;

         (v)   Subject to the provisions of Paragraph 16(h) above, any 
     substantial portion of the assets of Tenant is transferred, or any 
     material obligation is incurred by Tenant, unless such transfer or 
     obligation is incurred in the ordinary course of Tenant's business, 
     or in good faith for fair equivalent consideration, or with Landlord's 
     consent; and/or

         (vi)  The making by Tenant of any general assignment for the benefit 
     of creditors; the filing by or against Tenant of a petition to have 
     Tenant adjudged a bankrupt or of a petition for reorganization or 
     arrangement under any law relating to bankruptcy (unless, in the case 
     of a petition filed against Tenant, the same is dismissed within sixty 
     (60) days); the appointment of a trustee or receiver to take possession 
     of substantially all of Tenant's assets located at the Premises or of 
     Tenant's interest in this Lease, where possession is not restored to 
     Tenant within sixty (60) days; the attachment, execution or other 
     judicial seizure of substantially all of Tenant's assets located at the 
     Premises or of Tenant's interest in this Lease, where such seizure is not 
     discharged within sixty (60) days; or Tenant's convening of a meeting of 
     its creditors or any class thereof for the purpose of effecting a 
     moratorium upon or composition of its debts.

     (b) In the event of any such default by Tenant, then in addition to any 
other remedies available to Landlord at law or in equity, Landlord shall have 
the immediate option to terminate this Lease and all rights of Tenant 
hereunder by giving written notice of such intention to terminate. In the 
event that Landlord shall elect to so terminate this Lease then Landlord may 
recover from Tenant:

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

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

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

         (iv)  any other amount necessary to compensate Landlord for all the
     detriment proximately caused by Tenant's failure to perform its obligations
     under this Lease or which in the ordinary course of things would be likely
     to result therefrom including any amount expended by Landlord to mitigate
     damages; plus

         (v)   the unamortized value of the Building Standard Work (as 
     described in Exhibit "B") made to the Premises, calculated by reference 
     to the length of the term of the Lease that would have remained had the 
     Lease not been terminated; plus

         (vi)  the amount of rent, if any, that is postponed or abated, as 
     well as the amount of any other rent or operating concession, any lease 
     take over obligation assumed by Landlord, any lease subsidy paid by 
     Landlord or any other bonus, lease cancellation payment, inducement or 
     concession for Tenant's entering into this Lease; and

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

     (c) As used in subparagraphs (b)(i) and (b)(ii) above, the "worth at the 
time of award" is computed by allowing interest at the rate determined 
pursuant to Paragraph 37 below. As used in subparagraph (b)(iii) above, the 
"worth at the time of award" is computed by discounting such amount at the 
discount rate of the Federal Reserve Bank of San Francisco at the time of 
award plus one percent (1%).

     (d) In the event of any default by Tenant, Landlord shall also have the 
right, with or without terminating this Lease, to re-enter the Premises and 
remove all persons and property from the Premises. Such property may be 
removed and stored in a public warehouse or elsewhere at the cost of and for 
the account of Tenant, all in accordance with applicable California law.

     (e) In the event of the abandonment of the Premises by Tenant or in the 
event that Landlord shall elect to re-enter as provided above or shall take 
possession of the Premises pursuant to legal proceedings or pursuant to any 
notice provided by law, then if Landlord does not elect to terminate this 
Lease as provided in this Paragraph 26, Landlord may from time to time, 
without terminating this Lease, either recover all rental as it becomes due 
or relet the Premises or any part thereof for such term or terms and at such 
rental or rentals and upon such other terms and conditions as Landlord in its 
sole discretion may deem advisable, with the right to make alterations and 
repairs to the Premises. Election by Landlord to proceed pursuant to this 
subparagraph shall be made upon written notice to Tenant and shall be deemed 
an election of the remedy described in California Civil Code Section 
1951.4 and, unless Landlord relets the Premises, Tenant shall have the right 
to sublet or assign subject to the prior written consent of Landlord. Such 
consent shall not be unreasonably withheld and shall be subject to all of 
the terms and provisions of Paragraph 16.

     (f) In the event that Landlord shall elect to so relet, then rentals 
received by Landlord from such reletting shall be applied: first, to the 
payment of any indebtedness other than rent due hereunder from Tenant to 
Landlord; second, to the payment of any cost of such reletting; third, to the 
payment of the cost of any alterations and repairs to the Premises; fourth, 
to the payment of rent due and unpaid hereunder; and the residue, if any, 
shall be held by Landlord and applied in payment of future amounts as the 
same may become due and payable hereunder. Should the rent for such 
reletting, during any month for which the payment of rent is required 
hereunder, be less than the rent payable during that month by Tenant 
hereunder, then Tenant shall pay such deficiency to Landlord immediately upon 
demand therefor by Landlord. Such deficiency shall be calculated and paid 
monthly. Tenant shall also pay to Landlord, as soon as ascertained, any costs 
and expenses incurred by Landlord in such reletting or in making such 
alterations and repairs not covered by the rentals received from such 
reletting.

     (g) No re-entry, removal of property or taking possession of the 
Premises by Landlord pursuant to this Paragraph 26 shall be construed as an 
election to terminate this Lease unless a written notice of such intention be 
given to Tenant or unless the termination thereof be decreed by a court of 
competent jurisdiction. Furthermore, neither Landlord's acts of maintenance 
or preservation NOR its efforts to relet NOR the appointment of a receiver to 
collect rents shall constitute a termination of Tenant's right to possession 
unless a written notice of such intention is provided by Landlord to Tenant. 
Notwithstanding any reletting without termination by Landlord because of any 
default by Tenant, Landlord may at any time after such reletting elect to 
terminate this Lease for any such default.

     (h) In any action for unlawful detainer commenced by Landlord against 
Tenant by reason of any default hereunder, the reasonable rental value of the 
Premises for the period of the unlawful detainer shall be the amount of rent 
reserved in this Lease for such period, unless Landlord or Tenant shall prove 
to the contrary by competent evidence. The rights and remedies reserved to 
Landlord herein, including those not specifically described, shall be 
cumulative and, except as otherwise provided by California statutory law in 
effect at the time, Landlord may pursue any or all of such rights and 
remedies, or any other right available at law or equity, at the same time or 
otherwise. Without limitation, Tenant acknowledges that Tenant's failure to 
timely comply with the requirements of Paragraph 18(a) may result in a 
lender refusing to loan Landlord funds or a buyer refusing to purchase the 
Building or Project on favorable terms (or at all), causing Landlord 
substantial monetary damages.

     (i) All covenants and agreements to be performed by Tenant under this 
Lease shall be performed by Tenant at Tenant's sole cost and expense and 
without any abatement of rent. If Tenant fails to pay any sum of money, other 
than rent, required to be paid by it or fails to perform any other act on its 
part to be performed, and such failure continues beyond any applicable grace 
period set forth in the Paragraph providing for such obligation (or if no 
grace period is set forth in such Paragraph, then the applicable grace 
period pursuant to this Paragraph 26), then in addition to any other remedies 
provided herein Landlord may but shall not be obligated so to do, without 
curing such default or waiving or releasing Tenant from any of its 
obligations, make any such payment or perform any such other act on Tenant's 
part, including the removal of any offending signs. Landlord's election to 
make any such payment or perform any such act on Tenant's part shall not give 
rise to any responsibility of Landlord to continue making the same or similar 
payments or performing the same or similar acts. Tenant shall, within ten 
(10) days after written demand therefor by Landlord, reimburse Landlord for 
all sums so paid by Landlord and all necessary incidental costs, together 
with interest thereon at the rate determined under Paragraph 37, accruing 
from the date of such payment by Landlord; and Landlord shall have the same 
rights and remedies in the event of failure by Tenant to pay such amounts as 
Landlord would have in the event of a default by Tenant in payment of rent.

     (j) Tenant hereby waives, for itself and all persons claiming by and 
under Tenant, all rights and privileges which it might have had under any 
present or future law, to redeem the Premises or to continue the Lease after 
being dispossessed or ejected from the Premises.

                                      -21-



27.  HOLDOVER

     Tenant shall surrender possession of the Premises immediately after 
the expiration of the Lease term or termination of the Lease. If Tenant or 
anyone claiming under Tenant holds over after the expiration or earlier 
termination of the term hereof without the express written consent of 
Landlord, Tenant shall (a) become a tenant at sufferance only at the greater 
of (i) two hundred percent (200%) of the Basic Annual Rent then in effect, or 
(ii) two hundred percent (200%) of the then prevailing market rent then in 
effect upon the date of such expiration or earlier termination (subject to 
adjustment as is provided in Paragraphs 2 and 3 hereof and prorated on a 
daily basis), and otherwise upon the terms, covenants and conditions herein 
specified, (including, without limitation, the payment of Additional Rent) so 
fir as applicable, (b) pay all damages sustained by Landlord by reason of 
such holding over and (c) indemnify, defend and hold Landlord harmless from and 
against any loss or liability resulting from such holding over, including, 
but not limited to, any amounts required to be paid to any tenant or 
prospective tenant who was to have occupied the Premises after said 
termination or expiration and any related attorneys' fees and brokerage 
commissions. Acceptance by Landlord of rent after such expiration or earlier 
termination shall not constitute a consent to a holdover hereunder, but shall 
create only a month-to-month tenancy terminable at the end of any calendar 
month by not less than ten (10) days written notice given by either party to 
the other party. Further, no payment of money by Tenant to Landlord after the 
etrmination of this Lease by Landlord, or after the giving of any notice of 
termination to Tenant by Landlord which Landlord is entitled to give Tenant 
under this Lease, shall reinstate, continue or extend the term of this Lease 
or shall affect any such notice given to Tenant prior to the payment of such 
money, it being agreed that after the service of such notice or the 
commencement of any suit by Landlord to obtain possession of the Premises, 
Landlord may receive and collect when due any and all payments owed by Tenant 
under the Lease, and otherwise exercise its rights and remedies. The making 
of any such payments by Tenant shall not waive such notice, or in any manner 
affect any pending suit or judgment obtained. The foregoing provisions of 
this Paragraph are in addition to and do not affect Landlord's right of 
re-entry or any other rights of Landlord hereunder or as otherwise provided 
by law.

28.  CONDITION OF PREMISES

     Tenant acknowledges that neither Landlord nor any agent of Landlord has 
made any representation or warranty with respect to the Premises, the 
Building or the Project or with respect to the suitability of any part of the 
Project for the conduct of Tenant's business. The taking of possession of the 
Premises by Tenant shall conclusively establish that the Premises and the 
Building were at such time in good and sanitary order, condition and repair. 
Landlord and its agents shall not be liable for any latent defect in the 
Premises or in the Building. Tenant shall give prompt notice to Landlord in 
case of fire or accidents in the Premises or in the Building, or of defects 
therein or in the fixtures and equipment.

29.  QUIET POSSESSION

     Upon Tenant's paying the rent hereunder and observing and performing all 
of the covenants, conditions and provisions on Tenant's part to be observed 
and performed hereunder, Tenant shall have quiet possession of the Premises 
for the entire term hereof, subject to all the provisions of this Lease.

30.  TENANT'S SIGNS

     (a) Tenant may, at its sole cost and expense, place its signs displaying 
its logo and graphics on the entrance doors to the Premises and in hallways 
or elevator lobbies on floors wholly leased by Tenant. On partial floors 
leased by Tenant, Tenant, at its sole cost and expense, may place its signs 
on entrance doors to the Premises provided the number, size, color, style, 
material and location of such signs conform to Landlord's graphics program 
for the Building and Landlord shall place directional signs to the Premises, 
at Tenant's expense, at a location determined by Landlord.

     (b) Landlord at its own cost and expense shall place a directory board 
in the Building lobby. Landlord shall cause Tenant's name to be affixed 
thereto, at Tenant's cost.

     (c) Unless specifically set forth to the contrary in an addendum to 
this Lease, Tenant shall not place any sign on the exterior of the Building, 
or within the Building if such sign may be seen from outside of (he Building 
or on any Building sign monument or other device constructed for the 
placement of tenant signs.

     (d) All Tenant signs installed by Landlord or Tenant shall comply with 
all applicable requirements of all governmental authorities having 
jurisdiction and shall be installed in a good and workmanlike manner. Such 
signs shall be maintained and kept in good repair at Tenant's sole cost and 
expense.
                                       
                                                          LANDLORD'S   TENANT'S

31.  CONFLICT OF LAWS

     This Lease shall be governed by and construed pursuant to the laws of 
the State of California, and the venue of any action or proceeding under 
this Lease shall be Orange County, California.

32.  COMMON FACILITIES; PARKING

     Tenant shall have the non-exclusive right, in common with Landlord and 
other tenants and occupants of the Project and their employees, agents and 
business visitors, to the use of all common facilities which constitute a 
part of the Project, subject to such reasonable rules and regulations 
relating to such use as Landlord may from time to time establish. Common 
facilities located within the Building include any building lobby, elevators, 
rest rooms, stairways and stairwells, elevator lobbies and all common 
entrances, corridors, passageways and serviceways which are not located 
within the Premises of Tenant or the premises of another tenant of the 
Building. Common facilities located outside of the Building include 
landscaping, hardscaping, a parking structure (the "Project Parking 
Structure"), all sidewalks, driveways, vehicle and pedestrian entrances and 
accessways, loading docks, truck tunnels, truck parking and truck turn-around 
areas, vehicle and pedestrian ramps serving the Project, and any pedestrian 
walkway connecting the Building and the Project Parking Structure. The common 
facilities located outside of the Building but included within the 
definition of the Project are those areas which are depicted on Exhibit 
"A-3" attached hereto. Landlord may make changes at any time and from time to 
time to the common facilities, without any liability to Tenant, and no such 
change shall entitle Tenant to any abatement of rent. Landlord shall at all 
times have the sole and exclusive control of the common facilities.

     Tenant shall keep all common facilities free and clear of any 
obstructions created or permitted by Tenant or resulting from Tenant's 
operations and shall not conduct an assembly on the common facilities without 
Landlord's prior consent. Nothing herein shall affect the right of Landlord 
at any time to remove any persons not authorized to use the common facilities 
or to prevent the use of such facilities by unauthorized persons. Landlord 
reserves the right, from time to time, to (A) make alterations in or 
additions to file common facilities, including without limitation, 
constructing new structures or changing the location, size, shape and/or 
number of the driveways, entrances, parking spaces, parking areas, loading 
and unloading areas, landscape areas and walkways, (B) close temporarily any 
of the common facilities of the Project for maintenance purposes as long as 
reasonable access to the Premises remains available, (C) designate property 
to be included in or eliminate property from the common facilities of the 
Project, and (D) use the common facilities of the Project while engaged in 
making alterations in or additions or repairs to the Project.

     Tenant shall have such parking rights in and to parking contracts for 
spaces located in the Project Parking Structure as are set forth in the 
Parking Agreement attached hereto as Exhibit "E." All agreements by Tenant 
and Tenant's employees for monthly usage of spaces shall be made directly 
with the operator of the Project Parking Structure.

33.  SUCCESSORS AND ASSIGNS

     Except as otherwise provided in this Lease, all of the covenants, 
conditions and provisions of this Lease shall be binding upon and shall inure 
to the benefit of the parties hereto and their respective heirs, personal 
representatives, successors and assigns.

34.  BROKERS

     Tenant warrants that it has had no dealings with any real estate broker 
or agent in connection with the negotiation of this Lease, excepting only 
the broker named in Item 10 of the Basic Lease Provisions ("Broker"), 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. Landlord covenants 
and agrees to pay all real estate commissions due in connection with this 
Lease to Broker as follows: (i) Landlord shall pay to Broker an amount equal 
to four percent (4%) of Basic Annual Rent and Additional Rent for the first 
twelve (12) months of the term of this Lease within ten (10) days of full 
execution and delivery or this Lease, and (ii) provided Tenant has not been 
in default of the Lease, Landlord shall pay to Broker an amount equal to 
four percent (4%) of Basic Annual Rent and Additional Rent for the second 
twelve (12) months of the term of this Lease within ten (10) days of the 
end of the seventeenth (17th) month of the term. Tenant agrees to pay and 
hold Landlord harmless from and defend Landlord against any cost, expense or 
liability for any compensation claimed by any broker, finder or agent other 
than Broker employed or claiming to have been employed by Tenant in 
connection with this Lease or with the negotiation of this Lease. Landlord 
and Tenant acknowledge that payment shall not be a condition precedent to 
recovery upon the foregoing indemnification provision.

                                       
                                                          LANDLORD'S   TENANT'S

                                                            H.T.S.
                                      -23-



35.  NAME

     Tenant shall not, without the written consent of Landlord, use the 
name, insignia or logotype of the Building or the Project for any purpose 
other than as the address of the business to be conducted by Tenant in the 
Premises, and in no event shall Tenant acquire any rights in or to such name, 
insignia and/or logotype. Furthermore, Tenant shall not use any picture of 
the Building or Project in its advertising, stationery or in any other 
manner. Tenant shall, when referring to the Building, refer to the Building 
by the name or address assigned thereto, from time to time, by Landlord and 
shall refer to its location as the "the Offices at South Coast Plaza." 
References to the Building and its location shall not be made by Tenant in 
any other manner. Landlord expressly reserves the right, in its sole and 
absolute discretion, at any time to change the name, insignia, logotype or 
street address of the Building or the Project without in any manner being 
liable to Tenant.

36.  EXAMINATION OF LEASE

     Submission of this instrument for examination, negotiation or signature 
by Tenant does not constitute an offer to lease or a reservation of the 
Premises for Tenant or an option for Tenant to lease the Premises, and it is 
not effective as a Lease or otherwise until at least one counterpart, duly 
executed by authorized persons of Landlord and Tenant, has been delivered to 
each party thereto. Without limiting the generality of the foregoing, Tenant 
acknowledges that this Lease and any material amendments hereto are subject 
to the approval of Landlord's lender with respect to the Project. Promptly 
upon execution of this Lease by Tenant, Landlord shall submit the same to its 
lender for approval. Delivery by Landlord to Tenant of a copy of this Lease 
or of any amendment hereto fully executed by Landlord and Tenant shall 
constitute notice to Tenant that Landlord has obtained the approval of its 
lender with respect to this Lease or such amendment.

37.  INTEREST ON TENANT'S OBLIGATIONS; LATE CHARGE

     (a) Any amount due from Tenant to Landlord which is not paid when due 
shall bear interest at the maximum rate per annum which Landlord is permitted 
by law to charge, from the date such payment is due until paid, but the 
payment of such interest shall not excuse or cure any default by Tenant under 
this Lease. Such rate shall remain in effect after the occurrence of any 
breach or default hereunder by Tenant to and until payment of the entire 
amount due.

     (b) In the event Tenant is more than ten (10) days late in paying any 
installment of rent due under this Lease, Tenant shall pay Landlord a late 
charge equal to five percent (5%) of the delinquent installment of rent, 
provided that in no event shall the amount of such late charge be less than 
One Hundred Dollars ($100.00). The parties agree that it would be impractical 
or extremely difficult to fix Landlord's actual damages due to a late payment 
by Tenant and that the amount of such late charge represents a reasonable 
estimate of the cost and expense that would be incurred by Landlord in 
processing each delinquent payment of rent by Tenant and that such late 
charge shall be paid to Landlord as liquidated damages for each delinquent 
payment pursuant to California Civil Code Section 1671. The parties further 
agree that the payment of late charges and the payment of interest provided 
for in subparagraph (a) above are distinct and separate from one another in 
that the payment of interest is to compensate Landlord for the use of 
Landlord's money by Tenant, while the payment of a late charge is to 
compensate Landlord for the additional administrative expense incurred by 
Landlord in handling and processing delinquent payments. It is understood 
that the payment of any late charge by Tenant and the acceptance thereof by 
Landlord shall not be deemed a waiver by Landlord of its rights regarding any 
default by Tenant under this Lease.

38.  TIME

     Time is of the essence of this Lease with respect to the performance of 
every provision of this Lease in which time of performance is a factor.

39.  DEFINED TERMS AND MARGINAL HEADINGS

     The words "Landlord" and "Tenant" as used herein shall each include the 
plural as well as the singular and, when applicable, shall refer to actions 
taken by their respective representatives. If more than one person is named 
as Tenant the obligations of such persons are joint and several. The headings 
to the Paragraphs of this Lease are not a part of this Lease and shall have 
no effect upon the construction or interpretations of any part hereof.

40.  PRIOR AGREEMENTS; SEPARABILITY

     This Lease and the exhibits and any addenda hereto contain all of the 
agreements of the parties hereto with respect to any matter covered or 
mentioned in this Lease, and no prior agreement, understanding or 
representation pertaining to any such matter shall be effective for any 
purpose. No provision of this Lease may be amended or added to except by an 
agreement in writing signed by the parties hereto or their respective 
successors in interest. No verbal agreement or implied covenant shall be held 
to vary the terms hereof, any statute, law or custom to the contrary 
notwithstanding. No employee or agent of Landlord shall have authority, by 
letter, memorandum or other written communication, to amend, vary or delete 
any provision of this Lease or any exhibit hereto, unless such written 
instrument bears the signature of Landlord. If any term or provision of this 
Lease the deletion of which would not adversely affect the receipt of any 
material benefit by either party hereunder shall be held invalid, illegal or 
unenforceable to any extent, the remainder of this Lease shall not be 
affected thereby and each term and provision of this Lease shall be valid and 
enforceable to the fullest extent permitted by law.

41.  TRAFFIC AND ENERGY MANAGEMENT

     (a) Tenant and its employees shall comply with South Coast Air Quality 
Management District Regulation 15 and any other environmental regulation 
and/or program now or hereafter applicable to the Project. Landlord and 
Tenant agree to cooperate and use their best efforts to participate in 
governmentally mandated and voluntary traffic management programs generally 
applicable to businesses located in Costa Mesa, California or to the Project 
and, initially, shall encourage and support van and car pooling by office 
workers and service employees and shall encourage and support staggered and 
flexible working hours for employees to the fullest extent permitted by the 
requirements of Tenant's business. Neither this Paragraph nor any other 
provision in this Lease, however, is intended to or shall create any rights 
or benefits in any other person, firm, company, governmental entity or the

     (b) Landlord and Tenant agree to cooperate and use their best efforts to

conservation association to which Landlord is a party concerning energy 
management.

     (c) All costs, fees and assessments and other charges paid by Landlord 
to any governmental authority or voluntary association in connection with any 
program of the types described in this Paragraph, and all costs and fees paid 
by Landlord to any governmental authority, voluntary association or third 
party pursuant to or to implement any such program, shall be included in

specifically listed in such Paragraph. Any breach by Tenant of any of its 
covenants in this Paragraph 41 may result in penalties or fees being assessed 
against Landlord or the Project. These penalties or fees shall not be part of

be payable by Tenant on demand of Landlord.

42.  CORPORATE/PARTNERSHIP/TRUST AUTHORITY

     Each individual executing this Lease on behalf of Landlord and Tenant 
represents and warrants that the execution and delivery of this Lease on

may reasonably request.

     Any diminution or shutting off of light, air or view by any structure

virtue of a strike, lockout, laws, rules, orders, ordinances, directions, 
regulations or requirements of any federal, state, county or municipal 
authority, labor trouble or any other cause whatsoever beyond Landlord's 
control, nor shall Tenant's rent be abated by reason of such inability on the

from any public corridors or other public areas on such floor, and the 
centerline of all walls separating such premises from other areas leased or 
to be leased to other tenants on such floor, and provided further that the

                             [TENANT CONSTRUCTS]

     In connection with the lease to which this Work Letter is attached (the 
"Lease"), Landlord and Tenant hereby agree to the terms and conditions set 
forth in this Work Letter relating to the construction of the tenant 
improvements in the Premises ("Tenant's Work"). This Work Letter is 
essentially organized chronologically and addresses the issues of the 
construction of the Premises, in sequence, as such issues will arise during 
the actual construction of the Premises. All capitalized terms used but not 
defined herein shall have the meanings given such terms in the Lease.

     1.  GENERAL.

         (a) The purpose of this Agreement is to set forth how Tenant's Work 
(as defined in Paragraph 5 below) in the Premises is to be constructed, who 
will undertake the construction of Tenant's Work, who will pay for the 
construction of Tenant's Work, and the time schedule for completion of the 
construction of Tenant's Work.

         (b) Except as defined in this Agreement to the contrary, all terms 
utilized in this Agreement shall have the same meanings ascribed to them in 
the Lease. When services, consents or approvals are to be provided by or on 
behalf of Landlord, the term "Landlord" shall include Landlord's agents, 
contractors, employees and affiliates.

         (c) The provisions of the Lease, except where clearly inconsistent or
inapplicable to this Agreement, are incorporated into this Agreement.

         (d) Tenant's Work shall be constructed pursuant to this Agreement by 
Tenant and at Tenant's sole expense.

     2.  COMMENCEMENT DATE. The "Commencement Date" of the Lease shall be as
determined pursuant to Item 8 of the Basic Lease Provisions of the Lease
and this Paragraph 2. That date has been determined based upon the
following:

         (a) DESIGN PERIOD. As provided in Paragraph 3(b) below, Landlord 
shall provide to Tenant (i) the Base Building Plans (as defined in Paragraph 
3.B. below) for the Building and the Premises sufficient to allow Tenant to 
prepare the Working Drawings (as defined in Paragraph 3(d) below) and (ii) 
all rules, regulations, instructions and procedures promulgated by Landlord 
with respect to tenant design and/or construction in the Building (the 
"Building Requirements"). Tenant shall submit for Landlord's approval the 
Space Plan for Tenant's Work in accordance with Paragraph 3(c) below. 
Subsequent to approval of the Space Plan for Tenant's Work and pursuant to 
the terms of Paragraph 3 below, Tenant shall prepare and submit for 
Landlord's approval the Working Drawings, the Engineering Drawings (as 
defined in Paragraph 3(e) below), and the Final Plans (as defined in 
Paragraph 3(f) below), and shall also prepare and submit for Landlord's 
approval a schedule of special finishes required by Tenant. Tenant shall 
thereafter obtain all governmental approvals and permits required for Tenant 
to commence Tenant's Work.

         (b) CONSTRUCTION AND MOVE-IN PERIOD. Landlord shall deliver to 
Tenant and its Contractor (as defined below) access to the Premises (and any 
other required portions of the Building and the Project) commencing as set 
forth in Paragraph 1 of the Lease Tenant shall complete all Tenant's Work in 
Compliance with all applicable laws, statutes, codes, rules and regulations 
(collectively, "Laws"). Tenant shall also obtain the appropriate permits 
necessary to allow Tenant to commence to construct Tenant's Work continuously 
and without interruption. Such period includes the time for Tenant, as a part 
of Tenant's Work, to install in the Premises Tenant's freestanding work 
stations, fixtures, furniture, equipment and telecommunication and computer 
cabling systems, and also includes the time for Tenant to move into the 
Premises.

         (c) DELAY OF COMMENCEMENT DATE. Notwithstanding anything to the 
contrary contained in the Lease or this Agreement, the date stated in Item 8

at the Project for other tenants.

     3.   DESIGN OF TENANT'S WORK. Tenant shall arrange for design of 
Tenant's Work in accordance with the following:

          (a) SELECTION OF DESIGNER AND ENGINEER. In connection with the design

and shall use an engineer designated by Landlord ("Engineer") who will 
perform the work required of it hereunder at competitive rates. The Designer 
and the Engineer shall each be familiar with all applicable Laws and Building 
Requirements to the extent such Building Requirements are provided to Tenant 
within the time specified in Paragraph 3(b) below. The Designer shall be 
selected by Tenant subject to Landlord's consent, which consent shall not be 
unreasonably withheld so long as each person or firm has all required state 
and local licenses and reasonable experience with projects of the size and 
scope of Tenant's Work. Such required approval shall be deemed given unless 
Landlord shall disapprove such person or firm by written notice to Tenant 
given within five (5) business days after Landlord's receipt of written 
notice from Tenant to Landlord identifying such person of firm and 
accompanied by a written statement as to the experience or such person or 
firm. This procedure shall be repeated until the Designer is finally 
approved, or deemed approved by Landlord.

          (b) BASE BUILDING PLANS. Landlord shall deliver to Tenant (i) 
instructions and Building plans and specifications (the "Base Building

          (c) PREPARATION AND APPROVAL OF SPACE PLAN. Tenant shall submit to the
Designer all additional information including occupancy requirements for
the Premises ("Information") necessary to enable the Designer to prepare a
space plan showing all demising walls, corridors, entrances, exits, doors,
interior partitions, and the locations of all offices, conference rooms,

Lease which Tenant is required to utilize in the construction of Tenant's
Work.

          Tenant shall cause the Designer to submit to Landlord the Space 
Plan for Landlord's review and approval. Landlord's approval of such 
Space Plan shall not be unreasonably withheld or delayed by Landlord, and 
shall be deemed given unless Landlord shall disapprove the same by written 
notice to Tenant within five (5) business days after Landlord's receipt of 
the same. Landlord's disapproval shall be based only upon reasonable and 
material reasons (which are defined to be (i) adverse effect on the 
structural integrity of the Building; (ii) possible damage to the Building 
Systems; (iii) non-compliance with applicable codes and other Laws; (iv) 
adverse effect on the exterior appearance of the Building; or (v) 
incompatibility with the Project including its design standards and standard 
materials (each, a "Design Problem")) and upon disapproval Landlord shall 
return the revised Space Plan to Tenant. In such event, Landlord shall 
require, and Tenant shall make, the changes necessary in order to correct the 
Design Problems and shall return the revised Space Plan to Landlord, which 
Landlord shall approve or disapprove within five (5) business days after

consistent with the Approved Space Plan, and shall be deemed given unless 
Landlord shall disapprove the same by written notice to Tenant given within 
five (5) business days after Landlord's receipt of a complete set of the 
Working Drawings. Landlord's disapproval shall be based only upon Design 
Problems(s) disclosed by such Working Drawings. If Landlord disapproves such 
Working Drawings in the manner and within the time provided in this Paragraph 
3(d), Landlord's notice of disapproval shall designate the specific changes 
reasonably required to be made to the Working Drawings in order to correct 
any Design Problem. Tenant shall make the changes necessary in order to 
correct any such Design Problem and shall return the revised Working Drawings 
to Landlord, which Landlord shall approve or disapprove within five (5) 
business days after Landlord receives the revised Working Drawings. This 
procedure shall be repeated until all of the Working Drawings are finally 
approved by Landlord and written approval has been delivered to and received 
by Tenant. The Working Drawings as finally approved pursuant to this 
Paragraph 3(d) are herein referred to as the "Approved Working Drawings."

          (e) PREPARATION AND APPROVAL OF ENGINEERING DRAWINGS. After the 
Working Drawings are finally approved by Landlord, Tenant shall submit to 
Landlord for Landlord's review and approval engineering drawings prepared by 
the Engineer, showing complete mechanical, electrical, plumbing, HVAC, 
telecommunication, and computer cabling plans ("Engineering Drawings"). The 
Engineering Drawings may be submitted in one or more stages and at one or 
more times.

          Landlord shall approve the Engineering Drawings within five (5) 
business days after receipt of a complete set of the same or designate by 
notice given within such time period to Tenant the specific changes 
reasonably required to be made to the Engineering Drawings in order to 
correct any Design Problem, and shall return the Engineering Drawings to 
Tenant. Tenant shall make the minimum changes necessary in order to correct 
any such Design Problem and shall return the revised Engineering Drawings to 
Landlord, which Landlord shall approve or disapprove within five (5) business 
days after Landlord receives the revised Engineering Drawings. This procedure 
shall be repeated until the Engineering Drawings are finally approved by 
Landlord and written approval has been delivered to and received by Tenant. 
The Engineering Drawings as finally approved pursuant to this Paragraph 3(e) 
are herein referred to as the "Approved Engineering Drawings."

          (f) INTEGRATION OF APPROVED WORKING DRAWINGS AND APPROVED 
ENGINEERING DRAWINGS INTO FINAL PLANS. Promptly after Landlord has approved 
the Approved Engineering Drawings, Tenant shall cause the Designer to 
integrate the Approved Working Drawings with the Approved Engineering 
Drawings (collectively, "Final Plans") and deliver the Final Plans to 
Landlord. Landlord shall approve the Final Plans within three (3) business 
days after receipt of a complete set of the same or designate by notice given

Landlord shall cooperate as reasonably requested from time to time without 
requirement that Landlord incur any out of pocket costs or assume any 
liabilities as a part of such cooperation.

after the execution of the Lease, such consent shall in no way operate as a
waiver or release of any of the provisions hereof or of the Lease, and

way. Tenant shall not throw anything out of doors, windows or skylights or 
down the passageways.

    10. No Tenant, or subtenant or assignee of Tenant, if any, nor any of 
their servants, employees, agents, visitors or licensees shall at any time 
bring or keep upon any premises any inflammable, combustible or explosive 
fluid, chemical or substance.

    11. No additional locks or bolts of any kind shall be placed upon any of 
the doors or windows by Tenant, nor shall any changes be made in existing 
locks or the mechanisms thereof. Tenant must, upon the termination of its 
tenancy, restore to Landlord all keys to stores, offices, and toilet rooms, 
either furnished to or otherwise procured by Tenant, and in the event of the 
loss of keys so furnished, Tenant shall pay to Landlord the cost of replacing 
the same or of changing the lock or locks opened by any lost key if Landlord 
shall deem it necessary to make such changes.

    12. All removals, and the carrying in or out of any safes, freight,

other fixtures and bulky matter of any kind must be done upon previous notice 
to the manager of the Building and under such person's supervision, and the 
persons employed by Tenant for such work must be acceptable to Landlord. 
Landlord reserves the right to inspect all safes, freight and other bulky 
articles to be brought into the Building and to exclude from the Building all 
safes, freight and other bulky articles which violated any of these Rules and 
Regulations or the Lease. Landlord reserves the right to prescribe the weight 
and position of all safes, which must be placed upon supports approved by 
Landlord to distribute the weight. No tenant shall place a load upon any 
floor which exceeds the load per square foot which such floor was designed to 
carry and which is allowed by law. Tenant shall be responsible for all 
damages occasioned by its movement into or out of the Building of any item 
described in this paragraph. All safes, freight and other bulky articles

or the Project or the desirability of the Project as an office location. 
Upon written notice from Landlord, Tenant shall refrain from or discontinue 
such advertising.

     15. Landlord reserves the right to exclude from the Building from 6:00

personnel and who do not present a pass to the Building approved by Landlord. 
Landlord will furnish passes to persons for whom Tenant requests the same in 
writing. Tenant shall be responsible for all persons for whom it requests 
passes and shall be liable to Landlord for all acts of such persons. Landlord 
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 an 
invasion, mob riot, public excitement or other circumstances rendering such 
action advisable in Landlord's opinion, Landlord reserves the right without 
any abatement of rent to require all persons to vacate the Building and to 
prevent access to the Building during the continuance of the same for the 
safety of Tenant and the protection of the Building and the property in the 
Building, and no such action by Landlord shall entitle Tenant to any 
abatement of rent. Tenant shall observe all security regulations issued by 
Landlord and shall comply with all instructions and/or directions of Building 
personnel.

     25. If Tenant desires fiber optic, telephone or telegraph connections, 
Landlord will direct electricians as to where and how the wires are to be 
introduced. No boring or cutting for wires or otherwise shall be made without 
directions from Landlord.

     26. The term "personal goods or services vendors" as used herein means
persons who periodically enter the Building for the purpose of selling

by Tenant only for the purpose of conducting its business on the Premises.
"Personal goods or services" include, but are not limited to, food items,
drinking water and other beverages, food, barbering services and
shoeshining services. Landlord reserves the right to prohibit personal
goods and services vendors from access to the Building except upon such
reasonable terms and conditions, including but not limited to the payment
of a reasonable fee and provision for insurance coverage, as are related to
the safety, care and cleanliness of the Building, the preservation of good
order therein, and the relief of any financial or other burden on Landlord
occasioned by the presence of such vendors or the sale by them of personal
goods or services to Tenant or its employees. If necessary for the
accomplishment of these purposes, Landlord may exclude a particular vendor
entirely or limit the number of vendors who may be present at any one time
in the Building.

employees with keys to its premises. Landlord will under no circumstances

     28. Smoking or carrying a lighted cigar, cigarette or pipe anywhere in 
the interior of the Building is prohibited. Smoking is also prohibited in the 
common areas of the Project, except for those specific areas designated in 
writing by Landlord. The location of such areas shall be determined by 
Landlord in its sole discretion. Landlord hereby reserves the right from time 
to time to designate substitute smoking areas within the common areas in its 
sole discretion. 

     29. No waiver of any rule or regulation by Landlord shall be effective 
unless expressed in writing and signed by Landlord. Landlord may waive any 
one or more of these rules for the benefit of a particular tenant or tenants, 
but no such waiver by Landlord shall be construed as a waiver of such rules 
in favor of any other tenant or tenants, nor prevent Landlord from thereafter 
enforcing any such rules against any or all tenants of the Building.

                                PARKING AGREEMENT    

   Subject to the parking entitlements, if any, set forth in the lease to 
which this Parking Agreement is attached (the "Lease") and subject to 
availability, and further subject to compliance with the following Rules and 
Regulations, so long as the Lease remains in effect and subject to 
availability, Tenant or employees of Tenant shall be entitled to purchase up 
to thirty-four (34) parking contracts for spaces in the Project Parking 
Structure in an amount as determined by Landlord. The Project Parking 
Structure is depicted on Exhibit "A-3." All or part of any unreserved or 
unassigned parking spaces may be assigned to, made available to, or reserved 
by Landlord for other tenants or users of the Project, if Landlord determines 
that such action is necessary for orderly and efficient parking. Tenant shall 
pay a charge for the use of such parking contracts at the monthly rental 
rates of $100.00 for reserved parking contracts and $60.00 per month for 
unreserved parking contracts. Tenant may validate visitor parking by such 
method(s) as Landlord or Landlord's parking operator may approve, at the 
validation rate from time to time generally applicable to visitor parking. 
Landlord expressly reserves the right to redesignate or modify any portion of 
the Project Parking Structure for other uses or to any extent.

   The parking spaces hereunder shall be provided on an unreserved 
"first-come, first-served" basis. Tenant acknowledges that Landlord has or 
may arrange for the Project Parking Structure to be operated by an 
independent contractor, not affiliated with Landlord. In such event, Tenant 
acknowledges that Landlord shall have no liability for claims arising through 
acts or omissions of such independent contractor. Landlord shall have no 
liability whatsoever for any damage to property or any other items located in 
the Project Parking Structure, nor for any personal injuries or death arising 
out of any matter relating to the Project Parking Structure, and in all 
events, Tenant agrees to look first to its insurance carrier and to require 
that Tenant's employees look to their respective insurance carriers for 
payment of any losses sustained in connection with any use of the Project 
Parking Structure. Tenant hereby waives on behalf of its insurance carriers 
all rights of subrogation against Landlord or Landlord's agents.

   All persons utilizing the Project Parking Structure shall comply with this 
Parking Agreement, including any parker identification system(s) established 
by Landlord's parking operator. The following Rules and Regulations are in 
effect until Landlord notifies Tenant of any change. Landlord reserves the 
right to modify and/or adopt such other reasonable and non-discriminatory 
rules and regulations for the Project Parking Structure as it deems 
necessary. Landlord may refuse to permit any person who violates this Parking 
Agreement to park in the Project Parking Structure. Any violation of this 
Parking Agreement shall subject the violator's car to removal from the 
Project Parking Structure at the violator's expense. Upon the termination of 
any person's parking privileges under this Parking Agreement, Tenant shall 
cause all parker identification devices supplied to such person by Landlord 
to be returned to Landlord.

mutilated in any manner. The serial number of the parking identification
device may not be obliterated. Devices are not transferable and any device
in the possession of an unauthorized holder will be void. There will be a
replacement charge payable by Tenant or a person designated by Tenant equal
to the amount posted from time to time by Landlord for loss of any parking
sticker.

   7. The monthly charge for rental of a parking space shall be payable in
advance on or prior to the first day of each month. Failure to do so will
automatically cancel parking privileges and a late charge at the rate
charged by Landlord from time to time shall be due. No deductions or
allowances from the monthly charge will be made for days a parker does not
use the parking space rented by him or her.

   8. Landlord's parking operator and its employees are not authorized to make
or allow any exceptions to these Rules and Regulations.

   9. Every parker is required to park and lock his or her own car. All
responsibility for damage to cars or persons is assumed by the parker.

   10. Loss or theft of parking identification devices from automobiles shall
be reported to the Landlord's parking operator immediately, and a lost or
stolen report must be filed by the customer at that time. Any parking
identification device reported lost or stolen found on any unauthorized car
will be confiscated and the illegal holder will be subject to prosecution.
Lost or stolen devices found by a parker must be reported to Landlord's
parking operator immediately to avoid confusion.

   11. No more than one vehicle may be parked in any one parking space.
Washing, waxing, cleaning or servicing of any vehicle by a parker and/or
his or her agents is prohibited.

   12. Landlord and Landlord's parking operator reserve the right to refuse
the sale of monthly stickers or other parking identification devices to
any person who willfully refuses to comply with these Rules and Regulations
and all applicable city, state or federal ordinances, laws or agreements.

   13. Tenant shall acquaint all persons to whom Tenant assigns parking spaces
with these Rules and Regulations.

   14. Notwithstanding anything in this Parking Agreement to the contrary,
persons who desire to rent parking spaces in the Project Parking Structure
shall be required to pay a $25.00 deposit for each magnetic parking card
issued to them by Landlord. Such deposit shall be paid at the time the
parking card is issued. Such deposit shall be forfeited if the parking
card is lost. Such deposit shall be returned, without interest, at the
time each such person ceases utilizing the parking space provided by
Landlord upon surrender of such person's parking card. Landlord reserves
the right to charge an amount in excess of the $25.00 deposit to replace
lost parking cards, if such increase becomes necessary in Landlord's
reasonable judgment to prevent creation of a so-called "black market" in
parking cards. Landlord shall post notices of any such increase(s).

   15. Handicapped and visitor stalls shall be used only by handicapped 
persons or visitors, as applicable.

   16. In the event that, from time to time, the Project Parking Structure is
renovated or replaced, in whole or in part, Landlord shall have the right
to reasonably relocate Tenant's parking privileges to other parking
facilities within the vicinity of the Project on a temporary basis.

   17. Parking on any driveways, access roads, turn-arounds and curbsides
