<PAGE>

                                 LEASE AGREEMENT

     THIS LEASE AGREEMENT is made and entered into this 21st day of April, 1995,
by and between CARIBBEAN/GENEVA INVESTORS, a California partnership, (herein
called, "Landlord"), and MACROVISION CORPORATION, a CALIFORNIA CORPORATION
(herein called "Tenant").

     Upon and subject to the terms, convenants and conditions hereinafter set
forth, Landlord hereby leases to Tenant and Tenant hereby hires from Landlord
those premises (the "Premises") comprising the area substantially as outlined in
red on attached EXHIBIT "A", in the building (hereinafter referred to as the
"Building") specified in the Basic Lease Information attached hereto. The
Building, together with the associated land, park, etc., may be more broadly
referred to as "Project."

     1.   OCCUPANCY AND USE.     Tenant shall use and occupy the Premises for
the purpose specified in the Basic Lease Information and for no other use or
purpose without the prior written consent of Landlord. Landlord shall have the
right to grant or withhold consent to a proposed change of use in its sole
discretion.

     2.   TERMS AND POSSESSION.

          (a)     The term of this Lease (the "Term") shall be for the period
specified in the Basic Lease Information (or until sooner terminated as herein
provided). If Landlord, for any reason whatsoever, cannot deliver possession of
the Premises to Tenant on the date specified in the Basic Lease Information for
the commencement of the Term, this Lease shall not be void or voidable, nor
shall Landlord be liable to Tenant for any loss or damage resulting therefrom.
In that event, however, Tenant shall not be liable for any Rent or Additional
Charges (as hereinafter defined) until Landlord delivers possession of the
Premises to Tenant. If Landlord tenders possession of the Premises to Tenant
prior to the commencement of the Term, then the Term and Tenant's obligations
hereunder shall commence on the date that it accepts such possession. If
substantial completion of the Premises is delayed beyond the scheduled
commencement of the Term for any reason other than a delay of Tenant or its
agents, representatives or contractors, the Term, scheduled commencement date
and scheduled expiration date shall be extended by the amount of such delay.
Notwithstanding the above, in the event that substantial completion is delayed
beyond June 30, 1995, then Tenant shall not be obligated to accept the Premises
(and have the Term commence) until August 1, 1995. In the event that the delay
in substantial completion beyond June 30, 1995 is related to the existing
tenant, Lockheed, holding over in the Premises after April 30, 1995 and Tenant
elects to accept the Premises prior to August 1, 1995, then Landlord shall
credit toward Tenant's rent an amount equal to one day's rent and holdover
penalties paid by Lockheed for the Premises during May of 1995 (estimated at
$1,482 per day) for each day during July of 1995 for which Tenant is paying rent
in both the Premises and its current premises at 700 El Camino Real East in
Mountain View. Notwithstanding the above, in the event that substantial
completion of the Premises has not occurred on or before September 30, 1995,
then Tenant shall have the right to terminate this lease by providing written
notice to Landlord of its decision to terminate the lease no later than October
15, 1995. The preceding three provisions shall be subject to Force Majeure
delays (as defined below) and Tenant delays, including, but not limited to,
changes in the plans for Tenant's improvements. Force Majeure Delays shall mean
and refer to a period of delay or delays encountered by Landlord because of:
fire, earthquake, flooding or other acts of God; acts of the public enemy, riot,
or insurrection; governmental regulations enacted after this Lease is executed
and beyond the control of Landlord; strikes or boycotts, shortages of unique
materials or any other industry or area-wide cause beyond the control of
Landlord. The dates upon which the Term shall commence and terminate pursuant to
this Paragraph 2(a) are herein called the "Commencement Date" and the
"Expiration Date," respectively.

          (b)     Completion of the improvements to the Premises shall be
governed by the terms and conditions of the separate work letter ("Work
Letter"), attached hereto as EXHIBIT "B".

          (c)     The Premises shall be deemed completed and possession
delivered when Landlord has substantially completed the work to be constructed
or installed by Landlord ("Landlord's Work") pursuant to the provisions of the
Work Letter subject only to the completion of items on Landlord's architect's
punch list (and exclusive of the installation of all telephone and other
communications facilities and equipment and other finish work or decorating work
to be performed by or for Tenant). Tenant shall accept the Premises upon notice
from Landlord that Landlord's Work has been so substantially completed (and
provided that Tenant has had a reasonable opportunity to verify the same) and
Tenant's obligation to pay rent hereunder shall commence on the earlier to
occur of: (i) the date on which Landlord's Work is substantially completed; or 
(ii) the date on which Tenant takes possession of, or commences the operation 
of its business in, any or all of the Premises. However, in no event shall 
Tenant be required to accept the Premises prior to July 1, 1995. By occupying 
the Premises, Tenant shall be deemed to have accepted the same as suitable for 
the purpose herein intended and to have acknowledged that the same comply fully
with Landlord's obligations, notwithstanding that certain "punch list" type 
items may not have been completed. However, acceptance of the space by, Tenant 
shall not relieve Landlord of its obligation to complete outstanding punch-list
items which are Landlord's responsibility. Within five (5) days after written 
request of Landlord, Tenant agrees to


                            Lease Agreement - Page 1

<PAGE>

give Landlord a letter confirming the Commencement Date and certifying that
Tenant has accepted delivery of the Premises (latent defects expected) and that
the condition of the Premises complies with Landlord's obligations hereunder, or
in the event the condition of the Premises does not comply, stating how it does
not comply. The Premises shall be substantially completed when (i) Tenant has
safe and direct access to the Premises from the sidewalk and parking area
adjacent to the Building, (ii) the work to be completed by Landlord, pursuant to
the Work Letter, is completed subject only to completion of items on Landlord's
Architect's punch list, which do not materially interfere with Tenant's use of
the Premises, and (iii) a Certificate of Occupancy or its equivalent has been
issued by the City or other applicable governmental agency for the Premises.
Landlord shall use its best efforts to advise Tenant of the anticipated date of
completion at least fifteen (15) days prior to such date, but the failure to
give such notice shall not constitute a default hereunder by Landlord.
Notwithstanding the above, at no cost to Tenant, in the event that substantial
completion of the Premises occurs prior to June 26, 1996, Landlord shall provide
Tenant with access to the space one (1) week prior to the commencement date to
install partition systems, install phone and data cabling and otherwise set up
the office. However, as much as is possible, Tenant's cabling contractors will 
work with Landlord's contractor to install cabling prior to this period if 
requested by Landlord.

          (d)     Tenant shall, no later than thirty (30) days after the date of
issuance by the appropriate governmental agency of a Certificate of Occupancy or
its equivalent concerning the Improvements, go into actual physical occupancy of
the Premises and open the Premises for business in accordance with the uses
specified in Paragraph 4 below. Time is of essence. In the event Tenant fails to
perform its obligations pursuant to this Section 2(d), Tenant shall indemnify
and hold Landlord harmless from any loss or liability arising from Tenant's
failure to occupy the Premises and open the Premises for business.

     3.   RENT; RENT ADJUSTMENTS; ADDITIONAL CHARGES FOR EXPENSES AND TAXES.

          (a)     MONTHLY BASE RENT.     Tenant shall pay to Landlord 
throughout the Term the annual rental specified in the Basic Lease 
Information ("Rent"), which sum shall be payable by Tenant in equal monthly 
installments on or before the first day of each month, in advance, with the 
first month's rent due upon execution of this Lease Agreement, in lawful 
money of the United States, without any prior demand therefor and without 
deduction or offset whatsoever, to Landlord or its managing agent at the 
address specified in the Basic Lease Information or to such other firm or to 
such other place as Landlord or its Managing Agent may from time to time 
designate in writing. Tenant shall pay to Landlord all charges and other 
amounts whatsoever as provided in this Lease ("Additional Charges") at the 
place where the Rent is payable and Landlord shall have the same remedies for 
a default in the payment of Additional Charges as for a default in the 
payment of Rent. If the Commencement Date should occur on a day other than 
the first day of a calendar month, or the Expiration Date should occur on a 
day other than first day of a calendar month, or the Expiration Date should 
occur on a day other than the last day of a calendar month, then the Rent and 
Additional Charges for such fractional month shall be prorated on a daily 
basis.

          (b)     ADJUSTMENTS IN RENT.     The monthly base rent under Paragraph
3(a) shall be adjusted at the beginning of months 37 and 73 of the Term reflect
any increase in the cost of living. The amount of such increase in the monthly
base rent, if any, shall be determined by multiplying $29,892.80 by a fraction,
the denominator of which shall be the most recent Consumer Price Index (as
hereinafter defined) figure published prior to the Commencement Date, and the
numerator of which shall be the most recent Consumer Price Index figure
published prior to the date of such adjustment; provided, however, in no event
shall the increase in Rent over the Rent in place immediately before the
increase be less than ten percent (10%) nor greater than fifteen percent (15%).
As used herein, the term "Consumer Price Index" shall mean the United States
Department of Labor, Bureau of Labor Statistics, Consumer Price Index, All
Urban Consumers, All Items, San Francisco-Oakland, California (1982-84 equals
100). If, during the Term, the aforesaid Index is no longer published, 
Landlord shall, for the purposes of computation of any adjustments in Rent, 
substitute such other Index as is then generally recognized as most 
comparable to the aforementioned Index and accepted for similar 
determinations. Should Landlord lack sufficient data to make the 
determination specified in this Paragraph 3(b) on the date of any such 
adjustment, Tenant shall continue to pay the monthly Rent payable immediately 
prior to such adjustment date. As soon as Landlord obtains the necessary 
data, it shall determine the Rent payable from and after such adjustment date 
and notify Tenant of the adjustment in writing. If the monthly Rent for the 
period following such adjustment date exceeds the amount previously paid by 
Tenant for such period, Tenant shall forthwith pay the difference to Landlord.

          (c)     ADDITIONAL CHARGES FOR EXPENSES AND TAXES.

          (1)     For purposes of this Paragraph 3(c), the following terms shall
have the meanings hereinafter set forth:

                      (A) "Tax Year" shall mean each twelve (12) consecutive 
     month period commencing January 1st of the calendar year during which the
     Commencement Date of this Lease occurs, provided that Landlord, upon notice
     to Tenant, may change the Tax Year from time to time to any other twelve
     (12) consecutive month period and, in the event of any such change,
     Tenant's Share of


                            Lease Agreement - Page 2

<PAGE>

     Real Estate Taxes (as hereinafter defined) shall be equitably adjusted for
     the Tax Years involved in any such change.

                      (B) "Tenant's Share" shall mean the percentage figure so
     specified in the Basic Lease Information.

                      (C) "Real Estate Taxes" shall mean all taxes, assessments 
     and charges levied upon or with respect to the Project or any personal 
     property of Landlord used in the operation of thereof, or Landlord's 
     interest in the Project or such personal property. Real Estate Taxes shall 
     include, without limitation, all general real property taxes and general 
     and special assessments, charges, fees or assessments for transit, housing,
     police, fire or other governmental services or purported benefits to the 
     Building, service payments in lieu of taxes, and any tax, fee or excise on 
     the act of entering into this Lease, or any other lease of space in the 
     Building, or on the use or occupancy of the Building or any part thereof, 
     or on the rent payable under any lease or in connection with the business 
     of renting space in the Building, that are now or hereafter levied or 
     assessed against Landlord by the United States of America, the State 
     of California, or any political subdivision, public corporation, district 
     or any other political or public entity, and shall also include any other 
     tax, fee or other excise, however described, that may be levied or assessed
     as a substitute for, or as an addition to, in whole or in part, any other 
     Real Estate Taxes, whether or not now customary or in the contemplation 
     of the parties on the date of this Lease. Real Estate Taxes shall not 
     include franchise, transfer, inheritance or capital stock taxes or  
     income taxes measured by the net income of Landlord from all sources 
     unless, due to a change in the method of taxation, any of such taxes is 
     levied or assessed against Landlord as a substitute for, or as an 
     addition to, in whole or in part, any other tax that would otherwise  
     constitute a Real Estate Tax. Real Estate Taxes shall also include 
     reasonable legal fees, costs and disbursements incurred in connection 
     with proceedings to contest, determine or reduce Real Estate Taxes (such 
     proceedings to be those from which a reasonable person would anticipate 
     that savings would actually result and with which Tenant reasonably 
     agrees). Notwithstanding anything to the contrary set forth above, 
     Tenant shall not be responsible for increases in Real Estate Taxes which 
     are related to an increase in the assessed value of the property in 
     excess of the "Agreed Upon Assessed Value." The Agreed Upon Assessed 
     Value shall be $4,567,000 for the period from July 1, 1994 through June 30,
     1995, and shall increase at a rate of five percent (5%) during each 
     succeeding twelve (12) month period.

                      (D) "Expenses" shall mean the total direct costs 
     and reasonable expenses paid or incurred by Landlord in connection with 
     the management, operation, maintenance and repair of the Building, 
     including, without limitation (i) the cost of air conditioning, 
     electricity, steam, heating, mechanical, ventilating, elevator systems 
     and all other utilities and the cost of supplies and equipment and 
     maintenance and service contracts in connection therewith; (ii) the cost 
     of repairs and general maintenance and cleaning; (iii) the cost of fire, 
     extended coverage, boiler, sprinkler, public liability, property damage, 
     rent, earthquake (if available at commercially reasonable rates) and 
     other insurance; (iv) fees, charges and other costs, including 
     management fees, consulting fees, legal fees (which are allowed 
     elsewhere in the Lease) and accounting fees, of all independent 
     contractors engaged by Landlord directly related to the operation of the 
     Building or reasonably charged by Landlord if Landlord performs 
     management services in connection with the Building; (v) the cost of any 
     membership fees, expenses or charges imposed by any owner's or tenant's 
     association created to manage and/or maintain the common areas or public 
     areas of the Project in which the Building is located and the Building's 
     Share of all costs of such common or public area management and 
     maintenance; (vi) the cost of any capital improvements made to the 
     Building after completion of its construction as a labor saving device or 
     to effect other economies in the operation or maintenance of the Building 
     (from which a reasonable person would anticipate that savings would 
     actually result and with which Tenant agrees), or that are made to the 
     Building after the date of this Lease and are required under any 
     governmental law or regulation that was not applicable to the Building 
     at the time that permits for the construction thereof of Tenant's 
     improvements were obtained, such cost to be amortized over such 
     reasonable period as defined under generally accepted accounting 
     principles ("GAAP"), together with interest on the unamortized balance at 
     the rate of ten percent (10%) per annum or such higher rate as may have 
     been paid by Landlord on funds borrowed for the purpose of constructing 
     such capital improvements; and (viii) any other reasonable expenses of 
     any other kind whatsoever reasonably incurred in managing, operating, 
     maintaining and repairing the Building.
     
     Notwithstanding anything to the contrary herein contained, Expenses 
     shall not include (aa) the initial construction cost of the Project or 
     real property on which the Building is located; (bb) the cost of 
     providing tenant improvements to Tenant or any other tenant; (cc) debt 
     service (including, but without limitation, interest, principal and any 
     impound payments) required to be made on any mortgage or deed of trust 
     recorded with respect to the Building and/or the real property on which 
     the Building is located other than debt service and financing charges 
     imposed pursuant to Paragraph 3(c)(1)(D)(vi) above; (dd) the cost of 
     special services, goods or materials provided to any tenant, (ff) the 
     portion of a management fee paid to Landlord or affiliate in excess of 
     two percent (2%) of Rent and Additional Charges; costs to maintain the 
     Building's foundations, exterior walls, and structural roof. In no event 
     shall Landlord be entitled to collect in excess of one hundred percent
     
                            Lease Agreement - Page 3
                         
<PAGE>
     (100%) of the total Expenses from all of the tenants in the Building 
     including Tenant. All costs and expenses shall be determined  in 
     accordance with generally accepted accounting principles which shall be 
     consistently applied (with accruals appropriate to Landlord's business). 
     Expenses shall not include specific costs incurred for the account of, 
     separately billed to and paid by specific tenants.
     
               (E) "Expense Year" shall mean each twelve (12) consecutive 
     month period commencing January 1 of the calendar year during which the 
     Commencement Date of the Lease occurs, provided that Landlord, upon 
     notice to Tenant, may change the Expense Year from time to time to any 
     other twelve (12) consecutive month period, and, in the event of any 
     such change, Tenant's Share of Expenses shall be equitably adjusted for 
     the Expense Years involved in any such change.

          (2) Tenant shall pay to Landlord as Additional Charges one-twelfth 
(1/12th) of Tenant's Share of Real Estate Taxes for each Tax Year on or 
before the first day of each month during such Tax Year, in advance, in an 
amount reasonably estimated by Landlord and billed by Landlord to Tenant, and 
Landlord shall have the right initially to determine monthly estimates and to 
revise such estimates from time to time. With reasonable promptness after 
Landlord has received the tax bills for any Tax Year, Landlord shall furnish 
Tenant with a statement (herein called "Landlord's Tax Statement") setting 
forth the amount of Real Estate Taxes for such Tax Year, and Tenant's Share 
thereof. If the actual Real Estate Taxes for such Tax Year exceed the 
estimated Real Estate Taxes paid by Tenant for such Tax Year, Tenant shall 
pay to Landlord the difference between the amount paid by Tenant and the 
actual Real Estate Taxes within fifteen (15) days after the receipt of 
Landlord's Tax Statement, and if the total amount paid by Tenant for any such 
Tax Year shall exceed the actual Real Estate Taxes for such Tax Year, such 
excess shall be credited against the next installment of Real Estate Taxes 
due from Tenant to Landlord hereunder.

          (3) Tenant shall pay to Landlord as Additional Charges one-twelfth 
(1/12th) of Tenant's Share of the Expenses for each Expense Year on or before 
the first day of each month of such Expense Year, in advance, in an amount 
reasonably estimated by Landlord and billed by Landlord to Tenant, and 
Landlord shall have the right initially to determine monthly estimates and to 
revise such estimates from time to time. With reasonable promptness after the 
expiration of each Expense Year, Landlord shall furnish Tenant with a 
statement (herein called "Landlord's Expense Statement"), setting forth in 
reasonable detail the Expenses for such Expense Year and Tenant's Share 
thereof. If the actual Expenses for such Expense Year exceed the estimated 
Expenses paid by Tenant for such Expense Year, Tenant shall pay to Landlord 
the difference between the amount paid by Tenant and the actual Expenses 
within fifteen (15) days after the receipt of Landlord's Expense Statement, 
and if the total amount paid by Tenant for any such Expense Year shall exceed 
the actual Expenses for such Expense Year, such excess shall be credited 
against the next installment of the estimated Expenses due from Tenant to 
Landlord hereunder returned to Tenant within thirty (30) days, unless Tenant 
is delinquent on its rent.

          (4) To the extent any item of Real Estate Taxes or Expenses is 
payable by Landlord in advance of the period to which it is applicable (e.g. 
insurance), Landlord may (i) include Tenant's share of such items in 
Landlord's estimate for periods prior to the date such item is payable by 
Landlord and (ii) to the extent Landlord has not collected the full amount of 
such item prior to the date such item is payable by Landlord, Landlord may 
include Tenant's Share of the balance of such full amount in a revised 
monthly estimate for additional charges. If the Commencement Date or 
Expiration Date shall occur on a date other than the first day of a Tax Year 
and/or Expense Year, Tenant's share of Real Estate Taxes and Expenses, for 
the Tax Year and/or Expense Year in which the Commencement Date occurs shall 
be prorated.

          (5) Within ninety (90) days after receipt of any Expense Statement 
or Tax Statement from Landlord, Tenant shall have the right to examine 
Landlord's books and records relating to such Expense Statements and Tax 
Statements, or cause an independent audit thereof to be conducted by an 
accounting firm to be selected by Tenant and subject to the reasonable 
approval of Landlord.

          (d) LATE CHARGES. Tenant recognizes that late payment of any Rent or 
Additional Charges will result in administrative expenses to Landlord, the 
extent of which additional expense is extremely difficult and economically 
impractical to ascertain. Tenant therefore agrees that if any Rent or 
Additional Charges remain unpaid ten (10) days after the amount is due and 
written notice has been given, the amount of such unpaid Rent or Additional 
Charges shall be increased by a late charge to be paid to Landlord by Tenant 
in an amount equal to four percent (4%) of the amount of the delinquent Rent 
or Additional Charges. After the initial late charge is imposed for Rent, 
Additional Charges and other outstanding amounts for any specific month, late 
charges on the Rent, Additional Charges and other outstanding amounts for 
that specific month shall accrue interest during future months at an 
annualized rate of Prime rate (as set by the Bank of America) plus five 
percent (5%) until paid to Landlord. Tenant agrees that such amount is a 
reasonable estimate of the loss and expense to be suffered by Landlord as a 
result of such late payment by Tenant and may be charged by Landlord to 
defray such loss and expense. The provisions of this Paragraph 3(d) in no way 
relieve Tenant of the obligation to pay Rent or Additional Charges on or 
before the date on which they 


                             Lease Agreement - Page 4
<PAGE>
are due, nor do the terms of this Paragraph 3(d) in any way affect Landlord's 
remedies pursuant to Paragraph 19 in the event any Rent or Additional Charges 
are unpaid after the date due.

     4. RESTRICTIONS ON USE. Tenant shall not do or permit anything to be 
done in or about the Premises which will obstruct or interfere with the 
rights of other tenants or occupants of the Building or the Project or injure 
or annoy them, nor use or allow the Premises to be used for any improper, 
immoral, unlawful or objectionable purpose, nor shall Tenant cause or 
maintain or permit any nuisance in, on or about the Premises. Tenant shall 
not commit or suffer the commission of any waste in, on or about the Premises.

     5. COMPLIANCE WITH LAWS. Tenant shall not use the Premises or permit 
anything to be done in or about the Premises which will in any way conflict 
with any law, statute, ordinance or governmental rule or regulation, 
including all Environmental Laws as hereinafter defined in Paragraph 42, 
relating to the use of the Premises now in force or which may hereafter be 
enacted or promulgated. Tenant shall not do or permit anything to be done in 
or about the Premises or bring or keep anything therein which will in any way 
increase the rate of any insurance upon the Project (unless Tenant agrees to 
pay for such increases) or any of its contents or cause a cancellation of 
such insurance or otherwise affect such insurance in any manner, and Tenant 
shall at its sole cost and expense promptly comply with all laws, statutes, 
ordinances and governmental rules, regulations or requirements now in force 
or which may hereafter be in force including, without limitation, all 
Environmental Laws and with the requirements of any board of fire 
underwriters or other similar body now or hereafter constituted relating to 
or affecting the condition, use or occupancy of the Premises, excluding 
structural changes not related to or affected by Tenant's unique use of the 
Premises or alterations or improvements made by or for Tenant or Tenant's 
acts. The judgment of any court of competent jurisdiction or the admission of 
Tenant in an action against Tenant, whether Landlord be a party thereto or not,
that Tenant has so violated any such law, statute, ordinance, rule, 
regulation or requirement, shall be conclusive of such violation as between 
Landlord and Tenant.

     6. ADDITIONAL ALTERATIONS. After completion of the improvements 
described in or contemplated by the Work Letter, Tenant shall not make or 
suffer to be made any additional alterations, additions or improvements 
("Alterations") in, on or to the Premises or any part thereof without the 
prior written consent of Landlord (excepting painting, carpeting, 
wallcovering, light fixtures, electrical outlets, other communications ports 
and computer wiring, cabinets and bookshelves, and warehouse racks which are 
consistent with improvements and finishes previously approved by Landlord); 
and any Alterations in, on or to the Premises, except for Tenant's movable 
furniture and equipment (including equipment such as shelving, antennas, 
satellite dishes or other similar equipment typically bolted down for safety 
purposes), shall immediately become Landlord's property and, at the end of 
the Term, shall remain on the Premises without compensation to Tenant. 
Landlord shall not unreasonably withhold its consent to Alterations that (i) 
do not affect the structure of the Building or its electrical, plumbing, 
HVAC, security or other systems, (ii) are not visible from the exterior of 
the Premises, and (iii) are consistent with Tenant's permitted use hereunder. 
In the event Landlord consents to the making of any Alterations by Tenant, 
the same shall be made by Tenant, at Tenant's sole cost and expense, in 
accordance with plans and specifications reasonably approved by Landlord, and 
any contractor or person selected by Tenant to make the same must first be 
reasonably approved in writing by Landlord or, at Landlord's option, the 
Alterations shall be made by Landlord for Tenant's account and Tenant shall 
reimburse Landlord for the competitively bid cost thereof (including a 
reasonable charge for Landlord's overhead) within twenty (20) days after 
receipt of a statement from Landlord therefor. Upon the expiration or sooner 
termination of the Term, Tenant shall upon demand by Landlord, at Tenant's 
sole cost and expense, forthwith and with all due diligence remove any 
Alterations made by or for the account of Tenant, designated by Landlord to 
be removed (provided, however, that upon the written request of Tenant prior 
to installation of such Alterations, Landlord shall advise Tenant at that 
time whether or not such Alterations must be removed upon the expiration or 
sooner termination of this Lease), and Tenant shall forthwith and with all 
due diligence, at its sole cost and expense, repair and restore the Premises 
to its original condition, subject to normal wear and tear and the rights and 
obligations of Tenant concerning casualty damage pursuant to Paragraph 20.

     7. REPAIR AND MAINTENANCE.

          (a) Landlord shall be responsible for the following repair and 
maintenance obligations: (i) maintenance and repair of the exterior, roof and 
structural portions of the Building, (ii) repairs and maintenance of the 
Building systems for electrical, mechanical, HVAC or plumbing and all 
controls appurtenant thereto, and (iii) parking areas, courtyards, sidewalks, 
entry ways, lawns, landscaping and other similar facilities of the Project. 
In the event that Tenant desires to directly manage the maintenance of the 
mechanical and HVAC systems or the plumbing and all controls appurtenant 
thereto, then Landlord agrees to not unreasonably withhold its approval so 
long as Tenant adequately maintains such equipment, as 


                               Lease Agreement - Page 5
<PAGE>

reasonably determined by Landlord. Tenant shall have the authority to 
communicate directly with Landlord's roof maintenance company. In emergency 
situations, Tenant shall have the authority to contact directly any venders 
approved by Landlord and order repairs. In the event that Landlord fails to 
pursue its duties as noted above within thirty (30) days of written request 
from Tenant, excepting structural changes, then Tenant shall have the right 
to contact any venders approved by Landlord and directly contract for said 
repairs and maintenance provided that Tenant agrees to pay for the cost of 
said repairs and maintenance.

          (b) Tenant shall maintain and repair the interior portion of the 
Premises and any additional tenant improvements, alterations or additions 
installed by or on behalf of Tenant within the Premises, however, excluding 
any portions thereof which are structural in nature or which are a part of 
the electrical, mechanical, HVAC or plumbing systems of the Premises. Tenant 
shall be responsible for the expense of installation, operation, and 
maintenance of its telephone and other communications cabling from the point 
of entry into the Building to the Premises and throughout the Premises; 
though Landlord shall have the right to perform such work on behalf of Tenant 
in Building Common Areas. Tenant hereby waives and releases its right to make 
repairs at Landlord's expense under Sections 1941 and 1942 of the California 
Civil Code or under any similar law, statute or ordinance now or hereafter in 
effect. In addition, Tenant hereby waives and releases its right to terminate
this Lease under Section 1932(1) of the California Civil Code or under any 
similar law, statute or ordinance now or hereafter in effect. If Tenant fails 
after ten (10) days' written notice by Landlord to proceed with due diligence 
to make repairs required to be made by Tenant, the same may be made by 
Landlord at the expense of Tenant and the expenses thereof incurred by 
Landlord shall be reimbursed immediately as Additional Rent within thirty 
(30) days after submission of a bill or statement therefor.

          (c) The purpose of Section 7(a) and 7(b) is to define the 
obligations of Landlord and Tenant to perform various repair and maintenance 
functions; the allocation of the costs therefore are covered under this 
Section 7(c) and Section 3. Tenant shall bear the full cost of repairs or 
maintenance interior or exterior, excluding structural changes, to preserve 
the Premises and the Building in good working order and condition, arising 
out of (i) the performance or existence of any alteration or modification to 
the Premises made by Tenant; (ii) the installation, use or operation of 
Tenant's property or fixtures; (iii) the moving of Tenant's property or 
fixtures in or out of the Building or in and about the Premises; or (iv) the 
acts, omissions or negligence of Tenant or any person claiming or acting 
through or under Tenant, or any of its servants, employees, contractors, 
agents, visitors, or licensees, or the use or occupancy or manner of use or 
occupancy of the Premises by Tenant or any such person.

          (d) Except as provided in Paragraph 20, there shall be no abatement 
of Rent with respect to, and except for Landlord's gross negligence or 
willful misconduct, Landlord shall not be liable for any injury to or 
interference with Tenant's business arising from, any repairs, maintenance, 
alteration or improvement in or to any portion of the Building, including the 
Premises, or in or to the fixtures, appurtenances and equipment therein.

     8. LIENS. Tenant shall keep the Premises free from any liens arising out 
of any work performed, material furnished or obligations incurred by Tenant. 
In the event that Tenant shall not, within ten (10) days following the 
imposition of any such lien, cause the same to be released of record by 
payment or posting of a proper 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 the claim giving rise to such lien. All such sums paid 
by Landlord and all expenses incurred by it in connection therewith shall be 
considered Additional Charges and shall be payable to it by Tenant on demand 
with interest at the maximum rate permitted by law. Landlord shall have the 
right at all times to post and keep posted on the Premises any notices 
permitted or required by law, or which Landlord shall deem proper, for the 
protection of Landlord, the Premises, the Building and any other party 
having an interest therein, from mechanics' and materialsmen's liens, and 
Tenant shall give notice to Landlord at least five (5) business days' prior 
notice of commencement of any construction on the Premises.

     9. ASSIGNMENT AND SUBLETTING.

          (a) Tenant shall not directly or indirectly, voluntarily or by 
operation of law, sell, assign, encumber, pledge or otherwise transfer or 
hypothecate all or any part of the Premises or Tenant's leasehold estate 
hereunder (collectively, "Assignment"), or permit the Premises to be occupied 
by anyone other than the Tenant or sublet the Premises (collectively, 
"Sublease") or any portion thereof without Landlord's prior written consent 
in each instance, which consent shall not be unreasonably withheld by 
Landlord. Without otherwise limiting the criteria upon which Landlord may 
withhold its consent to any proposed Sublease or Assignment, if Landlord 
withholds its consent where either (i) the proposed Subleasee's or Assignee's 
net

worth (according to generally accepted accounting principles) is less than 
the net worth of Tenant at the time this Lease is executed, or (ii) the 
proposed Sublessee's or Assignee's use of the Premises is not in compliance 
with the allowed Tenant's Use of the Premises as described in the Basic Lease 
Information, such withholding of consent shall be presumptively reasonable. 
If Landlord consents to the Sublease or Assignment, Tenant may thereafter 
enter into a valid Sublease or Assignment upon the terms and condition set 
forth in this Section 9.

          (b) If Tenant desires at any time to enter into an Assignment of 
this Lease or a Sublease of the Premises or any portion thereof, it shall 
first give written notice to Landlord of its desire to do so, which notice 
shall contain (i) the name of the proposed assignee, subtenant or occupant; 
(ii) the name of the proposed assignee's, subtenant, or occupant's business 
to be carried on in the Premises; (iii) the terms and provisions of the 
proposed Assignment or Sublease; and (iv) such financial information as 
Landlord may request concerning the proposed assignee, subtenant or occupant.

          (c) At any time within fifteen (15) days after Landlord's receipt 
of the notice specified in Paragraph 9(b), Landlord shall by written notice 
to Tenant elect to (i) sublease itself the portion of the Premises specified 
in Tenant's notice of intended Sublease; (ii) take an Assignment of Tenant's 
leasehold estate specified in Tenant's notice hereunder; (iii) terminate this 
Lease as to the portion (including all) of the Premises that is specified in 
Tenant's notice of intended Assignment, with a proportionate abatement in 
Rent and Additional Charges; (iv) consent to the Sublease or Assignment; or 
(v) disapprove the Sublease or Assignment. In the event Landlord elects to 
Sublease or take an Assignment from Tenant as described in clauses (i) and 
(ii) above, the rent payable by Landlord shall be the lower of that set forth 
in Tenant's notice or the Rent payable by Tenant under this Lease at the time 
of the Assignment of Sublease (or a proportionate amount thereof representing 
the portion of the Premises subject to the Assignment or Sublease if less 
than the entire Premises is subject to the Assignment or Sublease). In the 
event Landlord elects any of the options set forth in clauses (i), (ii), or 
(iii) above, with respect to a portion of the Premises, Tenant shall at all 
times provide reasonable and appropriate access to such portion of the 
Premises and use of any common facilities, and Landlord shall have the right 
to use such portion of the Premises for any legal purpose in its sole 
discretion and the right to further assign or sublease the portion of the 
Premises subject to Landlord's election without the consent of Tenant. If 
Landlord consents to the Sublease or Assignment within said fifteen (15) day 
period, Tenant may thereafter within thirty (30) days after Landlord's 
consent, but not later than the expiration of said thirty (30) days, enter 
into such Assignment or Sublease of the Premises or portion thereof, upon the 
terms and conditions set forth in the notice furnished by Tenant to Landlord 
pursuant to Paragraph 9(b). Failure by Landlord to either consent or refuse 
such consent to a proposed assignment, encumbrance or sublease within the 
fifteen (15) day time period specified above shall be deemed to be Landlord's 
consent thereto.

          (d) No consent by Landlord to any Assignment or Sublease by Tenant 
shall relieve Tenant of any obligation to be performed by Tenant under this 
Lease, whether arising before or after the Assignment or Sublease. The 
consent by Landlord to any Assignment or Sublease shall not relieve Tenant 
from the obligation to obtain Landlord's express written consent to any other 
Assignment or Sublease. Any Assignment or Sublease that is not in compliance 
with this Paragraph 9 shall be void and, at the option of Landlord, shall 
constitute a material default by Tenant under this Lease. The acceptance of 
Rent or Additional Charges by Landlord from a proposed assignee or sublessee 
shall not constitute the consent to such Assignment or Sublease by Landlord.

          (e) The following shall be deemed a voluntary assignment of 
Tenant's interest in this Lease: (i) any dissolution, merger, consolidation, 
or other reorganization of Tenant; and (ii) if the capital stock of Tenant is 
not publicly traded, the sale or transfer to one person or entity stock 
possessing more than fifty percent (50%) of the total combined voting power 
of all classes of Tenant's capital stock issued, outstanding and entitled to 
vote for the election of directors. Notwithstanding anything to the contrary 
contained in this paragraph 9, Tenant may enter into any of the following 
transfers (a "Permitted Transfer") without Landlord's prior written consent:

               (1) Tenant may assign its interest in the Lease to a 
corporation which results from a merger, consolidation or other 
reorganization, so long as the surviving corporation has a net worth 
immediately following such transaction that is equal to or greater than the 
net worth of Tenant immediately prior to such transaction; and

               (2) Tenant may assign this Lease to a corporation which 
purchases or otherwise acquires all or substantially all of the assets of 
Tenant, so long as such acquiring corporation has a net worth immediately 
following such transaction that is equal to or greater than the net worth of 
Tenant immediately prior to such transaction.

          (f) Each assignee, sublessee or other transferee, other than 
Landlord, shall assume, as provided in this Paragraph 9(f), all obligations 
of Tenant under this Lease and shall be and remain liable jointly and 
severally with Tenant for the payment of Rent and Additional Charges, and for 
the performance of all the terms, covenants, conditions and agreements herein 
contained on Tenant's part to be performed for

                            Lease Agreement - Page 7

<PAGE>

the Term; provided, however, that the assignee, sublessee, mortgagee, pledgee 
or other transferee shall be liable to Landlord for rent only in the amount 
set forth in the Assignment or Sublease. No Assignment shall be binding on 
Landlord unless the assignee or Tenant shall deliver to Landlord a 
counterpart of the Assignment and an instrument in recordable form that 
contains a covenant of assumption by the assignee satisfactory in substance 
and form to Landlord, consistent with the requirements of this Paragraph 
9(f), but the failure or refusal of the assignee to execute such instrument 
of assumption shall not release or discharge the assignee from its liability 
as set forth above.

          (g) Landlord will approve within ten (10) days of receipt of 
written notice the assignment of Tenant's interest in the lease or sublease 
of the Premises by Tenant to an affiliate provided that (i) the affiliate 
delivers to the Landlord concurrent with such assignment a written notice of 
the assignment and an assumption agreement whereby the affiliate assumes to 
perform, observe and abide by the terms, conditions, obligations, and 
provisions of this lease, and (ii) the entity remains an affiliate. No 
subletting or assignment by Tenant made pursuant to this Section shall 
relieve Tenant of Tenant's obligations under this Lease. As used herein, the 
term "affiliate" shall mean and collectively refer to a corporation or other 
entity in which Tenant, (the "parent") owns directly or indirectly at least a 
51 percent ownership interest.

     10. INSURANCE AND INDEMNIFICATIONS.

          (a) Landlord shall indemnify and hold Tenant harmless from and 
against any and all claims or liability for any injury or damage to any 
person or property (but excluding any consequential damages or loss of 
business) occurring in, on, or about the Building to the extent such injury or 
damage is caused by the negligence or willful misconduct of Landlord, its 
agents, servants, or employees ("Landlord Parties").

          (b) Landlord shall not be liable to Tenant, and Tenant hereby 
waives all claims against Landlord Parties for any injury or damage to any 
person or property in or about the Premises by or from any cause whatsoever 
(other than the negligence or willful misconduct of Landlord Parties, 
including Landlord's negligence or willful misconduct as related to 
construction or property management), and without limiting the generality of 
the foregoing, whether caused by water leakage of any character from the 
roof, walls, basement, or other portion of the Premises or the Building, or 
caused by gas, fire, oil, electricity, or any cause whatsoever, in, on, or 
about the Premises, the Building or any part thereof (other than that caused 
by the negligence or willful misconduct of Landlord parties). Tenant 
acknowledges that any casualty insurance carried by Landlord will not cover 
loss of income to Tenant or damage to the alterations in the Premises 
installed by Tenant or Tenant's personal property located within the 
Premises. Tenant shall be required to maintain the insurance described in 
subparagraph (d) below during the Term.

          (c) Tenant shall indemnify and hold Landlord harmless from and 
defend Landlord against any and all claims or liability for any injury or 
damage to any person or property whatsoever: (i) occurring in, on, or about 
the Premises; or (ii) occurring in, on, or about any other portion of the 
Project when such injury or damage shall be caused in whole or in part by the 
negligence or willful misconduct by Tenant, its agents, servants, employees, 
or invitees ("Tenant Parties"), except to the extent caused by negligence or 
willful misconduct of Landlord Parties. Tenant further agrees to indemnify 
and hold Landlord harmless from, and defend Landlord against, any and all 
claims, losses, or liabilities (including damage to Landlord's property) 
arising from (x) any breach of this Lease by Tenant and/or (y) the conduct of 
any work or business of Tenant Parties in or about the Project, including, 
but not limited to any release, discharge, storage or use of any hazardous 
substance, hazardous waste, toxic substance, oil, explosives, asbestos, or 
similar material.

          (d) Tenant shall procure at its cost and expense and keep in effect 
during the Term the following insurance: (i) commercial general liability 
insurance including contractual liability with a minimum combined single 
limit of liability of Two Million Dollars ($2,000,000). Such insurance shall 
name Landlord as an additional insured, shall specifically include the 
liability assumed hereunder by Tenant, and shall provide that it is primary 
insurance, and not excess over or contributory with any other valid, existing 
and applicable insurance in force for or on behalf of Landlord, and shall 
provide that Landlord shall receive thirty (30) days' written notice from the 
insurer prior to any cancellation or change of coverage; (ii) "all risk" 
property insurance (including without limitation, boiler and machinery (if 
applicable); sprinkler damage, vandalism and malicious mischief) on all 
leasehold improvements installed in the Premises by Tenant at its expense (if 
any), and on all Tenant's personal property. Such insurance shall be an 
amount equal to full replacement cost of the aggregate of the foregoing and 
shall provide coverage comparable to the coverage in the standard ISO All 
Risk form, when such form is supplemented with the coverages required above; 
(iii) worker's compensation insurance; and (iv) such other insurance as may  
be required by the law. Tenant shall deliver policies of such insurance or 
certificates thereof to Landlord on or before the Commencement Date, and 
thereafter at least thirty (30) days before the expiration dates of expiring 
policies; and, in the event Tenant shall fail to procure such insurance, or 
to deliver such policies or certificates, Landlord may, at its option, 
procure same for the account of Tenant, and the cost thereof shall be paid to 
Landlord as Additional Charges within five (5) days after delivery to Tenant 
of bills therefor.

                            Lease Agreement - Page 8

<PAGE>

          (e) The provisions of this paragraph 10 shall survive the 
expiration or termination of this Lease with respect to any claims or 
liability occurring prior to such expiration or termination.

     11. WAIVER OF SUBROGATION. Landlord and Tenant ("Claiming Party") each 
waive (i) their right against the other party ("Other Party") and any party 
who would have a claim against the Other Party, and (ii) any subrogation 
right of their insurance company, to recover for any damages in respect of 
injury to persons or property, or for loss of rents or business interruption, 
to the extent of receipt by the Claiming Party of proceeds of insurance in 
respect of such damages. Landlord and Tenant shall each obtain from their 
respective insurers under all policies of fire, theft, and other property 
insurance maintained by either of them at any time during the Term insuring 
or covering the Building or any portion thereof of its contents therein, a 
waiver of all rights of subrogation which the insurer of one party might 
otherwise, if at all, have against the other party, and Landlord and Tenant 
shall each indemnify the other against any loss or expense, including 
reasonable attorney's fees, resulting from the failure to obtain such waiver.

     12. SERVICES AND UTILITIES.

          (a) Landlord shall provide the maintenance and repairs described in 
paragraph 7(a), except for damage occasioned by the act of Tenant, which 
damage shall be repaired by Landlord at Tenant's expense.

          (b) Subject to the provisions elsewhere herein contained and to the 
rules and regulations of the Building, Tenant shall be responsible for 
arranging for, and direct payment of the cost of, garbage pickup, janitorial, 
water, electricity, gas, telephone and any and all other utilities and 
services; and, Landlord shall cooperate with Tenant's efforts to arrange such 
services. Tenant agrees at all times to cooperate fully with Landlord and to 
abide by all the reasonable regulations and requirements which Landlord may 
prescribe for the proper functioning and protection of the heating, 
ventilating and air conditioning system.

          (c) Tenant will not without the written consent of Landlord, which 
consent shall not be unreasonably withheld or delayed, use any apparatus or 
device in the Premises which, when used, puts an excessive load on the 
Building or its structure or systems.

          (d) Landlord shall not be in default hereunder or be liable for any 
damages directly or indirectly resulting from, nor shall the rental herein 
reserved be abated by reason of (i) the installation, use or interruption of 
use of any equipment in connection with the foregoing utilities and services; 
(ii) failure to furnish or delay in furnishing any services to be provided by 
Landlord when such failure or delay is caused by Acts of God or the elements, 
labor disturbances of any character, any other accidents or other conditions 
beyond the reasonable control of Landlord, or by the making of repairs or 
improvements to the Premises or to the Building; or (iii) the limitation, 
curtailment, rationing or restriction on use of water or electricity, gas or 
any other form of energy or any other service or utility whatsoever serving 
the Premises or the Building. Furthermore, Landlord shall be entitled to 
cooperate voluntarily in a reasonable manner with the efforts of national, 
state or local governmental agencies or utilities suppliers in reducing 
energy or other resources consumption.

     13. TENANTS CERTIFICATES. Tenant, at any time and from time to time, 
within ten (10) days from receipt of written notice from Landlord, will 
execute, acknowledge and deliver to Landlord and, at Landlord's request, to 
any prospective tenant, purchaser, ground or underlying lessor or mortgagee 
of any part of the Building or the land upon which the Building is located or 
any other party acquiring an interest in Landlord, a certificate of Tenant in 
the form attached as EXHIBIT "D" and also containing any other information 
that may reasonably be required by any of such persons. It is intended that 
any such certificate of Tenant delivered pursuant to this Paragraph 13 may be 
relied upon by Landlord and any prospective tenant, purchaser, ground or 
underlying lessor or mortgage of any part of the Building or the land upon 
which the Building is located, or such other party.

     14. HOLDING OVER. Any holding over after the expiration of the Term with 
the consent of Landlord shall be construed to be a tenancy from month to 
month at one hundred twenty-five percent (125%) of the Rent herein specified 
unless Landlord shall specify a different rent in its sole discretion, 
together with an amount estimated by Landlord for the monthly Rent and 
Additional Charges payable under this Lease, and shall otherwise be on the 
terms and conditions herein specified so far as applicable. Any holding over 
without Landlord's consent shall constitute a default by Tenant and entitle 
Landlord to re-enter the Premises as provided in Paragraph 19.

     15. SUBORDINATION. Without the necessity of any additional document 
being executed by Tenant for the purpose of effecting a subordination, this 
Lease shall be subject and subordinate at all times to: (i) all ground leases 
or underlying leases which may now exist or hereafter be executed affecting 
the Building or the land upon which the Building is situated or both; and 
(ii) the lien of any mortgage or deed of trust which may now exist or 
hereafter be executed in any amount for which the Building, land, ground 
leases or underlying leases, or Landlord's interest or estate in any of said 
items, is specified as security. Notwithstanding the foregoing, Landlord 
shall have the right to subordinate or cause to be subordinated any such 
ground leases or underlying leases or any such liens to this Lease. In the 
event that any ground lease or underlying lease terminates for any reason or 
any mortgage or deed of trust is foreclosed or a conveyance in lieu of 
foreclosure is made for any reason, Tenant shall, notwithstanding any

                            Lease Agreement - Page 9

<PAGE>

subordination, attorn to and become the Tenant of the successor in interest 
to Landlord at the option of such successor in interest, and Tenant shall be 
entitled to continue in possession of the Premises on the terms and 
conditions of this Lease if and for so long as Tenant fully performs all of 
its obligations hereunder. Tenant covenants and agrees to execute and deliver 
upon demand by Landlord and in the form requested by Landlord, any additional 
documents evidencing the priority or subordination of this Lease with respect 
to any such ground leases or underlying leases or the lien of any such 
mortgage or deed of trust so long as Tenant is provided with a reasonable 
non-disturbance provision. Tenant hereby irrevocably appoints Landlord as 
attorney-in-fact of Tenant to execute, deliver and record any such documents 
in the name of and on behalf of Tenant if Tenant has not executed the same 
within twenty (20) days after Landlord's written request.

      16.  RULES AND REGULATIONS.  Tenant shall faithfully observe and comply 
with the rules and regulations attached to this Lease as EXHIBIT "C" and all 
reasonable modifications thereof and additions thereto from time to time put 
into effect by Landlord. Landlord shall not be responsible for the 
nonperformance by any other Tenant or occupant of the Building or the Project 
of any said rules and regulations. In the event of an express and direct 
conflict between the terms, covenants, agreements and conditions of this 
Lease and those set forth in the rules and regulations, as modified and 
amended from time to time by Landlord, this Lease shall control.

      17.  RE-ENTRY BY LANDLORD.  Except in the case of emergency and upon 
reasonable advance notice to Tenant, Landlord reserves and shall at all times 
have the right to re-enter the Premises to inspect the same, to supply 
janitor service and any other service to be provided by Landlord to Tenant 
hereunder, to show the Premises to prospective purchasers, mortgagees or 
tenants, to post notices of nonresponsibility or as otherwise required or 
allowed by this Lease or by law, and to alter, improve or repair the Premises 
and any portion of the Building and may for that purpose erect, use, and 
maintain scaffolding, pipes, conduits, and other necessary structures in and 
through the Premises where reasonably required by the character of the work 
to be performed. Landlord shall not be liable in any manner for any 
inconvenience, disturbance, loss of business, nuisance or other damage 
arising from Landlord's entry and reasonable acts pursuant to this Paragraph 
and Tenant shall not be entitled to an abatement or reduction of rent or 
Additional Charges if Landlord exercises any rights reserved in this 
paragraph. 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, except for Landlord's gross negligence or willful misconduct. For 
each of the aforesaid purposes, Landlord shall at all times have and retain a 
key with which to un-lock all of the doors, in upon and about the Premises, 
excluding Tenant's vaults and safes, or special security areas (designated in 
advance), and Landlord shall have the right to use any and all means which 
Landlord may deem necessary or proper to open said doors in an emergency, in 
order to obtain entry to any portion of the Premises, and any entry to the 
Premises, or portion thereof obtained by Landlord by any of said means, or 
otherwise, shall not under any emergency circumstances be construed or deemed 
to be a forcible or unlawful entry into, or a detainer of, the Premises, or 
an eviction, actual or constructive, of Tenant from the Premises or any 
portions thereof.

      18.  INSOLVENCY OR BANKRUPTCY.  The appointment of a receiver to take
possession of all or substantially all of the assets of Tenant, or an 
assignment of Tenant for the benefit of creditors, or any action taken or 
suffered by Tenant under any insolvency, bankruptcy, reorganization or other 
debtor relief proceedings, whether now existing or hereafter amended or 
enacted, shall at Landlord's option constitute a breach of this Lease by 
Tenant. Upon the happening of any such event or at any time thereafter, this 
Lease shall terminate five (5) days after written notice of termination from 
Landlord to Tenant. In no event shall this Lease be assigned or assignable 
by operation of law or by voluntary or involuntary bankruptcy proceedings or 
otherwise and in no event shall this Lease or any rights or privileges 
hereunder be an asset of Tenant under any bankruptcy, insolvency, 
reorganization or other debtor relief proceedings.

      19.  DEFAULT.  The failure to perform or honor any covenant, condition 
or representation made under this Lease shall constitute a default hereunder 
by Tenant upon expiration of the appropriate grace period hereinafter 
provided. Tenant shall have a period of three (3) business days from the date 
of written notice from Landlord within which to cure any default in the 
payment of Rent or Additional Charges. Tenant shall have a period of thirty 
(30) days from the date of written notice from Landlord within which to cure 
any other default under this Lease; provided, however, that with respect to 
any default other than the payment of Rent or Additional Charges that cannot 
reasonably be cured within thirty (30) days, the default shall not be deemed 
to be uncured if Tenant commences to cure within thirty (30) days from 
Landlord's notice and continues to prosecute diligently the curing thereof. 
Upon an uncured default of this Lease by Tenant, Landlord shall have the 
following rights and remedies in addition to any other rights or remedies 
available to Landlord at law or in equity:

      (a) The rights and remedies provided by California Civil Code, Section
1951.2, including but not limited to, recovery of the worth at the time of 
award of the amount by which the unpaid Rent and Additional Charges for the 
balance of the Term after the time of award exceeds the amount of rental loss 
for the same period that the Tenant proves could be reasonably avoided, as 
computed pursuant to subsection (b) of said Section 1951.2;

                  Lease Agreement - Page 10
<PAGE>
      (b) The rights and remedies provided by California Civil Code, Section
1951.4, that allows Landlord to continue this Lease in effect and to enforce 
all of its rights and remedies under this Lease, including the right to 
recover Rent and Additional Charges as they become due, for so long as 
Landlord does not terminate Tenant's right to possession; provided, however, 
if Landlord elects to exercise its remedies described in this Paragraph 19(b) 
and Landlord does not terminate this Lease, and if Tenant requests Landlord's 
consent to an assignment of this Lease or a sublease of the Premises at such 
time as Tenant is in default, Landlord shall not unreasonably withhold its 
consent to such assignment or sublease. Acts of maintenance or preservation, 
efforts to relet the Premises or the appointment of a receiver upon 
Landlord's initiative to protect its interest under this Lease shall not 
constitute a termination of Tenant's rights to possession;

            (c) The right to terminate this Lease by giving notice to Tenant in
accordance with applicable law;

            (d) The right and power, as attorney-in-fact for Tenant, to enter 
the Premises and remove therefrom all persons and property and, to store such 
property in a public warehouse or elsewhere at the cost of and for the 
account of Tenant, and to sell such property and apply such proceeds 
therefrom pursuant to applicable California law. Landlord, as 
attorney-in-fact for Tenant, may from time to time sublet the Premises or any 
part thereof for such term or terms (which may extend beyond the Term) and at 
such rent and such other terms as Landlord in its sole discretion may deem 
advisable, with the right to make alterations and repairs to the Premises. 
Upon each such subletting, (i) Tenant shall be immediately liable to pay to 
Landlord, in addition to indebtedness other than Rent and Additional Charges 
due hereunder, the cost of such subletting and such reasonable alterations 
and repairs incurred by Landlord and the amount, if any, by which the Rent 
and Additional Charges due hereunder for the period of such subletting (to 
the extent such period does not exceed the Term) exceeds the amount to be 
paid as Rent and Additional Charges for the Premises for such period; or (ii) at
the option of Landlord, rents received from such subletting shall be applied 
first, to payment of any indebtedness other than Rent and Additional Charges 
due hereunder from Tenant to Landlord, second, to the payment of any costs of 
such subletting and of such alterations and repairs, third, to payment of 
Rent and Additional Charges due, and unpaid hereunder; and the residue, if 
any, shall be held by Landlord and applied in payment of future Rent and 
Additional Charges as the same becomes due hereunder. If Tenant has been 
credited with any rentals to be received by such subletting under option (i) and
such rentals shall not be promptly paid to Landlord by the subtenant(s), 
or if such rentals received from such subletting under option (ii) during any 
month be less than that to be paid during that month by Tenant hereunder, 
Tenant shall pay any such deficiency to Landlord. Such deficiency shall be 
calculated and paid monthly. For all purposes set forth in this paragraph 
(d), Landlord is hereby irrevocably appointed attorney-in-fact for Tenant, 
with power of substitution. The taking possession of the Premises by 
Landlord, as attorney-in-fact for Tenant, shall not be construed as an 
election on its part to terminate this Lease unless a written notice of such 
intention be given to Tenant. Notwithstanding any such subletting without 
termination, Landlord may at any time thereafter elect to terminate this 
Lease for such previous breach; and,

            (e) The right to have receiver appointed for Tenant, upon 
application by Landlord, to take possession of the Premises and to apply any 
rental collected from the Premises and to exercise all other rights and 
remedies granted to Landlord as attorney-in-fact for Tenant pursuant to 
subparagraph (d) above.

Landlord shall have a period of thirty (30) days from the date of written 
notice from Tenant within which to cure any default under this Lease; 
provided, however, that with respect to any default that cannot reasonably be 
cured within thirty (30) days, the default shall not be deemed to be uncured 
if Landlord commences to cure within thirty (30) days from Tenant's notice 
and continues to prosecute diligently the curing thereof. Tenant agrees to 
give any Mortgagee and/or Trust Deed Holders ("Mortgagee"), by Registered 
Mail, a copy of any Notice of Default served upon the Landlord, provided that 
prior to such notice Tenant has been notified in writing, (by way of Notice 
of Assignment of Rents and Leases, or otherwise) of the address of such 
Mortgagee. Tenant further agrees that if Landlord shall have failed to cure 
such default within the time provided for in this Lease, then the Mortgagee 
shall have an additional thirty (30) days within which to cure such default 
or if such default cannot be cured within that time, then such additional 
time as may be necessary to cure such default shall be granted if within such 
thirty (30) days Mortgagee has commenced and is diligently pursuing the 
remedies necessary to cure such default (including, but not limited to, 
commencement of foreclosure proceedings, if necessary to effect such cure), 
in which event the Lease shall not be terminated while such remedies are 
being diligently pursued.

      20.  DAMAGE BY FIRE, ETC.  If the Premises or the Building are damaged 
by fire or other casualty, Landlord shall forthwith repair the same, provided 
that such repairs can be made within one hundred eighty (180) days after the 
date of such damage under the laws and regulations of the federal, state and 
local governmental authorities having jurisdiction thereof. In such event, 
this Lease shall remain in full force and effect except that Tenant shall be 
entitled to a proportionate reduction of Rent and Additional Charges while 
such repairs to be made hereunder by Landlord are being made. Such reduction 
of rent, if any, shall be based upon the proportion that the area of the 
Premises rendered untenantable by such damage bears to the total area of the 
Premises. Within twenty (20) days after the date of such damage, Landlord 

                           Lease Agreement - Page 11

<PAGE>

shall notify Tenant whether or not such repairs can be made within one 
hundred eighty (180) days after the date of such damage and Landlord's 
determination thereof shall be binding on Tenant. If such repairs cannot be 
made within one hundred eighty (180) days from the date of such damage, 
Landlord shall have the option within thirty (30) days after the date of such 
damage either to: (i) notify Tenant of Landlord's intention to repair such 
damage and diligently prosecute such repairs, in which event this Lease shall 
continue in full force and effect and the Rent and Additional Charges shall 
be reduced as provided herein; or (ii) notify Tenant of Landlord's election 
to terminate this Lease as of a date specified in such notice, which date 
shall not be less than thirty (30) days nor more that sixty (60)days after 
notice is given. In the event that such notice to terminate is given by 
Landlord, this Lease shall terminate on the date specified in such notice. If 
Landlord cannot make such repairs within one hundred eighty (180) days, then 
Tenant shall have the right to terminate the lease by providing written notice 
to Landlord of such termination within the later of thirty (30) days following 
Tenant's receipt of Landlord's notice of the time to repair or five (5) days 
after Landlord's notice of its intent to repair, or not to repair, the 
Premises. Such notice of intent to repair may be conditional upon Tenant's 
agreement not to terminate the lease. In case of termination by either event, 
the Rent and Additional Charges shall be reduced by a proportionate amount 
based upon the extent to which such damage interfered with the business 
carried on by Tenant in the Premises, and Tenant shall pay such reduced Rent 
and Additional Charges up to the date of termination. Landlord agrees to 
refund to Tenant any Rent and Additional Charges previously paid for any 
period of time subsequent to such date of termination. The repairs to be made 
hereunder by Landlord shall not include, and Landlord shall not be 
required to repair, any damage by fire or other cause to the property of 
Tenant or any repairs or replacements of any paneling, decorations, railings, 
floor coverings or any alterations, additions, fixtures or improvements 
installed on the Premises by or at the expense of Tenant. Tenant hereby 
waives the provisions of Section 1932.2, and Section 1933.4, of the Civil 
Code of California. Notwithstanding anything contained herein to the 
contrary, if a Major Casualty occurs with respect to any portion of the 
Building, and the net insurance proceeds obtained as a result of such casualty
are ninety percent (90%) or a lesser percentage of the cost of restoration, 
rebuilding or replacement, then Landlord shall not be obligated to undertake 
such restoration, rebuilding or replacement unless Landlord elects to do so 
in writing. For the purpose of this Lease, a "Major Casualty" shall mean a 
casualty that renders unusable twenty percent (20%) or more of the Net 
Rentable Area of the Building or which materially adversely affects the use 
of such Building.

      21.  EMINENT DOMAIN.  If any part over 15% of the Premises shall be 
taken or appropriated under the power of eminent domain or conveyed in lieu 
thereof, either party shall have the right to terminate this Lease at its 
option. If any part of the Building shall be taken or appropriated under 
power of eminent domain or conveyed in lieu thereof, Landlord may terminate 
this Lease at its option. In either of such events, Landlord shall receive 
(and Tenant shall assign to Landlord upon demand from Landlord) any income, 
rent, award or any interest therein which may be paid in connection with the 
exercise of such power of eminent domain, and Tenant shall have no claim 
against Landlord for any part of sum paid by virtue of such proceedings, 
whether or not attributable to the value of the unexpired term of this Lease, 
except that Tenant shall be entitled to petition the condemning authority for 
the following: (i) the unamortized cost of any tenant improvements paid for 
by Tenant (and not reimbursed by Landlord); (ii) the value of Tenant's trade 
fixtures; and, (iii) Tenant's relocation costs. If a part of the Premises 
shall be so taken or appropriated or conveyed and neither party hereto shall 
elect to terminate this Lease and the Premises have been damaged as a 
consequence of such partial taking or appropriation or conveyance, Landlord 
shall restore the Premises continuing under this Lease at Landlord's cost and 
expense; provided, however, that Landlord shall not be required to repair or 
restore any injury or damage to the property of Tenant or to make any repairs 
or restoration of any Alterations installed on the Premises by or at the 
expense of Tenant. Thereafter, the Rent and Additional Charges to be paid 
under this Lease for the remainder of the Term shall be proportionately 
reduced, such that thereafter the amounts to be paid by Tenant shall be in 
the ratio that they are of the portion of the Premises not so taken bears to 
the total area of the Premises prior to such taking. Notwithstanding anything 
to the contrary contained in this Paragraph 21, if the temporary use or 
occupancy of any part of the Premises shall be taken or appropriated under 
power of eminent domain during the Term, this Lease shall be and remain 
unaffected by such taking or appropriation and Tenant shall continue to pay 
in full all Rent and Additional Charges payable hereunder by Tenant during 
the term; in the event of any such temporary appropriation or taking. Tenant 
shall be entitled to receive that portion of any award which represents 
compensation for the use of or occupancy of the Premises during the Term, and 
Landlord shall be entitled to receive that portion of any award which 
represents the cost of restoration of the Premises and the use and occupancy 
of the Premises after the end of the Term.

      22.  SALE BY LANDLORD.  In the event of a sale or conveyance by 
Landlord of the Building, any such sale or conveyance shall operate to 
release Landlord from any future liability upon any of the covenants or 
conditions, express or implied, herein contained in favor of Tenant, and in 
such event Tenant agrees to look solely to the successor in interest of 
Landlord in and to this Lease. This Lease shall not be affected by any such 
sale, and Tenant agrees to attorn to the purchaser or assignee.

                  Lease Agreement - Page 12
<PAGE>

     23. RIGHT OF LANDLORD TO PERFORM.  All covenants and agreements to be 
performed by Tenant under any of the terms of this Lease shall be performed 
by Tenant at Tenant's sole cost and expense and without any abatement of rent 
or additional charges. If Tenant shall fail to pay any sum of money, other 
than rent or additional charges, required to be paid by it hereunder or shall 
fail to perform any other act on its part to be performed hereunder, and such 
failure shall continue for thirty (30) days after notice thereof by Landlord, 
Landlord may, but shall not be obligated so to do, and without waiving or 
releasing Tenant from any obligations of Tenant, make any such payment or 
perform any such act on Tenant's part to be made or performed as provided in 
this Lease. All sums so paid by Landlord and all necessary incidental costs 
together with interest thereon at the maximum rate permitted by law, from the 
date of such payment by Landlord shall be payable as additional charges to 
Landlord on demand.

     24. SURRENDER OF PREMISES.

         (a) At the end of the Term or any renewal thereof or other sooner 
termination of this Lease, Tenant will peaceably deliver to Landlord 
possession of the Premises, together with all improvements or additions upon 
or belonging to the same, by whomsoever made, in the same condition as 
received, or first installed, subject to normal wear and tear and the rights 
and obligation of Tenant concerning casualty damage pursuant to Paragraph 
20, damage by fire, earthquake, Act of God, or the elements alone excepted. 
Tenant may, upon the termination of this Lease, remove all movable furniture 
and equipment belonging to Tenant, at Tenant's sole cost, title to which 
shall be in Tenant until such termination, provided that Tenant repairs any 
damage caused by such removal. Property not so removed shall be deemed 
abandoned by Tenant, and title to the same shall thereupon pass to Landlord. 
Upon request by Landlord, and unless otherwise agreed to in writing by 
Landlord, Tenant shall remove, at Tenant's sole cost, any or all Alterations 
to the Premises installed by or at the expense of Tenant and all movable 
furniture and equipment belonging to Tenant which may be left by Tenant and 
repair any damage resulting from such removal.

         (b) The voluntary or other surrender of this Lease by Tenant, or a 
mutual cancellation thereof, shall not work a merger, and shall, at the 
option of Landlord, terminate all or any existing subleases or subtenancies, 
or may, at the option of Landlord, operate as an assignment to it of any or 
all such subleases or subtenancies.


     25. WAIVER. If either Landlord or Tenant waives the performance of any 
term, covenant or condition contained in this Lease, such waiver shall not be 
deemed to be a waiver of any subsequent breach of the same or any other term, 
covenant or condition contained herein. Furthermore, the acceptance of Rent 
or Additional Charges by Landlord shall not constitute a waiver of any 
preceding breach by Tenant of any term, covenant or condition of this Lease, 
regardless of Landlord's knowledge of such preceding breach at the time 
Landlord accepted such Rent or Additional Charges. Failure by Landlord to 
enforce any of the terms, covenants or conditions of this Lease for any 
length of time shall not be deemed to waive or to decrease the right of 
Landlord to insist thereafter upon strict performance by Tenant. Waiver by 
Landlord or any term, covenant or condition contained in this Lease may only 
be made by a written document signed by Landlord.

     26. NOTICES. Except as otherwise expressly provided in this Lease, any 
bills, statements, notices, demands, requests or other communications given or 
required to be given under this Lease shall be effective only if rendered or 
given in writing, sent by registered or certified mail or delivered 
personally, (i) to Tenant (A) at Tenant's address set forth in the Basic 
Lease Information, if sent prior to Tenant's taking possession of the 
Premises, or (B) at the Premises if sent subsequent to Tenant's taking

the Premises; or (ii) to Landlord at Landlord's address set forth in the 
Basic Lease Information; or (iii) to such other address as either Landlord or 
Tenant may designate as its new address for such purpose by notice given to 
the other in accordance with the provisions of this Paragraph 27. Any such 
bill, statement, notice, demand, request or other communication shall be 
deemed to have been rendered or given two (2) days after the date when it 
shall have been mailed as provided in this Paragraph 27 if sent by registered 
or certified mail, or upon the date personal delivery is made. If Tenant is 
notified of the identity and address of Landlord's mortgagee or ground or 
underlying lessor, Tenant shall give to such mortgagee or ground or 
underlying lessor notice of any default by Landlord under the terms of this 
Lease in writing sent by registered or certified mail, and such mortgagee or 
ground or underlying lessor shall be given a reasonable opportunity to cure 
such default prior to Tenant exercising any remedy available to it.

     27.  TAXES PAYABLE BY TENANT. 

     At lease ten (10) days prior to delinquency Tenant shall pay all taxes 
levied or assessed upon Tenant's equipment, furniture, fixtures and other 
personal property located in or about the Premises. If the assessed value of 
Landlord's property is increased by the inclusion therein of a value placed 
upon Tenant's equipment, furniture, fixtures or other personal property, 
Tenant shall pay to Landlord, upon written demand, the taxes so levied 
against Landlord, or the proportion thereof resulting from said increase in 
assessment.

     28. ABANDONMENT. Tenant shall not abandon the Premises at any time 
during the Term, and if Tenant shall abandon or surrender the Premises or be

<PAGE>

Landlord, be deemed to be abandoned and title thereto shall thereupon pass to 
Landlord, except such property as may be mortgaged to Landlord. 
Notwithstanding anything to the contrary contained herein, Tenant shall not 
be allowed to vacate the Premises is such would result in a termination of 
Landlord's insurance. Upon receiving Tenants request for such, Landlord shall 
request that its insurer notify Tenant whether vacating the Premises will 
result in a cancellation of the Building's insurance for the current policy 
year.

     29. SUCCESSORS AND ASSIGNS.  Subject to the provisions of Paragraph 9, 
the terms, covenants and conditions contained herein shall be binding upon 
and insure to the benefit of the parties hereto and their respective legal 
and personal representatives, successors and assigns.

     30. ATTORNEY'S FEES. If Tenant or Landlord brings any action for any 
relief against the other, declaratory or otherwise, arising out of this 
Lease, including any suit by Landlord for the recovery of Rent or Additional 
Charges or possession of the Premises, the losing party shall pay to the 
prevailing party a reasonable sum for attorney's fees, which shall be deemed 
to have accrued on the commencement of such action and shall be paid whether 
or not the action is prosecuted to judgment.

     31. LIGHT AND AIR. Tenant covenants and agrees that no diminution of 
light, air or view by any structure which may hereafter be erected (whether 
or not by Landlord) shall entitle Tenant to any reduction of rent under this 
Lease, result in any liability of Landlord to Tenant, or in any other way 
affect this Lease or Tenant's obligations hereunder.

     32. SECURITY DEPOSIT. Concurrently with Tenant's execution of this 
Lease, Tenant shall deposit with Landlord the sum specified in the Basic 
Lease Information, which sum shall be held by Landlord as a security deposit 
for the faithful performance by Tenant of all the terms, covenants and 
conditions of this Lease to be kept and performed by Tenant. Tenant agrees 
that Landlord may apply the security deposit to remedy any failure by Tenant 
to repair or maintain the Premises or to perform any other terms, covenants 
and conditions contained herein. If Tenant is in compliance with all terms, 
covenants and conditions of this lease at the expiration of the Term, 
Landlord will, within thirty (30) days after the termination hereof, promptly 
return the security deposit to Tenant or the last permitted assignee of 
Tenant's interest hereunder at the expiration of the Term. Should Landlord 
use any portion of the security deposit to cure any default by Tenant 
hereunder, Tenant shall within ten (10) days replenish the security deposit 
to the original amount; Tenant's failure to do so shall be a material breach 
of this Lease. Landlord shall not be required to keep the security deposit 
separate from its general funds, and Tenant shall not be entitled to interest 
on any such deposit. Upon the occurrence of any events of default described 
in Paragraph 19 of this Lease the security deposit may be applied by Landlord 
to the extent required to compensate Landlord for damages incurred, or to 
reimburse Landlord as provided herein, in connection with any such event of 
default.

manner similar to current tenants (Formtek and Lockheed). Any sign must 
conform to all applicable codes, ordinances, and C,C&R's and be approved by 
Landlord (size, color, placement, style, etc.) prior to installation.

     40. OPTION TO RENEW. Upon the condition that Tenant is not then in 
default under the Lease beyond any applicable grace period, Tenant shall have 
two (2) options to renew the Lease for a period of five (5) years each 
("Extension Terms"). The exercise of said options shall require not less than 
twelve (12) months prior written notice from Tenant to Landlord prior to the 
expiration of the term preceding said Extension Term. In such written notice, 
Tenant must unconditionally elect to extend the Term. The Monthly Base Rent 
for the Extension Term shall be the greater of (i) the Fair Market Rental 
Value or (ii) the rental rate in effect during the last month of the Term 
immediately preceding the Extension Term. The Fair Market Rental Value shall 
be determined as noted below:

     41. FAIR MARKET RENTAL VALUE. For the purposes of the Lease, the term 
"Fair Market Rental Value" shall mean the annual amount per rentable square 
foot that Landlord has accepted in current transactions between 
non-affiliated parties from new, non-expansion, non-renewal and non-equity 
tenants of comparable credit-worthiness, for comparable space, for a 
comparable use for a comparable period of time ("Comparable Transactions") in 
the Building, of if there are not a sufficient number of Comparable 
Transactions in the Building, what a comparable landlord of a comparable 
building in the vicinity of the Building in Moffett Park area of Sunnyvale 
would accept in Comparable Transactions. In any determination of Comparable 
Transactions appropriate consideration shall be given to the annual rental 
rates per rentable square foot, the standard of measurement by which the 
rentable square footage is measured, the ratio of rentable square footage to 
useable square footage, the type of escalation clause, the efficiency of the 
space (i.e. whether increases in additional rent are determined on a net or 
gross basis, and if gross, whether such increases are determined according to 
a base year or base dollar expense stop), the extent of Tenant's liability 
under the Lease, abatement provisions reflecting free rent, length of the 
lease term, size and location of the premises being leased, level and 
suitability of tenant improvements (and reflecting the restoration allowance 
provided for in Paragraph 5), extent of service provided, and other generally 
applicable conditions of tenancy for such Comparable Transactions. The intent 
is that Tenant will pay the same rent that would otherwise be paid in 
Comparable Transactions.

Landlord shall provide written notice of Tenant of Landlord's opinion of Fair 
Market Rental Value within thirty (30) days after Tenant provides the notice 
to Landlord exercising Tenant's option rights which require a calculation of 
the Fair Market Rental Value; provided, however, Landlord shall not be 
obligated to provide such notice more than twelve (12) months before the date 
when the Fair Market Rental Value is to become effective. Tenant shall have 
fifteen (15) days ("Tenant's Review Period") after receipt of Landlord's 
notice of the new rental within which to accept such rental. In the event 
Tenant fails to accept in writing such rental proposed by Landlord then such 
proposal shall be deemed rejected, and Landlord and Tenant shall attempt to 
agree upon such Fair Market Rental Value, using their best good faith 
efforts. If Landlord and Tenant fail to reach agreement within fifteen (15) 
days following Tenant's Review Period ("Outside Agreement Date"), then each 
party shall place in a separate sealed envelope their final proposal as to 
Fair Market Rental Value and such determination shall be submitted to 
arbitration in accordance with subsections (a) through (e) below.


                        Lease Agreement - Page 15

<PAGE>

In the event that Landlord fails to timely generate the initial written 
notice of Landlord's opinion of the Fair Market Rental Value which triggers 
the negotiation period of this Paragraph, then Tenant may commence such 
negotiations by providing the initial notice, in which event Landlord shall 
have fifteen (15) days ("Landlord's Review Period") after receipt of Tenant's 
notice of the new rental within which to accept such rental. In the event 
Landlord fails to accept in writing such rental proposed by Tenant, then such 
proposal shall be deemed rejected, and Landlord and Tenant shall attempt in 
good faith to agree upon such Fair Market Rental Value, using their best good 
faith efforts. If Landlord and Tenant fail to reach agreement within fifteen 
(15) days following Landlord's Review Period (which shall be, in such event, 
the "Outside Agreement Date" in lieu of the above definition of such date), 
then each party shall place in a separate sealed envelope their final 
proposal as to Fair Market Rental Value and such determination shall be 
submitted to arbitration in accordance with subsections (a) through (e) below.

     (a) Landlord and Tenant shall meet with each other within five (5) 
business days of the Outside Agreement Date and exchange the sealed envelopes 
and then open such envelopes in each other's presence. If Landlord and Tenant 
do not mutually agree upon the Fair Market Rental Value within one (1) 
business day of the exchange and opening of envelopes, then, within ten (10) 
business days of the exchange and opening of the envelopes Landlord and 
Tenant shall agree upon and jointly appoint a single arbitrator who shall by 
profession be a real estate lawyer or broker who shall have been active over 
the five (5) year period ending on the date of such appointment in the 
leasing of commercial office properties in the vicinity of the Building. 
Neither Landlord nor Tenant shall consult with such broker or lawyer as to 
his or her opinion as to Fair Market Rental Value prior to the appointment. 
The determination of the arbitrator shall be limited solely to the issue of 
whether Landlord's or Tenant's submitted Fair Market Rental Value for the 
Leased Premises is the closest to the actual Fair Market Value for the Leased 
Premises as determined by the arbitrator, taking into account the 
requirements of this Paragraph. Such arbitrator may hold such hearings and 
require such briefs as the arbitrator, in his or her sole discretion, determines
is necessary. In addition, Landlord or Tenant may submit to the arbitrator 
with a copy to the other party within five (5) business days after the 
appointment of the arbitrator any market data and additional information that 
such party deems relevant to the determination of Fair Market Rental Value 
("FMRV Data") and the other party may submit a reply in writing within five 
(5) business days after receipt of such FMRV Data.

     (b) The arbitrator shall, within thirty (30) days of his or her 
appointment, reach a decision as to whether the parties shall use Landlord's 
or Tenant's submitted Fair Market Rental Value, and shall notify Landlord and 
Tenant of such determination.

     (c) The decision of the arbitrator shall be binding upon Landlord and 
Tenant.

     (d) If Landlord and Tenant fail to agree upon and appoint an arbitrator, 
then the appointment of the arbitrator shall be made by the Presiding Judge 
of the Santa Clara Superior Court, or, if he or she refuses to act, by any 
state or federal judge in whose court venue would be proper to adjudicate a 
dispute over this Lease.

     (e) Landlord and Tenant shall each pay any and all costs incurred by 
either Landlord or Tenant, respectively, in connection with this arbitration; 
provided, however, that the cost of the arbitrator shall be paid by Landlord 
and Tenant equally.

From and after the commencement of the Extension Term, all of the other 
terms, covenants and conditions of the Lease shall also apply; provided, 
however, that (i) Rent shall be revised as herein provided; and (ii) Tenant 
shall have no further rights to extend the Term.

above, without any duty of inquiry or investigation. Except as set forth in 
this Paragraph 42, Landlord has made absolutely no representations or 
warranties to Tenant regarding Hazardous Substances. Landlord represents that 
it has received no written notice of any violation or claimed violation with 
respect to the presence of toxic or Hazardous Substances on, in or under the 
Project or of any pending or contemplated investigation or other action 
relating thereto.

reasonably approve of any and all contractors hired by Tenant to perform such 
remedial work. All such remedial work shall be performed in compliance with

however, that this subparagraph (i) and subparagraph (ii) below shall not 
apply to require any lender acquiring the Landlord's interest in the Premises 
or Property through foreclosure or deed in lieu of foreclosure to indemnify, 
defend or hold harmless Tenant, its officers, employees, and agents (but such 
a lender would continue to release Tenant from any liability for and would 
waive all such claims relating to this subparagraph (i) against Tenant); 
(ii) Hazardous Substances were released or disposed of on, in, or under the 
Premises or Property prior to Tenant's first occupancy unless caused by 
Tenant, its employees, contractors, guests, invitees, sublessees, agents, 
assignees, licensees or servants, or; (iii) the contamination of the Premises 
or Property was caused by the release, disposal, use or storage of Hazardous

thereon, including, without limitation, notice or other written communication 
concerning any actual or threatened investigation, inquiry, lawsuit, claim, 
citation, directive, summons, proceeding, complaint, notice, order, writ or 
injunction, relating to the same, then such party shall deliver to the other 
party, as soon as reasonably possible, but in any event within ten days of 
the receipt of such written notice, copies of any documents evidencing the 
same. 

     (e) Tenant shall not use, without Landlord's reasonable approval, any 
Hazardous Substances within the Building, except for very immaterial amounts 
of Hazardous Substances incidental to its office use, including, but not

EXHIBIT "B"
-------------------------------------------------------------------------------

                                 WORK LETTER

      1. Landlord shall furnish and install the Base Building provided for in 
Paragraph 2 at Landlord's expense and, at Tenant's expense, the additional 
work to complete the Premises ("Tenant Improvements") normally performed by 
the construction trades, required by the plans and specifications approved by 
Landlord and Tenant pursuant to this Work Letter. The quantities, character 
and manner of installation of all of the foregoing work shall be subject to 
the limitations imposed by any applicable regulations, laws, ordinance, codes 
and rules.

     2. The Landlord shall present, and the tenant shall accept, the Building 
on an "as-is" basis except with regard to Landlord's obligations concerning 
code related upgrades, as described in Paragraph 10 hereof, and as otherwise 
provided in the Lease.

     3. Tenant shall provide Landlord's architect and engineers with 
sufficient instructions (see Exhibit B-1) to enable Landlord's architect and 
engineers to prepare complete plans and specifications for the Tenant 
Improvements. The cost of space planning and preparing the working drawings 
for Tenant Improvements or any change to the original instruction and/or plans 
and specifications shall be paid by Tenant.

     4. Subject to the terms of Paragraph 10 hereof, Tenant shall bear the 
cost of Tenant Improvements. Any modifications requested by Tenant to Base 
building work shall be at Tenant's expense.

     5. Landlord and Tenant shall diligently pursue the preparation of all 
plans and specifications for Tenant Improvements. All such plans and 
specifications shall be performed by Landlord's architect and be subject to 
approval by Landlord.

     6. When the plans and specifications are complete and approved by 
Landlord and Tenant, which shall be accomplished on or before Tenant's Plan 
Delivery Date, as specified on the Basic Lease Information, Landlord shall 
obtain a cost estimate for Tenant Improvements from Landlord's contractor, the 
costs and quality of which are within industry standards. If the cost 
estimate exceeds any allowance given by Landlord to Tenant for Tenant 
Improvements and Tenant is obligated to pay for such excess costs, the cost 
estimate shall be submitted to Tenant.  Tenant shall approve or disapprove 
such estimate within three (3) business days. Failure to approve within such 
period shall constitute approval. If disapproved, Tenant shall provide new 
sufficient instruction within such three (3) business days for the revision of 
plans and cost estimates for approval by Tenant. Failure to provide such 
instruction within such period shall entitle Landlord to terminate this 
Lease. Tenant shall be obligated to approve the cost estimate if the cost is 
within any allowance provide by Landlord or any greater budget approved by 
Tenant. If the cost estimate is in excess of the allowance or such greater 
budget, Tenant shall provide new sufficient instruction which will reduce the 
cost estimate for Tenant Improvements to a level acceptable to Tenant and 
within any allowance provided by Landlord within ten (10) days after receipt 
of the cost estimate (or one revision thereof, if Tenant requests a change in 
plans and specifications to reduce costs).

     7. After receipt and approval of Tenant's plans, specifications and cost 
estimate, Landlord shall administer the construction of Tenant Improvements 
in accordance with the plans and specifications; provided, however, that 
Landlord shall not be required to install any Tenant Improvements which do 
not conform to the plans and specifications for the Building, or do not 
conform t
