                                      LEASE

          1. PARTIES. This Lease ("Lease"), dated for reference purposes only,
December 1, 1994, is made by and between OP&F SCHRODER TRUST (herein called
"Lessor"), and NOVAQUEST INFOSYSTEMS, a California corporation (herein called
"Lessee").

          2. LEASE OF PREMISES.

               2.1 PREMISES:

                    (a) Lessor hereby leases to Lessee, and Lessee hereby leases
from Lessor, for the term, at the rental and upon all of the terms and
conditions set forth herein, those certain premises consisting of the area
outlined and cross hatched on the plans attached hereto as Exhibit B-1 and B-2
(the "Primary Premises") which-is a portion of that certain building (the
"Building") located at 19951 Mariner Avenue, in the City of Torrance, County of
Los Angeles, State of California.

                    (b) On the condition that the present tenant, to wit: TRW,
vacates the warehouse space located within the Building and outlined and
cross-hatched on the plan attached hereto as Exhibit B-3 (the "TRW Warehouse
Space"), Lessor hereby leases to Lessee, and Lessee hereby leases from Lessor,
for the term, at the rental and upon all of the terms and conditions set forth
herein the TRW Warehouse Space. In this connection Lessor has prior to the
execution of this Lease served a thirty (30) notice on TRW to vacate the TRW
Warehouse Space, Lessor shall have no other obligation with regard to such space
other than to lease the space to Lessee pursuant to the terms of this Lease if,
as and when it becomes available. In the event TRW fails to vacate such space
this Lease shall continue in full force and effect as to the Primary Premises
and Lessor shall have no liability to Lessee as a consequence of such failure.
In the event TRW vacates the TRW Warehouse Space and as a consequence Lessor
leases the same to Lessee as above provided, when Lessor makes the TRW Warehouse
Space available to Lessee for occupancy the term "Premises" as used in this
Lease shall mean the Primary Premises together with the TRW Warehouse Space. In
the event TRW does not vacate the TRW Warehouse Space and Lessor only leases the
Primary Premises to Lessee pursuant to this Lease, the term "Premises" as used
in this Lease shall mean the Primary Premises.

                    (c) The Premises, the portion of the Building outside the
Premises, and the Common Area (as defined in Subparagraph 2.3 below), are herein
collectively referred to as the "Building Project." The real property on which
the Building Project is located (the "Land") is legally described in Exhibit A
attached hereto.

               2.2 VEHICLE PARKING. Lessee shall be entitled to 100 vehicle
parking spaces (93 of which are allocated to the Primary Premises and 7 of which
are allocated to the TRW Warehouse Space), unreserved and unassigned, on those
portions of the
<PAGE>

Common Area designated by Lessor for parking. In the event TRW does not
vacate the TRW Warehouse Space Lessee shall not be entitled to the 7 parking
spaces allocated to the TRW Warehouse Space. Lessee shall not use more
parking spaces than the number of spaces it is entitled to as above set
forth. Said parking spaces shall be used only for parking by vehicles no
larger than full size passenger automobiles or vans or similar size vehicles
which can fit in a single parking space. In no event shall Lessor charge
Lessee for the use of such parking spaces other than for such operating
expenses as are included in Lessee's share of Operating Expenses as described
in Paragraph 4.2 below.

                    (a) Lessee shall not permit or allow any vehicles that
belong to or are controlled by Lessee or Lessee's employees, suppliers,
shippers, customers, or invitees to be loaded, unloaded, or parked in areas
other than those designated by Lessor for such activities.

                    (b) If Lessee permits or allows any of the prohibited
activities described in Paragraph 2.2 of this Lease, then Lessor shall have the
right, in addition to such other rights and remedies that it may have, to remove
or tow away the vehicle involved and charge the cost to Lessee, which cost shall
be immediately payable upon demand by Lessor.

                    (c) All automobiles, trucks, and other vehicles of Lessee,
Lessee's subtenants, concessionaires and licensees and their officers, agents
and employees shall be parked only in such place as may be designated by Lessor
as employee parking areas. If requested by Lessor, Lessee will furnish Lessor
with license numbers of said vehicles.

               2.3 COMMON AREA. The term "Common Area" is defined as all areas
and facilities outside the Building and within the boundary lines of the
Building Project (including the Land) that are provided and designated by Lessor
from time to time for the general non-exclusive use of Lessor, Lessee and of
other lessees of the Building Project and their respective employees, suppliers,
shippers, customers and invitees, including but not limited to parking
structures, parking areas to the extent not otherwise prohibited by this Lease,
loading and unloading areas, trash areas, roadways, sidewalks, walkways,
parkways, ramps, driveways, landscaped areas and decorative or boundary walls
and any other improvements thereon or thereunder.

               2.4 Common Area - Changes. Lessor shall have the right, in
Lessor's sole discretion, from time to time:

                    (a) To make changes to the Common Areas, including, without
limitation, changes in the location, size, shape and number of driveways,
entrances, parking spaces, parking areas, loading and unloading areas, ingress,
egress, direction of traffic, landscaped areas and walkways;

                    (b) To close temporarily any of the Common Areas for
maintenance purposes so long as reasonable access to the Premises remains
available:


<PAGE>

                    (c) To designate other land outside the boundaries of the
Building Project to be a part of the Common Areas;

                    (d) To add additional buildings and improvements to the
Common Areas;

                    (e) To use the Common Areas while engaged in making
additional improvements, repairs or alterations to the Building Project, or any
portion thereof;

                    (f) To do and perform such other acts and make such other
changes in, to or with respect to the Common Areas and Building Project as
Lessor may, in the exercise of sound business judgment, deem to be appropriate.

               2.5 PARKING FACILITIES. Lessor shall at all times provide the
parking facilities required by applicable law and in no event shall the number
of parking spaces that Lessee is entitled to under paragraph 2.2 be reduced.

          3. TERM.

               3.1 TERM AND COMMENCEMENT DATE. The term of this Lease shall
commence December 1, 1994 (the "Commencement Date") and shall terminate December
31, 1997. In the event Lessor cannot deliver possession of the Premises (either
the Primary Premises or the Primary Premises together with the TRW Warehouse
Space, as the case may be) at the time of the execution of this Lease, Lessor
shall not be subject to any liability therefor, nor shall such failure affect
the validity of this Lease, or the obligations of Lessee under the Lease, or
extend the term of the Lease as amended hereby, but in such case, Lessee shall
not, except as otherwise provided herein, be obligated to pay monthly fixed
rental or Lessee's Share of Operating Expenses until possession of the Premises
is delivered to Lessee. In no event shall the term of this lease be extended as
a consequence of Lessee not being able to make the Premises, or any portion
thereof, including, without limitation, the TRW Warehouse Space, available to
Lessee for its occupancy on the Commencement Date. However and not withstanding
the foregoing, in the event Lessor cannot deliver possession of the Primary
Premises on or before December 15, 1994, this Lease, at the option of the
Lessee, shall terminate and be of no further force or effect.

               3.2 CONDITIONS OF PREMISES ON DELIVERY: "AS-IS WHERE-IS" LEASE.

                    (a) Lessor shall deliver the Premises to Lessee in a clean,
broom swept condition with all HVAC, plumbing, electrical and mechanical systems
and equipment in good working order. In addition, Lessor shall repair any leaks
found in the roof system. In the event the Premises are cited by any
governmental authority having jurisdiction in such matters as a consequence of
the Premises not being in compliance


<PAGE>

with the applicable provisions of the Americans With Disabilities Act ("ADA")
and such citation is not received as a consequence of Lessee constructing
Tenant Improvements and/or Alterations (both as defined below) to the
Premises (either pursuant to Paragraphs 7 or 8.4 below or otherwise) Lessor,
at its expense, shall make such modifications to the Premises as are required
in order to comply with ADA or Lessor shall otherwise cause the citation to
be rescinded or waived. In the event such citation is received as a
consequence of Lessee constructing such Tenant Improvements and/or
Alterations, Lessee, at its expense, shall make such modifications to the
Premises as are required in order to comply with ADA or otherwise cause the
citation or order to be rescinded or waived.

                    (b) With the exceptions set forth in subparagraph 3.2 (a)
Lessee acknowledges that it is leasing the Premises in their present "as is
where is" condition. Lessee acknowledges that Lessee is leasing the Premises
solely in reliance on Lessee's own investigation, and that no representations or
warranties of any kind whatsoever, express or implied, have been made by Lessor,
Lessor's agents, or brokers, regarding the condition of the Premises or

and condition of the Premises and agrees to lease the Premises in the condition
that it is in as of the Commencement Date, except as otherwise provided in the
first two sentences of this Paragraph 3.2.

          4. Rent: Other Charges.

               4.1 FIXED ANNUAL RENTAL.

                    (a) Lessee shall pay to Lessor. without prior demand and
without any deduction, set off, or counterclaim whatsoever, for each year of the
term of this Lease, a monthly fixed minimum amount (the "monthly fixed rental";
collectively, the monthly fixed rental and Lessee's Share of Operating Expenses
are referred to as "Rent") determined as set forth below.

                    (b) Except as otherwise provided in Subparagraph 4.1(d)
below, commencing with the Commencement Date of the term of this Lease, and
continuing throughout the term of this Lease, Lessee shall pay to Lessor the
applicable monthly fixed rental, in advance, on the first day of each calendar
month of the term hereof. Payments under this Paragraph 4.1 for any period
during the te~ll1 of this Lease which is for less than one month shall be a pro
rata portion of the monthly fixed rental based on a 30 day month. In the event
the TRW Warehouse Space is not part of the Premises for all or a portion of the
Lease term, the payments of Rent required under this Lease shall be adjusted and
prorated accordingly.


<PAGE>

                    (c) The monthly fixed rental for each month during the term
of this Lease for the Premises shall be Nineteen Thousand Nine Hundred twelve
and 80/lOOths Dollars ($19,912.80) ($18,586.80 being allocated to the Primary
Premises and $1,326.00 to the TRW Warehouse Space).

                    (d) Anything in the Lease to the contrary notwithstanding,
Lessee shall not be obligated to pay monthly fixed rental for a four (4) month
period commencing with the Commencement Date, but Lessee shall be obligated to
pay Lessee's Share of Operating Expenses for such four (4) month period. In the
event Lessor is unable to make the TRW Warehouse Space available for occupancy
by Lessor until after the Commencement Date, Lessee shall have a separate four
(4) month rent abatement period as to the minimum monthly rent attributable to
the TRW Warehouse space, but shall pay Lessee's Share of Operating Expenses
attributable to the TRW Warehouse Space from the date Lessor makes the space
available to Lessee for occupancy.

                    (e) Lessee shall pay to Lessor upon delivery of the Premises
to Lessee the sum of $52,160.48 as prepaid rent which shall constitute the
monthly fixed rental and Lessee's Share of Operating Expenses (estimated at
(;6,167.44 per month) for the first two months following the four (4) month
period described in subparagraph (d) immediately above.

                    (f) In the event a Late Charge becomes payable pursuant to
Section 14.3 of the Lease for two (2) installments of Rent within a twelve (12)
month period, then all subsequent Rent payments shall immediately and
automatically become payable by Lessee quarterly in advance instead of monthly.

                    (g) Providing that (i) no uncured default then exist under
this Lease and (ii) no condition exists which but for the passage of time or the
giving of notice would constitute a default under this Lease, at the end of the
eighteenth (18) month of the Lease term Lessor shall deliver to Lessee Lessor's
check in the amount of Twenty-Five Thousand Dollars ($25,000) payable to Lessee
which shall represent a tenant allowance.

which 36.64% is allocated to the Primary Premises and 2.61% is allocated to the
TRW Warehouse Space). Lessee acknowledges that the Building is part of a
multi-building Building Project and that the Operating Expenses attributable to
the Building (and therefore Lessee's Share) include an allocation of a certain
portion of Operating Expenses relating to the total Building Project.

                    (c) The inclusion of the improvements, facilities and
services set forth in Paragraph 4.2(b)(i) of the definition of Operating

said improvements or facilities or to provide those services unless the Building
Project already has the same, Lessor already provides the services, or Lessor
has agreed elsewhere in this Lease to provide the same or some of them.
<PAGE>

                    (d) Operating Expenses shall not include any expenses paid
by any lessee directly to third parties.

                    (e) Lessee's Share of Operating Expenses shall be payable by
Lessee within ten (10) days after a reasonably detailed statement of actual
expenses is presented to Lessee by Lessor. At Lessor's option, however, an
amount may be estimated by Lessor from time to time of Lessee's Share of annual
Operating Expenses and the same shall be payable monthly or quarterly, as Lessor
shall designate, during each calendar year of the Lease term, on the same day as
the monthly fixed rental is due hereunder. In the event that Lessee pays
Lessor's estimate of Lessee's Share Of Operating Expenses, Lessor shall deliver
to Lessee within sixty (60) days after the expiration of each calendar year a
reasonably detailed statement showing Lessee's Share of the actual Operating
Expenses incurred during the preceding year. If Lessee's payments under this
Paragraph 4.2(e) during said preceding calendar year exceed Lessee's Share as
indicated on said statement, Lessee shall be entitled to credit the amount of
such overpayment against Lessee's Share of Operating Expenses next falling due.
If Lessee's payments under this paragraph during said preceding calendar year
were less than Lessee's Share as indicated on said statement, Lessee shall pay
to Lessor the amount of the deficiency within ten (10) days after delivery by
Lessor to Lessee of said statement.

               4.3 PAYMENT. Rent and all other charges payable to Lessor shall
be payable in lawful money of the United States to Lessor c/o CB Commercial Real

               4.4 REAL PROPERTY TAXES. Lessor shall pay the Real Property Tax,
as defined in paragraph 4.4 (a), applicable to the Building Project subject to
reimbursement by Lessee of Lessee's Share of such taxes in accordance with the
provisions of paragraph 4.2(a) and (b)(iv).

                    (a) As used herein, the term "Real Property Tax" shall
include any form of real estate tax or assessment, general, special, ordinary or
extraordinary, and any license fee, commercial rental tax, improvement bond or

imposed on the Building Project or any portion thereof by any authority having
the direct or indirect power to tax, including any city, county, state or
federal government, or any school, agricultural, sanitary, fire, street,
drainage or other improvement district thereof, as against any legal or
equitable interest of Lessor in the Building Project or in the real property of
which the Building Project is a part, as against Lessor's right to rent or other
income therefrom and against Lessor's business of leasing the Building Project.
The term "Real Property Tax" shall also include any tax, fee, levy assessment or
charge (i) in substitution of, partially or totally, any tax, fee, levy,
assessment or charge hereinabove included within the definition of "Real
Property Tax", or (ii) the nature of which was hereinbefore included within the
definition of "Real Property Tax,. or (iii) which is imposed as a result of a
transfer, either partial or


<PAGE>

total, of Lessor's interest in the Building Project or the Land or capital
improvement made thereto or which is added to a tax or charge hereinbefore
included within the definition of real property tax by reason of such
transfer or capital improvement, or (iv) which is imposed by reason of this
transaction, any modifications or changes hereto, or any transfers hereof. To
the extent any tax is imposed on the rents collected by Lessor from the
Premises, Building or Building Project, Lessee shall only be obligated to pay
such tax to the extent it is in lieu of ad valorem real property taxes as
presently assessed and collected in Los Angeles County, California.

                    (b) Lessee shall pay prior to delinquency all taxes assessed
against and levied upon trade fixtures, furnishings, equipment and all other
personal property of Lessee contained in the Premises or elsewhere. If any of
Lessee's said personal property shall be assessed with Lessor's real property,
Lessee shall pay to Lessor the taxes attributable to Lessee's personal property
within ten (10) days after receipt of a written statement setting forth the
taxes applicable to Lessee's personal property.

               4.5 UTILITIES.

                    (a) Lessee shall pay for all water, gas, heat, light, power,
telephone and other utilities and services specially or exclusively supplied
and/or metered exclusively to the Premises or to Lessee, together with any taxes
thereon. If any such services are not separately metered to the Premises, Lessee
shall pay at Lessor's option, either Lessee's Share or a reasonable proportion
to be determined by Lessor of all charges jointly metered with other premises in
the Building.

                    (b) There shall be no abatement of Rent and Lessor shall not
be liable in any respect whatsoever for the inadequacy, stoppage, interruption
or discontinuance of any utility or service due to riot, strike, labor dispute,
breakdown, accident, repair or other cause, except as expressly provided for in
Paragraph 4.6.

               4.6 TRIPLE NET LEASE. This Lease is what is commonly called a
"Net, Net, Net Lease," it being understood that Lessor shall receive the rent
set forth in Paragraph 4.1 free and clear of any and all other impositions,
taxes, liens, fees, charges or expenses of any nature whatsoever in connection
with the ownership and operation of the Premises. Nothing contained herein shall
require Lessee to pay any income, franchise, estate, succession, inheritance or
transfer taxes of Lessor pursuant to this Section 4. It is the intention of the
parties hereto that this Lease shall not be terminable for any reason by Lessee,
and that Lessee shall in no event be entitled to any abatement of or reduction
in Rent or any other charge payable under this Lease, except as expressly
provided in Paragraph 4.1 (d) above and Paragraphs 10.1, 10.2, and 15.2 below.
Any present or future law to the contrary shall not alter this agreement of the
parties.

          5. SECURITY DEPOSIT. Concurrently with the execution hereof, Lessee
shall deposit with Lessor the sum of $26,080.24 The funds deposited under this
Section 5 (the "Deposit") shall be non-interest bearing and held by Lessor as
security for the full and


<PAGE>

faithful performance of Lessee's covenants and obligations under this Lease,
it being understood and agreed that the Deposit is not an advance rental
deposit or a measure of Lessor's damages in case of Lessee's default. In the
event of a material breach (as defined in Section 14 of the Lease) by Lessee,
Lessor may, from time to time, without prejudice to any other remedy provided
herein or by Law, use the Deposit to the extent necessary to make good any
arrears of sums payable by Lessee hereunder, and any other damage, injury,
expense or liability caused by such default; Lessee shall pay to Lessor on
demand (but not more frequently than monthly) any amount necessary to restore
the Deposit to its original amount. Although the Deposit shall be deemed
property of the Lessor, any remaining balance of the Deposit shall be
returned to Lessee at such time after termination of this Lease that all of
Lessee's obligations under this Lease have been fulfilled.

no cost or expense whatsoever-to Lessor, promptly comply, or cause compliance,
with all laws, ordinances, zoning, zoning variances, orders, rules, regulations
and requirements of all federal, state, county, township and municipal
governments and all departments, commissions, boards and officers thereof,
whether present or future, foreseen or unforeseen, ordinary or extraordinary,
and whether or not the same shall be presently within the contemplation of
Lessor and Lessee or shall involve any change of governmental policy, or require
alterations or additions, and irrespective of the cost thereof, which may be
applicable to the Premises. Lessee shall also comply throughout the term of this
Lease, at its own cost and expense, with any requirement of all governmental
authorities having jurisdiction. Notwithstanding the foregoing, compliance with
ADA shall be in accordance with the provisions of Paragraph 3.2 (a) above.

                    (b) Except to the extent Lessor receives insurance proceeds
from any policy of insurance maintained pursuant to this Lease insuring Lessor
against any Loss (as hereinafter defined) incurred by Lessee and caused as
hereinafter described, no abatement, diminution or reduction in Rent, or any
other charges required to be paid by Lessee pursuant hereto, shall be claimed by
or allowed to Lessee for any inconvenience or interruption, cessation or loss of
business (collectively "Loss") caused, directly or indirectly, by any present or
future laws, ordinances, rules, regulations, requirements or orders of the
federal, state, county, township or municipal governments or any other lawful
authority whatsoever, or by priorities, rationing, or curtailment of labor or
materials, or by war, civil commotion, strikes or riots, or utility interruption

or causes, nor shall this Lease be affected by any such causes; and no
diminution in the amount of the space used by Lessee caused by legally required
changes in the construction, equipment,


<PAGE>

fixtures, motors, machinery, operation or use of the Building or parking
areas shall entitle Lessee to any abatement, diminution or reduction of the
Rent or any other charges required to be paid by Lessee pursuant to the terms
of this Lease except to the extent Lessor receives insurance proceeds from
any policy of insurance maintained pursuant to this Lease to compensate
Lessor for such diminution in the space used by Lessee.

               6.3 CONDITION OF TITLE. Lessee accepts this Lease and all right,
title and interest of Lessee hereunder subject to all easements, covenants,
conditions, restrictions, exceptions, zoning, zoning variances, reservations,
encumbrances and other matters affecting title to the Premises, including
without limitation, that certain Declaration of Covenants, Conditions and
Restrictions recorded on June 5, 1985 as Instrument No. 85-628623 in the
Official Records of Los Angeles County, California attached hereto as Exhibit
"C" and made a part hereof (the "Covenant, Conditions, and Restrictions").
Further, Lessee agrees to execute such appropriate documents subordinating its
interest in this Lease to easements for ingress and egress, for utilities and
for other purposes, which easements shall be necessary and appropriate for the
orderly development of the Premises and adjoining parcels.

          7. LESSEE'S CONSTRUCTION OF TENANT IMPROVEMENTS. Subject to the
provisions of Paragraph 3.2 above and in accordance with the provisions of 8.4
below, Lessee, at Lessee's sole cost and expense, shall construct any and all
improvements Lessee determines are necessary and/or appropriate for Lessee's
initial occupancy of the Premises. Such improvements as Lessee constructs in
connection with its initial occupancy of the Premises shall be hereinafter
collectively referred to as the "Tenant Improvements."

          8. MAINTENANCE. REPAIRS AND ALTERATIONS.

               8.1 LESSEE'S OBLIGATIONS.

                    (a) Lessee shall, at Lessee's sole cost and expense, keep
the Premises, including all HVAC, plumbing, electrical and mechanical systems
servicing the Premises, in good and sanitary condition and repair at all times
during the Term. All damage, injury or breakage to any part or portion of the
Premises or the Building Project caused by the willful or negligent act or
omission of Lessee or Lessee's agents, contractors, licensees, directors,
officers, partners, trustees, visitors or invitees (collectively, "Lessee's
Employees") shall be promptly repaired by Lessee, at Lessee's sole cost and
expense, to the satisfaction of Lessor provided, however, no such repair shall
be made without obtaining Lessor's prior written consent and instructions as to
any special precautions or steps which may be required; provided further,
however, that Lessee shall be entitled to receive reimbursement for such expense
to the extent that the cost of any such repair is covered by insurance obtained
by Lessor as part of Operating Expenses and is related to damage to the Premises
or to the Building Project rather than expenses. Lessor may make any repairs
which are not made by Lessee within a reasonable amount of time (except in the
case of emergency when such repairs can be made immediately), and charge Lessee
for the cost of such repairs. Lessee shall be solely


<PAGE>

responsible for the design and function of all Alterations (as hereinafter
defined) whether or not installed by Lessor at Lessee's request. Lessee
waives all rights to make repairs to the Premises or to the Building Project
at the expense of Lessor, or to deduct the cost of such repairs from any
payment owed to Lessor under the Lease.

                    (b) Lessee shall not make any claim or demand upon or bring
any action against Lessor for any loss, cost, liability, damages or other
expenses caused by any failure or defect, structural or nonstructural, of the
Premises or any part thereof. Without limiting the generality of the foregoing,
Lessee waives any right to make repairs at Lessor's expense under the provisions
of Sections 1941 and 1942 of the California Civil Code, as amended.

               8.2 SURRENDER. On the last day of the term hereof, or on any
earlier termination, Lessee shall surrender the Premises to Lessor in the same
condition as when received, broom clean, ordinary wear and tear excepted. Upon
surrender of the Premises Lessee shall have the right to remove Lessee's trade
fixtures, furnishings and equipment and Lessee shall repair any damage to the
Premises occasioned by the removal of the same, and the removal, pursuant to
Paragraph 8.4, of any Alterations (as hereinafter defined) made by Lessee, which
repairs shall include the patching, filling, painting of holes and repair of
structural damage.

               8.3 LESSOR'S RIGHTS. If Lessee fails to perform Lessee's
obligations under this Section 8, Lessor or Lessor's agents may (but shall not
be required to), at Lessor's option, enter upon the Premises, after ten (10)
days prior written notice to Lessee, and put the same in good order, condition
and repair. Lessee shall pay to Lessor, upon written demand therefor, all sums
necessary for Lessor to effectuate such work.

               8.4 ALTERATIONS AND ADDITIONS.

                    (a) Lessee shall not, without Lessor's prior written
consent, make any alterations, improvements, additions, or Utility Installation
(as defined below) in, on or about the Premises, without Lessor's prior written
consent which consent shall not be unreasonably withheld. Such alterations,
improvements, additions (including, without limitation, Tenant Improvements) or
Utility Installation (as defined below) constructed and/or installed by Lessee
in, on or about the Premises shall be collectively referred to as "Alterations."
Lessee shall first obtain Lessor's approval of the plans and specifications for
the Alterations. Lessee shall not make any change or alteration in connection
with any Alterations or otherwise to the exterior of the Premises or which could
possibly have an adverse effect on the Building's plumbing, heating, mechanical,
life safety, ventilation, air conditioning, electrical or security systems,
which could affect the structural integrity of the Building, or which could
affect the exterior appearance of the Building without Lessor's prior written
consent whether as a part of any Alterations or otherwise, which consent may be
withheld in Lessor's good faith discretion. As used in this Paragraph 8.4, the
term "Utility Installation" shall include carpeting, window coverings, air
lines, power panels, electrical distribution systems, lighting fixtures, space
heaters, air conditioning, plumbing, and fencing. Lessor may require that Lessee
remove
<PAGE>

any or all of said Alterations made with Lessor's consent forthwith following
the expiration of the term or other termination of this Lease, and restore
the Premises to their prior condition. Lessor may require Lessee to provide
Lessor, at Lessee's sole cost and expense, worker's compensation insurance, a
performance and payment bond in an amount equal to one and one-half times the
estimated cost of such improvements, to insure Lessor against any liability
for mechanic's and materialmen's liens and to insure completion of the work.
Should Lessee make any Alterations without the prior approval of Lessor,
Lessor may require that Lessee remove any or all of the same within thirty
(30) days after Lessor's notification. Lessee shall not be required to obtain
Lessor's approval of the plans and specifications for the Tenant Improvements
to be constructed by Lessee pursuant to Section 7 above providing the cost of
the Tenant Improvements does not exceed $10,000.00 in the aggregate providing
such Tenant Improvements are otherwise constructed in accordance with this
Paragraph 8.4.

                    (b) Any Alterations in, or about the Premises that Lessee
shall desire to make and which requires the consent of the Lessor shall be
presented to Lessor in written form, with proposed detailed plans. If Lessor
shall give its consent, the consent shall be deemed conditioned upon Lessee
obtaining a permit to do such work from all required governmental agencies, the
furnishing of a copy thereof to Lessor prior to the commencement of the work and
the compliance by Lessee of all conditions of said permit in a prompt and
expeditious manner.

                    (c) Unless Lessor requires their removal, as set forth in
Paragraph 8.4(a), all Alterations, including, without limitation, Utility
Installations which may constitute trade fixtures of Lessee, which may be made
on the Premises, shall become the property of Lessor and remain upon and be
surrendered with the Premises at the expiration of the term. Notwithstanding the
provisions of this Subparagraph 8.4(c), Lessee's trade fixtures, machinery and
equipment, other than that which is affixed to the Premises so that it cannot be
removed without material damage to the Premises, shall remain the property of
Lessee and may be removed by Lessee subject to the provisions of Paragraph 8.2.

                    (d) Lessee covenants and agrees to give Lessor written
notice of the commencement of any construction, alteration, addition,
improvements or repair, which notice shall be given to Lessor within ten (10)
days after the commencement of any such work, in order that Lessor may post
appropriate notices of Lessor's nonresponsibility.

                    (e) In the event the Premises are cited by any governmental
authority having jurisdiction in such matters as a consequence of the Premises
not being in compliance with the applicable provisions of the Americans With
Disabilities Act ("ADA") and such citation is received as a consequence of
Lessee constructing and/or installing Alterations to the Premises (either
pursuant to Paragraph 7 or 8.4 or otherwise) Lessee, at its expense, shall make
such modifications to the Premises as are required in order to comply with ADA
or otherwise cause the citation or order to be rescinded or waived.


<PAGE>

               8.5 LESSOR'S MAINTENANCE.

                    (a) SCOPE OF LESSOR'S REPAIRS. So long as no default (as
defined in Section 14 of this Lease) has occurred, which remains uncured, Lessor
shall maintain and repair the structural elements and the public and Common Area
of the Building as the same may exist from time to time, except for non-insured
damage or wear and tear which is the result of a negligent or willful act or
omission of Lessee or Lessee's Employees (as defined in Paragraph 8.1(a) of the
Lease). Lessor shall have no obligation to make repairs under this Section 8
until a reasonable time after receipt of written notice of the need for such
repairs. In no event shall any payments owed by Lessee under the Lease be
abated, nor shall Lessor have any liability for interruption or interference in
Lessee's business, on account of Lessor's failure to make repairs under this
Section 8. In addition and notwithstanding the provisions of Paragraph 8.1 (a),
Lessor shall at its sole cost and expense, keep the HVAC, roof and plumbing
systems servicing the Premises, in good and sanitary condition and repair during
the first six (6) months of the Term.

                    (b) LESSOR'S RIGHT OF ENTRY TO MAKE REPAIRS. Lessor and
Lessor's Employees (as defined in Paragraph 9.1 of the Lease) shall have the
right to enter the Premises at all reasonable times for the purpose of making
any alterations, additions, improvements or repairs to the Premises or the
Building as Lessor may deem necessary or desirable, without liability to Lessee.
Lessor shall give reasonable notice to Lessee of Lessor's intent to enter the
Premises and effect repairs, except, however, in an emergency situation, in
which case no prior notice shall be required.

          9. INSURANCE AND INDEMNITY.

               9.1 INDEMNIFICATION. Lessee shall at its expense defend,
indemnify, and hold Lessor and Lessor's agents, contractors, licensees,
employees, directors, officers, partners, trustees and invitees (collectively
"Lessor's Employees") harmless from and against any and all claims, arising out
of or in connection with Lessee's use of the Premises or the Building Project,
the conduct of Lessee's business, any activity, work or things done, permitted
or allowed by Lessee in or about the Premises or the Building Project, Lessee's
or Lessee's Employees' nonobservance or nonperformance of any statute, law,
ordinance, rule or regulation, or any negligence or willful act or failure to
act of Lessee or Lessee's Employees.

shall have been furnished to Lessee) are named as additional insureds and under
which the insurer agrees to indemnify and hold the Lessor, its managing agent
and all applicable lessors and mortgagees harmless from

and against all cost, expense and/or liability arising out of or based upon
the indemnification obligations of this Lease. The minimum limits of

either Lessor or Lessee in connection with any damage covered by any policy.
Neither Lessor nor Lessee shall be liable to the other for any damage caused by
fire or any of the risks insured against under any insurance policy required by

insurance cannot be obtained or the party in whose favor a waiver of

other party is relieved of the obligation to obtain a waiver of subrogation

and effect but the Rent shall be proportionately reduced as provided in
Paragraph 10.1(a). If Lessor does not elect by notice to Lessee to repair such
damage, or if the damage cannot, in Lessor's judgment, be commenced and so

affect Lessor's title to or rights thereto.

               11.3 CONTEST. Lessee shall have the right to contest any
mechanic's lien or other lien claim filed against the Premises, provided that

          13. ASSIGNMENT AND SUBLETTING.

               13.1 RIGHT TO ASSIGN AND SUBLEASE. Lessor and Lessee recognize
and specifically agree that this Section 13 is an economic provision, like Rent,
and that the Lessor's right to recapture, and to share in profits, is granted by
Lessee to Lessor in consideration of certain other economic concessions granted
by Lessor to Lessee. Lessee may voluntarily assign its interest in this Lease or
in the Premises, or sublease all or any part of the Premises, or allow any other
person or entity to occupy or use all or any part of the Premises, upon first
obtaining Lessor's prior consent, but only if such assignment or sublease does
not conflict with or result in a breach of Paragraph 6.1 and if such proposed
assignee or Sublessee of Lessee's proposed assignment or sublease is not:

                    (a) a governmental entity unless the identity of the
proposed governmenta1 entity is first approved by Lessor which approval may be
denied at Lessor's absolute discretion as a consequence of Lessor's prior
experience with or knowledge of such entity or similar or related entities;

                    (b) a person with whom Lessor has negotiated with for space
in the Building during the six (6) month period ending with the date Lessor
receives notice of such assignment, encumbrance or subletting;

                    (c) a present Lessee in the Building with whom Lessor has
negotiated with for space in the Building during the six (6) month period ending
with the date Lessor receives notice of such assignment, encumbrance or
subletting;

                    (d) a person or business entity whose tenancy in the
Building would violate any exclusivity arrangement which Lessor has with any
other tenant; or

                    (e) a person whose tenancy results in significantly more
people working at, or visiting, the Premises, than the number of people who
worked at, or visited, the Premises at the time when Lessee was the sole
occupant of the Premises. Any assignment, encumbrance or sublease without
Lessor's prior consent shall be voidable, at Lessor's election, and shall
constitute a default. No consent to an assignment, encumbrance or sublease shall
constitute a further waiver of the provisions of this Section 13.
<PAGE>

               13.2 PROCEDURE FOR ASSIGNMENT AND SUBLEASE /LESSOR'S RECAPTURE
RIGHTS. Lessee shall advise Lessor by notice of (a) Lessee's intent to assign,
encumber, or sublease this Lease, (b) the name of the proposed assignee or
sublessee, and evidence reasonably satisfactory to Lessor that such proposed
assignee or sublessee is comparable in reputation, stature and financial
condition to the other tenants then leasing comparable space in the Building,
and (c) the terms of the proposed assignment or subletting. Lessor shall, within
thirty (30) days of the later of receipt of such notice and receipt of any
additional information requested by Lessor concerning the proposed assignee's or
sublessee's financial responsibility, elect one of the following:

                         (i) Acknowledge that it does not object to such
proposed assignment, encumbrance or sublease;

                         (ii) Object to such proposed assignment, encumbrance or
sublease, which objection shall be on reasonable grounds; or

                         (iii) Elect to terminate the Lease in the event of an
assignment, or in the case of a sublease, terminate this Lease as to the portion
of the Premises proposed to be sublet for the proposed term of the sublease.

               13.3 CONDITIONS REGARDING CONSENT TO SUBLEASE AND ASSIGNMENT. As
a condition for Lessor not objecting to any assignment, encumbrance or sublease,
Lessee must require that the rent payable by such assignee or sublessee is at
least at the then current rental rates for the Premises or comparable Premises
in the Building, and, if Lessor so requests, shall require that the assignee or
sublessee remit directly to Lessor on a monthly basis, all rent due to Lessee by
said assignee or sublessee. In the event that Lessor does not object to an
assignment or sublease under the provisions of this Section 13, Lessee shall pay
Lessor's processing costs and attorneys' fees incurred in Lessor agreeing not to
object. Notwithstanding any permitted assignment or subletting, Lessee shall at
all times remain directly, primarily and fully responsible and liable for all
payments owed by Lessee under the Lease and for compliance with all obligations
under the terms, provisions and covenants of the Lease. If for any proposed
assignment or sublease, Lessee receives rent or other consideration, either
initially or over the term of the assignment or sublease, in excess of the Rent
required by this Lease, or, in the case of the sublease of a portion of the
Premises, in excess of such rent fairly allocable to such portion, after
appropriate adjustments to assure that all other payments called for hereunder
are taken into account, Lessee shall pay to Lessor as additional rent, one
hundred percent (100%) of the excess of each such payment of rent or other
consideration received by Lessee within five (5) days of its receipt.

               13.4 AFFILIATED COMPANIES /RESTRUCTURING OF BUSINESS
ORGANIZATION. Occupancy of all or part of the Premises by parent, subsidiary, or
affiliated companies of Lessee shall not be deemed an assignment or subletting
provided that such parent, subsidiary or affiliated companies were not formed as
a subterfuge to avoid the obligation of Section 13. If Lessee is a corporation,
unincorporated association, trust or general or
<PAGE>

limited partnership, then the sale, assignment, transfer or hypothecation of
any shares, partnership interest, or other ownership interest of such entity
which from time to time in the aggregate exceeds twenty-five percent (25%) of
the total outstanding shares, partnership interests or ownership interest of
such entity or which effects a change in the management or control of Lessee,
or the dissolution, merger, consolidation, or other reorganization of such
entity, or the sale, assignment, transfer or hypothecation of more than forty
percent (40%) of the value of the assets of such entity, shall be deemed an
assignment subject to the provisions of this Section 1 3.

in addition to any notice required under Section 1161 of the California Code of
Civil Procedure.

                    (b) The failure by Lessee to observe or perform any of the
non-monetary covenants, conditions or provisions of this Lease to be observed or
performed by Lessee, or of the Covenants, Conditions and Restrictions discussed
in Paragraph 6.3, other than as described in Subparagraph 14.1(a), where: if a
time for performance is expressly provided, and such failure shall exist after
the time expressly provided; or if there is no express time provision, and such
failure shall continue for a period of thirty (30) days after written notice of
the failure from Lessor to Lessee; provided, however, that if the default is
capable of being cured, but is not capable of being cured within said thirty
(30) day period, Lessee shall not be deemed to be in default if such cure is
commenced within said thirty (30) day period and Lessee diligently pursues the
cure to completion. Such thirty (30) day notice shall be in lieu of and not in
addition to any notice required under Section 1161 of the California Code of
Civil Procedure.

                    (c) The vacation or abandonment of the Premises by Lessee.

                    (d) The making by Lessee of any general assignment, or
general arrangement for the benefit of creditors; the filing by or against

substantially all of Lessee's assets located at the Premises or of Lessee's
interest in this Lease, where possession is not restored to Lessee within thirty

<PAGE>

substantially all of Lessee's assets located at the Premises or of Lessee's
interest in this Lease, where such seizure is not discharged within thirty (30)
days.

                    (e) The discovery by Lessor that any financial statement
given to Lessor by Lessee, any assignee of Lessee, any subtenant of Lessee, or
any successor in interest of Lessee, and any of them, was materially false when
delivered to Lessor.

               14.2 REMEDIES.

                    (a) In the event of any default by Lessee, the Lessor shall
have the right, in addition to all other rights available to Lessor under this
Lease or now or later permitted by law or equity, to terminate this Lease by
providing Lessee with a notice of termination. Upon termination, Lessor may
recover any damages proximately caused by Lessee's failure to perform under the
Lease, or which are likely in the ordinary course of business to be incurred,
including any amount expended or to be expended by Lessor in an effort to
mitigate damages, as well as any other damages to which Lessor is entitled to
recover under any statute now or later in effect. Lessor's damages include the
worth, at the time of any award, of the amount by which the unpaid Rent for the
balance of the term after the time of the award exceeds the amount of the rental
loss that the Lessee proves could be reasonably avoided. The worth at the time
of award shall be determined by discounting to present value such amount at one
percent (1%) more than the discount rate of the Federal Reserve Bank in San
Francisco in effect at the time of the award. Other damages to which Lessor is
entitled shall bear interest at the rate of ten percent (10%) per annum.

                    (b) In accordance with California Civil Code Section 1951.4
(or any successor statute), Lessee acknowledges that in the event Lessee has
breached this Lease and abandoned the Premises, this Lease shall continue in
effect for so long as Lessor does not terminate Lessee's right to possession,
and Lessor may enforce all its rights and remedies under this Lease, including
the right to recover the rent as it becomes due under this Lease. Acts of
maintenance or preservation or efforts to re-let the Premises or the appointment
of a receiver upon initiative of Lessor to protect Lessor's interest under this
Lease shall not constitute a termination of Lessee's right to possession.

                IN ADDITION TO ITS OTHER RIGHTS UNDER THIS LEASE,
               LESSOR HAS THE REMEDY DESCRIBED IN CALIFORNIA CIVIL
               CODE SECTION 1951.4 (LESSOR MAY CONTINUE THE LEASE
               IN EFFECT AFTER LESSEE'S BREACH AND ABANDONMENT AND
               RECOVER RENT (AS DEFINED IN PARAGRAPH 4.1(a) AS IT
                BECOMES DUE, IF LESSEE HAS THE RIGHT TO SUBLET OR
                ASSIGN, SUBJECT ONLY TO REASONABLE LIMITATIONS).

                    (c) In the event of any default by Lessee, Lessor shall also
have the right, with or without terminating this Lease, to enter the Premises
and remove all persons and personal property from the Premises, such property
being removed and stored in a public warehouse or elsewhere at Lessee's sole
cost and expense. No removal
<PAGE>

by Lessor of any persons or property in the Premises shall constitute an
election to terminate this Lease. Such an election to terminate may only be
made by Lessor in writing, or decreed by a court of competent jurisdiction.
Lessor's right of entry shall include the right to remodel the Premises and
re-let the Premises. All reasonable costs incurred in such entry and
re-letting shall be paid by Lessee. Rents collected by Lessor from any other
tenant which occupies the Premises shall be offset against the amounts owed
to Lessor by Lessee. Lessee shall be responsible for any amounts not
recovered by Lessor from any other tenant. Any payments made by Lessee shall
be credited to the amounts owed by Lessee in the sole order and discretion of
Lessor, irrespective of any designation or request by Lessee. No entry by
Lessor shall prevent Lessor from later terminating the Lease by written
notice.

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

                    (e) If Lessee fails to perform any covenant or condition to
be performed by Lessee, Lessor may perform such covenant or condition at is
option, after notice to Lessee. All costs incurred by Lessor in so performing
shall immediately be reimbursed to Lessor by Lessee, together with interest at
the interest rate equal to ten percent (10%) per annum computed from the due
date. Any performance by Lessor of Lessee's obligations shall not waive or cure
such default. Lessor may perform Lessee's defaulted obligations at Lessee's sole
cost and expense without notice in the case of any emergency. All costs and
expenses incurred by Lessor, including reasonable attorneys' fees (whether or
not legal proceedings are instituted), in collecting Rent or enforcing the
obligations of Lessee under the Lease shall be paid by Lessee to Lessor upon
demand.

                    (f) The rights and remedies of Lessor set forth herein are
not exclusive, and Lessor may exercise any other right or remedy available to it
under this Lease, at law or in equity.

               14.3 LATE CHARGES. Lessee hereby acknowledges that late payment
by Lessee to Lessor under this Lease (including but not limited to the payments
due under Paragraphs 4.1 and 4.2), will cause Lessor to incur costs not
contemplated by this Lease, the exact amount of which will be extremely
difficult to ascertain. Such costs include, but are not 1imited to, processing
and accounting charges, and late charges which may be imposed on Lessor.
Accordingly, if any installment of Rent or any other sum due from Lessee under
this Lease shall not be received by Lessor or Lessor's designee within ten (10)
days from the date when such payment is due, Lessee shall pay to Lessor a late
charge equal to six percent (6%) of such overdue amount ("Late Charge"). The
parties hereby agree that such late charge represents a fair and reasonable
estimate of the costs Lessor will incur by reason of late payment by Lessee.
Acceptance of such late charge by Lessor shall in no event constitute a waiver
of Lessee's default with respect to such overdue amount, nor prevent Lessor from
exercising any of the other rights and remedies granted hereunder.
<PAGE>

               14.4 FAILURE OF LESSEE TO PAY CLAIMS. Should Lessee fail to pay
or discharge or cause to be paid and discharged, at the time or times called for
in this Lease, any claim, imposition, insurance premium or other lien or charge
required to be paid by Lessee under this Lease, or any claim for damages arising
out of the repair, maintenance or use of the Premises, or to satisfy any
judgment rendered on any contested lien or claim, then Lessor may, at its option
but only after ten (10) days written notice to Lessee, pay such claim,
imposition, insurance premium, lien, or other charge, or settle or discharge any
action therefor, or satisfy any judgment thereon. All costs, expenses, penalties
and other sums incurred or paid by Lessor in connection therewith shall be paid
to Lessor by Lessee upon demand together with interest thereon at the per annum
rate equal to the lesser of the prime lending rate (whether known as the
"reference rate" or otherwise) charged by Bank of America NT & SA, as that rate
shall vary, or the maximum rate allowed by applicable law from the date incurred
or paid by Lessor until repaid by Lessee, and any default in such repayment
shall constitute a material default and breach of the covenants and conditions
of this Lease. If Lessee desires in good faith to contest any such lien or
claim, and it so notified Lessor of its intention to do so and furnishes to
Lessor a surety bond in an amount equal to one and one-half the amount of such
contested lien or claim indemnifying Lessor against liability for same within
ten (10) days after such lien comes into existence or such claim is first made,
as the case may be, Lessee shall not be in default hereunder and Lessor shall
not satisfy such lien or claim until five days after the determination of the
validity thereof.

               14.5 WAIVER. Lessee further covenants and agrees that if Lessor
fails or neglects for any reason to take advantage of any of the terms hereof
providing for the termination of this Lease or for the termination or forfeiture
of the estate hereby demised, or if Lessor, having the right to declare this
Lease terminated or the estate hereby demised, terminated or forfeited, shall
fail to do so, any such failure or neglect of Lessor shall not be or be deemed
to be construed to be a waiver of any provision for the termination of this
Lease continuing to exist or for the termination or forfeiture of the estate
hereby demised subsequently arising, or as a waiver of any of the covenants,
terms or conditions of this Lease or of the prompt performance thereof by
Lessee. None of the covenants, terms or conditions of this Lease can be waived
except by the written consent of the party entitled to the benefits thereof.

          15. CONDEMNATION.

               15.1 PERMANENT TAKING - WHEN LEASE CAN BE TERMINATED. If the
whole of the Premises, or so much of the Premises as to render the balance
unusable by Lessee, shall be taken under the power of eminent domain, the Lease
shall automatically terminate as of the date of final judgment in such
condemnation, or as of the date possession is taken by the condemning authority,
whichever is earlier. A sale by Lessor under the threat of condemnation shall
constitute a "taking" for the purpose of this Section 15. No award for any
partial or entire taking shall be apportioned and Lessee assigns to Lessor any
award which may be made in such taking or condemnation, together with all rights
of Lessee to such award, including, without limitation, any award
<PAGE>

or compensation for the value of all or any part of the leasehold estate;
provided that nothing contained in this Section 15 shall be deemed to give
Lessor any interest in or to require Lessee to assign to Lessor any award
made to Lessee and Lessee may maintain a separate action for (a) the taking
of Lessee's personal property, or (b) interruption to or damage to Lessee's
business, or (c) Lessee's unamortized cost of the Alterations to the extent
paid for by Lessee. Furthermore, Lessee shall be entitled to recover from
Lessor any advance payments of Rent made by Lessee attributable to that
unelasped portion of the term of the Lease following such taking.

               15.2 PERMANENT TAKING - WHEN LEASE CANNOT BE TERMINATED. In the
event of a partial taking which does not result in a termination of the Lease
under Section 15.1, Rent shall proportionately be reduced based on the portion
of the Premises rendered unusable, and Lessor shall restore the Premises or the
Building to the extent of available condemnation proceeds.

               15.3 TEMPORARY TAKING. No temporary taking of the Premises or any
part of the Premises and/or of Lessee's rights to the Premises or under this
Lease shall terminate this Lease or give Lessee any right to any abatement of
any payments owed to Lessor pursuant to this Lease unless such taking would
substantially and adversely affect the operation and profitability of Lessee's
business conducted from the Premises; any award made to Lessee by reason of such
temporary taking shall belong entirely to Lessee. For the purposes of this
Lease, any taking, which at the time of such taking, is known to be for a period
less than six (6) months or any taking which in fact lasts less than six (6)
months shall be deemed a "temporary" taking and shall be governed by Paragraph
15.3. Any taking which, at the time of the taking, is known to be for a period
of six (6) months or longer or any taking which in fact lasts for a period of
six (6) months or longer shall be deemed a permanent taking and shall be
governed by Paragraphs 15.1 and 15.2.

               15.4 EXCLUSIVE REMEDY. This Section 15 shall be Lessee's sole and
exclusive remedy in the event of a taking or condemnation. Lessee hereby waives
the benefit of California Code of Civil Procedure Section 1265. 130.

               15.5 RELEASE UPON TERMINATION. Upon termination of the Lease
pursuant to this Section 15, Lessee and Lessor hereby agree to release each
other from any and all obligations and liabilities with respect to the Lease
except for such obligations and liabilities which arise or accrue prior to such
termination.

          16. ESTOPPEL CERTIFICATE.

               16.1 LESSEE'S CERTIFICATE. Lessee shall at any time, upon not
less than ten (10) days prior written notice from Lessor, execute, acknowledge
and deliver to Lessor, a statement in writing (i) certifying that this Lease is
unmodified and in full force and effect (or, if modified, stating the nature of
such modification and certifying that this Lease, as so modified, is in full
force and effect) and the date to which the Rent and other charges are paid in
advance, if any, and (ii) acknowledging that there are not to Lessee's
knowledge, any uncured defaults on the part of Lessor hereunder, or specifying
such
<PAGE>

defaults if any are claimed. Any such statement may be conclusively relied
upon by any prospective purchaser or encumbrancer of the Premises. Lessee's
failure to deliver such statement within such time shall be conclusive upon
Lessee (i) that this Lease is in full force and effect, without modification
except as may be represented by Lessor, (ii) that there are no uncured
defaults in Lessor's performance, and (iii) that not more than one month's
Rent has been paid in advance, Such failure to timely deliver such statement
may be considered by Lessor as a default by Lessee under this Lease.

               16.2 LESSOR'S CERTIFICATE. Lessor shall at any time, upon not
less than ten (10) days prior written notice from Lessee, execute, acknowledge
and deliver to Lessee a statement in writing (i) certifying that this Lease is
unmodified and in full force and effect (or, if modified, stating the nature of
such modification and certifying that this Lease, as so modified, is in full
force and effect) and the date to which the Rent and other charges are paid in
advance, if any, and (ii) acknowledging that there are not to Lessor's
knowledge, any uncured defaults on the part of Lessee hereunder, or specifying
such defaults, if any, are claimed.

               16.3 FINANCIAL STATEMENTS. If Lessor desires to finance or
refinance the Premises, or any part hereof, Lessee hereby agrees to deliver to
any lender designated by Lessor such financial statement of Lessee as may be
reasonably required by such lender. Such statements shall include Lessee's
financial statements for the three years preceding the then current year if
required by said lender. All such financial statements shall be used only for
the purposes herein set forth.

          17. LESSOR'S LIABILITY. In the event Lessor shall sell, assign, convey
or transfer all or a part of its interest in the Building Project or the Land or
any part thereof, Lessee agrees to attorn to such transferee, assignee or new
owner, and upon consummation of such sale, conveyance or transfer, Lessor shall
automatically be freed and relieved from all liability and obligations accruing
or to be performed from and after the date of such sale, transfer, or
conveyance. In the event of such sale, assignment, transfer or conveyance,
Lessor shall transfer to such transferee, assignee or new owner of the Building
Project or the Land the balance of the Deposit, if any, remaining after lawful
deductions and in accordance with California Civil Code Section 1950.7, after
notice to Tenant, and Landlord shall thereupon be relieved of all liability with
respect to the Deposit.

          18. SEVERABILITY. The invalidity, illegality or unenforceability of
any provisions of this Lease as determined by a court of competent jurisdiction,
shall in no way affect the validity of any other provision thereof.

          19. INTEREST ON PAST-DUE OBLIGATIONS. Except as expressly herein
provided, any amount due Lessor not paid when due shall, at Lessor's option,
bear interest at a per annum rate equal to the lesser of the Bank of America
prime lending rate (whether known as the "reference rate" or otherwise), as that
rate shall vary, or the maximum rate allowed by applicable law. Payment of such
interest shall, not excuse or cure any default by Lessee under this Lease.
<PAGE>

          20. TIME OF ESSENCE. Subject to the provisions of Section 48 hereof,
time is of the essence of the Lease and of each of the provisions hereof.

          21. CAPTIONS. The captions of the paragraphs and sections of this
Lease are for convenience only and shall not be considered or referred to in
resolving questions of interpretation or construction.

          22. INCORPORATION OF PRIOR AGREEMENTS AMENDMENTS. This Lease contains
all agreements of the parties with respect to any matter mentioned herein. No
prior agreement or understanding pertaining to any such matter shall be
effective. This Lease may be modified in writing only, signed by the parties in
interest at the time of modification. Except as otherwise stated in this Lease,
Lessee hereby acknowledges that neither the Broker(s) listed in Section 12
hereof, if any. nor Lessor nor any employees or agents of any of said persons
has made any oral or written warranties or representations to Lessee relating to
the condition or use by Lessee of the Premises.

address or addresses as either Lessee or Lessor may from time to time designate
to the other by written notice in accordance herewith.

          24. WAIVERS. No waiver by either party hereto of any provision hereof
shall be deemed a waiver of any other provision thereof or of any subsequent
breach by the other party of the same or any other provision. Lessor's or
Lessee's consent to or approval of any act by the other shall not be deemed to
render unnecessary the obtaining of subsequent consent to or approval of any
subsequent act. The acceptance of rent hereunder by Lessor shall not be a waiver
of any preceding breach by Lessee of any provision hereof other than the failure
of Lessee to pay the particular rent so accepted. Regardless of Lessor's
knowledge of such preceding breach at the time of acceptance of such rent. No
payment by Lessee or receipt by Lessor of a lesser amount than any rent payment
specified herein shall be deemed to be other than on account of rent, nor shall
any endorsement or statement on any check or any letter accompanying any check
or statement as rent be deemed an accord and satisfaction, and Lessor may accept
such check or payment without prejudice to Lessor's right to recover the balance
of rent or pursue any other remedy provided for in this Lease.

          25. RECORDING. Lessor and Lessee agree that in no event and under no
circumstances shall Lessee record this Lease.

          26. HOLDING OVER. If Lessee remains in possession of the Premises or
any part thereof after the expiration of the term hereof without the express
written consent of Lessor, such occupancy shall be a tenancy from month to month
with monthly rental payable by Lessee in the amount of 150% of the last monthly
fixed rental pursuant to Paragraph 4.1, plus all other charges payable hereunder
including, without limitation, Lessee's Share of Operating Expenses, and upon
all the terms hereof applicable to a month-to-month tenancy.

          27. CUMULATIVE REMEDIES. No remedy or election hereunder shall be
deemed exclusive but shall, wherever possible, be cumulative with all other
remedies at law or in equity.

          28. COVENANTS AND CONDITIONS. All of the provisions of the Lease shall
be deemed as running with the Land, and construed to be "conditions" as well as
"covenants" as though the words specifically expressing or imparting covenants
and conditions were used in each separate provision.
<PAGE>

          29. BINDING EFFECT. Subject to any provisions hereof restricting
assignment or subletting by Lessee and subject to the provisions of Section 17,
this Lease shall bind the parties, their personal representatives, successors or
assigns.

concerning this Lease and Lessee's use of the Premises shall be governed by, and
decided in accordance with, the laws of the State of California. Any litigation
or action with respect to, related to, or concerning this Lease and Lessee's use
of the Premises shall be conducted only in the California courts. Lessee agrees
to submit to the jurisdiction of the California courts in the event of any court
action with respect to, related to, or concerning this Lease and Lessee's use of
the Premises.

          31. ATTORNMENT. Lessee agrees, upon demand by Lessor, to attorn to any
purchaser at any foreclosure sale, or to any grantee or transferee designated in
any deed given in lieu of foreclosure. Lessee also agrees to cause any sublessee
or assignee of Lessee to attorn to Lessor or to any purchaser at any foreclosure
sale, or to any grantee or transferee designated in any deed given in lieu of
foreclosure.

          32. SUBORDINATION. Lessee agrees that in the event any mortgage or
deed of trust on the Land, Building Project or the Premises, or Lessee's
interest therein, or any part thereof, is executed by Lessor or any of Lessor's
successors or assigns in favor of any lender, this Lease shall automatically be
subordinate to the lien of any such mortgage or deed of trust, and to any
replacements, renewals or extensions thereof, and Lessee will, upon written
demand from Lessor, or the mortgagee under any such mortgage or the beneficiary
of any such deed of trust, subordinate this Lease to the lien of said mortgage
or deed of trust, and to any replacements, renewals or extensions thereof, and
upon receipt of such demand Lessee will promptly execute, acknowledge and
deliver any instruments, releases or other documents that may be required by
such mortgagee or beneficiary for the purpose of effecting such subordination.
In the event Lessee fails to execute any such document within fifteen (15) days
of a request to do so, Lessee hereby appoints Lessor and any such mortgagee or
beneficiary, severally and not jointly, the attorney-in-fact of Lessee to
execute and deliver such instruments, releases or other document for and on
behalf of Lessee. A mortgage or deed of trust to which this Lease shall be
subordinate shall include a provision to the effect that, notwithstanding such
subordination, the mortgagee agrees that so long as Lessee faithfully discharges
all obligations on its part to be kept and performed under this Lease, its
tenancy will not be affected by any default under such mortgage or deed of
trust, and in the event of foreclosure or sale under power of sale, the rights
of Lessee under this Lease shall survive and this Lease shall in all respects
continue in full force and effect provided that Lessee fully performs all of its
obligations thereunder.

          33. ATTORNEY'S FEES. If either Lessor or Lessee commences or engages
in an action, arbitration or other proceeding by or against the other party
arising out of or in connection with this Lease or the Premises, including but
not limited to any action for recovery of Rent due and unpaid, to recover
possession or for damages for breach of this Lease, the prevailing party shall
be entitled to have and recover from the losing party
<PAGE>

reasonable attorneys' fees and other costs incurred in the action,
arbitration or proceeding and in preparation for the same.

          37. AUTHORITY. Each individual executing this Lease on behalf of
Lessee or Lessor represents and warrants that he is duly authorized to execute
and deliver this Lease on behalf of Lessee or Lessor in accordance with a duly
adopted resolution of Lessee's or Lessor's Board of Directors or in accordance
with Lessee's or Lessor's Bylaws, and that this Lease is binding upon Lessee or
Lessor as the case may be in accordance with its terms. Lessee shall, within
thirty (30) days after execution of this Lease, deliver to Lessor a certified
copy of a resolution of its Board of Directors authorizing or ratifying the
execution of this Lease.

          38. CONSENTS. Except as specifically provided herein, wherever in this
Lease the consent of one party is required to an act of the other party, such
consent may be made subject to such reasonable conditions as the consenting
party deems appropriate. Except as otherwise provided herein and in emergency
situations, the consenting party shall have thirty (30) days from receipt of the
request for consent to respond thereto.

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

          40. ARBITRATION. If any controversy shall arise between the parties
with respect to any other matters set forth in this Lease and such dispute shall
not be resolved by the parties within thirty (30) days after either of the
parties shall notify the other of its desire to arbitrate the dispute, then the
dispute shall be settled by arbitration in accordance with the provisions of
Title 9 of the Code of Civil Procedure of California and judgment upon the award
rendered by the arbitrators may be entered in any court having jurisdiction. The
arbitration shall be by a panel of three (3) arbitrators, one of whom must be an
attorney at law actively engaged in the practice of his profession for at least
ten (10) years. The arbitrators shall have no power to modify any of the
provisions hereof and their jurisdiction is limited accordingly. Each party
hereby consents to the entry of judgment by any court having jurisdiction in
accordance with the decision of the arbitration panel. No change in the rules of
arbitration which would deprive a party of the right to be represented by
counsel, to present evidence, or to cross-examine witnesses presented by the
other party shall be effective in any arbitration proceeding arising out of this
agreement. Nothing contained in this Section 40 shall prevent any party from
exercising, in a court having jurisdiction thereof in lieu of arbitration, those
rights granted in Section 14 hereof.

          41. RESERVATION OF MINERALS. There is reserved to the Lessor the title
and exclusive right to all of the minerals and mineral ores of every kind and
character now known to exist or hereafter discovered upon, within or underlying
the Land, or that may be produced therefrom, including, without limiting the
generality of the foregoing, all petroleum, oil, natural gas and other
hydrocarbon substances and products derived
<PAGE>

therefrom and all geothermal steam or brines which may be produced or derived
therefrom, together with the exclusive and perpetual right thereto, without,
however, the right to use or penetrate the surface of, or to enter upon the
Land within five hundred (500) feet of the surface thereof, to extricate or
remove the same.

          42. COMPUTATION OF TIME. The time in which any act provided by this

attorneys fees, the actual incurrence of such items in a manner consistent with

litigation or other proceeding in connection with the Communications

manner within such fifteen (15) day period, Lessor may assume the defense, at
the expense of Lessee. The attorneys selected by Lessee for the defense of
