2.  Premises.

     2.1  Letting.  Lessor hereby leases to Lessee, and Lessee hereby leases
from Lessor, the Premises, for the term, at the rental, and upon all of the
terms, covenants and conditions set forth in this Lease.  Unless otherwise
provided herein, any statement of size set forth in this Lease, or that may have
been used in calculating rental, is an approximation which the Parties agree is
reasonable and the rental based thereon is not subject to revision whether or
not the actual size is more or less.

     2.2  Condition.  Lessor shall deliver the Premises to Lessee broom clean
and free of debris on the Commencement Date or Early Possession Date, whichever
first occurs ("Start Date"), and, so long as the required service contracts
described in Paragraph 7.1(b) below are obtained by Lessee within thirty (30)
days following the Start Date, warrants that the existing electrical, plumbing,
fire sprinkler, lighting, heating, ventilating and air conditioning systems
("HVAC"), loading doors, if any, and all other such elements in the Premises,
other than those constructed by Lessee, shall be in good operating condition on
said date and that the structural elements of the roof, bearing walls and
foundation of any buildings on the Premises (the "Building") shall be free of
material defects.  If a non-compliance with said warranty exists as of the State
Date, Lessor shall, as Lessor's sole obligation with respect to such matter,
except as otherwise provided in this Lease, promptly after receipt of written
notice from Lessee setting forth with specificity the nature and extent of such
non-compliance, rectify same at Lessor's expense.  If, after the Start Date,
Lessee does not give Lessor written notice of any non-compliance with this
warranty within:  (i) one year as to the surface of the roof and the structural
portions of the roof, foundations and bearing walls, (ii) six (6) months as to
the HVAC systems, (iii) thirty (30) days as to the remaining systems and other
elements of the Building, correction of such non-compliance shall be the
obligation of Lessee at Lessee's sole cost and expense.

                                       2
<PAGE>

     2.3  Compliance.  Lessor warrants that the improvements on the Premises
comply with all applicable laws, covenants or restrictions of record, building
codes, regulations and ordinances ("Applicable Requirements") in effect on the
Start Date.  Said warranty does not apply to the use to which Lessee will put
the Premises or to any Alterations or Utility Installations (as defined in
Paragraph 7.3(a)) made or to be made by Lessee.  NOTE:  Lessee is responsible
for determining whether or not the zoning is appropriate for Lessee's intended
use, and acknowledges that past uses of the Premises may no longer be allowed.
If the Premises do not comply with said warranty, Lessor shall, except as
otherwise provided promptly after receipt of written notice from Lessee setting
forth with specificity the nature and extent of such non-compliance, rectify the
same at Lessor's expense.  If Lessee does not give Lessor written notice of a
non-compliance with this warranty within six (6) months following the Start
Date, correction of that non-compliance shall be the obligation of Lessee at
Lessee's sole cost and expense.  If the Applicable Requirements are hereafter
changed (as opposed to being in existence at the Start Date, which is addressed
in Paragraph 6.2(e) below) so as to require during the term of this Lease the
construction of an addition to or an alteration of the Building, the remediation
of any Hazardous Substance, or the reinforcement or other physical modification
of the Building ("Capital Expenditure"), Lessor and Lessee shall allocate the
cost of such work as follows:

          (a) Subject to Paragraph 2.3(c) below, if such Capital Expenditures
are required as a result of the specific and unique use of the Premises by
Lessee as compared with uses by tenants in general, Lessee shall be fully
responsible for the cost thereof, provided, however that if such Capital
Expenditure is required during the last two (2) years of this Lease and the cost
thereof exceeds six (6) months' Base Rent, Lessee may instead terminate this
Lease unless Lessor notifies Lessee, in writing, within ten (10) days after
receipt of Lessee's termination notice that Lessor has elected to pay the
difference between the actual cost thereof and the amount equal to six (6)
months' Base Rent.  If Lessee elects termination, Lessee shall immediately cease
the use of the Premises which requires such Capital Expenditure and deliver to
Lessor written notice specifying a termination date at least ninety (90) days
thereafter.  Such termination date shall, however, in no event be earlier than
the last day that Lessee could legally utilize the Premises without commencing
such Capital Expenditure.

          (b) If such Capital Expenditure is not the result of the specific and
unique use of the Premises by Lessee (such as, governmentally mandated seismic
modifications), then Lessor and Lessee shall allocate the obligation to pay for
such costs pursuant to the provisions of Paragraph 7.1(c); provided, however,
that if such Capital Expenditure is required during the last two years of this
Lease or if Lessor reasonably determines that it is not economically feasible to
pay its share thereof, Lessor shall have the option to terminate this Lease upon
ninety (90) days prior written notice to Lessee unless Lessee notifies Lessor,
in writing, within ten (10) days after receipt of Lessor's termination notice
that Lessee will pay for such Capital Expenditure.  If Lessor does not elect to
terminate, and fails to tender its share of any such Capital Expenditure, Lessee
may advance such funds and deduct same, with Interest, from Rent until Lessor's
share of such costs have been fully paid.  If Lessee is unable to finance
Lessor's share, or if the balance of the Rent due and payable for the remainder
of this Lease is not sufficient to fully reimburse Lessee on an offset basis,
Lessee shall have the right to terminate this Lease upon thirty (30) days
written notice to Lessor.

                                       3
<PAGE>

          (c) Notwithstanding the above, the provisions concerning Capital
Expenditures are intended to apply only to non-voluntary, unexpected, and new
Applicable Requirements.  If the Capital Expenditures are instead triggered by
Lessee as a result of an actual or proposed change in use, change in intensity
of use, or modification to the Premises then, and in that event, Lessee shall be
fully responsible for the cost thereof, and Lessee shall not have any right to
terminate this Lease.

     2.4  Acknowledgements.  Lessee acknowledges that:  (a) it has been advised
by Lessor and/or Brokers to satisfy itself with respect to the condition of the
Premises (including but not limited to the electrical, HVAC and fire sprinkler
systems, security, environmental aspects, and compliance with Applicable
Requirements), and their suitability for Lessee's intended use, (b) Lessee has
made such investigation as it deems necessary with reference to such matters and
assumes all responsibility therefor as the same relate to its occupancy of the
Premises, and (c) neither Lessor, Lessor's agents, nor any Broker has made any
oral or written representations or warranties with respect to said matters other
than as set forth in this Lease.  In addition, Lessor acknowledges that:  (a)
Broker has made no representations, promises or warranties concerning Lessee's
ability to honor the Lease or suitability to occupy the Premises, and (b) it is
Lessor's sole responsibility to investigate the financial capability and/or
suitability of all proposed tenants.

3.   Term.

     3.1  Term.  The Commencement Date, Expiration Date and Original Term of
this Lease are as specified in Paragraph 1.3.

     3.2  Early Possession.  If Lessee totally or partially occupies the
Premises prior to the Commencement Date, the obligation to pay Base Rent shall
be abated for the period of such early possession.  All other terms of this
Lease (including but not limited to the obligations to pay Real Property Taxes
and insurance premiums and to maintain the Premises) shall, however, be in
effect during such period.  Any such early possession shall not affect the
Expiration Date.

     3.3  Delay In Possession.  Lessor agrees to use its best commercially
reasonable efforts to deliver possession of the Premises to Lessee by the
Commencement Date.  If, despite said efforts, Lessor is unable to deliver
possession as agreed, Lessor shall not be subject to any liability therefor, nor
shall such failure affect the validity of this Lease.  Lessee shall not,
however, be obligated to pay Rent or perform its other obligations until it
receives possession of the Premises.  If possession is not delivered within
sixty (60) days after the Commencement Date, Lessee may, at its option, by
notice in writing within ten (10) days after the end of such sixty (60) day
period, cancel this Lease, in which event the Parties shall be discharged from
all obligations hereunder.  If such written notice is not received by Lessor
within said ten (10) day period, Lessee's right to cancel shall terminate.
Except as otherwise provided, if possession is not tendered to Lessee by the
Start Date and Lessee does not terminate this Lease, as aforesaid,

                                       4
<PAGE>

any period of rent abatement that Lessee would otherwise have enjoyed shall run
from the date of delivery of possession and continue for a period equal to what
Lessee would otherwise have enjoyed under the terms hereof, but minus any days
of delay caused by the acts or omissions of Lessee. If possession of the
Premises is not delivered within four (4) months after the Commencement Date,
this Lease shall terminate unless other agreements are reached between Lessor
and Lessee, in writing.

     3.4  Lessee Compliance.  Lessor shall not be required to tender possession
of the Premises to Lessee until Lessee complies with this obligation to provide
evidence of insurance (Paragraph 8.5).  Pending deliver of such evidence, Lessee
shall be required to perform all of its obligations under this Lease from and
after the Start Date, including the payment of Rent, notwithstanding Lessor's
election to withhold possession pending receipt of such evidence of insurance.
Further, if Lessee is required to perform any other conditions prior to or
concurrent with the Start Date, the Start Date shall occur but Lessor may elect
to withhold possession until such conditions are satisfied.

4.   Rent.

     4.1  Rent Defined.  All monetary obligations of Lessee to Lessor under the
terms of this Lease (except for the Security Deposit) are deemed to be rent
("Rent").

     4.2  Payment.  Lessee shall cause payment of Rent to be received by Lessor
in lawful money of the United States, without offset or deduction (except as
specifically permitted in this Lease); on or before the day on which it is due.
Rent for any period during the term hereof which is for less than one (1) full
calendar month shall be prorated based upon the actual number of days of said
month.  Payment of Rent shall be made to Lessor at its address stated herein or
to such other persons or place as Lessor may from time to time designate in
writing.  Acceptance of a payment which is less than the amount then due shall
not be a waiver of Lessor's rights to the balance of such Rent, regardless of
Lessor's endorsement of any check so stating.

5.   Security Deposit.  Lessee shall deposit with Lessor upon execution hereof
the Security Deposit as security for Lessee's faithful performance of its
obligations under this Lease.  If Lessee fails to pay Rent, or otherwise
Defaults under this Lease, Lessor may use, apply or retain all or any portion of
said Security Deposit for the payment of any amount due Lessor or to reimburse
or compensate Lessor for any liability, expense, loss or damage which Lessor may
suffer or incur by reason thereof.  If Lessor uses or applies all or any portion
of said Security Deposit, Lessee shall within ten (10) days after written
request therefor deposit monies with Lessor sufficient to restore said Security
Deposit to the full amount required by this Lease.  If the Base Rent increases
during the term of this Lease, Lessee shall, upon written request from Lessor,
deposit additional moneys with Lessor so that the total amount of the Security
Deposit shall at all times bear the same proportion to the increased Base Rent
as the initial Security Deposit bore to the initial Base Rent.  Should the
Agreed Use be amended to accommodate a material change in the business of Lessee
or to accommodate a sublessee or assignee, Lessor shall have the right to
increase the Security Deposit to the extent necessary, in Lessor's reasonable
judgment, to account for any increased wear and tear that the Premises may
suffer as

                                       5
<PAGE>

a result thereof.  If a change in control of Lessee occurs during this
Lease and following such change the financial condition of Lessee is, in
Lessor's reasonable judgment, significantly reduced, Lessee shall deposit such
additional monies with Lessor as shall be sufficient to cause the Security
Deposit to be at a commercially reasonable level based on said change in
financial condition.  Lessor shall not be required to keep all or any part of
the Security Deposit separate from its general accounts.  Within fourteen (14)
days after the expiration or termination of this Lease, if Lessor elects to
apply the Security Deposit only to unpaid Rent, and otherwise within thirty (30)
days after the Premises have been vacated pursuant to Paragraph 7.4(c) below,
Lessor shall return that portion of the Security Deposit not used or applied by
Lessor.  No part of the Security Deposit shall be considered to be held in
trust, to bear interest or to be prepayment for any monies to be paid by Lessee
under this Lease.

6.   Use.

     6.1  Use.  Lessee shall use and occupy the Premises only for the Agreed
Use, or any other legal use which is reasonably comparable thereto, and for no
other purpose.  Lessee shall not use or permit the use of the Premises in a
manner that is unlawful, creates damage, waste or a nuisance, or that disturbs
owners and/or occupants of, or causes damage to neighboring properties.  Lessor
shall not unreasonably withhold or delay its consent to any written request for
a modification of the Agreed Use, so long as the same will not impair the
structural integrity of the improvements on the Premises or the mechanical or
electrical systems therein, is not significantly more burdensome to the
Premises.  If Lessor elects to withhold consent, Lessor shall within five (5)
business days after such request give a written notification of same, which
notice shall include an explanation of Lessor's objections to the change in use.

     6.2  Hazardous Substances.

          (a) Reportable Uses Require Consent.  The term "Hazardous Substance"
as used in this Lease shall mean any product, substance, or waste whose
presence, use, manufacture, disposal, transportation, or release, either by
itself or in combination with other materials expected to be on the Premises, is
either: (i) potentially injurious to the public health, safety or welfare, the
environment or the Premises, (ii) regulated or monitored by any governmental
authority, or (iii) a basis for potential liability of Lessor to any
governmental agency or third party under any applicable statute or common law
theory.  Hazardous Substances shall include, but not be limited to,
hydrocarbons, petroleum, gasoline, and/or crude oil or any products, by-products
or fractions thereof.  Lessee shall not engage in any activity in or on the
Premises which constitutes a Reportable Use of Hazardous Substances without the
express prior written consent of Lessor and timely compliance (at Lessee's
expense) with all Applicable Requirements.  "Reportable Use" shall mean (i) the
installation or use of any above or below ground storage tank, (ii) the
generation, possession, storage, use, transportation, or disposal of a Hazardous
Substance that requires a permit from, or with respect to which a report,
notice, registration or business plan is required to be filed with, any
governmental authority, and/or (iii) the presence at the Premises of a Hazardous
Substance with respect to which any Applicable Requirements requires that a
notice be given to persons entering or occupying the Premises or neighboring
properties.  Notwithstanding the foregoing, Lessee may use any ordinary and

                                       6
<PAGE>

customary materials reasonably required to be used in the normal course of the
Agreed Use, so long as such use is in compliance with all Applicable
Requirements, is not a Reportable Use, and does not expose the Premises or
neighboring property to any meaningful risk of contamination or damage or expose
Lessor to any liability therefor.  In addition, Lessor may condition its consent
to any Reportable Use upon receiving such additional assurances as Lessor
reasonably deems necessary to protect itself, the public, the Premises and/or
the environment against damage, contamination, injury and/or liability,
including, but not limited to, the installation (and removal on or before Lease
expiration or earlier termination) of protective modifications (such as concrete
encasements) and/or increasing the Security Deposit.

          (b) Duty to Inform Lessor.  If Lessee knows, or has reasonable cause
to believe, that a Hazardous Substance has come to be located in, on, under or
about the Premises, other than as previously consented to by Lessor, Lessee
shall immediately give written notice of such fact to Lessor, and provide Lessor
with a copy of any report, notice, claim or other documentation which it has
concerning the presence of such Hazardous Substance.

          (c) Lessee Remediation.  Lessee shall not cause or permit any
Hazardous Substance to be spilled or released in, on, under, or about the
Premises (including through the plumbing or sanitary sewer system) and shall
promptly, at Lessee's expense, take all investigatory and/or remedial action
reasonably recommended, whether or not formally ordered or required, for the
cleanup of any contamination of, and for the maintenance, security and/or
monitoring of the Premises or neighboring properties, that was caused or
materially contributed to by Lessee, or pertaining to or involving any Hazardous
Substance brought onto the Premises during the term of this Lease, by or for
Lessee, or any third party.

          (d) Lessee Indemnification.  Lessee shall indemnify, defend and hold
Lessor, its agents, employees, lenders and ground lessor, if any, harmless from
and against any and all loss of rents and/or damages, liabilities, judgments,
claims, expenses, penalties, and attorneys' and consultants' fees arising out of
or involving any Hazardous Substance brought onto the Premises by or for Lessee,
or any third party (provided, however, that Lessee shall have no liability under
this Lease with respect to underground migration of any Hazardous Substance
under the Premises from adjacent properties).  Lessee's obligations shall
include, but not be limited to, the effects of any contamination or injury to
person, property or the environment created or suffered by Lessee, and the cost
of investigation, removal, remediation, restoration and/or abatement, and shall
survive the expiration or termination of this Lease.  No termination,
cancellation or release agreement entered into by Lessor and Lessee shall
release Lessee from its obligations under this Lease with respect to Hazardous
Substances, unless specifically so agreed by Lessor in writing at the time of
such agreement.

          (e) Lessor Indemnification.  Lessor and its successors and assigns
shall indemnify, defend, reimburse and hold Lessee, its employees and lenders,
harmless from and against any and all environmental damages, including the cost
of remediation, which existed as a result of Hazardous Substances on the
Premises prior to the Start Date or which are caused by the gross negligence or
willful misconduct of Lessor, its agents or employees.  Lessor's obligations, as
and when required by the Applicable Requirements, shall include, but not be
limited to, the

                                       7
<PAGE>

cost of investigation, removal, remediation, restoration and/or
abatement, and shall survive the expiration or termination of this Lease.

          (f) Investigations and Remediations.  Lessor shall retain the
responsibility and pay for any investigations or remediation measures required
by governmental entities having jurisdiction with respect to the existence of
Hazardous Substances on the Premises prior to the Start Date, unless such
remediation measure is required as a result of Lessee's use (including
"Alterations", as defined in Paragraph 7.3(a) below) of the Premises, in which
event Lessee shall be responsible for such payment.  Lessee shall cooperate
fully in any such activities at the request of Lessor, including allowing Lessor
and Lessor's agents to have reasonable access to the Premises at reasonable
times in order to carry out Lessor's investigative and remedial
responsibilities.

          (g) Lessor Termination Option.  If a Hazardous Substance Condition
occurs during the term of this Lease, unless Lessee is legally responsible
therefor (in which case Lessee shall make the investigation and remediation
thereof required by the Applicable Requirements and this Lease shall continue in
full force and effect, but subject to Lessor's rights under Paragraph 6.2(d) and
Paragraph 13), Lessor may, at Lessor's option, either (i) investigate and
remediate such Hazardous Substance Condition, if required, as soon as reasonably
possible at Lessor's expense, in which event this Lease shall continue in full
force and effect, or (ii) if the estimated cost to remediate such condition
exceeds twelve (12) times the then monthly Base Rent or $100,000, whichever is
greater, give written notice to Lessee, within thirty (30) days after receipt by
Lessor of knowledge of the occurrence of such Hazardous Substance Condition, of
Lessor's desire to terminate this Lease as of the date sixty (60) days following
the date of such notice.  In the event Lessor elects to give a termination
notice, Lessee may, within ten (10) days thereafter, give written notice to
Lessor of Lessee's commitment to pay the amount by which the cost of the
remediation of such Hazardous Substance Condition exceeds an amount equal to
twelve (12) times the then monthly Base Rent or $100,000, whichever is greater.
Lessee shall provide Lessor with said funds or satisfactory assurance thereof
within thirty (30) days following such commitment.  In such event, this Lease
shall continue in full force and effect, and Lessor shall proceed to make such
remediation as soon as reasonably possible after the required funds are
available.  If Lessee does not give such notice and provide the required funds
or assurance thereof within the time provided, this Lease shall terminate as of
the date specified in Lessor's notice of termination.

     6.3  Lessee's Compliance with Applicable Requirements.  Except as otherwise
provided in this Lease, Lessee shall, at Lessee's sole expense, fully,
diligently and in a timely manner, materially comply with all Applicable
Requirements, the requirements of any applicable fire insurance underwriter or
rating bureau, and the recommendations of Lessor's engineers and/or consultants
which relate in any manner to the Premises, without regard to whether said
requirements are now in effect or became effective after the Start Date.  Lessee
shall, within ten (10) days after receipt of Lessor's written request, provide
Lessor with copies of all permits and other documents, and other information
evidencing Lessee's compliance with any Applicable Requirements specified by
Lessor, and shall immediately upon receipt, notify Lessor in writing (with
copies of any documents involved) of any threatened or actual claim, notice,
citation,

                                       8
<PAGE>

warning, complaint or report pertaining to or involving failure by Lessee or the
Premises to comply with any Applicable Requirements.

     6.4  Inspection; Compliance.  Lessor and Lessor's "Lender" (as defined in
Paragraph 30 below) and consultants shall have the right to enter into Premises
at any time, in the case of an emergency, and otherwise at reasonable times, for
the purpose of inspecting the condition of the Premises and for verifying
compliance by Lessee with this Lease.  The cost of any such inspections shall be
paid by Lessor, unless a violation of Applicable Requirements, or a
contamination is found to exist or be imminent, or the inspection is requested
or ordered by a governmental authority.  In such case, Lessee shall upon request
reimburse Lessor for the cost of such inspections, so long as such inspection is
reasonably related to the violation or contamination.

7. Maintenance; Repairs, Utility Installations, Trade Fixtures and Alterations.

     7.1  Lessee's Obligations.

          (a) In General.  Subject to the provisions of Paragraph 2.2
(Condition), 2.3 (Compliance), 6.3 (Lessee's Compliance with Applicable

practices, if the Basic Elements described in Paragraph 7.1(b) cannot be
repaired other than at a cost which is in excess of 50% of the cost of replacing
such Basic Elements, then such Basic Elements shall be replaced by Lessor, and
the cost thereof shall be prorated between the Parties and Lessee shall only be
obligated to pay, each month during the remainder of the term of this Lease, on
the date on which Base Rent is due, an amount equal to the product of
multiplying the cost of such replacement by a fraction, the numerator of which
is one, and the denominator of which is the number of months of the useful life
of such replacement as such useful life is specified pursuant to Federal income
tax regulations or guidelines for depreciation thereof (including interest on
the unamortized balance as is then commercially reasonable in the judgment of
Lessor's accountants), with Lessee reserving the right to prepay its obligation
at any time.

     7.2  Lessor's Obligations.  Subject to the provisions of Paragraph 2.2
(Condition), 2.3 (Compliance), 9 (Damage or Destruction), and 14 (Condemnation),
it is intended by the Parties hereto that Lessor have no obligation, in any
manner whatsoever, to repair and maintain the Premises, the improvements
therein, all of which obligations are intended to be that of the Lessee.  It is
the intention of the Parties that the terms of this Lease govern the respective
obligations of the Parties as to maintenance and repair of the Premises, and
they expressly waive the benefit of any statute now or hereafter in effect to
the extent it is inconsistent with the terms of this Lease.

     7.3  Utility Installations; Trade Fixtures; Alterations.

          (a) Definitions; Consent Required.  The term "Utility Installations"
refers to all floor and window coverings, air lines, power panels, electrical
distribution, security and fire protection systems, communication systems,
lighting fixtures, HVAC equipment, plumbing, and fencing in or on the Premises.
The term "Trade Fixtures" shall mean Lessee's machinery and equipment that can
be removed without doing material damage to the Premises.  The term
"Alterations" shall mean any modification of the improvements, other than
Utility Installations or Trade Fixtures, whether by addition or deletion.
"Lessee Owned Alterations and/or Utility Installations" are defined as
Alterations and/or Utility Installations made by Lessee that are not yet owned
by Lessor pursuant to Paragraph 7.4(a).  Lessee shall not make any Alterations
or Utility Installations to the Premises without Lessor's prior written consent.
Lessee may, however, make non-structural Utility Installations to the interior
of the Premises (excluding the roof) without such consent but upon notice to
Lessor, as long as they are not visible from the outside, do not involve
puncturing, relocating or removing the roof or any existing walls, and the
cumulative cost thereof during this Lease as extended does not exceed $50,000 in
the aggregate or $10,000 in any one year.

                                       10
<PAGE>

          (b) Consent.  Any Alterations or Utility Installations that Lessee
shall desire to make and which require the consent of the Lessor shall be
presented to Lessor in written form with detailed plans.  Consent shall be
deemed conditioned upon Lessee's:  (i) acquiring all applicable governmental
permits, (ii) furnishing Lessor with copies of both the permits and the plans
and specifications prior to commencement of the work, and (iii) compliance with
all conditions of said permits and other Applicable Requirements in a prompt and
expeditious manner.  Any Alterations or Utility Installations shall be performed
in a workmanlike manner with good and sufficient materials.  Lessee shall
promptly upon completion furnish Lessor with as-built plans and specifications.
For work which costs an amount equal to the greater of one month's Base Rent, or
$10,000, Lessor may condition its consent upon Lessee providing a lien and
completion bond in an amount equal to one and one-half times the estimated cost
of such Alteration or Utility Installation and/or upon Lessee's posting an
additional Security Deposit with Lessor.

          (c) Indemnification.  Lessee shall pay, when due, all claims for labor
or materials furnished or alleged to have been furnished to or for Lessee at or
for use on the Premises, which claims are or may be secured by any mechanics' or
materialmens' lien against the Premises or any interest therein.  Lessee shall
give Lessor not less than ten (10) days' notice prior to the commencement of any
work in, on or about the Premises, and Lessor shall have the right to post
notices of non-responsibility.  If Lessee shall contest the validity of any such
lien, claim or demand, then Lessee shall, at its sole expense defend and protect
itself, Lessor and the Premises against the same and shall pay and satisfy any
such adverse judgment that may be rendered thereon before the enforcement
thereof.  If Lessor shall require, Lessee shall furnish a surety bond in an
amount equal to one and one-half times the amount of such contested lien, claim
or demand, indemnifying Lessor against liability for the same.  If Lessor elects
to participate in any such action, Lessee shall pay Lessor's attorneys' fees and
costs.

     7.4  Ownership; Removal; Surrender; and Restoration.

          (a) Ownership.  Subject to Lessor's right to require removal or elect
ownership as hereinafter provided, all Alterations and Utility Installations
made by Lessee shall be the property of Lessee, but considered a part of the
Premises.  Lessor may, at any time, elect in writing to be the owner of all or
any specified part of the Lessee Owned Alterations and Utility Installations.
Unless otherwise instructed per Paragraph 7.4(b) hereof, all Lessee Owned
Alterations and Utility Installations shall, at the expiration or termination of
this Lease, become the property of Lessor and be surrendered by Lessee with the
Premises.

          (b) Removal.

          (c) Surrender/Restoration.  Lessee shall surrender the Premises by the
Expiration Date or any earlier termination date, with all of the improvements,
parts and surfaces

                                       11
<PAGE>

thereof broom clean and free of debris, and in good operating order, condition
and state of repair, ordinary wear and tear excepted. "Ordinary wear and tear"
shall not include any damage or deterioration that would have been prevented by
good maintenance practice. Lessee shall repair any damage occasioned by the
installation, maintenance or removal of Trade Fixtures, Lessee Owned Alterations
and/or Utility Installations, furnishings, and equipment as well as the removal
of any storage tank installed by or for Lessee, and the removal, replacement or
remediation of any soil, material or groundwater contaminated by Lessee. Trade
Fixtures shall remain the property of Lessee and shall be removed by Lessee. The
failure by Lessee to timely vacate the Premises pursuant to this Paragraph
7.4(c) without the express written consent of Lessor shall constitute a holdover
under the provisions of Paragraph 26 below. See Addendum 7.4.

8.  Insurance; Indemnity.

     8.1  Payment For Insurance.  Lessee shall pay for all insurance required
under Paragraph 8 except to the extent of the cost attributable to liability
insurance carried by Lessor under Paragraph 8.2(b) in excess of $2,000,000 per
occurrence.  Premiums for policy periods commencing prior to or extending beyond
the Lease term shall be prorated to correspond to the Lease term.  Payment shall
be made by Lessee to Lessor within ten (10) days following receipt of an
invoice.

     8.2  Liability Insurance.

          (a) Carried by Lessee.  Lessee shall obtain and keep in force a
Commercial General Liability Policy of insurance protecting Lessee and Lessor
against claims for bodily injury, personal injury and property damage based upon
or arising out of the ownership, use, occupancy or maintenance of the Premises
and all areas appurtenant thereto.  Such insurance shall be on an occurrence
basis providing single limit coverage in an amount not less than $2,000,000 per
occurrence with an "Additional Insured-Managers or Lessors of Premises
Endorsement" and contain the "Amendment of the Pollution Exclusion Endorsement"
for damage caused by heat, smoke or fumes from a hostile fire.  The Policy shall
not contain any intra-insured exclusions as between insured persons or
organizations, but shall include coverage for liability assumed under this Lease
as an "insured contract" for the performance of Lessee's indemnity obligations
under this Lease.  The limits of said insurance shall not, however, limit the
liability of Lessee nor relieve Lessee of any obligation hereunder.  All
insurance carried by Lessee shall be primary to and not contributory with any
similar insurance carried by Lessor, whose insurance shall be considered excess
insurance only.

          (b) Carried by Lessor.  Lessor shall maintain liability insurance as
described in Paragraph 8.2(a), in addition to, and not in lieu of, the insurance
required to be maintained by Lessee.  Lessee shall not be named as an additional
insured therein.

     8.3  Property Insurance--Building, Improvements and Rental Value.

          (a) Building and Improvements.  The Insuring Party shall obtain and
keep in force a policy or policies in the name of Lessor, with loss payable to
Lessor, any groundlessor, and to any Lender(s) insuring loss or damage to the
Premises.  The amount of such insurance

                                       12
<PAGE>

shall be equal to the full replacement cost of the Premises, as the same shall
exist from time to time, or the amount required by any Lenders, but in no event
more than the commercially reasonable and available insurable value thereof. If
Lessor is the Insuring Party, however, Lessee Owned Alterations and Utility
Installations, Trade Fixtures, and Lessee's personal property shall be insured
by Lessee under Paragraph 8.4 rather than by Lessor. If the coverage is
available and commercially appropriate, such policy or policies shall insure
against all risks of direct physical loss or damage (except the perils of flood
and/or earthquake unless required by a Lender), including coverage for debris
removal and the enforcement of any Applicable Requirements requiring the
upgrading, demolition, reconstruction or replacement of any portion of the
Premises as the result of a covered loss. Said policy or policies shall also
contain an agreed valuation provision in lieu of any coinsurance clause, waiver
of subrogation, and inflation guard protection causing an increase in the annual
property insurance coverage amount by a factor of not less than the adjusted
U.S. Department of Labor Consumer Price Index for All Urban Consumers for the
city nearest to where the Premises are located. If such insurance coverage has a
deductible clause, the deductible amount shall not exceed $1,000 per occurrence,
and Lessee shall be liable for such deducible amount in the event of an Insured
Loss.

          (b) Rental Value.  The Insuring Party shall obtain and keep in force a
policy or policies in the name of Lessor with loss payable to Lessor and Lender,
insuring the loss of the full Rent for one (1) year.  Said insurance shall
provide that in the event the Lease is terminated by reason of an insured loss,
the period of indemnity for such coverage shall be extended beyond the date of
the completion of repairs or replacement of the Premises, to provide for one
full year's loss of Rent from the date of any such loss.  Said insurance shall
contain an agreed valuation provision in lieu of any coinsurance clause, and the
amount of coverage shall be adjusted annually to reflect the projected Rent
otherwise payable by Lessee, for the next twelve (12) month period.  Lessee
shall be liable for any deductible amount in the event of such loss.

          (c) Adjacent Premises.  If the Premises are part of a larger building,
or of a group of buildings owned by Lessor which are adjacent to the Premises,
the Lessee shall pay for any increase in the premiums for the property insurance
of such building or buildings if said increase is caused by Lessee's acts,
omissions, use or occupancy of the Premises.

     8.4  Lessee's Property/Business Interruption Insurance.

          (a) Property Damage.  Lessee shall obtain and maintain insurance
coverage on all of Lessee's personal property, Trade Fixtures, and Lessee Owned
Alterations and Utility Installations.  Such insurance shall be full replacement
cost coverage with a deductible of not to exceed $1,000 per occurrence.  The
proceeds from any such insurance shall be used by Lessee for the replacement of
personal property, Trade Fixtures and Lessee Owned Alterations and Utility
Installations.  Lessee shall provide Lessor with written evidence that such
insurance is in force.

          (b) Business Interruption.  Lessee shall obtain and maintain loss of
income and extra expense insurance in amounts as will reimburse Lessee for
direct or indirect loss of

                                       13
<PAGE>

earnings attributable to all perils commonly insured against by prudent lessees
in the business of Lessee or attributable to prevention of access to the
Premises as a result of such perils.

          (c) No Representation of Adequate Coverage.  Lessor makes no
representation that the limits or forms of coverage of insurance specified
herein are adequate to cover Lessee's property, business operations or
obligations under this Lease.

     8.5  Insurance Policies.  Insurance required herein shall be by companies
duly licensed or admitted to transact business in the state where the Premises
are located, and maintaining during the policy term a "General Policyholders
Rating" of at least B+, V, as set forth in the most current issue of "Best's
Insurance Guide," or such other rating as may be required by a Lender.  Lessee
shall not do or permit to be done anything which invalidates the required
insurance policies.  Lessee shall, prior to the Start Date, deliver to Lessor
certified copies of policies of such insurance or certificates evidencing the
existence and amounts of the required insurance.  No such policy shall be
cancelable or subject to modification except after thirty (30) days prior
written notice to Lessor.  Lessee shall, at least thirty (30) days prior to the
expiration of such policies, furnish Lessor with evidence of renewals or
"insurance binders" evidencing renewal thereof, or Lessor may order such
insurance and charge the cost thereof to Lessee, which amount shall be payable
by Lessee to Lessor upon demand.  Such policies shall be for a term of at least
one year, or the length of the remaining term of this Lease, whichever is less.
If either party shall fail to procure and maintain the insurance required to be
carried by it, the other Party may, but shall not be required to, procure and
maintain the same.

     8.6  Waiver of Subrogation.  Without affecting any other rights or
remedies, Lessee and Lessor each hereby release and relieve the other, and waive
their entire right to recover damages against the other, for loss of or damage
to its property arising out of or incident to the perils required to be insured
against herein.  The effect of such releases and waivers is not limited by the
amount of insurance carried or required, or by any deductibles applicable
hereto.  The Parties agree to have their respective property damage insurance
carriers waive any right to subrogation that such companies may have against
Lessor or Lessee, as the case may be, so long as the insurance is not
invalidated thereby.

     8.7  Indemnity.  Except for Lessor's negligence willful misconduct, Lessee
shall indemnify, protect, defend and hold harmless the Premises, Lessor and its
agents, Lessor's master or ground lessor, partners and Lenders, from and against
any and all claims, loss of rents and/or damages, liens, judgments, penalties,
attorneys' and consultants' fees, expenses and/or liabilities arising out of,
involving, or in connection with, the use and/or occupancy of the Premises by
Lessee.  If any action or proceeding is brought against Lessor by reason of any
of the foregoing matters, Lessee upon notice shall defend the same at Lessee's
expense by counsel reasonably satisfactory to Lessor and Lessor shall cooperate
with Lessee in such defense.  Lessor need not have first paid any such claim in
order to be so indemnified.

     8.8  Exemption of Lessor from Liability.  Lessor shall not be liable for
injury or damage to the person or goods, wares, merchandise or other property of
Lessee, Lessee's employees, contractors, invitees, customers, or any other
person in or about the Premises,

                                       14
<PAGE>

whether such damage or injury is caused by or results from fire, steam,
electricity, gas, water or rain, or from the breakage, leakage, obstruction or
other defects of pipes, fire sprinklers, wires, appliances, plumbing, HVAC or
lighting fixtures, or from any other cause, whether the said injury or damage
results from conditions arising upon the Premises or upon other portions of the
Building of which the Premises are a part, or from other sources or places.
Lessor shall not be liable for any damages arising from any act or neglect of
any other tenant of Lessor. Notwithstanding Lessor's negligence or breach of
this Lease, Lessor shall under no circumstances be liable for injury to Lessee's
business or for any loss of income or profit therefrom.

9.  Damage or Destruction.

     9.1  Definitions.

          (a) "Premises Partial Damage" shall mean damage or destruction to the
improvements on the Premises, other than Lessee Owned Alterations and Utility
Installations, which can reasonably be repaired in six (6) months or less from
the date of the damage or destruction.  Lessor shall notify Lessee in writing
thirty (30) days from the date of the damage or destruction as to whether or not
the damage is Partial or Total.

          (b) "Premises Total Destruction" shall mean damage or destruction to
the Premises, other than Lessee Owned Alterations and Utility Installations and
Trade Fixtures, which cannot reasonably be repaired in six (6) months or less
from the date of the damage or destruction.  Lessor shall notify Lessee in
writing thirty (30) days from the date of the damage or destruction as to
whether or not the damage is Partial or Total.

          (c) "Insured Loss" shall mean damage or destruction to improvements on
the Premises, other than Lessee Owned Alterations and Utility Installations and
Trade Fixtures, which was caused by an event required to be covered by the
insurance described in Paragraph 8.3(a), irrespective of any deductible amounts
or coverage limits involved.

          (d) "Replacement Cost" shall mean the cost to repair or rebuild the
improvements owned by Lessor at the time of the occurrence to their condition
existing immediately prior thereto, including demolition, debris removal and
upgrading required by the operation of Applicable Requirements, and without
deduction for depreciation.

          (e) "Hazardous Substance Condition" shall mean the occurrence or
discovery of a condition involving the presence of, or a contamination by, a
Hazardous Substance as defined in Paragraph 6.2(a), in, on, or under the
Premises.

     9.2  Partial Damage - Insured Loss.  If a Premises Partial Damage that is
an Insured Loss occurs, then Lessor shall, at Lessor's expense, repair such
damage (but not Lessee's Trade Fixtures or Lessee Owned Alternations and Utility
Installations) as soon as reasonably possible and this Lease shall continue in
full force and effect; provided, however, that Lessee shall, at Lessor's
election, make the repair of any damage or destruction the total cost to repair
of which is $10,000 or less, and in such event, Lessor shall make any applicable
insurance proceeds

                                       15
<PAGE>

available to Lessee on a reasonable basis for that purpose. Notwithstanding the
foregoing, if the required insurance was not in force or the insurance proceeds
are not sufficient to effect such repair, the Insuring Party shall promptly
contribute the shortage in proceeds (except as to the deductible which is
Lessee's responsibility) as and when required to complete said repairs. In the
event, however, such shortage was due to the fact that, by reason of the unique
nature of the improvements, full replacement cost insurance coverage was not
commercially reasonable and available, Lessor shall have no obligation to pay
for the shortage in insurance proceeds or to fully restore the unique aspects of
the Premises unless Lessee provides Lessor with the funds to cover same, or
adequate assurance thereof, within ten (10) days following receipt of written
notice of such shortage and request therefor. If Lessor receives said funds or
adequate assurance thereof within said ten (10) day period, the party
responsible for making the repairs shall complete them as soon as reasonably
possible and this Lease shall remain in full force and effect. If such funds or
assurance are not received, Lessor may nevertheless elect by written notice to
Lessee within then (10) days thereafter to: (i) make such restoration and repair
as is commercially reasonable with Lessor paying any shortage in proceeds, in
which case this lease shall remain in full force and effect, or have this Lease
terminate thirty (30) days hereafter. Lessee shall not be entitled to
reimbursement of any funds contributed by Lessee to repair any such damage or
destruction. Premises Partial Damage due to flood or earthquake shall be subject
to Paragraph 9.3, notwithstanding that there may be some insurance coverage, but
the net proceeds of any such insurance shall be made available for the repairs
if made by either Party.

     9.3  Partial Damage - Uninsured Loss.  If a Premises Partial Damage that is
not an Insured Loss occurs, unless caused by a negligent or willful act of
Lessee (in which event Lessee shall make the repairs at Lessee's expense),
Lessor may either: (i) repair such damage as soon as reasonably possible at
Lessor's expense, in which event this Lease shall continue in full force and
effect, or (ii) terminate this Lease by giving written notice to Lessee within
thirty (30) days after receipt by Lessor of knowledge of the occurrence of such
damage.  Such termination shall be effective sixty (60) days following the date
of such date notice.  In the event Lessor elects to terminate this Lease, Lessee
shall have the right within ten (10) days after receipt of the termination
notice to give written notice to Lessor of Lessee's commitment to pay for the
repair of such damage without reimbursement from Lessor.  Lessee shall provide
Lessor with said funds or satisfactory assurance thereof within thirty (30) days
after making such commitment.  In such event this Lease shall continue in full
force and effect, and Lessor shall proceed to make such repairs as soon as
reasonably possible after the required funds are available.  If Lessee does not
make the required commitment, this Lease shall terminate as of the date
specified in the termination notice.

     9.4  Total Destruction.  Notwithstanding any other provision hereof, if a
Premises Total Destruction occurs, this Lease shall terminate sixty (60) days
following such Destruction.  If the damage or destruction was caused by the
gross negligence or willful misconduct of Lessee, Lessor shall have the right to
recover Lessor's damages from Lessee, except as provided in Paragraph 8.6.

     9.5  Damage Near End of Term.  If at any time during the last six (6)
months of this Lease there is damage for which the cost to repair exceeds one
(1) month's Base Rent, whether

                                       16
<PAGE>

or not an Insured Loss, Lessor may terminate this Lease effective sixty (60)
days following the date of occurrence of such damage by giving a written
termination notice to Lessee within thirty (30) days after the date of
occurrence of such damage. Notwithstanding the foregoing, if Lessee at that time
has an exercisable option to extend this Lease or to purchase the Premises, then
Lessee may preserve this Lease by, (a) exercising such option and (b) providing
Lessor with any shortage in insurance proceeds (or adequate assurance thereof)
needed to make the repairs on or before the earlier of (i) the date which is ten
days after Lessee's receipt of Lessor's written notice purporting to terminate
this Lease, or (ii) the day prior to the date upon which such option expires. If
Lessee duly exercises such option during such period and provides Lessor with
funds (or adequate assurance thereof) to cover any shortage in insurance
proceeds, Lessor shall, at Lessor's commercially reasonable expense, repair such
damage as soon as reasonably possible and this Lease shall continue in full
force and effect. If Lessee fails to exercise such option and provide such funds
or assurance during such period, then this Lease shall terminate on the date
specified in the termination notice and Lessee's option shall be extinguished.

     9.6  Abatement of Rent; Lessee's Remedies.

          (a) Abatement.  In the event of Premises Partial Damage or Premises
Total Destruction or a Hazardous Substance Condition for which Lessee is not
responsible under this Lease, the Rent payable by Lessee for the period required
for the repair, remediation or restoration of such damage shall be abated in
proportion to the degree to which Lessee's use of the Premises is impaired, but
not to exceed the proceeds received from the Rental Value Insurance.  All other
obligations of Lessee shall be performed by Lessee, and Lessor shall have no
liability for any such damage, destruction, remediation, repair or restoration
except as provided herein.

          (b) Remedies.  If Lessor shall obligated to repair or restore the
Premises and does not commence, in a substantial and meaningful way, such repair
or restoration within ninety (90) days after such obligation shall accrue,
Lessee may, at any time prior to the commencement of such repair or restoration,
give written notice to Lessor and to any Lenders of which Lessee has actual
notice, of Lessee's election to terminate this Lease on a date not less than
sixty (60) days following the giving of such notice.  If Lessee gives such
notice and such repair or restoration is not commenced within thirty (30) days
hereafter, this Lease shall terminate as of the date specified in said notice.
If the repair or restoration is commenced within said thirty (30) days, this
Lease shall continue in full force and effect.  "Commence" shall mean either the
unconditional authorization of the preparation of the required plan, or the
beginning of the actual work of the Premises, whichever first occurs.

     9.7  Termination-Advance Payments.  Upon termination of this Lease pursuant
to (S) 6.2(g) or Paragraph 9, an equitable adjustment shall be made concerning
advance Base Rent and any other advance payments made by Lessee to Lessor.
Lessor shall, in addition, return to Lessee so much of Lessee's Security Deposit
as has not been, or is not then required to be, used by Lessor.

                                       17
<PAGE>

     9.8  Waive Statutes.  Lessor and Lessee agree that the terms of this Lease
shall govern the effect of any damage to or destruction of the Premises with
respect to the termination of this Lease and hereby waive the provisions of any
present or future statute to the extent inconsistent herewith.

10.  Real Property Taxes.

     10.1  Definition of "Real Property Taxes."  As used herein, the term "Real
Property Taxes" shall include any form of assessment; real estate, general,
special, ordinary or extraordinary, or rental levy or tax (other than
inheritance, personal income or estate taxes); improvement bond; and/or license
fee imposed upon or levied against any legal or equitable interest of Lessor in
the Premises, Lessor's right to other income thereof and/or Lessor's business of
leasing, by any authority having the direct or indirect power to tax and where
the funds are generated with reference to the Building address and where the
proceeds so generated are to be applied by the city, county or other local
taxing authority of a jurisdiction within which the Premises are located.  The
term "Real Property Taxes" shall also include any tax, fee, levy, assessment or
charge, or any increase therein, imposed by reason of events occurring during
the term of this Lease, including but not limited to, a change in the ownership
of the Premises.

     10.2  (a)  Payment of Taxes.  Lessee shall pay the Real Property Taxes
applicable to the Premises during the term of this Lease.  Subject to Paragraph
10.2(b), all such payments shall be made at least ten (10) days prior to any
delinquency date.  Lessee shall promptly furnish lessor with satisfactory
evidence that such taxes have been paid.  If any such taxes shall cover any
period of time prior to or after the expiration or termination of this Lease,
Lessee's share of such taxes shall be prorated to cover only that portion of the
tax bill applicable to the period that this Lease is in effect, and Lessor shall
reimburse Lessee for any overpayment.  If Lessee shall fail to pay any required
Real Property Taxes, Lessor shall have the right to pay the same, and Lessee
shall reimburse lessor therefor upon demand.

          (b) Advance Payment.  In the event Lessee incurs a late charge on any
Rent payment, Lessor may, at Lessor's option, estimate the current Real Property
Taxes, and require that such taxes be paid in advance to lessor by Lessee,
either:  (i) in a lump sum amount equal to the installment due, at least twenty
(20) days prior to the applicable delinquency date, or (ii) monthly in advance
with the payment of the Base Rent.  If Lessor elects to require payment monthly
in advance, the monthly payment shall be an amount equal to the amount of the
estimated installment of taxes divided by the number of months remaining before
the month in which said installment becomes delinquent.  When the actual amount
of the applicable tax bill is known, the amount of such equal monthly advance
payments shall be adjusted as required to provide the funds needed to pay the
applicable taxes.  If the amount collected by Lessor is insufficient to pay such
Real Property Taxes when due, Lessee shall pay Lessor, upon demand, such
additional sums as are necessary to pay such obligations.  All moneys paid to
Lessor under this Paragraph may be intermingled with other moneys of Lessor and
shall not bear interest.  In the event of a Breach by Lessee in the performance
of its obligations under this Lease, then any balance of funds paid to Lessor
under the provisions of this Paragraph may, at the option of Lessor, be treated
as an additional Security Deposit.

                                       18
<PAGE>

     10.3  Joint Assessment.  If the Premises are not separately assessed,
Lessee's liability shall be an equitable proportion of the Real Property Taxes
for all the land and improvements included within the tax parcel assessed, such
proportion to be conclusively determined by Lessor from the respective
valuations assigned in the assessor's work sheets or such other information as
may be reasonably available.

     10.4  Personal Property Taxes.  Lessee shall pay, prior to delinquency, all
taxes assessed against and levied upon Lessee Owned Alterations, Utility
Installations, Trade Fixtures, furnishings, equipment and all personal property
of Lessee.  When possible, Lessee shall cause its property to be assessed and
billed separately from the real property of Lessor.  If any of Lessee's said
personal property shall be assessed with Lessor's real property, Lessee shall
pay Lessor the taxes attributable to Lessee's Property within ten (10) days
after receipt of a written statement.

11.  Utilities.  Lessee shall pay for all water, gas, heat, light, power,
telephone, trash disposal and other utilities and services supplied to the
Premises, together with any taxes thereon.  If any such services are not
separately metered to Lessee, Lessee shall pay a reasonable proportion, to be
determined by Lessor, of all charges jointly metered.

12.  Assignment and Subletting.

     12.1  Lessor's Consent Required.

          (a) Lessee shall not voluntarily or by operation of law assign,
transfer, mortgage or encumber (collectively, "Assignment") or sublet all or any
part of Lessee's interest in this Lease or in the Premises without Lessor's
prior written consent.

          (b) A change in the control of Lessee shall constitute an assignment
requiring consent.  The transfer, on a cumulative basis, of twenty-five percent
(25%) or more of the voting control of Lessee shall constitute a change in
control for this purpose.

          (c) The involvement of Lessee or its assets in any transaction, or
series of transactions (by way of merger, sale, acquisition, financing,
transfer, leveraged buy-out or otherwise), whether or not a formal assignment or
hypothecation of this Lease or Lessee's assets occurs, which results or will
result in a reduction of the Net Worth of Lessee, by an amount greater than
twenty-five percent (25%) of such Net Worth as it was represented at the time of
the execution of this Lease or at the time of the most recent assignment to
which Lessor has consented, or as it exists immediately prior to said
transaction or transactions constituting such reduction, whichever was or is
greater, shall be considered an assignment of this Lease to which Lessor may
reasonably withhold its consent.  "Net Worth of Lessee" shall mean the net worth
of Lessee (excluding any guarantors) established under generally accepted
accounting principles.

          (d) An assignment or subletting without consent shall, at Lessor's
option, be a Default curable after notice per Paragraph 13.1(c), or a noncurable
Breach without the necessity of any notice and grace period.  If Lessor elects
to treat such unapproved to assignment or subletting as a noncurable Breach,
Lessor may either: (i) terminate this Lease, or (ii) upon thirty

                                       19
<PAGE>

(30) days written notice, increase the monthly Base Rent to one hundred ten
percent (110%) of the Base Rent then in effect. Further, in the event of such
Breach and rental adjustment, (i) the purchase price of any option to purchase
the Premises held by Lessee shall be subject to similar adjustment to one
hundred ten percent (110%) of the price previously in effect, and (ii) all fixed
and non-fixed rental adjustments scheduled during the remainder of the Lease
term shall be increased to One Hundred Ten Percent (110%) of the scheduled
adjusted rent.

          (e) Lessee's remedy for any breach of Paragraph 12.1 by Lessor shall
be limited to compensatory damages and/or injunctive relief.

     12.2  Terms and Conditions Applicable to Assignment and Subletting.

          (a) Regardless of Lessor's consent, any assignment or subletting shall
not: (i) be effective without the express written assumption by such assignee or
sublessee of the obligations of Lessee under this Lease, (ii) release Lessee of
any obligations hereunder, or (iii) alter the primary liability of Lessee for
the payment of Rent or for the performance of any other obligations to be
performed by Lessee.

          (b) Lessor may accept Rent or performance of Lessee's obligations from
any person other than Lessee pending approval or disapproval of an assignment.
Neither a delay in the approval or disapproval of such assignment nor the
acceptance of Rent or performance shall constitute a waiver or estoppel of
Lessor's right to exercise its remedies for Lessee's Default or Breach.

          (c) Lessor's consent to any assignment or subletting shall not
constitute a consent to any subsequent assignment or subletting.

          (d) In the event of any Default or Breach by Lessee, Lessor may
proceed directly against Lessee, any Guarantors or any one else responsible for
the performance of Lessee's obligations under this Lease, including any assignee
or sublessee, without first exhausting Lessor's remedies against any other
person or entity responsible therefore to Lessor, or any security held by
Lessor.

          (e) Each request for consent to an assignment or subletting shall be
in writing, accompanied by information relevant to Lessor's determination as to
the financial and operational responsibility and appropriateness of the proposed
assignee or sublessee, including but not limited to the intended use and/or
required modification of the Premises, if any, together with a fee of $1,000 or
ten percent (10%) of the current monthly Base Rent applicable to the portion of
the Premises which is the subject of the proposed assignment or sublease,
whichever is greater, as consideration for Lessor's considering and processing
said request.  Lessee agrees to provide Lessor with such other or additional
information and/or documentation as may be reasonably requested.

          (f) Any assignee of, or sublessee under, this Lease shall, by reason
of accepting such assignment or entering into such sublease, be deemed, to have
assumed and agreed to conform and comply with each and every term, covenant,
condition and obligation

                                       20
<PAGE>

herein to be observed or performed by Lessee during the term of said assignment
or sublease, other than such obligations as are contrary to or inconsistent with
provisions of an assignment or sublease to which Lessor has specifically
consented to in writing.

     12.3  Additional Terms and Conditions Applicable to Subletting.  The
following terms and conditions shall apply to any subletting by Lessee of all or
any part of the Premises and shall be deemed included in all subleases under
this Lease whether or not expressly incorporated therein:

          (a) Lessee hereby assigns and transfers to Lessor all of Lessee's
interest in all Rent payable on any sublease, and Lessor may collect such Rent
and apply same toward Lessee's obligations under this Lease; provided, however,
that until a Breach shall occur in the performance of Lessee's obligations,
Lessee may collect such Rent.  Lessor shall not, by reason of the foregoing or
any assignment of such sublease, nor by reason of the collection of Rent, by
deemed liable to the sublessee for any failure of Lessee to perform and comply
with any of Lessee's obligations to such sublessee.  Lessee hereby irrevocably
authorizes and directs any such sublessee, upon receipt of a written notice from
Lessor stating that a Breach exists in the performance of Lessee's obligations
under this Lease, to pay to Lessor all Rent due and to become due under the
sublease.  Sublessee shall rely upon any such notice from Lessor and shall pay
all Rents to Lessor without any obligation or right to inquire as to whether
such Breach exists, notwithstanding any claim from Lessee to the contrary.

          (b) In the event of a Breach by Lessee, Lessor may, at its option,
require sublessee to attorn to Lessor, in which event Lessor shall undertake the
obligations of the sublessor under such sublease from the time of the exercise
of said option to the expiration of such sublease; provided, however, Lessor
shall not be liable for any prepaid rents or security deposit paid by such
sublessee to such sublessor or for any prior Defaults or Breaches of such
sublessor.

          (c) Any matter requiring the consent of the sublessor under a sublease
shall also require the consent of Lessor herein.

          (d) No sublessee shall further assign or sublet all or any part of the
Premises without Lessor's prior written consent.

          (e) Lessor shall deliver a copy of any notice of Default or Breach by
Lessee to the sublessee, who shall have the right to cure the Default of Lessee
within the grace period, if any, specified in such notice.  The sublessee shall
have a right of reimbursement and offset from and against Lessee for any such
Defaults cured by the sublessee.

13.  Default; Breach; Remedies.

     13.1  Default; Breach.  A "Default" is defined as a failure by the Lessee
to comply with or perform any of the terms, covenants, conditions or rules under
this Lease.  a "Breach" is defined as the occurrence of one or more of the
following Defaults, and the failure of Lessee to cure such Default within any
applicable grace period:

                                       21
<PAGE>

          (a) The abandonment of the Premises; or the vacating of the Premises
without providing a commercially reasonable level or security, or where the
coverage of the property insurance describe in Paragraph 8.3 is jeopardized as a
result thereof, or without providing reasonable assurances to minimize potential
vandalism.

          (b) The failure of Lessee to make any payment of Rent or any Security
Deposit required to be made by Lessee hereunder, whether to Lessor or to a third
party, when due, to provide reasonable evidence of insurance or surety bond, or
to fulfill any obligation under this Lease which endangers or threatens life or
property, where such failure continues for a period of three (3) business days
following written notice to Lessee.

          (c) The failure by Lessee to provide (i) reasonable written evidence
of compliance with Applicable Requirements, (ii) the service contracts, (iii)
the rescission of an unauthorized assignment or subletting, (iv) a Tenancy
Statement, (v) a requested subordination, (vi) evidence concerning any guaranty
and/or Guarantor, (vii) any document requested under Paragraph 42 (easements),
or (viii) any other documentation or information which Lessor may reasonably
require of Lessee under the terms of this Lease, where any such failure
continues for a period of ten (10) days following written notice to Lessee.

          (d) A Default by Lessee as to the terms, covenants, conditions or
provisions of this Lease, or of the rules adopted under Paragraph 40 hereof,
other than those described in subparagraphs 13.1(a), (b) or (c), above, where
such Default continues for a period of thirty (30) days after written notice;
provided, however, that if the nature of Lessee's Default is such that more than
thirty (30) days are reasonably required for its cure, then it shall not be
deemed to be a Breach if Lessee commences such cure within said thirty (30) day
period and thereafter diligently prosecutes such cure to completion.

          (e) The occurrence of any of the following events: (i) the making of
any general arrangement or assignment for the benefit of creditors; (ii)
becoming a "debtor" as defined in 11 U.S.C. Section 101 or any successor statute
thereto (unless, in the case of a petition filed against Lessee, the same is
dismissed within sixty (60) days; (iii) the appointment of a trustee or receiver
to take possession of 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 (30) days; or (iv) the attachment, execution or other
judicial seizure of 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; provided, however, in the event that any provision of
this subparagraph (e) is contrary to any applicable law, such provision shall be
of no force or effect, and not affect the validity of the remaining provisions.

          (f) The discovery that any financial statement of Lessee or of any
Guarantor given to Lessor was materially false.

          (g) If the performance of Lessee's obligations under this Lease is
guaranteed:  (i) the death of a guarantor, (ii) the termination of a guarantor's
liability with respect to this Lease other than in accordance with the terms of
such guaranty, (iii) a guarantor's becoming insolvent or the subject of a
bankruptcy filing, (iv) a Guarantor's refusal to honor the guaranty, or

                                       22
<PAGE>

(v) a Guarantor's breach of its guaranty obligation on an anticipatory breach
basis, and Lessee's failure, within sixty (60) days following written notice by
or on behalf of Lessor to Lessee of any such event, to provide Lessor with
written alternative assurance or security, which, when coupled with the then
existing resources of Lessee, equals or exceeds the combined financial resources
of Lessee and the guarantors that existed at the time of execution of this
Lease.

    13.2  Remedies.  If Lessee fails to perform any of its affirmative duties or
obligations, within ten (10) days after written notice (or in case of an
emergency, without notice), Lessor may, at its option, perform such duty or
obligation on Lessee's behalf, including but not limited to the obtaining of
reasonably required bonds, insurance policies, or governmental licenses, permits
or approvals.  The costs and expenses of any such performance by Lessor shall be
due and payable by Lessee upon receipt of invoice therefor.  If any check given
to Lessor by Lessee shall not be honored by the bank upon which it is drawn,
Lessor, at its option, may require all future payments to be made by Lessee to
be by cashier's check.  In the event of a Breach, Lessor may, with or without
further notice or demand, and without limiting Lessor in the exercise of any
right or remedy which Lessor may have by reason of such Breach:

          (a) Terminate Lessee's right to possession of the Premises by any
lawful means, in which case this Lease shall terminate and Lessee shall
immediately surrender possession to Lessor.  In such event Lessor shall be
entitled to recover from Lessee: (i) the unpaid Rent which had been earned at
the time of termination; (ii) the worth at the time of award of the amount by
which the unpaid rent which would have been earned after termination until the
time of award exceeds the amount of such rental loss that the Lessee proves
could have been reasonably avoided; (iii) the worth at the time of award of the
amount by which the unpaid rent for the balance of the term after the time of
award exceeds the amount of such rental loss that the Lessee proves could be
reasonably avoided; and (iv) any other amount necessary to compensate Lessor for
all the detriment proximately caused by the Lessee's failure to perform its
obligations under this Lease or which in the ordinary course of things would be
likely to result therefrom, including but not limited to the cost of recovering
possession of the Premises, expenses of reletting, including necessary
renovation and alteration of the Premises, reasonable attorneys' fees, and that
portion of any leasing commission paid by Lessor in connection with this Lease
applicable to the unexpired term of this Lease.  The worth at the time of award
of the amount referred to in provision (iii) of the immediately preceding
sentence shall be computed by discounting such amount at the discount rate of
the Federal Reserve Bank of the District within which the Premises are located
at the time of award plus one percent (1%).  Efforts by Lessor to mitigate
damages caused by Lessee's Breach of this Lease shall not waive Lessor's right
to recover damages under Paragraph 12.  If termination of this Lease is obtained
through the provisional remedy of unlawful detainer, Lessor shall have the right
to recover in such proceeding any unpaid Rent and damages as are recoverable
therein, or Lessor may reserve the right to recover all or any part thereof in a
separate suit.  If a notice and grace period required under Paragraph 13.1 was
not previously given, a notice to pay rent or quit, or to perform or quit given
to Lessee under the unlawful detainer statute shall also constitute the notice
required by Paragraph 13.1.  In such case, the applicable grace period required
by Paragraph 13.1 and the unlawful detainer statute shall run concurrently and
the failure of Lessee to cure the Default within the greater of the two such
grace periods shall constitute both an unlawful detainer and a

                                       23
<PAGE>

Breach of this Lease entitling Lessor to the remedies provided for in this Lease
and/or by said statute.

          (b) Continue the Lease and Lessee's right to possession and recover
the Rent as it becomes due, in which event Lessee may sublet or assign, subject
only to reasonable limitations.  Acts of maintenance, efforts to relet, and/or
the appointment of a receiver to protect the Lessor's interests, shall not
constitute a termination of the Lessee's right to possession.

          (c) Pursue any other remedy now or hereafter available under the laws
or judicial decisions of the state wherein the Premises are located.  The
expiration or termination of this Lease and/or the termination of Lessee's right
to possession shall not relieve Lessee from liability under any indemnity
provisions of this Lease as to matters occurring or accruing during the hereof
or by reason of Lessee's occupancy of the Premises.

     13.3  Inducement Recapture.  Any agreement for free or abated rent or other
charges, or for the giving or paying by Lessor to or for Lessee of any cash or
other bonus, inducement or consideration for Lessee's entering into this Lease,
all of which concessions are hereinafter referred to as "Inducement Provisions,"
shall be deemed conditioned upon Lessee's full and faithful performance of all
of the terms, covenants and conditions of this Lease.  Upon Breach of this Lease
by Lessee, any such Inducement Provision shall automatically be deemed deleted
from this Lease and of no further force or effect, and any rent, other charge,
bonus, inducement or consideration theretofore abated, given or paid by Lessor
under such an Inducement Provision shall be immediately due and payable by
Lessee to Lessor, notwithstanding any subsequent cure of said Breach by Lessee.
The acceptance by Lessor of rent or the cure of the Breach which initiated the
operation of this paragraph shall not be deemed a waiver by Lessor of the
provisions of this paragraph unless specifically so stated in writing by Lessor
at the time of such acceptance.

     13.4  Late Charges.  Lessee hereby acknowledges that late payment by Lessee
of Rent 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 limited to, processing and accounting charges, and late
charges which may be imposed upon Lessor by any Lender.  Accordingly, if any
Rent shall not be received by Lessor within five (5) days after such amount
shall be due, then, without any requirement for notice to Lessee, Lessee shall
pay to Lessor a one-time late charge equal to ten percent (10%) of each such
overdue amount.  The parties hereby agree that such late charge represents a
fair and reasonable estimate of the costs Lessor will incur by reason of such
late payment.  Acceptance of such late charge by Lessor shall in no event
constitute a waiver of Lessee's Default or Breach with respect to such overdue
amount, nor prevent the exercise of any of the other rights and remedies granted
hereunder.  In the event that a late charge is payable hereunder, whether or not
collected, for three (3) consecutive installments of Base Rent, then
notwithstanding any provision of this Lease to the contrary, Base Rent shall, at
Lessor's option, become due and payable quarterly in advance.

     13.5  Interest.  Any monetary payment due Lessor hereunder, other than late
charges, not received by Lessor, when due as to scheduled payments (such as Base
Rent) or within thirty (30) days following the date on which it was due for non-
scheduled payment, shall bear interest

                                       24
<PAGE>

from the date when due, as to scheduled payments, or the thirty-first (31st) day
after it was due as to non-scheduled payments. The interest ("Interest") charged
shall be equal to the prime rate reported in the Wall Street Journal as
published closest prior to the date when due plus four percent (4%), but shall
not exceed the maximum rate allowed by law. Interest is payable in addition to
the potential late charge provided for in Paragraph 13.4.

     13.6  Breach by Lessor.

          (a) Notice of Breach.  Lessor shall not be deemed in breach of this
Lease unless Lessor fails within a reasonable time to perform an obligation
required to be performed by Lessor.  For purposes of this Paragraph, a
reasonable time shall in no event be less than thirty (30) days after receipt by
Lessor, and any Lender whose name and addresses shall have been furnished Lessee
in writing for such purpose, of written notice specifying wherein such
obligation of Lessor has not been performed; provided, however, that if the
nature of Lessor's obligation is such that more than thirty (30) days are
reasonably required for its performance, then Lessor shall not be in breach if
performance is commenced within such thirty (30) day period and thereafter
diligently pursued to completion.

          (b) Performance by Lessee on Behalf of Lessor.  In the event that
neither Lessor nor Lender cures said breach within thirty (30) days after
receipt of said notice, or if having commenced said cure they do not diligently
pursue it to completion, then Lessee may elect to cure said breach at Lessee's
expense and offset from Rent an amount equal to the greater of one month's Base
Rent or the Security Deposit, and to pay an excess of such expense under
protest, reserving Lessee's right to reimbursement from Lessor.  Lessee shall
document the cost of said cure and supply said documentation to Lessor.

14.  Condemnation.  If the Premises or any portion thereof are taken under the
power of eminent domain or sold under the threat of the exercise of said power
(collectively "Condemnation"), this Lease shall terminate as to the part taken
as of the date the condemning authority takes title or possession, whichever
first occurs.  If more than ten percent (10%) of any building portion of the
premises, or more than twenty-five percent (25%) of the land area portion of the
premises not occupied by any building, is taken by Condemnation, Lessee may, at
Lessee's option, to be exercised in writing within ten (10) days after Lessor
shall have given Lessee written notice of such taking (or in the absence of such
notice, within ten (10) days after the condemning authority shall have taken
possession) terminate this Lease as of the date the condemning authority takes
such possession.  If Lessee does not terminate this Lease in accordance with the
foregoing, this Lease shall remain in full force and effect as to the portion of
the Premises remaining, except that the Base Rent shall be reduced in proportion
to the reduction in utility of the Premises caused by such Condemnation.
Condemnation awards and/or payments shall be the property of Lessor, whether
such award shall be made as compensation for diminution in value of the
leasehold, the value of the part taken, or for severance damages; provided,
however, that Lessee shall be entitled to any compensation for Lessee's
relocation expenses, loss of business goodwill and/or Trade Fixtures, without
regard to whether or not this Lease is terminated pursuant to the provisions of
this Paragraph.  All Alterations and Utility Installations made to the Premises
by Lessee, for purposes of Condemnation only, shall be

                                       25
<PAGE>

considered the property of the Lessee and Lessee shall be entitled to any and
all compensation which is payable therefor. In the event that this Lease is not
terminated by reason of the Condemnation, Lessor shall repair any damage to the
Premises caused by such Condemnation.

15.  Broker's Fee.  Not applicable.

     15.1.  Additional Commission.  In addition to the payments owed pursuant to
Paragraph 1.10 above, and unless Lessor and the Brokers otherwise agree in
writing, Lessor agrees that:  (a) if Lessee exercises any Option, (b) if Lessee
acquires any rights to the Premises or other premises owned by Lessor and
located within the same Project, if any, within which the Premises is located,
(c) if Lessee remains in possession of the Premises, with the consent of Lessor,
after the expiration of this Lease, or (d) if Base Rent is increased, whether by
agreement or operation of an escalation clause herein, then, Lessor shall pay
Brokers a fee in accordance with the schedule of said Brokers in effect at the
time of the execution of this Lease.

     15.2  Assumption of Obligations.  Any buyer or transferee of Lessor's
interest in this Lease shall be deemed to have assumed Lessor's obligation
hereunder.  Each Broker shall be a third party beneficiary of the provisions of
Paragraphs 1.10, 15, 22 and 31.  If Lessor fails to pay to a Broker any amounts
due as and for commissions pertaining to this Lease when due, then such amounts
shall accrue Interest.  In addition, if Lessor fails to pay any amounts to
Lessee's Broker when due, Lessee's Broker may send written notice to Lessor and
Lessee of such failure and if Lessor fails to pay such amounts within ten (10)
days after said notice, Lessee shall pay said monies to its Broker and offset
such amounts against Rent.  In addition, Lessee's Broker shall be deemed to be a
third party beneficiary of any commission agreement entered into by and/or
between Lessor and Lessor's Broker.

     15.3  Representations and Indemnities of Broker Relationships.  Lessee and
Lessor each represent and warrant to the other that it has had no dealings with
any person, firm, broker or finder (other than the Brokers, if any) in
connection with this Lease, and that no one other than said named Brokers is
entitled to any commission or finder's fee in connection herewith.  Lessee and
Lessor do each hereby agree to indemnify, protect, defend and hold the other
harmless from and against liability for compensation or charges which may be
claimed by any such unnamed broker, finder or other similar party by reason of
any dealings or actions of the indemnifying Party, including any costs,
expenses, attorneys' fees reasonably incurred with respect thereto.

16.  Estoppel Certificates.

          (a) Each Party (as "Responding Party") shall within ten (10) days
after written notice from the other Party (the "Requesting Party") execute,
acknowledge and deliver to the Requesting Party a statement in writing in form
similar to the then most current "Estoppel Certificate" form published by the
American Industrial Real Estate Association, plus such additional information,
confirmation and/or statements as may be reasonably requested by the Requesting
Party.

          (b) If the Responding Party shall fail to execute or deliver the
Estoppel Certificate within such ten day period, the Requesting Party may
execute an Estoppel Certificate

                                       26
<PAGE>

stating that: (i) the Lease is in full force and effect without modification
except as may be represented by the Requesting Party, (ii) there are no uncured
defaults in the Requesting Party's performance, and (iii) if Lessor is the
Requesting Party, not more than one month's rent has been paid in advance.
Prospective purchasers and encumbrancers may rely upon the Requesting Party's
Estoppel Certificate, and the Responding Party shall be estopped from denying
the truth of the facts contained in said Certificate.

          (c) If Lessor desires to finance, refinance, or sell the Premises, or
any part thereof, Lessee and all Guarantors shall deliver to any potential
lender or purchaser designated by Lessor such financial statements as may be
reasonably required by such lender or purchaser, including but not limited to
Lessee's financial statements for the past three (3) years.  All such financial
statements shall be received by Lessor and such lender or purchaser in
confidence and shall be used only for the purposes herein set forth.

17.  Definition of Lessor.  The term "Lessor" as used herein shall mean the
owner or owners at the time in question of the fee title to the Premises, or, if
this is a sublease, of the Lessee's interest in the prior lease.  In the event
of a transfer of Lessor's title or interest in the Premises or in this Lease,
Lessor shall deliver to the transferee or assignee (in cash or by credit) any
unused Security Deposit held by Lessor.  Except as provided in Paragraph 15,
upon such transfer or assignment and deliver of the Security Deposit, as
aforesaid, the prior Lessor shall be relieved of all liability with respect to
the obligations and /or covenants in this Lease to be performed by the Lessor
shall be binding only upon the Lessor as hereinabove defined.  Notwithstanding
the above, and subject to the provisions of Paragraph 20 below, the original
Lessor under this Lease, and all subsequent holders of the Lessor's interest in
this Lease shall remain liable and responsible with regard to the potential
duties and liabilities of Lessor pertaining to Hazardous Substances as outlined
in Paragraph 6 above.

18.  Severability.  The invalidity of any provision of this Lease, as determined
by a court of competent jurisdiction, shall in no way affect the validity of any
other provision hereof.

19.  Days.  Unless otherwise specifically indicated to the contrary, the word
"days" as used in this Lease shall mean and refer to calendar days.

20.  Limitation on Liability.  Subject to the provisions of Paragraph 17 above,
the obligations of Lessor under this Lease shall not constitute personal
obligations of Lessor, the individual partners of Lessor or its or their
individual partners, directors, officers or shareholders, and Lessee shall look
to the Premises, and to no other assets of Lessor, for the satisfaction of any
liability of Lessor with respect to this Lease, and shall not seek recourse
against the individual partners of Lessor, or its or their individual partners,
directors, officers or shareholders, or any of their personal assets for such
satisfaction.

21.  Time of Essence.  Time is of the essence with respect to the performance of
all obligations to be performed or observed by the Parties under this Lease.

22.  No Prior or Other Agreements; Broker Disclaimer.  This Lease contains all
agreements between the Parties with respect to any matter mentioned herein, and
no other prior

                                       27
<PAGE>

or contemporaneous agreement or understanding shall be effective. Lessor and
Lessee each represents and warrants to the Brokers that it has made, and is
relying solely upon, its own investigation as to the nature, quality, character
and financial responsibility of the other Party to this Lease and as to the
nature, quality and character of the Premises. Brokers have no responsibility
with respect thereto or with respect to any default or breach hereof by either
Party. The liability (including court costs and Attorneys' fees), of any Broker
with respect to negotiation, execution, deliver or performance by either Lessor
or Lessee under this Lease or any amendment or modification hereto shall be
limited to an amount up to the fee received by such Broker pursuant to this
Lease; provided, however, that the foregoing limitation on each Broker's
liability shall not be applicable to any gross negligence or willful misconduct
of such Broker.

23.  Notices.

     23.1  Notice Requirements.  All notices required or permitted by this Lease
shall be in writing and may be delivered in person (by and or by courier) or may
be sent by regular, certified or registered mail or U.S. Postal Service Express
Mail, with postage prepaid, or by facsimile transmission, and shall be deemed
sufficiently given if served in a manner specified in this Paragraph 23.  The
addresses noted adjacent to a Party's signature on this Lease shall be that
Party's address for delivery or mailing of notices.  Either Party may by written
notice to the other specify a different address for notice, except that upon
Lessee's taking possession of the Premises, the Premises shall constitute
Lessee's address for notice.  A copy of all notices to Lessor shall be
concurrently transmitted to such party or parties at such addresses as Lessor
may from time to time hereafter designate in writing.

     23.2  Date of Notice.  Any notice sent by registered or certified mail,
return receipt requested, shall be deemed given on the date of delivery shown on
the receipt card, or if no delivery date is shown, the postmark thereon.  If
sent by regular mail, the notice shall be deemed given forty-eight (48) hours
after the same is addressed as required herein and mailed with postage prepaid.
Notices delivered by United States Express Mail or overnight courier that
guarantee next day delivery shall be deemed given twenty-four (24) hours after
delivery of the same to the Postal Service or courier.  Notices transmitted by
facsimile transmission or similar means shall be deemed delivered upon telephone
confirmation of receipt, provided a copy is also delivered via delivery or mail.
If notice is received on a Saturday, Sunday or legal holiday, it shall be deemed
received on the next business day.

24.  Waivers.  No waiver by Lessor of the Default or Breach of any term,
covenant or condition hereof by Lessee, shall be deemed a waiver of any other
term, covenant or condition hereof, or of any subsequent Default or Breach by
Lessee of the same or of any other term, covenant or condition hereof.  Lessor's
consent to, or approval of, any act shall not be deemed to render unnecessary
the obtaining of Lessor's consent to, or approval of, any subsequent or similar
act by Lessee, or be construed as the basis of an estoppel to enforce the
provision or provisions of this Lease requiring such consent.  The acceptance of
Rent by Lessor shall not be a waiver of any Default or Breach by Lessee.  Any
payment made by Lessee may be accepted by Lessor on account of moneys or damages
due Lessor, notwithstanding any qualifying statements or conditions made by
Lessee in connection therewith, which such statements and/or conditions

                                       28
<PAGE>

shall be of no force or effect whatsoever unless specifically agreed to in
writing by Lessor at or before the time of deposit of such payment.

25.  Recording.  Either Lessor nor Lessee shall, upon request of the other,
execute, acknowledge and deliver to the other a short form memorandum of this
Lease for recording purposes.  The Party requesting recordation shall be
responsible for payment of any fees applicable thereto.

26.  No Right to Holdover.  Lessee has no right to retain possession of the
Premises or any part thereof beyond the expiration or termination of this Lease.
In the event that Lessee holds over, then the Base Rent shall be increased to
one hundred fifty percent (150%) of the Base Rent applicable during the month
immediately preceding the expiration or termination.  Nothing Contained herein
shall be construed as consent by Lessor to any holding over by Lessee.

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; Construction of Agreement.  All provisions of
this Lease to be observed or performed by Lessee are both covenants and
conditions.  In construing this Lease, all headings and titles are for the
convenience of the parties only and shall not be considered a part of this
Lease.  Whenever required by the context, the singular shall include the plural
and vice versa.  This Lease shall not be construed as if prepared by one of the
parties, but rather according to its fair meaning as a whole, as if both parties
had prepared it.

29.  Binding Effect; Choice of Law.  This Lease shall be binding upon the
parties, their personal representatives, successors and assigns and be governed
by the laws of the State in which the Premises are located.  Any litigation
between the Parties hereto concerning this Lease shall be initiated in the
county in which the Premises are located.

30.  Subordination; Attornment; Non-Disturbance.

     30.1  Subordination.  This Lease and any Option granted hereby shall be
subject and subordinate to any ground lease, mortgage, deed of trust, or other
hypothecation or security device (collectively, "Security Device"), now or
hereafter placed upon the Premises, to any and all advances made on the security
thereof, and to all renewals, modifications, and extensions thereof.  Lessee
agrees that the holders of any such Security Devices (in this Lease together
referred to as "Lessor's Lender") shall have no liability or obligation to
perform any of the obligations of Lessor under this Lease.  Any Lender may elect
to have this Lease and/or any Option granted hereby superior to the lien of its
Security Device by giving written notice thereof to Lessee, whereupon this Lease
and such Options shall be deemed prior to such Security Device, notwithstanding
the relative dates of the documentation or recordation thereof.

     30.2  Attornment.  Subject to the non-disturbance provisions of Paragraph
30.3, Lessee agrees to attorn to a Lender or any other party who acquires
ownership of the Premises by reason of a foreclosure of a Security Device, and
that in the event of such foreclosure, such new owner shall not: (i) be liable
for any act or omission of any prior lessor or with respect to events

                                       29
<PAGE>

occurring prior to acquisition of ownership; (ii) be subject to any offsets or
defenses which Lessee might have against any prior lessor, or (iii) be bound by
prepayment of more than one (1) month's rent.

     30.3  Non-Disturbance.  With respect to Security Devices entered into by
Lessor after the execution of this Lease, Lessee's subordination of this Lease
shall be subject to receiving a commercially reasonable non-disturbance
agreement (a "Non-Disturbance Agreement") from the Lender which Non-Disturbance
Agreement provides that Lessee's possession of the Premises and this Lease,
including any options to extend the term hereof, will not be disturbed so long
as Lessee is not in Breach hereof and attorns to the record owner of the
Premises.  Further, within sixty (60) days after the execution of this Lease,
Lessor shall use its commercially reasonable efforts to obtain a Non-Disturbance
Agreement from the holder of any pre-existing Security Device which is secured
by the Premises.  In the event that Lessor is unable to provide the Non-
Disturbance Agreement within said sixty (60) days, then Lessee may, at Lessee's
option, directly contact Lessor's lender and attempt to negotiate for the
execution and delivery of a Non-Disturbance Agreement.

     30.4  Self-Executing.  The agreements contained in this Paragraph 30 shall
be effective without the execution of any further documents; provided, however,
that, upon written request from Lessor or a Lender in connection with a sale,
financing or refinancing of the Premises, Lessee and Lessor shall execute such
further writings as may be reasonably required to separately document any such
subordination or non-subordination, attornment and/or Non-Disturbance Agreement
provided for herein.

31.  Attorney's Fees.  If any Party or Broker brings an action or proceeding
involving the Premises to enforce the terms hereof or declare rights hereunder,
the Prevailing Party (as hereafter defined) in such proceeding, action, or
appeal thereon, shall be entitled to reasonable attorney's fees.  Such fees may
be awarded in the same suit or recovered in a separate suit, whether or not such
action or proceeding is pursued to decision or judgment.  The term, "Prevailing
Party" shall include, without limitation, a Party or Broker who substantially
obtains or defeats the relief sought, as the case may be, whether by compromise,
settlement, judgment or the abandonment by the other Party or Broker of its
claim or defense.  The attorney's fees award shall not be computed in accordance
with any court fee schedule, but shall be such as to fully reimburse all
attorney's fees reasonably incurred.  In addition, Lessor shall be entitled to
attorney's fees, costs and expenses incurred in the preparation and service of
notices of Default and consultations in connection therewith, whether or not a
legal action is subsequently commenced in connection with such Default or
resulting Breach.

32.  Lessor's Access; Showing Premises; Repairs.  Lessor and Lessor's agents
shall have the right to enter the Premises at any time, in the case of an
emergency, and otherwise at reasonable times for the purpose of showing the same
to prospective purchasers, lenders or lessees, and making such alterations,
repairs, improvements or additions to the Premises as Lessor may deem necessary.
All such activities shall be without abatement of rent or liability to Lessee.
Lessor may at any time place on the Premises any ordinary "For Sale" signs and
Lessor may during the last six (6) months of the term hereof place on the
Premises any ordinary "For

                                       30
<PAGE>

Lease" signs. Lessee may at any time place on or about the Premises any ordinary
"For Sublease" sign.

33.  Auctions.  Lessee shall not conduct, nor permit to be conducted, any
auction upon the Premises without Lessor's prior written consent.  Lessor shall
not be obligated to exercise any standard of reasonableness in determining
whether to permit an auction.

34.  Signs.  Except for ordinary "For Sublease" signs, Lessee shall not place
any sign upon the Premises without Lessor's prior written consent.  All signs
must comply with all Applicable Requirements.

35.  Termination; Merger.  Unless specifically stated otherwise in writing by
Lessor, the voluntary or other surrender of this Lease by Lessee, the mutual
termination or cancellation hereof, or a termination hereof by Lessor for Breach
by Lessee, shall automatically terminate any sublease or lesser estate in the
Premises; provided, however, that lessor may elect to continue any one or all
existing subtenancies.  Lessor's failure within ten (10) days following any such
event to elect to the contrary by written notice to the holder of any such
lesser interest, shall constitute Lessor's election to have such event
constitute the termination of such interest.

36.  Consents.  Except as otherwise provided herein, wherever in this Lease the
consent of a Party is required to an act by or for the other Party, such consent
shall not be unreasonably withheld or delayed.  Lessor's actual reasonable costs
and expenses (including but not limited to architects', attorneys', engineers'
and other consultants' fees) incurred in the consideration of, or response to, a
request by Lessee for any Lessor consent, including but not limited to consents
to an assignment, a subletting or the presence or use of a Hazardous Substance,
shall be paid by Lessee upon receipt of an invoice and supporting documentation
therefor.  Lessor's consent to any act, assignment or subletting shall not
constitute an acknowledgment that no Default or Breach by Lessee of this Lease
exists, nor shall such consent be deemed a waiver of any then existing Default
or Breach, except as may be otherwise specifically stated in writing by Lessor
at the time of such consent.  The failure to specify herein any particular
condition to Lessor's consent shall not preclude the imposition by Lessor at the
time of consent of such further or other conditions as are then reasonable with
reference to the particular matter for which consent is being given.  In the
event that either Party disagrees with any determination made by the other
hereunder and reasonably requests the reasons for such determination, the
determining party shall furnish its reasons in writing and in reasonable detail
within ten (10) business days following such request.

37.  Guarantor.

     37.1  Execution.  The Guarantors, if any, shall each execute a guaranty in
the form most recently published by the American Industrial Real Estate
Association, and each such Guarantor shall have the same obligations as Lessee
under this Lease.

     37.2  Default.  It shall constitute a Default of the Lessee if any
Guarantor fails or refuses, upon request to provide: (a) evidence of the
execution of the guaranty, including the authority of the party signing on
Guarantor's behalf to obligate Guarantor, and in the case of a

                                       31
<PAGE>

corporate Guarantor, a certified copy of a resolution of its board of directors
authorizing the making of such guaranty, (b) current financial statements, (c) a
Tenancy Statement, or (d) written confirmation that the guaranty is still in
effect.

38.  Quiet Possession.  Subject to payment by Lessee of the Rent and performance
of all of the covenants, conditions and provisions on Lessee's part to be
observed and performed under this Lease, Lessee shall have quiet possession and
quiet enjoyment of the Premises during the term hereof.

39.  Options.

     39.1  Definition.  "Options" shall mean: (a) the right to extend the term
of or renew this Lease or to extend or renew any lease that Lessee has on other
property of Lessor; (b) the right of first refusal or first offer to lease
either the Premises or other property of Lessor; (c) the right to purchase or
the right of first refusal to purchase the Premises or other property of Lessor.

     39.2  Options Personal To Original Lessee.  Each option granted to Lessee
in this Lease is personal to the original Lessee, and cannot be assigned or
exercised by anyone other than said original Lessee and only while the original
Lessee is in full possession of the Premises and, if requested by Lessor, with
Lessee certifying that Lessee has no intention of thereafter assigning or
subletting.

     39.3  Multiple Options.  In the event that Lessee has any multiple Options
to extend or renew this Lease, a later Option cannot be exercised unless the
prior Options have been validly exercised.

     39.4.  Effect of Default on Options.

     (a) Lessee shall have no right to exercise an Option: (i) during the period
commencing with the giving of any notice of Default and continuing until said
Default is cured, (ii) during the period of time any Rent is unpaid (without
regard to whether notice thereof is given Lessee), (iii) during the time Lessee
is in Breach of this Lease, or (iv) in the event that Lessee has been given
three (3) or more notices of separate Default, whether or not the Defaults are
cured, during the twelve (12) month period immediately preceding the exercise of
the Option.

     (b) The period of time within which an Option may be exercised shall not be
extended or enlarged by reason of Lessee's inability to exercise an Option
because of the provisions of Paragraph 39.4(a).

     (c) An Option shall terminate and be of no further force or effect,
notwithstanding Lessee's due and timely exercise of the Option, if, after such
exercise and prior to the commencement of the extended term, (i) Lessee fails to
pay Rent for a period of thirty (30) days after such Rent becomes due (without
any necessity of Lessor to give notice thereof), (ii) Lessor gives to Lessee
three (3) or more notices of separate Default during any twelve (12) month
period, whether or not the Defaults are cured, or (iii) if Lessee commits a
Breach of this Lease.

                                       32
<PAGE>

40.  Multiple Buildings.  If the premises are a part of a group of buildings
controlled by Lessor, Lessee agrees that it will observe all reasonable rules
and regulations which Lessor may make from time to time for the management,
safety, and care of said properties, including the care and cleanliness of the
grounds and including the parking, loading and unloading of vehicles, and that
Lessee will pay its fair share of common expenses incurred in connection
therewith.

41.  Security Measures.  Lessee hereby acknowledges that the rental payable to
Lessor hereunder does not include the cost of guard service or other security
measures, and that Lessor shall have no obligation whatsoever to provide same.
Lessee assumes all responsibility for the protection of the Premises, Lessee,
its agents and invitees and their property from the acts of third parties.

42.  Reservations.  Lessor reserves to itself the right, from time to time, to
grant, without the consent or joinder of Lessee, such easements, rights and
dedications that Lessor deems necessary, and to cause the recordation of parcel
maps and restrictions, so long as such easements, rights, dedications, maps and
restrictions do not unreasonably interfere with the use of the Premises by
Lessee.  Lessee agrees to sign any documents reasonably requested by Lessor to
effectuate any such easement rights, dedication, map or restrictions.

43.  Performance Under Protest.  If at any time a dispute shall arise as to any
amount or sum of money to be paid by one Party to the other under the provisions
hereof, the Party against whom the obligation to pay the money is asserted shall
have the right to make payment "under protest" and such payment shall not be
regarded as a voluntary payment and there shall survive the right on the part of
said Party to institute suit for recovery of such sum.  If it shall be adjudged
that there was no legal obligation on the part of said Party to pay such sum or
any part thereof, said Party shall be entitled to recover such sum or so much
thereof as it was not legally required to pay.

44.  Authority.  If either Party hereto is a corporation, trust, limited
liability company, partnership, or similar entity, each individual executing
this Lease on behalf of such entity represents and warrants that he or she is
duly authorized to execute and deliver this Lease on its behalf.  Each party
shall, within thirty (30) days after request, deliver to the other party
satisfactory evidence of such authority.

45.  Conflict.  Any conflict between the printed provisions of this Lease and
the typewritten or handwritten provisions shall be controlled by the typewritten
or handwritten provisions.

46.  Offer.  Preparation of this Lease by either Party or their agent and
submission of same to the other Party shall not be deemed an offer to lease to
the other Party.  This Lease is not intended to be binding until executed and
delivered by all Parties hereto.

47.  Amendments.  This Lease may be modified only in writing, signed by the
Parties in interest at the time of the modification.  As long as they do not
materially change Lessee's obligations hereunder, Lessee agrees to make such
reasonable non-monetary modifications to this Lease as may be reasonably
required by a Lender in connection with the obtaining of normal financing or
refinancing of the Premises.

                                       33

48.  Multiple Parties.  If more than one person or entity is named herein as

                  ADDENDUM TO STANDARD INDUSTRIAL/COMMERCIAL

                     SINGLE TENANT LEASE-NET (AIREA 1997)

     This Addendum is made as of May 29, 1997 by and between Braden Court
Associates, a California general partnership ("Lessor") and IMPCO Technologies,
Inc., a Delaware corporation ("Lessee") and with respect to the Standard
Industrial/Commercial Single Tenant Lease - Net (American Industrial Real Estate
Association (1997)) between Lessor and Lessee dated concurrently herewith
("AIREA Lease"). To the extent that the provisions of this Addendum are
inconsistent with the terms and conditions of the AIREA Lease, such
inconsistencies shall take priority according to the following order: (i)
printed or written inserts to this Addendum, (ii) typed, printed or written
inserts to the AIREA Lease, (iii) This Addendum, and (iv) the printed form AIREA
Lease. All capitalized terms not otherwise defined herein shall have the meaning
set forth in the AIREA Lease.

     1.2  Premises.  The Premises consist of a building containing approximately
64,680 square feet located at 25242 Arctic Ocean Drive, Lake Forest, California
92630 and the improvements ("Improvements") to be constructed thereon pursuant
to (S) 50.

     1.3  Term.  The period commencing on  June 1, 2000 ("Commencement Date")
and ending eight calendar years thereafter.

     1.4  Deleted.

     1.5  Base Rent.  Base rent of $43,141.56 shall be payable commencing July
1, 2000. Lessee shall, however, be responsible for paying common area
maintenance charges of $8,408.40 on June 1, 2000 for the month of June 2000.

     1.6  Deleted.  ___________.

     1.8  Agreed Uses.  Corporate office, warehousing, research and development,
and all other operations incidental to the conduct of such business which are
not in violation of law or covenants, conditions and restrictions of record.

     2.5  Deleted.

     3.5  Option to Extend.

          (a) Lessee shall have one option ("Extension Option") to extend the
Term for a period of 36 months ("Option Term").  The Extension Option must be
exercised by irrevocable notice in writing of such exercise, delivered by Lessee
to Lessor, not later than six (6) months prior to the end of the Term.  The
Extension Option shall terminate automatically upon any termination of the
Lease.  The Base Rent for the Option Term shall be the greater of (i) the Base
Rent in effect at the end of the Term, or (ii) 100% of the "Fair Market Value."
<PAGE>

          (b) Fair Market Value.  The "Fair Market Value" means the then fair
market value being charged for a five-year lease with annual adjustments as set
forth in (S)3.5(c) for similar premises in the vicinity of the Premises for a
renewal tenant ("Vicinity Rents").  In  determining Fair Market Value based on
Vicinity Rents, (A) the parties shall take into consideration, without
limitation:  the cost, if any, of parking; and the comparable age and quality of
the Premises, traffic, access and area amenities; and (B) with respect to the
first Extension Option, the parties shall specifically not take into
consideration and shall not reduce the Fair Market Value because of, any of the
following, if applicable (such benefits having been liquidated by the parties
providing the 5% discount off of Fair Market Value):  free rent concessions
offered in connection with Vicinity Rents; brokerage commissions saved by
Lessor; the absence of any unleased periods of time; moving allowances; tenant
improvements being offered in connection with Vicinity Rents other than painting
and carpeting, it being understood that the Premises will be approximately ten
(10) years old and in good shape and condition.  Lessor and Lessee shall
reasonably and in good faith attempt to agree on the Fair Market Value beginning
not later than three months prior to the commencement of the applicable Option
Term.  If the parties are unable to agree upon the Fair Market Value prior
within 30 days thereafter, then within five days thereafter each party, at its
cost and by giving notice to the other party, shall appoint an independent
M.A.I. real estate appraiser with at least five years full-time commercial
appraisal experience in Orange County to determine such Fair Market Value.  If a
party does not appoint an appraiser within such five days after the other party
has given notice of the name of its appraiser, the single appraiser appointed
shall be the sole appraiser and shall set the Fair Market Value.  If there are
two appraisers by the parties in this (S) 3.5(b), they shall meet promptly and
attempt to set the Fair Market Value.  If the two appraisers are unable to agree
within 10 days after the second appraiser has been appointed, they shall attempt
to elect a third appraiser meeting the above qualifications within 10 days after
the last day the two appraisers are given to set the Fair Market Value.  If the
two appraisers are unable to agree on the third appraiser, either of the parties
to this Lease, by giving 10 days' notice to the other party, can apply to the
then president of the Orange County Real Estate Board, or to the presiding judge
of the Superior Court of Orange County, for the selection of a third appraiser
meeting the qualifications stated in this section.  Each of the parties shall
bear one-half of the cost of appointing the third appraiser and of paying the
third appraiser's fee.  The third appraiser, however selected, shall be a person
who has not previously acted in any capacity for either party.  Within 15 days
after the selection of the third appraiser, a majority of the appraisers shall
set the Fair Market Value after having been instructed to comply with the
provisions of (A) and (B) above.  If a majority of the appraisers are unable to
set the Fair Market Value, the Fair Market Value shall be the average of the two
closets appraisals (unless the appraisal are equidistant, in which case, the
middle appraisal shall be the Fair Market Value).

          (c) Option Term CPI Adjustments.  During the Option Term, the Base
Rent (and the corresponding Monthly Installments of the Base Rent) determined in
accordance with (S)3.5(b), shall be adjusted each 24 months (the "Adjustment
Date"), commencing on the second anniversary of the commencement of such Option
Term.  Adjustments, if any, shall be based upon increases (if any) in the Index.
The Index in publication three months before such Option Term commencement shall
be the "Base
<PAGE>

Index." The Index in publication three months before each Adjustment Date shall
be the "Comparison Index." As of each Adjustment Date, the Base Rent payable
during the ensuing 24-month period shall be determined by increasing the initial
Base Rent by a percentage equal to the percentage increase, if any, in the
Comparison Index over the Base Index, provided that such increased Base Rent
shall not be less than 106.09% nor more than 112.6% of the Base Rent for the
prior 24-month period. When the Base Rent payable as of each Adjustment Date is
determined, Lessor shall promptly give Lessee written notice of such adjusted
Base Rent and the manner in which it was computed. Upon Lessor's request, Lessee
shall execute an amended Commencement Date Memorandum in the form of Exhibit A
after each such adjustment. The Base Rent as so adjusted from time to time shall
be the "Base Rent" for all purposes under this Lease. If at any Adjustment Date
the Index no longer exists in the form described in this Lease, Lessor may
substitute any substantially equivalent official index published by the Bureau
of Labor Statistics of its successor. Lessor shall use any appropriate
conversion factors to accomplish such substitution. The substitute index shall
then become the "Index" hereunder.

          (d) Effect of Default on Options.  The Extension Option may be
exercised by Lessee during any uncured Lessee defaults, and the period for
exercise shall not be extended for any cure periods.

          4.1.1  Rent.  The term "Rent" means each and every payment required to
be made by Lessee pursuant to this Lease including without limitation Base Rent,
utilities, taxes, insurance premiums, late charges and interest and utility
charges, repairs and maintenance incurred by Lessor on Lessee's behalf.  All
Rent shall be paid when due and without notice except as expressly provided to
the contrary in this Lease.  All Rent constitutes "rent" or "rental" under the
unlawful detainer statutes (CCP (S)1161 et seq.).

     4.3  CPI.  The Base Rent shall adjust as set forth herein on the beginning
of the 21st month, and each 24 months thereafter, following the Commencement
Date.  On each adjustment date, the Base Rent shall be increased, but not
decreased, to a sum equal to the initial Base Rent multiplied by a fraction, the
numerator of which is the Index for the third calendar month prior to the
adjustment date and the denominator of which is the Index for the third calendar
month prior to the Commencement Date.  Notwithstanding the foregoing, the
increased base Rent on each adjustment date shall be not less than 106.09% nor
more than 112.36% of the prior Base Rent.  The "Index" means the consumer Price
Index - All Urban Consumers (Los Angeles-Riverside-Orange County Area; Base
Period 1982-84 = 100), as published by the United States Department of Labor,
Bureau of Labor Statistics.  Should the Bureau discontinue the publication of
the Index, or publish the same less frequently, or alter the same in some other
manner than Lessor and Lessee shall adopt a substitute index or procedure which
is mot similar to the Index (as of the date of Execution of this Lease) in
reflecting consumer prices.

     4.4  Operating Expenses

          (a) Lessee shall pay to Lessor, as hereinafter provided, Lessee's
Share of "Operating Expenses," as defined in paragraph 4.4(e) below.  "Lessee
Share" is
<PAGE>

42.32% for Real Property Taxes and any other Operating Expenses attributable
solely to the lot on which the Premises are located, computed by dividing the
number of square feet of the floor area of the Premises (64,680 square feet) by
the total number of square feet of the floor area of buildings built, or to be
built, on the lot on which the Premises are located (152,824 square feet).
"Lessee's Share" is 22.09% for Operating Expenses other than Real Property Taxes
and any other Operating Expenses attributable solely to the lot on which the
Premises are located, computed by dividing the number of square feet of the
floor area of the Premises (64,680 square feet) by the total number of square
feet of the floor area of all buildings built, or to be built, in the Industrial
Center of which the premises are a part (292,824 square feet). After completion
of construction Lessee's Share may be adjusted based on actual square footage of
the floor space of the buildings in the Industrial Center as built.
Notwithstanding the above in no event shall Lessee's Share for Real Property
Taxes and any other Operating Expenses attributable solely to the lot on which
the Premises are located exceed 43.32% or shall Lessee's Share for Operating
Expenses other than Real Property Taxes and any other Operating Expenses
attributable solely to the lot on which the Premises are located exceed 23.09%;
except that if Lessor elects to sell a portion, but not all, of the Industrial
Center, then Lessee's Share shall be proportionately adjusted upward without
limitation, provided that the total Operating Expenses allocated to Lessee per
Square Foot shall not be increased as a result of such sale over market rates
for operating expense pass-throughs for similar projects having at least 290,000
Square Feet.

          (b) On or about the commencement of each calendar year, Lessor shall
send to Lessee a written estimate of Lessee's Share of Operating Expenses for
such calendar year.  Lessee shall pay its estimated share of Operating Expenses
in equal monthly installments, in advance, on or before the first day of each
month.  Within ninety (90) days after the end of each calendar year (or such
shorter interval as Lessor shall select), Lessor shall furnish to Lessee a
statement showing in reasonable detail the actual operating expenses for the
Industrial Center incurred for the prior calendar years, and the parties shall,
within thirty (30) days thereafter, make payment or allowance as necessary to
adjust Lessee's estimated payments to the actual Lessee's Share of Operating
Expenses as shown by the applicable periodic statements submitted to Lessee by
Lessor.

          (c) If Lessor shall determine at any time or from time to time that
the estimate of Lessee's Share of Operating Expenses for the current calendar
year is or will become inadequate to meet Lessee's Share of such Operating
Expenses for any reason, Lessor shall immediately determine the appropriate
amount of such inadequacy and issue a supplemental estimate as to Lessee's Share
of Operating Expenses along with Lessor's calculations showing the actual or
potential inadequacy, and Lessee shall pay such increase in the estimated
Lessee's Share of Operating Expenses as reflected by such supplemental estimate.

          (d) Lessor shall keep or cause to be kept separate and complete books
of accounting covering costs and expenses of operating maintaining the Common
Area and other portions of the Industrial Center which Lessor is required to
maintain and repair and showing the method of calculating Lessee's Share of
Operating Expenses and shall preserve for at least twelve (12) months after the
close of each fiscal year all vouchers,
<PAGE>

invoices, statements or payroll records, and other papers evidencing said costs
and expenses for that calendar year. Lessee, through any certified public
accountant designated by it, shall have the right to examine or audit the books
and other documents evidencing such costs and expenses for the previous calendar
year, during reasonable business hours and not more frequently than once during
any calendar year.

          (e) The term "Operating Expenses" as used herein shall mean all Real
Property Taxes and reasonable Common Area costs and expenses incurred in
connection with the maintenance, repair and operation of the Industrial Center.
Operating Expenses shall include, without limitation:  (i) sweeping and
maintenance services; (ii) repairs to and replacement of asphalt paving,
bumpers, striping; (iii) light bulbs, light standards and lighting systems; (iv)
guard and directional signs, planters, landscaping and sprinkler systems and
services in planting areas; (v) water, electrical and other utility services;
(vi) removal of trash, rubbish and other refuse from the Common Areas only
(trash removal from Premises shall be paid by the tenant directly and shall not
be an Operating Expense); (vii) cleaning of and replacement of signs of the
Industrial Center, including revamping and repairs made as required; (viii)
maintenance of all the Common Area from any obstructions not reasonably required
for the Common Area uses, including the prohibition of the sale or display of
merchandise or the storing of materials or equipment in the Common Area, payment
of all electrical, water and other utility charges or fees for services
furnished to Common Area; (ix) the amount of Real Property Taxes paid by Lessor
under (S) 10 of this Lease; (x) establishment of reasonable reserves for
replacement or repair of Common Area improvements, equipment and supplies; (xi)
costs of compliance with law, rule, regulations enacted or adopted after the
date of this Lease; (xii) employment of such personnel as Lessor may deem
reasonably necessary, if any, to direct parking and police the Common Area and
facilities; (xiii) employment of personnel used in connection with the
operation, maintenance and repair of the Common Area including payment or
provision for unemployment insurance, workers' compensation insurance and other
employee costs; (xiv) any other items reasonably necessary from time to time to
properly repair, replace, maintain and operate the Common Area within the
Industrial Center, including without limitation association dues under
covenants, conditions and restrictions of record from time to time; (xv) the
cost of all premiums paid and deductibles actually incurred for Common Area
liability insurance and Common Area improvements casualty insurance, with
coverage as specified in but only to the extent that such insurance is customary
and reasonable; (xvi) a management fee equal to 3% of Operating Expenses to
cover Lessor's management, overhead and administrative expenses; and (xvii) if
any expenditure which otherwise qualifies as an Operating Expense (in excess of
prior reserves therefor pursuant to subsection (x)), must be capitalized
pursuant to GAAP or sound accounting practice, then such expenditure shall
nonetheless be an Operating Expense, but shall be amortized in equal monthly
installments with interest thereon at 10% per annum over its reasonably
estimated useful life.  Notwithstanding the above, in no event shall Lessee's
Share of Operating Expenses pursuant to subsections (x) and (xvii) (but
excluding any (S)6.3.3 Operating Expenses) aggregate more than $800 per month,
escalated 5% per annum commencing on the first anniversary of the Commencement
Date.
<PAGE>

     Notwithstanding anything to the contrary, the term "Operating Expenses"
shall specifically exclude any and all of the following:  (1) depreciation or
interest (except pursuant to the prior paragraph); (2) any and all payments for
(A) loan principal or interest, together with expenses thereto related in
connection with such financing or any refinancing during the term of this Lease,
(B) any ground lease rent or (C) similar payments; (3) any and all of Lessor's
income, excise, franchise taxes, as well as any and all taxes (excepting those
provided for in (S)10) which do not uniquely pertain to the Premises and
Lessee's specific use thereof; (4) any and all operating expenses allocable to
services rendered to specific tenants other than Lessee and which do not benefit
Lessee; (5) except as specifically provided in the prior paragraph, salaries of
Lessor's employees who are not engaged in the day-to-day management and
maintenance of the Premises, including, without limitation, the salaries of
employees who are executive managers, accountants, bookkeepers, receptionists,
clerks, marketing representatives, administrative assistants, secretaries and
brokers; (6) any and all costs to compel full performance under leases with all
prior, existing and prospective tenants at the Industrial Center, including,
without limitation, all legal fees, costs and expenses to collect rent in
arrears and recover possession; (7) any and all costs to lease space in the
Industrial Center to all prior, existing and prospective tenants, including,
without limitation, consulting and marketing fees, advertising expenses,
brokerage commissions, legal fees, vacancy costs, rent or other rent concessions
and/or refurbishment or improvements expenses; (8) costs to correct original
construction defects; (9) any repair or other work necessitated by condemnation,
fire or other casualty (except for uninsured or deductible losses to the Common
Area); (10) except for subsections (xiii) and (xvi) above, costs exceeding those
obtainable through competitive bidding; and (11) costs, and the like due to
Lessor's violation of any governmental rule or authority.

          (f) Lessee's failure to pay timely and of the charges in connection
with the performance of its obligations to be paid under this (S)4.4 shall
constitute a material default under this Lease.

          (g) The inclusion of the improvements, facilities and services set
forth in the definition of Operating Expenses shall not be deemed to impose an
obligation on Lessor either to have such improvements or facilities or to
provide those services unless the Industrial Center 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, or Lessee actually pays for any such
improvements, facilities or services as part of Lessee's Share of Operating
Expenses.

          6.1.1  Notwithstanding anything to the contrary contained herein,
Lessor represents and warrants that the Premises may be legally used for the
Agreed Uses under all applicable laws, codes, ordinances, rules and regulations
and, including without limitation, applicable building, zoning, environmental
and land use ordinances.  Lessor warrants and represents to Lessee that (i)
Lessor has full right and power to enter into this Lease and to lease the
Premises as provided herein and to carry out all of its obligations pursuant to
this Lease, (ii) Lessor is financially capable of performing and satisfying its
full obligations under this Lease, and (iii) Lessor owns the premises in fee
simple.
<PAGE>

     6.2(h)  Lessor shall protect, defend (by legal counsel reasonably
acceptable to Lessee), indemnify and hold harmless Lessee from and against any
and all liabilities, obligations, claims, damages, fines, penalties, actions,
causes of action (criminal, civil or administrative), investigation, abatement,
containment, remediation, response, monitoring, removal or clean-up costs and
all other costs and expense (including without limitation reasonable
consultants' and attorneys' fees) arising out of or in connection with any
Hazardous Substance deposited or storage tank installed in, on or around the
Premises by Lessor, or its employees, agents or contractors.  This
indemnification is in addition to, and not in lieu of, any other rights of
indemnification, reimbursement and contribution in favor of Lessee against
Lessor provided by statute or common law.

          6.3.1  Lessor warrants and represents to Lessee that, as of the date
of this Lease, Lessor has not received from any agency having jurisdiction or
from any insurer, any notice that a violation of any Applicable Law exists with
respect to the premises, and that on the commencement Date the Premises will be
in compliance with all Applicable Laws.

          6.3.2  "Applicable Laws" include without limitation:  (i) any future
laws enacted or first made applicable after the date hereof; and (ii) any
federal, state or local law, ordinance, regulation or guideline regulating or
imposing liability or standards of conduct concerning any Hazardous Substances;
including without limitation the Comprehensive Environmental Response,

Hazardous Waste Control Law (Division 20, Chapter 6.5 of the California Health
and Safety code (S)25300 et seq.; Division 20, Chapter 6.95 (Hazardous Materials
Release Response Plans and Inventory) of the California Health and Safety Code;
(S)25281 of the California Health and Safety Code, Division 20, Chapter 6.7
(underground Storage of Hazardous Substances); and any other federal, state or
local laws or regulations adopted and publications promulgated pursuant to said
laws or relating to Hazardous Materials.

          6.3.3  Future Laws.  With respect to any laws enacted after the
                 -----------
Commencement Date and requiring modification, alteration or betterment to or of
the Premises or the common Area, including, without limitation, building codes,
the ADA and environmental protection laws and laws requiring installation of
monitoring equipment measuring air, soil or groundwater quality or extraordinary
waste disposal facilities or equipment or modifications to existing waste
treatment facilities and equipment, Lessor and Lessee shall allocate the costs
thereof ("Compliance Costs") as follows.  Lessee shall pay the Compliance Cost
if it relates to or arises in connection with any particular use of the Premises
by Lessee (as opposed to industrial/warehouse uses in general).  Lessor shall
pay the Compliance Cost if:
<PAGE>

                 (i)   it relates to any law in effect on the Commencement Date;
     or

                 (ii)  it relates to the Premises (except as provided in the
     prior sentence) or the Industrial Center as a whole; provided that (A) if
     such Compliance Cost relates exclusively to the Premises (but is not
     applicable to other Industrial Center buildings), then the Base Rent shall
     be increased by the Compliance Cost amortized with interest at 10% over its
     estimated useful life; and (B) otherwise the Compliance Cost shall be an
     Operating Expense.

     7.1(c)  Lessor estimates in good faith, based on the information reasonably
available to it, that Operating Expenses for the Premises for the year 2000 will
be approximately $.13 per month per square foot of Building Area, including
property taxes (including Mello-Roos), insurance, maintenance, association fees
and reserves.  Lessee agrees that this estimate is not binding on Lessor and
that Lessee will not rely on it as an indication of what any actual operating
costs will be, either for the year 2000 or for any other period.

     7.1(d)  Lessee shall also contract and pay for all trash removal generated
by Lessee or from the Premises.

          7.2.1. Notwithstanding (S)7.2, Lessee's obligation to repair shall
not extend to:

                 (i)   damage and repairs caused or necessitated by Lessor or
     their employees, agents, or contractors (but not damages caused by other
     tenants);

                 (ii)  reasonable wear and rear;

                 (iii) damages arising from Lessor's failure to comply with the
     provisions of this Lease;

                 (iv)  repairs necessitated by a requirement to comply with laws
     in effect on or before the Commencement Date;

                 (v)   repairs to structural portions of the Premises;

                 (vi)  roof and roof membrane repair and maintenance, which
     shall be performed by Lessor and the cost of which shall be an Operating
     Expense; and

                 (vii) repairs necessitated by a taking by eminent domain.

     7.4(a).  Lease (S)7.4(a) is deleted in its entirety an replaced by the
following:

     Lessee shall own all Utility Installations (defined in (S)7.3(a)) installed
by Lessee and Alterations located in the research and development, warehouse and
emission lab portions of the Premises, and all Trade Fixtures.  Lessor shall own
all Utility
<PAGE>

Installations, Alterations and all Lessee Owned Utility Installations and
Alterations located in the office portion of the Premises, subject to the right
of Lessor to require their removal pursuant to (S)7.4(iii).

     7.4(b).  Lease (S)7.4(b) is deleted in its entirety and replaced by the
following:

          (i) Prior to the expiration of the Term, or within 30 days after any
earlier Lease termination, Lessee shall remove, at its expense, any Lessee Owned
Utility Installations and Lessee Owned Alterations required to be removed by
Lessor.  All damage and repairs necessitated by such removal shall be repaired
by Lessee in a manner such that all portions of the Premises remain fully
operational.

         (ii) Prior to the expiration of the Term, or within 30 days after an
earlier Lease termination, Lessee shall remove, at its expense, all Trade
Fixtures required to be removed by Lessor.  All damage and repairs necessitated
by such removal shall be repaired by Lessee in a manner such that all portions
of the Premises remain fully operational.

     7.5  Common Areas

          (a) Definition.  The term "Common Areas" is defined as all areas and
facilities outside the Premises and within the exterior boundary line of the
Industrial Center that are provided and designated by the Lessor from time to
time for the general non-exclusive use of Lessor, Lessee and of other lessees of
the Industrial Center and their respective employees, suppliers, shippers,
customers and invitees, including parking areas, loading and unloading areas,
trash areas, roadways, sidewalks, walkways, parkways, driveways and landscaped
areas.

          (b) Lessee's rights.  Lessor shall maintain the Common Areas in good
repair and in a clean and neat condition at all times.  Lessor hereby grants to
Lessee, for the benefit of Lessee and its employees, suppliers, shippers,
customers and invitees, during the term of this Lease, the nonexclusive right to
use, in common with others entitled to such use, the Common Areas as they exist
from time to time, subject to any rights, powers, and privileges reserved by
Lessor under the terms hereof or under the terms of the rules and regulations or
restrictions governing the use of the Industrial Center in the form of Exhibit
E, and as reasonably amended from time to time ("Rules").  Under no
circumstances shall the right herein granted to use the Common Areas be deemed
to include the right to store any property, temporarily or permanently, in the
Common Areas.  Any such storage shall be permitted only by the prior written
consent of Lessor or Lessor's designated agent, which consent may be revoked at
any time.  In the event that any unauthorized storage shall occur then Lessor
shall have the right, upon 48 hours prior written notice, or without notice in
the case of an emergency, in addition to such other rights and remedies that it
may have, to remove the property and charge the cost to Lessee, which cost shall
be immediately payable upon demand by Lessor.

          (c) Rules and Regulations.  Lessor or such other person(s) as Lessor
may appoint shall have the exclusive control and management of the Common Areas
and

<PAGE>

shall have the right, from time to time, to establish, modify, amend and enforce
the Rules. Lessee agrees to abide by and conform to all such Rules, and to cause
its employees, suppliers, shippers, customers, and invitees to so abide and
conform. Notwithstanding such Rules, Lessee and its invitees shall have the
right of access to the Premises and the parking lot seven days per week, 24
hours per day. Lessor shall use commercially reasonable efforts to enforce the
Rules against all Industrial Center tenants on a non-discriminatory bases
(provided that in no event shall Lessor be obligated to terminate a lease in
order to so enforce), but shall not be responsible to Lessee for the non-
compliance with the rules by other lessees of the Industrial Center.

          (d) Changes.  To the extent that Lessee's use, access to and enjoyment
of the Premises are not materially impaired, Lessor shall have the right, in
Lessor's sole, good faith 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; (c) to
designate other land outside the boundaries of the Industrial Center 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 Industrial Center, or any portion
thereof; and (f) to do and perform such other acts and make such other changes
in, to or with respect to the Common Areas and Industrial Center as Lessor may,
in the exercise of sound business judgment, deem to be appropriate.

          (e) Parking.  Lessee shall have the right to 160 parking spaces in the
Common Area, on an unreserved, non-exclusive basis.  Although Lessee
acknowledges and agrees that all Industrial Center parking is non-exclusive, if
other tenants in the Industrial Center begin parking in and around the Premises,
Lessor shall allow Lessee at its expense to stencil on the space bumpers "IMPCO
Technologies Parking" on the approximately 54 parking spaces bordering the
Premises and across from the north side of the Premises, provided that Lessee
shall remove all such signage upon (i) termination of the Lease or (ii)
irreconcilable complaints by other Industrial Center tenants.

8.  Insurance.  All references to "$2,000,000" shall be subject to periodic
increase, as reasonably requested by Lessor's lenders from time to time.

     8.6  is deleted and replaced by the following:

     Waiver of Subrogation.  Lessee and Lessor each hereby release and relieve
     the other, and waive their right of recovery against the other, up to the
     extent of applicable insurance proceeds, for loss or damage arising out of
     or incident to the perils insured against under this Lease which perils
     occur in, on or about the Premises, whether due to the negligence of Lessor
     or Lessee or their agents, employees, contractors and/or invitees.  Lessee
     and Lessor shall, upon obtaining the policies of insurance required
     hereunder, give notice to the insurance carrier

<PAGE>

     or carriers that the foregoing mutual waiver of subrogation is contained in
     this Lease.

          8.7.1  Except to the extent provided in (S)8.8, which (S)8.8 shall
prevail over this (S)8.7.1, Lessor shall indemnify, defend and hold Lessee, its
directors, officers, agents and employees, harmless from and against any and all
claims, causes of action, liabilities, damages, costs, losses and expenses
(including, but not limited to, reasonable consultants' and attorneys' fees),
which may be imposed upon, incurred by or asserted in connection with any third
party claims brought against Lessee or any of Lessee's directors, officers,
agents or employees, arising, directly or indirectly, out of, or in connection
with the willful misconduct of Lessor or the negligent acts or negligent
omissions of Lessor or Lessor's agents or employees.  Lessor, upon notice from
Lessee, shall defend the same at Lessor's expense by counsel reasonably
satisfactory to Lessee, and Lessee shall cooperate with Lessor in such defense.
Lessee need not have first paid any claim in order to be so indemnified.

     8.9  Casualty Insurance Coverage.  This (S)8.9 shall govern over the third
sentence of (S)8.3(a) and the first sentence of (S)8.4.  Lessor's Premises
casualty insurance shall over and insure all Utility Installations and
Alterations excluding (i) those owned by Lessee pursuant to (S)7.4, and (ii)
those installed by Lessee unless Lessee gives Lessor not less than 30 days prior
written notice thereof.  Lessee shall insure in accordance with (S)8.4 all
Utility Installations and Alterations not required to be covered by Lessor's
insurance pursuant to the prior sentence.

          9.1.1  When repair or replacement is required under this (S)9, such
repair or replacement shall be commenced within a reasonable period of time
after receipt of insurance proceeds therefor and thereafter completed with all
due diligence.

          10.1.1  Notwithstanding (S)10.1, "Real Property Taxes" shall not
include taxes on rents, gross receipts or revenues of Lessor from the Premises
or Industrial Center, all or which shall be Lessor's obligation.

     10.2(a) and (b) are deleted.  Lessee shall pay Lessor for Real Property
Taxes as part of Operating Expenses, as provided in (S)4.4.

     12.1(f)  Assignment to Affiliates.  Lessee shall have the right to assign
the Lease to any Affiliate without Lessor's consent.  "Affiliate" means any
entity controlling, controlled by or under common control with Lessee, and any
entity acquiring (by way of purchase, merger or consolidation) all or
substantially all of the assets of Lessee.  The sale of shares in the initial,
registered, interstate public offering by Lessee shall not constitute an
assignment for which Lessor's consent is required.

     12.4  Sublease or Assignment Profits.  Lessor shall be entitled to all
"Profits" from the assignment or sublease of any or all of the Premises.
Profits shall equal (i) the sum of all consideration received by Lessee from
such sublessee or assignee for or relating to the Premises, less (ii) direct,
out-of-pocket costs incurred in effecting such

<PAGE>

sublease or assignment. Lessee shall provide all information reasonably
requested by Lessor relating to the determination of such profits.

     13.1(g)  Deleted.

     13.2(e)  Other Lessor Remedies.  The parties expressly acknowledge that
(S)13.2(a)(iii) is intended to comply with California Civil Code
(S)1951.2(c)(1).  Lessor has the remedy described in California Civil Code
(S)1951.4 (Lessor may continue the Lease in effect after Lessee's breach and
abandonment and recover rent as it becomes due), and Lessee expressly agrees and
acknowledges that any and all limitations in this Lease to Lessee's sublease and
assignment rights are reasonable.

     In any action of unlawful detainer commenced by Lessor against Lessee by
reason of any default hereunder, Lessee acknowledges that the monthly fair
rental value of the Premises for the period of the unlawful detainer shall be
not less than the amount of monthly Base Rent, plus one twelfth of all
additional Rental paid during the most recent calendar year.

     Lessee hereby waives any right of redemption or relief from forfeiture
under any present of future law, if Lessee is evicted or Lessor takes possession
of the Premises by reason of any default by Lessee hereunder.  The various
rights and remedies reserved to Lessor herein, including those not specifically
described herein, shall be cumulative, and except as otherwise provided by
statutory law in force and effect at the time of the execution hereof, Lessor
may pursue any or all of such rights and remedies, whether at the same time or
otherwise.  One or more waivers by Lessor of any breach or default shall not be
a waiver of any other breach or default of the same or any other provision.
Lessor's consent to or approval of any act by Lessee requiring Lessor's consent
or approval shall  not be deemed to waive or render unnecessary Lessor's consent
to or approval of any subsequent similar act by Lessee.  The receipt by Lessor
of any Rental with or without knowledge of the breach of any other provision
hereof shall not be deemed a waiver of any such breach.  No partial payment of
Rental (and no acceptance of a partial payment, regardless of any notation on or
accompanying the check) shall be effective to waive the remaining unpaid Rental
or constitute an accord and satisfaction unless Lessor executes a written
agreement explicitly waiving any such unpaid Rental.  No delay or omission in
the exercise of any right or remedy accruing to Lessor upon any breach by Lessee
under this Lease shall impair such right or remedy or be construed as a waiver
of any such breach theretofore or thereafter occurring.

     13.3  Deleted.

           13.6.1  Limitation on Tenant Remedies. Lessee acknowledges and agrees
that in the event of a Lessor default, Lessee's sole and exclusive remedies
shall be as follows:

              (i) To seek monetary damages, provided that under no circumstances
    shall Lessor be liable for loss of business profits or consequential
    damages.

<PAGE>

              (ii) To seek specific performance of Lessor's obligation under
    this Lease to provide public utilities to the Premises and to provide access
    to the Building and Premises.

             (iii) To seek prohibiting injunctive relief solely against
    Lessor's continuance of an existing default.

              (iv) If Lessor fails to repair or maintain the Premises [including
    any portion of the Building-Premises interface (e.g. leaking exterior
    Premises windows and interior Common Areas necessary for access to the
    Premises, but excluding any other portion of the building (e.g. the roof) or
    Common Areas] as required by this Lease, the failure of which materially
    interferes with the conduct of Lessee's normal business activities
    ("Maintenance Item"), Lessee may repair such Maintenance Items; provided
    however, that:  (A) Lessee shall have notified Lessor of the repairs and
    Lessor shall have refused or neglected to commence such repairs; (B) after
    such default by Lessor and subsection (A) notice, Lessee shall have provided
    a second notice that Lessee intends to perform such repairs; (C) such
    repairs shall be performed by qualified, licensed persons and Lessee shall
    ensure satisfactory, lien free completion of such repairs; and (D) and
    Lessee indemnifies, defends, protects and holds harmless Lessor and other
    Industrial Center tenants from and against any damage, injury, loss or claim
    arising in connection with the performance of such repairs.  If Lessor is
    determined to have been in default for the failure to make such repairs,
    Lessor shall reimburse Lessee for the reasonable cost thereof plus interest
    thereon at the Interest Rate.

              (v) Upon entry of a final, non-appealable monetary judgment or
    arbitration award, in addition to any right Lessee may have to enforce such
    judgment or award, Lessee shall be entitled to set off such judgment or
    award against rent thereafter coming due; provided that such right of offset
    shall not be applicable against any Lender holding a security interest in
    such Rents, and receiver, or any transferee of Lessor's interest resulting
    from a judicial or non-judicial foreclosure or deed in lieu thereof.

     Without limitation, Lessee expressly waives all remedies except those
specifically set forth in the Lease and as limited above, including without
limitation:  specific performance, injunction, any right to terminate the Lease
for any reason whatsoever (including without limitation California Civil Code
(S)(S)1932(2), 1933(4) and 1941 or any other current or future law), statutory,
legal or equitable self help remedy (including without limitation California
Civil Code (S)1942 or any other current or future law), and Lessee waives any
right of offset, demand or deduction against Rental pursuant to California Code
of Civil Procedure ("CCP") (S)431.70 or otherwise.

conditions set forth herein, except that the Base Rent shall be increased to
200% of the Base Rent in effect at the end of the Term.

     31.1  Bankruptcy Fees.  If Lessee files for protection under, or
voluntarily or involuntarily becomes subject to, any chapter of the United
States Bankruptcy Code or similar state insolvency laws, the other party shall
be entitled to any and all Fees incurred to protect such party's interest and
other rights under this Lease, whether or not such action results in a
discharge.

49.  Arbitration.  Any controversy or claim arising out of or relating to this
Agreement or the breach thereof shall be settled by arbitration before
J.A.M.S/ENDISPUTE or the successor thereof.  If such organization or its
successor does not exist when such controversy or claim arises, such controversy
or claim shall be settled by arbitration before the American Arbitration
Association.  The site of such arbitration shall be the office of the
appropriate arbitration authority nearest Lessor's principal office, unless
otherwise agreed.  The parties agree that neither of them shall be awarded any
punitive or exemplary damages against the other.  The provisions of this (S)49
shall not apply to any action for unlawful detainer or any action seeking
injunctive relief.

of, the express provisions of the Plan:

          (i)   To determine from time to time which of the persons eligible
     under the Plan shall be granted Options; when and how Options shall be

under such Option shall revert to and again become available for issuance under
the Plan.

5.   Eligibility.
     -----------

     (a) Incentive Stock Options may be granted only to Employees.  Nonstatutory
Stock Options may be granted only to Employees, Directors or Consultants.

     (b) A Director shall be eligible for the benefits of the Plan provided that
such Director's participation conforms to the requirements of Rule 16b-3, if
applicable.

     (c) No person shall be eligible for the grant of an Incentive Stock Option
if, at the time of grant, such person owns (or is deemed to own pursuant to
Section 424(d) of the Code) stock possessing more than ten percent (10%) of the
total combined voting power of all classes of stock of the Company or of any of
its Affiliates unless the exercise price of such Incentive Stock Option is at
least one hundred ten percent (110%) of the Fair Market Value of such stock at
the date of grant.

6.   Option Provisions.
     -----------------

     Each Option shall be in such form and shall contain such terms and
conditions as the Board shall deem appropriate.  The provisions of separate
Options need not be identical, but each Option shall include (through
incorporation of provisions hereof by reference in the Option or otherwise) the
substance of each of the following provisions:

     (a)  Term.  No Option shall be exercisable after the expiration of ten (10)
          ----
years from the date it was granted.

     (b)  Price.  The exercise price of each Incentive Stock Option shall be not
          -----
less than one hundred percent (100%) of the Fair Market Value of the stock
subject to the Option on the date the Option is granted.  Notwithstanding the
foregoing, the exercise price of any Incentive Stock Option granted hereunder to
any stockholder possessing at least 10% of the total combined voting power of
all classes of stock of the Company shall be not less than one hundred ten
percent (110%) of the Fair Market Value of the stock subject to the Option on
the date the Option is granted.
<PAGE>

     (c)  Consideration.  The purchase price of stock acquired pursuant to an
          -------------
Option shall be paid, to the extent permitted by applicable statutes and
regulations, either (i) in cash at the time the Option is exercised, (ii) at the
discretion of the Board or the Committee, either at the time of the grant or
exercise of the Option, by delivering to the Company other shares of Common
Stock of the Company (provided that the shares have been held for the period
required to avoid a charge to the Company's reported earnings), (iii) at the
discretion of the Board or the Committee, either at the time of the grant or
exercise of the Option, by delivering to the Company all or any part of an
Option granted under this Plan for a cashless exercise (provided that such
cashless exchange will not result in a charge to the Company's reported
earnings), or (iv) by tendering any other form of legal consideration that may
be acceptable to the Board.

     (d)  Transferability.  An Incentive Stock Option shall not be transferable
          ---------------
except by will or by the laws of descent and distribution, and shall be
exercisable during the lifetime of the person to whom the Incentive Stock Option
is granted only by such person.  A Nonstatutory Stock Option granted to an
Optionee subject to Section 16 of the Exchange Act on the date of grant shall
not be transferable except by will or by the laws of descent and distribution or
pursuant to a qualified domestic relations order satisfying the requirements of
Rule 16b-3 and the rules thereunder (a "QDRO"), and shall be exercisable during
the lifetime of the person to whom the Option is granted only by such person or
any transferee pursuant to a QDRO.  A Nonstatutory Stock Option granted to an
Optionee who is not subject to Section 16 of the Exchange Act on the date of
grant may not be transferable except by will or by the laws of descent and
distribution, unless otherwise permitted by the Board.  The person to whom the
Option is granted may, by delivering written notice to the Company, in a form
satisfactory to the Company, designate a third party who, in the event of the
death of the Optionee, shall thereafter be entitled to exercise the Option.

     (e)  Vesting.  The total number of shares of stock subject to an Option
          -------
may, but need not, be allotted in periodic installments (which may, but need
not, be equal). The Option Agreement may provide that from time to time during
each of such installment periods, the Option may become exercisable ("vest")
with respect to some or all of the shares allotted to that period, and may be
exercised with respect to some or all of the shares allotted to such period
and/or any prior period as to which the Option became vested but was not fully
exercised. The Option may be subject to such other terms and conditions on the
time or times when it may be exercised (which may be based on performance or
other criteria) as the Board may deem appropriate. The provisions of this
Section 6(e) are subject to any Option provisions governing the minimum number
------------
of shares as to which an Option may be exercised.

     (f)  Termination of Employment or Relationship as a Director or Consultant.
          ---------------------------------------------------------------------
In the event an Optionee's Continuous Status as an Employee, Director or
Consultant terminates (other than upon the Optionee's death or disability), the
Optionee may exercise his or her Option (to the extent that the Optionee was
entitled to exercise it at the date of termination) but only within such period
of time ending on the earlier of (i) the date ninety (90) days after the
termination of the Optionee's Continuous Status as an Employee, Director or
Consultant (or such longer period specified in the Option Agreement), or (ii)
the expiration of the term of the Option as set forth in the Option Agreement.
If, after termination, the Optionee does not exercise his or her Option within
the time specified in the Option Agreement, the Option shall terminate, and the
shares covered by such Option shall revert to and again become available for
issuance under the Plan.

     (g)  Disability of Optionee.  In the event an Optionee's Continuous Status
          ----------------------
as an Employee, Director or Consultant terminates as a result of the Optionee's
disability, the Optionee may exercise his or her Option (to the extent that the
Optionee was entitled to exercise it at the date of termination), but only
within such period of time ending on the earlier of (i) the date six (6) months
following such termination (or such longer period specified in the Option
Agreement), or (ii) the expiration of the term of the Option
<PAGE>

as set forth in the Option Agreement. If, at the date of termination, the
Optionee is not entitled to exercise his or her entire Option, the shares
covered by the unexercisable portion of the Option shall revert to and again
become available for issuance under the Plan. If, after termination, the
Optionee does not exercise his or her Option within the time specified herein,
the Option shall terminate, and the shares covered by such Option shall revert
to and again become available for issuance under the Plan.

     (h) Death of Optionee.  In the event of the death of an Optionee during, or
         -----------------
within a period specified in the Option after the termination of, the Optionee's
Continuous Status as an Employee, Director or Consultant, the Option may be
exercised (to the extent the Optionee was entitled to exercise the Option at the
date of death) by the Optionee's estate, by a person who acquired the right to
exercise the Option by bequest or inheritance or by a person designated to
exercise the option upon the Optionee's death pursuant to Section 6(d), but only
                                                          ------------
within the period ending on the earlier of (i) the date twelve (12) months
following the date of death (or such longer period specified in the Option
Agreement), or (ii) the expiration of the term of such Option as set forth in
the Option Agreement.  If, at the time of death, the Optionee was not entitled
to exercise his or her entire Option, the shares covered by the unexercisable
portion of the Option shall revert to and again become available for issuance
under the Plan.  If, after death, the Option is not exercised within the time
specified herein, the Option shall terminate, and the shares covered by such
Option shall revert to and again become available for issuance under the Plan.

7.   Cancellation and Regrant of Options.
     -----------------------------------

     The Board or the Committee shall have the authority to effect, at any time
and from time to time, (i) the repricing of any outstanding Options under the
Plan, and/or (ii) with the consent of the affected holders of Options, the
cancellation of any outstanding Options under the Plan and the grant in
substitution therefor of new Options under the Plan covering the same or
different numbers of shares of stock, but having an exercise price per share not
less than one hundred percent (100%) of the Fair Market Value in the case of an
Incentive Stock Option or, in the case of a ten percent (10%) stockholder (as
described in Section 5(c)) not less than one hundred ten percent (110%) of the
             ------------
Fair Market Value in the case of an Incentive Stock Option.

8.   Covenants of the Company.
     ------------------------

     (a) During the terms of the Options, the Company shall keep available at
all times the number of shares of stock which would be issuable under such
outstanding Options.

     (b) The Company shall seek to obtain from each regulatory commission or
agency having jurisdiction over the Plan such authority as may be required to
issue and sell shares of stock upon exercise of the Options; provided, however,
that this undertaking shall not require the Company to register under the
Securities Act either the Plan, any Options or any stock issued or issuable
pursuant to any such Options.  If, after reasonable efforts, the Company is
unable to obtain from any such regulatory commission or agency the authority
which counsel for the Company deems necessary for the lawful issuance and sale
of stock under the Plan, the Company shall be relieved from any liability for
failure to issue and sell stock upon exercise of such Options unless and until
such authority is obtained.

9.   Use of Proceeds from Stock.
     --------------------------

     Proceeds from the sale of Common Stock upon exercise of the Options shall
constitute general funds of the Company.
<PAGE>

10.  Miscellaneous.
     -------------

     (a) Neither an Optionee nor any person to whom an Option is transferred
under Section 6(d) shall be deemed to be the holder of, or to have any of the
      ------------
rights of a holder with respect to, any shares subject to such Option unless and
until such person has satisfied all requirements for exercise of the Option
pursuant to its terms.

     (b) Nothing in the Plan or any Option granted pursuant thereto shall confer
upon any Employee, Director, Consultant or other holder of Options any right to
continue in the employ of the Company or any Affiliate (or to continue acting as
a Director or Consultant) or shall affect the right of the Company or any
Affiliate to terminate the employment or relationship as a Director or
Consultant of any Employee, Director, Consultant or other holder of Options with
or without cause.

     (c) To the extent that the aggregate Fair Market Value (determined at the
time of grant) of stock with respect to which Incentive Stock Options are
granted are exercisable for the first time by an Optionee during any calendar
year under all plans of the Company and its Affiliates exceeds One Hundred
Thousand Dollars ($100,000), the Options or portions thereof which exceed such
limit (according to the order in which they were granted) shall be treated as
Nonstatutory Stock Options.

     (d) The Company may require any person to whom an Option is granted, or any
person to whom an Option is transferred under Section 6(d), as a condition of
                                              ------------
exercising any Option, (1) to give written assurances satisfactory to the
Company as to such person's knowledge and experience in financial and business
matters and/or to employ a purchaser representative reasonably satisfactory to
the Company who is knowledgeable and experienced in financial and business
matters, and that he or she is capable of evaluating, alone or together with the
purchaser representative, the merits and risks of exercising the Option; and (2)
to give written assurances satisfactory to the Company stating that such person
is acquiring the stock subject to the Option for such person's own account and
not with any present intention of selling or otherwise distributing the stock.
The foregoing requirements, and any assurances given pursuant to such
requirements, shall be inoperative if (i) the issuance of the shares upon the
exercise or acquisition of stock under the Option has been registered under a
then currently effective registration statement under the Securities Act, or
(ii) as to any particular requirement, a determination is made by counsel for
the Company that such requirement need not be met in the circumstances under the
then applicable securities laws.  The Company may, upon advice of counsel to the
Company, place legends on stock certificates issued under the Plan as such
counsel deems necessary or appropriate in order to comply with applicable
securities laws, including, but not limited to, legends restricting the transfer
of the stock.

     (e) To the extent provided by the terms of an Option Agreement, the person
to whom an Option is granted may, at the discretion of the Board, satisfy any
mandatory federal, state or local tax withholding obligation relating to the
exercise or acquisition of stock under an Option by any of the following means
or by a combination of such means:  (1) tendering cash payment; (2) authorizing
the Company to withhold shares from the shares of the Common Stock otherwise
issuable to the Participant as a result of the exercise or acquisition of stock
under the Option provided that such arrangement will not result in a charge to
the Company's reported earnings; or (3) delivering to the Company owned and
unencumbered shares of the Common Stock of the Company that have been held for
the period required to avoid a charge to the Company's reported earnings.  The
exercise of the Option may be conditioned upon the receipt by the Company of
satisfactory evidence of the Participant's satisfaction of any withholding
obligations.
<PAGE>

11.  Adjustments Upon Changes in Stock.
     ---------------------------------

     (a) Subject to any required action by stockholders, the number of shares
which may be purchased upon the exercise of each outstanding Option shall be
proportionately increased or decreased upon the occurrence of any change,
increase or decrease in the number and type of issued shares of Common Stock of
the Company, without receipt of consideration by the Company, which change
results from a stock split, a stock dividend, a merger, consolidation,
reorganization, reincorporation, a recapitalization, a combination of shares,
change in corporate structure or other like capital adjustment, so that upon the
exercise of each Option the holders of such Options shall receive the number and
type of securities which the holders would have received had the Options been
exercised on the date preceding such change, increase or decrease.  In the event
of any such adjustment, the exercise price for each share shall be likewise
adjusted in inverse proportion to the increase or decrease in the number of
shares purchasable.

     (b) In the event of:  (1) a dissolution, liquidation or sale of
substantially all of the assets of the Company; (2) a merger or consolidation in
which the Company is not the surviving corporation; or (3) a reverse merger in
which the Company is the surviving corporation but the shares of the Company's
Common Stock outstanding immediately preceding the merger are converted by
virtue of the merger into other property, whether in the form of securities,
cash or otherwise, then to the extent permitted by applicable law:  (i) any
surviving corporation shall assume any Options outstanding under the Plan or
shall substitute similar Options for those outstanding under the Plan, or (ii)
such Options shall continue in full force and effect.  In the event any
surviving corporation refuses to assume or continue such Options, or to
substitute similar options for those outstanding under the Plan, then, with
respect to Options held by persons then performing services as Employees,
Directors or Consultants, the time during which such Options vest shall be
accelerated and the Options terminated if not exercised prior to such event.

12.  Amendment of the Plan.
     ---------------------

     (a) The Board at any time, and from time to time, may amend the Plan
provided that the implementation of such amendment by the Company complies with
all applicable law.

     (b) The Board may in its sole discretion submit any other amendment to the
Plan for stockholder approval, including, but not limited to, amendments to the
Plan intended to satisfy the requirements of Section 162(m) of the Code and the
regulations promulgated thereunder regarding the exclusion of performance-based
compensation from the limit on corporate deductibility of compensation paid to
certain executive officers.

     (c) It is expressly contemplated that the Board may amend the Plan in any
respect the Board deems necessary or advisable to provide eligible Employees,
Directors or Consultants with the maximum benefits provided or to be provided
under the provisions of the Code and the regulations promulgated thereunder
relating to Incentive Stock Options and/or to bring the Plan and/or Incentive
Stock Options granted under it into compliance therewith.

     (d) Rights and obligations under any Option granted before amendment of the
Plan shall not be altered or impaired by any amendment of the Plan unless (i)
the Company requests the consent of the person to whom the Option was granted,
and (ii) such person consents in writing.

13.  Termination or Suspension of the Plan.
     -------------------------------------

     (a) The Board may suspend or terminate the Plan at any time.  Unless sooner
terminated, the Plan shall terminate on October 1, 2007, which shall be within
ten (10) years from the date the Plan is
<PAGE>

adopted by the Board or approved by the stockholders of the Company, whichever
is earlier. No Options may be granted under the Plan while the Plan is suspended
or after it is terminated.

     (b) Rights and obligations under any Option granted while the Plan is in
effect shall not be altered or impaired by suspension or termination of the
Plan, except with the consent to the person to whom the Option was granted.

14.  Effective Date of Plan.
     ----------------------

     The Plan shall become effective as determined by the Board, but no Options
granted under the Plan shall be exercised unless and until the Plan has been
approved by the stockholders of the Company, which approval shall be within
twelve (12) months before or after the date the Plan is adopted by the Board.

15.  Financial Information.
     ---------------------

     The Company will provide to each Optionee financial statements of the
Company at least annually in accordance with Section 260.140.46 of Title 10 of
the California Code of Regulations.
