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.

          See Addendum, Paragraph 54.

          2.2  Compliance: All applicable laws, covenants or restrictions of
record, building codes, regulations and ordinances are described herein as
("Applicable Requirements.").

this Lease are as specified in the Addendum Paragraph 51.

          4.   Rent.

designate in writing. Acceptance of a payment which is less than the amount then

<PAGE>

          6.   Use.

          6.1  Use: Lessee shall use and occupy the Premises only for the Agreed
Use, 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 damages to neighboring
properties.

          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 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 therefore. 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 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 Premise, 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 by any governmental body with


                                       3

<PAGE>

jurisdiction thereof, whether or not formally ordered or required, for the clean
up 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.

          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 become 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 which are in Lessee's
possession or control, and other information evidencing Lessee's compliance with
any Applicable Requirements reasonably 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, warning,
complaint or report pertaining to or involving the failure of 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 (provided, that Lessor shall
use commercially reasonable efforts to give whatever notice is practical in the
circumstances), and otherwise on 48 hours notice 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
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. See Addendum, Paragraph 55.

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

          7.1  Lessee's Obligations.

          (a)  In General. Subject to the provisions of Paragraph 6.3 (Lessee's
Compliance with Applicable Requirements), 7.2 (Lessor's Obligations), 9 (Damage
or Destruction), and 14 (Condemnation), Lessee shall, at Lessee's sole expense,
keep the Premises, Utility Installations, and Alterations in good order,
condition and repair (whether or not the portion of the Premises requiring
repairs, or the means of repairing the same, are reasonably or readily
accessible to Lessee, and whether or not the need for such repairs occurs as a
result of Lessee's use, any prior use, the elements or the age of such portion
of the Premises), including, but not limited to, all equipment or facilities,
such as plumbing, heating, ventilating, air-conditioning, electrical, lighting
facilities, boilers, pressure vessels, fire protection system, fixtures, walls
(interior and exterior), foundations, ceilings, roofs, floors, windows, doors,
plate glass, skylights, landscaping, driveways, parking lots, fences, retaining
walls, signs, sidewalks

                                        4

<PAGE>

and parkways located in, on, or adjacent to the Premises. Lessee, in keeping the
Premises in good order, condition and repair, shall exercise and perform good
maintenance practices, specifically including the procurement and maintenance of
the service contracts required by Paragraph 7.1(b) below. Lessee's obligations
shall include restorations, replacements or renewals when necessary to keep the
Premises and all improvements thereon or a part thereof in good order, condition
and state of repair. Lessee shall, during the term of this Lease, keep the
exterior appearance of the Building in a first-class condition consistent with
the exterior appearance of other similar facilities of comparable usage and size
in the vicinity, including, when necessary the exterior repainting of the
Building.

          (b)  Service Contracts. Lessee shall, at Lessee's sole expense,
procure and maintain contracts, with copies to Lessor, in customary form and
substance for, and with contractors specializing and experienced in the
maintenance of the following equipment and improvements, if any, if and when
installed on the Premises: (1) HVAC equipment, (ii) boiler, and pressure
vessels, (iii) fire extinguishing systems, including fire alarm and/or smoke
detection, (iv) landscaping and irrigation systems, (v) roof covering and
drains, (vi) driveways and parking lots, (vii) clarifiers (viii) basic utility
feed to the perimeter of the Building, and (ix) any other equipment, if
reasonably required by Lessor. Notwithstanding the foregoing, Lessee shall have
the right to perform the maintenance required hereunder with its own personnel
so long as the maintenance standards required hereunder are observed. In any
event, Lessee shall furnish Lessor, no less frequently than quarterly,
reasonable evidence that the required maintenance is taking place.

          7.2  Lessor's Obligations. Subject to the provisions of Paragraph 9
(Damage or Destruction) and 14 (Condemnation), it is intended by the Parties
hereto that Lessor have no obligation, of in any manner whatsoever, to repair
and maintain the Premises, or the equipment therein, all 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 the 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 fending 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. However,
Lessee may make Alterations and Utility Installations to the Premises, without
Lessor's prior consent, so long as no one of such Alterations or Utility
Installations exceeds $500,000 in cost. Lessee shall, however, keep Lessor
reasonably informed of the improvements it is making to the Premises, so

                                        5

<PAGE>

that Lessor may file notices of nonresponsibility in a timely manner. Lessee may
not make any Alterations which reduce the square footage of the improvements on
the Premises.

          (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 plan and specifications.
For work which requires Lessor's consent, 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 mechanic's or
materialmen's lien against 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
the Lease, become the property of Lessor and be surrendered by Lessee with the
Premises.

          (b)  Removal. By delivery to Lessee of written notice from Lessor not
earlier than ninety (90) and not later than thirty (30) days prior to the end of
the term of this Lease, Lessor may require any or all Lessee Owned Alterations
or Utility Instructions which are constructed after the Commencement Date be
removed by the expiration or termination of this Lease. Lessor may require the
removal at any time of all or any part of any Lessee Owned Alterations or
Utility Installations made without the required consent, which are constructed
after the Commencement Date (or if this Lease is terminated before the end of
such term, then at any time within thirty (30) days after the end of such term).

                                        6

<PAGE>

          (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 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, furnishing, 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.

          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 performances 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 may 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,

                                        7

<PAGE>

and to any Lender(s) insuring loss or damage to the Premises. The amount of such
insurance shall be equal to the full replacement cost of the Premises, as the
same shall exist from time to time, but in no event more than the commercially
reasonable and available insurable value thereof. 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 earthquake,
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 ($50,000) per occurrence, and Lessee shall be liable for such deductible
amount in the event of an insured Loss.

          (b)  (Rental Value.)

          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 $50,000 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 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 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." 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. If Lessor does not
receive such evidence in a timely fashion after five business days notice given
to the Lessee of the need for

                                        8

<PAGE>

such insurance, then Lessor may order such insurance and change 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 fall 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 the gross negligence or willful misconduct
of Lessor, its agents, master or ground lessors, partners, and lenders, 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 shall upon notice 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 defended or 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's employees, contractors, invitees, customers, or any other
person in or about the Premises, 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 existing on or 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.

          8.9  Earthquake and Flood Insurance. Lessee shall not be required to
obtain earthquake or flood insurance, and Lessor shall not be entitled to pass
through to Lessee the cost of any earthquake or flood insurance which Lessor
obtains.

          9.1  Definitions.

                                        9

<PAGE>

          (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 twelve (12) months or less
from the date of the damage or destruction. Lessor shall notify Lessee in
writing within 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 twelve (12) months or
less from the date of the damage or destruction. Lessor shall notify Lessee in
writing within 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 the cost to repair or rebuild the
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 or which Lessor reasonably
determines will not cost in excess of $3,000,000 to repair.

          (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 Lessee shall, at Lessee's expense, repair such
damage (including Lessee's Trade Fixtures and Lessee Owned Alterations and
Utility Installations) as soon as reasonably possible and this Lease shall
continue in full force and effect; and Lessor shall make any applicable
insurance proceeds available to Lessee on a reasonable basis for that purpose
subject to customary controls typical in construction lending, including
requirement that the job funds be kept in balance. 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 _____ _______ in proceeds (including the deductible which is Lessee's
responsibility) as and when required to complete said repairs.

          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
sixty (60) 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 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 or Lessee's commitment to pay for the repair

                                       10

<PAGE>

of such damage without 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. If
Lessee gives such notice, 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 and shall be entitled to a reasonable fee
for its efforts. 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. If a Premises Total Destruction occurs, this
Lease shall terminate sixty (60) days following such Destruction, Lessor shall
be entitled to obtain and retain all insurance proceeds payable on account of
such total destruction; provided, that so long as the amount which Lessor is
able to recover from the insurance carriers is not thereby reduced. Lessee shall
have the right to obtain and retain insurance proceeds payable on account of
damage to its Trade Fixtures and personal property. 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. Notwithstanding the foregoing, if Lessee so notifies Lessor
within thirty (30) days after a Premises Total Destruction occurs, Lessee shall
have the right to repair and restore all damage without reimbursement from
Lessor. In such case, Lessee shall provide Lessor with the necessary funds or
satisfactory assurances thereof within thirty (30) days after making such
commitment. If Lessee gives such notice, this Lease shall continue in full force
and effect and Lessee 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 of Premises Total
Destruction.

          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 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 the time has an exercisable option to extend the 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. In the event of such termination, Lessor shall be
entitled to obtain and retain all insurance proceeds payable on account of such
Total Destruction; provided, that so long as the amount which Lessor is able to
recover from the insurance carriers is not thereby reduced, Lessee shall have
the right to obtain and retain insurance proceeds on account of damage to its
Trade Fixtures and personal property.

                9.6      Abatement of Rent; Lessee's Remedies.

                (a)      Abatement. In the event of Premises Total Destruction
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 hereunder shall be performed by
Lessee, and Lessor shall have no liability for any such damage, destruction,
remediation, repair or restoration except as provided herein.

                9.7      Termination - Advance Payments. Upon termination of
this Lease pursuant to Paragraph 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.

                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 fees imposed upon or levied against any legal or equitable
interest of Lessor in the Premises, Lessor's right to other income therefrom,
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 reasons of
events occurring during the term of this Lease, including but not limited to, a
change in the ownership of the Premises. See Addendum, Paragraph 56.

                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 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
therefore upon demand. See Addendum, Paragraph 56.

                                       12

<PAGE>

                (b)      Advance Payment. In the event Lessee incurs a late
charge on any Rent payment two or more times in any twelve month period, 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 monies paid to Lessor under this
Paragraph may be intermingled with other monies of Lessor and shall not bear
interest.

                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 of 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 such property
to be assessed and billed separately from the real property of Lessor. If any of
the 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, "assign or assignment") or
sublet all or any part of Lessee's interest in this Lease or in the Premises
without Lessor's prior written consent. In accordance with Paragraph 36, Lessor
agrees that it consent will not be unreasonably withheld.

                (b)      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 assignment or subletting as a noncurable
Breach, Lessor may either: (i) terminate this Lease, or (ii) upon thirty

                                       13

<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, the purchase price of any option to purchase the
Premises held by Lessee shall be subject to such adjustment to one hundred ten
percent (110%) or the price previously 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 such adjustment to one hundred
ten percent (110%) or a 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.

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

                (d)      Notwithstanding the foregoing, Lessee shall have the
right, upon prior notice to Lessor, to assign its interest in this Lease or
sublet all or part of the Premises to a transferee (i) whose net worth,
financial condition and ability to pay are sufficient to enable such transferee
to perform all of the obligations of Lessee hereunder (or in the case of a
subletting, all of Lessee's obligations pertaining to that portion of the
Premises which is sublet) and (ii) who uses the Premises for the purposes
permitted in this Lease. Such transfer will not affect the obligations of Lessee
hereunder. See Addendum, Paragraphs 64 and 65.

                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 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 anyone 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

                                       14

<PAGE>

with a fee of $1,000 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 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 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 said Rent. Lessor shall not, by reason of the
foregoing or any assignment of such sublease, nor by reason of the collection of
Rent, be 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 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.

                (d)      No sublessee shall further assign or sublet all or any
part of the Premises without Lessor's prior written consent. See Addendum,
Paragraph 64. 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:

                                       15

<PAGE>

                (a)      The abandonment of the Premises; or the vacating of the
Premises without providing a commercially reasonable level of security, or where
the coverage of the property insurance described 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
Estoppel Certificate, (v) a required subordination, (vi) any document requested
under Paragraph 42 (easements), or (vii) 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. (S). 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 13.1(e) is contrary to any applicable law, such
provision shall be of no force or effect, and not affect the validity of the
remaining provision.

                (f)      The discovery that any audited financial statement of
Lessee given to Lessor was materially false, or that any unaudited financial
statement of Lessee given to Lessor was materially false except for
unintentional or clerical errors.

                (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;

                                       16

<PAGE>

                13.2    Remedies. If Lessee fails to perform any of its
affirmative duties or obligations, within ten (10) days after written notice (or
in the case of an emergency, without notice (provided, that Lessor shall use
commercially reasonable efforts to give whatever notice is practical in the
circumstances)), 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 therefore. 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 of rent to be made by
Lessee during the next twelve (12) months 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 the award of the amount
by which the unpaid rent which would have been earned after termination until
the time of award exceeds the amount of such rental loss that 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 the
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 Breach of this
Lease entitling Lessor to the remedies provided for in this Lease and/or by said
statute. See Addendum, Paragraph 57.

                (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

                                       17

<PAGE>

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 term
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 and
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 so
stated in writing by Lessor at the time of such acceptance. Notwithstanding the
foregoing, no Inducement Provision shall be deemed deleted unless (i) the Lessee
does not cure its Default within the time period granted herein and (ii) such
Default is not cured within a further thirty (30) days after Lessor notifies
Lessee of its failure to effect such cure within such cure period.

                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 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 from the date
when due, as to scheduled payments, or the thirty-first (31/st/) 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

                                       18

<PAGE>

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 address 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. See Addendum, Paragraph 58.

                (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. See
Addendum, Paragraph 58.

                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
thirty (30) 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) terminates 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 considered the property of the Lessee and Lessee
shall be entitled to any and all compensation which is payable therefore. 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. See
Addendum, Paragraph 59.

                15.     Brokers' Fee.

                15.1    Representation 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 cost, expenses,
and/or attorney's 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 and in the case of Lessor, its lender or prospective lender and any
prospective purchaser of the Premises.

                (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 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, (iii)
if Lessor is the Requesting Party, not more than one month's Rent has been paid
in advance and (iv) to such other effect as the Responding Party could have been
requested to respond pursuant to paragraph (a) above. Prospective purchasers and
encumbrances 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.

                                       20

     17. Definition of Lessor. The term "Lessor" as used herein shall mean to
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 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 delivery of the Security Deposit, as aforesaid,
the prior Lessor shall be relieved of all liability with respect to the
obligations and/or covenants under this Lease thereafter to be performed by the
Lessor. Subject to the foregoing, 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 Substance 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
obligation or 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 contemporaneous agreement or understanding shall be
effective.

     23. Notices.

     23.1 Notice Requirements. All notices required or permitted by the Lease
shall be in writing and may be delivered in person (by hand 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

                                       21

<PAGE>

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.

        23.3  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,
covenant or condition hereof, or of any subsequent Default or Beach 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 by
Lessee may be accepted by Lessor on account of monies or damage due Lessor,
notwithstanding any qualifying statements or conditions made by Lessee in
connection therewith, which such statements and/or conditions 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.

        23.4  Recording. Either Lessor or 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 requiring recordation shall be
responsible for payment of all fees applicable thereto.

        23.5  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, 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.

        23.6  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.

        23.7  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 context, the singular shall include

                                       22

<PAGE>

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.

        23.8  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 Loan shall be initiated in
the county in which the Premises are located.

        24.   Subordination; Attornment;. Non-Disturbance.

        24.1  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 to 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 (except that Lessor's
Lender shall have the obligation to perform the obligations of Lessor under this
Lease during any period of time after it forecloses or takes a deed in lieu and
for so long thereafter as it owns fee title to the Premises). Any Lender may
elect to have this Lease and/or any Options 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.

        24.2  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
occurring prior to acquisition of ownership (ii) be subject to any offsets or
defenses which Lessee might have against any lessor, or (iii) be bound by
prepayment of more than one (1) month's rent.

        24.3  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,
Lessee 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 its Premises. In the event that Lessor is unable to provide the
Non-Disturbance Agreement within said sixty (60) days then Lessee may, at
Lessees's option, directly contact Lessor leader and attempt to negotiate for
the execution and delivery of a Non-Disturbance Agreement.

        24.4  Self-Executing.  The agreements contained in this Paragraph 30
shall be effective without the execution of any further documents; provided,
however, that, upon written

                                       23

<PAGE>

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 subordination,
attornment and/or Non-Disturbance Agreement provided for herein.

        25.   Attorney's Fees. If any Party or Broker brings an action or
proceeding involving the Premises to enforce the terms hereof or to declare
rights hereunder, the Prevailing Party (as hereafter defined) in any such
proceeding, action, or appeal thereon or their post judgment proceeding, shall
be entitled to reasonable attorneys' fees. Such fees may be awarded in the same
suit or recovered in a separate suit, whether or not such action or proceeding
is pursed to decision or judgment. The term, "Prevailing Party" shall include,
without limitation, a Party 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 of its claim or defense. The attorneys' fees
award shall not be computed in accordance with any court fee schedule, but shall
be such as to fully reimburse all attorneys' fees reasonably incurred. In
addition, Lessor shall be entitled to attorneys' 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.

        26.   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
the emergency (but Lessor shall give such notice as is practical in the
circumstances) and otherwise on 48 hours notice 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 Lease" signs. Lessee may at any
time place on or about the Premises any ordinary "For Sublease" sign. (See
Addendum, Paragraph 55.)

        27.   Auction. 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
wither to permit an auction.

        28.   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.

        29.   Termination; Merger. Unless specifically stated otherwise in
writing by Lessor, the voluntary or other surrender of this Lease by Lessee, the
actual termination or cancellation hereof, or a termination hereof by Lessor for
Breach by Lessee, shall automatically terminate any sublease or lesser estate of
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.

                                       24

<PAGE>

        30. Consents. Except as otherwise provided herein, wherever in this
Lease the consent of a Party required to an act by or for the other Party, such
consent shall not be unreasonably withheld or denied. 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 therefore. Lessor's consent to any act, assignment or
subletting shall not constitute an acknowledgement 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 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 Lessors
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 the 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. See Addendum, paragraph 57)

        31.   Guarantor.

        31.1  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.

        31.2  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
Guarantors behalf to obligate Guarantor, and in the case of a 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.

        32.   Quiet Possession. Subject to payment by Lessee of the Rent and
performance of all the convents, 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 Promises during the term hereof, subject to all
matters of record.

        33.   Options. See Addendum, Paragraph 51.

        33.1  Definition. ("Option") 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.

                                       25

<PAGE>

     33.2 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 Lessor 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.

     33.3 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.

     33.4 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 reasons of Lessee's inability to exercise an Option
because of the provisions of Paragraph 33.4(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.

     34. 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.

     35. 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.

                                       26

<PAGE>

     36. 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 and acknowledge any documents reasonably requested
by Lessor to effectuate any such easement rights, dedications, maps or

     51. Term and Options to Extend.

         51.1 1205 Coleman. The term of this Lease as it pertains to 1205
              ------------
Coleman begins on March 1, 2000 (the "Commencement Date") and ends October 30,
2011.

         (a) Lessee shall have the option to extend the term of this Lease as

               (c) If Lessee duly exercises its option to extend contained in

                                       30

<PAGE>

         51.4 Term. As used herein, "Term" includes any extensions of the term
              ----
of this Lease which are duly exercised by Lessee.

         51.5 Miscellaneous. It is not necessary to exercise an available
              -------------
extension option for 1205 Coleman or for 1450 Coleman in order to be able to
exercise an available extension option for the other. If this Lease expires as
to 1250 Coleman or 1450 Coleman but not the other, then (i) such expiration
shall not affect the provisions of this Lease as they pertain to the other
parcel, which provisions shall continue in full force and effect, subject to all
of the other terms and provisions of this Lease, and (ii) the Premises will be
deemed to consist only of the parcel (1205 Coleman or 1450 Coleman, as the case
may be) which continues to be subject to the terms of this Lease.

     52. Base Rent.

         52.1 Base Rent through September 30, 2001. The Base Rent for the
              ------------------------------------
Premises shall be payable beginning March 1, 2000 through the expiration or
earlier termination of this Lease. The Base Rent for the period between March 1,
2000 and September 30, 2001 is Two Hundred Sixty-Seven Thousand Forty Dollars
($267,040) per month, payable on the first day of each and every month beginning
on January 1, 2000, in advance.

         52.2 Base Rent from October 1, 2001 through October 30, 2011. The Base
              -------------------------------------------------------
Rent for the Premises for the period between October 1, 2001 and October 30,
2011 is Three Hundred Thirty-Nine Thousand Two Hundred Nine Dollars ($339,209 )
per month, payable in advance on the first day of each and every month beginning
on October 1, 2001, subject to adjustment in accordance with Paragraph 52.3.
However, if Lessee does not exercise its option contained in Paragraph 51.2(a)
to extend the Term with respect to 1450 Coleman to October 30, 2011, then the
Base Rent for the period of November 1, 2006 through October 30, 2011 will be
calculated solely with reference to 1205 Coleman and will be Three Hundred
Thirty-eight Thousand Seventy-Eight Dollars ($338,078) per month, payable in
advance on the first day of each month beginning November 1, 2006, subject to
further adjustment pursuant to Paragraph 52.3.

         52.3 Adjustments to Base Rent.
              ------------------------

         (a) On October 1 of each of the years 2002 through 2010 the Base Rent
for the Premises for the twelve (12) month period beginning on such date will
increase by three percent (3%) over the Base Rent for the prior twelve (12)month
period. For example, the monthly Base Rent for the twelve (12) month period
beginning October 1, 2002 will be $349,385.27 and the monthly Base Rent for the
twelve (12) month period beginning October 1, 2003 will be $359,866.83.

         (b) However, if Lessee does not exercise its option contained in
Paragraph 51.2(a) to extend the Term with respect to 1450 Coleman to October 30,
2011, then the increases to Base Rent called for by paragraph (a) above for the
twelve (12) month periods beginning October 1, 2006 and continuing through
October 30, 2010 shall be calculated as if 1450 Coleman had never been part of
the Premises. By way of example, the Base Rent for the twelve (12) month period
beginning October 1, 2006 would be the Base Rent which would have been payable
for the prior twelve (12) month period with respect to 1205 Coleman alone,
increased by three percent (3%) per annum. The Base Rent which "would have been
payable with respect to 1205 Coleman" is eighty-five and ninety-seven hundredths
percent (85.97%) of the Base Rent which was payable with respect to the Premises
(including both 1205 Coleman and 1450 Coleman) with respect to such period.

     A matrix showing the adjusted Base Rent through October 30, 2011 is
contained on Schedule 1 attached hereto and Incorporated herein by reference.

         52.4 Base Rent During Certain Option Periods.  The Base Rent payable
              ---------------------------------------
with respect to the Premises foreach option period described in Paragraphs 51.1
(a) and (b) and 51.2 (b) and (c) shall be ninety-five percent (95%) of the Fair
Rental Value of the Premises which are covered by this Lease during such option
periods. "Fair Rental Value" for purposes of this Lease means the greater of (1)
the Base Rent for the Premises subject to the option as of the date which is
immediately prior to the first day of the option period and (ii) the prevailing
rental rate for premises in the vicinity of the Premises subject to the option
which are zoned and

                                       31

<PAGE>

improved in a manner similar to the Premises as of one (1) year prior to the
first day of the option period. Regardless of whether clause (i) or (ii) is
chosen, the Base Rent for each option period shall be increased on each
anniversary of the first day of the option period by an amount equal to three
percent (3%) of the Base Rent for the prior year. In the event that Lessor and
Lessee cannot agree in writing on the Fair Rental Value within thirty (30) days
after exercise of any option by Lessee, the Fair Rental Value shall be
determined in accordance with Paragraph 61.

         53. Use. The Agreed Use of the Premises is the uses and purposes for
which the Premises are being used on the date hereof by Lessee, including the
design, development and manufacturing of military vehicles and general research
and development.

         54. Condition of Property. Lessor and Lessee acknowledge that because
Lessee has been a lessee of the Premises for many years and Lessor just acquired
the Premises, Lessee has much greater knowledge of the Premises, including the
improvements thereon, than does Lessor. Accordingly, Lessee further acknowledges
that Lessor is making no representation or warranty whatsoever, express or
implied, with respect to the Premises, any improvements thereon, the condition
thereof or the compliance thereof with Applicable Law. Neither Lessor nor Lessee
has any obligation to the other to disclose any fact or condition with respect
to the Premises which such party discovered or may have discovered in connection
with its investigation or occupancy of the Premises prior to the date hereof.

any other order or environmental requirement to which Lessee and FMC are
subject. Lessee and FMC shall remain responsible for investigation and
remediation of all Existing Contamination to the extent they were responsible

Easement, between FMC and Lessor, dated December 21, 1999 (the "Right of Entry
Agreement"), and is familiar with the terms and conditions applicable to the FMC
Indemnity. Lessee hereby agrees that it shall conduct its operations on the
Premises in accordance with the FMC Indemnity and the Right of Entry Agreement,
and shall ensure that Lessor's rights and obligations under the FMC Indemnity
and the Right of Entry Agreement are not adversely impacted by Lessee's
operations on and/or use of the Premises. Lessor shall use commercially
reasonable efforts to ensure that FMC's activities will be conducted in a manner
which does not unreasonably interfere with the activities of Lessee on the
Premises.

             (b) Investigation and Remediation of Hazardous Substances. Upon

resulting contamination itself, as set forth in Paragraph 6.2(c) of the Lease.
                                                ----------------
Lessee must notify Lessor in writing of its intent to do so within 30 days of
such discovery (a "Lessee Remediation Notice"), If Lessee timely delivers the
Lessee Remediation Notice, it shall (i) act promptly to investigate Hazardous
Substance issues, (ii) cooperate with Lessor and promptly furnish to Lessor
copies of the results of all tests performed by or for Lessee and (iii) promptly
remediate any such Hazardous Substances in accordance with applicable law and
this Lease. If no Lessee Remediation Notice is provided in timely fashion to
Lessor, Lessor shall have the option of addressing the resulting contamination
itself, in which case Lessee agrees to reimburse Lessor for all reasonable costs
and expenses incurred by Lessor to investigate, remediate, remove and dispose of
Hazardous Substances released, used or brought onto the Premises by Lessee (or
for Lessee by any third party) after December 21, 1999, and to restore the
Premises

                                       32

<PAGE>

following such activities. In the event Lessor elects to address the resulting
contamination itself, it shall do so In a manner which does not unreasonably
interfere with the activities of Lessee on the Premises. If Lessor does not
elect to address the resulting contamination, Lessee shall retain responsibility
for addressing the contamination, as set forth in Paragraph 6.2(c) of the Lease.
                                                  ----------------

     (c) Lessee Indemnification. Lessee and its successors and assigns shall
indemnify, defend by counsel reasonably acceptable to Lessor and hold Lessor,
its successors, assigns, agents, employees, lenders, and other tenants, if any,
harmless from and against any loss, liability, claim, cost, damage, or expense,
including but not limited to lost rents, judgments, penalties, settlement
payments, attorneys' fees and consultants' fees arising out of or involving any
Hazardous Substances released, used or brought onto the Premises by or for
Lessee or any third party after the Commencement Date. Lessee's obligations
shall include, but not be limited to, the effects of any contamination, whether
on the Premises or migrating off the Premises, injury to person, property or the
environment, created or caused by Lessee after the Commencement Date, and the
cost of investigation, removal, disposal, remediation, restoration and/or
abatement, and shall survive the expiration or termination of this Lease. No
termination or expiration of this Lease or any agreement entered into by Lessor
and Lessee shall release Lessee from its obligations under this Lease with
respect to such Hazardous Substances unless specifically so agreed by Lessor in
writing at the time of such agreement.

     (d) Remedial Facilities Easement. Lessee acknowledges that, in connection
with the Right of Entry Agreement, FMC and Lessor have entered into that certain
Easement Agreement and Memorandum of Right of Entry, dated December 21, 1999,
granting FMC various easements for remediation facilities on Premises (the
"Remedial Facilities Easement'). Lessee consents to and subordinates its
interest under this Lease to the easements granted under the Remedial Facilities
Easement. In addition, in the event additional investigation or remediation
facilities are required in the future, Lessee hereby consents to the
installation and operation of such facilities and agrees to subordinate its
interest under this Lease to any subsequent easement granted to FMC for such
purpose.

     (e) Utilities Easement. Lessee acknowledges that, in connection with the
Purchase Agreement, FMC and Lessor have entered into that certain Temporary

Property Tax Increases Caused by a Transfer. Lessor may transfer all or part of
its fee interest in the Premises in a transaction which will cause the ad
valorem property taxes on the Premises to increase. If so, Lessor shall so
notify Lessee at least six (6) months prior to the date of such transfer. If
Lessor does not give such notice in timely fashion, then Lessee shall not have
the obligation to pay any increase in such ad valorem property taxes caused by
the transfer for the period of time (i) beginning on the earlier of the date

the Lease, in the event that Lessee has notified Lessor pursuant to such
Paragraph of an obligation which Lessor must fulfill and, at that time, Lessor

Installations made to the Premises prior to the date hereof shall, for purposes
of any condemnation, be deemed to be owned solely by Lessor, (iii) all
Alterations and Utility Installations made to the Premises after the date hereof
shall, for purposes of any condemnation, be deemed to be owned solely by Lessee
and (iv) to the extent Lessor has any obligation to repair damage caused by any
condemnation, such obligation shall be limited to the proceeds recovered by
Lessor as a result of the condemnation.

     60. No Obligations for Prior Lease. Immediately prior to the date hereof
Lessee was a party to an Amended and Restated Lease Agreement dated as of
October 6, 1997 between FMC Corporation, as landlord, and Lessee, as tenant (as
amended to date, the "Prior Lease"). The interest in the Prior Lease of FMC
Corporation was assigned to Lessor. Lessee and Lessor hereby terminate the Prior
Lease. Except as provided below, Lessee acknowledges that the Prior Lease has
terminated, that neither Lessor nor FMC has any responsibility whatsoever for
the obligations of the landlord thereunder, and that the Prior Lease creates no
obligations between Lessor and Lessee. Without limiting the generality of the
foregoing, Lessee acknowledges that FMC has no obligation under paragraph 23 of
the Prior Lease. Notwithstanding the foregoing, Lessor retains and reserves the
right to obtain reimbursement of the first installment of 1999-2000 real estate
taxes for APN 230-46-053 and 230-46-032 from Lessee under the Prior Lease. Also,
Lessee shall be responsible for the second installment of real estate taxes for
APN 230-46-053, subject to such credit as Lessor receives from FMC Corporation.
Last, Lessee shall pay $1,530.77 which constitutes 0.78% of the second
installment of 1999-2000 taxes for APN 230-46-032 unless it has already paid the
same.

     61. Arbitration of Fair Rental Value. In the event the Fair Rental Value is
to be determined in accordance with this Paragraph 61, the judgment for the
award rendered in any arbitration may be entered in any court having
jurisdiction and shall be final and binding between the parties. The arbitration
shall be conducted and determined in the City and County of Santa Clara,
California, in accordance with the then prevailing rules of the American
Arbitration Association or its successor for arbitration of commercial disputes,
except to the extent that the procedures mandated by such rules shall be
modified as follows:

     (a) Either party may make demand for arbitration in writing, specifying
therein the name and address of the person to act as the arbitrator on its
behalf. The arbitrator shall be qualified as a real estate appraiser familiar
with the fair market rent of first class, improved industrial space in the Santa
Clara/San Jose area. Within fifteen (15) days after the service of the demand
for arbitration, the party not initiating arbitration shall give notice to the
other, specifying the name and address of the person designated by it to act as
arbitrator on its behalf, who shall be similarly qualified. If the party not
initiating arbitration fails to notify the other party of the failing party's
appointment of its arbitrator within the time specified above, then the
arbitrator appointed by the party initiating arbitration shall be the arbitrator
to determine the issue, shall determine Fair Rental Value within fifteen (15)
days after his appointment and shall promptly notify all parties of his
decision.

     (b) In the event that two arbitrators are chosen pursuant to paragraph (a)
above, the arbitrators so chosen shall, within fifteen (15) days after the
second arbitrator is appointed determine the Fair Rental Value. If they are
unable to agree within such fifteen (15) day period, they shall appoint a third
arbitrator who shall be a competent and impartial person with qualifications
similar to those required of the first two arbitrators. If they cannot agree
upon such appointment within seven (7) days after the expiration of the fifteen
(15) day period, the third arbitrator shall be selected by the parties
themselves, if they can agree within a further period of fifteen (15) days. If
they cannot, then either party, on behalf of both, may request appointment of
such a qualified person by the then chief judge of the United States District
Court having jurisdiction over the City of Santa Clara, acting in his private
and not in his official capacity, and the other party shall not raise any
question as to such judge's full power and jurisdiction to entertain the
application for and to make the appointment. The three arbitrators shall decide
the dispute, if it has not been previously resolved, by following the procedures
set forth below.

     (c) Where an issue cannot be resolved by agreement between the two
arbitrators selected by Lessor and Lessee, or settlement between the parties
during the course of arbitration, the issue shall be resolved by the three
arbitrators within fifteen (15) days of the appointment of the third arbitrator
in accordance with the following procedure. The arbitrator selected by each of
the parties shall state in writing his determination of the Fair

                                       34


<PAGE>

Rental Value supported by the reasons therefore with counterpart copies to each
party. The arbitrators shall arrange for a simultaneous exchange of such
proposed resolutions. The role of the third arbitrator shall be to select which
of the two proposed resolutions most closely approximates his determination of
Fair Rental Value. The third arbitrator shall have no right to propose a middle
ground or any modification of either of the two proposed resolutions. The
resolution he chooses as most closely approximating his determination shall
constitute the decision of the arbitrators and be final and binding upon the
parties.

     (d) In the event of a failure; refusal or inability of any arbitrator to
act, his successor shall be appointed by him, but in the case of the third
arbitrator, his successor shall be appointed in the same manner as provided for
appointment of the third arbitrator. The arbitrators shall decide the issue
within fifteen (15) days after the appointment of the third arbitrator. Any
decision in which the arbitrator appointed by Lessor and the arbitrator
appointed by Lessee concur shall be binding and conclusive upon the parties.
Each party shall pay the fee and expenses of its respective arbitrator and both
shall share the fee and expenses of the third arbitrator, if any, and the
attorneys' fees and expenses of counsel for the respective parties and of
witnesses shall be paid by the respective party engaging such counsel or calling
such witnesses. The arbitrators shall have the right to consult experts and
competent authorities to obtain factual information or evidence pertaining to a
determination of Fair Rental Value, but any such consultation shall be made in
the presence of both parties with full right on their party to cross-examine.
The arbitrators shall render their decision and award in writing with
counterpart copies to each party. The arbitrators shall have no power to modify
the provisions of this Lease.

     62. Improvement Allowance. On or before January 1, 2005, Lessor will
provide to Lessee an improvement allowance of up to $545,680 to enable Lessee to
improve the Premises by constructing Alterations or other permanent
Improvements. This improvement allowance will be paid to Losses by Lessor upon
receipt by Lessor of reasonable evidence that costs equal to the amount of the
improvement allowance have been incurred by Lessee for the foregoing purposes.
At Lessee's request, the amount of the improvement allowance will be paid
directly by Lessor to the contractors and others constructing the Alterations or
other permanent improvements.

     63. Covenant to Restrict Use of Property: Environmental Restriction. Lessee
acknowledges that the Premises are subject to that certain Covenant to Restrict
Use of Property: Environmental Restriction, dated August 1, 1996 and recorded on
October 1, 1996 in the official records of Santa Clara County, California as
document number 13466452 (the "Covenant to Restrict Use"). Lessee agrees to
comply with all restrictions on use of the Premises set forth in the Covenant to
Restrict Use. Pursuant to Section 3.04 of the Covenant to Restrict Use, the
following statement is hereby incorporated into this Lease: The land described
herein contains hazardous substances, as defined in Section 26316 of the
California Health and Safety Code, and petroleum hydrocarbons, and is subject to
the requirements of the Water Code and (the Covenant to Restrict Use), which
imposes certain covenants, conditions and environmental restrictions pursuant to
California Civil Code Section 1471 on use of the property described herein. The
provisions of the Covenant to Restrict Use are incorporated herein and made a
part hereof as if set forth in full. This statement is not a declaration that
any hazard exists.

     64. Certain Subletting.

     (a) In the event Lessee subleases fifty percent (50%) or more of the
leaseable area in that part of the Premises commonly known as "1205 Coleman"
(not including the property commonly known as "328 Brokaw" or "340 Brokaw"), or
subleases fifty percent (50%) or more of the rentable area in that portion of
the Promises commonly known as "328 Brokaw and 340 Brokaw, then Lessor shall
have the right to terminate this Lease as to such portion of the Premises, upon
thirty (30) days prior written notice to Lessee. The portion of the Premises
constituting each of said areas (that is,. "1205 Coleman" and "328/340 Brokawn")
is not precise, and Lessor and Lessee agree that they will act in good faith and
on a reasonable basis to determine how to separate these two portions of the
Premises should the need arise. In the event they cannot reach agreement within
thirty (30) days after Lessor's notice above, they shall resolve the dispute in
accordance with the arbitration procedures of Paragraph 61.
                                              ------------

     (b) In the event Lessee wishes to sublet any portion of the Premises it
shall first notify Lessor of (i) the proposed sublessee, (ii) the rent to be
charged and the other material terms of the proposed subletting and (iii) the
space to be sublet. In the event that the proposed subletting, if consummated,
would result in Lessee having thirty percent (30%) or more of the rentable
square footage of the Premises subject to subleases, then Lessor shall

                                       35

<PAGE>

have the right to terminate the Lease as to that portion of the Premises then
sublet and then proposed to be sublet, and thus "recapture" such portion, by
notifying Lessee to that effect within twenty (20) days after receiving Lessee's
notice. If Lessor so notifies Lessee, then effective thirty (30) days after the
receipt of the notice by Lessee, this Lease shall terminate as to said portion
of the Premises, Lessee shall deliver the same to Lessor in the condition
required upon termination of this Lease and Lessor shall have the right to use,
occupy and lease the same. In such event, Lessee shall provide Lessor and its
successors, assigns and lessees with reasonable access to said portion of the
Premises and with reasonable parking, and Lessor and Lessee shall cooperate with
one another to separate said portion of the Premises from that portion retained
by Lessee.

                      Notwithstanding the foregoing, in the event Lessee ever
proposes to sublet thirty percent (30%) or more of the rentable square
footage of the Promises ("30% Premises") in a single sublease and Lessor,
pursuant to its right set forth above, elects not to terminate the Lease as to
                                              ---
the 30% Premises, then if Lessee enters into such sublease the sublease of the
30% Premises shall not be deemed to be an outstanding sublease for purposes of
Lessor's right to recapture set forth above. Thus, if such sublease is entered
into, Lessor shall not have the right to terminate such sublease during its term
by reason of the lessor's rights in this Paragraph (b).

                  (c) In the event Lessor terminates this Lease as to a portion
of the Premises, as provided above, Lessor and Lessee shall treat such
termination as if this Lease had terminated at the end of the term as to such
portion, and thereafter the Base Rent and other charges hereunder shall be
prorated on the basis that the rentable area of that portion of the Premises
which is not terminated bears to the rentable area of the entire Premises on the
date hereof. If Lessor elects to so terminate, it shall not charge Lessee any
additional sum for so doing.

                  (d) In the event Lessee elects to sublet all or a portion of
the Premises for an amount which exceeds the amount of the Base Rent and Real
Property Taxes fairly allocable to such portion (the amount fairly allocable
shall be the pro rate portion of the Base Rent, based on the square footage
sublet), then Lessee shall pay to Lessor sixty percent (60%) of the amount by
which the rent and other consideration which Lessee receives on account of the
subletting exceeds the sum of (i) the Base Rent and other charges Lessee pays
Lessor for such portion and (ii) Lessee's reasonable out-of-pocket expenses of
subletting.

                  65. Lessor Rights on Assignment. In the event Lessee wishes to
assign its interest in the Lease, it shall first notify Lessor of (i) the
proposed assignee, (ii) the material terms of the proposed assignment, including
the consideration therefore, and (iii) the effective date proposed for the
assignment. Lessor shall have the right to terminate this Lease, and thus
"recapture" the Premises, by notifying Lessee to that affect within twenty (20)
days after receiving Lessee's notice. If Lessor so notifies Lessee, then
effective thirty (30) days after the receipt of the notice by Lessee, this Lease
shall terminate and Lessee shall deliver the Premises to Lessor in the condition
required upon termination of this Lease. Notwithstanding the foregoing
provisions of this Paragraph 65, Lessor shall not have the right to terminate
this Lease or "recapture" the Premises in the event Lessee's assignment of this
Lease is pursuant to a merger of Lessee or the sale by Lessee of all or
substantially all of it assets.

                  In the event Lessor does not exercise its option to terminate
the Lease and the Premises, and Lessee assigns its interest in the Lease as
proposed in its notice to Lessor, then Lessee shall pay to Lessor, when it
receives the same, sixty percent (60%) of the amount by which the rent and other
consideration which Lessee receives on account of the assignment exceeds the sum
of (i) the Base Rent and other charges Lessee pays Lessor under the Lease and
(iii) Lessee's reasonable out-of-pocket expenses incurred in connection with the
assignment. In the event Lessee receives a lump sum payment on or about the date
of the assignment, for purposes of determining the amount in clause (i) above,
the Base Rent and other charges payable under the Lease shall be discounted to
present value in the manner contemplated in Section 13.2(a) of the Lease.
                                            ---------------

                  66. Financial Reporting. Concurrently herewith Lessee has
                      -------------------
delivered to Lessor a letter in the form of Exhibit C sent to Lessor by United
                                            ---------
Defense, Inc. ("UDI"), which controls United Defense, L.P. No later than April 1

UDI directed to Lessor in the form of Exhibit C but with respect to its fiscal

year most recently ended, to the effect set forth in Exhibit C for such year; or
                                                     ---------
(ii) a balance sheet, income statement and statement of changes in financial
condition for Lessee for the fiscal year of Lessee most recently ended,
unaudited but certified by Lessee's chief financial officer as true, correct and

                  67.   Certain Distributions to UDI. Lessee shall promptly
                        ----------------------------
notify Lessor if, at any time during the Term of the Lease, Lessee transfers
twenty-five percent (25%) or more (determined by value) of its assets to UDI or
an entity controlled by or under common control with UDI. Within forty-five (45)
days thereafter Lessor shall have the right by notice to Lessee and UDI,

                  67.1  if at that time UDI is a corporation which is filing
public reports under Section 12(g) of the Securities Exchange Act of 1934, then
to cause UDI to become the Lessee under this Lease and to assume all of the
obligations of Lessee hereunder in a form, and by documents, reasonably
acceptable to Lessor. If Lessor makes the election under this Section 67.1,
                                                              ------------
Lessor shall release United Defense, L.P. from all of its obligations under the
Lease from and after the date when UDI becomes the Lessee hereunder; and

                  67.2  if at that time UDI is not a corporation which is filing
public reports under Section 12(g) of the Securities Exchange Act of 1934, then
to cause UDI to become an additional Lessee hereunder, having joint and several
liability with United Defense, L.P., and to cause UDI to assume all of the
obligations of Lessee hereunder in a form, and by documents, reasonably
acceptable to Lessor. If Lessor makes the election under this Section 67.2,
                                                              ------------
United Defense, L.P. shall not be released from any of its obligations
hereunder.

                  No distribution of assets from Lessee to UDI or an entity
controlled by or under common control with UDI shall give Lessor any right to
"recapture" the Premises as provided in Paragraph 65 above.

                  IN WITNESS WHEREOF, Lessor and Lessee have executed this
Addendum as of the date first above written.
