The tenant would be the sublessor and the third party would be the sublessee. Besides preparing a sublease, both parties will want to review the provisions for assignment or subletting in the original lease agreement between the landlord and the sublessor.
  • Sublease Agreement. Tenants of residential property should prepare a sublease agreement if they are seeking to sublease a room or the entire apartment or house to a third party. All parties should review the original lease agreement to see if there are any restrictions on subletting or assigning the premises.
  • Triple Net Lease. Triple net leases are a type of commercial leases where the tenant has to pay for property taxes, insurance, utilities, and maintenance, in addition to the monthly rent.
  • Office Space Lease. When renting an office space, tenants should understand the amount of the rent and duration of the lease.

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 square footage set forth in this Lease, or that
may have been used in calculating rental, is an approximation which Lessor and
Lessee agree is reasonable and the rental based thereon is not subject to
revision whether or not the actual square footage is more or less.

  2.2 CONDITION. Lessor shall deliver the Premises to Lessee clean and free of
debris on the Commencement Date and warrants to Lessee that the existing
plumbing, fire sprinkler system, lighting, air conditioning, heating, and
loading doors, if any, in the Premises, other than those constructed by Lessee,
shall be in good operating condition on the Commencement Date. If a
non-compliance with said warranty exists as of the Commencement Date, Lessor
shall, except as otherwise provided in this Lease, promptly after receipt of
written notice from Lessee setting forth with specificity the nature and extent
of such non-compliance, rectify same at Lessor's expense. If Lessee does not
give Lessor written notice of a non-compliance with this warranty within thirty
(30) days after the Commencement Date, correction of that non-compliance shall
be the obligation of Lessee at Lessee's sole cost and expense.

  2.3 COMPLIANCE WITH COVENANTS, RESTRICTIONS AND BUILDING CODE. Lessor warrants
to Lessee that the improvements on the Premises comply with all applicable
covenants or restrictions of record and applicable building codes, regulations
and ordinances in effect on the Commencement Date. Said warranty does not apply
to the use to which Lessee will put the Premises or to any Alterations or
Utility Installations (as defined in Paragraph 7.3(a)) made or to be made by
Lessee. If the Premises do not comply with said warranty, Lessor shall, except
as otherwise provided in this Lease, promptly after receipt of written notice
from Lessee setting forth with specificity the nature and extent of such
non-compliance, rectify the same at Lessor's expense. If Lessee does not give
Lessor written notice of a non-compliance with this warranty within six (6)
months following the Commencement Date, correction of that non-compliance shall
be the obligation of Lessee at Lessee's sole cost and expense.

  2.4 ACCEPTANCE OF PREMISES. Lessee hereby acknowledges: (a) that it has been
advised by the Brokers to satisfy itself with respect to the condition of the
Premises (including but not limited to the electrical and fire sprinkler
systems, security, environmental aspects, compliance with Applicable Law, as
defined in Paragraph 6.3) and the present and future suitability of the Premises
for Lessee's intended use, (b) that Lessee has made such investigation as it
deems necessary with reference to such matters and assumes all responsibility
therefor as the same relate to Lessee's occupancy of the Premises and/or the
term of this Lease, and (c) that neither Lessor, nor any of Lessor's agents, has
made any oral or written representations or warranties with respect to the said
matters other than as set forth in this Lease.

  2.5 LESSEE PRIOR OWNER/OCCUPANT. The warranties made by Lessor in this
Paragraph 2 shall be of no force or effect if immediately prior to the date set
forth in Paragraph 1.1 Lessee was the owner or occupant of the Premises. In such
event, Lessee shall, at Lessee's sole cost and expense, correct any
non-compliance of the Premises with said warranties.

Lease are as specified in Paragraph 1.3.

  3.3 DELAY IN POSSESSION. IF for any reason Lessor cannot deliver possession of
the Premises to Lessee as agreed herein by the Early Possession Date, if one is
specified in Paragraph 1.4, or, if no Early Possession Date is specified, by the
Commencement Date, Lessor shall not be subject to any liability therefor, nor
shall such failure affect the validity of this Lease, or the obligations of
Lessee hereunder, or extend the term hereof, but in such case, Lessee shall not,
except as otherwise provided herein, be obligated to pay rent or perform any
other obligation of Lessee under the terms of this Lease until Lessor delivers
possession of the Premises to Lessee. If possession of the Premises is not
delivered to Lessee within sixty (60) days after the Commencement Date, Lessee
may, at its option, by notice in writing to Lessor within ten (10) days
thereafter, cancel this Lease, in which event the Parties shall be discharged
from all obligations hereunder; provided, however, that if such written notice
by Lessee is not received by Lessor within said ten (10) day period, Lessee's
right to cancel this Lease shall terminate and be of no further force or effect.
Except as may be otherwise provided, and regardless of when the term actually
commences, if possession is not tendered to Lessee when required by this Lease
and Lessee does not terminate this Lease, as aforesaid, the period free of the
obligation to pay Base Rent, if any, that Lessee would otherwise have enjoyed
shall run from the date of delivery of possession and continue for a period
equal to what Lessee would otherwise have enjoyed under the terms hereof, but
minus any days of delay caused by the acts, changes or omissions of Lessee.

4. RENT.

  4.1 BASE RENT. Lessee shall cause payment of Base Rent and other rent or
charges, as the same may be adjusted from time to time, to be received by Lessor
in lawful money of the United States, without offset or deduction, on or before
the day on which it is due under the terms of this Lease. Base Rent and all
other rent and charges for any period during the term hereof which is for less
than one (1) full calendar month shall be prorated based upon the actual number
of days of the calendar month involved. Payment of Base Rent and other charges
shall be made to Lessor at its address stated herein or to such other persons or
at such other addresses as Lessor may from time to time designate in writing to
Lessee.

5. SECURITY DEPOSIT. Lessee shall deposit with Lessor upon execution hereof 
the Security Deposit set forth in Paragraph 1.7 as security for Lessee's 
faithful performance of Lessee's obligations under this Lease. If Lessee 
fails to pay Base Rent or other rent or charges due hereunder, or otherwise 
Defaults under this Lease (as defined in Paragraph 13.1), Lessor may use, 
apply or retain all or any portion of said Security Deposit for the payment 
of any amount due Lessor or to reimburse or compensate Lessor for any 
liability, cost, expense, loss or damage (including attorneys' fees) which 
Lessor may suffer or incur by reason thereof. If Lessor uses or applies all 
or any portion of said Security Deposit, Lessee shall within ten (10) days 
after written request therefor deposit moneys with Lessor sufficient to 
restore said Security Deposit to the full amount required by this Lease. Any 
time the Base Rent increases during the term of this Lease, Lessee shall, 
upon written request from Lessor, deposit additional moneys with Lessor 
sufficient to maintain the same ratio between the Security Deposit and the 
Base Rent as those amounts are specified in the Basic Provisions.  Lessor 
shall not be required to keep all or any part of the Security Deposit 
separate from its general accounts. Lessor shall, at the expiration or 
earlier termination of the term hereof and after Lessee has vacated the 
Premises, return to Lessee (or, at Lessor's option, to the last assignee, if 
any, of Lessee's interest herein), that portion of the Security Deposit not 
used or applied by Lessor. Unless otherwise expressly agreed in writing by 
Lessor, no part of the Security Deposit shall be considered to be held in 
trust, to bear interest or other increment for its use, or to be prepayment 
for any moneys to be paid by Lessee under this Lease.

6. USE.

  6.1 USE. Lessee shall use and occupy the Premises only for the purposes set
forth in Paragraph 1.8, or any other use which is comparable thereto, and for no
other purpose. Lessee shall not use or permit the use of the Premises in a
manner that creates waste or a nuisance, or that disturbs owners and/or
occupants of, or causes damage to, neighboring premises or properties. Lessor
hereby agrees to not unreasonably withhold or delay its consent to any written
request by Lessee, Lessees assignees or subtenants, and by prospective assignees
and subtenants of the Lessee, its assignees and subtenants, for a modification
of said permitted purpose for which the premises may be used or occupied, so
long as the same will not impair the structural integrity of the improvements on
the Premises, the mechanical or electrical systems therein, is not significantly
more burdensome to the Premises and the improvements thereon, and is otherwise
permissible pursuant to this Paragraph 6. If Lessor elects to withhold such
consent, Lessor shall within thirty (30) business days give a written
notification of same, which notice shall include an explanation of Lessor's
reasonable objections to the change in use.

  6.2 HAZARDOUS SUBSTANCES. See Addendum, Paragraph 6

     (a) REPORTABLE USES REQUIRE CONSENT. The term "HAZARDOUS SUBSTANCE" as 
used in this Lease shall mean any product, substance, chemical, material or 
waste whose presence, nature, quantity and/or intensity of existence, use, 
manufacture, disposal, transportation, spill, release or effect, 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 liability of Lessor to any 
governmental agency or third party under any applicable statute or common law 
theory. Hazardous Substance shall include, but not be limited to, 
hydrocarbons, petroleum, gasoline, crude oil or any products, by-products or 
fractions thereof. Lessee shall not engage in any activity in, on or about 
the Premises which constitutes a Reportable Use (as hereinafter defined) of 
Hazardous Substances without the express prior written consent of Lessor and 
compliance in a timely manner (at Lessee's sole cost and expense) with all 
Applicable Law (as defined in Paragraph 6.3). "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. Reportable Use shall also include Lessee's being 
responsible for the presence in, on or about the Premises of a Hazardous 
Substance with respect to which any Applicable Law requires that a notice be 
given to persons entering or occupying the Premises or neighboring 
properties. Notwithstanding the foregoing, Lessee may, without Lessor's prior 
consent, but in compliance with all Applicable Law, use any ordinary and 
customary materials reasonably required to be used by Lessee in the normal 
course of Lessee's business permitted on the Premises, so long as such use is 
not a Reportable Use and does not expose the Premises or neighboring 
properties to any meaningful risk of contamination or damage or expose Lessor 
to any liability therefor. In addition, Lessor may (but without any 
obligation to do so) condition its consent to the use or presence of any 
Hazardous Substance, activity or storage tank by Lessee upon Lessee's giving 
Lessor such additional assurances as Lessor, in its reasonable discretion, 
deems necessary to protect itself, the public, the Premises and the 
environment against damage, contamination or injury and/or liability 
therefrom or therefor, including, but not limited to, the installation (and 
removal on or before Lease expiration or earlier termination) of reasonably 
necessary protective modifications to the Premises (such as concrete 
encasements) and/or the deposit of an additional Security Deposit under 
Paragraph 5 hereof.

     (b) DUTY TO INFORM LESSOR. If Lessee knows, or has reasonable cause to
believe, that a Hazardous Substance, or a condition involving or resulting from
same, has come to be located in, on, under or about the Premises, other than as
previously consented to by Lessor, Lessee shall immediately give written notice
of such fact to Lessor. Lessee shall also immediately give Lessor a copy of any
statement, report, notice, registration, application, permit, business plan,
license, claim, action or proceeding given to, or received from, any
governmental authority or private party, or persons entering or occupying the
Premises, concerning the presence, spill, release, discharge of, or exposure to,
any Hazardous Substance or contamination in, on, or about the Premises,
including but not limited to all such documents as may be involved in any
Reportable Uses involving the Premises.

     (c) INDEMNIFICATION. Lessee's obligations under this Paragraph 6 shall
include, but not be limited to, the effects of any contamination or injury to
person, property or the environment and the cost of investigation (including
consultant's and attorney's fees and testing), removal, remediation, restoration
and/or abatement thereof, or of any contamination therein involved, and shall
survive the expiration or earlier termination of this Lease. No termination,
cancellation or release agreement entered into by Lessor and Lessee shall
release Lessee from its obligations under this Lease with respect to Hazardous
Substances or storage tanks, unless specifically so agreed by Lessor in writing
at the time of such agreement.

  6.3 LESSEE'S COMPLIANCE WITH LAW. Except as otherwise provided in this Lease,
Lessee, shall, at Lessee's sole cost and expense, fully, diligently and in a
timely manner, comply with all "APPLICABLE LAW," which term is used in this
Lease to include all laws, rules, regulations, ordinances, directives,
covenants, easements and restrictions of record, permits, the requirements of
any applicable fire insurance underwriter or rating bureau, and the
recommendations of Lessor's engineers and/or consultants, relating in any manner
to the Premises (including but not limited to matters pertaining to (i)
industrial hygiene, (ii) environmental conditions on, in, under or about the
Premises, including soil and groundwater conditions, and (iii) the use,
generation, manufacture, production, installation, maintenance, removal,
transportation, storage, spill or release of any Hazardous Substance or storage
tank), now in effect or which may hereafter come into effect, and whether or not
reflecting a change in policy from any previously existing policy. Lessee shall,
within five (5) days after receipt of Lessor's written request, provide Lessor
with copies of all documents and information, including, but not limited to,
permits, registrations, manifests, applications, reports and certificates,
evidencing Lessee's compliance with any Applicable Law 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 failure by Lessee or the
Premises to comply with any Applicable Law.

  6.4 INSPECTION; COMPLIANCE. Lessor and Lessor's Lender(s) (as defined in
Paragraph 8.3(a)) shall have the right to enter the Premises at any time, in the
case of an emergency, and otherwise at reasonable times, for the purpose of
inspecting the condition of the Premises and for verifying compliance by Lessee
with this Lease and all Applicable Laws (as defined in Paragraph 6.3), and to
employ experts and/or consultants in connection therewith and/or to advise
Lessor with respect to Lessee's activities, including but not limited to the
installation, operation, use, monitoring, maintenance, or removal of any
Hazardous Substance or storage tank on or from the Premises. The costs and
expenses of any such inspections shall be paid by the party requesting same,
unless a Default or Breach of this Lease, violation of Applicable Law, or a
contamination, caused or materially contributed to by Lessee is found to exist
or be imminent, or unless the inspection is requested or ordered by a
governmental authority as the result of any such existing or imminent violation
or contamination. In any such case, Lessee shall upon request reimburse Lessor
or Lessor's Lender, as the case may be, for the costs and expenses of such
inspections.

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, without limiting the generality of the
foregoing, all equipment or facilities serving the Premises, such as plumbing,
heating, air conditioning, ventilating, electrical, lighting facilities,
boilers, fired or unfired pressure vessels, fire sprinkler and/or standpipe and
hose or other automatic fire extinguishing system, including fire alarm and/or

signs, sidewalks and parkways located in, on, about, or adjacent to the
Premises. Lessee shall not cause or permit any Hazardous Substance to be spilled
or released in, on, under or about the Premises (including through the plumbing
or sanitary sewer system) and shall promptly, at Lessee's expense, take all
investigatory and/or remedial action reasonably recommended, whether or not
formally ordered or required, for the cleanup of any contamination of, and for
the maintenance, security and/or monitoring of the Premises, the elements
surrounding same, or neighboring properties, that was caused or materially
contributed to by Lessee, or pertaining to or involving any Hazardous Substance
and/or storage tank brought onto the Premises by or for Lessee or under its
control, Lessee, in keeping the Premises in good order, condition and repair,
shall exercise and perform good maintenance practices. 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. If Lessee occupies the Premises for seven (7) years or
more, Lessor may require Lessee to repaint the exterior of the buildings on the
Premises as reasonably required, but not more frequently than once every
seven (7) years.

    (b) Lessee shall, at Lessee's sole cost and expense, procure and maintain

contained in Paragraphs 2.2 (relating to condition of the Premises), 2.3
(relating to compliance with covenants, restrictions and building code), 9

the Premises), it is intended by the Parties hereto that Lessor have no
obligation, in any manner whatsoever, to repair and maintain the Premises, the
improvements located thereon, or the equipment therein, whether structural or
non structural, all of which obligations are intended to be that of the Lessee
under Paragraph 7.1 hereof. 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. Lessee and Lessor expressly waive the benefit of any
statute now or hereafter in effect to the extent it is inconsistent with the
terms of this Lease with respect to, or which affords Lessee the right to make
repairs at the expense of Lessor or to terminate this Lease by reason of any
needed repairs.

    (a) DEFINITIONS; CONSENT REQUIRED. The term "UTILITY INSTALLATIONS" is used
in this Lease to refer to all carpeting, window coverings, air lines, power
panels, electrical distribution, security, fire protection systems,
communication systems, lighting fixtures, heating, ventilating, and air
conditioning equipment, plumbing, and fencing in, on or about 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 on the Premises from that which
are provided by Lessor under the terms of this Lease, 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 as defined
in Paragraph 7.4(a). Lessee shall not make any Alterations or Utility
Installations in, on, under or about the Premises without Lessor's prior written
consent. Lessee may, however, make non-structural Utility Installations to the
interior of the Premises (excluding the roof), as long as they are not visible
from the outside, do not involve puncturing, relocating or removing the roof or
any existing walls, and the cumulative cost thereof during the term of this
Lease as extended does not exceed $25,000.

    (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 proposed detailed plans. All consents given by
Lessor, whether by virtue of Paragraph 7.3(a) or by subsequent specific consent,
shall be deemed conditioned upon: (i) Lessee's acquiring all applicable permits
required by governmental authorities, (ii) the furnishing of copies of such
permits together with a copy of the plans and specifications for the Alteration
or Utility Installation to Lessor prior to commencement of the work thereon, and
(iii) the compliance by Lessee with all conditions of said permits in a prompt
and expeditious manner. Any Alterations or Utility Installations by Lessee
during the term of this Lease shall be done in a good and workmanlike manner,
with good and sufficient materials, and in compliance with all Applicable Law.
Lessee shall promptly upon completion thereof furnish Lessor with as-built plans
and specifications therefor. Lessor may (but without obligation to do so)
condition its consent to any requested Alteration or Utility Installation that
costs $10,000 or more upon Lessee's providing Lessor with 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 under Paragraph 36 hereof.

    (c) INDEMNIFICATION. Lessee shall pay, when due, all claims for labor or
materials furnished or alleged to have been furnished to or for Lessee at or for
use on the Premises, which claims are or may be secured by any mechanics' or
materialmen's lien against the Premises or any interest therein. Lessee shall
give Lessor not less than ten (10) days' notice prior to the commencement of any
work in, on or about the Premises, and Lessor shall have the right to post
notices of non-responsibility in or on the Premises as provided by law. If
Lessee shall, in good faith, 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 against the
Lessor or the Premises. If Lessor shall require, Lessee shall furnish to Lessor
a surety bond satisfactory to Lessor 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, as required by law for the holding of the
Premises free from the effect of such lien or claim. In addition, Lessor may
require Lessee to pay Lessor's attorney's fees And costs in participating in
such action if Lessor shall decide it is to its best interest to do so.

    7.4 OWNERSHIP; REMOVAL; SURRENDER; AND RESTORATION.

the owner thereof as hereinafter provided in this Paragraph 7.4, all Alterations
and Utility Additions made to the Premises by Lessee shall be the property of
and owned by Lessee, but considered a part of the Premises. Lessor may, at any
time and at its option, elect in writing to Lessee to be the owner of all or any
specified part of the Lessee Owned Alterations and Utility Installations. Unless
otherwise instructed per subparagraph 7.4(b) hereof, all Lessee Owned
Alterations and Utility Installations shall, at the expiration or earlier
termination of this Lease, become the property of Lessor and remain upon and be
surrendered by Lessee with the Premises.

    (b) REMOVAL. Unless otherwise agreed in writing, Lessor may require that any
or all Lessee Owned Alterations or Utility Installations be removed by the
expiration or earlier termination of this Lease, notwithstanding their
installation may have been consented to by Lessor. 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 of Lessor.

    (c) SURRENDER/RESTORATION. Lessee shall surrender the Premises by the end of
the last day of the Lease term or any earlier termination date, with all of the
improvements, parts and surfaces thereof clean and free of debris and in good
operating order, condition and state of repair, ordinary wear and tear excepted.

would have been prevented by good maintenance practice or by Lessee performing
all of its obligations under this Lease. Except as otherwise agreed or specified

occasioned by the installation, maintenance or removal of Lessee's Trade
Fixtures, furnishings, equipment, and Alterations and/or Utility Installations,

limits of said insurance required by this Lease or as carried by Lessee shall
not, however, limit the liability of Lessee nor relieve Lessee of any obligation
hereunder. All insurance to be 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. In the event Lessor is the Insuring Party, Lessor shall
also maintain liability insurance described in Paragraph 8.2(a), above, 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 during the term of this lease a policy or policies in the name of 
Lessor, with loss payable to Lessor and to the holders of any mortgages, 
deeds of trust or ground leases on the Premises ("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 including any costs necessary to cause the Premises to comply with law 
or the amount required by Lenders.  If the coverage is available and 
commercially appropriate, such policy or policies shall insure against all 
risks of direct physical loss or damage (except the perils of flood and/or 
earthquake unless required by a Lender), including coverage for any 
additional costs resulting from debris removal and reasonable amounts of 
coverage for the enforcement of any ordinance or law regulating the 
reconstruction or replacement of any undamaged sections of the Premises 
required to be demolished or removed by reason of the enforcement of any 
building, zoning, safety or land use laws as the result of a covered cause of 
loss. Said policy or policies shall also contain an agreed valuation 
provision in lieu of any coinsurance clause, waiver of subrogation, and 
inflation guard protection causing an increase in the annual property 
insurance coverage amount by a factor of not less than the adjusted U.S. 
Department of Labor Consumer Price Index for all Urban Consumers for the city 
nearest to where the Premises are located. If such insurance coverage has a 
deductible clause, the deductible amount shall not exceed $1,000 per 
occurrence, and Lessee shall be liable for such deductible amount in the 
event of an Insured Loss, as defined in Paragraph 9.1(c).

     (b) RENTAL VALUE. The Insuring Party shall, in addition, obtain and keep in
force during the term of this Lease a policy or policies in the name of Lessor,
with loss payable to Lessor and Lender(s), insuring the loss of the full rental
and other charges payable by Lessee to Lessor under this Lease for one (1) year
(including all real estate taxes, insurance costs, and any scheduled rental
increases). Said insurance shall provide that in the event the Lease is
terminated by reason of an insured loss, the period of indemnity for such
coverage shall be extended beyond the date of the completion of repairs or
replacement of the Premises, to provide for one full year's loss of rental
revenues from the date of any such loss. Said insurance shall contain an agreed
valuation provision in lieu of any coinsurance clause, and the amount of
coverage shall be adjusted annually to reflect the projected rental income,
property taxes, insurance premium costs and other expenses, if any, otherwise
payable by Lessee, for the next twelve (12) month period. Lessee shall be liable
for any deductible amount in the event of such loss.

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

     (d) TENANT'S IMPROVEMENTS. If the Lessor is the Insuring Party, the Lessor
shall not be required to insure Lessee Owned Alterations and Utility
Installations unless the item in question has become the property of Lessor
under the terms of this Lease. If Lessee is the Insuring Party, the policy
carried by Lessee under this paragraph 8.3 shall insure Lessee Owned Alterations
and Utility Installations.

  8.4 LESSEE'S PROPERTY INSURANCE. Subject to the requirements of Paragraph 8.5,
Lessee at its cost shall either by separate policy or, at Lessor's option, by
endorsement to a policy already carried, maintain insurance coverage on all of
Lessee's personal property, Lessee Owned Alterations and Utility Installations
in, on, or about the Premises similar in coverage to that carried by the
Insuring Party under Paragraph 8.3. Such insurance shall be full replacement
cost coverage with a deductible of not to exceed $1,000 per occurrence. The
proceeds from any such insurance shall be used by Lessee for the replacement of
personal property or the restoration of Lessee Owned Alterations and Utility
Installations. Lessee shall be the Insuring Party with respect to the insurance
required by this Paragraph 8.4 and shall provide Lessor with written evidence
that such insurance is in force.

  8.5 INSURANCE POLICIES. Insurance required hereunder shall be in companies
duly licensed 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, or such other rating as may be required by a Lender having a lien
on the Premises, as set forth in the most current issue of "Best's Insurance
Guide." Lessee shall not do or permit to be done anything which shall invalidate
the insurance policies referred to in this Paragraph 8. If Lessee is the
Insuring Party, Lessee shall cause to be delivered to Lessor certified copies of
policies of such insurance or certificates evidencing the existence and amounts
of such insurance with the insureds and loss payable clauses as required by this
Lease. No such policy shall be cancellable or subject to modification except
after thirty (30) days prior written notice to Lessor. Lessee shall at least
thirty (30) days prior to the expiration of such policies, furnish Lessor with
evidence of renewals or "insurance binders" evidencing renewal thereof, or
Lessor may order such insurance and charge the cost thereof to Lessee, which
amount shall be payable by Lessee to Lessor upon demand. If the Insuring Party
shall fail to procure and maintain the insurance required to be carried by the
Insuring Party under this Paragraph 8, the other Party may, but shall not be
required to, procure end maintain the same, but at Lessee's expense.

  8.6 WAIVER OF SUBROGATION.  See Addendum, Paragraph 7

  8.7 INDEMNITY. Except for Lessor's negligence and/or breach of express
warranties, 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,
costs, liens, judgments, penalties, permits, attorney's and consultants fees,
expenses and/or liabilities arising out of, involving, or in dealing with, the
occupancy of the Premises by Lessee, the conduct of Lessee's business, any act,
omission or neglect of Lessee, its agents, contractors, employees or invitees,
and out of any Default or Breach by Lessee in the performance in a timely manner
of any obligation on Lessee's part to be performed under this Lease. The
foregoing shall include, but not be limited to, the defense or pursuit of any
claim or any action or proceeding involved therein, and whether or not (in the
case of claims made against Lessor) litigated and/or reduced to judgment, and
whether well founded or not. In case any action or proceeding be brought against
Lessor by reason of any of the foregoing matters, Lessee upon notice from Lessor
shall defend the same at Lessee's expense by counsel reasonably satisfactory to
Lessor and Lessor shall cooperate with Lessee in such defense. Lessor need not
have first paid any such claim in order to be so indemnified.

  8.8 EXEMPTION OF LESSOR FROM LIABILITY. Lessor shall not be liable for injury
or damage to the person or goods, wares, merchandise or other property of
Lessee, Lessee's employees, contractors, invitees, customers, or any other
person in or about the Premises, whether such damage or injury is caused or
results from earthquake, flood, fire, steam, electricity, gas, water or rain, or
from the breakage, leakage, obstruction or other defects of pipes, fire
sprinklers, wires, appliances, plumbing, air conditioning or lighting fixtures,
or from any other cause, whether the said injury or damage results from
conditions arising upon the Premises or upon other portions of the building of
which the Premises are a part, or from other sources or places, and regardless
of whether the cause of such damage or injury or the means of repairing the same
is accessible or not. Lessor shall not be liable for any damages arising from
any act or neglect of any other tenant of Lessor. Notwithstanding Lessor's
negligence or breach of this lease, Lessor shall under no circumstances be
liable for injury to Lessee's business or for any loss of income or profit
therefrom.

9. DAMAGE OR DESTRUCTION.

  9.1 DEFINITIONS.

    (a) "PREMISES PARTIAL DAMAGE" shall mean damage or destruction to the
improvements on the Premises, other than Lessee Owned Alterations and Utility
Installations, the repair cost of which damage or destruction is less than 50%
of the then Replacement Cost of the Premises immediately prior to such damage or
destruction, excluding from such calculation the value of the lend and Lessee
Owned Alterations and Utility Installations.

    (b) "PREMISES TOTAL DESTRUCTION" shall mean damage or destruction to the
Premises, other than Lessee Owned Alterations and Utility Installations. The
repair cost of which damage or destruction is 50% or more of the then
replacement cost of the Premises immediately prior to such damage or
destruction, excluding from such calculation the value of the land end Lessee
Owned Alterations and Utility Installations.

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

    (d) "REPLACEMENT COST" shall mean the cost to repair or rebuild the
improvements owned by Lessor at the time of the occurrence to their condition
existing immediately prior thereto, including demolition, debris removal and
upgrading required by the operation of applicable building codes, ordinances or
laws, and without deduction for depreciation.

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

    9.2 PARTIAL DAMAGE-INSURED LOSS. If a Premises Partial Damage that is an
Insured Loss occurs, then Lessor shall, at Lessor's expense, repair such damage
(but not Lessee's Trade Fixtures or Lessee Owned Alterations and Utility
installations) as soon as reasonably possible and this Lease shall continue in
full force and effect; provided, however, that Lessee shall, at Lessor's
election, make the repair of any damage or destruction the total cost to repair
of which is $10,000 or less, and, in such event, Lessor shall make the insurance
proceeds available to Lessee on a reasonable basis for that purpose.
Notwithstanding the foregoing, if the required insurance was not in force or the
insurance proceeds are not sufficient to effect such repair, the Insuring Party
shall promptly contribute the shortage in proceeds as and when required to
complete said repairs. In the event, however, the shortage in proceeds was due
to the fact that, by reason of the unique nature of the improvements, full
replacement cost insurance coverage was not commercially reasonable and
available, Lessor shall have no obligation to pay for the shortage in insurance
proceeds or to fully restore the unique aspects of the Premises unless Lessee
provides Lessor with the funds to cover same, or adequate assurance thereof,
within ten (10) days following receipt of written notice of such shortage and
request therefor. If Lessor receives said funds or adequate assurance hereof
within said ten (10) day period, the party responsible for making the repairs
shall complete them as soon as reasonably possible and this Lease shall remain
in full force and effect. If Lessor does not receive such funds or assurance
within said period, Lessor may nevertheless elect by written notice to Lessee
within ten (10) days thereafter to make such restoration and repair as is
commercially reasonable with Lessor paying any shortage in proceeds, in which
case this Lease shall remain in full force and effect. If in such case Lessor
does not so elect, then this Lease shall terminate sixty (60) days following the
occurrence of the damage or destruction. Unless otherwise agreed, Lessee shall
in no event have any right to reimbursement from Lessor for

NET                                     PAGE 4
<PAGE>

any funds contributed by Lessee to repair any such damage or destruction.
Premises Partial Damage due to flood or earthquake shall be subject to Paragraph
9.3 rather than Paragraph 9.2, notwithstanding that there may be some insurance
coverage, but the net proceeds of any such insurance shall be made available for
the repairs if made by either Party.

  9.3 PARTIAL DAMAGE-UNINSURED LOSS. If a Premises Partial Damage that is not an
Insured Loss occurs, unless caused by a negligent or willful act of Lessee (in
which event Lessee shall make the repairs at Lessee's expense and this Lease
shall continue in full force and effect, but subject to Lessor's rights under
Paragraph 13), Lessor may at Lessor's option, 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) give written notice to Lessee within
thirty (30) days after receipt by Lessor of knowledge of the occurrence of such
damage of Lessor's desire to terminate this Lease as of the date sixty (60) days
following the giving of such notice.  In the event Lessor elects to give such
notice of Lessor's intention to terminate this Lease, Lessee shall have the
right within ten (10) days after the receipt of such notice to give written
notice to Lessor of Lessee's commitment to pay for the repair of such damage
totally at Lessee's expense and without reimbursement from Lessor. Lessee shall
provide Lessor with the required funds or satisfactory assurance thereof within
thirty (30) days following Lessee's said commitment. In such event this Lease
shall continue in full force and effect, and Lessor shall proceed to make such
repairs as soon as reasonably possible and the required funds are available. If
Lessee does not give such notice and provide the funds or assurance thereof
within the times specified above, this Lease shall terminate as of the date
specified in Lessor's notice of termination.

  9.4 TOTAL DESTRUCTION. Notwithstanding any other provision hereof, if a
Premises Total Destruction occurs (including any destruction required by any
authorized public authority), this Lease shall terminate sixty (60) days
following the date of such Premises Total Destruction, whether or not the damage
or destruction is an Insured Loss or was caused by a negligent or willful act of
Lessee. In the event, however, that the damage or destruction was caused by
Lessee, Lessor shall have the right to recover Lessor's damages from Lessee
except as released and waived in Paragraph 8.6.

  9.5 DAMAGE NEAR END OF TERM. If at any time during the last six (6) months of
the term 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, at Lessor's
option, terminate this Lease effective sixty,(60) days following the date of
occurrence of such damage by giving written notice to Lessee of Lessor's
election to do so within thirty (30) days after the date of occurrence of such
damage. Provided, however, if Lessee at that time has an exercisable option to
extend this Lease or to purchase the Premises, then Lessee may preserve this
Lease by, within twenty (20) days following the occurrence of the damage, or
before the expiration of the time provided in such option for its exercise,
whichever is earlier ("Exercise Period"), (i) exercising such option and (ii)
providing Lessor with any shortage in insurance proceeds (or adequate assurance
thereof) needed to make the repairs. If Lessee duly exercises such option during
said Exercise Period and provides Lessor with funds (or adequate assurance
thereof) to cover any shortage in insurance proceeds, Lessor shall, at Lessor's
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 said Exercise Period, then Lessor may at
Lessor's option terminate this Lease as of the expiration of said sixty (60) day
period following the occurrence of such damage by giving written notice to
Lessee of Lessor's election to do so within ten (10) days after the expiration
of the Exercise Period, notwithstanding any term or provision in the grant of
option to the contrary.

  9.6 ABATEMENT OF RENT; LESSEE'S REMEDIES.

     (a) In the event of damage described in Paragraph 9.2 (Partial
Damage--Insured), whether or not Lessor or Lessee repairs or restores the
Premises, the Base Rent, Real Property Taxes, insurance premiums, and other
charges, if any, payable by Lessee hereunder for the period during which such
damage, its repair or the restoration continues (not to exceed the period for
which rental value insurance is required under Paragraph 8.3(b)), shall be
abated in proportion to the degree to which Lessee's use of the Premises is
impaired. Except for abatement of Base Rent, Real Property Taxes, insurance
premiums, and other charges, if any, as aforesaid, all other obligations of
Lessee hereunder shall be performed by Lessee, and Lessee shall have no claim
against Lessor for any damage suffered by reason of any such repair or
restoration.

     (b) If Lessor shall be obligated to repair or restore the Premises under
the provisions of this Paragraph 9 and shall not commence, in a substantial  and
meaningful way, the repair or restoration of the Premises within ninety (90)
days after such obligation shall accrue, Lessee may, at any time prior to the
commencement of such repair or restoration, give written notice to Lessor and to
any Lenders of which Lessee has actual notice of Lessee's election  to terminate
this Lease on a date not less than sixty (60) days following the giving of such
notice. If Lessee gives such notice to Lessor and such Lenders and such repair
or restoration is not commenced within thirty (30) days after receipt of such
notice, this Lease shall terminate as of the date specified in  said notice. If
Lessor or a Lender commences the repair or restoration of the Premises within
thirty (30) days after receipt of such notice, this Lease shall continue in full
force and effect. "Commence" as used in this Paragraph shall mean either the
unconditional authorization of the preparation of the required plans, or the
beginning of the actual work on the Premises, whichever first occurs.

  9.7 HAZARDOUS SUBSTANCE CONDITIONS. If a Hazardous Substance Condition occurs,
?????? to the provisions of Paragraph 6 of the Addendum, Lessor may at 
Lessor's option either (i) investigate and remediate such Hazardous Substance 
Condition, if required, as soon as reasonably possible at Lessor's expense 
but subject to Lessee's indemnity obligations under Paragraph 6 of the 
Addendum, in which event this Lease shall continue in full force and effect, 
or (ii) if the estimated cost to investigate and remediate such condition 
exceeds twelve times the then monthly Base Rent or $100,000, whichever is 
greater, give written notice to Lessee within thirty (30) days after receipt 
by Lessor of knowledge of the occurrence of such Hazardous Substance 
Condition of Lessor's desire to terminate this Lease as of the date sixty 
(60) days following the giving of such notice. In the event Lessor elects to 
give such notice of Lessor's intention to terminate this Lease, Lessee shall 
have the right within ten (10) days after the receipt of such notice to give 
written notice to Lessor of Lessee's commitment to pay for the investigation 
and remediation of such Hazardous Substance Condition totally at Lessee's 
expense and without reimbursement from Lessor except to the extent of an 
amount equal to twelve (12) times the then monthly Base Rent or $100,000, 
whichever is greater. Lessee shall provide Lessor with the fund required of 
Lessee or satisfactory assurance thereof within thirty (30) days following 
Lessee's said commitment. In such event this Lease shall continue in full 
force and effect, and Lessor shall proceed to make such investigation and 
remediation as soon as reasonably possible and the required funds are 
available. If Lessee does not give such notice and provide the required funds 
or assurance thereof within the times specified above, this Lease shall 
terminate as of the date specified in Lessor's notice of termination. If a 
Hazardous Substance Condition occurs for which Lessee is not legally 
responsible, there shall be abatement of Lessee's obligations under this 
Lease to the same extent as provided in Paragraph 9.6(a) for a period of not 
to exceed twelve(12) months.

  9.8 TERMINATION-ADVANCE PAYMENTS. Upon termination of this Lease pursuant to
this 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 under the terms of this Lease.

  9.9 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 (a) PAYMENT OF TAXES. Lessee shall pay the Real Property Taxes, as
defined in Paragraph 10.2, applicable to the Premises during the term of this
Lease. Subject to Paragraph 10.1(b), all such payments shall be made at least
ten (10) days prior to the delinquency date of the applicable installment.
Lessee shall promptly furnish Lessor with satisfactory evidence that such taxes
have been paid. If any such taxes to be paid by Lessee shall cover any period of
time prior to or after the expiration or earlier termination of the term hereof,
Lessee's share of such taxes shall be equitably prorated to cover only the
period of time within the tax fiscal year this Lease is in effect, and Lessor
shall reimburse Lessee for any overpayment after such proration. If Lessee shall
fail to pay any Real Property Taxes required by this Lease to be paid by Lessee,
Lessor shall have the right to pay the same, and Lessee shall reimburse Lessor
therefor upon demand.

      (b) ADVANCE PAYMENT. In order to insure payment when due and before
delinquency of any or all Real Property Taxes, Lessor reserves the right, at
Lessor's option, to estimate the current Real Property Taxes applicable to the
Premises, and to require such current year's Real Property Taxes to 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 that
equal monthly amount which, over the number of months remaining before the month
in which the applicable tax installment would become delinquent (and without
interest thereon), would provide a fund large enough to fully discharge before
delinquency the estimated installment of taxes to be paid. When the actual
amount of the applicable tax bill is known, the amount of such equal monthly
advance payment shall be adjusted as required to provide the fund needed to pay
the applicable taxes before delinquency. If the amounts paid to Lessor by Lessee
under the provisions of this Paragraph are insufficient to discharge the
obligations of Lessee to pay such Real Property Taxes as the same become due,
Lessee shall pay to Lessor, upon Lessor's demand, such additional sums as are
necessary to pay such obligations. All moneys paid to Lessor under this
Paragraph may be intermingled with other moneys of Lessor and shall not bear
interest. In the event of a Breach by Lessee in the performance of the
obligations of Lessee under this Lease, then any balance of funds paid to Lessor
under the provisions of this Paragraph may, subject to proration as provided in
Paragraph 10.1(a), at the option of Lessor, be treated as an additional Security
Deposit under Paragraph 5.

  10.2 DEFINITION OF "REAL PROPERTY TAXES." As used herein, the term "REAL
PROPERTY TAXES" shall include any form of real estate tax or assessment,
general, special, ordinary or extraordinary, and any license fee, commercial
rental tax, improvement bond or bonds, levy or tax (other than inheritance,
personal income or estate taxes) imposed upon the Premises by any authority
having the direct or indirect power to tax, including any city, state or federal
government, or any school, agricultural, sanitary, fire, street, drainage or
other improvement district thereof, levied against any legal or equitable
interest of Lessor in the Premises or in the real property of which the Premises
are a part, Lessor's right to rent or other income therefrom, and/or Lessor's
business of leasing the Premises. The term "REAL PROPERTY TAXES" shall also
include any tax, fee, levy, assessment or charge, or any increase therein,
imposed by reason of events occurring, or changes in applicable law taking
effect, during the term of this Lease, including but not limited to a change in
the ownership of the Premises or in the improvements thereon, the execution of
this Lease, or any modification, amendment or transfer thereof, and whether or
not contemplated by the Parties.

  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 determined by Lessor from the respective valuations

NET                                 PAGE 5
<PAGE>


assigned in the assessor's work sheets or such other information as may be
reasonably available. Lessor's reasonable determination thereof, in good faith,
shall be conclusive.

   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 contained in the Premises or elsewhere. When possible, Lessee shall
cause its Trade Fixtures, furnishings, equipment and all other personal property
to be assessed and billed separately from the real property of Lessor. If any of
Lessees said personal property shall be assessed with Lessor's real property,
Lessee shall pay Lessor the taxes attributable to Lessee within ten (10) days
after receipt of a written statement setting forth the taxes applicable to
Lessee's property or, at Lessor's option, as provided in Paragraph 10.1(b).

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 with other premises.

12. ASSIGNMENT AND SUBLETTING.

   12.1 LESSOR'S CONSENT REQUIRED.

      (a) Lessee shall not voluntarily or by operation of law assign, transfer,
mortgage or otherwise transfer or encumber (collectively, "ASSIGNMENT") or
sublet all or any part of Lessee's interest in this Lease or in the Premises
without Lessor's prior written consent given under and subject to the terms of
Paragraph 36.

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

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

      (d) An assignment or subletting of Lessee's interest in this Lease
without Lessor's specific prior written 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 unconsented to assignment or subletting as a noncurable Breach, Lessor
shall have the right to either: (i) terminate this Lease, or (ii) upon thirty
(30) days written notice ("Lessor's Notice"), increase the monthly Base Rent to
fair market rental value or one hundred ten percent (110%) of the Base Rent then
in effect, whichever is greater. Pending determination of the new fair market
rental value, if disputed by Lessee, Lessee shall pay the amount set forth in
Lessor's Notice, with any overpayment credited against the next installment(s)
of Base Rent coming due, and any underpayment for the period retroactively to
the effective date of the adjustment being due and payable immediately upon the
determination thereof. Further, in the event of such Breach and market value
adjustment, (i) the purchase price of any option to purchase the Premises held
by Lessee shall be subject to similar adjustment to the then fair market value
(without the Lease being considered an encumbrance or any deduction for
depreciation or obsolescence, and considering the Premises at its highest and
best use and in good condition), or one hundred ten percent (110%) of the price
previously in effect, whichever is greater, (ii) any index-oriented rental or
price adjustment formulas contained in this Lease shall be adjusted to require
that the base index be determined with reference to the index applicable to the
time of such adjustment, and (iii) any fixed rental adjustments scheduled during
the remainder of the Lease term shall be increased in the same ratio as the new
market rental bears to the Base Rent in effect immediately prior to the market
value adjustment.

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

   12.2 TERMS AND CONDITIONS APPLICABLE TO ASSIGNMENT AND SUBLETTING.

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

      (b) Lessor may accept any 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 any rent or performance shall constitute a waiver or
estoppel of Lessor's right to exercise its remedies for the Default or Breach by
Lessee of any of the terms, covenants or conditions of this Lease.

      (c) The consent of Lessor to any assignment or subletting shall not
constitute a consent to any subsequent assignment or subletting by Lessee or to
any subsequent or successive assignment or subletting by the sublessee. However,
Lessor may consent to subsequent sublettings and assignments of the sublease or
any amendments or modifications thereto without notifying Lessee or anyone else
liable on the Lease or sublease and without obtaining their consent, and such
action shall not relieve such persons from liability under this Lease or
sublease.

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

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

      (f) Any assignee of, or sublessee under, this Lease shall, by reason of
accepting such assignment or entering into such sublease, be deemed, for the
benefit of Lessor, 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.

     (g) The occurrence of a transaction described in Paragraph 12.1(c) shall
give Lessor the right (but not the obligation) to require that the Security
Deposit be increased to an amount equal to six (6) times the then monthly Base
Rent, and Lessor may make the actual receipt by Lessor of the amount required to
establish such Security Deposit a condition to Lessor's consent to such
transaction.

    (h) Lessor, as a condition to giving its consent to any assignment or
subletting, may require that the amount and adjustment structure of the rent
payable under this Lease be adjusted to what is then the Market Value and/or
adjustment structure for property similar to the Premises as then constituted.

  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 rentals and income arising from any sublease of all or a portion of the
Premises heretofore or hereafter made by Lessee, and Lessor may collect such
rent and income and apply same toward Lessee's obligations under this Lease;
provided, however, that until a Breach (as defined in Paragraph 13.1) shall
occur in the performance of Lessee's obligations under this Lease, Lessee may,
except as otherwise provided in this Lease, receive, collect and enjoy the rents
accruing under such sublease. Lessor shall not, by reason of this or any other
assignment of such sublease to Lessor, nor by reason of the collection of the
rents from a sublessee, be deemed liable to the sublessee for any failure of
Lessee to perform and comply with any of Lessee's obligations to such sublessee
under such sublease. Lessee hereby irrevocably authorizes and directs any such
sublessee, upon receipt of a written notice from Lessor stating that a Breach
exists in the performance of Lessee's obligations under this Lease, to pay to
Lessor the rents and other charges due and to become due under the sublease.
Sublessee shall rely upon any such statement and request from Lessor and shall
pay such rents and other charges to Lessor without any obligation or right to
inquire as to whether such Breach exists and notwithstanding any notice from or
claim from Lessee to the contrary. Lessee shall have no right or claim against
said sublessee, or, until the Breach has been cured, against Lessor, for any
such rents and other charges so paid by said sublessee to Lessor.

    (b) In the event of a Breach by Lessee in the performance of its obligations
under this Lease, Lessor, at its option and without any obligation to do so, may
require any 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 other prior Defaults or Breaches of
such sublessor under such sublease.

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

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

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


3. DEFAULT; BREACH; REMEDIES.

  13.1 DEFAULT; BREACH. Lessor and Lessee agree that if an attorney is consulted
by Lessor in connection with a Lessee Default or Breach (as hereinafter
defined), $350.00 is a reasonable minimum sum per such occurrence for legal
services and costs in the preparation and service of a notice of Default, and
that Lessor may include the cost of such services and costs in said notice as
rent due and payable to cure said Default. A "Default" is defined as failure by
the Lessee to observe, comply with or perform any of the terms, covenants,
conditions or rules applicable to Lessee under this Lease. A "Breach"

NET                                 PAGE 6
<PAGE>


is defined as the occurrence of any one or more of the following Defaults, and,
where a grace period for cure after notice is specified herein, the failure by
Lessee to cure such Default prior to the expiration of the applicable grace
period, shall entitle Lessor to pursue the remedies set forth in Paragraphs 13.2
and/or 13.3:

    (a) The vacating of the premises without the intention to reoccupy same, or
the abandonment of the Premises.

    (b) Except as expressly otherwise provided in this Lease, the failure by
Lessee to make any payment of Base Rent or any other monetary payment required
to be made by Lessee hereunder, whether to Lessor or to a third party, as and
when due, the failure by Lessee to provide Lessor with reasonable evidence of
insurance or surety bond required under this Lease, or the failure of Lessee to
fulfill any obligation under this Lease which endangers or threatens life or
property, where such failure continues for a period of three (3) days following
written notice thereof by or on behalf of Lessor to Lessee.

    (c) Except as expressly otherwise provided in this Lease, the failure by
Lessee to provide Lessor with reasonable written evidence (in duly executed
original form, if applicable) of (i) compliance with Applicable Law per
Paragraph 6.3, (ii) the inspection, maintenance and service contracts required
under Paragraph 7.1(b), (iii) the rescission of an unauthorized assignment or
subletting per Paragraph 12.1(b), (iv) a Tenancy Statement Per Paragraphs 16 or
37, (v) the subordination or non-subordination of this Lease per Paragraph 30,
(vi) the guaranty of the performance of Lessee's obligations under this Lease if
required under Paragraphs 1.11 and 37, (vii) The execution of any document
requested under Paragraph 42 (easements), or (viii) any other documentation or
information which Lessor may reasonably require of Lessee under the terms of
this Lease, where any such failure continues for a period of ten (10) days
following written notice by or on behalf of Lessor 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 that are to be
observed, complied with or performed by Lessee, other than those described in
subparagraphs (a), (b) or (c), above, where such Default continues for a period
of thirty (30) days after written notice thereof by or on behalf of Lessor to
Lessee; 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 of this Lease by Lessee 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 by 
Lessee of any general arrangement or assignment for the benefit of creditors: 
(II) Lessee's becoming a "debtor" as defined in 11 U.S.C. Section 101 or any 
successor statute thereto (unless, in the case of a petition filed against 
Lessee, the same is dismissed within sixty (60) days); (iii) the appointment 
of a trustee or receiver to take possession of substantially all of Lessee's 
assets located at the Premises or of Lessee's interest in this Lease, where 
possession is not restored to Lessee within thirty (30) days; or (iv) the 
attachment, execution or other judicial seizure of substantially all of 
Lessee's assets located at the Premises or of Lessee's interest in this 
Lease, where such seizure is not discharged within thirty (30) days; 
provided, however, in the event that any provision of this subparagraph (e) 
is contrary to any applicable law, such provision shall be of no force or 
effect, and not affect the validity of the remaining provisions.

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

    (g) If the performance of Lessee's obligations under this Lease is
guaranteed: (i) the death of a guarantor, (ii) the termination of a guarantor's
liability with respect to this Lease other than in accordance with the terms of
such guaranty, (iii) a guarantor becoming insolvent or the subject of a
bankruptcy filing, (iv) a guarantor's refusal to honor the guaranty, or (v) a
guarantor's breach of its guaranty obligation on an anticipatory breach basis,
and Lessee's failure, within sixty (60) days following written notice by or on
behalf of Lessor to Lessee of any such event, to provide Lessor with written
alternative assurance or security, which, when coupled with the then existing
resources of Lessee, equals or exceeds the combined financial resources of
Lessee and the guarantors that existed at the time of execution of this Lease.

  13.2 REMEDIES. If lessee fails to perform any affirmative duty or 
obligation of Lessee under this Lease, within ten (10) days after written 
notice to Lessee (or in case of an emergency, without notice), Lessor may at 
its option (but without obligation to do so), 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 to Lessor upon invoice therefor. If any check given 
to Lessor by Lessee shall not be honored by the bank upon which it is drawn, 
Lessor, at its option, may require all future payments to be made under this 
Lease by Lessee to be made only by cashier's check In the event of a Breach 
of this Lease by Lessee, as defined in Paragraph 13.1, 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, Lessor may:

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

    (b) Continue the Lease and Lessee's right to possession in effect (in
California under California Civil Code Section 1951.4) after Lessee's Breach and
abandonment and recover the rent as it becomes due, provided Lessee has the
right to sublet or assign, subject only to reasonable limitations. See
Paragraphs 12 and 36 for the limitations on assignment and subletting which
limitations Lessee and Lessor agree are reasonable. Acts of maintenance or
preservation, efforts to relet the Premises, or the appointment of a receiver to
protect the Lessor's interest under the Lease, shall not constitute a
termination of the Lessee's right to possession.

    (c) Pursue any other remedy now or hereafter available to Lessor under the
laws or Judicial decisions of the state wherein the Premises are located.

    (d) 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 IN EVENT OF BREACH. Any agreement by Lessor for
free or abated rent or other charges applicable to the Premises, 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 to be performed or observed by
Lessee during the term hereof as the same may be extended. Upon the occurrence
of a Breach of this Lease by Lessee, as defined in Paragraph 13.1, any such
inducement Provision shall automatically be deemed deleted from this Lease and
of no further force or effect, and any rent, other charge, bonus, inducement or
consideration theretofore abated, given or paid by Lessor under such an
Inducement Provision shall be immediately due and payable by Lessee to Lessor,
and recoverable by Lessor as additional rent due under this Lease,
notwithstanding any subsequent cure of said Breach by Lessee. The acceptance by
Lessor of rent or the cure of the Breach which initiated the operation of this
Paragraph shall not be deemed a waiver by Lessor of the provisions of this
Paragraph unless specifically so stated in writing by Lessor at the time of such
acceptance.

  13.4 LATE CHARGES. Lessee hereby acknowledges that late payment by Lessee to
Lessor of rent and other sums due hereunder 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 the
terms of any ground lease, mortgage or trust deed covering the Premises.
Accordingly, if any installment of rent or any other sum due from Lessee shall
not be received by Lessor or Lessor's designee within five (5) days after such
amount shall be due, then, without any requirement for notice to Lessee, Lessee
shall pay to Lessor a late charge equal to six percent (6%) 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 late payment by
Lessee. 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 Lessor from exercising 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 Paragraph 4.1 or any other provision of this Lease to the
contrary, Base Rent shall, at Lessor's option, become due and payable quarterly
in advance.

  13.5 BREACH BY LESSOR. 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 13.5, a reasonable
time shall in no event be less than thirty (30) days after receipt by Lessor,
and by the holders of any ground lease, mortgage or deed of trust covering the
Premises 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 it the nature of Lessor's obligation
is such that more than thirty (30) days after such notice are reasonably
required for its performance, then Lessor shall not be in breach of this Lease
if performance is commenced within such thirty (30) day period and thereafter
diligently pursued to completion.

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
(all of which are herein called "CONDEMNATION"), this Lease shall terminate as
to the part so taken as of the date the condemning authority takes

NET                                 PAGE 7
<PAGE>

title or possession, whichever first occurs. If more than ten percent (10%) of
the floor area of the Premises, or more than twenty-five percent (25%) of the
land area not occupied by any building, is taken by condemnation, Lessee may, at
Lessees option, to be exercised in writing within ten (10) days after Lessor
shall have given Lessee written notice of such taking (or in the absence of such
notice, within ten (10) days after the condemning authority shall have taken
possession) terminate this Lease as of the date the condemning authority takes
such possession. If Lessee does not terminate this Lease in accordance with the
foregoing, this Lease shall remain in full force and effect as to the portion of
the Premises remaining, except that the Base Rent shall be reduced in the same
proportion as the rentable floor area of the Premises taken bears to the total
rentable floor area of the building located on the Premises. No reduction of
Base Rent shall occur if the only portion of the Premises taken is land on which
there is no building. Any award for the taking of all or any part of the
Premises under the power of eminent domain or any payment made under threat of
the exercise of such power shall be the property of Lessor, whether such award
shall be made as compensation for diminution in value of the leasehold or for
the taking of the fee, or as severance damages; provided, however, that Lessee
shall be entitled to any compensation separately awarded to Lessee for Lessee's
relocation expenses and/or loss of Lessee's Trade Fixtures. In the event that
this Lease is not terminated by reason of such condemnation, Lessor shall to the
extent of its net severance damages received, over and above the legal and other
expenses incurred by Lessor in the condemnation matter, repair any damage to the
Premises caused by such condemnation, except to the extent that Lessee has been
reimbursed therefor by the condemning authority. Lessee shall be responsible for
the payment of any amount in excess of such net severance damages required to
complete such repair.

15. BROKER'S FEE.

  15.5 Lessee and Lessor each represent and warrant to the other that it has had
no dealings with any person, firm, broker or finder in connection with the
negotiation of this Lease and/or the consummation of the transaction
contemplated hereby, and that no broker or other person, firm or entity is
entitled to any commission or finder's fee in connection with said transaction.
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 broker, finder or other similar party by reason of any
dealings or actions of the indemnifying Party, including any costs, expenses,
attorneys' fees reasonably incurred with respect thereto.


16. TENANCY STATEMENT.

  16.1 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 "Tenancy Statement" 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.

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

17. LESSOR'S LIABILITY. The term "LESSOR" as used herein shall mean the owner or
owners at the time in question of the fee title to the Premises, or, if this is
a sublease, of the Lessee's interest in the prior Lease. In the event of a
transfer of Lessor's title or interest in the Premises or in this Lease, Lessor
shall deliver to the transferee or assignee (in cash or by credit) any unused
Security Deposit held by Lessor at the time of such transfer or assignment.
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.

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. INTEREST ON PAST-DUE OBLIGATIONS. Any monetary payment due Lessor hereunder,
other than late charges, not received by Lessor within thirty (30) days
following the date on which it was due, shall bear interest from the
thirty-first (31st) day after it was due at the rate of 12% per annum, but not
exceeding the maximum rate allowed by law, in addition to the late charge
provided for in Paragraph 13.4.

20. 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.

21. RENT DEFINED. All monetary obligations of Lessee to Lessor under the terms
of this Lease are deemed to be rent.

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 or contemporaneous agreement or understanding shall be effective.
Lessor and Lessee each represents and warrants to the Brokers that it has made,
and is relying solely upon, its own investigation as to the nature, quality,
character and financial responsibility of the other Party to this Lease and as
to the nature, quality and character of the Premises. Brokers have no
responsibility with respect thereto or with respect to any default or breach
hereof by either Party.

23. NOTICES.

  23.1 All notices required or permitted by this Lease shall be in writing and
may be delivered in person (by hand or by messenger or courier service) 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 notice purposes. Either Party may by
written notice to the other specify a different address for notice purposes,
except that upon Lessee's taking possession of the Premises, the Premises shall
constitute Lessee's address for the purpose of mailing or delivering notices to
Lessee. A copy of all notices required or permitted to be given to Lessor
hereunder shall be concurrently transmitted to such party or parties at such
addresses as Lessor may from time to time hereafter designate by written notice
to Lessee.

  23.2 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 guarantees next day
delivery shall be deemed given twenty-four (24) hours after delivery of the same
to the United States Postal Service or courier. If any notice is transmitted by
facsimile transmission or similar means, the same shall be deemed served or
delivered upon telephone confirmation of receipt of the transmission thereof,
provided A copy is also delivered via delivery or mail. IF notice is received on
A Sunday or legal holiday, it shall be deemed received on the next business day.

24. WAIVERS. No waiver by Lessor of the Default or Breach of any term, covenant
or condition hereof by Lessee, shall be deemed a waiver of any other term,
covenant or condition hereof, or of any subsequent Default or Breach by Lessee
of the same or of any other term, covenant or condition hereof. Lessor's consent
to, or approval of, any act shall not be deemed to render unnecessary the
obtaining of Lessor's consent to, or approval of, any subsequent or similar act
by Lessee, or be construed as the basis of an estoppel to enforce the provision
or provisions of this Lease requiring such consent. Regardless of Lessor's
knowledge of a Default or Breach at the time of accepting rent, the acceptance
of rent by Lessor shall not be a waiver of any preceding Default or Breach by
Lessee of any provision hereof, other than the failure of Lessee to pay the
particular rent so accepted. Any payment given Lessor by Lessee may be accepted
by Lessor on account of moneys or damages due Lessor, notwithstanding any
qualifying statements or conditions made by Lessee in connection therewith,
which such statements and/or conditions shall be of no force or effect
whatsoever unless specifically agreed to in writing by Lessor at or before the
time of deposit of such payment.

25. RECORDING. Either Lessor 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 requesting recordation shall be
responsible for payment of any fees or taxes applicable thereto.

26. NO RIGHT TO HOLDOVER. Lessee has no right to retain possession of the
Premises or any part thereof beyond the expiration or earlier termination of
this Lease.

NET                                 PAGE 8
<PAGE>


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

28. COVENANTS AND CONDITIONS. All provisions of This Lease to be observed or
performed by Lessee are both covenants and conditions.

29. BINDING EFFECT; CHOICE OF LAW. This Lease shall be binding upon the parties,
their personal representatives, successors and assigns and be governed by the
laws of the state in which the Premises are located. Any litigation between the
Parties hereto concerning this Lease shall be initiated in the county in which
the Premises are located.

30. SUBORDINATION; ATTORNMENT; NON-DISTURBANCE.

  30.1 SUBORDINATION. This Lease and any Option granted hereby shall be subject
and subordinate to any ground lease, mortgage, deed of trust, or other
hypothecation or security device (collectively, "SECURITY DEVICE"), now or
hereafter placed by Lessor upon the real property of which the Premises are a
part, to any and all advances made on the security thereof, and to all renewals,
modifications, consolidations, replacements and extensions thereof. Lessee
agrees that the Lenders holding any such Security Device shall have no duty,
liability or obligation to perform any of the obligations of Lessor under this
Lease, but that in the event of Lessor's default with respect to any such
obligation, Lessee will give any Lender whose name and address have been
furnished Lessee in writing for such purpose notice of Lessor's default and
allow such Lender thirty (30) days following receipt of such notice for the cure
of said default before invoking any remedies Lessee may have by reason thereof.
If any Lender shall elect to have this Lease and/or any Option granted hereby
superior to the lien of its Security Device and shall give written notice
thereof to Lessee, this Lease and such Options shall be deemed prior to such
Security Device, notwithstanding the relative dates of the documentation or
recordation thereof.

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 prior lessor, or (iii) be bound by prepayment of
more than one (1) month's rent.

  30.3 NON-DISTURBANCE. With respect to Security Devices entered into by Lessor
after the execution of this Lease, Lessee's subordination of this Lease shall be
subject to receiving assurance (a "NON-DISTURBANCE AGREEMENT") from the Lender
that Lessee's possession 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.

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

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

32. LESSOR'S ACCESS; SHOWING PREMISES; REPAIRS. Lessor and Lessor's agents shall
have the right to enter the Premises at any time, in the case of an emergency,
and otherwise at reasonable times for the purpose of showing the same to
prospective purchasers, lenders, or lessees, and making such alterations;
repairs, improvements or additions to the Premises or to the building of which
they are a part, as Lessor may reasonably deem necessary. Lessor may at any time
place on or about the Premises or building any ordinary "For Sale" signs and
Lessor may at any time during the last one hundred twenty (120) days of the term
hereof place on or about the Premises any ordinary "For Lease" signs. All such
activities of Lessor shall be without abatement of rent or liability to Lessee.

33. AUCTIONS. Lessee shall not conduct, nor permit to be conducted, either
voluntarily or involuntarily, any auction upon the Premises without first having
obtained Lessor's prior written consent. Notwithstanding anything to the
contrary in this Lease, Lessor shall not be obligated to exercise any standard
of reasonableness in determining whether to grant such consent.

34. SIGNS. Lessee shall not place any sign upon the Premises, except that Lessee
may, with Lessor's prior written consent, install (but not on the roof) such
signs as are reasonably required to advertise Lessee's own business. The
installation of any sign on the Premises by or for Lessee shall be subject to
the provisions of Paragraph 7 (Maintenance, Repairs, Utility Installations,
Trade Fixtures and Alterations). Unless otherwise expressly agreed herein,
Lessor reserves all rights to the use of the roof and the right to install, and
all revenues from the installation of, such advertising signs on the Premises,
including the root, as do not unreasonably interfere with the conduct of
Lessee's business.

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

36. CONSENTS.

     (a) Except for Paragraph 33 hereof (Auctions) or as otherwise provided
herein, wherever in this Lease the consent of a Party is required to an act by
or for the other Party, such consent shall not be unreasonably withheld or
delayed. Lessor's actual reasonable costs and expenses (including but not
limited to architects', attorneys', engineers' or other consultants' fees)
incurred in the consideration of, or response to, a request by Lessee for any
Lessor consent pertaining to this Lease or the Premises, including but not
limited to consents to an assignment, a subletting or the presence or use of a
Hazardous Substance, practice or storage tank, shall be paid by Lessee to Lessor
upon receipt of an invoice and supporting documentation therefor. Subject to
Paragraph 12.2(e) (applicable to assignment or subletting), Lessor may, as a
condition to considering any such request by Lessee, require that Lessee deposit
with Lessor an amount of money (in addition to the Security Deposit held under
Paragraph 5) reasonably calculated by Lessor to represent the cost Lessor will
incur in considering and responding to Lessee's request. Except as otherwise
provided, any unused portion of said deposit shall be refunded to Lessee without
interest. Lessor's consent to any act, assignment of this Lease or subletting of
the Premises by Lessee shall not constitute an acknowledgment that no Default or
Breach by Lessee of this Lease exists, nor shall such consent be deemed a waiver
of any then existing Default or Breach, except as may be otherwise specifically
stated in writing by Lessor at the time of such consent.

     (b) All conditions to Lessor's consent authorized by this Lease are
acknowledged by Lessee as being reasonable. The failure to specify herein any
particular condition to Lessor's consent shall not preclude the imposition by
Lessor at the time of consent of such further or other conditions as are then
reasonable with reference to the particular matter for which consent is being
given.

38. QUIET POSSESSION. Upon payment by Lessee of the rent for the Premises and
the observance and performance of all of the covenants, conditions and
provisions on Lessee's part to be observed and performed under this Lease,

restrictions do not unreasonably interfere with the use of the Premises by
Lessee. Lessee agrees to sign any documents reasonably requested by Lessor to
effectuate any such easement rights, dedication, map or restrictions

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

have the same force and effect as if set forth at length in the body of the

terms and provisions of the Lease to which this Addendum is attached, the terms
and provisions of this Addendum shall control.

    1.   LESSEE PRIOR OCCUPANT/ACCEPTANCE OF PREMISES "AS IS". Notwithstanding
anything contained in the Lease to the contrary, the provisions of this
Paragraph 1 shall control and prevail.

         1.1  LESSEE PRIOR OCCUPANT. Lessor and Lessee acknowledge and agree
that immediately prior to the Commencement Date of this Lease, Lessee was the
occupant of the Premises pursuant to that certain Lease ("Prior Lease"), dated

and Burke Rubber Company, Inc. ("Original Lessee"), which Prior Lease was for a
twenty-five (25) year term expiring immediately prior to the Commencement Date

                                       foot per month, adjusted by the C.P.I.
                                       Annual Multiplier (as defined below)

         4 through Expiration Date     Base Rent at the rate paid during the
                                       immediately prior Lease Year, adjusted
                                       by the C.P.I. Annual Multiplier (as
                                       defined below)

For purposes of calculating the amount of Base Rent payable during the Term
(including without limitation payable during any Extended Term as provided under
Paragraph 5 below), the square footage of the Premises shall be 82,000 square
feet. Base Rent shall be paid in advance on or before the first day of each
calendar month during the Term. Base Rent shall be prorated for any partial
month at the beginning or end of the Term. Base Rent during the Extended Terms
shall be as stated in Paragraph 5.2 below.

         4.2  LEASE YEAR. As used herein, "Lease Year" shall mean any twelve
(12) month period from January 1 to December 31 in each calendar year during the
Term. In the case of the beginning of the Original Term, the provisions "Lease
Year" shall mean the period from the Commencement Date to December 31, 1997; in
the case of the end of the Term, the provision Lease Year shall mean the period
from the last January 1 to occur during the Term to the Expiration Date.

         4.3  FAIR MARKET RENT. (i) If Lessor and Lessee cannot agree on the
Fair Market Rent within thirty (30) days prior to the commencement of the Lease
Year for which Fair Market Rent applies, each party shall, by notice to the
other, appoint a disinterested and licensed M.A.I. Real Estate Appraiser to
determine the Fair Market Rent. If any party should fail to appoint an
appraiser, the appraiser selected by the other party shall determine the Fair
Market Rent. In determining the Fair Market Rent, each appraiser shall give
appropriate consideration to, among other things, generally applicable terms and
conditions of tenancies for property comparable to the Premises in the general
vicinity of the Premises.

              (ii) If the two appraisers selected pursuant to Paragraph 4.3(i)
above cannot agree upon the Fair Market Rent within forty-five (45) days, they
shall immediately give written notice of such inability ("Notice of
Disagreement") to both Lessor and Lessee setting forth the Fair Market Rent
determinations of each of the appraisers. If the determinations of each of the
two appraisers differ by less than ten percent (10%) of the lower determination,
the Fair Market Rent shall be fixed at an amount equal to the average of the two
determinations.

              (iii) If the determinations of each of the two appraisers
selected pursuant to Paragraph 4.3(i) above, differ by ten percent (10%) or more
of the lower determination, then within thirty (30) days after the giving of the
Notice of Disagreement, the two appraisers shall appoint a third disinterested
and licensed M.A.I. Real Estate Appraiser. If the parties cannot then agree on
the Fair Market Rent, the third appraiser shall determine the Fair Market Rent,
and in so doing, shall give appropriate consideration to those items described
in Paragraph 4.3(i). The third appraiser shall not select a Fair Market Rent
either (a) higher than the higher of the two appraisals made pursuant to
Paragraph 4.3(i); or (b) lower than the lower of the two appraisals made
pursuant to Paragraph 4.3(i) above. If the first two appraisers cannot agree on
the selection of a third appraiser within such thirty (30) days, or if the first
two appraisers fail to provide a Notice of Disagreement (as stated above in
Paragraph 4.3(ii)), then the Fair Market Rent shall be determined by arbitration
in accordance with the Commercial Arbitration Rules of the American Arbitration
Association.


                                         -2-

<PAGE>

              (iv) During the time before the determination of the Fair Market
Rent, as specified above, Lessee shall continue to pay Base Rent at the same
rate as paid during the immediately preceding Lease Year; provided, however,
that, once the Fair Market Rent is determined, the Base Rent owed by Lessee at
the Fair Market Rent shall be effective retroactively as of the first day of
such Lease Year. If, after the Base Rent is adjusted and applied retroactively
as of the first day of such Lease Year, it is determined that additional rent is
due Lessor, the amount of any such additional rent shall be paid by Lessee
promptly after determination of the Fair Market Rent for such Lease Year (but
not later than the date of the next monthly installment of Base Rent, unless the
next installment falls due within five (5) days after determination of Fair
Market Rent, in which case not later than the date of the second next monthly
installment of Base Rent).

              (v)  Each of the parties shall pay the fees of the appraiser that
it selects pursuant to Paragraph 4.3(i) above, and shall equally share the cost
of the third appraiser, if necessary, and shall equally share the cost of
arbitration (excluding attorneys' fees), if necessary.

         4.4  C.P.I. ANNUAL MULTIPLIER. The "C.P.I. Annual Multiplier" shall be
the fraction, the numerator of which shall be the C.P.I. (defined below) for
January of the Lease Year then in effect, and the denominator of which shall be
the C.P.I. for January of the immediately preceding Lease Year. "C.P.I." shall
mean and refer to the Consumer Price Index published as the "CPI-U" index by the
Bureau of Labor Statistics of the Department of Labor, U.S. Cities Average, All
Items (1982-84=100); provided that if compilation of the C.P.I. is discontinued
or transferred to any other governmental department or bureau, then the index
most nearly the same as the C.P.I. shall be used. If Lessor is unable to
determine the C.P.I. by January 1 of any Lease Year, Lessee shall continue to
pay the Base Rent at the rate paid for the immediately prior Lease Year, and
once the C.P.I. for January 1 of such Lease Year is published, the new Base Rent
(as increased by the C.P.I. Annual Multiplier) shall be effective retroactively
as of the first day of such Lease Year and the aggregate amount of any
additional Base Rent shall be paid by Lessee promptly after written notice
thereof from Lessor (but not later than the date of the next monthly installment
of Base Rent, unless the next installment falls due within five (5) days after
Lessor's notice, in which case not later than the date of the second next
monthly installment of Base Rent). No delay by Lessor in providing notice of any
such increase in Base Rent shall be deemed a waiver of Lessor's right to
increase the Base Rent as provided hereunder.

    5. OPTIONS TO EXTEND.

         5.1  OPTIONS TO EXTEND. Lessee shall have two (2) options to extend
the Original Term of the Lease (each, an "Option") for a period of five (5)
years each (each such additional term shall be referred to herein as an
"Extended Term") for the entire Premises, commencing immediately following the
end of the Original Term or the immediately preceding Extended Term as the case
may be. The Lease during any Extended Term shall be on the same terms and
conditions as during the Original Term, except that the Base Rent shall be
determined as set forth in Paragraph 5.2 below. In the event Lessee desires to
exercise any option to extend granted in this Paragraph 5.1, Lessee shall give
Lessor written notice ("Notice to Extend") not less than three hundred sixty
(360) days prior to the expiration of the Original Term or the immediately
preceding Extended Term, as the case may be. If Lessee fails to give Lessor any
such notice, then such option to extend and all future options to extend granted
in this Paragraph 5.1 shall be null and void.

         5.2  BASE RENT DURING EXTENDED TERMS. The Base Rent for the first
Lease Year in each Extended Term shall be the higher of: Fair Market Rent (as
determined in Paragraph 4.3 above); or the Base Rent at the rate paid
immediately preceding such Extended Term, adjusted by the C.P.I. Annual
Multiplier (as defined in Paragraph 4.4 above). The Base Rent for each
subsequent Lease Year in each Extended Term shall be the Base Rent at the rate
paid during the immediately prior Lease Year, adjusted by the C.P.I. Annual
Multiplier.

    6.   HAZARDOUS SUBSTANCES.

         6.1  LESSEE'S OBLIGATIONS FOR HAZARDOUS SUBSTANCES. Lessee shall, at
its sole cost and expense, take all actions as may be required to cause the
Premises including, but not limited to, the real property described in Exhibit
"A" attached hereto and all improvements located thereon, to be in compliance
with the applicable requirements under any federal, state and/or local law, any
judicial order and/or any governmental entity, relating to any Hazardous
Substances released, arising or discovered prior to, at, or after the
Commencement Date and during the Term.

         6.2  INDEMNIFICATION. Lessee hereby agrees to fully indemnify,
protect, defend and hold harmless Lessor from any costs, damages, claims,
liability or loss of any kind or nature that arise during or after the Term of
this Lease directly or indirectly from or in connection with the presence,
suspected presence, release or suspected release, removal or remediation of
Hazardous Substances in, on, under or about the Premises, or any part thereof,
whether or not such injury or damage has been caused in whole or in part by the
act, negligence, fault or omission of Tenant, its agents, servants, contractors,
employees, representatives, licensees or invitees. Lessee's obligations
hereunder shall apply to all Hazardous Substances, irrespective of when they
arose or were discovered and therefore will include any Hazardous Substances
that existed prior to, at, or after the Commencement Date and during the Term.

         6.3  REMEDIAL WORK. In the event any investigation or monitoring of
site conditions or any clean-up, containment, restoration, removal or other
remedial work (collectively, "Remedial Work") is required under any applicable
federal, state or local law, by any judicial order, or by any governmental
entity, Lessee shall perform or cause to be performed the Remedial Work in
compliance with such law or order. All Remedial Work shall be performed by one
or more contractors, selected by Lessee and approved in advance in writing by
Lessor, and under the supervision of a consulting engineer selected by Lessee
and approved in advance in writing by Lessor. All costs and expenses of such
Remedial Work shall be paid by Lessee, including without limitation the charges
of such contractor(s), the consulting engineer and Lessor's reasonable
attorneys' fees and costs incurred in connection with monitoring or review of
such Remedial Work.

         6.4  ARBITRATION. In the event that Lessor and Lessee are unable to
resolve any dispute concerning Hazardous Substances, or the provisions of this
Paragraph 6 or Paragraphs 6.2 or 9.7 of the Lease, then either party may request
that resolution of the dispute be determined pursuant to binding arbitration
under the Commercial Arbitration Rules of the American Arbitration Association.
In the event that the parties' dispute is resolved pursuant to arbitration, the
prevailing party shall be entitled to recover its reasonable attorneys' fees and
other costs and expenses incurred in connection with such arbitration.

         6.5  SURVIVAL. Each of the covenants and agreements of Lessee set
forth in this Paragraph 6, and in Paragraph 6 of the Lease, shall survive the
expiration or earlier termination of this Lease.

    7.   WAIVER OF SUBROGATION. In the event that Lessor's insurance policies
with respect to the Premises permit a waiver of subrogation, Lessor hereby
waives any and all rights of recovery against Lessee for loss of or damages to
the Premises arising out of or incident to the perils required to be insured
against under Paragraph 8 of the Lease; provided however that such waiver of
subrogation shall be limited exclusively to insurance proceeds actually received
by Lessor for such damage or destruction. In the event Lessee's insurance
policies with respect to the Premises permit a waiver of subrogation, Lessee
hereby waives any and all rights of recovery against Lessor for loss of or
damage to any property of Lessee arising out of or incident to the perils
required to be insured against under Paragraph 8 of the Lease.

    8.   SEISMIC UPGRADE. No later than December 31,1998, Lessee shall, at
Lessee's sole cost and expense, perform or cause to be performed all repairs and
other actions as may be necessary or appropriate to cause the Premises to be in
compliance with all applicable laws,


                                         -4-

<PAGE>

ordinances, rules and regulations relating to earthquake or seismic safety to
the satisfaction of the appropriate governmental entities or as otherwise
required by Lessor.

    9.   LESSOR EXCULPATION. It is expressly understood and agreed that
notwithstanding anything to the contrary in the Lease, and notwithstanding any
applicable law to the contrary, the liability of Lessor hereunder (including any
successor landlord) and any recourse by Lessee against Lessor shall be limited
solely and exclusively to the interests of Lessor in and to the Premises, and
neither Lessor, nor any of its constituent members or partners, shall have any
personal liability therefor, and Lessee hereby expressly waives and releases
such personal liability on behalf of itself and all persons claiming by, through
or under Lessee.
