2. Premises.

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

     2.2 Condition. Lessor shall deliver the Premises to Lessee broom clean and
free of debris on the Commencement Date ("Start Date"), and, so long as the
required service contracts described in Paragraph 7.1(b) below are obtained by
Lessee and in effect within thirty days following the Start Date, warrants that
the existing electrical, plumbing, fire sprinkler, lighting, heating,
ventilating and air conditioning systems ("HVAC"), loading doors, sump pumps, if
any, and all other such elements in the Premises, other than those constructed
by Lessee, shall be in good operating condition on said date and that the
structural elements of the roof, roof membrane, bearing walls and foundation of
any buildings on the Premises (the "Building") shall be free of material
defects. If a non-compliance with said warranty exists as of the Start Date, or
if one of such systems or elements should malfunction or fall within the
appropriate warranty period, Lessor shall, as Lessor's sole obligation with
respect to such matter, except as otherwise provided in this Lease, promptly
after receipt of written notice from Lessee setting forth with specificity the
nature and extent of such


                                                            /s/ BAC

                                     REVISED                    FORM STN-7-4/01E








non-compliance, malfunction or failure, rectify same at Lessor's expense. The
warranty periods shall be as follows: (i) 6 months as to the HVAC systems, and
(ii) 90 days as to the remaining systems and other elements of the Building. If
Lessee does not give Lessor the required notice within the appropriate warranty
period, correction of any such non-compliance, malfunction or failure shall be
the obligation of Lessee at Lessee's sole cost and expense.

     2.3 Compliance. Lessor warrants that the improvements on the Premises
comply with the building codes, applicable laws, covenants or restrictions of
record, regulations, and ordinances ("Applicable Requirements") that were in
effect at the time that each improvement, or portion thereof, was constructed.
Said warranty does not apply to the use to which Lessee will put the Premises,
modifications which may be required by the Americans with Disabilities Act or
any similar laws as a result of Lessee's use (see Paragraph 50), or to any
Alterations or Utility Installations (as defined in Paragraph 7.3(a)) made or to
be made by Lessee. NOTE: Lessee is responsible for determining whether or not
the Applicable Requirements, and especially the zoning, are appropriate for
Lessee's intended use, and acknowledges that past uses of the Premises may no
longer be allowed. If the Premises do not comply with said warranty, Lessor
shall, except as otherwise provided, promptly after receipt of written notice
from Lessee setting forth with specificity the nature and extent of such
non-compliance, rectify the same at Lessor's expense. If Lessee does not give
Lessor written notice of a non-compliance with this warranty within 6 months
following the Start Date, correction of that non-compliance shall be the
obligation of Lessee at Lessee's sole cost and expense. If the Applicable
Requirements are hereafter changed so as to require during the term of this
Lease the construction of an addition to or an alteration of the Premises and/or
Building, the remediation of any Hazardous Substance, or the reinforcement or
other physical modification of the Unit, Premises and/or Building ("Capital
Expenditure"), Lessor and Lessee shall allocate the cost of such work as
follows:

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

          (b) If such Capital Expenditure is not the result of the specific and
unique use of the Premises by Lessee (such as, governmentally mandated seismic
modifications), then Lessor and Lessee shall allocate the obligation to pay for
such costs pursuant to the provisions of Paragraph 7.1(d); provided, however,
that if such Capital Expenditure is required during the last 2 years of this
Lease or if Lessor reasonably determines that it is not economically feasible to
pay its share thereof, Lessor shall have the option to terminate this Lease upon
90 days prior written notice to Lessee unless Lessee notifies Lessor, in
writing, within 10 days after receipt of Lessor's termination notice that Lessee
will pay for such Capital Expenditure. If Lessor does not elect to terminate,
and fails to tender its share of any such Capital Expenditure, Lessee may
advance such funds and deduct same, with interest, from Rent until Lessor's
share of such costs have been fully paid. If Lessee is unable to finance
Lessor's share, or if the balance of the Rent due and payable for the remainder
of this Lease is not sufficient to fully reimburse Lessee on an offset basis,
Lessee shall have the right to terminate this Lease upon 30 days written notice
to Lessor.

          (c) Notwithstanding the above, the provisions concerning Capital
Expenditures are intended to apply only to non-voluntary, unexpected, and new
Applicable Requirements. If the Capital Expenditures are instead triggered by
Lessee as a result of an actual or proposed change in use, change in intensity
of use, or modification to the Premises then, and in that event, Lessee shall
either: (i) immediately cease such changed use or intensity of use and/or take
such other steps as may be necessary to eliminate the requirement for such
Capital Expenditure, or (ii) complete such Capital Expenditure at its own
expense. Lessee shall not, however, have any right to terminate this Lease.

     2.4 Acknowledgements. Lessee acknowledges that: (a) it has been advised by
Lessor and/or Brokers to satisfy itself with respect to the condition of the
Premises (including but not limited to the electrical, HVAC and fire sprinkler
systems, security, environmental aspects, and compliance with Applicable
Requirements and the Americans with Disabilities Act), and their suitability for
Lessee's intended use, (b) Lessee has made such investigation as it deems
necessary with reference to such matters and assumes all responsibility therefor
as the same relate to its occupancy of the Premises, and (c) neither Lessor,
Lessor's agents, not Brokers have made any oral or written representations or
warranties with respect to said matters other than as set forth in this Lease.
In addition, Lessor acknowledges that: (i) Brokers have made no representations,
promises or warranties concerning Lessee's ability to honor the Lease or
suitability to occupy the Premises, and (ii) it is Lessor's sole responsibility
to investigate the financial capability and/or suitability of all proposed
tenants.

     2.5 Lessee as Prior Owner/Occupant. The warranties made by Lessor in
Paragraph 2 shall be of no force or effect if immediately prior to the Start
Date Lessee was the owner or occupant of the Premises. In such event, Lessee
shall be responsible for any necessary corrective work.

3.   Term.

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

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

     3.3 Delay in Possession. Lessor agrees to use its best commercially
reasonable efforts to deliver possession of the Premises to Lessee by the
Commencement Date. If, despite said efforts, Lessor is unable to deliver
possession by such date, Lessor shall not be subject to any liability therefor,
nor shall such failure affect the validity of this Lease. Lessee shall not,
however, be obligated to pay Rent or perform its other obligations until Lessor
delivers possession of the Premises and any period of rent abatement that Lessee
would otherwise have enjoyed shall run from the date of delivery of possession
and continue for a period equal to what Lessee would otherwise have enjoyed
under the terms hereof, but minus any days of delay caused by the acts or
omissions of Lessee. If possession is not delivered within 60 days after the
Commencement Date, Lessee may, at its option, by notice in writing within 10
days after the end of such 60 day period, cancel this Lease, in which event the
Parties shall be discharged from all obligations hereunder. If such written
notice is not received by Lessor within said 10 day period, Lessee's right to
cancel shall terminate. If possession of the Premises is not delivered within
120 days after the Commencement Date, this Lease shall terminate unless other
agreements are reached between Lessor and Lessee, in writing.

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

4.   Rent.

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

     4.2 Payment. Lessee shall cause payment of Rent to be received by Lessor in
lawful money of the United States on or before the day on which it is due,
without offset or deduction (except as specifically permitted in this Lease).
Rent for any period during the term hereof which is for less than one full
calendar month shall be prorated based upon the actual number of days of said
month. Payment of Rent shall be made to Lessor at its address stated herein or
to such other persons or place as Lessor may from time to time designate in
writing. Acceptance of a payment which is less than the amount then due shall
not be a waiver of Lessor's rights to the balance of such Rent, regardless of
Lessor's endorsement of any check so stating. In the event that any check,
draft, or other instrument of payment given by Lessee to Lessor is dishonored
for any reason, Lessee agrees to pay to Lessor the sum of $25 in addition to any
Late Charge and Lessor, at its option, may require all future payments to be
made by Lessee to be by cashier's check. Payments will be applied first to
accrued late charges and attorney's fees, second to accrued interest, then to
Base Rent and Operating Expense Increase, and any remaining amount to any other
outstanding charges or costs.

     4.3 Association Fees. In addition to the Base Rent, Lessee shall pay to
-Lessor each month an amount equal to any owner's association or condominium fees
levied or assessed against the Premises. Said monies shall be paid at the same
time and in the same manner as the Base Rent.

5. Security Deposit. Lessee shall deposit with Lessor upon execution hereof the
Security Deposit as security for Lessee's faithful performance of its
obligations under this Lease. If Lessee fails to pay Rent, or otherwise Defaults
under this Lease, Lessor may use, apply or retain all or any portion of said
Security Deposit for the payment of any amount due Lessor or to reimburse or
compensate Lessor for any liability, expense, loss or damage which Lessor may
suffer or incur by reason thereof. If Lessor uses or applies all or any portion
of the Security Deposit, Lessee shall within 10 days after written request
therefor deposit monies with Lessor sufficient to restore said Security Deposit
to the full amount required by this Lease. If the Base Rent increases during the
term of this Lease, Lessee shall, upon written request from Lessor, deposit
additional moneys with Lessor so that the total amount of the Security Deposit
shall at all times bear the same proportion to the Increased Base Rent as the
initial Security Deposit bore to the initial Base Rent. Should the Agreed Use be
amended to accommodate a material change in the business of Lessee or to
accommodate a sublessee or assignee, Lessor shall have the right to increase the
Security Deposit to the extent necessary, in Lessor's reasonable judgment, to
account for any increased wear and tear that the Premises may suffer as a result
thereof. If a change in control of Lessee occurs during this Lease and following
such change the financial condition of Lessee is, in Lessor's reasonable
judgment, significantly reduced, Lessee shall deposit such additional monies
with Lessor as shall be sufficient to cause the Security Deposit to be at a
commercially reasonable level based on such change in financial condition.
Lessor shall not be required to keep the Security Deposit separate from its
general accounts. Within 14 days after the expiration or termination of this
Lease, if Lessor elects to apply the Security Deposit only to unpaid Rent, and
otherwise within 30 days after the Premises have been vacated pursuant to
Paragraph 7.4(c) below, Lessor shall return that portion of the Security Deposit

not used or applied by Lessor. No part of the Security Deposit shall be
considered to be held in trust, to bear interest or to be prepayment for any
monies to be paid by Lessee under this Lease.

6. Use.

     6.1 Use. Lessee shall use and occupy the Premises only for the Agreed Use,
or any other legal use which is reasonably comparable thereto, and for no other
purpose. Lessee shall not use or permit the use of the Premises in a manner that
is unlawful, creates damage, waste or a nuisance, or that disturbs occupants of
or causes damage to neighboring premises or properties. Lessor shall not
unreasonably withhold or delay its consent to any written request for a
modification of the Agreed Use, so long as the same will not impair the
structural integrity of the improvements on the Premises or the mechanical or
electrical systems therein, and/or is not significantly more burdensome to the
Premises. If Lessor elects to withhold consent, Lessor shall within 7 days after
such request give written notification of same, which notice shall include an
explanation of Lessor's objections to the change in the Agreed Use.

     6.2 Hazardous Substances.

          (a) Reportable Uses Require Consent. The term "Hazardous Substance" as
used in this Lease shall mean any product, substance, or waste whose presence,
use, manufacture, disposal, transportation, or release, either by itself or in
combination with other materials expected to be on the Premises, is either: (i)
potentially injurious to the public health, safety or welfare, the environment
or the Premises, (ii) regulated or monitored by any governmental authority, or
(iii) a basis for potential liability of Lessor to any governmental agency or
third party under any applicable statute or common law theory. Hazardous
Substances shall include, but not be limited to, hydrocarbons, petroleum,
gasoline, and/or crude oil or any products, by-products or fractions thereof.
Lessee shall not engage in any activity in or on the Premises which constitutes
a Reportable Use of Hazardous Substances without the express prior written
consent of Lessor and timely compliance (at Lessee's expense) with all
Applicable Requirements. "Reportable Use" shall mean (i) the installation or use
of any above or below ground storage tank, (ii) the generation, possession,
storage, use, transportation, or disposal of a Hazardous Substance that requires
a permit from, or with respect to which a report, notice, registration or
business plan is required to be filed with, any governmental authority, and/or
(iii) the presence at the Premises of a Hazardous Substance with respect to
which any Applicable Requirements requires that a notice be given to persons
entering or occupying the Premises or neighboring properties. Notwithstanding
the foregoing, Lessee may use any ordinary and customary materials reasonably
required to be used in the normal course of the Agreed Use, ordinary office
supplies (copier toner, liquid paper, glue, etc.) and common household cleaning
materials, so long as such use is in compliance with all Applicable
Requirements, is not a Reportable Use, and does not expose the Premises or
neighboring property to any meaningful risk of contamination or damage or expose
Lessor to any liability therefor. In addition, Lessor may condition its consent
to any Reportable Use upon receiving such additional assurances as Lessor
reasonably deems necessary to protect itself, the public, the Premises and/or
the environment against damage, contamination, injury and/or liability,
including, but not limited to, the installation (and removal on or before Lease
expiration or termination) of protective modifications (such as concrete
encasements) and/or increasing the Security Deposit.

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

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

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

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

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

          (g) Termination Option. If a Hazardous Substance Condition (see
Paragraph 9.1(a)) occurs during the term of this Lease, unless Lessee is legally
responsible therefor (in which case Lessee shall make the investigation and
remediation thereof required by the Applicable Requirements and this Lease shall
continue in full force and effect, but subject to Lessor's rights under
Paragraph 6.2(d) and Paragraph 13), Lessor or Lessee may, at their
option, either (i) investigate and remediate such Hazardous Substance Condition,
if required, as soon as reasonably possible at their expense, in which
event this Lease shall continue in full force and effect, or (ii) if the
estimated cost to remediate such condition exceeds 12 times the then monthly
Base Rent or $100,000, whichever is greater, give written notice to the other,
within 30 days after receipt by either party of knowledge of the occurrence of
such Hazardous Substance Condition, of Lessor or Lessee's desire to terminate
this Lease as of the date 60 days following the date of such notice. In the
event Lessor elects to give a termination notice, Lessee may, within 10 days
thereafter, give written notice to Lessor of Lessee's commitment to pay the
amount by which the cost of the remediation of such Hazardous Substance
Condition exceeds an amount equal to 12 times the then monthly Base Rent or
$100,000, whichever is greater. Lessee shall provide Lessor with said funds or
satisfactory assurance thereof within 30 days following such commitment. In such
event, this Lease shall continue in full force and effect, and Lessor shall
proceed to make such remediation as soon as reasonably possible after the
required funds are available. If Lessee does not give such notice and provide
the required funds or assurance thereof within the time provided, this Lease
shall terminate as of the date specified in Lessor's notice of termination.

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

     6.4 Inspection; Compliance. Lessor and Lessor's "Lender" (as defined in
Paragraph 30) and consultants shall have the right to enter into Premises at any
time, in the case of an emergency, and otherwise at reasonable times after
reasonable notice, for the purpose of inspecting the condition of the Premises
and for verifying compliance by Lessee with this Lease. The cost of any such
inspections shall be paid by Lessor, unless a violation of Applicable
Requirements, or a Hazardous Substance Condition (see paragraph 9.1) is found to
exist or be imminent, or the inspection is requested or ordered by a
governmental authority. In such case, Lessee shall upon request reimburse Lessor
for the cost of such inspection, so long as such inspection is reasonably
related to the violation or contamination. In addition, Lessee shall provide
copies of all relevant material safety data sheets (MSDS) to Lessor within 10
days of the receipt of a written request therefor.

                                     REVISED                    FORM STN-7-4/01E



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

          (b) Service Contracts. Lessee shall, at Lessee's sole expense, procure
and maintain contracts, with copies to Lessor, in customary form and substance
for, and with contractors specializing and experienced in the maintenance of the
following equipment and improvements, if any, if and when installed on the
Premises: (i) HVAC equipment, (ii) boiler, and pressure vessels, (iii) fire
extinguishing systems, including fire alarm and/or smoke detection, (iv)
landscaping and irrigation systems, (v) roof covering and drains, (vi)
clarifiers (vii) basic utility feed to the perimeter of the Building, and (viii)
any other equipment, if reasonably required by Lessor. However, Lessor reserves
the right, upon notice to Lessee, to procure and maintain any or all of such
service contracts, and if Lessor so elects, Lessee shall reimburse Lessor, upon
demand, for the cost thereof.

          (c) Failure to Perform. If Lessee fails to perform Lessee's
obligations under this Paragraph 7.1, Lessor may enter upon the Premises after
10 days' prior written notice to Lessee (except in the case of an emergency, in
which case no notice shall be required), perform such obligations on Lessee's
behalf, and put the Premises in good order, condition and repair, and Lessee
shall promptly pay to Lessor a sum equal to 115% of the cost thereof.

          (d) Replacement. Subject to Lessee's Indemnification of Lessor as set
forth in Paragraph 8.7 below, and without relieving Lessee of liability
resulting from Lessee's failure to exercise and perform good maintenance
practices, if an item described in Paragraph 7.1(b) cannot be repaired other
than at a cost which is in excess of 50% of the cost of replacing such item,
then such item shall be replaced by Lessor, and the cost thereof shall be
prorated between the Parties and Lessee shall only be obligated to pay, each
month during the remainder of the term of this Lease, on the date on which Base
Rent is due, an amount equal to the product of multiplying the cost of such
replacement by a fraction, the numerator of which is one, and the denominator of
which is 144 (i.e. 1/144th of the cost per month). Lessee shall pay interest on
the unamortized balance at a rate that is commercially reasonable in the
judgment of Lessor's accountants. Lessee may, however, prepay its obligation at
any time.

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

     7.3 Utility Installations; Trade Fixtures; Alterations.

          (a) Definitions. The term "Utility Installations" refers to all floor
and window coverings, air and/or vacuum lines, power panels, electrical
distribution, security and fire protection systems, communication cabling,
lighting fixtures, HVAC equipment, plumbing, and fencing in or on the Premises.
The term "Trade Fixtures" shall mean Lessee's machinery and equipment that can
be removed without doing material damage to the Premises. The term "Alterations"
shall mean any modification of the improvements, other than Utility
Installations or Trade Fixtures, whether by addition or deletion. "Lessee Owned
Alterations and/or Utility Installations" are defined as Alterations and/or
Utility Installations made by Lessee that are not yet owned by Lessor pursuant
to Paragraph 7.4(a).

          (b) Consent. Lessee shall not make any Alterations or Utility
Installations to the Premises without Lessor's prior written consent. Lessee
may, however, make non-structural Utility Installations to the interior of the
Premises (excluding the roof) without such consent but upon notice to Lessor, as
long as they are not visible from the outside, do not involve puncturing,
relocating or removing the roof or any existing walls, will not affect the
electrical, plumbing, HVAC, and/or life safety systems, and the cumulative cost
thereof during this Lease as extended does not exceed a sum equal to 3 month's
Base Rent in the aggregate or a sum equal to one month's Base Rent in any one
year. Notwithstanding the foregoing, Lessee shall not make or permit any roof
penetrations and/or install anything on the roof without the prior written
approval of Lessor. Lessor may, as a precondition to granting such approval,
require Lessee to utilize a contractor chosen and/or approved by Lessor. Any
Alterations or Utility Installations that Lessee shall desire to make and which
require the consent of the Lessor shall be presented to Lessor in written form
with detailed plans. Consent shall be deemed conditioned upon Lessee's: (i)
acquiring all applicable governmental permits, (ii) furnishing Lessor with
copies of both the permits and the plans and specifications prior to
commencement of the work, and (iii) compliance with all conditions of said
permits and other Applicable Requirements in a prompt and expeditious manner.
Any Alterations or Utility Installations shall be performed in a workmanlike
manner with good and sufficient materials. Lessee shall promptly upon completion
furnish Lessor with as-built plans and specifications. For work which costs an
amount in excess of one month's Base Rent, Lessor may condition its consent upon
Lessee providing a lien and completion bond in an amount equal to 150% of the
estimated cost of such Alteration or Utility Installation and/or upon Lessee's
posting an additional Security Deposit with Lessor.

          (c) Liens; Bonds. 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 Promises, which claims are or may be secured by any mechanic's or
materialmen's lien against the Premises or any interest therein. Lessee shall
give Lessor not less than 10 days notice prior to the commencement of any work
in, on or about the Premises, and Lessor shall have the right to post notices of
non-responsibility. If Lessee shall contest the validity of any such lien, claim
or demand, then Lessee shall, at its sole expense defend and protect itself,
Lessor and the Premises against the same and shall pay and satisfy any such
adverse judgment that may be rendered thereon before the enforcement thereof. If
Lessor shall require, Lessee shall furnish a surety bond in an amount equal to
150% of the amount of such contested lien, claim or demand, indemnifying Lessor
against liability for the same. If Lessor elects to participate in any such
action, Lessee shall pay Lessor's attorneys' fees and costs.

     7.4 Ownership; Removal; Surrender; and Restoration.

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

          (b) Removal. By delivery to Lessee of written notice from Lessor not
earlier than 90 and not later than 30 days prior to the end of the term of this
Lease, Lessor may require that any or all Lessee Owned Alterations or Utility
Installations be removed by the expiration or termination of this Lease. Lessor
may require the removal at any time of all or any part of any Lessee Owned
Alterations or Utility Installations made without the required consent.

          (c) Surrender; Restoration. Lessee shall surrender the Premises by the
Expiration Date or any earlier termination date, with all of the improvements,
parts and surfaces thereof broom clean and free of debris, and in good operating
order, condition and state of repair, ordinary wear and tear excepted. "Ordinary
wear and tear" shall not include any damage or deterioration that would have
been prevented by good maintenance practice. Notwithstanding the foregoing, if
this Lease is for 12 months or less, then Lessee shall surrender the Premises in
the same condition as delivered to Lessee on the Start Date with NO allowance
for ordinary wear and tear. Lessee shall repair any damage occasioned by the
installation, maintenance or removal of Trade Fixtures, Lessee owned Alterations
and/or Utility Installations, furnishings, and equipment as well as the removal
of any storage tank installed by or for Lessee. Lessee shall completely remove
from the Premises any and all Hazardous Substances brought onto the Premises by
or for Lessee, or any third party (except Hazardous Substances which were
deposited via underground migration from areas outside of the Premises, or if
applicable, the Project) even if such removal would require Lessee to perform or
pay for work that exceeds statutory requirements. Trade Fixtures shall remain
the property of Lessee and shall be removed by Lessee. Any personal property of
Lessee not removed on or before the Expiration Date or any earlier termination
date shall be deemed to have been abandoned by Lessee and may be disposed of or
retained by Lessor as Lessor may desire. The failure by Lessee to timely vacate
the Premises pursuant to this Paragraph 7.4(c) without the express written
consent of Lessor shall constitute a holdover under the provisions of Paragraph
26 below.

8. Insurance; Indemnity.

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

     8.2 Liability Insurance.

          (a) Carried by Lessee. Lessee shall obtain and keep in force a
Commercial General Liability policy of insurance protecting Lessee and Lessor as
an additional insured against claims for bodily injury, personal injury and
property damage based upon or arising out of the ownership, use occupancy or
maintenance of the Premises and all areas appurtenant thereto. Such insurance
shall be on an occurrence basis providing single limit coverage in an amount not
less than $1,000,000 per occurrence with an annual aggregate of not less than
$2,000,000, an "Additional Insured-Managers or Lessors of Premises Endorsement"
and contain the "Amendment of the Pollution Exclusion Endorsement" for damage
caused by heat, smoke or fumes from a hostile fire. The policy shall not contain
any intra-insured exclusions as between insured persons or organizations, but
shall include coverage for liability assumed under this Lease as an "insured
contract" for the performance of Lessee's indemnity obligations under this
Lease. The limits of said insurance shall not, however, limit the liability of
Lessee nor relieve Lessee of any obligation hereunder. All insurance carried by
Lessee shall be primary to and not contributory with any similar insurance
carried by Lessor, whose insurance shall be considered excess insurance only.

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

     8.3 Property Insurance - Building, Improvements and Rental Value.

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

          (b) Rental Value.

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

     8.4 Lessee's Property; Business Interruption Insurance.

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

          (b) Business Interruption. Lessee shall obtain and maintain loss of
income and extra expense insurance in amounts as will reimburse Lessee for
direct or indirect loss of earnings attributable to all perils commonly insured
against by prudent lessees in the business of Lessee or attributable to
prevention of access to the Premises as a result of such perils.

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

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

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

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

     8.8 Exemption of Lessor from Liability. Lessor shall not be liable for
injury or damage to the person or goods, wares, merchandise or other property of
Lessee, Lessee's employees, contractors, invitees, customers, or any other
person in or about the Premises, whether such damage or injury is caused by or
results from fire, steam, electricity, gas, water or rain, or from the breakage,
leakage, obstruction or other defects of pipes, fire sprinklers, wires,
appliances, plumbing, HVAC or lighting fixtures, or from any other cause,
whether the said injury or damage results from conditions arising upon the
Premises or upon other portions of the building of which the Premises are a
part, or from other sources or places. Lessor shall not be liable for any
damages arising from any act or neglect of any other tenant of Lessor nor from
the failure of Lessor to enforce the provisions of any other lease in the
Project. Notwithstanding Lessor's negligence or breach of this Lease. Lessor
shall under no circumstances be liable for injury to Lessee's business or for
any loss of income or profit therefrom.

     8.9 Failure to Provide Insurance. Lessee acknowledges that any failure on
its part to obtain or maintain the insurance required herein will expose Lessor
to risks and potentially cause Lessor to Incur costs not contemplated by this
Lease, the extent of which will be extremely difficult to ascertain.
Accordingly, for any month or portion thereof that Lessee does not maintain the
required insurance and/or does not provide Lessor with the required binders or
certificates evidencing the existence of the required insurance, the Base Rent
shall be automatically Increased, without any requirement for notice to Lessee,
by an amount equal to 10% of the then existing Base Rent or $100, whichever is
greater. The parties agree that such increase in Base Rent represents fair and
reasonable compensation for the additional risk/ costs that Lessor will incur by
reason of Lessee's failure to maintain the required insurance. Such increase in
Base Rent shall in no event constitute a waiver of Lessee's Default or Breach
with respect to the failure to maintain such insurance, prevent the exercise of
any of the other rights and remedies granted hereunder, nor relieve Lessee of
its obligation to maintain the insurance specified in this Lease.

9. Damage or Destruction.

     9.1 Definitions.

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

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

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

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

          (e) "Hazardous Substance Condition" shall mean the occurrence or
discovery of a condition involving the presence of, or a contamination by, a
Hazardous Substance as defined in Paragraph 8.2(a), in, on, or under the
Premises which requires repair, remediation, or restoration.

     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 any
applicable 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 (except as to
the deductible which is Lessee's responsibility) as and when required to
complete said repairs. In the event, however, such shortage was due to the fact
that, by reason of the unique nature of the improvements, full replacement cost
insurance coverage was not commercially reasonable and available. Lessor shall
have no obligation to pay for the shortage in insurance proceeds or to fully
restore the unique aspects of the Premises unless Lessee provides Lessor with
the funds to cover same, or adequate assurance thereof, within 10 days following
receipt of written notice of such shortage and request therefor. If Lessor
receives said funds or adequate assurance thereof within said 10 day period, the
party responsible for making the repairs shall complete them as soon as
reasonably possible and this Lease shall remain in full force and effect. If
such funds or assurance are not received, Lessor may nevertheless elect by
written notice to Lessee within 10 days thereafter to; (i) make such restoration
and repair as is commercially reasonable with Lessor paying any shortage in
proceeds, in which case this Lease shall remain in full force and effect, or
(ii)

have this Lease terminate 30 days thereafter. Lessee shall not be entitled to
reimbursement of any funds contributed by Lessee to repair any such damage or
destruction. Premises Partial Damage due to flood or earthquake shall be subject
to Paragraph 9.3, notwithstanding that there may be some insurance coverage, but
the net proceeds of any such insurance shall be made available for the repairs
if made by either Party.

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

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

     9.5 Damage Near End of Term, if at any time during the last 6 months of
this Lease there is damage for which the cost to repair exceeds one month's Base
Rent, whether or not an Insured Loss, Lessor may terminate this Lease effective
6O days following the date of occurrence of such damage by giving a written
termination notice to Lessee within 30 days after the date of occurrence of such
damage. Notwithstanding the foregoing, if Lessee at that time has an exercisable
option to extend this Lease or to purchase the Premises, then Lessee may
preserve this Lease by, (a) exercising such option and (b) providing Lessor with
any shortage in insurance proceeds (or adequate assurance thereof) needed to
make the repairs on or before the earlier of (i) the date which is 10 days after
Lessee's receipt of Lessor's written notice purporting to terminate this Lease,
or (ii) the day prior to the date upon which such option expires. If Lessee duly
exercises such option during such period and provides Lessor with funds (or
adequate assurance thereof) to cover any shortage in insurance proceeds, Lessor
shall, at Lessor's commercially reasonable expense, repair such damage as soon
as reasonably possible and this Lease shall continue in full force and effect.
If Lessee fails to exercise such option and provide such funds or assurance
during such period, then this Lease shall terminate on the date specified in the
termination notice and Lessee's option snail be extinguished.

     9.6 Abatement of Rent; Lessee's Remedies.

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

          (b) Remedies. If Lessor shall be obligated to repair or restore the
Premises and does not commence, in a substantial and meaningful way, such repair
or restoration within 9O 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 60 days
following the giving of such notice. If Lessee gives such notice and such repair
or restoration is not commenced within 30 days thereafter, this Lease shall
terminate as of the date specified in said notice. If the repair or restoration
is commenced within such 30 days, this Lease shall continue in full force and
effect. "Commence" 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 Termination; Advance Payments. Upon termination of this Lease pursuant
to Paragraph 6.2(g) or Paragraph 9, an equitable adjustment shall be made
concerning advance Base Rent and any other advance payments made by Lessee to
Lessor. Lessor shall, in addition, return to Lessee so much of Lessee's Security
Deposit as has not been, or is not then required to be, used by Lessor.

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

10. Real Property Taxes.

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

     10.2 Payment of Taxes. In addition to Base Rent, Lessee shall pay to Lessor
in amount equal to the Real Property Tax installment due at least 20 days prior
to the applicable delinquency date. If any such installment shall cover any
period of time prior to or after the expiration or termination of this Lease,
Lessee's share of such installment shall be prorated. In the event Lessee incurs
a late charge on any Rent payment, Lessor may estimate the current Real Property
Taxes, and require, that such taxes be paid in advance to Lessor by Lessee
monthly in advance with the payment of the Base Rent. Such monthly payments
shall be an amount equal to the amount of the estimated installment of taxes
divided by the number of months remaining before the month in which said
installment becomes delinquent. When the actual amount of the applicable tax
bill is known, the amount of such equal monthly advance payments shall be
adjusted as required to provide the funds needed to pay the applicable taxes. If
the amount collected by Lessor is Insufficient to pay such Real Property Taxes
when due, Lessee shall pay Lessor, upon demand, such additional sum as is
necessary. Advance payments may be intermingled with other moneys of Lessor and
shall not bear interest. In the event of a Breach by Lessee in the performance
of its obligations under this Lease, then any such advance payments may be
treated by Lessor as an additional Security Deposit.

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

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

11. Utilities and Services. 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 or billed to Lessee, Lessee shall pay a reasonable
proportion, to be determined by Lessor, of all charges jointly metered or
billed. There shall be no abatement of rent and Lessor shall not be liable in
any respect whatsoever for the inadequacy, stoppage, interruption or
discontinuance of any utility or service due to riot, strike, labor dispute,
breakdown, accident, repair or other cause beyond Lessor's reasonable control or
in cooperation with governmental request or directions.

12. Assignment and Subletting.

     12.1 Lessor's Consent Required.

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

          (b) Unless Lessee is a corporation and its stock is publicly traded on
a national stock exchange, a change in the control of Lessee shall constitute an
assignment requiring consent. The transfer, on a cumulative basis, of 25% or
more of the voting control of Lessee shall constitute a change in control for
this purpose.

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

          (d) An assignment or subletting without consent shall, at Lessor's
option, be a Default curable after notice per Paragraph 13.1(c), or a noncurable
Breach without the necessity of any notice and grace period. If Lessor elects to
treat such unapproved assignment of subletting as a noncurable Breach, Lessor
may either (i) terminate this Lease, or (ii) upon 30 days written notice,
increase the monthly Base Rent to 110% of the Base Rent then in effect. Further,
in the event of such Breach and rental adjustment, (i) the purchase price of any
option to purchase the Premises held by Lessee shall be subject to similar
adjustment to 110% of the price previously in effect, and (ii) all fixed and
non-fixed rental adjustments scheduled during the remainder of the Lease term
shall be increased to 110% of the scheduled adjusted rent.

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

     12.2 Terms and Conditions Applicable to Assignment and subletting.

          (a) Regardless of Lessor's consent, no assignment or subletting shall:
(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) after the primary liability of Lessee for
the payment of Rent or for the performance of any other obligations to be
performed by Lessee.

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

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

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

          (e) Each request for consent to an assignment or subletting shall be
in writing, accompanied by information relevant to Lessor's determination as to
the financial and operational responsibility and appropriateness of the proposed
assignee or sublessee, including but not limited to the intended use and/or
required modification of the Premises, if any, together with a fee of $500 as
consideration for Lessor's considering and processing said request. Lessee
agrees to provide Lessor with such other or additional information and/or
documentation as may be reasonably requested. (See also Paragraph 36)

          (f) Any assignee of, or sublessee under, this Lease shall, by reason
of accepting such assignment or entering into such sublease, be deemed to have
assumed and agreed to conform and comply with each and every term, covenant,
condition and obligation herein to be observed or performed by Lessee during the
term of said assignment or sublease, other than such obligations as are contrary
to or inconsistent with provisions of an assignment or sublease to which Lessor
has specifically consented to in writing.

          (g) Lessor's consent to any assignment or subletting shall not
transfer to the assignee or sublessee any Option granted to the original Lessee
by this Lease unless such transfer is specifically consented to by Lessor in
writing. (See Paragraph 39.2)

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

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

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

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

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

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

13. Default; Breach; Remedies.

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

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

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

          (c) The failure by Lessee to provide (i) reasonable written evidence
of compliance with Applicable Requirements, (ii) the service contracts, (iii)
the rescission of an unauthorized assignment or subletting, (iv) an Estoppel
Certificate, (v) a requested subordination, (vi) evidence concerning any
guaranty and/or Guarantor, (vii) any document requested under Paragraph 42,
(vii) material safety data sheets (MSDS), or (ix) 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 10 days following
written notice to Lessee.

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

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

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

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

     13.2 Remedies. If Lessee fails to perform any of its affirmative duties or
obligations, within 10 days after written notice (or in case of an emergency,
without notice), Lessor may, at its option, perform such duty or obligation on
Lessee's behalf, including but not limited to the obtaining of reasonably
required bonds, insurance policies, or governmental licenses, permits or
approvals. Lessee shall pay to Lessor an amount equal to 115% of the costs and
expenses incurred by Lessor in such performance upon receipt of an invoice
therefor. In the event of a Breach, Lessor may, with or without further notice
or demand, and without limiting Lessor in the exercise of any right or remedy
which Lessor may have by reason of such Breach:

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

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

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

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

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

     13.4 Late Charges. Lessee hereby acknowledges that late payment by Lessee
of Rent will cause Lessor to incur costs not contemplated by this Lease, the
exact amount of which will be extremely difficult to ascertain. Such costs
include, but are not limited to, processing and accounting charges, and late
charges which may be imposed upon Lessor by any Lender. Accordingly, If any Rent
shall not be received by Lessor within 5 days after such amount shall be due,
then, without any requirement for notice to Lessee, Lessee shall immediately pay
to Lessor a one-time late charge equal to 10% of each such overdue amount or
$100, whichever is greater. The Parties hereby agree that such late charge
represents a fair and reasonable estimate of the costs Lessor will incur by
reason of such late payment. Acceptance of such late charge by Lessor shall in
no event constitute a waiver of Lessee's Default or Breach with respect to such
overdue amount, nor prevent the exercise of any of the other rights and remedies
granted hereunder. In the event that a late charge is payable hereunder, whether
or not collected, for 3 consecutive installments of Base Rent, then
notwithstanding any provision of this Lease to the contrary, Base Rent shall, at
Lessor's option, become due and payable quarterly in advance.

     13.5 Interest. Any monetary payment due Lessor hereunder, other than late
charges, not received by Lessor, when due as to scheduled payments (such as Base
Rent) or within 30 days following the date on which it was due for non-scheduled
payment, shall bear Interest from the date when due, as to scheduled payments,
or the 31st day after it was due as to non-scheduled payments. The interest
("Interest") charged shall be computed at the rate of 10% per annum but shall
not exceed the maximum rate allowed by law. Interest is payable in addition to
the potential late charge provided for in Paragraph 13.4.

     13.6 Breach by Lessor.

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

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

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

15. Brokerage Fees.

     15.1 Additional Commission. In addition to the payments owed pursuant to
Paragraph 1.9 above, and unless Lessor and the Brokers otherwise agree in
writing, Lessor agrees that: (a) if Lessee exercises any Option, (b) if Lessee
acquires any rights to the Premises or other premises owned by Lessor and
located within the same Project, if any, within which the Premises is located,
(c) if Lessee remains in possession of the Premises, with the consent of Lessor,
after the expiration of this Lease, or (d) if Base Rent is increased, whether by
agreement or operation of an escalation clause herein, then, Lessor shall pay
Brokers a fee in accordance with the schedule of the Brokers in effect at the
time of the execution of this Lease.

     15.2 Assumption of Obligations. Any buyer or transferee of Lessor's
interest in this Lease shall be deemed to have assumed Lessor's obligation
hereunder. Brokers shall be third party beneficiaries of the provisions of
Paragraphs 1.9, 15, 22 and 31. If Lessor fails to pay to Brokers any amounts due
as and for brokerage fees pertaining to this Lease when due, then such amounts
shall accrue Interest. In addition, if Lessor fails to pay any amounts to
Lessee's Broker when due, Lessee's Broker may send written notice to Lessor and
Lessee of such failure and if Lessor fails to pay such amounts within 10 days
after said notice, Lessee shall pay said monies to its Broker and offset such
amounts against Rent. In addition, Lessee's Broker shall be deemed to be a third
party beneficiary of any commission agreement entered into by and/or between
Lessor and Lessor's Broker for the limited purpose of collecting any brokerage
fee owed.

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

16. Estoppel Certificates.

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

          (b) If the Responding Party shall fail to execute or deliver the
Estoppel Certificate within such 10 day period, the Requesting Party may execute
an Estoppel Certificate stating that: (i) the Lease is in full force and effect
without modification except as may be represented by the Requesting Party, (ii)
there are no uncured defaults in the Requesting Party's performance, and (iii)
if Lessor is the Requesting Party, not more than one month's rent has been paid
in advance. Prospective purchasers and encumbrances may rely upon the Requesting
Party's Estoppel Certificate, and the Responding Party shall be estopped from
denying the truth of the facts contained in said Certificate.

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

17. Definition of Lessor. The term "Lessor" as used herein shall mean the owner
or owners at the time in question of the fee title to the Premises, or, if this
is a sublease, of the Lessee's interest in the prior lease. In the event of a
transfer of Lessor's title or interest in the Premises or this Lease. Lessor
shall deliver to the transferee or assignee (in cash or by credit) any unused
Security Deposit held by Lessor. Except as provided in Paragraph 15, upon such
transfer or assignment and delivery of the Security Deposit, as aforesaid, the
prior Lessor shall be relieved of all liability with respect to the obligations
and/or covenants under this Lease thereafter to be performed by the Lessor.
Subject to the foregoing, the obligations and/or covenants in this Lease to be
performed by the Lessor shall be binding only upon the Lessor as hereinabove

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

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

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

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

22. No Prior or Other Agreements; Broker Disclaimer. This Lease contains all
agreements between the Parties with respect to any matter mentioned herein, and
no other prior 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 use, nature, quality and character of the Premises. Brokers have no
responsibility with respect thereto or with respect to any default or breach
hereof by either Party. The liability (including court costs and attorneys'
fees), of any Broker with respect to negotiation, execution, delivery or
performance by either Lessor or Lessee under this Lease or any amendment of
modification hereto shall be limited to an amount up to the fee received by such
Broker pursuant to this Lease; provided, however, that the foregoing limitation
on each Broker's liability shall not be applicable to any gross negligence or
willful misconduct of such Broker.

23. Notices.

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

     23.2 Date Of Notice. Any notice sent by registered or certified mail,
return receipt requested, shall be deemed given on the date of delivery shown on
the receipt card, or if no delivery date is shown, the postmark thereon. If sent
by regular mail the notice shall be deemed given 48 hours after the same is
addressed as required herein and mailed with postage prepaid. Notices delivered

delivered via delivery or mail. If notice is received on a Saturday, Sunday or
legal holiday, it shall be deemed received on the next business day.

24. Waivers. No waiver by Lessor of the Default or Breach of any term, covenant
or condition hereof by Lessee, shall be deemed a waiver of any other term,
covenant or condition hereof, or of any subsequent Default or Breach by Lessee
of the same or of any other term, covenant or condition hereof. Lessor's consent
to, or approval of, any act shall not be deemed to render unnecessary the
obtaining of Lessor's consent to, or approval of, any subsequent or similar act
by Lessee, or be construed as the basis of an estoppel to enforce the provision
or provisions of this Lease requiring such consent. The acceptance of Rent by
Lessor shall not be a waiver of any Default or Breach by Lessee. Any payment 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. Disclosures Regarding the Nature of a Real Estate Agency Relationship.

          (a) When entering into a discussion with a real estate agent regarding
a real estate transaction, a Lessor or Lessee should from the outset understand
what type of agency relationship or representation it has with the agent or
agents in the transaction. Lessor and Lessee acknowledge being advised by the
Brokers in this transaction, as follows:

               (I) Lessor's Agent. A Lessor's agent under a listing agreement
with the Lessor acts as the agent for the Lessor only. A lessor's agent or
subagent has the following affirmative obligations: To the Lessor; A fiduciary
duty of utmost care, integrity, honesty, and loyalty in dealings with the
Lessor. To the Lessee and the Lessor; a. Diligent exercise of reasonable skills
and care in performance of the agent's duties. b. A duty of honest and fair
dealing and good faith. c. A duty to disclose all facts known to the agent
materially affecting the value or desirability of the property that are not
known to, or within the diligent attention and observation of, the Parties. An
agent is not obligated to reveal to either Party any confidential information
obtained from the other Party which does not involve the affirmative duties set
forth above.

               (II) Lessee's Agent. An agent can agree to act as agent for the
Lessee only. In these situations, the agent is not the Lessor's agent, even if
by agreement the agent may receive compensation for services rendered, either in
full or in part from the Lessor. An agent acting only for a Lessee has the
following affirmative obligations. To the Lessee: A fiduciary duty of utmost
care, integrity, honesty, and loyalty in dealings with the Lessee. To the Lessee
and the Lessor: a. Diligent exercise of reasonable skills and care in
performance of the agent's duties. b. A duty of honest and fair dealing and good
faith. c. A duty to disclose all facts known to the agent materially affecting
the value or desirability of the property that are not known to, or within the
diligent attention and observation of, the Parties. An agent is not obligated to
reveal to either Party any confidential information obtained from the other
Party which does not involve the affirmative duties set forth above.

               (III) Agent Representing Both Lessor and Lessee. A real estate
agent, either acting directly or through one or more associate licenses, can
legally be the agent of both the Lessor and the Lessee in a transaction, but
only within the knowledge and consent of both the Lessor and the Lessee. In a
dual agency situation, the agent has the following affirmative obligations to
both the Lessor and the Lessee: a. A fiduciary duty of utmost care, integrity,
honesty and loyalty in the dealings with either Lessor or the Lessee. b. Other
duties to the Lessor and the Lessee as stated above in subparagraphs (i) or
(ii). In representing both Lessor and Lessee, the agent may not without the
express permission of the respective Party, disclose to the other Party that the
Lessor will accept rent in an amount less than that indicated in the listing or
that the Lessee is willing to pay a higher rent than that offered. The above
duties of the agent in a real estate transaction do not relieve a Lessor or
Lessee from the responsibility to protect their own interests. Lessor and Lessee
should carefully read all agreements to assure that they adequately express
their understanding of the transaction. A real estate agent is a person
qualified to advise about real estate. If legal or tax advice is desired,
consult a competent professional.

          (b) Brokers have no responsibility with respect to any default or
breach hereof by either Party. The liability (including court costs and
attorneys' fees), of any Broker with respect to any breach of duty, error or
omission relating to this Lease shall not exceed the fee received by such Broker
pursuant to this Lease; provided, however, that the foregoing limitation on each
Broker's liability shall not be applicable to any gross negligence or willful
misconduct of such Broker.

          (c) Lessor and Lessee agree to identify to Brokers as "Confidential"
any communication or information given Brokers that is considered by such Party
to be confidential.

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

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

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

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

30. Subordination; Attornment; Non-Disturbance.

     30.1 Subordination. This Lease and any Option granted hereby shall be
subject and subordinate to any ground lease, mortgage, deed of trust, or other
hypothecation or security device (collectively, "Security Device"), now or
hereafter placed upon the Premises, to any and all advances made

on the security thereof, and to all renewals, modifications, and extensions
thereof. Lessee agrees that the holders of any such Security Devices (in this
Lease together referred to as "Lender") shall have no liability or obligation to
perform any of the obligations of Lessor under this Lease. Any Lender may elect
to have this Lease and/or any Option granted hereby superior to the lien of its
Security Device by giving written notice thereof to Lessee, whereupon this Lease
and such Options shall be deemed prior to such Security Device, notwithstanding
the relative dates of the documentation or recordation thereof.

     30.2 Attornment. In the event that Lessor transfers title to the Premises,
or the Premises are acquired by another upon the foreclosure or termination of a
Security Device to which this Lease is Subordinated (i) Lessee shall, subject to
the non-disturbance provisions of Paragraph 30.3, attorn to such new owner, and
upon request, enter into a new lease, containing all of the terms and provisions
of this Lease, with such new owner for the remainder of the term hereof, or, at
the election of such new owner, this Lease shall automatically become a new
Lease between Lessee and such new owner, upon all of the terms and conditions
hereof, for the remainder of the term hereof, and (ii) Lessor shall thereafter
be relieved of any further obligations hereunder and such new owner shall assume
all of Lessor's obligations hereunder, except that such new owner shall not: (a)
be liable for any act or omission of any prior lessor or with respect to events
occurring prior to acquisition of ownership; (b) be subject to any offsets or
defenses which Lessee might have against any prior lessor, (c) be bound by
prepayment of more than one month's rent, or (d) be liable for the return of any
security deposit paid to any prior lessor.

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

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

31. Attorneys' Fees. If any Party or Broker brings an action or proceeding
involving the Premises whether founded in tort, contract or equity, or to
declare rights hereunder, the Prevailing Party (as hereafter defined) in any
such proceeding, action, or appeal thereon, shall be entitled to reasonable
attorneys' fees. Such fees may be awarded in the same suit or recovered in a
separate suit, whether or not such action or proceeding is 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 attorneys' fees award
shall not be computed in accordance with any court fee schedule, but shall be
such as to fully reimburse all attorneys' fees reasonably incurred. In addition,
Lessor shall be entitled to attorneys' fees, costs and expenses incurred in the
preparation and service of notices of Default and consultations in connection
therewith, whether or not a legal action is subsequently commenced in connection
with such Default or resulting Breach ($200 is a reasonable minimum per
occurrence for such services and consultation).

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 after reasonable prior notice for the purpose
of showing the same to prospective purchasers, lenders, or tenants, and making
such alterations, repairs, improvements or additions to the Premises as Lessor
may deem necessary or desirable and the erecting, using and maintaining of
utilities, services, pipes and conduits through the Premises and/or other
premises as long as there is no material adverse effect to Lessee's use of the
Premises. All such activities shall be without abatement of rent or liability to
Lessee.

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

34. Signs. Lessor may place on the Premises ordinary "For Sale" signs at any
time and ordinary "For Lease" signs during the last 6 months of the term hereof.
Except for ordinary "for sublease" signs, Lessee shall not place any sign upon
the Premises without Lessor's prior written consent. All signs must comply with
all Applicable Requirements.

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

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

37. Guarantor.

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

     37.2 Default. It shall constitute a Default of the Lessee if any Guarantor
fails or refuses, upon request to provide: (a) evidence of the execution of the
guaranty, including the authority of the party signing on Guarantor's behalf to
obligate Guarantor, and in the case of a corporate Guarantor, a certified copy
of a resolution of its board of directors authorizing the making of such
guaranty, (b) current financial statements, (c) an Estoppel Certificate, or (d)
written confirmation that the guaranty is still in effect.

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

39. Options. If Lessee is granted an Option, as defined below, then the
following provisions shall apply:

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

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

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

     39.4 Effect of Default on Options.

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

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

          (c) An Option shall terminate and be of no further force or effect,
notwithstanding Lessee's due and timely exercise of the Option, if, after such
exercise and prior to the commencement of the extended term or completion of
the purchase, (i) Lessee fails to pay Rent for a period of 30 days after such
Rent becomes due (without any necessity of Lessor to give notice thereof), or
(ii) if Lessee commits a Breach of this Lease.

40. Multiple Buildings. If the Premises are a part of a group of buildings
controlled by Lessor, Lessee agrees that it will abide by and conform to all
reasonable rules and regulations which Lessor may make from time to time for the
management, safety, and care of said properties, including the care and

contractors and invitees to so abide and conform. Lessee also agrees to pay its
fair share of common expenses incurred in connection with such rules and
regulations.

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

43. Performance Under Protest. If at any time a dispute shall arise as to any
amount of sum of money to be paid by one Party to the other under the provisions

have the right to make payment "under protest" and such payment shall not be
regarded as a voluntary payment and there shall survive the right on the part of
said Party to institute suit for recovery of such sum. If it shall be adjudged
that there was no legal obligation on the part of said Party to pay such sum or
any part thereof, said Party shall be entitled to recover such sum or so much
thereof as it was not legally required to pay.

44. Authority; Multiple Parties; Execution.

          (a) If either Party hereto is a corporation, trust, limited liability

handwritten provisions.

46. Offer. Preparation of this Lease by either Party or their agent and

the other Party. This Lease is not intended to be binding until executed and
delivered by all Parties hereto.

47. Amendments. This Lease may be modified only in writing, signed by the

refinancing of the Premises.

48. Waiver of Jury Trial. THE PARTIES HEREBY WAIVE THEIR RESPECTIVE RIGHTS TO
