   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 square footage set forth in this Lease, or that may
have been used in calculating rental, is an approximation which Lessor and

have exclusive use of all parking located upon the Premises.

debris on the Commencement Date and warrants to Lessee that the existing
plumbing, fire sprinkler system, lighting, air conditioning, heating, and
loading doors, if any, in the Premises, other than those constructed by Lessee,
shall be in good operating condition on the Commencement Date. If a
non-compliance with said warranty exists as of the Commencement Date, Lessor
shall, except as otherwise provided in this Lease, promptly after receipt of
written notice from Lessee setting forth with specificity the nature and extent
of such non-compliance, rectify same at Lessor's expense. If Lessee does not
give Lessor written notice of a non-compliance with this warranty within one
hundred twenty (120) days after the Commencement Date, correction of that
non-compliance shall be the obligation of Lessee at Lessee's sole cost and
expense.

   2.3  INTENTIONALLY OMITTED

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

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

   2.6  LESSEE'S ACKNOWLEDGEMENT. Lessee acknowledges that as of the execution
of the Commencement Date it will have had an adequate opportunity to inspect the
Premises and to investigate its physical characteristics and conditions. Except
as expressly provided in Section 2.2 above, as of the execution of the
Commencement Date, Lessee shall be deemed to have waived any and all objections
to the physical characteristics and conditions of the Premises which would be
disclosed by a reasonable and diligent inspection. Lessee acknowledges that,
except as specifically provided in this Lease, neither Lessor nor any of its
employees, agents or representatives has made any representations, warranties or
agreements to or with Lessee on behalf of Lessor as to any matters concerning
the Premises, the use thereof, or the suitability of Lessee's intended use of
the Premises, and that Lessee accepts the Premises in their "AS-IS" condition.
Without limiting the generality of the foregoing, Lessee understands and agrees
that it leases the Premises without any representations or warranties by Lessor,
or by any official, employee or agent of Lessor, regarding the existence, use,
generation, manufacture, storage, transportation, release or disposal of
Hazardous Substances and/or oil wells and/or underground storage tanks and/or
pipelines on, under or about the Premises, or regarding whether the Premises is
or may be in violation of any federal, state or local law, ordinance or
regulation relating to Hazardous Substances and/or oil wells and/or underground
storage tanks and/or pipelines on, under or about the Premises, including
without limitation, soil and ground water conditions. Lessee acknowledges and
understands that it must perform is own "due diligence" with respect to all
environmental matters relating to the Premises, inclusive of any environmental
audits or assessments performed by or on behalf of Lessor.

     2.7  PURCHASE AND FINANCING CONTINGENCY. It is understood and agreed that
as of the date of this Lease, lessor does not own the real property described
in Paragraph 1.2, and that the acquisition of such real property by Lessor and
the obtaining of construction financing for the construction of the building to
be built thereon by Lessor on such terms and amounts as are acceptable to
Lessor, are conditions precedent to the further obligations of Lessor and Lessee
under this Lease. Lessor shall have the right to terminate this Lease, by
written notice to Lessee, should Lessor fail to close on its acquisition of the
real property and construction financing for the building to be built thereon
within one hundred twenty (120) days following full execution and delivery of
this Lease by both Lessor and Lessee, plus additional periods of delay due to
force majeure. In the event of any such termination, Lessor shall promptly
return to Lessee the Security Deposit paid upon execution and delivery of this
Lease by Lessee, and thereafter the parties shall be discharged from all
further rights and obligations under this Lease.

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, however, (including but not limited to the obligations to pay Real
Property Taxes and insurance premiums and to maintain the Premises) shall be in
effect during such period. Any such early possession shall not affect nor
advance the Expiration Date of the Original Term.

(C) 1990-American Industrial Real Estate Association          FORM 204N-R-12/91




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

4.   RENT.

     4.1 BASE RENT. Lessee shall cause payment of Base Rent and other rent or
charges, as the same may be adjusted from time to time, to be received by Lessor
in lawful money of the United States, without offset or deduction, on or before
the day on which it is due under the terms of this Lease. Base Rent and all
other rent and charges for any period during the term hereof which is for less
than one (1) full calendar month shall be prorated based upon the actual number
of days of the calendar month involved. Payment of Base Rent and other charges
shall be made to Lessor at its address stated herein or to such other persons or
at such other addresses as Lessor may from time to time designate in writing to
Lessee. On each 30-month anniversary of the Commencement Date, the Base Rent
shall be increased to an amount equal to the Base Rent then in effect multiplied
by 1.075.

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

6.   USE.

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

          (c)  Throughout the Lease Term, Lessee, at Lessee's sole cost and
expense, shall comply with, and shall not use the Premises in any way which
conflicts with, all Applicable Laws and Applicable Requirements (as hereinafter
defined). Lessee shall not place or permit to be placed any loads upon the
floors, walls or ceilings in excess of the maximum designed load specified by
Lessor or which might damage the Premises, or place or permit to be placed any
harmful liquids in the drainage systems, and Lessee shall not dump or store, or
permit to be dumped or stored, any inventory, waste materials, refuse or other
materials or allow any such materials to remain outside the Premises, except in
designated enclosed trash areas. Lessee, at its sole cost and expense, shall
procure, maintain and make available for Lessor's inspection throughout the
Lease Term, all governmental approvals, licenses and permits required for the
proper and lawful conduct of Lessee's Permitted Use of the Premises.

     6.2  HAZARDOUS SUBSTANCES.

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

          Prior to the execution of this Lease, Lessee shall complete, execute
and deliver to Lessor an Environmental Questionnaire and Disclosure Statement
(the "Environmental Questionnaire") in form required by Lessor, and Lessee shall
certify to Lessor all information contained in the Environmental Questionnaire
as true and correct to the best of Lessee's knowledge and belief. The completed
Environmental Questionnaire shall be deemed incorporated into this Lease for all
purposes, and Lessor shall be entitled to rely fully on the information
contained therein. On each anniversary of the Commencement Date (each such date
is hereinafter referred to as a "Disclosure Date"), until and including the
first Disclosure Date occurring after the expiration or sooner termination of
this Lease, Lessee shall disclose to Lessor in writing the names and amounts
of all Hazardous Substances, or any combination thereof, which were stored,
generated, used or disposed of on, under or about the Premises for the
twelve-month period prior to each Disclosure Date, and which Lessee intends to
store, generate, use or dispose of on, under or about the Premises through the
next Disclosure Date. At Lessor's option, Lessee's disclosure obligations
hereunder shall include a requirement that Lessee update, execute and deliver to
Lessor the Environmental Questionnaire, as the same may be modified by Lessor
from time to time.

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

          (c) INDEMNIFICATION. Lessee shall indemnify, protect, defend and hold
Lessor, its agents, employees, lenders and ground lessor, if any, and the
Premises, harmless from and against any and all loss of rents and/or damages,
liabilities, judgments, costs, claims, liens, expenses, penalties, permits and
attorney's and consultant's fees arising out of or involving any Hazardous
Substance or storage tank brought onto the Premises by or for Lessee or under
Lessee's control. Lessee's obligations under this Paragraph 6 shall include, but
not be limited to, the effects of any contamination or injury to person,
property or the environment created or suffered by Lessee, and the cost of
investigation (including consultant's and attorney's fees and testing), removal,
remediation, restoration and/or abatement thereof, or of any contamination
therein involved, and shall survive the expiration or earlier termination of
this Lease. No termination, cancellation or release agreement entered into by
Lessor and Lessee shall release Lessee from its obligations under this Lease
with respect to Hazardous Substances or storage tanks, unless specifically so
agreed by Lessor in writing at the time of such agreement.

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

     6.4 INSPECTION; COMPLIANCE. Lessor and Lessor's Lender(s) (as defined in
Paragraph 8.3(a)) shall have the right to enter the Premises at any time, upon
written notice to Lessee in the case of an emergency, and otherwise at
reasonable times, for the purpose of inspecting the condition of the Premises
and for verifying compliance by Lessee with this Lease and all Applicable Laws
(as defined in Paragraph 6.3), and to employ experts and/or consultants in
connection therewith and/or to advise Lessor with respect to Lessee's
activities, including but not limited to the installation, operation, use,

statute now or hereafter in effect to the extent it is inconsistent with the
terms of this Lease with respect to, or which affords Lessee the right to make

in Paragraph 7.4(a). Lessee shall not make any Alterations or Utility
Installations in, on, under or about the Premises without Lessor's prior written

non-structural Utility Installations to the interior of the Premises (excluding
the roof), as long as they are not visible from the outside, do not involve
puncturing, relocating or removing the roof or any existing walls, and the
cumulative cost thereof during the term of this Lease as extended does not
exceed $25,000.

          (b) CONSENT. Any Alterations or Utility Installations that Lessee
shall desire to make and which require the consent of the Lessor shall be
presented to Lessor in written form with proposed detailed plans. All consents
given by Lessor, whether by virtue of Paragraph 7.3(a) or by subsequent specific
consent, shall be deemed conditioned upon: (i) Lessee's acquiring all applicable
permits required by governmental authorities, (ii) the furnishing of copies of
such permits together with a copy of the plans and specifications for the

materialmen's lien against the Premises or any interest therein. Lessee shall
give Lessor not less than ten (10) days' notice prior to the commencement of any
work in, on or about the Premises, and Lessor shall have the right to post
notices of non-responsibility in or on the Premises as provided by law. If
Lessee shall, in good faith, contest the validity of any such lien, claim or
demand, then Lessee shall, at its sole expense defend and protect itself, Lessor
and the Premises against the same and shall pay and satisfy any such adverse
judgment that may be rendered thereon before the enforcement thereof against the
Lessor or the Premises. If Lessor shall require, Lessee shall furnish to Lessor
a surety bond satisfactory to Lessor in an amount equal to one and one-half
times the amount of such contested lien claim or demand indemnifying Lessor
against liability for the same, as required by law for the holding of the
Premises free from the effect of such lien or claim. In addition, Lessor may
require Lessee to pay Lessor's attorney's fees and costs in participating in
such action if Lessor shall decide it is to its best interest to do so.

     7.4 OWNERSHIP; REMOVAL; SURRENDER; AND RESTORATION.

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

          (b) REMOVAL. Lessor may require the removal at any time of all or any
part of any Lessee Owned Alterations or Utility Installations made without the
required consent of Lessor.

          (c) SURRENDER/RESTORATION. Lessee shall surrender the Premises by the
end of the last day of the lease term or any earlier termination date with all
of the improvements, parts and surfaces thereof clean and free of debris and in
good operating order, condition and state of repair, ordinary wear and tear
excepted. "ORDINARY WEAR AND TEAR" shall not include any damage or deterioration
that would have been prevented by good maintenance practice or by Lessee
performing all of its obligations under the Lease. Except as otherwise agreed or
specified in writing by Lessor, the Premises, as surrendered shall include the
Utility Installations. The obligation of Lessee shall include the repair of any
damage occasioned by the installation, maintenance or removal of Lessee's Trade
Fixtures, furnishings, equipment, and Alterations and/or Utility Installations,
as well as the removal of any storage tank installed by or for Lessee, and the
removal, replacement, or remediation of any soil, material or ground water
contaminated by Lessee, all as may then be required by Applicable Law and/or
good service practice. Lessees Trade Fixtures shall remain the property of
Lessee and shall be removed by Lessee subject to its obligation to repair and
restore the Premises per this Lease.

8. INSURANCE; INDEMNITY.

     8.1 PAYMENT FOR INSURANCE. Regardless of whether the Lessor or Lessee is
the Insuring Party, Lessee shall pay for all insurance required under this
Paragraph 8 except to the extent of the cost attributable to liability insurance
carried by Lessor in excess of $1,000,000 per occurrence. Premiums for policy
periods commencing prior to or extending beyond the Lease term shall be prorated
to correspond to the Lease term. Payment shall be made by Lessee to Lessor
within ten (10) days following receipt of an invoice for any amount due.

     8.2 LIABILITY INSURANCE.

          (a) CARRIED BY LESSEE. Lessee shall obtain and keep in force during
the term of this Lease 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, involving 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 "Additional Insured-Managers or Lessors of Premises"
Endorsement and contain the "Amendment of the Pollution Exclusion" 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 required by this Lease or as carried by
Lessee shall not, however, limit the liability of Lessee nor relieve Lessee of
any obligation hereunder. All insurance to be carried by Lessee shall be primary
to and not contributory with any similar insurance carried by Lessor, whose
insurance shall be considered excess insurance only.

          (b) CARRIED BY LESSOR. In the event Lessor is the Insuring party,
Lessor may also maintain liability insurance described in Paragraph 8.2(a),
above, in addition to, and not in lieu of, the insurance required to be
maintained by Lessee. Lessee shall not be named as an additional insured
therein.

  8.3 PROPERTY INSURANCE - BUILDING, IMPROVEMENTS AND RENTAL VALUE.

     (a) BUILDING AND IMPROVEMENTS. The Insuring Party shall obtain and keep in
force during the term of this Lease a policy or policies in the name of Lessor,
with loss payable to Lessor and to the holders of any mortgages, deeds of trust
or ground leases on the Premises ("LENDER(S)"), insuring loss or damage to the
Premises. The amount of such insurance shall be equal to the full replacement
cost of the Premises, as the same shall exist from time to time, or the amount
required by Lenders. If Lessor is the Insuring Party, however, Lessee Owned
Alterations and Utility Installations 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 any additional
costs resulting from debris removal and reasonable amounts of coverage for the
enforcement of any ordinance or law regulating the reconstruction or
replacement of any undamaged sections of the Premises required to be demolished
or removed by reason of the enforcement of any building, zoning, safety or land
use laws as the result of a covered cause of loss. Said policy or policies
shall also contain an agreed valuation provision in lieu of any coinsurance
clause, waiver of subrogation, and inflation guard protection causing an
increase in the annual property insurance coverage amount by a factor of not
less than the adjusted U.S. Department of Labor Consumer Price Index for All
Urban Consumers for the city nearest to where the Premises are located. If such
insurance coverage has a deductible clause, the deductible amount shall not
exceed $10,000 per occurrence, and Lessee shall be liable for such deductible
amount in the event of an Insured Loss, as defined in Paragraph 9.1(c).

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

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

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

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

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

  8.6 WAIVER OF SUBROGATION. Without affecting any other rights or remedies,
Lessee and Lessor ("WAIVING PARTY") each hereby release and relieve the other,
and waive their entire right to recover damages (whether in contract or in
tort) against the other, for loss of or damage to the Waiving Party's property
arising out of or incident to the perils required to be insured against under
Paragraph 8. The effect of such releases and waivers of the right to recover
damages shall not be limited by the amount of insurance carried or required, or
by any deductibles applicable thereto.

Notwithstanding the foregoing, it is agreed that (i) nothing contained herein
shall absolve Lessee of its obligations of maintenance and repair and payment
of insurance deductibles under this Lease, and (ii) in the event that any loss
is due to the act, omission or negligence or willful misconduct of Lessee or
any of its agents, employees, contractors or invitees, Lessee's liability
insurance shall be primary and shall cover all losses and damages prior to any
other insurance hereunder.

  8.7 INDEMNITY. Lessee shall indemnify, protect, defend and hold harmless the
Premises, Lessor and its agents. Lessor's master or ground lessor, partners and
Lenders, from and against any and all claims, loss of rents and/or damages,
costs, liens, judgments, penalties, permits, attorney's and consultant's fees,
expenses and/or liabilities arising out of, involving, or in dealing with, the
occupancy of the Premises by Lessee, the conduct of Lessee's business, any act,
omission or neglect of Lessee, its agents, contractors, employees or invitees,
and out of any Default or Breach by Lessee in the performance in a timely
manner of any obligation on Lessee's part to be performed under this Lease. The
foregoing shall include, but not be limited to, the defense or pursuit of any
claim or any action or proceeding involved therein, and whether or not (in the
case of claims made against Lessor) litigated and/or reduced to judgment, and
whether well founded nor not. In case any action or proceeding be brought
against Lessor by reason of any of the foregoing matters. Lessee upon notice
from Lessor shall defend the same at Lessee's expense by counsel reasonably
satisfactory to Lessor and Lessor shall cooperate with Lessee in such defense.
Lessor need not have first paid any such claim in order to be so indemnified.

  8.8 EXEMPTION OF LESSOR FROM LIABILITY. Except to the extent caused by the
negligence or willful misconduct of Lessor, 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, air conditioning or lighting fixtures or from any
other cause, whether the said injury or damage results from conditions arising
upon the Premises or upon other portions of the building of which the Premises
are a part, or from other sources or places, and regardless of whether the
cause of such damage or injury or the means of repairing the same is accessible
or not. Lessor shall not be liable for any damages arising from any act or
neglect of any other tenant of Lessor. Notwithstanding Lessor's negligence or
breach of this Lease, Lessor shall under no circumstances be liable for injury
to Lessee's business or for any loss of income or profit therefrom.

9. DAMAGE OR DESTRUCTION.

  9.1 LESSOR'S OBLIGATION TO REBUILD. If the Premises are damaged by fire or
other casualty ("Premises Partial Damage"), Lessee shall promptly give notice
thereof to Lessor, and Lessor shall thereafter repair the Premises as set forth
in Paragraph 9.4 unless Lessor has the right to terminate this Lease as provided
in Paragraph 9.2 and Lessor elects to so terminate. If the Premises are totally
destroyed other than by any act or omission of Lessee or Lessee's agents,
employees, contractors or invitees, this Lease shall automatically terminate as
of the date of such total destruction.

 9.2 LESSOR'S RIGHT TO TERMINATE. Lessor shall have the right to terminate this
Lease following a Premises Partial Damage if any of the following occurs: (1)
insurance proceeds (together with any additional amounts Lessee elects, at its
option, to contribute) are not available to Lessor to pay one hundred percent
(100%) of the cost to fully repair the Premises, excluding the deductible (for
which Lessee shall be responsible to pay); (ii) Lessor determines that the
Premises cannot, with reasonable diligence, be fully repaired by Lessor (or
cannot be safely repaired because of the presence of hazardous factors,
including, but not limited to, Hazardous Substances, earthquake faults,
radiation, chemical waste and other similar dangers) within one hundred eighty
(180) days after the date of such Premises Partial Damage; or (iii) a Default or
Breach by Tenant has occurred and is continuing at the time. If Lessor elects to
terminate this Lease pursuant to this Paragraph 9.2, Lessor shall give Lessee
written notice of its election to terminate within thirty (30) days after Lessor
has knowledge of such Premises Partial Damage, and this Lease shall terminate
thirty (30) days after the date of such notice. The determination in good faith
by Lessor of or relating to the estimated cost of repair of any damage,
replacement cost, the time period required for repair or the interference with
or suitability of the Premises for Lessee's use or occupancy, shall be
conclusive for purposes hereof.

  9.3 EFFECT OF TERMINATION. If this Lease is terminated pursuant to Paragraphs
9.1 or 9.2, Lessor shall, subject to the rights of any Lenders, be entitled to
receive and retain all insurance proceeds resulting from or attributable to such
damage or destruction, except for proceeds payable under policies obtained by
Lessee which specifically insure Lessee's  personal property and Trade Fixtures.
If Lessor does not exercise any right to terminate this Lease, this Lease will
continue in full force and effect, and Lessor shall, promptly following the
tenth (10th) day after the date of receipt of the amounts set forth in clause
(i) of Paragraph 9.2, commence the process of obtaining necessary permits and
approvals for the repair of the Premises, and shall commence such repair and
prosecute the same diligently to completion as soon thereafter as is
practicable. Lessee shall fully cooperate with Lessor in removing Lessee's
personal property, Trade Fixtures, and any debris from the Premises to
facilitate the making of such repairs.

  9.4 LIMITED OBLIGATION TO REPAIR. Lessor's obligation, should it elect or
be obligated to repair the Premises following a Premises Partial Damage, shall
be limited to the Improvements constructed by Lessor pursuant to Exhibit A, and
Lessee shall, at its expense, replace or fully repair all Lessee's personal
property, Trade Fixtures, Utility Installations and Lessee-Owned Alterations
installed by Lessee existing at the time of such damage. If the Premises are
to be repaired in accordance with the foregoing, Lessee shall make available to
Lessor any portion of insurance proceeds it receives which are allocable to any
Improvements installed by Lessor.

   9.5  DAMAGE NEAR END OF TERM. If at any time during the last six (6) months
of the term of this Lease there is damage for which the cost to repair exceeds
one (1) month's Base Rent, Lessor may, at Lessor's option, terminate this Lease
effective sixty (60) days following the date of occurrence of such damage by
giving written notice to Lessee of Lessor's election to do so within thirty (30)
days after the date of occurrence of such damage. Provided, however, if Lessee
at that time has an exercisable option to extend this Lease or to purchase the
Premises, then Lessee may preserve this Lease by, within twenty (20) days

said Exercise Period Lessor shall, to the extent otherwise required by this
Paragraph 9, at Lessor's expense repair such damage as soon as reasonably
possible and this Lease shall continue in full force and effect. If Lessee fails
to exercise such option during said Exercise Period, then Lessor may at Lessor's
option terminate this Lease as of the expiration of said sixty (60) day period
following the occurrence of such damage by giving written notice to Lessee of
Lessor's election to do so within ten (10) days after the expiration of the

any, payable by Lessee hereunder for the period during which such damage, its
repair or the restoration continues (not to exceed the period for which rental

proportion to the degree to which Lessee's use of the Premises is impaired.
Except for abatement of Base Rent, Real Property Taxes, insurance premiums, and
other charges, if any, as aforesaid, all other obligations of Lessee hereunder

under the provisions of this Paragraph 9 and shall not commence, in a
substantial and meaningful way, the repair or restoration of the Premises
within ninety (90) days after such obligation shall accrue. Lessee may, at any
time prior to the commencement of such repair or restoration, give written
notice to Lessor and to any Lenders of which Lessee has actual notice of

days following the giving of such notice. If Lessee gives such notice to Lessor
and such Lenders and such repair or restoration is not commenced within thirty
(30) days after receipt of such notice, this Lease shall terminate as of the
date specified in said notice. If Lessor or a Lender commences the repair or
restoration of the Premises within thirty (30) days after receipt of such
notice, this Lease shall continue in full force and effect. "COMMENCE" as used
in this Paragraph shall mean either the unconditional authorization of the

investigate and remediate such Hazardous Substance Condition, if required as
soon as reasonably possible at Lessor's expense, in which event this Lease
shall continue in full force and effect, give written notice to Lessee within

Hazardous Substance Condition of Lessor's desire to terminate this Lease as of
the date sixty (60) days following the giving of such notice.

the terms of this Lease.

   9.9  WAIVE STATUTES. Lessor and Lessee agree that the terms of this Lease
shall govern the effect of any damage to or destruction of the Premises with

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

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

  10.3  JOINT ASSESSMENT. If the Premises are not separately assessed, Lessee's

of the land and improvements included within the tax parcel assessed, such
proportion to be determined by Lessor from the respective valuations

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

     10.4  PERSONAL PROPERTY TAXES. Lessee shall pay prior to delinquency all
taxes assessed against and levied upon Lessee Owned Alterations, Utility
Installations, Trade Fixtures, furnishings, equipment and all personal property
of Lessee contained in the Premises or elsewhere. When possible, Lessee shall

to be assessed and billed separately from the real property of Lessor. If any of
Lessee's said personal property shall be assessed with Lessor's real property,
Lessee shall pay Lessor the taxes attributable to Lessee within ten (10) days
after receipt of a written statement setting forth the taxes applicable to
Lessee's property or, at Lessor's option, as provided in Paragraph 10.1(b).

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

12. ASSIGNMENT AND SUBLETTING.

     12.1 LESSOR'S CONSENT REQUIRED.

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

          (b)  Notwithstanding anything herein to the contrary, Lessee shall
have the right to assign this Lease or to sublet the Premises in whole or in
part to any entity which controls, is controlled by, or is under common control
with Lessee ("Affiliate"), provided that Lessee provides written notice to
Lessor of any such subletting or assignment and of the identity of such
assignee or sublessee and provided that the obligations of Lessee shall not be
diminished or effected in any manner by reason of such assignment or
subletting. In addition, a sale or transfer of any stock of Lessee shall not
constitute a transfer or assignment and shall not require the consent of Lessor
hereunder.

          (d) Where Lessor's consent is required under this Paragraph 12, an
assignment or subletting of Lessee's interest in this Lease without Lessor's
specific prior written consent shall, at Lessor's option, be a Default curable
after notice per Paragraph 13.1(c), or a noncurable Breach without the necessity
of any notice and grace period. If Lessor elects to treat such unconsented to
assignment or subletting as a noncurable Breach, Lessor shall have the right to
terminate this Lease.

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

     12.2 TERMS AND CONDITIONS APPLICABLE TO ASSIGNMENT AND SUBLETTING.

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

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

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

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

          (e) Each request for consent to an assignment or subletting shall be
in writing, accompanied by information relevant to Lessor's determination as to
the financial and operational responsibility and appropriateness of the proposed
assignee or sublessee, including but not limited to the intended use and/or
required modification of the Premises, if any, together with a non-refundable
deposit of $1,000 (which amount shall be reduced to $500 for any assignment or
sublease to an Affiliate), as reasonable consideration for Lessor's considering
and processing the request for consent. Lessee agrees to provide Lessor with
such other or additional information and/or documentation as may be reasonably
requested by Lessor.

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

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

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

          (i) Lessor shall, within thirty (30) days of receipt of written
notice of any proposed assignment of sublease and all information requested by
Lessor concerning the proposed assignee or sublessee, elect to take one of the
following actions:

                  (i) consent to such proposed assignment or sublease;

                  (ii) refuse to consent to such proposed assignment or
          sublease, which refusal shall be on reasonable grounds; or

                  (iii) if Lessee proposes to sublease all or part of the
          Premises for the entire remaining Lease term, Lessor may, at its
          option exercised by thirty (30) days notice to Lessee, elect to
          recapture such portion of the Premises as Lessee proposes to sublease
          and as of the thirtieth (30th) day after Lessor so notifies Lessee of
          its election to recapture, this Lease shall terminate as to the
          portion of the Premises recaptured and the Base Rent payable under
          this Lease shall be reduced in the same proportion that the floor area
          of that portion of the Premises so recaptured bears to the floor area
          of the Premises prior to such recapture.

          (j) Lessee agrees, by way of example and without limitation, that it
shall not be unreasonable for Lessor to withhold its consent to a proposed
assignment or subletting if any of the following situations exist or may exist:

                  (i) Lessor determines that the proposed assignee's or
          sublessee's use of the Premises presents an unacceptable risk, as
          determined by Lessor (and Lessor may require such assignee or
          sublessee to complete the Environmental Questionnaire in the manner
          described in Paragraph 6.2 prior to making such determination), or
          conflicts with any use or other provision under this Lease;

                  (ii) Lessor determines that the proposed assignee or
          sublessee is not as financially responsible as Lessee as of the date
          of Lessee's request for consent or as of the effective date of such
          assignment or subletting;

                  (iii) Lessor determines that the proposed assignee or
          sublessee lacks sufficient business reputation or experience to
          conduct on the Premises a business of a type and quality equal to that
          conducted by Lessee;


                  (iv) Lessor determines that the proposed assignment or
          subletting would breach a covenant, condition or restriction in some
          other lease, financing agreement or other agreement relating to the
          Industrial Center, the Building, the Premises or this Lease;

                  (v) Lessor determines that the proposed assignee or sublessee
          (A) has been required by any prior landlord, lender or governmental
          authority to take remedial action in connection with Hazardous
          Substances contaminating a property if such contamination resulted
          from the proposed assignee's or sublessee's actions or use of the
          property in question, or (B) is subject to any enforcement order
          issued by any governmental authority in connection with the use,
          disposal or storage of a Hazardous Substances; or

                  (vi) A Default or Breach by Lessee has occurred and is
          continuing at the time of Lessee's request for Lessor's consent, or as
          of the effective date of such assignment or subletting.

          Lessee acknowledges that if Lessee has any exterior sign rights under
this Lease, such rights are personal to Lessee and may not be assigned or
transferred to any assignee of this Lease or sublessee of the Premises without
Lessor's prior written consent, which consent may be withheld in Lessor's sole
and absolute discretion.

          (k) Lessee agrees that fifty percent (50%) of any amounts paid by the
assignee or sublessee, however described, in excess of (i) the Base Rent
payable by Lessee hereunder (or, in the case of sublease of a portion of the
Premises, in excess of the Base Rent reasonably allocable to such portion),
plus (ii) Lessee's direct out-of-pocket costs which Lessee certifies to Lessor
have been paid to provide occupancy related services to such assignee or
sublessee of a nature commonly provided by landlords of similar space, shall be
the property of Lessor and such amounts shall be payable directly to Lessor by
the assignee or sublessee. At Lessor's request, a written agreement shall be
entered into by and among Lessee, Lessor and the proposed assignee or sublessee
confirming the requirements hereof.

     12.3 ADDITIONAL TERMS AND CONDITIONS APPLICABLE TO SUBLETTING. The
following terms and conditions shall apply to any subletting by Lessee of all or
any part of the Premises and shall be deemed included in all subleases under
this Lease whether or not expressly incorporated therein:

          (a) Lessee hereby assigns and transfers to Lessor all of Lessee's
interest in all rentals and income arising from any sublease of all or a portion
of the Premises heretofore or hereafter made by Lessee, and Lessor may collect
such rent and income and apply same toward Lessee's obligations under this
Lease. Lessor shall not, by reason of this or any other assignment of such
sublease to Lessor, nor by reason of the collection of the rents from a
sublessee, be deemed liable to the sublessee for any failure of Lessee to
perform and comply with any of Lessee's obligations to such sublessee under such
sublease. Lessee hereby irrevocably authorizes and directs any such sublessee,
upon receipt of a written notice from Lessor, to pay to Lessor the rents and
other charges due and to become due under the sublease. Sublessee shall rely
upon any such statement and request from Lessor and shall pay such rents and
other charges to Lessor notwithstanding any notice from or claim from Lessee to
the contrary. Lessee shall have no right or claim against said sublessee, for
any such rents and other charges so paid by said sublessee to Lessor.

          (b) In the event of a Breach by Lessee in the performance of its
obligations under this Lease, Lessor, at its option and without any obligation
to do so, may require any sublessee to attorn to Lessor, in which event Lessor
shall undertake the obligations of the sublessor under such sublease from the
time of the exercise of said option to the expiration of such sublease,
provided, however, Lessor shall not be liable for any prepaid rents or security
deposit paid by such sublessee to such sublessor or for any other prior Defaults
or Breaches of such sublessor under such sublease.

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

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

          (e) Lessor shall have the right, but not the obligation, to 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.

13.  DEFAULT; BREACH; REMEDIES.

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




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

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

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

          (c) Except as expressly otherwise provided in this Lease, the failure
by Lessee to provide Lessor with reasonable written evidence (in duly executed
original form, if applicable) of (i) compliance with Applicable Law per
Paragraph 6.3, (ii) the inspection, maintenance and service contracts required
under Paragraph 7.1(b), (iii) the recission of an unauthorized assignment or
subletting per Paragraph 12.1(b), (iv) a Tenancy Statement per Paragraphs 16 or
37, (v) the subordination or non-subordination of this Lease per Paragraph 30,
(vi) the guaranty of the performance of Lessee's obligations under this Lease if
required under Paragraphs 1.11 and 37, (vii) the execution of any document
requested under Paragraph 42 (easements), or (viii) any other documentation or
information which Lessor may reasonably require of Lessee under the terms of
this Lease, where any such failure continues for a period of thirty (30) days
following written notice by or on behalf of Lessor to Lessee.

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

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

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

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

Any written notice given under this Paragraph 13.1 shall be in lieu of, and not
in addition to, the notice requirements of California CCP Section 1161 et. seq.

     13.2 REMEDIES. If Lessee fails to perform any affirmative duty or
obligation of Lessee under this Lease, within ten (10) days after written notice
to Lessee (or in case of an emergency, without notice), Lessor may at its option
(but without obligation to do so), perform such duty or obligation on Lessee's
behalf including but not limited to the obtaining of reasonably required bonds,
insurance policies, or governmental licenses, permits or approvals. The costs
and expenses of any such performance by Lessor shall be due and payable by
Lessee to Lessor upon invoice therefor. If any check given to Lessor by Lessee
shall not be honored by the bank upon which it is drawn, Lessor, at its option,
may require all future payments to be made under this Lease by Lessee to be made
only by cashier's check in the event of a Breach of this Lease by Lessee, as
defined in Paragraph 13.1, with or without further notice or demand, and without
limiting Lessor in the exercise of any right or remedy which Lessor may have by
reason of such Breach, Lessor may:

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

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

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

          (d) The expiration or termination of this Lease and/or the termination
of Lessee's right to possession shall not relieve Lessee from liability under
any indemnity provisions of this Lease as to matters occurring or accruing
during the term hereof or by reason of Lessee's occupancy of the Premises.

     13.3 INTENTIONALLY OMITTED

     13.4 LATE CHARGES. Lessee hereby acknowledges that late payment by Lessee
to Lessor of rent and other sums due hereunder will cause Lessor to incur costs
not contemplated by this Lease, the exact amount of which will be extremely
difficult to ascertain. Such costs include, but are not limited to, processing
and accounting charges, and late charges which may be imposed upon Lessor by the
terms of any ground lease, mortgage or trust deed covering the Premises.
Accordingly, if any installment of rent or any other sum due from Lessee shall
not be received by Lessor or Lessor's designee within five (5) days after such
amount shall be due, then, without any requirement for notice to Lessee, Lessee
shall pay to Lessor a late charge equal to five percent (5%) of such overdue
amount. The parties hereby agree that such late charge represents a fair and
reasonable estimate of the costs Lessor will incur by reason of late payment by
Lessee. Acceptance of such late charge by Lessor shall in no event constitute a
waiver of Lessee's Default or Breach with respect to such overdue amount, nor
prevent Lessor from exercising any of the other rights and remedies granted
hereunder.

     13.5 BREACH BY LESSOR. Lessor shall not be deemed in breach of this Lease
unless Lessor fails within a reasonable time to perform an obligation required
to be performed by Lessor. For purposes of this Paragraph 13.5, a reasonable
time shall in no event be less than thirty (30) days after receipt by Lessor,
and by the holders of any ground lease, mortgage or deed of trust covering the
Premises whose name and address shall have been furnished Lessee in writing for
such purpose, of written notice specifying wherein such obligation of Lessor has
not been performed; provided, however, that if the nature of Lessor's obligation
is such that more than thirty (30) days after such notice are reasonably
required for its performance, then Lessor shall not be in breach of this Lease
if performance is commenced within such thirty (30) day period and thereafter
diligently pursued to completion.

     13.6 LIMITATION OF LESSOR'S LIABILITY. The obligations of Lessor do not
constitute the personal obligations of the individual partners, trustees,
directors, officers or shareholders of Lessor or its constituent partners. If
Lessor shall fail to perform any covenant, term, or condition of this Lease
upon Lessor's part to be performed, Lessee shall be required to deliver to
Lessor written notice of the same. If, as a consequence of such default, Lessee
shall recover a money judgment against Lessor, such judgment shall be satisfied
only out of the proceeds of sale received upon execution of such judgment and
levied thereon against the right, title and interest of Lessor in the Building
and out of rent or other income from such property receivable by Lessor or out
of consideration received by Lessor from the sale or other disposition of all
or any part of Lessor's right, title or interest in the Building, and no action
for any deficiency may be sought or obtained by Lessee.

    13.7 LIMITATION OF ACTIONS AGAINST LESSOR. Any claim, demand or right of any
kind by Lessee which is based upon or arises in connection with this Lease
shall be barred unless Lessee commences an action thereon within the earlier of
(i) six (6) months after the date that Lessee discovers the act, omission,
event or default upon which the claim, demand or right arises, or (ii) twelve
(12) months after the date that the act, omission, event or default upon which
the claim, demand or right arises, has occurred.

14. CONDEMNATION. If the Premises or any portion thereof are taken under the
power of eminent domain or sold under the threat of the exercise of said power
(all of which are herein called "CONDEMNATION"), this Lease shall terminate as
to the part so taken as of the date the condemning authority takes

                                     PAGE 7


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

15. BROKER'S FEE.

     15.1 TO 15.4 INTENTIONALLY OMITTED

     15.5 Lessee and Lessor each represent and warrant to the other that it has
had no dealings with any person, firm, broker or finder (other than the Brokers,
if any named in Paragraph 1.10) in connection with the negotiation of this Lease
and/or the consummation of the transaction contemplated hereby, and that no
broker or other person, firm or entity other than said named Brokers is entitled
to any commission or finder's fee in connection with said transaction. Lessee
and Lessor do each hereby agree to indemnify, protect, defend and hold the other
harmless from and against liability for compensation or charges which may be
claimed by any 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.

     15.6 INTENTIONALLY OMITTED

16. TENANCY STATEMENT.

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

     16.2 Within ten (10) days after written request from Lessor, Lessee and all
Guarantors of Lessee's performance hereunder shall deliver to Lessor and to any
potential lender or purchaser designated by Lessor such financial statements of
Lessee and such Guarantors as may be reasonably required, including but not
limited to Lessee's financial statements for the past three (3) years. All such
financial statements shall be received by Lessor and such lender or purchaser in
confidence and shall be used only for the purposes herein set forth.

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

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


19. INTEREST ON PAST-DUE OBLIGATIONS. Any monetary payment due Lessor hereunder,
other than late charges, not received by Lessor within thirty (30) days
following the date on which it was due, shall bear interest from the
thirty-first (31st) day after it was due at the rate of 10% per annum, but not
exceeding the maximum rate allowed by law, in addition to the late charge
provided for in Paragraph 13.4.

20. TIME OF ESSENCE. Time is of the essence with respect to the performance of
all obligations to be performed or observed by the Parties under this Lease.

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

22. NO PRIOR OR OTHER AGREEMENTS. 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 that it has made, and is relying solely upon, its
own investigation as to the nature, quality, character and financial
responsibility of the other Party to this Lease and as to the nature, quality
and character of the Premises.

23. NOTICES.

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

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

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

26. RECORDING. Lessee shall not record this Lease or any short form memorandum
thereof.

26. NO RIGHT TO HOLDOVER. Lessee has no right to retain possession of the
Premises or any part thereof beyond the expiration or earlier termination of
this Lease. Lessee indemnifies Lessor from all loss or liability arising from
any holding over by Lessee without Lessor's express written consent or failure
of Lessee to surrender the Premises in accordance with Paragraph 7.4(c),
including without limitation claims made by succeeding lessees or losses due to
lost opportunities to lease to succeeding lessees.


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

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

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

30. SUBORDINATION; ATTORNMENT; NON-DISTURBANCE.

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

     30.2 ATTORNMENT. Subject to the non-disturbance provisions of Paragraph
30.3, Lessee agrees to attorn to a Lender or any other party who acquires
ownership of the Premises by reason of a foreclosure of a Security Device, and
that in the event of such foreclosure, such new owner shall not: (i) be liable
for any act or omission of any prior lessor or with respect to events occurring
prior to acquisition of ownership, (ii) be subject to any offsets or defenses
which Lessee might have against any prior lessor, or (iii) be bound by
prepayment of more than one (1) month's rent.

     30.3 NON-DISTURBANCE. With respect to Security Devices entered into by
Lessor after the execution of this Lease, Lessee's possession and this Lease,
including any options to extend the term hereof, will not be disturbed so long
as Lessee is not in Breach hereof and attorns to the record owner of the
Premises.

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

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

32. LESSOR'S ACCESS; SHOWING PREMISES; REPAIRS. Lessor and Lessor's agents shall
have the right to enter the Premises at any time, in the case of an emergency,
and otherwise at reasonable times for the purpose of making such alterations,
repairs, improvements or additions to the Premises or to the building of which
they are a part, as Lessor may reasonably deem necessary. All such activities of
Lessor shall be without abatement of rent or liability to Lessee.

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

34. SIGNS. Subject to compliance with all Applicable Law and reasonable approval
by Lessor, Lessee shall be entitled to all signage rights on the Premises. The
installation of any sign on the Premises by or for Lessee shall be subject to
the provisions of Paragraph 7 (Maintenance, Repairs, Utility Installations,
Trade Fixtures and Alterations). Unless otherwise expressly agreed herein,
Lessor reserves all rights to the use of the roof and the right to install, and
all revenues from the installation of, such advertising signs on the Premises,
including the roof, as do not unreasonably interfere with the conduct of
Lessee's business.

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

36. CONSENTS.

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

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

37. GUARANTOR.

    37.1 & 37.2 INTENTIONALLY OMITTED

38. QUIET POSSESSION. Upon payment by Lessee of the rent for the Premises and
the observance and performance of all of the covenants, conditions and
provisions on Lessee's part to be observed and performed under this Lease,
Lessee shall have quiet possession of the Premises as against Lessor and any
parties claiming through Lessor for the entire term hereof subject to all of the
provisions of this Lease.


39. OPTIONS.

    39.1 Definition. As used in this Paragraph 39 the word "Option" has the
following meaning: (a) the right to extend the term of this Lease or to review
this Lease

<PAGE>
39.4 EFFECT OF DEFAULT ON OPTIONS.

     (a) Lessee shall have no right to exercise an Option, notwithstanding any
provision in the grant of Option to the contrary: (1) during the period
commencing with the giving of any notice of Default under Paragraph 13.1 and
continuing until the noticed Default is cured, or (ii) during the period of time
any monetary obligation due Lessor from Lessee is unpaid (without regard to
whether notice thereof is given Lessee), or (iii) during the time Lessee is in
Breach of this Lease, or (iv) in the event that Lessor has given to Lessee three
(3) or more notices of Default under Paragraph 13.1, whether or not the Defaults
are cured, during the twelve (12) month period immediately preceding the
exercise of the Option.

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

     (c) All rights of Lessee under the provisions of 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 during the term of this
Lease, (i) Lessee fails to pay to Lessor a monetary obligation of Lessee for a
period of thirty (30) days after such obligation becomes due (without any
necessity of Lessor to give notice thereof to Lessee), or (ii) Lessor gives to
Lessee three (3) or more notices of Default under Paragraph 13.1 during any
twelve (12) month period, whether or not the Defaults are cured, or (iii) if
Lessee commits a Breach of this Lease.

40. INTENTIONALLY OMITTED.

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

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

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

44. AUTHORITY. If either Party hereto is a corporation, trust, or general or
limited partnership, each individual executing this Lease on behalf of such
entity represents and warrants that he or she is duly authorized to execute and
deliver this Lease on its behalf. If Lessee is a corporation, trust or
partnership, Lessee shall, within thirty (30) days after request by Lessor,
deliver to Lessor evidence satisfactory to Lessor of such authority.

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

46. OFFER. Preparation of this Lease by Lessor or Lessor's agent and submission
of same to Lessee shall not be deemed an offer to lease to Lessee. This Lease is
not intended to be binding until executed by all Parties hereto.

47. AMENDMENTS. This Lease may be modified only in writing, signed by the
Parties in interest at the time of the modification. The parties shall amend
this Lease from time to time to reflect any adjustments that are made to the
Base Rent or other rent payable under this Lease. As long as they do not
materially change Lessee's obligations hereunder, Lessee agrees to make such
reasonable non-monetary modifications to this Lease as may be reasonably
required by an institutional, insurance company, or pension plan Lender in
connection with the obtaining of normal financing or refinancing of the property
of which the Premises are a part.

48. MULTIPLE PARTIES. Except as otherwise expressly provided herein, if more
than one person or entity is named herein as either Lessor or Lessee, the
obligations of such Multiple Parties shall be the joint and several
responsibility of all persons or entities named herein as such Lessor or Lessee.

LESSOR AND LESSEE HAVE CAREFULLY READ AND REVIEWED THIS LEASE AND EACH TERM AND
PROVISION CONTAINED HEREIN, AND BY THE EXECUTION OF THIS LEASE SHOW THEIR
INFORMED AND VOLUNTARY CONSENT THERETO. THE PARTIES HEREBY AGREE THAT, AT THE
TIME THIS LEASE IS EXECUTED, THE TERMS OF THIS LEASE ARE COMMERCIALLY REASONABLE
AND EFFECTUATE THE INTENT AND PURPOSE OF LESSOR AND LESSEE WITH RESPECT TO THE
PREMISES.

      IF THIS LEASE HAS BEEN FILLED IN, IT HAS BEEN PREPARED FOR
      SUBMISSION TO YOUR ATTORNEY FOR HIS APPROVAL. FURTHER, EXPERTS
      SHOULD BE CONSULTED TO EVALUATE THE CONDITION OF THE PROPERTY AS
      TO THE POSSIBLE PRESENCE OF ASBESTOS, STORAGE TANKS OR HAZARDOUS
      SUBSTANCES. NO REPRESENTATION OR RECOMMENDATION IS MADE BY THE
      AMERICAN INDUSTRIAL REAL ESTATE ASSOCIATION OR BY THE REAL
      ESTATE BROKER(S) OR THEIR AGENTS OR EMPLOYEES AS TO THE LEGAL
      SUFFICIENCY, LEGAL EFFECT, OR TAX CONSEQUENCES OF THIS LEASE OR
      THE TRANSACTION TO WHICH IT RELATES; THE PARTIES SHALL RELY
      SOLELY UPON THE ADVICE OF THEIR OWN COUNSEL AS TO THE LEGAL AND
      TAX CONSEQUENCES OF THIS LEASE. IF THE SUBJECT PROPERTY IS

The parties hereto have executed this Lease at the place on the dates specified

                                    ADDENDUM

     THIS ADDENDUM is hereby attached to and made a part of that certain
Standard Industrial/Commercial Single-Tenant Lease--Net dated October 10, 2001
by and between RESEARCH VENTURE, LLC, a California limited liability company, as
"Lessor" and LITRONIC INC., a Delaware corporation, as "Lessee", for the
Premises located in the City of Irvine, Orange County, California as more
particularly described in said Lease.

     Unless otherwise defined herein, capitalized terms used in this Addendum
shall have the same definitions as set forth in the Lease. The provisions of
this Addendum shall supersede any inconsistent or conflicting provisions of the
Lease.

INSERT 1:

     2.6  LESSEE'S ACKNOWLEDGEMENT. Lessee acknowledges that as of the execution
of the Commencement Date it will have had an adequate opportunity to inspect the
Premises and to investigate its physical characteristics and conditions. Except
as expressly provided in Section 2.2 above, as of the execution of the
Commencement Date, Lessee shall be deemed to have waived any and all objections
to the physical characteristics and conditions of the Premises which would be
disclosed by a reasonable and diligent inspection. Lessee acknowledges that,
except as specifically provided in this Lease, neither Lessor nor any of its
employees, agents or representatives has made any representations, warranties or
agreements to or with Lessee on behalf of Lessor as to any matters concerning
the Premises, the use thereof, or the suitability of Lessee's intended use of
the Premises, and that Lessee accepts the Premises in their "AS-IS" condition.
Without limiting the generality of the foregoing, Lessee understands and agrees
that it leases the Premises without any representations or warranties by Lessor,
or by any official, employee or agent of Lessor, regarding the existence, use,
generation, manufacture, storage, transportation, release or disposal of
Hazardous Substances and/or oil wells and/or underground storage tanks and/or
pipelines on, under or about the Premises, or regarding whether the Premises is
or may be in violation of any federal, state or local law, ordinance or
regulation relating to Hazardous Substances and/or oil wells and/or underground
storage tanks and/or pipelines on, under or about the Premises, including
without limitation, soil and ground water conditions. Lessee acknowledges and
understands that it must perform its own "due diligence" with respect to all
environmental matters relating to the Premises, inclusive of any environmental
audits or assessments, and that Lessee is not relying on any environmental
audits or assessments performed by or on behalf of Lessor.

     2.7  PURCHASE AND FINANCING CONTINGENCY. It is understood and agreed that
as of the date of this Lease, Lessor does not own the real property described in
Paragraph 1.2, and that the acquisition of such real property by Lessor and the
obtaining of construction financing for the construction of the building to be
built thereon by Lessor on such terms and amounts as are acceptable to Lessor,
are conditions precedent to the further obligations of Lessor and Lessee under
this Lease. Lessor shall have the right to terminate this Lease, by written
notice to Lessee, should Lessor fail to close on its acquisition of the real
property and construction financing for the building to be built thereon within
one hundred twenty (120) days following full execution and delivery of this
Lease by both Lessor and Lessee, plus additional periods of delay due to force
majeure. In the event of any such termination, Lessor shall promptly return to
Lessee the Security Deposit paid upon execution and delivery of this Lease by
Lessee, and thereafter the parties shall be discharged from all further rights
and obligations under this Lease.

INSERT 2:

     (c)  Throughout the Lease Term, Lessee, at Lessee's sole cost and expense,
shall comply with, and shall not use the Premises in any way which conflicts
with, all Applicable Laws and Applicable Requirements (as hereinafter defined).
Lessee shall not place or permit to be placed any loads upon the floors, walls
or ceilings in excess of the maximum designed load specified by Lessor or which
might damage the Premises, or place or permit to be placed any harmful liquids
in the drainage systems, and Lessee shall not dump or store, or permit to be
dumped or stored, any inventory, waste materials, refuse or other materials or
allow any such materials to remain outside the Premises, except in designated
enclosed trash areas. Lessee, at its sole cost and expense, shall procure,
maintain and make available for Lessor's inspection throughout the Lease Term,
all governmental approvals, licenses and permits required for the proper and
lawful conduct of Lessee's Permitted Use of the Premises.

INSERT 3:

     Prior to the execution of this Lease, Lessee shall complete, execute and
deliver to Lessor an Environmental Questionnaire and Disclosure Statement (the
"Environmental Questionnaire") in form required by Lessor, and Lessee shall
certify to Lessor all information contained in the Environmental Questionnaire
as true and correct to the best of Lessee's knowledge and belief. The completed
Environmental Questionnaire shall be deemed incorporated into this Lease for all
purposes, and Lessor shall be entitled to rely fully on the information
contained therein. On each anniversary of the Commencement Date (each such date
is hereinafter referred to as a "Disclosure Date"), until and including the
first Disclosure Date occurring after the expiration or sooner termination of
this Lease, Lessee shall disclose to Lessor in writing the names and amounts of
all Hazardous Substances, or any combination thereof, which were stored,
generated, used or disposed of on, under or about the Premises for the
twelve-month period prior to each Disclosure Date, and which Lessee intends to
store, generate, use or dispose of on, under or about the Premises through the
next Disclosure Date. At Lessor's option, Lessee's disclosure obligations
hereunder shall include a requirement that Lessee update, execute and deliver to
Lessor the Environmental Questionnaire, as the same may be modified by Lessor
from time to time.

                                   EXHIBIT A
                                  WORK LETTER

     This Exhibit is attached to and made a part of that certain Standard
Industrial/Commercial Single Tenant Lease-Net dated October 10, 2001, by and
between RESEARCH VENTURE, LLC, a California limited liability company, as
"Lessor", and LITRONIC INC., a Delaware corporation, as "Lessee", for the
Premises located in the City of Irvine, Orange County, California, as more
particularly described in said Lease.

1.   APPLICATION OF EXHIBIT

     Capitalized terms used and not otherwise defined herein shall have the same
definitions as set forth in the Lease. The provisions of this Work Letter shall
apply to the planning and completion of the building, all tenant improvements
therein and all hardscape improvements to the Premises (hereafter collectively
the "Improvements"), as more fully set forth herein. It is understood and agreed
that the Improvements shall at all times belong to and be the property of
Lessor.

2.   LESSOR AM LESSEE PRE-CONSTRUCTION OBLIGATIONS

     (a)  PRELIMINARY PLANS. Attached to this Work Letter as Schedule I are
preliminary site plans and building specifications for the shell building
portion of the Improvements (the "Preliminary Plans"). Lessee shall coordinate
and cooperate with Lessor and Lessor's architect for the preparation, within
thirty (30) days after full execution of this Lease by both Lessor and Lessee,
of interior space plans for the tenant improvement portion of the Improvements,
which shall include, without limitation, sketches and/or drawings showing
locations of doors, partitioning, electrical fixtures, outlets and switches,
plumbing fixtures, floor loads and other requirements. Lessor and Lessor's
architect shall be entitled, in all respects, to rely upon all information
supplied by Lessee regarding such interior space plans and Lessee's
requirements.

     (b)  WORKING DRAWINGS. Within ninety (90) days following full execution of
this Lease by both Lessor and Lessee, Lessor's architect shall prepare working
drawings (the "Working Drawings") for the Improvements based upon the
Preliminary Plans and the aforesaid interior space plans. The Working Drawings
shall include architectural, structural, mechanical, plumbing and electrical
construction drawings for the building and tenant improvements, and landscape
drawings for the outside areas of the Premises, based on the Preliminary Plans
and the aforesaid interior space plans. Notwithstanding the Preliminary Plans
and the aforesaid interior space plans, in all cases the Working Drawings (i)
shall be subject to Lessor's final approval, which approval shall not be
unreasonably withheld, (ii) shall not be in conflict with building codes for the
City of Irvine or with insurance requirements for a fire resistive Class A
building, (iii) shall be in a form satisfactory to appropriate governmental
authorities responsible for issuing permits and licenses required for
construction, (iv) shall be in form and content satisfactory to The Irvine
Company pursuant to its approval rights under recorded covenants and
restrictions encumbering the real property, and (v) shall be in a form
satisfactory to any Lender.

     (c)  APPROVAL OF WORKING DRAWINGS. Lessor or Lessor's architect shall
submit the Working Drawings to Lessee for Lessee's review, and Lessee shall
notify Lessor and Lessor's architect within ten (10) business days after
delivery thereof of any requested revisions. Any requested revisions shall be
reasonable in nature, must be in writing, and must indicate in detail those
grounds upon which the revisions are based. Unless Lessor receives any requested
revisions within such ten (10) business day period, Lessee's approval of the
Working Drawings shall be conclusively deemed to have been given. Within ten
(10) business days after receipt of Lessee's notice, Lessor's architect shall
make all approved revisions to the Working Drawings and submit two (2) copies
thereof to Lessee for its final review and approval, which approval shall be
given within five (5) business days thereafter. Concurrently with the above
review and approval process, Lessor may submit all plans and specifications to
the City of Irvine, The Irvine Company, and other applicable agencies in an
attempt to expedite approvals and issuance of all necessary permits and licenses
to construct the Improvements as shown on the Working Drawings.

     (d)  SCHEDULE OF CRITICAL DATES. Set forth below is a schedule of certain
critical dates relating to Lessor's and Lessee's respective obligations for the
design of the Improvements. Such dates and the respective obligations of Lessor
and Lessee are more fully described elsewhere in this Work Letter. The purpose
of the following schedule is to provide a reference for Lessor and Lessee and to
make certain the Final Approval Date occurs as set forth herein. Following the
Final Approval Date, Lessee shall be deemed to have released Lessor to commence
construction of the Improvements as set forth in Section 4 below.

                             OPTION TO EXTEND TERM
                         (FAIR MARKET VALUE ADJUSTMENT)

     This Exhibit is attached to and made a part of that certain Standard
Industrial/Commercial Single Tenant Lease-Net dated October 10, 2001, by and
between RESEARCH VENTURE, LLC, a California limited liability company, as
"Lessor", and LITRONIC INC., a Delaware corporation, as "Lessee", for the
Premises located in the City of Irvine, Orange County, California, as more
particularly described in said Lease.

The capitalized terms used and not otherwise defined herein shall have the same
definitions as set forth in the Lease. The provisions of this Exhibit shall
supersede any inconsistent or conflicting provisions of the Lease.

     A.   OPTION TO EXTEND TERM.

          Lessor hereby grants to Lessee one (1) option (the "Option") to extend
the Original Term of the Lease for an additional consecutive term of five (5)
years and zero (0) months (the "Extension"), on the same terms and conditions as
set forth in the Lease, except the Base Rent shall be the amount determined as
set forth below. The Option shall be exercised only by written notice delivered
to Lessor at least one hundred eighty (180) days before the expiration of the
Original Term of the Lease. If Lessee fails to deliver to Lessor written notice
of the exercise of the option within the time period prescribed above, such
Option shall lapse, and there shall be no further right to extend the term of
the Lease. Lessee's rights in and to the Option shall otherwise be subject to,
governed by and conditioned upon the terms and provisions set forth in Paragraph
39 of the Lease, each and all of which are incorporated herein by this reference
as though set forth in full.

     B.   CALCULATION OF BASE RENT.

          The Base Rent during the Extension shall be increased, as of the
commencement of the Extension (the "Rental Adjustment Date") to the greater of
(i) an amount equal to the Base Rent in effect immediately prior to the Rental
Adjustment Date multiplied by 1.06, or (ii) one hundred percent (100%) of the
"Fair Market Value" of the Premises, determined in the following manner: Not
later than one hundred (100) days prior to the Rental Adjustment Date, Lessor
and Lessee shall meet in an effort to negotiate, in good faith, the Fair Market
Value of the Premises as of the Rental Adjustment Date. If Lessor and Lessee
have not agreed upon the Fair Market Value of the Premises at least ninety (90)
days prior to the Rental Adjustment Date, the Fair Market Value shall be
determined by the following appraisal method:

               (1)  If Lessor and Lessee are not able to agree upon the Fair
     Market Value of the Premises within the time period described above, then
     Lessor and Lessee shall attempt to agree in good faith upon a single
     appraiser not later than seventy-five (75) days prior to the Rental
     Adjustment Date. If Lessor and Lessee are unable to agree upon a single
     appraiser within such time period, then Lessor and Lessee shall each
     appoint one appraiser not later than sixty-five (65) days prior to the
     Rental Adjustment Date, and Lessor and Lessee shall each give written
     notice to the other of such appointment at the time of such appointment.
     Within ten (10) days thereafter, the two appointed appraisers shall appoint
     a third appraiser. If either Lessor or Lessee fails to appoint its
     appraiser and to give written notice thereof to the other party within the
     prescribed time period, the single appraiser appointed shall determine the
     Fair Market Value of the Premises. If both parties fail to appoint
     appraisers within the prescribed time periods, then the first appraiser
     thereafter selected by a party (such selection to be by written notice
     thereof to such appraiser and the other party) shall determine the Fair
     Market Value of the Premises. Each party shall bear the cost of its own
     appraiser and the parties shall share equally the cost of the single or
     third appraiser if applicable. All appraisers shall have at least five (5)
     years' experience in the appraisal of commercial/industrial real property
     in the area in which the Premises are located and shall be members of
     professional organizations such as MAI or its equivalent.

               (2)  For the purposes of such appraisal, the term "Fair Market
     Value" shall mean the price that a ready and willing tenant would pay, as
     of the Rental Adjustment Date, as monthly rent, to a ready and willing
     landlord of property comparable to the Premises if such property were
     exposed for lease on the open market for a reasonable period of time and
     taking into account all of the purposes for which such property may be
     used. If a single appraiser is chosen, then such appraiser shall determine
     the Fair Market Value of the Premises. Otherwise, the Fair Market Value of
     the Premises shall be the arithmetic average of the two (2) of the three
     (3) appraisals which are closest in amount, and the third appraisal shall
     be disregarded. Lessor and Lessee shall instruct the appraiser(s) to
     complete their determination of the Fair Market Value not later than thirty
     (30) days prior to the Rental Adjustment Date. If the Fair Market Value is
     not determined prior to the Rental Adjustment Date, then Lessee shall pay
     to Lessor the Base Rent applicable to the Premises as determined under
     clause (i) of this Section B until the Fair Market Value is determined.
     When the Fair Market Value of the Premises is determined, Lessor shall
     deliver notice thereof to Lessee, and Lessee shall pay to Lessor, within
     ten (10) days after receipt of such notice, the difference between the Base
     Rent actually paid by Lessee to Lessor for the period after the Rental
     Adjustment Date and the new Base Rent determined hereunder effective as of
     the Rental Adjustment Date, to the extent applicable.

Throughout the term of the Extension, the Base Rent shall be further increased
on the 30-month anniversary of the Rental Adjustment Date to an amount equal to
the Base Rent then in effect multiplied by 1.075.
