                             June 30, 1996 and 1995


1. BASIS OF PRESENTATION

These unaudited financial statements have been prepared in accordance with the
instructions for Form 10-Q and therefore certain information and footnote
disclosures normally contained in financial statements prepared in accordance
with generally accepted accounting principles have been condensed or omitted.

The accompanying interim financial statements should be read in conjunction with
the Company's registration statement on form S-1 for the year ended December 31,
1995, which contains information about the Company's financial statements and 
accounting practices.

The accompanying unaudited financial statements of the Company reflect all
adjustments of a  normal recurring nature which are, in the opinion of
management, necessary to present a fair statement of the financial position as
of June 30, 1996 and the results of operations and cash flows for the interim
periods presented.

2.  REVENUE RECOGNITION

The Company recognizes revenues from licenses of computer software provided that
a noncancelable license agreement has been signed, the software and related
documentation have been shipped, there are no material uncertainties regarding
customer acceptance, collection of the resulting receivable is deemed probable,
and no other significant vendor obligations exist. Maintenance revenues are
deferred and recognized over the related contract period, generally three months
to five years. Services and other revenues generated from professional
consulting and training services and software customization services are
recognized as the services are performed. Hardware revenues are recognized upon
shipment.

RESULTS OF OPERATIONS


THIS MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF
OPERATIONS INCLUDES A NUMBER OF FORWARD-LOOKING STATEMENTS WHICH REFLECT THE
COMPANY'S CURRENT VIEWS WITH RESPECT TO FUTURE EVENTS AND FINANCIAL PERFORMANCE.
THESE FORWARD-LOOKING STATEMENTS ARE SUBJECT TO CERTAIN RISKS AND UNCERTAINTIES,
INCLUDING THOSE DISCUSSED BELOW, THAT COULD CAUSE RESULTS TO DIFFER MATERIALLY

OVERVIEW

ULTRADATA Corporation (the "Company") develops and markets open architecture,
on-line information processing systems for the credit union and financial
services markets. The Company's core ULTRAFIS system, together with its array of
complementary application modules, provides an open architecture, fully-
integrated on-line information processing system with advanced database
management capabilities that supports financial services such as checking,
savings and investment accounts, credit and debit cards, ATM access and consumer
lending. The ULTRAFIS system was designed specifically to take advantage of open
mainstream computing standards such as the UNIX operating system and SQL-
compatible databases. The Company's products provide networking independence and
run on a broad range of industry-leading UNIX hardware platforms.

The Company has also developed client-server application modules such as the
Company's Automated Loan Processing System product, which was introduced for
existing ULTRAFIS system customers in the second half of 1994 and UltraAccess
Remote Banking, which was introduced in the second quarter of 1996. The Company
plans to market UltraAccess and other client-server application modules as stand
alone products for credit unions and other segments of the financial services
market.

The Company derives its revenues from software license fees, maintenance fees,
service bureau operation fees and disaster recovery services, custom
development, training and installation services and sales of third party
software and hardware products. A significant portion of the Company's revenues
are derived from substantial contracts with organizations that have long
decision-making cycles, typically from six to twelve months. The decision to
purchase the Company's products is followed by an installation and training
cycle, which is labor-intensive and generally requires from three to twelve
months to complete.

RESULTS OF OPERATIONS

REVENUES

Revenues for the three months ended June 30, 1996 increased 158% over the same
period last year from $5.0 million to  $12.9 million. In the first six months of
1996 revenues increased  117% to $25.0 million compared to $11.5 million for the
same period in 1995.

The following table sets forth the Company's revenue and gross margin and gross
margin as a percentage of revenues for the three month periods ended June 30,
1996 and 1995, respectively:

</TABLE>
Software revenues increased by 245% from $1.4 million in the second quarter of
1995 to $5.0 million in the second quarter of 1996. Software revenues increased
176% from $2.9 million in the first six months of 1995 to $8.1 million during
the same period of 1996. The increase in software revenues during the second
quarter of 1996 was due primarily to a continued growth in the number of new
customer contracts, the release of the Company's add-on Financial Services
Platform application module, continued demand for the Company's new add-on
UltraAccess Remote Banking application module, as well as the first sale of the
Company's UltraAccess application module to a non-ULTRAFIS system customer.

Maintenance revenues increased by 14% from $1.8 million in the second quarter of
1995 to $2.0 million in the second quarter of 1996.  Maintenance revenue
increased by 12% from $3.5 million in the six months ended June 30, 1995 to $4.0
million during the same period of 1996.  The increase was primarily a result of
growth in new ULTRAFIS system customers and add-on module sales.  The Company's
installed customer base grew from approximately 160 systems on June 30, 1995 to
approximately 171 systems on June 30, 1996.

Services and other revenues increased by 115% from $1.0 million in the second
quarter of 1995 to $2.1 million in second quarter of 1996. Services and other
revenue increased by 90% from $2.1 million in the first six months of 1995 to
$3.9 million during the same period of 1996. The revenue growth was mainly
attributable to increases in training and installation activities. Services and
other revenues also includes custom development, service bureau operation fees
and disaster recovery contracts.

Hardware revenues increased from $864,000 in the second quarter 1995 to $3.9
million in the second quarter of 1996. This 352% increase was primarily
attributable to the increase in the number of new customer hardware purchases.
Hardware revenue associated with new customer purchases was $157,000 for the
second quarter of 1995 compared to $2.3 million for the second quarter of 1996.
Hardware revenue increased 200% from $3.0 million in the six months ended June
30, 1995 to $9.0 million during the same period of 1996.

In the second quarter of 1996, revenues from hardware sales represented
approximately 30% of total revenues, compared to approximately 17% of total
revenues in the second quarter of 1995.  The percentage of hardware revenues
depends on the mix of customer orders and the timing of particular customer
installations and can be expected to fluctuate substantially from quarter to
quarter.

Gross margin as a percentage of total revenue declined 4% from 49% in the second
quarter of 1995 to 45% in second quarter of 1996 primarily due to declines in
margin for the maintenance and services and other revenues, which were partially
offset by improved software revenues as a percentage of total revenues and
improved margin in the hardware revenues.

                                       8
<PAGE>
 
Software gross margin as a percentage of software revenue declined 4% due to a
higher proportion of sales of software purchased and licensed from third
parties. This change in mix was due to the higher volume of upgrades and new
customer sales requiring third party software. The software gross margin as a
percentage of software revenue also declined by 7% for the six months ending
June 30, 1995 compared to the same period in 1996.

Gross margin percentage from services and other revenues declined by 16% for the
second quarter of 1996 primarily due to overruns experienced by the Company
travel and direct expenses for contracts completed during the second quarter.
Additional reductions in margin were caused by an increase in lower margin
training and installation labor services.

Hardware gross margin as a percentage of hardware revenues increased 11% for the
second quarter of 1996 due to the higher margin on the increased volume of new
contract hardware shipped in the second quarter of 1996.

</TABLE>

Product development expenses increased from $943,000 in the second quarter of
1995 to $1.4 million in the second quarter of 1996. The increase was primarily
for staffing to support new product development programs such as UltraAccess
Remote Banking modules, Optical Disk Systems modules, product enhancements, and
regulatory compliance. Product development expenses as a percentage of total
revenues declined from 19% to 11% during the second quarter of 1996 compared to
the same period during 1995. The Company anticipates that future product
development expenses will increase in absolute dollars.

Selling, general and administrative expenses increased from $2.7 million in
second quarter 1995 to $3.5 million in second quarter 1996. The increase was
primarily due to staff increases to address the sale of the Company's increasing
array of application modules to the existing customer base and for enhancing the
product marketing function for these and other new products. Selling, general
and administrative expenses as a percentage of total revenues decreased from 54%
to 27%. The Company anticipates that future selling, general and administrative
expenses will increase in absolute dollars.


INTEREST INCOME, NET

Interest income, net increased to $122,000 in the second quarter of 1996
compared to interest income of $13,000 in the second quarter of 1995, primarily
because of the earnings from investment of the funds generated from the
Company's initial public offering.

FUTURE OPERATING RESULTS

The Company's operating performance each quarter is subject to various risks and
uncertainties as discussed in this report and in the Company's Prospectus dated
February 15, 1996. This report on Form 10-Q should be read in conjunction with
such Prospectus, particularly "Risk Factors" and "Management's Discussion and
Analysis of Financial Condition and Results of Operations" contained therein.
The Company's future operating results will depend upon conditions in its market
that may affect demand for its products and its abilities to enhance its
existing products and introduce new products on a timely basis. The Company must
also manage growth effectively as failure to do so could materially and
adversely affect its business and operating results. In particular, the Company
has reorganized its management structure in an effort to address change in its
business and is adapting it's financial and operational control systems to
respond to such changes. The Company is in the early stages of this
reorganization process and there can be no assurances that the Company will
achieve these objectives. In addition, installation of the Company's ULTRAFIS
system is a complex process that must typically be done without any disruption
of the customer's service. Because a portion of the Company's contracts
typically include development of custom software, a failure by the Company to
anticipate the time and expenses associated with such development could result
in increased costs, delays or reduced revenues and margin. Failure by the
Company to successfully install an ULTRAFIS system could result in significant
loss of revenue in a particular quarter and fluctuation in the Company's results
of operations. Although the Company schedules the installations of its products
several months in advance, its ability to achieve its revenue plans, both in the
near term and in the long term, depends on the Company's continued ability to
sign new customer contracts and to complete such contracts on schedule. A
substantial portion of the Company's revenues for the second quarter were
recorded at or near the end of the quarter. Failure to close new customer
contracts could have a material adverse impact on future operating results.
There can be no assurance that sales will continue to occur at historical rates
or in accordance with the Company's expectations. Because the Company's
operating expenses are based on anticipated revenue levels and a high percentage
of the Company's expenses are relatively fixed, a small variation in the timing
of the recognition of specific revenues could cause significant variations in
operating results from quarter to quarter.

Substantially all of the Company's revenues historically have been related to
the Company's ULTRAFIS system, and the Company expects that for several years a
substantial portion of its revenues will continue to be related to the ULTRAFIS
system. The Company's success will depend in large part on its ability to
maintain and enhance the ULTRAFIS system and to develop, on a timely and cost-
effective basis utilizing new technologies, application modules that meet
evolving customer needs. In addition, a principal focus of the Company's
development activities at this time is the development of standalone products.
This is a market with which the Company is unfamiliar and, although the Company
has sold its first standalone product, UltraAccess Remote Banking, the Company
can not assure that it will be successful in developing and marketing new
standalone products on a timely basis, or that there will be customer demand
for, or acceptance of, such products. Any failure by the Company to anticipate
or to respond adequately to new and changing market conditions, enhance the
ULTRAFIS system and develop application modules, compete with new product
offerings by third parties, complete new standalone product offerings, respond
to emerging industry standards, adapt to changing technologies, maintain sales
of the Company's products, or continue to sign and complete new customer
contracts would have a material adverse effect on the Company's results of
operations.

LIQUIDITY AND CAPITAL RESOURCES

The Company's management believes current cash and cash equivalents, primarily
generated from the proceeds of the initial public offering  and expected cash
generated from operations, will satisfy its expected working capital and capital
expenditure requirements through the immediate future.

The Company currently has no outstanding credit facilities.  The Company is
currently in negotiations for new credit facilities, which are expected to be
available for working capital, as required, and the financing of future capital 
expenditures.  

                                       10
<PAGE>
 
Capital expenditures of $913,000 in the second quarter of 1996 included the
purchase of a new computer system for the Disaster Recovery Center to upgrade
the centers technology capabilities for the system requirements of new customers
as well as to accommodate the increase in the number of customers utilizing the
services.  Computer equipment was also purchased to accommodate the headcount
growth in customer service and product development.

Net cash used for operations was $7.3 million for the six months ending June 30,
1996, $6.2 million of which was due to unbilled revenue, compared to $314,000
provided by operations for the same period in 1995, ($517,000) of which was due
to unbilled revenue. Unbilled revenue, increased to $8.5 million for the six
months ending June 30, 1996 compared to $2.3 million at December 31, 1995. The
Company's contract billing terms typically are spread out over a series of
events (from contract execution through final acceptance) that generally span a
six to nine month period resulting in unbilled revenues. The increase in
unbilled revenue was primarily related to an increase in the number of large
contract sales and add-on and upgrade sales to existing customers for software,
hardware and labor. In addition, the increase was due in part to the
introduction of new application modules and an increase in new ULTRAFIS customer
sales which outpaced the ability of the Company's training and installation
resources to deliver customer implementations. The Company has implemented a new
billing policy during the latter part of the second quarter of 1996 that is
intended to better match the timing of the billing and recognition of revenue,
which should assist in the reduction of the higher level of the unbilled
revenue. Because this policy is new, there can be no assurances that the Company
will realize expected improvements in the near term or that the timing of
collections will occur as expected.

During the six months ended June 30, 1996 deferred revenue decreased $1.8
million primarily due to recognizing revenue from prior period contract sales
and the timing of sales generated for the current period. Deferred revenue is
also a function of the timing differences between the Company's contractual
billing cycle and the revenue recognition policy. If the implementation of the
new billing policy brings the benefits that the Company anticipates it should
create a balancing effect between unbilled revenue and deferred revenue.

During the six months ended June 30, 1996 the increase in accrued expense is
primarily due to accruing for the higher volume of third party vendor hardware
delivered to customers but not invoiced to the Company.

2.   PREMISES.

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

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

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

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

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

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.

     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.

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.

6.   USE.

     6.1  USE.  Lessee shall use and occupy the Premises only for the purposes
set forth in Paragraph 1.8, or any other use which is comparable thereto, and
for no other purpose.  Lessee shall not use or permit the use of the Premises in
a manner that creates waste or a nuisance, or that disturbs owners and/or
occupants of, or causes damage to, neighboring premises or properties.  Lessor
hereby agrees to not unreasonably withhold or delay its consent to any written
request by Lessee, Lessees assignees or subtenants, and by prospective assignees
and subtenants of the Lessee, its assignees and subtenants, for a modification
of said permitted purpose for which the premises may be used or occupied, so
long as the same will not impair the structural integrity of the improvements on
the Premises, the mechanical or electrical systems therein, is not significantly
more burdensome to the Premises and the improvements thereon, and is otherwise
permissible pursuant to this Paragraph 6.  If Lessor elects to withhold such
consent, Lessor shall within five (5) business days give a written notification
of same, which notice shall include an explanation of Lessor's reasonable
objections to the change in use.

     6.2  HAZARDOUS SUBSTANCES.

          (a) REPORTABLE USES REQUIRE CONSENT.  The term "Hazardous Substance"
as used in this Lease shall mean any product, substance, chemical, material or
waste whose presence, nature, quantity and/or intensity of existence, use,
manufacture, disposal, transportation, spill, release or effect, either by
itself or in combination with other materials expected to be on the Premises, is
either:  (i) potentially injurious to the public health, safety or welfare, the
environment or the Premises, (ii) regulated or monitored by any governmental
authority, or (iii) a basis for liability of Lessor to any governmental agency
or third party under any applicable statute or common law theory.  Hazardous
Substance shall include, but not be limited to, hydrocarbons,

petroleum, gasoline, crude oil or any products, by-products or fractions
thereof. Lessee shall not engage in any activity in, on or about the Premises
which constitutes a Reportable Use (as hereinafter defined) of Hazardous
Substances without the express prior written consent of Lessor and compliance in
a timely manner (at Lessee's sole cost and expense) with all Applicable Law (as
defined in Paragraph 6.3). "Reportable Use" shall mean (i) the installation or
use of any above or below ground storage tank, (ii) the generation, possession,
storage, use, transportation, or disposal of a Hazardous Substance that requires
a permit from, or with respect to which a report, notice, registration or
business plan is required to be filed with, any governmental authority.
Reportable Use shall also include Lessee's being responsible for the presence
in, on or about the Premises of a Hazardous Substance with respect to which any
Applicable Law requires that a notice be given to persons entering or occupying
the Premises or neighboring properties. Notwithstanding the foregoing, Lessee
may, without Lessor's prior consent, but in compliance with all Applicable Law,
use any ordinary and customary materials reasonably required to be used by
Lessee in the normal course of Lessee's business permitted on the Premises, so
long as such use is not a Reportable Use and does not expose the Premises or
neighboring properties to any meaningful risk of contamination or damage or
expose Lessor to any liability therefor. In addition, Lessor may (but without
any obligation to do so) condition its consent to the use or presence of any
Hazardous Substance, activity or storage tank by Lessee upon Lessee's giving
Lessor such additional assurances as Lessor, in its reasonable discretion, deems
necessary to protect itself, the public, the Premises and the environment
against damage, contamination or injury and/or liability therefrom or therefor,
including, but not limited to, the installation (and removal on or before Lease
expiration or earlier termination) of reasonably necessary protective
modifications to the Premises (such as concrete encasements) and/or the deposit
of an additional Security Deposit under Paragraph 5 hereof.

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

          (c) INDEMNIFICATION.  Lessee 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 or caused to be brought to the Premises
by or for Lessee.  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 or 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, or under the Premises, including soil and groundwater conditions, and
(iii) the use, generation, manufacture, production, installation, maintenance,
removal, transportation, storage, spill or release of any Hazardous Substance or
storage tank), now in effect or which may hereafter come into effect, and
whether or not reflecting a change in policy from any previously existing
policy. Lessee shall, within five (5) days after receipt of Lessor's written
request, provide Lessor with copies of all documents and information, including,
but not limited to, permits, registrations, manifests, applications, reports and
certificates, evidencing Lessee's compliance with any Applicable Law specified
by Lessor, and shall immediately upon receipt, notify Lessor in writing (with
copies of any documents involved) of any threatened or actual claim, notice,
citation, warning, complaint or report pertaining to or involving failure by
Lessee or the Premises to comply with any Applicable Law.

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

     ALTERATIONS.

     7.1  LESSEE'S OBLIGATIONS.

          (a) Subject to the provisions of Paragraphs 2.2 (Lessor's warranty as
to condition), 2.3 (Lessor's warranty as to compliance with covenants, etc.),
7.2 (Lessor's obligations to repair), 9 (damage and destruction), and 14
(condemnation), Lessee shall, at Lessee's sole cost and expense and at all
times, keep the Premises and every part thereof in good order, condition and
repair (whether or not such portion of the Premises requiring repairs, or the
means of repairing the same, are reasonably or readily accessible to Lessee, and
whether or not the need for such repairs occurs as a result of Lessee's use, any
prior use, the elements or the age of such portion of the Premises), including,
without limiting the generality of the foregoing all equipment or facilities
serving the Premises, such as plumbing, heating, air conditioning, ventilating,
electrical, lighting facilities, boilers, fired or unfired pressure vessels,
fire sprinkler and/or standpipe and hose or other automatic fire extinguishing
system, including fire alarm and/or smoke detection systems and equipment,
fixtures, walls (interior), ceilings, windows, doors, plate glass, skylights,
signs, (but only such items as are inside the building) located in, on, about,
or adjacent to the Premises.  Lessee shall not cause or permit any Hazardous
Substance to be spilled or released in, on, under or about the Premises
(including through the plumbing or sanitary sewer system) and shall promptly, at
Lessee's expense, take all investigatory and/or remedial action reasonably
recommended, whether or not formally ordered or required, for the cleanup of any
contamination of, and for the maintenance, security and/or monitoring of the
Premises, the elements surrounding same, or neighboring properties, that was
caused or materially contributed to by Lessee, or pertaining to or involving any
Hazardous Substance and/or storage tank brought onto the Premises by or for
Lessee or under its control.  Lessee, in keeping the Premises in good order,
condition and repair, shall exercise and perform good maintenance practices.
Lessee's obligations shall include restorations, replacements or renewals when
necessary to keep the Premises and all improvements thereon or a part thereof in
good order, condition and state of repair.  If Lessee occupies the Premises for
seven (7) years or more, Lessor may require Lessee to repaint the exterior of
the

buildings on the Premises as reasonably required, but not more frequently
than once every seven (7) years.  Additionally, to the extent Lessor benefits
from recovery on any extended warranties or legal actions regarding defects in
the items Lessee is required to maintain and replace under this paragraph.

          (b) Lessee shall, at Lessee's sole cost and expense, procure and
maintain contracts, with copies to Lessor, in customary form and substance for
and with contractors specializing and experienced in, the inspection,
maintenance and service of the following equipment and improvements, if any,
located on the Premises:  (i) heating, air conditioning and ventilation
equipment, (ii) boiler, fired or unfired pressure vessels, (iii) fire sprinkler
and/or standpipe and hose or other automatic fire extinguishing systems,
including fire alarm and/or smoke detection.

     7.2  LESSOR'S OBLIGATIONS.  Except for the warranties and agreements of
Lessor contained in Paragraphs 2.2 (relating to condition of the Premises), 2.3
(relating to compliance with covenants, restrictions and building code), 9
(relating to destruction of the Premises) and 14 (relating to condemnation of
the Premises), it is intended by the Parties hereto that Lessor have no
obligation, in any manner whatsoever, to repair and maintain the Premises, the
improvements located thereon, or the equipment therein, whether structural or
non structural, all of which obligations are intended to be that of the Lessee
under Paragraph 7.1 hereof.  It is the intention of the Parties that the terms
of this Lease govern the respective obligations of the Parties as to maintenance
and repair of the Premises.  Lessee and Lessor expressly waive the benefit of
any statute now or hereafter in effect to the extent it is inconsistent with the
terms of this Lease with respect to, or which affords Lessee the right to make
repairs at the expense of Lessor or to terminate this Lease by reason of any
needed repairs.

     7.3  UTILITY INSTALLATIONS; TRADE FIXTURES; ALTERATIONS.

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

          (b) CONSENT.  Any Alterations or Utility Installations that Lessee
shall desire to make and which require the consent of the Lessor shall be
presented to Lessor in written form with proposed detailed plans.  All consents
given by Lessor, whether by virtue of Paragraph 7.3(a) or by subsequent specific
consent, shall be deemed conditioned upon: (i) Lessee's acquiring all applicable
permits required by governmental authorities, (ii) the furnishing of copies of
such permits together with a copy of the plans and specifications for the
Alteration or Utility Installation to Lessor prior to commencement of the work
thereon, and (iii) the compliance by Lessee with all conditions of said permits
in a prompt and expeditious manner.  Any Alterations or Utility Installations by
Lessee during the term of this Lease shall be done in a good and workmanlike
manner, with good and sufficient materials, and in compliance with all
Applicable Law.  Lessee shall promptly upon completion thereof furnish Lessor
with as-built plans and specifications therefor.  Lessor may (but without

obligation to do so) condition its consent to any requested Alteration or
Utility Installation that costs $10,000 or more upon Lessee's providing Lessor
with a lien and completion bond in an amount equal to one and one-half times the
estimated cost of such Alteration or Utility Installation.

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

     7.4  OWNERSHIP; REMOVAL; SURRENDER; AND RESTORATION.

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

          (b) REMOVAL.  Unless otherwise agreed in writing, Lessor may require
that any or all Lessee Owned Alterations or Utility Installations be removed by
the expiration or earlier termination of this Lease, notwithstanding their
installation may have been consented to by Lessor.  Lessor may require the
removal at any time of all or any part of any Lessee Owned Alterations or
Utility Installations made without the required consent of Lessor.

          (c) SURRENDER/RESTORATION.  Lessee shall surrender the Premises by the
end of the last day of the Lease term or any earlier termination date, with all
of the improvements, parts and surfaces thereof clean and free of debris and in
good operating order, condition and state of repair, ordinary wear and tear
excepted.  "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 this 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.  Lessee's 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 $2,000,000 per occurrence.  Premiums for policy
periods commencing prior to or extending beyond the Lease term shall be prorated
to correspond to the Lease term.  Payment shall be made by Lessee to Lessor
within ten (10) days following receipt of an invoice 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 $2,000,000 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 insurance 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 shall also maintain liability insurance described in Paragraph 8.2(a),
above, in addition to, and not in lieu of, the insurance required to be
maintained by Lessee.  Lessee shall not be named as an additional insured
therein.

     8.3  PROPERTY INSURANCE--BUILDING, IMPROVEMENTS AND RENTAL VALUE.

          (a) BUILDING AND IMPROVEMENTS.  The Insuring Party (as defined in
Section 1.9 above, Lessor) 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,
but in no event more than the commercially reasonable and available insurable
value thereof if, by reason of the unique nature or age of the improvements
involved, such latter amount is less than full replacement cost.  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 including
coverage for any additional costs resulting from debris removal and reasonable
amounts of coverage for the enforcement of any ordinance or law regulating the
reconstruction or replacement of any undamaged sections of the Premises required
to be demolished or removed by reason of the enforcement of any building,
zoning, safety or land use laws as the result of a covered cause of loss.  Said
policy or policies shall also contain an agreed valuation provision in lieu of
any coinsurance clause, waiver of subrogation, and inflation guard protection
causing an increase in the annual property insurance coverage amount by a factor
of not less than the adjusted U.S. Department of Labor Consumer Price Index for
All Urban Consumers for the city nearest to where the Premises are located.  If
such insurance coverage has a deductible clause, the deductible amount shall not
exceed $1,000

NET                                                               Initials _____

per occurrence, and Lessee shall be liable for such deductible amount in the
event of an Insured Loss, as defined in Paragraph 9.1(c).

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

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

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

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

     8.5  INSURANCE POLICIES.  Insurance required hereunder shall be in
companies duly licensed to transact business in the state where the Premises are
located, and maintaining during the policy term a "General Policyholders
Rating", of at least B+, V, or such other rating as may be required by a Lender
having a lien on the Premises, as set forth in the most current issue of "Best's
Insurance Guide."  Lessee shall not do or permit to be done anything which shall
invalidate the insurance policies referred to in this Paragraph 6.  If Lessee is
the Insuring Party, Lessee shall cause to be delivered to Lessor certified
copies of policies of such insurance or certificates evidencing the existence
and amounts of such insurance with the insureds and loss payable clauses as
required by this Lease.  No such policy shall be cancellable or subject to
modification except after thirty (30) days prior written notice to Lessor.
Lessee shall at least thirty (30) days prior to the expiration of such policies,
furnish Lessor with evidence of renewals or "insurance binders" evidencing
renewal thereof, or Lessor may order such insurance and charge the cost thereof
to Lessee, which amount shall be payable by Lessee to Lessor upon demand.  If
the Insuring Party shall fail to procure and maintain the insurance required to
be carried by the Insuring Party under this Paragraph 8, the other Party may,
but shall not be required to, procure 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.

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

     8.8.  EXEMPTION OF LESSOR FROM LIABILITY.  Except for Lessor's negligence
and/or breach of express warranties, 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 of breach of
this Lease, Lessor shall under no circumstances be liable for injury to Lessee's
business or for any loss of income or profit therefrom.

9.   DAMAGE OR DESTRUCTION.

     9.1  DEFINITIONS.

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

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

          (c) "INSURED LOSS"  shall mean damage or destruction to improvements
on the Premises, other than Lessee Owned Alterations and Utility Installations,
which was caused by an event required to be 

NET                                                               Initials _____

covered by the insurance described in Paragraph 8.3(a), irrespective of any
deductible amounts or coverage limits involved.

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

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

     9.2  PARTIAL DAMAGE--INSURED LOSS.  If a Premises Partial Damage that is
an Insured Loss occurs, then Lessor shall, at Lessor's expense, repair such
damage (but not Lessee's Trade Fixtures or Lessee Owned Alterations and Utility
Installations) as soon as reasonably possible and this Lease shall continue in
full force and effect; provided, however, that Lessee shall, at Lessor's
election, make the repair of any damage or destruction the total cost to repair
of which is $10,000 or less, and, in such event, Lessor shall make the insurance
proceeds available to Lessee on a reasonable basis for that purpose.
Notwithstanding the foregoing, if the required insurance was not in force or the
insurance proceeds are not sufficient to effect such repair, the Insuring Party
shall promptly contribute the shortage in proceeds (except as to the deductible
which is Lessee's responsibility) as and when required to complete said repairs.
In the event, however, the shortage in proceeds was due to the fact that, by
reason of the unique nature of the improvements, full replacement cost insurance
coverage was not commercially reasonable and available, Lessor shall have no
obligation to pay for the shortage in insurance proceeds or to fully restore the
unique aspects of the Premises unless Lessee provides Lessor with the funds to
cover same, or adequate assurance thereof, within ten (10) days following
receipt of written notice of such shortage and request therefor.  If Lessor
receives said funds of adequate assurance thereof within said ten (10) day
period, the party responsible for making the repairs shall complete them as soon
as reasonably possible and this Lease shall remain in full force and effect.  If
Lessor does not receive such funds or assurance within said period, Lessor may
nevertheless elect by written notice to Lessee within ten (10) days thereafter
to make such restoration and repair as is commercially reasonable with Lessor
paying any shortage in proceeds, in which case this Lease shall remain in full
force and effect.  If in such case Lessor does not so elect, then this Lease
shall terminate sixty (60) days following the occurrence of the damage or
destruction.  Unless otherwise agreed, Lessee shall in no event have any right
to reimbursement from Lessor for any, funds contributed by Lessee to repair any
such damage or destruction.  Premises Partial Damage due to flood or earthquake
shall be subject to Paragraph 9.3 rather than Paragraph 9.2, notwithstanding
that there may be some insurance coverage, but the net proceeds of any such
insurance shall be made available for the repairs if made by either Party.

     9.3  PARTIAL DAMAGES--UNINSURED LOSS.  If a Premises Partial Damage that is
not an insured Loss occurs, unless caused by a negligent or willful act of
Lessee (in which event Lessee shall make the repairs at Lessee's expense and
this Lease shall continue in full force and effect,  but subject to Lessor's
rights under Paragraph 13), Lessor may at Lessor's option, either:  (i) repair
such damage as soon as reasonably possible at Lessor's expense, in which event
this Lease shall continue in full force and effect, or (ii) give written notice
to Lessee within thirty (30) days after receipt by Lessor of knowledge of the
occurrence of such damage of Lessor's desire to terminate this Lease as of the

elects to give such notice of Lessor's intention to terminate this Lease, Lessee
shall have the right within ten (10) days after the receipt of such notice to
give written notice to Lessor of Lessee's commitment to pay for the repair of
such damage totally at Lessee's expense and without reimbursement from Lessor.
Lessee shall provide Lessor with the required funds or satisfactory assurance

specified above, this Lease shall terminate as of the date specified in Lessor's
notice of termination.

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

     9.5  DAMAGE NEAR END OF TERM.  If at any time during the last six (6)
months of the term of this Lease there is damage for which the cost to repair
exceeds one (1) month's Base Rent, whether or not an Insured Loss, Lessor may,
at Lessor's option, terminate this Lease effective sixty (60) days following the
date of occurrence of such damage by giving written notice to Lessee of Lessor's
election to do so within thirty (30) days after the date of occurrence of such
damage; provided, however, if Lessee at that time has an exercisable option to
extend this Lease or to purchase the Premises, then Lessee may preserve this
Lease by, within twenty (20) days following the occurrence of the damage, or
before the expiration of the time provided in such option for its exercise,
whichever is earlier ("Exercise Period"), (i) exercising such option and (ii)
providing Lessor with any shortage in insurance proceeds (or adequate assurance
thereof) needed to make the repairs.  If Lessee duly exercises such option
during said Exercise Period and provides Lessor with funds (or adequate
assurance thereof) to cover any shortage in insurance proceeds, Lessor shall, at
Lessor's expense repair such damage as soon as reasonably possible and this
Lease shall continue in full force and effect.  If Lessee fails to exercise such
option and provide such funds or assurance during said Exercise Period, then
Lessor may at Lessor's option terminate this Lease as of the expiration of said
sixty (60) day period following the occurrence of such damage by giving written
notice to Lessee of Lessor's election to do so within ten (10) days after the
expiration of the Exercise Period, notwithstanding any term or provision in the
grant of option to the contrary.

     9.6  ABATEMENT OF RENT; LESSEE'S REMEDIES.

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

          (b) If Lessor shall be obligated to repair or restore the Premises
under the provisions of this Paragraph 9, Lessor shall not commence, in a
substantial and meaningful way, the repair of restoration of the Premises within
thirty (30) days after such obligation shall accrue provided, however, that for
the first five (5) years of the Term, Lessee shall not incur the burden of any
increase in taxes that results from a transfer, sale or refinance of the
Premises, Lessee may, give written notice to Lessor and to any Lenders of which
Lessee has actual notice of Lessee's election to terminate this Lease.
"Commence" as used in this Paragraph shall mean either the unconditional
authorization of the preparation of the required plans, or the beginning of the
actual work on the Premises, whichever first occurs.

     9.7  HAZARDOUS SUBSTANCE CONDITIONS.  If a Hazardous Substance Condition
occurs, unless Lessee is legally responsible therefor (in which case Lessee
shall make the investigation and remediation thereof required by Applicable Law

rights

under Paragraph 13), Lessor may at Lessor's option either (i) investigate and
remediate such Hazardous Substance Condition, if required, as soon as reasonably
possible at Lessor's expense, in which event this Lease shall continue in full
force and effect, or (ii) if the estimated cost to investigate and remediate
such condition exceeds twelve (12) times the then monthly Base Rent or $100,000,
whichever is greater, give written notice to Lessee within thirty (30) days
after receipt by Lessor of knowledge of the occurrence of such Hazardous
Substance Condition of Lessor's desire to terminate this Lease as of the date
sixty (60) days following the giving of such notice. In the event Lessor elects
to give such notice of Lessor's intention to terminate this Lease, Lessee shall
have the right within ten (10) days after the receipt of such notice to give
written notice to Lessor or Lessee's commitment to pay for the investigation and
remediation of such Hazardous Substance Condition totally at Lessee's expense
and without reimbursement from Lessor except to the extent of an amount equal to
twelve (12) times the then monthly Base Rent of $100,000, whichever is greater.
Lessee shall provide Lessor with the funds required of Lessee or satisfactory
assurance thereof within thirty (30) days following Lessee's said commitment. In
such event this Lease shall continue in full force and effect, and Lessor shall
proceed to make such investigation and remediation as soon as reasonably
possible and the required funds are available. If Lessee does not give such
notice and provide the required funds or assurance thereof within the times
specified above, this Lease shall terminate as of the date specified in Lessor's
notice of termination. If a Hazardous Substance Condition occurs for which
Lessee is not legally responsible, there shall be abatement of Lessee's
obligations under this Lease to the same extent as provided in Paragraph 9.6(a)
for a period of not to exceed twelve (12) months.

     9.8  TERMINATION--ADVANCE PAYMENTS.  Upon termination of this Lease
pursuant to this Paragraph 9, an equitable adjustment shall be made concerning
advance Base Rent and any other advance payments made by Lessee to Lessor.
Lessor shall, in addition, return to Lessee as much of Lessee's Security Deposit
as has not been, or is not then required to be, used by Lessor under the terms
of this Lease.

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

10.  REAL PROPERTY TAXES.

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

           (b) ADVANCE PAYMENT.  In order to insure payment when due and before
delinquency of any or all Real Property Taxes, Lessor reserves the right, at
Lessor's option, to estimate the current Real Property Taxes applicable to the
Premises, and to require such current year's Real Property Taxes to be paid in
advance to Lessor by Lessee, either:  (i) in a lump sum amount equal to the
installment due, at least twenty (20) days prior to the applicable delinquency
date, or (ii) monthly in advance with the payment of the Base Rent.  If Lessor
elects to require payment monthly, in advance, the monthly payment shall be that
equal monthly amount which, over the number of months remaining before the month
in which the applicable tax installment would become delinquent (and without
interest thereon), would provide a fund large enough to fully discharge before
delinquency the estimated installment of taxes to be paid.  When the actual
amont of the applicable tax bill is 

NET                                                               Initials _____

known, the amount of such equal monthly advance payment shall be adjusted as
required to provide the fund needed to pay the applicable taxes before
delinquency. If the amounts paid to Lessor by Lessee under the provisions of
this Paragraph are insufficient to discharge the obligations of Lessee to pay
such Real Property Taxes as the same become due, Lessee shall pay to Lessor,
upon Lessor's demand, such additional sums as are necessary to pay such
obligations. All moneys paid to Lessor under this Paragraph may be intermingled
with other moneys of Lessor and shall not bear interest. In the event of a
Breach by Lessee in the performance of the obligations of Lessee under this
Lease, then any balance of funds paid to Lessor under the provisions of this
Paragraph may, subject to proration as provided in Paragraph 10.1(a), at the
option of Lessor, be treated as an additional Security Deposit under Paragraph
5.

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

     10.3  JOINT ASSESSMENT.  If the Premises are not separately assessed,
Lessee's liability shall be an equitable proportion of the Real Property Taxes
for all of the land and improvements included within the tax parcel assessed,
such proportion to be determined by Lessor from a respective valuations *
provided, however, that for the first five (5) years of the term, Lessee shall
not incur the burden of any increase in taxes that results from a transfer,
sale, or refinance of the Premises.

     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
reasonably 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 any subject to the terms of
Paragraph 36.

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

          (d) An assignment or subletting of Lessee's interest in this Lease
without Lessor's specific prior written consent shall, at Lessor's option, be a
Default curable after notice per Paragraph 13.1(c), or a noncurable Breach
without the necessity of any notice and grace period.  If Lessor elects to treat
such unconsented to assignment or subletting as a noncurable Breach, Lessor
shall have the right to either:  (i) terminate this Lease, or (ii) upon thirty
(30) days written notice ("Lessor's Notice"), increase the monthly Base Rent to
fair market rental value or one hundred ten percent (110%) of the Base Rent then
in effect, whichever is greater.  Pending determination of the new fair market
rental value, if disputed by Lessee, Lessee shall pay the amount set forth in
Lessor's Notice, with any overpayment credited against the next installment(s)
of Base Rent coming due, and any underpayment for the period retroactively to
the effective date of the adjustment being due and payable immediately upon the
determination thereof.  Further, in the event of such Breach and market value
adjustment, (i) the purchase price of any option to purchase the Premises held
by Lessee shall be subject to similar adjustment to the then fair market value
(without the Lease being considered an encumbrance or any deduction for
depreciation or obsolescence, and considering the Premises at its highest and
best use and in good condition), or one hundred ten percent (110%) of the price
perviously in effect, whichever is greater, (ii) any index-oriented rental or
price adjustment formulas contained in this Lease shall be adjusted to require
that the base index be determined with reference to the index applicable to the
time of such adjustment, and (iii) any fixed rental adjustments scheduled during
the remainder of the Lease term shall be increased in the same ratio as the new
market rental bears to the Base Rent in effect immediately prior to the market
value adjustment.

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

     12.2  TERMS AND CONDITIONS APPLICABLE TO ASSIGNMENT AND SUBLETTING.

          (a) Regardless of Lessor's consent, any assignment or subletting shall
not:  (i)  be effective without the express written assumption by such assignee
or sublessee of the obligations of Lessee under this Lease, (ii) release Lessee
of any obligations hereunder, or (iii) after 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.

          (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.  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 confirm and comply with each
and every term, covenant, condition and obligation herein to be observed or
performed by Lessee during the term of said assignment or sublease, other than
such obligations as are contrary to or inconsistent with provisions of an
assignment or sublease to which Lessor has specifically consented in writing.

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

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

          (b) In the event of a Breach by Lessee in the performance of its
obligations under this Lease, Lessor, at its option and without any obligation
to do so, may require any sublessee to attorn to Lessor, in which event Lessor
shall undertake the obligations of the sublessee 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.

sublease shall also require the consent of Lessor herein.

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

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

13.  DEFAULT; BREACH; REMEDIES.

     13.1  DEFAULT; BREACH.  Lessor and Lessee agree that if an attorney is
consulted by Lessor in connection with a Lessee Default or Breach (as
hereinafter defined), $350.000 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" is defined as the occurrence of any one or more of the following
Defaults, and, where a grace period for cure after notice is specified herein,
the failure by Lessee to cure such Default prior to the expiration of the
applicable grace period, shall entitle Lessor to pursue the remedies set forth
in Paragraphs 13.2 and/or 13.3:

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

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

          (c) Except as expressly otherwise provided in this Lease, the failure
by Lessee to provide Lessor with reasonable written evidence (in duly executed
original form, if applicable) of (i) compliance with Applicable Law per
Paragraph 6.3, (ii) the inspection, maintenance and service contracts required
under Paragraph 7.1(b), (iii) the 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 (vii) any other documentation or
information which Lessor may reasonably require of Lessee under the terms of
this Lease, where any such failure continues for a period of ten (10) days
following written notice 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,

commences such cure within said thirty (30) day period and thereafter diligently
prosecutes such cure to completion.

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. (S)101 or any
successor statute thereto (unless, in the case of a petition filed against
Lessee, the same is dismissed within sixty (60) days); (iii) the appointment of
a trustee or receiver to take possession of substantially all of Lessee's assets
located at the Premises or of Lessee's interest in this Lease, where possession
is not restored to Lessee within thirty (30) days; or (iv) the attachment,
execution or other judicial seizure of substantially all of Lessee's assets
located at the Premises or of Lessee's interest in this Lease, where such
seizure is not discharged within thirty (30) days; provided, however, in the
event that any provision of this subparagraph (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 insolvent or the subject of a
bankruptcy filing, (iv) a guarantor's refusal to honor the guaranty, or (v) a
guarantor's breach of its guaranty obligation on an anticipatory breach basis,
and Lessee's failure, within sixty (60) days following written notice by or on
behalf of Lessor to Lessee of any such event to provide Lessor with written
alternative assurance or security, which, when coupled with the then existing
resources of Lessee, equals or exceeds the combined financial resources of
Lessee and the guarantors that existed at the time of execution of this Lease.

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

          (a) Terminate Lessee's right to possession of the Premises by any
lawful means, in which case this Lease and the term hereof shall terminate and
Lessee shall immediately surrender possession of the Premises to Lessor.  In
such event Lessor shall be entitled to recover from Lessee:  (i) the worth at
the time of the award of the unpaid rent which had been earned at the time of
termination; (ii) the worth at the time of award of the amount by which the
unpaid rent which would have been earned after termination until the time of
award exceeds the amount of such rental loss that the Lessee proves could have
been reasonably avoided; (iii) the worth at the time of award of the amount by
which the unpaid rent for the balance of the term after the time of award
exceeds the amount of such rental loss that the Lessee proves could be
reasonably avoided; and (iv) any other amount necessary to compensate Lessor for
all the detriment proximately caused by the Lessee's failure to perform its
obligations under this Lease or which in the ordinary course of things would be
likely to result therefrom, including but not limited to the cost of recovering
possession of the Premises, expenses of reletting, including necessary
renovation and alteration of the Premises, reasonable attorneys' fees, and that
portion of the leasing commission paid by Lessor applicable to the unexpired
term of this Lease.  The worth at the time of

                                                                           _____

award of the amount referred to in provision (iii) of the prior sentence shall
be computed by discounting such amount at the discount rate of the Federal
Reserve Bank of San Francisco at the time of award plus one percent (1%).
Efforts by Lessor to mitigate damages caused by Lessee's Default or Breach of
this Lease shall not waive Lessor's right to recover damages under this
Paragraph. If termination of this Lease is obtained through the provisional
remedy of unlawful detainer, Lessor shall have the right to recover in such
proceeding the unpaid rent and damages as are recoverable therein, or Lessor may
reserve therein the right to recover all or any part thereof in a separate suit
for such rent and/or damages. If a notice and grace period required under
subparagraphs 13.1(b), (c) or (d) was not previously given, a notice to pay rent
or quit, or to perform or quit, as the case may be, given to Lessee under any
statute authorizing the forfeiture of leases for unlawful detainer shall also
constitute the applicable notice for grace period purposes required by
subparagraphs 13.2(b), (c) or (d). In such case, the applicable grace period
under subparagraphs 13.1(b), (c) or (d) and under the unlawful detainer statute
shall run concurrently after the one such statutory notice, and the failure of
Lessee to cure the Default within the greater of the two such grace periods
shall constitute both an unlawful detainer and a Breach of this Lease entitling
Lessor to the remedies provided for in this Lease and/or by said statute.

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

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

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

     13.3  INDUCEMENT RECAPTURE IN EVENT OF BREACH.  Any agreement by Lessor for
free or abated rent or other charges applicable to the Premises, or for the
giving or paying by Lessor to or for Lessee of any cash of other bonus,
inducement or consideration for Lessee's entering into this Lease, all of which
concessions are hereinafter referred to as "Inducement Provisions," shall be
deemed conditioned upon Lessee's full and faithful performance of all of the
terms, covenants and conditions of this Lease to be performed or observed by
Lessee during the term hereof as the same may be extended.  Upon the occurrence
of a Breach of this Lease by Lessee, as defined in Paragraph 13.1, any such
inducement Provision shall automatically be deemed deleted from this Lease and
of no further force or effect, and any rent, other charge, bonus, inducement or
consideration theretofore abated, given or paid by Lessor under such an
inducement Provision shall be immediately due and payable by Lessee to Lessor,
and recoverable by Lessor as additional rent due under this Lease,
notwithstanding any subsequent cure of said Breach by Lessee.  The acceptance by
Lessor of rent or the cure of the Breach which initiated the operation of this
Paragraph shall not be deemed a waiver by Lessor of the provisions of this
Paragraph unless specifically so stated in writing by Lessor at the time of such
acceptance.

     13.4  LATE CHARGES.  Lessee hereby acknowledges that late payment by Lessee
to Lessor of rent and other sums due hereunder will cause Lessor to incur costs
not contemplated by this Lease, the exact amount of which will be extremely
difficult to ascertain.  Such costs include, but are not limited to, processing
and accounting charges, and late charges into 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 seven (7) days after such
amount shall be due, 

NET                                                               Initials _____
                                                                           _____

                                     Page 19
<PAGE>
 
then, without any requirement for notice to Lessee, Lessee shall pay to Lessor a
late charge equal to two percent (2%) of such overdue amount. The parties hereby
agree that such late charge represents a fair and reasonable estimate of the
costs Lessor will incur by reason of late payment by Lessee. Acceptance of such
late charge by Lessor shall in no event constitute a waiver of Lessee's Default
or Breach with respect to such overdue amount, nor prevent Lessor from
exercising any of the other rights and remedies granted hereunder. In the event
that a late charge is payable hereunder, whether or not collected, for three (3)
consecutive installments of Base Rent, than notwithstanding Paragraph 4.1 or any
other provision of this Lease to the contrary, Base Rent shall, at Lessor's
option, become due and payable quarterly in advance.

     13.5  BREACH BY LESSOR.  Lessor shall not be deemed in breach of this Lease
unless Lessor fails within a reasonable time to perform an obligation required
to be performed by Lessor.  For purposes of this Paragraph 13.5, a reasonable
time shall in no event be less than thirty (30) days after receipt by Lessor,
and by the holders of any ground lease, mortgage or deed of trust covering the
Premises whose name and address shall have been furnished Lessee in writing for
such purpose, of written notice specifying wherein such obligation of Lessor had
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.

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 title or
possession, whichever first occurs.  If more than ten percent (10%) of the floor
area of the Premises, or more than twenty-five percent (25%) of the land area
not occupied by any building, is taken by condemnation, Lessee may, at 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 affect 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 damage 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  The Brokers named in Paragraph 1.10 are the only Brokers involved in
this Lease.

     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 

NET                                                               Initials _____

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  Lessor and Lessee hereby consent to and approve all agency
relationships, including any dual agencies, indicated in Paragraph 1.10.

16.  TENANCY STATEMENT.

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

     16.2  If Lessor desires to finance, refinance, or sell the Premises, any
part thereof, or  the building of which the Premises are a part, Lessee and all
Guarantors of Lessee's performance hereunder shall deliver to any potential
lender or purchaser designated by Lessor such financial statements of Lessee and
such Guarantors as may be reasonably required by such lender or purchaser,
including but to 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, a 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 charge, not received by Lessor within thirty (30)
days following the date on which it was due, shall bear interest from the
thirty-first (31st) day after it was due at the rate of 12% per annum, but not
exceeding the maximum rate allowed by law, in addition to the late charge
provided for in Paragraph 13.4.

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

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

22.  NO PRIOR OR OTHER AGREEMENTS; BROKER DISCLAIMER.  This Lease contains all
agreements between the Parties with respect to any matter mentioned herein, and
no other prior or contemporaneous agreement or understanding shall be effective.
Lessor and Lessee each represents and warrants to the Brokers that it has

made, and is relying solely upon, its own investigation as to the nature,
quality, character and financial responsibility of the other Party to this Lease
and as to the nature, quality and character of the Premises. Brokers have no
responsibility with respect thereto or with respect to any default or breach
hereof by either Party.

23.  NOTICES.

     23.1  All notices required or permitted by this Lease shall be in writing
and may be delivered in person (by hand or by messenger or courier service) or
may be sent by regular, certified or registered mail or U.S. Postal Service
Express Mail, with postage prepaid, or by facsimile transmission, and shall be
deemed sufficiently given if served in a manner specified in this Paragraph  23.
The addresses noted adjacent to a Party's signature on this Lease shall be that
Party's address for delivery or mailing of notice purposes.  Either Party may be
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 of mail.  If notice is received
on a Sunday or legal holiday, it shall be deemed received on the next business
day.

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

25.  RECORDING.  Either Lessor or Lessee shall, upon request of the other,
execute, acknowledge and deliver to the other a short form memorandum of this
Lease for recording purposes.  The Party requesting recordation shall be
responsible for payment of any fees or taxes applicable thereto.

26.  NO RIGHT TO HOLDOVER.  Lessee has no right to retain possession of the
Premises or any part thereof beyond the expiration or earlier termination of
this Lease; any violation of this provision will entitle Lessor to Base Rent at
125 percent of the then Base Rent and will result in Lessee's being a month-to-
month tenant.  Lessee shall have to abide by all other provisions of this lease,
as well.

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.

     30.3  NON-DISTURBANCE.  With respect to Security Devices entered into by
Lessor after the execution of this Lease, Lessee's subordination of this Lease
shall be subject to receiving assurance (a "non-disturbance agreement") from the
Lender that Lessee's possession and this Lease, including any options to extend
the term hereof, will not be disturbed so long as Lessee is not in Breach hereof
and attorns to the record owner of the Premises.

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

31.  ATTORNEY'S FEES.  If any Party or Broker brings an action or proceeding to
enforce the terms hereof or declare rights hereunder, the Prevailing Party (as
hereafter defined) or Broker in any such proceeding, action, or appeal thereon,
shall be entitled to reasonable attorney's fees.  Such fees may be awarded in
the same suit or recovered in a separate suit, whether or not such action or
proceeding is pursued to decision or judgment.  The term "Prevailing Party"
shall include, without limitation, a Party or Broker who substantially obtains
or defeats the relief sought, as the case may be, whether by compromise,
settlement, judgment, or the abandonment by the 

NET                                                               Initials _____

other Party or Broker of its claim or defense. The attorney's fees award shall
not be computed in accordance with any court fee schedule, but shall be such as
to fully reimburse all attorney's fees reasonably incurred. Lessor shall be
entitled to attorney's fees, costs and expenses incurred in the preparation and
service of notices of Default and consultations in connection therewith, whether
or not a legal action is subsequently commenced in connection with such Default
or resulting Breach.

32.  LESSOR'S ACCESS; SHOWING PREMISES; REPAIRS.  Lessor and Lessor's agents
shall have the right to enter the Premises at any time, in the case of an
emergency and otherwise at reasonable times for the purpose of showing the same
to prospective purchasers, lenders, or lessees (but as to prospective lessees,
only during the last 180 days of the Term), and making such alterations,
repairs, improvements or additions to the Premises or to the building of which
they are a part, as Lessor may reasonably deem necessary.  Lessor may at any
time place on or about the Premises or building any ordinary "For Sale" signs
and Lessor may at any time during the last one hundred twenty (120) days of the
term hereof place on or about the Premises any ordinary "For Lease" signs.  All
such activities of Lessor shall be without abatement of rent or liability to
Lessee.

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

34.  SIGNS.  Lessee shall not place any sign upon the Premises, except that
Lessee may, with Lessor's prior written consent, install (but not on the roof)
such signs as are reasonably required to advertise Lessee's own business.  The
installation of any sign on the Premises by or for Lessee shall be subject to
the provisions of Paragraph 7 (Maintenance, Repairs, Utility Installations,
Trade Fixtures and Alterations).  Unless otherwise expressly agreed herein,
Lessor reserves all rights to the use of the roof and the right to install, and
all revenues from the installation of, such advertising signs on the Premises,
including the 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 acknowledgment that
no Default or Breach by Lessee of this Lease exists, nor shall such consent be
deemed a waiver of any then existing Default or Breach, except as may be
otherwise specifically stated in writing by Lessor at the time of such consent.

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

37.  GUARANTOR.

     37.1  If there are to be any Guarantors of this Lease per Paragraph 1.11,
the form of the guaranty to be executed by each such Guarantor shall be in the
form most recently published by the American Industrial Real Estate Association,
and each said Guarantor shall have the same obligations as Lessee under this
Lease, including but not limited to the obligation to provide the Tenancy
Statement and information called for by Paragraph 16.

such Guarantor fails or refuses, upon reasonable request by Lessor to give:  (a)

including the authority of the Guarantor (and of the party signing on
Guarantor's behalf) to obligate such Guarantor on said guaranty, and including

board of directors authorizing the making of such guaranty, together with a
certificate of incumbency showing the signature of the persons authorized to
sign on its behalf, (b) current financial statements of Guarantor as may from
time to time be requested by Lessor, (c) a Tenancy Statement, or (d) written

or entity other than said original Lessee while the original Lessee is in full
and actual possession of the Premises and without the intention of thereafter

assignable, either as a part of an assignment of this Lease or separately or
apart therefrom, and no Option may be separated from this Lease in any manner,
by reservation or otherwise.

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

     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:  (i) 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

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

effectuate any such easement rights, dedication, map or restrictions.

43.  PERFORMANCE UNDER PROTEST. If at any time a dispute shall arise as to any
amount or sum of money to be paid by one Party to the other under the provisions
hereof, the Party against whom the obligation to pay the money is asserted shall
have the right to make payment "under protest" and such payment shall not be
regarded as a voluntary payment and there shall survive the right on the part of
said Party to institute suite 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.

terms, covenants and conditions set forth in this Lease.  Unless otherwise
provided herein, any statement of square footage set forth in this Lease, or

and Lessee agree is reasonable and the rental based thereon is not subject to
revision whether or not the actual square footage is more or less.

     2.2  CONDITION.  Lessor shall deliver the Premises to Lessee clean and free
of debris on the Commencement Date and warrants to Lessee that the plumbing,

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 (1)year after the Commencement Date,
correction of that non-compliance shall be the obligation of Lessee at Lessee's
sole cost and expense.

     2.3  COMPLIANCE WITH COVENANTS, RESTRICTIONS AND BUILDING CODE.  Lessor
warrants to Lessee that the improvements on the Premises comply with all
applicable covenants or restrictions of record and applicable building codes,
regulations and ordinances in effect on the Commencement Date.  Said warranty

shall, except as otherwise provided in this Lease, promptly after receipt of

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

compliance of the Premises with said warranties.

this Lease are as specified in Paragraph 1.3.

be abated for the period of such early possession.  All other terms of this

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.

     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

liability therefor, nor shall such failure affect the validity of this Lease, or
the obligations of Lessee hereunder.

charges, as the same may be adjusted from time to time, to be received by Lessor

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

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 within five (5) business days give a written
notification of same, which notice shall include an explanation of Lessor's
reasonable objections to the change in use.

     6.2  HAZARDOUS SUBSTANCES.

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

                                                                 Initials ______
                                                                          ______

installation (and removal on or before lease expiration or earlier termination)
of reasonably necessary protective modifications to the Premises (such as
concrete easements) and/or the deposit of an additional Security Deposit under
Paragraph 5 hereof.

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

          (c) INDEMNIFICATION.  Lessee 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* or caused to be brought to the Premises
by or for the Lessee.  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.

          * or caused to be brought to onto

     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, or under 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 

                                                                 Initials ______
                                                                          ______

                                       5

any threatened or actual claim, notice, citation, warning, complaint or report
pertaining to or involving failure by Lessee or the Premises to comply with any
Applicable Law.

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

7.   MAINTENANCE; REPAIRS; UTILITY INSTALLATIONS; TRADE FIXTURES AND
     ALTERATIONS.

     7.1  LESSEE'S OBLIGATIONS.

          (a) Subject to the provisions of Paragraphs 2.2 (Lessor's warranty as
to condition), 2.3 (Lessor's warranty as to compliance with covenants, etc.),
7.2 (Lessor's obligations to repair), 9 (damage and destruction), and 14
(condemnation), Lessee shall, at Lessee's sole cost and expense and at all times
keep the Premises and every part thereof in good order, condition and repair
(non-structural) (whether or not such portion of the Premises requiring repairs,
or the means of repairing the same, are reasonably or readily accessible to
Lessee, and whether or not the need for such repairs occurs as a result of
Lessee's use, any prior use, the elements or the age of such portion of the
Premises), including, without limiting the generality of the foregoing all
equipment or facilities serving the Premises, such as plumbing, heating, air
conditioning, ventilating, electrical, lighting facilities, boilers, fired or
unfired pressure vessels, fire sprinkler and/or standpipe and hose or other
automatic fire extinguishing system, including fire alarm and/or smoke detection
systems and equipment, fixtures, walls (interior), ceilings, windows, doors,
plate glass, skylights, signs, & elevator (but only such items as are inside the
building,) located in, on, about, or adjacent to the Premises.  Lessee shall not
cause or permit any Hazardous Substance to be spilled or released in, on, under
or about the Premises (including through the plumbing or sanitary sewer system)
and shall promptly, at Lessee's expense, take all investigatory and/or remedial
action reasonably recommended, whether or not formally ordered or required, for
the cleanup of any contamination of, and for the maintenance, security and/or
monitoring of the Premises, elements surrounding same, or neighboring
properties, that was caused or materially contributed to by Lessee, or
pertaining to or involving any Hazardous Substance and/or storage tank brought
into the Premises by or for Lessee or under its control.  Lessee, in keeping the
Premises in good order, condition and repair, shall exercise and perform good
maintenance practices.  Lessee's obligations shall include restorations,
replacements or renewals when necessary to keep the Premises and all
improvements thereon or a part thereof in good order, condition and state of
repair.  If Lessee occupies the Premises for seven (7) years or more, Lessor may
require Lessee to repaint the exterior of the buildings on the Premises 

                                                                 Initials ______
                                                                          ______

                                       6

as reasonably required, but not more frequently than once every seven (7) years.
Additionally, to the extent Lessor benefits from recovery on any extended
warranties or legal actions regarding defects in the items Lessee is required to
maintain and replace under this paragraph, Lessor will reimburse Lessee or
relieve it of its.

          (b) Lessee shall, at Lessee's sole cost and expense, procure and
maintain contracts, with copies to Lessor, in customary form and substance for,
and with contractors specializing and experienced in, the inspection,
maintenance and service of the following equipment and improvements, if any,
located on the Premises:  (i) heating, air conditioning and ventilation
equipment, (ii) boiler, fired or unfired pressure vessels, (iii) fire sprinkler
and/or standpipe and hose or other automatic fire extinguishing systems,
including fire alarm and/or smoke detection, elevator repair, maintenance &
inspections.

     7.2  LESSOR'S OBLIGATIONS.  Except for the warranties and agreements of
Lessor contained in Paragraphs 2.2 (relating to condition of the Premises), 2.3
(relating to compliance with covenants, restrictions and building code), 9
(relating to destruction of the Premises) and 14 (relating to condemnation of
the Premises), it is intended by the Parties hereto that Lessor have no
obligation, in any manner whatsoever, to repair and maintain the Premises, the
improvements located thereon, or the equipment therein, whether structural or
non structural, all of which obligations are intended to be that of the Lessee
under Paragraph 7.1 hereof.  It is the intention of the Parties that the terms
of this Lease govern the respective obligations of the Parties as to maintenance
and repair of the Premises.  Lessee and Lessor expressly waive the benefit of
any statute now or hereafter in effect to the extent it is inconsistent with the
terms of this Lease with respect to, or which affords Lessee the right to make
repairs at the expense of Lessor or to terminate this Lease by reason of any
needed repairs.

     7.3  UTILITY INSTALLATIONS; TRADE FIXTURES; ALTERATIONS.

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

          (b) CONSENT.  Any Alterations or Utility Installations that Lessee
shall desire to make and which require the consent of the Lessor shall be
presented to Lessor in written form with 

                                                                 Initials ______
                                                                          ______

                                       7
<PAGE>
 
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 Alternation or Utility Installation to
Lessor prior to commencement of the work thereon, and (iii) the compliance by
Lessee with all conditions of said permits in a prompt and expeditious manner.
Any alternations or Utility Installations by Lessee during the term of this
Lease shall be done in a good and workmanlike manner, with good and sufficient
materials, and in compliance with all Applicable Law. Lessee shall promptly upon
completion thereof furnish Lessor with as-built plans and specifications
therefor. Lessor may (but without obligation to do so) condition its consent to
any requested Alteration or Utility Installation that costs $10,000 or more upon
Lessee's providing Lessor with a lien and completion bond in an amount equal to
one and one-half times the estimated cost of such Alteration or Utility
Installation.

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

     7.4  OWNERSHIP; REMOVAL; SURRENDER; AND RESTORATION.

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

          (b) REMOVAL.  Unless otherwise agreed in writing, Lessor may require
that any or all Lessee Owned Alterations or Utility Installations be removed by
the expiration or earlier termination of this Lease, notwithstanding their
installation may have been consented to by Lessor.  Lessor may require the
removal at any time of all or any part of any Lessee Owned Alterations or
Utility Installations made without the required consent of Lessor.

                                                                 Initials ______
                                                                          ______

          (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 this 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 Alternations 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.  Lessee's 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 $2,000,000 per occurrence.  Premiums for policy
periods commencing prior to or extending beyond the Lease term shall be prorated
to correspond to the Lease term.  Payment shall be made by Lessee to Lessor
within ten (10) days following receipt of an invoice 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 $2,000,000 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 insurance 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 shall also maintain liability insurance described in Paragraph 8.2(a),
above, in addition to, and not in lieu of, the insurance required to be
maintained by Lessee.  Lessee shall not be named as an additional insured
therein.

                                                                 Initials ______
                                                                          ______

     8.3  PROPERTY INSURANCE - BUILDING, IMPROVEMENTS AND RENTAL VALUE.

          (a) BUILDING AND IMPROVEMENTS.  The Insuring Party (as defined in
Section 1.9 above, Lessor) 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,
but in no event more than the commercially reasonable and available insurable
value thereof if, by reason of the unique nature or age of the improvements
involved, such latter amount is less than full replacement cost.  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, including
coverage for any additional costs resulting from debris removal and reasonable
amounts of coverage for the enforcement of any ordinance or law regulating the
reconstruction or replacement of any undamaged sections of the Premises required
to be demolished or removed by reason of the enforcement of any building,
zoning, safety or land use laws as the result of a covered cause of loss.  Said
policy or policies shall also contain an agreed valuation provision in lieu of
any coinsurance clause, waiver of subrogation, and inflation guard protection
causing an increase in the annual property insurance coverage amount by a factor
of not less than the adjusted U.S. Department of Labor Consumer Price Index for
All Urban Consumers for the city nearest to where the Premises are located.  If
such insurance coverage has a deductible clause, the deductible amount shall not
exceed $1,000 per occurrence, and Lessee shall be liable for such deductible
amount in the event of an Insured Loss, as defined in Paragraph 9.1(c).

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

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

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

                                                                 Initials ______
                                                                          ______

                                       10
<PAGE>
 
Party, the policy carried by Lessee under this Paragraph 8.3 shall insure Lessee
Owned Alterations and Utility Installations.

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

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

     8.7  INDEMNITY.  Except for Lessor's negligence and/or breach of express
warranties, Lessee shall indemnify, protect, defend and hold harmless the
Premises, Lessor and its agents, Lessor's master or ground lessor, partners and
Lenders, from and against any and all claims, loss of rents and/or damages,
costs, liens, judgments, penalties, permits, attorney's and consultant's fees,
expenses and/or liabilities arising out of, involving, or in dealing with
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 

                                                                 Initials ______
                                                                          ______

                                       11

reduced to judgment, and whether well founded or not. In case any action or
proceeding be brought against Lessor by reason of any of the foregoing matters,
Lessee upon notice from Lessor shall defend the same at Lessee's expense by
counsel reasonably satisfactory to Lessor and Lessor shall cooperate with Lessee
in such defense. Lessor need not have first paid any such claim in order to be
so indemnified.

     8.8.  EXEMPTION OF LESSOR FROM LIABILITY.  Except for Lessor's negligence
and/or breach of express warranties, 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 Lessors' negligence or breach of
this Lease, Lessor shall under no circumstances be liable for injury to Lessee's
business or for any loss of income or profit therefrom.

9.   DAMAGE OR DESTRUCTION.

     9.1  DEFINITIONS.

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

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

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

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

                                                                 Initials ______
                                                                          ______

                                       12
<PAGE>
 
          (e) "HAZARDOUS SUBSTANCE CONDITION" shall mean the occurrence or
discovery of a condition involving the presence of, or a contamination by, a
Hazardous Substance as defined in Paragraph 6.2(a), in, on, or under the
Premises.

     9.2  PARTIAL DAMAGE - INSURED LOSS.  If a Premises Partial Damage that is
an Insured Loss occurs, then Lessor shall, at Lessor's expense, repair such
damage (but not Lessee's Trade Fixtures or Lessee Owned Alterations and Utility
Installations) as soon as reasonably possible and this Lease shall continue in
full force and effect; provided, however, that Lessee shall, at Lessor's
election, make the repair of any damage or destruction the total cost to repair
of which is $10,000 or less, and, in such event, Lessor shall make the insurance
proceeds available to Lessee on a reasonable basis for that purpose.
Notwithstanding the foregoing, if the required insurance was not in force or the
insurance proceeds are not sufficient to effect such repair, the Insuring Party
shall promptly contribute the shortage in proceeds (except as to the deductible
which is Lessee's responsibility) as and when required to complete said repairs.
In the event, however, the shortage in proceeds was due to the fact that, by
reason of the unique nature of the improvements, full replacement cost insurance
coverage was not commercially reasonable and available, Lessor shall have no
obligation to pay for the shortage in insurance proceeds or to fully restore the
unique aspects of the Premises unless Lessee provides Lessor with the funds to
cover same, or adequate assurance thereof, within ten (10) days following
receipt of written notice of such shortage and request therefor.  If Lessor
receives said funds or adequate assurance thereof within said ten (10) day
period, the party responsible for making the repairs shall complete them as soon
as reasonably possible and this Lease shall remain in full force and effect.  If
Lessor does not receive such funds or assurance within said period, Lessor may
nevertheless elect by written notice to Lessee within ten (10) days thereafter
to make such restoration and repair as is commercially reasonable with Lessor
paying any shortage in proceeds, in which case this Lease shall remain in full
force and effect.  If in such case Lessor does not so elect, then this Lease
shall terminate sixty (60) days following the occurrence of the damage or
destruction.  Unless otherwise agreed, Lessee shall in no event have any right
to reimbursement from Lessor for any funds contributed by Lessee to repair any
such damage or destruction.  Premises Partial Damage due to flood or earthquake
shall be subject to Paragraph 9.3 rather than 9.2, notwithstanding that there
may be some insurance coverage, but the net proceeds of any such insurance shall
be made available for the repairs if made by either Party.

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

                                                                 Initials ______
                                                                          ______

                                       13
<PAGE>
 
required funds are available. If Lessee does not give such notice and provide
the funds of assurance thereof within the times specified above, this Lease
shall terminate as of the date specified in Lessor's notice of termination.

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

     9.5  DAMAGE NEAR END OF TERM.  If at any time during the last six (6)
months of the term of this Lease there is damage for which the cost to repair
exceeds one (1) month's Base Rent, whether or not an Insured Loss, Lessor may,
at Lessor's option, terminate this Lease effective sixty (60) days following the
date of occurrence of such damage by giving written notice to Lessee of Lessor's
election to do so within thirty (30) days after the date of occurrence of such
damage.  Provided, however, if Lessee at that time has an exercisable option to
extend this Lease or to purchase the Premises, then Lessee may preserve this
Lease by, within twenty (20) days following the occurrence of the damage, or
before the expiration of the time provided in such option for its exercise,
whichever is earlier ("Exercise Price"), (i) exercising such option and (ii)
providing Lessor with any shortage in insurance proceeds (or adequate assurance
thereof) needed to make the repairs.  If Lessee duly exercises such option
during said Exercise Period and provides Lessor with funds (or adequate
assurance thereof) to cover any shortage in insurance proceeds, Lessor shall, at
Lessor's expense repair such damage as soon as reasonably possible and this
Lease shall continue in full force and effect.  If Lessee fails to exercise such
option and provide such funds or assurance during said Exercise Period, then
Lessor may at Lessor's option terminate this Lease as of the expiration of said
sixty (60) day period following the occurrence of such damage by giving written
notice to Lessee of Lessor's election to do so within ten (10) days after the
expiration of the Exercise Period, notwithstanding any term or provision in the
grant of option to the contrary.

     9.6  ABATEMENT OF RENT, LESSEE'S REMEDIES.

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

          (b) If Lessor shall be obligated to repair or restore the Premises
under the provisions of this Paragraph 9, Lessor shall commence, in a
substantial and meaningful way, the repair or restoration of the Premises within
thirty (30) days after such obligation shall accrue.  If 

                                                                 Initials ______
                                                                          ______

                                       14
<PAGE>
 
Lessor does not so repair such damages, Lessee may, give written notice to
Lessor and to any Lenders of which Lessee has actual notice of Lessee's election
to terminate this Lease. "Commence" as used in this Paragraph shall mean either
the unconditional authorization of the preparation of the required plans, or the
beginning of the actual work on the Premises, whichever first occurs.

     9.7  HAZARDOUS SUBSTANCE CONDITIONS.  If a Hazardous Substance Condition
occurs, unless Lessee is legally responsible therefor (in which case Lessee
shall make the investigation and remediation thereof required by Applicable Law
and this Lease shall continue in full force and effect, but subject to Lessor's
rights under Paragraph 13), Lessor may at Lessor's option either (i) investigate
and remediate such Hazardous Substance Condition, if required, as soon as
reasonably possible at Lessor's expense, in which event this Lease shall
continue in full force and effect, or (ii) if the estimated cost to investigate
and remediate such condition exceeds twelve (12) times the then monthly Base
Rent or $100,000, whichever is greater, give written notice to Lessee within
thirty (30) days after receipt by Lessor of knowledge of the occurrence of such
Hazardous Substance Condition of Lessor's desire to terminate this Lease as of
the date sixty (60) days following the giving of such notice.  In the event
Lessor elects to give such notice of Lessor's intention to terminate this Lease.
Lessee shall have the right within ten (10) days after the receipt of such
notice to give written notice to Lessor or Lessee's commitment to pay for the
investigation and remediation of such Hazardous Substance Condition totally at
Lessee's expense and without reimbursement from Lessor except to the extent of
an amount equal to twelve (12) times the then monthly Base Rent or $100,000,
whichever is greater.  Lessee shall provide Lessor with the funds required of
Lessee or satisfactory assurance thereof within thirty (30) days following
Lessee's said commitment.  In such event this Lease shall continue in full force
and effect, and Lessor shall proceed to make such investigation and remediation
as soon as reasonably possible and the required funds are available.  If Lessee
does not give such notice and provide the required funds or assurance thereof
within the times specified above, this Lease shall terminate as of the date
specified in Lessor's notice of termination.  If a Hazardous Substance Condition
occurs for which Lessee is not legally responsible, there shall be abatement of
Lessee's obligations under this Lease to the same extent as provided in
Paragraph 9.6(a) for a period of not to exceed twelve (12) months.

     9.8  TERMINATION - ADVANCE PAYMENTS.  Upon termination of this Lease
pursuant to this Paragraph 9, an equitable adjustment shall be made concerning
advance Base Rent and any other advance payments made by Lessee to Lessor.
Lessor shall, in addition, return to Lessee so much of Lessee's Security Deposit
as has not been, or is not then required to be, used by Lessor under the terms
of this Lease.

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

10.  REAL PROPERTY TAXES.
     ------------------- 

     10.1  (a)  PAYMENT OF TAXES.  Lessee shall pay the Real Property Taxes, as
defined in Paragraph 10.2, applicable to the Premises during the term of this
Lease; provided, however, that for the first five (5) years of the term, Lessee
shall not incur the burden of any increase in taxes that results from a
transfer, sale, or refinance of the Premises.  Subject to Paragraph 10.1(b), all
such 

                                                                 Initials ______
                                                                          ______

                                       15
<PAGE>
 
payments shall be made at least ten (10) days prior to the delinquency date of
the applicable installment. Lessee shall promptly furnish Lessor with
satisfactory evidence that such taxes have been paid. If any such taxes to be
paid by Lessee shall cover any period of time prior to or after the expiration
or earlier termination of the term hereof, Lessee's share of such taxes shall be
equitably prorated to cover only the period of time within the tax fiscal year
this Lease is in effect, and Lessor shall reimburse Lessee for any overpayment
after such proration. If Lessee shall fail to pay any Real Property Taxes
required by this Lease to be paid by Lessee, Lessor shall have the right to pay
the same, and Lessee shall reimburse Lessor therefor upon demand.

          (b) ADVANCE PAYMENT.  In order to insure payment when due and before
delinquency of any or all Real Property Taxes, Lessor reserves the right, at
Lessor's option, to estimate the current Real Property Taxes applicable to the
Premises, and to require such current year's Real Property Taxes to be paid in
advance to Lessor by Lessee, either:  (i) in a lump sum equal to the installment
due, at least twenty (20) days prior to the applicable delinquency date, or (ii)
monthly in advance with the payment of the Base Rent.  If Lessor elects to
require payment monthly in advance, the monthly payment shall be that equal
amount which, over the number of months remaining before the month in which the
applicable tax installment would become delinquent (and without interest
thereon), would provide a fund large enough to fully discharge before
delinquency the estimated installment of taxes to be paid.  When the actual
amount of the applicable tax bill is known, the amount of such equal monthly
advance payment shall be adjusted as required to provide the fund needed to pay
the applicable taxes before delinquency.  If the amounts paid to Lessor by
Lessee under the provisions of this Paragraph are insufficient to discharge the
obligations of Lessee to pay such Real Property Taxes as the same become due,
Lessee shall pay to Lessor upon Lessor's demand, such additional sums as are
necessary to pay such obligations.  All moneys paid to lessor under this
Paragraph may be intermingled with other moneys of Lessor and shall not bear
interest.  In the event of a Breach by Lessee in the performance of the
obligations of Lessee under this Lease, then any balance of funds paid to Lessor
under the provisions of this Paragraph may, subject to proration as provided in
Paragraph 10.1(a), at the option of Lessor, be treated as an additional Security
Deposit under Paragraph 5.

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

     10.3  JOINT ASSESSMENT.  If the Premises are not separately assessed,
Lessee's liability shall be an equitable proportion of the Real Property Taxes
for all of the land and improvements included 

                                                                 Initials ______
                                                                          ______

                                       16
<PAGE>
 
within the tax parcel assessed, such proportion to be determined by Lessor from
the respective valuations assigned in the assessor's work sheets or such other
information as may be reasonably available. Lessor's reasonable determination
thereof, in good faith, shall be conclusive.

     10.4  PERSONAL PROPERTY TAXES.  Lessee shall pay prior to delinquency all
taxes assessed against and levied upon Lessee Owned Alterations, Utility
Installations, Trade Fixtures, furnishings, equipment and all personal property
of Lessee contained in the Premises or elsewhere.  When possible, Lessee shall
cause its Trade Fixtures, furnishings, equipment and all other personal property
to be assessed and billed separately from the real property of Lessor.  If any
of 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
reasonably 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.

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

           (d) An assignment or subletting of Lessee's interest in this Lease
without Lessor's specific prior written consent shall, at Lessor's option, be a
Default curable after notice per Paragraph 13.1(c), or a noncurable Breach
without the necessity of any notice and grace period.  If Lessor elects to treat
such unconsented to assignment or subletting as a noncurable Breach, Lessor
shall have the right to either:  (i) terminate this Lease, or (ii) upon thirty
(30) days written notice ("Lessor's Notice"), increase the monthly Base Rent to
fair market rental value or one hundred ten percent 

                                                                 Initials ______
                                                                          ______

                                       17
<PAGE>
 
(110%) of the Base Rent then in effect, whichever is greater. Pending
determination of the new fair market rental value, if disputed by Lessee, Lessee
shall pay the amount set forth in Lessor's Notice, with any overpayment credited
against the next installment(s) of Base Rent coming due, and any underpayment
for the period retroactively to the effective date of the adjustment being due
and payable immediately upon the determination thereof. Further, in the event of
such Breach and market value adjustment, (i) the purchase price of any option to
purchase the Premises held by Lessee shall be subject to similar adjustment to
the then fair market value (without the Lease being considered an encumbrance or
any deduction for depreciation or obsolescence, and considering the Premises at
its highest and best use and in good condition), or one hundred ten percent
(110%) of the price previously in effect, whichever is greater, (ii) any index-
oriented rental or price adjustment formulas contained in this Lease shall be
adjusted to require that the base index be determined with reference to the
index applicable to the time of such adjustment, and (iii) any fixed rental
adjustments scheduled during the remainder of the Lease term shall be increased
in the same ratio as the new market rental bears to the Base Rent in effect
immediately prior to the market value adjustment.

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

     12.2  TERMS AND CONDITIONS APPLICABLE TO ASSIGNMENT AND SUBLETTING.

           (a) Regardless of Lessor's consent, any assignment of 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) after 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.

           (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 

                                                                 Initials ______
                                                                          ______

the intended use and/or required modification of the Premises, if any. 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 confirm and comply with each
and every term, covenant, condition and obligation herein to be observed or
performed by Lessee during the term of said assignment or sublease, other than
such obligations as are contrary to or inconsistent with provisions of an
assignment or sublease to which Lessor has specifically consented in writing.

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

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

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

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

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

                                                                 Initials ______
                                                                          ______

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

13.  DEFAULT; BREACH; REMEDIES.

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

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

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

           (c) Except as expressly otherwise provided in this Lease, the failure
by Lessee to provide Lessor with reasonable written evidence (in duly executed
original form, if applicable) of (i) compliance with Applicable Law per
Paragraph 6.3, (ii) the inspection, maintenance and service contracts required
under Paragraph 7.1(b), (iii) the 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 ten (10) days
following written notice by or on behalf of Lessor to Lessee.

           (d) A Default by Lessee as to the terms, covenants, conditions or
provisions of this Lease, or of the rules adopted under Paragraph 40 hereof,
that are to be observed, complied with or performed by Lessee, other than those
described in subparagraphs (a), (b) or (c), above, where such Default continues
for a period of thirty (30) days after written notice thereof by or on behalf of
Lessor to Lessee; provided, however, that if the nature of Lessee's Default is
such that more than 

                                                                 Initials ______
                                                                          ______

                                       20
<PAGE>
 
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. (S)101 or any
successor statute thereto (unless, in the case of a petition filed against
Lessee, the same is dismissed within sixty (60) days); (iii) the appointment of
a trustee or receiver to take possession of substantially all of Lessee's assets
located at the Premises or of Lessee's interest in this Lease, where possession
is not restored to Lessee within thirty (30) days; or (iv) the attachment,
execution or other judicial seizure of substantially all of Lessee's assets
located at the Premises or of Lessee's interest in this Lease, where such
seizure is not discharged within thirty (30) days; provided, however, in the
event that any provision of this subparagraph (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 insolvent or the subject of a
bankruptcy filing, (iv) a guarantor's refusal to honor the guaranty, or (v) a
guarantor's breach of its guaranty obligation on an anticipatory breach basis,
and Lessee's failure, within sixty (60) days following written notice by or on
behalf of Lessor to Lessee of any such event, to provide Lessor with written
alternative assurance or security, which, when coupled with the then existing
resources of Lessee, equals or exceeds the combined financial resources of
Lessee and the guarantors that existed at the time of execution of this Lease.

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

           (a) Terminate Lessee's right to possession of the Premises by any
lawful means, in which case this Lease and the term hereof shall terminate and
Lessee shall immediately surrender possession of the Premises to Lessor.  In
such event Lessor shall be entitled to recover from Lessee:  (i) the worth at
the time of the award of the unpaid rent which had been earned at the time of
termination; (ii) the worth at the time of award of the amount by which the
unpaid rent which would 

                                                                 Initials ______
                                                                          ______

                                       21
<PAGE>
 
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 two such grace periods shall
constitute both an unlawful detainer and a Breach of this Lease entitling Lessor
to the remedies provided for in this Lease and/or by said statute.

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

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

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

     13.3  INDUCEMENT RECAPTURE IN EVENT OF BREACH.  Any agreement by Lessor for
free or abated rent or other charges applicable to the Premises, or for the
giving or paying by Lessor to or for Lessee of any cash or other bonus,
inducement or consideration for Lessee's entering into this Lease, all of which
concessions are hereinafter referred to as "Inducement Provisions," shall be
deemed 

                                                                 Initials ______
                                                                          ______

                                       22
<PAGE>
 
conditioned upon Lessee's full and faithful performance of all of the terms,
covenants and conditions of this Lease to be performed or observed by Lessee
during the term hereof as the same may be extended. Upon the occurrence of a
Breach of this Lease by Lessee, as defined in Paragraph 13.1, any such
inducement Provision shall automatically be deemed deleted from this Lease and
of no further force or effect, and any rent, other charge, bonus, inducement or
consideration theretofore abated, given or paid by Lessor under such an
inducement Provision shall be immediately due and payable by Lessee to Lessor,
and recoverable by Lessor as additional rent due under this Lease,
notwithstanding any subsequent cure of said Breach by Lessee. The acceptance by
Lessor of rent or the cure of the Breach which initiated the operation of this
Paragraph shall not be deemed a waiver by Lessor of the provisions of this
Paragraph unless specifically so stated in writing by Lessor at the time of such
acceptance.

     13.4  LATE CHARGES.  Lessee hereby acknowledges that late payment by Lessee
to Lessor of rent and other sums due hereunder will cause Lessor to incur costs
not contemplated by this Lease, the exact amount of which will be extremely
difficult to ascertain.  Such costs include, but are not limited to, processing
and accounting charges, and late charges which may be imposed upon Lessor by the
terms of any ground lease, mortgage or trust deed covering the Premises.
Accordingly, if any installment of rent or any other sum due from Lessee shall
not be received by Lessor or Lessor's designee within seven (7) 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 two percent (2%) of such overdue
amount.  The parties hereby agree that such late charge represents a fair and
reasonable estimate of the costs Lessor will incur by reason of late payment by
Lessee.  Acceptance of such late charge by Lessor shall in no event constitute a
waiver of Lessee's Default or Breach with respect to such overdue amount, nor
prevent Lessor from exercising any of the other rights and remedies granted
hereunder.  In the event that a late charge is payable hereunder, whether or not
collected, for three (3) consecutive installments of Base Rent, than
notwithstanding Paragraph 4.1 or any other provision of this Lease to the
contrary, Base Rent shall, at Lessor's option, become due and payable quarterly
in advance.

     13.5  BREACH BY LESSOR.  Lessor shall not be deemed in breach of this Lease
unless Lessor fails within a reasonable time to perform an obligation required
to be performed by Lessor.  For purposes of this Paragraph 13.5, a reasonable
time shall in no event be less than thirty (30) days after receipt by Lessor,
and by the holders of any ground lease, mortgage or deed of trust covering the
Premises whose name and address shall have been furnished Lessee in writing for
such purpose, of written notice specifying wherein such obligation of Lessor had
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.

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 title or
possession, whichever first occurs.  If more than ten percent (10%) of the floor
areas of the Premises, or more than twenty-five percent (25%) of the land area
not occupied by any building, is taken by condemnation, Lessee may, at Lessee's
option, to be exercised in writing within 

                                                                 Initials ______
                                                                          ______

                                       23
<PAGE>
 
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  The Brokers named in Paragraph 1.10 are the only Brokers involved in
this Lease.

     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  Lessor and Lessee hereby consent to and approve all agency
relationships, including any dual agencies, indicated in Paragraph 1.10.

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.

                                                                 Initials ______
                                                                          ______

                                       24
<PAGE>
 
     16.2  If Lessor desires to finance, refinance, or sell the Premises, any
part thereof, or the building of which the Premises are a part, Lessee and all
Guarantors of Lessee's performance hereunder shall deliver to any potential
lender or purchaser designated by Lessor such financial statements of Lessee and
such Guarantors as may be reasonably required by such lender or purchaser,
including but to 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, a determined
by a court of competent jurisdiction, shall in no way affect the validity of any
other provision hereof.

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

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

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

22.  NO PRIOR OR OTHER AGREEMENTS; BROKER DISCLAIMER.  This Lease contains all
agreements between the Parties with respect to any matter mentioned herein, and
no other prior or contemporaneous agreement or understanding shall be effective.
Lessor and Lessee each represents and warrants to the Brokers that it has made,
and is relying solely upon, its own investigation as to the nature, quality,
character and financial responsibility of the other Party to this Lease and as
to the nature, quality and character of the Premises.  Brokers have no
responsibility with respect thereto or with respect to any default or breach
hereof by either Party.

23.  NOTICES.

     23.1  All notices required or permitted by this Lease shall be in writing
and may be delivered in person (by hand or by messenger or courier service) or
may be sent by regular, certified or registered mail or U.S. Postal Service
Express Mail, with postage prepaid, or by facsimile 

                                                                 Initials ______
                                                                          ______

transmission, and shall be deemed sufficiently given if served in a manner
specified in this Paragraph 23. The addresses noted adjacent to a Party's
signature on this Lease shall be that Party's address for delivery or mailing of
notice purposes. Either Party may by written notice to the other specify a
different address for notice purposes, except that upon Lessee's taking
possession of the Premises, the Premises shall constitute Lessee's address for
the purpose of mailing or delivering notices to Lessee. A copy of all notices
required or permitted to be given to Lessor hereunder shall be concurrently
transmitted to such party or parties at such addresses as Lessor may from time
to time hereafter designate by written notice to Lessee.

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

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

25.  RECORDING.  Either Lessor or Lessee shall, upon request of the other,
execute, acknowledge and deliver to the other a short form memorandum of this
Lease for recording purposes.  The Party requesting recordation shall be
responsible for payment of any fees or taxes applicable thereto.

26.  NO RIGHT TO HOLDOVER.  Lessee has no right to retain possession of the
Premises or any part thereof beyond the expiration or earlier termination of
this Lease; any violation of this provision will entitle Lessor to Base Rent at
125 percent of the then Base Rent and will result in Lessee's being a month-to-
month tenant.  Lessee shall have to abide by all other provisions of this lease,
as well.

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.

                                                                 Initials ______
                                                                          ______

<PAGE>
 
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.

     30.3  NON-DISTURBANCE.  With respect to Security Devices entered into by
Lessor after the execution of this Lease, Lessee's subordination of this Lease
shall be subject to receiving assurance (a "non-disturbance agreement") from the
Lender that Lessee's possession and this Lease, including any options to extend
the term hereof, will not be disturbed so long as Lessee is not in Breach hereof
and attorns to the record owner of the Premises.

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

31.  ATTORNEY'S FEES.  If any Party or Broker brings an action or proceeding to
enforce the terms hereof or declare rights hereunder, the Prevailing Party (as
hereafter defined) or Broker in any such 

                                                                 Initials ______
                                                                          ______

                                       27
<PAGE>
 
proceeding, action, or appeal thereon, shall be entitled to reasonable
attorney's fees. Such fees may be awarded in the same suit or recovered in a
separate suit, whether or not such action or proceeding is pursued to decision
or judgment. The term, "Prevailing Party" shall include, without limitation, a
Party or Broker who substantially obtains or defeats the relief sought, as the
case may be, whether by compromise, settlement, judgment, or the abandonment by
the other Party or Broker of its claim or defense. The attorney's fees award
shall not be computed in accordance with any court fee schedule, but shall be
such as to fully reimburse all attorney's fees reasonably incurred. Lessor shall
be entitled to attorney's fees, costs and expenses incurred in the preparation
and service of notices of Default and consultations in connection therewith,
whether or not a legal action is subsequently commenced in connection with such
Default or resulting Breach.

32.  LESSOR'S ACCESS; SHOWING PREMISES; REPAIRS.  Lessor and Lessor's agents
shall have the right to enter the Premises at any time, in the case of an
emergency, and otherwise at reasonable times for the purposes of showing the
same to prospective purchasers, lenders, or lessees*, and making such
alterations, repairs, improvements or additions to the Premises or to the
building of which they are a part, as Lessor may reasonably deem necessary.
Lessor may at any time place on or about the Premises or building any ordinary
"For Sale" signs and Lessor may at any time during the last one hundred twenty
(120) days of the term hereof place on or about the Premises any ordinary "For
Lease" signs.  All such activities of Lessor shall be without abatement of rent
or liability to Lessee.  *(but as to prospective lessees during the last 180
days of the Term.)

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

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

                                                                 Initials ______
                                                                          ______

36.  CONSENTS.

          (a) Except for Paragraph 33 hereof (Auctions) or as otherwise provided
herein, wherever in this Lease the consent of a Party is required to an act by
or for the other Party, such consent shall not be unreasonably withheld or
delayed.  Lessor's actual reasonable costs and expenses (including but not
limited to architects', attorneys', engineers' or other consultants' fees)
incurred in the consideration of, or response to, a request by Lessee for any
Lessor consent pertaining to this Lease or the Premises, including but not
limited to consents to an assignment, a subletting or the presence or use of a
Hazardous Substance, practice or storage tank, shall be paid by Lessee to Lessor
upon receipt of an invoice and supporting documentation therefor.  Subject to
Paragraph 12.2(e) (applicable to assignment or subletting), Lessor may, as a
condition to considering any such request by Lessee, require that Lessee deposit
with Lessor an amount of money (in addition to the Security Deposit held under
Paragraph 5) reasonably calculated by Lessor to represent the cost Lessor will
incur in considering and responding to Lessee's request.  Except as otherwise
provided, any unused portion of said deposit shall be refunded to Lessee without
interest.  Lessor's consent to any act, assignment of this Lease or subletting
of the Premises by Lessee shall not constitute an acknowledgment that no Default
or Breach by Lessee of this Lease exists, nor shall such consent be deemed a
waiver or 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  If there are to be any Guarantors of this Lease per Paragraph 1.11,
the form of the guaranty to be executed by each such Guarantor shall be in the
form most recently published by the American Industrial Real Estate Association,
and each said Guarantor shall have the same obligations as Lessee under this
Lease, including but not limited to the obligation to provide the Tenancy
Statement and Information called for by Paragraph 16.

     37.2  It shall constitute a Default of the Lessee under this Lease if any
such Guarantor fails or refuses, upon reasonable request by Lessor to give:  (a)
evidence of the due execution of the guaranty called for by this Lease,
including the authority of the Guarantor (and of the party signing on
Guarantor's behalf) to obligate such Guarantor on said guaranty, and including
in the case of a corporate Guarantor, a certified copy of a resolution of its
board of directors authorizing the making of such guaranty, together with a
certificate of incumbency showing the signature of the persons authorized to
sign on its behalf, (b) current financial statements of Guarantor as may from
time to time be requested Lessor, (c) a Tenancy Statement, or (d) written
confirmation that the guaranty is still in effect.

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 

                                                                 Initials ______
                                                                          ______

                                       29

and performed under this Lease, Lessee shall have quiet possession of the
Premises 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 renew
this Lease or to extend or renew any lease that Lessee has on other property of
Lessor; (b) the right of first refusal to lease the Premises or the right of
first offer to lease the Premises or the right of first refusal to lease other
property of Lessor or the right of first offer to lease other property of
Lessor; (c) the right to purchase the Premises, or the right of first refusal to
purchase the Premises, or the right of first offer to purchase the Premises, or
the right to purchase other property of Lessor, or the right of first refusal to
purchase other property of Lessor; or the right of first offer to purchase other
property of Lessor.

     39.2  OPTIONS PERSONAL TO ORIGINAL LESSEE.  Each Option granted to Lessee
in this Lease is personal to the original Lessee named in Paragraph 1.1 hereof,
and cannot be voluntarily or involuntarily assigned or exercised by any person
or entity other than said original Lessee while the original Lessee is in full
and actual possession of the Premises and without the intention of thereafter
assigning or subletting.  The Options, if any, herein granted to Lessee are not
assignable, either as a part of an assignment of this Lease or separately or
apart therefrom, and no Option may be separated from this Lease in any manner,
by reservation or otherwise.

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

     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:  (i) 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 

                                                                 Initials ______
                                                                          ______

                                       30
<PAGE>
 
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.  MULTIPLE BUILDINGS.  If the Premises are part of a group of buildings
controlled by Lessor, Lessee agrees that it will abide by, keep and observe all
reasonable rules and regulations which Lessor may make from time to time for the
management, safety, care, and cleanliness of the grounds, the parking and
unloading of vehicles and the preservation of good order, as well as for the
convenience of other occupants or tenants of such other buildings and their
invitees, and that Lessee will pay its fair share of common expenses incurred in
connection therewith.

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

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

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

                                                                 Initials ______
                                                                          ______

                                       31

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 Multiplied Parties shall be the joint and several
responsibility of all persons or entities named herein as such Lessor 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
