ITEM 1.  BUSINESS

Zamba Corporation ("Zamba" or the "Company") is a consulting and systems
integration company focused exclusively on the customer care market.  Zamba is
committed to improving our clients' ability to care for their customers through
the use of innovative business practices and by leveraging package application
software.  Our services include strategy development, business process alignment
and improvement, systems deployment, and systems support.  Our goal is to assist
our clients in building lasting relationships with their customers, increase the
effectiveness of their customer service and sales operations, and improve
overall communication with their customers. Our customer care services include
the design, implementation and integration of several enterprise level
applications to facilitate sales automation, call center management, marketing
automation, and automated field service and sales.  We offer our clients
end-to-end assistance with their implementations, including business case
evaluation, system planning and design, software implementation, modification
and development, training, installation, change management, network management,
and on-going support.  Typically, we provide our services on a fixed-bid,
fixed-time basis, but we also perform some services on a time-and-expenses
basis.  Under either method, our approach involves a rapid and iterative
methodology that requires significant client involvement. 

Historically, the Company derived a substantial amount of its revenue from sales
of proprietary hardware and software that originally enabled data communication
over specialized mobile radio ("SMR") technology and, eventually, most types of
wireless networks.  During 1996, the Company began a process to expand the
services it could offer to its clients by becoming a systems integrator focused
on wireless data communication and ceased production of its proprietary
hardware.  During 1997, the Company reduced its workforce from approximately 95
employees to approximately 40 employees; consolidated and closed several
facilities; and reduced the carrying value of certain assets no longer expected
to be used in operations.  As a result of these actions, the Company recorded
one-time charges totaling approximately $1.90 million during the third quarter
of 1997.  The Company took these actions because of slower than expected market
and related revenue growth.  Also, during the second half of 1997 and throughout
1998, the Company broadened its sales focus to providing systems integration
services for customer care including Sales Force Automation, Customer Support,
Marketing, Field Service & Sales Automation, and Call Centers.  

In September 1998, the Company completed the acquisition of the QuickSilver
Group, Inc. ("QuickSilver"), a customer care consulting company specializing in
software package implementation for call center management, sales automation,
marketing automation, and automated field service and sales.  This acquisition 
enabled the Company to expand its consulting and systems integration
capabilities and geographic presence.  


                                          2
<PAGE>

In September 1998, the Company also annonuced the formation of NextNet, Inc., by
transferring  its patented "NextNet" wireless data technology to an entity of
the same name, in conjunction with the receipt by that entity of $8 million in
private investment capital to fund the further development of the technology.

THE CUSTOMER CARE MARKET

Customer care is a subset of the package application software market.  Reports
published by Forrester Research project the packaged application software market
to grow at a cumulative average growth rate ("CAGR") of 27%.  Within this
market, the Company's segment is the implementation of packaged application
software for customer care solutions.  The market for customer care
implementation is directly related to software-licensing activities.  The
GartnerGroup anticipates that software-licensing revenue for customer care will
grow at a CAGR of 54%.  The Company estimates that for every $1 of
software-licensing revenue, an additional $1 to $4 is spent on implementation,
training and consulting. 

CUSTOMER CARE...THE ZAMBA APPROACH 

Historically, companies have organized their business processes to ensure
efficient Enterprise Resource Planning. With this model, all front-office
functions that interact with the customer are disconnected, operating as
separate entities. Because the company is not operating as a unified whole with
a single face to the customer, customer confusion and an unsatisfactory customer
experience may result.  Customer care practiced by Zamba helps companies put
their customers at the center of how the company organizes their business
processes and conducts its front office functions. The Zamba model calls for
companies to focus on achieving longer-term customer loyalty rather than only
short-term operational efficiencies. The objective is to give customers what
they deserve: to work with a company that at any given moment understands their
comprehensive history with the company and anticipates their needs.  To
accomplish this radical transformation in customer care, Zamba consultants are
skilled in what the market refers to as front office applications, including
Sales Force Automation, Customer Support, Marketing, Field Service & Sales
Automation, and Call Centers. 

SERVICES

Zamba delivers integrated customer care solutions quickly.  Unlike traditional
consulting firms, which typically focus on customer "management" and measure
success in terms of short-term operational efficiency improvements, Zamba is
focused on deploying integrated customer care solutions and measures success in
terms of longer-term customer loyalty improvements and specific, measurable
business results. 

Zamba offers the following services to its customers:

     OPPORTUNITY ASSESSMENT

     We assess our customers' current customer care performance against our
     Competitive Assessment Model, a comprehensive set of benchmark data from
     industry leaders. Following the assessment, a suggested plan for benefit
     and value realization is developed and delivered.

     BUSINESS CASE DEVELOPMENT

     We provide our customers with a detailed financial and strategic
     quantification of the value and return of the customer care opportunity.

     customers with deploying customer care solutions quickly so they begin to
     receive high-impact business benefits immediately.

     SOLUTION SUPPORT

     Following the deployment of a customer care solution, the Zamba support
     team will provide on-going technical and system support.

          support 

CUSTOMERS

Zamba has a history of working with some of the most competitive, leading-edge
companies in the United States. Our customers have embraced Zamba's
results-oriented approach, reputation, and ability to deliver on-time, on-budget
solutions. 

Zamba has implemented more than 75 customer care solutions for industry-leading
companies such as Ameritech Corporation, Bay Networks, Cisco Systems, 3-Com,
Compaq, Compucom, Hertz, Hewlett-Packard, Honeywell, MCI, Progressive Insurance,
Symbol, Qualcomm, Wang Global and Xerox, among others.

The Company has in the past, and may in the future, derive a significant portion
of its revenue from a relatively small number of clients.  In 1998, two
customers each represented at least 10% of the Company's revenue: Hertz (17.7%)
and Compucom (11.3%). 

SALES AND MARKETING

The Company has a dedicated sales and marketing organization to market and sell
its services. The business development team is chartered with building market
awareness of the Company's offerings, establishing partnerships with the
appropriate hardware, software and consulting vendors, and building a pipeline
of demand for our service solutions.  The organization consists of 8 employees
operating throughout the United States.  At any given time, numerous Zamba
professionals and senior practice leaders are active in the development of new
business.  The coordination of their efforts and tracking of their results is
critical to Zamba's ability to forecast and adequately staff  future work.

COMPETITION

The systems integration market is highly competitive and served by numerous
national, regional and local firms.  The market includes participants from a
variety of market segments, including systems consulting and integration firms,
contract programming companies, application software firms, the professional
services groups of software companies and "Big Five" accounting firms.  Primary
competitors in the customer care market include practices within Technology
Solutions Corporation, Sapient Corporation, and Cambridge Technology Partners. 
The Company also faces competition from information services organizations
within potential clients.  The Company believes 


                                          4
<PAGE>

that the principal competitive factors in the systems integration industry
include technical expertise, responsiveness to client needs, speed in delivering
solutions, quality of service and perceived value. The Company also believes
that its ability to compete depends in part on a number of competitive factors
outside its control, including the ability of its competitors to hire, retain,
and motivate employees, the price at which other companies offer comparable
services, and the extent of its competitors responsiveness to customer needs.

Many of the Company's direct, indirect and potential future competitors have
financial, technical, marketing, sales, distribution and other resources
substantially greater than those of the Company.  Some of these competitors have
established market positions, greater name recognition, substantial
technological capabilities and generate greater consulting revenues than does
the Company.  The Company faces competition not only from these established
companies, but also from start-up companies that have a niche expertise in
specific application technologies.

The competitive environment could adversely affect the Company's business,
results of operations, and financial condition.

EMPLOYEES

The Company's success depends to a significant degree upon the continued
contributions of its key management, sales and technical personnel.  The
Company's success also depends upon its ability to attract and retain highly
qualified personnel.  Competition for such personnel is intense, and there can
be no assurance that the Company will be successful in hiring or retaining
qualified personnel.

As of December 31, 1998, the Company had 95 full-time employees, consisting of
72 individuals in the professional staff, 15 in administrative roles and 8 in
business development. 

The employees and the Company are not parties to any collective bargaining
agreements, and the Company believes that its relations with its employees are
good.

PRODUCT DEVELOPMENT

As noted earlier, Zamba is a systems integration consulting company, and as
such, derives a majority of its revenues from third party products instead of
from sales of its own products.  However, the Company has legacy products from
our years developing wireless mobile data technology.

COMMUNICATIONS SOFTWARE  

The Company's wireless technologies include its KeyWare-Registered Trademark-
middleware technology and other standard commercial software developed by the
Company, such as database interface software, as well as application software
customized by the Company for individual clients.  The Company's technology also
includes certain network management software tools that the Company has
developed in order to identify and diagnose problems arising with clients'
wireless network configurations.

KeyWare was introduced to the market in the first quarter of 1995.  KeyWare is a
wireless networking software product referred to as "middleware," and is built
upon an open client/server architecture. In the third quarter of 1997, the
Company decided to no longer sell KeyWare as a stand-alone product.  Instead,
the Company sells KeyWare only to existing clients. 

OTHER TECHNOLOGY

On September 21, 1998, the Company transferred its patented "NextNet" wireless
data technology to an entity of the same name, in conjunction with the receipt
by that entity of $8 million in private investment capital to fund the further
development of the technology.  In concept, the NextNet technology will enable
high-speed data transmission over existing cellular infrastructures at rates 


                                          5
<PAGE>

not possible with existing systems. The Company received forty-four percent
(44%) ownership of NextNet, the new company, in exchange for the NextNet
technology.  The Company's investment in NextNet is carried at $0, the
historical carrying basis of the technology transferred, as amounts incurred by
the Company up to the date of the transfer were charged to research and
development expense. The fourth quarter of 1998 was the first quarter in which
the Company did not incur expenses related to the development of the NextNet
technology.  Several long-time employees, including two Vice Presidents, of the
Company also transferred to NextNet.  These employees were previously engineers
who worked on KeyWare and our earlier computing devices for SMR.

For the years ended December 31, 1998, 1997, and 1996, the Company's research
and development expenses were approximately $1.16 million, $3.29 million, and
$4.21 million,   respectively. The Company does not expect to have any research
and development costs in 1999, and does expect that clients will directly fund
product enhancements to KeyWare. 

PROPRIETARY RIGHTS

The Company's success is dependent upon its software deployment and consulting
methodologies and other intellectual property rights.  The Company relies upon a
combination of trade secret, nondisclosure and other contractual arrangements
and technical measures, and copyright and trademark laws, to protect its
proprietary rights.  The Company generally enters into confidentiality
agreements with its employees, consultants, clients and potential clients and
limits access to, and distribution of its propriety information.  There can be
no assurance that the steps taken by the Company in this regard will be adequate
to deter misappropriation of its propriety information or that the Company will
be able to detect unauthorized use and take appropriate steps to enforce its
intellectual property rights.

The Company's business includes the development of custom software applications
in connection with specific client engagements.  Ownership of such software is
generally assigned to the client.  In addition, the Company also develops
object-oriented software components that can be reused in software application
development and certain foundation and application software products, or
software "tools," most of which remain the property of the Company.

Although the Company believes that its services and products do not infringe on
the intellectual property rights of others, there can be no assurance that such
a claim will not be asserted against the Company in the future.

YEAR 2000 UPDATE

Year 2000 computer issues create risks for the Company.  The full extent and
scope of such risks have not yet been fully assessed. In the event that internal
products and systems, or those products and systems provided or utilized by
third parties do not correctly recognize and process date data information
beyond the year 1999, material adverse effects on the Company's business,
operating results, and financial condition could result. 

To address Year 2000 issues, the Company has initiated a program designed to
address the most critical Year 2000 items that would affect the Company's
products and the operations of the following functions: operations, finance,
sales, and human resources. The Company has not commenced work on contingency
plans to address potential problems with its internal systems or the systems of
its supplier and customers or other third parties. 

In December 1998, the Company commenced a program to inventory, assess,
remediate, and test the Year 2000 capability of the Zamba software products. All
Zamba Year 2000 activities concerning the Company's current products are
expected to be completed by October 1999. 

Other Year 2000 issues primarily consist of assessing the Year 2000 impact for
outside vendors, customers, and facilities. Project plans are being developed
and will include the process of identifying and prioritizing critical suppliers
and customers at the direct interface level, and 


                                          6
<PAGE>

communicating with them about their plans and progress in addressing Year 2000
issues. Detailed evaluations of the most critical third parties have been
initiated. It is expected that all Year 2000 project plans and 1999 budgets will
be completed by the second quarter of 1999 and the remaining inventories
completed by the end of the second quarter of 1999. This effort will be followed
by each business function conducting a focused level of ranking and functional
assessment of its inventory to establish the methods and actions required to
resolve any Year 2000 issues discovered. The assessment efforts are estimated to
be completed by the second quarter of 1999. The remediation (modification or
replacement of existing software or systems) and the testing phases of the
project plans are expected to take place throughout most of 1999 and are
estimated to be completed, for all business critical items, by the fourth
quarter of 1999. All remaining issues (which are considered low priority or low
risk to the business) are planned to be addressed as time permits and could
continue through the first half of 2000. 

The Company has spent nominal amounts to date and doesn't expect the total cost
associated with required modifications to become Year 2000 ready to be
significant or to have a material adverse effect on the Company's business,
operating results and financial condition. The Company's current estimates of
the amount of time and costs necessary to implement and test its systems are
based on the facts and circumstances existing at this time. New developments may
occur that could affect the Company's estimates for the required modifications
to become Year 2000 ready. These developments include, but are not limited to:
(a) the availability and cost of personnel trained in this area, (b) the ability
to locate and correct all relevant computer code and equipment, and (c) the
planning and modification success needed to achieve full implementation. 

Readers are cautioned that the foregoing discussion regarding Year 2000 computer
issues contains forward-looking statements based on current expectations that
involve risks and uncertainties and should be considered in conjunction with the
following. The failure to correct a material Year 2000 problem could result in
an interruption in, or a failure of, certain normal business activities or
operations of the Company. Such failures could materially and adversely affect
the Company's business, operating results, and financial condition. Due in large
part to the uncertainty of the Year 2000 readiness of third-party suppliers and
customers, as well as the lack of a final Year 2000 project plan for the
remaining internal business systems that are not yet assessed as Year 2000
ready, the Company is currently unable to determine whether the consequences of
Year 2000 issues will have a material impact on the Company's business,
operating results or financial condition. The Company's programs addressing Year
2000 computer issues are expected to reduce the Company's level of uncertainty
regarding Year 2000 issues and, in particular, about the Year 2000 readiness of
its material internal operations, suppliers, customers, and other third-parties.
In addition, the Company believes that the current Year 2000 activities
surrounding the Company's software products and internal systems have reduced
the risk of any disruption caused by any Year 2000 issues in these areas. 

ITEM 2.  PROPERTIES

The Company's headquarters consists of approximately 10,451 square feet located
in a multi-story building in suburban Minneapolis, Minnesota.  The facility is
leased pursuant to an agreement that expires in August 2000. The Company also
maintains offices and leases space for operations and sales functions in
Cupertino and Pleasanton, California, and Boston, Massachusetts of 7,923, 4,905
and 3,942 square feet, respectively.  The Company believes that its facilities
are adequate to meet its anticipated level of operations for the near term.  For
additional information concerning the Company's lease obligations, see Note 3 to
the Company's consolidated financial statements included in this Annual Report
on Form 10-K.

ITEM 3.  LEGAL PROCEEDINGS

From time to time, the Company is involved in litigation relating to claims
arising out of its operations in the normal course of business.  The Company is
not currently involved in any legal proceedings the resolution of which, in
management's opinion, would have a material adverse effect on the Company's
business, financial position or results of operations.

The Company has never paid cash dividends on its capital stock and does not
anticipate declaring or paying any cash dividends in the foreseeable future. 
The Company intends to retain future earnings, if any, for the development of
its business.

As of March 8, 1999, the Company had 3,407 stockholders of record.

In connection with the acquisition of QuickSilver on September 22, 1998, the
Company issued 2,337,980 shares of unregistered Company Common Stock to the
shareholders of QuickSilver, as partial consideration for receipt by the Company
of all of the common stock of QuickSilver.  These shares were subsequently
registered on November 24, 1998.  The Company also issued deferred promissory
notes to the QuickSilver shareholders with an aggregate principal value of $2.16
million.  These notes are convertible into Company Common Stock at the option of
the holder and with the consent of the Company's Board of Directors.  The
conversion ratio for the notes is determined by the average closing price of the
Company's Common Stock on the Nasdaq National Market for the twenty days
preceding the conversion request.  On December 30, 1998, $1.2 million of the
notes were converted to Common Stock, in addition to $19,000 of interest payable
related to such notes.

On October 26, 1998, the Chairman of the Board of the Company, Joseph D.
Costello, purchased 1,000,000 shares of unregistered Series A Preferred Stock
from the Company for the purchase price of $2.00 per share, or a total price of
$2,000,000.  The shares of Preferred Stock converted by their terms into Common
Stock on December 29, 1998, when the Company's shareholders approved increasing
the authorized number of Common Stock shares outstanding.  Proceeds from the
sale of the Preferred Stock will be used to fund general corporate activities.

ITEM 7.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
OF OPERATIONS.

OVERVIEW

Zamba is a national customer care consulting company.  Our services are designed
to assist clients in building lasting relationships with customers, increase the
effectiveness of customer service and sales operations, and improve overall
communication with customers.  We deliver our services using a unique
combination of accumulated expertise in the customer care field, existing
technology, and client knowledge. Typically, we perform our services on a
fixed-bid, fixed-timetable basis.   Rapid development and significant client
involvement are key aspects to our methodologies. We offer our clients
end-to-end assistance with their implementations, including business case
evaluation, system planning and design, software implementation, modification
and development, training, installation, change management, network management,
and on-going support. Our 


                                          10
<PAGE>

services include the design, implementation and integration of several
enterprise level applications to facilitate sales automation, call center
management, marketing automation and automated field service and sales.  

The Company currently derives most of its revenue from systems integration
services including business case evaluation, system planning and design,
software package implementation, custom software development, training,
installation and change management.  The Company also derives recurring revenue
from providing post implementation support.  

The Company's revenues and earnings may fluctuate from quarter to quarter based
on the number, size and scope of projects in which the Company is engaged, the
contractual terms and degree of completion of such projects, any delays incurred
in connection with a project, employee utilization rates, the adequacy of
provisions for losses, the accuracy of estimates of resources required to
complete ongoing projects, and general economic conditions and other factors. In
addition, revenues from a large client may constitute a significant portion of
the Company's total revenues in a particular quarter.

Historically, the Company derived a substantial amount of its revenue from sales
of proprietary hardware and software that originally enabled data communication
over specialized mobile radio ("SMR") technology and, eventually, most types of
wireless networks.  During 1996, the Company began a process to expand the
services it could offer to its clients by becoming a systems integrator focused
on wireless data communication and ceased production of its proprietary
hardware.  During 1997, the Company reduced its workforce from approximately 95
employees to approximately 40 employees; consolidated and closed several
facilities; and reduced the carrying value of certain assets no longer expected
to be used in operations.  As a result of these actions, the Company recorded
one-time charges totaling approximately $1.90 million during the third quarter
of 1997.  The Company took these actions because of slower than expected market
and related revenue growth.  Also, during the second half of 1997 and throughout
1998, the Company broadened its sales focus to providing systems integration
services for customer care including Sales Force Automation, Customer Support,
Marketing, Field Service & Sales Automation, and Call Centers.  

KEY FINANCIAL TRANSACTIONS

On September 22, 1998, the Company completed the acquisition of the QuickSilver
Group, Inc. ("QuickSilver"), a customer care consulting company specializing in
software package implementation for call center management, sales automation,
marketing automation, and automated field service and sales. QuickSilver's
operating results are included in our operating results from September 22, 1998.
For additional information concerning the Company's acquisition of QuickSilver,
see Note 4 to the Company's consolidated financial statements included in this
Annual Report on Form 10-K.

On September 21, 1998, the Company transferred its patented "NextNet" wireless
data technology to an entity of the same name, in conjunction with the receipt
by that entity of $8 million in private investment capital to fund the further
development of the technology.  In concept, the NextNet technology will enable
high-speed data transmission over existing cellular infrastructures at rates not
possible with existing systems. The Company received forty-four percent (44%)
ownership of NextNet, the new company, in exchange for the NextNet technology. 
The Company's investment in NextNet is carried at $0, the historical carrying
basis of the technology transferred, as amounts incurred by the Company up to
the date of the transfer were charged to research and development expense. The
fourth quarter of 1998 was the first quarter in which the Company did not incur
expenses related to the development of the NextNet technology.  Several
long-time employees of the Company also transferred to NextNet.  These employees
were previously engineers who worked on KeyWare and our earlier computing
devices for SMR.


                                          11
<PAGE>

On October 26, 1998, the Company issued 1 million shares of convertible Series A
Junior Participating Preferred Stock to our Chairman, Joe Costello, for the
purchase price of $2 million.  The convertible Preferred Stock automatically
converted to common stock on a 1-to-1 basis upon the approval of the Company's
shareholders on December 29, 1998, to authorize an additional 20 million shares
of Common Stock. 

RESULTS OF OPERATIONS

YEAR ENDED DECEMBER 31, 1998, COMPARED TO YEAR ENDED DECEMBER 31,1997

NET REVENUES

Net revenues increased 44% to $8.12 million in 1998 compared to $5.62 million in
1997, due principally to Company's transition to the sale of its system
integration services instead of selling stand-alone software products and the
acquisition of QuickSilver on September 22, 1998.  As a result of the shift in
focus, services revenues increased to $7.77 million in 1998 from $4.74 million
in 1997 and product revenues decreased to $350,000 in 1998 from $876,000 in
1997.  The Company expects to grow revenues at a similar if not greater rate in
1999.  Product revenues should continue to decline.

COST OF REVENUES

Cost of revenues consists primarily of payroll and payroll related expenses for
personnel dedicated to client assignments and is directly associated with, and
varies with, the level of client services being delivered.  Cost of revenues
were $4.84 million or 60% of revenues in 1998 compared to $5.49 million, or 98%
of net revenues in 1997.  The dollar and percentage decrease resulted from the
cost reduction efforts in the third quarter of 1997, which significantly reduced
the number of employees and related expenses for most of 1998.  Although the
cost of revenue decreased from 1997 compared to 1998 because of the 1997 cost
reduction efforts, due to the acquisition of QuickSilver on September 22, 1998,
project personnel headcount increased 160% to 65 at December 31, 1998, from 25
employees at December 31, 1997.  While the Company expects to meet its hiring
goals in 1999, competition for personnel with information technology skills is
intense and the Company expects salaries and wages to continue to increase.  The
Company periodically reviews and updates its billing rates to cover the expected
increase in costs.  

RESEARCH AND DEVELOPMENT


Research and development expenses were $1.16 million or 14% of net revenues in
1998 compared to $3.29 million or 58% of net revenues in 1997.  The dollar and
percentage decrease is due primarily to the decrease in research and development
personnel which occurred as a result of discontinuing any product development or
enhancements of the KeyWare product line throughout 1998, and the transfer of
the NextNet technology in September of 1998 to an entity of the same name
described in the Key Financial Transactions section in Item 7.  The Company
anticipates no research and development expenses in 1999.   

SALES AND MARKETING

Sales and marketing expenses were $2.21 million or 27% of net revenues in 1998
compared to $4.15 million or 74% of net revenues in 1997. The dollar and
percentage decrease resulted from the cost reduction efforts made by the Company
in the third quarter of 1997 which significantly reduced the number of employees
and related expenses for sales and marketing in 1998. In connection with the
Company's focus on systems integration services, a charge of approximately
$202,000 was recorded in the third quarter of 1997 for severance and facility
consolidation costs in the sales and marketing area.  The Company anticipates
sales and marketing expenses to increase in 1999.    


                                          12
<PAGE>

GENERAL AND ADMINISTRATIVE

General and administrative expenses were $1.90 million or 23% of net revenues in
1998 compared to $2.46 million or 44% of net revenues in 1997.  The dollar and
percentage decrease resulted from the cost reduction efforts made by the Company
in the third quarter of 1997 that significantly reduced the number of employees
and related expenses for 1998.  As the Company grows and expands geographically
in 1999, it anticipates general and administrative expenses to increase. 

AMORTIZATION OF INTANGIBLES

Intangible asset amortization expense in 1998 was $936,000 compared to $0 in
1997.  The increase is due to the acquisition of QuickSilver on September 22,
1998.  The acquisition was accounted for using the purchase method of
accounting.  The purchase price was allocated to tangible and identifiable
intangible assets.  The fair value of the identifiable intangible assets
acquired was $7.70 million and was recorded in the following categories: people
and experiences, client references, client lists, and intellectual property and
delivery methodology.  These amounts are being amortized over the economic
useful lives of between two and four years. 

INTEREST INCOME

Interest income was $225,000 in 1998 compared to $427,000 in 1997.  The decrease
is principally due to decreased cash and investment balances which were used to
fund operating activities.    

INTEREST EXPENSE

Interest expense in 1998 was $46,000 compared to $0 in 1997.  The increase is
due to interest expense related to the notes payable issued in September 1998 in
connection with the acquisition of QuickSilver.

YEAR ENDED DECEMBER 31, 1997, COMPARED TO YEAR ENDED DECEMBER 31, 1996

NET REVENUES

Net revenues decreased 18% to $5.62 million in 1997 compared to $6.88 million in
1996 due principally to discontinuing the production, purchase and distribution
of SMR products. In 1997, the Company completed its exit from the SMR hardware
business and continued its transition to focusing on the sale of its system
integration services instead of selling stand-alone software products. As a
result of these decisions, product revenues decreased to $876,000 in 1997 from 
$1.90 million in 1996.  Additionally, the Company began to shift the focus of
its business from performing small, technical roles within larger projects to
providing its clients with management and implementation assistance for those
projects.  These larger opportunities require longer sales development time than
do technical assistance, and the transition to this mode of sales required a
significant amount of time and attention from the Company's management and key
personnel.  

COST OF REVENUES

Cost of revenues consists primarily of payroll and payroll related expenses. 
Cost of revenues were $5.49 million or 98% of net revenues in 1997 compared to
$5.53 million or 80% of net revenues in 1996.  

Cost of service revenues were $4.23 million and $3.50 million for the years
ended December 31, 1997, and 1996, respectively.  The increases in costs
resulted primarily from the cost of recruiting personnel with the skills to
deliver large systems integration projects, and the transfer and utilization of
certain research and development and sales and marketing personnel into the
systems integration services group.  The one-time charges recorded during the
third quarter of 1997 included approximately $211,000 of severance and related
costs associated with eliminating 


                                          13
<PAGE>

personnel with specializations in areas no longer pertinent to the Company's
systems integration offerings.

Cost of product revenues were $1.27 million and $2.03 million for the years
ended December 31, 1997, and 1996, respectively.  The decrease from 1996 to 1997
is primarily due to a $900,000 charge recorded in the first quarter of 1996,
resulting from the Company's decision to write down its remaining SMR hardware
inventories to their net realizable values at that time.  The Company recorded
one-time charges in the third quarter of 1997, including approximately $425,000
relating to completing the Company's exit from SMR hardware production and
distribution. 

RESEARCH AND DEVELOPMENT

Research and development expenses were $3.29 million or 58% of net revenues in
1997 compared to $4.21 million or 61% of net revenues in 1996.  The dollar and
percentage decrease is due primarily to the focus on systems integration
services rather than product sales, resulting in a reduction of research and
development staff during the third quarter of 1997. 

SALES AND MARKETING

Sales and marketing expenses were $4.15 million or 74% of net revenues in 1997
compared to $6.25 million or 91% of net revenues in 1996.  The dollar and
percentage decrease is primarily related to payroll and payroll related
expenditures associated with the decrease in sales and marketing personnel. In
connection with the Company's focus on systems integration services, a charge of
approximately $202,000 was recorded in the third quarter of 1997 for severance
and facility consolidation costs in the sales and marketing area.

GENERAL AND ADMINISTRATIVE

General and administrative expenses were $2.46 million or 44% of net revenues in
1997 compared to $2.0 million or 29% of net revenues in 1996. The increase in
1997 is primarily due to approximately $803,000 of facility and relocation
charges recorded in the third quarter of 1997. 

INTEREST INCOME

Interest income decreased to $427,000 in 1997 from $859,000 in 1996.  This
decrease is principally due to decreased cash and investment balances which were
used to fund operating activities.    

LIQUIDITY AND CAPITAL RESOURCES 

As of December 31, 1998, the Company had no significant capital spending or
purchase commitments and had cash and cash equivalents totaling $2.96 million
and working capital of $4.12 million.  For the years ended December 31, 1998,
and 1997 the Company used $2.35 million and $6.71 million respectively of cash
for operating activities and $2.1 million, net of cash acquired, for the
acquisition of QuickSilver.  The amount of cash used in operating activities
during 1998 and 1997 decreased as a result of cost-reduction efforts made by the
Company in the third quarter of 1997 which significantly reduced the number of
employees and related expenses for 1998.  The Company enhanced its cash position
on October 26, 1998, when we issued 1.0 million  shares of Series A Junior
Participating Preferred Stock to our Chairman, Joe Costello, for the purchase
price of $2.0 million.  These shares were converted to Common Stock on December
29, 1998.  The Company believes its existing capital resources will be
suffucient to meet its capital requirements into 2000.

NEW ACCOUNTING STANDARDS

Statement of Financial Accounting Standard No. 133 "Accounting for Derivative
Instruments and Hedging Activities" (SFAS No. 133), effective in 2000,
establishes new standards for recognizing all derivatives as either assets or
liabilities, and measuring those instruments at fair value.  At the 


                                          14
<PAGE>

present time, the Company does not anticipate that SFAS No. 133 will have a
material impact on its financial position or results of operations.

FACTORS THAT MAY AFFECT FUTURE RESULTS

There can be no assurance that the Company's business will grow as anticipated
or that the Company will achieve or sustain profitability on a quarterly or
annual basis in the future.  The Company derives a substantial part of its
revenues from a small number of clients whom, after evaluating the Company's
capabilities, decide whether to engage the Company to create business case
evaluations, consult on change management practices and, in some cases, to
design, implement and deploy their customer care systems.  A decision by any one
of these clients to delay a customer care project may have a material adverse
effect on the Company's business and results of operations.

In order for the Company's revenues from consulting and integration services to
grow, the Company must continue to add more clients and larger projects to plan,
design and implement customer care systems.  The Company's inability to obtain
clients for large-scale consulting and integration services could materially and
adversely affect the growth of its business.

In addition to the factors listed above, actual results could vary materially
from the foregoing forward-looking statements due to the Company's inability to
hire and retain qualified personnel, the risk that the Company may need to
enhance products and services beyond what is currently planned, the levels of
promotion and marketing required to promote the Company's products and services
so as to attain a competitive position in the marketplace, or other risks and
uncertainties identified in this Annual Report and the Company's other filings
with the SEC.

ITEM 7A.  QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

The Company is exposed to certain market risks based on the outstanding 
long-term debt obligations of $1.03 million at December 31, 1998.  As 
discussed in Note 5 to the consolidated financial statements, the interest 
rate on the Company's long-term debt obligation is 7%, and the obligation 
matures quarterly on an installment basis commencing in December 1999 and 
ending in December 2003. The Company does not invest in any derivative 
financial instruments.

ITEM 9.  CHANGES IN AND DISAGREEMENTS WITH ACCOUNTANTS ON ACCOUNTING AND
FINANCIAL DISCLOSURE.

On January 25, 1999, PricewaterhouseCoopers LLP ("PwC") resigned as the
Company's independent accountants, because the Company intended to enter into a
business relationship with the technology consulting practice of PwC. 
Subsequently, the Company has entered into a formal business relationship with
PwC.  The reports of PwC on the financial statements of the Company for the
years ended December 31, 1997, and 1996, did not contain an adverse opinion or a
disclaimer of opinion and were not qualified or modified as to uncertainty,
audit scope, or accounting principles. In connection with the audits of the
Company's financial statements for the years ended December 31, 1997, and 1996,
and through January 25, 1999, there were no "reportable events" as that term is
described in Item 304(a)(1)(v) of Regulation S-K, and there were no
disagreements between the Company and PwC on any matters of accounting
principles or practices, financial statement disclosure or auditing scope or
procedure, which disagreements, if not resolved to the satisfaction of PwC would
have caused PwC to make reference to the matter in their reports on the
financial statements for such years.

On February 8, 1999, the Audit Committee of the Board of Directors of the
Company approved the retention of KPMG Peat Marwick LLP ("KPMG") to be the
Company's new independent accountants. During the two fiscal years ended
December 31, 1997, and December 31, 1998, and for the interim period through
February 8, 1999, the Company did not seek advice from KPMG regarding (i) the
application of accounting principles to a specified transaction or the type of
audit opinion that might be rendered on the Company's financial statements; or
(ii) any matter that was either the subject of a disagreement, as defined in
paragraph (a)(1)(iv) of Item 304 of Regulation S-K or a reportable event, as
described in paragraph (a)(1)(v) of Item 304 of Regulation S-K.

The resignation of PwC and retention of KPMG were reported on 8-K filings with
the Securities and Exchange Commission on January 26, 1999, and February 12,
1999, respectively.

ZAMBA CORPORATION
CONSOLIDATED NOTES TO FINANCIAL STATEMENTS

1.   SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:

BUSINESS DESCRIPTION:
Zamba Corporation ("Zamba" or "the Company") is a national dedicated customer
care consulting company.  The Company's services are designed to assist clients
in building lasting relationships with customers, increase the effectiveness of
customer service and sales operations and improve overall communication with
customers.  Prior to October 1998, the Company was known as Racotek, Inc.

BASIS OF REPORTING
The accompanying consolidated financial statements include the accounts of the
Company and its wholly owned subsidiary, which was acquired during 1998 (see
Note 4).  All intercompany accounts and balances have been eliminated in
consolidation.

USE OF ESTIMATES:
The preparation of financial statements in conformity with generally accepted
accounting principles requires management to make estimates and assumptions that
affect the reported amounts of assets and liabilities and disclosure of
contingent assets and liabilities at the date of the financial statements and
the reported amounts of revenues and expenses during the reporting period. 
Actual results could differ from those estimates.

CASH EQUIVALENTS AND INVESTMENTS:
The Company considers all highly liquid investments in money market funds or
other investments with initial maturities of three months or less to be cash
equivalents.  Investments with original maturities in excess of three months are
classified as short-term or long-term investments based on their remaining
maturities.  

The Company had no non-cash equivalent  investments as of December 31, 1998 and
in 1997, investments were considered by management to be "held to maturity," and
therefore were reported at their amortized cost.  Amortization of premiums or
discounts are included in results of operations (see Note 2).  

REVENUE RECOGNITION:
Revenues from fixed bid contracts are recognized as the services are performed
based on the percent-of-completion method (the ratio of hours incurred to total
estimated hours to complete the contract).  Revenue from time and material
contracts are recognized as the services are performed.  Customer support
revenues are recognized ratably over the term of the underlying support
agreements.

Deferred revenue is comprised of amounts received or billed in advance of
services to be performed.  Unbilled revenue represents amounts recognized on
services performed in advance of billings in accordance with the terms of the
contract.

Revenue from software sold under license agreements, included in product
revenue, is recognized as revenue upon shipment if there are no post-delivery
obligations, and if the terms of the agreement are such that the payment of the
obligation is non-cancelable and non-refundable.  Generally, other product
revenue is recognized upon shipment.  

Effective January 1, 1998, the Company adopted Statement of Position (SOP) 97-2,
"Software Revenue Recognition". The adoption  of this SOP has had no effect on
the Company's revenue recognition practices or any impact on  its financial
position or results of operations.

RESEARCH AND DEVELOPMENT COSTS:
The Company capitalizes software development costs incurred in developing a
product once technological feasibility of the product has been determined.  The
establishment of technological feasibility and the ongoing assessment of the
recoverability of these costs requires considerable judgment by management with
respect to certain external factors, including, but not limited to, anticipated
future gross product revenue, estimated economic life and changes in software
and hardware technology.  Amortization of capitalized software development costs
begins when the product is available for general release to customers and is
computed on the basis of each 


                                          27

CONSOLIDATED NOTES TO FINANCIAL STATEMENTS

product's projected revenues, but not less than on a straight-line basis over
the remaining estimated economic life of the product.  

There were no software development costs capitalized during 1998, 1997, and
1996.  Amortization expense of $0, $121,000, and $120,000 relating to
capitalized costs was recognized for the years ended December 31, 1998, 1997,
and 1996, respectively.

All other research and development expenditures are charged to expense as
incurred.  

After the transfer of the NextNet technology in September 1998 (see Note 6) the
Company does not anticipate significant research and development projects and
expenses in 1999.  

PROPERTY AND EQUIPMENT:
Property and equipment are stated at cost.  Significant additions or
improvements extending asset lives are capitalized; normal maintenance and
repair costs are expensed as incurred.  Depreciation is determined using the
straight-line method over the estimated useful lives of the assets which range
from two to seven years.  Leasehold improvements are amortized on a
straight-line basis over the shorter of the estimated useful lives of the assets
or the underlying lease term (approximately five years).  The cost and related
accumulated depreciation or amortization of assets sold or disposed of are
removed from the accounts and the resulting gain or loss is included in
operations.

INTANGIBLE ASSETS:
Intangible assets are being amortized over the economic useful lives of between
two and five years.

The Company assesses the potential impairment of its intangible assets based on
anticipated cash flows from operations.  No impairment charges were recorded in
1998, 1997 or 1996.

INCOME TAXES:
The Company utilizes the asset and liability method of accounting for income
taxes whereby deferred taxes are determined based on the difference between the
financial statement and tax bases of assets and liabilities using enacted tax
rates in effect for the years in which the differences are expected to reverse. 
Valuation allowances are established when necessary to reduce deferred tax
assets to the amount expected to be realized.  Income tax expense is the sum of
the tax currently payable and the change in the deferred tax assets and
liabilities during the period.

STOCK-BASED COMPENSATION:
The Company has chosen to account for stock-based compensation using the
intrinsic value method prescribed in Accounting Principles Board Opinion No. 25,
"Accounting for Stock Issued to Employees," and related interpretations.  The
Company accounts for stock-based compensation to non-employees using the fair
value method prescribed by Statements of Financial Accounting Standards (SFAS)
No. 123.  Accordingly, compensation costs for stock options granted to employees
are measured as the excess, if any, of the value of the Company's stock at the
date of the grant over the amount an employee must pay to acquire the stock. 
Compensation cost for stock options granted to non-employees is measured as the
fair value of the option at the date of grant.  Such compensation costs, if any,
are amortized on a straight-line basis over the underlying option vesting terms.

NET LOSS PER SHARE:
Basic and diluted net loss per share is computed by dividing the net loss by 
the weighted average number of shares of common stock outstanding during the 
period. Assumed conversion shares were excluded from the net loss per share 
computation as their effect is antidilutive.  Common stock options could 
potentially dilute basic earnings per share in future periods if the Company 
generates net income.

1.   SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES, CONTINUED:

BUSINESS SEGMENTS:
Effective at year-end 1998, the Company adopted SFAS No. 131, "Disclosure 
About Segments of an Enterprise and Related Information," which requires 
disclosure of segment data in a manner consistent with that used by an 
enterprise for internal management reporting and decision making.  The 
Company reports its operations as a single segment under SFAS No. 131.

RECLASSIFICATIONS:
Certain prior year amounts have been reclassified to conform to the current year
presentation.

INVESTMENTS 
The Company's investments consisted of $0 and $2.23 million of U.S. Government
and agency debt securities in 1998 and 1997, respectively, including unamortized
discounts of $17,000 in 1997.

3.   LEASE COMMITMENTS:

The Company maintains its corporate office in Minnesota and operating offices 
in California and Massachusetts under terms of noncancelable operating leases 
which expire between August 2000 and May 2003.  These leases require the 
Company to pay a pro rata share of the lessor's operating costs.

The Minnesota lease requires Zamba to maintain a restricted cash balance as 
security for the Company's obligations under the lease.  The remaining leases 
require the Company to provide security deposits as part of the lease 
agreement. Total rent expense, including a pro rata share of the lessor's 
operating costs, were $286,000, $767,000, and $642,000 for the years ended 
December 31, 1998, 1997 and 1996, respectively.

4.   ACQUISITION:

On September 22, 1998, the Company completed the acquisition of the QuickSilver
Group, Inc., ("QuickSilver") a customer care consulting company specializing in

7.   STOCKHOLDERS' EQUITY, CONTINUED:

STOCK-BASED COMPENSATION:
No compensation cost has been recognized for stock options granted to employees
or directors under the 1989 Stock Option Plan, the 1993 Equity Incentive Plan,
1993 Directors Option Plan, 1998 Non-Officers Plan or the 1997 Stock Option Plan
for Key Employees, Consultants and Directors of QuickSilver Group, Inc.
(collectively referred to as "the Plans").  Had compensation cost for the Plans
been determined based on the fair value of options at the grant date for awards
in 1998, 1997 and 1996, the Company's net loss and net loss per share would have
increased to the pro forma amounts indicated below:

</TABLE>

The pro forma effect on the net loss for 1998, 1997 and 1996 is not fully
representative of the pro forma affect on net earnings (loss) in future years
because these years do not take into consideration pro forma compensation
expense related to grants made prior to 1995.  In relation to the option
repricing described previously, the above proforma compensation expense includes
$120,000 and $37,000, for 1998 and 1997, respectively.

The aggregate fair value of options granted during 1998, 1997 and 1996,
respectively, was $3.53 million, $881,000 and $1.67 million for the 1993 Equity
Incentive Plan, $47,000, $193,000, and $328,000 for the 1993 Directors Option
Plan, $687,000, $0, and $0 for the 1998 Non-Officer Option Plan and $351,000,
$0, and $0 for the 1997 Stock Option Plan for Key Employees, Consultants and
Directors of QuickSilver Group, Inc.  The aggregate fair value was calculated by
using the fair value of each option grant on the date of grant, utilizing the
Black-Scholes option-pricing model and the following key assumptions for the
Plans:

PREFERRED STOCK:
The Company's certificate of incorporation authorizes issuance of up to 5.0

Board of Directors of the Company for $2.00 per share.  These shares converted
by their terms to common stock on December 29, 1998.  There were no preferred
shares issued or outstanding as of December 31, 1998 or 1997.

WARRANTS:
In connection with the acquisition of QuickSilver stock warrants to purchase
QuickSilver common stock were converted to 462,247 warrants to purchase Zamba
common stock.  These warrants are immediately exercisable, but the underlying
acquired shares cannot be sold until after March 22, 1999, and expire on March
9, 2008. 

STOCKHOLDER RIGHTS PLAN:
On September 7, 1994, the Board of Directors adopted a Stockholder Rights Plan. 
Under this plan, the Board of Directors declared a dividend of one preferred
share purchase right (a "Right") for each share of common stock outstanding as
of September 28, 1994 (the "Record Date").  In addition, one Right will be
issued with each share of common stock that becomes outstanding after the Record
Date, except in certain circumstances.  All Rights will expire on September 12,
2004, unless the Company extends the expiration date, redeems the Rights or
exchanges the Rights for common stock.

The Rights are initially attached to the Company's Common Stock and will not
trade separately.  If a person or a group acquires 20 percent or more of the
Company's common stock (an "Acquiring Person") or announces an intention to make
a tender offer for 20 percent or more of the Company's common stock, then the
Rights will be distributed (the "Distribution Date") and will thereafter trade
separately from the common stock.  Upon the Distribution Date, each Right may be
exercised for 1/100th of a share of a newly designated Series A Junior
Participating Preferred Stock at an exercise price of $25.00.

Upon a person or group becoming an Acquiring Person, holders of the Rights
(other than the Acquiring Person) will have the right to acquire shares of the
Company's common stock at a substantially discounted price in lieu of the
preferred stock. Additionally, if, after the Distribution Date, the Company
merges into or engages in certain other business combination transactions with
an Acquiring Person or 50 percent or more of its assets are sold in a
transaction with an Acquiring Person, the holders of Rights (other than the
Acquiring Person) will have the right to receive shares of common stock of the
acquiring corporation at a substantially discounted price.

After a person or a group has become an Acquiring Person, the Company's Board of
Directors may, at its option, require the exchange of outstanding Rights (other
than those held by the Acquiring Person) for common stock at an exchange ratio
of one share of the Company's common stock per Right.  The board also has the
right to redeem outstanding Rights at any time prior to the Distribution Date
(or later in certain circumstances) at a price of $0.005 per Right.  The terms
of the Rights, including the period to redeem the Rights, may be amended by the
Company's Board of Directors in certain circumstances.

8.   INCOME TAXES:

The Company has incurred net operating losses since inception.  Because of the
uncertainty about whether the Company will have taxable earnings in the future,
the Company has not reflected any benefit of such net operating loss
carryforwards in the accompanying consolidated financial statements.

At December 31, 1998, the Company has approximately $70.8 million of net
operating loss carryforwards for both financial statement and for federal income
tax purposes that begin to expire in 2005.  The use of these carryforwards in
any one year is limited under Internal Revenue Code Section 382 because of
significant ownership changes.  In addition, the net operating loss carryforward
of QuickSilver is limited under the federal consolidated tax return rules.

by applying the federal corporate tax rate, as follow:

Valulation allowances have been established for the entire tax benefit
associated with the carryforwards and net future deductible temporary
differences as of December 31, 1998, 1997 and 1996.

The tax effect of items that comprise a significant portion of deferred tax
assets is:

                                         -----------         -----------

</TABLE>

Due to the uncertainty surrounding the timing of realizing the benefits of its
favorable tax attributes in future tax returns, the Company has placed a
valuation allowance against its otherwise recognizable deferred tax assets.


9.   EMPLOYEE SAVINGS PLAN:  

The Company offers a 401(k) defined contribution benefit plan for which all 
regular employees are eligible.  Participants may contribute up to 20% of 
their compensation in any plan year subject to an annual limitation.  
Employer contributions may be made at the discretion of the Company's Board 
of Directors. No Company contributions have been made to the Plan.


10.  MAJOR CUSTOMERS:  

A portion of the Company's revenues have been derived from major clients for the
years ended December 31, 1998, 1997 and 1996 as follows:

</TABLE>


11.  FAIR VALUE OF FINANCIAL INSTRUMENTS:

The carrying amount for cash and cash equivalents, short-term investments and
long-term debt approximates fair value because of the short maturity of those
instruments.

             FOURTH AMENDED AND RESTATED CERTIFICATE OF INCORPORATION OF
                                  ZAMBA CORPORATION

     Zamba Corporation, a corporation organized and existing under the laws of
the State of Delaware hereby certifies as follows:

     FIRST:  The name of this corporation (hereinafter the "Corporation") is
ZAMBA CORPORATION.  The name was changed to Zamba Corporation from Racotek, Inc.
on October 5, 1998, in connection with a merger that was completed on September
22, 1998.  The corporation was originally incorporated under the name RaCoTek,
Inc. and the date of filing of its original Certificate of Incorporation with
the Secretary of State of the State of Delaware is August 15, 1990.  The current
articles of incorporation, the Third Amended and Restated Certificate of
Incorporation, are dated December 17, 1993.

     SECOND:  The text of the Third Amended and Restated Certificate of
Incorporation of the Corporation is hereby amended and restated in its entirety
to become the Fourth Amended and Restated Certificate of Incorporation and to
read as follows:

                                      ARTICLE 1

     The name of this Corporation is Zamba Corporation.

                                      ARTICLE 2

     The address of the registered office of the Corporation in the State of
Delaware is The Prentice-Hall Corporation System, Inc., 1013 Centre Road,
Wilmington, Delaware 19805, County of New Castle, and the name of the registered
agent of the Corporation in the State of Delaware at such address is:  The
Prentice-Hall Corporation System, Inc.

                                      ARTICLE 3

     The purposes and powers of the Corporation shall be to conduct any lawful
act or activity, for which corporations may be organized under the General
Corporation Law of the State of Delaware.

                                      ARTICLE 4

     SECTION 1.     CLASSES OF STOCK

     This Corporation is authorized to issue two classes of stock to be
designated, respectively, "Common Stock" and "Preferred Stock", both of which
shall have a par value of $0.01 per share.  The total number of shares which the
Corporation is authorized to issue is 60,000,000, of which 55,000,000 shares
shall be Common Stock and 5,000,000 shares shall be Preferred Stock.

     SECTION 2.     DESIGNATION OF SERIES OF PREFERRED STOCK

     The Board of Directors is authorized to provide for the issuance of the
shares of Preferred Stock in one or more series, and, by filing a certificate of
designation pursuant to the General Corporation Law of the State of Delaware, to
establish from time to time the number of shares to be included in each such
series, to fix the designation, powers, preferences and rights of the shares of
each such series and any qualifications, limitations or restrictions thereof,
and to increase or decrease the number of shares of any such series (but not
above the total number of shares of Preferred Stock authorized when combined
with other series of Preferred Stock nor below the number of shares of such
series then outstanding).  In case the number of shares of any series shall be
so decreased, the shares constituting such decrease shall resume the status that
they had prior the adoption of the resolution originally fixing the number of
shares of such series.

     Except as may be expressly provided in any Certificate of Designation
designating any series of Preferred Stock pursuant to the foregoing provisions
of this Article 4, any new series of Preferred Stock may be designated,


                                          39

<PAGE>

fixed and determined as provided herein by the Board of Directors without
approval of the holders of Common Stock or the holders of Preferred Stock, or
any series thereof, and any such new series may have powers, preferences and
rights, including, without limitation, voting rights, dividend rights,
liquidation rights, redemption rights and conversion rights, senior to, junior
to or pari passu with the rights of the Common Stock, the Preferred Stock, or
any future class or series of Preferred Stock or Common Stock.

                                      ARTICLE 5

     A director of the Corporation shall not be personally liable to the
Corporation or its stockholders for monetary damages for breach of fiduciary
duty as a director, except for (i) liability based on a breach of the duty of
loyalty to the Corporation or its stockholders; (ii) liability for acts or
omissions not in good faith or that involve intentional misconduct or a knowing
violation of law; (iii) liability based on the payment of an improper dividend
or an improper repurchase of the Corporation's stock under Section 174 of the
General Corporation Law of the State of Delaware; or (iv) liability for any
transaction for which the director derived an improper personal benefit.  If the
General Corporation Law of the State of Delaware is hereafter amended to
authorize the further elimination or limitation of the liability of directors,
then the liability of a director of the Corporation in addition to the
limitation on personal liability provided herein, shall be limited to the
fullest extent permitted by the amended General Corporation Law of the State of
Delaware.  Any repeal or modification of this Article by the stockholders of the
Corporation shall be prospective only and shall not adversely affect any
limitation on the personal liability of a director of the Corporation existing
at the time of such repeal or modification.

                                      ARTICLE 6

     The power to adopt, amend, or repeal the Bylaws of this Corporation is
hereby conferred upon the Board of Directors to the full extent permitted by

<PAGE>

          3.1  ORGANIZATION, GOOD STANDING AND QUALIFICATION. The Company is a
corporation duly organized, validly existing and in good standing under the laws
of the State of Delaware.  The Company has all requisite corporate power and
authority to own and operate its properties and assets, to execute and deliver
this Agreement, to issue and sell the Shares (and, upon the approval by the
Company's shareholders of additional authorized shares of Common Stock, the
Conversion Shares) and to carry out the provisions of this Agreement and to
carry on its business as presently conducted and as presently proposed to be
conducted.  The Company is duly qualified and is authorized to do business and
is in good standing as a foreign corporation in all jurisdictions in which the
nature of its activities and of its properties (both owned and leased) makes
such qualification necessary, except for those jurisdictions in which failure to
do so would not have a material adverse effect on the Company or its business.  

          3.2  CAPITALIZATION; VOTING RIGHTS.  The rights, preferences,
privileges and restrictions of the Shares are as stated in the Certificate of
Designation.  The Conversion Shares have been duly and validly reserved for
issuance.  When issued in compliance with the provisions of this Agreement and
the Certificate of Designation, the Shares and the Conversion Shares will be
validly issued, fully paid and nonassessable, and will be free of any liens or
encumbrances; provided, however, that the Shares and the Conversion Shares may
be subject to restrictions on transfer under state and/or federal securities
laws as set forth herein or as otherwise required by such laws at the time a
transfer is proposed.

          3.3  AUTHORIZATION; BINDING OBLIGATIONS. All corporate action on the
part of the Company, its officers, directors and shareholders necessary for the
authorization of this Agreement, the Certificate of Designation and the Investor
Rights Agreement of even date herewith between the Company and the Purchaser
(the "Related Agreements") and the Related Agreements, the performance of all
obligations of the Company hereunder and thereunder at the Closing and the
authorization, sale, issuance and delivery of the Shares pursuant hereto (and,
upon the approval by the Company's shareholders of additional authorized shares
of Common Stock, the Conversion Shares) has been taken or will be taken prior to
the Closing.  This Agreement, when executed and delivered, will be a valid and
binding obligation of the Company enforceable in accordance with its terms,
except as limited by (a) applicable bankruptcy, insolvency, reorganization,
moratorium or other laws of general application affecting enforcement of
creditors' rights; and (b) general principles of equity that restrict the
availability of equitable remedies.  The sale of the Shares and the subsequent
conversion of the Shares into Conversion Shares are not and will not be subject
to any preemptive rights or rights of first refusal that have not been properly
waived or complied with.

          3.4  FINANCIAL STATEMENTS. The Company has made available to the
Purchaser (a) its unaudited balance sheet as at December 31, 1997 and unaudited
statement of income and cash flows for the twelve months ending December 31,
1997 and (b) its unaudited balance sheet as at September 30, 1998 (the
"Statement Date") and unaudited consolidated statement of income and cash flows
for the nine month period ending on the Statement Date (collectively, the
"Financial Statements").  The Financial Statements, together with the notes
thereto, have been prepared in accordance with generally accepted accounting
principles applied on a consistent basis throughout the periods indicated,
except as disclosed therein, and present fairly the financial condition and
position of the Company as of December 31, 1997 and the Statement Date;
provided, however, that the unaudited financial statements are subject to normal
recurring year-end audit adjustments (which are not expected to be material),
and do not contain all footnotes required under generally accepted accounting
principles.

          3.5  LIABILITIES. The Company has no material liabilities and, to the
best of its knowledge, knows of no material contingent liabilities not disclosed
in the Financial Statements, except current liabilities incurred in the ordinary
course of business subsequent to the Statement Date which have not been, either
in any individual case or in the aggregate, materially adverse.


          3.6  CHANGES. Since the Statement Date, there has not been to the
Company's knowledge any event or condition of any character that, either
individually or cumulatively, has materially and adversely affected the
business, assets, liabilities, financial condition, operations or prospects of
the Company.

          3.7  TITLE TO PROPERTIES AND ASSETS; LIENS, ETC. The Company has good
and marketable title to its properties and assets, including the properties and
assets reflected in the most recent balance sheet included in the Financial
Statements, and good title to its leasehold estates, in each case subject to no
mortgage, pledge, lien, lease, encumbrance or charge, other than (a) those
resulting from taxes which have not yet become delinquent, (b) minor liens and
encumbrances which do not materially detract from the value of the property
subject thereto or


                                          42

<PAGE>

materially impair the operations of the Company, and (c) those that have
otherwise arisen in the ordinary course of business.  All facilities, machinery,
equipment, fixtures, vehicles and other properties owned, leased or used by the
Company are in good operating condition and repair and are reasonably fit and
usable for the purposes for which they are being used.  The Company is in
compliance with all material terms of each lease to which it is a party or is
otherwise bound.

          3.8  PATENTS AND TRADEMARKS. To the best of its knowledge, the Company
owns or possesses sufficient legal rights to all patents, trademarks, service
marks, trade names, copyrights, trade secrets, licenses, information and other
proprietary rights and processes necessary for its business as now conducted and
as presently proposed to be conducted, without any known infringement of the
rights of others.  There are no outstanding options, licenses or agreements of
any kind relating to the foregoing, nor is the Company bound by or a party to
any options, licenses or agreements of any kind with respect to the patents,
trademarks, service marks, trade names, copyrights, trade secrets, licenses,
information and other proprietary rights and processes of any other person or
entity other than such licenses or agreements arising from the purchase of "off
the shelf" or standard products.  The Company has not received any
communications alleging that the Company has violated or, by conducting its
business as presently proposed in the SEC Documents (as hereafter defined),
would violate any of the patents, trademarks, service marks, trade names,
copyrights or trade secrets or other proprietary rights of any other person or
entity.  The Company is not aware that any of its employees is obligated under
any contract (including licenses, covenants or commitments of any nature) or
other agreement, or subject to any judgment, decree or order of any court or
administrative agency, that would interfere with their duties to the Company or
that would conflict with the Company's business as presently proposed to be
conducted in the SEC Documents (as hereafter defined).  The Company does not
believe it is or will be necessary to utilize any inventions, trade secrets or
proprietary information of any of its employees made prior to their employment
by the Company, except for inventions, trade secrets or proprietary information
that have been assigned to the Company.

          3.9  COMPLIANCE WITH OTHER INSTRUMENTS. The Company is not in
violation or default of any term of its Certificate of Incorporation or Bylaws,
or of any provision of any mortgage, indenture, contract, agreement, instrument
or contract to which it is party or by which it is bound or of any judgment,
decree, order, writ or, to its knowledge, any statute, rule or regulation
applicable to the Company which would materially and adversely affect the
business, assets, liabilities, financial condition, operations or prospects of
the Company.  The execution, delivery, and performance of and compliance with
this Agreement, and the Related Agreements, and the issuance and sale of the
Shares pursuant hereto and of the Conversion Shares pursuant to the Restated
Charter, will not, with or without the passage of time or giving of notice,
result in any such material violation, or be in conflict with or constitute a
default under any such term, or result in the creation of any mortgage, pledge,
lien, encumbrance or charge upon any of the properties or assets of the Company
or the suspension, revocation, impairment, forfeiture or nonrenewal of any
permit license, authorization or approval applicable to the Company, its
business or operations or any of its assets or properties.

          3.10 LITIGATION. There is no action, suit, proceeding or investigation
pending or to the Company's knowledge currently threatened against the Company
that questions the validity of this Agreement, or the Related Agreements or the
right of the Company to enter into any of such agreements, or to consummate the
transactions contemplated hereby or thereby, or which might result, either
individually or in the aggregate, in any material adverse change in the assets,
condition, affairs or prospects of the Company, financially or otherwise, or any
change in the current equity ownership of the Company, nor is the Company aware
that there is any basis for the foregoing.  The Company is not a party or
subject to the provisions of any order, writ, injunction, judgment or decree of
any court or government agency or instrumentality.

          3.11 TAX RETURNS AND PAYMENTS. The Company has filed all tax 
returns (federal, state and local) required to be filed by it.  All taxes 
shown to be due and payable on such returns, any assessments imposed, and to 
the Company's knowledge all other taxes due and payable by the Company on or 
before the Closing have been paid or will be paid prior to the time they 
become delinquent. The Company has no knowledge of any liability of any tax 
to be imposed upon its properties or assets as of the date of this Agreement 
that is not adequately provided for.

          3.12 COMPLIANCE WITH LAWS; PERMITS. To its knowledge, the Company is
not in violation of any applicable statute, rule, regulation, order or
restriction of any domestic or foreign government or any instrumentality or
agency thereof in respect of the conduct of its business or the ownership of its
properties which violation would materially and adversely affect the business,
assets, liabilities, financial condition, operations or prospects of the
Company.  No governmental orders, permissions, consents, approvals or
authorizations are required to be obtained


                                          43

<PAGE>

and no registrations or declarations are required to be filed in connection with
the execution and delivery of this Agreement and the issuance of the Shares or
the Conversion Shares, except such as has been duly and validly obtained or
filed, or with respect to any filings that must be made after the Closing, as
will be filed in a timely manner.  The Company has all franchises, permits,
licenses and any similar authority necessary for the conduct of its business as
now being conducted by it, the lack of which could materially and adversely
affect the business, properties, prospects or financial condition of the Company
and believes it can obtain, without undue burden or expense, any similar
authority for the conduct of its business as planned to be conducted.

          3.13 OFFERING VALID. Assuming the accuracy of the representations and
warranties of Purchaser contained in Section 4.2 hereof, the offer, sale and
issuance of the Shares and the Conversion Shares will be exempt from the
registration requirements of the Securities Act of 1933, as amended (the
"Securities Act") and will have been registered or qualified (or are exempt from
registration and qualification) under the registration, permit or qualification
requirements of all applicable state securities laws.  Neither the Company nor
any agent on its behalf has solicited or will solicit any offers to sell or has
offered to sell or will offer to sell all or any part of the Shares to any
person or persons so as to bring the sale of such Shares by the Company within
the registration provisions of the Securities Act or any state securities laws.

          3.14 FULL DISCLOSURE. The Company has filed all required reports,
schedules, forms and other documents with the Securities and Exchange Commission
(the "SEC") between January 1, 1997 and the date of this Agreement (the "SEC
Documents").  As of the time each of the SEC Documents was filed with the SEC
(or, if amended or superseded by a filing prior to the date of this Agreement,
then on the date of such filing), (i) the SEC Documents complied in all material
respects with the requirements of applicable law and regulations, and (ii)
except to the extent that information contained in any SEC Document has been
revised or superseded by a later-filed SEC Document, none of the SEC Documents
contained any untrue statement of a material fact or omitted to state a material
fact required to be stated therein or necessary in order to make the statements
therein, in light of the circumstances under which they were made, not
misleading.

          Purchaser hereby represents and warrants to the Company as follows:

          4.1  REQUISITE POWER AND AUTHORITY. Purchaser has all necessary power
and authority under all applicable provisions of law to execute and deliver this
Agreement and the Related Agreements and to carry out their provisions.  All
action on Purchaser's part required for the lawful execution and delivery of
this Agreement and the Related Agreements have been or will be effectively taken
prior to the Closing.  Upon their execution and delivery, this Agreement and the
Related Agreements will be valid and binding obligations of Purchaser,

bankruptcy, insolvency, reorganization, moratorium or other laws of general
application affecting enforcement of creditors' rights, and (b) general
principles of equity that restrict the availability of equitable remedies.

          4.2  INVESTMENT REPRESENTATIONS. Purchaser understands that neither
the Shares nor the Conversion Shares have been registered under the Securities
Act.  Purchaser also understands that the Shares are being offered and sold
pursuant to an exemption from registration contained in the Securities Act based
in part upon Purchaser's representations contained in the Agreement.  Purchaser
hereby represents and warrants as follows:

               (a)  PURCHASER BEARS ECONOMIC RISK.  Purchaser has substantial 
experience in evaluating and investing in private placement transactions of 
securities in companies similar to the Company so that it is capable of 
evaluating the merits and risks of its investment in the Company and has the 
capacity to protect its own interests.  Purchaser must bear the economic risk 
of this investment indefinitely unless the Shares (or the Conversion Shares) 
are registered pursuant to the Securities Act, or an exemption from 
registration is available.  Purchaser understands that the Company has no 
present intention of registering the Shares, the Conversion Shares or any 
shares of its Common Stock. Purchaser also understands that there is no 
assurance that any exemption from registration under the Securities Act will 
be available and that, even if available, such exemption may not allow 
Purchaser to transfer all or any portion of the Shares or the Conversion 
Shares under the circumstances, in the amounts or at the times Purchaser 
might propose.

               (b)  ACQUISITION FOR OWN ACCOUNT.  Purchaser is acquiring the
Shares and the Conversion Shares for Purchaser's own account for investment
only, and not with a view towards their distribution.

               (c)  PURCHASER CAN PROTECT HIS INTEREST.  Purchaser represents
that by reason of its, or of its management's, business or financial experience,
Purchaser has the capacity to protect its own interests in connection with the
transactions contemplated in this Agreement, and the Related Agreements. 
Further, Purchaser is aware of no publication of any advertisement in connection
with the transactions contemplated in the Agreement.

               (d)  ACCREDITED INVESTOR.  Purchaser represents that he is an
accredited investor within the meaning of Regulation D under the Securities Act.

               (e)  COMPANY INFORMATION.  Purchaser has received and read the
Financial Statements and SEC Documents and has had an opportunity to discuss the
Company's business, management and financial affairs with directors, officers
and management of the Company and has had the opportunity to review the
Company's operations and facilities.  Purchaser has also had the opportunity to
ask questions of and receive answers from, the Company and its management
regarding the terms and conditions of this investment.

               (f)  RULE 144.  Purchaser acknowledges and agrees that the
Shares, and, if issued, the Conversion Shares must be held indefinitely unless
they are subsequently registered under the Securities Act or an exemption from
such registration is available.  Purchaser has been advised or is aware of the
provisions of Rule 144 promulgated under the Securities Act as in effect from
time to time, which permits limited resale of shares purchased in a private
placement subject to the satisfaction of certain conditions, including, among
other things:  the availability of certain current public information about the
Company, the resale occurring following the required holding period under Rule
144 and the number of shares being sold during any three-month period not
exceeding specified limitations.

          4.3  TRANSFER RESTRICTIONS. Purchaser acknowledges and agrees that the
Shares and, if issued,  the Conversion Shares are subject to restrictions on
transfer as set forth in the Investor Rights Agreement.

of the terms, covenants and conditions set forth in this Lease. Unless

reasonable and the rental and Lessee's Share (as defined in Paragraph 1.6(b)) 
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, electrical systems, fire sprinkler system, lighting, air 
conditioning and heating systems 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 that any improvements (other than those constructed by Lessee

knowledge of any claim having been made by any governmental agency that a

ordinances exist with regard to the Premises as of the Commencement Date. 
Said warranties shall not apply to any Alterations or Utility Installations 
(defined in Paragraph 7.3(a)) made or to be made by Lessee. If the Premises 
do not comply with said warranties, Lessor shall, except as otherwise 
provided in this Lease, promptly after receipt of written notice from Lessee 
given within six (6) months following the Commencement Date and setting forth 
with specificity the nature and extent of such non-compliance, take such 
action, at Lessor's expense, as may be reasonable or appropriate to rectify 
the non-compliance. Lessor makes no warranty that the Permitted Use in 
Paragraph 1.8 is permitted for the Premises under Applicable Laws (as defined 
in Paragraph 2.4).

restrictions of record (collectively, "APPLICABLE LAWS") 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, is satisfied with reference thereto, and assumes all responsibility 
therefore as the same relate to Lessee's occupancy of the Premises and/or the 
terms 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 
said matters other than as set forth in this Lease. 

       2.5     LESSEE AS 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

correct any non-compliance of the Premises with said warranties.

Unreserved Parking Spaces and Reserved Parking Spaces specified in Paragraph 
1.2(b) on those portions of the Common Areas designated from time to time by 
Lessor for parking.  Lessee shall not use more parking spaces than said number. 
Said parking spaces shall be used for parking by vehicles no larger than

shippers, customers, contractors or invitees to be loaded, unloaded, or parked
in areas other than those designated by Lessor for such activities. 

               (b)     If Lessee permits or allows any of the prohibited 
activities described in this Paragraph 2.6, then Lessor shall have the right, 
without notice, in addition to such other rights and remedies that it may 
have, to remove or tow away the vehicle involved and charge the cost to 
Lessee, which cost shall be immediately payable upon demand by Lessor. 

               (c)     Lessor shall at the Commencement Date of this Lease, 
provide the parking facilities required by Applicable Law.

       2.7     COMMON AREAS--DEFINITION. The term "COMMON AREAS" is defined 
as all areas and facilities outside the Premises and within the exterior 
boundary line of the Industrial Center and interior utility raceways within 
the Premises that are provided and designated by the Lessor from time to time 
for the general non-exclusive use of Lessor, Lessee and other lessees of the 
Industrial Center and their respective employees, suppliers, shippers, 
customers, contractors and invitees, including parking areas, loading and 
unloading areas, trash areas, roadways, sidewalks, walkways, parkways, 
driveways and landscaped areas. 

       2.8     COMMON AREAS--LESSEE'S RIGHTS. Lessor hereby grants to 
Lessee, for the benefit of Lessee and its employees, suppliers, shippers, 
contractors, customers and invitees, during the term of this Lease, the 
non-exclusive right to use, in common with others entitled to such use, the 
Common Areas as they exist from time to time, subject to any rights, powers, 
and privileges reserved by Lessor under the terms hereof or under the terms 
of any rules and regulations or restrictions governing the use of the 
Industrial Center. Under no circumstances shall the right herein granted to 
use the Common Areas be deemed to include the right to store any property, 
temporarily or permanently, in the Common Areas. Any such storage shall be 
permitted only by the prior written consent of Lessor or Lessor's designated 
agent, which consent may be revoked at any time. In the event that any 
unauthorized storage shall occur then Lessor shall have the right, without 
notice, in addition to such other rights and remedies that it may have, to 
remove the property and charge the cost to Lessee, which cost shall be 
immediately payable upon demand by Lessor. 

       2.9     COMMON AREAS--RULES AND REGULATIONS. Lessor or such other 
person(s) as Lessor may appoint shall have the exclusive control and 
management of the Common Areas and shall have the right, from time to time,

respect thereto in accordance with Paragraph 40. Lessee agrees to abide by 
and conform to all such Rules and Regulations, and to cause its employees, 
suppliers, shippers, customers, contractors and invitees to so abide and 
conform. Lessor shall not be responsible to Lessee for the non-compliance 
with said rules and regulations by other lessees of the Industrial Center.

Lessor's sole discretion, from time to time: 

               (a)     To make changes to the Common Areas, including, 
without limitation, changes in the location, size, shape and number of 
driveways, entrances, parking spaces, parking areas, loading and unloading 
areas, ingress, egress, direction of traffic, landscaped areas, walkways and 
utility raceways; 

               (b)     To close temporarily any of the Common Areas for 
maintenance purposes so long as reasonable access to the Premises remains 
available;

               (c)     To designate other land outside the boundaries of the 
Industrial Center to be a part of the Common Areas;

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 an Early Possession Date is specified in 
Paragraph 1.4 and if Lessee totally or partially occupies the Premises after 
the Early Possession Date but prior to the Commencement Date, the obligation 
to pay Base Rent shall be abated for the period of such early occupancy. All 
other terms of this Lease, however, (including but not limited to the 
obligations to pay Lessee's Share of Common Area Operating Expenses and to 
carry the insurance required by Paragraph 8) 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 by the Early Possession Date, if one is 
specified in Paragraph 1.4, or if no Early Possession Date is specified, by 
the Commencement Date, Lessor shall not be subject to any liability therefor, 
nor shall such failure affect the validity of this Lease, or the obligations 
of Lessee hereunder, or extend the term hereof, but in such case, Lessee 
shall not, except as otherwise provided herein, be obligated to pay rent or 
perform any other obligation of Lessee under the terms of this Lease until 
Lessor delivers possession of the Premises to Lessee. If possession of the 
Premises is not delivered to Lessee within sixty (60) days after the 
Commencement Date, Lessee may, at its option, by notice in writing to Lessor 
within ten (10) days after the end of said sixty (60) day period, cancel this 
Lease, in which event the parties shall be discharged from all obligations 
hereunder; provided further, however, that if such written notice of Lessee 
is not received by Lessor within said ten (10) day period, Lessee's right to 
cancel this Lease hereunder shall terminate and be of no further force or 
effect. Except as may be otherwise provided, and regardless of when the 
Original Term actually commences, if possession is not tendered to Lessee 
when required by this Lease and Lessee does not terminate this Lease, as 
aforesaid, the period free of the obligation to pay Base Rent, if any, that 
Lessee would otherwise have enjoyed shall run from the date of delivery of 
possession and continue for a period equal to the period during which the 
Lessee would have otherwise enjoyed under the terms hereof, but minus any 
days of delay caused by the acts, changes or omissions of Lessee. 

4.     RENT.

       4.1     BASE RENT. Lessee shall pay Base Rent and other rent or 
charges, as the same may be adjusted from time to time, to 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 full month shall be prorated based upon the actual number of days of the 
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. 

       4.2     COMMON AREA OPERATING EXPENSES. Lessee shall pay to Lessor 
during the term hereof, in addition to the Base Rent, Lessee's Share (as 
specified in Paragraph 1.6(b)) of all Common Area Operating Expenses, as 
hereinafter defined, during each calendar year of the term of this Lease, in 
accordance with the following provisions:

               (a)     "COMMON AREA OPERATING EXPENSES" are defined, for 
purposes of this Lease, as all costs incurred by Lessor relating to the 
ownership and operation of the Industrial Center, including, but not limited 
to, the following:

                       (i)     The operation, repair and maintenance, in 
neat, clean, good order and condition, of the following:

areas, loading and unloading areas, trash areas, roadways, sidewalks, 
walkways, parkways, driveways, landscaped areas, striping, bumpers, 
irrigation systems, Common Area lighting facilities, fences and gates, 
elevators and roof. 

                               (bb)    Exterior signs and any tenant 
directories. 

                               (cc)    Fire detection and sprinkler systems. 

                       (ii)    The cost of water, gas, electricity and 
telephone to service the Common Areas.

                       (iii)   Trash disposal, property management and 
security services and the costs of any environmental inspections. 

                       (iv)    Reserves set aside for maintenance and repair 
of Common Areas.

                       (v)     Any increase above the Base Real Property Taxes
(as defined in Paragraph 10.2(b)) for the Building and the Common Areas.

                       (vi)    Any "Insurance Cost Increase" (as defined in 
Paragraph 8.1). 

                       (vii)   The cost of insurance carried by Lessor with 
respect to the Common Areas. 

                       (viii)  Any deductible portion of an insured loss 
concerning the Building or the Common Areas. 

                       (ix)    Any other services to be provided by Lessor 
that are stated elsewhere in this Lease to be a Common Area Operating Expense.

               (b)     Any Common Area Operating Expenses and Real Property 
Taxes that are specifically attributable to the Building or to any other 
building in the Industrial Center or to the operation, repair and maintenance 
thereof, shall be allocated entirely to the Building or to such other 
building. However, any Common Area Operating Expenses and Real Property Taxes 
that are not specifically attributable to the Building or to any other 
building or to the operation, repair and maintenance thereof, shall be 
equitably allocated by Lessor to all buildings in the Industrial Center. 

               (c)     The inclusion of the improvements, facilities and 
services set forth in Subparagraph 4.2(a) shall not be deemed to impose an 
obligation upon Lessor to either have said improvements or facilities or to 
provide those services unless the Industrial Center already has the same, 
Lessor already provides the services, or Lessor has agreed elsewhere in this 
Lease to provide the same or some of them. 

               (d)     Lessee's Share of Common Area Operating Expenses shall 
be payable by Lessee within ten (10) days after a reasonably detailed 
statement of actual expenses is presented to Lessee by Lessor. At Lessor's 
option, however, an amount may be estimated by Lessor from time to time of 
Lessee's Share of annual Common Area Operating Expenses and the same shall be 
payable monthly or quarterly, as Lessor shall designate, during each 12-month 
period of the Lease term, on the same day as the Base Rent is due hereunder. 
Lessor shall deliver to Lessee within sixty (60) days after the expiration of 
each calendar year a reasonably detailed statement showing Lessee's Share of 
the actual Common Area Operating Expenses incurred during the preceding year. 
If Lessee's payments under this Paragraph 4.2(d) during said preceding year 
exceed Lessee's Share as indicated on said statement, Lessor shall be 
credited the amount of such overpayment against Lessee's Share of Common 
Area Operating Expenses next becoming due. If Lessee's payments under this 
Paragraph 4.2(d) during said preceding year were less than Lessee's Share as 
indicated on said statement, Lessee shall pay to Lessor the amount of the 
deficiency within ten (10) days after delivery by Lessor to Lessee of said 
statement.

5.     SECURITY DEPOSIT. Lessee shall deposit with Lessor upon Lessee's 
execution hereof the Security Deposit set forth in Paragraph 1.7 as security 
for Lessee's faithful performance of Lessee's obligations under this Lease. 
If Lessee fails to pay Base Rent or other rent or charges due hereunder, or 
otherwise Defaults under this Lease (as defined in Paragraph 13.1), Lessor 
may use, apply or retain all or any portion of said Security Deposit for the 
payment of any amount due Lessor or to reimburse or compensate Lessor for any 
liability, cost, expense, loss or damage (including attorneys' fees) which 
Lessor may suffer or incur by reason thereof. If Lessor uses or applies all 
or any portion of said Security Deposit, Lessee shall within ten (10) days 
after written request therefore deposit monies with Lessor sufficient to 
restore said Security Deposit to the full amount required by this Lease. Any 
time the Base Rent increases during the term of this Lease, Lessee shall, 
upon written request from Lessor, deposit additional monies with Lessor as an 
addition to the Security Deposit so that the total amount of the Security 
Deposit shall at all times bear the same proportion to the then current Base 
Rent as the initial Security Deposit bears to the initial Base Rent set forth 
in Paragraph 1.5. Lessor shall not be required to keep all or any part of the 
Security Deposit separate from its general accounts. Lessor shall, at the 
expiration or earlier termination of the term hereof and after Lessee has 
vacated the Premises, return to Lessee (or, at Lessor's option, to the last 
assignee, if any, of Lessee's interest herein), that portion of the Security 
Deposit not used or applied by Lessor. Unless otherwise expressly agreed in 
writing by Lessor, no part of the Security Deposit shall be considered to be 
held in trust, to bear interest or other increment for its use, or to be 
prepayment for any monies to be paid by Lessee under this Lease.

6.     USE.

       6.1     PERMITTED USE.

               (a)     Lessee shall use and occupy the Premises only for the 
Permitted Use set forth in Paragraph 1.8, or any other legal use which is 
reasonably comparable thereto, and for no other purpose. Lessee shall not use 
or permit the use of the Premises in a manner that is unlawful, creates waste 
or a nuisance, or that disturbs owners and/or occupants of, or causes damage 
to the Premises or neighboring premises or properties.

               (b)     Lessor hereby agrees to not unreasonably withhold or 
delay its consent to any written request by Lessee, Lessee's assignees or 
subtenants, and by prospective assignees and subtenants of Lessee, its 
assignees and subtenants, for a modification of said Permitted Use, so long 
as the same will not impair the structural integrity of the improvements on 
the Premises or in the Building or the mechanical or electrical systems 
therein, does not conflict with uses by other lessees, is not significantly 
more burdensome to the Premises or the Building 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 after 
such request 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 potential 
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 or by-products thereof. Lessee shall not engage in any activity in 
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 Requirements (as defined in Paragraph 6.3). "REPORTABLE 
USE" shall mean (i) the installation or use of any above or below ground 
storage tank, (ii) the generation, possession, storage, use, transportation, 
or disposal of a Hazardous Substance that requires a permit from, or with 
respect to which a report, notice, registration or business plan is required 
to be filed with, any governmental authority, and (iii) the presence in, on 
or about the Premises of a Hazardous Substance with respect to which any 
Applicable Laws require 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 upon notice to 
Lessor and in compliance with all Applicable Requirements, use any ordinary 
and customary materials reasonably required to be used by Lessee in the 
normal course of the Permitted Use, 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 any Reportable Use of any Hazardous Substance 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 therefor, including but not limited to the installation (and, at 
Lessor's option, 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 has come to be located in, on, 
under or about the Premises or the Building, other than as previously 
consented to by Lessor, Lessee shall immediately give Lessor written notice 
thereof, together with 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 
concerning the presence, spill, release, discharge of, or exposure to, such 
Hazardous Substance including but not limited to all such documents as may be 
involved in any Reportable Use involving the Premises. Lessee shall not cause 
or permit any Hazardous Substance to be spilled or released in, on, under or 
about the Premises (including, without limitation, through the plumbing or 
sanitary sewer system).

               (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 damages, liabilities, 
judgments, costs, claims, liens, expenses, penalties, loss of permits and 
attorneys' and consultants' fees arising out of or involving any Hazardous 
Substance brought onto the Premises by or for Lessee or by anyone under 
Lessee's control. Lessee's obligations under this Paragraph 6.2(c) 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 consultants' and attorneys' 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, unless 
specifically so agreed by Lessor in writing at the time of such agreement.

       6.3     LESSEE'S COMPLIANCE WITH REQUIREMENTS. Lessee shall, at 
Lessee's sole cost and expense, fully, diligently and in a timely manner, 
comply with all "APPLICABLE REQUIREMENTS," which term is used in this Lease 
to mean all laws, rules, regulations, ordinances, directives, covenants, 
easements and restrictions of record, permits, the requirements of any 
applicable fire insurance underwriter or rating bureau, and the 
recommendations of Lessor's engineers and/or consultants, relating in any 
manner to the Premises (including but not limited to matters pertaining to 
(i) industrial hygiene, (ii) environmental conditions on, in, under or about 
the Premises, including soil and groundwater conditions, and (iii) the use, 
generation, manufacture, production, installation, maintenance, removal, 
transportation, storage, spill, or release of any Hazardous Substance), now 
in effect or which may hereafter come into effect. 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 Requirements specified by Lessor, and 
shall immediately upon receipt, notify Lessor in writing (with copies of any 
documents involved) of any threatened or actual claim, notice, citation, 
warning, complaint or report pertaining to or involving failure by Lessee or 
the Premises to comply with any Applicable Requirements.

       6.4     INSPECTION; COMPLIANCE WITH LAW. Lessor, Lessor's agents, 
employees, contractors and designated representatives, and the holders of any 
mortgages, deeds of trust or ground leases on the Premises ("LENDERS") 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 Requirements (as defined in Paragraph 6.3), and 
Lessor shall be entitled to employ experts and/or consultants in connection 
therewith to advise Lessor with respect to Lessee's activities, including but 
not limited to Lessee's installation, operation, use, monitoring, 
maintenance, or removal of any Hazardous Substance 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 by Lessee or a 
violation of Applicable Requirements or a contamination, caused or materially 
contributed to by Lessee, is found to exist or to 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 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.

       7.2     LESSOR'S OBLIGATIONS. Subject to the provisions of Paragraphs 
2.2 (Condition), 2.3 (Compliance with Covenants, Restrictions and Building 
Code), 4.2 (Common Area Operating Expenses), 6 (Use), 7.1 (Lessee's 
Obligations), 9 (Damage or Destruction) and 14 (Condemnation), Lessor, 
subject to reimbursement pursuant to Paragraph 4.2, shall keep in good order, 
condition and repair the foundations, exterior walls, structural condition of 
interior bearing walls, exterior roof, fire sprinkler and/or standpipe and 
hose (if located in the Common Areas) or other automatic fire extinguishing 
system including fire alarm

and/or smoke detection systems and equipment, fire hydrants, parking lots, 
walkways, parkways, driveways, landscaping, fences, signs and utility systems 
serving the Common Areas and all parts thereof, as well as providing the 
services for which there is a Common Area Operating Expense pursuant to 
Paragraph 4.2. Lessor shall not be obligated to paint the exterior or 
interior surfaces of exterior walls nor shall Lessor be obligated to 
maintain, repair or replace windows, doors or plate glass of the Premises. 
Lessee expressly waives the benefit of any statute now or hereafter in effect 
which would otherwise afford Lessee the right to make repairs at Lessor's 
expense or to terminate this Lease because of Lessor's failure to keep the 
Building, Industrial Center or Common Areas in good order, condition and 
repair.

       7.3     UTILITY INSTALLATIONS, TRADE FIXTURES, ALTERATIONS.

               (a)     DEFINITIONS; CONSENT REQUIRED. The term "UTILITY 
INSTALLATIONS" is used in this Lease to refer to all 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 which can be 
removed without doing material damage to the Premises. The term "ALTERATIONS" 
shall mean any modification of the improvements on the Premises which are 
provided by Lessor under the terms of this Lease, other than Utility 
Installations or Trade Fixtures. "LESSEE-OWNED ALTERATIONS AND/OR UTILITY 
INSTALLATIONS" are defined as Alterations and/or Utility Installations made 
by Lessee that are not yet owned by Lessor pursuant to Paragraph 7.4(a). 
Lessee shall not make nor cause to be made 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) without 
Lessor's consent but upon notice to Lessor, so long as they are not visible 
from the outside of the Premises, do not involve puncturing, relocating or 
removing the roof or any existing walls, or changing or interfering with the 
fire sprinkler or fire detection systems and the cumulative cost thereof 
during the term of this Lease as extended does not exceed $2,500.00.

               (b)     CONSENT. Any Alterations or Utility Installations that 
Lessee shall desire to make and which require the consent of the Lessor shall 
be presented to Lessor in written form with detailed plans. 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 be in compliance with all Applicable Requirements. 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 $2,500.00 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)     LIEN PROTECTION. Lessee shall pay when due all claims 
for labor or materials furnished or alleged to have been furnished to or for 
Lessee at or for use on the Premises, which claims are or may be secured by 
any mechanic's or materialmen's lien against the Premises 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 
attorneys' 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 and to cause Lessee to become the owner thereof as hereinafter 
provided in this Paragraph 7.4, all Alterations and Utility Installations 
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 the 
Premises and be surrendered with the Premises by Lessee.

               (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 that their installation may have been consented to by Lessor. 
Lessor may require the removal at any time of all or any part of any 
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, 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 herein, 
the Premises, as surrendered, shall include the Alterations and 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 Lessee-Owned Alterations and 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
Requirements and/or good 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 OF PREMIUM INCREASES. 

               (a)     As used herein, the term "INSURANCE COST INCREASE" is 
defined as any increase in the actual cost of the insurance applicable to the 
Building and required to be carried by Lessor pursuant to Paragraphs 8.2(b), 
8.3(a) and 8.3(b), ("REQUIRED INSURANCE"), over and above the Base Premium, 
as hereinafter defined, calculated on an annual basis. "Insurance Cost 
Increase" shall include, but not be limited to, requirements of the holder of 
a mortgage or deed of trust covering the Premises, increased valuation of the 
Premises, and/or a general premium rate increase. The term "Insurance Cost 
Increase" shall not, however, include any premium increases resulting from 
the nature of the occupancy of any other lessee of the Building. If the 
parties insert a dollar amount in Paragraph 1.9, such amount shall be 
considered the "BASE PREMIUM." If a dollar amount has not been inserted in 
Paragraph 1.9 and if the Building has been previously occupied during the 
twelve (12) month period immediately preceding the Commencement Date, the 
"Base Premium" shall be the annual premium applicable to such twelve (12) 
month period. If the Building was not fully occupied during such twelve (12) 
month period, the "Base Premium" shall be the lowest annual premium 
reasonably obtainable for the Required Insurance as of the Commencement Date, 
assuming the most nominal use possible of the Building. In no event, however, 
shall Lessee be responsible for any portion of the premium cost attributable 
to liability insurance coverage in excess of $1,000,000 procured under 
Paragraph 8.2(b).

               (b)     Lessee shall pay any Insurance Cost Increase to Lessor 
pursuant to Paragraph 4.2. Premiums for policy periods commencing prior to, 
or extending beyond, the term of this Lease shall be prorated to coincide 
with the corresponding Commencement Date or Expiration Date. 

       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, Lessor and any Lender(s) whose names have been 
provided to Lessee in writing (as additional insureds) against claims for 
bodily injury, personal injury and property damage based upon, involving or 
arising out of the ownership, use, occupancy or maintenance of the Premises 
and all areas appurtenant thereto. Such insurance shall be on an occurrence 
basis providing single limit coverage in an amount not less than $1,000,000 
per occurrence with an "Additional Insured--Managers or Lessors of Premises" 
endorsement and contain the "Amendment of the Pollution Exclusion" 
endorsement for damage caused by heat, smoke or fumes from a hostile fire. 
The policy shall not contain any intra-insured exclusions as between insured 
persons or organizations, but shall include coverage for liability assumed 
under this Lease as an "INSURED CONTRACT" for the performance of Lessee's 
indemnity obligations under this Lease. The limits of said insurance 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. 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. 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 any Lender(s), insuring against 
loss or damage to the Premises. Such insurance shall be for full replacement 
cost, as the same shall exist from time to time, or the amount required by 
any Lender(s), 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. Lessee-Owned Alterations and Utility Installations, Trade 
Fixtures and Lessee's personal property shall be insured by Lessee pursuant 
to Paragraph 8.4. If the coverage is available and commercially appropriate, 
Lessor's policy or policies shall insure against all risks of direct physical 
loss or damage (except the perils of flood and/or earthquake unless required 
by a Lender or included in the Base Premium), 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 Building 
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 loss, 
but not including plate glass insurance. Said policy or policies shall also 
contain an agreed valuation provision in lieu of any co-insurance 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.

               (b)     RENTAL VALUE. Lessor shall also 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 any Lender(s), insuring the loss of the full 
rental and other charges payable by all lessees of the Building to Lessor for 
one year (including all Real Property Taxes, insurance costs, all Common Area 
Operating Expenses and any scheduled rental increases). Said insurance may 
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 
co-insurance clause, and the amount of coverage shall be adjusted annually to 
reflect the projected rental income, Real Property Taxes, insurance premium 
costs and other expenses, if any, otherwise payable, for the next 12-month 
period. Common Area Operating Expenses shall include any deductible amount in 
the event of such loss.

               (c)     ADJACENT PREMISES. Lessee shall pay for any increase in
the premiums for the property insurance of the Building and for the Common 
Areas or other buildings in the Industrial Center if said increase is caused by
Lessee's acts, omissions, use or occupancy of the Premises.


                                                                INITIALS:  TF

               (d)     LESSEE'S IMPROVEMENTS. Since Lessor is the Insuring 
Party, 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.

       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, Trade Fixtures and 
Lessee-Owned Alterations and Utility Installations in, on, or about the 
Premises similar in coverage to that carried by Lessor as the Insuring Party 
under Paragraph 8.3(a). Such insurance shall be full replacement cost 
coverage with a deductible not to exceed $1,000 per occurrence. The proceeds 
from any such insurance shall be used by Lessee for the replacement of 
personal property and the restoration of Trade Fixtures and Lessee-Owned 
Alterations and Utility Installations. Upon request from Lessor, Lessee 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, 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. Lessee shall cause to be 
delivered to Lessor, within seven (7) days after the earlier of the Early 
Possession Date or the Commencement Date, certified copies of, or 
certificates evidencing the existence and amounts of, the insurance required 
under Paragraph 8.2(a) and 8.4  No such policy shall be cancelable or subject 
to modification except after thirty (30) days' prior written notice to 
Lessor.  Lessee shall at least thirty (30) days prior to the expiration of 
such policies, furnish Lessor with evidence of renewals or "insurance 
binders" evidencing renewal thereof, or Lessor may order such insurance and 
charge the cost thereof to Lessee, which amount shall be payable by Lessee to 
Lessor upon demand.

       8.6     WAIVER OF SUBROGATION. Without affecting any other rights or 
remedies, Lessee and Lessor each hereby release and relieve the other, and 
waive their entire right to recover damages (whether in contract or in tort) 
against the other, for loss or damage to their 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.  Lessor and Lessee agree to have their 
respective insurance companies issuing property damage insurance waive any 
right to subrogation that such companies may have against Lessor or Lessee, 
as the case may be, so long as the insurance is not invalidated thereby.

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

       8.8     EXEMPTION OF LESSOR FROM LIABILITY. Lessor shall not be 
liable for injury or damage to the person or goods, wares, merchandise or 
other property of Lessee, Lessee's employees, contractors, invitees, 
customers, or any other person in or about the Premises, whether such damage 
or injury is caused 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 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, 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 lessee of Lessor nor 
from the failure by Lessor to enforce the provisions of any other lease in 
the Industrial Center.  Notwithstanding Lessor's negligence or breach of this 
Lease, Lessor shall under no circumstances be liable for injury to Lessee's 
business or for any loss of income or profit therefrom.

9.     DAMAGE OR DESTRUCTION.

       9.1     DEFINITIONS.

               (a)     "PREMISES PARTIAL DAMAGE" shall mean damage or
destruction to the Premises, other than Lessee-Owned Alterations and Utility
Installations, the repair cost of which damage or destruction is less than fifty
percent (50%) of the then Replacement Cost (as defined in Paragraph 9.1(d)) of
the Premises (excluding Lessee-Owned Alterations and Utility Installations and
Trade Fixtures) immediately prior to such damage or destruction.

               (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 fifty
percent (50%) or more of the then Replacement Cost of the Premises (excluding
Lessee-Owned Alterations and Utility Installations and Trade Fixtures)
immediately prior to such damage or destruction.  In addition, damage or
destruction to the Building, other than Lessee-Owned Alterations and Utility
Installations and Trade Fixtures of any lessees of the Building, the cost of
which damage or destruction is fifty percent (50%) or more of the then
Replacement Cost (excluding Lessee-Owned Alterations and Utility Installations
and Trade Fixtures of any lessees of the Building) of the Building shall, at the
option of Lessor, be deemed to be Premises Total Destruction.

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

               (d)     "REPLACEMENT COST" shall mean the cost to repair or
rebuild the improvements owned by Lessor at the time of the occurrence to their
condition existing immediately prior thereto, including demolition, debris
removal and upgrading required by the operation of applicable 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     PREMISES PARTIAL DAMAGE--INSURED LOSS. If 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.  In the event, however, 
that there is a shortage of insurance proceeds and such shortage is due to 
the fact that, by reason of the unique nature of the improvements in the 
Premises, 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, Lessor 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 
thereof within said period, Lessor may nevertheless elect by written notice 
to Lessee within ten (10) days thereafter to make 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 Lessor does 
not receive such funds or assurance within such ten (10) day period, and if 
Lessor does not so elect to restore and repair, 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 DAMAGE--UNINSURED LOSS. If 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), 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 date 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 such commitment from Lessee.  In 
such event this Lease shall continue in full force and effect, and Lessor 
shall proceed to make such repairs as soon as reasonably possible after the 
required funds are available.  If Lessee does not give such notice and 
provide the funds or assurance thereof within the times specified above, this 
Lease shall terminate as of the date specified in Lessor's notice of 
termination.

       9.4     TOTAL DESTRUCTION. Notwithstanding any other provision hereof,
if 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 9.7.

       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 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 (a) exercising such option, and (b) providing Lessor with any shortage
in insurance proceeds  (or adequate assurance thereof) needed to make the
repairs on or before the earlier of (i) the date which is ten (10) days after
Lessee's receipt of Lessor's written notice purporting to terminate this Lease,
or (ii) the day prior to the date upon which such option expires.  If Lessee
duly exercises such option during such period and provides Lessor with funds (or
adequate assurance thereof) to cover any shortage in insurance proceeds, Lessor
shall, at Lessor's expense repair such damage as soon as reasonably possible and
this Lease shall continue in full force and effect.  If Lessee fails to exercise
such option and provide such funds or assurance during such period, then this
Lease shall terminate as of the date set forth in the first sentence of this
Paragraph 9.5.

       9.6     ABATEMENT OF RENT; LESSEE'S REMEDIES.

               (a)     In the event of (i) Premises Partial Damage or (ii) 
Hazardous Substance Condition for which Lessee is not legally responsible, 
the Base Rent, Common Area Operating Expenses and other charges, if any, 
payable by Lessee hereunder for the period during which such damage or 
condition, its repair, remediation or restoration continues, shall be abated 
in proportion to the degree to which Lessee's use of the Premises is 
impaired, but not in excess of proceeds from insurance required to be carried 
under Paragraph 8.3(b). Except for abatement of Base Rent, Common Area 
Operating Expenses 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 damage, destruction, repair, remediation or restoration.


                                                                INITIALS:  TF

               (b)     If Lessor shall be obligated to repair or restore the 
Premises under the provisions of this Paragraph 9 and shall not commence, in 
a substantial and meaningful way, the repair or restoration of the Premises 
within ninety (90) days after such obligation shall accrue, Lessee may, at 
any time prior to the commencement of such repair or restoration, give 
written notice to Lessor and to any Lenders of which Lessee has actual notice 
of Lessee's election to terminate this Lease on a date not less than sixty 
(60) days following the giving of such notice.  If Lessee gives such notice 
to Lessor and such Lenders and such repair or restoration is not commenced 
within thirty (30) days after receipt of such notice, this Lease shall 
terminate as of the date specified in said notice.  If Lessor or a Lender 
commences the repair or restoration of the Premises within thirty (30) days 
after the receipt of such notice, this Lease shall continue in full force and 
effect.  "COMMENCE" as used in this Paragraph 9.6 shall mean either the 
unconditional authorization of the preparation of the required plans, or the 
beginning of the actual work on the Premises, whichever occurs first.

       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 Requirements and this Lease shall continue in full force and effect,
but subject to Lessor's rights under Paragraph 6.2(c) and 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 date 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 excess costs of (a) investigation and
remediation of such Hazardous Substance Condition to the extent required by
Applicable Requirements, over (b) 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 said commitment by Lessee.  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 after the
required funds are available.  If Lessee does not give such notice and provide
the required funds or assurance thereof within the time period specified above,
this Lease shall terminate as of the date specified in Lessor's notice of
termination.

       9.8     TERMINATION--ADVANCE PAYMENTS. Upon termination of this 
Lease pursuant to this Paragraph 9, Lessor shall return to Lessee any advance 
payment made by Lessee to Lessor and 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     WAIVER OF STATUTES. Lessor and Lessee agree that the terms of
this Lease shall govern the effect of any damage to or destruction of the
Premises and the Building with respect to the termination of this Lease and
hereby waive the provisions of any present or future statute to the extent it is
inconsistent herewith.

10.    REAL PROPERTY TAXES.

       10.1    PAYMENT OF TAXES. Lessor shall pay the Real Property Taxes, 
as defined in Paragraph 10.2(a), applicable to the Industrial Center, and 
except as otherwise provided in Paragraph 10.3, any increases in such amounts 
over the Base Real Property Taxes shall be included in the calculation of 
Common Area Operating Expenses in accordance with the provisions of Paragraph 
4.2.

       10.2    REAL PROPERTY TAX DEFINITIONS.  

               (a)     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 Industrial Center 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 Industrial Center or any portion thereof, 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 
Industrial Center 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.  

               (b)     As used herein, the term "BASE REAL PROPERTY TAXES" 
shall be the amount of Real Property Taxes, which are assessed against the 
Premises, Building or Common Areas in the calendar year during which the 
Lease is executed. In calculating Real Property Taxes for any calendar year, 
the Real Property Taxes for any real estate tax year shall be included in the 
calculation of Real Property Taxes for such calendar year based upon the 
number of days which such calendar year and tax year have in common.

       10.3    ADDITIONAL IMPROVEMENTS. Common Area Operating Expenses shall
not include Real Property Taxes specified in the tax assessor's records and work
sheets as being caused by additional improvements placed upon the Industrial
Center by other lessees or by Lessor for the exclusive enjoyment of such other
lessees.  Notwithstanding Paragraph 10.1 hereof, Lessee shall, however, pay to
Lessor at the time Common Area Operating Expenses are payable under Paragraph
4.2, the entirety of any increase in Real Property Taxes if assessed solely by
reason of Alterations, Trade Fixtures or Utility Installations placed upon the
Premises by Lessee or at Lessee's request.

       10.4    JOINT ASSESSMENT. If the Building is not separately assessed,
Real Property Taxes allocated to the Building shall be an equitable proportion
of the Real Property Taxes for all of the land and improvements included within
the tax parcel assessed, such proportion to be determined by Lessor from the
respective valuations 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.

       10.5    LESSEE'S PROPERTY TAXES. Lessee shall pay prior to delinquency
all taxes assessed against and levied upon Lessee-Owned Alterations and Utility
Installations, Trade Fixtures, furnishings, equipment and all personal property
of Lessee contained in the Premises or stored within the Industrial Center.
When possible, Lessee shall cause its Lessee-Owned Alterations and Utility
Installations, Trade Fixtures, furnishings, equipment and all other personal
property to be assessed and billed separately from the real property of Lessor.
If any of Lessee's said property shall be assessed with Lessor's real property,
Lessee shall pay Lessor the taxes attributable to Lessee's property within ten
(10) days after receipt of a written statement setting forth the taxes
applicable to Lessor's property.

11.    UTILITIES. Lessee shall pay directly for all utilities and services
supplied to the Premises, including but not limited to electricity, telephone,
security, gas and cleaning of the Premises, together with any taxes thereon.  If
any such utilities or services are not separately metered to the Premises or
separately billed to the Premises, Lessee shall pay to Lessor a reasonable
proportion to be determined by Lessor of all such charges jointly metered or
billed with other premises in the Building, in the manner and within the time
periods set forth in Paragraph 4.2(d).

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,
"assign") or sublet all or any part of Lessee's interest in this Lease or in the
Premises without Lessor's prior written consent given under and subject to the
terms of Paragraph 36.

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

               (c)     The involvement of Lessee or its assets in any 
transaction or series of transactions (by way of merger, sale, acquisition, 
financing, refinancing, transfer, leveraged buy-out or otherwise), whether or 
not a formal assignment or hypothecation of this Lease or Lessee's assets 
occurs, which results or will result in a reduction of the Net Worth of 
Lessee, as hereinafter defined, by an amount equal to or greater than 
twenty-five percent (25%) of such Net Worth of Lessee as it was represented 
to Lessor at the time of full execution and delivery 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, or a 
non-curable Breach without the necessity of any notice and grace period.  If 
Lessor elects to treat such unconsented to assignment or subletting as a 
non-curable 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 for the Premises to the greater of the then 
fair market rental value of the Premises, as reasonably determined by Lessor, 
or one hundred ten percent (110%) of the Base Rent then in effect.  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 rental 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 as reasonably 
determined by Lessor (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, (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 rental bears to the Base Rent in 
effect immediately prior to the adjustment specified in Lessor's Notice.

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

       12.2    TERMS AND CONDITIONS APPLICABLE TO ASSIGNMENT AND SUBLETTING.

               (a)     Regardless of Lessor's consent, 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, nor (iii) alter the primary
liability of Lessee for the payment of Base Rent and other sums due Lessor
hereunder or for the performance of any other obligations to be performed by
Lessee under this Lease.

               (b)     Lessor may accept any rent or performance of Lessee's 
obligations from any person other than Lessee pending approval or disapproval 
of an assignment.  Neither a delay in the approval or disapproval of such 
assignment nor the acceptance of any rent for 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 of subletting by the
assignee or sublessee.  However, Lessor may consent to subsequent sublettings
and assignments of the sublease or any amendments or modifications thereto
without notifying Lessee or anyone else liable under this Lease or the sublease
and without obtaining their consent, and such action shall not relieve such
persons from liability under this Lease or the sublease.

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

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

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

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

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

       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 the foregoing provision 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 such 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 under a sublease approved by Lessor 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), $350.00 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" by 
Lessee is defined as a failure by Lessee to observe, comply with or perform 
any of the terms, covenants, conditions or rules applicable to Lessee under 
this Lease. A "BREACH" by Lessee 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, and 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, Lessee's Share of 
Common Area Operating Expenses, or any other monetary payment required to be 
made by Lessee hereunder 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 
Requirements per Paragraph 6.3, (ii) the inspection, maintenance and service 
contracts required under Paragraph 7.1(b), (iii) the rescission of an 
unauthorized assignment or subletting per Paragraph 12.1, (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 13.1(a), (b) or (c), 
above, where such Default continues for a period of thirty (30) days after 
written notice thereof by or on behalf of Lessor to Lessee; provided, 
however, that if the nature of Lessee's Default is such that more than thirty 
(30) days are reasonably required for its cure, then it shall not be deemed 
to be a Breach of this Lease by Lessee if Lessee commences such cure within 
said thirty (30) day period and thereafter diligently prosecutes such cure to 
completion.

               (e)     The occurrence of any of the following events: (i) the 
making by Lessee of any general arrangement or assignment for the benefit of 
creditors; (ii) Lessee's becoming a "debtor" as defined in 11 U.S. Code 
Section 101 or any successor statute thereto (unless, in the case of a 
petition filed against Lessee, the same is dismissed within sixty (60) days); 
(iii) the appointment of a trustee or receiver to take possession of 
substantially all of Lessee's assets located at the Premises or of Lessee's 
interest in this Lease, where possession is not restored to Lessee within 
thirty (30) days; or (iv) the attachment, execution or other judicial seizure 
of substantially all of Lessee's assets located at the Premises or of 
Lessee's interest in this Lease, where such seizure is not discharged within 
thirty (30) days; provided, however, in the event that any provision of this 
Subparagraph 13.1(e) is contrary to any applicable law, such provision shall 
be of no force or effect, and shall not affect the validity of the remaining 
provisions.

               (f)     The discovery by Lessor that any financial statement 
of Lessee or of any Guarantor, given to Lessor by Lessee or any Guarantor, 
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 assurances of 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 own option, may require all further 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 any leasing 
commission paid by Lessor in connection with this Lease applicable to the 
unexpired term of this Lease. The worth at the time of award of the amount 
referred to in provision (iii) of the immediately preceding sentence shall be 
computed by discounting such amount at the discount rate of the Federal 
Reserve Bank of San Francisco or the Federal Reserve Bank District in which 
the Premises are located 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 
13.2. If termination of this Lease is obtained

                                                                INITIALS:  TF

                                                                           PS

<PAGE>

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 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 Subparagraph 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 Subparagraph 13.1(b), (c) or (d). In such 
case, the applicable grace period 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 (2) 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 recover the rent as it becomes due, provided Lessee has the right to
sublet or assign, subject only to reasonable limitations. Lessor and Lessee
agree that the limitations on assignment and subletting in this Lease 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 this
Lease, shall not constitute a termination of the Lessee's right to possession.

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

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

       13.3    INDUCEMENT RECAPTURE IN EVENT OF BREACH. Any agreement by 
Lessor for free or abated rent or other charges applicable to the Premises, 
or for the giving or paying by Lessor to or for Lessee of any cash or other 
bonus, inducement or consideration for Lessee's entering into this Lease, all 
of which concessions are hereinafter referred to as "INDUCEMENT PROVISIONS" 
shall be deemed conditioned upon Lessee's full and faithful performance of 
all of the terms, covenants and conditions of this Lease to be performed or 
observed by Lessee during the term hereof as the same may be extended. Upon 
the occurrence of a Breach (as defined in Paragraph 13.1) of this Lease by 
Lessee, any such Inducement Provision shall automatically be deemed deleted 
from this Lease and of no further force or effect, and any rent, other 
charge, bonus, inducement or consideration theretofore abated, given or paid 
by Lessor under such an Inducement Provision shall be immediately due and 
payable by Lessee to Lessor, 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 13.3 shall not be deemed a waiver 
by Lessor of the provisions of this Paragraph 13.3 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 deed of trust covering 
the Premises. Accordingly, if any installment of rent or other sum due from 
Lessee shall not be received by Lessor or Lessor's designee within ten (10) 
days after such amount shall be due, then, without any requirement for notice 
to Lessee, Lessee shall pay to Lessor a late charge equal to six percent (6%) 
of such overdue amount.  The parties hereby agree that such late charge 
represents a fair and reasonable estimate of the costs Lessor will incur by 
reason of late payment by Lessee. Acceptance of such late charge by Lessor 
shall in no event constitute a waiver of Lessee's Default or Breach with 
respect to such overdue amount, nor prevent Lessor from exercising any of the 
other rights and remedies granted hereunder. In the event that a late charge 
is payable hereunder, whether or not collected, for three (3) consecutive 
installments of Base Rent, then notwithstanding Paragraph 4.1 or any other 
provision of this Lease to the contrary, Base Rent shall, at Lessor's option, 
become due and payable quarterly in advance.

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

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 portion of the Common Areas designated for Lessee's parking, is 
taken by condemnation, Lessee may, at Lessee's option, to be exercised in 
writing within ten (10) days after Lessor shall have given Lessee written 
notice of such taking (or in the absence of such notice, within ten (10) days 
after the condemning authority shall have taken possession) terminate this 
Lease as of the date the condemning authority takes such possession. If 
Lessee does not terminate this Lease in accordance with the foregoing, this 
Lease shall remain in full force and effect as to the portion of the Premises 
remaining, except that the Base Rent shall be reduced in the same proportion 
as the rentable floor area of the Premises taken bears to the total rentable 
floor area of the Premises. No reduction of Base Rent shall occur if the 
condemnation does not apply to any portion of the Premises. 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 of 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 Lessee's Share of the legal 
and other expenses incurred by Lessor in the condemnation matter, repair any 
damage to the Premises caused by such condemnation authority. Lessee shall be 
responsible for the payment of any amount in excess of such net severance 
damages required to complete such repair.

15.    BROKERS' FEES.

       15.1    PROCURING CAUSE. The Broker(s) named in Paragraph 1.10 is/are
the procuring cause of this Lease.

       15.2    ADDITIONAL TERMS. Unless Lessor and Broker(s) have otherwise
agreed in writing, Lessor agrees that: (a) if Lessee exercises any Option (as
defined in Paragraph 39.1) granted under this Lease or any Option subsequently
granted, or (b) if Lessee acquires any rights to the Premises or other premises
in which Lessor has an interest, or (c) if Lessee remains in possession of the
Premises with the consent of Lessor after the expiration of the term of this
Lease after having failed to exercise an Option, or (d) if said Brokers are the
procuring cause of any other lease or sale entered into between the Parties
pertaining to the Premises and/or any adjacent property in which Lessor has 
an interest, or (e) if Base Rent is increased, whether by agreement or 
operation of an escalation clause herein, then as to any of said 
transactions, Lessor shall pay said Broker(s) a fee in accordance with the 
schedule of said Broker(s) in effect at the time of the execution of this 
Lease.

       15.3    ASSUMPTION OF OBLIGATIONS. Any buyer or transferee of Lessor's
interest in this Lease, whether such transfer is by agreement or by operation of
law, shall be deemed to have assumed Lessor's obligation under this Paragraph
15. Each Broker shall be an intended third party beneficiary of the provisions
of Paragraph 1.10 and of this Paragraph 15 to the extent of its interest in any
commission arising from this Lease and may enforce that right directly against
Lessor and its successors.

       15.4    REPRESENTATIONS AND WARRANTIES. 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 as named in Paragraph 1.10(a) 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 Broker(s) 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, and/or 
attorney's fees reasonably incurred with respect thereto.

16.    TENANCY AND FINANCIAL STATEMENTS.

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

17.    LESSOR'S LIABILITY. The term "LESSOR" as used herein shall mean the
owner or owners at the time in question of the fee title to the Premises. 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 15.3, upon such transfer or
assignment and delivery of the Security Deposit, as aforesaid, the prior Lessor
shall be relieved of all liability with respect to the obligations and/or
covenants under this Lease thereafter to be performed by the Lessor. Subject to
the foregoing, the obligations and/or covenants in this Lease to be performed by
the Lessor shall be binding only upon the Lessor as hereinabove defined.

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

19.    INTEREST ON PAST-DUE OBLIGATIONS. Any monetary payment due Lessor
hereunder, other than late charges, not received by Lessor within ten (10) days
following the date on which it was due, shall bear interest from the date due at
the prime rate charged by the largest state chartered bank in the state in which
the Premises are located plus four percent (4%) per annum, but not exceeding the
maximum rate allowed by law, in addition to the potential 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. Each Broker shall be an 
intended third party beneficiary of the provisions of this Paragraph 22.

23.    NOTICES.

       23.1    NOTICE REQUIREMENTS. 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 during normal business hours, 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 as 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 of parties at such addresses as Lessor
may from time to time hereafter designate by written notice to Lessee.

       23.2    DATE OF NOTICE. Any notice sent by registered or certified mail,
return receipt requested, shall be deemed given on the date of delivery shown on
the receipt card, or if no delivery date is shown, the postmark thereon. If sent
by regular mail, the notice shall be deemed given forty-eight (48) hours after
the same is addressed as required herein and mailed with postage prepaid.
Notices delivered by United States Express Mail or overnight courier that
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 or facsimile confirmation of
receipt of the transmission thereof, provided a copy is also delivered via
delivery or mail. If notice is received on a Saturday or a Sunday or a 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 any other term, covenant or condition hereof. Lessor's
consent to, or approval of, any such 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 Default or Breach by
Lessee of any provision hereof. 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. In the event that Lessee holds over in violation of this Paragraph
26 then the Base Rent payable from and after the time of the expiration or
earlier termination of this Lease shall be increased to two hundred percent
(200%) of the Base Rent applicable during the month immediately preceding such
expiration or earlier termination. Nothing contained herein shall be construed
as a consent by Lessor to any holding over by Lessee.

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

28.    COVENANTS AND CONDITIONS. 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 
pursuant to Paragraph 13.5. If any Lender shall elect to have this Lease 
and/or any Option granted hereby superior to the lien of its Security Device 
and shall give written notice thereof to Lessee, this Lease and such Options 
shall be deemed prior to such Security Device, notwithstanding the relative 
dates of the documentation or recordation thereof.

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

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

       30.4    SELF-EXECUTING. The agreements contained in this Paragraph 30
shall be effective without the execution of any further documents; provided,
however, that upon written request from Lessor or a Lender in connection with a
sale, financing or refinancing of 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.    ATTORNEYS' 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) in any such proceeding, action, or appeal thereon, shall
be entitled to reasonable attorneys' fees. Such fees may be awarded in the same
suit or recovered in a separate suit, whether or not such action or proceeding
is pursued to decision or judgment. The term "Prevailing Party" shall include,
without limitation, a Party or Broker who substantially obtains or defeats the
relief sought, as the case may be, whether by compromise, settlement, judgment,
or the abandonment by the other Party or Broker of its claim or defense. The
attorneys' fee award shall not be computed in accordance with any court fee
schedule, but shall be such as to fully reimburse all attorneys' fees reasonably
incurred. Lessor shall be entitled to attorneys' fees, costs and expenses
incurred in 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. Broker(s) shall be intended
third party beneficiaries of this Paragraph 31.

32.    LESSOR'S ACCESS; SHOWING PREMISES; REPAIRS. Lessor and Lessor's agents
shall have the right to enter the Premises at any time, in the case of an
emergency, and otherwise at reasonable times for the purpose of showing the same
to prospective purchasers, lenders, or lessees, and making such alterations,
repairs, improvements or additions to the Premises or to the Building, 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 eighty (180) 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 exterior of the Premises
or the Building, 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 so long as such signs are in a location designated by
Lessor and comply with Applicable Requirements and the signage criteria
established for the Industrial Center by Lessor. 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 of the Building, and the right to install advertising signs on the
Building, including the roof, which do not unreasonably interfere with the
conduct of Lessee's business; Lessor shall be entitled to all revenues from such
advertising signs.

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' and 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, shall be paid by Lessee to Lessor upon receipt of an
invoice and supporting documentation therefor. In addition to the deposit
described in Paragraph 12.2(e), 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. 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 
impositions 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    FORM OF GUARANTY. 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 such 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 required in
Paragraph 16.


                                                                INITIALS:  TF

       37.2    ADDITIONAL OBLIGATIONS OF GUARANTOR. 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 resolution of its board of directors 
authorizing the making of such guaranty, together with a certificate of 
incumbency showing the signatures 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 
confirmation that the guaranty is still in effect.

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

39.    OPTIONS.

       39.1    DEFINITION. As used in this Lease, 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 of 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 separate Defaults 
under Paragraph 13.1 during the twelve (12) month period immediately 
preceding the exercise of the Option, whether or not the Defaults are cured.

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

               (c)     All rights of Lessee under the provisions of an Option 
shall terminate and be of no further force or effect, notwithstanding 
Lessee's due and timely exercise of the Option, if, after such exercise and 
during the term of this Lease, (i) Lessee fails to pay to Lessor a monetary 
obligation of Lessee for a period of thirty (30) days after such obligation 
becomes due (without any necessity of Lessor to give notice thereof to 
Lessee), or (ii) Lessor gives to Lessee three (3) or more notices of separate 
Defaults 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.    RULES AND REGULATIONS. Lessee agrees that it will abide by, and keep 
and observe all reasonable rules and regulations ("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 the Building and the Industrial Center and their invitees.

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 the right, from time to time, to grant, 
without the consent or joinder of Lessee, such easements, rights of way, 
utility raceways, and dedications that Lessor deems necessary, and to cause 
the recordation of parcel maps and restrictions, so long as such easements, 
rights of way, utility raceways, dedications, maps and restrictions do not 
reasonably 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 either Lessor or Lessee or 
Lessor's agent or Lessee's agent and submission of same to Lessee or Lessor 
shall not be deemed an offer to lease.  This Lease is not intended to be 
binding until executed and delivered by all Parties hereto.

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

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

          Brokers have no specific expertise with respect to making an

          to the disposal of hazardous or toxic substances or waste, and

     B.   Brokers have not made an independent investigation of the premises or
          determination with respect to the physical and environmental condition
          of the premises, including without limitation, the existence or
          non-existence of any underground tanks, dumps, piping, toxic or
          hazardous substances on the premises.  Brokers urge all parties to
          obtain independent legal and technical advice with respect to the
          physical and environmental condition of the premises.  The parties
          each agree that it will rely solely on its own investigation and/or
          that of a licensed professional specializing in these areas and not of
          the Brokers.

     C.   Brokers do not represent and warrant the accuracy or completeness of

     WHEREAS, All Phase Telecommunication, Inc., hereinafter referred to as
"Lessor", and The Quicksilver Group, Inc., hereinafter referred to as "Lessee",
are about to execute a document entitled "Lease" dated October 20, 1995
concerning the premises commonly known as 10061-B Bubb Road, Cupertino wherein
Lessor will lease the premises to Lessee, and

     WHEREAS, Mr. Thomas Minick and Mr. Todd Fitzwater hereinafter referred to
as "Guarantors" have a financial interest in Lessee, and

     WHEREAS, Lessor would not execute the Lease if Guarantors did not execute
and deliver to Lessor this Guarantee of Lease.

     NOW THEREFORE, for and in consideration of the execution of the foregoing
Lease by Lessor and as a material inducement to Lessor to execute said Lease,
Guarantors hereby jointly, severally, unconditionally and irrevocably guarantee
the prompt payment by Lessee of all rentals and all other sums payable by Lessee
under said Lease and the faithful and prompt performance by Lessee of each and
every one of the terms, conditions and covenants of said Lease to be kept and
performed by Lessee.

     It is specifically agreed and understood that the terms of the foregoing
Lease may be altered, affected, modified or changed by agreement between Lessor
and Lessee, or by a course of conduct, and said Lease may be assigned by Lessor
or any assignee of Lessor without consent or notice to Guarantors and that this
Guaranty shall thereupon and thereafter guarantee the performance of said Lease
as so changed, modified, altered or assigned.

     This Guaranty shall not be released, modified or affected by failure or
delay on the part of Lessor to enforce any of the rights or remedies of the
Lessor under said Lease, whether pursuant to the terms thereof or at law or in
equity.

     No notice of default need be given to Guarantors, it being specifically
agreed and understood that the guarantee of the undersigned is a continuing
guarantee under which Lessor may proceed forthwith and immediately against
Lessee or against Guarantors following any breach or default by Lessee or for
the enforcement of any rights which Lessor may have as against Lessee pursuant
to or under the terms of the within Lease or at law or in equity.

     Lessor shall have the right to proceed against Guarantors hereunder
following any breach or default by Lessee without first proceeding against
Lessee and without previous notice to or demand upon either Lessee or
Guarantors.

     Guarantors hereby waive (a) notice of acceptance of this Guaranty, (b) 
demand of payment, presentation and protest, (c) all right to assert or plead 
any statute of limitations as to or relating to this Guaranty and the Lease, 
(d) any right to require the Lessor to proceed against the Lessee or any 
other Guarantor or any other person or entity liable to Lessor, (e) any right 
to require Lessor to apply to any default any security deposit or other 
security it may hold under the Lease, (f) any right to require Lessor to 
proceed under any other remedy Lessor may have before proceeding against 
Guarantors, (g) any right of subrogation.

     Guarantors do hereby subrogate all existing or future indebtedness of
Lessee to Guarantors to the obligations owed to Lessor under the Lease and this
Guaranty.

     Any married woman who signs this Guaranty expressly agrees that recourse
may be had against her separate property for all of her obligations hereunder.

     The obligations of Lessee under the Lease to execute and deliver estoppel
statements and financial statements, as therein provided, shall be deemed to
also require the Guarantors hereunder to do and provide the same relative to
Guarantors.

     The term "Lessor" whenever hereinabove used refers to and means the Lessor
in the foregoing Lease specifically named and also any assignee of said Lessor,
whether by outright assignment or by assignment for security, and also any
successor to the interest of said Lessor or of any assignee in such Lease or any
part thereof, whether by assignment or otherwise.  So long as the Lessor's
interest in or to the leased premises or the rents, issues and profits
therefrom, or in, to or under said Lease, are subject to any mortgage or deed of
trust or assignment for security, no acquisition by Guarantors of the Lessor's
interest in the leased premises or under said Lease shall affect the continuing
obligation of Guarantors under this Guaranty which shall nevertheless continue
in full force and effect for the benefit of the mortgagee, beneficiary, trustee
or assignee under such mortgage, deed of trust or assignment, of any purchase at
sale by judicial foreclosure or under private power of sale, and of the
successors and assigns of any such mortgagee, beneficiary, trustee, assignee or
purchaser.

     The term "Lessee" whenever hereinabove used refers to and means the Lessee
in the foregoing Lease specifically named and also any assignee or sublessee of
said Lease and also any successor to the interests of said Lessee, assignee or

hereunder to enforce the obligation of Guarantors hereunder, the unsuccessful
party in such action shall pay to the prevailing party therein a reasonable
attorney's fee which shall be fixed by the court.

    THIS INDENTURE OF LEASE made and entered into on the Execution Date as 
stated in Exhibit 1 and between the Landlord and the Tenant named in Exhibit 
1.

Landlord does hereby demise and lease to Tenant, and Tenant does hereby hire 
and take from Landlord, the premises hereinafter mentioned and described 
(hereinafter referred to as "premises"), upon and subject to the covenants, 
agreements, terms, provisions and conditions of this Lease for the term 
hereinafter stated:

1.  REFERENCE DATA

    Each reference in this Lease to any of the terms and titles contained 
in any Exhibit attached to this Lease shall be deemed and construed to 
incorporate the data stated under that term or title in such Exhibit.

2.  DESCRIPTION OF DEMISED PREMISES

    2.1    DEMISED PREMISES. The premises are that portion of the Building as 
described in Exhibit 1 (as the same may from time to time be constituted 
after changes therein, additions thereto and eliminations therefrom pursuant to
rights of Landlord hereinafter reserved) and is hereinafter referred to as 
"Building", substantially as shown hatched or outlined on the Lease Plan 
(Exhibit 2) hereto attached and incorporated by reference as a part hereof. 
Landlord reserves the right, at its own cost and expense, upon not less than 
thirty (30) days' notice, to require Tenant to relocate its premises to an 
area of substantially equivalent size, construction and finish as designated 
by Landlord within the Building or another building owned by Landlord in the 
office park in which the Building is located. If, within thirty (30) days 
after Tenant's receipt of such notice, Landlord and Tenant have not agreed on 
space to which the premises are to be relocated or the timing of such 
relocation, Landlord, at its option, may either (i) rescind the relocation 
notice, in which case the Lease shall remain in full force and effect in 
accordance with its terms, or (ii) submit any dispute between the parties to 
arbitration pursuant to Article 29.5 hereof to determine whether the proposed 
relocation space is substantially equivalent.

    2.2    APPURTENANT RIGHTS. Tenant shall have, as appurtenant to the 
premises, rights to use in common, with others entitled thereto, subject to 
reasonable rules from time to time made by Landlord of which Tenant is given 
notice; (a) the common lobbies, hallways, stairways and elevators of the 
Building, serving the premises in common with others, (b) common walkways 
necessary for access to the Building, (c) if the premises include less than 
the entire rentable area of any floor, the common toilets and other common 
facilities of such floor, and (d) the common parking facilities adjacent to 
the Building in accordance with the provisions of this Article 2.2; and no 
other appurtenant rights or easements. Notwithstanding anything to the 
contrary herein or in the Lease contained, Landlord has no obligation to 
allow any particular telecommunication service provider to have access to the 
Building or to Tenant's premises. If Landlord permits such access, Landlord 
may condition such access upon the payment to Landlord by the service 
provider of fees assessed by Landlord in its sole discretion.

           As of the Execution Date of this Lease, there are approximately 
3.4 parking spaces in the parking areas designated for use by the tenants of 
the Building for every 1,000 square feet of Building Total Rentable Area (as 
defined in Exhibit 1). Nothing contained in the Lease shall prohibit or 
otherwise restrict Landlord from changing, from time to time, without notice 
to Tenant, the location, layout or type of such parking areas, provided that 
Landlord shall not substantially reduce the number of parking spaces 
available for such tenants' use. Subject to reasonable rules from time to 
time made by Landlord of which Tenant is given notice, Tenant shall have the 
right, in common with all other tenants of the Building, to use such parking 
areas, without charge, on a first-come, first-served basis.

    2.3    EXCLUSIONS AND RESERVATIONS. All the perimeter walls of the 
premises except the inner surfaces thereof, any balconies (except to the 
extent same are shown as part of the premises on the Lease Plan (Exhibit 2)), 
terraces or roofs adjacent to the premises, and any space in or adjacent to 
the premises used for shafts, stacks, pipes, conduits, wires and appurtenant 
fixtures, fan rooms, ducts, electric or other utilities, sinks or other 
Building facilities, and the use thereof, as well as the right of access 
through the 
                                      -1-

premises for the purposes of operation, maintenance, decoration and repair,

other provisions of this Lease or pursuant to law (which date for the 
termination of the terms hereof will hereafter be called "Termination Date"). 
Notwithstanding the foregoing, if the Termination Date as stated in Exhibit 1 
shall fall on other than the last day of a calendar month, said Termination 
Date shall be deemed to be the last day of the calendar month in which said 
Termination Date occurs.

           If the Term Commencement Date and the Termination Date are not 
determined at the time that a notice of lease has been executed by the 
parties, then each of the parties hereto agrees, upon demand of the other 
party after the Term Commencement Date and Termination Date have been 
determined, to join in the execution, in recordable form, of a statutory 
notice, memorandum, etc. of lease and/or written declaration in which shall 
be stated such Term Commencement Date and (if need be) the Termination Date. 
If this Lease is terminated before the term expires, then upon Landlord's 
request the parties shall execute, deliver and record an instrument 
acknowledging such fact and the date of termination of this Lease, and Tenant 
hereby appoints Landlord its attorney-in-fact in its name and behalf to 
execute such instrument if Tenant shall fail to execute and deliver such 
instrument after Landlord's request therefor within ten (10) days.

4.  READINESS FOR OCCUPANCY - ENTRY BY TENANT PRIOR TO TERM COMMENCEMENT DATE

    4.1    COMPLETION DATE - DELAYS. Subject to delay by causes beyond the 
reasonable control of Landlord or caused by the action or inaction of Tenant, 
Landlord shall use reasonable speed and diligence in the construction of the 
Building and to have the premises ready for Tenant's occupancy on the 
Specified Commencement Date. The failure to have the premises ready for 
Tenant's occupancy on the Specified Commencement Date shall in no way affect 
the validity of this Lease or the obligations of Tenant hereunder nor shall 
the same by construed in any way to extend the term of this Lease. If the 
premises are not ready for Tenant's occupancy within the meaning of Article 
4.2 hereof on the Specified Commencement Date, Tenant shall not have any 
claim against Landlord, and Landlord shall have no liability to Tenant, by 
reason thereof.

    4.2    WHEN PREMISES DEEMED READY.


                                      -2-


<PAGE>

            (a)  The premises shall conclusively be deemed ready for Tenant's 
occupancy as soon as Landlord's Work, as defined in Paragraph (b) of this 
Article 4.2, has been substantially completed by Landlord insofar as is 
practicable in view of delays or defaults, if any, of Tenant or its 
contractors, as hereinafter specified, and the elevator, plumbing, air 
conditioning and electric facilities are initially substantially available to 
Tenant, in accordance with the obligations assumed by Landlord hereunder. 
Such facilities shall not be deemed to be unavailable if only minor or 
insubstantial details of construction, decoration or mechanical adjustments 
remain to be done. The premises shall not be deemed to be unready for 
Tenant's occupancy or incomplete if only minor or insubstantial details of 
construction, decoration or mechanical adjustments remain to be done in the 
premises or any part thereof, or if the delay in the availability of the 
premises for occupancy is (i) due to special work, changes, alterations or 
additions required or made by Tenant in the layout or finish of the premises 
or any part thereof, (ii) caused in whole or in part by Tenant through the 
delay of Tenant in submitting any plans and/or specifications, supplying 
information, approving plans, specifications or estimates, giving 
authorizations or otherwise or (iii) caused in whole or in part by delay 
and/or default on the part of Tenant or its contractors including, without 
limitation, the utility companies and other entities furnishing 
communications, data processing or other service or equipment. If the 
premises are deemed ready for Tenant's occupancy, pursuant to the foregoing, 
(and the term shall have commenced by reason thereof), but the premises are 
not in fact actually ready for Tenant's occupancy, Tenant shall not (except 
with Landlord's consent) be entitled to take possession of the premises for 
use as set forth in Exhibit 1 until the premises are in fact actually ready 
for such occupancy. Landlord's architect's certificate of substantial 
completion, as hereinabove stated, given in good faith, or of any other facts 
pertinent to this Article 4.2 shall be deemed conclusive of the statements 
therein contained and binding upon Tenant. Any of Landlord's work in the 
premises not fully completed on the Term Commencement Date shall thereafter 
be so completed with reasonable diligence by Landlord.

           (b)  Except for Landlord's Work, as hereinafter defined, the 
premises shall be taken "as-is" in its then (i.e., as of the Execution Date 
of this Lease) state of construction, finish, and decoration, without any 
obligation on the part of Landlord to construct or prepare the premises for 
Tenant's occupancy and without any representations and warranties by Landlord 
with respect to the condition of the Building and premises. Landlord shall 
construct the premises substantially in accordance with Space Plan SK-2, 
dated February 27, 1998, prepared by Interior Architects, Inc., and in 
accordance with Tenant's final approved plans, which plans shall be 
consistent with said Space Plan SK-2 ("Landlord's Work").

            (c)  Landlord shall contribute up to Ninety-Eight Thousand Five 
Hundred Fifty and 00/100 ($98,550.00) Dollars ("Landlords' Contribution") 
towards the cost of Landlord's Work. Tenant shall, within thirty (30) days of 
billing therefor, reimburse Landlord for all costs of Landlord's Work in 
excess of Landlord's Contribution. Tenant shall not be entitled to any unused 
portion of Landlord's Contribution.

     4.3   PLANS AND SPECIFICATIONS.  Tenant shall be solely responsible for 
the timely preparation and submission to Landlord of the final architectural, 
electrical and mechanical construction drawings, plans and specifications 
(called "plans") necessary to construct the premises for Tenant's occupancy, 
which plans shall be subject to approval by Landlord's architect and 
engineers and shall comply with their requirements to avoid aesthetic or 
other conflicts with the design and function of the balance of the Building. 
Landlord's approval is solely given for the benefit of Landlord and neither 
Tenant nor any third party shall have the right to reply upon Landlord's 
approval of Tenant's plans for any purpose whatsoever. Without limiting the 
foregoing, Tenant shall be responsible for all elements of the design of 
Tenant's plans (including, without limitation, compliance with law, 
functionality of design, the structural integrity of the design, the 
configuration of the premises and the placement of Tenant's furniture, 
appliances and equipment), and Landlord's approval of Tenant's plans shall in 
no event relieve Tenant of the responsibility for such design. If Tenant 
engages architects and engineers designated by Landlord to prepare Tenant's 
plans, then, notwithstanding anything to the contrary herein contained, 
Landlord shall pay for the

                                     -3-
<PAGE>

architectural and engineering fees incurred by Tenant in preparing Tenant's 
final approved plans, except that Landlord shall not be responsible for the 
cost of any changes made by Tenant after Landlord has approved Tenant's 
plans. Whether or not the layout and plans are prepared with the help (in 
whole or in part) of an architect or engineer designated by Landlord, Tenant 
agrees to remain solely responsible for the timely preparation and submission 
of all such plans and for all elements of the design of such plans and for 
all costs related thereto. Tenant has assured itself by direct communication 
with the architect and engineers (Landlord's or its own, as the case may be) 
that the final approved plans can be delivered to Landlord on or before the 
Final Plans Date as stated in Exhibit 1, provided that Tenant promptly 
furnishes complete information concerning its requirements to said architect 
and engineers as and when requested by them; and Tenant covenants and agrees 
to cause said final, approved plans and specifications to be delivered to 
Landlord on or before said Final Plans Date and to devote such time as may be 
necessary in consultation with said architect and engineers to enable them to 
complete and submit all plans within the required time limit. Time is of the 
essence in respect of preparation and submission of plans by Tenant. (The 
word "architect" as used in this Article 4 shall include an interior designer 
or space planner.)

     4.4   PREPARATION OF PREMISES.

           (a)  By Landlord. Except as is otherwise herein provided or as may 
be otherwise approved by the Landlord, all work necessary to prepare the 
premises for Tenant's occupancy, including work to be performed at Tenant's 
expense, shall be performed by contractors employed by Landlord.

           (b)  By Tenant. Subject always to the provisions of Articles 4.2 and 
4.3, if other than building standard categories of work are to be performed 
in preparing the premises for Tenant's occupancy by contractors other than 
those employed by Landlord, Landlord will give Tenant reasonable advance 
notice of the date on which the premises will be ready for such other 
contractors and a reasonable time will be allowed from such date for doing 
the work to be performed by such other contractors.

           (c)  If any work, including but not by way of limitation, 
installation of built-in equipment by the manufacturer or distributor 
thereof, shall be performed by contractors not employed by Landlord, Tenant 
shall take necessary reasonable measures to the end that such contractor 
shall cooperate in all ways with Landlord's contractors to avoid any delay to 
the work being performed by Landlord's contractors or conflict in any other 
way with the performance of such work.

     4.5   QUALITY AND COST OF MATERIALS.  Any construction or finish of the 
premises, whether by Landlord or Tenant, shall equal or exceed the 
specifications and quantities provided in Exhibit 3. Except for Landlord's 
Contribution, Tenant shall bear all costs of preparing the premises for its 
occupancy in accordance with the final plans.

     4.6   TENANT'S DELAY - ADDITIONAL COSTS.  If Tenant fails or omits 
to make timely submission to Landlord of the layout and plans referred to in 
Article 4.3, or other pertinent information, or delays in submitting any 
other plans or specifications, or in supplying information, or in approving 
plans, specifications or estimates, or in giving authorizations or fails to 
comply with Section 4.4(c) hereof, or otherwise fails to honor or perform its 
obligations under this Lease, any additional cost to Landlord in connection 
with the completion of the premises in accordance with the terms of this 
Lease and Exhibit 3 shall be promptly paid by Tenant to Landlord if such 
additional cost is in whole or in part the result of such failure, omission 
or delay of Tenant. For the purposes of the next preceding sentence, the 
expression "additional cost to Landlord" shall mean the cost over and above 
such cost as would have been the aggregate cost to Landlord of completing the 
premises in accordance with the terms of this Lease and Exhibit 3 had there 
been no such failure, omission or delay. Nothing contained in this Article 
4.6 shall limit or qualify or prejudice any other covenants, agreements, 
terms, provisions and conditions contained in this Lease, including, but 
not limited to Article 4.2.

                                       -4-
<PAGE>

     4.7   ENTRY BY TENANT PRIOR TO TERM COMMENCEMENT DATE.  With Landlord's 
prior written consent, which shall not be unreasonably withheld, Tenant 
shall have the right to enter the premises prior to the Term Commencement 
Date, during normal business hours and without payment of rent, to perform 
such work or decoration as is to be performed by, or under the direction or 
control of, Tenant and as is otherwise in compliance with the terms of this 
Lease. Such right of entry shall be deemed a license from Landlord to Tenant, 
and any entry thereunder shall be at the risk of Tenant.

     4.8   CONCLUSIVENESS OF LANDLORD'S PERFORMANCE.  Tenant shall be 
conclusively deemed to have agreed that Landlord has performed all of its 
obligations under this Article 4 unless not later than the end of the second 
calendar month next beginning after the Term Commencement Date Tenant shall 
give Landlord written notice specifying the respects in which Landlord has 
not performed any such obligation.

     4.9   TENANT PAYMENTS OF CONSTRUCTION COST.  Landlord shall have the 
same rights and remedies which Landlord has upon the nonpayment of Yearly 
Rent and other charges due under this Lease for nonpayment of any amounts 
which Tenant is required to pay to Landlord or Landlord's contractor in 
connection with the construction and initial preparation of the premises 
(including, without limitation, any amounts which Tenant is required to pay 
in accordance with Articles 4.5 and 4.6 hereof) or in connection with any 
construction in the premises performed for Tenant by Landlord, Landlord's 
contractor or any other person, firm or entity after the Term Commencement 
Date.

5.   USE OF PREMISES

     5.1   PERMITTED USE.  Tenant shall continuously during the term hereof 
occupy and use the premises only for the purposes as stated in Exhibit 1 and 
for no other purposes. Service and utility areas (whether or not a part of 
the premises) shall be used only for the particular purpose for which they 
were designed. Without limiting the generality of the foregoing, Tenant 
agrees that it shall not use the premises or any part thereof, or permit the 
premises or any part thereof to be used for the preparation or dispensing of 
food, whether by vending machines or otherwise. Notwithstanding the 
foregoing, but subject to the other terms and provisions of this Lease, 
Tenant may, with Landlord's prior written consent, which consent shall not be 
unreasonably withheld, install at its own cost and expense so-called hot-cold 
water fountains, coffee makers and so-called Dwyer refrigerator-sink-stove 
combinations for the preparation of beverages and foods, provided that no 
cooking, frying, etc., are carried on in the premises to such extent as 
requires special exhaust venting, Tenant hereby acknowledging that the 
Building is not engineered to provide any such special venting.

     5.2   PROHIBITED USES.  Notwithstanding any other provision of this 
Lease, Tenant shall not use, or suffer or permit the use or occupancy of, or 
suffer or permit anything to be done in or anything to be brought into or 
kept in or about the premises or the Building or any part thereof (including, 
without limitation, any materials appliances or equipment used in the 
construction or other preparation of the premises and furniture and 
carpeting): (i) which would violate any of the covenants, agreements, terms, 
provisions and conditions of this Lease or otherwise applicable to or binding 
upon the premises; (ii) for any unlawful purposes or in any unlawful manner; 
(iii) which, in the reasonable judgment of Landlord shall in any way (a) 
impair the appearance or reputation of the Building; or (b) impair, interfere 
with or otherwise diminish the quality of any of the Building services or the 
proper and economic heating, cleaning, ventilating, air conditioning or other 
servicing of the Building; or premises, or with the use or occupancy of any 
of the other areas of the Building, or occasion discomfort, inconvenience or 
annoyance, or injury or damage to any occupants of the premises or other 
tenants or occupants of the Building; or (iv) which is inconsistent with the 
maintenance of the Building as an office building of the first class in the 
quality of its maintenance, use, or occupancy. Tenant shall not install or 
use any electrical or other equipment of any kind which, in the reasonable 
judgment of Landlord, might cause any such impairment, interference, 
discomfort, inconvenience, annoyance or injury.

                                       -5-
<PAGE>

     5.3   LICENSES AND PERMITS.  If any governmental license or permit shall 
be required for the proper and lawful conduct of Tenant's business, and if 
the failure to secure such license or permit would in any way affect 
Landlord, the premises, the Building or Tenant's ability to perform any of 
its obligations under this Lease, Tenant, at Tenant's expense, shall duly 
procure and thereafter maintain such license and submit the same to 
inspection by Landlord. Tenant, at Tenant's expense, shall at all times 
comply with the terms and conditions of each such license or permit. Tenant 
shall furnish all data and information to governmental authorities and 
Landlord as required in accordance with legal, regulatory, licensing or other 
similar requirements as they relate to Tenant's use or occupancy of the 
premises or the Building.

6.   RENT

     During the term of this Lease the Yearly Rent and other charges, at the 
rate stated in Exhibit 1, shall be payable by Tenant to Landlord by monthly 
payments, as stated in Exhibit 1, in advance and without demand on the first 
day of each month for and in respect of such month. The rent and other 
charges reserved and covenanted to be paid under this Lease shall commence on 
the Term Commencement Date. Notwithstanding the provisions of the next 
preceding sentence, Tenant shall pay the first monthly installment of rent on 
the execution of this Lease. If, by reason of any provisions of this Lease, 
the rent reserved hereunder shall commence or terminate on any day other than 
the first day of a calendar month, the rent for such calendar month shall be 
prorated. The rent shall be payable to Landlord or, if Landlord shall so 
direct in writing, to Landlord's agent or nominee, in lawful money of the 
United States which shall be legal tender for payment of all debts and dues, 
public and private, at the time of payment, at the office of the Landlord or 
such place as Landlord may designate, and the rent and other charges in all 
circumstances shall be payable without any setoff or deduction whatsoever. 
Rental and any other sums due hereunder not paid within ten (10) days after 
the date due shall bear interest for each month or fraction thereof from the 
due date until paid computed at the annual rate of two percentage points over 
the so-called prime rate then currently from time to time charged to its most 
favored corporate customers by the largest national bank located in the city 
in which the Building is located, or at any applicable lesser maximum legally 
permissible rate for debts of this nature.

7.   RENTABLE AREA

     Total Rentable Area of the Premises and the Building shall be deemed to 
be as set forth in Exhibit 1.

8.   SERVICES FURNISHED BY LANDLORD

     8.1   ELECTRIC CURRENT.

           (a)  As stated in Exhibit 1, Landlord will furnish to Tenant, as 
an incident of this Lease, on a sub-metered basis, electric current for the 
operation of lighting fixtures, and the 120-volt electrical outlets initially 
installed in the premises for the operation of Tenant's normal office 
fixtures and equipment, but excluding any high energy consumption equipment, 
or Landlord will require Tenant to contract with the company supplying 
electric current for the purchase and obtaining by Tenant of electric current 
directly from such company to be billed directly to, and paid for by, Tenant.

           (b)  Tenant shall pay to Landlord, as additional rent, the cost of 
the electricity consumed on the premises during the term of this Lease as 
shown on such sub-meter based upon the Electric Rate. The parties acknowledge 
that the consumption of electricity in the premises (other than electricity 
consumed for the purposes of providing the services which Landlord is 
required to provide hereunder) will be measured by a separate sub-meter to be 
installed by Landlord. Tenant shall reimburse Landlord for the entire cost of 
such electric current as follows:

                                       -6-
<PAGE>

            1.  Commencing as of the Term Commencement Date and continuing 
                until the procedures set forth in Paragraph 2 of this Article
                8.1(b) are effected, Tenant shall pay to Landlord at the same
                time and in the same manner that it pays its monthly payments
                of Yearly Rent hereunder, estimated monthly payments on 
                account of Tenant's obligation to reimburse Landlord for 
                electricity consumed in the premises. Said estimated monthly 
                payments are based upon the Base Electric Cost and Electric
                Rate set forth on Exhibit 1. The Initial Estimated Monthly
                Electric Payment is set forth on Exhibit 1.

            2.  Periodically after the Term Commencement Date, Landlord shall 
                determine the actual cost of electricity consumed by Tenant in
                the premises (i.e. by reading Tenant's sub-meter and by 
                applying the actual Electric Rate(s) applicable to the
                preceding period). If the total of Tenant's estimated monthly
                payments on account of such period is less than the actual 
                cost of electricity consumed in the premises during such 
                period, Tenant shall pay the difference to Landlord when billed
                therefor. If the total of Tenant's estimated monthly payments
                on account of such period is greater than the actual cost of
                electricity consumed in the premises during such period, Tenant
                may credit the difference against its next installment of 
                rental or other charges due hereunder.

            3.  After each adjustment, as set forth in Paragraph 2 above, the
                amount of estimated monthly payments on account of Tenant's 
                obligation to reimburse Landlord for electricity in the 
                premises shall be adjusted based upon the actual cost of 
                electricity consumed during the immediately preceding period.

           (c)  If Landlord shall require Tenant to contract with the company 
supplying electric current for the purchase and obtaining by Tenant of 
electric current directly from such company, either initially or pursuant to 
Landlord's option as set forth in Subparagraph 8.1(d) below, Tenant shall 
contract with such company and shall pay all charges for such electric 
current directly to such company promptly when due.

           (d)  If Landlord is furnishing Tenant electric current hereunder 
either on an additional rent basis or a sub-metered basis, Landlord, at any 
time, at its option and upon not less than thirty (30) days' prior written 
notice to Tenant, may discontinue such furnishing of electric current to the 
premises; and in such case Tenant shall contract with the company supplying 
electric current for the purchase and obtaining by Tenant of electric current 
directly from such company. In the event Tenant itself contracts for 
electricity with the supplier, either initially or pursuant to Landlord's 
option as above stated, Landlord shall (i) permit its risers, conduits and 
feeders to the extent available, suitable and safely capable, to be used for 
the purpose of enabling Tenant to purchase and obtain electric current 
directly from such company, (ii) without cost or charge to Tenant, make such 
alterations and additions to the electrical equipment and/or appliances in 
the Building as such company shall specify for the purpose of enabling Tenant 
to purchase and obtain electric current directly from such company, and (iii) 
at Landlord's expense, furnish and install in or near the premises any 
necessary metering equipment used in connection with measuring Tenant's 
consumption of electric current and Tenant, at Tenant's expense, shall 
maintain and keep in repair such metering equipment. In the event that 
Landlord shall exercise the option set forth in this Subparagraph 8.1(d), 
then (i) if Landlord is furnishing Tenant electric current on an additional 
rent basis, Tenant shall have no further obligation to pay Electricity Rent 
to Landlord after the date Landlord discontinues such furnishing of electric 
current or (ii) if Landlord is furnishing Tenant electric current on a 
sub-metered basis, Tenant shall have no further obligation to make any 
Estimated Monthly Electric Payments after the date Landlord discontinues such 
furnishing of electric current.

                                       -7-
<PAGE>

           (e)   Whether or not Landlord is furnishing electric current to 
Tenant, if Tenant shall require electric current for use in the premises in 
excess of such reasonable quantity to be furnished for such use as 
hereinabove provided and if (i) in Landlord's reasonable judgment, Landlord's 
facilities are inadequate for such excess requirements or (ii) such excess 
use shall result in an additional burden on the Building air conditioning 
system and additional cost to Landlord on account thereof then, as the case 
may be, (x) Landlord upon written request and at the sole cost and expense of 
Tenant, will furnish and install such additional wire, conduits, feeders, 
switchboards and appurtenances as reasonably may be required to supply such 
additional requirements of Tenant if current therefor be available to 
Landlord, provided that the same shall be permitted by applicable laws and 
insurance regulations and shall not cause damage to the Building or the 
premises or cause or create a dangerous or hazardous condition or entail 
excessive or unreasonable alterations or repairs or interfere with or disturb 
other tenants or occupants of the Building or (y) Tenant shall reimburse 
Landlord for such additional cost, as aforesaid.

           (f)   Landlord, upon Tenant's request, shall purchase and install 
all replacement lamps of types generally commercially available (including, 
but not limited to, incandescent and fluorescent) used in the premises.

           (g)   Landlord shall not in any way be liable or responsible to 
Tenant for any loss, damage or expense which Tenant may sustain or incur if 
the quantity, character, or supply of electrical energy is changed or is no 
longer available or suitable for Tenant's requirements.

           (h)   Tenant agrees that it will not make any material alteration 
or material addition to the electrical equipment and/or appliances in the 
premises without the prior written consent of Landlord in each instance first 
obtained, which consent will not be unreasonably withheld, and will promptly 
advise Landlord of any other alteration or addition to such electrical 
equipment and/or appliances.

    8.2    WATER. Landlord shall furnish hot and cold water for ordinary 
premises, cleaning, toilet, lavatory and drinking purposes. If Tenant 
requires, uses or consumes water for any purpose other than for the 
aforementioned purposes, Landlord may (i) assess a reasonable charge for the 
additional water so used or consumed by Tenant or (ii) install a water meter 
and thereby measure Tenant's water consumption for all purposes. In the 
latter event, Landlord shall pay the cost of the meter and the cost of 
installation thereof and shall keep said meter and installation equipment in 
good working order and repair. Tenant agrees to pay for water consumed, as 
shown on said meter, together with the sewer charge based on said meter 
charges, as and when bills are rendered, and on default in making such 
payment Landlord may pay such charges and collect the same from Tenant. All 
piping and other equipment and facilities for use of water outside the 
building core will be installed and maintained by Landlord at Tenant's sole 
cost and expense.

    8.3    ELEVATORS, HEAT, CLEANING.

           (a)   Landlord at its expense shall: (i) provide necessary 
elevator facilities (which may be manually or automatically operated, either 
or both, as Landlord may from time to time elect) on Mondays through Fridays, 
excepting legal holidays, from 8:00 a.m. to 6:00 p.m. and on Saturdays, 
excepting legal holidays, from 8:00 a.m. to 1:00 p.m. (called "business 
days") and have one elevator in operation available for Tenant's use, 
non-exclusively, together with others having business in the Building, at all 
other times; (ii) furnish heat (substantially equivalent to that being 
furnished in comparably aged similarly equipped office buildings in the same 
city) to the premises during the normal heating season on business days; and 
(iii) cause the office areas of the premises to be cleaned on business days 
(except on Saturdays) provided the same are kept in order by Tenant. Either 
Exhibit 4 (if annexed hereto) or, otherwise, the cleaning standards generally 
prevailing in first-class office buildings in the city or town where the 
Building is located, shall represent substantially the extent and scope of 
the cleaning by Landlord referred to in this Article 8.3.

                                      -8-


<PAGE>

           (b)   The parties agree and acknowledge that, despite reasonable 
precautions in selecting cleaning and maintenance contractors and personnel, 
any property or equipment in the premises of a delicate, fragile or 
vulnerable nature may nevertheless be damaged in the course of cleaning and 
maintenance services being performed. Accordingly, Tenant shall take 
reasonable protective precautions with such property and equipment 
(including, without limitation, computers or other data processing components 
or equipment and optical or electronic equipment, etc.), e.g., housing the 
property and equipment in a separate, locked room, so as to render it 
inaccessible to the Building's cleaning personnel.

    8.4    AIR CONDITIONING. Landlord shall through the air conditioning 
equipment of the Building furnish to and distribute in the premises air 
conditioning as normal seasonal changes may require on business days during 
the hours as aforesaid in Article 8.3 when air conditioning may reasonably be 
required for the comfortable occupancy of the premises by Tenant. Tenant 
agrees to lower and close the blinds or drapes when necessary because of the 
sun's position, whenever the air conditioning system is in operation, and to 
cooperate fully with Landlord with regard to, and to abide by all the 
reasonable regulations and requirements which Landlord may prescribe for the 
proper functioning and protection of the air conditioning system. The air 
conditioning system referred to in this Article 8.4 shall be capable of 
providing 78DEG. F dry bulb and 50% relative humidity with outside conditions 
of 92DEG. F dry bulb and 74DEG. F wet bulb. The foregoing design conditions 
shall be based upon an occupancy within each separately partitioned area in 
the premises of not more than one person per 100 square feet of Total 
Rentable Area and upon a combined lighting and standard electrical load not 
to exceed 2 1/2 watts per square foot of Total Rentable Area.

    8.5    ADDITIONAL HEAT, CLEANING AND AIR CONDITIONING SERVICES.

           (a)   Landlord will use reasonable efforts upon reasonable advance 
written notice from Tenant of its requirements in that regard, to furnish 
additional heat, cleaning or air conditioning services to the premises on 
days and at times other than as above provided.

           (b)   Tenant will pay to Landlord a reasonable charge (i) for any 
such additional heat, cleaning or air conditioning service required by 
Tenant, (ii) for any extra cleaning of the premises required because of the 
carelessness or indifference of Tenant or because of the nature of Tenant's 
business, and (iii) for any cleaning done at the request of Tenant of any 
portions of the premises which may be used for storage, shipping room or 
other non-office purposes. If the cost to Landlord for cleaning the premises 
shall be increased due to the installation in the premises, at Tenant's 
request, of any materials or finish other than those which are building 
standard, Tenant shall pay to Landlord an amount equal to such increase in 
cost.

    8.6    ADDITIONAL AIR CONDITIONING EQUIPMENT. In the event Tenant 
requires additional air conditioning for business machines, meeting rooms or 
other special purposes, or because of occupancy or excess electrical loads, 
any additional air conditioning units, chillers, condensers, compressors, 
ducts, piping and other equipment, such additional air conditioning equipment 
will be installed and maintained by Landlord at Tenant's sole cost and 
expense, but only if, in Landlord's reasonable judgment, the same will not 
cause damage or injury to the Building or create a dangerous or hazardous 
condition or entail excessive or unreasonable alterations, repairs or expense 
or interfere with or disturb other tenants; and Tenant shall reimburse 
Landlord in such an amount as will compensate it for the cost incurred by it 
in operating such additional air conditioning equipment.

    8.7    REPAIRS. Except as otherwise provided in Articles 18 and 20, and 
subject to Tenant's obligations in Article 14, Landlord shall keep and 
maintain the roof, exterior walls, structural floor slabs, columns, 
elevators, public stairways and corridors, lavatories, equipment (including, 
without limitation, sanitary, electrical, heating, air conditioning, or other 
systems) and other common facilities of the Building in good condition and 
repair.

    8.8    INTERRUPTION OR CURTAILMENT OF SERVICES. When necessary by reason 
of accident or emergency, or for repairs, alterations, replacements or 
improvements which in the reasonable judgment of Landlord are desirable or 
necessary to be made, or of difficulty or inability in securing supplies or 
labor, or of strikes, or of any other cause beyond the control of Landlord, 
whether such other cause be similar or dissimilar to those hereinabove 
specifically mentioned until said cause has been removed, Landlord reserves 
the right to interrupt, curtail, stop or suspend (i) the furnishing of 
heating, elevator, air conditioning, and cleaning services and (ii) the 
operation of the plumbing and electric systems. Landlord shall exercise 
reasonable diligence to eliminate the cause of any such interruption, 
curtailment, stoppage or suspension, but there shall be no diminution or 
abatement of rent or other compensation due from Landlord to Tenant 
hereunder, nor shall this Lease be affected or any of the Tenant's 
obligations hereunder reduced, and the Landlord shall have no responsibility 
or liability for any such interruption, curtailment, stoppage, or suspension 
of services or systems.

    8.9    ENERGY CONSERVATION. Notwithstanding anything to the contrary in 
this Article 8 or in this Lease contained, Landlord may institute, and 
Tenant shall comply with, such policies, programs and measures as may be 
necessary, required, or expedient for the conservation and/or preservation of 
energy or energy services, or as may be necessary or required to comply with 
applicable codes, rules regulations or standards.

    8.10   MISCELLANEOUS. Other than air conditioning, all services provided 
by Landlord to Tenant are based upon an assumed maximum premises population 
of one person per two hundred (200) square feet of Total Rentable Area, which 
limit Tenant shall in no event exceed.

                                      -10-


<PAGE>

           (e)   "Tax Base" shall be the amount stated in Exhibit 1 and shall 
apply to a Tax Period of twelve (12) months. Tax Base shall be reduced pro

           (f)   "Tax Period" shall be any fiscal/tax period in respect of 
which Taxes are due and payable to the appropriate governmental taxing 
authority, any portion of which period occurs during the term of this Lease, 
the first such Period being the one in which the Term Commencement Date

           (g)   "Operating Costs":

                 (1)   Definition of Operating Costs. "Operating Costs" shall 
           mean all costs incurred and expenditures of whatever nature made 
           by Landlord in the operation and management, for repair and 
           replacements, cleaning and maintenance of the Building and grounds 
           including, without limitation, vehicular and pedestrian 
           passageways related to the Building (but excluding those areas, if 
           any, outside the Building and for which operating expenses are 
           chargeable to non-office (i.e., commercial) tenants), related 
           equipment, facilities and appurtenances, elevators, cooling and 
           heating equipment. In the event that Landlord or Landlord's 
           managers or agents perform services for the benefit of the 
           Building off-site which would otherwise be performed on-site 
           (e.g., accounting), the cost of such services shall be reasonably 
           allocated among the properties benefiting from such service and 
           shall be included in Operating Costs. The Building's pro rata 
           share (as reasonably determined by Landlord) of the cost of 
           operating, managing (including, without limitation, the cost of 
           the management office for the buildings and facilities and the 
           Park), maintaining and cleaning (including, without limitation, 
           snow and ice removal) the parking and other common areas and 
           facilities of the Park shared by the Building and other buildings 
           in the Park shall be included in Operating Costs. Operating Costs 
           shall include, without limitation, those categories of 
           "Specifically Included Operating Costs," as set forth below, but 
           shall not include "Excluded Costs," as hereinafter defined.

                 (2)   Definition of Excluded Costs. "Excluded Costs" shall 
           be defined as mortgage charges, brokerage commissions, salaries of 
           executives and owners not directly employed in the 
           management/operation of the Building, the cost of work done by 
           Landlord for a particular tenant for which Landlord has the right 
           to be reimbursed by such Tenant, and, subject to Subparagraph (3) 
           below, such portion of expenditures as are not properly chargeable 
           against income.

                 (3)   Capital Expenditures.

                       (i)   REPLACEMENTS. If, during the term of this Lease, 
                 Landlord shall replace any capital items or make any capital 
                 expenditures (collectively called "capital expenditures") 
                 the total amount of which is not properly includible in 
                 Operating Costs for the Operating Year in which they were 
                 made, there shall nevertheless be included in such Operating 
                 Costs and in Operating Costs for each succeeding Operating 
                 Year the amount, if any, by which the Annual Charge-Off 
                 (determined as hereinafter provided) of such capital 
                 expenditure (less insurance proceeds, if any, collected by 
                 Landlord by reason of damage to, or destruction of the 
                 capital item being replace) exceeds the annual Charge-Off of 
                 the capital expenditure for the item being replaced.

                       (ii)  NEW CAPITAL ITEMS. If a new capital item is 
                 acquired which does not replace another capital item which 
                 was worn out, has become obsolete, etc., then there shall be 
                 included in Operating Costs for each Operating Year in

                                      -11-


<PAGE>

                 which and after such capital expenditure is made the Annual 
                 Charge-Off of such capital expenditure.

                       (iii) ANNUAL CHARGE-OFF. "Annual Charge-Off" shall be 
                 defined as the annual amount of principal and interest 
                 payments which would be required to repay a loan ("Capital 
                 Loan") in equal monthly installments over the Useful Life, 
                 as hereinafter defined, of the capital item in question on a 
                 direct reduction basis at an annual interest rate equal to 
                 the Capital Interest Rate, as hereinafter defined, where the 
                 initial principal balance is the cost of the capital item in 
                 question. Notwithstanding the foregoing, if Landlord 
                 reasonably concludes on the basis of engineering estimates 
                 that a particular capital expenditure will effect savings in 
                 Building operating expenses including, without limitation, 
                 energy-related costs, and that such projected savings will, 
                 on an annual basis ("Projected Annual Savings"), exceed the 
                 Annual Charge-Off of such capital expenditure computed as 
                 aforesaid, then and in such events, the Annual Charge-Off 
                 shall be increased to an amount equal to the Projected 
                 Annual Savings; and in such circumstances, the increased 
                 Annual Charge-Off (in the amount of the Projected Annual 
                 Savings) shall be made for such period of time as it would 
                 take to fully amortize the cost of the capital item in 
                 question, together with interest thereon at the Capital 
                 Interest Rate as aforesaid, in equal monthly payments, each 
                 in the amount of one-twelfth (1/12th) of the Projected 
                 Annual Savings, with such payments being applied first to 
                 interest and the balance to principal.

                       (iv)  USEFUL LIFE. "Useful Life" shall be reasonably 
                 determined by Landlord in accordance with generally accepted 
                 accounting principles and practices in effect at the time of 
                 acquisition of the capital item.

                       (v)   CAPITAL INTEREST RATE. "Capital Interest Rate" 
                 shall be defined as an annual rate of either one percentage 
                 point over the AA Bond rate (Standard & Poor's corporate 
                 composite or, if unavailable, its equivalent) as reported in 
                 the financial press at the time the capital expenditure is 
                 made or, if the capital item is acquired through third-party 
                 financing, then the actual (including fluctuating) rate paid 
                 by Landlord in financing the acquisition of such capital 
                 item.

                 (4)   Specifically Included Categories of Operating Costs. 
           Operating Costs shall include, but not be limited to, the 
           following:

                       Taxes (other than real estate taxes): Sales, Federal 
           Social Security, Unemployment and Old Age Taxes and contributions 
           and State Unemployment taxes and contributions accruing to and 
           paid by the Landlord on account of all employees of Landlord 
           and/or Landlord's managing agent, who are employed in, about or 
           on account of the Building, except that taxes levied upon the net 
           income of the Landlord and taxes withheld from employees, and 
           "Taxes" as defined in Article 9.1(d) shall not be included herein.

                       Water: All charges and rates connected with water 
           supplied to the Building and related sewer use charges.

                       Heat and Air Conditioning: All charges connected with 
           heat and air conditioning supplied to the Building.

                                      -12-


<PAGE>

                       Wages: Wages and cost of all employee benefits of all 
           employees of the Landlord and/or Landlord's managing agent who 
           are employed in, about or on account of the Building. 

                       Cleaning: The cost of labor and material for cleaning 
           the Building, surrounding areaways and windows in the Building.

                       Elevator Maintenance: All expenses for or on account 
           of the upkeep and maintenance of all elevators in the Building.

                       Electricity: The cost of all electric current for the 
           operation of any machine, appliance or device used for the 
           operation of the premises and the Building, including the cost of 
           electric current for the elevators, lights, air conditioning and 
           heating, but not including electric current which is paid for 
           directly to the utility by the user/tenant in the Building. (If 
           and so long as Tenant is billed directly by the electric utility 
           for its own consumption as determined by its separate meter, then 
           Operating Costs shall include only Building and public area 
           electric current consumption and not any demised premises electric 
           current consumption. Wherever separate metering is unlawful, 
           prohibited by utility company regulation or tariff or is otherwise 
           impracticable, relevant consumption figures for the purposes of 
           this Article 9 shall be determined by fair and reasonable 
           allocations and engineering estimates made by Landlord. 
           Furthermore, if and to the extent that the 
           Operating-Costs-in-the-Base-Year figure shall include any 
           component representing the cost to the Landlord of electric 
           current supplied to any tenant's premises under so-called 
           "rent-inclusion" lease arrangements, then if such cost is 
           eliminated from Operating Costs in an Operating Year in 
           accordance with the foregoing provisions, the figure for 
           Operating Costs in the Base Year for the purposes of this Article 
           9 shall likewise be reduced by the amount for such cost 
           component.)

                       Insurance, etc.: Fire, casualty, liability and such 
           other insurance as may from time to time be required by lending 
           institutions on first-class office buildings in the City or Town 
           wherein the Building is located and all other expenses 
           customarily incurred in connection with the operation and 
           maintenance of first-class office buildings in the City or Town 
           wherein the Building is located including, without limitation, a 
           management fee payable by Landlord and rental costs associated 
           with the Park's management office.
           
           9.2    TAX EXCESS. If in any Tax Period the Taxes exceed the Tax 
Base, Tenant shall pay to Landlord Tenant's Proportionate Share of such 
excess, such amount being hereinafter referred to as "Tax Excess." Tax Excess 
shall be due when billed by Landlord. In implementation and not in limitation 
of the foregoing, Tenant shall remit to Landlord pro rata monthly 
installments on account of projected Tax Excess, calculated by Landlord on 
the basis of the most recent Tax data available. If the total of such monthly 
remittances on account of any Tax Period is greater than the actual Tax 
Excess for such Tax Period, Tenant may credit the difference against the next 
installment of rental or other charges due to Landlord hereunder. If the 
total of such remittances is less than the actual Tax Excess for such Tax 
Period, Tenant shall pay the difference to Landlord when billed therefor.

           Appropriate credit against Tax Excess shall be given for any 
refund obtained by reason of a reduction in any Taxes by the Assessors or the 
administrative, judicial or other governmental agency responsible therefor. 
The original computations, as well as reimbursement or payments of additional 
charges, if any, or allowances, if any, under the provisions of this Article 
9.2 shall be based on the original assessed valuations with adjustments to be 
made at a later date when the tax refund, if any, shall be paid to

                                    -13-
<PAGE>

Landlord by the taxing authorities. Expenditures for legal fees and for other 
similar or dissimilar expenses incurred in obtaining the tax refund may be 
charged against the tax refund before the adjustments are made for the Tax 
Period. 

    9.3    OPERATING EXPENSE EXCESS. If the Operating Costs in any Operating 
Year exceed the Operating Costs in the Base Year, Tenant shall pay to 
Landlord Tenant's Proportionate Share of such excess, such amount being 
hereinafter referred to as "Operating Expense Excess." Operating Expense 
Excess shall be due when billed by Landlord. In implementation and not in 
limitation of the foregoing, Tenant shall remit to Landlord pro rata monthly 
installments on account of projected Operating Expense Excess, calculated by 
Landlord on the basis of the most recent Operating Costs data or budget 
available. If the total of such monthly remittances on account of any 
Operating Year is greater than the actual Operating Expense Excess for such 
Operating Year, Tenant may credit the difference against the next installment 
of rent or other charges due to Landlord hereunder. If the total of such 
remittances is less than actual Operating Expense Excess for such Operating 
Year, Tenant shall pay the difference to Landlord when billed therefor.

    9.4    PART YEARS. If the Term Commencement Date or the Termination Date 
occurs in the middle of an Operating Year or Tax Period, Tenant shall be 
liable for only that portion of the Operating Expense or Tax Excess, as the 
case may be, in respect of such Operating Year or Tax Period represented by a 
fraction the numerator of which is the number of days of the herein term 
which falls within the Operating Year or Tax Period and the denominator of 
which is three hundred sixty-five (365), or the number of days in said Tax 
Period, as the case may be.

    9.5    EFFECT OF TAKING. In the event of any taking of the Building or 
the land upon which it stands under circumstances whereby this Lease shall 
not terminate under the provisions of Article 20 then, for the purposes of 
determining Tax Excess, there shall be substituted for the Tax Base 
originally provided for herein a fraction of such Tax Base, the numerator of 
which fraction shall be the Taxes for the first Tax Period subsequent to the 
condemnation or taking which takes into account such condemnation or taking, 
and the denominator of which shall be the Taxes for the last Tax Period prior 
to the condemnation or taking, which did not take into account such 
condemnation or taking. Tenant's Proportionate Share shall be adjusted 
appropriately to reflect the proportion of the premises and/or the Building 
remaining after such taking.

    9.6    DISPUTES, ETC. Any disputes arising under this Article 9 may, at 
the election of either party, be submitted to arbitration as hereinafter 
provided. Any obligations under this Article 9 which shall not have been paid 
at the expiration or sooner termination of the term of this Lease shall 
survive such expiration and shall be paid when and as the amount of same 
shall be determined to be due.

10. CHANGES OR ALTERATIONS BY LANDLORD

    Landlord reserves the right, exercisable by itself or its nominee, at any 
time and from time to time without the same constituting an actual or 
constructive eviction and without incurring any liability to Tenant therefor 
or otherwise affecting Tenant's obligations under this Lease, to make such 
changes, alterations, additions, improvements, repairs or replacements in or 
to (i) the Building (including the premises) and the fixtures and equipment 
thereof, (ii) the street entrances, halls, passages, elevators, escalators, 
and stairways of the Building, as it may deem necessary or desirable, and 
(iii) the arrangement and/or location of entrances or passageways, doors and 
doorways, and corridors, elevators, stairs, toilets, or other public parts of 
the Building, or (iv) the parking and other common areas of the Park, 
provided, however, that there be no unreasonable obstruction of the right of 
access to, or unreasonable interference with the use and enjoyment of, the 
premises by Tenant. Nothing contained in this Article 10 shall be deemed to 
relieve Tenant of any duty, obligation or liability of Tenant with respect to 
making any repair, replacement or improvement or complying with any law, 
order or requirement of any governmental or

                                    -14-
<PAGE>

other authority. Landlord reserves the right to adopt and at any time and 
from time to time to change the name or address of the Building. Neither this 
Lease nor any use by Tenant shall give Tenant any right or easement for the 
use of any door or any passage or any concourse connecting with any other 
building or to any public convenience, and the use of such doors, passages and 
concourses and of such conveniences may be regulated or discontinued at any 
time and from time to time by Landlord without notice to Tenant and without 
affecting the obligation of Tenant hereunder or incurring any liability to 
Tenant therefor, provided, however, that there be no unreasonable obstruction 
of the right of access to, or unreasonable interference with the use of the 
premises by Tenant.

    If at any time any windows of the premises are temporarily closed or 
darkened for any reason whatsoever including but not limited to, Landlord's 
own acts, Landlord shall not be liable for any damage Tenant may sustain 
thereby and Tenant shall not be entitled to any compensation therefor nor
abatements of rent nor shall the same release Tenant from its obligations 
hereunder nor constitute an eviction.

11. FIXTURES, EQUIPMENT AND IMPROVEMENTS--REMOVAL BY TENANT

    All fixtures, equipment, improvements and appurtenances attached to or 
built into the premises prior to or during the term, whether by Landlord at 
its expense or at the expense of Tenant (either or both) or by Tenant shall 
be and remain part of the premises and shall not be removed by Tenant during 
or at the end of the term unless Landlord otherwise elects to require Tenant 
to remove such fixtures, equipment, improvements and appurtenances, in 
accordance with Articles 12 and/or 22 of the Lease. All electric, telephone, 
telegraph, communication, radio, plumbing, heating and sprinkling systems, 
fixtures and outlets, vaults, paneling, molding, shelving, radiator 
enclosures, cork, rubber, linoleum and composition floors, ventilating, 
silencing, air conditioning and cooling equipment, shall be deemed to be 
included in such fixtures, equipment, improvements and appurtenances, whether 
or not attached to or built into the premises. Where not built into the 
premises, all removable electric fixtures, carpets, drinking or tap water 
facilities, furniture, or trade fixtures or business equipment or Tenant's 
inventory or stock in trade shall not be deemed to be included in such 
fixtures, equipment, improvements and appurtenances and may be, and upon the 
request of Landlord will be, removed by Tenant upon the condition that such 
removal shall not materially damage the premises or the Building and that the 
cost of repairing any damage to the premises or the Building arising from 
installation or such removal shall be paid by Tenant. If this Lease shall be 
terminated by reason of Tenant's breach or default, then, notwithstanding 
anything to the contrary in this Lease contained, Landlord shall have a lien 
against all Tenant's property in the premises or elsewhere in the Building at 
the time of such termination to secure Landlord's rights under Article 21 
hereof. Tenant shall, within ten (10) days of Landlord's written request, 
from time to time, execute and deliver to Landlord such documentation (e.g., 
UCC statements) as may be necessary to enable Landlord to perfect such lien.

12. ALTERATION AND IMPROVEMENTS BY TENANT

    Tenant shall make no alterations, decorations, installations, removals, 
additions or improvements in or to the premises without Landlord's prior 
written consent and then only those (i) which equal or exceed the 
specifications and quantities provided in Exhibit 3, and (ii) made by 
contractors or mechanics approved by Landlord. No installations or work shall 
be undertaken or begun by Tenant until: (i) Landlord has approved written 
plans and specifications and a time schedule for such work; (ii) Tenant has 
made provision for either written waivers of liens from all contractors, 
laborers and suppliers of materials for such installations or work, the filing 
of lien bonds on behalf of such contractors, laborers and suppliers, or other 
appropriate protective measures approved by Landlord; and (iii) Tenant has 
procured appropriate surety payment and performance bonds. No amendments or 
additions to such plans and specifications shall be made without the prior 
written consent of Landlord. Landlord's consent and approval required under 
this Article 12 shall not be unreasonably withheld. Landlord's approval is 
solely given for the benefit of Landlord and neither Tenant nor any third 
party shall have the right to rely upon Landlord's approval of Tenant's plans 
for any purpose whatsoever. Without limiting the foregoing, Tenant shall be

                                    -15-
<PAGE>

responsible for all elements of the design of Tenant's plans (including, 
without limitation, compliance with law, functionality of design, the 
structural integrity of the design, the configuration of the premises and the 
placement of Tenant's furniture, appliances and equipment), and Landlord's 
approval of Tenant's plans shall in no event relieve Tenant of the 
responsibility for such design. Landlord shall have no liability or 
responsibility for any claim, injury or damage alleged to have been caused by 
the particular materials, whether building standard or non-building standard, 
appliances or equipment selected by Tenant in connection with any work 
performed by or on behalf of Tenant in the premises including, without 
limitation, furniture, carpeting, copiers, laser printers, computers and 
refrigerators. Any such work, alterations, decorations, installations, 
removals, additions and improvements shall be done at Tenant's sole expense 
and at such times and in such manner as Landlord may from time to time 
designate. If Tenant shall make any alterations, decorations, installations, 
removals, additions or improvements then Landlord may elect to require the 
Tenant at the expiration or sooner termination of the term of this Lease to 
restore the premises to substantially the same condition as existed at the 
Term Commencement Date. Tenant shall pay, as an additional charge, the entire 
increase in real estate taxes on the Building which shall, at any time prior 
to or after the Term Commencement Date, result from or be attributable to 
any alteration, addition or improvement to the premises made by or for the 
account of Tenant in excess of the specifications and quantities provided in 
Exhibit 3.

13. TENANT'S CONTRACTORS--MECHANICS' AND OTHER LIENS--STANDARD OF TENANT'S    
    PERFORMANCE--COMPLIANCE WITH LAWS

    Whenever Tenant shall make any alterations, decorations, installations, 
removals, additions or improvements in or to the premises--whether such work 
be done prior to or after the Term Commencement Date--Tenant will strictly 
observe the following covenants and agreements:

           (a)   Tenant agrees that it will not, either directly or 
indirectly, use any contractors and/or materials if their use will create any 
difficulty, whether in the nature of a labor dispute or otherwise, with other 
contractors and/or labor engaged by Tenant or Landlord or others in the 
construction, maintenance and/or operation of the Building or any part 
thereof.

           (b)   In no event shall any material or equipment be incorporated 
in or added to the premises, so as to become a fixture or otherwise a part of 
the Building, in connection with any such alteration, decoration, 
installation, addition or improvement which is subject to any lien, charge, 
mortgage or other encumbrance of any kind whatsoever or is subject to any 
security interest or any form of title retention agreement. No installations 
or work shall be undertaken or begun by Tenant until (i) Tenant has made 
provision for written waiver of liens from all contractors, laborers and 
suppliers of materials for such installations or work, and taken other 
appropriate protective measures approved by Landlord; and (ii) Tenant has 
procured appropriate surety payment and performance bonds which shall name 
Landlord as an additional obligee and has filed lien bonds(s) (in 
jurisdictions where available) on behalf of such contractors, laborers and 
suppliers. Any mechanic's lien filed against the premises or the Building for 
work claimed to have been done for, or materials claimed to have been 
furnished to, Tenant shall be discharged by Tenant within ten (10) days 
thereafter, at Tenant's expense by filing the bond required by law or 
otherwise. If Tenant fails so to discharge any lien, Landlord may do so at 
Tenant's expense and Tenant shall reimburse Landlord for any expense or cost 
incurred by Landlord in so doing with fifteen (15) days after rendition of a 
bill therefor.

           (c)   All installations or work done by Tenant shall be at its own 
expense and shall at all times comply with (i) laws, rules, orders and 
regulations of governmental authorities having jurisdiction thereof; (ii) 
orders, rules and regulations of any Board of Fire Underwriters, or any other 
body hereafter constituted exercising similar functions, and governing 
insurance rating bureaus; (iii) Rules and Regulations of Landlord; and (iv) 
plans and specifications prepared by and at the expense of Tenant theretofore 
submitted to and approved by Landlord.

                                    -16-

<PAGE>

           (d)   Tenant shall procure all necessary permits before 
undertaking any work in the premises; do all of such work in a good and 
workmanlike manner, employing materials of good quality and complying with 
all governmental requirements; and defend, save harmless, exonerate and 
indemnify Landlord from all injury, loss or damage to any person or property 
occasioned by or growing out of such work. Tenant shall cause contractors 
employed by Tenant to carry Worker's Compensation Insurance in accordance 
with statutory requirements, Automobile Liability Insurance and, naming 
Landlord as an additional insured, Commercial General Liability Insurance 
covering such contractors on or about the premises in the amounts stated in 
Article 15 hereof or in such other reasonable amounts as Landlord shall 
require and to submit certificates evidencing such coverage to Landlord prior 
to the commencement of such work.

14. REPAIRS BY TENANT--FLOOR LOAD

    14.1   REPAIRS BY TENANT. Tenant shall keep all and singular the premises 
neat and clean (including periodic rug shampoo and waxing of tiled floors and 
cleaning of blinds and drapes) and in such repair, order and condition as the 
same are in on the Term Commencement Date or may be put in during the term 
hereof, reasonable use and wearing thereof and damage by fire or by other 
casualty excepted. Tenant shall be solely responsible for the proper 
maintenance of all equipment and appliances operated by Tenant, including, 
without limitation, copiers, laser printers, computers and refrigerators. 
Tenant shall make, as and when needed as a result of misuse by, or neglect or 
improper conduct of, Tenant or Tenant's servants, employees, agents, 
contractors, invitees, or licensees or otherwise, all repairs in and about 
the premises necessary to preserve them in such repair, order and condition, 
which repairs shall be in quality and class equal to the original work. 
Landlord may elect, at the expense of Tenant, to make any such repairs or to 
repair any damage or injury to the Building or the premises caused by moving 
property of Tenant in or out of the Building, or by installation or removal 
of furniture or other property, or by misuse by, or neglect, or improper 
conduct of, Tenant or Tenant's servants, employees, agents, contractors, or 
licensees.

    14.2   FLOOR LOAD--HEAVY MACHINERY. Tenant shall not place a load upon 
any floor of the premises exceeding the floor load per square foot of area 
which such floor was designed to carry and which is allowed by law. Landlord 
reserves the right to prescribe the weight and position of all business 
machines and mechanical equipment, including safes, which shall be placed so 
as to distribute the weight. Business machines and mechanical equipment shall 
be placed and maintained by Tenant at Tenant's expense in settings sufficient 
in Landlord's judgment to absorb and prevent vibration, noise and annoyance. 
Tenant shall not move any safe, heavy machinery, heavy equipment, freight, 
bulky matter, or fixtures into or out of the Building without Landlord's 
prior written consent. If such safe, machinery, equipment, freight, bulky 
matter or fixtures requires special handling, Tenant agrees to employ only 
persons holding a Master Rigger's License to do said work, and that all work 
in connection therewith shall comply with applicable laws and regulations. Any 
such moving shall be at the sole risk and hazard of Tenant and Tenant will 
defend, indemnify and save Landlord harmless against and from any liability, 
loss, injury, claim or suit resulting directly or indirectly from such 
moving. Proper placement of all such business machines, etc., in the premises 
shall be Tenant's responsibility.

15. INSURANCE, INDEMNIFICATION, EXONERATION AND EXCULPATION

    15.1   GENERAL LIABILITY INSURANCE. Tenant shall procure, and keep in 
force and pay for Commercial General Liability Insurance insuring Tenant on 
an occurrence basis against all claims and demands for personal injury 
liability (including, without limitation, bodily injury, sickness, disease, 
and death) or damage to property which may be claimed to have occurred from 
and after the time Tenant and/or its contractors enter the premises in 
accordance with Article 4 of this Lease, of not less than Two Million 
($2,000,000) Dollars in the event of personal injury to any number of persons 
or damage to

                                       -17-
<PAGE>

property, arising out of any one occurrence, and from time to time thereafter 
shall be not less than such higher amounts, if procurable, as may be 
reasonably required by Landlord and are customarily carried by responsible 
similar tenants in the City or Town wherein the Building is located.

    15.2   CERTIFICATES OF INSURANCE. Such insurance shall be effected with 
insurers approved by Landlord, authorized to do business in the State wherein 
the Building is situated under valid and enforceable policies wherein Tenant 
names Landlord and Landlord's managing agent as additional insureds. Such 
insurance shall provide that it shall not be canceled or modified without at 
least thirty (30) days' prior written notice to each insured named therein. On 
or before the time Tenant and/or its contractors enter the premises in 
accordance with Articles 4 and 14 of this Lease and thereafter not less than 
fifteen (15) days prior to the expiration date of each expiring policy, 
original copies of the policies provided for in Article 15.1 issued by the 
respective insurers, or certificates of such policies setting forth in full 
the provisions thereof and issued by such insurers together with evidence 
satisfactory to Landlord of the payment of all premiums for such policies, 
shall be delivered by Tenant to Landlord and certificates as aforesaid of 
such policies shall upon request of Landlord, be delivered by Tenant to the 
holder of any mortgage affecting the premises.

    15.3   GENERAL. Tenant will save Landlord, its agents and employees, 
harmless and will exonerate, defend and indemnify Landlord, its agents and 
employees, from and against any and all claims, liabilities or penalties 
asserted by or on behalf of any person, firm, corporation or public authority 
arising from the Tenant's breach of the Lease or:

           (a)   On account of or based upon any injury to person, or loss of 
or damage to property, sustained or occurring on the premises on account of 
or based upon the act, omission, fault, negligence or misconduct of any 
person whomsoever (except to the extent the same is caused by Landlord, its 
agents, contractors or employees);

           (b)   On account of or based upon any injury to person, or loss of 
or damage to property, sustained or occurring elsewhere (other than on the 
premises) in or about the Building (and, in particular, without limiting the 
generality of the foregoing, on or about the elevators, stairways, public 
corridors, sidewalks, concourses, arcades, malls, galleries, vehicular 
tunnels, approaches, areaways, roof, or other appurtenances and facilities 
used in connection with the Building or premises) arising out of the use or 
occupancy of the Building or premises by the Tenant, or by any person 
claiming by, through or under Tenant, or on account of or based upon the act, 
omission, fault, negligence or misconduct of Tenant, its agents, employees or 
contractors; and

           (c)   On account of or based upon (including monies due on account 
of) any work or thing whatsoever done (other than by Landlord or its 
contractors, or agents or employees of either) on the premises during the 
term of this Lease and during the period of time, if any, prior to the Term 
Commencement Date that Tenant may have been given access to the premises.

           (d)   Tenant's obligations under this Article 15.3 shall be 
insured either under the Commercial General Liability Insurance required 
under Article 15.1, above, or by a contractual insurance rider or other 
coverage; and certificates of insurance in respect thereof shall be provided 
by Tenant to Landlord upon request.

    15.4   PROPERTY OF TENANT. In addition to and not in limitation of the 
foregoing, Tenant covenants and agrees that, to the maximum extent permitted 
by law, all merchandise, furniture, fixtures and property of every kind, 
nature and description related or arising out of Tenant's leasehold estate 
hereunder, which may be in or upon the premises or Building, in the public 
corridors, or on the sidewalks, areaways and approaches adjacent thereto, 
shall be at the sole risk and hazard of Tenant, and that if the whole or any

                                       -18-
<PAGE>

part thereof shall be damaged, destroyed, stolen or removed from any cause or 
reason whatsoever no part of said damage or loss shall be charged to, or 
borne by, Landlord.

    15.5   BURSTING OF PIPES, ETC. Landlord shall not be liable for any 
injury or damage to persons or property resulting from fire, explosion, 
falling plaster, steam, gas, air contaminants or emissions, electricity, 
electrical or electronic emanations or disturbance, water, rain or snow or 
leaks from any part of the Building or from the pipes, appliances, equipment 
or plumbing works or from the roof, street or sub-surface or from any other 
place or caused by dampness, vandalism, malicious mischief or by any other 
cause of whatever nature, unless caused by or due to the negligence of 
Landlord, its agents, servants or employees, and then only after (i) notice 
to Landlord of the condition claimed to constitute negligence and (ii) the 
expiration of a reasonable time after such notice has been received by 
Landlord without Landlord having taken all reasonable and practicable means 
to cure or correct such condition; and pending such cure or correction by 
Landlord, Tenant shall take all reasonably prudent temporary measures and 
safeguards to prevent any injury, loss or damage to persons or property. In 
no event shall Landlord be liable for any loss, the risk of which is covered 
by Tenant's insurance or is required to be so covered by this Lease; nor 
shall Landlord or its agents be liable for any such damage caused by other 
tenants or persons in the Building or caused by operations in construction of 
any private, public, or quasi-public work; nor shall Landlord be liable for 
any latent defect in the premises or in the Building.

    15.6   REPAIRS AND ALTERATIONS--NO DIMINUTION OF RENTAL VALUE. Except as 
otherwise provided in Article 18, there shall be no allowance to Tenant for 
diminution of rental value and no liability on the part of Landlord by reason 
of inconvenience, annoyance or injury to Tenant arising from any repairs, 
alterations, additions, replacements or improvements made by Landlord, Tenant 
or others in or to any portion of the Building or premises or any property 
adjoining the Building, or in or to fixtures, appurtenances, or equipment 
thereof, or for failure of Landlord or others to make any repairs, 
alterations, additions or improvements in or to any portion of the Building, 
or of the premises, or in or to the fixtures, appurtenances or equipment 
thereof.

16. ASSIGNMENT, MORTGAGING AND SUBLETTING

    Tenant covenants and agrees that neither this Lease nor the term and 
estate hereby granted, nor any interest herein or therein, will be assigned, 
mortgaged, pledged, encumbered or otherwise transferred, voluntarily, by 
operation of law or otherwise, and that neither the premises, nor any part 
thereof will be encumbered in any manner by reason of any act or omission on 
the part of Tenant, or used or occupied, or permitted to be used or occupied, 
or utilized for desk space or for mailing privileges, by anyone other than 
Tenant, or for any use or purpose other than as stated in Exhibit 1, or be 
sublet, or offered or advertised for subletting. Notwithstanding the 
foregoing, it is hereby expressly understood and agreed however, if Tenant is 
a corporation, that the assignment or transfer of this Lease, and the term 
and estate hereby granted, to any corporation into which Tenant is merged or 
with which Tenant is consolidated which corporation shall have a net worth at 
least equal to that of Tenant immediately prior to such merger or 
consolidation (such corporation being hereinafter called "Assignee"), shall 
not be deemed to be prohibited hereby if, and upon the express condition that 
Assignee and Tenant shall promptly execute, acknowledge and deliver to 
Landlord an agreement in form and substance satisfactory to Landlord whereby 
Assignee shall agree to be independently bound by and upon all the covenants, 
agreements, terms, provisions and conditions set forth in this Lease on the 
part of Tenant to be performed, and whereby Assignee shall expressly agree 
that the provisions of this Article 16 shall, notwithstanding such assignment 
or transfer, continue to be binding upon it with respect to all future 
assignments and transfers.

    If Tenant is an individual who uses and/or occupies the premises with 
partners, or if Tenant is a partnership, then:

                                       -19-
<PAGE>

           (i)   Each present and future partner shall be personally bound by 
and upon all of the covenants, agreements, terms, provisions and conditions 
set forth in this Lease on the part of Tenant to be performed; and 

           (ii)  In confirmation of the foregoing, Landlord may (but without 
being required to do so) request (and Tenant shall duly comply) that Tenant, 
at the time that Tenant admits any new partner to its partnership, shall 
require each such new partner to execute an agreement in form and substance 
satisfactory to Landlord whereby such new partner shall agree to be personally 
bound by and upon all of the covenants, agreements, terms, provisions and 
conditions of this Lease on the part of Tenant to be performed, without regard 
to the time when such new partner is admitted to partnership or when any 
obligations under any such covenants, etc., accrue.

    The listing of any name other than that of Tenant, whether on the doors 
of the premises or on the Building directory, or otherwise, shall not operate 
to vest in any such other person, firm or corporation any right or interest 
in this Lease or in the premises or be deemed to effect or evidence any consent 
of Landlord, it being expressly understood that any such listing is a 
privilege extended by Landlord revocable at will by written notice to Tenant.

    If this Lease be assigned, or if the premises or any part thereof be 
sublet or occupied by anybody other than Tenant, Landlord may, at any time and
from time to time, collect rent and other charges from the assignee, 
subtenant or occupant, and apply the net amount collected to the rent and 
other charges herein reserved then due and thereafter becoming due, but no 
such assignment, subletting, occupancy or collection shall be deemed a waiver 
of this covenant, or the acceptance of the assignee, subtenant or occupant as 
a tenant, or a release of Tenant from the further performance by Tenant of 
covenants on the part of Tenant herein contained. Any consent by Landlord to 
a particular assignment or subletting shall not in any way diminish the 
prohibition stated in the first sentence of this Article 16 or the continuing 
liability of the Tenant named on Exhibit 1 as the party Tenant under this 
Lease. No assignment or subletting shall affect the purpose for which the 
premises may be used as stated in Exhibit 1.

17. MISCELLANEOUS COVENANTS

    Tenant covenants and agrees as follows:

    17.1   RULES AND REGULATIONS. Tenant will faithfully observe and comply 
with the Rules and Regulations, if any, annexed hereto and such other and 
further reasonable Rules and Regulations as Landlord hereafter at any time or 
from time to time may make and may communicate in writing to Tenant, which in 
the reasonable judgment of Landlord shall be necessary for the reputation, 
safety, care or appearance of the Building, or the preservation of good order 
therein, or the operation or maintenance of the Building, or the equipment 
thereof, or the comfort of tenants or others in the Building, provided, 
however, that in the case of any conflict between the provisions of this 
Lease and any such regulations, the provisions of this Lease shall control, 
and provided further that nothing contained in this Lease shall be construed 
to impose upon Landlord any duty or obligation to enforce the Rules and 
Regulations or the terms, covenants or conditions in any other lease as 
against any other tenant and Landlord shall not be liable to Tenant for 
violation of the same by any other tenant, its servants, employees, agents, 
contractors, visitors, invitees or licensees.

    17.2   ACCESS TO PREMISES--SHORING. Tenant shall: (i) permit Landlord to 
erect, use and maintain pipes, ducts and conduits in and through the 
premises, provided the same do not materially reduce the floor area or 
materially adversely affect the appearance thereof; (ii) upon prior oral 
notice (except that no notice shall be required in emergency situations), 
permit Landlord and any mortgagee of the Building or the Building and land or 
of the interest of Landlord therein, and any lessor under any ground or 
underlying lease, and their representatives, to have free and unrestricted 
access to and to enter upon the premises at all

                                       -20-
<PAGE>

reasonable hours for the purposes of inspection or of making repairs, 
replacements or improvements in or to the premises or the Building or 
equipment (including, without limitation, sanitary, electrical, heating, air 
conditioning or other systems) or of complying with all laws, orders and 
requirements of governmental or other authority or of exercising any right 
reserved to Landlord by this Lease (including the right during the progress 
of any such repairs, replacements or improvements or while performing work 
and furnishing materials in connection with compliance with any such laws, 
orders or requirements to take upon or through, or to keep and store within, 
the premises all necessary materials, tools and equipment); and (iii) permit 
Landlord, at reasonable times, to show the premises during ordinary business 
hours to any existing or prospective mortgagee, ground lessor, space lessee, 
purchaser, or assignee of any mortgage, of the Building or of the Building 
and the land or of the interest of Landlord therein, and during the period of 
12 months next preceding the Termination Date to any person contemplating 
the leasing of the premises or any part thereof. If, during the last month of 
the term, Tenant shall have removed all or substantially all of Tenant's 
property therefrom, Landlord may immediately enter and alter, renovate and 
redecorate the premises, without elimination or abatement of rent, or 
incurring liability to Tenant for any compensation, and such acts shall have 
no effect upon this Lease. If Tenant shall not be personally present to open 
and permit an entry into the premises at any time when for any reason an 
entry therein shall be necessary or permissible, Landlord or Landlord's 
agents may enter the same by a master key, or may forcibly enter the same, 
without rendering Landlord or such agents liable therefor (if during such entry 
Landlord or Landlord's agents shall accord reasonable care to Tenant's 
property), and without in any manner affecting the obligations and covenants 
of this Lease. Provided that Landlord shall incur no additional expense 
thereby, Landlord shall exercise its rights of access to the premises 
permitted under any of the terms and provisions of this Lease in such manner 
as to minimize to the extent practicable interference with Tenant's use and 
occupation of the premises. If an excavation shall be made upon land adjacent 
to the premises or shall be authorized to be made, Tenant shall afford to the 
person causing or authorized to cause such excavation, license to enter upon 
the premises for the purpose of doing such work as said person shall deem 
necessary to preserve the Building from injury or damage and to support the 
same by proper foundations without any claims for damages or indemnity 
against Landlord, or diminution or abatement of rent.

    17.3   ACCIDENTS TO SANITARY AND OTHER SYSTEMS. Tenant shall give to 
Landlord prompt notice of any fire or accident in the premises or in the 
Building and of any damage to, or defective condition in, any part or 
appurtenance of the Building including, without limitation, sanitary, 
electrical, ventilation, heating and air conditioning or other systems 
located in, or passing through, the premises. Except as otherwise provided in 
Articles 18 and 20, and subject to Tenant's obligations in Article 14, such 
damage or defective condition shall be remedied by Landlord with reasonable 
diligence, but if such damage or defective condition was caused by Tenant or 
by the employees, licensees, contractors or invitees of Tenant, the cost to 
remedy the same shall be paid by Tenant. In addition, all reasonable costs 
incurred by Landlord in connection with the investigation of any notice 
given by Tenant shall be paid by Tenant if the reported damage or defective 
condition was caused by Tenant or by the employees, licensees, contractors, 
or invitees of Tenant. Tenant shall not be entitled to claim any eviction 
from the premises or any damages arising from any such damage or defect 
unless the same (i) shall have been occasioned by the negligence of the 
Landlord, its agents, servants or employees and (ii) shall not, after notice 
to Landlord of the condition claimed to constitute negligence, have been 
cured or corrected within a reasonable time after such notice has been 
received by Landlord; and in case of a claim of eviction unless such damage 
or defective condition shall have rendered the premises untenantable and they 
shall not have been made tenantable by Landlord within a reasonable time.

    17.4   SIGNS, BLINDS AND DRAPES. Tenant shall put no signs in any part of 
the Building. No signs or blinds may be put on or in any window or elsewhere 
if visible from the exterior of the Building, nor may the building standard 
drapes or blinds be removed by Tenant. Tenant may hang its own drapes, 
provided that they shall not in any way interfere with the building standard 
drapery or blinds or be visible from the exterior of the Building and that 
such drapes are so hung and installed that when drawn, the

                                       -21-

<PAGE>

building standard drapery or blinds are automatically also drawn. Any signs 
or lettering in the public corridors or on the doors shall conform to 
Landlord's building standard design. Neither Landlord's name, nor the name of 
the Building or the Park, or the name of any other structure erected therein 
shall be used without Landlord's consent in any advertising material (except 
on business stationery or as an address in advertising matter), nor shall any 
such name, as aforesaid, be used in any undignified, confusing, detrimental 
or misleading manner.

    17.5   ESTOPPEL CERTIFICATE. Tenant shall at any time and from time to 
time upon not less than ten (10) days' prior notice by Landlord to Tenant, 
execute, acknowledge and deliver to Landlord a statement in writing 
certifying that this Lease is unmodified and in full force and effect (or if 
there have been modifications, that the same is in full force and effect as 
modified and stating the modifications), and the dates to which the Yearly 
Rent and other charges have been paid in advance, if any, stating whether or 
not Landlord is in default in performance of any covenant, agreement, term, 
provision or condition contained in this Lease and, if so, specifying each 
such default and such other facts as Landlord may reasonably request, it 
being intended that any such statement delivered pursuant hereto may be 
relied upon by any prospective purchaser of the Building or of the Building 
and the land or of any interest of Landlord therein, any mortgagee or 
prospective mortgagee thereof, any lessor or prospective lessor thereof, any 
lessee or prospective lessee thereof, or any prospective assignee of any 
mortgage thereof. Time is of the essence in respect of any such requested 
certificate, Tenant hereby acknowledging the importance of such certificates 
in mortgage financing arrangements, prospective sale and the like. Tenant 
hereby appoints Landlord Tenant's attorney-in-fact in its name and behalf to 
execute such statement  if Tenant shall fail to execute such statement within 
such ten-(10)-day period.

    17.6   PROHIBITED MATERIALS AND PROPERTY. Tenant shall not bring or 
permit to be brought or kept in or on the premises or elsewhere in the 
Building (i)  any inflammable, combustible or explosive fluid, material, 
chemical or substance including, without limitation, any hazardous substances 
as defined under Massachusetts General Laws chapter 21E, the Federal 
Comprehensive Environmental Response Compensation and Liability Act (CERCLA), 
42 USC Section 9601 ET SEQ., as amended, under Section 3001 of the Federal 
Resource Conservation and Recovery Act of 1976, as amended, or under any 
regulation of any governmental authority regulating environmental or health 
matters (except for standard office supplies stored in proper containers), 
(ii) any materials, appliances or equipment (including, without limitation, 
materials, appliances and equipment selected by Tenant for the construction 
or other preparation of the premises and furniture and carpeting) which pose 
any danger to life, safety or health or may cause damage, injury or death; 
(iii) any unique, unusually valuable, rare or exotic property, work of art or 
the like unless the same is fully insured under all-risk coverage, or (iv) 
any data processing, electronic, optical or other equipment or property of a 
delicate, fragile or vulnerable nature unless the same are housed, shielded 
and protected against harm and damage, whether by cleaning or maintenance 
personnel, radiations or emanations from other equipment now or hereafter 
installed in the Building, or otherwise. Nor shall Tenant cause or permit any 
potentially harmful air emissions, odors of cooking or other processes, or 
any unusual or other objectionable odors or emissions to emanate from or 
permeate the premises.

    17.7.  REQUIREMENTS OF LAW--FINES AND PENALTIES. Tenant at its sole 
expense shall comply with all laws, rules, orders and regulations, including, 
without limitation, all energy-related requirements, of Federal, State, 
County and Municipal Authorities and with any direction of any public officer 
or officers, pursuant to law, which shall impose any duty upon Landlord or 
Tenant with respect to or arising out of Tenant's use or occupancy of the 
premises. Tenant shall reimburse and compensate Landlord for all expenditures 
made by, or damages or fines sustained or incurred by, Landlord due to 
nonperformance or noncompliance with or breach or failure to observe any 
item, covenant, or condition of this Lease upon Tenant's part to be kept, 
observed, performed or complied with. If Tenant receives notice of any 
violation of law, ordinance, order or regulation applicable to the premises, 
it shall give prompt notice thereof to Landlord.

    17.8   TENANT'S ACTS--EFFECT ON INSURANCE. Tenant shall not do or permit 
to be done any act or thing upon the premises or elsewhere in the Building 
which will invalidate or be in conflict with any insurance policies covering 
the Building and the fixtures and property therein; and shall not do, or 
permit to be done, any act or thing upon the premises which shall subject 
Landlord to any liability or responsibility for injury to any person or 
persons or to property by reason of any business or operation being carried 
on upon said premises or for any other reason. Tenant at its own expense 
shall comply with all rules, orders, regulations and requirements of the 
Board of Fire Underwriters, or any other similar body having jurisdiction, 
and shall not (i) do, or permit anything to be done, in or upon the premises, 
or bring or keep anything therein, except as now or hereafter permitted by 
the Fire Department, Board of Underwriters, Fire Insurance Rating 
Organization, or other authority having jurisdiction, and then only in such 
quantity and manner of storage as will not increase the rate for any 
insurance applicable to the Building, or (ii) use the premises in a manner 
which shall increase such insurance rates on the Building, or on property 
located therein, over that applicable when Tenant first took occupancy of the 
premises hereunder. If by reason of the failure of Tenant to comply with the 
provisions hereof the insurance rate applicable to any policy of insurance 
shall at any time thereafter be higher than it otherwise would be, the Tenant 
shall reimburse Landlord for that part of any insurance premiums thereafter 
paid by Landlord, which shall have been charged because of such failure by 
Tenant.

    17.9   MISCELLANEOUS. Tenant shall not suffer or permit the premises or 
any fixtures, equipment or utilities therein or serving the same, to be 
overloaded, damaged or defaced, nor permit any hole to be drilled or made in 
any part thereof. Tenant shall not suffer or permit any employee, contractor, 
business invitee or visitor to violate any covenant, agreement or obligations 
of the Tenant under this Lease.

18. DAMAGE BY FIRE, ETC.

    During the entire term of this Lease, and adjusting insurance coverages 
to reflect current values from time to time:--(i) Landlord shall keep the 
Building (excluding work, installations, improvements and betterments in the 
premises which exceed the specifications provided in Exhibit 3, 
[called "Over-Building-Standard Property"] and any other property installed 
by or at the expense of Tenant) insured against loss or damage caused by any 
peril covered under fire, extended coverage and all risk insurance in an 
amount equal to one hundred percent (100%) of the full insurable value 
thereof above foundation walls; and (ii) Tenant shall keep its personal 
property in and about the premises and the Over-Building-Standard Property 
insured against loss or damage caused by any peril covered under fire, 
extended coverage and all risk insurance in an amount equal to one hundred 
percent (100%) of the full insurable value thereof. Such Tenant's insurance 
shall insure the interests of both Landlord and Tenant as their respective 
interests may appear from time to time and shall name Landlord as an 
additional insured; and the proceeds thereof shall be used only for the 
replacement or restoration of such personal property and the 
Over-Building-Standard Property.

    If any portion of the premises required to be insured by Landlord under 
the preceding paragraph shall be damaged by fire or other insured casualty, 
Landlord shall proceed with diligence, subject to the then applicable 
statutes, building codes, zoning ordinances, and regulations of any 
governmental authority, and at the expense of Landlord (but only to the 
extent of insurance proceeds made available to Landlord by any mortgagee 
and/or ground lessor of the real property of which the premises are a part) 
to repair or cause to be repaired such damage, provided, however, in respect 
of any Over-Building Standard Property as shall have been damaged by such 
fire or other casualty and which (in the judgment of Landlord) can more 
effectively be repaired as an integral part of Landlord's repair work on the 
premises, that such repairs to such Tenant's alterations, decorations, 
additions and improvements shall be performed by Landlord but at Tenant's 
expense; in all other respects, all repairs to and replacements of Tenant's 
property and Over-Building-Standard Property shall be made by and at the 
expense of Tenant. If the premises or any part thereof shall have been 
rendered unfit for use and occupation hereunder by reason of such damage the 
Yearly Rent or a just and proportionate part thereof, according to the nature 
and extent to which the

                                       -23-
<PAGE>

premises shall have been so rendered unfit, shall be suspended or abated 
until the premises (except as to the property which is to be repaired by or 
at the expense of Tenant) shall have been restored as nearly as practicably 
may be to the condition in which they were immediately prior to such fire or 
other casualty, provided, however, that if Landlord or any mortgagee of the 
Building or of the Building and the land shall be unable to collect the 
insurance proceeds (including rent insurance proceeds) applicable to such 
damage because of some action or inaction on the part of Tenant, or the 
employees, licensees or invitees of Tenant, the cost of repairing such damage 
shall be paid by Tenant and there shall be no abatement of rent. Landlord 
shall not be liable for delays in the making of any such repairs which are 
due to government regulation, casualties and strikes, unavailability of labor 
and materials, and other causes beyond the reasonable control of Landlord, 
nor shall Landlord be liable for any inconvenience or annoyance to Tenant or 
injury to the business of Tenant resulting from delays in repairing such 
damage. If (i) the premises are so damaged by fire or other casualty (whether 
or not insured) at any time during the last thirty months of the term hereof 
that the cost to repair such damage is reasonably estimated to exceed one 
third of the total Yearly Rent payable hereunder for the period from the 
estimated date of restoration until the Termination Date, or (ii) the 
Building (whether or not including any portion of the premises) is so damaged 
by fire or other casualty (whether or not insured) that substantial 
alteration or reconstruction or demolition of the Building shall in 
Landlord's judgment be required, then and in either of such events, this 
Lease and the term hereof may be terminated at the election of Landlord by a 
notice in writing of its election so to terminate which shall be given by 
Landlord to Tenant within sixty (60) days following such fire or other 
casualty, the effective termination date of which shall be not less than 
thirty (30) days after the day on which such termination notice is received 
by Tenant. In the event of any termination, this Lease and the term hereof 
shall expire as of such effective termination date as though that were the 
Termination Date as stated in Exhibit 1 and the Yearly Rent shall be 
apportioned as of such date; and if the premises or any part thereof shall 
have been rendered unfit for use and occupation by reason of such damage the 
Yearly Rent for the period from the date of the fire or other casualty to the 
effective termination date, or a just and proportionate part thereof, 
according to the nature and extent to which the premises shall have been so 
rendered unfit, shall be abated.

19. WAIVER OF SUBROGATION

    In any case in which Tenant shall be obligated to pay to Landlord any 
loss, cost, damage, liability or expense suffered or incurred by Landlord, 
Landlord shall allow to Tenant as an offset against the amount thereof (i) 
the net proceeds of any insurance collected by Landlord for or on account of 
such loss, cost, damage, liability or expense, provided that the allowance of 
such offset does not invalidate or prejudice the policy or policies under 
which such proceeds were payable, and (ii) if such loss, cost, damage, 
liability or expense shall have been caused by a peril against which Landlord 
has agreed to procure insurance coverage under the terms of this Lease, the 
amount of such insurance coverage, whether or not actually procured by 
Landlord.

    In any case in which Landlord or Landlord's managing agent shall be 
obligated to pay to Tenant any loss, cost, damage, liability or expense 
suffered or incurred by Tenant, Tenant shall allow to Landlord or Landlord's 
managing agent, as the case may be, as an offset against the amount thereof 
(i) the net proceeds of any insurance collected by Tenant for or on account 
of such loss, cost, damage, liability, or expense, provided that the 
allowance of such offset does not invalidate the policy or policies under 
which such proceeds were payable and (ii) the amount of any loss, cost, 
damage, liability or expense caused by a peril covered by fire insurance with 
the broadest form of property insurance generally available on property in 
buildings of the type of the Building, whether or not actually procured by 
Tenant.

    The parties hereto shall each procure an appropriate clause in, or 
endorsement on, any property insurance policy covering the premises and the 
Building and personal property, fixtures and equipment located thereon and 
therein, pursuant to which the insurance companies waive subrogation or 
consent to a waiver of right of recovery in favor of either party, its 
respective agents or employees. Having obtained

                                       -24-
<PAGE>

such clauses and/or endorsements, each party hereby agrees that it will not 
make any claim against or seek to recover from the other or its agents or 
employees for any loss or damage to its property or the property of others 
resulting from fire or other perils covered by such property insurance.

20. CONDEMNATION - EMINENT DOMAIN

    In the event that the premises or any part thereof, or the whole or any 
part of the Building, shall be taken or appropriated by eminent domain or 
shall be condemned for any public or quasi-public use, or (by virtue of any 
such taking, appropriation or condemnation) shall suffer any damage (direct, 
indirect or consequential) for which Landlord or Tenant shall be entitled to 
compensation, then (and in any such event) this Lease and the term hereof may 
be terminated at the election of Landlord by a notice in writing of its 
election so to terminate which shall be given by Landlord to Tenant within 
sixty (60) days following the date on which Landlord shall have received 
notice of such taking, appropriation or condemnation. In the event that a 
substantial part of the premises or of the means of access thereto shall be 
so taken, appropriated or condemned, then (and in any such event) this Lease 
and the term hereof may be terminated at the election of Tenant by a notice 
in writing of its election so to terminate which shall be given by Tenant to 
Landlord within sixty (60) days following the date on which Tenant shall have 
received notice of such taking, appropriation or condemnation.

    Upon the giving of any such notice of termination (either by Landlord or 
Tenant) this Lease and the term hereof shall terminate on or retroactively as 
of the date on which Tenant shall be required to vacate any part of the 
premises or shall be deprived of a substantial part of the means of access 
thereto, provided, however, that Landlord may in Landlord's notice elect to 
terminate this Lease and the term hereof retroactively as of the date on which 
such taking, appropriation or condemnation became legally effective. In the 
event of any such termination, this Lease and the term hereof shall expire as 
of such effective termination date as though that were the Termination Date as 
stated in Exhibit 1, and the Yearly Rent shall be apportioned as of such date. 
If neither party (having the right so to do) elects to terminate Landlord 
will, with reasonable diligence and at Landlord's expense, restore the 
remainder of the premises, or the remainder of the means of access, as 
nearly as practicably may be to the same condition as obtained prior to such 
taking, appropriation or condemnation in which event (i) the Total Rentable 
Area shall be equitably adjusted, (ii) a just proportion of the Yearly Rent, 
according to the nature and extent of the taking, appropriation or 
condemnation and the resulting permanent injury to the premises and the means 
of access thereto, shall be permanently abated, and (iii) a just proportion  
of the remainder of the Yearly Rent, according to the nature and extent of 
the taking, appropriation or condemnation and the resultant injury sustained 
by the premises and the means of access thereto, shall be abated until what 
remains of the premises and the means of access thereto shall have been 
restored as fully as may be for permanent use and occupation by Tenant 
hereunder. Except for any award specifically reimbursing Tenant for moving or 
relocation expenses, there are expressly reserved to Landlord all rights to 
compensation and damages created, accrued or accruing by reason of any such 
taking, appropriation or condemnation, in implementation and in confirmation 
of which Tenant does hereby acknowledge that Landlord shall be entitled to 
receive all such compensation and damages, grant to Landlord all and whatever 
rights (if any) Tenant may have to such compensation and damages, and agree 
to execute and deliver all and whatever further instruments of assignment as 
Landlord may from time to time request. In the event of any taking of the 
premises or any part thereof for temporary (i.e., not in excess of one (1) 
year) use, (i) this Lease shall be and remain unaffected thereby, and (ii) 
Tenant shall be entitled to receive for itself any award made to the extent 
allocable to the premises in respect of such taking on account of such use, 
provided, that if any taking is for a period extending beyond the term of this 
Lease, such award shall be apportioned between Landlord and Tenant as of the 
Termination Date or earlier termination of this Lease.

21. DEFAULT

                                       -25-
<PAGE>

    21.1   CONDITIONS OF LIMITATION - RE-ENTRY - TERMINATION. This Lease and 
the herein term and estate are, upon the condition that if (a) subject to 
Article 21.7, Tenant shall neglect or fail to perform or observe any of the 
Tenant's covenants or agreements herein, including (without limitation) the 
covenants or agreements with regard to the payment when due of rent, 
additional charges, reimbursement for increase in Landlord's costs, or any 
other charge payable by Tenant to Landlord (all of which shall be considered 
as part of Yearly Rent for the purposes of invoking Landlord's statutory or 
other rights and remedies in respect of payment defaults); or (b) Tenant 
shall desert or abandon the premises or the same shall become, or shall 
appear to have become, vacant (whether or not the keys shall have been 
surrendered or the rent shall have been paid); or (c) Tenant shall be 
involved in financial difficulties as evidenced by an admission in writing by 
Tenant of Tenant's inability to pay its debts generally as they become due, or 
by the making or offering to make a composition of its debts with its 
creditors; or (d) Tenant shall make an assignment or trust mortgage, or other 
conveyance or transfer of like nature, of all or a substantial part of its 
property for the benefit of its creditors, or (e) an attachment on mesne 
process, on execution or otherwise, or other legal process shall issue 
against Tenant or its property and a sale of any of its assets shall be held 
thereunder; or (f) any judgment, final beyond appeal or any lien, attachment 
or the like shall be entered, recorded or filed against Tenant in any court, 
registry, etc. and Tenant shall fail to pay such judgment within thirty (30) 
days after the judgment shall have become final beyond appeal or to discharge 
or secure by surety bond such lien, attachment, etc. within thirty (30) days 
of such entry, recording or filing, as the case may be; or (g) the leasehold 
hereby created shall be taken on execution or by other process of law and 
shall not be revested in Tenant within thirty (30) days thereafter; or (h) a 
receiver, sequesterer, trustee or similar officer shall be appointed by a 
court of competent jurisdiction to take charge of all or any part of Tenant's 
property and such appointment shall not be vacated within thirty (30) days; 
or (i) any proceeding shall be instituted by or against Tenant pursuant to 
any of the provisions of any Act of Congress or State law relating to 
bankruptcy, reorganizations, arrangements, compositions or other relief from 
creditors, and, in the case of any proceeding instituted against it, if Tenant 
shall fail to have such proceedings dismissed within thirty (30) days or if 
Tenant is adjudged bankrupt or insolvent as a result of any such proceeding, 
or (j) any event shall occur or any contingency shall arise whereby this 
Lease, or the term and estate thereby created, would (by operation of law or 
otherwise) devolve upon or pass to any person, firm or corporation other 
than Tenant, except as expressly permitted under Article 16 hereof - then, 
and in any such event (except as hereinafter in Article 21.2 otherwise 
provided) Landlord may, by notice to Tenant, elect to terminate this Lease; 
and thereupon (and without prejudice to any remedies which might otherwise be 
available for arrears of rent or other charges due hereunder or preceding 
breach of covenant or agreement and without prejudice to Tenant's liability 
for damages as hereinafter stated), upon the giving of such notice, this 
Lease shall terminate as of the date specified therein as though that were 
the Termination Date as stated in Exhibit 1. Without being taken or deemed to 
be guilty of any manner of trespass or conversion, and without being liable 
to indictment, prosecution or damages therefor, Landlord may, forcibly if 
necessary, enter into and upon the premises (or any part thereof in the name 
of the whole); repossess the same as of its former estate; and expel Tenant 
and those claiming under Tenant. Wherever "Tenant" is used in subdivisions 
(c), (d), (e), (f), (g), (h) and (i) of this Article 21.1, it shall be deemed 
to include any one of (i) any corporation of which Tenant is a controlled 
subsidiary and (ii) any guarantor of any of Tenant's obligations under this 
Lease. The words "re-entry" and "re-enter" as used in this Lease are not 
restricted to their technical legal meanings.

    21.2   DAMAGES - ASSIGNMENT FOR BENEFIT OF CREDITORS. For the more 
effectual securing to Landlord of the rent and other charges and payments 
reserved hereunder, it is agreed as a further condition of this Lease that if 
at any time Tenant shall make any transfer similar to or in the nature of an 
assignment of its property for the benefit of its creditors, the term and 
estate hereby created shall terminate ipso facto, without entry or other 
action by Landlord; and notwithstanding any other provisions of this Lease, 
Landlord shall forthwith upon such termination, without prejudice to any 
remedies which might otherwise be available for arrears of rent or other 
charges due hereunder or preceding breach of this Lease, be ipso facto 
entitled to recover as liquidated damages the sum of (a) the amount described 
in clause (x) of Article 21.3 and (b) (in view of the uncertainty of prompt 
re-letting and the expense entailed in re-letting the

                                       -26-

<PAGE>

premises) an amount equal to the rent and other charges payable for and in 
respect of the twelve-(12)-month period next preceding the date of 
termination, as aforesaid.

     21.3  DAMAGES - TERMINATION. Upon the termination of this Lease under 
the provisions of this Article 21, then except as hereinabove in Article 21.2 
otherwise provided, Tenant shall pay to Landlord the rent and other charges 
payable by Tenant to Landlord up to the time of such termination, shall 
continue to be liable for any preceding breach of covenant, and in addition, 
shall pay to Landlord as damages, at the election of Landlord

    either:

           (x)   the amount by which, at the time of the termination of this 
Lease (or at any time thereafter if Landlord shall have initially elected 
damages under subparagraph (y), below), (i) the aggregate of the rent and 
other charges projected over the period commencing with such termination and 
ending on the Termination Date as stated in Exhibit 1 exceeds (ii) the 
aggregate projected rental value of the premises for such period;

    or:

          (y)    amounts equal to the rent and other charges which would have 
been payable by Tenant had this Lease not been so terminated, payable upon 
the due dates therefore specified herein following such termination and until 
the Termination Date as specified in Exhibit 1, provided, however, if 
Landlord shall re-let the premises during such period, that Landlord shall 
credit Tenant with the net rents received by Landlord from such re-letting, 
such net rents to be determined by first deducting from the gross rents as 
and when received by Landlord from such re-letting the expenses incurred or 
paid by Landlord in terminating this Lease, as well as the expenses of 
re-letting, including altering and preparing the premises for new tenants, 
brokers' commissions, and all other similar and dissimilar expenses properly 
chargeable against the premises and the rental therefrom, it being understood 
that any such re-letting may be for a period equal to or shorter or longer 
than the remaining term of this Lease: and provided, further, that (i) in no 
event shall Tenant be entitled to receive any excess of such net rents over 
the sums payable by Tenant to Landlord hereunder and (ii) in no event shall 
Tenant be entitled in any suit for the collection of damages pursuant to this 
Subparagraph (y) to a credit in respect of any net rents from a re-letting 
except to the extent that such net rents are actually received by Landlord 
prior to the commencement of such suit. If the premises or any part thereof 
should be re-let in combination with other space, then proper apportionment 
on a square foot area basis shall be made of the rent received from such 
re-letting and of the expenses of re-letting.

     In calculating the rent and other charges under Subparagraph (x), above, 
there shall be included, in addition to the Yearly Rent, Tax Excess and 
Operating Expense Excess and all other considerations agreed to be paid or 
performed by Tenant, on the assumption that all such amounts and 
considerations would have remained constant (except as herein otherwise 
provided) for the balance of the full term hereby granted.

     Suit or suits for the recovery of such damages, or any installments 
thereof, may be brought by Landlord from time to time at its election, and 
nothing contained herein shall be deemed to require Landlord to postpone suit 
until the date when the term of this Lease would have expired if it had not 
been terminated hereunder.

     Nothing herein contained shall be construed as limiting or precluding 
the recovery by Landlord against Tenant of any sums or damages to which, in 
addition to the damages particularly provided above, Landlord may lawfully be 
entitled by reason of any default hereunder on the part of Tenant.

                                       -27-

<PAGE>

     21.4  FEES AND EXPENSES.

           (a)   If Tenant shall default in the performance of any covenant 
on Tenant's part to be performed as in this Lease contained, Landlord may 
immediately, or at any time thereafter, without notice, perform the same for 
the account of Tenant. If Landlord at any time is compelled to pay or elects 
to pay any sum of money, or do any act which will require the payment of any 
sum of money, by reason of the failure of Tenant to comply with any provision 
hereof, or if Landlord is compelled to or does incur any expense, including 
reasonable attorneys' fees, in instituting, prosecuting, and/or defending any 
action or proceeding instituted by reason of any default of Tenant hereunder, 
Tenant shall on demand pay to Landlord by way of reimbursement the sum or 
sums so paid by Landlord with all costs and damages, plus interest computed 
as provided in Article 6 hereof.

           (b)   Tenant shall pay Landlord's cost and expense, including 
reasonable attorneys' fees, incurred (i) in enforcing any obligation of 
Tenant under this Lease or (ii) as a result of Landlord, without its fault, 
being made party to any litigation pending by or against Tenant or any 
persons claiming through or under Tenant.

    21.5   WAIVER OF REDEMPTION. Tenant does hereby waive and surrender all 
rights and privileges which it might have under or by reason of any present 
or future law to redeem the premises or to have a continuance of this Lease 
for the term hereby demised after being dispossessed or ejected therefrom by 
process of law or under the terms of this Lease or after the termination of 
this Lease as herein provided.

    21.6   LANDLORD'S REMEDIES NOT EXCLUSIVE. The specified remedies to which 
Landlord may resort hereunder are cumulative and are not intended to be 
exclusive of any remedies or means of redress to which Landlord may at any 
time be lawfully entitled, and Landlord may invoke any remedy (including the 
remedy of specific performance) allowed at law or in equity as if specific 
remedies were not herein provided for.

    21.7   GRACE PERIOD. Notwithstanding anything to the contrary in this 
Article contained, Landlord agrees not to take any action to terminate this 
Lease (a) for default by Tenant in the payment when due of any sum of money, 
if Tenant shall cure such default within ten (10) days after written notice 
thereof is given by Landlord to Tenant, provided, however, that no such 
notice need be given and no such default in the payment of money shall be 
curable if on two (2) prior occasions there had been a default in the payment 
of money which had been cured after notice thereof had been given by Landlord 
to Tenant as herein provided or (b) for default by Tenant in the performance 
of any covenant other than a covenant to pay a sum of money, if Tenant shall 
cure such default within a period of thirty (30) days after written notice 
thereof given by Landlord to Tenant (except where the nature of the default 
is such that remedial action should appropriately take place sooner, as 
indicated in such written notice), or within such additional period as may 
reasonably be required to cure such default if (because of governmental 
restrictions or any other cause beyond the reasonable control of Tenant) the 
default is of such a nature that it cannot be cured within such 
thirty-(30)-day period, however, (1) that there shall be no extension of time 
beyond such thirty-(30)-day period for the curing of any such default unless, 
not more than ten (10) days after the receipt of the notice of default. 
Tenant in writing (i) shall specify the cause on account of which the default 
cannot be cured during such period and shall advise Landlord of its intention 
duly to institute all steps necessary to cure the default and (ii) shall, as 
soon as reasonably practicable, duly institute and thereafter diligently 
prosecute to completion all steps necessary to cure such default and, (2) 
that no notice of the opportunity to cure a default need be given, and no 
grace period whatsoever shall be allowed to Tenant, if the default is 
incurable or if the covenant or condition the breach of which gave rise to 
default had, by reason of a breach on a prior occasion, been the subject of a 
notice hereunder to cure such default.

                                       -28-

<PAGE>

    Notwithstanding anything to the contrary in this Article 21.7 contained, 
except to the extent prohibited by applicable law, any statutory notice and 
grace periods provided to Tenant by law are hereby expressly waived by Tenant.

22. END OF TERM - ABANDONED PROPERTY

    Upon the expiration or other termination of the term of this Lease, 
Tenant shall peaceably quit and surrender to Landlord the premises and all 
alterations and additions thereto, broom clean, in good order, repair and 
condition (except as provided herein and in Articles 8.7, 18 and 20) 
excepting only ordinary wear and use and damage by fire or other casualty for 
which, under other provisions of this Lease, Tenant has no responsibility of 
repair or restoration. Tenant shall remove all of its property and, to the 
extent specified by Landlord, all alterations and additions made by Tenant 
and all partitions wholly within the premises, and shall repair any damages 
to the premises or the Building caused by their installation or by such 
removal.  Tenant's obligation to observe or perform this covenant shall 
survive the expiration or other termination of the term of this Lease.

    Tenant will remove any personal property from the Building and the 
premises upon or prior to the expiration or termination of this Lease and any 
such property which shall remain in the Building or the premises thereafter 
shall be conclusively deemed to have been abandoned, and may either be 
retained by Landlord as its property or sold or otherwise disposed of in such 
manner as Landlord may see fit. If any part thereof shall be sold, that 
Landlord may receive and retain the proceeds of such sale and apply the same, 
at its option, against the expenses of the sale, the cost of moving and 
storage, any arrears of Yearly Rent, additional or other charges hereunder by 
Tenant to Landlord and any damages to which Landlord may be entitled under 
Article 21 hereof or pursuant to law.

    If Tenant or anyone claiming under Tenant shall remain in possession of 
the premises or any part thereof after the expiration or prior termination of 
the term of this Lease without any agreement in writing between Landlord and 
Tenant with respect thereto, then, prior to the acceptance of any payments 
for rent or use and occupancy by Landlord, the person remaining in possession 
shall be deemed a tenant-at-sufferance. Whereas the parties hereby 
acknowledge that Landlord may need the premises after the expiration or prior 
termination of the term of the Lease for other tenants and that the damages 
which Landlord may suffer as the result of Tenant's holding-over cannot be 
determined as of the Execution Date hereof, in the event that Tenant so holds 
over, Tenant shall pay to Landlord, for each month or portion thereof that 
Tenant shall retain possession of the premises after the expiration or 
termination of the Lease, whether by lapse of time or otherwise, in addition 
to all rental and other charges due and accrued under the Lease prior to the 
date of termination, use and occupancy charges equal to one hundred fifty 
percent (150%) of the greater of (a) the then fair market rent for the 
premises as conclusively determined by Landlord or (b) the sum of the Yearly 
Rent and additional rent at the rate payable monthly during the twelve (12) 
months immediately preceding the expiration or termination of the Lease. In 
addition, Tenant shall hold Landlord harmless from all damages which Landlord 
may suffer as the result of Tenant's holdover after the termination of the 
term of the Lease.

23. SUBORDINATION

    (a)    Subject to any mortgagee's or ground lessor's election, as 
hereinafter provided for, this Lease is subject and subordinate in all 
respects to all matters of record (including, without limitation, deeds and 
land disposition agreements), ground leases and/or underlying leases, and all 
mortgages, any of which may now or hereafter be placed on or affect such 
leases and/or the real property of which the premises are a part, or any part 
of such real property, and/or Landlord's interest or estate therein, and to 
each advance made and/or hereafter to be made under such mortgages, and to 
all renewals, modifications, consolidations, replacements and extensions 
thereof and all substitutions therefor. This Article 23 shall be 
self-operative and no further instrument or subordination shall be required. 
In confirmation of such

                                        -29-

<PAGE>

subordination, Tenant shall execute, acknowledge and deliver promptly any 
certificate or instrument that Landlord and/or any mortgagee and/or lessor 
under any ground or underlying lease and/or their respective successors in 
interest may request, subject to Landlord's, mortgagee's and ground lessor's 
right to do so for, on behalf and in the name of Tenant under certain 
circumstances, as hereinafter provided. Tenant acknowledges that, where 
applicable, any consent or approval hereafter given by Landlord may be 
subject to the further consent or approval of such mortgagee and/or ground 
lessor; and the failure or refusal of such mortgagee and/or ground lessor to 
give such consent or approval shall, notwithstanding anything to the contrary 
in this Lease contained, constitute reasonable justification for Landlord's 
withholding its consent or approval.

   (b)     Any such mortgagee or ground lessor may from time to time 
subordinate or revoke any such subordination of the mortgage or ground lease 
held by it to this Lease.  Such subordination or revocation, as the case may 
be, shall be effected by written notice to Tenant and by recording an 
instrument of subordinations or of such revocation, as the case may be, with 
the appropriate registry of deeds or land records and to be effective without 
any further act or deed on the part of Tenant. In confirmation of such 
subordination or of such revocation, as the case may be, Tenant shall 
execute, acknowledge and promptly deliver any certificate or instrument that 
Landlord, any mortgagee or ground lessor may request, subject to Landlord's, 
mortgagee's and ground lessor's right to do so for, on behalf and in the name 
of Tenant under certain circumstances, as hereafter provided.

    (c)    Without limitation of any of the provisions of this Lease, if any 
ground lease or mortgagee shall succeed to the interest of Landlord by reason 
of the exercise of its rights under such ground lease or mortgage (or the 
acceptance of voluntary conveyance in lieu thereof) or any third party 
(including, without limitation, any foreclosure purchaser or mortgage 
receiver) shall succeed to such interest by reason of any such exercise or 
the expiration or sooner termination of such ground lease, however caused, 
then such successor may, upon notice and request to Tenant (which, in the 
case of a ground lease, shall be within thirty (30) days after such 
expiration or sooner termination), succeed to the interest of Landlord under 
this Lease, provided, however, that such successor shall not: (i) be liable 
for any previous act or omission of Landlord under this Lease; (ii) be 
subject to any offset, defense, or counterclaim which shall theretofore have 
accrued to Tenant against Landlord; (iii) have any obligation with respect to 
any security deposit unless it shall have been paid over or physically 
delivered to such successor; or (iv) be bound by a previous modification of 
this Lease or by any previous payment of Yearly Rent for a period greater 
than one (1) month, made without such ground lessor's or mortgagee's consent 
where such consent is required by applicable ground lease or mortgage 
documents. In the event of such succession to the interest of the Landlord -- 
and notwithstanding that any such mortgage or ground lease may antedate this 
Lease -- the Tenant shall attorn to such successor and shall ipso facto be 
and become bound directly to such successor in interest to Landlord to 
perform and observe all the Tenant's obligations under this Lease without the 
necessity of the execution of any further instrument. Nevertheless, Tenant 
agrees at any time and from time to time during the term hereof to execute a 
suitable instrument in confirmation of Tenant's agreement to attorn, as 
aforesaid, subject to Landlord's, mortgagee's and ground lessor's right to do 
so for, on behalf and in the name of Tenant under certain circumstances, as 
hereinafter provided.

    (d)    The term "mortgage(s)" as used in this Lease shall include any 
mortgage or deed of trust.  The term "mortgagee(s)" as used in this Lease 
shall include any mortgages or any trustee and beneficiary under a deed of 
trust or receiver appointed under a mortgage or deed of trust. The term 
"mortgagor(s)" as used in this Lease shall include any mortgage or any 
grantor under a deed of trust.

    (c)    Tenant hereby irrevocably constitutes and appoints Landlord or any 
such mortgagee or ground lessor, and their respective successors in interest, 
acting singly, Tenant's attorney-in-fact to execute and deliver any such 
certificate or instrument for, on behalf and in the name of Tenant, but only 
if Tenant

                                       -30-

<PAGE>

fails to execute, acknowledge and deliver any such certificate or instrument 
within ten (10) days after Landlord or such mortgagee or such ground lessor 
has made written request therefor.

    (f)    Notwithstanding anything to the contrary contained in this Article 
23, if all or part of Landlord's estate and interest in the real property of 
which the premises are a part shall be a leasehold estate held under a ground 
lease, then: (i) the foregoing subordination provisions of this Article 23 
shall not apply to any mortgages of the fee interest in said real property to 
which Landlord's leasehold estate is not otherwise subject and subordinate; 
and (ii) the provisions of this Article 23 shall in no way waive, abrogate or 
otherwise affect any agreement by any ground lessor (x) not to terminate this 
Lease incident to any termination of such ground lease prior to its term 
expiring or (y) not to name or join Tenant in any action or proceeding by 
such ground lessor to recover possession of such real property or for any 
other relief.

    (g)    In the event of any failure by Landlord to perform, fulfill or 
observe any agreement by Landlord herein, in no event will the Landlord be 
deemed to be in default under this Lease permitting Tenant to exercise any or 
all rights or remedies under this Lease until the Tenant shall have given 
written notice of such failure to any mortgagee (ground lessor and/or 
trustee) of which Tenant shall have been advised and until a reasonable 
period of time shall have elapsed following the giving of such notice, during 
which such mortgagee (ground lessor and/or trustee) shall have the right, but 
shall not be obligated, to remedy such failure.

24. QUIET ENJOYMENT

    Landlord covenants that if, and so long as, Tenant keeps and performs 
each and every covenant, agreement, term, provision and condition herein 
contained on the part and on behalf of Tenant to be kept and performed, 
Tenant shall quietly enjoy the premises from and against the claims of all 
persons claiming by, through or under Landlord subject, nevertheless, to the 
covenants, agreements, terms, provisions and conditions of this Lease and to 
the mortgages, ground leases and/or underlying leases to which this Lease is 
subject and subordinate, as hereinabove set forth.

    Without incurring any liability to Tenant, Landlord may permit access to 
the premises and open the same, whether or not Tenant shall be present, upon 
any demand of any receiver, trustee, assignee for the benefit of creditors, 
sheriff, marshal or court officer entitled to, or reasonably purporting to be 
entitled to, such access for the purpose of taking possession of, or 
removing, Tenant's property or for any other lawful purpose (but this 
provision and any action by Landlord hereunder shall not be deemed a 
recognition by Landlord that the person or official making such demand has 
any right or interest in or to this Lease, or in or to the premises), or upon 
demand of any representative of the fire, police, building, sanitation or 
other department of the city, state or federal governments.

25. ENTIRE AGREEMENT -- WAIVER -- SURRENDER

    25.1   ENTIRE AGREEMENT. This Lease and the Exhibits made a part hereof 
contain the entire and only agreement between the parties and any and all 
statements and representations, written and oral, including previous 
correspondence and agreements between the parties hereto, are merged herein. 
Tenant acknowledges that all representations and statements upon which it 
relied in executing this Lease are contained herein and that the Tenant in no 
way relied upon any other statements or representations, written or oral. Any 
executory agreement hereafter made shall be ineffective to change, modify, 
discharge or effect an abandonment of this Lease in whole or in part unless 
such executory agreement is in writing and signed by the party against whom 
enforcement of the change, modification, discharge or abandonment is sought.

                                       -31-

<PAGE>

    25.2   WAIVER BY LANDLORD. The failure of Landlord to seek redress for 
violation, or to insist upon the strict performance, of any covenant or 
condition of this Lease, or any of the Rules and Regulations promulgated 
hereunder, shall not prevent a subsequent act, which would have originally 
constituted a violation, from having all the force and effect of an original 
violation. The receipt by Landlord of rent with knowledge of the breach of 
any covenant of this Lease shall not be deemed a waiver of such breach. The 
failure of Landlord to enforce any of such Rules and Regulations against 
Tenant and/or any other tenant in the Building shall not be deemed a waiver 
of any such Rules and Regulations. No provisions of this Lease shall be 
deemed to have been waived by Landlord unless such waiver be in writing 
signed by Landlord. No payment by Tenant or receipt by Landlord of a lesser 
amount than the monthly rent herein stipulated shall be deemed to be other 
than on account of the stipulated rent, nor shall any endorsement or 
statement on any check or any letter accompanying any check or payment as 
rent be deemed an accord and satisfaction, and Landlord may accept such check 
or payment without prejudice to Landlord's right to recover the balance of 
such rent or pursue any other remedy in this Lease provided.

    25.3   SURRENDER. No act or thing done by Landlord during the term hereby 
demised shall be deemed an acceptance of a surrender of the premises, and no 
agreement to accept such surrender shall be valid, unless in writing signed 
by Landlord. No employee of Landlord or of Landlord's agents shall have any 
power to accept the keys of the premises prior to the termination of this 
Lease. The delivery of keys to any employee of Landlord or of Landlord's 
agents shall not operate as a termination of the Lease or a surrender of the 
premises. In the event that Tenant at any time desires to have Landlord 
underlet the premises for Tenant's account, Landlord or Landlord's agents are 
authorized to receive the keys for such purposes without releasing Tenant 
from any of the obligations under this Lease, and Tenant hereby relieves 
Landlord of any liability for loss of or damage to any of Tenant's effects in 
connection with such underletting.

26. INABILITY TO PERFORM - EXCULPATORY CLAUSE

    Except as provided in Article 4.1 and 4.2 hereof, this Lease and the 
obligations of Tenant to pay rent hereunder and perform all the other 
covenants, agreements, terms, provisions and conditions hereunder on the part 
of Tenant to be performed shall in no way be affected, impaired or excused 
because Landlord is unable to fulfill any of its obligations under this Lease 
or is unable to supply or is delayed in supplying any service expressly or 
impliedly to be supplied or is unable to make or is delayed in making any 
repairs, replacements, additions, alterations, improvements or decorations or 
is unable to supply or is delayed in supplying any equipment or fixtures if 
Landlord is prevented or delayed from so doing by reason of strikes or labor 
troubles or any other similar or dissimilar cause whatsoever beyond 
Landlord's reasonable control, including but not limited to, governmental 
preemption in connection with a national emergency or by reason of any rule, 
order or regulation of any department or subdivision thereof of any 
governmental agency or by reason of the conditions of supply and demand which 
have been or are affected by war, hostilities or other similar or dissimilar 
emergency. In each such instance of inability of Landlord to perform, 
Landlord shall exercise reasonable diligence to eliminate the cause of such 
inability to perform.

    Tenant shall neither assert nor seek to enforce any claim against 
Landlord, or Landlord's agents or employees, or the assets of Landlord or of 
Landlord's agents or employees, for breach of this Lease or otherwise, other 
than against Landlord's interest in the Building of which the premises are a 
part and in the uncollected rents, issues and profits thereof, and Tenant 
agrees to look solely to such interest for the satisfaction of any liability 
of Landlord under this Lease, it being specifically agreed that in no event 
shall Landlord or Landlord's agents or employees (or any of the officers, 
trustees, directors, partners, beneficiaries, joint venturers, members, 
stockholders or other principals or representatives, and the like, disclosed or 
undisclosed, thereof) ever be personally liable for any such liability. This 
paragraph shall not limit any right that Tenant might otherwise have to 
obtain injunctive relief against Landlord or to take any other action which 
shall not involve the personal liability of Landlord to respond in monetary 
damages from Landlord's assets other than the Landlord's interest in said 
real estate, as aforesaid. In no event shall

                                       -32-

<PAGE>

Landlord or Landlord's agents or employees (or any of the officers, trustees, 
directors, partners, beneficiaries, joint venturers, members, stockholders or 
other principals or representatives and the like, disclosed or undisclosed, 
thereof) ever be liable for loss of profits, loss of the value of Tenant's 
business, or consequential or incidental damages. Without limiting the 
foregoing, in no event shall Landlord or Landlord's agents or employees (or 
any of the officers, trustees, directors, partners, beneficiaries, joint 
venturers, members, stockholders or other principals or representatives and 
the like, disclosed or undisclosed, thereof) ever be liable for lost profits 
of Tenant. If by reason of Landlord's failure to acquire title to the real 
property of which the premises are a part or to complete construction of the 
Building or premises, Landlord shall be held to be in breach of this Lease, 
Tenant's sole and exclusive remedy shall be a right to terminate this Lease.

27. BILLS AND NOTICES

    Any notice, consent, request, bill, demand or statement hereunder by 
either party to the other party shall be in writing and, if received at 
Landlord's or Tenant's address, shall be deemed to have been duly given when 
either delivered or served personally or mailed in a postpaid envelope, 
deposited in the United States mail addressed to Landlord at its address as 
stated in Exhibit 1 and to Tenant at the premises (or at Tenant's address as 
stated in Exhibit 1, if mailed prior to Tenant's occupancy of the premises), 
or if any address for notices shall have been duly changed as hereinafter 
provided, if mailed as aforesaid to the party at such changed address. Either 
party may at any time change the address or specify an additional address for 
such notices, consents, requests, bills, demands or statements by delivering 
or mailing, as aforesaid, to the other party a notice stating the change and 
setting forth the changed or additional address, provided such changed or 
additional address is within the United States.

    If Tenant is a partnership, Tenant, for itself, and on behalf of all of 
its partners, hereby appoints Tenant's Service Partner, as identified on 
Exhibit 1, to accept service of any notice, consent, request, bill, demand or 
statement hereunder by Landlord and any service of process in any judicial 
proceeding with respect to this Lease on behalf of Tenant and as agent and 
attorney-in-fact for each partner of Tenant.

    All bills and statements for reimbursement or other payments or charges 
due from Tenant to landlord hereunder shall be due and payable in full ten 
(10) days, unless herein otherwise provided, after submission thereof by 
Landlord to Tenant. Tenant's failure to make timely payment of any amounts 
indicated by such bills and statements, whether for work done by Landlord at 
Tenant's request, reimbursement provided for by this Lease or for any other 
sums properly owing by Tenant to Landlord, shall be treated as a default in 
the payment of rent, in which event Landlord shall have all rights and 
remedies provided in this Lease for the nonpayment of rent.

28. PARTIES BOUND -- SEISIN OF TITLE

    The covenants, agreements, terms, provisions and conditions of this Lease 
shall bind and benefit the successors and assigns of the parties hereto with 
the same effect as if mentioned in each instance where a party hereto is 
named or referred to, except that no violation of the provisions of Article 
16 hereof shall operate to vest any rights in any successor or assignee of 
Tenant and that the provisions of this Article 28 shall not be construed as 
modifying the conditions of limitation contained in Article 21 hereof.

    If, in connection with or as a consequence of the sale, transfer or other 
disposition of the real estate (land and/or Building, either or both, as the 
case may be) of which the premises are a part, Landlord ceases to be the 
owner of the reversionary interest in the premises. Landlord shall be 
entirely freed and relieved from the performance and observance thereafter of 
all covenants and obligations hereunder on the part of Landlord to be 
performed and observed, it being understood and agreed in such event (and it 
shall be deemed and construed as a covenant running with the land) that the 
person succeeding to Landlord's

                                       -33-

<PAGE>

ownership of said reversionary interest shall thereupon and thereafter 
assume, and perform and observe, any and all of such covenants and 
obligations of Landlord.

29. MISCELLANEOUS

    29.1   SEPARABILITY. If any provision of this Lease or portion of such 
provision or the application thereof to any person or circumstance is for any 
reason held invalid or unenforceable, the remainder of the Lease (or the 
remainder of such provision) and the application thereof to other persons or 
circumstances shall not be affected thereby.

    29.2   CAPTIONS, ETC. The captions are inserted only as a matter of 
convenience and for reference, and in no way define, limit or describe the 
scope of this Lease nor the intent of any provisions thereof. References to 
"State" shall mean, where appropriate, the District of Columbia and other 
Federal territories, possessions, as well as a state of the United States.

    29.3   BROKER. Tenant represents and warrants that it has not directly or 
indirectly dealt, with respect to the leasing of office space in the Building 
or the Park with any broker or had its attention called to the premises or 
other space to let in the Building or the Park, by anyone other than the 
broker, person or firm, if any, designated in Exhibit 1. Tenant agrees to 
defend, exonerate and save harmless and indemnify Landlord and anyone 
claiming by, through or under Landlord against any claims for a commission 
arising out of the execution and delivery of this Lease or out of 
negotiations between Landlord and Tenant with respect to the leasing of other 
space in the Building or the Park, provided that Landlord shall be solely 
responsible for the payment of brokerage commissions to the broker, person or 
firm, if any, designated in Exhibit 1.

    29.4   MODIFICATIONS. If in connection with obtaining financing for the 
Building, a bank, insurance company, pension trust or other institutional 
lender shall request reasonable modifications in this Lease as a condition to 
such financing, Tenant will not withhold, delay or condition its consent 
thereto, provided that such modifications do not increase the obligations of 
Tenant hereunder or materially adversely affect the leasehold interest hereby 
created.

    29.5   ARBITRATION. Any disputes relating to provisions or obligations in 
this Lease as to which a specific provision for a reference to arbitration is 
made herein shall be submitted to arbitration in accordance with the 
provisions of applicable state law (as identified on Exhibit 1), as from time 
to time amended. Arbitration proceedings, including the selection of an 
arbitrator, shall be conducted pursuant to the rules, regulations and 
procedures from time to time in effect as promulgated by the American 
Arbitration Association. Prior written notice of application by either party 
for arbitration shall be given to the other at least ten (10) days before 
submission of the application to the said Association's office in the City 
wherein the Building is situated (or the nearest other city having an 
Association office). The arbitrator shall hear the parties and their 
evidence. The decision of the arbitrator shall be binding and conclusive, and 
judgment upon the award or decision of the arbitrator may be entered in the 
appropriate court of law (as identified on Exhibit 1); and the parties 
consent to the jurisdiction of such court and further agree that any process 
or notice of motion or other application to the Court or a Judge thereof may 
be served outside the State wherein the Building is situated by registered 
mail or by personal service, provided a reasonable time for appearance is 
allowed. The costs and expenses of each arbitration hereunder and their 
apportionment between the parties shall be determined by the arbitrator in 
his award or decision. No arbitrable dispute shall be deemed to have arisen 
under this Lease prior to (i) the expiration of the period of twenty (20) 
days after the date of the giving of written notice by the party asserting 
the existence of the dispute together with a description thereof sufficient 
for an understanding thereof; and (ii) where a Tenant payment (e.g., Tax 
Excess or Operating Expense Excess under Article 9 hereof) is in issue, the 
amount billed by Landlord having been paid by Tenant.

                                       -34-

<PAGE>

    29.6   GOVERNING LAW. This Lease is made pursuant to, and shall be 
governed by, and construed in accordance with, the laws of the State wherein 
the Building is situated and any applicable local municipal rules, 
regulations, by-laws, ordinances and the like.

    29.7   ASSIGNMENT OF RENTS. With reference to any assignment by Landlord 
of its interest in the Lease, or the rents payable hereunder, conditional in 
nature or otherwise, which assignment is made to or held by a bank, trust 
company, insurance company or other institutional lender holding a mortgage 
or ground lease on the Building, Tenant agrees:

           (a)   that the execution thereof by Landlord and the acceptance 
thereof by such mortgagee and/or ground lessor shall never be deemed and 
assumption by such mortgagee and/or ground lessor of any of the obligations 
of the Landlord thereunder, unless such mortgagee and/or ground lessor shall, 
by written notice sent to the Tenant, specifically otherwise elect; and

           (b)   that, except as aforesaid, such mortgagee and/or ground 
lessor shall be treated as having assumed the Landlord's obligations 
thereunder only upon foreclosure of such mortgagee's mortgage or deed of 
trust or termination of such ground lessor's ground lease and the taking of 
possession of the demised premises after having given notice of its exercise 
of the option stated in Article 23 hereof to succeed to the interest of the 
landlord under this Lease.

    29.8   REPRESENTATION OF AUTHORITY. By his execution hereof each of the 
signatories on behalf of the respective parties hereby warrants and 
represents to the other that he is duly authorized to execute this lease on 
behalf of such party. If Tenant is a corporation, Tenant hereby appoints the 
signatory whose name appears below on behalf of Tenant as Tenant's 
attorney-in-fact for the purpose of executing this Lease for and on behalf of 
Tenant.

    29.9   EXPENSES INCURRED BY LANDLORD UPON TENANT REQUESTS. Tenant shall, 
upon demand, reimburse Landlord for all reasonable expenses, including, 
without limitation, legal fees, incurred by Landlord in connection with all 
requests by Tenant for consents, approvals or execution of collateral 
documentation related to this Lease, including, without limitation, costs 
incurred by landlord in the review and approval of Tenant's plans and 
specification in connection with proposed alterations to be made by Tenant to 
the premises, requests by Tenant to sublet the premises or assign its 
interest in the Lease, the execution by Landlord of estoppel certificates 
requested by Tenant, and requests by Tenant for Landlord to execute waivers 
of Landlord's interest in Tenant's property in connection with third party 
financing by Tenant. Such costs shall be deemed to be additional rent under 
the Lease.

    29.10  SURVIVAL. Without limiting any other obligation of the Tenant 
which may survive the expiration or prior termination of the term of the 
Lease, all obligations on the part of Tenant to indemnify, defend, or hold 
Landlord harmless, as set forth in the Lease (including, without limitation, 
Tenant's obligations under Articles 13(d), 15.3, and 29.3) shall survive the 
expiration or prior termination of the term of the Lease.

    29.11  NOTICE OF LEASE; RECORDING. 

           (a)   Tenant agrees not to record the Lease, but each party hereto 
agrees, at the request of the other, to execute a notice of lease in 
recordable form in compliance with applicable Massachusetts law and 
reasonably satisfactory to Landlord and attorneys. In no event shall such 
notice of lease set forth the rent or other charges payable by Tenant under 
the Lease; and such notice shall expressly state that it is executed pursuant 
to the provisions contained in the Lease, and is not intended to vary the 
terms and conditions of the Lease. It is hereby agreed that the requesting 
party shall pay all fees with respect to the recording of the notice of 
lease, the recording of any amendments thereto and the recording of any 
notice of termination thereof.

                                       -35-

<PAGE>

           (b)   If the Term Commencement Date and the Termination Date are 
not determined at the time that a notice of lease has been executed by the 
parties, then each of the parties hereto agrees, upon demand of the other 
party after the Term Commencement Date and Termination Date have been 
determined, to join in the execution, in recordable form, of a statutory 
notice, memorandum, etc. of lease and/or written declaration in which shall 
be stated such Term Commencement Date and (if need be) the Termination Date. 
If this Lease is terminated before the term expires, then upon Landlord's 
request the parties shall execute, deliver and record an instrument 
acknowledging such fact and the date of termination of this Lease, and Tenant 
hereby appoints Landlord its attorney-in-fact in its name and behalf to 
execute such instrument if Tenant shall fail to execute and deliver such 
instrument after Landlord's request therefor within ten (10) days.

    IN WITNESS WHEREOF the parties hereto have executed this Indenture of 
Lease in multiple copies, each to be considered an original hereof, as a 
sealed instrument on the day and year noted in Exhibit 1 as the Execution 
Date.

                                  BUILDING STANDARDS

                              New England Executive Park

The following exhibit sets forth "Building Standard" materials and finishes for
Tenant Improvement Work.  These are minimum standards.  Substitutions will be
allowed for equivalent quality and upgrading only and must be approved by the
Landlord, which approval shall not be unreasonably withheld.

1.   Partitions

     a.   Demising (type 'A')

          Partitions separating premises shall be constructed of 2 1/2" metal
          studs, 16" o.c., with two (2) layers of 5/8" wallboard on each side. 
          One layer on each side shall extend to the underside of the floor
          above.

     b.   Standard Partition (type 'B')

          Partitions separating spaces within single premises shall be
          constructed of 3 5/8" metal studs, 16" o.c., with one (1) layer of
          5/8" wallboard on each side.  Both layers shall extend 3" minimum
          above ceiling, unless otherwise required by applicable building
          codes.

     c.   Privacy Partition (type 'B-1')

          Where noise transmission is a concern within single premises (e.g.
          partitions separating conference rooms, high-traffic hallways, toilet
          rooms, and other such rooms from conference rooms or private
          offices), partitions shall be constructed of 3 5/8" metal studs, 16"
          o.c., with one (1) layer of 5/8" wallboard on each side.  One layer
          shall extend to the underside of the floor above and one layer shall

     for notifying its employees of this rule, and shall be responsible for any
     violation of this rule by its employees.

31.  In the event Landlord permits Tenant to hire its own contractors to perform
     any tenant construction work, Tenant shall make its contractors aware of
     these Rules and Regulations and shall be responsible for any violation of
     these Rules and Regulations by Tenant's contractors.

     be necessary for Tenant's employees to use their access cards to enter the
     Building on weekends and holidays.

                             RIDER TO LEASE


               LANDLORD: EOP-New England Executive Park L.L.C.,
                     a Delaware limited liability company
                 TENANT: The Quicksilver Group, Inc.

The subject Lease is hereby amended as follows:

1.  SECURITY FOR TENANT'S OBLIGATIONS UNDER LEASE

    Tenant shall, at the time that Tenant executes and delivers this Lease to 
Landlord, pay to Landlord, in order to secure Tenant's obligations under this 
Lease, a security deposit in the amount of Thirty-Five Thousand and 00/100 
($35,000.00) Dollars. In no event shall said security deposit be deemed to be 
a prepayment of rent nor shall it be considered a measure of liquidated 
damages. Tenant agrees that no interest shall accrue on said deposit and 
that Landlord shall have no obligation to maintain such deposit in a separate 
account (i.e. Landlord shall have the right to commingle such deposit with 
other funds of Landlord). In the event that Tenant shall default, beyond the 
expiration of applicable notice and grace periods, in any of its obligations 
under the Lease, Landlord shall have the right, without further notice to 
Tenant, to apply said deposit (or any portion thereof) towards the cure of 
any such default and Tenant shall promptly, upon notice from Landlord, pay to 
Landlord any amount so applied by Landlord in order to restore the full 
amount of said deposit. The application of all or any part of the deposit to 
any obligation or default of Tenant under this Lease shall not deprive 
Landlord of any other rights or remedies Landlord may have nor shall such 
application by Landlord constitute a waiver by Landlord. In addition, in the 
event of a termination based upon the default of Tenant under the Lease, or a 
rejection of the Lease pursuant to the provisions of the Federal Bankruptcy 
Code, Landlord shall have the right to apply the security deposit (from time 
to time, if necessary) to cover the full amount of damages and other amounts 
due from Tenant to Landlord under the Lease. Any amounts so applied shall, at 
Landlord's election, be applied first to any unpaid Yearly Rent and other 
charges which were due prior to the filing of the petition for protection 
under the Federal Bankruptcy Code. Provided that Tenant is not in default of 
any of its obligations under the Lease at the expiration of the term of the 
Lease, Landlord shall refund to Tenant any portion of said security deposit 
which Landlord is then holding.

     1.   LEASE AGREEMENT. On the terms stated in this Lease, Landlord leases
the Premises to Tenant, and Tenant leases the Premises from Landlord, for the
Term beginning on the Commencement Date and ending on the Termination Date
unless extended or sooner terminated pursuant to this Lease.

          A.   COMMENCEMENT DATE. The commencement date ("COMMENCEMENT DATE")
for this Lease is the date set forth in the Schedule. Notwithstanding the
foregoing, if Landlord is unable to deliver possession of the Premises to Tenant
on or before the Commencement Date for any reason, then (i) this Lease shall not
be void or voidable by either party, (ii) Landlord shall not be liable to Tenant
for any loss or damage resulting therefrom, and (iii) the Commencement Date
shall be revised to mean the date on which Landlord delivers possession of the
Premises to Tenant and the Termination Date shall be revised accordingly so that
the Term (as defined below) is unaffected by such delay.

          B.   TERMINATION DATE. If the Commencement Date is revised pursuant to
Section IA above, then the termination date ("TERMINATION DATE") of this Lease
shall be revised to mean the last date of the Term, as set forth in the
Schedule, after the revised Commencement Date, or if the revised Commencement
Date is not the first day of a month, then after the first day of the following
month.

          C.   EARLY OCCUPANCY. During the period commencing on September 24,
1998 and ending on the Commencement Date (the "EARLY OCCUPANCY PERIOD"), Tenant
shall be permitted to enter the Premises for the sole purpose of installing 
certain furniture, fixtures and equipment, provided that Tenant's occupancy of
the Premises during the Early Occupancy Period shall be subject to all of the
terms, covenants and conditions of this Lease (including, without limitation,
Tenant's obligations under Sections 5 (regarding obtaining Landlord's prior
written consent before commencing any alterations) and 9 (regarding Tenant's
indemnity and insurance obligations), except that Landlord agrees that Tenant's
obligation to pay Base Rent, Operating Cost Share Rent and Tax Share Rent (as
such terms are defined in Sections 2.B(1), (2) and (3) below) during the Early
Occupancy Period shall be waived.

     2.   RENT.

          A.   TYPES OF RENT. Tenant shall pay the following Rent pursuant to
instructions to be given to Tenant by Landlord prior to the Commencement Date:

               (1)    BASE RENT in monthly installments in advance, the first
monthly installment payable concurrently with the execution of this Lease and
thereafter on or before the first day of each month of the Term in the amount
set forth on the Schedule.

               (2)    OPERATING COST SHARE RENT in an amount equal to the
Tenant's Proportionate Share of the excess of Operating Costs for the applicable
fiscal year of the Lease (the "EXCESS OPERATING COSTS") over the Operating
Costs for the Base Year (the "BASE OPERATING COSTS"), paid monthly in advance in
an estimated amount. Definitions of Operating Costs and Tenant's Proportionate
Share, and the method for billing and payment of Operating Cost Share Rent are
set forth in Sections 2B, 2C and 2D.


                                          3

<PAGE>

               (3)    TAX SHARE RENT in an amount equal to the Tenant's
Proportionate Share of the excess of Taxes for the applicable fiscal year of
this Lease (the "EXCESS TAXES") over the Taxes for the Base Year (the "BASE
TAXES"), paid monthly in advance in an estimated amount. A definition of Taxes
and the method for billing and payment of Tax Share Rent are set forth in
Sections 2B, 2C and 2D.

               (4)    ADDITIONAL RENT in the amount of all costs, expenses,
liabilities, and amounts which Tenant is required to pay under this Lease,
excluding Base Rent, Operating Cost Share Rent, and Tax Share Rent, but
including any interest for late payment of any item of Rent.

               (5)    RENT as used in this Lease means Base Rent, Operating
Cost Share Rent, Tax Share Rent and Additional Rent. Tenant's agreement to pay
Rent is an independent covenant, with no right of setoff, deduction or
counterclaim of any kind.

          B.   PAYMENT OF OPERATING COST SHARE RENT AND TAX SHARE RENT.

               (1)    PAYMENT OF ESTIMATED OPERATING COST SHARE RENT AND TAX
SHARE RENT. Landlord shall estimate the Operating Costs and Taxes of the Project
by April 1 of each fiscal year, or as soon as reasonably possible thereafter.
Landlord may revise these estimates whenever it obtains more accurate
information, such as the final real estate tax assessment or tax rate for the
Project.

          Within ten (10) days after receiving the original or revised estimate
from Landlord setting forth (a) an estimate of Operating Costs for a particular
fiscal year, (b) the Base Operating Costs, and (c) the resulting estimate
of Excess Operating Costs for such fiscal year, Tenant shall pay Landlord
one-twelfth (1/12th) of Tenant's Proportionate Share of the estimated Excess
Operating Costs, multiplied by the number of months that have elapsed in the
applicable fiscal year to the date of such payment including the current month,
minus payments previously made by Tenant for the months elapsed. On the first
day of each month thereafter, Tenant shall pay Landlord one-twelfth (1/12th) of
Tenant's Proportionate Share of this estimate, until a new estimate becomes
applicable.

          Within ten (10) days after receiving the original or revised estimate
from Landlord setting forth (a) an estimate of Taxes for a particular fiscal
year, (b) the Base Taxes, and (c) the resulting estimate of Excess Taxes for
such fiscal year, Tenant shall pay Landlord one-twelfth (1/12th) of Tenant's
Proportionate Share of the estimated Excess Taxes, multiplied by the number of
months that have elapsed in the applicable fiscal year to the date of such
payment including the current month, minus payments previously made by Tenant
for the months elapsed. On the first day of each month thereafter, Tenant shall
pay Landlord one-twelfth (1/12th) of Tenant's Proportionate Share of this
estimate, until a new estimate becomes applicable.

               (2)    CORRECTION OF OPERATING COST SHARE RENT. Landlord shall
deliver to Tenant a report for the previous fiscal year (the "OPERATING COST
REPORT") by May 15th of each year, or as soon as reasonably possible thereafter,
setting forth (a) the actual Operating Costs incurred, (b) the Base Operating
Costs, (c) the amount of Operating Cost Share Rent due from Tenant, and (d) the
amount of Operating Cost Share Rent paid by Tenant. Within twenty (20) days
after such delivery, Tenant shall pay to Landlord the amount due minus the
amount paid. If the amount paid



                                          4

<PAGE>

exceeds the amount due, Landlord shall apply the excess to Tenant's payments of
Operating Cost Share Rent next coming due.

               (3)    CORRECTION OF TAX SHARE RENT. Landlord shall deliver to
Tenant a report for the previous fiscal year (the "TAX REPORT") by May 15th of
each year, or as soon as reasonably possible thereafter, setting forth (a) the
actual Taxes, (b) the Base Taxes, (c) the amount of Tax Share Rent due from
Tenant, and (d) the amount of Tax Share Rent paid by Tenant. Within twenty (20)
days after such delivery, Tenant shall pay to Landlord the amount due from
Tenant minus the amount paid by Tenant. If the amount paid exceeds the amount
due, Landlord shall apply any excess as a credit against Tenant's payments of
Tax Share Rent next coming due.

          C.   DEFINITIONS.

               (1)    INCLUDED OPERATING COSTS. "OPERATING COSTS" means any
expenses, costs and disbursements of any kind other than Taxes, paid or incurred
by Landlord in connection with the management, maintenance, operation, insurance
(including the related deductibles), repair and other related activities in
connection with any part of the Project and of the personal property, fixtures,
machinery, equipment, systems and apparatus used in connection therewith,
including the cost of providing those services required to be furnished by
Landlord under this Lease, and a reasonable management fee. Operating Costs
shall also include the costs of any capital improvements which are intended to
reduce Operating Costs or improve safety, and those made to keep the Project in
compliance with governmental requirements applicable from time to time or to
replace existing capital improvements, facilities and equipment within the
Building or the common areas of the Project, such as the roof membrane and
resurfacing of the parking areas (collectively, "INCLUDED CAPITAL ITEMS");
provided, that the costs of any Included Capital Item shall be amortized by
Landlord, together with an amount equal to interest at ten percent (10%) per
annum, over the estimated useful life of such item and such amortized costs are
only included in Operating Costs for that portion of the useful life of the
Included Capital Item which falls within the Term, unless the cost of the
Included Capital Item is less than Ten Thousand Dollars ($10,000) in which case
it shall be expensed in the year in which it was incurred.

          If the Project contains more than one building, then Operating Costs
shall include (i) all Operating Costs fairly allocable to the Building, and
(ii) a proportionate share (based on the gross rentable area of the Building as
a percentage of the gross rentable area of all of the Buildings in the Project)
of all Operating Costs which relate to the Project in general and are not fairly
allocable to any one building in the Project.

          If the Project is not fully occupied during any portion of any Fiscal
Year, Landlord may adjust (an "EQUITABLE ADJUSTMENT") Operating Costs to equal
what would have been incurred by Landlord had the Project been fully occupied.
This Equitable Adjustment shall apply only to Operating Costs which are variable
and therefore increase as occupancy of the Project increases. Landlord may
incorporate the Equitable Adjustment in its estimates of Operating Costs.

          If Landlord does not furnish any particular service whose cost would
have constituted an Operating Cost to a tenant other than Tenant who has
undertaken to perform such service itself, Operating Costs shall be increased by
the amount which Landlord would have incurred if it had furnished the service to
such tenant.

                              ground lease of the Project;

                      (d)     real estate brokers' leasing commissions;

                              Building or portions thereof;

                      (f)     any cost or expenditure for which Landlord is
                              reimbursed, by insurance proceeds or otherwise,
                              except by Operating Cost Share Rent;

                              tenant of the Project which Landlord does not make

                              construction materials and equipment installed in
                              the Building in light of their specifications);

                      (k)     legal and auditing fees which are for the benefit
                              of Landlord such as collecting delinquent rents,
                              preparing tax returns and other financial
                              statements, and audits other than those incurred
                              in connection with the preparation of reports
                              required pursuant to Section 2B above;

                      (l)     the wages of any employee for services not related
                              directly to the management, maintenance, operation
                              and repair of the Building; and

                      (m)     fines, penalties and interest.

               (3)    TAXES. "TAXES" means any and all taxes, assessments and
charges of any kind, general or special, ordinary or extraordinary, levied
against the Project which Landlord

<PAGE>

shall pay or become obligated to pay in connection with the ownership, leasing,
renting, management, use, occupancy, control or operation of the Project or of
the personal property, fixtures, machinery, equipment, systems and apparatus
used in connection therewith. Taxes shall include real estate taxes, personal
property taxes, sewer rents, water rents, special or general assessments,
transit taxes, ad valorem taxes, and any tax levied on the rents hereunder or
the interest of Landlord under this Lease (the "RENT TAX"). Taxes shall also
include all fees and other costs and expenses paid by Landlord in reviewing any
tax and in seeking a refund or reduction of any Taxes, whether or not the
Landlord is ultimately successful. Taxes shall also include any assessments or
fees paid to any business park owners association, or similar entity, which are
imposed against the Project pursuant to any Covenants, Conditions and
Restrictions ("CC&R's") recorded against the Project and any installments of
principal and interest required to pay any existing or future general or special
assessments for public improvements, services or benefits, and any increases
resulting from reassessments imposed in connection with any change in ownership
or new construction.

          If the Project contains more than one building, then Taxes shall
include (i) all Taxes fairly allocable to the Building, and (ii) a proportionate
share (based on the gross rentable area of the Building as a percentage of the
gross rentable area of all of the Buildings in the Project) of all Taxes which
relate to the Project in general and are not fairly allocable to any one
building in the Project.

          For any year, the amount to be included in Taxes (a) from taxes or
assessments payable in installments, shall be the amount of the installments
(with any interest) due and payable during such year, and (b) from all other
Taxes, shall at Landlord's election be the amount accrued, assessed, or
otherwise imposed for such year or the amount due and payable in such year. Any
refund or other adjustment to any Taxes by the taxing authority, shall apply
during the year in which the adjustment is made. Taxes shall not include any net
income (except Rent Tax), capital, stock, succession, transfer, franchise, gift,
estate or inheritance tax, except to the extent that such tax shall be imposed
in lieu of any portion of Taxes.

               (4)    LEASE YEAR. "LEASE YEAR" means each consecutive
twelve-month period beginning with the Commencement Date, except that if the

               (1)    PRORATIONS. If this Lease begins on a day other than the
first day of a month, the Base Rent, Operating Cost Share Rent and Tax Share
Rent shall be prorated for such partial month based on the actual number of days
in such month. If this Lease begins on a day other than the first day, or ends
on a day other than the last day, of the Fiscal Year, Operating Cost Share Rent
and Tax Share Rent shall be prorated for the applicable Fiscal Year.


                                          7

<PAGE>

               (2)    DEFAULT INTEREST. Any sum due from Tenant to Landlord not
paid when due shall bear interest from the date due until paid at the lesser of
eighteen percent (18%) per annum or the maximum rate permitted by law.

               (3)    RENT ADJUSTMENTS. The square footage of the Premises and
the Building set forth in the Schedule are conclusively deemed to be the actual
square footage thereof, without regard to any subsequent remeasurement of the
Premises or the Building. If any Operating Cost paid in one Fiscal Year relates
to more than one Fiscal Year, Landlord may proportionately allocate such
Operating Cost among the related Fiscal Years.

               (4)    BOOKS AND RECORDS. Landlord shall maintain books and
records reflecting the Operating Costs and Taxes in accordance with sound
accounting and management practices. Tenant and its certified public accountant
shall have the right to inspect Landlord's records at Landlord's applicable
local office or other location designated by Landlord upon at least seventy-two
(72) hours' prior notice during normal business hours during the ninety (90)
days following the respective delivery of the Operating Cost Report or the Tax
Report. The results of any such inspection shall be kept strictly confidential
by Tenant and its agents, and Tenant and its certified public accountant must
agree, in their contract for such services, to such confidentiality restrictions
and shall specifically agree that the results shall not be made available to any
other tenant of the Project. Unless Tenant sends to Landlord any written
exception to either such report within said ninety (90) day period, such report
shall be deemed final and accepted by Tenant. Tenant shall pay the amount shown
on both reports in the manner prescribed in this Lease, whether or not Tenant
takes any such written exception, Without any prejudice to such exception. If
Tenant makes a timely exception, Landlord shall cause its independent certified
public accountant to issue a final and conclusive resolution of Tenant's
exception. Tenant shall pay the cost of such certification unless Landlord's
original determination of annual Operating Costs and Taxes in the aggregate
overstated the amounts thereof by more than five percent (5%).

               (5)    MISCELLANEOUS. So long as Tenant is in default of any
obligation under this Lease, Tenant shall not be entitled to any refund of any
amount from Landlord. If this Lease is terminated for any reason prior to the
annual determination of Operating Cost Share Rent or Tax Share Rent, either
party shall pay the full amount due to the other within fifteen (15) days after
Landlord's notice to Tenant of the amount when it is determined. Landlord may
commingle any payments made with respect to Operating Cost Share Rent or Tax
Share Rent, without payment of interest.

     3.   PREPARATION AND CONDITION OF PREMISES; TENANT'S POSSESSION.

          A.   CONDITION OF PREMISES. Except to the extent of any Tenant
Improvements item on the Schedule, Landlord is leasing the Premises to Tenant
"as is" with the existing paint and carpet, without any obligation to alter,
remodel, improve, repair or decorate any part of the Premises.

          B.   TENANT'S POSSESSION. Tenant's taking possession of any portion of
the Premises (including during the Early Occupancy Period) shall be conclusive
evidence that the Premises was in good order, repair and condition. Throughout
the Term, Tenant shall maintain the


                                          8

<PAGE>

Premises in their condition as of the Completion Date, loss or damage caused by
the elements, ordinary wear, and fire and other casualty excepted, and at the
termination of this Lease, or Tenant's right to possession, Tenant shall return
the Premises to Landlord in the condition required under Section 14 below. To
the extent Tenant falls to perform either obligation, Landlord may, but need
not, restore the Premises to such condition and Tenant shall pay the cost
thereof.

     4.   PROJECT SERVICES.

     Landlord shall furnish services as follows:

          A.   HEATING AND AIR CONDITIONING. During the normal business hours of
8:00 a.m. to 6:00 p.m., Monday through Friday, and 8:00 a.m. to 1:00 p.m. on
Saturday, Landlord shall furnish heating and air conditioning to provide a
comfortable temperature, in Landlord's judgment, for normal business operations,
except to the extent Tenant installs equipment which adversely affects the
temperature maintained by the air conditioning system. If Tenant installs such
equipment, Landlord may install supplementary air conditioning units in the
Premises, and Tenant shall pay to Landlord upon demand as Additional Rent the
cost of installation, operation and maintenance thereof.

     Landlord shall furnish heating and air conditioning after business hours if
Tenant provides Landlord reasonable prior notice, and pays Landlord all the then
current charges for such additional heating or air conditioning.

          B.   ELEVATORS. If the Building is equipped with one or more
elevators, Landlord shall provide passenger elevator service during normal
business hours to Tenant in common with Landlord and all other tenants. Landlord
shall provide limited passenger service at other times, except in case of an
emergency. If applicable, Landlord shall provide freight elevator service at
reasonable hours at Tenant's request, subject to scheduling by the Landlord and
payment for the service by Tenant.

          C.   ELECTRICITY. Landlord shall provide sufficient electricity to
operate normal office lighting and office equipment. Tenant shall not install or
operate in the Premises any electrically operated equipment or other machinery,
other than business machines and equipment normally employed for general office
use which do not require high electricity consumption for operation, without
obtaining the prior written consent of Landlord. If any or all of Tenant's
equipment requires electricity consumption in excess of that which is necessary
to operate normal office equipment, such consumption (including consumption for
computer or telephone rooms and special HVAC equipment) shall be submetered by
Landlord at Tenant's expense, and Tenant shall reimburse Landlord as Additional
Rent for the cost of its submetered consumption based upon Landlord's average
cost of electricity. Such Additional Rent shall be in addition to Tenant's
obligations pursuant to Section 2A(2) to pay its Proportionate Share of
Operating Costs.

          D.   WATER. Landlord shall furnish hot and cold tap water for drinking
and toilet purposes. Tenant shall pay Landlord for water furnished for any other
purpose as Additional Rent at rates fixed by Landlord. Such Additional Rent
shall be in addition to Tenant's obligations pursuant to Section 2A(2) to pay
its Proportionate Share of Operating Costs. Tenant shall not permit water to be
wasted.


                                          9

<PAGE>

          E.   JANITORIAL SERVICE. Landlord shall furnish janitorial service
Monday through Friday as generally provided to other tenants in the Project.
With reasonable prior notice from Tenant, Landlord shall also provide additional
janitorial service on weekends or holidays at Tenant's expense, and Tenant shall
reimburse Landlord as Additional Rent for the cost of such additional janitorial
services. Such Additional Rent shall be in addition to Tenant's obligations
pursuant to Section 2A(2) to pay its Proportionate Share of Operating Costs.

          F.   INTERRUPTION OF SERVICES. If any of the Building equipment or
machinery ceases to function properly for any cause Landlord shall use
reasonable diligence to repair the same promptly. Landlord's inability to
furnish, to any extent, the Project services set forth in this Section 4, or any
cessation thereof resulting from any causes, including any entry for repairs
pursuant to this Lease, and any renovation, redecoration or rehabilitation of
any area of the Building shall not render Landlord liable for damages to either
person or property or for interruption or loss to Tenant's business, nor be
construed as an eviction of Tenant, nor work an abatement of any portion of
Rent, nor relieve Tenant from fulfillment of any covenant or agreement hereof.

     5.   ALTERATIONS AND REPAIRS.

          A.   LANDLORD'S CONSENT AND CONDITIONS. Tenant shall not make any
improvements or alterations to the Premises (the "WORK") without in each
instance submitting plans and specifications for the Work to Landlord and
obtaining Landlord's prior written consent. Tenant shall pay Landlord's standard
charge (or, if Landlord does not have a standard charge, then Landlord's actual
costs incurred) for review of all of the plans and all other items submitted by
Tenant. Landlord will be deemed to be acting reasonably in withholding its
consent for any Work which (a) impacts the base structural components or systems
of the Building, (b) impacts any other tenant's premises, or (c) is visible from
outside the Premises.
     Tenant shall pay for the cost of all Work, including the cost of any and
all approvals, permits, fees and other charges which may be required as a
condition of performing such Work. Upon completion, all Work shall become the
property of Landlord, except for Tenant's trade fixtures and for items which
Landlord requires Tenant to remove at Tenant's cost at the termination of the
Lease pursuant to Section 5E.

     The following requirements shall apply to all Work:

               (1)    Prior to commencement, Tenant shall furnish to Landlord
building permits, certificates of insurance satisfactory to Landlord, and, at
Landlord's request, security for payment of all costs.

               (2)    Tenant shall perform all Work so as to maintain peace and
harmony among other contractors serving the Project and shall avoid interference
with other work to be performed or services to be rendered in the Project.

               (3)    The Work shall be performed in a good and workmanlike
manner, meeting the standard for construction and quality of materials in the
Building, and shall comply with all insurance requirements and all applicable
governmental laws, ordinances and regulations ("GOVERNMENTAL REQUIREMENTS").


                                          10

<PAGE>

               (4)    Tenant shall perform all Work so as to minimize or
prevent disruption to other tenants, and Tenant shall comply with all reasonable
requests of Landlord in response to complaints from other tenants.

               (5)    Tenant shall perform all Work in compliance any
"Policies, Rules and Procedures for Construction Projects" which may be in
effect at the time the Work is performed.

               (6)    Tenant shall permit Landlord to supervise all Work.
Landlord may charge a supervisory fee not to exceed fifteen percent (15%) of
labor, material, and all other costs of the Work, if Landlord's employees or
contractors perform the Work.

               (7)    Upon completion, Tenant shall furnish Landlord With
contractor's affidavits and full and final statutory waivers of liens, as-built
plans and specifications, and receipted bills covering all labor and materials,
and all other close-out documentation related to the Work, including any other
information required under any "Policies, Rules and Procedures for Construction
Projects" which may be in effect at the time.

          B.   REPAIRS. If any part of the mechanical, electrical or other
systems in the Premises (e.g., HVAC, life safety or fire extinguisher/sprinkler
system) shall be damaged, Tenant shall promptly notify Landlord, and Landlord
shall repair such damage. Landlord may also at any reasonable time make any
repairs or alterations which Landlord deems necessary for the safety or
protection of the Project, or which Landlord is required to make by any court or
pursuant to any Governmental Requirement. Tenant shall at its expense make all
other repairs necessary to keep the Premises, and Tenant's fixtures and personal
property, in good order, condition and repair in compliance with all applicable
Governmental Requirements; to the extent Tenant falls to do so, Landlord may
make such repairs itself. The cost of any repairs made by Landlord on account of
Tenant's default, or on account of the mis-use or neglect by Tenant or its
invitees, contractors or agents anywhere in the Project, shall become Additional
Rent payable by Tenant on demand. It is a condition precedent to all Landlord's
obligations to repair and maintain that Tenant shall have notified Landlord of
the need of such repairs or maintenance. Tenant waives the provisions of
Sections 1941 and 1942 of the California Civil Code and any similar or successor
law regarding Tenant's right to make repairs and deduct the cost of such repairs
from the Rent due under this Lease.

          C.   NO LIENS. Tenant has no authority to cause or permit any lien or
encumbrance of any kind to affect Landlord's interest in the Project; any such
lien or encumbrance shall attach to Tenant's interest only. If any mechanic's
lien shall be filed or claim of lien made for work or materials furnished to
Tenant, then Tenant shall at its expense within ten (10) days thereafter either
discharge or contest the lien or claim. If Tenant contests the lien or claim,
then Tenant shall (i) within such ten (10) day period, provide Landlord adequate
security for the lien or claim, (ii) contest the lien or claim in good faith by
appropriate proceedings that operate to stay its enforcement, and (iii) pay
promptly any final adverse judgment entered in any such proceeding. If Tenant
does not comply with these requirements, Landlord may discharge the lien or
claim, and the amount paid, as well as attorney's fees and other expenses
incurred by Landlord, shall become Additional Rent payable by Tenant on demand.


                                          11

<PAGE>

          D.   OWNERSHIP OF IMPROVEMENTS. All Work as defined in this Section 5,
partitions, hardware, equipment, machinery and all other improvements and all
fixtures except trade fixtures, constructed in the Premises by either Landlord
or Tenant, (i) shall become Landlord's property upon installation without
compensation to Tenant, unless Landlord consents otherwise in writing, and
(ii) shall at Landlord's option either (a) be surrendered to Landlord with the
Premises at the termination of the Lease or of Tenant's right to possession, or
(b) be removed in accordance with Subsection 5E below (unless Landlord at the
time it gives its consent to the performance of such construction expressly
waives in writing the right to require such removal).

          E.   REMOVAL UPON TERMINATION. Upon the termination of this Lease or
Tenant's right of possession Tenant shall remove from the Premises and Project
its trade fixtures, furniture, moveable equipment and other personal property,
any improvements which Landlord elects pursuant to Section 5D shall be removed
by Tenant, and any improvements to any portion of the Project other than the
Premises. If Tenant does not timely remove such property, then Tenant shall be
conclusively presumed to have, at Landlord's election (i) conveyed such property
to Landlord without compensation or (ii) abandoned such property, and Landlord
may dispose of or store any part thereof in any manner at Tenant's sole cost,
without waiving Landlord's right to claim from Tenant all expenses arising out
of Tenant's failure to remove the property, and without liability to Tenant or
any other person. Landlord shall have no duty to be a bailee of any such
personal property. If Landlord elects abandonment, Tenant shall pay to Landlord,
upon demand, any expenses incurred for disposition.

     6.   USE OF PREMISES.

          A.   LIMITATION ON USE. Tenant shall use the Premises only for the
Permitted Use stated in the Schedule. Tenant shall not allow any use of the
Premises which will negatively affect the cost of coverage of Landlord's
insurance on the Project. Tenant shall not allow any inflammable or explosive
liquids or materials to be kept on the Premises. Tenant shall not allow any use
of the Premises which would cause the value or utility of any part of the
Premises to diminish or would interfere with any other tenant or with the
operation of the Project by Landlord. Tenant shall not permit any nuisance or
waste upon the Project, or allow any offensive noise or odor in or around the
Project. At the end of each business day, or more frequently if necessary,
Tenant shall deposit all garbage and other trash (excluding any inflammable,
explosive and/or hazardous materials) in trash bins or containers approved by
Landlord in locations designated by Landlord from time to time. If any
governmental authority shall deem the Premises to be a "place of public
accommodation" under the Americans with Disabilities Act or any other comparable
law as a result of Tenant's use, Tenant shall either modify its use to cause
such authority to rescind its designation or be responsible for any alterations,
structural or otherwise, required to be made to the Building or the Premises
under such laws.

          B.   SIGNS. Tenant shall not place on any portion of the Premises any
sign, placard, lettering, banner, displays or other advertising or communicative
material which is visible from the exterior of the Building without the prior
written approval of Landlord. Any approved signs shall strictly conform to all
Governmental Restrictions, any CC&R's recorded against the Project, and
Landlord's Signage Standards in effect at the time, and shall be installed (and
removed upon the


                                          12

<PAGE>

Termination Date) at Tenant's expense. Tenant, at its sole cost and expense,
shall maintain such signs in good condition and repair, including the repair of
any damage caused to the Building and/or Project upon the removal of such signs.
Landlord current Signage Standards are attached hereto as EXHIBIT C. Landlord
shall install the Building standard sign containing Tenant's name at the
entrance to the Premises and include Tenant's name in the tenant directory
located in the lobby in the first floor of the Building.

          C.   PARKING. Tenant shall have the right to park in the Project's
parking facilities in common with other tenants of the Project upon terms and
conditions, as may from time to time be established by Landlord. Tenant agrees
not to overburden the parking facilities (i.e., use more than the number of
parking stalls indicated on the Schedule) and agrees to cooperate with Landlord
and other tenants in the Project in the use of the parking facilities. Landlord
reserves the right in its discretion to determine whether the parking facilities
are becoming crowded and to allocate and assign parking spaces among Tenant and
the other tenants in the Project. Landlord shall not be liable to Tenant, nor
shall this Lease be affected, if any parking is impaired by moratorium,
initiative, referendum, law, ordinance, regulation or order passed, issued or
made by any governmental or quasi-governmental body.

          D.   PROHIBITION AGAINST USE OF ROOF AND STRUCTURE OF BUILDING.
Tenant shall be prohibited from using any all or any portion of the roof of the
Building or any portion of the structure of the Building during the Term of
this Lease (or any extensions thereof) for any purposes (including without
limitation for the installation, maintenance and repair of a satellite dish
and/or other telecommunications equipment), without the prior written consent of
Landlord, which consent Landlord may withhold in its sole and absolute
discretion. Any use of the roof or the structure of the Building for satellite
dish or antennae purposes shall be pursuant to the terms of a separate license
agreement and not this Lease. Nothing herein shall limit or restrict Landlord's
rights under Section 11.N, or require Landlord to obtain Tenant's consent prior
to exercising such rights.

     7.   GOVERNMENTAL REQUIREMENTS AND BUILDING RULES. Tenant shall comply with
all Governmental Requirements applying to its use, repair and maintenance of the
Premises. Tenant shall also comply with all reasonable rules for the Project
which may be established and amended from time to time by Landlord. The present
rules and regulations are contained in Exhibit B. Failure by another tenant to
comply with the rules or failure by Landlord to enforce them shall not relieve
Tenant of its obligation to comply with the rules or make Landlord responsible
to Tenant in any way. Landlord shall use reasonable efforts to apply the rules
and regulations uniformly with respect to Tenant and any other tenants in the
Project under leases containing rules and regulations similar to this Lease. In
the event of alterations and repairs performed by Tenant, Tenant shall comply
with the provisions of Section 5 of this Lease and also any applicable
"Policies, Rules and Regulations for Construction Projects" which may be
established and in effect at the time.

     8.   WAIVER OF CLAIMS; INDEMNIFICATION; INSURANCE.

          A.   WAIVER OF CLAIMS. To the extent permitted by law, Tenant waives
any claims it may have against Landlord or its officers, directors, employees or
agents for business interruption or damage to property sustained by Tenant as
the result of any act or omission of Landlord, its agents or employees. To the
extent permitted by law, Landlord waives any claims it may have against


                                          13

Landlord and its officers, directors, employees and agents against any claim by
any third party for injury to any person or damage to or loss of any property

invitees, or Tenant's breach of its obligations under this Lease. Tenant's
obligations under this Section shall survive the termination of this Lease.

     Landlord shall indemnify, defend and hold harmless Tenant and its officers,
directors, employees and agents against any claim by any third party for injury
or damage to person or the Premises to the extent caused by the gross negligence
or intentional misconduct of Landlord or any of Landlord's employees or agents,

under this section shall survive the termination of this Lease.

          D.   INSURANCE CERTIFICATES. Tenant shall deliver to Landlord
certificates evidencing all required insurance no later than five (5) days prior
to the Commencement Date and each renewal date. Each certificate will provide
for thirty (30) days prior written notice of cancellation to Landlord and

to property insurance, Landlord and Tenant mutually waive all rights of
subrogation, and the respective "All-Risk" coverage property insurance policies
carried by Landlord and Tenant shall contain enforceable waiver of subrogation
endorsements.

     9.   FIRE AND OTHER CASUALTY.

          A.   TERMINATION. If a fire or other casualty causes substantial
damage to the Building or the Premises, and sufficient insurance proceeds will
be available to Landlord to cover the cost of any restoration to the Building
and Premises, Landlord shall engage a registered architect to


                                          15

<PAGE>

certify within one (1) month of the casualty to both Landlord and Tenant the
amount of time needed to restore the Building and the Premises to tenantability,
using standard working methods without the payment of overtime and other
premiums. If the time needed exceeds twelve (12) months from the beginning of
the restoration, or two (2) months therefrom if the restoration would begin
during the last twelve (12) months of the Lease, then in the case of the
Premises, either Landlord or Tenant may terminate this Lease, and in the case of
the Building, Landlord may terminate this Lease, by notice to the other party
within ten (10) days after the notifying party's receipt of the architect's
certificate. If sufficient insurance proceeds will not be available to Landlord
to cover the cost of any restoration to the Building or the Premises, Landlord
may terminate this Lease by written notice to Tenant. Any termination pursuant
to this Section 9A shall be effective thirty (30) days from the date of such
termination notice and Rent shall be paid by Tenant to that date, with an
abatement for any portion of the space which has been untenantable after the
casualty.

          B.   RESTORATION. If a casualty causes damage to the Building or 
the Premises but this Lease is not terminated for any reason, then subject to 
the rights of any mortgagees or ground lessors, Landlord shall obtain the 
applicable insurance proceeds and diligently restore the Building and the 
Premises subject to current Governmental Requirements. Landlord's obligation, 
should it elect or be obligated to repair or rebuild, shall be limited to the 
basic Premises, the building-standard Tenant Improvements, or the basic 
Building, as the case may be, and Tenant shall, at Tenant's expense, replace 
or fully repair its damaged improvements (including any Tenant Improvements 
in excess of the building standard), personal property and fixtures. Rent 
shall be abated on a per diem basis during the restoration for any portion of 
the Premises which is untenantable, except to the extent that the casualty 
was caused by the negligence or intentional misconduct of Tenant, its agents 
or employees. Tenant shall not be entitled to any compensation or damages 
from Landlord for loss of the use of the Premises, damage to Tenant's 
personal property and trade fixtures or any inconvenience occasioned by such 
damage, repair or restoration. Tenant hereby waives the provisions of Section 
1932, Subdivision 2, and Section 1933, Subdivision 4, of the California Civil 
Code, and the provisions of any similar law hereinafter enacted.

     10.  EMINENT DOMAIN. If a part of the Project is taken by eminent domain or
deed in lieu thereof which is so substantial that the Premises cannot reasonably
be used by Tenant for the operation of its business, then either party may
terminate this Lease effective as of the date of the taking. If any substantial
portion of the Project is taken without affecting the Premises, then Landlord
may terminate this Lease as of the date of such taking. Rent shall abate from
the date of the taking in proportion to any part of the Premises taken. The
entire award for a taking of any kind shall be paid to Landlord, and Tenant
shall have no right to share in the award; provided, however, that nothing
contained herein shall be deemed to give Landlord any interest in or require
Tenant to assign to Landlord any separate award made to Tenant for the taking of
Tenant's personal property and trade fixtures, or its relocation costs. All
obligations accrued to the date of the taking shall be performed by each party.

     11.  RIGHTS RESERVED TO LANDLORD.

     Landlord may exercise at any time any of the following rights respecting
the operation of the Project without liability to the Tenant of any kind:


                                          16

          C.   WINDOW TREATMENTS. To approve, at its discretion, prior to

have the right to immediate access) to inspect the Premises, and to perform its

                                          18

<PAGE>

          D.   CREDIT DEFAULT. One of the following credit defaults occurs:

debts, or makes a general assignment for the benefit of creditors;

               (3)    Any third party obtains a levy or attachment under
process of law against Tenant's leasehold interest.

          E.   VACATION OR ABANDONMENT DEFAULT. Tenant vacates or abandons the

     13.  LANDLORD REMEDIES. Upon a default, Landlord shall have the following
remedies, in addition to all other rights and remedies provided by law or
otherwise provided in this Lease, to which Landlord may resort cumulatively or
in the alternative:

          A.   Landlord may continue this Lease in full force and effect, and
this Lease shall continue in full force and effect as long as Landlord does not
terminate this Lease, and Landlord shall have the right to collect Rent when
due.

          B.   Landlord may enter the Premises and release them to third parties
for Tenant's account for any period, whether shorter or longer than the
remaining Term. Tenant shall be liable immediately to Landlord for all costs
Landlord incurs in reletting the Premises or any part thereof, including,
without limitation, broker's commissions, expenses of cleaning and redecorating
the Premises required by the reletting and like costs. Tenant shall pay to
Landlord the Rent and other sums due under this Lease on the date the Rent is
due, less the rent and other sums received by Landlord from any releasing. No
act by Landlord other than giving written notice to Tenant shall terminate this
Lease. Acts of maintenance, efforts to relet the Premises or the appointment of
a receiver on Landlord's initiative to protect Landlord's interest under this
Lease shall not constitute a termination of Tenant's right to possession.

          C.   Landlord may terminate this Lease by giving Tenant written notice
of termination, in which event this Lease shall terminate on the date for
termination set forth in such notice. Tenant shall immediately vacate the
Premises and deliver possession to Landlord, and Landlord may repossess the
Premises and may, at Tenant's sole cost, remove any of Tenant's signs and any of
its other property, without relinquishing its right to receive Rent or any other
right against Tenant. On termination, Landlord has the right to recover from
Tenant as damages:

               (1)    The worth at the time of award of unpaid Rent and other
sums due and payable which had been earned at the time of termination; plus


                                          19

<PAGE>

               (2)    The worth at the time of award of the amount by which the
unpaid Rent and other sums due and payable which after termination until the
time of award exceeds the amount of such Rent loss that Tenant proves could have
been reasonably avoided; plus

               (3)    The worth at the time of award of the amount by which the
unpaid Rent and other sums due and payable for the balance of the Term after the
time of award exceeds the amount of such Rent loss that Tenant proves could be
reasonably avoided; plus

               (4)    Any other amount necessary to compensate Landlord for all
the detriment proximately caused by Tenant's failure to perform Tenant's
obligations under this Lease, or which, in the ordinary course of things, would
be likely to result therefrom, including, without limitation, any costs or
expenses incurred by Landlord: (i) in retaking possession of the Premises;
(ii) in maintaining, repairing, preserving, restoring, replacing, cleaning,
altering or rehabilitating the Premises or any portion thereof, including such
acts for reletting to a new tenant or tenants; (iii) for leasing commissions; or
(iv) for any other costs necessary or appropriate to relet the Premises; plus

               (5)    At Landlord's election, such other amounts in addition to
or in lieu of the foregoing as may be permitted from time to time by the laws of
the State of California.

     The "worth at the time of award" of the amounts referred to in Sections
13C(1) and 13C(2) is computed by allowing interest at the maximum rate permitted
by law on the unpaid rent and other sums due and payable from the termination
date through the date of award. The "worth at the time of award" of the amount
referred to in Section 13C(3) is 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%). Tenant waives redemption or relief from forfeiture under
California Code of Civil Procedure Sections 1174 and 1179, or under any other
present or future law, in the event Tenant is evicted or Landlord takes
possession of the Premises by reason of any default of Tenant hereunder.

          D.   LANDLORD'S REMEDIES CUMULATIVE. All of Landlord's remedies under
this Lease shall be in addition to all other remedies Landlord may have at law
or in equity. Waiver by Landlord of any breach of any obligation by Tenant shall
be effective only if it is in writing, and shall not be deemed a waiver of any
other breach, or any subsequent breach of the same obligation. Landlord's
acceptance of payment by Tenant shall not constitute a waiver of any breach by
Tenant, and if the acceptance occurs after Landlord's notice to Tenant, or
termination of the Lease or of Tenant's right to possession, the acceptance
shall not affect such notice or termination. Acceptance of payment by Landlord
after commencement of a legal proceeding or final judgment shall not affect such
proceeding or judgment. Landlord may advance such monies and take such other
actions for Tenant's account as reasonably may be required to cure or mitigate
any default by Tenant. Tenant shall immediately reimburse Landlord for any such
advance, and such sums shall bear interest at the default interest rate until
paid.

          E.   WAIVER OF TRIAL BY JURY. EACH PARTY WAIVES TRIAL BY JURY IN THE
EVENT OF ANY LEGAL PROCEEDING BROUGHT BY THE OTHER IN CONNECTION WITH THIS
LEASE. EACH PARTY SHALL BRING ANY ACTION AGAINST THE OTHER IN CONNECTION WITH
THIS LEASE IN A FEDERAL OR


                                          20

<PAGE>

STATE COURT LOCATED IN CALIFORNIA, CONSENTS TO THE JURISDICTION OF SUCH COURTS,
AND WAIVES ANY RIGHT TO HAVE ANY PROCEEDING TRANSFERRED FROM SUCH COURTS ON THE
GROUND OF IMPROPER VENUE OR INCONVENIENT FORUM.

          F.   LITIGATION COSTS. Tenant shall pay Landlord's reasonable
attorneys' fees and other costs in enforcing this Lease, whether or not suit is
filed.

     14.  SURRENDER. Upon the expiration or earlier termination of this Lease
for any reason, Tenant shall surrender the Premises to Landlord in its condition
existing as of the Commencement Date, normal wear and tear and damage by fire or
other casualty excepted, with all interior walls repaired and repainted if
marked or damaged, all carpets broom cleaned, all broken, marred or
nonconforming acoustical ceiling tiles replaced, all windows washed, the
plumbing and electrical systems and lighting in good order and repair, including
replacement of any burned out or broken light bulb or ballasts, and all floors
broom cleaned, all to the reasonable satisfaction of Landlord. Tenant shall
remove from the Premises all Tenant's personal property and all of Tenant's
alterations required to be removed pursuant to Section 5E, and restore the
Premises to its condition prior to their installation. If Tenant fails to remove
any alterations and/or Tenant's personal property, and such failure continues
after the termination of this Lease, Landlord may retain or dispose of such
property and all rights of Tenant with respect to it shall cease, or Landlord
may place all or any portion of such property in public storage for Tenant's
account. Tenant shall be liable to Landlord for costs of removal of any such
alterations and Tenant's personal property and storage and transportation costs
of same, and the cost of repairing and restoring the Premises, together with
interest at the Interest Rate from the date of expenditure by Landlord. If the
Premises are not so surrendered at the termination of this Lease, Tenant shall
indemnify Landlord against all loss or liability, including attorneys' fees and
costs, resulting from delay by Tenant in so surrendering the Premises.

     15.  HOLDOVER. Tenant shall have no right to holdover possession of the
Premises after the expiration or termination of this Lease without Landlord's
prior written consent which Landlord may withhold in its sole and absolute
discretion. If, however, Tenant retains possession of any part of the Premises
after the Term, Tenant shall become a month-to-month tenant for the entire
Premises upon all of the terms of this Lease as might be applicable to such
month-to-month tenancy, except that Tenant shall pay all of the Base Rent,
Operating Cost Share Rent and Tax Share Rent at double the rate in effect
immediately prior to such holdover, computed on a monthly basis for each full or
partial month Tenant remains in possession. Tenant shall also pay Landlord all
of Landlord's direct and consequential damages resulting from Tenant's holdover.
No acceptance of Rent or other payments by Landlord under these holdover
provisions shall operate as a waiver of Landlord's right to regain possession or
any other of Landlord's remedies.

          A.   SUBORDINATION. This Lease shall be subordinate to any present or
future ground lease or mortgage respecting the Project, and any amendments to
such ground lease or mortgage, at the election of the ground lessor or mortgagee
as the case may be, effected by notice to Tenant in the manner provided in this
Lease. The subordination shall be effective upon such notice, but at the request
of Landlord or ground lessor or mortgagee, Tenant shall within ten (10) days of
the request, execute and deliver to the requesting party any reasonable
documents provided to evidence the subordination.

          B.   TERMINATION OF GROUND LEASE OR FORECLOSURE OF MORTGAGE. If any 
ground lease is terminated or mortgage foreclosed or deed in lieu of 
foreclosure given and the ground lessor, mortgagee, or purchaser at a 
foreclosure sale shall thereby become the owner of the Project, Tenant shall 
attorn to such ground lessor or mortgagee or purchaser without any deduction 
or setoff by Tenant, and this Lease shall continue in effect as a direct 
lease between Tenant and such ground lessor, mortgagee or purchaser. The 
ground lessor or mortgagee or purchaser shall be liable as Landlord only 
during the time such ground lessor or mortgagee or purchaser is the owner of 
the Project. At the request of Landlord, ground lessor or mortgagee, Tenant 
shall execute and deliver within ten (10) days of the request any document 
furnished by the requesting party to evidence Tenant's agreement to attorn.

          C.   SECURITY DEPOSIT. Any ground lessor or mortgagee shall be
responsible for the return of any security deposit by Tenant only to the extent
the security deposit, if any, is received by such ground lessor or mortgagee.

          D.   NOTICE AND RIGHT TO CURE. The Project is subject to any ground
lease and mortgage identified with name and address of ground lessor or
mortgagee in Exhibit D to this Lease (as the same may be amended from time to
time by written notice to Tenant). Tenant agrees to send by registered or
certified mail to any ground lessor or mortgagee identified either in such
Exhibit or in any later notice from Landlord to Tenant a copy of any notice of
default sent by Tenant to Landlord. If Landlord fails to cure such default
within the required time period under this Lease, but ground lessor or mortgagee
begins to cure within ten (10) days after such period and proceeds diligently to
complete such cure, then ground lessor or mortgagee shall have such additional
time as is necessary to complete such cure, including any time necessary to
obtain possession if possession is necessary to cure, and Tenant shall not begin
to enforce its remedies so long as the cure is being diligently pursued.

          E.   DEFINITIONS. As used in this Section 16, "mortgage" shall include
"trust deed" and "deed of trust", "mortgagee" shall include "trustee",
"beneficiary" and the mortgagee of any ground lessee, and "ground lessor",
"mortgagee", and "purchaser at a foreclosure sale" shall include, in each case,
all of its successors and assigns, however remote.

     17.  ASSIGNMENT AND SUBLEASE.

          A.   IN GENERAL. Tenant shall not, without the prior consent of
Landlord in each case, (i) make or allow any assignment or transfer, by
operation of law or otherwise, of any part of


                                          22

<PAGE>

Tenant's interest in this Lease, (ii) grant or allow any lien or encumbrance, by
operation of law or otherwise, upon any part of Tenant's interest in this Lease,
(iii) sublet any part of the Premises, or (iv) permit anyone other than Tenant
and its employees to occupy any part of the Premises. Tenant shall remain
primarily liable for all of its obligations under this Lease, notwithstanding
any assignment or transfer. No consent granted by Landlord shall be deemed to be
a consent to any subsequent assignment or transfer, lien or encumbrance,
sublease or occupancy. Tenant shall pay all of Landlord's attorneys' fees and
other expenses incurred in connection with any consent requested by Tenant or in
reviewing any proposed assignment or subletting. Any assignment or transfer,
grant of lien or encumbrance, or sublease or occupancy without Landlord's prior
written consent shall be void. If Tenant shall assign this Lease or sublet the
Premises in its entirety any rights of Tenant to renew this Lease, extend the
Term or to lease additional space in the Project shall be extinguished thereby
and will not be transferred to the assignee or subtenant, all such rights being
personal to the Tenant named herein.

          B.   LANDLORD'S CONSENT. Landlord will not unreasonably withhold its
consent to any proposed assignment or subletting. It shall be reasonable for
Landlord to withhold its consent to any assignment or sublease if (i) Tenant is
in default under this Lease, (ii) the proposed assignee or sublessee is a tenant
in the Project or an affiliate of such a tenant or a party that Landlord has
identified as a prospective tenant in the Project, (iii) the financial
responsibility, nature of business, and character of the proposed assignee or
subtenant are not all reasonably satisfactory to Landlord, (iv) in the
reasonable judgment of Landlord the purpose for which the assignee or subtenant
intends to use the Premises (or a portion thereof) is not in keeping with
Landlord's standards for the Building or are in violation of the terms of this
Lease or any other leases in the Project, (v) the proposed assignee or subtenant
is a government entity, or (vi) the proposed sublease is for less than the
entire Premises or for less than the remaining Term of the Lease. The foregoing
shall not exclude any other reasonable basis for Landlord to withhold its
consent.

          C.   PROCEDURE. Tenant shall notify Landlord of any proposed 
assignment or sublease at least thirty (30) days prior to its proposed 
effective date. The notice shall include the name and address of the proposed 
assignee or subtenant, its corporate affiliates in the case of a corporation 
and its partners in a case of a partnership, an execution copy of the 
proposed assignment or sublease, and sufficient information to permit 
Landlord to determine the financial responsibility and character of the 
proposed assignee or subtenant. As a condition to any effective assignment of 
this Lease, the assignee shall execute and deliver in form satisfactory to 
Landlord at least fifteen (15) days prior to the effective date of the 
assignment, an assumption of all of the obligations of Tenant under this 
Lease. As a condition to any effective sublease, subtenant shall execute and 
deliver in form satisfactory to Landlord at least fifteen (15) days prior to 
the effective date of the sublease, an agreement to comply with all of 
Tenant's obligations under this Lease, and at Landlord's option, an agreement 
(except for the economic obligations which subtenant will undertake directly 
to Tenant) to attorn to Landlord under the terms of the sublease in the event 
this Lease terminates before the sublease expires.

          D.   CHANGE OF MANAGEMENT OR OWNERSHIP. Any transfer of the direct or
indirect power to affect the management or policies of Tenant or direct or
indirect change in 25% or more of the ownership interest in Tenant shall
constitute an assignment of this Lease.


                                          23

<PAGE>

          E.   EXCESS PAYMENTS. If Tenant shall assign this Lease or sublet any
part of the Premises for consideration in excess of the pro-rata portion of Rent
applicable to the space subject to the assignment or sublet, then Tenant shall
pay to Landlord as Additional Rent 75% of any such excess immediately upon
receipt.

          F.   RECAPTURE. Landlord may, by giving written notice to Tenant
within thirty (30) days after receipt of Tenant's notice of assignment or
subletting, terminate this Lease with respect to the space described in Tenant's
notice, as of the effective date of the proposed assignment or sublease and all
obligations under this Lease as to such space shall expire except as to any
obligations that expressly survive any termination of this Lease.

     18.  CONVEYANCE BY LANDLORD. If Landlord shall at any time transfer its
interest in the Project or this Lease, Landlord shall be released of any
obligations occurring after such transfer, except the obligation to return to
Tenant any security deposit not delivered to its transferee, and Tenant shall
look solely to Landlord's successors for performance of such obligations. This
Lease shall not be affected by any such transfer.

     19.  ESTOPPEL CERTIFICATE. Each party shall, within ten (10) days of
receiving a request from the other party, execute, acknowledge in recordable
form, and deliver to the other party or its designee a certificate stating,
subject to a specific statement of any applicable exceptions, that the Lease as
amended to date is in full force and effect, that the Tenant is paying Rent and
other charges on a current basis, and that to the best of the knowledge of the
certifying party, the other party has committed no uncured defaults and has no
offsets or claims. The certifying party may also be required to state the date
of commencement of payment of Rent, the Commencement Date, the Termination Date,
the Base Rent, the current Operating Cost Share Rent and Tax Share Rent
estimates, the status of any improvements required to be completed by Landlord,
the amount of any security deposit, and such other matters as may be reasonably
requested. Failure to deliver such statement within the time required shall be
conclusive evidence against the non-certifying party that this Lease, with any
amendments identified by the requesting party, is in full force and effect, that
there are no uncured defaults by the requesting party, that not more than one
month's Rent has been paid in advance, that the non-certifying party has not
paid any security deposit, and that the non-certifying party has no claims or
offsets against the requesting party.

     20.  LEASE DEPOSIT. Tenant shall deposit with Landlord on the date Tenant
executes and delivers this Lease to Lease the cash sums set forth in the
Schedule for both Prepaid Rent and Security Deposit (collectively, the "LEASE
DEPOSIT"). The Prepaid Rent shall be applied by Landlord against the first full
month's Base Rent payment obligation hereunder. The Security Deposit shall be
held by Landlord as security for the performance of all of its obligations in
the amount set forth on the Schedule. If Tenant defaults under this Lease,
Landlord may apply all or any part of the Security Deposit for the payment of
any Rent or other sum in default, the repair of any damage to the Premises
caused by Tenant or the payment of any other amount which Landlord may spend or
become obligated to spend by reason of Tenant's default or to compensate
Landlord for any other loss or damage which Landlord may suffer by reason of
Tenant's default to the full extent permitted by law. Tenant hereby waives any
restriction on the use or application of the Security Deposit by Landlord as set
forth in California Civil Code Section 1950.7. To the extent any portion of the
Security Deposit is used, Tenant shall within five (5) days after demand from
Landlord restore the


                                          24

<PAGE>

deposit to its full amount. Landlord may keep the Security Deposit in its
general funds and shall not be required to pay interest to Tenant on the deposit
amount. If Tenant shall perform all of its obligations under this Lease and
return the Premises to Landlord at the end of the Term, Landlord shall return
all of the remaining Security Deposit to Tenant within thirty (30) days after
the end of the Term. The Security Deposit shall not serve as an advance payment
of Rent or a measure of Landlord's damages for any default under this Lease.

     If Landlord transfers its interest in the Project or this Lease, Landlord
may transfer the Security Deposit to its transferee. Upon such transfer,
Landlord shall have no further obligation to return the Security Deposit to
Tenant, and Tenant's right to the return of the Security Deposit shall apply
solely against Landlord's transferee.

     21.  FORCE MAJEURE. Landlord shall not be in default under this Lease to
the extent Landlord is unable to perform any of its obligations on account of
any strike or labor problem, materials, supplies or energy shortage,
governmental pre-emption or prescription, national emergency, or any other cause
of any kind beyond the reasonable control of Landlord ("FORCE MAJEURE").

     22.  TENANT'S PERSONAL PROPERTY AND FIXTURES. Tenant hereby grants to
Landlord a security interest in all of its personal property and trade fixtures
now or hereafter located within the Premises as additional security for
performance of all of Tenant's obligations under this Lease. Tenant may replace
such personal property and fixtures with items of equal or better quality, but
shall not otherwise remove them from the Premises without the consent of
Landlord until all of the obligations of Tenant under this Lease have been
performed. This Lease constitutes a security agreement creating a security
interest in such property in favor of Landlord, subject only to the liens of
existing creditors, and Landlord may at any time file this Lease as a financing
statement under the Uniform Commercial Code of the state in which the Project is
located.

     23.  NOTICES. All notices, consents, approvals and similar communications
to be given by one party to the other under this Lease, shall be given in

                                       RECITALS

     A.   Landlord and Tenant entered into that certain Office Lease dated

     Original Lease and the terms of this Amendment, the parties agree that
