Market Overview

     Direct Marketing Services

     Direct marketing enables the delivery of a customized message to a defined
audience and the measurement of the response to that message.  The marketing
program can then be evaluated, refined and continuously improved.  Effective
direct marketing programs require a detailed understanding of customers' and
prospective customers' purchasing patterns to promote more relevant and timely
offers.  The ability to measure the response to a specific marketing program
allows the financial return on marketing expenditures to be analyzed.

     Demographic shifts and lifestyle changes, combined with a proliferation of
new products and services and the evolution of new marketing mediums (including
cable, telemarketing, direct mail, direct response, on-line services and the
Internet) have made marketing campaigns increasingly complex. At the same time,
marketing costs have been subjected to growing scrutiny by marketing managers.
Many marketers have responded to these pressures by reallocating their
expenditures from traditional mass marketing to direct marketing.

     Direct marketing programs depend upon the ability of a marketer to access
information about their customers and prospects.  Historically, valuable sales
and customer data within large corporations was often inaccessible as it
resided in various incompatible systems.  Through advances in computer and
software technology, it is now possible to compile very large databases using
disparate customer record files combined with data collected from compiled lists
owned by third parties.  With the development of relational and multidimensional
databases, marketers can add new categories of data without having to redesign
or rebuild their databases, making it possible to use this data in order to
develop customer profiles based on many different attributes.  Finally, the
development of decision support software has allowed utilization of database
marketing at the decision maker level in a client/server environment.

     Direct marketing service providers require the technical resources to
manage exceptionally large relational and multidimensional databases and the
software capabilities to convert vast amounts of data into usable information.
These functions must be performed within tight time constraints making
processing speed critical.  Many companies choose not to 

                                       2
<PAGE>
 
invest in the technological resources necessary to build these capabilities and
as a result, choose to outsource database management and list processing
services to a proven vendor as a more effective means of accessing the latest
technological resources and expertise.

     Information Technology Outsourcing

     Information technology outsourcing includes the provision and management of
all or a portion of a client's data processing and information systems
functions.  In essence, the information technology outsourcing services vendor
assumes the client's data center functions and the client continues to retain
direct access to their information, although the hardware and software are no
longer located on the client's premises.  Increasingly, companies are
outsourcing their information processing applications as part of an overall
effort to focus internal resources on their core competencies while improving
operating efficiencies and reducing costs.

     Many companies' information technology departments are burdened with
increasing demands for instant access and communication of large amounts of data
to multiple locations in real time, requiring high speed processing and
telecommunications capabilities.  In addition, because computing technology is
evolving rapidly, companies are increasingly faced with the decision to either
continually invest a significant amount of capital in new technology or to
outsource.  The increasing demands on information technology departments coupled
with the significant ongoing investments required to remain technologically
current are key factors in the growing trend towards outsourcing.  The
advantages to organizations of outsourcing their data processing activities
include improved flexibility, reduced capital investments, higher performance
and service levels, improved speed of delivery, capacity on demand and cost
control.

     The Company believes that the market in which it competes is best defined
by the scale of its clients' data processing requirements, not by such clients'
revenues.  Typically, the scale of these requirements is large but not of a size
typically sought by the larger outsourcing service providers such as
International Business Machine Corporation's Global Services division,
Electronic Data Systems Corporation, Computer Sciences Corporation, Perot
Systems, Inc. and SHL Systemhouse, Inc., a subsidiary of MCI Communications
Corporation.  The Company believes that its data center processing capabilities,
while not of a similar scale, are similar to or better than the capabilities of
its large competitors in terms of throughput, turnaround capabilities and state-
of-the-art equipment utilized.

May & Speh Services and Products

     Direct Marketing Services

     May & Speh provides comprehensive direct marketing services, including
database creation, data warehousing, predictive behavioral modeling, list
processing and data enhancement.  Rather than selling standard products and
services to it clients, the Company's approach has been to design and implement
creative custom database solutions around the specific needs of its clients.
The principal advantages of customized services include (i) the ability of the
database to expand and adapt to the client's changing business needs, (ii) the
ability to have these services developed on a platform of the client's choosing,
and (iii) the integration of database services with the list processing services
necessary to keep the database current.

     Database Management Services.  May & Speh's broad range of database
management services begins with the Company's proven approach to database
development which includes planning and analytical processes to determine the
client's needs.  Typically, direct marketing databases originate with the
client's own files, both current and historical, which generally include name,
address and gender, as well as frequency and value of products purchased.

     May & Speh analyzes all of the client's disparate operational files and
determines what data will add value and can be made actionable.  Utilizing both
proprietary and commercial software, the Company consolidates all of the
disparate information and relationships across multiple files and converts the
client's raw information into a clean, consolidated format so that relationships
can be understood at both the customer and household levels.

                                       3
<PAGE>
 
     Once the client's customer data is consolidated and the database created,
May & Speh enhances the data by utilizing a wide selection of demographic,
geographic, census (age, approximate income level, education level and household
composition) and lifestyle information for over 100 million individuals and
households.  May & Speh licenses this information from leading data compilers.
The combination of each client's proprietary customer information with these
external data files provides a complete profile of a client's customers,
enabling the client, through the use of May & Speh's behavior modeling and
analysis services, to act on the data.  Through the development of a scoring
model, the client can segment its database and determine its best customers and
prospects in each marketplace.  The entire process results in a marketing
program that can be targeted to distinct audiences with a high propensity to buy
the client's products.  These databases typically reside at May & Speh's data
center.  Because of the dynamic nature and complexity of these databases, May &
Speh is routinely asked by its clients as part of their ongoing direct marketing
efforts to update the databases with the results of recent marketing programs
and to periodically perform the list processing service described below.

     List Processing Services.  List processing includes the preparation and
generation of comprehensive name and address lists which are used in direct
marketing promotions.  May & Speh's state-of-the-art data center and large
volume processing capabilities allow the Company to meet the direct marketing
needs of its clients, processing over seven billion records through its advanced
list processing software services in fiscal 1997.  May & Speh customizes a list
processing solution by utilizing a variety of commercial and proprietary
software products, such as Address Conversion and Reformat, Address
Standardization and Enhanced Merge/Purge, as well as products which are licensed
through the United States Postal Service such as National Change of Address,
Delivery Sequence File and Locatable Address Conversion System.  Other licensed
products are databases used for suppressions such as the Direct Marketing
Association's Mail Preference File, the American Correctional Association Prison
Suppress File and other files.

     May & Speh's list processing services seek to reduce its clients' mailing
costs.  For instance, because approximately 15% to 20% of the population moves
each year, mailings may be misaddressed or not delivered at all.  Through the
utilization of May & Speh's Merge/Purge, Address Standardization software,
National Change of Address database, Delivery Sequence File and Locatable
Address Conversion Database, the Company can eliminate most duplicate names as
well as reduce the amount of undeliverable items by an average of 6%.

     Quiddity(TM).  In fiscal year 1997, development activities were
substantially completed for Quiddity and this new product was introduced to
clients and prospects. Quiddity is an on-line relational and open database
management system designed specifically for marketing professionals. The
product's user-friendly format allows non-technical users to easily access and
directly work with marketing databases to create more targeted and profitable
one-to-one marketing programs. Quiddity integrates custom-developed and
commercial software that complement the Company's suite of direct marketing
services. Key features include open architecture, scaleable platforms and an
object-oriented application that is work-flow-oriented and intuitive.

     Information Technology Outsourcing

     May & Speh's primary information technology outsourcing service is to
manage all or a portion of a client's information processing needs on a cost-
effective basis from the Company's data center.  After migrating their workload
to the Company's data center, clients continue to retain direct access to their
information from their remote sites.  The Company also provides, to a much
lesser extent, applications outsourcing services which include the replacement
of a client's in-house technical development staff.

     The primary outsourcing services provided include migration (takeover and
turnover) support, on-line and batch processing capacity, technical support,
help desk access and support, back-up and recovery, disaster recovery services,
operations support, account management, media (tapes, documents, high speed
Direct Access Storage Devices subsystems ("DASD"), etc.) management and
handling, production control, telecommunications and network management support.
These services and support functions are available 24 hours a day, seven days a
week.

                                       4
<PAGE>
 
     Historically, the Company's success in outsourcing has resulted in part
from its ability to provide its services with minimal disruption to the client.
The Company has established rigorous formal processes to ensure a successful
ongoing processing of a client's workload at the Company's data center.

Marketing and Sales

     The Company markets its direct marketing and information technology
outsourcing services through separate direct sales forces.  Maintaining a
separate sales force for each service offering allows the Company's sales
representatives to concentrate on particular services, technology and customer
demands, thereby staying abreast of developments in these areas.  Sales
representatives are encouraged to identify cross-selling opportunities.  The
Company's sales force compensation system  provides incentives to salespeople to
focus on both attracting larger clients and selling the Company's most
profitable services.

     Pricing for direct marketing services is dependent upon the complexity of
service required.  In general, May & Speh establishes a price list for clients
detailing the prices for a broad range of service options.  These prices are
based on the nature and complexity of the services, volume of records to be
processed and the level of customization required.  Additionally, if the level
of up-front customization is high, the Company charges development fees based on
the level of customization required.

     Pricing for information technology outsourcing services is dependent upon
the anticipated range of resource consumption.  Typically, clients are charged a
flat or stepped rate for information technology outsourcing services provided
under multi-year contracts.  If the processing time, data storage, retrieval
requirements and output volume exceed the budgeted amounts, the client is
charged additional amounts.  Minimum charges and early termination charges are
typically included in contracts.

Clients

     The Company has over 180 direct marketing clients, including Fortune 500
companies and other large and medium-sized companies that have significant
direct marketing requirements.  These clients are primarily in the financial
services, consumer products, insurance, and retail industries.  The 10 largest
direct marketing clients represented approximately 66% of the Company's direct
marketing net revenues in fiscal 1997.

     The Company has approximately 150 information technology outsourcing
clients.  These clients are located primarily in the mid-western United States.
The 10 largest outsourcing clients represented approximately 40% of the
Company's information technology outsourcing services net revenues in fiscal
1997.

     The Company seeks to maintain long-term relationships with its clients.  In
fiscal 1997, 66% of net revenues were derived from clients served by the Company
for more than three years including Sears, Roebuck and Company ("Sears"), the
Company's first client in 1947.  In fiscal 1997, Sears accounted for
approximately 19.1% of the Company's net revenues.  Information technology
outsourcing clients typically operate under contracts, usually three years in
length.  Direct marketing clients typically do not operate under formal
contracts, but have traditionally maintained multi-year relationships with May &
Speh.

Technology Resources and Facilities

     The Company maintains a state-of-the-art data center with approximately
6,000 MIPS of mainframe and UNIX processing power at its Downers Grove, Illinois
headquarters. The Company's processors include and a Hitachi Skyline Series
mainframe computer, the world's fastest IBM-compatible processor, and a Hitachi
GX/8824 series mainframe computer capable of executing 390 MIPS. For outsourcing
projects, the Company has added four Hitachi Pilot processors, which are the
fastest CMOS, IBM-compatible mainframe. The Company utilizes other state-of-the-
art data center components, such as robotic tape sub-systems, RAID disk systems
and high-speed laser, LED and impact printers. The Company supports multiple
platforms including mainframe, UNIX and other mid-range computer systems.

                                       5
<PAGE>
 
     The Company maintains a disaster recovery plan with a commercial disaster
recovery service to provide alternative data processing sites in the event the
Company experiences a natural disaster or other interruption at its data center.
The Company conducts recovery exercises several times per year and encourages
its clients to join in this process.

     The Company's headquarters building was custom-designed to be a secure data
center environment.  Building characteristics include 24-hour security
protection, television surveillance, fire and motion alarms and a fire
protection system backed up by a sprinkler system.  The Company added a
generator system which allows it to be self-sufficient if there is a power
outage by operating continually until power is restored by the electric utility
provider.

Competition

     The markets in which the Company operates are highly competitive and
fragmented, with no single dominant competitor.  Although numerous smaller
companies compete in the direct marketing and outsourcing markets, the Company
regularly competes with companies that have more extensive financial, marketing
and other resources than the Company.  Many of the Company's competitors have
substantially greater assets and thus, may have a greater ability to obtain
client contracts where sizable asset purchases or investments are required.

     In the direct marketing services market, competition is based on the
quality and reliability of products and services, technological expertise,
historical experience, ability to develop customized solutions for clients,
processing capabilities and price.  Management believes that the Company
competes favorably in this market based upon these competitive factors.  The
Company's principal competitors include Acxiom Corporation, Database America
Companies, Donnelley Marketing Corp., Harte-Hanks Communication, Inc., Metromail
and NeoData Services.

     In the information technology outsourcing market, competition is based on
the quality and reliability of services, technical expertise, processing
capabilities, processing environment and price.  Management believes that the
Company competes favorably in this market based upon these competitive factors.
Although there are many competitors within the information technology
outsourcing services marketplace, the Company's principal competitors are
Affiliated Computer Services, Inc., Genix Group, Inc., a wholly-owned subsidiary
of MCN Corporation, Lockheed Martin Corporation, PKS Information Services, Inc.,
Power Computing Company  (a division of Philips, N.V.), Western Atlas and other
regional outsourcers.  In addition, but on a less frequent basis, the Company
competes with International Business Machine Corporation's Global Services
division, Electronic Data Systems Corporation, Computer Sciences Corporation,
Perot Systems, Inc. and SHL Systemhouse, Inc.

Intellectual Property Rights

     The Company relies upon its trade secret protection program and non-
disclosure safeguards to protect its proprietary technologies.  The Company
enters into license or other agreements with its clients in the ordinary course
of business which contain terms and conditions prohibiting unauthorized
reproduction of the Company's products.  In addition, the Company generally
enters into confidentiality agreements with its employees, clients, potential
clients and suppliers with access to sensitive information and limits access to
and distribution of its software documentation and other proprietary
information.  While there can be no assurance that the steps taken by the
Company will be adequate to deter misappropriation of its proprietary rights,
the Company believes that due to the rapid pace of technological change in the
Company's business, legal protections afforded through patent protection for its
products are less significant than the knowledge, ability and experience of its
employees, the frequency of product enhancements and the timeliness and quality
of support.

Employees

     As of September 30, 1997, the Company employed 574 persons.  None of the
Company's employees are represented by a labor union, and the Company believes
that its relations with employees are good.

                                       6
<PAGE>
 
Item 2.  Properties.

     The Company's executive offices and principal operations are located at
1501 Opus Place, Downers Grove, Illinois, in a 105,352 square foot building
leased from a third party for a term of 20 years.  The facility is comprised of
67,352 square feet of office space, 25,000 square feet of raised floor
facilities which house the Company's data center and 13,000 square feet of tape
library.  The Company currently leases an additional 127,448 square feet of
warehouse and office space in three separate locations in the metropolitan
Chicago area with lease terms expiring on various dates through August 2002.

     The Company has executed a 20 year lease for a 200,000 square foot office
building under construction on property adjacent to the Company's executive
offices.  The lease commences upon completion of the building which is expected
in September 1998.

     The Company believes that its existing facilities are adequate for its
present needs and that the additional facilities proposed for construction will
be sufficient to sustain the growth of the Company for the foreseeable future.
Notwithstanding, the Company believes that additional space will be available
for lease on commercially reasonable terms on an as needed basis.

     As of December 22, 1997 , there were 103 holders of record of the Company's

Dividend Policy

     The Company currently intends to retain its earnings for future growth and,
therefore, does not anticipate paying any cash dividends in the foreseeable
future.  The Company's credit agreements prohibit the Company from paying
dividends and making other distributions on its Common Stock without the consent
of its lenders.  Any future payment of dividends will depend upon the Company's
results of operations, financial condition, cash requirements and other factors
deemed relevant by the Board of Directors.

Use of Proceeds

     On March 26, 1996, the Securities and Exchange Commission declared
effective the Company's Registration Statement on Form S-1 (No. 33-98302),
pursuant to which the Company sold 4,355,000 shares of the Company's Common
Stock with aggregate offering proceeds of $47.9 million, and certain selling
stockholders sold an additional 3,350,000 shares of Common Stock with aggregate
offering proceeds of $36.9 million.  The managing underwriters of the offering
were Donaldson, Lufkin & Jenrette Securities Corporation, BT Alex. Brown, Inc.
(formerly Alex. Brown & Sons Incorporated) and ABN AMRO The Chicago Corporation
(formerly The Chicago Corporation).  The net proceeds to the Company from the
offering were approximately $43.5 million, after deducting underwriting
discounts and commissions of $3.4 million and offering expenses of approximately
$750,000 of legal, accounting, printing and other services.  The Company used
approximately $19.4 million of the net proceeds in connection with its
acquisition of GIS Information Systems, Inc. ("GIS") in July 1996 and Credit
Strategy Management ("CSM") in January 1997, and $14.5 million on purchases of
computer related equipment. The balance of the net offering proceeds are
invested primarily in securities of individual municipalities that are backed by
U.S. Treasuries or a major municipal insurer (principal and interest) and will
be used in manners similar to the above.

Item 7.  Management's Discussion and Analysis of Financial Condition and
         Results of Operations

Overview

     May & Speh celebrated it's 50th anniversary as a  provider of information
technology services in 1997. May & Speh provides computer-based information
management services with a focus on direct marketing and information technology
outsourcing services. The Company's direct marketing services help companies
execute more profitable direct marketing and customer management programs.
Services include strategic analysis and strategy management; systems consulting;
data warehouse design and management; modeling and analysis; and list
processing. May & Speh information technology solutions support multi-platform
processing, platform migration and network management for clients seeking to
outsource their information technology operations, thereby liberating capital
and redirecting their focus to more strategic information technology
initiatives.

     May & Speh has experienced strong growth in revenues and earnings per share
over the last  five years.  For the five fiscal years ended September 30, 1997,
the Company's net revenues grew from $41.8 million to $92.5 million and earnings
per share increased from $.15 to $.45.  During this period, operating margin
increased from 17.9% to 22.1%, reflecting  achievement of certain economies of
scale.  The Company has invested in human resources, facilities and technology
at rates consistent with growth in revenues over this period.  The number of
employees has increased from 272 at September 30, 1993 to 574 at September 30,
1997, reflecting the addition of new sales and marketing, technical and
administrative personnel to support the Company's emphasis on direct marketing
services along with information technology outsourcing services and overall
growth. In addition, the Company's ESOP principal payments, which have remained
relatively constant in dollar terms, have declined as a percentage of net
revenues to 2.6% for fiscal year 1997 from  5.0%  in fiscal 1993.

     In fiscal 1997, approximately 61.6% of the Company's net revenues were from
direct marketing services which include database creation, data warehousing,
predictive behavioral modeling, list processing and data enhancement.  Revenues
from the Company's existing direct marketing clients are typically recurring in
nature, though such services are not provided under long-term contracts.
Information technology outsourcing services provided approximately 38.4% of net
revenues and are typically performed under multi-year contracts.  May & Speh's
direct  marketing and information technology outsourcing services are
complementary and leverage the Company's investment in its state-of-the-art data
facility. Investments required to provide services to the new clients are
typically spread across multiple contracts.  This approach reduces the Company's
investment risk and allows for economies of scale.

     The Company regularly evaluates whether to lease or buy its computer
equipment.  An environment of rapidly changing technology and cost efficient
financing arrangements has resulted in the Company leasing most of its computer
equipment under three to ten year leases.  The Hitachi Data System Skyline 21,
which the Company purchased during fiscal year 1997 in order to better
facilitate future upgrades, is an exception.  Generally, the Company's computer
leases with terms in excess of five years are classified as capital leases.

     As of September 30, 1997, the Company had more than 330 clients. The
Company's 20 largest clients accounted for approximately 59.4% of the Company's
net revenues in fiscal year 1997. Sears represented 19.1%  of the fiscal 1997
net revenues. The Company's net revenues for fiscal 1996 and 1997 were
concentrated in the following industries:

     In October 1988, the Company established an employee stock ownership plan
to facilitate employee ownership of the Company. At the time, the ESOP acquired
43.1% of the Company's Common Stock from certain stockholders and incurred a
loan obligation of $22.5 million. As of September 30, 1997 the ESOP owned
approximately 33% of the Company's outstanding Common Stock. The loan obligation
is being repaid by the Company through annual tax deductible contributions and
as of September 30, 1997, the loan obligation was $3.0 million. ESOP
contributions are reflected in the Company's consolidated statements of
operations as "ESOP principal payments" as an operating expense and as an
interest expense.

     The Company has announced that a one-time charge of approximately $2.9
million will be recorded in the first quarter of fiscal 1998. This charge
represents the present value of payments under existing contracts with prior
members of management.

Fiscal Year Ended September 30, 1997 Compared to Fiscal Year Ended September 30,
1996

     In fiscal year 1997, net revenues increased to $92.5 million from $77.2
million in fiscal year 1996, an increase of $15.3 million or  20%. Of this net
increase, $13.7 million was attributable to new information technology
outsourcing services clients and $7.9 million  to new direct marketing services
clients. These increases were offset by a reduction in revenues of approximately
$6.5 million from credit card issuing clients. The Company's direct marketing
services revenues increased to $57.0 million for fiscal year 1997 versus $56.4
million for fiscal year 1996, an increase of 1%. The Company's information
technology outsourcing services revenues increased to $ 35.5 million for fiscal
year 1997 versus $20.8 million for fiscal year 1996, an increase of 70%.

     Wages and benefits increased to $30.4 million for fiscal year 1997 from
$24.0 million for fiscal year 1996, an increase of 27%. The increased expenses
reflect the net addition of 140 employees as a result of the Company's continued
expansion of business volume, the strengthening of its infrastructure, the 1996
acquisition of GIS Information Systems, Inc., the 1997 acquisition of Credit
Strategy Management, Inc., now known as Strategic Decision Services ("SDS"),
and the replacement of temporary labor with full-time employees during 1997.

     Services and supplies expenses decreased to $6.2 million for fiscal year
1997 from $6.8 million for fiscal year 1996, a decrease of 10%. This decrease
reflects the reduction in cost for outside consultants as full-time employees
were hired. Services and supplies generally consist of outsourced data entry
services, general supplies, contract labor and costs related to the use of
outside consultants.

     Rents, leases and maintenance expenses increased to $20.1 million for
fiscal year 1997 from $18.1 million for fiscal year 1996, an increase of 11%.
The increase was primarily due to leasing computers, computer peripheral
hardware, additional software, and additional facility rent to house print
operations and new employees. A portion of this increase was

                                      13
<PAGE>
 
due to the acquisition of GIS and its existing computer, computer peripheral
hardware, software and facility leases, and the acquisition of CSM and its
existing facility leases.

     Depreciation and amortization expenses increased to $4.4 million for fiscal
year 1997 from $2.2 million for fiscal year 1996, an increase of  105%.  The
increase was primarily attributable to continued investment in technology
including the upgrade of the Company's mainframe computer and the conversion of
the lease for the mainframe from an operating lease to a capital lease in the
fourth quarter of fiscal 1996.  The Company also purchased the Hitachi Data
System Skyline 21 mainframe computer during the third quarter of fiscal 1997.
In addition, the acquisition of GIS in the fourth quarter of fiscal year 1996
and CSM in the second quarter of fiscal year 1997 created goodwill of
approximately $21 million that is being amortized over 40 years.

     Other operating expenses increased to $8.4 million for fiscal year 1997
from $6.8 million for fiscal year 1996, an increase of 24%. The increase was
primarily attributable to variable costs relating to several client contracts.

     Research and development costs representing primarily wages and benefits
for information technology staff and reflected as such in the Company's
financial statements increased to $3.4 million for fiscal year 1997 from $2.5
million for fiscal year 1996, an increase of 38%. The Company's research and
development expenses relate primarily to new product development activities.

     Income taxes increased to $7.2 million for fiscal year 1997 from $6.3
million for fiscal year 1996. The Company's effective tax rate was 38% for
fiscal year 1997 and for fiscal year 1996.

Fiscal Year Ended September 30, 1996 Compared to Fiscal Year Ended September 30,
1995

     In fiscal year 1996, net revenues increased to $77.2 million from $61.6
million in fiscal year 1995, an increase of $15.6 million or 25%.  Of the
increase, $12.6 million was attributable to services provided to new clients and
the remainder was attributable to increased demand for services by existing
clients.  The Company's direct marketing services revenues increased to $56.4
for fiscal year 1996 versus $48.4 million for fiscal year 1995, an increase of
16%.  Of this increase, $1.7 million is attributable to the establishment of
SDS.  The Company's information technology outsourcing services revenues
increased to $20.8 million for fiscal year 1996 versus $13.2 million for fiscal
year 1995, an increase of 58%.  Of this increase, $3.4 million is attributable
to revenues from GIS.  GIS was acquired effective July 1, 1996, and sales
reflect the period from July 1, 1996 through September 30, 1996.

     Wages and benefits increased to $24.0 million for fiscal year 1996 from
$21.0 million for fiscal year 1995, an increase of 14%. The increased expenses
reflect the net addition of 103 employees as a result of the Company's continued
expansion of business volume and strengthening of its infrastructure. It also
reflects the addition of GIS' staff of 48 employees during the fiscal fourth
quarter.

     Services and supplies expenses increased to $6.8 million for fiscal year
1996 from $4.2 million for the fiscal year 1995, an increase of 64%. Services
and supplies generally consist of outsourced data entry services, general
supplies, contract labor and costs related to the use of outside consultants.
This increase resulted principally from outsourcing of technical support and
data entry services and the use of outside consultants to improve productivity
and to re-engineer certain work flow processes.

     Rents, leases and maintenance expenses increased to $18.1 million for
fiscal year 1996 from $13.9 million for fiscal year 1995, an increase of 30%.
The increase was primarily due to leasing computers, computer peripheral
hardware, additional software, and additional facility rent to house print
operations and new employees. A portion of this increase was due to the
acquisition of GIS and its existing computer, computer peripheral hardware,
software and facility leases.

     Depreciation and amortization expenses increased to $2.2 million for fiscal
year 1996 from $1.2 million for fiscal year 1995, an increase of 75%.  The
increase was primarily attributable to continued investment in technology
including the 

                                      14

upgrade of the Company's mainframe computer and the conversion of the lease
for the mainframe from an operational lease to a capital lease.

     Other operating expenses increased to $6.8 million for fiscal year 1996
from $5.1 million for fiscal year 1995, an increase of 33%. The increase was
primarily attributable to variable costs relating to several client contracts.

     Research and development costs representing primarily wages and benefits
for information technology staff increased to $2.5 million for fiscal year 1996
from $1.9 million for fiscal year 1995, an increase of 34%. The Company's
research and development expenses relate primarily to new product development
activities.

     Income taxes increased to $6.3 million for fiscal year 1996 from $4.7
million for fiscal year 1995. The Company's effective tax rate was 38% for
fiscal year 1996 and 37% for fiscal year 1995.

Liquidity and Capital Resources

     The Company's working capital increased to $47.0 million as of September
30, 1997 from $46.1 million as of September 30, 1996. The Company's investment
policy is to invest in marketable, investment-grade debt instruments of the U.S.
Government or tax-free municipal bonds. The Company's investments typically have
maturities of three years or less. The Company historically limits its
concentration of investments in individual municipalities to $500,000 or less.
These tax-free municipal bonds are backed by U.S. Treasuries or insured by a
major municipal insurer (principal and interest). As of September 30, 1997, the
Company's net accounts receivable were $28.6 million, an increase of 36% over
the previous fiscal year end. This increase primarily reflects additional
services performed for clients during August and September 1997.

     The Company has available a $2.0 million revolving credit facility.  There
were no outstanding borrowings under this credit facility during 1997.
Borrowings under a $12.0 million secured real estate loan were converted into an
unsecured term loan. This loan has a five year term at 8.5% interest. Total 
long-term debt increased $9.8 million during fiscal year 1997 as a result of a 
sale-leaseback of the Company's primary office facility and the related land.
The assets were sold at net book value. The lease is accounted for as a capital
lease (see Note 6, Notes to Financial Statements). The Company entered into a
loan at the time of the formation of the Company's Employee Stock Ownership
Plan, which currently has an outstanding balance of $3.0 million. Borrowings
under this ESOP loan are being repaid through December 31, 1998 with interest at
9.3% on the fixed portion of the loan ($2.4 million at September 30, 1997), and
at 80% of the lender's prime rate for the floating rate portion of the loan
($0.6 million at September 30, 1997), currently 6.8%. The Company received
waivers from its lenders for violations of certain financial covenants for both
the term loan and the ESOP loan.

     In connection with the Company's acquisition of GIS in 1996, the Company
agreed to pay $1 million of the purchase price on a deferred basis.  Of this
amount $500,000 was paid during the fourth quarter of fiscal 1997.  The balance
will be paid in fiscal 1998.  In addition, the Company paid $1,050,000 to the
former GIS shareholder based on the Company's earnings from former GIS clients.
During fiscal 1997, the Company completed its acquisition of Credit Strategy
Management for a cash purchase price of $1.4 million.
   
     Software development costs of $7.1 million were capitalized in fiscal 1997.
The Company does not expect research and development expenses to increase 
materially as a percentage of revenue in the future.

     Effective April 1, 1997, the Company entered into a new license agreement
with a major software vendor for software used for outsourcing services clients.
This agreement permits the Company to increase its outsourcing client base and
mainframe capacity to nearly double current levels without an increase in the
fixed license fee for seven years. While this new arrangement increased rents,
leases and maintenance expenses for the third and fourth quarters of fiscal
1997, it may provide an opportunity for increased operating margins in the
future as outsourcing revenues increase.

Impact of Year 2000 Issue

     The Year 2000 Issue is the result of computer programs being written using
two digits, rather than four, to define the applicable year. Accordingly, any of
the Company's computer programs that have date sensitive software may cause
system failures or miscalculations if data entry of "00" is recognized as 1900
rather than 2000.

     Based on a recent assessment, the Company determined that it is required to
modify portions of its software so that its computer systems will properly
utilize dates beyond December 31, 1999.  The Company believes that with upgrades
or modifications to existing software and conversion to new software, the impact
of the Year 2000 Issue can be mitigated.  However, if such upgrades,
modifications and conversions are not made, or are not made in a timely manner,
the Year 2000 Issue could have a material impact on the Company's operations.

     The Company will utilize both internal and external resources to reprogram,
or replace, and test software for Year 2000 compliance. The Company has a full-
time manager dedicated to addressing Year 2000 compliance for the Company,
clients and vendors. The Company plans to complete the Year 2000 project not
later than December 31, 1998. The total Year 2000 project cost is estimated to
be $1 million to $3 million. Amounts incurred are expected to be expensed as
incurred, unless new software is purchased which will be capitalized. The
Company has not incurred significant costs prior to September 30, 1997 other
than internal costs to evaluate the extent of Year 2000 compliance and to
develop a remediation plan.

     The costs of the Year 2000 project and the date on which the Company plans
to complete Year 2000 modifications are based on managements' best estimates,
which were derived utilizing numerous assumptions of future events including the
continued availability of certain resources, third party modification plans and
other factors. However, there can be no guarantee that these estimates will be
achieved and actual results could differ materially from those plans.

                         NOTES TO FINANCIAL STATEMENTS

NOTE 1--NATURE OF OPERATIONS AND SIGNIFICANT ACCOUNTING POLICIES

     May & Speh, Inc. ("May & Speh" or the "Company") is a provider of
computer-based information management services primarily for clients with
significant direct marketing requirements. The Company provides direct marketing
services including database creation, data warehousing, predictive behavioral
modeling list processing and data enhancement. The Company also provides
information technology outsourcing services.

     In December 1995, the Company effected a 12-for-one stock split. The
accompanying financial statements and related notes thereto have been restated
to reflect the 12-for-one stock split for all periods presented.

 Cash and cash equivalents

     The Company considers highly liquid investments with an original maturity
of 90 days or less as cash equivalents.

 Revenue recognition

     Revenue is recognized as services are performed. Direct marketing services
revenues are generally determined based upon the number of records processed and
are recognized as such processes are completed. Information technology
outsourcing services revenues are recognized based upon the amount of computer
time used. Unbilled accounts receivable consist primarily of services performed
which are billable upon project completion or upon occurrence of other specified
events. Unbilled accounts receivable are generally billed within 90 days of
income recognition. Accounts receivable are unsecured.

 Marketable securities

     Investments are stated at cost, which approximates fair market value; gains
and losses are recognized in the period realized. The Company has classified its
marketable securities as available for sale.

 Property, plant and equipment

     Property, plant and equipment are recorded at cost. Betterments are
capitalized; repairs and maintenance are expensed as incurred. Depreciation is
computed using straight-line and accelerated methods over the estimated economic
lives of the related assets as follows:

<TABLE>

          Computers and related equipment........         5 to 10 years
          Building and improvements..............      10 to 31.5 years
          Office furniture and equipment.........              12 years
          Automobiles............................               5 years
</TABLE>

 Capitalized software costs

     Development costs for software to be sold or leased to third parties is
expensed as incurred until such time as technological feasibility is
established. Upon establishment of technological feasibility, future costs are
capitalized until the product is available for general release to clients.
Amortization of capitalized software costs is the greater of the amount computed
using (a) the ratio that current gross revenues for a product bears to the total
current and future gross revenues for that product or (b) the straight-line
method over the remaining estimated economic life of the product of five to
seven years. It is reasonably possible that those estimates of

                                      21
<PAGE>
 
anticipated future gross revenues, the remaining estimated economic life of the
product or both will be reduced in the future. In addition, software costs are
generally subject to technological obsolescence in the future.
 
 Research and development costs

     The Company expenses research and development costs incurred until
technological feasibility is established. For the years ended September 30,
1995, 1996 and 1997, the Company expensed $1,860,055, $2,486,247 and $3,425,750,
respectively, as research and development costs. Research and development costs
are primarily wages and benefits for staff and are reflected as such in the
accompanying financial statements.

 Income taxes

     The Company uses the asset and liability approach under which deferred
income taxes are provided for temporary differences between the financial
reporting and income tax bases of assets and liabilities based on enacted tax
laws and rates applicable to the periods in which the differences are expected
to affect taxable income.

 Employee stock ownership plan

     Effective October 1, 1988, the Company established the May & Speh, Inc.
Employee Stock Ownership Plan (the ESOP) for the benefit of substantially all of
the Company's employees. The Company borrowed $22,500,000 from a bank (the ESOP
Loan) and loaned the proceeds to the ESOP for the purpose of providing the ESOP
sufficient funds to purchase 9,887,340 shares (43.11%) of the Company's common
stock at $2.28 per share.

     The ESOP's obligation to the Company, which is evidenced by a note (the
ESOP Note), was initially recorded as unearned compensation (a direct reduction
to shareholders' equity) and is expensed ratably as the ESOP Note is repaid. The
ESOP Note, which contains provisions substantially similar to the Company's
obligation to the bank, is secured by the unallocated ESOP shares which are
released from suspense and allocated to participants as principal is repaid. The
terms of the ESOP agreement require the Company to make minimum contributions
sufficient to meet the ESOP's debt service obligations.

 Goodwill

     In connection with its acquisition of GIS Information Systems, Inc.
("GIS") in July 1996, the Company recorded goodwill of $16,970,000. An
additional $2,416,000 was recorded during the year ended September 30, 1997
related to incentive payments and estimated costs to be incurred in
consolidating GIS's operations. The Company also recorded goodwill of $1,295,000
related to its acquisition of Credit Strategy Management, Inc. ("CSM") in 1997.
Total goodwill aggregated $20,681,000 at September 30, 1997. Accumulated
amortization totaled $106,000 and $582,000 at September 30, 1996 and 1997,
respectively. Goodwill is amortized using the straight line method over a 40-
year period for financial reporting purposes.

     The Company reviews the carrying value of goodwill and other long-lived
assets for impairment when events or changes in circumstances indicate that the
carrying amount of the asset may not be recoverable. This review is performed by
comparing estimated undiscounted future cash flows from use of the asset to the
recorded value of the asset.

 Other assets

     Other assets include cash surrender value of life insurance policies,
deposits and capitalized software costs. Capitalized software costs of
$5,218,000, and $12,305,000 are included in other assets as of September 30,
1996 and 1997, respectively. Amortization of such costs will commence when the
product is available for general release to clients.

                                      22
<PAGE>
 
 Significant clients

     Sears, Roebuck and Co. accounted for 17.1%, 17.6% and 19.1%, of the
Company's net revenues in fiscal 1995, 1996, and 1997, respectively. Capital One
Bank accounted for 10.6% of the Company's revenue in fiscal 1995.

 Per share information

     Earnings per share are based on the weighted average number of shares of
common stock and common stock equivalents outstanding during periods, computed
using the treasury stock method for stock options in accordance with Staff
Accounting Bulletin No. 83 of the Securities and Exchange Commission.

 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 reported amounts of revenues and expenses during the reporting
period. Actual results could differ from those estimates.

  Fair value of financial instruments


     The carrying amount reported in the consolidated balance sheets for cash,
marketable securities, accounts receivable, prepaid expenses and other current
assets, accounts payable and accrued expenses approximates fair value because of
the immediate or short-term maturity of these financial instruments. The
recorded value of long-term debt is estimated to approximate fair value due to
the interest rates incurred by the Company on such debt.

 New accounting pronouncements

     SFAS No. 128, "Earnings per Share," issued in February 1997, changes the
method of calculating earnings per share and will be effective for the Company's
financial statements for the year ending September 30, 1998. Earlier application
is not permitted. However, the Company is permitted to disclose pro forma
earnings per share amounts computed using this Statement in periods prior to
adoption. Upon adoption, all prior period earnings per share data presented
shall be restated to conform to this Statement. The calculation of earnings per
share under this Statement is less complex than prior methods and more
consistent with international accounting standards. Adoption of this Statement
is not expected to have a material impact on amounts previously reported as
earnings per common share.

     SFAS No. 130, "Reporting Comprehensive Income," issued in June 1997, will
require the Company to disclose, in financial statement format, all non-owner
changes in equity. Such changes include, for example, cumulative foreign
currency translation adjustments, certain minimum pension liabilities and
unrealized gains and losses on available-for-sale securities. This Statement is
effective for fiscal years beginning after December 15, 1997 and requires
presentation of prior period financial statements for comparability purposes.
The Company expects to adopt this Statement beginning with its financial
statements for the year ending September 30, 1999. Adoption of this statement is
not expected to have a material impact on the Company's financial statements.

     SFAS No. 131, "Disclosures about Segments of an Enterprise and Related
Information," issued in June 1997, establishes standards for reporting
information about operating segments in annual financial statements and interim
financial reports. It also establishes standards for related disclosures about
products and services, geographic areas and major clients. Operating segments
are components of an enterprise about which separate financial information is
available that is evaluated regularly by the chief operating decision maker in
deciding how to allocate resources and in assessing performance. Generally,
financial information is required to be reported on the basis that is used
internally for evaluating segment performance and deciding how to allocate

                                      
                                      23

resources to segments. The Company expects to adopt this Statement in its
financial statements for the year ending September 30, 1999.

     The Company determines the cost basis of its marketable securities using
the specific identification method. The net unrealized gain relating to
marketable securities is not significant and has not been reflected in the
accompanying financial statements. The Company's investments in municipal bonds
generally mature in one to three years.

 ESOP Loan

     Effective November 10, 1988, the Company entered into a $22,500,000 term
loan agreement with a bank (the ESOP Loan). Under the terms of the agreement,
the Company must make quarterly payments of principal (in varying amounts as
summarized below) plus interest. This interest rate is subject to adjustments
based upon changes in federal and state tax rates or changes in the proportion
of the bank's income from this loan which is includable in gross income for
federal income tax purposes.

     Amounts outstanding under the ESOP Loan are collateralized by the ESOP
Note, an assignment of the pledge agreement between the Company and the ESOP
(whereby the ESOP pledged the unallocated ESOP Shares as collateral for the ESOP
Note) and a security interest in all assets of the Company.

     The ESOP Loan contains certain restrictive covenants that, among other
things, limit capital expenditures, additional indebtedness, certain
investments, the repurchase of common stock and the payment of dividends and
require the Company to maintain certain working capital and other financial
measures. The Company was in violation of certain of these restrictive covenants
as of September 30, 1996 and 1997 and waivers of such violations were received
from the bank.

     On September 28, 1995, the Company's Board of Directors declared and paid a
$0.125 per share dividend. The portion of this dividend which was paid on shares
held by the ESOP (unallocated and allocated) was used to prepay $1,231,000 of
the ESOP Note and, accordingly, the Company prepaid, without penalty, $1,231,000
of the variable rate portion of the ESOP Loan.

Capital Lease Obligations

     The Company entered into a sale-leaseback agreement with a third party
selling the existing building and land, including 10.4 acres located adjacent to
the existing building that will be used to build a new 200,000 square foot
building. The Company has entered into a 20-year lease with the third party on
the existing building,

                                      26
<PAGE>
 
and it has also entered into a 20-year lease for the new 200,000 square foot
building currently under construction on the property adjacent to the Company's
executive offices. The lease commences upon completion of the building expected
to be completed in September 1998 and is classified as a capital lease. The
existing building and land were sold at its book value of approximately $12.2
million.  The interest rate implicit in the Company's capital leases 
approximates 8%.

 Term Loan

     During fiscal 1995, the Company entered into a $12,000,000 credit facility
to finance the expansion of the Company's facilities. The credit facility
requires quarterly principal payments of $200,000 plus interest at 8.5% (fixed
rate) with the balance to be paid in 2005. This credit facility contains certain
restrictive covenants that limit capital expenditures, limit additional
indebtedness, restrict certain investments, restrict the repurchase of common
stock and limit the payment of dividends. This debt agreement was amended during
fiscal 1996 to allow the acquisition of GIS Information Systems, Inc. (see Note
10). The Company is also required to maintain working capital and other
financial measures. The Company was in violation of certain of these restrictive
covenants as of September 30, 1996 and 1997. Waivers of such violations were
received from the bank.

NOTE 9--STOCK OPTION PLANS

     Effective September 30, 1994, the Company established the 1994 Executive
Stock Option Plan ("the 1994 plan"). The Company has established the 1995 Key
Employee Stock Option Plan ("the 1995 plan"), as amended and restated August 8,
1996. Under the terms of the 1994 plan, the Compensation Committee (the
Committee) of the Company's Board of Directors may grant options for the
purchase of up to 3,600,000 shares of the Company's common stock with exercise
prices and vesting requirements at the sole discretion of the Committee. The
Committee may grant options for the purchase of up to 2,000,000 shares of common
stock under the terms of the 1995 plan.

     During fiscal 1995, 1996 and 1997, the Company granted options to purchase
2,826,000, 1,130,200, and 1,305,200 respectively, shares of common stock at the
estimated fair market value at the date of grant to certain employees. The
exercise price of these options ranged from $2.08 to $19.88 per share. Options
to purchase 600,000 shares and 72,000 were canceled by the Company in fiscal
1995 and fiscal 1997, respectively. No options were canceled in fiscal 1996.
There were no options which expired or were exercised during fiscal 1995. In
fiscal 1996, 216,497 options were exercised at a weighted-average exercise price
of $2.08. In fiscal 1997, 213,200 options were exercised at a weighted-average
exercise price of $2.15.

     As of September 30, 1997, options to purchase the Company's common stock
were outstanding as follows:

     Generally, these options vest and become exercisable in five equal annual
increments beginning one year after the issue date and expire 10 years after the
issue date.

     The fair value of options at date of grant was $5.86 in fiscal 1997 and
$6.03 in fiscal 1996. These values were determined by the Black-Scholes model
with the following weighted average

                                      28
<PAGE>
 
assumptions for fiscal 1997 and 1996, respectively: interest rate of 6.63% and
6.08%; volatility of 46% and 45%; no annual dividends; and, an expected life of
8 years for all three fiscal years.

     The Company generally recognizes no compensation expense with respect to
awards of stock options since the exercise price of the common stock options
awarded are equal to the fair market value of the underlying security on the
date of grant. If the Company adopted Statement of Financial Accounting Standard
Number 123 with respect to stock options, net income would have been $10,433,192
or $0.40 per share in fiscal 1997 and $9,788,696 or $0.40 per share in fiscal
1996. The pro forma effect on net income and earnings per share for fiscal 1997
and 1996 is not representative of the pro forma effect on net income in future
years because it does not take into consideration pro forma compensation expense
related to grants made prior to September 30, 1995.

NOTE 10--ACQUISITIONS

     Effective February 3, 1997, the Company acquired the assets of Credit
Strategy Management, Inc. for $1.4 million cash. Credit Strategy Management,
Inc. provides modeling and analysis services and is located in Atlanta, Georgia.
Approximately $1.3 million of the purchase price was allocated to goodwill,
which is amortized using the straight line method over a 40-year period. The
acquisition has been accounted for under the purchase method of accounting.

     Effective July 1, 1996, the Company acquired all of the outstanding capital
stock of GIS Information Systems, Inc. ("GIS") for $16,148,000 in cash,
guaranteed deferred payments totaling $1,000,000, common stock warrants to
purchase 180,000 shares of the Company's common stock at $16.51 per share and
certain contingent payments. In connection with the acquisition, liabilities
were assumed as follows:

GIS was a provider of data processing outsourcing services and was based in Oak
Brook, Illinois.

     The fair value of the warrant to purchase 180,000 shares (which are fully
vested and expire on July 18, 2001) of the Company's common stock approximated
$1,300,000, and is included in part in capital as of September 30, 1996 and
1997. A payment of $1,050,000 was made based upon an earn-out provision for the
period July 1, 1996 through June 30, 1997. A similar additional payment is
expected based on an earn-out provision for the period July 1, 1997 through June
30, 1998. Payments made under these earn-out provisions are reflected as an
increase in goodwill. The Company reserved $1,350,000 in the first quarter of
fiscal 1997 related to costs incurred in consolidating GIS operations. These
costs were paid during fiscal 1997 and primarily consisted of rental commitments
for property having no future economic value to the Company. The amount reserved
was also included as a component of goodwill.

     The acquisition has been accounted for under the purchase method of
accounting. Accordingly, the purchase price was allocated to the identifiable
assets acquired and liabilities assumed based on their estimated fair values.
The excess of the purchase price over the net assets acquired was allocated to
goodwill. This goodwill is amortized using the straight line method over a 40-
year period for financial reporting purposes.
 
     The following unaudited pro forma financial information presents the

acquisitions had occurred at the beginning of each fiscal year. The pro forma

To the Board of Directors and
  Stockholders of May & Speh, Inc.

     In our opinion, the accompanying consolidated balance sheets and the
related consolidated statements of operations, of stockholders' equity and of
cash flows present fairly, in all material respects, the financial position of
May & Speh, Inc. and its subsidiary at September 30, 1996 and 1997 and the
results of their operations and their cash flows for each of the three years in
the period ended September 30, 1997, in conformity with generally accepted
accounting principles. These financial statements are the responsibility of the
Company's management; our responsibility is to express an opinion on these
financial statements based on our audits. We conducted our audits of these
statements in accordance with generally accepted auditing standards which
require that we plan and perform the audit to obtain reasonable assurance about
whether the financial statements are free of material misstatement. An audit
includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements, assessing the accounting principles
used and significant estimates made by management, and evaluating the overall
financial statement presentation. We believe that our audits provide a
reasonable basis for the opinion expressed above.

6.   For so long as Speh is a member of the Board or has been nominated to serve
     on the Board (provided, however, that this Paragraph 6 also shall continue
     to apply if Speh voluntarily resigns from the Board):

     (a)  Neither Speh nor any person, corporation or other entity controlled by
          or under common control with Speh (the "Investor Group") shall solicit
          proxies or become a "participant" in a "solicitation" (as such terms
          are defined in Regulation 14A under the Exchange Act) or seek to
          advise or influence any person or entity with respect to the voting of
          (or giving of consents with respect to) any Common Stock or other
          voting securities of the Employer in opposition to the recommendation
          of the majority of the directors of the Employer with respect to any
          matter.

     (b)  No member of the Investor Group shall join a partnership, limited
          partnership, syndicate or other group (within the meaning of Section 
          13(d)(3) of the Exchange Act), or otherwise act in concert with any
          other person, for the purpose of acquiring, holding, voting, giving of
          consents, or disposing of shares of Common Stock or other voting
          securities of the Employer.

     (c)  Neither Speh nor any member of the Investor Group shall (i) either
          alone, or in concert with others, seek to control or influence
          the management, Board or policies of the Employer, (ii) tender shares
          of Common Stock or other securities of the Employer in a hostile
          tender offer or exchange in opposition to a Board recommendation, or
          (iii) solicit, induce or encourage any offer to acquire the Employer,
          its securities or assets or a merger or consolidation involving the
          Employer.

7.   Speh, on the one hand, and the Employer, on the other, acknowledge and
     agree that irreparable damage would occur in the event any of the
     provisions of Paragraphs 4, 5 and 6 were not performed in accordance with
     their specific terms or were otherwise breached. It is accordingly agreed
     that the parties shall be entitled to an injunction or injunctions to
     prevent breaches of the provisions of Paragraphs 4, 5 and 6 of this
     Agreement and to enforce specifically the terms and provisions hereof in
     any court of the United States or any state thereof having jurisdiction,
     without the necessity of posting bond, in addition to any other remedy to
     which they may be entitled at law or equity.

8.   At any time after the effective date of this First Amendment, Speh may, on
     one occasion only, request registration under the Securities Act of 1933
     ("Securities Act") of all or part of the Common Stock owned directly or in
     a fiduciary capacity by him. A registration requested pursuant to this
     Paragraph 8 is referred to as "Demand Registration".

                                       2
<PAGE>
                                                   
     (a)  If a Demand Registration is in an underwritten public offering and the
          managing underwriters advise the Employer in writing that in their
          opinion the number of securities requested to be included in such
          registration exceeds the number which can successfully be sold in such
          offering, the Employer will exclude from such registration the number
          of shares of Common Stock requested to be included by Speh which in
          the opinion of such underwriters can not be successfully sold.

     (b)  Notwithstanding the provisions of Paragraph (a) to the contrary, the
          Employer may postpone, for up to 120 days, the filing or the
          effectiveness of a registration statement for a Demand Registration if
          the Employer reasonably believes such Demand Registration would have
          an adverse effect on any proposal or plan by the Employer or any of
          its subsidiaries to engage in any acquisition of stock or assets or
          any merger, consolidation, tender offer or other significant
          transaction or to permit the Employer to avoid a special audit.

     (c)  If the Employer has previously filed a registration statement, and if
          such previous registration has not been withdrawn or abandoned, Speh
          agrees not to exercise a Demand Registration until a period of 180
          days has elapsed from the effective date of such previous
          registration.

9.   Whenever, from the date of this First Amendment and through the term of the
     Agreement the Employer proposes to register any of its securities under the
     Securities Act (except on Form S-4 or S-S or any successor forms), the
     Employer will give prompt written notice to Speh of the Employer's
     intention to effect such a registration and the Employer will use
     commercially reasonable efforts to include in such registration all Common
     Stock owned directly or in a fiduciary capacity by Speh with respect to
     which Speh has given the Employer written request for inclusion therein
     within fifteen days after the giving of the Employer's notice to Speh (a
     "Piggyback Registration").

     (a)  If a Piggyback Registration is a part of an underwritten primary
          registration on behalf of the Employer, and the managing underwriters
          advise the Employer in writing that in their opinion the number of
          securities requested to be included in such registration exceeds the
          number which can successfully be sold in such offering, the Employer
          will include in such registration (i) first, the number of securities
          the Employer proposes to sell and (ii) second, the registrable
          securities requested to be included in such registration which in the
          opinion of such underwriters can be successfully sold, such securities
          to be taken from the holders of such registrable securities pro rata
          on the basis of the number of shares of such securities for which the
          Employer has been given written requests for inclusion therein by each
          such holder thereof. In the event of a non-underwritten public
          offering, the Employer's Board may in its reasonable and good faith
          judgment impose such limitations.

     (b)  If at Piggyback Registration is a part of an underwritten secondary
          registration on behalf of holders of the Employer's securities, and
          the managing underwriters

                                       3
<PAGE>
                                                                              
          advise the Employer in writing that in their opinion the number of
          securities requested to be included in such registration exceeds the
          number which can successfully be sold in such offering, the Employer
          will include in such registration (i) first, the securities requested
          to be included therein by the holders requesting such registration and
          (ii) second, the registrable securities requested to be included in
          such registration which in the opinion of such underwriters can
          successfully be sold, such securities to be taken from the holders of
          such registrable securities pro rata on the basis of the number of
          shares of such securities for which the Employer has been given
          requests for inclusion therein by each such holder thereof. In the
          event of a non-underwritten public offering, the Employer's Board may
          in its reasonable and good faith judgment impose such limitations.

10.  Speh agrees and covenants that he shall not effect any sale, transfer or
     other distribution of equity securities of the Employer, or any securities
     convertible into or exchangeable or exercisable for such securities, during
     the fourteen days prior to and the 90-day period beginning on the effective
     date of any underwritten primary registration or secondary registration of
     the Common Stock (except as part of such registration). The Employer shall
     have the right to select the underwriters in any underwritten registration.

11.  If Speh requests that any Common Stock be registered in a Demand
     Registration or a Piggyback Registration pursuant to this Agreement, the
     Employer will use commercially reasonable efforts to effect the
     registration and the sale of such Common Stock, in accordance herewith and
     with the intended method of disposition thereof, and pursuant thereto the
     Employer will as expeditiously as reasonably practicable:

     (a)  prepare and file with the Securities and Exchange Commission (the
          "Commission") a registration statement with respect to such Common
          Stock and use commercially reasonable efforts to cause such
          registration statement to become and remain effective for such period,
          not to exceed six months, as may be reasonably necessary to effect the
          sale of such securities;

     (b)  prepare and file with the Commission such amendments and supplements
          to such registration statement and the prospectus used in connection
          therewith as may be necessary to keep such registration statement
          effective for a period, which need not exceed six months, and comply
          with the provisions of the Securities Act, with respect to the
          disposition of all securities covered by such registration statement
          during such period in accordance herewith and with the intended
          methods of disposition by the sellers thereof set forth in such
          registration statement;

     (c)  furnish to Speh such number of copies of such registration statement,
          each amendment and supplement thereto the prospectus included in such
          registration statement (including each preliminary prospectus) and
          such other documents as Speh may reasonably request in order to
          facilitate the disposition of such Common Stock owned by Speh; and

                                       4
<PAGE>
 
     (d)  list such Common Stock on the principal exchange or market for the
          Common Stock and register or qualify such Common Stock under such
          other securities or blue sky laws of such jurisdictions as Speh
          reasonably requests and do any and all other acts and things which may
          be reasonably necessary or advisable to enable Speh to consummate the
          disposition in such jurisdictions of the Common Stock owned by Speh
          (provided, however, that the Employer will not be required to (i) in
          the case of a Piggyback Registration, register or qualify such Common
          Stock in any jurisdiction where shares to be sold by the Employer are
          not to be registered or qualified, (ii) qualify generally to do
          business in any jurisdiction where it would not otherwise be required
          to qualify but for this subparagraph, (iii) subject itself to taxation
          in any such jurisdiction, or (iv) consent to general service of
          process in any such jurisdiction).

12.  All expenses incident to the Employer's performance of a Demand or
     Piggyback Registration, including, without limitation, all registration and
     filing fees, fees and expenses of compliance with securities or blue sky
     laws, printing expenses, messenger and delivery expenses, and fees and
     disbursements of the Employer's independent certified public accountants
     and legal counsel, and other persons retained by the Employer, shall be
     borne by the Employer, provided, however, underwriting discounts and
     commissions, any selling commissions and taxes attributable to the Common
     Stock sold by or on behalf of Speh and fees and expenses of any counsel
     engaged by Speh shall be borne by Speh.

13.  In connection with any registration statement in which Speh is
     participating, Speh will furnish to the Employer in writing such
     information and affidavits as the Employer reasonably requests for use in
     connection with any such registration statement or prospectus or any
     amendment thereof or supplement thereto and, in any underwritten
     registration, Speh will enter into and execute an underwriting agreement
     in the form reasonably requested by the underwriters.

14.  The Employer will pay Speh's legal costs (up to $5,000.00) incurred in the
     negotiation and preparation of this First Amendment.

     IN WITNESS WHEREOF, the parties have signed this First Amendment on the
date first written above.

      6.4  DEFECTS AND REMOVAL OF LIENS.
           ---------------------------- 

     (a) Defects.  If the Title Commitment or the Title Policy discloses Title
Defects, or if the Survey discloses Title Defects then Seller shall have thirty
(30) days from the date of the delivery of the Title Commitment and Survey in
which to have such Title Defects removed from the Title Commitment or Title
Policy, or to remove such defects in the Survey or have the Title Company commit
to insure over same. If such unpermitted exceptions or defects are not removed
or insured over within the permitted time, Purchaser may elect, in addition to
Purchaser's remedies under Section 10.2 hereof, upon written notice to Seller
made within ten (10) days after the expiration of the permitted time (i) to
terminate this Agreement; (ii) to extend the permitted time for fifteen (15)
days in which such exceptions or defects may be removed or insured over; or
(iii) take title as it then is and deduct from the Purchase Price an amount
necessary to discharge and to obtain affirmative title insurance against loss
with respect to any unpermitted liens, encumbrances or restrictions. If
Purchaser fails to make a timely election, such failure shall constitute an
election under clause (ii) above to extend the permitted time in which such
exceptions or defects may be removed or insured over for an additional period of
fifteen (15) days and if such Title Defects are not removed or satisfactorily
insured over within said fifteen (15) days and Purchaser does not elect to
proceed under clause (iii) above within said time, Purchaser shall be deemed to
have elected to terminate this Agreement.  Title Defects which are accepted by
Purchaser pursuant to clause (iii) shall thereupon be deemed to be Permitted
Exceptions and Exhibit "E" shall be amended, if necessary, to include such
additional Permitted Exceptions.

     (b) Removal of Liens.  If on the Closing Date there shall be any Title
Defect of a definite or ascertainable amount which is capable of satisfaction by
the payment of money, then Seller shall either (a) use a portion of the Purchase
Price to satisfy the same, provided Seller shall simultaneously deliver to
Purchaser at the Closing instruments, in recordable form, sufficient to satisfy
such Title Defect of record, together with the cost of recording or filing said
instrument; or (b) in the alternative, make arrangements with the Title Company
in advance of Closing whereby Seller will deposit with the Title Company
sufficient monies (which may be a portion of the Purchase Price), acceptable to
the Title Company, to induce the Title Company to issue the Title Policy to
Purchaser, either free of any such Title Defect or with insurance which "insures
over" such Title Defect.

      6.5  ESCROW.  This Agreement shall not be merged into the Escrow
Instructions but the Escrow Instructions shall be deemed auxiliary to this
Agreement and, as between the parties hereto, the provisions of this Agreement
shall govern and control.

and ch. 48, para. 750 (1987). If such evidence is not so delivered to Purchaser,
then Seller shall, or Purchaser may, notify the Department and the Illinois
Department of Labor of the pending sale and request the Department and
Department of Labor to make a determination as to whether the Seller has an
assessed, but unpaid taxes and contributions for unemployment compensation. The
parties shall withhold in the Escrow any amounts required by the Department or
the Department of Labor until the appropriate agency furnishes Seller and
Purchaser with a letter advising that all sales and income taxes and
contributions for unemployment compensation due to the State of Illinois from
the Seller have been paid and releasing Purchaser from any withholding

     (iii) Within twenty (20) days after the Agreement Date, Seller shall
deliver to Purchaser a fully completed and executed disclosure document for the
Property pursuant to the Illinois Responsible Property Transfer Act, Ill. Rev.

bid, submission of proposal or offer to purchase, lease or manage the Property

any person any information with respect to or otherwise cooperate with, assist,

               (ii) Except for the final draw, the maximum amount of any draw
          shall not exceed an amount which bears the same ratio to the portion
          of the Repair Allowance applicable to the work being done by Tenant as
          the cost of such work paid by Tenant and covered by the lien waivers
          submitted by Tenant in connection with the draw request bears to the
          total cost of such work;

               (iii) With each draw request Tenant shall submit to Landlord the
          following documents:

                    (A) A true and correct copy of the application for payment
               by Tenant's contractors for the work in question completed to

                    (D) The total cost of the work in question based on the
               plans approved by Landlord, as such cost may change from time to
               time;

                                      -4-
<PAGE>
 
                    (E) With the final draw request, Tenant shall submit to
               Landlord a certificate from Tenant's architect stating that
               Second Floor Alterations for the work in question has been
               completed in accordance with the Plans approved by Landlord and
               applicable zoning, building, environmental and other laws.

               (iv) Landlord will disburse the portion of the Repair Allowance
          allocable to each draw request to Tenant or Tenant's contractors (at
          Tenant's option) within thirty (30) days after Tenant has submitted
          the required information for such draw and has otherwise complied with
          the requirements hereof.

     S.4  Tenant's Option To Purchase.  If Tenant exercises its option under
the 3333 Lease to purchase the premises under such lease on the Closing Date
defined below, then Tenant shall have the option to purchase the Premises on
September 1, 2001 or September 1, 2006 (the applicable date chosen by Tenant
herein called the "Closing Date") on the terms and conditions set forth in the
Purchase Contract attached hereto as Rider E ("Purchase Contract"). Tenant shall
exercise such option by delivery of written notice to Landlord on or before
February 1 preceding the Closing Date exercising such option and four copies of
the Purchase Contract, with the Closing Date and Purchase Price filled in,
executed by Tenant. Time is of the essence in the exercise of the option to
purchase set forth in this Section S.4. If Tenant exercises the option as set
forth in this Section, Landlord shall execute the Purchase Contract and deliver
two executed copies thereof to Tenant. The Premises shall be purchased on the
terms and conditions set forth in the Purchase Contract.

     S.5  Net Lease.  This is an absolutely net lease to Landlord. It is the
intent of the parties hereto that the Base Rent payable under this Lease shall
be an absolutely net return to the Landlord and that the Tenant shall pay all
costs and expenses relating to the Premises and the business carried on therein,
unless otherwise expressly provided in the Lease. Any amount or obligation
relating to the Premises which is not expressly declared to be that of Landlord
shall be deemed to be an obligation of the Tenant to be performed by the Tenant
at the Tenant's expense. In addition, Tenant acknowledges that it is conveying
title to the Premises to Landlord prior to the execution of this Lease and that
in connection with the sale of the Premises from Tenant to Landlord, no
prorations with respect to Taxes or other expenses or obligations incurred with
respect to the Premises prior to the Commencement Date have been made on the
understanding that all such costs will be paid by Tenant. Accordingly, all Taxes
and other costs and expenses incurred with respect to the Premises prior to the
Commencement Date shall be paid by Tenant, as additional rent, under this Lease.

     S.6  Right of First Offer.

          (a)  Landlord hereby grants to Tenant, the right of first offer on any
     disposition of the Premises (as defined in Section 4.02(c)) excepting those
     dispositions specified in Section S.6(b) below and subject to Section
     S.6(c) below.

                                      -5-
<PAGE>
 
          (b) This right of first offer shall not apply to the following
     dispositions of the Premises:

               (i) any dispositions to any person or party who may acquire an
          interest in the Premises in the nature of a security interest for a
          bona fide obligation of any party owning an interest in the Premises
          or any transferee thereof, whether by way of pledge, collateral
          agreement, or mortgage,

               (ii) any person or party who may acquire an interest in the
          Premises as a result of the enforcement (or transfer in lieu of
          enforcement) of any bona fide obligation secured by an interest in the
          Premises, or any transferee thereof, whether by way of purchase at any
          Sheriff, judicial, or other sale, termination of lease and eviction of
          the lessee thereunder, or any other remedy to which the holder of said
          obligation is entitled,

               (iii) any disposition to a Landlord Affiliate.

               (iv) a leasehold interest in space in the Building, or

               (v) any disposition after September 1, 2006.

          (c) If Landlord shall desire to dispose of (any type of disposition is
     hereinafter called "sale") the Premises in a transaction not excepted by
     Section S.6(b), Landlord shall give Tenant written notice to that effect
     which notice shall specify the price and financial terms ("Landlord's Price
     and Terms") on which Landlord is willing to sell the Premises. Tenant shall
     have the right at anytime during the thirty (30) day period following the
     giving of such notice to give Landlord notice:

               (i) that Tenant will purchase the Premises at Landlord's Price
          and Terms, in which event the closing of said purchase shall occur on
          a date selected by Tenant which date shall be between sixty (60) and
          ninety (90) days after Tenant gives such notice;

               (ii) of the price and financial terms ("Tenant's Price and
          terms") on which Tenant is willing to purchase the Premises and the
          proposed closing date for said purchase which shall be between sixty
          (60) and ninety (90) days after the giving of such notice, or

               (iii) that Tenant waives its right of first offer to purchase the
          Premises.

          (d) If Tenant gives the notice stated in Section S.6(c)(ii) then
     Landlord by written notice to Tenant within thirty (30) days after receipt
     of Tenant's Notice, shall elect either:

                                      -6-
<PAGE>
 
               (i) to sell the Premises at Tenant's Price and Terms, in which
          event the closing of such sale shall occur on the closing date set
          forth in Tenant's notice, or

               (ii) not to sell the Premises to Tenant at Tenant's Price and
          Terms.

          If Landlord fails to give Tenant any such notice within said thirty
     (30) day period, Landlord shall be deemed to have given the notice
     specified in (ii) immediately above.

          (e)  (i)  If Landlord gives or is deemed to have given the notice
          specified in Section S.6(c)(ii), Landlord may enter into a written
          agreement to sell the Premises at any time during the one hundred
          eighty (180) day period after receipt of Tenant's notice for a price
          and terms equal to or greater than (but not less than) Tenant's Price
          and Terms. If Landlord does not enter into said written agreement
          within said one hundred eighty (180) day period, or, if said agreement
          is entered into, Landlord does not close the sale within two hundred
          seventy (270) days after receipt of Tenant's notice, at a price and
          terms equal to or greater than Tenant's Price and terms, then Landlord
          may not sell the Premises without again giving Tenant notice of its
          desire to sell the Premises as required by Section S.6(c).

               (ii) If Tenant gave or is deemed to have given the notice in
          Section S.6(c)(iii) then Landlord may enter into a written agreement
          to sell the Premises at any time during the one hundred eighty (180)
          day period after receipt of Tenant's notice or if no notice is given
          within two hundred forty (240) days after Landlord's Notice on any
          terms and conditions. If Landlord does not enter into said written
          agreement within said one hundred eighty (180) or two hundred forty
          (240) day period, or, if said agreement is entered into, Landlord does
          not close the sale within two hundred seventy (270) days after receipt
          of Tenant's notice or three hundred thirty (330) days after Landlord's
          Notice, as the case may be, then Landlord may not sell the Premises
          without again giving Tenant notice of its desire to sell the Premises
          as required by Section S.6(c).

          (f) If Tenant does not purchase the Premises offered pursuant to this
     Section S.6 and the Premises is sold by Landlord in accordance with this
     Section S.6, then Tenant shall have no further right of first offer under
     this Section S.6 to purchase the Premises but nothing herein shall affect
     Tenant's option to purchase the Premises pursuant to Section S.4 above.

          (g) At such time as the rights of first offer of Tenant hereunder
     shall cease and be at an end and null and void, then at Landlord's request
     Tenant shall execute and deliver to Landlord an instrument in recordable
     form releasing all of its right under this Section S.6, which instrument
     may be filed of record.

                                      -7-

          (h) In the event request is made of Tenant for written confirmation
     that any proposed transaction is not subject to the rights of first offer
     granted to Tenant pursuant to the provisions of this Section S.6, then if
     Tenant has knowledge of said fact and if such is the case, Tenant, within
     ten (10) days after notice of the proposed transaction and requested
     confirmation, shall execute and deliver to the holder of any interest in
     the Premises requesting said confirmation, a written statement confirming
     that Tenant does not have the right of first offer with respect to said
     proposed transaction.

          (i) Except for the Closing Date and the Price and Terms described
     above, Tenant shall purchase the Premises on the terms and conditions set
     forth in the Purchase Contract. Within ten (10) days after Tenant accepts
     Landlord's Price and Terms or Landlord accepts Tenant's Price and Terms,
     Tenant shall deliver to Landlord four (4) copies of the Purchase Agreement
     modified to reflect the applicable Price and Terms, the Closing Date and
     the property to be purchased. Within ten (10) days thereafter, Landlord
     shall execute such Purchase Contract and deliver two (2) execution copies
     to Tenant.

          (j) If Landlord sells the Premises pursuant to Section S.6(e) above
     for a price (before deduction for the costs and expenses incurred in
     connection with such sale) ("Sales Price") in excess of the Applicable
     Option Price, then Landlord shall pay to Tenant an amount equal to fifty
     percent (50%) of the Excess Sale Proceeds (as defined below) at the same
     time and in the same manner as such Excess Sale Proceeds are paid to
     Landlord by the purchaser of the Premises. This Section S.6(j) shall not
     apply to any disposition of the Premises described in Section S.6(b). As
     used in this Section S.6(j):

               (i) "Applicable Option Price" shall mean the Purchase Price
          determined pursuant to Section 3.1 of the Purchase Contract attached
          hereto as Rider E assuming (x) the Closing Date under such Contract
          was the date the Premises was sold by Landlord and (y) the Total
          Project Costs, as such term is used in the Purchase Contract means the
          sum of (aa) $7,236,000, (bb) the portion of the $500,000 Repair
          Allowance described in Section S.2 of this Lease which has been paid
          by Landlord and (cc) all other costs expended by Landlord to acquire
          the Premises from Tenant pursuant to the Purchase and Sale Agreement.

               (ii) "Excess Sale Proceeds" shall mean the Sale Price less the
          Applicable Option Price and all costs and expenses incurred by
          Landlord to sell the Premises, including without limitation,
          prorations, attorney fees, title insurance and transfer taxes.

          (k) As used herein "Landlord Affiliate" shall mean any natural person
     or any firm, corporation, partnership, limited liability company,
     association, trust or other entity which, directly or indirectly, controls,
     or is under common control with landlord (or if Landlord is an Illinois
     land trust, the holder of the beneficial interest in such land trust) and
     any firm, corporation, partnership, association, trust or other entity
     which is

                                      -8-

     controlled by Landlord (or if Landlord is an Illinois land trust, the
     holder of the beneficial interest in such land trust). For purposes hereof,
     the term "control" shall mean the possession, directly or indirectly, of
     the power to direct or cause the direction of the management and policies
     of any entity or the power to veto major policy decisions of any entity,
     whether through the ownership of voting securities, by contract, or
     otherwise.

all other amounts becoming due from Tenant to Landlord hereunder (hereinafter
collectively referred to as "Rent") shall be paid in lawful money of the United
States to Landlord at the office of Landlord, or as otherwise designated from
time to time by written notice from Landlord to Tenant. The payment of Rent
hereunder is independent of each and every other covenant and agreement
contained in this Lease, and Rent shall be paid without any setoff, abatement,
counterclaim or deduction whatsoever except as may be expressly provided herein.


                                   ARTICLE 4.
                                     TAXES

     4.01 Obligation to Pay Tax Rent Adjustments. In addition to paying
Base Rent specified in Section 3.01, Tenant shall also pay, as additional rent,
the amount of the Taxes due for each Adjustment Year (hereinafter referred to as
"Tax Rent Adjustments").  Tenant agrees and acknowledges that Landlord has made
no representation, warranty or guaranty relating to the amount of Taxes. Tenant
has not relied upon any statements or representations of Landlord or any agent
or affiliate of Landlord in regard to Taxes in executing this Lease and agreeing
to perform the terms and covenants hereof and shall make no claim against
Landlord based thereon.

     4.02 Definitions. As used in this Lease,

          (a) "Adjustment Year" shall mean the calendar year in which the
Expiration Date falls and each calendar year prior to such date.

          (b) "Taxes" shall mean real estate taxes, general or special
assessments, sewer rents, rates and charges, transit and transit district taxes,
taxes based upon the receipt of rent, and any other federal, state or local
governmental charge, whether general, special, ordinary or extraordinary (but
not including income or franchise taxes or any other taxes imposed upon or
measured by Landlord's income or profits, except as provided herein), which may
now or hereafter be levied, assessed or imposed against the Real Property.

     Notwithstanding anything contained in this clause (b) to the contrary:

          (i) If at any time the method of taxation then prevailing is
     altered so that any new or additional tax, assessment, levy, imposition or
     charge or any part thereof is imposed upon Landlord in place or partly in
     place of any such Taxes or contemplated increase therein, or in addition to
     Taxes, and is measured by or is based in whole or in part upon the Real
     Property or the rents or other income therefrom, then all such new taxes,
     assessments, levies, impositions or charges or part thereof, to the extent
     that they are so measured or based, shall be included in Taxes levied,
     assessed or imposed against the Real Property to the extent that 

                                      -11-
<PAGE>
 
     such items would be payable if the Real Property were the only property of
     Landlord subject thereto and the income received by Landlord from the Real
     Property were the only income of Landlord.

                 (ii)  Notwithstanding the year for which any such taxes or
     assessments are levied, (A) in the case of taxes or special assessments
     which may be paid in installments, the amount of each installment, plus any
     interest payable thereon, paid during a calendar year shall be included in
     Taxes for that year and (B) if any taxes or assessments payable during any
     calendar year shall be computed with respect to a period in excess of
     twelve (12) calendar months, then taxes or assessments applicable to the
     excess period shall be included in Taxes for that year.  Except as provided
     in the preceding sentence, all references to Taxes "for" a particular year
     shall be deemed to refer to taxes levied, assessed or otherwise imposed for
     such year without regard to when such taxes are payable.

                 (iii)  Taxes shall also include any personal property taxes
     (attributable to the calendar year in which paid) imposed upon the
     furniture, fixtures, machinery, equipment, apparatus, systems and
     appurtenances which are components of the Real Property.

          (c) "Real Property" means the Building and Land.

      4.03 Payments of Tax Rent Adjustments. Tenant shall pay Tax Rent
Adjustments to Landlord as follows:

          (a) Promptly after receipt of a statement from the appropriate
authority for any installment (including any estimated installment) of Taxes
payable during an Adjustment Year, Landlord shall furnish Tenant a written
notice ("Tax Installment Statement") setting forth the amount of Taxes shown to
be due on such statement of Taxes.  Within fifteen (15) days after receipt of
Landlord's Tax Installment Statement, Tenant shall pay to Landlord the Tax
Adjustment shown as due on the Tax Installment Statement.

          (b) Prior to the end of the final Adjustment Year, Landlord shall
deliver to Tenant a written notice ("Final Year Tax Notice") setting forth
Landlord's reasonable estimate, forecast or projection (the "Tax Projection") of
Taxes (1) applicable to any prior Adjustment Year which have not yet been paid
by Tenant to Landlord and (2) applicable to such final Adjustment Year.  Within
fifteen (15) days following Landlord's delivery of the Final Year Tax Notice,
Tenant shall pay Landlord the Tax Projection shown on the Final Year Tax Notice.
Any Tax Projection paid by Tenant for any Adjustment Year shall be applied as a
credit against the amounts owed by Tenant for such Adjustment Year pursuant to
subparagraph (a) above, provided that if the Taxes for such Adjustment Year are
payable in installments, the Tax Projection applied as a credit shall be divided
equally among the installments to be paid by Tenant.

                                      -12-
<PAGE>
 
          (c) If any First Mortgagee, as defined in Section 18.01 requires
periodic deposits for Taxes or other security for the payment of Taxes, Tenant
shall pay such periodic deposits to Landlord when and as required by the First
Mortgagee or provide such security to the First Mortgagee.  Any deposits made by
Tenant for an Adjustment Year shall be applied as a credit against Taxes payable
by Tenant pursuant to subparagraph (a) above and any Tax Projection required
under subparagraph (b) above.  Landlord shall use reasonable efforts to exclude
from the First Mortgage documents any requirement for periodic deposits of Taxes
or other security for the payment of Taxes.  If Landlord is unable to eliminate
the requirement for periodic deposits of Taxes, Landlord shall use reasonable
efforts to have such deposits held in an interest bearing account with the
interest to be held for Tenant's account.

     4.04  Proration and Survival. If the final Adjustment Year does not fall
entirely within the Term, Tenant shall be obligated to pay as Tax Rent
Adjustments for such Adjustment Year only a pro rata share of Tax Rent
Adjustments as herein determined, based upon the number of days of the Term
falling within the Adjustment Year. Following expiration or termination of this
Lease, Tenant shall pay any Tax Rent Adjustments due to Landlord within fifteen
(15) days after the date of each Landlord's Statement sent to Tenant. Without
limitation of other obligations of Tenant which shall survive the expiration of
the Term, the obligation of Tenant to pay Tax Rent Adjustments under this
Article 4 shall survive the expiration or termination of this Lease.


                                   ARTICLE 5.
                                USE OF PREMISES

     Tenant shall use and occupy the Premises for general office purposes and
uses incidental thereto permitted under law and for no other use or purpose.


                                   ARTICLE 6.
                                   UTILITIES

     6.01  Payment for Utilities. Tenant will pay, when due, all charges of
every nature, kind or description for utilities and other services furnished to
the Premises prior to or during the Term or chargeable against the Premises with
respect to the Term or any period prior to the Commencement Date, including all
charges for water, sewage, heat, gas, light, garbage, electricity, telephone,
steam, power, or other public or private utility services.

     6.02  Utilities. Tenant shall be responsible for contracting directly
with all suppliers of utility services. In the event that any charge or fee is
required by the State of Illinois, or by any agency, subdivision or
instrumentality thereof, or by any utility company or other entity furnishing
services or utilities to the Premises, as a condition precedent to furnishing or
continuing to furnish utilities or services to the Premises, such charge or fee
shall be deemed to be a utility charge payable by Tenant. The provisions of this
paragraph shall include, but shall not be limited to, any charges or fees for
present or future water or sewer capacity to serve the

                                     -13-

<PAGE>
 
Premises, any charges for the underground installation of gas or other utilities
or services, and other charges relating to the extension of or change in the
facilities necessary to provide the Premises with adequate utility services.  In
the event that Landlord has paid any such charge or fee after the date hereof,
Tenant shall reimburse Landlord for such utility charge upon Landlord's demand
therefor. The inability of Tenant to obtain, or any stoppage of, the utility
services referred to in this Article 6 resulting from any cause shall not
constitute a constructive eviction, shall not make Landlord liable in any
respect for damages to any person, property or business, and shall not entitle
Tenant to any abatement of Rent or other relief from any of Tenant's obligations
under this Lease.


                                   ARTICLE 7.
                   CONDITION, CARE AND OPERATION OF PREMISES

     7.01 Condition of Premises. Tenant's taking possession of the Premises
or any portion thereof shall be conclusive evidence against Tenant that the
Premises were then in good order and satisfactory condition.

     7.02 Tenant's Maintenance and Operation Obligations. Tenant shall keep the
Premises, including any improvements thereto by Tenant, in good order and in a
safe, neat and clean condition and will take all action and will make, except as
otherwise stated herein, all structural and nonstructural, foreseen and
unforeseen and ordinary and extraordinary changes, repairs and replacements.
Tenant's obligations under this Article shall include without limitation all
repairs and replacements to the roof, structure, supports, foundation, floors,
gutters, downspouts, windows, doors, exterior walls, parking areas, and
sidewalks, the maintenance of the landscaping on the Premises in a neat and
attractive condition and the removal of all snow and ice from the walkways,
parking areas and drives on the Premises and the operation, maintenance and
repair of all building systems. It is the intent of the parties hereto, that
Tenant shall bear all responsibility for the maintenance, upkeep and replacement
of the Premises, Building and Land. Tenant's operation, maintenance and repair
of the Premises shall be conducted in accordance with the standards set forth on
Rider F attached hereto and made a part hereof. In the event Tenant fails to
commence promptly and pursue diligently the performance of such maintenance or
the making of such repairs or replacements, then Landlord, at its option, may
perform such maintenance or make such repairs and replacements and Tenant shall
reimburse Landlord, on demand after Tenant receives an invoice therefor, the
cost thereof plus a fee equal to fifteen percent (15%) of the actual costs to
cover the overhead. If Tenant incurs any costs in connection with its
maintenance and repair obligations with respect to the base building
improvements during the last five (5) years of the Term or any Extended Term
(last seven (7) years in the case of a replacement of the roof of the Building)
which under generally accepted accounting principles ("GAAP") is required to be
capitalized and depreciated ("Base Building Capital Costs") and the Term of this
Lease expires prior to the end of the applicable depreciation period under GAAP,
then upon expiration of this Lease, Landlord shall pay to Tenant a pro rata
portion of such costs based on the ratio of the portion of the depreciation
period not included within the Term to the total depreciation period. Tenant
shall not incur any

                                      -14-
<PAGE>
 
Base Building Capital Costs without Landlord's prior written consent.

     7.03  Work Performed by Tenant. All repairs made by Tenant pursuant to
Section 7.02 shall be performed in a good and workmanlike manner by contractors
or other repair personnel selected by Tenant and approved by Landlord. All
contracts for such maintenance and repair services shall be subject to
Landlord's reasonable approval. In no event shall such work be done for
Landlord's account or in a manner which allows any liens to be filed against the
Building or the Premises in violation of Article 27.

     7.04  Janitorial Service. Tenant shall be responsible for providing
janitorial service for the Premises at Tenant's sole cost and expense in
accordance with the standards attached hereto as Rider C. Such janitorial
service shall be performed by a company and pursuant to a contract reasonably
satisfactory to Landlord.

     7.05 Waste.  Tenant shall not do or suffer any waste or damage,
disfigurement or injury to the Premises, or any improvements hereafter erected
thereon, or to the fixtures or equipment therein, or permit or suffer any
overloading of the floors or other use of the improvements that would place an
undue stress on the same or any portion thereof beyond that for which the same
was designed.


                                   ARTICLE 8.
                               RETURN OF PREMISES

     8.01 Surrender of Possession. At the termination of this Lease by
lapse of time or otherwise, or upon termination of Tenant's right of possession
without termination of this Lease, Tenant shall surrender possession of the
Premises to Landlord and deliver all keys to the Premises to Landlord and make
known to Landlord the combination of all locks of vaults then remaining in the
Premises, and, subject to Section 8.02, shall return the Premises and all
equipment and fixtures of Landlord therein to Landlord in as good condition as
when Tenant originally took possession, ordinary wear, and damage resulting from
the act of Landlord or its employees and agents excepted, failing which Landlord
may restore the Premises and such equipment and fixtures to such condition and
Tenant shall pay the cost thereof to Landlord on demand.

     8.02 Installations and Additions. All installations, additions,
partitions, hardware, light fixtures, non-trade fixtures and improvements,
whether temporary or permanent, except movable furniture and equipment belonging
to Tenant, in or upon the Premises, whether placed there by Tenant or Landlord,
shall be Landlord's property and shall remain upon the Premises, all without
compensation, allowance or credit to Tenant; provided, however, that if prior to
such termination or within ten (10) days thereafter Landlord so directs by
notice, Tenant, at Tenant's sole cost and expense, shall promptly remove such of
the installations, additions, partitions, hardware, light fixtures, non-trade
fixtures and improvements placed in the Premises by Tenant as are designated in
such notice and repair any damage to the Premises caused by such removal,
failing which Landlord may remove the same and repair the Premises and Tenant
shall pay the 

                                      -15-
<PAGE>
 
cost thereof to Landlord on demand.

     8.03 Trade Fixtures and Personal Property. Tenant also shall remove
Tenant's furniture, machinery, safes, trade fixtures and other items of movable
personal property of every kind and description from the Premises and restore
any damage to the Premises caused thereby, such removal and restoration to be
performed prior to the end of the Term or within ten (10) days following
termination of this Lease or Tenant's right of possession, whichever is earlier.
If Tenant fails to remove such items, Landlord may do so and thereupon the
provisions of Section 17.06 shall apply and Tenant shall pay to Landlord upon
demand the cost of removal and of restoring the Premises.

     8.04 Survival. All obligations of Tenant under this Article shall
survive the expiration of the Term or earlier termination of this Lease.


                                   ARTICLE 9.
                                  HOLDING OVER

     Tenant shall pay Landlord for each day Tenant retains possession of the
Premises or any part thereof after termination of this Lease, by lapse of time
or otherwise, or of Tenant's right to possession of the Premises, an amount
which is double the amount of Base Rent and Rent Adjustments for a day based on
the annual rate of Base Rent set forth in Section 3.01 and on the Rent
Adjustments provided for in Article 4 in effect immediately prior to such
termination, and Tenant shall also pay all direct damages sustained by Landlord
by reason of such retention. Acceptance by Landlord of rent after such
termination, of itself, shall not constitute a renewal. Nothing contained in
this Section shall be construed or shall operate as a waiver of Landlord's right
of reentry or any other right or remedy of Landlord.


                                  ARTICLE 10.
                             RULES AND REGULATIONS

     Tenant agrees to observe and not to interfere with the rights reserved to
Landlord contained in Article 11 and agrees, for itself, its employees, agents,
contractors, invitees and licensees, to comply with the rules and regulations
set forth in Rider B attached to this Lease and made a part hereof and such
other rules and regulations as may be adopted by Landlord pursuant to Section
11.01(e) of this Lease. Any violation by Tenant of any of the rules and
regulations contained in Rider B or any other Section of this Lease, or as may
hereafter be adopted by Landlord pursuant to Section 11.01(e) of this Lease, may
be restrained; but whether or not so restrained, Tenant acknowledges and agrees
that it shall be and shall remain liable for all damages, loss, costs and
expenses resulting from any violation by Tenant of any of said rules and
regulations.

                          RIGHTS RESERVED TO LANDLORD

     11.01 Rights Reserved to Landlord. Landlord reserves the following
rights, exercisable without notice and without liability to Tenant for damage or
injury to property, person or business and without effecting an eviction or
disturbance of Tenant's use or possession or giving rise to any claim for setoff
or abatement of Rent or affecting any of Tenant's obligations under this Lease:

          (a) Except for portions of the Premises designated by Tenant as
"secured areas" on floor plans delivered to Landlord, to retain at all times,
and to use in appropriate instances, pass keys to the Premises;

          (b) Upon reasonable advance written or telephone notice, to exhibit
the Premises at reasonable hours, and to decorate, remodel, repair, alter or
otherwise prepare the Premises for reoccupancy at any time after Tenant vacates
or abandons the Premises;

          (c) To enter the Premises at reasonable hours, upon reasonable prior
notice and for reasonable purposes, including inspection, subject to Tenant's
reasonable security restrictions;

          (d) To make any repairs, alterations, improvements and additions in
and about the Building and the Premises during ordinary business hours and, if
Tenant desires to have such work done during other than business hours, Tenant
shall pay all overtime and additional expenses resulting therefrom; and

          (e) From time to time to make and adopt such reasonable rules and
regulations, in addition to or other than or by way of amendment or modification
of the rules and regulations contained in Rider B or other Sections of this
Lease, which are not inconsistent with the Terms of this Lease for the
protection and welfare of the Building as Landlord may determine, and Tenant
agrees to abide by and comply with all such rules and regulations.


                                  ARTICLE 12.
                                  ALTERATIONS

     Tenant shall not make, without the prior written consent of Landlord, any
alterations, additions or improvements to the Premises. Notwithstanding the
foregoing, Landlord's consent shall not be required for normal decorating work
such as painting and installation of wall coverings and carpeting.  Landlord
shall not unreasonably withhold or delay its consent to alterations, additions
or improvements to the Building which do not affect the exterior, or structural
portions of the Building or the base building mechanical, electrical, plumbing,
elevator, security or other systems in the Building. If Landlord consents to
such alterations, additions or improvements, before commencement of the work or
delivery of any materials onto the Premises or into the Building, Tenant shall
furnish to Landlord, for its approval, plans and 

                                      -17-
<PAGE>
 
specifications, names and addresses of contractors, copies of contracts,
necessary permits and licenses, and instruments of indemnification against any
and all claims, costs, expenses, damages and liabilities which may arise in
connection with such work, all in such form, substance and amount as may be
satisfactory to Landlord. In addition, prior to commencement of any such work or
delivery of any materials into the Premises, Tenant shall provide Landlord with
appropriate evidence of Tenant's ability to pay for such work and materials in
full. All alterations, additions and improvements shall be installed in a good,
workerlike manner and only new, high-grade materials shall be used. All such
work shall be done only by contractors or mechanics reasonably approved by
Landlord and shall be subject to Landlord's scheduling requirements and
regulations. Tenant further agrees to hold Landlord harmless from any and all
liabilities of every kind and description which may arise out of or be connected
in any way with said alterations, additions or improvements. Before commencing
any work in connection with such alterations, additions or improvements, Tenant
shall furnish Landlord with certificates of insurance from all contractors
performing labor or furnishing materials insuring Landlord against any and all
liabilities which may arise out of or may be connected in any way with said
alterations, additions or improvements. Tenant shall permit Landlord to
supervise construction operations in connection with the foregoing work if
Landlord requests to do so. Tenant shall pay the cost of all such alterations,
additions and improvements, as well as the cost of decorating the Premises
occasioned by such alterations, additions and improvements, including the cost
of labor and materials, contractors' profit, overhead, general conditions and a
reasonable fee to Landlord. Upon completing any alterations, additions or
improvements, Tenant shall furnish Landlord with (i) contractors' affidavits in
form required by law, and full and final waivers of lien and receipted bills
covering all labor and materials expended and used and (ii) "as built" or record
drawings showing all alterations, improvements and additions to the Premises.
All alterations, additions and improvements shall comply with all insurance
requirements and with all city and county ordinances and regulations and with
the requirements of all state and federal statutes and regulations.

                           ASSIGNMENT AND SUBLETTING

     13.01 Assignment and Subletting. Without the prior written consent of
Landlord in each instance and subject to Sections 13.08 and 13.09 below, Tenant
shall not (a) assign, transfer, mortgage, pledge, hypothecate or encumber or
subject to or permit to exist upon or be subjected to any lien or charge, this
Lease or any interest under it; (b) allow to exist or to occur any transfer of
or lien upon this Lease or Tenant's interest herein by operation of law; (c)
sublet the Premises or any part thereof; or (d) permit the use or occupancy of
the Premises or any part thereof for any purpose not provided for under Article
5 of this Lease or by anyone other than Tenant and Tenant's employees. Landlord
has the absolute right to withhold its consent without giving any reason
whatsoever, except as expressly provided herein to the contrary. In no event
shall this Lease be assigned or assignable by voluntary or involuntary
bankruptcy proceedings or otherwise, and in no event shall this Lease or any
rights or privileges hereunder be an asset of Tenant under any bankruptcy,
insolvency or reorganization proceedings.

                                      -18-
<PAGE>
 
     13.02 Rentals Based on Net Income. Without limiting the generality of
the foregoing provisions of this Article, Tenant expressly covenants and agrees
not to enter into any lease, sublease, license, concession or other agreement
for use, occupancy or utilization of the Premises which provides for rental or
other payment for such use, occupancy or utilization based in whole or in part
on the net income or profits derived by any person from the property leased,
used, occupied or utilized (other than an amount based on a fixed percentage or
percentages of receipts or sales), and that any such purported lease, sublease,
license, concession or other agreement shall be absolutely void and ineffective
as a conveyance of any right or interest in the possession, use, occupancy or
utilization of any part of the Premises.

      13.03 Tenant to Remain Obligated. Consent by Landlord to any
assignment, subletting, use, occupancy or transfer shall not operate to relieve
Tenant from any covenant or obligation hereunder except to the extent, if any,
expressly provided for in such consent, or be deemed to be a consent to or
relieve Tenant from obtaining Landlord's consent to any subsequent assignment,
transfer, lien, charge, subletting, use or occupancy. Tenant shall pay all of
Landlord's costs, charges and expenses, including reasonable attorneys' fees,
incurred in connection with any assignment, transfer, lien, charge, subletting,
use or occupancy made or requested by Tenant. Tenant agrees that all advertising
by Tenant or on Tenant's behalf with respect to the assignment of this Lease or
subletting of space must be approved in writing by Landlord prior to publication
which approval shall not be unreasonably withheld or delayed.

      13.04 Landlord's Consent. Tenant shall advise Landlord, by written notice
("Tenant Notice"), of its intention from, on and after a stated date (which
shall not be less than sixty (60) days after the date of Tenant's notice) to
assign this Lease or to sublet any part or all of the Premises for any part of
the Term. Tenant's notice shall state the name and address of the proposed
subtenant or assignee, and a true and complete copy of the proposed sublease or
assignment and sufficient information to permit Landlord to determine the
financial responsibility and character of the proposed subtenant or assignee
shall be delivered to Landlord with said notice. Landlord will not withhold its
consent unreasonably to Tenant's assignment of this Lease or Tenant's subletting
the space covered by its notice. Landlord shall not be deemed to have withheld
its consent unreasonably to a sublease of part or all of the Premises or an
assignment of this Lease if its consent is withheld because: (a) Tenant is then
in Default hereunder; (b) any notice of termination of this Lease or termination
of Tenant's possession is given under Article 17; (c) the portion of the
Premises which Tenant proposes to sublease, including the means of ingress
thereto and egress therefrom and the proposed use thereof, and the remaining
portion of the Premises will violate any city, state or federal law, ordinance
or regulation, including, without limitation, any applicable building code or
zoning ordinances; (d) the proposed use of the Premises by the subtenant or
assignee does not conform with the use permitted by Article 5; (e) in the
reasonable judgment of Landlord, the proposed subtenant or assignee is of a
character or is engaged in a business which would be deleterious to the
reputation of the Building, or the subtenant or assignee is not sufficiently
financially responsible to perform its obligations under the proposed sublease
or assignment; (f) the sublessee's or assignee's business is likely to cause
greater wear and tear to the Premises than occasioned by Tenant's use or (g) the
proposed subtenant or assignee is a government or a government agency; provided,
however, that the foregoing are merely examples of reasons for which Landlord
may withhold its consent
                                      -19-
<PAGE>

 
and shall not be deemed exclusive of any permitted reasons for reasonably
withholding consent, whether similar to or dissimilar from to the foregoing
examples. Landlord shall either approve or disapprove a proposed assignment or
sublease within thirty (30) days after receipt of the information and documents
described in the second sentence of this Section 13.04.

     13.05 Profits. If Tenant, having first obtained Landlord's consent to
any sublease or assignment, or if Tenant or a trustee in bankruptcy for Tenant
pursuant to the Bankruptcy Code, assigns this Lease or sublets the Premises, or
any part thereof, at a rental or for other consideration in excess of the Rent
or pro rata portion thereof due and payable by Tenant under this Lease, then
Tenant shall pay to Landlord as additional rent fifty percent (50%) of any such
excess rent or other monetary consideration immediately upon receipt under any
such assignment or, in the case of a sublease, (a) on the first day of each
month during the term of any sublease the excess of all rent and other
consideration due from the subtenant for such month over the Rent then payable
to Landlord pursuant to the provisions of this Lease for said month (or if only
a portion of the Premises is being sublet, the excess of all rent and other
consideration due from the subtenant for such month over the portion of the Rent
then payable to Landlord pursuant to the provisions of this Lease for said month
which is allocable on a square footage basis to the space sublet) and (b)
immediately upon receipt thereof, any other consideration realized by Tenant
from such subletting; it being agreed, however, that Landlord shall not be
responsible for any deficiency if Tenant assigns this Lease or sublets the
Premises or any part thereof at a rental less than that provided for herein.
Notwithstanding the foregoing, Tenant shall not be required to pay Landlord any
amounts pursuant to this Section 13.05 until the amount of the excess rent and
other consideration received by Tenant equals the reasonable out of pocket costs
incurred by Tenant in entering into such sublease or assignment including
without limitation brokers' and attorneys' fees, advertising costs, tenant
buildout costs and construction allowances.  The provisions of this Section
13.05 shall not apply to an assignment or sublease described in Sections 13.08
or 13.09 which does not require Landlord's consent.

permitted herein, the assignee shall expressly assume all of the obligations of
Tenant hereunder in a written instrument satisfactory to Landlord and furnished
to Landlord not later than fifteen (15) days prior to the effective date of the

Lease and shall be subject to the provisions of this Article 13. The term
"control" as used herein means the power, directly or indirectly, to direct or
to cause the direction of the management or policies of Tenant.

                 WAIVER OF CERTAIN CLAIMS; INDEMNITY BY TENANT

          14.01  Waiver of Certain Claims; Indemnity by Tenant. To the extent
not prohibited expressly by law, Tenant releases Landlord and its beneficiaries,
if any, and their agents, servants and employees, from and waives all claims for
damages to person or property sustained by Tenant or by any occupant of the
Premises or the Building, or by any other person, resulting directly or
indirectly from fire or other casualty, cause or any existing or future
condition, defect, matter or thing in or about the Premises, the Building or any
part of it, or from any equipment or appurtenance therein, or from any accident
in or about the Building, or from any act or neglect of any tenant or other
occupant of the Building or any part thereof or of any other person. This
Section shall apply especially, but not exclusively, to damage caused by water,
snow, frost, steam, excessive heat or cold, sewerage, gas, odors or noise, or
the bursting or leaking of pipes or plumbing fixtures, broken glass, sprinkling
or air conditioning devices or equipment, or flooding of basements, and shall
apply without distinction as to the person whose act or neglect was responsible
for the damage and whether the damage was due to any of the acts specifically
enumerated above, or from any other thing or circumstance, whether of a like
nature or of a wholly different nature.  Subject to Section 21.01 nothing in
this Section or in Section 14.03 shall release Landlord from liability for its
negligence or the negligence of its agents and employees.

          14.02  Damage Caused by Tenant's Neglect. If any damage to the
Premises or the Building or any equipment or appurtenance therein, whether
belonging to Landlord or to other tenants or occupants of the Building, results
from any act or neglect of Tenant, its employees, agents, contractors, licensees
or invitees, Tenant shall be liable therefor and if such damage is not repaired
within thirty (30) days after written notice from Landlord, Landlord may repair
such damage at its option and Tenant shall reimburse Landlord, upon demand by
Landlord, for all costs of such repairs and damages in excess of amounts, if
any, paid to Landlord under insurance covering such damage.

          14.03  Tenant Responsible for Personal Property. All personal property
belonging to Tenant or any occupant of the Premises that is in the Building or
the Premises shall be there at the risk of Tenant or other person only and
Landlord shall not be liable for damage thereto or theft or misappropriation
thereof.

          14.04  Indemnification.

          (a) To the extent not prohibited expressly by law, Tenant agrees to
hold Landlord and its beneficiaries, if any, and their officers, agents,
servants and employees, harmless and to indemnify each of them against claims
and liabilities, including reasonable attorneys' fees, for injuries to all
persons and damage to or theft or misappropriation or loss of property occurring
in or about the Premises arising from Tenant's occupancy of the Premises or the
conduct of its business or from any activity, work, or thing done, permitted or
suffered by Tenant in or about the Premises or from any breach or default on the
part of Tenant in the performance of any covenant or agreement on the part of
Tenant to be performed pursuant to 

                                     -23-
<PAGE>
 
the terms of this Lease or due to any other act or omission of Tenant, its
agents, contractors, invitees, licensees or employees, but only to the extent of
Landlord's liability, if any, in excess of amounts, if any, paid to Landlord
under insurance covering such claims or liabilities.

          (b) To the extent not prohibited expressly by law, Landlord agrees to
hold Tenant and its officers, agents, servants and employees, harmless and to
indemnify each of them against claims and liabilities, including reasonable
attorneys' fees, for injuries to all persons and damage to or theft or
misappropriation or loss of property occurring in or about the Premises arising
from the negligent acts of Landlord or its beneficiary or their employees,
agents or servants, or from any breach or default on the part of Landlord in the
performance of any covenant or agreement on the part of Landlord to be performed
pursuant to the terms of this Lease or due to any other act or omission of
Landlord or its beneficiaries or their agents, contractors, licensees or
employees, but only to the extent of Tenant's liability, if any, in excess of
amounts, if any, paid to Tenant under insurance covering such claims or
liabilities.

                                  ARTICLE 15.
                       DAMAGE OR DESTRUCTION BY CASUALTY

          15.01  Tenant's Obligation to Rebuild.  In the event of damage to, or
destruction of, any improvements on the Premises, or of the fixtures and
equipment therein, by fire or other casualty, Tenant shall promptly, at its
expense, repair, restore or rebuild to the extent possible to the same design,
plans and specifications as existed prior to the casualty. Rent shall not be
reduced or abated during the period of such repair, restoration or rebuilding
even if the improvements are not tenantable.

          15.02  Preconditions to Rebuilding.  Before Tenant commences such
repairing, restoration or rebuilding involving an estimated cost of more than
Fifty Thousand Dollars ($50,000.00), plans and specifications therefor, prepared
by a licensed architect satisfactory to Landlord shall be submitted to Landlord
for approval and Tenant shall furnish to Landlord (a) an estimate of the cost of
the proposed work, certified to by said architect; (b) satisfactory evidence of
sufficient contractor's comprehensive general liability insurance covering
Landlord, builder's risk insurance, and workmen's compensation insurance; and
(c) such other security as Landlord may require to insure payment for the
completion of all work free and clear of liens.  Landlord's approval of the
plans and specifications shall not be unreasonably withheld if such plans and
specifications comply with the provisions of Section 15.01.

          15.03  Payment for Rebuilding.  All sums arising by reason of loss
under the insurance referred to in Section 21.02(c) shall be deposited with the
Depository pursuant to Section 15.06, and Tenant shall deposit with the
Depository any excess cost of the work over the amount held by the Depository as
proceeds of the insurance within thirty (30) days from the date of the
determination of the cost of the work by the architect in accordance with
Section 15.02.  Tenant shall diligently pursue the repair or rebuilding of the
improvements in a good and workmanlike manner, using only high quality workmen
and materials.  The Depository shall pay out construction funds from time to
time on the written direction of the architect, after making

                                      -24-
<PAGE>
 
provision for a reasonable holdback, for the purpose of completing such repair
or rebuilding and upon receipt of appropriate contractors' statements, with
supporting affidavits and lien waivers. Notwithstanding the foregoing, if the
cost of the repair or restoration is less than $50,000, all proceeds of
insurance shall be paid to Tenant in trust to be used for restoration and repair
of such damage.

          15.04  Excess Insurance Proceeds.  Any excess of money received from
insurance remaining with the Depository after the repair or rebuilding of
improvements, if there is no default by Tenant in the performance of the
Tenant's covenants and agreements hereunder, shall be paid to Tenant; otherwise
said monies shall be paid to Landlord.  If this Lease shall be terminated
pursuant to Section 15.05, all insurance proceeds shall be paid to Landlord.

          15.05  Failure to Rebuild.  If (i) Tenant shall not enter upon the
repair or rebuilding of the improvements within a period of ninety (90) days
after the insurance proceeds are made available pursuant to Section 15.03 or
(ii) after commencement of such repair or rebuilding, Tenant does not prosecute
the same thereafter with such dispatch as may be necessary to complete the same
within a reasonable period after said damage or destruction occurs, and the
repair and rebuilding is not completed within one year from the date the
insurance proceeds are made available pursuant to Section 15.03, then, in
addition to  whatever other remedies Landlord may have either under this Lease,
at law or in equity, Landlord may retain the insurance proceeds, or the balance
thereof remaining in the hands of the Depository as security for the continued
performance and observance by Tenant of the Tenant's covenants and agreements
hereunder, or Landlord may terminate this Lease or Tenant's possession of the
Premises and then retain the amount so held as damages resulting from the
failure on the part of Tenant to comply with the provisions of this Article.

          15.06  Deposits.  All insurance proceeds, condemnation awards and
amounts deposited by Tenant ("Net Proceeds") shall be deposited with a bank or
other financial institution designated by the First Mortgagee or, if there is no
First Mortgage, by Tenant (the "Depository").  Tenant may direct the investment
of the amounts so deposited with the Depository in the following:

          (a) repurchase obligations of the Depository at all times fully
secured by direct and general obligations of the United States of America or
obligations guaranteed as to principal and interest by the United States of
America;

          (b) direct and general obligations of the United States of America or
obligations guaranteed as to principal and interest by the United States of
America purchased at a price not more than par;

          (c) certificates of deposit of the Depository at all times secured as
provided by applicable law; or

                                     -25-
<PAGE>
 
          (d) commercial paper which is rated "A-1" or better (or comparable
ratings) by Standard & Poor's Corporation or "P-1" or better (or comparable
ratings) by Moody's Investors Service, Inc., or the successors to such rating
organizations.

          Such investments of such funds shall mature in such amounts and on
such dates as to provide that amounts shall be available on the draw dates
sufficient to pay the amounts requested, and due to, Landlord or Tenant as the
case may be.  The Depository shall not be liable for any loss resulting from the
liquidation of each and every such investment.  The terms and conditions
relating to such deposit and investments shall otherwise be satisfactory to
Landlord, Tenant and the Depository.  All interest or other earnings net of
investment fees of the Depository shall be added to and deemed to be part of Net
Proceeds.

                                  ARTICLE 16.
                                 EMINENT DOMAIN

          16.01  Whole Taking.  If the entire Building or a substantial part
thereof is taken or condemned by any competent authority for any public or
quasi-public use or purpose, the Term of this Lease shall end upon and not
before the earlier of the date when the possession of the part so taken is
required for such use or purpose or the effective date of the taking, and
without apportionment of the award to or for the benefit of Tenant. If any
condemnation proceeding is instituted in which it is sought to take or damage
any part of the Building, the taking of which, in Landlord's opinion, would
prevent the economical operation of the Building, or if the grade of any street
or alley adjacent to the Building is changed by any competent authority, and
such taking, damage or change of grade makes it necessary or desirable to
remodel the Building to conform to the taking, damage or changed grade, Landlord
shall have the right to terminate this Lease upon not less than ninety (90)
days' notice prior to the date of termination designated in the notice. In
either of these events, Rent at the then current rate shall be apportioned as of
the date of the termination. No money or other consideration shall be payable by
Landlord to Tenant for the right of termination, and Tenant shall have no right
to share in the condemnation award, whether for a total or partial taking, for
loss of Tenant's leasehold or improvements or other loss or expenses or in any
judgment for damages caused by the change of grade. Tenant may however file a
separate claim for relocation expenses and for any of Tenant's personal property
taken, provided such claim does not reduce Landlord's award.

          16.02  Partial Taking.  If only a part of the Premises shall be so
taken or condemned, and as a result thereof the balance of the Premises can be
used for the same purpose as prior to such taking, this Lease shall not
terminate and Tenant, at its sole cost and expense, shall repair and restore the
Premises and all improvements thereon to the extent of the condemnation award.
Tenant shall promptly and diligently proceed to make a complete architectural
unit of the remainder of the improvements first complying with the procedure set
forth in Section 15.02.  The amount of the award relating to the improvements
and shall be held and disbursed in accordance with the procedure set forth in
Sections 15.03 and 15.06.  If Tenant does not make a complete architectural unit
of the remainder of the improvements within a reasonable period after such
taking or condemnation, not to exceed three hundred sixty five (365) days, then,
in

                                     -26-
<PAGE>
 
addition to whatever other remedies Landlord may have either under this Lease,
at law or in equity, Landlord may receive the entire award or the balance
thereof remaining in the custody of the Depository, as the case may be, as
liquidated damages resulting from the failure of Tenant to comply with the
provisions of this Section. Any portion of such award as may not have to be
expended for such repairing or restoration shall be paid to Landlord. There
shall be no abatement or reduction in any rental because of such taking or
condemnation unless a portion of the Building is taken in which event Base Rent
shall abate based on the percentage of the rentable space in the Building so
taken and not replaced pursuant to this Section.


                                  ARTICLE 17.
                                    DEFAULT

          17.01  Events of Default. The occurrence of any one or more of the
following matters constitutes a Default by Tenant under this Lease:

          (a) Failure by Tenant to pay any Rent when due if such failure
continues for ten (10) days after notice from Landlord of such failure;

          (b) Failure by Tenant to pay when due any other moneys required to be
paid by Tenant under this Lease if such failure continues for ten (10) days
after notice from Landlord of such failure;

          (c) Failure by Tenant to cure, immediately after receipt of notice
from Landlord, any hazardous condition which Tenant has created in violation of
law or of this Lease;

          (d) Failure by Tenant to observe or to perform any other covenant,
agreement, condition or provision of this Lease, if such failure continues for
thirty (30) days after notice thereof from Landlord to Tenant;

          (e) The levy upon, under writ of execution or the attachment by legal
process of, the leasehold interest of Tenant, or the filing or creation of a
lien with respect to such leasehold interest, which lien shall not be released
or discharged within ten (10) days from the date of such filing;

          (f) Tenant vacates or abandons the Premises or fails to take
possession of the Premises when available for occupancy (the transfer of a
substantial part of the operations, business and personnel of Tenant to some
other location being deemed, without limiting the meaning of the term, "vacates
or abandons," to be a vacation or abandonment within the meaning of this clause
(h) unless Tenant posts a full-time security guard at the Premises), whether or
not Tenant thereafter continues to pay Rent due under this Lease;

                                     -27-
<PAGE>
 
          (g) Tenant becomes insolvent or bankrupt or admits in writing its
inability to pay its debts as they mature, or makes an assignment for the
benefit of creditors, or applies for or consents to the appointment of a trustee
or receiver for Tenant or for the major part of its property;

          (h) A trustee or receiver is appointed for Tenant or for the major
part of its property and is not discharged within sixty (60) days after such
appointment;

          (i) Any bankruptcy, reorganization, arrangement, insolvency or
liquidation proceedings, or other proceedings for relief under any bankruptcy
law, or similar law for the relief of debtors, are instituted (i) by Tenant or
(ii) against Tenant and are allowed against it or are consented to by it or are
not dismissed within sixty (60) days after such institution; or

          (j) A Default occurs under the 3333 Lease.

          17.02  Rights and Remedies of Landlord. If a Default occurs, Landlord
shall have the rights and remedies hereinafter set forth, which shall be
distinct, separate and cumulative and which shall not operate to exclude or
deprive Landlord of any other right or remedy allowed it by law:
 
          (a) Landlord may terminate this Lease by giving to Tenant notice of
Landlord's election to do so, in which event the Term of this Lease shall end,
and all rights, title and interest of Tenant hereunder shall expire, on the date
stated in such notice;

          (b) Landlord may terminate the right of Tenant to possession of the
Premises without terminating this Lease by giving notice to Tenant that Tenant's
right of possession shall end on the date stated in such notice, whereupon the
right of Tenant to possession of the Premises or any part thereof shall cease on
the date stated in such notice; and

          (c) Landlord may enforce the provisions of this Lease and may enforce
and protect the rights of Landlord hereunder by a suit or suits in equity or at
law for the specific performance of any covenant or agreement contained herein,
or for the enforcement of any other appropriate legal or equitable remedy,
including recovery of all moneys due or to become due from Tenant under any of
the provisions of this Lease.

          17.03  Right to Re-Enter. If Landlord exercises either of the remedies
provided in Sections 17.02(a) or (b), Tenant shall surrender possession and
vacate the Premises and shall deliver immediately possession thereof to
Landlord, and Landlord may re-enter and take complete and peaceful possession of
the Premises, with process of law, full and complete license to do so being
hereby granted to Landlord, and Landlord may remove all occupants and property
therefrom, using such force as may be necessary, without being deemed guilty in
any manner of trespass, eviction or forcible entry and detainer and without
relinquishing Landlord's right to rent or any other right given to Landlord
hereunder or by operation of law.

                                     -28-
<PAGE>
 
          17.04  Current Damages. If Landlord terminates the right of Tenant to
possession of the Premises without terminating this Lease, Landlord shall have
the right to immediate recovery of all amounts then due hereunder. Such
termination of possession shall not release Tenant, in whole or in part, from
Tenant's obligation to pay the Rent hereunder for the full Term, and Landlord
shall have the right, from time to time, to recover from Tenant, and Tenant
shall remain liable for, all Base Rent, Rent Adjustments and any other sums
accruing as they become due under this Lease during the period from the date of
such notice of termination of possession to the stated end of the Term. In any
such case, Landlord shall use diligent efforts to mitigate its damages and to
relet the Premises or any part thereof for the account of Tenant for such rent,
for such time (which may be for a term extending beyond the Term of this Lease)
and upon such terms as Landlord shall determine and collect the rents from such
reletting. Landlord shall not be required to accept any tenant offered by Tenant
or to observe any instructions given by Tenant relative to such reletting. Also,
in any such case, Landlord may make repairs, alterations and additions in or to
the Premises and redecorate the same to the extent reasonably deemed by Landlord
necessary or desirable and in connection therewith change the locks to the
Premises, and Tenant shall pay upon demand the cost of all the foregoing
together with Landlord's expenses of reletting. The rents from any such
reletting shall be applied first to the payment of the expenses of reentry,
redecoration, repair and alterations and the expenses of reletting and second to
the payment of Rent herein provided to be paid by Tenant. Any excess or residue
shall operate only as an offsetting credit against the amount of Rent due and
owing as the same thereafter becomes due and payable hereunder, and the use of
such offsetting credit to reduce the amount of Rent due Landlord, if any, shall
not be deemed to give Tenant any right, title or interest in or to such excess
or residue and any such excess or residue shall belong to Landlord solely, and
in no event shall Tenant be entitled to a credit on its indebtedness to Landlord
in excess of the aggregate sum, including Base Rent and Rent Adjustments, which
would have been paid by Tenant for the period for which the credit to Tenant is
being determined, had no Default occurred. No such reentry or repossession,
repairs, alterations and additions, or reletting shall be construed as an
eviction or ouster of Tenant or as an election on Landlord's part to terminate
this Lease, unless a written notice of such intention is given to Tenant, or
shall operate to release Tenant in whole or in part from any of Tenant's
obligations hereunder, and Landlord, at any time and from time to time, may sue
and recover judgment for any deficiencies from time to time remaining after the
application from time to time of the proceeds of any such reletting.

          17.05  Final Damages. If this Lease is terminated by Landlord as
provided in Section 17.02(a), Landlord shall be entitled to recover from Tenant
all Rent accrued and unpaid for the period up to and including such termination
date, as well as all other additional sums payable by Tenant, or for which
Tenant is liable or in respect of which Tenant has agreed to indemnify Landlord
under any of the provisions of this Lease, which may be then owing and unpaid,
and all reasonable costs and expenses, including court costs and attorneys' fees
incurred by Landlord in the enforcement of its rights and remedies hereunder,
and, in addition, Landlord shall be entitled to recover as damages for loss of
the bargain and not as a penalty the aggregate sum which at the time of such
termination represents the excess, if any, of the present value of the aggregate
rents which would have been payable after the termination date had this Lease
not been terminated, including, without limitation, Base Rent at the annual rate

remainder of the Term pursuant to Article 3 of this Lease, over the then present
value of the then aggregate fair rental value of the Premises for the balance of
the Term, such present worth to be computed in each case on the basis of a five
percent (5%) per annum discount from the respective dates upon which such
rentals would have been payable hereunder had this Lease not been terminated,
and (c) any damages in addition thereto, including reasonable attorneys' fees

option, shall be conclusively deemed to have been conveyed by Tenant to Landlord
as by bill of sale without further payment or credit by Landlord to Tenant.

                                 SUBORDINATION

     18.01  Subordination. Landlord intends to execute and deliver and may
execute and deliver hereafter from time to time a first mortgage or first trust
deed in the nature of a mortgage, both being hereinafter referred to as a "First
Mortgage," against the Land and Building or any interest therein. If requested
by the mortgagee or trustee under any First Mortgage (the "First Mortgagee"),
Tenant will either (a) subordinate its interest in this Lease to said First
Mortgage, and to any and all advances made thereunder and to the interest
thereon, and to all renewals, replacements, supplements, amendments,
modifications and extensions thereof, or (b) make certain of Tenant's rights and
interest in this Lease superior thereto; and Tenant will execute and deliver
such agreement or agreements promptly, as may be reasonably required by such
First Mortgagee; provided that, as a condition to subordinating its rights and
interests under this Lease to any mortgage or trust deed, Tenant shall be
entitled to require the First Mortgagee to enter into a non-disturbance and
attornment agreement with Tenant, which agreement shall be in said holder's
standard form not inconsistent with this Lease. Tenant covenants it will not
subordinate this Lease to any mortgage or trust deed other than a First Mortgage
without the prior written consent of the First Mortgagee.

     18.02  Liability of Holder of First Mortgage; Attornment. It is further
agreed that (a) if any First Mortgage shall be foreclosed, (i) the First
Mortgagee, or purchaser at any foreclosure sale (or grantee in a deed in lieu of
foreclosure), as the case may be, shall not be (x) liable for any act or
omission of any prior landlord (including Landlord), (y) subject to any offsets
or counterclaims which Tenant may have against a prior landlord (including
Landlord), or (z) bound by any prepayment of Base Rent or Rent Adjustments which
Tenant may have made in excess of the amounts then due for the next succeeding
month, (ii) the liability of the First Mortgagee or purchaser at such
foreclosure sale or the liability of a subsequent owner designated as Landlord
under this Lease shall exist only so long as such trustee, mortgagee, purchaser
or owner is the owner of the Building or Land and such liability shall not
continue or survive after further transfer of ownership; and (iii) upon request
of the First Mortgagee, if the First Mortgage is foreclosed, Tenant will attorn,
as Tenant under this Lease, to the purchaser at any foreclosure sale under any
First Mortgage, and Tenant will execute such instruments as may be necessary or
appropriate to evidence such attornment; and (b) this Lease may not be modified
or amended so as to reduce Rent or shorten the Term provided hereunder, or so as
to affect adversely in any other respect to any material extent the rights of
Landlord, and this Lease shall not be cancelled or surrendered, without the
prior written consent, in each instance, of any First Mortgagee.

     18.03  Modification Required by First Mortgagee. Should any prospective
First Mortgagee require a modification or modifications of this Lease, which
modification or modifications will not cause an increased cost or expense to
Tenant or in any other way materially change the rights and obligations of
Tenant hereunder, Tenant agrees that this Lease may be so modified and agrees to
execute whatever documents are required therefor and deliver the same to
Landlord within ten (10) days following the request therefor.

     18.04  Short Form Lease. Should any prospective First Mortgagee require
execution of a short form of lease for recording (containing the names of the
parties, a description of the Premises, and the term of this Lease) or a
certification from Tenant concerning this Lease in such form as may be required
by a prospective mortgagee, Tenant agrees to promptly execute such short form of
lease or certificate and deliver the same to Landlord within ten (10) days
following the request therefor.

                             MORTGAGEE PROTECTION

     Tenant agrees to give any First Mortgagee, by registered or certified mail,
a copy of any notice or claim of default served upon Landlord by Tenant,
provided that prior to such notice, Tenant has been notified in writing, by way
of service on Tenant of a copy of an assignment of Landlord's interests in
leases, or otherwise, of the address of such First Mortgagee. Tenant further
agrees that if Landlord has failed to cure such default within twenty (20) days
after such notice to Landlord (or if such default cannot be cured or corrected
within that time, then such additional time as may be necessary if Landlord has
commenced within such twenty (20) days and is pursuing diligently the remedies
or steps necessary to cure or correct such default), then the First Mortgagee
shall have an additional thirty (30) days within which to cure or correct such
default (or if such default cannot be cured or corrected within that time, then
such additional time as may be necessary if the First Mortgagee has commenced
within such thirty (30) days and is pursuing diligently the remedies or steps
necessary to cure or correct such default, including the time necessary to
obtain possession if possession is necessary to cure or correct such default).

hereto as Rider D. Tenant agrees that from time to time upon not less than ten
(10) days' prior request by Landlord, or any First Mortgagee or any ground
lessor, Tenant (or any permitted assignee, subtenant, licensee, concessionaire
or other occupant of the Premises claiming by, through or under Tenant) will
deliver to Landlord or to any First Mortgagee or ground lessor, a statement in
writing signed by Tenant certifying (a) that this Lease is unmodified and in
full force and effect (or if there have been modifications, that this Lease as
modified is in full force and effect and identifying the modifications); (b) the

otherwise, pending against Tenant under the bankruptcy laws of the United States
or any State thereof; and (g) such other matters as may be reasonably required

                                  ARTICLE 21.
                           SUBROGATION AND INSURANCE

     21.01  Waiver of Subrogation. Landlord and Tenant agree to have all "all-
risk" coverage and other property damage insurance and any rent loss or business
interruption insurance which may be carried by either of them endorsed with a
clause providing that any release from liability of or waiver of claim for
recovery from the other party entered into in writing by the insured thereunder
prior to any loss or damage shall not affect the validity of said policy or the
right of the insured to recover thereunder and providing further that the
insurer waives all rights of subrogation which such insurer might have against
the other party. Without limiting any release or waiver of liability or recovery
set forth elsewhere in this Lease, and notwithstanding anything in this Lease
which may appear to be to the contrary, each of the parties hereto waives all
claims for recovery from the other party for any loss or damage to any of its
property insured under valid and collectible insurance policies to the extent of
any recovery collectible under such insurance policies. Notwithstanding the
foregoing or anything contained in this Lease to the contrary, any release or
any waiver of claims shall not be operative, and the foregoing endorsements
shall not be required, in any case where the effect of such release or waiver is
to invalidate insurance coverage or invalidate the right of the insured to
recover thereunder or increase the cost thereof (provided that in the case of
increased cost the other party shall have the right, within ten (10) days
following written notice, to pay such increased cost keeping such release or
waiver in full force and effect).

     21.02  Tenant's Insurance. Tenant shall carry insurance during the entire
Term hereof with terms, coverages and in companies satisfactory to Landlord and
with such increases in limits as Landlord may request from time to time, but
initially Tenant shall maintain the following coverages in the following
amounts:

          (a) Comprehensive or commercial general liability insurance, including
     contractual liability, on an occurrence basis, in an amount not less than
     Fifteen Million Dollars ($15,000,000.00) combined single limit per
     occurrence, covering Tenant, Landlord and its beneficiaries as a named
     insured and Landlord's mortgagee as an additional insured.

          (b) Insurance against fire, sprinkler leakage, vandalism and the
     extended coverage perils for the full replacement cost of all additions,
     improvements and alterations to the Premises owned or made by Tenant, if
     any, and of all office furniture, trade fixtures, office equipment,
     merchandise and all other items of Tenant's property on the Premises, with
     loss or damage payable to Landlord and Tenant as their interests may
     appear.

                                      -33-
<PAGE>
 
          (c) Standard Fire and Extended Coverage Policy and all other risks of
     direct physical loss as insured against under Special Extended Coverage
     Endorsement, insuring the improvements at any time situated upon the
     Premises against loss or damage by fire, lightning, wind storm, hail storm,
     aircraft, vehicles, smoke, explosion, riot or civil commotion. The
     insurance coverage shall be for not less than 100% of the full replacement
     cost of such improvement with all proceeds of insurance payable to
     Landlord. Landlord shall be a named insured on such policies. The insurance
     shall include standard mortgagee loss payable clauses for benefit of
     Landlord's Mortgagee. The full replacement cost of improvements shall be
     determined every five (5) years by an insurance appraiser selected by
     Tenant with Landlord's reasonable approval and paid for by Tenant or by
     other means reasonably acceptable to Landlord and its First Mortgagee. Any
     insurance appraiser hired by Tenant shall submit a written report of his
     appraisal to Landlord and Tenant and if said report shows that the
     improvements are not insured as herein required, Tenant shall promptly
     obtain such additional insurance as is required;

          (d) Boiler Insurance, insuring Landlord and Tenant with the same
     limits of coverage as provided in subsection (c) for loss or damage by
     boiler or internal explosion or break down of boilers;

          (e) Worker's Compensation Insurance, insuring Tenant from all worker's
     compensation claims;

          (f) Plate Glass Insurance, insuring Landlord and Tenant from damage to
     any plate glass on the Premises; and

          (g) Builders Risk Insurance insuring Landlord and Tenant against "all
     risks" including collapse and transit coverage during any construction of
     any improvements to or repair of the Premises after the Commencement Date
     covering the total value of work performed and equipment, supplies and
     material furnished.

          Such insurance shall be written by companies of nationally recognized
     financial standing, legally qualified to issue such insurance and accorded
     a rating by A.M. Best Company, Inc. of A:XII or higher at the time of
     issuance of any such policy. Each insurance policy carried by Tenant shall
     contain, where appropriate, a clause stating that such policy will be
     considered as primary insurance for Landlord and its agents and
     beneficiaries and not call into contribution any other insurance that may
     be available to Landlord. All insurance claims other than under Worker's
     Compensation and contents insurance pertaining to the Premises in amounts
     of $25,000 or less shall be adjusted by the insurer with Tenant, and all
     claims in excess of $25,000 shall be adjusted by Landlord and Tenant
     jointly.

     21.03  Certificates of Insurance. Tenant shall furnish to Landlord, prior
to the commencement of the Term and at least thirty (30) days prior to the
expiration of any such policies, policies or certificates evidencing such
coverage, which policies or certificates shall

                                      -34-
<PAGE>
 
state that such insurance coverage may not be reduced, cancelled or not renewed
without at least thirty (30) days' prior written notice to Landlord and Tenant
(unless such cancellation is due to nonpayment of premium, and in that case,
only ten (10) days' prior written notice shall be sufficient).

     21.04  Compliance with Requirements. Tenant shall comply with all
applicable laws and ordinances, all orders and decrees of court and all
requirements of other governmental authorities, and shall not make any use of
the Premises, directly or indirectly, which may be prohibited thereby, which may
be dangerous to person or property, which may jeopardize any insurance coverage,
or which may increase the cost of insurance or require additional insurance
coverage.

                                  ARTICLE 22.
                                   NONWAIVER

     No waiver of any condition expressed in this Lease shall be implied by any
neglect of Landlord to enforce any remedy on account of the violation of such
condition whether or not such violation is continued or repeated subsequently,
and no express waiver shall affect any condition other than the one specified in
such waiver and that one only for the time and in the manner specifically
stated. Without limiting Landlord's rights under Article 9, it is agreed that no
receipt of moneys by Landlord from Tenant after the termination in any way of
the Term or of Tenant's right of possession hereunder or after the giving of any
notice shall reinstate, continue or extend the Term or affect any notice given
to Tenant prior to the receipt of such moneys. It is also agreed that after the
service of notice or the commencement of a suit or after final judgment for
possession of the Premises, Landlord may receive and collect any moneys due, and
the payment of said moneys shall not waive or affect said notice, suit or
judgment.

                                  ARTICLE 23.
                               TENANT'S AUTHORITY

     Tenant (a) represents and warrants that this Lease has been duly
authorized, executed and delivered by and on behalf of Tenant and constitutes
the valid and binding agreement of Tenant in accordance with the terms hereof,
(b) if Landlord so requests, it shall deliver to Landlord or its agent,
concurrently with the delivery of this Lease executed by Tenant, certified
resolutions of the board of directors (and shareholders, if required)
authorizing Tenant's execution and delivery of this Lease and the performance of
Tenant's obligations hereunder, and (c) until Landlord is notified in writing of

Schedule shall have full power and authority to take action on behalf of and to
bind Tenant with respect to all matters relating to this Lease and the Premises.

and all reports, notifications, and other filings made by Tenant to any federal,
state, or local environmental authorities or agencies; and (v) any other

Environmental Laws relating to the Premises.

     26.06 Tenant's Obligation to Respond. If Tenant's Management of Hazardous

trespass, Tenant shall, at its sole cost and expense, promptly take all
applicable action in response so as to comply with all applicable Environmental
Laws and eliminate or avoid any liability claim with respect thereto.

     26.07 Landlord's Right to Act. In the event that Tenant shall fail to
comply with any of its obligations under this Article 26 as and when required
hereunder, Landlord shall have the right (but not the obligation) to take such
action as is required to be taken by Tenant hereunder and in such event, Tenant
shall be liable and responsible to Landlord for all costs, expenses,
liabilities, claims and other obligations paid, suffered, or incurred by
landlord in connection with such matters. Tenant shall reimburse Landlord
immediately upon demand for all such amounts for which Tenant is liable.

          the Term, are or were actually or allegedly Managed, generated,

          Hazardous Material are now or may in the future be located or disposed
          of), including but not limited to, any and all (1) liabilities under
          any common law theory of tort, nuisance, strict liability,
          ultrahazardous activity, negligence or otherwise based upon, resulting
          from or in connection with any Hazardous Material; (2) obligations to
          take Response, cleanup or corrective action pursuant to any
          investigation or remediation in connection with the decontamination,
          removal, transportation, incineration, or disposal of any of the
          foregoing; and

               (ii) any actual or alleged illness, disability, injury, or death
          of any person; in any manner arising out of or allegedly arisen out of
          exposure to Hazardous Materials or other substances or conditions
          present at the Building or Land, regardless of when any such illness,
          disability, injury, or death shall have occurred or been incurred or
          manifested itself; and

               (iii) any actual or alleged failure of Tenant or the Building or
          Land at any time and from time to time to comply with all applicable
          Environmental Laws, whether before or after the effective date of this
          Lease; and

               (iv) any failure by Tenant to comply with its obligations under
          this Article 26.

     In the event any Claims or other assertion of liability shall be made
against Landlord for which Landlord is entitled to indemnity hereunder, Landlord
shall notify Tenant of such Claim or assertion of liability and thereupon Tenant
shall, at its sole cost and expense, assume the defense of such Claim or
assertion of liability and continue such defense at all times thereafter until
completion. The obligations of Tenant under this Article 26 shall survive any
termination or expiration of this Lease. Nothing herein shall require Tenant to
indemnify, defend or hold harmless Landlord from, and Landlord shall reimburse,
defend, indemnify and hold Tenant, its employees, officers, directors,
shareholders and agents free and harmless from and against any Environmental
Claims arising out of or in anyway connected with any Hazardous Materials
Managed or Released on the Premises by Landlord or its agents, contractors or
employees.

                       TITLE AND COVENANT AGAINST LIENS

     Landlord's title is and always shall be paramount to the title of Tenant
and nothing contained in this Lease shall empower Tenant to do any act which
can, shall or may encumber the title of Landlord. Tenant covenants and agrees
not to suffer or permit any lien of mechanics or materialmen to be placed upon
or against the Premises, the Building, the Land or against Tenant's leasehold
interest in the Premises and, in case of any such lien attaching, to pay and
remove same immediately. Tenant has no authority or power to cause or permit any
lien or encumbrance of any kind whatsoever, whether created by act of Tenant,
operation of law or otherwise, to attach to or to be placed upon the Premises,
the Building or the Land, and any and all liens and encumbrances created by
Tenant shall attach only to Tenant's interest in the Premises. If any such liens
so attach and Tenant fails to pay and remove or bond over the same within thirty
(30) days, Landlord, at its election, may pay and satisfy the same and in such
event the sums so paid by Landlord, with interest from the date of payment at
the rate set forth in Section 28.08 for amounts owed Landlord by Tenant. Such
sums shall be deemed to be additional rent due and payable by Tenant at once
without notice or demand.

until this instrument is signed and delivered by Landlord and Tenant; provided,
however, the execution and delivery by Tenant of this Lease to Landlord or the

                             EXCULPATORY PROVISIONS

anything herein to the contrary notwithstanding, that each and all of the

warranties, covenants, undertakings and agreements of Landlord, are nevertheless
each and every one of them made and intended, not as personal representations,

     If the annual Base Rent for any period described above cannot be determined
as of the first day of such period, then until such amount is determined, Tenant

of such amount within thirty (30) days thereafter and Tenant, in the case of an
underpayment, shall pay to Landlord any additional Base Rent due for the portion

overpayment, shall pay to Tenant the amount of such overpayment.

     If Tenant exercises its option to extend the Term for an Extended Term,
then within thirty (30) days after receipt of Tenant's notice exercising the
Extension Option (or, if later, eight (8) months prior to the end of the then
Term), Landlord shall notify Tenant of its determination of the Market Rent for
the Extended Term in question. If the Market Rent determined by Landlord is
greater than the Base Rent determined pursuant to clause (2) of paragraphs

written notice ("Tenant's Rent Determination Notice") delivered to Landlord
either (i) to accept Landlord's determination of the Market Rent or (ii) to have
the Market Rent determined by appraisal pursuant to paragraph (c) below, in
which event Tenant shall also set forth its determination of the Market Rent. If
Tenant fails to timely deliver such notice, Tenant will be deemed to have
accepted Landlord's determination of the Market Rent.

(b)  As used in this Rider A and in the Lease:

     (i)    "CPI" shall mean the Revised Consumer Price Index for Urban Wage
            Earners and Clerical Workers, All Items (base index year 
            1982-84=100), for Chicago, Gary, Lake County, IL-IN-WI, as published
            by the United States Department of Labor, Bureau of Labor
            Statistics. If the manner in which the Consumer Price Index is
            determined by the Bureau of Labor Statistics shall be substantially
            revised, including, without limitation, a change in the base index
            year, a reasonable adjustment shall be made by Landlord in such
            revised index which would produce results equivalent, as nearly as
            possible, to those which would have been obtained if such Consumer
            Price Index had not been so revised. If the Consumer Price Index
            shall become unavailable to the public because publication is
            discontinued, or otherwise, or if equivalent data is not readily
            available to enable Landlord to make the adjustment referred to in
            the preceding sentence, then Landlord will substitute therefor a
            comparable index based upon changes in the cost of living or
            purchasing power of the consumer dollar published by any other
            governmental agency or, if no such index is available, then a
            comparable index published by a university, a major bank or other
            financial institution, or a comparable and recognized financial
            publication.

     (ii)   "Market Rent" shall mean the then prevailing market rental rate per
            rentable square foot of area for space comparable to the space to be
            leased by Tenant for the term of the lease of such space, taking
            into account applicable loss factors, applicable lengths of lease
            term, the creditworthiness of the tenants, differences in the size
            of the space leased, the then market rental conditions, the
            condition of the subject premises and comparable space, the location
            of amenities in the Building and comparable buildings, the fact that
            this Lease is a triple net lease, differences in operating expenses
            and taxes, Rent Concessions and other factors normally taken into
            account in determining fair market rent. As used herein, "Rent
            Concessions" means market rent credits or abatements, lease buy-outs
            or takeovers, the work letters and tenant improvement construction
            allowances provided under leases for comparable space and other
            market tenant inducement concessions. Market Rent shall be
            determined as a rate net of all Rent Concessions.

(c)  If the Market Rent is to be determined by appraisal, then:

     (i)    No later than fifteen (15) days following Tenant's Rent
            Determination Notice, Tenant shall select and retain an individual
            as an appraiser of its choice and give Landlord written notice of
            such appraiser's name, address and telephone number ("Tenant's
            Selection Notice").

                                      -3-

<PAGE>
 
     (ii)   Within twenty (20) days after receipt of Tenant's Selection Notice,
            Landlord shall select and retain an appraiser of its choice and give
            Tenant written notice of such appraiser's name, address and
            telephone number "(Landlord's Selection Notice").

     (iii)  The appraisers so selected by Tenant and Landlord shall then select
            an individual as a third appraiser within five (5) days after
            receipt by Tenant of Landlord's Selection Notice and furnish
            Landlord and Tenant written notice of such appraiser's name, address
            and telephone number and Landlord and Tenant shall retain the
            services of such third appraiser.

     (iv)   Within fifteen (15) days following selection of the appraisers,
            Landlord and Tenant shall each simultaneously submit to the other
            their respective determinations of the Market Rent. During the next
            seven (7) days both Landlord and Tenant shall prepare a written
            critique of the other's determination and on the seventh (7th) day
            Landlord's and Tenant's determinations (as previously submitted to
            the other party with no modifications or additions whatsoever) and
            Landlord's and Tenant's critiques shall be submitted to the
            appraisers.

     (v)    The three (3) appraisers shall then determine by majority vote
            whether the Market Rent submitted by Landlord or the Market Rent
            submitted by Tenant is the Market Rent for the Premises for the
            Extended Term in question.

     All appraisers selected pursuant to this paragraph shall have at least ten
     (10) years experience with commercial property in the area where the
     Premises are situated and have an MAI certification or be licensed leasing
     brokers based in Metropolitan Chicago, shall not have a financial interest
     in Landlord or Tenant and shall otherwise be impartial.

     If Tenant fails to appoint its appraiser in the manner and within the time
     specified in (i) above, then the Market Rent shall be the Market Rent
     determined by Landlord. If Landlord fails to appoint its appraiser in the
     manner and within the time prescribed in clause (ii), then such Market Rent
     shall be the Market Rent set forth in the Tenant's Rent Determination
     Notice.

     If the appraisers selected by Tenant and Landlord fail to appoint the third
     appraiser within the time and in the manner prescribed in clause (iii)
     above, then Landlord and Tenant shall jointly and promptly apply to the
     local office of the American Arbitration Association for the appointment of
     the third appraiser.

     The decision of the appraisers shall be binding, final and conclusive on
     the parties (unless it shall be manifest that the appraiser or one or more
     of the appraisers shall not be an impartial person) and shall be
     enforceable by either party in a court of competent jurisdiction. The cost
     of the foregoing appraisal process (including any court costs) shall be
     borne equally by the parties).

                         FIRST AMENDMENT TO 1501 LEASE
                         -----------------------------

    THIS AMENDMENT, made as of the 1st day of November, 1997, between BANK ONE,
ILLINOIS, N.A., not personally but solely as Trustee under Trust Agreement dated
May 23, 1997, and known as Trust No. 11097 ("Landlord") and MAY & SPEH, INC.
("Tenant").

                                   RECITALS

     Landlord and Tenant are parties to a written lease dated June 2, 1997,
("1501 Lease"), for the entire building ("1501 Building") located at 1501 Opus
Place, Downers Grove, Illinois. Section S.4 of the 1501 Lease grants Tenant
certain options to acquire the 1501 Building and the land thereunder; provided
that, Tenant also exercises the option to purchase the building ("3333
Building") to be constructed by Landlord and leased to Tenant on the land
commonly referred to as 3333 Finley Road, Downers Grove, Illinois pursuant to
the option granted in the lease between Landlord and Tenant also dated June 2,
1997 for the 3333 Building ("3333 Lease").

    The terms and conditions of Tenant's option to purchase the 1501 Building
are set forth in Rider E to the 1501 Lease and the terms and conditions of the
purchase of the 3333 Building are set forth in Rider E to the 3333 Lease. The
purchase price for the 1501 Building is set forth in Rider E to the 1501 Lease
and the purchase price for the 3333 Building is based on a formula which takes
into account the purchase price for the 1501 Building. Landlord and Tenant
desire to increase the purchase price for the 1501 Building and to make a
similar reduction to the purchase price of the 3333 Building to permit Landlord
to refinance the 1501 Building and to finance the construction of the 3333
Building. Landlord and Tenant have also agreed that Tenant will assume any
financing on the respective buildings if it exercises its option to purchase.

    Landlord and Tenant have agreed to modify the Base Building Improvements
under the 3333 Lease to include the construction of a tunnel ("Tunnel") from the
1501 Building to the 3333 Building and modify the Maximum Project Costs to take
into account the change in the Base Building Improvements. The portion of the
Tunnel on the Land is to be included in the Premises.

    Tenant is also constructing an approximate 15,000 square foot addition to
the Building for use as storage space ("Storage Addition").

          NOW, THEREFORE, in consideration of the mutual covenants and
conditions contained herein, the Lease is hereby amended as follows:

     1.   All capitalized terms used herein shall have the same meanings as in
the 1501 Lease unless otherwise defined herein.

    2.    Notwithstanding anything in the 1501 Lease to the contrary, the
Premises shall include the portion of the Tunnel located on the Land and the
Storage Addition and Tenant's obligations under this Lease with respect to the
Premises, including without limitation, its obligations to maintain and repair
the Premises, shall apply to the portion of the Tunnel included in the Premises
and the Storage Addition.

     3.   Section 3.1 of the Purchase Contract attached as Rider E to the 1501
Lease is amended in its entirety to read as follows:

                 3.1 PURCHASE PRICE. The purchase price ("Purchase Price") for
       the Property shall be Twelve Million Eight Hundred Thousand and 00/100
       Dollars ($12,800,000.00).

          Purchaser agrees to pay to Seller and Seller agrees to accept payment
       of the Purchase Price as follows:

                 (a) At Closing, Purchaser shall accept title to the Property
       subject to the lien of the First Mortgage (which Purchaser or its nominee
       or designee will take subject to, and with respect to which First
       Mortgage and the loan evidenced and secured thereby Purchaser or its
       nominee or designee shall assume), and the outstanding principal balance
       thereunder shall be credited against the Purchase Price.

                 (b) The remaining portion of the Purchase Price, subject to
       prorations and adjustments as provided in Section 8.1, shall be paid on
       the Closing Date by wire transfer of immediately available funds, first
       to the Title Company and then to an account specified by Seller, against
       delivery of instruments of transfer and the other documents specified in
       Section 7.1.

     4.   Except for the provisions of this Amendment, all the terms, covenants,
and conditions of the Lease and all the rights and obligations of Landlord and
Tenant thereunder, shall remain in full force and effect, and are not otherwise
altered, amended, revised or changed.

     5.   It is understood and agreed expressly by and between the parties
hereto, anything herein to the contrary notwithstanding, that each and all of
the representations, warranties, covenants, undertakings and agreements made
herein on the part of Landlord, while in form purporting to be the
representations, warranties, covenants, undertakings and agreements of Landlord,
are nevertheless each and every one of them made and intended, not as personal
representations, warranties, covenants, undertakings and agreements by Landlord
or for the purpose or with the intention of binding Landlord personally, but are
made and intended for the purpose only of subjecting Landlord's interest in the
Building, the Land and the Premises to the terms of this Lease and for no other
purpose whatsoever, and in case of default hereunder by Landlord (or default
through, under or by any of its beneficiaries, or agents or representatives of
said beneficiaries), Tenant shall look solely to the interests of Landlord in
the Building and Land; that this Lease is executed and delivered by Landlord not
in its own right, but solely in the exercise of the powers conferred upon it as
trustee; that neither Landlord nor any of Landlord's beneficiaries shall have
any personal liability to pay any indebtedness accruing hereunder or to perform
any covenant, either express or implied, contained herein and no liability or
duty shall rest upon Landlord to sequester the trust estate or the rents, issues
and profits arising therefrom, or the proceeds arising from any sale or other
disposition thereof; and that no personal liability or personal responsibility
of any sort is assumed by, nor at any time shall be asserted or enforceable
against, said Landlord, individually

                                      -2-

or personally, but only as trustee under the provisions of the trust agreement
establishing the trust, or against any of the beneficiaries under the trust
agreement establishing the trust on account of this Lease or on account of any
representation, warranty, covenant, undertaking or agreement of Landlord
contained in this Lease, either express or implied, all such personal liability,
if any, being expressly waived and released by Tenant and by all persons
claiming by, through or under Tenant.

     IN WITNESS WHEREOF, the parties have caused this Amendment to be executed
on the date first above written.

S.3  Vacant Space

     (a)  Landlord and Tenant acknowledge that even though the Premises includes
the entire Building, Tenant does not intend to initially occupy the second and
third floors ("Vacant Space") of the Building and the Office Improvements will
not include any construction on such floors. Additionally, prior to September 1,
2000, the annual Base Rent will not include any amount for the Vacant Space
unless Tenant occupies a portion of such floors for the conduct of its business.
Tenant shall notify Landlord in writing at least thirty (30) days prior to the
date Tenant intends to occupy any portion of the Vacant Space for the conduct of
its business (which shall not include use of such space for storage).

     (b)  All alterations, additions, improvements or modifications required for
Tenant's initial use of the Vacant Space ("Vacant Space Alterations") shall be

allowance ("Vacant Space Construction Allowance") of $1,250,000 to be applied to
the cost of the Vacant Space Alterations incurred by Tenant from time to time,
including without limitation, the cost to prepare the plans and specifications
for such work. When and as Tenant occupies portions of the Vacant Space for the
conduct of its business, Landlord shall pay a portion of the Vacant Space
Construction Allowance to Tenant. The portion payable to Tenant upon such
occupancy shall be the lesser of (i) the cost of the Vacant Space Alterations
for the portion of the space occupied by Tenant and (ii) $1,250,000 multiplied
by the decimal equivalent of the percentage of the Vacant Space occupied by
Tenant. Landlord shall pay such portion of the Vacant Space Construction
Allowance to Tenant in accordance with paragraph (c) below.

          (ii)   Except for the final draw, the maximum amount of any draw shall
     not exceed an amount which bears the same ratio to the portion of the
     Vacant Space Construction Allowance applicable to the space being improved
     by Tenant as the cost of the Vacant Space Alterations for such space paid
     by Tenant and covered by the lien waivers submitted by Tenant in connection
     with the draw request bears to the total cost of the Vacant Space
     Alterations for such space;

          (iii)  With each draw request Tenant shall submit to Landlord the
     following documents:

                 (A)  A true and correct copy of the application for payment by
          Tenant's contractors for Vacant Space Alterations for the space in

          space in question performed to date;

                 (B)  Partial or final lien waivers with respect to Vacant Space
          Alterations for the space in question performed to date;

                 (C)  Tenant's certification to Landlord that the amounts set
          forth in all Contractor's sworn statements are owed to Tenant's
          contractors for Vacant Space Alterations for the space in question
          performed to date;

                 (D)  The total cost of Vacant Space Alterations for the space
          in question based on the plans approved by Landlord, as such cost may
          change from time to time;

                 (E)  With the final draw request, Tenant shall submit to
          Landlord a certificate from Tenant's architect stating that Vacant
          Space Alterations for the space in question has been completed in
          accordance with the Plans approved by Landlord and applicable zoning,
          building, environmental and other laws.

          (iv)   Landlord will disburse the portion of the Vacant Space
     Construction Allowance allocable to each draw request to Tenant or Tenant's
     contractors (at Tenant's option) within thirty (30) days after Tenant has
     submitted the required information for such draw and has otherwise complied
     with the requirements hereof.

Lease to purchase the premises under such lease on the Closing Date defined

conditions set forth in the Purchase Contract.

     S.5  Development of Third Building Parcel.  Landlord shall have the right
to construct a building on the portion of the Land designated as the Third

the Third Building Parcel commencing prior to September 1, 2007. Upon the
commencement of any development by Landlord of the Third Building Parcel, the
Third Building Parcel shall be deleted from the Premises and Land for purposes
of this Lease, and Landlord shall provide Tenant with appropriate easements for
access to and use of any Replacement Spaces not located on the Land. If Tenant

2007, then Tenant's option to purchase the Premises under Section S.4 above

intent of the parties hereto that the Base Rent payable under this Lease shall

costs and expenses relating to the Premises and the business carried on therein,

          and Terms. If Landlord does not enter into said written agreement
          within said one hundred eighty (180) day period, or, if said agreement
          is entered into, Landlord does not close the sale within two hundred
          seventy (270) days after receipt of Tenant's notice, at a price and
          terms equal to or greater than Tenant's Price and terms, then Landlord
          may not sell the Premises without again giving Tenant notice of its
          desire to sell the Premises as required by Section S.7(c).

               (ii)   If Tenant gave or is deemed to have given the notice in
          Section S.7(c)(iii) then Landlord may enter into a written agreement
          to sell the Premises at any time during the one hundred eighty (180)
          day period after receipt of Tenant's notice or if no notice is given
          within two hundred forty (240) days after Landlord's Notice on any
          terms and conditions. If Landlord does not enter into said written
          agreement within said one hundred eighty (180) or two hundred forty
          (240) day period, or, if said agreement is entered into, Landlord does
          not close the sale within two hundred seventy (270) days after receipt
          of Tenant's notice or three hundred thirty (330) days after Landlord's
          Notice, as the case may be, then Landlord may not sell the Premises
          without again giving Tenant notice of its desire to sell said interest
          in the Premises as required by Section S.7(c).

          (f)  If Tenant does not purchase the Premises offered pursuant to this
     Section S.7 and the Premises is sold by Landlord in accordance with this
     Section S.7, then Tenant shall have no further right of first offer under
     this Section S.7 to purchase the Premises, but nothing herein shall affect
     Tenant's option to purchase the Premises pursuant to Section S.4 above.

          (g)  At such time as the rights of first offer of Tenant hereunder
     shall cease and be at an end and null and void, then at Landlord's request
     Tenant shall execute and deliver to Landlord an instrument in recordable
     form releasing all of its right under this Section S.7, which instrument
     may be filed of record.

          (h)  In the event request is made of Tenant for written confirmation
     that any proposed transaction is not subject to the rights of first offer
     granted to Tenant pursuant to the provisions of this Section S.7, then if
     Tenant has knowledge of said fact and if such is the case, Tenant, within
     ten (10) days after notice of the proposed transaction and requested
     confirmation, shall execute and deliver to the holder of any interest in
     the Premises requesting said confirmation, a written statement confirming
     that Tenant does not have the right of first offer with respect to said
     proposed transaction.

                                      -8-

          (i)  Except for the Closing Date and the Price and Terms described
     above, Tenant shall purchase the Premises on the terms and conditions set
     forth in the Purchase Contract. Within ten (10) days after Tenant accepts
     Landlord's Price and Terms or Landlord accepts Tenant's Price and Terms,
     Tenant shall deliver to Landlord four (4) copies of the Purchase Agreement
     modified to reflect the Price and Terms, the Closing Date and the property
     to be purchased. Within ten (10) days thereafter, Landlord shall execute
     such Purchase Contract and deliver two (2) execution copies to Tenant.

          (j)  If Landlord sells the Premises pursuant to Section S.7(e) above
     for a price (before deduction for the costs and expenses incurred in
     connection with such sale) ("Sales Price") in excess of the Applicable
     Option Price, then Landlord shall pay to Tenant an amount equal to fifty
     percent (50%) of the Excess Sale Proceeds (as defined below) at the same
     time and in the same manner as such Excess Sale Proceeds are paid to
     Landlord by the purchaser of the Premises. This Section S.7(j) shall not
     apply to any disposition of the Premises described in Section S.7(b). As
     used in this Section S.7(j):

               (i)    "Applicable Option Price" shall mean the Purchase Price
          determined pursuant to Section 3.1 of the Purchase Contract attached
          hereto as Rider E assuming (x) the Closing Date under such Contract
          was the date the Premises was sold by Landlord and (y) the Total
          Project Costs, as such term is used in the Purchase Contract, shall
          not include the sum of (aa) $7,236,000, (bb) the portion of the
          $500,000 Repair Allowance described in Section S.2 of the 1501 Lease
          which has been paid by Landlord and (cc) all other costs expended by
          Landlord to acquire the premises under the 1501 Lease from Tenant
          pursuant to the Purchase and Sale Agreement.

               (ii)   "Excess Sale Proceeds" shall mean the Sale Price less the
          Applicable Option Price and all costs and expenses incurred by
          Landlord to sell the Premises, including without limitation,
          prorations, attorney fees, title insurance and transfer taxes.

          (k)  As used herein "Landlord Affiliate" shall mean any natural person
     or any firm, corporation, partnership, limited liability company,
     association, trust or other entity which, directly or indirectly, controls,
     or is under common control with landlord (or if Landlord is an Illinois
     land trust, the holder of the beneficial interest in such land trust) and
     any firm, corporation, partnership, association, trust or other entity
     which is controlled by Landlord (or if Landlord is an Illinois land trust,
     the holder of the beneficial interest in such land trust). For purposes
     hereof, the term "control" shall mean the possession, directly or
     indirectly, of the power to direct or cause the direction of the management
     and policies of any entity or the power to veto major policy decisions of
     any entity, whether through the ownership of voting securities, by
     contract, or otherwise.

                                  ARTICLE 1.
                                GRANT AND TERM

     1.01  Grant of Lease.  Landlord, for and in consideration of the rents
reserved herein and of the covenants and agreements contained herein on the part
of Tenant to be performed, hereby leases to Tenant, and Tenant hereby leases
from Landlord, the Premises for the Term.

     1.02  Possession.  Tenant shall take possession of each Office Space Phase
on the Phase Commencement Date for such Phase. If Tenant takes possession of the
Building or any portion thereof for the conduct of its business prior to the
Phase Commencement Date for such space, all terms and provisions of this Lease
shall apply, including the obligation for the payment of Base Rent and Rent
Adjustments (both terms as hereinafter defined) for the portion of the Building
so occupied by Tenant at that time.

     Based upon Landlord's reasonable estimate of the progress of construction,
Landlord shall notify Tenant of the anticipated Commencement Date not less than
sixty (60) days prior thereto. Not less than five (5) days after the
Commencement Date, Landlord shall deliver to Tenant a factually correct
Commencement Notice in the form attached hereto as Exhibit B, setting forth the
Commencement Date, and the other matters set forth in said form, and Tenant
shall execute and return a copy of such notice to Landlord. The Commencement
Notice shall be conclusive and binding on Tenant as to all matters set forth
therein. Notwithstanding the foregoing, neither Landlord's failure to request
nor Tenant's failure to execute any Commencement Notice shall affect the
determination of the Commencement Date. If the Commencement Date occurs on other
than the first day of a calendar month, Tenant shall pay a proportionate Base
Rent in advance at the monthly rate set forth herein for such partial month, as
well as any Rent Adjustments for such partial month.

     1.03  Lease Year. As used in this Lease, the term "Lease Year" shall mean
(i) if the Commencement Date is the first day of a calendar month, the twelve
(12) month period commencing on the Commencement Date or (ii) if the
Commencement Date is not the first day of a calendar month, the period
commencing on the Commencement Date and ending on the last day of the twelfth
(12th) full calendar month of the Term, and in either case, each succeeding
twelve (12) month period thereafter which falls in whole or in part during the
Term.

                         CONSTRUCTION OF IMPROVEMENTS

     2.01  Construction of Improvements.  Subject to the terms and conditions
set forth in Sections 2.02 through 2.18, Landlord shall cause the Improvements,
as defined in Section 2.02, to be constructed on the Land.

                                     -10-
<PAGE>
 
     2.02  Landlord's Obligations. Landlord agrees to furnish all of the
material, labor and equipment for the construction of the improvements (the
"Base Building Improvements") specified in the "Outline Specifications for "Base
Building Improvements" attached hereto as Exhibit C and by this reference made a
part hereof. Landlord shall construct the Base Building Improvements in
accordance with the final plans and specifications for the Base Building
Improvements (the "Final Base Building Plans"), which Landlord shall cause to be
prepared in accordance with the "Schedule of Plan Submissions" attached hereto
as Exhibit D and by this reference made a part hereof. In addition, Landlord
agrees to furnish all of the material, labor and equipment for construction of
the Tenant office improvements (the "Office Improvements") in accordance with
final plans and specifications (the "Final Office Plans") which Tenant shall
cause to be prepared in accordance with the Schedule of Plan Submissions. The
term "Improvements" shall mean the Base Building Improvements and the Office
Improvements, collectively. The division of the Improvements between Base
Building Improvements and Office Improvements ("Tenant Improvement Work") is set
forth on attached Exhibit E.  The Improvements shall be constructed in a good
and workerlike manner and in accordance with Applicable Laws, as hereinafter
defined. The Final Base Building Plans and Final Office Plans (collectively, the
"Final Plans") shall be (a) subject to the approval of Landlord and any local
governmental agencies having jurisdiction over the construction of the
Improvements and (b) revised, and the Improvements shall be modified, to
incorporate any revisions thereto required by any governmental agency or
Landlord. Landlord shall submit a cost estimate for the Office Improvements to
Tenant together with a schedule for completing the Improvements which shall set
forth any Tenant Delays and costs attributable thereto that have become apparent
during the designing and pricing of the Improvements.

     2.03  Contractor and Architect. All work involved in the construction and
installation of the Improvements shall be carried out by a general contractor
selected by Landlord (the "Contractor"), under the sole direction of Landlord.
The Contractor shall be subject to Tenant's prior approval, such approval not to
be unreasonably withheld and such approval or disapproval shall be given to
Landlord within five (5) business days after requested by Landlord. Tenant
approves the Contractors listed on attached Exhibit F and by this reference made
a part hereof.

     Tenant shall engage an architect ("Tenant's Architect") licensed to
practice in the State of Illinois, to prepare the Final Office Plans. Tenant and
Tenant's Architect shall cooperate with Landlord, Contractor and Architect to
promote the efficient and expeditious completion of such work. Tenant's
Architect shall be subject to Landlord's reasonable approval.

     2.04  Landlord's Right to Make Changes. Landlord may (i) in preparing the
Final Base Building Plans, depart from the scope of the Outline Specifications
for Base Building Improvements due to reasons other than Changes, provided that
Tenant shall have the right to approve any Landlord Scope Changes materially
affecting the Building and (ii) make changes to the Final Plans provided the
Final Plans as modified, are consistent with the Base Building Improvements.
Landlord shall notify Tenant of any material changes to the Final Plans.
Tenant's consent shall be required for any changes having a value in excess of
$100,000. Tenant shall approve or disapprove such changes within three (3)
business days after Landlord's request for such consent.

                                     -11-
<PAGE>
 
     2.05  Definition of Changes. "Changes" shall mean any revisions to the
Improvements or the Final Plans which are (a) requested by Tenant and approved
by Landlord in Landlord's sole discretion, including, without limitation,
changes from the Outline Specifications for Base Building Improvements
(including any change in the square footage of the Building) which are
incorporated into the Final Plans during the initial preparation thereof, or (b)
required by any governmental agency in order to comply with any statutes,
ordinances, regulations or codes.

     2.06  Costs of Changes. If Landlord approves Changes requested by Tenant,
or if Changes are required by any governmental agency, Landlord shall reasonably
determine any changes in the Costs (as defined herein) of the Improvements and
deliver to Tenant a notice setting forth a pricing schedule (the "Pricing
Schedule") setting forth a schedule of the Costs of the Changes and its non-
binding estimate of any Tenant Delays resulting from such changes. Landlord
shall revise the Pricing Schedule from time to time to reflect any further
Changes since the prior Pricing Schedule. Tenant shall be deemed to have
approved all Costs of Changes in connection with Changes that are required by
any governmental agency in order to comply with any statutes, ordinances,
regulations or codes. In the case of Changes requested by Tenant, Tenant shall
approve or disapprove in writing the Costs of the Changes shown in the Pricing
Schedule or any revised Pricing Schedule within seven (7) days after Landlord
submits the revised Pricing Schedule to Tenant and, if such approval is not
received by Landlord within the applicable seven (7) day period, Tenant shall be
deemed to have disapproved the Costs of such Changes. If Landlord approves
Changes requested by Tenant and Tenant approves the revised Pricing Schedule in
writing, or if Changes are required by a governmental agency, the work to be
performed by Landlord shall include the revisions to the Improvements shown in
the revised Final Plans.

     2.07  Substitution of Materials.  Landlord, at its option, may substitute
for items or materials provided for in the Final Plans, as revised from time to
time, other items or materials of equal or better kind and quality if, in
Landlord's reasonable judgment, the use of the items or materials provided for
in the Final Plans would cause delay in the completion of construction;
provided, however, that any substitutions which will materially and adversely
affect Tenant's use and occupancy of the Premises for its intended purpose shall
only be made with Tenant's prior written consent, which consent shall not be
unreasonably withheld or delayed.

     2.08  Definition of Costs.  As used herein, the term "Costs" shall mean and
refer to all costs expended by Landlord relative to the construction of the
Improvements and acquisition of the Land, which shall include, without
limitation, the costs of equipment, material and labor, contractor's field
overhead and fees, architectural, design and engineering fees, fees and expenses
of architects and other professionals for presentations to governmental
agencies, construction management fees, space studies, working drawings,
governmental agency fees, permit expenses, interest on construction financing
from the date of disbursement until such financing shall be repaid in full at
the rate charged to Landlord by its construction lender, construction loan fees,
insurance premiums, title insurance premiums, testing and inspection costs,
sales and use taxes, permits, plan check fees, impact fees, bonds, zoning costs,
subdivision expenses, infrastructure improvements and donations, Taxes (as
hereinafter defined), closing costs, land acquisition costs, legal expenses,
costs to prepare "as built" plans and documentations for the Building and
materials necessary to properly maintain the Building, and other costs directly
or indirectly related to the construction of the Improvements.

                                     -12-
<PAGE>

     2.09  Payment of Costs. Landlord shall pay the Costs of the work provided
for in the Outline Specifications for Base Building Work and the amount of any
increases in the Costs of the work due to Landlord Scope Changes, and Changes
required by governmental authority which are not related to Tenant Delay or
Changes requested by Tenant or required as a result of Changes requested by
Tenant ("Base Building Governmental Changes"). Within ten (10) days after
receipt from Landlord from time to time of invoices therefor, Tenant shall pay
the amount of any net increases in the Costs of the work provided for in the
Outline Specifications for Base Building Improvements due to (i) Changes other
than Landlord Scope Changes and Base Building Governmental Changes or (ii)
Tenant Delay. Landlord shall contribute Six Million Dollars ($6,000,000) as
Landlord's share of the Costs of the Office Improvements. All Costs of the
Office Improvements in excess of Six Million Dollars ($6,000,000) (the "Excess
Costs") shall be paid by Tenant following Landlord's expenditure of Six Million
Dollars ($6,000,000) for Costs of Office Improvements as follows, subject to
adjustment when the actual Costs of the Office Improvements are finally
determined:

          (a)  The Costs of the Office Improvements in excess of Six Million
Dollars ($6,000,000) shall be paid by the Tenant within ten (10) days of
Tenant's receipt from Landlord of an invoice for such Excess Costs.

          (b)  If the Costs of the Office Improvements are less than Six Million
Dollars ($6,000,000) the difference shall be applied to pay the Costs due to (i)
Changes other than Landlord Scope Changes and Base Building Governmental Changes
and (ii) Tenant Delays, or to reimburse Tenant for such Costs previously paid by
Tenant. Tenant shall not be entitled to any rebate or credit from Landlord or
any abatement of Rent for any portion of such difference not applied to the
Costs of Changes or Tenant Delays because such difference is taken into account
in determining the Base Rent.

     2.10  Tenant's Right to Inspect the Building.  In the event Tenant
desires to inspect the Building prior to the time it is Ready for Occupancy,
Tenant shall so notify Landlord thereof in writing and Landlord shall attempt to
schedule the desired inspection with Contractor or Architect, provided that in
no event shall Tenant's inspection interrupt or interfere with any work then
being performed by Landlord or its contractors or agents at the time of such
inspection.

     2.11  Completion Date for the Building.  Construction of the Improvements
shall be pursued diligently so that portions of the Building shall be Ready For
Occupancy by the dates set forth on attached Exhibit G ("Required Completion
Dates"), subject to extension due to Tenant Delays and Force Majeure Delays. If
the applicable portions of the Building are not Ready for Occupancy on the
Required Completion Dates for reasons other than Tenant Delay or Force Majeure
Delays, then as Tenant's sole remedy for such delay, Tenant shall be entitled to
abate Base Rent, on a per diem basis, as follows: (i) for the first thirty (30)
days that the Ready for Occupancy date is so delayed, one and five tenths (1.5)
days for each day of such delay and (ii) for any period in excess of thirty (30)
days of delay, two (2) days for such day that the Ready for Occupancy date is
delayed. If Landlord believes that it will not be in a position to deliver the
Building Ready for Occupancy on or before the Required Completion

                                     -13-
<PAGE>
 
Date, Landlord shall be required to give Tenant thirty (30) days' advance notice
of the date upon which the Building shall be Ready for Occupancy.

     2.12  Definition of Ready for Occupancy.  Portions of the Building shall be
deemed "Ready for Occupancy" on the date of Substantial Completion (as defined
in Section 2.13) of the Improvements applicable to such portions of the
Building, or if the date of Substantial Completion is delayed due to Tenant
Delay (as hereinafter defined), the date Substantial Completion of the
Improvements applicable to such portions of the Building, would have occurred
but for such Tenant Delay.

     2.13  Punch List.  Not less than five (5) days prior to the Substantial
Completion of the Improvements, Landlord shall notify Tenant of a time and date
for inspection of the Improvements. Following Tenant's receipt of Landlord's
notice of a time and date for inspection of the Improvements, Tenant and
Tenant's Architect shall participate with Architect and Landlord in such
inspection, and Architect shall consult with Tenant's Architect regarding the
date of Substantial Completion and regarding the development by Architect of a
"Punch List" of items that are not yet completed; provided, however, that
Architect's determination of Substantial Completion and the Punch List shall be
conclusive. Tenant shall cause Tenant's Architect to cooperate with Architect in
developing the Punch List. Tenant agrees that, at the request of Landlord from
time to time, Tenant shall initial such Punch List or execute revised Punch
Lists to reflect partial completion of prior Punch List items. Landlord shall
diligently complete as soon as reasonably possible any items of work and
adjustment not completed on the date of Substantial Completion, and in
connection therewith, Landlord may enter into the Building to complete same.
Tenant may complete any Punch List items not completed within ninety (90) days
after date of Substantial Completion unless Landlord's failure to complete such
items was due to Landlord's or contractor's inability to obtain required
materials, Force Majeure Delays or Tenant Delays, Landlord shall reimburse
Tenant for the reasonable costs incurred by Tenant in completing the Punch List
items in accordance with this Section within thirty (30) days after receipt of
Tenant's invoice for such costs. Any costs incurred by Tenant to complete the
Punch List shall be included in the Costs of the Improvements. Such entry by
Landlord, its agents, employees, contractors or representatives for such purpose
shall not constitute an actual or constructive eviction, in whole or in part, or
entitle Tenant to any abatement or diminution of Base Rent or Rent Adjustments,
or relieve Tenant from any of its obligations hereunder, or impose any other
liability, on Landlord, its agents, employees, contractors or representatives.
As used herein, "Substantial Completion" means (i) for the Base Building Work,
the date certified by the architect as the date on which the Base Building
Improvements are substantially complete and (ii) for each Office Space Phase
described in Exhibit G, the date certified by the Architect as the date on which
the Improvements for such Office Space Phase are substantially complete so
Tenant can occupy the Office Space Phase for its normal business activity,
except for normal Punch List items not unreasonably interfering with Tenant's
use of the Office Space Phase and the mechanical, electrical, plumbing, heating,
ventilation and air conditioning systems serving the Office Space Phase are in
good working order.

     2.14  Contractor's and Landlord's Warranty.  In lieu of all other
warranties and liability by reason of the construction of the Improvements or
otherwise, Landlord and Contractor shall warrant, for a period of one (1) year
from the date that the Building is Ready for Occupancy, that the Building is
free from all defects in materials or workmanship, including latent defects.
Landlord shall assign said Contractor's warranty to Tenant upon completion of
the Improvements and deliver all operation and maintenance manuals to Tenant. At

constituted authorities relating thereto ("Applicable Laws"), including without
limitation all "Environmental Laws" (as such term is hereinafter defined), and
Landlord shall cause Architect to furnish a certificate to Tenant that the Base
Building Improvements have been designed in compliance and conformance with
applicable building codes (i) as a condition to obtaining Tenant's approval of
the Final Base Building Plans and (ii) promptly following substantial completion
of the Improvements. Tenant warrants and agrees that the Office Improvements
shall be designed in compliance with and conformance with all Applicable Laws
and Tenant shall cause Tenant's Architect to furnish a certificate to Landlord
that the Office Improvements have been designed in accordance with applicable
building codes (i) as a condition to obtaining Landlord's approval of the Final
Office Plans and (ii) promptly following substantial completion of the
Improvements. If it becomes necessary to obtain any governmental permit or
approval, other than the customary building permit, in order to construct the
Improvements, Tenant agrees to cooperate fully with Landlord in all respects in
order to obtain the same.

     2.16  Definition of Delays. As used in this Lease:

          (a)  "Tenant Delay" shall mean any delay in Landlord's completion of
the Improvements caused by:

          (i)    Tenant's or Tenant's Architect's failure to deliver or approve

Schedule, payable in equal monthly installments in the amount stipulated in the
Schedule, in advance on the first day of the Term and on the first day of each
calendar month thereafter of the Term, and at the same rate for fractions of a
month if the Term begins on any date except the first day of a calendar month or
ends on any day except the last day of a calendar month.

     3.02  Manner of Payment.  Base Rent, Tax Rent Adjustments (as hereinafter
defined), Tax Rent Adjustment Deposits (as hereinafter defined) and all other
amounts becoming due from Tenant to Landlord hereunder (hereinafter collectively
referred to as "Rent") shall be paid in lawful money of the United States to
Landlord at the office of Landlord, or as otherwise designated from time to time
by written notice from Landlord to Tenant. The payment of Rent hereunder is
independent of each and every other covenant and agreement contained in this
Lease, and Rent shall be paid without any setoff, abatement, counterclaim or
deduction whatsoever except as may be expressly provided herein.


                                  ARTICLE 4.
                                     TAXES

     4.01  Obligation to Pay Tax Rent Adjustments. In addition to paying Base
Rent specified in Section 3.01, Tenant shall also pay, as additional rent, the
amount of the Taxes due for each Adjustment Year (hereinafter referred to as
"Tax Rent Adjustments"). Tenant agrees and acknowledges that Landlord has made
no representation, warranty or guaranty relating to the amount of Taxes. Tenant
has not relied upon any statements or representations of Landlord or any agent
or affiliate of Landlord in regard to Taxes in executing this Lease and agreeing
to perform the terms and covenants hereof and shall make no claim against
Landlord based thereon.

     4.02  Definitions.  As used in this Lease,

          (a)  "Adjustment Year" shall mean the calendar year in which the first
Phase Commencement Date occurs and each subsequent calendar year, all or any
part of which falls within the Term.

          (b)  "Taxes" shall mean real estate taxes, general or special
assessments, sewer rents, rates and charges, transit and transit district taxes,
taxes based upon the receipt of rent, and any other federal, state or local
governmental charge, whether general, special, ordinary or extraordinary (but
not including income or franchise taxes or any other taxes imposed upon or
measured by Landlord's income or profits, except as provided herein), which may
now or hereafter be levied, assessed or imposed against the Real Property.

                                     -17-
<PAGE>
 
     Notwithstanding anything contained in this clause (b) to the contrary:

               (i)    If at any time the method of taxation then prevailing is
          altered so that any new or additional tax, assessment, levy,
          imposition or charge or any part thereof is imposed upon Landlord in
          place or partly in place of any such Taxes or contemplated increase
          therein, or in addition to Taxes, and is measured by or is based in
          whole or in part upon the Real Property or the rents or other income
          therefrom, then all such new taxes, assessments, levies, impositions
          or charges or part thereof, to the extent that they are so measured or
          based, shall be included in Taxes levied, assessed or imposed against
          the Real Property to the extent that such items would be payable if
          the Real Property were the only property of Landlord subject thereto
          and the income received by Landlord from the Real Property were the
          only income of Landlord.

               (ii)   Notwithstanding the year for which any such taxes or
          assessments are levied, (A) in the case of taxes or special
          assessments which may be paid in installments, the amount of each
          installment, plus any interest payable thereon, paid during a calendar
          year shall be included in Taxes for that year and (B) if any taxes or
          assessments payable during any calendar year shall be computed with
          respect to a period in excess of twelve (12) calendar months, then
          taxes or assessments applicable to the excess period shall be included
          in Taxes for that year. Except as provided in the preceding sentence,
          all references to Taxes "for" a particular year shall be deemed to
          refer to taxes levied, assessed or otherwise imposed for such year
          without regard to when such taxes are payable.

               (iii)  Taxes shall also include any personal property taxes
          (attributable to the calendar year in which paid) imposed upon the
          furniture, fixtures, machinery, equipment, apparatus, systems and
          appurtenances which are components of the Real Property.

          (c)  "Real Property" means the Building and Land.

     4.03  Payments of Tax Rent Adjustments. Tenant shall pay Tax Rent
Adjustments to Landlord as follows:

          (a)  Promptly after receipt of a statement from the appropriate
authority for any installment (including any estimated installment) of Taxes
payable during an Adjustment Year, Landlord shall furnish Tenant a written
notice ("Tax Installment Statement") setting forth the amount of Taxes shown to
be due on such statement of Taxes. Within fifteen (15) days after receipt of
Landlord's Tax Installment Statement, Tenant shall pay to Landlord the Tax
Adjustment shown as due on the Tax Installment Statement.

          (b)  Prior to the end of the final Adjustment Year, Landlord shall
deliver to Tenant a written notice ("Final Year Tax Notice") setting forth
Landlord's reasonable estimate, forecast or projection (the "Tax Projection") of
Taxes (1) applicable to any prior Adjustment Year which have not yet been paid
by Tenant to Landlord and (2) applicable to such final

                                     -18-
<PAGE>
 
Adjustment Year. Within fifteen (15) days following Landlord's delivery of the
Final Year Tax Notice, Tenant shall pay Landlord the Tax Projection shown on the
Final Year Tax Notice. Any Tax Projection paid by Tenant for any Adjustment Year
shall be applied as a credit against the amounts owed by Tenant for such
Adjustment Year pursuant to subparagraph (a) above, provided that if the Taxes
for such Adjustment Year are payable in installments, the Tax Projection applied
as a credit shall be divided equally among the installments to be paid by
Tenant.

          (c)  If any First Mortgagee (as defined in Section 18.01) requires
periodic deposits for Taxes or other security for the payment of Taxes, Tenant
shall pay such periodic deposits to Landlord when and as required by the First
Mortgagee or provide such security to the First Mortgagee. Any deposits made by
Tenant for an Adjustment Year shall be applied as a credit against Taxes payable
by Tenant pursuant to subparagraph (a) above and any Tax Projection required
under subparagraph (b) above. Landlord shall use reasonable efforts to exclude
from the First Mortgage documents any requirement for periodic deposits of Taxes
or other security for the payment of Taxes. If Landlord is unable to eliminate
the requirement for periodic deposits of Taxes, Landlord shall use reasonable
efforts to have such deposits held in an interest bearing account with the
interest to be held for Tenant's account.

     4.04  Proration and Survival.  With respect to any Adjustment Year which
does not fall entirely within the Term, Tenant shall be obligated to pay as Tax
Rent Adjustments for such Adjustment Year only a pro rata share of Tax Rent
Adjustments as herein determined, based upon the number of days of the Term
falling within the Adjustment Year. Following expiration or termination of this
Lease, Tenant shall pay any Tax Rent Adjustments due to Landlord within fifteen
(15) days after the date of each Landlord's Statement sent to Tenant. Without
limitation of other obligations of Tenant which shall survive the expiration of
the Term, the obligation of Tenant to pay Tax Rent Adjustments provided for in
this Article 4 accruing during the Term shall survive the expiration or
termination of this Lease.


                                  ARTICLE 5.
                                USE OF PREMISES

     Tenant shall use and occupy the Premises for general office purposes and
uses incidental thereto permitted under law and for no other use or purpose.


                                   ARTICLE 6.
                                   UTILITIES

     6.01  Payment for Utilities.  Tenant will pay, when due, all charges of
every nature, kind or description for utilities and other services furnished to
the Premises during the Term or chargeable against the Premises with respect to
the Term, including all charges for water, sewage, heat, gas, light, garbage,
electricity, telephone, steam, power, or other public or private utility
services. Tenant shall also pay for all utilities or services at the Premises
used by it or

                                     -19-
<PAGE>
 
its agents, employees or contractors prior to commencement of the Term.

     6.02  Utilities.  Tenant shall be responsible for contracting directly with
all suppliers of utility services. In the event that any charge or fee is
required by the State of Illinois, or by any agency, subdivision or
instrumentality thereof, or by any utility company or other entity furnishing
services or utilities to the Premises, as a condition precedent to furnishing or
continuing to furnish utilities or services to the Premises, such charge or fee
shall be deemed to be a utility charge payable by Tenant. The provisions of this
paragraph shall include, but shall not be limited to, any charges or fees for
present or future water or sewer capacity to serve the Premises, any charges for
the underground installation of gas or other utilities or services, and other
charges relating to the extension of or change in the facilities necessary to
provide the Premises with adequate utility services to the extent such
installations or extensions are not reflected in the Final Plans or any Changes
thereto. Tenant may elect to cause the Final Plans to provide for separate
metering of utilities to various portions of the Building. If Tenant makes such
an election, the Costs of such separate metering shall be paid in the same
manner as all other Costs of the Office Improvements by Tenant. In the event
that Landlord has paid any such charge or fee after the date hereof, Tenant
shall reimburse Landlord for such utility charge upon Landlord's demand
therefor. The inability of Tenant to obtain, or any stoppage of, the utility
services referred to in this Article 6 resulting from any cause shall not
constitute a constructive eviction, shall not make Landlord liable in any
respect for damages to any person, property or business, and shall not entitle
Tenant to any abatement of Rent or other relief from any of Tenant's obligations
under this Lease.


                                  ARTICLE 7.
                   CONDITION, CARE AND OPERATION OF PREMISES

     7.01  Condition of Premises.  Tenant's taking possession of the Premises or
any portion thereof shall be conclusive evidence against Tenant that the portion
of the Premises for which possession was taken in good order and satisfactory
condition, subject to Landlord's obligation to complete Punch List items and
latent defects in the Improvements.

     7.02  Tenant's Maintenance and Operation Obligations.  Tenant shall keep
the Premises, including any improvements thereto by Tenant, in good order and in
a safe, neat and clean condition and will take all action and will make, except
as otherwise stated herein, all structural and nonstructural, foreseen and
unforeseen and ordinary and extraordinary changes, repairs and replacements.
Tenant's obligations under this Article shall include without limitation all
repairs and replacements to the roof, structure, supports, foundation, floors,
gutters, downspouts, windows, doors, exterior walls, parking areas, and
sidewalks, the maintenance of the landscaping on the Premises in a neat and
attractive condition and the removal of all snow and ice from the walkways,
parking areas and drives on the Premises and the operation, maintenance and
repair of all building systems. It is the intent of the parties hereto, that
Tenant shall bear all responsibility for the maintenance, upkeep and replacement
of the Premises, Building and Land. Tenant's operation, maintenance and repair
of the Premises shall be conducted in accordance with the standards set forth on
Rider F attached hereto and made a part

                                     -20-
<PAGE>
 
hereof. In the event Tenant fails to commence promptly and pursue diligently the
performance of such maintenance or the making of such repairs or replacements,
then Landlord, at its option, may perform such maintenance or make such repairs
and replacements and Tenant shall reimburse Landlord, on demand after Tenant
receives an invoice therefor, the cost thereof plus a fee equal to fifteen
percent (15%) of the actual costs to cover the overhead. No representations
respecting the condition of the Premises or the Building have been made by
Landlord to Tenant except as specifically set forth in this Lease.
Notwithstanding the foregoing to the contrary, Tenant shall not have any
obligation to repair or replace any item covered by Landlord's and Contractor's
warranty described in Section 2.14. If Tenant incurs any costs in connection
with its maintenance and repair obligations with respect to the Base Building
Improvements during the last five (5) years of the Term or any Extended Term
(last seven (7) years in the case of a replacement of the roof of the Building)
which under generally accepted accounting principles ("GAAP") is required to be
capitalized and depreciated ("Base Building Capital Costs") and the Term of this
Lease expires prior to the end of the applicable depreciation period under GAAP,
then upon expiration of this Lease, Landlord shall pay to Tenant a pro rata
portion of such costs based on the ratio of the portion of the depreciation
period not included within the Term to the total depreciation period. Tenant
shall not incur any Base Building Capital Costs without Landlord's prior written
consent.

     7.03  Work Performed by Tenant.  All repairs made by Tenant pursuant to
Section 7.02 shall be performed in a good and workmanlike manner by contractors
or other repair personnel selected by Tenant and approved by Landlord. All
contracts for such maintenance and repair services shall be subject to
Landlord's reasonable approval. In no event shall such work be done for
Landlord's account or in a manner which allows any liens to be filed against the
Building or the Premises in violation of Article 27.

     7.04  Janitorial Service.  Tenant shall be responsible for providing
janitorial service for the Premises at Tenant's sole cost and expense in
accordance with the standards attached hereto as Rider C. Such janitorial
service shall be performed by a company and pursuant to a contract reasonably
satisfactory to Landlord.

     7.05  Waste.  Tenant shall not do or suffer any waste or damage,
disfigurement or injury to the Premises, or any improvements hereafter erected
thereon, or to the fixtures or equipment therein, or permit or suffer any
overloading of the floors or other use of the improvements that would place an
undue stress on the same or any portion thereof beyond that for which the same
was designed.


                                  ARTICLE 8.
                              RETURN OF PREMISES

     8.01  Surrender of Possession.  At the termination of this Lease by lapse
of time or otherwise, or upon termination of Tenant's right of possession
without termination of this Lease, Tenant shall surrender possession of the
Premises to Landlord and deliver all keys to the Premises to Landlord and make
known to Landlord the combination of all locks of vaults then

                                     -21-
<PAGE>
 
remaining in the Premises, and, subject to the following paragraph, shall return
the Premises and all equipment and fixtures of Landlord therein to Landlord in
as good condition as when Tenant originally took possession or, if there is a
Punch List, when the work provided for in the Punch List is completed, ordinary
wear, and damage resulting from the act of Landlord or its employees and agents
excepted, failing which Landlord may restore the Premises and such equipment and
fixtures to such condition and Tenant shall pay the cost thereof to Landlord on
demand.

     8.02  Installations and Additions.  All installations, additions,
partitions, hardware, light fixtures, non-trade fixtures and improvements,
whether temporary or permanent, except movable furniture and equipment belonging
to Tenant, in or upon the Premises, whether placed there by Tenant or Landlord,
shall be Landlord's property and shall remain upon the Premises, all without
compensation, allowance or credit to Tenant; provided, however, that if prior to
such termination or within ten (10) days thereafter Landlord so directs by
notice, Tenant, at Tenant's sole cost and expense, shall promptly remove such of
the installations, additions, partitions, hardware, light fixtures, non-trade
fixtures and improvements placed in the Premises by Tenant as are designated in
such notice and repair any damage to the Premises caused by such removal,
failing which Landlord may remove the same and repair the Premises and Tenant
shall pay the cost thereof to Landlord on demand.

     8.03  Trade Fixtures and Personal Property.  Tenant also shall remove
Tenant's furniture, machinery, safes, trade fixtures and other items of movable
personal property of every kind and description from the Premises and restore
any damage to the Premises caused thereby, such removal and restoration to be
performed prior to the end of the Term or within ten (10) days following
termination of this Lease or Tenant's right of possession, whichever is earlier.
If Tenant fails to remove such items, Landlord may do so and thereupon the
provisions of Section 17.06 shall apply and Tenant shall pay to Landlord upon
demand the cost of removal and of restoring the Premises.

     8.04  Survival.  All obligations of Tenant under this Article shall survive
the expiration of the Term or earlier termination of this Lease.


                                  ARTICLE 9. 
                                 HOLDING OVER

     Tenant shall pay Landlord for each day Tenant retains possession of the
Premises or any part thereof after termination of this Lease, by lapse of time
or otherwise, or of Tenant's right to possession of the Premises, an amount
which is double the amount of Base Rent and Rent Adjustments for a day based on
the annual rate of Base Rent set forth in Section 3.01 and on the Rent
Adjustments provided for in Article 4 in effect immediately prior to such
termination, and Tenant shall also pay all direct damages sustained by Landlord
by reason of such retention. Acceptance by Landlord of rent after such
termination, of itself, shall not constitute a renewal. Nothing contained in
this Section shall be construed or shall operate as a waiver of Landlord's right
of reentry or any other right or remedy of Landlord.

                             RULES AND REGULATIONS

     Tenant agrees to observe and not to interfere with the rights reserved to
Landlord contained in Article 11 and agrees, for itself, its employees, agents,
contractors, invitees and licensees, to comply with the rules and regulations
set forth in Rider B attached to this Lease and made a part hereof and such
other rules and regulations as may be adopted by Landlord pursuant to Section
11.01(e) of this Lease. Any violation by Tenant of any of the rules and
regulations contained in Rider B or any other Section of this Lease, or as may
hereafter be adopted by Landlord pursuant to Section 11.01(e) of this Lease, may
be restrained; but whether or not so restrained, Tenant acknowledges and agrees
that it shall be and shall remain liable for all damages, loss, costs and
expenses resulting from any violation by Tenant of any of said rules and
regulations.


                                  ARTICLE 11.
                          RIGHTS RESERVED TO LANDLORD

     11.01  Rights Reserved to Landlord.  Landlord reserves the following
rights, exercisable without notice and without liability to Tenant for damage or
injury to property, person or business and without effecting an eviction or
disturbance of Tenant's use or possession or giving rise to any claim for setoff
or abatement of Rent or affecting any of Tenant's obligations under this Lease:

          (a)  Except for portions of the Premises designated by Tenant as
"secured areas" on floor plans, delivered to Landlord, to retain at all times,
and to use in appropriate instances, pass keys to the Premises;

          (b)  Upon reasonable advance written or telephone notice, to exhibit
the Premises at reasonable hours, and to decorate, remodel, repair, alter or
otherwise prepare the Premises for reoccupancy at any time after Tenant vacates
or abandons the Premises;

          (c)  To enter the Premises at reasonable hours, upon reasonable prior
notice and for reasonable purposes, including inspection, subject to Tenant's
reasonable security restrictions;

          (d)  To make any repairs, alterations, improvements and additions in
and about the Building and the Premises during ordinary business hours and, if
Tenant desires to have such work done during other than business hours, Tenant
shall pay all overtime and additional expenses resulting therefrom; and

          (e)  From time to time to make and adopt such reasonable rules and
regulations, in addition to or other than or by way of amendment or modification
of the rules and regulations contained in Rider B or other Sections of this
Lease, which are not inconsistent

                                     -23-
<PAGE>
 
with the Terms of this Lease for the protection and welfare of the Building as
Landlord may determine, and Tenant agrees to abide by and comply with all such
rules and regulations.


                                  ARTICLE 12.
                                  ALTERATIONS

     Tenant shall not make, without the prior written consent of Landlord, any
alterations, additions or improvements to the Premises. Notwithstanding the
foregoing, Landlord's consent shall not be required for normal decorating work
such as painting and installation of wall coverings and carpeting. Landlord
shall not unreasonably withhold or delay its consent to alterations, additions
or improvements to the Building which do not affect the exterior, or structural
portions of the Building or the base building mechanical, electrical, plumbing,
elevator, security or other systems in the Building. If Landlord consents to
such alterations, additions or improvements, before commencement of the work or
delivery of any materials onto the Premises or into the Building, Tenant shall
furnish to Landlord, for its approval, plans and specifications, names and
addresses of contractors, copies of contracts, necessary permits and licenses,
and instruments of indemnification against any and all claims, costs, expenses,
damages and liabilities which may arise in connection with such work, all in
such form, substance and amount as may be satisfactory to Landlord. In addition,
prior to commencement of any such work or delivery of any materials into the
Premises, Tenant shall provide Landlord with appropriate evidence of Tenant's
ability to pay for such work and materials in full. All alterations, additions
and improvements shall be installed in a good, workerlike manner and only new,
high-grade materials shall be used. All such work shall be done only by
contractors or mechanics reasonably approved by Landlord and shall be subject to
Landlord's scheduling requirements and regulations. Tenant further agrees to
hold Landlord harmless from any and all liabilities of every kind and
description which may arise out of or be connected in any way with said
alterations, additions or improvements. Before commencing any work in connection
with such alterations, additions or improvements, Tenant shall furnish Landlord
with certificates of insurance from all contractors performing labor or
furnishing materials insuring Landlord against any and all liabilities which may
arise out of or may be connected in any way with said alterations, additions or
improvements. Tenant shall permit Landlord to supervise construction operations
in connection with the foregoing work if Landlord requests to do so. Tenant
shall pay the cost of all such alterations, additions and improvements, as well
as the cost of decorating the Premises occasioned by such alterations, additions
and improvements, including the cost of labor and materials, contractors'
profit, overhead, general conditions and a reasonable fee to Landlord. Upon
completing any alterations, additions or improvements, Tenant shall furnish
Landlord with (i) contractors' affidavits in form required by law, and full and
final waivers of lien and receipted bills covering all labor and materials
expended and used and (ii) "as built" or record drawings showing all
alterations, additions and improvements to the Premises. All alterations,
additions and improvements shall comply with all insurance requirements and with
all city and county ordinances and regulations and with the requirements of all
state and federal statutes and regulations.

                           ASSIGNMENT AND SUBLETTING

     13.01  Assignment and Subletting.  Without the prior written consent of
Landlord in each instance and subject to Sections 13.08 and 13.09 below, Tenant
shall not (a) assign, transfer, mortgage, pledge, hypothecate or encumber or
subject to or permit to exist upon or be subjected to any lien or charge, this
Lease or any interest under it; (b) allow to exist or to occur any transfer of
or lien upon this Lease or Tenant's interest herein by operation of law; (c)
sublet the Premises or any part thereof; or (d) permit the use or occupancy of
the Premises or any part thereof for any purpose not provided for under Article
5 of this Lease or by anyone other than Tenant and Tenant's employees. Landlord
has the absolute right to withhold its consent without giving any reason
whatsoever, except as expressly provided herein to the contrary. In no event
shall this Lease be assigned or assignable by voluntary or involuntary
bankruptcy proceedings or otherwise, and in no event shall this Lease or any
rights or privileges hereunder be an asset of Tenant under any bankruptcy,
insolvency or reorganization proceedings.

     13.02  Rentals Based on Net Income.  Without limiting the generality of the
foregoing provisions of this Article, Tenant expressly covenants and agrees not
to enter into any lease, sublease, license, concession or other agreement for
use, occupancy or utilization of the Premises which provides for rental or other
payment for such use, occupancy or utilization based in whole or in part on the
net income or profits derived by any person from the property leased, used,
occupied or utilized (other than an amount based on a fixed percentage or
percentages of receipts or sales), and that any such purported lease, sublease,
license, concession or other agreement shall be absolutely void and ineffective
as a conveyance of any right or interest in the possession, use, occupancy or
utilization of any part of the Premises.

     13.03  Tenant to Remain Obligated.  Consent by Landlord to any assignment,
subletting, use, occupancy or transfer shall not operate to relieve Tenant from
any covenant or obligation hereunder except to the extent, if any, expressly
provided for in such consent, or be deemed to be a consent to or relieve Tenant
from obtaining Landlord's consent to any subsequent assignment, transfer, lien,
charge, subletting, use or occupancy. Tenant shall pay all of Landlord's costs,
charges and expenses, including reasonable attorneys' fees, incurred in
connection with any assignment, transfer, lien, charge, subletting, use or
occupancy made or requested by Tenant. Tenant agrees that all advertising by
Tenant or on Tenant's behalf with respect to the assignment of this Lease or
subletting of space must be approved in writing by Landlord prior to publication
which approval shall not be unreasonably withheld or delayed.

     13.04  Landlord's Consent. Tenant shall advise Landlord, by written notice
("Tenant Notice"), of its intention from, on and after a stated date (which
shall not be less than sixty (60) days after the date of Tenant's notice) to
assign this Lease or to sublet any part or all of the Premises for any part of
the Term. Tenant's notice shall state the name and address of the proposed
subtenant or assignee, and a true and complete copy of the proposed sublease or
assignment and sufficient information to permit Landlord to determine the
financial responsibility and character of the proposed subtenant or assignee
shall be delivered to Landlord with said notice. Landlord will not withhold its
consent unreasonably to Tenant's assignment of this Lease

                                     -25-
<PAGE>
 
or Tenant's subletting the space covered by its notice. Landlord shall not be
deemed to have withheld its consent unreasonably to a sublease of part or all of
the Premises or an assignment of this Lease if its consent is withheld because:
(a) Tenant is then in Default hereunder; (b) any notice of termination of this
Lease or termination of Tenant's possession is given under Article 17; (c) the
portion of the Premises which Tenant proposes to sublease, including the means
of ingress thereto and egress therefrom and the proposed use thereof, and the
remaining portion of the Premises will violate any city, state or federal law,
ordinance or regulation, including, without limitation, any applicable building
code or zoning ordinances; (d) the proposed use of the Premises by the subtenant
or assignee does not conform with the use permitted by Article 5; (e) in the
reasonable judgment of Landlord, the proposed subtenant or assignee is of a
character or is engaged in a business which would be deleterious to the
reputation of the Building, or the subtenant or assignee is not sufficiently
financially responsible to perform its obligations under the proposed sublease
or assignment; (f) the sublessee's or assignee's business is likely to cause
greater wear and tear to the Premises than occasioned by Tenant's use or (g) the
proposed subtenant or assignee is a government or a government agency; provided,
however, that the foregoing are merely examples of reasons for which Landlord
may withhold its consent and shall not be deemed exclusive of any permitted
reasons for reasonably withholding consent, whether similar to or dissimilar
from to the foregoing examples. Landlord shall either approve or disapprove a
proposed assignment or sublease within thirty (30) days after receipt of the
information and documents described in the second sentence of this Section
13.04.

     13.05  Profits.  If Tenant, having first obtained Landlord's consent to any
sublease or assignment, or if Tenant or a trustee in bankruptcy for Tenant
pursuant to the Bankruptcy Code, assigns this Lease or sublets the Premises, or
any part thereof, at a rental or for other consideration in excess of the Rent
or pro rata portion thereof due and payable by Tenant under this Lease, then
Tenant shall pay to Landlord as additional rent fifty percent (50%) of any such
excess rent or other monetary consideration immediately upon receipt under any
such assignment or, in the case of a sublease, (a) on the first day of each
month during the term of any sublease the excess of all rent and other
consideration due from the subtenant for such month over the Rent then payable
to Landlord pursuant to the provisions of this Lease for said month (or if only
a portion of the Premises is being sublet, the excess of all rent and other
consideration due from the subtenant for such month over the portion of the Rent
then payable to Landlord pursuant to the provisions of this Lease for said month
which is allocable on a square footage basis to the space sublet) and (b)
immediately upon receipt thereof, any other consideration realized by Tenant
from such subletting; it being agreed, however, that Landlord shall not be
responsible for any deficiency if Tenant assigns this Lease or sublets the
Premises or any part thereof at a rental less than that provided for herein.
Notwithstanding the foregoing, Tenant shall not be required to pay Landlord any
amounts pursuant to this Section 13.05 until the amount of the excess rent and
other consideration received by Tenant equals the reasonable out of pocket costs
incurred by Tenant in entering into such sublease or assignment including
without limitation brokers' and attorneys' fees, advertising costs, tenant
buildout costs and construction allowances. The provisions of this Section 13.05
shall not apply to an assignment or sublease described in Sections 13.08 or
13.09 which does not require Landlord's consent.

assignee or guarantor certified by an independent public accounting firm.

          (c)  A Tenant Affiliate shall mean any person, corporation or other

                 WAIVER OF CERTAIN CLAIMS; INDEMNITY BY TENANT

     14.01  Waiver of Certain Claims; Indemnity by Tenant. To the extent not

part of it, or from any equipment or appurtenance therein, or from any accident

Landlord or to other tenants or occupants of the Building, results from any act

and liabilities, including reasonable attorneys' fees, for injuries to all
persons and damage to or theft or misappropriation or loss of property occurring

                       DAMAGE OR DESTRUCTION BY CASUALTY

     15.01  Tenant's Obligation to Rebuild.  In the event of damage to, or
destruction of, any improvements on the Premises, or of the fixtures and
equipment therein, by fire or other casualty, Tenant shall promptly, at its
expense, repair, restore or rebuild to the extent possible to the same design,
plans and specifications as existed prior to the casualty. Rent shall not be
reduced or abated during the period of such repair, restoration or rebuilding
even if the improvements are not tenantable.

     15.02  Preconditions to Rebuilding.  Before Tenant commences such
repairing, restoration or rebuilding involving an estimated cost of more than
Fifty Thousand Dollars ($50,000.00), plans and specifications therefor, prepared
by a licensed architect satisfactory to Landlord shall be submitted to Landlord
for approval and Tenant shall furnish to Landlord (a)

                                     -30-
<PAGE>
 
an estimate of the cost of the proposed work, certified to by said architect;
(b) satisfactory evidence of sufficient contractor's comprehensive general
liability insurance covering Landlord, builder's risk insurance, and workmen's
compensation insurance; and (c) such other security as Landlord may require to
insure payment for the completion of all work free and clear of liens.
Landlord's approval of the plans and specifications shall not be unreasonably
withheld if such plans and specifications comply with the provisions of Section
15.01.

     15.03  Payment for Rebuilding.  All sums arising by reason of loss under
the insurance referred to in Section 21.02(c) shall be deposited with the
Depository pursuant to Section 15.06, and Tenant shall deposit with the
Depository any excess cost of the work over the amount held by the Depository as
proceeds of the insurance within thirty (30) days from the date of the
determination of the cost of the work by the architect in accordance with
Section 15.02. Tenant shall diligently pursue the repair or rebuilding of the
improvements in a good and workmanlike manner, using only high quality workmen
and materials. The Depository shall pay out construction funds from time to time
on the written direction of the architect, after making provision for a
reasonable holdback, for the purpose of completing such repair or rebuilding and
upon receipt of appropriate contractors' statements, with supporting affidavits
and lien waivers. Notwithstanding the foregoing, if the cost of the repair or
restoration is less than $50,000, all proceeds of insurance shall be paid to
Tenant in trust to be used for restoration and repair of such damage.

     15.04  Excess Insurance Proceeds.  Any excess of money received from
insurance remaining with the Depository after the repair or rebuilding of
improvements, if there is no default by Tenant in the performance of the
Tenant's covenants and agreements hereunder, shall be paid to Tenant; otherwise
said moneys shall be paid to Landlord. If this Lease shall be terminated
pursuant to Section 15.05, all insurance proceeds shall be paid to by Landlord.

     15.05  Failure to Rebuild.  If (i) Tenant shall not enter upon the repair
or rebuilding of the improvements within a period of ninety (90) days after the
insurance proceeds are made available by Landlord pursuant to Section 15.03 or
(ii) after commencement of such repair or rebuilding, Tenant does not prosecute
the same thereafter with such dispatch as may be necessary to complete the same
within a reasonable period after said damage or destruction occurs, and the
repair and rebuilding is not completed within one year from the date the
insurance proceeds are made available pursuant to Section 15.03, then, in
addition to whatever other remedies Landlord may have either under this Lease,
at law or in equity, Landlord may retain insurance proceeds, or the balance
thereof remaining in the hands of Landlord as security for the continued
performance and observance by Tenant of the Tenant's covenants and agreements
hereunder, or Landlord may terminate this Lease or Tenant's possession of the
Premises and then retain the amount so held as damages resulting from the
failure on the part of Tenant to comply with the provisions of this Article.

     15.06  Deposits.  All insurance proceeds, condemnation awards and amounts
deposited by Tenant ("Net Proceeds") shall be deposited with a bank or other
financial institution designated by the First Mortgagee, or if there is no First
Mortgagee, by Tenant (the "Depository"). Tenant may direct the investment of the
amounts so deposited with the Depository in the following:

                                     -31-
<PAGE>
 
          (a)  repurchase obligations of the Depository at all times fully
secured by direct and general obligations of the United States of America or
obligations guaranteed as to principal and interest by the United States of
America;

          (b)  direct and general obligations of the United States of America or
obligations guaranteed as to principal and interest by the United States of
America purchased at a price not more than par;

          (c)  certificates of deposit of the Depository at all times secured as
provided by applicable law; or

          (d) commercial paper which is rated "A-1" or better (or comparable
ratings) by Standard & Poor's Corporation or "P-1" or better (or comparable
ratings) by Moody's Investors Service, Inc., or the successors to such rating
organizations.

     Such investments of such funds shall mature in such amounts and on such
dates as to provide that amounts shall be available on the draw dates sufficient
to pay the amounts requested, and due to, Landlord or Tenant as the case may be.
The Depository shall not be liable for any loss resulting from the liquidation
of each and every such investment. The terms and conditions relating to such
deposit and investments shall otherwise be satisfactory to Landlord, Tenant and
the Depository. All interest or other earnings net of investment fees of the
Depository shall be added to and deemed to be part of Net Proceeds.


                                  ARTICLE 16.
                                EMINENT DOMAIN

     16.01  Whole Taking.  If the entire Building or a substantial part thereof
is taken or condemned by any competent authority for any public or quasi-public
use or purpose, the Term of this Lease shall end upon and not before the earlier
of the date when the possession of the part so taken is required for such use or
purpose or the effective date of the taking, and without apportionment of the
award to or for the benefit of Tenant. If any condemnation proceeding is
instituted in which it is sought to take or damage any part of the Building, the
taking of which, in Landlord's opinion, would prevent the economical operation
of the Building, or if the grade of any street or alley adjacent to the Building
is changed by any competent authority, and such taking, damage or change of
grade makes it necessary or desirable to remodel the Building to conform to the
taking, damage or changed grade, Landlord shall have the right to terminate this
Lease upon not less than ninety (90) days' notice prior to the date of
termination designated in the notice. In either of these events, Rent at the
then current rate shall be apportioned as of the date of the termination. No
money or other consideration shall be payable by Landlord to Tenant for the
right of termination, and Tenant shall have no right to share in the
condemnation award, whether for a total or partial taking, for loss of Tenant's
leasehold or improvements or other loss or expenses or in any judgment for
damages caused by the change of grade. Tenant may however file a separate claim
for Allocation expenses and for any of Tenant's personal property taken,
provided such claim does not reduce Landlord's award.

                                     -32-
<PAGE>
 
     16.02  Partial Taking.  If only a part of the Premises shall be so taken or
condemned, and as a result thereof the balance of the Premises can be used for
the same purpose as prior to such taking, this Lease shall not terminate and
Tenant, at its sole cost and expense, shall repair and restore the Premises and
all improvements thereon to the extent of the condemnation award. Tenant shall
promptly and diligently proceed to make a complete architectural unit of the
remainder of the improvements first complying with the procedure set forth in
Section 15.02. The amount of the award relating to the improvements and shall be
held and disbursed in accordance with the procedure set forth in Sections 15.03
and 15.06. If Tenant does not make a complete architectural unit of the
remainder of the improvements within a reasonable period after such taking or
condemnation, not to exceed three hundred sixty five (365) days, then, in
addition to whatever other remedies Landlord may have either under this Lease,
at law or in equity, Landlord may receive the entire award or the balance
thereof remaining in the custody of the Depository, as the case may be, as
liquidated damages resulting from the failure of Tenant to comply with the
provisions of this Section. Any portion of such award as may not have to be
expended for such repairing or restoration shall be paid to Landlord. There
shall be no abatement or reduction in any rental because of such taking or
condemnation unless a portion of the Building is taken in which event Base Rent
shall abate based on the percentage of the rentable space in the Building so
taken and not replaced pursuant to this Section.


                                  ARTICLE 17.
                                    DEFAULT

thirty (30) days after notice thereof from Landlord to Tenant;

          (e)  The levy upon, under writ of execution or the attachment by legal
process of, the leasehold interest of Tenant, or the filing or creation of a
lien with respect to such leasehold interest, which lien shall not be released

                                     -33-

<PAGE>
 
            (f)  Tenant vacates or abandons the Premises or fails to take
possession of the Premises when available for occupancy (the transfer of a
substantial part of the operations, business and personnel of Tenant to some
other location being deemed, without limiting the meaning of the term, "vacates
or abandons," to be a vacation or abandonment within the meaning of this clause
(h) unless Tenant posts a full-time security guard at the Premises), whether or
not Tenant thereafter continues to pay Rent due under this Lease;

            (g)  Tenant becomes insolvent or bankrupt or admits in writing its

part of its property and is not discharged within sixty (60) days after such
appointment;

            (i)  Any bankruptcy, reorganization, arrangement, insolvency or
liquidation proceedings, or other proceedings for relief under any bankruptcy
law, or similar law for the relief of debtors, are instituted (i) by Tenant or
(ii) against Tenant and are allowed against it or are consented to by it or are
not dismissed within sixty (60) days after such institution;

            (j)  The aggregate number of days of Tenant Delay shall exceed
thirty (30); or

            (k)  A Default occurs under the 1501 Lease.

     17.02  Rights and Remedies of Landlord. If a Default occurs, Landlord shall
have the rights and remedies hereinafter set forth, which shall be distinct,
separate and cumulative and which shall not operate to exclude or deprive
Landlord of any other right or remedy allowed it by law:

            (a)  Landlord may terminate this Lease by giving to Tenant notice of
Landlord's election to do so, in which event the Term of this Lease shall end,
and all rights, title and interest of Tenant hereunder shall expire, on the date
stated in such notice;

            (b)  Landlord may terminate the right of Tenant to possession of the
Premises without terminating this Lease by giving notice to Tenant that Tenant's
right of possession shall end on the date stated in such notice, whereupon the
right of Tenant to possession of the Premises or any part thereof shall cease on
the date stated in such notice; and

            (c)  Landlord may enforce the provisions of this Lease and may

Tenant under any of the provisions of this Lease.

                                      -34-
<PAGE>
 
     17.03  Right to Re-Enter.  If Landlord exercises either of the remedies
provided for in Sections 17.02(a) or (b), Tenant shall surrender possession and
vacate the Premises and shall deliver immediately possession thereof to
Landlord, and Landlord may re-enter and take complete and peaceful possession of
the Premises, with process of law, full and complete license to do so being
hereby granted to Landlord, and Landlord may remove all occupants and property
therefrom, using such force as may be necessary, without being deemed guilty in
any manner of trespass, eviction or forcible entry and detainer and without
relinquishing Landlord's right to rent or any other right given to Landlord
hereunder or by operation of law.

     17.04  Current Damages.  If Landlord terminates the right of Tenant to
possession of the Premises without terminating this Lease, Landlord shall have
the right to immediate recovery of all amounts then due hereunder. Such
termination of possession shall not release Tenant, in whole or in part, from
Tenant's obligation to pay the Rent hereunder for the full Term, and Landlord
shall have the right, from time to time, to recover from Tenant, and Tenant
shall remain liable for, all Base Rent, Rent Adjustments and any other sums
accruing as they become due under this Lease during the period from the date of
such notice of termination of possession to the stated end of the Term. In any
such case, Landlord shall use diligent efforts to mitigate its damages and to
relet the Premises or any part thereof for the account of Tenant for such rent,
for such time (which may be for a term extending beyond the Term of this Lease)
and upon such terms as Landlord shall determine and collect the rents from such
reletting. Landlord shall not be required to accept any tenant offered by Tenant
or to observe any instructions given by Tenant relative to such reletting. Also,
in any such case, Landlord may make repairs, alterations and additions in or to
the Premises and redecorate the same to the extent reasonably deemed by Landlord
necessary or desirable and in connection therewith change the locks to the
Premises, and Tenant shall pay upon demand the cost of all the foregoing
together with Landlord's expenses of reletting. The rents from any such
reletting shall be applied first to the payment of the expenses of reentry,
redecoration, repair and alterations and the expenses of reletting and second to
the payment of Rent herein provided to be paid by Tenant. Any excess or residue
shall operate only as an offsetting credit against the amount of Rent due and
owing as the same thereafter becomes due and payable hereunder, and the use of
such offsetting credit to reduce the amount of Rent due Landlord, if any, shall
not be deemed to give Tenant any right, title or interest in or to such excess
or residue and any such excess or residue shall belong to Landlord solely, and
in no event shall Tenant be entitled to a credit on its indebtedness to Landlord
in excess of the aggregate sum, including Base Rent and Rent Adjustments, which
would have been paid by Tenant for the period for which the credit to Tenant is
being determined, had no Default occurred. No such reentry or repossession,
repairs, alterations and additions, or reletting shall be construed as an
eviction or ouster of Tenant or as an election on Landlord's part to terminate
this Lease, unless a written notice of such intention is given to Tenant, or
shall operate to release Tenant in whole or in part from any of Tenant's
obligations hereunder, and Landlord, at any time and from time to time, may sue
and recover judgment for any deficiencies from time to time remaining after the
application from time to time of the proceeds of any such reletting.

     17.05  Final Damages.  If this Lease is terminated by Landlord as provided
in Section 17.02(a), Landlord shall be entitled to recover from Tenant all Rent
accrued and unpaid for the period up to and including such termination date, as
well as all other additional sums payable


                                     -35-
<PAGE>
 
by Tenant, or for which Tenant is liable or in respect of which Tenant has
agreed to indemnify Landlord under any of the provisions of this Lease, which
may be then owing and unpaid, and all reasonable costs and expenses, including
court costs and attorneys' fees incurred by Landlord in the enforcement of its
rights and remedies hereunder, and, in addition, Landlord shall be entitled to
recover as damages for loss of the bargain and not as a penalty the aggregate
sum which at the time of such termination represents the excess, if any, of the
present value of the aggregate rents which would have been payable after the
termination date had this Lease not been terminated, including, without
limitation, Base Rent at the annual rate or respective annual rates for the
remainder of the Term provided for in Article 2 of this Lease or elsewhere
herein and the amount projected by Landlord to represent Rent Adjustments for
the remainder of the Term pursuant to Article 3 of this Lease, over the then
present value of the then aggregate fair rental value of the Premises for the
balance of the Term, such present worth to be computed in each case on the basis
of a five percent (5%) per annum discount from the respective dates upon which
such rentals would have been payable hereunder had this Lease not been
terminated, and (c) any damages in addition thereto, including reasonable
attorneys' fees and court costs, which Landlord has sustained as a result of the
breach of any of the covenants of this Lease other than for the payment of Rent.

     17.06  Removal of Personal Property.  All property of Tenant removed from
the Premises by Landlord pursuant to any provisions of this Lease or of law may
be handled, removed or stored by Landlord at the cost and expense of Tenant, and
Landlord in no event shall be responsible for the value, preservation or
safekeeping thereof. Tenant shall pay Landlord for all expenses incurred by
Landlord in such removal and storage charges against such property as long as
the same is in Landlord's possession or under Landlord's control. All such
property not removed from the Premises or retaken from storage by Tenant within
thirty (30) days after the end of the Term, however terminated, at Landlord's
option, shall be conclusively deemed to have been conveyed by Tenant to Landlord
as by bill of sale without further payment or credit by Landlord to Tenant.

     17.07  Attorneys' Fees.  Tenant shall pay all of Landlord's costs, charges
and expenses, including court costs and attorneys' fees, incurred in
successfully enforcing Tenant's obligations under this Lease, incurred by
Landlord in any action brought by Tenant in which Landlord is the prevailing
party, or incurred by Landlord in any litigation, negotiation or transaction in
which Tenant causes Landlord, without Landlord's fault, to become involved or
concerned. Landlord shall pay all of Tenant's costs, charges and expenses,
including court costs and attorneys' fees, incurred in successfully enforcing
Landlord's obligations under this Lease, incurred by Tenant in any action
brought by Landlord in which Tenant is the prevailing party, or incurred by
Tenant in any litigation, negotiation or transaction in which Landlord causes
Tenant without Tenant's fault, to become involved or concerned.

     17.08  Assumption or Rejection in Bankruptcy.  If Tenant is adjudged
bankrupt, or a trustee in bankruptcy is appointed for Tenant, Landlord and
Tenant, to the extent permitted by law, agree to request that the trustee in
bankruptcy determine within sixty (60) days thereafter whether to assume or to
reject this Lease.

                                 SUBORDINATION

     18.01  Subordination.  Landlord intends to execute and deliver and may
execute and deliver hereafter from time to time a first mortgage or first trust
deed in the nature of a mortgage, both being hereinafter referred to as a "First
Mortgage," against the Land and Building or any interest therein. If requested
by the mortgagee or trustee under any First Mortgagee, Tenant will either (a)
subordinate its interest in this Lease to said First Mortgage, and to any and
all advances made thereunder and to the interest thereon, and to all renewals,
replacements, supplements, amendments, modifications and extensions thereof, or
(b) make certain of Tenant's rights and interest in this Lease superior thereto;
and Tenant will execute and deliver such agreement or agreements promptly, as
may be reasonably required by such First Mortgagee; provided that, as a
condition to subordinating its rights and interests under this Lease to any
mortgage or trust deed, Tenant shall be entitled to require the First Mortgagee
to enter into a non-disturbance and attornment agreement with Tenant, which
agreement shall be in said holder's standard form not inconsistent with this
Lease. Tenant covenants it will not subordinate this Lease to any mortgage or
trust deed other than a First Mortgage without the prior written consent of the
First Mortgagee.

     18.02  Liability of Holder of First Mortgage; Attornment. It is further
agreed that (a) if any First Mortgage shall be foreclosed, (i) the holder of the
First Mortgagee, or purchaser at any foreclosure sale (or grantee in a deed in
lieu of foreclosure), as the case may be, shall not be (x) liable for any act or
omission of any prior landlord (including Landlord), (y) subject to any offsets
or counterclaims which Tenant may have against a prior landlord (including
Landlord), or (z) bound by any prepayment of Base Rent or Rent Adjustments which
Tenant may have made in excess of the amounts then due for the next succeeding
month, (ii) the liability of the First Mortgagee or purchaser at such
foreclosure sale or the liability of a subsequent owner designated as Landlord
under this Lease shall exist only so long as such trustee, mortgagee, purchaser
or owner is the owner of the Building or Land and such liability shall not
continue or survive after further transfer of ownership; and (iii) upon request
of the First Mortgagee, if the First Mortgage is foreclosed, Tenant will attorn,
as Tenant under this Lease, to the purchaser at any foreclosure sale under any
First Mortgage, and Tenant will execute such instruments as may be necessary or
appropriate to evidence such attornment; and (b) this Lease may not be modified
or amended so as to reduce Rent or shorten the Term provided hereunder, or so as
to affect adversely in any other respect to any material extent the rights of
Landlord, and this Lease shall not be cancelled or surrendered, without the
prior written consent, in each instance, of the First Mortgagee.

     18.03  Modification Required by First Mortgagee.  Should any prospective
First Mortgagee require a modification or modifications of this Lease, which
modification or modifications will not cause an increased cost or expense to
Tenant or in any other way materially change the rights and obligations of
Tenant hereunder, Tenant agrees that this Lease may be so modified and agrees to
execute whatever documents are required therefor and deliver the same to
Landlord within ten (10) days following the request therefor.

                                     -37-

     18.04  Short Form Lease.  Should any prospective First Mortgagee require
execution of a short form of lease for recording (containing the names of the
parties, a description of the Premises, and the term of this Lease) or a
certification from Tenant concerning this Lease in such form as may be required
by a prospective mortgagee, Tenant agrees to promptly execute such short form of
lease or certificate and deliver the same to Landlord within ten (10) days
following the request therefor.


                                  ARTICLE 19.
                             MORTGAGEE PROTECTION

     Tenant agrees to give any First Mortgagee, by registered or certified mail,
a copy of any notice or claim of default served upon Landlord by Tenant,
provided that prior to such notice, Tenant has been notified in writing, by way
of service on Tenant of a copy of an assignment of Landlord's interests in
leases, or otherwise, of the address of such First Mortgagee. Tenant further
agrees that if Landlord has failed to cure such default within twenty (20) days
after such notice to Landlord (or if such default cannot be cured or corrected
within that time, then such additional time as may be necessary if Landlord has
commenced within such twenty (20) days and is pursuing diligently the remedies
or steps necessary to cure or correct such default), then the First Mortgagee
shall have an additional thirty (30) days within which to cure or correct such
default (or if such default cannot be cured or corrected within that time, then
such additional time as may be necessary if such First Mortgagee has commenced
within such thirty (30) days and is pursuing diligently the remedies or steps
necessary to cure or correct such default, including the time necessary to
obtain possession if possession is necessary to cure or correct such default).

     Upon execution of this Lease by Landlord and Tenant, Tenant shall
simultaneously execute and deliver a copy of the Estoppel Certificate attached
hereto as Rider D. Tenant agrees that from time to time upon not less than ten
(10) days' prior request by Landlord, or any First Mortgagee or any ground
lessor, Tenant (or any permitted assignee, subtenant, licensee, concessionaire
or other occupant of the Premises claiming by, through or under Tenant) will
deliver to Landlord or to any First Mortgagee or ground lessor, a statement in
writing signed by Tenant certifying (a) that this Lease is unmodified and in
full force and effect (or if there have been modifications, that this Lease as
modified is in full force and effect and identifying the modifications); (b) the
date upon which Tenant began paying Rent and the dates to which Rent and other
charges have been paid; (c) that Landlord is not in default under any provision
of this Lease, or, if in default, the nature thereof in detail; (d) that the

or if not state the exceptions to the items not completed in accordance with the
Final Plans; (e) that there has been no prepayment of Rent other than that
provided for in this Lease; (f) that there are no actions, whether voluntary or

                                     -38-
<PAGE>
 
otherwise, pending against Tenant under the bankruptcy laws of the United States
or any State thereof; and (g) such other matters as may be reasonably required
and not inconsistent with the terms of this Lease by Landlord, the First
Mortgagee or ground lessor.


                                  ARTICLE 21.
                           SUBROGATION AND INSURANCE

     21.01  Waiver of Subrogation.  Landlord and Tenant agree to have all "all-
risk" coverage and other property damage insurance and any rent loss or business
interruption insurance which may be carried by either of them endorsed with a
clause providing that any release from liability of or waiver of claim for
recovery from the other party entered into in writing by the insured thereunder
prior to any loss or damage shall not affect the validity of said policy or the
right of the insured to recover thereunder and providing further that the
insurer waives all rights of subrogation which such insurer might have against
the other party. Without limiting any release or waiver of liability or recovery
set forth elsewhere in this Lease, and notwithstanding anything in this Lease
which may appear to be to the contrary, each of the parties hereto waives all
claims for recovery from the other party for any loss or damage to any of its
property insured under valid and collectible insurance policies to the extent of
any recovery collectible under such insurance policies. Notwithstanding the
foregoing or anything contained in this Lease to the contrary, any release or
any waiver of claims shall not be operative, and the foregoing endorsements
shall not be required, in any case where the effect of such release or waiver is
to invalidate insurance coverage or invalidate the right of the insured to
recover thereunder or increase the cost thereof (provided that in the case of
increased cost the other party shall have the right, within ten (10) days
following written notice, to pay such increased cost keeping such release or
waiver in full force and effect).

     21.02  Tenant's Insurance.  Tenant shall carry insurance during the entire
Term hereof with terms, coverages and in companies satisfactory to Landlord and
with such increases in limits as Landlord may request from time to time, but
initially Tenant shall maintain the following coverages in the following
amounts:

          (a)  Comprehensive or commercial general liability insurance,
     including contractual liability, on an occurrence basis, in an amount not
     less than Fifteen Million Dollars ($15,000,000.00) combined single limit
     per occurrence, covering Tenant, Landlord and its beneficiaries as a named
     insured and Landlord's mortgagee as an additional insured.

          (b)  Insurance against fire, sprinkler leakage, vandalism and the
     extended coverage perils for the full replacement cost of all additions,
     improvements and alterations to the Premises owned or made by Tenant, if
     any, and of all office furniture, trade fixtures, office equipment,
     merchandise and all other items of Tenant's property on the Premises, with
     loss or damage payable to Landlord and Tenant as their interests may
     appear.

                                     -39-
<PAGE>
 
          (c)  Standard Fire and Extended Coverage Policy and all other risks of
     direct physical loss as insured against under Special Extended Coverage
Endorsement, insuring the improvements at any time situated upon the Premises
against loss or damage by fire, lightning, wind storm, hail storm, aircraft,
vehicles, smoke, explosion, riot or civil commotion. The insurance coverage
shall be for not less than 100% of the full replacement cost of such improvement
with all proceeds of insurance payable to Landlord. Landlord shall be a named
insured on such policies. The insurance shall include standard mortgagee loss
payable clauses for benefit of Landlord's Mortgagee. The full replacement cost
of improvements shall be determined every five (5) years by an insurance
appraiser selected by Tenant with Landlord's reasonable approval and paid for by
Tenant or by other means reasonably acceptable to Landlord and its First
Mortgagee. Any insurance appraiser hired by Tenant shall submit a written report
of his appraisal to Landlord and Tenant and if said report shows that the
improvements are not insured as herein required, Tenant shall promptly obtain
such additional insurance as is required;

          (d)  Boiler Insurance, insuring Landlord and Tenant with the same
     limits of coverage as provided in subsection (c) for loss or damage by
     boiler or internal explosion or break down of boilers;

          (e)  Worker's Compensation Insurance, insuring Tenant from all
     worker's compensation claims;

          (f)  Plate Glass Insurance, insuring Landlord and Tenant from damage
     to any plate glass on the Premises; and

          (g)  Builders Risk Insurance insuring Landlord and Tenant against "all
     risks" including collapse and transit coverage during any construction of
     any improvements to or repair of the Premises after the Commencement Date
     covering the total value of work performed and equipment, supplies and
     material furnished.

          Such insurance shall be written by companies of nationally recognized
     financial standing, legally qualified to issue such insurance and accorded
     a rating by A.M. Best Company, Inc. of A:XII or higher at the time of
     issuance of any such policy. Each insurance policy carried by Tenant shall
     contain, where appropriate, a clause stating that such policy will be
     considered as primary insurance for Landlord and its agents and
     beneficiaries and not call into contribution any other insurance that may
     be available to Landlord. All insurance claims other than under Worker's
     Compensation and contents insurance pertaining to the Premises in amounts
     of $25,000 or less shall be adjusted by the insurer with Tenant, and all
     claims in excess of $25,000 shall be adjusted by Landlord and Tenant
     jointly.

     21.03  Certificates of Insurance.  Tenant shall furnish to Landlord, prior
to the commencement of the Term and at least thirty (30) days prior to the
expiration of such policies, policies or certificates evidencing such coverage,
which policies or certificates shall state that such insurance coverage may not
be reduced, cancelled or not renewed without at least thirty

                                     -40-
<PAGE>
 
(30) days' prior written notice to Landlord and Tenant (unless such cancellation
is due to nonpayment of premium, and in that case, only ten (10) days' prior
written notice shall be sufficient).

     21.04  Compliance with Requirements.  Tenant shall comply with all
applicable laws and ordinances, all orders and decrees of court and all
requirements of other governmental authorities, and shall not make any use of
the Premises, directly or indirectly, which may be prohibited thereby, which may
be dangerous to person or property, which may jeopardize any insurance coverage,
or which may increase the cost of insurance or require additional insurance
coverage.


                                  ARTICLE 22.
                                   NONWAIVER

     No waiver of any condition expressed in this Lease shall be implied by any
neglect of Landlord to enforce any remedy on account of the violation of such
condition whether or not such violation is continued or repeated subsequently,
and no express waiver shall affect any condition other than the one specified in
such waiver and that one only for the time and in the manner specifically
stated. Without limiting Landlord's rights under Article 9, it is agreed that no
receipt of moneys by Landlord from Tenant after the termination in any way of
the Term or of Tenant's right of possession hereunder or after the giving of any
notice shall reinstate, continue or extend the Term or affect any notice given
to Tenant prior to the receipt of such moneys. It is also agreed that after the
service of notice or the commencement of a suit or after final judgment for
possession of the Premises, Landlord may receive and collect any moneys due, and
the payment of said moneys shall not waive or affect said notice, suit or
judgment.


                                  ARTICLE 23.
                              TENANT'S AUTHORITY

     Tenant (a) represents and warrants that this Lease has been duly
authorized, executed and delivered by and on behalf of Tenant and constitutes
the valid and binding agreement of Tenant in accordance with the terms hereof,
(b) if Landlord so requests, it shall deliver to Landlord or its agent,
concurrently with the delivery of this Lease executed by Tenant, certified

a substitute therefor, Tenant's Authorized Representative set forth in the
Schedule shall have full power and authority to take action on behalf of and to
bind Tenant with respect to all matters relating to this Lease and the Premises.

other federal, state, or local agency or authority, or any other entity or
individual, concerning (i) any actual or alleged Release of a Hazardous Material
on, to or from the Premises; (ii) the imposition of any lien on the Premises;
(iii) any actual or alleged violation of, or responsibility under, any
Environmental Laws; or (iv) any actual or alleged liability under any theory of
common law tort or toxic tort, including without limitation, negligence,
trespass, nuisance, strict liability, or ultrahazardous activity.

     26.04  Landlord's Right to Inspect.  Landlord and Landlord's employees
shall have the right to enter the Premises and conduct appropriate inspections
or tests for the purpose of (i) determining Tenant's compliance with
Environmental Laws, and (ii) determining the type, kind and quantity of all
products, materials and substances brought onto the Premises, or made or
produced thereon. Landlord and its agents and representatives shall have the
right to take samples in quantities sufficient for analysis of all products,
materials and substances present on the Premises including, but not limited to,
samples, products, materials or substances brought onto or made or produced on
the Premises by Tenant or its agents, employees, contractors or invitees. Tenant
agrees to cooperate with such investigations by providing any relevant
information requested by Landlord, including, but not limited to, information
Landlord requests to comply with the Illinois Responsible Property Transfer Act,
Ill. Rev. Stat. ch. 30, para. 901 et seq. (1989), 765 ILCS 90/1 et seq. (1992).
Tenant may not perform any sampling, testing, or drilling to locate Hazardous
Materials in the Building components on the Premises without the Landlord's

premises. Tenant shall provide Landlord with the results of appropriate reports

with any permits issued under Environmental Laws, and with any other documents
necessary to demonstrate that Tenant complies with all Environmental Laws
relating to the Premises.

     26.06  Tenant's Obligation to Respond.  If Tenant's Management of Hazardous
Materials at the Premises (i) gives rise to liability or to a Claim under any
Environmental Law, or any common law theory of tort or otherwise; (ii) causes a
threat to, or endangers, the public health; or (iii) creates a nuisance or
trespass, Tenant shall, at its sole cost and expense, promptly take all
applicable action in response so as to comply with all applicable Environmental
Laws and eliminate or avoid any liability claim with respect thereto.

     26.07  Landlord's Right to Act.  In the event that Tenant shall fail to
comply with any of its obligations under this Article 26 as and when required
hereunder, Landlord shall have the right (but not the obligation) to take such
action as is required to be taken by Tenant hereunder and in such event, Tenant
shall be liable and responsible to Landlord for all costs, expenses,
liabilities, claims and other obligations paid, suffered, or incurred by
landlord in connection with such matters. Tenant shall reimburse Landlord

liabilities, damages, costs, and expenses, including, without limitation, loss
of rental income, loss due to business interruption, and reasonable attorneys'
fees and costs (collectively "Environmental Claims"), arising out of or in any
way connected with any or all of the following:

               (i)    any Hazardous Materials which, at any time during the
          Term, are or were actually or allegedly Managed, generated, stored,
          treated, released, disposed of or otherwise located on or at the
          Building or Land (regardless of the location at which such Hazardous
          Material are now or may in the future be located or disposed of),
          including but not limited to, any and all (1) liabilities under any
          common law theory of tort, nuisance, strict liability, ultrahazardous
          activity, negligence or otherwise based upon, resulting from or in
          connection with any Hazardous Material; (2) obligations to take
          Response, cleanup or corrective action pursuant to any investigation
          or remediation in connection with the decontamination, removal,
          transportation, incineration, or disposal of any of the foregoing; and

               (ii)   any actual or alleged illness, disability, injury, or
          death of any person; in any manner arising out of or allegedly arisen
          out of exposure to Hazardous Materials or other substances or
          conditions present at the Building or Land, regardless of when any
          such illness, disability, injury, or death shall have occurred or been
          incurred or manifested itself; and


                                     -45-
<PAGE>
 
               (iii)  any actual or alleged failure of Tenant or the Building
     or Land at any time and from time to time to comply with all applicable
     Environmental Laws, whether before or after the effective date of this
     Lease; and

               (iv) any failure by Tenant to comply with its obligations under
     this Article 26.

     In the event any Claims or other assertion of liability shall be made
against Landlord for which Landlord is entitled to indemnity hereunder, Landlord
shall notify Tenant of such Claim or assertion of liability and thereupon Tenant
shall, at its sole cost and expense, assume the defense of such Claim or
assertion of liability and continue such defense at all times thereafter until
completion. The obligations of Tenant under this Article 26 shall survive any
termination or expiration of this Lease. Nothing herein shall require Tenant to
indemnify, defend or hold harmless Landlord from, and Landlord shall reimburse,
defend, indemnify and hold Tenant, its employees, officers, directors,
shareholders and agents free and harmless from and against any Environmental
Claims arising out of or in anyway connected with any Hazardous Materials
Managed or Released on the Premises by Landlord or its agents, contractors or
employees.



                                  ARTICLE 27.
                       TITLE AND COVENANT AGAINST LIENS

     Landlord's title is and always shall be paramount to the title of Tenant
and nothing contained in this Lease shall empower Tenant to do any act which
can, shall or may encumber the title of Landlord. Tenant covenants and agrees
not to suffer or permit any lien of mechanics or materialmen to be placed upon
or against the Premises, the Building, the Land or against Tenant's leasehold
interest in the Premises and, in case of any such lien attaching, to pay and
remove same immediately. Tenant has no authority or power to cause or permit any
lien or encumbrance of any kind whatsoever, whether created by act of Tenant,
operation of law or otherwise, to attach to or to be placed upon the Premises,
the Building or the Land, and any and all liens and encumbrances created by
Tenant shall attach only to Tenant's interest in the Premises. If any such liens
so attach and Tenant fails to pay and remove or bond over the same within thirty
(30) days, Landlord, at its election, may pay and satisfy the same and in such
event the sums so paid by Landlord, with interest from the date of payment at
the rate set forth in Section 28.08 for amounts owed Landlord by Tenant. Such
sums shall be deemed to be additional rent due and payable by Tenant at once
without notice or demand.


                                  ARTICLE 28.
                                 MISCELLANEOUS

     28.01  Successors and Assigns.  Each provision of this Lease shall extend
to and shall bind and inure to the benefit not only of Landlord and Tenant, but
also of their respective heirs, legal representatives, successors and assigns,
but this provision shall not operate to permit any transfer, assignment,
mortgage, encumbrance, lien, charge or subletting contrary to the provisions of
this Lease.

this Lease or of any of its conditions or provisions shall be binding upon
Landlord unless in writing and signed by Landlord.

     28.03  No Option; Irrevocable Offer.  Submission of this instrument for
examination shall not constitute a reservation of or option for the Premises or
in any manner bind Landlord and no lease or obligation on Landlord shall arise
until this instrument is signed and delivered by Landlord and Tenant; provided,
however, the execution and delivery by Tenant of this Lease to Landlord or the
agent of Landlord's beneficiary, if any, shall constitute an irrevocable offer
by Tenant to lease the Premises on the terms and conditions contained herein,
which offer may not be revoked for thirty (30) days after such delivery.

     28.04  Financial Statements.  Tenant shall furnish Landlord annually within
ninety (90) days after the end of Tenant's fiscal year with a copy of its annual
audited and certified statement, prepared in accordance with generally accepted
accounting principles and certified by a reasonable financial officer of Tenant.
Tenant agrees that Landlord may deliver a copy of such statements to its
mortgagee or ground lessor, but otherwise Landlord shall treat such statements
and information contained therein, to the extent not otherwise available to the
public, as confidential.

     28.05  Definition of Landlord.  The term "Landlord" as used in this Lease
means only the owner or owners at the time being of the Building so that in the
event of any assignment, conveyance or sale, once or successively, of said
Building, or any assignment of this Lease by Landlord, said Landlord making such
sale, conveyance or assignment shall be and hereby is entirely freed and
relieved of all covenants and obligations of Landlord hereunder accruing after
such sale, conveyance or assignment, and Tenant agrees to look solely to such
purchaser, grantee or assignee with respect thereto who shall be deemed to have
assumed such covenants and obligations occurring after such sale, conveyance or
assignment. This Lease shall not be affected by any such assignment, conveyance
or sale, and Tenant agrees to attorn to the purchaser, grantee or assignee.

     28.06  Headings.  The headings of Articles and Sections are for convenience
only and do not limit, expand or construe the contents of the Articles or
Sections.

     28.07  Time of Essence.  Time is of the essence of this Lease and of all
provisions hereof.

     28.08  Default Rate of Interest.  All amounts, including, without
limitation, Base Rent and Rent Adjustments, owed by Tenant to Landlord pursuant
to any provision of this Lease shall bear interest from the date due until paid
at the annual rate of five percent (5%) in excess of the rate of interest
announced from time to time by The First National Bank of Chicago, as its prime,
reference or corporate base rate, changing as and when said prime, reference or
corporate base rate changes, unless a lesser rate shall then be the maximum rate
permissible by law with respect thereto, in which event said lesser rate shall
be charged.

     28.09  Severability.  The invalidity of any provision of this Lease shall
not impair or affect in any manner the validity, enforceability or effect of the
rest of this Lease.

     If the annual Base Rent for any period described above cannot be determined
as of the first day of such period, then until such amount is determined, Tenant
shall pay Base Rent at the minimum rate set forth for such period (or, in the
case of the Base Rent as of Commencement Date, assuming the Fixed Rental Rate

notify Tenant in writing of such amount within thirty (30) days thereafter and
Tenant, in the case of an underpayment, shall pay to Landlord any additional
Base Rent due for the portion of such period prior to the date of such payment,

     If Tenant exercises its option to extend the Term for an Extended Term,
then within thirty (30) days after receipt of Tenant's notice exercising the
Extension Option (or, if later, eight (8) months prior to the end of the then

the Extended Term in question. If the Market Rent determined by Landlord is
greater than the Base Rent determined pursuant to clause (2) of paragraphs

after receipt of Landlord's notice of the Market Rent, Tenant shall elect in a
written notice ("Tenant's Rent Determination Notice"), delivered to Landlord
either (i) to accept Landlord's determination of the Market Rent or (ii) to have
the Market Rent determined by appraisal pursuant to paragraph (c) below, in
which event Tenant shall also set forth its determination of the Market Rent. If
Tenant fails to timely deliver such notice, Tenant will be deemed to have
accepted Landlord's determination of the Market Rent.

(b)  As used in this Rider A and in the Lease:

     (i)    "Adjusted Rental Costs" shall mean:

            (A)  An amount equal to the product of (1) the Maximum Project Cost,
                 (2) the annual constant necessary to amortize the Maximum Total
                 Project Cost with interest at the Amortization Rate over 
                 twenty-five (25) years, and (3) 1.1; reduced by

            (B)  $1,500,262.40, which amount is the annual Base Rent payable
                 under the 1501 Lease.

     (ii)   "Amortization Rate" shall mean 200 basis points over the annual
            yield on ten (10) year United States Treasury Bills issued on a date
            prior to the Commencement Date selected by Landlord. Within thirty
            (30) days after selection of such date Landlord shall advise Tenant
            in writing of the date to be used to determine the Amortization Rate
            and such rate.

     (iii)  "CPI" shall mean the Revised Consumer Price Index for Urban Wage
            Earners and Clerical Workers, All Items (base index year 1982-
            84=100), for Chicago, Gary, Lake County, IL-IN-WI, as published by
            the United States Department of Labor, Bureau of Labor Statistics.
            If the manner in which the Consumer Price Index is determined by the
            Bureau of Labor Statistics shall be substantially revised,
            including, without limitation, a change in the base index year, a
            reasonable adjustment shall be made by Landlord in such revised
            index which would produce results equivalent, as nearly as possible,
            to those which would have been obtained if such Consumer Price Index
            had not been so revised. If the Consumer Price Index shall become
            unavailable to the public because publication is discontinued, or
            otherwise, or if equivalent data is not readily available to enable
            Landlord to make the adjustment referred to in the preceding
            sentence, then Landlord will substitute therefor a comparable index
            based upon changes in the cost of living or purchasing power of the

            submitted by Tenant is the Market Rent for the Premises for the
            Extended Term in question.

     Premises are situated and have an MAI certification or be licensed leasing
     brokers based in Metropolitan Chicago, shall not have a financial interest
     in Landlord or Tenant and shall otherwise be impartial.

     If Tenant fails to appoint its appraiser in the manner and within the time
     specified in (i) above, then the Market Rent shall be the Market Rent
     determined by Landlord. If Landlord fails to appoint its appraiser in the
     manner and within the time prescribed in clause (ii), then such Market Rent
     shall be the Market Rent set forth in the Tenant's Rent Determination
     Notice.

     If the appraisers selected by Tenant and Landlord fail to appoint the third
     appraiser within the time and in the manner prescribed in clause (iii)
     above, then Landlord and Tenant shall jointly and promptly apply to the
     local office of the American Arbitration Association for the appointment of
     the third appraiser.

     The decision of the appraisers shall be binding, final and conclusive on
     the parties (unless it shall be manifest that the appraiser or one or more
     of the appraisers shall not be an impartial person) and shall be
     enforceable by either party in a court of competent jurisdiction. The cost
     of the foregoing appraisal process (including any court costs) shall be
     borne equally by the parties).

                         FIRST AMENDMENT TO 3333 LEASE
                         -----------------------------

     THIS AMENDMENT, made as of the 1st day of November, 1997, between BANK ONE,
ILLINOIS, N.A., not personally but solely as Trustee under Trust Agreement dated
May 23, 1997, and known as Trust No. 11097 ("Landlord") and MAY & SPEH, INC.
("Tenant").

                                   RECITALS

     Landlord and Tenant are parties to a written lease dated June 2, 1997,
("3333 Lease"), for the entire building ("3333 Building") to be constructed at
3333 Finley Road, Downers Grove, Illinois. Section S.4 of the 3333 Lease grants
Tenant certain options to acquire the 3333 Building and the land thereunder;
provided that, Tenant also exercises the option to purchase the building ("1501
Building") commonly referred to as 1501 Opus Place, Downers Grove, Illinois and
the land thereunder pursuant to the option granted in the lease between Landlord
and Tenant also dated June 2, 1997 for the 1501 Building ("1501 Lease").

     The terms and conditions of Tenant's option to purchase the 1501 Building
are set forth in Rider E to the 1501 Lease and the terms and conditions of the
purchase of the 3333 Building are set forth in Rider E to the 3333 Lease. The
purchase price for the 1501 Building is set forth in Rider E to the 1501 Lease
and the purchase price for the 3333 Building is based on a formula which takes
into account the purchase price for the 1501 Building. Landlord and Tenant
desire to increase the purchase price for the 1501 Building and to make a
similar reduction to the purchase price of the 3333 Building to permit Landlord
to refinance the 1501 Building and to finance the construction of the 3333
Building.

     Landlord and Tenant also desire to modify the Base Building Improvements
under the 3333 Lease to include the construction of a tunnel ("Tunnel") from the
3333 Building to the 3333 Building and to modify the Maximum Project Costs to
take into account the change in the Base Building Improvements. In addition
Landlord and Tenant have agreed on the interest rate to be used to determine the
Base Rent and wish to set forth such amount in this amendment.

     Finally, Landlord exchanged a portion of the Land as described in the Lease
located along Finley Road for a like parcel owned by the Village of Downers
Grove and Landlord and Tenant desire to amend the Lease to reflect the change in
the Land.

     NOW, THEREFORE, in consideration of the mutual covenants and conditions
contained herein, the Lease is hereby amended as follows:

     1. All capitalized terms used herein shall have the same meanings as in the
3333 Lease unless otherwise defined herein.

     2. Exhibit A to the 3333 Lease shall be replaced by Exhibit A to this
Amendment.

     3. Notwithstanding anything in the 3333 Lease to the contrary, the Base
Building Improvements shall include the work described on attached Exhibit B.
<PAGE>
 
     4. Notwithstanding anything in the 3333 Lease to the contrary, the Premises
shall include the portion of the Tunnel located on the Land and Tenant's
obligations under this Lease with respect to the Premises, including without
limitation, its obligations to maintain and repair the Premises shall apply to
the portion of the Tunnel included in the Premises.

     5. Rider A to the 3333 Lease shall be replaced with Rider A to this
Amendment.

     6. Section 3.1 of the Purchase Contract attached as Rider E to the 3333
Lease is amended in its entirety to read as follows:

          3.1 PURCHASE PRICE. The purchase price ("Purchase Price") for the
     Property shall be __________________ ___________________
     ($__________________________).

     [The purchase price shall be the product of (i), (ii) and (iii) below, less
     Twelve Million Eight Hundred Thousand Dollars ($12,800,000.00) :

               (i) The Total Project Costs as defined in Rider A to the 3333
     Lease;

               (ii) 1.125 and

               (iii) The lesser of (A) 1.04/N/ (where "N" is the number of years
     from January 1, 1997 to the Closing Date) and (B) one plus the percentage
     increase, if any, in the CPI (as defined in Rider A of the 3333 Lease) from
     January 1, 1997 to the Closing Date.

          Purchaser agrees to pay to Seller and Seller agrees to accept payment
     of the Purchase Price as follows:

               (a) At Closing, Purchaser shall accept title to the Property
     subject to the lien of the First Mortgage (which Purchaser or its nominee
     or designee will take subject to, and with respect to which First Mortgage
     and the loan evidenced and secured thereby Purchaser or its nominee or
     designee shall assume), and the outstanding principal balance thereunder
     shall be credited against the Purchase Price.

               (b) The remaining portion of the Purchase Price, subject to
     prorations and adjustments as provided in Section 8.1, shall be paid on the
     Closing Date by wire transfer of immediately available funds, first to the
     Title Company and then to an account specified by Seller, against delivery
     of instruments of transfer and the other documents specified in Section
     7.1.

and conditions of the Lease and all the rights and obligations of Landlord and
Tenant thereunder, shall remain in full force and effect, and are not otherwise
altered, amended, revised or changed.

whatsoever, and in case of default hereunder by Landlord (or default through,
under or by any of its beneficiaries, or agents or representatives of said

against, said Landlord, individually or personally, but only as trustee under
the provisions of the trust agreement establishing the trust, or against any of
the beneficiaries under the trust agreement establishing the trust on account of
this Lease or on account of any representation, warranty, covenant, undertaking
or agreement of Landlord contained in this Lease, either express or implied, all

       If the annual Base Rent for any period described above cannot be
determined as of the first day of such period, then until such amount is
determined, Tenant shall pay Base Rent at the minimum rate set forth for such
period (or, in the case of the Base Rent as of Commencement Date, assuming the
Fixed Rental Rate was $16.51). When the actual annual Base Rent is determined,
Landlord shall notify Tenant in writing of such amount within thirty (30) days
thereafter and Tenant, in the case of an underpayment, shall pay to Landlord any
additional Base Rent due for the portion of such period prior to the date of
such payment, or Landlord, in the case of an overpayment, shall pay to Tenant

       If Tenant exercises its option to extend the Term for an Extended Term,
then within thirty (30) days after receipt of Tenant's notice exercising the
Extension Option (or, if later, eight (8) months prior to the end of the then
Term), Landlord shall notify Tenant of its determination of the Market Rent for
the Extended Term in question. If the Market Rent determined by Landlord is
greater than the Base Rent determined pursuant to clause (2) of paragraphs
(a)(v), (vi) or (vii) above, as the case may be, then within thirty (30) days
after receipt of Landlord's notice of the Market Rent, Tenant shall elect in a
written notice ("Tenant's Rent Determination Notice"), delivered to Landlord
either (i) to accept Landlord's determination of the Market Rent or (ii) to have
the Market Rent determined by appraisal pursuant to paragraph (c) below, in
which event Tenant shall also set forth its determination of the Market Rent. If
Tenant fails to timely deliver such notice, Tenant will be deemed to have
accepted Landlord's determination of the Market Rent.

(b)    As used in this Rider A and in the Lease:

       (i)    "CPI" shall mean the Revised Consumer Price Index for Urban Wage
              Earners and Clerical Workers, All Items (base index year 
              1982-84=100), for Chicago, Gary, Lake County, IL-IN-WI, as
              published by the United States Department of Labor, Bureau of
              Labor Statistics. If the manner in which the Consumer Price Index
              is determined by the Bureau of Labor Statistics shall be
              substantially revised, including, without limitation, a change in
              the base index year, a reasonable adjustment shall be made by
              Landlord in such revised index which would produce results
              equivalent, as nearly as possible, to those which would have been
              obtained if such Consumer Price Index had not been so revised. If
              the Consumer Price Index shall become unavailable to the public
              because publication is discontinued, or otherwise, or if
              equivalent data is not readily available to enable Landlord to
              make the adjustment referred to in the preceding sentence, then
              Landlord will substitute therefor a comparable index based upon
              changes in the cost of living or purchasing power of the consumer
              dollar published by any other governmental agency or, if no such
              index is available, then a comparable index published by a
              university, a major bank or other financial institution, or a
              comparable and recognized financial publication.

       (ii)   "Fixed Rental Rate" shall mean $16.51 per rentable square foot;
              provided that such amount shall be reduced $0.055 for every
              $100,000 (and prorated for amounts less than $100,000) that the
              Maximum Project Cost is less than $43,686,805; provided that there
              shall be no reduction in the Fixed Rental Rate if the Costs of
              Office Improvements, Costs due to changes (other than Landlord
              Scope Changes) and Tenant Delays exceeds $5,500,000 but is less

              Office Improvements, Costs due to Changes (other than Landlord
              Scope Changes) and Tenant Delays, not in excess of $6,000,000.

       (iv)   "Market Rent" shall mean the then prevailing market rental rate
              per rentable square foot of area for space comparable to the space
              to be leased by Tenant pursuant for the term of the lease of such
              space, taking into account applicable loss factors, applicable
              lengths of lease term, the creditworthiness of the tenants,
              differences in the size of the space leased, the then market
              rental conditions, the condition of the subject premises and
              comparable space, the location of amenities in the Building and
              comparable buildings, the fact that this Lease is a triple net

              such appraiser's name, address and telephone number ("Tenant's

                                      -4-
<PAGE>
 

       (ii)   Within twenty (20) days after receipt of Tenant's Selection
              Notice, Landlord shall select and retain an appraiser of its
              choice and give Tenant written notice of such appraiser's name,
              address and telephone number "(Landlord's Selection Notice").

       (iii)  The appraisers so selected by Tenant and Landlord shall then
              select an individual as a third appraiser within five (5) days
              after receipt by Tenant of Landlord's Selection Notice and furnish
              Landlord and Tenant written notice of such appraiser's name,
              address and telephone number and Landlord and Tenant shall retain
              the services of such third appraiser.

       (iv)   Within fifteen (15) days following selection of the appraisers,
              Landlord and Tenant shall each simultaneously submit to the other
              their respective determinations of the Market Rent. During the
              next seven (7) days both Landlord and Tenant shall prepare a
              written critique of the other's determination and on the seventh
              (7th) day Landlord's and Tenant's determinations (as previously
              submitted to the other party with no modifications or additions
              whatsoever) and Landlord's and Tenant's critiques shall be
              submitted to the appraisers.

       (v)    The three (3) appraisers shall then determine by majority vote
              whether the Market Rent submitted by Landlord or the Market Rent
              submitted by Tenant is the Market Rent for the Premises for the
              Extended Term in question.

       All appraisers selected pursuant to this paragraph shall have at least
       ten (10) years experience with commercial property in the area where the
       Premises are situated and have an MAI certification or be licensed
       leasing brokers based in Metropolitan Chicago, shall not have a financial
       interest in Landlord or Tenant and shall otherwise be impartial.

       If Tenant fails to appoint its appraiser in the manner and within the
       time specified in (i) above, then the Market Rent shall be the Market
       Rent determined by Landlord. If Landlord fails to appoint its appraiser
       in the manner and within the time prescribed in clause (ii), then such
       Market Rent shall be the Market Rent set forth in the Tenant's Rent
       Determination Notice.

       If the appraisers selected by Tenant and Landlord fail to appoint the
       third appraiser within the time and in the manner prescribed in clause
       (iii) above, then Landlord and Tenant shall jointly and promptly apply to
       the local office of the American Arbitration Association for the
       appointment of the third appraiser.

       The decision of the appraisers shall be binding, final and conclusive on
       the parties (unless it shall be manifest that the appraiser or one or
       more of the appraisers shall not be an impartial person) and shall be
       enforceable by either party in a court of competent jurisdiction. The
       cost of the foregoing appraisal process (including any court costs) shall
       be borne equally by the parties).
