                               PROSPECTUS SUMMARY
 
     The following summary is qualified in its entirety by, and should be read
in conjunction with, the more detailed information and the financial statements
and related notes thereto appearing elsewhere in this Prospectus. SPR Inc.
("SPR" or the "Company") is a Delaware corporation recently organized in
connection with the mergers into it of SPR Chicago Inc., an Illinois corporation
("SPR Chicago"), Systems & Programming Resources of Tulsa, Inc., an Oklahoma
corporation ("SPR Tulsa"), SPR-Wisconsin, Inc., a Wisconsin corporation ("SPR
Wisconsin"), Systems and Programming Resources, Inc., an Illinois corporation
("Systems Inc."), and Consulting Acquisition, Inc., an Illinois corporation
("Data Flex"). Such mergers are each individually referred to in this Prospectus
as a "Merger" and collectively as the "Mergers." Unless indicated otherwise, the
information contained in this Prospectus: (i) gives retroactive effect to the
Mergers and (ii) assumes that the Underwriters' over-allotment option is not
exercised. Unless otherwise indicated, all references to "SPR" or the "Company"
refer to SPR Inc. after the Mergers or to the constituent corporations in the
Mergers or their respective predecessors, as appropriate. See "Certain
Transactions."
 
                                  THE COMPANY
 
     SPR has over 23 years of experience in providing information technology
("IT") services to clients in a variety of industries, including financial
services, healthcare, insurance, manufacturing, oil and gas, transportation and
utilities. The Company focuses its marketing efforts on Fortune 1000 companies
and other large organizations which have complex IT operations and significant
IT budgets. Over the past several years, the Company has shifted its focus from
contract programming to strategic planning and project management engagements.
SPR currently provides the following service offerings: (i) General Consulting,
(ii) Systems Re-engineering, (iii) Century Date Compliance, (iv) Systems
Maintenance and Support and (v) Information Delivery Services ("IDS"). Within
each of these service offerings, the Company provides three levels of consulting
support which are distinguished by the degree of responsibility the Company
assumes: strategic planning, project management and implementation. The Company
believes that this breadth of service and support fosters long-term client
relationships, promotes cross-selling opportunities and minimizes the Company's
dependence upon any particular service offering or client.
 
     The Company's proprietary service methodologies, Renovation(SM) and
Renovation2000(SM), and its software analysis tool, CodeVu(SM), provide SPR with
a disciplined approach to fulfill its engagements. Renovation(SM) and
Renovation2000(SM) enable the Company to deliver its service offerings through a
tested and repeatable format. CodeVu(SM) quickly and accurately provides
information concerning client software portfolios. These service methodologies
coupled with this software analysis tool facilitate the development of
well-defined tasks and timetables for each phase of an engagement from strategic
planning through implementation.
 
     Due to the complex nature of information technology, the rapidly changing
technological environment and the year 2000 problem (the software glitch that
will prevent computers from properly recognizing dates after the year 1999),
many organizations are outsourcing their IT needs. The Company believes this
outsourcing trend will continue to grow because: (i) organizations desire to
focus their energies on their core business functions; (ii) organizations must
address and resolve the year 2000 problem; (iii) IT solutions are becoming
increasingly complex; and (iv) organizations often lack the IT skills necessary
to address their IT needs.
 
     Total expenditures for professional IT services in the United States are
estimated to be $54.1 billion in 1996. The professional IT services market,
consisting of consulting and education, systems integration and development and
systems management services, is expected to grow at a compound annual growth
rate of approximately 14% over the next three years, reaching $79.6 billion by
1999. Large organizations, which make up the Company's primary target market,
are expected to constitute approximately 46% of total expenditures in this
market in 1996. The estimated cost in the United States to correct the year 2000
problem associated with software and databases is expected to be approximately
$130 billion.

     The Company's objective is to become the leading IT service provider to
both new and existing clients. To achieve this objective, the Company has
pursued, and intends to continue to pursue, the following business and growth
strategies:
 
     - Focus on Project Management. The Company will continue to focus on
      increasing its mix of project management and strategic planning
      engagements. The Company believes that by providing these value-added
      services, it gains a competitive advantage in assessing its clients' needs
      and anticipating opportunities to provide additional IT services.
 
     - Attract, Develop and Retain Qualified Technical Consultants. The Company
      has implemented a comprehensive entry-level training program for college
      graduates to address the industry-wide shortage of qualified technical
      consultants. In addition, the Company is developing several other training
      programs to further enhance its consultants' careers and improve their
      technical skills. SPR believes that these training programs and its
      recently established stock option and stock purchase plans will help it to
      attract, develop and retain consultants.
 
     - Capitalize on Century Date Compliance Expertise. SPR was an early entrant
      in the year 2000 segment of the market, completing its first Century Date
      Compliance engagement in 1993. The Company believes that its expertise in
      addressing the year 2000 problem will not only result in additional
      engagements, but that such engagements also will provide SPR with insight
      into its clients' IT environments, resulting in a competitive advantage in
      cross-selling additional IT services.
 
     - Deliver Unbiased Service Offerings. The Company uses Renovation(SM),
      Renovation2000(SM) and CodeVu(SM) in conjunction with the best available
      third-party application software and productivity tools without regard to
      specific third-party vendor relationships. The ability to assess client
      systems objectively enables the Company to provide its clients with
      technologies that are best suited to their individual needs.
 
     - Focus on Leading Technologies. The Company maintains and continues to
      build expertise not only in mainframe applications but also in other high
      demand technologies, such as Internet/intranet applications, open
      computing systems, object oriented solutions and relational database
      management systems. The Company's expertise in these areas, together with
      its relationships with software product developers and research
      institutions, allow SPR to remain on the leading edge of technological
      development.
 
     - Leverage Existing Client Base and Expand Client Services. The Company
      intends to continue building long-term client relationships by developing
      and expanding the services it provides to existing clients. For example,
      the Company began the development of its IDS service offering in 1995 and
      established its first Virtual Insourcing Center, which enables the Company
      to provide the full range of its service offerings in a Company facility
      rather than at its clients' facilities, in 1996 in response to its clients
      changing IT service needs.
 
     SPR's growth strategies have allowed it to capitalize on the growing demand
for IT services. The Company's revenues have increased at a compound annual
growth rate of approximately 36% from 1992 through 1995. For the ten months
ended October 31, 1996, the Company's revenues increased 44% compared with the
same period in the prior year. More than 71% of the Company's revenues for the
ten months ended October 31, 1996 were attributable to 37 companies which have
been clients for three consecutive years or longer. During 1996, the Company has
made significant infrastructure investments, which adversely affected the
Company's gross profit and operating income, in order to satisfy anticipated
future demand for the Company's service offerings. These investments included
(i) the development and implementation of the Company's entry-level training
program, (ii) the hiring of 235 IT consultants, 20 project managers, seven
recruiters, a Chief Financial Officer, a General Manager for the Company's Texas
branch office and a Director of Human Resources, (iii) the establishment of, and
initial staffing to support, the IDS service offering, (iv) the leasing of new
office space in Chicago and Wisconsin and (v) the enhancement of the Company's
proprietary methodologies and software analysis tool.

- -------------------------
(1) In October 1996, Systems Inc., SPR Chicago, SPR Tulsa, SPR Wisconsin and
    Data Flex merged into SPR and, in connection therewith, the stockholders of
    such companies received an aggregate of 6,333,134 shares of Common Stock of
    SPR. The financial data above has been restated to include the financial
    position and results of operations of the respective companies for all
    periods presented.
 
(2) In 1994, Systems Inc. transferred certain assets and liabilities to SPR
    Chicago and SPR Wisconsin. Inasmuch as such 1994 transactions were among
    family members within a control group, such transactions have been recorded
    in the Company's financial statements as if the stockholders of SPR Chicago
    and SPR Wisconsin received non-cash, stock-based compensation during 1994,
    1995 and 1996 in an amount equal to the increase in the estimated value of
    such companies since 1994. This expense is non-recurring subsequent to
    October 31, 1996. Such compensation expense is recorded as stock-based
    compensation with the corresponding credit included in additional paid-in
    capital. Upon conversion of the Company to a C corporation upon closing of
    the Offering, the retained deficit of the Company, which includes the
    aggregate stock-based compensation expense, will be reclassified and netted
    against additional paid-in capital. Excluding such compensation expense, net
    income for 1995 and the ten months ended October 31, 1995 and 1996 on a pro
    forma basis would have been $1.6 million, $1.5 million and $0.9 million,
    respectively. See "-- Summary Unaudited Pro Forma Financial Data" and Note
    10 of Notes to Financial Statements.

                   SUMMARY UNAUDITED PRO FORMA FINANCIAL DATA
 
     The Summary Unaudited Pro Forma Financial Data are based on the historical
financial statements of the Company, giving effect to the Offering and to the
pro forma adjustments described in the accompanying notes as if the Offering
occurred as of January 1, 1995 in the case of the Statement of Operations Data
and October 31, 1996 in the case of the Balance Sheet Data. The Unaudited Pro
Forma Financial Data are not necessarily indicative of the results of operations
which would have been achieved had the Offering occurred on January 1, 1995 nor
are they necessarily indicative of the results of future operations. The
Unaudited Pro Forma Financial Data should be read in conjunction with the
financial statements of the Company included elsewhere in this Prospectus.

</TABLE>
 
- -------------------------
(1) In 1994, Systems Inc. transferred certain assets and liabilities to SPR
    Chicago and SPR Wisconsin. Inasmuch as such transactions were among family
    members within a control group, such transactions have been recorded in the
    Company's financial statements as if the stockholders of SPR Chicago and SPR
    Wisconsin received non-cash, stock-based compensation during 1994, 1995 and
    1996, in an amount equal to the increase in the estimated value of such
    companies since 1994. This expense is non-recurring subsequent to October
    31, 1996. The Summary Unaudited Pro Forma Financial Data eliminates such
    expense from operating income for the year ended December 31, 1995 and for
    the ten months ended October 31, 1995 and October 31, 1996; accordingly,
    operating income for such periods was increased by $28.0 million, $23.3
    million and $15.9 million, respectively. See Note 10 of Notes to Financial
    Statements.
 
(2) Prior to the Offering, the Company was an S corporation and was not subject
    to Federal and certain state corporate income taxes. The Statement of
    Operations Data reflects a pro forma provision for income taxes as if the
    Company had been subject to Federal and state corporate income taxes for all
    periods. The pro forma provision for income taxes represents a combined
    Federal and state effective tax rate of 40%.
 
(3) Adjusted to reflect the application of the estimated net proceeds from the
    Offering, estimated to be $22.6 million (assuming an initial public offering
    price of $15 per share). The proceeds from the Offering will be used to pay
    the Dividend (see note 4), pay a stockholder note, borrowings under a line
    of credit and a term note and for general corporate purposes.
 
(4) Immediately prior to consummation of the Offering, the Company intends to
    declare a dividend (the "Dividend") to enable the stockholders of record
    prior to the Offering to pay income taxes related to S corporation income
    prior to the Offering. The Company currently estimates (based in part on the
    Company's estimate of its 1996 earnings) that the Dividend will be $2.5
    million.
 
(5) Upon conversion of the Company to a C corporation at the closing of the
    Offering, the Company will record $0.6 million in estimated deferred income
    tax liabilities which will reduce retained earnings and increase
    liabilities. Retained deficit of the Company (including the stock-based
    compensation expense), after recording the estimated Dividend and deferred
    income taxes, will be reclassified and netted against additional paid-in
    capital.

                                  RISK FACTORS
 
     Prospective purchasers of the Common Stock offered hereby should consider
carefully the risks associated with investing in the Common Stock, including the
principal risk factors set forth below, as well as other information set forth
in this Prospectus.
 
NEED TO ATTRACT AND RETAIN QUALIFIED TECHNICAL CONSULTANTS
 
     The Company's business involves the delivery of professional services and
is very labor-intensive. The Company's success depends in large part upon its
ability to attract, develop, motivate and retain qualified technical
consultants, particularly project managers and other senior technical personnel.
Qualified technical consultants are in great demand and are likely to remain a
limited resource for the foreseeable future. This demand may enable qualified
technical consultants to command significantly greater compensation than is
currently paid by the Company. There can be no assurance that the Company will
be able to continue to attract and retain a sufficient number of qualified
technical consultants in the future. Historically, the Company has experienced
turnover rates which it believes are consistent with industry norms. As
competition for qualified technical consultants increases, there can be no
assurance that the turnover rate experienced by the Company will not increase.
The Company's inability to hire sufficient qualified technical consultants, or a
significant increase in the Company's consultant turnover rate, could have a
material adverse effect on the Company's business, financial condition and
results of operations. See "Business -- Business Strategies."
 
MANAGEMENT OF GROWTH
 
     The Company's rapid revenue and employee growth has placed, and could
continue to place, significant demands upon its management and other resources.
To manage its growth effectively, the Company will be required to continue to
develop and improve its operational, financial and other internal systems, as
well as its business development capabilities. In addition, the Company's future
success will depend in large part upon its ability to maintain high rates of
consultant utilization and maintain the quality of its services. Moreover, none
of the Company's senior management has any experience managing a public company.
The Company's inability to manage its growth and engagements effectively could
have a material adverse effect on the Company's business, financial condition
and results of operations. See "-- Need to Attract and Retain Qualified
Technical Consultants" and "Management's Discussion and Analysis of Financial
Condition and Results of Operations."
 
RELIANCE ON CENTURY DATE COMPLIANCE ENGAGEMENTS
 
     Over the next few years, the Company expects to derive a majority of its
revenues from Century Date Compliance engagements. Market demand for Century
Date Compliance services will likely decrease substantially, and eventually
cease, during and after the year 2000. In addition, the Company's growth
strategy is substantially dependent upon leveraging its Century Date Compliance
experience to obtain other consulting engagements from its Century Date
Compliance clients. The Company's inability to consistently complete Century
Date Compliance engagements to its clients' satisfaction or to procure
additional consulting engagements from such clients could have a material
adverse effect on the Company's business, financial condition and results of
operations. In addition, there can be no assurance that a fully-automated
solution to the year 2000 problem (a "silver bullet") will not be developed. The
development of such a solution would have a material adverse effect on the
Company's business, financial condition and results of operations.
 
COMPETITION
 
     The highly competitive market for IT services includes a large number of
competitors and is subject to rapid change. The Company believes its primary
competitors include "Big Six" accounting firms, systems consulting and
implementation firms, application software firms, service groups of computer
equipment companies, general management consulting firms and programming
companies. Many of these competitors have significantly greater financial,
technical and marketing resources and greater name recognition than the Company.
In addition, the Company competes with its clients' internal IT personnel who
typically represent a
 
                                        8
<PAGE>   10
 
fixed cost to the client. Such competition may impose additional pricing
pressures on the Company. There can be no assurance that the Company can compete
successfully with its existing competitors or with any new competitors. See
"Business -- Competition."
 
ENGAGEMENT AND CONTRACT RISKS
 
     Many of the Company's engagements involve projects that are critical to the
operations of its clients' businesses. The Company's failure or inability to
complete engagements to its clients' satisfaction could have a material adverse
effect on its clients' operations and could consequently subject the Company to
litigation or damage the Company's reputation, which could have a material
adverse effect on the Company's business, financial condition and results of
operations.
 
     Substantially all of the Company's contracts are terminable by the client
on relatively short notice, with or without cause and without penalty. The
unexpected termination by a client of a significant contract could have a
material adverse effect on the Company's consultant utilization rate which, in
turn, could have a material adverse effect on the Company's business, financial
condition and results of operations. The Company principally bills for its
services on a "time and materials basis;" however, some of the Company's
contracts contain a cap on the amount of fees the Company can charge. In
addition, the Company currently is performing services for several of its
significant clients pursuant to oral agreements or written contracts that are no
longer in effect. In the event of a dispute, the absence of a written and
binding agreement limiting the Company's liability to the client could have a
material adverse effect on the Company's business, financial condition and
results of operations. Some of the Company's contracts give its clients the
right in certain circumstances to hire consultants employed or retained by the
Company, and several clients have, in fact, hired Company consultants in the
past. The loss of one or more project managers or a significant number of
qualified technical consultants to the Company's clients could have a material
adverse effect on the Company's business, financial condition and results of
operations. See "Management's Discussion and Analysis of Financial Condition and
Results of Operations."
 
CUSTOMER CONCENTRATION
 
     The Company has derived, and believes that it will continue to derive, a
significant portion of its revenues from a limited number of large clients. In
1995 and for the ten months ended October 31, 1996, the Company's largest client
accounted for approximately 11% and 16% of its revenues, respectively, and its
ten largest clients accounted for approximately 51% and 52% of its revenues,
respectively. The volume of work performed for specific clients varies from year
to year. There can be no assurance that a large client in one year will continue
to use the Company's services in a subsequent year. Furthermore, the Company
rarely is the exclusive provider of IT consulting services to its clients. The
loss of any large client could have a material adverse effect on the Company's
business, financial condition and results of operations.
 
RISKS OF BRANCH EXPANSION
 
     The Company anticipates future growth through branch expansion, which is
dependent upon a number of factors, including, but not limited to: (i) the
ability to cultivate additional business from existing clients and obtain new
clients; (ii) the ability to identify and hire qualified IT consultants within
both new and existing markets; and (iii) the continued identification and
training of corporate personnel to open and staff additional branch offices. The
Company has not opened a new branch office since 1979; however, the Company has
hired a general manager for the Texas region and is planning to open a branch
office in Texas in early 1997. There can be no assurance that new branch offices
will be profitable. See "-- Need to Attract and Retain Qualified Technical
Consultants."
 
INTELLECTUAL PROPERTY RIGHTS
 
     Software developed by SPR in connection with a client engagement typically
becomes the exclusive property of the client. Although the Company believes that
its services and the software it develops for its clients do not infringe upon
the intellectual property rights of others and that it has all rights necessary
to
 
                                        9
<PAGE>   11
 
utilize the intellectual property employed in its business, the Company is
subject to the risk of litigation alleging infringement of third-party
intellectual property rights. The Company typically agrees to indemnify its
clients against such claims. Any such claims could require the Company to spend
significant sums in litigation, pay damages, develop non-infringing intellectual
property or acquire licenses to the intellectual property which is the subject
of asserted infringement.
 
     The Company relies upon a combination of nondisclosure and other
contractual arrangements and trade secret, copyright and trademark laws to
protect its rights, the rights of third parties from whom the Company licenses
intellectual property and the proprietary rights of its clients. The Company
requires all consultants to sign confidentiality agreements and limits
distribution of proprietary information. There can be no assurance, however,
that the steps taken by the Company will be adequate to deter misappropriation
of proprietary information or that the Company will be able to detect
unauthorized use and take appropriate steps to enforce its intellectual property
rights. See "Business -- Intellectual Property Rights."
 
RELIANCE UPON EXECUTIVE OFFICERS AND KEY EMPLOYEES
 
     The success of the Company is highly dependent upon the efforts and
abilities of its executive officers, particularly Mr. Robert Figliulo, the
Company's President. Although all of its executive officers and certain key
employees have entered into employment agreements with the Company which contain
noncompetition, nondisclosure and nonsolicitation covenants, such agreements do
not guarantee that these individuals will continue their employment with the
Company. The loss of the services of any of these executive officers or key
employees for any reason could have a material adverse effect upon the Company's
business, financial condition and results of operations. See "Management --
Employment Agreements."
 
CONTROL BY PRINCIPAL STOCKHOLDERS
 
     After giving effect to the Offering, members of the Figliulo family, in the
aggregate, Michael Fletcher and Rene Potter will beneficially own approximately
50.5%, 8.1% and 7.7%, respectively, of the outstanding shares of Common Stock.
As a result, such persons collectively will be able to control the outcome of
matters requiring a stockholder vote, including the election of directors. Such
control could preclude any unsolicited acquisition of the Company and,
consequently, adversely affect the market price of the Common Stock. See
"Principal and Selling Stockholders" and "Description of Capital Stock --
Delaware Law and Certain Certificate of Incorporation and By-law Provisions;
Antitakeover Effects."
 
VARIABILITY OF QUARTERLY OPERATING RESULTS
 
     The Company's revenues and earnings have fluctuated and, in the future, may
fluctuate from quarter to quarter based on such factors as the number, size and
scope of projects in which the Company is engaged, the contractual terms and
degree of completion of such engagements, any delays incurred in connection with
an engagement, employee utilization rates, the adequacy of provisions for
losses, the accuracy of estimates of resources required to complete ongoing
engagements, and general economic conditions. Unanticipated variations in the
number, or progress toward completion, of the Company's engagements or in
consultant utilization rates may cause significant variations in operating
results in any particular quarter and could result in losses for such quarter.
An unanticipated termination of a major engagement, a client's decision not to
proceed to the stage of the engagement anticipated by the Company or the
completion during a quarter of several major client engagements, could leave the
Company with underutilized consultants which could have a material adverse
effect on the Company's business, financial condition and results of operations.
See "Management's Discussion and Analysis of Financial Condition and Results of
Operations."
 
EMPLOYMENT LIABILITY RISKS
 
     The Company generally places its consultants in the workplaces of other
businesses. Risks of such placement include possible claims of errors and
omissions, misuse of client proprietary information, misappropriation of funds,
discrimination and harassment, theft of client property, other criminal activity
or torts and other claims. Although historically the Company has not experienced
any material claims of these
 
                                       10
<PAGE>   12
 
types, there can be no assurance that the Company will not experience such
claims in the future. To reduce its exposure, the Company maintains insurance
covering general liability, workers' compensation claims, errors and omissions
and employer practices liability. There can be no assurance, however, that the
Company's insurance will cover all such claims, or that such insurance coverage
will continue to be available economically in amounts adequate to cover any such
liability or that such coverage will adequately compensate the Company for such
liabilities.
 
RISKS OF LICENSING CENTURY DATE COMPLIANCE METHODOLOGY
 
     The Company has entered into a non-exclusive agreement to license its
Century Date Compliance methodology, Renovation2000(SM), and its software
analysis tool, CodeVu(SM), to an unaffiliated technical services company
operating in New York and other markets where the Company is not currently doing
business. The Company may in the future enter into similar licensing agreements
with other third parties in specific geographic regions in which it does not
presently conduct business. There can be no assurance that such licensees will
properly utilize the Company's methodology or software analysis tool. The
failure by licensees to adhere strictly to SPR's standards in utilizing the
Renovation2000(SM) methodology or CodeVu(SM) in Century Date Compliance
engagements could subject SPR to litigation and harm SPR's reputation thereby
resulting in a material adverse effect on the Company's business, financial
condition and results of operations.
 
ABSENCE OF PRIOR PUBLIC MARKET; POSSIBLE VOLATILITY OF STOCK PRICE
 
     Prior to the Offering, there has not been a public market for the Common
Stock and there can be no assurance that an active trading market will develop
or be sustained after the Offering. The initial public offering price for the
Common Stock offered hereby will be determined by negotiations between the
Company and the representatives of the Underwriters, and may not be indicative
of the market price for the Common Stock after the Offering. See "Underwriting"
for a discussion of factors to be considered in determining the initial public
offering price. There can be no assurance that the market price of the Common
Stock will not decline below the initial public offering price. The Company
believes that variations in the Company's results of operations and other
factors, including general economic conditions, may cause the market price of
the Common Stock to fluctuate significantly. The market price for the Common
Stock may also be affected by the Company's ability to meet analysts'
expectations, and any failure to meet such expectations, even if minor, could
have a material adverse effect on the market price of the Common Stock. In
addition, from time to time in recent years, the securities markets have
experienced significant price and volume fluctuations that have often been
unrelated or disproportionate to the operating performance of particular
companies. Following the Offering, sales or the expectation of sales of
substantial amounts of Common Stock in the public market by the Company or its
stockholders also could adversely affect the prevailing market prices for the
Common Stock. See "Underwriting."
 
IMMEDIATE AND SUBSTANTIAL DILUTION
 
     The assumed initial public offering price is substantially higher than the
pro forma net tangible book value per share of Common Stock. Investors
purchasing shares of Common Stock in the Offering will therefore incur immediate
and substantial dilution of $12.20 per share of Common Stock based on an assumed
initial public offering price of $15.00 per share. To the extent options to
purchase Common Stock that are expected to be outstanding upon closing of the
Offering are exercised, there will be further dilution. See "Dilution."
 
SIGNIFICANT UNALLOCATED NET PROCEEDS
 
     The only specific allocations of the Company's anticipated net proceeds
from the Offering is the payment to existing stockholders of the Dividend,
repayment of certain indebtedness, including a note payable to Eugene Figliulo,
the founder of the Company's predecessor, and bank loans, funding of additional
consultant training and costs associated with the development and expansion of
off-site service centers (the "Virtual Insourcing Centers"). See "Business --
Growth Strategies -- Further Develop Virtual Insourcing Centers." Accordingly, a
substantial majority of the Company's anticipated net proceeds of the Offering
has not been
 
                                       11
<PAGE>   13
 
designated for specific uses. The Board of Directors of the Company will have
broad discretion with respect to the use of such unallocated net proceeds. See
"Use of Proceeds."
 
ANTI-TAKEOVER PROVISIONS
 
     The Company's Certificate of Incorporation and By-laws and the Delaware
General Corporation Law contain certain provisions that could have the effect of
discouraging or making more difficult the acquisition of the Company by means of
a tender offer, a proxy contest or otherwise, even though such an acquisition
might be economically beneficial to the Company's stockholders. These include
provisions under which (i) only the Chairman of the Board or the President may
call meetings of stockholders, and (ii) stockholders must comply with certain
advance notice procedures to nominate candidates for election as directors of
the Company and to submit proposals for consideration at stockholders' meetings.
The ability of the Board of Directors to issue up to 3,000,000 shares of
preferred stock, in one or more classes or series, and with such powers,
designations, preferences and relative, participating, optional or special
rights, qualifications, limitations or restrictions as may be determined by the
Board of Directors of the Company, also could make an acquisition of the Company
more difficult. In addition, these provisions may make the removal of management
more difficult, even in cases where such removal would be favorable to the
interests of the Company's stockholders. See "-- Control by Principal
Stockholders," "Management -- Directors and Executive Officers" and "Description
of Capital Stock -- Delaware Law and Certain Certificate of Incorporation and
By-law Provisions; Anti-Takeover Effects."
 
SHARES ELIGIBLE FOR FUTURE SALE
 
     Upon completion of the Offering, the Company will have 8,000,000 shares of
Common Stock outstanding, of which the 2,700,000 shares sold pursuant to the
Offering will be freely transferable without restriction or further registration
under the Securities Act of 1933, as amended (the "Securities Act") (other than
by an "affiliate" of the Company, as defined in the Securities Act), and the
remaining 5,300,000 shares will be "restricted securities" under Rule 144 ("Rule
144") promulgated under the Securities Act. Holders of the restricted shares
will be eligible to sell such shares pursuant to Rule 144 at prescribed times
and subject to the manner of sale, volume, notice and information restrictions
of Rule 144. The Company has granted Messrs. Robert Figliulo, David Figliulo,
John Figliulo and Michael Fletcher an unlimited number of demand and piggyback
registration rights covering an aggregate of 532,184 shares of Common Stock. In
addition, 800,000 shares of Common Stock are reserved for issuance under the
Company's Combined Incentive and Non-statutory Stock Option Plan (the "Option
Plan") and 500,000 shares of Common Stock are reserved for issuance under the
Company's Employee Stock Purchase Plan. The Company intends to register under
the Securities Act all of the shares covered by the Option Plan and the Employee
Stock Purchase Plan, which shares upon issuance would become freely tradeable
without restriction. Each of (i) the Company, (ii) all of the Company's
executive officers and directors, and (iii) all stockholders of the Company
owning Common Stock immediately prior to the Offering have agreed not to offer,
sell, contract to sell or otherwise dispose of, any shares of Common Stock or
any securities convertible into or exchangeable or exercisable for Common Stock,
or grant any options or warrants to purchase Common Stock, except in certain
circumstances, for 180 days after the date of this Prospectus without the prior
consent of Smith Barney Inc., which agreements may be waived by Smith Barney
Inc. in its discretion. None of the 5,300,000 shares of Common Stock which are
restricted securities will be eligible for sale after the expiration of such
lock-up agreements until the applicable holding period under Rule 144 (currently
two years) has expired. Thereafter, all 5,300,000 shares of Common Stock which
are restricted securities will be eligible for sale subject to the provisions of
Rule 144. Following the Offering, sales or the expectation of sales of
substantial amounts of Common Stock in the public market could adversely affect
the prevailing market price for the Common Stock and the Company's ability to
raise additional capital at a price favorable to the Company. See "Shares
Eligible for Future Sale" and "Underwriting."

                                  THE COMPANY
 
     The Company's business was founded in 1973 by Eugene Figliulo as Systems
Inc. During 1994, Systems Inc. transferred certain assets and liabilities to SPR
Chicago, SPR Tulsa, and SPR Wisconsin, respectively. These entities were
organized as S corporations and owned by the executives primarily responsible
for the operations in each of these locations. SPR Chicago, SPR Tulsa, SPR
Wisconsin, Systems Inc. and Data Flex (an affiliated IT services company in a
complementary business) were merged into the Company upon the Company's
formation in October 1996. See "Certain Transactions."
 
     The Company maintains its principal executive offices at 2015 Spring Road,
Oak Brook, Illinois 60521. Its telephone number is (630) 990-2040. The Company's
World Wide Web address is www.sprinc.com.
 
                                USE OF PROCEEDS
 
     The net proceeds to the Company from the sale of the 1,666,666 shares of
Common Stock offered by it hereby (after deducting estimated underwriting
discounts and commissions and estimated offering expenses) are estimated to be
approximately $22.6 million, based upon an assumed initial public offering price
of $15.00 per share of Common Stock.
 
     The principal purposes of the Offering are to increase the Company's equity
capital and financial flexibility, create a public market for the Common Stock,
facilitate future access by the Company to the public equity markets, enhance
the Company's ability to use Common Stock as a means of attracting and retaining
key employees and technical staff, and provide working capital to fund the
Company's growth strategies. See "Business -- Growth Strategies" and "Business
- -- Recruiting and Training."
 
     The Company intends to use a portion of its net proceeds from the Offering
to pay existing stockholders of the Company the Dividend in an aggregate amount
of $2.5 million to enable such stockholders to pay Federal and state income
taxes due on S corporation taxable income through the closing date of the
Offering. See "Certain Transactions." In addition, the Company intends to use
approximately $0.8 million of its net proceeds to pay outstanding indebtedness
to Eugene Figliulo and approximately $0.8 million of such proceeds to pay
outstanding indebtedness under a line of credit and term note. See "Management's
Discussion and Analysis of Financial Condition and Results of Operations --
Liquidity and Capital Resources" for information regarding interest rates,
maturities and use of proceeds of indebtedness.
 
     Approximately $1.4 million of the net proceeds will be used to build-out
and equip an additional Virtual Insourcing Center and open a Texas branch
office. See "Business -- Growth Strategies -- Further Develop Virtual Insourcing
Centers" and "Business -- Growth Strategies -- Expand Geographic Presence." As
of October 31, 1996, the Company had not incurred, or made any commitments to
incur, significant capital expenditures with respect to either the additional
Virtual Insourcing Center or the Texas branch office.
 
     The Company intends to use the remaining net proceeds for general corporate
purposes, including the expansion of its entry-level recruiting and training
program. Pending any of the foregoing uses, the Company intends to invest the
net proceeds in short-term, investment grade securities, certificates of deposit
or direct or guaranteed obligations of the United States government. The Company
will not receive any proceeds from shares of Common Stock sold by the Selling
Stockholders.
 
                                DIVIDEND POLICY
 
     Except for distributions to stockholders to fund their payments of taxes
due on prior year S corporation income, the Company has not declared or paid any
cash dividends on the Common Stock. After the Offering, except for the Dividend,
the Company expects to retain any future earnings to finance the operation and
expansion of its business and does not anticipate paying any cash dividends on
its Common Stock in the foreseeable future. Any future determination as to the
payment of dividends will depend upon the results of operations, financial
condition, capital expenditure plans and other obligations of the Company and
will be at the sole discretion of the Company's Board of Directors.

     The following table sets forth the Company's long-term indebtedness and
capitalization as of October 31, 1996 and as adjusted to give effect to the sale
of 1,666,666 shares of Common Stock offered by the Company (at an assumed
initial public offering price of $15.00 per share) and the application of the
estimated net proceeds therefrom. The information set forth below should be read

    Employee Stock Purchase Plan. See "Management -- Stock Plans," "Description
    of Capital Stock" and Note 11 of Notes to Financial Statements.
 
(2) Immediately prior to closing of the Offering, the Company intends to declare
    the Dividend. The Company currently estimates (based in part on the
    Company's estimate of its 1996 earnings) that the Dividend will be $2.5
    million. Upon conversion of the Company to a C corporation at the closing of
    the Offering, the Company will record approximately $0.6 million in deferred
    income taxes which will reduce retained earnings and increase liabilities.
    Retained deficit of the Company (including the stock-based compensation
    expense), after recording the estimated Dividend and deferred income tax
    liabilities, will be reclassified and netted against additional paid-in
    capital in connection with the termination of the Company's S corporation
    election.

                                    DILUTION
 
     As of October 31, 1996, the Company's net tangible book value was
$2,925,800 or $.46 per share of Common Stock. Net tangible book value per share
represents the Company's total net tangible assets less total liabilities
divided by the number of shares of Common Stock outstanding. Without taking into
account any other changes in net tangible book value after October 31, 1996,
other than to give effect to the Company's receipt of its portion of the
estimated net proceeds of the Offering, at an assumed initial public offering
price of $15.00 per share, the payment of the Dividend and the recording of
deferred taxes of approximately $600,000, the pro forma net tangible book value
of the Company on October 31, 1996 would have been $22,375,790 or $2.80 per
share. This represents an immediate increase in net tangible book value to the
existing stockholders of approximately $2.83 per share and an immediate dilution
to purchasers of shares of Common Stock in the Offering of $12.20 per share, as
illustrated by the following:

    there will be further dilution to new investors.
 
(2) The above table is based on ownership as of October 31, 1996. Sales by
    Selling Stockholders in the Offering will reduce the number of shares held

    shares of Common Stock outstanding after the Offering (61.2% if the
    Underwriters' over-allotment option is exercised in full), and will increase
    the number of shares held by new investors to 2,700,000 shares or 33.7% of
    the total number of shares of Common Stock outstanding after the Offering
    (38.8% if the Underwriters' over-allotment option is exercised in full). See

                            SELECTED FINANCIAL DATA
 
     The following selected financial data should be read in conjunction with
the Financial Statements of the Company and notes thereto. The Statement of
Operations Data and Balance Sheet Data for, and as of, the end of each of the
years in the three year period ended December 31, 1995 are derived from the
audited Financial Statements of the Company. The Statement of Operations Data
and Balance Sheet Data for, and as of, the years ending December 31, 1991 and
December 31, 1992, and for, and as of, the end of each of the ten months ended
October 31, 1995 and October 31, 1996, have been derived from the unaudited
financial statements of the Company and in the opinion of management include all
adjustments (consisting of normal and recurring adjustments) which are necessary

(1) In October 1996, Systems Inc., SPR Chicago, SPR Tulsa, SPR Wisconsin and
    Data Flex merged into SPR and, in connection therewith, the stockholders of
    such companies received an aggregate of 6,333,134 shares of Common Stock of
    SPR. The financial data above has been restated to include the financial
    position and results of operations of the respective companies for all
    periods presented.
 
(2) In 1994, Systems Inc. transferred certain assets and liabilities to SPR
    Chicago and SPR Wisconsin. Inasmuch as such 1994 transactions were among
    family members within a control group, such transactions have been recorded
    in the Company's financial statements as if the stockholders of SPR Chicago
    and SPR Wisconsin received non-cash, stock-based compensation during 1994,
    1995 and 1996 in an amount equal to the increase in the estimated value of
    such companies since 1994. This expense is non-recurring subsequent to
    October 31, 1996. Such compensation expense is recorded as stock-based
    compensation with the corresponding credit included in additional paid-in
    capital. Upon conversion of the Company to a C corporation upon closing of
    the Offering, the retained deficit of the Company, which includes the
    aggregate stock-based compensation expense, will be reclassified and netted
    against additional paid-in capital. Excluding such compensation expense, net
    income for 1995 and the ten months ended October 31, 1995 and 1996 on a pro
    forma basis would have been $1.6 million, $1.5 million and $0.9 million,
    respectively. See "Prospectus Summary -- Summary Unaudited Pro Forma
    Financial Data" and Note 10 of Notes to Financial Statements.

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 
INTRODUCTION
 
     The following section of the Prospectus, Management's Discussion and
Analysis of Financial Condition and Results of Operations, contains certain
forward-looking statements that involve substantial risks and uncertainties.
"Expect" and similar expressions, as they relate to the Company or its
management, are intended to identify such forward-looking statements. The
Company's actual results, performance or achievements could differ materially
from the results, performance or achievements expressed in, or implied by, these
forward-looking statements. Factors that could cause or contribute to such
differences include those discussed in "Risk Factors."
 
COMPANY OVERVIEW
 
     The Company was founded in 1973 and derives its revenues from providing IT
consulting services. SPR principally bills its clients on a "time and materials
basis" and revenues are recognized as services are provided. Typically, the
Company bills for its services on a biweekly basis to monitor client
satisfaction and to manage its outstanding accounts receivable balances. The
Company's cost of services consists primarily of consultant compensation and
related expenses. Accordingly, the Company's financial performance is
substantially affected by billing margins (billable hourly rate less consultant
hourly cost) and consultant utilization rates (the ratio of hours billed to
total available hours).
 
     Historically, SPR has maintained its billing margins by increasing its
hourly rates to offset increases in its consulting staff costs. The Company
manages its billing margins by establishing a target billing rate for each
consultant; however, actual billing rates may be higher or lower than the target
billing rates depending upon competitive pressures and market conditions. Hourly
billing rate increases are generally implemented by the Company based upon
market conditions, consultant skill levels and the terms of its engagements.
 
     To date, the Company believes that it has effectively managed its
consultant utilization rates. Fluctuations in consultant utilization rates
result from variations in the amount of unassigned time, which historically has
consisted of training, vacation, sick and holiday time and time spent on
administrative support activities while between engagements. In order to reduce
unassigned time, the Company actively manages the terms of its engagements and
matches available consultants based upon client requirements. In addition, the
number of new consultant training programs and the amount of time it takes to
assign the newly trained consultants vary, thereby affecting the Company's
consultant utilization rates from period to period.
 
     The Company believes that its business and growth strategies are primarily
dependent upon the availability of qualified technical consultants. To address
the shortage of qualified technical consultants, the Company has developed a
three-year training program targeted at college graduates with degrees other
than computer science. This program begins with a six- to eight-week entry-level
course specifically geared to Century Date Compliance. Advanced course modules
are under development and will concentrate on the Company's other service
offerings. The individuals enrolled in the training program are paid a salary
commensurate with computer science graduates. Since the commencement of the
entry-level training program on February 15, 1996, 46 individuals have entered
and successfully completed entry-level training. The Company has incurred
approximately $969,000 in expenses attributable to such training program through
October 31, 1996, all of which have been expensed as incurred. These expenses,
which have adversely affected gross profit and operating income for the ten
months ended October 31, 1996, include approximately $223,000 of salaries and
benefits attributable to trainees during the period in which they were enrolled
in the training program, $365,000 of salaries and benefits attributable to these
individuals pending their assignment to billable engagements, $321,000 of other
training related expenses and $60,000 of recruiting expenses. As of October 31,
1996, 33 entry-level trainees have been assigned to client engagements, seven
will commence assignments prior to December 31, 1996 and six are expected to be
assigned in the near future. On November 4, 1996 the Company began an additional
entry-level training class of 14 individuals, and it intends to conduct
additional training classes on a regular basis in 1997. Since the costs of those
consultants completing the entry-level training program in 1996 have been fully
expensed in 1996, the Company believes
 
                                       17
<PAGE>   19
 
its operating profit should improve, in part, as a result of this investment.
The delay between the time consultants complete the entry-level training course
and the time they are assigned to billable engagements is expected to
significantly decrease as the demand for Century Date Compliance services and
the acceptance of entry-level consultants by the Company's clients grow.
 
     In 1994, Systems Inc. transferred certain assets and liabilities to SPR
Chicago and SPR Wisconsin. Inasmuch as such 1994 transactions were among family
members within a control group, such transactions have been recorded in the
Company's financial statements as if the stockholders of SPR Chicago and SPR
Wisconsin received noncash, stock-based compensation during 1994, 1995 and 1996.
This compensation expense was allocated to each such period based upon the
increase in the estimated fair market value of SPR Chicago and SPR Wisconsin
during the respective periods. This expense is non-recurring subsequent to
October 31, 1996. The pro forma financial data eliminates such expense from
operating income for 1995 and for the ten months ended October 31, 1995 and
October 31, 1996; accordingly, pro forma operating income reflects additional
income of $28.0 million and $23.3 million and $15.9 million, respectively. Upon
the conversion of the Company to a C corporation at closing of the Offering, the
retained deficit of the Company, which includes the aggregate stock-based
compensation expense, will be reclassified and netted against additional paid-in
capital.

(1) In 1994, Systems Inc. transferred certain assets and liabilities to SPR
    Chicago and SPR Wisconsin. Inasmuch as such transactions were among family
    members within a control group, such transactions have been recorded in the
    Company's financial statements as if the stockholders of SPR Chicago and SPR
    Wisconsin received non-cash, stock-based compensation during 1994, 1995 and
    1996, in an amount equal to the increase in the estimated value of such
    companies since 1994. This expense is non-recurring subsequent to October
    31, 1996. The Summary Unaudited Pro Forma Financial Data eliminates such
    expense from operating income for the year ended December 31, 1995 and for
    the ten months ended October 31, 1995 and October 31, 1996; accordingly,
    operating income for such periods was increased by $28.0 million, $23.3
    million and $15.9 million, respectively. See Note 10 of Notes to Financial
    Statements.
 
TEN MONTHS ENDED OCTOBER 31, 1996 COMPARED TO TEN MONTHS ENDED OCTOBER 31, 1995
 
     Revenues. Revenues increased 44% to $26.6 million in the first ten months
of 1996 from $18.5 million in the comparable 1995 period. This increase was
primarily the result of an increased number of engagements for
 
                                       18
<PAGE>   20
 
both new and existing clients. A higher proportion of these engagements were for
strategic planning and assessment for Century Date Compliance engagements, which
yield higher billing rates.
 
     Gross Profit. Gross profit consists of revenues less cost of services,
which includes consultant salaries and benefits. Gross profit increased 28% to
$7.8 million in the first ten months of 1996 from $6.1 million in the comparable
1995 period. Gross profit as a percentage of revenues decreased to 29% in the
first ten months of 1996 from 33% in the comparable 1995 period. The decrease in
gross margin was primarily attributable to costs relating to trainees enrolled
in the entry-level training program, and the subsequent delay in the assignment
of these individuals to billable engagements. This resulted in an increase in
expenses of approximately $0.6 million without any increase in revenues. In
addition, the Company hired 20 project managers (an increase of 200% from the
comparable 1995 period) to satisfy anticipated demand for the Company's
services. The Company's operating income for the ten months ended October 31,
1996 was adversely affected by the large number of project managers hired during
such period and the amount of time these project managers devoted to enhancing
the Company's proprietary methodologies and performing marketing and
administrative activities. The Company believes that operating income should
improve as these project managers devote more time to billable engagements.
 
     Selling Expenses. Selling expenses include the salaries, benefits,
commissions, bonuses, travel, entertainment and other direct costs associated
with the Company's direct sales force. Selling expenses increased 47% to $2.4
million in the first ten months of 1996 from $1.7 million in the comparable 1995
period. This increase was primarily the result of increased commissions
attributable to the 44% increase in sales over the comparable period. The
Company also had three more salespeople on October 31, 1996 than it had on
October 31, 1995. The Company's selling expenses, as a percentage of revenues,
were 9% in the first ten months of 1996 and 1995.
 
     Recruiting Expenses. Recruiting expenses consist of costs related to hiring
new personnel, which include the salaries, benefits, bonuses and other direct
costs of the in-house recruiters, consultant relocation fees, and advertising
costs. The Company hired 255 consultants during the first ten months of 1996
compared to 232 in the first ten months of 1995. Recruiting expenses increased
78% to $1.1 million in the first ten months of 1996 from $0.6 million in the
comparable 1995 period. This increase was the result of hiring seven additional
recruiters to manage the expanded hiring activity. As a result of such
additions, total recruiting costs per hire increased to approximately $4,300 in
the first ten months of 1996 from approximately $2,600 in the comparable 1995
period.
 
     General and Administrative Expenses. General and administrative expenses
include salaries and benefits of management and support staff, leased facilities
costs, training, non-billable travel, outside professional fees, depreciation
and all other corporate costs. General and administrative expenses increased
139% to $2.8 million in the first ten months of 1996 from $1.2 million in the
comparable 1995 period. This increase was primarily attributable to hiring six
additional employees, including a Chief Financial Officer, a General Manager for
the Company's Texas branch office, a Director of Human Resources, increased rent
relating to new office space in Chicago and Wisconsin, increased depreciation,
training costs associated primarily with outside instructors, and initial
staffing of the IDS business unit, including the reclassification of certain
employee salaries from cost of services and selling expenses to reflect the
change in responsibilities of these employees.
 
1995 COMPARED TO 1994
 
     Revenues. Revenues increased 55% to $22.9 million in 1995 from $14.8
million in 1994. The increase was primarily the result of an increased demand
for the Company's services from both new and existing clients and a continuing
shift from contract programming to project management engagements yielding
higher billing rates.
 
     Gross Profit. Gross profit increased 69% to $7.4 million in 1995 from $4.4
million in 1994. Gross profit as a percentage of revenues increased to 32% of
revenues in 1995 from 30% in 1994, resulting primarily from higher billing rates
without commensurate increases in consultant hourly costs resulting from the
shift from contract programming to project management and the completion of two
out-of-town engagements in 1994 in which per diem expenses were paid to
consultants but not passed through to clients. Out-of-town expenses,
 
                                       19
<PAGE>   21
 
such as travel expenses, generally are passed through to the Company's clients;
however, in the case of these two engagements, the Company agreed to bear such
expenses.
 
     Selling Expenses. Selling expenses increased 84% to $2.1 million in 1995
from $1.2 million in 1994. This increase was primarily the result of increased
commissions due to a 55% increase in sales in 1995 over 1994. In addition, the
Company hired four additional salespersons in 1995.
 
     Recruiting Expenses. Recruiting expenses increased 89% to $0.8 million in
1995 from $0.4 million in 1994. This increase was the result of hiring seven
additional recruiters to expand hiring activity required by the increased demand
for the Company's service offerings. The Company hired 254 consultants in 1995
compared to 168 in 1994. As a result of hiring the additional recruiters, total
recruiting costs per hire increased to approximately $3,100 in 1995 from
approximately $2,400 in 1994.
 
     General and Administrative Expenses. General and administrative expenses
increased 23% to $1.6 million in 1995 from $1.3 million in 1994. This increase
was primarily due to management salary and bonus increases, the hiring of a
Director of Human Resources, four general office staff employees and an increase
in depreciation. General and administrative expenses as a percentage of revenues
decreased to 7% in 1995 from 9% in 1994 as a result of the rapid growth in
revenues.
 
1994 COMPARED TO 1993
 
     Revenues. Revenues increased 26% to $14.8 million in 1994 from $11.7
million in 1993. The increase was primarily the result of an increased number of
engagements for both new and existing clients and a shift from contract
programming to project management engagements yielding higher billing rates.
 
     Gross Profit. Gross profit increased 29% to $4.4 million in 1994 from $3.4
million in 1993. Gross profit as a percentage of revenues increased to 30% of
revenues in 1994 from 29% in 1993. This percentage of revenues increase in 1994
over 1993 was attributable to higher billing rates without commensurate
increases in consultant hourly costs resulting from the shift from contract
programming to project management.
 
     Selling Expenses. Selling expenses increased 15% in 1994 to $1.2 million
from $1.0 million in 1993. This increase was primarily the result of increased
commissions due to the 26% increase in sales in 1994 over 1993. In addition, the
Company also hired a salesperson in 1994.
 
     Recruiting Expenses. Recruiting expenses increased 20% to $0.4 million in
1994 from $0.3 million in 1993. The Company hired 168 consultants in 1994
compared to 145 in 1993. Total recruiting costs per hire stayed approximately
the same at $2,400 in both periods.
 
     General and Administrative Expenses. General and administrative expenses
increased 9% to $1.3 million in 1994 from $1.2 million in 1993. This increase is
primarily due to increases in management bonuses resulting from increased sales.
General and administrative expenses as a percentage of revenues decreased to 9%
in 1994 from 10% in 1993, attributable to leveraging the rapid growth in
revenues.

LIQUIDITY AND CAPITAL RESOURCES
 
     The Company has financed its growth principally through cash flows from
operations. The Company's primary source of liquidity is the collection of its
accounts receivable. Accounts receivable have grown as the Company's operations
have grown. Receivables increased to 42 days of revenues at October 31, 1996
from 40 days of revenues at October 31, 1995. The Company's ability to reduce
significantly the aging of its outstanding receivables is limited because of a
continuing general trend by clients to slow their payment of invoices.
 
     Cash flow provided by operating activities, primarily to fund the growth in
accounts receivable, totaled $1.3 million and $1.6 million for the ten months
ended October 31, 1996 and 1995, respectively and $1.6 million, $1.3 million and
$0.6 million for the years ended December 31, 1995, 1994, and 1993,
respectively. Cash provided by (used in) the Company's investing activities,
primarily to fund capital expenditures, totaled ($0.7) million and $0.1 million
for the ten months ended October 31, 1996 and 1995, respectively, and ($0.1
million), ($0.2 million) and ($0.5 million) for the years ended December 31,
1995, 1994, and 1993, respectively. Net cash (used in) financing activities
consisted primarily of payments on a note payable to Eugene Figliulo and
dividend distributions totaled ($1.1 million) for the ten months ended October
31, 1996 and ($1.5 million) for the ten months ended October 31, 1995 and ($1.5
million), ($0.4 million) and ($0.1 million) for the years ended December 31,
1995, 1994 and 1993, respectively.
 
     The Company has supplemented cash generated by operations periodically with
short-term borrowings under lines of credit and a term loan. The proceeds from
the Company's $0.3 million term loan funded furniture and equipment purchases
for the Company's Chicago facility. The note matures on December 31, 2000, bears
interest at 9% per annum, with principal and interest payable monthly, and is
secured by certain accounts receivable and other assets. As of October 31, 1996,
the term note had an outstanding balance of $0.2 million. The Company intends to
pay the term note with part of the net proceeds from the Offering.
 
     Due to the significant growth the Company has experienced, two lines of
credit were established in 1996. These lines of credit provide for maximum
borrowings of $1.5 million and are limited based upon a percentage of eligible
accounts receivable. On October 31, 1996 there was $0.6 million outstanding on
the lines. Interest rates on the lines of credit are at each of the respective
bank's prime rate and are collateralized by certain assets including accounts
receivable. One agreement, which provides for maximum borrowings of $1.0
million, expires in May 1997. The other agreement, which provides for maximum
borrowings of $0.5 million, has no expiration date.
 
     The Company believes that cash flow from operations, the net proceeds of
the Offering and available borrowings will be sufficient to meet its operating
needs and capital expenditures for the foreseeable future.

COMPANY OVERVIEW
 
     SPR has over 23 years of experience in providing IT services to clients in
a variety of industries, including financial services, healthcare, insurance,
manufacturing, oil and gas, transportation and utilities. The Company focuses
its marketing efforts on Fortune 1000 companies and other large organizations
which have complex IT operations and significant IT budgets. SPR's objective is
to become the leading IT services provider to both new and existing clients.
Over the past several years, the Company has shifted its focus from contract
programming to strategic planning and project management engagements. SPR
currently provides the following service offerings: (i) General Consulting, (ii)
Systems Re-engineering, (iii) Century Date Compliance, (iv) Systems Maintenance
and Support and (v) Information Delivery Services. Within each of these service
offerings, the Company provides three levels of consulting support which are
distinguished by the degree of responsibility the Company assumes: strategic
planning, project management and implementation. The Company believes that this
breadth of service and support fosters long-term client relationships, promotes
cross-selling opportunities and minimizes the Company's dependence upon any
particular service offering or client.
 
     The Company currently has three branch offices located in Chicago,
Milwaukee and Tulsa and approximately 400 IT consulting professionals, including
30 project managers and 36 independent contractors. The number of consultants
employed or retained by the Company as of October 31, 1996 was 35% greater than
at the end of 1995. The Company has made, and intends to continue to make,
significant investments in its systems infrastructure, recruiting organization,
training programs and marketing initiatives in an effort to sustain growth. SPR
intends to leverage these investments, as well as its operating expertise, by
opening additional branch offices. The Company recently hired a General Manager
to work with clients in Texas, where it plans to open a branch office in early
1997.
 
     SPR has capitalized on the growing demand for IT services. The Company's
revenues have increased at a compound annual growth rate of approximately 36%
from 1992 through 1995. For the ten months ended October 31, 1996, the Company's
revenues increased 44% compared with the same period in the prior year. More
than 71% of the Company's revenues for the ten months ended October 31, 1996
were attributable to 37 companies which have been clients for three consecutive
years or longer.
 
INDUSTRY OVERVIEW
 
     Dataquest Incorporated estimates total expenditures for professional IT
services in the United States to be $54.1 billion in 1996. The professional IT
services market, consisting of consulting and education, systems integration and
development and systems management services, is expected to grow at a compound
annual growth rate of approximately 14% over the next three years, reaching
$79.6 billion by 1999. According to International Data Corporation, large
organizations, which make up the Company's primary target market, are expected
to account for approximately 46% of total expenditures in this market in 1996.
 
     The Company's experience is that many of these organizations are finding it
increasingly difficult and costly to internally maintain their existing systems.
Management believes that over 75% of existing mainframe and mid-range systems
will still be in operation seven to ten years from now as businesses will
continue to require massive data storage capabilities and tremendous processing
power, which are most efficiently provided by mainframe technology. As providers
of IT services focus more on the client/server segment of the market, however,
fewer professionals possess the skills necessary to support and maintain
existing mainframe and mid-range systems. The Company believes these factors
provide it with a substantial growth opportunity within the IT services
industry.
 
     In addition, the Company believes that clients will continue to maintain
and improve their existing systems because: (i) existing systems represent an
enormous investment which may prove too risky and expensive to completely
replace; (ii) mainframe computing is increasingly being utilized in new ways as
Internet/intranet technologies develop; (iii) existing systems are critical to
the functioning of clients' businesses as they contain vital business knowledge
needed to build replacement systems; and (iv) regardless
 
                                       22
<PAGE>   24
 
of which front-end computing platform is utilized, clients still need to access
data resident in mainframe computers.
 
     The Company also is capitalizing on the substantial growth opportunity
created by the year 2000 problem, the software glitch that will prevent
computers from properly recognizing dates after the year 1999. Coding 19YY as YY
eliminates two characters from each date reference thereby preserving
substantial amounts of disk storage and memory. A date shown as YY/MM/DD
provides many calculation options within a system, such as age, interest
computations, inventory, materials planning, shelf life, shipping dates and
billing. The problem with this programming format is that in the year 2000, when
YY=00, none of the calculations can work properly. If corrections are not made
prior to January 1, 2000, computer systems may fail which could cause businesses
to stop functioning properly. This abbreviated date-coding format is prevalent
in core, mission-critical systems, which comprise millions of lines of computer
code in existing systems. The data used and generated by these systems are
heavily integrated into multiple files and databases. This data integration
typically results in thousands of interfaces, each of which must be analyzed,
changed and tested to correct the problem, while minimizing the impact on
ongoing operations. Capers Jones estimates the cost in the United States to
correct the year 2000 problem associated with software and databases to be $130
billion. In addition, Gartner Group, Inc. projects that by the end of 1997 only
20% of all systems in the world will be year 2000 compliant, and only 50% of
such systems will be year 2000 compliant by the end of 1999.
 
BUSINESS STRATEGIES
 
     The Company's objective is to become the leading IT service provider to
both new and existing clients. To achieve this objective, the Company has
pursued, and intends to continue to pursue, the following business strategies:
 
     FOCUS ON PROJECT MANAGEMENT TO DELIVER VALUE-ADDED IT SOLUTIONS. In recent
years, the Company has shifted its focus from contract programming to project
management and strategic planning engagements, such as Century Date Compliance,
Systems Re-engineering and IDS. The Company believes that by providing such
value-added services it develops in-depth knowledge of its clients' existing
systems and gains a competitive advantage in assessing its clients' needs with
respect to emerging technologies and providing additional IT services.
 
     ATTRACT, DEVELOP AND RETAIN QUALIFIED TECHNICAL CONSULTANTS. The Company
currently employs 14 full-time recruiters: six in Chicago, four in Tulsa and
four in Milwaukee. In addition, the Company employs one recruiting manager in
each location. Over the past 23 years, the Company has developed and refined an
internal recruiting database which facilitates rapid identification of
consultant candidates based upon skill and geographic location. To address the
shortage of qualified technical consultants, the Company is developing a
three-year training program. This program, targeted at college graduates with
degrees other than computer science, begins with a six- to eight-week
entry-level course specifically geared to Century Data Compliance. In addition,
the Company is developing several other training programs to enable its
consultants to enhance their careers and to improve their technical skills. See
"-- Recruiting and Training." To help retain experienced consultants, the
Company has established comprehensive employee welfare plans, and recently
implemented the Option Plan and the Employee Stock Purchase Plan. See
"Management -- Stock Plans."
 
     DELIVER UNBIASED SERVICE OFFERINGS UTILIZING DISCIPLINED METHODOLOGIES. The
Company works closely with its clients' IT personnel from the strategic planning
phase through the completion of an engagement. To increase productivity and
efficiency, the Company has developed specific proprietary service
methodologies, Renovation(SM) and Renovation2000(SM), and a software analysis
tool, CodeVu(SM). See "-- Proprietary Service Methodologies." In implementing
its methodologies, the Company utilizes the best available third-party
application software and productivity tools without regard to specific
third-party vendor relationships, thereby avoiding the bias resulting from
promoting third-party products. The Company is capable, therefore, of offering
its clients an objective assessment of the advantages and disadvantages of the
latest packaged software applications, platforms, operating systems and
productivity tools.
 
     FOCUS ON LEADING TECHNOLOGIES. The Company maintains and continues to build
expertise not only in mainframe applications but also in other high demand
technologies, such as Internet/intranet applications,
 
                                       23
<PAGE>   25
 
open computing systems, object oriented solutions and relational database
management systems. SPR has developed, and intends to continue developing,
relationships with software product developers and research institutions to
remain on the leading edge of technological development and to provide its
clients with technologies that are best suited to their individual needs.
 
GROWTH STRATEGIES
 
     Historically, the Company has grown by developing new service offerings and
expanding its client base. The Company may also pursue growth through selected
geographic branch expansion and strategic acquisitions. Management believes that
its strategies have positioned the Company to achieve continued growth in
revenues and earnings. Key elements of the Company's growth strategies include
the following:
 
     CAPITALIZE ON CENTURY DATE COMPLIANCE EXPERTISE. SPR was an early entrant
into the year 2000 segment of the market, completing its first Century Date
Compliance engagement in 1993. The Company has either completed or is in the
process of completing 25 Century Date Compliance assessments. Based upon such
assessments, the Company has been retained to implement 15 of its proposed
Century Data Compliance solutions and has successfully completed implementation
of five such solutions. The Company expects that its expertise in this industry
segment will result in additional Century Date Compliance engagements as the
year 2000 approaches. To date, the Company has found that many of its clients
request the Company not only to evaluate their Century Date Compliance needs,
but also to assess functional and technical quality in their application
portfolios and develop strategies for improvement. As a result of its Century
Date Compliance engagements, SPR expects to be strategically positioned to
provide additional IT services to clients who have already entrusted their core,
mission-critical systems to SPR.
 
     LEVERAGE EXISTING CLIENT BASE. The Company intends to continue building
long-term client relationships. Its record of customer satisfaction and expanded
service offerings have contributed to the Company's ability to increase the
revenues generated from existing clients. For the ten month's ended October 31,
1996, the Company derived more than 71% of its revenues from 37 clients to which
it had provided IT services in the prior three consecutive years. The Company
intends to further penetrate its existing client base by providing additional
service offerings.
 
     DEVELOP AND EXPAND CLIENT SERVICES. The Company believes there are
substantial opportunities for increasing revenues by developing and expanding
services offered to existing and prospective clients. In response to client
needs, SPR implemented its IDS service offering in the third quarter of 1995 and
established its first Virtual Insourcing Center in the third quarter of 1996.
IDS was introduced to provide end-users access to data locked within existing
systems. By incorporating technologies such as data warehousing, on-line
analytical processing ("OLAP"), data mining and the Internet/intranet, IDS helps
bridge the gap between modern technologies and existing systems. The Company's
Virtual Insourcing Centers augment its Systems Maintenance and Support service
offering and are logical extensions of the Company's Systems Re-engineering,
Century Date Compliance and General Consulting service offerings. See "-- Growth
Strategies -- Further Develop Virtual Insourcing Centers" and "-- Service
Offerings."
 
     EXPAND GEOGRAPHIC PRESENCE. Geographic expansion will be driven primarily
by the growing need to service existing clients' divisions or affiliates in new
geographic locations, such as Texas. The Company has hired a General Manager for
the Texas region and anticipates opening a Texas branch in early 1997. The
Company also may pursue strategic acquisitions either to expand its geographic
presence or to complement its existing service offerings.
 
     FURTHER DEVELOP VIRTUAL INSOURCING CENTERS. In order to capitalize on the
corporate trend towards outsourcing, the Company intends to continue developing
Virtual Insourcing Centers. Equipped with a variety of computer hardware,
software and networking technologies and systems, these centers enable the
Company to provide the full range of its service offerings in a Company facility
rather than at its clients' facilities. The Virtual Insourcing Centers also
enable the Company to assume off-site project management responsibilities and to
complete Century Date Compliance and Systems Re-engineering and Systems
Maintenance and Support engagements without interrupting its clients'
businesses. In addition, Virtual Insourcing Centers allow
 
                                       24
<PAGE>   26
 
the Company to implement the testing phases of its Renovation(SM) and
Renovation2000(SM) methodologies seven days a week, rather than only on weekends
when clients are not utilizing their systems.
 
SERVICE OFFERINGS
 
     Since its inception, the Company has provided technical personnel to
augment its clients' internal IT departments. Over the past several years,
however, the Company has focused its efforts on providing higher-end service
offerings. The Company's current service offerings include: (i) General
Consulting; (ii) Systems Re-engineering; (iii) Century Date Compliance; (iv)
Systems Maintenance and Support; and (v) IDS. The Company offers each of its
five service offerings either independently or as part of a comprehensive
solution and performs these services on a "time and materials" basis. Within
each of its service offerings, the Company provides three levels of consulting
support which are distinguished by the degree of responsibility the Company
assumes: strategic planning, project management and implementation. The amount
of responsibility assumed by the Company generally depends upon a client's
in-house capabilities and desire to outsource IT functions. Based upon client
needs, SPR can provide strategic planning, project management or implementation
either at its clients' facilities or off-site at SPR's Virtual Insourcing
Centers. See "-- Growth Strategies -- Further Develop Virtual Insourcing
Centers." SPR employs proven proprietary service methodologies and software
analysis tools to deliver these services. See "-- Proprietary Service
Methodologies."
 
              [GRAPHICS REGARDING THE COMPANY'S SERVICE OFFERINGS]
 
     GENERAL CONSULTING. General Consulting consists of providing technical
personnel with expertise across numerous computing platforms to augment clients'
internal IT departments. These services are provided on an as-needed basis and
cover a broad range of assignments including contract programming,
client-managed software development and maintenance engagements.
 
     SYSTEMS RE-ENGINEERING. Systems Re-engineering consists of software
portfolio analysis and assessment, code stabilization, code modularization,
language upgrades or conversions, business specification extraction and system
documentation. The Company re-engineers existing systems to create more
manageable and functional applications and transitions existing systems to
distributed client/server and networking systems. This service offering allows
the Company's clients to leverage their investments in existing systems through
analysis, improvement, redesign and reuse of applications.
 
     CENTURY DATE COMPLIANCE. Century Date Compliance consists of retrofitting
existing systems to address the date change coding problem that will be caused
by the year 2000. Century Date Compliance services
 
                                       25
<PAGE>   27
 
include high-level organizational assessment of a client's software portfolio
and organizational readiness, engagement planning and management and
implementation. See "-- Industry Overview."
 
     SYSTEMS MAINTENANCE AND SUPPORT. Systems Maintenance and Support consists
of providing the management, systems maintenance and support of all or part of
clients' existing IT applications. Using proprietary service methodologies and
tools, the Company provides transition planning, engagement management, program
maintenance and testing, production support and system improvements.
 
     INFORMATION DELIVERY SERVICES. IDS consists of accessing, analyzing and
managing data which currently resides in existing systems. The Company uses its
expertise with existing systems and emerging technologies to provide its clients
with the ability to retrieve and utilize data resident in existing systems which
would otherwise be inaccessible. Services provided within IDS include
information harvesting, information analysis and information publishing, which
incorporate technologies such as OLAP and the Internet/intranet.
 
PROPRIETARY SERVICE METHODOLOGIES
 
     The Company's proprietary service methodologies, Renovation(SM) and
Renovation2000(SM), and its software analysis tool, CodeVu(SM), provide SPR with
a disciplined approach to fulfill its engagements. Renovation(SM) and
Renovation2000(SM) enable the Company to deliver its service offerings through a
tested and repeatable format. CodeVu(SM) quickly and accurately provides
information concerning client software portfolios. These service methodologies
coupled with the software analysis tool facilitate the development of
well-defined tasks and timetables for each phase of an engagement from strategic
planning through implementation.
 
     RENOVATION(SM). Renovation(SM) was first used by the Company in 1988 for
Systems Re-engineering engagements. The methodology employs a four phase
approach: assessment, improvement, transformation and preservation. In the
assessment phase, the system is analyzed for architectural deficiencies and a
strategy is developed for correcting these deficiencies and transforming the
existing architecture. In the improvement phase, commercially available tools
and internally developed techniques are applied to implement the strategy
developed in the assessment phase. In the transformation phase, the newly
re-engineered system is transformed into a new architectural paradigm. In the
preservation phase, quality assurance procedures are developed. These procedures
are designed to help prevent the degradation of the system after the Systems Re-
engineering process is complete, thereby protecting the client's investment in
its existing systems.
 
     RENOVATION2000(SM). Renovation2000(SM) is SPR's methodology for Century
Date Compliance engagements. This methodology employs a repeatable process
which, in conjunction with the best available third-party application software
and productivity tools, analyzes, locates and retrofits all programs and data
affected by the absence of a century date field to permit processing of dates
after 1999. This methodology enables the Company to capture information allowing
the refinement of the process and the preparation of estimates and schedules
throughout the engagement.
 
     CODEVU(SM). CodeVu(SM), which runs on mainframe and personal computing
platforms, analyzes source code and provides quantitative information at the
program and system level. CodeVu(SM) provides insight regarding the technical
quality of the source code, identifies programs that are the most costly to
maintain and represent the highest risk and identifies and locates potential
problems hidden within the code. This tool has been used successfully by the
Company in a large number of engagements, including Systems Re-engineering,
Century Date Compliance and Systems Maintenance and Support. CodeVu(SM) is often
integrated into client environments to assist with the maintenance and
preservation of source code.
 
MARKETING AND SALES
 
     SPR marketing representatives are assigned to a limited number of accounts
in order to develop an in-depth understanding of each client's individual needs
and to build long-term client relationships. These representatives are
responsible for providing highly responsive service and ensuring that the
Company's service offerings achieve client objectives. In many instances, a
portion of SPR's marketing activity is carried out by senior Company executives.
 
                                       26
<PAGE>   28
 
     The Company employs a variety of business development and marketing
techniques to communicate directly with current and prospective clients,
including (i) various print and direct mail advertisements, (ii) participation
in print and live interviews, roundtable discussions and seminars, and (iii) a
World Wide Web site (www.sprinc.com). In addition, the Company believes that its
President and Chairman is recognized as an expert concerning the year 2000
problem. He has participated, often with other service providers, research
organizations and productivity tool and hardware companies, in print, television
and live interviews and seminars concerning this problem. The Company believes
these activities promote greater client awareness and enhance the SPR brand
name.
 
CLIENT BASE
 
     The Company serves clients in a diverse range of industries thereby
mitigating cyclical effects of any one industry or market. The Company derives
an additional level of diversification from certain of its clients. Different
operating divisions of a given client may utilize any one or several services
offered by SPR, which helps mitigate the risk of customer concentration. During
1995, SPR's ten largest clients accounted for approximately 51% of the Company's
revenues and Allstate Insurance Company accounted for approximately 11% of its
revenues.
 
     The following table shows selected clients, categorized by industry group,

EMPLOYEES
 
     As of October 31, 1996, the Company had approximately 400 IT consulting
professionals, of which 361 were employees and 36 were independent contractors.
Of these IT consulting professionals, 30 were project
 
                                       27
<PAGE>   29
 
managers. As of such date, the Company had 412 employees: 203, 127 and 82 in
Chicago, Tulsa and Milwaukee, respectively.
 
     The Company has three categories of IT consultants: salaried employees,
associate employees and independent contractors. Salaried employees are
full-time employees of the Company and are eligible for all benefits offered by
the Company. Associate employees are eligible for the same benefits offered to
salaried employees but are paid on an hourly basis and, as such, are not
entitled to paid time off in the form of sick days, personal days or vacation.
Approximately 76% of the Company's IT consultants are salaried employees and 15%
are associate employees. Independent contractors are not employees of the
Company, but are paid on an hourly basis and are not entitled to any benefits
offered to Company employees. Approximately 9% of the Company's IT consultants
are independent contractors.
 
     The Company is not a party to any collective bargaining agreements and
considers its relationships with its employees to be good.
 
RECRUITING AND TRAINING
 
     The Company employs 14 full time recruiters and 3 recruiting managers who
are responsible for recruiting and establishing relationships with qualified
technical personnel. Technical personnel meeting the Company's standards are
added to a computerized database. Recruiting managers maintain regular contact
with technical personnel, monitor their availability and changes in skill levels
and update the database, which has been maintained for over 23 years. See "Risk
Factors -- Need to Attract and Retain Qualified Technical Consultants."
 
     In the first quarter of 1996, the Company implemented an entry-level
training program to address the current shortage of available technical
consultants for its Century Date Compliance engagements. The Company actively
recruits college graduates with degrees other than computer science, such as
music, mathematics and philosophy. Based upon its recent experience with the
training program, the Company believes such individuals have the aptitude to
develop the requisite systems and programming skills. The Company enrolls these
individuals in an intensive six- to eight-week entry-level training course. Upon
completion of training, the Company places these individuals on Century Date
Compliance engagements, where they work under the supervision of experienced
consultants. The Company enters into employment agreements with these
individuals, whereby the consultants agree to reimburse the Company for some or
all of the cost of their training if they leave the Company within four years.
Since the commencement of this entry-level training program on February 15,
1996, 46 individuals have entered and successfully completed training. The
Company is currently conducting an additional entry-level training class for 14
individuals and intends to conduct additional training classes on a regular
basis in 1997. Advanced course modules are under development and will
concentrate on the Company's other service offerings, such as Systems
Re-engineering and IDS.
 
COMPETITION
 
     The market for IT professional services is intensely competitive on local
and national level, and the Company competes frequently with a variety of
companies for both the same clients and qualified technical consultants. These
companies include: "Big Six" accounting firms, systems consulting and
implementation firms, application software firms, service groups of computer
equipment companies, general management consulting firms and programming
companies. The Company considers large organizations with complex IT needs to be
among its primary clients. Within a given market, there are a limited number of
such potential clients, some of which have designated only certain IT
professional services companies as approved providers of IT professional
services. Primary competitive factors for obtaining and retaining clients
include: price, quality of services, technical expertise and responsiveness to
client needs. The primary competitive factors in attracting and retaining
qualified candidates as consultants are competitive compensation arrangements
and consistent exposure to high quality and varied engagements.
 
     Several of the Company's competitors are substantially larger than the
Company and have greater financial and other resources. Many of such competitors
have also been in business longer than the Company
 
                                       28
<PAGE>   30
 
and have significantly greater name recognition throughout the United States,
including the geographic areas in which the Company operates and into which it
may expand. In addition, such companies are able to meet a broader range of a
client's IT consulting needs and serve a broader geographic range than the
Company, which permits such companies to better serve national accounts.
Although the Company believes that it competes, and will continue to compete,
favorably with existing and future competitors, there can be no assurance that
the Company will continue to do so. See "Risk Factors -- Competition" and "Risk
Factors -- Need to Attract and Retain Qualified Technical Consultants."
 
INTELLECTUAL PROPERTY RIGHTS
 
     Software developed by SPR in connection with a client engagement typically
becomes the exclusive property of the client. The Company relies upon a
combination of nondisclosure and other contractual arrangements and trade
secret, copyright and trademark laws to protect its proprietary rights, the
rights of third parties from whom the Company licenses intellectual property and
the proprietary rights of its clients. The Company enters into confidentiality
agreements with its consultants in an effort to prevent the distribution of
proprietary information. See "Risk Factors -- Intellectual Property Rights."
 
     SPR(SM), Renovation(SM), Renovation2000(SM), CodeVu(SM) and the SPR logo
are service marks of the Company. The Company holds no patents or registered
copyrights, and has no present intention of registering any copyright or filing
any patent applications. See "-- Propriety Methodologies."
 
PROPERTY
 
     SPR leases its principal executive offices, which are located at 2015
Spring Road, Oak Brook, Illinois 60521, and also leases facilities in Tulsa,
Oklahoma and Milwaukee, Wisconsin. These leases expire on January 21, 2002,
December 31, 2000 and May 31, 2001, respectively. The Company's principal
executive offices contain a Virtual Insourcing Center. The Company has recently
leased space in Oak Brook, Illinois to house an additional Virtual Insourcing
Center. The Company believes it has adequate space to conduct its current
business. The Company anticipates, however, that additional space will be
required as business expands but believes that it will be able to obtain
suitable space as needed. See Note 5 of Notes to Financial Statements.
 
LEGAL PROCEEDINGS
 
     The Company is not involved in any material legal proceedings.

     Option Grants
 
     There were no options or stock appreciation rights granted and no

Control (as defined in the agreements) and the occurrence of certain events, and
to the extent deductible under then applicable tax laws, the Company shall pay
the executive a payment equal to the sum of (i) the executive's most recent base
annual compensation in effect at the date of the Change in Control, plus (ii)
the cash value of the insurance protection (including dependent coverage) then
in effect with respect to the Company's health insurance plan, based upon the
cost of such insurance to the Company for a 12-month period following the Change
in Control date. Each of these executives is subject to a covenant not to
compete, a nonsolicitation covenant and a nondisclosure covenant.

STOCK PLANS
 
     Employee Stock Purchase Plan. The Company has reserved an aggregate of
500,000 shares of Common Stock for issuance under the Company's Employee Stock
Purchase Plan (the "Purchase Plan"). The Purchase Plan is intended to qualify
under Section 423 of the Internal Revenue Code of 1986, as amended (the "Code"),
and will permit eligible employees of the Company who have completed five full
calendar months of service to purchase Common Stock through payroll deductions
of up to 20% of their total cash compensation; provided that employees may be
prohibited from purchasing more than $20,000 worth of stock in any calendar
year. The Purchase Plan has two six-month offering periods, beginning on January
1 and July 1 of each year, with the first offering period commencing on the date
of this Prospectus. The purchase price of Common Stock purchased under the
Purchase Plan equals 85% of the fair market value of the Common Stock (as
calculated pursuant to the Purchase Plan) on the last day of an offering period.
The Purchase Plan is administered by the Compensation Committee of the Board of
Directors. The Board of Directors is authorized to amend or terminate the
Purchase Plan at any time. However, the Board of Directors may not, without
stockholder approval, modify the Purchase Plan if stockholder approval of the
amendment is required for the Purchase Plan to continue to comply with the
requirements of Rule 16b-3 under the Securities Exchange Act of 1934, as amended
(the "Exchange Act"), or Section 423 of the Code.
 
     Combined Incentive and Non-statutory Stock Option Plan. The Company has
reserved an aggregate of 800,000 shares of Common Stock for issuance under the
Option Plan, which may be granted to employees, officers and directors of the
Company. The Option Plan is administered by the Compensation Committee of the
Board of Directors. The Compensation Committee provides for awards of
Non-statutory Stock Options ("NQSOs") and Incentive Stock Options ("ISOs") to
purchase shares of Common Stock and stock appreciation rights ("SARs"), provided
that any director who is not an employee of the Company may not be awarded an
ISO. The Option Plan limits the aggregate fair market value of the shares of
Common Stock with respect to which ISOs are exercisable for the first time in
any calendar year to $100,000. No such annual limitation applies to NQSO grants
under the Option Plan.
 
     The exercise price for options and SARs may be paid: (i) in cash; (ii) by
surrendering shares already owned by the optionee; or (iii) if the Compensation
Committee so determines by instructing a broker to sell enough of the optionee's
exercised shares to deliver to the Company sufficient sales proceeds to pay the
exercise price. The exercise price per share of Common Stock may not be less
than 85% (100% in the case of an ISO) of the fair market value of the Common
Stock (as calculated pursuant to the Option Plan) on the date the stock option
is granted. The base value of an SAR will equal not less than 85% of the market
value of a share of Common Stock on the grant date. Option agreements covering
options and SARs to be granted under the Option Plan will generally provide that
such options and SARs will be exercisable within fifteen years from the date of
grant (ten years in the case of ISOs) and will generally vest in annual
installments as determined by the Compensation Committee. In the case of any
eligible employee who owns or is deemed to own stock possessing more than 10% of
the total combined voting power of all classes of stock of the Company, the
exercise price of any ISOs granted under the Option Plan may not be less than
110% of the fair market value of the Common Stock on the date of grant and the
exercise period may not exceed five years from the date of grant.
 
     The Board of Directors can terminate or amend the Option Plan at any time,
except that no such action generally will be able to adversely affect any right
or obligation regarding any awards previously made under the Option Plan without
the consent of the recipient. In addition, no amendment may be effective without
the prior approval of stockholders, if such approval is required for the Option
Plan to continue to comply with applicable regulations of the Code and the
Securities and Exchange Commission (the "Commission"). In the event of any
changes in the capital structure of the Company, such as a stock dividend or
stock split, the Board of Directors must make equitable adjustments to
outstanding unexercised awards and to the provisions of the Option Plan to
reflect any increase or decrease in the number of issued shares of Common Stock.
If the Company becomes a party to a merger, reorganization, liquidation or
similar transaction, the Board of Directors may make such arrangements it deems
advisable regarding outstanding awards, such as substituting new awards for
outstanding awards, assuming outstanding awards or terminating or paying for
outstanding awards.
 
     Options to purchase 442,000 shares of Common Stock are expected to be
granted under the Option Plan prior to the consummation of the Offering.

     During 1993, 1994 and 1995, the Company made distributions of $80,955,
$744,559 and $800,663, respectively, to its stockholders to enable them to pay
income taxes attributable to S corporation income of the Company for such
periods.
 
     In 1992 and 1993, Systems Inc. and Data Flex made loans to Eugene Figliulo
in the original principal amounts of $589,770 and $100,000, respectively. Such
loans are evidenced by separate unsecured promissory notes and bear interest at
6% per annum. As of October 31, 1996, the Systems Inc. note was paid in full and
the entire unpaid principal balance plus accrued interest due on the Data Flex
note was outstanding. The Data Flex note plus accrued interest is expected to be
paid with a portion of the proceeds of this Offering payable to Mr. Figliulo.
 
     In 1994, SPR Chicago made an unsecured loan to Robert Figliulo in the
principal amount of $91,000. This loan is evidenced by a promissory note and
bears interest at 7% per annum. As of October 31, 1996, $46,479 plus accrued
interest was outstanding on this note.
 
     During 1994, Systems Inc. transferred certain of its assets and liabilities
in Chicago, Tulsa and Milwaukee to three S corporations organized by the
respective executives primarily responsible for operations in each of those
locations. SPR Chicago, all of whose stock was owned by Robert Figliulo and
David Figliulo, acquired the Chicago operations. SPR Tulsa, all of whose stock
was owned by Michael Fletcher and Rene Potter (neither of whom is related to the
Figliulo family), acquired the Tulsa operations. SPR Wisconsin, all of whose
stock was owned by John Figliulo, acquired the Milwaukee operations. Systems
Inc. retained the trademark "SPR" and licensed it to each of these new
corporations for use in their respective geographic areas. Also in 1994, Systems
Inc. redeemed all of Eugene Figliulo's stock for an installment note in the
principal amount of $2,881,266, bearing interest at a rate of 6.75% per annum (
the "Redemption Note"). As of October 31, 1996, $801,266 was outstanding under
the Redemption Note, all of which is expected to be paid with a portion of the
net proceeds of the Offering received by the Company.
 
     In connection with the transfers of assets and liabilities, SPR Chicago,
SPR Tulsa and SPR Wisconsin delivered to Systems Inc. notes in the principal
amounts of $1,350,133, $1,600,000 and $1,300,000, respectively. Each such note
was payable in monthly installments of principal and interest. In addition, each
corporation agreed to make an additional contingent payment to Systems Inc. in
the event certain "capital events" occurred prior to the one year anniversary
after the final payment is made on its respective note. The loan agreements
restricted borrowings, capital expenditures, amounts of compensation payable to
directors, officers and key employees, sales of assets, mergers, and certain
other business transactions; and the notes were collateralized by the stock of
the respective company and substantially all its assets.
 
     SPR Chicago was reincorporated as a Delaware corporation upon the formation
of SPR and the Merger of SPR Chicago into SPR in October 1996. In the Merger,
Robert Figliulo and David Figliulo each received 1,476,914 shares of Common
Stock. Also in October 1996: (i) SPR Tulsa was merged into SPR and Michael
Fletcher and Rene Potter each received 647,571 shares of Common Stock in the
Merger; (ii) SPR Wisconsin was merged into SPR and John Figliulo received
462,197 shares of Common Stock in the Merger; and (iii) Systems Inc. and Data
Flex were merged into SPR. Each stockholder of Systems Inc. and Data Flex

     The Company intends to enter into a Registration Rights Agreement with
Robert Figliulo, David Figliulo, John Figliulo and Michael Fletcher covering an
aggregate of 532,184 shares of Common Stock. Such Registration Rights Agreement
provides these individuals with demand and piggyback registration rights which
become exercisable one year after the closing of the Offering and continue until
all such shares have been sold. See "Description of Capital
Stock -- Registration Rights."
 
     The Company intends to enter into a tax indemnity agreement with each of
its current stockholders which provides, among other things, that the Company
will indemnify such stockholders against additional income taxes resulting from
adjustments made (as a result of a final determination made by a competent tax
authority) to the taxable income reported by the Company as an S corporation for
periods prior to the Offering, but only to the extent those adjustments result
in a decrease in income taxes otherwise payable by the Company as a C
corporation for periods after the Offering.

                          DESCRIPTION OF CAPITAL STOCK
 
GENERAL
 
     The following brief description of the Company's capital stock does not
purport to be complete and is subject in all respects to applicable Delaware law
and to the provision of the Certificate of Incorporation and By-laws, copies of
which have been filed as exhibits to the Registration Statement on Form S-1 of
which this Prospectus is a part and to which exhibits reference is hereby made.
 
     The authorized capital stock of the Company consists of 13,000,000 shares
of Common Stock, $.01 par value per share, and 3,000,000 shares of Preferred
Stock, $.01 par value per share. Immediately following consummation of the
Offering, there will be 8,000,000 shares of Common Stock outstanding, no shares
of Preferred Stock outstanding and 442,000 shares of Common Stock will be
issuable upon exercise of outstanding options (30,000 of which will be then
exercisable).
 
COMMON STOCK
 
     Holders of Common Stock are entitled to one vote per share on all matters
to be voted upon by stockholders, including the election of directors. There are
no cumulative voting rights for the election of directors.
 
     Holders of Common Stock are entitled to receive such dividends as may be
declared from time to time by the Board of Directors out of funds legally
available therefor after payment of dividends required to be paid on outstanding
Preferred Stock, if any. See "Dividend Policy." Holders of Common Stock are
entitled to share ratably in the net assets of the Company upon liquidation
after payment or provision for all liabilities and any preferential liquidation
rights of any preferred stock then outstanding.
 
     Holders of Common Stock have no preemptive rights to purchase shares of
capital stock of the Company. Shares of Common Stock are not subject to any
redemption provisions and are not convertible into any other securities of the
Company. All outstanding shares of Common Stock are, and the shares of Common
Stock to be issued pursuant to the Offering will be, upon payment therefor, duly
authorized, validly issued, fully paid and non-assessable.
 
     Prior to the Offering, there has been no public market for the Common
Stock. The Company has applied for listing of the Common Stock for quotation on
the Nasdaq National Market under the symbol "SPRI."
 
PREFERRED STOCK
 
     The Board of Directors is authorized without stockholder action to adopt
resolutions to issue up to 3,000,000 shares of Preferred Stock, in one or more
series, with such powers, designations, preferences and relative, participating,
optional or other special rights, qualifications, limitations or restrictions as
will be set forth in such resolutions. The holders of Preferred Stock will have
no preemptive rights (unless otherwise provided in the applicable certificate of
designation). Such Preferred Stock may have voting or other rights which could
adversely affect the rights of holders of the Common Stock. In addition, the
issuance of Preferred Stock, while providing flexibility in connection with
possible acquisitions and other corporate purposes, could, under certain
circumstances, make it more difficult for a third-party to gain control of the
Company, discourage bids for the Common Stock at a premium, or otherwise
adversely affect the market price of the Common Stock. The Company has no
current plans to issue any shares of Preferred Stock.
 
DELAWARE LAW AND CERTAIN CERTIFICATE OF INCORPORATION AND BY-LAW PROVISIONS;
ANTI-TAKEOVER EFFECTS
 
     The Company will be subject to the provisions of Section 203 of the
Delaware General Corporation Law (the "DGCL") upon consummation of this
Offering. Subject to certain exceptions, Section 203 prohibits a publicly held
Delaware corporation from engaging in a "business combination" with an
"interested stockholder" for a period of three years after the date of the
transaction in which the person became an interested stockholder, unless the
interested stockholder attained such status with the approval of the Board of
Directors or the business combination is approved in a prescribed manner, or
certain other conditions are satisfied. A
 
                                       37
<PAGE>   39
 
"business combination" includes mergers, asset sales and other transactions
resulting in a financial benefit to the interested stockholder. Subject to
certain exceptions, an "interested stockholder" is a person who, together with
affiliates and associates, owns, or within three years did own, 15% or more of
the corporation's voting stock.
 
     The Company's By-laws provide that for nominations for the Board of
Directors or for other business to be properly brought by a stockholder before
an annual meeting of stockholders, the stockholder must first have given timely
notice thereof in writing to the Secretary of the Company. To be timely, a
notice must be delivered not less than 60 days nor more than 90 days prior to
the first anniversary of the preceding year's annual meeting. The notice must
contain, among other things, certain information about the stockholder
delivering the notice and, as applicable, background information about each
nominee or a description of the proposed business to be brought before the
meeting. The Company's By-laws provide that any director may be removed only for
cause upon the affirmative vote of at least 66% of the shares entitled to vote
for the election of directors.
 
     The Company's By-laws provide that special meetings of stockholders may be
called only by the Chairman of the Board of Directors or the President of the
Company. These provisions could have the effect of delaying until the next
annual stockholders meeting stockholder actions which are favored by the holders
of a majority of the outstanding voting securities of the Company.
 
     The existence of unissued Preferred Stock enables the Board of Directors to
render more difficult or to discourage an attempt to obtain control of the
Company by means of a tender offer, proxy contest, merger or otherwise, thereby
protecting the continuity of the Company's management. The issuance of Preferred
Stock pursuant to the Board of Directors' authority described above may
adversely affect the rights of the holders of Common Stock. For example,
Preferred Stock issued by the Company may rank prior to the Common Stock as to
dividend rights, liquidation preference or both, may have full or limited voting
rights and may be convertible into shares of Common Stock. Accordingly, the
issuance of Preferred Stock may discourage bids for the Common Stock or may
otherwise adversely affect the market price of the Common Stock.
 
     The foregoing provisions could have the effect of making it more difficult
for a third-party to acquire, or of discouraging a third-party from acquiring
control of the Company.
 
LIMITATION OF LIABILITY AND INDEMNIFICATION
 
     The Company's Certificate of Incorporation contains certain provisions
permitted under the DGCL, relating to the liability of directors. These
provisions eliminate a director's personal liability for monetary damages
resulting from a breach of fiduciary duty, except in certain circumstances
involving certain wrongful acts, such as: (i) for any breach of the director's
duty of loyalty to the Company or its stockholders; (ii) for acts or omissions
not in good faith or which involve intentional misconduct or a knowing violation
of law; (iii) under Section 174 of the DGCL; or (iv) for any transaction from
which the director derives an improper personal benefit. These provisions do not
limit or eliminate the rights of the Company or any stockholder to seek
non-monetary relief, such as an injunction or rescission, in the event of a
breach of a director's fiduciary duty. These provisions will not alter a
director's liability under federal securities laws. The Company's Certificate of
Incorporation and By-laws also contain provisions indemnifying the directors and
officers of the Company to the fullest extent permitted by the DGCL. The Company
believes that these provisions will assist the Company in attracting and
retaining qualified individuals to serve as directors and officers.
 
REGISTRATION RIGHTS
 
     Under the terms of a Registration Rights Agreement to be executed
immediately prior to the consummation of the Offering (the "Registration
Agreement"), Robert Figliulo, David Figliulo, John Figliulo and Michael Fletcher
will be granted certain demand and piggyback registration rights covering an
aggregate of 532,184 shares of Common Stock (the "Registrable Securities"). The
Registration Agreement will provide the holders of the Registrable Securities
with the right to require the Company to register any or all of the Registrable
Securities, subject to the conditions and limitations contained in the
Registration Agreement. Such registration rights become exercisable one year
subsequent to the closing of the Offering and continue
 
                                       38
<PAGE>   40
 
until all shares of Registrable Securities are sold. In addition, if the Company
proposes to register under the Securities Act any of its securities for its own
account, such stockholders may require the Company to include in such
registration all or a part of such Registrable Securities. Pursuant to the
Registration Agreement and the conditions and limitations set forth therein, the
Company is required to: (i) pay all associated Registration Expenses (as defined

                        SHARES ELIGIBLE FOR FUTURE SALE
 
     Upon completion of the Offering, the Company will have 8,000,000 shares of
Common Stock outstanding, assuming no exercise of options expected to be
outstanding and exercisable. The shares sold in the Offering will be freely
tradeable without restriction or limitation under the Securities Act, except for
any such shares acquired by "affiliates" of the Company, as such term is defined
under the Securities Act ("Affiliates"), which shares may generally only be sold
in compliance with the limitations of Rule 144 described below.
 
     The remaining 5,300,000 shares of Common Stock (the "Restricted Shares")
constitute restricted securities under Rule 144 and were issued or sold by the
Company in private transactions and may be publicly sold only if registered
under the Securities Act or sold in accordance with an applicable exemption from
registration, such as Rule 144. The Company and all executive officers,
directors and stockholders of the Company have agreed with the Representatives
not to offer, sell contract to sell or otherwise dispose, or contract to
dispose, of any shares of Common Stock or any securities convertible into or
exercisable or exchangeable for Common Stock, or grant any options or warrants
to purchase Common Stock, except in certain circumstances, for a period of 180
days after the date of this Prospectus (the "Lock-up Period") without the prior
written consent of Smith Barney Inc. Upon the expiration of the Lock-up Period
(or earlier with the consent of Smith Barney Inc.), all of the Restricted Shares
will become eligible for sale subject to the restrictions of Rule 144.
 
     In general, under Rule 144 as currently in effect, a person (or persons
whose shares are aggregated) who has beneficially owned Restricted Shares for at
least two years, including a person who may be deemed an Affiliate of the
Company, is entitled to sell within any three-month period a number of shares of
Common Stock that does not exceed the greater of 1% of the then outstanding
shares of Common Stock (approximately 80,000 shares after giving effect to the
Offering) and the average weekly reported trading volume of the Common Stock as
reported through the Nasdaq National Market during the four calendar weeks
preceding the sale. Sales under Rule 144 are subject to certain restrictions
relating to manner of sale, notice and the availability of current public
information about the Company. In addition, under Rule 144(k), a person who has
not been an Affiliate of the Company at any time 90 days preceding a sale, and
who has beneficially owned shares for at least three years, would be entitled to
sell such shares immediately following the Offering without regard to the volume
limitations, manner of sale provisions or notice or other requirements of Rule
144.
 
     Upon the closing of the Offering, options to purchase a total of 442,000
shares of Common Stock are expected to be outstanding, of which 30,000 are
expected to be then exercisable. An additional 358,000 shares of Common Stock
will be available for future options grants under the Option Plan. An additional
500,000 shares of Common Stock will be available for issuance under the Employee
Stock Purchase Plan. See "Management -- Stock Plans." Rule 701 under the
Securities Act provides that shares of Common Stock acquired on the exercise of
outstanding options may be resold by persons other than Affiliates, beginning 90
days after the date of this Prospectus, subject only to the manner of sale
provisions of Rule 144, and by Affiliates, beginning 90 days after the date of
this Prospectus, subject to all provisions of Rule 144, except its two-year
minimum holding period. The Company intends to register on a registration
statement or statements on Form S-8 the shares of Common Stock to be issued
under the Option Plan and the Purchase Plan.
 
     The Company intends to grant Robert Figliulo, David Figliulo, John Figliulo
and Michael Fletcher demand and piggyback registration rights covering an
aggregate of 532,184 shares of Common Stock. These registration rights will
become exercisable one year subsequent to the closing of the Offering and
continue until all shares of Registrable Securities are sold. To the extent
these rights are exercised, additional shares of Common Stock will become
available for sale upon the effectiveness of a registration statement filed
pursuant to exercise of such rights. See "Description of Capital Stock --
Registration Rights."
 
     Prior to the Offering there has been no public market for the Common Stock
and any sale of substantial amounts of Common Stock in the open market may
adversely affect the market price of the Common Stock offered hereby.

     The Underwriting Agreement provides that the obligations of the several
Underwriters to pay for and accept delivery of the shares are subject to
approval of certain legal matters by counsel and to certain other conditions.
The Underwriters are obligated to take and pay for all shares of Common Stock
offered hereby (other than those covered by the over-allotment option described
below) if any such shares are taken.
 
     The Underwriters initially propose to offer a portion of the shares
directly to the public at the initial public offering price set forth on the
cover page of this Prospectus and a portion of the shares to certain dealers at
a price which represents a concession not in excess of $     per share below the
public offering price. The Underwriters may allow, and such dealers may reallow,
a concession not in excess of $     per Share to certain other dealers. After
the initial public offering of the shares to the public, the public offering
price and such concessions may be changed by the Underwriters. The
Representatives of the Underwriters have advised the Company that the
Underwriters do not intend to confirm the sale of any shares to any accounts
over which they exercise discretionary authority.
 
     Certain of the Selling Stockholders have granted the Underwriters an
option, exercisable for 30 calendar days from the date of this Prospectus, to
purchase up to 405,000 additional shares of Common Stock at the initial offering
price set forth on the cover page of this Prospectus, less the underwriting
discounts and commissions. The Underwriters may exercise such option solely for
the purpose of covering over-allotments, if any, in connection with the
Offering. To the extent such option is exercised, each Underwriter will be
obligated, subject to certain conditions, to purchase approximately the same
percentage of such additional shares as the number of shares set forth opposite
each Underwriter's name above bears to the total number of shares listed above.
 
     The Underwriters have reserved up to 135,000 shares of the Common Stock
offered hereby for sale at the initial public offering price to certain
employees, consultants and other persons associated with the Company. The number
of shares of Common Stock available for sale to the general public will be
reduced to the extent such persons purchase such reserved shares. Any reserved
shares not so purchased will be offered by the Underwriters to the general
public on the same basis as the other shares offered hereby.
 
     The Company and all of its directors, executive officers and stockholders
have agreed not to offer, sell, contract to sell or otherwise dispose, or
contract to dispose, of any shares of Common Stock or any securities convertible
into or exercisable or exchangeable for Common Stock, or grant any options or
warrants to purchase Common Stock, except in certain circumstances, for a period
of 180 days after the date of this Prospectus without the prior written consent
of Smith Barney Inc.
 
     Prior to the Offering, there has been no public market for the Common
Stock. The initial public offering price of the shares will be negotiated among
the Company, the Selling Stockholders and the Representatives. Among the factors
expected to be considered in determining the initial public offering price are
the history of and prospects for the Company's business and the industry in
which it competes, an assessment of the Company's management and the present
state of the Company's development, the Company's past and present revenues and
earnings, the prospects for growth of the Company's revenues and earnings, the
current state of the U.S. economy and the current level of economic activity in
the industry in which the Company
 
                                       41
<PAGE>   43
 
competes and in related or comparable industries, and currently prevailing
conditions in the securities markets, including current valuations of publicly
traded companies which are considered comparable to the Company.
 
     The Company, the Selling Stockholders and the Underwriters have agreed to
indemnify each other against certain liabilities, including liabilities under
the Securities Act of 1933.
 
                                 LEGAL MATTERS
 
     The validity of the issuance of the shares of Common Stock offered hereby
will be passed upon for the Company by Wildman, Harrold, Allen & Dixon, Chicago,
Illinois. Mr. Donald E. Figliulo, a partner of Wildman, Harrold, Allen & Dixon,
is the brother of Robert, David and John Figliulo, the owner of shares of Common
Stock and a Selling Stockholder. Certain legal matters will be passed upon for
the Underwriters by Neal, Gerber & Eisenberg, Chicago, Illinois.
 
                                    EXPERTS
 
     The Financial Statements and Schedule of the Company as of December 31,
1995 and 1994, and for each of the years in the three-year period ended December
31, 1995 included herein and elsewhere in the Registration Statement, have been
audited by Arthur Andersen LLP, independent public accountants, as indicated in
their report thereto, and are included in reliance upon the authority of said
firm as experts in accounting and auditing.
 
                             CHANGE IN ACCOUNTANTS
 
     Prior to September 9, 1996 Arthur Andersen LLP served as independent public
accountants for SPR Wisconsin, SPR Tulsa, Data Flex and Systems Inc. and Ernst &
Young LLP served as independent public accountants for SPR Chicago. In
connection with the Offering, the Board of Directors of the Company on September
9, 1996 dismissed Ernst & Young LLP and selected Arthur Andersen LLP to serve as
independent public accountants for the Company and to render an opinion on the
financial statements included in this Prospectus, including the financial
statements of SPR Chicago. The Company informed Ernst & Young LLP of its
dismissal on September 9, 1996. The former auditors' report on SPR Chicago's
financial statements for the period from January 14, 1994 to December 31, 1994
and for the year ended December 31, 1995 is not included in this Prospectus.
During the period from January 14, 1994 to December 31, 1994 and for the year
ended December 31, 1995, (i) Ernst & Young LLP's report on the financial
statements of SPR Chicago did not contain an adverse opinion, disclaimer of
opinion, qualification or modification as to uncertainty, audit scope or
accounting principles and (ii) there were no disagreements with Ernst & Young
LLP on any matter of accounting principles or practices, financial statement
disclosure, or auditing scope or procedures at the time of change or with
respect to SPR Chicago's financial statements.
 
     The Company has requested Ernst & Young LLP to furnish it a letter
addressed to the Commission stating whether it agrees with the above comments. A
copy of that letter dated November 19, 1996 is filed as an exhibit to the
Registration Statement of which this Prospectus is a part.
 
     The Company consulted Arthur Andersen LLP and did not consult Ernst & Young
LLP regarding the application of the Commission's accounting principles to the
transactions described under "The Company" and the type of audit opinion that
would be rendered on the Company's financial statements included in this
Prospectus, which consultations were the subject of written and oral advice.
 
                             ADDITIONAL INFORMATION
 
     The Company has filed with the Commission a Registration Statement on Form
S-1 under the Securities Act with respect to the Common Stock offered hereby.
This Prospectus, which is part of the Registration Statement, does not contain
all of the information set forth in the Registration Statement, certain parts of
which are omitted in accordance with the rules and regulations of the
Commission. For further information

payment of the prescribed fee. In addition, the Commission maintains a World
Wide Web site on the Internet at www.sec.gov that contains reports, proxy and

containing audited financial statements and an opinion thereon expressed by
independent auditors and may furnish its shareholders with quarterly reports for
the first three quarters of each year containing unaudited summary financial
information.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS
 
To the Stockholders of SPR Inc.:
 
     We have audited the accompanying balance sheets of SPR INC. (a Delaware
corporation) as of December 31, 1994 and 1995, and the related statements of
operations, stockholders' equity and cash flows for each of the three years in
the period ended December 31, 1995. 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 in accordance with generally accepted auditing
standards. Those standards 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. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
     In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of SPR Inc. as of December 31,
1994 and 1995, and the results of its operations and its cash flows for each of
the three years in the period ended December 31, 1995, in conformity with
generally accepted accounting principles.

                         NOTES TO FINANCIAL STATEMENTS
 
NOTE 1 -- BUSINESS AND SIGNIFICANT ACCOUNTING POLICIES
 
     (a) Business -- SPR Inc. (the Company) provides information technology
services to clients in a variety of industry groups including financial
services, healthcare, insurance, manufacturing, oil and gas, transportation and
utilities. The Company currently provides the following service offerings: (i)
general consulting, (ii) systems reengineering, (iii) century date compliance,
(iv) systems maintenance and support and (v) information delivery services.
Within each of these service offerings, the Company provides three levels of
consulting support which are distinguished by the degree of responsibility the
Company assumes: strategic planning, project management and implementation.
 
     (b) Interim Financial Information -- The unaudited balance sheet as of
October 31, 1996, the unaudited statement of stockholders' equity for the ten
months ended October 31, 1996, and the unaudited statements of operations and
cash flows for the ten months ended October 31, 1995 and 1996, include, in the
opinion of management, all adjustments (consisting of normal recurring
adjustments) necessary to present fairly the Company's financial position,
results of operations and cash flows. Operating results for the ten months ended
October 31, 1996, are not necessarily indicative of the results that may be
expected for the year ending December 31, 1996. The information included in
these notes relating to the ten months ended October 31, 1995 and 1996, is
unaudited.
 
     (c) Basis of Presentation -- SPR Inc. was formed on October 29, 1996.
During October, 1996, Systems and Programming Resources, Inc., Systems &
Programming Resources of Tulsa, Inc., SPR-Wisconsin, Inc., SPR Chicago Inc., and
Consulting Acquisition, Inc. (d.b.a. Data Flex) merged into SPR Inc. at which
time the stockholders of such companies received an aggregate of 6,333,134
shares of common stock of SPR Inc. Systems and Programming Resources, Inc.,
SPR-Wisconsin, Inc., SPR Chicago Inc., Consulting Acquisition, Inc. and SPR Inc.
are under common ownership and control and are accounted for at historical cost
as a reorganization of entities under common control (similar to the pooling of
interests method of accounting). The merger of Systems & Programing Resources of
Tulsa, Inc. into SPR Inc. was accounted for using the pooling of interests
method of accounting. All intercompany transactions and balances have been
eliminated. The accompanying financial statements of the Company have been
prepared to give retroactive effect to the merger.
 
     (d) Revenue Recognition -- Revenues are recognized as the related services
are performed.
 
     (e) Property and Equipment -- Property and equipment are stated at cost.
Expenditures for repair and maintenance are charged to expense as incurred.
Depreciation and amortization are computed using the straight-line method. The
estimated useful lives used in computing depreciation and amortization for
financial statement purposes are as follows:

        Computer equipment and software...............   5 years
        Office furniture and equipment................   5 to 7 years
</TABLE>
 
     (f) Distributions -- Distributions are recorded when declared by the Board
of Directors.
 
     (g) Use of Estimates -- The preparation of financial statements in
conformity with generally accepted accounting principles requires management to
make estimates and assumptions that affect the reported amounts of assets and
liabilities and disclosure of contingent assets and liabilities at the date of
the financial statements and the reported amounts of revenues and expenses
during the reporting period. Actual results could differ from those estimates.

                   NOTES TO FINANCIAL STATEMENTS (CONTINUED)
 
     (h) Income Taxes -- The Company elected to be taxed as an S corporation for
Federal and certain state income tax purposes. By this election, income of the
Company is taxable to the stockholders.
 
     Upon completion of the Initial Public Offering (the Offering) and effective
termination of the S corporation election, deferred income tax liabilities and
income tax expense will be recorded for taxable temporary differences existing
at the time of change in tax status. Income for Federal income tax purposes was
recognized on the cash basis of accounting and, upon consummation of the
Offering, the Company will change to the accrual basis of accounting. If the
effective date of the Offering had been October 31, 1996, deferred income tax
liabilities and income tax expenses of approximately $600,000 would have been
recorded. Deferred income taxes will be recorded under the asset and liability
method of accounting for income taxes which requires the recognition of deferred
income taxes based upon the tax consequences of "temporary differences" by
applying enacted statutory tax rates applicable to future years to differences
between the financial statements carrying amounts and the tax basis of existing
assets and liabilities. As of October 31, 1996, deferred income tax liabilities
would have consisted of the following:

</TABLE>
 
     Additional paid-in capital and retained earnings (deficit) will be adjusted
to reflect the capitalization of retained earnings (deficit) to additional
paid-in capital upon the conversion of the Company to a C corporation.
 
     The Company intends to enter into a tax indemnity agreement with each of
its current stockholders which provides, among other things, that the Company
will indemnify such stockholders against additional income taxes resulting from
adjustments made (as a result of a final determination made by a competent tax
authority) to the taxable income reported by the Company as an S corporation for
periods prior to the Offering, but only to the extent those adjustments result
in a decrease in income taxes otherwise payable by the Company as a C
corporation for periods after the Offering.
 
NOTE 2 -- CONCENTRATION OF CREDIT RISK
 
     The Company's financial instruments that are exposed to concentrations of
credit risk consist of accounts receivable.
 
     The Company's customers are predominantly in the Midwest, with the majority
of customers located in Chicago, Tulsa and Milwaukee. One customer in the retail
industry accounted for approximately 17% of revenues in 1993 and one customer in
the insurance industry accounted for approximately 11% of revenues in 1995. For
the ten months ended October 31, 1996, a customer in the insurance industry
accounted for approximately 16% of revenues. The Company reviews a customer's
credit history before extending credit. In addition, the Company routinely
assesses the financial strength of its customers and, as a consequence, believes
that its accounts receivable credit risk is limited. The Company has no off
balance sheet credit risk.

NOTE 10 -- STOCK-BASED COMPENSATION
 
     Systems and Programming Resources, Inc. entered into a series of
transactions with stockholders/ employees from January, 1994 through October,
1996. Certain assets and certain liabilities were transferred to SPR Chicago
Inc. and SPR-Wisconsin, Inc. during 1994 that were subsequently transferred to
SPR Inc. in 1996. Because the transactions were among family members within a
control group, the stockholders of SPR Chicago Inc. and SPR-Wisconsin, Inc. were
effectively granted a variable compensation arrangement that is measured by the
increase in the estimated value of these companies (as determined by management)
since 1994. The final measurement occurred when the relative ownership interests
in SPR Inc. were determined in October, 1996. Compensation expense relating to
this arrangement is recorded in the accompanying statements of operations as
stock-based compensation with the corresponding credit included in additional
paid-in-capital.
 
NOTE 11 -- STOCK PLANS -- SUBSEQUENT EVENT (UNAUDITED)
 
     In November, 1996, the Company adopted an Employee Stock Purchase Plan and
a Combined Incentive and Non-statutory Stock Option Plan. 500,000 shares of
common stock are reserved for issuance under the Employee Stock Purchase Plan
and 800,000 shares of common stock are reserved for issuance under the

                   NOTES TO FINANCIAL STATEMENTS (CONTINUED)
 
Combined Incentive and Non-statutory Stock Option Plan. The Employee Stock
Purchase Plan will permit eligible employees who have completed five full
calendar months of service to purchase common stock through payroll deductions
of up to 20% of their total cash compensation provided that no employee may
purchase more than $20,000 worth of stock in any calendar year. The purchase
price equals 85% of the market value of the common stock on the last day of the
offering period, as defined.
 
     The Combined Incentive and Non-statutory Stock Option Plan provides that
awards may be granted to employees, officers and directors of the Company.
Awards may consist of non-statutory stock options and incentive stock options
(ISOs) to purchase shares of common stock and stock appreciation rights (SARs).
The exercise price per share of common stock is 100% of the fair market value of
the common stock on the date the option is granted. Options and SARs granted
under the option plan must be exercised within fifteen years from the date of
grant (ten years in the case of ISOs). In the case of any eligible employee who
owns stock possessing more than 10% of the voting power of stock, the exercise
price of any ISOs granted may not be less than 110% of the fair market value of
the common stock on the date of grant and the exercise period may not exceed
five years from the date of grant.
 
NOTE 12 -- SUBSEQUENT EVENTS AND PRO FORMA FINANCIAL DATA (UNAUDITED)
 
     The Company will convert to a C corporation in connection with the
completion of the Offering resulting in the recording of approximately $600,000
in deferred income tax liabilities, as discussed in Note 1h. Prior to
consummation of the Offering, the Company intends to declare a dividend (the
"Dividend"). The Company currently estimates (based in part on the Company's
estimate of its 1996 earnings) that the Dividend will equal approximately
$2,500,000. Retained earnings (deficit) of the Company (which includes the
aggregate stock-based compensation expense), after recording the estimated
Dividend and deferred income taxes, will be reclassified to additional paid-in
capital in connection with the termination of the Company's S corporation
election. The unaudited pro forma Balance Sheet gives effect to these items. No
other contemplated transactions in connection with the Offering are included in
the unaudited pro forma Balance Sheet information.

ITEM 14. INDEMNIFICATION OF DIRECTORS AND OFFICERS.
 
     The Registrant, being incorporated under the General Corporation Law of the
State of Delaware (the "DGCL"), is empowered by Section 145 of the DGCL, subject
to the procedures and limitations stated therein, to indemnify any person
against expenses (including attorneys' fees), judgments, fines and amounts paid
in settlement actually and reasonably incurred by him or her in connection with
any threatened, pending or completed action, suit or proceeding to which such
person is made a party or threatened to be made a party by reason of the fact
that he or she is or was a director, officer, employee or agent of the
corporation, or is or was serving at the request of the corporation as a
director, officer, employee or agent of another corporation, partnership, joint
venture, trust or other enterprise. Section 145 provides that indemnification
pursuant to its provisions is not exclusive of other rights of indemnification
to which a person may be entitled under any By-Law, agreement, vote of
stockholders or disinterested directors or otherwise.
 
     The Company's Certificate of Incorporation and By-laws contain provisions
that require the Company to indemnify its Directors and officers to the fullest
extent permitted by Delaware law.
 
     Article Ninth of the Registrant's Certificate of Incorporation eliminates,
to the fullest extent permitted by paragraph (7) of subsection (b) of Section
102 of the DGCL, as the same may be amended or supplemented, or any
corresponding provision of the DGCL, the personal liability of directors. That
paragraph allows corporations incorporated under the DGCL to eliminate the
personal liability of a director to the corporation or its stockholders for
monetary damages for a breach of fiduciary duty as a director. However, that
paragraph does not allow corporations to limit the liability of a director: (i)
for any breach of his or her duty of loyalty to the corporation or its
stockholders, (ii) for acts or omission not in good faith or which involve
intentional misconduct or a knowing violations of law, (iii) for unlawful
payment of a dividend or unlawful stock purchase or redemption or (iv) for any
transaction for which the director derived an improper personal benefit.
 
     The Company is in the process of procuring liability insurance for its
directors and officers.
 
ITEM 15. RECENT SALES OF UNREGISTERED SECURITIES
 
     Set forth below is information as to securities of the Registrant and its
predecessors issued or sold by the Registrant and its predecessors since October
31, 1993 that were not registered under the Securities Act of 1933, as amended
(the "Securities Act"). No underwriters were involved, and there were no
underwriting discounts or commissions.

     in such names as required by the Underwriters to permit prompt delivery to
     each purchaser.
 
          (2) That, insofar as indemnification for liabilities arising under the
     Securities Act of 1933 (the "Act") may be permitted to directors, officers
     and controlling persons of the Registrant pursuant to the foregoing
     provisions, or otherwise, the Registrant has been advised that in the
     opinion of the Securities and Exchange Commission such indemnification is
     against public policy as expressed in the Act and is, therefore,
     unenforceable. In the event that a claim for indemnification against such
     liabilities (other than the payment by the Registrant of expenses incurred
     or paid by a director, officer or controlling person of the Registrant in
     the successful defense of any action, suit or proceeding) is asserted by
     such director, officer or controlling person in connection with the
     securities being registered, the Registrant will, unless in the opinion of
     its counsel the matter had been settled by controlling precedent, submit to
     a court of appropriate jurisdiction the question whether such
     indemnification by it is against public policy as expressed in the Act and
     will be governed by the final adjudication of such issue.
 
          (3) That, for purposes of determining any liability under the Act, the
     information omitted from the form of Prospectus filed as part of this
     Registration Statement in reliance upon Rule 430A and contained in a form
     of Prospectus filed by the Registrant pursuant to Rule 424(b)(1) or (4) of
     497(h) under the Act shall be deemed to be part of this Registration
     Statement as of the time it was declared effective.
 
          (4) That, for the purpose of determining any liability under the Act,
     each post-effective amendment that contains a form of prospectus shall be
     deemed to be a new registration statement relating to the securities
     offered therein, and the offering of such securities at that time shall be
     deemed to be the initial bona fide offering thereof.

       REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS ON SUPPLEMENTAL SCHEDULE
 
To the Stockholders of SPR Inc.:
 
     We have audited in accordance with generally accepted auditing standards,
the financial statements of SPR Inc. included in this registration statement and
have issued our report thereon dated October 28, 1996. Our audits were made for
the purpose of forming an opinion on the basic financial statements taken as a
whole. The schedule listed in the index in Item 16(b) is the responsibility of
the Company's management and is presented for purposes of complying with the
Securities and Exchange Commission's rules and is not part of the basic
financial statements. The schedule has been subjected to the auditing procedures
applied in the audit of the basic financial statements and, in our opinion,
fairly states in all material respects the financial data required to be set
forth therein in relation to the basic financial statements taken as a whole.

SMITH BARNEY INC.
ROBERT W. BAIRD & CO. INCORPORATED
As Representatives of the Several Underwriters
c/o  SMITH BARNEY INC.
     388 Greenwich Street
     New York, New York 10013

Dear Sirs:

         SPR Inc., a Delaware corporation (the "Company"), proposes to issue
and sell an aggregate of 1,666,666 shares of its common stock, $0.01 par value
per share, to the several Underwriters named in Schedule II hereto (the
"Underwriters"), and the persons named in Part A of Schedule I hereto (the
"Selling Stockholders") propose to sell to the several Underwriters an
aggregate of 1,033,334 shares of common stock of the Company.  The Company and
the Selling Stockholders are hereinafter sometimes referred to as the
"Sellers."  The Company's common stock, $0.01 par value, is hereinafter
referred to as the "Common Stock" and the 1,666,666 shares of Common Stock to
be issued and sold to the Underwriters by the Company and the 1,033,334 shares
of Common Stock to be sold to the Underwriters by the Selling Stockholders are
hereinafter referred to as the "Firm Shares."  The Company and the Selling
Stockholders listed in Part B of Schedule I hereto also propose to sell to the
Underwriters, upon the terms and conditions set forth in Section 2 hereof, up
to an additional 405,000 shares (the "Additional Shares") of Common Stock.  The
Firm Shares and the Additional Shares are hereinafter collectively referred to
as the "Shares."  All references to the "Company" refer to SPR Inc., after the
Reorganizations described in Section 7(d) hereof have been effected, or to the
Constituent Corporations, as defined in Section 7(d) hereof, as appropriate.

         The Company and the Selling Stockholders wish to confirm as follows
their respective agreements with you (the "Representatives") and the other
several Underwriters on whose behalf you are acting, in connection with the
several purchases of the Shares by the Underwriters.
<PAGE>   2
         1.   Registration Statement and Prospectus.  The Company has prepared
and filed with the Securities and Exchange Commission (the "Commission") in
accordance with the provisions of the Securities Act of 1933, as amended, and
the rules and regulations of the Commission thereunder (collectively, the
"Act"), a registration statement on Form S-1 under the Act (the "registration
statement"), including a prospectus subject to completion relating to the
Shares.  The term "Registration Statement" as used in this Agreement means the
registration statement (including all financial schedules and exhibits), as
amended at the time it becomes effective, or, if the registration statement
became effective prior to the execution of this Agreement, as supplemented or
amended prior to the execution of this Agreement.  If it is contemplated, at
the time this Agreement is executed, that a post-effective amendment to the
registration statement will be filed and must be declared effective before the
offering of the Shares may commence, the term "Registration Statement" as used
in this Agreement means the registration statement as amended by said
post-effective amendment.  If an abbreviated registration statement is prepared
and filed with the Commission in accordance with Rule 462(b) under the Act (an
"Abbreviated Registration Statement"), the term "Registration Statement" as
used in this Agreement includes the Abbreviated Registration Statement.  The
term "Prospectus" as used in this Agreement means the prospectus in the form
included in the Registration Statement, or, if the prospectus included in the
Registration Statement omits information in reliance on Rule 430A under the Act
and such information is included in a prospectus filed with the Commission
pursuant to Rule 424(b) under the Act, the term "Prospectus" as used in this
Agreement means the prospectus in the form included in the Registration
Statement as supplemented by the addition of the Rule 430A information
contained in the prospectus filed with the Commission pursuant to Rule 424(b).
The term "Prepricing Prospectus" as used in this Agreement means the prospectus
subject to completion in the form included in the registration statement at the
time of the initial filing of the registration statement with the Commission,
and as such prospectus shall have been amended from time to time prior to the
date of the Prospectus.

         2.   Agreements to Sell and Purchase.  Subject to such adjustments as
you may determine in order to avoid fractional shares, the Company hereby
agrees, subject to all the terms and conditions set forth herein, to issue and
sell to each Underwriter and, upon the basis of the representations, warranties
and agreements of the Company and the Selling Stockholders herein contained and
subject to all the terms and conditions set forth herein, each Underwriter
agrees, severally and not jointly, to purchase from the Company, at a purchase
price of $_____ per Share (the "purchase price per share"), the number of Firm
Shares which bears the same proportion to the aggregate number of Firm Shares
to be issued and sold by the Company as the number of Firm Shares set

                                     -2-
<PAGE>   3
forth opposite the name of such Underwriter in Schedule II hereto (or such
number of Firm Shares increased as set forth in Section 12 hereof) bears to the
aggregate number of Firm Shares to be sold by the Company and the Selling
Stockholders.

         Subject to such adjustments as you may determine in order to avoid
fractional shares, each Selling Stockholder agrees, subject to all the terms
and conditions set forth herein, to sell to each Underwriter and, upon the
basis of the representations, warranties and agreements of the Company and the
Selling Stockholders herein contained and subject to all the terms and
conditions set forth herein, each Underwriter, severally and not jointly,
agrees to purchase from each Selling Stockholder at the purchase price per
share that number of Firm Shares which bears the same proportion to the number
of Firm Shares set forth opposite the name of such Selling Stockholder in
Schedule I hereto as the number of Firm Shares set forth opposite the name of
such Underwriter in Schedule II hereto (or such number of Firm Shares increased
as set forth in Section 12 hereof) bears to the aggregate number of Firm Shares
to be sold by the Company and the Selling Stockholders.

         The Company and the Selling Stockholders listed in Part B of Schedule
I hereto also agree, subject to all the terms and conditions set forth herein,
to sell to the Underwriters, and, upon the basis of the representations,
warranties and agreements of the Company and the Selling Stockholders herein
contained and subject to all the terms and conditions set forth herein, the
Underwriters shall have the right to purchase from the Company and the Selling
Stockholders listed in Part B of Schedule I hereto, at the purchase price per
share, pursuant to a one-time option (the "over-allotment option") which may be
exercised at any time prior to 9:00 P.M., New York City time, on the 30th day
after the date of the Prospectus (or, if such 30th day shall be a Saturday or
Sunday or a holiday, on the next business day thereafter when the New York
Stock Exchange is open for trading), up to an aggregate of _______ Additional
Shares from the Company and up to an aggregate of ________ shares from the
Selling Stockholders listed in Part B of Schedule I hereto (the maximum number
of Additional Shares which each of them agrees to sell upon the exercise by the
Underwriters of the over-allotment option is set forth opposite their
respective names in Part B of Schedule I).  Additional Shares may be purchased
only for the purpose of covering over-allotments made in connection with the
offering of the Firm Shares.  The number of Additional Shares which the
Underwriters elect to purchase upon exercise of the over-allotment option shall
be provided by the Company and by each Selling Stockholder who has agreed to
sell Additional Shares in proportion to the respective maximum numbers of
Additional Shares which the Company and each such Selling Stockholder has
agreed to sell.  Upon exercise of the over-allotment option, each Underwriter,
severally and not jointly, agrees to purchase from the Company and





                                     - 3 -
<PAGE>   4
each Selling Stockholder who has agreed to sell Additional Shares the number of
Additional Shares (subject to such adjustments as you may determine in order to
avoid fractional shares) which bears the same proportion to the number of
Additional Shares to be sold by the Company and each Selling Stockholder who
has agreed to sell Additional Shares as the number of Firm Shares set forth
opposite the name of such Underwriter in Schedule II hereto (or such number of
Firm Shares increased as set forth in Section 12 hereof) bears to the aggregate
number of Firm Shares to be sold by the Company and the Selling Stockholders.

         Certificates in transferable form for the Shares (including any
Additional Shares) which each of the Selling Stockholders agrees, severally and
solely with respect to the Shares to be sold by such Selling Stockholder
hereunder, to sell pursuant to this Agreement have been placed in custody with
_______________ (the "Custodian") for delivery under this Agreement pursuant to
a Custody Agreement and Power of Attorney (the "Custody Agreement") executed by
each of the Selling Stockholders appointing ____________ and ____________ as
agents and attorneys-in-fact (the "Attorneys-in-Fact").  Each Selling
Stockholder so agrees that (i) the Shares represented by the certificates held
in custody pursuant to the Custody Agreement are subject to the interests of
the Underwriters, the Company and each other Selling Stockholder, (ii) the
arrangements made by the Selling Stockholders for such custody are, except as
specifically provided in the Custody Agreement, irrevocable, and (iii) the
obligations of the Selling Stockholders hereunder and under the Custody
Agreement shall not be terminated by any act of such Selling Stockholder or by
operation of law, whether by the death or incapacity of any Selling Stockholder
or the occurrence of any other event.  If any Selling Stockholder shall die or
be incapacitated or if any other event shall occur before the delivery of the
Shares hereunder, certificates for the Shares of such Selling Stockholder shall
be delivered to the Underwriters by the Attorneys-in-Fact in accordance with
the terms and conditions of this Agreement and the Custody Agreement as if such
death or incapacity or other event had not occurred, regardless of whether or
not the Attorneys-in-Fact or any Underwriter shall have received notice of such
death, incapacity or other event.  Each Attorney-in-Fact is authorized, on
behalf of each of the Selling Stockholders, to execute this Agreement and any
other documents necessary or desirable in connection with the sale of the
Shares to be sold hereunder by such Selling Stockholder, to make delivery of
the certificates for such Shares, to receive the proceeds of the sale of such
Shares, to give receipts for such proceeds, to pay therefrom any expenses to be
borne by such Selling Stockholder in connection with the sale and public
offering of such Shares, to distribute the balance thereof to such Selling
Stockholder, and to take such other action as may be necessary or desirable in
connection with the transactions contemplated by this





                                     - 4 -
<PAGE>   5
Agreement.  Each Attorney-in-Fact agrees to perform his duties under the
Custody Agreement.

         3.   Terms of Public Offering.  The Sellers have been advised by you
that the Underwriters propose to make a public offering of their respective
portions of the Shares as soon after the Registration Statement and this
Agreement have become effective as in your judgment is advisable and initially
to offer the Shares upon the terms set forth in the Prospectus.

         4.   Delivery of the Shares and Payment Therefor.  Delivery to the
Underwriters of and payment for the Firm Shares shall be made at the offices of
Wildman, Harrold, Allen & Dixon, 225 West Wacker Drive, Suite 3000, Chicago, IL
60606-1229, at 9:00 A.M., Chicago time, on January ___, 1996 (the "Closing

         Delivery to the Underwriters of and payment for any Additional Shares
to be purchased by the Underwriters shall be made at the aforementioned office
of Wildman, Harrold, Allen & Dixon at such time on such date (the "Option
Closing Date"), which may be the same as the Closing Date but shall in no event
be earlier than the Closing Date nor earlier than two nor later than ten
business days after the giving of the notice hereinafter referred to, as shall
be specified in a written notice from you on behalf of the Underwriters to the
Company and the Attorneys-in-Fact of the Underwriters' determination to
purchase a number, specified in such notice, of Additional Shares.  The place
of closing for any Additional Shares and the Option Closing Date for such
Shares may be varied by agreement among you, the Company and the
Attorneys-in-Fact.

         Certificates for the Firm Shares and for any Additional Shares to be
purchased hereunder shall be registered in such names and in such denominations
as you shall request prior to 9:30 A.M., New York City time, on the second
business day preceding the Closing Date or any Option Closing Date, as the case
may be.  Such certificates shall be made available to you in New York City for
inspection and packaging not later than 9:30 A.M., New York City time, on the
business day next preceding the Closing Date or the Option Closing Date, as the
case may be.  The certificates evidencing the Firm Shares and any Additional
Shares to be purchased hereunder shall be delivered to you in New York City on
the Closing Date or the Option Closing Date, as the case may be, against
payment of the purchase price therefor in immediately available funds.

         5.   Agreements of the Company.  The Company agrees with the several
Underwriters as follows:





                                     - 5 -
<PAGE>   6
              (a)   If, at the time this Agreement is executed and delivered,
it is necessary for the Registration Statement, a post-effective amendment
thereto or any Abbreviated Registration Statement to be declared effective
before the offering of the Shares may commence, the Company will endeavor to
cause the Registration Statement, or such post-effective amendment or
Abbreviated Registration Statement, to become effective as soon as possible and
will advise you promptly and, if requested by you, will confirm such advice in
writing, when the Registration Statement, or such post-effective amendment or
Abbreviated Registration Statement has become effective.

              (b)   The Company will advise you promptly and, if requested by
you, will confirm such advice in writing: (i) of any request by the Commission
for amendment of or a supplement to the Registration Statement, any Prepricing
Prospectus or the Prospectus or for additional information; (ii) of the
issuance by the Commission of any stop order suspending the effectiveness of
the Registration Statement or of the suspension of qualification of the Shares
for offering or sale in any jurisdiction or the initiation of any proceeding
for such purpose; and (iii) within the period of time referred to in paragraph
(f) below, of any change, or any development involving a prospective change, in
the Company's condition (financial or other), business, properties, net worth
or results of operations, or of the happening of any event, which makes any
statement of a material fact made in the Registration Statement or the
Prospectus (as then amended or supplemented) untrue or which requires the
making of any additions to or changes in the Registration Statement or the
Prospectus (as then amended or supplemented) in order to state a material fact
required by the Act or the regulations thereunder to be stated therein or
necessary in order to make the statements therein not misleading, or of the
necessity to amend or supplement the Prospectus (as then amended or
supplemented) to comply with the Act or any other law.  If at any time the
Commission shall issue any stop order suspending the effectiveness of the
Registration Statement, the Company will make every reasonable effort to obtain
the withdrawal of such order at the earliest possible time.

              (c)   The Company will furnish to you, without charge, six signed
copies of the registration statement as originally filed with the Commission
and of each amendment thereto, including financial statements and all exhibits
thereto, and will also furnish to you, without charge, such number of conformed
copies of the registration statement as originally filed and of each amendment
thereto, but without exhibits, as you may request.

              (d)   The Company will not (i) file any amendment to the
Registration Statement or make any amendment or supplement to the Prospectus of
which you shall not previously have been advised or to





                                     - 6 -
<PAGE>   7
which you shall reasonably object after being so advised or (ii) so long as, in
the opinion of counsel for the Underwriters, a Prospectus is required to be
delivered in connection with sales by any Underwriter or dealer, file any
information, documents or reports pursuant to the Securities Exchange Act of
1934, as amended (the "Exchange Act") without delivering a copy of such
information, documents or reports to you, as Representatives of the
Underwriters, prior to or concurrently with such filing.

              (e)   Prior to the execution and delivery of this Agreement, the
Company has delivered to you, without charge, in such quantities as you have
requested, copies of each form of the Prepricing Prospectus.  The Company
consents to the use, in accordance with the provisions of the Act and with the
securities or Blue Sky laws of the jurisdictions in which the Shares are
offered by the several Underwriters and by dealers, prior to the date of the
Prospectus, of each Prepricing Prospectus so furnished by the Company.

              (f)   As soon after the execution and delivery of this Agreement
as possible and thereafter from time to time for such period as in the opinion
of counsel for the Underwriters a prospectus is required by the Act to be
delivered in connection with sales by any Underwriter or dealer, the Company
will expeditiously deliver to each Underwriter and each dealer, without charge,
as many copies of the Prospectus (and of any amendment or supplement thereto)
as you may request; provided, however, that in the event any Underwriter is
required to deliver a Prospectus in connection with sales of any of the Shares
at any time nine months or more after the date of the Prospectus, the Company
will expeditiously deliver to such Underwriter, upon request of such
Underwriter but at such Underwriter's expense, as many copies of the Prospectus
(and of any amendment or supplement thereto) as such Underwriter may request.
The Company consents to the use of the Prospectus (and of any amendment or
supplement thereto) in accordance with the provisions of the Act and with the
securities or Blue Sky laws of the jurisdictions in which the Shares are
offered by the several Underwriters and by all dealers to whom Shares may be
sold, both in connection with the offering and sale of the Shares and for such
period of time thereafter as the Prospectus is required by the Act to be
delivered in connection with sales by any Underwriter or dealer.  If during
such period of time any event shall occur that, in the opinion of counsel for
the Underwriters and counsel for the Company, is required to be set forth in
the Prospectus (as then amended or supplemented) or should be set forth therein
in order to make the statements therein, in the light of the circumstances
under which they were made, not misleading, or if it is necessary to supplement
or amend the Prospectus to comply with the Act or any other law, the Company
will forthwith prepare and, subject to the provisions of paragraph (d) above,
file with the Commission an





                                     - 7 -
<PAGE>   8
appropriate supplement or amendment thereto, and will expeditiously furnish to
the Underwriters and dealers a reasonable number of copies thereof, subject to
the proviso to the first sentence of this Section 5(f).  In the event that the
Company and you, as Representatives of the several Underwriters, agree that the
Prospectus should be amended or supplemented, the Company, if requested by you,
will promptly issue a press release announcing or disclosing the matters to be
covered by the proposed amendment or supplement.

              (g)   The Company will cooperate with you and with counsel for
the Underwriters in connection with the registration or qualification of the
Shares for offering and sale by the several Underwriters and by dealers under
the securities or Blue Sky laws of such jurisdictions as you may designate and
will file such consents to service of process or other documents necessary or
appropriate in order to effect such registration or qualification; provided
that in no event shall the Company be obligated to qualify to do business in
any jurisdiction where it is not now so qualified or to take any action which
would subject it to service of process in suits, other than those arising out
of the offering or sale of the Shares, in any jurisdiction where it is not now
so subject.

              (h)   The Company will make generally available to its security
holders a consolidated earnings statement, which need not be audited, covering
a twelve-month period commencing after the effective date of the Registration
Statement and ending not later than 15 months thereafter, as soon as
practicable after the end of such period, which consolidated earnings statement
shall satisfy the provisions of Section ll(a) of the Act.

              (i)   During the period of five years hereafter, the Company will
furnish to you (i) as soon as available, a copy of each report of the Company
mailed to stockholders or filed with the Commission, and (ii) from time to time
such other information concerning the Company as you may request.

              (j)   If this Agreement shall terminate or shall be terminated
after execution pursuant to any provisions hereof (otherwise than pursuant to
the second paragraph of Section 12 hereof or by notice given by you terminating
this Agreement pursuant to Section 12 or Section 13 hereof), or if this
Agreement shall be terminated by the Underwriters because of any failure or
refusal on the part of the Company or the Selling Stockholders to comply with
the terms or fulfill any of the conditions of this Agreement, the Company
agrees to reimburse the Representatives for all reasonable out-of-pocket
expenses (including fees and expenses of counsel for the Underwriters) incurred
by you in connection herewith.  In no event following termination of this
Agreement for any reason will





                                     - 8 -

the Underwriters seek to recover lost profits from the Sellers, or any of them.

              (k)   The Company will apply the net proceeds from the sale of
the Shares to be sold by it hereunder substantially in accordance with the
description set forth in the Prospectus.

              (l)   If Rule 430A of the Act is employed, the Company will
timely file the Prospectus pursuant to Rule 424(b) under the Act and will
advise you of the time and manner of such filing.

              (m)   Except as provided in this Agreement, the Company will not,
sell, contract to sell or otherwise dispose of any Common Stock or any
securities convertible into or exercisable or exchangeable for Common Stock, or
grant any options, warrants or any other instrument convertible, exchangeable
or granting any right to purchase Common Stock, for a period of 180 days after
the date of the Prospectus, without the prior written consent of Smith Barney
Inc.; provided, however, that the Company may grant options under its Combined
Incentive and Non-Statutory Stock Option Plan (and may issue shares of Common
Stock, in accordance with the terms of such Plan and applicable option
agreements executed in connection therewith, upon exercise of any such options)
and sell shares of Common Stock under the Employee Stock Purchase Plan, in each
case as described in the Prospectus.

              (n)   The Company has furnished or will furnish to you "lock-up"
letters as described in Section 6(d) hereof, in the form previously delivered
by you (the "Lock-Up Letter"), signed by each of its current officers and
directors and each of its current stockholders.

              (o)   Except as stated in this Agreement and in the Prepricing
Prospectus and Prospectus, the Company has not taken, nor will it take,
directly or indirectly, any action designed to or that might reasonably be
expected to cause or result in stabilization or manipulation of the price of
the Common Stock to facilitate the sale or resale of the Shares.

              (p)   The Company will use its best efforts to have the Common
Stock listed, subject to notice of issuance, on the Nasdaq National Market
concurrently with the effectiveness of the registration statement.

         6.   Agreements of the Selling Stockholders.  Each of the Selling
Stockholders agrees, severally and solely with respect to such Selling
Stockholder and the Shares to be sold by such Selling Stockholder, with the
several Underwriters as follows:

              (a)   Such Selling Stockholder will cooperate to the extent
necessary to cause the Registration Statement or any post-effective amendment
thereto or any Abbreviated Registration Statement to become effective at the
earliest possible time.

              (b)   Such Selling Stockholder will pay all Federal and other
taxes, if any on the transfer or sale of the Shares being sold by the Selling
Stockholder to the Underwriters.

              (c)   Such Selling Stockholder will do or perform all things
required to be done or performed by the Selling Stockholder prior to the
Closing Date or any Option Closing Date, as the case may be, to satisfy all
conditions precedent to the delivery of the Shares pursuant to this Agreement.

              (d)   Such Selling Stockholder has executed or will execute a
Lock-Up Letter agreeing not to sell, contract to sell or otherwise dispose of
any Common Stock, except for the sale of Shares to the Underwriters pursuant to
this Agreement, prior to the expiration of 180 days after the date of the
Prospectus, without the prior written consent of Smith Barney Inc.; provided,
however, that any sale or other disposition to a member of such Selling
Stockholder's immediate family, or to a trust for the benefit of a member of
such Selling Stockholder's immediate family, may be effected without the prior
written consent of Smith Barney Inc. so long as such Selling Stockholder
delivers to Smith Barney Inc., no later than three days prior to any such sale
or other disposition (i) written notice describing the terms of such sale or
disposition and (ii) the written agreement of the transferee to be bound by the
terms of the Lock-Up Letter executed by such Selling Stockholder.  A Selling
Stockholder's "immediate family" consists of his or her spouse, parents,
children (including adoptive), grandchildren, siblings, mothers and
fathers-in-law, sons- and daughters-in-law and brothers- and sisters-in-law.

              (e)   Except as stated in this Agreement and in the Prepricing
Prospectus and the Prospectus, such Selling Stockholder will not take, directly
or indirectly, any action designed to or that might reasonably be expected to
cause or result in stabilization or manipulation of the price of the Common
Stock to facilitate the sale or resale of the Shares.

              (f)   Such Selling Stockholder will advise you promptly, and if
requested by you, will confirm such advice in writing, within the period of
time referred to in Section 5(f) hereof, of (i) any





                                     - 10 -

change, or any development involving a prospective change, in the Company's
condition (financial or other), business, properties, net worth or results of
operations, or in information contained in the Prospectus, or any amendment or
supplement thereto, relating to the Company, which comes to the attention of
such Selling Stockholder, or (ii) any new information relating to the Company,
or relating to any matter stated in the Prospectus or any amendment or
supplement thereto, which comes to the attention of such Selling Stockholder,
or (iii) any change in information contained in the Prospectus, or any
amendment or supplement thereto, under the heading "Principal and Selling
Stockholders" relating to such Selling Stockholder, any of which suggests that
any statement made in the Registration Statement or the Prospectus (as then
amended or supplemented, if amended or supplemented) is or may be untrue in any
material respect or that the Registration Statement or Prospectus (as then
amended or supplemented, if amended or supplemented) omits or may omit to state
a material fact or a fact necessary to be stated therein in order to make the
statements therein not misleading in any material respect, or of the necessity
to amend or supplement the Prospectus (as then amended or supplemented, if
amended or supplemented) in order to comply with the Act or any other law.

         7.   Representations and Warranties of the Company.  The Company
represents and warrants to each Underwriter that:

              (a)   Each Prepricing Prospectus included as part of the
registration statement as originally filed or as part of any amendment or
supplement thereto, or filed pursuant to Rule 424 under the Act, complied when
so filed in all material respects with the provisions of the Act, except that
this representation and warranty does not apply to statements in or omissions
from the Prepricing Prospectus made in reliance upon and in conformity with
information relating to any Underwriter furnished to the Company in writing by
or on behalf of any Underwriter through you expressly for use therein.  The
Commission has not issued any order preventing or suspending the use of any
Prepricing Prospectus.


              (b)   The Registration Statement in the form in which it became
or becomes effective and also in such form as it may be when any post-effective
amendment thereto or any Abbreviated Registration Statement shall become
effective and the prospectus and any supplement or amendment thereto when filed
with the Commission under Rule 424(b) under the Act, complied or will comply in
all material respects with the provisions of the Act and did not or will not at
any such times contain an untrue statement of a material fact or omit to state
a material fact required to be stated therein or necessary to make the
statements therein not misleading, except that this representation and warranty
does not apply to statements in or omissions from the registration statement or
the prospectus made in reliance upon and in conformity with information
relating to any

necessary consents, approvals, assignments and other authorizations of (A)
governmental authorities and creditors and (B) material lessors, clients,
vendors and other third parties doing business with any of the parties to the

contemplated by the Merger Agreements (the "Reorganizations"), and for the
Company to assume and continue the businesses of each of SPR Chicago, Inc.,
SPR-Wisconsin, Inc., SPR Tulsa, Inc., Systems and Programming Resources, Inc.

and any Option Closing Date will have, valid and marketable title to the Shares
to be sold by such Selling Stockholder, free and clear of any lien, claim,
community property right, voting trust agreement, security interest or other
encumbrance, including, without limitation, any restriction on transfer.

              (b)   Such Selling Stockholder now has, and on the Closing Date
and any Option Closing Date will have, full legal right, power and
authorization, and any approval required by law, to sell, assign transfer and
deliver such Shares in the manner provided in this Agreement, and upon delivery
of and payment for such Shares hereunder, the several Underwriters will acquire
valid and marketable title to such Shares free and clear of any lien, claim,
community property right, voting trust agreement, security interest, or other
encumbrance.

              (c)   This Agreement and the Custody Agreement have been duly
authorized, executed and delivered by or on behalf of such Selling Stockholder
and are the valid and binding agreements of such Selling Stockholder
enforceable against such Selling Stockholder in accordance with their terms,
except to the extent that enforceability may be limited by applicable
bankruptcy, insolvency or other similar laws relating to or affecting
creditors' rights and remedies generally and except to the extent that rights
to indemnity and contribution under this Agreement may be limited by federal or
state securities laws.

              (d)   Neither the execution and delivery of this Agreement or the
Custody Agreement by or on behalf of such Selling Stockholder nor the
consummation of the transactions herein or therein contemplated by or on behalf
of such Selling Stockholder (i) requires any consent, approval, authorization
or order of, or filing or registration with, any court, regulatory body,
administrative agency or other governmental body, agency or official (except
such as may be required under the Act or such as may be required under state
securities or Blue Sky laws governing the purchase and distribution of the
Shares) or (ii) conflicts or will conflict with or constitutes or will
constitute a breach of, or default under, or violates or will violate (A) any
agreement, indenture or other instrument to which such Selling Stockholder is a
party, by which such Selling Stockholder is or may be bound or to which any of
such Selling Stockholder's property or assets is subject, or (B) any statute,
law, rule, regulation, ruling, judgment, injunction, order or decree applicable
to such Selling Stockholder or to any property or assets of such Selling
Stockholder, except any such statutes, laws, rules, regulations, rulings,
judgments, injunctions, orders or decrees the violation of which, individually
or in the aggregate, could not (1) have a material adverse effect on such
Selling Stockholder's ability to consummate the transactions contemplated in
this Agreement or in the Custody Agreement or (2) result in the breach by such
Selling Stockholder of any representation or warranty contained herein or
therein.

              (e)   The Registration Statement and the Prospectus, insofar as
they relate to such Selling Stockholder, do not and will not contain an untrue
statement of a material fact or omit to state any material fact required to be
stated therein or necessary to make the statements therein not misleading.

              (f)   Although such Selling Stockholder has not undertaken (and
has no duty to undertake) to determine independently, and does not assume any
responsibility for information contained in the Registration Statement or the
Prospectus (except for information contained therein under the heading
"Principal and Selling Stockholders" relating to such Selling Stockholder),
nothing has





                                     - 18 -
<PAGE>   19
come to the attention of such Selling Stockholder that has caused such Selling
Stockholder to believe, and such Selling Stockholder does not have any
knowledge or any reason to believe, that the Registration Statement or the
Prospectus (or any amendment or supplement thereto) contains any untrue
statement of a material fact or omits to state any material fact required to be
stated therein or necessary to make the statements therein not misleading.

              (g)   The representations and warranties of such Selling
Stockholder in the Custody Agreement are, and on the Closing Date and any
Option Closing Date will be, true and correct in all material respects.

              (h)    Such Selling Stockholder has not taken, directly or
indirectly, any action designed to or that might reasonably be expected to
cause or result in stabilization or manipulation of the price of the Common
Stock to facilitate the sale or resale of the Shares, except for the lock-up
arrangements described in the Prospectus.

         9.   Indemnification and Contribution.

              (a) The Company and each Selling Stockholder, jointly and
severally, agree to indemnify and hold harmless each of you and each other
Underwriter and each person, if any, who controls any Underwriter within the
meaning of Section 15 of the Act or Section 20(a) of the Exchange Act from and
against any and all losses, claims, damages, liabilities and expenses
(including reasonable costs of investigation and reasonable fees and
disbursements of counsel) arising out of or based upon any untrue statement or
alleged untrue statement of a material fact contained in any Prepricing
Prospectus or in the Registration Statement or the Prospectus, or in any
amendment or supplement thereto, or any omission or alleged omission to state
therein a material fact required to be stated therein or necessary to make the
statements therein not misleading, except insofar as such losses, claims,
damages, liabilities or expenses arise out of or are based upon any untrue
statement or omission or alleged untrue statement or omission which has been
made therein or omitted therefrom in reliance upon and in conformity with the
information relating to such Underwriter furnished in writing to the Company by
or on behalf of any Underwriter through you expressly for use in connection
therewith; provided, however, that the indemnification contained in this
paragraph (a) with respect to any Prepricing Prospectus shall not inure to the
benefit of any Underwriter (or to the benefit of any person controlling such
Underwriter) on account of any such loss, claim, damage, liability or expense
arising from the sale of the Shares by such Underwriter to any person if a copy
of the Prospectus shall not have been delivered or sent to such person within
the time required by the Act and the regulations thereunder, and the untrue





                                     - 19 -
<PAGE>   20
statement or alleged untrue statement or omission or alleged omission of a
material fact contained in such Prepricing Prospectus was corrected in the
Prospectus, provided that the Company has delivered the Prospectus to the
several Underwriters in requisite quantity on a timely basis to permit such
delivery or sending.  The foregoing indemnity agreement shall be in addition to
any liability which the Company or any Selling Stockholder may otherwise have.

         (b)   If any action, suit or proceeding shall be brought against
any Underwriter or any person controlling any Underwriter in respect of which
indemnity may be sought against the Company or any Selling Stockholder, such
Underwriter or such controlling person shall promptly notify the parties
against whom indemnification is being sought (the "indemnifying parties"), and
such indemnifying parties shall assume the defense thereof, including the
employment of counsel and payment of all fees and expenses.  Such Underwriter
or any such controlling person shall have the right to employ separate counsel
in any such action, suit or proceeding and to participate in the defense
thereof, but the fees and expenses of such counsel shall be at the expense of
such Underwriter or such controlling person unless (i) the indemnifying parties
have agreed in writing to pay such fees and expenses, (ii) the indemnifying
parties have failed to assume the defense and employ counsel, or (iii) the
named parties to any such action, suit or proceeding (including any impleaded
parties) include both such Underwriter or such controlling person and the
indemnifying parties and such Underwriter or such controlling person shall have
been advised in writing by its counsel that representation of such indemnified
party and any indemnifying party by the same counsel would be inappropriate
under applicable standards of professional conduct (whether or not such
representation by the same counsel has been proposed) due to actual or
potential differing interests between them (in which case the indemnifying
party shall not have the right to assume the defense of such action, suit or
proceeding on behalf of such Underwriter or such controlling person).  It is
understood, however, that the indemnifying parties shall, in connection with
any one such action, suit or proceeding, or separate but substantially similar
or related actions, suits or proceedings in the same jurisdiction arising out
of the same general allegations or circumstances, be liable for the reasonable
fees and expenses of only one separate firm of attorneys (in addition to any
local counsel) at any time for all such Underwriters and controlling persons,
which firm shall be designated in writing by Smith Barney Inc., and that all
such reasonable fees and expenses shall be reimbursed as they are incurred.
The indemnifying parties shall not be liable for any settlement of any such
action, suit or proceeding effected without their written consent, but if
settled with such written consent, or if there be a final judgment for the
plaintiff in any such action, suit or proceeding, the indemnifying parties
agree to indemnify and hold harmless any Underwriter, to the extent





                                     - 20 -
<PAGE>   21
provided in the preceding paragraph, and any such controlling person from and
against any loss, claim, damage, liability or expense by reason of such
settlement or judgment.

         (c)  The aggregate liability of each Selling Stockholder under this
Agreement, including with respect to the indemnification and contribution
provisions contained in Section 9, shall be limited to the aggregate proceeds
received by such Selling Stockholder from the Underwriters for the sale of the
Shares sold by such Selling Stockholder hereunder.

         (d)  Each Underwriter agrees, severally and not jointly, to indemnify
and hold harmless the Company, its directors, its officers who sign the
Registration Statement, each Selling Stockholder, and any person who controls
the Company or any Selling Stockholder within the meaning of Section 15 of the
Act or Section 20(a) of the Exchange Act, to the same extent as the foregoing
indemnity from the Company and the Selling Stockholders to each Underwriter,
but only with respect to information relating to such Underwriter furnished in
writing by or on behalf of such Underwriter through you expressly for use in
the Registration Statement, the Prospectus or any Prepricing Prospectus, or any
amendment or supplement thereto.  If any action, suit or proceeding shall be
brought against the Company, any of its directors, any such officer, any
Selling Stockholder, or any such controlling person based on the Registration
Statement, the Prospectus or any Prepricing Prospectus, or any amendment or
supplement thereto, and in respect of which indemnity may be sought against any
Underwriter pursuant to this paragraph (d), such Underwriter shall have the
rights and duties given to the Company by paragraph (b) above (except that if
the Company shall have assumed the defense thereof such Underwriter shall not
be required to do so, but may employ separate counsel therein and participate
in the defense thereof, but the fees and expenses of such counsel shall be at
such Underwriter's expense), and the Company, its directors, any such officer,
the Selling Stockholder, and any such controlling person shall have the rights
and duties given to the Underwriters by paragraph (b) above.  The foregoing
indemnity agreement shall be in addition to any liability which any Underwriter
may otherwise have.

         (e)  If the indemnification provided for in this Section 9 is
unavailable to an indemnified party under paragraphs (a) or (d) hereof in
respect of any losses, claims, damages, liabilities or expenses referred to
therein, then an indemnifying party, in lieu of indemnifying such indemnified
party, shall contribute to the amount paid or payable by such indemnified party
as a result of such losses, claims, damages, liabilities or expenses (i) in
such proportion as is appropriate to reflect the relative benefits received by
the Company and the Selling Stockholders on the one hand and the Underwriters
on the other hand from the offering of the Shares, or (ii) if the allocation
provided by clause (i) above is





                                     - 21 -
<PAGE>   22
not permitted by applicable law, in such proportion as is appropriate to
reflect not only the relative benefits referred to in clause (i) above but also
the relative fault of the Company and the Selling Stockholders on the one hand
and the Underwriters on the other in connection with the statements or
omissions that resulted in such losses, claims, damages, liabilities or
expenses, as well as any other relevant equitable considerations.  The relative
benefits received by the Company and the Selling Stockholders on the one hand
and the Underwriters on the other shall be deemed to be in the same proportion
as the total net proceeds from the offering (before deducting expenses)
received by the Company and the Selling Stockholders bear to the total
underwriting discounts and commissions received by the Underwriters, in each
case as set forth in the table on the cover page of the Prospectus; provided
that, in the event that the Underwriters shall have purchased any Additional
Shares hereunder, any determination of the relative benefits received by the
Company, the Selling Stockholders or the Underwriters from the offering of the
Shares shall include the net proceeds (before deducting expenses) received by
the Company and the Selling Stockholders, and the underwriting discounts and
commissions received by the Underwriters, from the sale of such Additional
Shares, in each case computed on the basis of the respective amounts set forth
in the notes to the table on the cover page of the Prospectus.  The relative
fault of the Company and the Selling Stockholders on the one hand and the
Underwriters on the other hand shall be determined by reference to, among other
things, whether the untrue or alleged untrue statement of a material fact or
the omission or alleged omission to state a material fact relates to
information supplied by the Company or the Selling Stockholders on the one hand
or by the Underwriters on the other hand and the parties' relative intent,
knowledge, access to information and opportunity to correct or prevent such
statement or omission.

         (f)  The Company, the Selling Stockholders and the Underwriters agree
that it would not be just and equitable if contribution pursuant to this
Section 9 were determined by a pro rata allocation (even if the Underwriters
were treated as one entity for such purpose) or by any other method of
allocation that does not take account of the equitable considerations referred
to in paragraph (e) above.  The amount paid or payable by an indemnified party
as a result of the losses, claims, damages, liabilities and expenses referred
to in paragraph (e) above shall be deemed to include, subject to the
limitations set forth above, any legal or other expenses reasonably incurred by
such indemnified party in connection with investigating any claim or defending
any such action, suit or proceeding.  Notwithstanding the provisions of this
Section 9, no Underwriter shall be required to contribute any amount in excess
of the amount by which the total price of the Shares underwritten by it and
distributed to the public exceeds the amount of any damages which such
Underwriter has otherwise been required to





                                     - 22 -
<PAGE>   23
pay by reason of such untrue or alleged untrue statement or omission or alleged
omission.  No person guilty of fraudulent misrepresentation (within the meaning
of Section 11(f) of the Act) shall be entitled to contribution from any person
who was not guilty of such fraudulent misrepresentation.  The Underwriters'
obligations to contribute pursuant to this Section 9 are several in proportion
to the respective numbers of Firm Shares set forth opposite their names in
Schedule II hereto (or such numbers of Firm Shares increased as set forth in
Section 12 hereof) and not joint.

         (g)  No indemnifying party shall, without the prior written consent of
the indemnified party, effect any settlement of any pending or threatened
action, suit or proceeding in respect of which any indemnified party is or
could have been a party and indemnity could have been sought hereunder by such
indemnified party, unless such settlement includes an unconditional release of
such indemnified party from all liability on claims that are the subject matter
of such action, suit or proceeding.

         (h)  Any losses, claims, damages, liabilities or expenses for which an
indemnified party is entitled to indemnification or contribution under this
Section 9 shall be paid by the indemnifying party to the indemnified party as
such losses, claims, damages, liabilities or expenses are incurred.  The
indemnity and contribution agreements contained in this Section 9 and the
representations and warranties of the Company and the Selling Stockholders set
forth in this Agreement shall remain operative and in full force and effect,
regardless of (i) any investigation made by or on behalf of any Underwriter or
any person controlling any Underwriter, the Company, its directors or officers
or the Selling Stockholders or any person controlling the Company, (ii)
acceptance of any Shares and payment therefor hereunder, and (iii) any
termination of this Agreement.  A successor to any Underwriter or any person
controlling any Underwriter, or to the Company, its directors or officers, or
any person controlling the Company, shall be entitled to the benefits of the
indemnity, contribution and reimbursement agreements contained in this Section
9.

         10. Conditions of Underwriters' Obligations.  The several obligations
of the Underwriters to purchase the Firm Shares hereunder are subject to the
following conditions:

              (a)   If, at the time this Agreement is executed and delivered,
it is necessary for the registration statement or a post-effective amendment
thereto (or an Abbreviated Registration Statement) to be declared effective
before the offering of the Shares may commence, the registration statement or
such post-effective amendment or Abbreviated Registration Statement shall have
become effective not later than 5:30 P.M., New York City time, on the date
hereof, or at such later date and time as shall be





                                     - 23 -
<PAGE>   24
consented to in writing by you;  all filings, if any, required by Rules 424 and
430A under the Act shall have been timely made; no stop order suspending the
effectiveness of the registration statement shall have been issued and no
proceeding for that purpose shall have been instituted or, to the knowledge of
the Company or any Underwriter, threatened by the Commission, and any request
of the Commission for additional information (to be included in the
registration statement or the prospectus or otherwise) shall have been complied
with to your reasonable satisfaction.

              (b)   Subsequent to the effective date of this Agreement, there
shall not have occurred (i) any change, or any development involving a
prospective change, in or affecting the condition (financial or other),
business, properties, net worth, or results of operations of the Company not
contemplated by the Prospectus, which in your reasonable opinion, as
Representatives of the several Underwriters, would materially, adversely affect
the market for the Shares, or (ii) any event or development relating to or
involving the Company or any officer or director of the Company or any Selling
Stockholder which makes any statement made in the Prospectus untrue or which,
in the opinion of the Company and its counsel or the Underwriters and their
counsel, requires the making of any addition to or change in the Prospectus in
order to state a material fact required by the Act or any other law to be
stated therein or necessary in order to make the statements therein not
misleading, if amending or supplementing the Prospectus to reflect such event
or development, in your reasonable opinion, as Representatives of the several
Underwriters, would materially adversely affect the market for the Shares.

              (c)   You shall have received on the Closing Date, an opinion of
Wildman, Harrold, Allen & Dixon, counsel for the Company and the Selling
Stockholders, dated the Closing Date and addressed to you, as Representatives
of the several Underwriters, to the effect that:

                    (i)   The Company is a corporation duly incorporated and
validly existing in good standing under the laws of the State of Delaware with
full corporate power and authority to own, lease and operate its properties and
to conduct its business as described in the Registration Statement and the
Prospectus (and any amendment or supplement thereto), and is duly registered
and qualified to conduct its business and is in good standing in each
jurisdiction or place where the nature of its properties or the conduct of its
business requires such registration or qualification, except where the failure
so to register or qualify does not have a material adverse effect on the
condition (financial or other), business, properties, net worth or results of
operations of the Company.  The Company does not own or control, directly or
indirectly, any subsidiary (as defined in Rule 405 promulgated under the Act).





                                     - 24 -

                    (ii)  The authorized and outstanding capital stock of the
Company is as set forth under the caption "Capitalization" in the Prospectus;

by the Company hereunder have been duly authorized and, when issued and
delivered to the Underwriters against payment therefor in accordance with the
terms hereof, will be validly issued, fully paid and nonassessable and free of
any preemptive, or to the best knowledge of such counsel, similar rights that
entitle or will entitle any person to acquire any Shares upon the issuance
thereof by the Company;

                    (v)   The form of certificates for the Shares conforms to
the requirements of the Delaware General Corporation Law;

                    (vi)  The Registration Statement and all post-effective

knowledge of such counsel, no stop order suspending the effectiveness of the
Registration Statement has been issued and no proceedings for that purpose are
pending before or contemplated by the Commission; and any required filing of
the Prospectus pursuant to Rule 424(b) has been made in accordance with Rule
424(b);

                    (vii) The Company has corporate power and authority to 
enter into this Agreement and to issue, sell and deliver the Shares to be
sold by it to the Underwriters as provided herein, and this Agreement has been
duly authorized, executed and delivered by the Company and is a valid, legal
and binding agreement of the Company, enforceable against the Company in
accordance with its terms, except as enforcement of rights to indemnity and
contribution hereunder may be limited by Federal or state securities laws or by
general equitable principles and subject to the qualification that the
enforceability of the Company's obligations hereunder may be limited by
bankruptcy, fraudulent conveyance, insolvency, reorganization, moratorium, and
other laws relating to or affecting creditors' rights generally and by general
equitable principles;

                   (viii) The Company is not in violation of its
certificate of incorporation or bylaws, or other organizational documents, or

                                     - 25 -
<PAGE>   26

in the performance of any material obligation, agreement or condition contained
in any bond, debenture, note or other evidence of indebtedness, except as may
be disclosed in the Prospectus;

                    (ix)  None of the offer, sale or delivery of the Shares by
the Company, the execution, delivery or performance of this Agreement,
compliance by the Company with the provisions hereof, or consummation by the
Company of the transactions contemplated hereby (A) conflicts with or
constitutes a breach of, or a default under, the certificate of incorporation
or bylaws, or other organizational documents, of the Company, or any agreement,
indenture, lease or other instrument to which the Company is a party or by
which it or any of its properties is bound that is an exhibit to the
Registration Statement, or that is material and that is known to such counsel,
(B) will result in the creation or imposition of any lien, charge or
encumbrance upon any property or assets of the Company under any agreement,
indenture, lease or other instrument to which the Company is a party or by
which it or any of its properties is bound that is an exhibit to the
Registration Statement, or that is material and that is known to such counsel,
or (C) will result in any violation of any existing law, regulation, ruling
(assuming compliance with all applicable state securities and Blue Sky laws),
judgment, injunction, order or decree known to such counsel, applicable to the
Company or any of its properties, except for any violation which, individually
or in the aggregate, could not have a material adverse effect on the condition
(financial or other), business, net worth or results of operations of the
Company;

                    (x)   No consent, approval, authorization or other order
of, or registration or filing with, any court, regulatory body, administrative
agency or other governmental body, agency, or official is required on the part
of the Company (except as have been obtained under the Act and the Exchange Act
or such as may be required under state securities or Blue Sky laws governing
the purchase and distribution of the Shares) for the valid issuance and sale of
the Shares by the Company to the Underwriters as contemplated by this
Agreement;

                    (xi)  The Registration Statement and the Prospectus and any
supplements or amendments thereto (except for the financial statements and the
notes thereto and the schedules and other financial data included therein, as
to which such counsel need not express any opinion) comply as to form in all
material respects with the requirements of the Act;

                    (xii) To the best knowledge of such counsel, (A)
other than as described or contemplated in the Prospectus (or any supplement
thereto), there are no legal or governmental proceedings pending or threatened
against the Company, or to which the Company or any of its property, is
subject, which are required to be





                                     - 26 -
<PAGE>   27
described in the Registration Statement or Prospectus (or any amendment or
supplement thereto) and (B) there are no agreements, contracts, indentures,
leases or other instruments, that are required to be described in the

not described or filed as required, as the case may be;

                   (xiii) To the best knowledge of such counsel, the Company 
is not in violation of any law, ordinance, administrative or governmental rule
or regulation applicable to the Company or of any decree of any court or
governmental agency or body having jurisdiction over the Company, except for
any violation which, individually or in the aggregate, could not have a
material adverse effect on the condition (financial or other), business, net
worth or results of operations of the Company;

                    (xiv) The statements in the Registration Statement and 
Prospectus, insofar as they are descriptions of contracts, agreements or other
legal documents, or refer to statements of law or legal conclusions, are
accurate and present fairly the information required to be shown;

                    (xv)  This Agreement and the Custody Agreement have each
been duly executed and delivered by or on behalf of each of the Selling
Stockholders and are valid and binding agreements of each Selling Stockholder
enforceable against each Selling Stockholder in accordance with their terms,
except to the extent that enforceability may be limited by applicable
bankruptcy, insolvency or other similar laws relating to or affecting
creditors' rights and remedies generally and except as enforcement of rights to
indemnity and contribution hereunder may be limited by Federal or state
securities laws or by general equitable principles;

                    (xvi) Each Selling Stockholder has full legal right, 
power and authorization, and any approval required by law, to sell, assign,
transfer and deliver valid and clear title to the Shares which such Selling
Stockholder has agreed to sell pursuant to this Agreement;

                   (xvii) The execution and delivery of this Agreement
and the Custody Agreement by the Selling Stockholders and the consummation of
the transactions contemplated hereby and thereby will not conflict with,
violate, result in a breach of or constitute a default under the terms or
provisions of any agreement, indenture, mortgage or other instrument known to
such counsel to which any Selling Stockholder is a party or by which any of
them or any of their assets or property is bound, or any court order or decree
known to such counsel, or any law, rule, or regulation applicable to





                                     - 27 -
<PAGE>   28
any Selling Stockholder or to any of the property or assets of any Selling
Stockholder;

                    (xviii)  Assuming the Underwriters purchase such
Shares for value, in good faith and without notice of any adverse claim, upon
delivery of the Shares to be sold by the Selling Stockholders pursuant to this
Agreement against payment therefor as contemplated herein the Underwriters will
acquire valid title to such Shares free and clear of any lien, claim, community
property right, voting trust agreement, security interest, or other
encumbrance, restriction on transfer or other defect in title; and

                    (xix)    Each of SPR Chicago, Inc., SPR-Wisconsin,
Inc., SPR Tulsa, Inc., Systems Inc. and Data Flex validly elected to be an S
corporation under Section 1362 of the Internal Revenue Code of 1986, as
amended, and any corresponding provision of state, local or foreign law and
since January 14, 1994, with respect to SPR Chicago, Inc., [OCTOBER __, 1994],
with respect to SPR-Wisconsin, Inc., September 15, 1994, with respect to SPR
Tulsa, Inc., [___________, 199_], with respect to Systems Inc., and October 29,
1990, with respect to Data Flex, each such S corporation election has continued
in full force and effect without interruption through the date hereof.

                    (xx)     The Reorganizations have been consummated and the
Company possesses all necessary consents, approvals, assignments and other
authorizations of (i) any governmental authorities and creditors with
jurisdiction over any of the Constituent Corporations or the Company and (ii)
material lessors, clients, vendors and other third parties doing business with
any of the parties to the Merger Agreements that were and are necessary for the
Company to continue the businesses of each of the Constituent Corporations,
without interruption or delay.  Other than as described in the financial
statements contained in the Prospectus, the Company will not incur any material
liability for the payment of any taxes as a result of the Reorganizations.

                    (xxi)    Such counsel shall further state that, based
upon such counsel's participation in the preparation of the Registration
Statement and the Prospectus, and any amendment or supplement thereto, and upon
such counsel's review and discussion of the contents thereof, but without
independent check or verification or the accuracy or completeness thereof
except as specified, nothing has come to the attention of such counsel that has
caused them to believe that the Registration Statement at the time the
Registration Statement became effective, or the Prospectus, as of its date and
as of the Closing Date or the Option Closing Date, as the case may be (except
for financial statements and the notes thereto and the schedules and other
financial data included therein), contained an untrue statement of a material
fact or omitted to state a material





                                     - 28 -
<PAGE>   29
fact required to be stated therein or necessary to make the statements therein
not misleading or that any amendment or supplement to the Prospectus (except
for financial statements and the notes thereto and the schedules and other
financial data included therein), as of its respective date, and as of the
Closing Date or the Option Closing Date, as the case may be, contained any
untrue statement of a material fact or omitted to state a material fact
necessary in order to make the statements therein, in the light of the
circumstances under which they were made, not misleading.

         In rendering their opinion as aforesaid, counsel may rely upon an
opinion or opinions, each dated the Closing Date, of other counsel retained by
them or the Company as to laws of any jurisdiction other than the United States
or the States of Illinois or Delaware, provided that (1) each such local
counsel is acceptable to the Representatives, (2) such reliance is expressly
authorized by each opinion so relied upon and a copy of each such opinion is
delivered to the Representatives and is, in form and substance, satisfactory to
them and their counsel, and (3) counsel shall state in their opinion that they
believe that they and the Underwriters are justified in relying thereon.

              (d)   You shall have received on the Closing Date an opinion of
Neal, Gerber & Eisenberg, counsel for the Underwriters, dated the Closing Date
and addressed to you, as Representatives of the several Underwriters, with
respect to the matters referred to in clauses (v), (vii), (viii), (xii) and
(xx) of the foregoing paragraph (c) and such other related matters as you may
request.

              (e)   You shall have received letters addressed to you, as
Representatives of the several Underwriters, and dated the date hereof and the
Closing Date, from Arthur Andersen LLP, independent certified public
accountants, substantially in the forms heretofore approved by you.  If (i) the
letter from Arthur Andersen LLP dated the date hereof discloses any material
adverse decreases or increases, as the case may be, in the specified items that
are not disclosed in the Prospectus, or (ii) the letter from Arthur Andersen
LLP dated the Closing Date discloses any material adverse decreases or
increases, as the case may be, in the specified items from its letter dated the
date hereof or that are not disclosed in the Prospectus, then the Company shall
explain and substantiate such decreases or increases to the reasonable
satisfaction of the Underwriters.  If, in the reasonable judgment of the
Underwriters, such increases or decreases make it impracticable or inadvisable
to proceed with the public offering or the delivery of the Shares on the terms
and in the manner contemplated by the Prospectus, the Representatives may
terminate this Agreement.

              (f)   (i) No stop order suspending the effectiveness of the
Registration Statement shall have been issued and no proceedings for





                                     - 29 -
<PAGE>   30
that purpose shall have been taken or, to the knowledge of the Company, shall
be contemplated by the Commission at or prior to the Closing Date; (ii) there
shall not have been any change in the capital stock of the Company nor any
material increase in the short-term or long-term debt of the Company (other
than in the ordinary course of business) from that set forth or contemplated in
the Registration Statement or the Prospectus (or any amendment or Supplement
thereto); (iii) there shall not have been, since the respective dates as of
which information is given in the Registration Statement and the Prospectus (or
any amendment or supplement thereto), except as may otherwise be stated in the
Registration Statement and Prospectus (or any amendment or supplement thereto),
any material adverse change in the condition (financial or other), business,
properties, net worth or results of operations of the Company; (iv) the Company
shall not have any liabilities or obligations, direct or contingent (whether or
not in the ordinary course of business), that are material to the Company,
other than those reflected in the Registration Statement or the Prospectus (or
any amendment or supplement thereto); and (v) all the representations and
warranties of the Company contained in this Agreement shall be true and correct
on and as of the date hereof and on and as of the Closing Date as if made on
and as of the Closing Date, and you shall have received a certificate, dated
the Closing Date and signed by the chief executive officer and the chief
financial officer of the Company (or such other officers as are acceptable to
you), to the effect set forth in this Section 10(f) and in Section 10(g)
hereof.

              (g)   The Reorganizations shall have been consummated and the
Company shall possesses all necessary consents, approvals, assignments and
other authorizations of (i) any governmental authorities and creditors with
jurisdiction over any of the Constituent Corporations or the Company and (ii)
material lessors, clients, vendors and other third parties doing business with
any of the parties to the Merger Agreements that were and are necessary for the
Reorganizations to become effective and for the Company to continue the
businesses of each of the Constituent Corporations, without interruption or
delay.

              (h)   The Company shall not have failed at or prior to the
Closing Date to have performed or complied, in all material respects, with any
of its agreements herein contained and required to be performed or complied
with by it hereunder at or prior to the Closing Date.

              (i)   All the representations and warranties of the Selling
Stockholders contained in this Agreement shall be true and correct on and as of
the date hereof and on and as of the Closing Date as if made on and as of the
Closing Date, and you shall have received a certificate, dated the Closing Date
and signed by or on behalf of





                                     - 30 -

the Selling Stockholders to the effect set forth in this Section 10(i) and in
Section 10(j) hereof.

              (j)   The Selling Stockholders shall not have failed at or prior
to the Closing Date to have performed or complied, in all material respects,
with any of their agreements herein contained and required to be performed or
complied with by them hereunder at or prior to the Closing Date.

              (k)   The Shares shall have been listed or approved for listing
upon notice of issuance on the Nasdaq National Market.

              (l)   You shall have received a Lock-Up Letter executed by each
of the current officers and directors of the Company and by each of its current
stockholders.

         All such opinions, certificates, letters and other documents will be
in compliance with the provisions hereof only if they are satisfactory in form
and substance to you and your counsel.

         Any certificate or document signed by any officer of the Company or
any Attorney-in-Fact or any Selling Stockholder and delivered to you, as
Representatives of the Underwriters, or to counsel for the Underwriters, shall
be deemed a representation and warranty by the Company, the Selling
Stockholders or the particular Selling Stockholder, as the case may be, to each
Underwriter as to the statements made therein.

         The several obligations of the Underwriters to purchase Additional
Shares hereunder are subject to the satisfaction on and as of any Option
Closing Date of the conditions set forth in this Section 10, except that, if
any Option Closing Date is other than the Closing Date, the certificates,
opinions and letters referred to in paragraphs (c) through (i) shall be dated
the Option Closing Date in question and the opinions called for by paragraphs
(c), (d) and (e) shall be revised to reflect the sale of Additional Shares.

         11.  Expenses.  The Company agrees to pay the following costs and
expenses and all other costs and expenses incident to the performance by it of
its obligations hereunder: (i) the preparation, printing or reproduction, and

in the first sentence of Section 5(f) hereof; (iii) the preparation, printing,

the listing of the Shares on the Nasdaq National Market; (vi) the registration

the reasonable fees, expenses and disbursements of counsel for the Underwriters
relating to the preparation, printing or reproduction, and delivery of the
preliminary and supplemental Blue Sky Memoranda and such registration and
qualification); (vii) the filing fees and the fees and expenses of counsel for
the Underwriters in connection with any filings required to be made with the

the fees and expenses of the Company's accountants and the fees and expenses of

Underwriters will pay their own costs and expenses in connection with the
offering contemplated hereby, including fees and disbursements of their
counsel, travel and entertainment expenses, stock transfer taxes payable on
resale of any of the Shares by them and any advertising expenses connected with
any offers they may make, including, but not limited to, the "tombstone"
advertisement and expenses associated with the preparation of prospectus
memorabilia, if any.

         12.  Effective Date of Agreement.  This Agreement shall become
effective upon the execution and delivery hereof by the parties hereto;
provided, however, that if, at the time this Agreement is executed and
delivered, it is necessary for the registration statement or a post-effective
amendment thereto or an Abbreviated Registration Statement to be declared
effective before the offering of the Shares may commence, then the
effectiveness of this Agreement shall be delayed until notification of the
effectiveness of the registration statement or such post-effective amendment or
Abbreviated Registration Statement has been released by the Commission.  Until
such time as this Agreement shall have become effective, it may be terminated
by the Company, by notifying you, or by you, as Representatives of the several
Underwriters, by notifying the Company and the Selling Stockholders.

<PAGE>   33
         If any one or more of the Underwriters shall fail or refuse to
purchase Shares which it or they are obligated to purchase hereunder on the
Closing Date, and the aggregate number of Shares which such defaulting
Underwriter or Underwriters are obligated but fail or refuse to purchase is not
more than one-tenth of the aggregate number of Shares which the Underwriters
are obligated to purchase on the Closing Date, each non-defaulting Underwriter
shall be obligated, severally, in the proportion which the number of Firm
Shares set forth opposite its name in Schedule II hereto bears to the aggregate
number of Firm Shares set forth opposite the names of all non-defaulting
Underwriters or in such other proportion as you may specify in accordance with
Section 20 of the Master Agreement Among Underwriters of Smith Barney Inc., to
purchase the Shares which such defaulting Underwriter or Underwriters are
obligated, but fail or refuse, to purchase.  If any one or more of the
Underwriters shall fail or refuse to purchase Shares which it or they are
obligated to purchase on the Closing Date and the aggregate number of Shares
with respect to which such default occurs is more than one-tenth of the
aggregate number of Shares which the Underwriters are obligated to purchase on
the Closing Date and arrangements satisfactory to you and the Company for the
purchase of such Shares by one or more non- defaulting Underwriters or other
party or parties approved by you and the Company are not made within 36 hours
after such default, this Agreement will terminate without liability on the part
of any non-defaulting Underwriter, the Company or any Selling Stockholder.  In
any such case which does not result in termination of this Agreement, either
you or the Company shall have the right to postpone the Closing Date, but in no
event for longer than seven days, in order that the required changes, if any,
in the Registration Statement and the Prospectus or any other documents or
arrangements may be effected.  Any action taken under this paragraph shall not
relieve any defaulting Underwriter from liability in respect of any such
default of any such Underwriter under this Agreement.  The term "Underwriter"
as used in this Agreement includes, for all purposes of this Agreement, any
party not listed in Schedule II hereto who, with your approval and the approval
of the Company, purchases Shares which a defaulting Underwriter is obligated,
but fails or refuses, to purchase.

         Any notice under this Section 12 may be given by telegram, telecopy or
telephone but shall be subsequently confirmed by letter.

         13.  Termination of Agreement.  This Agreement shall be subject to
termination in your absolute discretion, without liability on the part of any
Underwriter to the Company or any Selling Stockholder, by notice to the
Company, if prior to the Closing Date or any Option Closing Date (if different
from the Closing Date and then only as to the Additional Shares), as the case
may be, (i) trading in securities generally on the New York Stock





                                     - 33 -

Exchange, American Stock Exchange or the Nasdaq National Market shall have been
suspended or materially limited, (ii) a general moratorium on commercial
banking activities in New York or Illinois shall have been declared by either
federal or state authorities, or (iii) there shall have occurred any outbreak
or escalation of hostilities or other international or domestic calamity,
crisis or change in political, financial or economic conditions, the effect of
which on the financial markets of the United States is such as to make it, in
your reasonable judgment, impracticable or inadvisable to commence or continue
the offering of the Shares at the offering price to the public set forth on the
cover page of the Prospectus or to enforce contracts for the resale of the
Shares by the Underwriters.  Notice of such termination may be given to the
Company by telegram, telecopy or telephone and shall be subsequently confirmed
by letter.

         14.  Information Furnished by the Underwriters.  The statements set
forth in the last paragraph on the cover page, the stabilization legend on the
inside cover page, and the statements in the first and third paragraphs under
the caption "Underwriting" in any Prepricing Prospectus and in the Prospectus,
constitute the only information furnished by or on behalf of the Underwriters
through you as such information is referred to in Sections 7(b) and 9 hereof.

         15.  Miscellaneous.  Except as otherwise provided in Sections 5, 12
and 13 hereof, notice given pursuant to any provision of this Agreement shall
be in writing and shall be delivered (i) if to the Company, at the office of
the Company at 2015 Spring Road, Suite 750, Oak Brook, Illinois 60521,
Attention: Robert M. Figliulo, President; or (ii) if to the Selling
Stockholders, at ____________, Attention: [INSERT NAME AND TITLE], or (iii) if
to you, as Representatives of the several Underwriters, care of Smith Barney
Inc., 388 Greenwich Street, New York, New York 10013, Attention: Manager,
Investment Banking Division.

         This Agreement has been and is made solely for the benefit of the
several Underwriters, the Company, its directors and officers, and the other
controlling persons referred to in Section 9 hereof and their respective
successors and assigns, to the extent provided herein, and no other person
shall acquire or have any right under or by virtue of this Agreement.  Neither
the term "successor" nor the term "successors and assigns" as used in this
Agreement shall include a purchaser from any Underwriter of any of the Shares
in his status as such purchaser.

         16.  Applicable Law; Counterparts.  This Agreement shall be governed
by and construed in accordance with the laws of the State of New York
applicable to contracts made and to be performed within the State of New York.

constitute one and the same instrument.  If signed in counterparts, this
Agreement shall not become effective unless at least one counterpart hereof

stockholders, of this Corporation, as the case may be, and also on this
Corporation.

EIGHTH:  The books of the Corporation may be kept (subject to any provision
contained in the statutes) outside the State of Delaware at such place or
places as may be designated from time to time by the Board of Directors or in
the By-Laws of the Corporation.  Election of directors need not be by ballot

stockholders may be held within or outside of the State of Delaware, as the
By-Laws of the Corporation may provide.

NINTH:  A director of the Corporation shall not be personally liable to the
Corporation or its stockholders for monetary damages for breach of fiduciary

extent authorized by the General Corporation Law of the State of Delaware, as
so amended.

         Any repeal or modification of this Article shall not adversely affect
any right or protection of a director of the Corporation existing at the time

Stock to elect additional directors under specified circumstances, the number

Directors pursuant to a resolution adopted by a majority of the Whole Board.

mean the total number of authorized directors whether or not there exist any
vacancies in previously authorized directorships.

                 B.       Subject to the rights of the holders of any series of
Preferred Stock then outstanding, newly created directorships resulting from
any increase in the authorized number of directors or any vacancies in the
Board of Directors resulting from death, resignation, retirement,
disqualification, removal from office or other cause shall, unless otherwise
provided by law or by resolution of the Board of Directors, be filled only by a
majority vote of the directors then in office, though less than a quorum, and
directors so chosen shall hold office until the next annual meeting of
stockholders and until their successors shall be duly elected and qualified.
No decrease in the authorized number of directors shall shorten the term of any
incumbent director.

                 C.       Advance notice of stockholder nominations for the
election of directors and of business to be brought by stockholders before any
meeting of the stockholders of the Corporation shall be given in the manner
provided in the By-laws of the Corporation.

                 D.       Subject to the rights of the holders of any series of
Preferred Stock then outstanding, any directors, or the entire Board of
Directors, may be removed from office at any time, but only for cause and only
by the affirmative vote of the holders of at least sixty-six percent (66%) of
the voting power of all of the then-outstanding shares of capital stock of the
Corporation entitled to vote generally in the election of directors, voting
together as a single class.

ELEVENTH:  Indemnification of Directors and Officers.

                 A.       Right to Indemnification.  Each person who was or is
made a party or is threatened to be made a party to or is otherwise involved in
any action, suit or proceeding, whether civil, criminal, administrative or
investigative (hereinafter a "PROCEEDING"), by reason of the fact that he or
she is or was a director or an officer of the Corporation or is or was serving
at the request of the Corporation as a director, officer, employee or agent of
another corporation or of a partnership, joint venture, trust or other
enterprise, including service with





                                      -3-
<PAGE>   4
respect to an employee benefit plan (hereinafter an "INDEMNITEE"), whether the
basis of such proceeding is alleged action in an official capacity as a
director, officer, employee or agent or in any other capacity while serving as
a director, officer, employee or agent, shall be indemnified and held harmless
by the Corporation to the fullest extent authorized by the Delaware General
Corporation Law, as the same exists or may hereafter be amended (but, in the
case of any such amendment, only to the extent that such amendment permits the
Corporation to provide broader indemnification rights than such law permitted
the Corporation to provide prior to such amendment), against all expense,
liability and loss (including attorneys' fees, judgments, fines, ERISA excise
taxes or penalties and amounts paid in settlement) reasonably incurred or
suffered by such indemnitee in connection therewith; provided, however, that,
except as provided in Section C of this ARTICLE ELEVENTH with respect to
proceedings to enforce rights to indemnification, the Corporation shall
indemnify any such indemnitee in connection with a proceeding (or part thereof)
initiated by such indemnitee only if such proceeding (or part thereof) was
authorized by the Board of Directors of the Corporation.

                 B.       Right to Advancement of Expenses.  The right to
indemnification conferred in Section A of this ARTICLE ELEVENTH shall include
the right to be paid by the Corporation the expenses (including attorneys'
fees) incurred in defending any such proceeding in advance of its final
disposition (hereinafter an "ADVANCEMENT OF EXPENSES"); provided, however,
that, if the Delaware General Corporation Law requires, an advancement of
expenses incurred by an indemnitee in his or her capacity as a director or
officer (and not in any other capacity in which service was or is rendered by
such indemnitee, including, without limitation, service to an employee benefit
plan) shall be made only upon delivery to the Corporation of an undertaking
(hereinafter an "UNDERTAKING"), by or on behalf of such indemnitee, to repay
all amounts so advanced if it shall ultimately be determined by final judicial
decision from which there is no further right to appeal (hereinafter a "FINAL
ADJUDICATION") that such indemnitee is not entitled to be indemnified for such
expenses under this Section B or otherwise.  The rights to indemnification and
to the advancement of expenses conferred in Sections A and B of this ARTICLE
ELEVENTH shall be contract rights and such rights shall continue as to an
indemnitee who has ceased to be a director, officer, employee or agent and
shall inure to the benefit of the indemnitee's heirs, executors and
administrators.

                 C.       Right of Indemnitee to Bring Suit.  If a claim under
Section A or B of this ARTICLE ELEVENTH is not paid in full by the corporation
within sixty (60) days after a written claim has been received by the
Corporation, except in the case of a claim for an advancement of expenses, in
which case the applicable period shall be twenty (20) days, the indemnitee may
at any time thereafter bring suit against the Corporation to recover the unpaid
amount of the claim.  If successful in whole or in part in any such suit, or in
a suit brought by the Corporation to recover an advancement of expenses
pursuant to the terms of an undertaking, the indemnitee shall be entitled to be
paid also the expense of prosecuting or defending such suit.  In (i) any suit
brought by the indemnitee to enforce a right to indemnification hereunder (but
not in a suit brought by the indemnitee to enforce a right to an advancement of
expenses) it shall be a defense that, and (ii) in any suit brought by the
Corporation to recover an advancement of expenses pursuant to the terms of an
undertaking, the Corporation shall be entitled to recover





                                      -4-
<PAGE>   5
such expenses upon a final adjudication that, the indemnitee has not met any
applicable standard for indemnification set forth in the Delaware General
Corporation Law.  Neither the failure of the Corporation (including its Board
of Directors, independent legal counsel, or its stockholders) to have made a
determination prior to the commencement of such suit that indemnification of
the indemnitee is proper in the circumstances because the indemnitee has met
the applicable standard of conduct set forth in the Delaware General
Corporation Law, nor an actual determination by the Corporation (including its
Board of Directors, independent legal counsel, or its stockholders) that the
indemnitee has not met such applicable standard of conduct, shall create a
presumption that the indemnitee has not met the applicable standard of conduct
or, in the case of such a suit brought by the indemnitee, be a defense to such
suit.  In any suit brought by the indemnitee to enforce a right to
indemnification or to an advancement of expenses hereunder, or brought by the
Corporation to recover an advancement of expenses pursuant to the terms of an
undertaking, the burden of proving that the indemnitee is not entitled to be
indemnified, or to such advancement of expenses, under this Article ELEVENTH or
otherwise shall be on the Corporation.

                 D.       Non-Exclusivity of Rights.  The rights to
indemnification and to the advancement of expenses conferred in this ARTICLE
ELEVENTH shall not be exclusive of any other right which any person may have or
hereafter acquire under any statute, this Certificate of Incorporation, the
Corporation's By-Laws, agreement, vote of stockholders or disinterested
directors or otherwise.

                 E.       Insurance.  The Corporation may maintain insurance,
at its expense, to protect itself and any director, officer, employee or agent
of the Corporation or another corporation, partnership, joint venture, trust or
other enterprise against any expense, liability or loss, whether or not the
Corporation would have the power to indemnify such person against such expense,
liability or loss under the Delaware General Corporation Law.

                 F.       Indemnification of Employees and Agents of the
Corporation.  The Corporation may, to the extent authorized from time to time
by the Board of Directors, grant rights to indemnification and to the
advancement of expenses to any employee or agent of the Corporation to the
fullest extent of the provisions of this ARTICLE ELEVENTH with respect to the
indemnification and advancement of expenses of directors and officers of the
Corporation.

TWELFTH:  No amendment or repeal of Article NINTH or ELEVENTH of this
Certificate of Incorporation shall apply to or have any effect on the right of
any individual referred to in Article NINTH or ELEVENTH for or with respect to
acts or omissions of such individual occurring prior to such amendment or
repeal.

THIRTEENTH:  The Corporation reserves the right to amend, alter, change or
repeal any provision contained in this Certificate of Incorporation, in the
manner now or hereafter prescribed by statute, and all rights conferred upon
stockholders herein are granted subject to this reservation.

         SECTION 7.       BUSINESS TO BE TRANSACTED.

                 (a)        Nominations of persons for election to the board of
directors of the corporation and the proposal of business to be transacted by
the stockholders may be made at an annual meeting of stockholders (i) pursuant
to the corporation's notice with respect to such meeting, (ii) by or at the
direction of the board of directors or (iii) by any stockholder of the
corporation who was a stockholder of record at the time of giving of the notice
provided for in this Section 7, who is entitled to vote at the meeting and who
has complied with the notice procedures set forth in this Section 7.

                 (b)      For nominations or other business to be properly
brought before an annual meeting by a stockholder pursuant to clause (iii) of
paragraph (a) of this Section 7, the stockholder must have given timely notice
thereof in writing to the Secretary of the corporation and such business must
be a proper matter for stockholder action under the General Corporation Law of
the State of Delaware.  To be timely, a stockholder's notice shall be delivered
to the Secretary at the principal executive offices of the corporation not less
than sixty (60) days nor more than ninety (90) days prior to the first
anniversary of the preceding year's annual meeting of stockholders; provided,
however, that if the date of the annual meeting is advanced more than thirty
(30) days prior to or delayed by more than sixty (60) days after such
anniversary date, notice by the stockholder to be timely must be so delivered
not earlier than the 90th day prior to such annual meeting and not later than
the close of business on the later of the 60th day prior to such annual meeting
or the 10th day following the day on which public announcement of the date of
such meeting is first made.  Such stockholder's notice shall set forth (i) as
to each person whom the stockholder proposes to nominate for election or
reelection as a director all information relating to such person that is
required to be disclosed in solicitations of proxies for election of directors,
or is otherwise required, in each case pursuant to Regulation 14A under the
Securities Exchange Act of 1934, as amended (the "Exchange Act") (including
such person's





                                      -2-
<PAGE>   6
written consent to being named in the proxy statement as a nominee and to
serving as a director if elected); (ii) as to any other business that the
stockholder proposes to bring before the meeting, a brief description of such
business, the reasons for conducting such business at the meeting and any
material interest in such business of such stockholder and the beneficial
owner, if any, on whose behalf the proposal is made; and (iii) as to the
stockholder giving the notice and the beneficial owner, if any, on whose behalf
the nomination or proposal is made (A) the name and address of such
stockholder, as they appear on the corporation's books, and of such beneficial
owner and (B) the class and number of shares of the corporation which are owned
beneficially and of record by such stockholder and such beneficial owner.

                 (c)      Notwithstanding anything in the second sentence of
paragraph (B) of this by-law to the contrary, in the event that the number of
directors to be elected to the board of directors of the corporation is
increased and there is no public announcement naming all of the nominees for
director or specifying the size of the increased board of directors made by the
corporation at least seventy (70) days prior to the first anniversary of the
preceding year's annual meeting, a stockholder's notice required by this by-law
shall also be considered timely, but only with respect to nominees for any new
positions created by such increase, if it shall be delivered to the Secretary
at the principal executive offices of the corporation not later than the close
of business on the 10th day following the day on which such public announcement
is first made by the corporation.

                 (d)      Only persons nominated in accordance with the
procedures set forth in this Section 7 shall be eligible to serve as directors
and only such business shall be conducted at an annual meeting of stockholders
as shall have been brought before the meeting in accordance with the procedures
set forth in this Section 7.  The chair of the meeting shall have the power and
the duty to determine whether a nomination or any business proposed to be
brought before the meeting has been made in accordance with the procedures set
forth in these by-laws and, if any proposed nomination or business is not in
compliance with these by-laws to declare that such defective proposed business
or nomination shall not be presented for stockholder action at the meeting and
shall be disregarded.

                 (e)      For purposes of this section, "public announcement"
shall mean disclosure in a press release reported by the Dow Jones News
Service, Associated Press or a comparable national news service or in a
document publicly filed by the corporation with the Securities and Exchange
Commission pursuant to Section 13, 14 or 15(d) of the Exchange Act.

                 (f)      Notwithstanding the foregoing provisions of this
by-law, a stockholder shall also comply with all applicable requirements of the
Exchange Act and the rules and regulations thereunder with respect to matters
set forth in this by-law.  Nothing in this Section 7 shall be deemed to affect
any rights of stockholders to request inclusion of proposals in the
corporation's proxy statement pursuant to Rule 14a-8 under the Exchange Act.

         SECTION 8.       QUORUM AND ADJOURNMENTS.  A majority of the shares
entitled to vote, present in person and represented by proxy, shall constitute
a quorum at all meetings of the





                                      -3-
<PAGE>   7
stockholders for the transaction of business except as otherwise provided by
statute or by the certificate of incorporation; provided, however, that with
respect to any matter on which any class of stock is entitled to vote
separately as a class, the holders of a majority of the voting power
represented by the issued and outstanding shares of such class, present in
person and represented by proxy, shall constitute a quorum for purposes of such
matter.  If, however, such quorum shall not be present or represented at any
meeting of the stockholders, the stockholders entitled to vote thereat, present
in person or represented by proxy, shall have the power to adjourn the meeting
from time to time, without notice other than announcement at the meeting, until
a quorum shall be present or represented.  At such adjourned meeting at which a
quorum shall be present or represented, any business may be transacted which
might have been transacted at the meeting as originally noticed.  If the
adjournment is for more than thirty days, or if after the adjournment a new
record date is fixed for the adjourned meeting, a notice of the adjourned
meeting shall be given to each stockholder of record entitled to vote at the
meeting.

         SECTION 9.       VOTE REQUIRED.  When a quorum is present at any
meeting, the vote of the holders of a majority of the voting power present in
person or represented by proxy shall decide any question brought before such
meeting, except for (i) the election of directors as provided for in Article
III hereof, and (ii) any question upon which, by express provision of a statute
or of the certificate of incorporation, a different vote is required in which
case such express provision shall govern and control the decision of such
question.

         SECTION 10.      VOTING RIGHTS.  Except to the extent required by
statute or the certificate of incorporation or any amendments thereto, each
holder of Common Stock shall at every meeting of the stockholders be entitled
to one vote in person or by proxy for each share of Common Stock held by such
stockholder.

         SECTION 11.      PROXIES.   Each stockholder entitled to vote at a
meeting of stockholders or to express consent or dissent to corporate action in
writing without a meeting may authorize another person or persons to act for
him by proxy, but no such proxy shall be voted or acted upon after three years
from its date, unless the proxy provides for a longer period.

person or represented by proxy at the meeting and entitled to vote in the
election of directors.  The directors shall be elected in this manner at the
annual meeting of the stockholders, except as provided in Section 2 of this
Article III.  Each director elected shall hold office until a successor is
elected and qualified or until his earlier death, resignation or removal, as
hereinafter provided.  Directors need not be stockholders.

the next annual election and until their successors shall be duly elected and
qualified.  If there are no directors in office, then an election of directors
may be held in the manner provided by statute.

         SECTION 3.       GENERAL POWERS.  The business of the corporation

the number of members of the board of directors then serving.  A quorum shall
be required for any action to be taken at a meeting of the board of directors.
Except as otherwise provided in this Article, the affirmative vote of a
majority of the members of the board of directors at a meeting at which a
quorum is present shall be the act of the board of directors.  If a quorum

         SECTION 8.       RESIGNATIONS.  Any director of the corporation may

who is present at a meeting of the board of directors at which action on any
corporate matter is taken shall be conclusively presumed to have assented to
the action taken unless his dissent shall be entered in the minutes of the
meeting or unless he shall file his written dissent to such action with the
person acting as the secretary of the meeting before the adjournment thereof or
shall forward such dissent by registered mail to the secretary of the
corporation immediately after the adjournment of the meeting.  Such right to
dissent shall not apply to a director who voted in favor of such action.

                            COMMITTEES OF DIRECTORS

         SECTION 12.      APPOINTMENT AND POWERS.  The board of directors may,
by resolution passed by a majority of the whole board, designate one or more
committees, each committee to consist of one or more of the directors of the

or the secretary or an assistant secretary of the corporation, certifying the





                                      -9-
<PAGE>   13
number of shares owned by him in the corporation.  If the corporation shall be
authorized to issue more than one class of stock or more than one series of any
class, the powers, designation, preferences and relative, participating,
optional or other special rights of each class of stock or series thereof and
the qualifications, limitations or restrictions of such preferences and/or
rights shall be set forth in full or summarized on the face or back of the
certificate which the corporation shall issue to represent such class or series
of stock, provided that, except as otherwise provided in Section 202 of the
Delaware General Corporation Law, in lieu of the foregoing requirements, there
may be set forth in full or summarized on the face or back of the certificate
which the corporation shall issue to represent such class or series of stock, a
statement that the corporation will furnish without charge to each stockholder
who so requests a statement of the powers, designations, preferences and
relative, participating, optional or other special rights of each class of
stock or series thereof and the qualifications, limitations or restrictions of
such preferences and/or rights.

         SECTION 2.       FACSIMILE SIGNATURES.  Where a certificate is
countersigned (1) by a transfer agent other than the corporation or its
employee, or (2) by a registrar other than the corporation or its employee, any
other signature on the certificate may be facsimile.  In case any officer,
transfer agent or registrar who has signed or whose facsimile signature has
been placed upon a certificate shall have ceased to be such officer, transfer
agent or registrar before such certificate is issued, it may be issued by the
corporation with the same effect as if he were such officer, transfer agent or
registrar at the date of issue.

a new certificate or certificates to be issued in place of any certificate or
certificates theretofore issued by the corporation alleged to have been lost,
stolen or destroyed, upon the making of an affidavit of that fact by the person
claiming the certificate of stock to be lost, stolen or destroyed.  When
authorizing such issue of a new certificate or certificates, the board of
directors may, in its discretion and as a condition precedent to the issuance
thereof, require the owner of such lost, stolen or destroyed certificate or
certificates, or his legal representatives, to advertise the same in such
manner as it shall require and/or to give the corporation a bond in such sums
it may direct to indemnify against any claim that may be made against the
corporation with respect to the certificate alleged to have been lost, stolen
or destroyed.

         SECTION 4.       TRANSFERS OF STOCK.  Upon surrender to the
corporation or the transfer agent of the corporation of a certificate for
shares duly endorsed or accompanied by proper evidence of succession,
assignment or authority to transfer, it shall be the duty of the corporation to
issue a new certificate to the person entitled thereto, cancel the old
certificate and record the transaction upon its books.

         SECTION 5.       FIXING RECORD DATE.  In order that the corporation

                                  ARTICLE VIII

                   INDEMNIFICATION OF DIRECTORS AND OFFICERS

         SECTION 1.       RIGHT TO INDEMNIFICATION.  Each person who was or is
made a party or is threatened to be made a party to or is otherwise involved in
any action, suit or proceeding, whether civil, criminal, administrative or
investigative (hereinafter a "proceeding"), by reason of the fact that he or
she is or was a director or an officer of the corporation or is or was serving
at the request of the corporation as a director, officer, employee or agent of
another corporation or of a partnership, joint venture, trust or other
enterprise, including service with respect to an employee benefit plan
(hereinafter an "indemnitee"), whether the basis of such proceeding is alleged
action in an official capacity as a director, officer, employee or agent or in
any other capacity while serving as a director, officer, employee or agent,
shall be indemnified and held harmless by the corporation to the fullest extent
authorized by the Delaware General Corporation Law, as the same exists or may
hereafter be amended (but, in the case of any such amendment, only to the
extent that such amendment permits the corporation to provide broader
indemnification rights than such law permitted the corporation to provide prior
to such amendment), against all expense, liability and loss (including
attorneys' fees, judgments, fines, ERISA excise taxes or penalties and amounts
paid in settlement) reasonably incurred or suffered by such indemnitee in
connection therewith; provided, however, that, except as provided in Section 3
of this Article VIII with respect to proceedings to enforce rights to
indemnification, the corporation shall indemnify any such indemnitee in
connection with a proceeding (or part thereof) initiated by such indemnitee
only if such proceeding (or part thereof) was authorized by the board of
directors of the corporation.

         SECTION 2.       RIGHT TO ADVANCEMENT OF EXPENSES.  The right to
indemnification conferred in Section 1 of this Article VIII shall include the
right to be paid by the corporation the expenses (including attorneys' fees)
incurred in defending any such proceeding in advance of its final disposition
(hereinafter an "advancement of expenses"); provided, however, that, if the
Delaware General Corporation Law requires, an advancement of expenses incurred
by an indemnitee in his or her capacity as a director or officer (and not in
any other capacity in which





                                      -12-
<PAGE>   16
service was or is rendered by such indemnitee, including, without limitation,
service to an employee benefit plan) shall be made only upon delivery to the
corporation of an undertaking (hereinafter an "undertaking"), by or on behalf
of such indemnitee, to repay all amounts so advanced if it shall ultimately be
determined by final judicial decision from which there is no further right to
appeal (hereinafter a "final adjudication") that such indemnitee is not
entitled to be indemnified for such expenses under this Section 2 or otherwise.
The rights to indemnification and to the advancement of expenses conferred in
Sections 1 and 2 of this Article VIII shall be contract rights and such rights
shall continue as to an indemnitee who has ceased to be a director, officer,
employee or agent and shall inure to the benefit of the indemnitee's heirs,
executors and administrators.

         SECTION 3.       RIGHT OF INDEMNITEE TO BRING SUIT.  If a claim under
Section 1 or 2 of this Article VIII is not paid in full by the corporation
within sixty (60) days after a written claim has been received by the
corporation, except in the case of a claim for an advancement of expenses, in
which case the applicable period shall be twenty (20) days, the indemnitee may
at any time thereafter bring suit against the corporation to recover the unpaid
amount of the claim.  If successful in whole or in part in any such suit, or in
a suit brought by the corporation to recover an advancement of expenses
pursuant to the terms of an undertaking, the indemnitee shall be entitled to be
paid also the expense of prosecuting or defending such suit.  In (a) any suit
brought by the indemnitee to enforce a right to indemnification hereunder (but
not in a suit brought by the indemnitee to enforce a right to an advancement of
expenses) it shall be a defense that, and (b) in any suit brought by the
corporation to recover an advancement of expenses pursuant to the terms of an
undertaking, the corporation shall be entitled to recover such expenses upon a
final adjudication that, the indemnitee has not met any applicable standard for
indemnification set forth in the Delaware General Corporation Law.  Neither the
failure of the corporation (including its board of directors, independent legal
counsel, or its stockholders) to have made a determination prior to the
commencement of such suit that indemnification of the indemnitee is proper in
the circumstances because the indemnitee has met the applicable standard of
conduct set forth in the Delaware General Corporation Law, nor an actual
determination by the corporation (including its board of directors, independent
legal counsel, or its stockholders) that the indemnitee has not met such
applicable standard of conduct, shall create a presumption that the indemnitee
has not met the applicable standard of conduct or, in the case of such a suit
brought by the indemnitee, be a defense to such suit.  In any suit brought by
the indemnitee to enforce a right to indemnification or to an advancement of
expenses hereunder, or brought by the corporation to recover an advancement of
expenses pursuant to the terms of an undertaking, the burden of proving that
the indemnitee is not entitled to be indemnified, or to such advancement of
expenses, under this Article VIII or otherwise shall be on the corporation.

         SECTION 4.       NON-EXCLUSIVITY OF RIGHTS.  The rights to
indemnification and to the advancement of expenses conferred in this Article
VIII shall not be exclusive of any other right which any person may have or
hereafter acquire under any statute, the corporation's certificate of
incorporation, by-laws, agreement, vote of stockholders or disinterested
directors or otherwise.

<PAGE>   17
         SECTION 5.       INSURANCE.  The corporation may maintain insurance,
at its expense, to protect itself and any director, officer, employee or agent
of the corporation or another corporation, partnership, joint venture, trust or
other enterprise against any expense, liability or loss, whether or not the
corporation would have the power to indemnify such person against such expense,
liability or loss under the Delaware General Corporation Law.

         SECTION 6.       INDEMNIFICATION OF EMPLOYEES AND AGENTS OF THE
CORPORATION.  The corporation may, to the extent authorized from time to time
by the board of directors, grant rights to indemnification and to the
advancement of expenses to any employee or agent of the corporation to the
fullest extent of the provisions of this Article with respect to the
indemnification and advancement of expenses of directors and officers of the
corporation.


                                   ARTICLE IX

                                   AMENDMENTS

         These by-laws may be altered, amended or repealed or new by-laws may
be adopted by the stockholders or by the board of directors at any regular
meeting of the board of directors or of the stockholders or at any special
meeting of the board of directors or of the stockholders, if notice of such
alteration, amendment, repeal or adoption of new by-laws be contained in the
notice of such special meeting of the stockholders.

             Re:  REGISTRATION OF 3,105,000 SHARES OF COMMON STOCK
                  $.01 PAR VALUE PER SHARE


Ladies & Gentlemen:

     We have acted as counsel to SPR Inc., a Delaware corporation (the
"Company"), in connection with the preparation of a Registration Statement on
Form S-1, filed by the Company with the Securities and Exchange Commission (the
"Commission") on November 19, 1996, (the "Registration Statement").  The
Registration Statement relates to the proposed sale of up to 3,105,000 shares
of the Company's Common Stock, $.01 par value per share (the "Shares"),
pursuant to an underwriting agreement (the "Underwriting Agreement") to be
entered into among the Company, certain selling stockholders and the
underwriters as described in the Registration Statement.

     We have examined such documents and corporate and other records as we
deemed necessary for the purpose of rendering this opinion, including the
Company's Certificate of Incorporation, the Company's By-Laws, the Registration
Statement pursuant to which the Shares are to be registered under the
Securities Act of 1933, as amended (the "Act"), and records of corporate
proceedings.

     Based upon the foregoing, it is our opinion that upon the execution and
delivery of the Underwriting Agreement by the Company and the selling
stockholders, (i) the 1,666,666 Shares to be offered and sold by the Company,
when sold and delivered against payment as provided in the Underwriting
Agreement, will be duly authorized, validly issued, fully paid and
non-assessable, and (ii) the 1,438,334 Shares to be offered and sold by
certain selling stockholders of the Company pursuant to the Underwriting
Agreement have been duly authorized and validly issued, and are fully paid and
non-assessable.

     We hereby consent to the filing of this opinion with the Commission as an
exhibit to the Registration Statement.  We also consent to the reference to our
firm under the caption "Legal Matters" in the Registration Statement.  In
giving this consent, we do not thereby admit that we are included in the
category of persons whose consent is required under Section 7 of the Act or the
rules and regulations of the Commission.

                                             Very truly yours,

                                             /s/ Wildman, Harrold, Allen & Dixon

         The purpose of the Plan is to provide additional incentive to certain
Employees and Directors who are making and continue to make substantial

them with an opportunity to acquire a proprietary or ownership interest in the
Company through the grant and exercise of options to purchase shares of the
Common Stock of the Company.  It is the judgment of the Board of Directors of
the Company that the acquisition of a proprietary or ownership interest in the
Company by certain Employees will increase their personal interest in its
growth and progress, thereby promoting the interests of the Company and all its
stockholders.  The Company intends that the options granted pursuant to the
Plan may either qualify as "incentive stock options" within the meaning of
Section 422 of the Code, or may not qualify as incentive stock options, to the
extent provided in Sections 4.2(h) and 7.8 hereof.

consisting solely of two or more Non-Employee Directors of the Board.  In the
event that the Board does delegate such authority to a Committee, it may also
at any time terminate that authority and resume the exclusive control and

appointment of the Board, (c) the members of the Committee shall serve at the

constitute a contract of employment between the Company (or any subsidiary) and
the Employee and shall not affect the right of the Company to terminate the
employment of the Employee.

share of Common Stock on the date such Non- Statutory Stock Option or Stock
Appreciation Right is granted.  The purchase price per share of Common Stock
subject to an Incentive Stock Option shall not be less than the Fair Market
Value of a share of Common Stock on the date





                                      -5-
<PAGE>   6
such Incentive Stock Option is granted.  The number shares and the purchase
price per share shall be subject to adjustment as provided in Article X.

         7.2     NON-TRANSFERABILITY OF OPTIONS:  Each Option Agreement shall
provide that the Option and Stock Appreciation Rights, if any, granted therein
shall be non-transferable and non-assignable by the Grantee other than upon
death as provided in Section 7.5 below and that during the lifetime of the
Grantee such Option and Stock Appreciation Rights may be exercised only by the
Grantee or such Grantee's legal representative.

         7.3     EXERCISE OF OPTIONS:  Each Option Agreement shall set forth
the period during which it may be exercised; provided, however, subject to
Article V, Incentive Stock Options granted pursuant to this Plan shall expire
not more than 10 years from the date that the Incentive Stock Option is
granted.

         7.4     EXERCISE OF OPTIONS UPON TERMINATION OF EMPLOYMENT:  Except as
otherwise specifically determined by the Board, the Option Agreement shall
provide that when a Grantee ceases to be an Employee, any unexercised vested
Option or any non-vested Option granted to that Grantee shall terminate
immediately; provided, however, that (a) if the cessation of employment is due
to death, any unexercised vested Option (but not any non-vested Option) may be
exercised in the manner hereinafter described in Section 7.5 below or (b) if
the cessation of employment is for any reason other than death, any unexercised
vested Option (but not any non-vested Option) may be exercised until three
months after cessation (or 12 months if the Grantee is disabled within the
meaning of Section 105(d)(4) of the Code), but not later than the date that
such Option would otherwise terminate under the Plan.

         In the event that the Grantee dies within such time period, any
unexercised vested Option which has not terminated prior to death may be
exercised in the manner hereinafter provided in Section 7.5 below.

         A transfer of employment from the Company to a Subsidiary or vice
versa or between two such Subsidiaries shall not be deemed a termination of
employment.

         7.5     EXERCISE OF OPTIONS UPON DEATH:  Except as otherwise
determined by the Board, the Option Agreement shall provide that upon the death
of a Grantee while still an Employee, or within three months after the
cessation of employment for any reason other than death (or 12 months in the
case of a disabled Grantee), any unexercised vested Option (but not any
non-vested Option) may be exercised by the Grantee's estate, the person
designated in the Grantee's last will and testament or his or her heirs at law
before the date that such Option would otherwise terminate; provided, however,
that an Option may be exercised only if and to the extent that the Grantee was
entitled to exercise it as of the date of death.

         7.6     METHOD OF EXERCISE OF OPTIONS:  Each Option Agreement shall
provide that Options shall be exercised by delivering a written notice of
exercise to the Company.  Each such notice shall state the number of shares of
Common Stock in respect of which the Option is being





                                      -6-
<PAGE>   7
exercised and shall be signed by the person (or persons) exercising the Option
and, in the event the Option is being exercised by any person other than the
Grantee, shall be accompanied by proof, satisfactory to counsel for the
Company, of the right of such person to exercise the Option.  A certified or
cashier's check in full payment of the purchase price for the number of shares
of Common Stock specified in the notice must accompany such notice.  In
addition, except to the extent provided at Section 7.9(h) below, in the event
that the Option being exercised is a Non-Statutory Stock Option, the notice
must be accompanied by a certified or cashier's check in full payment of the
aggregate amount of any federal, state or local withholding taxes determined by
the Company (the "Withholding Taxes"), if any, attributable to the transfer of
stock pursuant to the exercise of the Option.

         7.7     FORFEITURE:  The Option Agreement may provide for such
conditions on the right of exercise as the Board, in its sole discretion, deems
appropriate, which conditions may, without limitation, include conditions based
upon completion of a further period of continued employment, or the performance
of the Company, a subsidiary, a division thereof, or the Grantee.  Without
limiting the foregoing, an Option Agreement may provide that the Board, in its
sole discretion, may terminate in whole or in part any portion of the Option
which has not yet become vested if it determines that the Grantee is not
satisfactorily performing his or her duties as an Employee.

         7.8     CHARACTER OF OPTION GRANTED:  Each Option Agreement shall
specifically provide whether the Option granted thereby is an Incentive Stock
Option or a Non-Statutory Stock Option: provided, however, that an Option shall
be a Non-Statutory Stock Option only if it fails to qualify as an "incentive
stock option" as defined in Section 422(b) of the Code.

         7.9     PROVISIONS RELATING  TO STOCK APPRECIATION RIGHTS:  In the
event that the Board grants Stock Appreciation Rights to the Grantee pursuant
to Section 4.2(i) hereof, then in addition to the provisions described above,
the Option Agreement shall include the following provisions:

                 (a)      No Stock Appreciation Right shall be exercisable
                 during the first six months of its term, except in the event
                 that the physical disability of the holder thereof occurs
                 prior to the expiration of such six-month period.

                 (b)      No Stock Appreciation Right shall at any time be
                 exercisable with respect to the Reference Option or any
                 portion thereof unless (i) such Option or such portion shall
                 itself be exercisable at that time, and (ii) such other
                 conditions, if any, imposed by the Board shall have been
                 satisfied.

                 (c)      No Stock Appreciation Right granted to a Grantee
                 shall be transferable by him other than by will or the laws of
                 descent and distribution, and such right shall be exercisable,
                 during his lifetime, only by the Grantee or his legal
                 representative.





                                      -7-
<PAGE>   8
                 (d)      The Stock Appreciation Right shall be transferable
                 only when the Reference Option is transferable, and under the
                 same conditions.

                 (e)      The Stock Appreciation Right shall expire no later
                 than the time at which the Reference Option expires.

                 (f)      The Stock Appreciation Right may be exercised only at
                 such time as the market price of the stock subject to the
                 Reference Option exceeds the exercise price of such Reference
                 Option.

                 (g)      Any exercise by an officer of the Company (as defined
                 for this purpose by the regulations of the Securities and
                 Exchange Commission) of a Stock Appreciation Right shall be
                 made during the period beginning in the third business day
                 following the date of release for publication of quarterly and
                 annual summary statements of sales and earnings of the Company
                 and its subsidiaries, and ending on the twelfth business day
                 following such date.

                 (h)      Upon the exercise of a Stock Appreciation Right, the
                 Company shall withhold from the cash to be distributed to the
                 Grantee an amount equal to the aggregate amount of the
                 Withholding Taxes, if any, attributable to the exercise of
                 such Stock Appreciation Right and may, in its sole discretion,
                 also withhold an amount equal to the Withholding Taxes
                 attributable to the exercise of any Non-Statutory Stock Option
                 exercised by the Grantee at the same time of the exercise of
                 such Stock Appreciation Right, in which case such Grantee
                 shall not be required to tender payment of such Withholding
                 Taxes in order to exercise such Non-Statutory Stock Option.

         7.10    ADDITIONAL TERMS:  The Option Agreement may include such other
terms and conditions, not inconsistent with this Plan, as the Board in its sole
discretion shall determine.


                                  ARTICLE VIII

                           STOCK APPRECIATION RIGHTS

         8.1     GRANT:  The Board may grant Stock Appreciation Rights to any
Grantee at any time and from time to time during the term of the Option to
which it relates.  Each Stock Appreciation Right shall be subject to terms and
conditions which are at least as restrictive as those which govern the Option
to which it relates and may, in the sole discretion of the Board, be subject to
additional restrictions.

         8.2     SHARE REDUCTION:  Upon the exercise of any Stock Appreciation
Right, the number of shares of Common Stock which were available for purchase
under the Reference Option shall be reduced by a corresponding number and the
Reference Option shall be cancelled





                                      -8-
<PAGE>   9
to that extent.  Notwithstanding anything contained in Section 3.3 hereof to
the contrary, for purposes of determining the number of shares of Common Stock
available for purchase under the Plan, in the event and to the extent that a
Reference Option is cancelled as a result of the exercise of a Stock
Appreciation Right, such Reference Option shall be deemed to have been
exercised and the shares which would have been issued had the Reference Option
been exercised shall not be available for future grants under the Plan.

         8.3     USE:  Stock Appreciation Rights shall be used solely as a
device for the measurement and determination of the amount to be paid to the
Grantee.  Stock Appreciation Rights shall not constitute or be treated as
property or as a trust fund of any kind.  All amounts which are at any time
attributable to the Stock Appreciation Rights shall be and remain the sole
property of the Company and the Grantee's rights hereunder are limited to the
right to receive cash as provided in this Plan.


                                   ARTICLE IX

                              EXERCISE OF OPTIONS

         For all purposes the date of exercise of the Option shall be the date
on which the notice specified in Section 7.6 shall have been delivered to the
Company, but the exercise of that Option shall not be effective until the
person (or persons) exercising the Option has complied with all the provisions
of the Option Agreement governing the exercise of the Option.  The Company
shall promptly deliver certificates for the shares of the Common Stock subject
to the Option, provided that the Company shall not be required, upon the
exercise of any Option, to issue or deliver any shares of Common Stock prior to
the completion of such registration or other qualification of the Common Stock
under any state or federal law, rule or regulation as the Company shall
determine to be necessary and in such event the date of delivery shall be
extended for the period necessary and further provided, that in the event that
the amount of withholding taxes attributable to the transfer of the Common
Stock cannot be determined on the date on which the Option is exercised,
whether due to the fact that the Common Stock transferred upon such exercise is
"non-transferable" by him or her, "subject to a substantial risk of forfeiture"
(as those terms are defined in Section 83 of the Code) or otherwise, the
Company shall issue and transfer the shares to the person (or persons)
exercising such Option but may require such person (or persons) to pledge the
shares to the Company as security for the payment of the applicable withholding
taxes until such time as such payment is made.  No one shall be or be deemed to
be the holders of any Common Stock subject to an Option unless and until
certificates for the shares of such Common Stock are issued to that person.

                           EFFECT OF CERTAIN CHANGES

         10.1    ADJUSTMENTS:  If there is any change in the number of shares
of Common Stock through the declaration of stock dividends or through a
recapitalization which results in stock splits or reverse stock splits, the
number of shares of Common Stock available for Options as well as the number of
such shares covered by outstanding Options, and the price per share of such
Options, shall be proportionately adjusted by the Board to reflect any increase
or decrease in the number of issued shares of Common Stock; provided, however,
that any fractional shares resulting from such adjustment shall be eliminated.

         10.2    PAR VALUE:  In the event of a change in the Common Stock of
the Company, as presently constituted, which is limited to a change of all of
its authorized shares with par value into the same number of shares with a
different par value or without par value, the shares resulting from any such
change shall be deemed to be the Common Stock within the meaning of the Plan.

         10.3    MAJOR TRANSACTIONS:  In the event of any future merger,
consolidation, liquidation, or other reorganization of the Company, or any
transaction which would cause the Common Stock, if at sometime hereafter it
shall be publicly traded, to cease to be publicly traded, the Board may provide
for all outstanding options to be either amended to apply to an appropriate
number of securities of the entity resulting from such transaction (and such
entity shall thereafter be considered the Company), or for all such Options to
be cancelled immediately prior to such transaction, on such terms as it deems
equitable: provided, however, no vested Option shall be cancelled unless the
Grantee is given an opportunity to exercise such Option during a period of not
fewer than 30 days prior to such transaction.

         10.4    BOARD DETERMINATION:  To the extent that the foregoing
adjustments relate to stock or securities of the Company, such adjustments
shall be made by the Board, whose determination in that respect shall be final,
binding and conclusive.

         10.5    EFFECT:  Except as hereinbefore expressly provided in this
Article X, the Grantee shall have no rights by reason of any subdivision or
consolidation of shares of stock of any class or the payment of any stock
dividend or any other increase or decrease in the number of shares of stock of
any class or by reason of any dissolution, liquidation, merger, or
consolidation or spin-off of assets or stock of another corporation, and any
issue by the Company of shares of stock of any class, or securities convertible
into shares of stock of any class, shall not affect, and no adjustment by
reason thereof shall be made with respect to the number or price of shares of
Common Stock subject to the Option.  The grant of an Option shall not affect in
any way the right or power of the Company to make adjustments,
reclassifications, reorganizations or changes of its capital or business
structures or to merge or to consolidate or to dissolve, liquidate or sell or
transfer all or part of its business or assets.

                           AMENDMENT AND TERMINATION

         The Board shall have the right to amend or suspend, or terminate the
Plan at any time, provided that, to the extent required by law, unless first
approved by the stockholders of the Company, no amendment shall be made to the
Plan (except to conform the Plan and the Option Agreements thereunder to
changes in the Code or governing law) which (a) materially modifies the
eligibility requirements of Article V, (b) increases the total number of shares
of Common Stock which may be issued under the Plan, (c) changes the option
price specified in Article VII, or (d) changes the term of the Plan as set
forth in Article XIV.  No amendment to the Plan shall be made by the Board that
materially changes the terms of the Plan so as to impair or adversely alter the
rights of a Grantee or other Option holder without such person's consent.


                                  ARTICLE XII

                              APPLICATION OF FUNDS

         Any proceeds received by the Company as a result of the exercise of
Options granted under the Plan may be used for any valid corporate purpose.


                                  ARTICLE XIII

                                     NOTICE

         Any notice to the Company required under this Plan shall be in writing
and shall either be delivered in person or sent by registered or certified
mail, return receipt requested, postage prepaid, to the Company at its
principal executive offices, Attention:  Benefits Plan Administrator.


                                  ARTICLE XIV

                                  TERM OF PLAN

         The Plan shall terminate 10 years from the date upon which it is
approved by the stockholders of the Company or on such earlier date as may be
determined by the Board.  In any event, termination shall be deemed to be
effective as of the close of business on the day of termination.  No Options
may be granted after such termination.  Termination of the Plan, however, shall
not affect the rights of Grantees under Options previously granted to them, and
all unexpired Options shall continue in force and operation after termination
of the Plan until they lapse or terminate by their own terms and conditions.

would own stock and/or hold outstanding options to purchase stock possessing
five percent (5%) or more of the total combined voting power or value of all

Participant may change the rate or amount of his or her payroll deductions
before the Enrollment Date for any Offering Period by completing or filing with
the Company a payroll authorization form changing the rate or amount of payroll
deductions.  The change in rate or amount shall be effective with the first
full payroll period to occur during such Offering Period.  Subject to the
limitations of Section 6(a), a Participant's payroll authorization form shall
remain in effect for successive Offering Periods unless revised as provided
herein or terminated as provided in Section 10.

                 (d)      Notwithstanding the foregoing, to the extent
necessary to comply with Section 423(b)(3) of the Code and Section 3(b) herein,
a Participant's payroll deductions may be decreased or ended, during any
calendar year in which the total of accumulated payroll deductions equal Twenty
Thousand Dollars ($20,000).  Payroll deductions shall recommence at the rate
provided in such Participant's payroll deduction authorization form at the
beginning of the first Offering Period which is scheduled to end in the
following calendar year, unless terminated by the Participant as provided in
Section 10.

         7.      GRANT OF OPTION.  On the Enrollment Date of each Offering
Period, each eligible Employee participating in such Offering Period shall be
granted an Option to purchase on each Exercise Date during such Offering Period
up to a number of shares of Common Stock determined by dividing such Employee's
payroll deductions accumulated prior to such Exercise Date and retained in the
Participant's account as of the Exercise Date by eighty-five percent (85%) of
the Fair Market Value of a share of the Common Stock on the Exercise Date;
provided that in no event shall an Employee be permitted to purchase during
each Offering Period more than a number of shares determined by dividing
$20,000 by the fair market value of a share of the Common Stock on the
Enrollment Date, and provided further that such purchase shall be subject to
the limitations set forth in Section 3(b) and 12 hereof.  Exercise of the
Option shall occur as provided in Section 8, unless the Participant has
withdrawn pursuant to Section 10, and shall expire on the last day of the
Offering Period.

         8.      EXERCISE OF OPTION.  The Company will give each Participant
notice of each Exercise Date thirty (30) days prior to such Exercise Date.
Unless a Participant withdraws from the Plan as provided in Section 10 his or
her Option for the purchase of shares will be exercised automatically on the
last working day of the Offering Period, and the maximum number of full shares
subject to Option shall be purchased for such Participant at the applicable
Option price with the accumulated payroll deductions in his or her account.
Any amount remaining in the Participant's account after an Exercise Date shall
be held in the account until the next Exercise Date of the Offering Period,
unless the Offering Period has been oversubscribed or has terminated with such
Exercise Date, in which case such amount shall be refunded to the Participant.
During a Participant's lifetime, a Participant's Option to purchase shares
hereunder is exercisable only by him or her.

         9.      DELIVERY.  As promptly as practicable after each Exercise Date
on which a purchase of shares occurs, the Company shall arrange the delivery to
each Participant, as appropriate, of a certificate representing the Common
Stock purchased upon exercise of his or her Option.

         10.     WITHDRAWAL; TERMINATION OF EMPLOYMENT.

                 (a)      A Participant may withdraw all but not less than all
the payroll deductions credited to his or her account and not yet used to
exercise his or her Option under the Plan at any time by giving written notice
to the Company.  All of the Participant's payroll deductions credited to his or
her account will be paid to such Participant promptly after receipt of notice





                                      -4-
<PAGE>   5
of withdrawal and such Participant's Option for the Offering Period will be
automatically terminated, and no further payroll deductions for the purchase of
shares will be made during the Offering Period.  If a Participant withdraws
from an Offering Period, payroll deductions will not resume at the beginning of
the succeeding Offering Period unless the Participant delivers to the Company a
new payroll deduction authorization form.

                 (b)      Upon termination of the Participant's Continuous
Status as an Employee prior to the Exercise Date for any reason, including
retirement or death, the payroll deductions credited to such Participant's
account during the Offering Period but not yet used to exercise the Option will
be returned to such Participant or, in the case of his or her death, to the
person or persons entitled thereto under Section 14, and such Participant's
Option will be automatically terminated, provided however, that, in the event
of the Participant's death, the Option may be exercised by his or her
beneficiary designated under Section 14.

                 (c)      In the event an Employee fails to remain in
Continuous Status as Employee of the Company for at least twenty (20) hours per
week during an Offering Period in which the Employee is a Participant, he or
she will be deemed to have elected to withdraw from the Plan and the payroll
deductions credited to his or her account will be returned to such Participant
and such Participant's Option terminated.

                 (d)      A Participant's withdrawal from an Offering Period
will not have any effect upon his or her eligibility to participate in any
similar plan which may hereafter be adopted by the Company or in succeeding
Offering Periods which commence after the termination of the Offering Period
from which the Participant withdraws.

         11.     INTEREST.  No interest shall accrue on the payroll deductions 
of a Participant in the Plan.

         12.     STOCK.

                 (a)      The maximum number of shares of the Company's Common
Stock which shall be made available for sale under the Plan shall be Five
Hundred Thousand (500,000) shares, subject to adjustment upon changes in
capitalization of the Company as provided in Section 18.  If on a given
Exercise Date the number of shares with respect to which Options are to be
exercised exceeds the number of shares then available under the Plan, the
Company shall make a pro rata allocation of the shares remaining available for
purchase in as uniform a manner as shall be practicable and as it shall
determine to be equitable.

                 (b)      The Participant will have no interest or voting right
in shares covered by his Option until such Option has been exercised and the
applicable shares of Common Stock are issued to him or her.

                 (c)      Shares to be delivered to a Participant under the
Plan will be registered in the name of the Participant or in the name of the
Participant and his or her spouse.

         13.     ADMINISTRATION.  The Plan shall be administered by the
Committee.  The administration, interpretation or application of the Committee
shall be final, conclusive and binding upon all Participants.  Notwithstanding
the provisions of Subsection (a) of this Section 13, in the event that Rule
16b-3 promulgated under the Securities Exchange Act of 1934, as amended (the
"Exchange Act"), or any successor provision ("Rule 16b-3") provides specific
requirements for the Administrators of plans of this type, the Plan shall only
be administered by such body and in such a manner as shall comply with the
applicable requirements of Rule 16b-3.  Unless permitted by Rule 16b-3, no
discretion concerning decisions regarding the Plan shall be afforded to any
person other than a "Non-Employee Director" as that term is defined in Rule
16b-3.

         14.     DESIGNATION OF BENEFICIARY.

                 (a)      A Participant may file a written designation of a
beneficiary who is to receive any shares and cash, if any, from the
Participant's account under the Plan if such Participant dies after an Exercise
Date on which the Option is exercised but before receiving his or her Common
Stock and cash.  In addition, a Participant may file a written designation of a
beneficiary who is to receive any cash from the Participant's account under the
Plan or exercise the Option on behalf of the Participant in the event of such
Participant's death prior to exercise of the Option.

                 (b)      Such designation of beneficiary may be changed by the
Participant at any time by written notice.  In the event of the death of a
Participant and in the absence of a beneficiary validly designated under the
Plan who is living at the time of such Participant's death, the Company shall
deliver such shares and/or cash to the executor or administrator of the estate
of the Participant, or if no such executor or administrator has been appointed
(to the knowledge of the Company), the Company, in its discretion, may deliver
such share and/or cash to the spouse or to any one or more dependents or
relatives of the Participant, or if no spouse, dependent or relative is known
to the Company, then to such other persons as the Company may designate.

         15.     TRANSFERABILITY.  Neither payroll deductions credited to a
Participant's account, nor any rights regarding an Option under the Plan may be
assigned, transferred, pledged or otherwise disposed of in any way (other than
by will, the laws of descent and distribution or as provided in Section 14
hereof) by the Participant.  Any such attempt at assignment, transfer, pledge
or other disposition shall be without effect, except that the Company may treat
such act as an election to withdraw funds from an Offering Period in accordance
with Section 10.  An Option may be exercised only by the Participant during his
or her lifetime, or, in the event of the Participant's death, by his or her
estate or the person who acquires the right to exercise such Option by bequest
or inheritance, pursuant to Sections 10(b) and 14.

         16.     USE OF FUNDS.  All payroll deductions received or held by the
Company under the Plan may be used by the Company for any corporate purpose,
and the Company shall not be obligated to segregate such payroll deductions.





                                      -6-
<PAGE>   7
         17.     REPORTS.  Individual accounts will be maintained for each
Participant in the Plan.  Statements of account will be given to participating
Employees as soon as practical following the Exercise Date, which statements
will set forth the amounts of payroll deductions, the per share purchase price,
the number of shares purchased and the remaining cash balance, if any.

         18.     ADJUSTMENTS UPON CHANGES IN CAPITALIZATION.  The aggregate
number of shares of Common Stock with respect to which Options may be granted,
the aggregate number of shares of Common Stock subject to each outstanding
Option, and the Option Price per share of each Option may be appropriately
adjusted as the Committee may determine for any increase or decrease in the
number of shares of issued Common Stock resulting from a subdivision or
consolidation of shares, whether through reorganization, recapitalization,
stock split-up, stock distribution or combination of shares, or the payment of
a share dividend or other increase or decrease in the number of such shares
outstanding effected without receipt of consideration by the Company.
Adjustments under this Section 18 shall be made according to the sole
discretion of the Committee, and its decision shall be binding and conclusive.

         19.     DISSOLUTION, MERGER AND CONSOLIDATION.  Upon the dissolution
or liquidation of the Company, or upon a merger or consolidation of the Company
in which the Company is not the surviving corporation, each Option granted
hereunder shall expire as of the effective date of such transaction; provided,
however, that the Committee shall give at least 30 days' prior written notice
of such event to each Participant during which time he or she shall have a
right to exercise his or her wholly or partially unexercised Option and,
subject to prior expiration pursuant to Section 6(b) or (c), each Option shall
be exercisable after receipt of such written notice and prior to the effective
date of such transaction.

         20.     AMENDMENT OR TERMINATION.  The Board may at any time and for
any reason terminate or amend the Plan.  Except as provided in Section 18, no
such termination can affect Options previously granted, provided that an
Offering Period may be terminated by the Board on any Exercise Date if the
Board determines that the termination of the Plan is in the best interests of
the Company and its stockholders.  Except as provided in Section 18, no
amendment or termination shall be made which would impair the rights of any
Participant under any outstanding Option, without his or her consent.  In
addition to the extent necessary to comply with Rule 16b-3 or under Section 423
of the Code (or any other successor rule or provision or any other applicable
law or regulation), the Company shall obtain stockholder approval of any Plan
amendment in such a manner and to such a degree as required.

         21.     NOTICES.  Every direction, revocation or notice authorized or
required by the Plan shall be deemed delivered (a) to the Company on the date
it is personally delivered to the Secretary of the Company at its principal
executive offices or three business days after it is sent by registered or
certified mail, postage prepaid, addressed to the Secretary at such offices;
and (b) to an optionee on the date it is personally delivered to him or her or
three business days after it is sent by registered or certified mail, postage
prepaid, addressed to him or her at the last address shown for him or her on
the records of the Company or of any Subsidiary.

         22.     STOCKHOLDER APPROVAL.  The Plan shall be subject to approval
by the stockholders of the Company.  Such stockholder approval shall be
obtained in the degree and manner required under the Delaware General
Corporation Law.

         23.     CONDITIONS UPON ISSUANCE OF SHARES.  Shares shall not be
issued with respect to an Option unless the exercise of such Option and the
issuance and delivery of such shares complies with all applicable provisions of
law, domestic or foreign, including, without limitation, the Securities Act of
1933, as amended, the Exchange Act, the rules and regulations promulgated
thereunder, and the requirements of any stock exchange upon which the shares
may then be listed, and shall be further subject to the approval of counsel for
the Company with respect to such compliance.

         As a condition to the exercise of an Option, the Company may require
the person exercising such Option to represent and warrant at the time of any
such exercise that the shares are being purchased only for investment and
without any present intention to sell or distribute such shares if, in the
opinion of counsel for the Company, such a representation is required by any of
the aforementioned applicable provisions of law.

         24.     TERM OF PLAN.  The Plan shall become effective upon its
approval by the stockholders of the Company as described in Section 22.  It
shall continue in effect for a term of ten (10) years unless sooner terminated
under Section 20.

         25.     MISCELLANEOUS.

                 (a)      Legal and Other Requirements.  The obligations of the
Company to sell and deliver Common Stock under the Plan shall be subject to all
applicable laws, regulations, rules and approvals, including, but not by way of
limitation, the effectiveness of a registration statement under the Securities
Act of 1933.  Certificates for shares of Common Stock issued hereunder may be
legended as the Committee shall deem appropriate.

                 (b)      Withholding Taxes.  Upon the exercise of any Option
under the Plan, the Company shall have the right to require the Participant to
remit to the Company an amount sufficient to satisfy all federal, state and
local withholding tax requirements prior to the delivery of any certificate or
certificates for shares of Common Stock.

                 (c)      Right to Terminate Employment.  Nothing in the Plan
or any agreement entered into pursuant to the Plan shall confer upon any
employee the right to continue in the employment of the Company or any
Subsidiary or affect any right which the Company or any Subsidiary may have to
terminate the employment of such employee.

                 (d)      Applicable Law.  All questions pertaining to the
validity, construction and administration of the Plan and Options granted
hereunder shall be determined in conformity with the laws of the State of
Delaware, to the extent not inconsistent with Section 423 of the Code and
regulations thereunder.

                 (e)      Elimination of Fractional Shares.  If under any
provision of the Plan which requires a computation of the number of shares of
Common Stock subject to an Option, the number so computed is not a whole number
of shares of Common Stock, such number of shares of Common Stock shall be
rounded down to the next whole number and remaining paid in cash.

shall deliver to Landlord for its approval Final Architectural Plans for such
Additional Work at or before the time Tenant is required pursuant to Paragraph

                estimates) of the Additional Work shall be paid to Contractor
                upon substantial completion


                                      D-3
<PAGE>   11
                of such Additional Work, but in no case later than Possession
                Date by Tenant,

and, provided Tenant has made all payments and borne all costs when required
herein, Tenant agrees to cause the Additional Work to be performed by Tenant's
contractors.  All sums due hereunder from Tenant shall be deemed to be Rent for
any and all purposes of the Lease.

          If Tenant requires Additional Work pursuant to and in accordance with
the foregoing provisions of this Paragraph 3.00, the alterations and
improvements to be made to the Leased Premises prior to the Commencement Date

shall not commence until Tenant's Contractor shall have substantially completed
all the work on February 1, 1996, whichever is earlier, provided, however, that
if Landlord shall be delayed in substantially completing such Work as a result
of any one or more of the following:

        4.01    Tenant's or the Architect's failure to devote the time or
                furnish the information required under Paragraph 2.00 hereof in
                connection with the Final Architectural Plans for the Work or
                Tenant's failure to furnish the Final Architectural Plans for
                the Additional Work, or revisions thereto, as required hereby,
                or

        4.02    Tenant's failure to approve cost estimates for the Additional
                Work within the time period specified in Paragraph 3.00 hereof,
                or


        4.03    Tenant's changes in the Work, in the Final Architectural Plans
                relating thereto, or in the Architectural Plans for the
                Additional Work (notwithstanding Landlord's approval of any such
                changes);

then, and in any such event, Tenant's obligation to commence the payment of Rent
under the Lease on the Commencement Date shall not be affected or deferred on
account of such delay.

5.00 ACCESS BY TENANT PRIOR TO THE COMMENCEMENT DATE.  Landlord, at Landlord's

<PAGE>   12
that Tenant may make the Leased Premises ready for Tenant's use and occupancy
("Specified Work"). If Landlord permits such entry prior to the commencement
Date, such permission shall constitute a license only and not a lease and such
license shall be conditioned upon; (a) Tenant working in harmony and not
interfering with Landlord and Landlord's agents, contractors, workmen,
mechanics and suppliers in doing the Work, Specified Work or Additional Work,
if any, or Landlord's work in the Building or with other Tenants and occupants
of the Building; (b) Tenant obtaining in advance Landlord's approval of the
contractors proposed to be used by Tenant obtaining in advance Landlord's
approval of the contractors proposed to be used by Tenant and depositing with
Landlord in advance of any work (i) security reasonably satisfactory to
Landlord for the completion thereof, (ii) general contractor's affidavit for
proposed work and waiver of lien rights from general contractor, all
subcontractors and suppliers of material; (c) Tenant or its contractors
furnishing Landlord with such insurance and other security as Landlord may
require against liabilities which may arise out of such entry. Landlord shall
have the right to withdraw such license for cause upon twenty-four (24) hours'
written notice to Tenant. Tenant agrees that Landlord shall not be liable in
any way for any injury, loss or damage which may occur to any of Tenant's
property placed or installations made in the Leased Premises prior to the
Commencement Date of the Lease, the same being at Tenant's sole risk and Tenant
agrees to protect, defend, indemnify and save harmless Landlord, manager, and
Landlord's agents from all liabilities, costs, damages, fees and expenses
arising out of or connected with the activities of Tenant or its agents,
contractors, suppliers or workmen in or about the Leased Premises, the
Building or the Property. Tenant further agrees that any entry and occupation
permitted under this paragraph shall be governed by the terms of the lease.

6.00 MISCELLANEOUS.

     6.01  Except to the extent otherwise indicated herein, the initially
           capitalized terms used in this Tenant Improvement Work Agreement
           shall have the meanings assigned to them in the Lease.

     6.02  The terms and provisions of this Tenant Improvement Work Agreement
           are intended to supplement and are specifically subject to all the
           terms and provisions of the Lease.  In addition, to complying with
           the terms and conditions of the Lease, Tenant agrees that it shall
           comply with the Rules and Regulations set forth on Exhibit D-2.

     6.03  This Tenant Improvement Work Agreement may not be amended or modified
           other than by supplemental written agreement executed by authorized
           representations of the parties hereto.

     6.04  All payments due from Tenant pursuant to this Tenant Improvement Work
           Agreement shall be deemed Additional Rent.

         1.00    LEASE AGREEMENT.  Landlord leases to Tenant and Tenant leases
from Landlord the Leased Premises for the Term, and covenant and agree pursuant
to the terms and conditions as set forth in this Lease.

         2.00    RENT.

         2.01    KINDS OF RENT.  Rent and all other payments due from Tenant
shall be made to Manager or to such other persons or at such places as Landlord
may direct from time to time by written notice to Tenant, in lawful money of
the United States of America.  Tenant agrees to pay the aggregate of the
following each of which, unless otherwise noted shall be due separately without
deduction or offset against each other or other amounts due hereunder.  Any
decrease in Operating Costs, Taxes or other amounts below those set forth in
the Base Costs shall not be recoverable by nor credited to Tenant.

                 (a)      BASE RENT.  Base Rent to be paid in monthly
         installments in advance on or before the first day of each calendar
         month during the Term without demand and without any set-off or
         deduction whatsoever in the amount set forth in the Schedule.  Tenant
         shall pay an amount equal to one full monthly installment of Base Rent
         at the time of execution of the Lease, which amount shall be credited
         to the first full monthly installment of Base Rent payable hereunder.
         If the Term commences other than on the first day of the month or ends
         other than on the last day of the month, the Base Rent for such months
         shall be prorated and the prorated Base Rent for the portion of the
         month in which the Term commences shall also be paid at the time of
         execution of the Lease.  Unpaid Base Rent and other amounts due under
         this Lease shall bear interest at the rates provided for in the Lease
         from the date due until paid.

                 (b)      OPERATING ADJUSTMENT RENT.  Operating Adjustment Rent
         to be paid monthly in advance in an estimated amount as adjusted by
         Landlord from time to time to cover Tenant's Operating Proportionate
         Share of the increase in any Comparison Year in Operating Costs for
         said Comparison Year over Base Costs.

                 (c)      TAX ADJUSTMENT RENT.  Tax Adjustment Rent to be paid
         monthly in advance in an estimated amount as adjusted by Landlord from
         time to time to cover the Tenant's Tax Proportionate Share of the
         increase in any Comparison Year in Taxes for said Comparison Year over
         Base Taxes.

                 (d)      INDEX RENT.  [INTENTIONALLY DELETED]

                 (e)      ADDITIONAL RENT.  Additional Rent consisting of all
         of the sums, liabilities, obligations and other amounts (excepting
         Base Rent, Operating Adjustment Rent and Tax Adjustment Rent) which
         Tenant is required to pay or discharge pursuant to this Lease, all as
         hereafter provided.  Additional Rent shall be due and payable within
         ten (10) days after statement from Landlord.  Without limitation on
         other obligations of Tenant which shall survive the expiration of the
         Term, the obligations of Tenant to pay the Additional Rent provided
         for in this Section 2.00 shall survive the expiration of the Term.

         2.02    PAYMENT OF ADJUSTMENT RENT.

                 (a)      PAYMENT OF ESTIMATED OPERATING ADJUSTMENT RENT AND
         TAX ADJUSTMENT RENT.  Landlord shall estimate the Operating Costs and
         Taxes each Year.  Such estimates may be





                                     - 2 -
<PAGE>   25
         revised by Landlord one or more times during the Year as necessary to
         make such estimates more accurate.

                 If Landlord's estimate of Operating Costs in any Year reflects
         an increase in the Operating Costs beyond the Base Costs set forth in
         the Schedule, upon notice from Landlord, Tenant shall pay Landlord one
         twelfth (1/12th) of Tenant's Operating Proportionate Share of such
         estimated increase in such costs for each month in such Year on the
         first day of each calendar month during the Year.  If at one or more
         times during such Year Landlord revises its estimate of Operating
         Costs for such Year, Landlord may notify Tenant of such revised
         estimate and of the increase or decrease in Tenant's Operating
         Proportionate share of such revised estimate payable monthly
         thereafter during such Year necessary to cause the total monthly
         payments during such Year to equal Landlord's then current estimate of
         the Tenant's Operating Proportionate Share for such Year. Tenant shall
         thereafter pay such revised monthly payment amount on the first day of
         each calendar month thereafter during such Year.

                 If Landlord's estimate of Taxes in any Year reflects an
         increase in the Taxes beyond the Base Taxes set forth in the Schedule,
         upon notice from Landlord, Tenant shall pay Landlord one-twelfth
         (1/12th) of Tenant's Tax Proportionate Share of such estimated
         increase in such Taxes for each month in such Year on the first day of
         each calendar month during the Year. If at one or more times during
         such Year Landlord revises its estimate of Taxes for such Year,
         Landlord may notify Tenant of such revised estimate and of the
         increase or decrease in Tenant's Tax Proportionate Share thereafter
         payable during such Year necessary to cause the total monthly payments
         during such Year to equal Landlord's then current estimate of the
         Tenant's Tax Proportionate Share for such Year.  Tenant shall
         thereafter pay such revised monthly payment amount on the first day of
         each calendar month thereafter during such Year.

                 (b)      CORRECTION OF OPERATING ADJUSTMENT RENT.  Each Year
         Landlord shall deliver to Tenant a report setting forth the actual
         Operating Costs for the preceding Year and a statement of the amount
         of Operating Adjustment Rent that Tenant has paid and is payable for
         that preceding Year.  Within thirty (30) days after receipt of such
         report, Tenant shall pay to Landlord the amount of Operating
         Adjustment Rent due for the preceding Year (or a portion thereof if
         the Lease was not in effect for the entire Year) minus any estimated
         payments made by Tenant or credits due Tenant for such previous Year.
         If Tenant's estimated payments of Operating Adjustment Rent exceed the
         amount due Landlord for the Comparison Year in question, Landlord, at
         its option, shall either refund any such amount to Tenant or apply any
         such amount as a credit against Tenant's other obligations under this
         Lease.

                 (c)      CORRECTION OF TAX ADJUSTMENT RENT.  Each Year
         Landlord shall deliver to Tenant a report setting forth the actual
         Taxes for the preceding Year and a statement of the amount of Tax
         Adjustment Rent that Tenant has paid and is payable for that preceding
         Year.  Within thirty (30) days after receipt of such report, Tenant
         shall pay to Landlord the amount of Tax Adjustment Rent due for the
         preceding Year (or a portion thereof if the Lease was not in effect
         for the entire Year) minus any estimated payments made by Tenant or
         credits due Tenant for such previous Year.  If Tenant's estimated
         payments of Tax Adjustment Rent exceed the amount due Landlord for the
         Comparison Year in question, Landlord, at its option, shall either
         refund any such amount to Tenant or apply any such amount as a credit
         against Tenant's other obligations under this Lease.

         2.03    RULES OF INTERPRETATION AND COMPUTATION OF BASE RENT AND RENT
                 ADJUSTMENTS:

                 (a)      COMMENCEMENT AND END.  If this Lease commences or
         ends on other than the first day or last day of a month, respectively,
         the Rent for the month in which this Lease so begins or ends shall be
         prorated.  The Rent due for any such month shall be a sum equal to the
         total of the Base Rent, Operating Adjustment Rent and Tax Adjustment
         Rent payable for a full month multiplied by a fraction, the numerator
         of which is the number of days in the month in which the Lease was in
         effect and the denominator of which is the total number of days in the
         month.

                 (b)      RENT WITHOUT DEDUCTION.  All Rent shall be paid to
         Manager without deduction or offset at the office of Manager at the
         Property or to such other person or place as Landlord may from time to
         time designate in writing.  The covenants to pay Rent shall be
         independent of any other covenant.

                 (c)      NO REFUND IF DEFAULT.  If Tenant is in default of any
         of its obligations under this Lease, Tenant shall not be entitled to
         any refund of any sum which may otherwise be due it by application of
         any provision of this Lease until any and all Tenant's defaults under
         the Lease are cured by Tenant.

                 (d)      CHANGES TO PROPORTIONATE SHARE.  If any changes are
         made to this Lease or to the Property changing the number of Rentable
         Square Feet contained in the Leased Premises or significantly changing
         the number of Rentable Square Feet in the Property, Tenant's Operating
         Proportionate Share and Tenant's Tax Proportionate Share may be
         appropriately adjusted.

                 (e)      CERTIFICATION OF OPERATING COSTS AND TAXES.  The
         annual statement of actual Operating Costs and Taxes to be furnished
         by Landlord under this Section shall be prepared in accordance with
         generally accepted accounting principles.  Failure by Landlord to
         submit such a statement shall not prejudice Landlord's right to
         collect any Rent or other sum that is due.  In the event of any
         dispute as to any Operating Adjustment Rent or Tax Adjustment Rent,
         Tenant shall have the right to inspect Landlord's accounting records
         relative to Operating Costs and Taxes at Landlord's accounting office
         during normal business hours at any time within sixty (60) days
         following the furnishing by Landlord to Tenant of such statement.
         Unless Tenant shall take written exception to any item in any such
         statement within such sixty (60) day period, such statement shall be
         considered as final and accepted by Tenant.  If Tenant makes such
         timely written exception, a certification as to the proper amount of
         Operating Adjustment Rent and Tax Adjustment Rent shall be made by
         Landlord's independent certified public accountant which shall be
         final and conclusive.  Tenant agrees to pay the cost of such
         certification unless it is determined that Landlord's original
         determination of Taxes and Operating Costs was in error by more than
         three percent (3%).

                 (f)      SURVIVAL OF RENT OBLIGATIONS.  In the event of the
         termination of this Lease by expiration of the Term or for any other
         cause or reason whatsoever prior to the determination of Operating
         Adjustment Rent, Tax Adjustment Rent and Additional Rent, Tenant's
         agreement to pay any such sums shall survive termination of the Lease.
         Tenant shall pay any amount due to Landlord within fifteen (15) days
         after being billed therefor.  In the event of the termination of this
         Lease by expiration of the Term or for any other cause or reason
         whatsoever, except default by Tenant of any of the terms or provisions
         of this Lease, prior to the determination of

         forth, Landlord's agreement to refund any excess Tenant's estimates
         paid by Tenant over the Operating Adjustment Rent or Tax Adjustment
         Rent up to the time of termination shall survive termination of the
         Lease and Landlord shall pay the amount due to Tenant within fifteen
         (15) days of Landlord's determination of such amount.

                 (g)      BASE RENT LIMITATION ON ADJUSTMENT.  No adjustment to
         Operating Adjustment Rent or Tax Adjustment Rent shall result in the
         payment by Tenant in any Comparison Year of less than the Base Rent
         shown on the Schedule.  All amounts owed to Landlord hereunder, for
         which the date of payment is not expressly fixed herein, shall be paid
         within thirty (30) days from the date Landlord renders statements of
         account therefor and shall bear interest at the rate provided in
         Section 15.06 from the date due until paid.

                 (h)      LATE PAYMENTS.  Any payment of Rent which is not
         received within five (5) days after it is due will be subject to a
         late charge equal to five percent (5%) of the unpaid payment, or
         $100.00, whichever is greater.  This amount is in compensation of
         Landlord's additional cost of processing late payments.

                 (i)      APPLICATION OF PAYMENTS.  Landlord shall have the
         right to apply payments received from Tenant pursuant to this Lease
         (regardless of Tenant's designation of such payments) to satisfy any
         obligations of Tenant hereunder, in such order and amounts as Landlord
         in its sole discretion may elect.

         3.00    SECURITY DEPOSIT.     (See Schedule)

         3.01    USE AND APPLICATION.  As additional security for the full and
prompt performance of its obligations hereunder, Tenant has concurrently with
the execution of this Lease paid to Landlord the amount set forth on the
Schedule.  Said Security Deposit need not be segregated and may be applied by
Landlord for the purpose of payment of Rent or other sums due from Tenant,
curing any default or defaults of Tenant hereunder, or for the payment of any
sum which Landlord may be required to expend by reason of Tenant's default or
to pay to Landlord any loss or damages Landlord may suffer by reason of
Tenant's default.  Tenant shall replenish said deposit in full within five (5)
days after written demand therefor by paying to Landlord on demand the amount
so applied.  Tenant's failure to do so shall be a material breach of this
Lease.  Application of the Security Deposit, or any portion thereof, by
Landlord shall not prevent Landlord from exercising any other right or remedy
provided by this Lease or by law (it being intended that Landlord shall not
first be required to proceed against the Security Deposit) and shall not
operate as a limitation on any recovery to which Landlord may otherwise be
entitled.  Landlord shall not pay any interest on said deposit except as
required by law.  After the termination of this Lease and the vacation of the
Leased Premises by Tenant, any portion of said Security Deposit then being held
by Landlord which Landlord is not entitled to apply as aforesaid shall be
returned to Tenant.  In the absence of evidence satisfactory to Landlord of any
permitted assignment of the right to receive the Security Deposit or the
remaining balance thereof, Landlord may return the same to the original Tenant,
regardless of one or more assignments of Tenant's interest in this Lease or the
Security Deposit.  In such event Landlord shall be completely relieved of
liability under Section 3.00 or otherwise with respect to the Security Deposit.
Said Security Deposit shall not be deemed an advance payment of Rent, a payment
of Rent for the last month of the Term, a payment of liquidated damages, or a
measure of Landlord's damages for any default hereunder by Tenant.  The use,
application or intention of the Security Deposit, or any portion thereof, by
Landlord shall not prevent Landlord from exercising any other right or remedy
provided by this Lease or by





                                     - 5 -
<PAGE>   28
law, it being intended that Landlord shall not first be required to proceed
against the Security Deposit, and shall not operate as a limitation on any
recovery to which Landlord may otherwise be entitled.

         3.02    TRANSFER OF LANDLORD'S INTEREST.  Tenant acknowledges that
Landlord has the right to transfer or mortgage its interests in the Property,
and this Lease, or any of them, and Tenant agrees that in the event of any such
transfer, Landlord shall have the right to transfer all its interests with
respect to the Property, including but not limited to, the Security Deposit to
the transferee.  Upon the delivery by Landlord to such transferee of said
interests, including the Security Deposit, Landlord shall be released from all
liability or obligation for the return of, or otherwise with respect to said
interests, or the Security Deposit or interest thereon, and Tenant, for itself
and its successors and assigns, agrees to look solely to such transferee
thereafter, including, but not limited to the return of the Security Deposit
and interest thereon, if any.

         4.00    USE OF LEASED PREMISES.  The Leased Premises shall be occupied
and used by Tenant only for executive and general administrative offices
directly pertaining to the operation of Tenant's business for the use set forth
on the Schedule, and for no other purpose.  Without limiting the generality of
the foregoing, no use shall be made of the Leased Premises nor acts done which
will increase the existing rate of insurance upon the Property or cause a
cancellation of any insurance policy covering the Property or any part thereof.
Tenant shall not permit to be kept, used or sold in or about the Leased
Premises any article which may be prohibited by Landlord's insurance policies.
Tenant will not in any way obstruct or interfere with the rights of other
tenants or injure or annoy them.  Tenant shall not occupy or use the Leased
Premises or permit the Leased Premises to be occupied or used for any purpose,
act or thing which is in violation of any public law, ordinance or governmental
regulation which is now in effect or may be enacted after the date of this
Lease, or which may be dangerous to persons or property.

         5.00    BUILDING SERVICES.  Landlord agrees to furnish services to the
Tenant without charge except for electricity and as otherwise specifically
provided herein, as follows:

                 (a)      HEAT.  During reasonable hours (8:00 a.m. to 6:00
         p.m. Monday through Friday and 9:00 a.m. to 1:00 p.m. on Saturdays) or
         such hours as generally maintained by comparable office buildings in
         the area, of generally recognized business days, as reasonably
         determined by Landlord, for comfortable occupancy of the Leased
         Premises by Tenant.  Tenant agrees to keep and cause to be kept closed
         all windows in the Leased Premises and shall keep closed doors
         connecting the Leased Premises to public corridors and at all times to
         cooperate fully with the Landlord in the operation of the heating
         system and to abide by all reasonable regulations and requirements
         which Landlord may prescribe to permit the proper functioning and
         protection of the heating system.  Landlord reserves the right to stop
         the heating system when necessary by reason of accident or emergency
         or for repairs, alterations, replacements or improvements, which in
         the judgment of the Landlord are desirable or necessary, until said
         repairs, alterations, replacements, or improvements shall have been
         completed.  Landlord shall have no responsibility or liability for
         failure to supply heating during said period mentioned just above or
         when prevented from so doing by any cause beyond Landlord's reasonable
         control or by laws, orders or regulations of any Federal, State,
         County or Municipal authorities and Tenant shall be entitled to no
         diminution or abatement of Rent by reason of the stoppage of such
         heating for any of the aforesaid reasons whatsoever nor shall the same
         in any way affect the obligation of Tenant to perform and fulfill its
         covenants under this Lease.  Landlord agrees to make any repairs to
         the heating system promptly and with due diligence.

                 (b)      AIR CONDITIONING.  Landlord shall operate an air
         conditioning system in the Leased Premises on generally recognized
         business days during generally recognized business hours (8:00 a.m. to
         6:00 p.m. on Monday through Friday and 9:00 a.m. to 1:00 p.m. on
         Saturdays) or such hours as generally maintained by comparable office
         buildings in the area, in accordance with rules and regulations
         promulgated by Landlord, as may, in Landlord's judgement, be
         reasonably required for comfortable occupancy of the Leased Premises
         by Tenant.  Landlord's obligation for such service will be for normal
         business use and with light office machinery and shall not be
         applicable to any areas in the Leased Premises using heavy business
         machinery or other use which adversely affects the temperature or
         humidity which would otherwise be maintained in the Leased Premises.
         Tenant agrees to keep and cause to be kept closed all windows in the
         Leased Premises and shall keep closed doors connecting the Leased
         Premises to public corridors and at all times to cooperate fully with
         the Landlord in the operation of said system and to abide by all
         reasonable regulations and requirements which Landlord may prescribe
         to permit the proper functioning and protection of the air
         conditioning systems.  Landlord reserves the right to stop the air
         conditioning systems when necessary by reason of accident or emergency
         or for repairs, alterations, replacements or improvements, which in
         the judgement of the Landlord are desirable or necessary, until said
         repairs, alterations, replacements or improvements, shall have been
         completed.  Landlord shall have no responsibility or liability for
         failure to supply air conditioning during said period mentioned just
         above or when prevented from so doing by any cause beyond Landlord's
         reasonable control or by laws, orders or regulations of any Federal,
         State, County or Municipal authorities and Tenant shall be entitled to
         no diminution or abatement of Rent by reason of the stoppage of such
         air cooling or conditioning for any of the aforesaid reasons
         whatsoever nor shall the same in any way affect the obligation of
         Tenant to perform and fulfill its covenants under this Lease.
         Landlord agrees to make any repairs to the air conditioning system
         promptly and with due diligence.

                 Whenever heavy concentration of personnel, motors, machines or
         equipment, including telephone equipment, used in the Leased Premises
         adversely affect the temperature or humidity otherwise maintained by
         the air conditioning system, Landlord reserves the right to install
         supplementary air conditioning units in the Leased Premises and the
         cost thereof, including the cost of installation and the cost of
         operation and maintenance thereof, shall be paid by Tenant to Landlord
         upon demand by Landlord.

                 (c)      EXTRA HOURS.  Landlord may also furnish heat and air
         conditioning at such other times as are not provided for above on
         condition that Tenant gives Landlord not less than two (2) business
         days notice of Tenant's needs for such additional heating or air
         conditioning and provided Tenant pays to Landlord its regular charges
         for such additional heating or air conditioning at rates to be
         established from time to time.  Such charges will be prorated by
         Landlord between requesting user-tenants if more than one tenant in
         the Building requests such additional heating or air conditioning at
         overlapping times and the proration shall be based on the area of the
         Building leased to such tenants and their respective periods of use.

                 (d)      WATER.  Landlord shall furnish cold water from
         regular Building outlets for drinking, lavatory and toilet purposes
         drawn through fixtures installed by Landlord, and hot water for
         lavatory purposes from the regular supply of the Building.  Tenant
         shall pay Landlord at rates fixed by Landlord for water furnished for
         any other purpose as Additional Rent hereunder.  Tenant shall not
         waste or permit the waste of water.  Landlord shall furnish water as
         provided by the Village of Oak Brook without any additional treatment.

         janitorial and cleaning services as set forth in Appendix E - Cleaning
         Specifications, which specifications may be amended from time to time
         hereafter.  Tenant shall not provide janitor services without the
         prior written consent of Landlord and then only subject to the
         supervision of Landlord (but not as agent or servant of Landlord) and
         at Tenant's sole responsibility, cost and expense, by contractors or
         employees satisfactory to Landlord.

                 (f)      ELEVATOR SERVICE.  Landlord shall furnish
         operatorless passenger elevator service in common with Landlord and
         other tenants.  Freight elevator service shall be available in common
         with Landlord and other tenants and any use of the freight elevator
         service by Tenant and contractors or employees of Tenant shall be at
         Tenant's sole responsibility and expense and at times satisfactory to
         and subject to scheduling by Landlord.  Tenant shall abide by all
         rules and regulations established by Landlord from time to time with
         respect to the use of passenger elevator service and freight elevator
         service.

                 (g)      WINDOW COVERINGS.  Landlord shall determine treatment
         for exterior windows of standard type and color for the Building,
         which Tenant agrees not to remove or alter.

                 (h)      ELECTRICITY.  Landlord will furnish all electricity
         consumed in the Leased Premises.  Tenant shall pay for all electricity
         required during janitorial service and for alterations and repairs to
         the Leased Premises.  Tenant shall also pay for all electricity
         required for the operation of any special air conditioning,
         ventilating, office machinery, or equipment requiring extra
         electricity.

         Tenant covenants and agrees that Landlord shall in no event be liable
         or responsible to Tenant for any loss, damage or expense which Tenant
         may sustain or incur if either the quality or character of electrical
         service is changed or is no longer suitable for Tenant's requirements.
         Tenant covenants and agrees that at all times its use of electric
         current shall never exceed the capacity of existing feeders to the
         Building when reviewed in conjunction with electrical usage of other
         tenants in the Building or in the Leased Premises or wiring or
         installation; and also that it shall make no alterations or additions
         to the electric equipment and/or appliances without obtaining the
         prior written consent of Landlord in each instance.

                 (1)      Separately metered electricity.  In the event the
                 Leased Premises are separately metered, Tenant shall make
                 arrangements directly with the utility servicing the Building
                 and shall pay the entire cost of all electricity consumed
                 within the Leased Premises.

                 (2)      Not separately metered electricity.  In the event the
                 Leased Premises are not separately metered for electricity,
                 Tenant shall pay Landlord on a flat rate basis for the cost of
                 such electricity at the rate shown on the Schedule.  Payment
                 of such annual rate shall be made in 12 monthly installments
                 of one-twelfth (1/12) of such annual rate on the first day of
                 each calendar month during the Term and shall be deemed to be
                 additional Rent hereunder.  Landlord shall have the exclusive
                 right to adjust Tenant's annual rate for electricity at any
                 time to reflect any increase in the cost of electricity to
                 Landlord or any increase in use of electricity by Tenant.

                 At any time hereafter, and to the extent permitted or required
                 by law or regulation, Landlord shall have the option to
                 require Tenant to pay such electricity charges directly to the
                 utility supplying the electricity and to have Tenant reimburse
                 Landlord for the cost of separate





                                     - 8 -
<PAGE>   31
         meters serving the Leased Premises and for the cost of installation
         thereof and in that event the monthly charge referred to in Section
         5.00 (i)(2) above shall be discontinued.

                 (i)      INTERRUPTION OF SERVICE.  Landlord does not warrant
         that any service or any equipment used in connection with the services
         stated herein will be free from interruptions and Landlord reserves
         the right to temporarily discontinue such service as may be necessary
         by reason of repairs, renewals or improvements, by strike, lockout or
         other labor controversies, accidents, inability to obtain fuel, steam,
         water or supplies, governmental regulations, any accident or casualty
         whatsoever, the act or default of Tenant or other persons or other
         causes beyond the reasonable control of Landlord.  No such
         interruption of service shall be deemed an eviction or disturbance of
         Tenant's use and possession of the Leased Premises or any part
         thereof, or render Landlord liable to relieve Tenant from performance
         of Tenant's obligations under this Lease, nor shall Tenant be entitled
         to diminution or abatement of Rent by reason of the unavailability of
         said service. Tenant hereby waives and releases all claims against
         Landlord for damages for interruption or stoppage of service.  Should
         service to Tenant be interrupted due to Landlord's negligent or
         willful act or failure to act for five (5) consecutive business days
         or longer, Base Rent shall be abated on a per diem basis for the
         period and to the extent that Tenant is unable to utilize the Leased
         Premises due to the unavailability of air conditioning, water, heat or
         electricity.  Notwithstanding anything contained herein to the
         contrary, except when Landlord is prevented from so delivering said
         service by any cause beyond Landlord's reasonable control or by laws,
         orders or regulations of any federal, state, county or municipal
         authorities, should service to Tenant be interrupted for one hundred
         eighty (180) consecutive days, Tenant may, upon thirty (30) days'
         prior written notice to Landlord, terminate this Lease, provided that
         Rent shall be paid through the date such service was interrupted.
         Landlord shall not be obligated to provide any services other than
         those expressly set forth above.  The foregoing notwithstanding, if
         Landlord provides any additional work or services requested by Tenant
         or provides any unusual amount of the work or services provided
         (including service furnished outside any stipulated hours), Tenant
         shall pay Landlord, as Additional Rent hereunder, at rates as Landlord
         may from time to time establish.

         6.00    TENANT'S OBLIGATIONS.

         6.01    REPAIRS.  Except for ordinary wear and as otherwise provided
in this Lease, Tenant shall at all times during the Term hereof, at its sole
expense, keep the Leased Premises and every part thereof in good order, repair
and condition, and Tenant shall arrange with Landlord at Tenant's sole expense
for the prompt repair of all damages to the Leased Premises and the replacement
or repair of all damaged or broken glass (including signs thereon), fixtures
and appurtenances (including hardware and heating, cooling, ventilating,
electrical, plumbing and other mechanical facilities in the Leased Premises),
with materials equal in quality and class to the original materials damaged or
broken, all repairs and replacements to be made under the supervision and with
the prior written approval of Landlord, using contractors or persons designated
by Landlord.  If Tenant does not promptly make such arrangements, Landlord may,
but need not, make such repairs and replacements and the amount paid by
Landlord for such repairs and replacements shall be deemed Additional Rent
reserved under this Lease due and payable forthwith.  Landlord and its
designees may, but shall not be required to, enter the Leased Premises at all
reasonable times to make any repairs, alterations, improvements or additions,
including, but not limited to, ducts and all other facilities for heating and
air conditioning service, as Landlord shall desire or deem necessary for the
safety, preservation or improvement of the Property, or as Landlord may be
required to do by any governmental authority or court order or decree.  The
cost of all repairs to the Property made necessary as a result of misuse or
neglect by Tenant or Tenant's employees, invitees or agents including a
percentage





                                     - 9 -
<PAGE>   32
thereof sufficient to reimburse Landlord for overhead, general conditions, fees
and other costs arising from Landlord's involvement in said repairs, shall be
immediately paid as Additional Rent by Tenant to Landlord upon being billed for
same.

         6.02    DOORS TO BE LOCKED.  Before leaving the Leased Premises
unattended, Tenant shall close and securely lock all doors providing access to
the Leased Premises to the extent the controls for same are within the Leased
Premises, shut off all utilities in the Leased Premises.  Any damage resulting
from failure to do so shall be paid by Tenant.

         6.03    HOLDING OVER.  Tenant shall pay to Landlord the monthly Rent
computed on a per month basis for each month or part thereof (without reduction
for any such partial month) Tenant retains possession of the Leased Premises or
any part thereof after the expiration of the Term, by lapse of time or
otherwise, at double the amount of the Rent then required by the terms hereof
for the last monthly period prior to the date of such expiration and also pay
all damages, direct or indirect, sustained by Landlord by reason of such
retention beyond a period of thirty (30) days, or, if Landlord gives notice in
writing to Tenant (and not otherwise), such holding over shall constitute
renewal of this Lease at Landlord's election for either (i) two hundred percent
(200%) of the then current Rent (including Additional Rent); or (ii) that
amount set forth in a written notice from Landlord to Tenant prior to the
holding over, but acceptance by Landlord of Rent after such expiration shall
not constitute a renewal or extension nor waive Landlord's right of re-entry or
any other right of Landlord.

         6.04    LAWS, RULES AND REGULATIONS.  With respect to the Leased
Premises and the use and occupancy thereof, Tenant agrees that it and its
employees, agents, clients, customers, invitees, visitors and guests will
comply with all rules and regulations ("Rules and Regulations") Landlord may
adopt from time to time for the use, safety, cleanliness and care of the
Property and its tenants and occupants, and to comply with all laws,
ordinances, orders, Rules and Regulations, and all decrees of court and with
the directions of any governmental department or agency.  Present Rules and
Regulations of Landlord are contained in Appendix F.  The violation of the
Rules and Regulations governing Tenant's use of the Leased Premises shall be a
default under this Lease allowing Landlord all remedies for default provided
under this Lease and any remedies available at law or in equity, including the
right to enjoin any breach of such Rules and Regulations.  Landlord shall not
be responsible to Tenant for violation of Rules and Regulations or terms of
this Lease by another tenant nor shall failure to obey the same by others or
lack of enforcement relieve Tenant from its obligations to comply therewith.
Modifications or additions to the Rules and Regulations will be effective upon
notice to Tenant from Landlord and in the event of any conflict between the
provisions of this Lease and the Rules and Regulations, the provisions of this
Lease will govern.  Landlord shall use reasonable efforts to enforce the rules
and regulations of the Building in a uniform and non-discriminatory manner.

         6.05    UNLAWFUL USE.  Tenant shall not make or permit any use of the
Leased Premises which, directly or indirectly, is forbidden by law, ordinance,
governmental or municipal regulations or order, or which may be dangerous to
life, limb or property.

         6.06    HAZARDOUS MATERIALS.  Tenant shall not use or permit to be
brought into or kept in the Leased Premises or on the Property any inflammable
oils or fluids, or any explosive or other articles deemed hazardous to person
or property; or do or permit to be done any act or thing which will invalidate
or be in conflict with fire or other insurance policies covering the Property
or its operation, or the Leased Premises, or part of either, or do or permit to
be done anything in or upon the Leased Premises, which shall not comply with
all rules, orders, regulations or requirements of the Illinois Inspection and
Rating Bureau, the Fire Insurance Rating Organization, the Board of Fire
Underwriters, or any similar organization





                                     - 10 -
<PAGE>   33
(and Tenant shall at all times comply with all such rules, regulations or
requirements), or which shall increase the rate of insurance on the Property,
its appurtenances or contents.  If by reason of the failure of Tenant to comply
with the provisions of this paragraph, including, but not limited to, the use
to which Tenant shall put the Leased Premises, any insurance coverage is
jeopardized or insurance premiums are at any time increased above what they
otherwise would be, Landlord shall have the option, in addition to its other
rights and remedies, either to terminate this Lease or to require Tenant to
make immediate payment of the increased insurance premium as Additional Rent.

         6.07    VARIOUS PROHIBITED USES.  Tenant shall not install or operate
any refrigerating, heating or air conditioning apparatus or carry on any
mechanical business without the prior written consent of Landlord; use the
Leased Premises for housing, lodging or sleeping purposes or for any immoral or
illegal purposes; permit preparation or warming of food in the Leased Premises
(warming of coffee and individual meals of employees excepted); permit food to
be brought into the Leased Premises for sale or consumption therein except
coffee and individual meals of employees, without the prior written consent of
Landlord, or permit the manufacture, sale, purchase, use or gift of any
alcoholic liquors in the Leased Premises or on the Property.  Landlord may in
its sole discretion refuse permission or impose any conditions in granting it,
and revoke it at will.

         6.08    SOUND DEVICES.  Tenant shall not place any radio or television
antenna aerial wires or other equipment on the roof or on or in any part of the
inside or outside of the Building other than the inside of the Leased Premises;
operate or permit to be operated any musical or sound producing instrument or
device inside or outside the Leased Premises which may be heard outside the
Leased Premises; or operate any electrical device which may interfere with or
impair radio or television broadcasting or reception from or in the Property or
elsewhere.

         6.09    ADDITIONAL LOCKS.  Tenant shall not attach or permit to be
attached additional locks or similar devices to any door, transom or window;
change existing locks or the mechanism thereof; or make or permit to be made
any keys for any door other than those provided by Landlord.  (If more than two
(2) keys for one (1) lock are desired, Landlord will provide them upon payment
therefor by Tenant.)

         6.10    OVERLOAD ANY FLOOR.  Tenant shall not overload any floor.

         6.11    DEFACING LEASED PREMISES.  Except for Decoration (as
hereinafter defined), Tenant shall not do any painting or decorating in the
Leased Premises; or mark, paint, cut or drill into, drive nails or screws into,
or in any way deface any part of the Leased Premises or the Building, outside
or inside, without the prior written consent of Landlord.  (If Tenant desires
signal, communication, alarm or other utility security or alarm systems, or
service connections installed or changed, the same shall be made by and at the
expense of Tenant, with the written approval and under direction of Landlord.)
For purposes of this Section 6.11 and Section 6.12 of this Lease, "Decoration"
shall be deemed to mean any alteration, improvement, addition, installation or
construction (for example, painting the interior walls, installing carpeting or
picture hanging) in or to the Leased Premises or any Building systems serving
the Leased Premises by the Tenant which does not require a building permit and
which does not involve any of the structural elements of the Building, or any
of the Building's systems, including, without limitation, its electrical,
mechanical, plumbing and security and life/safety systems.  Subject to all
other requirements of this Section 6.11 and Section 6.12, Tenant may undertake
Decoration work without Landlord's prior written consent.

         6.12    ALTERATIONS.  Except for Decoration, Tenant shall not do any
painting or decorating, erect any partitions, make any installations,
alterations, improvements or additions in or to the





                                     - 11 -
<PAGE>   34
Leased Premises without submitting plans and specifications to Landlord and
securing the prior written consent of Landlord in each instance.  Landlord need
not give its consent, but if Landlord does, it may impose such conditions with
respect thereto as Landlord deems appropriate, including, without limitation,
requiring Tenant to furnish Landlord with security for the payment of all costs
to be incurred in connection with such work and insurance against liabilities
that may arise out of such work.  Such work shall be done at the sole cost and
expense of Tenant by employees of or contractors employed by Landlord, or with
Landlord's consent in writing given prior to letting of contract, by
contractors employed by Tenant, but in each case, only under written contract
previously approved in writing by Landlord.  All installations, alterations,
improvements and additions shall be constructed in a good and workmanlike
manner and only new and good grades of material shall be used, with quality at
least equal to that used in the Building and shall comply with all insurance
requirements, and with all applicable laws, ordinances, rules and regulations
of governmental departments or agencies.  Tenant shall promptly pay when due
the cost of all such work and of decoration required by reason thereof and
reimburse Landlord for its cost, including reasonable compensation for
Landlord's general conditions, fees and other costs and expenses arising from
the involvement of Landlord or Manager in such work.  Tenant shall permit
Landlord to supervise all construction operations within the Leased Premises.
If alterations are made by Tenant's contractors, Tenant shall furnish to
Landlord prior to commencement thereof building permits, bonds and certificates
of appropriate insurance, title insurance or bond for mechanics' liens, and
each shall name Landlord as an additional insured party, and upon completion of
any installation, alteration, improvement or addition, Contractor's Affidavits
and full and final Waivers of Lien covering all labor and material expended and
used.  Tenant shall hold Landlord harmless from all claims, costs, damages,
liens and expenses which may arise out of or be connected in any way with said
installations, alterations, improvements or additions.  All alterations,
additions, fixtures and improvements, whether temporary or permanent in
character, made in or upon the Leased Premises either by Tenant or Landlord
will immediately become Landlord's property and at the end of the Term remain
in the Leased Premises without compensation to Tenant unless Landlord notifies
Tenant at the time such alterations, additions, fixtures or improvements are
approved that such alterations, additions, fixtures or improvements must be
removed by Tenant on or before the end of the Term in compliance with the
requirements of this Section 6.12.

         Any work permitted to be undertaken by Tenant shall be performed in
such a fashion and by such means as necessary to maintain peace and harmony
among the other contractors including, but not limited to, collective
bargaining agreements and organizations serving the Property and the other
tenants and so as not to cause interference with the continuance of work to be
performed or services to be rendered to the Property or the other tenants.

         Tenant agrees to protect, defend and indemnify Landlord, its officers,
agents and employees, the Leased Premises and the Property from and against any
and all liabilities of every kind and description which may arise out of or be
connected in any way with said alterations, improvements or repairs or the like
whether performed by or under the direction of Landlord and at the cost of
Tenant or performed by Tenant.  Any mechanics' lien filed against the Leased
Premises or the Property or any notice which is received by either Landlord or
Tenant for work or materials furnished or claimed to be furnished to Tenant or
the Leased Premises shall be released and discharged by Tenant; and, if such
lien or notice is filed, it shall be released and discharged of record by
Tenant, in either case, within ten (10) days after such filing or receipt,
whichever is applicable, at Tenant's expense.  If Tenant chooses to contest
such claim, notice or lien, Tenant may do so in place of causing the release
and discharge thereof provided Tenant, within said ten (10) day period,
delivers to Landlord security reasonably required by Landlord to guarantee over
such claim or lien.  Upon completion of any of the above-mentioned work in this
Section 6.00 and its subdivisions, Tenant shall furnish Landlord with
contractors' affidavits and full and final waivers of lien, each conforming to
the applicable Illinois statutory requirements, and receipted bills covering
all labor and materials expended and used.  Insofar as applicable to the work
or material for which payment is requested or notice or lien claim





                                     - 12 -
<PAGE>   35
is made, Landlord in its sole discretion shall make available for partial or
final payment or release thereof such funds as may have been deposited with it
by Tenant for the estimated cost of such work.  Landlord may require that
Tenant remove any or all alterations, additions, fixtures and improvements
which were made in or upon the Leased Premises after the initial improvements
to the Leased Premises, provided Landlord notifies Tenant at the time Landlord
is aware of and is asked to consent to such alteration, additions, fixtures and
improvement that Tenant will be required to remove same at the end of the Term.
In that event, Tenant shall remove such alterations, additions, fixtures and
improvements at Tenant's sole cost and will restore the Leased Premises to the
condition in which they were before such alterations, additions, fixtures,
improvements and additions were made, reasonable wear and tear excepted.

         Tenant will have the right to install or relocate free standing work
station partitions either as part of the initial improvement of the Leased
Premises, or, after such initial improvement, without Landlord's prior written
consent, so long as no building or other governmental permit is required for
their installation or relocation; however, if a permit is required, Landlord
will not unreasonably withhold its consent to such relocation or installation.
Tenant acknowledges that any installation or relocation of such partition may
affect the heating, cooling, power and lighting required by the Leased Premises
and any increased costs attributable to such changes will be payable by Tenant
to Landlord as Additional Rent.  The free standing work station partitions for
which Tenant pays will be part of Tenant's trade fixtures for all purposes
under this Lease.  All other partitions which are installed in the Leased
Premises are and will be Landlord's property for all purposes under this Lease.

         7.00    RIGHTS RESERVED TO LANDLORD.  Landlord shall have the
following rights exercisable without notice and without liability to Tenant for
damage or injury to property, person or business (all claims against Landlord
for damage being hereby released), and the exercise thereof shall not be deemed
to effect an eviction or disturbance of Tenant's use or possession or give rise
to any claim for setoff, or abatement of Rent or any other claim or affect any
of Tenant's obligations hereunder:

         7.01    CHANGE NAME OR ADDRESS.  To change the name or street address
of the Building or Property;

         7.02    SIGNS.  To install and maintain signs on the exterior and

otherwise prepare the Leased Premises for reoccupancy any time after Tenant
vacates or abandons the Leased Premises.  Such acts of Landlord shall not
relieve Tenant of its obligation to pay Rent to the Termination Date;

         7.06    INSPECT AND EXHIBIT.  To enter the Leased Premises at
reasonable hours to make inspections, or to exhibit the Leased Premises to
prospective tenants, lenders, purchasers or others, or for other reasonable

the rules of the United States Post Office;

reasonably determine to identify themselves to a watchman by registration or
otherwise and to establish their right to leave or enter, and to exclude or
expel any peddler, solicitor or beggar at any time from the Leased Premises or
the Property; and to require Tenant, its employees, agents, and visitors to
enter and exit the Property at locations and in such fashion as Landlord may
designate from time to time, and in all other respects to control the entrance
and access to the Property;

         7.09    LOCATION APPROVAL.  To approve the weight, size and location
of safes, filing cabinets or systems, computers, all other heavy articles in
and about the Leased Premises and the Building and to require all such items
and other office furniture and equipment to be moved in and out of the Property
and Leased Premises only at such time and in such manner as Landlord shall
direct and in all events at Tenant's sole risk and responsibility;

         7.10    REPAIRS.  At any time or times, to decorate and to make
repairs, alterations, additions and improvements, structural or otherwise, in
or to the Leased Premises, the Property or part thereof, to erect, use and
maintain pipes, ducts, wiring and conduits in and through the Leased Premises,
and to perform any acts related to the safety, protection or preservation
thereof, and during such operations to take into and through the Leased
Premises or any part of the Property all material and equipment required, to
close or temporarily suspend operation of entrances, doors, corridors,
elevators or other facilities, to change the arrangements and/or location of
entrances or passageways, doors, and doorways and corridors, stairs, elevators,
toilets or other public parts of the Building or Property and to close
entrances, doors, corridors or other facilities.  The exercise of the foregoing
rights shall not diminish any of Tenant's obligations hereunder as long as the
Leased Premises are reasonably accessible.  If any such action permanently
reduces the size of the Leased Premises, Rent shall be proportionately reduced.
Landlord may do such work during ordinary business hours and Tenant shall pay
Landlord for overtime and for any other expenses incurred if such work is done
during other hours at Tenant's request.  Landlord shall not be liable to Tenant
for any expense, injury, loss or damage resulting from work done in or upon or
the use of any adjacent or nearby building, land, street or alley;

         7.11    ADJACENT WORK.  To do or permit to be done any work in or
about the Leased Premises or the Property or any adjacent or nearby building,
parking garage, parking deck, parking lot, land, street or alley;

         7.12    EXCLUSIVE RIGHTS.  To grant to anyone the exclusive right to
conduct any business or render any service on the Property, provided such
exclusive right shall not operate to exclude Tenant from the use expressly
permitted to Tenant pursuant to this Lease;

         7.13    VENDING MACHINES.  To prohibit the placing of vending or
dispensing machines of any kind in or about the Leased Premises;

         7.14    RELOCATE TENANT.  To require Tenant to move to "equivalent
space" on any floor (other than the first four floors) or Building in the
Property upon receipt of thirty (30) days' written notice from Landlord, in
which event Landlord shall pay all reasonable moving costs, and the Rent
provided for herein shall remain the same.  For purposes of this Section 7.14,
"equivalent space" shall be deemed to mean a space on the fifth, sixth or
seventh floor of any Building in the Property which has approximately





                                     - 14 -
<PAGE>   37
the same rentable square feet, approximately the same amount of window line as
in the original Leased Premises with similar views to the West of the Leased
Premises, and similar identification and visibility from the elevator lobby.
Upon the effective date of such relocation this Lease will be amended by
deleting the description of the original Leased Premises and substituting for
it a description of such comparable space;

         7.15    WINDOW TREATMENTS.  To designate and approve, prior to
installation, all types of window shades, blinds, drapes, awnings, window
ventilators and other similar equipment and to control all the internal

lock box collection agent to act as Landlord's agent for the collection of
amounts due Landlord.  In such event the date of payment of Rent or other sums
paid Landlord through such agent shall be the date of agent's receipt of such
payment (or the date of collection of any such sum if payment is made in the
form of a negotiable instrument thereafter dishonored upon presentment);

         7.17    EMERGENCY ACCESS.  To enter the Leased Premise in the event of
an emergency and undertake repairs and/or take such other actions as
appropriate under the circumstances;

         7.18    EXERCISE ALL OTHER RIGHTS.  To take any and all measures,
including inspections, repairs, remodeling, alterations, additions and
improvements to the Leased Premises or to the Property, as may be necessary or
desirable for the safety, protection or preservation of the Leased Premises or
the Property for the Landlord's interests, or as may be necessary or desirable
in the operation of the Property, and to take any acts related thereto, and
such acts and reasonable disruptions related thereto shall not be considered a
disturbance or a constructive eviction of Tenant.

         8.00    LANDLORD'S TITLE.  Landlord's title is and always shall be
paramount to the title of Tenant hereunder.  Nothing herein contained shall
empower Tenant to do any act which can, shall or may encumber the title of
Landlord.

         9.00    QUIET ENJOYMENT.  Landlord covenants that Tenant, on paying
the Rent and other payments provided herein, all of which obligations of Tenant
are independent of Landlord's obligations under this Lease, and keeping,
observing and performing the covenants, conditions, provisions and agreements
of this Lease on its part to be kept, observed and performed, shall and may
peaceably and quietly have, hold and enjoy the Leased Premises for the Term of
this Lease, subject to the provisions of this Lease.

         10.00   WAIVER OF CERTAIN CLAIMS.  To the fullest extent now or
hereafter permitted by law, Tenant waives and releases all claims against
Landlord, and its respective officers, directors, agents, employees and
servants, in respect of, and they shall not be liable for, injury to person or
damage to property sustained by Tenant or by any occupant of the Leased
Premises or the Property or any other person occurring in or about the Property
resulting directly or indirectly from any existing or future condition, defect,
matter or thing in the Leased Premises, the Property or any part of it, or from
equipment or appurtenance therein, or from accident, or from any occurrence,
act, negligence or omission of any tenant or occupant of the Property, or of
any other person, including, without limitation, Landlord, its officers,
directors, agents, employees and servants.  This Section shall apply
especially, but not exclusively, to damage caused by leaking roofs, flooding of
basements or other sub-surface areas or by refrigerators, sprinkling devices,
air conditioning or heating apparatus, water, snow, frost, steam, excessive
heat or cold, falling plaster, broken glass, sewage, sewer gas or odors, noise,
fire, water or the bursting or leaking of pipes or plumbing fixtures, and shall
apply equally whether any such damage results from the act or





                                     - 15 -
<PAGE>   38
omission of other tenants, occupants or servants of the Property or of any other
persons, including Landlord, or any of its respective officers, directors,
agents, employees and servants, and whether such damage be caused or result from
any thing or circumstance above mentioned, or any other thing or circumstance
whether alike or wholly different in nature.  If any such damage to the Leased
Premises or the Property or any equipment or appurtenance therein, or to tenants
thereof, results from any act or omission or negligence of Tenant, its agents,
employees or invitees, Landlord may, at Landlord's option, repair such damage
and Tenant shall, upon demand by Landlord, reimburse Landlord forthwith for all
costs of such repairs and damages both to the Property and to the tenants
thereof.  All property on the Property, in the Leased Premises, or elsewhere
belonging to Tenant, its agents, employees, or invitees, or to any occupant of
the Leased Premises shall be there at the risk of Tenant or other person only,
and Landlord shall not be liable for damage thereto or theft, misappropriation
or loss thereof.  Without limitation on any other provisions hereof, Tenant
agrees to protect, indemnify, defend, and hold Landlord harmless against
liability to Tenant, its employees and to third parties against claims,
liabilities and costs including, but not limited to, attorneys' fees and costs,
for injuries to all persons and for damage to, or the theft, misappropriation or
loss of any property occurring in or about the Leased Premises, or due to any
act or omission of Tenant, its agents or employees or invitees.

         11.00   PREPARATION AND CONDITION OF LEASED PREMISES.  Tenant
acknowledges that except to the extent indicated in the Tenant Improvement Work
Agreement and Building Standard Work set forth therein, Landlord is leasing the
Leased Premises "as is" without any representations or warranties.  If so
indicated on the Schedule, Landlord shall cause the Leased Premises to be
completed in accordance with the plans, specifications, and agreements and on
the terms, conditions and provisions as provided in the Tenant Improvement Work
Agreement.  Miscellaneous minor finishing items and adjustments ("Punch List
Items") shall be detailed on a list of such items developed during an inspection
of the Leased Premises by representatives of Tenant and Landlord and which items
shall be remedied within a reasonable time after Possession Date, subject to
availability of materials and labor.  In no event shall Tenant be entitled to
any credit against, or abatement of, Rent due to the existence of any Punch List
Items.

         12.00   LEASE TERMINATION.  At the termination of this Lease or
Tenant's right to possession by lapse of time or otherwise:

         12.01   SURRENDER OF KEYS.  Tenant shall surrender to Landlord all
keys and passes for offices, rooms, storage areas, parking lot and toilet rooms
which shall have been furnished Tenant and make known to Landlord the
explanation of all combination locks remaining on the Leased Premises.

         12.02   RETURN OF LEASED PREMISES.  Tenant shall return to Landlord
the Leased Premises and all equipment and fixtures of Landlord and flooring,
attached carpeting and other floor covering in the Leased Premises in good
condition and state of repair, subject, however, to (a) the provisions of
Sections 12.03 and 12.04 (b) ordinary wear, and (c) loss or damage by fire or
other casualty covered in Section 14.00 hereof, failing which Landlord may
re-enter the Leased Premises and restore the Leased Premises, equipment and
fixtures to such condition and state of repair and Tenant shall, upon demand,
pay to Landlord the cost thereof.

         12.03   REMOVAL OF ADDITIONS.  All installations, alterations,
additions, hardware, non-trade fixtures and improvements, temporary or
permanent, except movable furniture and equipment belonging to Tenant, in or
upon the Leased Premises, whether placed there by Tenant or Landlord, shall be
Landlord's property and shall be relinquished to Landlord in good condition,
ordinary wear and tear excepted, at the termination of this Lease or Tenant's
right to possession by lapse of time or otherwise, all without compensation,
allowance or credit to Tenant; provided, however, that if prior to such
termination





                                     - 16 -
<PAGE>   39
or within ten (10) days thereafter Landlord so directs by notice, Tenant shall
promptly remove the installations, alterations, additions, hardware, non-trade
fixtures and improvements placed in or upon the Leased Premises by Tenant and
designated in the notice, failing which Landlord may remove the same and Tenant
shall, upon demand, pay to Landlord the cost of such removal and of any
necessary restoration of the Leased Premises.  Notwithstanding anything herein
to the contrary, Tenant shall not be required to remove at the termination or
expiration of this Lease or Tenant's right to possession hereunder, any
permanent partitions or other permanent installations in place as of the
Commencement Date, except for the pneumatic tube running through the ceiling of
the lower level of the Building.  During the Term, Landlord shall upon request
of Tenant, provide Tenant in advance a determination regarding Tenant's
obligation to remove any proposed installations, additions, fixtures or
improvements which determination shall be binding on all parties.  The
provisions of this Section shall survive the termination of this Lease.

         12.04   ABANDONMENT AND REMOVAL OF PROPERTY.  All fixtures,
installations, and personal property belonging to Tenant not removed from the
Leased Premises upon termination of this Lease or Tenant's right to possession
and not required by Landlord to have been removed as provided herein shall be
conclusively presumed to have been abandoned by Tenant and title thereto shall
pass to Landlord under this Lease as by a bill of sale without any cost,
whether by set-off, credit, allowance or otherwise, and Landlord may, at its
option, accept the title to such property or, at Tenant's expense, may (i)
remove the same or any part in any manner that Landlord shall choose and (ii)
store, destroy or otherwise dispose of the same without incurring liability to
Tenant or any other person.  Any such property of Tenant not removed from the
Leased Premises or retaken from storage by Tenant within thirty (30) days after
the end of the Term, however, terminated or any extension thereof, at
Landlord's sole option, shall be conclusively deemed to have been forever
abandoned by Tenant.  All property which may be removed from the Leased
Premises by Landlord, may be handled, removed or stored in a commercial
warehouse or otherwise by Landlord at the risk, cost and expense of Tenant, and
Landlord shall in no event be responsible for the value, preservation and
safekeeping thereof.  Tenant shall pay to Landlord, upon demand, any and all
expenses incurred in such removal and all storage charges against such property
so long as the same shall be in Landlord's possession or under Landlord's
control.

         13.00   ASSIGNMENT AND SUBLETTING.  Tenant shall not, without the
prior written consent of the Landlord in each instance; (1) 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; (ii) allow to exist or occur any transfer of or lien upon this Lease or the
Tenant's interest herein by operation of law; (iii) sublet the Leased Premises
or any part thereof; or (iv) permit the use or occupancy of the Leased Premises
or any part thereof for any purpose not provided for under Section 4.00 of this
Lease or by anyone other than Tenant and Tenant's employees.  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.  Notwithstanding anything to the contrary contained
in this Section 13.00, Tenant shall have the right, without the prior written
consent of Landlord, to sublease the Leased Premises, or to assign this Lease
to an Affiliate (as hereinafter defined) provided said assignment or sublease
shall not release or discharge tenant of or from any liability, whether past,
present or future, under this Lease, and Tenant shall continue fully liable
hereunder.  For purposes of this Section 13.00, "Affiliate" shall be deemed to
mean any corporation or other business entity which is currently owned or
controlled by, owns or controls, or is under common ownership or control with
Tenant or purchases 100% of Tenant's assets.

                 If Tenant shall, by notice in writing, advise Landlord that it
intends, on a stated date (which shall not be less than sixty (60) days after
the date Landlord receives Tenant's notice), to assign or transfer its interest
as Tenant under this Lease, or to sublet any part or all of the Leased Premises
for the balance





                                     - 17 -
<PAGE>   40
or any part of the Term, Landlord shall have the right, but not the obligation,
to be exercised by giving written notice to Tenant within thirty (30) days
after Landlord's receipt of Tenant's notice, to terminate this Lease with
respect to the space therein described as of the date stated in Tenant's
notice.  Tenant's said notice shall state the name and address of the proposed
assignee or subtenant and a true and complete copy of the proposed sublease or
assignment and of all related documents shall be delivered to Landlord with
said notice.  If Tenant's notice shall cover all of the Leased Premises, and
Landlord shall give the aforesaid termination notice, the Term of this Lease
shall expire and end on the date stated in Tenant's notice as fully and
completely as if that date had been herein definitely fixed for the expiration
of the Term.  If, however, this Lease be cancelled pursuant to the foregoing
with respect to less than the entire Leased Premises, the Rent herein reserved
shall be adjusted on the basis of the number of Rentable Square Feet retained
by Tenant in proportion to the number of Rentable Square Feet in the entire
Leased Premises, and this Lease, as so amended, shall continue thereafter in
full force and effect.  If Landlord, upon receiving Tenant's said notice with
respect to any such space, shall not exercise its right to cancel as aforesaid,
Landlord will not unreasonably withhold its consent to Tenant's assignment as
aforesaid or subletting the space covered by its notice.  If this Lease is
terminated in whole or in part as aforesaid, Landlord shall be free to deal
directly with any such proposed assignee or sublessee without any
responsibility or liability to Tenant on account thereof.

                 Any subletting or assignment and collection of Rent from said
subtenant or assignee hereunder shall not release or discharge Tenant of or
from any liability, whether past, present or future, under this Lease, and
Tenant shall continue fully liable hereunder.  The subtenant or subtenants or
assignee shall agree to comply with and be bound by all of the terms,
covenants, conditions, provisions and agreements of this Lease to the extent of
the space sublet or assigned, and Tenant shall deliver to Landlord promptly
after execution an executed copy of each such sublease or assignment and an
agreement of compliance by each such subtenant or assignee.

                 Notwithstanding anything to the contrary in this Section
13.00, if Tenant is a corporation whose shares of stock are not publicly traded
or a partnership and if during the Term of this Lease the ownership of the
shares of stock which constitutes control of Tenant or more than fifty percent
(50%) of all general partnership interests changes by reason of sale, transfer
by operation of law or otherwise, gift or death, whether in a single
transaction or in a series of related or unrelated transactions, Tenant shall
notify Landlord of such change within five (5) days thereof, and Landlord, at
its option, may at any time thereafter terminate this Lease by giving Tenant
written notice of said termination at least sixty (60) days prior to the date
of termination stated in the notice.  The term "control" as used herein means
the power to directly or indirectly direct or cause the direction of the
management or policies of Tenant.

                 If Tenant shall assign or transfer its interest in this Lease
or sublet the Leased Premises having first obtained Landlord's consent at a
rental in excess of the Rent due and payable by Tenant under the provisions of
Section 2.00 and of this Lease, fifty percent (50%) of said Excess Rent shall
be paid to the Landlord.  Tenant agrees that Landlord's failure to consent
shall be deemed reasonable if, (i) in Landlord's opinion, the nature of the
business of an assignee, sublessee or transferee (a) is inconsistent with any
other tenant leases containing provisions against Landlord's leasing space in
the Property for certain uses, or (b) may have an adverse impact upon the
first-class, high-grade manner, in which the Property is operated or with the
high reputation of the Property, or (ii) the assignee, sublessee or transferee
is a tenant in the Property, a governmental entity, or is a high traffic
tenant, or has an unusually high parking requirement, even though in any of the
foregoing circumstances the potential assignee, sublessee or transferee may
have a good credit rating.

                 Any sale, assignment, mortgage, transfer or subletting of this
Lease which is not in compliance with the provisions of this Section shall be
of no effect and void.

         14.00   CASUALTY.  In the event (a) all or any portion of the Leased
Premises are made untenantable by fire or other casualty and Landlord shall
decide not to restore or repair same, or (b) the Property is so damaged by fire
or other casualty that Landlord shall decide to demolish or not rebuild the
same, then, in any of such events, Landlord shall have the right to terminate
this Lease by notice to Tenant within ninety (90) days after the date of such
fire or other casualty and the Rent shall be apportioned on a per diem basis
and paid to the date of such fire or other casualty and this Lease shall
terminate on the Notice Date (as hereinafter defined in Section 19.00).  In the
event all or any portion of the Leased Premises are made untenantable by fire
or other casualty and Landlord shall decide to rebuild and restore the same,
this Lease shall not terminate and Landlord shall repair and restore the Leased
Premises at Landlord's expense and with due diligence, subject, however, to (i)
reasonable delays for insurance adjustments and (ii) delays caused by forces
beyond Landlord's control.  Unless such damage is due to the fault or neglect
of Tenant, Base Rent shall abate on a per diem basis during the period of
reconstruction and repair, provided that in the event the Leased Premises are
partially damaged by fire or other casualty but are not made wholly
untenantable, Base Rent shall abate based on the proportion of the Leased
Premises that is untenantable.  If the damage is the result of the fault or
neglect or omission of Tenant, Base Rent shall not abate during said period.

                 Notwithstanding anything to the contrary herein set forth,
Landlord shall have no duty pursuant to this Section 14.00 to repair or restore
any portion of the alterations, additions or improvements in the Leased
Premises or the decoration thereto except to the extent that such alterations,
additions, improvements and decoration are included within the definition of
"Building Standard Work" (but not "Additional Work") in Appendix D attached
hereto.  If Tenant wants any other or additional repairs or restoration and if
Landlord consents thereto, the same shall be done at Tenant's expense subject
to all of the provisions of this Lease.

         15.00   RIGHTS AND REMEDIES OF LANDLORD.  All rights and remedies of
Landlord provided for in this Lease shall be cumulative and none shall exclude
any other right or remedy allowed by law or equity.

         15.01   PETITION IN BANKRUPTCY.  If any voluntary or involuntary
petition or similar pleading under any section or sections of any bankruptcy
act shall be filed by or against Tenant, or any voluntary or involuntary
proceeding in any court or tribunal shall be instituted to declare Tenant
insolvent or unable to pay Tenant's debts, or Tenant makes an assignment for
the benefit of its creditors, or a trustee or receiver is appointed for Tenant
or for any of Tenant's property, then and in any such event Landlord may, if
Landlord so elects but not otherwise, and with or without notice of such
election, and with or without entry or other action by Landlord, forthwith
terminate this Lease, and, notwithstanding any other provisions of this Lease,
Landlord shall forthwith upon such termination be entitled to recover damages
in an amount equal to the then present value of the Rent specified in Section
2.00 of this Lease for the residue of the Term hereof, less the fair rental
value of the Leased Premises for the residue of the Term.

         15.02   DEFAULT.  If Tenant defaults in the prompt payment of any Rent
and such default shall continue for five (5) or more days after the same
becomes due or in the performance or observance of any other provision of this
Lease and such other default shall continue for thirty (30) or more days after
notice thereof shall have been given to Tenant, or if a default involves a
hazardous condition and is not cured by Tenant immediately upon notice to
Tenant or if the leasehold interest of Tenant is levied upon under execution or
attached by process of law, or if Tenant vacates or abandons the Leased
Premises, then and in any such event Landlord, if it so elects, with or without
notice or demand, forthwith, or at any time thereafter while such default
continues, either may terminate Tenant's right to possession without
terminating this Lease, or may terminate this Lease.  However, Tenant will not
be entitled to more than one (1) notice





                                     - 19 -
<PAGE>   42
for monetary defaults during any twelve (12) month period, and if after such
notice any Rent is not paid when due, an event of default will be considered to
have occurred without further notice. If the term of any lease, other than this
Lease made by Tenant for any premises in the Property shall be terminated or if
Tenant`s right to possession thereunder is terminated, in either case because
of any default by Tenant under such other lease, Landlord may, at Landlord's
sole option, terminate Tenant's right to possession of the Leased Premises
without terminating this Lease, or terminate this Lease, by giving a notice to
such effect to Tenant.

         15.03   TERMINATION OF LEASE.  Upon termination of this Lease, whether
by lapse of time or otherwise, or upon any termination of Tenant's right to
possession without termination of this Lease, Tenant shall surrender possession
and vacate the Leased Premises immediately, and deliver possession thereof to
Landlord, and Tenant hereby grants to Landlord full and free license to enter
into and upon the Leased Premises in such event with or without process of law
and to repossess Landlord of the Leased Premises as of Landlord's former estate
and to expel or remove Tenant and any others who may be occupying or within the
Leased Premises and to remove any and all property therefrom, using such force
as may be necessary, without being deemed in any manner guilty of trespass,
eviction, forcible entry or detainer, or conversion of property, and without
relinquishing Landlord's right to Rent or any other right given to Landlord
hereunder or by operation of law.  Tenant expressly waives the service of any
demand for payment of Rent or for possession and the service of any notice of
Landlord's election to terminate this Lease or to re-enter the Leased Premises,
including any and every form of demand and notice prescribed by any statute or
other law, and agrees that the breach of any covenant or provision of this
Lease by Tenant, which breach shall continue beyond the period, if any,
provided herein for the curing thereof, shall, of itself, without the service
of any further notice or demand whatsoever, constitute a forcible detainer by
Tenant of the Leased Premises within the meaning of the statutes of the State
of Illinois.

         15.04   COLLECTION OF RENT UPON TERMINATION.  If Landlord is entitled,
and so elects, to terminate this Lease and the Term created hereby, Landlord
shall be entitled to recover forthwith as damages a sum of money equal to the
then present value of the Rent specified in Section 2.00 of this Lease for the
residue of the Term hereof, less the fair market value of the Rent for the
Leased Premises for the residue of the Term both discounted at the lesser of
eight percent (8%) or the discount rate at the New York Federal Reserve Bank on
the date of default.  Should the fair market value exceed the present value of
the Rent provided to be paid by Tenant for the balance of the Term hereof,
Landlord shall have no obligation to pay to Tenant the excess or any part
thereof.  In addition, Landlord may recover the unamortized cost of the Tenant
Improvement Work performed.

         15.05   TENANT ABANDONMENT.  If Tenant:

                 (i)(a)   vacates or abandons the Leased Premises; and

                 (i)(b)   fails to pay Rent and fails to perform all of
                          Tenant's obligations set forth herein; or

                 (ii)     otherwise entitles Landlord to elect, and if Landlord
                          so elects to terminate Tenant's right to possession
                          only, without terminating this Lease;

then Landlord may, at Landlord's option, enter upon the Leased Premises, remove
Tenant's signs and other evidences of tenancy, and take and hold possession
thereof as provided herein without such entry and possession terminating this
Lease, or releasing Tenant, in whole or in part, from Tenant's obligation to
pay the Rent hereunder for the Term, and in any such case Tenant shall pay
forthwith to Landlord a sum equal to the entire amount of the Rent specified in
Section 2.00 of this Lease for the residue of the Term plus any





                                     - 20 -
<PAGE>   43
other sums then due hereunder.  Upon and after entry into possession without
termination of this Lease, Landlord may, but need not, relet the Leased
Premises or any part thereof for the account of Tenant to any person, firm or
corporation other than Tenant for such Rent, for such time and upon such terms
as Landlord, in Landlord's sole discretion shall determine, and Landlord shall
not be required to accept any tenant offered by Tenant or to observe any
instructions given by Tenant about such reletting.  In any such case, Landlord
may make repairs, alterations and additions in or to the Leased Premises and
redecorate the same to the extent deemed by Landlord necessary or desirable,
and Tenant shall, upon demand, pay the cost thereof together with Landlord's
expenses of the reletting.  If the consideration collected by Landlord upon any
such reletting for Tenant's account is not sufficient to pay the full amount of
unpaid Rent reserved in this Lease, together with the cost of repairs,
alterations, redecorating and Landlord's expenses, Tenant shall pay to Landlord
the amount of any deficiency, upon demand.  If, in connection with reletting,
the new lease term extended beyond the existing Term, or the premises covered
by such new lease include other premises not part of the Leased Premises,
Landlord may allocate a fair portion of the Rent received from such reletting
and the expenses incurred in connection with such reletting as provided in this
Section in determining the net proceeds from such reletting, and any Rent
concessions will be equally apportioned over the term of the new lease.  With
respect to the provisions of the law of the State of Illinois, if any, which
requires that a Landlord mitigate the damages recoverable against a defaulting
lessee, Tenant agrees that Landlord shall have no obligation to relet the
Leased Premises to a potential substitute tenant (i) before Landlord rents
other vacant space in the Property; (ii) if the nature of the substitute
tenant's business is not consistent with any other tenant leases containing
provisions against Landlord leasing space in the Property for certain uses; or
(iii) if the nature of the substitute tenant's business may have an adverse
impact on the first-class high-grade manner in which the Property is operated
or with the high reputation of the Property, even though in each of the
aforesaid circumstances the potential substitute tenant may have a good credit
rating.

         15.06   INTEREST.  Any Rent or other sum due from Tenant to Landlord
not paid when due shall bear interest from the date due until the date paid at
a rate equal to three percent (3%) above the "Corporate Base Rate" as of the
first day of each applicable calendar month.  The term "Corporate Base Rate"
means that rate of interest announced by The First National Bank of Chicago
("First") from time to time as its "Corporate Base Rate" or successor
comparable rate of interest, changing automatically and simultaneously with
each change in the Corporate Base Rate made by First from time to time.  The
payment of such interest shall not excuse or cure any default of Tenant under
this Lease.

         15.07   LANDLORD'S COSTS.  Tenant shall pay on demand all Landlord's
reasonable costs, charges and expenses, including the fees of counsel, agents
and others retained by Landlord, incurred in enforcing Tenant's obligations
hereunder or incurred by Landlord in any litigation, negotiation or transaction
in which Tenant causes Landlord, without Landlord's fault, to become involved
or concerned.

         15.08   RESTRAINT OF VIOLATIONS.  If Tenant violates any of the terms
and provisions of this Lease, or defaults in any of its obligations hereunder,
other than the payment of Rent or other sums payable hereunder, such violations
may be restrained or such obligation enforced by injunction.

         15.09   LIEN ON TENANT'S PERSONAL PROPERTY.  Tenant hereby grants to
Landlord a first lien and security interest upon the interest of Tenant under
this Lease and a lien on the personal property of Tenant located in the Leased
Premises to secure the payment of Rent and other monies due under this Lease,
and Landlord shall have all rights of a secured party pursuant to the Uniform
Commercial Code of the State of Illinois or otherwise provided by law or
equity. Landlord's lien on the personal property of Tenant located in the
Leased Premises shall be secondary only to that of Tenant's secured creditor or
creditors who have a security interest and have provided financing with respect
to such personal property.





                                     - 21 -
<PAGE>   44
         16.00   EMINENT DOMAIN.  If any part of the Property (other than minor
takings for streets) shall be taken or condemned by any competent authority for
any public use or purpose, the Term of this Lease, at the option of Landlord,
shall end upon, and not before, the date when the possession of the part so
taken shall be required for such use or purpose, and without apportionment of
the award.  Rent shall be apportioned as of the date of such termination.
Tenant hereby expressly waives, releases and assigns to Landlord any right or
claim to any part of any award.  No money or other consideration shall be
payable by Landlord to Tenant for the right of cancellation.

         17.00   SUBORDINATION OR SUPERIORITY OF THIS LEASE.  The rights and
interest of Tenant under this Lease shall be subject and subordinate to any
first mortgage or first trust deed that exists now or may hereafter be placed
upon the Property and Building and to any and all advances to be made
thereunder, and to the interest thereon, and all renewals, replacements and
extensions thereof, if the mortgagee or trustee named in said mortgage or trust
deeds shall elect to subject and subordinate the rights and interest of Tenant
under this Lease to the lien of its mortgage or deed of trust.  Landlord will
use its reasonable efforts to procure a non-disturbance agreement on any future
mortgagee or trustee's standard form reasonably acceptable to Tenant".  Any
first mortgagee or first trustee may elect to give the rights and interest of
Tenant under this Lease priority over the lien of its mortgage or deed of
trust.  In the event of either such election, and upon notification by such
mortgagee or trustee or Landlord to Tenant to that effect, the right and
interest of Tenant under this Lease shall be deemed to be subordinate to or to
have priority over, as the case may be, the lien of said mortgage or trust
deed, whether this Lease is dated prior to or subsequent to the date of said
mortgage or trust deed.  Tenant shall promptly execute and promptly deliver
whatever instruments may be required for such purposes, and in the event Tenant
fails so to do within (10) days after demand in writing, and without limitation
of Tenant's liability for failing so to do, Tenant does hereby irrevocably
make, constitute and appoint Landlord, beneficiary of Landlord or the agent of
either, as its attorney in fact and in its name, place and stead so to do.

         18.00   SPRINKLERS.  If the sprinkler system installed on the Property
or any of its appliances shall be damaged or injured or not in proper working
order by reason of any act or omission or negligence of Tenant, Tenant's
agents, servants, employees, licensees or visitors, Tenant shall forthwith
restore the same to good working condition at its own expense; and if the Board
of Fire Underwriters or Fire Insurance Exchange or any bureau department or
official of the state or local government requires or recommends that any
changes, modifications, alterations or additional sprinkler heads or other
equipment be made or supplied by reason of Tenant's business or the location of
partitions, trade fixtures, or other contents of the Leased Premises, or for
any other reason, or if any such changes, modifications, alterations,
additional sprinkler heads or other equipment become necessary to prevent the
imposition of a penalty or charge against the full allowance for a sprinkler
system in the fire insurance rate as fixed by said Exchange or by any fire
insurance company, Tenant shall, at Tenant's expense, promptly make and supply
such changes, modifications, alterations, additional sprinkler heads or other
equipment.  If Tenant fails to perform such work, Landlord may do so on
Tenant's behalf and at Tenant's cost, and all of Landlord's costs therefore
shall be Additional Rent due hereunder on demand.

         19.00   NOTICE.  In every instance where it shall be necessary or
desirable for Tenant to serve any notice or demand upon Landlord, such notice
or demand shall be sent by United States Registered or Certified Mail, postage
prepaid, addressed to Landlord at the place where Rent under this Lease is then
being paid or such other place as Manager may direct from time to time.  Any
notice or demand to be given by Landlord to Tenant shall be effective if mailed
or delivered by the United States Postal Service or Federal Express or similar
express carrier, postage or charges prepaid or by personal service, to the
Leased Premises, or to such other address as may appear on the records of
Landlord.  Notice mailed as aforesaid shall be conclusively deemed to have been
served at the close of the second





                                     - 22 -
<PAGE>   45
business date following the date said notice was mailed.  Courier or personal
service shall be deemed given upon the date delivered.  In the event of a
conflict in dates, the earlier date of the two above dates shall be considered
the "Notice Date."

         20.00   SUCCESSORS AND ASSIGNS.  Each provision hereof shall extend to
and shall, as the case may require, bind and inure to the benefit of Landlord
and Tenant and their respective heirs, legal representatives, successors and
assigns, provided that this Lease shall not inure to the benefit of any
assignee, heir, legal representative, transferee or successor of Tenant except
upon the prior written consent or election of Landlord, as provided for herein.

         The term "Landlord" as used in this Lease means only the owner of
legal title, or the mortgagee in possession for the time being, of the Property
or of the Tenant's interest in a lease which includes the Property, so that in
the event of the creation of such lease or of any sale of the Property or of
the lessee's interest in said lease which includes the Property, the person or
entity that was Landlord immediately prior to such creation or sale shall be
entirely free and relieved of all covenants and obligations of Landlord
hereunder, and Tenant agrees to look solely to such purchaser or lessee for the
performance of Landlord's obligations hereunder.

         21.00   INSURANCE.  Tenant shall carry insurance during the entire
Term insuring Tenant, Landlord (and, if Landlord so requests, mortgagees of all
or any portion of the Property) and Manager as their interests may appear with
terms, coverages and limits and in companies satisfactory to Landlord, and with
such increases in coverages and limits as Landlord may from time to time
request, but initially Tenant shall maintain the following coverages in the
following amounts:

                 (a)       In case of personal injury to or death of any person
         or persons, and in case of property damage, not less than Three
         Million Dollars ($3,000,000.00) for each occurrence; and

                 (b)       In case of fire, sprinkler leakage, malicious
         mischief, vandalism, and other extended coverage perils, for the full
         insurable replacement value of all additions, improvements and
         alterations to the Leased Premises which are beyond the "Building
         Standard" tenant improvements provided by Landlord and of all office
         furniture trade fixtures, office equipment, merchandise and all other
         items of Tenant's property on the Leased Premises.

Tenant shall, prior to the commencement of the Term and thereafter during the
Term upon request by Landlord, furnish to Landlord certificates evidencing such
coverage, which certificates shall state that such insurance coverage may not
be changed or cancelled without at least thirty (30) days prior written notice
to Landlord and Tenant.

Landlord and Tenant each hereby waive any and every claim for recovery from the
other for any and all loss of or damage to the Property or to the contents
thereof, which loss or damage is covered by valid and collectible fire and
extended coverage insurance policies, to the extent that such loss or damage is
recoverable under said insurance policies.  Inasmuch as this mutual waiver will
preclude the assignment of any such claim by subrogation (or otherwise) to an
insurance company (or any other person), Landlord and Tenant each agree to give
to each insurance company which has issued, or in the future may issue, its
policies of fire and extended coverage insurance, written notice of the terms
of this mutual waiver, and to have said insurance policies properly endorsed,
if necessary, to prevent the invalidation of said insurance coverage by reason
of said waiver.

<PAGE>   46
         22.00   MISCELLANEOUS.

         22.01   FORCE MAJEURE.  Wherever there is provided in this Lease
(including any Riders hereto) a time limitation for performance by Landlord or
Tenant for any construction, repair, maintenance or service, the time provided
for shall be extended for as long as and to the extent that delay in compliance
with such limitation is due to an act of God, strikes, governmental control or
other factors beyond the reasonable control of either Landlord or Tenant as the
case may be.

         22.02   PARTIAL INVALIDITY.  If any provision of this Lease or
application to any party or circumstances shall be determined by any court of
competent jurisdiction to be invalid and unenforceable to any extent, the
remainder of this Lease or the application of such provision to such person or
circumstances, other than those as to which it is so determined invalid or
unenforceable, shall not be affected thereby, and each provision hereof shall
be valid and shall be enforced to the fullest extent permitted by law.

         22.03   HEADINGS.  The headings of sections are for convenience only
and do not define, limit or construe the contents of such sections or
subsections.  References made in this Lease to numbered sections and
subsections shall refer to the numbered sections or subsections of this Lease
unless otherwise indicated.

         22.04   ORIGINALS.  The Lease is to be executed in copies, each of
which executed copy shall constitute an original.  In the event of a conflict
between the provisions of any original Lease with the provisions of any other
original Lease, then in such event the provisions of Landlord's original Lease
will govern and control.

         22.05   EXECUTION OF FURTHER DOCUMENTS.  Tenant agrees at the request
of Landlord to execute such instruments or documents as Landlord may reasonably
request, acknowledging:  the Completion Date; Possession Date; the date of
commencement of Rent; the Commencement Date; the Termination Date; the
Operating Costs and Consumer Price Index for any Year; compliance or
non-compliance by any party with any of the terms or provisions of this Lease;
and to evidence such other or further matters as may be so reasonably
requested.

         22.06   BROKER.  Tenant represents that, except for Manager and that
broker, if any, listed in the Schedule with respect to this Lease, it has not
dealt with any other broker, finder or consultant in connection with this Lease
and, to its knowledge, no broker, finder or consultant other than Manager
initiated or participated in the negotiation of this Lease, submitted or showed
the Leased Premises to Tenant or is entitled to any commission or fee in
connection with this Lease.  Tenant hereby indemnifies, defends, and holds
Landlord and its officers, directors, agents, employees and servants, harmless
from and against any and all claims, liability, cost and expense resulting from
the inaccuracy or breach of the foregoing representations or which they would
not have incurred had the foregoing been true.

         22.07   NO REINSTATEMENT OF LEASE.  No receipt of money by Landlord
from Tenant after the termination of this Lease, the service of any notice, the
commencement of any suit or final judgment for possession shall reinstate,
continue or extend the term of this Lease or affect any such notice, demand,
suit or judgment.

         22.08   NO WAIVER.  No waiver by Landlord of default of Tenant shall
be implied, and no express waiver shall affect any default other than the
default specified in such waiver and that only for the time and to the extent
therein stated.





                                     - 24 -
<PAGE>   47
         22.09   NO OPTION UPON SUBMISSION.  Submission of this instrument for
examination or signature by Tenant does not constitute a reservation of or
option for lease, and it is not effective as a lease or otherwise until
execution and delivery by both Landlord and Tenant.

         22.10   FEES FOR SERVICES.  Nothing in this Lease shall be construed
to prevent Landlord from paying for services rendered or materials delivered
with respect to the Property, Building or to the Leased Premises (including,
without limitation, management services and contracting out capital
improvements or other capital repairs or construction items) by affiliates of
Landlord provided that the fees or costs of such services and materials are at
market rates in the Chicago metropolitan area.  All such fees or costs paid by
Landlord to such affiliates shall be deemed to constitute fees and costs on the
same terms and conditions as if such fees and costs were paid to non-affiliates
of Landlord or its beneficiaries.

         23.00   ESTOPPEL CERTIFICATE.  Tenant agrees that, from time to time
within ten (10) days after request by Landlord, Tenant, or Tenant's duly
authorized representative having knowledge of the following facts, will deliver
to Landlord a statement in writing certifying:  (i) that this Lease is
unmodified and in full force and effect (or if there have been modifications
that the Lease as modified is in full force and effect); (ii) the dates to
which Rent and other charges have been paid; and (iii) that Landlord is not in
default under any provision of this Lease, or, if in default, the nature
thereof in detail, it being intended that any such statement may be relied upon
by any prospective purchaser or tenant of the Property, any mortgagees or
prospective mortgagees thereof, or any prospective assignee of any mortgage
thereof and (iv) such other matters as may be reasonably requested by Landlord.
Tenant shall execute and deliver whatever instruments may be required for such
purposes and, without limitation of Landlord's other rights and remedies or
Tenant's liability for failure so to do, in the event Tenant fails so to do
within ten (10) days after demand in writing, Tenant shall be considered in
default under this Lease.

         24.00   EXERCISE OF LANDLORD'S POWERS.  All determinations which may
be made, actions which may be taken or rights which may be exercised by
Landlord hereunder may be made, taken or exercised by Manager or such other
person or entity specified by Landlord in a notice to Tenant.

         25.00   NO CONSTRUCTION AGAINST DRAFTING PARTY.  Landlord and Tenant
acknowledge that each of them and their counsel have had an opportunity to
review this Lease and that this Lease will not be construed against Landlord
merely because Landlord has prepared it.

         26.00   NO RECORDING.  Tenant's recordation of this Lease or any
memorandum or short form of it will be void and a default under this Lease.

         27.00   LIMITATION ON RECOURSE.  No shareholder or holder of any other
interest in Landlord or Manager shall be personally liable for the performance
of Landlord's obligations under this Lease.  The liability of Landlord or
Manager (including an assignee or successor of Landlord) for Landlord's
obligations under this Lease shall be limited to Landlord's interest in the
Property and Tenant shall not look to any of Landlord's other assets including
Landlord's agent's other assets in seeking either to enforce Landlord's
obligations under this Lease or to satisfy a judgment for Landlord's failure to
perform such obligations.  Neither Landlord nor its agents, directors,
officers, employees, or servants shall be personally liable under this Lease.

         28.00   WAIVER OF JURY TRIAL.  Landlord and Tenant by this section
waive trial by jury in any action, proceeding or counterclaim brought by either
of the parties to this Lease against the other on any matters whatsoever
arising out of or in any way connected with this Lease, the relationship of





                                     - 25 -
<PAGE>   48
Landlord and Tenant, Tenant's use or occupancy of the Leased Premises, or any
other claims (except claims for personal injury or property damage), and any
emergency statutory or any other statutory remedy.

         29.00   NO MERGER.  The voluntary or other surrender of this Lease by
Tenant or the cancellation of this Lease by mutual agreement of Tenant and
Landlord or the termination of this Lease on account of Tenant's default will
not work a merger, and will, at Landlord's option, (a) terminate all or any
subleases and subtenancies, or (b) operate as an assignment to Landlord of all
or any subleases or subtenancies.  Landlord's option under this Section will be
exercised by notice to Tenant and all known sublessees or subtenants of any
part of the Leased Premises.

         30.00   WRITTEN AMENDMENT REQUIRED.  No amendment, alteration,
modification of or addition to the Lease will be valid or binding unless
expressed in writing and signed by Landlord and Tenant.

         31.00   ENTIRE AGREEMENT.  This Lease, the Appendices, Exhibits and
Addenda, if any, contain the entire agreement between Landlord and Tenant and
may be amended only by subsequent written agreement.  No promises or
representations, except as contained in this Lease, have been made to Tenant
respecting the condition of the Leased Premises or the manner of operating the
Building or the Property.

         32.00   AUTHORITY.  Tenant and the party executing this Lease on
behalf of Tenant represent to Landlord that such party is authorized to do so
by requisite action of the board of directors, or partners, as the case may be,
and agree upon request to deliver to Landlord a resolution or similar document
to that effect.

         33.00   GOVERNING LAW AND VENUE.  This Lease will be governed by and
construed pursuant to the laws of the State of Illinois.  Venue in any action
arising out of this Lease will be proper only in the Circuit Court of DuPage
County, Illinois or the United States District Court for the Northern District

         34.00   BINDING EFFECT.  The covenants, conditions and agreements
contained in this Lease will bind and inure to the benefit of Landlord and
Tenant and their respective heirs, distributees, executors, administrators,
successors, and, except as otherwise provided in this Lease, their assigns.

         35.00   ENERGY CONSERVATION.  Notwithstanding anything to the contrary
in this Lease, Landlord shall have the right to institute such policies,
programs and measures as may be necessary or desirable, in Landlord's
discretion, for the conservation and preservation of energy or energy related
services, or as may be required to comply with any applicable codes, rules and
requirements, whether mandatory or voluntary.

         36.00   MORTGAGE OR GROUND LEASE BY LANDLORD.  Tenant hereby agrees
this Lease shall automatically be subject and subordinate to (i) any mortgage
that may hereafter by placed upon the Property and to all amounts secured
thereby and (ii) to any ground lease of the Land and Property, or either, and
to all renewals, replacements and extensions of any of the foregoing, except to
the extent that any such mortgage or ground lease provides otherwise.  Tenant
further agrees that, in the event of a foreclosure of any such mortgage or of a
conveyance in lieu thereof or of a termination of any such lease, it will
attorn to the mortgagee or to the purchaser at any foreclosure sale or to the
ground lessor, as the case may be, upon the condition that the mortgagee or
ground lessor, as the case may be, shall agree in writing delivered to Tenant
that such mortgagee or any purchaser at a foreclosure sale or such ground





                                     - 26 -

lessor will recognize Tenant and this Lease in the event such party acquires
the Property, so long as Tenant is not then in default.  Tenant shall at
Landlord's request execute such further instruments or assurances as the
mortgagee or ground lessor may reasonably request to evidence the subordination
of this Lease or to acknowledge the superiority of this Lease, as the case may
be, and Tenant's attornment agreement.

         37.00   OPTION TO RENEW.  Option to Renew.  Provided that the Lease is
then in full force and effect and provided further that Tenant is then
occupying all the leased premises having been leased to the Tenant in Commerce
Plaza, the Landlord hereby grants to Tenant an option to renew the Lease (the
"Option to Renew"), on the same terms and conditions set forth in the Lease,
except as set forth below, for one (1) additional five (5) year term (the
"Option Period").  Tenant's right to exercise the Option to Renew shall be
conditioned upon (a) Landlord's receipt, no later than one hundred and twenty
(120) days prior to the termination date of the Lease of Tenant's then current
certified financial statements showing a creditworthiness satisfactory to
Landlord, and (b) Tenant's written certification to Landlord that at all times
during the term of the Lease and prior to Tenant's exercise of the Option to
Renew there have been no material adverse changes in the financial condition of
Tenant as reflected in said certified financial statements.  The Option to
Renew shall be exercised, if at all, by written notice received by Landlord not
later than twelve (12) months prior to the termination date, time being of the
essence.  If not so exercised, Tenant shall have no further Option to Renew the
Lease.  The annual base rent for the year during the Option Period shall be the
market rate, at the time the Option to Renew is exercised, for the leasing of
comparable space in buildings comparable to Commerce Plaza in the Oak Brook,
Illinois area for a term equal to the Option Period and commencing at
approximately the date of the commencement of the Option Period, but in no
event shall the base rent for any year of the Option Period be less than the
base rent in effect for the last year of the term.  Landlord shall have no
obligation to make improvements, decorations, repairs, alterations, or
additions to the leased premises as a condition to the Tenant's obligation to
pay base rent for the Option Period, and base rent quoted by Landlord for the
Option Period shall not be reduced (a) by reason of such fact, (b) to take into
account any rental concessions whatsoever (including, but not limited to rent
abatements, allowances for moving expenses, lease assumptions, or other
concessions), or (c) to take into account the absence of any cost or expense
which Landlord would have incurred had the leased premises been leased to a
person or entity other than Tenant.  Landlord's good faith determination of the
base rent for the Option Period shall be conclusive, provided, however, Tenant
shall have the right to nullify its exercise of the Option to Renew, by notice
to Landlord, given within thirty (30) days of Landlord's notice to Tenant
(which Landlord's notice shall be given to Tenant not later than eleven (11)
months prior to the commencement of the Option Period) setting forth the
initial base rent for the Option Period, in which event Tenant's exercise of
the Option to Renew shall be null and void and neither Landlord nor Tenant
shall have any further rights or liabilities with respect thereto.  Tenant's
failure to give the notice of nullification described above within such thirty
(30) day period shall constitute acceptance by tenant of, and Tenant's
agreement to pay, the base rent specified for the Option Period.

         38.00   ALLOWANCE.  Landlord and Tenant hereby agree that Landlord
shall provide to Tenant an allowance equal to One Hundred Twenty-Three Thousand
Four Hundred Seventy-Three and No/100 Dollars ($123,473.00), subject to the
terms and conditions as provided in Appendix D - Tenant Improvement Work
Agreement.  Such allowance should be used toward the construction of Tenant's
interior tenant improvements.  Any portion of the allowance not used by Tenant
for the Work to be performed under the terms and conditions as set forth in the
Tenant Improvement Work Agreement may be used by Tenant to pay the costs of
space planning and moving costs.  Notwithstanding anything contained herein to
the contrary, the amount of the allowance described in this Section 38.00 which
may be used for space planning and moving shall be limited to an amount not to
exceed Eleven Thousand Nine Hundred Forty-Nine and No/100 Dollars ($11,949.00).

         39.00   PARKING.  Landlord agrees to furnish to Tenant during the term
of the Lease up to six (6) parking stalls in the Landlord's underground garage
area for the use of its employee(s).  Three (3) of the underground stalls will
be at no charge to Tenant.  The charge for the remaining three (3) underground
stalls will be at the rate charged other tenants which presently is $60.00 per
month per stall.  Tenant agrees to abide by Landlord's normal rules and
regulations as they apply to the underground garage.

         40.00   RIGHT OF FIRST OFFER.  Providing Tenant is not in default, the
Lease is in full force and effect and Tenant is then occupying all the premises
having been leased to the Tenant in the Building, Tenant shall have the right
of first offer on up to an additional contiguous 5,000 rentable square feet to
the Leased Premises the first time that said space becomes vacant and
accordingly available for leasing to third parties during the period from the
Commencement Date until May 31, 1996 (the "Expansion Space").  The right of
first offer is subject and subordinate to the rights of existing tenants of the
Building under contracts in effect as of the date hereof, and to Landlord's
right to lease any portion of the Expansion Space one time to parties other
than Tenant, including Metropolitan Life Insurance Company or any of its
subsidiaries.  Landlord shall deliver to Tenant promptly after Landlord learns
of the same, written notice specifying when the Expansion Space will become
available.  Within five (5) days thereafter, Tenant shall give written notice
to Landlord of its intention to accept Landlord's offer to lease the Expansion
Space and, within thirty (30) days thereafter, Tenant shall enter into a Lease
Amendment acknowledging Tenant's acceptance of the Expansion Space on the same
terms and conditions set forth in this Lease except that the rental rate shall
be adjusted for escalations in effect for Tenant at the time of the
commencement of such Lease Amendment.  The Expansion Space shall be accepted
"as is" and Tenant shall bear the cost of constructing any required demising
walls.  In the event Tenant declines to accept Landlord's offer to lease the
Expansion Space, or does not provide written acceptance thereof or enter into
the Lease Amendment within the time limits set forth above, then the right of
first offer granted herein shall terminate, and Landlord shall be free to enter
into a new lease or leases with third parties for all or any portion of the
Expansion Space on such terms as Landlord shall deem appropriate in its sole
discretion.

         IN WITNESS WHEREOF, this instrument has been duly executed by the
parties hereto as of the date the Lease was signed by Manager for Landlord as
listed below.

                                      apply to any Operating Costs which do not
                                      vary with the amount of occupancy in the
                                      Property.

                                      In the event Landlord does not purchase
                                      for any Year insurance covering one or

                                      Landlord would have been required to pay
                                      to obtain such insurance with a
                                      recognized carrier for such year and such

                                      Year or Period as determined by Landlord

                                      Judgment without regard to when such

                          with each application for payment.  Contractor further
                          expressly undertakes to indemnify, defend and hold
                          harmless Landlord, at Contractor's sole expense,
                          against any actions, lawsuits, or proceedings brought
                          against Landlord as a result of




                                      -3-
<PAGE>   67
                          liens or claim of lien and agrees to pay any
                          judgement or lien against Landlord or Landlord's
                          property resulting from any such actions, lawsuits or

                          mechanic lien claims by payment to the mechanic lien
                          claimant if Landlord in its sole discretion deems
                          such payment to be the most economical method of
                          sending the dispute, and Landlord may thereafter
                          deduct the payment from future amounts due Contractor
                          or require Contractor pay said amounts to Landlord
                          upon demand.

                          affect the fire alarm system.  If it is determined
                          that such demolition and/or construction work may
                          trigger the fire alarm system, the Contractor shall
                          notify the Building Engineer.

                          overnight, on weekends or on holidays.  Twenty-four
                          hour written notice will be provided by Contractor
                          prior to removing the fire alarm system from service.

                          As part of any shift down of the fire alarm system,
                          Contractor will comply with any procedures or
                          requirements that the Building Engineer may

                          notify the Building Engineer when protection is in
                          place so they may be verified prior to undertaking
                          such activities.

            4.03          The Contractor will refill the sprinkler system at
                          the end of the day when the work is done on a build
                          out and occupied floor.  The Contractor will refill
                          the sprinkler system for the Base Building cores on
                          all vacant floors at the end of the day.  The
                          Contractor will contact the Building Engineer before
                          refilling.  After refilling the system the Contractor
                          will remain on-site to verify that no leaks occur
                          after the pressure is back to normal.

            4.04          The Contractor will notify the Project Manager one
                          week before any electrical shutdowns which might

                          portions of the Property.

            4.05          The Contractor will provide an adequate number of
                          fire extinguishers in the work area throughout the

     3.  Lease Term. This Lease shall continue in force during a period

     5.  Base Rental.

         (a)  Tenant agrees to pay to Landlord during the Lease Term, without
any setoff or deduction whatsoever, the Base Rental and all such other sums of
money as shall become due hereunder as additional rent, all of which are
sometimes herein collectively called "rent", for the nonpayment of which
Landlord shall be entitled to exercise all such rights and remedies as are
herein provided in the case of the nonpayment of Base Rental. The Base Rental,
together with any estimated adjustments thereto pursuant to Paragraphs 6, 19,
20, and 28 hereof and pursuant to any other provision of this Lease, shall be
due and payable in advance in monthly installments as shown on the Base Rental
Schedule attached hereto on the first day of each calendar month during the
Lease Term except as the first month's Base Rental may have been paid with the
execution hereof, and Tenant hereby agrees to pay such Base Rental and any
adjustments thereto to Landlord at Landlord's address provided herein (or such
other address in Tulsa County as may be designated by Landlord in writing from
time to time) monthly, in advance, and without demand.

         (b)  In the event all or any part of any installment of rent is not
paid when due and payable, Landlord may at its sole option require Tenant to
pay a late payment fee of $100.00. In addition, an interest charge shall accrue
on the delinquent rent at one and one-half percent (1 1/2%) per month.

         (c)  In the event any installment of rent paid by check is returned to
the Landlord because of insufficient funds, Tenant shall pay to Landlord as
rent on demand a returned check charge fee of $50.00.

     6.  Basic Cost Increase Adjustment. The Base Rental payable hereunder
shall be adjusted upward (but not downward) from time to time in accordance
with the following provisions:

         (a)  The Building contains approximately 321,500 square feet of Net
Rentable Area in aggregate. Tenant's Base Rental is based, in part, upon the
estimate that during each calendar year of the Lease Term, Basic Costs will be
equal to the actual Basic Costs for the calendar year 1993 (such estimate on a
square foot of Net Rentable Area in the Building basis being hereafter referred
to as the "Expense Stop").  Tenant shall, when Landlord so requires, during the
Lease Term pay as an adjustment to Base Rental hereunder an amount (per each
square foot of Net Rentable Area of the Premises, including those portions of
Common Areas allocated to the Premises from time to time) equal to the excess
("Excess") from time to time of actual Basic Costs per square foot of Net
Rentable Area in the Building over the amount of the Expense Stop.  Landlord
may collect such additional Base Rental in arrears on a yearly basis. Landlord
shall also have the option to make a good faith estimate of the Excess for each
upcoming calendar year and upon thirty (30) days' written notice to Tenant may
adjust the monthly




                                       3
<PAGE>   4

payment of Base Rental in the then current year in accordance with such
estimate. Any amounts paid based on such an estimate shall be subject to
adjustment pursuant to Paragraph 6(b) when actual Basic Costs are available for
each calendar year.

         (b)  Tenant, at its expense, shall have the right, no more frequently
than once per calendar year, following prior written notice to Landlord, to
audit, at Tenant's sole expense, Landlord's books and records relating to Basic
Costs incurred during the calendar year preceding such audit. In the event such
an audit demonstrates that additional Base Rental collected for such preceding
year and attributable to any Excess to be higher or lower than the amount of
additional rental actually due pursuant to subparagraph 6(a) above, then, if
higher, Landlord may at Landlord's discretion, apply any over-payment to the
estimate described in the next to the last sentence in the preceding paragraph
or apply any over-payment in equal installments to the monthly Base Rental for
the remainder of the then current calendar year or, if lower, Tenant shall pay
to Landlord any under-payment within ten (10) days of such determination.

         (c)  Notwithstanding anything to the contrary contained herein,
Landlord and Tenant agree that for the months of October, November, and
December, 1994, Tenant shall pay to Landlord, in lieu of adjustment of Base
Rental under the terms of subparagraph 6(a) above, the sum of $85.83 in each of
said three months as an adjustment to the installment of Base Rental for each
of said three months and shall be payable at the same time and on the same
terms as the installment of Base Rental for each of said three months is
otherwise payable. This provisions of this subparagraph 6(c) shall not alter or
affect in any way the adjustment of Base Rental pursuant to the provisions of
subparagraph 6(a) hereof except for the calendar year 1994.

     7. Services to be Furnished by Landlord. Landlord agrees to furnish Tenant
the following services:

         (a)  Hot and cold water at those points of supply provided for general
use of tenants in the Building on the floor(s) on which the Premises are

          (c)  If Tenant's consumption of electrical services exceeds either
the rated capacities and/or design loads as per subparagraphs 13(a) and 13(b),
or generates heat in excess of that Landlord's air conditioning system is
designed to handle, then Tenant shall remove such equipment and/or lighting to
achieve compliance within ten (10) days after receiving notice from Landlord
or, upon receiving Landlord's prior written approval, such equipment and/or
lighting may remain in the Premises, subject to the following:

               (i)  Tenant shall pay for all costs of installation and
maintenance of submeters, wiring, additional air conditioning systems and other
items required by Landlord, in Landlord's discretion, to accommodate Tenant's
excess design loads and capacities or heat generation.

                                       5
<PAGE>   6
               (ii)  Tenant shall reimburse to Landlord, upon demand, the cost
of the excess demand and consumption of electrical service at rates charged to
Landlord (which rates shall be in accordance with any applicable laws) as well
as all costs of operating additional air conditioning systems deemed necessary
by Landlord on account of Tenant's excess consumption and/or heat generation.

               (iii)  Landlord may, at its option, upon not less than thirty
(30) days' prior written notice to Tenant, discontinue the availability of such
extraordinary utility service and/or air conditioning service. If Landlord
gives any such notice, Tenant will contract directly with such public utility
at Tenant's cost for the supplying of such utility service to the Premises.

     14.  Laws and Requlations. Tenant agrees to comply with all applicable
laws, ordinances, rules and regulations of any governmental entity or agency
having jurisdiction of the Premises.

     15.  Building Rules. Tenant will comply with the rules of the Building and
the Project adopted and altered by Landlord from time to time and will cause
all of its agents, employees, invitees and visitors to do so; all changes to
such rules will be sent by Landlord to Tenant in writing. The initial rules for
the Project are attached hereto as Exhibit "D" and made a part hereof.

     16.  Entry by Landlord. Tenant agrees to permit Landlord or its agents or
representatives to enter into and upon all or any part of the Premises or to
the Building at all reasonable hours (and in emergencies at all times) to
inspect the same, to show the Premises to prospective purchasers, mortgagees,
tenants or insurers, or to clean or make repairs, alterations or additions
thereto or to the Building or Project, and Tenant shall not be entitled to any
abatement or reduction of rent by reason thereof.

     17.  Assignment and Subletting.

          (a)  Tenant shall not assign, sublease, transfer, sell or encumber
this Lease or any interest therein. Any attempted assignment, sublease,
transfer, sale, or encumbrance by Tenant in violation of the term and covenants
of this paragraph shall be void.

          (b)  All cash or other proceeds of any assignment, sublease,
transfer, or sale of Tenant's interest in this Lease, whether consented to by
Landlord or not, shall be paid to Landlord, notwithstanding the fact that such
proceeds exceed the rentals called for hereunder, unless Landlord agrees to the
contrary in advance in writing, and Tenant hereby assigns to Landlord all
rights it might have or ever acquire in any such proceeds. This covenant and
assignment shall run with the land and shall bind Tenant and Tenant's heirs,
executors, administrators, personal representatives, successors and assigns.
Any assignee, sublessee, transferee, or purchaser of Tenant's interest in this
Lease (all such assignees, sublessees, transferees, and purchasers being
hereinafter referred to as "Successors"), by assuming Tenant's obligations
hereunder, shall assume liability to Landlord for all amounts paid to persons
other than Landlord by such Successor in consideration of any such assignment,
subletting, transfer, or sale in violation of the provisions hereof. In no
event shall such assignment, subletting, transfer, or sale relieve Tenant of
liability for any obligation hereunder, regardless of whether any assignee,
sublessee, transferee, or purchaser assumes Tenant's liability hereunder and
regardless of whether such assignment, subletting, transfer, or sale is
approved by Landlord.

     18.  Mechanic's Liens. Tenant will not permit any mechanic's or
materialman's lien or liens to be placed upon the Premises, the Building, or
the Project and nothing in this Lease shall be deemed or construed in anyway as
constituting the consent or request of

                                      6
<PAGE>   7

Landlord, express or implied, by inference or otherwise, to any person for the
performance of any labor or the furnishing of any materials to the Premises,
the Building, or the Project, or any part thereof, nor as giving Tenant any
right, power, or authority to contract for or permit the rendering of any
services or the furnishing of any materials that would give rise to any
mechanic's, materialman's, or other liens against the Premises. In the event
any such lien is attached to the Premises, then, in addition to any other right
or remedy of Landlord, Landlord may, but shall not be obligated to, discharge
the same. Any amount paid by Landlord for any of the aforesaid purposes shall
be paid by Tenant to Landlord on demand as additional rent.

     19.  Insurance.

          (a)  Landlord shall maintain fire and extended coverage insurance on
the Building and the Premises in such amounts as the Building's mortgagees
shall require payable solely to Landlord or the mortgagees of the Building as
their interests shall appear. Tenant shall maintain at its expense, in an
amount equal to full replacement cost, fire and extended coverage insurance on
all of its personal property, including removable trade fixtures, located in
the Premises and in such additional amounts as are required to meet Tenant's
obligations pursuant to subparagraph 23 hereof. Tenant's insurance pursuant to
the provisions of subparagraphs 19(a) and 19(b) hereof shall provide that such
insurance may not be cancelled or expire without at least thirty (30) days'
prior written notice to Landlord from the insurer. All policies of insurance
required of Tenant under this Lease and representing the coverages and
conditions required by any provision of this Lease (including without
limitation subparagraphs 19(a) and 19(b) and Paragraph 22) shall contain an
endorsement requiring thirty (30) days' prior written notice to Landlord before
cancellation, termination or change in the coverage, scope, amount, or
conditions of any such policy.  Each such policy, or a certificate thereof
evidencing to Landlord's satisfaction such coverages and conditions, together
with evidence of payment of premiums, shall be deposited with Landlord at the
commencement of the Lease Term, and on renewal of the policy not less than
thirty (30) days before expiration of the term of the policy.

          (b)  Each of Tenant and Landlord shall, each at its own expense,
except Landlord's policy premiums shall be included in Basic Costs, maintain a
policy or policies of comprehensive general liability insurance with respect to
the respective activities of each in the Building with the premiums thereon
fully paid on or before due date, issued by and binding upon an insurance
company approved by Landlord, such insurance to afford minimum protection of
not less than $1,000,000 combined single limit coverage of bodily injury,
property damage or combination thereof. Landlord shall be named as an
additional insured on Tenant's insurance required by this subparagraph l9(b).
Landlord shall not be required to maintain insurance against thefts within the
Premises, the Building or the Project generally.

     20.  Property Taxes.  Landlord agrees (subject to the provisions of
Paragraph 6 hereof) to pay all ad valorem taxes levied against the Project, but
Tenant shall be liable for all taxes levied against personal property and trade
fixtures placed by Tenant in the Premises.  If any taxes for which Tenant is
liable under this Paragraph are levied against Landlord or Landlord's property
and if Landlord elects to pay the same or if the assessed value of Landlord's
property is increased by inclusion of personal property and trade fixtures
placed by Tenant in the Premises and Landlord elects to pay the taxes based on
such increase, Tenant shall pay to Landlord upon demand that part of such taxes
for which Tenant is liable hereunder.

     21.  Indemnity. Landlord and its officers, agents, managers, and employees
shall not be liable to Tenant, or to Tenant's agents,

                                      7
<PAGE>   8

servants, employees, customers, or invitees for any injury to person or damage
to property, including without limitation liability for consequential damages,
caused by any act, omission, or neglect of Tenant, its agents, servants, or
employees, invitees, licensees or any other person entering the Project under
the invitation of Tenant or arising out of the use of the Premises by Tenant
and the conduct of its business or out of a default by Tenant in the
performance of its obligations hereunder. Tenant hereby indemnifies and holds
Landlord and its officers, agents, managers, and employees harmless from all
liability and claims for or resulting from any such damage or injury.

     22.  Waiver of Subrogation Rights. Anything in this Lease to the contrary
notwithstanding, Landlord and Tenant each hereby waives any and all rights of
recovery, claim, action, or cause of action, against the other, its agents,
officers, managers, or employees, for any loss or damage that may occur to the
Premises, or any improvements thereto, or the Building or the Project, or any
improvements thereto, or any personal property of such party therein, by reason
of fire, the elements, or any other cause(s) which are insured against under
the terms of the standard fire and extended coverage insurance policies
referred to in Paragraph 19 hereof, regardless of cause or origin, including
negligence of the other party hereto, its agents, officers, managers, or
employees.

     23.  Casualty Damage. If the Premises or any part thereof shall be damaged
by fire or other casualty, Tenant shall give prompt written notice thereof to
Landlord. In case the Building shall be so damaged that substantial alteration
or reconstruction of the Building shall, in Landlord's sole opinion, be
required (whether or not the Premises shall have been damaged by such casualty)
or in the event any mortgagee of the Building should require that the insurance
proceeds payable as a result of a casualty be applied to the payment of the
mortgage debt or in the event of any material uninsured loss to the Building,
Landlord may, at its option, terminate this Lease by notifying Tenant in
writing of such termination within ninety (90) days after the date of such
damage. If Landlord does not thus elect to terminate this Lease, Landlord shall
commence and proceed with reasonable diligence to restore the Building to
substantially the same condition in which it was immediately prior to the
happening of the casualty, except that Landlord's obligation to restore shall
not exceed the scope of the work required to be done by Landlord at Landlord's
expense in originally constructing the Building and installing the Tenant
Improvements, nor shall Landlord be required to spend for such work an amount
in excess of the insurance proceeds actually received by Landlord as a result
of the casualty. When the portions of the Premises originally furnished at
Landlord's expense have been restored by Landlord, Tenant shall, at Tenant's
expense, complete the restoration of the Premises, including the reconstruction
of all improvements in excess of those Tenant Improvements originally installed
at Landlord's expense, and the restoration of Tenant's furniture and equipment.
Landlord shall not be liable for any inconvenience or annoyance to Tenant or
injury to the business of Tenant resulting in any way from such damage or the
repair thereof, except that, subject to the provisions of the next sentence,
Landlord shall allow Tenant a fair diminution of rent during the time and to
the extent the Premises are unfit for occupancy. If the Premises or any other
portion of the Building or the Project be damaged by fire or other casualty
resulting from the fault or negligence of Tenant or any of Tenant's agents,
employees, or invitees, the rent hereunder shall not be diminished during the
repair of such damage and Tenant shall be liable to Landlord for the cost of
the repair and restoration of the Building or the Project caused thereby to the
extent such cost and expense is not covered by insurance proceeds.

     24.  Condemnation. If the whole or substantially the whole of the Building
or the Premises should be taken for any public or quasi-public use, by right of
eminent domain or otherwise, or

                                      8
<PAGE>   9

should be sold in lieu of condemnation, then this Lease shall terminate as of
the date when physical possession of the Building or the Premises is taken by
the condemning authority. If less than the whole or substantially the whole of
the Building or the Premises is thus taken or sold, Landlord (whether or not
the Premises are affected thereby) may terminate this Lease by giving written
notice thereof to Tenant; in which event, this Lease shall terminate as of the
date when physical possession of such portion of the Building or Premises is
taken by the condemning authority. If this Lease is not so terminated upon any
such taking or sale, the Base Rental payable hereunder shall be diminished by
an equitable amount, and Landlord shall, to the extent Landlord deems feasible,
restore the Building and the Premises to substantially their former condition,
but such work shall not exceed the scope of the work done by Landlord in
originally constructing the Building and the Tenant Improvements, nor shall
Landlord in any event be required to spend for such work an amount in excess of
the amount received by Landlord as compensation for such taking. All amounts
awarded upon a taking of any part or all of the Building or the Premises shall
belong to Landlord, and Tenant shall not be entitled to, and expressly waives
all claim to, any such compensation.

     25.  Damages From Certain Causes. Landlord shall not be liable to Tenant
for any loss or damage to any property or person occasioned by theft, fire, act
of God, public enemy, injunction, riot, strike, insurrection, war, court order,
requisition, or order of governmental body or authority or by any other cause
beyond the control of Landlord.  Nor shall Landlord be liable for any damage or
inconvenience which may arise through repair or alteration of any part of the
Building, the Project, or the Premises.

     26.  Events of Default/Remedies.

          (a)  The following events shall be deemed to be events of default by
Tenant under this Lease: (i) Tenant shall fail to comply with any provision of
this Lease or any other agreement between Landlord and Tenant all of which
terms, provisions and covenants shall be deemed material; (ii) the leasehold
hereunder demised shall be taken on execution or other process of law in any
action against Tenant; (iii) Tenant shall fail to promptly move into and take
possession of the Premises when the Premises are ready for occupancy or shall
cease to do business in or abandon any substantial portion of the Premises;
(iv) Tenant shall become insolvent or unable to pay its debts as they become
due, or Tenant notifies Landlord that it anticipates either condition; (v)
Tenant takes any action to, or notifies Landlord that Tenant intends to file a
petition under any section or chapter of the United States Bankruptcy Code, as
amended, or under any similar law or statute of the United States or any State
thereof; or a petition shall be filed against Tenant under any such statute or
Tenant or any creditor of Tenant's notifies Landlord that it knows such a
petition will be filed or Tenant notifies Landlord that it expects such a
petition to be filed; or (vi) a receiver or trustee shall be appointed for
Tenant's leasehold interest in the Premises or for all or a substantial part of
the assets of Tenant.

          (b)  If Tenant does not make payment when due of any rental
installment required of Tenant in the Lease, or if default by Tenant under this
Lease otherwise occurs, in addition to the imposition of appropriate late
charges, Landlord may, at its option, declare the total Base Rental due or to
be due under this Lease immediately due and payable and, upon such declaration,
if the same is not paid upon demand, said total Base Rental shall be past due,
delinquent, and in default.

          (c)  If Tenant does not make payment when due of any rental
installment, Tenant waives notice of rent due and demand for payment of said
unpaid installment and waives notice and demand by Landlord for the Tenant to
quit and vacate the Premises if such rent not be paid.

                                      9
<PAGE>   10

          (d)  Upon the occurrence of any event or events of default by Tenant,
whether enumerated in this Paragraph 26 or not, Landlord shall have the option
to pursue any one or more of the following remedies without any notice or
demand for possession whatsoever (and without limiting the generality of the
foregoing), Tenant hereby specifically waives notice and demand for payment of
rent or other obligations due and waives any and all other notices or demand
requirements imposed by applicable law): (i) terminate this Lease in which
event Tenant shall immediately surrender the Premises to Landlord; (ii)
terminate Tenant's right to occupy the Premises and re-enter and take
possession of the Premises (without terminating this Lease but without
prejudice to later termination for the same or other default by Tenant); (iii)
enter upon the Premises and do whatever Tenant is obligated to do under the
terms of this Lease; and Tenant further agrees that Landlord shall not be
liable for any damages resulting to the Tenant from such action; and (iv)
exercise all other remedies available to Landlord at law or in equity,
including, without limitation, injunctive relief of all varieties. No re-entry
or taking possession of the Premises by Landlord shall be construed as an
election by Landlord to terminate this Lease unless a written notice of such
election be delivered by landlord to Tenant.

          (e)  In the event Landlord elects to re-enter or take possession of
the Premises after Tenant's default, Tenant hereby waives notice of such
re-entry or repossession and of Landlord's intent to re-enter or take
possession. Landlord may, without prejudice to any other remedy which he may
have for possession or arrearages in rent, expel or remove Tenant any other
persons who may be occupying said Premises or any part thereof. In addition,
the provisions of Paragraph 29 hereof shall apply with respect to the period
from and after the giving of notice of such election to Tenant. All Landlord's
remedies shall be cumulative and not exclusive. Forbearance by Landlord to
enforce one or more of the remedies herein provided upon an event of default
shall not be deemed or construed to constitute a waiver of such default or a
waiver of Landlord's right to invoke additional remedies for the same or other
defaults.

          (f)  This Paragraph 26 shall be enforceable to the maximum extent not
prohibited by applicable law, and the unenforceability of any portion thereof
shall not thereby render unenforceable any other portion. To the extent any
provision of applicable law requires some action by Landlord to evidence or
effect the termination of this Lease or to evidence the termination of Tenant's
right of occupancy, Tenant and Landlord hereby agree that notice, either oral
or by telephone, or by any act of Landlord that comes to the attention of
Tenant, its agents, servants, or employees, which reflects Landlord's
intention to terminate, shall be sufficient to evidence and effect the
termination herein provided for, but Tenant hereby agrees that, as between
Landlord and Tenant, its successors and assigns, no such notice shall ever be
necessary to effect a termination hereunder.

          (g)  Landlord shall be in default hereunder in the event Landlord has
not begun and pursued with reasonable diligence the cure of any failure of
Landlord to meet its obligations hereunder within thirty (30) days of the
receipt by Landlord of written notice from Tenant of the alleged failure to
perform. In no event shall Tenant have the right to terminate or rescind this
Lease as a result of Landlord's default as to any covenant or agreement
contained in this Lease or as a result of the breach of any promise or
inducement hereof, whether in this Lease or elsewhere. Tenant hereby waives
such remedies of termination and rescission and hereby agrees that Tenant's
remedies for default hereunder and for breach of any promise or inducement
shall be limited to a suit for damages and/or injunction. In addition, Tenant
hereby covenants that, prior to the exercise of any such remedies, it will give
the mortgagees holding mortgages on the Building notice and a reasonable time
to cure any default by Landlord.

<PAGE>   11
    27. Peaceful Enjoyment. Tenant shall, and may peacefully have, hold, and
enjoy the Premises, subject to other terms hereof, provided that Tenant pays
the rent and other sums herein recited to be paid by Tenant and performs all of
Tenant's covenants and agreements herein contained.  This covenant and any and
all other covenants of Landlord shall be binding upon each of Landlord and its
successors only with respect to breaches occurring during the respective
periods of ownership of each of the landlords' interest hereunder.

    28. Consumer Price Index Adjustment. Intentionally omitted

    29. Holding Over. In the event of holding over by Tenant after expiration
or other termination of this Lease, or in the event Tenant continues to occupy
the Premises after the termination of Tenant's right of possession pursuant to
Paragraph 26 (d)(ii) hereof, Tenant shall, throughout the entire holdover
period, pay rent equal on a per diem basis to twice the Base Rental and
additional Base Rental which would have been applicable had the term of this
Lease continued through the period of such holding over by Tenant. No holding
over by Tenant after the expiration of the Lease Term shall be construed to
extend the term of the Lease. The provision of this paragraph shall not be in
place of or in lieu of, but shall be in addition to, the provisions of
subparagraphs 26(a), 26(d), and 26(e).

    30. Subordination to Mortgaged.  Tenant accepts this Lease subject and
subordinate to any mortgage, deed of trust or other lien presently existing or
hereafter arising upon the Premises, upon the Building or upon the Project as a
whole, and to any renewals, refinancing and extensions thereof, but Tenant
agrees that any such mortgagee shall have the right at any time to subordinate
such mortgage, deed of trust or other lien to this Lease on such terms and
subject to such conditions as such mortgagee may deem appropriate in its
discretion. Landlord is hereby irrevocably vested with full power and authority
to subordinate this Lease to any mortgage, deed of trust or other lien now
existing or hereafter placed upon the Premises, the Building or the Project as
a whole, and Tenant agrees upon demand to execute such further instruments
subordinating this Lease or attorning to the holder of any such liens as
Landlord may request. The terms of this Lease are subject to approval by the
Building's permanent lender(s), and such approval is a condition precedent to
Landlord's obligations hereunder. In the event that Tenant should fail to
execute any instrument of subordination herein required to be executed by
Tenant promptly as requested, Tenant hereby irrevocably constitutes Landlord as
its attorney-in-fact to execute such instrument in Tenant's name, place and
stead, it being agreed that such power is one coupled with an interest. Tenant
agrees that it will from time to time upon request by Landlord execute and
deliver to such persons as Landlord shall request a statement in recordable
form certifying that this Lease is unmodified and in full force and effect (or
if there have been modifications, that the same is in full force and effect as
so modified), stating the dates to which rent and other charges payable under
this lease have been paid, stating that Landlord is not in default hereunder
(or if Tenant alleges a default stating the nature of such alleged default) and
further stating such other matters as Landlord shall reasonably require.

    31. Landlord's Lien. Tenant hereby grants to Landlord a lien and security
interest on all equipment, goods, furniture, fixtures, and inventory of Tenant
now or hereafter placed in or upon the Premises and the proceeds thereof, and
such property shall thereafter, wherever located, be and remain subject to such
lien and security interest of Landlord for payment of all rent and other sums
agreed to be paid by Tenant herein. The provisions of this paragraph relating
to such lien and security interest shall constitute a security agreement under
and subject to the Oklahoma Uniform Commercial Code so that Landlord shall have
and may enforce

                                       12
<PAGE>   12

a security interest on all such property of Tenant now or hereafter placed in
or on the Premises, in addition to and cumulative of the Landlord's liens and
rights provided by law or by the other terms and provisions of this Lease.
Tenant agrees to execute as debtor such financing statement or statements as
Landlord may now or hereafter request. Landlord may at its election at any time
file a copy of this Lease as a financing statement.  Notwithstanding the
above, Landlord shall neither sell nor withhold from Tenant, Tenant's business
records.

    32. Attorney's Fees. In the event either party defaults in the performance
of any of the terms of this Lease and the other party employs an attorney in
connection therewith, the defaulting party agrees to pay the other party's
reasonable attorney's fees.

    33. No Implied Waiver. The failure of Landlord to insist at any time upon
the strict performance of any covenant or agreement of this Lease or to
exercise any option, right, power or remedy contained in this Lease shall not
be construed as a waiver or a relinquishment thereof for the future. No payment
by Tenant or receipt by Landlord of a lesser amount than the monthly
installment of rent due under this Lease shall be deemed to be other than on
account of the earliest rent due hereunder, nor shall any endorsement or
statement on any check or any letter accompanying any check or payment of rent
be deemed an accord and satisfaction, and Landlord may accept such check or
payment without prejudice to Landlord's right to recover the balance of such
rent or pursue any other remedy in this Lease provided.

    34. Personal Liability. The liability of Landlord to Tenant for any default
by Landlord under the terms of this Lease shall be limited to the interest of
Landlord in the Project and Tenant agrees to look solely to Landlord's interest
in the Project for the recovery of any judgment from the Landlord, it being
intended that Landlord shall not be personally liable for any judgment or
deficiency.

    35. Security Deposit. The Security Deposit shall be held by Landlord
without liability for interest and as security for the performance by Tenant of
Tenant's covenants and obligations under this Lease, it being expressly
understood that the Security Deposit shall not be considered an advance payment
or rental or a measure of Tenant's damages in case of default by Tenant. Unless
otherwise provided by mandatory nonwaivable law or regulation, Landlord may
commingle the Security Deposit with Landlord's other funds. Landlord may, from
time to time, without prejudice to any other remedy, use the Security Deposit
to the extent necessary to make good any arrearages of rent or to satisfy any
other covenant or obligation of Tenant hereunder. Following any such
application of all or any part of the Security Deposit, Tenant shall pay to
Landlord on demand the amount so applied in order to restore the Security
Deposit to its original amount. If Tenant is not in default at the termination
of this Lease, the balance of the Security Deposit remaining after any such
application shall be returned by Landlord to Tenant. If Landlord transfers its
interest in the Premises during the term of the Lease, Landlord may assign the
Security Deposit to the transferee and thereafter shall have no further
liability for the return of such Security Deposit.

     36. Notice. Any notice in the Lease provided for must, unless otherwise
expressly provided herein, be in writing, and may, unless otherwise in this
Lease expressly provided, be given or be served by depositing the same in the
United States mail, postpaid and certified and addressed to the party to be
notified, with return receipt requested. Notice deposited in the mail in the
manner hereinabove described shall be effective from and after the expiration
of three (3) days after it is so deposited. Notices mailed shall be addressed
to the parties at the following addresses:

or in each case to such other address as either party may from time to time
designate in writing.

    37. Severability. If any term or provision of this Lease, or the
application thereof to any person or circumstance shall, to any extent, be
invalid or unenforceable, the remainder of this Lease, or the application of
such term or provision to persons or circumstances other than those as to which
it is held invalid or unenforceable, shall not be affected thereby, and each
term and provision of this Lease shall be valid and enforced to the fullest
extent permitted by law.

    38. Recordation. Tenant agrees not to record this Lease.

    39. Governing Law. This Lease and the rights and obligations of the parties
hereto shall be interpreted, construed, and enforced in accordance with the
laws of the State of Oklahoma.

    40. Force Majeure. Whenever a period of time is herein prescribed for the
taking of any action by Landlord, Landlord shall not be liable or responsible
for, and there shall be excluded from the computation of such period of time,
any delays due to strikes, riots, acts of God, shortages of labor or materials,
war, governmental laws, regulations or restrictions, or any other cause
whatsoever beyond the control of Landlord.

     41. Time of Performance. Except as expressly otherwise herein provided,
with respect to all required acts of Tenant time is of the essence of this
Lease.

    42. Transfers by Landlord. Landlord shall have the right to transfer and
assign, in whole or in part, a11 its rights and obligations hereunder and in
the Premises, the Building, the Project, and property referred to herein, and
in such event and upon such transfer Landlord shall be released from any
further obligations hereunder and Tenant agrees to look solely to Landlord's
successor in interest then occupying Landlord's position hereunder for the
performance of such obligations.

    43. Effect of Delivery of This Lease. Landlord has delivered a copy of this
Lease to Tenant for Tenant's review only, and the delivery hereof does not
constitute an offer or option to Tenant for Tenant to lease the Premises. This
Lease shall not be effective until a copy executed by both Landlord and Tenant
is delivered to and accepted by Landlord.

    44. Relocation. In the event the Premises contain 2,500 square feet or less
of Net Rentable Area of the Premises, Landlord shall be entitled to cause
Tenant to relocate from the Premises to a comparable space ("Relocation Space")
within the Building at any time after reasonable written notice not in excess
of ninety (90) days is given to Tenant of Landlord's election. Any such
relocations shall be entirely at the expense of Landlord or the third party
tenant replacing Tenant in the Premises. Such a relocation shall not terminate
or otherwise affect or modify this Lease except that from and after the date of
such relocation, "Premises" shall refer to the Relocation Space into which
Tenant

                                       14
<PAGE>   14

has been moved, rather than the original Premises as herein defined.

    45. Building Name. Landlord reserves the right at any time and from time to
time to change the name by which the Building is designated.

                 2.01  Lease Of Premises.  Landlord leases to Tenant and Tenant
leases from Landlord the premises ("Premises") shown on Exhibit A which are or
will be contained in the office building ("Building") located at the address
stated in 1.01A, which Building is part of an office building complex known as
the name given in 1.01A, upon the following terms and conditions.  For purposes
of this Lease,  "Complex" shall mean all land, building and other improvements
including the "Common Areas" (hereinafter defined) associated with the Building
located on the real property described in Exhibit A-1.  It is agreed that the
rentable area of the Premises is as shown on Exhibit A and contains the number
of square feet of area stated in 1.01J (the "Rentable Area").

                 2.02  Term.  The term of this Lease ("Term") shall commence on
the date ("Commencement Date") which is the earlier to occur of (i) the date
stated in 1.01G or (ii) the date Tenant first occupies all or part of the
Premises for the conduct of business.  The Term shall expire on the date
("Expiration Date") stated in 1.01H unless sooner terminated as otherwise
provided in this Lease.  The Commencement Date and the Expiration Date may be
extended in accordance with the work letter attached as Exhibit C ("Work
Letter").  Landlord and Tenant agree to execute and deliver a written
declaration, in recordable form, expressing the actual Commencement Date and
Expiration Date.


                                    3.  RENT

                 Tenant agrees to pay to Landlord at the office of the
Landlord's building manager ("Manager"), or at such other place designated by
Landlord, without any prior notice or demand and without any deduction
whatsoever, base rent at the initial monthly rate stated in 1.01I on a per diem
basis ("Monthly Base Rent").  Monthly Base Rent shall be paid monthly in
advance on or before the first day of each month of the Term, except that the
first installment of Monthly Base Rent shall be paid by Tenant to Landlord on
the Commencement Date.  Tenant shall further pay Tenant's share of Operating
Costs as provided in 22.02.  Monthly Base Rent shall be prorated on a per diem
basis for partial months within the Term.  All charges, costs and sums required
to be paid by Tenant to Landlord under this Lease and under the Work Letter, in
addition to Monthly Base Rent shall be considered additional rent, and shall be
collectively called "Rent."  Tenant's covenant to pay Rent shall be independent
of every other covenant in this Lease.


                              4.  SECURITY DEPOSIT


                            [Intentionally Deleted]


                                  5. SERVICES

                 5.01  Landlord's General Services.  Landlord shall provide the
following services:  (1) heat and air-conditioning in the Premises, Monday
through Friday from 8:00 a.m. to 6:00 p.m. and Saturday from 8:00 a.m. to 1:00
p.m., excluding national holidays, to the extent necessary for the comfortable
occupancy of the Premises under normal business operations (subject, however,
to applicable legal requirements and restrictions) and in the absence of the
use of machines, equipment or devices which





                                       3
<PAGE>   6
affect the temperature otherwise maintained in the Premises; (2) city water
from the regular Building fixtures for drinking, lavatory and toilet purposes
only; (3) customary cleaning and janitorial services in the Premises Monday
through Friday, excluding national holidays; (4) customary cleaning, mowing,
grounds keeping, snow removal and trash removal in the "Common Areas"
(hereinafter defined); (5) washing of windows in the Premises, inside and

common with other tenants of the Building; and (7) freight elevator service
during operating hours subject to scheduling by Landlord.  Additional capacity
or usage shall be provided at the option of Landlord (reasonably exercised) and
at the sole cost of Tenant.

                 5.02  Additional And After-Hour Services.  Landlord shall not
be obligated to furnish any services or utilities, other than those stated in
5.01 above.  If Landlord elects to furnish services or utilities requested by
Tenant in addition to those listed in 5.01 or at times other than those stated
in 5.01, Tenant shall pay to Landlord as additional Rent, the prevailing
charges for such services and utilities, within ten (10) days after billing.
If Tenant fails to make any such payment, Landlord may, without notice to
Tenant and in addition to Landlord's other remedies under this Lease,
discontinue any or all of such additional or after-hour services.  No such
discontinuance of any service shall result in any liability of Landlord to
Tenant or be considered an eviction or a disturbance of Tenant's use of the
Premises.

                 5.03  Delays in Furnishing Services.  If as a result of any
failure to furnish or delay in furnishing any of the services described in
5.01, the Premises are rendered substantially untenantable for a period of more
than seventy-two (72) consecutive hours and Tenant does not occupy the Premises
due to such untenantability, then, commencing upon the expiration of said
72-hour period, Monthly Base Rent shall abate for the duration of such
untenantability until Tenant is able to resume or does resume occupancy of the
Premises.  Tenant agrees that Landlord shall not be liable for damages for
failure to furnish or delay in furnishing any service if attributable to any of
the causes described in 26.05 and if not thus attributable, then only to the
extent of abatement of Monthly Base Rent.  No failure or delay shall be
considered to be an eviction or disturbance of Tenant's use or possession of
Premises.

                 5.04  Telephone.  Tenant shall make arrangements directly with
a telephone company for telephone service in the Premises desired by Tenant.
Tenant shall pay for all telephone service used or consumed in the Premises,
including the cost of installation, maintenance and replacement of any items.

                 5.05  Electricity.  Landlord shall provide electrical conduit
and wiring to the boundary of the Premises with sufficient capacity to provide
electricity for normal business usage for lights and business machines.
Tenant's usage of electricity shall be separately metered and Tenant shall pay
for all electricity used in the Premises and for the installation and
maintenance of the meter.  Such costs shall not be included in Operating Costs
as defined in 22.01C.


                       6.  POSSESSION, USE AND ENJOYMENT

                 6.01  Possession and Use of Premises.  Tenant shall be
entitled to possession of the Premises when the Work is "substantially
completed" (as defined in the Work Letter).





                                       4
<PAGE>   7
Tenant shall occupy and use the Premises for general office purposes only.
Tenant shall be entitled to access to the Premises twenty-four (24) hours a day
seven (7) days a week, subject to reasonable security policies and restrictions
of Landlord.  Tenant shall not occupy or use the Premises or permit the use or
occupancy of the Premises for any purpose or in any manner which:  (1) is
unlawful or in violation of any applicable legal, governmental or
quasi-governmental requirement, ordinance or rule (including the Board of Fire
Underwriters); (2) may be dangerous to persons or property; (3) may invalidate
or increase the amount of premiums for any policy of insurance affecting the
Building or the Complex, and if any additional amounts of insurance premiums
are so incurred, Tenant shall pay to Landlord the additional amounts on demand
and such payment shall not authorize such use; (4) may create a nuisance,
disturb any other tenant of the Building or the Complex or the occupants of
neighboring property or injure the reputation of the Building or the Complex;
or (5) violates the Rules and Regulations of the Building or any restrictions
of record as they are now or may be modified.  A copy of the Rules and
Regulations is attached to this Lease as Exhibit B.

                 6.02  Quiet Enjoyment.  So long as Tenant is not in default
under this Lease, Tenant shall be entitled to peaceful and quiet enjoyment of
the Premises, subject to the terms of this Lease.

                 6.03  Common Areas.

                          A.  For purposes of this Lease "Common Areas" shall
         mean all areas, improvements, space, equipment and special services in
         or serving the Complex provided by Landlord for the common or joint
         use and benefit of tenants, customers, and other invitees, including
         without limitation garage access roads, driveways, entrances and
         exits, skywalks connected to the Building, retaining walls, landscaped
         areas, truck serviceways or tunnels, loading docks, pedestrian
         walk-ways, atriums, walls, courtyards, concourses, stairs, ramps,
         sidewalks, washrooms, signs identifying or advertising the Complex,
         maintenance buildings, utility buildings, maintenance and utility
         rooms and closets, hallways, lobbies, elevators and their housing and
         rooms, common window areas, walls and ceilings in Common Areas, and
         trash or rubbish areas.

                          B.  Provided Tenant is not in default under this
         Lease, Tenant shall be entitled to use, in common with others entitled
         thereto, the Common Areas (other than any portion of the riverwalk
         areas that might be part of the Complex) as may be designated from
         time to time by Landlord, subject however to the terms and conditions
         of this Lease and to the rules and regulations for the use thereof as
         may be prescribed from time to time by Landlord.  If the size or
         configuration of the Common Areas is diminished or altered, Landlord
         shall not be liable to Tenant therefor, nor shall Tenant be entitled
         to any compensation or diminution or abatement of Rent, nor shall such
         diminution or alteration of the Common Areas be considered a
         constructive or actual eviction.


                           7.  CONDITION OF PREMISES

                 Tenant shall notify Landlord in writing within thirty (30)
days after Tenant takes possession of the Premises of any defects in the
Premises claimed by Tenant.  Except for defects





                                       5
<PAGE>   8
stated in such notice and latent defects discovered within one (1) year after
such possession, Tenant shall be conclusively presumed to have accepted the
Premises in the condition existing on the date Tenant first takes possession,
and to have waived all claims relating to the condition of the Premises.  No
agreement of Landlord to alter, remodel, decorate, clean or improve the
Premises, the Building, the Common Areas or the Complex and no representation
regarding the condition of the Premises, the Building, the Common Areas or the
Complex has been made by or on behalf of Landlord to Tenant, except as stated
in this Lease or in the Work Letter.  Landlord shall use reasonable efforts to
correct any defect in the Premises reported by Tenant within thirty (30) days
after Landlord receives such notice from Tenant.


                         8.  ASSIGNMENT AND SUBLETTING

                 8.01  Assignment and Subletting.  Without the prior written
consent of Landlord, Tenant shall not sublease the Premises, or assign,
mortgage, pledge, hypothecate or otherwise transfer or permit the transfer of
this Lease or the interest of Tenant in this Lease, in whole or in part, by
operation of law, court decree or otherwise.  Landlord's consent shall not be
unreasonably withheld or delayed.  Landlord will not be deemed to have
unreasonably withheld its consent if it does so because (a) the subtenant's or
assignee's use of the Premises is in contravention of 6.01 hereof, or breaches
any exclusive rights granted any other tenant; (b) the proposed subtenant or
assignee has defaulted under any other leases with Landlord for space in the
building or elsewhere; (c) the subtenant's or assignee's intended use of the
Premises is reasonably expected to either (i) increase the Landlord's common
area maintenance or operating costs over those attributable to Tenant's use of
the Premises; or (ii) be incompatible with the other tenant mix in the
building; or (d) the subtenant or assignee is not credit worthy or, in
Landlord's reasonable judgement, financially capable of performing Tenant's
obligations under this Lease.  The enumeration of the foregoing reasons shall
not be deemed to exclude other reasons for denying consent.  If Tenant desires
to assign this Lease or enter into any sublease of the Premises, Tenant shall
deliver written notice of such intent to Landlord, together with a copy of the
proposed assignment or sublease at least sixty (60) days prior to the effective
date of the proposed assignment or commencement date of the term of the
proposed sublease.  Landlord shall respond to the proposed assignment or
sublease at least thirty (30) days prior to the effective date of the proposed
assignment or commencement date of the term of the proposed sublease.  Any
sublease shall be expressly subject to the terms and conditions of this Lease,
and Tenant shall pay Landlord on the first day of each month during the term of
the sublease, fifty percent (50%) of the excess of all rent and other
consideration due from the subtenant for such month over that portion of the
Monthly Base Rent due under this Lease for said month which is allocable on a
square footage basis to the space sublet.  In the event of any sublease or
assignment, Tenant shall not be released or discharged from any liability,
whether past, present or future, under this Lease, including any renewal term
of this Lease.  For purposes of this Section, an assignment shall be considered
to include a change in the majority ownership or control of Tenant if Tenant is
a partnership or a corporation whose shares of stock are not traded publicly;
provided, however, in the event the net worth of the Tenant after such change
in majority ownership or control is equal to or greater than the net worth of
the Tenant prior thereto (in the reasonable opinion of Landlord), Landlord's
consent to such change in the majority ownership or control of Tenant shall not
be required.  Tenant





                                       6
<PAGE>   9
shall reimburse Landlord for all reasonable costs incurred by Landlord in
connection with the proposed assignment or sublease, including without
limitation attorneys' fees, brokerage fees and costs incurred in connection
with review and investigation of the proposed assignee or subtenant.

                 Anything contained in the foregoing provisions of this Section
to the contrary notwithstanding, neither Tenant nor any other person having an
interest in the possession, use, occupancy or utilization of the Premises shall
enter into any lease, sublease, license, concession or other agreement for use,
occupancy or utilization of space in 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 premises
leased, used, occupied or utilized (other than an amount based on a fixed
percentage or percentages of receipts or sales), and 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.

                 8.02  Recapture.  If Tenant desires to enter into any sublease
of the Premises, Landlord shall have the option to exclude from the Premises
covered by this Lease, the space proposed to be sublet by Tenant, effective as
of the proposed commencement date of sublease of said space by Tenant.
Landlord may exercise said option by giving Tenant written notice within twenty
(20) days after receipt by Landlord of Tenant's notice of the proposed
sublease; provided, however, in the event Landlord exercises its right to
exclude any such portion or all of the Premises from this Lease, Tenant shall
have the right, by written notice delivered to Landlord within five (5) days
after receipt by Tenant of Landlord's exercise notice, to rescind Tenant's
request to sublease such portion or all of the Premises, and Tenant's request
to sublease all or a portion of the Premises and Landlord's exercise of the
option contained in this Section 8.02 shall be deemed null and void.  If
Landlord exercises said option, Tenant shall surrender possession of the
proposed sublease space to Landlord on the effective date of exclusion of said
space from the Premises covered by this Lease, and neither party hereto shall
have any further rights or liabilities with respect to said space under this
Lease.  Effective as of the date of exclusion of any portion of the Premises
covered by this Lease pursuant to this paragraph, (i) the Monthly Base Rent
shall be reduced in the same proportion as the number of square feet of
Rentable Area contained in the portion of the Premises so excluded bears to the
number of square feet of Rentable Area contained in the Premises immediately
prior to such exclusion, and (ii) the Rentable Area of the Premises specified
in 1.01J shall be decreased by the number of square feet of Rentable Area
contained in the portion of the Premises so excluded, for all purposes under
this Lease.


                                9.  MAINTENANCE

                 9.01  Landlord's Maintenance.  Landlord, at its expense, shall
maintain and make necessary repairs to the structural elements and exterior
windows of the Building and the Common Areas, and, subject to 15.04, the
electrical, plumbing, heating, ventilation and air conditioning systems of the
Building and the Common Areas, except that:

                       A.  Landlord shall not be responsible for the
        maintenance, repair or replacement of any such systems which





                                       7
<PAGE>   10
         are located within the Premises and are supplemental or special to the
         Building's standard systems, whether installed pursuant to the Work
         Letter or otherwise, or floor or wall coverings in the Premises; and

                          B.  The cost of performing any of said maintenance or
         repairs caused by the negligence of Tenant, its employees, agents,
         servants, licensees, subtenants, contractors or invitees, or the
         failure of Tenant to perform its obligations under this Lease shall be
         paid by Tenant, except to the extent of insurance proceeds, if any,
         actually collected by Landlord with regard to the damage necessitating
         such repairs.  Tenant shall perform such repairs subject to the
         procedures established in 10.01 herein.

                 9.02  Tenant's Maintenance.  Tenant, at its expense, shall
keep and maintain the Premises in good order, condition and repair and in
accordance with all applicable legal, governmental and quasi-governmental
requirements, ordinances and rules (including the Board of Fire Underwriters).

                 9.03  Maintenance of Common Areas.  The Common Areas shall be
subject to the control, management, operation and maintenance of Landlord.
Landlord shall have the right from time to time to establish, modify and
enforce rules and regulations with respect to the Common Areas.  Tenant agrees
to comply with such rules and regulations, to cause its officers, agents,
contractors and employees to so comply and to use its best efforts to cause its
customers, invitees, concessionaires, suppliers and licensees to so comply.
Landlord shall have the right to construct, maintain and operate lighting and
other facilities in and on the Common Areas; to grant third parties temporary
rights of use thereof; from time to time to change the area, level, location or
arrangement of parking areas and other facilities located in the Common Areas
(provided such change does not unreasonably affect Tenant's parking rights
provided herein); to close all or any portion of the Common Areas to such
extent as may, in the opinion of Landlord, be legally sufficient to prevent a
dedication thereof or accrual of any rights to any person or the public
therein; to close temporarily all or any part of the parking areas or parking
facilities; and to do and perform such other acts in and to the Common Areas
as, in the exercise of good business judgment, Landlord shall determine to be
advisable.  Landlord will operate and maintain the Common Areas in such manner
as Landlord, in its sole discretion, shall determine from time to time.  In
exercising its rights under this 9.03, Landlord shall use reasonable efforts to
minimize any interference with Tenant's use of the Premises and Common Areas.


               10.  ALTERATIONS AND IMPROVEMENTS SUBSEQUENT TO INITIAL OCCUPANCY

                 10.01  Tenant's Alterations Subsequent to Initial Occupancy.
Tenant shall not, without the prior written consent of Landlord, make or cause
to be made any alterations, improvements, additions or installations in or to
the Premises subsequent to the initial occupancy of the Premises by Tenant.  If
Landlord so consents, before commencement of any such work or delivery of any
materials into the Premises or the Building, Tenant shall furnish to Landlord
for approval:  architectural plans and specifications, names and addresses of
all contractors, contracts, necessary permits and licenses, certificates of
insurance 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 and amount as may





                                       8
<PAGE>   11
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 evidence reasonably satisfactory to Landlord of Tenant's ability
to pay for such work and materials in full, and, if requested by Landlord,
shall deposit with Landlord at such time such security for the payment of said
work and materials as Landlord may require.  Tenant agrees to hold Landlord,
the Manager and their respective agents and employees forever harmless against
all claims and liabilities of every kind, nature and description which may
arise out of or in any way be connected with such work.  All such work shall be
done only by contractors or mechanics approved in writing by Landlord and at
such time and in such manner as Landlord may from time to time designate.
Tenant shall pay the cost of all such work.  Upon completion of such work,
Tenant shall furnish Landlord with contractors' affidavits and full and final
waivers of lien and receipted bills covering all labor and materials expended.
All such work shall be in compliance with all applicable legal, governmental
and quasi-governmental requirements, ordinances and rules (including the Board
of Fire Underwriters), and all requirements of applicable insurance companies.
All such work shall be done in a good and workmanlike manner and with the use
of good grades of materials including fire protection grades equivalent with
those of the Building.  Tenant shall permit Landlord, if Landlord so desires,
to supervise construction operations in connection with such work; provided,
however, that such supervision or right to supervise by Landlord and the
approval or disapproval of the plans and specifications for such work in any
situation shall not constitute any warranty by Landlord to Tenant of the
adequacy of the design, workmanship or quality of such work or materials for
Tenant's intended use or impose any liability upon Landlord in connection with
the performance of such work.  All alterations, improvements, additions and
installations to or on the Premises shall (subject to Article 13) become part
of the Premises at the time of their installation and shall remain in the
Premises at the expiration or termination of this Lease or termination of
Tenant's right to possession of the Premises, without compensation or credit to
Tenant; provided, however, all such alterations, improvements, additions and
installations shall remain the personal property of the Tenant for tax purposes
during the Term of this Lease.

                 10.02  Decorative Alterations.  Notwithstanding the foregoing,
nothing herein shall be deemed to require the Landlord's consent for decorative
alterations such as installation of wall coverings, hanging of paintings,
prints and other wall hangings, painting of walls or similar alterations
affecting only the interior of the Premises.

                 10.03  Liens.  Tenant shall not permit any lien or claim for
lien of any mechanic, laborer or supplier or any other lien to be filed against
the Complex, the Building, the Common Areas, the land which comprises the
Complex, the Premises, or any part of such property arising out of work
performed, or alleged to have been performed by, or at the direction of, or on
behalf of Tenant.  If any such lien or claim for lien is filed, Tenant shall
within five (5) days after such filing either have such lien or claim for lien
released of record or shall deliver to Landlord a bond or other security in
form, content, amount, and issued by a company satisfactory to Landlord
indemnifying Landlord, Manager and others designated by Landlord against all
costs and liabilities resulting from such lien or claim for lien and the
foreclosure or attempted foreclosure thereof.  If Tenant fails to have such
lien or claim for lien so released or to deliver such bond to Landlord,
Landlord, without investigating





                                       9
<PAGE>   12
the validity of such lien, may pay or discharge the same and Tenant shall
reimburse Landlord upon demand for the amount so paid by Landlord, including
Landlord's expenses and attorneys' fees.


                      11.  WAIVER OF CLAIMS AND INDEMNITY

                 11.01  Waiver.  To the fullest extent permitted by law, Tenant
hereby releases and waives all claims against Landlord, the Manager and their
respective agents and employees for injury or damage to person or property
sustained in or about the Complex, the Building or the Premises by Tenant, its
agents or employees other than damage caused by the negligence of Landlord, the
Manager or their respective agents or employees.

                 11.02  Indemnification.

                          A.      Tenant agrees to indemnify, defend and hold
         harmless Landlord, the Manager and their respective agents and
         employees, from and against any and all liabilities, claims, demands,
         costs and expenses of every kind and nature (including attorneys'
         fees), including those arising from any injury or damage to any person
         (including death) or property (a) sustained in or about the Premises,
         (b) resulting from the negligence or willful act of Tenant, its
         employees, agents, servants, invitees, licensees or subtenants, or (c)
         resulting from the failure of Tenant to perform its obligations under
         this Lease; provided, however, Tenant's obligations under this section
         shall not apply to injury or damage resulting from the negligence or
         willful act of Landlord, the Manager or their respective agents or
         employees.

                          B.      Landlord agrees to indemnify, defend and hold
         harmless Tenant, and its respective agents and employees, from and
         against any and all liabilities, claims, demands, costs and expenses
         of every kind and nature (including attorneys' fees), arising from any
         injury or damage to any person (including death) or property (a)
         sustained in or about the Building and resulting from the negligence
         or willful act of Landlord, its employees, agents or servants, or (b)
         resulting from the failure of Landlord to perform its obligations
         under this Lease; provided, however, Landlord's obligations under this
         Section shall not apply to injury or damage resulting from the
         negligence or willful act of Tenant, or its respective agents or
         employees.

                 11.03  Waiver of Subrogation.  Notwithstanding such waiver and
indemnification or anything else to the contrary contained in this Lease:

                          A.  Tenant shall not be responsible or liable to
         Landlord for any loss resulting from a peril to the extent that
         Landlord is required to insure against such peril hereunder.  Landlord
         shall cause its policy or policies of insurance to contain effective
         waivers of subrogation for the benefit of Tenant.

                          B.  Landlord and Manager shall not be responsible or
         liable to Tenant for any event, act or omission to the extent covered
         by insurance required to be obtained and maintained by Tenant with
         respect to the Premises and its use and occupancy thereof (whether or
         not such insurance is actually obtained or maintained) and the
         proceeds of such other insurance as is obtained and maintained by
         Tenant with





                                       10
<PAGE>   13
         respect to the Premises and to its use and occupancy thereof.  Tenant
         shall cause its policy or policies of insurance to contain effective
         waivers of subrogation for the benefit of Landlord.


                             12.  EVENTS OF DEFAULT

                 12.01  Events of Default.  Each of the following shall
constitute an event of default by Tenant under this Lease:  (1) Tenant fails to
pay any installment of Rent when due, and such failure continues for five (5)
days after written notice to Tenant (provided Landlord shall not be obligated
to give more than two (2) such notices in any calendar year, and any failure by
Tenant to pay rent when due in any calendar year after Landlord has given
Tenant such notices shall immediately be considered an event of default); (2)
Tenant fails to observe or perform any of the other non-monetary covenants,
conditions or provisions of this Lease or under the Work Letter to be observed
or performed by Tenant and fails to cure such non-monetary default within
fifteen (15) days after written notice to Tenant, provided, however, in the
event Tenant is unable in good faith to cure any non-monetary default within
such fifteen (15) days, and further provided Tenant proceeds prudently and
diligently to cure such default, Tenant shall have a reasonable time thereafter
to cure such default; (3) the interest of Tenant in this Lease is levied upon
through execution or other legal process; (4) a petition is filed by Tenant to
declare Tenant bankrupt or seeking a plan of reorganization or arrangement
under any Chapter of the Bankruptcy Code, or any amendment, replacement or
substitution therefor, or to delay payment of, reduce or modify Tenant's debts,
or an involuntary petition is filed by or against Tenant to declare Tenant
bankrupt or seeking a plan of reorganization or arrangement under any Chapter
of the Bankruptcy Code, or any amendment, replacement or substitution therefor,
or to delay payment of, reduce or modify Tenant's debts, and such involuntary
petition is not dismissed within sixty (60) days after the same is filed, or
any petition is filed or other action taken to reorganize or modify Tenant's
capital structure or upon the dissolution of Tenant; (5) Tenant is declared
insolvent by law or any assignment of Tenant's property is made for the benefit
of creditors; (6) a receiver is appointed for Tenant or Tenant's property; (7)
Tenant abandons the Premises; or (8) Tenant fails to provide or maintain the
Tenant's Lease Collateral as provided in Rider No. 2 hereof.


                 12.02  Late Charges.  All delinquent Rent shall bear interest
at the maximum rate permitted by law or fifteen percent (15%) per annum,
whichever is less, from the date due (prior to any grace period for payment)
until paid.

                 12.03  Landlord's Remedies.  Upon the occurrence of an event
of default by Tenant under this Lease, Landlord, at its option, without further
notice or demand to Tenant, may in addition to all other rights and remedies
provided in this Lease, at law or in equity:

                          A.  Terminate this Lease and Tenant's right of
         possession of the Premises, and recover all damages to which Landlord
         is entitled under law, specifically including, without limitation: (a)
         the sum of all rental and other payments owed to Landlord hereunder
         accrued to the date of such termination; (b) all Landlord's expenses
         of reletting (including repairs, alterations, improvements, additions,
         decorations, legal fees and brokerage commissions) to the





                                       11
<PAGE>   14
         extent provided for in Chapter 704, Wis. Stats.; and (c) as liquidated
         damages, an amount equal to (i) the present value of the total rental
         and other payments owed hereunder for the remaining portion of the
         Lease Term, calculated as if such term expired on the date set forth
         in 1.01(H), less (ii) the then present fair market rental value of the
         Premises for such period.

                          B.  Terminate Tenant's right of possession of the
         Premises without terminating this Lease, in which event Landlord shall
         be entitled to all remedies available under Wisconsin law and equity,
         including without limitation, Section 704.29, Wis. Stats., provided
         Landlord shall use reasonable efforts to relet the Premises, or any
         part thereof for the account of Tenant, for such rent and term and
         upon such terms and conditions as are then reasonably obtainable.  For
         purposes of such reletting Landlord is authorized to redecorate,
         repair, alter and improve the Premises to the extent provided for by
         Chapter 704, Wis. Stats.  Until Landlord does relet the Premises,
         Tenant shall pay Landlord monthly on the first day of each month
         during the period that Tenant's right of possession is terminated, a
         sum equal to the amount of Rent due under this Lease for such month.
         If and when the Premises are relet and a sufficient sum is not
         realized from such reletting after payment of all Landlord's expenses
         of reletting permitted under Chapter 704, Wis. Stats.  (including
         repairs, alterations, improvements, additions, decorations, legal fees
         and brokerage commissions) to satisfy the payment of Rent due under
         this Lease for any month, Tenant shall pay Landlord any such
         deficiency monthly upon demand.  Tenant agrees that Landlord may file
         suit to recover any sums due to Landlord under this Section from time
         to time and that such suit or recovery of any amount due Landlord
         shall not be any defense to any subsequent action brought for any
         amount not previously reduced to judgment in favor of Landlord.  If
         Landlord elects to terminate Tenant's right to possession only without
         terminating this Lease, Landlord may, at its option, enter into the
         Premises, remove Tenant's signs and other evidences of tenancy, and
         take and hold possession thereof, as stated in Article 13; provided,
         however, that such entry and possession shall not terminate this Lease
         or release Tenant, in whole or in part, from Tenant's obligation to
         pay the Rent reserved hereunder for the full Term or from any other
         obligation of Tenant under this Lease.  Nothing contained herein shall
         be deemed to affect Landlord's obligation to mitigate damages.

                          C.  Upon the filing of a petition by or against the
         Tenant under the Bankruptcy Code, the Tenant, as debtor and as
         debtor-in-possession, and any trustee who may be appointed agree as
         follows:  (a) to perform each and every obligation of Tenant under
         this Lease until such time as this Lease is either rejected or assumed
         by order of the United States Bankruptcy Court; (b) to pay monthly in
         advance on the first day of each month as reasonable compensation for
         use and occupancy of the Premises an amount equal to all Rent and
         other charges otherwise due pursuant to this Lease; (c) to reject or
         assume this Lease within sixty (60) days of the filing of such
         petition; (d) to give Landlord at least forty-five (45) days prior
         written notice of any proceeding relating to any assumption of this
         Lease; (e) to give at least thirty (30) days prior written notice of
         any abandonment of the Premises; any such abandonment to be deemed a
         rejection of this Lease; (f) to do all other things of benefit to the
         Landlord otherwise required under





                                       12
<PAGE>   15
         the Bankruptcy Code; (g) to be deemed to have rejected this Lease in
         the event of the failure to comply with any of the above; and (h) to
         have consented to the entry of an order by an appropriate United
         States Bankruptcy Court providing all of the above, waiving notice and
         hearing of the entry of same.  No default of this Lease by the Tenant,
         either prior to or subsequent to the filing of such a petition, shall
         be deemed to have been waived unless expressly done so in writing by
         the Landlord.

                 12.04  Attorneys' Fees.  Tenant shall pay, upon demand, all
costs and expenses, including reasonable attorneys' fees, incurred by Landlord
in enforcing Tenant's obligations under this Lease or in the Work Letter or
resulting from Tenant's default under this Lease.  Landlord shall pay, upon
demand, all costs and expenses, including reasonable attorneys' fees, incurred
by Tenant in enforcing Landlord's obligations under this Lease and the Work
Letter or resulting from Landlord's default under this Lease.


                           13.  SURRENDER OF PREMISES

                 Upon the expiration or termination of this Lease or
termination of Tenant's right of possession of the Premises, Tenant shall
surrender and vacate the Premises immediately and deliver possession thereof to
Landlord in a clean, good and tenantable condition, ordinary wear excepted.
Upon any termination which occurs other than by reason of Tenant's default,
Tenant shall be entitled to remove from the Premises all unattached and
moveable trade fixtures and personal property of Tenant without credit or
compensation from Landlord, provided Tenant immediately shall repair all damage
resulting from such removal and shall restore the Premises to a tenantable
condition.  In the event possession of the Premises is not immediately
delivered to Landlord or if Tenant shall fail to remove any unattached and
movable trade fixtures or personal property which Tenant is entitled to remove,
Landlord may remove same without any liability to Tenant.  Any movable trade
fixtures and personal property which may be removed from the Premises by Tenant
but which are not so removed upon the vacancy of the Premises shall be
conclusively presumed to have been abandoned by Tenant and title to such
property shall pass to Landlord without any payment or credit and Landlord may,
at its option and at Tenant's expense, store and/or dispose of such property.


                               14.  HOLDING OVER

                 Tenant shall pay Landlord double the Rent then applicable for
each month or partial month during which Tenant retains possession of the
Premises, or any part of the Premises, after the expiration or termination of
this Lease, or the termination of Tenant's right of possession of the Premises.
Tenant shall also indemnify Landlord against all liabilities and damages
sustained by Landlord by reason of such retention of possession.  The
provisions of this Article shall not constitute a waiver by Landlord of any
re-entry rights of Landlord available under this Lease or by law.


                     15.  DAMAGE BY FIRE OR OTHER CASUALTY

                 15.01  Substantial Untenantability.  If either the Premises,
the Building or the Complex is rendered substantially untenantable by fire or
other casualty, Landlord may elect by





                                       13
<PAGE>   16
giving Tenant written notice within one hundred twenty (120) days after the
date of said fire or casualty, either to: (1) terminate this Lease as of the
date of the fire or other casualty; or (2) proceed to repair or restore the
Premises, the Building or the Complex (other than leasehold improvements and
personal property installed by Tenant), to substantially the same condition as
existed immediately prior to such fire or casualty.

                 If Landlord elects to proceed pursuant to subsection (2)
above, Landlord's notice shall contain Landlord's reasonable estimate of the
time required to substantially complete such repair or restoration.  If such
estimate indicates that the time so required will exceed one hundred eighty
(180) days from the date of the casualty, then Tenant shall have the right to
terminate this Lease as of the date of such casualty by giving written notice
to Landlord not later than twenty (20) days after the date of the Landlord's
notice.  If Landlord's estimate indicates that the repair or restoration can be
substantially completed within one hundred eighty (180) days, or if Tenant
fails to exercise its said right to terminate this Lease, this Lease shall
remain in force and effect.

                 15.02  Insubstantial Untenantability.  If either the Premises,
the Building or the Complex is damaged by fire or other casualty but is not
rendered substantially untenantable, then Landlord shall diligently proceed to
repair and restore the damaged portions thereof, other than the leasehold
improvements and all personal property installed by Tenant, to substantially
the same condition as existed immediately prior to such fire or casualty,
unless such damage occurs during the last twelve (12) months of the Term, in
which event Landlord shall have the right to terminate this Lease as of the
date of such fire or other casualty by giving written notice to Tenant within
thirty (30) days after the date of such fire or other casualty.

                 15.03  Rent Abatement.  If all or any part of the Premises are
damaged by fire or other casualty and this Lease is not terminated, Monthly
Base Rent shall abate for all or that part of the Premises which are
untenantable on a per diem and proportionate area basis from three (3) days
after the date of the fire or other casualty until Landlord has substantially
completed the repair and restoration work in the Premises which it is required
to perform, provided, that as a result of such fire or other casualty, Tenant
does not occupy the portion of the Premises which are untenantable during such
period.

                 15.04  Tenant's Restoration.  If all or any part of the
Premises are damaged by fire or other casualty and this Lease is not
terminated, Tenant shall promptly and with due diligence repair and restore the
leasehold improvements, and all personal property previously installed by
Tenant pursuant to this Lease.


                              16.  EMINENT DOMAIN

                 16.01  Permanent Taking.  If all or any part of the Premises,
the Building or the Complex is permanently taken or condemned by any competent
authority for any public use or purpose (including a deed given in lieu of
condemnation), which renders the Premises substantially untenantable, this
Lease shall terminate as of the date title vests in such authority, and Monthly
Base Rent shall be apportioned as of such date.

                 16.02  Insubstantial Taking.  If any part of the Premises, the
Building or the Complex is taken or condemned for any public use or purpose
(including a deed given in lieu of





                                       14
<PAGE>   17
condemnation) and this Lease is not terminated pursuant to 16.01, Monthly Base
Rent shall be reduced for the period of such taking by an amount which bears
the same ratio to Monthly Base Rent then in effect as the number of square feet
of Rentable Area in the Premises so taken or condemned, if any, bears to the
number of square feet of Rentable Area specified in 1.01J.  Landlord, upon
receipt and to the extent of the award in condemnation or proceeds of sale,
shall make necessary repairs and restorations (exclusive of leasehold
improvements and personal property installed by Tenant) to restore the Premises
remaining to as near its former condition as circumstances will permit, and to
the Building and Complex to the extent necessary to constitute the portion of
same not so taken or condemned as a complete architectural unit.  In the event
of any taking or condemnation described in this 16.02, the Rentable Area of the
Premises stated in 1.01J and the Rentable Area of the Complex as specified in
this Lease, shall be reduced, respectively, for all purposes under this Lease
by the number of square feet of Rentable Area of the Premises, if any, and the
Complex, if any, so taken or condemned as determined and certified by an
independent professional architect selected by Landlord.

                 16.03  Compensation.  Landlord shall be entitled to receive
the entire price or award from any such sale, taking or condemnation without
any payment to Tenant, and Tenant hereby assigns to Landlord Tenant's interest,
if any, in such award; provided, however, Tenant shall have the right
separately to pursue against the condemning authority an award in respect of
the loss, if any, to leasehold improvements paid for by Tenant without any
credit or allowance from Landlord.  Under no circumstances shall the Tenant
seek or be entitled to any compensation for the value of its leasehold estate.


                                 17.  INSURANCE

                 17.01  Tenant's Insurance.  Tenant, at its expense, shall
maintain in force during the Term:

                          A.  Comprehensive general public liability insurance,
         which shall include coverage for personal liability, contractual
         liability, bodily injury (including death) and property damage, all on
         an occurrence basis with respect to the business carried on, in or
         from the Premises and Tenant's use and occupancy of the Premises with
         coverage for any one occurrence or claim of not less than $3,000,000
         or such other amount as Landlord may reasonably require upon not less
         than six (6) months prior written notice; and

                          B.  All risk coverage insurance for the replacement
         value of leasehold improvements (regardless of whether they belong to
         Landlord or Tenant) and Tenant's property (including fixtures,
         improvements and equipment) located in the Premises and such other
         insurance against such other perils and in such amounts as Landlord
         may from time to time reasonably require upon not less than ninety
         (90) days prior written notice, such requirement to be made on the
         basis that the required insurance is customary at the time for prudent
         tenants of properties similar to the Complex in the area of the city
         stated in 1.01A.

                 All insurance required to be maintained by Tenant shall be on
terms and with insurers reasonably acceptable to Landlord.  Landlord shall be
named as an additional insured and such insurance shall contain a cross
liability endorsement with respect to the comprehensive general public
liability insurance.





                                       15
<PAGE>   18
The policy will not change, lapse or be canceled, except after not less than
thirty (30) days prior written notice to Landlord of the intended change, lapse
or cancellation.  Tenant shall furnish to Landlord, if and whenever requested
by it, certificates or other evidences acceptable to Landlord as to the
insurance from time to time maintained by Tenant and the renewal or
continuation in force of such insurance.

                 17.02  Landlord's Insurance.  Landlord, at its expense, shall
maintain in force during the Term:

                          A.  Fire and extended coverage insurance for at least
         ninety percent (90%) of the replacement value of the Complex (other
         than those portions required to be insured by Tenant), less footings
         and foundations; and

                          B.  Comprehensive general public liability insurance
         with respect to the business carried on in the Complex with coverage
         for any one occurrence or claim of not less than $5,000,000.


                           18.  RULES AND REGULATIONS

                 Tenant agrees for itself and for its subtenants, employees,
agents, and invitees to comply with the Rules and Regulations attached hereto
as Exhibit B.  Landlord and Tenant agree that the Rules and Regulations may be
amended from time to time.  Said amendment shall become a part of this Lease
upon written notification to Tenant of the changes.  Landlord agrees that the
rules and regulations shall not be enforced in an inconsistent or
discriminatory manner.


                             19.  LANDLORD'S RIGHTS

                 Landlord shall have the following rights exercisable without
notice (except as expressly provided to the contrary) and without being deemed
an eviction or disturbance of Tenant's use or possession of the Premises or
giving rise to any claim for set-off or abatement of Rent: (1) to change the
name or street address of the Building or the Complex, upon thirty (30) days'
prior written notice to Tenant; (2) to install, affix and maintain all signs on
the exterior and/or interior of the Building and in and about the Complex; (3)

the Premises to prospective tenants at reasonable hours during the last nine
(9) months of the Term; (5) to change the arrangement of entrances, doors,
corridors, elevators and stairs in the Building including adding skywalks to
connect the Building to another building, provided that no such change shall
materially adversely affect access to the Premises; (6) to grant to any party
the exclusive right to conduct any business or render any service in or to the
Building, provided such exclusive right shall not operate to prohibit Tenant
from using the Premises for the purposes permitted hereunder; (7) to prohibit
the placing of vending or dispensing machines of any kind in or about the
Premises other than for the use by Tenant's employees; (8) to have access for
Landlord and other tenants of the Building to any mail chutes and boxes located
in or on the Premises according to the rules of the United States Post Office;
(9) to close the Building after normal business hours, except that Tenant and
its employees and invitees shall be entitled to admission at all times under
such regulations as Landlord





                                       16
<PAGE>   19
prescribes for security purposes; (10) to take any and all reasonable measures,
including inspections and repairs to the Premises or to the Building, as may be
necessary or desirable in the operation or protection thereof; (11) to retain
at all times master keys or pass keys to the Premises; (12) to install, operate
and maintain security systems which monitor, by closed circuit television or
otherwise, all persons entering and leaving the Building or the Complex; (13)
to install and maintain pipes, ducts, conduits, wires and structural elements
located in the Premises which serve other parts or other tenants of the
Building; and (14) to inspect the Premises from time to time to determine
compliance with Tenant's obligations under this Lease and to show the Premises
to prospective purchasers or lenders.  In exercising its rights under this
Section 19, Landlord shall use reasonable efforts to minimize any interference
with Tenant's use of the Premises and Common Areas.


                           20.  ESTOPPEL CERTIFICATE

                 Tenant shall from time to time, upon not less than ten (10)
days prior written request by Landlord or any mortgagee or ground lessor of the
Complex, deliver to Landlord or such mortgagee or ground lessor a statement in
writing certifying: (1) that this Lease and the Work Letter are unmodified and
in full force and effect or, if there have been modifications, that this Lease
and the Work Letter, as modified, are in full force and effect; (2) the amount
of Monthly Base Rent then payable under this Lease and the date to which Rent
has been paid; (3) that Landlord is not in default under this Lease or any work
letter agreement, or, if in default, a detailed description of such default(s);
(4) that Tenant is or is not in possession of the Premises, as the case may be;
and (5) such other information as may be requested.

                 If Tenant fails or refuses to execute, acknowledge and deliver
any such instrument within twenty (20) days after written demand, Landlord will
be entitled to execute, acknowledge and deliver any such instrument on behalf
of Tenant as Tenant's attorney-in-fact.  Tenant constitutes and irrevocably
appoints Landlord as Tenant's attorney-in-fact to execute, acknowledge and
deliver on behalf of Tenant any document described in this paragraph.


                           21.  RELOCATION OF TENANT

                 At any time after the date of this Lease, Landlord may
substitute for the Premises, other premises in the Complex (the "New
Premises"), in which event the New Premises shall be deemed to be the Premises
for all purposes under this Lease, provided: (1) the New Premises shall be
similar to the Premises in area and configuration; (2) the substitution shall
be made in order to lease the Premises to a tenant of the Complex who then
occupies, or as a result of such substitution will occupy, all or a substantial
part of the floor of the Building on which the Premises are located; (3) if
Tenant is then occupying the Premises, Landlord shall pay the actual and
reasonable expenses of physically moving Tenant, its property and equipment to
the New Premises and the actual and reasonable expense of replacing Tenant's
stationary rendered inaccurate due to such relocation; (4) Landlord shall give
Tenant not less than thirty (30) days prior written notice of such
substitution; and (5) Landlord, at its expense, shall improve the New Premises
with improvements substantially similar to those in the Premises at the time of
such substitution, if the Premises are then improved, or if not





                                       17
<PAGE>   20
then improved, Landlord, at its expense, shall improve the New Premises in
accordance with the Work Letter.


                     22.  ADJUSTMENTS TO MONTHLY BASE RENT

                 22.01  Definitions.  For the purpose of this Article 22, the
following words and phrases shall have the following meanings:

                          A.  "Adjustment Date" shall mean each January 1 
         occurring within the Term.

                          B.  "Adjustment Year" shall mean each calendar year 
         or partial calendar year during the Term of this Lease.

                          C.  "Operating Costs" shall mean all costs, expenses,
         Taxes and disbursements of every kind and nature which Landlord shall
         pay or become obligated to pay in connection with the management,
         operation, maintenance, replacement and/or repair of all buildings,
         improvements and land comprising the Complex and of the personal
         property, fixtures, machinery, equipment, systems and apparatus
         located in or used in connection therewith.  Operating Costs shall not
         include the following: (1) costs of improvement of the Premises and
         the premises of other tenants of the Building; (2) charges for
         depreciation of the building and improvements comprising the Complex;
         (3) interest and principal payments on mortgages; (4) ground rental
         payments; (5) real estate brokerage and leasing commissions; (6)
         salaries and other compensation of executive officers of the Manager
         senior to the individual Building or Complex manager; (7) any
         expenditures for which Landlord has been reimbursed (other than
         pursuant to proration of Operating Costs, rent adjustment and
         escalation provisions provided in leases); (8) capital improvements to
         the Complex, except with respect to the costs associated with capital
         improvements installed by Landlord for the purpose of reducing
         Operating Costs and then only the annual straight line amortization of
         such costs over the useful life thereof; and (9) replacements other
         than as a result of obsolescence.

                          D.  "Per Square Foot Operating Costs" shall mean the
         amount of Operating Costs for any Adjustment Year divided by the
         Rentable Square Footage of the Building as stated in 1.01M.

                          E.  "Taxes" shall mean all federal, state and local
         governmental taxes, assessments and charges (including transit or
         district taxes or assessments) of every kind or nature, whether
         general, special, ordinary or extraordinary, which Landlord shall pay
         because of or in connection with the ownership, improvements and land
         comprising the Complex, or of Landlord's personal property, fixtures,
         machinery, equipment systems and apparatus located therein or used in
         connection therewith (including any rental sales, leasing or similar
         taxes levied on or with respect to the Rent, or any part thereof,
         payable under the Lease in lieu of or in addition to general real
         and/or personal property taxes).  For purposes hereof, Taxes for any
         year shall be Taxes which are due for payment or paid in that year,
         rather than Taxes which are assessed or become a lien during such
         year.  There shall be included in Taxes for any year the amount of all
         fees, costs and expenses (including reasonable attorneys' fees) paid
         by Landlord during such year in seeking or





                                       18
<PAGE>   21
         obtaining any refund or reduction of Taxes and Tenant shall receive
         its pro rata share of the benefit of any such refund or reduction,
         even after the expiration or earlier termination of the Term.  Taxes
         in any year shall be reduced by the net amount of any tax refund
         received by Landlord during such year.  If a special assessment
         payable in installments is levied against the Complex, Taxes for any
         year shall include only the installment of such assessment and any
         interest paid during such year.  Taxes shall not include any federal,
         state or local sales, use, franchise, capital stock, inheritance,
         general income, gift or estate taxes, except that if a change occurs
         in the methods of taxation resulting in whole or in part in the
         substitution of any such taxes, or any other assessment, for any Taxes
         as above defined, such substituted taxes or assessments shall be
         included in the Taxes; provided, however, that Tenant shall be
         responsible for and shall pay personal property taxes on its
         personalty, even if such personalty includes improvements to the
         Building that may become the property of Landlord upon expiration or
         termination of this Lease.

                 22.02  Adjustments to Monthly Base Rent.  Throughout the Term,
Tenant shall pay with each payment of Monthly Base Rent, as additional Rent, a
portion of Operating Costs for the Complex.  Tenant's share of Operating Costs
shall be determined on the Commencement Date and on each Adjustment Date by
multiplying the Rentable Area of the Premises by the Per Square Foot Operating
Costs for the Adjustment Year in which such Commencement Date or Adjustment
Date occurs (based on Landlord's Projections pursuant to 22.03, and subject to
adjustment pursuant to 22.04).  Monthly installments of Tenant's share of
Operating Costs, as provided above, shall be 1/12th of the annual amount.

                 22.03  Projections.  For purposes of calculating Operating
Costs for any Adjustment Year, Landlord may make reasonable estimates,
forecasts or projections (collectively, the "Projections") of Operating Costs
for such Adjustment Year.  Not less than ten (10) days prior to each Adjustment
Date, Landlord shall deliver to Tenant a written statement setting forth the
Projections of Operating Costs for the Adjustment Year in which such Adjustment
Date occurs and providing a calculation of the increase in installments of
Monthly Base Rent to become effective as of said Adjustment Date; provided,
however, that the failure of Landlord to provide any such statement shall not
relieve Tenant from its obligation to continue to pay Operating Costs at the
rate then in effect under this Lease, and if and when Tenant receives such
statement from Landlord, Tenant shall pay any increases in Operating Costs
reflected thereby effective retroactively to the most recently preceding
Adjustment Date.  Landlord shall further deliver to Tenant, not later than ten
(10) days prior to the Commencement Date, a written statement setting forth the
Projections of Operating Costs for that portion of the Term occurring prior to
the first Adjustment Date.

                 22.04  Readjustments.  On or about April 1st following the end
of each Adjustment Year, or at such later time as Landlord shall be able to
determine the actual amounts of Operating Costs for the Adjustment Year last
ended, Landlord shall notify Tenant in writing of such actual amounts.  If such
actual amounts exceed the Projections for such Adjustment Year, then Tenant
shall, within thirty (30) days after the date of such written notice from
Landlord, pay to Landlord its proportionate share of the excess based on the
Net Rentable Area of the Premises as compared to the total Rentable Square
Footage of the Building.  The obligation to make such payments shall survive
the expiration or earlier termination of the Term.  If the total





                                       19
<PAGE>   22
Operating Costs paid by Tenant during such Adjustment Year exceeds the amount
thereof payable for such year based upon actual Operating Costs for such
Adjustment Year, then Landlord shall credit such excess to installments of
Operating Costs payable after the date of Landlord's notice until such excess
has been exhausted, or if this Lease shall expire prior to full application of
such excess, Landlord shall pay to Tenant the balance thereof not theretofore
applied against Rent.  No interest or penalties shall accrue on any amounts
which Landlord is obligated to credit or to pay Tenant by reason of this
Section.

                 22.05  Partial Occupancy.  For purposes of determining the
initial and any adjusted amounts of Tenant's share of Operating Costs for any
Adjustment Year prior to the first full calendar year in which at least
ninety-five percent (95%) of the rentable area of the Building is occupied by
tenants, the amount of Taxes and Operating Costs for such Adjustment Year may,
at Landlord's option, be increased to the amount that would have been payable
had there been at least ninety-five percent (95%) occupancy in the Building
during such Adjustment Year.

                 22.06  Books and Records.  Landlord shall maintain books and
records showing Operating Costs in accordance with sound accounting and
management practices and shall retain such books and records for a period of
one (1) year after the end of each calendar year during which such Operating
Costs were paid or incurred.  The books and records shall be available to
Tenant for inspection upon prior reasonable notice.

                 22.07  No Decreases in Monthly Base Rent.  Notwithstanding
anything to the contrary contained in this Lease, Monthly Base Rent shall not
be adjusted or decreased below the amount set forth in 1.01I.


                            23.  REAL ESTATE BROKERS

                 Tenant represents that, except for the broker, if any, set
forth in 1.01L hereof as Tenant's Broker, Tenant has not dealt with any real
estate broker, salesperson, or finder in connection with this Lease, and no
such person initiated or participated in the negotiation of this Lease, or
showed the Premises to Tenant.  Tenant agrees to indemnify and hold harmless
Landlord and the Manager from and against any and all liabilities and claims
for commissions and fees arising out of a breach of the foregoing
representation.  Landlord shall only be responsible for the payment of all
commissions to the broker, if any, specified in this Article 23, based upon the
leasing commission policy of Landlord applicable to the Complex as of the date
of this Lease.


                       24.  SUBORDINATION AND ATTORNMENT

                 24.01  Subordination.  This Lease and Tenant's rights under
this Lease are subject and subordinate to any ground lease or underlying lease,
first mortgage, first deed of trust or other first lien encumbrance or
indenture, together with any renewals, extensions, modifications,
consolidations, and replacements of them, which now or at any subsequent time
affect the Premises or any interest of Landlord in the Premises or Landlord's
interest in this Lease and the estate created by this Lease (except to the
extent that any such instrument expressly provides that this Lease is superior
thereto).  This provision will be self-operative and no further instrument of
subordination will be





                                       20
<PAGE>   23
required in order to effect the same.  Nevertheless, Tenant will execute,
acknowledge and deliver to Landlord, at any time and from time to time, upon
demand by Landlord, such documents as may be requested by Landlord, and ground
landlord or underlying lessor or any mortgagee, or any holder of a deed of
trust or other instrument described in this Section, to confirm or effect any
such subordination.  If Tenant fails or refuses to execute, acknowledge, and
deliver any such document within twenty (20) days after written demand,
Landlord, its successors and assigns will be entitled to execute, acknowledge,
and deliver any such document on behalf of Tenant as Tenant's attorney-in-fact.
Tenant constitutes and irrevocably appoints Landlord, its successors and
assigns, as Tenant's attorney-in-fact to execute, acknowledge, and deliver on
behalf of Tenant any document described in this paragraph.

                 24.02  Attornment.  If any holder of any mortgage, indenture,
deed of trust, or other similar instrument described in 24.01 succeeds to
Landlord's interest in the Premises, Tenant will pay to it all rents
subsequently payable under this Lease.  Tenant will, upon request of any one so
succeeding to the interest of Landlord, automatically become the Tenant of, and
attorn to, such successor in interest without change in this Lease.  Such
successor in interest will not be bound by (1) any payment of rent for more
than one month in advance, or (2) any amendment or modification of this Lease
made without its written consent, or (3) any claim against Landlord arising
prior to the date on which such successor succeeded to Landlord's interests, or
(4) any claim or offset of Rent against the Landlord.  Upon request by such
successor in interest and without cost to Landlord or such successor in
interest, Tenant will execute, acknowledge, and deliver an instrument or
instruments confirming the attornment.  The instrument of attornment will also
provide that such successor in interest will not disturb Tenant in its use of
the Premises in accordance with this Lease so long as Tenant is not in default
under this Lease.  If Tenant fails or refuses to execute, acknowledge, and
deliver any such instrument within twenty (20) days after written demand, such
successor in interest will be entitled to execute, acknowledge, and deliver any
such document on behalf of Tenant as Tenant's attorney-in-fact.  Tenant
constitutes and irrevocably appoints such successor in interest as Tenant's
attorney-in-fact to execute, acknowledge and deliver on behalf of Tenant any
document described in this Section.


                                  25.  NOTICES

                 All notices required or permitted to be given under this Lease
shall be in writing and shall be deemed given and delivered, whether or not
received, when deposited in the United States Mail, postage prepaid and
properly addressed, certified mail, return receipt requested, at the addresses
shown in 1.01 hereof or such other address as either party may designate for
itself from time to time by written notice to the other party.  In addition,
any notice may be given by hand delivery to the notice address of either party
with a signed receipt obtained.


                               26.  MISCELLANEOUS

                 26.01  Entire Agreement.  This Lease and the Exhibits and
Schedules attached hereto contain the entire agreement between Landlord and
Tenant concerning the Premises and there are no other agreements, either oral
or written.  This Lease may not





                                       21
<PAGE>   24
be altered, changed or amended except by instrument in writing signed by
Landlord and Tenant.

                 26.02  No Option.  The execution of this Lease by Tenant and
delivery of same to Landlord or Manager does not constitute a reservation of or
option for the Premises or an agreement to enter into a Lease and this Lease
shall become effective only if and when Landlord executes and delivers same to
Tenant; provided, however, the execution and delivery by Tenant of this Lease
to Landlord or the Manager shall constitute an irrevocable offer by Tenant to
lease the Premises on the terms and conditions herein contained, which offer
may not be withdrawn or revoked for thirty (30) days after such execution and
delivery.  If Tenant is a corporation, it shall, if requested by Landlord,
deliver to Landlord certified resolutions of Tenant's directors authorizing
execution and delivery of this Lease and the performance by Tenant of its
obligations hereunder.  If Tenant is a partnership, every general partner
thereof shall execute this Lease, unless a lesser number is deemed sufficient
in the reasonable opinion of Landlord's legal counsel.

                 26.03  Accord and Satisfaction.  No payment by Tenant or
receipt by Landlord of a lesser amount than any installment or payment of Rent
due shall be deemed to be other than on account of the amount due, and no
endorsement or statement on any check or any letter accompanying any check or
payment of Rent shall be deemed an accord and satisfaction, and Landlord may
accept such check or payment without prejudice to Landlord's right to recover
the balance of such installment or payment of Rent or pursue any other remedies
available to Landlord.  No receipt of money by Landlord from Tenant after the
termination of this Lease or Tenant's right of possession of the Premises shall
reinstate, continue or extend the Term.

                 26.04  Binding Effect.  This Lease shall be binding upon and
inure to the benefit of Landlord and Tenant and their respective heirs, legal
representatives, successors and permitted assigns.

                 26.05  Force Majeure.  Neither party hereto shall be deemed in
default with respect to any of the terms, covenants and conditions of this
Lease, if such party fails to timely perform same and such failure is due in
whole or in part to any strike, lockout, labor trouble (whether legal or
illegal), civil disorder, inability to procure materials, failure of power,
restrictive governmental laws and regulations, riots, insurrections, war, fuel
shortages, accidents, casualties, Acts of God, acts caused directly or
indirectly by the other party (or such other party's agents, employees or
invitees) or any other cause beyond the commercially reasonable control of the
non-performing party; provided, however, that nothing herein shall excuse
Tenant's failure to pay Monthly Base Rent or any other charges due to Landlord
hereunder.

                 26.06  Captions.  The Article and Section captions of this
Lease are inserted only as a matter of convenience and in no way define, limit,
construe, or describe the scope or intent of such Articles and Sections.

                 26.07  Applicable Law.  This Lease shall be construed in
accordance with the laws of the State of Wisconsin.

                 26.08  Time.  Time is of the essence with respect to this
Lease and the performance of all obligations hereunder.

                 26.09  Landlord's Right to Perform Tenant's Duties.  If Tenant
fails timely to perform any of its duties under this Lease or the Work Letter,
Landlord shall have the right (but not the obligation), after the expiration of
any grace period elsewhere under this Lease or the Work Letter expressly
granted to Tenant for the performance of such duty, to perform such duty on
behalf and at the expense of Tenant without further prior notice to Tenant, and
all sums expended or expenses incurred by Landlord in performing such duty
shall be deemed to be additional Rent under this Lease and shall be due and
payable upon demand by Landlord.

                 26.10  Relationships.  The relationship between Landlord and
Tenant is that of landlord and tenant and nothing herein shall be construed to
give rise to any other relationship including, without limitation, a creditor
and debtor relationship.

                 26.11  Invalidity.  If any term(s), condition(s), covenant(s),
clause(s) or provision(s) herein contained shall operate or would prospectively
operate to invalidate this Lease in whole or in part, then only such term(s),
condition(s), covenant(s), clause(s), and/or provision(s) shall be held for
naught as though not herein contained, and the remainder of this Lease shall
remain operative and in full force and effect.

                 26.12  Limitation of Landlord's Liability.  Anything contained
in this Lease to the contrary notwithstanding, Tenant agrees that it shall look
solely to the estate and property of the Landlord in the Building and the land
thereunder for the collection of any judgment (or other judicial process)
requiring the payment of money by Landlord for any default or breach by
Landlord of any of its obligations under this Lease, subject, however, to the
prior rights of any ground or underlying landlord or the holder of any mortgage
covering the Building or of Landlord's interest therein.  No other assets of
the Landlord shall be subject to levy, execution or other judicial process for
the satisfaction of Tenant's claim.  This provision shall not be deemed,
construed or interpreted to be or constitute an agreement, express or implied,
between Landlord and Tenant that the Landlord's interest hereunder and in the
Building shall be subject to impressment of an equitable lien or otherwise.
Nothing herein contained shall be construed to limit any right of injunction
against the Landlord, where appropriate.

                 26.13  Transfer of Landlord's Interest.  In the event of the
sale, assignment or transfer by Landlord of its interest in the Building or in
this Lease (other than a collateral assignment to secure a debt of Landlord) to
a successor in interest who expressly assumes the obligations of Landlord
hereunder, Landlord shall thereupon be released or discharged from all of its
covenants and obligations hereunder, except such obligations as shall have
accrued prior to any such sale, assignment or transfer; and Tenant agrees to
look solely to such successor in interest of Landlord for performance of such
obligations.  Any securities given by Tenant to Landlord to secure performance
by Tenant of its obligations hereunder may be assigned by Landlord to such
successor in interest of Landlord; and, upon acknowledgement by such successor
of receipt of such security and its express assumption of the obligation to
account to Tenant for such security in accordance with the terms of the Lease,
Landlord shall thereby be discharged of any further obligation relating
thereto.  Landlord's assignment of the Lease or of any or all of its rights
herein shall in no manner affect Tenant's obligations hereunder.  Tenant shall
thereafter attorn and look to such assignee, as Landlord, provided Tenant has
first received written notice of such assignment of Landlord's





                                       23

interest.  Landlord shall have the right to freely sell, assign or otherwise
transfer its interest in the Building and/or this Lease.

                 26.14  Parking.  Throughout the Lease Term, Tenant shall have
the right to lease from Landlord at the rate then being charged by Landlord, as
adjusted from time to time, two (2) unassigned parking space(s) in the parking
structure located in the 100 East Wisconsin Avenue building and three (3)
unassigned parking spaces in the parking structure located in the 720 North
Water Street building; provided, however, that a cancellation by Tenant of the
use of such parking space(s) shall constitute a waiver by Tenant of any further
right to lease such space(s).  Subject to the availability of parking spaces in
the parking structure serving the Building from time to time, Tenant shall have
the right to lease one or more additional unassigned parking spaces from the
Landlord at the rate then being charged by Landlord, as adjusted from time to
time, provided, however, Landlord or Tenant may cancel one or more of such
additional unassigned parking spaces upon thirty (30) days written notice to
the other party.

                 26.15  Riders.  Riders One (1) through Two (2) attached hereto
shall be deemed to be a part hereof and are hereby incorporated herein.

                 IN WITNESS WHEREOF, this Lease has been executed as of the 
date set forth in 1.01E hereof.

presence in the Building at any time shall, in the judgment of the Landlord, be
prejudicial to the safety, character, reputation and interests of the Building
or its Tenants may be denied access to the Building or may be ejected
therefrom.  In case of invasion, riot, public excitement or other commotion,
the Landlord may prevent all access to the Building during the continuance of

Building and protection of property in the Building.  The Landlord may require
any person leaving the Building with any package or other object to exhibit a
pass from the Tenant from whose Premises the package or object is being
removed, but the establishment and enforcement of such requirement shall not
impose any responsibility on the Landlord for the protection of any Tenant
against the removal of property from the Premises of the Tenant.  The Landlord
shall in no way be liable to any Tenant for damages or loss arising from the
admission, exclusion or ejection of any person to or from the Tenant's Premises
or the Building under the provisions of this Rule.

                 2.  Landlord reserves the right to exclude or expel from the
Building any person who in the judgment of Landlord is intoxicated or under the
influence of liquor or drugs.

                 3.  Tenants shall not do or permit anything to be done in
their Premises or bring or keep anything therein which will in any way obstruct
or interfere with the rights of other tenants, or do, or permit anything to be
done in their Premises which shall, in the judgment of the Landlord or its
manager, in any other way injure or annoy them, or conflict with the laws
relating to fire, or with the regulations of the fire department or with any
insurance policy upon the Building or any part thereof or any contents therein
or conflict with any of the rules and ordinances of the public building or
health authorities.

                 4.  All electrical equipment used by Tenants shall be U.L.
approved.  Nothing shall be done or permitted in Tenant's Premises, and nothing
shall be brought into or kept in the Premises which would impair or interfere
with any of the Building services or the proper and economic heating, cooling,
cleaning or other servicing of the Building or the Premises.

                 5.  Tenants shall not install or operate any steam or gas
engine or boiler, or carry on any mechanical business, in the Building.  The
use of oil, gas or inflammable liquids for heating, lighting or any other
purpose is expressly prohibited.  Explosives or other articles deemed extra
hazardous shall not be brought into the Building.  Tenants shall not use any
method of heating other than that supplied by the Landlord.

                 6.  Tenants shall give Landlord prompt notice of all accidents

                 7.  Tenants shall use electric, gas and any other form of
energy only from such sources of supply as is furnished in the Building.

                 8.  All deliveries to the Building for or by any Tenant are to

entrances.

                 9.  Furniture, equipment or supplies shall be moved in or out
of the Building only upon the elevator designated by Landlord and then only
during such hours and in such manner as may be prescribed by Landlord.

                 10.  Should any Tenant desire to place in the Building any
unusually heavy equipment, including, but not limited to, large files, safes
and electronic data processing equipment, it shall first obtain written
approval of the Landlord to place such items within the Building, for the use

                                  WORK LETTER

100 EAST WISCONSIN AVENUE JOINT VENTURE ("Landlord") and SYSTEMS & PROGRAMMING
RESOURCES, INC. ("Tenant") are executing simultaneously with this Agreement an
Office Building Lease dated April 19, 1996 pertaining to certain space (the
"Premises") in 100 East Wisconsin Avenue, Milwaukee, Wisconsin.

                 In consideration of the mutual covenants herein contained,
Landlord and Tenant agree as follows:

                 1.  TENANT'S PLANS AND SPECIFICATIONS:

                 A.  Standard Work.  Except to the extent otherwise provided in
Sections 1B and 1C Landlord agrees that, at its sole cost and expense, and
through its architects and engineers, Landlord will furnish all architectural,
mechanical and electrical engineering plans required for the performance of the
work (referred to as "Building Standard Work") described below, including
complete detailed plans and specifications for Tenant's partition layout,
reflected ceiling plan, electrical outlets and switches, telephone outlets and
room finish schedule for Building Standard finishes.

                 B.  Nonstandard Work.  It is understood and agreed that Tenant
may require work (referred to as "Building Nonstandard Work") different from or
in addition to said Building Standard Work.  In such event, any additional
architectural, mechanical and electrical plans and specifications required
shall be furnished at Tenant's sole cost and expense by Landlord's architects
and engineers.

                 C.  Interior Decoration.  It is understood and agreed that any
interior decorating services and the costs of the related work such as
selection of wallpaint colors, and/or wallcoverings, fixtures or carpeting
other than Building Standard, and any or all other decorator items required by
Tenant in the performance of the work referred to above in 1A and 1B, shall be
at Tenant's sole cost and expense.

                 D.  Plan Approval.  It is understood and agreed that all plans
and specifications referred to in 1B and 1C are subject to the Landlord's
approval.  Tenant also agrees that, when requested by Landlord's architects,
Tenant will furnish complete information respecting Tenant's requirements and
that complete plans, specifications and budgets will be prepared according to
the guidelines established in Section 2 below.

                 2.  SPACE PLAN/CONSTRUCTION DOCUMENTATION:

                 A.  Preliminary Planning.  Tenant approved space plans have
been delivered to Landlord.

                 B.  Construction Documentation.  Landlord and Tenant have both
approved the construction documents.  Landlord shall arrange to have Architect
submit ten (10) sets of construction documents to Landlord for contractor
pricing and submission to the Milwaukee Building Inspection Department for
issuance of a building permit.  Upon issuance of a building permit, Landlord
shall then have seven (7) working days to obtain cost of construction.

                 C.  Delays by Tenant.  Landlord has allocated twenty-nine (29)
working days for the completion of the Building





                                      C-1
<PAGE>   37
Standard work, and will have contractual agreements with the general contractor
to this end.  Any delays or time extensions required due to Building
Nonstandard Work will be subject to the provisions of Section 6 below.  Failure
by Tenant to comply with the time frames identified herein shall in no way
relieve Tenant from the previous established Lease Commencement Date.

                 3.  BUILDING STANDARD WORK AT LANDLORD'S COST AND EXPENSE:

                 Landlord agrees, at its sole cost and expense, to furnish and
install all of the Building Standard Work, as set forth in the attached
Schedule A, limited to the quantities specified, as selected and specified by
Landlord, and as indicated on Tenant's final approved plans.

                 4.  BUILDING NONSTANDARD WORK AT TENANT'S COST AND EXPENSE:

                 Provided that Tenant's plans and specifications are furnished
within the time frames provided in Section 2 above, the Landlord shall cause
the Tenant's Building Nonstandard Work to be installed.  At the expense of
Tenant, Landlord shall supply, install and finish, at cost plus fifteen percent
(15%) for coordination by the Landlord, all items of the Building Nonstandard
Work.  Prior to commencing any such work, Landlord shall have received from
Tenant the Expenditure Authorization as outlined in Section 2 above.  If Tenant
fails to approve the Expenditure Authorization within the time frame as
specified, then same shall be deemed disapproved in all respects by Tenant, and
Landlord's contractors shall not proceed with such work.

                 Subsequent to Tenant's approval of the Expenditure
Authorization, the Landlord or its agent will submit a statement to the Tenant,
whereupon ninety percent (90%) of the amounts of such statement will be
immediately due and payable by Tenant to Landlord.  Landlord shall then
commence construction work as authorized.  The balance, together with any other
amount due to Landlord as a result of Tenant change orders, shall be billed
periodically as the work is completed, and Tenant agrees to pay Landlord within
fifteen (15) days of receipt of such invoice.

                 It is further understood that all finished work shall require
the installation of new materials equal in quality to that installed in other
parts of the Building.

                 5.  COMPLETION AND RENTAL COMMENCEMENT DATE:

                 It is agreed that, notwithstanding that date provided in the
Lease for the commencement thereof, Tenant's obligation for the payment of rent
under the Lease shall not commence until Landlord shall have substantially
completed all work to be performed by Landlord as set forth in Section 3
hereof; provided, however, if Tenant's occupancy and use of the Premises shall
be delayed as a result of:  (1) Tenant's failure to comply with the provisions
of Section 2; (2) Tenant's request for materials, finishes or installations of
other than Landlord's standard; (3) Tenant's changes in the approved drawings;
(4) the performance by a person, firm or corporation employed by the Tenant in
the completion of said work; or (5) any other delay chargeable to Tenant, its
agents, employees or independent contractors, then the commencement of the term
of the Lease and the payment of rent thereunder shall commence notwithstanding
any contrary provisions of the Lease, on the expressed commencement date as set
forth in Section 2 of the Lease.  Landlord further agrees that, regardless of
whether the delay in completion of the Premises is caused by





                                      C-2
<PAGE>   38
the Landlord or the Tenant, in the event the Premises is not substantially
completed on or before the commencement date set forth in Section 2 of the
Lease, Landlord shall lease temporary space in the Building (the "Temporary
Space") to Tenant until the Premises is substantially completed; provided,
however, in the event the delay in completion of the Premises is due to a
Tenant delay, Landlord shall only be required to provide the Tenant with the
Temporary Space for thirty (30) days after Tenant's occupancy of the Temporary
Space, and, in the event Tenant occupies the Temporary Space for more than such
thirty (30) day period, such event shall be considered and event of default
under Section 12.01 of the Lease.  The lease of such Temporary Space shall be
on the same terms and conditions as set forth in this Lease except that the
monthly base rent for the Temporary Space shall be calculated as follows:
monthly base rent for the Temporary Space shall equal $10.00 multiplied by the
actual rentable square footage of the Temporary Space divided by 12.  Tenant
shall be responsible to pay monthly base rent for any full or partial month
Tenant occupies the Temporary Space, and, Tenant shall be responsible for all
Operating Costs for the Temporary Space.  Furthermore, Landlord agrees that, in
the event the Premises are not substantially completed on or before the
commencement date set forth in Section 2 of the Lease due to a delay caused by
Landlord and, as a direct result thereof, Tenant occupies the Temporary Space,
Landlord shall reimburse Tenant for the reasonable cost of moving Tenant from
the Temporary Space to the Premises (including, but not limited to, the cost of
telephone and computer cabling relocation).

                 6.  CHANGES, ADDITIONS OR DELETIONS IN WORKING DRAWINGS:

                 If Tenant shall request any change, addition or alteration in
working drawings, subsequent to the approval of Landlord and Tenant, then
Tenant shall have such working drawings prepared, and shall promptly reimburse
Architect for the costs thereof.  Upon completion of the revisions, Landlord
shall notify Tenant, in writing, of the estimated costs which will be
chargeable to the Tenant by reason of such change, addition or deletion.
Tenant shall, within three (3) working days, notify Landlord in writing whether
it desires to proceed with such change, addition or deletion, and, in the
absence of such written authorization, Landlord shall not be obligated to
continue work on Tenant's Premises, and Tenant shall be chargeable with any
delay in the completion of the Premises resulting therefrom, and Rent shall
commence to accrue as set forth in Paragraph 3 of the Lease.

such reasonable rules and regulations governing the use thereof as Sublessor
may from time to time establish, which rules and regulations shall not
unreasonably interfere with Sublessee's use and enjoyment of the Subleased
Premises, Sublessor's first floor entrance and reception area and the kitchen
and  conference room presently located within Space B.  Sublessor and Sublessee
shall each indemnify and hold harmless the other against any loss, claim,
liability, cost or expense, including reasonable attorneys' fees and expenses,
arising out of the use or possession of the areas in Space B used in common by
Sublessor and Sublessee prior to the Space B Commencement Date.

         3.      DEMISE OF SUBLEASED PREMISES.  Sublessor hereby subleases and
demises to Sublessee, and Sublessee hereby accepts from Sublessor, on the terms
and conditions set forth above and hereinafter, the Subleased Premises.

         4.      RENT.

                 (a)      For each Lease Year (defined below) during the Term
of this Sublease, Sublessee shall pay to Sublessor, as rent for the Subleased
Premises an annual sum, determined as follows (the "Base Rent"):
                          
                          During the first Lease Year:   $11.00 multiplied by 
                                                         the number of square 
                                                         feet contained in the 
                                                         Subleased Premises;

                          During the second Lease Year:  $11.50 multiplied
                                                         by the number of
                                                         square feet contained
                                                         in the Subleased 
                                                         Premises;





                                       2
<PAGE>   3


                          During the third Lease Year:  $12.00 multiplied by
                                                        the number of square
                                                        feet contained in the 
                                                        Sublease Premises;

                          During the fourth Lease Year: $12.50 multiplied by
                                                        the nuber of square feet
                                                        contained in the 
                                                        Subleased Premises;

                          During the fifth Lease Year:  $13.00 multiplied by
                                                        the number of square 
                                                        feet contained in the 
                                                        Sublease Premises;



                 As used herein, the term "Lease Year" shall mean the period of
365 consecutive days beginning on the Commencement Date and ending on the day
before the first anniversary thereof, and each subsequent period of 365
consecutive days, except that the last Lease Year shall end on the last day of
the Term.  Subject to the provisions of subparagraph 4(c) hereof, the Base Rent
shall be paid in equal monthly installments, in advance, beginning on the
Commencement Date and continuing on the first day of each calendar month during
the Term thereafter.

                 (b)       The Base Rent and all other sums payable hereunder
(such other sums being referred to herein as "Additional Rent") shall be paid
to Sublessor without deduction, set off, prior notice or demand, except as
provided in paragraph 13(c) hereof, in lawful money of the United States of
America, at Sublessor's office at 815 Commerce Drive, Oak Brook, Illinois
60521, or at such other place as Sublessor may specify from time to time by
written notice to Sublessee.

                 (c)      Sublessee shall pay the monthly installment of Base
Rent due for the first full calendar month of the Term to Sublessor
concurrently with execution and delivery of this Sublease.  If the Commencement
Date should occur on a day other than the first day of a calendar month, or if
the last day of the Term should occur on a day other than the last day of a
calendar month, then, the Base Rent and Additional Rent payable for such
fractional month shall be prorated on a daily basis.

         5.      OPERATING COSTS.

                 (a)      In addition to the Base Rent provided for in
paragraph 4 above, and in addition to any other Additional Rent payable by
Sublessee hereunder, Sublessee shall reimburse Sublessor for Sublessee's
Proportionate Share (as hereinafter defined) of the costs incurred by Sublessor
for Taxes and Operating Expenses payable to the Master Landlord, as provided in
the Master Lease (collectively "Base Expenses"), to the extent that such Base
Expenses exceed those payable by Sublessor in respect of the calendar year 1996
("Excess Expenses").





                                       3
<PAGE>   4


                 (b)      Sublessee's Proportionate Share shall equal the ratio
of the number of square feet contained within the Subleased Premises from time
to time to the number of square feet contained within the entire Master Leased
Premises, expressed as a percentage.

                 (c)      Sublessee shall pay Sublessee's Proportionate Share
of Excess Expenses for each calendar year, or part thereof during the Term,
less the amount of any monthly estimated payments thereof made by Sublessee
pursuant to the requirements of subparagraph 5(d) below, to  Sublessor within
30 days after receipt of Sublessor's statement thereof, which statement shall
include Sublessor's calculation of Sublessee's Proportionate Share of such
Excess Expenses, set forth in reasonable detail, a copy of the annual statement
of Taxes and Operating Expenses for such calendar year, as furnished to
Sublessor by the Master Landlord, and an accounting by Sublessor of the monthly
estimated payments of Excess Expenses for such calendar year received by
Sublessor.

                 (d)      Sublessor shall have the right from time to time, but
not more frequently than once in any calendar year, to prepare reasonable
estimates of the Excess Expenses payable by Sublessee hereunder and to require,
by written notice to Sublessee, that Sublessee pay such estimated amounts to
Sublessor, in monthly installments, in advance, together with Sublessee's
payments of Base Rent.  All such monthly estimated payments shall be credited
against the Excess Expenses payable by Sublessee for the calendar year to which
such monthly estimated payments pertain.  In the event Sublessee's monthly
estimated payments of Excess Expenses for any calendar year are greater than
the Excess Expenses payable by Sublessee for such calendar year, Sublessee
shall be entitled to credit the overpayment against the monthly estimated
payments of Excess Expenses next coming due hereunder, or, if such overpayment
is of Excess Expenses for the calendar year in which the Term ends and no
further sums are due from Sublessee to Sublessor under this Sublease, Sublessor
shall refund such overpayment to Sublessee within 30 days after the time at
which the amount of the Excess Expenses payable by Sublessee for such final
calendar year has been determined.

         6.      ELECTRICITY.     Sublessor has advised Sublessee that
Sublessor's first floor space is separately metered for electricity.  Sublessee
shall be responsible for and shall pay to Sublessor from time to time within 10
days after receipt of Sublessor's statement thereof, Sublessee's Share (as
defined below) of the cost of electricity consumed within such first floor
space ("Electricity Expense"), as determined by the statements to Sublessor
from the public utility providing such electricity.  During the period
beginning of the Commencement Date and ending on the Space B Commencement date,
Sublessee's Share of the Electricity Expense shall be forty-three and nine
tenths percent (43.9%), which, Sublessor, represents is the ratio of the number
of square feet within the Subleased Premises to the number of square feet
contained within the Sublessor's first floor space.  In the event either
Sublessor or Sublessee shall use electricity in extraordinary amounts, the
parties shall make an equitable allocation based on such use.  If no such
allocation can be agreed upon, then a final determination shall be made by a
representative of the public utility for electric service.  From and after the
Space B Commencement Date, Sublessee shall be responsible for the entire
Electricity Expense and shall contract directly with the public utility for
electric service to the Subleased Premises.

         7.      TERM.  The term of this Sublease ("Term") shall begin on the
Commencement Date and shall end on September 30, 2002, unless sooner terminated
by reason of Sublessee's default or by reason of the exercise by Sublessor or
Sublessee of a termination option, as provided in paragraph 11 hereof.

         8.      CONDITION OF SUBLEASED PREMISES.  Sublessee agrees to accept
the Subleased Premises in their "as is" condition, and Sublessee acknowledges
that Sublessor has not agreed and is under no obligation to make any repairs,
replacements or improvements to the Subleased Premises and that Sublessor has
made no representation or warranty concerning the condition of the subleased
premises or their suitability for Sublessee's proposed use.

         9.      USE.  Sublessee shall use the Subleased Premises for the uses
permitted under the Master Lease (excluding the use referred to in the insert
on page 4-a of the Master Lease) and for no other purpose.

         10.     ALTERATIONS AND IMPROVEMENTS.  Sublessee shall not make any
alterations or improvements to the Subleased Premises without the prior written
consent of Sublessor.  Sublessor agrees that Sublessor will not withhold or
delay its consent to a proposed alteration or improvement unreasonably, but (i)
Sublessor may withhold Sublessor's consent to a particular alteration or
improvement notwithstanding that the Master Landlord has consented thereto, and
(ii) Sublessor may condition its consent to a particular alteration or
improvement upon (A) Master Landlord's consent thereto, as provided in the
Master Lease, and (B) Sublessee's agreement  to remove such alteration or
improvement at the end of the Term and restore the Subleased Premises to their
condition prior to the construction of such alteration or improvement, all at
Sublessee's sole expense.  Further, Sublessor may require that Sublessee
deliver to Sublessor a cash deposit or other security acceptable to Sublessor,
in an amount equal to the cost of any such removal and restoration, as
reasonably determined by Sublessor, estimated to exceed $5,000.00.

         11.     TERMINATION OPTIONS.

                 (a)      Sublessee shall have a one time right (the "First
Termination Option") to terminate this Sublease, effective as of January 1,
2001, by delivering a written notice of such termination to Sublessor (the
"First Termination Notice") on or prior to July 1, 2000, accompanied by
Sublessee's payment to Sublessor in an amount equal to fifty percent (50%) of
the Base Rent payable for the period from January 1, 2001 through the end of
the Term (the "First Termination Fee").  In the event Sublessee serves the
First Termination Notice, as provided above, and delivers to Sublessor the
First Termination Fee, this Sublease shall terminate on December 31, 2000, and
Sublessee shall, on or before such date, vacate the Subleased Premises and
surrender possession thereof to Sublessor, in the manner and condition provided
in the Master Lease.

                 (b)      In addition to the First Termination Option,
Sublessee shall have a one time right (the "Second Termination Option") to
terminate this Sublease, effective as of January 1, 2002, by delivering a
written notice of such termination to Sublessor (the "Second Termination
Notice")





                                       5
<PAGE>   6

on or prior to July 1, 2001, accompanied by Sublessee's payment to Sublessor in
an amount equal to seventy-five percent (75%) of the Base Rent payable for the
period from January 1, 2002 through the end of the Term (the "Second
Termination Fee").  In the event Sublessee serves the Second Termination
Notice, as provided above, and delivers to Sublessor the Second Termination
Fee, this Sublease shall terminate on December 31, 2001, and Sublessee shall,
on or before such date, vacate the Subleased Premises and surrender possession
thereof to Sublessor, in the manner and condition provided in the Master Lease.

         12.     BROKERAGE FEES.  Sublessee shall pay all brokerage fees
payable by reason of this Sublease to Strobeck Real Estate, which is
Sublessee's broker.  Sublessor represents to Sublessee that Sublessor has
dealt with no broker or finder in connection with this Sublease, and Sublessee
represents to Sublessor that Sublessee has dealt with no broker or finder in
connection with this Sublease other than Strobeck Real Estate.

         13.     MASTER LEASE.

                 (a)        This Sublease is subject to, and Sublessee accepts
subject to, all the terms, covenants, provisions, conditions and agreements
contained in the Master Lease and the matters, if any to which the Master Lease
is subject and subordinate.  This Sublease shall also be subject to, and
Sublessee accepts subject to, any amendments and supplements to the Master
Lease made subsequent to this Sublease so long as any such amendments and
supplements shall not adversely affect Sublessee's quiet enjoyment of Subleased
Premises.  Notwithstanding the preceding sentence to the contrary, no consent,
waiver, amendment, or other change by Master Landlord of Sublessor's
obligations and liabilities as tenant under the Master Lease shall reduce,
limit or expand Sublessee's obligations and liabilities to Sublessor hereunder
or diminish Sublessee's rights hereunder unless Sublessee, Sublessor and Master
Landlord shall have agreed in writing that such consent, waiver, amendment or
change shall be effective hereunder.  Except as set forth in subparagraph (b)
below, the terms and conditions of the Master Lease are incorporated in this
Sublease as though fully set forth herein, and, except as set forth below,
Sublessee shall perform, observe and be bound by all of the terms and
conditions of the Master Lease to be performed and observed by the Tenant
thereunder, insofar as the same are applicable to the Subleased Premises;
Sublessor shall perform, observe and be bound by, or take commercially
reasonable measures to cause the Master Landlord to perform and observe, all of
the terms and conditions of the Master Lease to be performed or observed by the
Landlord thereunder, insofar as the same are applicable to the Subleased
Premises; Sublessee shall have, as to Sublessor, all of the rights and benefits
arising and accruing to the Tenant under the Master Lease; and Sublessor shall
have, as to Sublessee, all of the rights and benefits arising or accruing to
the Landlord under the Master Lease.  Notwithstanding the foregoing, Sublessor
shall not be liable to Sublessee for performance or non-performance of the
obligations of Master Landlord under the Master Lease, and Sublessee shall look
solely to and hold solely responsible the Master Landlord for the performance
of such obligations.  If Master Landlord shall default in the performance of
any of its obligations under the Master Lease with respect to the Subleased
Premises, Sublessee shall have the right to take such action in its own name
and, for that purpose and only to such extent, all of the rights of Sublessor
under the Master Lease hereby are conferred upon and assigned to Sublessee, and
Sublessee hereby is subrogated to such





                                       6
<PAGE>   7

rights to the extent that the same shall apply to the Subleased Premises.  If
and to the extent that any of Master Landlord's obligations under the Master
Lease are required to be performed only when or to the extent requested by
Sublessor (and are not otherwise covered by an agreement among Master Landlord,
Sublessor and Sublessee), Sublessor shall endorse and forward Sublessee's
requests therefor to Master Landlord or, upon Sublessee's written request in
each case, Sublessor shall permit Sublessee to submit such requests to Master
Landlord in Sublessor's name and Sublessor shall deliver to Sublessee such
documentation, including without limitation an irrevocable power-of-attorney
coupled with an interest, for such limited purpose, as shall be reasonably
necessary to effectuate such requests. In the event of conflict between any
provision of this Sublease and a provision of the Master Lease, this Sublease
shall, as between Sublessor and Sublessee, control.

                 (b)      The following provisions of the Master Lease are not
incorporated herein and shall not apply to this Sublease:

                          (i)     The description of the Premises, together
         with references to components of the Master Lease Premises including,
         without limitation, the Initial Office Space and the Computer Space;

                          (ii)    The Term;

                          (iii)   Sections 3 and 4, pertaining to Base Rent and
         Additional Rent , but not pertaining to the definitions of Taxes and
         Operating Expenses (including the exclusions thereto) or added
         provisions granting tenant certain rights relating to the auditing of
         books;

                          (iv)    All provisions pertaining to construction of
         improvements by the Landlord, including, without limitation, Exhibit B
         and the attachment thereto;

                          (v)     Section 7B, pertaining to billing for
         electricity;

                          (vi)    The second grammatical paragraph of page 9a;

                          (vii)   Sections 11A and 11B, pertaining to
         insurance;

                          (viii)  Sections 26 and 27, pertaining to security
         deposit and real estate brokers;

                          (ix)    Page 11a;

                          (x)     Addendum to Lease;

                          (xi)    Lease Amendment Agreement;





                                       7
<PAGE>   8


                          (xii)   All exhibits and attachments related to any
          of the foregoing inapplicable provisions.

                 (c)      Sublessor and Sublessee agree, each with the other,
that neither will take or permit any action or fail to perform or observe any
obligation, which causes an event of default under the Master Lease and/or
causes the Master Lease to be terminated or forfeited, and each shall indemnify
the other and hold the other harmless from and against any and all claims,
demands, suits, costs, expenses, damages and liabilities, including reasonable
attorneys' fees, arising by reason of any act or omission on the part of the
indemnifying party which causes the Master Lease to be terminated or forfeited.
Sublessor shall, promptly upon receipt, deliver to Sublessee copies of all
notices of default under the Master Lease which have been delivered to
Sublessor.  In the event that Sublessor defaults in any payment or performance
obligation contained in the Master Lease, Sublessee may, in addition to any
other remedies which Sublessee may have by reason of such default, but shall
not be obligated to, cure such default under the terms of the Master Lease, if
permitted so to cure by Master Landlord, and the amount of any payment made or
cost or expense to cure such default shall be treated as a sum of money
advanced by Sublessee to Sublessor and shall be repayable by Sublessor to
Sublessee within 30 days of demand.  If said sum so advanced is not so paid
within said 30 day period, Sublessee shall have the right to deduct such amount
from any installment of Base Rent or other amounts next becoming due and
payable under this Sublease.

         14.     EVENTS OF DEFAULT.

                 (a)      Each of the following shall constitute an event of
default by Sublessee under this Sublease and shall entitle Sublessor to
exercise any and all remedies available to the Master Landlord under the Master
Lease and/or available to Sublessor by operation of law:

                          (i)     Sublessee shall fail to pay when due any
         monthly installment of Base Rent or Excess Expenses, or shall fail to
         pay when due any other sum payable hereunder, and  such failure shall
         continue for five days after delivery to Sublessee of Sublessor's
         written notice thereof;

                          (ii)    Sublessee shall fail to observe or perform
         any other term or condition to be observed or performed by Sublessee
         hereunder or under the Master Lease, and such failure shall continue
         for 30 days after delivery to Sublessee of Sublessor's written notice
         thereof, unless such failure of performance, by its nature, cannot be
         cured within 30 days, in which event, such failure of performance
         shall be deemed cured if Sublessee commences to cure the same within
         such 30 day period and completes such cure as soon as reasonably
         practicable; and

                          (iii)   Sublessee shall file a petition in bankruptcy
         or avail itself of any other state or federal law providing for the
         relief of debtors.





                                       8
<PAGE>   9


                 (b)      In the event of a breach by Sublessor of any of the
covenants, agreements, terms or conditions which are contained herein,
Sublessee may exercise any remedies available to Sublessee herein, or any other
legal remedies available to Sublessee with respect to a default this Sublease
or any act, omission, negligence or willful misconduct of Sublessor or its
agents, servants, employees, officers, contractors and invitees, whether at law
or in equity, all such rights and remedies being cumulative and the exercise of
any one of which shall not exclude any other.  Sublessee shall use reasonable
efforts to mitigate any damages it may suffer by reason of a default by
Sublessor  hereunder.

         15.     CONSENT OF MASTER LANDLORD.  Sublessee acknowledges that,
under the terms of the Master Lease, this Sublease requires the prior written
consent of the Master Landlord (the "Master Landlord's Consent").  Sublessor
agrees to use reasonable diligence to obtain Master Landlord's Consent,
promptly upon delivery to Sublessor of at least three counterparts of this
Sublease, duly executed by Sublessee.  If Sublessor has not received Master
Landlord's Consent within 30 days after receipt of such executed counterparts
of this Sublease from Sublessee, either Sublessor or Sublessee shall have the
right, by written notice to the other party, to elect to terminate this
Sublease.

         16.     ASSIGNMENT AND SUBLETTING.

                 (a)      Sublessee shall not mortgage, pledge, hypothecate or
otherwise encumber all or any  part of its interest under this Sublease.  In
addition, Sublessee shall not assign this Sublease or any of its rights
hereunder, or sublet all or any part of the Subleased Premises, or suffer or
permit the use or occupancy of all or any part of the Subleased Premises by any
party other than Sublessee, without  in each instance requesting and obtaining
the prior written consent of Sublessor and Master Landlord..  Any request for
Sublessor's consent to any proposed assignment, subletting or use of the
Subleased Premises by a party other than Sublessee (each, a "Transfer") shall
be in writing, setting forth in reasonable detail the terms of the proposed
Transfer and including copies of the proposed assignment or sublease relating
thereto, as well as reasonable information concerning the identity, financial
strength and business of the proposed Assignee, Sublessee or other occupant of
the Subleased Premises.  In addition, Sublessee shall furnish promptly any
further information concerning the proposed Transfer which Sublessor may
reasonably request.

                 (b)      Sublessor agrees that it will not withhold or delay
unreasonably its consent to a proposed Transfer; provided, however, that
Sublessor may withhold its consent to any Transfer which (i) is not consented
to by the Master Landlord, if such Transfer, under the terms of the Master
Lease, requires the consent of the Master Landlord thereto, or which (ii) in
the reasonable judgment of Sublessor  would cause Sublessor to be in breach of
the Master Lease.  If Sublessor consents to any Transfer, Sublessee shall enter
into and effect such Transfer only upon terms and conditions consistent with
Sublessee's request for Sublessor's consent, the information furnished in
connection with such request and any conditions to Sublessor's consent imposed
by Sublessor, and Sublessee shall further enter





                                       9
<PAGE>   10

into and cause the transferee to enter into any and all agreements prepared by
Sublessor or its attorneys, as may be appropriate to implement any amendment to
this Sublease required by such Transfer and/or to satisfy any of the conditions
to Sublessor's consent.  No consent of Sublessor to any Transfer shall release
or be construed as releasing any obligation of Sublessee under this Sublease,
except if and to the extent such consent by Sublessor shall expressly release
or modify any such obligation.  Sublessee shall pay to Sublessor on demand,
Sublessor's reasonable costs incurred in connection with each request by
Sublessee for consent to a Transfer, including the reasonable fees and expenses
of Sublessor's attorneys.

                 (c)      Notwithstanding the foregoing to the contrary,
Sublessee may, without Sublessor's consent, assign, transfer or sublet its
entire interest in this Sublease, the leasehold estate created hereby and the
Subleased Premises to any of the following (each a "Permitted Transferee"), (i)
any successor to Sublessee resulting from a merger or consolidation with, of or
into Sublessee, (ii) any entity (including any parent) that controls Sublessee
or any entity (including any affiliate) that is under the common control of or
with Sublessee or is acquired by Sublessee, its parent or affiliate,  or (iii)
any entity that acquires all or substantially all of the assets of Sublessee,
or that acquired a material portion of Sublessee's business; and provided,
further, the sale, transfer or exchange of Sublessee's stock or the stock of
any entity described in (i), (ii) or (iii), on a nationally recognized exchange
shall not be or be deemed to be an assignment or transfer or a subletting of
the sublessee's interest in this Sublease, the leasehold estate hereby created
or of the Subleased Premises.

         17.     EXPANSION OPTION.

                 (a)      In the event Sublessor elects to offer for sublease
Sublessor's space located on the second floor of the Building, which, for all
purposes of this Sublease, Sublessor and Sublessee agree contains 15,954 square
feet (the "Second Floor Space"), Sublessee shall have an option, on the terms
and conditions set forth in this paragraph, to add the Second Floor Space to
the Subleased Premises, for a term coterminous with the Term of this Sublease.
Sublessor shall, prior to offering the Second Floor Space to others, notify
Sublessee of the availability of the Second Floor Space by a written notice
(the "Offer Notice"), delivered to Sublessee at least 120 days prior to the
date on which the Second Floor Space will be available for occupancy (the
"Second Floor Delivery Date").  Sublessor's Offer Notice shall set forth
Sublessor's reasonable, good faith estimate of the base rent and other economic
terms on which Sublessor could sublease the Second Floor Space to an unrelated
third party for a term equal to the then unexpired portion of the Term of this
Sublease and in the condition in which Sublessor is offering the Second Floor
Space (which the parties contemplate will be "as-is") (collectively, the
"Second Floor Terms").

                 (b)      Provided that no event of default on the part of
Sublessee is then existing, and provided that no such event of default occurs
prior to the Second Floor Delivery Date, Sublessee shall have the right
exercisable by written notice ("Acceptance Notice") to Sublessor within five
business days after delivery of the Offer Notice, to elect to add the Second
Floor Space to the Subleased Premises for a Term commencing on the Second Floor
Delivery Date and ending on the last day of the Term of this Sublease.  In the
event Sublessee serves an Acceptance Notice, Sublessee shall state therein
whether or not Sublessee accepts the Second Floor Terms set forth in
Sublessor's Offer Notice and, if Sublessee does not accept such terms, which of
such Second





                                       10
<PAGE>   11

Floor Terms Sublessee does not accept and, as to each of such unacceptable
terms, an alternative, determined reasonably and in good faith, which would be
acceptable to Sublessee.  In the event Sublessee accepts all of the Second
Floor Terms set forth in Sublessor's Offer Notice,  the Second Floor Space
shall as of the Second Floor Delivery Date, become part of the Subleased
Premises and shall be subject to all the terms and conditions of this Sublease,
except as otherwise provided in the Second Floor Terms.

                 (c)      In the event Sublessee does not accept the Second
Floor Terms, then Sublessor and Sublessee shall, for a period of five business
days after delivery to Sublessor of Sublessee's Acceptance Notice (the
"Negotiation Period"), negotiate with each other in good faith concerning the
Second Floor Terms which were not accepted by Sublessee.  In the event that, at
the end of the Negotiation Period, Sublessor and Sublessee are unable to reach
agreement concerning the Second Floor Terms, Sublessee shall have the right, by
written notice to Sublessor within three business days after the end of the
Negotiation Period (the "Election Notice"), the elect either (i) to withdraw
Sublessee's Acceptance Notice or (ii) to have the Second Floor Terms determined
by binding arbitration, as provided herein.  Failure of Sublessee to deliver
the Election Notice within such three business day period shall be deemed an
election by Sublessee to withdraw Sublessee's Acceptance Notice.  In the event
Sublessee elects, as provided above, to have the Second Floor Terms determined
by binding arbitration, Sublessee's Acceptance Notice shall thereafter be
irrevocable, and the matters upon which Sublessor and Sublessee are unable to
agree shall be referred to an arbitrator selected by Sublessor and Sublessee,
or if Sublessor and Sublessee are unable to agree upon an arbitrator, an
arbitrator appointed by the Chicago, Illinois office of the American
Arbitration Association, whose decision as to such matters shall be final and
binding upon Sublessor and Sublessee.    The arbitrator shall be a person with
at least 10 years' experience in commercial leasing in the Chicago, Illinois
western suburbs.  The fees and expenses of the arbitrator shall be paid by
Sublessor and Sublessee in equal shares.  Upon request by Sublessor, Sublessee
shall execute and deliver to Sublessor an appropriate amendment to this
Sublease, reflecting the addition of the Second Floor Space to the Subleased
Premises on terms established as set forth above in this paragraph.

                 (d)      In the event Sublessee does not deliver an Acceptance
Notice with in the 120 day period provided in subparagraph (a) above, or in the
event Sublessee's Acceptance Notice is withdrawn or deemed withdrawn, Sublessee
shall have no further rights under this paragraph or with respect to the Second
Floor Space, and, thereafter, Sublessor shall be free to sublease the same to
any party upon such terms as Sublessor, in its sole discretion, may accept.

         18.     BUILT-IN OFFICE FURNITURE.        Sublessor agrees to leave in
the Subleased Premises Sublessor's existing built-in cubicle furnishings,
consisting generally of work surface, overhead storage and pedestal
drawer/files.  Sublessee shall have the right, at no cost to Sublessee to use
such furniture during the Term of this Sublease and any extension thereof to
which Sublessor and Sublessee may agree; however, such furniture shall remain
the property of Sublessor.  Sublessee agrees that such furniture may remain
within the Subleased Premises at the time possession of the Subleased Premises
is delivered to Sublessee.

         19.     INSURANCE.

                 (a)      Sublessee shall maintain at its sole expense
throughout the Term the following types of insurance:

                          (i)     comprehensive general public liability
         insurance for bodily injury, death and damage to property of others,
         including tenant's legal liability for damage to the Subleased
         Premises and blanket contractual liability, with respect to all
         business conducted in, at, upon or from the Subleased Premises and the
         use and occupancy thereof including the activities, operations and
         work conducted or performed by Sublessee, by any other person on
         behalf of the Sublessee, by those for whom Sublessee is in law
         responsible and by any other person on the Subleased Premises.  The
         aforesaid policy or policies shall be written with inclusive limits of
         not less than $3,000,000 for any one accident or occurrence or such
         higher limits as the Sublessor shall reasonably require from time to
         time;

                          (ii)    all risk insurance including extended
         coverage endorsement for the risks of water escape and leakage from
         fire protective devices and such additional perils as the Sublessor
         shall reasonably require from time to time in respect of Sublessee's
         fixtures, Sublessee's furnishings, the Sublessee's equipment, and the
         Subleased Premises.  The aforesaid policy or policies shall be written
         with insurance limits of not less than the full replacement cost
         thereof, on a stated amount basis, subject only to such deductibles
         and exclusions as Sublessor may approve; and

                          (iii)   such other insurance as Sublessor may
         reasonably require having regard to the risks which are customarily
         insured against by prudent tenants of similar leased premises.

                 (b)      All policies of physical damage insurance required to
be maintained by Sublessee on property covered under this Paragraph shall be
taken out with insurers reasonably acceptable to the Sublessor, shall be in
form and on terms and conditions satisfactory from time to time to the
Sublessor, shall name as additional insured (i) Sublessor, (ii) the Master
Landlord, and (iii) such other persons as Sublessor may from time to time
designate, and shall be non-contributing with, and shall apply only as primary
and not as excess to, any other insurance available to the Sublessor.

                 (c)      All policies of liability insurance required to be
maintained by Sublessee shall be taken out with insurers reasonably acceptable
to Sublessor and shall be in a form and on terms and conditions reasonably
acceptable to Sublessor and shall include Sublessor as additional insured and
in addition shall contain cross-liability and severability clauses in respect
of claims by Sublessee or other persons or both as if Sublessor was separately
insured.  If both Sublessor and Sublessee have claims to be indemnified under
any such liability insurance, the indemnity shall be first applied to the
settlement of the claim of Sublessor and the balance to the settlement of the
claim of Sublessee.





                                       12
<PAGE>   13


                 (d)      All policies of insurance required to be maintained
by Sublessee shall contain provisions prohibiting the insurer from materially
altering to the detriment of  Sublessor or canceling the coverage or allowing
it to lapse without first giving Sublessor at least 30 days' prior notice
thereof.

                 (e)      Sublessee shall deliver to Sublessor from time to
time copies of current policies or certificates or other proof as may be
required by Sublessor to establish Sublessee's insurance coverage in effect
from time to time and the payment of premiums thereon.  If Sublessee fails to
insure or pay premiums or to deliver satisfactory proof thereof as so required,
Sublessor may but shall not be obliged to obtain such insurance on behalf of
Sublessee and Sublessee shall pay to Sublessor forthwith on demand Sublessor's
cost of obtaining such insurance.

                 (f)      Each of Sublessor and Sublessee hereby waives any and
every claim for recovery from the other for any and all loss or damage to the
Building or Subleased  Premises or to the contents thereof, whether such loss
or damage is due to the negligence of Sublessor or Sublessee or its respective
agents or employees, to the extent that the amount of such loss or damage is
recovered under its policies of insurance; provided, however, that the
foregoing waiver shall not be operative in any case where the effect thereof is
to invalidate any insurance coverage of the waiver party or increase the cost
of such insurance coverage; provided further, however, that Sublessor and
Sublessee each agree to give notice of the terms of this mutual waiver to each
insurance company which has issued, or in the future may issue, policies of
physical damage to it, and to have said insurance policies properly endorsed,
if necessary, to prevent the invalidation of said insurance coverage by reason
of said waiver.

         20.     LIMITATION OF LIABILITIES; INDEMNIFICATION.

                 (a)      Subject to the provisions of paragraph 13(c) hereof,
and excluding any of the following arising out of Sublessor's negligence,
willful misconduct or breach of Sublessor's obligations under this Sublease, no
claim for damages or compensation or abatement of rent or otherwise shall be
made by Sublessee by reason of inconvenience, nuisance or discomfort arising
from the diminution in the quality or quantity or interruption or cessation of
or failure in the supply of any utilities, services or systems serving the
Subleased Premises or from the repair, renovation or rebuilding of any portion
of the Building or basic systems thereof nor shall the same give rise to a
claim in Sublessee's favor that such interruption, cessation, failure, repair,
renovation or rebuilding constitutes actual or constructive, total or partial
eviction from the Subleased Premises.

                 (b)      To the extent not prohibited by law, and excluding
the negligence and willful misconduct of Sublessor, and Sublessor's employees,
agents, servants, contractors, or invitees, Sublessor shall not be liable or in
any way responsible for the death of or injury to Sublessee or others, or for
the loss of or damage to property (including books, records, files, money,
securities, negotiable instruments, papers or other valuables) of Sublessee or
others, or for any indirect or consequential or economic loss, injury or damage
(including business losses or damages for personal discomfort or inconvenience)
of Sublessee or others arising from or out of any occurrence or situation in,
upon, at or relating to the Subleased Premises and/or the Building, and without
limiting the generality of the foregoing, Sublessor shall not be





                                       13
<PAGE>   14

liable or in any way responsible for any death, injury, loss or damage to
persons or property resulting from electricity, water, rain, flood, snow, ice
or leaks from any part of the Subleased Premises or the Building or from the
pipes, sprinklers, appliances, plumbing works, roof, windows or subsurface of
any floor or ceiling of the Building; or caused by other tenants, occupants or
persons in the Subleased Premises or other premises in the Building or the
public; or caused by operations in the construction of any private, public or
quasi-public work; or against which Sublessee is required to insure pursuant to
this Sublease.

                 (c)      Sublessee shall and hereby does indemnify the
Sublessor, its shareholders, directors, officers,  agents and employees,
contractors, licensees or concessionaires, and save it and each of them
harmless from and against any and all claims, actions, damages, liabilities,
loss, costs and expenses, including legal expenses, whatsoever including,
without limitation, those in respect of loss of life, personal injury in, upon
or at the Subleased Premises, the occupancy or use of the Subleased Premises,
signs of Sublessee, or any act or omission of, or work done by or on behalf of,
or breach of this Sublease by, Sublessee, its servants, agents, employees,
contractors, sub-tenants, licensees, concessionaires or other occupants of the
Subleased Premises, or any person for whom Sublessee is responsible at law,
including, without limitation, Sublessee's customers or any person having
business with Sublessee.  This indemnification shall survive the expiration of
the Term by lapse of time or otherwise.

                 (d)      Sublessor shall and hereby does indemnify the
Sublessee, its shareholders, directors, officers,  agents and employees,
contractors, licensees or concessionaires, and save it and each of them
harmless from and against any and all claims, actions, damages, liabilities,
loss, costs and expenses, including legal expenses, whatsoever including,
without limitation, those in respect of loss of life, personal situation in,
upon or at the Subleased Premises, the occupancy or use of the Building by
Sublessor, signs of Sublessor, or any act or omission of, or work done by or on
behalf of, or breach of this Sublease by, Sublessor, its servants, agents,
employees, contractors, sub-tenants, licensees, concessionaires or other
occupants of the Subleased Premises, or any person for whom Sublessor is
responsible at law, including, without limitation, Sublessor's customers or any
person having business with Sublessor.  This indemnification shall survive the
expiration of the Term by lapse of time or otherwise.

         21.     NOTICES.  All notices or demands required or permitted under
this Sublease shall be in writing and shall be addressed as set forth herein
below or to such other address as either party may, by written notice to the

Sublease to be performed or observed by such party.

accordance with the laws of the State of Illinois.

                 (c)      If any term, covenant or condition of this Sublease
or the application thereof to any person or circumstance shall be held to be or
rendered invalid, unenforceable or illegal, then such term, covenant or
condition shall be considered separate and severable from the remainder of this
Sublease, shall not affect, impair or invalidate the remainder of this
Sublease, and shall continue to be applicable to and enforceable to the fullest
extent permitted by law against any person or circumstances other than those as
to which it has been held or rendered invalid, unenforceable or illegal.

agreements, conditions or understandings between the parties hereto concerning
the Subleased Premises and the subject matter of this Sublease.  No alteration,

expressions used in any provision of this Sublease relate to the whole of this
Sublease and not to such provision alone, unless otherwise expressly provided,

construed as including the plural and the masculine, feminine and neuter
respectively where the fact or context so requires.

                 (h)      Time is of the essence of this Sublease and of every
part hereof.

                          (iii)   Sublessor is the owner of the entire Tenant's
         interest under the Master Lease, subject to no claim, lien, charge or

                          (iv)    Sublessor has paid all Base Rent, Rent
         Adjustments and Rent Adjustment Deposits due and owing under the
         Master Lease through October 31, 1996;

                          (v)     Sublessor has received no notice, and has no
         knowledge of, any default by Sublessor under the Master Lease and to
         the knowledge of Sublessor no event has occurred which through the
         passage of time or otherwise would result in a default by Sublessor
         under the Master Leases or, to the knowledge of Sublessor, would
         result in a default by Master Landlord under the Master Lease;

                          (vi)    Except with respect to the consent of Master
         Landlord required under the Master Lease, Sublessor has full right and
         authority to sublet the Subleased Premises to Sublessee and to enter

         As used in this subparagraph 24(j), references to Sublessor's
knowledge and phrases of similar import shall mean and be limited to the actual
knowledge, without investigation, of Michael J. Geisen, Sublessor's Executive
Vice President.

         (k)     The warranties and representations contained in subparagraphs
(j) (i) through (x) above shall be effective as of the Commencement Date and
the Space B Commencement Date as if such representations and warranties were
made on said Commencement Date and Space B Commencement Date.

         (l)     In the event this Sublease, and Sublessee's right of
possession under this Sublease, are terminated by reason of a termination of
the Master Lease (other than a termination of the Master Lease resulting from a
default by Sublessee in its observance or compliance with the terms of the
Master Lease as they apply to the Subleased Premises), all future rental and
other obligations of Sublessee under this Sublease shall terminate, except to
the extent of obligations which expressly survive termination pursuant to the
terms of this Sublease or the Master Lease, to the extent incorporated herein.

follows:
 
1.   TERM.

occupancy on the Commencement Date or in the event Landlord is unable to deliver
possession on such date by reason of the holding over or retention of possession
by any tenant or occupant, this Lease shall nevertheless continue in force and
effect, but Rent (as hereinafter defined) shall abate until the Premises are
ready for occupancy or until the Landlord is able to deliver possession, as the
case may be, and Landlord shall have no other liability whatsoever on account
hereof; provided, however, there shall be no abatement of Rent if the Premises
are not ready for occupancy because of the failure to complete the installation
of special equipment, fixtures or materials ordered by Tenant, or because of any
delays resulting from Tenant's failure to promptly submit plans in accordance
with the Work Letter attached hereto as Exhibit B or resulting from changes or
additions to Tenant's plans after the initial submission thereof if changes
during construction do, in fact, cause a delay or impede construction. The
Premises shall not be deemed incomplete or not ready for occupancy if only
insubstantial details of construction, decoration or mechanical adjustments
remain to be done. The determination of Landlord's architect or interior space
planner for the Building shall be final or conclusive on Tenant as to whether
the Premises are completed and ready for occupancy, subject to punchlists or

prior to the Commencement Date; all of the covenants and conditions of this
Lease shall be binding upon the parties hereto with respect to such whole or
part of the Premises as if the Commencement Date had been fixed as the date when
Tenant took possession of such whole or part of the Premises.

described in this Paragraph 2 be deemed to accelerate or defer the Termination
Date.

right, immediately after execution of this Lease by both Landlord and Tenant,
and prior to the Commencement Date, to take possession of its Initial Computer
Space. Landlord also agrees to commence demolition in the Initial Office Space
upon execution of this Lease by Landlord and Tenant and to use its best efforts
to complete

construction in said area by July 15, 1987, as extended by any delay caused by
Tenant. If Landlord fails to complete the required demolition and reconstruction
by that date, Landlord agrees to pay Tenant the sum of $10,000.00 as penalty
therefor. Landlord will continue said construction to its completion, in any
case.
 
     Rent shall not be payable or owed by Tenant for areas so occupied, but

Calendar Year on an accrual basis) paid or incurred by Landlord or Landlord's
beneficiaries in connection with the ownership, management, operation and repair
of the Land and Building, except the following:
 
     (I) Costs of alterations of any tenant's premises;
 
     (II) Principal or interest payments on loans secured by mortgages or trust

after the Base Year which reduces any component cost included within Operating
Expenses; and (b) the cost of any capital improvements which are necessary to

     (IV) Real estate brokers' leasing commissions.

     B.  EXPENSE ADJUSTMENT.  Tenant shall pay to Landlord as Rent, in addition
to the Base Rent required by Section 3 hereof, an amount to Tenant's
Proportionate Share of the total of Taxes paid during each Calendar Year and
Operating Expenses incurred with respect to each Calendar Year said amounts
shall be paid in-monthly installments, in an amount estimated from time to time
by Landlord but not to exceed twice per Calendar Year, and communicated by
written notice to Tenant. Landlord shall cause to be kept books and records
showing Operating Expenses and Taxes in accordance with an appropriate system of
accounts and
 
                                        4
<PAGE>   26
 
accounting practices consistently maintained. As promptly as practicable
following the close of each Calendar Year. Landlord shall cause a firm of
independent public accountants to review such books and records (and to do such
other work as may be necessary to enable such firm to give the certificate
hereinafter required) and to deliver to Landlord its certificate specifying the
amount of Operating Expenses and Taxes for such Calendar Year for the Building.
After receipt of such certificate, Landlord shall cause the amount of the total
of taxes and operating expenses for such calendar year to be computed based on
Operating Expenses and Taxes for such Calendar Year for the Building as
specified in such firm's certificate and Landlord shall deliver to Tenant a
statement of such amount and Tenant shall pay any deficiency to Landlord as
shown by such statement within thirty (30) days after receipt of such statement.
The certificate of such independent accounting firm as to the amount of
Operating Expenses and Taxes for such Calendar Year for the Building shall
constitute a determination which is final and conclusive on Tenant. If the total
of the estimated monthly installments paid by Tenant during any Calendar Year
exceeds the actual Expenses Adjustment Amount due from Tenant for such Calendar
Year, at Landlord's option, such excess shall be either credited against
payments next due hereunder or refunded by Landlord, provided Tenant is not then
in default hereunder. The amount of any refund of Taxes received by Landlord
shall be credited against Taxes for the year in which such refund is received.
In determining the amount of Taxes for any year, the amount of special
assessments to be included shall be limited to the amount of the installment
(plus any interest payable thereon) of such special assessment required to be
paid during such year if the Landlord had elected to have such special
assessment paid over the maximum period of time permitted by law. All references
to Taxes "for" a particular year shall be deemed to refer to Taxes paid during
such year without regard to when such Taxes are assessed or levied.
Notwithstanding the contents of the above paragraph, Tenant shall have the right
to pay its Expenses Adjustment Amount under protest and cause an audit of
Landlord's books and records to be conducted by Tenant's certified public
accountant at its own expenses. If the result of that audit shows a variance
exceeding 3% from the results of Landlord's certificate, Landlord shall pay the
reasonable cost of Tenant's audit and refund Tenant's share of the variance,
together with interest at the then-current prime rate as published and utilized
by First National Bank, Chicago, plus two (2) per cent.
 
5.   USE OF PREMISES.
 
     Tenant shall continuously and without interruption use and occupy the
entire Premises as an office for the following type of business: and for no
other purpose: executive and general offices and all legal uses incidental
thereto, which may include computer operations.
 
     Landlord acknowledges and agrees that Tenant is in the data processing
business and that nothing herein or in the Rules and Regulations, now or during
the Lease Term, shall interfere with or impede Tenant's use of the Premises for
that purpose.
 
6.   CONDITIONS OF PREMISES.
 
     Subject to a punchlist and to latent defects, the Tenant's taking
possession of any portion of the Premises shall be conclusive evidence that such
portion of the Premises was in good order and satisfactory condition when the
Tenant took possession, except as to latent defects, excluding items of damage
caused by Tenant or its agents, independent contractors or suppliers. No promise
of the Landlord to alter, remodel or improve the Premises or the Building and no
representation by Landlord or its agents respecting the condition of the
Premises or the Building have been made to Tenant or relied upon by Tenant other
than as may be contained in this Lease or in any written amendment hereto signed
by Landlord and Tenant. Landlord agrees to extend to Tenant any manufacturer's
warranties it has relative to the equipment or installation contained in the
Premises.

     Landlord and Tenant agree to cooperate to determine the most cost-effective
method to provide Tenant with its HVAC requirements. After and before the hours
stated in Section 7.A.(i), Landlord agrees to provide Tenant with heat, as
required, on the second floor of the Building, at Landlord's cost plus 5%;
Tenant may alternatively engage its own engineer to determine a more
cost-effective method of obtaining heat.
 
     Landlord's specifications for providing air conditioning are contained in
Exhibit F to Lease.
 
     (ii) Adequate electrical wiring and facilities for standard building
lighting fixtures provided by Landlord and for Tenant's incidental uses. Tenant
shall bear the cost of replacement of bulbs and ballasts for lighting fixtures.
In respect of such incidental uses, adequate electrical wiring and facilities
will be furnished in the Premises by Landlord, provided that (a) the connected
electrical load of the incidental use equipment does not exceed an average of
one watt per square foot of the Premises; (b) the electricity so furnished for
incidental uses will be at a nominal 120 volts and no electrical circuit for the
supply of such incidental use will have a current capacity exceeding 15 amperes;
and (c) such electricity will be used only for equipment and accessories normal
to office usage. If Tenant's requirements for electricity for incidental uses
are in excess of those set forth in the preceding sentence, the Landlord
reserves the right to require Tenant to install the conduit wiring and other
equipment necessary to supply electricity for such excess incidental use
requirements at the Tenant's expense by arrangement with Commonwealth Edison
Company or another approved local utility.
 
     (iii) Village water from the regular Building outlets for drinking,
lavatory and toilet purposes.
 
     (iv) Janitor services at Tenant's request; Monday through Friday in and
about the Premises, comparable to the standard janitor service furnished by
other first-class office buildings, unless Tenant contracts directly for such
services on prior reasonable notice to Landlord.
 
     (v) Window washing of all inside and outside windows in the Premises at
intervals to be determined by Landlord, but in no event fewer than three (3)
times per year.
 
     (vi) Adequate operatorless passenger and freight elevator service at all
times.
 
     B.  BILLING FOR ELECTRICITY.
 
     1.  SEPARATE METERING. Tenant shall pay for the use of all electrical
service to the Premises (other than the electrical service necessary for
Landlord to fulfill its obligation to provide heating and air conditioning as
provided in Paragraph 7A(i) hereof). Provided that Landlord can make
arrangements satisfactory to Landlord and Tenant with the utility company
supplying electricity to the Premises, Tenant shall be billed directly by such
utility and Tenant agrees to pay each bill promptly in accordance with its
terms. In the event that for any reason Tenant cannot be billed directly,
Landlord shall forward each bill with respect to the Premises and Tenant shall
pay it promptly in accordance with its terms.
 
     2.  LACK OF SEPARATE METERING. If Tenant cannot be separately metered for
any reason, Tenant shall pay Landlord as additional Rent, in monthly
installments at the time prescribed for monthly installments of Rent, an annual
amount, as estimated by Landlord from time to time, which Tenant would pay for
such electricity if the same were separately metered to the Premises by the
local electric utility company and billed to Tenant at such utility company's
current rates.
 
     3.  ALLOCATION OF ELECTRICITY IN INITIAL COMPUTER SPACE. Landlord agrees to
cause to be installed a separate circuit and electric meter, for Computer
Sciences Corporation's computer area, so that upon completion of said work (1)
electric usage in Tenant's Initial Computer Space will be accurately measured
 
                                        6
<PAGE>   28
 
and (2) Tenant will pay thereafter only for electricity metered and used in its
own Initial Computer Space. The cost of the separate circuit and meter and their
installation shall be allocated as between Landlord and Tenant as found in
Section A-8. of the Addendum. Nothing contained in this Section 7.B.3. shall
relieve Tenant from the obligation to pay for its electric usage in the Initial
Office Space or in spaces later leased from Landlord.
 
     Tenant agrees that Landlord shall not be liable in damages, by abatement of
Rent or otherwise, for failure to furnish or delay in furnishing any service, or
for any diminution in the quality or quantity thereof, when such failure or
delay or diminution is occasioned, in whose or in part, by repairs, renewals or
improvements, by any strike, lockout or other labor trouble, by inability to
secure electricity, gas, water, or other fuel at the Building after reasonable
effort so to do, by any accident or casualty whatsoever, by the act or default
of Tenant or other parties, or by any other cause beyond Landlord's reasonable
control; and such failures or delays or diminution shall never be deemed to
constitute an eviction or disturbance of the Tenant's use and possession of the
Premises or relieve the Tenant from paying Rent or performing any of its
obligations under this Lease. Landlord shall be diligent in its efforts to cure
such failure or delay or diminution.
 
     Notwithstanding the contents of Section 7.C., Rent shall abate if heat is
not provided to the Premises of five (5) successive days (beginning on the sixth
day and only until heat is restored). A similar formula shall be applicable if a
water pipe or cooling tower bursts, causing substantial disruption to Tenant's
business, and is not cured and repaired within five (5) days.
 
     Notwithstanding the contents of Section 7.C., if Landlord's negligence is
the cause of the interruption of the providing of electricity to Tenant,
Tenant's Rent shall abate if electricity is not restored within five (5) days;
this covenant shall not be subject to interruption of electricity, due to force
majeure. If the electricity fails through no fault of Landlord, and the UPS is
activated and then fails, Tenant's Rent shall not abate so long as the original
interruption of electricity was not due to Landlord's negligence. Landlord will
provide Tenant with UPS "spares" in the Premises and in the Building; Tenant
shall have the responsibility to maintain the UPS and to recharge them, as
necessary.
 
     Notwithstanding the contents of Section 7.C., in any case of interruption
of services, Tenant shall have the right to self-help and to offset against Rent
the reasonable cost of that self-help.
 
     D.  CHARGES FOR SERVICES.
 
     Charges for any services for which Tenant is required to pay from time to
time hereunder including but not limited to hoisting services (except that there
shall be no charge for hoisting services related to Tenant's initial move-in),
or after hours heating or air conditioning shall be due and payable at the same
time as the installment of Rent with which they are billed, or, if billed
separately, shall be due and payable within ten (10) days after such billing. If
Tenant shall fail to make payment for any such services, Landlord may, with
notice to Tenant, discontinue any or all of such services and such
discontinuance shall not be deemed to constitute an eviction or disturbance of
the Tenant's use and possession of the Premises or relieve Tenant from paying
Rent or performing any of its other obligations under this Lease.
 
8.   REPAIRS.
 
     Tenant will, at Tenant's own expense, keep the Premises (except for damage
caused by the negligence of Landlord, its employees, agents, contractors or
invitees), in good order, repair and condition at all times during the Term, and
Tenant shall promptly and adequately repair all damage to the Premises and
replace or repair all damaged or broken fixtures and appurtenances, under the
supervision and subject to the approval of the Landlord, and within any
reasonable period of time specified by the Landlord. If the Tenant does not do
so, Landlord may, but need not, make such repairs and replacements, and Tenant
shall pay Landlord the reasonable cost thereof, including a percentage of the
cost thereof (to be uniformly established for the Building) sufficient to
reimburse Landlord (at a cost not to exceed 10% of the repairs and replacements)
for all overhead, general conditions, fees and other costs or expenses arising
from Landlord's involvement with such repairs and replacements forthwith upon
being billed for same. Landlord may, but shall not be required to, enter the
Premises at all reasonable times to make such repairs, alterations, improvements
and additions to the Premises or to the Building or to any equipment located in
the Building as Landlord shall desire or deem necessary or as Landlord may be
required to do by governmental authority or court order or decree.
 
                                        7
<PAGE>   29
 
Notwithstanding the contents of this Section, Landlord shall be solely
responsible for repairs associated with the Building's structural and
weight-bearing components and glass, unless damage to said items are caused by
Tenant's negligence. Landlord agrees to provide reasonable notice of repairs it
is conducting and to attempt to minimize the disturbance to Tenant's business
resulting thereby.
 
9.   ADDITIONS AND ALTERATIONS.
 
     Tenant shall not, without the prior written consent not to be unreasonably
withheld or delayed, of Landlord, make any alterations, improvements or
additions to the Premises. Landlord's refusal to give said consent shall be
conclusive. If Landlord consents to said alterations, improvements or additions,
it may impose such conditions with respect thereto as Landlord deems
appropriate, including, without limitation, requiring Tenant to furnish Landlord
with security for the payment of all costs to be incurred in connection with
such work, insurance against liabilities which may arise out of such work, and
plans and specifications plus permits necessary for such work. The work
necessary to make any alterations, improvements or additions to the Premises
shall be done at Tenant's expense by employees of or contractors hired by
Landlord except to the extent Landlord gives its prior written consent not to be
unreasonably withheld or delayed, to Tenant's hiring contractors. Tenant shall
promptly pay to Landlord or to Tenant's contractors, as the case may be, when
due, the cost of all such work and of all decorating required by reason thereof.
Tenant shall also pay to Landlord a percentage of the cost of such work (such
percentage not to exceed 10%) sufficient to reimburse Landlord for all overhead,
general conditions, fees and other costs and expenses arising from Landlord's
involvement with such work. Upon completion of such work Tenant shall deliver to
Landlord, if payment is made directly to contractors, evidence of payment,
contractors' affidavits and full and final waivers of all liens for labor,
services or materials. Tenant shall defend and hold Landlord and the Land and
Building harmless from all costs, damages, liens (unless Landlord is acting as
the general contractor) and expenses related to such work. All work done by
Tenant or its contractors pursuant to Sections 8 or 9 shall be done in a
first-class workmanlike manner using only good grades of materials and shall
comply with all insurance requirements and all applicable laws and ordinances
and rules and regulations of governmental departments or agencies.
 
     All alterations, improvements and additions to the Premises, whether
temporary or permanent in character, made or paid for by Landlord or Tenant,
shall without compensation to Tenant become Landlord's property at the
termination of this Lease by lapse of time or otherwise and shall, be
relinquished to Landlord in good condition, ordinary wear excepted.
 
10. COVENANT AGAINST LIENS.
 
     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 be placed upon Landlord's title or interest in the
Land, Building or Premises, and any and all liens and encumbrances created by
Tenant shall attach to Tenant's interest only. Tenant covenants and agrees not
to suffer or permit any lien of mechanics or materialmen or others to be placed
against the Land, Building or the Premises with respect to work or services
claimed to have been performed for or materials claimed to have been furnished
to Tenant or the Premises, and, in case of any such lien attaching, Tenant
covenants and agrees to cause it to be immediately released and removed of
record.
 
     In the event that such lien is not immediately released and removed,
Landlord, at its sole option, may take all action necessary to release and
remove such lien (without any duty to investigate the validity thereof) and
Tenant shall promptly upon notice reimburse Landlord for all sums, costs and
expenses (including reasonable attorneys' fees) incurred by Landlord in
connection with such lien. Notwithstanding the contents of the preceding
paragraph, Landlord shall give Tenant notice of any such lien and Tenant shall
have the right to bond over it in a reasonable period of time with a bond
reasonably satisfactory to Landlord.
 
11. INSURANCE.
 
     A.  WAIVER OF SUBROGATION.
 
     Landlord and Tenant each hereby waive any and every claim for recovery from
the other for any and all loss of or damage to the Building or Premises or to
the contents thereof, which loss or damage is covered by valid and collectible
fire and extended coverage insurance policies, to the extent that such loss or
damage is
 
                                        8
<PAGE>   30
 
recoverable under said insurance policies. Inasmuch as this mutual waiver will
preclude the assignment of any such claim by subrogation (or otherwise) to an
insurance company (or any other person), Landlord and Tenant each agree to give
to each insurance company which has issued, or in the future may issue, to it
policies of fire and extended coverage insurance, written notice of the terms of
this mutual waiver, and to have said insurance policies properly endorsed, if
necessary, to prevent the invalidation of said insurance coverage by reason of
said waiver. Landlord shall carry insurance providing full replacement coverage
of the Building at all times during this Lease and liability insurance for
common areas of the Building in limits of not less than $1,000,000 and with a
deductible under said policy or policies not greater than the deductible for
similar quality buildings in the OakBrook Market.
 
     B.  COVERAGE.
 
     Tenant shall carry insurance during the entire Term insuring Tenant and
Landlord as their interests may appear with terms, coverages and in companies
satisfactory to Landlord, and with such reasonable increases in limits as
Landlord may from time to time request, but initially Tenant shall maintain the
following coverages in the following amounts;
 
     (i) in case of personal injury to or death of any person or persons, not
less than $1,000,000 for each injury or death to a person and $3,000,000 for
each incident involving personal injury or death to persons, and, in case of
property damage, not less than $1,000,000 for any one occurrence; and
 
     (ii) in case of fire, sprinkler leakage, malicious mischief, vandalism, and
other extended coverage perils, for the full insurance replacement value of all
additions, improvements and alterations to the Premises which are beyond the
"building standard" Tenant improvements provided by Landlord and of all office
furniture, trade fixtures, office equipment, merchandise and all other items of
Tenant's property on the Premises.
 
     Tenant shall, prior to the commencement of the Term, furnish to Landlord
certificates evidencing such coverage, which certificates shall state that such
insurance coverage may not be changed or cancelled without at least ten days
prior written notice to Landlord and Tenant.
 
     C.  AVOID ACTION INCREASING RATES.
 
     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, directly or indirectly, make any use of the Premises which may
thereby be prohibited or be dangerous to person or property or which may
jeopardize any insurance coverage, or may increase the cost of insurance or
require additional insurance coverage. If by reason of the failure of Tenant to
comply with the provisions of this Section 11C, any insurance coverage is
jeopardized or insurance premiums are increased, Landlord shall have the option
to require Tenant to make immediate payment of the increased insurance premium.
 
12. FIRE OR CASUALTY.
 
     Paragraph 8 hereof notwithstanding, if the Premises or the Building
(including machinery or equipment used in its operation) shall be damaged by
fire or other casualty and if such damage does not render all or a substantial
portion of the Premises or Building untenantable, then Landlord shall repair and
restore the same with reasonable promptness, subject to reasonable delays for
insurance adjustments and delays caused by matters beyond Landlord's reasonable
control. If any such damage renders all or a substantial portion of the Premises
or Building untenantable, Landlord shall have the right to terminate this Lease
as of the date of such damage (with appropriate prorations of Rent being made
for Tenant's possession subsequent to the date of such damage of those
tenantable portions of the Premises) upon giving written notice to the Tenant at
any time within sixty (60) days after the date of such damage. If any such
damage renders all or more than fifty percent (50%) of the Premises untenantable
Tenant shall also have the right to terminate this Lease as of the date of such
damage upon giving written notice to Landlord at any time within forty-five (45)
days after the date of such damage. Unless this Lease is terminated as provided
in the two preceding sentences and Landlord shall proceed with reasonable
promptness to repair and restore the Premises, subject to reasonable delays for
insurancee adjustments and delays caused by matters beyond Landlord's reasonable
control. Rent, however shall abate on those portions of the Premises as are,
from time to time, untenantable as a result of such damage.
 
                                        9
<PAGE>   31
 
     Notwithstanding the contents of this paragraph, Landlord shall use its best
efforts and diligence to rebuild the Premises after any fire or casualty; if the
Building is damaged by fire or other casualty and Landlord chooses not to
rebuild, Landlord shall provide Tenant notice within 30 days of said fire or
casualty of Landlord's decision; if Landlord chooses to rebuild, it shall use
its best efforts and diligence to complete the restoration as quickly as
possible.
 
     If said restoration is not completed within 180 days from date of
inception, Tenant shall have the right to terminate this Lease and all
obligations hereunder.
 
     Tenant hereby acknowledges that Landlord is under no obligation to insure
Landlord's interest in the Premises or the Building, except as provided herein.
 
     Notwithstanding anything to the contrary herein set forth, Landlord shall
have no duty pursuant to this Section 12 to repair or restore any portion of the
alterations, additions or improvements in the Premises or the decoration thereto
except to the extent that such alterations, additions, improvements and
decoration were provided by Landlord, at Landlord's cost, at the beginning of
the Term. If Tenant wants any other or additional repairs or restoration and if
Landlord consents thereto, the same shall be done at Tenant's expense subject to
all of the provisions of Section 8 hereof.
 
13. WAIVER OF CLAIMS -- INDEMNIFICATION.
 
     To the extent not prohibited by law, and excluding the negligence of
Landlord, its employees, agents, servants, contractors, or invitees, Landlord
and its officers, agents, servants and employees shall not be liable for any
damage either to person or property or resulting from the loss of use thereof
sustained by Tenant or by other persons due to the Building or any part thereof
or any appurtenances thereof becoming out of repair, or due to the happening or
any accident or event in or about the Building, or due to any act or neglect of
any tenant or occupant of the Building or of any other person. This provision
shall apply particularly (but not exclusively) to damage caused by gas,
electricity, snow, frost, steam, sewage, sewer gas or odors, fire, water or by
the bursting or leaking of pipes, faucets, sprinklers, plumbing fixtures, and
windows, 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 causes specifically enumerated above or to some other cause of an entirely
different kind. Tenant further agrees that all personal property upon the
Premises, or upon-loading docks, receiving and holding areas, or freight
elevators of the Building, shall be at the risk of Tenant only, and that
Landlord shall not be liable for any loss or damage thereto or theft thereof.
Without limitation of any other provisions thereof, Tenant agrees to defend,
protect, indemnify and save harmless Landlord from and against all liability to
third parties arising out of the acts of Tenant and its servants, agents,
employees, contractors, suppliers, workmen and invitees. This Section shall be
reciprocal in effect between Landlord and Tenant, and Landlord except the
trustee agrees to defend, protect, indemnify and save harmless Tenant from and
against all liability to third parties arising out of the acts of Landlord and
its servants, agents, employees, contractors, suppliers, workmen and invitees.
 
14. NONWAIVER.
 
     No waiver of any provision of this Lease shall be implied by any failure of
Landlord to enforce any remedy on account of the violation of such provision,
even if such violation be continued or repeated subsequently, and no express
waiver shall affect any provision other than the one specified in such waiver
and that one only for the time and in the manner specifically stated. No receipt
of moneys by Landlord from Tenant after the termination of this Lease shall in
any way alter the length 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 Tenant prior to the receipt of such moneys,
it being 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 Rent due, and the payment of said Rent shall not waive or affect
said notice, suit or judgment.
 
15. CONDEMNATION.
 
     If the Land or the Building or any portion thereof shall be taken or
condemned by any competent authority for any public or quasi-public use or
purpose (a "taking"), or if the configuration of any street, alley, riverbank,
or bridge adjacent to the Building is changed by any competent authority and
such taking or change
 
                                       10
<PAGE>   32
 
in configuration makes it necessary to remodel or reconstruct the Building.
Landlord shall have the right, exercisable at its sole discretion, to cancel
this Lease upon not less than ninety (90) days notice prior to the date of
cancellation designated in the notice. No money or other consideration shall be
payable by Landlord to Tenant for the right of cancellation and Tenant shall
have no right to share in the condemnation award or in any judgment for damages
caused by such taking or change in configuration. Tenant, however, shall have
the right to seek its own separate award in any such proceeding and for
improvements installed and paid for by it, so long as any such award does not
otherwise diminish Landlord's award.
 
16. ASSIGNMENT AND SUBLETTING.
 
     a. Tenant shall not, without Landlord's prior written consent;
 
     (i) assign, hypothecate, mortgage, encumber, or convey this Lease;
 
     (ii) allow any transfer thereof or any lien upon Tenant's interest by
operation of law;
 
     (iii) sublet the premises or any part thereof; or
 
     (iv) permit the use or occupancy of the premises or any part thereof by
anyone other than Tenant.
 
     b. If Tenant desires the consent of Landlord to an assignment of the entire
demised premises for the remaining term or subletting of all or a part of the
demised premises (the entire demised premises for the remaining term if an
assignment is desired or the portion of the demised premises if a sublet is
desired being hereinafter referred to as "Subject Premises"), Tenant shall
submit to Landlord;
 
     (i) the proposed sublease or assignment (executed by Tenant and subtenant
or assignee), which is not to commence prior to the first day of the month
immediately following the month in which the thirtieth day following the
submission to Landlord occurs, and
 
     (ii) sufficient information to permit Landlord to determine the
acceptability of the financial responsibility and character of subtenant or
assignee.
 
     c. Landlord shall not unreasonably withhold its consent except that such
consent need not be granted if:
 
     (i) in the reasonable judgment of Landlord the subtenant or assignee is of
a character or engaged in a business which is not in keeping with the standards
of Landlord for the Building;
 
     (ii) in the reasonable judgment of Landlord the purposes for which the
subtenant or assignee intends to use the Subject Premises are not in keeping
with the standards of Landlord for the Building, it being understood that the
purposes for which subtenant or assignee intends to use the Subject Premises may
not be in violation of this Lease;
 
     (iii) a subletting will result in there being more than two occupants per
floor within the demised premises, including Tenant and all subtenants;
 
     (iv) the Subject Premises is not regular in shape with appropriate means of
ingress and egress and suitable for normal renting purposes;
 
     (v) the subtenant or assignee is either a government (or subdivision or
agency thereof) or an occupant of the Building;
 
     (vi) an assignment is desired and the Subject Premises are less than the
entire demised premises or less than the remaining term is being assigned;
 
     (vii) Tenant is in default under this Lease.
 
     (viii) Tenant has exercised its option to expand or renew under paragraphs
28 or 29.
 
     d. If Landlord grants consent:
 
     (i) the terms and conditions of this Lease, including among other things.
Tenant's liability for the Subject Premises shall in no way be deemed modified,
abrogated or amended;
 
     (ii) Tenant shall pay Landlord $250.00 for each sublease or assignment
submitted as reimbursement to Landlord for expenses incurred, plus 50% of all
net profit ("net profit" being defined hereunder as gross profit less all costs
incurred or concessions granted, including but not limited to rent abatement,
alterations to
 
                                       11
<PAGE>   33
 
Premises, commissions, and attorney fees. The dollar total of said costs and
concessions shall be fully amortized over the term of said sublease of
assignment, and "net profit" calculated after allowing for said amortization)
derived by Tenant in such sublease or assignment.
 
     (iii) the consent shall not be deemed a consent to any further subletting
or assignments by either Tenant, subtenants or assignees.
 
     e. Notwithstanding the contents of this Section, no notice need be given by
Tenant, nor consent obtained by Landlord, as to an assignment of the Lease to an
affiliate of Tenant, so long as guarantor herein (or its successor, guarantor,
possessing a net worth as much as, or greater than, guarantor herein) remains as
guarantor of the Lease. The same shall apply to a merger of Tenant with another
entity, so long as the guarantor herein shall continue as guarantor after such a
merger:
 
17. SURRENDER OF POSSESSION.
 
     Upon the expiration of the Term or upon the termination of Tenant's right
of possession, whether by lapse of time or at the option of Landlord as herein
provided. Tenant shall forthwith surrender the Premises to Landlord in good
order, repair and condition, ordinary wear excepted, and shall, if Landlord so
requires, restore the Premises to the condition existing at the beginning of the
Term. Any interest of Tenant in the alterations, improvements, and additions to
the Premises (including without limitation all carpeting or floorcovering) made
or paid for by Landlord or Tenant shall without compensation to Tenant become
Landlord's property at the termination of this Lease by lapse of time or
otherwise and such alterations, improvements and additions shall be relinquished
to Landlord in good condition, ordinary wear excepted. At the termination of the
Term or of Tenant's right of possession Tenant agrees to remove the following
items of Tenant's property: office furniture, trade fixtures, office equipment
and all other items of Tenant's property on the Premises. Tenant shall pay to
Landlord upon demand the cost of repairing any damage to the Premises and to the
Building caused by any such removal. If Tenant shall fail or refuse to remove
any such property from the Premises, Tenant shall be conclusively presumed to
have abandoned the same, and title thereto shall thereupon pass to Landlord
without any cost either by set-off, credit, allowance or otherwise, and Landlord
may at its option accept the title to such property or at Tenant's expense may
(i) remove the same or any part in any manner that Landlord shall choose,
repairing any damage to the Premises caused by such removal, and (ii) store,
destroy or otherwise dispose of the same without incurring liability to Tenant
or any other person.
 
18. HOLDING OVER.
 
     Tenant shall pay to Landlord an amount as Base Rent equal to 200% of the
Rent herein provided during each month or portion thereof for which Tenant shall
retain possession of the Premises or any part thereof after the termination of
the Term or of Tenant's right of possession, whether by lapse of time or
otherwise, and also shall pay all damages sustained by Landlord, whether direct
or consequential, on account thereof. The provisions of this Section 18 shall
not be deemed to limit or constitute a waiver of any other rights or remedies of
Landlord provided herein or at law.
 
19. ESTOPPEL CERTIFICATE.
 
     The Tenant agrees that, from time to time upon not less than ten days prior
request by Landlord, the Tenant, or Tenant's duly authorized representative
having knowledge of the following facts, will deliver to Landlord a statement in
writing certifying (i) that this Lease is unmodified and in full force and
effect (or if there have been modifications that the Lease as modified is in
full force and effect); (ii) the dates to which Rent and other charges have been
paid; (iii) that the Landlord is not in default under any provision of this
Lease, or, if in default, the nature thereof in detail; and (iv) such further
matters as are set forth on the form of estoppel certificate attached hereto as
Exhibit C and made a part hereof, it being intended that any such statement may
be relied upon by any prospective purchaser or tenant of the Building, any
mortgagees or prospective mortgagees thereof, or any prospective assignee of any
mortgage thereof. Tenant shall execute and deliver whatever instruments may be
required for such purposes, and in the event Tenant fails so to do within twenty
(20) days after demand in writing. Tenant shall be considered in default under
this Lease.
 
                                       12
<PAGE>   34
 
                      STANDARD MORTGAGEE PROTECTION CLAUSE
 
     Tenant agrees to give any Mortgagees and/or Trust Deed Holders, by
Registered Mail, a copy of any Notice of Default served upon the Landlord,
provided that prior to such notice tenant has been notified, in writing, (by way
of Notice of Assignment of Rents and Leases, or otherwise) of the address of
such Mortgagees and/or Trust Deed Holders. Tenant further agrees that if
Landlord shall have failed to cure such default within the time provided for in
this Lease, then the Mortgagees and/or Trust Deed Holders shall have an
additional thirty (30) days within which to cure such default or if such default
cannot be cured within that time, then such additional time as may be necessary
if within such thirty (30) days, any Mortgagee and/or Trust Deed Holder has
commenced and is diligently pursuing the remedies necessary to cure such
default, (including but not limited to commencement of foreclosure proceedings,
if necessary to effect such cure) in which event this Lease shall not be
terminated while such remedies are being so diligently pursued.
 
20. SUBORDINATION.
 
     This Lease is subject and subordinate to all present and future ground or
underlying leases of the Land and to the lien of any mortgages or trust deeds,
now and hereafter in force against the Land and Building, or either, and to all
renewals, extensions, modifications, consolidations and replacements thereof,
and to all advances made or hereafter to be made upon the security of such
mortgages or trust deeds, unless the holders of such mortgages or trust deeds,
or the lessors under such ground lease or underlying leases require in writing
that this Lease shall be superior thereto. Tenant shall at Landlord's request
execute such further instruments or assurances as Landlord may reasonably deem
necessary to evidence or confirm the subordination or superiority of this Lease
to any such mortgages, trust deeds, ground leases or underlying leases. Tenant
hereby irrevocably authorizes Landlord to execute and deliver in the name of
Tenant any such instrument or instruments if Tenant fails to do so, provided
that such shall in no way relieve Tenant from the obligation of executing such
instruments of subordination or superiority.
 
     Tenant agrees to subordinate this Lease to future mortgagee(s) only if
Landlord provides Tenant with a non-disturbance and attornment agreement from
said mortgagee(s). Landlord agrees to submit this Lease, upon its completion,
but prior to execution, to the present mortgagee and to use its best efforts to
obtain from the mortgagee a non-disturbance and attornment agreement in favor of
Tenant. In the event Landlord is unable to obtain said agreement by July 10,
1987, Landlord agrees to provide Tenant, and Tenant agrees to accept from
Landlord an agreement (in form and substance acceptable to Tenant), whereby
LaSalle National Bank and Trust Company, not personally, but U/T/A #107194, 815
Commerce Drive REIP, and The Great-West Life Assurance Company of Winnipeg,
Canada, agree not to sell, convey, or transfer the Building, the real estate
upon which it is situated, the beneficial interest in said land trust, or any
portion thereof, the general partnership interest in the 815 Commerce Drive
REIP, or any portion of their interest or equity therein, prior to the time when
the present mortgage loan encumbering the Building is first due.

any kind to Tenant or any other person, have any one or more of the following
described remedies in addition to all other rights and remedies provided at law
or in equity or elsewhere herein.
 
          (i) Landlord may terminate this Lease and the Term created hereby, in
     which event Landlord may forthwith repossess the Premises and be entitled
     to recover forthwith, in addition to any other sums or damages for which
     Tenant may be liable to Landlord, as damages a sum of money equal to the
     excess of the value of the Base Rent provided to be paid by Tenant for the
     balance of the Term over the fair market rental value of the Premises,
     after deduction of all anticipated expenses of reletting, for said period.
     Should the fair market rental value of the Premises, after deduction of all
     anticipated expenses of reletting, for the balance of the Term exceed the
     value of the Base Rent provided to be paid by Tenant for the balance of the
     Term, Landlord shall have no obligation to pay to Tenant the excess or any
     part thereof or to credit such excess or any part thereof against any other
     sums or damages for which Tenant may be liable to Landlord. Any liquidated
     damages paid to Landlord by operation of this subsection (insofar as said
     damages are attributable to Rent for the balance of the Term) shall be
     discounted to the date of payment at a discount factor equal to 120% of the
     borrowing costs to the U.S. government for a term equal to the term
     commencing with the date of the payment and ending at the Termination Date
     of the Initial Term of the Lease.
 
          (ii) Landlord may terminate Tenant's right of possession and may
     repossess the Premises by forcible entry and detainer suit, by taking
     peaceful possession or otherwise, without terminating this Lease, in which
     event Landlord may, but shall be under no obligation to, relet the same for
     the account of Tenant, for such rent and upon such terms as shall be
     satisfactory to Landlord. For the purpose of such reletting. Landlord is
     authorized to decorate, repair, remodel or alter the Premises. If Landlord
     shall fail to relet the Premises. Tenant shall pay to Landlord as damages a
     sum equal to the amount of the Rent reserved in this Lease for the balance
     of the Term. If the Premises are relet and a sufficient sum shall not be
     realized from such reletting after paying all of the costs and expenses of
     all decoration, repairs, remodeling, alterations and additions and the
     expenses of such reletting and of the collection of the rent accruing
     therefrom to satisfy the Rent provided for in this Lease. Tenant shall
     satisfy and pay the same upon demand therefor from time to time. Tenant
     agrees that Landlord may file suit to recover any sums failing due under
     the terms of this Section 23 from time to time and that no suit or recovery
     of any portion due Landlord hereunder shall be any defense to any
     subsequent action brought for any amount
 
                                       15
<PAGE>   37

prevailing party's fault to become involved or concerned.
 
25.  COVENANT OF QUIET ENJOYMENT.
 
     The Landlord covenants that the Tenant, on paying the Rent, charges for
services and other payments herein reserved and on keeping, observing and

to as "Collateral"), as security for the prompt, full and faithful performance
by Tenant of each and every provision of this Lease and of all obligations of
Tenant hereunder.
 
     (a) If Tenant fails to perform any of its obligations hereunder, Landlord
may use, apply or retain the whole or any part of the Collateral for the payment
of (i) any Rent or other sums of money which Tenant may not have paid when due,
(ii) any sum expended by Landlord on Tenant's behalf in accordance with the
provisions of this Lease, or (iii) any sum which Landlord may expend or be
required to expend by reason of Tenant's default, including, without limitation,
any damage or deficiency in or from the reletting of the Premises as provided in
Section 23. The use, application or retention of the Collateral, or any portion
thereof, by Landlord shall not prevent Landlord from exercising another right or
remedy provided by this Lease or by law (it being intended that Landlord shall
not first be required to proceed against the Collateral) and shall not operate
as a limitation on any recovery to which Landlord may otherwise be entitled. If
any portion of the Collateral is used, applied or retained by Landlord for the
purposes set forth above. Tenant agrees, within 10 days after the written demand
therefor is made by Landlord, to deposit cash with the landlord in an amount
sufficient to restore the Collateral to its original amount.
 
     (b) If Tenant shall fully and faithfully comply with all of the provisions
of this Lease, the Collateral, or any balance thereof, shall be returned to
Tenant without interest after the expiration of the Term or upon any later date
after which Tenant has vacated the Premises. In the absence of evidence
satisfactory to Landlord of any permitted assignment of the right to receive the
Collateral, or of the remaining balance thereof, Landlord may return the same to
the original Tenant, regardless of one or more assignments of Tenant's interest
in this Lease or the Collateral. In such event, upon the return of the
Collateral, or the remaining balance thereof to the original Tenant, Landlord
shall be completely relieved of liability under this Section 26 or otherwise
with respect to the Collateral.
 
     (c) Tenant acknowledges that Landlord has the right to transfer or mortgage
interest in the Land and the Building and in this Lease and Tenant agrees that
in the event of any such transfer or mortgage, Landlord shall have the right to
transfer or assign the Collateral to the transferee or mortgagee. Upon, and only
upon, written acknowledgement of transferee's or mortgagee's receipt of such
Collateral, Landlord shall thereby be released by Tenant from all liability or
obligation for the return of such Collateral and Tenant shall look solely to
such transferee or mortgagee for the return of the Collateral.
 
     (d) The Collateral shall not be mortgaged, assigned or encumbered in any
manner whatsoever by Tenant without the prior written consent of Landlord.
 
     (e) Notwithstanding any thing to the contrary in this Section, Landlord
shall accord Tenant a credit annually against Rent in amount equal to interest
capable of being earned on said Collateral if said Collateral
 
                                       16
<PAGE>   38
 
were invested in a one-year Treasury Bill, purchased annually on the anniversary
date of the execution of this Lease.
 
     (f) In the event of the filing of a bankruptcy by Landlord, and the
Collateral is found to be a part of the bankrupt's estate, Tenant shall have the
right of set-off against any sums then due from Tenant to Landlord an amount
equal to the amount of the Collateral.
 
     (g) Notwithstanding anything in this Section to the contrary, Tenant
reserves to itself the right to secure the return of the Collateral from any
party, now or hereafter, who shall have the obligation to perform Landlord's
duties under the Lease.

                               ADDENDUM TO LEASE
 
     A-1. The Base Rent set forth in Section 3 and the Tenant's Proportionate
Share as defined in Subsection 4.A.(iv) are calculated on the basis that the
Premises consist of 4,513 square feet of rentable area of office space and
11,441 square feet of rentable area of computer space square feet of rentable
area contained in the Premises. Prior to the Commencement Date of this Lease,
Landlord shall cause the Premises to be measured, determine the actual number of
square feet of rentable area contained in the Premises, and recalculate the Base
Rent and the Tenant's Proportionate Share as follows: (A) the Base Rent set
forth in Section 3 shall be equal to the amount obtained by multiplying the
number of square feet of rentable office area contained in the Premises by
$10.25 per square foot per-annum; together with the amount obtained by
multiplying the number of square feet of rentable computer space contained in
the Premises by S14.00 per rentable square foot per annum, (B) the Tenant's
Proportionate Share shall be equal to the percentage calculated by dividing the
total rentable area of the Building set forth in Subsection 4.A.(iv) into the
total rentable area of the Premises. Promptly after Landlord has notified Tenant
of such determination and recalculations, Landlord certifies the following and
Landlord and Tenant agree to enter into an amendment to this Lease: (A) defining
the rentable area of the Premises, as determined by Landlord; (B) defining the
Base Rent as recalculated; and (C) defining the Tenant's Proportionate Share as
recalculated.
 
     A-2. In the event that the total rentable area of the Building or the
Premises increases or decreases during the Term, Landlord shall recompute the
Base Rent, if applicable (using the then-current Base Rent) and the Tenant's
Proportionate Share in accordance with A-1. Promptly after Landlord has notified
Tenant of such recomputation, Landlord and Tenant agree to enter into an
amendment to the Lease: (A) describing and designating the Premises to reflect
any increase or decrease, if applicable; (B) defining the Base Rent as
recomputed, if applicable; and (C) defining the Tenant's Proportionate Share as
recalculated.
 
     A-3. In the event that the number of square feet of rentable area in the
Premises or the Building as stated in the Lease or any amendment thereto is in
error, Landlord and Tenant agree to recompute, promptly after such error is
discovered, the Base Rent, if applicable (using the then-current Base Rent) and
the Tenant's Proportionate Share in accordance with Section A-1. Promptly after
such recomputation, Landlord and Tenant: (1) agree to enter into an amendment to
the Lease (A) setting forth the correct number of square feet of rentable square
feet in the Building and/or the Premises, as applicable (B) defining the Base
Rent as recomputed, and (C) defining the Tenant's Proportionate Share as
recomputed; and (2) agree to retroactively adjust Base Rent and the Tenant's
Proportionate Share as recomputed. If an error in the number of square feet in
the Premises or the Tenant's Proportionate Share previously resulted in Tenant
being overcharged, Landlord, upon discovery of the error, will retroactively
adjust the square footage and/or Tenant's Proportionate Share so as to accord

     Purchaser may, beginning July 1, 1992 and during the Option Period and
prior to the exercise of the Option, exercise a right of inspection by notice in
writing to Landlord. Upon exercise of its right of inspection, Tenant, its
agents and representatives shall be entitled, upon reasonable notice to Seller,
(i) to perform inspections and tests of the Building, including but not limited
to, all leased areas and structural and mechanical systems within the
Improvements; (ii) examine and copy any and all books and records maintained by
Seller or its agents relating to receipts and expenditures pertaining to the
Project for the three (3) most recent full calendar years and the current
calendar year; (iii) make investigations with regard to
 
                                        2
<PAGE>   43
 
zoning and building code requirements; and (iv) make market studies and real
estate tax analyses. Without limitation of the foregoing, Purchaser or its
designated independent accounts may audit the operating statements for the
Project at Purchaser's sole cost and expense and Seller shall supply such
documentation as Purchaser or its accountants may reasonably request to complete
such audit.
 
     Within five (5) days after receipt of notice of the right of inspection,
Landlord shall deliver to Tenant true, accurate and correct copies (or the
originals thereof for reproduction by Tenant) of the following:

     rent roll shall set forth with respect to each of the leases the following:
     the space covered thereby, the date and term thereof, renewal options, if
     any, the rent and other charges payable thereunder, including escalations
     and percentage rentals payable thereunder and the period for which such
     rents and other charges are in arrears or have been prepaid, the amount of
     security deposit thereunder, and the utilities, if any, which are furnished
     as part of the rent. Any rentable area in the Project that is vacant shall
     be shown on the rent roll;
 
          (ii) All certificates of occupancy, licenses, permits, authorizations,
     and approvals required by law and issued by all governmental authorities
     having jurisdiction over the Project as are in the possession of Landlord
     or its agents;
 
          (iii) All insurance policies currently in force and effect for the
     Project;

     the Project and a list of all employees of Landlord.
 
          (v) All existing policies of title insurance and surveys of the
     Property.
 
          (vi) All engineering and inspection reports for the Property.
 
          (vii) All mortgage documents.

     Tenant shall have until forty-five (45) days after receipt of all of the
documents referred to above (the "Feasibility Period") to investigate and
satisfy itself as to the feasibility and desirability of owning and operating
the Project. The notice of the right of inspection may be exercised by Tenant
three (3) more times during the Option Period. The documents to be delivered to
Tenant by Landlord for any additional Feasibility Periods shall supplement and
update the documents previously delivered. In the event that Tenant is not
satisfied for any reason with the result of its investigation, Tenant may, in
its sole discretion, elect not to exercise the Option. If the Option is not
exercised by Tenant during the Option Period, the Option shall terminate at the
end of the Option Period.
 
     Any changes, modifications, notices or new information with respect to the
above items (i) through (viii) made or received by Landlord at any time after
such items have been delivered to Tenant shall be delivered in writing to Tenant
immediately upon such change or modification or receipt by Landlord of such
notice or new information.
 
     Tenant acknowledges that, prior to the commencement of the Option Period,
Landlord may refinance the Property. Landlord hereby agrees that in the event of
any refinancing, to the extent that the new financing restricts prepayment of
the principal balance for any period during or after the Option Period, such
financing shall be upon terms which (i) are commercially reasonable in light of
then-prevailing market conditions for projects of a similar nature in the
metropolitan Chicago area; and (ii) will not interfere with or prohibit the
exercise by Tenant of its Option as set forth in this Section A-7.
 
     A-8.  Notwithstanding anything in the Lease or Exhibits thereto to the
contrary, Landlord's construction obligation to Tenant to prepare the Premises
for Tenant's occupancy shall consist of paying:

Notwithstanding anything herein to the contrary, Landlord also agrees to install
(at its own expense) throughout the Initial Office Space full height interior
doors of building standard-type finish, parabolic lenses, and upgraded ceiling,
as well as providing all necessary demolition, space plan(s), and architectural
and mechanical drawings for said Space. Landlord also agrees to provide and
install, at its own expense the chiller and related equipment and resulting
installation therefor, as detailed in Section 7.A. of the Lease.
 
The cost of installing the separate circuit and meter as described in Section
7.B. of the Lease shall be allocated as follows:
 
     1.    Landlord shall pay the first $5,000.00 thereof.
 
     2.    Tenant shall pay the next $5,000.00 thereof.
 
     3.    Landlord shall pay the next $5,000.00 thereof.
 
     4.    Tenant shall pay the next $5,000.00 thereof.

     (2)  $10.00 per rentable square foot of area in the Initial Computer Space
        for:
 
        (a)  Space plan(s), and architectural and mechanical drawings, (for
             which, collectively, a sum not exceeding $.80 per rentable square
             foot shall be allocated against the construction allowance).
 
        (b)  Demolition (for which a sum not exceeding $1.00 per rentable square
             foot shall be allocated), except that if the demolition costs more
             than said sum, Landlord shall pay the excess above $1.00 per
             rentable square foot.
 
        (c)  Buildout of said Premises per plans and drawings to be attached
             hereto as Exhibit A-B, and per Axelrod Construction Company's unit
             costs, attached hereto as Exhibit A-C.
 
             Any overage above said construction allowance shall be paid by
             Tenant.
 
     A-9.  Any portion of the construction allowance accorded by Landlord to
Tenant not otherwise utilized pursuant to Section A-8. shall be applied dollar
for dollar so as to: (1) increase the Base Rent abatement periods previously
granted Tenant at commencement of the Lease Term, (2) at Tenant's option may be
applied to the Base Rent abatement periods previously granted Tenant during
latter periods in the course of the Lease Term, or (3) at Tenant's option, may
be applied to Tenant's dollar obligation incurred, if any, in effecting a

of the Addendum to Lease, or (4) at Tenant's option, may be applied to Tenant's
cost of installing the separate circuit and meter described in Section 7.B. of
the Lease.
 
     A-10.  Landlord agrees to and will provide Tenant with a written report,
prior to the Commencement Date of the Lease Term, from a mutually agreeable,
certified and qualified engineer nominated by Tenant, certifying that the
existing computer room equipment and installation is functional and in good
working order. After the submission and acceptance of said certification,
Landlord shall have no continuing obligation to repair, restore, renovate, or
replace the computer room equipment/installation. The afore-mentioned
engineering certification shall address the following areas of concern and such
other aspects of the integral components of the computer room as may later
become apparent:
 
     (a)  Halon system -- Halon to be fully charged and operable.

        weekly) and secondary (monthly and annually) maintenance shall have been
        performed.

<PAGE>   45
 
     (f)  UPS systems -- checked, certified as operable and at full capacity.
 
     A-11.  Subject to rights of renewal, extension, option, or first refusal
accorded to the tenants in the Building prior to the execution of this Lease,
Tenant shall have the option, if it is not in default under this Lease, unless
Tenant is in the process of curing said default, to lease from Landlord, within
120 days from the Commencement Date of this Lease and on prior written notice
delivered to Landlord, on the same terms, including concessions, as are
contained in this Lease, all or any portion of the Building's rentable area
which, as of the date this Lease is executed by both parties hereto, is unleased
to any other party (hereinafter "Current Vacant Space").
 
     Notwithstanding anything in this Section A-11. to the contrary, the area of
the Building presently under lease to D.C. Northam Co. or under negotiation for
addition to the D.C. Northam Co. lease shall be dealt with as follows:
 
          Landlord represents to Tenant that Landlord is presently negotiating
     with said tenant relative to a renewal of said lease, and to include, in
     said renewal, an additional area consisting of approximately 1,600 square
     feet of rentable area. Notwithstanding the pending negotiations with D.C.
     Northam Co., Landlord agrees with Tenant herein that Landlord will not
     enter into a Lease Amendment with D.C. Northam Co. for said 1,600 square
     feet for a term expiring later than the termination date of D.C. Northam
     Co.'s existing lease. If D.C. Northam Co. leases said 1,600 square feet,
     upon the termination of the term thereof said space shall be considered
     Current Vacant Space, and all of the terms and conditions contained in
     Section A-11. and otherwise applicable to Current Vacant Space shall be
     equally applicable as to said 1,600 square feet. Landlord further agrees
     that any extension or renewal of lease for the existing D.C. Northam Co.
     space beyond the current termination date thereof shall be consistent with
     the notice provisions and Tenant's rights of Section A-13. of the Addendum.
     Notwithstanding anything in this Lease to the contrary, Tenant herein also
     expressly consents to Landlord leasing to Williams Electronics Co., Inc. an
     area consisting of approximately 9,000 square feet of area contained in
     what is currently space leased to United States Lines, Inc. on the first
     floor of the Building, for a five (5) year term. If said space is leased to
     said prospective tenant, said space on the termination of lease therefor
     shall also be treated as Current Vacant Space and thereafter available to
     Tenant herein on the terms and conditions as are contained in Section A-11.
     of this Lease.
 
     A-12.  If Tenant fails to exercise its option for Current Vacant Space,
pursuant to Section A-11. hereof, it shall nevertheless have a continuing right
of first refusal as to any portion of the Current Vacant Space which another
tenant or prospective tenant desires to lease from Landlord, on the following
terms and conditions:
 
     (1)  Landlord shall submit to Tenant herein any bona fide offers to lease
        space in the Building.
 
     (2)  Tenant shall thereafter have the right to match the business terms
        contained in the bona fide offer submitted to Section A-12.(1) above by
        advising Landlord in writing within thirty (30) days of receipt of any
        such bona fide offer of its intent to Lease the premises by said offer
        on the same terms and conditions as are contained therein.
 
     (3)  If Tenant herein fails to advise Landlord of its intent to lease said
        premises within said period of time or refuses to lease said premises on
        the terms and conditions as are contained in said bona fide offer,
        Tenant's rights of first refusal shall be waived as to said space, if
        the other tenant or prospective tenant does, in fact, lease said
        premises. If the terms and conditions in said bona fide offer change
        during the course of negotiation with the Tenant or prospective tenant
        and a lease is executed by Landlord pursuant thereto, said lease shall
        be null and void and Tenant herein shall be entitled to receive
        consequential damages resulting from its loss therefrom.
 
     (4)  If Tenant herein does exercise its right of first refusal as to said
        premises, Tenant and Landlord shall, as soon as is practicable
        thereafter, enter into a Lease Amendment incorporating said premises
        into the Premises demised by Landlord to Tenant.
 
     (5)  The right of first refusal as to Current Vacant Space shall be a
        continuing right; i.e.; if the subject premises are leased to another
        tenant or prospective tenant, Tenant herein shall have the right to
 
                                        5
<PAGE>   46
 
        lease the subject premises from Landlord pursuant to this Section A-12.
        upon the expiration of said other tenant or prospective tenant's lease.
 
     (6)  Landlord further agrees with Tenant herein that it shall not hereafter
        lease any portion or all of the Current Vacant Space to another tenant
        or prospective tenant for a period of more than five (5) years,
        including renewals, option terms, or extensions, without first obtaining
        the consent of Tenant herein, said consent not to be unreasonably
        withheld.
 
     A-13.  Landlord further agrees that as to any space in the Building
hereafter vacated by a tenant under lease in the Building as of the date of the
execution of this Lease, by reason of the termination of said tenant's lease or
lease term, Landlord will provide Tenant with 300 days prior written notice
thereof, (if Landlord, in fact, has 300 days prior knowledge of said
termination) and Tenant herein shall thereafter have the right to lease said
space to be vacated as follows:
 
     (1)  Within 105 days of the receipt notice from Landlord to Tenant of the
        expected vacating of said space, on the same terms and conditions as are
        then applicable to the Premises demised hereby, (except that the
        abatement of Rent shall be ratably reduced for said space, pursuant to
        the formula for ratable reduction of construction, as contained in
        Section A-17.), or
 
     (2)  Thereafter, pursuant to the rights of first refusal accorded to Tenant
        herein pursuant to Section A-11. and A-12. (except that the abatement of
        Rent shall be ratably reduced for said space, pursuant to the formula
        for ratable reduction of construction, as contained in Section A-17.).
 
     A-14.  Landlord further agrees that as to any space in the Building
hereafter vacated by a tenant not under lease in the Building as of the date of
the execution of this Lease (hereafter "Intervening Tenant"), by reason of the
termination of said tenant's lease or lease term, Landlord will provide Tenant
herein with 300 days prior written notice thereof (if Landlord, in fact, has 300
days prior knowledge of said termination), and Tenant herein shall thereafter
have the right to lease said space to be vacated by the Intervening Tenant as
follows:
 
     (1)  Within 105 days of the receipt of notice from Landlord to Tenant of
        the expected vacating of said space, on the same terms and conditions as
        are then applicable to the Premises demised hereby, (except that the
        abatement of Rent shall be ratably reduced for said space, pursuant to
        the formula for ratable reduction of construction, as contained in
        Section A-17.), or
 
     (2)  Thereafter, Tenant shall have the rights of first refusal accorded it
        herein pursuant to Section A-11. and A-12. (except that the abatement of
        Rent shall be ratably reduced for said space, pursuant to the formula
        for ratable reduction of construction, as contained in Section A-17.).
 
        Landlord shall use its best efforts in negotiating lease(s) with
        Intervening Tenant(s) to assure that Landlord shall have the right under
        said lease(s) to substitute premises, if required, for said Intervening
        Tenant(s).
 
     (3)  If said space is vacant and Landlord fails to procure a new tenant for
        it, Tenant having failed to lease it from Landlord pursuant to A-14. (1)
        above, Tenant shall nevertheless have a continuing right, absent
        exercise of its first refusal rights accorded in A-14.(2), to lease said
        space from Landlord, on all the terms and conditions applicable to
        Intervening Tenant space, except that the rental terms, including any
        concessions customarily being offered for like space at that time in the
        Oak Brook market, shall be the then fair market value for said space.
 
        In case of a dispute between Landlord and Tenant as to said rental
        terms, the dispute will be submitted to a binding arbitration process,
        involving a qualified broker and/or appraiser, with the associated costs
        divided equally between Landlord and Tenant and a result obtained in 30
        - 40 days from date of submission.
 
     A-15.  The rights of first refusal accorded Tenant by Landlord pursuant to
Sections A-13. and A-14. shall be recurring and continuing; i.e.; if Tenant
fails or chooses not to exercise its rights when first applicable, said rights
of first refusal shall nevertheless survive said initial failure and thereafter
be available to Tenant herein, when next available.
 
                                        6
<PAGE>   47
 
     As to any offer(s) to lease space to another tenant or prospective tenant,
Tenant herein shall be advised by Landlord of any changes in business terms
after Landlord's initial offer(s).
 
     A-16  Landlord's construction obligation to Tenant herein to prepare the
original Premises for Tenant's occupancy shall consist of:
 
     (1) the turnkey construction for the Initial Office Space, pursuant to
        Section A-8.
 
     (2) $10.00 per rentable square foot for each square foot of Initial
        Computer Space.
 
     Said construction allowances are intended to pay for space plan(s),
architectural and mechanical drawings, (which costs, collectively, shall be
accorded an allowance not exceeding $.80 per rentable square foot; as in Section
A-8. (2) (a) herein, demolition, and construction of a permanent nature
(including wiring and installation thereof) excluding, for example, but not
limited to: furniture, trade fixtures, telephone and computer equipment (all as
detailed in Section A-8. herein).
 
     Any additional construction costs are to be borne solely by Tenant, except
that Landlord shall be solely responsible for paying all costs associated with
installation of air conditioning necessary to comply with Landlord's obligation
pursuant to Section 7. of Lease relative to the difference between the 4,513
square feet of rentable area (Initial Office Space) and the 10,000 rentable
square feet of potential office space, or a difference of 5,487 rentable square
feet.
 
     A-17.  Landlord's construction obligation as to any space in the Building
presently built out as office space which Tenant leases from Landlord subsequent
to the Premises originally demised, shall be ratably reduced from $20.00 per
rentable square foot allowance; e.g.; if Tenant leases space at a point in time
when 10% of its Term has expired, Landlord's construction obligation shall be
reduced to $18.00 per rentable square foot.
 
     As to any space in the Building built out as office space at the time this
Lease is executed and subsequently leased by Tenant and used as computer space,
Landlord's construction obligation shall consist of paying $20.00 per rentable
square foot, ratably reduced pursuant to the above formula in relation to the
amount of the Term remaining when said space is leased. Said primary costs shall
be paid by Landlord and Landlord shall not be entitled to a refund of same.
Landlord, however, agrees to pay any and all additional construction costs
associated with said build-out. To the extent any such additional costs exceed
the result of the construction formula associated with said secondary space,
Landlord shall advance said costs, but Tenant shall repay Landlord for those
advances, fully amortizing said sum over the balance of the Term then remaining,
together with interest at a rate equivalent to 100 basis points above the United
States Treasury Department's cost of borrowing for the same period of time, in
equal monthly installments, together with Rent, and as Rent.
 
     Notwithstanding the contents of this Section A-17. to the contrary,
Landlord's $20.00 per rentable square foot construction obligation for computer
space leased as of the date of the execution of this Lease may be applied to:
 
     (1)  construction, or
 
     (2)  additional abated Base Rent otherwise due for said computer space, or
 
     (3)  any costs to be borne by Tenant associated with the buyout, if any, of
        Computer Sciences Corporation's lease for computer space.
 
     A-18.  All options to add space and/or exercise of rights of first refusal
shall, under all circumstances, reflect a Termination Date which is the same as
the Termination Date of the Premises originally demised.
 
     A-19.  Only Base Rent is abated pursuant to Section A-4.; Tenant shall have
the obligation to pay from the Commencement Date of this Lease its proportionate
share of all Taxes and Operating Expenses, as said terms are defined in the
Lease.
 
     A-20.  Upon notice from Tenant to Landlord, Landlord and Tenant agree to
use their best efforts to negotiate a termination of the lease between Landlord
and Computer Sciences Corporation for that tenant's computer space in the
Building. Landlord agrees to pay the first $50,000.00 required to effect such a
termination; any amounts above $50,000.00 required to effect a termination will
be paid by Tenant herein.

     A-21.  If Tenant is not in default, or is in the process of curing said
default, and on written notice delivered to Landlord no later than twelve (12)
months prior to the end of the Term of this Lease, Tenant shall have the right
to renew this Lease for an additional term of five (5) years, commencing
September 1, 2002 and terminating August 31, 2007 (hereafter "First Extended
Term"), on all the terms and conditions of this Lease, except as follows:
 
     (1)  There shall be no abatement of Rent.
 
     (2)  Landlord's construction obligation as to any space not leased by
        Tenant prior to the Commencement of the First Extended Term shall
        consist of paying the cost of a then-building standard buildout. If the
        First Extended Term expires and Tenant has not renewed the Lease for the
        Second Extended Term, Tenant will refund to Landlord on or by August 31,
        2007, an amount equal to the unamortized cost of said buildout, based on
        a five (5) year amortization schedule, e.g.; if Tenant leases space for
        the first time at the end of the second year of the First Extended Term,
        and the then-building standard buildout is $15.00 per rentable square
        foot, and Tenant does not renew pursuant to Section A-22., Tenant will
        owe Landlord on or by August 31, 2007 the sum of $6.00 per rentable
        square foot so leased ($15.00 X 40% = $6.00/rentable square foot).
 
     (3)  Tenant shall have no right to cancel or terminate the Term of Lease.
 
     (4)  The Base Rent for said First Extended Term shall be an amount, on a
        per rentable square foot per annum basis, which is the greater of:
 
        (a)  Tenant's Base Rent rate as of the commencement of the First
             Extended Term, or
 
        (b)  80% of the then fair market value for equivalent space in the Oak
             Brook Market.
 
     A-22.  If Tenant is not in default, or in the process of curing said
default, and on written notice delivered to Landlord no later than twelve (12)
months prior to the end of the First Extended Term of this Lease, Tenant shall
have the right to renew this First Extended Term for an additional term of five
(5) years, commencing September 1, 2007 and terminating August 31, 2012
(hereafter "Second Extended Term"), on all of the terms and conditions of this
First Extended Term, except as follows:
 
     (1)  There shall be no abatement of Rent.
 
     (2)  Landlord's construction obligation as to any space not leased by
        Tenant prior to the commencement of the Second Extended Term shall
        consist of paying the cost of a then-building standard buildout ratably
        reduced by the percentage of the Second Extended Term that has expired
        prior to the commencement date of the lease term for said space; e.g.;
        if Tenant leases space for the first time at the end of the second year
        of the Second Extended Term, and the then-building standard buildout is
        $15.00 per rentable square foot, Landlord's construction obligation
        therefor shall be $9.00 per rentable square foot so leased ($15.00 X 60%
        = $9.00/rentable square foot).
 
     (3)  Tenant shall have no right to cancel or terminate the Term of Lease.
 
     (4)  The Base Rent for said Second Extended Term shall be an amount, on a
        per rentable square foot per annum basis, which is the greater of:
 
        (a)  Tenant's Base Rent rate as of the commencement of the Second
             Extended Term, or
 
        (b)  80% of the then fair market value for equivalent space in the Oak
             Brook market.
 
     A-23.  At any time after the execution of this Lease, but before the
Commencement Date hereof, Tenant shall have the right to enter into the Premises
to test the facilities therein and set up necessary equipment, and, pursuant to
this Lease, to occupy the Initial Computer Space at any time, and the Initial
Office Space after completion of its reconstruction. Landlord shall cooperate
fully in granting access to Tenant therefor, but shall impose such reasonable
requirements as are necessary to assure security for, and control of, the
Building. During such period of time prior to the Commencement Date hereof,
Tenant agrees to hold Landlord harmless from any damage, liability or claims it
may suffer as a result of Tenant's activities and to indemnify Landlord for any
losses, claims, damage, or liability (except as same result from Landlord's
gross negligence) Landlord may suffer by reason of Tenant's activities in the
Premises. All of the applicable provisions of this Lease relating to
construction, insurance, covenant against liens, possession, repairs, fire and
 
                                        8
<PAGE>   49
 
casualty, rules and regulations, shall be equally applicable during this period
of time prior to the Commencement Date.
 
     A-24.  Prior to signage other than building standard signage, tenant shall
have the right to erect and the obligation to maintain, both at its sole cost,
any desired signage in the interior or on the exterior of the Building, subject
to Landlord's consent, not to be unreasonably withheld, and further subject to
applicable rules and ordinances of any governmental body, including, but not
limited to, the Village of Oak Brook. Tenant's signage rights, subject to this
Section, shall be exclusive to Tenant only (and not accorded to any other tenant
or prospective tenant in the Building) after such time as Tenant herein has
leased one-half or more of the rentable square feet in the Building; at that
point in time, Tenant shall also have the right to rename the Building, subject
to Landlord's consent, not to be unreasonably withheld.
 
     A-25.  The uninterrupted power supply system (UPS) presently in the
Building will be maintained jointly by Landlord, Tenant, and Computer Sciences
Corporation, with Tenant paying its proportionate share of the cost of said
maintenance. Tenant will immediately utilize its best efforts to negotiate with
Computer Sciences Corporation a joint maintenance agreement of the UPS system.
If such an arrangement is made, Landlord's maintenance obligation shall be
waived.
 
     Landlord's maintenance obligation, so long as it exists hereunder, shall be
undertaken with a responsible and qualified maintenance firm. Landlord and
Tenant shall use their best efforts to agree on a maintenance contractor; in the
event the parties fail to reach agreement, Landlord shall have the right to
choose the contractor.
 
     A-26.  Tenant shall have the exclusive right to use five (5) assigned
covered parking spaces and five (5) assigned uncovered parking spaces on the
parking lot of the Building during the Term of Lease, or any renewal thereof,
without charge, as agreed upon by Landlord, and Tenant as shown on Exhibit E. At
such time as Tenant leases from Landlord additional space beyond the Premises
originally demised, Landlord agrees to provide Tenant with additional, exclusive
assigned parking spaces at the ratio of one parking space per 1,000 square feet
of rentable area so leased, on the parking lot of the Building, for the Term of
the Lease, or any renewal thereof, without charge, as agreed upon by Landlord,
and Tenant, with one-half of said spaces being covered and one-half uncovered.
 
     A-27.  In addition to the Option granted to Tenant in section A-7. hereof,
Tenant has the following rights:
 
     In the event that Landlord receives a bona fide offer (the "Offer") from a
third party to purchase the Property which Landlord desires to accept, Landlord
shall first give written notice (the "Notice") thereof to Tenant. The Notice
must be received by Tenant not less than thirty (30) days before the proposed
sale and shall state the date of the proposed sale, the name and address of the
proposed purchaser, and shall include a copy of the Offer specifying the terms
and conditions of the proposed sale. Within thirty (30) days after the receipt
of the Notice, Tenant shall have a right of first refusal to purchase the
Property on the terms and conditions set forth in the Offer except as to the
proposed date of sale contained therein. If Tenant exercises its right of first
refusal to purchase the Property, by written notice to Landlord, Tenant and
Landlord shall, as soon as is practicable thereafter, enter into a contract for
sale and purchase of the Property on the same terms and conditions as contained
in the Offer except the date of sale shall be sixty (60) days after exercise of
the right of first refusal.
 
     The right of first refusal accorded Tenant by Landlord pursuant to this
Section A-28 shall be recurring and continuing; i.e., if Tenant chooses not to
exercise its right when first applicable, and the Property remains unsold, the
right of first refusal shall nevertheless continue to be available to Tenant,
when next applicable. As to any Offer from any prospective purchaser to purchase
the Property, Landlord shall advise Tenant of any changes in terms or conditions
from those contained in the Offer attached in the Notice, whereupon Tenant shall
have thirty (30) additional days in which to exercise the right of first refusal
as set forth herein.
 
     A-28.  Except as amended, modified, or supplemented hereby, all of the
terms and conditions of the Lease and Exhibits thereto shall remain in full
force and effect. Wherever there is a conflict between the Lease (and Exhibits
thereto) and this Addendum, the Addendum shall control and prevail.

Gentlemen:
 
     You (hereinafter called "Tenant") and we (hereinafter called "Landlord"),
are executing simultaneously with this letter agreement a written lease (the
"Lease") covering certain premises, as more particularly described in said
lease, in the building known as 815 Commerce Drive.
 
     To induce Tenant to enter into the Lease (which is hereby incorporated by
reference to the extent that the provisions of this letter agreement may apply
thereto) and in consideration of the mutual covenants hereinafter contained,
Landlord and Tenant agree as follows:
 
     1. (a) Landlord, at Landlord's cost and expense (as detailed in A-8. to
Addendum to Lease) shall do the work outlined in accordance with Axelrod
Construction Co.'s unit costs, attached as Exhibit A-C, and quantity breakdown"
identified by Landlord and Tenant and attached hereto (hereinafter called
"Work"). Landlord shall pay for the necessary initial architectural drawings for
the work (hereinafter called "Plans") to be drawn at a cost (as detailed in A-8.
to Addendum to Lease), by Tenant's space planner and engineer. The Plans must
include partition drawings, telephone and electric drawings and reflected
ceiling drawings and must be suitable in all respects for submission to the
Building Department of the village of Oak Brook in order to obtain a building
permit. All of the Plans are expressly subject to Landlord's written approval.
Tenant has assured itself by direct communication with its space planner or
architect that the Plans can be delivered to Landlord by Tenant on or before
June 15, 1987, provided that Tenant promptly furnishes complete information
concerning Tenant's requirements with respect to the Work to said space planner
or architect as and when requested by them. Tenant covenants and agrees to cause
said Plans to be delivered to Landlord on or before said date. Landlord will, at
Landlord's sole cost and expense, have mechanical (sprinkler, air conditioning,
heating, electric and plumbing) drawings prepared by Landlord's mechanical
engineer covering, and limited to, the mechanical elements of the Work as shown
on the Plans as the Work relates specifically to Building Standard installations
as set forth in Addendum hereto.
 
     (b) Except as set forth in subparagraph (a), Landlord has no other
agreement with Tenant and has no other obligation to do any other work with
respect to said premises. Any other work in said premises which may be permitted
by Landlord pursuant to the terms and conditions of the Lease shall be done at
Tenant's sole cost and expense and in accordance with said terms and conditions.
 
     2. If Landlord further agrees to perform, at Tenant's request and upon
submission by Tenant (at Tenant's sole cost and expense) of all necessary
drawings, plans and specifications, any other work in addition to the Work
described in Paragraph 1 hereof, such other work to be done at Tenant's sole
cost and expense as a Tenant's extra. Prior to commencing any such other work
requested by Tenant. Landlord shall submit to Tenant written estimates of the
cost of such other work. If Tenant shall fail to approve said estimates within
seven (7) days from the receipt thereof, the same shall be deemed disapproved in
all respects by Tenant and Landlord shall not be authorized to proceed thereon.
Tenant agrees to pay to Landlord promptly upon being billed therefor, at any
time and from time to time, the cost of all such other work together with ten
percent (10%) of said cost for Landlord's overhead. Landlord shall not charge a
fee for itself for the initial construction.
 
     3. Notwithstanding the date provided in the Lease for commencement of the
term thereof, Tenant's obligation to pay rent thereunder shall not commence
until Landlord shall have substantially completed all of
<PAGE>   53
 
the Work to be done by Landlord as described in Paragraph 1 hereof; provided,
however, that if Landlord shall be delayed in substantially completing said work
as a result of
 
     (a)  Tenant's failure to furnish the Plans for the Work in accordance with
        paragraph 1 hereof, or
 
     (b)  Tenant's failure to approve cost estimates within the time specified
        in paragraph 2 hereof, or
 
     (c)  Tenant's request for materials, finishes or installations other than
        Building Standard, or
 
     (d)  Tenant's changes in the Work or the Plans thereof (notwithstanding
        Landlord's approval of such changes); or
 
     (e)  The performance of any work by Tenant or any person, firm or
        corporation employed by Tenant; or
 
     (f)  Any fault of Tenant or its agents,
 
the commencement of the term thereof and the payment of rent thereunder shall
not be affected or deferred on account of such delay.
 
     4. Landlord, at Landlord's discretion, may permit Tenant and Tenant's
agents to enter said premises prior to the date specified as the commencement of
the term of the Lease in order that Tenant may do such other work as may be
required by Tenant to make said premises ready for Tenant's use and occupancy
thereof. If Landlord permits such entry prior to commencement of the term, then
such permission however, is conditioned upon Tenant and Tenant's agents,
contractors, workmen, mechanics, suppliers and invitees, working in harmony and
not interfering with Landlord and Landlord's agents in doing Landlord's work in
said premises or for other tenants and occupants of said building. If at any
time such entry shall cause or threaten to cause such disharmony or
interference, Landlord shall have the right to withdraw such permission upon
twenty-four (24) hours written notice, to Tenant. Tenant agrees that any such
entry into and occupation of the premises shall be deemed to be under all of the
terms, covenants, conditions and provisions of the Lease except as to the
covenant to pay rent, and further agrees Landlord shall not be liable in any way
for any injury, loss or damage (except for the negligence of Landlord, its
agents, employees, servants, contractors and invitees) which may occur to any of
Tenant's work and installations made in said premises or to properties placed
therein prior to the commencement of the term of the Lease, the same being at
Tenant's sole risk.
 
     5. Notwithstanding anything in this Exhibit or in the Lease to the
contrary, Tenant shall have the right, as to construction work performed after
the work associated to install Tenant in the Premises, to choose its own
contractor if its bid is lower and/or bid out said work. If Tenant thereafter
engages its own contractor to perform the requisite construction, Landlord shall
have no supervisory capacity as to said contractor, but said contractor shall:
 
     (a)  Provide Landlord with a current certificate of insurance, satisfactory
        in content and coverage.
 
     (b)  Adhere to the then-prevailing practice in Oak Brook relative to the
        hiring of union personnel for the construction.
 
     (c)  Provide Landlord with a performance bond for the subject construction.
 
     (d)  Possess a current contractor's license enabling it to perform
        construction in Oak Brook.
 
     (e)  Certify to Landlord that it has, for each of the three (3) years
        previous to the subject construction, performed and completed similar
        construction in an amount of not less than $2,000,000.00 in value.
 
     Any such Tenant-contracted construction shall be performed in a timely,
diligent and workmanlike manner and Tenant shall be solely responsible for the
quality of such work.
 
     Tenant agrees to indemnify and hold Landlord harmless from any claims
arising from, or as a result of, any such Tenant-contracted construction.
 
     If the foregoing correctly sets forth our understanding, kindly sign as
indicated below.

                                            RE: GIS Information Systems
                                                815 Commarce Dr., Oakbrook
Dear Larry:

     Following is a description of the new H.V.A.C. system being designed to
serve the GIS Information Systems offices at 815 Commarce Drive.

     The existing H.V.A.C. is located on the second floor and serves all
tenant space on that floor with the exception of the computor room.
The new tenant space will be diconnected from this system and a new
system will be installed to serve only this space.

     The new system will be a roof top variable volume System, designed
to operate 24 hours a day 365 days per year. This system will provide both
heating and cooling for the tenant space. The system components and 
operation is as follows.

     The main air handler and refrigeration equipment will be a package unit
     with a capacity of approx. 30 tons of refrigeration located on the roof
     above the tenant space. This package unit will provide both the
     ventilation air and cooling for the space. The unit will have a
     economizer cycle to provide free cooling when the outside air temperature
     is low enough to satisfy the space requirements. The control to start and
     stop the unit will be located in tenant space. Conditioned air to
     the perimeter rooms will be delivered to variable volume fan powered boxes
     with hot water heating coils controlled by automatic valves. Interior
     rooms will be served by variable volume boxes. Each box will be considered
     as a control zone operated by a thermostat to provide independent
     control of the space served. Each control zone will serve multiple rooms as
     long as they have the same outside exposure and usage. Space such as
     conference rooms will have independent control for each room.

                            S.H. COHEN & ASSOCIATES
                  Consulting Mechanical & Electrical Engineers

     Fan powered boxes operate as variable volume boxes as long as heating is
     not required, when heating is required the fan and coil are activated 
     automatically by a thermostat to provide a constant heated air flow to
     the space. The variable volume box provides a variable air flow to the
     space by controlling a damper in the box. The control of both boxes is
     accomplished by a thermostat located in the space served. The system is
     very flexible and additional control zones can be added if the tenant so
     desires. The hot water system used to provide heat to the box will be
     provided by the existing building system. The building hot water system
     operates 365 days a year so hot water is always available.

     The system I have just described is very energy conserving and the 
     present state of the art. If you require any additional information as to 
     the exact operation of each component I will be happy to provide you with 
     a detailed description.




                                                                      Sincerely:

    warranties (the "Intangible Personal Property"); and (e) Seller's interest
    in all leases and other agreements to occupy the Improvements, or any
    portion thereof, as amended from time to time (the "Leases").

2.  Purchase Price.

    The purchase price to be paid to Seller by Purchaser is $8,300,000.00 for
    the Project (the "Purchase Price"). The Purchase Price, plus or minus
    prorations, shall be paid at Closing (as hereinafter defined) by wire
    transfer or other immediately available funds.

                                       1

3.  Closing.

    The purchase and sale contemplated herein shall be consummated at a closing
    (the "Closing") to take place at the office of Chicago Title Insurance
    Company (the "Title Insurer") at 111 W. Washington, Chicago, Illinois, on
    the date sixty (60) days after the date hereof, or at such other time as
    the parties may agree upon in writing. The closing date in effect from time
    to time shall be referred to as the "Closing Date." Seller shall deliver
    possession of the Project to Purchaser at Closing.

    For the purpose of this Contract, in computing any period of time
    prescribed or allowed by this Contract, the day of the act or event from
    which the designated period of time begins to run shall not be included,
    but the last day of the period so computed shall be included, unless it is
    a Saturday, a Sunday or a holiday as defined or fixed in any statute now
    or hereafter in force in the State of Illinois, in which event the period
    runs until and includes the next day which is not a Saturday, a Sunday or
    such a holiday.

4.  Earnest Money.

    Purchaser has delivered to Seller its earnest money check in the amount of
    $100,000.00, made payable to the Title Insurer (the "Earnest Money"), which
    shall be deposited in a deed and money escrow at the Title Insurer pursuant
    to a deed and money escrow agreement in the form then in use by the Title
    Insurer as modified to conform with this Contract and, at the request of
    Purchaser, shall be invested in accordance with Purchaser's directions. All
    interest earned thereon shall accrue for the benefit of the Purchaser and
    shall be paid to Purchaser upon Closing or the termination of this
    Contract, unless the Earnest Money is paid to Seller as a result of
    Purchaser's default, in which event the interest shall be paid to Seller.
    Seller shall execute and deliver all documentation as requested by
    Purchaser or the Title Insurer in order to effectuate the foregoing.

5.  Feasibility Period.

    The parties hereby acknowledge that this Contract is being executed
    pursuant to an option to purchase the Project, as contained in Paragraph
    A-7 of that certain lease (the "GIS Lease") dated June __, 1987 by and
    between LaSalle National Bank, not personally but as Trustee under Trust
    Number 107194, and 815 Commerce Drive REIP, as landlord, and GIS
    Information Systems, Inc., an Illinois corporation, as tenant. Pursuant to
    the GIS Lease, Purchaser was granted a period of time (the "Feasibility
    Period") during which it was allowed to inspect the Project prior to the
    exercise of its option to purchase the Project. Notwithstanding anything to
    the contrary contained in this Contract, no act or

                                       3
<PAGE>   70

    failure to act by Purchaser or its agents to verify the accuracy of
    Seller's warranties and representations set forth in this Contract, shall
    in any way affect the binding nature of such warranties and representations
    nor the liability of Seller for any breach thereof.

6. Title and Survey Matters.

(a)    No later than thirty (30) days after acceptance of this Contract by
       Seller, Seller will deliver to Purchaser, at Seller's sole cost and
       expense, (i) a title commitment (the "Title Commitment") dated on or
       after the date hereof issued by the Title Insurer committing to issue to
       Purchaser an ALTA Form B owner's policy of title insurance with respect
       to the Project in a nominal amount (which shall be increased to the
       amount of the Purchase Price, not later than fifteen (15) days prior to
       Closing) showing fee simple title in Seller (the "Title Policy") and
       (ii) copies of all documents, whether recorded or unrecorded, referred
       to in the Title Commitment. The Title Commitment shall show title
       subject only to (i) the general exceptions contained in the policy with
       an extended coverage endorsement over general exceptions 1 through 5,
       (ii) the title exceptions set forth in Exhibit "B" attached hereto and
       made a part hereof (the "Permitted Exceptions"), and (iii) title
       exceptions pertaining to liens or encumbrances of a definite or
       ascertainable amount which may be removed by the payment of money at
       Closing and which Seller may so remove at that time by using funds to be
       paid upon delivery of the deed hereunder (the "Abatement Exceptions").
       The Title Commitment shall also include a Restrictions Endorsement 1, a
       Location Endorsement and a 3.1 Zoning Endorsement. If the Title
       Commitment discloses any exceptions to title other than the Permitted
       Exceptions and the Abatement Exceptions, and if Seller for any reason
       cannot have such other exceptions waived or insured over (provided, that
       if such exceptions can be waived or insured over they shall be deemed to
       be "Abatement Exceptions") Purchaser, at its option may elect' by
       notifying Seller within ten (10) days after receipt of the Title
       Commitment, the aforesaid title documents and the Survey referred to in
       subparagraph (b) below, to terminate this Contract in which event the
       Earnest Money shall be returned to Purchaser and neither party shall
       have any further liability to the other.  If no such notice is given,
       this Contract shall remain in full force and effect and any such other
       exceptions shown in the Title.Commitment shall be deemed to be among the
       "Permitted Exceptions" except that Seller shall, subject to the
       provisions of subparagraph (d) below, at its sole cost, cause the
       Abatement Exceptions to be removed or insured over prior to or at the
       Closing. Seller shall, at its sole cost,

                                       3
<PAGE>   71
       cause the Title Commitment to be later dated effective as of fifteen
       (15) days prior to Closing, said later dated Title Commitment to be
       delivered to Purchaser no later than ten (10) days prior to Closing, and
       cause the Title Policy to be issued as of the Closing Date to cover the
       recording of the deed to be delivered by Seller, as provided herein.


(b)    No later than thirty (30) days from the date of Seller's acceptance of
       this Contract, Seller will deliver to Purchaser, at Seller's sole cost
       and expense, six (6) prints of an as-built, spotted survey of the Real
       Estate and Improvements (the "Survey") prepared by a surveyor registered
       in the State of Illinois and certified by said surveyor to have been
       prepared in accordance with minimum detail requirements of the American
       Land Title Association land survey standards as of a date on or after
       the date hereof, said certificate to be certified to Purchaser, its
       nominee, lender and the Title Insurer. Without limitation of the
       foregoing, the Survey shall state the legal description of the Real
       Estate; the square footage thereof; shall show the location of the
       Improvements (including distances from perimeter lot lines); all
       easements and other agreements of record over the Real Estate; easements
       or other agreements over property other than the Real Estate for the
       benefit of the Project and shown in the Title Commitment; and adjacent
       public streets and ways (showing name and width of street). The surveyor
       shall also certify that the Real Estate is not located in a flood plain.
       Any encroachment over a lot line, a prohibited encroachment over any
       easement or any other matter shown on the Survey which other matter does
       or could in the future materially interfere with the use, operation or
       financing of the Project or render title thereto unmarketable is
       referred to herein as a "Survey Defect." If the Survey contains any
       Survey Defects, Purchaser may elect, by written notice delivered to
       Seller within ten (10) days after receipt of the Survey to (i) terminate
       this Contract, in which event, the Earnest Money shall be returned to
       Purchaser and neither party shall have any further liability to the
       other, or (ii) direct Seller to comply with the provisions of
       subparagraph below.

(c)    Seller shall deliver to Purchaser no later than twenty (20) days prior
       to the Closing Date, at its sole cost and expense, searches, dated on or
       after thirty (30) days before the Closing Date, of the records of the
       Recorder of Deeds of DuPage County, Illinois and the Secretary of State
       of Illinois for all UCC financing statements showing Seller and Seller's
       management agent as debtor (the "Lien Searches").

                                       4
<PAGE>   72

(d)    In the event the later dated Title Commitment, Survey or Lien
       Searches disclose any unpermitted claim, lien, encumbrance or other
       defect, including without limitation Abatement Defects and Survey
       Defects or the Title Insurer refuses to issue the endorsements
       to the Title Policy described in subparagraph (a) above (the
       "Defect"), Seller shall, prior to Closing, cause such Defect to be
       removed or insured over by the Title Insurer not less than ten (10)
       days prior to Closing, or such later time as Purchaser, in its sole
       discretion, shall permit. If any Defect is not so removed or
       insured over not less than ten (10) days prior to Closing, Purchaser,
       may, at its sole option, either (i) terminate this Contract by
       written notice to Seller, in which event the Earnest Money shall
       be returned immediately to Purchaser, and neither party shall have
       any further liability to the other, except that Seller shall be
       liable to Purchaser for Purchaser's actual out-of-pocket expenses
       incurred in connection with this Contract and the Feasibility Period,
       or (ii) proceed to close the purchase of the Project and deduct
       from the Purchase Price payable at Closing such sums as Purchaser
       may deem necessary to remove, or cause the Title Insurer to insure
       over, such Defect.

7.  Seller's Representations and Warranties.

    Seller represents and warrants to, and covenants with, Purchaser that the
    following matters are and shall be true as of the date of execution of this
    Contract and as of the Closing Date:

(a)    The leases delivered to Purchaser during the Feasibility Period (the
       "Leases") constitute the entire agreement with each tenant. No tenant
       has any right to renew or extend its Lease except as shown on the rent
       roll ("Rent Roll") delivered to Purchaser during the Feasibility Period
       as the same have been or will be updated as required in the GIS Lease or
       elsewhere in this Contract. There are no leases, tenancies, or other
       rights of occupancy or use for any portion of the Project other than as
       set forth in the Leases.


(b)    None of the Leases and none of the rents or other amounts payable
       thereunder have been assigned, pledged, or encumbered except to the
       first mortgage lender; any such assignment, pledge or encumbrance will
       be released at or prior to Closing unless Purchaser takes title to the
       Project subject to such mortgage as provided elsewhere in this Contract.
       There are no valid claims of offset or defenses to the payment of rents
       and each of the tenants is in fact paying and performing and is legally
       required to pay and perform all sums and obligations set forth in the
       Leases.




                                       5
<PAGE>   73

(c)    Except as otherwise provided in Exhibit "C" attached hereto, no
       brokerage or leasing commissions, management fees or other compensation
       are due or payable to any person, firm, corporation, or other entity
       with respect to or on account of any of the Leases or any extensions or
       renewals thereof. Any such commissions, fees or other compensation as
       are identified on Exhibit "C" shall remain the obligation of Seller and
       Seller agrees to indemnify, defend and save harmless Purchaser from any
       such liability. All brokerage or leasing commissions and tenant
       build-out concessions and allowances payable in conjunction with any
       Lease entered into on or after the date hereof, will be the
       responsibility of Purchaser and shall be paid by Purchaser, except that,
       if any tenant under any lease entered into on or after the date hereof
       is required to make payments of rent after execution of this Contract
       but prior to Closing, any commissions or concessions made with respect
       to such lease shall be prorated at Closing.


(d)    No tenant or other occupant under any of the Leases and no other person,
       firm, corporation, or other entity has any right or option to acquire
       the Property or any portion thereof.

(e)    Except as otherwise provided in Exhibit "D" attached hereto, all
       painting, repairs, alterations and other work expressly required to be
       performed by the landlord under each of the Leases, and all of the other
       obligations of the landlord thereunder which are required to be
       performed prior to Closing (including but not limited to, all tenant
       build-out work) (the "Tenant Work") have been fully performed and paid
       for in full or will be fully performed and paid in full on or before the
       Closing Date and all of the tenants under each of the Leases have
       unconditionally accepted the space they are occupying in the Project.
       All Tenant Work identified on Exhibit "D" as remaining to be completed
       shall either be completed by Seller prior to Closing or Purchaser shall
       be given a credit at Closing for the reasonably estimated expenses of
       completing the Tenant Work.

(f)    The Rent Roll and the updates thereof (including at the time of
       Closing), are and shall be true and correct in all material respects.

(g)    The statements of income and expense for the Project that are to be
       furnished hereunder accurately represent the operations of the Project
       for periods covered thereby and are and will be true and correct in all
       material respects.



                                       6
<PAGE>   74

(h)    Except as otherwise provided in Exhibit "E" attached hereto, Seller
       shall have received no written notices from fire or casualty insurance
       carriers suggesting or requiring physical alterations to the
       Improvements or any of its mechanical, electrical or plumbing systems,
       which have not been corrected.

(i)    Except as otherwise provided in Exhibit "F" attached hereto, there are
       no service, executory or other contracts or collective bargaining
       agreements or employment contracts (either oral or written) with respect
       to the Project which are not cancellable on sixty (60) days' notice (the
       "Contracts") and there are no recorded mechanics' or materialmens' liens
       or claims for such liens affecting the Project or unrecorded mechanics'
       or materialmens' liens or claims for such liens affecting the Project of
       which Seller has received notice. Seller shall terminate all non-union
       employees of the Project, who are not subject to any employment contract
       identified in Exhibit "F", effective on or before Closing unless
       Purchaser requests in writing not less than twenty-one (21) days prior
       to Closing that any of such employees should not be terminated, in which
       event the salaries and other benefits to which such employee(s) are
       entitled shall be prorated at Closing.

(j)    Except as otherwise provided in Exhibit "G" attached hereto, Seller has
       no knowledge nor has received notice of any pending, threatened or
       contemplated condemnation of the Project or any part thereof. The rights
       of the parties with respect to any pending or threatened condemnation
       proceeding identified on Exhibit "G" are governed by Paragraph 13 of
       this Contract.

(k)    In the event that Seller is comprised of a land trust and a beneficiary
       thereof, Seller represents and warrants that the trust is the sole title
       holder of the Project and that all parties executing this Contract on
       behalf of Seller are executing this Contract with full power and 
       authority to execute and cause the consummation of this Contract. In 
       the event that Seller does not include a land trust, but instead is a
       person, partnership or other entity, Seller represents and warrants 
       that it is the sole owner of the Project and is executing this
       Contract with full power and authority to execute and cause the
       consummation of the Contract. In either event, Seller represents,
       warrants and covenants that there shall be no change in the ownership,
       operation or control of Seller from the date hereof to the Closing and
       Seller will not create any easements, liens or other encumbrances with
       respect to the Project.

                                       7
<PAGE>   75

(l)    Seller represents, but does not warrant, that, except as otherwise
       provided in Exhibit "H" attached hereto, Seller has not been advised of
       and is not aware of any defect in the condition of the Project, or any
       portion thereof, which has not been corrected or which will impair the
       operation of the Project. To the best of Seller's knowledge without any
       obligation on the part of Seller to investigate, there is no defect in
       the Real Estate, the Improvements, the structural elements thereof, the
       mechanical systems (including without limitation all heating,
       ventilating, air conditioning, plumbing, electrical, elevator, security,
       utility and sprinkler systems) therein or the roof. To the best of
       Seller's knowledge, the Personal Property is in good operating
       condition.

(m)    To the best of Seller's knowledge, the Project and the use and operation
       thereof are in compliance with all applicable municipal and governmental
       laws, ordinances, regulations, licenses, permits and authorizations and
       there are presently in effect all licenses, permits and other
       authorizations necessary for the use, occupancy and operation of the
       Project as it is presently being operated (the "Governmental
       Approvals").

(n)    Except as otherwise provided in Exhibit "I" attached hereto, there are
       no pending or, to the best of Seller's knowledge, threatened judicial,
       municipal or administrative proceedings affecting the Project or in
       which Seller is or will be a party by reason of Seller's ownership of
       the Project or any portion thereof, including without limitation,
       proceedings for or involving tenant evictions, collections,
       condemnation, eminent domain, alleged building code or zoning violations
       or personal injuries or property damage alleged to have occurred on the
       Project or by reason of the condition or use of the Project. To the
       extent that any proceeding involving personal injury or property damage
       exists or later arises due to an act or omission alleged to have
       occurred prior to Closing, Seller agrees to indemnify, defend and save
       harmless Purchaser from any liability arising therefrom. No attachments,
       execution proceedings, assignments for the benefit of creditors,
       insolvency, bankruptcy, reorganization or other proceedings are pending,
       or to the best of Seller's knowledge, threatened, against Seller, any of
       the entities comprising Seller, nor are any of such proceedings
       contemplated by Seller, or any of the entities comprising Seller.

(o)    Seller represents, but does not warrant, that, except as otherwise
       provided in Exhibit "J" attached hereto, to the best of Seller's
       knowledge without any obligation on the part of Seller to investigate,
       there is no asbestos

                                       8
<PAGE>   76

      or other material of a hazardous, toxic or dangerous nature contained
      within the Project or any component part thereof, including but not
      limited to, any pipes, ducts, paint, tiles or equipment.

(p)   Seller's execution of and performance of this Contract shall not
      constitute a breach of any agreement, understanding, order, judgment or
      decree, written or oral, to which any of the entities constituting Seller
      is a party.

   The continued validity in all respects of all representations and warranties
   set forth in this Contract shall be conditions precedent to Purchaser's
   obligations hereunder, which conditions precedent may be waived in writing
   in whole or in part by Purchaser in its sole discretion. The obligation of
   Purchaser to consummate this Contract and the transactions contemplated
   hereby is further subject to the condition precedent that all
   representations and warranties set forth in this Contract shall be true and
   correct on and as of the Closing with the same force and effect as if made
   at that time. In the event that any representation or warranty is determined
   to be inaccurate on or before the Closing Date, Seller shall take such
   action as is necessary to remedy the situation causing such inaccuracy.
   Seller shall deliver an affidavit or certificate to Purchaser at Closing
   remaking all representations and warranties as of the Closing. With respect
   to Seller's knowledge relating to the representations and warranties
   contained in this Paragraph 7, Seller is under no obligation to
   independently investigate and Seller's failure to independently investigate
   will not impute knowledge to Seller.

8. Covenants of Seller.

   Seller hereby covenants with Purchaser, as follows:

(a)   In the event that after the date hereof, Seller receives notice from any
      governmental body having jurisdiction over the Project of a building code
      or other violation, it shall immediately notify Purchaser, send a copy of
      such notice to Purchaser, Seller shall promptly commence to repair and
      cure such violation and prosecute the repairs to the Closing with due
      diligence or otherwise commence to remove such violation of record with
      due diligence. In the event such repairs (if necessary) are not completed
      prior to the Closing Date, Seller shall furnish to Purchaser at the
      Closing, proof of payment for the repairs theretofore made and shall
      credit Purchaser with a closing adjustment equal to the amount necessary
      to complete the repairs pursuant to the terms of the contract entered
      into for such repair work. Such contract shall be entered into with a
      reputable contractor unaffiliated with Seller and provide for

                                       9
<PAGE>   77

      compensation at no greater than reasonably prevailing market rates for
      the area in which the Project is located. Such contract shall be assigned
      to Purchaser at Closing. Notwithstanding the foregoing, if the building
      code or other violation results in a cost to Seller in excess of
      $400,000.00, Seller may, within fifteen (15) days after receipt of such
      notice from a governmental body, give notice to Purchaser of its intent
      to terminate this Contract, subject to Purchaser's right to prevent any
      such termination by giving notice to Seller, within ten (10) days after
      its receipt of Seller's notice, agreeing to pay all such costs in excess
      of $400,000.00, in which event, this Contract shall remain in full force
      and effect. In the event that Purchaser fails to so notify Seller, this
      Contract shall terminate, in which event the Earnest Money shall be
      returned to Purchaser, and neither party shall have any further liability
      to the other, except that Seller shall be liable to Purchaser for
      Purchaser's actual out-of-pocket expenses incurred in connection with this
      Contract and the Feasibility Period.

(b)   In addition to, but not in limitation or derogation of the above, Seller
      shall execute and deliver to Purchaser at Closing an assignment or
      assignments assigning to Purchaser all existing assignable guarantees and
      warranties issued or made in connection with the construction,
      improvement, alteration and repair of any improvements or personal
      property comprising a part of the Project, together with the original of
      each such guaranty and warranty in Seller's possession, if any.

(c)   Prior to Closing and except as otherwise provided herein, unless Seller
      obtains the prior written consent of Purchaser, which consent shall not
      be unreasonably withheld or delayed, Seller shall neither execute any new
      lease nor renew or modify any existing Lease. Withholding of consent by
      Purchaser shall be deemed to be reasonable if the terms of any proposed
      new lease or renewal or modification of any existing Lease do not comport
      with current rental market standards in Oak Brook, Illinois. Subject to
      the foregoing, Seller shall use reasonable efforts to obtain tenants for
      all space which is now vacant or which will become vacant prior to the
      end of the month following the Closing. Seller shall use its best efforts
      to obtain renewals of existing Leases which expire prior to closing.
      Without the prior written consent of Purchaser, which shall not be
      unreasonably withheld, Seller shall not terminate any of the Leases,
      unless the tenant thereunder shall have materially defaulted. Seller
      shall not accept from any of the tenants payment of rent more than one
      month in advance or apply any security deposit to rent due from any
      tenant. At Closing the security deposit provided for

                                       10
<PAGE>   78

      under each of the Leases and all interest accrued thereon, if any, shall
      be fully assigned to Purchaser.

(d)   Prior to Closing, Seller shall not enter into any contract with respect
      to the Project which will survive the Closing or otherwise affect the
      use, operation or enjoyment of the Project after the Closing. Further,
      Seller will deliver to Purchaser copies of any notices it receives from
      the DuPage County, Illinois Assessor's Office with respect to a change in
      the assessed valuation of the Real Estate and Improvements.

(e)   The existing insurance policies pertaining to the Project shall remain
      continuously in force to the Closing Date.

(f)   Seller shall operate and manage the Project in a first class manner,
      maintaining present services (including pest control), and shall
      maintain the Project in good repair and working order (including such
      replacements as may be required), shall keep on hand sufficient
      materials, supplies, equipment and other personal property for the
      efficient operation and management of the Project in a first class
      manner, and shall perform when due all of Seller's obligations under the
      Leases, Contracts, Governmental Approvals and other agreements relating
      to the Project and otherwise in accordance with applicable laws,
      ordinances, rules and regulations affecting the Project. Except as
      otherwise provided herein, Seller shall deliver the Project at Closing in
      substantially the same condition as it is on the date hereof, reasonable
      wear and tear excepted, and shall terminate the Contracts, effective as
      of the Closing Date, except those of the Contracts designated in writing
      by Purchaser prior to Closing.  None of the Personal Property or fixtures
      shall be removed from the Project, unless replaced by personal property
      or fixtures of equal or greater utility and value.

(g)   In the event that any Lease terminates prior to Closing, Seller shall
      consult with Purchaser as to the extent of enforcement of any
      requirements in the Lease with respect to the condition of the leased
      premises upon surrender of the leased premises. All debris shall be
      removed from any vacant space.

(h)   Except for brokerage or leasing commissions for Leases entered into after
      the date hereof, Seller has paid or will pay in full, prior to Closing,

      kind relating to the Project and utility charges, relating to the period
      prior to Closing. Except as provided elsewhere in this Contract, any

<PAGE>   79
      
      Tenant Work and other work required to be performed under the Leases or
      other agreements affecting the Project have been or will by the Closing
      be completed and paid for in full. Any brokerage fee or similar

(i)   All action required pursuant to this Contract which is necessary to

      otherwise provided herein.

(k)   From and after the date hereof through Closing, Seller agrees to furnish
      to Purchaser monthly, upon preparation thereof, updated rent rolls and

   shall not be merged into any deed or other instrument of conveyance
   delivered at Closing.

9. Conditions Precedent to Closing.

   The following shall be conditions precedent to Purchaser's obligation to
   close hereunder (the "Conditions Precedent"), which Conditions Precedent may
   be waived in writing by Purchaser in its sole discretion in whole or in
   part:

(a)   The physical condition of the Project shall be substantially the same on
      the Closing Date as on the date hereof, reasonable wear and tear
      excepted, unless the alteration of said physical condition is the result
      of a Casualty (as defined herein).

(b)   At Closing, there shall be no administrative agency, litigation or
      governmental proceeding of any kind whatsoever, pending or threatened,
      which, if not bonded over to Purchaser's reasonable satisfaction prior to
      Closing, after Closing would in Purchaser's sole, reasonable discretion
      adversely affect the value of the Project, or the ability of Purchaser to
      operate the Project in the manner it is being operated on the date
      hereof.

(c)   On the Closing Date, no proceedings shall be pending or threatened which
      could or would involve the change,

                                       12
<PAGE>   80
      
      redesignation, redefinition or other modification of the zoning
      classification of (or any building or environmental code requirements
      applicable to) the Project, or any portion thereof.

(d)   As of the Closing Date, the warranties, representations and covenants of
      Seller hereunder shall be true and correct and Seller shall have
      performed all of its covenants and obligations hereunder.

(e)   As of the Closing Date, the information set forth on the exhibits
      attached hereto is true and correct.

10. Prorations and Adjustments.

    The following shall be prorated and adjusted between Seller and Purchaser
    as of the Closing Date, except as otherwise specified:

(a)   Mortgage principal balance and accrued and unpaid interest (in the event
      Purchaser takes title to the Project subject to Seller's existing first
      mortgage as provided in this Contract), rents and other charges collected
      by Seller for the month of Closing (and succeeding months), security
      deposits, prepaid service contracts, maintenance and operating employees'
      wages, maintenance and operating employees' accrued rights, if any, under
      union contracts to paid vacations, general real estate taxes, special
      assessments, and other similar items shall be adjusted ratably as of the
      Closing. General real estate taxes shall be prorated on the basis of the
      last ascertainable tax bill, but shall be reprorated when the actual tax
      bills therefor issue. Seller shall be entitled to all tax refunds, if
      any, obtained on account of taxes paid for the years preceding the
      Closing, and a prorata portion of tax refunds for the year of Closing,
      less the amount, if any, of Seller's prorata share of such funds expended
      by Purchaser in obtaining such refunds. Purchaser shall receive credit
      for advance rents beyond the then current month and for security deposits
      under the Leases. None of the security deposits may be applied by Seller
      to delinquent rents. There shall be no proration credit to Seller for
      delinquent rents and other charges (the "Delinquent Rents"), except that
      rents that are not more than thirty (30) days delinquent that are due
      from tenants who are not more than thirty (30) days delinquent in the
      payment of rent shall be prorated, but settlement between the parties
      shall be made only when such amounts have actually been collected. After
      Closing, Seller shall not take any action against any tenant owing
      Delinquent Rents. For a period of thirty (30) days after Closing,
      Purchaser shall use reasonable efforts to collect Delinquent Rents but
      such undertaking shall not


                                       13
<PAGE>   81

      be deemed to obligate Purchaser to expend any funds or institute legal
      proceedings of any kind. Rents and other amounts received by Purchaser
      after Closing from a tenant owing Delinquent Rents shall be applied (i)
      first, to all of Purchaser's costs of collection incurred with respect to
      such tenant (including reasonable attorneys' fees), (ii) second, to rents
      due for the month in which such payment is received by Purchaser, (iii)
      third, to rents attributable to any period after Closing which are past
      due on the date of receipt, and (v) then to Delinquent Rents. Seller
      shall promptly remit to Purchaser and account for all sums received by
      Seller from tenants after Closing and Purchaser shall promptly remit to
      Seller and account for all sums received by Purchaser from tenants after
      closing which, pursuant to this subparagraph, are to be applied to
      Delinquent Rents or are otherwise to be paid to Seller. All percentage
      rents and additional rents, if any, payable under any of the Leases,
      shall be prorated as of the Closing based on respective periods of
      ownership during the lease year covered thereby, but reprorated and paid
      when and as received.

(b)   In lieu of prorating electricity, gas, water and other public utilities
      due to the utility companies, Seller shall arrange for the rendition of
      final bills as of the Closing Date or as near as possible thereto by the
      respective utility companies, and Seller shall pay such bills as and when
      rendered. As to charges to tenants for such public utilities, Seller
      shall also arrange for the rendition of bills to tenants as of the
      Closing Date or as near as possible thereto, and Seller shall be 
      entitled to remittances from Purchaser of such charges as and when 
      collected from tenants in accordance with the provisions of subparagraph 
      (a) above. In any event, all master meters and submeters shall be read 
      within a period of three consecutive days.

(c)   The Project shall be operated for the benefit of Seller until the Closing
      Date. After Closing, the Project shall be operated for the benefit of
      Purchaser. Solely for purposes of the prorations to be made hereunder the
      Closing shall be deemed to occur at 11:59 p.m. on the day prior to the
      Closing Date. All such prorations shall be made on the basis of the
      actual number of days elapsed as of the Closing Date. Bills received
      after Closing which relate to expenses incurred prior to Closing or
      services performed at the direction of Seller prior to Closing shall be
      paid by Seller.

11. Escrow.

    This transaction shall be closed through an escrow (the "Escrow") with the
    Title Insurer, in accordance with the general provisions of the usual form
    
                                       14

    of the deed and other documents to be delivered hereunder shall be made
    through the Escrow. The cost of the Escrow shall be divided equally between
    Seller and Purchaser.  Purchaser shall be solely responsible for the cost
    of any money lender's escrow required by its lender, if any, in connection
    with the Closing. The attorneys for Seller and Purchaser are authorized to
    execute the escrow agreement, any amendments thereto and all directions or
    communications thereunder. The escrow agreement shall be auxiliary to this
    Contract and the terms and provisions hereof shall be controlling as
    between the parties hereto. The escrow agreement shall be executed by the
    parties within fifteen (15) days from the date hereof and upon creation of
    the Escrow, the Earnest Money shall be immediately deposited therein. At
    Closing, the Earnest Money shall be returned to Purchaser.

13. Eminent Domain.

    In the event that, prior to Closing, any eminent domain proceeding
    affecting the Project is commenced or threatened by a governmental body
    having the power of eminent domain, Seller shall immediately give Purchaser
    written notice thereof. If the proceeding affects or will affect portions
    of the Project, the loss of which would not adversely affect the use
    thereof or result in a diminution of value of the Project of more than
    $50,000.00, then the Closing shall take place as provided in this Contract
    and at Closing Seller shall assign to Purchaser all right, title and
    interest with respect to such proceeding and awards, damages or other
    compensation arising from such proceeding. If the proceeding affects or
    will affect portions of the Project, the loss of which would adversely
    affect the use thereof or result in a diminution of value of the Project of
    more than $50,000,00 then Purchaser may elect by written notice to Seller
    to (i) terminate this Contract in its entirety, by written notice to
    Seller, in which event the Earnest Money shall be returned immediately to
    Purchaser and neither party will have any further liability to the other
    hereunder or (ii) proceed to close the purchase of the Project, in which
    event Seller shall assign to Purchaser at Closing all of Seller's right,
    title and interest with respect to such proceeding. Unless or until this
    Contract is terminated in its entirety pursuant to this Paragraph 13 or
    otherwise, Seller shall take no action with respect to any pending or
    threatened eminent domain proceeding without the prior written consent of
    Purchaser.

14. Insurance, Risk of Loss.

    At all times prior to Closing, Seller shall maintain the existing casualty
    and liability insurance on the Project in full force and effect. Prior to
    the Closing Date, and not withstanding the pendency of this Contract, the
    entire risk of loss or damage to the Project by fire or other casualty is
    borne and assumed by Seller, except as otherwise provided in this Paragraph
    14. If all or a portion of the Project is destroyed or damaged by one or
    more fires, windstorms, hurricanes, hailstorms, floods, explosions,
    earthquakes, sinkholes or other casualties (collectively, the "Casualties")
    prior to Closing, Seller shall give Purchaser prompt notice thereof. In the
    event one or more Casualties shall occur prior to Closing, then the
    following provisions shall apply:

(a)   If the reasonably estimated cost of restoration of the Project is less
      than $100,000.00, Seller shall use its best efforts to restore, prior to
      Closing, the Project to its previous condition.  If Seller is unable to
      complete said restoration prior to Closing, Purchaser shall be entitled
      to elect by written notice to Seller prior to Closing either (i) to
      receive a proration credit

                                       19
<PAGE>   87
      against the cash due at Closing for the cost of restoration to be
      incurred by Purchaser (notwithstanding anything to the contrary in
      Paragraph 10 above), or (ii) to accept an assignment from Seller to
      Purchaser of all of Seller's rights with respect to all insurance
      proceeds receivable in respect of such Casualties and to receive a
      proration credit against the cash due at Closing equal to all deductibles
      therefrom (notwithstanding anything to the contrary in Paragraph 10
      above). In the event Purchaser elects the option set forth in clause (i)
      of the preceding sentence, Seller shall be entitled to retain all
      insurance proceeds with respect to such Casualties.

(b)   If the reasonably estimated cost of restoration of the Project is
      $100,000.00 or more, Seller shall promptly take such action as is
      required to secure the damaged portion of the Project and protect it from
      further damage and promptly file all appropriate claims under its
      insurance policies and in good faith negotiate the highest possible
      settlement amount from the insurers. Purchaser shall have the right to
      participate in the adjustment of the claim. Seller shall notify Purchaser
      promptly in writing of the settlement amount which Seller proposes to
      accept. At any time prior to fifteen (15) days following receipt of such
      notice, Purchaser may elect in a written notice to Seller (it being
      understood that Purchaser may make the following election prior to the
      receipt of Seller's notice) either:

              (i)   to proceed with the Closing, in which event, the insurance
                    proceeds shall be assigned to Purchaser at Closing (with
                    any proceeds paid to Seller prior to Closing to be credited
                    to Purchaser) and Purchaser shall receive a proration
                    credit against the cash due at Closing equal to all
                    deductibles therefrom (notwithstanding anything to the
                    contrary in Paragraph 10 above); or

             (ii)   to terminate this Contract by written notice to Seller, in
                    which event the Earnest Money shall be returned to
                    Purchaser, and neither party shall have any further
                    liability to the other hereunder.

    The date set for Closing shall be extended, if necessary, to accommodate
    the notice periods provided for in this Paragraph 14.  All restoration work
    performed pursuant to this Paragraph 14 shall be performed using first
    class materials and highest quality workmanship. Purchaser shall have the
    right to inspect the work performed by or at the direction of Seller. If
    the Project has not been fully restored by the time the Closing occurs,
    Purchaser shall receive a proration

                                       20
<PAGE>   88
    credit at Closing (notwithstanding anything to the contrary in Paragraph 10
    above) for all rents abated by reason of said casualty and which otherwise
    would have been due with respect to the period between the Closing Date and
    the estimated date of completion of the work.

15. Broker's Commission.

    If the sale is consummated and the Purchase Price paid to Seller, Seller
    agrees to pay a real estate sales commission of four (4%) percent of the
    Purchase Price as follows: two (2%) percent to Irvine Associates Inc. and
    two (2%) percent to LaSalle Mortgage and Realty Company, Inc. (the
    "Brokers"), the only real estate brokers involved in this transaction. Each
    of the parties represents and warrants to the other that it has not
    incurred and will not incur any other liability for brokerage fees or
    commissions in connection with this Contract. It is agreed that if any
    claims for brokerage fees or commissions are ever made against Seller or
    Purchaser in connection with this transaction, all such claims shall be
    handled and paid by the party (the "Committing Party") whose actions or
    alleged commitments form the basis of such claim. The Committing Party
    further agrees to indemnify and hold the other harmless from and against
    any and all such claims or demands with respect to any brokerage fees or
    commissions or other compensation asserted by any person, firm, or
    corporation other than the Brokers, in connection with this Contract or the
    transaction contemplated hereby.

16. Survival.

    The terms, provisions, representations, warranties and covenants made
    herein shall be continuing and shall survive for a period of one year from
    the date of Closing and shall not merge into the Closing or the delivery of
    deeds and other instruments of conveyance; provided, however, that the
    obligation of either party contained in Paragraphs 7(c), 8(h) and 15 of
    this Contract to indemnify, defend and save harmless the other party from
    liabilities arising from events occurring or alleged to have occurred prior
    to Closing shall not be subject to the one-year limitation set forth
    herein.

17. Default.

(a)   In addition to the specific rights of Purchaser to terminate this
      Contract as provided in Paragraph 6(d) hereof and other rights incidental
      thereto, if any of Seller's representations and warranties contained
      herein shall not be true and correct, or if Seller failed to perform in
      any material respect any of the covenants and agreements contained herein
      to be performed by Seller within the time for performance as specified
      herein

                                       21
<PAGE>   89

      (including Seller's obligation to close), Purchaser may elect to (i)
      terminate Purchaser's obligations under this Contract by written notice
      to Seller, in which event the Earnest Money shall be returned immediately
      to Purchaser, or (ii) close, in which event Purchaser may file an action
      for specific performance of this Contract to compel Seller to close the
      transactions contemplated by this Contract and/or cure such default, in
      whole or in part, in which event Purchaser shall be entitled to deduct
      from the Purchase Price the cost of such action and/or the actual or
      reasonably anticipated cost to cure such defects as well as any and all
      reasonable expenses incurred by Purchaser in connection therewith
      including attorneys' fees, provided such deduction does not exceed
      $100,000.00; or (iii) refuse to close by written notice to Seller, in
      which event the Earnest Money shall be returned immediately to Purchaser,
      and Purchaser shall be entitled to pursue all available rights and
      remedies at law or equity against Seller, provided, however, that
      Seller's liability to Purchaser for damages at law shall not exceed
      $100,000.00. The remedies of Purchaser set forth in this Paragraph 17(a)
      shall be in addition to remedies otherwise applicable or provided in this
      Contract, it being understood that Purchaser's rights and remedies under
      this Contract shall be non-exclusive and cumulative and that the exercise
      of one remedy or form of relief available to Purchaser hereunder shall
      not be exclusive or constitute a waiver of any other, except that
      Seller's total liability for damages shall not exceed $100,000.00. No
      act, event, or state of facts, whether constituting a default or event of
      default under the GIS Lease or not shall be available to Seller as a
      defense to any remedy sought by Purchaser pursuant to this Section 17.

(b)   In the event Purchaser defaults in its obligation to close the purchase
      of the Project for any reason, the Earnest Money shall be delivered to
      Seller, the amount thereof being liquidated damages, it being understood
      that Seller's actual damages in the event of such default are not capable
      of precise determination and that the forfeiture of the Earnest Money
      shall be Seller's sole and exclusive remedy for Purchaser's default.

(c)   Anything contained herein to the contrary notwithstanding, if any party
      hereto fails to perform any obligation hereunder, or violates the terms
      of this Contract, such party shall be entitled to receive notice of such
      default and shall be entitled to five (5) days from the date of such
      notice in which to cure such default specified.  The Closing Date shall
      be extended accordingly.

18. Existing First Mortgage.

    In the event that the existing first mortgage encumbering the Project (the
    "Mortgage") cannot, by its terms, be prepaid by Seller at Closing,
    Purchaser hereby agrees to take title to the Project subject to the lien of
    the Mortgage; provided, however, that (i) Purchaser shall not assume any
    liability under the Mortgage or the note (the "Note") secured by the
    Mortgage; (ii) any penalties, premiums, fees or charges imposed with
    respect to the conveyance of the Project to Purchaser subject to the lien
    of the Mortgage shall be paid by Seller; and (iii) any consent required
    with respect to the conveyance of the Project to Purchaser subject to the
    lien of the Mortgage shall be obtained by Seller. Seller shall provide
    Purchaser with a true and complete copy of the Note at least ten (10) days
    prior to Closing and Seller shall certify to Purchaser in writing as to the
    truth and accuracy of such copy of the Note. In the event that this
    Paragraph 18 is in effect, it shall be a Condition Precedent to Purchaser's
    obligation to close hereunder, which Condition Precedent may be waived in
    writing by Purchaser in its sole discretion in whole or in part, that
    Seller shall deliver to Purchaser at Closing, in addition to the other
    documents to be delivered to Purchaser hereunder an estoppel letter or
    statement from the holder of the Note (a) stating the unpaid principal
    balance of the Note; (b) stating the date through which interest has been
    paid; (c) stating the existence and amount of any escrows and reserve
    accounts; (d) stating that no uncured default exists under the terms of the
    Note and Mortgage; (e) consenting to the conveyance of the Project to
    Purchaser subject to the lien of the Mortgage; and (f) agreeing to accept
    payments due under the Note from Purchaser and to give notice of any
    defaults under the Note or Mortgage (or any related documents) to
    Purchaser.

19. Notices.

    All notices required or desired to be given hereunder shall be in writing
    and shall be delivered personally, by a nationally recognized air courier
    or by certified or registered mail and, shall be deemed given when
    personally delivered, the day following delivery to a nationally recognized

20. Successors and Assigns.

    The terms, conditions and covenants of this Agreement shall be binding upon
    and shall inure to the benefit of the parties and their respective
    nominees, successors, beneficiaries and assigns; provided, however, no
    conveyance, assignment or transfer of any interest whatsoever of, in or to
    the Project or of this Contract shall be made by Seller during the term of
    this Contract.  Purchaser may assign all or any of its right, title and

    Purchaser, the assignee shall be deemed to be the Purchaser hereunder for
    all purposes hereof and have all rights of Purchaser hereunder and the
    assignor shall be released from all liability hereunder, but such
    assignment shall not affect the remedy of Seller under Paragraph 17(b).

21. Miscellaneous.

(a)   This Contract constitutes the entire understanding between the parties
      with respect to the transaction contemplated herein, and all prior or
      contemporaneous oral agreements, understandings, representations and
      statements, and all prior written agreements, understandings,

<PAGE>   92
      representations and statements are merged into this Contract.  Neither
      this Contract nor any provisions hereof may be waived, modified, amended,
      discharged or terminated except by an instrument in writing signed by the

      amendment, discharge or termination is sought, and then only to the
      extent set forth in such instrument.

(b)   The obligations of Purchaser to make the payments to close the
      transaction described herein are subject to the express conditions
      precedent set forth in this Contract (the "Conditions Precedent"), each
      of which is for the sole benefit of Purchaser and may be waived at any
      time by written notice thereof from Purchaser to Seller. The waiver of
      any particular Condition Precedent shall not constitute the waiver of any
      other.

(c)   Relative to each representation and warranty made by Seller in this
      Contract, Seller shall make reasonable inquiries as to the accuracy
      thereof to its employees, managers, agents and other appropriate parties
      and the actual on constructive knowledge of such parties will be imputed
      to Seller.

(d)   This Contract shall not be construed more strictly against one party than
      against the other merely by virtue of the fact that it may have been
      prepared by the attorney for one of the parties. The headings of various
      paragraphs in this Contract are for convenience only, and are not to be
      utilized in construing the content or meaning of the substantive
      provisions hereof.

      not unreasonably interfere with other tenants' use of their demised
      premises.

IN WITNESS WHEREOF, the parties have executed this Contract as of the day and

             EXHIBIT A FOR THE REAFFIRMATION OF GUARANTEE AGREEMENT

<PAGE>   110
                           LEASE AMENDMENT AGREEMENT

     THIS LEASE AMENDMENT AGREEMENT ("Agreement") is made in Oak Brook,
Illinois, as of this 1st day of August, 1990, by and between The Aetna Casualty
and Surety Company, a Connecticut corporation ("Landlord"), and GIS Information
Systems, Inc., an Illinois corporation ("Tenant").

     WHEREAS, Tenant is currently the lessee under a lease dated as of June 10,
1987 ("Lease"), between Tenant, as lessee, and LaSalle National Bank, not
personally, but as trustee U/T/A #107194 and 815 Commerce Drive REIP, an
Illinois limited partnership, a beneficiary of said trust, as landlord
(collectively the "Former Landlord") for certain commercial space located at
815 Commerce Drive, Oak Brook, Illinois (the "Property"), a copy of which is
attached hereto as Exhibit A;

     WHEREAS, Tenant formerly leased certain additional space totalling
approximately 2,775 square feet and commonly known as Suite 106 ("Suite 106")
at the Property, pursuant to a lease dated November 3, 1989 (a copy of which is
attached as Exhibit B) which is now expired and which Tenant continues to lease
on a month-to-month basis;

     WHEREAS, Tenant wishes to lease Suite 106 for an additional term and, in
addition, wishes to lease approximately 5200 additional square feet of space at
the Property;

     WHEREAS, Landlord is the new owner of the Property and has succeeded to
the Former Landlord's rights under the Lease;

     WHEREAS, Landlord and Tenant each agree to waive any rights relating to
any non-compliance by the other with the terms of the Lease as of the date of
this Agreement;

     WHEREAS, Landlord and Tenant wish to amend the Lease;

     NOW, THEREFORE, for good and valuable consideration, the receipt and
sufficiency of which are hereby acknowledged, Landlord and Tenant agree as
follows:

     1.  Incorporation of Recitals. The foregoing recitals are hereby
incorporated into this Agreement.

<PAGE>   111

     2.  Additional Rental Space. Landlord hereby leases to Tenant for a term
beginning on August 1, 1990 and continuing to and including August 31, 2002,
the following space:

        a.  Suite 106 as further described in Exhibit B attached hereto; and

        b.  Approximately 5,200 square feet of space, the exact square footage
            and location of which are set forth in Exhibit C attached hereto.

Collectively, a and b above shall be referred to herein as the "Additional
Rental Space."

     3.  Rent and Additional Rent. Subject to the exceptions stated in
paragraphs 5 and 6 below, Tenant shall pay base rent ("Rent") and its pro rata
share of additional rent as that term is defined in the Lease ("Additional
Rent"): for the Additional Rental Space. Rent shall be as set forth in the
Schedule in Exhibit D attached hereto. The Tenant's pro rata share (or
percentage) of Additional Rent shall be equal to the square footage of the
Additional Rental Space, as determined after final measurement, divided by
63,156, the total rental area of the Property.  (For example, if the Additional
Rental Space is determined to be 8,000 square feet, the Tenant's pro rata share
of Additional Rent for the Additional Rental Space shall be 8,000 divided by
63,196.)

     4. Tenant Improvements. Landlord shall build out tenant improvements
("Tenant Improvements") for the Additional Rental Space in accordance with the
plans and specifications set forth in Exhibit E. Landlord shall pay (or
reimburse Tenant) for the actual cost of the Tenant Improvements up to $16.00 
per square foot. If the Tenant Improvements cost less than $16.00 per square 
foot, the Tenant shall be entitled to have the difference credited against its
Rent.

     5.  Rent: During Construction. From the date of this Agreement up to the
time when the Tenant Improvements are substantially completed, the Tenant shall
pay no Rent, no Additional Rent, and no other rent of any kind for that portion
of the Additional Rental Space described in paragraph 2(b) hereof. However,
during that same period, the Tenant shall pay the Landlord rent for Suite
106 at the same rate as formerly provided for in Exhibit B.

     6.  Rental Abatement After Construction. Tenant shall be entitled to an
abatement of Rent for the entire Additional Rental Space during the first
fifteen months after the Tenant Improvements are substantially completed. During
this

                                       2
<PAGE>   112

fifteen month period, Tenant shall be obligated to pay only Additional Rent for
the Additional Rental Space.

     7. Amendment to Lease. The following paragraphs of the Lease (which are
located in that portion of the Lease entitled "Addendum to Lease") are hereby
deleted and of no further legal force or effect: Sections A-11, A-12, A-13, 
A-14, A-15 and A-16.

     8.  Tenant's Right to Lease Extra Space.

         (a)  Tenant shall have the right at any time and upon thirty (30)
     days' written notice to Landlord to lease approximately 3,000 square feet
     of additional space located immediately west of the former Madison Pizza
     space on the first floor of the Property (as more specifically described
     in Exhibit F attached hereto) (the "Extra Space"), provided such Extra
     Space is not then under lease to another person.

         (b)  Landlord shall not lease the Extra Space or any part thereof to
     any person other than Tenant without first giving Tenant thirty days'
     written notice of Landlord's intention to do so and the opportunity to
     lease the Extra Space itself. At any time during the thirty days after its
     receipt of such notice, Tenant may exercise its right to lease the Extra
     Space by notifying Landlord in writing of its intention to do so.

         (c)  If Tenant advises Landlord that it does not wish to lease the
     Extra Space or fails to advise Landlord of its intention to lease the
     Extra Space within the thirty-day period, the Landlord may lease the Extra
     Space to the person identified in the Landlord's notice (or to an entity
     related to such person).  However, if for any reason the Landlord does not
     enter into a lease with such person (or an entity related to such person)
     within one hundred eighty (180) days of the date of the Landlord's notice,
     the proposed lease and the Landlord's notice shall be deemed a nullity and
     the Landlord shall comply with subparagraph (b) of this paragraph 8 before
     leasing the Extra Space to any person.

         (d)  If Tenant exercises its right to lease the Extra Space, then
     Landlord and Tenant, as soon as is practicable thereafter, shall enter
     into a lease agreement for the Extra Space. The terms and conditions of
     such lease agreement ("Extra Space Lease Agreement") shall be as follows:

         Effective Date: As soon as practicable with an allowance of up to 60
         days for

                                       3
<PAGE>   113
         construction work and/or tenant improvements to be substantially
         completed and the space ready for occupancy.

         Initial Team: From commencement date until August 31, 2002.

         Rent: To begin upon occupancy or upon the substantial completion of
         tenant improvements, whichever is sooner. To be the same (per square
         foot) as the Rent payable on the Additional Rental Space determined as
         of the effective date of the Extra Space Lease Agreement and with the
         same increases thereafter, all in accordance with Exhibit D hereto.

         Additional Rent: Tenant shall pay its pro rata share of Additional
         Rent for the Extra Space.

         Rental Abatement: Tenant shall be entitled to an abatement of Rent
         which, in total, shall equal 1 1/4 months for each full year of the
         term of the Extra Space Lease Agreement (measured from the
         commencement date thereof to August 31, 2002). The abatement shall
         begin upon occupancy or upon the substantial completion of tenant
         improvements, whichever is sooner.

         Build-Out Allowance: To be determined in accordance with Section A-17
         of the Lease.

         Other Terms: Except to the extent it is inconsistent with the terms
         stated above, the Lease shall govern the Landlord's and Tenant's
         rights and obligations with respect to the Extra Space.

         (e)  So long as Tenant is not in default under the Lease as amended
     herein (or said default is not in the process of being cured within any
     applicable cure periods), the Tenant's right to lease the Extra Space
     shall be a continuing right; i.e., if the Extra Space is leased to a
     person other than Tenant, Tenant shall once again have the right to lease
     the Extra Space on the terms stated in this paragraph 7 upon the
     termination or expiration of such other person's lease.

                                       4
<PAGE>   114

     9.  Tenant's Right of First Refusal on the Sale of the Property.  Tenant's
right of first refusal upon sale of the property as set forth in Section A-27
of the Lease is hereby amended to read as follows:

     In addition to the option granted to Tenant in Section A-7 hereof, Tenant
has the following rights:

     In the event that Landlord negotiates and accepts a signed letter of
intent to purchase the Property from an unrelated party or receives an offer to
purchase the Property which Landlord wishes to accept, Landlord shall notify
Tenant of such facts in writing and shall include in such notice a description
of the relevant terms of the proposed transaction, including price and
financing, as well as a copy of any and all documents constituting the letter
of intent or offer. Tenant has 30 days from receipt of such notice to exercise
this right of first refusal to purchase the Property on the same terms and
conditions as set forth in the notice, by so advising the Landlord in writing.
If Landlord and the same proposed purchaser (which includes any assignee of or
entity related to purchaser) change the conditions of the offer for purchase or
sale by reducing the sales price greater than 5%, or if the purchase money
financing offered by seller is increased by more than 5%, or if the percentage
of interest seller is to charge on such financing is adjusted by more than 1%
(100 basis points) downward, Landlord shall give a new written notice to Tenant
with the changed terms and Tenant has 15 calendar days to respond in writing.
No other changes in the terms of the purchase or sale shall require Landlord to
give additional notice to Tenant. In each case, if Tenant fails to respond by
the required reply date, Tenant shall be deemed as to have waived this right of
first refusal. If the purchaser (or a related entity) identified in any
relevant notice from Landlord does not actually close on the Property within
one year after the date of the Landlord's notice to Tenant, the Landlord's
notice and the proposed transaction shall be deemed null and void and Landlord
again shall comply with the terms of this paragraph before selling the Property
to any person.

     The new terms of this Amended Section A-27 shall pertain to the pending
sales transaction pursuant to a Letter of Intent dated June 20, 1990 from
Landlord to Thomas J. McCracken.

     10. Lease Remains in Effect. The Lease (including the Addendum thereof),
as expressly modified herein, shall remain in full force and effect. In
addition, except to the extent that its terms are inconsistent with the terms
of this Agreement, the Lease shall govern the rights and obligations of the
Landlord and Tenant with respect to the Additional Rental Space. In particular
and without limiting the

                                       5
<PAGE>   115

generality of the foregoing, Sections A-6, A-21, and A-22 shall apply to this
Agreement.

     11.  Hazardous Waste. Tenant agrees not to store or dispose of any toxic
or hazardous materials on the Premises and Additional Space at anytime without
the prior written consent of Landlord.

     12.  Notice. Any notice sent under the Lease or this Agreement shall be
sent by certified or registered mail and shall be addressed as follows:

or to such other persons or such other addresses designated by Landlord or
Tenant in writing.

     13.  Cross-Default Provision. A default by Landlord or Tenant in any of
the terms and conditions of the Lease (as modified by the provisions herein)
shall constitute a default by such party under this Agreement and vice versa.

     14.  Assignment. All rights and obligations of Landlord and Tenant
hereunder shall inure to the benefit of their respective successors and
assigns.

     15.  Applicable Law. This Agreement shall be interpreted and governed by
