THE COMPANY

The Company is a self-administered and self-managed real estate investment
trust (a "REIT") that began operations through a related entity in 1972. At June
30, 1997, the Company owned a diversified portfolio of 262 in-service
industrial, office and retail properties (the "Properties"), encompassing
approximately 31.4 million square feet located in seven states, and 26 buildings
and one building expansion encompassing approximately 4.1 million square feet
under development. The Company also owned approximately 1,300 acres of
unencumbered land (the "Land") for future development, of which approximately
75% is zoned for industrial use and which is typically located adjacent to the
Properties. The Company provides leasing, management, construction, development
and other tenant-related services for the Properties and certain properties
owned by third parties. The Company has the largest commercial real estate
operations in Indianapolis and Cincinnati and is one of the largest real estate
companies in the Midwest. The Company believes that the Midwest offers a
relatively strong and stable economy compared to other regions of the United
States and provides significant growth potential due to its central location,
established manufacturing base, skilled work force and moderate labor costs.

The Company has developed over 50 million square feet of commercial property
since its founding including an average of approximately 4.1 million square feet
per year during the last five years. In addition, the Company acquired
approximately 8.9 million square feet during the three years ended December 31,
1996. During the six months ended June 30, 1997, the Company placed in service
2.6 million square feet of new development and acquired 1.8 million square feet
of property.

The Company manages over 43 million square feet of property, including over
8.1 million square feet owned by third parties. The Company manages
approximately 35% and 29% of all competitive suburban office, warehousing and
light manufacturing space in Indianapolis and Cincinnati, respectively. In
addition to providing services to approximately 1,800 tenants in the Properties,
the Company provides such services to over 900 tenants in 92 properties owned by
third parties. Based on market data maintained by the Company, the Company
believes that it was responsible in the first six months of 1997 for
approximately 67% and 34% of the net absorption (gross space leased minus lease
terminations and expirations) of competitive suburban office, warehousing and
light manufacturing space in Indianapolis and Cincinnati, respectively. The
Company believes that its dominant position in the primary markets in which it
operates gives it a competitive advantage in its real estate activities.

information as compared to the same period in 1996.

</TABLE>

On July 24, 1997, the Company's Board of Directors raised its regular
quarterly common dividend from $.51 per share to $.59 per share, payable on
August 29, 1997 to common shareholders of record on August 15, 1997. The new
dividend is an increase of $.32 per year which is a 15.7% increase over the
previous amount. This dividend equals $2.36 on an annualized basis. The Board of
Directors also declared a two-for-one split of the Company's common stock (the
"Stock Split") to be effected as a 100% share dividend, payable on August 25,
1997 to common shareholders of record on August 18, 1997. The Company also
announced that its Board of Directors anticipates the Company's regular
quarterly dividend amount to be $.30 per common share on a post-Stock Split
basis. This would equate to a dividend increase of 1.7% and follows the
Company's 15.7% dividend increase announced July 24, 1997. The official
declaration for this new dividend is expected to be on October 23, 1997, the
date of the Company's next regularly scheduled Board of Directors' meeting.
Share and per share amounts in this Prospectus Supplement have been restated to
reflect the effect of the Stock Split.

FINANCING

In July 1997, the Company issued 3.0 million Depositary Shares, each
representing 1/10 of a Series B Cumulative Step-Up Redeemable Preferred Share,
raising net proceeds of $146.1 million. These securities are not redeemable
prior to September 30, 2007 and offer a cumulative distribution of 7.99% through
September 2012, and 9.99% thereafter. The proceeds of this financing were fully
used to reduce the outstanding balance on the Company's unsecured line of credit
and to fund the development and acquisition of additional rental properties.

In August 1997, the Company issued $100 million of unsecured Pass-through
Asset Trust Securities ("PATS"). The PATS bear interest at a coupon rate of
6.95% and mature on August 15, 2004. The effective rate of the PATS is 7.347%,
which includes the effect of the settlement of a forward Treasury lock agreement
which the Company entered into in April 1997. The Company and an affiliate of
the placement agent for the PATS can effectively agree to reset the interest
rate and remarket the underlying notes with a maturity of August 15, 2011.

The Company reduced the interest rate on its $150.0 million unsecured line
of credit from the 30-day London Interbank Offered Rate ("LIBOR") plus 1.25% to
LIBOR plus 1.00% effective March 27, 1997. Effective August 28, 1997, the
unsecured line of credit was increased to $200.0 million and the interest rate
was reduced to LIBOR plus .80%. This line of credit also includes a "competitive
bid option" and matures in April 2001.

<PAGE>
Concurrently with the Offering, the Company is considering offering
approximately $20 million of Common Stock to an institutional buyer at the
prevailing market price of the stock. There can be no assurance that this
transaction will be consummated.

DEVELOPMENT AND ACQUISITIONS

During the first seven months of 1997, the Company completed development of
and placed in service 10 properties and one property expansion comprising 2.6
million square feet at a total cost of $79.5 million. The Company has 27
properties and one property expansion under development at July 31, 1997
comprising 4.2 million square feet which will have a total cost of $204.1
million upon completion. Also during the first seven months of 1997, the Company
acquired 9 properties with 1.9 million square feet at a total cost of $120.5
million.

These property additions (the "New Properties"), totaling 8.7 million square
feet, consist of 73% industrial, 23% office, and 4% retail projects. The total
cost of the New Properties is expected to be $404.1 million. At July 31, 1997,
the New Properties which have been placed in service are 88% leased, and the New
Properties under construction are 58% pre-leased for a combined total of 73%
leased. The New Properties are expected to provide a weighted average
unleveraged stabilized return on cost (computed as property annual contractual
net operating income ("NOI") divided by total project costs) of 11.3% with
anticipated leasing activity. The annual contractual NOI to be generated from
the New Properties, once placed in service, will be $45.7 million with
anticipated additional leasing. The cost of the New Properties to be placed in
service in the third quarter of 1997 is $47.1 million, in the fourth quarter of
1997 is $78.9 million, and in 1998 is $78.1 million.

The Company's expectations of total cost and weighted average unleveraged
stabilized return on cost constitute forward-looking information that is subject
to risks inherent in the completion of construction of the properties under
development and the leasing of any unleased portion of the properties. Such
risks could cause actual results to differ materially from the Company's
expectations.

CHICAGO, ILLINOIS. In May 1997, the Company entered the Chicago, Illinois
market. Through a joint venture with an institutional investor, the Company
purchased the six-story, 345,200 square foot Central Park of Lisle 96% occupied
office property in Lisle, Illinois, a western suburb of Chicago. The acquisition
also included a 17-acre site, located adjacent to the existing property, for
future office development. The Company is establishing a regional office in
Chicago. The Company believes that the Chicago market will offer additional
profitable development and acquisition opportunities in select sub-markets.
While the Company does not anticipate dominating the Chicago market because of
its magnitude, it believes that entry into the Chicago market is in accordance
with its strategy of entering attractive Midwestern markets.

PENDING ACQUISITIONS

The Company has entered into contracts or letters of intent to purchase
certain properties in St. Louis and in the Chicago suburbs (the "Pending
Acquisitions") for an aggregate purchase price of approximately $247.3 million.
The Company currently expects to complete the Pending Acquisitions by October 1,
1997. However, the purchase of each of the Pending Acquisitions is subject to
various closing conditions. Accordingly, no assurances can be made that the
Company will close any or all of the Pending Acquisitions.

In addition to the Pending Acquisitions, as part of its ongoing business,
the Company continually engages in discussions with other real estate owners
regarding possible portfolio or single asset acquisitions in its current and
other attractive Midwestern markets. No assurances can be made that the Company
will acquire any of the properties or portfolios currently being evaluated.

The following describes each of the Pending Acquisitions.

BAUR PROPERTIES. In August 1997, the Company entered into a letter of
intent to acquire Baur Properties' existing rental properties and operations in
St. Louis, Missouri. Baur Properties has been in operation in St. Louis for over
43 years and is one of the leading suburban office developers and operators in
the Midwest. The Baur rental property portfolio consists of eight suburban
office buildings totaling 904,000 square feet and three industrial buildings
totaling 78,000 square feet. Seven of the suburban office projects are located
in Maryville Centre, one of the premier suburban office parks in St. Louis. The
acquisition will also include undeveloped land to accommodate approximately one
million square feet of additional suburban office development and the property
management and development operations of Baur Properties. Accordingly, Edward T.
Baur, the Chairman of Baur Properties, will become Vice President and General
Manager of the Company's St. Louis operations. The purchase price of this
acquisition is expected to be paid through the assumption of $57.5 million in
existing mortgage debt with a weighted average interest rate of 8.13%, the
payment of approximately $25.0 million in cash and the remainder in Units. Along
with its existing operations in St. Louis, the Company believes this acquisition
will make it the dominant real estate developer in this market. The Company
believes this acquisition is in accordance with its strategy of dominating its
Midwestern markets.

The following table sets forth information regarding the Baur Properties as
of July 31, 1997.

THE COMPANY

The Company is a self-administered and self-managed REIT that began
operations through a related entity in 1972. At June 30, 1997, the Company owned
a diversified portfolio of 262 in-service industrial, office and retail
Properties, encompassing approximately 31.4 million square feet located in seven
states, and 26 buildings and one building expansion encompassing approximately
4.1 million square feet under development. The Company also owned approximately
1,300 acres of unencumbered Land for future development, of which approximately
75% is zoned for industrial use and which is typically located adjacent to the
Properties. The Company provides leasing, management, construction, development
and other tenant-related services for the Properties and certain properties
owned by third parties. The Company has the largest commercial real estate
operations in Indianapolis and Cincinnati and is one of the largest real estate
companies in the Midwest. The Company believes that the Midwest offers a
relatively strong and stable economy compared to other regions of the United
States and provides significant growth potential due to its central location,
established manufacturing base, skilled work force and moderate labor costs.

The Company has developed over 50 million square feet of commercial property
since its founding including an average of approximately 4.1 million square feet
per year during the last five years. In addition, the Company acquired
approximately 8.9 million square feet during the three years ended December 31,
1996. Through the six months ended June 30, 1997, the Company placed in service
2.6 million square feet of new development and acquired 1.8 million square feet
of property.

The Company manages over 43 million square feet of property, including over
8.1 million square feet owned by third parties. The Company manages
approximately 35% and 29% of all competitive suburban office, warehousing and
light manufacturing space in Indianapolis and Cincinnati, respectively. In
addition to providing services to approximately 1,800 tenants in the Properties,
the Company provides such services to over 900 tenants in 92 properties owned by
third parties. Based on market data maintained by the Company, the Company
believes that it was responsible in the first six months of 1997 for
approximately 67% and 34% of the net absorption (gross space leased minus lease
terminations and expirations) of competitive suburban office, warehousing and
light manufacturing space in Indianapolis and Cincinnati, respectively. The
Company believes that its dominant position in its primary markets gives it a
competitive advantage in its real estate activities.

All of the Company's interests in the Properties and Land are held directly
or indirectly by, and substantially all of its operations relating to the
Properties are conducted through, the Operating Partnership. Units in the
Operating Partnership may be exchanged by the holders thereof, other than the
Company, for Common Stock of the Company on a one-for-one basis. Upon an
exchange of Units for Common Stock, the Company's percentage interest in the
Operating Partnership will increase. The Company controls the Operating
Partnership as the sole general partner and owner, as of June 30, 1997, of
approximately 90% of the Units.

BUSINESS STRATEGY

The Company's business objective is to increase its Funds From Operations by
(i) maintaining and increasing property occupancy and rental rates through the
aggressive management of its portfolio of existing properties; (ii) expanding
existing properties; (iii) developing and acquiring new properties; and (iv)
providing a full line of real estate services to the Company's tenants and to
third parties.

The Company believes that the analysis of real estate opportunities and
risks can be done most effectively at regional or local levels. As a result, the
Company intends to continue its emphasis on increasing its market share and
effective rents in its existing markets primarily within the Midwest. The
Company also expects to utilize its approximately 1,300 acres of unencumbered
Land and its many business relationships with more than 2,700 commercial tenants
to expand its build-to-suit business (development projects substantially
pre-leased to a single tenant) and to pursue other development and

S-11
<PAGE>
acquisition opportunities in its existing markets and elsewhere, primarily in
the Midwest. The Company believes that this regional focus will allow it to
assess market supply and demand for real estate more effectively as well as to
capitalize on its strong relationships with its tenant base.

The Company's policy is to seek to develop and acquire substantially
pre-leased Class A commercial properties located in markets with attractive
investment potential for Fortune 500 companies and other quality regional and
local firms. The Company's industrial and suburban office development focuses on
business parks and mixed use developments suitable for development of multiple
projects on a single site and where the Company can create and control the
business environment. These business parks and mixed use developments generally
include restaurants and other amenities which the Company believes create an
atmosphere that is particularly efficient and desirable. The Company's retail
development focuses on community, power and neighborhood centers in its existing
markets. As a fully integrated real estate company, the Company is able to
arrange for or provide to its industrial, office and retail tenants not only
well located and well maintained facilities, but also additional services such
as build-to-suit construction, tenant finish construction, expansion flexibility
and advertising and marketing services.

FINANCING STRATEGY

The Company seeks to maintain a well-balanced, conservative and flexible
capital structure by: (i) currently targeting a ratio of long-term debt to total
market capitalization in the range of 25% to 40%; (ii) extending and sequencing
the maturity dates of its debt; (iii) borrowing primarily at fixed rates; (iv)
generally pursuing current and future long-term debt financings and refinancings
on an unsecured basis; (v) maintaining conservative debt service and fixed
charge coverage ratios; and (vi) maintaining a conservative dividend payout
ratio. Management believes that these strategies have enabled and should
continue to enable the Company to access the debt and equity capital markets for
their long-term requirements such as debt refinancings and financing for
development and acquisitions of additional rental properties. The Company has
demonstrated its ability to access the equity and debt markets to finance the
activities of the Company through recent public offerings of Common Stock,
Preferred Stock and unsecured notes since October 1993 which generated aggregate
net proceeds of $1.24 billion.

MIDWESTERN FOCUS

The Company believes that the Midwest offers a relatively strong and stable
economy compared to other regions of the United States and provides attractive
new opportunities due to its central location, established manufacturing base,
skilled work force and moderate labor costs. In addition, the interstate highway
systems serving Indianapolis, Cincinnati and Columbus, markets in which
approximately 78% and 85% of the Properties, in terms of both dollar value of
Net Effective Rent and square footage, respectively, are located, help make
those cities prime industrial and office property locations.

Employment statistics are generally a useful measure of the viability of a
commercial real estate market because the demand for industrial and office space
in a geographic area is usually linked to the levels of business activity and
disposable income. According to the United States Department of Labor's Bureau
of Labor Statistics, the unemployment rate for June 1997 was 2.6%, 3.6% and 2.8%
in the Indianapolis, Cincinnati and Columbus metropolitan areas, respectively,
compared to 5.0% for the United States. Additionally, total non-farm employment
has increased 15.5%, 11.4% and 16.5% from December 1989 to December 1996 for the
Indianapolis, Cincinnati and Columbus metropolitan areas, respectively, as
compared to 11.0% for the United States.

Management believes that the Company's assets are located in strong real
estate markets with good investment potential. The Spring 1997 issue of
MarketScore, a National Real Estate Index and Ernst & Young Kenneth Leventhal
Real Estate Group publication ("MarketScore"), rated 64 metropolitan areas in
the United States in terms of their real estate investment potential for the
succeeding two years. The study

S-12
<PAGE>
segmented each metropolitan area by property type and considered real estate,
economic and demographic variables such as vacancy rates, construction, rental
trends, job growth, population and household growth, and household income.
Approximately 34.4 million square feet of the Company's in-service and
under-development Properties are in markets considered by MarketScore to have
good or excellent investment potential.

INDIANAPOLIS, INDIANA. With more than 1.5 million residents, Indianapolis
is Indiana's largest metropolitan area. With a central location at the
intersection of four interstate highways, Indianapolis continues to attract new
growth by offering a skilled work force and stable economic base. Indianapolis'
economic base includes distribution, government, manufacturing, retail trade,
service and tourism related industries. According to CB Commercial Real Estate
Group, Inc. ("CB Commercial"), the industrial vacancy rate was 9.5% as of
December 31, 1996. The Indianapolis suburban office market strengthened over the
24-month period ending March 31, 1997. According to CB Commercial, at March 31,
1997, Indianapolis had an 8.5% suburban office vacancy rate compared to a
national average of 10.6%.

CINCINNATI, OHIO. Cincinnati is the second largest metropolitan area in
Ohio with a population of 1.6 million. With an unemployment rate which is below
the national average, Cincinnati's economic base is healthy and diverse.
Balanced between major Fortune 500 employers and entrepreneurial enterprises,
Cincinnati's economic base includes banking, distribution, manufacturing, retail
trade and service related industries. Relatively low taxes, an expanding airport
(a major North American hub for Delta Airlines) and aggressive state and local
incentive packages designed to attract new business have contributed to major
corporate relocations in Cincinnati. Indicative of the economic strength in
Cincinnati, the industrial vacancy rate as reported by CB Commercial declined by
0.7% over the 24 months ended December 31, 1996 to 3.0%, less than half the
national average of 7.3%. As reported by CB Commercial, the Cincinnati suburban
office market vacancy rate declined by 6.1% over the twenty-four month period
ended March 31, 1997 to 8.4%, compared to the national average of 10.6%, and the
Cincinnati downtown office vacancy rate declined 1.2% over the same period to
13.7%.

COLUMBUS, OHIO. The Columbus metropolitan area has a population of
approximately 1.4 million and is the third largest metropolitan area in Ohio.
The city's central location, well-trained work force and high quality of life
have established Columbus as a major transportation and distribution center.
Columbus' economic base includes distribution, government, manufacturing, retail
trade and service-related industries. As reported by CB Commercial, as of
December 31, 1996, the industrial vacancy rate in Columbus was 6.1% compared to
the national average of 7.3%. As of March 31, 1997, the suburban office vacancy
rate in Columbus was 10.6%, equal to the national average.

CLEVELAND, OHIO. Cleveland is the largest metropolitan area in Ohio with a
population of 2.2 million. The city is a major center for industry, technology,
and service industries, including banking, health, research and development and
the legal and accounting professions. Twenty-eight Fortune 500 companies have
located their headquarters in Cleveland. As reported by CB Commercial, as of
December 31, 1996 the industrial vacancy rate in Cleveland was 7.3%, equal to
the national average and, as of March 31, 1997, the suburban office vacancy rate
was 8.4% compared to the national average of 10.6%.

ST. LOUIS, MISSOURI. St. Louis is Missouri's largest metropolitan area with
a population of 2.5 million. With its central location, St. Louis is within 500
miles of one-third of the U.S. population and businesses and it has the lowest
total mileage from the 24 largest metro areas in the mid-U.S. to the same 24
metro areas. Twenty-three Fortune 500 companies have located their headquarters
in St. Louis. As reported by CB Commercial, as of December 31, 1996 the
industrial vacancy rate in St. Louis was 2.5% compared to the national average
of 7.3% and, as of March 31, 1997, the suburban office vacancy rate was 6.2%
compared to the national average of 10.6%.

QUALITY TENANT BASE

The Company's Properties have a diverse and stable base of approximately
1,800 tenants. Many of the tenants are Fortune 500 companies and engage in a
wide variety of businesses, including manufacturing, retailing, wholesale trade,
distribution, and professional services. Approximately 50% of the square footage
of the Properties is occupied by tenants with a net worth based on book value of
$100 million or greater. Approximately 75% of the gross leasable area of the
Properties is occupied by tenants who have been in business for more than 10
years. The Company renewed 84% of the square feet of tenants up for renewal in
the first six months of 1997 on approximately 1.3 million square feet up for
renewal. No single tenant accounts for more than 2.5% of the Company's total
gross effective rent (computed using the average annual rental property revenue
over the terms of the respective leases including landlord operating expense
allowances but excluding additional rent due as operating expense
reimbursements).

The following table sets forth information regarding the 10 largest tenants
of the Properties based upon annualized gross effective rents as of June 30,

USE OF PROCEEDS

The net proceeds to the Company from the sale of the Common Stock offered
hereby are expected to be approximately $192.8 million (approximately $221.8
million if the Underwriters' over-allotment options are exercised in full). The
Company presently intends to use the net proceeds as well as the net proceeds of
its PATS offering of approximately $100.0 million to retire the outstanding
balance on its lines of credit (the "Lines of Credit") and to fund development
and acquisition of additional rental properties, including the cash portion of
the Pending Acquisitions, expected to total in excess of $120 million. The
remaining costs to be funded on the 4.2 million square feet of property under
development at July 31, 1997 total $108.8 million with $73.7 million expected to
be spent by December 31, 1997. See "Prospectus Supplement Summary--Recent
Developments." The Lines of Credit are expected to have an outstanding balance
of approximately $65.0 million on September 15, 1997, bearing interest at LIBOR
plus .75% to .80%.

On July 24, 1997, the Company's Board of Directors raised its regular
quarterly common dividend from $.255 per share to $.295 per share, payable on
August 29, 1997 to common shareholders of record on August 15, 1997. The new
dividend is an increase of $.16 per year which is a 15.7% increase over the
previous amount. This dividend equals $1.18 on an annualized basis.

The Company has announced that its Board of Directors anticipates the
Company's regular quarterly dividend amount to be $.30 per common share on a
post Stock-Split basis. This would equate to a dividend increase of 1.7% and
follows the Company's 15.7% dividend increase announced July 24, 1997. The
official declaration for this new dividend is expected to be on October 23,
1997, the date of the Company's next regularly scheduled Board of Directors'
meeting.

<PAGE>
Since its organization in 1986, the Company has paid regular and
uninterrupted dividends. The Company intends to continue to declare quarterly
dividends on its Common Stock. However, no assurances can be given as to the
amounts of future dividends as such dividends are subject to the Company's cash
flow from operations, earnings, financial condition, capital requirements and
such other factors as the Board of Directors deems relevant. The Company has
determined that approximately 1% of the per share distribution for 1996
represented return of capital to the shareholders for income tax purposes. No
assurance can be given that such percentage will not change in future years.

DIVIDEND REINVESTMENT PLAN

The Company has an Automatic Dividend Reinvestment Plan (the "Plan") which
allows shareholders to acquire additional shares of Common Stock by
automatically reinvesting cash dividends. Common Stock is acquired pursuant to
the Plan at a price equal to the prevailing market price of such Common Stock
less a 4% discount, without payment of any brokerage commission or service
charge. The Plan also allows persons to purchase Common Stock at a price equal
to the prevailing market price of such Common Stock (without any discount but
without payment of any brokerage commission or service charge) in the same
manner as cash dividends are invested in amounts of not less than $100 ($25 for
automated funds transfers) and not more than $5,000 per month for participating
shareholders and in amounts of not less than $250 and more than $5,000 per month
for initial investments by persons who are not shareholders. Shareholders who do
not participate in the Plan continue to receive cash dividends, as declared.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF
FINANCIAL CONDITION AND RESULTS OF OPERATIONS

OVERVIEW

The Company's operating results depend primarily upon income from the rental
operations of its industrial, office and retail properties located in its
primary markets. This income from rental operations is substantially influenced
by the supply and demand for the Company's rental space in its primary markets.
In addition, the Company's continued growth is dependent upon its ability to
maintain occupancy rates and increase rental rates of its in-service portfolio
and to continue development and acquisition of additional rental properties.

The Company's primary markets in the Midwest have continued to offer strong
and stable local economies and have provided attractive new development
opportunities because of their central location, established manufacturing base,
skilled work force and moderate labor costs. Consequently, the Company's
occupancy rate of its in-service portfolio has exceeded 92% the last two years
and was at 95.7% at June 30, 1997. The Company expects to continue to maintain
its overall occupancy levels at comparable levels and also expects to be able to
increase rental rates as leases are renewed or new leases are executed. This
stable occupancy as well as increasing rental rates should improve the Company's
results of operations from its in-service properties. The Company's strategy for
continued growth also includes developing and acquiring additional rental
properties in its primary markets and expanding into other attractive Midwestern
markets.

The following table sets forth information regarding the Company's
in-service portfolio of rental properties as of June 30, 1997 and 1996 (in
thousands, except percentages):

</TABLE>

Management expects occupancy of the in-service property portfolio to remain
stable because (i) only 5.5% and 10.8% of the Company's occupied square footage
is subject to leases expiring in the remainder of 1997 and in 1998,
respectively, and (ii) the Company's renewal percentage averaged 80%, 65% and
73% in 1996, 1995 and 1994, respectively. For the first six months of 1997, the
renewal percentage was 84%.

This stable occupancy, along with stable rental rates in each of the
Company's markets, will allow the in-service portfolio to continue to provide a
comparable or increasing level of earnings from rental operations. The Company
also expects to realize growth in earnings from rental operations through (i)
the development and acquisition of additional rental properties in its primary
markets; (ii) the expansion into other attractive Midwestern markets; and (iii)
the completion of the 4.1 million square feet of properties under development at
June 30, 1997 over the next five quarters. The 4.1 million square feet of
properties under development should provide future earnings from rental
operations growth for the Company as they are placed in service as follows (in

COMPARISON OF SIX MONTHS ENDED JUNE 30, 1997 TO SIX MONTHS ENDED JUNE 30, 1996

RENTAL OPERATIONS. The Company increased its in-service portfolio of rental
properties from 219 properties comprising 23.2 million square feet at June 30,
1996 to 262 properties comprising 31.4 million square feet at June 30, 1997
through the acquisition of 28 properties totaling 3.6 million square feet and
the completion of 19 properties and four building expansions totaling 5.1
million square feet developed by the Company. The Company also disposed of four
properties totaling 495,000 square feet. These 43 net additional rental
properties primarily account for the $28.2 million increase in revenues from
Rental Operations from 1996 to 1997. The Company also received a $1.2 million
net lease termination payment made by a tenant in one of the Company's office
properties which is included in rental income for the six months ended June 30,
1997. The increase from 1996 to 1997 in rental expenses, real estate taxes and
depreciation and amortization expense is also a result of the additional 43
in-service rental properties.

Interest expense increased by approximately $3.3 million from $14.6 million
for the six months ended June 30, 1996 to $17.9 million for the six months ended
June 30, 1997 due to additional unsecured debt issued in its medium-term note
program in the last two quarters of 1996 to fund the development and acquisition
of additional rental properties.

As a result of the above-mentioned items, earnings from rental operations
increased $14.0 million from $23.2 million for the six months ended June 30,
1996 to $37.2 million for the six months ended June 30, 1997.

SERVICE OPERATIONS. Service Operation revenues decreased to $9.1 million
for the six months ended June 30, 1997 as compared to $9.5 million for the six
months ended June 30, 1996. This decrease was primarily the result of a decrease
in construction management fees caused by certain higher profit third-party
construction projects that were in process during the six months ended June 30,
1996 which resulted in higher revenue margins. Service Operation operating
expenses increased from $6.7 million to $6.9 million for the six months ended
June 30, 1997 as compared to the six months ended June 30, 1996 primarily as a
result of an increase in operating expenses resulting from the overall growth of
the Company.

S-22
<PAGE>
As a result of the above-mentioned items, earnings from Service Operations
decreased from $2.8 million for the six months ended June 30, 1996 to $2.2
million for the six months ended June 30, 1997.

GENERAL AND ADMINISTRATIVE EXPENSE. General and administrative expense
increased from $2.3 million for the six months ended June 30, 1996 to $2.9
million for the six months ended June 30, 1997 primarily as a result of
increased state and local taxes due to the growth in revenues and net income of
the Company.

OTHER INCOME (EXPENSE). Interest income decreased from $613,000 for the six
months ended June 30, 1996 to $427,000 for the six months ended June 30, 1997
primarily as a result of interest income which was earned on certain escrows
during the six months ended June 30, 1996 which were refunded later in 1996.
Other expense consists of the write-off of costs incurred during the pursuit of
various build-to-suit development projects or the acquisition of real estate
assets. During the six months ended June 30, 1997, approximately $312,000 of
costs were written-off in connection with the decision to terminate the pursuit
of the acquisition of a large real estate portfolio.

NET INCOME AVAILABLE FOR COMMON SHARES. Net income available for common
shares for the six months ended June 30, 1997 was $29.7 million compared to net
income available for common shares of $21.9 million for the six months ended
June 30, 1996. This increase results primarily from the operating result
fluctuations in rental and service operations explained above.

LIQUIDITY AND CAPITAL RESOURCES

Net cash provided by operating activities totaling $71.5 million and $39.1
million for the six months ended June 30, 1997 and 1996, respectively,
represents the primary source of liquidity to fund distributions to
shareholders, unitholders and the other minority interests and to fund recurring
costs associated with the renovation and re-letting of the Company's properties.
This increase is primarily a result of, as discussed above under "Results of
Operations," the increase in net income resulting from the expansion of the
in-service portfolio through development and acquisitions of additional rental
properties.

Net cash used by investing activities totaling $175.4 million and $93.6
million for the six months ended June 30, 1997 and 1996, respectively,
represents the investment of funds by the Company to expand its portfolio of
rental properties through the development and acquisition of additional rental
properties net of proceeds received from property sales. In 1997, $153.3 million
was invested in the development and acquisition of additional rental properties
and the acquisition of land held for development. In 1996, the investment in the
development and acquisition of additional rental properties and land held for
development was $132.7 million. During the six months ended June 30, 1997, the
Company invested over $30 million in a newly formed joint venture with an
institutional investor which allowed the joint venture to purchase a 345,000
square foot office property in Chicago, Illinois which was over 95% occupied.

Net cash provided by financing activities totaling $101.2 million and $49.0
million for the six months ended June 30, 1997 and 1996, respectively,
represents the source of funds from equity and debt offerings and borrowings on
the lines of credit to fund the Company's investing activities. Also included in
financing activities are the distribution of funds to shareholders and minority
interests. In 1996, the Company received $126.1 million of net proceeds from a
common equity offering which was used to pay down amounts outstanding on the
unsecured line of credit and to fund current development and acquisition
activity. In January 1997, the Company received $56.7 million of net proceeds
from a common equity offering which was used to pay down amounts outstanding on
the unsecured line of credit and to fund current development activity. During
the six months ended June 30, 1997, the Company also received $7.0 million of
net proceeds from the issuance of common stock under its Direct Stock Purchase
and Dividend Reinvestment Plan and the exercise of employee stock options.

The Company has a $200 million unsecured line of credit which matures in
April 2001. In January 1996, the borrowing rate was LIBOR plus 1.625%. In
September 1996, the borrowing rate was reduced to LIBOR plus 1.25%. On March 27,
1997, the borrowing rate was further reduced to LIBOR plus 1.00%.

S-23
<PAGE>
On August 28, 1997, the borrowing rate was reduced to LIBOR plus .80%. The line
of credit also includes a "competitive bid option" and matures in April 2001.
The Company also has a demand $10 million secured revolving credit facility
which is available to provide working capital. This facility bears interest
payable at the 30-day LIBOR rate plus .75%.

The Company currently has on file Form S-3 Registration Statements with the
Securities and Exchange Commission ("Shelf Registrations") which, after
completion of the Offerings, will have remaining availability of approximately
$556 million to issue common stock, preferred stock or unsecured debt
securities. The Company intends to issue additional equity or debt under these
Shelf Registrations as capital needs arise to fund the development and
acquisition of additional rental properties.

The Company intends to maintain a conservative capital structure. The
Company's debt to total market capitalization ratio at June 30, 1997 was 29.1%.
Following the Offerings, the Company's debt to total market capitalization ratio
will be 23.7% based on a market price of the Company's Common Stock of $21 7/16
per share.

The total debt outstanding at June 30, 1997 consists of notes totaling
$614.9 million with a weighted average interest rate of 7.44% maturing at
various dates through 2017. The Company has $343.0 million of unsecured debt and
$271.9 million of secured debt outstanding at June 30, 1997. Scheduled principal
amortization of such debt totaled $1.5 million for the six months ended June 30,
1997.

Following is a summary of the scheduled future amortization and maturities
of the Company's indebtedness at June 30, 1997 (in thousands):

The 1997 maturities consist of the outstanding balance on the Company's $10
million demand secured line of credit. The 1998 maturities consist mainly of the
outstanding balance on the Company's $150 million unsecured line of credit. This
outstanding balance was repaid with a portion of the proceeds of the $146.1
million Series B Cumulative Step-Up Premium Rate Preferred Shares which were
issued in July 1997.

The Company intends to pay regular quarterly dividends from net cash
provided by operating activities. A quarterly dividend of $.59 per Common Share
was declared on July 24, 1997 payable on August 29, 1997 to shareholders of
record on August 15, 1997, which represents an annualized dividend of $2.36 per
share. A quarterly dividend of $.56875 per depositary share of Series A
Preferred Shares was declared on July 24, 1997 which is payable on August 29,
1997 to preferred shareholders of record on July 24, 1997. On July 24, 1997, the
Board of Directors declared a dividend of $.88778 per depositary share

S-24
<PAGE>
on the Series B Cumulative Step-up Redeemable Preferred Shares. The dividend is
payable on September 30, 1997 to preferred shareholders of record on September
16, 1997 and is applicable to the period beginning July 11, 1997 and ending
September 30, 1997.

FUNDS FROM OPERATIONS

Management believes that FFO, which is defined by NAREIT as net income or
loss excluding gains or losses from debt restructuring and sales of property
plus depreciation and amortization, and after adjustments for minority interest,
unconsolidated partnerships and joint ventures (adjustments for minority
interest, unconsolidated partnerships and joint ventures are calculated to
reflect FFO on the same basis), is the industry standard for reporting the
operations of real estate investment trusts.

The following table reflects the calculation of the Company's FFO for the
six months ended June 30 as follows (in thousands):

</TABLE>

The increase in FFO for the six months ended June 30, 1997 compared to the
six months ended June 30, 1996 results primarily from the increased in-service
rental property portfolio as discussed above under "Results of Operations."

While management believes that FFO is the most relevant and widely used
measure of the Company's operating performance, such amount does not represent
cash flow from operations as defined by generally accepted accounting
principles, should not be considered as an alternative to net income as an
indicator of the Company's operating performance, and is not indicative of cash
available to fund all cash flow needs.

PROPERTIES

GENERAL

The Company owns a diversified portfolio of properties which includes (i)
the in-service Properties, consisting of 262 industrial, office and retail
properties located in Indiana, Ohio, Illinois, Tennessee, Kentucky, Wisconsin

INDUSTRIAL PROPERTIES

The 157 industrial Properties are primarily located in industrial or
business parks that have been developed by the Company and consist of 109 bulk
distribution facilities and 48 service center facilities. Approximately 86% of
the square footage of the industrial Properties is contained in bulk
distribution facilities. The bulk distribution facilities accommodate the needs
of large warehouse and distribution users with ceiling clear heights of 20 feet
or more while providing leased space to many large tenants including users of
more than 500,000 square feet. The service center facilities are also known as
flex buildings or light industrial properties which generally have 12 to 18 foot
ceiling heights and a combination of drive-up and dock loading access. These
service center facilities accommodate users of 1,200 square feet and up. The

S-27
<PAGE>
diversity of the industrial buildings allows the Company to cater to many
segments of the industrial market and renders the Company less dependent upon
any specific market segment. Over 89% of the industrial Properties are in the
Company's markets of Indianapolis, Cincinnati and Columbus.

OFFICE PROPERTIES

The Company owns a portfolio of 81 office Properties, including 72 suburban
office buildings which range from single-story to mid-rise and are located in
developed business parks and mixed use developments with excellent interstate
access and visibility. Six of the suburban office buildings are medical
buildings, including a single tenant facility with a 20 year lease and two
multi-tenant properties attached to a hospital. In addition, the Company owns
three downtown office buildings consisting of two new high-rise buildings and
one rehabilitated building. The Company believes that these primarily Class A
office Properties are among the highest quality available to tenants in its
markets. This diverse mix of office buildings is occupied by tenants spanning
all segments of the office market.

RETAIL PROPERTIES

The retail Properties, which cater to a variety of retail markets, include
one regional shopping center, 12 neighborhood shopping centers, three shopping
centers designed primarily to serve the business parks in which they are located
and eight free-standing single-tenant buildings. The regional and neighborhood
shopping centers either have well known anchor tenants such as Wal-Mart and Pet
Food Supermarket, or are located adjacent to major retailers such as Kroger or
in areas where other large commercial facilities draw consumers. The retail
Properties are generally located in upscale suburban and high growth areas.

LAND

Substantially all of the approximately 1,300 acres of unencumbered Land is
located adjacent to the Properties in industrial or business parks that have
been developed by the Company. Approximately 75% of the Land is zoned for
industrial use, with the remainder zoned for either office or retail use. All of
the Land is unencumbered, has available to it appropriate utilities and is ready
for immediate development. The Company believes that approximately 17 million
square feet of commercial development can be constructed on the Land. The
Company believes that the Land gives it a competitive advantage over other real
estate companies operating in its markets.

CERTAIN FEDERAL INCOME TAX CONSIDERATIONS

For a discussion of material federal income tax consequences applicable to
distributions to shareholders and the Company's election to be taxed as a REIT,
see "Federal Income Tax Considerations" in the accompanying Prospectus.

Prospective purchasers should be aware that the recently enacted Taxpayer
Relief Act of 1997 (the "1997 Act") made numerous changes to the Code, including
reducing the maximum tax imposed on net capital gains from the sale of assets
held for more than 18 months by individuals, trusts and estates. The 1997 Act
also makes certain changes to the requirements to qualify as a REIT and to the
taxation of REITs and their shareholders.

The 1997 Act contains significant changes to the taxation of capital gains
of individuals, trusts and estates and certain changes to the REIT Requirements
and the taxation of REITs. For gains realized after July 28, 1997, and subject
to certain exceptions, the maximum rate of tax on net capital gains of
individuals, trusts and estates from the sale or exchange of assets held for
more than 18 months has been reduced to 20%, and the maximum rate is reduced to
18% for assets acquired after December 31, 2000 and held for more than five
years. For taxpayers who would be subject to a maximum tax rate of 15%, the rate
on net capital gains is reduced to 10%, and effective for taxable years
commencing after December 31, 2000, the rate is reduced to 8% for assets held
for more than five years. The maximum rate for net capital gains attributable to
the sale of depreciable real property held for more than 18 months is 25% to the
extent of the deductions for depreciation with respect to such property.
Long-term capital gain allocated to a shareholder by the Company will be subject
to the 25% rate to the extent that the gain does not exceed depreciation on real
property sold by the Company. The maximum rate of capital gains tax for capital
assets held more than one year but not more than 18 months remains at 28%. The
taxation of capital gains of corporations was not changed by the 1997 Act.

The 1997 Act also includes several provisions that are intended to simplify
the taxation of REITs. These provisions are effective for taxable years
beginning after the date of enactment of the 1997 Act which, as to the Company,
is its taxable year commencing January 1, 1998. First, in determining whether a
REIT satisfies the income tests, a REIT's rental income from a property will not
cease to qualify as "rents from real property" merely because the REIT performs
services for a tenant other than permitted customary services if the amount that
the REIT is deemed to have received as a result of performing impermissible
services does not exceed one percent of all amounts received directly or
indirectly by the REIT with respect to such property. The amount that a REIT
will be deemed to have received for performing impermissible services is at
least 150% of the direct cost to the REIT of providing those services. Second,
certain non-cash income, including income from cancellation of indebtedness and
original issue discount will be excluded from income in determining the amount
of dividends that a REIT is required to distribute. Third, a REIT may elect to
retain and pay income tax on any net long-term capital gains and require its
shareholders to include such undistributed net capital gains in their income. If
a REIT makes such an election, the REIT's shareholders would receive a tax
credit attributable to their share of capital gains tax paid by a REIT on the
undistributed net capital gains that was included in the shareholders' income,
and such shareholders will receive an increase in the basis of their shares in
the amount of undistributed net capital gain included in their income reduced by
the amount of the credit. Fourth, the 1997 Act repeals the requirement that a
REIT receive less than 30% of its gross income from the sale or disposition of
stock or securities held for less than one year, gain from prohibited
transactions, and gain from certain sales of real property held less than four
years. Finally, the 1997 Act contains a number of technical provisions that
reduce the risk that a REIT will inadvertently cease to qualify as a REIT.

discount per share are identical under the U.S. Underwriting Agreement and the
International Underwriting Agreement.

In each Underwriting Agreement, the U.S. Underwriters and the International
Managers have agreed, subject to the terms and conditions set forth therein, to
purchase all of the shares being sold pursuant to each such Underwriting
Agreement if any of such shares of Common Stock are purchased. Under certain
circumstances, the commitments of nondefaulting U.S. Underwriters or
International Managers may be increased. The closings with respect to the sale
of the shares to be purchased by the International Managers and the U.S.
Underwriters are conditioned one upon the other.

The International Managers have advised the Company that they propose
initially to offer the Common Stock to the public at the public offering price
set forth on the cover page of this Prospectus Supplement, and to certain
dealers at such price less a concession not in excess of $.63 per share. The
International Managers may allow, and such dealers may reallow, a discount not
in excess of $.10 to certain other dealers. After the Offerings, the public
offering price, concession and discounts may be changed.

The Company has been informed that the U.S. Underwriters and the
International Managers have entered into an intersyndicate agreement (the
"Intersyndicate Agreement") that provides for the coordination of their
activities. Under the terms of the Intersyndicate Agreement, the U.S.
Underwriters and the International Managers are permitted to sell shares of
Common Stock to each other for purposes of resale

<PAGE>
at the price per share to the public on the cover page of this Prospectus
Supplement, less an amount not greater than the selling concession. Under the
terms of the Intersyndicate Agreement, the International Managers and any dealer
to whom they sell shares of Common Stock will not offer to sell or sell shares
of Common Stock to persons who are United States persons or Canadian persons or
to persons they believe intend to resell to persons who are United States
persons or Canadian persons, and the U.S. Underwriters and any dealer to whom
they sell shares of Common Stock will not offer to sell or sell shares of Common
Stock to persons who are non-United States and non-Canadian persons or to
persons they believe intend to resell to persons who are non-United States and
non-Canadian persons, except in each case for transactions pursuant to the
Intersyndicate Agreement.

Each International Manager has agreed that (i) it has not offered or sold,
and it will not offer or sell, directly or indirectly, any shares of Common
Stock offered hereby in the United Kingdom by means of any document except in
circumstances which do not constitute an offer to the public within the meaning
of the Companies Act 1985, (ii) it has complied and will comply with all
applicable provisions of the Financial Services Act 1986 with respect to
anything done by it in relation to the shares of Common Stock in, from or
otherwise involving the United Kingdom, and (iii) it has only issued or passed
on and will only issue or pass on in the United Kingdom any document received by
it in connection with the issuance of shares of Common Stock to a person who is
of a kind described in Article 11(3) of the Financial Services Act 1986
(Investment Advertisements) (Exemptions) Order 1996 or is a person to whom the
document may otherwise lawfully be issued or passed on.

Purchasers of shares of Common Stock offered hereby may be required to pay
stamp taxes and other charges in accordance with the laws and practices of the
country of purchase, in addition to the price per share to the public set forth
on the cover page of this Prospectus Supplement.

The Company has granted an option to the International Managers, exercisable
during the 30-day period after the date of this Prospectus Supplement, to
purchase up to 285,000 additional shares of Common Stock at the price to the
public set forth on the cover page of this Prospectus Supplement, less the
underwriting discount. The International Managers may exercise this option only
to cover over-allotments, if any. If the International Managers exercise this
option, each of the International Managers will have a firm commitment, subject
to certain conditions, to purchase approximately the same percentage thereof
which the number of shares of Common Stock to be purchased by it shown in the
foregoing table bears to the 1,900,000 shares of Common Stock offered hereby.
The Company has granted an option to the U.S. Underwriters, exercisable during
the 30-day period after the date of this Prospectus Supplement, to purchase up
to 1,140,000 additional shares of Common Stock solely to cover over-allotments,
if any, on terms similar to those granted to the International Managers.

The Company has agreed to indemnify the several Underwriters against certain
liabilities, including liabilities under the Securities Act of 1933, as amended,
or to contribute to payments the Underwriters may be required to make in respect
thereof.

The Company and the executive officers of the Company and the Directors have
agreed that for a period of 90 days from the date of this Prospectus Supplement
they will not, without prior and written consent of the International Managers,
offer, sell or otherwise dispose of any shares of Common Stock or any other
security convertible into or exercisable for shares of Common Stock (except
pursuant to the Company's stock option or dividend reinvestment plans and
certain other agreements).

In connection with the Offerings, the rules of the Securities and Exchange
Commission permit the U.S. Representatives and the International Managers to
engage in certain transactions that stabilize the price of the Common Stock.
Such transactions may consist of bids or purchases for the purpose of pegging,
fixing or maintaining the price of the Common Stock.

If the U.S. Underwriters or International Managers create a short position
in the Common Stock in connection with the Offerings (I.E., if they sell more
shares of Common Stock than are set forth on the

S-32
<PAGE>
cover page of this Prospectus Supplement), the U.S. Representatives and the
International Managers, respectively, may reduce that short position by
purchasing Common Stock in the open market. The U.S. Representatives and the
International Managers, respectively, also may elect to reduce any short
position by exercising all or part of the over-allotment options described
herein.

The U.S. Representatives and the International Managers also may impose a
penalty bid on certain Underwriters and selling group members. This means that
if the U.S. Representatives and the International Managers purchase shares of
Common Stock in the open market to reduce the U.S. Underwriters' or
International Managers' short position or to stabilize the price of the Common
Stock, they may reclaim the amount of the selling concession from the
Underwriters and selling group members who sold those shares as part of the
Offerings.

In general, purchases of a security for the purpose of stabilization or to
reduce a syndicate short position could cause the price of the security to be
higher than it might otherwise be in the absence of such purchases. The
imposition of a penalty bid might have an effect on the price of a security to
the extent that it were to discourage resales of the security by purchasers in
the Offerings.

Neither the Company nor any of the Underwriters makes any representation or
prediction as to the direction or magnitude of any effect that the transactions
described above may have on the price of the Common Stock. In addition, neither
the Company nor any of the Underwriters makes any representation that the U.S.
Representatives or the International Managers will engage in such transactions
or that such transactions, once commenced, will not be discontinued without
notice.

Merrill Lynch from time to time provides investment banking and financial
advisory services to the Company. Merrill Lynch also acted as representative of
various underwriters in connection with public offerings of the Company's Common
Stock, Depositary Shares and debt securities in 1993 through 1997.
