                   THE COMPANY AND THE OPERATING PARTNERSHIP
 
    The  Company is a self-administered  and self-managed real estate investment
trust that began operations through a related entity in 1972. At March 31, 1997,
the Company owned direct or indirect interests in a portfolio of 250  in-service
industrial,  office and retail properties (the "Properties"), together with over
1,100 acres of  land (the  "Land") for  future development.  The Properties  are
located  in Indiana, Ohio, Illinois, Kentucky, Michigan, Missouri, Tennessee and
Wisconsin. As of  March 31,  1997, the Properties  contained approximately  27.7
million  square  feet, which  were approximately  95.5% leased  to approximately
1,800 tenants.
 
    All of the Company's interests in the  Properties and Land are held by,  and
substantially  all of  its operations  relating to  the Properties  and Land are
conducted through, the Operating Partnership. The Operating Partnership holds  a
100% interest in all but 65 of the Properties and substantially all of the Land.
The  Company controls the Operating Partnership  as the sole general partner and
owner, as of March 31, 1997, of approximately 90.3% of the outstanding units  of
voting  partnership interest of the  Operating Partnership ("Units"). Each Unit,
other than those held by  the Company, may be  exchanged by the holder  thereof,
subject   to  certain  holding  periods,  for  one  share  (subject  to  certain
adjustments) of the Common Stock. With  each such exchange, the number of  Units
owned  by the Company  and, therefore, the Company's  percentage interest in the
Operating Partnership, will increase.
 
    In addition to owning the Properties and the Land, the Operating Partnership
also provides services associated with leasing, property management, real estate
development,  construction  and  miscellaneous  tenant  services  (the  "Related
Businesses")  for the Properties. The  Company also provides services associated
with the  Related  Businesses to  third  parties through  Duke  Realty  Services
Limited Partnership on a fee basis.
 
    The  Company's  experienced  staff  provides a  full  range  of  real estate
services from executive  offices headquartered in  Indianapolis, and from  seven
regional  offices  located  in  the  Cincinnati,  Cleveland,  Columbus, Decatur,
Detroit, Nashville and St. Louis metropolitan areas.
 
    The Company is an  Indiana corporation that  was originally incorporated  in
the  State of Delaware  in 1985, and  reincorporated in the  State of Indiana in
1992. The  Operating Partnership  is  an Indiana  limited partnership  that  was
formed  in 1993. The Company's and the Operating Partnership's executive offices
are located at 8888 Keystone Crossing, Suite 1200, Indianapolis, Indiana  46240,
and their telephone number is (317) 574-3531.
 
                                USE OF PROCEEDS
 
    The  Company is required, by  the terms of the  partnership agreement of the
Operating Partnership, to invest the net  proceeds of any sale of Common  Stock,
Preferred  Stock or Depositary  Shares in the  Operating Partnership in exchange
for additional Units or  preferred Units, as the  case may be. Unless  otherwise
specified in the applicable Prospectus Supplement, the Company and the Operating
Partnership  intend to  use the  net proceeds  from the  sale of  Securities for
general  corporate  purposes,  including  the  development  and  acquisition  of
additional  rental properties and other acquisition transactions, the payment of
certain  outstanding  debt,  and  improvements  to  certain  properties  in  the
Company's portfolio.

    Company maintained a different capital structure. As a result, although  the
    original  properties have historically generated positive net cash flow, the
    financial statements of  the Company  show net  losses for  the fiscal  year
    ended  December  31, 1992.  Consequently, the  computation  of the  ratio of
    earnings to  fixed charges  for  such period  indicates that  earnings  were
    inadequate  to cover  fixed charges  by approximately  $0.7 million  for the
    fiscal year ended December 31, 1992.
 
   
    The Company's and the  Operating Partnership's ratios  of earnings to  fixed
charges  for  the  three  months  ended  March  31,  1997  were  2.30  and 2.32,
respectively.
    
 
    For purposes of  computing these  ratios, earnings have  been calculated  by
adding  fixed charges, excluding  capitalized interest, to  income (loss) before
gains or losses on property sales  and (if applicable) minority interest in  the
Operating  Partnership. Fixed charges consist (if applicable) of interest costs,
whether expensed or capitalized,  the interest component  of rental expense  and
amortization of debt issuance costs.
 
    The  recapitalization  of  the  Company  effected  in  connection  with  the
reorganization permitted the Company  to significantly deleverage, resulting  in
an  improved ratio of  earnings to fixed  charges for periods  subsequent to the
reorganization.
 
                         DESCRIPTION OF DEBT SECURITIES
 
    The Debt Securities  will be  issued under an  Indenture (the  "Indenture"),
between  the Operating  Partnership and The  First National Bank  of Chicago, as
trustee. The  Indenture  is incorporated  by  reference  as an  exhibit  to  the
Registration  Statement of which this Prospectus is  a part and is available for
inspection at  the corporate  trust office  of the  trustee at  14 Wall  Street,
Eighth  Floor, New York, New  York 10005 or as  described above under "Available
Information." The Indenture is subject to, and governed by, the Trust  Indenture
Act  of 1939, as amended (the "TIA"). The statements made herein relating to the
Indenture and  the Debt  Securities to  be issued  thereunder are  summaries  of
certain provisions thereof and do not purport to be complete and are subject to,
and  are qualified  in their  entirety by  reference to,  all provisions  of the
Indenture and such Debt Securities. All section references appearing herein  are
to  sections of the Indenture, and capitalized terms used but not defined herein
shall have the respective meanings set forth in the Indenture.
 
GENERAL
 
    The Debt Securities will be  direct, unsecured obligations of the  Operating
Partnership  and will rank  equally with all  other unsecured and unsubordinated
indebtedness of  the  Operating  Partnership.  At  March  31,  1997,  the  total
outstanding  debt  of the  Operating Partnership  was  $506.1 million,  of which
$261.1 million was secured debt and $245.0 million was unsecured debt. The  Debt
Securities  may be issued without limit as to aggregate principal amount, in one
or   more   series,    in   each    case   as   established    from   time    to
 
                                       4

time  in  or pursuant  to  authority granted  by a  resolution  of the  Board of
Directors of the Company as sole general partner of the Operating Partnership or
as established in one or more indentures supplemental to the Indenture. All Debt
Securities of  one series  need  not be  issued at  the  same time  and,  unless
otherwise provided, a series may be reopened, without the consent of the holders
of  the  Debt  Securities  of  such series,  for  issuances  of  additional Debt
Securities of such series (Section 301).
 
    The Indenture  provides  that  there  may be  more  than  one  trustee  (the
"Trustee")  thereunder,  each  with  respect  to  one  or  more  series  of Debt
Securities. Any  Trustee under  the  Indenture may  resign  or be  removed  with
respect to one or more series of Debt Securities, and a successor Trustee may be
appointed  to act with respect  to such series (Section  608). In the event that
two or more persons are  acting as Trustee with  respect to different series  of
Debt  Securities, each  such Trustee  shall be  a trustee  of a  trust under the
Indenture separate and apart  from the trust administered  by any other  Trustee
(Section  609), and, except as otherwise  indicated herein, any action described
herein to be taken by a Trustee may  be taken by each such Trustee with  respect
to,  and only  with respect to,  the one or  more series of  Debt Securities for
which it is Trustee under the Indenture.
 
    Reference is made  to the Prospectus  Supplement relating to  the series  of
Debt Securities being offered for the specific terms thereof, including:
 
    (1) the title of such Debt Securities;
 
    (2) the  aggregate principal amount of such Debt Securities and any limit on
        such aggregate principal amount;
 
    (3) the percentage of  the principal  amount at which  such Debt  Securities
        will  be issued  and, if  other than  the principal  amount thereof, the
        portion of  the principal  amount thereof  payable upon  declaration  of
        acceleration of the maturity thereof;
 
    (4) the  date or dates, or the method for determining such date or dates, on
        which the principal of such Debt Securities will be payable;
 
    (5) the rate or rates  (which may be  fixed or variable),  or the method  by
        which  such  rate  or rates  shall  be  determined, at  which  such Debt
        Securities will bear interest, if any;
 
    (6) the date or  dates, or the  method for determining  such date or  dates,
        from  which  any  interest will  accrue,  the  dates on  which  any such
        interest will be  payable, the  record dates for  such interest  payment
        dates,  or the method  by which any  such date shall  be determined, the
        person to whom such interest shall be payable, and the basis upon  which
        interest  shall be calculated  if other than  that of a  360-day year of
        twelve 30-day months;
 
    (7) the place or  places where the  principal of (and  premium, if any)  and
        interest,  if any,  on such Debt  Securities will be  payable, such Debt
        Securities may be surrendered for  registration of transfer or  exchange
        and  notices or demands to or  upon the Operating Partnership in respect
        of such Debt Securities and the Indenture may be served;
 
    (8) the period or periods within which, the price or prices at which and the
        terms and conditions upon which such Debt Securities may be redeemed, as
        a whole or in part, at the  option of the Operating Partnership, if  the
        Operating Partnership is to have such an option;
 
    (9) the obligation, if any, of the Operating Partnership to redeem, repay or
        purchase  such Debt Securities pursuant to any sinking fund or analogous
        provision or  at the  option of  a  holder thereof,  and the  period  or
        periods  within which, the  price or prices  at which and  the terms and
        conditions upon which such Debt  Securities will be redeemed, repaid  or
        purchased, as a whole or in part, pursuant to such obligation;
 
                                       5

   (10) if  other than  U.S. dollars, the  currency or currencies  in which such
        Debt Securities  are denominated  and payable,  which may  be a  foreign
        currency  or  units of  two or  more foreign  currencies or  a composite
        currency or currencies, and the terms and conditions relating thereto;
 
   (11) whether the amount of payments of principal of (and premium, if any)  or
        interest,  if  any,  on  such Debt  Securities  may  be  determined with
        reference to an index, formula or other method (which index, formula  or
        method  may, but need not be,  based on a currency, currencies, currency
        unit or units  or composite currency  or currencies) and  the manner  in
        which such amounts shall be determined;
 
   (12) the  events  of default  or covenants  of such  Debt Securities,  to the
        extent different from or in addition to those described herein;
 
   (13) whether such  Debt  Securities will  be  issued in  certificated  and/or
        book-entry form;
 
   (14) whether  such Debt Securities will be  in registered or bearer form and,
        if in registered form,  the denominations thereof  if other than  $1,000
        and   any  integral  multiple  thereof  and,  if  in  bearer  form,  the
        denominations thereof  if other  than $5,000  and terms  and  conditions
        relating thereto;
 
   (15) the  applicability, if  any, of  the defeasance  and covenant defeasance
        provisions described herein, or any modification thereof;
 
   (16) if such  Debt Securities  are to  be issued  upon the  exercise of  debt
        warrants,  the time,  manner and  place for  such Debt  Securities to be
        authenticated and delivered;
 
   (17) whether and under what circumstances the Operating Partnership will  pay
        additional  amounts  on  such Debt  Securities  in respect  of  any tax,
        assessment or  governmental charge  and, if  so, whether  the  Operating
        Partnership  will have the option to redeem such Debt Securities in lieu
        of making such payment;
 
   (18) with respect to any Debt Securities that provide for optional redemption
        or prepayment upon the occurrence of certain events (such as a change of
        control of the Operating Partnership), (i) the possible effects of  such
        provisions  on the  market price of  the Operating  Partnership's or the
        Company's securities or in deterring  certain mergers, tender offers  or
        other  takeover attempts, and the intention of the Operating Partnership
        to comply with the requirements of Rule 14e-1 under the Exchange Act and
        any other applicable securities laws in connection with such provisions;
        (ii) whether the  occurrence of the  specified events may  give rise  to
        cross-defaults  on  other indebtedness  such that  payment on  such Debt
        Securities may be effectively subordinated;  and (iii) the existence  of
        any limitation on the Operating Partnership's financial or legal ability
        to  repurchase such Debt Securities upon the occurrence of such an event
        (including, if true, the lack of assurance that such a repurchase can be
        effected) and the impact, if any, under the Indenture of such a failure,
        including whether  and  under  what circumstances  such  a  failure  may
        constitute an Event of Default; and
 
   (19) any other terms of such Debt Securities.
 
    The  Debt Securities may  provide for less than  the entire principal amount
thereof to be payable upon declaration  of acceleration of the maturity  thereof
("Original  Issue Discount Securities"). If material or applicable, special U.S.
federal income tax, accounting and  other considerations applicable to  Original
Issue  Discount  Securities  will  be  described  in  the  applicable Prospectus
Supplement.
 
    Except as described under "Merger, Consolidation  or Sale" or as may be  set
forth  in any  Prospectus Supplement, the  Indenture does not  contain any other
provisions that would limit  the ability of the  Operating Partnership to  incur
indebtedness  or that would afford holders  of the Debt Securities protection in
the event  of  (i) a  highly  leveraged  or similar  transaction  involving  the
Operating  Partnership,  the  management  of the  Operating  Partnership  or the
Company,  or   any   affiliate  of   any   such   party,  (ii)   a   change   of
 
                                       6

control, or (iii) a reorganization, restructuring, merger or similar transaction
involving the Operating Partnership that may adversely affect the holders of the
Debt  Securities.  In  addition,  subject to  the  limitations  set  forth under
"Merger, Consolidation or Sale," the  Operating Partnership may, in the  future,
enter into certain transactions, such as the sale of all or substantially all of
its  assets or  the merger or  consolidation of the  Operating Partnership, that
would increase  the  amount  of  the  Operating  Partnership's  indebtedness  or
substantially  reduce or eliminate the Operating Partnership's assets, which may
have an adverse  effect on the  Operating Partnership's ability  to service  its
indebtedness,  including  the  Debt  Securities.  In  addition,  restrictions on
ownership and transfers of  the Company's common stock  and preferred stock  are
designed  to preserve its status as a REIT and, therefore, may act to prevent or
hinder a  change  of  control.  See "Description  of  Common  Stock  --  Certain
Provisions  Affecting Change of Control" and  "Description of Preferred Stock --
Restrictions on  Ownership."  Reference is  made  to the  applicable  Prospectus
Supplement  for information with respect to any deletions from, modifications of
or additions to  the events of  default or covenants  that are described  below,
including  any addition of a covenant or other provision providing event risk or
similar protection.
 
    Reference is made to "-- Certain Covenants" below and to the description  of
any  additional covenants  with respect  to a series  of Debt  Securities in the
applicable  Prospectus  Supplement.  Except   as  otherwise  described  in   the
applicable  Prospectus Supplement, compliance with  such covenants generally may
not be  waived with  respect to  a series  of Debt  Securities by  the Board  of
Directors of the Company as sole general partner of the Operating Partnership or
by  the Trustee unless the Holders of at least a majority in principal amount of
all outstanding Debt Securities of such series consent to such waiver, except to
the extent  that  the  defeasance  and covenant  defeasance  provisions  of  the
Indenture  described under  "-- Discharge,  Defeasance and  Covenant Defeasance"
below apply  to such  series of  Debt Securities.  See "--  Modification of  the
Indenture."
 
DENOMINATIONS, INTEREST, REGISTRATION AND TRANSFER
 
    Unless otherwise described in the applicable Prospectus Supplement, the Debt
Securities  of any series which are registered securities, other than registered
securities issued in global  form (which may be  of any denomination), shall  be
issuable  in denominations of  $1,000 and any integral  multiple thereof and the
Debt Securities which are bearer securities, other than bearer securities issued
in global  form  (which  may be  of  any  denomination), shall  be  issuable  in
denominations of $5,000 (Section 302).
 
    Unless  otherwise  specified in  the  applicable Prospectus  Supplement, the
principal of (and premium, if any) and interest on any series of Debt Securities
will be payable at the corporate trust office of the Trustee, initially  located
at  14 Wall Street, Eighth  Floor, New York, New  York, 10005, provided that, at
the option of  the Operating  Partnership, payment of  interest may  be made  by
check  mailed to the address of the Person entitled thereto as it appears in the
applicable Security Register or by wire transfer  of funds to such Person at  an
account maintained within the United States (Sections 301, 307 and 1002).
 
    Any  interest  not punctually  paid  or duly  provided  for on  any Interest
Payment Date  with  respect  to  a Debt  Security  ("Defaulted  Interest")  will
forthwith  cease to be  payable to the  Holder on the  applicable Regular Record
Date and may either be  paid to the Person in  whose name such Debt Security  is
registered  at the  close of  business on  a special  record date  (the "Special
Record Date") for  the payment of  such Defaulted  Interest to be  fixed by  the
Trustee,  notice whereof shall be given to  the Holder of such Debt Security not
less than 10 days prior to such Special Record Date, or may be paid at any  time
in any other lawful manner, all as more completely described in the Indenture.
 
    Subject  to  certain  limitations  imposed upon  Debt  Securities  issued in
book-entry form, the  Debt Securities  of any  series will  be exchangeable  for
other  Debt Securities  of the  same series  and of  a like  aggregate principal
amount and tenor of  different authorized denominations  upon surrender of  such
Debt  Securities at the corporate trust office of the Trustee referred to above.
In addition, subject to certain limitations imposed upon Debt Securities  issued
in  book-entry form, the  Debt Securities of  any series may  be surrendered for
registration of transfer thereof  at the corporate trust  office of the  Trustee
referred to above.
 
                                       7

Every  Debt Security surrendered for registration  of transfer or exchange shall
be duly endorsed or accompanied by a written instrument of transfer. No  service
charge  will be made  for any registration  of transfer or  exchange of any Debt
Securities, but the Trustee or the Operating Partnership may require payment  of
a  sum  sufficient to  cover any  tax  or other  governmental charge  payable in
connection therewith  (Section 305).  If  the applicable  Prospectus  Supplement
refers  to any transfer agent (in  addition to the Trustee) initially designated
by the Operating Partnership with respect to any series of Debt Securities,  the
Operating  Partnership  may at  any  time rescind  the  designation of  any such
transfer agent  or approve  a change  in  the location  through which  any  such
transfer  agent  acts, except  that Operating  Partnership  will be  required to
maintain a  transfer  agent  in each  place  of  payment for  such  series.  The
Operating  Partnership may at any time designate additional transfer agents with
respect to any series of Debt Securities (Section 1002).
 
    Neither the Operating Partnership nor the  Trustee shall be required (i)  to
issue,  register the  transfer of  or exchange  any Debt  Security if  such Debt
Security may be among those selected for redemption during a period beginning at
the opening of business 15  days before selection of  the Debt Securities to  be
redeemed  and ending at the close of business on (A) if such Debt Securities are
issuable only as Registered Securities, the  day of the mailing of the  relevant
notice  of redemption  and (B)  if such Debt  Securities are  issuable as Bearer
Securities, the  day  of  the  first  publication  of  the  relevant  notice  of
redemption  or,  if  such  Debt  Securities  are  also  issuable  as  Registered
Securities and there is  no publication, the mailing  of the relevant notice  of
redemption,  or  (ii) to  register the  transfer of  or exchange  any Registered
Security so selected for redemption in whole or in part, except, in the case  of
any  Registered Security to be  redeemed in part, the  portion thereof not to be
redeemed, or (iii) to  exchange any Bearer Security  so selected for  redemption
except that such a Bearer Security may be exchanged for a Registered Security of
that  series and  like tenor,  PROVIDED that  such Registered  Security shall be
simultaneously surrendered  for  redemption,  or (iv)  to  issue,  register  the
transfer of or exchange any Security which has been surrendered for repayment at
the  option of the Holder, except the portion, if any, of such Debt Security not
to be so repaid (Section 305).
 
MERGER, CONSOLIDATION OR SALE
 
    The Operating Partnership may consolidate with, or sell, lease or convey all
or substantially all of its assets to, or merge with or into, any other  entity,
provided  that (a) the Operating Partnership  shall be the continuing entity, or
the successor entity  (if other  than the  Operating Partnership)  formed by  or
resulting from any such consolidation or merger or which shall have received the
transfer  of such assets shall expressly assume payment of the principal of (and
premium, if  any) and  interest  on all  the Debt  Securities  and the  due  and
punctual  performance  and observance  of all  of  the covenants  and conditions
contained in  the  Indenture;  (b)  immediately  after  giving  effect  to  such
transaction  and treating  any indebtedness which  becomes an  obligation of the
Operating Partnership  or any  Subsidiary as  a result  thereof as  having  been
incurred  by the Operating  Partnership or such  Subsidiary at the  time of such
transaction, no Event of Default under the Indenture, and no event which,  after
notice  or the lapse  of time, or both,  would become such  an Event of Default,
shall have occurred  and be  continuing; and  (c) an  officer's certificate  and
legal  opinion  covering  such  conditions shall  be  delivered  to  the Trustee
(Sections 801 and 803).
 
CERTAIN COVENANTS
 
    EXISTENCE.  Except as permitted  under "Merger, Consolidation or Sale,"  the
Operating Partnership is required to do or cause to be done all things necessary
to  preserve  and  keep in  full  force  and effect  its  existence,  rights and
franchises; PROVIDED,  HOWEVER,  that the  Operating  Partnership shall  not  be
required  to  preserve  any  right  or  franchise  if  it  determines  that  the
preservation thereof is no longer desirable  in the conduct of its business  and
that  the loss  thereof is  not disadvantageous in  any material  respect to the
Holders of the Debt Securities (Section 1007).
 
    MAINTENANCE OF PROPERTIES.  The  Operating Partnership is required to  cause
all  of its material properties used or useful in the conduct of its business or
the business of  any Subsidiary  to be maintained  and kept  in good  condition,
repair  and working order and supplied with all necessary equipment and to cause
to be  made  all  necessary repairs,  renewals,  replacements,  betterments  and
improvements thereof, all as in the judgment
 
                                       8

of the Operating Partnership may be necessary so that the business carried on in
connection  therewith may be properly and advantageously conducted at all times;
PROVIDED, HOWEVER, that the Operating Partnership and its Subsidiaries shall not
be prevented  from selling  or otherwise  disposing for  value their  respective
properties in the ordinary course of business (Section 1008).
 
    INSURANCE.   The  Operating Partnership is  required to, and  is required to
cause each of its Subsidiaries to, keep all of its insurable properties  insured
against  loss or damage at  least equal to their  then full insurable value with
financially sound and reputable insurance companies (Section 1009).
 
    PAYMENT OF TAXES AND OTHER CLAIMS.  The Operating Partnership is required to
pay or discharge or cause to be paid or discharged, before the same shall become
delinquent, (i)  all  taxes,  assessments and  governmental  charges  levied  or
imposed  upon it or  any Subsidiary or  upon its income,  profits or property or
that of any  Subsidiary, and  (ii) all lawful  claims for  labor, materials  and
supplies  which, if unpaid, might by law become  a lien upon the property of the
Operating Partnership or any Subsidiary;  PROVIDED, HOWEVER, that the  Operating
Partnership  shall not be  required to pay or  discharge or cause  to be paid or
discharged any such tax, assessment, charge or claim whose amount, applicability
or validity is being contested in good faith by appropriate proceedings (Section
1010).
 
    PROVISION OF FINANCIAL INFORMATION.  The Holders of Debt Securities will  be
provided  with  copies  of  the  annual reports  and  quarterly  reports  of the
Operating Partnership. Whether or  not the Operating  Partnership is subject  to
Section  13 or 15(d) of the Exchange Act  and for so long as any Debt Securities
are outstanding, the Operating Partnership  will, to the extent permitted  under
the  Exchange Act, be required  to file with the  Commission the annual reports,
quarterly reports and other documents which the Operating Partnership would have
been required to file with the Commission  pursuant to such Section 13 or  15(d)
(the  "Financial Statements") if the Operating Partnership were so subject, such
documents to be filed with  the Commission on or  prior to the respective  dates
(the "Required Filing Dates") by which the Operating Partnership would have been
required so to file such documents if the Operating Partnership were so subject.
The  Operating Partnership  will also in  any event  (x) within 15  days of each
Required Filing Date (i) transmit by mail to all Holders of Debt Securities,  as
their  names and addresses appear in the Security Register, without cost to such
Holders, copies of the annual reports and quarterly reports which the  Operating
Partnership  would have  been required to  file with the  Commission pursuant to
Section 13  or 15(d)  of the  Exchange  Act if  the Operating  Partnership  were
subject  to such Sections  and (ii) file  with the Trustee  copies of the annual
reports, quarterly reports and other  documents which the Operating  Partnership
would  have been required to file with  the Commission pursuant to Section 13 or
15(d) of the  Exchange Act  if the Operating  Partnership were  subject to  such
Sections  and (y) if filing such documents by the Operating Partnership with the
Commission is  not  permitted under  the  Exchange Act,  promptly  upon  written
request  and payment of the reasonable  cost of duplication and delivery, supply
copies of such documents to any prospective Holder (Section 1011).
 
    ADDITIONAL  COVENANTS.    Any  additional  or  different  covenants  of  the
Operating  Partnership with respect to any series of Debt Securities will be set
forth in the Prospectus Supplement relating thereto.
 
EVENTS OF DEFAULT, NOTICE AND WAIVER
 
    The Indenture provides  that the  following events are  "Events of  Default"
with respect to any series of Debt Securities issued thereunder: (a) default for
30  days in the payment  of any installment of interest  on any Debt Security of
such series; (b) default in the payment of the principal of (or premium, if any,
on) any Debt Security of such series at its maturity; (c) default in making  any
sinking  fund payment  as required  for any  Debt Security  of such  series; (d)
default in the performance  of any other covenant  of the Operating  Partnership
contained  in the Indenture (other than a covenant added to the Indenture solely
for the benefit of a series of Debt Securities issued thereunder other than such
series), such  default having  continued for  60 days  after written  notice  as
provided  in the Indenture; (e) default in the payment of an aggregate principal
amount exceeding  $5,000,000 of  any evidence  of recourse  indebtedness of  the
Operating Partnership or any
 
                                       9

mortgage,  indenture or other instrument under which such indebtedness is issued
or by which such indebtedness is secured, such default having occurred after the
expiration  of  any  applicable  grace   period  and  having  resulted  in   the
acceleration of the maturity of such indebtedness, but only if such indebtedness
is not discharged or such acceleration is not rescinded or annulled; (f) certain
events  of bankruptcy, insolvency  or reorganization, or  court appointment of a
receiver, liquidator or trustee of the Operating Partnership or any  Significant
Subsidiary  or any  of their  respective property;  and (g)  any other  Event of
Default provided with  respect to a  particular series of  Debt Securities.  The
term  "Significant Subsidiary" means each  significant subsidiary (as defined in
Regulation  S-X  promulgated  under  the   Securities  Act)  of  the   Operating
Partnership.
 
    If  an Event of Default under the  Indenture with respect to Debt Securities
of any series at the  time Outstanding occurs and  is continuing, then in  every
such case the Trustee or the Holders of not less than 25% in principal amount of
the  Outstanding Debt Securities of that series may declare the principal amount
(or, if  the  Debt  Securities  of  that  series  are  Original  Issue  Discount
Securities or Indexed Securities, such portion of the principal amount as may be
specified  in the terms thereof) of all of the Debt Securities of that series to
be due  and payable  immediately  by written  notice  thereof to  the  Operating
Partnership  (and to the Trustee if given  by the Holders). However, at any time
after such a declaration of acceleration with respect to Debt Securities of such
series (or of all Debt Securities  then Outstanding under the Indenture, as  the
case  may be) has been made, but before  a judgment or decree for payment of the
money due has  been obtained  by the  Trustee, the Holders  of not  less than  a
majority  in principal amount of Outstanding  Debt Securities of such series (or
of all Debt Securities then Outstanding under the Indenture, as the case may be)
may rescind and annul such declaration and its consequences if (a) the Operating
Partnership shall  have  deposited  with the  applicable  Trustee  all  required
payments  of the  principal of (and  premium, if  any) and interest  on the Debt
Securities of such series (or of all Debt Securities then Outstanding under  the
Indenture,  as the case may be),  plus certain fees, expenses, disbursements and
advances of  the  Trustee  and  (b)  all  Events  of  Default,  other  than  the
non-payment  of  accelerated principal  of  (or specified  portion  thereof), or
premium (if any) or interest  on the Debt Securities of  such series (or of  all
Debt  Securities then Outstanding under the Indenture,  as the case may be) have
been cured or waived as provided  in the Indenture (Section 502). The  Indenture
also  provides that the Holders of not  less than a majority in principal amount
of the Outstanding Debt Securities of any series (or of all Debt Securities then
Outstanding under the Indenture, as the case may be) may waive any past  default
with  respect to such series  and its consequences, except  a default (x) in the
payment of  the principal  of  (or premium,  if any)  or  interest on  any  Debt
Security  or such series or (y) in  respect of a covenant or provision contained
in the Indenture that cannot be modified  or amended without the consent of  the
Holder of each Outstanding Debt Security affected thereby (Section 513).
 
    The  Trustee  will  be  required  to give  notice  to  the  Holders  of Debt
Securities within 90 days of a  default under the Indenture unless such  default
has  been  cured or  waived; PROVIDED,  HOWEVER, that  the Trustee  may withhold
notice to the  Holders of  any series  of Debt  Securities of  any default  with
respect  to such series (except a default in the payment of the principal of (or
premium, if any)  or interest  on any  Debt Security of  such series  or in  the
payment  of any sinking fund installment in respect of any Debt Security of such
series)  if  specified  Responsible  Officers  of  the  Trustee  consider   such
withholding to be in the interest of such Holders (Section 601).
 
    The  Indenture provides that no Holders of Debt Securities of any series may
institute any proceedings, judicial or otherwise, with respect to the  Indenture
or  for any remedy thereunder, except in the case of failure of the Trustee, for
60 days, to act after it has received a written request to institute proceedings
in respect of  an Event  of Default from  the Holders  of not less  than 25%  in
principal  amount of the Outstanding Debt Securities  of such series, as well as
an offer  of  indemnity  reasonably  satisfactory  to  it  (Section  507).  This
provision  will  not  prevent,  however,  any  holder  of  Debt  Securities from
instituting suit  for  the enforcement  of  payment  of the  principal  of  (and
premium,  if any)  and interest  on such Debt  Securities at  the respective due
dates thereof (Section 508).
 
                                       10

    Subject to provisions  in the Indenture  relating to its  duties in case  of
default,  the Trustee is  under no obligation  to exercise any  of its rights or
powers under the Indenture  at the request  or direction of  any Holders of  any
series  of Debt  Securities then  Outstanding under  the Indenture,  unless such
Holders shall  have offered  to the  Trustee thereunder  reasonable security  or
indemnity  (Section 602). The Holders  of not less than  a majority in principal
amount of  the  Outstanding  Debt Securities  of  any  series (or  of  all  Debt
Securities  then Outstanding under the Indenture, as the case may be) shall have
the right to direct the time, method and place of conducting any proceeding  for
any  remedy  available to  the  Trustee, or  of  exercising any  trust  or power
conferred upon  the Trustee.  However,  the Trustee  may  refuse to  follow  any
direction  which is in conflict with any law or the Indenture, which may involve
the Trustee in  personal liability  or which may  be unduly  prejudicial to  the
holders of Debt Securities of such series not joining therein (Section 512).
 
    Within  120  days  after  the  close  of  each  fiscal  year,  the Operating
Partnership must deliver to the Trustee a certificate, signed by one of  several
specified  officers  of the  Company, stating  whether or  not such  officer has
knowledge of any default  under the Indenture and,  if so, specifying each  such
default and the nature and status thereof.
 
MODIFICATION OF THE INDENTURE
 
    Modifications  and amendments of the Indenture  will be permitted to be made
only with the consent of  the Holders of not less  than a majority in  principal
amount  of  all  Outstanding  Debt  Securities  or  series  of  Outstanding Debt
Securities which  are  affected by  such  modification or  amendment;  PROVIDED,
HOWEVER,  that no such modification or amendment may, without the consent of the
Holder of  each such  Debt  Security affected  thereby,  (a) change  the  Stated
Maturity of the principal of, or premium (if any) or any installment of interest
on,  any such Debt Security; (b) reduce the  principal amount of, or the rate or
amount of interest on, or  any premium payable on  redemption of, any such  Debt
Security,  or  reduce the  amount  of principal  of  an Original  Issue Discount
Security that would be due and  payable upon declaration of acceleration of  the
maturity  thereof or  would be provable  in bankruptcy, or  adversely affect any
right of repayment of the holder of any such Debt Security; (c) change the place
of payment, or the coin  or currency, for payment  of principal of, premium,  if
any,  or interest on any  such Debt Security; (d)  impair the right to institute
suit for the  enforcement of any  payment on or  with respect to  any such  Debt
Security;  (e) reduce the above-stated percentage of outstanding Debt Securities
of any series necessary  to modify or amend  the Indenture, to waive  compliance
with  certain provisions thereof or certain defaults and consequences thereunder
or to reduce the quorum  or voting requirements set  forth in the Indenture;  or
(f)  modify any of the foregoing provisions or any of the provisions relating to
the waiver of certain past defaults or certain covenants, except to increase the
required percentage  to effect  such action  or to  provide that  certain  other
provisions  may not be modified  or waived without the  consent of the Holder of
such Debt Security (Section 902).
 
    The Indenture  provides that  the Holders  of not  less than  a majority  in
principal  amount of a series  of Outstanding Debt Securities  have the right to
waive compliance by the Operating Partnership with certain covenants relating to
such series of Debt Securities in the Indenture (Section 1014).
 
    Modifications and amendments of the Indenture  will be permitted to be  made
by  the Operating Partnership and the Trustee  without the consent of any Holder
of Debt  Securities for  any of  the  following purposes:  (i) to  evidence  the
succession  of another Person to the  Operating Partnership as obligor under the
Indenture; (ii) to  add to the  covenants of the  Operating Partnership for  the
benefit  of the Holders of all or any  series of Debt Securities or to surrender
any right or power  conferred upon the Operating  Partnership in the  Indenture;
(iii)  to add Events  of Default for  the benefit of  the Holders of  all or any
series of Debt Securities; (iv) to add or change any provisions of the Indenture
to facilitate  the  issuance  of,  or  to  liberalize  certain  terms  of,  Debt
Securities  in bearer  form, or  to permit  or facilitate  the issuance  of Debt
Securities in uncertificated form, PROVIDED that such action shall not adversely
affect the interests of the Holders of the Debt Securities of any series in  any
material  respect; (v) to  change or eliminate any  provisions of the Indenture,
PROVIDED that any such  change or elimination shall  become effective only  when
there  are no  Debt Securities Outstanding  of any series  created prior thereto
which are entitled to the benefit of such provision;
 
                                       11

(vi) to secure the Debt Securities; (vii) to establish the form or terms of Debt
Securities of any series; (viii) to provide for the acceptance of appointment by
a successor Trustee  or facilitate the  administration of the  trusts under  the
Indenture  by  more than  one Trustee;  (ix)  to cure  any ambiguity,  defect or
inconsistency in the Indenture,  PROVIDED that such  action shall not  adversely
affect the interests of Holders of Debt Securities of any series in any material
respect;  or (x)  to supplement any  of the  provisions of the  Indenture to the
extent necessary to permit or facilitate defeasance and discharge of any  series
of  such Debt Securities,  PROVIDED that such action  shall not adversely affect
the interests  of the  Holders  of the  Debt Securities  of  any series  in  any
material respect (Section 901).
 
    The  Indenture  provides  that in  determining  whether the  Holders  of the
requisite principal amount of Outstanding Debt Securities of a series have given
any  request,  demand,  authorization,  direction,  notice,  consent  or  waiver
thereunder  or  whether a  quorum is  present at  a meeting  of Holders  of Debt
Securities, (i) the principal amount of an Original Issue Discount Security that
shall be deemed to be Outstanding shall  be the amount of the principal  thereof
that  would  be  due and  payable  as of  the  date of  such  determination upon
declaration of acceleration of the  maturity thereof, (ii) the principal  amount
of  a  Debt Security  denominated in  a  foreign currency  that shall  be deemed
Outstanding shall be the  U.S. dollar equivalent, determined  on the issue  date
for  such Debt Security, of the principal amount (or, in the case of an Original
Issue Discount Security, the  U.S. dollar equivalent on  the issue date of  such
Debt  Security of  the amount  determined as provided  in (i)  above), (iii) the
principal amount of an Indexed Security  that shall be deemed Outstanding  shall
be  the principal  face amount  of such  Indexed Security  at original issuance,
unless otherwise provided with respect to such Indexed Security pursuant to  the
Indenture,  and (iv) Debt  Securities owned by the  Operating Partnership or any
other obligor  upon  the Debt  Securities  or  any affiliate  of  the  Operating
Partnership or of such other obligor shall be disregarded.
 
    The  Indenture contains provisions for convening  meetings of the Holders of
Debt Securities of a series  (Section 1501). A meeting  will be permitted to  be
called  at any  time by the  Trustee, and  also, upon request,  by the Operating
Partnership or  the  holders  of  at  least  10%  in  principal  amount  of  the
Outstanding  Debt Securities of such series, in  any such case upon notice given
as provided in the Indenture (Section 1502). Except for any consent that must be
given by the Holder of each Debt Security affected by certain modifications  and
amendments  of the Indenture, any resolution presented at a meeting or adjourned
meeting duly reconvened at  which a quorum  is present will  be permitted to  be
adopted by the affirmative vote of the Holders of a majority in principal amount
of  the Outstanding  Debt Securities  of that  series; PROVIDED,  HOWEVER, that,
except as referred to above, any resolution with respect to any request, demand,
authorization, direction, notice, consent,  waiver or other  action that may  be
made,  given or taken  by the Holders  of a specified  percentage, which is less
than a majority,  in principal amount  of the Outstanding  Debt Securities of  a
series may be adopted at a meeting or adjourned meeting duly reconvened at which
a  quorum is present  by the affirmative  vote of the  Holders of such specified
percentage in  principal  amount of  the  Outstanding Debt  Securities  of  that
series.  Any resolution passed  or decision taken  at any meeting  of Holders of
Debt Securities of any series duly held in accordance with the Indenture will be
binding on all  Holders of Debt  Securities of  that series. The  quorum at  any
meeting  called to adopt  a resolution, and  at any reconvened  meeting, will be
Persons  holding  or  representing  a  majority  in  principal  amount  of   the
Outstanding  Debt Securities of a series;  PROVIDED, HOWEVER, that if any action
is to be taken at such meeting with respect to a consent or waiver which may  be
given by the Holders of not less than a specified percentage in principal amount
of  the  Outstanding  Debt  Securities  of  a  series,  the  Persons  holding or
representing such specified  percentage in principal  amount of the  Outstanding
Debt Securities of such series will constitute a quorum (Section 1504).
 
    Notwithstanding  the foregoing provisions, if any action is to be taken at a
meeting of Holders of Debt Securities of any series with respect to any request,
demand, authorization, direction, notice, consent,  waiver or other action  that
the Indenture expressly provides may be made, given or taken by the Holders of a
specified  percentage  in principal  amount of  all Outstanding  Debt Securities
affected thereby, or of the  Holders of such series  and one or more  additional
series: (i) there shall be no minimum quorum requirement
 
                                       12

for  such  meeting  and  (ii)  the  principal  amount  of  the  Outstanding Debt
Securities  of  such  series  that  vote  in  favor  of  such  request,  demand,
authorization, direction, notice, consent, waiver or other action shall be taken
into  account  in  determining  whether  such  request,  demand,  authorization,
direction, notice, consent, waiver or other action has been made, given or taken
under the Indenture (Section 1504).
 
DISCHARGE, DEFEASANCE AND COVENANT DEFEASANCE
 
    The Operating Partnership  may discharge certain  obligations to Holders  of
any  series  of Debt  Securities that  have  not already  been delivered  to the
Trustee for cancellation  and that either  have become due  and payable or  will
become  due and payable within one year  (or scheduled for redemption within one
year) by  irrevocably depositing  with  the Trustee,  in  trust, funds  in  such
currency  or  currencies,  currency  unit  or  units  or  composite  currency or
currencies in which such Debt Securities are payable in an amount sufficient  to
pay the entire indebtedness on such Debt Securities in respect of principal (and
premium,  if  any)  and interest  to  the date  of  such deposit  (if  such Debt
Securities have become due and payable) or to the Stated Maturity or  Redemption
Date, as the case may be (Sections 1401 and 1404).
 
    The  Indenture provides that, if the provisions of Article Fourteen are made
applicable to the Debt  Securities of or within  any series pursuant to  Section
301  of the Indenture, the Operating Partnership may elect either (a) to defease
and be  discharged  from any  and  all obligations  with  respect to  such  Debt
Securities  (except for the  obligation to pay additional  amounts, if any, upon
the occurrence of certain events of tax, assessment or governmental charge  with
respect  to payments on such Debt Securities and the obligations to register the
transfer or exchange of such Debt Securities, to replace temporary or mutilated,
destroyed, lost or stolen  Debt Securities, to maintain  an office or agency  in
respect  of  such Debt  Securities  and to  hold  moneys for  payment  in trust)
("defeasance") (Section 1402) or  (b) to be released  from its obligations  with
respect  to such Debt Securities under Sections  1004 to 1011, inclusive, of the
Indenture (including the restrictions  described under "Certain Covenants")  and
its  obligations with respect to any other  covenant, and any omission to comply
with such obligations shall not constitute a default or an Event of Default with
respect to  such  Debt Securities  ("covenant  defeasance") (Section  1403),  in
either  case upon the irrevocable deposit  by the Operating Partnership with the
Trustee, in trust, of an amount,  in such currency or currencies, currency  unit
or  units or composite currency or currencies  in which such Debt Securities are
payable at Stated  Maturity, or  Government Obligations (as  defined below),  or
both,  applicable to such Debt Securities which through the scheduled payment of
principal and interest in accordance with  their terms will provide money in  an
amount  sufficient to pay the principal of (and premium, if any) and interest on
such Debt  Securities, and  any  mandatory sinking  fund or  analogous  payments
thereon, on the scheduled due dates therefor.
 
    Such  a  trust will  only be  permitted  to be  established if,  among other
things, the Operating  Partnership has delivered  to the Trustee  an Opinion  of
Counsel  (as specified in the Indenture) to  the effect that the Holders of such
Debt Securities will not recognize income, gain or loss for U.S. federal  income
tax  purposes as a result of such  defeasance or covenant defeasance and will be
subject to U.S. federal income tax on  the same amounts, in the same manner  and
at  the same times  as would have been  the case if  such defeasance or covenant
defeasance had  not  occurred, and  such  Opinion of  Counsel,  in the  case  of
defeasance,  must refer to  and be based  upon a ruling  of the Internal Revenue
Service or a change in applicable United States federal income tax law occurring
after the date of the Indenture (Section 1404).
 
    "Government Obligations" means securities  which are (i) direct  obligations
of  the United  States of  America or  the government  which issued  the foreign
currency in which the  Debt Securities of a  particular series are payable,  for
the payment of which its full faith and credit is pledged or (ii) obligations of
a  person controlled or supervised by and acting as an agency or instrumentality
of the United  States of  America or such  government which  issued the  foreign
currency in which the Debt Securities of such series are payable, the payment of
which is unconditionally guaranteed as a full faith and credit obligation by the
United  States of America or  such other government, which,  in either case, are
not callable or redeemable at the option  of the issuer thereof, and shall  also
include  a depository  receipt issued  by a bank  or trust  company as custodian
 
                                       13

with respect to any such Government Obligation or a specific payment of interest
on or principal of any such Government Obligation held by such custodian for the
account of the holder of a depository receipt, PROVIDED that (except as required
by law) such custodian is not authorized  to make any deduction from the  amount
payable to the holder of such depository receipt from any amount received by the
custodian  in respect  of the Government  Obligation or the  specific payment of
interest on  or  principal  of  the  Government  Obligation  evidenced  by  such
depository receipt.
 
    Unless  otherwise provided in the applicable Prospectus Supplement, if after
the Operating Partnership has deposited  funds and/or Government Obligations  to
effect  defeasance or covenant defeasance with respect to Debt Securities of any
series, (a) the Holder  of a Debt  Security of such series  is entitled to,  and
does,  elect pursuant  to the Indenture  or the  terms of such  Debt Security to
receive payment in a  currency, currency unit or  composite currency other  than
that  in which such deposit  has been made in respect  of such Debt Security, or
(b) a Conversion  Event (as defined  below) occurs in  respect of the  currency,
currency  unit or composite  currency in which  such deposit has  been made, the
indebtedness represented by such Debt Security shall be deemed to have been, and
will be, fully discharged and satisfied through the payment of the principal  of
(and  premium, if any) and interest on such Debt Security as they become due out
of the proceeds yielded by converting the amount so deposited in respect of such
Debt Security into the  currency, currency unit or  composite currency in  which
such  Debt  Security  becomes payable  as  a  result of  such  election  or such
Conversion Event  based  on the  applicable  market exchange  rate.  "Conversion
Event"  means the cessation of use of (i) a currency, currency unit or composite
currency both by the  government of the country  which issued such currency  and
for   the  settlement  of  transactions  by  a  central  bank  or  other  public
institutions of or within the international banking community, (ii) the ECU both
within the European Monetary  System and for the  settlement of transactions  by
public  institutions of or  within the European Community  or (iii) any currency
unit or composite currency other than the ECU for the purposes for which it  was
established.  Unless otherwise provided in the applicable Prospectus Supplement,
all payments of  principal of (and  premium, if  any) and interest  on any  Debt
Security  that is payable  in a foreign currency  that ceases to  be used by its
government of issuance shall be made in U.S. dollars.
 
    In the  event the  Operating Partnership  effects covenant  defeasance  with
respect  to any Debt  Securities and such  Debt Securities are  declared due and
payable because of the occurrence of any  Event of Default other than the  Event
of  Default described in clause (d) under "Events of Default, Notice and Waiver"
with respect  to Sections  1004  to 1011,  inclusive,  of the  Indenture  (which
sections  would no longer be applicable to such Debt Securities) or described in
clause (g) under  "Events of  Default, Notice and  Waiver" with  respect to  any
other  covenant as to  which there has  been covenant defeasance,  the amount in
such currency, currency unit or composite currency in which such Debt Securities
are payable, and  Government Obligations on  deposit with the  Trustee, will  be
sufficient  to pay  amounts due  on such  Debt Securities  at the  time of their
Stated Maturity  but may  not be  sufficient to  pay amounts  due on  such  Debt
Securities at the time of the acceleration resulting from such Event of Default.
However,  the Operating Partnership would remain  liable to make payment of such
amounts due at the time of acceleration.
 
    The applicable Prospectus Supplement may further describe the provisions, if
any,  permitting  such   defeasance  or  covenant   defeasance,  including   any
modifications  to  the  provisions described  above,  with respect  to  the Debt
Securities of or within a particular series.
 
NO CONVERSION RIGHTS
 
    The Debt Securities  will not be  convertible into or  exchangeable for  any
capital stock of the Company or equity interest in the Operating Partnership.
 
GLOBAL SECURITIES
 
    The  Debt Securities of  a series may be  issued in whole or  in part in the
form of one  or more global  securities (the "Global  Securities") that will  be
deposited  with, or on behalf of,  a depositary (the "Depositary") identified in
the applicable Prospectus Supplement relating to such series. Global  Securities
may be
 
                                       14

issued  in either registered or bearer form and in either temporary or permanent
form. The specific terms of the depositary arrangement with respect to a  series
of  Debt Securities  will be described  in the  applicable Prospectus Supplement
relating to such series.

    Unless otherwise specified in the Prospectus Supplement, the Preferred Stock
will, with respect to dividend  rights and rights upon liquidation,  dissolution
or winding up of the Company, rank (i) senior to all classes or series of Common
Stock  of  the Company,  and to  all  equity securities  ranking junior  to such
Preferred Stock;  (ii) on  a parity  with all  equity securities  issued by  the
Company the terms of which specifically provide that such equity securities rank
on  a parity with the Preferred Stock; and (iii) junior to all equity securities
issued by the Company the terms  of which specifically provide that such  equity
securities rank senior to the Preferred Stock. The term "equity securities" does
not include convertible debt securities.
 
DIVIDENDS
 
    Holders  of the Preferred Stock of each  series will be entitled to receive,
when, as and if declared by the board of directors of the Company, out of assets
of the Company legally available for  payment, cash dividends at such rates  and
on such dates as will be set forth in the applicable Prospectus Supplement. Each
such  dividend shall be payable to holders of record as they appear on the share
transfer books of  the Company on  such record dates  as shall be  fixed by  the
board of directors of the Company.
 
    Dividends  on  any  series  of  the Preferred  Stock  may  be  cumulative or
non-cumulative, as provided in the applicable Prospectus Supplement.  Dividends,
if  cumulative, will  be cumulative  from and  after the  date set  forth in the
applicable Prospectus Supplement. If the board of directors of the Company fails
to declare a dividend payable  on a dividend payment date  on any series of  the
Preferred Stock for which dividends are non-cumulative, then the holders of such
series  of  the Preferred  Stock will  have no  right to  receive a  dividend in
respect of the  dividend period ending  on such dividend  payment date, and  the
Company  will have no  obligation to pay  the dividend accrued  for such period,
whether or  not dividends  on such  series are  declared payable  on any  future
dividend payment date.
 
    If  Preferred  Stock of  any  series is  outstanding,  no dividends  will be
declared or paid or set apart for payment on any capital stock of the Company of
any other series ranking,  as to dividends,  on a parity with  or junior to  the
Preferred  Stock of  such series  for any  period unless  (i) if  such series of
Preferred Stock has a cumulative  dividend, full cumulative dividends have  been
or  contemporaneously are declared and paid or declared and a sum sufficient for
the payment thereof set apart  for such payment on  the Preferred Stock of  such
series  for all past  dividend periods and  the then current  dividend period or
(ii) if such series of Preferred Stock does not have a cumulative dividend, full
dividends for the then  current dividend period  have been or  contemporaneously
are  declared and paid or declared and  a sum sufficient for the payment thereof
set apart for such payment on the Preferred Stock of such series. When dividends
are not paid in full (or  a sum sufficient for such  full payment is not so  set
apart)  upon Preferred Stock of any series and the shares of any other series of
Preferred Stock ranking on a parity as to dividends with the Preferred Stock  of
such  series, all dividends declared upon Preferred Stock of such series and any
other series of Preferred Stock  ranking on a parity  as to dividends with  such
Preferred  Stock shall  be declared  pro rata  so that  the amount  of dividends
declared per share of Preferred  Stock of such series  and such other series  of
Preferred  Stock  shall in  all cases  bear to  each other  the same  ratio that
accrued dividends per share on the  Preferred Stock of such series (which  shall
not   include  any  accumulation  in  respect  of  unpaid  dividends  for  prior
 
                                       16

dividend periods if such  Preferred Stock does not  have a cumulative  dividend)
and such other series of Preferred Stock bear to each other. No interest, or sum
of  money  in lieu  of interest,  shall be  payable in  respect of  any dividend
payment or payments on Preferred Stock of such series which may be in arrears.
 
    Except as provided  in the  immediately preceding paragraph,  unless (i)  if
such  series  of  Preferred Stock  has  a cumulative  dividend,  full cumulative
dividends on the Preferred Stock of  such series have been or  contemporaneously
are  declared and paid or declared and  a sum sufficient for the payment thereof
set apart  for  payment for  all  past dividend  periods  and the  then  current
dividend  period, and  (ii) if such  series of  Preferred Stock does  not have a
cumulative dividend, full dividends on the  Preferred Stock of such series  have
been or contemporaneously are declared and paid or declared and a sum sufficient
for  the payment  thereof set  apart for payment  for the  then current dividend
period, no dividends  (other than  in shares of  Common Stock  or other  capital
shares  ranking junior to the Preferred Stock of such series as to dividends and
upon liquidation) shall be declared  or paid or set  aside for payment or  other
distribution  shall be  declared or  made upon  the Common  Stock, or  any other
capital shares  of  the Company  ranking  junior to  or  on a  parity  with  the
Preferred  Stock of such series  as to dividends or  upon liquidation, nor shall
any shares of Common Stock, or any  other capital shares of the Company  ranking
junior to or on a parity with the Preferred Stock of such series as to dividends
or  upon  liquidation  be  redeemed, purchased  or  otherwise  acquired  for any
consideration (or any moneys be paid to or made available for a sinking fund for
the redemption of any such shares) by the Company (except by conversion into  or
exchange for other capital shares of the Company ranking junior to the Preferred
Stock of such series as to dividends and upon liquidation).
 
REDEMPTION
 
    If  so provided in the applicable Prospectus Supplement, the Preferred Stock
will be  subject to  mandatory redemption  or redemption  at the  option of  the
Company, as a whole or in part, in each case upon the terms, at the times and at
the redemption prices set forth in such Prospectus Supplement.
 
    The  Prospectus Supplement relating  to a series of  Preferred Stock that is
subject to  mandatory redemption  will  specify the  number  of shares  of  such
Preferred  Stock that shall be  redeemed by the Company  in each year commencing
after a date to be specified, at  a redemption price per share to be  specified,
together with an amount equal to all accrued and unpaid dividends thereon (which
shall  not, if such Preferred Stock does not have a cumulative dividend, include
any accumulation in respect of unpaid  dividends for prior dividend periods)  to
the  date of redemption.  The redemption price  may be payable  in cash or other
property,  as  specified  in  the  applicable  Prospectus  Supplement.  If   the
redemption  price for Preferred Stock of any series is payable only from the net
proceeds of the issuance  of capital shares  of the Company,  the terms of  such
Preferred  Stock may  provide that,  if no such  capital shares  shall have been
issued or to the extent the net  proceeds from any issuance are insufficient  to
pay  in full the aggregate redemption price then due, such Preferred Stock shall
automatically and mandatorily be converted into the applicable capital shares of
the Company  pursuant  to  conversion provisions  specified  in  the  applicable
Prospectus Supplement.
 
    Notwithstanding  the foregoing, unless (i) if such series of Preferred Stock
has a cumulative dividend, full cumulative dividends on all shares of any series
of Preferred Stock shall have been or contemporaneously are declared and paid or
declared and a sum sufficient for the payment thereof set apart for payment  for
all past dividend periods and the then current dividend period, and (ii) if such
series of Preferred Stock does not have a cumulative dividend, full dividends of
the  Preferred Stock of  any series have been  or contemporaneously are declared
and paid or declared and a sum sufficient for the payment thereof set apart  for
payment  for  the then  current  dividend period,  no  shares of  any  series of
Preferred Stock shall be redeemed unless all outstanding Preferred Stock of such
series is simultaneously redeemed; PROVIDED,  HOWEVER, that the foregoing  shall
not  prevent the purchase  or acquisition of  Preferred Stock of  such series to
preserve the REIT status of  the Company or pursuant  to a purchase or  exchange
offer  made on the same  terms to holders of  all outstanding Preferred Stock of
such   series.    In    addition,    unless    (i)    if    such    series    of
 
                                       17

Preferred  Stock has  a cumulative  dividend, full  cumulative dividends  on all
outstanding  shares   of  any   series   of  Preferred   Stock  have   been   or
contemporaneously are declared and paid or declared and a sum sufficient for the
payment  thereof set apart  for payment for  all past dividends  periods and the
then current dividend period,  and (ii) if such  series of Preferred Stock  does
not  have a cumulative  dividend, full dividends  on the Preferred  Stock of any
series have been or  contemporaneously are declared and  paid or declared and  a
sum  sufficient  for the  payment thereof  set  apart for  payment for  the then
current dividend period,  the Company  shall not purchase  or otherwise  acquire
directly  or indirectly any shares of Preferred  Stock of such series (except by
conversion into or exchange for capital shares of the Company ranking junior  to
the  Preferred  Stock of  such  series as  to  dividends and  upon liquidation);
PROVIDED, HOWEVER,  that  the  foregoing  shall  not  prevent  the  purchase  or
acquisition of Preferred Stock of such series to preserve the REIT status of the
Company  or pursuant to a  purchase or exchange offer made  on the same terms to
holders of all outstanding Preferred Stock of such series.
 
    If fewer than all of the outstanding shares of Preferred Stock of any series
are to be redeemed, the  number of shares to be  redeemed will be determined  by
the  Company and such shares may be redeemed pro rata from the holders of record
of such shares  in proportion to  the number of  such shares held  or for  which
redemption  is requested by such holder (with adjustments to avoid redemption of
fractional shares) or by lot in a manner determined by the Company.
 
    Notice of redemption will be  mailed at least 30 days  but not more than  60
days  before the redemption date to each  holder of record of Preferred Stock of
any series to be redeemed  at the address shown on  the share transfer books  of
the  Company. Each notice shall state: (i)  the redemption date; (ii) the number
of shares and series of the Preferred Stock to be redeemed; (iii) the redemption
price; (iv) the place or places where certificates for such Preferred Stock  are
to be surrendered for payment of the redemption price; (v) that dividends on the
shares to be redeemed will cease to accrue on such redemption date; and (vi) the
date  upon which the holder's conversion rights, if any, as to such shares shall
terminate. If fewer than all the shares of Preferred Stock of any series are  to
be  redeemed, the notice mailed  to each such holder  thereof shall also specify
the number of shares of Preferred Stock to be redeemed from each such holder. If
notice of redemption  of any Preferred  Stock has  been given and  if the  funds
necessary  for such redemption have  been set aside by  the Company in trust for
the benefit of the holders of any Preferred Stock so called for redemption, then
from and  after the  redemption date  dividends  will cease  to accrue  on  such
Preferred  Stock, and all rights  of the holders of  such shares will terminate,
except the right to receive the redemption price.
 
LIQUIDATION PREFERENCE
 
    Upon any voluntary or involuntary liquidation, dissolution or winding up  of
the  affairs of the Company,  then, before any distribution  or payment shall be
made to the holders of any Common Stock or any other class or series of  capital
shares  of the Company ranking junior to the Preferred Stock in the distribution
of assets upon any  liquidation, dissolution or winding  up of the Company,  the
holders  of each series of  Preferred Stock shall be  entitled to receive out of
assets of  the  Company  legally  available  for  distribution  to  shareholders
liquidating  distributions in the amount of the liquidation preference per share
(set forth in the applicable Prospectus Supplement), plus an amount equal to all
dividends accrued and unpaid thereon  (which shall not include any  accumulation
in  respect of  unpaid dividends  for prior  dividend periods  if such Preferred
Stock does not have a cumulative dividend). After payment of the full amount  of
the  liquidating  distributions  to  which they  are  entitled,  the  holders of
Preferred Stock will have no  right or claim to any  of the remaining assets  of
the  Company.  In  the  event  that,  upon  any  such  voluntary  or involuntary
liquidation, dissolution or winding up, the available assets of the Company  are
insufficient  to  pay  the  amount  of  the  liquidating  distributions  on  all
outstanding Preferred Stock and the corresponding amounts payable on all  shares
of  other classes or series of capital shares of the Company ranking on a parity
with the Preferred Stock in the distribution of assets, then the holders of  the
Preferred  Stock and all  other such classes  or series of  capital shares shall
share ratably  in any  such distribution  of assets  in proportion  to the  full
liquidating   distributions  to  which  they  would  otherwise  be  respectively
entitled.
 
                                       18

   
    If liquidating distributions shall have been made in full to all holders  of
Preferred  Stock, the remaining assets of the Company shall be distributed among
the holders of any other classes or  series of capital shares ranking junior  to
the  Preferred Stock upon  liquidation, dissolution or  winding up, according to
their respective rights  and preferences  and in  each case  according to  their
respective  number of shares. For such  purposes, the consolidation or merger of
the Company with or into  any other corporation, trust  or entity, or the  sale,
lease  or conveyance of all or substantially  all of the property or business of
the Company, shall  not be deemed  to constitute a  liquidation, dissolution  or
winding up of the Company.
    
 
VOTING RIGHTS
 
    Holders  of the Preferred Stock  will not have any  voting rights, except as
set forth  below or  as  otherwise from  time  to time  required  by law  or  as
indicated in the applicable Prospectus Supplement.
 
    Whenever  dividends on any shares of Preferred Stock shall be in arrears for
six or  more  consecutive quarterly  periods,  the  holders of  such  shares  of
Preferred Stock (voting separately as a class with all other series of preferred
stock  upon which  like voting rights  have been conferred  and are exercisable)
will be entitled to  vote for the  election of two  additional directors of  the
Company  at a special  meeting called by the  holders of record  of at least ten
percent (10%)  of any  series of  Preferred  stock so  in arrears  (unless  such
request  is received less than 90 days before the date fixed for the next annual
or special  meeting  of the  stockholders)  or at  the  next annual  meeting  of
stockholders,  and at each subsequent annual meeting until (i) if such series of
Preferred Stock has  a cumulative  dividend, all dividends  accumulated on  such
shares  of Preferred Stock  for the past  dividend periods and  the then current
dividend period shall have been fully paid or declared and a sum sufficient  for
the  payment thereof set aside  for payment or (ii)  if such series of Preferred
Stock does not have a cumulative dividend, four consecutive quarterly  dividends
shall  have been  fully paid or  declared and  a sum sufficient  for the payment
thereof set aside for payment.  In such case, the  entire board of directors  of
the Company will be increased by two directors.
 
    Unless  provided otherwise for any series of Preferred Stock, so long as any
shares of Preferred Stock remain outstanding, the Company will not, without  the
affirmative  vote or consent of the holders of at least two-thirds of the shares
of each series of Preferred Stock outstanding at the time, given in person or by
proxy, either in writing  or at a  meeting (such series  voting separately as  a
class), (i) authorize or create, or increase the authorized or issued amount of,
any  class or series of capital stock  ranking prior to such series of Preferred
Stock with respect to  payment of dividends or  the distribution of assets  upon
liquidation,  dissolution  or winding  up or  reclassify any  authorized capital
stock of  the  Company into  such  shares, or  create,  authorize or  issue  any
obligation  or security convertible into or evidencing the right to purchase any
such shares; or  (ii) amend,  alter or repeal  the provisions  of the  Company's
Articles  of  Incorporation  or the  Designating  Amendment for  such  series of
Preferred Stock, whether by merger, consolidation or otherwise (an "Event"),  so
as to materially and adversely affect any right, preference, privilege or voting
power  of  such series  of  Preferred Stock  or  the holders  thereof; PROVIDED,
HOWEVER, with respect to the occurrence of  any of the Events set forth in  (ii)
above, so long as the Preferred Stock remains outstanding with the terms thereof
materially  unchanged, taking into account that upon the occurrence of an Event,
the Company may not be  the surviving entity, the  occurrence of any such  Event
shall not be deemed to materially and adversely affect such rights, preferences,
privileges  or voting power  of holders of Preferred  Stock and provided further
that (x) any increase  in the amount  of the authorized  Preferred Stock or  the
creation or issuance of any other series of Preferred Stock, or (y) any increase
in  the  amount of  authorized  shares of  such series  or  any other  series of
Preferred Stock,  in  each case  ranking  on a  parity  with or  junior  to  the
Preferred  Stock of  such series  with respect  to payment  of dividends  or the
distribution of assets upon liquidation, dissolution or winding up, shall not be
deemed to materially and adversely  affect such rights, preferences,  privileges
or voting powers.
 
                                       19

    The  foregoing voting provisions will not apply  if, at or prior to the time
when the act with respect to which  such vote would otherwise be required  shall
be effected, all outstanding shares of such series of Preferred Stock shall have
been  redeemed or  called for  redemption and  sufficient funds  shall have been
deposited in trust to effect such redemption.
 
    Under Indiana law, notwithstanding anything to the contrary set forth above,
holders of each series of  Preferred Stock will be entitled  to vote as a  class
upon  any proposed  amendment to the  Articles of Incorporation,  whether or not
entitled to vote  thereon by  the Articles  of Incorporation,  if the  amendment
would (i) increase or decrease the aggregate number of authorized shares of such
series; (ii) effect an exchange or reclassification of all or part of the shares
of  the  series into  shares  of another  series;  (iii) effect  an  exchange or
reclassification, or create the right of exchange, of all or part of the  shares
of  another  class  or  series  into  shares  of  the  series;  (iv)  change the
designation, rights, preferences or limitations of  all or a part of the  shares
of  the  series; (v)  change the  shares of  all or  part of  the series  into a
different number of shares of the same  series; (vi) create a new series  having
rights  or preferences  with respect  to distributions  or dissolution  that are
prior, superior  or substantially  equal  to the  shares  of the  series;  (vii)
increase  the rights, preferences or number of authorized shares of any class or
series that, after giving  effect to the amendment,  have rights or  preferences
with  respect to  distributions or  to dissolution  that are  prior, superior or
substantially equal  to  the shares  of  the series;  (viii)  limit or  deny  an
existing  preemptive right of all  or part of the shares  of the series; or (ix)
cancel or  otherwise  affect rights  to  distributions or  dividends  that  have
accumulated  but have not yet been declared on  all or part of the shares of the
series.
 
CONVERSION RIGHTS
 
    The terms and conditions, if any,  upon which any series of Preferred  Stock
is  convertible into shares of Common Stock  will be set forth in the applicable
Prospectus Supplement relating thereto.  Such terms will  include the number  of
shares of Common Stock into which the shares of Preferred Stock are convertible,
the  conversion price (or manner of calculation thereof), the conversion period,
provisions as to whether conversion will be at the option of the holders of  the
Preferred  Stock  or the  Company,  the events  requiring  an adjustment  of the
conversion price  and  provisions  affecting  conversion in  the  event  of  the
redemption of such series of Preferred Stock.
 
SHAREHOLDER LIABILITY
 
    As   discussed  below  under  "Description  of  Common  Stock  --  General,"
applicable Indiana  law  provides  that no  shareholder,  including  holders  of
Preferred  Stock, shall be personally liable for the acts and obligations of the
Company and  that the  funds  and property  of the  Company  shall be  the  only
recourse for such acts or obligations.
 
RESTRICTIONS ON OWNERSHIP
 
    As  discussed below under "Description of Common Stock -- Certain Provisions
Affecting Change of Control,"  for the Company  to qualify as  a REIT under  the
Internal  Revenue Code of  1986, as amended  (the "Code"), not  more than 50% in
value of its outstanding capital shares may be owned, directly or indirectly, by
five or fewer individuals (as defined  in the Code to include certain  entities)
during  the last half of  a taxable year. To assist  the Company in meeting this
requirement, the  Company  may take  certain  actions to  limit  the  beneficial
ownership,  directly  or  indirectly,  by  a  single  person  of  the  Company's
outstanding equity securities,  including any  Preferred Stock  of the  Company.
Therefore,  the Designating  Amendment for  each series  of Preferred  Stock may
contain provisions  restricting  the ownership  and  transfer of  the  Preferred
Stock.   The  applicable  Prospectus  Supplement  will  specify  any  additional
ownership limitation relating to a series of Preferred Stock.
 
REGISTRAR AND TRANSFER AGENT
 
    The Registrar and Transfer Agent for  the Preferred Stock will be set  forth
in the applicable Prospectus Supplement.
 
                                       20

                        DESCRIPTION OF DEPOSITARY SHARES
 
GENERAL
 
    The  Company  may  issue  receipts  ("Depositary  Receipts")  for Depositary
Shares, each of  which will  represent a  fractional interest  of a  share of  a
particular  series of Preferred Stock, as specified in the applicable Prospectus
Supplement. Shares of Preferred Stock  of each series represented by  Depositary
Shares  will be deposited  under a separate deposit  agreement (each, a "Deposit
Agreement") among the Company, the depositary named therein (a "Preferred  Stock
Depositary")  and  the holders  from time  to time  of the  Depositary Receipts.
Subject to  the terms  of the  applicable  Deposit Agreement,  each owner  of  a
Depositary Receipt will be entitled, in proportion to the fractional interest of
a  share of a particular series of Preferred Stock represented by the Depositary
Shares evidenced by such Depositary Receipt,  to all the rights and  preferences
of  the  Preferred  Stock  represented  by  such  Depositary  Shares  (including
dividend, voting, conversion, redemption and liquidation rights).
 
    The Depositary  Shares  will  be evidenced  by  Depositary  Receipts  issued
pursuant to the applicable Deposit Agreement. Immediately following the issuance
and  delivery  of  the Preferred  Stock  by  the Company  to  a  Preferred Stock
Depositary, the Company will cause such Preferred Stock Depositary to issue,  on
behalf of the Company, the Depositary Receipts. Copies of the applicable form of
Deposit  Agreement and Depositary Receipt may  be obtained from the Company upon
request, and the statements  made hereunder relating  to Deposit Agreements  and
the  Depositary  Receipts  to  be issued  thereunder  are  summaries  of certain
anticipated provisions thereof and do not purport to be complete and are subject
to, and qualified in their  entirety by reference to,  all of the provisions  of
the applicable Deposit Agreement and related Depositary Receipts.
 
DIVIDENDS AND OTHER DISTRIBUTIONS
 
    A  Preferred  Stock  Depositary  will be  required  to  distribute  all cash
dividends or  other cash  distributions received  in respect  of the  applicable
Preferred  Stock to  the record  holders of  Depositary Receipts  evidencing the
related Depositary  Shares  in  proportion  to the  number  of  such  Depositary
Receipts  owned by  such holders, subject  to certain obligations  of holders to
file proofs, certificates and other information  and to pay certain charges  and
expenses to such Preferred Stock Depositary.
 
    In  the  event of  a  distribution other  than  in cash,  a  Preferred Stock
Depositary will be required to distribute property received by it to the  record
holders  of Depositary Receipts entitled thereto, subject to certain obligations
of holders to file proofs, certificates and other information and to pay certain
charges and expenses to such  Preferred Stock Depositary, unless such  Preferred
Stock  Depositary determines that it is  not feasible to make such distribution,
in which case  such Preferred  Stock Depositary may,  with the  approval of  the
Company,  sell such property and  distribute the net proceeds  from such sale to
such holders.
 
    No distribution  will be  made in  respect of  any Depositary  Share to  the
extent  that  it represents  any  Preferred Stock  which  has been  converted or
exchanged.
 
WITHDRAWAL OF STOCK
 
    Upon surrender of the Depositary Receipts  at the corporate trust office  of
the  applicable Preferred Stock Depositary (unless the related Depositary Shares
have previously been called  for redemption or  converted), the holders  thereof
will  be entitled  to delivery  at such  office, to  or upon  each such holder's
order, of the number of whole  or fractional shares of the applicable  Preferred
Stock  and  any money  or other  property represented  by the  Depositary Shares
evidenced by such Depositary  Receipts. Holders of  Depositary Receipts will  be
entitled to receive whole or fractional shares of the related Preferred Stock on
the  basis of the  proportion of Preferred Stock  represented by each Depositary
Share as specified in the applicable Prospectus Supplement, but holders of  such
shares  of Preferred Stock will not thereafter be entitled to receive Depositary
Shares therefor. If the Depositary Receipts  delivered by the holder evidence  a
number of
 
                                       21

Depositary  Shares in excess of the number of Depositary Shares representing the
number of shares of  Preferred Stock to be  withdrawn, the applicable  Preferred
Stock  Depositary will be required to deliver to  such holder at the same time a
new Depositary Receipt evidencing such excess number of Depositary Shares.
 
REDEMPTION OF DEPOSITARY SHARES
 
    Whenever the Company redeems shares of  Preferred Stock held by a  Preferred
Stock  Depositary, such Preferred Stock Depositary will be required to redeem as
of the same redemption date the number of Depositary Shares representing  shares
of the Preferred Stock so redeemed, provided the Company shall have paid in full
to  such Preferred Stock Depositary the  redemption price of the Preferred Stock
to be redeemed plus an amount equal to any accrued and unpaid dividends  thereon
to the date fixed for redemption. The redemption price per Depositary Share will
be  equal to the redemption  price and any other  amounts per share payable with
respect to the Preferred Stock. If fewer  than all the Depositary Shares are  to
be  redeemed, the Depositary Shares to be redeemed will be selected pro rata (as
nearly as may be practicable  without creating fractional Depositary Shares)  or
by  any other equitable method determined by the Company that preserves the REIT
status of the Company.
 
    From and after the  date fixed for redemption,  all dividends in respect  of
the shares of Preferred Stock so called for redemption will cease to accrue, the
Depositary  Shares  so called  for redemption  will  no longer  be deemed  to be
outstanding and all rights of the holders of the Depositary Receipts  evidencing
the  Depositary Shares so called for redemption  will cease, except the right to
receive any moneys payable upon such redemption and any money or other  property
to  which  the  holders of  such  Depositary  Receipts were  entitled  upon such
redemption upon surrender thereof to the applicable Preferred Stock Depositary.
 
VOTING OF THE PREFERRED STOCK
 
    Upon receipt of notice of any meeting at which the holders of the applicable
Preferred Stock  are entitled  to vote,  a Preferred  Stock Depositary  will  be
required  to mail  the information  contained in such  notice of  meeting to the
record holders of the Depositary Receipts evidencing the Depositary Shares which
represent such  Preferred  Stock.  Each record  holder  of  Depositary  Receipts
evidencing  Depositary Shares on the record date (which will be the same date as
the record  date for  the Preferred  Stock) will  be entitled  to instruct  such
Preferred Stock Depositary as to the exercise of the voting rights pertaining to
the  amount of Preferred  Stock represented by  such holder's Depositary Shares.
Such Preferred Stock Depositary will be required to vote the amount of Preferred
Stock  represented  by   such  Depositary   Shares  in   accordance  with   such
instructions, and the Company will agree to take all reasonable action which may
be  deemed necessary by such Preferred Stock  Depositary in order to enable such
Preferred Stock Depositary  to do so.  Such Preferred Stock  Depositary will  be
required  to abstain  from voting the  amount of Preferred  Stock represented by
such Depositary Shares to the extent  it does not receive specific  instructions
from  the holders  of Depositary Receipts  evidencing such  Depositary Shares. A
Preferred Stock Depositary will not be responsible for any failure to carry  out
any  instruction to vote, or for the manner  or effect of any such vote made, as
long as any such action or non-action is in good faith and does not result  from
negligence or willful misconduct of such Preferred Stock Depositary.
 
LIQUIDATION PREFERENCE
 
    In  the event of the liquidation, dissolution  or winding up of the Company,
whether voluntary or involuntary, the holders of each Depositary Receipt will be
entitled to the fraction  of the liquidation preference  accorded each share  of
Preferred Stock represented by the Depositary Share evidenced by such Depositary
Receipt, as set forth in the applicable Prospectus Supplement.
 
CONVERSION OF PREFERRED STOCK
 
    The Depositary Shares, as such, will not be convertible into Common Stock or
any  other securities or property of  the Company. Nevertheless, if so specified
in the applicable Prospectus  Supplement relating to  an offering of  Depositary
Shares,  the Depositary  Receipts may be  surrendered by holders  thereof to the
applicable  Preferred  Stock  Depositary  with  written  instructions  to   such
Preferred Stock Depositary to
 
                                       22

instruct  the Company to cause conversion  of the Preferred Stock represented by
the Depositary Shares evidenced by such Depositary Receipts into whole shares of
Common Stock, other shares of Preferred Stock of the Company or other shares  of
stock, and the Company will agree that upon receipt of such instructions and any
amounts  payable  in  respect  thereof, it  will  cause  the  conversion thereof
utilizing the same procedures as those provided for delivery of Preferred  Stock
to  effect such conversion.  If the Depositary Shares  evidenced by a Depositary
Receipt are to be converted in part  only, a new Depositary Receipt or  Receipts
will  be issued  for any  Depositary Shares not  to be  converted. No fractional
shares of Common Stock  will be issued upon  conversion, and if such  conversion
will  result in a fractional share being issued,  an amount will be paid in cash
by the Company  equal to the  value of  the fractional interest  based upon  the
closing  price  of  the Common  Stock  on the  last  business day  prior  to the
conversion.
 
AMENDMENT AND TERMINATION OF A DEPOSIT AGREEMENT
 
    Any form  of  Depositary Receipt  evidencing  Depositary Shares  which  will
represent  Preferred  Stock and  any provision  of a  Deposit Agreement  will be
permitted at any time  to be amended  by agreement between  the Company and  the
applicable  Preferred Stock  Depositary. However, any  amendment that materially
and adversely alters the  rights of the holders  of Depositary Receipts or  that
would  be materially and  adversely inconsistent with the  rights granted to the
holders of  the  related Preferred  Stock  will  not be  effective  unless  such
amendment  has been approved by  the existing holders of  at least two-thirds of
the applicable Depositary Shares evidenced by the applicable Depositary Receipts
then outstanding.  No  amendment shall  impair  the right,  subject  to  certain
anticipated  exceptions in the  Deposit Agreements, of  any holder of Depositary
Receipts to surrender any Depositary Receipt with instructions to deliver to the
holder the related  Preferred Stock and  all money and  other property, if  any,
represented  thereby, except  in order  to comply with  law. Every  holder of an
outstanding Depositary Receipt at the time any such amendment becomes  effective
shall  be deemed, by continuing to hold  such Depositary Receipt, to consent and
agree to such amendment and to be  bound by the applicable Deposit Agreement  as
amended thereby.
 
    A  Deposit Agreement will be permitted to  be terminated by the Company upon
not less than 30  days' prior written notice  to the applicable Preferred  Stock
Depositary if (i) such termination is necessary to preserve the Company's status
as  a REIT or (ii) a majority of each series of Preferred Stock affected by such
termination  consents  to  such  termination,  whereupon  such  Preferred  Stock
Depositary  will be  required to  deliver or  make available  to each  holder of
Depositary Receipts,  upon surrender  of the  Depositary Receipts  held by  such
holder,  such number  of whole  or fractional shares  of Preferred  Stock as are
represented by  the  Depositary Shares  evidenced  by such  Depositary  Receipts
together  with any other  property held by such  Preferred Stock Depositary with
respect to such Depositary  Receipts. The Company will  agree that if a  Deposit
Agreement  is terminated to  preserve the Company's  status as a  REIT, then the
Company will  use its  best efforts  to  list the  Preferred Stock  issued  upon
surrender of the related Depositary Shares on a national securities exchange. In
addition,   a  Deposit  Agreement  will   automatically  terminate  if  (i)  all
outstanding Depositary Shares  thereunder shall have  been redeemed, (ii)  there
shall  have been a final distribution in  respect of the related Preferred Stock
in connection with any liquidation, dissolution or winding up of the Company and
such distribution  shall have  been  distributed to  the holders  of  Depositary
Receipts  evidencing the Depositary Shares  representing such Preferred Stock or
(iii) each share of the related  Preferred Stock shall have been converted  into
stock of the Company not so represented by Depositary Shares.
 
CHARGES OF A PREFERRED STOCK DEPOSITARY
 
    The  Company will pay all transfer  and other taxes and governmental charges
arising solely  from the  existence of  a Deposit  Agreement. In  addition,  the
Company  will  pay the  fees and  expenses  of a  Preferred Stock  Depositary in
connection with  the  performance  of  its duties  under  a  Deposit  Agreement.
However,  holders of  Depositary Receipts  will pay the  fees and  expenses of a
Preferred Stock  Depositary for  any  duties requested  by  such holders  to  be
performed  which are outside  of those expressly provided  for in the applicable
Deposit Agreement.
 
                                       23

RESIGNATION AND REMOVAL OF DEPOSITARY
 
    A Preferred Stock  Depositary will  be permitted to  resign at  any time  by
delivering  to the Company notice of its election to do so, and the Company will
be permitted  at any  time to  remove  a Preferred  Stock Depositary,  any  such
resignation  or  removal to  take  effect upon  the  appointment of  a successor
Preferred Stock  Depositary.  A successor  Preferred  Stock Depositary  will  be
required  to  be  appointed within  60  days  after delivery  of  the  notice of
resignation or removal and will be required to be a bank or trust company having
its principal office  in the  United States and  having a  combined capital  and
surplus of at least $50,000,000.
 
MISCELLANEOUS
 
    A  Preferred  Stock Depositary  will be  required to  forward to  holders of
Depositary Receipts any reports  and communications from  the Company which  are
received  by  such  Preferred  Stock  Depositary  with  respect  to  the related
Preferred Stock.
 
    Neither a Preferred Stock Depositary nor the Company will be liable if it is
prevented from or delayed  in, by law or  any circumstances beyond its  control,
performing  its obligations  under a Deposit  Agreement. The  obligations of the
Company and  a Preferred  Stock Depositary  under a  Deposit Agreement  will  be
limited  to  performing  their  duties  thereunder  in  good  faith  and without
negligence (in the case  of any action  or inaction in  the voting of  Preferred
Stock  represented  by the  applicable Depositary  Shares), gross  negligence or
willful misconduct, and neither the  Company nor any applicable Preferred  Stock
Depositary  will be  obligated to  prosecute or  defend any  legal proceeding in
respect of any  Depositary Receipts.  Depositary Shares or  shares of  Preferred
Stock  represented  thereby  unless  satisfactory  indemnity  is  furnished. The
Company and any Preferred Stock Depositary will be permitted to rely on  written
advice  of counsel or accountants, or information provided by persons presenting
shares of Preferred Stock represented thereby for deposit, holders of Depositary
Receipts or other persons believed  in good faith to  be competent to give  such
information, and on documents believed in good faith to be genuine and signed by
a proper party.
 
    In  the event a Preferred Stock Depositary shall receive conflicting claims,
requests or instructions  from any holders  of Depositary Receipts,  on the  one
hand,  and the Company, on the other hand, such Preferred Stock Depositary shall
be entitled to act  on such claims, requests  or instructions received from  the
Company.
 
                          DESCRIPTION OF COMMON STOCK
 
GENERAL
 
    The  authorized capital stock of the  Company includes 150,000,000 shares of
Common Stock, $.01 par value per  share. Each outstanding share of Common  Stock
entitles  the holder to one vote on  all matters presented to shareholders for a
vote. Holders of  Common Stock  have no preemptive  rights. At  March 31,  1997,
there  were  31,442,291 shares  of  Common Stock  outstanding,  3,377,709 shares
reserved for issuance upon  exchange of outstanding  Units and 1,053,781  shares
reserved for issuance upon the exercise of outstanding stock options.
 
    Shares  of Common Stock currently outstanding  are listed for trading on the
New York Stock Exchange (the "NYSE"). The Company will apply to the NYSE to list
the additional shares  of Common  Stock to be  sold pursuant  to any  Prospectus
Supplement, and the Company anticipates that such shares will be so listed.
 
    The  Articles  of Incorporation  of  the Company  provide  for the  board of
directors to be divided into three  classes of directors, each class to  consist
as  nearly as possible of one-third of  the directors. At each annual meeting of
shareholders, the  class of  directors to  be elected  at such  meeting will  be
elected  for a three-year term  and the directors in  the other two classes will
continue in office.  The overall  effect of the  provisions in  the Articles  of
Incorporation  with  respect  to the  classified  board  may be  to  render more
difficult a change of control of the Company or removal of incumbent management.
Holders of Common Stock have no right  to cumulative voting for the election  of
directors.   Consequently,  at   each  annual   meeting  of   shareholders,  the
 
                                       24

holders of a plurality of  the shares of Common Stock  are able to elect all  of
the  successors of the  class of directors  whose term expires  at that meeting.
Directors may be removed only  for cause and only  with the affirmative vote  of
the  holders of a majority of the shares of Common Stock entitled to vote in the
election of directors.
 
    All shares of Common Stock issued  will be duly authorized, fully paid,  and
non-assessable.  Distributions may be paid to the holders of Common Stock if and
when declared by  the board of  directors of  the Company out  of funds  legally
available therefor. The Company intends to continue to pay quarterly dividends.
 
    Under  Indiana law, shareholders are generally  not liable for the Company's
debts or obligations. If the Company is liquidated, subject to the right of  any
holders  of preferred stock, if any, to receive preferential distributions, each
outstanding share of Common  Stock will be entitled  to participate pro rata  in
the  assets remaining  after payment  of, or  adequate provision  for, all known
debts and liabilities of the Company.
 
CERTAIN PROVISIONS AFFECTING CHANGE OF CONTROL
 
    GENERAL.  Pursuant to Indiana law, the Company cannot merge with or sell all
or substantially  all  of  the assets  of  the  Company, except  pursuant  to  a
resolution  approved by shareholders holding a  majority of the shares voting on
the resolution. The Company's Articles of Incorporation also contain  provisions
which  may  discourage  certain types  of  transactions involving  an  actual or
threatened change of control of the Company, including: (i) a requirement  that,
in  the case of certain mergers,  sales of assets, liquidations or dissolutions,
or reclassifications or recapitalizations involving  persons owning 10% or  more
of  the capital stock of the Company, such transactions be approved by a vote of
the holders of 80% of the issued and outstanding shares of capital stock of  the
Company  or three-fourths of the continuing directors, or provide for payment of
a price to affected shareholders for their shares not less than as specified  in
the  Articles  of  Incorporation;  (ii)  a  requirement  that  any  amendment or
alteration of  certain provisions  of the  Articles of  Incorporation  affecting
change  of  control  be  approved  by  the holders  of  80%  of  the  issued and
outstanding capital  stock  of the  Company;  and  (iii) a  staggered  board  of
directors  and a  limitation on  removal of  directors to  removal for  cause as
described above.
 
    The partnership  agreement  for  the  Operating  Partnership  also  contains
provisions which could discourage transactions involving an actual or threatened
change of control of the Company, including (i) a requirement that holders of at
least  90% of the outstanding  Units held by the  Company and other Unit holders
approve any voluntary sale, exchange  or other disposition, including merger  or
consolidation   (other  than  a  disposition   occurring  upon  a  financing  or
refinancing of the Operating  Partnership), of all or  substantially all of  the
assets  of the  Operating Partnership  in a  single transaction  or a  series of
related transactions; (ii) a restriction  against any assignment or transfer  by
the  Company  of  its  interest  in  the  Operating  Partnership;  and  (iii)  a
requirement that  holders of  more than  90% of  the Units  approve any  merger,
consolidation  or other combination of the  Company with or into another entity,
or  sale  of  all  or  substantially  all  of  the  Company's  assets,  or   any
reclassification  or recapitalization or change  of outstanding shares of Common
Stock (other than certain changes in par value, stock splits, stock dividends or
combinations) unless after the  transaction substantially all  of the assets  of
the  surviving entity are  contributed to the  Operating Partnership in exchange
for Units. On these matters, the Company's Units will be voted at the discretion
of the directors of the Company who are not officers or employees of the Company
and do not hold Units.
 
    OWNERSHIP LIMITS.  For the Company to  qualify as a REIT under the Code,  no
more  than 50% in value of its outstanding capital shares may be owned, directly
or indirectly, by five or fewer individuals  (as defined in the Code to  include
certain  entities)  during  the  last  half  of  a  taxable  year  or  during  a
proportionate part of  a shorter  taxable year. The  Common Stock  must also  be
beneficially  owned by 100 or more persons during at least 335 days of a taxable
year or  during a  proportionate part  of a  shorter taxable  year. Because  the
Company  expects to continue to qualify as a REIT, the Articles of Incorporation
of the Company contain restrictions on the acquisition of Common Stock  intended
to ensure compliance with these requirements.
 
                                       25

    The  Articles of Incorporation  contain a restriction  which authorizes, but
does not require, the board of directors to refuse to give effect to a  transfer
of  Common  Stock which,  in its  opinion,  might jeopardize  the status  of the
Company as  a REIT.  This provision  also renders  null and  void any  purported
acquisition  of shares which would result in the disqualification of the Company
as a REIT. The provision also gives the board of directors the authority to take
such actions as it deems advisable to enforce the provision. Such actions  might
include,  but are  not limited  to, refusing  to give  effect to,  or seeking to
enjoin, a transfer which  might jeopardize the Company's  status as a REIT.  The
provision  also requires any shareholder to provide the Company such information
regarding his direct and indirect ownership  of Common Stock as the Company  may
reasonably require.
 
REGISTRAR AND TRANSFER AGENT
 
    The  Registrar and  Transfer Agent  for the  Common Stock  is American Stock
Transfer & Trust Company, New York, New York.
 
                       FEDERAL INCOME TAX CONSIDERATIONS
 
    The following summary of material federal income tax considerations relevant
to the Company is based  on current law, is not  exhaustive of all possible  tax
considerations,  does not include  a detailed discussion of  any state, local or
foreign tax considerations  and does  not purport to  deal with  all aspects  of
taxation  that may be relevant to an investor  in light of his or her particular
circumstances or to certain types  of investors (including insurance  companies,
tax-exempt   entities,   financial  institutions   or   broker-dealers,  foreign
corporations and persons who are not citizens or residents of the United States)
who are subject to special treatment under the federal income tax laws. The  tax
treatment of an investor will also vary depending upon the terms of the specific
securities   acquired   by  such   investor.   Additional  federal   income  tax
considerations that are material  to investors in  securities other than  common
stock may be provided in the applicable Prospectus Supplement relating thereto.
 
    EACH  PROSPECTIVE PURCHASER IS ADVISED  TO CONSULT THE APPLICABLE PROSPECTUS
SUPPLEMENT AS WELL  AS HIS OR  HER OWN  TAX ADVISOR REGARDING  THE SPECIFIC  TAX
CONSEQUENCES  TO HIM OR HER OF THE PURCHASE, OWNERSHIP AND SALE OF SECURITIES IN
AN ENTITY ELECTING TO BE TAXED AS  A REIT, INCLUDING THE FEDERAL, STATE,  LOCAL,
FOREIGN  AND  OTHER  TAX  CONSEQUENCES OF  SUCH  PURCHASE,  OWNERSHIP,  SALE AND
ELECTION, AND OF POTENTIAL CHANGES IN APPLICABLE TAX LAWS.
 
TAXATION OF THE COMPANY
 
    GENERAL.  The Company expects to continue to be taxed as a REIT for  Federal
income  tax purposes. Management believes that the Company was organized and has
operated in such  a manner  as to meet  the requirements  for qualification  and
taxation  as a  REIT under the  Internal Revenue  Code of 1986,  as amended (the
"Code"), and that the Company intends to  continue to operate in such a  manner.
No  assurance, however, can be given that the Company has qualified as a REIT or
will continue to operate in a manner so as to remain qualified as a REIT.
 
    In the opinion of Bose  McKinney & Evans which has  acted as counsel to  the
Company  ("Counsel"), assuming the Company was  organized in conformity with and
has satisfied the requirements  for qualification and taxation  as a REIT  under
the  Code for each  of its taxable years  from and including  the first year for
which the Company made the election to  be taxed as a REIT, and the  assumptions
and  representations  referred  to  below  are  true,  the  proposed  methods of
operation of the  Company, the  Operating Partnership and  Duke Realty  Services
Limited  Partnership  (the "Services  Partnership") will  permit the  Company to
continue to qualify to be taxed as a REIT for its current and subsequent taxable
years.  This  opinion  is  based  upon  certain  assumptions  relating  to   the
organization  and  operation  of  Duke  Services,  Inc.  ("DSI"),  the Operating
Partnership and  the  Services  Partnership  and  is  conditioned  upon  certain
representations made
 
                                       26

by  Company personnel and  affiliates as to certain  factual matters relating to
the Company's past operations and the intended manner of future operation of the
Company, the Operating Partnership, and the Services Partnership. The opinion is
further based upon a letter  ruling received by the  Company from the IRS  dated
September  30,  1994,  which  concluded that  the  Company's  and  the Operating
Partnership's  distributive  shares  of  the   gross  income  of  the   Services
Partnership  will be in proportion to  their respective percentage shares of the
capital interests of the  partners of the Services  Partnership. Counsel is  not
aware   of  any  facts  or  circumstances  which  are  inconsistent  with  these
assumptions and representations. Unlike a tax  ruling, an opinion of counsel  is
not  binding upon the IRS, and  no assurance can be given  that the IRS will not
challenge the status of the Company as  a REIT for Federal income tax  purposes.
The  Company's qualification and taxation as a REIT has depended and will depend
upon, among other things, the Company's  ability to meet on a continuing  basis,
through  ownership  of  assets,  actual  annual  operating  results,  receipt of
qualifying real  estate  income,  distribution levels  and  diversity  of  stock
ownership,  the  various qualification  tests imposed  under the  Code discussed
below. Counsel will  not review  compliance with these  tests on  a periodic  or
continuing  basis.  Accordingly,  no  assurance  can  be  given  respecting  the
satisfaction of such tests. See "Taxation of the Company--Failure to Qualify."
 
    The following is  a general summary  of the Code  sections which govern  the
Federal  income tax treatment of a REIT  and its shareholders. These sections of
the Code are  highly technical  and complex. This  summary is  qualified in  its
entirety   by  the   applicable  Code  provisions,   Treasury  Regulations,  and
administrative and judicial interpretations thereof as currently in effect.
 
    So long as the Company qualifies for  taxation as a REIT and distributes  at
least  95% of its  REIT taxable income  (computed without regard  to net capital
gain or the dividends paid deduction) for its taxable year to its  shareholders,
it  will generally not be  subject to federal income  tax with respect to income
which it distributes to its shareholders. However, the Company may be subject to
federal income  tax  under certain  circumstances,  including taxes  at  regular
corporate  rates  on any  undistributed  REIT taxable  income,  the "alternative
minimum tax" on its  items of tax  preference, and taxes  imposed on income  and
gain generated by certain extraordinary transactions.
 
    REQUIREMENT  FOR QUALIFICATION.   The Code defines a  REIT as a corporation,
trust or association: (1) which is managed by one or more trustees or directors;
(2) the beneficial ownership of which is evidenced by transferable shares or  by
transferable  certificates of beneficial interest; (3) which would be taxable as
a domestic corporation but for Sections 856  through 859 of the Code; (4)  which
is  neither a financial institution nor  an insurance company subject to certain
provisions of the Code; (5) which has the calendar year as its taxable year; (6)
the beneficial ownership of which is held by 100 or more persons; (7) during the
last half of each  taxable year not  more than 50% in  value of the  outstanding
stock  of which is owned,  directly or indirectly, by  five or fewer individuals
(as defined  in the  Code to  include  certain entities);  and (8)  which  meets
certain  income  and  asset  tests, described  below.  The  Company  believes it
currently satisfies all requirements.
 
    DSI is  a "qualified  REIT subsidiary"  and  is not  treated as  a  separate
corporation.  Thus, in applying  the requirements described  herein, DSI will be
ignored for federal income tax purposes, and all of its assets, liabilities, and
items of income, deduction, and credit  will be treated as assets,  liabilities,
and  items of income, deduction, and credit of the Company. DSI, therefore, will
not be subject to federal corporate income taxation, although it may be  subject
to state and local taxation.
 
    INCOME  TESTS.  In order to qualify as  a REIT, there are three gross income
tests that must be satisfied annually. For purposes of these tests, the  Company
is  deemed to  be entitled to  a share of  the gross income  attributable to its
proportionate interest in any partnerships in which it holds an interest. First,
at least  75%  of  the  Company's gross  income  (excluding  gross  income  from
prohibited  transactions)  for each  taxable year  must  be derived  directly or
indirectly from investments  relating to  real property  (including "rents  from
real   property,"  gain  from  the  sale   of  real  property  and,  in  certain
circumstances, interest)  or  from  qualified types  of  temporary  investments.
Second,  at  least 95%  of the  Company's gross  income (excluding  gross income
 
                                       27

from prohibited transactions)  for each taxable  year must be  derived from  the
same  items which qualify under the 75% income tests or from dividends, interest
and gain  from the  sale or  disposition of  stock or  securities, or  from  any
combination of the foregoing. Third, less than 30% of the Company's gross income
(including  gross income from prohibited transactions) must be derived from gain
in connection with the sale or other disposition of stock or securities held for
less than one year, property in a prohibited transaction, and real property held
for less than  four years  (other than involuntary  conversions and  foreclosure
property).
 
    Rents  received by the Company will qualify as "rents from real property" in
satisfying the gross  income tests for  a REIT described  above only if  several
conditions (related to the relationship of the tenant to the Company, the method
of  determining the rent payable and nature of the property leased) are met. The
Company does not  anticipate receiving rents  in excess of  a de minimis  amount
that  fail to meet these  conditions. Finally, for rents  received to qualify as
"rents from real property," the Company generally must not operate or manage the
property or  furnish  or render  services  to  tenants, other  than  through  an
"independent  contractor"  that  is  adequately compensated  and  from  whom the
Company derives  no income;  provided,  however, that  the Company  may  perform
services  "usually or  customarily rendered"  in connection  with the  rental of
space for occupancy only and not otherwise considered "rendered to the occupant"
("Permissible Services").
 
    The Company provides certain management, development, construction and other
tenant-related services (collectively, "Real  Estate Services") with respect  to
the  Properties through the  Operating Partnership, which  is not an independent
contractor. Management  believes  that  the Real  Estate  Services  provided  to
tenants  by the  Operating Partnership are  Permissible Services.  To the extent
Real Estate Services  to tenants  do not constitute  Permissible Services,  such
services are performed by independent contractors.
 
    The Company derives a portion of its income from the Operating Partnership's
interest  as a limited partner in the  Services Partnership and its ownership of
DSI which  is  a general  partner  of  the Services  Partnership.  The  Services
Partnership  receives fees for  Real Estate Services  with respect to properties
that are not owned  by the Operating Partnership  and fees in consideration  for
the  performance  of  management  and administrative  services  with  respect to
Properties that are not  entirely owned by the  Operating Partnership. All or  a
portion of such fees will not qualify as "rents from real property" for purposes
of  the  75% or  95% gross  income  tests. Pursuant  to Treasury  Regulations, a
partner's  capital  interest  in  a  partnership  determines  its  proportionate
interest  in the partnership's gross income from partnership assets for purposes
of the 75% and 95% gross income tests. For this purpose, the capital interest of
a partner  is determined  by dividing  its capital  account by  the sum  of  all
partners'   capital  accounts.   The  partnership  agreement   of  the  Services
Partnership provides, however,  for varying allocations  of income which  differ
from  capital interests, subject to certain  limitations on the aggregate amount
of gross income which may be allocated to the Operating Partnership and DSI. The
Company has obtained a letter ruling from the IRS that allocations according  to
capital  interests are proper for  applying the 75% and  95% gross income tests.
Thus, for  purposes  of  these  gross income  tests,  the  Services  Partnership
allocates  its gross income to the Operating  Partnership and DSI based on their
capital interests  in the  Services Partnership.  Although certain  of the  fees
allocated  from the  Services Partnership  do not qualify  under the  75% or 95%
gross income tests as "rents from real property," the Company believes that  the
aggregate amount of such fees (and any other non-qualifying income) allocated to
the Company in any taxable year has not and will not cause the Company to exceed
the  limits on  non-qualifying income  under the 75%  or 95%  gross income tests
described above.
 
    If the Company fails to satisfy one or  both of the 75% or 95% gross  income
tests  for any taxable year, it may nevertheless qualify as a REIT for such year
if it is  entitled to relief  under certain provisions  of the Code.  It is  not
possible,  however, to state  whether in all circumstances  the Company would be
entitled to  the  benefit of  these  relief  provisions. Even  if  these  relief
provisions apply, a tax would be imposed on certain excess net income.
 
    ASSET  TESTS.  In order  for the Company to  maintain its qualification as a
REIT, at the close  of each quarter  of its taxable year,  it must also  satisfy
three  tests  relating  to  the  nature  of  its  assets.  First,  at  least 75%
 
                                       28

of the value of the Company's total  assets must be represented by "real  estate
assets,"  cash, cash items, and government securities. Second, not more than 25%
of the Company's total assets may be represented by securities other than  those
in  the 75%  assets class. Third,  of the  assets held in  securities other than
those in the 75% assets class, the value of any one issuer's securities owned by
the Company may not exceed  5% of the value of  the Company's total assets,  and
the  Company may not  own more than  10% of any  one issuer's outstanding voting
securities (excluding securities of  a qualified REIT  subsidiary as defined  in
the Code or another REIT).
 
    The  Company is deemed to directly hold  its proportionate share of all real
estate  and  other  assets  of  the   Operating  Partnership  as  well  as   its
proportionate  share of all assets deemed owned by the Operating Partnership and
DSI through their ownership of partnership interests in the Services Partnership
and other partnerships. As a result,  management believes that more than 75%  of
the  company's assets are  real estate assets. In  addition, management does not
expect the Company to hold (1) any securities representing more than 10% of  any
one  issuer's  voting  securities other  than  DSI,  which is  a  qualified REIT
subsidiary, nor (2) securities of  any one issuer exceeding  5% of the value  of
the  Company's gross  assets (determined  in accordance  with generally accepted
accounting principles).
 
    ANNUAL DISTRIBUTION REQUIREMENTS.   The Company,  in order to  qualify as  a
REIT, generally must distribute dividends (other than capital gain dividends) to
its  shareholders in an amount at  least equal to (A) the  sum of (i) 95% of the
Company's "REIT taxable income" (computed  without regard to the dividends  paid
deduction  and the Company's net  capital gain), and (ii)  95% of the net income
(after tax) if  any, from  foreclosure property, minus  (B) the  sum of  certain
items of non-cash income. To the extent that the Company does not distribute all
of  its net capital gain or distributes at least 95%, but less than 100%, of its
"REIT  taxable  income,"  as  adjusted,  it  will  be  subject  to  tax  on  the
undistributed  amount at regular capital gains and ordinary corporate tax rates.
Furthermore, if the Company should fail to distribute during each calendar  year
at  least the sum of (i) 85% of its REIT ordinary income for such year, (ii) 95%
of its REIT net capital gain income  for such year, and (iii) any  undistributed
taxable  income  from prior  periods,  the Company  will  be subject  to regular
capital gains and ordinary corporate tax rates on undistributed income and  also
may be subject to a 4% excise tax on undistributed income in certain events. The
Company  believes  that it  has  made and  intends  to continue  to  make timely
distributions sufficient  to satisfy  the annual  distribution requirements.  In
this  regard, the partnership agreement  of the Operating Partnership authorizes
the Company, as general partner, to take such steps as may be necessary to cause
the Operating Partnership to distribute to its partners an amount sufficient  to
permit  the Company  to meet  these distribution  requirements. It  is possible,
however, that the Company, from  time to time, may  not have sufficient cash  or
other  liquid assets to  meet the 95% distribution  requirement due primarily to
the  expenditure  of   cash  for  nondeductible   expenses  such  as   principal
amortization  or capital expenditures. In such  event, the Company may borrow or
may cause the Operating Partnership to arrange for short-term or other borrowing
to permit the  payment of required  dividends or  pay dividends in  the form  of
taxable  stock  dividends.  If  the  amount  of  nondeductible  expenses exceeds
non-cash deductions, the Operating Partnership may refinance its indebtedness to
reduce principal payments and borrow funds for capital expenditures.
 
    FAILURE TO QUALIFY.  If the Company fails to qualify for taxation as a  REIT
in  any  taxable  year,  the  Company will  be  subject  to  tax  (including any
applicable corporate alternative minimum tax)  on its taxable income at  regular
corporate  rates. Distributions to shareholders in any year in which the Company
fails to qualify  will not  be required to  be made  and, if made,  will not  be
deductible  by the Company.  Unless entitled to  relief under specific statutory
provisions, the Company also  will be disqualified from  taxation as a REIT  for
the  four taxable years following the  year during which qualification was lost.
It is not possible to  state whether in all  circumstances the Company would  be
entitled to such statutory relief.
 
TAX ASPECTS OF THE COMPANY'S INVESTMENTS IN PARTNERSHIPS
 
    EFFECT  OF TAX STATUS OF OPERATING  PARTNERSHIP AND SERVICES PARTNERSHIP AND
OTHER PARTNERSHIPS ON REIT QUALIFICATION.  All of the Company's investments  are
through DSI and the Operating Partnership, which in
 
                                       29

turn  hold interests in other  partnerships, including the Services Partnership.
The Company believes that the Operating Partnership, and each other  partnership
in  which it  holds an interest,  is properly  treated as a  partnership for tax
purposes (and not as an association taxable as a corporation). If, however,  the
Operating Partnership, the Services Partnership or any of the other partnerships
were treated as an association taxable as a corporation, the Company would cease
to qualify as a REIT.
 
    TAX  ALLOCATIONS WITH RESPECT TO THE  PROPERTIES.  The Operating Partnership
was formed by way of contributions of appreciated property (including certain of
the Properties) to the Operating Partnership. When property is contributed to  a
partnership  in exchange  for an  interest in  the partnership,  the partnership
generally takes a carryover basis in that property for tax purposes equal to the
adjusted basis of the contributing partner in the property, rather than a  basis
equal to the fair market value of the property at the time of contribution (this
difference  is referred to as  "Book-Tax Difference"). The partnership agreement
of the  Operating Partnership  requires allocations  of income,  gain, loss  and
deduction  with respect to a contributed Property be made in a manner consistent
with the  special  rules of  Section  704(c) of  the  Code and  the  regulations
thereunder,  which will tend to eliminate  the Book-Tax Differences with respect
to the  contributed  Properties over  the  life of  the  Operating  Partnership.
However,  because of certain technical limitations, the special allocation rules
of Section 704(c) may not always entirely eliminate the Book-Tax Differences  on
an  annual basis  or with respect  to a  specific taxable transaction  such as a
sale. Thus, the carryover  basis of the contributed  Properties in the hands  of
the  Operating Partnership  could cause  the Company  (i) to  be allocated lower
amounts of depreciation  and other  deductions for  tax purposes  than would  be
allocated  to the Company  if all Properties were  to have a  tax basis equal to
their fair market value  at the time  of contribution, and  (ii) possibly to  be
allocated  taxable gain in the event of a sale of such contributed Properties in
excess of the economic or  book income allocated to the  Company as a result  of
such  sale. The foregoing principles also  apply in determining the earnings and
profits of the Company for purposes of determining the portion of  distributions
taxable  as dividend income. The application of these rules over time may result
in a higher portion  of distributions being taxed  as dividends than would  have
occurred  had the  Company purchased  its interests  in the  Properties at their
agreed values.
 
TAXATION OF TAXABLE DOMESTIC SHAREHOLDERS
 
    As long  as the  Company qualifies  as  a REIT,  distributions made  to  the
Company's  taxable domestic shareholders out  of current or accumulated earnings
and profits (and not  designated as capital gain  dividends) will be taken  into
account  by them as ordinary  income and will not  be eligible for the dividends
received deduction  for  corporations.  Distributions  that  are  designated  as
capital  gain dividends will be taxed as  long-term capital gains (to the extent
they do not exceed the Company's actual net capital gain for the taxable  year).
However, corporate holders may be required to treat up to 20% of certain capital
gain  dividends  as  ordinary income.  Distributions  in excess  of  current and
accumulated earnings and profits will not be  taxable to a holder to the  extent
that  they do  not exceed  the adjusted  tax basis  of the  holder's shares, but
rather will reduce the adjusted  basis of such shares.  To the extent that  such
distributions  exceed  the adjusted  basis  of a  holder's  shares they  will be
included in income as long-term capital gain (or short-term capital gain if  the
shares  have been held for  one year or less) assuming  the shares are a capital
asset in the  hands of the  holder. In  addition, any dividend  declared by  the
Company in October, November or December of any year payable to a shareholder of
record  on a specified date in  any such month shall be  treated as both paid by
the Company  and  received by  the  shareholder on  December  31 of  such  year;
provided that the dividend is actually paid by the Company during January of the
following calendar year. Shareholders may not include in their individual income
tax returns any net operating losses or capital losses of the Company.
 
    In  general, a domestic shareholder will realize capital gain or loss on the
disposition of common stock  equal to the difference  between (i) the amount  of
cash  and the fair market value of any property received on such disposition and
(ii) the shareholder's adjusted  basis of such common  stock. Such gain or  loss
generally  will constitute long-term capital gain or loss if the shareholder has
held such shares for more than one year. Loss upon a sale or exchange of  common
stock   by   a   shareholder  who   has   held   such  common   stock   for  six
 
                                       30

months or less (after applying certain holding period rules) will be treated  as
a  long-term  capital  loss to  the  extent  of distributions  from  the Company
required to be treated by such shareholder as long-term capital gain.
 
TAXATION OF TAX-EXEMPT SHAREHOLDERS
 
    Tax-exempt entities, including qualified employee pension and profit sharing
trusts and individual  retirement accounts  ("Exempt Organizations"),  generally
are  exempt from federal income taxation.  However, they are subject to taxation
on their unrelated business taxable  income ('UBTI"). While many investments  in
real  estate generate UBTI, the IRS has  issued a published ruling that dividend
distributions from a REIT to an exempt employee pension trust do not  constitute
UBTI,  provided  that  the shares  of  the REIT  are  not otherwise  used  in an
unrelated trade or business of the exempt employee pension trust. Based on  that
ruling,  amounts distributed  by the  Company to  Exempt Organizations generally
should not  constitute UBTI.  However, if  an Exempt  Organization finances  its
acquisitions  of the common shares  with debt, a portion  of its income from the
Company will constitute  UBTI pursuant  to the  "debt-financed property"  rules.
Furthermore, social clubs, voluntary employee benefit associations, supplemental
unemployment  benefit trusts, and qualified group  legal services plans that are
exempt from taxation under paragraphs (7), (9), (17), and (20), respectively, of
Code section 501(c) are  subject to different UBTI  rules, which generally  will
require them to characterize distributions from the Company as UBTI.
 
    In  addition, in certain circumstances, a  pension trust that owns more than
10% of the Company's shares is required  to treat a percentage of the  dividends
from  the Company as  UBTI (the "UBTI  Percentage"). The UBTI  Percentage is the
gross income  derived  by  the  Company from  an  unrelated  trade  or  business
(determined  as if the Company were a pension trust) divided by the gross income
of the Company  for the  year in  which the dividends  are paid.  The UBTI  rule
applies  to a pension trust holding more than 10% of the Company's stock only if
(i) the UBTI Percentage is at least 5%, (ii) the Company qualifies as a REIT  by
reason  of the modification  of the "five or  fewer" stock ownership requirement
that allows the  beneficiaries of  the pension trust  to be  treated as  holding
shares  of the Company in proportion to their actuarial interests in the pension
trust, and (iii) either (A) one pension trust owns more that 25% of the value of
the Company's shares or (B) a group of pension trusts individually holding  more
than 10% of the value of the Company's shares collectively owns more than 50% of
the value of the Company's shares.
 
BACKUP WITHHOLDING
 
    The  Company will report to its domestic shareholders and the IRS the amount
of dividends paid during each calendar year, and the amount of tax withheld,  if
any.  Under the backup withholding rules, a shareholder may be subject to backup
withholding at the rate of 31% with respect to dividends paid unless such holder
(a) is a corporation or comes  within certain other exempt categories and,  when
required,  demonstrates  this fact,  or (b)  provides a  taxpayer identification
number, certifies  as to  no  loss of  exemption  from backup  withholding,  and
otherwise complies with applicable requirements of the backup withholding rules.
A  shareholder  that does  not  provide the  Company  with his  correct taxpayer
identification number may also be subject  to penalties imposed by the IRS.  Any
amount  paid as backup withholding will  be creditable against the shareholder's
income tax liability.  In addition, the  Company may be  required to withhold  a
portion  of capital gain  distributions to any shareholders  who fail to certify
their non-foreign status to the Company.
 
    The Treasury Department recently  issued proposed regulations regarding  the
withholding  and information  reporting rules  discussed above.  In general, the
proposed regulations do not alter  the substantive withholding requirements  but
unify  current  certification  procedures  and  forms,  and  clarify  and modify
reliance standards. If finalized in their current form, the proposed regulations
would generally be effective for payments made after December 31, 1997,  subject
to certain transition rules.
 
TAXATION OF NON-U.S. SHAREHOLDERS
 
    The  rules  governing  U.S.  Federal income  taxation  of  nonresident alien
individuals,  foreign  corporations,  foreign  partnerships  and  other  foreign
shareholders (collectively, "Non-U.S. Shareholders") are
 
                                       31

complex,  and no  attempt will  be made  herein to  provide more  than a limited
summary of such  rules. Prospective  Non-U.S. Shareholders  should consult  with
their  own tax advisors to determine the impact of U.S. Federal, state and local
income tax laws  with regard  to an investment  in common  stock, including  any
reporting requirements.
 
    Distributions  that are not attributable to  gain from sales or exchanges by
the Company of U.S. real property interests and not designated by the Company as
capital gain dividends will  be treated as dividends  of ordinary income to  the
extent  that they are made out of current or accumulated earnings and profits of
the Company. Such distributions,  ordinarily, will be  subject to a  withholding
tax  equal to 30% of  the gross amount of  the distribution unless an applicable
tax treaty reduces that tax. Distributions in excess of current and  accumulated
earnings  and  profits  of  the  Company  will  not  be  taxable  to  a Non-U.S.
Shareholder to the  extent that they  do not  exceed the adjusted  basis of  the
shareholder's  common stock, but  rather will reduce the  adjusted basis of such
common stock. To  the extent  that such  distributions exceed  the adjusted  tax
basis  of a  Non-U.S. Shareholder's  common stock,  they will  give rise  to tax
liability if the Non-U.S. Shareholder would  otherwise be subject to tax on  any
gain  from the sale  or disposition of  his common stock  as described below (in
which case  they  also may  be  subject  to a  30%  branch profits  tax  if  the
shareholder  is a foreign corporation). As a result of a legislative change made
by the Small Business  Job Protection Act of  1996, effective for  distributions
made  after August  20, 1996,  the Company  is required  to withhold  10% of any
distribution in  excess  of  the  Company's  current  accumulated  earnings  and
profits. Consequently, although the Company intends to withhold at a rate of 30%
on  the entire amount of  any distribution, to the  extent that the Company does
not do so any portion of a distribution not subject to withholding at a rate  of
30%  will be  subject to  withholding at  a rate  of 10%.  However, the Non-U.S.
Shareholder may seek a refund of such amounts from the IRS if it is subsequently
determined that  such  distribution  was,  in fact,  in  excess  of  current  or
accumulated earnings and profits of the Company, and the amount withheld exceeds
the  Non-U.S. Shareholder's United States tax liability, if any, with respect to
the distribution.
 
    For any year in  which the Company qualifies  as a REIT, distributions  that
are  attributable to gain  from sales or  exchanges by the  Company of U.S. real
property interests will be taxed to a Non-U.S. Shareholder under the  provisions
of  the Foreign Investment  in Real Property  Tax Act of  1980 ("FIRPTA") at the
normal capital  gain  rates  applicable to  domestic  shareholders  (subject  to
applicable  alternative minimum tax and a special alternative minimum tax in the
case of nonresident  alien individuals). Also,  distributions subject to  FIRPTA
may  be subject to a 30% branch profits tax in the hands of a corporate Non-U.S.
Shareholder not entitled to treaty relief or exemption. The Company is  required
to  withhold  35% of  any distribution  that is  or could  be designated  by the
Company as a capital  gain dividend. The amount  withheld is creditable  against
the Non-U.S. Shareholder's FIRPTA tax liability.
 
    Gain  recognized  by a  Non-U.S.  Shareholder upon  a  sale of  common stock
generally will  not be  taxed under  FIRPTA if  the Company  is a  "domestically
controlled  REIT," defined generally  as a REIT  in which at  all times during a
specified testing period less than 50% in  value of the stock was held  directly
or   indirectly  by  foreign  persons.  The   Company  believes  that  it  is  a
"domestically controlled REIT," and,  therefore, that the  sale of common  stock
will  not be subject to taxation under FIRPTA. If the gain on the sale of common
stock were to be subject to tax under FIRPTA, the Non-U.S. Shareholder would  be
subject to the same treatment as domestic shareholders with respect to such gain
(subject to applicable alternative minimum tax and a special alternative minimum
tax  in the  case of  nonresident alien individuals),  and the  purchaser of the
common stock would  be required  to withhold  and remit to  the IRS  10% of  the
purchase price.
 
STATE AND LOCAL TAXES
 
    The  Company or its shareholders  or both may be  subject to state, local or
other taxation in various state,  local or other jurisdictions, including  those
in   which  they  transact  business  or  reside.  The  tax  treatment  in  such
jurisdictions may  differ from  the Federal  income tax  consequences  discussed
above.  Consequently,  prospective  shareholders should  consult  their  own tax
advisors regarding the effect of  state and local tax  laws on an investment  in
shares of the Company.
 
                                       32

                              PLAN OF DISTRIBUTION
 
    The  Company and the Operating Partnership may sell Securities to or through
underwriters, and  also may  sell  Securities directly  to other  purchasers  or
through agents.
 
    The  distribution of the Securities may be effected from time to time in one
or more transactions at  a fixed price  or prices, which may  be changed, or  at
market  prices  prevailing  at the  time  of  sale, at  prices  related  to such
prevailing market prices or at negotiated prices.
 
    In  connection  with  the  sale  of  Securities,  underwriters  may  receive
compensation from the Company, from the Operating Partnership or from purchasers
of  Securities,  for whom  they may  act as  agents, in  the form  of discounts,
concessions, or  commissions. Underwriters  may sell  Securities to  or  through
dealers,  and such  dealers may receive  compensation in the  form of discounts,
concessions, or commissions  from the underwriters  and/or commissions from  the
purchasers  for whom they  may act as agents.  Underwriters, dealers, and agents
that participate  in  the  distribution  of  Securities  may  be  deemed  to  be
underwriters,  and any discounts or commissions they receive from the Company or
the Operating  Partnership, and  any profit  on the  resale of  Securities  they
realize  may be deemed  to be underwriting discounts  and commissions, under the
Securities Act. Any such underwriter or  agent will be identified, and any  such
compensation  received from  the Company  or the  Operating Partnership  will be
described, in the Prospectus Supplement.
 
    Unless otherwise specified in the related Prospectus Supplement, each series
of Securities will be a new issue with no established trading market, other than
the Common Stock which is  listed on the NYSE. Any  shares of Common Stock  sold
pursuant  to a Prospectus Supplement will be listed on such exchange, subject to
official notice of issuance. The Company or the Operating Partnership may  elect
to  list any series of Debt Securities,  Preferred Stock or Depositary Shares on
an exchange, but neither is obligated to do so. It is possible that one or  more
underwriters  may  make a  market in  a series  of Securities,  but will  not be
obligated to do so  and may discontinue  any market making  at any time  without
notice.  Therefore, no assurance can be given as to the liquidity of the trading
market for the Securities.
 
    Under agreements the Company and  the Operating Partnership may enter  into,
underwriters,  dealers,  and  agents  who  participate  in  the  distribution of
Securities may be entitled  to indemnification by the  Company or the  Operating
Partnership   against  certain  liabilities,  including  liabilities  under  the
Securities Act.
 
    Underwriters, dealers and agents may engage in transactions with, or perform
services for, or be  customers of, the Company  or the Operating Partnership  in
the ordinary course of business.
 
    If  so indicated in the applicable Prospectus Supplement, the Company or the
Operating Partnership, as the case may be, will authorize underwriters or  other
persons acting as the Company's or the Operating Partnership's agents to solicit
offers  by certain institutions  to purchase Securities from  the Company or the
Operating Partnership pursuant to contracts  providing for payment and  delivery
on  a future date.  Institutions with which  such contracts may  be made include
commercial and  savings banks,  insurance companies,  pension funds,  investment
companies,  educational and charitable institutions and others, but in all cases
such institutions must be approved by the Company or the Operating  Partnership,
as  the case may  be. The obligations  of any purchaser  under any such contract
will be subject to the condition that  the purchase of the Securities shall  not
at  the time  of delivery be  prohibited under  the laws of  the jurisdiction to
which such purchaser is subject. The underwriters and such other agents will not
have any  responsibility in  respect  of the  validity  or performance  of  such
contracts.

                                 LEGAL OPINIONS
 
    The  legality of the Securities offered hereby  is being passed upon for the
Company by  Bose  McKinney &  Evans,  Indianapolis, Indiana.  In  addition,  the
description  of Federal income tax matters contained in this Prospectus entitled
"Federal Income Tax Considerations" is based upon the opinion of Bose McKinney &
Evans. John W.  Wynne and Darell  E. Zink,  Jr., officers and  directors of  the
Company,  were  partners  in  Bose  McKinney  &  Evans  through  1987  and 1982,
respectively, and were of counsel to that firm until December, 1990.
 
                                    EXPERTS
 
    The Consolidated Financial Statements and  related Schedules of the  Company
and  of the Operating Partnership as of December 31, 1996 and 1995, and for each
of the years in the three-year period ended December 31, 1996, each incorporated
herein by reference have been incorporated  herein in reliance upon the  reports
of  KPMG  Peat  Marwick  LLP,  independent  certified  public  accountants, also
incorporated by reference herein, and upon the authority of said firm as experts
in accounting and auditing.
 
   
    With respect to the unaudited interim financial information for the  periods
ended March 31, 1997 and 1996, incorporated by reference herein, the independent
certified  public accountants have reported that they applied limited procedures
in accordance  with professional  standards for  a review  of such  information.
However,  their separate  reports included  in the  Company's and  the Operating
Partnership's quarterly reports  on Form 10-Q  for the quarter  ended March  31,
1997,  and incorporated by reference  herein, state that they  did not audit and
they  do  not  express  an  opinion  on  that  interim  financial   information.
Accordingly,  the degree of reliance on their reports on such information should
be restricted in light of the  limited nature of the review procedures  applied.
The accountants are not subject to the liability provisions of section 11 of the
Securities  Act of  1933 for  their reports  on the  unaudited interim financial
information because  those  reports  are not  a  "report"  or a  "part"  of  the
registration  statement  prepared or  certified  by the  accountants  within the
meaning of sections 7 and 11 of such Act.

ITEM 15.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.
 
    The  Company is an Indiana corporation. The Company's officers and directors
are and will be indemnified under Indiana law, the Articles of Incorporation  of
the  Company, and  the partnership agreements  of the  Operating Partnership and
Duke Realty Services Limited Partnership against certain liabilities. Chapter 37
of The Indiana  Business Corporation  Law (the "IBCL")  requires a  corporation,
unless  its articles of incorporation provide otherwise, to indemnify a director
or an officer  of the corporation  who is  wholly successful, on  the merits  or
otherwise,  in the defense of any  threatened, pending or completed action, suit
or proceeding,  whether civil,  criminal,  administrative or  investigative  and
whether formal or informal, against reasonable expenses, including counsel fees,
incurred   in  connection  with  the   proceeding.  The  Company's  Articles  of
Incorporation do not contain any provision prohibiting such indemnification.
 
    The IBCL  also  permits a  corporation  to indemnify  a  director,  officer,
employee  or agent who is made a party  to a proceeding because the person was a
director, officer,  employee  or  agent of  the  corporation  against  liability
incurred in the proceeding if (i) the individual's conduct was in good faith and
(ii)  the  individual reasonably  believed (A)  in  the case  of conduct  in the
individual's official capacity with the corporation that the conduct was in  the
corporation's  best interests and  (B) in all other  cases that the individual's
conduct was at least not opposed  to the corporation's best interests and  (iii)
in  the case of a criminal proceeding,  the individual either (A) had reasonable
cause to believe the  individual's conduct was lawful  or (B) had no  reasonable
cause  to believe the individual's conduct was unlawful. The IBCL also permits a
corporation to  pay for  or reimburse  reasonable expenses  incurred before  the
final   disposition  of  the  proceeding  and   permits  a  court  of  competent
jurisdiction to order a  corporation to indemnify a  director or officer if  the
court   determines  that  the  person  is  fairly  and  reasonably  entitled  to
indemnification in view or  all the relevant circumstances,  whether or not  the
person met the standards for indemnification otherwise provided in the IBCL.
 
    The  Company's  Articles  of Incorporation  provide  for  certain additional
limitations of liability and indemnification.  Section 13.01 of the Articles  of
Incorporation  provides that  a director shall  not be personally  liable to the
Company or its shareholders for monetary damages for breach of fiduciary duty as
a director, except for liability  (i) for any breach  of the director's duty  of
loyalty  to the Company or  its shareholders, (ii) for  acts or omissions not in
good faith or  which involve intentional  misconduct or a  knowing violation  of
law,  (iii) for voting for or assenting to an unlawful distribution, or (iv) for
any transaction from which  the director derived  an improper personal  benefit.
Section  13.02  of the  Articles of  Incorporation  generally provides  that any
director or officer of the Company or  any person who is serving at the  request
of the Company as a director, officer, employee or agent of another entity shall
be indemnified and held harmless by the Company to the fullest extent authorized
by the IBCL against all expense, liability
 
                                      II-1

and  loss (including attorneys' fees, judgments, fines certain employee benefits
excise taxes  or  penalties  and amounts  paid  or  to be  paid  in  settlement)
reasonably   incurred  or  suffered  in   connection  with  a  civil,  criminal,
administrative or investigative action, suit or proceeding to which such  person
is  a party  by reason of  the person's  service with or  at the  request of the
Company. Section  13.02 of  the  Articles of  Incorporation also  provides  such
persons  with certain rights to be paid  by the Company the expenses incurred in
defending any such proceeding in advance of the final disposition and the  right
to  enforce indemnification claims against the  Company by bringing suit against
the Company.
 
    The Company's Articles  of Incorporation authorize  the Company to  maintain
insurance  to protect itself and any director, officer, employee or agent of the
Company or  another  corporation, partnership,  joint  venture, trust  or  other
enterprise  against expense, liability or loss, whether or not the Company would
have the power to indemnify such person against such expense, liability or  loss
under the IBCL.
 
    Each  of the partnership  agreements for the  Operating Partnership and Duke
Realty Services Limited  Partnership also  provides for  indemnification of  the
Company and its officers and directors to substantially the same extent provided
to  officers and directors of the Company  in its Articles of Incorporation, and
limits the  liability of  the Company  and  its officers  and directors  to  the
Operating  Partnership  and its  partners and  to  Duke Realty  Services Limited
Partnership and its  partners, respectively,  to substantially  the same  extent
limited under the Company's Articles of Incorporation.

ITEM 17.  UNDERTAKINGS.
 
    Each  of  the  undersigned  Registrants hereby  undertakes  that  insofar as
indemnification for liabilities arising under the Securities Act of 1933 may  be
permitted  to  directors, officers  and  controlling persons  of  the registrant
pursuant to  the provisions  described  in Item  15  above, or  otherwise,  such
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 Registrants of expenses
incurred or paid by a director, officer or controlling person of the Registrants
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,  each  Registrant will,  unless in  the opinion  of its  counsel the
matter has  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.
 
    The undersigned Registrants hereby further undertake:
 
        (1)  To file, during any period in which offers or sales are being made,
    a post-effective amendment to this Registration Statement:
 
           (i) To include  any prospectus  required by section  10(a)(3) of  the
       Securities Act of 1933;
 
           (ii)  To reflect in the prospectus  any facts or events arising after
       the effective  date of  the Registration  Statement (or  the most  recent
       post-effective   amendment  thereof)   which,  individually   or  in  the
       aggregate, represent a fundamental change in the information set forth in
       the Registration Statement; notwithstanding  the foregoing, any  increase
       or decrease in volume of securities offered (if the total dollar value of
       securities  offered would not  exceed that which  was registered) and any
       deviation from the  low or  high end  of the  estimated maximum  offering
       range  may  be  reflected  in  the  form  of  prospectus  filed  with the
       Commission pursuant to Rule 424(b) (Section 230.424(b) of 17 C.F.R.)  if,
       in  the aggregate, the changes in volume and price represent no more than
       a 20% change  in the maximum  aggregate offering price  set forth in  the
       "Calculation  of Registration  Fee" table  in the  effective registration
       statement; and
 
          (iii) To include any material information with respect to the plan  of
       distribution  not previously  disclosed in the  registration statement or
       any material change to such information in the registration statement;
 
    PROVIDED, HOWEVER, that paragraphs  (1)(i) and (1)(ii) do  not apply if  the
    Registration  Statement  is on  Form S-3  or Form  S-8, and  the information
    required   to    be   included    in   a    post-effective   amendment    by
 
                                      II-3

    those  paragraphs is contained in periodic  reports filed by the Registrants
    pursuant to section 13  or section 15(d) of  the Securities Exchange Act  of
    1934 that are incorporated by reference in the Registration Statement.
 
        (2)  That,  for  the  purpose of  determining  any  liability  under the
    Securities Act of 1933, each  such post-effective amendment 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.
 
        (3) To remove from registration  by means of a post-effective  amendment
    any   of  the  securities  being  registered  which  remain  unsold  at  the
    termination of the offering.
 
        The undersigned Registrants hereby further undertake that, for  purposes
    of  determining any liability under the  Securities Act of 1933, each filing
    of the  Registrants' annual  reports pursuant  to section  13(a) or  section
    15(d)  of the Securities  Exchange Act of 1934  (and, where applicable, each
    filing of an employee benefit plan's annual report pursuant to section 15(d)
    of the Securities Exchange Act of 1934) that is incorporated by reference in
    the Registration  Statement  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.
 
    The undersigned Registrants further undertake that:
 
        (a)  For purposes of determining any  liability under the Securities Act
    of 1933, as amended  (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 the  form of prospectus filed by the  Registrants
    pursuant to Rule 424(b)(l) or (4) or 497(h) under the Act shall be deemed to
    be  part  of the  Registration  Statement as  of  the time  it  was declared
    effective.
 
        (b) 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.
 
                                      II-4

                                   SIGNATURES
 
   
    Pursuant  to the requirements of the Securities Act of 1933, each Registrant
certifies that it has  reasonable grounds to  believe that it  meets all of  the
requirements  for filing on  Form S-3 and  has duly caused  this Amendment to be
signed on its behalf by the undersigned, thereunto duly authorized, in the  City
of Indianapolis, State of Indiana, on May 20, 1997.
