          WHEREAS, the Issuer executed and delivered its Indenture (the
"Original Indenture"), dated as of September 19, 1995, to the Trustee to issue
from time to time for its lawful purposes debt securities evidencing its
unsecured and unsubordinated indebtedness.

          WHEREAS, the Original Indenture provides that by means of a
supplemental indenture, the Issuer may create one or more series of its debt
securities and establish the form and terms and conditions thereof.

          WHEREAS, the Issuer intends by this Supplemental Indenture to (i)
create a series of debt securities, in an aggregate principal amount not to
exceed $100,000,000, entitled "Duke Realty Limited Partnership 6 3/4% Notes due
2008" (the "Notes"); and (ii) establish the form and the terms and conditions of
such Notes.

          WHEREAS, the Board of Directors of Duke Realty Investments, Inc., the
general partner of the Issuer, acting through authority delegated to its Finance
Committee, has approved the creation of the Notes and the form, terms and
conditions thereof.

          WHEREAS, the consent of Holders to the execution and delivery of this
Supplemental Indenture is not required, and all other actions required to be
taken under the Original Indenture with respect to this Supplemental Indenture
have been taken.

          NOW, THEREFORE IT IS AGREED:


                                     ARTICLE ONE
     DEFINITIONS, CREATION, FORM AND TERMS AND CONDITIONS OF THE DEBT SECURITIES

     SECTION 1.01   DEFINITIONS.  Capitalized terms used in this Supplemental
Indenture and not otherwise defined shall have the meanings ascribed to them in
the Original Indenture.  In addition, the following terms shall have the
following meanings to be equally applicable to both the singular and the plural
forms of the terms defined:

          "DTC" means The Depository Trust Company.

          "GLOBAL NOTE" means a single fully-registered global note in 
book-entry form, without coupons, substantially in the form of Exhibit A 
attached hereto.


                                       2




          "INDENTURE" means the Original Indenture as supplemented by this Fifth
Supplemental Indenture.

          "MAKE-WHOLE AMOUNT" means, in connection with any optional 
redemption or accelerated payment of any Note, the excess, if any, of (i) the 
aggregate present value as of the date of such redemption or accelerated 
payment of each dollar of principal being redeemed or paid and the amount of 
interest (exclusive of interest accrued to the date of redemption or 
accelerated payment) that would have been payable in respect of each such 
dollar if such redemption or accelerated payment had not been made, 
determined by discounting, on a semi-annual basis, such principal and 
interest at the Reinvestment Rate (determined on the third Business Day 
preceding the date such notice of redemption is given or declaration of 
acceleration is made) from the respective dates on which such principal and 
interest would have been payable if such redemption or accelerated payment 
had not been made, over (ii) the aggregate principal amount of the Notes 
being redeemed or paid.

          "NOTES" means the Issuer's 6 3/4% Notes due May 30, 2008, a form of
which is attached hereto as Exhibit A.

          "REDEMPTION PRICE" means the sum of (i) the principal amount of the
Notes being redeemed plus accrued interest thereon to the Redemption Date and
(ii) the Make-Whole Amount, if any, with respect to such Notes.

          "REINVESTMENT RATE" means .25% plus the arithmetic mean of the yields
under the respective heading "Week Ending" published in the most recent
Statistical Release under the caption "Treasury Constant Maturities" for the
maturity (rounded to the nearest month) corresponding to the remaining life to
maturity, as of the payment date of the principal being redeemed or paid.  If no
maturity exactly corresponds to such maturity, yields for the two published
maturities most closely corresponding to such maturity shall be calculated
pursuant to the immediately preceding sentence and the Reinvestment Rate shall
be interpolated or extrapolated from such yields on a straight-line basis,
rounding in each of such relevant periods to the nearest month.  For the
purposes of calculating the Reinvestment Rate, the most recent Statistical
Release published prior to the date of determination of the Make-Whole Amount
shall be used.

          "STATISTICAL RELEASE" means the statistical release designated
"H.15(519)" or any successor publication which is published weekly by the
Federal Reserve System and which establishes yields on actively traded United
States government securities adjusted to constant maturities, or, if such
statistical release is not published at the time of any determination under the
Indenture, then such other reasonably comparable index which shall be designated
by the Issuer.

     SECTION 1.02   CREATION OF THE DEBT SECURITIES.  In accordance with Section
301 of the Original Indenture, the Issuer hereby creates the Notes as a separate
series of its debt securities issued pursuant to the Indenture.  The Notes shall
be issued in an aggregate principal amount not to exceed $100,000,000.


                                          3



     SECTION 1.03   FORM OF THE DEBT SECURITIES.  The Notes will be represented
by a single fully-registered global note in book-entry form, without coupons,
registered in the name of the nominee of DTC. The Notes shall be in the form of
Exhibit A attached hereto.  So long as DTC, or its nominee, is the registered
owner of a Global Note, DTC or its nominee, as the case may be, will be
considered the sole owner or holder of the notes represented by such Global Note
for all purposes under the Indenture.  Ownership of beneficial interests in the
Global Note will be shown on, and transfers thereof will be effected only
through, records maintained by DTC (with respect to beneficial interests of
participants) or by participants or persons that hold interests through
participants (with respect to beneficial interests of beneficial owners).

     SECTION 1.04   TERMS AND CONDITIONS OF THE DEBT SECURITIES.  The Notes
shall be governed by all the terms and conditions of the Original Indenture, as
supplemented by this Fifth Supplemental Indenture, and in particular, the
following provisions shall be terms of the Notes:

     (a)  OPTIONAL REDEMPTION.  The Issuer may redeem the Notes at any time at
the option of the Issuer, in whole or from time to time in part, at a redemption
price equal to the Redemption Price.

     If notice has been given as provided in the Original Indenture and funds
for the redemption of any Notes called for redemption shall have been made
available on the Redemption Date referred to in such notice, such Notes will
cease to bear interest on the date fixed for such redemption specified in such
notice and the only right of the Holders of the Notes will be to receive payment
of the Redemption Price.

     Notice of any optional redemption of any Notes will be given to Holders at
their addresses, as shown in the Security Register, not more than 60 nor less
than 30 days prior to the date fixed for redemption.  The notice of redemption
will specify, among other items, the Redemption Price and the principal amount
of the Notes held by such Holder to be redeemed.

     If less than all the Notes are to be redeemed at the option of the Issuer,
the Issuer will notify the Trustee at least 45 days prior to giving notice of
redemption (or such shorter period as is satisfactory to the Trustee) of the
aggregate principal amount of Notes to be redeemed and their Redemption Date. 
The Trustee shall select, in such manner as it shall deem fair and appropriate,
Notes to be redeemed in whole or in part.

     (b)  PAYMENT OF PRINCIPAL AND INTEREST.  Principal and interest payments on
interests represented by a Global Note will be made to DTC or its nominee, as
the case may be, as the registered owner of such Global Note.  All payments of
principal and interest in respect of the Notes will be made by the Issuer in
immediately available funds.

     (c)  APPLICABILITY OF DEFEASANCE OR COVENANT DEFEASANCE.  The provisions of
Article 14 of the Original Indenture shall apply to the Notes.


                                     4



                                     ARTICLE TWO

or impaired thereby.

                                 6 3/4% NOTES DUE 2008

          Duke Realty Limited Partnership, an Indiana limited partnership (the
"Issuer," which term includes any successor under the Indenture hereinafter
referred to), for value received, hereby promises to pay to Cede & Co. or its
registered assigns, the principal sum of One Hundred Million Dollars on May 30,
2008 (the "Maturity Date"), and to pay interest thereon from June 2, 1998 (or
from the most recent interest payment date to which interest has been paid or
duly provided for), semi-annually on May 30 and November 30 of each year (each,
an "Interest Payment Date"), commencing on November 30, 1998, and on the
Maturity Date, at the rate of 6 3/4% per annum, until payment of said principal
sum has been made or duly provided for.

          The interest so payable and punctually paid or duly provided for on
any Interest Payment Date and on the Maturity Date will be paid to the Holder in
whose name this Note (or 


                                  A-1




one or more predecessor Notes) is registered at the close of business on the 
"Record Date" for such payment, which will be 15 days (regardless of whether 
such day is a Business Day (as defined below)) prior to such payment date or 
the Maturity Date, as the case may be.  Any interest not so punctually paid 
or duly provided for shall forthwith cease to be payable to the Holder on 
such record date, and shall be paid to the Holder in whose name this Note (or 
one or more predecessor Notes) is registered at the close of business on a 
subsequent record date for the payment of such defaulted interest (which 
shall be not less than five Business Days (as defined below) prior to the 
date of the payment of such defaulted interest) established by notice given 
by mail by or on behalf of the Issuer to the Holders of the Notes not less 
than 15 days preceding such subsequent record date. Interest on this Note 
will be computed on the basis of a 360-day year of twelve 30-day months.

          The principal of this Note payable on the Maturity Date will be 
paid against presentation and surrender of this Note at the office or agency 
of the Issuer maintained for that purpose in The Borough of Manhattan, The 
City of New York.  The Issuer hereby initially designates the Corporate Trust 
Office of the Trustee in the City of New York as the office to be maintained 
by it where Notes may be presented for payment, registration of transfer, or 
exchange and where notices or demands to or upon the Issuer in respect of the 
Notes or the Indenture referred to on the reverse hereof may be served.

          Interest payable on this Note on any Interest Payment Date and on 
the Maturity Date, as the case may be, will be the amount of interest accrued 
from and including the immediately preceding Interest Payment Date (or from 
and including June 2, 1998 in the case of the initial Interest Payment Date) 
to but excluding the applicable Interest Payment Date or the Maturity Date, 
as the case may be.  If any Interest Payment Date or the Maturity Date falls 
on a day that is not a Business Day (as defined below), the required payment 
of interest or principal or both, as the case may be, will be made on the 
next Business Day with the same force and effect as if it were made on the 
date such payment was due and no interest will accrue on the amount so 
payable for the period from and after such Interest Payment Date or the 
Maturity Date, as the case may be. "Business Day" means any day, other than a 
Saturday or a Sunday, on which banking institutions in The City of New York 
are open for business.

          Payments of principal and interest in respect of this Note will be 
made by wire transfer of immediately available funds in such coin or currency 
of the United States of America as at the time of payment is legal tender for 
the payment of public and private debts.

          Reference is made to the further provisions of this Note set forth 
on the reverse hereof.  Such further provisions shall for all purposes have 
the same effect as though fully set forth at this place.

          This Note shall not be entitled to the benefits of the Indenture 
referred to on the reverse hereof or be valid or become obligatory for any 
purpose until the certificate of authentication hereon shall have been signed 
by the Trustee under such Indenture. 


                                       A-2

thereto.  This security is one of a series designated as the 63/4% Notes due May
30, 2008 of the Issuer, limited in aggregate principal amount to $100,000,000.

          In case an Event of Default with respect to this security shall have
occurred and be continuing, the principal hereof and Make-Whole Amount, if any,
may be declared, and upon such declaration shall become, due and payable, in the
manner, with the effect, and subject to the conditions provided in the
Indenture.

          The Issuer may redeem this security at any time at the option of the
Issuer, in whole or in part, at a redemption price equal to the sum of (i) the
principal amount of this security being redeemed plus accrued interest thereon
to the Redemption Date and (ii) the Make-Whole Amount, if any, with respect to
this security (the "Redemption Price").  Notice of any optional redemption of
any Securities will be given to Holders at their addresses, as shown in the
Security Register, not more than 60 nor less than 30 days prior to the date
fixed for redemption.  The notice of redemption will specify, among other items,
the Redemption Price and the principal amount of the Securities held by such
Holder to be redeemed.        

          The Indenture contains provisions permitting the Issuer and the
Trustee, with the consent of the Holders of not less than a majority of the
aggregate principal amount of the Securities at the time Outstanding of all
series to be affected (voting as one class), evidenced as provided in the
Indenture, to execute supplemental indentures adding any provisions to or
changing in any manner or eliminating any of the provisions of the Indenture or
of any supplemental indenture or modifying in any manner the rights of the
Holders of the Securities of each series; provided, however, that no such
supplemental indenture shall, without the consent of the Holder of each Security
so affected, (i) change the Stated Maturity of the principal of (or 


                                 A-5



premium, if any, on) or any installment of principal of or interest on, any 
Security, or reduce the principal amount thereof or the rate or amount of 
interest thereon or any premium payable upon the redemption thereof, or 
adversely affect any right of repayment at the option of the Holder of any 
Security, or change any Place of Payment where, or the currency or 
currencies, currency unit or units or composite currency or currencies in 
which, any Security or any premium or the interest thereon is payable, or 
impair the right to institute suit for the enforcement of any such payment on 
or after the Stated Maturity thereof, or (ii) reduce the aforesaid percentage 
of Securities, the Holders of which are required to consent to any such 
supplemental indenture, or (iii) reduce the percentage of Securities, the 
Holders of which are required to consent to any waiver of compliance with 
certain provisions of the Indenture or any waiver of certain defaults 
thereunder.  It is also provided in the Indenture that, with respect to 
certain defaults or Events of Default regarding the Securities of any series, 
the Holders of a majority in aggregate principal amount outstanding of the 
Securities of such series (or, in the case of certain defaults or Events of 
Default, all series of Securities) may on behalf of the Holders of all the 
Securities of such series (or all of the Securities, as the case may be) 
waive any such past default or Event of Default and its consequences, prior 
to any declaration accelerating the maturity of such Securities, or, subject 
to certain conditions, may rescind a declaration of acceleration and its 
consequences with respect to such Securities. Any such consent or waiver by 
the Holder of this security (unless revoked as provided in the Indenture) 
shall be conclusive and binding upon such Holder and upon all future Holders 
and owners of the security and any securities that may be issued in exchange 
or substitution herefor, irrespective of whether or not any notation thereof 
is made upon this security or such other securities.

          No reference herein to the Indenture and no provision of this 
security or of the Indenture shall alter or impair the obligation of the 
Issuer, which is absolute and unconditional, to pay the principal of and any 
Make-Whole Amount and interest on this security in the manner, at the 
respective times, at the rate and in the coin or currency herein prescribed.

          This security is issuable only in registered form without coupons 
in denominations of $1,000 and integral multiples thereof.  Securities may be 
exchanged for a like aggregate principal amount of securities of this series 
of other authorized denominations at the office or agency of the Issuer in 
The Borough of Manhattan,  The City of New York, in the manner and subject to 
the limitations provided in the Indenture, but without the payment of any 
service charge except for any tax or other governmental charge imposed in 
connection therewith.

          Upon due presentment for registration of transfer of Securities at 
the office or agency of the Issuer in The Borough of Manhattan, The City of 
New York, one or more new Securities of the same series of authorized 
denominations in an equal aggregate principal amount will be issued to the 
transferee in exchange therefor, subject to the limitations provided in the 
Indenture, without charge except for any tax or other governmental charge 
imposed in connection therewith.

          The Issuer, the Trustee or any authorized agent of the Issuer or 
the Trustee may deem and treat the Person in whose name this security is 
registered as the absolute owner of this security (whether or not this 
security shall be overdue and notwithstanding any notation of ownership or 
other writing hereon), for the purpose of receiving payment of, or on account 
of, 


                                      A-6



the principal hereof and Make-Whole Amount, if any, and subject to the 
provisions on the face hereof, interest hereon, and for all other purposes, 
and neither the Issuer nor the Trustee nor any authorized agent of the Issuer 
or the Trustee shall be affected by any notice to the contrary.

          The Indenture and each Security shall be deemed to be a contract under
the laws of the State of New York, and for all purposes shall be construed in
accordance with the laws of such state, except as may otherwise be required by
mandatory provisions of law.

          Capitalized terms used herein which are not otherwise defined shall
have the respective meanings assigned to them in the Indenture and all
indentures supplemental thereto relating to this security.
