Item 5. OTHER EVENTS.

         On March 1, 1999, Duke Realty Investments, Inc. ("Duke") announced that
it entered into an Agreement and Plan of Merger, dated as of February 28, 1999
(the "Merger Agreement"), with Weeks Corporation ("Weeks"), pursuant to which
Weeks will merge with and into Duke. In the merger, each outstanding share of
common stock of Weeks will be converted into the right to receive 1.38 shares of
common stock of Duke; each outstanding share of 8.0% Series A Cumulative
Redeemable Preferred Stock of Weeks will be converted into the right to receive
one preference share of Duke representing 1/1000 of a share of 8.0% Series F
Cumulative Redeemable Preferred Stock of Duke; and each outstanding share of
8.625% Series D Cumulative Redeemable Preferred Stock of Weeks will be converted
into the right to receive one preference share of Duke representing 1/1000 of a
share of 8.625% Series H Cumulative Redeemable Preferred Stock of Duke. The
terms of the Duke preference shares to be issued in the Merger will be identical
to the terms of the Weeks Series A and Series D preferred stock. Weeks'
principal operating subsidiary, Weeks Realty, L.P. (the "Weeks Operating
Partnership"), will be merged with and into Duke Realty Limited Partnership (the
"Duke Operating Partnership"). The transactions are expected to close in the
second or third quarter of 1999, subject to receipt of necessary approvals by
the Duke and Weeks shareholders and satisfaction of customary closing
conditions.

         Holders representing approximately 2% of the outstanding common 
stock of Weeks have entered into voting agreements, agreeing to vote their 
shares in favor of the transactions. Holders representing approximately 5% of 
the outstanding common stock of Duke have entered into voting agreements, 
agreeing to vote their shares in favor of the transactions. The requisite 
approvals of the partners of Duke Operating Partnership and Weeks Operating 
Partnership to the transactions have been obtained. Weeks has agreed with 
Duke that if the Merger Agreement is terminated under certain circumstances, 
Weeks will pay Duke certain fees and expenses. Duke has agreed with Weeks

AGREEMENT AND PLAN OF MERGER (the "AGREEMENT"), dated as of February 28, 1999,
by and between DUKE REALTY INVESTMENTS, INC., an Indiana corporation ("DUKE"),
and WEEKS CORPORATION, a Georgia corporation ("WEEKS").

                                    RECITALS

         A. The Boards of Directors of Duke and Weeks each have determined that
it is advisable and in the best interest of their respective companies and
shareholders that upon the terms and subject to the conditions set forth in this
Agreement, Weeks will merge with and into Duke, with Duke being the surviving
corporation, in a merger (the "REIT MERGER") in which each issued and
outstanding share of common stock, par value $.01 per share, of Weeks (the
"WEEKS COMMON STOCK"), each issued and outstanding share of 8.0% Series A
Cumulative Redeemable Preferred Stock, par value $.01 per share, of Weeks (the
"WEEKS SERIES A PREFERRED STOCK") and each issued and outstanding share, if any,
of 8.625% Series D Cumulative Redeemable Preferred Stock, par value $.01 per
share, of Weeks (the "WEEKS SERIES D PREFERRED STOCK" and together with the
Weeks Series A Preferred Stock, the "WEEKS PREFERRED STOCK") will be converted
into the right to receive the applicable Merger Consideration (as defined
below).

         B. Duke, as managing general partner of Duke Limited Partnership, an
Indiana limited partnership ("DUKE OP"), and Weeks, as general partner (through
a wholly owned subsidiary) of Weeks, L.P., a Georgia limited partnership ("WEEKS
OP"), each has determined that it is advisable and in the best interest of their
respective partnerships and partners that upon the terms and subject to the
conditions set forth in an agreement and plan of merger between Duke OP and
Weeks OP executed on the date hereof, a copy of which is attached as Exhibit A
hereto (the "OP MERGER AGREEMENT"), Weeks OP will merge with and into Duke OP
with Duke OP being the surviving partnership in such merger (the "OP MERGER").

         C. The parties intend that for federal income tax purposes the REIT
Merger will qualify as a tax-free reorganization under Section 368(a) of the
Internal Revenue Code of 1986, as amended (the "CODE"), and that, following the
REIT Merger, Duke will continue to be subject to taxation as a real estate
investment trust (a "REIT") within the meaning of the Code.

         D. Contemporaneously with the execution and delivery of this Agreement,
(i) certain holders of Weeks Common Stock named in Schedule A hereto and certain
holders of limited partnership interests in Weeks OP named in Schedule A hereto
have entered into agreements, each substantially in the form of Exhibit B hereto
(the "WEEKS VOTING AGREEMENTS"), with Duke and Duke OP pursuant to which, among
other things, those holders have granted to Duke irrevocable proxies to vote
their shares and partnership interests in favor of the REIT Merger, this
Agreement, the OP Merger, the OP Merger Agreement and the other transactions
contemplated hereby and thereby and against any competing proposal, and (ii)
certain holders of Duke Common Stock named in Schedule B hereto and certain
holders of limited partnership interests in Duke OP named in Schedule B hereto
have entered into agreements with Weeks and Weeks OP, each substantially in the
form of Exhibit C hereto (the "DUKE VOTING AGREEMENTS"), pursuant to which,
among other things, those holders have granted to Weeks irrevocable proxies to
vote their shares and partnership interests in favor of the REIT Merger, this
Agreement, the OP Merger, the OP Merger Agreement and the other transactions
contemplated hereby and thereby and against any competing proposal.

         E. Contemporaneously with the execution and delivery of this Agreement,
the persons named in Schedule C hereto (collectively the "SERVICES COMPANIES
OWNERS") have entered into an option agreement, a copy of which is attached as
Exhibit D hereto (the "WEEKS SERVICES COMPANIES OPTION AGREEMENT"), with MWSB,
Inc. (the "OPTION HOLDER") pursuant to which the Weeks Services Companies Owners
have granted the Option Holder an option to acquire all of the interests of the
Weeks Services 


<PAGE>

Companies Owners in Weeks Realty Services, Inc. and Weeks Construction 
Services, Inc. (together, the "WEEKS SERVICES COMPANIES").

                                    AGREEMENT

         In consideration of the representations, warranties, covenants and
agreements contained in this Agreement, the parties agree as follows:

                                   ARTICLE I

                                 THE REIT MERGER
                                 ---------------

         Section 1.1. THE REIT MERGER.

         (a) Upon the terms and subject to the conditions set forth in this
Agreement, at the Effective Time (as hereinafter defined), Weeks shall be merged
with and into Duke in accordance with the Indiana Business Corporation Law (the
"IBCL") and the Georgia Business Corporation Code (the "GBCC," and together with
the IBCL, the "GOVERNING LAWS"), whereupon the separate corporate existence of
Weeks shall cease and Duke shall continue as the surviving corporation (the
"SURVIVING CORPORATION").

         (b) The REIT Merger shall have the effects set forth in the Governing
Laws. Accordingly, from and after the Effective Time, the Surviving Corporation
shall possess all the rights, privileges, powers and franchises and be subject
to all of the restrictions, disabilities, liabilities and duties of Duke and
Weeks.

         Section 1.2. CLOSING. The closing of the REIT Merger (the "CLOSING")
will take place at 10:00 a.m. New York City time on the second business day
after satisfaction or waiver of the conditions set forth in Article VI (the
"CLOSING DATE"), at the offices of Rogers & Wells LLP, 200 Park Avenue, New
York, New York 10166, unless another date or place is agreed to in writing by
the parties.

         Section 1.3. EFFECTIVE TIME. On the Closing Date, the parties shall
execute and file Articles of Merger or other appropriate documents in accordance
with the Governing Laws, and shall make all other filings or recordings required
with respect to the REIT Merger under the Governing Laws. The REIT Merger shall
become effective one day after the day a certificate of merger or other
appropriate documents for the OP Merger have been duly filed with the Secretary
of State of Indiana and the Secretary of State of Georgia, or at such other time
or times as may be agreed by Duke and Weeks and specified in the Articles of
Merger (the time the REIT Merger becomes effective being the "EFFECTIVE TIME"),
it being understood that the parties shall cause the Effective Time to occur as
soon as practicable after the Closing Date but in any event at least one day
after the effective time of the OP Merger.

         Section 1.4. CHARTER AND BY-LAWS. The articles of incorporation and
by-laws of Duke, amended and restated substantially in the forms set forth in
Exhibits E and F hereto, shall become the articles of incorporation (the
"CHARTER") and by-laws (the "BY-LAWS") of the Surviving Corporation upon the
Effective Time until further amended in accordance with applicable Indiana law;
PROVIDED, HOWEVER, that if the Duke Special Charter Proposal (as defined below)
is not approved at the Duke Shareholders Meeting (as defined in Section 5.1(b))
by the affirmative vote of at least 80% of Duke's issued and outstanding shares
of capital stock ("80% DUKE APPROVAL"), the Charter and By-laws upon the
Effective Time shall be substantially in the forms set forth in Exhibits G and H
hereto until further amended in accordance with applicable Indiana law. The
"DUKE SPECIAL CHARTER PROPOSAL" is the proposal, to be presented at the Duke
Shareholders Meeting, to amend Duke's Charter to (i) increase the size of Duke's

                                       2
<PAGE>

Board of Directors to a minimum of five and a maximum of 23 and (ii) delete the
references contained in Article XII of Duke's Charter to Section 7.01 of the
Charter.

         Section 1.5. DIRECTORS. Immediately following the Effective Time, the
Board of Directors of the Surviving Corporation (the "BOARD") and certain
committees of the Board shall consist of the persons named on Schedule D hereto,
each of whom shall be a member of the class indicated on Schedule D; PROVIDED,
HOWEVER, that if the Duke Special Charter Proposal is not approved at the Duke
Shareholder Meeting by the 80% Duke Approval, the Board and certain committees
of the Board shall consist immediately following the Effective Time of the

         Section 2.1. EFFECT ON CAPITAL STOCK

         (a) CAPITAL STOCK OWNED BY WEEKS OR ITS SUBSIDIARIES. As of the
Effective Time, any shares of capital stock of Weeks that are owned by Weeks or
any Weeks Subsidiary automatically shall be cancelled and retired and all rights
with respect thereto shall cease to exist, and no consideration shall be
delivered in exchange therefor.

         (b) CONVERSION OF WEEKS CAPITAL STOCK INTO DUKE CAPITAL STOCK. At the
Effective Time, except as provided in Section 2.1(a), (i) each issued and
outstanding share of Weeks Common Stock shall be converted by virtue of the REIT
Merger, automatically and without any action on the part of the holder thereof,
into the right to receive from the Surviving Corporation 1.38 (the "EXCHANGE
RATIO"") fully paid and nonassessable shares of common stock, par value $.01 per
share, of Duke ("DUKE COMMON STOCK"), (ii) each issued and outstanding share of
Weeks Series A Preferred Stock shall be converted by virtue of the REIT Merger,
automatically and without any action on the part of the holder thereof, into the
right to receive from the Surviving Corporation one fully paid and nonassessable

of 8.0% Series F Cumulative Redeemable Preferred Stock, par value $.01 per
share, of Duke ("DUKE SERIES F PREFERRED STOCK") and (iii) each issued and
outstanding share of Weeks Series D Preferred Stock (if any) shall be converted,
by virtue of the REIT Merger, automatically and without any action on the part
of the holder thereof, into the right to receive from the Surviving Corporation
one fully paid and nonassessable preference share (a "SERIES H PREFERENCE
SHARE", and together with the Series F Preference Shares, the "NEW DUKE
PREFERENCE SHARES"), representing 1/1000 of a share of 8.625% Series H
Cumulative Redeemable Preferred Stock, par value $0.01 per share, of Duke ("DUKE
SERIES H PREFERRED STOCK", and together with the Duke Series F Preferred Stock,
the "NEW DUKE PREFERRED STOCK"). At the Effective Time, all shares of Weeks
Common Stock and



                                       3
<PAGE>

Weeks Preferred Stock outstanding immediately prior to the Effective Time shall
cease to be outstanding and automatically shall be cancelled and retired and all
rights with respect thereto shall cease to exist, and each holder of a
certificate representing any shares of Weeks Common Stock or Weeks Preferred
Stock (a "CERTIFICATE") shall cease to have any rights with respect thereto,
except the right to receive, upon surrender of such Certificate in accordance
with Section 2.2(c), a certificate or certificates representing the shares of
Duke Common Stock or New Duke Preference Shares, as applicable, into which those
shares are converted pursuant to this Section 2.1(b) and any cash in lieu of
fractional shares of Duke Common Stock to be issued or paid in consideration
therefor upon surrender of such certificate (the "MERGER CONSIDERATION") and any
dividends or other distributions to which such holder is entitled pursuant to
Section 2.2(d), in each case without interest and less any required withholding
taxes. Notwithstanding the foregoing, the rights of each stockholder of the
Surviving Corporation under this Section 2.1 will be subject to the ownership
limitations and other related provisions contained in the Charter.

         (c) SHARES OF DUKE CAPITAL STOCK. Upon the Effective Time, each share
of capital stock of Duke outstanding immediately prior to the Effective Time
shall remain outstanding and shall represent one share of validly issued, fully
paid and nonassessable capital stock of the same class and designation.

         Section 2.2. EXCHANGE OF CERTIFICATES.

         (a) EXCHANGE AGENT. Prior to the Effective Time, Duke shall appoint a
bank or trust company that is reasonably acceptable to Weeks to act as exchange
agent (the "EXCHANGE AGENT") for the exchange of the Merger Consideration for
Certificates representing issued and outstanding Weeks Common Stock and Weeks
Preferred Stock.

         (b) DUKE TO PROVIDE MERGER CONSIDERATION. Duke shall provide, or cause
to be provided, to the Exchange Agent on and after the Effective Time from time
to time as required pursuant to Section 2.2(c) and 2.2(g), for the benefit of
the holders of Weeks Common Stock and Weeks Preferred Stock, certificates
representing the shares of Duke Common Stock and New Duke Preferred Stock into
which the issued and outstanding shares of Weeks Common Stock and Weeks
Preferred Stock are converted pursuant to Section 2.1(b), together with the cash
payable in respect of fractional shares pursuant to Section 2.2(g).

         (c) EXCHANGE PROCEDURE. As soon as reasonably practicable after the
Effective Time, the Exchange Agent shall mail to each holder of record of a
Certificate or Certificates whose shares were converted into the right to
receive the Merger Consideration pursuant to Section 2.1, (i) a letter of
transmittal (which shall specify that delivery shall be effected, and risk of
loss and title to the Certificates shall pass, only upon delivery of the
Certificates to the Exchange Agent and shall be in a form and have such other
provisions as Duke may reasonably specify) and (ii) instructions for use in
effecting the surrender of the Certificates, in exchange for the applicable
Merger Consideration. Upon surrender of a Certificate for cancellation to the
Exchange Agent or to such other agent or agents as may be appointed by Duke,
together with such letter of transmittal, duly executed, and such other
documents as may reasonably be required by the Exchange Agent, the holder of
such Certificate shall be entitled to receive in exchange therefor the
applicable Merger Consideration and any dividends or other distributions to
which such holder is entitled pursuant to Section 2.2(d), and the Certificate so
surrendered shall forthwith be cancelled. In the event of a transfer of
ownership of Weeks Common Stock or Weeks Preferred Stock which is not registered
in the transfer records of Weeks, payment may be made to a person other than the
person in whose name the Certificate so surrendered is registered if such
Certificate shall be properly endorsed or otherwise be in proper form for
transfer and the person requesting such payment either shall pay any transfer or
other taxes required by reason of such payment being made to a person other than
the registered holder of such Certificate or establish to the satisfaction of
Duke that such tax or taxes have

                                       4
<PAGE>

been paid or are not applicable. Until surrendered as contemplated by this
Section 2.2, each Certificate shall be deemed at any time after the Effective
Time to represent only the right to receive upon such surrender the applicable
Merger Consideration, without interest, into which the shares theretofore
represented by such Certificate shall have been converted pursuant to Section
2.1 and any dividends or other distributions to which such holder is entitled
pursuant to Section 2.2(d). No interest will be paid or will accrue on the
applicable Merger Consideration upon the surrender of any Certificate or on any
cash payable pursuant to Section 2.2(d) or Section 2.2(g).

         (d) RECORD DATES; DISTRIBUTIONS WITH RESPECT TO UNEXCHANGED SHARES.

         (i) To the extent reasonably necessary to ensure satisfaction of the
requirements of Section 857(a)(1) of the Code for the taxable year of Weeks
ending at the Effective Time, Weeks shall declare a dividend (the "FINAL WEEKS
DIVIDEND") to holders of shares of Weeks Common Stock, the record date for which
shall be the close of business on the last business day prior to the Effective
Time, in an amount equal to the minimum dividend sufficient to permit Weeks to
satisfy such requirements. If Weeks determines it necessary to declare the Final
Weeks Dividend, it shall notify Duke at least ten (10) days prior to the date
for the Weeks Shareholders Meeting (as defined in Section 5.1(b)), and Duke
shall declare a dividend per share to holders of Duke Common Stock, the record
date for which shall be the close of business on the last business day prior to
the Effective Time, in an amount per share equal to the quotient obtained by
dividing (x) the Final Weeks Dividend per share of Weeks Common Stock paid by
Weeks by (y) the Exchange Ratio. The dividends payable hereunder to holders of
Weeks Common Stock shall be paid upon presentation of the Certificates of Weeks
Common Stock for exchange in accordance with this Article II.

         (ii) No dividends or other distributions with respect to Duke Common
Stock or New Duke Preferred Stock with a record date after the Effective Time
shall be paid to the holder of any unsurrendered Certificate with respect to the
shares represented thereby, and no cash payment in lieu of fractional shares
shall be paid to any such holder pursuant to Section 2.2(g), in each case until
the surrender of such Certificate in accordance with this Article II. Subject to
the effect of applicable abandoned property, escheat or similar laws, following
surrender of any such Certificate there shall be paid to the holder of such
Certificate without interest, (A) at the time of such surrender, the amount of
any cash payable in lieu of any fractional share of Weeks Common Stock to which
such holder is entitled pursuant to Section 2.2(g) and (B) if such Certificate
is exchangeable for one or more whole shares of Duke Common Stock, or New Duke
Preferred Stock, (x) at the time of such surrender, the amount of dividends or
other distributions with a record date after the Effective Time theretofore paid
with respect to such whole shares of Duke Common Stock or New Duke Preferred
Stock, and (y) at the appropriate payment date, the amount of dividends or other
distributions with a record date after the Effective Time but prior to such
surrender and with a payment date subsequent to such surrender payable with
respect to such whole shares of Duke Common Stock or New Duke Preferred Stock.

         (e) NO FURTHER OWNERSHIP RIGHTS IN WEEKS CAPITAL STOCK. All Merger
Consideration paid upon the surrender of Certificates in accordance with the
terms of this Article II (and any cash paid pursuant to Section 2.2(g)) shall be
deemed to have been paid in full satisfaction of all rights pertaining to the
shares of Weeks Common Stock and Weeks Preferred Stock theretofore represented
by such Certificates; subject, however, to the obligation of Weeks to pay,
without interest, any dividends or make any other distributions with a record
date prior to the Effective Time which may have been declared or made by Weeks
on such shares in accordance with the terms of this Agreement or prior to the
date of this Agreement and which remain unpaid at the Effective Time and have
not been paid prior to such surrender, and there shall be no further
registration of transfers on the stock transfer books of Weeks of the shares of
Weeks Common Stock or Weeks Preferred Stock which were outstanding immediately
prior



                                       5
<PAGE>

to the Effective Time. If, after the Effective Time, Certificates are properly
presented to the Surviving Corporation they shall be cancelled and exchanged as
provided in this Article II.

         (f) UNCLAIMED MERGER CONSIDERATION. Any portion of the Merger
Consideration delivered to the Exchange Agent pursuant to this Agreement that
remains unclaimed for six months after the Effective Time shall be redelivered
by the Exchange Agent to the Surviving Corporation, upon demand, and any holders
of Certificates who have not theretofore complied with Section 2.2(b) shall
thereafter look only to the Surviving Corporation for delivery of the Merger
Consideration, subject to applicable abandoned property, escheat and other
similar laws. The Surviving Corporation shall have no liability to any holder of
shares of Weeks Common Stock or Weeks Preferred Stock for Merger Consideration
delivered to a public official pursuant to any applicable abandoned property,
escheat or similar law. Any Merger Consideration remaining unclaimed by any
holder of shares of Weeks Common Stock or Weeks Preferred Stock on the day
immediately prior to the time such amounts otherwise would escheat to or become
the property of any governmental entity shall, to the extent permitted by law,
become the property of the Surviving Corporation, free and clear of any claim or
interest of any Persons previously entitled thereto.

         (g) NO FRACTIONAL SHARES.

                  (i) No certificates or scrip representing fractional shares of
Duke Common Stock shall be issued upon the surrender for exchange of
Certificates, and such fractional share interests will not entitle the owner
thereof to vote, to receive dividends or to any other rights of a stockholder of
Duke.

                  (ii) Notwithstanding any other provision of this Agreement,
each holder of shares of Weeks Common Stock who would otherwise have been
entitled to receive a fraction of a share of Duke Common Stock (after taking
into account all Certificates delivered by such holder) shall receive, upon
surrender of such holder's Certificates in accordance with Section 2.1, a cash
payment in lieu of such fractional shares of Duke Common Stock equal to the same
fractional proportion of the arithmetic mean of the closing sales price of a
share of Duke Common Stock on the New York Stock Exchange (the "NYSE") on each
of the ten trading days immediately preceding the Closing Date.

         (h) WITHHOLDING. The Surviving Corporation or the Exchange Agent shall
be entitled to deduct and withhold from the Merger Consideration otherwise
payable pursuant to this Agreement to any holder of shares of Weeks Common Stock
or Weeks Preferred Stock such amounts as the Surviving Corporation or the
Exchange Agent is required to deduct and withhold with respect to the making of
such payment under the Code, or any provision of state, local or foreign tax
law. To the extent that amounts are so withheld by the Surviving Corporation or
the Exchange Agent, such withheld amounts shall be treated for all purposes of
this Agreement as having been paid to the holder of the shares of Weeks Common
Stock or Weeks Preferred Stock, as the case may be, in respect of which such
deduction and withholding was made by the Surviving Corporation or the Exchange
Agent.

         (i) NO DISSENTERS' RIGHTS. No dissenters' or appraisal rights shall be
available with respect to the REIT Merger.

                                   ARTICLE III

         (a) ORGANIZATION, STANDING AND CORPORATE POWER OF WEEKS. Weeks is a
corporation duly organized and validly existing under the laws of Georgia and
has the requisite corporate power and authority to carry on its business as now
being conducted. Weeks is duly qualified or licensed to do business and is in
good standing in each jurisdiction in which the nature of its business or the
ownership, leasing of its properties or management of properties for others
makes such qualification or licensing necessary, other than in such
jurisdictions where the failure to be so qualified or licensed, individually or
in the aggregate, would not have a material adverse effect on the business,
properties, financial condition or results of operations of Weeks and the Weeks
Subsidiaries taken as a whole (a "WEEKS MATERIAL ADVERSE EFFECT").

         (b) WEEKS SUBSIDIARIES; INTERESTS IN OTHER PERSONS.

Subsidiary, including Weeks OP, is duly qualified or licensed to do business and
is in good standing in each jurisdiction in which the nature of its business or

in the aggregate, would not have a Weeks Material Adverse Effect.


                  (ii) Except for the capital stock of, or other equity
interests in, the Weeks Subsidiaries and the other interests disclosed in

and Weeks OP have filed all required reports, schedules, forms, statements and
other documents with the SEC since January 1, 1995 and August 4, 1997,
respectively (collectively, the "WEEKS SEC DOCUMENTS"). All of the Weeks SEC
Documents (other than preliminary materials or materials that were subsequently
amended), as of their respective filing dates, complied in all material respects
with all applicable requirements of the Securities Act of 1933, as amended (the
"SECURITIES ACT") and the Exchange Act and, in each case, the rules and
regulations promulgated thereunder applicable to such Weeks SEC Documents. None
of the Weeks SEC Documents at the time of filing contained any untrue statement
of a material fact or omitted to state any material fact required to be stated
therein or necessary in order to make the statements therein, in light of the
circumstances under which they were made, not misleading, except to the extent
such statements have been amended, modified or superseded by later filed Weeks
SEC Documents. None of the Weeks SEC Documents is the subject of any
confidential treatment request by Weeks or Weeks OP. Section 3.1(e) of the Weeks
Disclosure Letter lists all of the Weeks SEC Documents filed with the SEC since
January 1, 1998. The consolidated financial statements of Weeks and Weeks OP, as
applicable, included in the Weeks SEC Documents complied as to form in all
material respects with applicable accounting requirements and the published
rules and regulations of the SEC with respect thereto, have been prepared in
accordance with generally accepted accounting principles ("GAAP") (except, in
the case of interim financial statements, as permitted by the applicable rules
and regulations of the SEC) applied on a consistent basis during the periods
involved (except as may be indicated in the notes thereto) and fairly presented
in all material respects, in accordance with the applicable requirements of
GAAP, the consolidated financial position of Weeks and the Weeks Subsidiaries
taken as a whole, as of the dates thereof and the consolidated results of
operations and cash flows for the periods then ended (subject, in the case of
interim financial statements, to normal year-end adjustments). Except as set
forth in the Weeks SEC Documents filed with the SEC prior to the date of this
Agreement, neither Weeks nor any Weeks Subsidiary has any liabilities or
obligations of any nature (whether accrued, absolute, contingent or otherwise)
required by GAAP to be set forth on a consolidated balance sheet of Weeks or in
the notes thereto and which, individually or in the aggregate, would have a
Weeks Material Adverse Effect.

         (f) ABSENCE OF CERTAIN CHANGES OR EVENTS. Except as disclosed in the
Weeks SEC Documents filed with the SEC prior to the date of this Agreement,
since December 31, 1997 (the "WEEKS FINANCIAL STATEMENT DATE") and to the date
of this Agreement, Weeks and the Weeks Subsidiaries have conducted their
business only in the ordinary course and there has not been (i) any change that
would have a Weeks Material Adverse Effect (a "WEEKS MATERIAL ADVERSE CHANGE"),
nor has there been any occurrence or circumstance that with the passage of time
would reasonably be expected to result in a Weeks Material Adverse Change, (ii)
any declaration, setting aside or payment of any dividend or other



                                       10
<PAGE>

distribution (whether in cash, stock or property) with respect to any of Weeks'
capital stock or any Weeks OP Units, except for (A) regular quarterly dividends
(in the case of Weeks) not in excess of $.505 per share of Weeks Common Stock
and regular quarterly dividends on Weeks Series A Preferred Stock not in excess
of $.50 per share of Weeks Series A Preferred Stock, (B) the payment of a
preferred stock purchase right dividend pursuant to a Rights Agreement between
Weeks and Wachovia Bank, N.A. dated May 20, 1998 (the "RIGHTS AGREEMENT"), (C)
the Final Weeks Dividend and the corresponding Weeks OP distribution, (D)
regular quarterly distributions (in the case of Weeks OP) of $.505 per Weeks
Common OP Unit, $.50 per Series A Preferred OP Unit, $.50 per Series C Preferred
OP Unit and $.5390625 per Series D Preferred OP Unit and (E) any distributions
by any Weeks Subsidiaries (other than Weeks OP) to other Weeks Subsidiaries or
to Weeks, in each case, with customary record and payment dates, (iii) any
split, combination or reclassification of any of Weeks' capital stock or any
issuance or the authorization of any issuance of any other securities in respect
of, in lieu of or in substitution for, or giving the right to acquire by
exchange or exercise, shares of its capital stock or any issuance of an
ownership interest in, any Weeks Subsidiary, (iv) any damage, destruction or
loss, whether or not covered by insurance, that has or would have a Weeks
Material Adverse Effect, or (v) any change in accounting methods, principles or
practices by Weeks materially affecting its assets, liabilities or business,
except insofar as may have been disclosed in the Weeks SEC Documents filed with
the SEC prior to the date of this Agreement, or required by a change in GAAP.

         (g) LITIGATION. Except as disclosed in the Weeks SEC Documents filed
with the SEC prior to the date of this Agreement, and other than personal injury
and other routine tort litigation arising from the ordinary course of operations
of Weeks and the Weeks Subsidiaries which are covered by adequate insurance,
there is no suit, action or proceeding pending or, to the knowledge of Weeks,
threatened against or affecting Weeks or any Weeks Subsidiary that, individually
or in the aggregate, could reasonably be expected to (i) have a Weeks Material
Adverse Effect or (ii) prevent the consummation of any of the transactions
contemplated herein, nor is there any judgment, decree, injunction, rule or
order of any Governmental Entity or arbitrator outstanding against Weeks or any
Weeks Subsidiary having, or which, insofar as reasonably can be foreseen, in the
future would have, any such effect.

         (h) ABSENCE OF CHANGES IN BENEFIT PLANS; ERISA COMPLIANCE.

                  (i) Except as disclosed in the Weeks SEC Documents filed with
the SEC prior to the date of this Agreement, since the Weeks Financial Statement
Date, there has not been any adoption or amendment in any material respect, or
the undertaking of any additional obligation, by Weeks, any Weeks Subsidiary or
any Weeks ERISA Affiliate (as defined below) of any Weeks Benefit Plan (as
defined below). For purposes of this Agreement, "Weeks Benefit Plan" shall mean
any Employee Plan sponsored or maintained by Weeks, any Weeks Subsidiary or any
Weeks ERISA Affiliate, or with respect to which Weeks, any Weeks Subsidiary or
any Weeks ERISA Affiliate has any obligation to contribute, has liability under
or is otherwise a party to, or which otherwise provides benefits for any current
or former employees, officers, directors or other independent contractors (or
their dependents and beneficiaries) of Weeks or any Weeks Subsidiary. For
purposes of this Agreement, "Weeks ERISA Affiliate" means any entity required to
be aggregated with any of Weeks or any Weeks Subsidiary under Sections 414(b),
(c), (m) or (o) of the Code or Section 4001 of the Employee Retirement Income
Security Act of 1974, as amended ("ERISA"). Section 3.1(h)(i) of the Weeks
Disclosure Letter sets forth each Weeks Benefit Plan.

                  (ii) Except as described in the Weeks SEC Documents filed with
the SEC prior to the date of this Agreement or as would not have a Weeks
Material Adverse Effect, (A) all Weeks Benefit Plans, including any such plan
that is an "employee benefit plan" as defined in Section 3(3) of ERISA, are in
compliance with the terms of such plan and all applicable requirements of law,
including ERISA and the Code and, without limitation, the requirements of ERISA
and all tax rules for which favorable tax


                                       11
<PAGE>

treatment is intended, and (B) there are no liabilities or obligations with
respect to any such Weeks Benefit Plan, whether accrued, contingent or otherwise
(other than obligations by Weeks and the Weeks Subsidiaries to make
contributions, and for such plan to pay benefits and administrative costs,
incurred in the ordinary course), nor to the knowledge of Weeks are any such
liabilities or obligations expected to be incurred. The execution of, and
performance of the transactions contemplated in, this Agreement will not (either
alone or together with the occurrence of any additional or subsequent events)
constitute an event under any Weeks Benefit Plan, policy, program, arrangement
or agreement, trust or loan that will or may result in any payment (whether of
severance pay or otherwise), acceleration, forgiveness of indebtedness, vesting,
distribution, increase in benefits or obligation to fund benefits with respect
to any employee or director, will not result in any "golden parachute payments"
being due (as defined for purposes of Section 280G of the Code), or result in
any breach or violation of, or a default under, any of the Weeks Benefit Plans.
The only severance agreements or severance policies applicable to Weeks or the
Weeks Subsidiaries are the agreements and policies specifically referred to in
Section 3.1(h)(ii) of the Weeks Disclosure Letter.

                  (iii) Without limiting the foregoing, each Weeks Benefit Plan
which is intended to be tax-qualified under Section 401(a) of the Code has been
determined by the IRS to be so qualified and such determination has not been
modified, revoked or limited, and no circumstances have occurred that would
adversely affect the tax-qualified status of any such plan. No Weeks Benefit
Plan is or has ever been subject to Part III of Subtitle B of Title I of ERISA
or Title IV of ERISA or Section 412 of the Code. None of Weeks or any Weeks
Subsidiary, or any "party in interest" (as defined in Section 3(14) of ERISA) or
any "disqualified person" (as defined in Section 4975 of the Code) with respect
to any Weeks Benefit Plan, has engaged in a non-exempt "prohibited transaction"
within the meaning of Section 4975 of the Code or Section 406 of ERISA that
would have a Weeks Material Adverse Effect.

         (i) TAXES.

                  (i) Each of Weeks and each Weeks Subsidiary (including Weeks
OP) has timely filed all Tax Returns and reports required to be filed by it
(after giving effect to any filing extension properly granted by a Governmental
Entity having authority to do so). Each such Tax Return is true, correct and
complete in all material respects. Weeks and each Weeks Subsidiary (including
Weeks OP) have paid (or Weeks has paid on their behalf), within the time and
manner prescribed by law, all Taxes that are due and payable. The Tax Returns of
Weeks and each Weeks Subsidiary have not been audited by any Governmental Entity
responsible for tax matters (a "TAXING AUTHORITY"). There are no Tax liens upon
the assets of Weeks or any Weeks Subsidiary other than liens for Taxes not yet
due. The most recent financial statements contained in the Weeks SEC Documents
filed with the SEC prior to the date of this Agreement reflect an adequate
reserve for all material Taxes payable by Weeks and by each Weeks Subsidiary for
all taxable periods and portions thereof through the date of such financial
statements. Since the Weeks Financial Statement Date, Weeks has incurred no
liability for federal taxes, other than withholding and employment taxes, under
the Code or IRS Notice 88-19. To the knowledge of Weeks, no event has occurred,
and no condition or circumstance exists, which presents a material risk that any
material Tax described in the preceding sentence will be imposed upon Weeks. No
deficiencies for any Taxes have been proposed, asserted or assessed against
Weeks or any of the Weeks Subsidiaries, and no requests for waivers of the time
to assess any such Taxes have been granted or are pending. As used in this
Agreement, "TAXES" or "TAX" shall mean any federal, state, local or foreign
income, gross receipts, license, payroll, employment withholding, property,
recording, stamp, sales, excise or other tax or governmental charges of any
nature whatsoever, together with any penalties, interest or additions thereto
and "TAX RETURN" shall mean any return, declaration, report, claim for refund,
or information return or statement relating to Taxes, including any schedule or
attachment thereto, and including any amendment thereof.

                  (ii) Weeks (A) for each taxable year beginning with the
taxable year ending on December 31, 1994, has been subject to taxation as a REIT
within the meaning of the Code and has satisfied the requirements to qualify as
a REIT for such years, (B) has operated, and intends to continue to operate, in
such a manner as to qualify as a REIT through the end of its taxable year ending
at the Effective Time, and (C) has not taken or omitted to take any action which
could reasonably be expected to result in a challenge to its status as a REIT,
and no such challenge is pending or to Weeks' knowledge, threatened. Weeks OP
has at all times, and each other Weeks Subsidiary which is a partnership or
files Tax Returns as a partnership or limited liability company for federal
income tax purposes has since its acquisition by Weeks been classified for
federal income tax purposes as a partnership or disregarded entity and not as an
association taxable as a corporation, or a "publicly traded partnership" within
the meaning of Section 7704(b) of the Code that is treated as a corporation for
federal income tax purposes under Section 7704(a) of the Code. Neither Weeks nor
any Weeks Subsidiary holds any asset (x) the disposition of which would be
subject to rules similar to Section 1374 of the Code as announced in IRS Notice
88 19 or (y) that is subject to a consent filed pursuant to Section 341(f) of
the Code and the regulations thereunder.

                  (iii) As of the date hereof, Weeks does not have any earnings
and profits attributable to Weeks or any other corporation in any non-REIT year
within the meaning of Section 857 of the Code.

                  (iv) To the best knowledge of Weeks, Weeks qualifies as a
"domestically-controlled" REIT within the meaning of Section 897(h)(4)(B) of the
Code, as of the date hereof.

         (j) NO LOANS OR PAYMENTS TO EMPLOYEES, OFFICERS OR DIRECTORS. Except as
disclosed in the Weeks SEC Documents or as otherwise specifically provided for
in this Agreement, there is no (i) loan outstanding from or to any employee or
director, (ii) employment or consulting contracts, (iii) agreements requiring
payments to be made on a change of control or otherwise as a result of the
consummation of the REIT Merger, the OP Merger or any of the other transactions
contemplated by this Agreement or the OP Merger Agreement with respect to any
employee, officer or director of Weeks or any Weeks Subsidiary or (iv) any
agreement to appoint or nominate any person as a director of Weeks.

         (k) BROKERS; SCHEDULE OF FEES AND EXPENSES. No broker, investment
banker, financial advisor or other person, other than Goldman, Sachs & Co., the
fees and expenses of which, as set forth in a letter agreement between Weeks and
such financial advisor, have previously been disclosed to Duke and will be paid
by Weeks, is entitled to any broker's, finder's, financial advisor's or other
similar fee or commission in connection with the REIT Merger or the OP Merger or
any of the other transactions contemplated by this Agreement or the OP Merger
Agreement based upon arrangements made by or on behalf of Weeks or any Weeks
Subsidiary.

         (l) COMPLIANCE WITH LAWS. Except as disclosed in the Weeks SEC
Documents filed with the SEC prior to the date of this Agreement, neither Weeks
nor any of the Weeks Subsidiaries has violated or failed to comply with any
statute, law, ordinance, regulation, rule, judgment, decree or order of any
Governmental Entity applicable to its business, properties or operations, except
for violations and failures to comply that would not, individually or in the
aggregate, reasonably be expected to result in a Weeks Material Adverse Effect.

         (m) CONTRACTS; DEBT INSTRUMENTS.

         (i) Neither Weeks nor any Weeks Subsidiary has received written notice
that it is in violation of or in default under, in any material respect (nor
does there exist any condition which upon the passage of time or the giving of
notice or both would cause such a violation of or default under), any material
loan or credit agreement, note, bond, mortgage, indenture, lease, permit,
concession, franchise or



                                       13
<PAGE>

license, or any agreement to acquire real property, or any other material
contract, agreement, arrangement or understanding, to which it is a party or by
which it or any of its properties or assets is bound, except for violations or
defaults that would not, individually or in the aggregate, result in a Weeks
Material Adverse Effect.

                  (ii) Section 3.1(m)(ii) of the Weeks Disclosure Letter sets
forth (A) a detailed list of all indebtedness of Weeks or any of the Weeks
Subsidiaries, other than indebtedness payable to Weeks or a wholly owned Weeks
Subsidiary, in an aggregate principal amount in excess of $5,000,000 per item is
outstanding or may be incurred and (B) the respective principal amounts
outstanding thereunder on December 31, 1998. For purposes of this Section
3.1(m)(ii) and Section 3.2(m)(ii), "indebtedness" shall mean, with respect to
any person, without duplication, (A) all indebtedness of such person for
borrowed money, whether secured or unsecured, (B) all obligations of such person
under conditional sale or other title retention agreements relating to property
purchased by such person, (C) all capitalized lease obligations of such person,
(D) all obligations of such person under interest rate or currency hedging
transactions (valued at the termination value thereof), and (E) all guarantees
of such person of any such indebtedness of any other person.

                  (iii) Neither Weeks nor any Weeks Subsidiary has entered into
or is subject, directly or indirectly, to any Weeks Tax Protection Agreements.
As used herein, a "WEEKS TAX PROTECTION AGREEMENT" is an agreement, oral or
written, (A) that has as one of its purposes to permit a Person to take the
position that such Person could defer federal taxable income attributable to the
acquisition or ownership of Weeks OP Units or an interest in any other Weeks
Subsidiary that is treated as a partnership for federal income tax purposes, and
(B) that (i) prohibits or restricts in any manner the disposition of any assets
of Weeks or any Weeks Subsidiary, (ii) requires that Weeks or any Weeks
Subsidiary maintain, increase or put in place, or replace, indebtedness, whether
or not secured by one or more of the Weeks Properties, or (iii) requires that
Weeks or any Weeks Subsidiary offer to any person or entity at any time the
opportunity to guarantee or otherwise assume, directly or indirectly, the risk
of loss for federal income tax purposes for indebtedness or other liabilities of
Weeks or any Weeks Subsidiary.

         (n) OP AGREEMENT. The Agreement of Limited Partnership of Weeks OP, as
amended through the date hereof (the "WEEKS OP AGREEMENT") has been duly
authorized, executed and delivered by Weeks GP and Weeks LP. Assuming due
execution by the limited partners of Weeks OP, the Weeks OP Agreement
constitutes a valid and binding obligation of Weeks GP and Weeks LP, enforceable
against Weeks GP and Weeks LP in accordance with its terms.

         (o) ENVIRONMENTAL MATTERS. Except as disclosed in Section 3.1(o) of the
Weeks Disclosure Letter, each of Weeks and each Weeks Subsidiary has obtained
all licenses, permits, authorizations, approvals and consents from Governmental
Entities which are required of Weeks and each Weeks Subsidiary in respect of its
business, operations, assets or properties under any applicable Environmental
Law (as defined below) and each of Weeks and each Weeks Subsidiary is in
compliance in all respects with the terms and conditions of all such licenses,
permits, authorizations, approvals and consents and with its obligations under
any applicable Environmental Law, except for such failures to comply which would
not, individually or in the aggregate, have a Weeks Material Adverse Effect.
Except as disclosed in Section 3.1(o) of the Weeks Disclosure Letter or in the
environmental audits/reports listed thereon:

         (i) No Order has been issued that is still in effect, no complaint has
been filed that has not been resolved, no penalty has been assessed that has not
been paid and no investigation or review is pending or, to the Knowledge of
Weeks and its Subsidiaries, threatened by any Governmental Entity with respect
to any alleged failure by Weeks or any Weeks Subsidiary to have any license,
permit, authorization, approval or consent from Governmental Entities required
under any applicable Environmental Law in connection with the conduct of the
business or operations of Weeks or any Weeks



                                       14

or any Weeks Subsidiary of any Hazardous Material (as defined below).

                  (ii) Neither Weeks nor any Weeks Subsidiary nor, to the

Weeks Subsidiary owned or leased such property or, to the Knowledge of Weeks and
its Subsidiaries, prior thereto.

                  (iii) Neither Weeks nor any Weeks Subsidiary has transported
or arranged for the transportation of any Hazardous Material to any location
which is the subject of any action, suit, arbitration or proceeding that could
be reasonably expected to lead to claims against Weeks or any Weeks Subsidiary
related to such Hazardous Material for clean-up costs, remedial work, damages to
natural resources or personal injury claims, including, but not limited to,
claims under the Comprehensive Environmental Response, Compensation and
Liability Act of 1980, as amended, and the rules and regulations promulgated
thereunder ("CERCLA").

                  (iv) No oral or written notification of a Release of a
Hazardous Material has been filed or should have been filed by or on behalf of
Weeks or any Weeks Subsidiary under an applicable Environmental Law, except for
failures to make filings which would not, individually or in the aggregate, have
a Weeks Material Adverse Effect, and no property now or previously owned or
leased by Weeks or any Weeks Subsidiary is listed or, to the Knowledge of Weeks
and its Subsidiaries, proposed for listing on the National Priorities List
promulgated pursuant to CERCLA or on any similar state list of sites requiring
investigation or clean-up.

                  (v) There are no Liens arising under or pursuant to any
applicable Environmental Law on any real property owned or leased by Weeks or
any Weeks Subsidiary, and no action of any Governmental Entity has been taken
or, to the knowledge of Falcon and the Falcon Subsidiaries, is in process which
could subject any of such properties to such Liens, and neither Weeks nor any
Weeks Subsidiary currently has a duty under any applicable Environmental Law to
place any notice or restriction relating to the presence of Hazardous Material
at any such property owned by it in any deed to such property.

                  (vi) There have been no environmental investigations, studies,
audits, tests, reviews or other analyses conducted by or which are in the
possession or control of Weeks or any Weeks Subsidiary in relation to any

of the State of Georgia, including, without limitation, the fair price
provisions of Section 14-2-110 ET SEQ. of the GBCC and the business combination
provisions of Section 14-2-1131 ET SEQ. of the GBCC.

                  (ii) Weeks has taken all actions necessary to exclude Duke and
any Duke Subsidiary from the definition of "Acquiring Person" under the Rights
Agreement, dated as of May 20, 1998, between Weeks and Wachovia Bank, N.A. (the
"RIGHTS AGREEMENT").

         (t) INVESTMENT COMPANY ACT OF 1940. None of Weeks or any of the Weeks
Subsidiaries is, or at the Effective Time will be, required to be registered
under the Investment Company Act of 1940, as amended (the "1940 ACT").

         (u) PROXY STATEMENT AND REGISTRATION STATEMENT. The information
furnished by Weeks for inclusion or incorporation by reference in the
Registration Statement and any amendment or supplement thereto will not, as of
the date the Registration Statement is declared effective by the SEC contain any
untrue statement of a material fact or omit to state any material fact required
to be stated therein or necessary in order to make the statements therein not
misleading. The information furnished by Weeks for inclusion or incorporation by
reference in the Proxy Statement will not, on the date the Proxy Statement is
first mailed or furnished to securityholders of Weeks or Duke or on the
respective meeting dates, contain an untrue statement of a material fact or omit
to state a material fact required to be stated therein or necessary to make the
statements therein, in light of the circumstances in which they were 



                                       17

made, not misleading. Notwithstanding the foregoing, Weeks makes no
representation or warranty with respect to any information furnished by Duke for
inclusion or incorporation by reference in any of the foregoing documents.

         (v) VOTE REQUIRED. The affirmative vote of at least a majority of the
outstanding shares of Weeks Common Stock is the only vote of the holders of any
class or series of Weeks' capital stock necessary (under applicable law or
otherwise) to approve the REIT Merger, this Agreement, the OP Merger, the OP
Merger Agreement and the other transactions contemplated hereby and thereby (the
"WEEKS SHAREHOLDER APPROVALS"). The affirmative vote (by written consent or
otherwise) of holders of at least a majority of the outstanding Weeks common OP
Units (other than OP Units held by Weeks or any Weeks Subsidiary) is the only
vote of the holders of any interest in Weeks OP necessary (under applicable law
or otherwise) to approve the REIT Merger, this Agreement, the OP Merger, the OP
Merger Agreement and the other transactions contemplated hereby and thereby (the
"WEEKS OP APPROVALS"). The Weeks OP Approvals have been duly obtained.

         (w) YEAR 2000 ISSUES.

                  (i) To the best knowledge of Weeks, based on representations
and warranties made by third parties, the software, hardware and equipment of
Weeks owned, leased or licensed by it and used in the conduct of its business
(the "WEEKS INFORMATION TECHNOLOGY"), as well as the elevator systems in Weeks'
Office Properties, and the heating ventilation and air conditioning, fire and
safety and other automated building systems at the Weeks Properties (the "WEEKS
BUILDING SYSTEMS") are Year 2000 Ready.

                  (ii) Weeks has (A) developed and delivered to Duke a
comprehensive plan (the "WEEKS Y2K PLAN") for insuring that the software,
hardware, equipment and systems of Weeks and the Weeks Subsidiaries used in the
conduct of its business as conducted on the date hereof will be Year 2000 Ready
and (B) met the Weeks Y2K Plan milestones such that all software, hardware,
equipment and systems of Weeks and Weeks Subsidiaries will be Year 2000 Ready,
except to the extent that its failure would not have a Weeks Material Adverse
Effect.

                  (iii) "YEAR 2000 READY" means that the software, hardware,
equipment and systems of Weeks and the Weeks Subsidiaries with respect to the
operation of their respective businesses and their general business plans will:
(A) handle date information involving any and all dates before, during and/or
after January 1, 2000, including accepting input, providing output and
performing date calculations in whole or in part; (B) operate, accurately and
without interruption on and in respect of any and all dates before, during
and/or after January 1, 2000 and without any change in performance; and(C) store
and provide date input information without creating any ambiguity as to the
century.

         Section 3.2. REPRESENTATIONS AND WARRANTIES OF DUKE. Except as set
forth in the letter of even date herewith (with section references organized in
accordance with Section 9.9) signed by the President or Chief Executive Officer
and the Chief Financial Officer of Duke and delivered to Weeks prior to the
execution hereof (the "DUKE DISCLOSURE LETTER"), Duke represents and warrants to
Weeks as follows:

         (a) ORGANIZATION, STANDING AND CORPORATE POWER OF DUKE. Duke is a
corporation duly organized and validly existing under the laws of Indiana and
has the requisite corporate power and authority to carry on its business as now
being conducted. Duke is duly qualified or licensed to do business and is in
good standing in each jurisdiction in which the nature of its business or the
ownership, leasing of its properties or management of properties for others
makes such qualification or licensing necessary, other than in such
jurisdictions where the failure to be so qualified or licensed, individually or
in the aggregate, would not have a material adverse effect on the business,
properties, financial condition



                                       18
<PAGE>

or results of operations of Duke and the Duke Subsidiaries, taken as a whole (a
"DUKE MATERIAL ADVERSE EFFECT").

                  (b) DUKE SUBSIDIARIES; INTERESTS IN OTHER PERSONS.

                  (i) Section 3.2(b) of the Duke Disclosure Letter sets forth
each Duke Subsidiary and the ownership interest therein of Duke and each other
Duke Subsidiary. All the outstanding shares of capital stock of each Duke
Subsidiary that is a corporation have been validly issued and are fully paid and
nonassessable and are not subject to any preemptive rights, and are owned by
Duke, by another Duke Subsidiary or by Duke and another Duke Subsidiary, free
and clear of all Liens, and all equity interests in each Duke Subsidiary,
including Duke OP, that is a partnership (other than Duke OP) or limited
liability company or trust are owned by Duke or by Duke and another Duke
Subsidiary free and clear of all Liens. Each Duke Subsidiary that is a
corporation is duly incorporated and validly existing under the laws of its
jurisdiction of incorporation and has the requisite corporate power and
authority to carry on its business as now being conducted and each Duke
Subsidiary, including Duke OP, that is a partnership, limited liability company
or trust is duly organized and validly existing under the laws of its
jurisdiction of organization and has the requisite power and authority to carry
on its business as now being conducted. Each Duke Subsidiary, including Duke OP,
is duly qualified or licensed to do business and is in good standing in each
jurisdiction in which the nature of its business or the ownership or leasing of
its properties makes such qualification or licensing necessary, other than in
such jurisdictions where the failure to be so qualified or licensed individually
or in the aggregate, would not have an Duke Material Adverse Effect.

                  (ii) Except for the capital stock of or other equity interests
in the Duke Subsidiaries and the other interests disclosed in Section 3.2(b)(ii)
of the Duke Disclosure Letter (the "DUKE OTHER INTERESTS"), Duke does not own,
directly or indirectly (including through any Duke Subsidiary), any capital
stock or other ownership interest, with a fair market value as of the date of
this Agreement greater than $250,000 in any Person or which represents 5% or
more of the voting power, outstanding capital stock or other ownership interest
of any class in any Person. Neither Duke nor any Duke Subsidiary is in material
default of any provision of any organizational documents governing or otherwise
relating to its rights in any Duke Other Interest. All such organizational
documents are set forth in Section 3.2(b)(ii) of the Duke Disclosure Letter and
are in full force and effect.

         (c) CAPITAL STRUCTURE. The authorized capital stock of Duke consists of
150,000,000 shares of Duke Common Stock and 5,000,000 shares of preferred stock,
par value $.01 per share (the "DUKE PREFERRED STOCK"). On the date hereof, (i)
86,352,441 shares of Duke Common Stock, 300,000 shares of Duke Series A
Preferred Stock, 300,000 shares of Duke Series B Preferred Stock, no shares of
Duke Series C Preferred Stock, 540,000 shares of Duke Series D Preferred Stock,
400,000 shares of Duke Series E Preferred Stock and 15,400,000 depositary
shares, each representing a 1/10 interest in a share of Duke Preferred Stock,
were issued and outstanding, (ii) an aggregate of 2,647,863 shares were
available for grant under Duke's 1993 Stock Option Plan, Duke's 1995 Key
Employees' Stock Option Plan, the 1996 Directors' Stock Payment Plan of Duke,
the Duke 401(k) Plan, the Duke Employee Stock Purchase Plan, the 1999 Directors'
Stock Option and Dividend Increase Unit Plan of Duke and the 1999 Salary
Replacement Stock Option and Dividend Increase Unit Plan of Duke, (iii) a total
of 199,642 units of limited partnership interest were available for grant under
the 1995 Dividend Increase Unit Plan of Duke Realty Services Limited
Partnership, the 1995 Shareholder Value Plan of Duke Realty Services Limited
Partnership and the Executives Deferred Compensation Plan of Duke Realty
Services Limited Partnership (the plans named in clauses (i) and (ii) being the
"DUKE STOCK PLANS"), 2,857,742 shares of Duke Common Stock and 34,356 units of
limited partnership interest in Duke Realty Services Limited Partnership were
reserved for issuance upon exercise of outstanding options to purchase shares of
Duke Common Stock and units of limited partnership interest in Duke Realty

                                       19
<PAGE>

employees of Duke and Duke Subsidiaries and directors of Duke under the Duke
Stock Plans (the "DUKE STOCK OPTIONS"), and (iv) 10,831,552 shares of Duke
Common Stock were reserved for issuance upon exchange of units of limited
partnership interests in Duke OP ("DUKE OP UNITS") for shares of Duke Common
Stock pursuant to the Duke OP Agreement and the other agreements listed in
Section 3.2(c) of the Duke Disclosure Letter (the "DUKE EXCHANGE AGREEMENTS").
On the date of this Agreement, except as set forth in this Section 3.2(c), no
shares of capital stock or other voting securities of Duke were issued, reserved
for issuance or outstanding. There are no outstanding stock appreciation rights
relating to the capital stock of Duke. All outstanding shares of capital stock
of Duke are, and all shares which may be issued pursuant to this Agreement will
be, when issued, duly authorized, validly issued, fully paid and nonassessable
and not subject to preemptive rights. There are no bonds, debentures, notes or
other indebtedness of Duke having the right to vote (or convertible into, or
exchangeable for, securities having the right to vote) on any matters on which
shareholders of Duke may vote. Duke is the sole general partner of Duke OP and
also holds an 88.9% limited partner interest in Duke OP. As of the date hereof,
97,183,993 common Duke OP Units, 300,000 Series A Preferred Duke OP Units,
300,000 Series B Duke OP Units, no Series C Preferred Duke OP Units and 540,000
Series D Preferred Duke OP Units are validly issued and outstanding, fully paid
and nonassessable and not subject to preemptive rights. The common Duke OP Units
not held by Duke are exchangeable for Duke Common Stock on a one-for-one basis
into an aggregate of 10,831,552 shares of Duke Common Stock in accordance with
the terms of the Duke OP Agreement and the Duke Exchange Agreements, subject to
adjustment as provided in the Duke OP Agreement and the Duke Exchange
Agreements. Section 3.2(c) of the Duke Disclosure Letter sets forth the name,
number and class of OP Units and the percentage interest of each partner in Duke
OP. Except as set forth in this Section 3.2(c), and except (A) for the Duke
Stock Options and Duke OP Units (which, subject to certain restrictions, may be
delivered to Duke in exchange for Duke Common Stock), and (B) as contemplated
under Duke's dividend reinvestment plan and employee stock purchase plan, as of
the date of this Agreement there are no outstanding securities, options,
warrants, calls, rights, commitments, agreements, arrangements or undertakings
of any kind to which Duke or any Duke Subsidiary, including Duke OP, is a party
or by which such entity is bound, obligating Duke or any Duke Subsidiary,
including Duke OP, to issue, deliver or sell, or cause to be issued, delivered
or sold, additional shares of capital stock, voting securities or other
ownership interests of Duke or of any Duke Subsidiary, including Duke OP, or
obligating Duke or any Duke Subsidiary, including Duke OP, to issue, grant,
extend or enter into any such security, option, warrant, call, right,
commitment, agreement, arrangement or undertaking (other than to Duke or a Duke
Subsidiary). Except as set forth in this Section 3.2(c), there are no
outstanding contractual obligations of Duke or any Duke Subsidiary, including
Duke OP, to repurchase, redeem or otherwise acquire any shares of capital stock
or other ownership interests in Duke or any Duke Subsidiary, including Duke OP,
or make any material investment (in the form of a loan, capital contribution or
otherwise) in any Person other than Duke OP.

                  (d) AUTHORITY; NONCONTRAVENTION; CONSENTS. Duke has the
requisite corporate power and authority to enter into this Agreement and,
subject to receipt of the Duke Shareholder Approvals (as defined in Section
3.2(u)), to consummate the transactions contemplated by this Agreement. Duke, on
behalf of Duke OP, as its sole general partner, has the requisite power and
authority to enter into the OP Merger Agreement and to consummate the
transactions contemplated by the OP Merger Agreement. The execution and delivery
of this Agreement and other agreements contemplated by this Agreement by Duke
and the consummation by Duke of the transactions contemplated hereby to which
Duke is a party have been duly authorized by all necessary action on the part of
Duke, subject to receipt of the Duke Shareholder Approvals. The execution and
delivery of the OP Merger Agreement and any other agreement contemplated by this
Agreement or the OP Merger Agreement by Duke, as the sole general partner of
Duke OP, and by Duke OP and the consummation by Duke OP of the transactions
contemplated hereby and by the OP Merger Agreement have been duly authorized by
all necessary partnership action. This Agreement, the OP Merger Agreement and
the other agreements contemplated by this Agreement have been duly executed and
delivered by Duke or Duke OP, as the case may be, and



                                       20
<PAGE>

constitute the valid and binding obligations of Duke and Duke OP, as the case
may be, enforceable against Duke or Duke OP in accordance with their terms. The
execution and delivery of this Agreement, the OP Merger Agreement and the other
agreements contemplated by this Agreement and the OP Merger Agreement by Duke on
behalf of itself and as general partner of Duke OP do not, and the consummation
of the transactions contemplated hereby and thereby to which either Duke or Duke
OP is a party and compliance by either Duke or Duke OP with the provisions of
this Agreement, the OP Merger Agreement and the other agreements contemplated by
this Agreement and the OP Merger Agreement will not, conflict with, or result in
any violation of, or default (with or without notice or lapse of time, or both)
under, or give rise to a right of termination, cancellation or acceleration of
any obligation or to loss of a material benefit under, or result in the creation
of any Lien upon any of the properties or assets of Duke or any Duke Subsidiary
under, (i) the Charter or By-laws or the comparable charter or organizational
documents or partnership or similar agreement (as the case may be) of any Duke
Subsidiary, each as amended or supplemented to the date of this Agreement, (ii)
any loan or credit agreement, note, bond, mortgage, indenture, reciprocal
easement agreement, lease or other agreement, instrument, permit, concession,
contract, franchise or license applicable to Duke or any Duke Subsidiary or
their respective properties or assets or (iii) subject to the governmental
filings and other matters referred to in the following sentence, any Laws
applicable to Duke or any Duke Subsidiary or their respective properties or
assets, other than, in the case of clause (ii) or (iii), any such conflicts,
violations, defaults, rights or Liens that individually or in the aggregate
would not (x) have a Duke Material Adverse Effect or (y) materially delay or
prevent the consummation of the REIT Merger or the OP Merger or the transactions
contemplated by this Agreement or the OP Merger Agreement. No consent, approval,
order or authorization of, or registration, declaration or filing with, any
Governmental Entity is required by or with respect to Duke or any Duke
Subsidiary (including Duke OP) in connection with the execution and delivery of
this Agreement, the OP Merger Agreement or the other agreements contemplated by
this Agreement, by Duke or Duke OP, as the case may be, or the consummation by
Duke and its Subsidiaries of any of the transactions contemplated hereby, except
for (i) the filing with the SEC of (x) the Proxy Statements and the Registration
Statements and (y) such reports under Section 13 of the Exchange Act as may be
required in connection with this Agreement and the transactions contemplated by
this Agreement, (ii) the filing of the Articles of Merger for the REIT Merger
with the Secretary of State of Indiana and the Secretary of State of Georgia,
(iii) the filing of a certificate of merger for the OP Merger with the Secretary
of State of Indiana and the Secretary of State of Georgia, (iv) such filings as
may be required in connection with the payment of any Transfer and Gains Taxes,
(v) the termination or expiration of all waiting periods under the HSR Act and
(vi) such other consents, approvals, orders, authorizations, registrations,
declarations and filings as are set forth in Section 3.2(d) of the Duke
Disclosure Letter or (A) as may be required under (x) federal, state or local
environmental laws or (y) the "blue sky" laws of various states or (B) which, if
not obtained or made, would not prevent or delay in any material respect the
consummation of the REIT Merger or the OP Merger or any of the transactions
contemplated by this Agreement or the OP Merger Agreement or otherwise prevent
Duke or Duke OP from performing its obligations under this Agreement in any
material respect or have, individually or in the aggregate, a Duke Material
Adverse Effect.

         (e) SEC DOCUMENTS; FINANCIAL STATEMENTS; UNDISCLOSED LIABILITIES. Duke
and Duke OP have filed all required reports, schedules, forms, statements and
other documents with the SEC since January 1, 1995 and August 4, 1997,
respectively (collectively, the "DUKE SEC DOCUMENTS"). All of the Duke SEC
Documents (other than preliminary materials or materials that were subsequently
amended), as of their respective filing dates, complied in all material respects
with all applicable requirements of the Securities Act and the Exchange Act and,
in each case, the rules and regulations promulgated thereunder applicable to
such Duke SEC Documents. None of the Duke SEC Documents at the time of filing
contained any untrue statement of a material fact or omitted to state any
material fact required to be stated therein or necessary in order to make the
statements therein, in light of the circumstances under which they were made,
not misleading, except to the extent such statements have been amended, modified
or superseded 



                                       21
<PAGE>

by later filed Duke SEC Documents. None of the Duke SEC Documents is the subject
of any confidential treatment request by Duke or Duke OP. Section 3.2(e) lists
all of the Duke SEC Documents filed with the SEC since January 1, 1998. The
consolidated financial statements of Duke and Duke OP, as applicable, included
in the Duke SEC Documents complied as to form in all material respects with
applicable accounting requirements and the published rules and regulations of
the SEC with respect thereto, have been prepared in accordance with GAAP
(except, in the case of interim financial statements, as permitted by the
applicable rules and regulations of the SEC) applied on a consistent basis
during the periods involved (except as may be indicated in the notes thereto)
and fairly presented in all material respects, in accordance with the applicable
requirements of GAAP, the consolidated financial position of Duke and the Duke
Subsidiaries, taken as a whole, as of the dates thereof and the consolidated
results of operations and cash flows for the periods then ended (subject, in the
case of interim financial statements, to normal year-end adjustments). Except as
set forth in the Duke SEC Documents filed with the SEC prior to the date of this
Agreement, neither Duke nor any Duke Subsidiary has any liabilities or
obligations of any nature (whether accrued, absolute, contingent or otherwise)
required by GAAP to be set forth on a consolidated balance sheet of Duke or in
the notes thereto and which, individually or in the aggregate, would have a Duke
Material Adverse Effect.

         (f) ABSENCE OF CERTAIN CHANGES OR EVENTS. Except as disclosed in the
Duke SEC Documents filed with the SEC prior to the date of this Agreement since
December 31, 1997 (the "DUKE FINANCIAL STATEMENT DATE") and to the date of this
Agreement, Duke and the Duke Subsidiaries have conducted their business only in
the ordinary course and there has not been (i) any change that would have a Duke
Material Adverse Effect (a "DUKE MATERIAL ADVERSE Change"), nor has there been
any occurrence or circumstance that with the passage of time would reasonably be
expected to result in an Duke Material Adverse Change, (ii) any declaration,
setting aside or payment of any dividend or distribution (whether in cash, stock
or property) with respect to any of Duke's capital stock or any Duke OP Units,
except for (A) regular quarterly dividends (in the case of Duke) of $.34 per
share of Duke Common Stock, and the dividend, if any, to be paid by Duke
pursuant to Section 2.2(c)(i) (and the corresponding Duke OP distribution), (B)
regular quarterly distributions (in the case of Duke OP) of $.34 per Duke Common
OP Unit, $.56875 per Duke Series A Preferred OP Unit, $.99875 per Duke Series B
Preferred OP Unit, $.46 per Duke Series D Preferred Unit and $.515625 per Duke
Series E Preferred Unit, (C) regularly quarterly dividends (in the case of Duke)
of $.56875 on outstanding shares of Duke Series A Preferred Stock, $.99875 on
Duke Series B Preferred Stock, $.46 on Duke Series D Preferred Stock and
$.515625 on Duke Series E Preferred Stock and (D) any distributions by any Duke
Subsidiaries (other than Duke OP) to other Duke Subsidiaries or to Duke, in each
case with customary record and payment dates, (iii) any split, combination or
reclassification of any of Duke's capital stock or any issuance or the
authorization of any issuance of any other securities in respect of, in lieu of
or in substitution for, or giving the right to acquire by exchange or exercise,
shares of its capital stock or any issuance of an ownership interest in any Duke
Subsidiary, (iv) any damage, destruction or loss, whether or not covered by
insurance, that has or would have a Duke Material Adverse Effect, or (v) any
change in accounting methods, principles or practices by Duke or any Duke
Subsidiary materially affecting its assets, liabilities or business, except
insofar as may have been disclosed in the Duke SEC Documents filed with the SEC
prior to the date of this Agreement, or required by a change in GAAP.

         (g) LITIGATION. Except as disclosed in the Duke SEC Documents filed
with the SEC prior to the date of this Agreement and other than personal injury
and other routine tort litigation arising from the ordinary course of operations
of Duke or the Duke Subsidiaries which are covered by adequate insurance, there
is no suit, action or proceeding pending or, to the knowledge of Duke and Duke
OP, threatened against or affecting Duke or any Duke Subsidiary that,
individually or in the aggregate, could reasonably be expected to (i) have a
Duke Material Adverse Effect or (ii) prevent the consummation of any of the
transactions contemplated hereby, nor is there any judgment, decree, injunction,
rule or order of any



                                       22
<PAGE>

Governmental Entity or arbitrator outstanding against Duke or any Duke
Subsidiary having, or which, insofar as reasonably can be foreseen, in the
future would have, any such effect.

         (h) ABSENCE OF CHANGES IN BENEFIT PLANS; ERISA COMPLIANCE.

                  (i) Except as disclosed in the Duke SEC Documents filed with
the SEC prior to the date of this Agreement, since the Duke Financial Statement
Date, there has not been any adoption or amendment in any material respect, or
the undertaking of any additional obligation, by Duke, any Duke Subsidiary or
any Duke ERISA Affiliate (as defined below) of any Duke Benefit Plan (as defined
below). For purposes of this Agreement, "DUKE BENEFIT PLAN" shall mean any
Employee Plan sponsored or maintained by Duke, any Duke Subsidiary or any Duke
ERISA Affiliate, or with respect to which Duke, any Duke Subsidiary or any Duke
ERISA Affiliate has any obligation to contribute, has liability under or is
otherwise a party to, or which otherwise provides benefits for any current or
former employees, officers, directors or other independent contractors (or their
dependents and beneficiaries) of Duke or any Duke Subsidiary. For purposes of
this Agreement, "DUKE ERISA AFFILIATE" means any entity required to be
aggregated with any of Duke or any Duke Subsidiary under Sections 414(b), (c),
(m) or (o) of the Code or Section 4001 of ERISA. Schedule 3.2(h)(i) to the Duke
Disclosure Letter sets forth each Duke Benefit Plan.

                  (ii) Except as described in the Duke SEC Documents filed with
the SEC prior to the date of this Agreement or as would not have a Duke Material
Adverse Effect, (A) all Duke Benefit Plans, including any such plan that is an
"employee benefit plan" as defined in Section 3(3) of ERISA, are in compliance
with the terms of such plan and all applicable requirements of law, including
ERISA and the Code and, without limitation, the requirements of ERISA and all
tax rules for which favorable tax treatment is intended, and (B) there are no
liabilities or obligations with respect to any such Duke Benefit Plan, whether
accrued, contingent or otherwise (other than obligations by Duke and the Duke
Subsidiaries to make contributions, and for such plan to pay benefits and
administrative costs, incurred in the ordinary course), nor to the knowledge of
Duke are any such liabilities or obligations expected to be incurred. The
execution of, and performance of the transactions contemplated in, this
Agreement will not (either alone or together with the occurrence of any
additional or subsequent events) constitute an event under any Duke Benefit
Plan, policy, program, arrangement or agreement, trust or loan that will or may
result in any payment (whether of severance pay or otherwise), acceleration,
forgiveness of indebtedness, vesting, distribution, increase in benefits or
obligation to fund benefits with respect to any employee or director, will not
result in any "golden parachute payments" being due (as defined for purposes of
Section 280G of the Code), or result in any breach or violation of, or a default
under, any of the Duke Benefit Plans. The only severance agreements or severance
policies applicable to Duke or the Duke Subsidiaries are the agreements and
policies specifically referred to in Section 3.2(h)(ii) of the Duke Disclosure
Letter.

                  (iii) Without limiting the foregoing, each Duke Benefit Plan
which is intended to be tax-qualified under Section 401(a) of the Code has been
determined by the IRS to be so qualified and such determination has not been
modified, revoked or limited, and no circumstances have occurred that would
adversely affect the tax-qualified status of any such plan. No Duke Benefit Plan
is or has ever been subject to Part III of Subtitle B of Title I of ERISA or
Title IV of ERISA or Section 412 of the Code. None of Duke or any Duke
Subsidiary, or any "party in interest" (as defined in Section 3(14) of ERISA) or
any "disqualified person" (as defined in Section 4975 of the Code) with respect
to any Duke Benefit Plan, has engaged in a non-exempt "prohibited transaction"
within the meaning of Section 4975 of the Code or Section 406 of ERISA that
would have a Duke Material Adverse Effect.

                                       23

(i)      TAXES.

         (i) Each of Duke and each Duke Subsidiary (including Duke OP) has
timely filed with the appropriate taxing authority all Tax Returns and reports
required to be filed by it (after giving effect to any filing extension properly
granted by a Governmental Entity having authority to do so). Each such Tax
Return is true, correct and complete in all material respects. Duke and each
Duke Subsidiary (including Duke OP) have paid (or Duke has paid on their
behalf), within the time and manner prescribed by law, all Taxes that are due
and payable. The Tax Returns of Duke and each Duke Subsidiary have not been
audited by any Taxing Authority. There are no Tax liens upon the assets of Duke
or any Duke Subsidiary other than liens for Taxes not yet due. The most recent
financial statements contained in the Duke SEC Documents filed with the SEC
prior to the date of this Agreement reflect an adequate reserve for all material
Taxes payable by Duke and by each Duke Subsidiary for all taxable periods and
portions thereof through the date of such financial statements. Since the Duke
Financial Statement Date, Duke has incurred no liability for federal taxes,
other than withholding and employment taxes, under the Code or IRS Notice 88-19.
To the knowledge of Duke, no event has occurred, and no condition or
circumstance exists, which presents a material risk that any material Tax
described in the preceding sentence will be imposed upon Duke. To the knowledge
of Duke, no deficiencies for any Taxes have been proposed, asserted or assessed
against Duke or any of the Duke Subsidiaries, and no requests for waivers of the
time to assess any such Taxes have been granted or are pending.

         (ii) Duke (A) for all of its taxable years beginning with its taxable
year ending on December 31, 1986 has been subject to taxation as a REIT within
the meaning of the Code and has satisfied the requirements to qualify as a REIT
for such years, (B) has operated, and intends to continue to operate, in such a
manner as to qualify as a REIT, and (C) has not taken or omitted to take any
action which could reasonably be expected to result in a challenge to its status
as a REIT, and, to Duke's knowledge, no such challenge is pending or threatened.
Duke OP has at all times, and each other Duke Subsidiary which is a partnership
or limited liability company or files Tax Returns as a partnership for federal
income tax purposes has since its acquisition by Duke, been classified for
federal income tax purposes as a partnership or disregarded entity and not as an
association taxable as a corporation or a "publicly traded partnership" within
the meaning of Section 7704(b) of the Code that is treated as a corporation for
federal income tax purposes under Section 7704(a) of the Code. Duke OP has
operated, and Duke intends to cause Duke OP to continue to operate, in such a
manner as to satisfy the gross income requirements of Section 7704(c)(2) of the
Code, so that if Duke OP were classified as a publicly traded partnership, Duke
OP would not be treated for federal income tax purposes as a corporation under
Section 7704(a) of the Code.

         (iii) To the best knowledge and belief of Duke, Duke qualifies as a
"domestically-controlled" REIT within the meaning of Section 897(h)(4)(B) of the
Code, as of the date hereof.

    (j) NO LOANS OR PAYMENTS TO EMPLOYEES, OFFICERS OR DIRECTORS. Except as
disclosed in the Duke SEC Documents or as otherwise specifically provided for in
this Agreement, there is no (i) loan outstanding from or to any employee or
director, (ii) employment or consulting contracts, (iii) agreements requiring
payments to be made on a change of control or otherwise as a result of the
consummation of any of the transactions with respect to any employee, officer or
director of Duke or any Duke Subsidiary or (iv) any agreement to appoint or
nominate any person as a director of Duke.

     (k) BROKERS; SCHEDULE OF FEES AND EXPENSES. No broker, investment banker,
financial advisor or other person, other than Merrill Lynch & Co., the fees and
expenses of which, as set forth in a letter agreement between Duke and such
financial advisor, have previously been disclosed to Weeks and will be paid by
Duke, is entitled to any broker's, finder's, financial advisor's or other
similar fee or commission in connection with the REIT Merger, the OP Merger or
any of the transactions contemplated 



                                       24

by this Agreement or the OP Merger Agreement based upon arrangements made by or
on behalf of Duke or any other Duke Subsidiary.

     (l) COMPLIANCE WITH LAWS. Except as disclosed in the Duke SEC Documents
filed with the SEC prior to the date of this Agreement neither Duke nor any of
the Duke Subsidiaries has violated or failed to comply with any statute, law,
ordinance, regulation, rule, judgment, decree or order of any Governmental
Entity applicable to its business, properties or operations, except for
violations and failures to comply that would not, individually or in the
aggregate, reasonably be expected to result in a Duke Material Adverse Effect.

     (m) CONTRACTS; DEBT INSTRUMENTS.

         (i) Neither Duke nor any Duke Subsidiary has received written notice
that it is in violation of or in default under, in any material respect (nor

notice or both would cause such a violation of or default under), any material
loan or credit agreement, note, bond, mortgage, indenture, lease, permit,
concession, franchise or license, or any agreement to acquire real property, or
any other material contract, agreement, arrangement or understanding, to which
it is a party or by which it or any of its properties or assets is bound, except

detailed list of all loan indebtedness of Duke or any of the Duke Subsidiaries,
other than indebtedness payable to Duke or a wholly owned Duke Subsidiary, in an
aggregate principal amount in excess of $5,000,000 per item is outstanding or
may be incurred and (B) the respective principal amounts outstanding thereunder
on December 31, 1998.

         (iii) Neither Duke nor any Duke Subsidiary has entered into or is
subject, directly or indirectly, to any Duke Tax Protection Agreements. As used
herein, a "Duke Tax Protection Agreement" is an agreement, oral or written, (A)
that has as one of its purposes to permit a Person to take the position that
such Person could defer federal taxable income that otherwise might have been
recognized attributable to the acquisition or ownership of Duke OP Units or an
interest in any other Duke Subsidiary that is treated as a partnership for
federal income tax purposes, and (B) that (i) prohibits or restricts in any
manner the disposition of any assets of Duke or any Duke Subsidiary, (ii)
requires that Duke or any Duke Subsidiary maintain, increase or put in place, or
replace, indebtedness, whether or not secured by one or more of the Duke
Properties, or (iii) requires that Duke or any Duke Subsidiary offer to any
person or entity at any time the opportunity to guarantee or otherwise assume,
directly or indirectly, the risk of loss for federal income tax purposes for
indebtedness or other liabilities of Colt or any Colt Subsidiary.

     (n) DUKE OP AGREEMENT. The Duke OP Agreement has been duly authorized,

of Duke OP, the Duke OP Agreement constitutes a valid and binding obligation of
Duke, enforceable against Duke in accordance with its terms.

business, operations, assets or properties under any applicable Environmental
Law, and each of Duke and each Duke Subsidiary is in compliance in all respects
with the terms and conditions of all such licenses, permits, authorizations,
approvals and consents and with its obligations under any applicable
Environmental Law, except for such failures to comply which would not,

operations of Duke or any Duke Subsidiary or with respect to any Release by Duke
or any Duke Subsidiary of any Hazardous Material.

Duke Subsidiary, during any period that Duke or any Duke Subsidiary owned or
leased such property or, to the Knowledge of Duke and its Subsidiaries, prior
thereto.

         (iii) Neither Duke nor any Duke Subsidiary has transported or arranged
for the transportation of any Hazardous Material to any location which is the
subject of any action, suit, arbitration or proceeding that could be reasonably
expected to lead to claims against Duke or any Duke Subsidiary related to such
Hazardous Material for clean-up costs, remedial work, damages to natural
resources or personal injury claims, including, but not limited to, claims under
CERCLA.

         (iv) No oral or written notification of a Release of a Hazardous
Material has been filed or should have been filed by or on behalf of Duke or any
Duke Subsidiary under an applicable Environmental Law, except for failures to
make filings which would not, individually or in the aggregate, have a Material
Adverse Effect and no property now or previously owned or leased by Duke or any
Duke Subsidiary is listed or, to the Knowledge of Duke and its Subsidiaries,
proposed for listing on the National Priorities List promulgated pursuant to

been listed in Section 3.2(o)(vi) of the Duke Disclosure Letter and made
available to Weeks prior to the execution of this Agreement.

STATEMENT; SHAREHOLDERS' MEETINGS; PARTNERS' CONSENTS.

     (a) As soon as practicable following the date of this Agreement, Weeks and
Duke shall (i) prepare and file with the SEC a preliminary joint Proxy
Statement, with appropriate requests for confidential treatment, in form and
substance satisfactory to each of Duke and Weeks, and Duke will provide on a
supplemental basis to the SEC the Registration Statement, in which the Proxy
Statement will be included as a prospectus. Each of Weeks and Duke shall use its
commercially reasonable efforts to cause and enable Duke to (i) respond to any
comments of the staff of the SEC and (ii) have the Registration Statement
declared effective under the Securities Act and the rules and regulations
promulgated thereunder as promptly as practicable after such filing and to keep
the Registration Statement effective as long as is necessary to consummate the
REIT Merger. Each of Weeks and Duke will use its commercially reasonable efforts
to cause the Proxy Statement to be mailed to Weeks' shareholders and Duke's
shareholders, respectively, as promptly as practicable after the Registration
Statement is declared effective under the Securities Act. Each party will notify
the other promptly of the receipt of any comments from the SEC and of any
request by the SEC for amendments or supplements to the Registration Statement
or the Proxy Statement or for additional information and will supply the other
with copies of all correspondence between such party or any of its
representatives and the SEC with respect to the Registration Statement or the
Proxy Statement. The Registration Statement and the Proxy Statement shall comply
in all material respects with all applicable requirements of Law. Whenever any
event occurs which is required to be set forth in an amendment or supplement to
the Registration Statement or the Proxy Statement, Duke or Weeks, as the case
may be, shall promptly inform the other of such occurrences and cooperate in
filing with the SEC and/or mailing to the shareholders of Duke and the
shareholders of Weeks such amendment or supplement in a form reasonably
acceptable to Duke and Weeks.

     (b) Weeks will, as soon as practicable following the date of this
Agreement, duly call, give notice of, convene and hold a meeting of its
shareholders (the "WEEKS SHAREHOLDERS MEETING") (but in no event shall such

Shareholder Approvals. Duke will, as soon as practicable following the date of
this Agreement, duly call, give notice of, convene and hold a meeting of its

meeting be held sooner than 20 business days following the date the Proxy
Statement is mailed to its shareholders), for the purpose of obtaining the Duke
Shareholder Approvals. Weeks and Duke will cooperate in good faith to seek to
ensure that the Weeks Shareholder Meeting and the Duke Shareholder Meeting are
held on the same day, as close together in time as is reasonably practicable.
Duke covenants that, subject to Section 7.1, Duke will, through its Board of
Directors, recommend to its shareholders approval of the REIT Merger, the OP
Merger, this Agreement, the OP Merger Agreement, the charter and bylaw
amendments, the election of directors and the other transactions contemplated
hereby and thereby and further covenants that the Proxy Statement will include
such recommendation. Weeks covenants that, subject to Section 7.1, Weeks will,

information concerning Duke and the holders of Duke Common Stock as may
reasonably be requested in connection with any action required to be taken under
any applicable state securities or "blue sky" laws in connection with the
issuance of Duke Common Stock pursuant to the REIT Merger, and Weeks shall
furnish all information concerning Weeks and the holders

action. Each of Duke and Weeks will use their commercially reasonable efforts to
cause Duke to obtain, prior to the effective date of the Registration Statement,
all necessary state securities or "blue sky" permits or approvals required to
carry out the REIT Merger and the other transactions contemplated by this
Agreement. In connection with the preparation of the Proxy Statement and the
Registration Statement, Duke shall use reasonable efforts to cause to be
delivered to Weeks, prior to the mailing of the Proxy Statement to Weeks'
shareholders and Duke's shareholders, the opinion dated the date of the Proxy
Statement of Rogers & Wells LLP, substantially in the form attached hereto as
EXHIBIT L (subject to customary exceptions, assumptions and qualifications, and
based on customary representations), regarding the qualification of Duke as a
REIT under the Code and the treatment of Duke OP as a partnership for federal
income tax purposes. In issuing its opinion, Rogers & Wells LLP shall be
permitted to rely on the opinion of King & Spalding as to the qualification of
Weeks as a REIT. In connection with the preparation of the Proxy Statement and
the Registration Statement, Weeks shall use reasonable efforts to cause to be
delivered to Duke, prior to the mailing of the Proxy Statement to Weeks'
shareholders and Duke's shareholders, the opinion dated the date of the Proxy
Statement of King & Spalding, substantially in the form attached hereto as
Exhibit K (subject to customary exceptions, assumptions and qualifications, and
based on customary representations), regarding the qualification of Weeks as a
REIT under the Code and the treatment of Weeks OP as a partnership for federal
income tax purposes.

     Section 5.2. ACCESS TO INFORMATION; CONFIDENTIALITY. Each of Weeks and Duke
shall, and shall cause each of its respective Subsidiaries to, afford to the
other party and to the officers, employees, accountants, counsel, financial
advisors and other representatives of such other party, reasonable access during
normal business hours during the period prior to the Effective Time to all their
respective properties, books, contracts, commitments, personnel and records and,
during such period, each of Weeks and Duke shall, and shall cause each of its
respective subsidiaries to, furnish promptly to the other party (a) a copy of
each report, schedule, registration statement and other document filed by it
during such period pursuant to the requirements of federal or state securities
laws and (b) all other information concerning its business, properties and
personnel as such other party may reasonably request. Each of Weeks and Duke
will hold, and will cause its respective subsidiaries' officers, employees,
accountants, counsel, financial advisors and other representatives and
affiliates to hold, any nonpublic information in confidence to the extent
required by, and in accordance with, and will comply with the provisions of the
letter agreement between Weeks and Duke dated as of February 3, 1999, as amended
to date (as so amended, the "CONFIDENTIALITY AGREEMENT").

     Section 5.3.  COMMERCIALLY REASONABLE EFFORTS; NOTIFICATION.

     (a) Upon the terms and subject to the conditions set forth in this
Agreement, each of Duke and Weeks agrees to use its commercially reasonable
efforts to take, or cause to be taken, all actions, and to do, or cause to be
done, and to assist and cooperate with the other in doing, all things necessary,
proper or advisable to fulfill all conditions applicable to such party pursuant
to this Agreement and to consummate and make effective, in the most expeditious
manner practicable, the REIT Merger, the OP Merger and the other transactions
contemplated hereby and by the OP Merger Agreement, including (i) the obtaining
of all necessary actions or nonactions, waivers, consents and approvals from
Governmental Entities and the making of all necessary registrations and filings
and the taking of all reasonable steps as may be necessary to obtain an
approval, waiver or exemption from, or to avoid an action or proceeding by, any
Governmental Entity, (ii) the obtaining of all necessary consents, approvals,
waivers or exemption from non-governmental third parties; provided, however,
that if either party is obliged to make expenditures, or incur costs, expenses
or other liabilities to obtain the consent of any non-governmental party, it
shall consult reasonably with the other party upon reasonable notice prior to
making payment of any such amount, and in no event shall either Weeks or Duke
make payment of any such amount in excess of $5,000,000 in obtaining such
consents without obtaining the prior written 



                                       34
<PAGE>


consent of the other, which consent shall not unreasonably be withheld or
delayed, (iii) the defending of any lawsuits or other legal proceedings, whether
judicial or administrative, challenging the REIT Merger, this Agreement or the
OP Merger Agreement or the consummation of the transactions contemplated by this
Agreement or the OP Merger Agreement, including seeking to have any stay or
temporary restraining order entered by any court or other Governmental Entity
vacated or reversed, and (iv) the execution and delivery of any additional
instruments necessary to consummate the transactions contemplated by and to
fully carry out the purposes of, this Agreement or the OP Merger Agreement. In
connection with and without limiting the foregoing, Weeks, Duke and their
respective Boards of Directors shall (i) take all action necessary so that no
"fair price," "business combination," "moratorium," "control share acquisition"
or any other anti-takeover statute or similar statute enacted under state or
federal laws of the United States or similar statute or regulation (a "TAKEOVER
STATUTE") is or becomes applicable to the REIT Merger, the OP Merger, this
Agreement, the OP Merger Agreement or any of the other transactions contemplated
hereby or thereby and (ii) if any Takeover Statute becomes applicable to the
REIT Merger, the OP Merger, this Agreement, the OP Merger Agreement or any other
transaction contemplated hereby, take all action necessary so that the REIT
Merger, the OP Merger, this Agreement, the OP Merger Agreement and the other
transactions contemplated hereby or thereby may be consummated as promptly as
practicable on the terms contemplated by this Agreement and the OP Merger
Agreement and otherwise to minimize the effect of such Takeover Statute on the
REIT Mergers, the OP Merger and the other transactions contemplated by this
Agreement and the OP Merger Agreement. From the date hereof through the
Effective Time, Weeks and Weeks OP shall timely file with the SEC all Weeks SEC
Documents required to be so filed. From the date hereof through the Effective
Time, Duke and Duke OP shall timely file with the SEC all Duke SEC Documents
required to be so filed.

     (b) Weeks shall give prompt notice to Duke, and Duke shall give prompt
notice to Weeks, if (i) any representation or warranty made by it contained in
this Agreement that is qualified as to materiality becomes untrue or inaccurate
in any respect or any such representation or warranty that is not so qualified
becomes untrue or inaccurate in any material respect or (ii) it fails to comply
with or satisfy in any material respect any covenant, condition or agreement to
be complied with or satisfied by it under this Agreement; PROVIDED, HOWEVER,
that no such notification shall affect the representations, warranties,
covenants or agreements of the parties or the conditions to the obligations of
the parties under this Agreement.

     Section 5.4. AFFILIATES. Prior to the Closing Date, Weeks and Duke shall
exchange letters identifying all persons who are, at the time this Agreement is
submitted for approval to the shareholders of Weeks and Duke, their respective
"affiliates" for purposes of Rule 145 under the Securities Act. Weeks and Duke
shall use their respective commercially reasonable efforts to cause each of
their respective affiliates to deliver on or prior to the Closing Date a written
agreement substantially in the form attached as Exhibit I hereto.

     Section 5.5. TAX TREATMENT. Each of Duke and Weeks shall use its
commercially reasonable efforts to (a) cause the REIT Merger to qualify as a
tax-free reorganization under Section 368(a) of the Code, (b) cause the OP
Merger to qualify as a tax-deferred exchange for Weeks and the other holders of
Weeks OP Units, and (c) obtain the opinions of counsel referred to in Sections
5.1(b), 6.2(e) and 6.3(e).

     Section 5.6. NO SOLICITATION OF TRANSACTIONS. Subject to Section 7.1, each
of Duke and Weeks shall not directly or indirectly, through any officer,
director, employee, agent, investment banker, financial advisor, attorney,
accountant, broker, finder or other representative, initiate, solicit, encourage
or facilitate (including by way of furnishing nonpublic information or
assistance) any inquiries or the making of any proposal or other action that
constitutes, or may reasonably be expected to lead to, any Competing Transaction
(as defined below), or enter into or maintain or continue discussions or
negotiate with any person in furtherance of such inquiries or to obtain a
Competing Transaction, or agree to or 



                                       35
<PAGE>


endorse any Competing Transaction, or authorize or permit any of its officers,
directors, employees or agents, attorneys, investment bankers, financial
advisors, accountants, brokers, finders or other representatives to take any
such action. Each of Duke and Weeks shall notify the other in writing (as
promptly as practicable) of all of the relevant details relating to all
inquiries and proposals which it or any of its Subsidiaries or any such officer,
director, employee, agent, investment banker, financial advisor, attorney,
accountant, broker, finder or other representative may receive relating to any
of such matters and if such inquiry or proposal is in writing, each of Duke and
Weeks shall deliver to the other a copy of such inquiry or proposal. For
purposes of this Agreement, "COMPETING TRANSACTION" shall mean any of the
following (other than the transactions expressly provided for in this
Agreement): (i) any merger, consolidation, share exchange, business combination
or similar transaction involving Duke (or any of its Subsidiaries, including
Duke OP) or Weeks (or any of its Subsidiaries, including Weeks OP), as the case
may be; (ii) any sale, lease, exchange, mortgage, pledge, transfer or other
disposition of 20% or more of the assets of Duke and its Subsidiaries, taken as
a whole or Weeks and its Subsidiaries, taken as a whole, as the case may be, in
a single transaction or series of related transactions, excluding any bona fide
financing transactions which do not, individually or in the aggregate, have as a
purpose or effect the sale or transfer of control of such assets; (iii) any
tender offer or exchange offer for 20% or more of the outstanding equity
securities of Duke (or any of its Subsidiaries, including Duke OP), or Weeks (or
any of its Subsidiaries, including Weeks OP); or (iv) any public announcement of
a proposal, plan or intention to do any of the foregoing or any agreement to
engage in any of the foregoing.

     Section 5.7. PUBLIC ANNOUNCEMENTS. Duke, Duke OP, Weeks and Weeks OP will
consult with each other before issuing, and provide each other the opportunity
to review and comment upon, any press release or other public statements with
respect to the REIT Merger, the OP Merger or any other transactions contemplated
by this Agreement or the OP Merger Agreement, and shall not issue any such press
release or make any such public statement prior to such consultation, except as
may be required by applicable law, court process or by obligations pursuant to
any listing agreement with any national securities exchange. The parties agree
that the initial press release to be issued with respect to the REIT Merger and
the OP Merger will be in the form agreed to by the parties hereto prior to the
execution of this Agreement.

     Section 5.8. NYSE LISTING. Duke shall prepare and submit to the NYSE a
supplemental listing application covering the Duke Common Stock, Duke Series F
Preferred Stock and Duke Series H Preferred Stock issuable in the REIT Merger
and shall use its commercially reasonable efforts to have the NYSE approve for
listing, upon official notice of issuance, the Duke Common Stock, Duke Series F
Preferred Stock and any Duke Series H Preferred Stock to be issued in the REIT
Merger.

     Section 5.9. LETTERS OF ACCOUNTANTS.

     (a) Weeks shall use its reasonable best efforts to cause to be delivered to
Duke and Weeks "comfort" letters of Arthur Andersen LLP, Weeks' independent
public accountants, dated and delivered the date on which the Registration
Statement shall become effective and as of the Effective Time, and addressed to
Duke and Weeks, in form and substance reasonably satisfactory to Duke and Weeks
and reasonably customary in scope and substance for letters delivered by
independent public accountants in connection with transactions such as those
contemplated by this Agreement and the OP Merger Agreement.

     (b) Duke shall use its reasonable best efforts to cause to be delivered to
Weeks and Duke "comfort" letters of KPMG Peat Marwick, Duke's independent public
accountants, dated and delivered the date on which the Registration Statement
shall become effective and as of the Effective Time, and addressed to Weeks and
Duke, in form and substance reasonably satisfactory to Weeks and Duke and
reasonably customary in scope and substance for letters delivered by independent
public accountants in 



                                       36
<PAGE>


connection with transactions such as those contemplated by this Agreement and
the OP Merger Agreement.

     Section 5.10. TRANSFER AND GAINS TAXES; SHAREHOLDER DEMAND LETTERS. Duke
and Weeks shall cooperate in the preparation, execution and filing of all
returns, questionnaires, applications or other documents regarding any real
property transfer or gains, sales, use, transfer, value added stock transfer and
stamp taxes, any transfer, recording, registration and other fees and any
similar taxes which become payable in connection with the transactions
contemplated by this Agreement or the OP Merger Agreement (together with any
related interests, penalties or additions to tax, "TRANSFER AND GAINS TAXES").
From and after the Effective Time, Duke shall cause Duke OP to pay or cause to
be paid all Transfer and Gains Taxes. Within 30 days after the Effective Time,
Duke shall send the shareholder demand letters required by Treasury Regulation
ss. 1.857-8 to the appropriate shareholders of Weeks for Weeks' taxable year
ended on the Effective Time.

     Section 5.11. BENEFIT PLANS AND OTHER EMPLOYEE ARRANGEMENTS.

     (a) BENEFIT PLANS. Subject to subsection (b) below, upon and after the
Effective Time, Duke and Duke OP (or their respective successors or assigns)
shall provide benefits to former employees of Weeks and its Subsidiaries that
are no less favorable in the aggregate to such employees than those provided to
other similarly situated employees of Duke and Duke OP at any applicable time
after the termination of the benefits provided to such employees by Weeks and
the Weeks Subsidiaries. With respect to any Duke Benefit Plan which is an
"employee benefit plan" as defined in Section 3(3) of ERISA and any other
service based benefits (including vacations) in which employees of Weeks or Duke
or their respective Subsidiaries may participate, solely for purposes of
determining eligibility to participate, vesting and entitlement to benefits but
not for purposes of accrual of pension benefits, service with Weeks, Duke or any
of their respective Subsidiaries shall be treated as service with Duke or Duke
OP, as the case may be; PROVIDED, HOWEVER, that such service shall not be
recognized to the extent that such recognition would result in a duplication of
benefits under both a Weeks Benefit Plan and a Duke Benefit Plan (or is not
otherwise recognized for such purposes under the benefit plans of Duke or Duke
OP).

     (b) STOCK INCENTIVE PLANS.

         (i) As of the Effective Time, each outstanding Weeks Stock Option shall
be assumed by Duke and shall be deemed to constitute an option to acquire, on
the same terms and conditions as were applicable under such Weeks Stock Option
(including, without limitation, vesting and exercisability but without regard to
any provisions that would result in the acceleration of such vesting or
exercisability due to the execution and delivery of this Agreement or the
consummation of the transactions contemplated by this Agreement), the same
number of shares of Duke Common Stock as the holder of such Weeks Stock Option
would have been entitled to receive pursuant to the REIT Merger had such holder
exercised such Weeks Stock Option in full immediately prior to the Effective
Time at a price per share equal to the aggregate exercise price for the shares
subject to such Weeks Stock Option divided by the number of full shares of Duke
Common Stock deemed to be purchasable pursuant to such Weeks Stock Option;
PROVIDED, HOWEVER, that the number of shares of Duke Common Stock that may be
purchased upon exercise of such Weeks Stock Option shall not include any
fractional share but shall be rounded upward to the next whole number of shares,
or if rounding up would disqualify an option as an incentive stock option, shall
be rounded down to the nearest whole number and cash shall be paid to each
affected optionee as compensation for such fractional share based on the fair
market value of Duke Common Stock at the Effective Time. Shares of Duke Common
Stock received pursuant to the terms of this Agreement, in consideration for
shares of Weeks Common Stock which have been held by Weeks executives and which
are unvested and subject to forfeiture at the Effective Time pursuant to a
restricted stock award under a Weeks Stock Plan shall vest and be subject to
forfeiture in accordance with the terms of the applicable restricted 


                                       37
<PAGE>


stock award of Weeks Common Stock in the absence of the transactions
contemplated by this Agreement. Prior to the Effective Time, Weeks will use its
commercially reasonable efforts to obtain any necessary consents and shall (to
the extent permitted under the terms of the Weeks Stock Plans) make any
amendments to and take any actions in respect of any Weeks Stock Plans, Weeks
Stock Options or restricted stock award to the extent such consents or
amendments are necessary to give effect to the foregoing (including without
limitation, the elimination of any right to acceleration of exercisability or
vesting as a result of the completion of the transactions contemplated by this
Agreement).

     (ii) Each Duke Stock Option shall continue in accordance with its term and
conditions, including, without limitation, vesting and exercisability without
regard to any acceleration of such vesting and exercisability as a result of the
transactions contemplated by this Agreement. Prior to the Effective Time, Duke
will use its best efforts to obtain any necessary consents and make any
amendments to any Duke Stock Plans or Duke Weeks Stock Options to the extent
such consents or amendments are necessary to give effect to the foregoing.

     (iii) At the Effective Time, Duke shall assume the Weeks Stock Plans (such
Weeks Stock Plans having been amended as appropriate to take into account the
adjustments set forth in Section 5.11(b)(i)), and the compensation committee of
the Board of Directors of Duke shall administer the Weeks Stock Plans. At the
Effective Time, the Weeks Stock Plans shall be amended such that no further
options shall be issued thereunder.

     (c) CHANGE IN CONTROL AGREEMENTS. At the Effective Time, Weeks shall assign
and Duke shall assume by operation of this Agreement Weeks' obligations under
Weeks' Change in Control Agreements identified in Section 5.11(c) of the Weeks
Disclosure Letter.

     Section 5.12. INDEMNIFICATION; DIRECTORS' AND OFFICERS' INSURANCE.

     (a) (i) Weeks shall, and, from and after the Effective Time, the Surviving
Corporation and the Surviving Partnership (collectively, the "INDEMNIFYING
PARTIES") shall, indemnify, defend and hold harmless each person who is now or
has been at any time prior to the date hereof or who becomes prior to the
Effective Time, an officer or director of Weeks or any Weeks Subsidiary (the
"INDEMNIFIED PARTIES") against all losses, claims, damages, costs, expenses
(including attorneys' fees and expenses), liabilities or judgments or amounts
that are paid in settlement of, with the approval of the Indemnifying Parties
(which approval shall not be unreasonably withheld or delayed), or otherwise in
connection with any threatened or actual claim, action, suit, proceeding or
investigation based on or arising out of the fact that such person is or was a
director or officer of Weeks or any Weeks Subsidiary at or prior to the
Effective Time, whether asserted or claimed prior to, or at or after, the
Effective Time ("INDEMNIFIED LIABILITIES"), including all Indemnified
Liabilities based on, or arising out of, or pertaining to this Agreement, the
REIT Merger, the OP Merger or the transactions contemplated by this Agreement or
the OP Merger Agreement, in each case to the full extent a corporation is
permitted under the GBCC to indemnify its own directors or officers, as the case
may be (and the Surviving Corporation will pay expenses in advance of the final
disposition of any such action or proceeding to each Indemnified Party to the
full extent permitted by law subject to the limitations set forth in Section
5.12(a)(iii)).

         (ii) Any Indemnified Parties proposing to assert the right to be
indemnified under this Section 5.12 shall, promptly after receipt of notice of
commencement of any action against such Indemnified Parties in respect of which
a claim is to be made under this Section 5.12 against Weeks and, from and after
the Effective Time, the Surviving Corporation, notify the Indemnifying Parties
of the commencement of such action, enclosing a copy of all papers served. If
any such action is brought 


                                       38
<PAGE>


against any of the Indemnified Parties and such Indemnified Parties notify the
Indemnifying Parties of its commencement, the Indemnifying Parties will be
entitled to participate in and, to the extent that they elect by delivering
written notice to such Indemnified Parties promptly after receiving notice of
the commencement of the action from the Indemnified Parties, to assume the
defense of the action and after notice from the Indemnifying Parties to the
Indemnified Parties of their election to assume the defense, the Indemnifying
Parties will not be liable to the Indemnified Parties for any legal or other
expenses except as provided below and except for the reasonable costs of
investigation subsequently incurred by the Indemnified Parties in connection
with the defense. If the Indemnifying Parties assume the defense, the
Indemnifying Parties shall have the right to settle such action without the
consent of the Indemnified Parties; PROVIDED, HOWEVER, that the Indemnifying
Parties shall be required to obtain such consent (which consent shall not be
unreasonably withheld) if the settlement includes any admission of wrongdoing on
the part of the Indemnified Parties or any decree or restriction on the
Indemnified Parties or their officers or directors; PROVIDED, FURTHER, that no
Indemnifying Parties, in the defense of any such action shall, except with the
consent of the Indemnified Parties (which consent shall not be unreasonably
withheld), consent to entry of any judgment or enter into any settlement that
does not include as an unconditional term thereof the giving by the claimant or
plaintiff to such Indemnified Parties of a release from all liability with
respect to such action. The Indemnified Parties will have the right to employ
their own counsel in any such action, but the fees, expenses and other charges
of such counsel will be at the expense of such Indemnified Parties unless (i)
the employment of counsel by the Indemnified Parties has been authorized in
writing by the Indemnifying Parties, (ii) the Indemnified Parties have
reasonably concluded (based on advice of counsel) that there may be legal
defenses available to them that are different from or in addition to those
available to the Indemnifying Parties, (iii) a conflict or potential conflict
exists (based on advice of counsel to the Indemnified Parties) between the
Indemnified Parties and the Indemnifying Parties (in which case the Indemnifying
Parties will not have the right to direct the defense of such action on behalf
of the Indemnified Parties) or (iv) the Indemnifying Parties have not in fact
employed counsel to assume the defense of such action within a reasonable time
after receiving notice of the commencement of the action, in each of which cases
the reasonable fees, disbursements and other charges of counsel will be at the
expense of the Indemnifying Parties.

         (iii) It is understood that the Indemnifying Parties shall not, in
connection with any proceeding or related proceedings in the same jurisdiction,
be liable for the reasonable fees, disbursements and other charges of more than
one separate firm admitted to practice in such jurisdiction at any one time for
all such Indemnified Parties unless (a) the employment of more than one counsel
has been authorized in writing by the Indemnifying Parties, (b) any of the
Indemnified Parties have reasonably concluded (based on advice of counsel) that
there may be legal defenses available to them that are different from or in
addition to those available to other Indemnified Parties or (c) a conflict or
potential conflict exists (based on advice of counsel to the Indemnified
Parties) between any of the Indemnified Parties and the other Indemnified
Parties, in each case of which the Indemnifying Parties shall be obligated to
pay the reasonable fees and expenses of such additional counsel or counsels.

this Agreement, the REIT Merger, the OP Merger Agreement, the OP Merger and the
other transactions contemplated hereby and the OP Merger Agreement shall be paid
by the party incurring such cost or expense.

     (b) Weeks agrees that if this Agreement shall be terminated pursuant to

or (f) and within 12 months following such termination Weeks or Weeks OP shall
consummate a Competing Transaction or enter into a definitive agreement
providing for a Competing Transaction or (y) this Agreement is terminated
pursuant to Section 8.1(h) or (j), then Weeks will pay as directed by Duke a fee
in an amount equal to the Duke Break-Up Fee (as defined below) less any Duke
Break-Up Expenses. Payment of any of such amounts shall be made, as directed by

(the "BASE AMOUNT") or (ii) the sum of (A) the maximum amount that can be paid
to Duke or Duke OP for the taxable year in which this Agreement is terminated
without causing Duke to fail to meet the requirements of Sections 856(c)(2) and
(3) of the Code determined as if the payment of such amount did not constitute
income described in Sections 856(c)(2) and (3) of the Code ("QUALIFYING
INCOME"), as determined by outside counsel or independent accountants to Duke,
and (B) in the event Duke receives a letter from outside counsel (the "DUKE
BREAK-UP FEE TAX OPINION") indicating that Duke has received a ruling from the
IRS holding that the receipt by Duke or Duke OP of the Base Amount would either
constitute Qualifying Income as to Duke with respect to Duke's proportionate
share thereof or would be excluded from Duke's gross income for purposes of
Sections 856(c)(2) and (3) of the Code (the "REIT REQUIREMENTS"), the Base
Amount less the amount payable under clause (A) above. In the event that Duke OP
is not able to receive the full Base Amount, Weeks shall place the unpaid amount
in escrow and shall not release any portion thereof to Duke or Duke OP unless
and until Weeks receives any one or a combination of the following: (i) a
letter(s) from Duke's outside counsel or independent accountants indicating the

not be treated as included in the income of Weeks for any prior taxable year, in
which event such maximum amount shall be paid to Duke OP, or (ii) a Duke

provision) shall terminate (and any amount still held in such escrow shall be
released to Weeks) on the date that is five years from the date the Duke
Break-Up Fee first becomes due under this Agreement. The "DUKE BREAK-UP
EXPENSES" shall be an amount equal 



                                       46

with this Agreement and the other transactions (including, without limitation,
all attorneys', accountants' and investment bankers' fees and expenses) but in
no event in an amount greater than $5,000,000 (such amount not to exceed such
$5,000,000 being referred to in this Section 8.2(b) or (c) as the "DUKE EXPENSE
FEE BASE AMOUNT") and (ii) the sum of (A) the maximum amount that can be paid to
Duke OP without causing Duke to fail to meet the requirements of Sections
856(c)(2) and (3) of the Code determined as if the payment of such amount did
not constitute Qualifying Income, as determined by outside counsel or
independent accountants to Duke and (B) in the event Duke receives a Duke
Break-Up Fee Tax Opinion indicating that Duke has received a ruling from the IRS
holding that Duke OP's receipt of the Duke Expense Fee Base Amount would either
constitute Qualifying Income as to Duke with respect to Duke's proportionate
share thereof or would be excluded from Duke's gross income for purposes of the
REIT Requirements, the Duke Expense Fee Base Amount less the amount payable
under clause (A) above. In the event that Duke is not able to receive the full
amount of the Duke Break-Up Expenses, Weeks shall place the unpaid amount in
escrow and shall not release any portion thereof to Duke OP unless and until
Weeks receives any one or combination of the following: (i) a letter(s) from
Duke's outside counsel or independent accountants indicating the maximum amount
that can be paid at that time to Duke OP without causing Duke to fail to meet
the REIT Requirements for any relevant taxable year together with an IRS ruling
or opinion of tax counsel to the effect that such payment would not be treated
as included in income for any prior taxable year, in which event such maximum
amount shall be paid to Duke OP, or (ii) a Duke Break-Up Fee Tax Opinion
indicating that Duke's receipt of the Expense Fee Base Amount would satisfy in
whole or in part the REIT Requirements, in which event Weeks shall pay to Duke
OP the unpaid Duke Expense Fee Base Amount. Weeks' obligation to pay any unpaid
portion of the Duke Break-Up Expenses (provided Weeks has otherwise complied
with its obligations under this provision) shall terminate (and any amount still
held in such escrow shall be released to Weeks) on the date that is five years
from the date the Duke Break-Up Expenses first become due under this Agreement.

     (c) Duke agrees that if this Agreement shall be terminated pursuant to
Section 8.1(c), then Duke will pay, as directed by Weeks, an amount equal to the
Weeks Break-Up Expenses (as defined below). In addition, Duke and Duke OP agree
that if (x) this Agreement shall be terminated pursuant to Section 8.1(c) or (g)
and within 12 months following such termination Duke or Duke OP shall consummate
a Competing Transaction or enter into a definitive agreement providing for a
Competing Transaction or (y) this Agreement is terminated pursuant to Section
8.1(i) or (k), then Duke or Duke OP will pay as directed by Weeks a fee in an
amount equal to the Weeks Break-Up Fee (as defined below) less any Weeks
Break-Up Expenses. Payment of any of such amounts shall be made, as directed by
Weeks, by wire transfer of immediately available funds promptly, but in no event
later than two business days after the amount is due as provided herein. The

(the "BASE AMOUNT") and (ii) the sum of (A) the maximum amount that can be paid
to Weeks without causing it to fail to meet the requirements of Sections
856(c)(2) and (3) of the Code determined as if the payment of such amount did
not constitute Qualifying Income, as determined by independent accountants to
Weeks and (B) in the event Weeks receives a letter from outside counsel (the
"WEEKS BREAK-UP FEE TAX OPINION") indicating that Weeks has received a ruling
from the IRS holding that Weeks' receipt of the Base Amount would either
constitute Qualifying Income or would be excluded from gross income for purposes
of Sections 856(c)(2) and (3) of the Code, the Base Amount less the amount
payable under clause (A) above. In the event that Weeks is not able to receive
the full Base Amount, Duke shall place the unpaid amount in escrow and shall not
release any portion thereof to Weeks unless and until Duke receives any one or a
combination of the following: (i) a letter(s) from Weeks' outside counsel or
independent accountants indicating the maximum amount that can be paid at that
time to Weeks without causing Weeks to fail to meet the REIT Requirements for
any relevant taxable year together with an IRS ruling or opinion of tax counsel
to the effect that such payment would not be treated as included in income for
any prior taxable year, in which even such maximum amount shall be paid to Weeks
OP, or (ii) a Weeks Break-Up Fee Tax Opinion, in which event Duke shall pay to
Weeks the

unpaid Base Amount. Duke's obligation to pay the Weeks Break-Up Fee (provided
Duke has otherwise complied with its obligations under this provision) shall
terminate (and any amount still held in such escrow shall be released to Duke)
on the date that is five years from the date the Weeks Break-Up Fee first
becomes due under this Agreement. The "WEEKS BREAK-UP EXPENSES" shall be an
amount equal to the lesser of (i) Weeks' out-of-pocket expenses incurred in
connection with this Agreement and the other transactions (including, without
limitation, all attorneys', accountants' and investment bankers' fees and
expenses) but in no event in an amount greater than $5,000,000 (such amount not
to exceed such $5,000,000 being referred to in this Section 8.2(d) or (e) as the
"WEEKS EXPENSE FEE BASE AMOUNT") and (ii) the sum of (A) the maximum amount that
can be paid to Weeks without causing it to fail to meet the requirements of
Sections 856(c)(2) and (3) of the Code determined as if the payment of such
amount did not constitute Qualifying Income, as determined by independent
accountants to Weeks and (B) in the event Weeks receives a Weeks Break-Up Fee
Tax Opinion indicating that Weeks has received a ruling from the IRS holding
that Weeks' receipt of the Weeks Expense Fee Base Amount would either constitute
Qualifying Income or would be excluded from gross income for purposes of the
REIT Requirements or that receipt by Weeks of the remaining balance of the Weeks
Expense Fee Base Amount following the receipt of and pursuant to such ruling
would not be deemed constructively received prior thereto, the Expense Fee Base
Amount less the amount payable under clause (A) above. In the event that Weeks
is not able to receive the full Weeks Expense Fee Base Amount, Duke and Duke OP
shall place the unpaid amount in escrow and shall not release any portion
thereof to Weeks OP unless and until Duke receives any one or combination of the
following: (i) a letter(s) from Weeks' outside counsel or independent
accountants indicating the maximum amount that can be paid at that time to Weeks
OP without causing Weeks to fail to meet the REIT Requirements for any relevant
taxable year together with an IRS ruling or opinion of tax counsel to the effect
that such payment would not be treated as included in income for any prior
taxable year, in which event such maximum amount shall be paid to Weeks OP, or
(ii) a Weeks Break-Up Fee Tax Opinion indicating that Weeks' receipt of the
Weeks Expense Fee Base Amount would satisfy in whole or in part the REIT
Requirements, in which event Duke shall pay to Weeks OP the lessor of the unpaid
Weeks Expense Fee Base Amount. Duke's obligation to pay any unpaid portion of
the Weeks Break-Up Expenses (provided Duke has otherwise complied with its
obligations under this provision) shall terminate (and any amount still held in
such escrow shall be released to Duke) on the date that is five years from the
date the Weeks Break-Up Expenses first become due under this Agreement.

     (d) In the event that any of Duke or Weeks is required to file suit to seek
all or a portion of the amounts payable under this Section 8.2, and such party
prevails in such litigation, such party shall be entitled to all expenses,
including attorney's fees and expenses which it has incurred in enforcing its
rights hereunder; PROVIDED that such expenses shall be considered part of
out-of-pocket expenses incurred in connection with this Agreement and the other
transactions within the definition of Duke Break-Up Expenses or Weeks Break-Up
Expenses, as the case may be.

     Section 8.3. EFFECT OF TERMINATION. In the event of termination of this
Agreement by either Weeks or Duke as provided in Section 8.1, this Agreement
shall forthwith become void and have no effect, without any liability or
obligation on the part of Duke, or Weeks, other than the last sentence of
Section 5.2, Section 8.2, this Section 8.3 and Article IX and except to the
extent that such termination results from a willful breach by a party of any of
its representations, warranties, covenants or agreements set forth in this
Agreement.

     Section 8.4. AMENDMENT. This Agreement may be amended by the parties in
writing by action of their respective Boards of Directors at any time before or
after any Stockholder Approvals, the Weeks OP Approvals and the Duke OP
Approvals are obtained and prior to the filing of the Articles of Merger for the
Merger with the Secretary of State of Indiana and the Secretary of State of
Georgia and a certificate of merger for the OP Merger with the Office of the
Secretary of State of Indiana and the Office of the Secretary of State of
Georgia; PROVIDED, HOWEVER, that, after any of the Stockholder Approvals, the



                                       48
<PAGE>


Weeks OP Approvals and the Duke OP Approvals are obtained, no such amendment,
modification or supplement shall alter the amount or change the form of the
consideration to be delivered to Weeks' or Duke's shareholders or alter or
change any of the terms or conditions of this Agreement if such alteration or
change would adversely affect Weeks' shareholders or Duke's shareholders, or the
Weeks Limited Partners or Duke Limited Partners.

     Section 8.5. EXTENSION; WAIVER. At any time prior to the Effective Time,
each of Weeks and Duke may (a) extend the time for the performance of any of the
obligations or other acts of the other party, (b) waive any inaccuracies in the
representations and warranties of the other party contained in this Agreement or
in any document delivered pursuant to this Agreement or (c) subject to the
proviso of Section 8.4, waive compliance with any of the agreements or
conditions of the other party contained in this Agreement. Any agreement on the
part of a party to any such extension or waiver shall be valid only if set forth
in an instrument in writing signed on behalf of such party. Any waivers pursuant
to clause (c) of the second preceding sentence (i) of the provisions of Section
4.1(e) may be given in writing by or on behalf of Duke by the chief executive
officer of Duke and (ii) of the provisions of Section 4.2(e) may be given in
writing by or on behalf of Weeks by the chief executive officer of Weeks. The
failure of any party to this Agreement to assert any of its rights under this
Agreement or otherwise shall not constitute a waiver of those rights.

                                    EXHIBIT J


         Duke and Duke OP agree to amend and restate the Duke OP Agreement
effective as of the effective time of the OP Merger to provide for the
following:

         (i) Provisions mutually satisfactory to the respective tax counsel for
Weeks OP and Duke OP which will (a) permit any former limited partner of Weeks
OP (as well as current or future limited partners of Duke OP) to elect, prior to
the effective time of the OP Merger, to be liable to restore to Duke OP, upon
liquidation of the partner's interest in Duke OP, up to a stated dollar amount
(the "Deficit Election Amount") of the negative balance existing in such
partner's capital account at the time of such liquidation (such amount to be
specified by the partner in his election, but subject to the requirement that
such election amount be reasonably related to the amount of recourse debt needed
by such partner to avoiding triggering taxable income attributable to his
negative tax capital account), (b) provide appropriate allocations of Duke OP
taxable net profit and net loss, in conformity with the regulations under
Section 704(b) of the Code, so that such partner is allocated for federal income
tax purposes an amount of Duke OP recourse indebtedness equal to such Deficit
Election Amount, and (c) contain such other provisions as Weeks and Duke shall
mutually agree which are necessary or appropriate to achieve such objective and
permitting a deceased partner's estate to elect to terminate its deficit make-up
election.

         (ii) A commitment by Duke OP to use commercially reasonable efforts to
maintain at all times during the period commencing at the effective time of the
OP Merger and ending on the tenth anniversary thereof an amount of outstanding
Duke OP indebtedness that is treated as "recourse debt" within the meaning of
Treasury Regulation ss. 1.752-1(a)(1) equal to or greater than the aggregate
amount of Duke OP recourse indebtedness as to which one or more current or
future partners of Duke OP have agreed, or will agree in the future, to bear the
economic risk of loss through deficit make-up obligations, indemnity agreements,
or otherwise (the "Target Recourse Debt Amount"). The Duke limited partners who
were limited partners of Weeks OP immediately prior to the OP Merger shall be
permitted to assume deficit make-up obligations which will cause them to bear
the economic risk of loss of up to an aggregate of up to $100 million and in the
future will be given proportionate opportunities to increase such amounts on the
same basis as is provided generally to limited partners of Duke OP.
Notwithstanding the foregoing, Duke OP shall have the right to cause the amount
of outstanding Duke OP indebtedness that is treated as recourse debt within the
meaning of Treasury Regulation ss. 1.752-1(a)(1) to fall below the Target
Recourse Debt Amount if the general partner of Duke OP determines, in good
faith, that such action is in the best economic interest of Duke OP and its
partners (without taking into account the tax consequences of taking such
action).

         (iii) Appropriate provisions to replicate in the Duke OP partnership
agreement the terms of the outstanding Series A, Series C and Series D classes
of preferred OP Units, including all relevant distribution and tax allocation
provisions. In addition, the allocations provided in the amended and restated
Duke OP partnership agreement will have substantial economic effect, within the
meaning of Section 704(b)(2) of the Code, and the partnership agreement will
provide that no liabilities of Duke OP will be allocated under Section 752 of
the Code to the holder of the Duke OP preferred partnership units issued to the
current holder of the Series C Preferred Partnership Units of Weeks OP.

         (iv) A provision requiring approval of the Asset Committee of the Duke
Board of any proposed sale of properties acquired from Weeks OP in the OP Merger
which have an aggregate gross value in excess of $50 million, with all
properties that are sold as part of a single transaction or in one or more
related transactions being aggregated to determine whether the $50 million
threshold is exceeded, if it is reasonably likely that the proposed sale will
result in adverse tax consequences to the unitholder or 


                                    Exh. J-1

<PAGE>

holders who contributed such properties to Weeks OP. This approval requirement
shall terminate after the tenth anniversary of the Closing Date.

         (v) A provision requiring Duke and Duke OP to use of the "traditional
method" under Treasury Regulation ss. 1.704-3(b) to account for differences
between the tax basis of the properties acquired from Weeks OP in the OP Merger
and their agreed upon value, including any such basis-value differentials that
existed which such properties were originally acquired by Weeks OP.

         (vi) Provisions providing for the assumption by Duke and Duke OP of the
lock-up restrictions and other undertakings set forth in Section 3.1(m)(iii) of
the Weeks Disclosure Letter.

         (vii) Provide for the withdrawal of the current General Partner, Duke,
from Duke OP to be replaced by a wholly owned subsidiary of Duke as the new
General Partner and in connection therewith, to provide for the transfer of
Duke's General Partner units to the new General Partner. Duke will remain a
limited partner in Duke OP.

         (viii) Allow for pledges of units in Duke OP without the consent of the
General Partner. Duke OP shall not, however, become subject to or assume any
liabilities or obligations, or become bound in any other way pursuant to such
pledges.

         (ix) Allow for uncertificated OP Units.

and/or the limited partners of Falcons OP, as the case may be, and at any
adjournment or postponements thereof (each, a "MEETING"), or pursuant to any
written consent in lieu of a meeting or otherwise.

                  (b) In the event that Colts is unable or declines to exercise
the power and authority granted by the Proxy for any reason, each of the Falcons
Stockholders and the Falcons OP Unitholders covenant and agree to vote or cause

contemplated in connection therewith at any Meeting and, upon request of Colts,
to provide their written consent thereto.

                  (c) The Falcons Stockholders hereby covenant and agree that
they will not vote, cause to be voted or take any action by written consent of

received by the Falcons OP Unitholders.

         2. COVENANTS BY THE FALCONS STOCKHOLDERS. The Falcons Stockholders,
individually, hereby covenant and agree that they will not, and will not agree
to, directly or indirectly, sell, transfer, assign, pledge, hypothecate, cause
to be redeemed or otherwise dispose of any of the Falcons Shares, or grant any
proxy, power-of-attorney or other authorization or interest in or with respect
to such Falcons Shares, or deposit such Falcons Shares into a voting trust or
enter into a voting agreement or arrangement with respect to such Falcons Shares
unless and until they shall have taken all actions (including, without
limitation, the endorsement of a legend on the certificates evidencing such
Falcons Shares) necessary to ensure that such Falcons Shares shall at all times
be subject to the rights, powers and privileges granted or conferred, and
subject to all restrictions, covenants and limitations imposed, by this
Agreement and shall have caused any transferee of any of the Falcons Shares to
execute and deliver to the other party hereto, an Agreement and Irrevocable
Proxy consistent with the terms contained herein.

indirectly, sell, transfer, assign, pledge, hypothecate, cause to be redeemed or
otherwise dispose of any of the Falcons OP Units, or grant any proxy,
power-of-attorney or other authorization or interest in or with respect to such

limitations imposed, by this Agreement and shall have caused any transferee of
any of the Falcons OP Units to execute and deliver to the other party hereto, an
Agreement and Irrevocable Proxy consistent with the terms contained herein.

         4. REPRESENTATION AND WARRANTY. Each of the Falcons Stockholders and
the Falcons OP Unitholders represents and warrants to Colts that he, she, or it
has full power and authority to enter into this Agreement, to grant the Proxy
and to perform its obligations hereunder.

         5. Miscellaneous.

                  (a) The terms and provisions of this Agreement shall be
governed by and construed in accordance with the laws of the State of Indiana
without giving effect to the conflicts of law provisions thereof.

                  (b) EACH OF THE FALCONS STOCKHOLDERS, THE FALCONS OP
UNITHOLDERS AND COLTS AGREE THAT THE PROXY AND ALL OTHER POWER AND AUTHORITY
INTENDED TO BE CONFERRED HEREBY ARE COUPLED WITH AN INTEREST SUFFICIENT IN LAW
TO SUPPORT AN IRREVOCABLE POWER AND SHALL NOT BE TERMINATED BY ANY ACT OF THE
FALCONS STOCKHOLDERS, THE FALCONS OP UNITHOLDERS OR COLTS , BY LACK OF
APPROPRIATE POWER OR AUTHORITY OR BY THE OCCURRENCE OF ANY OTHER EVENT OR EVENTS
EXCEPT AS PROVIDED HEREIN.

                  (c) THIS POWER OF ATTORNEY SHALL NOT BE AFFECTED BY THE DEATH
OR DISABILITY OF ANY FALCONS STOCKHOLDER OR FALCONS OP UNITHOLDER.

                  (d) This Agreement and the Proxy granted hereunder shall
terminate immediately upon the termination of the REIT Merger Agreement or the
consummation of the transactions contemplated thereby.

                  (e) Each of the Falcons Stockholders and the Falcons OP
Unitholders acknowledge and agree that performance of their respective
obligations hereunder will confer a unique benefit on Colts and that a failure
of performance will result in irreparable harm to the other and will not be
compensable by money damages. The parties therefore agree that this Agreement,
including the Proxy, shall be specifically enforceable and that specific
enforcement and injunctive relief shall be remedies properly available to the
other party for any breach of any agreement, covenant or representation of the
other hereunder. The terms and provisions of this Agreement shall be binding
upon, inure to the benefit of, and be enforceable by and against the personal
representatives, heirs, successors and assigns of the parties hereto.

                                       3
<PAGE>

                  (f) Each of the Falcons Stockholders and the Falcons OP
Unitholders will, upon request, execute and deliver any additional documents and
take such further actions as may reasonably be deemed by Colts to be necessary
or desirable to complete the proxies granted herein or to carry out the
provisions hereof.

                  (g) If any term, provision, covenant or restriction of this
Agreement, or the application thereof to any circumstance, shall, to any extent,
be held by a court of competent jurisdiction to be invalid, void or
unenforceable, the remainder of the terms, provisions, covenants and
restrictions of this Agreement or the application thereof to any other
circumstance, shall remain in full force and effect, shall not in any way be
affected, impaired or invalidated and shall be enforced to the fullest extent
permitted by law.

                  (h) This Agreement may be executed in counterparts, each of
which shall be deemed to be an original but all of which together shall
constitute one and the same document.

                  IN WITNESS WHEREOF, the Falcons Stockholders, Falcons OP
Unitholders and Colts have duly executed this Agreement or caused this Agreement
to be duly executed as of the date first above written.

    Duke Realty Investments and Weeks Corporation Announce Agreement to Merge
            ---------------------------------------------------------

     $1.7 billion transaction to create a dominant $5.2 billion diversified
                 real estate company with a significant presence
                         in the Midwest and the Sunbelt
               ---------------------------------------------------

      Merger will combine REIT industry's most consistent growth companies

         INDIANAPOLIS AND ATLANTA -- Duke Realty Investments, Inc., (DRE/NYSE)
and Weeks Corporation (WKS/NYSE) announced today that they have agreed to merge
their operations. The combination will create a diversified real estate company
with a total market capitalization in excess of $5.2 billion. The combined
company will be a preeminent real estate investment trust (REIT), specializing
in industrial and office buildings and business parks with 13 key geographic
platforms throughout the Midwest and the Sunbelt.

         The combined company, which will operate under the name Duke-Weeks
Realty Corporation, will have more than 90 million square feet of primarily
industrial and office properties and will own or control nearly 4,650 acres of
undeveloped land that management estimates can support an additional 63 million
square feet of future development. Duke-Weeks together will become an even
stronger competitor in the industrial/office REIT arena with more than $500
million in revenue from approximately 5,000 tenants, more than 1,300 employees,
and greater market presence and geographic diversity.

                                    -more-
<PAGE>

         The merger also brings together the entire management and operations of
the industry's most consistent growth companies: Duke and Weeks are the two
REITs with the longest ongoing records (at least 13 consecutive quarters) of
double-digit FFO growth per share. Duke and Weeks are also two of the real
estate industry's most acclaimed companies. Weeks Corporation was recently named
Industrial Developer of the Decade in Atlanta by the ATLANTA BUSINESS CHRONICLE,
and Duke was listed as the top-performing equity REIT for the past five years in
the WALL STREET JOURNAL's ranking of 1,000 major U.S. companies.

         Under the terms of the merger agreement, which was unanimously approved
by the Boards of Directors of both companies, each of Weeks' common shares will
be exchanged for 1.38 shares of Duke common stock. Based on Duke's closing price
of $21.8125 per share on February 26, 1999, the total merger consideration,
including assumption of debt and preferred stock, is approximately $1.7 billion.
Weeks' shareholders will own approximately 28 percent of the combined company on
a diluted basis.

         Following the close of the merger, which is expected in the second
quarter of 1999, and subject to changes in market or operating conditions,
Duke-Weeks intends to increase its dividend to an annualized level of at least
$1.48 per share, an 8.8 percent increase over Duke's current annualized dividend
of $1.36 per share. Adjusted for the exchange ratio, this dividend increase will
more than preserve the current level of dividend income to Weeks' shareholders.

         Upon completion of the transaction, Thomas L. Hefner, chairman,
president and chief executive officer of Duke, will be chairman and chief
executive officer of Duke-Weeks, headquartered in Indianapolis, Indiana. A. Ray
Weeks, Jr., chairman and chief executive officer of Weeks Corporation, will
become vice chairman, president, and chief operating officer of Duke-Weeks. Mr.
Weeks will be based in Atlanta, where the new company will maintain its primary
hub for the Sunbelt. In addition to the integration of the two management teams,
the Board of the combined company will comprise a broad representation of
current Duke and Weeks directors, with a majority of the directors from Duke's
Board.

         Among the near-term strategic priorities of Duke-Weeks will be
increasing market share in its existing cities, seizing the opportunities
created by the combined base of tenants, and expanding further into other major
growth markets in the Midwest and Sunbelt.

                  Tom Hefner said: "We are extremely pleased to expand our
         geographic presence through a merger with such a closely matched
         company. Duke and Weeks both have a record of consistent double-digit
         earnings growth and leadership in customer service, product
         development, technology, and capital market strategies. We believe that
         the long-term winners in this business will be those companies, like
         Duke and Weeks, with the proven ability to add value for tenants and
         shareholders alike through a vertically integrated operating company
         platform. Although we believe this transaction will add approximately
         four to five cents per share next year to our annual funds from
         operations before any modest cost savings are considered, we are
         merging primarily because we are convinced that together we will be
         able to enhance our long-term growth rate.

                  "In that regard," he continued, "I would like to emphasize
         what this merger is and is not about. This merger is about enhancing
         top-line revenue growth both internally and externally. It's about
         combining two of the most experienced and most respected management
         teams in the business, with an average of 17 years of real estate
         experience among the top officers. And, equally important, this merger
         is about combining the job growth and other highly positive demographic
         trends of the Sunbelt with the consistency and solid performance of the
         Midwest. This merger is NOT simply about getting bigger, about
         short-term accretion, or about cutting the resources that have made our
         companies the successes they are."

                  Ray Weeks said: "Each of our companies has a proud and
         successful history of accomplishment. For more than 25 years, Duke and
         Weeks have been delivering the highest quality real estate services to
         their respective customers in the Midwest and the Sunbelt. But even
         more important than our proven track records is our shared vision to
         create a formidable industrial and office real estate company best
         positioned to serve its customers from Minneapolis to Miami and
         virtually every major market in between."


         Merrill Lynch & Co. is acting as the financial advisor for Duke, and
Goldman, Sachs & Co. is acting as the financial advisor for Weeks. The merger is
subject to approval of both Duke's and Weeks' shareholders.

Key Reasons for the Merger



Value-Added Platforms -- Management at both Duke and Weeks believe that the

long-term winners in the real estate business will be those companies that truly

can add value for their customers through a high level of vertical integration.

As such, both Duke and Weeks have proven over the past 25-30 years that by first

focussing on customers' needs, they can also produce superior performance for

their investors. Particularly important components of the value-added process

are extensive development capabilities and undeveloped land holdings, strong

market positions, long-standing market knowledge and customer relationships, and

a portfolio of properties located primarily in controlled business park

environments.



As a combined company, Duke and Weeks will have a much broader platform to

extend their proven operating strategy into a wider geographic area encompassing

much of the eastern United States. Foremost in the combined Company's future

growth plans is to have an operational infrastructure that will allow it to

operate new properties in new markets as efficiently as it can in its existing

markets. Duke management believes that its merger with Weeks will allow it to

gain such an infrastructure several years sooner than if it otherwise tried to

build its own platform in the Sunbelt.



Demographics -- While its Midwestern markets are strong and stable, Duke

management believes that Weeks' markets offer higher potential for job growth

and absorption of office and industrial real estate.



Customer Synergies -- Duke has many clients with operations in Weeks' markets

and vice versa. The integration of the two companies will allow the combined

organization to better serve its base of satisfied customers in new regions of

the country.



Operational Synergies -- By combining the best practices of two highly

successful and complementary organizations, the combined Company believes that

it will be able to further refine its delivery system of operating and

developing suburban office and industrial real estate.



Market Synergies -- Duke currently has eight operating platforms (Indianapolis,

Cincinnati, Columbus, Cleveland, Minneapolis, Chicago, St. Louis, and

Nashville). Weeks currently has six operating platforms (Atlanta,

Raleigh-Durham, North/Central Florida, South Florida, Dallas and Nashville).

Duke-Weeks will have 13 operating platforms and will have dominant (at least 50

percent more square feet than the next largest competitor) positions in the

suburban office and industrial markets of Indianapolis, Cincinnati, Cleveland,

Columbus, and St. Louis, and will also have dominant positions in the Atlanta

and Nashville industrial markets.



Financial Position -- The combined company will have a $5.2 billion total market

capitalization made up of 68 percent equity and 32 percent debt. In the

immediate future, it is expected that the combined Company will benefit from

Duke's lower cost of debt and equity capital. Over time, Duke expects to be able

to access debt and equity capital more efficiently than it can currently because

of its increased size, diversification and growth prospects.

Questions & Answers Regarding the Transaction



1.    When will the proxy statement for the merger be on file? Both Duke and

      Weeks hope to file a joint proxy statement/prospectus regarding their

      merger by about March 22, 1999. Approximately 48 hours after the

      announcement of the merger and until the proxy statement is filed, both

      Duke and Weeks will be in a "quiet period" and are required to refrain

      from commenting about the transaction. Following the filing of the proxy

      statement and before shareholders vote on the merger, each company will be

      restricted to discussing information that is contained in the joint proxy

      statement/prospectus.



2.    How accretive will the transaction be? Management expects the transaction

      to add approximately four to five cents to Duke's funds from operations

      per share next year prior to considering any modest cost savings that may

      eventually result from the merger.



3.    What are your expected cost savings and when do you expect them to

      materialize? Cost savings are not an important reason for the merger and

      significant immediate cost savings are not expected since the Company

      expects to retain substantially all of both Duke's and Weeks' employees.

      As such, the Company will not provide an estimate of any future cost

      savings that may result from the transaction.



4.    Will you need to raise new equity capital as a result of this transaction?

      No, on a proforma basis, the combined Company will have a debt-to-total

      market capitalization ratio of 32 percent and interest and fixed-charge

      coverage ratios of 4.05 and 2.73, respectively. On an ongoing basis, both

      debt and equity capital will be raised when appropriate in the continuing

      operation of the Company's business.



5.    What will happen to the debt ratings of the post-merger company?

      Currently, Duke's senior unsecured debt ratings are BBB+ at Standard and

      Poors and Duff and Phelps, and Baa2 at Moodys. Following the merger with

      Weeks, the Company expects to continue to manage its balance sheet

      prudently and to maintain ample financial flexibility. While the Company

      cannot provide any assurance as to how the rating agencies will view its

      merger with Weeks, management believes that, on balance, the transaction

      will favorably affect the Company's credit quality. Specifically,

      management believes that its merger with Weeks will substantially mitigate

      the rating agency's previous concern about the Company's concentration in

      the Midwest.



6.    Are there any caps, collars, or breakup fees contained in the merger

      agreement? There are no caps, collars or any other mechanisms that would

      alter the exchange ratio of 1.38 Duke shares for each Weeks share. The

      definitive merger agreement specifies a breakup fee of $50 million.

7.    What will be the ongoing strategy of the combined company? The strategy of

      the combined Company is to blend the same basic strategy that both Duke

      and Weeks have historically deployed separately. Key components of this

      strategy include satisfying customer needs through a vertically integrated

      platform of real estate services, pursuing dominant positions in each

      market where it operates, utilizing each company's extensive development

      capabilities and land holdings, pursuing value-added acquisitions, and

      focusing on Class-A properties in business park environments with

      excellent long-term investment horizons. The Company also expects to blend

      the best practices of both Duke and Weeks to further refine its delivery

      system of real estate services.



8.    When will the combined company pay dividends and is the dividend changing?

      Duke has reviewed and increased its common stock dividend in the third

      quarter of each of the last several years. Subject to changes in market or

      operating conditions, it is the intent of Duke's Board to maintain its

      current quarterly common stock dividend of $0.34 per share for the second

      quarter of 1999, and then, following the merger, raise the quarterly

      dividend in the third quarter to at least $0.37 per share. This increase

      of at least 8.8 percent will allow Weeks shareholders to more than

      preserve their current level of dividend income following the merger.



      The combined Company expects to continue to pay quarterly common stock

      dividends according to Duke's current schedule of paying dividends on the

      last business day of February, May, August, and November.



      Dividends on both Duke's and Weeks' preferred stock issues are expected to

      continue to be paid in accordance with their original terms.



9.    Do you anticipate divesting any properties following the merger? Both Duke

      and Weeks routinely evaluate their properties and sometimes choose to sell

      certain properties that are no longer consistent with their investment

      focus. While this routine evaluation is expected to continue to result in

      property sales, the combined Company does not expect to "spin-off" any

      particular group of properties in the immediate future.



10.   What is the accounting treatment of the merger and what are the tax

      implications to Weeks shareholders? The purchase method of accounting will

      be used to account for the merger. Weeks common and preferred shareholders

      will convert to Duke shares via the merger on a tax-free basis and their

      basis and holding period in their shares will remain unchanged.



11.   Is the pending merger with Weeks a sign of things to come? After

      completion of the merger, the Company's top priority will be to integrate

      the Weeks organization as efficiently as possible. Over time, the merger

      with Weeks will give the combined organization a much broader platform to

      pursue future growth opportunities. With more than 90 percent of office

      and industrial real estate still held by private enterprises in the United

      States, the Company will continue to look at both private and public

      opportunities.
