                      AMERICAN INDUSTRIAL PROPERTIES REIT

                        6210 N. BELTLINE ROAD, SUITE 170
                              IRVING, TEXAS 75063


                                                            February      , 2001


Dear Fellow Shareholder:


     We invite you to attend a special meeting of shareholders of American
Industrial Properties REIT to be held on March      , 2001, at 9:00 a.m., local
time, at 2200 Ross Avenue,
floor, Dallas, Texas. The purpose of the special meeting is to vote upon two
proposals, that if both approved, will result in you receiving $     per common
share you own. You will be asked to vote on the following proposals:


     - the approval of the agreement and plan of merger with Developers
       Diversified Realty Corporation and DDR Transitory Sub Inc. and the
       transactions contemplated thereby, pursuant to which you will receive
       $     per common share in connection with the merger; and


     - the approval of the agreement of purchase and sale with Value Enhancement
       Fund IV, L.P. and the transactions contemplated thereby, pursuant to
       which 31 of our properties will be sold for $292.2 million, consisting of
       $     cash and the assumption of $     debt. The net proceeds of the sale
       of properties equates to approximately $     per common share
       outstanding.


Although you are being asked to vote on these proposals separately, if either
proposal is not approved, we will not close either of the transactions.


     The approval of the holders of 66 2/3% of our outstanding common shares is
required to approve each of the transactions. Shareholders beneficially owning
or having the right to vote approximately 70.7% of our outstanding common shares
have signed voting agreements or agreed with AIP to vote their shares in favor
of the two transactions. If they vote in accordance with those agreements, the
transactions will be approved; however, two of the shareholders that vote, on
behalf of their clients, 6.97% of our outstanding common shares signed voting
agreements that allow them to vote against the proposals if they determine that
the exercise of their fiduciary duties to their clients so requires.



     If the transactions are approved, DDR will be the sole remaining
shareholder of AIP, controlling AIP's remaining 39 properties. AIP will not be
publicly-traded and you will not have any ownership interest in AIP. The merger
is being financed from the proceeds of the sale of properties to Value
Enhancement Fund and cash generated from AIP's operations. If additional funds
are needed to close the merger, DDR will either pay the funds directly or cause
AIP to borrow the funds. If AIP sells all or substantially all of its properties
within six months after the effective date of the merger for a price in excess
of an agreed upon amount, you will receive a distribution of your pro rata share
of the excess. Otherwise, DDR is the sole beneficiary of any future earnings and
growth of AIP.


     In connection with the merger, Chase Securities Inc., the financial advisor
to our special committee, delivered to the special committee of the board of
trust managers, an opinion dated November 1, 2000 that, on the date of that
opinion, the cash consideration proposed to be paid to the holders of our common
shares in connection with the merger was fair from a financial point of view to
these holders. The written opinion of Chase Securities is attached as Appendix A
to the accompanying proxy statement, and you should read it carefully. The
special committee is comprised of one trust manager. Two other trust managers
resigned from the special committee before it made its recommendation on the
proposals.


     A MAJORITY OF THE TRUST MANAGERS NOT DESIGNATED BY DDR, ACTING ON THE
RECOMMENDATION OF THE REMAINING MEMBER OF THE SPECIAL COMMITTEE, HAS APPROVED
AND ADOPTED THE MERGER AGREEMENT AND THE PROPERTY SALE AGREEMENT AND THE
TRANSACTIONS CONTEMPLATED THEREBY. THEY BELIEVE THAT THE TRANSACTIONS ARE FAIR
TO, AND IN THE BEST INTERESTS OF, OUR SHAREHOLDERS. THEY RECOMMEND THAT YOU VOTE
FOR BOTH OF THE PROPOSALS. THE TWO TRUST MANAGERS WHO RESIGNED FROM THE SPECIAL
COMMITTEE VOTED AGAINST THE PROPOSALS. THEIR REASONS FOR RESIGNING FROM THE
SPECIAL COMMITTEE AND FOR VOTING AGAINST THE PROPOSALS ARE DISCUSSED ON PAGE 35
OF THE ACCOMPANYING PROXY STATEMENT.


     The accompanying proxy statement contains detailed information on the
proposed transactions. A copy of the merger agreement is attached as Appendix B
and a copy of the property sale agreement is attached as Appendix C to this
proxy statement. You should read them carefully.

     Whether or not you plan to attend the special meeting, it is important that
your shares are represented at the meeting. Not returning your proxy card or not
instructing your broker how to vote any shares held for you in street name will
have the same effect as a vote against the proposals. Accordingly, you are
requested to promptly complete, sign and date the enclosed proxy card and return
it in the envelope provided,
   3

whether or not you plan to attend. Doing so will not prevent you from voting
your shares in person if you later choose to attend the special meeting. If the
merger and the sale of properties are approved, you will receive instructions
for surrendering your share certificates and a letter of transmittal to be used
for this purpose. You
should not submit your share certificates for exchange until you have received
the instructions and the letter of transmittal.

Sincerely,

Charles W. Wolcott
President and Chief Executive Officer

ACCURACY OR ADEQUACY OF THE INFORMATION CONTAINED IN THIS DOCUMENT. ANY
REPRESENTATION TO THE CONTRARY IS A CRIMINAL OFFENSE.


     THIS PROXY STATEMENT IS DATED FEBRUARY      , 2001, AND, TOGETHER WITH THE

To the Shareholders of American Industrial Properties REIT:


     This is a notice that a special meeting of shareholders will be held on
March   , 2001, at 9:00 a.m., local time, at 2200 Ross Avenue,        floor,
Dallas, Texas. The purpose of this meeting is for our shareholders to:

       merger dated as of November 1, 2000, among American Industrial Properties
       REIT, DDR Transitory Sub Inc. and Developers Diversified Realty
       Corporation, and the transactions contemplated thereby, pursuant to which
       you will receive $     for each of our shares that you own.

     - Consider and vote on a proposal to approve the agreement of purchase and
       sale dated as of November 1, 2000, among American Industrial Properties
       REIT, certain of its affiliates and Value Enhancement Fund IV, L.P., and
       the transactions contemplated thereby, pursuant to which we will sell 31
       of our properties for $292.2 million.

     - Consider and act upon any other matters as may properly come before the
       special meeting.


     Your board of trust managers has determined that only holders of our common
shares at the close of business on February   , 2001, will be entitled to vote
at the special meeting. Approval of the merger and the sale of the properties
requires the holders of 66 2/3% of our common shares outstanding on the record
date to vote in favor of the proposals. A form of proxy and a proxy statement
containing more detailed information with respect to the matters to be
considered at the special meeting accompany and are a part of this notice to
shareholders.



     UNDER TEXAS LAW, YOU ARE ENTITLED TO DISSENTERS' RIGHTS IN CONNECTION WITH
THE MERGER. SEE PAGE 75 OF THE PROXY STATEMENT FOR A DESCRIPTION OF THOSE RIGHTS
AND THE PROCEDURES THAT YOU MUST FOLLOW TO EXERCISE YOUR RIGHTS.


     Regardless of whether you plan to attend the special meeting, please
complete, sign and date the enclosed proxy card and return it promptly in the
enclosed envelope. It is important that your shares be represented at the
special meeting. You may revoke your proxy by:

     - delivering to our corporate secretary, before the taking of the vote at
       the special meeting, a written notice of revocation bearing a later date
       than the date of the proxy, or a later-dated proxy relating to the same
       shares; or

     - attending the special meeting and voting in person.

                                            By Order of the Board of Trust

                               SUMMARY TERM SHEET

     This summary term sheet highlights information contained in this proxy
statement and may not contain all of the information that is important to you.
We urge you to read carefully this proxy statement, including the appendices and
the other documents we refer to in this proxy statement. In this proxy
statement, the terms "AIP," "we," "us" and "our" refer to American Industrial
Properties REIT.


     - Shareholder Vote -- You are being asked to approve two transactions, the
       completion of each of which is dependent on the approval of the other.
       First, you are being asked to approve and adopt the merger agreement, by
       which DDR Transitory Sub Inc. will be merged into AIP, resulting in
       Developers Diversified Realty Corporation being the sole shareholder of
       AIP. Second, you are being asked to approve and adopt a property sale
       agreement, by which we will sell immediately prior to the merger a
       portfolio of 31 of our properties to a private investment fund managed by
       Lend Lease Real Estate Investments, Inc. Please read "Proposal Number
       One: The Merger; Special Factors" beginning on page 25 and "Proposal
       Number Two: The Sale of Properties" beginning on page 76.



      Both the merger agreement and the property sale agreement must be approved
      and adopted by the affirmative vote of the holders of 66 2/3% of our
      outstanding common shares. Please read "The Special Meeting -- Required
      Vote" on page 24.



     - Payment -- In the merger, each of the issued and outstanding common
       shares owned by our shareholders, other than DDR, DDR Sub and their
       respective direct and indirect subsidiaries, will be converted into the
       right to receive $     in cash, without interest. In accordance with the
       merger agreement, that amount reflects a $1.27 reduction in the original
       amount of the merger consideration, resulting from a special distribution
       in that amount made to shareholders on January 17, 2001. The distribution
       was made to avoid having REIT taxable income for federal income tax
       purposes in connection with the sale of our Manhattan Towers property in
       November 2000. If all or substantially all of our properties remaining
       after the sale to Value Enhancement Fund are sold within six months after
       the effective date of the merger for more than an agreed upon amount, you
       may receive additional consideration. We sometimes refer to the per share
       amount to be paid in the merger as the "merger consideration." Please
       read "Proposal Number One: The Merger; Special Factors -- General
       Description" on page 25.


     - DDR Sub -- DDR Transitory Sub Inc., which we refer to as "DDR Sub," is a
       newly formed Texas corporation that is wholly-owned by Developers
       Diversified Realty Corporation, an Ohio corporation, which we refer to as
       "DDR."

     - Value Enhancement Fund -- Value Enhancement Fund IV, L.P., which we refer
       to as "Value Enhancement Fund," is a Georgia limited partnership that is
       managed by Lend Lease Real Estate Investments, Inc., which we refer to as
       "Lend Lease."


     - Continuing Shareholder -- Following completion of the merger, all shares
       of DDR Sub stock will become AIP common shares. DDR is the sole
       shareholder of DDR Sub and as a result will own all of our common shares
       following completion of the merger. Please read "The Merger
       Agreement -- Consequences of the Merger" on page 59.



     - Voting Agreements -- DDR has agreed with us to vote its common shares in
       favor of the proposals. Each of Morgan Stanley Dean Witter Investment
       Management Inc., on behalf of certain clients, MS Real Estate Special
       Situations Inc., LaSalle Investment Management, Inc., on behalf of
       certain clients, LaSalle Investment Management (Securities), LP, on
       behalf of certain clients, and USAA Real Estate Company, which, together
       with DDR, beneficially own or have the right to vote in the aggregate
       approximately 70.7% of our outstanding common shares on the record date,
       have entered into voting agreements

                                        1
   8


       with each of DDR and Value Enhancement Fund by which each of them has
       agreed to vote in favor of the proposals. If these shareholders vote as
       they have agreed to in the voting agreements and DDR votes as it has
       agreed with us, the proposals will be approved and adopted regardless of
       how any other shareholder votes on these issues. The voting agreements
       signed by the LaSalle entities allow them to vote against the proposals
       if in the exercise of their fiduciary duties to their investment advisory
       clients, they believe they should vote against the proposals. The LaSalle
       entities are entitled to vote 6.97% of our outstanding common shares.
       Please read "The Special Meeting -- Required Vote" on page 24.


     - Effects of the Transaction -- This is a "going private" transaction. As a
       result of the merger:

          - DDR will own AIP;


          - our shareholders other than DDR will no longer have any interest in
            our future earnings or growth;



          - we will no longer be a public company; and



          - our common shares will no longer be traded on the New York Stock
            Exchange.



     - Please read "The Merger Agreement -- Consequences of the Merger" on page
       59.



     - Tax Consequences -- Generally, the merger consideration will be taxable
       for U.S. federal income tax purposes. You will recognize taxable gain or
       loss in the amount of the difference between the amount of the merger
       consideration and your adjusted tax basis for each common share of AIP
       that you own. Please read "Proposal Number One: The Merger; Special
       Factors -- Material Federal Income Tax Consequences" on page 55.



     - Conditions -- The merger agreement and the sale of properties are subject
       to approval by our shareholders, compliance with certain financial
       covenants, and customary conditions and the closing of each transaction
       is conditioned on the closing of the other transaction. Please read "The
       Merger Agreement -- Conditions to the Merger" on page 63.



     - After the Merger -- Upon completion of the merger, DDR will own all of
       our common shares. You will not own any of our common shares after

             QUESTIONS AND ANSWERS ABOUT THE PROPOSED TRANSACTIONS

     The following questions and answers are intended to provide brief answers
to frequently asked questions concerning the merger and the proposed sale of
properties. These questions and answers do not, and are not intended to, address
all the questions that may be important to you. You should read carefully the
"Summary" section and the remainder of this document as well as the appendices
and the documents incorporated by reference in this document.

Q:   WHAT WILL HAPPEN IN THE TRANSACTIONS?

A:   If the transactions are approved, the sale of 31
     of our properties to Value Enhancement Fund will occur. Immediately
     following the sale of properties, DDR Sub will be merged into AIP. In the
     merger, all of your shares will be converted into the right to receive
     $     per share in cash and all shares in DDR Sub will be converted into
     AIP common shares. The result of the merger is that DDR will be the sole
     shareholder of AIP, controlling our remaining 39 properties and DDR will be
     relieved of its obligation to purchase additional common shares or
     preferred shares from AIP. If all or substantially all of our properties
     remaining after the sale to Value Enhancement Fund are sold within six
     months after the effective date of the merger for more than an agreed upon
     amount, you may receive additional consideration.

Q:   WHEN DO YOU EXPECT THE TRANSACTIONS TO BE
     COMPLETED?

A:   We are working to complete the transactions
     during the first quarter of 2001.

Q:   WHEN IS THE SPECIAL MEETING?


A:   March   , 2001.


Q:   WHO IS ENTITLED TO VOTE?


A:   All persons and entities that are holders of AIP
     common shares at the close of business on February   , 2001.


Q:   WHAT ARE WE BEING ASKED TO VOTE UPON?

A:   You are being asked to approve the merger of
     DDR Sub into AIP and, immediately preceding the merger, the sale of 31 of
     our properties to Value Enhancement Fund.

Q:   WHAT VOTE IS REQUIRED TO APPROVE THE
     TRANSACTIONS?

A:   Approval of each of the transactions requires
     the holders of 66 2/3% of our common shares outstanding on the record date
     to vote in favor of each of the transactions.

Q:   CAN DDR, AS A SHAREHOLDER OF AIP, VOTE ON
     THE TRANSACTIONS?

A:   Yes.

Q:   WHY DID THE BOARD FORM A SPECIAL COMMITTEE?

A:   Because four of our trust managers are
designees of DDR, one of our trust managers' employer has invested in DDR on
     behalf of its clients, and one of our employee trust managers would receive
     severance payments in connection with any change of control transaction.
     These circumstances create actual or potential conflicts of interest for
     those trust managers to which the special committee is not subject.
     Therefore, the board appointed a special committee of three disinterested
     trust managers to review and evaluate the proposals. Two of the three trust
     managers resigned from the special committee before it made its
     recommendation to the board on the proposals and subsequently voted against
     the proposals.


Q:   WHY DID TWO TRUST MANAGERS RESIGN FROM THE
     SPECIAL COMMITTEE?



A:   On August 10, 2000, Mr. Giles resigned from
     the special committee because he opposed the timing of the transactions.
     Mr. Giles believed that real estate was in a down market, that we should
     wait to sell until the market improved, and that the transactions would
     result in inadequate consideration to shareholders. Mr. Bricker resigned
     from the special committee on August 25, 2000 because he opposed the
     extension of an exclusivity agreement with Lend Lease and he opposed the
     proposed sale of properties to Lend Lease or its assignee because he
     believed it would result in an inadequate price.


                                        3
   10


Q:   WHY DID TWO TRUST MANAGERS VOTE AGAINST THE
     TRANSACTIONS?



A:   Because they do not believe the consideration
     being paid for the properties is sufficient to provide the shareholders
     with adequate consideration.


Q:   HOW DO THE BOARD OF TRUST MANAGERS AND THE
     SPECIAL COMMITTEE RECOMMEND THAT I VOTE?

     Our board of trust managers, acting on the recommendation of the remaining
     member of our special committee, by a vote of a majority of our trust
     managers not designated by DDR, has approved and recommended that
     shareholders vote For approval of the proposals. The sole member of the
     special committee and a majority of our trust managers not designated by
     DDR believe that the merger is fair to, and in the best interests of, our
     shareholders. The four trust managers that are designees of DDR abstained
     from voting on the proposals. Our two trust managers that are not employees
     or designees of our institutional shareholders resigned from the special
     committee before it made its recommendation regarding the proposals and
     thereafter voted against the proposals.

Q:   WHAT WILL HAPPEN TO MY COMMON SHARE
     DIVIDENDS?


A:   Under the merger agreement, we may pay a
     dividend only in the minimum amount necessary to avoid jeopardizing our
     status as a REIT under federal tax laws or to avoid having taxable income
     for federal income tax purposes. The merger agreement provides that the
     consideration per share you will receive in the merger would be reduced by
     the amount of any such dividend. On January 17, 2001, we made a special
     distribution of $1.27 per share to our shareholders of record on December
     29, 2000 to avoid having taxable income for fiscal year 2000. As a result,
     the initial merger consideration of $     per share has been reduced by
     $1.27. Accordingly, you are currently entitled to receive $     per share
     as merger consideration.



     We may also pay a dividend based on cash generated from operations if there
     is a delay of more than three days between the scheduled closing on
                 , 2001 and the actual closing date. Any dividend paid under
     that circumstance would not affect the amount of the merger consideration.


Q:   WHAT WILL HAPPEN TO AIP'S EXECUTIVE OFFICERS
     AFTER THE MERGER?

A.   They will no longer be employed by AIP.

Q:   WILL I OWE ANY U.S. FEDERAL INCOME TAXES AS A
     RESULT OF THE MERGER?

A.   The receipt of cash for common shares in the
     merger will be a taxable transaction for U.S. federal income tax purposes
     and may also be a taxable transaction under applicable state, local,
     foreign or other tax laws.

Q:   WHAT HAPPENS IF I TRANSFER MY SHARES AFTER THE
     RECORD DATE?

A:   The record date for the special meeting is
     earlier than the expected date of the transactions. Therefore, transferors
     of shares after the record date but prior to the transactions will retain
     their right to vote at the special meeting, but the right to receive the
     merger consideration will transfer with the shares.

Q:   WHAT DO I NEED TO DO NOW?

A:   Simply indicate on your proxy card how you
     want to vote and sign, date and mail it to us in the enclosed envelope as
     soon as possible.

Q:   WHAT HAPPENS IF I DO NOT RETURN A PROXY CARD?

A:   The failure to return your proxy card will have
     the same effect as voting against the proposals.

Q:   MAY I VOTE IN PERSON?

A:   Yes. You may attend the special meeting and
     vote your shares in person, rather than signing and mailing a proxy card.

Q:   MAY I CHANGE MY VOTE AFTER I HAVE VOTED?

A:   Yes. You may change your vote at any time
     before your proxy is voted at the special meeting by submitting a new proxy
     or you may attend the special meeting and vote in person. Simply attending
     the meeting will not revoke your proxy.

Q:   HOW WILL MY SHARES BE VOTED IF I RETURN A BLANK
     SIGNED PROXY CARD?

A:   Your proxy will be voted in favor of the
     proposals.

Q:   IF MY SHARES ARE HELD IN "STREET NAME" BY MY
     BROKER, WILL MY BROKER VOTE MY SHARES FOR ME?

A:   Your broker will vote your shares only if you
     provide instructions on how to vote. You should instruct your broker how to
     vote your shares, following the directions your broker provides. If you do
     not provide instructions to your broker, your shares will not be voted and
     they will be counted as votes against the transactions.

Q:   SHOULD I SEND MY SHARE CERTIFICATES NOW?

A:   No. After the merger is completed, you will
     receive written instructions for exchanging your share certificates.

Q:   WHO CAN HELP ANSWER MY QUESTIONS?

A:   If you have additional questions about the
     transactions, you should contact Tony Koeijmans at (972) 756-6000.

Q:   AM I ENTITLED TO EXERCISE ANY DISSENTERS' RIGHTS
     IN CONNECTION WITH THE MERGER?


A:   Yes. Your rights to dissent are described on
     page 75 and the procedures that you must follow to exercise your rights are
     set forth on pages 75-76.


Q:   WILL DDR SHAREHOLDERS BE REQUIRED TO VOTE ON
     THE MERGER AGREEMENT?

A:   No.

     We are a self-administered REIT focused on the light industrial property
sector, including office showroom, service center and flex properties, low-rise
office and small bay distribution buildings. AIP's portfolio of 70 properties
comprises approximately 7.5 million square feet in 11 states. We are based in
Irving, Texas and have acquired, managed and improved industrial and other
commercial properties since 1985.


          Developers Diversified Realty Corporation

          Web site: www.ddrc.com

     DDR is a Beachwood, Ohio based REIT that currently owns and manages 209
shopping centers in 40 states totaling 49.2 million square feet of real estate
under management. DDR is a self-administered and self-managed REIT operating as
a fully integrated real estate company which develops, leases and manages
shopping centers.

     DDR Sub was formed in August 2000 for the sole purpose of effectuating the
merger. DDR Sub is a subsidiary of DDR.

     DDR, as of the record date, owns 46.0% of our issued and outstanding common
shares and has the right to designate four of our trust managers.

OVERVIEW OF THE TRANSACTIONS

     Under the sale agreement, we will sell 31 of our properties to Value
Enhancement Fund for $292.2 million. Value Enhancement Fund is an investment
fund managed by Lend Lease. Neither Value Enhancement Fund nor Lend Lease is
affiliated with AIP. Neither of these entities directly owns any of our shares.


     Immediately following the sale of properties, DDR Sub will be merged into
us. Our shareholders, other than DDR, DDR Sub and their respective direct and
indirect subsidiaries, will receive $     for each of our shares they own. The
aggregate $     million we will pay to our shareholders in connection with the
merger will be funded from the sale of the 31 properties to Value Enhancement
Fund, the $34.2 million of net proceeds we received when we sold our Manhattan
Towers property and from operations. The amount of the consideration payable by
DDR and by Value Enhancement Fund was the result of extensive, arm's-length
negotiations between the special committee of the AIP board, consisting of trust
managers not designated by DDR and not employed by AIP, and its financial and
legal advisors, and representatives of DDR and of Lend Lease, the fund manager
of Value Enhancement Fund, respectively. The per share consideration to be
received by the shareholders of AIP, other than DDR, was agreed to only after
the sole remaining member of the special committee determined, based on the
opinion of Chase Securities, that the per share amount was fair from a financial
point of view to the AIP shareholders.


     While the proceeds from these sales and the expected cash generated from
operations are expected to be sufficient to pay the common share consideration
to the non-DDR shareholders, we may utilize such funds to pay down existing
lines of credit during the period prior to closing and then would reborrow the
funds as necessary under our existing lines of credit to make the cash payments
to the non-DDR shareholders at closing. In the merger, DDR Sub shares will be
converted into AIP shares. As a result, DDR will become the sole shareholder of
AIP, controlling our remaining 39 properties and DDR will be relieved

                                        6
   13

of its obligation to purchase additional common
shares or preferred shares from AIP. If AIP sells all or substantially all of
its properties remaining after the sale to Value Enhancement Fund during the six
months after the effective date of the merger, and if the net aggregate sale
price exceeds the aggregate agreed upon property values, you will receive a
distribution of your pro rata share of the excess.

     If either of the transactions is not approved, neither transaction will be
completed.


BENEFITS AND DETRIMENTS TO NON-DDR SHAREHOLDERS (See page 43)



     The principal benefits of the transactions to non-DDR shareholders are as
follows:



     - the $     per share merger consideration (including the $1.27 per share
      special distribution on January 17, 2001) represents a   % premium to the
      market price for AIP's common shares immediately prior to the announcement
      of the transactions; and



     - the elimination of the risk of a declining share price.



     The principal detriments to non-DDR shareholders are as follows:



     - you will cease to have an ownership interest in AIP and will, therefore,
      not participate in any future earnings or growth of AIP; and



     - if the cash you receive in the merger exceeds your tax basis in the
      common shares, you will recognize taxable gain upon the closing of the
      merger.



BENEFITS TO INSIDERS (See page 51)



     Some members of our board of trust managers and management have interests
in the merger that may conflict with your interests as a holder of our common
shares. As a result of the merger, our officers, trust managers, and parties
that designated some of our trust managers will receive a total of approximately
$     million in consideration for their shares, and severance payments, options
and dividend equivalent rights, as described below.



     - Our executive officers, Charles W. Wolcott, Marc A. Simpson, Lewis D.
      Friedland and David B. Warner, will receive severance, option cash out and
      dividend equivalent right cancellation payments totaling $     million in
      the aggregate. They will also have their medical benefits continued for a
      period of up to one year or the benefits will be cashed out. Mr. Wolcott
      also serves as a trust manager.



     - The LaSalle entities, which have one representative on our board, and
      which own beneficially, on behalf of certain clients, 7.6% of DDR's
      outstanding common shares, will receive $     for their shares on the same
      basis as our other shareholders.



     - DDR, our largest shareholder, which has four representatives on our
      board, will gain control of AIP and 39 of our remaining properties for the
      assumption of approximately $     of debt and all of our remaining
      obligations and liabilities after the merger. It will also be relieved of
      any future funding obligations under its July 1998 share purchase
      agreement with AIP.



AIP will continue to indemnify to the fullest extent permitted by law our
existing trust managers, officers and employees after the merger. Additionally,
we will continue the indemnification arrangements and trust managers' and
officers' liability insurance for our existing trust managers, officers and
employees after the merger. These obligations are guaranteed by DDR after the
merger.



THE SPECIAL MEETING (See page 23)


     The special meeting of our shareholders is scheduled to be held at 9:00
a.m., local time, on             , 2001, at 2200 Ross Avenue,           floor,
Dallas, Texas.


RECORD DATE; VOTING POWER (See page 23)



     Our board of trust managers has fixed the close of business on February   ,
2001 as the record date to determine holders of our shares entitled to notice of
and to vote at the special meeting.


                                        7
   14

     As of the record date, there were      shares issued and outstanding, held
by approximately           record holders. If you held common shares at the
close of business on the record date, you are entitled to one vote per share on
any matter that properly comes before the special meeting.


VOTES REQUIRED AND VOTING AGREEMENTS (See page 24)



     The approval of the merger and of the sale of properties requires the
affirmative vote of holders of 66 2/3% of our common shares outstanding on the
record date. DDR has agreed with us to vote in favor of the proposals. Five of
our shareholders, USAA Real Estate Company, Morgan Stanley Dean Witter
Investment Management Inc., on behalf of certain clients, MS Real Estate Special
Situations Inc., LaSalle Investment Management, Inc., on behalf of certain
clients, LaSalle Investment Management (Securities), LP, on behalf of certain
clients, and their affiliates, beneficially own or have the right to vote in the
aggregate, together with DDR, approximately 70.7% of the total common shares
outstanding on the record date. The five shareholders have entered into voting
agreements with DDR and Value Enhancement Fund to vote the shares they own or
over which they exercise voting control in favor of the proposals. The voting
agreements signed by the LaSalle entities provide that they may vote against the
proposals if they believe they must do so to satisfy their fiduciary duties to
their investment advisory clients. The LaSalle entities are entitled to vote
6.97% of our outstanding common shares on behalf of their clients. Our trust
managers and executive officers collectively held a total of approximately 0.7%
of the common shares outstanding on the record date.


SPECIAL COMMITTEE

     Our board of trust managers believed that eight of our trust managers,
Charles W. Wolcott, Albert T. Adams, Scott A. Wolstein, Robert H. Gidel, James
A. Schoff, Edward B. Kelly, Stanley J. Kraska, Jr. and T. Patrick Duncan had
actual or potential conflicts of interest in evaluating the transactions because
of their employment with us, their affiliation with DDR or their involvement in
litigation concerning a transaction involving AIP. Therefore, the board
appointed a special committee of three trust managers who did not have actual or
potential conflicts to review and evaluate the proposals. Two of the three trust
managers resigned from the special committee before it made its recommendation
to the board on the proposals and subsequently voted against the proposals.


FAIRNESS OF THE MERGER (See page 44)



     The special committee has received, and the board is entitled to rely upon,
the opinion dated November 1, 2000 of Chase Securities Inc., the financial
advisor to the special committee. The opinion states that, on that date, the
cash consideration to be received by the holders of our common shares in the
merger was fair from a financial point of view to those holders. Based on the
terms of the merger agreement on that date, the per share cash consideration to
be received by the holders of the common shares was not less than $13.74 per
share, less any dividends paid to maintain REIT status or to keep us from having
REIT taxable income for federal income tax purposes. DDR, DDR Sub and their
respective direct and indirect subsidiaries will not receive any of the merger
consideration. For its services, Chase Securities received retainer fees
totaling $500,000. If the merger is completed, Chase Securities will receive an
additional $2.0 million, subject to upward adjustment in an amount equal to 5%
of the consideration received by shareholders in excess of $14.50 per common
share, without deduction for transaction expenses. In addition, we have agreed
to reimburse Chase Securities for its reasonable expenses incurred in connection
with its services, including the fees and disbursements of its counsel, and we
have agreed to indemnify Chase Securities against various liabilities, including
liabilities arising under the federal securities laws. The full text of the
written opinion of Chase Securities is attached to this proxy statement as
Appendix A, and you should read it carefully. THE OPINION OF CHASE SECURITIES IS
DIRECTED TO THE SPECIAL COMMITTEE AND MAY BE RELIED UPON BY THE BOARD OF TRUST
MANAGERS AND IS NOT A RECOMMENDATION TO YOU AS TO HOW YOU SHOULD VOTE AT THE
SPECIAL MEETING.

OTHER TERMS OF THE MERGER AGREEMENT


     The merger agreement is attached to this proxy statement as Appendix B. You
should read the merger agreement. It is the legal document that governs the
merger.


  Conditions to the Merger (See page 63)


     The completion of the merger depends upon the satisfaction of a number of
conditions, including:


     1.  the approval of the merger by the holders of 66 2/3% of our outstanding
         common shares;



     2.  the absence of any order or legal restraint of any court or
         governmental entity preventing or prohibiting the merger; the closing
         of the sale of 31 properties to Value Enhancement Fund for net cash
         proceeds of not less than $135.4 million;



     3.  the continued accuracy of each party's representations and warranties
         and the fulfillment of each party's agreements contained in the merger
         agreement;



     4.  the absence of a material adverse effect, other than shareholder
         litigation, with respect to AIP which would give DDR the right to
         terminate the merger agreement;



     5.  the delivery by our legal counsel of a legal opinion on specified tax
         matters;



     6.  the holders of no more than 10% of our outstanding common shares shall
         have exercised dissenters' rights;

         than $34.2 million;



     8.  our transaction expenses not exceeding $13.738 million;



     9.  our net other assets being not less than $17.702 million; and



     10. our outstanding debt and available credit under our lines of credit
         being not more than $137.4 million.



     We satisfied the seventh condition regarding Manhattan Towers when that
property was sold in November 2000 for net proceeds of approximately $34.2
million. [We have satisfied the eighth condition because our transaction
expenses are $       . The ninth and tenth conditions have been satisfied
because our net other assets are $       , our outstanding debt under our lines
of credit is approximately $       and our available credit under our lines of
credit is approximately $       .] Other than the condition requiring
shareholder approval, which is an independent legal requirement, each party to
the merger may waive any condition that is intended for its benefit. If any of
AIP, DDR or DDR Sub elects to waive a condition and complete the merger, we will
evaluate the facts and circumstances giving rise to the waiver at that time. If
we determine that these facts and circumstances are material to shareholders, we
will disclose this information in a supplement to this proxy statement before
the special meeting and will resolicit your proxy.



  Termination (See page 65)


     Any party may terminate the merger agreement under a number of
circumstances, including the following:

     - mutual written consent of the parties;

     - any governmental entity has issued an injunction, order, decree or
       ruling, or taken any other action restraining, enjoining or otherwise
       prohibiting the merger that remains in effect on May 31, 2001;

     - the merger has not been completed by May 31, 2001, but this right to
       terminate the merger agreement will not be available to any party whose
       breach of the merger agreement has been the cause of or resulted in the
       failure to complete the merger by that date; or

     - we fail to get approval of the merger from the holders of at least
       66 2/3% of our common shares.

     In addition, DDR or DDR Sub, but not AIP, may terminate the merger
agreement under a number of circumstances, including the following
circumstances:

     - our board of trust managers has withdrawn or modified, in any manner
       which is adverse to DDR or DDR Sub, its recommendation or approval of the
       merger agreement;
                                        9
   16

     - our board of trust managers has recommended to our shareholders or
       approved an acquisition proposal from another party;

     - we have signed a definitive agreement regarding an acquisition proposal
       from a third party; or

     - we breach the merger agreement or fail to satisfy our closing conditions.

     AIP, but not DDR or DDR Sub, may terminate the merger agreement if prior to
the special meeting, our trust managers:

     - withdraw or modify their recommendation of the merger agreement; or

     - approve or recommend a superior acquisition proposal.

     We may also terminate the merger agreement if DDR or DDR Sub breaches the
agreement or they fail to satisfy their closing conditions.


  Termination Fees (See page 66)


     In the following circumstances, a party will be entitled to receive
termination fees:

     - We must pay DDR $4.5 million if the merger agreement is terminated for
       any of the following reasons:

          - breach of any representation, warranty, covenant, obligation or
            agreement by AIP such that the conditions to closing cannot be
            satisfied by May 31, 2001;

          - failure to close the sale to Value Enhancement Fund because of our
            breach of the property sale agreement;

          - if prior to the special meeting, the board withdraws its
            recommendation in favor of the merger;

          - if we enter into a definitive agreement with respect to an
            acquisition proposal; or

          - the board approves or recommends a superior acquisition proposal.

     - DDR must pay us $4.5 million if the merger agreement is terminated
       because DDR or DDR Sub breaches any representation, warranty, covenant,
       obligation or agreement, such that the conditions to closing cannot be
       satisfied by May 31, 2001. If the merger agreement is terminated because
       of a breach by DDR, DDR is responsible for the $3.0 million termination
       fee to be paid by us to Value Enhancement Fund. In all other cases, AIP
       would be responsible for any termination fee due to Value Enhancement
       Fund.


SALE OF PROPERTY PORTFOLIO (See page 76)



  General



     In connection with the merger, you are being asked to approve the sale of
31 of our properties to Value Enhancement Fund for $292.2 million. The purchase
price for the properties being acquired by Value Enhancement Fund resulted from
extensive negotiations between the special committee of the AIP board and its
financial advisor, Chase Securities, AIP's financial advisor, Salomon Smith
Barney Inc., management of AIP and representatives of Lend Lease, the fund
manager of Value Enhancement Fund, but did not rely on individual appraisals of
the specific properties. As the proceeds from the sale of the properties are
only one component of the overall merger consideration, the fairness of the
Value Enhancement Fund purchase price was evaluated by the special committee as
part of the overall merger consideration. For a discussion of the fairness of
the total merger consideration, please see the disclosure set forth under the
caption "Proposal One: The Merger; Special Factors -- Fairness of the Merger;
Opinion of Financial Advisor" on page   . The proceeds from the sale will be
used to help fund the cash payment for your shares in connection with the
merger. The property sale is conditioned upon the approval of the merger and
other customary conditions. The property sale agreement is attached to this
proxy statement as Appendix C. You should read the property sale agreement.



  Conditions to Closing



     The obligations of AIP and Value Enhancement Fund to close the sale of the
properties is subject to, among other things, the following conditions:



     - each of the party's representations and warranties contained in the sale
      agreement

                                       10
   17


      being true and correct in all material respects as of the closing date;



     - receipt of approval of the AIP shareholders for the sale; and



     - compliance with all of the covenants and obligations contained in the
      sale agreement.



  Termination Fee



     AIP will be obligated to pay Value Enhancement Fund a termination fee of
$3.0 million and reimburse it for actual out-of-pocket expenses not to exceed
$450,000 if any of the following occurs and AIP elects to or is required to
terminate the sale agreement:



     - AIP is unable to obtain approval for the sale from its shareholders;



     - AIP is unable to cause the contemporaneous closing of the merger;



     - AIP receives a superior acquisition proposal, as determined in good faith
      by its board of trust managers; or



     - the sale of the properties is not closed because the conditions to
      closing described above are not satisfied as a result of AIP's default.



TREATMENT OF SHARE OPTIONS AND DIVIDEND EQUIVALENT RIGHTS (See page 59)



     When the merger occurs, each outstanding option to purchase our common
shares will be canceled in exchange for cash equal to the difference between the
$     cash merger consideration and the then current exercise price per share of
that share option. DDR will not be paid for any of its 100,000 options. We will
pay an aggregate of $     to cash out all outstanding options.



     We have entered into mutual releases and settlement agreements with each of
our employees who holds dividend equivalent rights, commonly known as "DERs."
Under the terms of the agreements, each employee will receive an average of
$2.909 for each DER held. An aggregate of 460,000 DERs are outstanding. As a
result, we will pay an aggregate of $1,338,000 to cancel our DERs.



ACCOUNTING TREATMENT (See page 57)



     The merger is expected to be accounted for using the purchase method of
accounting in accordance with GAAP.



MATERIAL FEDERAL INCOME TAX CONSEQUENCES (See page 55)



     You will generally recognize gain or loss for federal income tax purposes
equal to the difference between the amount of cash you receive in the merger and
the adjusted basis of your shares. DUE TO THE INDIVIDUAL NATURE OF TAX
CONSEQUENCES, YOU ARE URGED TO CONSULT YOUR TAX ADVISOR AS TO THE SPECIFIC TAX
CONSEQUENCES TO YOU OF THE MERGER, INCLUDING THE EFFECTS OF STATE, LOCAL OR
OTHER TAX LAWS.



REGULATORY APPROVALS (See page 57)



     None of the parties is required to make filings with or obtain approvals
from regulatory authorities in connection with the merger, other than the filing
of articles of merger with Dallas County and the Secretary of State of the State
of Texas.



DISSENTERS' RIGHTS (See page 75)



     Under Texas law, you are entitled to dissenters' rights. Your rights and
the procedures you must follow in order to validly exercise those rights are
described on page 75.



LITIGATION RELATING TO THE MERGER (See page 58)



     Since the announcement of the proposed transactions, DDR, AIP and the trust
managers have been named as defendants in three purported shareholder class
action and derivative lawsuits seeking, among other things, to enjoin the
proposed merger. The complaints allege breach of fiduciary duties, abuse of
control of AIP, waste and unjust enrichment in connection with the proposed
merger. DDR, AIP and the trust managers deny the allegations and intend to
vigorously defend themselves.

*Includes the special distribution of $1.27 per share paid on January 17, 2001
 to shareholders of record on December 29, 2000.



     For the year ended December 31, 2000, we paid distributions totaling $2.15
per common share, which includes the special distribution of $1.27 per share.



     Under the merger agreement, we may authorize, declare and pay dividends
only in the minimum amount necessary to avoid jeopardizing our status as a REIT
under the Internal Revenue Code and to avoid having positive REIT taxable income
for federal income tax purposes. The merger agreement provides that any
dividends paid for these purposes will reduce the amount of merger
consideration. The special distribution made to avoid having REIT taxable income
for fiscal 2000 as a result of the sale of our Manhattan Towers property reduced
the merger consideration by $1.27 per share. We may also pay a dividend based on
cash generated by operations if there is a delay between the scheduled closing
date and the closing. Any dividend paid for that reason would not reduce the
amount of merger consideration.


     If the merger is not consummated, our future distributions will be at the
discretion of our board of trust managers and will depend upon numerous factors,
including gross revenues received from properties, operating expenses, capital
expenditures for properties and interest expense incurred in borrowing. Pursuant
to Internal Revenue Code provisions, a REIT is generally required to distribute
at least 95% of its REIT

                                       12
   19

taxable income. Recently enacted legislation reduces the REIT distribution
requirement to 90% for taxable years beginning after December 31, 2000.

     Distributions to the extent of our current and accumulated earnings and
profits for federal income tax purposes generally will be taxable to
shareholders as ordinary dividend income, ordinary gain or capital gain.

     Distributions in excess of earnings and profits generally will be treated
as a non-taxable reduction of the shareholder's basis in the common shares to
the extent thereof, which may have the effect of deferring taxation until the
sale of the shares, and thereafter as taxable gain. Following is an allocation
of our 2000 distributions to shareholders:

operating properties to Value Enhancement Fund for $292.2 million and the
related debt payoff of $156.2 million and repurchase of 9,892,140 shares for

     The following pro forma condensed consolidated statement of operations of
AIP for the year ended December 31, 1999 has been prepared as if each of the

and liabilities of the properties are adjusted to fair value.



     Such pro forma financial information is based in part upon (i) the

- ---------------


(a)The Board of Governors of the National Association of Real Estate Investment
   Trusts ("NAREIT") defines funds from operations ("FFO") as net income (loss)
   computed in accordance with GAAP, excluding gains or losses from debt
   restructuring and sales of property, plus real estate related depreciation
   and amortization, and after adjustments for unconsolidated partnerships and
   joint ventures. In addition, NAREIT recommends that extraordinary items not
   be considered in arriving at FFO. We calculate FFO in a manner consistent
   with the NAREIT definition. We believe FFO is an appropriate measure of our
   performance relative to other REITs. FFO provides investors with an
   understanding of our ability to incur and service debt and make capital
   expenditures. There can be no assurance that FFO presented by AIP is
   comparable to similarly titled measures of other REITs. While other REITs may
   not always use a similar definition, this information does add comparability
   to those which have adopted the NAREIT definition. FFO should not be
   considered as an alternative to net income or other measurements under GAAP
   as an indicator of our operating performance or to cash flows from operating,
   investing, or financing activities as a measure of liquidity. FFO does not
   reflect working capital changes, cash expenditures for capital improvements,
   or principal payments on indebtedness.

statement and the proxies solicited by this document. In addition to the use of
the mails, proxies may be solicited by our officers and trust managers and
regular employees, without additional remuneration, by personal interviews,
written communications, telephone, telegraph or facsimile transmission. We also
will request brokerage firms, nominees, custodians and fiduciaries to forward
proxy materials to the beneficial owners of common shares held of record by
these brokerage firms, nominees, custodians and fiduciaries and will provide
reimbursement for the cost of forwarding the materials in accordance with
customary charges.

RECORD DATE AND QUORUM REQUIREMENT


     The record date for the special meeting has been fixed as the close of
business on February   , 2001. Holders of our common shares are invited to
attend the special meeting. Only holders of our common shares on the record date
may vote at the special meeting and they will have one vote per share on matters
properly presented at the special meeting.



     On the record date, there were           common shares outstanding, which
were held by approximately           record holders. As of the record date, our
trust managers and executive officers and their affiliates were entitled to vote
          common shares, representing approximately      % of the total common
shares then outstanding. Our trust managers (other than Messrs. Bricker and
Giles) and our executive officers have advised us that they intend to vote their
shares in favor of the transactions. Messrs. Bricker and Giles have notified us
that they intend to vote against the transactions. Mr. Bricker previously
advised the board that in his capacity as a trust manager he voted against the
proposed transactions and in his capacity as a shareholder he intends to vote
against the transactions because he opposes the transaction with Value
Enhancement Fund because of the price. Mr. Giles previously advised the board
that in his capacity as a trust manager he voted against the proposed
transactions and in his capacity as a shareholder he intends to vote against the
transactions because he believes real estate is in a down market and that we
should wait to sell until the market improves. Consequently, he believes that
the shareholders will receive inadequate consideration. Both Messrs. Bricker and
Giles declined to make a recommendation to shareholders as to how they should
vote their shares.


     A list of shareholders will be available for examination by holders of our
common shares for any purpose related to the special meeting, during the 10-day
period preceding the special meeting, at our offices, 6210 N. Beltline Road,
Suite 170, Irving, Texas 75063.

                                       23

     The presence at the special meeting, either in person or by proxy, of the
holders of a majority of the outstanding common shares entitled to vote will
constitute a quorum for the transaction of business by the holders of common
shares at the special meeting.

     Common shares present in person or represented by proxy, including shares
whose holders abstain or do not vote with respect to one or more of the matters
presented for shareholder approval, will be counted for purposes of determining
whether a quorum exists at the special meeting.

REQUIRED VOTE


     The vote of the holders of 66 2/3% of our common shares outstanding on the
record date is the only vote required to approve each of the proposals. Each of
the Morgan Stanley Dean Witter entities, USAA Realco and the LaSalle entities
have signed agreements with each of Value Enhancement Fund and DDR, and DDR has
agreed with us, to vote the common shares over which each has beneficial
ownership or voting control, representing in the aggregate approximately 70.7%
of the total common shares outstanding on the record date, in favor of the
proposals. If these shareholders vote in accordance with their voting
agreements, the proposals will be approved. The LaSalle entities, which vote
6.97% of our outstanding shares, have the right to vote against the proposals if
they believe they should do so to satisfy their fiduciary duties to their
investment advisory clients. Approval of at least a majority of the non-DDR
shareholders is not required to complete the merger.


VOTING PROCEDURES

     Common shareholders who attend the special meeting may vote by ballot.
However, we know that many of you may not be able to attend the special meeting.
Accordingly, our board of trust managers is soliciting proxies so that each
holder of common shares on the record date has the opportunity to vote on the
sale of properties, the merger and any other proposal to be considered at the
special meeting. When a proxy card is returned properly signed and dated, the
shares represented by the proxy card will be voted in accordance with the
instructions on the proxy card. If you do not return a signed proxy card or vote
your common shares at the special meeting, your common shares will not be voted
and thus will have the effect of a vote against the transactions. A properly
executed proxy marked "Abstain" will not be voted. Since the affirmative vote of
66 2/3% of the common shares outstanding and entitled to vote at the special
meeting is required to approve the transactions, a proxy marked "Abstain" will
have the effect of a vote against the transactions. Abstentions occur when a
shareholders affirmatively elects to abstain from voting on the matter at issue
by so marking his or her proxy card.

     Except for routine and non-controversial matters, the rules of the New York
Stock Exchange do not permit brokers and nominees to vote the shares that they
hold for customers either for or against a proposal without specific
instructions from the person who beneficially owns those shares. The votes not
permitted to be cast on non-routine matters are called "broker non-votes."
Broker non-votes will be treated as shares that are present for the purpose of
determining the presence of a quorum. However, for the purposes of determining
the outcome of any matter as to which the broker or nominee has indicated on the
proxy that it does not have discretionary authority to vote, those shares will
be treated as not entitled to vote with respect to that matter. The merger and
the sale of the properties are not considered routine and non-controversial
matters for this purpose. Therefore, if your common shares are held by a broker
or other nominee and you do not give your broker or nominee instructions on how
to vote your shares on the transactions, this will have the same effect as
voting against the transactions.

     You are urged to mark the box on the proxy card to indicate how your common
shares are to be voted. If you return a signed proxy card, but do not indicate
how your shares are to be voted, the common shares represented by the proxy card
will be voted "FOR" the merger and the sale of the properties. The proxy card
also confers discretionary authority on the individuals named on the proxy card
to vote the shares represented by the proxy card on any other matter that is
properly presented for action at the special meeting.

                                       24
   31

     You may revoke an executed and returned proxy card at any time before it is
voted by:

     - notifying in writing our corporate secretary prior to the vote at the
       special meeting, at American Industrial Properties REIT, 6210 N. Beltline
       Road, Suite 170, Irving, Texas 75063;

     - granting a subsequent proxy; or

     - appearing in person and voting at the special meeting. Attendance without
       voting at the special meeting will not in and of itself constitute
       revocation of a proxy.

OTHER MATTERS TO BE CONSIDERED

     We are not aware of any business or matter other than the proposals to
approve the merger and the sale of 31 of our properties. If, however, any other
matter properly comes before the special meeting, the proxy holders will vote on
these matters in their discretion.


                   PROPOSAL ONE: THE MERGER; SPECIAL FACTORS


GENERAL DESCRIPTION


     At the time the merger becomes effective, DDR Sub will be merged with and
into AIP. We will be the surviving entity in the merger and AIP will be governed
by our current declaration of trust and bylaws. As a result of the merger, our
common shareholders, other than DDR, DDR Sub and their respective direct and
indirect subsidiaries, will receive $          in cash, without interest, for
each common share they hold. DDR will be our sole shareholder, thereby
controlling our remaining 39 properties. If AIP sells all or substantially all
of its properties remaining after the sale to Value Enhancement Fund within six
months after the effective date of the merger, and if the sale price exceeds
values determined prior to the merger by AIP and DDR, you will receive
additional merger consideration. The additional consideration per share will be
calculated by subtracting the agreed value from the sale price and dividing the
result by the total number of common shares outstanding on the closing date of
the merger, including shares held by DDR and its affiliated entities. DDR's
current plans are to operate the remaining AIP properties acquired in the merger
and to implement an orderly disposition plan. DDR is exploring the possible sale
of the properties at acceptable prices (both as a group and as individual
assets) and has responded to unsolicited inquiries regarding certain of the AIP
properties. At this time, DDR does not have any agreement and has not entered
into any letter of intent to sell any of the AIP properties.


BACKGROUND OF THE MERGER


     Since our formation, our fundamental business objective has been to
maximize shareholder value by maintaining long-term growth in funds from
operations for distribution to shareholders. To achieve this objective, we
commenced our operations with an emphasis on the acquisition and operation of
light industrial/office flex properties. More recently, we have focused on
maximizing the internal growth of our portfolio through internalizing property
management and accounting. The term "flex properties" generally refers to single
story buildings that have loading doors in the rear of the building and can be
flexibly configured to meet specific needs of tenants including office,
warehouse, showroom, research and development, and light assembly areas.



     Beginning in early 1998 and continuing into 1999, market prices for
publicly traded REITs experienced significant declines. During this period,
there were relatively few real estate offerings in the public equity markets and
the liquidity of the real estate debt markets had tightened. As a result, we
were constrained from obtaining financing through the public equity or debt
markets. The only equity financing available to us was through sales of our
common and/or preferred shares to DDR under the July 1998 share purchase
agreement. For a discussion of that agreement, see "-- Transactions and
Relationships Between AIP and DDR" on page 53. Because of these developments, we
were limited in our ability to achieve our business objective of increasing
funds from operations through strategic acquisitions.


                                       25
   32


     In early 1999, our board of trust managers held several meetings to
discuss, among other things, the performance of and growth opportunities for
AIP. The trust managers also evaluated our business plan and discussed our share
price and the need to increase shareholder value, and how to promote analyst
coverage of our company. These discussions led to the determination in May 1999
that we should retain the services of Salomon Smith Barney Inc. as financial
advisor to assist us in our review of strategic alternatives, including a sale
of AIP, a strategic merger with a complementary real estate entity, selected
asset sales, liquidation of AIP and continuation of AIP's strategy.



     From mid-May through August 1999, our board of trust managers held several
meetings to discuss, and were updated periodically as to, the progress of AIP's
strategic alternative review.


     During this period, our trust managers created a committee of the board
consisting of Messrs. Wolcott, Wolstein, Gidel, Bricker and Morris to
investigate the different strategic alternatives.


     On August 4, 1999, the trust managers held their quarterly meeting. At this
meeting, the trust managers directed Salomon Smith Barney to begin contacting
select potential buyers in order to explore the interest of these parties in a
possible transaction with AIP and the valuation levels that could be obtained in
a transaction as part of AIP's strategic alternative review.


     Following this meeting, our board of trust managers and management, with
the assistance of Salomon Smith Barney, identified potential buyers based upon
several criteria, including: (1) parties that owned or had invested in flex
properties; (2) parties that had real estate portfolios located in geographic
regions where AIP's properties are located; or (3) parties that were well known
institutional real estate investors (including opportunity funds and pension
funds) to which AIP's growth characteristics and size might be attractive. The
initial list included 50 potential buyers comprised of 16 public companies, 19
opportunity funds and 15 pension fund advisors. As the process continued, the
list expanded to include an additional 10 buyers as a result of outside
inquiries.


     In mid-September 1999, a process was undertaken to elicit offers from
interested parties for the company or all or a significant portion of our
assets. Some parties which expressed interest in only specific assets were
encouraged to submit bids for only such assets even though our preference
remained that if the decision was made to sell our assets, we would like to sell
all of our assets in a single transaction. In total, confidentiality agreements
were ultimately sent to 60 potential buyers which had indicated interest in a
possible transaction with AIP.


     On September, 10, 1999, the trust managers reestablished the board
committee for purposes of evaluating strategic alternatives available to AIP.
The committee membership was changed to reduce the size of the committee and to
have broader institutional representation on the committee. Messrs. Wolstein,
Bricker, Duncan and Morris were appointed as the members of the committee. The
committee was empowered to evaluate the strategic alternatives available to AIP
and to make a recommendation to the full board.


     In the initial round of bids, two privately-held companies submitted
preliminary indications of interest for the entire company, subject to due
diligence, of $14.00 and $12.50 to $14.25 per share (gross valuation before
transaction costs), respectively. Additionally, Lend Lease orally indicated a
total asset valuation, subject to due diligence, of approximately $625 million,
or $13.35 per share on a gross valuation basis without deduction for transaction
expenses. Lend Lease is an institutional real estate advisor that advises, among
other clients, Value Enhancement Fund. Value Enhancement Fund is a private
investment fund. Another institutional investor indicated that it was evaluating
making a joint proposal for the industrial portion of our assets with a public
company as its partner at a valuation of approximately $350 million. Four other
bidders submitted indications of interest for portions of the Company's
portfolio ranging from one asset for $3 million to 14 assets for $140 million.



     On November 3, 1999, our board of trust managers convened its regular
quarterly meeting. Salomon Smith Barney and AIP's legal counsel also attended
the meeting. Mr. Wolcott disclosed to the board that he had been contacted by
representatives of one of the bidders, referred to as "bidder A," regarding the
possibility of management participating in a possible bid for AIP or its assets.
Mr. Wolcott stated that he

                                       26
   33


had informed bidder A that he would have to notify the committee of management's
potential participation and discuss it with the board before engaging in any
discussions. Mr. Wolcott confirmed that he had not seen, nor had he participated
in, the preparation of bidder A's written bid. Salomon Smith Barney stated that
the written bid from bidder A did not reference any agreement with management or
any condition to its bid of management's participation. A discussion followed as
to the nature of management's participation in any of the bids and the process
for evaluating the strategic alternatives available to AIP. AIP's legal and
financial advisors were directed to exclude management from any discussions with
bidders while bidder A continued to be a potential bidder with involvement by
AIP management.



     On November 15, 1999, our trust managers met with legal counsel to AIP and
Salomon Smith Barney to discuss the composition and the formation of a special
committee of trust managers in connection with AIP's review of strategic
alternatives and to receive an update on the status of the bid process. Mr.
Wolcott then updated the board as to the status of management's potential
participation with bidder A. Mr. Wolcott stated that management had not reached
an agreement with bidder A but that negotiations were ongoing. Salomon Smith
Barney then proceeded to update the board on the status of the bid process.
Following a discussion of the potential conflicts of interest, the board then
formed a special committee consisting of three disinterested trust managers,
Messrs. Bricker, Giles and Morris, and authorized the special committee to
review, evaluate and make a determination with respect to acquisition proposals
and report their conclusions to the board.



     On November 20, 1999, the newly formed special committee held its
organizational meeting, elected Mr. Bricker as chairman, established a tentative
schedule and agenda for its meetings and selected Salomon Smith Barney and
Thompson & Knight L.L.P. to serve as independent financial advisors and
independent counsel, respectively, to the committee. The committee then reviewed
with Salomon Smith Barney strategic alternatives and the status of various
indications of interest for AIP. The committee discussed in detail the interests
of members of our board of trust managers in connection with acquisition
proposals. At this meeting, counsel for AIP reviewed the basic form of
acquisition documents to be submitted to prospective bidders and counsel for the
special committee reviewed the role of special committees and the duties and
responsibilities of the special committee to AIP and the holders of its common
shares.



     From November 1999 through October 2000, the special committee held 38
meetings. There was unanimous attendance at the meetings, except that Mr. Giles
did not attend the meetings on April 24 and May 24, 2000 and one of the meetings
on May 26, 2000. Messrs. Bricker and Giles resigned from the special committee
in August 2000. Except as otherwise described below, the only attendees at these
meetings were the special committee members and the committee's advisors.
Negotiations with respect to the specific terms of the various bids described
below were generally undertaken on the special committee's behalf, and at the
special committee's direction, by Salomon Smith Barney, and the special
committee's legal and financial advisors.



     On November 22, 1999, the special committee met and reviewed with Salomon
Smith Barney the status of discussions and negotiations with prospective bidders
and the status of their due diligence and data room reviews.



     On November 24, 1999, we issued a press release disclosing our exploration
of strategic alternatives. Management of AIP notified Mr. Wolstein that members
of the management group were no longer participating with bidder A in a joint
acquisition proposal for AIP and consequently management would be available to
participate in discussions with bidder A and other bidders.


     On December 6, 1999, our special committee and the other trust managers met
for a transaction update and to discuss revised indications of interest that had
been submitted by those third party bidders that continued to express an
interest in a possible transaction with AIP. Lend Lease had submitted a final
written indication of interest for the entire company at a price of $13.58 per
share (net of assumed transaction costs of $9.9 million). Bidder A had submitted
a final written indication of interest for the entire company at a price of
$13.00 per share (net of unspecified transaction costs), assuming
                                       27
   34

consummation of various property sales and the conversion of AIP equity
interests into mezzanine financing. The institutional investor that had offered
$13.00 to $13.50 in its initial indication, indicated that it had not finalized
due diligence sufficiently to confirm that its final offer would be in this
range. The other privately-held bidder provided a verbal indication of $10.40 to
$11.00 (net of unspecified transaction costs), but did not submit a written
indication. At this meeting, the special committee directed Salomon Smith Barney
to decline the verbal offer from one of the privately-held bidders, and confirm
the bids of bidder A and Lend Lease while waiting for the institutional
investor's final indication. The special committee also directed Salomon Smith
Barney, among other things, to obtain individual asset bids for properties that
may be able to be sold separately.

     On December 10, 1999, the institutional investor indicated that, based upon
extensive work performed over the past 10 days, it could not confirm its
preliminary bid range. This bidder indicated its revised bid would be in the
upper $12.00 range and, therefore, it would not be submitting a firm bid.


     On December 13, 1999, the special committee met with Salomon Smith Barney,
the special committee's legal advisors and AIP's legal advisors and was updated
regarding bid submissions and potential bid submissions by third parties. At
this meeting, the special committee also discussed with its advisors other
strategic alternatives, including the sale of AIP, a continuation or
modification of the current business strategy and liquidation of AIP.



     On December 13, 1999, our board of trust managers met to review the status
of AIP's strategic alternatives. At this meeting, the trust managers reviewed
with Salomon Smith Barney then current REIT market conditions, the bids received
and alternatives to be considered by the board, including completing the current
sale process, continuing as a public company or liquidating assets. In assessing
strategic alternatives, the special committee considered a number of challenges
then facing AIP, including limited liquidity for existing shareholders, limited
access to cost-effective equity capital, high leverage based on debt to market
capitalization and the inability to create a long-term sustainable growth rate.
The committee decided to continue the then current sale process and its review
of other strategic alternatives.


     After this meeting, the special committee instructed Salomon Smith Barney
to notify Lend Lease and bidder A that their bids were too low, and to attempt
to seek a higher value from these parties.

     Bidder A indicated that it was unable to raise its bid. Lend Lease
indicated that it might be able to bid a higher value for a significant portion
of our assets if it were not required to bid for the entire company. Lend Lease
was encouraged to re-bid on this basis.

     On December 17, 1999, Lend Lease submitted a bid to acquire 35 of our
properties for $361 million.


     On December 23, 1999, the special committee met with Salomon Smith Barney,
the special committee's legal advisors and AIP's legal advisors to discuss and
review, among other things, the revised offer submitted by Lend Lease and a
revised business strategy for AIP prepared by management. At this meeting, the
special committee was informed by Salomon Smith Barney that DDR had indicated an
interest in a two-step transaction in which some of AIP's assets would be sold
to Lend Lease and AIP would then merge with DDR. The special committee
authorized Salomon Smith Barney to discuss with DDR and Lend Lease possible
offers for AIP on that basis.



     On January 13, 2000, Lend Lease and DDR, along with Salomon Smith Barney
and Chadwick Saylor, DDR's financial advisors, met to discuss possible
proposals. At this meeting, DDR and Lend Lease discussed allocating assets among
collateral pools in order to minimize debt prepayment penalties. DDR also
encouraged Lend Lease to bid on more assets.



     On January 26, 2000, our board was updated by Salomon Smith Barney as to
potential proposals from Lend Lease and DDR. At this meeting, Salomon Smith
Barney indicated that it had discussed and reviewed with Lend Lease and AIP's
management team a portfolio of 41 assets that Lend Lease was evaluating in
contemplation of a bid. Additionally, Salomon Smith Barney reported that bidder
A had reiterated its interest in pursuing a transaction with AIP for $13.25 (net
of unspecified transaction costs) per share to AIP shareholders.


                                       28
   35

     On February 1, 2000, Lend Lease submitted a revised bid for 38 of our
properties for $365 million. Subsequently, Lend Lease removed six properties and
bid $322.4 million for 32 of our properties.

     On February 8, 2000, Chadwick Saylor, DDR's financial advisor, notified
Lend Lease that DDR could not propose a transaction to AIP unless Lend Lease's
portfolio acquisition created more value to us.

     On February 14, 2000, Lend Lease orally communicated to DDR and Salomon
Smith Barney a revised offer of $330 million for the same 32 assets. Lend Lease
emphasized that this offer was its final offer and, if it was not accepted in a
timely manner, Lend Lease would pursue other opportunities.

     Based on the revised Lend Lease offer, DDR orally indicated to the special
committee that, in order to facilitate a transaction, it would consider
acquiring all our remaining real estate assets in a merger transaction.

     During January and early February, several calls were received from bidder
A reiterating its interest in pursuing a transaction for our entire company.
Bidder A submitted a revised bid on February 7, 2000 reflecting a valuation of
approximately $13.30 (net of unspecified transaction costs) per AIP common
share.


     On February 18, 2000, the special committee met with Salomon Smith Barney,
the special committee's legal advisors and AIP's legal advisors and was updated
as to the communications and developments that had occurred with respect to
proposals to acquire all of AIP since its last meeting, including a revised
indication of interest from bidder A that placed a valuation for us at $13.35
(net of unspecified transaction costs) per common share. The special committee
was informed that the bidder A proposal contemplated an offer of $11.55 in cash
per share and $1.80 in proceeds from the sale of certain of our properties prior
to consummation of the transaction with bidder A. It was noted that the bidder A
proposal required conversion of equity interests in AIP and contemplated
mezzanine financing and material conditions to consummation of the proposal. At
this meeting, the special committee was also informed that negotiations with
Lend Lease resulted in an offer of $330 million for 32 of our properties and
that Lend Lease had indicated that the offer was final. DDR indicated that it
would consider acquiring all of the remaining assets and assuming all remaining
liabilities in a merger transaction. Based on AIP management's estimates of the
transaction costs, the DDR and Lend Lease proposals indicated a value of $14.21
per AIP common share before transaction costs and $13.59 after transaction costs
estimated to be approximately $13.0 million. The special committee reviewed the
basic terms and conditions of bidder A's proposal and concluded that the revised
offer was inadequate as compared to the combined Lend Lease and DDR proposals.
The special committee directed Salomon Smith Barney to continue negotiations
with Lend Lease and DDR to increase the per share price to non-DDR shareholders
in the event that the proposed acquisitions were consummated.



     The special committee met on February 22, 2000 and February 23, 2000 to
discuss the Lend Lease and DDR proposals. The special committee also discussed
DDR's existing share purchase obligations under its share purchase agreement
with AIP, and our acquisition of properties previously owned by an affiliate of
DDR. The special committee also discussed various alternatives to increase the
proposed bid price for our common shares and established its strategy for the
conduct of further negotiations with DDR. The special committee was informed by
Salomon Smith Barney that DDR had indicated that it was reluctant to guarantee a
firm price to non-DDR shareholders because DDR's due diligence was incomplete.
The special committee concluded that it would be advisable and in the best
interests of AIP and its shareholders to encourage further negotiations with
Lend Lease and DDR, and in order to further such negotiations, the special
committee authorized AIP to enter into exclusivity agreements with Lend Lease
and DDR for a period of two weeks. At this meeting, the special committee
reviewed the estimated transaction costs, including investment banking fees,
legal, accounting and other fees, debt prepayment and assumption fees and
severance payments under existing employment contracts. At that time,
transaction costs were estimated by the special committee to be $12.9 million.
The special committee discussed the ways of possibly reducing the amount of such
costs in order to increase the net price to AIP shareholders, including
negotiating the amount of severance payments to management and the fees payable
to AIP's financial advisors.

     On February 23, 2000, the board of trust managers held a regular quarterly
meeting. The special committee stated that additional time would be required to
complete its evaluation of strategic alternatives and review and consideration
of various acquisition proposals submitted by third parties. The special
committee recommended that exclusivity agreements be executed with each of DDR
and Lend Lease that would restrict us from negotiating with other parties from
February 28, 2000 through March 13, 2000 to provide the parties additional time
to complete their respective due diligence review of us and our assets. After
discussion, our trust managers agreed to provide these exclusivity agreements.


     On February 25, 2000, the special committee met and discussed the estimated
transaction costs, including the amount of anticipated severance and other
payments to management of AIP, in connection with the consummation of the Lend
Lease and DDR proposals.



     On March 15, 2000, each of DDR and Lend Lease submitted bids to the special
committee.



     On March 22, 2000, the special committee met with Salomon Smith Barney and
the special committee's legal advisors and was updated as to discussions,
negotiations and developments since the special committee's last meeting. The
special committee was advised that DDR and Lend Lease had submitted preliminary
bids resulting in a gross price range before transaction costs of $13.39 to
$13.62 per AIP common share, with a net cash price range to non-DDR shareholders
of $13.09 to $13.32 after approximately $6.0 million of estimated transaction
costs, as calculated by DDR. The special committee questioned DDR's calculation
of transaction costs and reiterated its desire to increase the net price to our
shareholders from the proposed range through further negotiations with Lend
Lease and DDR. After further discussions, the special committee rejected the DDR
and Lend Lease offers and instructed Salomon Smith Barney to relay the special
committee's views to DDR and Lend Lease.



     Later on March 22, 2000, Mr. Bricker and the special committee's legal
advisors held a telephonic meeting with Mr. Wolstein and other representatives
of DDR to negotiate a higher price on behalf of AIP and to seek a fixed price
rather than one based on a formula as set forth in the DDR bid. The meeting was
called by Mr. Bricker to clarify the special committee's position with respect
to key provisions in DDR's bid.



     On March 31, 2000, the special committee met and reviewed a draft proposal
dated March 24, 2000 from DDR setting forth a proposed price to non-DDR holders
of AIP common shares of $13.85 per AIP common share before transaction costs.
Another alternative, under which the proceeds from the proposed sale of assets
to Lend Lease could be used to repurchase AIP common shares from DDR and other
major shareholders, was also discussed. The chairman noted that, at his request,
management had prepared and distributed to members of the special committee a
written summary of this buy-out proposal, which indicated a price per share to
selling shareholders less than the anticipated net price upon consummation of
the Lend Lease and DDR transactions and the down-sizing of AIP to an
unacceptable level as a going concern. The special committee discussed the
summary of the buy-out assumptions. The special committee also reviewed and
discussed the estimate of transaction costs prepared by management. The special
committee noted that, based on management's estimates of the transaction costs
associated with the Lend Lease and DDR transactions, the net price to non-DDR
shareholders following confirmation of the transactions would be in the range of
$13.04 to $13.24 per AIP common share, reflecting estimated transaction costs of
$13.0-$18.0 million, as calculated by management. The special committee
discussed the viability of redeeming DDR's and other major shareholders' share
positions and the comparison of that transaction with the proposed DDR and Lend
Lease bids for AIP. At this meeting, the special committee also discussed the
possible retention of a separate financial advisor for the special committee to
advance negotiations with DDR and Lend Lease.


     On April 4, 2000, the special committee met to consider and take action
upon the pending bids of Lend Lease and DDR at a resulting gross valuation cash
price of $13.85 per AIP common share to the non-DDR shareholders, reflecting a
net price to non-DDR shareholders in the range of approximately $13.04 to $13.27
per AIP common share. The committee reviewed and summarized the discussions and
negotiations since the bid proposals were first presented to the committee in
December 1999. Mr. Bricker, the chairman of the special committee, summarized
the alternatives available to AIP, including accepting
                                       30
   37

or rejecting the acquisition proposals of DDR and Lend Lease, rejecting the DDR
proposal and consummating the sale of assets to Lend Lease followed by the
liquidation of AIP or the use of the proceeds to repurchase AIP common shares,
and continuation as an independent company with a revised business plan. Mr.
Wolcott joined the meeting and responded to questions from members of the
committee regarding the net asset valuation prepared by management. Following
this discussion, the committee voted two to one (with Mr. Morris voting against)
to reject the latest DDR and Lend Lease proposals.


     On April 7, 2000, the special committee met telephonically and Mr. Bricker
reviewed the status of the pending negotiations with Lend Lease and DDR,
including the revised bid dated April 5, 2000 from DDR proposing an increase in
price for the remaining assets of AIP, following the sale of assets to Lend
Lease, resulting in an aggregate value for AIP of $14.00 per AIP common share on
a gross basis and $13.70, net of estimated transaction costs of approximately
$6.0 million, as calculated by DDR. The special committee again disputed DDR's
calculation of estimated transaction costs and the expected net price per AIP
common share. After a full discussion, the special committee was unable to reach
a conclusion regarding the revised proposal. During the discussion, the special
committee authorized AIP management to continue direct negotiations with Lend
Lease regarding the proposed sale of assets. Chase Securities, the financial
advisor being considered by the special committee, joined the conference call
and was briefed on the current status of the negotiations. Chase Securities
detailed its qualifications, experience and independence and discussed the scope
of the proposed assignment and fee arrangements.


     On April 13, 2000, AIP asked Lend Lease if it would remove from its bid the
Manhattan Towers asset. In addition, AIP asked Lend Lease to reevaluate its
decision not to purchase five assets that were part of the portfolio on which
DDR had bid. Lend Lease also agreed to reconsider those five properties.

     On April 19, 2000, pursuant to its discussions with management, Lend Lease
submitted a revised bid that excluded the Manhattan Towers asset. The revised
bid amount of $288.7 million was $44 million lower than its previous bid, which
had included Manhattan Towers. Lend Lease informed AIP that it would not bid on
the five properties it was asked to reevaluate.

     On April 24, 2000, the special committee met to discuss Chase Securities'
proposed activities relating to developing transaction valuations, developing
alternatives to the separate pending proposals of Lend Lease and DDR, and
initiating direct negotiations with DDR and Lend Lease. Chase Securities was
then formally engaged to serve as the special committee's financial advisor.

     On April 25, 2000, the board of trust managers met to discuss the status
and process of the deliberations. Our board of trust managers agreed that the
negotiation of a potential Lend Lease transaction should be given priority
pending the review of any other strategic alternatives.


     On May 2, 2000, the special committee met and Chase Securities made a
detailed presentation regarding its activities since its retention by the
committee. The presentation included analyses of all offers, a preliminary real
estate analysis, a review of the DDR July 1998 share purchase agreement, trading
characteristics of AIP, and a review of strategic alternatives available to AIP
in light of the current market situation, including merger/sale transactions,
liquidation, or a stand alone transaction with DDR. Chase Securities also
reviewed the discussions it had with Lend Lease and DDR. In reviewing the
strategic alternatives, a number of considerations were discussed including
limited liquidity for AIP shares, significant overhang represented by large
institutional investors, lack of third party research coverage, and transaction
costs associated with any transaction, among other discussion items. Chase
Securities also provided an outline of the next steps and considerations to be
undertaken, including finalizing a strategic alternative review and formulating
final and thorough responsive proposals to DDR and Lend Lease. After a full
discussion, the committee unanimously concluded that it could support a minimum
net price of $13.50 per AIP common share. The committee requested that Chase
Securities meet with representatives of DDR to discuss the transaction
valuations and minimum price per share. In deciding to pursue the pending sale
and merger transactions, the committee found that the proposed merger would
result in a higher present value for shareholders of AIP than pursuing any of
the other strategic alternatives.

     On May 3, 2000, our board of trust managers held its regular quarterly
meeting. The special committee reported, based upon the advice of Chase
Securities, that it was recommending that AIP proceed in negotiations with Lend
Lease on the sale of a significant portfolio of assets and with DDR on a
proposed merger of AIP into DDR simultaneously with the sale to Lend Lease and
with the sale of Manhattan Towers as a standalone transaction. In addition, the
chairman of the special committee, Mr. Bricker, had a telephonic discussion with
representatives from Lend Lease expressing the special committee's desire to
move forward with a transaction and the execution of a term sheet.


     On May 11, 2000, the special committee met to discuss definitive term
sheets for the pending bids of Lend Lease and DDR to acquire AIP and the
analysis of the proposed transactions prepared by management. In particular, the
committee reviewed a summary of the provisions of the Lend Lease term sheet,
including the purchase price of $288.7 million in cash and debt assumption, the
earnest money deposit, the conditions to closing, the description of properties
and the required documentation, and the provisions of the DDR term sheet,
including the structure of the proposed transaction, the merger consideration,
the possible subsequent sale of properties by DDR, the closing, the conditions
to closing, indemnity, voting arrangements and termination and break-up fees.
The analysis indicated a net price of $13.50 per AIP common share if the
proposed transactions were consummated on the assumptions outlined. The
committee also reviewed summaries of prior discussions between members of the
committee and other third parties to acquire specific assets of AIP. At this
meeting, the special committee received a report from the transaction costs
committee, a separate committee of trust managers appointed by the board to
review and negotiate transaction costs in connection with the Lend Lease and DDR
proposals, including executive compensation payments, investment banking fees
and legal fees. The transaction costs committee reported that it was seeking to
reduce payments for dividend equivalent rights by approximately $1.24 million
pursuant to a proposed compromise with management.



     The special committee met on May 24, 2000 and twice on May 26, 2000 to
discuss the status of the negotiations with Lend Lease. The committee outlined
its position with respect to several material terms contained in the Lend Lease
term sheet, including the purchase price for the properties, the required
minimum debt assumption of $118.0 million, the payment of costs associated with
the transaction, the escrow of $3.0 million by Lend Lease, break-up fees and the
closing date and closing conditions, and authorized Chase Securities, AIP
management and counsel to continue negotiations with Lend Lease in accordance
with the committee's conclusions. The committee also reviewed and discussed the
response of DDR to the definitive term sheet submitted by AIP. DDR had rejected
the term sheet for several reasons including transaction costs, working capital
of AIP at closing and other cost assumptions. The committee concluded that an
agreement needed to be reached with DDR regarding these issues in order to
arrive at an acceptable minimum net price per share to AIP shareholders upon
consummation of the merger. The committee directed Chase Securities to continue
to negotiate with DDR to resolve these issues.


     On May 30, 2000, the board of trust managers held a meeting during which
the trust managers directed management to proceed with the listing and sale of
Manhattan Towers.


     On June 12, 2000, the special committee met to discuss the latest drafts of
the term sheets with Lend Lease and DDR. Following a detailed discussion, the
committee unanimously concluded that the proposed term sheet with DDR should be
revised to provide that it be structured as a merger directly into DDR or a
subsidiary of DDR, that non-DDR shareholders receive a net price of at least
$13.50 per share upon consummation of the transaction, that DDR agree not to
reduce the value attributable to the DDR portfolio based on further due
diligence and that DDR pay Lend Lease or reimburse AIP in the event that AIP is
required to pay a break-up fee or reimburse Lend Lease for out-of-pocket costs
due to DDR's actions or its failure to comply with the proposed term sheet or
other agreements.


     On June 13, 2000, the board of trust managers met and the special committee
reported that the transactions as currently proposed were unacceptable and that,
if the transactions were to proceed, DDR would have to commit to the items
discussed in the committee's June 12, 2000 meeting.

     On June 19, 2000, the special committee met to consider final drafts of the
term sheets with Lend Lease and DDR. The committee reviewed a proposed letter
agreement by which DDR agreed to the

                                       32
   39


merger consideration of not less than $13.50 per share and the other transaction
terms outlined by the special committee at its June 12 meeting, including the
extension of the termination date of the DDR share purchase commitment to AIP.
The committee also reviewed the exclusive negotiation agreement and term sheet
with Lend Lease, including the cost reimbursement obligation of AIP under
certain circumstances, the amount of loan assumption fees to be absorbed by Lend
Lease and the break-up fees payable by AIP in certain events. After discussion,
the special committee unanimously approved the proposed term sheets and related
documents with Lend Lease and DDR and concluded that the committee was prepared
to submit its recommendation to the AIP board that AIP enter into the
documentation and proceed to further negotiate the Lend Lease and DDR proposals.



     On June 22, 2000, the board of trust managers convened a special meeting.
Counsel for the special committee outlined the terms of the agreement reached on
June 19, 2000 between DDR and the special committee, including the minimum net
price per share of $13.50. Counsel for the special committee, management of AIP
and AIP legal counsel then discussed the status of the term sheet with Lend
Lease providing for the purchase of approximately $288.7 million of assets from
AIP. The chairman of the special committee stated that the recommendation of the
special committee to the board was to approve the execution of the DDR and Lend
Lease term sheets and related documents and proceed with the negotiation of the
definitive terms, provisions and conditions of the proposed transactions and the
definitive agreements. A general discussion on these proposed transactions
ensued. After discussion, the non-DDR trust managers unanimously authorized the
execution of the DDR and Lend Lease term sheets.



     Shortly after the June 22 board meeting, the term sheets and related
documents were executed and delivered by the parties. During the ensuing weeks,
counsel for the parties and their respective representatives and Chase
Securities prepared and negotiated the definitive documents for the proposed
sale to Lend Lease and the merger with DDR.



     On July 19, 2000 and July 24, 2000 the special committee met. At the first
meeting, the chairman raised concern about the valuation of the proposed Lend
Lease transaction. The chairman expressed his desire to reassess the
transactions in order to ensure that shareholder value would be maximized in the
event the pending transactions with Lend Lease and DDR were consummated. The
chairman explained that recent developments in the real estate market and the
anticipated price to be realized by AIP upon the proposed sale of Manhattan
Towers had caused him to reconsider the value of the properties to be sold to
Lend Lease. At the second meeting, the chairman again raised his concerns about
the valuation for the proposed transaction with Lend Lease. The special
committee reviewed Salomon Smith Barney's previous efforts on behalf of AIP to
solicit indications of interest from potential bidders. The committee was also
briefed on the risks and challenges of attempting to realize additional
incremental proceeds for the Lend Lease portfolio properties, including
execution risks, the necessity of maintaining the DDR bid proposal at its
current rate, the reimbursement of expenses to Lend Lease pursuant to the term
sheet and the risks associated with the likely type of purchaser for our
property type and related financing risks.



     On August 1, 2000, the special committee continued its discussions of the
$288.7 million purchase price to be paid by Lend Lease for certain of our
properties and reviewed strategic alternatives, including the implications of
pursuing the proposed transaction with DDR on a stand-alone basis.
Representatives of Chase Securities presented a strategic alternatives review
and summarized these strategic alternatives, the rationale for them, issues
presented in connection therewith and preliminary valuation considerations of
each of the following alternatives:



     - selling the Lend Lease portfolio and the Manhattan Towers property and
      merging the remaining company with DDR;



     - selling the Manhattan Towers property and continuing AIP as a going
      concern;



     - selling the Manhattan Towers property, liquidating the Lend Lease assets
      and merging the remaining company with DDR;



     - selling the Manhattan Towers property, selling assets to DDR and
      continuing the remaining company as a going concern; and

                                       33
   40


     - liquidating all of the AIP assets in a broadly marketed process.



While the special committee continued to evaluate the merger and the sale of
properties against the other alternatives throughout its deliberative process,
all alternatives to the transactions were ultimately rejected for various
reasons at the time the merger and sale of properties were approved. The
alternative of remaining independent was determined to be a less attractive
alternative to the merger and sale of properties because of the concern that the
lack of access to capital would cause AIP to stagnate and create downward
pressure on the market price of its common shares. Additionally, the committee
determined that the prospect of providing shareholders with a chance to sell
their shares in one transaction rather than trying to liquidate their positions
in the open market through a series of trades would help protect the value of
their investment. The alternatives of liquidating some or all of the AIP
properties over time were rejected because of the numerous risks associated with
trying to complete the transactions in a manner that would maximize value to
shareholders. These risks include difficulties in finding buyers for smaller
portfolios, the general lack of institutional buyer interest in AIP's property
type and the reduced likelihood of being able to recognize the same price for
the Lend Lease transaction properties on a property-by-property sale basis as
AIP will receive in the Lend Lease sale of properties.



     At the August 1, 2000 meeting, each member of the special committee stated
his views with respect to the proposed sale to Lend Lease and the DDR merger and
the chairman was requested to prepare a report of the special committee for
submission to the board of trust managers scheduled for the following day.
Messrs. Bricker and Giles each indicated they could not support the Lend Lease
transaction at the present pricing. Mr. Morris reiterated that the proposed sale
to Lend Lease and the DDR merger should be analyzed as a combined transaction
and on that basis he supported the transaction and felt that consummation of the
transaction was in the best interests of the AIP shareholders. The committee
chairman, Mr. Bricker, announced that he would report to the board of trust
managers that two members of the committee were concerned about the Lend Lease
pricing and that the committee intended to continue its deliberations before
making any decision with respect to a recommendation to the board.



     On August 2, 2000, the board of trust managers convened a regular quarterly
meeting. Mr. Bricker, the chairman of the special committee, indicated that he
could not support the Lend Lease transaction due to his unresolved concern over
the pricing of the proposed sale to Lend Lease. Mr. Giles, another member of the
special committee, indicated a similar concern with respect to then current
pricing and the timing of the Lend Lease transaction. Mr. Morris, the other
member of the special committee, indicated that he supported the Lend Lease and
DDR transactions at the revised pricing. After discussion, management was
authorized to extend the negotiation period under the exclusivity agreement with
Lend Lease to August 25, 2000 in order to determine if additional progress could
be obtained in negotiations with Lend Lease.


     On August 7, 2000, the special committee met to continue its discussion of
the portfolio valuation and the purchase price to be paid by Lend Lease for
specific properties of AIP. The committee unanimously concluded that a
recommendation should be made to AIP's board of trust managers that management
be instructed to enter into further negotiations with Lend Lease with a view to
increasing the price to be paid by Lend Lease for the properties to be acquired
pursuant to the Lend Lease proposal.

     On August 8, 2000, the board of trust managers met and Mr. Bricker reported
that the special committee had directed management to negotiate further with
Lend Lease on behalf of AIP.

     On August 9, 2000, the special committee met to review and discuss the
results of the negotiations between AIP management and representatives of Lend
Lease regarding the purchase price to be paid by Lend Lease for the Lend Lease
portfolio. Mr. Wolcott reported that Lend Lease had offered to increase its
purchase price by $3.5 million and agreed to certain modifications to the term
sheet for the proposed transaction as requested by the committee. At the
meeting, Mr. Bricker and Mr. Giles announced that neither of them intended to
vote for the proposed sale of assets to Lend Lease under the current terms. It
was unanimously determined that the special committee's current position be
conveyed to the board of trust managers at the meeting to be held following the
meeting of the special committee.

                                       34
   41


     On August 9, 2000, the trust managers met and Mr. Wolcott summarized the
results of negotiations with Lend Lease pursuant to the direction of the special
committee. Mr. Wolcott stated that he had conversations with representatives of
Lend Lease on August 8 and 9 and informed them that the special committee had
met and directed him to request an additional purchase price increase of Lend
Lease. Mr. Wolcott advised that the initial reaction of the Lend Lease
representatives was negative. Mr. Wolcott reported that, after several telephone
discussions, a representative of Lend Lease called and advised that Lend Lease
was willing to, among other things, increase its purchase price by $3.5 million
to $292.2 million. In consideration for this concession, Lend Lease proposed it
would receive an increased break-up fee of an additional $3.5 million if the
Lend Lease transaction did not occur and an extension of the exclusivity period
through August 18, 2000. Mr. Wolcott noted that the Lend Lease concession would
increase the minimum price per share upon consummation of the proposed
transactions to $13.67. Mr. Bricker then reported that the special committee had
met prior to this meeting and had considered this information. Mr. Bricker
stated that the informal recommendation of the special committee, with Mr.
Morris disagreeing, was to reject the Lend Lease transaction for the same
reasons previously discussed with the board. After further discussion of the
objections of the two special committee members as well as the terms of the Lend
Lease transaction, the board of trust managers agreed to extend the exclusivity
agreement with Lend Lease to August 25, 2000.



     On August 10, 2000, Mr. Giles resigned from the special committee for the
reasons that were outlined in his August 15, 2000 correspondence.



     On August 15, 2000, Mr. Giles notified counsel for the special committee
that he opposed the transactions because he believed the pricing was too low
based on Chase Securities' preliminary range of values for AIP's properties. Mr.
Giles also stated that he believed the timing of the transactions was poor, that
real estate was in a down market, that we should wait to sell until the market
improved, and the transactions would result in inadequate consideration to
shareholders.


     On August 15, 2000, Mr. Bricker notified the board that he opposed the
proposed transaction with Lend Lease. He stated that his opposition resulted
from several factors, including the fact that the Lend Lease purchase price was
at the low end of the valuation range prepared by Chase Securities, that the
aggregate purchase price paid by AIP for these properties was roughly the same
as the proposed aggregate sale price to Lend Lease, that net operating income on
these properties had increased since their purchase by AIP and that the
capitalization rate proposed to be paid on these properties by Lend Lease was
too high.

     On August 16, 2000, our trust managers met and Mr. Wolcott informed the
board that both Mr. Bricker and Mr. Giles had distributed letters to each of the
trust managers setting forth their opposition to the proposed transactions. The
trust managers discussed in detail Mr. Giles' and Mr. Bricker's stated
positions.


     On August 25, 2000, our trust managers met and Mr. Morris led a discussion
regarding the status of the Lend Lease transaction and the proposed merger with
DDR. After discussion, the board agreed to extend the exclusivity agreement with
Lend Lease until September 15, 2000. Mr. Bricker informed the trust managers
that he opposed the extension of the Lend Lease exclusivity agreement and he was
resigning from the special committee due to his opposition to the extension and
the Lend Lease transaction. After discussion of the objections of Messrs.
Bricker and Giles, as well as the then current terms of the Lend Lease and DDR
proposals, our non-DDR trust managers determined that the special committee
should proceed with Mr. Morris as the sole member and continue its evaluation of
the acquisition proposals.



     Between August 28, 2000 and September 13, 2000, Mr. Morris, as the sole
remaining member of the special committee, met on several occasions with Chase
Securities and the special committee's legal advisors, our management and AIP
legal counsel to discuss the status of negotiations with DDR and Lend Lease.
During this period, Mr. Morris, the sole member of the special committee,
engaged in direct negotiations with representatives of both DDR and Lend Lease
regarding the financial terms of the transactions.

                                       35
   42


     On August 29, 2000, Messrs. Schoff, Morris, Duncan and Wolcott, at Mr.
Morris' request, met at DDR's offices in Beachwood, Ohio to discuss outstanding
merger agreement issues, including indemnification, schedule of tenant
improvements, commissions and allowance to DDR for unspent amounts, transaction
costs and insurance coverage. Mr. Wolstein participated in portions of the
meeting.



     On August 30, 2000, at the request of the special committee, Mr. Wolcott
and Mr. Duncan, along with AIP's and the special committee's legal advisors,
held a telephone meeting to negotiate open legal issues. The participants in
this meeting, which was called by Messrs. Wolcott and Duncan, addressed the
significant remaining legal issues including the scope of indemnity and DDR's
obligations with respect to post-closing claims.



     On September 11, 2000, October 11, 2000 and October 20, 2000, Mr. Morris
held telephonic meetings with Mr. Schoff of DDR to negotiate open business
issues relating to the merger. Each of these meetings was called by Mr. Morris
and was intended to resolve the remaining open issues so that a definitive
agreement could be entered into between AIP and DDR. Among the issues addressed
were indemnification obligations, the amount and nature of the transaction
expenses, timing of the transaction and the impact of future operations and
distributions to AIP's shareholders on the merger price.


     On September 13, 2000, the board of trust managers convened a special
meeting. Mr. Morris reported that some issues relating to the DDR and Lend Lease
transactions had been resolved but other issues were outstanding. After
discussion of these items, Mr. Morris stated that the special committee's
recommendation was to move forward with the negotiations based on progress made
to date. Based on this recommendation, the trust managers agreed that additional
negotiations should proceed and the trust managers authorized a two-week
extension of the Lend Lease exclusivity period.


     Between September 20, 2000 and October 20, 2000, Mr. Morris, as the sole
remaining member of the special committee, met on several occasions with Chase
Securities, the special committee's legal advisors, our management and AIP legal
counsel to discuss the status of negotiations with DDR and Lend Lease. Mr.
Morris also engaged in direct negotiations with DDR representatives during this
period in an effort to increase the net price per share payable to non-DDR
shareholders upon consummation of the proposed transactions. During this period,
DDR, AIP and Lend Lease discussed which of DDR or Lend Lease would acquire the
outlying parcels associated with the Summit Park and Cameron Creek properties.
It was ultimately decided that the two parcels would remain with AIP and not be
sold to Lend Lease.



     On October 26, 2000, the sole remaining member of the special committee met
with the special committee's legal advisors, AIP's legal advisors and Chase
Securities to consider the proposed transactions and to discuss the status of
the Lend Lease and DDR definitive agreements. He reported, among other things,
that the agreements relating to the DDR and Lend Lease transactions, which had
been prepared originally in July 2000, had been negotiated extensively from July
through October and that DDR had agreed to a minimum merger consideration to
non-DDR shareholders of $13.74 per share. Mr. Morris announced that the
committee had determined to recommend to the board of trust managers that the
board approve the proposed transactions with Lend Lease and DDR, subject to
receipt of a favorable opinion from Chase Securities that the consideration to
be received by AIP's shareholders was fair from a financial point of view.
Representatives of Chase Securities reviewed with Mr. Morris the process
undertaken in connection with the issuance of a fairness opinion and the bases
on which the conclusions to be reached in the opinion would be made. Counsel for
the special committee and counsel for AIP then reviewed the material terms of
the agreements, including the pricing provisions, the termination provisions,
and the other recent revisions to the DDR merger agreement. Mr. Morris was also
briefed on the status of the Lend Lease transaction.



     By written consent dated November 1, 2000, Mr. Morris, as the sole
remaining member of the special committee, approved in all respects and
recommended to the entire board of trust managers the proposed sale of
properties to Value Enhancement Fund, the Lend Lease designee, and the proposed
merger with an affiliate of DDR for the purchase price (being a minimum net
price of $13.74 per share) and on the terms, provisions and conditions set forth
in the Lend Lease property sale agreement and the DDR merger agreement,
respectively.

     On November 1, 2000, a meeting of our board of trust managers was convened
and the special committee, the trust managers not designated by DDR,
representatives of Chase Securities, the special committee's legal advisors and
AIP's legal advisors discussed the proposed transactions. A representative of
the special committee's legal advisors outlined the review of the proposed
transactions undertaken by the special committee, the negotiation process and
the material terms of the transactions, including the merger consideration of
$13.74 per share and the condition that transaction costs at closing not exceed
$13.738 million. A representative of Locke Liddell & Sapp reviewed the fiduciary
duties of the board under the circumstances. Chase Securities delivered its oral
opinion to the special committee and, at the direction of the special committee,
to the non-DDR trust managers, confirmed by delivery of its written opinion to
the special committee dated November 1, 2000, that the $13.74 cash per AIP
common share to be received by the non-DDR holders of AIP common shares in the
merger was fair from a financial point of view to such holders. Chase Securities
also reviewed the financial analysis it performed. After considering these
matters, the sole member of the special committee submitted his recommendation
that the board approve and declare advisable the property sale and the merger,
that the transactions be submitted to the shareholders and that AIP's
shareholders approve the transactions.



     The DDR designated trust managers then joined the meeting. The trust
managers then voted on the transactions, which were considered together. Messrs.
Duncan, Kelly, Morris, Kraska and Wolcott voted in favor of the proposal.
Messrs. Giles and Bricker voted against the proposal. Messrs. Adams, Gidel,
Schoff and Wolstein abstained from the vote because of the conflict of interest
between their duties as members of the AIP board of trust managers and their
interest in the transaction on behalf of DDR. Prior to the vote, Mr. Kraska
reminded the board that, as he had previously disclosed, the LaSalle entities
have an ownership interest in DDR on behalf of certain clients.



     The board next discussed the need for agreement between management and AIP
regarding the severance and other payments due to management upon the sale of
properties to Lend Lease and the closing of the merger with DDR. The board then
voted on the mutual releases and settlement agreements to be entered into with
management in connection with the transactions. The DDR designees, because of
their conflict of interest, and Messrs. Bricker and Wolcott abstained, Mr. Giles
voted against the agreements and Messrs. Duncan, Kelly, Morris and Kraska voted
in favor of the agreements. Finally, the board voted on a proposal to approve
revised fees that would be owed by AIP to its financial advisors in connection
with the transactions. Messrs. Giles and Bricker voted against the proposal and
the other nine trust managers voted in favor of the proposal.


     Subsequent to the board meeting, the mutual release and settlement
agreements, voting agreements, the property sale agreement and the merger
agreement were executed.

     On November 2, 2000, prior to commencement of trading on the New York Stock
Exchange, AIP and DDR issued a joint press release announcing the transactions.

     On November 9, 2000, we sold our Manhattan Towers property to a third party
for gross proceeds of approximately $55.4 million.

DDR'S PURPOSE AND REASONS FOR THE MERGER

     DDR believes that the merger transaction and its unilateral control of
AIP's assets following the merger will enable DDR's shareholders and analysts
following DDR to more clearly understand the financial impact to DDR of its
investment in the light industrial/office properties of AIP. Additionally, DDR
believes that although AIP's business is not directly complementary to that of
DDR and its subsidiaries, DDR can obtain operating benefits and cost savings by
integrating some of AIP's operations into DDR and its subsidiaries.

     At the present time, DDR's only cash return on its investment in AIP is the
distributions it receives on the AIP common shares it owns. However, if AIP were
wholly-owned by DDR, decisions could be made solely by DDR regarding AIP's
operations and the use of AIP's cash flow. DDR determined that it was an
appropriate time to make its acquisition offer to AIP based on its knowledge of
the real estate

                                       37
   44


industry, its assessment of the underlying value of AIP's assets and DDR's
desire to take advantage of the benefits described below under "-- Benefits of
the Merger to DDR."


BENEFITS OF THE MERGER TO DDR

     Following the merger, DDR will become the sole shareholder of AIP and,
therefore, will have unilateral control over the assets of AIP remaining after
the sale to Value Enhancement Fund and the closing of the merger. DDR believes
the value of AIP can be enhanced following the merger by the following:

     - AIP will become a private company as a result of the merger and will,
       therefore, have greater operating flexibility, allowing it to focus on
       enhancing value by emphasizing growth and the operating cash flow without
       the constraint of the public market's emphasis on quarterly earnings;

     - the elimination of the costs associated with being a public company
       should reduce the overall operational and administrative costs of AIP
       following the merger;

     - DDR will be able to manage directly the assets of AIP and thereby combine
       AIP's operations with its other activities to enable DDR to obtain
       certain operating efficiencies with respect to the remaining assets of
       AIP after the merger;

     - DDR will no longer have a contingent obligation to purchase additional
       shares from AIP;

     - DDR's sole control of the AIP assets will enable the public market to
       assess more clearly the value of the assets to DDR; and

     - DDR plans to make efforts to dispose of AIP's properties in an orderly
       manner over time, and, therefore, could realize a profit on the sale
       depending upon its ability to increase the value of the properties after
       the merger, and market conditions at the time of sale.

POSITION OF DDR REGARDING FAIRNESS OF THE MERGER

     DDR believes that the merger and the $     per share merger consideration
are fair, from a financial point of view, to the holders, other than DDR, of
AIP's common shares. The amount of the merger consideration was determined by
management of DDR after considering the factors set forth below and following
negotiations with the special committee of the AIP board of trust managers. The
factors considered by management of DDR included the following:

     - the historical and projected financial performance of AIP;


     - that the $     per share merger consideration (including the $1.27 per
       share special distribution on January 17, 2001), represents approximately
       a      % premium over the closing price for the AIP common shares on
       November 1, 2000, the last full trading day prior to announcement of the
       merger;


     - that the merger is not subject to DDR obtaining financing to consummate
       the merger;


     - that the merger provides the public shareholders who are considering
       selling their AIP common shares with the opportunity to exchange their
       shares for $     per share in cash without incurring the transaction
       costs typically associated with market sales;



     - that the closing market price of AIP after January 1, 2000 was below the
      per share merger consideration on each trading day, except for 10 days,
      and that for most of 2000, the market price was in the $10.00 to $13.00
      range;



     - that the going concern value of AIP, in DDR's view, was less than the per
      share merger consideration;



     - in DDR's view, AIP's future growth prospects as a going concern are not
      favorable in light of (1) the factors described in the second paragraph
      under the "Background of the Merger" section


                                       38
   45


      beginning on page 25, (2) AIP's relatively high overhead expenses, (3)
      AIP's relatively low property occupancy rates, (4) the fact that some of
      AIP's older properties require substantial maintenance, (5) the lack of
      equity research analyst coverage, (6) the relatively low trading volumes
      and the lack of liquidity in AIP stock, and (7) the current market
      environment of rising interest rates and cap rates for property sales;



     - that under the terms of the merger agreement, if AIP sells all or
      substantially all of its properties within six months after the merger is
      consummated and the net aggregate sale price exceeds the aggregate
      agreed-upon property value, the non-DDR shareholders will share in the
      benefit by receiving a pro rata share of the excess;



     - that the liquidation value per share of AIP would be less than the merger
      consideration because, among other things, AIP is not required to pay in
      the merger the substantial closing costs that would be applicable to a
      sale of its properties (including loan assumption fees or loan prepayment
      costs). Further, in DDR's view, any liquidation of AIP would have involved
      a lengthy and uncertain process before the AIP shareholders would have
      received any consideration for their shares; and



     - the ability of shareholders who object to the merger to obtain "fair
      value" for their shares if they exercise and perfect their dissenters'
      rights under the Texas REIT Act;



     DDR did not find it practicable to, and therefore did not, quantify or
otherwise assign relative weights to the individual factors it considered in
reaching its conclusion as to fairness. DDR did not consider the net book value
of AIP in its determination of fairness relating to the non-DDR shareholders,
nor did DDR consider the purchase prices paid by DDR for AIP shares in the last
two years under the 1998 agreement with AIP which is described on page 39. Those
purchase prices were established by a negotiated contract entered into in June
1998 and were not relevant to whether the merger consideration is fair to
non-DDR shareholders under the economic and market conditions existing in
November 2000. Other than as described in "Background of the Merger" on pages
25-37, DDR is not aware of any firm offer made to AIP by any unaffiliated
persons during the last two years. The "Background of the Merger" section
describes the extensive attempts by AIP from early 1999 to maximize the value of
AIP to its shareholders through, among other things, the sale of AIP. No person
or entity has agreed to a price higher than the merger consideration.



FINANCIAL PROJECTIONS



  DDR's Use of Projections



     In connection with DDR's review of AIP and in the course of its
negotiations with AIP, AIP did not provide projections to DDR. DDR's
representatives on AIP's board of trust managers received information for each
of the quarterly board meetings that contained AIP management's one-year
projections. DDR did not develop long-term financial projections for AIP.

  Special Committee's Use of Projections



     Our management and Chase Securities presented the special committee with
financial projections for AIP and its subsidiaries based on our management's
internal projections that had been furnished to Chase Securities. The
projections furnished to the special committee are summarized in the following
table.



                             SUMMARY OF PROJECTIONS

     These projections are included in this proxy statement only because this
information was furnished to and considered by the special committee in
connection with their consideration of the transactions. The projections were
not prepared with a view to public disclosure or compliance with the published
guidelines or policies of the SEC or the guidelines established by the American
Institute of Certified Public Accountants. The projections are not presented in
accordance with the U.S. GAAP and our independent auditors have not examined or
compiled the projections and accordingly assume no responsibility for them.
Financial projections are, in general, subjective in many respects and thus
susceptible to interpretations and periodic revision based on actual experience
and business developments. These projections also reflect numerous assumptions
with respect to industry performance, general business, economic, market and
financial conditions and other matters, all of which are difficult to predict,
and many of which are beyond our control. Accordingly, the assumptions may not
prove accurate. It is expected that there will be differences between actual and
projected results, and actual results may be materially better or worse than
those contained in the projections. The inclusion of projections in this proxy
statement should not be relied upon as a prediction of future events. Neither
AIP nor any of its affiliates or representatives has made or makes any
representation to any person regarding the ultimate performance of AIP, its
subsidiaries or its property portfolio compared to the information contained in
the projections, and none of them intends to update or otherwise revise the
projections to reflect circumstances existing after the date when made or to
reflect the occurrence of future events even in the event that any or all of the
assumptions underlying the projections are shown to be in error.



     In view of the wide variety of factors considered by the special committee,
including, without limitation, those factors described above, the special
committee did not find it practicable to, and did not, quantify or otherwise
attempt to assign relative weights to the specific factors considered. The
special committee viewed its positions and recommendations as being based on the
totality of the information presented to, and considered by, it. After taking
into consideration all the factors set forth below, the special committee
determined that the potential benefits of the transactions outweighed the
potential detriments associated with the transactions.



RECOMMENDATION OF THE SPECIAL COMMITTEE AND THE BOARD OF TRUST MANAGERS; REASONS
FOR THE TRANSACTIONS



     In its deliberations with respect to the proposed transactions, the entire
special committee and the board consulted with our management and our financial
and legal advisors, and it was the committee's objective to maximize shareholder
value. With limited access to equity or debt capital to expand AIP, the entire
special committee recommended the pursuit of strategic alternatives. The entire
special committee directed its advisors to evaluate the proposals for the entire
company and pursue various strategies to maximize shareholder value. It was the
view of the sole remaining member of the committee that the perception in the
marketplace for the prospects of AIP's assets would begin to diminish as the
economy began to slow, which would negatively impact access to capital, future
growth prospects and shareholder value, thus reducing financial returns to
shareholders. In addition, because AIP's asset class does not


                                       40
   47


generate significant interest for institutional investors, any rebound in the
REIT market would likely have less of a positive impact on AIP than on REITs in
other sectors.



     After considerable review, in the business judgment of the sole remaining
member of the special committee, the best alternative to maximize shareholder
value and financial returns to shareholders was to sell AIP. Importantly, the
sole member of the special committee wanted to ensure that if a buyer emerged
for a large portion of the company, that another buyer or merger candidate for
the remainder of the company (including the assumption of all liabilities and
contingent liabilities) be identified, thus maximizing shareholder value and
financial returns to shareholders.



     THE BOARD OF TRUST MANAGERS, ACTING ON THE RECOMMENDATION OF THE SOLE
REMAINING MEMBER OF THE SPECIAL COMMITTEE, HAS BY A MAJORITY VOTE OF THE TRUST
MANAGERS NOT DESIGNATED BY DDR, APPROVED THE MERGER AGREEMENT AND THE SALE
AGREEMENT AND RECOMMENDED THAT HOLDERS OF OUR COMMON SHARES VOTE FOR THE
PROPOSED TRANSACTIONS. FOR THE REASONS DESCRIBED UNDER "FAIRNESS OF THE MERGER;
OPINION OF FINANCIAL ADVISOR," THE MAJORITY OF OUR TRUST MANAGERS NOT DESIGNATED
BY DDR AND THE SOLE REMAINING MEMBER OF THE SPECIAL COMMITTEE BELIEVE THAT THE
PROPOSED TRANSACTIONS ARE FAIR TO, AND IN THE BEST INTERESTS OF, OUR
SHAREHOLDERS. OF OUR 11 TRUST MANAGERS, FIVE MEMBERS VOTED FOR, TWO VOTED
AGAINST, AND THE FOUR DDR DESIGNEES ABSTAINED ON, THE PROPOSAL TO APPROVE THE
MERGER AGREEMENT AND THE SALE AGREEMENT. OUR TWO TRUST MANAGERS WHO RESIGNED
FROM THE SPECIAL COMMITTEE VOTED AGAINST THE PROPOSED TRANSACTIONS. THE REASONS
THEY VOTED AGAINST THE TRANSACTIONS ARE DESCRIBED IN "-- BACKGROUND OF THE
MERGER" ON PAGE 25.



     In consideration of the recommendation of the special committee and board
with respect to the proposed transactions, you should be aware that some of our
trust managers and management of AIP have interests in the merger that may
conflict with the interests of our shareholders generally. The board and special
committee were aware of these interests and considered them, among other
matters, in approving the merger agreement and the sale agreement. See "Benefits
to Insiders" on page 51.



     The factors considered by the special committee and the board in
determining whether to approve the merger and the sale of properties include
those enumerated below. While all of these factors were considered by the
special committee and the board, neither the special committee nor the board
made determinations with respect to each of these factors separately. Rather,
the special committee and the board each made its respective judgment with
respect to the merger agreement and the sale agreement based on the total mix of
information available to it, and the judgments of individual trust managers may
have been influenced to a greater or lesser degree by their individual views
with respect to different factors. Both the special committee and the board
considered the proposed transactions with DDR and Value Enhancement Fund as one
transaction and voted on them as one transaction. The closing of the merger is
contingent upon the closing of the sale of properties and the sale of the
properties is contingent upon the approval of the merger by our shareholders. As
our special committee rejected the alternative of a partial sale of assets
followed by either remaining independent or pursuing a liquidation of the
remaining assets, neither the special committee nor the board would approve the
closing of one transaction unless the other transaction was likewise closing.



     In making its decision to approve the merger agreement and the sale
agreement, each of the special committee and the board considered the following
supporting factors, which were all of the material factors considered by the
special committee and the board:


     - The board and the special committee believed that they had thoroughly
       explored other alternatives to maximize shareholder value, including
       remaining independent or engaging in a transaction with a third party.


     - The board and the special committee believed, based on discussions with
       third parties and active negotiations with DDR, that the merger
       consideration was the best price that could be obtained by AIP in light
       of the available alternatives.



     - The special committee received, and the board relied upon, the opinion of
       Chase Securities as to the fairness from a financial point of view to the
       public shareholders of the merger consideration and the analysis
       presented to the special committee by Chase Securities.

                                       41
   48

     - If DDR causes AIP to sell all or substantially all of its properties
       remaining after the sale to Value Enhancement Fund during the six months
       following the effective date of the merger for more than the agreed upon
       values of the properties, our shareholders will receive their pro rata
       part of the sales proceeds based upon AIP share ownership prior to the
       merger.


     - The board and the special committee believed that the other terms of the
       merger agreement and the sale agreement were fair to AIP and its
       shareholders. Specifically, the board and the special committee
       considered:


          - the representations and warranties made by each party;

          - the covenants of the parties and the effect of those provisions on
            our operations prior to the merger;


          - the provisions that permit the special committee and the board to
            withdraw or modify their respective recommendations regarding the
            merger and the sale of properties;


          - the provisions that allow the board to accept a superior proposal;
            and


          - the limited number of conditions to the obligations of DDR, DDR Sub
            and Value Enhancement Fund, which should increase the likelihood of
            a timely consummation of the sale of properties and the merger.



       These provisions made the board believe that the transactions had a high
       probability of closing, and gave the board the flexibility to terminate
       the proposed transactions and pursue the superior transactions if any
       were presented.


     - The alternative courses of action available to AIP given

        - the limited possibilities for AIP to expand through acquisitions given
          AIP's limited access to capital;

        - the fact that few parties expressed an interest in acquiring AIP
          despite an exhaustive search on behalf of AIP by AIP's financial
          advisor for an acquiror; and

        - the fact that there could be no assurance that if AIP did not move
          forward immediately with Value Enhancement Fund and DDR, either or
          both of them would not terminate their offers.


     - The right of shareholders who do not vote in favor of the merger to
       exercise dissenters' rights. If you do not believe you will receive fair
       value for your shares, you may ask the court to determine the fair value
       of your shares.


     - The historical and projected financial performance of AIP.


     - The merger consideration represents an approximate 9.9% premium over the
       closing price for the common shares on November 1, 2000, the last full
       trading day prior to announcement of the merger.



     The special committee and the board also considered the negative factors
discussed below in their deliberations concerning the sale of properties and the
merger:



     - that two of the three members of the special committee resigned because
      of concerns over the price to be paid by Value Enhancement Fund for the
      properties and the timing of the transactions;



     - that, following the merger, shareholders will cease to participate in our
       future earnings or growth, if any, and to benefit from increases, if any,
       in our value;


     - the potential or actual conflicts of interest of our officers and trust
       managers in connection with the merger; and


     - that the merger will be a taxable transaction to our shareholders.


                                       42
   49


     The sole member of the special committee believes the sale of properties
and the merger is procedurally fair because:



     - although the special committee initially consisted of three non-employee
       trust managers, the sole remaining committee member was not our employee,
       and therefore had no expectation to derive any personal financial benefit
       from the merger different from that of any other shareholder and thus
       could, without question of self-dealing, negotiate on an arm's-length
       basis with representatives of DDR and Lend Lease on your behalf;



     - the special committee and the board had each considered DDR's and Lend
       Lease's proposals on numerous occasions, thereby maintaining continuously
       sufficient information to reach an informed business decision on each of
       DDR's and Lend Lease's proposals;


     - the special committee was advised by independent outside legal counsel
       and an independent financial advisor, which helped to ensure that the
       special committee understood its responsibility to recommend only a
       transaction that was in your best interests, and that the special
       committee pursued that goal independently, in good faith and diligently;
       and


     - we had thoroughly explored the other alternatives prior to entering into
       agreements with each of Lend Lease and DDR, which provided a basis for a
       determination of our value as a going concern and to consider the
       adequacy of the consideration offered by DDR.


BENEFITS AND DETRIMENTS TO NON-DDR SHAREHOLDERS


     AIP and DDR believe the merger and the sale of properties is fair, from a
financial point of view, to the non-DDR shareholders and will result in the
following benefits to AIP's public shareholders: (1) the non-DDR shareholders
will realize the value of their investment in AIP in cash at a total price
(including the amount of the special distribution) which represents a 9.9%
premium to the market price for the common shares prior to the announcement of
the transactions and (2) the transactions eliminate the risk of a decline in the
value of their investment in AIP. The principal detriment to the non-DDR
shareholders of the completion of the sale of properties and the merger is that
they will cease to have any ownership interest in AIP and, therefore, will cease
to participate in future earnings or growth, if any, of AIP and to benefit from
increases, if any, in the value of AIP. In addition, the non-DDR shareholders
may recognize a taxable gain upon completion of the merger.


SOURCE AND AMOUNT OF FUNDS; FINANCING FOR THE MERGER


     We estimate that the total amount of funds required to purchase all of our
outstanding shares, other than the excluded shares, under the merger agreement
and to pay related fees will be approximately $     million. A portion of these
funds has been obtained through the sale of our Manhattan Towers property, which
generated net proceeds to us of approximately $34.2 million. We will obtain net
proceeds of approximately $     from the sale of our portfolio of 31 properties
to Value Enhancement Fund, and approximately $     from operations. Any
remaining amount necessary to close the merger will be borrowed under our
existing line of credit with Bank One Texas, N.A. As of February   , 2001,
$     principal amount was outstanding under the Bank One line of credit.


     We expect the amount outstanding under this line of credit prior to the
merger, assuming retirement of the Prudential Securities Credit Corporation
acquisition line described below, will be approximately $28.0 million. The Bank
One line was initiated on January 28, 1999 and, assuming adequate collateral
availability, has a maximum borrowing amount of $50 million. The line matures on
January 28, 2001. We are currently in negotiations with Bank One to extend this
line for an additional year. The Bank One line is a secured line and we
currently have 18 properties pledged as collateral for this line. Six of those
properties will be sold to Value Enhancement Fund. We currently intend to retire
our acquisition line with Prudential Securities Credit with proceeds of
borrowing under the Bank One line and to transfer the four properties
collateralizing the Prudential Securities Credit line to the Bank One line.
Assuming completion of this transaction in the merger, 16 properties would serve
as collateral for the Bank One line. The Bank

                                       43
   50


One line provides for a variable rate of interest based upon our debt ratio in
effect from time to time. The line of credit currently bears interest at 1.75%
over the 30 day LIBOR rate, or 7.46%. The Bank One line contains typical
borrowing covenants and restrictions. We are currently in compliance with all of
these restrictions. The consent of Bank One will be required to close the
merger. We have reached tentative agreement with Bank One to extend the maturity
of this line to January 28, 2002. We are currently documenting this agreement
and expect to execute the extension prior to maturity of the line of credit.


FAIRNESS OF THE MERGER; OPINION OF FINANCIAL ADVISOR


  General



     The board and special committee of AIP believe that the merger and the sale
of properties are fair, from a financial point of view, to the AIP shareholders,
other than DDR. The reasons for this belief include the factors supporting the
transactions analyzed by the AIP board and special committee described above as
well as the following factors relating to the valuation of the transactions.
None of these factors was given paramount importance in the decision making
process.



     - The per share consideration (including the $1.27 per share special
      distribution) being received in the merger represents an approximate 9.9%
      premium over the closing price of the AIP common shares on November 1,
      2000, the last trading day before the announcement of the merger.



     - As described above under the caption "-- Background of the Merger," the
      board and the special committee evaluated the alternatives of AIP
      remaining independent or liquidating its assets. In each case, the special
      committee determined that the value to be received by the shareholders in
      the merger will be greater than that which could be realized from
      continuing as a going concern or liquidating.



     - The fact that the market price of the AIP common shares had deteriorated
      over the past 18 months and the prospect that sustained market prices
      above the merger consideration were not likely in the foreseeable future.



     - The consideration proposed by the few other entities who had expressed an
      interest in acquiring all or substantially all of the assets of AIP was
      inferior to that being offered by DDR and Value Enhancement and none of
      those other proposals resulted in a firm offer.



     - The fairness opinion provided by Chase Securities, as more fully
      described below.



In making the determination as to the fairness of the merger and the sale of
properties, neither the special committee nor the board of AIP evaluated the net
book value of AIP's assets or the purchase price in previous sales of its common
shares to DDR. Since the AIP common shares are trading at a discount to its net
book value per share, the special committee did not believe that analyzing the
net book value would be helpful in determining the fairness of the merger
consideration. The special committee did not believe that the sales to DDR were
indicative of either the current or future market value of the AIP common shares
because those sales were made in accordance with contractually specified sale
prices.



  Fairness Opinion of Chase Securities


     At meetings of the special committee and, at the direction of the special
committee, the board of trust managers on November 1, 2000, Chase Securities
gave its oral opinion, confirmed in writing, addressed to the special committee
and to be relied upon by the board of trust managers, that, as of November 1,
2000, the date of the opinion, and based upon the assumptions made, matters
considered and limits of review set forth in the opinion, the cash consideration
to be paid to the holders of common shares in the proposed merger is fair from a
financial point of view to the common shareholders. Based on the terms of the
merger agreement on that date, the per share cash consideration to be received
by the holders of common shares was $13.74 per share. DDR, DDR Sub and their
respective direct and indirect subsidiaries will not receive any of the merger
consideration. The amount of the merger consideration was determined through
negotiation between the special committee, with the assistance of Chase
Securities,

                                       44
   51


and DDR. Chase Securities is under no obligation to update its fairness opinion
and Chase Securities will not be asked to update the fairness opinion unless
there is a material change in the terms of the merger, such as a decrease in the
amount of merger consideration to be received by the shareholders other than
because of dividends or distributions being paid to shareholders.


     Chase Securities was retained to act as financial advisor to the special
committee of the board of trust managers and to render an opinion to the special
committee as to the fairness, from a financial point of view, of the per share
cash consideration to be received by the holders of common shares of AIP (other
than DDR and any of its affiliated entities).

     Chase Securities rendered its opinion to the special committee on November
1, 2000, to the effect that, as of that date, and based upon the assumptions
made, matters considered, and limits of review set forth in its opinion, the per
share cash consideration to be received by the holders of common shares of AIP
(other than DDR and any of its affiliated entities) pursuant to the merger
agreement, subject to adjustment, was fair from a financial point of view, to
the holders of common shares (other than DDR and any of its affiliated
entities). In rendering its opinion, Chase Securities was informed by AIP that
the consummation of the merger is contingent upon the consummation of the sale
of a portfolio of 31 properties to Value Enhancement Fund for not less than
$135.4 million cash consideration, net of related closing costs, repayment of
indebtedness for money borrowed secured by the Lend Lease portfolio and related
prepayment penalties and fees, and the consummation of the sale of Manhattan
Towers for not less than $34.2 million cash consideration, net of related
closing costs, repayment of indebtedness for money borrowed secured by the
Manhattan Towers and related prepayment penalties and fees.

     In rendering its opinion, Chase Securities assumed that AIP and certain
wholly-owned subsidiaries, as applicable, will receive no less than $135.4
million cash consideration for the sale of the 31 property portfolio, net of
related closing costs, repayment of indebtedness for money borrowed secured by
the portfolio and related prepayment penalties and fees, and AIP will receive no
less than $34.2 million cash consideration for the sale of Manhattan Towers, net
of related closing costs, repayment of indebtedness for money borrowed secured
by Manhattan Towers and related prepayment penalties and fees.

COMMON SHARES SHOULD VOTE, OR AGREE TO VOTE, WITH RESPECT TO THE MERGER. THE
SUMMARY OF CHASE SECURITIES' OPINION SET FORTH BELOW IS QUALIFIED IN ITS
ENTIRETY BY REFERENCE TO THE FULL TEXT OF THE WRITTEN OPINION ATTACHED HERETO AS
APPENDIX A. THE HOLDERS OF COMMON SHARES ARE URGED TO READ THE ENTIRE OPINION
CAREFULLY. CHASE SECURITIES HAS CONSENTED TO THE INCLUSION OF ITS OPINION, DATED
NOVEMBER 1, 2000, AND THE REFERENCES TO ITS OPINION IN THIS PROXY STATEMENT.


     In arriving at its opinion, Chase Securities, among other things:

     - reviewed drafts of the merger agreement, the purchase and sale agreement
       and the Manhattan Towers purchase and sale agreement in the forms
       provided to them, including the most recent drafts dated October 31, 2000
       and has assumed that the final forms of such agreements, as applicable,
       will not vary in any regard that is material to its analysis;

     - reviewed certain publicly available business and financial information it
       deemed relevant relating to AIP and the industries in which AIP operates;

     - reviewed certain internal non-public financial and operating data
       provided to it by the management of AIP relating to AIP's business,
       including certain forecast and projection information as to future
       financial results of such business;
                                       45
   52

     - discussed with members of the senior management of AIP, AIP's operations,
       historical financial statements and future prospects, before and after
       giving effect to the merger and the sale of the portfolio to Value
       Enhancement Fund and the sale of Manhattan Towers, as well as such other
       matters as it deemed necessary or appropriate;

     - compared the financial and operating performance of AIP with publicly
       available information concerning certain other companies and businesses
       it deemed reasonably comparable and reviewed the relevant stock market
       information for such other companies;

     - reviewed the financial terms of certain recent business combinations and
       acquisition transactions it deemed reasonably comparable to the merger
       and the sale of the 31 property portfolio and the sale of Manhattan
       Towers and otherwise relevant to its inquiry; and


     - made such other analyses and examinations as it deemed necessary or
       appropriate, including those described below under the headings "-- Chase
       Securities Liquidation Analysis" on page 50, "-- Dividend Discount
       Analysis" on page 50, and "Free Cash Flow Analysis" on page 50.


     Chase Securities assumed and relied upon, without assuming any
responsibility for verification, the accuracy and completeness of all of the
financial and other information provided to, discussed with, or reviewed by or
for Chase Securities, or publicly available, for purposes of the opinion and
further relied upon the assurances of management of AIP that it was not aware of
any facts that would make that information inaccurate or misleading. Chase
Securities neither made nor obtained any independent evaluations or appraisals
of the assets or liabilities of AIP nor did Chase Securities conduct a physical
inspection of the properties and facilities of AIP. Chase Securities assumed
that the financial forecast and projection information provided to or discussed
with it by or on behalf of AIP were reasonably determined on bases reflecting
the best currently available estimates and judgments of the management of AIP as
to the future financial performance of AIP. We refer you to the information
under the heading "Financial Projections" below. Chase Securities expressed no
view as to such forecast or projection information, or the assumptions upon
which it was based.

     In connection with the preparation of its opinion, Chase Securities was not
authorized by AIP or the special committee to solicit, nor did Chase Securities
solicit, offers from third parties for the acquisition of all or any part of the
equity or assets of AIP.

     Chase Securities' opinion was necessarily based on market, economic and
other conditions as they existed and could be evaluated on the date of its
opinion. The opinion was limited to the fairness, from a financial point of
view, to the holders of the trust common shares of AIP (other than DDR, DDR Sub
and their respective direct and indirect subsidiaries) of the per share cash
consideration to be received in the merger and Chase Securities expressed no
opinion as to the underlying decision by AIP to engage in the merger, the sale
of the portfolio to Value Enhancement Fund or the sale of Manhattan Towers.
Chase Securities also expressed no opinion on matters of a tax, accounting or
legal nature related to the merger, the sale of the portfolio or the sale of
Manhattan Towers. Chase Securities' opinion does not constitute a recommendation
to any holder of equity interests in AIP as to how such holder should vote, or
agree to vote, with respect to the merger.


     The following is a summary of the material financial analyses performed by
Chase Securities and reviewed with the special committee in connection with
Chase Securities' presentation on November 1, 2000 and its opinion to the
special committee. Chase Securities has presented some of the summaries in
tabular format. In order to understand the financial analysis more fully, you
should read the tables together with the text of each summary. The summary set
forth below does not purport to be a complete description of the analyses
performed by Chase Securities in arriving at its opinion. Arriving at a fairness
opinion is a complex process not necessarily susceptible to partial analysis or
summary description. Chase Securities believes that its analyses must be
considered as a whole and that selecting portions of analyses and of the factors
considered by it, without considering all these factors and analyses, could
create a misleading view of the processes underlying its opinion. No company or
transaction used in the analyses set forth below as a comparison is directly
comparable to AIP or the proposed merger. Chase Securities

                                       46
   53

did not assign relative weights to any of its analyses in preparing its opinion.
The matters considered by Chase Securities in its analyses were based on
numerous macroeconomic, operating and financial assumptions with respect to
industry performance, general business and economic conditions and other
matters, many of which are beyond AIP's control and involve the application of
complex methodologies and educated judgment. Any estimates incorporated in the
analyses performed by Chase Securities are not necessarily indicative of actual
past or future results or values, which may be significantly more or less
favorable than these estimates. Estimated values do not purport to be appraisals
and do not necessarily reflect the prices at which businesses or companies may
be sold in the future, and these estimates are inherently subject to
uncertainty. Such analyses were prepared solely as part of Chase Securities'
analysis of the fairness, from a financial point of view to the holders of
common shares (other than DDR, DDR Sub and their respective direct and indirect
subsidiaries) of the per share consideration to be received by such holders in
the merger.


     Transaction Consideration.  For purposes of its analysis, Chase Securities
assumed the following:



     - the sale of properties to Value Enhancement Fund, the sale of the
      Manhattan Towers property and the merger with DDR would all occur as a
      single transaction;



     - AIP's net debt at January 31, 2001 would be $314.0 million; and



     - the total transaction value was $602.4 million.



The assumed transaction value was calculated by multiplying the per share
consideration of $13.74 multiplied by the number of shares outstanding (20.992
million), which equals an approximate total equity value of $288.4 million. The
total equity value of $288.4 million plus net debt of $314.0 million projected
for the consummation of the merger on January 31, 2001, including transaction
expenses and contingency reserves, equals a total transaction value of $602.4
million.



     Comparable Company Analysis.  Chase Securities reviewed and compared the
operating performance and financial condition of five selected publicly traded
REITs, which are referred to collectively as the "comparable companies," using
publicly available information, with that of the operating performance and
financial condition of AIP. The comparable companies were selected based on
market capitalization, property type and asset quality. Such comparable
companies consisted of the following:


     - Bedford Property Investors;

     - Brandywine Realty Trust;

     - EastGroup Properties Inc.;

     - Keystone Properties Trust; and

     - PS Business Parks.

     Chase Securities' analysis included, among other things, a review of:

     - total market capitalization, calculated by adding equity market value and
       total debt, preferred units and preferred stock;

     - ratios of price per share to funds from operations, "FFO," per share;

     - ratios of price per share to adjusted funds from operations, "AFFO," per
       share; and

     - ratios of total market capitalization to earnings before interest
       expense, taxes, depreciation and amortization, "EBITDA."

     Chase Securities calculated the ratio of price per share as of October 27,
2000 to FFO per share using projected 2000 and 2001 FFO per share, as provided
by Realty Stock Review, a national data service that monitors and publishes
compilations of earnings estimates by selected research analysts regarding
companies of interest to institutional investors, the ratio of price per share
as of October 27, 2000 to

                                       47
   54

AFFO per share using projected 2000 and 2001 AFFO per share based on equity
analyst research reports and total market capitalization to EBITDA using
projected 2000 and 2001 EBITDA based on equity analyst research reports.

     These analyses showed the following:



                                                                SUGGESTED
                                                                MULTIPLE

                                                               COMPARABLE     MULTIPLES FOR
                                                                COMPANIES      TRANSACTION

Total Market Capitalization to estimated next year EBITDA...    9.0x-10.5x         9.7x


     The implied multiples for the transaction were calculated using the $13.74
per share consideration that would be distributed to holders of common shares
(other than DDR, DDR Sub and their respective direct and indirect subsidiaries)
and the $602.4 million transaction value of the merger. Based on these analyses
and AIP's estimated current year FFO, estimated next year FFO, estimated current
year AFFO, estimated next year AFFO, estimated current year EBITDA, and
estimated next year EBITDA, Chase calculated that the per share value implied by
the transaction based on the multiples of the comparable companies was $8.40,
using the estimated current year AFFO to $16.06, using the estimated current
year EBITDA.

     None of the comparable companies were identical to AIP and, accordingly, an
analysis of the foregoing necessarily involved complex considerations and
judgements concerning the differences in financial and operational
characteristics of the companies involved and other factors that could affect
the companies compared to AIP.

     Precedent Transaction Analysis.  Based upon publicly available information,
Chase analyzed the purchase price and transaction value multiples of
transactions for five selected corporate transactions involving the sale or
merger of the entire target company, which are referred to collectively as the
"precedent transactions." The precedent transactions were chosen based on a
review of target companies that had general business, operating and financial
characteristics representative of companies in the industry in which AIP
operates. The precedent transactions reviewed were:



ANNOUNCEMENT DATE                                 ACQUIRORS                       TARGETS
- -----------------                                 ---------                       -------
                                                                   
6/16/99..............................  Starwood Financial Trust          Trinet Corporate Realty

7/09/98..............................  Reckson Associates/Metropolitan   Tower Realty
12/23/97.............................  Highwoods Properties              J.C. Nichols Company


     In connection with its analysis, Chase Securities calculated for each of
the precedent transactions:

     - the purchase price,

     - total transaction value calculated by adding purchase price, total debt,
       preferred units and preferred stock;

     - ratios of offer price per share to FFO per share;

     - ratios of offer price per share to AFFO per share; and

     - ratios of total transaction value to EBITDA.

                                       48
   55

     Chase Securities calculated the ratio of offer price per share to FFO per
share and AFFO per share using projected FFO and AFFO for the year in which the
transaction was announced and the year following the announcement of the
transaction and total transaction value to EBITDA using projected EBITDA for the
year in which the transaction was announced and the year following the
announcement of the transaction.

     The results of this comparison were as follows:



                                                                SUGGESTED

Total Market Capitalization to estimated next year EBITDA...    10.5x-12.0x         9.7x


     The implied multiples for the transaction were calculated using the $13.74
per share consideration that would be paid to holders of common shares (other
than DDR, DDR Sub and their respective direct and indirect subsidiaries) and the
$602.4 million transaction value for the merger. Based on these analyses and
AIP's estimated current year FFO, estimated next year FFO, estimated current
year AFFO, estimated next year AFFO, estimated current year EBITDA and estimated
next year EBITDA, the per share value implied by the suggested multiple range
for precedent transactions was $9.45, using the estimated current year AFFO to
$20.50, using the estimated next year EBITDA.

     None of the selected precedent transactions reviewed were identical to the
merger and, accordingly, an analysis of the foregoing necessarily involved
complex considerations and judgments concerning differences in financial and
operational characteristics of the companies involved and other factors,
including the general market conditions prevailing in the equity capital markets
at the time of the transaction, that could affect the precedent transactions
compared to the transactions.

     Chase Securities Estimated Adjusted Net Asset Value.  Chase Securities
performed a net asset value calculation that was preceded by due diligence which
included:

     - a discussion with AIP management concerning the leasing and cap rate
       environment for each of its markets;

     - a review of AIP's historical and current year budgets;

     - a review of AIP prepared ARGUS cash flow projections;

     - a review of AIP prepared rent rolls;

     - a review of AIP's capital expenditure budget and year to date repair
       reports;

     - the completion of precedent property sales analysis for each of AIP's
       markets; and


     - site visits to selected properties which included property tours and
       discussions with on-site management and third party brokers, but did not
       include physical inspections of such properties.



     Following this diligence, Chase Securities applied cap rates to AIP's 2000
budgeted net operating income (adjusted for a 3.0% property management fee and
$0.10 psf capital expenditure reserve) that took into consideration
market-by-market supply and demand fundamentals, market specific leasing
conditions, tenant quality, and building age from which gross real estate asset
value was calculated. Properties with occupancy rates in excess of 90% were
considered stabilized, properties with occupancy rates less than 90% were
assumed to have been leased up to 94% and properties with 100% occupancy were
assumed to


                                       49
   56


have a 97% occupancy rate. Chase Securities then applied a 5% premium and 5%
discount to this value that resulted in a gross real estate asset value range of
$593.4 million to $650.2 million. In calculating estimated net asset value,
Chase Securities subtracted net debt of $314.0 million from the gross real
estate asset value range that resulted in an estimated net asset value range of
$279.4 million to $336.2 million. Chase Securities then divided the net asset
value range by 20.992 million common shares outstanding to calculate a net asset
value range of $13.31 to $16.01 per share. Finally, Chase Securities adjusted
its estimated net asset value range for transaction expenses of $13.7 million
that resulted in an estimated adjusted net asset value range of $12.66 to 15.36
per share.


     Chase Securities Liquidation Analysis.  Chase Securities performed a
liquidation analysis for AIP based upon projections and assumptions provided by
AIP's management of projected net operating income and the projected debt
balance for the year ended December 31, 2000. Under the liquidating analysis,
AIP was liquidated over a 24-month period. Under the liquidation analysis, net
operating income growth was approximately 3.0% per annum after the first two
quarters until the end of the 24-month period. Additionally, Chase Securities
assumed that Manhattan Towers was sold for net proceeds of $34.4 million. AIP's
general and administrative expenses were assumed to be $1.146 million in the
first two quarters and to decline by 10% in the next two quarters and decline by
50% thereafter. Capital expenditures, tenant improvements and leasing costs are
assumed to be 15% of the net operating income. Chase Securities sold a
percentage of assets per quarter at various cap rates, ranging from
10.25%-11.00% in the conservative scenario and 9.75% to 10.50% in the aggressive
scenario, and correspondingly reduced the amount of debt and interest expense
for each quarter's disposition. Chase Securities applied this methodology
throughout the eight quarters to arrive at the total amount of proceeds from
asset sales. Finally, Chase Securities took this amount and reduced it by the
total amount of debt associated with the sales, along with various costs
associated with the liquidation process, to arrive at the total liquidation
proceeds. Chase Securities calculated the net present value of the total
liquidation proceeds using 15%, 17.5% and 20.0% discount rates and then divided
by the total shares outstanding (20.992 million) to arrive at a per share
liquidation value. The Chase Securities liquidation analysis resulted in values
ranging from $12.08 to $13.78 per share.

     Dividend Discount Analysis.  Chase Securities performed a dividend discount
analysis for AIP based upon projections and assumptions provided by AIP's
management of projected FFO per common share and projected annual dividend
payouts per common share for the years ending December 31, 2001 to December 31,
2006. Under the dividend discount model methodology, implied equity values are
estimated by discounting dividends per share for the years 2001 through 2005
using discount rates reflecting an expected equity total return and calculating
a terminal value by applying exit multiples on projected 2006 FFO for AIP. Chase
Securities used discount rates ranging from 15.0% to 18.0% and terminal
multiples of 7.0x to 9.0x. The present value of the dividends and the terminal
value were added together to determine a range of equity values for AIP which
ranged from $236.7 million to $316.6 million. On a per share basis, assuming
20.992 million common shares outstanding, this equated to $11.27, using a
terminal multiple of 7.0x and a discount rate of 18.0% to $15.08, using a
terminal multiple of 9.0x and a discount rate of 15.0%.


     Free Cash Flow Analysis.  Chase Securities performed a discounted free cash
flow analysis for AIP based upon projections and assumptions provided by AIP's
management of projected net operating income and projected free cash flow for
the years ending December 31, 2001 to December 31, 2006. Under the discounted
free cash flow model methodology, implied equity values are estimated by
discounting free cash flow for the years 2001 through 2005 using discount rates
reflecting an expected equity total return and calculating a terminal value by
applying exit cap rates to projected 2006 net operating income for AIP. Chase
Securities used terminal cap rates of 10.0% to 12.0% and discount rates ranging
from 15.0% to 18.0%. Chase Securities selected these ranges of discount rates
and terminal value cap rates based on a review of the comparable companies
listed under the caption "-- Comparable Company Analysis" above. The present
value of free cash flow and the terminal value were added together to determine
a range of equity for AIP which ranged from $242.4 million to $327.0 million. On
a per share basis, assuming 20.992 million common shares outstanding, this
equated to $11.55, using a terminal cap rate of 12.0% and a discount rate of
18.0% to $15.58, using a terminal cap rate of 10.0% and a discount rate of
15.0%.

     AIP retained Chase Securities to act as exclusive financial advisor to the
special committee based upon its experience and expertise. Chase Securities, as
part of its financial advisory business, is continually engaged in the valuation
of businesses and their securities in connection with mergers and acquisitions
and valuations for estate, corporate and other purposes. The Chase Manhattan
Corporation and its affiliates, including Chase Securities, in the ordinary
course of business, may have from time to time, provided, and in the future may
continue to provide, for customary compensation, commercial and investment
banking services to AIP, DDR, Lend Lease and their respective affiliates,
including serving as agent bank for the Lend Lease credit facility, serving as
agent bank for the Lend Lease Global Properties, SICAF, credit facility and
serving as agent bank for the Lend Lease (U.S.) Finance, Inc., credit facility.
In the ordinary course of business, Chase Securities or its affiliates may trade
in the debt and equity securities of AIP and DDR and their respective
affiliates, for their own accounts and for the accounts of their customers and,
accordingly, may at any time hold a long or short position in such securities.

     AIP entered into a letter agreement with Chase Securities, dated May 5,
2000 which sets forth the terms of Chase Securities' engagement, as financial
advisor to the special committee. Pursuant to the terms of the letter agreement,
AIP has paid and agreed to pay Chase Securities the following fees for its
services rendered in connection with the merger:

     - a retainer fee of fee of $500,000, $100,000 of which was paid upon the
       execution of the letter agreement and the remaining $400,000 of which was
       paid in four equal monthly installments of $100,000 per month for the
       four months immediately following the month in which the letter agreement
       was executed; and


     - a transaction fee of $2,000,000, payable upon the consummation of the
       merger, subject to adjustment upward based upon the final consideration
       received by holders of common shares (other than DDR, DDR Sub and their
       respective direct and indirect subsidiaries), in an amount equal to 5% of
       the consideration received by shareholders in excess of $14.50 per common
       share, without deducting transaction expenses.


AIP has also agreed to reimburse Chase Securities for its legal expenses
incurred in connection with its preparation and delivery of its opinion, and for
its other reasonable expenses incurred in connection with its engagement, and to
indemnify Chase against certain liabilities incurred in connection with its
engagement, including liabilities under the federal securities laws.


BENEFITS TO INSIDERS



     In considering the recommendations of the board of trust managers and the
sole member of the special committee, you should be aware that some of our
members of management and trust managers have interests in the merger that are
different from, or in addition to, your interest as a shareholder generally.
These conflicts of interests are further described below and under the caption
"Proposal Number One: The Merger; Special Factors -- Background of the Merger"
beginning on page 25.


                                       51

     AIP Shares.  Our common shares held individually by our officers and trust
managers will be converted into the right to receive the same merger
consideration as shares held by other shareholders. The total amounts that our
trust managers and executive officers will receive for their shares are listed
in the table above.

     Shares Options and DERs.  The terms of our options provide that all
outstanding options will automatically accelerate on a change in control. We
have taken the necessary actions to provide for the cancellation at the time the
merger becomes effective of all outstanding options to acquire common shares in
exchange for a per option cash payment equal to the cash merger consideration of
$     , less the then current exercise price of the option immediately before
the effective time. At the effective time, our trust managers and executive
officers will receive the cash payments listed in the table above for DERs and
options that they hold based on an average price of $2.909 per DER and the
excess of $     over the then current exercise price per share of the options.
The payment for termination of the DERs was negotiated by the sole member of the
special committee and management and approved by our board.

     Officers' and Trust Managers' Indemnification and Insurance.  The merger
agreement provides that we will indemnify our and our subsidiaries' present and
former officers, employees, trust managers and directors from liabilities
arising out of actions or omissions in these capacities prior to the time the
merger becomes effective, to the same extent as provided in our organizational
documents or any written indemnification agreements or under any of our benefit
plans. In addition, we will maintain directors' and officers' insurance coverage
for six years after the effective time of the merger on terms no less favorable
to these indemnified parties than existing insurance coverage. DDR has
guaranteed the performance of these AIP obligations.

     The LaSalle Entities.  The LaSalle entities, on behalf of their clients,
own beneficially or have voting control of 7.6% of DDR's outstanding common
stock.

TRANSACTIONS AND RELATIONSHIPS BETWEEN AIP AND DDR

     Under the share purchase agreement dated as of July 30, 1998, between AIP
and DDR, as amended, DDR purchased 2,207,624 common shares of AIP for
$14,711,778 in cash and the transfer of five properties from DDR to AIP. In
November 1998, in a subsequent closing under the purchase agreement, AIP issued
2,815,192 common shares to DDR in exchange for the cancellation of $43,635,476
in aggregate principal amount of outstanding debt owed to DDR by AIP. This
transaction included undeveloped land purchased by AIP from DDR in the amount of
$2.3 million plus interest, which land was then contributed by AIP to a joint
venture with a third party.

     From November 20, 1998 through November 20, 2000, AIP had the option under
the share purchase agreement to sell to DDR additional common and/or preferred
shares for an aggregate purchase price that did not exceed in the aggregate
$200,000,000. Any common shares sold to DDR would be at a price of $15.50 per
share. If DDR became the owner of 49.9% of our outstanding shares, we could sell
only preferred shares to DDR, at a price of $14.00 per share. These per share
prices were subject to downward adjustment if the closing price for AIP common
shares for the 10 days preceding the date we exercised our option was below
$12.12 per share. After DDR had funded $100 million of this additional
commitment, we could require DDR to purchase an additional $100 million in AIP
common shares or preferred shares, depending on whether DDR owned 49.9% of all
outstanding common shares, only so long as:

     - the trading price of DDR common stock was above $18.00; and

     - DDR's aggregate investment in AIP did not exceed 10% of DDR's market
       capitalization.

     The proceeds of any share sale to DDR were to be used solely for the
purpose of funding property acquisitions approved by a majority of the members
of the board of trust managers that were not affiliates of the seller of the
property or of the assignor that assigned its right to acquire the property to
AIP. This additional purchase option could only be exercised by action of a
majority of our trust managers, excluding the trust managers designated by DDR.
In December 1998, pursuant to this additional purchase option, AIP issued an
aggregate of 868,386 of its common shares to DDR in exchange for $13,459,993 to
fund property acquisitions by AIP in accordance with the terms of the purchase
agreement. All common shares issued by AIP under the purchase agreement prior to
January 15, 1999 were sold to DDR at a price of $15.50 per common share. In
January 1999, AIP issued 3,410,615 common shares to DDR in exchange for
$48,800,000 to fund certain property acquisitions by AIP in accordance with the
terms of the purchase agreement and the cancellation of $3,000,000 in aggregate
principal amount of outstanding debt owed to DDR by AIP. Of those shares,
1,543,005 common shares were issued at a price of $15.50 per common share and
1,867,610 common shares were issued at a price of $14.93 per common share. In
August 1999, AIP issued 354,839 common shares to DDR in exchange for $5,500,000
to fund certain property acquisitions by AIP in accordance with the terms of the
purchase agreement. AIP issued these shares at a price of $15.50 per common
share. At November 1, 2000, the date the merger agreement was signed, $166.6
million remained outstanding under our additional purchase option. If the merger
does not close by May 31, 2001 because of a breach of the merger agreement by
DDR or DDR Sub, we will regain our

                                       53
   60

right to cause DDR to purchase up to $166.6 million of preferred shares or
additional common shares from AIP. AIP's right would be extended for a period of
time from its original termination date of November 20, 2000 by the number of
days between June 19, 2000 and the later of (1) the date on which the breach
occurs or (2) the first date on which a trust manager not designated by DDR
becomes aware of the breach.

     Effective October 8, 1998, AIP acquired from DDR an 88.5% limited
partnership interest in DDR/ Tech 29 Limited Partnership, a limited partnership
whose assets consist of two light industrial properties and one office property
totaling 290,991 sq. ft., located in Silver Springs, Maryland. In consideration
for the property and for accrued interest on other borrowings, AIP issued
approximately $16.1 million in common shares to DDR. The shares issued were
valued at $15.50 per share.


     During 1998, AIP on occasion entered into unsecured borrowings with DDR.
These borrowings had a fixed rate of interest of 10.25%, provided for quarterly
payments of interest and were due 30 days after demand. The highest amount
outstanding under such borrowings from DDR during 1998 was $23.51 million. The
total amount of interest on such borrowings during 1998 was $661,000 and the
balance outstanding at December 31, 1998 was $14.058 million.


     In December 1999, AIP repaid in full the borrowings from DDR made in 1998
to finance acquisitions. AIP also paid interest of $111,000 to DDR at the time
of that repayment.


     AIP paid DDR approximately $19,000, $17,000 and $28,000 in management fees
for the years ended December 31, 1998, 1999 and 2000, respectively, for
services, including, but not limited to, construction, tenant finish, leasing
and management services.


CHANGE IN CONTROL PAYMENTS

     In December 1998, when DDR had purchased in excess of 33% of our
outstanding shares, we made change in control payments under the bonus and
severance agreements to our executive officers, and the options, restricted
shares and DERs held by them vested as follows:



                                                                              RESTRICTED

SHARE PURCHASES

     None of AIP, its trust managers or executive officers, DDR Sub or DDR and
its affiliates has engaged in any transaction with respect to AIP common shares
within 60 days prior to the date of this proxy statement.

     The following table sets forth purchases of AIP common shares by AIP during
1998, including, by quarter, the number of shares purchased and the high, low

Merger -- Transactions and Relationships between AIP and DDR."

MATERIAL FEDERAL INCOME TAX CONSEQUENCES

     The following is a summary of the material federal income tax consequences
of the merger to holders of our common shares. This summary does not address all
aspects of federal income taxation that may be relevant to our common
shareholders in light of their particular circumstances or to common
shareholders subject to special treatment under the federal income tax laws.
These shareholders may include financial institutions, tax-exempt organizations,
insurance companies, dealers in securities or currencies, shareholders holding
shares as part of a conversion transaction, as part of a hedge or hedging
transaction, or as a position in a straddle for tax purposes, or shareholders
who acquired our shares in connection with the exercise or other satisfaction of
compensatory options. In addition, the summary below does not consider the
effect of any foreign, state, local or other tax laws that may be applicable to
the merger. The discussion assumes that common shareholders hold their common
shares as capital assets and not as inventory or as property held primarily for
sale to customers in the ordinary course of a trade or business. This summary is
based upon the provisions of the Internal Revenue Code of 1986, treasury
regulations, Internal Revenue Service rulings and judicial decisions, all in
effect as of the date hereof and all of which are subject to change by
subsequent legislative, judicial or administrative action. Some of these changes
may possibly be retroactive. This summary is for general informational purposes
only and is not tax advice.

     Dividends.  Distributions paid on our common shares, other than the merger
consideration, generally will constitute dividends for U.S. federal income tax
purposes and will be taken into account as ordinary income to the extent paid
from our current or accumulated earnings and profits, as determined under U.S.
federal income tax principles, and then will constitute a return of capital that
is applied against a shareholder's basis in the shares to the extent these
distributions exceed those earnings and profits. Distributions in excess of our
current or accumulated earnings and profits and a shareholder's basis in the
shares will be treated as a gain from the sale or exchange of the shares. As
long as AIP qualifies as a REIT, corporate shareholders will not be eligible for
the dividends received deduction as to such amounts.

     Holders of Shares.  In general, upon receipt of the merger consideration, a
holder of our common shares will be treated as if their common shares had been
redeemed. Such redemption of common shares will be a taxable transaction. The
U.S. federal income tax consequences of the redemption to a shareholder will
depend on whether, based on such shareholder's particular circumstances, such
shareholder qualifies for capital gain or loss treatment under section 302 of
the Internal Revenue Code. If a shareholder does not qualify for capital gain or
loss treatment, the redemption will be taxable to the shareholder as a dividend.

     If the shareholder will not actually or constructively own shares of any
class of stock of AIP or DDR immediately after the redemption, such shareholder
will qualify for capital gain or loss treatment under section 302 of the
Internal Revenue Code. In such case, the shareholder will recognize capital gain
or loss equal to the difference between the amount of cash received in the
redemption and its adjusted tax basis in the redeemed shares. Such gain or loss
will be long-term capital gain or loss if the shareholder held such shares for
more than one year at the time of the redemption.

     If a shareholder actually or constructively owns shares of any class of
stock of AIP or DDR immediately after the redemption of AIP's common shares, the
shareholder should consult its tax advisor regarding the U.S. federal income tax
consequences of the redemption in its particular situation, including the
possibility that the receipt of any proceeds in the redemption will be treated
as a dividend taxable as ordinary income.

     Foreign Shareholders.  In the case of any foreign shareholder, for United
States federal income tax purposes, i.e. a non-resident alien individual, a
foreign corporation, or a foreign estate or trust, except as set forth in the
next paragraph, we will withhold 30% of the merger consideration payable to the
foreign shareholder in order to satisfy certain withholding requirements in
connection with the receipt of fixed or determinable annual or periodical gains,
profits, and income, unless the foreign shareholder proves in a
                                       55
   62

manner satisfactory to us that either (a) the redemption of its common shares
pursuant to the merger will qualify as a sale or exchange with respect to such
foreign shareholder under Section 302 of the Internal Revenue Code, rather than
as a dividend for federal income tax purposes, in which case no withholding will
be required, except as otherwise provided herein, (b) the foreign shareholder is
eligible for a reduced tax treaty rate with respect to dividend income, in which
case we will withhold at the reduced treaty rate, or (c) no withholding is
otherwise required. Foreign shareholders are urged to consult their own tax
advisers regarding the application to them of these withholding rules and other
tax consequences of the merger to them.


     Under the Foreign Investment in Real Property Tax Act of 1980, a common
shareholder that is a foreign shareholder will generally not be subject to U.S.
federal income or withholding tax on the gain recognized on the disposition of
our common shares pursuant to the merger if (a) we are a "domestically
controlled REIT" within the meaning of the Internal Revenue Code; or (b) our
common shares are regularly traded on an established securities market within
the meaning of the Internal Revenue Code and the shareholder does not own,
actually or constructively under attribution rules provided in the Internal
Revenue Code, in excess of 5% of the fair market value of all of our common
shares outstanding at any time during the shorter of the five-year period
preceding the merger or the shareholder's holding period. We believe that we are
a "domestically controlled REIT." We also believe that our common shares are
regularly traded on an established securities market within the meaning of the
Internal Revenue Code. We will endeavor to determine whether our common shares
continue to be regularly traded on an established securities market prior to the
merger and whether we are a "domestically controlled REIT" as of the effective
time of the merger. A foreign shareholder of our common shares who does not meet
either of the above exceptions will be subject to (a) United States federal
income tax at regular graduated rates on any gain recognized on the disposition
of its shares in the merger; and (b) withholding in respect of this tax at a
rate of 10% of the amount realized by the foreign shareholder in the merger.
Foreign shareholders are urged to consult their tax advisors concerning the
potential applicability of these exceptions and the consequences of a sale or
other disposition of the common shares held by foreign shareholders in advance
of the merger.


     Certification of Non-Foreign States.  In order to avoid withholding under
the Foreign Investment in Real Property Tax Act of 1980, a shareholder of our
common shares who is not a foreign shareholder must certify under penalties of
perjury as to its non-foreign status by completing the certification form that
will be included with the letter of transmittal in connection with the merger.

     Backup Withholding.  The exchange of common shares in the merger will be
reported to the Internal Revenue Service. Backup withholding at a rate of 31%
will apply to the merger proceeds unless the exchanging shareholder furnishes a
taxpayer identification number in the manner prescribed by applicable Treasury
regulations, certifies that the number is correct, certifies as to no loss of
exemption from backup withholding and meets other conditions. Backup withholding
does not apply to foreign shareholders, corporations and other exempt
non-foreign shareholders. A foreign shareholder will be exempt from backup
withholding if the applicable certification requirements are satisfied. The
payment or distribution of merger proceeds to or through the United States
office of a broker is subject to information reporting and backup withholding
unless an exemption from information reporting and backup withholding is
established. Any amounts withheld under the backup withholding rules described
above will be allowed as a refund or a credit against United States federal
income tax liability of the shareholder if the required information is furnished
to the Internal Revenue Service on a timely basis.

     DUE TO THE INDIVIDUAL NATURE OF TAX CONSEQUENCES, YOU ARE URGED TO CONSULT
YOUR TAX ADVISORS AS TO THE SPECIFIC TAX CONSEQUENCES TO YOU OF THE MERGER,
INCLUDING THE EFFECTS OF APPLICABLE STATE, LOCAL OR OTHER TAX LAWS.

PLANS FOR AIP AFTER THE MERGER


     If DDR completes the merger, it intends to maintain AIP as a private REIT
which will operate AIP's remaining properties and implement an orderly
disposition plan. In connection with that plan, DDR will attempt to achieve an
acceptable price for each of the AIP properties. Any disposition of properties
will be supervised by DDR's commercial real estate professionals. The
disposition plan may involve individual assets, a select group of properties, or
the sale of the entire portfolio. In order to achieve an acceptable return in
connection with the sale of the properties, some of the properties may require
that capital expenditures be made in order to upgrade the condition of the
properties or may require that they be more fully leased. At this time, DDR does
not have any agreement and has not entered into any letter of intent to sell any
of the AIP properties. DDR will take certain steps after the approval of the
merger to (1) retain AIP's status as a REIT (although private), and (2) prevent
AIP from becoming a qualified REIT subsidiary of DDR. In addition, there are no
current plans or proposals which relate to or would result in:


     - an extraordinary corporate transaction, such as a merger, reorganization
       or liquidation involving AIP;

     - a sale or transfer of a material amount of AIP's assets; or

     - any other material change in AIP's corporate structure or business.

     DDR's management has begun and intends to continue a study of AIP and its
assets, corporate structure, capitalization, operations, properties, policies,
management and personnel to determine what changes will be desirable following
completion of the merger in order to organize and integrate AIP's activities
with those of DDR and its other subsidiaries.

CONDUCT OF THE BUSINESS OF AIP IF THE MERGER IS NOT COMPLETED

     If the merger is not completed, AIP's board of trust managers expects that
AIP's current management will continue to operate AIP's business substantially
as currently operated. AIP anticipates that DDR would continue to be a
substantial shareholder and have the right to nominate four of the 11 members of
the board of trust managers. AIP's board is not currently considering any other
alternative to the merger.


     If the merger does not close by May 31, 2001 because of a breach of the
merger agreement by DDR or DDR Sub, we will retain our right to cause DDR to
purchase up to $166.6 million of preferred shares or additional common shares
from AIP. The purchase price for the shares would be based upon AIP's trading
price. AIP's right would be extended for a period of time from its original
termination date of November 20, 2000 by the number of days between June 19,
2000 and the later of (1) the date on which the breach occurs or (2) the first
date on which a trust manager not designated by DDR becomes aware of the breach.
If AIP had this right, the board would consider whether the sale of shares would
be in the best interests of shareholders. If so, and if there were appropriate
property acquisitions to be funded in connection therewith, it would require
that DDR purchase shares from AIP.


ANTICIPATED ACCOUNTING TREATMENT OF THE MERGER

     The merger is expected to be accounted for using the purchase method of
accounting in accordance with GAAP.

REGULATORY APPROVALS RELATING TO THE MERGER

     No party is required to make filings with or obtain approvals from
regulatory authorities in connection with the merger, other than the filing of
articles of merger with Dallas County and the Secretary of State of the State of
Texas.

PROVISION FOR NON-DDR SHAREHOLDERS

     Neither DDR nor AIP has made any provision to grant non-DDR shareholders
access to the files of AIP or DDR or to obtain counsel or appraisal services at
their expense.

LITIGATION RELATING TO THE MERGER


     On November 3, 2000, a purported shareholder class action and derivative
action lawsuit was filed in Dallas County Court at Law No. 1. On November 21,
2000, two additional purported shareholder class action and derivative action
lawsuits were filed in the 68th and 134th Judicial District Courts in Dallas
County, Texas. Each lawsuit was filed by a shareholder of AIP seeking, among
other things, to enjoin the consummation of the merger. DDR and our trust
managers have been named as defendants in the lawsuits. AIP has been named as a
nominal defendant in the County Court at Law No. 1 lawsuit and as a defendant in
the latter two lawsuits.



     Each of the three actions is similar. The complaints allege that the
defendants have breached fiduciary duties, abused their control of AIP, and
committed waste by agreeing to the terms of the announced merger and that the
defendants will be unjustly enriched in connection with the proposed merger.
Each plaintiff has also sued for unspecified damages, punitive damages and
attorneys' fees. The defendants deny the plaintiffs' allegations of wrongdoing
and intend to vigorously defend themselves.


                              THE MERGER AGREEMENT

     The following describes the material terms of the merger agreement. The
full text of the merger agreement is attached to this proxy statement as
Appendix B and is incorporated in this proxy statement by reference. We
encourage you to carefully read the entire merger agreement.

GENERAL

     The merger agreement provides that upon the terms and subject to the
conditions of the merger agreement, DDR Sub will be merged with and into us and
that, following the merger, the separate existence of DDR Sub will cease and we
will continue as the surviving entity. When the merger occurs:

     - each outstanding share of common stock of DDR Sub will be converted into
       a common share of AIP;

     - each outstanding AIP common share held by non-DDR shareholders will be
       converted into the right to receive $       in cash, without interest and
       any additional consideration that may be payable to current shareholders
       upon the sale of AIP's remaining properties as described on page   ; and

     - common shares and share options held by DDR, DDR Sub or their affiliates
       (other than individuals) will be canceled in the merger.

     The amount of merger consideration may be reduced if dividends are paid to
maintain REIT status or to avoid REIT taxable income for federal income tax
purposes.

EFFECTIVE TIME OF THE MERGER

     The merger agreement provides that if all the conditions to the merger
agreement are satisfied or waived prior to the special meeting, the closing of
the merger will take place as soon as practicable following the special meeting.
Promptly after the closing, we and DDR Sub will file the necessary documents
with public officials to complete the merger. We expect that, if all conditions
to the merger have been satisfied or waived, the merger will occur within three
business days after the special meeting.

CONSEQUENCES OF THE MERGER

     Pursuant to the merger agreement, following approval and adoption of the
merger and subject to the fulfillment or waiver of the conditions to closing,
DDR Sub will be merged with and into AIP and AIP will continue as the surviving
entity in the merger. As a result of the merger, each common share of AIP issued
and outstanding immediately prior to the completion of the merger, other than
the excluded shares described below, will be automatically converted into the
right to receive cash as described above. The AIP common shares that will not be
converted into the merger consideration are:

     - shares held in AIP's treasury, which will be canceled without any payment
       thereon;

     - shares held by DDR, DDR Sub and their direct or indirect subsidiaries,
       which will be canceled without any payment thereon; and

     - shares held by shareholders who have perfected their dissenters' rights,
       which will be subject to appraisal in accordance with Texas law.

     At the completion of the merger, all AIP common shares, other than the
shares for which dissenters' rights were perfected, will no longer be
outstanding and will be canceled and retired and will cease to exist, and each
certificate formerly representing those shares will thereafter represent only
the right to receive the merger consideration. Also, on completion of the
merger, each share of DDR Sub common stock will be canceled and automatically
converted into the right to receive one AIP common share. Therefore, following
the merger, the non-DDR shareholders will cease to participate in future
earnings or growth, if any, of AIP or benefit from any increases, if any, in the
value of AIP and they will no longer bear the risk of any decrease in value of
AIP. Distributions by AIP after completion of the merger will be paid to DDR as
the sole shareholder of AIP and not to the non-DDR shareholders. The rate of
distributions after the completion of the merger may be greater than the rate of
dividends currently paid by AIP.

     The AIP common shares are currently registered under the Securities
Exchange Act of 1934. Following the merger, the common shares will become
eligible for termination of that registration and AIP's registration under the
Securities Exchange Act will be terminated. Additionally, the AIP common shares
will be delisted from the New York Stock Exchange. AIP's obligations to file
reports with the SEC will also be terminated. In addition, AIP will be relieved
of its obligation to comply with the other requirements of the Securities
Exchange Act, including the proxy rules, the short-swing trading profits
provisions and, with respect to future transactions involving AIP, the "going
private" provisions of Rule 13e-3 under the Securities Exchange Act.
Accordingly, less information will be required to be made publicly available
than is currently the case. DDR, however, will continue to be a publicly traded
and reporting company.

EMPLOYEE SHARE PLAN

     At the effective time, each option to purchase our common shares, other
than those held by DDR, will be converted into the right to receive an amount in
cash equal to the difference between the cash merger consideration and the then
current exercise price of the option. Also at the effective time, each DER will
be converted into the right to receive the negotiated average price of $2.909
per DER.

SURRENDER AND EXCHANGE OF SHARE CERTIFICATES; PAYMENT FOR SHARES


     Promptly after the time the merger becomes effective, AIP will deposit with
BankBoston, N.A., the exchange agent, an amount of cash equal to the aggregate
amount of cash merger consideration to be paid to holders of our common shares
immediately before the merger became effective and the amount of the final
dividend, if any. A final dividend will be paid from operating revenue generated
after the anticipated closing date, but only if the closing is delayed more than
three days beyond that date. Any final dividend paid because of a delay in
closing will not reduce the amount of merger consideration paid to shareholders.
The exchange agent will then send to persons who held our common shares
immediately before the merger


                                       59
   66

became effective a letter of transmittal containing instructions for use in
effecting the exchange of their AIP share certificates for the merger
consideration payable to them. If you held our common shares immediately before
the effective time of the merger, upon surrender to the exchange agent of an
outstanding certificate or certificates which represented our shares and
acceptance of such certificate by the exchange agent, the exchange agent will
deliver to you the merger consideration owed to you pursuant to the merger
agreement. No interest will be paid or accrue on any cash payable to you.

     Any portion of the merger consideration payable which remains undistributed
for two years after the effective time will be delivered to AIP. If, at that
time, you have not previously exchanged your certificates, you may thereafter
only look to AIP, and then only as a general creditor, for payment of the merger
consideration owed to you.

     If you do not have your share certificate, you may make an affidavit of
that fact. In addition, we may require that you post a bond in a reasonable
amount determined by us with respect to the missing share certificate. Upon
receipt of the affidavit and any required bond, the exchange agent will issue
the merger consideration payable to you.

TRANSFER OF SHARES

     At and after the effective time, our transfer agent will not record on the
share transfer books transfers of any of our common shares that were outstanding
immediately prior to the effective time of the merger.

OFFICERS, TRUST MANAGERS AND GOVERNING DOCUMENTS

     From and after the effective time of the merger, Messrs. Wolstein, Gidel,
Adams and Schoff will remain as trust managers of AIP. Our other trust managers
and our officers will resign on or prior to the effective time. Our declaration
of trust and bylaws in effect immediately prior to the effective time will
continue to be our governing documents after the merger, each until later
amended.

     - their capital structure;

     - litigation matters and compliance with law; and

CONDUCT OF BUSINESS PRIOR TO THE MERGER

     We have agreed, prior to the time the merger occurs, to operate our and our
subsidiaries' businesses in the ordinary course in substantially the same manner
as previously conducted and to use all commercially reasonable effects to
preserve intact our business organization, and retain the services of our
current officers and key employees.

     In addition, the merger agreement places specific restrictions on our
ability and the ability of our subsidiaries to:

     - except as described below, authorize, declare or pay any dividends on or
       make other distributions in respect of any of our common shares;

     - make or rescind any material express or deemed tax election;

     - materially change our methods, principles or practices of accounting
       except as required by the SEC, GAAP or applicable law;

     - acquire or enter into any option or contract to acquire additional real
       property;

     - incur additional indebtedness except for working capital under our
       revolving lines of credit;

                                       61
   68

     - encumber assets;

     - commence construction of, or enter into agreements to develop or
       construct, other real estate projects;

     - amend our organizational documents;

     - change our capital structure;

     - issue securities or change the terms of any outstanding securities;

     - sell, dispose of or agree to sell or dispose of any of our properties;

     - make loans, advances, capital contributions or investments in any entity
       other than our subsidiaries;

     - commit to purchase real estate in excess of $500,000 individually and
       $1,000,000 in the aggregate;

     - guarantee indebtedness;

     - enter into any related party transactions;

     - increase compensation or enter into employment or other agreements;

     - adopt any new employee benefit plan;

     - change the ownership of our subsidiaries; or

     - agree, commit or arrange to take any action listed above.


Under the merger agreement, we are permitted to pay a dividend, but only in the
minimum amount necessary to avoid jeopardizing our status as a REIT under the
Internal Revenue Code and having positive REIT taxable income for federal income
tax purposes. Any dividends paid for these purposes will reduce the amount of
the merger consideration. On January 17, 2001, in order to avoid having REIT
taxable income for 2000, we made a special distribution to shareholders of
record on December 29, 2000, of $1.27 per share. Accordingly, in accordance with
the merger agreement, the merger consideration was reduced by $1.27 per share.
We may also pay a dividend from operating revenues if the closing occurs after
          , 2001. A dividend paid for that purpose would not reduce the amount
of the merger consideration.


ACCESS TO INFORMATION

     We have agreed to allow DDR and DDR Sub, their officers, employees,
accountants, counsel, financial advisors and other representatives, upon
reasonable advance notice, reasonable access during normal business hours to our
properties, books, contracts, commitments, personnel and records. We further
agreed to furnish promptly to DDR and DDR Sub all other information concerning
our business, properties and personnel as they may reasonably request.

NO SOLICITATION

     In the merger agreement, we have agreed that, prior to the merger:

     - except as described below, neither we nor any of our subsidiaries will
       initiate, solicit or knowingly encourage, directly or indirectly, any
       acquisition proposal, or engage in any negotiations concerning or
       otherwise provide any confidential information or take any action
       designed or reasonably likely to facilitate any acquisition proposal;

     - except as described below, we will use our reasonable best efforts to
       cause our officers, trust managers, employees, agents and financial
       advisors not to engage in the activities listed in the preceding bullet
       point;

                                       62
   69

     - we will immediately cease and cause to be terminated any existing
       activities, discussions or negotiations with any parties conducted prior
       to November 1, 2000 with respect to the above actions; and

     - we will promptly notify DDR Sub if we receive any such inquiries or
       proposals, or any requests for information, or if any such negotiations
       or discussions are sought to be initiated or continued.

     The merger agreement does not prohibit our board of trust managers from:

     - furnishing information to, or engaging in discussions or negotiations
       with, any third party that makes an unsolicited acquisition proposal if:

      - the board determines, in good faith, following consultation with and
        after considering the advice of its legal and financial advisors, that
        these actions could reasonably be expected to result in a superior
        acquisition proposal; and

      - prior to furnishing information to, or engaging in discussions or
        negotiations with, the third party, we provide written notice to DDR and
        DDR Sub to the effect that we are furnishing information to, or entering
        into discussions with, that third party, and the status of the
        discussions or negotiations with the third party; or

     - if applicable, taking and disclosing to our shareholders a position, as
       contemplated by Rules 14d-9 and 14e-2 under the Securities Exchange Act
       of 1934, or making any disclosure to our shareholders with regard to an
       acquisition proposal.

     The board of trust managers may withdraw or modify its approval or
recommendation of the merger agreement only if it decides to approve and
recommend a superior acquisition proposal.

     The term "acquisition proposal" means an inquiry, proposal or offer with
respect to a transaction, other than the transactions contemplated by the sale
agreement or the merger agreement, involving, or any purchase of, all or any
significant portion of our assets or any of our equity securities or any assets
or securities of our subsidiaries. The term "superior acquisition proposal"
means a bona fide acquisition proposal:

     - that the board of trust managers (excluding DDR's designees), or an
       authorized committee of the board, determines to be more favorable to our
       shareholders from a financial point of view than the merger, based upon
       advice from our financial advisor and legal counsel that the value of the
       consideration provided for in the proposal is superior to the value of
       the consideration provided for in the merger; and

     - for which any required financing is then committed or which, in the good
       faith reasonable judgment of our board of trust managers and legal
       counsel, is reasonably capable of being financed by the third party, if
       financing is required.

        resulted in the failure of the merger to occur on or before May 31,
        2001;

        66 2/3% of the outstanding common shares; or

      - prior to the special meeting, our board of trust managers has withdrawn
        or modified, in any manner which is adverse to DDR, its recommendation
        or approval of the merger or the merger agreement or the board has

        proposal; or

      - AIP enters into a definitive agreement with respect to an acquisition

          recommendation or approval of the merger agreement or the board has
          approved or recommended a superior acquisition proposal.

TERMINATION FEES

     The merger agreement provides that, except as described below, all costs
and expenses incurred in connection with the merger agreement will be paid by
the party incurring the expense.

     - AIP must pay DDR $4.5 million if the merger agreement is terminated for
       any of the following reasons:

      - breach of any representation, warranty, covenant, obligation or
        agreement by AIP such that the conditions to closing cannot be satisfied
        by May 31, 2001;

      - failure to close the sale of the 31 properties to Value Enhancement Fund

       because DDR breaches any representation, warranty, covenant, obligation
       or agreement, such that the conditions to closing cannot be satisfied by
       May 31, 2000. If the sale agreement is terminated because of a breach by
       DDR, DDR will be responsible for any termination fee to be paid by AIP to
       Value Enhancement Fund under the property sale agreement.

INDEMNIFICATION

     The merger agreement provides that, from and after the time the merger
agreement becomes effective, AIP will indemnify our and our subsidiaries'
present and former officers, employees, directors and trust managers from
liabilities arising out of actions or omissions in their capacity as such prior
to or at the effective time of the merger, to the extent provided in our or our
subsidiaries' organizational documents or any written indemnification agreements
or other employee benefit plan or pension plan. In addition, AIP will maintain
directors' and officers' insurance coverage for six years after the effective
time of the merger on terms no less favorable to these indemnified parties than
existing insurance coverage. DDR has agreed to guarantee these obligations after
the merger is effective.

                                       66
   73

AMENDMENT

     The merger agreement may be amended at any time only by written agreement
of AIP, DDR and DDR Sub. However, after the required shareholder approval, no
term or condition contained in the merger agreement may be amended or modified
in any manner that by law requires further approval by our shareholders without
our obtaining this further shareholder approval.

                               FEES AND EXPENSES

     Whether or not the transactions are completed, all fees and expenses
incurred in connection with the merger will be paid by the party incurring the
expenses. If AIP terminates the property sale agreement, in addition to paying a
termination fee, AIP must reimburse Value Enhancement Fund for its verifiable
out-of-pocket costs, including legal fees, up to $450,000. In addition to any
termination fee and expenses that may become payable by AIP under the merger
agreement or the property sale agreement, AIP's estimated fees and expenses to
be incurred in connection with the proposed transactions are as follows:

                               DISSENTERS' RIGHTS

     The Texas REIT Act entitles any AIP shareholder who objects to the merger
and who follows the procedures set forth in the Texas REIT Act, instead of
receiving the consideration proposed under the merger, to receive cash equal to
the "fair value" of that shareholder's common shares of AIP. The following
summary of the procedures relating to the exercise of dissenters' rights is not
a complete statement of those rights and is qualified in its entirety by
reference to Sections 25.10, 25.20 and 25.30 of the Texas REIT Act, which are
reproduced in full as Appendix D attached to this proxy statement.

     ANY SHAREHOLDER CONTEMPLATING THE POSSIBILITY OF DISSENTING FROM THE MERGER
SHOULD CAREFULLY REVIEW THE TEXT OF APPENDIX D, PARTICULARLY THE SPECIFIC STEPS
REQUIRED TO PERFECT DISSENTERS' RIGHTS, AND SHOULD CONSULT HIS OR HER LEGAL
COUNSEL. DISSENTERS' RIGHTS WILL BE LOST IF THE PROCEDURAL REQUIREMENTS OF
SECTION 25.20 OF THE TEXAS REIT ACT ARE NOT FULLY AND PRECISELY FOLLOWED.

     AIP shareholders who follow the procedure set forth in Section 25.20 of the
Texas REIT Act are entitled to receive a cash payment equal to the fair value of
their common shares equaling the value of the shares on the day before the
meeting relating to the merger, excluding any appreciation or depreciation in
the value of the shares in anticipation of the proposed action. Unless all of
the procedures set forth in Section 25.20 of the Texas REIT Act are followed by
a shareholder who wishes to exercise dissenters' rights, that shareholder will
be bound by the terms of the merger. To be entitled to a cash payment upon
exercise of dissenters' rights, a shareholder must first file, before the
special meeting, with AIP a written notice objecting to the merger. This
objection must state that the shareholder will exercise the shareholder's right
to dissent if the merger is completed and must contain the shareholder's
address. A shareholder desiring to exercise that shareholder's dissenters'
rights must not vote in favor of adoption and approval of the merger agreement.
A vote against approval and adoption of the merger agreement, however, will not
in itself constitute a notice of intent to exercise dissenters' rights.

     After the merger has been approved by the AIP shareholders, AIP will send
to each shareholder who filed a notice indicating intent to exercise dissenters'
rights and did not vote in favor of the merger agreement, a notice that the
merger has been approved. This notice must be mailed within 10 days after
approval of the merger. The shareholder then has 10 days from the date AIP's
notice was delivered or mailed to the shareholder to make written demand on AIP
for payment of the fair value of the shareholder's shares. A shareholder who
fails to make a demand within the 10 day period is bound by the merger and will
receive the merger consideration.

     Within 20 days after receiving the shareholder's demand for fair value, AIP
must deliver or mail to the shareholder a written notice either stating that AIP
accepts the amount claimed in the demand and agrees to pay that amount within 90
days after the date on which the merger was effective or containing an estimate
by AIP of the fair value of the shares and an offer to pay the amount of that
estimate within 90 days after the date the merger was effective, subject to
receipt of notice from the shareholder that the shareholder agrees to accept the
amount of that estimate.

     If, within 60 days after the date on which the merger was effective, the
value of the shares is agreed on between the shareholder and AIP, then payment
for the shares will be made within 90 days after the date on which the merger
was effective. If, within that 60-day period, the shareholder and AIP do not
agree on the value of the shares, either the shareholder or AIP within 60 days
after the expiration of that 60-day period may file a petition in any court in
Dallas County, Texas asking for a finding and determination of the fair value of
the shareholder's shares.

     The court will then determine whether each dissenting shareholder has fully
complied with the provisions of Section 25.20 of the Texas REIT Act and,
therefore, has become entitled to the valuation of and payment of its shares.
The court will then appoint one or more qualified appraisers to determine the
value of the shares. Based on the appraisers' report, the court will determine
the fair value of the shares and will order AIP to pay that value, together with
interest on the value of the shares, beginning 91 days after the date on which
the merger was effective. Upon payment of the value of the shares as determined
by the court, the dissenting shareholders cease to have any interest in those
shares or in AIP.

                                       75
   82

     Any shareholder who has exercised dissenters' rights and demanded payment
for the shareholder's shares is not entitled to vote or exercise any of the
rights of a shareholder except the right to receive payment for the
shareholder's shares. Within 20 days after demanding payment for shares, each
holder of certificates representing those shares must submit the certificates to
AIP for notation on the certificate that demand for fair value has been made.
The failure of holders of certificated shares to submit the certificates to AIP,
at AIP's option, will terminate the shareholder's dissenters' rights. Any
shareholder who has demanded payment for the shareholder's shares may withdraw
that demand at any time before payment of those shares has been made or before
any petition has been filed with a court to determine fair value.


                  PROPOSAL NUMBER TWO: THE SALE OF PROPERTIES



GENERAL


     In order to facilitate the merger, we have entered into the sale agreement
with Value Enhancement Fund, under which we will sell 31 of our properties for
gross proceeds of $292.2 million. The closing of the sale of the properties to
Value Enhancement Fund is a condition to the closing of the merger. The cash
generated from the sale will be used to purchase the AIP common shares under the
merger agreement.

     THE APPROVAL OF THE HOLDERS OF AT LEAST 66 2/3% OF OUR OUTSTANDING COMMON
SHARES ON THE RECORD DATE IS REQUIRED TO APPROVE THIS PROPOSAL. IF USAA REALCO,
THE MORGAN STANLEY DEAN WITTER ENTITIES, DDR AND THE LASALLE ENTITIES VOTE THEIR
SHARES IN ACCORDANCE WITH THE VOTING AGREEMENTS THEY SIGNED, THIS PROPOSAL WILL
BE APPROVED. THE VOTING AGREEMENTS SIGNED BY THE LASALLE ENTITIES PROVIDE THAT
THEY MAY VOTE AGAINST THE PROPOSALS IF THEY BELIEVE THEY MUST DO SO TO SATISFY
THEIR FIDUCIARY DUTIES TO THEIR INVESTMENT ADVISORY CLIENTS. A MAJORITY OF OUR
TRUST MANAGERS NOT DESIGNATED BY DDR HAS APPROVED AND ADOPTED THE PROPERTY SALE
AGREEMENT IN CONNECTION WITH THE APPROVAL OF THE MERGER AGREEMENT AND BELIEVES
THAT THE TRANSACTIONS CONTEMPLATED BY THE PROPERTY SALE AGREEMENT IN THE CONTEXT
OF THE MERGER TRANSACTION ARE IN THE BEST INTERESTS OF OUR SHAREHOLDERS.
ACCORDINGLY, THESE TRUST MANAGERS RECOMMEND THAT SHAREHOLDERS VOTE FOR THIS
PROPOSAL.


FAIRNESS OF THE SALE OF PROPERTIES



     The special committee and the board of AIP have determined that the
consideration to be received by the AIP shareholders, other than DDR, in
connection with the merger is fair, from a financial point of view. The proceeds
from the sale of the properties constitute one of the components of the merger
consideration, as evaluated by the AIP trust managers. Because the special
committee evaluated the transaction as a whole, no separate analysis of the
benefits and detriments of the individual components of the merger consideration
or of the sale of properties standing alone was undertaken. Accordingly, in
order for you to evaluate the fairness of the overall transaction, including the
sale of the properties to Value Enhancement Fund, please review the information
provided under the captions entitled "Proposal Number One: The Merger; Special
Factors -- Recommendations of the Special Committee and the Board of Trust
Managers; Reasons for the Transactions" on page 40 and "-- Fairness of the
Merger; Opinion of the Financial Advisor" on page 44.



SALE AGREEMENT


     The closing of the transactions contemplated by the sale agreement will
take place immediately prior to the closing of the merger. The purchaser under
the sale agreement, Value Enhancement Fund, is a private investment fund managed
by Lend Lease, an institutional real estate advisor. Under the property sale
agreement, Value Enhancement Fund has the right to assign the agreement to one
or more assignees upon the following conditions:

     - the assignee is an entity controlling, controlled by or under common
       control with Value Enhancement Fund or an entity in which Value
       Enhancement Fund is a direct or indirect investor;

                                       76
   83

     - all of the earnest money has been delivered by Value Enhancement Fund in
       accordance with the purchase and sale agreement;

     - the assignee will assume all obligations under the purchase and sale
       agreement, but Value Enhancement Fund will remain primarily liable for
       the performance of the obligations;

     - Value Enhancement Fund will notify AIP promptly upon the designation of
       an assignee; and

     - a copy of the executed assignment and assumption agreement that will be
       delivered to AIP at least five days prior to the closing.

     In connection with the purchase of the properties, Value Enhancement Fund
will assume up to $149.947 million of debt and other liabilities associated with
the properties.

     Under the property sale agreement, we have agreed, among other things, to
the following:

     - obtaining approval of the AIP shareholders to the sale as soon as
       possible;

     - using our commercially reasonable efforts to sell our Manhattan Towers
       property for a purchase price of at least $48 million;

     - using our commercially reasonable efforts to cause the merger to occur
       contemporaneously with the sale of the properties; and

     - not to initiate or solicit any inquiries or negotiations with respect to
       a sale of all or any significant portion of our assets or those of our
       subsidiaries.

     We have satisfied the condition regarding Manhattan Towers.

     Our obligations and the obligations of Value Enhancement Fund to complete
the purchase and sale of the properties are subject to, among other things, the
following conditions:

     - each of the party's representations and warranties contained in the sale
       agreement being true and correct in all material respects as of the
       closing date;

     - Value Enhancement Fund's receipt of consent of lenders to its assumption
       of at least $118 million of the debt associated with the properties;

     - receipt by Value Enhancement Fund of estoppel certificates from nine of
       10 of our major tenants and from 75% of our other tenants;

     - receipt of approval of the AIP shareholders for the sale; and

     - compliance with all of the covenants and obligations contained in the
       sale agreement.

     We will be obligated to pay Value Enhancement Fund a termination fee of
$3.0 million and reimburse it for actual out-of-pocket expenses not to exceed
$450,000, if any of the following occurs and we elect to or are required to
terminate the sale agreement:

     - we are not able to obtain approval of our shareholders for the sale;

     - we are unable to cause the contemporaneous closing of the merger;

     - we receive a superior acquisition proposal, as determined in good faith
       by our board of trust managers; or

     - the sale of properties is not closed because the conditions described
       above are not satisfied as a result of our default.

The Special Committee
  of the Board of Trust Managers
American Industrial Properties REIT
6210 North Beltline, Suite 170
Irving, Texas 75063

Members of the Special Committee:

     You have informed us that American Industrial Properties REIT (the
"Seller"), Developers Diversified Realty Corporation ("Parent"), owner of
approximately 46% of the common shares of beneficial interest of the Seller, par
value $.10 per share ("Trust Common Shares"), and DDR Transitory Sub Inc.,
("Buyer"), a direct wholly-owned subsidiary of Parent, propose to enter into an
Agreement and Plan of Merger dated as of November 1, 2000 (the "Merger
Agreement") which provides, among other things, that a merger will occur between
the Buyer and the Seller in which Buyer will be merged with and into the Seller
(the "Merger"). Pursuant to the Merger Agreement, the shareholders of the Seller
(other than Buyer and any of its affiliates) will receive for each Trust Common
Share $13.74 in cash (the "Per Share Cash Consideration"), subject to adjustment
(i) downward for any distribution made or dividend paid by the Seller, to the
shareholders of the Seller, other than the Final Dividend (as defined in the
Merger Agreement) and (ii) upward if the Base Amount (as defined in the Merger
Agreement) is more than $1,000,000 greater than $173,564,000, determined in
accordance with Section 6.2(m) of the Merger Agreement. The shareholders of
Seller (other than Buyer and any of its affiliates) will be entitled to receive
a supplemental payment if Buyer sells all or substantially all of the DDR
Properties (as defined in the Merger Agreement), at any time during the first
six months following the Closing Date (as defined in the Merger Agreement), for
an amount greater than the agreed-upon aggregate values of the DDR Properties
set forth on Exhibit B to the Merger Agreement.

     You have also informed us that the Seller, AIP-Alfred, Inc. ("AIP-A"),
AIP/Battlefield GP, Inc. ("AIP/B"), AIP-SWAG Operating, L.P. ("AIP-S"), AIP
Properties #3, L.P. ("AIP-P") and AIP Operating, L.P. ("AIPO"; AIP-A, AIP/B,
AIP-S, AIP-P and AIPO, collectively, the "Seller Subs"), all wholly-owned
subsidiaries of the Seller and Value Enhancement Fund IV, L.P. ("Purchaser")
propose to enter into an Agreement of Purchase and Sale dated as of November 1,
2000 (the "Lend Lease Purchase Agreement") which provides, among other things,
for the sale (the "Lend Lease Sale") by the Seller and the Seller Subs to
Purchaser of the Property (as defined in the Lend Lease Purchase Agreement,
referred to herein as the "Lend Lease Portfolio") for not less than $135,400,000
cash consideration (net of related closing costs, repayment of indebtedness for
money borrowed secured by the Lend Lease Portfolio and related prepayment
penalties and fees) (the "Lend Lease Portfolio Consideration").

     You have also informed us that the Seller and Divco West Properties, LLC
("Manhattan Towers Purchaser") have entered into an Agreement of Purchase and
Sale dated August 16, 2000, as amended August 29, 2000, as further amended
September 21, 2000 (the "Manhattan Towers Purchase Agreement"; the Merger
Agreement, the Lend Lease Purchase Agreement and the Manhattan Towers Purchase
Agreement, collectively, the "Agreements") which provides, among other things,
for the sale (the "Manhattan Towers Sale"; the Lend Lease Sale and the Manhattan
Towers Sale, collectively, the "Real Estate Sale") by the Seller to Manhattan

Towers Purchase Agreement, referred to herein as the "Manhattan Towers"; the
Lend Lease Portfolio and the Manhattan Towers, collectively, the "Real Estate")
for not less than $34,200,000 cash consideration (net of related closing costs,
repayment of indebtedness for money borrowed secured by the Manhattan Towers and
related prepayment penalties and fees) (the "Manhattan Towers Consideration";
the Lend Lease Portfolio Consideration and the Manhattan Towers Consideration,
collectively, the "Aggregate Real Estate Consideration").

     You have also informed us that the consummation of the Merger is contingent
upon the consummation of the Real Estate Sale, provided that the Seller and the
Seller Subs, as applicable, receive the Aggregate Real Estate Consideration in
exchange for the Real Estate. In rendering this opinion, we assume that the Real
Estate Sale will be consummated and the Seller will receive the Aggregate Real
Estate Consideration.

     You have requested that we render our opinion as to the fairness, from a
financial point of view, to the holders of Trust Common Shares (other than Buyer
and any of its affiliates) of the Per Share Cash Consideration to be received by
such holders in the Merger.

     In arriving at the opinion set forth below, we have, among other things:

          (a) reviewed drafts of the Agreements in the forms provided to us,
     including the most recent drafts dated October 31, 2000 and have assumed
     that the final forms of such Agreements, as applicable, will not vary in
     any regard that is material to our analysis;

          (b) reviewed certain publicly available business and financial
     information we deemed relevant relating to the Seller and the industries in
     which the Seller operates;

          (c) reviewed certain internal non-public financial and operating data
     provided to us by the management of the Seller relating to the Seller's
     business, including certain forecast and projection information as to
     future financial results of such business;

          (d) discussed with members of the senior management of the Seller, the
     Seller's operations, historical financial statements and future prospects,
     before and after giving effect to the Merger and/or the Real Estate Sale,
     as well as such other matters as we deemed necessary or appropriate;

          (e) compared the financial and operating performance of the Seller
     with publicly available information concerning certain other companies and
     businesses we deemed reasonably comparable and reviewed the relevant stock
     market information for such other companies;

          (f) reviewed the financial terms of certain recent business
     combinations and acquisition transactions we deemed reasonably comparable
     to the Merger and the Real Estate Sale and otherwise relevant to our
     inquiry; and

          (g) made such other analyses and examinations as we have deemed
     necessary or appropriate.

     We have assumed and relied upon, without assuming any responsibility for
verification, the accuracy and completeness of all of the financial and other
information provided to, discussed with, or reviewed by or for us, or publicly
available, for purposes of this opinion and have further relied upon the
assurances of management of the Seller that they are not aware of any facts that
would make such information inaccurate or misleading. We have neither made nor
obtained any independent evaluations or appraisals of the assets or liabilities
of the Seller nor have we conducted a physical inspection of the properties and
facilities of the Seller. We have assumed that the financial forecast and
projection information provided to or discussed with us by or on behalf of the
Seller have been reasonably determined on bases reflecting the best currently
available estimates and judgments of the management of the Seller as to the
future financial

performance of such companies. We express no view as to such forecast or
projection information, or the assumptions upon which they were based.

     Our opinion herein is necessarily based on market, economic and other
conditions as they exist and can be evaluated on the date of this letter. Our
opinion is limited to the fairness, from a financial point of view, to the
holders of the Trust Common Shares (other than Buyer and any of its affiliates)
of the Per Share Cash Consideration to be received in the Merger and we express
no opinion as to the underlying decision by the Seller to engage in the Merger
or the Real Estate Sale. We also express no opinion on matters of a tax,
accounting or legal nature related to the Merger or the Real Estate Sale. This
opinion does not constitute a recommendation to any holder of equity interests
in the Seller as to how such holder should vote (or agree to vote) with respect
to the Merger.

     Chase Securities Inc., as part of its financial advisory business, is
continually engaged in the valuation of businesses and their securities in
connection with mergers and acquisitions and valuations for estate, corporate
and other purposes. We have acted as financial advisor to the Special Committee
of the Board of Trust Managers of the Seller in connection with the Merger and
will receive a fee from the Seller for our services, including for rendering
this opinion, payment of a significant portion of which is contingent upon the
consummation of the Merger and the Real Estate Sale. In addition, the Seller has
agreed to indemnify us for certain liabilities arising out of our engagement. As
we have previously advised you, The Chase Manhattan Corporation and its
affiliates, including Chase Securities Inc., in the ordinary course of business,
may have from time to time, provided, and in the future may continue to provide,
for customary compensation, commercial and investment banking services to the
Seller, Parent, Lend Lease Real Estate Investments, Inc. and their respective
affiliates, including serving as agent bank for the Lend Lease Real Estate
Investments, Inc. credit facility, serving as agent bank for the Lend Lease
Global Properties, SICAF, credit facility and serving as agent bank for the Lend
Lease (U.S.) Finance, Inc. credit facility. In the ordinary course of business,
we or our affiliates may trade in the debt and equity securities of the Seller
and Parent and their respective affiliates, for our own accounts and for the
accounts of our customers and, accordingly, may at any time hold a long or short
position in such securities.

     Based upon and subject to the foregoing, we are of the opinion, as of the
date hereof, that the Per Share Cash Consideration in the Merger is fair, from a
financial point of view, to the holders of Trust Common Shares (other than Buyer
and any of its affiliates).

     This opinion is for the use and benefit of the Special Committee of the
Board of Trust Managers of the Seller in its evaluation of the Merger and shall
not be used for any other purpose without the prior written consent of Chase
Securities Inc., provided that the Special Committee of the Board of Trust
Managers of the Seller may provide a copy of this opinion to the Board of Trust
Managers of the Seller and, provided further that, the Board of Trust Managers
of the Seller may rely upon this opinion in its evaluation of the Merger.

                                            Very truly yours,

                                            /s/ CHASE SECURITIES INC.

                          AGREEMENT AND PLAN OF MERGER

     THIS AGREEMENT AND PLAN OF MERGER (this "Agreement"), dated as of November
1, 2000, is among Developers Diversified Realty Corporation, an Ohio corporation
("Parent"), DDR Transitory Sub Inc., a Texas corporation ("Buyer"), and American
Industrial Properties REIT, a Texas real estate investment trust ("Seller").

                                   RECITALS:

     A. The Boards of Directors of Buyer and Parent and the Board of Trust
Managers of Seller (the "Board of Managers," and each individually, a "Board
Manager") consider it advisable, subject to the conditions and other provisions
contained herein, that Buyer shall merge with and into Seller (the "Merger").

     B. Upon the terms and conditions set forth herein, Buyer and Seller shall
execute Articles of Merger (collectively, the "Articles of Merger") in
substantially the form attached hereto as Exhibit "A" and shall file such
Articles of Merger in accordance with Texas law to effectuate the Merger.

     C. Seller has received a fairness opinion relating to the transactions
contemplated hereby as more fully described herein.

     D. Parent, Buyer and Seller desire to make certain representations,
warranties and agreements in connection with the transactions contemplated
hereby.

     E. Parent and Buyer are unwilling to enter into this Agreement unless,
contemporaneously with the execution and delivery of this Agreement, certain
institutional holders of Seller's issued and outstanding common shares of
beneficial interest, par value $0.10 per share ("Trust Common Shares"), enter
into agreements (the "Holders' Agreements") providing for certain actions
relating to the Trust Common Shares owned by them, and such holders have entered
into the Holders' Agreements.

     NOW, THEREFORE, in consideration of the premises and the representations,
warranties, covenants and agreements contained herein, the parties hereto hereby
agree as follows:

                                   ARTICLE 1

                                   THE MERGER

     1.1  The Merger.  Upon the terms and subject to the conditions of this
Agreement, and in accordance with Section 23.40 of the Texas Real Estate
Investment Trust Act (the "REIT Act"), Parent shall contribute all of its Trust
Common Shares into Buyer and then Buyer shall be merged with and into Seller,
with Seller as the surviving real estate investment trust (the "Surviving
Company"). The name of the Surviving Company will be American Industrial
Properties REIT.

     1.2  Closing.  The closing of the Merger (the "Closing") will take place on
the later of (i) January 31, 2001 or (ii) within two (2) business days after the
date on which the last to be satisfied of the conditions in Article 6 is
satisfied or waived, provided, however, if all of the conditions are satisfied
or waived prior to the Seller Shareholders Meeting (as defined below)
immediately following the meeting (the "Closing Date"), at the offices of Locke
Liddell & Sapp, 2200 Ross Avenue, Suite 2200, Dallas, Texas 75201, unless
another date and time or place is agreed to in writing by the parties.

     1.3  Effective Time.  As soon as practicable following the satisfaction or
waiver of the conditions set forth in Article 6, the parties shall execute and
file the Articles of Merger, in accordance with Texas law, and shall make all
other filings and recordings required under Texas law. The Merger shall become
effective at such time ("Effective Time") as the Articles of Merger are accepted
by both the County Clerk in Dallas County, Texas, and the Secretary of State of
the State of Texas, or at such time as Buyer and Seller shall agree should be
specified in the Articles of Merger (not to exceed thirty (30) days after

                                       B-7
   97

the Articles of Merger are accepted for record). Unless otherwise agreed, the
parties shall cause the Effective Time to occur on the Closing Date.

     1.4  Effect of Merger on Declaration of Trust and Bylaws.  The Third
Amended and Restated Declaration of Trust (the "Trust Declaration") of Seller
and the Fifth Amended and Restated Bylaws of Seller (the "Bylaws"), as in effect
immediately prior to the Effective Time, shall continue in full force and effect
after the Merger until further amended in accordance with applicable Texas law.

     1.5  Board of Managers and Officers.  The board of trust managers of the
Surviving Company shall consist of Scott A. Wolstein, James A. Schoff, Robert H.
Gidel and Albert T. Adams, and those persons shall continue to serve for the
balance of their unexpired terms or their earlier death, resignation or removal.
Seller shall cause all other members of the Board of Managers of Seller
immediately prior to the Effective Time to submit their resignations as Board
Managers on or prior to the Closing Date. Immediately prior to the Closing, all
officers of Seller shall resign and all officers and directors of all Seller
Subsidiaries shall resign.

     1.6  Effect on Shares.  Subject to Section 1.7, as of the Effective Time,
automatically by virtue of the Merger and without any action on the part of any
holder of the following securities or any party hereto:

     (a) Each common share, $0.01 par value, of Buyer (the "Buyer Shares")
issued and outstanding immediately prior to the Effective Time shall be
converted into one validly issued, fully paid and nonassessable Trust Common
Share of the Surviving Company (the "Surviving Company Shares"). Certificates
which, immediately prior to the Effective Time, represented Buyer Shares shall
thereafter be deemed to represent the same number of Surviving Company Shares.
The Surviving Company shall issue new certificates representing Surviving
Company Shares to the shareholders of Buyer on a pro rata basis in accordance
with their respective shares of Buyer upon surrender to the Surviving Company of
share certificates formerly representing Buyer Shares.

     (b) Each Trust Common Share issued and outstanding immediately prior to the
Effective Time and held by any direct or indirect Seller Subsidiary or in the
treasury of Seller, shall be canceled and retired and cease to exist. Each Trust
Common Share issued and outstanding immediately prior to the Effective Time and
held by Parent, Buyer or any of their respective direct or indirect subsidiaries
shall be contributed to Seller and become treasury shares of Seller, which shall
be canceled in accordance with the immediately preceding sentence.

     (c) Each Trust Common Share issued and outstanding immediately prior to the
Effective Time, other than those shares referred to in Section 1.6(b) and in
Section 1.7, shall, subject to Section 5.8, be converted automatically into the
right to receive $13.74 in cash (or such greater amount as determined in
accordance with the last paragraph of Section 6.2(m)) (the "Common
Consideration"). If Seller makes a distribution or pays to the holders of Trust
Common Shares or declares a dividend other than the Final Dividend (as defined
in Section 1.9(a)), the Common Consideration payable to holders of Trust Common
Shares in the Merger shall be reduced by the amount derived by dividing the
aggregate amount of such dividends and distributions by the number of Trust
Common Shares issued and outstanding immediately prior to the Effective Time
(including, without limitation, the Trust Common Shares held, directly or
indirectly, by Parent).

     (d) Each certificate previously representing Trust Common Shares, other
than shares referred to in Section 1.6(b) or in Section 1.7, shall thereafter
represent only the right to receive the Common Consideration in accordance with
Section 1.6(c) plus any declared but unpaid dividends on the shares represented
thereby. The holders of certificates previously representing Trust Common Shares
outstanding immediately prior to the Effective Time shall cease to have any
rights with respect to Trust Common Shares except as otherwise provided herein
or by law.

     1.7  Dissenters' Rights.  Notwithstanding anything in this Agreement to the
contrary, Trust Common Shares outstanding immediately prior to the Effective
Time and held by a holder who has not voted in favor of the Merger and who has
dissented from the Merger in accordance with Sections 25.10, 25.20
                                       B-8
   98

and 25.30 of the REIT Act ("Dissenting Shares") shall not be converted into the
right to receive the Common Consideration as provided in Section 1.6 and shall
not be entitled to any of the additional consideration provided for in Section
1.11, unless and until such holder fails to perfect or withdraws or otherwise
loses his right to payment under the REIT Act. If, after the Effective Time, any
such holder fails to perfect or withdraws or loses his right to such payment,
such Dissenting Shares shall thereupon be treated as if they had been converted
as of the Effective Time into the right to receive the Common Consideration, if
any, to which such holder is entitled, without interest thereon, and shall be
eligible to receive a pro rata portion of any additional consideration payable
under Section 1.11. Seller shall give Buyer prompt notice of any notice of
dissent received by Seller and, prior to the Effective Time, Buyer shall have
the right to participate in all negotiations and proceedings with respect to
such dissents. Prior to the Effective Time, Seller shall not, except with the
prior written consent of Buyer, make any payment with respect to, or settle or
offer to settle, any such dissents.

     1.8  Share Options and Related Matters.  Each option (collectively, the
"Seller Options") granted under the Seller's Employee and Trust Manager
Incentive Plan, as amended (the "Seller Incentive Plan"), to a person other than
Parent, which is outstanding (whether or not then exercisable) immediately prior
to the Effective Time and which has not been exercised or canceled prior
thereto, shall, at the Effective Time, be canceled and upon the surrender and
cancellation of the option agreement representing such Seller Option, the
Surviving Company shall pay to the holder thereof at the Closing, with respect
to each canceled option, cash in an amount equal to the amount by which the
Common Consideration exceeds the option exercise price. The cash payment shall
be treated as compensation and shall be net of any applicable federal or state
withholding tax (the "Option Consideration"). Seller shall pay at the Effective
Time, to each participant having a deferral account under Seller's Deferred
Compensation Plan for Non-Employee Trust Managers, cash in an amount equal to
the value of his deferral account.

     1.9  Exchange of Certificates; Pre-Closing Dividends; Fractional Shares.

     (a) From and after the Effective Time, Seller's transfer agent shall act as
exchange agent (the "Exchange Agent"). Immediately prior to the Effective Time,
(i) if the Closing occurs after the Anticipated Closing Date (as defined in
Section 6.2(m)), to the extent such dividend would not cause Seller to fail to
satisfy the condition set forth in Section 6.2(m), Seller shall have the right
to declare a dividend in the amount per share on each Trust Common Share issued
and outstanding immediately prior to the Effective Time (including, without
limitation, the Trust Common Shares held, directly or indirectly, by Parent)
equal to the amount of cash generated by operations during the period commencing
on the fourth day immediately following the Anticipated Closing Date and ending
at the close of business on the day immediately preceding the Closing Date (such
amount to be certified in writing to Parent and Buyer by Seller's Chief
Executive Officer and Chief Financial Officer) divided by the number of Trust
Common Shares issued and outstanding on the record date for such dividend or
distribution (including, without limitation, the Trust Common Shares held,
directly or indirectly, by Parent) (the "Final Dividend"), and shall deposit
with the Exchange Agent the aggregate amount required to pay the Final Dividend
on each Trust Common Share issued and outstanding immediately prior to the
Effective Time (including, without limitation, the Trust Common Shares held,
directly or indirectly, by Parent), and (ii) Seller, Buyer and Parent shall
deposit with the Exchange Agent, in accordance with the provisions of this
Section 1.9, the aggregate Common Consideration to be paid to Seller's
shareholders, excluding the holders of those shares referred to in Section
1.6(b) and in Section 1.7. The aggregate amount deposited by Seller and Buyer
under this Section 1.9(a) is sometimes referred to in this Agreement as the
"Exchange Fund." Seller shall fund the amount required to pay the Final Dividend
solely from the cash generated by operations described above and shall not fund
any portion of that amount, directly or indirectly, through borrowings. Seller
shall retain the net cash proceeds from the sale of the Manhattan Towers
Properties (except to the extent such proceeds must be distributed to
shareholders to prevent Seller from having to pay federal income tax) and the
Lend Lease Properties, and the Net Other Assets amounts for the deposit required
under clause (ii) above, and shall include those net cash proceeds in the
deposit made pursuant to clause (ii). If such deposited amounts are insufficient
to pay in full the Common Consideration, Parent will fund the deficiency or
Parent will cause the Surviving Company to fund such deficiency by drawing

                                       B-9
   99

down from the Surviving Company's available line of credit (any associated costs
to be borne by Parent and Buyer), and such amount as is necessary to cover any
deficiency shall be deposited with the Exchange Agent.

     (b) Promptly, and in any event within two (2) business days after the
Effective Time, Parent shall cause the Exchange Agent to mail to each holder of
record of a certificate that immediately prior to the Effective Time represented
Trust Common Shares ("Certificates") (except holders of those shares referred to
in Section 1.6(b) and in Section 1.7) (i) a letter of transmittal (the "Letter
of Transmittal") that shall specify that delivery shall be effected, and risk of
loss and title to the Certificates shall pass, only upon delivery of the
Certificates duly endorsed to the Exchange Agent and in such form and with such
other provisions as Parent may reasonably specify and (ii) instructions for use
in effecting the surrender of the Certificates and receiving the Final Dividend
(if any) and the Common Consideration in respect thereof. Upon surrender of a
Certificate to the Exchange Agent for cancellation together with such Letter of
Transmittal, duly executed and completed in accordance with the instructions
thereto, the holder of such Certificate shall be entitled to receive in exchange
therefor a check representing the amount of the Final Dividend (if any) and the
Common Consideration to which such holder shall be entitled, after giving effect
to any required withholding tax, and the Certificate so surrendered shall be
canceled forthwith. In the event of a transfer of ownership of Trust Common
Shares which is not registered in the transfer records of Seller, checks for the
Final Dividend (if any) and the Common Consideration to which the registered
holder shall be entitled may be issued and paid to the applicable transferee if
the Certificate representing such Trust Common Shares is presented to the
Exchange Agent, accompanied by all documents required to evidence and effect
such transfer and by evidence reasonably acceptable to the Exchange Agent that
any applicable stock transfer taxes have been paid. Immediately following the
Effective Time, the Exchange Agent shall (x) pay to the administrator of
Seller's Dividend Reinvestment Plan (the "DRIP") or to one or more persons
designated by such administrator, an amount equal to the product of (1) the
Final Dividend (if any) and the Common Consideration and (2) the number of Trust
Common Shares held in the DRIP as of the Effective Time, and (y) make
appropriate arrangements for the immediate payment of the Final Dividend (if
any) and the Common Consideration to the beneficial owners of any Trust Common
Shares that are held in book-entry or other electronic form and for which at the
Effective Time there is no Certificate representing the ownership thereof.

     (c) At and after the Effective Time, there shall be no transfers on the
stock transfer books of the Surviving Company of any Trust Common Shares which
were outstanding immediately prior to the Effective Time. If, after the
Effective Time, Certificates are presented to the Surviving Company, they shall
be canceled and exchanged for the Final Dividend (if any) and the Common
Consideration in accordance with this Section 1.9.

     (d) Any portion of the Exchange Fund (including the proceeds of any
investments thereof) that remains unclaimed by the former holders of Trust
Common Shares two (2) years after the Effective Time shall be delivered to the
Surviving Company. Any former holder of Trust Common Shares who has not
theretofore complied with this Article 1 shall thereafter look only to the
Surviving Company for payment of the Final Dividend (if any) and the Common
Consideration, as determined pursuant to this Agreement, without any interest
thereon. None of Parent, Buyer, Seller, the Exchange Agent or any other person
shall be liable to any former holder of Trust Common Shares for any amount
properly delivered to a public official pursuant to applicable abandoned
property, escheat or similar laws. If any Certificate shall have been lost,
stolen or destroyed, upon the making of an affidavit of that fact by the person
claiming such Certificate to be lost, stolen or destroyed and, if required by
the Surviving Company, the posting by such person of a bond in such reasonable
amount as the Surviving Company may direct as indemnity against any claim that
may be made against it with respect to such Certificate, the Exchange Agent or
the Surviving Company will issue and pay in exchange for such lost, stolen or
destroyed Certificate the Final Dividend (if any) and the Common Consideration.

     1.10  Right to Receive Dividends.  Notwithstanding anything in this
Agreement to the contrary, any holder of Trust Common Shares who, on the date of
the surrender of a Certificate, has not received any dividend or other
distribution with respect to such shares with a declared record date on or prior
to the
                                      B-10
   100

date of such surrender shall nevertheless be entitled to receive any such
dividend or distribution on the later of the date of such surrender or the
payment date of such dividend or distribution.

     1.11  Additional Merger Consideration.  If at any time during the first six
months following the Closing Date, Buyer sells all or substantially all of the
properties listed on Exhibit B hereto (the "DDR Properties") for a net amount
greater than the agreed-upon aggregate values of the DDR Properties set forth on
Exhibit B, then the Allocable Portion (as defined below) of such incremental
proceeds shall be paid into a trust created for the benefit of the Non-Parent
Shareholders (as defined below). The funds, if any, held in such trust shall be
distributed not later than nine months after the Closing Date to the Non-Parent
Shareholders on a pro rata basis in accordance with their respective holdings of
Trust Common Shares immediately prior to the Effective Time. "Allocable Portion"
means the amount derived by multiplying the amount of such incremental proceeds
from the sale of the DDR Properties by a fraction, the numerator of which is the
number of Trust Common Shares held by the Non-Parent Shareholders immediately
prior to the Effective Time and the denominator of which is the total number of
Trust Common Shares issued and outstanding immediately prior to the Effective
Time. "Non-Parent Shareholders" means all holders of Trust Common Shares
immediately prior to the Effective Time except for Parent, Buyer, any other
direct or indirect Parent subsidiary, and any holder of Trust Common Shares
entitled to payment therefor under the REIT Act in accordance with Section 1.7
hereof.

                                   ARTICLE 2

                    REPRESENTATIONS AND WARRANTIES OF SELLER

     Seller hereby represents and warrants to Parent and Buyer as follows:

     2.1  Organization and Qualification; Subsidiaries.

     (a) Seller is a real estate investment trust duly organized and validly
existing under the laws of the State of Texas. Seller has all requisite power
and authority to own, operate, lease and encumber its properties and carry on
its business as now conducted, and to enter into this Agreement and to perform
its obligations hereunder.

     (b) Each Subsidiary is a corporation, partnership or limited liability
company duly organized, validly existing and in good standing under the laws of
the jurisdiction of its incorporation or organization, and has the corporate,
partnership or limited liability company power and authority, as applicable, to
own its properties and carry on its business as it is now being conducted. As
used in this Agreement "Subsidiary" means each entity in which Seller owns any
direct or indirect equity interest.

     (c) Seller and each of the Subsidiaries is duly qualified to do business
and to the extent legally applicable is in good standing in such jurisdictions
in which the ownership of its property or the conduct of its business requires
such qualification, except for any jurisdiction in which any failure to be so
qualified or to be in good standing would not, individually or in the aggregate,
reasonably be expected to result in a Material Adverse Effect. As used in this
Agreement, "Material Adverse Effect" means a material adverse effect on the
financial condition, results of operations, business or prospects of Seller and
the Subsidiaries (to the extent of Seller's interests therein), taken as a
whole; provided, however, that any Action brought by a shareholder of Seller or
in the name of or on behalf of Seller relating to this Agreement, the Merger,
the sale by Seller of its Manhattan Towers Properties (the "Manhattan Towers
Transaction") or the transaction to be consummated pursuant to the Lend Lease
Agreement (as defined in Section 2.4 below) (the "Lend Lease Transaction") shall
be deemed not to have a Material Adverse Effect.

     (d) Schedule 2.1(d) sets forth the name of each Subsidiary (whether owned
directly or indirectly through one or more intermediaries). All of the
outstanding shares of capital stock of, or other equity interests in, each of
the Subsidiaries are duly authorized, validly issued, fully paid and
nonassessable, and are owned, directly or indirectly, by Seller free and clear
of all Liens, except as set forth in Schedule 2.1(d).  As used in this
Agreement, "Liens" means all liens, mortgages, deeds of trust, deeds to secure

encumbrances of any nature

                                      B-11

other interest holders, if any, in the Subsidiary; and (iii) any loans from
Seller to, or payments payable to Seller from, the Subsidiary, and the rate of

     2.2  Authority Relative to Agreements; Board Approval.

     (a) The execution, delivery and performance of this Agreement and of all of
the documents and instruments delivered in connection herewith by Seller are
within Seller's power. Subject to the receipt of the requisite approval of
Seller's shareholders and assuming this Agreement and such other documents and
instruments constitute binding obligations of Buyer and Parent, this Agreement
is, and the other documents and instruments required to be entered into
hereunder will be, when executed and delivered by Seller, the valid and binding
obligations of Seller, enforceable against Seller in accordance with their
respective terms subject only to bankruptcy, insolvency, reorganization,
moratorium or similar laws at the time in effect affecting the enforceability or
right of creditors generally and to general equitable principles (regardless of
whether such enforceability is considered in a proceeding in equity or at law).

     (b) A majority of the Board of Managers not designated by Parent has
approved and declared advisable this Agreement and the transactions contemplated
hereby in accordance with Texas law, and has determined to recommend that the
shareholders of Seller vote in favor of and approve the Merger.

     (c) Neither the consummation of the Merger pursuant to this Agreement, nor
(i) consummation of the transactions contemplated by the Lend Lease Transaction
or (ii) consummation of the transactions contemplated by the Manhattan Towers
Transaction, will give any person the right to demand payment for that
shareholder's shares under the laws of the State of Texas, under the Trust
Declaration, or otherwise, except for holders of Trust Common Shares who dissent
from the Merger pursuant to and in accordance with the REIT Act.

     2.3  Capital Stock.

     (a) Seller's authorized capital stock on the date hereof consists of
500,000,000 Trust Common Shares, and 50,000,000 preferred shares of beneficial
interest, $0.10 par value. As of the date hereof, there are 20,992,195 Trust
Common Shares issued and outstanding, and no preferred shares issued and
outstanding. All such issued and outstanding Trust Common Shares are duly
authorized, validly issued, fully paid, nonassessable and free of preemptive
rights except those granted by contracts identified on Schedule 2.3(a). Seller
has no outstanding bonds, debentures, notes or other obligations the holders of
which have the right to vote (or which are convertible into or exercisable for
securities the holders of which have the right to vote) with the shareholders of
Seller on any matter. Other than (i) the limited partnership units ("Partnership
Units") described in Schedule 2.3(a) to this Agreement which may be put to
Seller or any Subsidiary by the holders thereof for Trust Common Shares or the
cash equivalent thereof (at the option of Seller), (ii) options subject to grant
under the option plans described in Schedules 2.3(a) and (b)of this Agreement,
or (iii) as described in Schedule 2.3(c) to this Agreement, there are no
existing options, warrants, calls, subscriptions, convertible securities, or
other rights, agreements or commitments which obligate Seller or any Subsidiary
to issue, transfer or sell any shares of capital stock or other equity interests
of Seller.

     (b) Except as described in Schedule 2.3(a), no Subsidiary has issued
Partnership Units or granted securities convertible into interests in Seller or
in any Subsidiary and no Subsidiary is a party to any outstanding commitment of
any kind relating to, or any presently effective agreement or understanding with
respect to, interests in Seller or in any Subsidiary, whether issued or
unissued.

     (c) Except for Seller's interests in the Subsidiaries or as described in
Schedule 2.1(d), none of Seller or any of the Subsidiaries owns directly or
indirectly any interest or investment (whether equity or debt) in any
corporation, partnership, joint business, trust or other legal entity (other
than investments in short-term investment securities).

                                      B-12
   102

     2.4  No Conflicts; No Defaults; Required Filings and Consents.  Neither the
execution and delivery by Seller of this Agreement, the agreement among Lend
Lease Real Estate Investments, Inc., Seller and certain of Seller's Subsidiaries
(the "Lend Lease Agreement") and the agreement relating to the sale of the
Manhattan Towers property ("the Manhattan Towers Agreement"), nor the
consummation by Seller of the transactions contemplated hereby and thereby in
accordance with the terms hereof and thereof, will:

     (a) conflict with or result in a breach of any provision of the Trust
Declaration or Bylaws;

     (b) except as described in Schedule 2.4(b), result in a breach or violation
of, a default under, or the triggering of any payment or other obligation
pursuant to, or accelerate vesting under, any tax protection agreement or other
agreement to which Seller or any Subsidiary is a party or by which Seller or any
Subsidiary is otherwise bound, or any Seller or Subsidiary stock option plan,
option plan or similar compensation plan or any grant or award made under any of
the foregoing;

     (c) violate or conflict with any statute, regulation, judgment, order,
writ, decree or injunction applicable to Seller or to any of the Subsidiaries;

     (d) except as described in Schedule 2.4(d), violate or conflict with or
result in a breach of any provision of, or constitute a default (or any event
which, with notice or lapse of time or both, would constitute a default) under,
or result in the termination or in a right of termination or cancellation of, or
accelerate the performance required by, or result in the creation of any Lien
upon any of the properties of Seller or of any of the Subsidiaries under, or
result in being declared void, voidable or without further binding effect, any
of the terms, conditions or provisions of any note, bond, mortgage, indenture,
deed of trust or any franchise, permit, lease, contract, agreement or other
instrument, commitment or obligation to which Seller or any of the Subsidiaries
is a party, or by which Seller or any of its Subsidiaries or any of their
properties is bound or affected; or

     (e) require any consent, approval or authorization of, or declaration,
filing or registration with, any Government Authority (as defined below), other
than the Articles of Merger pursuant to Section 1.3 hereof and any filings
required under the Securities Act of 1933, as amended (the "Securities Act"),
the Securities Exchange Act of 1934, as amended (the "Exchange Act"), the
Hart-Scott-Rodino Antitrust Improvements Act of 1976 (the "HSR Act"), state
securities laws ("Blue Sky Laws") (collectively, the "Filings"), and any filings
required to be made with the Texas State Department of Assessments and Taxation,
if any, or any national securities exchange on which the Trust Common Shares are
listed.

     2.5  SEC Matters and Absence of Undisclosed Liabilities.

     (a) Seller has delivered or made available to Parent and Buyer the Annual
Report on Form 10-K for the fiscal year ended December 31, 1999 filed by Seller
with the Securities and Exchange Commission ("SEC") and all exhibits, amendments
and supplements thereto, including all documents incorporated by reference
therein (collectively, the "Form 10-K"), and each registration statement,
report, proxy statement or information statement and all exhibits thereto
prepared by Seller or relating to the Properties (as defined in Section 2.11(a))
for filing in the three (3) years ending on the date of this Agreement, each in
the form (including exhibits and any amendments thereto) filed with the SEC
(collectively the "Seller Reports"). The Seller Reports were filed with the SEC
in a timely manner and constitute all forms, reports and documents required to
be filed by Seller under the Securities Act and the Exchange Act and the rules
and regulations promulgated thereunder (the "Securities Laws"). As of their
respective dates and as amended through the date of this Agreement, the Seller
Reports (other than preliminary materials), (i) complied as to form in all
material respects with the applicable requirements of the Securities Laws and
(ii) did not contain any untrue statement of a material fact or omit to state a
material fact required to be stated therein or necessary to make the statements
made therein, in the light of the circumstances under which they were made, not
misleading except to the extent such statements have been modified or superseded
by later filed Seller Reports. To Seller's knowledge, there is no unresolved
violation asserted by any Government Authority with respect to any of the Seller
Reports. As used in this Agreement, "Government Authority" means any government
or state (or any subdivision thereof) of or in the United

                                      B-13
   103

States, or any agency, authority, bureau, commission, department or similar body
or instrumentality thereof, or any government court or tribunal.

     (b) Each of Seller's balance sheets included in or incorporated by
reference into the Seller Reports (including the related notes and schedules)
fairly presented the financial position of Seller as of its date and each of the
statements of operations, shareholders' equity (deficit) and cash flows included
in or incorporated by reference into the Seller Reports (including any related
notes and schedules) fairly presented the results of operations, retained
earnings or cash flows, as the case may be, of Seller for the period covered
thereby, in each case in accordance with United States generally accepted
accounting principles ("GAAP") consistently applied during the periods involved
and in accordance with Regulation S-X promulgated by the SEC, except as may be
noted therein and except, in the case of the unaudited statements, for normal
recurring year-end adjustments which would not, individually or in the
aggregate, reasonably be expected to result in a Material Adverse Effect.

     (c) Except as and to the extent set forth in the Seller Reports or in any
Schedule hereto, to Seller's knowledge, none of Seller or any of the
Subsidiaries has any material Liabilities, nor do there exist any circumstances
that would, individually or in the aggregate, reasonably be expected to result
in a Material Adverse Effect. As used in this Agreement, "Liabilities" means, as
to any person, all debts, adverse claims, liabilities and obligations, direct,
indirect, absolute or contingent of such person, whether accrued, vested or
otherwise, whether in contract, tort, strict liability or otherwise and whether
or not actually reflected, or required by GAAP to be reflected, in such person's
balance sheets or other books and records, including (i) obligations arising
from noncompliance with any law, rule or regulation of any Government Authority
or imposed by any court or any arbitrator of any kind, (ii) all indebtedness or
liability of such person for borrowed money, or for the purchase price of
property or services (including trade obligations), (iii) all obligations of
such person as lessee under leases, capital or other, (iv) liabilities of such
person in respect of plans covered by Title IV of ERISA, or otherwise arising in
respect of plans for employees or former employees or their respective families
or beneficiaries, (v) reimbursement obligations of such person in respect of
letters of credit, (vi) all obligations of such person arising under acceptance
facilities, (vii) all liabilities of other persons or entities, directly or
indirectly, guaranteed, endorsed (other than for collection or deposit in the
ordinary course of business) or discounted with recourse by such person or with
respect to which such person is otherwise directly or indirectly liable, (viii)
all obligations secured by any Lien on property of such person, whether or not
the obligations have been assumed, and (ix) all other items which have been, or
in accordance with GAAP would be, included in determining total liabilities on
the liability side of such person's balance sheet.

     2.6  Litigation; Compliance With Law.

     (a) Except as disclosed in Schedule 2.6(a), there is no action, suit,
arbitration, inquiry, proceeding or investigation by or before any Government
Authority (any such item, an "Action") pending or, to Seller's knowledge,
threatened against Seller or any of the Subsidiaries that would, individually or
in the aggregate, reasonably be expected to result in a Material Adverse Effect,
or which questions the validity of this Agreement, the Lend Lease Agreement or
the Manhattan Towers Agreement or of any action taken or to be taken in
connection herewith or therewith. Except as disclosed in Schedule 2.6(a), there
are no continuing orders, injunctions or decrees of any Government Authority to
which Seller or any of the Subsidiaries is a party or by which any of its
properties or assets are bound.

     (b) None of Seller or any of the Subsidiaries is in material violation of
any statute, rule, regulation, order, writ, decree or injunction of any
Government Authority or any body having jurisdiction over them or any of their
respective properties which, if enforced, would, individually or in the
aggregate with all other such violations, reasonably be expected to result in a
Material Adverse Effect.

     2.7  Absence of Certain Changes or Events.  Except as disclosed in Schedule
2.7 or in any Seller Report, since June 30, 2000, Seller and each of the
Subsidiaries has conducted its business only in the ordinary course of such
business and has not acquired any real estate or entered into any financing
arrangements in connection therewith, and there has not been (a) any change,
circumstance or event that would reasonably be expected to result in a Material
Adverse Effect, (b) any declaration, setting aside or
                                      B-14
   104

payment of any dividend or other distribution with respect to the Trust Common
Shares, (c) any commitment, contractual obligation, borrowing, capital
expenditure or transaction (each, a "Commitment") entered into by Seller or any
of the Subsidiaries, other than Commitments which would not, individually or in
the aggregate, be expected to result in a Material Adverse Effect, (d) any
change in Seller's accounting principles, practices or methods, (e) any
increases by Seller in any bonuses, salaries or other compensation paid or
payable to any holder of Trust Common Shares, Board Manager, officer or
employee, or (f) any adoption of, or increase in benefits or amounts payable
under, any Plan.

     2.8  Tax Matters; REIT and Partnership Status.

     (a) Seller and each of the Subsidiaries has timely filed with the
appropriate taxing authority all tax returns required to be filed by it or has
timely requested extensions and any such request has been granted and has not
expired. Each such tax return is complete and accurate in all material respects.
All information shown on any such tax return is correct in all material
respects, and all material Taxes shown as owed by Seller or by any of the
Subsidiaries on any tax return have been paid or accrued, except for Taxes
contested in good faith and for which adequate reserves have been taken. As used
in this Agreement, "Tax" means any federal, state, local, or foreign income,
gross receipts, license, payroll, employment, excise, severance, stamp,
occupation, premium, windfall profits, environmental (including taxes under Code
(as defined below) Section 54A), customs duties, capital stock, profits,
withholding, social security (or similar), unemployment, disability, real
property, personal property, sales, use, transfer, registration, value added,
alternative or add-on minimum, estimated, or other tax of any kind whatsoever,
including any interest, penalty or addition thereto, whether disputed or not.
Each of Seller and each of the Subsidiaries has properly accrued all Taxes for
periods subsequent to the periods covered by such tax returns as required by
GAAP. None of Seller or any of the Subsidiaries has executed or filed with the
Internal Revenue Service (the "IRS") or any other taxing authority any agreement
now in effect extending the period for assessment or collection of any Tax. None
of Seller or any of the Subsidiaries is a party to any pending action or
proceeding by any taxing authority for assessment or collection of any Tax, and
no claim for assessment or collection of any Tax has been asserted against it.
No claim has been made by any authority in a jurisdiction where Seller or any of
the Subsidiaries does not file tax returns that it is or may be subject to
taxation or reporting in that jurisdiction. There is no dispute or claim
concerning any information, reporting or tax liability of Seller or of any of
the Subsidiaries, (i) claimed or raised by any taxing authority in writing or
(ii) as to which Seller or any of the Subsidiaries has knowledge. Seller is a
"domestically controlled" REIT within the meaning of Section 897(h)(4)(B) of the
Internal Revenue Code of 1986, as amended (the "Code"), and to Seller's
knowledge, there are no nondomestic registered beneficial owners of Trust Common
Shares. To Seller's knowledge, no person or entity which would be treated as an
"individual" for purposes of Section 542(a)(2) of the Code (as modified by
Section 856(h) of the Code) owns or would be considered to own (taking into
account the ownership attribution rules under Section 544 of the Code, as
modified by Section 856(h) of the Code) in excess of 9.8% of the value of the
outstanding equity interests in Seller.

     (b) Seller (i) made a valid election in its federal income tax return for
the tax year ended December 31, 1993 to be taxed as a real estate investment
trust within the meaning of Section 856 of the Code ("REIT") and has complied in
all material respects (and will comply in all material respects) with all
applicable provisions of the Code relating to a REIT, for 1993 through the date
hereof, (ii) has operated, and will to continue to operate, in such a manner as
to qualify as a REIT for 2000 and up to the Effective Time, (iii) has not taken
or omitted to take any action which would reasonably be expected to result in a
challenge to its status as a REIT, and, no such challenge is pending or
threatened, and (iv) to its knowledge, will not be rendered unable to qualify as
a REIT for federal income tax purposes as a consequence of the transactions
contemplated by this Agreement.

     (c) Except as described in Schedule 2.8(c), no amount or other entitlement
that could be received (whether in cash or property or the vesting of property)
as a result of or in connection with any of the transactions contemplated hereby
by any employee, officer, or manager of Seller or of any of the Subsidiaries or
of any of their affiliates (as defined in Rule 12b-2 promulgated under the
Exchange Act; hereinafter, "Affiliates") who is a "disqualified individual" (as
such term is defined in proposed Treasury
                                      B-15
   105

Regulation Section 1.280G-1) under any employment, severance or termination
agreement, other compensation arrangement or plan currently in effect would be
characterized as an "excess parachute payment" (as such term is defined in
Section 280G(b) of the Code).

     (d) Except as described in Schedule 2.8(d), the disallowance of a deduction
under Section 162(m) of the Code for employee remuneration will not apply to any
amount paid or payable by Seller or by any of the Subsidiaries under any
contract, stock plan, program, arrangement or understanding currently in effect.

     (e) Each Subsidiary organized as a partnership or limited liability company
(and any other Subsidiary that files tax returns as a partnership for federal
income tax purposes) was and, as of the date hereof, continues to be, and will
continue to be through the Closing Date, classified as a partnership or as a
disregarded entity for federal income tax purposes. Neither Seller nor any
Subsidiary holds any asset the disposition of which would be subject to rules
similar to (i) Section 1374 of the Code as the result of Internal Revenue
Service Notice 88-19, or (ii) those contained in proposed regulations issued
under Treasury Regulation Section 1.337(d)-5, or temporary regulations issued
under Treasury Regulation Section 1.337(d)-5T, if such regulations were
finalized in the form proposed.

     (f) For each taxable year beginning with Seller's taxable year that ended
December 31, 1993, the dividends paid by Seller on the Trust Common Shares have
been and will continue to be paid pro rata, with no preference to any Trust
Common Share as compared with other shares.

     (g) Seller has not actively conducted a business (i) from which it earns
fees for services it performs and (ii) that would cause (x) Seller's REIT status
to be lost or (y) rents from real property to be treated as not rent under the
Code.

     (h) As required by Treasury Regulation Section 1.857-8, Seller has
maintained the necessary records regarding the actual ownership of its shares,
and has timely made (i.e., by January 30 of each calendar year) the requisite
information requests of its shareholders regarding share ownership and has
maintained a list of the persons failing or refusing to comply in whole or in
part with Seller's demand for statements regarding share ownership.

     (i) Seller has never owned more than 10% of the voting common shares of any
corporation other than a "Qualified REIT Subsidiary," i.e., (i) before 1998, a
corporation, all of whose shares were owned by Seller at all times during such
corporation's existence, and (ii) after January 1, 1998, a corporation (x) all
of whose shares are owned by Seller, and (y) all of whose earnings and profits
existing at the time Seller acquired all of its shares are distributed before
the end of the tax year in which all of the shares are acquired.

     2.9  Compliance with Agreements.

     (a) Seller is not in default under or in violation of the Declaration of
Trust or the Bylaws and neither Seller nor any of the Subsidiaries is in default
under or in violation of any material provision of the respective charter,
bylaws, partnership agreement, operating agreement or any similar organizational
document of such Subsidiaries.

     (b) Since January 1, 1997, each of Seller and each of the Subsidiaries has
filed all reports, registrations and statements, together with any amendments
required to be made with respect thereto, that it was required to file with any
Government Authority and all other reports and statements required to be filed
by it, including any report or statement required to be filed pursuant to the
laws, rules or regulations of the United States, and has paid all fees or
assessments due and payable in connection therewith. There is no unresolved
violation asserted by any regulatory agency of which Seller has received any
written notice which, if resolved in a manner unfavorable to Seller or any
Subsidiary, would, individually or in the aggregate with all other such
violations, reasonably be expected to result in a Material Adverse Effect.

     (c) Schedule 2.9(c) sets forth (i) a description of all material
indebtedness of Seller and of each of the Subsidiaries, whether unsecured or
secured or collateralized by mortgages, deeds of trust or other security
interests in the Property (as defined in Section 2.11(a)) or any other assets of
Seller or of any
                                      B-16
   106

Subsidiary, or otherwise and (ii) each Commitment currently in effect entered
into by Seller or by any of the Subsidiaries (including any guarantees of any
third party's debt or any obligations in respect of letters of credit issued for
Seller's or any Subsidiary's account) which may result in total payments or
liability in excess of $100,000, excluding Commitments that are terminable on
thirty (30) days or less notice, and excluding Commitments the breach of which
would not, individually or in the aggregate with all other such breaches,
reasonably be expected to result in a Material Adverse Effect. Neither Seller
nor any of the Subsidiaries is in default, and, to Seller's knowledge, no event
has occurred which, with the giving of notice or the lapse of time or both,
would constitute a default, under any of the documents described in clause (i)
or (ii) of the first sentence of this paragraph or in respect of any payment
obligations thereunder. All joint venture and partnership agreements to which
Seller or any of the Subsidiaries is a party as of the date hereof are described
in Schedule 2.9(c), all of which are in full force and effect as against Seller
or the applicable Subsidiary and, to Seller's knowledge, as against the other
parties thereto, and none of Seller or any of the Subsidiaries is in default,
and, to Seller's knowledge, no event has occurred which, with the giving of
notice or the lapse of time or both, would constitute a default, with respect to
any obligations thereunder, except as would not, individually or in the
aggregate with all other such defaults, reasonably be expected to result in a
Material Adverse Effect. To Seller's knowledge, the other parties to such
agreements are not in breach of any of their respective obligations thereunder,
except as would not, individually or in the aggregate with all other such
defaults, reasonably be expected to result in a Material Adverse Effect. To
Seller's knowledge, there is no condition with respect to any of the
Subsidiaries (including with respect to the partnership agreements for the
Subsidiaries that are partnerships) that would, individually or in the aggregate
with all other such conditions, reasonably be expected to result in a Material
Adverse Effect.

     (d) Except as disclosed in any other Schedule hereto, Schedule 2.9(d) sets
forth a complete and accurate list of all material agreements to which Seller or
any of the Subsidiaries is a party as of the date hereof relating to the
development or construction of, additions or expansions to, or management or
leasing services for, light industrial properties or office buildings or other
real properties which are currently in effect and under which Seller or any of
the Subsidiaries currently has, or expects to incur, any material obligation.

     (e) Except for (i) agreements made in the ordinary course of business with
a maturity of less than one (1) year or that are terminable on thirty (30) days
or less notice, and (ii) agreements the breach or nonfulfillment of which would
not, individually or in the aggregate with all other such breaches or
nonfulfillments, reasonably be expected to result in a Material Adverse Effect,
Schedule 2.9(e) sets forth a complete and accurate list of all material
agreements to which Seller or any Subsidiary is a party as of the date hereof
which are not listed in any other Schedule hereto and are not exhibits to any
filing made by Seller with the SEC. Each of the Lend Lease Agreement, the
Manhattan Towers Agreement and each agreement listed on Schedule 2.9(e) is in
full force and effect as against Seller and, to Seller's knowledge, as against
the other parties thereto, no payments, if any, are delinquent, no notice of
default thereunder has been sent or received by Seller or any of the
Subsidiaries, and, to Seller's knowledge, no event has occurred which, with
notice or lapse of time or both, would constitute such a default thereunder,
except for any such default that would not, individually or in the aggregate
with all other such defaults, reasonably be expected to result in a Material
Adverse Effect.

     (f) Seller has no written policies regarding transactions with Affiliates.
Schedule 2.9(f) lists all existing agreements with Affiliates relating to
matters other than employment or severance, each of which employment or
severance agreement is listed on Schedule 2.13(a).

     2.10  Financial Records; Trust Declaration and Bylaws; Corporate Records.

     (a) The books of account and other financial records of Seller and of each
of the Subsidiaries are in all material respects true and complete, have been
maintained in accordance with good business practices, and are accurately
reflected in all material respects in the financial statements included in the
Seller Reports.

                                      B-17
   107

     (b) Seller has delivered or made available to Buyer true and complete
copies of the Trust Declaration and the Bylaws, as amended to date, and the
charter, bylaws, organizational documents, partnership agreements and joint
venture agreements of the Subsidiaries, and all amendments thereto. All such
documents are listed on Schedule 2.10(b).

     (c) The minute books and other records of corporate, trust or partnership
proceedings of Seller and of each of the Subsidiaries contain accurate records
of all meetings of the equity holders, managers and other governing bodies
thereof and accurately reflect in all material respects all other corporate
action of the managers, shareholders and directors and any committees of the
Board of Managers and of the Subsidiaries which are corporations and all actions
of the partners of the Subsidiaries which are partnerships.

     2.11  Properties.

     (a) Schedule 2.11(a) sets forth a complete and accurate list and the
address of all real property owned or leased by Seller or by any of the
Subsidiaries or otherwise used by Seller or by any of the Subsidiaries in the
conduct of their business or operations. That real property, together with the
land at each address referenced in Schedule 2.11(a) and all buildings,
structures and other improvements and fixtures located on or under such land and
all easements, rights and other appurtenances to such land shall be referred to
individually as a "Property" and collectively as the "Properties." Seller, or,
in the case of properties owned by Subsidiaries, the Subsidiary or trustees
holding legal title solely for the benefit of a Subsidiary indicated in Schedule
2.11(a), owns good and indefeasible fee simple title (or, if so indicated in
Schedule 2.11(a), leasehold title) to each of the Properties, in each case free
and clear of any Liens, title defects, common restrictions or covenants, laws,
ordinances or regulations affecting use or occupancy (including zoning
regulations and building codes) or reservations of interests in title
(collectively, "Property Restrictions"), except for (i) Permitted Liens, (ii)
Property Restrictions imposed or promulgated by law or by any Government
Authority which are customary and typical for similar properties, and (iii) the
obligations relating to the properties identified as Lend Lease Properties on
Schedule 2.11(a) (the "Lend Lease Properties") arising under the Lend Lease
Agreement and the obligations relating to the properties identified as Manhattan
Towers Properties on Schedule 2.11(a) (the "Manhattan Towers Properties")
arising under the Manhattan Towers Agreement. As used in this Agreement,
"Permitted Liens" means (u) Liens (other than Liens imposed under ERISA or any
Environmental Law or in connection with any Environmental Claim) for taxes or
other assessments or charges of Governmental Authorities that are not yet
delinquent or that are being contested in good faith by appropriate proceedings
in each case, and with respect to which adequate reserves or other appropriate
provisions are being maintained by Seller or the Subsidiaries to the extent
required by GAAP, (v) statutory Liens of landlords, carriers, warehousemen,
mechanics, materialmen and other Liens (other than Liens imposed under ERISA or
any Environmental Law or in connection with any Environmental Claim) imposed by
law and created in the ordinary course of business for amounts not yet overdue
or which are being contested in good faith by appropriate proceedings, and in
each case with respect to which adequate reserves or other appropriate
provisions are being maintained by Seller or the Subsidiaries to the extent
required by GAAP and which do not exceed $25,000 in the aggregate, (w) the
Leases, (x) easements, rights-of-way and covenant restrictions which are
customary and typical for properties similar to the Properties and which do not
(1) interfere materially with the ordinary conduct of any Property or the
business of Seller and the Subsidiaries as a whole or (2) detract materially
from the value or usefulness of the Property to which they apply, (y) the Liens
which were granted by Seller or any of the Subsidiaries to lenders pursuant to
credit agreements in existence on the date hereof which are described in
Schedule 2.9(c), and (z) such imperfections of title and encumbrances, if any,
as would not individually or in the aggregate reasonably be expected to result
in a Material Adverse Effect. To Seller's knowledge, none of the Permitted Liens
interferes with, impairs, or is violated by the present use, occupancy or
operation (or if applicable, development) of any Property that is not included
in the Lend Lease Properties or in the Manhattan Towers Properties (the
Properties not included in the Lend Lease Properties or the Manhattan Towers
Properties, the "Buyer Properties") and none of the Property Restrictions
interferes with, impairs, or is violated by, the existence of any building or
other structure or

                                      B-18
   108

improvement which constitutes a part of, or the present use, occupancy or
operation (or, if applicable, development) of, any Buyer Property, except, in
each such case, to the extent that any interference, impairment or violation
would not, individually or in the aggregate with all other such items,
reasonably be expected to have a Material Adverse Effect. American Land Title
Association policies of title insurance (or marked title insurance commitments
having the same force and effect as title insurance policies) have been issued
by national title insurance companies insuring the fee simple or leasehold, as
applicable, title of Seller or a Subsidiary or a trustee holding legal title
solely for the benefit of a Subsidiary, as applicable, to each of the Buyer
Properties in amounts at least equal to the original cost thereof, subject only
to Permitted Liens, and to Seller's knowledge, all such policies are valid and
in full force and effect and no claim has been made under any such policy.

     (b) Except as described in Schedule 2.11(b), Seller has no knowledge (i)
that any currently required certificate, permit or license (including building
permits and certificates of occupancy for tenant spaces) from any Government
Authority having jurisdiction over any Property or any agreement, easement or
other right that is necessary to permit the lawful use, occupancy or operation
of the existing buildings, structures or other improvements that constitute a
part of any of the Properties or which are necessary to permit the lawful use
and operation of any existing driveways, roads or other areas of ingress and
egress to and from any of the Properties has not been obtained or is not in full
force and effect, or of any pending threat of modification or cancellation of
any of same, or (ii) of any violation by any Property of any federal, state or
municipal law, ordinance, order, regulation or requirement, including any
applicable zoning law or building code, arising from the use or occupancy of
such Property or otherwise. Except as described in Schedule 2.11(b), Seller has
no knowledge of any current uninsured physical damage to any Buyer Property in
excess of $25,000. To Seller's knowledge, except for repairs identified in the
Capital Expenditure Budget and Schedule (as defined below in Section 2.11(i)),
each Buyer Property: (x) is in good operating condition and repair and is
structurally sound and free of defects, with no material alterations or repairs
being required thereto under applicable law or insurance company requirements,
and (y) consists of sufficient land areas, driveways and other improvements and
lawful means of access and utility service and capacity to permit the use
thereof in the manner and for the purposes to which it is presently devoted (or,
in the case of the Development Properties (as defined below in Section 2.11(j)),
for the development and operation thereon of the applicable Project), except, in
each such case, to the extent that failure to meet such standards would not,
individually or in the aggregate with all other such failures, reasonably be
expected to have a Material Adverse Effect.

     (c) Seller has no knowledge (i) except as described in Schedule 2.11(c)that
any condemnation, eminent domain or rezoning proceedings are pending or
threatened with respect to any of the Buyer Properties, (ii) except as described
in Schedule 2.11(c), that any road widening or change of grade of any road
adjacent to any Buyer Property is underway or has been proposed, (iii) of any
proposed change in the assessed valuation of any Buyer Property other than
customarily scheduled revaluations, (iv) of any special assessment made or
threatened against any Property, or (v) that any of the Buyer Properties is
subject to any so-called "impact fee" or to any agreement with any Government
Authority to pay for sewer extension, oversizing utilities, lighting or like
expenses or charges for work or services by such Government Authority, except,
in the case of each of the foregoing, to the extent that same would not,
individually or in the aggregate with all other such items, reasonably be
expected to have a Material Adverse Effect.

     (d) To Seller's knowledge, each of the Buyer Properties is an independent
unit which does not rely on any facilities located on any property not included
in such Property to fulfill any municipal or governmental requirement or for the
furnishing to such Property of any essential building systems or utilities,
other than facilities the benefit of which inures to the Buyer Properties
pursuant to one or more valid easements. Each of the Buyer Properties is served
by public water and sanitary systems and all other utilities, and, to Seller's
knowledge, each of the Buyer Properties has lawful access to public roads, in
all cases sufficient for the current use and occupancy of that Property (or, in
the case of the Development Properties, for the development and operation
thereon of the applicable Project (as defined herein)). To Seller's knowledge,
all parcels of land included in each Buyer Property that purport to be
contiguous are contiguous and are not separated by strips or gores. To Seller's
knowledge, no portion of any Buyer

                                      B-19
   109

Property lies in any flood plain area (as defined by the U.S. Army Corps of
Engineers or otherwise) or includes any wetlands or vegetation or species
protected by any applicable laws. To Seller's knowledge, no improvements
constituting a part of any Buyer Property encroach on real property not
constituting a part of such Property.

     (e) Except for matters addressed in the Capital Expenditure Budget and
Schedule, no Property fails to comply with the requirements of the Americans
With Disabilities Act (the "ADA") except for such noncompliance as Seller
reasonably believes will not, individually or in the aggregate, have a Material
Adverse Effect.

     (f) Seller has provided to Parent and Buyer an accurate rent roll for each
Buyer Property as of September 30, 2000 (the "Rent Roll"), which identifies and
accurately describes each lease of space in each Buyer Property (collectively,
the "Leases"). Seller has delivered to Parent and Buyer an abstract of each
Lease (the "Abstracts") which accurately describes the material terms thereof.
With respect to each Lease for premises larger than 20,000 square feet of
rentable space (each a "Material Lease" and collectively, the "Material
Leases"), except as described in Schedule 2.11(f) and except for matters that
are not, individually or in the aggregate, reasonably expected to have a
material effect on any Buyer Property, (i) each of the Material Leases is valid
and subsisting and in full force and effect as against each party thereto, and
has not been amended, modified or supplemented, other than by any amendment,
modification or supplement that has been provided to Parent and Buyer, (ii) the
tenant under each of the Material Leases is in actual possession of the premises
leased thereunder, (iii) no tenant under any Material Lease is more than thirty
(30) days in arrears in the payment of rent, (iv) none of Seller or any of the
Subsidiaries has received any written notice from any tenant under any Material
Lease of its intention to vacate, (v) none of Seller or any of the Subsidiaries
has collected payment of rent under any Material Lease (other than security
deposits) for a period which is more than one (1) month in advance, (vi) no
notice of default has been sent or received by the landlord under any Material
Lease with respect to any defect that remains uncured as of the date hereof, no
default has occurred under any Material Lease and, to Seller's knowledge, no
event has occurred and is continuing which, with notice or lapse of time or
both, would constitute a default under any Material Lease, (vii) no tenant under
any of the Material Leases has any purchase option or kick-out right or is
entitled to any concession, allowance, abatement, set-off, rebate or refund,
(viii) none of the Material Leases and none of the rents or other amounts
payable thereunder has been assigned, pledged or encumbered except in connection
with financing secured by the applicable Buyer Property, which is described in
Schedule 2.9(c), (ix) no brokerage or leasing commission or other compensation
is due or payable to any Person with respect to or on account of any of the
Material Leases or any extensions or renewals thereof, (x) except as set forth
in the Abstracts, no space of a material size in any Buyer Property is occupied
by a tenant rent-free, (xi) no tenant under any of the Material Leases has
asserted any claim which is likely to affect the collection of rent from such
tenant, and (xii) the landlord under each Material Lease has fulfilled all of
its obligations thereunder in respect of tenant improvements and capital
expenditures. Other than the tenants identified in the Rent Roll and Abstracts
and parties to easement agreements which constitute Permitted Liens, no third
party has any right to occupy or use any portion of any Buyer Property. The Rent
Roll or Abstracts include a budget for all material tenant improvements and
similar material work required to be performed by the lessor under each of the
Material Leases.

     (g) Schedule 2.11(g) sets forth a complete and accurate list of all
material commitments, letters of intent or written understandings made or
entered into by Seller or any of the Subsidiaries as of the date hereof (i) to
lease any space larger than 20,000 rentable square feet at any of the Buyer
Properties, (ii) to sell, mortgage, or pledge any Buyer Property or to otherwise
enter into a material transaction or arrangement in respect of the ownership or
financing of any Buyer Property, or (iii) to purchase or acquire an option,
right of first refusal or similar right in respect of any real property, which,
in any such case has not yet been reduced to a written lease or contract, and
sets forth with respect to each such commitment, letter of intent or other
understanding the principal terms thereof.

     (h) Except as set forth in the Rent Roll or Abstracts, and except for
certain rights of first refusal which are set forth in the sections of the
partnership agreements referenced in Schedule 2.1(d) and which
                                      B-20
   110

relate to partnerships in which Seller, directly or indirectly, owns less than a
100% interest, none of Seller or any of the Subsidiaries has granted any
outstanding options or has entered into any outstanding contracts with others
for the sale, mortgage, pledge, hypothecation, assignment, sublease, lease or
other transfer of all or any part of any Buyer Property, and no person has any
right or option to acquire, or right of refusal with respect to, Seller's or any
Subsidiary's interest in any Buyer Property or any part thereof. Except as
described in Schedule 2.11(h), none of Seller or any Subsidiary has any
outstanding options or rights of first refusal or has entered into any
outstanding contracts with others for the purchase of any real property.

     (i) Schedule 2.11(i) contains a complete and accurate description of any
material noncompliance by any Property, to Seller's knowledge, with any law,
ordinance, code, health and safety regulation or insurance requirement (except
for the ADA, which is addressed in this respect in Section 2.11(e) above) other
than such noncompliance as would not, individually or in the aggregate,
reasonably be expected to have a Material Adverse Effect. Schedule 2.11(i) also
sets forth Seller's and each Subsidiary's capital expenditure budget and
schedule for each Buyer Property (the "Capital Expenditure Budget and
Schedule"), which describes the capital expenditures which Seller or any
Subsidiary has budgeted for such Property that was acquired prior to January 1,
2000 for the period from January 1, 2000 through December 31, 2000 and the
expected capital expenditures from February 1, 2001 through May 31, 2001. To
Seller's knowledge, the costs and time schedules for 2000 and 2001 (February
through May 2001) set forth in the Capital Expenditure Budget and Schedule are
reasonable estimates and projections. Except as described in Schedule 2.11(i),
there are no outstanding, or to Seller's knowledge, threatened requirements of
any insurance company which has issued an insurance policy covering any Buyer
Property, or of any board of fire underwriters or other body exercising similar
functions, requiring any repairs or alterations to be made to any Buyer
Property.

     (j) Schedule 2.11(j) contains a list of each Buyer Property which consists
of or includes undeveloped land or which is in the process of being developed or
rehabilitated (each, a "Development Property," and collectively, the
"Development Properties") and a brief description of the development or
rehabilitation intended by Seller or any Subsidiary to be carried out or
completed thereon (collectively, the "Projects"), including any budget and
development or rehabilitation schedule therefor prepared by or for Seller or any
Subsidiary (collectively, the "Development Budget and Schedule"). Except as
disclosed in Schedule 2.11(j), each Development Property is zoned for the lawful
development thereon of the applicable Project, and the Trust or a Subsidiary has
obtained all permits, licenses, consents and authorizations required for the
lawful development or rehabilitation thereon of such Project, except only for
such failure to meet the foregoing standards as would not, individually or in
the aggregate with all other such failures, reasonably be expected to have a
Material Adverse Effect. Except as described in Schedule 2.11(j), to Seller's
knowledge, there are no material impediments to or constraints on the
development or rehabilitation of any Project in all material respects within the
time frame and for the cost set forth in the Development Budget and Schedule
applicable thereto. In the case of each Project, the development of which has
commenced, to Seller's knowledge, the costs or expenses incurred in connection
with such Project and the progress thereof are, except as described in Schedule
2.11(j), consistent and in compliance in all material respects with all aspects
of the Development Budget and Schedule applicable thereto. All development and
rehabilitation efforts with respect to the Development Properties and the
Project have ceased.

     (k) Seller has disclosed to Buyer all adverse matters known to Seller with
respect to or in connection with the Buyer Properties (including the Leases and
the Tenancy Leases), which would, individually or in the aggregate, reasonably
be expected to have a Material Adverse Effect.

     (l) The ground leases underlying the leased Buyer Properties referenced in
Schedule 2.11(a) (collectively, the "Tenancy Leases") are listed in Schedule
2.11(l). Each of the Tenancy Leases is valid, binding and in full force and
effect against the applicable Subsidiary and, to Seller's knowledge, against the
other party thereto. Except as indicated in Schedule 2.11(l), none of the
Tenancy Leases is subject to any pledge, lien, sublease, assignment, license or
other agreement granting to any third party any interest in or any right to the
use or occupancy of any premises leased thereunder. To Seller's knowledge,
except
                                      B-21
   111

as described in Schedule 2.11(l), there is no pending or threatened proceeding
which is reasonably likely to interfere with the quiet enjoyment of the tenant
under any of the Tenancy Leases. Except as described in Schedule 2.11(l), no
payments under any Tenancy Lease are delinquent and no notice of default
thereunder has been sent or received by Seller or any of the Subsidiaries. There
does not exist under any of the Tenancy Leases any default, and, to Seller's
knowledge, no event has occurred which, with notice or lapse of time or both,
would constitute such a default, except as would not, individually or in the
aggregate with all other such defaults, be reasonably expected to have a
Material Adverse Effect.

     (m) Each of Seller and each of the Subsidiaries has good and sufficient
title to all the personal and other property and assets reflected in their books
and records as being owned by them (including those reflected in the balance
sheets of Seller and the Subsidiaries as of June 30, 2000, except as since sold
or otherwise disposed of in the ordinary course of business), free and clear of
all Liens, except for Permitted Liens which are not, individually or in the
aggregate, reasonably expected to have a material adverse effect on any
Property.

     2.12  Environmental Matters.

     (a) Except as disclosed on Schedule 2.12(a), to Seller's knowledge, each of
Seller and the Subsidiaries has obtained and now maintains as currently valid
and effective all permits required to be possessed by Seller or its Subsidiaries
under Environmental Laws (the "Environmental Permits") in connection with the
operation of its businesses and properties, all of which are listed in Schedule
2.12(a), except where the failure to have such Environmental Permit would not
individually or in the aggregate with all other failures to have a required
Environmental Permit, reasonably be expected to result in a Material Adverse
Effect. To Seller's knowledge, except as disclosed in the Environmental Reports
(as defined below), each of Seller and the Subsidiaries, and each Property, is
in compliance with all terms and conditions of the Environmental Permits and all
Environmental Laws, except for any noncompliance that would not, individually or

Seller or a Subsidiary. Seller has no knowledge of any actually and currently
existing circumstances that may prevent or interfere with such compliance in the
future.

     (b) Each of Seller and the Subsidiaries has made available to Parent and
Buyer all material written information and written communications (whether from
a Government Authority, citizens' group, employee or other person) in its
possession or control regarding (i) alleged or suspected noncompliance of any of
the Properties with any Environmental Laws or Environmental Permits or (ii)
alleged or suspected liability of Seller or any Subsidiary under any
Environmental Law.

     (c) There are no environmental liens or encumbrances on any of the
Properties and, to Seller's knowledge, no government actions have been taken or
are in process which are reasonably likely to subject any Property to such liens
or other encumbrances that would prevent the use of such Property as currently
conducted.

     (d) No Environmental Claim (as defined below) with respect to the
operations or the businesses of Seller or of any Subsidiary, or with respect to
the Properties, has been asserted or, to Seller's knowledge, threatened, and, to
Seller's knowledge, no circumstances exist with respect to Seller or any of the
Subsidiaries or the Properties that would reasonably be expected to result in
any Environmental Claim being asserted, in any such case, (i) against (x) Seller
or any of the Subsidiaries, or (y) any person whose liability for any
Environmental Claims Seller or any of the Subsidiaries has or may have retained
or assumed either contractually or by operation of law, and (ii) which would
reasonably be expected to have a Material Adverse Effect.

     (e) Except as disclosed in Schedule 2.12(e) or set forth in the
Environmental Reports: (i) none of Seller or any of the Subsidiaries has been
notified or has reason to believe that it will be notified of potential
responsibility in connection with any site that has been placed on, or proposed
to be placed on, the National Priorities List or its state or foreign equivalent
pursuant to the Comprehensive Environmental Response, Compensation and Liability

laws, (ii) to Seller's knowledge, no Materials of Environmental Concern are
present on, in or under

                                      B-22
   112

any Property in a manner or condition that is reasonably likely to give rise to
an Environmental Claim which would reasonably be expected to result in a
Material Adverse Effect, (iii) and to Seller's knowledge, none of Seller, any
Subsidiary or any tenant of any Property has Released or arranged for the
Release of any Materials of Environmental Concern at any location to an extent
or in a manner which would reasonably be expected to result in a Material
Adverse Effect on the Property, (iv) to Seller's knowledge, no underground
storage tanks, surface disposal areas, pits, ponds, lagoons, open trenches or
equipment is present at any Property, (iv) to Seller's knowledge, no
transformers, capacitors or other equipment containing fluid with more than 50
parts per million polychlorinated biphenyls are present at any Property, except
for any such transformers, capacitation or other equipment owned by any utility
company, and (vi) to Seller's knowledge, no employee, agent, contractor,
subcontractor or tenant of Seller or any of the Subsidiaries is now or has in
the past been exposed to friable asbestos or asbestos-containing material at any
Property.

     (f) Seller has made available to Buyer the most recent Phase I
environmental reports prepared for Seller or the Subsidiaries or otherwise in
the possession of any of them with respect to the environmental condition of any
Property (collectively, the "Environmental Reports").

     resulting from (x) the presence, generation, transportation, treatment,
     use, storage, disposal or Release of Materials of Environmental Concern or
     the threatened Release of Materials of Environmental Concern at any
     location, or (y) activities or conditions forming the basis of any

does not exist any accumulated deficiency within

                                      B-24

of the foregoing, neither Seller nor any ERISA Affiliate has engaged in any
transaction described in Section 4069 or Section 4204 of ERISA.

     (k) Except as set forth in Schedule 2.13(k), neither the execution and

Plans, Seller or any ERISA Affiliate is not obligated to continue any such Plan
beyond the Closing Date.

     (n) Each of the Pension Plans intended to be "qualified" within the meaning
of Code Section 401(a) is so qualified. Each Plan that is intended to qualify
for favorable tax treatment under Code Section 125 so qualifies and has been
operated in material compliance with Code Section 125.

     (o) There is sufficient liquidity of assets in each of the funded Plans to
promptly pay for the benefits earned and other liabilities owed under such Plan.
With respect to each of the Plans, no insurance contract, annuity contract, or
other agreement or arrangement with any financial or other organization would
impose any penalty, discount or other reduction on account of the withdrawal of
assets from such organization or the change in the investment of such assets.

     (p) All Form 5500s for each Plan required to be filed by Seller in the last
six (6) years have been filed.

     2.14  Labor Matters.  None of Seller nor any of the Subsidiaries is a party
to, or bound by, any collective bargaining agreement, contract or other
agreement or understanding with a labor union or labor union organization.
Except for the matters described in Schedule 2.14 (none of which matters would,
individually or in the aggregate with all other such matters, reasonably be
expected to have a Material Adverse Effect), there is no unfair labor practice
or labor arbitration proceeding pending or, to the knowledge of Seller,
threatened against Seller or any of the Subsidiaries. To the knowledge of
Seller, there are no organizational efforts with respect to the formation of a
collective bargaining unit presently being made or threatened involving
employees of Seller or of any of the Subsidiaries.

     2.15  No Payments to Employees, Officers or Directors.  Schedule 2.15
contains a true and complete list of all cash and noncash payments which will
become payable to each employee, officer or director of Seller or any Subsidiary
as a result of or in connection with the Merger, the Lend Lease Transaction or
the Manhattan Towers Transaction or those transactions taken as a whole. Except
as set forth in Schedule 2.15, there is no employment or severance contract or
other agreement requiring payments, cancellation of indebtedness or other
obligations to be made or satisfied on a change of control or otherwise as a
result of or in connection with the Merger, the Lend Lease Transaction or the
Manhattan Towers Transaction or those transactions taken as a whole, with
respect to any employee, officer or director of Seller or any Subsidiary.

     2.16  Insurance.  Seller maintains insurance policies covering the assets,
business, equipment, properties, operations, employees, officers, managers, and
directors of Seller and of each of the Subsidiaries
                                      B-25
   115

(collectively, the "Insurance Policies") which are of a type and in amounts
customarily carried by persons similar in size to Seller conducting businesses
similar to those of Seller. There is no material claim by Seller or by any of
the Subsidiaries pending under any of the Insurance Policies as to which
coverage has been questioned, denied or disputed by any underwriter of such
policy.

     2.17  Proxy Statement; Additional Filings.  The Proxy Statement and the
Additional Filings (both as defined in Section 5.1(a)) and all of the
information included or incorporated by reference therein (other than any
information supplied or to be supplied by Parent or Buyer for inclusion or
incorporation by reference therein) will not, as of the date such Proxy
Statement is first made available to the shareholders of Seller or as of the
date the Additional Filings are filed, and as of the time of the meeting of the
shareholders of Seller in connection with the transactions contemplated hereby,
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, in light of the circumstances under which they are made, not
misleading. The Proxy Statement and the Additional Filings will comply as to
form in all material respects with the provisions of the Exchange Act and the
rules and regulations promulgated by the SEC thereunder, except that no
representation is made by Seller with respect to the information supplied by
Parent or Buyer for inclusion or incorporation by reference therein.

     2.18  Takeover Statutes.  No "fair price," "moratorium," "control share
acquisition" or other antitakeover statute or similar statute or regulation
enacted by the State of Texas applies to the transactions contemplated by this
Agreement.

     2.19  Opinion of Financial Advisor.  Seller has received the opinion of
Chase Securities Inc. dated the date of this Agreement, a signed copy of which
will be provided to Parent and Buyer, to the effect that, on the date hereof,
the Common Consideration to be received by the holders of Trust Common Shares
pursuant to the Merger is fair to such holders from a financial point of view.

     2.20  Knowledge Defined.  As used herein, the phrase "to Seller's
knowledge" (or words of similar import) means the knowledge of those individuals
identified in Schedule 2.20, and includes any facts, matters or circumstances
set forth in any written notice from any Government Authority or any other
material notice received by any such individual with respect to Seller or any
Subsidiary, and also includes any matter of which Parent or Buyer informs Seller
in writing.

     2.21  Investment Company Act of 1940.  Neither Seller nor any of the
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").

Buyer, the valid and binding obligations of each of Parent and Buyer,
enforceable against Parent and Buyer in accordance with their respective terms
subject only to bankruptcy, insolvency, reorganization, moratorium or similar

Parent has authorized and approved and declared advisable this Agreement and the
transactions contemplated hereby in accordance with Ohio law.

execution and delivery by Parent or Buyer of this Agreement, nor the
consummation by Parent or Buyer of the transactions contemplated hereby and
thereby in accordance with the terms hereof and thereof, will:

     (a) conflict with or result in a breach of any provision of the either the
Parent's or Buyer's articles of incorporation, as amended, the Parent's code of
regulations or the Buyer's bylaws;

     (b) violate or conflict with any statute, regulation, judgment, order,

or result in the termination or in a right of termination or cancellation of, or
accelerate the performance required by, or result in the creation of any Lien
upon any of the properties of Parent or Buyer or of any of their subsidiaries
under, or result in being declared void, voidable or without further binding
effect, any of the terms, conditions or provisions of any note, bond, mortgage,
indenture, deed of trust or any franchise, permit, lease, contract, agreement or
other instrument, commitment or obligation to which Parent or Buyer or any of
their subsidiaries is a party, or by which Parent or Buyer or any of their
subsidiaries or any of their properties is bound or affected; or

     (d) require any consent, approval or authorization of, or declaration,
filing or registration with, any Government Authority, other than the Articles
of Merger pursuant to Section 1.3 hereof and the Filings, and any filings
required to be made with the Texas State Department of Assessments and Taxation,

or to be supplied by Parent or Buyer for inclusion or incorporation by reference
in the Proxy Statement or in the Additional Filings, as of the date the Proxy
Statement is mailed to the shareholders of Seller or as of the date the
Additional Filings are filed and as of the time of the meeting of the
shareholders of Seller in connection with the transactions contemplated hereby,
will 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, in light of the circumstances under which they are made, not
misleading.

     3.5  Investment Company Matters.  Neither Parent nor Buyer is, and after
giving effect to the consummation of Merger neither Parent nor Buyer will be, an
"investment company" or an entity "controlled" by an "investment company," as
such terms are defined in the Investment Company Act of 1940, as amended.

will be the sole shareholder of Buyer and own 10,000 shares of Buyer's common
stock. Other than as described in the immediately preceding sentence and except
for Parent's understandings with approximately 100 employees of Parent with
regard to the issuance to those employees of Surviving Company preferred stock
immediately following the Effective Time, at the Effective Time, there will be
no outstanding equity securities or other equity interests, debt securities or
derivative securities of Buyer or any oral or written agreements regarding the
issuance of same. There are no outstanding securities or assets convertible
into, exercisable for or exchangeable for any debt, equity or derivative
securities of Buyer or any oral or written agreements regarding the issuance of
same.

     3.7  Litigation; Compliance With Law.  Except as disclosed in Schedule 3.7,
there is no Action pending or, to Parent's or Buyer's knowledge, threatened
against either Parent or Buyer or any of their subsidiaries that would question
the validity of this Agreement or any action taken or to be taken in

                                      B-27
   117

connection herewith, or that would, individually or in the aggregate, reasonably
be expected to result in a Buyer or Parent Material Adverse Effect that would
affect their ability to perform their obligations under this Agreement.

     3.8  Funding.  Parent and Buyer have cash or financing commitments (as
described in Schedule 3.8) sufficient to enable them to perform their
obligations hereunder.

                                   ARTICLE 4

                                   COVENANTS

     4.1  Acquisition Proposals.  Prior to the Effective Time or the earlier
termination of this Agreement in accordance with its terms, Seller agrees that:

     (a) neither it nor any of the Subsidiaries shall initiate, solicit or
knowingly encourage, directly or indirectly, any inquiries or the making or
implementation of any proposal or offer (including, without limitation, any
proposal or offer to its shareholders) with respect to a merger, acquisition,
tender offer, exchange offer, consolidation, sale of assets or similar
transaction involving all or any significant portion of the assets or any equity
securities of Seller or any of the Subsidiaries, other than the transactions
contemplated by this Agreement, the Lend Lease Agreement and the Manhattan
Towers Agreement (any such proposal or offer being hereinafter referred to as an
"Acquisition Proposal") or engage in any negotiations concerning or provide any
confidential information or data to, or have any discussions with, any person
relating to an Acquisition Proposal, or otherwise facilitate any effort or
attempt to make or implement an Acquisition Proposal;

     (b) it shall direct and use its reasonable best efforts to cause its
officers, Board Managers, employees, agents and financial advisors not to engage
in any of the activities described in Section 4.1(a) except to the extent
expressly permitted by the proviso below;

     (c) it will immediately cease and cause to be terminated any existing
activities, discussions or negotiations with any parties conducted heretofore
with respect to any of the foregoing; and

     (d) it will notify Buyer promptly if Seller receives any such inquiries or
proposals, or any requests for such information, or if any such negotiations or
discussions are sought to be initiated or continued with it;

provided, however, that nothing contained in this Agreement shall prohibit the
Board of Managers (or the officers, Board Managers, employees, agents or
financial advisors of Seller acting at the direction of the Board of Managers)
from (i) furnishing information to or entering into discussions or negotiations
with, any person or entity that makes an unsolicited Acquisition Proposal, if,
and only to the extent that (x) the Board of Managers (excluding Parent's
designees) determines in good faith following consultation with counsel and with
Seller's financial advisors that such action is required for the Board of
Managers to comply with its duties to shareholders imposed by law or such
proposal is or could reasonably be expected to result in, a Superior Acquisition
Proposal (as hereinafter defined), (y) prior to furnishing such information to,
or entering into discussions or negotiations with, such person or entity, Seller
provides written notice to Parent and Buyer to the effect that it is furnishing
information to, or entering into discussions with, such person or entity, and
(z) subject to any confidentiality agreement with such person or entity, Seller
keeps Parent and Buyer informed of the status (not the terms) of any such
discussions or negotiations; or (ii) to the extent applicable, taking and
disclosing to Seller's shareholders a position contemplated by Rules 14d-9 and
14e-2 promulgated under the Exchange Act with regard to an Acquisition Proposal.
Nothing in this Section 4.1 shall (1) permit Seller to terminate this Agreement
(except as specifically provided in Article 7 hereof), (2) permit Seller to
enter into an agreement with respect to an Acquisition Proposal during the term
of this Agreement (other than a confidentiality agreement in customary form
executed as provided above) or (3) affect any other obligation of Seller under
this Agreement; provided, however, that the Board of Managers may approve and
recommend a Superior Acquisition Proposal and, in connection therewith, withdraw
or modify its approval or recommendation of this Agreement and the Merger. Any
disclosure that the Board of Managers may be
                                      B-28
   118

compelled to make with respect to the receipt of an Acquisition Proposal in
order to comply with its duties to shareholders of Seller or comply with
applicable law will not constitute a violation of this Section 4.1. As used
herein, "Superior Acquisition Proposal" means a bona fide Acquisition Proposal
made by a third party which the Board of Managers (excluding Parent's designees)
(or a duly constituted committee thereof charged with considering Acquisition
Proposals) determines in good faith following consultation with counsel and with
Seller's financial advisors to be more favorable to Seller's shareholders from a
financial point of view than the Merger and which the Board of Managers
(excluding Parent's designees) (or any such committee) determines is reasonably
capable of being financed and consummated.

     4.2  Conduct of Seller's Business Pending Merger.  Prior to the Effective
Time, except as consented to in writing by Parent and Buyer (which consent or
withholding of consent shall be communicated by Parent and Buyer to Seller
within seven (7) business days of the date of the request for such consent;
provided, however, if Parent and Buyer do not respond to the request for consent
within such seven (7) day period, they shall be deemed to have consented to such
request), as expressly provided for in this Agreement, the Lend Lease Agreement
or the Manhattan Towers Agreement, Seller shall, and shall cause each of the
Subsidiaries to:

     (a) conduct its business only in the usual, regular and ordinary course and
in substantially the same manner as heretofore and take all action necessary to
continue to qualify as a REIT;

     (b) use its commercially reasonable efforts to preserve intact its business
organization and goodwill and keep available the services of its officers and
key employees;

     (c) confer on a regular basis with one or more representatives of Parent
and Buyer to report operational matters of materiality and, subject to Section
4.1, any proposal to engage in material transactions;

     (d) promptly notify Parent and Buyer of any material emergency or other
material change in the condition (financial or otherwise), business, properties,
assets, liabilities or the normal course of its businesses or in the operation
of its properties, or of any material governmental complaints, investigations or
hearings (or communications indicating that the same may be contemplated);

     (e) promptly deliver to Parent and Buyer true and correct copies of any
report, statement or schedule filed with the SEC subsequent to the date of this
Agreement and prior to the Closing;

     (g) duly and timely file all material reports, tax returns and other
documents required to be filed with federal, state, local and other authorities,

extensions do not adversely affect Seller's status as a qualified REIT under the
Code;

     (h) not make or rescind any material express or deemed election relative to
Taxes that would adversely affect Seller's status as a REIT or the status of any
Subsidiary as a partnership for federal income tax purposes or as a qualified
REIT subsidiary under Section 856(i) of the Code, as the case may be;

     (i) make reasonably budgeted capital expenditures in the ordinary course of
business, but not acquire, enter into any option to acquire, or exercise an
option or contract to acquire, additional real property, incur additional
indebtedness except for working capital under its revolving lines of credit,
encumber assets or commence construction of, or enter into any agreement or
commitment to develop or construct, other real estate projects, except for
activities necessary to proceed with the construction of the projects which have
been budgeted and are disclosed in Schedule 2.11(i), in accordance with the
agreements in existence on the date of this Agreement and previously furnished
to Parent and Buyer (the "Development Agreements");

certificate of incorporation, bylaws, code of regulations, partnership
agreement, operating agreement or joint venture agreement or comparable charter
or organization document of any Subsidiary;

     (l) grant no option or other right or commitment relating to its or any
Subsidiary's shares of beneficial interest (including annual grants to Board
Managers), membership interests or units of limited partnership interest or any

membership interests or units of limited partnership interest, or any security
the value of which is measured by its or any Subsidiary's shares of beneficial
interest, or any security subordinated to the claim of its or any Subsidiary's
general creditors, and not amend or waive any rights under any outstanding
Options;

     (m) except as provided in Section 5.8 and in connection with the use of
Trust Common Shares to pay the exercise price or tax withholding in connection
with equity-based employee benefit plans by the participants therein, not (i)
authorize, declare, set aside or pay any dividend or make any other distribution
or payment with respect to any Trust Common Shares except as may be required to
preserve the status of Seller as a REIT under the Code or to prevent Seller from
having to pay federal income tax, or (ii) directly or indirectly redeem,
purchase or otherwise acquire any shares of capital stock, membership interests
or units of partnership interest in Seller or any Subsidiary or any option,
warrant or right to acquire, or security convertible into, shares of beneficial
interest, membership interests, or units of partnership interest in Seller or
any Subsidiary, except for redemptions of Trust Common Shares required under
Article V of Seller's Trust Declaration in order to preserve the status of
Seller as a REIT under the Code;

     (n) not sell, lease, mortgage, subject to Lien or otherwise dispose of any

(absolute, accrued, asserted or unasserted, contingent or otherwise) which are
material to Seller and the Subsidiaries taken as a whole, other than the
payment, discharge or satisfaction, in the ordinary course of business
consistent with past practice or in accordance with their terms, of liabilities

                              ADDITIONAL COVENANTS

     5.1  Preparation of the Proxy Statement; Seller Shareholders Meeting.

     (a) The parties shall cooperate and promptly prepare, and Seller shall file
with the SEC as soon as practicable a proxy statement with respect to the
meeting of the shareholders of Seller in connection with the Merger and the Lend
Lease Transaction (the "Proxy Statement"). The parties shall cooperate and
promptly prepare and the appropriate party shall file with the SEC as soon as
practicable any other filings required under the Exchange Act ("Additional
Filings"), including without limitation, a Rule 13e-3 Transaction Statement on
Schedule 13E-3 with respect to the Merger to be filed jointly by Seller, Parent
and Buyer, together with any required amendments thereto. Each of Seller, Parent
and Buyer agrees that the information provided by it for inclusion in the Proxy
Statement, the Additional Filings, and each amendment or supplement thereto, at
the time of mailing or filing thereof and at the time of the meeting of
shareholders of Seller, will not include 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 under which they were
made, not misleading. Seller will use its reasonable best efforts, and Parent
and Buyer will cooperate with Seller, to (i) file a preliminary Proxy Statement
with the SEC and (ii) cause the Proxy Statement to be mailed to Seller's
shareholders, in each case, as promptly as practicable (including clearing the
Proxy Statement with the SEC). The parties will notify one another promptly of
the receipt of any comments from the SEC and of any request by the SEC for
amendments or supplements to the Proxy Statement or the Additional Filings or
for additional information and will supply one another with copies of all
correspondence between such party or any of its representatives and the SEC with
respect to the Proxy Statement or the Additional Filings. The parties shall
cooperate to cause the Proxy Statement and any Additional Filings to 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 Proxy Statement or the Additional Filings, Seller on the one hand, and
Parent and Buyer on the other hand, shall promptly inform the other of such
occurrence and cooperate in filing with the SEC and mailing to the shareholders
of Seller, as applicable, such amendment or supplement to the Proxy Statement or
Additional Filing. Seller shall use its reasonable best efforts to cause the
other parties to the Lend Lease Agreement and the Manhattan Towers Agreement to
take such actions and provide such cooperation as may be necessary to ensure
that the Proxy Statement, the Additional Filings, and each amendment or
supplement thereto, at the time of mailing or filing thereof and at the time of
the meeting of shareholders of Seller, will not include 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 under
which they were made, not misleading, and to facilitate Seller's compliance with
its obligations under this Section 5.1.

     (b) To the extent the Proxy Statement contains financial statements of
Seller, it is a condition to the mailing of the Proxy Statement and the making
of the Additional Filings that if they so request, Parent and Buyer shall have
received a "comfort" letter or an "agreed upon procedures" letter from Ernst &
Young LLP, independent public accountants for Seller, of the kind contemplated
by the Statement of Auditing Standards with respect to Letters to Underwriters
promulgated by the American Institute of Certified Public Accountants (the
"AICPA Statement"), dated as of the date on which the Proxy Statement is to be
mailed to the shareholders of Seller, addressed to Parent and Buyer, in form and
substance reasonably satisfactory to Parent and Buyer, concerning the procedures
undertaken by Ernst & Young LLP with respect to the financial statements and
information of Seller and the Subsidiaries contained in the Proxy Statement and
the Additional Filings and the other matters contemplated by the AICPA Statement
and otherwise customary in scope and substance for letters delivered by

     (c) Seller will, as soon as practicable following the date of this
Agreement, duly call, give notice of, convene and hold a meeting of its
shareholders, such meeting to be held no sooner than twenty (20) business days
nor later than forty-five (45) days following the date the Proxy Statement is
mailed to

                                      B-32
   122

the shareholders of Seller (the "Seller Shareholders Meeting") for the purpose
of obtaining Seller's shareholders' approval of the Merger and the Lend Lease
Transaction. Seller shall be required to hold the Seller Shareholders Meeting,
regardless of whether the Board of Managers has withdrawn, amended or modified
its recommendation that its shareholders adopt this Agreement and approve the
Merger and the Lend Lease Transaction, unless this Agreement has been terminated
pursuant to Section 7.1. Seller will, through the Board of Managers, recommend
that its shareholders adopt this Agreement and approve the transactions
contemplated hereby, including the Merger, and approve the Lend Lease
Transaction and the Manhattan Towers Transaction; however, prior to the Seller
Shareholders Meeting, such recommendation may be withdrawn, modified or amended
if Seller shall have received a Superior Acquisition Proposal, but only to the
extent expressly permitted under Section 4.1.

     (d) If, on the date for the Seller Shareholders Meeting established
pursuant to Section 5.1(c) of this Agreement, Seller has not received duly
executed proxies which, when added to the number of votes represented in person
at the meeting by persons who intend to vote to adopt this Agreement and approve
the Lend Lease Transaction, will constitute a sufficient number of votes to
adopt this Agreement and approve those transactions (but less than a majority of
the outstanding Trust Common Shares have indicated their intention to vote
against, or have submitted duly executed proxies voting against, the adoption of
this Agreement and approval of those transactions), then Seller shall recommend
the adjournment of its shareholders meeting until the date ten (10) days after
the originally scheduled date of the shareholders meeting.

     5.2  Access to Information: Confidentiality.  Prior to the Effective Time,
subject to the requirements of confidentiality agreements with third parties,

Buyer and to their officers, employees, accountants, counsel, financial advisors
and other representatives, upon reasonable advance notice, reasonable access
during normal business hours to all of Seller's properties, books, contracts,
commitments, personnel and records and, during such period, Seller shall, and
shall cause each of the Subsidiaries to, furnish promptly to Parent and Buyer
all other information concerning its business, properties and personnel as
Parent and Buyer may reasonably request. Parent and Buyer will hold, and will
use commercially reasonable efforts to cause their officers, employees and
representatives to hold, any non-public information in confidence.

     5.3  Reasonable Efforts; Notification.

     (a) Subject to the terms and conditions herein provided, Seller, on the one

efforts to cooperate with one another in (A) determining which filings are
required to be made prior to the Effective Time with, and which consents,
approvals, permits or authorizations are required to be obtained prior to the
Effective Time from, governmental or regulatory authorities of the United

connection with the execution and delivery of this Agreement, and the

such filings and timely seeking all such consents, approvals, permits and
authorizations; (ii) use all reasonable best efforts (other than the payment of

Seller and Parent and Buyer; and (iii) use all reasonable best efforts to take,
or cause to be taken, all other action and do, or cause to be done, all other
things necessary, proper or appropriate to consummate and make effective the
transactions contemplated by this Agreement. If at any time after the Effective
Time any further action is necessary or desirable to carry out the purpose of
this Agreement, the Surviving Company shall take all such necessary action.

     (b) Seller shall give prompt notice to Parent and Buyer, and Parent and
Buyer shall give prompt notice to Seller, (i) if 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) of the failure by it 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, but no such notification shall affect the

                                      B-33
   123

representations, warranties, covenants or agreements of the parties or the
conditions to the obligations of the parties under this Agreement.

     5.4  Public Announcements.  Parent, Buyer and Seller will consult with each
other before issuing, and provide each other the opportunity to review and
comment upon, any press release or other written public statements with respect
to the transactions contemplated by this Agreement, and shall not issue any such
press release or make any such written 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 transactions contemplated by this Agreement will be in the form
agreed to by the parties hereto prior to the execution of this Agreement.

     5.5  Transfer and Gains Taxes.  Parent, Buyer and Seller shall cooperate in

(together with any related interests, penalties or additions to tax, "Transfer

     5.6  Benefit Plans and Other Employee Arrangements.

     (a) None of Parent, Buyer or the Surviving Company has any obligation to
continue the employment of any employee of Seller after the Effective Time,
other than any such obligation arising under any agreement other than this
Agreement or imposed by law.

     (b) After the Effective Time, all employees of Seller who are not employed
by the Surviving Company shall be eligible to receive health care continuation
coverage, as provided pursuant to the continuation coverage under Section 601,
et seq., of ERISA, under the group health plan maintained by Seller immediately
prior to Closing; provided, however, that if such plan is terminated, the
Surviving Company or the Parent shall provide healthcare continuation benefits
under the terms of a group health plan maintained for employees of the Surviving
Company or the Parent, as applicable, but only to the extent required by Section
601 et seq., of ERISA, under the group health plan maintained by Seller prior to
Closing (the "Former Employees"). After the Effective Time, the Surviving
Company or Parent shall fulfill Seller's responsibilities to provide
continuation coverage for the Former Employees but only to the extent required
under Section 601, et seq., of ERISA.

     5.7  Indemnification From and After the Effective Time.

     (a) From and after the Effective Time, the Surviving Company shall provide
exculpation and indemnification for 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, employee, Board Manager or director of Seller or any Subsidiary (the
"Indemnified Parties") which is the same as the exculpation and indemnification
provided to the Indemnified Parties by Seller and the Subsidiaries (including
advancement of expenses) immediately prior to the Effective Time in the Trust
Declaration and Bylaws, in any separate indemnification agreements (each as
listed on Schedule 5.7(a) hereto) between Seller and its officers and Board
Managers, or in any Employee Benefit Plan or Pension Plan, in each case as in
effect on the date hereof or pursuant to the REIT Act; provided, that such
exculpation and indemnification covers only actions or omissions on or prior to
the Effective Time, including, without limitation, all transactions contemplated
by this Agreement.

     (b) In addition to the rights provided in Section 5.7(a) above, in the
event of any threatened or actual claim, action, suit, proceeding or
investigation, whether civil, criminal or administrative, including, without
limitation, any action by or on behalf of any or all security holders of Seller,
Surviving Company, Parent or Buyer, or any Subsidiary or Buyer Subsidiary, or by
or in the right of Seller, Surviving Company, Parent or Buyer, or any Subsidiary
or Buyer Subsidiary, or any claim, action, suit, proceeding or investigation in
which any 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, Board Manager, employee
or director of Seller or any
                                      B-34
   124

Subsidiary (the "Indemnified Parties") is, or is threatened to be, made a party
based in whole or in part on, or arising in whole or in part out of, or
pertaining to (i) the fact that he is or was an officer, employee, Board Manager
or director of Seller, Surviving Company, or any of the Subsidiaries or any
action or omission or alleged action or omission by such person in his capacity
as an officer, employee, Board Manager or director of Seller, Surviving Company,
or of any of the Subsidiaries, or (ii) this Agreement, the Lend Lease Agreement
and the Manhattan Towers Agreement or the transactions contemplated hereby and
thereby, whether in any case asserted or arising before or after the Effective
Time, Parent, Buyer, Seller, Surviving Company and the Indemnified Parties
hereby agree to cooperate in all reasonable respects in the defense of such
claim, action, suit, proceeding or investigation. It is understood and agreed
that, from and after the Effective Time, the Surviving Company shall indemnify
and hold harmless, as and to the full extent permitted by applicable law, each
Indemnified Party against any losses, claims, liabilities, expenses (including
reasonable attorneys' fees and expenses), judgments, fines and amounts paid in
settlement in accordance herewith in connection with any such threatened or
actual claim, action, suit, proceeding or investigation. In addition, after the
Effective Time, in the event of any such threatened or actual claim, action,
suit, proceeding or investigation, the Surviving Company shall promptly pay in
advance reasonable expenses and costs incurred by each Indemnified Person as
they become due and payable in advance of the final disposition of the claim,
action, suit, proceeding or investigation to the fullest extent and in the
manner permitted by law. No Indemnified Party will be required to consent to
entry of any judgment or enter into any settlement which does not include as an
unconditional term thereof the giving by the claimant or plaintiff to such
Indemnified Party of a release from all liability in respect to such claim or
litigation. Notwithstanding the foregoing, the Surviving Company shall not be
obligated to advance any expenses or costs prior to receipt of an undertaking by
or on behalf of the Indemnified Party, such undertaking to be accepted without
regard to the creditworthiness of the Indemnified Party, to repay any expenses
advanced if it shall ultimately be determined that the Indemnified Party is not
entitled to be indemnified against such expense. Notwithstanding anything to the
contrary set forth in this Agreement, the Surviving Company (x) shall not be
liable for any settlement effected without its prior written consent, and (y)
shall not have any obligation hereunder to any Indemnified Party to the extent
that a court of competent jurisdiction shall determine in a final and
nonappealable order that such indemnification is prohibited by applicable law.
In the event of a final and nonappealable determination by a court that any
payment of expenses is prohibited by applicable law, the Indemnified Party shall
promptly refund to the Surviving Company the amount of all such expenses
theretofore advanced pursuant hereto.

     (c) Any Indemnified Party hereunder will (i) give prompt notice to the
Surviving Company of any claim which arises from or after the Effective Time
with respect to which it seeks indemnification and (ii) permit the Surviving
Company to assume the defense of such claim with counsel reasonably satisfactory
to a majority of the Indemnified Parties; provided, however, if the Indemnified
Parties include the Parent's designees who serve or served as Board Managers,
such Parent designees shall have no vote in the selection of or approval of
counsel for all of the Indemnified Parties. In connection with the selection of
counsel to represent the Indemnified Parties in connection with clause (ii)
above, the Surviving Corporation shall propose counsel to represent the
Indemnified Parties. The applicable Indemnified Parties shall have the right to
approve such counsel, but such approval shall not be unreasonably withheld. If
the proposed counsel is not approved, the Surviving Company shall continue to
propose counsel until counsel for the Surviving Company is approved by the
applicable Indemnified Parties. Any Indemnified Party shall have the right to
employ separate counsel and to participate in the defense of such claim, but the
fees and expenses of such counsel shall be at the expense of such person unless:
(x) the Surviving Company has agreed, in writing, to pay such fees or expenses;
(y) the Indemnifying Party shall have failed to assume the defense of such claim
after the receipt of notice from the Indemnified Party as required above and
failed to employ counsel reasonably satisfactory to a majority of the
Indemnified Parties (other than the DDR designees that are or were Board
Managers) or (z) based upon advice of counsel to such Indemnified Party and
concurrence therewith by counsel for the group of Indemnified Parties in such
matter, there shall be one or more defenses available to such Indemnified Party
that are not available to the Surviving Company or there shall exist conflicts
of interest between such Indemnified Party and the

                                      B-35
   125

Surviving Company and/or the other Indemnified Parties (in which case, if the
Indemnified Party notifies the Surviving Company in writing that such
Indemnified Party elects to employ separate counsel at the expense of the
Surviving Company, the Surviving Company shall not have the right to assume the
defense of such claim on behalf of such Indemnified Party), in each of which
events the reasonable fees and expenses of such counsel (which counsel shall be
reasonably acceptable to the Surviving Company) shall be at the expense of the
Surviving Company.

     (d) At or prior to the Effective Time, Seller shall purchase on or before
the Effective Time and thereafter the Surviving Company shall maintain in effect
until the sixth anniversary of the Effective Time, "run-off" directors' and
officers' liability insurance policy coverage for Seller's Board Managers and
officers which will provide the Board Managers and officers with coverage on
substantially similar terms as currently provided by Seller to such Board
Managers and officers. Seller and Buyer shall have the right to review and
approve any such policy, which approval shall not be unreasonably withheld.

     (e) This Section 5.7 is intended for the irrevocable benefit of, and to
grant third party rights to, the Indemnified Parties and their successors,
assigns and heirs and shall be binding on the Indemnified Parties, Buyer, Seller
and all successors and assigns of Buyer and Seller. Each of the Indemnified
Parties shall be entitled to enforce the covenants contained in this Section 5.7
and Buyer and Seller acknowledge and agree that each Indemnified Party would
suffer irreparable harm and that no adequate remedy at law exists for a breach
of such covenants and such Indemnified Party shall be entitled to injunctive
relief and specific performance in the event of any breach of any provision in
this Section 5.7.

     (f) In the event that the Surviving Company or any of its respective
successors or assigns consolidates with or merges into any other person and
shall not be the continuing or surviving corporation or entity of such
consolidation or merger, then, and in each such case, the successors and assigns
of such entity shall assume the obligations set forth in this Section 5.7, which
obligations are expressly intended to be for the irrevocable benefit of, and
shall be enforceable by, each Board Manager, director and officer and their
respective successors, assigns and heirs covered hereby.

     (g) Seller represents and warrants that it has not created an
indemnification trust of the kind referred to in the indemnification agreements
listed on Schedule 5.7(a) and agrees that it will not create such a trust at or
prior to the Effective Time.

     (h) The rights granted to the Indemnified Parties in this Section 5.7 are
in addition to any other rights to which the Indemnified Parties may be
entitled.

     5.8  Declaration of Dividends and Distributions.  From and after the date
of this Agreement, Seller shall not pay any dividend or make any distribution to
its shareholders without the prior written consent of Parent and Buyer, but the
written consent of Parent and Buyer shall not be required for the authorization
and payment of the Final Dividend (if any). The foregoing restrictions shall not
apply, however, to the extent a distribution by Seller is necessary for Seller
to maintain REIT status or to prevent Seller from having to pay federal income
tax; but, except with respect to the Final Dividend, in the event of such a
distribution, the aggregate cash consideration payable to holders of Trust
Common Shares in the Merger shall be reduced by the aggregate amount of such
distribution, and the Common Consideration per share shall be reduced
accordingly.

     5.9  Outside Property Management Agreements.  Seller will not, and will not
permit any of the Subsidiaries to, amend any property management agreement with
any party that is not an Affiliate of the Seller or the Subsidiaries (each, an
"Outside Property Management Agreement"). Seller will not, and will not permit
any of the Subsidiaries to, renew any Outside Property Management Agreement
except on terms which are the same as the existing Outside Property Management
Agreement or more favorable to Seller or the applicable Subsidiary than the
existing Outside Property Management Agreement.

     5.10  Lend Lease and Manhattan Towers Transactions.  Seller shall comply
with all of its obligations under the Lend Lease Agreement and under the
Manhattan Towers Agreement and shall use all reasonable best efforts to take, or
cause to be taken, all other action and do, or cause to be done, all

                                      B-36
   126

other things necessary, proper or appropriate to consummate and make effective
the Lend Lease Transaction and the Manhattan Towers Transaction.

     5.11  Parent Guarantee.  Parent hereby guarantees the performance of
Buyer's and the Surviving Company's obligations under this Agreement, including,
without limitation, any such obligation arising under Section 5.7 of this
Agreement.

     5.12  Share Purchase Agreement.  If the Merger is not consummated by May
31, 2001 as a result of a breach by Parent or Buyer of any of its obligations
hereunder, Parent's and Seller's rights and obligations under Section 6.6 of the
Share Purchase Agreement dated July 30, 1998 between Parent and Seller, as
amended by Amendment No. One to Share Purchase Agreement dated as of September
14, 1998 between Parent and Seller, will be extended from November 20, 2000 by
the number of days between June 19, 2000 and the later of (i) the date on which
that breach occurs or (ii) the first date on which any Board Manager that is not
a designee of Parent becomes aware of the breach.

     5.13  Lend Lease and Manhattan Towers Agreements.  Seller shall not amend
the Lend Lease Agreement or the Manhattan Towers Agreement in any manner
whatsoever that affects the economic consequences or imposes any additional
obligations on AIP or any AIP Affiliates thereunder without Parent's prior
written consent. Seller shall provide Parent with immediate written notice of
any modification or amendment, including a copy thereof, to the Lend Lease
Agreement or the Manhattan Towers Agreement.

     5.14  Voting Agreement by Parent.  Parent hereby agrees that it shall vote
all Trust Common Shares owned, directly or indirectly, of record or
beneficially, by it and shall cause each of its Affiliates (excluding
individuals, but including, but not limited, to Buyer to vote all Trust Common
Shares owned, directly or indirectly, of record or beneficially, by them in
favor of the Merger and in favor of the transactions contemplated by the Lend
Lease Agreement. The parties agree that any breach of this Section 5.14 by
Parent would result in irreparable damage to Seller inadequately compensable in
damages; therefore, this Section 5.14 shall be specifically enforceable, and any
breach or threatened breach of this Section 5.14 will be the proper subject of a
temporary or permanent injunction or restraining order. Further, each party
hereto and its successors, heirs, representatives and assigns waive any claim or
defense that there is an adequate remedy at law for breach or threatened breach.

     5.15  Settlement of Litigation.  On or prior to the Effective Date, (i) if
a party seeks indemnity from Seller, Seller shall give prompt notice thereof to
Parent; and (ii) Seller shall not settle any litigation relating to the Merger,
the Lend Lease Transaction or the Manhattan Towers Transaction or any other
litigation initiated by or on behalf of any shareholder of Seller in his/her or
its capacity as a shareholder, without the prior written consent of Parent,
which shall not be unreasonably withheld or delayed.

     Notwithstanding the foregoing, Seller shall be deemed to have satisfied the
conditions of Section 6.2(j), (k), (l) and (m) if, based on calculations made no
more than ten (10) days before the

                                      B-39
   129

scheduled Proxy Statement mailing, with respect to a date two (2) business days
after the scheduled date set forth in the Proxy Statement for the Seller
Shareholders Meeting (the "Anticipated Closing Date"), the difference between
(A) the sum of the actual amounts of the items described in Section 6.2(j), (k)
and (m) minus the actual amount of Section 6.2(l) (the result of such
calculation being referred to herein as the "Base Amount") and (B) $173,564,000,
is $1,000,000 or less.

     The parties agree that Seller shall calculate the Base Amount in accordance
with this Section 6.2(m) as of the Anticipated Closing Date and deliver such
calculation (including supporting documentation) to Parent and Buyer no more
than seven (7) days before the scheduled Proxy Statement mailing date. Seller
agrees to provide Buyer and Parent with any additional supporting documentation
for the calculation of the Base Amount that is reasonably requested by Buyer and
Parent, within forty-eight (48) hours after the request therefor. Within four
(4) business days after the receipt of Seller's calculation (assuming Seller has
promptly provided all supporting documentation requested), Parent and Buyer
shall provide Seller with a written notice of their agreement or dispute with
Seller's calculation. Assuming Parent and Buyer have timely provided Seller with
notice of their dispute, Seller agrees not to mail the Proxy Statement unless
and until Parent and Buyer have agreed in writing with Seller's calculation of
the Base Amount or the Base Amount is otherwise determined pursuant to this
Section 6.2. The parties agree to negotiate in good faith to attempt to settle
any disagreement or dispute in the calculation of the Base Amount. If, however,
Seller, Parent and Buyer are unable to settle any disagreement or dispute within
five (5) days after Parent and Buyer notify Seller in writing of a disagreement
or dispute, the disagreement or dispute shall be submitted (along with any
supporting documentation a party wishes to provide) within two (2) business days
after the end of that five (5) day period to Deloitte & Touche LLP for
resolution within ten (10) business days after submission thereof to that firm,
and the decision of Deloitte & Touche LLP shall be final and binding on the
parties. All costs incurred in connection with the resolution of any dispute by
Deloitte & Touche LLP, including expenses and fees for services rendered, shall
be borne equally by Buyer and Seller. If the Base Amount is more than $1,000,000
above $173,564,000, the Common Consideration shall be increased in an amount
equal to the amount by which the Base Amount calculated in this Section 6.2(m)
exceeds $173,564,000, divided by the number of Trust Common Shares outstanding
immediately prior to the Effective Time (including, without limitation, the
Trust Common Shares held, directly or indirectly, by Parent).

     (n) Debt.  On the Anticipated Closing Date, the aggregate principal amount
of the indebtedness for money borrowed by Seller and its Subsidiaries and
available to them under lines of credit shall not exceed $137,400,000.

     (o) Voting Agreements.  Each of ABKB/LaSalle Securities Limited
Partnership, LaSalle Advisors Limited Partnership, Morgan Stanley Asset
Management, Inc. and USAA Real Estate Company shall have voted for the Merger at
the Seller Shareholders Meeting in accordance with the Voting Agreements
executed by it at or prior to the execution of this Agreement.

     Notwithstanding anything to the contrary in this Agreement, Parent and
Buyer may not terminate this Agreement because of the commencement after the
date hereof of litigation that challenges the validity of this Agreement, the
Lend Lease Agreement or the Manhattan Towers Agreement or of any action taken or
to be taken in connection herewith or therewith, unless any such litigation has
resulted in the granting of injunctive relief that prevents the consummation of
the Merger, the Lend Lease Transaction or the Manhattan Towers Transaction or
any of the other transactions contemplated hereby or thereby, and such
injunctive relief has not been dissolved or vacated.

     6.3  Conditions to Obligations of Seller.  The obligation of Seller to
effect the Merger and to consummate the other transactions contemplated to occur
on the Closing Date is further subject to the following conditions, any one or
more of which may be waived by Seller:

     (a) Representations and Warranties.  The representations and warranties of
Parent and Buyer set forth in this Agreement shall be true and correct in all
material respects (except for representations having a materiality or Buyer
Material Adverse Effect qualification, which shall be correct in all respects)
as of the date of this Agreement and as of the Closing Date, as though made on
and as of the Closing Date,
                                      B-40
   130

except to the extent the representation or warranty is expressly limited by its
terms to another date, and Seller shall have received a certificate (which
certificate may be qualified by Knowledge to the same extent as the
representations and warranties of Parent and Buyer contained herein are so
qualified) signed on behalf of Parent by the chief executive officer and the
chief financial officer of Parent, in such capacities, to such effect.

     (b) Performance of Obligations of Parent and Buyer.  Parent and Buyer shall
have performed in all material respects each obligation required to be performed
by them under this Agreement at or prior to the Effective Time, and Seller shall
have received a certificate of each of Parent and Buyer signed on behalf of
Parent or Buyer, as applicable, by the chief executive officer or the chief
financial officer of Parent or Buyer, as applicable, in such capacity, to such
effect.

     (c) Material Adverse Effect.  Since the date of this Agreement, there shall
have been no Buyer or Parent Material Adverse Effect and Seller shall have
received a certificate of the chief executive officer and chief financial
officer of each of Buyer and Parent, in such capacities, certifying to such
effect.

     (d) Consents.  All consents and waivers (including, without limitation,
waivers of rights of first refusal) from third parties necessary in connection
with the consummation of the transactions contemplated hereby shall have been
obtained, other than such consents and waivers from third parties, which, if not
obtained, would not result, individually or in the aggregate, in a Buyer
Material Adverse Effect or a Seller Material Adverse Effect, and Seller shall
have obtained the Estoppel Certificates.

     (e) Common Consideration.  The Common Consideration is $13.74 or more.

     Notwithstanding anything to the contrary in this Agreement, Seller may not
terminate this Agreement because of the commencement after the date hereof of
litigation that challenges the validity of this Agreement, the Lend Lease
Agreement or the Manhattan Towers Agreement or of any action taken or to be
taken in connection herewith, unless any such litigation has resulted in the
granting of injunctive relief that prevents the consummation of the Merger or
any of the other transactions contemplated hereby and such injunctive relief has
not been dissolved or vacated.

                                   ARTICLE 7

                       TERMINATION, AMENDMENT AND WAIVER

     7.1  Termination.  This Agreement may be terminated at any time prior to
the filing of the Articles of Merger with the County Clerk of Dallas County,
Texas, and the Secretary of State of the State of Texas, whether before or after
the approval of Seller's shareholders is obtained:

     (a) by mutual written consent duly authorized by the Board of Directors of
Parent and of Buyer and the Board of Managers;

     (b) by Parent or Buyer, upon a breach of any representation, warranty,
covenant, obligation or agreement on the part of Seller set forth in this
Agreement, in any case such that the conditions set forth in Section 6.2(a) or
Section 6.2(b), as the case may be, would be incapable of being satisfied by May
31, 2001 (subject to extension in accordance with this Agreement), or upon a
failure of the Lend Lease Transaction or the Manhattan Towers Transaction to
close in accordance with the Lend Lease Agreement or the Manhattan Towers
Agreement, as applicable, because of a breach by Seller of its obligations
thereunder;

     (c) by Seller, upon a breach of any representation, warranty, covenant,
obligation or agreement on the part of Parent or Buyer set forth in this
Agreement, in any case such that the conditions set forth in Section 6.3(a) or
Section 6.3(b), as the case may be, would be incapable of being satisfied by May
31, 2001 (subject to extension in accordance with this Agreement);

     (d) by either Buyer or Seller, if any judgment, injunction, order, decree
or action by any Governmental Entity of competent authority preventing the
consummation of the Merger is issued on or

                                      B-41
   131

before May 31, 2001 and remains in effect on May 31, 2001 (subject to extension
in accordance with this Agreement);

     (e) by Parent, Buyer or Seller, if the Merger shall not have been
consummated on or before May 31, 2001; but a party may not terminate this
Agreement pursuant to this clause (e) if it shall have breached in any material
respect its obligations under this Agreement in any manner that shall have
proximately contributed to the occurrence of the failure referred to in this
clause;

     (f) by either Seller (unless Seller is in breach of its obligations under
Section 5.1) or Parent or Buyer if, upon a vote at the Seller Shareholders
Meeting or any adjournment thereof, the approval of the Merger by Seller's
shareholders shall not have been obtained as contemplated by Section 5.1;

     (g) by Seller, if prior to the Seller Shareholders Meeting, the Board of
Managers shall have withdrawn or modified its approval or recommendation of the
Merger or this Agreement in connection with, or approved or recommended, a
Superior Acquisition Proposal; and

     (h) by Parent or Buyer if (i) prior to the Seller Shareholders Meeting, the
Board of Managers shall have withdrawn or modified in any manner adverse to
Buyer its approval or recommendation of the Merger or this Agreement in
connection with, or approved or recommended, any Superior Acquisition Proposal,
or (ii) Seller shall have entered into a definitive agreement with respect to
any Acquisition Proposal.

     7.2  Certain Fees and Expenses.  If this Agreement shall be terminated
pursuant to Section 7.1(b), 7.1(g) or 7.1(h), then Seller will pay Buyer (if
Seller was not entitled to terminate this Agreement pursuant to Section 7.1(c)
at the time of such termination) a fee equal to the Seller Break-Up Fee (as
defined below). If this Agreement shall be terminated pursuant to Section
7.1(c), then Buyer will pay Seller (provided Parent and Buyer were not entitled
to terminate this Agreement pursuant to Section 7.1(b) at the time of such
termination) a fee equal to the Buyer Break-Up Fee (as defined below). Any
payment of the Seller Break-Up Fee or the Buyer Break-Up Fee in accordance with
this Section 7.2 shall be compensation for the loss suffered by the recipient as
a result of the failure of the Merger to be consummated and to avoid the
difficulty of determining damages under the circumstances, and neither party
shall have any other liability to the other after the payment of the Seller
Break-Up Fee or the Buyer Break-Up Fee, as applicable. The Seller Break-Up Fee
or the Buyer Break-Up Fee, as applicable, shall be paid in immediately available
funds within fifteen (15) days after the date the event giving rise to the
obligation to make such payment occurred.

     As used in this Agreement, "Seller Break-Up Fee" shall be an amount equal
to the lesser of (i) $4,500,000 (the "Seller Base Amount") and (ii) the sum of
(A) the maximum amount that can be paid to the recipient without causing Parent
or Buyer 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)(A)-(H) and 856(c)(3)(A)-(I) of the Code
("Qualifying Income"), as determined by independent accountants to Parent, and
(B) if Parent receives an opinion from outside counsel (the "Seller Break-Up Fee
Tax Opinion") indicating that Parent's or Buyer's receipt of the Seller Base
Amount would either constitute Qualifying Income or would be excluded from gross
income within the meaning of Sections 856(c)(2) and (3) of the Code (the "REIT
Requirements") or that the receipt by Parent or Buyer of the remaining balance
of the Seller Base Amount following the receipt of and in accordance with such
opinion would not be deemed constructively received prior thereto, the Seller
Base Amount less the amount payable under clause (A) above.

     As used in this Agreement, "Buyer Break-Up Fee" shall be an amount equal to
the lesser of (i) the sum of (x) $4,500,000 plus (y) if the Lend Lease Agreement
is terminated because of a breach by Parent or Buyer hereunder and, as a result
thereof, Seller is obligated to pay Lend Lease Real Estate Investors, Inc. the
fee under Section 7.5 of the Lend Lease Agreement an amount equal to that fee
(the "Buyer Base Amount") and (ii) the sum of (A) the maximum amount that can be
paid to Seller without causing Seller to fail to meet the requirements of
Section 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

                                      B-42
   132

accountants to Seller, and (B) if Seller receives an opinion from outside
counsel (the "Buyer Break-Up Fee Tax Opinion") indicating that Seller's receipt
of the Buyer Base Amount would either constitute Qualifying Income or would be
excluded from gross income within the meaning of the REIT Requirements or that
the receipt by Seller of the remaining balance of the Buyer Base Amount
following the receipt of and pursuant to such opinion would not be deemed
constructively received prior thereto, the Buyer Base Amount less the amount
payable under clause (A) above.

     If the recipient is not able to receive the full Seller Base Amount or the
Buyer Base Amount, as applicable, the payor shall place the unpaid amount in
escrow and shall not release any portion thereof to the recipient unless and
until the payor receives either one of the following: (i) a letter from the
recipient's independent accountants indicating the maximum amount that can be
paid at that time to the recipient without causing the recipient (or Parent, as
applicable) to fail to meet the REIT Requirements or (ii) a Seller Break-Up Fee
Tax Opinion or Buyer Break-Up Fee Tax Opinion, as applicable, in either of which
events the payor shall pay to the recipient the lesser of the unpaid Seller Base
Amount or the Buyer Base Amount, as applicable, or the maximum amount stated
therein.

     7.3  Effect of Termination.  In the event of termination of this Agreement
by either Seller, Parent or Buyer as provided in Section 7.1, this Agreement
shall forthwith become void and have no effect, without any liability or
obligation on the part of Parent, Buyer, or Seller, other than under the last
sentence of Section 5.2, Section 7.2, this Section 7.3 and Article 8.

     7.4  Amendment.  This Agreement may be amended by the parties in writing by
action of their respective Board of Managers and Board of Directors at any time
before or after any shareholder approvals are obtained and prior to the filing
of the Articles of Merger; however, after Seller's shareholders have approved
the Merger, no such amendment, modification or supplement shall be made which by
law requires the further approval of shareholders without obtaining such further
approval. The parties agree to amend this Agreement in the manner provided in
the immediately preceding sentence to the extent required to continue the status
of Seller and Parent as REITs.

     7.5  Extension; Waiver.  At any time prior to the Effective Time, the
parties 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 first sentence of
Section 7.4, waive compliance with any of the agreements of or conditions to be
satisfied by 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. 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.

     8.1  Nonsurvival of Representations and Warranties.  None of the
representations and warranties in this Agreement or in any instrument delivered

Agreement shall survive the Effective Time. This Section 8.1 shall not limit any
covenant or agreement of the parties which by its terms contemplates performance
after the Effective Time.

counterparts, all of which shall be considered one and the same agreement and
shall become effective when one or more counterparts have been signed by each of
the parties and delivered to the other parties.

     8.5  Entire Agreement; No Third-Party Beneficiaries.  This Agreement, the
Schedules and the other agreements entered into in connection with the Merger
(a) constitute the entire agreement and supersede all prior agreements and
understandings, both written and oral, between the parties with respect to the

("Third Party Provisions"), are not intended to confer upon any person other

or obligations of any party under this Agreement shall be assigned or delegated,

court located in Texas or Ohio if any dispute arises out of this Agreement or
any of the transactions contemplated by this Agreement and (b) agrees that it
will not attempt to deny or defeat such personal jurisdiction by motion or other
request for leave from any such court.

     8.9  Severability.  Any term or provision of this Agreement which is
invalid or unenforceable in any jurisdiction shall, as to that jurisdiction, be
ineffective to the extent of such invalidity or unenforceability without
rendering invalid or unenforceable the remaining terms and provisions of this
Agreement or affecting the validity or enforceability of any of the terms or
provisions of this Agreement in any other jurisdiction. If any provision of this
Agreement is so broad as to be unenforceable, the provision shall be interpreted
to be only so broad as is enforceable.

Money to the party hereto entitled to same pursuant to the terms hereof on or
before the tenth (10th) business day following receipt by Escrow Agent and the
non-terminating party of written notice of such termination from the terminating

interpleader shall be assessed against the party against whom judgment is
rendered in the action, or if judgment is rendered in part against both parties,

Subject to the provisions of Section 4.6 hereof, Purchaser or Purchaser's

the Property Information is proprietary and confidential and has been delivered
to Purchaser solely to assist Purchaser in determining the feasibility of
purchasing the Property. Purchaser shall not use the Property Information for
any purpose other than as set forth in the preceding sentence. Purchaser shall
not disclose the contents to any person other than to those persons who are
responsible for determining the feasibility of or are otherwise involved in
Purchaser's acquisition of the Property and who have agreed to preserve the
confidentiality of such information as required hereby (collectively, "Permitted
Outside Parties"). Purchaser shall not divulge the contents of the Property
Information or other information except in strict accordance with the
confidentiality standards set forth in this Section 4.6. In permitting Purchaser
to review the Property Information or any other information, Seller has not
waived any privilege or claim of confidentiality with respect thereto, and no
third party benefits or relationships of any kind, either express or implied,
have been offered, intended or created.

     4.7  No Representation or Warranty by Seller.  Purchaser acknowledges that,
except as expressly set forth in this Agreement, neither Seller nor Asset
Manager has made nor makes any warranty or

                                       C-8
   144

representation regarding the truth, accuracy or completeness of the Property
Information or the source(s) thereof. Purchaser further acknowledges that some
if not all of the Property Information was prepared by third parties other than
Seller and Asset Manager. Except as expressly set forth in this Agreement,
Seller expressly disclaims any and all liability for representations or
warranties, express or implied, statements of fact and other matters contained
in such information, or for omissions from the Property Information, or in any
other written or oral communications transmitted or made available to Purchaser.
Purchaser shall rely solely upon (i) satisfaction of Purchaser's conditions
expressly set forth in this Agreement, (ii) Seller's compliance with the terms
and provisions of this Agreement, and (iii) Purchaser's own investigation with
respect to the Property, including, without limitation, the Property's physical,
environmental or economic condition, compliance or lack of compliance with any
ordinance, order, permit or regulation or any other attribute or matter relating
thereto. Seller has not undertaken any independent investigation as to the
truth, accuracy or completeness of the Property Information.

permit any liens to attach to the Property by reason of the exercise of
Purchaser's rights hereunder; (viii) repair any damage to the Property resulting

disclose prior to Closing any information obtained during Purchaser's inspection
activities with respect to the Property prior to the Effective Date concerning

Outside Parties, in accordance with the confidentiality standards set forth in
Section 4.6 above, or except as may be otherwise required by law.

     4.9  Purchaser's Agreement to Indemnify.  Purchaser indemnifies and holds
Seller and Asset Manager harmless from and against any and all liens, claims,
causes of action, damages, liabilities and expenses (including reasonable
attorneys' fees) arising out of Purchaser's inspections or tests permitted under
this Agreement or the Exclusive Negotiation Agreement between AIP and Lend Lease
Real Estate, Inc. dated June 27, 2000 or any violation of the provisions of
Sections 4.2, 4.6 or 4.8; provided, however, the indemnity shall not extend to
protect Seller from any pre-existing liabilities for matters merely discovered
by Purchaser (e.g., latent environmental contamination) so long as Purchaser's
actions are conducted with reasonable care in accordance with industry
standards. Purchaser's obligations under this Section 4.9 shall survive the
termination of this Agreement and shall survive the Closing.

     4.10  Environmental Studies.  As additional consideration for the
transaction contemplated in this Agreement, Purchaser must provide to Seller,
immediately following the receipt of same by Purchaser, copies of any and all
reports, tests or studies involving contamination of or other environmental
concerns relating to the Property; provided, however, Purchaser shall have no
obligation to cause any such tests or studies to be performed on the Property.
Seller acknowledges that Purchaser has not made and does not make any warranty
or representation regarding the truth or accuracy of any such studies or
reports. Notwithstanding Section 4.9 above, Purchaser shall have no liability or
culpability of any nature as a result of having provided such information to
Seller or as a result of Seller's reliance thereon or arising out of the fact
that Purchaser merely conducted such tests or studies, so long as Purchaser's
actions are conducted with reasonable care in accordance with industry
standards.

                                   ARTICLE 5

                                TITLE AND SURVEY

     5.1  Title Commitment.  Purchaser has caused to be prepared and delivered
to Seller on or before the Effective Date: (i) current commitment(s) for title
insurance or preliminary title report (collectively, the "Title Commitment")
issued by the Title Company, in the aggregate amount of the Purchase Price, with
Purchaser as the proposed insured, and (ii) copies of all documents of record
referred to in the Title Commitment as exceptions to title to the Property.

     5.2  New or Updated Survey.  Purchaser may elect to obtain new surveys or
revise, modify, or re-certify any existing surveys (collectively, the "Survey")
as necessary in order for the Title Company to delete the survey exception from
any title policy (the "Title Policy") Purchaser elects to obtain from the Title
Company or to otherwise satisfy Purchaser's objectives.

     5.3  Title Review.  Prior to the Effective Date, Purchaser has reviewed
title to the Property as disclosed by the Title Commitment and the Survey.
Seller shall have no obligation to cure title objections except financing liens
created by, under or through Seller that are not being assumed by Purchaser,
which liens Seller shall cause to be released at or prior to Closing (with
Seller having the right to apply the Purchase Price or a portion thereof for
such purpose), and Seller shall deliver the Property free and clear of any such
financing liens. Seller further agrees to remove any exceptions or encumbrances
to title which are created by, under or through Seller after the effective date
of each applicable Title Commitment without Purchaser's prior written consent
(if requested, such consent shall not be unreasonably withheld, conditioned or
delayed). The term "Permitted Exceptions" shall mean: the specific exceptions
(excluding exceptions that are part of the applicable promulgated title
insurance form) in the Title Commitment that the Title Company has not agreed to
remove from the Title Commitment as of the Effective Date and that Seller is not
required to remove as provided above; matters created by, through or under
Purchaser; items shown on the Survey; real estate taxes not yet due and payable;
rights of tenants as tenants only under the Leases; and any licensees under any
Service Contracts not terminated as of Closing in accordance with the provisions
hereof.

     5.4  New Exceptions.  Purchaser may have Seller's title to the Property
re-reviewed at any time and from time to time up to the Closing and may give
Seller written notice of any additional title exceptions which first appear of
record after the effective date of each applicable Title Commitment ("New
Exceptions"). Seller shall, if requested by Purchaser, (i) cause any such
exception created by, through or under Seller without Purchaser's written
consent (in its sole discretion) to be removed prior to the Closing and (ii) use
good faith, commercially reasonable efforts to remove any other New Exceptions
prior to the Closing. If any such New Exception is not removed prior to Closing
and will have a material adverse effect on the use and operation of the
applicable Project, in Purchaser's reasonable judgment, Purchaser may elect
either (a) in the case of an exception described in clause (i) above, to close
and receive credit against the Purchase Price equal to the lesser of (A) the
cost of curing such title objection or (B) any diminution in value, determined
by an independent third party appraiser, resulting from or likely to result from
such title objection, or (b) to terminate this Agreement as to the affected
Project, in which event the Purchase Price will be reduced by the allocated
Purchase Price of the affected Project, and the parties shall have no further
rights, duties or obligations hereunder with respect to such Project except for
those obligations which by their terms survive termination of this Agreement. In
addition, if Purchaser elects to terminate this Agreement as to a certain
Project as a result of one or more New Exceptions affecting such Project, and
such affected Project is a part of a cross-collateralized debt pool and the
relevant lender or lenders will not permit such Project to be removed from the
pool at no cost to Purchaser, Purchaser may elect to terminate this Agreement as
to all Properties, in which event the Earnest Money shall be returned to
Purchaser and the parties shall have no further rights, duties or obligations
hereunder except for those obligations which by their terms survive termination
of this Agreement.

                          OPERATIONS AND RISK OF LOSS

     6.1  Ongoing Operations.  From the Effective Date through Closing, Seller
hereby covenants and agrees that:

          6.1.1  Leases Service Contracts and Loan Documents.  Seller will
     perform its material obligations under the Leases, Service Contracts and
     Loan Documents, including payment of all accrued and outstanding tenant
     improvement and leasing commission costs relating to Leases in existence as
     of the Effective Date.

          6.1.2  New Contracts.  Except as provided in Subsection 6.1.4, Seller
     will not enter into any contract that will be an obligation affecting the
     Property subsequent to the Closing, except contracts entered into in the
     ordinary course of business that are terminable without cause and without
     the payment of any termination penalty on not more than thirty (30) days'
     prior notice, and which shall be terminated by Seller at Closing at no cost
     to Purchaser, unless assumed by Purchaser at Purchaser's election made in
     writing to Seller at least ten (10) days prior to Closing.

          6.1.3  Maintenance of Improvements; Removal of Personal
     Property.  Subject to Sections 6.2 and 6.3, Seller shall continue to make
     its budgeted capital expenditures with respect to the Improvements in a
     commercially reasonable manner in the ordinary course of Seller's business
     as provided in the schedule attached hereto as Exhibit H and incorporated
     herein by reference (the "Capital Expenditure Schedule"), and operate and
     maintain the Property in the ordinary course of business and consistent
     with past practice. Seller will not remove any Tangible Personal Property
     except as may be required for necessary repair or replacement, and
     replacement shall be of approximately equal quality and quantity as the
     removed item of Tangible Personal Property.

          6.1.4  Leasing.  Seller will continue to lease space in the
     Improvements in the ordinary course of business; provided Purchaser must
     approve any new Lease and will do so within five (5) business days of
     Seller's delivery of the material terms of any proposed new Lease and
     financial information on the proposed tenant that Seller is permitted to
     share with third parties, or Purchaser's approval thereof shall be deemed
     to have been given. Purchaser shall not unreasonably withhold or delay
     approval of any new Lease. With respect to any new Lease that is approved
     or deemed approved by Purchaser or with respect to the exercise by a tenant
     under an existing Lease of renewal or expansion rights currently provided
     for in the applicable Lease which renewal or expansion becomes effective
     after the Effective Date, Purchaser shall be responsible for all third
     party tenant improvement and leasing commission costs associated with such
     new Lease, renewal or expansion. For purposes hereof, a "new Lease" shall
     also mean a renewal of an existing Lease or expansion of space covered by
     an existing Lease that is not currently provided for in the Lease documents
     evidencing the existing Lease.

          6.1.5  Maintenance of Insurance.  Seller shall maintain the property
     insurance currently in effect with respect to the Property through the last
     day prior to the Closing Date at no cost to Purchaser.

     6.2  Damage.  If prior to Closing any Project is damaged by fire or other
casualty, Seller shall promptly notify Purchaser of the casualty and estimate
the cost to repair and the time required to complete repairs and will provide
Purchaser written notice of Seller's estimation (the "Casualty Notice") as soon
as reasonably possible after the occurrence of the casualty.

          6.2.1  Material.  In the event of any Material Damage to or
     destruction of at least four (4) Projects or any portion of at least four
     (4) Projects prior to Closing, Purchaser may, at its option, terminate this
     Agreement as to either all of the affected Projects or all of the
     Properties by delivering written notice to Seller on or before the
     expiration of thirty (30) days after the date Seller delivers the Casualty
     Notice to Purchaser (and if necessary, the Closing Date shall be extended
     to give the parties the full thirty-day period to make such election and to
     obtain insurance settlement agreements with Seller's insurers). Upon any
     termination as to the affected Projects instead of all of the Properties,
     the Purchase Price shall be reduced by the allocated portion of the
     Purchase Price for the
                                      C-11
   147

     applicable Projects, and the parties hereto shall have no further rights or
     obligations hereunder as to the affected Projects, other than those that by
     their terms survive the termination of this Agreement. If Purchaser elects
     to terminate as to all of the Properties, the Earnest Money shall be
     returned to Purchaser and the parties shall have no further rights, duties
     or obligations hereunder except for the obligations which by their terms
     survive termination of this Agreement. Notwithstanding the foregoing, in
     the event Purchaser elects to terminate this Agreement as to four (4) or
     more Projects due to Material Damage occurring to the Properties, Seller
     shall have the option to terminate this Agreement as to all Properties, in
     which event the Earnest Money shall be returned to Purchaser and the
     parties shall have no further rights, duties or obligations hereunder
     except for the obligations which by all of the terms survive termination of
     this Agreement. In the event of Material Damage or destruction of three (3)
     or fewer Projects or if Purchaser elects not to terminate this Agreement as
     to at least four (4) affected Projects as detailed above within said thirty
     (30) day period, then the parties shall proceed under this Agreement and
     close on schedule, and as of Closing Seller shall assign to Purchaser,
     without representation or warranty by or recourse against Seller, all of
     Seller's rights in and to any resulting insurance proceeds (including any
     rent loss insurance applicable to any period on and after the Closing Date)
     due Seller as a result of such damage or destruction, Purchaser shall
     assume full responsibility for all needed repairs, and Purchaser shall
     receive a credit at Closing for any deductible amount under such insurance
     policies. For the purposes of this Agreement, "Material Damage"and
     "Materially Damaged" means damage which, in Seller's reasonable estimation,
     exceeds $500,000.00 to repair or which, in Seller's reasonable estimation,
     will take longer than ninety (90) days to repair.

          6.2.2  Not Material.  If any Project is damaged but not Materially
     Damaged, then neither Purchaser nor Seller shall have the right to
     terminate this Agreement as to the affected Project, and Seller shall, at
     its option, either (i) repair the damage before the Closing in a manner
     reasonably satisfactory to Purchaser, or (ii) assign to Purchaser all of
     Seller's proceeds from insurance payable by reason of such damage, plus pay
     an amount to Purchaser for any deductible, less any amount expended by
     Seller for repairs made with Purchaser's approval (in which case Purchaser
     shall assume full responsibility for all needed repairs).

     6.3  Condemnation.  If proceedings in eminent domain are instituted with
respect to any Project comprising the Property or any portion thereof which
involves the taking of a portion of the Property exceeding $500,000.00 in value,
Purchaser and Seller shall have the same rights and obligations as provided in
Subsection 6.2.1 with respect to a casualty event affecting the Property.
Provided, if Purchaser is obligated or, if applicable, elects to proceed under
this Agreement, Seller shall, at the Closing, assign to Purchaser its entire
right, title and interest in and to any condemnation award, and Purchaser shall
have the sole right after the Closing to negotiate and otherwise deal with the
condemning authority in respect of such matter.

preliminary proxy statement in accordance with the applicable rules and
regulations promulgated under the Securities Exchange Act of 1934 and thereafter
shall file as soon as is practicable a definitive proxy statement. The proxy
statement shall include a proposal to approve the transactions contemplated in
this Agreement (the "Shareholder Proposal") and shall include the recommendation
of AIP's Board of Trust Managers in favor of the proposal. Seller shall use good
faith and commercially reasonable efforts to respond to any comments of the SEC

as practicable. Purchaser shall furnish all information concerning Purchaser as
AIP may reasonably request in connection with such actions and the preparation
of the proxy statement.

     7.3  Manhattan Towers.  In connection with the transactions contemplated by
this Agreement, Seller is attempting to sell as a project owned by Seller known
as the Manhattan Towers Project and located in Manhattan Beach, California (the

to cause the sale of the Manhattan Towers Project to occur on such terms and
prior to or contemporaneously with Closing.

contemporaneously with Closing.

     7.5  Break Up Fee; Reimbursement.  If (i) notwithstanding Seller's good
faith efforts, Seller does not (A) obtain Shareholder Approval on or before the

of the fiduciary obligations of the board of trust managers of AIP, as
determined in good faith in consultation with outside counsel, Seller determines
to, and does, terminate this Agreement (which Seller shall hereby be entitled to
do); or (iii) the transactions contemplated by this Agreement are not
consummated because the conditions set forth in Section 9.2 are not satisfied as
a result of a default by Seller hereunder; or (iv) Seller does not obtain
Shareholder Approval on or before the Outside Closing Date, Seller shall pay to
Purchaser a break up fee of $3,000,000.00, and will reimburse Purchaser for the

incurred by Purchaser or its affiliates, including Lend lease Real Estate
Investments, Inc., in connection with the transactions contemplated by this
Agreement, not to exceed $450,000.00 in the aggregate. Seller agrees to make the
election to terminate or not terminate this Agreement due to a termination of
AIP's merger agreement with DDR outlined in (C) above within fourteen (14) days

deemed to have elected to waive such termination right and proceed to Closing
under the remaining applicable terms and conditions specified in this Agreement.
This Section 7.5 shall survive termination of this Agreement.

          (a) neither it nor any officer, director, employee, representative,
     advisor or agent of Seller or any business entity under its direct control
     (collectively, the "Subsidiaries") shall initiate, solicit or knowingly
     encourage, directly or indirectly, any inquiries or the making or
     implementation of any proposal or offer (including, without limitation, any
     proposal or offer to its shareholders) with respect to a merger,
     acquisition, tender offer, exchange offer, consolidation, sale of assets or
     similar transaction involving all or any significant portion of the assets
     or equity securities of Seller or any of

                                      C-13
   149

     the Subsidiaries, other than the transactions contemplated by this
     Agreement, the DDR merger agreement and the Manhattan Towers agreement (any
     such proposal or offer being hereinafter referred to as an "Acquisition
     Proposal") or engage in any negotiations concerning or provide any
     confidential information or data to, or have any discussions with, any
     person relating to an Acquisition Proposal, or otherwise facilitate any
     effort or attempt to make or implement an Acquisition Proposal;

          (b) it shall direct and use its reasonable best efforts to cause its
     officers, board of trust managers, employees, agents and financial advisors
     not to engage in any of the activities described in Section 7.6(a) except
     to the extent expressly permitted by the proviso below;

          (c) it will immediately cease and cause to be terminated any existing
     activities, discussions or negotiations with any parties conducted
     heretofore with respect to any of the foregoing; and

          (d) it will notify Purchaser promptly if Seller receives any such
     inquiries or proposals, or any requests for such information, or if any
     such negotiations or discussions are sought to be initiated or continued
     with it;

        provided, however, that nothing contained in this Agreement shall
        prohibit the board of trust managers of AIP (or the officers, board of
        trust managers of AIP, employees, agents or financial advisors of Seller
        acting at the direction of the board of trust of managers of AIP) from
        (i) furnishing information to or entering into discussions or
        negotiations with, any person or entity that makes an unsolicited
        Acquisition Proposal, if, and only to the extent that (x) the board of
        trust managers of AIP determines in good faith following consultation
        with counsel and with Seller's financial advisors that such action is
        required for the board of trust managers of AIP to comply with its
        duties to shareholders imposed by law or such proposal is a Superior
        Acquisition Proposal (as hereinafter defined), (y) prior to furnishing
        such information to, or entering into discussions or negotiations with,
        such person or entity, Seller provides written notice to Purchaser to
        the effect that it is furnishing information to, or entering into
        discussions with, such person or entity, and (z) subject to any
        confidentiality agreement with such person or entity, Seller keeps
        Purchaser informed of the status (not the terms) of any such discussions
        or negotiations; or (ii) to the extent applicable, taking and disclosing
        to Seller's shareholders a position contemplated by Rules 14d-9 and
        14e-2 promulgated under the Exchange Act with regard to an Acquisition
        Proposal. Nothing in this Section 7.6 shall (1) permit Seller to
        terminate this Agreement (except as specifically provided in Article 7
        hereof), (2) permit Seller to enter into an agreement with respect to an
        Acquisition Proposal during the term of this Agreement (other than a
        confidentiality agreement in customary form executed as provided above)
        or (3) affect any other obligation of Seller under this Agreement;
        provided, however, that the board of trust managers of AIP may, subject
        to the provisions of Section 7.5, approve and recommend a Superior
        Acquisition Proposal and, in connection therewith, withdraw or modify
        its approval or recommendation of this Agreement. Any disclosure that
        the board of trust managers of AIP may be compelled to make with respect
        to the receipt of an Acquisition Proposal in order to comply with its
        duties to shareholders of Seller or comply with applicable law will not
        constitute a violation of this Section 7.6. As used herein, "Superior
        Acquisition Proposal" means a bona fide Acquisition Proposal made by a
        third party which the board of trust managers of AIP (or a duly
        constituted committee thereof charged with considering Acquisition
        Proposals) determines in good faith following consultation with counsel
        and with Seller's financial advisors to be more favorable to Seller's
        shareholders from a financial point of view than the transactions
        contemplated herein and which the board of trust managers of AIP (or any
        such committee) determines is reasonably capable of being financed and
        consummated.

subject to the Existing Loans, subject to the limitations on recourse set forth
in the documents evidencing or securing such loans, in which case Purchaser
shall assume such Existing Loans at Closing; or (ii) the Existing Loans shall be
paid at Closing. Purchaser agrees to promptly notify Seller of Purchaser's
election to not assume any Existing Loan for which Purchaser's assumption has

good faith and use their commercially reasonable efforts to negotiate with the
relevant lenders prior to the Closing Date to: (i) obtain the required lender
consents to Purchaser's proposed assumptions; (ii) minimize prepayment and

     which indemnification obligation shall survive the Closing.

          10.1.2  Utilities.  Purchaser and Seller shall take all steps
     necessary to effectuate the transfer of all utilities to Purchaser's name
     as of the Closing Date, and where necessary, Purchaser shall post deposits
     with the utility companies. Seller shall ensure that all utility meters are
     read as of the Closing Date. Seller shall be entitled to recover any and
     all deposits held by any utility company as of the Closing Date.

          10.1.3  Tenant Receivables.  Rents due from tenants under Leases and
     operating expenses and/or taxes payable by tenants under Leases
     (collectively, "Tenant Receivables") shall be

                                      C-18
   154

     apportioned on the basis of the period for which the same is payable and
     if, as and when collected, as follows:

             (a) Purchaser shall apply rent and other income received from
        tenants under Leases after Closing in the following order of priority:
        (i) first, to payment of the current Tenant Receivables then due for the
        month in which the Closing Date occurs, which amount shall be
        apportioned between Purchaser and Seller as of the Closing Date as set
        forth in Section 10.1 hereof (with Seller's portion thereof to be
        delivered to Seller); (ii) second, to Tenant Receivables first coming
        due after Closing and applicable to the period of time after Closing,
        which amount shall be retained by Purchaser; (iii) third, to payment of
        Tenant Receivables first coming due after Closing but applicable to the
        period of time before Closing, including, without limitation, the Tenant
        Receivables described in Subsection 10.1.3(b) below (collectively,
        "Unbilled Tenant Receivables"), which amount shall be delivered to
        Seller; and (iv) thereafter, to delinquent Tenant Receivables which were
        due and payable as of Closing but not collected by Seller as of Closing
        (collectively, "Uncollected Delinquent Tenant Receivables"), which
        amount shall be delivered to Seller. Notwithstanding the foregoing,
        Seller shall have the right to pursue the collection of Uncollected
        Delinquent Tenant Receivables for a period of one (1) year after Closing
        without prejudice to Seller's rights or Purchaser's obligations
        hereunder, provided, however, Seller shall have no right to cause any
        such tenant to be evicted or to exercise any other remedies set forth in
        such tenant's Lease against such tenant other than to sue for
        collection. Any sums received by Purchaser to which Seller is entitled
        shall be held in trust for Seller on account of such past due rents
        payable to Seller, and Purchaser shall remit to Seller any such sums
        received by Purchaser to which Seller is entitled within ten (10)
        business days after receipt thereof less reasonable, actual costs and
        expenses of collection, including reasonable attorneys' fees, court
        costs and disbursements, if any. Seller expressly agrees that if Seller
        receives any amounts after the Closing Date which are attributable, in
        whole or in part, to any period after the Closing Date, Seller shall
        remit to Purchaser that portion of the monies so received by Seller to
        which Purchaser is entitled within ten (10) business days after receipt
        thereof. With respect to Unbilled Tenant Receivables, Purchaser
        covenants and agrees to (A) bill the same when billable pursuant to the
        applicable Lease and (B) cooperate with Seller to determine the correct
        amount of operating expenses and/or taxes due pursuant to the applicable
        Lease. The provisions of this Subsection 10.1.3(a) shall survive the
        Closing.

             (b) Without limiting the generality of the requirements of
        Subsection 10.1.3(a)(ii) above, if the final reconciliation or
        determination of operating expenses and/or taxes due under the Leases
        shows that a net amount is owed by Seller to Purchaser, Purchaser's pro
        rata portion shall be paid by Seller to Purchaser within ten (10)
        business days of such final determination under the Leases. If the final
        determination of operating expenses and/or taxes due under the Leases
        shows that a net amount is owed by Purchaser to Seller, Purchaser shall,
        within ten (10) business days of such final determination, remit to
        Seller Seller's portion of operating expenses and/or taxes for the
        period up to and including the Closing Date, if, as and when received.
        Purchaser agrees to receive and hold any monies received on account of
        such past due expenses and/or taxes in trust for Seller and to pay same
        promptly to Seller as aforesaid. The provisions of this Subsection
        10.1.3(b) shall survive the Closing.

     10.2  Closing Costs.  Closing costs shall be allocated between Seller and
Purchaser in accordance with Section 1.2.

     10.3  Capital Expenditures.  To the extent Seller did not fund all capital
expenditures scheduled to be performed on or before the Closing Date (as set
forth on the Capital Expenditure Schedule), Purchaser shall receive a credit
against the Purchase Price in the estimated amount of such unfunded capital
expenditures, as shown on the Capital Expenditure Schedule.

     10.4  Final Adjustment After Closing.  If final bills are not available or
cannot be issued prior to Closing for any item being prorated under Section
10.1, then Purchaser and Seller agree to allocate such
                                      C-19
   155

items on a fair and equitable basis as soon as such bills are available, final
adjustment to be made as soon as reasonably possible after the Closing. Payments
in connection with the final adjustment shall be due within thirty (30) days of
written notice. All such rights and obligations shall survive the Closing.

     10.5  Tenant Deposits.  All tenant security deposits collected and not
applied by Seller in accordance with the terms of the applicable Lease and
applicable law (and interest thereon if required by law or contract) shall be
transferred or credited to Purchaser at Closing. As of the Closing, Purchaser
shall assume Seller's obligations related to tenant security deposits, but only
to the extent they are credited or transferred to Purchaser.

     10.6  No Commissions.  Seller and Purchaser each represent and warrant to
the other that no real estate brokerage commission is payable to any person or
entity in connection with the transaction contemplated hereby, and each agrees
to and does hereby indemnify and hold the other harmless against the payment of
any commission to any other person or entity claiming by, through or under
Seller or Purchaser, as applicable. This indemnification shall extend to any and
all claims, liabilities, costs and expenses (including reasonable attorneys'
fees and litigation costs) arising as a result of such claims and shall survive
the Closing.

          11.1.1  Organization and Authority.  Each entity comprising "Seller"
     has been duly organized, is validly existing, and is in good standing in
     the state in which it was formed. Subject to Shareholder Approval, Seller
     has the full right and authority to enter into this Agreement and to
     consummate or cause to be consummated the transactions contemplated hereby.
     This Agreement has been, and all of the documents to be delivered by Seller
     at the Closing will be, authorized and executed and constitute, or will
     constitute, as appropriate, the valid and binding obligation of Seller,
     enforceable in accordance with their terms, subject to the Shareholder
     Approval. Except as disclosed by Seller to Purchaser, the execution,
     delivery, and performance of this Agreement and the Closing Documents by
     Seller will not result in any violation of or default under, or require any
     notice, or consent under any of Seller's organizational documents, any
     other agreement to which Seller is a party or any law, judgment or order
     applicable to Seller.

          11.1.2  Conflicts and Pending Actions.  Except as disclosed by Seller
     to Purchaser, there is no agreement to which Seller is a party or, to
     Seller's knowledge, that is binding on Seller which is in conflict with
     this Agreement. There is no action or proceeding pending or, to Seller's
     knowledge, threatened against Seller or relating to the Property, which
     challenges or impairs Seller's ability to execute or perform its
     obligations under this Agreement, and no order or other relief has been
     entered that imposes any recorded lien or other encumbrance on any of the
     Property.

          11.1.3  Service Contracts.  To Seller's knowledge, the list of Service
     Contracts to be delivered to Purchaser pursuant to this Agreement will be
     correct and complete as of the date of its delivery.

          11.1.4  Notices from Governmental Authorities.  To Seller's knowledge,
     Seller has not received from any governmental authority written notice of
     any material violation of any laws applicable (or alleged to be applicable)
     to the Property, or any part thereof, that has not been corrected, except
     as may be reflected by the Property Information.

          11.1.5  Leases.  On or prior to the Effective Date, Seller has
     delivered to Purchaser or made available to Purchaser, true, and correct

     K, attached hereto and incorporated herein by this reference (the
     "Commission Schedule"). Seller has delivered to the Purchaser or made
     available to Purchaser true and correct and complete copies of all existing
     Leases. The Commission Schedule lists tenant improvement costs, brokers'
     commissions and leasing fees for
                                      C-20

     any tenant's prior space for which the landlord with respect to any of the
     Properties is obligated or subject and which are unpaid as of October 6,
     2000, and (ii) all brokers' commissions and leasing fees which the landlord
     with respect to any of the Properties is contractually obligated to pay in
     the event any tenant exercises any renewal or expansion option.

        As of the Effective Date, no Lease has been modified except as shown in
        the Leases delivered to Purchaser. Each of the Leases is in full force
        and effect. To Seller's knowledge, no uncured event of material default
        on the part of Seller has occurred under any of the Leases and there
        exists no event which, with the giving of notice or the passage of time,
        or both, would constitute such a default. To Seller's knowledge, no
        uncured event of material default on the part of any tenant has occurred
        under any of the Leases and, to Seller's knowledge, there exists no
        event which, with the giving of notice or the passage of time, or both,
        would constitute such a default. No tenant has any defense, offset or
        claim against its obligation to pay rent or perform any of its other
        obligations under its Lease. Except with respect to the "Battlefield
        Property," no tenant has any right of right or first refusal or option
        to purchase any part of the Property. If the tenant at the Battlefield
        Property does elect to exercise its purchase option, the Battlefield
        Property shall no longer be subject to this Agreement and the Purchase
        Price will be reduced by the allocated Purchase Price thereof provided
        pursuant to a separate written agreement between Seller and Purchaser
        and the parties shall have no further rights, duties or obligations
        herewith respect to the Battlefield Property, except for those
        obligations which by their terms survive termination of this Agreement.

     delivered to the Purchaser or made available to Purchaser true and correct
     and complete copies of all existing Loan Documents. The Loan Documents have
     not been modified except as shown in the Loan Documents. There are no other
     documents or instruments which evidence, secure or otherwise govern the
     Existing Loans. Seller has not received any notice of any material breach
     or material default under the Loan Documents, and to Seller's knowledge,
     there is no existing or uncured material default or material breach by any
     party under the Loan Documents, and no facts or circumstances exist that,
     with the passage of time or the giving of notice, or both, would constitute
     such a default or breach by any party under the Loan Documents. To Seller's
     knowledge, the current mortgagees or beneficiaries of the Existing Loans
     are the lenders identified on Exhibit F. The outstanding principal balance
     of each of the Existing Loans estimated as of February 28, 2001 is set
     forth on Exhibit F.

          11.1.7  Service Contracts.  On or prior to the Effective Date, Seller

     breach or material default under the Service Contracts, and to Seller's
     knowledge, there is no existing or uncured material default or material
     breach by any party under the Service Contracts, and no facts or
     circumstances exist that, with the passage of time or the giving of notice,
     or both, would constitute a default or breach by any party under the
     Service Contracts.

     under the management agreements, and to Seller's knowledge, there is no
     existing or uncured material default or material breach by any party under

     a default or breach by any party under the management agreements.

     Properties.

     11.2  Purchaser's Representations and Warranties.  Purchaser represents and
warrants to Seller that:

          11.2.1  Organization and Authority.  Purchaser has been duly organized
     and is validly existing as a limited partnership in good standing in the
     State of Georgia and as of the Closing Date will be qualified to do
     business in each state in which the Real Property is located. Purchaser has

     the transactions contemplated hereby. This Agreement has been, and all of
     the documents to be delivered by Purchaser at the Closing will be,
     authorized and properly executed and constitute, or will constitute, as
     appropriate, the valid and binding obligation of Purchaser, enforceable in
     accordance with their terms. The execution, delivery, and performance of
     this Agreement and the Closing Documents by Purchaser will not result in
     any violation of or default under, or require any notice, or consent under
     any of Purchaser's organizational documents, any other agreement to which
     Purchaser is a party or any law, judgment or order applicable to Purchaser.

          11.2.2  Conflicts and Pending Action.  There is no agreement to which

     11.3  Survival of Representations and Warranties.  The representations and
warranties set forth in this Article 11 are made as of the date of this
Agreement and remade as of the Closing Date, but shall be deemed to be merged
into and waived by the instruments of Closing, and shall not survive the
Closing. Terms such as "to Seller's knowledge," "to the best of Seller's
knowledge," or like phrases do not include constructive knowledge, imputed
knowledge, or knowledge Seller does not have but could have obtained through
further investigation or inquiry. Terms such as "to Purchaser's knowledge," "to
the best of Purchaser's knowledge," or like phrases do not include constructive

this Agreement and recover the Earnest Money as liquidated damages and not as

estimate of those damages which has been agreed to in an effort to cause the
amount of such damages to be certain. Notwithstanding anything in this Section

this Agreement, Seller shall have all remedies available at law or in equity in
the event Purchaser or any party related to or affiliated with Purchaser is
asserting any claims or right to the Property that would delay or prevent Seller
from having clear, indefeasible and marketable title to the Property. In all
other events Seller's remedies shall be limited to those described in this
Section 12.1 and Sections 4.9, 10.6, 12.3 and 12.4 hereof. IN NO EVENT SHALL
PURCHASER'S DIRECT OR INDIRECT PARTNERS, SHAREHOLDERS, OWNERS OR AFFILIATES, ANY
OFFICER, DIRECTOR, EMPLOYEE OR AGENT OF THE FOREGOING, OR ANY AFFILIATE OR
CONTROLLING PERSON THEREOF HAVE ANY LIABILITY FOR ANY CLAIM, CAUSE OF ACTION OR
OTHER LIABILITY ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE PROPERTY,
WHETHER BASED ON CONTRACT, COMMON LAW, STATUTE, EQUITY OR OTHERWISE.

giving Seller timely written notice of such election prior to or at Closing and
recover the amounts specified under Section 7.5, or (ii) waive said failure or
breach and proceed to Closing. IN NO EVENT SHALL SELLER'S DIRECT OR INDIRECT

Purchaser from and against any and all costs, losses, liabilities, obligations,
damages, lawsuits, deficiencies, claims, demands and expenses, including without
limitation attorney's fees and all amounts paid in investigation, defense or
settlement of any of the foregoing, incurred in connection with, arising out of,
or resulting from any litigation against Seller, including without limitation,
any shareholder litigation arising as a result of the transactions contemplated
by this Agreement, but excluding any such item arising out of Purchaser's

real property. There is a possibility that a release of a hazardous substance
may have come to be located on or beneath one or more of the Projects as

     (c) Purchaser acknowledges that "Natural Hazards" described in the
following California Code Sections (the "Natural Hazard Laws") may affect one or
more of the Projects: Government Code Section 8589.3 (Special Flood Hazard);
Government Code Section 8589.5 (Potential Flooding); Government Code Sections
51178 and 51179 (Very High Fire Hazard Severity Zone); Public Resources Code
Section 2622 (Earthquake Fault Zone); Public Resources Code Section 2696

Purchaser's Initials /s/ JR

     13.3  Seller Released from Liability.  Purchaser acknowledges that it had
the opportunity to inspect the Property prior to the Effective Date, and during
such period, observe its physical characteristics and existing conditions and
the opportunity to conduct such investigation and study on and of the Property
and adjacent areas as Purchaser deems necessary, and Purchaser hereby FOREVER
RELEASES AND DISCHARGES Seller and Asset Manager from all responsibility and
liability to Purchaser, including without limitation, liabilities under the
Comprehensive Environmental Response, Compensation and
                                      C-25
   161

Liability Act Of 1980 (42 U.S.C. Sections 9601 et seq.), as amended ("CERCLA"),
California Health and Safety Code Sections 25300, et seq. and other similar
applicable state laws, directly or indirectly, regarding the condition
(including the presence in the soil, air, structures and surface and subsurface
waters, of Hazardous Materials or other materials or substances that have been
or may in the future be determined to be toxic, hazardous, undesirable or
subject to regulation and that may need to be specially treated, handled and/or
removed from the Property under current or future federal, state and local laws,
regulations or guidelines), valuation, salability or utility of the Property, or
its suitability for any purpose whatsoever; provided, however, the foregoing
release shall not include third party claims brought against Purchaser for which
Seller may be liable otherwise than under this Agreement. By closing this
transaction, Purchaser will be deemed to have waived any and all objections to
or complaints regarding (including, but not limited to, federal, state and
common law based actions), or any private right of action under, state and
federal law to which the Property is or may be subject, including, but not
limited to, CERCLA, physical characteristics and existing conditions, including,
without limitation, structural and geologic conditions, subsurface soil and
water conditions and solid and hazardous waste and Hazardous Materials on,
under, adjacent to or otherwise affecting the Property. Purchaser further hereby
assumes the risk of changes in applicable laws and regulations relating to past,
present and future environmental conditions on the Property and the risk that
adverse physical characteristics and conditions, including, without limitation,
the presence of Hazardous Materials or other contaminants, may not have been
revealed by its investigation. Purchaser expressly waives the provisions of
Section 1542 of the California Civil Code (or any similar provision or principle
of law which may apply in any other state where any Property is located) which
provides:

        "A GENERAL RELEASE DOES NOT EXTEND TO CLAIMS WHICH THE CREDITOR
        DOES NOT KNOW OR EXPECT TO EXIST IN HIS FAVOR AT THE TIME OF
        EXECUTING THE RELEASE, WHICH IF KNOWN TO HIM MUST HAVE
        MATERIALLY AFFECTED THE SETTLEMENT WITH THE DEBTOR."

        Purchaser's Initials: /s/ JR

     13.4  "Hazardous Materials" Defined.  For purposes hereof, "Hazardous
Materials" means "Hazardous Material," "Hazardous Substance," "Hazardous Waste,"
"Extremely Hazardous Waste," "Restricted Hazardous Waste," "Pollutant or
Contaminant," and "Petroleum" and "Natural Gas Liquids," as those terms are
defined or used in Section 101 of CERCLA or under any laws, ordinances, rules,
requirements and regulations of any governmental authority having jurisdiction
with respect to the Property, and any other substances regulated because of
their effect or potential effect on public health and the environment,
including, without limitation, PCBs, lead paint, asbestos, urea formaldehyde,
radioactive materials, putrescible, petroleum and infectious materials.

     13.5  Indemnity.  Purchaser agrees to indemnify and hold Seller harmless of
and from any and all liabilities, claims, demands, and expenses of any kind or
nature which arise or accrue after Closing and relate to the ownership,
maintenance, or operation of the Property by Purchaser and its successors and
assigns, including, without limitation, in connection with Hazardous Materials
at, on or under the Property, but excluding any matters as to which Seller has
contractual liability. Such indemnity shall not apply to any Hazardous Materials
existing as of the Closing Date unless Purchaser's activities cause the release
and/or migration of any Hazardous Materials at, on or under the Property
existing as of the Closing Date.

     13.6  Survival.  The terms and conditions of this Article 13 shall
expressly survive the Closing, and not merge with the provisions of any closing
documents.

     Purchaser acknowledges and agrees that the disclaimers and other agreements
set forth herein are an integral part of this Agreement and that Seller would
not have agreed to sell the Property to Purchaser for the Purchase Price without
the disclaimers and other agreements set forth above.

                                 MISCELLANEOUS

     14.1  Parties Bound; Assignment.  This Agreement, and the terms, covenants,
and conditions herein contained, shall inure to the benefit of and be binding
upon the heirs, personal representatives, successors, and assigns of each of the
parties hereto. Purchaser may assign its rights under this Agreement to one or
more assignees upon the following conditions: (i) the Assignee of Purchaser must

or an entity in which Value Enhancement Fund IV, L.P. is a direct or indirect

confirmed in writing within 24 hours) promptly following Purchaser's designation

and assumption agreement shall be delivered to Seller at least five (5) days
prior to Closing.

     14.2  Headings.  The article, section, subsection, paragraph and/or other
headings of this Agreement are for convenience only and in no way limit or
enlarge the scope or meaning of the language hereof.

     14.3  Invalidity and Waiver.  If any portion of this Agreement is held
invalid or inoperative, then so far as is reasonable and possible the remainder
of this Agreement shall be deemed valid and operative, and, to the greatest
extent legally possible, effect shall be given to the intent manifested by the
portion held invalid or inoperative. The failure by either party to enforce
against the other any term or provision of this Agreement shall not be deemed to
be a waiver of such party's right to enforce against the other party the same or
any other such term or provision in the future.

     14.4  Governing Law.  This Agreement shall, in all respects, be governed,
construed, applied, and enforced in accordance with the law of the State of
Texas.

     14.5  Survival.  The provisions of this Agreement that contemplate
performance after the Closing and the obligations of the parties not fully
performed at the Closing shall survive the Closing and shall not be deemed to be
merged into or waived by the instruments of Closing.

     14.6  Entirety and Amendments.  This Agreement embodies the entire
agreement between the parties and supersedes all prior agreements and
understandings relating to the Property. This Agreement may be amended or
supplemented only by an instrument in writing executed by the party against whom
enforcement is sought.

     14.7  Time.  Time is of the essence in the performance of this Agreement.

     14.8  Confidentiality.  Purchaser shall make no public announcement or
disclosure of any information related to this Agreement to outside brokers or
third parties, before or after the Closing, without the prior consent of Seller;
provided, however, that Purchaser may, subject to the provisions of Section 4.6,
make disclosure of this Agreement to its Permitted Outside Parties as necessary
to perform its obligations hereunder and as may be required under laws or
regulations applicable to Purchaser. Notwithstanding anything to the contrary
hereinafter set forth, Purchaser may disclose such information (i) to its
employees, members of professional firms serving it or potential lenders or
investors who need such information for purposes of evaluating the transactions
contemplated in this Agreement, provided any such persons or entities agree to
and shall maintain the confidentiality thereof, (ii) if any court or
governmental agency requires disclosure in order to comply with applicable laws,
(iii) pursuant to any legal requirement, any reporting requirement pursuant to
applicable law or the applicable rules by any securities exchange or any
accounting or auditing disclosure requirement, (iv) in any legal action, to the
extent necessary to enforce its rights under this Agreement, and (v) to the
extent that such information is a matter of public record. The provisions of
this Section 14.8 shall survive the termination of this Agreement.

     14.9  Notices.  All notices required or permitted hereunder shall be in
writing and shall be served on the parties at the addresses set forth in Section
1.3. Any such notices shall, unless otherwise provided
                                      C-27
   163

herein, be given or served (i) by depositing the same in the United States mail,
postage paid, certified and addressed to the party to be notified, with return
receipt requested, (ii) by overnight delivery using a nationally recognized
overnight courier, (iii) by personal delivery, or (iv) by facsimile, evidenced
by confirmed receipt. Notice deposited in the mail in the manner hereinabove
described shall be effective on the third (3rd) business day after such deposit.
Notice given in any other manner shall be effective only if and when received by
the party to be notified. A party's address may be changed by written notice to
the other party; provided, however, that no notice of a change of address shall
be effective until actual receipt of such notice. Copies of notices are for
informational purposes only, and a failure to give or receive copies of any
notice shall not be deemed a failure to give notice. Notices given by counsel to
the Purchaser shall be deemed given by Purchaser and notices given by counsel to
the Seller shall be deemed given by Seller.

     14.10  Construction.  The parties acknowledge that the parties and their
counsel have reviewed and revised this Agreement and agree that the normal rule
of construction -- to the effect that any ambiguities are to be resolved against
the drafting party -- shall not be employed in the interpretation of this
Agreement or any exhibits or amendments hereto.

     14.11  Calculation of Time Periods.  Unless otherwise specified, in
computing any period of time described herein, the day of the act or event after
which the designated period of time begins to run is not to be included and the
last day of the period so computed is to be included, unless such last day is a
Saturday, Sunday or legal holiday for national banks in the location where the
Property is located, in which event the period shall run until the end of the
next day which is neither a Saturday, Sunday, or legal holiday. The last day of
any period of time described herein shall be deemed to end at 5:00 p.m. Central
Standard Time.

     14.12  Execution in Counterparts.  This Agreement may be executed in any
number of counterparts, each of which shall be deemed to be an original, and all
of such counterparts shall constitute one Agreement. To facilitate execution of
this Agreement, the parties may execute and exchange by telephone facsimile
counterparts of the signature pages, provided that executed originals thereof
are forwarded to the other party on the same day by any of the delivery methods
set forth in Section 14.9 other than facsimile.

     14.13  No Recordation.  Without the prior written consent of Seller, there
shall be no recordation of either this Agreement or any memorandum hereof, or
any affidavit pertaining hereto, and any such recordation of this Agreement or
memorandum or affidavit by Purchaser without the prior written consent of Seller
shall constitute a default hereunder by Purchaser, whereupon Seller shall have
the remedies set forth in Section 12.1 hereof.

     14.14  Further Assurances.  In addition to the acts and deeds recited
herein and contemplated to be performed, executed and/or delivered by either
party at Closing, each party agrees to perform, execute and deliver, but without
any obligation to incur any additional liability or expense, on or after the
Closing any further deliveries and assurances as may be reasonably necessary to
consummate the transactions contemplated hereby or to further perfect the
conveyance, transfer and assignment of the Property to Purchaser.

     14.15  Discharge of Obligations.  The acceptance of the Deed by Purchaser
shall be deemed to be a full performance and discharge of every representation
and warranty made by Seller herein and every agreement and obligation on the
part of Seller to be performed pursuant to the provisions of this Agreement,
except those which are herein specifically stated to survive Closing.

     14.16  No Third Party Beneficiary.  The provisions of this Agreement and of
the documents to be executed and delivered at Closing are and will be for the
benefit of Seller and Purchaser only and are not for the benefit of any third
party, and accordingly, no third party shall have the right to enforce the
provisions of this Agreement or of the documents to be executed and delivered at
Closing.

     14.17  Asset Manager: Designated Representative.  Seller has engaged the
companies listed on Exhibit G (collectively, "Asset Manager") to provide certain
asset management services with respect to the Property. One of the Asset
Managers, Chase Realty Advisors, Inc. ("Chase") has been engaged to act as a
liaison between Seller and Purchaser in connection with the Property and this
Agreement. Chase has
                                      C-28
   164

appointed Stan Levy and Tom Grier ("Designated Representative(s)") to deal with
Purchaser. Whenever any approval, acceptance, consent, direction or action of
Seller is required pursuant to this Agreement, Purchaser shall send to the
Designated Representative a written notice requesting same, which notice shall:
(i) describe in detail the matter for which such approval, acceptance, consent,
direction or other action of Seller is requested; (ii) be accompanied by a copy
of any contract, agreement or other document to be executed by Seller evidencing
such approval, consent, acceptance, direction or action of Seller; and (iii) be
accompanied by such other documents, written explanations and information as may
be reasonably necessary to explain the request fully and completely. Chase will
communicate Seller's response to any such requests to Purchaser. Whenever any
approval, acceptance, consent, direction or action of Purchaser is required
pursuant to this Agreement, Seller shall send to Purchaser a written notice
requesting same, which notice shall: (i) describe in detail the matter for which
such approval, acceptance, consent, direction or other action of Purchaser is
requested; (ii) be accompanied by a copy of any contract, agreement or other
document to be executed by Purchaser evidencing such approval, consent,
acceptance, direction or action of Purchaser; and (iii) be accompanied by such
other documents, written explanations and information as may be reasonably
necessary to explain the request fully and completely.

     14.18  REIT.  Seller hereby advises Purchaser that Seller is qualified as a
real estate investment trust under the provisions of the Internal Revenue Code
of 1986, as amended, and that, by reason thereof, the maintaining of such status
and the avoiding of any activity which might cause a penalty tax to be applied
is of material concern to Seller. Accordingly, Purchaser agrees to make any
modifications or amendments to this Agreement requested by Seller prior to
Closing that may be necessary for Seller to maintain its status as a real estate
investment trust or in order for it to avoid a penalty tax; provided, however,
that Purchaser shall have no obligation to enter into any such modification or
amendment that would materially alter or affect, in Purchaser's sole judgment,
Purchaser's rights, duties, or obligations under this Agreement. If Purchaser
declines to modify or amend this Agreement for any reason in a manner which
Seller determines, in the good faith exercise of its reasonable business
judgment, is necessary to maintain its status as a real estate investment trust
or avoid a penalty tax, Seller shall have the right to terminate this Agreement
by written notice delivered to Purchaser. In the event Seller exercises such
termination right, neither party shall have any further rights or obligations
hereunder (except with respect to provisions of this Agreement which recite that
they survive termination), the Earnest Money shall be returned to Purchaser and
all other funds and documents deposited in escrow shall be returned to the party
depositing the same.

     14.19  Exculpation.  No present or future officer, director, trust manager,
employee or agent of Seller shall have any personal liability, directly or
indirectly, and recourse shall not be had against any such officer, director,
trust manager, employee, or agent, under or in connection with this Agreement or
any other document or instrument heretofore or hereafter executed in connection
with this Agreement either before or after Closing. Purchaser hereby waives and
releases any and all such personal liability and recourse. The limitations of
liability provided in this Section are in addition to, and not in limitation of,
any limitation on liability provided for elsewhere in this Agreement or
otherwise provided by law or in any other contract, agreement or instrument. No
present or future officer, director, trust manager, employee or agent of
Purchaser shall have any personal liability, directly or indirectly, and
recourse shall not be had against any such officer, director, trust manager,
employee or agent, under or in connection with this Agreement either before or
after Closing. Seller hereby waives and releases any and all such personal
liability and recourse. The limitations of liability provided in this Section
are in addition to, and not in limitation of any limitation on liability
provided for elsewhere in this Agreement or otherwise provided by law or in any
other contract, agreement or instrument.

     14.20  Joint and Several Liability of Seller.  Each entity comprising
Seller shall be jointly and severally liable for all obligations of Seller
hereunder.

                                   ARTICLE 15

                                  ESCROW AGENT

     15.1  Escrow Provisions; Payment at Closing.  If the Closing takes place
under this Agreement, Escrow Agent shall deliver the Earnest Money to Purchaser.

     15.2  Payment on Demand.  Upon receipt of any written certification from
Seller or Purchaser claiming the Earnest Money pursuant to the provisions of
this Agreement, Escrow Agent shall promptly forward a copy thereof to the other
such party (i.e., Purchaser or Seller, whichever did not claim the Earnest Money
pursuant to such notice) and, unless such other party within ten (10) days
thereafter notifies Escrow Agent of any objection to such requested disbursement
of the Earnest Money, Escrow Agent shall disburse the Earnest Money to the party
demanding the same and shall thereupon be released and discharged from any
further duty or obligation hereunder.

     15.3  Exculpation of Escrow Agent.  It is agreed that the duties of Escrow
Agent are herein specifically provided and are purely ministerial in nature, and
that Escrow Agent shall incur no liability whatsoever except for its willful
misconduct or gross negligence, so long as Escrow Agent is acting in good faith.
Seller and Purchaser do each hereby release Escrow Agent from any liability for
any error of judgment or for any act done or omitted to be done by Escrow Agent
in the good faith performance of its duties hereunder and do each hereby
indemnify Escrow Agent against, and agree to hold, save, and defend Escrow Agent
harmless from, any costs, liabilities, and expenses incurred by Escrow Agent in
serving as Escrow Agent hereunder and in faithfully discharging its duties and
obligations hereunder.

     15.4  Stakeholder.  Escrow Agent is acting as a stakeholder only with
respect to the Earnest Money. If there is any dispute as to whether Escrow Agent
is obligated to deliver the Earnest Money or as to whom the Earnest Money is to
be delivered, Escrow Agent may refuse to make any delivery and may continue to
hold the Earnest Money until receipt by Escrow Agent of an authorization in
writing, signed by Seller and Purchaser, directing the disposition of the
Earnest Money, or, in the absence of such written authorization, until final
determination of the rights of the parties in an appropriate judicial
proceeding. If such written authorization is not given, or a proceeding for such
determination is not begun, within sixty (60) days of notice to Escrow Agent of
such dispute, Escrow Agent may bring an appropriate action or proceeding for
leave to deposit the Earnest Money in a court of competent jurisdiction pending
such determination. Escrow Agent shall be reimbursed for all costs and expenses
of such action or proceeding, including, without limitation, reasonable
attorneys' fees and disbursements, by the party determined not to be entitled to
the Earnest Money. Upon making delivery of the Earnest Money in any of the
manners herein provided, Escrow Agent shall have no further liability or
obligation hereunder.

                                   APPENDIX D

       RIGHTS OF DISSENTING SHAREHOLDERS IN THE EVENT OF CERTAIN ACTIONS

     Sec. 25.10. (A) Any shareholder of a domestic real estate investment trust
may dissent from any of the following actions:

          (1) any plan of merger to which the real estate investment trust is a
     party if shareholder approval is required by Section 23.30 of this Act and
     the shareholder holds shares of a class or series that was entitled to vote
     on the plan of merger as a class or otherwise;

          (2) any sale, lease, exchange, or other disposition (not including any
     pledge, mortgage, deed of trust, or trust indenture unless otherwise
     provided in the declaration of trust) of all, or substantially all, of the
     property and assets, with or without good will, of a real estate investment
     trust requiring the special authorization of the shareholders as provided
     by this Act; or

          (3) any plan of exchange pursuant to Section 23.20 of this Act in
     which the shares of the real estate investment trust of the class or series
     held by the shareholder are to be acquired.

     (B) Notwithstanding Subsection (A) of this Section, a shareholder may not
dissent from any plan of merger in which there is a single surviving or new
domestic or foreign corporation, real estate investment trust, partnership, or
other entity, or from any plan of exchange, if:

          (1) the shares held by the shareholder are part of a class or series,
     and on the record date fixed to determine the shareholders entitled to vote
     on the plan of merger or plan of exchange, the shares are:

             (a) listed on a national securities exchange;

             (b) designated as a national market security on an interdealer
        quotation system by the National Association of Securities Dealers,
        Inc., or successor entity; or

             (c) held of record by not less than 2,000 holders; and

          (2) the shareholder is not required by the terms of the plan of merger
     or the plan of exchange to accept any consideration for the shareholder's
     shares other than:

             (a) shares of a domestic or foreign entity that, immediately after
        the effective date of the merger or exchange, will be part of a class or
        series, shares of which are (i) listed, or authorized for listing upon
        official notice of issuance, on a national securities exchange; (ii)
        approved for quotation as a national market security on an interdealer
        quotation system by the National Association of Securities Dealers,
        Inc., or successor entity; or (iii) held of record by not less than
        2,000 holders;

             (b) cash in lieu of fractional shares otherwise entitled to be
        received; or

             (c) any combination of the securities and cash described in this
        Subdivision.

              PROCEDURE FOR DISSENT BY SHAREHOLDERS AS TO ACTIONS

     Sec. 25.20. (A) Any shareholder of any domestic real estate investment
trust who has the right to dissent from any of the actions referred to in
Section 25.10 of this Act may exercise that right to dissent only by complying
with the following procedures:

          (1)(a) With respect to a proposed action that is submitted to a vote
     of shareholders at a meeting, the shareholder shall file with the real
     estate investment trust, before the meeting, a written objection to the
     action. The shareholder's objection must state that the shareholder will
     exercise the shareholder's right to dissent if the action is effective and
     must contain the shareholder's address, to which notice of the action shall
     be delivered or mailed in that event. If the action is effected and the
                                       D-1
   170

     shareholder did not vote in favor of the action, the real estate investment
     trust, in the case of action other than a merger, or the surviving or new
     entity that is liable in the case of a merger to discharge the
     shareholder's right of dissent, shall deliver or mail to the shareholder
     written notice that the action has been effected within 10 days after the
     action is effected. The shareholder may make a written demand on the
     existing, surviving, or new entity for payment of the fair value of the
     shareholder's shares within 10 days from the delivery or mailing of the
     notice. The fair value of the shares shall be the value of the shares on
     the day before the meeting, excluding any appreciation or depreciation in
     anticipation of the proposed action. The demand shall state the number and
     class of the shares owned by the shareholder and the fair value of the
     shares as estimated by the shareholder. A shareholder who fails to make a
     demand within the 10-day period is bound by the action.

          (b) With respect to a proposed action that is approved pursuant to
     Subsection (A) of Section 10.30 of this Act, the real estate investment
     trust, in the case of action other than a merger, and the surviving or new
     entity that is liable in the case of a merger to discharge the
     shareholder's right of dissent, within 10 days after the date the action
     takes effect, shall mail to each shareholder of record as of the date the
     action takes effect notice of the fact and date of the action and that the
     shareholder may exercise the shareholder's right to dissent from the
     action. The notice shall be accompanied by a copy of this Section and any
     articles or documents filed by the real estate investment trust with the
     secretary of state to effect the action. If the shareholder did not consent
     to the taking of the action, the shareholder may make written demand on the
     existing, surviving, or new entity for payment of the fair value of the
     shareholder's shares within 20 days after the mailing of the notice. The
     fair value of the shares shall be the value of the shares on the date the
     written consent authorizing the action was delivered to the real estate
     investment trust pursuant to Subsection (A) of Section 10.30 of this Act,
     excluding any appreciation or depreciation in anticipation of the action.
     The demand shall state the number and class of shares owned by the
     dissenting shareholder and the fair value of the shares as estimated by the
     shareholder. Any shareholder failing to make demand within the 20-day
     period is bound by the action.

          (2) Within 20 days after receipt by the existing, surviving, or new
     entity of a demand for payment made by a dissenting shareholder in
     accordance with Subdivision (1) of this Subsection, the entity shall
     deliver or mail to the shareholder a written notice that shall either set
     out that the entity accepts the amount claimed in the demand and agrees to
     pay that amount within 90 days after the date on which the action was
     effected, and, in the case of shares represented by certificates, on the
     surrender of the certificates duly endorsed, or shall contain an estimate
     by the entity of the fair value of the shares and an offer to pay the
     amount of that estimate within 90 days after the date on which the action
     was effected, on receipt of notice within 60 days after that date from the
     shareholder that the shareholder agrees to accept that amount and, in the
     case of shares represented by certificates, on the surrender of the
     certificates duly endorsed.

          (3) If, within 60 days after the date on which the real estate
     investment trust action was effected, the value of the shares is agreed on
     between the shareholder and the existing, surviving, or new entity, payment
     for the shares shall be made within 90 days after the date on which the
     action was effected and, in the case of shares represented by certificates,
     on surrender of the certificates duly endorsed. On payment of the agreed
     value, the shareholder ceases to have any interest in the shares or in the
     real estate investment trust.

     (B) If, within 60 days after the date on which the action was effected, the
shareholder and the existing, surviving, or new entity do not agree on the value
of the shares, the shareholder or entity, within 60 days after the expiration of
the 60 -- day period, may file a petition in any court of competent jurisdiction
in the county in which the principal office of the domestic real estate
investment trust is located, asking for a finding and determination of the fair
value of the shareholder's shares. On the filing of a petition by the
shareholder, service of a copy of the petition must be made on the entity. The
entity, within 10 days after receiving the service, shall file in the office of
the clerk of the court in which the petition was filed a list containing the
names and addresses of all shareholders of the domestic real estate

                                       D-2
   171

investment trust who have demanded payment for their shares and with whom
agreements as to the value of their shares have not been reached by the entity.
If the petition is filed by the entity, the list described in this Subsection
must be attached to the petition. The clerk of the court shall give notice of
the time and place fixed for the hearing of the petition by registered mail to
the entity and to the shareholders named on the list at the addresses stated in
the list. The court shall approve the forms of notices sent by mail. All
shareholders notified as required by this Subsection and the entity are bound by
the final judgment of the court.

     (C) After the hearing of a petition filed under this Section, the court
shall determine which shareholders have complied with the provisions of this
Section and have become entitled to the valuation of and payment of their
shares. The court shall appoint one or more qualified appraisers to determine
that value. The appraisers may examine any books and records of the real estate
investment trust that relate to the shares the appraisers are charged with the
duty of valuing. The appraisers shall make a determination of the fair value of
the shares after conducting an investigation. The appraisers shall also afford a
reasonable opportunity to allow interested parties to submit to the appraisers
pertinent evidence relating to the value of the shares. The appraisers also have
the power and authority that may be conferred on masters in chancery by the
Texas Rules of Civil Procedure.

     (D) The appraisers shall determine the fair value of the shares of the
shareholders adjudged by the court to be entitled to payment for their shares
and shall file their report of that value in the office of the clerk of the
court. The clerk shall give notice of the filing of the appraisers report to
interested parties. The appraisers report shall be subject to exceptions to be
heard before the court both on the law and the facts. The court shall determine
the fair value of the shares of the shareholders entitled to payment for their
shares and shall order the existing, surviving, or new entity to pay that value,
together with interest on the value of shares to the shareholders entitled to
payment, beginning 91 days after the date on which the applicable action from
which the shareholder elected to dissent was effected to the date of such
judgment. The judgment shall be immediately payable to the holders of
uncertificated shares. The judgment shall be payable to the holders of shares
represented by certificates only on, and simultaneously with, the surrender to
the existing, surviving, or new entity of duly endorsed certificates for those
shares. On payment of the judgment, the dissenting shareholders cease to have
any interest in those shares or in the real estate investment trust. The court
shall allow the appraisers a reasonable fee as court costs, and all court costs
shall be allocated between the parties in the manner that the court determines
to be fair and equitable.

     (E) Shares acquired by the existing, surviving, or new entity, pursuant to
the payment of the agreed value of the shares, to the payment of the agreed
value of the shares, or to payment of the judgment entered for the value of the
shares, as provided in this Section, in the case of a merger, shall be treated
as provided in the plan of merger and, in all other cases, may be held and
disposed of by the real estate investment trust as in the case of other treasury
shares.

     (F) This Section does not apply to a merger if, on the date of the filing
of the articles of merger, the surviving entity is the owner of all the
outstanding shares of the other entities, domestic or foreign, that are parties
to the merger.

     (G) In the absence of fraud in the transaction, the remedy provided by this
Section to a shareholder objecting to any action referred to in Section 25.10 of
this Act is the exclusive remedy for the recovery of the value of the
shareholder's shares or money damages to the shareholder with respect to the
action. If the existing, surviving, or new entity complies with the requirements
of this Section, any shareholder who fails to comply with the requirements of
this Section is not entitled to bring suit for the recovery of the value of the
shareholder's shares or money damages to the shareholder with respect to the
action.

            PROVISIONS AFFECTING REMEDIES OF DISSENTING SHAREHOLDERS

     Sec. 25.30. (A) Any shareholder who has demanded payment for the
shareholder's shares in accordance with Section 25.20 of this Act is not
entitled to vote or exercise any other rights of a shareholder except the right
to receive payment for the shareholder's shares pursuant to the provisions of

                                       D-3
   172

that Section and the right to maintain an appropriate action to obtain relief on
the ground that the action would be or was fraudulent. The respective shares for
which payment has been demanded may not be considered outstanding for the
purposes of any subsequent vote of shareholders.

     (B) On receiving a demand for payment from any dissenting shareholder, the
real estate investment trust shall make an appropriate notation of the demand in
its shareholder records. Within 20 days after demanding payment for shares in
accordance with Section 25.20 of this Act, each holder of certificates
representing those shares shall submit the certificates to the real estate
investment trust for notation on the certificates that such demand has been
made. The failure of holders of certificated shares to submit the certificates
to the real estate investment trust, at the option of the real estate investment
trust, shall terminate the shareholder's rights under Section 25.20 of this Act
unless a court of competent jurisdiction for good and sufficient cause shown
directs otherwise. If uncertificated shares for which payment has been demanded
or shares represented by a certificate on which the real estate investment trust
has made a notation under this Subsection are transferred, any new certificate
issued for those shares shall bear similar notation together with the name of
the original dissenting holder of those shares, and a transferee of those shares
shall acquire by the transfer no rights in the real estate investment trust
other than those which the original dissenting shareholder had after making
demand for payment of the fair value of the shares.

     (C) Any shareholder who has demanded payment for the shareholder's shares
in accordance with Section 25.20 of this Act may withdraw that demand at any
time before payment of those shares has been made or before any petition has
been filed pursuant to Section 25.20 of this Act. The demand may not be
withdrawn after the payment of the shares has been made or after any such
petition has been filed, unless the real estate investment trust consents to the
withdrawal of the demand. The shareholder and all persons claiming under the
shareholder shall be conclusively presumed to have approved and ratified the
action from which the shareholder dissented and shall be bound by the action,
the rights of the shareholder to be paid the fair value of the shareholder's
shares shall cease, and the shareholder's status as a shareholder shall be
restored without prejudice to any proceedings that may have been taken during
the interim, and the shareholder is entitled to receive any dividends or other
distributions made to the shareholders in the interim if:

          (1) the demand is withdrawn as provided in this Subsection;

          (2) pursuant to Subsection (B) of this Section, the demand terminates
     the shareholder's rights under Section 25.20 of this Act;

          (3) no petition asking for a court finding and determination of fair
     value of such shares has been filed within the time provided in Section
     25.20 of this Act; or

          (4) the court determines, after the hearing of a petition filed under
     Section 25.20, that the shareholder is not entitled to the relief provided
     by that Section.
