pay to Seller One Hundred and No/100 Dollars ($100.00) as independent

         3.3 FORM; FAILURE TO DEPOSIT. The Independent Consideration shall be

in which event the parties hereto shall have no further rights or obligations
hereunder, except for rights and obligations which, by their terms, survive the
termination hereof.

applied as a credit to the Purchase Price at Closing, but shall be returned to
Purchaser at Closing. In the event of a termination of this Agreement by either
Seller or Purchaser for any reason, Escrow Agent is authorized to deliver the
Earnest 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 party, unless the other party hereto notifies Escrow Agent that it
disputes the right of the other party to receive the Earnest Money. In such
event, Escrow Agent may interplead the Earnest Money into a court of competent
jurisdiction in the county in which the Earnest





                                                                         Page 6
   7





Money has been deposited. All attorneys' fees and costs and Escrow Agent's
costs and expenses incurred in connection with such 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, then in the proportions
the court determines.

terms and conditions of





                                                                         Page 8

work product or other legally privileged articles of information (collectively,

connection with its due diligence review of the Property; provided, however,
Purchaser shall not be required to make any such deliveries unless and until
Purchaser has received all payments due from Seller, if any, pursuant to
Section 7.5. The Reports shall be delivered to Seller without any
representation or warranty as to the completeness or accuracy of the Reports or
any other matter relating thereto, and Seller shall have no right to rely on

agrees to cause all management agreements to provide for termination without
cause and without penalties payable by Purchaser upon thirty (30) days' prior
written notice. Seller shall deliver at Closing notices of termination of all
Service Contracts required by Purchaser to be terminated. Purchaser must assume
the obligations arising from and after the Closing Date under those Service
Contracts that Purchaser has agreed to assume.

         4.6 PROPRIETARY INFORMATION; CONFIDENTIALITY. Purchaser acknowledges
that 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 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





                                                                         Page 9
   10





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.

         4.8 PURCHASER'S RESPONSIBILITIES. In conducting any inspections,
investigations or tests of the Property and/or Property Information after the
Effective Date, Purchaser and its agents and representatives shall: (i) not
unreasonably disturb the tenants or interfere with their use of the Property
pursuant to or in breach of the terms of their respective Leases; (ii) not
unreasonably interfere with the operation and maintenance of the Property;
(iii) not damage any part of the Property or any personal property owned or
held by any tenant or any third party; (iv) not injure or otherwise cause
bodily harm to Seller, Asset Manager, or their respective agents, guests,
invitees, contractors and employees or any tenants or their guests or invitees;
(v) comply with all applicable laws; (vi) promptly pay when due the costs of
all tests, investigations, and examinations done with regard to the Property;
(vii) not 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 directly or indirectly from any such inspection or tests; and (ix)
not reveal or disclose prior to Closing any information obtained during
Purchaser's inspection activities with respect to the Property prior to the
Effective Date concerning the Property and the Property Information to anyone
other than the Permitted 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.




                                                                        Page 10
   11






                          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






                                                                        Page 11

obligations hereunder except for those obligations which by their terms survive
termination of this Agreement.


                    ARTICLE 6 - OPERATIONS AND RISK OF LOSS


         6.1  ONGOING  OPERATIONS. From the Effective Date through Closing,

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




                                                                        Page 12
   13





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 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.




                                                                        Page 13

          ARTICLE 7 - SHAREHOLDER OBLIGATIONS; OTHER SELLER COVENANTS

         7.1 SHAREHOLDER APPROVAL. Purchaser acknowledges that the transactions
contemplated by this Agreement are subject to the approval of the holders of a
two-thirds majority of the outstanding common shares of AIP ("Shareholder
Approval"). AIP agrees to use good faith and make commercially reasonable
efforts to obtain such Shareholder Approval as soon as practicable. On the
Effective Date, AIP shall deliver to Purchaser voting agreements from the
institutional shareholder designated members of AIP's Board of Trust Managers
who are eligible to vote and support the approval of the transaction
contemplated herein who hold shares and their respective institutional
affiliates which are shareholders of AIP, pursuant to which the signatories to
such voting agreements have agreed to vote in favor of the transactions
contemplated by this Agreement, subject to rights parallel to Seller's rights
hereunder with respect to a Superior Proposal (defined below).

         7.2 PROXY STATEMENT. In furtherance, and not in limitation of the
foregoing, as soon as practicable after the execution of this Agreement using
good faith and commercially reasonable efforts, Seller shall finalize and file
with the United States Securities And Exchange Commission (the "SEC") a
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 and to cause the proxy statement to be mailed to AIP's
shareholders as promptly 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 "Manhattan Towers Project") for a gross purchase price of at
least $48,000,000.00. Seller shall use good faith and commercially reasonable
efforts to cause the sale of the Manhattan Towers Project to occur on such
terms and prior to or contemporaneously with Closing.

         7.4 DDR CLOSING. In connection with the transactions contemplated by
the Agreement, AIP intends to cause Developers Diversified Realty Corporation
("DDR") to acquire AIP, generally in accordance with the term sheet to which
DDR and AIP are parties. Seller shall use good faith and commercially
reasonable efforts to cause the merger with a subsidiary of DDR (or such other
structure as agreed upon by DDR and AIP which results in DDR owning AIP) to
occur 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
Outside Closing Date, or (B) cause the closing of the sale of the Manhattan
Towers Project to occur prior to or contemporaneously with Closing, or (C)
cause the closing of DDR's acquisition of the outstanding shares of AIP to
occur contemporaneously with Closing, and as a result of (A) or (B) or (C),
Seller elects or is required to terminate this Agreement; or (ii) following the
Effective Date, Seller receives a Superior Acquisition Proposal and as a result
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






                                                                        Page 14
   15





Purchaser a break up fee of $3,000,000.00, and will reimburse Purchaser for the
actual and verifiable out-of-pocket costs, including legal fees actually
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 of any such termination of the merger agreement with DDR, or Seller shall
be 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.

         7.6 NON-SOLICITATION. After the Effective Date and prior to the
termination of this Agreement in accordance with its terms, Seller agrees that:

                  (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 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






                                                                        Page 15
   16





(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.


                           ARTICLE 8 - EXISTING LOANS

Subject to Section 9.2.4, Purchaser shall either (i) acquire the Properties
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
been approved by the applicable lender. Purchaser and Seller shall cooperate in
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
assumption fees and charges; (iii) obtain favorable terms of assumption for any
loans contemplated to be assumed; and (iv) obtain estoppel statements from
applicable lenders.


                              ARTICLE 9 - CLOSING

party elects to close (or to permit any such earlier termination deadline to
pass), notwithstanding the non-satisfaction of such condition, said party shall
be deemed to have waived said condition, and there shall be no liability on the

Specifically, the following shall apply to such prorations:

                  10.1.1 TAXES. If Taxes for the year of Closing are not known
or cannot be reasonably estimated, Taxes shall be prorated based on Taxes for
the year prior to Closing. Any additional Taxes relating to the year of Closing
arising out of a change in ownership shall be assumed by Purchaser effective as
of Closing and paid by Purchaser when due and payable, and Purchaser shall
indemnify Seller from and against any and all such Taxes, which indemnification
obligation shall survive the Closing.

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

                  (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)

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

         10.3 CAPITAL EXPENDITURES. To the extent Seller did not fund all

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 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


                                                                        Page 21
   22


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

attorneys' fees and litigation costs) arising as a result of such claims and
shall survive the Closing.

this Agreement and recover the Earnest Money as liquidated damages and not as

amount of such damages to be certain. Notwithstanding anything in this Section
12.1 to the contrary, in the event of Purchaser's default or a termination of

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

OTHER LIABILITY ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE PROPERTY,

Agreement by 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 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

requires owners of nonresidential property who know or have reasonable cause to
believe that any release of hazardous substance has come to be located on or
beneath real property to provide written notice of that condition to a buyer of
such 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 described in the environmental reports and documents which have been
received and reviewed by Purchaser. By its execution of this Agreement,
Purchaser acknowledges its receipt of the foregoing notice given pursuant to
Section 25359.7 of the California Health and Safety Code.



                                                                         Page 26

                  (c) Purchaser acknowledges that "Natural Hazards" described

determine whether any such Natural Hazards affect any of the Projects.
Purchaser further represents and warrants that Purchaser has independently
evaluated and investigated whether any or all of such Natural Hazards affect
the one or more of the Projects. Based on the foregoing, Purchaser knowingly

PURCHASER'S INITIALS
                    ---------------

         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
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:
                              ----------------

         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,"



                                                                         Page 28

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.

         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.


                                                                         Page 29

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

         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

writing and shall be served on the parties at the addresses set forth in
Section 1.3. Any such notices shall, unless otherwise provided herein, be given

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.


                                                                         Page 30

         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

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 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


                                                                         Page 31
   32

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


                                                                         Page 32

   33

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.
