                           PURCHASE AND SALE AGREEMENT


         THIS PURCHASE AND SALE AGREEMENT (this "AGREEMENT") is made and entered
into as of the 29th day of April, 2002 (the "EFFECTIVE DATE"), by and between
(A) THE MILLS LIMITED PARTNERSHIP, a Delaware limited partnership, as purchaser
("PURCHASER") on its own behalf and on behalf of the Mills Interest Holders
(defined below), and (B) SIMON PROPERTY GROUP, L.P., a Delaware limited
partnership, M.S. MANAGEMENT ASSOCIATES, INC., a Delaware corporation, SIMON
PROPERTY GROUP (TEXAS), L.P., a Texas limited partnership, and SPG REALTY
CONSULTANTS, L.P., a Texas limited partnership, collectively as seller
("SELLER").

                                R E C I T A L S:
                                ---------------

        A. Purchaser and Seller are parties to two separate letter agreements
dated August 16, 1995 and November 30, 1995 (collectively, the "MASTER
AGREEMENT"), pursuant to which Purchaser and Seller developed and currently own
interests, directly or indirectly, in the following shopping centers:

        (i)      Arizona Mills, Tempe, Arizona ("ARIZONA MILLS");

        (ii)     Arundel Mills, Hanover, Maryland ("ARUNDEL MILLS");

        (iii)    Concord Mills, Concord, North Carolina ("CONCORD MILLS");

        (iv)     Grapevine Mills, Grapevine, Texas ("GRAPEVINE MILLS"); and

        (v)      Ontario Mills, Ontario, California ("ONTARIO MILLS").

Arizona Mills, Arundel Mills, Concord Mills, Grapevine Mills and Ontario Mills
are sometimes referred to individually as a "PROJECT" or collectively as the
"PROJECTS." In addition, pursuant to the Master Agreement, Purchaser and its
affiliates (collectively, "MILLS") and Seller and its affiliates (collectively,
"SIMON") have jointly pursued certain additional developments and other
opportunities (the "POTENTIAL DEVELOPMENTS"), including without limitation, a
potential project in San Francisco, California known as "CANDLESTICK MILLS".

        B. Separate and apart from the Master Agreement, Simon owns a
controlling interest and Mills owns a non-controlling interest in (i) Houston
Development I Limited Partnership, a Texas limited partnership, and (ii) its
general partner, Houston Development LLC, a Texas limited liability company
(collectively, the "INTERFIN DEVELOPMENT COMPANIES"). Houston Development I,
Limited Partnership owns a parcel of land that is located in Harris County,
Texas and is known by the parties and referred to herein as the
"HOUSTON/INTERFIN SITE." The Houston/Interfin Site is not included within the
terms "PROJECT" or "POTENTIAL DEVELOPMENT" hereunder.

        C. The ownership interests of Mills and Simon in the Projects consist
of the interests identified on EXHIBIT A attached hereto and by this reference
made a part hereof in certain



<PAGE>


limited partnerships (collectively, the "PARTNERSHIPS"), limited liability
companies (collectively, the "LLCS") and corporations (collectively, the
"CORPORATIONS") (the Partnerships, the LLCs and the Corporations are sometimes
referred to collectively as the "VENTURE COMPANIES"). EXHIBIT A identifies the
Project to which each Venture Company relates, and the role of the Venture
Company in connection therewith. The Venture Companies for a given Project are
sometimes referred to herein collectively by the name of the Project, as for
example the "ARIZONA MILLS VENTURE COMPANY." Each entity (including the entities
comprising Seller) that owns a direct interest in a Venture Company and which is
directly or indirectly owned or controlled by Seller or Simon, is referred to
herein as a "SIMON INTEREST HOLDER." Each entity that owns a direct interest in
a Venture Company and which is directly or indirectly owned or controlled by
Purchaser or by Mills is referred to herein as a "MILLS INTEREST HOLDER." The
term "VENTURE COMPANIES" does not include the Interfin Development Companies.

        D. The organizational documents for the Venture Companies are identified
on EXHIBIT B attached hereto and by this reference made a part hereof (the
"ORGANIZATIONAL DOCUMENTS"). In connection with the management and operation of
the Venture Companies, the Mills Interest Holders and the Simon Interest Holders
are parties to the applicable limited liability company operating agreements
("OPERATING AGREEMENTS"), limited partnership agreements (collectively, the
"PARTNERSHIP AGREEMENTS") or shareholder agreements (collectively the
"SHAREHOLDER AGREEMENTS") identified on EXHIBIT B.

        E. Attached hereto as EXHIBIT C is a chart depicting the ownership
structure for each of the Projects and the ownership interests of Mills and
Simon in each of the Venture Companies.

        F. The right, title and interest of each Simon Interest Holder in a
Venture Company is referred to herein as a "SIMON OWNERSHIP INTEREST." The term
"SIMON OWNERSHIP INTEREST" specifically excludes any ownership interests in the
Interfin Development Companies. The Simon Ownership Interests in the Venture
Companies for a given Project are sometimes referred to herein collectively by
the name of the Project, as for example the "ARIZONA MILLS SIMON OWNERSHIP
INTERESTS." The rights and interests of Seller in and to the Master Agreement
are referred to herein collectively as the "SIMON MASTER AGREEMENT RIGHTS."

        G. Purchaser desires to buy all of the Simon Ownership Interests and the
Simon Master Agreement Rights from Seller and the Simon Interest Holders, and
Seller desires to sell (or cause the Simon Interest Holders to sell) all of the
Simon Ownership Interests, terminate the Master Agreement and extinguish the
Simon Master Agreement Rights, on the terms set forth in this Agreement.

        H. Mills and Simon have agreed to modify the organizational documents of
the Interfin Development Companies at the Closing hereunder, as set forth below.

        I. Pursuant to a letter agreement dated March 27, 2002 between Mills and
Simon (the "G-2 LETTER Agreement"), on March 29, 2002 (the "G-2 CLOSING DATE"),
Mills purchased a portion of Arundel Mills, known as the "G-2 BLOCK," and
compensated Simon by: (i) paying 20% of Simon's share of the purchase price to
Simon in cash on March 29, 2002, and


                                       2
<PAGE>


(ii) delivering to Simon a promissory note (the "G-2 NOTE") for the balance of
the purchase price, a copy of which is attached hereto as EXHIBIT D.

        NOW, THEREFORE, in consideration of the mutual agreements set forth in
this Agreement and for other good and valuable consideration, the receipt and
sufficiency of which are hereby acknowledged, Seller and Purchaser hereby agree
as follows:

                                   ARTICLE I.

                 PURCHASE PRICE AND OTHER ECONOMIC CONSIDERATION

SECTION 3.01  PURCHASE PRICE.  The total consideration to be paid by Purchaser
for the Simon Ownership Interests is One Hundred Seventy-Five Million Dollars
($175,000,000) (the "PURCHASE PRICE"), allocated among the respective Projects
as set forth on EXHIBIT E attached hereto and by this reference made a part
hereof. The portion of the Purchase Price that is allocated to the Simon
Ownership Interests relative to a particular Project is referred to herein as
the "PROJECT PURCHASE PRICE" for such Project.

SECTION 3.02  PAYMENT OF PURCHASE PRICE.  At each "CLOSING" (as such term is
defined in Section 6.01), Purchaser shall pay to Seller an amount equal to the
aggregate of the Project Purchase Prices for the Projects with respect to which
the Closing is occurring (as such amount may be adjusted pursuant to Section
6.03 hereof), such amount to be paid by Purchaser by federal funds wire
transferred to Seller or Seller's designee pursuant to wire instructions which
Seller agrees to furnish to Purchaser not less than two (2) business days prior
to the Closing Date (as such term is defined in Section 6.01), subject, however,
to such adjustments as are required by this Agreement (such amount, as adjusted
for each Closing, being referred to herein as the "CASH BALANCE").

                                  ARTICLE IV.

                         REPRESENTATIONS AND WARRANTIES

SECTION 4.01  SELLER'S REPRESENTATIONS AND WARRANTIES.  Seller represents and
warrants to Purchaser that as of the date of this Agreement:

  (a)    Seller and each of the other Simon Interest Holders is a limited
         liability company, limited partnership or corporation, as applicable,
         duly organized, validly existing and in good standing under the laws
         of the state in which said entity was formed. Seller has the full
         power and lawful authority under its respective organizational
         documents to execute, deliver and perform this Agreement and all
         documents which are contemplated to be delivered at Closing pursuant
         to this Agreement, and each of the Simon Interest Holders has the full
         power and lawful authority to execute, deliver and perform all
         instruments and agreements contemplated by this Agreement to be
         delivered by said entity. All actions necessary to confer such power
         and authority upon the persons executing this Agreement (and all
         documents which are contemplated by this Agreement to be executed by
         the respective Simon Interest Holders) have been taken. Seller's
         execution, delivery and performance of this Agreement, and each Simon
         Interest Holder's execution, delivery and performance of any of the
         documents contemplated to be executed and delivered at closing
         pursuant to this Agreement, will not result in any violation of, or
         default under, or require any notice or consent under, any of the
         organizational documents of said entity.


                                       4
<PAGE>


  (b)    All of the Simon Ownership Interests are owned by Seller or, as the
         case may be, the applicable Simon Interest Holder, free and clear of
         any and all security agreements, financing statements, liens
         (including federal, state or local tax liens and any liens arising
         pursuant to state bulk sales or bulk transfer laws), encumbrances,
         security interests or other claims of any kind (collectively,
         "LIENS"). The Simon Ownership Interests are not subject to any option,
         right of first refusal, purchase agreement, put, call or other right
         to purchase (collectively, "PRE-EMPTIVE RIGHTS"), other than (i) this
         Agreement (ii) the Pre-Emptive Rights of third parties expressly set
         forth in the Venture Companies' Organizational Documents. The
         applicable Simon Ownership Interests shall be transferred to Purchaser
         upon the consummation of each Closing free and clear of all Liens and
         Pre-Emptive Rights.

  (c)    LITIGATION. No litigation or proceedings are pending, or to the best of
         Seller's knowledge, threatened against Seller or any of the Simon
         Interest Holders which have or will have a material adverse effect on
         the ability of Seller or any Simon Interest Holder to perform its
         obligations (or to enter into the agreements contemplated to be entered
         into by it) under this Agreement.

  (d)    FIRPTA.  Neither Seller nor any of the Simon Interest Holders is a
         foreign entity for purposes of Section 1445 of the Internal Revenue
         Code of 1986, as amended.

  (e)    ERISA. None of the Simon Ownership Interests constitute "Plan Assets"
         of any employee benefit plan, subject to the Employee Retirement Income
         Security Act of 1974 ("ERISA") within the meaning of 29 CFR
         Section 2510.3-101.

         For purposes of this Agreement, any representations and warranties made
to the "best of Seller's knowledge" (or terms of similar import) shall be deemed
to mean the actual knowledge of David Simon, Randolph Foxworthy and James
Barkley, after reasonable inquiry within Seller's organization, but without
inquiry of unaffiliated third parties.

SECTION 4.02  PURCHASER'S REPRESENTATIONS AND WARRANTIES.  Purchaser represents
and warrants to Seller that as of the date of this Agreement:

  (a)    Purchaser is a Delaware limited partnership, duly organized and validly
         existing and in good standing under the laws of the State of Delaware,
         and has full power and lawful authority under Purchaser's
         organizational documents to enter into and carry out the terms and
         provisions of this Agreement and to execute and deliver all documents
         which are contemplated by this Agreement. All actions necessary to
         confer such power and authority upon the persons executing this
         Agreement (and all documents which are contemplated by this Agreement
         to be executed by Purchaser) have been taken. Purchaser's execution,
         delivery and performance of this Agreement, and the documents
         contemplated to be executed and delivered at closing pursuant to this
         Agreement, will not result in any violation of, or default under, or
         require any notice or consent under, any of the organizational
         documents of Purchaser.


                                       5
<PAGE>


  (b)    ERISA. Purchaser shall not utilize "Plan Assets," within the meaning of
         ERISA, to acquire the Simon Ownership Interests or the Simon Master
         Agreement Rights.

SECTION 4.03  PRE-CLOSING DISCLOSURE.  As of each Closing, Purchaser and Seller
shall each be deemed to remake and restate the representations set forth in this
Article 4, except as may be disclosed by either party to the other in writing on
or before said Closing (any such disclosure being referred to herein as a
"PRE-CLOSING DISCLOSURE"), and except for any representation or warranties
relating solely to Projects with respect to which Closing has previously
occurred.

SECTION 4.04  SURVIVAL.  The representations and warranties set forth in
Sections 4.01 and 4.02, subject to modifications thereto pursuant to
Section 4.03, shall survive each Closing forever.

                                   ARTICLE V.

                              CONDITIONS PRECEDENT

SECTION 5.01  PURCHASER'S CONDITIONS PRECEDENT.  Purchaser's obligations under
this Agreement are subject to the satisfaction of the following conditions, the
failure of any of which as of the then-applicable "Approval Deadline" (as such
term is defined in Section 5.05(i)), shall have the consequences set forth in
Section 5.05:

  (a)    REPRESENTATIONS.  Each and every representation and warranty set forth
         in Section 4.01 shall be materially true and correct as of Closing, as
         modified by any Pre-Closing Disclosures. If a representation of Seller
         is limited to Seller's knowledge, and the factual matter represented
         to (as modified by any Pre-Closing Disclosures) is not true and
         correct in all material respects, then there shall be a failure of
         this condition precedent. Notwithstanding the foregoing, if Seller
         makes any material Pre-Closing Disclosure (i.e., any Pre-Closing
         Disclosure which would render the representations and warranties of
         Seller set forth in this Agreement false or misleading in any material
         respect) to Purchaser, then Purchaser shall have the right to
         terminate this Agreement, with the consequences described above in
         this Section 5.01, by delivering written notice thereof to Seller on
         or before (i) the Closing or (ii) the fifth (5th) business day after
         Purchaser receives written notice of such Pre-Closing Disclosure (and
         if such day is after the scheduled Closing Date, Closing shall be
         extended accordingly). If Purchaser does not terminate this Agreement
         pursuant to its rights under this Section 5.01(a), then such
         representations and warranties shall be deemed modified to conform
         them to the Pre-Closing Disclosures; provided, however, that if a
         Pre-Closing Disclosure shall be caused by or reflect a fraudulent
         misrepresentation, breach of representation or breach of Seller's
         obligations under this Agreement, then in addition to its right to
         terminate this Agreement, Purchaser shall be entitled to the remedies
         available to it under Section 9.01.

  (b)    LENDER CONSENTS/APPROVALS.  With respect to each Project, all "Project
         Lenders" (as such term is defined below) who, by the terms of the
         applicable loan documents, have the right to approve or consent to the
         transactions contemplated by this Agreement (or the right to declare a
         default if such approval or consent is not obtained), shall have
         furnished such approvals and consents, including (if required) rating
         agency approvals and/or so-called


                                       6
<PAGE>


         "no downgrade letters" (collectively, the "LENDER CONSENTS"). Attached
         hereto as EXHIBIT G is a schedule identifying (i) the mortgage debt
         applicable to each Project (each such debt obligation being referred
         to herein as a "MORTGAGE LOAN"), the original principal amount of each
         Mortgage Loan, the holders thereof and any servicers and agents with
         respect thereto (collectively, the "PROJECT LENDERS") and (ii) any
         instruments entered into by Simon (excluding the Venture Companies
         themselves) in favor of the Project Lenders, which impose any recourse
         obligations (including indemnities, guaranties or other pecuniary
         obligations) on Simon that would survive the Closing hereunder in the
         absence of the releases contemplated hereunder (the "SIMON LOAN
         GUARANTIES").

  (c)    KAN AM CONSENTS.  If and to the extent that Kan Am Realty and its
         affiliates (collectively, "KAN AM") have the right to approve or
         consent to the transfer of the Simon Ownership Interests to Mills
         pursuant to the applicable Organizational Documents, Kan Am shall have
         consented to such transfer in writing (such consents are referred to
         herein as the "KAN AM CONSENTS").

  (d)    HOUSTON/INTERFIN SITE.  Simon shall have executed and delivered, at
         Closing, the documents in the form attached hereto as EXHIBIT H
         (collectively, the "HOUSTON/INTERFIN MODIFICATION DOCUMENTS") (i)
         amending or supplementing the venture agreements between Simon and
         Mills with respect to the Houston/Interfin Site, and (ii) modifying
         the restrictions under an existing agreement relative to the sale or
         lease of property at a shopping center owned by Mills and known as
         "KATY MILLS," all as set forth more particularly in EXHIBIT H. In
         addition, Simon shall have caused the entity that owns the
         Houston/Interfin Site to execute and deliver to Mills a restrictive
         covenant restricting certain uses of the Houston/Interfin Site, (the
         "HOUSTON/INTERFIN RESTRICTIVE COVENANT"), in the form of EXHIBIT H-1
         attached hereto, which shall be recorded against the land comprising
         the Houston/Interfin Site at Closing.

  (e)    UCC SEARCHES. Purchaser (at its sole cost and expense) shall have
         obtained UCC and such other searches as Purchaser may reasonably
         require, dated as close as possible to the Closing, confirming that the
         Simon Ownership Interests are owned by the applicable Simon Interest
         Holder free and clear of all Liens.

  (f)    NO DEFAULT.  Seller shall not be in default of any of its material
         obligations in any material respect.

SECTION 5.02  SELLER'S CONDITIONS PRECEDENT.  The obligations of Seller under
this Agreement are contingent upon any one or more of the following, the failure
of any of which as of the then-applicable "Approval Deadline" (as such term is
defined in Section 5.05(i) shall have the consequences set forth in
Section 5.05.

  (a)    REPRESENTATIONS.  Each and every representation and warranty set forth
         in Section 4.02 shall be true and correct in all material respects as
         of Closing.

                                       7
<PAGE>


  (b)    SIMON LOAN GUARANTIES. With respect to each of the Simon Loan
         Guaranties, the applicable Project Lender shall have terminated the
         Simon Loan Guaranty or released Simon from all further obligations and
         liabilities arising thereunder (said releases are referred to herein
         collectively as the "SIMON LOAN RELEASES").

  (c)    SIMON KAN AM GUARANTIES. EXHIBIT I identifies certain guaranties and
         indemnities made by Seller and its affiliates in favor of Kan Am
         (collectively, the "SIMON KAN AM GUARANTIES") in connection with the
         Venture Companies. With respect to each of the Simon Kan Am Guaranties,
         the applicable Kan Am entities (as identified on EXHIBIT I) shall have
         terminated the Simon Kan Am Guaranty or released Simon from all further
         obligations and liabilities arising thereunder (said releases are
         referred to herein collectively as the "SIMON KAN AM RELEASES").

  (d)    NO DEFAULT.  Purchaser shall not be in default of any of its material
         obligations in any material respect.

SECTION 5.03  MUTUAL COOPERATION.  Seller and Purchaser will cooperate
diligently and in good faith to satisfy the foregoing conditions precedent,
including using commercially reasonable efforts to obtain the Lender Consents,
the Kan Am Consents, the Simon Loan Releases, the Simon Kan Am Releases and the
other consents and approvals set forth in Sections 5.01 and 5.02, as soon as
possible after the Effective Date hereof and, in any event, on or before the
Approval Deadline (defined below); PROVIDED, however, that Purchaser shall not
be required to (i) pay any fees to obtain the Lender Consents or the Simon Loan
Releases, other than (x) fees expressly required to be paid by the terms of the
existing documents evidencing or securing the Mortgage Loans (collectively, the
"LOAN DOCUMENTS"), which shall be shared equally by Seller and Purchaser as
provided in Section 6.04 below and (y) out-of-pocket expenses required to be
reimbursed to Project Lenders (including rating agencies) for counsel fees and
the like, which also shall be shared equally by Purchaser and Seller as provided
in Section 6.04 below, (ii) accept any modification of any Loan Document that
may be requested or required by any Project Lender as a condition to furnishing
a Lender Consent or a Simon Loan Release, or (iii) pay any fees to obtain the
Kan Am Consents or the Kan Am Releases (other than out-of-pocket expenses
required to be reimbursed to Kan Am for counsel fees and the like, which also
shall be shared equally by Purchaser and Seller as provided in Section 6.04
below) or accept any modification of any Organizational Documents that may be
requested or required by Kan Am as a condition of furnishing the Kan Am Consents
or the Simon Kan Am Releases. Notwithstanding the foregoing, if Purchaser (in
its sole and absolute discretion) elects to refinance any Mortgage Loan at
Closing, Seller shall cooperate in advance with such refinancing if it is
structured so that Simon will not be required to furnish any guaranties or
indemnities in connection therewith, and in that case (subject to the closing of
said refinancing) the requirement of obtaining a Simon Loan Release with respect
to the Mortgage Loan that is being refinanced shall be deemed satisfied.

SECTION 5.04  SIMULTANEOUS CLOSINGS.  Except as expressly provided below in this
Section 5.04, (i) it shall be an additional condition precedent to the Closing
hereunder that the Closing shall occur simultaneously with respect to all
Projects, and (ii) neither Seller nor Purchaser shall have


                                       8
<PAGE>

any right or obligation to proceed to Closing with respect to any Project unless
the Closings for all other Projects have already occurred or are occurring
simultaneously.

   (a)    POSTPONEMENT OF ARIZONA MILLS CLOSING FOR TAUBMAN PURCHASE RIGHTS.
          Purchaser and Seller acknowledge that Taubman Realty Group, L.P.
          ("TRG") has the right to purchase one-half of the Arizona Mills Simon
          Ownership Interests pursuant to certain rights (collectively, the "PRO
          RATA PURCHASE RIGHTS") set forth in Section 11.3 of the Amended and
          Restated Limited Liability Company Agreement of Arizona Mills, L.L.C.,
          Section 10.3 of the Limited Liability Company Agreement of Arizona
          Mills II, L.L.C., and Section 10.3 of the Amended and Restated Limited
          Liability Company Agreement of MTS Services of Tempe, L.L.C
          (collectively, the "PRO-RATA PURCHASE PROVISIONS"). On March 27, 2002,
          Seller notified TRG of TRG's right to exercise the Pro Rata Purchase
          Rights with respect to the Arizona Mills Simon Ownership Interests. If
          TRG exercises the Pro Rata Purchase Rights in accordance with the
          Pro-Rata Purchase Provisions, then, provided all other conditions
          precedent to the Closing have been satisfied or waived, (i) Purchaser
          shall be obligated to purchase (and at Closing shall purchase) only
          one-half of the Arizona Mills Simon Ownership Interests, and the other
          one-half of the Arizona Mills Simon Ownership Interests will be
          transferred or assigned to TRG or its designee in accordance with the
          Pro-Rata Purchase Provisions, (ii) the Purchase Price for the Arizona
          Mills Ownership Interests purchased by Purchaser shall be reduced
          proportionately, and (iii) if necessary, in order to permit the
          simultaneous closing with TRG under the Pro-Rata Purchase Provisions
          and the Closing of Purchaser's acquisition of one-half of the Arizona
          Mills Simon Ownership Interests under this Agreement, the Closing Date
          with respect to Arizona Mills shall be the later of (x) the initial
          Closing Date with respect to the other Projects hereunder, or (y) the
          date provided for the closing under the Pro-Rata Purchase Provisions
          (i.e., sixty (60) days after the date TRG exercises the Pro-Rata
          Purchase Rights). Specifically, if TRG exercises its Pro-Rata Purchase
          Rights, then the Project Purchase Price payable by Purchaser for the
          Arizona Mills Simon Ownership Interests (subject to adjustment as
          contemplated under Section 6.03) will be $14,022,500 and the aggregate
          Purchase Price will be reduced accordingly.

                  The postponement of the Arizona Mills Closing as provided in
          this Section 5.04(a) shall not affect the Closing Date of the other
          Projects.

  (b)     POSTPONEMENT OF CLOSING OF A SINGLE PROJECT.  In addition to the
          possible postponement of Closing with respect to Arizona Mills as
          provided in Section 5.04(a) above, the Closing with respect to not
          more than one (1) Project (the "DELAYED PROJECT") may be postponed to
          a date after the Closing with respect to the other Projects (excluding
          the Arizona Mills Closing, if postponed as provided above) (the
          "INITIAL CLOSING") as provided in this Section 5.04(b) if the
          conditions precedent to the Closing with respect to the Delayed
          Project are not satisfied or waived on or before the Approval
          Deadline. In such event, (i) the Approval Deadline will be extended as
          provided in Section 5.05 with respect to the Delayed Project only, and
          (ii) the Initial Closing will occur on the scheduled Closing Date with
          respect to all Projects other than (x) the Delayed Project and (y) if
          and only if applicable under Section 5.04(a), Arizona Mills, and (iii)
          the Closing with respect to the


                                       9
<PAGE>


         Delayed Project will occur on the date that is the first to occur of
         the Outside Closing Date (defined below) or five (5) business days
         after the conditions precedent to the closing of the Delayed Project
         are satisfied or waived.

                  Unless the conditions precedent to the Closing of four (4) or
         more Projects are satisfied on or before the Approval Deadline, then
         the Approval Deadline shall be extended as provided in Section 5.05,
         but not beyond the Outside Approval Deadline (defined below), and the
         Closing with respect to all of the Projects will be likewise postponed.

                  Arizona Mills may be the Delayed Project, if there are
         conditions precedent to the Arizona Mills Closing (other than the
         postponement pursuant to Section 5.04(a) above) that are not satisfied
         or waived by the Approval Deadline. The conditions precedent to the
         Arizona Mills Closing shall be deemed to be satisfied for purposes of
         this Section 5.04(b) and Section 5.05(a) below, if the Arizona Mills
         Closing is postponed pursuant to Section 5.04(a) above but all other
         conditions precedent to the Arizona Mills Closing are satisfied.

SECTION 5.05  APPROVAL DEADLINE; TERMINATION.  The term "APPROVAL DEADLINE"
shall mean June 1, 2002, as the same may be extended pursuant to this Section
5.05. If the conditions precedent to Closing of any of the Projects (other than
the postponement of Closing with respect to Arizona Mills pursuant to Section
5.04(a) above) are not satisfied or waived on or before the Approval Deadline
(as theretofore extended), then Purchaser and Seller shall each have the right
to extend the Approval Deadline for two (2) successive one-month periods (i.e.
first to July 1, 2002 and then to August 1, 2002), by furnishing notice thereof
to the other party on or before the then applicable Approval Deadline, PROVIDED
however that said notice shall only be effective if the condition or conditions
in question are not satisfied or waived on or before the Approval Deadline that
was in effect prior to said proposed extension and (y) neither party shall have
the right to extend the Approval Deadline beyond August 1, 2002 (the "OUTSIDE
APPROVAL DEADLINE"); and PROVIDED FURTHER, however, that (x) if there is just
one (1) Delayed Project, as provided in Section 5.04(b) above, then the
extension of the Approval Deadline shall apply only to such Delayed Project and
the parties will proceed to the Closing with respect to the other Projects as if
the Approval Deadline had not been extended, and (y) otherwise, the extension of
the Approval Deadline shall apply to all Projects and the Closing with respect
to all Projects will be likewise postponed.

  (a)    TERMINATION WITH RESPECT TO ALL PROJECTS. Unless the conditions
         precedent to the Closing of four (4) or more Projects are satisfied on
         or before the Approval Deadline (as the same may be extended), then
         upon written notice from either party to the other, this Agreement
         shall be terminated with respect to all of the Projects.

  (b)    TERMINATION WITH RESPECT TO DELAYED PROJECT ONLY. If the conditions
         precedent to the Closing of a single Delayed Project (only) are not
         satisfied or waived on or before the Approval Deadline (as the same may
         be extended), then upon written notice from either party to the other,
         this Agreement shall be terminated with respect to the Delayed Project
         only.


                                       10
<PAGE>


SECTION 5.06  WAIVERS OF CONDITIONS PRECEDENT.  Any condition precedent to the
Closing hereunder may be waived by the party (or in the case of the joint
conditions contained in Section 5.03, all parties) for whose benefit such
condition exists (such election being at the sole and absolute discretion of
such party), with any such condition being deemed waived in the event that the
Closing occurs and provided further that in such event the other party shall
have no liability to the waiving party related to the matter or matters so
waived.

SECTION 5.07  FAILURE OF CONDITIONS PRECEDENT NOT A DEFAULT.  Subject to the
provisions of Article IX, the failure of any of the conditions precedent to
Closing set forth in this Article V shall not, solely by virtue of such failure,
constitute a default by either Purchaser or Seller. Subject to the provisions of
Article IX, in the event that a condition precedent to either or both of
Seller's or Purchaser's obligation to close the transaction has not been
satisfied as of Closing (as the same may be adjourned pursuant to Section 5.05
or otherwise provided in this Agreement), the party whose condition has not been
satisfied may terminate this Agreement by written notice to the other party as
provided in Sections 5.05, as applicable.

                                   ARTICLE VI.

                                     CLOSING

SECTION 6.01  CLOSING DATE.  The "CLOSING" of the transactions contemplated by
this Agreement (that is the payment of the Purchase Price, the transfer of the
Simon Ownership Interests, and the satisfaction of all other terms and
conditions of this Agreement) shall occur on the date (the "CLOSING DATE") which
is the first business day after the Approval Deadline (i.e., June 3, 2002 if the
Approval Deadline is not extended; July 2, 2002 if the Approval Deadline is
extended for only one month; and August 2, 2002 if the Approval Deadline is
extended for two months), at the office of Purchaser in Arlington, Virginia, or
at such other time and place as Seller and Purchaser shall agree in writing. If,
pursuant to Section 5.04, the Initial Closing occurs with respect to fewer than
all of the Projects, or shall occur in separate stages, then (i) the Closing
with respect to a given Project shall be deemed to mean the execution and
delivery of all of the documents contemplated under Sections 6.02 that relate
solely to said Project, the Venture Companies for said Project or the Simon
Ownership Interests for said Project, and the payment of the Cash Balance
applicable to said Closing, subject to adjustment as provided in Section 6.03,
all as provided in this Article VI, and (ii) the term "Closing Date," as it
relates to any Project, shall be the date on which the Closing with respect to
said Project is required to occur, subject to the satisfaction of all the terms
and conditions of this Agreement.

         Projects, the Venture Companies or the Simon Ownership Interests,
         except as provided in Section 6.03(b) below. In particular, there
         shall be no proration of any matter customarily prorated in connection
         with a real estate closing. At Closing, except as expressly provided
         below, all assets and liabilities of each Venture Company (including,
         without limitation, accounts payable, accounts receivable, trademarks,
         tradenames and cash (including security deposits, reserves, and any
         amounts required to be maintained on deposit with Project Lenders))
         shall remain the property of (or, as the case may be, an obligation
         of) the applicable Venture Company, with no adjustment or credit to
         Seller.

  (b)    DISTRIBUTIONS.  At the Closing, Seller shall be entitled to the
         following cash distributions with respect to the operations of the
         Venture Companies:

      (i)  To the extent not previously paid or otherwise paid prior to Closing,
           distributable cash from the operation of the Venture Companies for
           the fiscal quarter ending March 31, 2002 will be calculated and
           distributed to Simon in the same manner as distributable cash for
           fiscal year 2001 was calculated and distributed (i.e., adjusted funds
           from


                                       14
<PAGE>


           operations, or FFO based on actual first quarter results), with
           the following additional adjustments: (u) adjustment for net
           recoveries as set forth in the FY2002 Project budgets, allocated
           monthly on a straight-line basis, (v) deduction of the annual rent
           abatement as set forth in the FY2002 Project budgets as set forth in
           SCHEDULE 6.03(e) attached hereto, allocated monthly on a
           straight-line basis, (w) adjustment for percentage rent as set forth
           on SCHEDULE 6.03(d) attached hereto, (x) deduction for bad debt
           reserves as normally determined, but including an additional amount
           to reserve one hundred percent (100%) of litigation receivables,
           (y) deduction for property capital expenditures as set forth on
           SCHEDULE 6.03(a) attached hereto, and (z) adjustment for budgeted
           tenant improvement costs and other tenant capital costs, based on the
           applicable percentage(s) of minimum rents specified in the FY2002
           Project budgets, as set forth on SCHEDULE 6.03(b) attached hereto.

     (ii)  To the extent not otherwise paid prior to Closing, at Closing Simon
           will receive distributions with respect to the period of April, 1,
           2002 through the Closing Date in accordance with budgeted
           distributable cash specified in the FY2002 Project budgets, as set
           forth on SCHEDULE 6.03(c) attached hereto. Such amounts shall not be
           adjusted (upward or downward) on account of positive or negative
           variances between budgeted and actual results. For the purpose of
           calculating the distributions payable to Seller under this Section
           6.03(b)(ii), if the Closing occurs on the first day of a calendar
           month then distributions payable to Simon will be calculated through
           the preceding calendar month and if the Closing occurs on a day other
           than the first day of a calendar month then the distributions for
           such month will be prorated on a per diem basis and the actual number
           of days in such month, with Simon receiving the amount attributable
           to the period from the first day of such month through and including
           the day immediately preceding the Closing.

    (iii)  Distributable cash otherwise payable to Simon pursuant to this
           Agreement shall not be reduced by the amount of any payments of
           distributable cash from fiscal year 2001, even if such payments were
           made during fiscal year 2002. Distributions actually paid to Simon
           (whenever paid) on account of the fiscal quarter ending March 31,
           2002 or on account of subsequent periods, including payments of
           Simon's "preferential return" under the Organizational Documents,
           shall be credited against the amounts otherwise due to Simon under
           Section 6.03(b)(i) or Section 6.03(b)(ii), respectively.

     (iv)  Notwithstanding anything to the contrary set forth in the
           Organizational Documents, the distributions and other amounts payable
           to Simon under Section 6.03(b)(i) and Section 6.03(b)(ii), shall be
           final at Closing and shall not be subject to post-Closing
           reproration, reconciliation or adjustment based on actual operating
           results or otherwise.

  (c)    ASSET MANAGEMENT FEE.  The applicable Venture Companies will continue
         to pay the asset management fees payable to Simon pursuant to the
         Master Agreement through the Closing, based on budgeted revenues set
         forth in SCHEDULE 6.03(c) (rather than actual revenues); PROVIDED,
         however, if the Closing occurs on the first day of a calendar month
         then the asset management fee payable to Simon will be calculated
         through the preceding calendar month and if the Closing occurs on a
         day other than the first day of a calendar


                                       15
<PAGE>

         month then the asset management fee for such month will be prorated on
         a per diem basis and the actual number of days in such month, with
         Simon receiving the amount attributable to the period from the first
         day of such month through and including the day immediately preceding
         the Closing.

SECTION 6.04  CLOSING COSTS.

  (a)    THIRD PARTY CONSENTS.  The costs and expenses of obtaining requisite
         governmental and other third party consents and approvals (including
         administrative fees and similar costs payable to governmental agencies,
         Project Lenders, rating agencies and other parties to the
         organizational documents who may have approval rights) will be paid 50%
         by Purchaser and 50% by Seller.

  (b)    RECORDING FEES, ETC.  Recording fees, transfer taxes and similar
         Closing costs and expenses (if any) that may be payable in connection
         with the transactions contemplated under this Agreement shall be paid
         50% by Purchaser and 50% by Seller. The parties will cooperate to
         minimize such costs and expenses.

  (c)    OTHER COSTS AND EXPENSES.  Except as provided above, Purchaser and
         Seller shall each be responsible for its own costs and expenses in
         connection with this transaction, including the fees of its respective
         attorneys and advisors.

SECTION 6.05  POST-CLOSING PAYMENT.

  (a)    CANDLESTICK MILLS. If, at any time prior to or after the Closing, Mills
         abandons pursuit of the Candlestick Mills Potential Development and
         records on its books related pursuit costs of $2,500,000 or more as a
         loss or expense, then, within thirty (30) days thereafter (or at the
         first Closing, if Mills records such costs as a loss or expense prior
         to the first Closing), Seller shall reimburse Mills for up to Five
         Hundred Thousand Dollars ($500,000.00) of pursuit costs incurred with
         respect to the Candlestick Mills Potential Development over and above
         such pursuit costs giving rise to the loss or expense recorded by Mills
         on its books. This obligation shall survive the Closing in perpetuity.

relative to said Project shall continue to be operated in the ordinary course of
business through the Closing with respect to said Project, in accordance with
the terms of the applicable Organizational Documents and historical budgets and
operations (including, without limitation, maintenance and use of reserves, and
frequency of distributions); provided, however, that (i) the proposed leases to
"Casual Corner" at Ontario Mills and to "Comp USA" at Grapevine Mills shall be
deemed approved and shall not require Simon's further consent or approval under
the applicable Organizational Documents, and (ii) from and after the
satisfaction of the conditions precedent with respect to any Project, Simon
shall promptly approve any new lease for such Project if such


                                       16
<PAGE>


approval is requested by Purchaser; provided that Simon shall have no liability
or obligation thereunder, and (iii) with respect to the Arundel Mills G-2 Block,
Simon shall cooperate with Mills in connection with the transfer of the G-2
Block to Mills or its designee and/or the financing of the G-2 Block, including
(without limitation) executing any deeds or consents that may be reasonably
required, provided that Simon shall not incur any liabilities, costs or expenses
as a consequence thereof, and provided further that Mills will indemnify Simon
from any and all liabilities, costs and expenses which arise therefrom.

                                  ARTICLE VIII.

                            CASUALTY AND CONDEMNATION

Section 8.01  Casualty and Condemnation.  The rights and obligations of
Purchaser and Seller under this Agreement shall not be affected by the
occurrence of any fire or other casualty with respect to any Project, or the
occurrence of any pending or threatened condemnation proceeding with respect to
any Project; PROVIDED, however, if as consequence of any such casualty or
condemnation proceeding the applicable Project Lender accelerates the applicable
Mortgage Loan or does not allow the borrower to apply the proceeds to the repair
and restoration of the applicable Project, then Purchaser shall have the right
to terminate this Agreement with respect to such Project, upon notice to Seller
within thirty (30) days after notice from the Project Lender that it intends to
take such action, and, if applicable, at Purchaser's election the Closing Date
with respect to such Project shall be adjourned to the date which is thirty (30)
days after the Project Lender notifies the borrower that it intends to take such
action . To the extent that casualty or condemnation proceeds are received by
any Venture Company prior to Closing, said proceeds shall remain the property of
said Venture Company and shall not be distributed to (and Seller shall not
receive a credit for) the amount of any such proceeds.

                                   ARTICLE IX.

discretion, Seller may (a) terminate this Agreement upon not less than thirty
(30) days prior written notice to Purchaser, provided that Purchaser shall not
cure said default within said period of time (and upon such termination, this
Agreement shall be null and void as to any Projects with respect to which a
Closing has not previously occurred, and as to such Projects neither party shall
have any rights or obligations under this Agreement except those that

FEE"), (i.e., the increased proceeds that would have been payable to Simon in
connection with the sale of the G-2 Block to Mills if the purchase price for the
