          (b) In the event of termination pursuant to this Section 2.5, this

liability on the part of any party hereto, or their directors, officers, agents,
representatives or stockholders, except for the liability of a party for breach
of this Agreement and except as provided in clause (c) below.

          (c) If this Agreement shall be terminated pursuant to Section

the conditions set forth in Sections 2.3(d), (e), (i) and (1) have not been

neither GGP nor any of its Affiliates shall, and each of GGP and its Affiliates
agree not to, acquire, directly or indirectly, all or any portion of the Homart
Assets for a period of eighteen (18) months following the date this Agreement is
so terminated. Nothing in the foregoing shall be deemed to preclude or limit any
other Stockholder, other than a Non-Funding Stockholder, in the case of clause
(1), or GGP and its Affiliates, in the case of clause (2), from


                                      -19-



acquiring all or any portion of the Homart Assets if this Agreement shall be

                                  ARTICLE III.

                         GOVERNANCE; BOARD OF DIRECTORS

          3.1. Action by Stockholders to Effectuate this Agreement. Each
Stockholder agrees to take all actions necessary to carry out and effectuate the
provisions of this Agreement, including to vote its shares of Common Stock (to
the extent it has voting rights) in a manner consistent with this Agreement and
to cause any director elected by it (if it has the right to elect directors) to
take such actions as are required to be taken by this Agreement.

          3.2. Classes of Common Stock: Number of Directors: Voting Rights.

          (a) The Stockholders hereby acknowledge and agree that, except as
otherwise provided herein, (i) the Company shall have three classes of Common
Stock: Class A Common Stock, Class B Common Stock and Class C Common Stock, (ii)
the shares of Class A Common Stock and Class B Common Stock shall have voting
rights and shall each be voted as a separate class, with each share of Common
Stock entitled to one vote per share and all resolutions of the Class to be
adopted by a vote of a majority of the shares of the Class voted, (iii) the
shares of Class C Common Stock shall have no voting rights except as may be set
forth in this Agreement and except as may be required under the GCL
notwithstanding a provision to the contrary in this Agreement or the Company's
Certificate of Incorporation, any such voting rights to be exercised as a
separate class, with each share of Class C Common Stock entitled to one vote per
share, (iv) the Board of Directors of the Company shall consist of six
directors, (v) the shares of Class A Common Stock shall have the right to elect
three directors to the Board (the "Class A Directors"), with such directors to
be elected by a majority of the shares voted, and (vi) the shares of Class B
Common Stock shall have the right to elect three directors to the Board (the
"Class B Directors"), with such directors to be elected by a majority of the
shares voted; provided, however, that if any holder of Class A Common Stock or
Class B Common Stock shall be a Defaulting Stockholder, all of the shares of
such Class, whether or not held by the Defaulting Stockholder, shall
automatically become shares of Class C Common Stock. The Stockholders agree
that, so long as both Class A Common Stock and Class B Common Stock is
outstanding, the Class A Directors shall


                                      -20-



have the right and authority to designate all of the officers and directors of
the Subsidiaries, subject to the approval of the Class B Directors, which
approval shall not be unreasonably withheld.

          (b) If at any time shares of either Class A Common Stock or Class B
Common Stock (but not both) shall be outstanding, then (i) the Board of
Directors shall consist of seven directors, at least a majority of which shall
be comprised of Persons independent of the holder or holders of the Electing
Class; (ii) the remaining class of Common Stock entitled to vote for directors
(the "Electing Class") shall be entitled to elect six of the directors of the
Company with such directors to be elected by a majority of the shares of the
Electing Class; and (iii) the holders of Class C Common Stock shall be entitled
to elect one director with such director to be elected by a majority of the
outstanding shares of Class C Common Stock voting for this purpose as a Class,
with each share of Class C Common Stock entitled to one vote per share. For
purposes of this Agreement, (1) if the Class A Common Stock is the Electing
Class, a Person shall be deemed to be independent if such Person is not an
Affiliate or employee of GG Properties, GGP or any of their successors or any of
their Affiliates, provided, however, that no director shall be deemed not to
qualify as independent solely because such director is a director of GG
Properties, (2) if the Class B Common Stock is the Electing Class, a Person
shall be deemed to be independent if such Person is not an Affiliate or
employee of any holder of Class B Common Stock or any of its Affiliates, (3) so
long as there is an Electing Class, a director elected by the holders of Class C
Common Stock shall be deemed an independent director and (4) if there is no
Electing Class, a Person shall be deemed to be independent if such Person is not
an Affiliate or employee of any holder of Class C Common Stock or any of its
Affiliates.

          (c) If at any time the shares of neither Class A Common Stock nor
Class B Common Stock shall be outstanding, then (i) the Board of Directors shall
consist of seven directors, at least a majority of which shall be comprised of
Persons independent of the holder or holders of the Class C Common Stock and
(ii) the shares of Class C Common Stock shall be entitled to equal voting rights
and powers and shall be voted together as a single class with respect to all
matters on which stockholders may be entitled to vote (including the election of
directors), with each share of Class C Common Stock entitled to one vote per
share.

          (d) Directors on the Board shall not receive compensation unless such
directors are independent directors


                                      -21-



elected pursuant to clause (b) or (c) above in which case such independent
directors may be paid reasonable and customary compensation as determined by the
Board. Directors shall be entitled to indemnification from the Company as
provided in the Company's Certificate of Incorporation and By-laws.

          3.3. Initial Directors. To carry out the provisions of Section 3.2,
simultaneously with, or immediately following the Closing, GGP, as the sole
Class A Stockholder, and NYSCRF, as the sole Class B Stockholder, hereby elects
the following designated persons as Class A Directors and Class B Directors,
respectively, to serve until the first annual meeting of the Stockholders and
until each such director's successor has been elected and qualified to be
effective as of the Closing Date.

     Class A Directors   Matthew Bucksbaum
                         Robert A. Michaels
                         John Bucksbaum

     Class B Directors   Alan C. Sullivan
                         Martin S. Levine
                         Frank L. Sullivan, Jr.

          3.4. Subsequent Election of Directors. (a) Except as otherwise
provided herein, meetings of any class of stockholders entitled to vote for the
election of directors' may be convened for the purpose of electing the directors
of such class, or for the removal or replacement of such directors, or such
election, removal or replacement may be accomplished by written consent of
stockholders of the class in lieu of a meeting or otherwise.

          (b) Any Class A Director shall also be a director or an executive
officer of GG Properties holding the office of executive vice president or
higher.

          3.5. Removal and Replacement of Directors. The Stockholders agree
that, except as otherwise provided herein, no director may be removed from
office except by a vote of the shares of the class of Common Stock which elected
such director. The Stockholders also agree that the shares of the class of
Common Stock which elected such director shall have the exclusive right, with or
without cause, to vote for the removal of such director from the Board and to
nominate and elect a replacement director therefor.

          3.6. Officers; Management; Dissolution in the Event of Cause. (a)
Subject to the last sentence of Section


                                      -22-



3.2(a), the officers of the Company and the Subsidiaries shall consist of the
Persons designated by the Board, and such Persons shall serve in the offices
designated by the Board until their respective successors are duly appointed by
the Board. Provided both Class A Common Stock and Class B Common Stock is
outstanding, the Class A Stockholders and the Class B Stockholders agree to
cause the Class A Directors and Class B Directors, if any, to designate the
Chief Executive Officer, President, Chief Operating Officer, Chief Financial
Officer, Treasurer and Secretary of GG Properties to serve ex officio as the
Chief Executive Officer, President, Chief Operating Officer, Chief Financial
Officer, Treasurer and Secretary of the Company and of the Subsidiaries (the
"General Growth Officers"). So long as the General Growth Officers are officers
of the Company, the Class A Stockholders and the Class B Stockholders agree to
cause the Class A Directors and Class B Directors to designate certain persons
identified by any of the General Growth Officers as vice presidents, assistant
treasurers or assistant secretaries of the Company and/or its Subsidiaries.

          (b) The officers of the Company or of any Subsidiary shall be
authorized to manage the business and affairs of the Company and its
Subsidiaries subject to the direction and supervision of the Board. The General
Growth Officers, so long as they shall serve as the management of the Company,
shall manage the Company and each of the properties owned by the Company and its
Subsidiaries in a manner substantially consistent with their management of GGP
and GG Properties. Without in any way limiting the generality of the foregoing,
the officers of the Company shall manage the day to day operations of the
Company's properties and those of its Subsidiaries in accordance with the
policies and other matters set forth on Schedule VII. All costs and expenses
incurred in connection with the management of the Company and the ownership,
operation, management and development of the Company's properties and those of
its Subsidiaries shall be paid by the Company, or if paid by GGP or any of its
Affiliates, the Company shall reimburse GGP or its Affiliate therefor; provided,
however, that for so long as the General Growth Officers are the officers of the
Company, the costs and expenses listed on Schedule IX hereto shall be paid by
GGP or its Affiliates and shall not be charged to the Company or paid from
Company assets. So long as the General Growth Officers are the officers of the
Company, the Company shall pay to GGP or its Affiliates (as provided below) the
fees and reimbursable amounts in the amounts and in the manner set forth on
Schedule X. Unless otherwise approved by the Board, and except as may otherwise
be provided in this Agreement, no


                                      -23-



other fee or compensation shall be paid by the Company to GGP, GG Properties or
any of their Affiliates in connection with the management of the Company, its
properties and the properties of its Subsidiaries. So long as the General Growth
Officers are the officers of the Company, the General Growth Officers shall be
authorized to enter into one or more agreements with GGP and any of its
Affiliates to delegate all or any portion of the managerial responsibilities of
the General Growth Officers to such entities; provided that, (i) the General
Growth Officers shall not be relieved of their obligation to manage the Company
or any other obligation or responsibility under this Agreement by reason of such
delegation, (ii) the Company shall not incur any additional cost by reason of
such delegation and (iii) GGP and any such Affiliate shall be obligated to carry
out their delegated managerial responsibilities in accordance with the policies
set forth on Schedule VII to the extent applicable. Any such agreement entered
into by the Company and GGP or any of its Affiliates may provide that all or any
portion of the fees and reimbursable amounts set forth on Schedule X be paid to
an Affiliate of GGP, rather than to GGP, and may contain customary indemnities
from the Company to GGP and such Affiliate against claims, losses, liabilities,
costs and expenses arising out of the operation or management of the Company's
properties, other than such claims, losses, liabilities, costs and expenses
caused by the gross negligence or wilful misconduct of GGP or such Affiliate.
Any such agreement shall be terminable by the Company immediately following the
General Growth Officers ceasing to serve as the Company's management or
otherwise as required to effectuate the terms of this Agreement. Unless
otherwise approved by the Board, the Company and its wholly-owned Subsidiaries
shall not have any employees.

          (c) The Class B Directors shall have the right, in their sole
discretion, to cause the Company to distribute certain of the Company's
properties to the Distributee in the manner described in Section 8.1(f) in the
event that Cause exists. If the Class B Directors elect to so cause the Company
to distribute certain of its properties, (i) the Class B Stockholders shall be
considered the Offeror and the Class A and Class C Stockholders shall be
considered the Offeree for purposes of Section 8.1(f), (ii) the first
distribution of properties shall occur as soon as practicable in the tax year in
which the election is made and (iii) notwithstanding anything to the contrary in
Section 8.1(f), the Offeror shall have the right to select the first property.


                                      -24-



          (d) For purposes of this Agreement, "Cause" shall mean, (i) the
failure of the General Growth Officers to submit an Annual Business Plan to the
Board as provided in Section 3.10(c) hereof, (ii) the failure of the General
Growth Officers to obtain prior Board approval (as part of an approved Annual
Business Plan or otherwise) for any of the matters enumerated in Section
3.10(d), (iii) the General Growth Officers taking or causing the Company to take
any action materially in contravention of an approved Annual Business Plan, (iv)
a wilful and material violation by GGP or GG Properties of the provisions of
Section 4.6 hereof or (v) the engaging by any General Growth Officer, GGP, GG
Properties, the Property Manager, if any, or the Development Manager, if any, in
wilful misconduct, including, without limitation, fraud, embezzlement or theft,
which is demonstrably and materially injurious to the Company; provided that
Cause shall not be deemed to exist until the procedures set forth in Section
3.6(e) have been complied with.

          (e) If the Class B Stockholders or Class B Directors believe that an
event giving rise to Cause has occurred, the Class B Stockholders or Class B
Directors shall deliver a notice (the "Cause Notice") to the General Growth
Officers setting forth with particularity the event giving rise to Cause and the
applicable clause of Section 3.6(d). If the event giving rise to Cause is one
enumerated in Section 3.6(d)(i), (ii) or (iii), the General Growth Officers
shall have fifteen (15) days from the date of the delivery of such notice to
cure the action or failure to act (or if such action or failure to act, or
consequence of such action or failure to act, is curable but is of such a nature
that it cannot be cured within such fifteen (15) day period, the General Growth
Officers shall commence such cure and proceed diligently to complete the curing
thereof as promptly as practicable). The General Growth Officers shall promptly,
and, in any event, by the end of the fifteen (15) day cure period, notify (the
"Cure Notice") the Class B Stockholders and the Class B Directors that either
(i) the event giving rise to Cause has been cured and specifying the actions
taken with respect thereof or (ii) the event giving rise to Cause is curable but
cannot be cured within fifteen (15) days and specifying the actions that have
been taken and will be taken in respect thereof. Unless the Class B Stockholders
or Class B Directors reasonably object in writing to the Cure Notice within ten
(10) days of delivery thereof, the event giving rise to Cause shall be deemed to
be cured. If GGP wishes to contest the existence of Cause, the General Growth
Officers shall within ten (10) days of receipt of the Cause Notice, or, if the
Class B Stockholders or Class B Directors have reasonably objected to the Cure


                                      -25-



Notice, the Class B Stockholders or Class B Directors shall within ten (10) days
of receipt of the Cure Notice, submit the existence of Cause to arbitration
pursuant to Section 11.5 hereof. If the question of Cause has been submitted to
arbitration, Cause shall not be deemed to have occurred unless and until the
arbitrators have reached a final decision that Cause exists. If the General
Growth Officers neither submit the question of Cause to arbitration nor deliver
a Cure Notice within the fifteen (15) day period following the date of the
delivery of the Cause Notice, then Cause shall be deemed to exist on the day
immediately following such fifteen (15) day period. During any arbitration
proceeding, the General Growth Officers shall use all diligent and good faith
efforts to act or cease from acting in the manner that is the subject of the
dispute. Arbitration costs shall be charged to the losing party.

          3.7. Chairman of the Board. So long as the General Growth Officers are
officers of the Company, and provided both Class A Common Stock and Class B
Common Stock is outstanding or the holders of the Class A Common Stock are the
Electing Class, the Class A Stockholders and the Class B Stockholders agree to
cause the Class A Directors and Class B Directors to designate as the Chairman
of the Board of Directors of the Company and the Subsidiaries the director
elected by the Class A Common Stock who holds the most senior position at GG
Properties (the "General Growth Chairman").

          3.8. Committees. (a) The Board shall have the power to create
committees, including an executive committee and an audit committee, and to
delegate to such committees such powers and authority as the Board may determine
and as may then be permitted by the Company's Certificate of Incorporation and
By-Laws and the GCL; provided, however, that so long as the Board is comprised
of both Class A Directors and Class B Directors, any committee established by
the Board shall have at least one member designated by the Class A Directors and
at least one member designated by the Class B Directors unless the Board
determines otherwise.

          (b) The Class A Directors shall be exclusively entitled to designate,
remove and replace the Class A committee members and the Class B Directors shall
be exclusively entitled to designate, remove and replace the Class B committee
members.

          3.9. Certificate of Incorporation; By-Laws. Each Stockholder shall
vote all Common Stock over which it may have voting power and shall take all
other actions necessary and appropriate to ensure that the Company's Certificate
of


                                      -26-



Incorporation and By-Laws do not at any time conflict with the provisions of
this Agreement and shall not vote to approve (or consent to the approval of) any
amendment to the Company's Certificate of Incorporation or By-Laws which would
be inconsistent with this Agreement.

          3.10. Actions by Directors. (a) At such times as both Class A Common
Stock and Class B Common Stock shall be outstanding, at all meetings of the
Board a quorum shall exist for the transaction of business if at least two (2)
Class A Directors and two (2) Class B Directors are present. At such times as
both Class A Common Stock and Class B Common Stock shall be outstanding, at all
meetings of any committee of the Board a quorum shall exist for the transaction
of business if at least one member designated by the Class A Directors and one
member designated by the Class B Directors are present, unless the Board shall
determine otherwise. At all other times (i.e., when the Board is constituted
pursuant to Section 3.2(b) or 3.2(c)) a quorum shall exist for the transaction
of business if at least a majority of directors or committee members are
present.

          (b) When action is to be taken by vote of the Board or any committee
thereof, each member of the Board or such committee shall be accorded one vote.
Except for the selection of officers of the Company and officers and directors
of the Subsidiaries as described in Section 2.2(e) above, each and every
corporate action taken by vote of the Board or any committee thereof shall be
authorized only by the affirmative vote of the majority of directors or
committee members, as the case may be, present at a duly constituted meeting at
which a quorum is present and acting throughout; provided that at such times as
both the Class A Common Stock and Class B Common Stock shall be outstanding and
entitled to elect directors of the Company pursuant to this Agreement, at least
one Class A Director and one Class B Director (in the case of Board meetings),
or one Class A committee member and one Class B committee member (in the case of
committee meetings), has voted in favor of such action.

          (c) On or before March 1, 1996 and on or before September 15th of each
year, commencing September 15, 1996, for each Company Asset that is operating,
is then under construction or development or is in the planning stage, the
General Growth Officers will cause to be prepared and submitted to the Board for
approval a proposed annual business plan (including an annual capital budget and
operating budget and leasing guidelines to permit the execution of leases on
behalf of the Company and the


                                      -27-



Subsidiaries without specific Board approval, which shall include figures for
minimum square foot base rental, maximum tenant improvement allowances, maximum
obligations on lease take-overs and any other leasing criteria proposed by the
General Growth Officers), such plan to be substantially in the form of the
template attached hereto as Exhibit I (each, an "Annual Business Plan"). The
proposed Annual Business Plan shall also itemize each transaction or matter
requiring approval of the Board pursuant to Section 3.10(d) (viii) below. The
General Growth Officers will also cause the Board to be provided with quarterly
updates to the Annual Business Plans. A meeting of the Board to consider an
Annual Business Plan for approval shall, unless the Board otherwise determines,
be held no sooner than 45 days following submission of the proposed Annual
Business Plan to the Board but in all cases shall be held prior to commencement
of the fiscal year to which the Annual Business Plan relates (other than with
respect to the Annual Business Plan for fiscal year 1996). Prior to such
meeting, the General Growth Officers shall make available to the Class B
Directors and their representatives and advisors such backup information with
respect to the Annual Business Plan as the Class B Directors shall reasonably
request and shall be reasonably available to consult with the Class B Directors
regarding the details of the Annual Business Plan. If the Board shall consider
for adoption a proposed Annual Business Plan for any Company Asset for any year
and shall fail to adopt it in its entirety because of disagreement as to one or
more items although the Board shall agree on other items, then the Board shall
adopt as the Annual Business Plan for such year such proposed Annual Business
Plan exclusive of the items as to which there is disagreement, provided,
however, that if there is disagreement over any item of operating expense in
such Annual Business Plan that is nondiscretionary, then the Board shall adopt
such Annual Business Plan as it relates to such nondiscretionary item of
operating expense, and provided further, however, that if there is disagreement
over any discretionary item of operating expense in such Annual Business Plan,
then the Board shall adopt such Annual Business Plan including such
discretionary item of operating expense in an amount equal to the amount
reasonably proposed for such operating expense item by management of the
Company. Expenditures for nondiscretionary items shall not be limited by amounts
set forth in an approved Annual Business Plan. "Nondiscretionary items" shall
mean items that must be paid by the Company to avoid a material adverse effect
on the business, operations or value of the Company's assets. Without limiting
the generality of the foregoing, the Stockholders acknowledge and agree that
nondiscretionary items include the minimum amount of funds needed to (i) pay


                                      -28-



and perform when due all of the Company's obligations under any notes, mortgages
and other instruments to which the Company is or shall be a party or by which it
or its assets are bound in connection with any financing, (ii) pay when due real
estate and other taxes affecting the Company Assets and insurance premiums for
the Company Assets and the Company, and (iii) comply with all laws now or
hereafter in force which shall be applicable to all or any part of the Company
Assets and the operation and management thereof (including the making of capital
expenditures required for such compliance) if the failure to comply would (A)
expose the Company, any Stockholder or any employee, agent, officer, director,
or contractor of the Company to the risk of criminal prosecution, (B) entitle
any enforcing entity to take any action which could materially and adversely
affect the business, operation or value of the Company or (C) invalidate or
impair any of the insurance maintained by the Company. Until the Annual Business
Plan for fiscal year 1996 has been prepared for and approved by the Board, the
Company shall be operated in accordance with the operating and capital budgets
referred to in Section 2.3(k).

          (d) The following matters will require approval of the Board (either
as part of an approved Annual Business Plan, as part of the operating and
capital budgets referred to in Section 2.3(k) or by separate Board action)
unless any such matters have been specifically approved pursuant to this
Agreement:

          (i) the purchase or other acquisition by the Company or any of its
     Subsidiaries of any material asset or property, but excluding purchase
     options where the cost of the option does not exceed $500,000;

          (ii) the sale, exchange or other disposition by the Company or any of
     its Subsidiaries of any Significant Company Asset;

          (iii) the development, redevelopment or expansion by the Company or
     any of its Subsidiaries of any material asset or property or any
     Significant Company Asset;

          (iv) the incurrence by the Company or any of its Subsidiaries of any
     indebtedness for borrowed money or the refinancing of any indebtedness for
     borrowed money (including, without limitation, any capital lease
     obligation) in excess of $500,000 in the aggregate in any fiscal year;


                                      -29-



          (v) the pledge, encumbrance or subjecting to liens or mortgages by the
     Company or any of its Subsidiaries of any Significant Company Asset in
     connection with a financing or refinancing;

          (vi) with respect to each "Major Expense Category" (as so denominated
     in the Annual Business Plan), the expenditure by the Company or any of its
     Subsidiaries of amounts in excess of those set forth in an approved Annual
     Business Plan, unless such amounts do not exceed 105% of the total
     expenditures set forth in such Annual Business Plan for such Major Expense
     Category or are required, in the reasonable judgment of the Company's
     management, to be expended because of an emergency involving an immediate
     threat to persons or property and the Company's management is hereby
     authorized to spend such amounts without further Board action;

          (vii) the sale, exchange or other disposition of all or substantially
     all of the assets of the Company or any of its Subsidiaries or the merger,
     consolidation, reorganization or other similar transaction involving the
     Company or any of its Subsidiaries with or into another Person, in any such
     case, whether in a single transaction or a series of related transactions;

          (viii) any material transaction (or amendment or modification to any
     transaction) with, involving or benefitting GGP, GG Properties or an
     Affiliate of GGP or GG Properties other than any current or future
     transaction between the Property Manager or the Development Manager, on the
     one hand, and a non-wholly owned Subsidiary, on the other hand, relating to
     the providing of property or development management services pursuant to
     which the Property Manager or Development Manager, as the case may be,
     shall be paid fees for such services equal to the fees currently being paid
     by such non-wholly-owned Subsidiary, provided that if the Board shall not
     include Class B Directors, such transaction shall be voted upon solely by
     the independent directors;

          (ix) the taking of any action, including the filing of a petition,
     with respect to (x) an assignment for the benefit of creditors of the
     Company or any Subsidiary, (y) the bankruptcy, insolvency, reorganization,
     dissolution (other than a dissolution pursuant to Section 8.1) or any
     similar occurrence of the Company or any Subsidiary or (z) a
     liquidation


                                      -30-



     (other than pursuant to Section 8.1) or any other occurrence that might
     result in the termination of the Company or any of its Subsidiaries;

          (x) the issuance of any Common Stock or any other capital stock of the
     Company or any of its Subsidiaries or the issuance, grant or entry into an
     agreement or arrangement providing for, options, warrants or other rights,
     interests or securities convertible into or exchangeable for any shares of
     Common Stock or any other class of capital stock of the Company or any of
     its Subsidiaries; provided, however, that (i) the Company shall not issue
     any shares of Class A Common Stock or Class B Common Stock other than
     shares that have been subscribed for under this Agreement without the
     consent of all of the shares of such class in which additional shares are
     proposed to be issued, (ii) any additional issuances shall first be offered
     to the Stockholders pursuant to the provisions of Article VII hereof, and
     (iii) the Stockholders (other than any Defaulting Stockholder) shall have
     preemptive rights to acquire any additional shares of Common Stock proposed
     to be issued by the Company in addition to those offered pursuant to
     Article VII hereof;

          (xi) the determination of the amount and timing of distributions of
     Net Disposition Proceeds;

          (xii) the determination of Reserve Amounts for any fiscal year;

          (xiii) the establishment of the Company's policy with respect to the
     appropriate levels of debt capitalization of the Company;

          (xiv) the consent to any material amendments or supplements to, or the
     making of material elections or grant of waivers of material conditions or
     the enforcement of material rights under, the Homart Stock Purchase
     Agreement, the Financing Commitment and the Existing Lender Arrangements;

          (xv) the consent to any amendments or supplements to, or the making of
     elections or grant of waivers of conditions or the enforcement of rights
     under, the Natick Mall Agreement, the Management Transfer Agreement or the
     Sublease, provided, however, that in connection with any Board resolutions
     with respect to such matters, the Class A Directors shall not have the
     right to vote and the Class A Directors vote shall not be required for the
     approval of any such action;


                                      -31-



          (xvi) the engagement or retention by the Company of any property or
     development manager for any of the Company's properties or those of its
     wholly-owned Subsidiaries other than GGP, GG Properties or any of their
     Affiliates;

          (xvii) the engagement or retention by the Company of any financial
     advisor or investment banking firm for any major capital transaction or any
     legal counsel for any material litigation or Organic Change; and

          (xviii) the amendment of any of the policies set forth in Schedule VII
     hereof or any of the fees or other matters set forth in Schedule X hereof.

          (e) The Stockholders hereby approve, and the Company shall be
authorized to undertake, (i) the expansion or renovation of those properties
described on Schedule II hereto and the expenditure of funds and/or incurrence
of indebtedness in connection therewith pursuant to the expansion and renovation
budgets previously delivered to and approved by the Class B Stockholder, (ii)
the development of those properties described on Schedule III hereto and the
expenditure of funds and/or incurrence of indebtedness in connection therewith
pursuant to the development budgets previously delivered to and approved by the
Class B Stockholder, (iii) the funding and use of the Reserves as described in
Section 4.5(d) and (iv) delivery by the Board of Funding Notices to the
Stockholders permitting the Stockholders to accelerate the funding of their
Available Subscriptions as and when determined by the Board for the purposes
permitted by this Agreement.

          3.11. Meetings of the Board. (a) The Board shall meet not less
frequently than quarterly, upon notice duly given to all directors. Regular
meetings of the Board shall be held at such place as shall be determined by the
Board. Any failure to so meet shall not give rise to any presumption or
inference that the Stockholders shall have any liability for the obligations of
the Company.

          (b) Notwithstanding anything to the contrary contained in the
Company's By-Laws or the GCL, the Board shall meet upon the request of any
director conveyed in writing to each other director, at a time no fewer than two
(2) and no more than twenty-one (21) business days after such notice is given,
and at a place as determined by the Board; provided, however, attendance at such

                                      -32-



          3.12. Restrictions on Other Agreements. No Stockholder shall grant any
proxy or enter into or agree to be bound by any voting trust with respect to the
Common Stock, nor shall any Stockholder enter into any stockholder agreement or
arrangements of any kind (including agreements or arrangements with respect to
the acquisition, disposition or voting of shares of Common Stock) with any
Person with respect to the Common Stock, in either case, on terms inconsistent
with the provisions of this Agreement (whether or not such agreements and
arrangements are with other Stockholders or holders of Common Stock that are not
parties to this Agreement).

                                   ARTICLE IV.

                             OTHER CORPORATE MATTERS

          4.1. Fiscal Year; Designation of Auditors. The Company's fiscal year
shall be the calendar year. The Company's auditors shall be selected by the
Board, provided, however, that (a) such firm shall be a "Big Six" certified
public accounting firm (or any successor to any such firm) and (b) unless the
Class A Directors and Class B Directors determine otherwise, such firm shall not
be the auditors of GGP or GG Properties.

          4.2. Dividends. Subject in all cases to any applicable provisions of
the GCL, the Company shall distribute to the Stockholders at least on a
quarterly basis an amount at least equal to the Company's Operating Cash Flow
during the immediately preceding fiscal quarter, provided that the Company shall
distribute with respect to each fiscal year not less than one hundred percent
(100%) of the Company's Net Taxable Income for such fiscal year. The regular
record dates of the Company for the purpose of determining Stockholders entitled
to quarterly distributions shall be the same as the regular record dates of GG
Properties and the payment dates of the Company for regular quarterly dividends
shall be the business day immediately preceding the payment date of GG
Properties for regular quarterly dividends. GG Properties shall notify the
Company at least ten days prior to each of its regular record dates of the date
of such record date and the related payment date.

          4.3. Conduct of Business. (a) The Company shall not, directly or
indirectly, acquire any assets or businesses other than the Stock (as defined in
the Homart Stock Purchase Agreement) and the Homart Assets except in connection
with the holding, development, redevelopment, expansion, renovation, operation
and otherwise dealing with


                                      -33-



the Homart Assets (including (i) the development of the Properties Currently
Under Development, (ii) the development of the planned regional malls listed on
Schedule XIII hereto, (iii) the development of all or a portion of the vacant
land included as part of the Homart Assets and (iv) the acquisition of land or
properties adjacent to the real property constituting the Homart Assets and
third parties' interests in the partnerships or joint ventures constituting the
Homart Assets).

          (b) The Company shall conduct its affairs in a manner that will not
cause the Company to be deemed to be, and will not make any investment which
could cause it to become, an "investment company" for purposes of the Investment
Company Act.

          4.4. Operation in Accordance with REIT Requirements and Other Matters.
(a) The Company shall operate in a manner that will enable the Company to (i)
satisfy the requirements for qualifying as a real estate investment trust under
the Code and (ii) avoid any federal income or excise tax liability and shall
file an election to be taxed as a real estate investment trust for its first
taxable year and, from and after January 31, 1996, the Company shall at all
times ensure that the Company shall have no less than 100 holders of its capital
stock.

          (b) The Company shall at all times operate, and each Stockholder shall
cause the Company to operate in a manner so that it will be treated as an
"operating company" under Pension and Welfare Benefits Administration Regulation
Section 2510.3-101 (the "Plan Asset Regulations") issued by the Department of
Labor under Title I of the Employee Retirement Income Security Act of 1974, as
the same may be amended from time to time ("ERISA") as long as equity
participation by Benefit Plan Investors (as defined in the Plan Asset
Regulations) is "significant," as defined therein.

          (c) The Company shall endeavor to operate and structure its
investments in a manner so as to minimize, to the extent reasonably possible and
to the extent not inconsistent with the best interests of the Company, the
amount of unrelated business taxable income recognized by Stockholders that are
pension funds or educational institutions exempt from Federal income taxes.

          4.5. Sources and Uses of Funds; Organizational Expenses;
Reorganization Expenses; Reserves. (a) On the Homart Closing Date, (i) the
Company will use the Initial Subscriptions to fund the purchase price under the
Homart Stock Purchase Agreement, to pay the organizational expenses


                                      -34-



described in Section 4.5(b), to pay to GGP the reorganization costs described in
Section 4.5(c) and to partially fund the Reserves referred to in Section 4.5(d),
(ii) the Company and/or its Subsidiaries shall incur the indebtedness, or
refinance the existing indebtedness, to the extent contemplated in the Financing
Commitment and the Existing Lender Arrangements, and (iii) the Company or its
Subsidiaries shall close under the Natick Mall Agreement, the Management
Transfer Agreement and the Sublease.

          (b) Each Stockholder hereby acknowledges and agrees that all expenses
that are listed under the category of "Expenses Billed to Date" on Schedule XIV
hereto and amounts listed under the category of "Estimated Expenses to be
Incurred After the Closing" on Schedule XIV hereto, in each case that have been
or will be incurred by or on behalf of the Company on or prior to the Homart
Closing Date or in connection with the closing under the Homart Stock Purchase
Agreement shall be expenses of the Company and shall be paid by the Company on
or promptly following the Homart Closing Date.

          (c) On the Homart Closing Date, the Company shall pay to GGP from the
Initial Subscriptions made to the Company or from other funds available to the
Company the amount of $10,000,000.00 to reimburse GGP and its Affiliates for
various restructuring and transition costs that GGP and its Affiliates have
incurred and will continue to incur in connection with reorganizing and
combining the organization of Homart Development Co. with GGP and its Affiliates
as set forth on a schedule previously delivered to and approved by the Class B
Stockholder. Any such costs incurred in excess of $10,000,000.00 will be the
responsibility of GGP and its Affiliates, as applicable, and will not be the
responsibility of the Company.

          (d) (i) The Company shall establish and fund either on the Homart
     Closing Date or over time from the Initial Subscriptions and Funded
     Subscriptions made to the Company or from other capital resources available
     to the Company certain reserves in the specified amounts set forth on
     Schedule XV hereto (the "Special Reserves") with respect to certain
     liabilities which are estimated to be incurred by the Company through
     December 31, 1999. Any costs incurred with respect to such liabilities
     which exceed the amounts available under the Special Reserves, except for
     those liabilities set forth in clause (ii) below, will be for the account
     of the Company. Any Special Reserves that are not expended will be retained
     by the Company for other Company purposes. The Board may from time to


                                      -35-



     time reduce the amount of the Special Reserves either by making a special
     dividend to the Stockholders (which special dividend shall not be deemed to
     be a part of any dividend made pursuant to Section 4.2) or by reallocating
     Available Subscriptions for other purposes.

          (ii) The following Special Reserve liabilities represent liabilities
     due from the Company to GGP with respect to GGP obligations arising as a
     result of the Management Transfer Agreement: liabilities incurred by GGP
     for hiring bonuses to Homart employees being employed by GGP following the
     Homart Closing Date for which the Company will indemnify GGP, and reimburse
     GGP, to the extent set forth in Schedule XV, such reimbursement to be made
     at the Homart Closing Date.

          4.6. Other Activities of Stockholders. (a) Neither GGP nor GG
Properties nor any of their Affiliates shall, directly or indirectly, as an
owner, managing or general partner, majority or controlling stockholder,
consultant, joint venturer, manager or otherwise, acquire, develop, redevelop,
improve, construct or manage any regional shopping mall project, that is, in any
such case, located within the trade area (as shown in red on the maps attached
hereto as Exhibit J) of any of the mall shopping centers listed on Exhibit J
hereto (the "Relevant Trade Area"); provided, however, that nothing herein shall
prohibit or restrict GGP or GG Properties or any of their Affiliates from
owning, operating, developing, improving, expanding or managing any of the mall
shopping centers owned, operated, being developed or managed, directly or
indirectly, by any of them on the date hereof and listed on Schedule XVI hereto
and; provided further, however, that GGP, GG Properties and their Affiliates
shall have until June 30, 1996 to divest its management position at the Dutch
Square Mall located in Columbia, South Carolina, and the Southdale Mall located
in Minneapolis, Minnesota. If, as manager of the Visalia Mall located in
Visalia, California, GGP or its Affiliate engages in any active discussions with
a new department store interested in locating at such mall, GGP shall disclose
such fact to the Board, and the Class B Directors shall have the exclusive right
to determine whether a conflict exists. If the Class B Directors so determine
that a conflict exists, GGP or its Affiliate shall divest itself of its
management position with respect to the Visalia Mall as soon as practicable.

          (b) Notwithstanding anything to the contrary in Section 4.6(a),
neither GGP nor GG Properties shall be in breach of Section 4.6(a) if, in
connection with the


                                      -36-



acquisition of a portfolio of three or more properties or management contracts,
GGP, GG Properties or any of their Affiliates acquires, or becomes the property
manager or development manager for, any regional shopping mall project that is
located within the Relevant Trade Area (the "Competing Asset"); provided GGP, GG
Properties or such Affiliate terminates any management position with respect to
such Competing Asset as soon as possible but no later than within one year.

          (c) Subject to Section 4.6(a) and (b), each Stockholder may engage or
invest in any other activity or venture or possess any interest therein
independently or with others. None of the Stockholders, the Company or any other
Person employed by, related to or in any way affiliated with any Stockholder or
the Company shall have any duty or obligation to disclose or offer to the
Company or any of the Stockholders, or obtain for the benefit of the Company or
any of the Stockholders, any such other activity or venture or interest therein.
None of the Company, the Stockholders, the creditors of the Company or any other
person having any interest in the Company shall have (i) any claim, right or
cause of action against any of the Stockholders or any other Person employed by,
related to or in any way affiliated with, any of the Stockholders by reason of
any direct or indirect investment or other participation, whether active or
passive, in any such activity or venture therein or (ii) any right to any such
activity or venture or interest therein or the income or profits derived
therefrom.

          4.7. Reports and Statements. (a) Not later than 45 days after the end
of each fiscal quarter (other than the fourth quarter), the Company shall
prepare (or cause to be prepared) and mail to each Stockholder an unaudited
report (prepared in accordance with generally accepted accounting principles)
setting forth as of the end of such fiscal quarter:

          (i) a balance sheet of the Company and of the Subsidiaries on a
     consolidated basis; and

                                   ARTICLE V.

                                 EXCHANGE RIGHT

          5.1. The Exchange Right. (a) At any time after the Exchange Trigger
Date, each Class B Stockholder and Class C Stockholder (an "Exchanging
Stockholder") shall have the right from time to time, upon delivery to GG
Properties of a written election notice (the "Exchange Election Notice"), to
exchange all or a portion of its Common Stock (other than with respect to any
shares of Class C Stock that have been acquired from GGP or GG Properties,
unless GGP or GG Properties, as part of the transaction by which such shares
were acquired, consents to the application of this Section 5.1 to such
shares) for consideration from GG. Properties equal to:

          (i)  the product of (x) the Company's FFO for the most recently
               completed four fiscal quarters for which the report of the
               Company's FFO and the General Growth FFO referred to in Section
               4.7(e) has been delivered to the Stockholders prior to the date
               of the Exchange Election Notice (the "Measurement Period"),
               adjusted as set forth below and calculated on the same basis as
               the General Growth FFO multiplied by (y) the Proportionate Share
               represented by the shares of Common Stock being exchanged,
               multiplied by

          (ii) an amount equal to (1) the Ten Day Average General Growth Share
               Closing Price divided by (2) the General Growth FFO Per share for
               the Measurement Period adjusted as set forth below:

          (b) Calculation of the Company's FFO or the General Growth FFO shall
be adjusted so as to give pro forma effect to (i) the incurrence of debt or
issuance of capital stock by the Company and its Subsidiaries or by GG
Properties or GGP, as the case may be, during the Measurement Period or
subsequent to the end of the Measurement Period through the date of the Election
Notice as if such debt or capital stock had been incurred or issued, as the case
may be, and the application of the proceeds from the incurrence or issuance, as
the case may be, of such debt or capital stock had occurred at the beginning of
the Measurement Period, (ii) the repayment or elimination of any debt of the
Company or any Subsidiary or of GG Properties or GGP, as the case may be
(including a


                                      -40-



pro-forma repayment or elimination of debt (assuming such debt bears interest at
the Company's weighted average cost of debt) as a result of (1) any Additional
Subscription Payments received from an Exchanging Stockholder in conjunction
with the exercise of its exchange rights under this Article V and (2) a
corresponding deemed receipt of any Additional Subscription Payments from the
holders of Class A Common Stock whether or not actually funded), or the
repurchase or redemption of any capital stock of the Company or any Subsidiary
or of GG Properties or GGP, as the case may be, during the Measurement Period or
subsequent to the end of the Measurement Period through the date of the Election
Notice as if such debt had been repaid or eliminated or such capital stock had
been repurchased or redeemed at the beginning of the Measurement Period, and
(iii) any asset disposition and any asset acquisition by the Company or any
Subsidiary or by GG Properties or GGP, as the case may be, the gross proceeds or
gross purchase price of which, as the case may be, exceeds $1 million and that
occurred during the Measurement Period or subsequent to the end of the
Measurement Period through the date of the Election Notice as if such asset
disposition or asset acquisition had occurred at the beginning of the
Measurement Period; provided further that, in making such calculations, the
interest expense attributable to interest or dividends on any debt of the
Company or any Subsidiary or of GG Properties or GGP, as the case may be, or
capital stock (other than Common Stock) of the Company or any Subsidiary or of
GG Properties or GGP, as the case may be, which bears a floating rate shall be
determined on a pro forma basis as if the rate in effect on the date of
determination had been the applicable rate for all of the Measurement Period.
The amount derived by application of clauses (a)(i) and (ii) above as adjusted
by this clause (b) is referred to herein as the " Exchange Amount."

          (c) No Stockholder may exercise the exchange right set forth in this
Section 5.1 to the extent that the transfer of such Stockholder's Common Stock
in exchange for GG Stock as set forth in Section 5.2 could, based upon a written
opinion of counsel satisfactory to such Stockholder, cause GG Properties or the
Company to fail to qualify as a real estate investment trust under the Code. No
Stockholder may deliver more than one Exchange Election Notice in any twelve
month period. No stockholder may deliver an Exchange Election Notice, for shares
of Common Stock that would result in an Exchange Amount less than $10,000,000
unless such Exchange Election Notice relates to such Stockholder's entire
remaining shares of Common Stock. No Stockholder, other than the original
signatories to this Agreement, shall have the right to exchange more than the
Maximum Number of


                                      -41-



Shares of Common Stock pursuant to this Article V in any twelve month period.
The term "Maximum Number of Shares of Common Stock" shall mean the greater of
(i) one half of the total number of Shares of Common Stock at any time owned
(including shares that have previously been exchanged or disposed of) by a
Stockholder and (ii) such number of shares of Common Stock as would result in an
Exchange Amount of $100,000,000 or less.

          (d) If any accounting convention, policy or procedure covering any
future expenditure, receipt, sale, purchase or other event has not been fully or
adequately addressed in the definition of General Growth FFO or Company FFO as
set forth on Exhibits B and A hereto, respectively, then any amendment to the
definition of General Growth FFO or Company FFO, as appropriate, to provide for
any such convention, policy or procedure with respect to any such event shall
require the consent of GG Properties and the Board.

          (e) On or prior to the Closing Date, GG Properties shall cause its
board of directors to adopt a resolution approving all of the transactions
contemplated by this Agreement that could be deemed to be a "business
combination" as defined in Section 203 of the GCL between GG Properties and any
Exchanging Stockholder that becomes an "interested stockholder" as defined in
Section 203 of the GCL, including, without limitation, (i) additional issuances
of GG Stock to such Stockholder in the context of exchanges under this Article V
and (ii) the acquisition by such Stockholder of properties from the Company in
the context of Article VIII hereof. GG Properties shall also cause its board
of directors to adopt a resolution authorizing any Exchanging Stockholder that
becomes an "interested stockholder" as defined in Section 203 of the GCL to vote
its shares of GG Stock received in an exchange transaction for all purposes. GG
Properties agrees that it will not adopt or otherwise approve any "poison pill"
or stockholder rights plan and would have the effect of diluting an Exchanging
Stockholder's equity interest in GG Properties upon exercise of the exchange
rights contained in this Article V or that would otherwise conflict with or
impair such exchange rights.

          (f) Any Stockholder exercising exchange rights pursuant to this
Article V shall, as a condition to such exercise, (1) have timely and fully
funded any previously required funding of all or any portion of its Aggregate
Subscription and (2) fund any unfunded portion of its Aggregate Subscription,
but, with respect to clause (2), shall not receive additional shares of Common
Stock


                                      -42-



therefor, and there shall not be any deemed receipt by any other Stockholder of
additional Shares of Common Stock in connection with such funding.

          (g) GG Properties shall insure that it has sufficient authorized but
unissued shares of Common Stock to enable it to satisfy the exchange rights of
all Stockholders hereunder, and shall, subject to obtaining necessary
stockholder approval, cause its certificate of incorporation and other corporate
charter documents to be amended from time to time, and shall solicit the consent
of its stockholders to the extent required to effectuate any such amendment. In
the event GG Properties elects to pay the Exchange Amount in GG Stock, GG
Properties shall take all steps required by applicable law and regulation and
required under its certificate of incorporation to enable GG Properties to issue
such GG Stock to the Exchanging Stockholder on the relevant closing date.

          5.2. Payment of the Exchange Amount. GG Properties shall have the
option to pay the Exchange Amount in cash or in shares of GG Stock or any
combination thereof. At any time within forty-five (45) days after the date of
the Exchange Election Notice, GG Properties shall deliver to the relevant
Stockholder a written notice (the "Exchange Amount Payment Notice") specifying
whether GG Properties has elected to pay the Exchange Amount in cash, GG Stock
or a specified combination thereof. If GG Properties fails to deliver the
Exchange Amount Payment Notice within such forty-five (45) day period in which
it affirmatively elects to pay the Exchange Amount entirely in GG Stock, GG
Properties shall be deemed to have elected to pay the Exchange Amount entirely
in cash.

          5.3. Registered Stock; Registration Statement.

          To the extent required to enable a Stockholder to publicly distribute
the GG Stock received by it in an exchange transaction, GG Properties shall
prepare and file with the Commission promptly following the delivery of an
Exchange Election Notice (to the extent not then available) a shelf registration
statement under the 33 Act registering GG Stock with respect to the GG Stock of
such Stockholder. GG Properties shall maintain the effectiveness of such shelf
registration statement with respect to such Stockholder's GG Stock, and shall
include such Stockholder as a selling Stockholder with respect to such shelf
registration statement to the extent the public distribution of such
Stockholder's GG Stock would otherwise be prohibited under the 33 Act. All
expenses of such shelf registration of GG Stock required by this Section 5.3
shall be shared equally by GG


                                      -43-



Properties and the Exchanging Stockholder. If requested by a Stockholder that is
selling GG Stock pursuant to an underwritten offering, GG Properties will
reasonably cooperate with such Stockholder in connection with such underwritten
offering, including, upon request, entering into and performing its obligations
under a customary underwriting agreement (which may include representations,
warranties and indemnities customarily given by GG Properties to its
underwriters) with the underwriters of such offering; provided that GG
Properties shall have the right to select the lead or managing underwriter for
such offering (such underwriter to be either Goldman, Sachs & Co. or one of the
top three lead underwriters of REIT equity securities for the immediately
preceding completed calendar year) and such Stockholder shall reimburse GG
Properties for all reasonable attorneys' fees incurred by GG Properties in
connection with such underwritten offering.

          5.4. Closing of an Exchange Transaction. (a) The closing of an
exchange transaction contemplated by this Article V shall occur (i) if GG
Properties has elected to pay the Exchange Amount entirely in GG Stock, on the
date set forth in the Exchange Amount Payment Notice, but in no event later than
the forty-fifth (45th) day following the date on which the Exchanging
Stockholder delivered the Exchange Election Notice or (ii) if GG Properties has
elected to pay the Exchange Amount entirely in cash, on a date set forth in the
Exchange Amount Payment Notice, which date shall in no event be later than the
one hundred twentieth (120th) day following the date on which the Exchanging
Stockholder delivered the Exchange Election Notice. If GG Properties has elected
to pay the Exchange Amount in a combination of GG Stock and cash, (A) the
closing of the delivery of GG Stock shall take place on a date set forth in the
Exchange Amount Payment Notice which date shall in no event be later than the
forty-fifth (45th) day following the date on which the Exchanging Stockholder
delivered the Exchange Election Notice and (B) the closing of the delivery of
the cash portion of the Exchange Amount shall take place on a date set forth in
the Exchange Amount Payment Notice, which date shall in no event be later than
the one hundred twentieth (120th) day following the date on which the Exchanging
Stockholder delivered the Exchange Election Notice. At the closing or closings,
which shall be held at the offices of counsel to GG Properties, (i) GG
Properties shall deliver to the relevant Stockholder the cash portion of the
Exchange Amount required to be paid to the Stockholder in immediately available
funds and, if GG Properties has elected to pay all or a portion of the Exchange
Amount with GG Stock, such certificates representing the number of shares of
such GG Stock to be


                                      -44-



delivered (calculated based on the Ten Day Average General Growth Share Closing
Price, if the closing with respect to such GG Stock occurs within seven (7)
business days of the date of the Exchange Election Notice, or (subject to
Section 5.5(b)) calculated based on (x) the Ten Day Average General Growth
Share Closing Price or (y) the average of the General Growth Share Closing
Prices for each of the ten Trading Days immediately preceding the business day
preceding the closing date, whichever would result in the issuance of the
greater number of shares of GG Stock, if the closing occurs after the seventh
(7th) business day following the date of the Exchange Election Notice)
registered in the names of the Persons designated by such Stockholder, (ii) such
Stockholder shall deliver to GG Properties the certificates representing the
Common Stock being exchanged (together with all necessary fully executed stock
powers), free and clear of any lien, claim or encumbrance (and such Stockholder
hereby represents and warrants that such Common Stock shall immediately prior to
such sale, be so free and clear), (iii) GG Properties shall deliver to GGP the
certificates representing the Common Stock being exchanged (together with all
necessary fully executed stock powers) and (iv) GG Properties, such Stockholder,
GGP and the Company shall execute such other documents and take such other
action as shall be reasonably necessary to consummate the transactions
contemplated by this Article V.

          (b) Pending the closing of an exchange transaction contemplated by
this Article V, an Exchanging Stockholder shall be entitled to all rights,
including voting rights and rights to receive dividends and distributions, that
such Stockholder would ordinarily have with respect to its shares.

          (c) Any shares of Class B Common Stock received by GGP in such an
exchange transaction shall, automatically upon consummation of the exchange
transaction, become shares of Class C Common Stock.

          5.5. Necessary Government Filings. (a) If (i) a Stockholder delivers
to GG Properties an Exchange Election Notice and (ii) as of the date of such
Exchange Election Notice, the purchase by GG Properties of such Stockholder's
Common Stock pursuant to Section 5.1 is subject to the premerger notification
and reporting requirements under the Hart-Scott-Rodino Antitrust Improvements
Act of 1976, as amended ("HSR"), and the rules and regulations thereunder (the
"Rules"), then GG Properties shall use its reasonable best efforts to (1) duly
file with the United States Federal Trade Commission (the "FTC") and the
Assistant Attorney General (as defined in Section 7A(b)(1)(A) of HSR), no later


                                      -45-

fully completed premerger notification and report form with respect to GG
Properties pursuant to Section 7A(a) of HSR and a fully completed written
request for early termination of the waiting period pursuant to Section 7A(b)(2)
of HSR and Rule 803.11 thereunder, (2) deliver to the Company (for execution and
filing by the Company), no later than the fifteenth (15th) day after the date of
the Exchange Election Notice, a fully completed premerger notification and
report form with respect to the Company as required to be filed pursuant to
Section 7A(a) of HSR and (3) cause the applicable waiting period under HSR to
terminate on or before the thirtieth (30th) day after the date of the Exchange
Election Notice.

          (b) If (i) a Stockholder delivers to GG Properties an Exchange
Election Notice and (ii) as of the date of such Exchange Election Notice, the
acquisition by such Stockholder of GG Stock in exchange for such Stockholder's
Common Stock pursuant to Section 5.1 is subject to the premerger notification
and reporting requirements under HSR and the Rules, then (A) GG Properties and
such Stockholder shall use their respective reasonable best efforts to duly file
with the FTC and the Assistant Attorney General, no later than the fifteenth
(15th) day after the date of the Exchange Election Notice, a fully completed
premerger notification and report form with respect to GG Properties pursuant to
Section 7A(a) of HSR and (B) GG Properties shall use its reasonable best efforts
to file with the FTC and the Assistant Attorney General a fully completed
written request for early termination of the waiting period pursuant to Section
7(A)(b)(2) of HSR and Rule 803.11 thereunder, and cause the applicable waiting
period under HSR to. terminate on or before the thirtieth (30th) day after the
date of the Exchange Election Notice. Notwithstanding anything to the contrary
in Section 5.4, if a Stockholder is required to make a filing under HSR pursuant
to this Section 5.5(b), and as a result thereof, the closing of the delivery of
GG Stock cannot occur on or prior to the seventh (7th) business day following
the date of the Exchange Election Notice, then the number of shares of GG Stock
to be delivered at such closing shall be calculated based upon the Ten Day
Average General Growth Share Closing Price.

          (c) If a Stockholder has delivered an Exchange Election Notice
pursuant to Section 5.1 above and GG Properties and such Stockholder have
complied with the provisions of Section 5.5(a) above but, notwithstanding GG
Properties' and such Stockholder's reasonable best efforts, the applicable
waiting period under HSR with respect to such


                                      -46-



exchange has not terminated by the closing date set forth in Section 5.4 above,
then, notwithstanding anything to the contrary in this Article V, the closing
date set forth in Section 5.4 above shall be extended to the fifth business day
after all applicable waiting periods under HSR have been terminated. From and
after the original closing date set forth in Section 5.4 above, GG Properties
shall continue to use its reasonable best efforts to cause the applicable
waiting period under HSR with respect to such exchange to be terminated.

          5.6. Board Representation. If a Stockholder exchanges its Common Stock
pursuant to this Article V, and receives as consideration for such Common Stock,
GG Stock having a value of at least $100,000,000, then at the election of such
Stockholder, GG Properties will exercise all authority under the GCL and under
GG Properties' Certificate of Incorporation and Bylaws to (i) cause one
Satisfactory Nominee (as defined below) designated by such Stockholder and to
cause one independent director nominated by the board of directors of GG
Properties (the "GG Board") (if such Satisfactory Nominee would not qualify as
an independent director) to be promptly elected to the GG Board as a member of
the class of directors whose term is the latest to expire and (ii) increase the
size of the GG Board to account for such additional director or directors. At
each annual meeting of stockholders of GG Properties thereafter at which
directors in the same class as the Satisfactory Nominee shall be elected, such
Stockholder shall be entitled to propose to the GG Board or the nominating
committee thereof one Satisfactory Nominee in accordance with the procedures set
forth below. The proposal by such Stockholder of any person for election to the
GG Board shall be made after consultation with GG Properties, each person
designated by such Stockholder for election to the GG Board shall be reasonably
acceptable to the GG Board (each such person, a "Satisfactory Nominee"). GG
Properties shall cause each Satisfactory Nominee designated by such Stockholder
for election to the GG Board to be included in the slate of nominees recommended
by the GG Board to GG Properties' stockholders for election as directors at each
annual meeting of the stockholders of GG Properties at which directors in the
same class as the Satisfactory Nominee shall be elected and shall use its best
efforts to cause the election of each such Satisfactory Nominee, including
soliciting proxies in favor of the election of such persons. In the event that
any Satisfactory Nominee elected to the GG Board shall cease to serve as a
director for any reason, the vacancy resulting therefrom shall be filled by the
GG Board with a substitute Satisfactory Nominee according to the procedures
described


                                      -47-



above. Notwithstanding the foregoing, such Stockholder shall no longer have the
right to propose a Satisfactory Nominee to the GG Board from and after the date
such Stockholder ceases to own at least $80,000,000 worth of GG Stock based on
then current market value. The parties agree that the designees of such
Stockholder on the GG Board shall not participate in any action taken by the GG
Board or GG Properties relating to this Agreement.

          5.7. GG Properties Organic Change. Any capital reorganization or
reclassification of the capital stock of GG Properties, or consolidation or
merger of GG Properties with another Person, or the sale of all or substantially
all of the assets of GG Properties to another Person which is effected in such a
way that holders of GG Stock are entitled to receive (either directly or upon
subsequent liquidation) stock, securities, cash or other property with respect
to or in exchange for GG Stock is referred to herein as an "Organic Change."
Prior to and as a condition of such Organic Change, GG Properties shall make
lawful and adequate provision to insure that the Class B Stockholders and Class
C Stockholders will thereafter have the right to acquire and receive upon
exchange of their shares of Class B Common Stock or shares of Class C Common
Stock pursuant to this Article V, in lieu of shares of GG Stock, such shares of
stock, securities, cash or other property as such Stockholders would have been
entitled to receive in connection with such Organic Change if such Stockholders
had exercised their exchange rights immediately prior to the Organic Change.
Prior to the consummation of any such Organic Change, GG Properties shall insure
that the successor Person (if other than GG Properties) resulting from such
Organic Change or the Person purchasing assets shall assume by written
instrument delivered to the Class B Stockholders and Class C Stockholders the
obligation to deliver to each such Stockholder such shares of stock, securities
or assets as, in accordance with the foregoing provisions, such Stockholder
would be entitled to receive upon exercise of its exchange rights. If a
purchase, tender or exchange offer is made to and accepted by the holders of
more than 50% of the outstanding shares of GG Stock, GG Properties shall, prior
to the consummation of any consolidation, merger or sale with the Person having
made such offer or with any Affiliate of such Person, insure that the Class B
Stockholders and Class C Stockholders shall have been given a reasonable
opportunity to then elect to receive upon the exercise of their exchange rights
pursuant to this Article V either the stock, securities or assets then issuable
with respect to the GG Stock or the stock, securities or assets, or the
equivalent, issued to previous holders of GG Stock in accordance with such
offer.

                                   ARTICLE VI.

                            TRANSFERS OF COMMON STOCK

          6.1. Certain Restrictions. No Stockholder shall, directly or
indirectly, Transfer any Common Stock to any Person (any such Person in whose
favor a Transfer of Stock is made and all subsequent permitted transferees of
any such Person being referred to collectively as "Transferees" and individually
as a "Transferee"), unless such Transfer is made pursuant to this Article VI or
Articles V or VIII hereof provided, however, that nothing in this Agreement
shall restrict the Transfer of any ownership interest in any Stockholder unless
such Stockholder's assets consist substantially of Common Sock, in which case
the Transfer shall be deemed a Transfer of such Common Stock. Each Stockholder
hereby agrees that it will not Transfer all or any portion of its Common Stock
except as permitted by this Agreement, that the Company shall not reflect on its
books any Transfer of Common Stock to any Person except in accordance with this
Agreement, and that any Transfer of Common Stock not permitted by the provisions
of this Agreement shall be null and void ab initio.

          6.2. Compliance with Securities Laws. No Stockholder shall Transfer
any Common Stock, and the Company shall not reflect on its books any Transfer of
Common Stock, unless (a) the Transfer is pursuant to an effective registration
statement under the 33 Act and under any applicable state securities or blue sky
laws or (b) such Stockholder shall have furnished the Company with evidence
reasonably satisfactory to the Company that no such registration is required
because of the availability of an exemption from registration under the 33 Act
and under applicable state securities or blue sky laws. A written opinion of
counsel of recognized standing to the effect set forth in clause (b) of the
preceding sentence shall satisfy the requirements of such clause.

          6.3. Transfer of Ownership Interests in Affiliates. Each Stockholder
hereby agrees that the Transfer by such Stockholder of any ownership interest or
right of exclusive control, if applicable, in any Person that is its Affiliate
if (i) such Person or an Affiliate of such Person that is controlled by such

longer being an Affiliate of such Stockholder, shall be deemed a Transfer of the
shares of Common Stock owned by such Person; provided, however that this Section
6.3 shall in no way limit the transfer of ownership interests or the right of
exclusive control in GG Properties or GGP.

investment of all Stockholders in the Company (based on the Aggregate
Subscription therefor) (the "Class B Minimum Investment"), then all remaining
shares of Class B Common Stock shall automatically be converted into an equal
number of shares of Class C Common Stock.

          (iv) Any holder of Class B Common Stock shall have the right, without

                                      -51-



          (2) If (1) shares of Class B Common Stock are Transferred to a Person

          6.5. Certain Prohibited Transfers of Common Stock by Stockholders. (a)
Notwithstanding any other provision of this Agreement to the contrary, no
Transfer of all or any portion of any Stockholder's Common Stock shall be made
if such Transfer would result in:

          (i) the Company being required to register, or seek an exemption from
     registration, as an investment company under the Investment Company Act; or

          (ii) the Company failing to qualify as a real estate investment trust
     under the Code.

          (b) Notwithstanding any other provision of this Agreement to the
contrary, without the prior written approval of the Class A Directors, which

                                      -52-



registered under the Investment Company Act, an investment advisor registered
under the Investment Advisors Act of 1940, as amended, acting in its capacity as
an investment advisor, or a fiduciary under ERISA acting in such capacity.

          (c) The Board may in its discretion require as a condition of any
Transfer permitted under this Article VI, the delivery of a written opinion of
responsible counsel (who may be counsel for the Company), satisfactory in form
and substance to the Board, to the effect that such Transfer would not result in
any of the consequences set forth in clause (a)(i) or (a)(ii) and shall cover
such other matters as the Board may reasonably require. In addition, a Person to
whom a Transfer may be made pursuant to this Article VI may also be required, in
the discretion of the Board, and as a condition precedent to such Transfer, to
make certain representations, warranties and covenants including, but not
limited to, representations as to such Person's net worth, sophistication and
investment intent. The Company agrees to cooperate with any Stockholder making a
Transfer by providing promptly such records and other factual information as may
be reasonably requested with respect to any proposed Transfer provided that such
Stockholder and any prospective transferee that receives such records and
information shall agree in writing to maintain the confidentiality thereof.

          6.6. Expenses of Transfer. The transferring Stockholder agrees that it
will pay all expenses, including reasonable attorneys' fees, incurred by the
Company in connection with any Transfer of its Common Stock.

          6.7. Indemnification by Transferor. In the event that the Company or
any non-transferring Stockholder becomes involved in any capacity in any action,
proceeding, or investigation brought by or against any Person (including any
Stockholder) in connection with any Transfer by a Stockholder of its Common
Stock (other than a Transfer pursuant to Article V or Article VIII hereof), the
transferring Stockholder will periodically reimburse each of the Company and any
non-transferring Stockholder for its legal and other expenses (including the
cost of any investigation and preparation) incurred in connection therewith. To
the fullest extent permitted by law, the transferring Stockholder also will
indemnify the Company and any non-transferring Stockholder against any losses,
claims, damages, or liabilities to which any of them may become subject in
connection with such Transfer. The reimbursement and indemnity obligations of
the transferring Stockholder under this paragraph shall be in addition to any
liability which the transferring Stockholder may otherwise have, shall


                                      -53-



extend upon the same terms and conditions to the partners, employees, and
controlling Persons of the Company and any non-transferring Stockholder, and
shall be binding upon and inure to the benefit of any successors, assigns,
heirs, and personal representatives of the Company, any non-transferring
Stockholder, and any such Persons. The foregoing provisions shall survive any
termination of this Agreement.

          6.8. Acceptance of Prior Acts. Any person who becomes a Stockholder
accepts, ratifies and agrees to be bound by all actions duly taken pursuant to
the terms and provisions of this Agreement by the Company and the Stockholders
prior to the date it became a Stockholder and, without limiting the generality
of the foregoing, specifically ratifies and approves all agreements and other
instruments as may have been executed and delivered on behalf of the Company
prior to said date and which are in force and effect on said date.

          6.9. Certain Conditions to Transfer. As a condition precedent to any
Transfer under Section 6.4(a), (b) (other than Section 6.4(b)(iv)) or (c), each
Transferee shall have executed and delivered to the Company and each other
Stockholder, an instrument in substantially the form of Exhibit K hereto
confirming that such Transferee agrees to be bound by the terms of this
Agreement (including, without limitation, this Article VI and Article VII) and
shall have" submitted to the Company such evidence as the Company may reasonably
request to demonstrate that such Transfer is a permitted transfer under this
Article VI. Any Transferee of Common Stock permitted pursuant to the terms of
Section 6.4(a), (b) (other than Section 6.4(b)(iv)) or (c) shall, upon execution
and delivery to the Company and each other Stockholder of an instrument in
substantially the form of Exhibit K hereto, be entitled to all the benefits of
this Agreement, including without limitation, the exchange rights as set forth
in Article V. The certificates issued to any Transferee which represent the
Common Stock so Transferred shall bear the legends provided in Article IX
hereof, if required by such Article.

          6.10. Responsibility for Subscriptions. Any Transferee of all or a
portion of a Stockholder's shares of Common Stock shall be obligated to pay when
due any Called Subscriptions or Available Subscriptions on account of such
transferred shares of Common Stock. Each Stockholder agrees that,
notwithstanding the Transfer of all or any portion of its Common Stock, as
between it and the Company it will remain liable for the Called Subscriptions
and Available


                                      -54-



Subscriptions in each case relating to the Transferred shares of Common Stock.

                                  ARTICLE VII.

                                  SUBSCRIPTIONS

          7.1. Additional Subscriptions. In addition to each Stockholder's
Initial Subscription, subject to Section 7.2 hereof, each Stockholder shall make
additional subscriptions in the amounts and on the dates (the Additional
Subscription Dates") set forth opposite such Stockholder's name on Schedule XVII
hereto. Any subscription payment made by a Stockholder pursuant to this Section
7.1, is sometimes referred to herein as an "Additional Subscription Payment."
Upon payment by a Stockholder of its Additional Subscription Payment, the
Company shall issue to such Stockholder, at a purchase price of $25,000 per
share, the number of additional shares of Common Stock set forth opposite such
Stockholder's name on Schedule XVII hereto. All such additional shares issued to
a holder of Class A Common Stock shall be shares of Class A Common Stock, all
such additional shares issued to a holder of Class B Common Stock shall be
shares of Class B Common Stock and all other such additional shares shall be
shares of Class C Common Stock.

          7.2. Delay or Acceleration of Additional Subscription Payments. (a) On
or before the tenth (10th) business day prior to any Additional Subscription
Date, the Board shall have the authority to postpone one or more of the
Additional Subscription Dates to such date or dates as the Board shall deem in
the best interest of the Company. Upon any such decision by the Board, the
Company shall promptly notify each Stockholder of such postponement and the new
Additional Subscription Date. Notwithstanding anything to the contrary in
Section 7.l or this Section 7.2, the Company shall not have the right to require
Additional Subscription Payments pursuant to this Article VII after the fourth
anniversary of the Closing Date.

          (b) The Board shall also have the right to accelerate Additional
Subscription Payments by delivering to each Stockholder a funding notice (each,
a "Funding Notice") setting forth the amount of such Additional Subscription
Payment and the date on which such Additional Subscription Payment shall be
made. Each Stockholder shall, within fifteen (15) days after the date of a
Funding Notice, pay its Called Subscription to the Company in the amount set
forth in the Funding Notice, and the Company shall issue


                                      -55-



additional shares of Common Stock to such Stockholder to reflect a purchase
price of $25,000 per share, provided that such amount to be paid shall not
exceed such Stockholder's Available Subscription immediately prior to the
issuance of such Funding Notice. Subject to Section 7.4, payments required to be
made by the Stockholders pursuant to a Funding Notice shall be in proportion to
the Stockholders' Proportionate Shares. The Board shall have the right to
deliver a Funding Notice under this Section 7.2 only to fund (1) cash needs for
the Properties Currently Under Development and for the Planned Expansion and
Renovation Programs, (2) liabilities in excess of the Special Reserves therefor
set forth on Schedule XV hereto to the extent not funded with the Initial
Subscriptions and (3) the cost of purchasing a joint venture partner's interest
in any of the properties listed in Schedule VI.

          7.3. Certain Rights and Obligations with Respect to Additional
Subscription Payments. Each Stockholder waives its obligation to any setoff or
reduction with respect to its right to make its Additional Subscription Payments
based on any claim that such Stockholder has against the Company (without
prejudice to such Stockholder's right to assert such claim in a separate
action). The reinvestment or establishment of a reserve by the Company of or
from Operating Cash Flow or Net Disposition Proceeds shall not reduce any
Stockholder's Called Subscriptions or Available Subscription. Except as
expressly required by Section 7.1, 7.2 and 7.4, no Stockholder shall have any
obligation to make any subscription payment to the Company or to advance any
funds thereto.

          7.4. Failure to Make Additional Subscription Payments. If any
Stockholder shall fail to timely make an Additional Subscription Payment
required pursuant to Section 7.1 or 7.2 (such Stockholder is herein referred to
as a "Defaulting Stockholder"), the Company shall first give written notice to
the Defaulting Stockholder offering it 10 additional days in which to make its
Additional Subscription Payments and acquire additional shares of Common Stock,
and if such Defaulting Stockholder shall fail within such 10 day period to make
such Additional Subscription Payments, the Company shall give notice of such
failure to all other Stockholders (each, a "Non-Defaulting Stockholder"), and
such Non-Defaulting Stockholders shall within ten (10) days of such notice
(unless the Defaulting Stockholder shall have made its Additional Subscription
Payment during such period), fund their Proportionate Share (the respective
percentage which the shares owned by each such Non-Defaulting Stockholder bears
to the total number of shares of all Non-Defaulting Stockholders) of the
Additional


                                      -56-



Subscription Payment that the Defaulting Stockholder failed to pay and shall
acquire their Proportionate Share of the additional shares of Common Stock which
the Defaulting Stockholder failed to acquire; provided, however, no Stockholder
shall be required pursuant to this Section 7.4 to make subscription payments in
excess of such Stockholder's Available Subscription and provided, further, that
any payments made by a Non-Defaulting Stockholder pursuant to this Section 7.4
shall be deemed to be Funded Subscriptions of such Stockholder. All shares of
Common Stock owned by a Defaulting Stockholder that are not shares of Class C
Common Stock shall automatically be converted into shares of Class C Common
Stock upon a Stockholders' failure to make an Additional Subscription Payment
pursuant to Section 7.1 or 7.2 and the expiration of the ten (10) day period
referred to above.

          7.5. Funding Shortfalls. If as a result of a default by a Defaulting
Stockholder and after giving effect to Section 7.4 above, the Funded
Subscriptions of all Stockholders is less than the Aggregate Subscriptions of
such Stockholders, then the Board may give notice of such shortfall to all
Non-Defaulting Stockholders, and such Non-Defaulting Stockholders shall within
twenty (20) days of such notice have the right, but not the obligation, to fund
their Proportionate Share of the additional required funding. Each
Non-Defaulting Stockholder who elects to participate shall acquire its adjusted
Proportionate Share (the respective percentage which the shares owned by each
participating Non-Defaulting Stockholder bears to the total number of shares of
all participating Non-Defaulting Stockholders) of the additional shares of
Common Stock represented by such additional funding. All such additional shares
acquired with such additional funding shall be shares of Class C Common Stock
which shall be acquired at a price determined by the Board.

                                  ARTICLE VIII.

                                DISSOLUTION RIGHT

          8.1. Special Dissolution Right. (a) At any time after the Dissolution
Trigger Date, the holders of all shares of Class A Common Stock (acting by
majority vote), on the one hand (the "Class A Group"), and the holders of all
shares of Class B Common Stock (acting by majority vote) (the "Class B Group"),
on the other hand, shall each have the right to offer their Common Stock to the
other Group by delivering a written notice to the Company and the other Group
(by delivery to GGP in the case of the Class A Group


                                      -57-



and to NYSCRF in the case of the Class B Group, provided each still owns shares
of Class A Common Stock or Class B Common Stock, respectively) (the "Dissolution
Commencement Notice"). The Company shall promptly, after receipt thereof,
deliver a copy of any Dissolution Commencement Notice to all Stockholders other
than GGP and NYSCRF. Any action by the Class A Group hereunder shall for all
purposes hereunder bind and be deemed to include all other holders of shares of
Class A Common Stock and all holders of shares of Class C Common Stock. Any
action by the Class B Group hereunder shall for all purposes hereunder bind and
be deemed to include all other holders of shares of Class B Common Stock. The
Group that delivers a Dissolution Commencement Notice shall be referred to as
the "Offeror" and the other party or parties shall be referred to as the
"Offeree." No Group may deliver more than one Dissolution Commencement Notice in
any 18-month period.

          (b) Upon receipt of a Dissolution Commencement Notice, the Offeror and
the Offeree shall cause the Company to obtain an appraisal of the fair market
value of each of the Company's properties as follows. Within ten (10) days of
the Dissolution Commencement Notice, each Group shall each select an Appraiser.
If either Group fails to select an Appraiser within such ten (10) day period,
such Group shall forfeit its right to select an Appraiser. Within ten (10) days
of the selection by each Group of its Appraiser, the selected Appraisers shall
collectively select a third Appraiser. If no third Appraiser is selected within
such time period, the Appraisal Institute shall select the third Appraiser upon
the request of either Group's selected Appraiser. Each of the Appraisers shall
be instructed to complete and submit to the Offeror and Offeree its appraised
valuation in full narrative form within sixty (60) days of the selection of the
third Appraiser. If an Appraiser shall not deliver its appraisal for each
property within such sixty (60) day period, any appraisal subsequently submitted
by such Appraiser shall be disregarded. If, after the Offer Effective Date but
prior to delivery of the Response Notice, the Offeror or the Offeree believes
that a Material Adverse Change has occurred with respect to any Company property
since the date of the foregoing appraisal, the Offeror or the Offeree may, by
notice to the Appraisers, require that the Appraisers issue a new appraisal of
such property reflecting such Material Adverse Change; provided that the
obtaining of a new appraisal shall not extend the date on which a Response
Notice is to be delivered and; provided, further, however, that if such new
appraisal is delivered after the delivery of a Response Notice, the Dissolution
Value of the Company or the Dissolution Value of a Property, as the case may be,
shall be adjusted to account for such


                                      -58-



new appraisal. Such new appraisal shall be conducted in the manner and in
accordance with the rules applicable to the original appraisals. A "Material
Adverse Change" shall mean, with respect to any property, an event or occurrence
that is reasonably likely to have resulted in the diminution by 10% or more of
the appraised value of such property as determined prior to such event or
occurrence. If there shall occur a Material Adverse Change with respect to any
property after delivery of the Response Notice, no additional appraisals shall
be made with respect to such property and the appraised value of such property
shall remain as in effect prior to such Material Adverse Change for all purposes
hereunder. The appraised value for each property shall be the average of the two
closest appraisals for that property. As used herein, "Appraiser" means an
independent member of the Appraisal Institute, with a national practice, having
at least ten years' standing and established experience in appraising companies
similar to the Company.

          (c) Upon receipt of the final appraised value as determined by
subsection (b) above, the Offeror (by majority vote) shall have thirty (30) days
to withdraw, by written notice to the Offeree, the Dissolution Commencement
Notice. In the event of such withdrawal, the Offeror shall pay all costs and
expenses of all Appraisers. If within such thirty (30) day period (the last day
of such thirty (30) day period being the "Offer Effective Date"), the Offeror
shall not have withdrawn the Dissolution Commencement Notice, the Dissolution
Commencement Notice shall become effective and shall constitute an irrevocable
offer (the "Offer") by the Offeror to sell to the Offeree all of its Common
Stock at a purchase price (the "Dissolution Purchase Price") equal to the
Offeror's Proportionate Share of the Dissolution Value of the Company. The
"Dissolution Value of the Company" shall be the book value of the Company as of
the end of the Company's most recent fiscal quarter, calculated in accordance
with GAAP, except that in calculating such book value the aggregate appraised
fair market value of the Company's properties determined in accordance with
paragraph (b) above shall be used in lieu of the GAAP net book value of the
Company's properties. In the event the Offer shall become effective, each Group
shall bear one half of the costs and expenses of all Appraisers.

          (d) Upon effectiveness of the Offer as described in subsection (c)
above, the Offeree shall have the right to either (i) purchase the Offeror's
Common Stock for the Dissolution Purchase Price, (ii) elect to require that the
Company, or all or substantially all of the Company's assets, be sold
(including, without limitation, by way of merger) in which case the Board shall
proceed diligently to


                                      -59-



sell the Company or the Company Assets so that such sale shall be completed
within no longer than a fifteen (15) month period, or (iii) elect to distribute
certain of the Company's properties in the manner described in paragraph (f)
below. The Offeree may exercise such right by written notice to the Offerer,
delivered within six (6) months after the Offer Effective Date, of its election
(each such notice, a "Response Notice"). If the Offeree shall not deliver a
Response Notice within much six (6) month period, the Offeree shall be deemed to
have elected the alternative set forth in clause (iii) above.

          (e) If the Offeree elects to purchase all of the Offeror's Common
Stock pursuant to Section 8.1(d)(i) above, the closing of the purchase and sale
of the Offeror's Common Stock shall take place at the offices of counsel to the.
Offeror and shall occur on the date that is six (6) months after the date of the
Response Notice (or, if such date is not a business day, on the next succeeding
day that is a business day) unless the Offeror and Offeree shall have agreed
upon a different date in writing. At such closing, (i) the Offeror shall deliver
to the Offeree certificates representing the Offeror's Common Stock, free and
clear of any lien, claim or encumbrance (and the Offeror hereby represents,
warrants and covenants that such Common Stock shall, immediately prior to such
sale, be so free and clear), (ii) the Offeree shall deliver to the Offeror the
Dissolution Purchase Price in immediately available funds, and (iii) the Offeror
and the Offeree shall execute such other documents and take such other action as
shall be reasonably necessary to consummate the purchase and sale of the
Offeror's Common Stock as contemplated by this Article VIII. Each member of the
Offeree shall be obligated to purchase the Offeror's Common Stock pro rata in
proportion to such member's respective percentage interest of the Offeree (the
respective percentage which the shares owned by such member bears to the total
number of shares of all Stockholders comprising the Offeree) and each member of
a Group which is the Offeror shall be obligated to sell all of its shares in the
Company. If the Offeree includes holders of Class A Common Stock, the election
referred to above may be made by a majority of the holders of Class A Common
Stock; provided, however, that if the holder of Class A Common Stock elects
option (i) above, only the holders of Class C Common Stock who have approved
such election shall be obligated to purchase the Offeror's Common Stock and the
Offeree, for purposes of Section 8.1(e), shall be deemed to include only the
holders of Class A Common Stock and the holders of Class C Common Stock who have
approved such election. After the date of the Response Notice until the closing
of the purchase by the Offeree pursuant to this


                                      -60-



Section 8.1(e), the Offeror shall retain all rights with respect to its Common
Stock, including without limitation the right to vote for directors or to
receive dividends or other distributions paid or made with respect to such
Common Stock.

          If the Offeree elects to purchase all of the Offeror's Common Stock
pursuant to Section 8.1(d)(i) and such purchase is subject to the premerger
notification and reporting requirements under HSR and the Rules, then (i) the
Offeror and the Offeree shall use their respective reasonable best efforts to
duly file with the FTC and the Assistant Attorney General, no later than the
tenth (10th) day after the date of the Response Notice, fully completed
premerger notification and report forms with respect to the Offeror and the
Offeree pursuant to Section 7A(a) of HSR and (ii) the Offeror shall use its
reasonable best efforts to file with the FTC and the Assistant Attorney General
no later than the tenth (10th) day after the date of the Response Notice a fully
completed written request for early termination of the waiting period pursuant
to Section 7A(b)(2) of HSR and Rule 803.11 thereunder, and cause the applicable
waiting period under HSR to terminate on or before the ninetieth (90th) day
after the date of the Response Notice. The filing fees incurred in connection
with the premerger notification and report forms shall be borne by the Offeror.

          If the Offeror and the Offeree have complied with the provisions of
the immediately preceding paragraph but the applicable waiting period under HSR
with respect to purchase of the Offeror's Common Stock has not terminated by the
closing date set forth in this Section 8.1(e), then, notwithstanding anything to
the contrary in this Section 8.1(e), the closing date shall be extended to the
fifth business day after all applicable waiting periods under HSR have been
terminated. From and after the original closing date set forth in this Section
8.1(e), the Offeror shall continue to use its reasonable beet efforts to cause
the applicable waiting period under HSR to be terminated.

          If the Offeree shall default in its obligation to purchase the
Offeror's Common Stock as provided in this Section 8.1(e), then the Company
shall make the property distribution in the manner described in clause (f) below
(but in a single distribution and with the Offeror entitled to select all of the
properties until it has selected properties equal in value to its Proportionate
Share of the Dissolution Value of all of the Company's properties (calculated
pursuant to paragraph (f) hereof)) as soon as possible following such default,
but in no event later than


                                      -61-



thirty (30) days after the date scheduled for closing the purchase of the
Offeror's Common Stock under Section 8.1(e), and the Offeror shall have the
right without the approval of any other Stockholders to cause the Company to
make such distribution of properties and to take all such actions as may be
necessary to accomplish such distribution.

          (f) If the Offeree elects to distribute certain of the Company's
properties (together with associated liabilities) pursuant to Section
8.1(d)(iii) above or a distribution is required to be made pursuant to Section
8.1(e) or 8.1(g), the Company's properties (together with associated
liabilities) shall be divided among the Offeror and the Offeree by having each
select properties on an alternating one-by-one basis (with the Offeree being
entitled to the first selection) until either the Offeror or the Offeree has
selected properties having a Dissolution Value equal to its Proportionate Share
of the Dissolution Value of all of the Company's properties with any remaining
properties going to the other party. The "Dissolution Value of a Property" shall
be the appraised fair market value of the property, determined in accordance
with subsection (b) above, less the face amount of all indebtedness encumbering
or incurred with respect to the property, and the amount of any other
liabilities existing with respect to such property (including any unpaid
arrearages in the payment of debt service with respect to the property)
calculated in accordance with GAAP and reflected on the Company's financial
statements for the most recent fiscal quarter. All properties selected by the
Offeror (together with associated liabilities) will be distributed to the
Offeror in exchange for all of its shares of Common Stock, and the Offeror shall
thereafter no longer be a Stockholder of the Company unless GGP or any of its
affiliates is a member of the Offeror in which case all properties selected by
the Offeree (together with associated liabilities) will be distributed to the
Offeree in exchange for all of its shares of Common Stock, and the Offeree shall
thereafter no longer be a Stockholder of the Company. The party to whom the
properties shall be distributed shall be referred to as the "Distributee". The
Offeror and the Offeree will bear in equal portions all transfer costs
(including, without limitation, any transfer taxes, if any are required by law,
New York State real property gains taxes, if any are required by law, title
insurance premiums, costs of surveys and recording fees) and any prepayment
penalties or other amounts payable to lenders, and the Company's Cash Reserves
(as reflected in the Company's financial statements as of the end of the
Company's most recent fiscal quarter) associated with the distribution of such
properties and other corporate level assets and liabilities shall be


                                      -62-



apportioned on a pro rata basis. The Distributee shall indemnify the Company and
the Stockholders against any losses, claims, damage or liabilities to which any
of them may become subject arising out of or relating to the properties (and
associated liabilities) distributed to the Distributee. The Company and the
Stockholders shall indemnify the Distributee against any losses, claims, damage
or liabilities to which the Distributee may become subject arising out of or
relating to the properties (and associated liabilities) retained by the Company.
The properties distributed to the Distributee shall be distributed subject to
customary prorations. Each of the Offeree and Offeror will cooperate with the
other to facilitate the distribution of properties contemplated by this Section
8.1(f), including, without limitation, with respect to obtaining (1) tenant
estoppels or delivering notices to tenants relating to the distribution, and (2)
tenant, lender, ground lessor or joint venturer consents and to eliminate any
cross-collateralized or cross-defaulted financings between the properties
selected by the Distributee, on the one hand, and the other properties, on the
other hand, including, without limitation, by agreeing to encumber properties
not designated for transfer and to remove cross-collateralized encumbrances from
properties designated for transfer. The distribution of properties (together
with associated liabilities) will occur as early as possible in three
installments of as near equivalent value as possible over three taxable years,
with the first distribution to occur as early as possible in the taxable year in
which the Response Notice is given and thereafter a distribution shall occur on
the first business day of each of the two subsequent tax years. For example, if
the Offeror delivers a Dissolution Commencement Notice on December 1, 1999 and
the Offeree delivers a Response Notice electing to distribute properties
pursuant to Section 8.1(d)(iii) above on May, 31, 2000, the first distribution
would occur on June 1, 2000, the second distribution would occur in January,
2001, and the third distribution would occur in January, 2002. Upon the second
distribution of properties, all Common Stock owned by the Distributee shall
automatically be converted into Class C Common Stock and such party shall no
longer have the right to elect directors to the Board unless the Company shall
fail to make the third distribution as required by this Section 8.1(f) in which
case such Common Stock shall automatically be converted back to its original
Class of Common Stock. During the distribution period, (i) the Offeror may cause
the Company to engage a property manager or managers to manage the properties
selected by the Offeror rather than have such properties be managed by the
Company or its managers, (ii) the Company shall encumber any of the properties
selected by the Offeror in connection with a


                                      -63-



financing or refinancing only at the direction of the Offeror and (iii) the
Company shall operate the properties selected by the Offeror to the extent owned
by the Company in a manner consistent with past business practices. During the
distribution period, the risk of casualty, damage or condemnation or other
adverse change with respect to any property to be distributed to the Distributee
shall be borne by the Distributee and with respect to any property to be
retained by the Company shall be borne by the Company, provided, however, that
any insurance proceeds payable with respect thereto shall, with respect to a
property to be distributed to the Distributee, be paid to the Distributee, and
with respect to a property to be retained by the Company, be paid to the
Company. If as a result of the selection process described above, one party
shall be entitled to properties that have an aggregate Dissolution Value (based
on the Dissolution Value of the Properties obtained pursuant to this paragraph
(f)) in excess of such party's Proportionate Share of the Dissolution Value of
all of the Company's properties (including the pro-rations and adjustments
described in this paragraph (f)), then such party shall pay a cash adjustment to
the other party. Such cash adjustment shall be paid in three equal installments
on each date a distribution of properties is made.

          If at the time a distribution of properties is to be made a property
(an "Impaired Property") cannot be distributed due to an inability to remove it
from a cross-collateralized or cross-defaulted pool, a title issue, the
inability to obtain a necessary consent or any other similar matter, then such
property shall be retained by the Company and the Offeror and Offeree shall
reselect the properties that remain in the Company and that were selected after
the Impaired Property was selected, on an alternating one-by-one basis until
either the Distributee has selected properties able to be distributed as
contemplated herein having a Dissolution Value equal to its then Proportionate
Share of the Dissolution Value of all of the Company's properties.

          (g) If pursuant to Section 8.1(d)(ii), the Offeree elects to require
that the Company, or all or substantially all of the Company's assets, be sold
(including by way of merger), but such sale or merger has not been completed
within the fifteen (15) month period following the Response Notice, then the
Company shall make the property distributions in the manner described in clause
(f) above (but in a single distribution and with the Offeror entitled to select
the first property) as soon as possible following the expiration of such fifteen
(15) month period.


                                      -64-



          (h) Notwithstanding anything to the contrary in Article V, (i) if the
Class B Group is the Offeror, then from and after the delivery of a Dissolution
Commencement Notice by the Class B Group, the Class B Group shall not have the
right to exchange their Common Stock pursuant to Article V unless the Class B
Group has withdrawn such Dissolution Commencement Notice pursuant to Section
8.1(c) above and (ii) if the Class A Group is the Offeror and the Class A Group
has not withdrawn its Dissolution Commencement Notice pursuant to Section 8.1(c)
above, then from and after the delivery by the Class B Group of a Response
Notice pursuant to Section 8.1(d) above, the Class B Group shall not have the
right to exchange their Common Stock pursuant to Article V. If the Class A Group
has delivered a Dissolution Commencement Notice and a holder of Class B Common
Stock delivers an Exchange Election Notice prior to the delivery by the Class B
Group of a Response Notice, then (1) such Exchange Election Notice shall
override such Dissolution Commencement Notice with respect to the shares of
Class B Common Stock that are the subject of such Exchange Election Notice, (2)
the shares of Class B Common Stock that are the subject of such Exchange
Election Notice shall be deemed to be shares of Class C Common Stock owned by
GGP for all purposes of this Section 8.1 whether or not the closing in respect
of such Exchange Election Notice has occurred prior to the delivery by the Class
B Group of a Response Notice and (3) the Class B Group shall not have the right
to elect in its Response Notice to purchase the Class A Group's Common Stock for
the Dissolution Purchase Price pursuant to Section 8.1(d)(i) above. Nothing in
this Article VIII shall affect any Class C Stockholder's right to exchange its
Common Stock pursuant to Article V.

          8.2. Other Dissolutions. (a) Notwithstanding anything in this
Agreement to the contrary, the holders of the Class A Common Stock or the
holders of the Class B Common Stock shall be entitled to elect to dissolve the
Company (in which case the Board shall promptly cause the Company to be
dissolved) in the event the Homart Closing Date and the closings under the
Natick Mall Agreement, the Management Transfer Agreement, the financing
contemplated under the Financing Commitment and the Existing Lender Arrangements
shall not have been consummated and shall not have closed by January 31, 1996.

          (b) If at any time shares of either Class A Common Stock or Class B
Common Stock (but not both) shall be outstanding, any determination to dissolve
the Company and the manner in which such dissolution shall occur shall be
determined by the Board and submitted to a vote of the Electing Class in
accordance with the provisions of the GCL.


                                      -65-



If at any time shares of neither the Class A Common Stock or Class B Common
Stock shall be outstanding, any determination to dissolve the Company shall be
made by the Stockholders in accordance with the Company's Certificate of
Incorporation and the GCL.

                                   ARTICLE IX.

                                     LEGENDS

          All Stockholders agree that any certificates evidencing Common Stock
subject to this Agreement shall be stamped or endorsed with a legend in
substantially the following form; provided, however, in the event that shares of
Common Stock are registered under the 33 Act, the Company shall promptly upon
request, but in any event not later than is necessary in order to consummate any
sale pursuant to any underwriting agreement or sales agency agreement relating
thereto, deliver a replacement certificate not containing the first paragraph of
the legend below in exchange for the legended certificate (it being understood
that such legend shall be placed on such replacement certificate if the sale
does not occur in accordance with the terms of the registration statement); and
provided, further, the Company shall upon termination of this Agreement promptly
upon request deliver a replacement certificate not containing the second
paragraph of the legend below in exchange for the legended certificate:

          THE SHARES OF COMMON STOCK REPRESENTED BY THIS CERTIFICATE HAVE NOT
BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR APPLICABLE
STATE SECURITIES LAWS, AND ACCORDINGLY NEITHER THE SHARES NOR ANY INTEREST
THEREIN MAY BE SOLD, TRANSFERRED, PLEDGED, OR OTHERWISE DISPOSED OF IN THE
ABSENCE OF SUCH REGISTRATION OR AN EXEMPTION THEREFROM UNDER SAID ACT AND ANY
SUCH LAWS APPLICABLE THERETO AND THE RULES AND REGULATIONS THEREUNDER.

          IN ADDITION, TRANSFERS, VOTING AND OTHER MATTERS IN RESPECT OF THE
SHARES OF COMMON STOCK REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO A
SHAREHOLDERS AGREEMENT DATED AS OF DECEMBER 20, 1995 AMONG THE COMPANY AND
CERTAIN STOCKHOLDERS NAMED THEREIN, AS AMENDED FROM TIME TO TIME, A COPY OF
WHICH AGREEMENT IS ON FILE AT THE PRINCIPAL OFFICE OF THE COMPANY AND MAY BE
OBTAINED WITHOUT CHARGE UPON WRITTEN REQUEST TO THE COMPANY.

          THE SHARES OF COMMON STOCK REPRESENTED BY THIS CERTIFICATE ARE SUBJECT

MAINTENANCE OF ITS


                                      -66-



STATUS AS A REAL ESTATE INVESTMENT TRUST UNDER THE INTERNAL REVENUE CODE OF
1986, AS AMENDED (THE "CODE"). NO INDIVIDUAL MAY BENEFICIALLY OWN COMMON SHARES
IN EXCESS OF THE THEN APPLICABLE OWNERSHIP LIMIT WITH RESPECT TO COMMON SHARES,
WHICH MAY DECREASE OR INCREASE FROM TIME TO TIME, UNLESS SUCH INDIVIDUAL IS AN
EXISTING HOLDER. ANY INDIVIDUAL WHO ATTEMPTS TO BENEFICIALLY OWN SHARES IN
EXCESS OF THE ABOVE LIMITATION MUST IMMEDIATELY NOTIFY THE COMPANY. IN ADDITION,
NO PERSON MAY CONSTRUCTIVELY OWN COMMON SHARES IN EXCESS OF THE CONSTRUCTIVE
OWNERSHIP LIMIT, UNLESS SUCH PERSON IS AN EXISTING CONSTRUCTIVE HOLDER. ANY
PERSON WHO ATTEMPTS TO CONSTRUCTIVELY OWN COMMON SHARES IN EXCESS OF THE
CONSTRUCTIVE OWNERSHIP LIMIT MUST IMMEDIATELY NOTIFY THE COMPANY. ALL
CAPITALIZED TERMS USED IN THIS LEGEND HAVE THE MEANINGS DEFINED IN THE COMPANY'S
CERTIFICATE OF INCORPORATION, AS THE SAME MAY BE FURTHER AMENDED FROM TIME TO
TIME, A COPY OF WHICH, INCLUDING THE RESTRICTIONS ON OWNERSHIP AND TRANSFER,
WILL BE SENT WITHOUT CHARGE TO EACH STOCKHOLDER WHO SO REQUESTS. IF THE
RESTRICTIONS ON OWNERSHIP AND TRANSFER ARE VIOLATED, THE COMMON SHARES
REPRESENTED HEREBY WILL BE AUTOMATICALLY EXCHANGED FOR EXCESS SHARES AND WILL BE
DEEMED TRANSFERRED TO A SPECIAL TRUST AS PROVIDED IN THE CERTIFICATE OF
INCORPORATION.

                                   ARTICLE X.

                            POST-CLOSING TERMINATION

          Following the Closing, this Agreement shall terminate upon the earlier
to occur of the following: (i) such time as only one Stockholder or one
Affiliated group of Stockholders owns all of the issued and outstanding Common
Stock and (ii) the affirmative election of a majority of the outstanding shares
of each Class of Common Stock; provided, however, that no such termination shall
relieve any Person of any liability for a prior breach or default. Upon the
termination of this Agreement, (i) all shares of Common Stock shall be entitled
to equal rights in all respects including, without limitation, the election of
directors, (ii) the provisions of the Company's certificate of incorporation and
by laws shall govern, and (iii) the prohibitions on Transfers of Common Stock
contained in Sections 6.2, 6.4 and 6.5(a) and (d) shall, notwithstanding such
termination, continue to apply.


                                      -67-



                                   ARTICLE XI.

                                  MISCELLANEOUS

          11.1. Recapitalization, Exchanges, etc. Affecting the Common Stock.
The provisions of this Agreement shall apply to the full extent set forth herein
with respect to (a) the Common Stock and (b) any and all shares of capital stock
of the Company or any successor or assign of the Company (whether by merger,
consolidation, sale of assets or otherwise) which may be issued in respect of,
in exchange for, or in substitution for the Common Stock, by reason of any stock
dividend, split, reverse split, combination, recapitalization, reclassification,
merger, consolidation or otherwise. In the event of any change in the
capitalization of the Company, as a result of any stock split, stock dividend or
stock combination, the provisions of this Agreement shall be appropriately
adjusted.

          11.2. Injunctive Relief. Each party hereto acknowledges that it would
be impossible to determine the amount of damages that would result from any
breach of any of the provisions of this Agreement and that the remedy at law for
any breach, or threatened breach, of any of such provisions would likely be
inadequate and, accordingly, agrees that each other party shall, in addition to
any other rights or remedies which it may have, be entitled to seek such
equitable and injunctive relief as may be available from any court of competent
jurisdiction to compel specific performance of, or restrain any party from
violating, any of such provisions. In connection with any action or proceeding
for injunctive relief, each party hereto hereby waives the claim or defense that
a remedy at law alone is adequate and agrees, to the maximum extent permitted by
law, to have each provision of this Agreement specifically enforced against it,
without the necessity of posting bond or other security against it, and consents
to the entry of injunctive relief against it enjoining or restraining any breach
or threatened breach of such provisions of this Agreement.

          11.3. Successors and Assigns. All the terms and provisions of this
Agreement shall be binding upon, shall inure solely to the benefit of and shall
be enforceable by the parties hereto and their respective successors and
assigns, and no such term or provision is for the benefit of, or intended to
create any obligations to, any other Person, provided that (i) the Company shall
not have either the right or the power to assign or delegate any right or
obligation hereunder (including, without limitation by merger, consolidation or
other operation of law) and any


                                      -68-



purported such assignment or delegation shall be void except as expressly
provided herein, and (ii) no Stockholder may assign any rights under this
Agreement (including, without limitation, by merger, consolidation or other
operation of law) except that, subject to the following sentence, any
Stockholder may assign its rights hereunder, in whole but not in part, in
connection with a Transfer of Common Stock made in strict compliance with all of
the provisions of this Agreement. If any Stockholder shall acquire additional
Common Stock and if any Transferee of any Stockholder shall acquire any Common
Stock, in each case in any manner, whether by a permitted Transfer, operation of
law or otherwise, such Common Stock shall be held subject to all of the terms of
this Agreement, and by taking and holding such Common Stock such Person shall be
conclusively deemed to have agreed to be bound by and to comply with all of the
terms and provisions of this Agreement.

          11.4. Amendment; Waiver. (a) Neither this Agreement nor any provision
hereof nor any provision of the Company's Certificate of Incorporation may be
changed, waived, discharged or terminated orally, but only by an instrument in
writing signed by the Company and by the holders of a majority of the shares of
each class of Common Stock.

          (b) No failure by any party to insist upon the strict performance of
any covenant, duty, agreement or condition of this Agreement or to exercise any
right or remedy consequent upon breach thereof shall constitute a waiver of any
such breach or of any other covenant, duty, agreement or condition, any such
waiver being effective only if contained in a writing executed by the waiving
party.

          11.5. Representations by Stockholders. (a) Each Stockholder represents
and warrants, that (i) it has been duly authorized and otherwise duly qualified
to purchase and hold its Common Stock and to execute and deliver this Agreement
and all other instruments executed and delivered on behalf of it in connection
with the acquisition of its Common Stock, (ii) the consummation of such
transactions will not result in a breach or violation of, or a default under,
its charter or by-laws, if such Stockholder is a corporation, or its certificate
of limited partnership or its partnership agreement, if such Stockholder is a
partnership, or its other organizational documents, if such Stockholder is
neither a corporation or partnership, or any existing agreement by which it or
any of its properties is bound and (iii) this Agreement is a binding agreement
on the part of such Stockholder enforceable in accordance with its terms against
such Stockholder.


                                      -69-



          (b) Each Stockholder, by executing this Agreement, represents and
warrants that it has acquired its Common Stock for its own account, or for the

discretion, for investment and not with a view to resale or distribution
thereof, that it has such knowledge and experience in financial and business
matters as to be capable of evaluating the merits and risk of an investment in
the Common Stock, and is able to bear the economic risk of its investment and
that it is fully aware that the Company is relying upon the truth and accuracy
of this representation and warranty. Each Stockholder agrees that it will not
transfer, sell or dispose of all or any portion of, or offer to transfer, sell
or dispose of all or any portion of its Common Stock, or solicit offers to buy
from or otherwise approach or negotiate in respect thereof with any person or
persons whomsoever, all or any portion of its Common Stock in any manner which
could violate or cause the Company to violate applicable federal or state
securities laws.

          (c) Each of GGP and GG Properties represents and warrants to the other
Stockholders (i) that they have delivered or caused to be delivered to each of
the other Stockholders true, correct and complete copies of the Homart Stock
Purchase Agreement (including the side letter agreements relating thereto dated

relating to the purchase of the assets of Homart by the Company have been
entered into by any of the Company, GGP or GG Properties.

          (d) NYSCRF represents and warrants to the Company and the other
Stockholders that it is a "government plan" within the meaning of Section 414(d)
of the Code and Section 3(32) of ERISA and that its acquisition of Common Stock

          (e) NYSCRF represents and warrants to the other Stockholders that it
is exempt from the filing requirements


                                      -70-



of HSR and the Rules. GGP represents and warrants to the other Stockholders that

is not a prohibited transaction under Section 406 of ERISA or Section 4975 of
the Code, except to the extent such acquisition and holding of Common Stock
meets the requirements of a prohibited transaction class exemption.

          11.6. Notices. Except as otherwise provided in this Agreement, all
notices, requests, claims, demands, waivers and other communications hereunder

          11.8. Confidentiality. The Company and each of the Stockholders agree

with the operation of its business) of any of the terms of this


                                      -71-

and freedom of information laws) or (e) to any lender or prospective lender to,
or investor in, such Stockholder.

          In the event that a Stockholder shall receive a request (or, in the
case of NYSCRF, at such time a notice of such request is communicated to the
representatives of NYSCRF who are responsible for the administration of its
ownership of Common Stock) to disclose any of the terms of this Agreement under
subpoena or order, such Stockholder shall (i) promptly notify the Board thereof,
(ii) consult with the Board on the advisability of taking steps to resist or

Exhibits hereto) constitutes the entire agreement between the parties hereto and


                                      -72-

3, 1995.

          11.13. Severability. Any provision of this Agreement that is
prohibited, unenforceable or not authorized in any jurisdiction shall, as to
such jurisdiction, be ineffective to the extent of such prohibition,
unenforceability or lack of authorization without invalidating the remaining
provisions hereof or affecting the validity, unenforceability or legality of
such provision in any other jurisdiction.

          11.14. Counterparts. This Agreement may be executed in two or more
counterparts, each of which shall be deemed an original, but all of which
together constitute one and the same instrument.

          11.15. Arbitration. Any claim arising out of an alleged breach of this
Agreement and any claim that Cause exists pursuant to Section 3.6(c) shall be
resolved by arbitration. Such arbitration shall be conducted in accordance with
the following:

          (a) Each party shall have five (5) business days after written notice
by another party of the commencement of arbitration proceedings hereunder to
appoint an arbitrator who is on the approved panel of arbitrators of the
American Arbitration Association. Each party shall immediately notify the other
party of such appointment. The two arbitrators so appointed shall then select a
third arbitrator within five (5) business days after the appointment of the
second arbitrator to then constitute the Board of Arbitration. If any party
shall fail to appoint an arbitrator within such five (5) business day period, or
if the two arbitrators selected by the parties shall fail, within five (5)
business days of their selection, to make a selection of a third arbitrator,
then the American Arbitration Association shall appoint the arbitrator that was
not selected by the failing party or shall appoint the third arbitrator, as the
case may be, in accordance with the Commercial Arbitration Rules of the American
Arbitration Association. The Board of Arbitration shall then proceed under such
rules.

          (b) Following the designation of such Board of Arbitration, the
parties, together with the members of the Board of Arbitrators, shall promptly
undertake appropriate


                                      -73-



informal efforts to mediate and negotiate a solution to the matter covered by
the original notice.

          (c) If a negotiated solution cannot be achieved within fourteen (14)
days after the date on which the Board of Arbitration is constituted, then the
Board of Arbitration shall notify the parties. The proceeding, upon such
notification, will then become a compulsory arbitration to be conducted under
the Commercial Arbitration Rules of the American Arbitration Association by the
Board of Arbitration. These rules shall be subject to the following
modifications:

          (i) discovery shall be permitted under the same standards provided for
     in the Federal Rules of Civil Procedure;

          (ii) the members of the Board of Arbitration shall interpret and apply
     the provisions of this Agreement;

          (iii) except as otherwise set forth in Section 3.6(e), the arbitration
     costs may be charged to the losing party or allocated between the parties
     as may be determined by the Board of Arbitration; and

          (iv) the proceedings will be held in Chicago, Illinois, unless the
     parties shall otherwise agree in writing.

          (d) In connection with the enforcement of the mediation and
arbitration provisions of this Section 11.15, any agreement, decision or award
shall be final and conclusive as to any such claim.

          11.16. Consent to Jurisdiction. In connection with any suit, claim,
action or proceeding relating to the rights and obligations of the parties
arising out of this Agreement: GG Properties, GGP and each other Stockholder
hereby consents to the in personam jurisdiction of the United States federal
courts and Delaware state courts located in New Castle County, Delaware; each
such Person agrees that service in the manner set forth in Section 11.6 hereof
shall be valid and sufficient for all purposes; and each such Person agrees to,
and irrevocably waives any objection based on forum non conveniens or venue not
to, appear in any United States federal court or Delaware state court located in
New Castle County, Delaware. Each Stockholder (other than GGP) hereby
irrevocably appoints the


                                      -74-



Company as agent for service of process with respect to any matters relating to
the rights and obligations of the parties arising out of this Agreement.


                                      -75-



          IN WITNESS WHEREOF, the undersigned have executed this Agreement as of
