Item 2.   Acquisition or Disposition of Assets.
          -------------------------------------

          On May 8, 1998, two Delaware limited liability companies, the sole
members of which are GGP Limited Partnership, a Delaware limited partnership
(the "Partnership"), and a wholly-owned subsidiary of the registrant, General
Growth Properties, Inc., a Delaware corporation (the "Company"), which is the
general partner of and owner of an approximately 65.2% interest in the
Partnership, acquired from Grosvenor International (Westcoast Estates) Limited,
a California corporation, and P.I.C. Investments, a Nevada corporation, in a
negotiated arms-length transaction 100% of the partnership interests in the 
partnership which owns Northbrook Court, an enclosed mall shopping
center located in Northbrook (Chicago), Illinois. The purchase price for the 
partnership interests was paid in cash from borrowings under the Company's line 
of credit. 

          Northbrook Court opened in 1976 and was renovated and expanded in 1995
and 1996.  It is a two-level mall of approximately one million square feet.  The
center is anchored by Neiman Marcus, Lord & Taylor, Marshall Field's and a 14-
screen, state-of-the-art General Cinema theater.  The center has an additional
362,000 square feet of mall shop space, is currently 88% occupied and produces
sales of approximately $333 per square foot.

          On April 3, 1998, two Delaware limited liability companies, the sole
members of which are the Partnership and the Company, acquired from Southwest
Properties Venture, a Colorado joint venture, in a negotiated arms-length
transaction 100% of Southwest Plaza, an enclosed mall shopping center located in
Denver, Colorado. The purchase price consisted of cash from borrowings under the
Company's line of credit, redeemable units of limited partnership interest in
the Partnership and the assumption of certain indebtedness.

          Southwest Plaza opened in 1983 and was renovated in 1994 and 1995. It
is a two-level mall of approximately 1.3 million square feet located on a 102-
acre tract. The center is anchored by Joslin's, Foley's, Sears, JC Penney and
Montgomery Ward. The mall has an additional 438,000 square feet of mall shop
space, a 100,000 square foot freestanding Target store and two office buildings
totaling approximately 92,000 square feet. The center is currently 83% occupied
and produces sales of approximately $265 per square foot.

          The aggregate purchase price paid for Northbrook Court and Southwest
Plaza was approximately $261 million. The acquisition of Northbrook Court, when
taken together with the unrelated acquisition of Southwest Plaza, is deemed to
constitute the acquisition of a significant amount of assets under rules and
regulations promulgated by the Securities and Exchange Commission and therefore
is required to be reported on this Current Report on Form 8-K.

Item 5.   Other Events.
          -------------

          On April 17, 1998, the Company entered into a definitive agreement to
acquire the U.S. retail property portfolio of MEPC plc (the "MEPC Portfolio"), a
United Kingdom based real estate company ("MEPC").  Through the purchase of the
stock of the three U.S. subsidiaries of MEPC that directly or indirectly own the
MEPC Portfolio (the "MEPC U.S. Subsidiaries"), the Company will acquire for
approximately $871 million in cash (less certain adjustments) 100% of eight
enclosed mall shopping centers comprising approximately 7.7 million square fee
of GLA and located throughout the United States.  The stock of the MEPC U.S.
Subsidiaries will be acquired by a newly formed corporate subsidiary of the
Company that will elect to be taxed as a REIT.  This transaction is expected to
close during the second quarter of 1998.

          On May 14, 1998, the Company entered into a definitive merger
agreement to acquire U.S. Prime Property, Inc. (""USPPI"), a private REIT, which
owns (or as of closing will own) 100% of six enclosed mall shopping centers (and
office buildings adjacent to one of the malls) (the "USPPI Portfolio").  The
Company has agreed to acquire USPPI through the merger of a subsidiary owned by
the Company with and into USPPI, for an aggregate purchase price of
approximately $625 million (less certain adjustments), which purchase price
includes approximately $65 million of mortgage indebtedness being assumed.  The
Company expects to complete the acquisition of the USPPI Portfolio together with
an approximately 50% joint venture partner.  This transaction is expected to
close during the second quarter of 1998.

Interests ("Purchase Price") shall be One Hundred Forty-Eight Million Dollars
($148,000,000), as adjusted by the following:

                                       4

          (a) The subtraction of the sum of Three Million Five Hundred Thousand
Dollars ($3,500,000) pursuant to the I. Magnin/GCC Adjustment, as provided in
Section 2.3(h).

          (b) The addition of the aggregate amount of the book value of cash and

calculated as of the Close of Escrow based on the Partners' good faith estimate
thereof, subject to a final adjustment to be made as of 12:00 midnight, May 8,
1998.  The parties shall attempt to fix the day of Close of Escrow to correspond
with the end of an accounting month or other convenient accounting date to
facilitate ease of such accounting adjustments.  Such final adjustment shall be
determined from a Closing Balance Sheet prepared as provided below which Closing
Balance Sheet shall be approved by Buyers, which approval shall not be
unreasonably withheld.  It is intended that the final adjustments to the
Purchase Price based on the adjustments provided in this subparagraph (d) shall
be made within sixty (60) days after the date of the Close of Escrow or as soon
as such adjustments can reasonably be calculated.

          (f) As soon as practicable after the Close of Escrow, the Partners
shall without charge prepare an audited Closing Balance Sheet of the
Partnership.  Such Closing Balance Sheet for the Partnership shall be prepared
in accordance with the prior practices and standards utilized by the
Partnership's accountants in the preparation of audited statements for the
Partnership.  The final adjustments pursuant to this paragraph will be based on
the Closing Balance Sheets and, when delivered by the Partners, will be true and
correct in all substantial and material respects and will be certified by the
Partners to be true and correct to the best of their knowledge.

additional deposit of One Million Four Hundred Eighty Thousand Dollars
($1,480,000).  The initial deposit, the additional deposit and all interest
accrued thereon are hereinafter referred to as the "Deposit".  The Deposit shall
be paid into an interest-bearing account, which interest shall accrue for the
benefit of Buyer up to and including the close of escrow (as hereinafter
defined, the "Close of Escrow") and on the Close of Escrow, the Deposit plus
interest accrued thereon shall be credited against the Purchase Price.  If this
Agreement is terminated by Buyer in accordance with its terms, Buyer shall be

OBLIGATIONS UNDER THIS AGREEMENT AND SUCH DEFAULT IS NOT CURED WITHIN TEN (10)
DAYS AFTER WRITTEN NOTICE THEREOF FROM THE PARTNERS TO BUYER, AND THE PARTNERS
ARE NOT IN DEFAULT, THE PARTNERS SHALL HAVE THE RIGHT TO RETAIN THE DEPOSIT PLUS

DETERMINE WHAT THE PARTNERS' DAMAGES WOULD BE IN THE EVENT OF A DEFAULT BY
BUYER.  THE PARTNERS AND BUYER HAVE BEEN UNABLE TO ARRIVE AT ANY MEANINGFUL
FORMULA OR MEASURE OF DAMAGES FOR BUYER'S DEFAULT AND HAVE THEREFORE AGREED THAT
SUCH DAMAGES WOULD BE EXTREMELY DIFFICULT AND IMPRACTICAL TO DETERMINE IN THE
EVENT OF BUYER'S DEFAULT.  THE DEPOSIT SHALL BE LIQUIDATED DAMAGES AND SHALL BE
THE PARTNERS' SOLE RIGHT TO DAMAGES AND THE PARTNERS WAIVE ALL RIGHT TO SPECIFIC

their respective obligations under this Agreement and such default is not cured
within ten (10) days after written notice thereof from Buyer to the Partners,
and Buyer is not in default, then at Buyer's sole and exclusive option either
(i) upon notice to Escrow Holder the Deposit shall be immediately returned to
Buyer and thereupon this Agreement shall terminate and this Agreement shall be
of no further force or effect, or (ii) Buyer shall have the right to pursue an
action for specific performance of the terms of this Agreement.

          (b) The balance of the Purchase Price, plus or minus prorations, shall
be deposited together with Buyer's portion of the closing costs and

shall take place at the offices of Buyer's counsel, Neal Gerber & Eisenberg, Two
North LaSalle Street, 21st Floor, Chicago, Illinois, 60602, Attn: Reuben C.
Warshawsky.

          2.2  Closing.  The closing of the Escrow (the "Closing" or the "Close
               -------                                                         
of Escrow") shall occur on May 8, 1998 (the "Closing Date") or such other date
as the parties shall mutually agree.

          2.3  The Close of Escrow shall be in accordance with the following
terms, conditions and restrictions:

               (a) Escrow Authorization and Commitment of Parties. A fully-
                   ----------------------------------------------        
executed copy of this Agreement shall be deposited with Escrow Holder as escrow
instructions within ten (10) days of the date hereof. Amended and/or additional
instructions ("Additional Escrow Instructions") not inconsistent with the terms
and conditions of this Agreement may be received into Escrow from Buyer and the
Partners. Escrow Holder is hereby authorized and instructed to deliver the
documents and moneys to be deposited into Escrow as hereinafter provided, with
the terms and conditions contained herein to apply to the Escrow. The Partners
and Buyer shall, prior to Close of Escrow, execute any and all documents and
perform any and all acts reasonably necessary or appropriate to close the
transactions pursuant to the terms of this Agreement.

               (b) Documents to be Deposited with Escrow Holder by the Partners.
                   ------------------------------------------------------------
On or before the Close of Escrow, the Partners shall deposit into Escrow for
delivery to Buyer upon the close hereof (the "Partners' Closing Documents"):

                                       7

Partnership Interests") in the form attached hereto as Exhibit "G" assigning to
NCI all of PIC's Partnership interest in the Partnership;

          (ii)   An instrument of assignment (the "Assignment of Grosvenor's
Partnership Interest") in the form attached hereto as Exhibit "H" assigning to
NCII all of Grosvenor's Partnership interest in the Partnership;

Estoppel Certificate"), in the form attached hereto as Exhibit "I", dated on or
after March 1, 1998 executed by each tenant of space within the Property
(excluding Anchors).  The form of estoppel certificate shall be modified to
complete the relevant information for the respective lease and may be modified
by or for the respective tenants to delete or modify provisions which such
tenants reasonably assert are not required by the estoppel certificate under
their respective leases (such deletions or modifications to be subject to
Buyer's approval), but such estoppel certificate shall contain no statement or
information which is materially inconsistent with the provisions of such
tenant's lease as delivered to Buyer.  If the Partners are unable to obtain such
estoppel certificates from all of the tenants of the Property (excluding
Anchors) but if the Partners obtain a Tenant Estoppel Certificate from tenants
whose total aggregate gross leasable area is not less than seventy percent (70%)
of the total aggregate gross leasable occupied area (excluding, however, Anchors
and short term kiosk license agreements or other short term specialty leases or

condition of providing Tenant Estoppel Certificates the Partners shall execute
and deliver a Partners' estoppel ("Partners' Estoppel Certificate") as a
condition to closing in the form of Exhibit "J" attached hereto with respect to
space for which Tenant Estoppel Certificates were not received from tenants.
The certifications contained in the Partners' Estoppel Certificate shall survive
the Closing; provided, however, any Tenant Estoppel Certificate received by
Buyer after the Close of Escrow shall enable the Partners to remove their
certification with respect to the Tenant for which the Tenant Estoppel
Certificate is received to the extent that such Tenant Estoppel Certificate
confirms the information set forth in Partners' Estoppel Certificate.  Buyer
shall use Buyer's best efforts to assist the Partners in obtaining the Tenant
Estoppel Certificates.

          (iv)   Estoppel certificates (the "Anchor Estoppel Certificates"), in
the form attached hereto as Exhibit "K", from Lord & Taylor, Marshall Fields

                                       8

use their best efforts to obtain such estoppel certificates.  The delivery of

"L", duly executed and acknowledged by each Partner.

incorporation of each Partner, dated not more than ten (10) days prior to the
Closing Date, certifying the good standing of each Partner.

          (xi)   Copies of the Articles of Organization of each Partner and any
amendments thereto, certified by the Secretary of State of their respective
states of incorporation, as of a date not more than ten (10) days prior to the

effect that the Articles of Organization thereof, as certified by the Secretary
of State aforesaid, have not been further amended, revised, restated, canceled
or rescinded up to and including the Closing Date.

          (xii)  An opinion or opinions of counsel for each Partner dated as of
the Closing Date, in the form of Exhibit "M" attached hereto and otherwise in
form and substance reasonably acceptable to Buyer.

required by the Title Company to be executed or provided by the Partners as a
condition to the issuance of the Title Policy at the Closing pursuant to the

          (e) Title Insurance.  Ticor Title Insurance Company ("Title Company")
              ---------------                                                  
shall furnish to Buyer an American Land Title Association owners policy of title
insurance (together with reinsurance and direct access agreements reasonably
acceptable to Buyer) (the "Title Policy") in the amount of the Purchase Price
from the Title Company, insuring fee title to the Property vested in Buyer as of
the Close of Escrow, subject only to the matters approved by Buyer as provided
herein (the "Permitted Exceptions") with extended coverage endorsement over the
standard printed exceptions and containing the following endorsements:  Zoning
3.1 with parking, a location endorsement insuring accuracy of the Survey (as
hereinafter defined), an access endorsement, a contiguity endorsement, a tax
parcel endorsement, a non-imputation endorsement and an endorsement insuring
that there are no violations of covenants or restrictions of record, if
available.  The cost of the base Title Commitment, Title Policy and all search
charges shall be borne equally by Buyer and the Partners.  The Property is
subject to various mechanics liens relating to tenant improvement work
contracted for by tenants which liens are more specifically listed on Exhibit
"O" attached hereto (the "Mechanics Liens").  The Partners will credit the
Buyers for the sums which the Partnership is obligated to expend for the
mechanics liens listed as items 42, 43, 44, and 55 (the "Credit").  Buyers will
use appropriate and customary measures to compel the tenants responsible for the
mechanics liens to discharge such liens.  If Buyers are unsuccessful in
resolving such liens after application of the Credit and other security held by
Buyers for discharge of such liens, if any, then the Partners shall pay Buyers
such unreimbursed lien claims in conjunction with the Final Closing adjustment
(as provided herein).  In order to facilitate Buyer's financing at Closing the
Partners will enter into an indemnity agreement with the Title Company with
respect to the Mechanics Liens.  The cost of the endorsements shall be borne
solely by Buyer.

          Attached hereto as Exhibit "P" is the Title Commitment issued by the
Title Company showing the state of title of the Property.  Buyer shall have no
obligation to accept or approve any exceptions on the Title Commitment except to
the extent mentioned above.  Buyer will notify the Partners within five (5) days
of Buyer's objections to any of the exceptions to title. Buyer and the Partners
will act in good faith to resolve any unacceptable title exceptions.  If the
Partners do not agree to remove any title exceptions which are unacceptable to
Buyer, then Buyer's sole right is to accept such item without discount or credit
and close this transection or terminate this agreement for failure of condition
precedent, in which case Buyer shall be entitled to a full refund of Buyer's
Deposit.  If after Buyer's approval of the Title Commitment any additional items
except the Permitted Exceptions are shown in the Title Policy to be provided to
Buyer hereunder and the Partners fail to remove the same or cause the Title
Company to insure over such item by endorsement

                                      11
<PAGE>
 
approved by Buyer prior to the Close of Escrow, Buyer shall have the right to
either (x) complete the transactions hereunder and accept the effect of the
additional items; provided, however, that Buyer shall thereupon have the right
to deduct from the Purchase Price the amount of any such additional item which
is a monetary lien of a fixed and ascertainable amount not in excess of Five
Hundred Thousand Dollars ($500,000); or (y) terminate the Escrow as Buyer's sole
and exclusive remedy prior to the Close of Escrow and the Deposit and all
interest earned thereon shall be returned to Buyer in full.  The Partners shall
remove or insure over any monetary liens which show as an exception to the Title
Commitment and not approved above.  The Partners shall execute and deliver such
affidavits as may reasonably be required by the Title Company, including an
affidavit to enable the Title Company to limit any exception in policies for
"rights of Tenants or rights of parties in possession" to the "occupancy rights
of Tenants as Tenants only under the space leases with no right or option to
purchase the Property or any portion thereof" listed in the current schedule to
be delivered by the Partners to Buyer at the Close of Escrow as provided herein.
At least ten (10) business days prior to the date of the Close of Escrow, the
Title Company shall furnish Buyer with a pro forma of each Title Policy
                                         --- -----                     
(including all of the co-insurance, reinsurance and direct access agreements
which constitute part thereof) substantially as the Title Company is prepared
(subject to events occurring after the date and time of such pro forma and prior
                                                             --- -----          
to Close of Escrow) to bind itself to issue as the Title Policy.

          (f) Survey.  The Partnership has delivered to Buyer an ALTA Survey of
              ------

          (g) Duties of Escrow Holder.  On the Close of Escrow, Escrow Holder
              -----------------------                                        
shall (1) deliver to Buyer the Assignment of PIC's Partnership Interest, the
Assignment of Grosvenor's Partnership Interest, and the Title Policy, (2)
deliver to the Partners the cash proceeds in accordance with the Closing
Statement, and (3) forward to Buyer and the Partners, in duplicate, an
accounting of all funds received and disbursed and copies of all executed
documents deposited into Escrow.

          (h) Prorations - General.  All rentals, revenues and other income of

and other regular operating expenses of the Property, if any, shall be paid or
shall be prorated between the Partners and Buyer in accordance with the
provisions set forth in Sections 2.3(h) through (q) inclusive.  Buyer and
Partners acknowledge that some or all of the tenants under Leases and the
Anchors may claim or be entitled to adjustments of past or future CAM (common
area maintenance) obligations and real property tax and assessment reimbursement
obligations based upon the termination of the I. Magnin lease

(the area currently leased by General Cinema) and the General Cinema lease.  The
parties have adjusted the purchase price (the "I. Magnin/GCC Adjustment") due to
current claims and potential future claims for repayment of past CAM charges and
reduction of future CAM obligations and past real property tax and assessment
reimbursement charges and reduction of future real property tax and assessment
reimbursement obligations.  In consideration of the I. Magnin/GCC Adjustment,
Buyer releases Partners for any such claims or liabilities relating to CAM and
real property tax reimbursement charges and adjustments for tenants or Anchors
relating to the I. Magnin termination and the General Cinema leasing and no
proration, credit or adjustment shall be made in regard to claims, losses,
costs, damages, refunds or liabilities incurred by Buyer in regard thereto.  For
purposes of the prorations and adjustments to be made, Buyer shall be deemed to
own the Property and therefore shall be entitled to any revenues and responsible
for any expenses for the entire day upon which the Closing occurs.  Any
apportionments and prorations which are not expressly provided for below shall
be made in accordance with the customary practice in the metropolitan Chicago,
Illinois area.  The Partners and Buyer shall cause their accountants to prepare
the schedules of adjustments (the "Closing Statement") prior to the Proration
Date.  Any net adjustment in favor of Buyer shall be paid in the form of a
credit to the Purchase Price.  Any net adjustment in favor of the Partners shall
be paid in cash or cash equivalent by Buyer to the Partners at Closing.  A copy
of the Closing Statement agreed upon by the Partners and Buyer shall be executed
by both the Partners and Buyer and delivered to the Title Company at the
Closing.  All Rentals received by the Partners or any of its affiliates or its
general partners related to any period after the Proration Date shall be
immediately paid to Buyer.  The parties shall make an interim closing adjustment
(the "Interim Closing Adjustment") on July 31, 1998 and a final closing
adjustment (the "Final Closing Adjustment") on October 1, 1999.  The Interim
Closing Adjustment and the Final Closing Adjustment are jointly referred to as
the "Closing Adjustments".

the Partners and Buyer in the manner provided in this Subsection 2.3(g)(iii).
Such proration shall be made on a Lease-by-Lease basis and shall be based upon
the fiscal year set forth in each Lease for the determination of Percentage
Rent. The actual fiscal year for Percentage Rent during which the Closing occurs
is hereinafter referred to as the "Applicable Percentage Rent Fiscal Year". To
the extent a Tenant makes monthly or quarterly interim payments on account of
Percentage Rent, the Partners shall initially retain all such interim payments
of Percentage Rent received by the Partners up to and including the Proration
Date until a Closing Adjustment occurs and Buyer shall initially retain all such
interim payments of Percentage Rent received by Buyer after the Proration Date
until a Closing Adjustment occurs. At each Closing Adjustment, the Partners and
Buyer shall prorate the total annual Percentage Rent due from a Tenant for such
Tenant's Applicable Percentage Rent Fiscal Year as follows: (a) the Partners
shall be entitled to the portion of the Percentage Rent payable by each Tenant
equal to the product obtained by multiplying the total annual Percentage Rent
paid by each such Tenant by a fraction, the numerator of which is the number of
days in the Applicable Percentage Rent Fiscal Year up to and including the
Proration Date and the denominator of which is the number of days in the
Applicable Percentage Rent Fiscal Year; and (b) Buyer shall be entitled to the
portion of the Percentage Rent payable by each Tenant equal to the product
obtained by multiplying the total annual Percentage Rent paid by each such
Tenant by a fraction, the numerator of which is the number of days in the
Applicable Percentage Rent Fiscal Year after the Proration Date and the
denominator of which is the number of days in the Applicable Percentage Rent
Fiscal Year.

          (iv)   Delinquent Rental.  As used herein, "Delinquent Rentals" means
                 -----------------                                             
Rentals which are due and payable by a Tenant on or prior to the Proration Date
but which have not been paid by the Proration Date.  Delinquent Rentals shall be
prorated between the Partners and Buyer as of the Proration Date, but not

                                      14
<PAGE>
 
until they are actually collected by Buyer.  Buyer shall have the right after
the Closing to collect Delinquent Rentals relating to the period prior to the
Proration Date, but shall not be obligated to do so.  Upon the Final Closing
Adjustment, any Delinquent Rentals which have not as yet been paid shall be
assigned to the Partners.  After the Closing and continuing through and after
the Final Closing Adjustment, without the express written consent of Buyer, the
Partners shall not take, nor cause Buyer to take, any action against a Tenant
owing Delinquent Rentals which would affect such Tenant's right to occupy its
leased premises.  Rentals collected by Buyer after the Closing, shall be applied
in the following order of priority:  (a) first, to the particular rental
obligation, if any, for which the Tenant designates the payment has been made
(e.g., by a notation on the Tenant's check or in an accompanying cover letter or
- -----                                                                           
if the payment is made in response to an invoice submitted to the Tenant); and
(b) secondly, against the Tenant's Rental obligations in reverse chronological
order in which they accrue.  All Delinquent Rentals received by Buyer or any of
its affiliates after the Proration Date shall be immediately applied in
accordance with the above and any amount owing to the Partners shall be
immediately paid upon application, less the amount of any management fee or
compensation paid or due with respect to such Delinquent Rentals; however, in no
event later than thirty (30) days after collection.

               (A)  The Partners shall have the right to commence litigation
     against the Tenants owing Delinquent Rents (the "Delinquent Tenants") to
     collect the Delinquent Rentals, which pursuant to the above, the Partners
     are entitled to as and when collected.  The Partnership shall assign to the
     Partners the necessary rights under the subject leases to commence such
     litigation.  The Partners may proceed with counsel of their own choosing,
     and at its own expense, to collect any such Delinquent Rentals due by the
     Delinquent Tenants which are allocable to the Partners, provided that the
     Partners shall not seek (i) termination of any Lease; (ii) eviction of any
     Delinquent Tenant; nor (iii) to levy against the Delinquent Tenant's
     interests in the Lease, all without the prior written consent of Buyer.

               (B)  If a Delinquent Tenant owes Delinquent Rental which is
     properly allocable to both the Partners and Buyer, the Partners and Buyer
     shall cooperate in collecting such Delinquent Rental.  If the Partners
     desire to commence litigation as to Delinquent Rentals properly allocable
     to it, but Buyer does not so desire to commence litigation, then the
     Partners may commence litigation as set forth in (A) above.  If both
     parties desire to commence litigation, Buyer shall

                                      15
<PAGE>
 
     institute such litigation on the Partnership's behalf and the Partners'
     share of any recovery of the Delinquent Rentals from such litigation, after
     the payment of all expenses in connection therewith, shall be apportioned
     between Buyer and the Partners in accordance with this Subsection
     2.3(i)(iv).

          (j) Proration - Taxes and Assessments.  All non-delinquent real estate
              ---------------------------------                                 
and personal property taxes on the Property not otherwise reimbursed by Tenants
under their Leases or by a party to the REA shall be prorated between the
Partners and Buyer on an accrual basis, based upon the actual current tax bill
for the tax year in which the Closing occurs.  If the most recent tax bill
received by the Partners as of the Proration Date is not the actual current tax
bill, then the Partners and Buyer shall re-prorate the real estate and personal
property taxes at the Final Closing Adjustment if the actual current tax bill is
then available.  All amounts payable for real estate and personal property taxes
accruing up to and including the Proration Date shall be the obligation of the
Partners and all amounts payable for real estate and personal property taxes
accruing after the Proration Date shall be the obligation of Buyer.  If, after
the Proration Date, any additional or supplemental real estate and personal
property taxes are assessed against the Property by reason of back assessments,
corrections to previous tax bills or other events occurring up to and including
the Proration Date, the Partners and Buyer shall re-prorate the real estate and
personal property taxes at the Final Closing Adjustment to provide the
appropriate credit.  All amounts receivable pursuant to pending appeals for real
estate and personal property tax for the period up to and including the
Proration Date shall be the property of the Partners and all amounts recovered
for tax appeals for real estate and personal property taxes accruing after the
Proration Date shall be property of Buyer.  If any of the sums recovered by the
Partners pursuant to the real property tax appeal are payable to or owed as a
credit to tenants of the Property, such sums shall be paid to Buyer who shall
make the appropriate adjustments with the tenants.  Any delinquent real estate
and personal property taxes on the Property shall be paid by the Partners at the
Closing.

          (k) Proration - Operating Expenses and Insurance Premiums.  All costs,
              -----------------------------------------------------             
expenses, charges and fees for sewer, water, electricity, heat and air-
conditioning service and other utilities, common area maintenance charges,
insurance premiums, rental and privilege taxes, business occupation taxes,
promotional expenses, periodic charges payable under Service Contracts which are
assigned to Buyer, periodic fees payable under transferable Licenses and Permits
for the operation (as opposed to the construction) of the Property, periodic
charges under the REA, any payroll, employee benefits, employee related taxes or
other labor costs paid by the Partners (if assumed by

                                      16
<PAGE>
 
Buyer directly or indirectly) and any other costs incurred in the ordinary
course of business for the management and operation of the Property, and
insurance premiums shall be prorated between the Partners and Buyer on an
accrual basis, based on the actual number of days in the month during which the
Closing occurs.  The Partners shall be responsible for all such expenses that
are attributable to the period up to and including the Proration Date and Buyer
shall be responsible for all such expenses which are attributable to the period
after the Proration Date.  To the extent commercially reasonably and
practicable, the Partners shall obtain billings and meter readings as of the day
up to and including the Proration Date to aid in such prorations.  If billings
or meter readings as of the day up to and including the Proration Date are
obtained, adjustments of any costs, expenses, charges or fees shown thereon
shall be made in accordance with such billings or meter readings.

          (l) Proration - Security Deposits and Other Tenant Credits.  At the
              ------------------------------------------------------         
Closing, Buyer shall be credited with and the Partners shall be charged with an
amount equal to the sum of (i) the Security Deposits (and any interest due to
Tenants thereon, if any) being held by the Partners or any other person under
the Leases as designated on the Rent Schedule, plus (ii) the amount of any other
credits due Tenants.  Upon the Closing, the Partners shall be entitled to retain
the Security Deposits or other such credits due Tenants, for which Buyer has
been credited and the Partners have been charged pursuant to this Subsection
2.3(l).

          (m) Adjustment Dates.  On July 31, 1998, the Partners and Buyer shall
              ----------------

2.3(m).

          (i) General.  Payment of Delinquent Rentals collected by Buyer after
              -------                                                         
the Proration Date which have not been adjusted at the Interim Closing
Adjustment and which are attributable to the period up to and including the
Proration Date, shall be made by Buyer to the Partners when and as collected and
as soon as practicable following receipt.  All other adjustments or prorations
which could not be determined at the Closing or the Interim Closing Adjustment
due to the lack of actual statements, bills or invoices for the current period,
the year-end adjustment of Additional Rentals, the unavailability of final sales
figures or amounts for Percentage Rent or for any other reason shall be made at
the Final Closing Adjustment.  Any net adjustment determined at each respective
Adjustment Date in favor of Buyer shall be paid in cash or cash equivalent by
the Partners to Buyer no later than twenty (20) days after the

                                      17

<PAGE>
 
respective Adjustment Date.  Any net adjustment in favor of the Partners shall
be paid in cash or cash equivalent by Buyer to the Partners no later than twenty
(20) days after the respective Adjustment Date.  Any reduction or credit paid to
or benefiting any tenant or Anchor occasioned by the I. Magnin/GCC Adjustment
shall be treated as if such reduction had not been given or such credit had not
been paid for the purpose of adjustments required by this Agreement.

          (ii) Additional Rental Adjustment.  The actual amount of Additional
               ----------------------------                                  
Rentals paid by each Tenant of the Property for the annual period in which the
Proration Date occurs (as distinguished from the estimated amounts prorated as
of the Proration Date pursuant to Subsection 2.3(i)(ii) above) shall be
separately prorated between the Partners and Buyer as of the Proration Date
based on the actual number of days in the annual period during which the
Proration Date occurs.  Buyer shall pay to the Partners an amount (if any) equal
to the excess of (1) the product obtained by multiplying (A) the total amount of
Additional Rentals paid by the Tenant to the Partners and Buyer for the annual
period  during which the Proration Date occurs, by (B) a fraction, the numerator
of which is the number of days in the annual period up to and including the
Proration Date and the denominator of which is the total number of days in the
annual period over (2) the sum of (X) the total amount of the monthly or
quarterly payments of estimated Additional Rentals actually collected by the
Partners or the Partnership prior to the Close of Escrow from the Tenant for the
months or quarters preceding the month or quarter during which the Proration
Date occurs, (Y) a pro-rated portion of the monthly or quarterly estimated
Additional Rentals paid by the Tenant for the month or quarter during which the
Proration Date occurs (i.e., the amount of the adjustment pursuant to Section
                       ----                                                  
2.3(i)(ii) above) and (Z) the entire amount of the monthly or quarterly
estimated Additional Rentals which constitutes Delinquent Rentals and which is
collected by Buyer or the Partnership from the Tenant after the Proration Date
and paid over to the Partners by Buyer pursuant to Subsection 2.3(i)(iv) above.
If, for any Tenant, the Additional Rent received by the Partners, up to and
including the Proration Date, exceeds the product obtained above, the Partners
shall pay the excess to Buyer.  If the total sum of all advance payments of
projected Additional Rentals exceeds the Additional Rentals actually due from
the Tenant for the annual period in which the Proration Date occurs, Buyer shall
remit or credit the Tenant with such excess.

         (iii) Percentage Rent Adjustment.  To the extent the sum of all
interim payments on account of Percentage Rent collected by the Partners
from each Tenant for the Applicable Percentage Rent Fiscal Year exceeds the
amount of Percentage Rent to which the Partners are entitled with respect to
such Tenant pursuant to Subsection 2.3(i)(iii), the Partners

                                      18

<PAGE>
 
shall pay such excess to Buyer.  To the extent the sum of all interim payments
on the account of Percentage Rent collected by Buyer from each Tenant for the
Applicable Percentage Rent Fiscal Year exceeds the amount of Percentage Rent to
which Buyer is entitled with respect to such Tenant, then Buyer shall pay such
excess to the Partners.  Any such adjustment of interim payments received and
actual Percentage Rent payable shall be made on a Lease-by-Lease basis (as
opposed to aggregating all interim payments received by the Partners from all
Tenants and offsetting the same against the entire amount of Percentage Rent
payable by all Tenants).  If the total sum of the interim payments on account of
Percentage Rent collected by the Partners plus the interim payments on account
of Percentage Rent collected by Buyer exceeds the Percentage Rent actually due
from the Tenant, Buyer shall remit or credit Tenant with such excess and the
Partners and Buyer shall make any necessary adjustment between them in
accordance with the preceding provisions of this Subsection 2.3(m)(iii).

          (iv) No Further Adjustments.  On the Final Adjustment Date, final
               ----------------------                                      
prorations shall be made and, to the extent necessary, Buyer and the Partners
shall estimate items for which final sums are not available.  Except for:  (a)
additional or supplemental real estate taxes, real estate tax credits or
rebates, or other adjustments to real estate taxes due to back assessments,
corrections to previous tax bills or real estate tax appeals or contests, and
(b) any Additional Rentals or any Percentage Rent which may be contested by
Tenants or cannot be computed by the Final Adjustment Date, the Final Closing
Adjustment shall be conclusive and binding upon the Partners and Buyer.

          (n) Leasing Commissions and Tenant Improvements.  Any and all leasing
              -------------------------------------------                      
commissions due and tenant improvements with respect to Leases in existence on
the date hereof including the Pending Leases (as hereinafter defined in Exhibit

of such fact.  If such damage or destruction is "material", either Buyer or the
Partners shall have the option to terminate this Agreement upon written notice

destruction is not material, this Agreement shall not terminate but the Partners
shall be entitled to the proceeds of any insurance maintained by or on behalf of
the Partners and the Partners shall repair or restore the damage or destruction
to the same condition as existed prior to the casualty as soon as reasonably
practical but in no event more than 60 days after the casualty, and upon the

          neither given nor received any notice of any such default or
          occurrence.

     DATE"), which Base Balance Sheet will include all adjustments necessary to
     give effect to each transaction included in the Restructuring as of the
     date of consummation of such transaction, if such transaction is
     consummated prior to such month end, or otherwise all pro forma adjustments
     necessary to give effect to such transactions as of the Base Balance Sheet
     Date; (ii) a statement setting out in reasonable detail the calculation of
     the amount of Parent Receivables and the amount of Finance Receivables
     based upon the latest available financial information as of the date of the

     pro forma Restructuring adjustment.  The Base Balance Sheet shall be
     prepared by the Sellers in good faith in accordance with the procedures set
     forth in Exhibit B hereto.

          Section 2.03.  Closing.  The closing (the "CLOSING") of the purchase

     Lexington Avenue, New York, New York, at 10:00 AM (New York time) on May
     31, 1998, or at such other time as Buyer and Parent may agree.  At the

     as set forth on the Base Balance Sheet; plus (iii) in the event of a Note
     Election, the sum of the amount of the Parent Receivables and the amount of

     delivered pursuant to Section 2.02; minus (iv) the Deposit Amount (as
                                   ----                                   
     defined below).  The Preliminary Purchase Price shall be paid in United
     States dollars, in immediately available funds by wire transfer to an
     account of Parent with a bank in New York City designated by Parent, by
     notice to Buyer, not later than two business days prior to the Closing Date
     (or if not so designated, then by certified check of Buyer certified by, or
     by an official bank check of a bank which is a member of the New York

     to the order of Parent in such amount).  The Preliminary Purchase Price
     will be subject to certain adjustments as described below.
          (b)  Parent shall cause the Sellers (or, as appropriate, MEPC Finance)
     to deliver to Buyer (i) certificates for the Shares duly endorsed or

     transfer stamps affixed thereto and (ii) in the event of a Note Election,

          (c)  In the event of a Payment Election, Buyer shall transfer as a
     capital contribution or loan to the Company Group at Closing cash, payable
     in immediately available funds, in an amount sufficient to enable the
     Company Group to pay and Buyer and the Sellers will cause the Company Group
     to pay at Closing (i) to Parent the amount of the Parent Receivables and

          (d)  The Preliminary Purchase Price shall be allocated first to the
     Notes (in the event of a Note Election), in an amount equal to the amount
     thereof, and then to the Shares, as set forth in a Schedule to be agreed
     upon by Buyer and Parent and delivered at the Closing.  Any difference
     between the Preliminary Purchase Price and the Purchase Price shall be
     allocated to the Notes (in the event of a Note Election) and to the Shares
     as set forth in a schedule to be agreed upon by Buyer and Parent at the
     time the Purchase Price is determined.

          Section 2.04.  Closing Balance Sheet.  (a) As promptly as practicable,
     but no later than 90 days, after the Closing Date, Buyer will cause to be
     prepared and delivered to Parent a combined balance sheet of the Company
     Group as of the close of business on the Closing Date (the "CLOSING BALANCE
     SHEET"), together with a report of Coopers & Lybrand or Ernst & Young
     thereon, and a certificate based on such Closing Balance Sheet setting
     forth Buyer's calculation of stockholders' equity (the "STOCKHOLDERS'
     EQUITY AMOUNT"), the amount of the Parent Receivables, the amount of the
     Finance Receivables (together with the amount of the Parent Receivables,
     the "RECEIVABLES AMOUNT"), in each case before giving effect to any payment
     thereof pursuant to Section 2.03.  The Closing Balance Sheet shall be
                                 ----                                     
     prepared by Buyer in good faith in accordance with the procedures set forth
     in Exhibit B hereto.
          (b)  If Parent disagrees with Buyer's calculation of the Stockholders'
     Equity Amount or Buyer's calculation of the Receivables Amount, in each
     case delivered pursuant to Section 2.04(a), Parent may, within 20 days
                                        -------                            
     after delivery of the documents referred to in Section 2.04(a), deliver a
                                                            -------           
     notice to Buyer disagreeing with such calculation and setting forth
     Parent's calculation of such amounts.  Any such notice of disagreement
     shall specify those items or amounts as to which Parent disagrees, and
     Parent shall be deemed to have agreed with all other items and amounts
     contained in the Closing Balance Sheet and the Buyer's calculation of the
     Stockholders' Equity Amount and the Receivables Amount, in each case
     delivered pursuant to Section 2.04(a).
                                   ------- 
          (c)  If a notice of disagreement shall be duly delivered pursuant to
     Section 2.04(b), Buyer and Parent shall, during the 30 days following such
             -------                                                           
     delivery, use their best efforts to reach agreement on the disputed items
     or amounts in order to determine, as may be required, the Final
     Stockholders' Equity Amount (as defined below) and the Final Receivables
     Amount (as defined below) which amounts shall not be less than the amounts
     thereof shown in Buyer's calculations delivered pursuant to Section 2.04(a)
                                                                         -------
     nor more than the amounts thereof shown in Parent's calculation delivered
     pursuant to Section 2.04(b).  If, during such period, Buyer and Parent are
                         -------                                               
     unable to reach such agreement, they shall promptly thereafter cause Arthur
     Andersen LLP ("ARTHUR ANDERSEN") to promptly to review this Agreement and
     the disputed items or amounts for the purpose of calculating the Final
     Stockholders' Equity Amount and the Final Receivables Amount.  In making
     such calculation, Arthur Andersen shall consider only those items or
     amounts in the Closing Balance Sheet or Buyer's calculation of the
     Stockholders' Equity Amount and/or Buyer's calculation of the Receivables
     Amount as to which Parent has disagreed.  Arthur Andersen shall deliver to
     Buyer and Parent, as promptly as practicable, a report setting forth such
     calculations.  Such report shall be final and binding upon Buyer and
     Parent.  The cost of such review and report shall be borne (i) by Buyer if
     the difference between the Final Stockholders' Equity
<PAGE>
 
     Amount plus the Final Receivables Amount and Buyer's calculation of the
     Stockholders' Equity Amount plus Buyer's calculation of the Receivables
     Amount delivered pursuant to Section 2.04(a) is more than the difference
                                          -------
     between the Final Stockholders' Equity Amount plus the Final Receivables
     Amount and Parent's calculation of the Stockholders' Equity Amount plus
     Parent's calculation of the Receivables Amount delivered pursuant to
     Section 2.04(b), (ii) by Parent if the first such difference is less than
             -------
     the second such difference and (iii) otherwise equally by Buyer and Parent.


          "FINAL STOCKHOLDERS' EQUITY AMOUNT" means the Stockholders Equity
     Amount as shown in Buyer's calculation delivered pursuant to Section
                                                                         
     2.04(a), if no notice of disagreement with respect thereto is duly
     -------                                                           
     delivered pursuant to Section 2.04(b); or if such a notice of disagreement

          (d)  Buyer and the Sellers agree that they will, and agree to cause
     their respective independent accountants and each member of the Company
     Group to, cooperate and assist in the preparation of the Closing Balance
     Sheet, the calculation of the Final Stockholders' Equity Amount and the
     Final Receivables Amount and in the conduct of the reviews referred to in
     this Section, including without limitation, the making available to the
     extent necessary of books, records, work papers and personnel.

          Section 2.05.  Adjustment to Preliminary Purchase Price.  (a) The
     Preliminary Purchase Price will be adjusted as follows: if the sum of (i)
     the Final Stockholders' Equity Amount plus (ii) the Final Receivables
     Amount exceeds the sum of (iii) the stockholders equity as set forth on the
     Base Balance Sheet (the "BASE STOCKHOLDERS' EQUITY AMOUNT") plus (iv) the
     Receivables Amount set forth on the Base Balance Sheet (the "BASE
     RECEIVABLES AMOUNT"), Buyer shall pay to Parent, as an adjustment to the
     Preliminary Purchase Price, in the manner and with interest as provided in
     Section 2.05(b), the amount of such excess.  If the sum of (v) the Base
             -------                                                        
     Stockholders' Equity Amount plus (vi) the Base Receivables Amount exceeds
     the sum of (vii) the Final Stockholders' Equity Amount plus (viii) the
     Final Receivables Amount, Parent shall pay to Buyer, as an adjustment to
     the Preliminary Purchase Price, in the manner and with interest as provided
     in Section 2.05(b), the amount of such excess.  The Preliminary Purchase
                -------                                                      
     Price as so adjusted is referred to herein as the "PURCHASE PRICE".
          (b)  Any payment pursuant to Section 2.05(a) shall be made at a
                                               -------                   
     mutually convenient time and place within 10 days after the Final
     Stockholders' Equity Amount has been determined by delivery by Buyer or
     Parent, as the case may be, of a certified or official bank check payable
     in immediately available funds to the other party or by causing such
     payments to be credited to such account of such other party as may be
     designated by such other party.  The amount of any payment to be made
     pursuant to Section 2.05(a) shall bear interest from and including the
                         -------                                           
     Closing Date to but excluding the date of payment at a rate per annum 
<PAGE>
 
     equal to the rate of interest announced by Morgan Guaranty Trust Company of
     New York (the "RATE") from time to time as its Base Rate in New York City
     in effect from time to time during the period from the Closing Date to the
     date of payment. Such interest shall be payable at the same time as the
     payment to which it relates and shall be calculated daily on the basis of a
     year of 365 days and the actual number of days elapsed.

          Section 2.06.  Deposit.  If this Agreement is not terminated by Buyer
     pursuant to Section 12.01(b), on the business day immediately following the
                         --------                                               
     Effective Date, Buyer shall deposit with Chase Manhattan Bank (the "ESCROW
     AGENT") $20,000,000 (the "DEPOSIT") by a certified check of Buyer certified
     by, or by an official bank check of, a bank which is a member of the New
     York Clearing House Association payable in immediately available funds or
     by wire transfer of immediately available funds to such account as the
     Escrow Agent may specify. The Deposit Amount (as defined below) shall be
     held, invested and disbursed by the Escrow Agent in accordance with the
     terms set forth in the agreement attached hereto as Exhibit C (the "ESCROW
     AGREEMENT").  The Deposit (and any interest earned thereon) (the "DEPOSIT
     AMOUNT") shall be credited against the Preliminary Purchase Price at the
     Closing as provided in Section 2.03.  If this Agreement is terminated by
                                    ----                                     
     Parent pursuant to Section 12.01(c) and any of the conditions set forth in
                                --------                                       
     Section 12.02 that would, in accordance with Section 12.02, give rise to
             -----                                        -----              
     liability on the part of Buyer (the "BUYER BREACH CONDITIONS") have
     occurred, the Sellers shall have the right to retain the Deposit; provided
     that, prior to terminating this Agreement, the Sellers will give written
     notice to Buyer of such condition and will give Buyer 10 days from the date
     of such notice to cure such condition (and if such condition is cured
     within such 10-day period, the Sellers may not terminate this Agreement on
     account thereof); provided further that retention of the Deposit Amount
     shall not affect the availability of any other remedies that may be
     available to the Sellers under this Agreement or applicable law. If this
     Agreement is terminated pursuant to any other paragraph of Section 12.01 or
                                                                        -----   
     pursuant to Section 12.01(c) under circumstances where no Buyer Breach
                         --------                                          
     Condition is satisfied, the Deposit Amount shall be returned to Buyer and,
     subject to Section 12.02, the Sellers shall not have any liability to
                        -----                                             
     Buyer.


          Section 2.07.  Cost to Completion Adjustments.  (a) The Preliminary
     Purchase Price will be reduced by (i) the amount of all tenant improvement
     costs and allowances and brokerage commissions which have been agreed to be
     paid by landlord with respect to space leases in effect for the Properties
     on the date of this Agreement and which have not been paid by any member of
     the Company Group as of the Closing Date and (ii) the amount estimated as
     of Closing that will be required, following the Closing Date, to complete
     (not including any tenant improvement costs or allowances or any leasing
     commissions) the planned development program with respect to Northridge
     Fashion Center and Regency Square Mall in accordance with plans and
     specifications for each such Property delivered to Buyer not later than 15
     days prior to the Closing Date (the "DEVELOPMENT PLANS"), which plans and
     specifications shall not be materially different from those made available
     to Buyer prior to the date hereof (together, the "CONSTRUCTION COMPLETION
     AMOUNT"), the calculation of which shall be without regard to any actions
     taken by Buyer or any developments arising after the Closing Date.  The
     amount calculated pursuant to Section 2.07(a)(ii) shall include the cost of
                                           -----------                          
     paving, grading and other offsite and onsite work; barricades, security,
     directional signs and other general conditions; roof, structural and other
     shell work; mall and common area finish work; parking, lighting,
     landscaping, exterior signage and other developer work; permits and
     licenses; architectural, engineering and general contractor's fees and
     legal fees, in each case, only to the extent required to complete the
     development program set forth under the Development Plans.  Notwithstanding
     anything to the contrary contained in this Section 2.07(a), for purposes of
                                                        -------                 
     this Section 2.07(a), the parties agree that the 
                  -------                                                     
<PAGE>
 
     tenant improvement costs and allowances and brokerage commissions for the
     theatre lease at Valley Plaza Mall shall be deemed to be $5,200,000. The
     Sellers shall cause the site work for the proposed theatre tenant at Valley
     Plaza Mall to be completed prior to Closing (or, to the extent not
     completed, Buyer shall be entitled to a credit at Closing for the unpaid
     cost thereof).
          (b)  From and after the date hereof and until Closing, the Sellers
     shall cause the members of the Company Group to (i) take, at their own
     expense, all actions reasonably necessary to continue the construction,
     renovation, development or redevelopment of Northridge Fashion Center and
     Regency Square Mall, in each case, substantially in accordance with the
     plans and specifications therefor made available to Buyer prior to the date
     hereof and to keep a designated representative of Buyer informed with
     respect to the progress and implementation of such plans, (ii) use all
     reasonable efforts to continue negotiating leases in respect of leasable
     space in each of such Properties, including the Valley Plaza Mall theatre
     lease, (iii) use all reasonable efforts to obtain the consent of the anchor
     tenants to the proposed amendments to the Northridge Fashion Center REA (it
     being understood that such consents are not required to be obtained prior
     to Closing).
          (c)  Not later than 15 days prior to the Closing Date, Parent shall
     deliver to Buyer in writing its good faith calculation of the Construction
     Completion Amount.  If Buyer agrees with the Construction Completion Amount
     as calculated by Parent, such calculation shall be binding upon Parent and
     Buyer and will constitute the Construction Completion Amount for purposes
     of calculating the Preliminary Purchase Price.  If Buyer disagrees with the
     calculation made by Parent, Buyer shall deliver to Parent, within 5 days of
     receipt of Parent's calculation, a written notice specifying the basis for
     its disagreement and setting forth its calculation of the Construction
     Completion Amount.  Failure to deliver a notice of disagreement within any
     such 5-day period shall be deemed to constitute agreement to such
     calculation.  If a notice of disagreement is delivered within such 5-day
     period, Buyer and Parent shall negotiate in good faith to resolve the
     disagreements.  If no agreement is reached as to the Construction
     Completion Amount, Buyer and Parent shall refer the disputed issues for
     resolution to an appropriate Person of recognized national standing who has
     been agreed upon by Parent and Buyer (a "DESIGNATED PERSON").  The
     Designated Person shall resolve such issues and determine the Construction
     Completion Amount.  The fees and expenses of the Designated Person shall be
     borne (i) by Buyer if the difference between Buyer's calculation of the
     Construction Completion Amount and the Construction Completion Amount
     determined by the Designated Person is greater than the difference between
     Parent's calculation of the Construction Completion Amount and the
     Construction Completion Amount determined by the Designated Person, (ii) by
     Parent if the first such difference is less than the second such difference
     and (iii) otherwise equally by Buyer and Parent.

          If Parent and Buyer are unable to agree on a Designated Person, each
     of Parent and Buyer will select a Designated Person (the "PARENT DESIGNATED
     PERSON" and the "BUYER DESIGNATED PERSON", respectively).  The Parent
     Designated Person and the Buyer Designated Person will select a third,
     independent Designated Person (the "THIRD DESIGNATED PERSON").  The Parent
     Designated Person, the Buyer Designated Person and the Third Designated
     Person (collectively, the "DESIGNATED COMMITTEE") will resolve the issues
     and will determine, by a majority vote of the three, the Construction
     Completion Amount.  The determination of the Construction Completion Amount
     shall be binding upon Parent and Buyer; provided that the Construction
     Completion Amount so determined shall not exceed the higher of the
     Construction Completion Amount or be less than the lower of the
     Construction Completion Amount calculated by Parent and Buyer.  The Parent
     and Buyer will pay the fees and expenses of its own Designated Person, and
     if a Third Designated Person is engaged, the fees and expenses of the Third
     Designated Person will be paid one-half by Parent and one-half by Buyer.
<PAGE>
 
          If Parent and Buyer are unable to agree on the Construction Completion
     Amount or if the Designated Person(s) has (have) not made a determination
     as to the Construction Completion Amount, in each case by the Closing Date,
     the Construction Completion Amount for purposes of calculating the
     Preliminary Purchase Price shall be the calculation originally delivered by
     Parent (the "ESTIMATED CONSTRUCTION COMPLETION AMOUNT").  In such event, if
     the Estimated Construction Completion Amount is less than the Construction
     Completion Amount, determined in accordance with the procedures of this
     Section 2.07, Parent shall pay to Buyer the difference between the two
             ----                                                          
     amounts.  Such payment shall be made within 10 days after the Construction
     Completion Amount has been determined pursuant to this Section 2.07 and
                                                                    ----    
     shall be made in immediately available funds by wire transfer to an account
     of Buyer designated by Buyer, by notice to Parent, (or if not so
     designated, then by certified check of Parent certified by, or by an
     official bank check of a bank which is a member of the New York Clearing
     House Association payable in immediately available funds directly to the
     order of Buyer in such amount).  The amount of any payment to be made
     pursuant to Section 2.07(a) shall bear interest from and including the
                         -------                                           
     Closing Date to but excluding the date of payment at the Rate in effect
     from time to time during the period from the Closing Date to the date of
     payment.  Such interest shall be payable at the same time as the payment to
     which it relates and shall be calculated daily on the basis of a year of
     365 days and the actual number of days elapsed.

     aggregate, would reasonably be expected to have a Material Adverse Effect
     or which in any manner challenges or seeks to prevent, enjoin, alter or
     materially delay the transactions contemplated by this Agreement.  None of
     the Sellers nor any other member of the Company Group is a party to or is
     bound by or in default or, with the passing of time or giving of notice or
     both, would be in default with respect to any outstanding order, writ,
     injunction, judgment or decree of any court or governmental entity which,
     individually or in the aggregate, would reasonably be expected to have a
     Material Adverse Effect.

                                                       ----

     operations, employees, officers or directors of the Company Group.  Except
     as set forth on Schedule 3.13, there are no material claims by any member
                              ----                                            
     of the Company Group pending under any of such policies or bonds as to
     which coverage has been questioned, denied or disputed by the underwriters
     of such policies or bonds or in respect of which such underwriters have
     reserved their rights.  Such policies and bonds are in full force and
     effect and all premiums have been paid through the date hereof.  To the
     knowledge of the Sellers, no Seller or any other member of the Company
     Group has received notice or has knowledge of (a) any material violation
     with respect to any of such insurance policies or bonds or (b) any material
     request or demand by the underwriters of any such insurance policies and
     bonds that any work or alteration be performed or made with respect to any
     of the Properties.

          Section 3.14.  Brokers and Finders.  Except for Goldman, Sachs & Co.,
     whose fees will be paid by the Sellers, there is no investment banker,
     broker, finder or other intermediary which has been retained by or is
     authorized to act on behalf of the Sellers or any member of the Company
     Group who might be entitled to any fee or commission in connection with the
     transactions contemplated by this Agreement.

          Section 3.15.  Employees.  Schedule 3.15 sets forth a true and
                                              ----                      
     complete list of the names, titles, annual salaries and other compensation
     of all officers of the Company Group and all other employees of the Company
     Group whose annual base salary exceeds $75,000.

     Section 3.16.  Employee Benefit Plans.  (a) Schedule 3.16 identifies each
                                                          ----                
     Employee Plan.  Seller has made available to Buyer copies of the Employee
     Plans (and, if applicable, related trust agreements) and all amendments
     thereto and written interpretations thereof together with the most recent
     annual report (Form 5500 including, if applicable, Schedule B thereto) and
     the most recent actuarial valuation report prepared in connection with any
     Employee Plan.

          (b)  No Company nor any ERISA Affiliate of any Company has (i) engaged
     in, or is a successor or parent corporation to an entity that has engaged
     in, a transaction described in Sections 4069 or 4212(c) of ERISA or (ii)
     incurred, or reasonably expects to incur prior to the Closing Date, (A) any
     liability under Title IV of ERISA arising in connection with the
     termination of, or a complete or partial withdrawal from, any plan covered
     or previously covered by Title IV of ERISA or (B) any liability under
     Section 4971 of the Code that in either case could become a liability of
     that Company or any Company Group Subsidiary or Buyer or any of its ERISA
     Affiliates after the Closing Date.  No Employee Plan is a Multiemployer
     Plan or a Title IV Plan.
<PAGE>
 
          (c)  Each Employee Plan that is intended to be qualified under Section
     401(a) of the Code has been determined by the Internal Revenue Service to
     be so qualified and, to the knowledge of the Sellers, there has been no
     event since the date of such determination which would adversely affect
     such qualification; each trust created under any such Plan has been
     determined by the Internal Revenue Service to be exempt from tax under
     Section 501(a) of the Code and, to the knowledge of the Sellers, there has
     been no event since the date of such exemption which would adversely affect
     such exemption.  The Sellers have provided Buyer with the most recent
     determination letter of the Internal Revenue Service relating to each such
     Employee Plan.  Each Employee Plan has been maintained in substantial
     compliance with its terms and with the requirements prescribed by any and
     all applicable statutes, orders, rules and regulations, including but not
     limited to ERISA and the Code.

          (d)  Schedule 3.16 identifies each Benefit Arrangement.  The Sellers
                        ----                                                  
     have made available to Buyer copies or descriptions of each Benefit
     Arrangement (and, if applicable, related trust agreements) and all
     amendments thereto and written interpretations thereof.  Each Benefit
     Arrangement has been maintained in substantial compliance with its terms
     and with the requirements prescribed by any and all applicable statutes,
     orders, rules and regulations and has been maintained in good standing with
     applicable regulatory authorities.

          (e)  No member of the Company Group has any current or projected
     liability in respect of post-employment or post-retirement health or
     medical or life insurance benefits for retired, former or current employees
     of the Company Group, except as required to avoid excise tax under Section
     4980B of the Code.

          (f)  Except as would not reasonably be expected to have a Material
     Adverse Effect, all contributions, premiums or payments required to be made
     with respect to any Employee Plan have been made on or before their due
     date or accrued on the unaudited interim combined balance sheet as of
     January 31, 1998 of the Companies and the Company Group Subsidiaries and as
     a result, there are no underfunded amounts thereunder that have not been
     paid or accrued with respect to such Employee Plans.  No Employee Plan is
     currently subject to an audit or other investigation by the Internal
     Revenue Service, the Department of Labor, the PBGC or any other
     governmental or regulatory authority.  Except as would not reasonably be
     expected to have a Material Adverse Effect, no lawsuits, claims (other than
     routine claims for benefits) or complaints to, or by, any person or
     governmental entity have been filed or are pending and there are no facts
     or contemplated events which could be expected to give rise to any such
     lawsuit, claim or complaint with respect to any Employee Plan.

          Section 3.17.  Environmental Matters.  Except as disclosed on Schedule
     3.17 and except as to matters that would not reasonably be expected to have
     ----                                                                       
     a Material Adverse Effect:

          (a)  there has been no written environmental audit of any Property
     conducted within the past two years by the Sellers, or any member of the
     Company Group, which has not been made available to Buyer prior to the date
     hereof;

          (b)  no written notice, request for information, order, complaint or
     penalty has been received, and there are no judicial, administrative or
     other actions, suits, investigations or proceedings pending or threatened
     which allege a violation of any Environmental Law, in each case relating to
     any member of the Company Group arising out of any Environmental Law;

          (c)  each member of the Company Group has all environmental permits
     necessary for the operations of that member of the Company Group to comply
     with all applicable Environmental Laws and are in compliance with the terms
     of such permits and with all other applicable Environmental Laws; and

          (d)  no member of the Company Group has discharged, disposed of or
     released any Hazardous Substances on or at any of the Properties, other

     Jersey or Connecticut.

     disclosed in Schedule 3.18, no member of the Company Group is in violation
                           ----                                                
     of any applicable law, rule, regulation, judgment, injunction, order or
     decree, except for violations that have not had and would not reasonably be
     expected to have, individually or in the aggregate, a Material Adverse
     Effect.

          Section 3.19.  Rent Roll.  The rent roll attached hereto as Schedule

     percentage and breakpoint amount, current monthly rent, operating
     escalations, current past due amount, amount of security deposits is true,
     correct and accurate as of the date of such rent roll, except for any such
     inaccuracies which, individually or in the aggregate, would not be material
     with respect to the relevant Property.

          Section 3.20.  Disclosure Schedules.  (a) At Closing, the Sellers may
     revise the Schedules and Exhibit A to this Agreement by delivering revised
     Schedules or a revised Exhibit A to Buyer to reflect any matter hereafter
     arising or discovered which, if existing or known at the date hereof, would
     have been required to be set forth herein or described thereon (but no such
     revision shall relieve the Sellers of liability hereunder for breach of a
     representation or warranty except as provided in Section 11.04(c) or modify
                                                              --------          
     the representations and warranties for purposes of determining whether any
     condition to closing is satisfied).  Buyer shall be reasonably satisfied
     with any changes to Exhibit A that are inconsistent with the
     representations, warranties and covenants contained herein and that would
     materially adversely affect Buyer.  Any proposed revision to Exhibit A
     shall be provided to Buyer no later than five business days prior to
     Closing.

     (b)  The parties acknowledge and agree that (i) the Schedules to this
Agreement may include certain items and information solely for informational
purposes for the convenience of Buyer; (ii) the disclosure by the Sellers of any
matter in the Schedules shall not be deemed to constitute an acknowledgment by
the Sellers that the matter is required to be disclosed by the terms of this
Agreement or that the matter is material; and (iii) if any Schedule hereto
discloses information that is or may be properly disclosed on another Schedule
or Schedules, the matter shall be deemed to have been disclosed in such other
Schedule or Schedules.

     decision with respect to the execution, delivery and performance of this
     Agreement and the Escrow Agreement.  Buyer
<PAGE>
 
     acknowledges that the Sellers have given Buyer complete and open access to

     as expressly set forth in this Agreement, the Sellers make no
     representation or warranty with respect to (i) any projections, estimates
     or budgets delivered to or made available to Buyer of future revenues,
     future results of operations (or any component thereof), future cash flows
     or future financial condition (or any component thereof) of any member of
     the Company Group or the future business and operations of any member of
     the Company Group, (ii) any information or documents made available to
     Buyer or its advisors concerning the financial, physical or environmental
     condition of the Properties, the use to which the Properties may be put,
     the expenses of operation or maintenance of the Properties, the rental
     income or prospective rental income of the Properties, or anything else

     Sellers shall cause each member of the Company Group to conduct its
     businesses in the ordinary course consistent with past practices and to use
     commercially reasonable efforts to preserve intact its business
     organizations and relationships with third parties and to keep available
     the services of its present officers and employees.  Without limiting the
     generality of the foregoing, from the date hereof until the Closing Date,
     except as disclosed on Schedule 5.01 and except in connection with the
                                     ----                                  
     Restructuring, the Sellers will not permit any member of the Company Group
     to:

               (i)  adopt or propose any change in its certificate of
          incorporation, bylaws or other organizational documents;

               (ii)   merge or consolidate with any other Person or acquire the
          business or operations of any other Person;

               (iii)  sell or otherwise dispose of the Properties or any
          material portion thereof;

               (iv)   sell or otherwise dispose of any material assets or
          property (other than the Properties) except (A) pursuant to existing
          contracts or commitments that are listed on the Schedules hereto or

          improvement programs described on Schedule 5.01(a)(v) hereto; or
                                                     ----------           

               (vi)  agree or commit to do any of the foregoing.

     Except for actions taken in connection with the Restructuring and except
     for the transactions contemplated hereby, the Sellers will not take, and
     will not permit any member of the Company Group to take, any action that
     would make any representation or warranty of the Sellers hereunder
     inaccurate in any material respect at the Closing Date.

          (b)  Notwithstanding anything to the contrary contained herein, or in
     any budget with respect to any Property, subject to the requirements of
     Section 2.07, none of the Sellers nor any member of the Company Group will

     conditions at any Property disclosed in any engineering report or in any of
     other written information made available to Buyer on or prior to the date
     hereof during the period from the date hereof to the Closing Date.  If any
     such repairs, replacements or improvements are made by any member of the
     Company Group because such repairs, replacements or improvements (i) are
     required under legally binding agreements, (ii) are necessary to preserve
     the value of,  or prevent further deterioration to, the relevant Property
     or (iii) have been requested to be made by Buyer, then Buyer shall
     reimburse the Sellers at Closing for the actual cost of such repairs,
     replacements or improvements.

          Section 5.02.  Tenant Leases.  Notwithstanding anything to the
     contrary contained herein and except for actions taken in connection with
     the Restructuring and pursuant to Section 2.07, the Sellers agree that from

     the date hereof until the Closing Date:

          (a)  Without Buyer's consent, Sellers will not, and will not permit
     any member of the Company Group to, terminate any Tenant Lease, except by
     reason of a material default by the tenant thereunder or as required
     thereunder or by applicable law.  Buyer agrees that its consent under this

     and any member of the Company Group to cooperate with Buyer in its
     investigation of any member of the Company Group, except, in each case,
     where compliance by the Sellers with these provisions would result in the
     violation of a confidentiality restriction with a third-party or would
     jeopardize the availability of the attorney-client privilege to any member

                                                                       ----

     conduct any invasive tests or inspections or any tests for the presence of

     notwithstanding the foregoing, Buyer shall not have access to personnel
     records of the Company Group relating to individual performance or
     evaluation records, medical histories or other information which in the
     Sellers' good faith opinion is sensitive or the disclosure of which could
     subject the Company Group to risk of liability.

     to Buyer and its agents reasonable access to their books of account,
     financial and other records (including, without limitation, accountant's

     or useful for Buyer in connection with the performance of any of its
     obligations hereunder or in connection with any audit, investigation,
     dispute or litigation or any other reasonable business purpose relating to

     shall not unreasonably interfere with the conduct of the business of the
     Sellers. Buyer shall bear all of the out-of-pocket costs and expenses
     (including, without limitation, attorneys' fees, but excluding
     reimbursement for general overhead, salaries and employee benefits)
     reasonably incurred in connection with the foregoing.

          Section 5.04.  Notices of Certain Events.  The Sellers shall promptly
     notify Buyer of:

          (a)  any notice or other communication from any Person alleging that

     transactions contemplated by this Agreement;

          (b)  any notice or other communication from any governmental or
     regulatory agency or authority in connection with the transactions

     if pending on the date of this Agreement, would have been required to have
     been disclosed pursuant to Section 3.12.

     be reasonably satisfactory to Buyer, and shall ask such parties to execute
     and return such estoppel certificates to the appropriate member of the
     Company Group prior to the Closing.  The Sellers shall have no further
     obligation to obtain any such estoppel certificates, and the receipt of
     such estoppel certificates shall not be considered a condition to the
     closing of the transactions contemplated by this Agreement.

          If, prior to Closing, the Sellers receive any such estoppel
     certificates, the Sellers shall promptly deliver a copy of such estoppel
     certificates to Buyer.  If the facts set forth in any estoppel certificate

     counsel, at their own expense, separate from the counsel employed by Buyer.
     Whether or not the Sellers choose to defend 
<PAGE>
 
     or prosecute any claim, the parties hereto shall cooperate in the defense
     or prosecution thereof.

          (b)  Buyer shall promptly pay or cause to be paid to the Sellers all
     refunds of Taxes and interest thereon (to the extent in excess of the
     amount recorded in the Final Stockholders' Equity Amount) received by
     Buyer, any Affiliate of Buyer, any Company, or any Company Subsidiary
     attributable to Taxes imposed on the Sellers, any Company or any Company
     Subsidiary (or any predecessor or Affiliate of the Sellers) with respect to
     any Pre-Closing Tax Period.  The Sellers shall be subrogated to any rights
     of Buyer, any Company or any Company Subsidiary against third parties with
     respect to Taxes paid by any Seller or for which the Sellers otherwise are
     responsible under this Article 8.
                                    - 
          (c)  All transfer, documentary, sales, use, stamp, registration and
     similar taxes and fees (including any penalties and interest) incurred in
     connection with this Agreement and the transactions contemplated hereby
     shall be borne and paid by the Sellers and the Sellers will, at their own
     expense, file all necessary Returns and other documentation with respect to
     all such taxes and fees, and, if required by applicable law, Buyer will,
     and will cause its Affiliates to, join in the execution of any such Returns
     and other documentation.

          Section 8.04.  Termination of Existing Tax Sharing Agreements.  Any
     and all existing Tax sharing agreements between any Company and any member
     of the Seller Group (including, without limitation, the Tax Sharing
     Agreement) shall be terminated as of the close of business on the Closing
     Date.  After such date none of the Companies, the Company Subsidiaries, the
     Sellers nor any Affiliate of the Sellers shall have any further rights or
     liabilities thereunder. This Agreement shall be the sole Tax sharing
     agreement relating to any Company or any Company Subsidiary for all Pre-
     Closing Tax Periods.

          Section 8.05.  Tax Returns and Cooperation on Tax Matters.  (a) Buyer
     and the Sellers agree to furnish or cause to be furnished to each other,
     upon request, as promptly as practicable, such information (including
     access to books and records) and assistance (including making its employees
     available on a mutually convenient basis) relating to the Companies and the
     Company Subsidiaries as is reasonably necessary for any determination with
     respect to Taxes, including the filing of any Return, the preparation for
     any audit, and the prosecution or defense of any claim, suit or proceeding
     relating to Taxes.  Buyer and the Sellers agree to retain or cause to be
     retained all books and records pertinent to the Companies and the Company
     Subsidiaries until the applicable period for assessment under applicable
     law (giving effect to any and all extensions or waivers) has expired, and
     to abide by or cause the abidance with all record retention agreements
     entered into with any Taxing Authority. Buyer agrees to give the Sellers
     reasonable notice prior to discarding or destroying any such books and
     records relating to Tax matters and, if the Sellers so request, Buyer shall
     allow the Sellers to take possession of such books and records.  Buyer and
     the Sellers shall cooperate with each other in the conduct of any audit or
     other proceedings involving the Seller Group for any Tax purposes and each
     shall execute and deliver such powers of attorney and other documents as
     are necessary to carry out the intent of this subsection.  Any information
     obtained pursuant to Section 8.05 shall be kept confidential, except as may
                                  ----                                          
     be otherwise necessary in connection with the filing of Returns or claims
     for refund or in conducting an audit or other proceeding.

          (b)  Buyer shall prepare and timely file or cause the Companies and
     the Company Subsidiaries to prepare and timely file all Returns relating to
     the Companies and any of the Company Subsidiaries that are due (taking into
     account any applicable extension period) after the Closing Date.  Returns
     required to be filed by Buyer in respect of a Pre-Closing Period shall be
     prepared on a basis consistent with those prepared for prior tax 
<PAGE>
 
     years unless a different treatment of any item is required by an
     intervening change in law. Buyer shall furnish the Sellers (and their
     representatives) with a copy of any Return prepared by it for a Pre-Closing
     Period at least 20 business days before the anticipated filing date thereof
     and, in preparing such Return, shall accept any comments made by the
     Sellers with respect to any issue or item which could give rise to a claim
     for indemnification; provided that this sentence shall not apply in respect
     of any comments for which the Sellers do not provide Buyer, if so requested
     in writing to do so, with an opinion of counsel to the effect that there is
     a reasonable basis for the Sellers' comments.

          Section 8.06.  Indemnification by Seller.  (a) The Sellers hereby
     indemnify Buyer against and agree to hold it harmless from any (i) Tax
     imposed on any Company or any Company Subsidiary and (ii) out-of-pocket
     costs and expenses (including, without limitation, reasonable expenses of
     investigation and attorneys' fees and expenses), arising out of or incident
     to the imposition, assessment or assertion of any Tax indemnified under
     Section 8.06(a)(i), in each case with respect to any Pre-Closing Tax Period
             ----------                                                         
     and in each case incurred or suffered by Buyer, any of its Affiliates or,
     effective for any Post-Closing Tax Period, any Company, or any Company
     Subsidiary (the sum of 8.06(a)(i) and 8.06(a)(ii) being referred to as a
                            ----------     -----------                       
     "LOSS"); provided that the Sellers shall have no liability for the payment
     of any Loss attributable to or resulting from (i) any action described in
     Section 8.03(a) hereof relating to any breach by Buyer, or its Affiliates
             -------                                                          
     of an obligation under this Agreement, (ii) any transaction occurring after
     the close of business on the Closing Date or (iii) a reduction in any Tax
     Asset of any member of the Seller Group which would otherwise be available
     to the Buyer for a Post-Closing Tax Period;  provided further, that the
     Sellers shall have no obligation to make any payment to Buyer pursuant to
     this Section 8.06(a) until the amount of all claims arising pursuant hereto
                  ----                                                          
     in the aggregate exceeds the Basket, in which case Buyer shall be entitled
     to indemnity for the full amount of all claims in excess of the Basket.

          (b)  Any Taxes for a Tax Period beginning before the Closing Date and
     ending after the Closing Date (a "STRADDLE PERIOD") shall be apportioned
     between the Pre-Closing Tax Period and the Post-Closing Tax Period on the
     basis of the actual operation of the Companies and the Company
     Subsidiaries.  Each such Pre-Closing Tax Period and Post-Closing Tax Period
     shall be deemed to be a Tax Period subject to the provisions of Article 8.
                                                                             - 
          (c)  If as a result of an adjustment the Sellers make a payment to any
     Taxing Authority in respect of a Tax of any member of the Seller Group with
     respect to any Pre-Closing Tax Period, then Buyer shall promptly pay to the
     Sellers an amount equal to such payment made by the Sellers, provided, that
     any such payment by Buyer shall not exceed an amount equal to the positive
     balance, if any, in the Basket.

          (d)  The Basket shall be reduced by (i) the amount of any claim of
     Buyer under Section 8.06(a) hereof that is not paid in whole or part by the
                         -------                                                
     Sellers solely by reason of there being a positive balance in the Basket,
     and (ii) the amount of any payment of Buyer to the Sellers under Section
     8.06(c) hereof.
     -------        

          (e)  Any payment by the Sellers pursuant to this Section 8.06 shall be
                                                                   ----         
     made not later than 30 business days after receipt by the Sellers of
     written notice from Buyer stating that any Loss has been paid by Buyer, any
     of its Affiliates or, effective upon the Closing, any Company or any
     Company Subsidiary and the amount thereof and of the indemnity payment
     requested; provided that the Sellers shall not be required to make any
     payment hereunder earlier than five days before it is due to the
     appropriate Taxing Authority.  In the case of a Tax that is contested in
     accordance with the provisions of Section 8.06(f), payment of such Tax to
                                               -------                        
     the appropriate Taxing Authority shall not be considered due earlier than
     the date of Final Determination with respect to such Tax.
<PAGE>
 
          (f)  If any claim or demand for Taxes in respect of which indemnity
     may be sought pursuant to this Section 8.06 is asserted in writing against
                                            ----                               
     Buyer, any of its Affiliates or, effective upon the Closing, any Company or
     Company Subsidiary, Buyer shall notify the Sellers of such claim or demand
     within 10 business days of receipt thereof, or such earlier time that would
     allow the Sellers to timely respond to such claim or demand (but no failure
     to so notify Sellers shall preclude indemnification hereunder except to the
     extent Sellers were prejudiced by such failure), and shall give the Sellers
     such information with respect thereto as the Sellers may reasonably
     request. The Sellers may discharge, at any time, their indemnification
     obligation under this Section 8.06 by paying to Buyer the amount of the
                                   ----                                     
     applicable Loss, calculated on the date of such payment.  The Sellers may,
     at their own expense, participate in and, upon notice to Buyer, assume and
     control the defense of any such claim, suit, action, litigation or other
     proceeding (including any Tax audit, other than a claim under Section
     8.06(i), in which event Sellers may, at their own expense, participate in
     the defense of such claim).  Buyer shall empower by appropriate powers of
     attorney such persons as may be designated by the Sellers from time to time
     as its representatives in any such proceeding.  If the Sellers assume such
     defense, Buyer shall have the right (but not the duty) to participate in
     the defense thereof and to employ counsel, at its own expense, separate
     from the counsel employed by the Sellers. Whether or not the Sellers choose
     to defend or prosecute any claim, Buyer shall use reasonable efforts to
     mitigate any Loss and all of the parties hereto shall cooperate in the
     defense or prosecution thereof.

          (g)  The Sellers shall not be liable under this Section 8.06 for (i)
                                                                  ----        
     any settlements effected, without the Sellers' prior written consent;
     provided that the Sellers have not affirmatively abandoned the contest of
     any such Tax or (ii) or resulting from any claim, suit, action, litigation
     or proceeding in which the Sellers were not permitted an opportunity to
     participate.

          (h)  Any amount paid to or by the Sellers in respect of warranties or
     indemnities under this Agreement or the Related Agreements shall be treated
     as an adjustment to the Purchase Price.

          (i)  Prior to the Closing, the Sellers shall cause KPMG Peat Marwick
     to prepare a report (which shall be reasonably acceptable to Buyer) setting
     forth the current and accumulated earnings and profits, if any, of the
     Company Group (the "E&P REPORT").  The cost of preparing the E&P Report
     shall be borne by the Sellers.  As part of the Restructuring, the Sellers
     shall take such actions as are reasonably necessary to ensure that the
     combined earnings and profits of the Companies accumulated for all Tax
     Periods through and including the Tax Period ending at the close of
     business on the Closing Date (disregarding any Company having net negative
     accumulated earnings and profits) will be not more than $5,000,000 (reduced
     by any earnings and profits of a Company Subsidiary attributable to a Tax
     Period in which such Company Subsidiary was not a member of the Company
     Group, whether or not such Company Subsidiary is a subsidiary of a Company
     having negative earnings and profits).  The Sellers hereby indemnify Buyer
     and General Growth Properties, Inc. ("GGPI"), which shall be a third party
     hereof notwithstanding Section 13.05, against any Taxes imposed on Buyer,
                                    -----                                     
     GGPI, any  Affiliates of GGPI or any Company or Company Subsidiary as a
     result of the combined earnings and profits of the Companies accumulated
     for all Tax Periods through and including the Tax Period ending at the
     close of business on the Closing Date (disregarding any Company having net
     negative accumulated earnings and profits) exceeding $5,000,000 (reduced by
     any earnings and profits of a Company Subsidiary attributable to a Tax
     Period in which such Company Subsidiary was not a member of the Company
     Group, whether or not such Company Subsidiary is a subsidiary of a Company
     having negative earnings and profits).  In no event, however, shall the
     Sellers' liability under this Section 8.06(i) and Section 8.02(xii) exceed
                                           -------                             
     $25,000,000.

          (j)  This Article 8 shall be the sole provision governing Tax matters
                            -                                                  
     and indemnities therefor under this Agreement, except as and to the extent
     provided in Section 11.06.
                         -----

          Section 8.07.  Survival.  Notwithstanding anything in this Agreement
     to the contrary, the provisions of this Article shall survive for thirty
     days following the full period of all statutes of limitations (giving
     effect to any waiver, mitigation or extension thereof).

          Section 8.08.  Withholding.  On or prior to Closing, the Sellers shall
     submit an application for a withholding tax certificate and shall provide
     Buyer with notice thereof, as provided for in Treasury regulation
     (S)1.1445-1(c)(2)(i)(b).  Buyer shall withhold 10% of the Purchase Price
     allocated to the Shares hereunder, as paid from time to time, pursuant to
     Section 1445 of the Code and deposit such amount in an interest-bearing
     escrow account to be established by the Sellers and Buyer with a financial
     institution designated by the Sellers. On the 20th day following receipt of
     a final determination by the Internal Revenue Service with respect to the
     Seller's application for the withholding tax certificate, the amount of
     such escrow account shall be distributed as follows: (i) to the Internal
     Revenue Service, an amount equal to the amount set forth in such final
     determination; and (ii) to the Sellers, an amount equal to the balance of
     the escrow account (including any accrued interest) after the distribution
     provided for in (i) above.

          Section 9.01.  Employment of Company Group Employees; Service
     Recognition.  (a) Buyer or its Affiliates may, but shall not be obligated
     to, offer to employ any or all employees of the Company Group ("EMPLOYEES")
     on such terms as it deems advisable. The Sellers shall cause all Employees
     of the Company Group to be terminated immediately prior to the Closing

     employed by Buyer or its Affiliates following Closing,  recognize service
     with the Sellers, the Company Group and their Affiliates as service for all
     purposes under any benefit plan maintained by Buyer or its Affiliates in
     which such Employees are otherwise eligible to participate, except for
     purposes of benefit accrual under any defined benefit pension plan.  Buyer
     and its Affiliates shall credit the dollar amount of all expenses incurred
     by such Employees and their respective eligible dependents during the
     applicable plan year in which occurs the Closing Date, to the extent
     relevant, for purposes of satisfying such plan year's deductible and co-
     payment limitations under any applicable plan in which such Employees
     participate after the Closing Date.

          (c)  Notwithstanding the foregoing, this Section 9.01 shall not apply

     to any Employee included in a unit of employees covered by a collective
     bargaining agreement.

          Section 9.02.  Stay Sell Agreement.  (a) Notwithstanding any

     and shall hold the Sellers and their Affiliates harmless from, all
     liability for "Severance Pay", within the meaning of the Stay Sell
     Agreements or any other severance plan or policy of any Company, with
     respect to any Employee who is employed by Buyer or its Affiliates in any
     capacity at any time during the period commencing on the 30th day after the
     Closing Date and ending on the second anniversary of the Closing Date (a
     "RETAINED EMPLOYEE").  On or prior to the 30th day after the Closing Date,
     Buyer shall provide Parent with a written list of those Employees 
<PAGE>
 
     covered by the Stay Sell Agreements who Buyer does not intend to treat as a
     Retained Employee.

          (b)  Except as provided in paragraph 9.02(a) of this Section, Parent
                                               -------

     Employee's annual bonus and vacation pay, if any, earned through the
     Closing Date for the calendar year in which the Closing Date occurs shall
     be calculated by the Sellers as soon as practicable after the Closing Date,
     and reflected as a liability on the Closing Balance Sheet.

          Section 9.04.  No Third-Party Beneficiaries.  The provisions of this
     Article shall not create any rights in any Employee or any other person who
     is not a party to this Agreement, and no such person shall have any rights
     as a third party beneficiary hereof.

     possession of the leased premises to which the Lien relates or have filed
     for bankruptcy, in each case as of the Closing Date, or (v) arising out of

     reserve to be established on the Closing Balance Sheet in respect of such
     litigation matters shall be $40,000 and (ii) Buyer and its Affiliates shall
     undertake the defense of the same.  Buyer and its Affiliates may not make

     such litigation matter without the prior written consent of Parent, which
     shall not be unreasonably withheld.

          (c)  From and after Closing, Buyer hereby indemnifies the Sellers and
     their Affiliates against and agrees to hold each of them harmless from any
     and all Damages incurred or suffered by the Sellers or any of their

     of such excess and (ii) Buyer's maximum aggregate liability under this
     Section 11.02(c) shall not exceed $50,000,000.
             --------                              

          Section 11.03.  Procedures.  (a) The party seeking indemnification
     under Section 11.02 (the "INDEMNIFIED PARTY") agrees to give prompt notice
                   -----                                                       
     to the party against whom indemnity is sought (the "INDEMNIFYING PARTY") of
     the assertion of any claim, or the commencement of any suit, action or
     proceeding ("CLAIM") in respect of which indemnity may be sought under such
     Section and will provide the Indemnifying Party such information with
     respect thereto that the Indemnifying Party may reasonably request. The
     failure to so notify the Indemnifying Party shall not relieve the
     Indemnifying Party of its obligations hereunder, except to the extent such
     failure shall have adversely prejudiced the Indemnifying Party.

          (b)  The Indemnifying Party shall be entitled to participate in the
     defense of any Claim asserted by any third party ("THIRD PARTY CLAIM") and,
     subject to the limitations set forth in this Section, shall be entitled to
     control and appoint lead counsel (who shall be reasonably acceptable to the
     Indemnified Party) for such defense, in each case at its expense.

          (c)  If the Indemnifying Party shall assume the control of  the
     defense of any Third Party Claim in accordance with the provisions of this
     Section, (i) the Indemnifying Party shall obtain the prior written consent
     of the Indemnified Party (which shall not be unreasonably withheld) before
     entering into any settlement of  such Third Party Claim or consenting to
     entry of any judgment and (ii) the Indemnified Party shall be entitled to
     participate in the defense of such Third Party Claim and to employ separate
     counsel of its choice for such purpose.  The fees and expenses of such
     separate counsel shall be paid by the Indemnified Party, except that if the
     Indemnifying Party has a conflict of interest with respect to any Third
     Party Claim, the Indemnifying Party shall pay the fees and expenses of such
     separate counsel for the Indemnified Party.

          (d)  If the Indemnifying Party shall fail to timely undertake the
     defense of any Third Party Claim in accordance with the provisions of this
     Section and notify the Indemnified Party thereof, the Indemnified Party
     may, but shall not be obligated to, undertake the defense of the same and
     make any compromise or settlement thereof and recover the entire cost
     thereof from the Indemnifying Party, including without limitation
<PAGE>
 
     reasonable attorneys' and expert's fees (but the Indemnified Party shall
     not have the right to make any compromise or settlement of, or consent to
     the entry of judgment in, any such Third Party Claim without the prior
     written consent of the Indemnifying Party, which shall not be unreasonably
     withheld).

          (e)  Each party shall cooperate, and cause their respective Affiliates
     to cooperate, in the defense or prosecution of any Third Party Claim and
     shall furnish or cause to be furnished such records, information and
     testimony, and attend such conferences, discovery proceedings, hearings,
     trials or appeals, as may be reasonably requested in connection therewith.

          Section 11.04.  Calculation of Damages.  (a) The amount of any Damages
     payable under Section 11.02 by the Indemnifying Party shall be net of   any
                           -----                                                
     amounts recovered or recoverable by the Indemnified Party under applicable
     insurance policies.

          (b)  The Indemnifying Party shall not be liable under Section 11.02
                                                                        -----
     for any (i) Damages relating to any matter to the extent that (A) there is
     included in the Closing Balance Sheet a specific liability or reserve
     relating to such matter or (B) the Indemnified Party had otherwise been
     compensated for such matter pursuant to the Purchase Price adjustment under
     Section 2.05 or (ii) consequential or punitive Damages.  Any calculation of
             ----                                                               
     lost profits shall not include a capitalization rate or other earnings
     multiplier.

          (c)  Notwithstanding any other provision of this Agreement to the
     contrary, if on the Closing Date the Indemnified Party has actual knowledge
     of any information that would cause one or more of the representations and
     warranties made by the Indemnifying Party to be inaccurate as of the date
     made (other than those contained in Section 8.02(viii) and (xi), the
                                                 ----                    
     Indemnified Party shall have no right or remedy after the Closing with
     respect to such inaccuracy to the extent of the Indemnified Party's actual
     knowledge thereof and shall be deemed to have waived its rights to
     indemnification in respect thereof.

          Section 11.05.  Assignment of Claims.  If the Indemnified Party
     receives any payment from an Indemnifying Party in respect of any Damages
     pursuant to Section 11.02 and the Indemnified Party could have recovered
                         -----                                               
     all or a part of such Damages from a third party (a "POTENTIAL
     CONTRIBUTOR") based on the underlying Claim asserted against the
     Indemnifying Party, the Indemnified Party shall assign such of its rights
     to proceed against the Potential Contributor as are necessary to permit the
     Indemnifying Party to recover from the Potential Contributor the amount of
     such payment; provided that the Indemnified Party shall not be required to
     assign any right to proceed against a Potential Contributor if the
     Indemnified Party determines in its reasonable discretion that such
     assignment would be materially detrimental to its reputation or future
     business prospects.

          Section 11.06.  Exclusivity.  Except as specifically set forth in this
     Agreement, Buyer waives any rights and claims Buyer may have against the
     Sellers, whether in law or in equity, relating to any of the Companies or
     the Shares or the transactions contemplated hereby (other than claims for
     fraud).  The rights and claims waived by Buyer include, without limitation,
     claims for contribution or other rights of recovery arising out of or
     relating to any Environmental Law, claims for breach of contract, breach of
     representation or warranty, negligent misrepresentation and all other
     claims for breach of duty (other than claims for breach of this Agreement
     or representations or warranties expressly set forth in this Agreement).
     After the Closing, Sections 8.06 and 11.02 will provide the exclusive
                                 ----     -----                           
     remedy (other than equitable remedies and other than a claim at law for
     breach of representation, warranty, or covenant contained in Section
     8.02(viii), 8.02(xi), 8.03, 8.04, 8.05 or 8.08) for any misrepresentation,

     terminated at any time prior to the Closing:

               (a)  by mutual written agreement of the Sellers and Buyer;

               (b)  by Buyer, if on or before 5:00 p.m. New York City time on

          satisfied with the disclosure schedules and Exhibit A attached hereto.

          been consummated on or before June 30, 1998; or

               (d)  by either the Sellers or Buyer if consummation of the

          order, decree or judgment of any court or governmental body having
          competent jurisdiction.

     The party desiring to terminate this Agreement pursuant to Sections
     12.01(b), 12.01(c) or 12.01(d) shall give notice of such termination to the

     liability of either party (or any stockholder, director, officer, employee,

     performance of the obligations of the other party, (ii) failure to perform
     a material covenant of this Agreement or (iii) breach by either party
     hereto of any representation or warranty or material agreement contained

          Section 13.15.  Specific Performance.  The Sellers acknowledge that a
     failure by the Sellers to close the transactions contemplated by this

          (i) At the Effective Time, (A) the Buyer will, or will cause the
     Surviving Corporation to, furnish to the paying agent engaged for purposes
     of this Agreement (the "Paying Agent") a corpus consisting of cash which,
     together with the amount to be delivered by the Deposit Escrow Agent
     pursuant to (S) 2(h)(ii)(a), is sufficient in the aggregate for the Paying
     Agent to make full payment of the Stockholder Allocable Portion of the
     Merger Consideration to the holders of all of the outstanding Company
     Shares (other than any Dissenting Shares and less the applicable Post-
     Closing Escrow Amount to be paid to the Post-Closing Escrow Agent and less
     amounts to be withheld and paid to the Internal Revenue Service pursuant to
     (S)2(j), or deposited with the Post-Closing Escrow Agent pursuant to
     (S)2(j)) (the "Payment Fund"), and (B) the Buyer will cause the Paying
     Agent to mail a letter of transmittal (with instruction for its use), which
     shall specify that delivery shall be effected, and risk of loss and title
     to the Certificates shall pass, only upon proper delivery of such
     Certificates to the Paying Agent, in the form attached hereto as Exhibit E
     to each record holder of outstanding Company Shares for the holder to use
     in surrendering the Certificates which represented such holder's Company
     Shares against payment of such holder's Stockholder's Portion of the Merger
     Consideration (less, in the case of each Schedule I Stockholder, the
     amounts thereof to be paid to the Post-Closing Escrow Agent as part of the
     Post-Closing Escrow Amount and any applicable Escrow Withholding Amount,
     and less any amounts to be withheld and paid to the Internal Revenue
     Service pursuant to (S)2(j) and, in the case of other Company Stockholders,
     amounts to be withheld pursuant to (S) 2(j)).  Each holder of Certificates
     theretofore evidencing Company Shares, upon proper surrender thereof to the
     Paying Agent together with and in accordance with such transmittal form and
     any other documents required thereby, shall, subject to (S) 2(j), be
     entitled to receive in exchange therefore such holder's Stockholder's
     Portion of the Merger Consideration deliverable in respect of the Company
     Shares theretofore evidenced by the Certificates so surrendered (less, in
     the case of each Schedule I Stockholder, the amounts thereof to be paid to
     the Escrow Agent as part of the Post-Closing Escrow Amount and any
     applicable Escrow Withholding Amount, and less any amounts to be withheld
     and paid to the Internal Revenue Service pursuant to (S)2(j) and, in the
     case of other Company

                                      -14-
<PAGE>
 
     Stockholders, amounts to be withheld pursuant to (S) 2(j)).  Upon such
     proper surrender, the Paying Agent shall, subject to (S) 2(j), promptly
     deliver such holder's Stockholder's Portion of the Merger Consideration to
     the relevant Company Stockholder (less, in the case of each Schedule I
     Stockholder, the amounts thereof to be paid to the Post-Closing Escrow
     Agent as part of the Post-Closing Escrow Amount and any applicable Escrow
     Withholding Amount, and less any amounts to be withheld and paid to the
     Internal Revenue Service pursuant to (S)2(j) and, in the case of other
     Company Stockholders, amounts to be withheld pursuant to (S) 2(j)).  Until
     properly surrendered, Certificates formerly evidencing Company Shares shall
     be deemed for all purposes to evidence only the right to receive the
     applicable portion of the Merger Consideration as herein provided and
     subject to (S)(S) 2(i) and (j).  No interest shall accrue or be paid on any
     cash payment upon surrender of Certificates which immediately prior to the
     Effective Time represented Company Shares.  In the event of a permitted
     transfer of ownership of Company Shares, which is not registered in the
     transfer records of the Company, the applicable Stockholder's Portion of
     the Merger Consideration or portion thereof (less the applicable portion of
     the Post-Closing Escrow Amount and any applicable Escrow Withholding
     Amount, and less any amounts to be withheld and paid to the Internal
     Revenue Service pursuant to (S)2(j), in the case of Schedule I Stockholders
     and, in the case of the other Company Stockholders, amounts to be withheld
     pursuant to (S) 2(j)) may be paid to a transferee of a Certificate if such
     Certificate is presented to the Paying Agent accompanied by all documents
     required to evidence and effect such transfer and any evidence that any
     applicable stock transfer Taxes have been paid.  Notwithstanding the
     foregoing, the Buyer will, if and to the extent requested by the Company or
     any Company Stockholder not less than three (3) Business Days prior to the
     Closing Date, make appropriate arrangements, subject to (S) 2(j), with the
     Paying Agent to enable the Stockholder's Portion of the Merger
     Consideration payable to any Company Stockholder (less, in the case of each
     Schedule I Stockholder, the amount thereof to be paid to the Post-Closing
     Escrow Agent as part of the Post-Closing Escrow Amount and any applicable
     Escrow Withholding Amount, and less any amounts to be withheld and paid to
     the Internal Revenue Service pursuant to (S) 2(j) and, in the case of the
     other Company Stockholders, amounts to be withheld pursuant to (S) 2(j)),
     to be paid on the Effective Date (including payment by wire transfer of
     immediately available funds), upon surrender of the Certificates evidencing
     such Company Stockholder's Company Shares and such other documents as may
     be required by the Paying Agent.

          (ii) The Buyer may cause the Paying Agent to invest the cash included
     in the Payment Fund, to the extent such cash is not disbursed on the
     Effective Date, in certificates of deposit or money market funds; provided,
     however, that the terms and conditions of the investments shall be such as
     to permit the Paying Agent to make, subject to (S)(S) 2(i) and (j), prompt
     payment of the applicable portion of the Stockholder Allocable Portion of
     the Merger Consideration included in the Payment Fund as necessary. The
     Buyer may cause the Paying Agent to pay over to the Surviving Corporation
     any net earnings with respect to the investments, and the Buyer will cause

                                      -15-
<PAGE>
 
     the Surviving Corporation to replace promptly any portion of the Payment
     Fund which the Paying Agent loses through investments.

          (iii)  The Buyer may cause the Paying Agent to pay over to the
     Surviving Corporation any portion of the Payment Fund (including any
     earnings thereon) remaining 180 days after the Effective Time, and
     thereafter all former Company Stockholders shall only be entitled to look
     to the Surviving Corporation (subject to abandoned property, escheat and
     other similar laws) as general creditors thereof with respect to the Merger
     Consideration payable upon surrender of their Certificates.  The Buyer and
     the Surviving Corporation shall not be liable to any holder of Certificates
     for any cash payable in respect thereof delivered to a public official
     pursuant to any applicable abandoned property, escheat or similar law.

          (iv) The Buyer shall cause the Surviving Corporation to pay all
     charges and expenses of the Paying Agent.

     (f) Closing of Transfer Records.  From and after the Effective Time, the
     stock transfer books of the Company shall be closed and no transfers of
     Company Shares outstanding prior to the Effective Time shall be made on the
     stock transfer books of the Surviving Corporation.

     (g) Dissenters' Rights.  No Dissenting Stockholder shall be entitled to
     such Dissenting Stockholder's Stockholder's Portion of the Merger
     Consideration unless and until such Dissenting Stockholder shall have
     failed to perfect or shall have effectively withdrawn or lost such holder's
     right to dissent from the Merger under the Delaware General Corporation
     Law, and any Dissenting Stockholder shall be entitled to receive only the
     payment provided by Section 262 of the Delaware General Corporation Law
     with respect to Company Shares owned by such Dissenting Stockholder.  If
     any Person who otherwise would be deemed a Dissenting Stockholder shall
     have failed to properly perfect or shall have effectively withdrawn or lost
     the right to dissent with respect to any Company Shares, such Company
     Shares shall, subject to (S) 2(j), thereupon be treated as though such
     Company Shares had been converted into the applicable portion of the Merger
     Consideration pursuant to (S) 2(d)(vi) hereof.  The Company shall give the
     Buyer (i) prompt notice of any written demands for appraisal, attempted
     withdrawals of such demands and any other instruments served pursuant to
     applicable law received by the Company relating to stockholders' rights of
     appraisal and (ii) the opportunity to direct all negotiations and
     proceedings with respect to demand for appraisal under the Delaware General
     Corporation Law.  The Company shall not, except with the prior written
     consent of the Buyer, voluntarily make any payment with respect to any
     demands for appraisals of Dissenting Shares, offer to settle or settle any
     such demands or approve any withdrawal of any such demands.

     the provisions of the Deposit Escrow Agreement.

          (ii)  In accordance with and subject to the terms of the Deposit

               (a) If the Closing occurs, at the Closing, the Deposit Escrow
     Agent shall deliver the Deposit, together with all interest earned thereon,
     if any, to the Paying Agent.

               (b) If this Agreement terminates in accordance with its terms by
     reason of the Buyer's or the Transitory Subsidiary's default and a notice
     of termination has been delivered to the Buyer, the Deposit Escrow Agent
     shall deliver the Deposit, together with all interest earned thereon, if

(10%) of the sum of (x) the aggregate Stockholder's Portions of the Merger
Consideration allocable to the Company Stockholders who or which are foreign
persons for purposes of Section 1445 of the Code, and

                                      -17-
<PAGE>
 
(y) the aggregate portions of the Closing Expense Fund allocable to such Company
Stockholders (such aggregate ten percent (10%) withheld amount being referred to
as the "Withholding Amount"), together with the applicable Internal Revenue
Service forms (as duly prepared and executed by the Buyer), which shall specify
the portion of the Withholding Amount allocable to each Company Stockholder with
respect to whom or which the Buyer has withheld under this (S)2(j).  If the
Buyer is required pursuant to (S)2(k) to pay the Adjustment to the
Representative, on behalf of the Company Stockholders, the Buyer will, subject
to (S)2(j)(ii) hereof, at the time when the Buyer is required to so pay the
Adjustment, withhold and promptly pay over to the Internal Revenue Service ten

applicable Internal Revenue Service forms (as duly prepared and executed by the
Buyer), which shall specify the portion of the Adjustment Withholding Amount
allocable to each such Company Stockholder with respect to whom or which the
Buyer has withheld under this (S)2(j).  Promptly after filing with the Internal
Revenue Service, the Buyer will deliver to the Representative a copy of all
Internal Revenue Service forms filed by the Buyer in accordance with this
(S)2(j). The Buyer will not withhold under this (S)2(j) any portion of a
Stockholder's Portion of the Merger Consideration, any portion of the Closing
Expense Fund, or any portion of the Adjustment, allocable to any Company
Stockholder who or which furnishes to the Buyer on or before the Closing a
certificate in the form attached hereto as Exhibit I certifying that such
Company Stockholder is not a "foreign person" within the meaning of Section 1445
of the Code.  If a Company Stockholder does not furnish such certificate to the
Buyer, it shall be assumed that such Company Stockholder is a "foreign person".
                                                     
          (ii)  If a Schedule I Stockholder who or which is a "foreign person"
for purposes of Section 1445 of the Code applies for a withholding certificate
from the Internal Revenue Service to authorize reduced withholding (including
zero withholding) under Section 1445 of the Code (a "Withholding Certificate")
on or before the Closing, such Schedule I Stockholder shall submit to the Buyer
on or before the Closing a notice under Treasury Regulations Section 1.1445-
1(c)(2) substantially in the form of Exhibit J attached hereto.  In this event,
the Buyer shall deposit with the Post-Closing Escrow Agent an amount equal to
ten percent (10%) of the sum of (x) such Schedule I Stockholder's Stockholder's
Portion of the Merger Consideration, and (y) the portion of the Closing Expense
Fund allocable to such Company Stockholder (such ten percent (10%) deposited
amount being referred to as the "Escrow Withholding Amount"), in accordance with
this (S)2(j). The Post-Closing Escrow Agent shall hold the Escrow Withholding
Amount with respect to such Schedule I Stockholder until the earlier to occur of
(x) receipt by the Post-Closing Escrow Agent of a copy of a Withholding
Certificate or notice of denial ("Notice of Denial") from the Internal Revenue
Service with respect to such Schedule I Stockholder (which copy shall be
delivered to the Post-Closing Escrow Agent by the Buyer, promptly upon receipt
of such copy by the Buyer from the Internal Revenue Service, and may be
delivered to the Post-Closing Escrow Agent by such Schedule I Stockholder), or
(y) the date (the "Expiration Date") which is twelve (12) months following the
Closing Date. The Post-Closing Escrow Agent shall pay the Escrow Withholding
Amount with respect to such Schedule

                                      -18-
<PAGE>
 
I Stockholder (or a portion thereof) within twenty (20) days following the
mailing by the Internal Revenue Service of a Withholding Certificate or Notice
of Denial (or copy thereof) with respect to such Schedule I Stockholder (but not
less than five (5) days from receipt of such Withholding Certificate or Notice
of Denial or copy thereof), as follows.  In the event the Internal Revenue
Service issues a Withholding Certificate eliminating the withholding tax under
Section 1445 of the Code with respect to such Schedule I Stockholder, the Post-
Closing Escrow Agent (v) shall pay such Escrow Withholding Amount, together with
all interest earned thereon, directly to such Schedule I Stockholder, and (w)
shall send to the Buyer a copy of the check payable to the order of such
Schedule I Stockholder in the amount of such Escrow Withholding Amount.  In the
event the Internal Revenue Service denies the Schedule I Stockholder's
application for a Withholding Certificate, or issues a Withholding Certificate
with respect to such Schedule I Stockholder providing for an amount of
withholding that is less than such Escrow Withholding Amount, upon receipt of
any executed applicable Internal Revenue Service forms from the Buyer, the Post-
Closing Escrow Agent promptly (x) shall pay to the Internal Revenue Service such
Escrow Withholding Amount, or portion thereof, plus interest thereon (if any),
as set forth in the Notice of Denial or Withholding Certificate with respect to
such Schedule I Stockholder, together with the applicable Internal Revenue
Service forms received from the Buyer (which Internal Revenue Service forms the

plus interest (if any), and (z) shall send to the Buyer a copy of the check

Amount to the Internal Revenue Service for the account of such Schedule I
Stockholder, together with the applicable Internal Revenue Service forms

          (i) No later than five (5) days prior to the Closing, the Company
shall prepare and deliver to the Buyer a preliminary pro forma consolidated
statement of Net Quick Assets (as defined below) of (a) the Company and its
Subsidiaries (excluding the Venture) and (b) the Venture, in each case, as of
the Closing Date, assuming the consummation of the transactions

                                      -19-
<PAGE>
 
contemplated hereby and by the P City Agreement, prepared in accordance with the
terms of this (S) 2(k) (the "Preliminary Net Quick Asset Schedules").  No later
than ninety (90) days after the Closing Date, the Buyer shall cause to be
prepared and delivered to the Representative an unaudited consolidated statement
of Net Quick Assets of (x) the Company and its Subsidiaries (excluding the
Venture) and (y) the Venture as of the Closing Date and following the
consummation of the transactions contemplated hereby and by the P City
Agreement, prepared in accordance with the terms of this (S) 2(k) (the "Closing
Net Quick Asset Schedules").  The Preliminary Net Quick Asset Schedules and the
Closing Net Quick Asset Schedules shall reflect only the following categories of
assets, which categories are referred to in the Financial Statements for the
year ended December 31, 1997:  "Cash and Cash Equivalents", "Accounts
Receivable", and "Prepaid expenses and other assets," in the case of the Company
and its Subsidiaries (excluding the Venture) and "Cash and Cash Equivalents",
"Accounts Receivable" and "Prepaid expenses, in the case of the Venture
(collectively, the "Quick Assets") and shall reflect only the following
categories of liabilities, which categories are referred to in the Financial
Statements for the year ended December 31, 1997, "Accounts payable and accrued
expenses", "Accrued real estate taxes" and "Tenant liabilities", in the case of
the Company and its Subsidiaries (excluding the Venture), and "Accounts payable
and accrued expenses" and "Tenant liabilities", in the case of the Venture
(collectively, the "Quick Liabilities"), provided that, as described above, the
Quick Assets and Quick Liabilities shall be calculated assuming consummation of
the transactions contemplated hereby and by the P City Agreement (except that
the Venture shall not be treated as consolidated with the Company).  With
respect to each Preliminary Net Quick Asset Schedule and each Closing Net Quick
Asset Schedule, the amount (positive or negative) equal to Quick Assets less
Quick Liabilities is referred to as "Net Quick Assets."  The Preliminary Net
Quick Asset Schedules and the Closing Net Quick Asset Schedules shall be
prepared in accordance with GAAP applied in a manner consistent with that
utilized in the preparation of the Financial Statements, except as provided
above. To the extent that, during the period January 1, 1998 through the Closing
Date, (i) any sale by the Company, any of its Subsidiaries or the Venture of any
real property, or any item of personal property with a sale price exceeding
$25,000, occurs or has occurred or (ii) any proceeds are or have been received
by the Company, any of its Subsidiaries or the Venture as a result of any
condemnation, casualty or any similar event, the proceeds from any such sale or
other event shall, regardless of the form in which received, be deducted in the
determination of Net Quick Assets and not be deemed to be Quick Assets and any
corresponding liability shall not be deemed to constitute Quick Liabilities for
the purposes of such determination.   In addition, the matters identified in
Schedule III to this Agreement shall not be deemed to consitute Quick
Liabilities for the purpose of such determination.

          (ii) If, as set forth on the Preliminary Net Quick Assets Schedules,
the combined Quick Liabilities exceed the combined Quick Assets by an amount in
excess of $1,000,000, the Post-Closing Escrow Amount shall be increased by the
amount of such shortfall.
                          
          (iii)    If, based on the Closing Net Quick Assets Schedules, the
combined Net Quick Assets exceed zero, the Buyer will, no later than the later
of (A) thirty (30) days following the delivery of the Closing Net Quick Assets
Schedules or (B) 5 Business Days

                                      -20-
<PAGE>
 
following the resolution of a dispute with respect to any items on the Closing
Net Quick Assets Schedules as set forth in subsection (iv) hereof (the
"Settlement Date"), pay to the Representative, on behalf of the Company
Stockholders and PCI, the amount of such excess, together with interest thereon
calculated as described below, by wire transfer of immediately available funds
to an account designated by the Representative, subject to (S)2(j) hereof. If
the combined Closing Net Quick Assets are less than zero, the Representative
will cause the Post-Closing Escrow Agent to pay to the Buyer, no later than the
Settlement Date, the amount of such shortfall, together with interest thereon
calculated as described below, by wire transfer of immediately available funds
to an account designated by the Buyer. The amount, if any, payable pursuant to
this clause (iii), together with interest thereon at the rate of interest paid
from time to time on the Post-Closing Escrow Fund from the Closing Date up to
and including the date of payment is hereafter referred to as the "Adjustment."

          (iv) If the Representative in good faith disagrees with any items on
the Closing Net Quick Assets Schedules, the Representative shall notify the
Buyer and the Post-Closing Escrow Agent in writing of such disagreement within
twenty-nine (29) days after the Representative's receipt of the Closing Net
Quick Assets Schedules. Such notice shall set forth the basis for such
disagreement in reasonable detail. During such twenty-nine (29) day period, the
Buyer shall afford the Representative access to all of the Surviving
Corporation's books and records and cause the Buyer's accountants to afford the
Representative access to all of the work papers of the Buyer's accountants
during regular business hours as required by the Representative to review the
Closing Net Quick Assets Schedules, in each case, solely for the purposes of
resolving such disagreement. The Buyer and the Representative shall thereafter
negotiate in good faith to resolve any such disagreements, provided that the
Representative shall promptly cause the Escrow Agent to pay to the Buyer, or the
Buyer shall promptly pay to the Representative on behalf of the Company
Stockholders and PCI, as the case may be, the portion of the Adjustment that is
not subject to dispute.

          (v)  If the Buyer and the Representative are unable to resolve any
such disagreements within twenty (20) days after the expiration of the twenty-
nine-day period referred to in clause (iv), the Buyer and the Representative
shall use their reasonable best efforts to cause the Chicago office of Arthur
Andersen LLP, acting as an independent arbitrator, (the "Auditor") to resolve
all disagreements on the disputed items as soon as practicable, provided that
the Auditor shall be bound by the provisions of this (S) 2(k) and may not assign
a value to any item greater than the greatest value for such item claimed by
either the Buyer or the Representative or less than the smallest value for such
item claimed by either the Buyer or the Representative. Each of the Buyer and
the Representative shall permit the Auditor to have full access to its books,
records, key employees and independent accountants, in each case solely in order
to resolve any such disagreements. The resolution of such disagreements by the
Auditor shall be final and binding on the Buyer, the Company Stockholders, PCI
and the Representative. The fees and expenses of the Auditor shall be paid by
the party whose position is most at variance with the decision of the Auditor,
as determined by the Auditor which, if required to be paid by the Representative
on behalf of the Company Stockholders and PCI, shall be paid out of the Escrow
Fund in accordance with the terms of the Post-Closing Escrow Agreement. Any

                                     -21-
<PAGE>
 
payment by the Buyer to the Representative shall be net of amounts to be
withheld pursuant to (S) 2(j).

     (l)  Further Assurances. Each Party hereto and the Representative, in its
capacity as representative of PCI and the Schedule I Stockholders, will, either
prior to or after the Effective Time, execute such further documents,
instruments, deeds, bills of sale, assignments and assurances and take such
further actions as may reasonably be requested by one or more of the others to
consummate the transactions contemplated hereby, to vest the Surviving
Corporation with full title to all assets, properties, privileges, rights,
approvals, immunities and franchises of the Company and to effect the other
purposes of this Agreement.

     (m)  Chargeable Violations. Notwithstanding that Chargeable Violations are
Permitted Exceptions, if on the Closing Date Chargeable Violations exist which
have not been cured, then the Buyer shall be entitled as its sole and exclusive
remedy to a credit against the Merger Consideration in an amount equal to the
cost of curing said Chargeable Violations, as reasonably determined by Buyer and
the Company, it being understood and agreed that no credits either individually
or in the aggregate under this (S) 2(m) shall exceed $3,000,000. In furtherance
of the foregoing, and notwithstanding anything in this Agreement to the
contrary, the Buyer acknowledges and agrees that it shall have no right to
terminate this Agreement by reason of the existence of any violations of laws,
ordinances, orders, requirements, or regulations of any governmental authority
relating to the Shopping Centers, including Chargeable Violations and Seller
shall have no obligation to cure or remove any violations of laws, ordinances,
orders, requirements or regulations of any governmental authority including
Chargeable Violations.

warrants to the Buyer and the Transitory Subsidiary that the statements

those jurisdictions set forth in the Disclosure Schedule, which are the only

such qualification, individually or in the aggregate and together with any other

Effect. Each of the Company and its Subsidiaries has full corporate power and
authority to carry on the business in which it is engaged and to own or lease
the properties owned or leased by it. The Company has delivered to the Buyer
complete and correct copies of its Restated Certificate of Incorporation and By-

Immediately prior to the Effective Time, the Company will own a 50% interest in
the Venture directly (or indirectly through Company Sub) and the remaining 50%
interest in the Venture indirectly through Parcity Inc., in each case, free and

interests. There are no outstanding or authorized options, warrants, puts,

rights or exchange rights or other contracts or commitments that could require
any Subsidiary or the Venture to issue, sell or otherwise cause to become
outstanding any equity or other interests, except as contemplated by this

Company, PCI and Park City, except that the Company cannot consummate the Merger
unless and until it receives the Requisite Stockholder Approval and the
transactions contemplated by the P City Agreement must be approved by the
stockholders of Park City. This Agreement has been duly executed and delivered
by the Company and, assuming the due authorization, execution and delivery
hereof by the other Parties and subject to the receipt of the Requisite
Stockholder Approval, which is the only vote required in respect of the Company
(including its stockholders) in order to approve the Merger and the other
transactions contemplated hereby, constitutes the valid and legally binding
obligation of the Company, enforceable in accordance with its terms. The P City
Agreement and the Deposit Escrow Agreement have been, and the other agreements
contemplated hereby will, prior to the Closing be, duly executed and delivered
by the Company, PCI and/or Park City, as the case may be, and constitute, or
will constitute, as the case may be, the valid and legally binding obligations

the imposition of any Lien upon any of its assets), except where, in the cases
of clauses (i) and (iii), any such violations, conflicts, breaches, defaults,
accelerations, terminations, modifications, cancellations, failures to give
notice or Liens would not, individually or in the aggregate, have a Material
Adverse Effect. Other than as required by the Delaware General Corporation Law,
none of the Company and its Subsidiaries, PCI or the Venture needs to give any
notice to, make any filing with or obtain any authorization, consent or approval
of any government or governmental agency or other Person in order for the
Parties to execute and deliver this Agreement, the P City Agreement and the
other agreements contemplated hereby or consummate the transactions contemplated

performance of this Agreement, the P City Agreement and the other agreements
contemplated hereby and the consummation of the transactions contemplated hereby
and thereby will not permit any stockholder, partner, joint venturer or other
holder of an interest in the Company, any Subsidiary, PCI or the Venture to
exercise or invoke any buy-sell, right of first refusal or first offer, purchase
option or other purchase or option right.

     member of a consolidated, combined or unitary group for federal, state,
     local or foreign tax purposes.

Stockholders, that the statements contained in this (S) 4 are correct and
complete as of the date of this Agreement.

     (a)  Organization.  The Buyer is a limited partnership, and the Transitory
Subsidiary is a limited liability company, in each case, duly organized, validly
existing and in good standing under the laws of the State of Delaware.  Each of

by the Buyer and the Transitory Subsidiary, respectively. This Agreement has
been duly executed and delivered by the Buyer and the Transitory Subsidiary
under applicable Delaware law and in accordance with its partnership agreement
or operating agreement, as the case may be, and, assuming the due authorization,
execution and delivery hereof by the other Parties, constitutes the valid and
legally binding obligation of each of the Buyer and the Transitory Subsidiary,

Transitory Subsidiary will be parties, will prior to the Closing be duly
executed and delivered by the Buyer and/or the Transitory Subsidiary, as the

transactions contemplated hereby and thereby will (i) violate any statute,
regulation, rule, injunction, judgment, order or decree of any government,
governmental agency or court to which the Buyer or the Transitory Subsidiary is
subject or by which it or its assets may be bound or any provision of the

or by which it is bound or to which any of its assets is subject (or result in
the imposition of any Lien upon any of its assets), except where the violation,
conflict, breach, default, acceleration, termination, modification,
cancellation, failure to give notice or Lien would not have a material adverse
effect on the ability of the Buyer or the Transitory Subsidiary to consummate
the transactions contemplated by or perform its obligations under this
Agreement.  Except for the filing of the Certificate of Merger in Delaware,
neither the Buyer nor the Transitory Subsidiary needs to give any notice to,
make any filing with or obtain any authorization, consent or approval of any
government or governmental agency  or other Person in order for such Parties to
execute and deliver this Agreement and the other agreements contemplated hereby
to which they are parties or to consummate the transactions contemplated hereby
and thereby.

     (e)  Litigation.  There is no suit, action or proceeding pending or, to the
knowledge of the Buyer or the Transitory Subsidiary, threatened against or
affecting the Buyer or the Transitory Subsidiary that, individually or in the
aggregate, could reasonably be expected to have a material adverse effect on the
ability of the Buyer or the Transitory Subsidiary to consummate the transactions
contemplated by or perform its obligations under this Agreement, nor is there

warranties of the Company or the Buyer and the Transitory Subsidiary set forth

Agreement, which shall survive the Closing until the first anniversary of the

which expires at the Closing shall, notwithstanding anything to the contrary
herein, not be deemed to limit in any respect any representation, warranty or
other provision of this Agreement or the agreements contemplated hereby which

agree that none of the Buyer, the Transitory Subsidiary or the Surviving
Corporation is permitted to assert against any Schedule I Stockholder or PCI or

     Company, its Subsidiaries or PCI will merge or consolidate with or into any
     Person;

          (v)    none of the Company, its Subsidiaries or the Venture will issue
     any note, bond or other debt security, create, incur, assume or guarantee
     any indebtedness for borrowed money or capitalized lease obligations or

     each case which will continue to be outstanding or otherwise remain in

                                      -40-

          (vi)    none of the Company, its Subsidiaries or the Venture will
     impose any Lien or permit to exist any new Lien upon any of its assets
     outside the Ordinary Course of Business (other than new Liens which do not

     assets of any other Person outside the Ordinary Course of Business except
     as contemplated by the current capital expenditure budgets of the Company

     of Directors of the Company or the Venturers, as the case may be, and
     provided to the Buyer;

          (viii)  none of the Company, its Subsidiaries or the Venture will

     not in the Ordinary Course of Business and;

          (x)     none of the Company, its Subsidiaries or the Venture will
     cancel any indebtedness for borrowed money owed to it, other than in return
     for full payment thereof, whether or not in the Ordinary Course of
     Business;

          (xi)    none of the Company, its Subsidiaries or the Venture will
     engage in any new transaction outside of the Ordinary Course of Business or

Closing Date.  Such Tax Returns and Reports shall be prepared on a basis
consistent with those prepared for prior tax years unless a different treatment
of any item is required by an intervening change in law.  Notwithstanding the
foregoing, with respect to each year in which Parcity Inc. or PCI owned an

Returns with the Pennsylvania Department of Revenue and to pay the corporate

waived in writing by the Pennsylvania Department of Revenue.  In addition, prior
to Closing, the Company shall cause the Venture to file a Pennsylvania

Subsidiaries and the Venture to) permit representatives and agents of the Buyer
to have full access at all reasonable times, and in a manner so as not to
interfere with the normal business operations of the Company, its Subsidiaries
or the Venture, to all premises, properties, personnel, officers, accountants,
agents, books, records (including tax records), contracts and documents of or
pertaining to the Company, its Subsidiaries and the Venture and to make
photocopies of any such books, records, contracts and documents at no cost to
the Company or the Schedule I Stockholders and PCI. The Buyer will treat and

Subsidiaries or the Venture in the course of the reviews contemplated by this
(S) 7(e), in accordance with the terms of the Confidentiality Agreement. The

to amend or supplement the Disclosure Schedule or to qualify any representation,
warranty, covenant, indemnity or other agreement contained herein or in the
agreements contemplated hereby or any condition to the obligations of the
Parties hereto.  In addition, it is acknowledged and agreed that:

                                      -42-
<PAGE>
 
          (i)   The Company shall deliver or cause to be delivered to the Buyer,
     promptly upon receipt thereof by the Company, any of its Subsidiaries, PCI
     or the Venture, copies of any notices received or given by the Company, any
     of its Subsidiaries, PCI or the Venture from or to any Person alleging or
     relating to any violation of applicable law or any default, or the
     occurrence of any event which could result in a default, under any of the
     Leases, the REAs or the Service Contracts.

          (ii)  The Company shall advise the Buyer promptly in writing of the
     receipt, by the Company, any of its Subsidiaries, PCI or the Venture, of
     notice of the institution of any litigation or judicial, quasi-judicial or
     administrative inquiry or proceeding with respect to any of the Shopping
     Centers or the Company, any of its Subsidiaries, PCI or the Venture,
     including any legal proceedings or condemnation proceedings, any notice of
     a violation issued by any governmental authority with respect to any of the
     Shopping Centers, any actual or proposed special assessment or change in
     the assessed value of any of the Shopping Centers or any portion thereof,
     any notice from any insurance company or fire rating bureau of any material
     defects or inadequacies in any of the Shopping Centers or any part thereof
     or any notice of the unavailability of any licenses or permits hereafter
     required in connection with the ownership or operation of any of the
     Shopping Centers. Without the written consent of the Buyer, which shall be
     given or withheld by the Buyer acting in accordance with its business
     judgment, exercised in good faith after giving due consideration to the
     Company's recommendations, neither the Company, any of its Subsidiaries,
     PCI nor the Venture will withdraw, settle or otherwise compromise any
     protest or reduction proceeding affecting real estate taxes or the charges
     assessed against any of the Shopping Centers.

     (g)  Indemnification; Directors' and Officers' Insurance

          (i)  For a period of six (6) years from and after the Effective Time,
     the Buyer and the Surviving Corporation (collectively, the "Indemnifying
     Parties") shall indemnify, defend and hold harmless each person who is now
     or has been at any time prior to the date hereof, or who becomes prior to
     the Effective Time, an officer or  director of the Company, any of its
     Subsidiaries or the Venture or a trustee of the Trust (the "Indemnified
     Parties") against all losses, claims, damages, liabilities, judgments,
     amounts that are paid or to be paid in settlement with the approval of the
     Indemnifying Party (which approval shall not be unreasonably withheld or
     delayed), costs or expenses (including reasonable attorneys' fees and
     expenses), or assessments that are incurred or otherwise suffered by any
     Indemnified Party in connection with any threatened or actual claim,
     action, suit, proceeding or investigation based on or arising out of the
     fact that such Person is or was an officer or director of the Company or
     any of its Subsidiaries at or prior to the Effective Time, whether asserted
     or claimed prior to, or at or after, the Effective Time, which arises out
     of any action occurring at or prior to the Effective Time ("Indemnified
     Liabilities"), including all Indemnified Liabilities based on, or arising
     out of, or pertaining to this Agreement or the transactions contemplated by
     this Agreement, in each case to the full extent a corporation is permitted
     under the Delaware General

                                      -43-
<PAGE>
 
     Corporation Law to indemnify its own directors or officers.  The
     Indemnifying Party shall pay expenses in advance of the final disposition
     of any such action or proceeding to each Indemnified Party to the full
     extent permitted by law, provided that the Person to whom expenses are
     advanced provides an undertaking to repay such advance if it is ultimately
     determined that such Person is not entitled to indemnification.  Any
     Indemnified Parties proposing to assert the right to be indemnified under
     this (S) 7(g) shall, promptly after receipt of notice of commencement of
     any action against such Indemnified Parties in respect of which a claim is
     to be made under this (S) 7(g) against the Buyer or the Surviving
     Corporation, notify the Indemnifying Parties of the commencement of such
     action, enclosing a copy of all papers served.  The failure to so notify
     the applicable Indemnifying Party shall not relieve such Indemnifying Party
     from any liability which it may have under this Section, except to the
     extent such failure prejudices such Indemnifying Party.  If any such action
     is brought against any of the Indemnified Parties and such Indemnified
     Parties notify the Indemnifying Parties of its commencement, the
     Indemnifying Parties will be entitled to participate in and, to the extent
     that they elect, by delivering written notice to such Indemnified Parties
     promptly after receiving notice of the commencement of the action from the
     Indemnified Parties, to assume the defense of the action, and, after notice
     from the Indemnifying Parties to the Indemnified Parties of their election
     to assume the defense, the Indemnifying Parties will not be liable to the
     Indemnified Parties for any legal expenses with respect to such action
     except as provided below.  If the Indemnifying Parties assume the defense,
     the Indemnifying Parties shall have the right to settle such action without
     the consent of the Indemnified Parties; provided, however, that the
     Indemnifying Parties shall be required to obtain such consent (which
     consent shall not be unreasonably withheld or delayed) if the settlement
     includes any admission of wrongdoing on the part of the Indemnified Parties
     or any decree or restriction on the Indemnified Parties; provided, further,
     that no Indemnifying Parties in the defense of any such action shall,
     except with the consent of the Indemnified Parties (which consent shall not
     be unreasonably withheld), consent to entry of any judgment or enter into
     any settlement that does not include as an unconditional term thereof the
     giving by the claimant or plaintiff to such Indemnified Parties of a
     release from all liability with respect to such action. The Indemnified
     Parties will have the right to employ their own counsel in any such action,
     and the fees, expenses and other charges of such counsel will be at the
     expense of the Indemnified Parties unless (i) the employment of counsel by
     the Indemnified Parties has been authorized in writing by the Indemnifying
     Parties, (ii) the Indemnified Parties have reasonably concluded (based on
     advice of counsel) that there may be legal defenses available to them that
     are different from or in addition to those available to the Indemnifying
     Parties, (iii) a conflict or potential conflict exists (based on advice of
     counsel to the Indemnified Parties) between the Indemnified Parties and the
     Indemnifying Parties (in which case the Indemnifying Parties will not have
     the right to direct the defense of such action on behalf of the Indemnified
     Parties) or (iv) the Indemnifying Parties have not in fact employed counsel
     to assume the defense of such action within a reasonable time after
     receiving notice of the commencement of the action, in each of which cases
     the reasonable fees, disbursements and other charges of counsel will be at
     the expense of the Indemnifying Parties. It is understood that the
     Indemnifying

                                      -44-
<PAGE>
 
     Parties shall not, in connection with any proceeding or related proceedings
     in the same jurisdiction, be liable for the reasonable fees, disbursements
     and other charges of more than one separate firm admitted to practice in
     such jurisdiction at any one time from all such Indemnified Parties unless
     (a) the employment of more than one counsel has been authorized in writing
     by the Indemnifying Parties or (b) there is, under applicable standards of
     professional conduct (based on advice of counsel), a conflict on any
     significant issue between the positions of any two or more Indemnified
     Parties, in each of which cases the Indemnifying Parties shall be obligated
     to pay the reasonable and appropriate fees and expenses of one additional
     counsel.  The Indemnifying Parties will not be liable for any settlement of
     any action or claim effected without their written consent (which consent
     shall not be unreasonably withheld or delayed).

          (ii)   The provisions of this (S) 7(g) are intended to be for the
     benefit of, and shall be enforceable by, each Indemnified Party, his or her
     heirs and his or her personal representatives and shall be binding on all
     successors and assigns of the Buyer and the Surviving Corporation.

          (iii)  The Buyer shall either (A) cause the Surviving Corporation to
     extend the Company's existing directors and officers liability insurance
     policy as of the date hereof (or a policy providing coverage on comparable
     terms and conditions) for acts or omissions occurring prior to the
     Effective Time by Persons who are covered as of the date of this Agreement
     by such insurance policy maintained by the Company for a period of six (6)
     years following the Effective Time, or (B) add such Persons to the existing
     directors and officers liability insurance policy of the Buyer or an
     Affiliate; provided, however, that, for purposes of this clause (B), such
     insurance shall provide officers and directors of the Company the same
     coverage as similarly situated officers and directors of the Buyer and such
     insurance shall be maintained by the Buyer for a period of six years
     following the Effective Time. Notwithstanding the preceding sentence, in no
     event shall the Buyer or the Surviving Corporation be required to expend on
     average over such six year period in excess of 125% of the annual premium
     currently paid by the Company for such coverage and, if the premium for
     such coverage on average over such six year period exceeds such amount, the
     Buyer or the Surviving Company shall purchase a policy with the greatest
     coverage available for such 125% of the annual premium.

          (iv)   In the event that the Buyer or any of its successors or assigns
     consolidates with or merges into any other Person and shall not be the
     continuing or surviving corporation or entity of such consolidation or
     merger or transfers all or substantially all of its properties and assets
     to any Person, then, and in each such case, the successors and assigns of
     such entity shall, as a condition precedent to such consolidation, merger
     or transfer, assume the obligations set forth in this (S) 7(g), which
     obligations are expressly intended to be for the irreversible benefit of,
     and shall be enforceable by, each officer and director covered hereby.

     (h)  Contracts, Transfers and Encumbrances.  The Company will not (and will
cause each of its Subsidiaries and the Venture not to), without the prior
written consent of the Buyer, which consent shall be given or withheld by the
Buyer acting in accordance with its business judgment, exercised in good faith
after giving due consideration to the Company's recommendations:

          (i)    extend, renew, terminate, replace, amend, supplement or modify
     any Service Contract (other than as may be required pursuant to its
     existing terms), or enter into any new Service Contract with respect to any
     of the Shopping Centers which will survive the Closing or otherwise affect
     the use, operation or enjoyment of the Shopping Centers after the Closing
     or increase the obligations of the Company, any Subsidiary or the Venture
     thereunder;

          (ii)   waive any material rights of the Company, any of its
     Subsidiaries or the Venture under any Service Contracts;

          (iii)  sell, transfer, convey or encumber, or cause or permit to be
     sold, transferred, conveyed or encumbered, any of the Shopping Centers, or
     any part thereof or interest therein, or agree to or support any adoption
     of, amendment to or revocation of any environmental, zoning, subdivision,
     land use, building or similar law affecting the Shopping Centers or enter
     into any easements or restrictive covenants which burden any of the
     Shopping Centers; or

          (iv)   perform or permit any act which shall diminish, encumber or
     adversely affect the Company's, any of its Subsidiaries' or the Venture's
     rights in and to the Shopping Centers or prevent the Company from
     performing its obligations hereunder.

     (i)  Tenant Leases and REAs.  The Company, each of its Subsidiaries and the
Venture shall fully and faithfully perform all of the landlord's covenants,
agreements and obligations under the Leases and the REAs to which it is a party,
consistent with past practice.  Neither the Company or any of its Subsidiaries
nor the Venture will, without the prior written consent of the Buyer, which
consent shall be given or withheld by the Buyer acting in accordance with its
business judgment, exercised in good faith after giving due consideration to the
Company's recommendations:

          (i)   Enter, or commit to enter, into any new reciprocal easement
     agreement or lease or sublease for space in any of the Shopping Centers
     which is in excess of 1,000 square feet.

          (ii)  Agree to any alteration, amendment, supplement, extension,
     termination, cancellation or revision of any REA or Lease involving any
     space in any of the Shopping Centers which is in excess of 1,000 square
     feet and for a term of more than 90 days heretofore entered into or which
     may hereafter be entered into as provided in this (S) 7(i).

                                      -46-
<PAGE>
 
          (iii)  Accept any rent more than one month in advance or any security
     deposit not reflected in a Lease.

          (iv)   Release any of the material obligations of the tenants under
     the Leases or the REA Parties under the REAs.

          (v)    Consent to any assignment or sublease of any Lease except to
     the extent required by the terms of the Lease.

     (j)  Notice.  In connection with any action set forth in (S) 7(h) or (i)
above that requires the Buyer's consent, the Company shall deliver to the Buyer
a written notice of each proposed action hereunder stating, if applicable,
whether the Company is willing to consent to such action and setting forth the
relevant information relating thereto and, if applicable, the number of days
within which the Company must respond to the proposed action under the terms of
the applicable Lease, REA or Service Contract, together with any other material
information supplied to the Company as to the proposed action.  The Buyer shall,
except as provided in the last sentence of this (S) 7(j), have ten (10) days
after delivery to it of such notice and information to determine whether or not
to approve such action.  If the Buyer shall not give notice of its disapproval
within such ten (10) day period, the Buyer shall be deemed to have approved such
action and the Company may proceed to take such action in its discretion.  If
any Lease, REA or Service Contract provides the Company, by its express terms,
with fewer than ten (10) days within which to grant any such approval or
disapproval, such ten (10) day period provided for above shall be reduced to one
(1) Business Day less than the number of days provided for in such Lease, REA or
Service Contract and the written notice to the Buyer shall specifically state
the time period for the Buyer's approval.

     (k)  Estoppel Letters; Rent Roll.  (i) The Company agrees to request
estoppel certificates from all tenants, REA parties, the ground lessor at
Northgate Mall and from Connecticut General Life Insurance Company as lender at
Meadows Mall.

     (ii)  On or before the date that is five (5) Business Days prior to the
Closing Date, the Company shall furnish to the Buyer, an estoppel certificate
completed by each anchor tenant (as identified on Exhibit L-1 hereto) who is
required to deliver an estoppel certificate pursuant to its Lease, each REA
Party who is required to deliver an estoppel certificate pursuant to its REA,
not less than seventy five percent (75%) of the tenants, other than the anchors,
who are required to deliver an estoppel certificate pursuant to their Lease, the
ground lessor at the Northgate Mall and Connecticut General, as lender with
respect to Meadows Mall.  The estoppels shall be either (x) on the form
specified in the Lease, REA, or mortgage, as the case may be, or (y) on the form
attached hereto and incorporated herein as Exhibit L-2 for tenants (a "Tenant
Estoppel"), or the form attached hereto and incorporated herein as Exhibit L-3
for each REA Party (an "REA Estoppel"), or  the form attached hereto and
incorporated herein as Exhibit L-4 for the ground lessor (the foregoing are
hereinafter collectively referred to as the "Estoppels").  The Company shall use
its reasonable best efforts to obtain and deliver the Estoppels specified in
this clause (ii) it being understood and agreed, however, that if an estoppel
certificate is received

                                      -47-
<PAGE>
 
which is in a form different from the form specified in the Lease, REA or
mortgage, as the case may be, or different from the form specified herein, said
estoppel certificate shall nevertheless be deemed duly received for purposes of
this Agreement and the Company's obligations hereunder provided the Estoppel
does not contain information which is materially different from that previously
disclosed in writing to the Buyer.

     (iii)  Prior to the Closing an updated version of the Rent Roll shall be
delivered by the Company to the Buyer which shall be dated as of a date no more
than five (5) Business Days prior to the Closing.

     (l)  Taxes; Notices; Lease Negotiations; and Insurance.  The Company shall,
at all times:

          (i)    pay or cause to be paid when due all real estate taxes, special
     assessments, sales taxes and other Taxes, brokerage commissions and other
     charges required to be paid by the Company, any of its Subsidiaries or the
     Venture, except for any real estate taxes, special assessments, sales taxes
     or other Taxes, brokerage commissions or other charges that are being
     contested in good faith, and for which appropriate accruals on the
     Company's financial statements and general ledgers have been established
     and which are disclosed in writing to the Buyer;

          (ii)   advise the Buyer from time to time, at the request of the
     Buyer, of the status of any negotiations with prospective tenants of the
     Shopping Centers or with other parties with whom contracts or agreements
     are being negotiated; and

          (iii)  file all returns and reports required by any governmental
     authority with respect to the Shopping Centers or the ownership, use or
     occupancy thereof and provide copies thereof to the Buyer.

     (m)  Other Obligations.  The Company shall, and shall cause its
Subsidiaries, PCI and the Venture to, perform all obligations required by the
terms of this Agreement, the P City Agreement and the other agreements
contemplated hereby to be performed by them, shall perform or cause to be
performed when due all of the Company's, its Subsidiaries' and the Venture's
obligations under, and shall comply and cause its Subsidiaries and the Venture
to comply with all applicable provisions of, the Service Contracts, the
insurance policies, governmental approvals and all Licenses and Permits and
other agreements, encumbrances and restrictions relating to the Shopping Centers
and shall comply with all applicable laws, including, without limitation, the
requirements of any governmental authority with respect to any tax abatement or
exemption benefitting the Shopping Centers.  The Company shall not cause or
permit any Hazardous Materials to be stored, released or disposed of on, under
or at the Shopping Centers or any part thereof and shall promptly notify the
Buyer in writing if any Hazardous Materials are discovered at the Shopping
Centers.

                                      -48-
<PAGE>
 
     (n)  Contest.  If any proceedings are filed seeking to enjoin or otherwise
prevent or declare unlawful the occupancy, maintenance or operation of any of
the Shopping Centers or any portion thereof, the Company shall (i) notify the
Buyer of such proceedings, (ii) cause such proceedings to be vigorously
contested in good faith and (iii) in the event of an adverse ruling or decision,
prosecute all allowable appeals therefrom.

     (o)  Transfer Taxes.  The Buyer and the Company shall cooperate in the
preparation, execution and filing of all returns, reports or other documents
regarding any real property transfer or gains, sales, use, transfer, value
added, stock transfer and stamp Taxes, any  transfer, recording, registration
and other fees,  and any similar Taxes which become payable in connection with
the transactions contemplated by this Agreement and the P City Agreement
("Transfer Taxes") and the Schedule I Stockholders and PCI shall be responsible
for the payment thereof, other than any Pennsylvania Commonwealth Transfer Tax,
which shall be the responsibility of the Buyer.  In particular, the Company
shall use its reasonable best efforts to obtain prior to Closing a final
settlement regarding any applicable Pennsylvania local real estate Transfer
Taxes on the transactions contemplated by this Agreement and the P City
Agreement.  Such settlement shall document the names of the relevant Affiliates
and shall be binding on the City of Lancaster, the School District of Lancaster,
and any other subdivision of the Commonwealth of Pennsylvania in which the Park
City Center is located.  The Company shall keep the Buyer informed of its
discussions and written filings with the local taxing authorities and shall
reasonably consult in good faith with the Buyer before making or accepting any
settlement offer or submitting any written filings.  The Closing Expense Fund
shall reflect the amount of any local real estate Transfer Tax which is agreed
to be due with the local taxing authorities or, in the absence of such an
agreement, such amount as the Company shall in good faith estimate to be due
upon a determination or settlement plus actual and estimated legal and
accounting fees and expenses relating thereto; provided that the Buyer
Indemnified Parties (as defined in the Post-Closing Escrow Agreement) shall be
indemnified pursuant to Section 4.1(c) of the Post-Closing Escrow Agreement in
respect of any amount which becomes due in excess of such estimates.

     (p)  Exclusivity.  The Company shall notify the Buyer promptly if any
proposal or offer, or any inquiry or other contact with any Person with respect
to the acquisition of any of the capital stock (or other interests) or any
material assets of any of the Company, any Subsidiary, PCI or the Venture
(including any acquisition structured as a merger, consolidation or share
exchange), is made and shall, in any such notice to the Buyer, indicate in
reasonable detail the identity of the Person making such proposal, offer,
inquiry or contact and the terms and conditions of such proposal, offer, inquiry
or other contact.  The Company shall immediately cease and cause to be
terminated all existing discussions, conversations, negotiations and other
communications with any Persons other than with the Buyer and its Affiliates and
representatives with respect to the foregoing.  The Company will not (and will
not cause or permit any of its Subsidiaries or the Venture or any of their
officers, directors, employees, financial advisors or other representatives) to
provide Confidential Information to any third party (other than representatives
of Buyer and its Affiliates).  The Company agrees not to, and to cause each
Subsidiary, PCI and the Venture not to, without the prior written consent of the

                                      -49-
<PAGE>
 
Buyer, release any Person from, or waive any provision of, any confidentiality
or standstill agreement to which the Company, any Subsidiary or the Venture is a
party.

     (q)  Governmental Entities.  Without the prior written consent of the
Company, such consent not to be unreasonably withheld or delayed, prior to the
Closing, the Buyer shall not contact any governmental entity having jurisdiction
over the Shopping Centers or any part thereof with respect to any matter
relating to the condition or operation of the Shopping Centers; provided, that,
in the event the Company so consents to such contact, the Buyer shall indemnify
and hold harmless the Company, its Subsidiaries, PCI and the Venture from any
costs, losses and claims arising from any note or notice of violation from such
governmental authority related to such contact.  The foregoing indemnity shall
not cover any such contact made by the Title Company that is not directed by the
Buyer.

     (r)  Employees.  (i) As of the Closing Date, the Representative shall
terminate or cause the termination of the employment of all of its and its
Affiliates' employees who are employed in the conduct of the business of the
Company, its Subsidiaries and the Venture, except for the employees of the
General Maintenance Group at the Mayfair Shopping Center (the "Represented
Employees"), and any and all obligations of the Representative with respect to
such terminated employees shall end as of the date on which the employment of
such employees is terminated by the Representative or its Affiliates.  The Buyer
may offer employment thereafter to such terminated employees as it shall
determine in its sole discretion and shall be solely responsible for any and all
obligations arising out its employment of any such terminated employees.

     (ii) As of the Closing Date, the Buyer or an Affiliate thereof shall (a)
assume the obligations of Mayfair and ERE Yarmouth under the Agreement between
Mayfair and the Local 150, Service Employees International Union AFL-CIO, CLC
(the "CBA"), (b) adopt the Froedtert-Mayfair, Inc. Retirement Income Plan for
Employees Represented by Local #125 for the benefit of the Represented Employees
and (c) continue the employment of the Represented Employees pursuant to the
CBA.

     8.   Delivery of Title Commitments and Surveys.

     (a)  Prior to the date hereof, the Company has caused the Title Company to
deliver the Title Commitments and the Surveyors to deliver the Surveys to the
Buyer.  The cost of the title examinations related to the Title Commitments and
the Surveys and the premiums for basic coverage in respect of the Title Policies
shall be borne by the Schedule I Stockholders.  The cost of coverage in excess
of basic coverage under the Title Policies shall be borne by the Buyer.

     (b)  If any update of the Title Commitments or the Surveys delivered to the
Buyer after the date hereof disclose any matters other than the Permitted
Exceptions, the Buyer shall notify the Company in writing (a "Disapproval
Notice") within fifteen (15) days after the Buyer's receipt of such update. The
Disapproval Notice shall specify the title objections.  The Buyer's failure to
give such notice shall be deemed an election by the Buyer to waive such title

                                      -50-
<PAGE>
 
objections without compensation or offset or abatement to or of the Merger
Consideration and without warranty by or recourse against the Company, any of
its Subsidiaries or the Venture of any nature whatsoever with respect thereto,
and the Buyer shall thereupon take and accept title to the Shopping Centers "as
is".

     The Company (A) shall cause all Mandatory Cure Items (as hereinafter
defined) to be removed or, in the case of clause (2)(I)(y) or (z) of the
definition of Mandatory Cure Item, bonded or insured over by the Title Company,
at or prior to the Closing and the Company shall deposit with the Buyer or the
Title Company releases, bonds or other appropriate instruments, in recordable
form (where appropriate), sufficient to cause the removal of such Liens from the
respective Shopping Center or to cause the Title Company to insure over said
Liens or omit them as exceptions to coverage under the Title Policy and (B)
shall notify the Buyer in writing within fifteen (15)Business Days after receipt
of the Disapproval Notice whether the Company will cause all or any of the
matters other than Mandatory Cure Items to be removed, bonded insured over or
cured at or prior to Closing. The term "Mandatory Cure Items" shall mean (1)
mortgages or deeds of trust granted by the Company, any of its Subsidiaries or
the Venture, or (2) monetary liens that (I) are (x) affirmatively placed on the
Shopping Centers by the Company, any of its Subsidiaries or the Venture, (y)
judgment liens against the Company, any of its Subsidiaries or the Venture that
would require the expenditure by the Company any of its Subsidiaries or the
Venture of an aggregate amount of not more than $1,000,000 for each Shopping
Center to remove such judgment liens from title, or (z) mechanics' liens that
result from labor or materials contracted for or required to be paid (whether by
allowances, credit reimbursement, payment or otherwise) by the Company, any of
its Subsidiaries or the Venture, (II) are of a fixed and ascertainable amount
and (III) may be removed solely by the payment of money (other than any such
matters that are the responsibility of any tenant under a Lease, any REA Party
under an REA or any other Person other than the Company, any of its Subsidiaries
or the Venture). The Company shall be deemed to have elected to remove, bond or
cure any matters other than Mandatory Cure Items if the Company does not
affirmatively notify the Buyer to the contrary as aforesaid. If the Company
elects not to remove, bond or cure all such matters which are not Mandatory Cure
Items, the Buyer may elect, in its sole discretion, (m) subject to satisfaction
of the other conditions to Closing, to close the transactions contemplated by
this Agreement without adjustment of the Merger Consideration and take title
subject to any such matters which are not Mandatory Cure Items that the Company
elects not to remove, bond or cure, or (n) to terminate this Agreement. The
Company shall have until the Closing or such later date as may be needed to
remove, bond or cure any matter that it has elected or is required to remove,
bond or cure. The Closing Date may be extended by the Company as necessary to
permit the Company to fulfill its obligations pursuant to this (S) 8(b) but not
beyond ninety (90) days. With respect to title objections which are not
Mandatory Cure Items, the Company agrees to cooperate in good faith with the
Buyer in order to cure said title objections. Except with respect to Mandatory
Cure Items, nothing contained in this Agreement shall require the Company to
bring or defend any action or proceeding, or to incur any expense, or to make
any payment or to do any acts or things of any nature whatsoever in order to
cure any alleged title objection, regardless of the manner in which the same
arose. Notwithstanding anything in this Agreement to the contrary, any action by
the Company resulting in the issuance of

                                      -51-
<PAGE>
 
affirmative coverage or the omission of any alleged title objection from the
Title Policy, whether or not the same are removed of record, shall be deemed a
"cure" for purposes of this Agreement.

     (c)  If any matter that is not a Mandatory Cure Item that the Company has
elected, or is required, to remove or cure has not been removed or cured on or
prior to Closing (as the same may be extended pursuant to clause (b) above), or
provision for their removal or cure to the Buyer's reasonable satisfaction has
not been made at or prior to Closing, the Buyer may elect (no later than the
Closing Date as the same may be adjourned pursuant to clause (b) above), in its
sole discretion and as its exclusive remedy:  (x) subject to satisfaction of the
other conditions to Closing, to close the transactions contemplated hereby
without adjustment to the Merger Consideration and take title subject to any
matters that have not been cured or removed at or before Closing other than in
respect of Mandatory Cure Items as to which the Buyer shall be allowed a credit
against the Merger Consideration for all costs incurred or reasonably estimated
to cure such Mandatory Cure Item or (y) to terminate this Agreement.

10.  Termination.

     (a)  Termination of Agreement and Remedies. Any of the Parties may
terminate this Agreement (whether before or after stockholder approval) as
provided below:

          (i)  the Parties may terminate this Agreement by mutual written
     consent at any time prior to the Effective Time;

          (ii) the Buyer and the Transitory Subsidiary may terminate this
     Agreement by giving written notice to the Company at any time prior to the
     Effective Time (A) in the event the Company has breached any
     representation, warranty or covenant contained in this Agreement, the P
     City Agreement or the other agreements contemplated hereby in any material
     respect, the Buyer or the Transitory Subsidiary has notified the Company of
     the breach and the breach has continued without cure for a period of 20
     days after the notice of breach, or as otherwise provided herein, (B) if
     the Closing shall not have occurred on or before August 31, 1998 by reason
     of the failure of any condition

                                     -56-
<PAGE>
 
     precedent under (S) 9(a) hereof (unless the failure results primarily from
     the Buyer or the Transitory Subsidiary breaching any representation,
     warranty or covenant contained in this Agreement) or (C) if the P City
     Agreement has terminated;

          (iii) the Company may terminate this Agreement by giving written
     notice to the Buyer and the Transitory Subsidiary at any time prior to the
     Effective Time (A) in the event the Buyer or the Transitory Subsidiary has
     breached any representation, warranty or covenant contained in this
     Agreement in any material respect, the Company has notified the Buyer and
     the Transitory Subsidiary of the breach and the breach has continued
     without cure for a period of 20 days after the notice of breach or (B) if
     the Closing shall not have occurred on or before August 31, 1998, by reason
     of the failure of any condition precedent under (S) 9(b) hereof (unless the
     failure results primarily from the Company breaching any representation,
     warranty, or covenant contained in this Agreement); or

          (iv)  any Party may terminate this Agreement by giving written notice
     to the other Parties at any time after the Special Meeting in the event
     this Agreement and the Merger fail to receive the Requisite Stockholder
     Approval.

     (b)  Effect of Termination. If any Party terminates this Agreement pursuant
to (S) 10(a) above, all rights and obligations of the Parties hereunder shall
terminate without any liability of any Party to any other Party (subject to (S)
2(h) and 10(c) hereof and except for any liability of any Party then in breach
for actual but not consequential damages); provided, however, that the
confidentiality provisions contained in (S) 7(e) above and the provisions of
(S)(S) 3(r), 4(g), 11(a) and this (S) 10(b) shall survive any such termination.

     (c)  Remedies. Notwithstanding anything to the contrary set forth herein,
the Company shall be entitled to retain the Deposit as the Company's liquidated
damages (and not as a penalty) and as the Company's exclusive remedy for the
Buyer's default in the event of termination of this Agreement pursuant to
Section 10(a)(iii)(A), it being agreed by the parties that it would be
impracticable and extremely difficult to ascertain the actual damages suffered
by the Company as a result of the Buyer's failure to complete the transactions
contemplated by this Agreement and that, under the circumstances existing as of
the date hereof, the liquidated damages provided for herein represent a
reasonable estimate of the damages which the Company would incur as a result of
such failure.

11.  Miscellaneous.

     (a)  Press Releases and Public Announcements. No Party shall issue any
press release or make any public announcement relating to the subject matter of
this Agreement nor permit any of its Affiliates, representatives or agents to do
the same without the prior written approval of the other Parties which shall not
be unreasonably withheld; provided, however, that any Party may make any public
disclosure it believes in good faith is required by applicable law or any

                                     -57-
<PAGE>
 
listing agreement concerning its publicly-traded securities (in which case the
disclosing Party will use its reasonable best efforts to advise the other Party
prior to making the disclosure).

     (b)  No Third-Party Beneficiaries. This Agreement shall not confer any
rights or remedies upon any Person other than the Parties and their respective
successors and permitted assigns; provided, however, that (i) the provisions in
(S)(S) 2, 4, 5 and 6 above are intended for the benefit of the Company
Stockholders and PCI and (ii) the provisions in (S) 7(g) above concerning
insurance and indemnification are intended for the benefit of the individuals
specified therein and their respective legal representatives.

     (c)  Entire Agreement. This Agreement (including the documents referred to

the Parties concerning the subject matter hereof and supersede any prior
understandings, agreements, or representations by or among the Parties, written
or oral, to the extent they related in any way to the subject matter hereof.

     (d)  Succession and Assignment. This Agreement shall be binding upon and
inure to the benefit of the Parties named herein and their respective successors
and permitted assigns. No Party may assign either this Agreement or any of its
rights, interests or obligations hereunder without the prior written approval of
the other Parties; provided, however, that the Buyer or the Transitory
Subsidiary may assign its respective rights and obligations to any wholly-owned
direct or indirect subsidiary of the Buyer, but no such assignment shall relieve
the Buyer of its obligations hereunder.

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

     (f)  Headings. The section headings contained in this Agreement are
inserted for convenience only and shall not affect in any way the meaning or
interpretation of this Agreement.

     (k)  Construction. The Parties have participated jointly in the negotiation
and drafting of this Agreement. In the event an ambiguity or question of intent

     2.   Grant of Redemption Rights.  

     (a)  Upon the terms and subject to the conditions contained herein, the

Contributing Partner, to require the Partnership to redeem from time to time
part or all of the Units of Contributing Partner for the Cash Purchase Price
("Redemption Rights").

     (b)  Notwithstanding the provisions of Section 2(a), the General Partner
may, in its sole and absolute discretion, assume the obligation of the
Partnership with respect to and satisfy Contributing Partner's exercise of a
Redemption Right by paying to Contributing Partner, at the General Partner's
election (which may be exercised in the General Partner's sole discretion),
either the Cash Purchase Price or the Share Purchase Price (or a combination

Partner's Units (or a portion thereof) to the General Partner for federal income

Partner's Units and the payment of the Purchase Price with respect thereto, such
Person shall be deemed withdrawn as a Partner in the Partnership to the extent
of the Units redeemed or purchased and shall have no further rights or
obligations under this Agreement with respect to such redeemed or purchased
Units; provided, however, that Contributing Partner's rights under this
Agreement with regard to any other Units will continue in full force and effect.

     (e)  No fractional Shares shall be issued hereunder. In lieu of fractional
Shares, the General Partner shall pay cash based on the Current Per Share Market
Price on the relevant Computation Date.

     3.   Exercise of Redemption Rights.

     3.1  Time for Exercise of Redemption Rights.  Contributing Partner may
exercise its Redemption Rights in whole or in part and at any time and from time
to time on or after the first anniversary of the date hereof but prior to the
Expiration Date; provided, however, that the Redemption Rights may not be
exercised at any one time by Contributing Partner with respect to less than
1,000 Units (or all the Units then owned by Contributing Partner if Contributing
Partner owns less than 1,000 Units) or in the event that such exercise of
Redemption Rights (or the assignment of Units or delivery of either the Cash
Purchase Price or the Share Purchase Price with respect thereto) violates the
terms of the Partnership Agreement or applicable law. Once given, a Notice shall
be irrevocable subject to the payment of the Purchase Price for the Units
specified therein in accordance with the terms hereof.

     3.2  Method of Exercise.  The Redemption Rights shall be exercised by
written notice (the "Notice") to the Partnership in the form of Exhibit A
specifying the number of Units to be redeemed and the name or names (with
address) in which any Shares issuable upon such exercise shall be registered if
different than the Contributing Partner.

     3.3  Closing.  The closing of the redemption or purchase and sale pursuant
to an exercise of the Redemption Rights shall occur within 30 days following the
giving of the Notice. Contributing Partner shall execute such documents as the
General

                                       6
<PAGE>
 
Partner may reasonably require in connection with the closing of such redemption
or purchase and sale.

     3.4  Payment of Cash or Issuance of Shares.  At the closing of the 
redemption or purchase and sale of Units pursuant to an exercise of Redemption 
Rights, the Partnership shall deliver to Contributing Partner the Cash Purchase 
Price by check or, in the event that the General Partner has assumed the 
obligations of the Partnership with respect to such exercise of Redemption 
Rights, the General Partner shall deliver to the Partnership, at the election of
the General Partner, which may be exercised in the General Partner's sole 
discretion, either (a) the Cash Purchase Price by check or (b) certificates 
representing the Shares and any other securities constituting the Share Purchase
Price, together with cash in lieu of the issuance of any fraction of a Share as 
provided in Section 2(e), or a combination thereof. 

     4.   Matters Relating to Shares.

     4.1  Registration.  

     (a)  The General Partner shall (i) prepare, file and use reasonable efforts
to cause to become effective on or before the ninetieth day following the first
anniversary of the date hereof a registration statement, which may be on Form S-
3, under the Securities Act relating to the Shares to be issued upon exercise of
the Redemption Rights assuming full satisfaction of the Redemption Rights by
delivery of Shares and (ii) prepare and file with the SEC such amendments and
supplements to such registration statement and the prospectus used in connection
therewith as may be necessary to keep such registration statement effective and
to comply with the provisions of the Securities Act.

     (b)  The General Partner shall pay all Registration Expenses incurred prior
to the sixth anniversary of the date hereof with respect to filing and keeping
effective the registration statement through such date, and the Unitholders
shall reimburse the General Partner for Registration Expenses (or a pro rata
portion of the Registration Expenses based on the number of Shares issuable to
such Unitholders upon full exercise of the Redemption Rights of such Unitholders
relative to the total number of Shares issuable pursuant to such registration
statement) which are incurred after the sixth anniversary of the date hereof in
respect of maintaining effective (but not the initial filing and causing to
become effective of) such

                                       7
<PAGE>
 
registration statement; provided, however, that Contributing Partner shall not
be required to reimburse any costs (i) of preparing any documents filed with the
SEC that are incorporated by reference in the Registration Statement or (ii)
that become necessary because the General Partner is unable to use Form S-3 (or
any equivalent short form that relies on incorporation by reference) for the
reason that the General Partner has failed to comply on a timely basis with any
requirement of the Acts or Form S-3. The reimbursement of such expenses by the
Unitholders shall be paid upon demand.

     (c)  Notwithstanding anything to the contrary contained herein, the General
Partner shall have no obligation to keep any registration statement filed
pursuant to this Section 4.1 effective after the Expiration Date or if the
status of the General Partner (or its successor) as an Exchange Act Reporting
Company is terminated or all of the Unitholders notify the General Partner in
writing that the General Partner no longer need keep such registration statement
effective.

     4.2  Reservation of Shares.  At all times while the Redemption Rights are
outstanding, the General Partner shall reserve for issuance such number of
Shares as may be necessary to enable the General Partner to issue Shares in full
satisfaction of all Redemption Rights which are from time to time outstanding
(assuming no limitations as to the ownership of such Shares under the
Certificate of Incorporation which relate to compliance with the REIT
Requirements and that the General Partner elected to pay the Share Purchase
Price with respect to all such Redemption Rights).

     4.3  Fully Paid and Non-Assessable.  All Shares which may be issued upon
exercise of the Redemption Rights shall be duly and validly issued and fully
paid and non-assessable.

     5.   Transfer and Other Taxes.  In the event that any state or local
property transfer or other tax is payable as the result of or in connection with
any exercise of the Redemption Rights by Contributing Partner, Contributor
Partner shall pay such tax, and no Shares shall be issued pursuant hereto until
such Contributor Partner has paid to the General Partner or the Partnership, as
the case may be, the amount of such tax or has provided evidence, in form
reasonably satisfactory to the General Partner or the Partnership, as the case
may be, as to the payment thereof.

                                       8
<PAGE>
 
     6.   Anti-Dilution and Adjustment Provisions.  

     (a)  The Conversion Factor shall be adjusted in the event that the General
Partner (i) declares or pays a dividend on its outstanding Shares in Shares or
makes a distribution to all holders of its outstanding Shares in Shares, (ii)
subdivides its outstanding Shares, or (iii) combines its outstanding Shares into
a smaller number of Shares. The Conversion Factor shall be adjusted by
multiplying the Conversion Factor by a fraction, the numerator of which shall be
the number of Shares issued and outstanding on the record date for such
dividend, distribution, subdivision or combination (assuming for such purposes
that such dividend, distribution, subdivision or combination has occurred as of
such time) and the denominator of which shall be the actual number of Shares
(determined without the above assumption) issued and outstanding on the record
date for such dividend, distribution, subdivision or combination. Any adjustment
to the Conversion Factor shall become effective immediately after the effective
date of such event retroactive to the record date, if any, for such event.

     (b)  If at any time the General Partner grants to its stockholders any
right to subscribe pro rata for additional securities of the General Partner,
whether Common Stock or other classifications, or for any other securities or
interests that Contributing Partner would have been entitled to subscribe for
if, immediately prior to such grant, Contributing Partner had exercised its
Redemption Rights and received the Share Purchase Price in payment thereof, in
lieu of any adjustment under any other subsection of this Section 6 or other
provision of this Agreement, then the General Partner also shall grant to
Contributing Partner the same subscription rights that Contributing Partner
would be entitled to if Contributing Partner had exercised its Redemption Rights
in full and received the Share Purchase Price in satisfaction thereof prior to
such grant.

     (c)  Upon the occurrence of a Major Transaction Event where at least one-
half of the value (as determined in good faith by the General Partner) of the
consideration received by the stockholders of the General Partner in connection
with such Major Transaction Event is in the form of securities in a successor
entity, the General Partner shall cause effective provision to be made so that,
upon exercise of the Redemption Rights and payment of the Purchase Price at any
time following such Major Transaction Event by means of the Share Purchase
Price, Unitholders shall have the right to acquire, in lieu of

                                       9
<PAGE>
 
the Shares which otherwise would have been issued to Contributing Partner, the
kind and amount of shares of stock and other securities and property (and the
provisions contained in Section 4.1 shall apply anew to the extent that such
securities are of a class of securities of the General Partner or its successor
that are registered under the Exchange Act) and interests as would be issued or
payable with respect to or in exchange for the number of Shares constituting the
Share Purchase Price as if such Redemption Rights had been exercised and the
General Partner had satisfied the Redemption Rights by delivery of the Share
Purchase Price immediately before such Major Transaction Event.

     (d)  In the event of any other Major Transaction Event, each Unitholder
shall be entitled to exercise the Redemption Rights in full prior to the
consummation of such Major Transaction Event, and, with respect to any Shares
acquired upon exercise thereof, shall be entitled to all of the rights of the
other holders of Shares with respect to any distribution by the General Partner
(or the other party to such Major Transaction Event) in connection with such
Major Transaction Event. If not exercised within forty-five days after written
notice from the General Partner of such Major Transaction Event or such shorter
period between the date of such notice and the effective date of such Major
Transaction Event, the Redemption Rights shall terminate at the expiration of
such period, but the Redemption Rights shall be revived if such Major
Transaction Event is not consummated.

     (e)  The Partnership shall give written notice of any Major Transaction
Event promptly after such Major Transaction is announced to the public.

     (f)  The provisions of this Section 6 shall apply to successive events that
may occur from time to time but only shall apply to a particular event if it
occurs prior to the exercise in full of the Redemption Rights or the liquidation
of the Partnership. Nothing contained herein shall prevent or otherwise limit
the liquidation of the Partnership pursuant to the Partnership Agreement, as
amended from time to time.

     (g)  Whenever the Conversion Factor is adjusted as herein provided, the
General Partner shall compute the adjusted Conversion Factor in accordance with
this Section 6 and shall prepare a certificate signed by the chief financial
officer of the General Partner setting forth the adjusted Conversion Factor and
showing in reasonable detail the facts upon which such

                                       10
<PAGE>
 
adjustment is based, and such certificate shall forthwith be filed at the
offices of the General Partner.

such Units, in accordance with the Partnership Agreement, as amended from time
to time, and delivers to the Partnership a written instrument, in form
