hereinafter set forth and other good and valuable consideration, the receipt
and sufficiency of which is acknowledged, the parties hereby agree as follows:

     I.   All terms not otherwise defined herein shall have the meanings
ascribed to each in the Agreement.

     II.  Section 27 of the Agreement is hereby deleted and replaced by the
following:

27.  TENANT CERTIFICATE CONDITION TO CLOSING.  

     27.1 The following terms have been defined as follows for convenience of
reference:

          (i)  "Tenant Certificate" means a certificate, commonly known as an
estoppel certificate, signed by a tenant with respect to its Lease, either in
the form set forth on Exhibit L hereto or on such other form as is
substantially consistent with the requirements of the tenant's lease for such
certificates.

          (ii) "Seller Tenant Certificate" means a Tenant Certificate signed by
the Seller with respect to a particular Lease for which the Tenant in question
has failed to execute and deliver a Tenant Certificate, in which case the
Seller Tenant Certificate shall be in the form of Exhibit L.

          (iii)     "Qualification" means any assertion in a Tenant Certificate
(whether in the form of Exhibit L or otherwise) or in a Seller Tenant
Certificate of (i) a claim, counterclaim, offset or defense against the
landlord, (ii) a default on the part of the landlord, (iii) unpaid credits,
allowances or other sums due from the landlord prior to the date of the
<PAGE>
estoppel (other than disclosed in Paragraph 12.1 herein or pursuant to a new
lease pursuant to Paragraph 26 herein), (iv) an unfulfilled construction or
other obligation on the part of the landlord prior to the date of estoppel
(other than disclosed in Paragraph 12.1 herein or pursuant to a new lease
pursuant to Paragraph 26 herein), or (v) information which is contrary (in an
adverse respect to the landlord) (x) to the information contained in the rent
roll attached hereto as Exhibit M, or (y) the information pertaining to tenant
allowances and concessions and leasing commissions contained in Paragraph 12.1;

          (iv) "Unacceptable Qualification" means any Qualification other than
the following:

               (a)  a Qualification which is expressly disclosed on the rent
roll attached hereto as Exhibit M or a Qualification relating to non-payment of
October, 1996, November, 1996, December, 1996, or January, 1997 rent, provided
the same is not as a result of a default by Landlord; or

               (b)  a Qualification expressly disclosed in this Agreement or
the Exhibits hereto.

     27.2 If a Qualification is not an Unacceptable Qualification, it shall not
affect Purchaser's obligations to close hereunder or give rise to any liability
from Seller to Purchaser.

     27.3 Seller shall promptly request a Tenant Certificate in the form of
Exhibit L from all tenants, and shall vigorously, in good faith, pursue the
collection of the same.  Seller shall deliver to Purchaser, upon Seller's
receipt thereof, all Tenant Certificates signed by tenants (whether in the form
of Exhibit L or otherwise).  Purchaser shall have the right to assist Seller in
obtaining the Tenant Certificates.

     27.4 It shall be a condition to Purchaser's obligations hereunder (the
"Estoppel Condition") that Seller deliver to Purchaser, at or prior to 5:00
p.m. Chicago time on February 10, 1997 (i) a Tenant Certificate from Eckerds
and Publix and (ii) either a Tenant Certificate or a Seller Tenant Certificate
from tenants occupying at least 75% of the occupied leasable area of the
Property after excluding the leasable area of Eckerds and Publix.  Seller shall
be required to deliver to Purchaser all Tenant Certificates received by Seller
from the tenants at the Property.  Notwithstanding the foregoing to the
contrary, Seller shall not have satisfied the Estoppel Condition if any of the
Tenant Certificates or Seller Tenant Certificates received by Seller, disclose
Unacceptable Qualifications other than Unacceptable Qualifications with an
"Estoppel Qualification Sum" (hereinafter defined) of less than $50,000 in the
aggregate.  The "Estoppel Qualification Sum" shall mean the following:

          (i)  if the claim asserted arises out of a defect which can be cured,
with the expenditure of money on a one time basis, such as a physical defect,
then such sum shall be calculated by a reasonable estimate of the cost to
repair or remediate said defect; and
<PAGE>
          (ii) if the claim asserted affects a continuing obligation of a
tenant under the lease, such as the payment of rent, then the claim shall be
calculated by (i) determining the amount of the claim on a per annum basis,
(ii) multiplying said amount by the number of years or partial years said claim
would affect the monetary obligations under the lease and (iii) discounting
said product on a present value basis using a discount rate of 10% per annum.

     If the Unacceptable Qualifications have an Estoppel Qualification Sum of
less than $50,000 in the aggregate, then Seller shall either (i) grant
Purchaser a credit at Closing for an amount equal to the Estoppel Qualification
Sum, or (ii) cure all conditions giving rise to an Unacceptable Qualification
on or before the Closing.  The determination to perform the covenant contained
in subparagraphs (i) or (ii) in the preceding sentence shall be made by Seller.
Provided Seller performs its covenant in this Paragraph 27.4, the disclosure of
Unacceptable Qualifications having an Estoppel Qualification Sum of less than
$50,000 in the aggregate shall not affect Purchaser's obligations to close
hereunder or give rise to any additional liability from Seller to Purchaser.

     27.5 If Seller delivers any Tenant Certificates containing no Unacceptable
Qualifications after Closing to Purchaser containing all of the information
herein required from a tenant under a Lease for whom Seller has executed and
delivered a Seller Tenant Certificate at Closing, the Seller Tenant Certificate
executed and delivered by Seller at Closing shall become null and void and the
Tenant Certificate received from the tenant shall be substituted therefor.  All
Seller Tenant Certificates shall be to the "knowledge of Seller" as such phrase
is defined in paragraph 16.1 in the Agreement.  Seller's liability under all
such Seller Tenant Certificates delivered to Purchaser shall be limited to
$50,000 in the aggregate.

     27.6 If Seller has not satisfied the Estoppel Condition on or before 5:00
p.m. Chicago time on February 10, 1997, then Purchaser shall have the right to
terminate this Agreement by delivering written notice to Seller on or before
5:00 p.m. Chicago time on February 14, 1997.  If Purchaser exercises its rights
to terminate in accordance with the terms of this Paragraph 27.5, this
Agreement shall be null and void without further action of the parties and all
Earnest Money theretofore deposited by Purchaser together with any interest
accrued thereon, shall be returned to Purchaser, and neither party shall have
any further liability to the other, except for Purchaser's obligation to
indemnify Seller and restore the Property, as more fully set forth in Paragraph
7 hereof.  If Purchaser does not terminate this Agreement pursuant to the first
sentence of this Paragraph 27.6, the parties shall proceed to Closing and (i)
Purchaser shall receive a credit at Closing equal to the amount of the Estoppel
Qualification Sum of the Unacceptable Qualifications contained in the Tenant
Certificates, up to an aggregate amount of $50,000 or (ii) Seller shall cure
all conditions giving rise to an Unacceptable Qualification Sum up to an
aggregate amount of $50,000.  The determination to perform the covenant
contained in subparagraphs (i) or (ii) in the preceding sentence shall be made
by Seller.
<PAGE>
     27.7 Notwithstanding anything contained herein to the contrary, if Seller
does not satisfy the Estoppel Condition because the estoppel qualification sum
exceeds $50,000 and Purchaser has terminated the Agreement pursuant to
Paragraph 27.6, Seller shall have the right to vitiate Purchaser's termination
by written notice on or before 5:00 p.m. Chicago time on February 19, 1997 in
which case the parties shall proceed to Closing and Seller shall either (i)
grant Purchaser at Closing for an amount to the Estoppel Qualification Sum or
(ii) cure all conditions giving rise to an Unacceptable Qualification on or
before the Closing.  The determination to perform the covenant contained in
subparagraphs (i) or (ii) in the preceding sentence shall be made by Seller.

     III. Except as amended hereby, the Agreement shall be and remain unchanged
and in full force and effect in accordance with its terms.

     IV.  This Amendment may be executed in counterparts each of which shall be
deemed an original, but all of which, when taken together shall constitute one
and the same instrument.  To facilitate the execution of this Amendment, Seller
and Purchaser may execute and exchange by telephone facsimile counterparts of
the signature pages, with each facsimile being deemed an "original" for all
purposes.


     IN WITNESS WHEREOF, the parties have executed this Amendment as of the
date first set forth above.
