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

     On August 3, 1998, the Company entered into a definitive agreement to make
a series of strategic investments in American Industrial Properties ("AIP")
(NYSE:IND). Under the terms of a share purchase agreement effective July 30, 
1998, the Company purchased 949,147 newly issued common shares for
approximately $14.7 million.  Under the terms of a separate agreement, also
effective as of July 30, 1998, the Company acquired an additional 1,258,471
newly issued AIP shares  in exchange for five light industrial properties
valued at approximately $19.5 million.  Concurrent with entering into the
agreements, AIP appointed Scott A. Wolstein as chairman of its Board of Trust
Managers and three additional designees of the Company to newly created
positions on its Board of Trust Managers.

     On November 20, 1998, the shareholders of AIP approved additional purchases
by the Company of up to 5,226,583 newly issued shares of AIP for approximately
$81.0 million. The Company purchased 2,815,192 of these additional shares for   
approximately $43.6 million on November 20, 1998. Combined, the acquired shares
represent 31.7% of AIP's outstanding shares. Pursuant to the agreement, AIP
may, under certain circumstances and subject to certain limitations, exercise a
put right that would require the Company to purchase additional common or
convertible preferred shares of AIP, not to exceed $200 million, at a price not
to exceed $15.50 and $14.00 per share, respectively.  AIP can only exercise its
right to put these additional shares for the purpose of financing property
acquisitions approved by AIP's  Board of Trust Managers.


Item 7.  Financial Statements, Pro Forma Financial Information and Exhibits
- ---------------------------------------------------------------------------

     This Form 8-K is being filed to update the pro forma financial information
filed in the Company's report on Form 8-K dated April 28, 1998 through the nine
month period ended September 30, 1998. The Company's acquisitions have been
reported on Forms 8-K dated July 1, 1998 and July 16, 1998.

     In addition to the acquisitions previously reported, the Company, on
September 10, 1998, formed a joint venture with the institutional investment
advisory firm DRA Advisors, Inc. ("DRA"), which is acting on behalf of          
institutional clients. In conjunction with the formation of this joint venture, 
the Company contributed six existing shopping center properties valued at
approximately $238 million, with a net book value of $219 million. The Company
received, in exchange for the six properties contributed, a 50% equity
ownership interest in the joint venture and cash of approximately $192 million,
funded from debt and equity proceeds received as described below, which was
used to repay variable rate indebtedness on the Company's revolving credit
facilities. Simultaneously with the Company's contribution, the joint venture
entered into a seven year, $156 million mortgage with interest at a coupon rate
of 6.64% and DRA contributed cash of approximately $42 million in exchange for
a 50% equity interest. The Company also agreed to master lease certain space
occupied by tenants which have filed for bankruptcy under Chapter 11 with
annual base rent of $2.3 million. In exchange for the agreement to master lease
the space, the Company retained all rights associated with the bankruptcy claim
and to the benefits associated with the releasing, if applicable, of the
existing space. The Company does not believe that its exposure to loss is
material under the terms of the agreement. In accordance with the Joint Venture
agreement, the Company will continue to manage the properties and receive
management fees at market rates. The properties contributed to the joint
venture are as follows:

          -    Arrowhead Crossing - Peoria, Arizona (Phoenix)
          -    Foothills Towne Center - Ahwatukee, Arizona (Phoenix)
          -    Eagan Promenade - Eagan, Minnesota (Minneapolis)
          -    Maple Grove Crossing - Maple Grove, Minnesota (Minneapolis)
          -    Eastchase Market - Fort Worth, Texas
          -    Tanasbourne Town Center - Hillsboro, Oregon (Portland)

Financial Statements
- --------------------

The statements of revenue and certain expenses included in this report encompass
the following:

- -         Statements of revenue and certain expenses (unaudited) for the six
          months ended June 30, 1998 and 1997 for the following operating

          -         The Family Center Properties (Acquired Properties)
          -         The Sansone Properties (Acquired Properties)

                    The operating results for three shopping centers under
          development and six shopping center expansions acquired together with
          the purchase of The Family Center Properties are not reflected in the
          accompanying combined statement of revenue and certain expenses of The
          Family Center Properties as no financial information existed for the
          six month period ended June 30, 1998 and 1997. In addition, five
          shopping centers acquired together with the purchase of The Sansone
          Properties are not included in the accompanying combined statement of
   3
          revenue and certain expenses of The Sansone Properties since these
          centers were under development or in the lease-up-phase. Subsequent to
          the Company's purchase, two of The Sansone Properties were sold to one
          of the principal sellers.

                    As noted below, financial statements (audited) for the year
          ended December 31, 1997 for these properties were presented in the
          Company's Form 8-K dated April 28, 1998.

- -         A statement of revenue and certain expenses (unaudited) for the six
          months ended June 30, 1998 and 1997 is not presented for Tanasbourne,
          Oregon (Acquired Property) because the property was in the final
          development stage, and accordingly, the related historical operating
          information would not be meaningful.

Pro Forma Financial Information (unaudited)
- -------------------------------------------

Unaudited pro forma financial information for the Company is presented as
follows:

- -         Pro forma condensed consolidated statement of operations for the nine

- -         Estimated twelve-month pro forma statement of taxable net operating
          income and operating funds available for the year ended December 31,

there are no adjustments for the aforementioned transactions to be made to the
September 30, 1998 balance sheet filed in the Company's Form 10-Q, as of that
date.

1.       OPERATIONS
         ----------

         For purposes of the accompanying combined statement of revenue and
certain expenses, The Family Center Properties represent certain shopping center
properties and one office property ("Properties"), and their management
operations which Developers Diversified Realty Corporation (the "Company")
acquired on July 1, 1998. A summary of the Properties is as follows:



                    NAME OF PROPERTY                             LOCATION           YEAR BUILT
         ---------------------------------------        ------------------------    ----------
                                                                                     
         Family Center at Midvalley, South Phase            Taylorsville, UT              1982
         Family Center at Midvalley, North Phase            Taylorsville, UT              1992
         Family Center at Fort Union, Phases I&II           Midvale, UT                   1973
         Family Center at Fort Union, Phases III            Midvale, UT                   1995
         Family Center at Riverdale, North Phase            Riverdale, UT                 1991
         Family Center at Riverdale, South Phase            Riverdale, UT                 1995
         Hermes Building Office Complex                     Salt Lake City, UT            1986
         Family Center at Orem                              Orem, UT                      1992
         Family Center at Ogden 5-Points                    Ogden, UT                     1977
         Family Center at 33rd South                        Salt Lake City, UT            1978
         Family Place at Logan                              Logan, UT                     1973
         Family Center at Las Vegas                         Las Vegas, NV                 1973
         Family Center at Rapid City                        Rapid City, UT                1978


         A combined statement of revenue and certain expenses has been presented
because the Properties have varying ownership interests in common, are under
common control and management and were purchased through a single transaction.

         The operating results of three shopping centers under development and
six shopping center expansions at the above listed properties, although forming
part of the same transaction with the Company, are not reflected in the
accompanying combined statement of revenue and certain expenses as no historical
financial information exists.

2.       SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
         ------------------------------------------

BASIS OF PRESENTATION
- ---------------------

         The accompanying combined statement of revenue and certain expenses has
been prepared on the accrual basis of accounting.

DEVELOPERS DIVERSIFIED REALTY CORPORATION
THE FAMILY CENTER PROPERTIES
NOTES TO COMBINED STATEMENT OF REVENUE AND CERTAIN EXPENSES
- -----------------------------------------------------------
(Unaudited)

The accompanying combined financial statement is not representative of the
actual operations for the periods presented, as certain revenues and expenses,
which may not be comparable to the revenues and expenses expected to be earned
or incurred by the Company in the future operations of the Properties, have
been excluded. Revenues excluded consist of interest and other revenues
unrelated to the continuing operations of the Properties. Expenses excluded     
consist of depreciation on the building and improvements, amortization of
intangible assets, interest expense and certain professional fees and
administrative costs not directly related to the future operations of the
Properties, primarily payroll associated with the former principals of the
Properties.

INCOME RECOGNITION
- ------------------

         Rental income is recorded on the straight line basis.

CONCENTRATION OF RISK
- ---------------------

         The Family Center Properties' tenant base includes primarily national
and regional retail chains and local retailers, consequently, the Properties'
credit risk is concentrated in the retail industry. There are no tenants which
individually represented greater than 10% of combined revenues.

GENERAL AND ADMINISTRATIVE EXPENSES
- -----------------------------------

         Included in general and administrative expenses are costs associated
with the property management operations.

INTERIM STATEMENTS
- ------------------

         The interim financial data for the six months ended June 30, 1998 and
1997 is unaudited; however, in the opinion of the Company, the interim data
includes all adjustments, consisting only of normal recurring adjustments,
necessary for a fair statement of the results for the interim periods. The
results for the periods presented are not necessarily indicative of the results
for the full year.

USE OF ESTIMATES
- ----------------

         The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amount of revenues and expenses during the
reporting period. Actual results could differ from those estimates.

1.       OPERATION OF PROPERTIES
         -----------------------

         For purposes of the accompanying combined statement of revenue and
certain expenses, The Sansone Properties (the "Properties") represent certain
shopping center properties which Developers Diversified Realty Corporation (the
"Company") acquired on July 16, 1998. A summary of the Properties is as follows:



                    NAME OF PROPERTY                             LOCATION           YEAR BUILT
         ---------------------------------------        ------------------------    ----------
                                                                                     
         Plaza at Sunset Hill                               St. Louis, MO                 1997
         Northland Square                                   Cedar Rapids, IA              1994
         Olympic Oaks Village                               St. Louis, MO                 1985
         Gravois Village                                    St. Louis, MO                 1983
         Morris Corners                                     Springfield, MO               1989
         Keller Plaza                                       St. Louis, MO                 1988

         Walgreen                                           Brentwood, MO                 1988
         Walgreen Plaza                                     St. Louis, MO                 1988
         Promenade at Brentwood                             St. Louis, MO                 1998


         A combined statement of revenue and certain expenses has been presented
because the Properties have varying ownership interests in common, are under
common control and management and were purchased through a single transaction.

         During the period 1995-1997, Plaza at Sunset Hill was redeveloped and
expanded. The combined statement of revenue and certain expenses for the six
months ended June 30, 1997 reflects the operating results of the expansion for
only a portion of the period. The expansion, representing approximately 30% of
the GLA, was completed in 1997.

         At June 30, 1997, the Promenade at Brentwood was under development and
consequently no operating information is included in the combined statement of
revenue and certain expenses for the six month period then ended. For the six
month period ended June 30, 1998, the center was in the lease up phase and
includes a portion of the operating results as certain phases of the center
were not completed as of January 1, 1998. The center was substantially 
completed at June 30, 1998.

2.   SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
     ------------------------------------------

BASIS OF PRESENTATION
- ---------------------

         The accompanying combined statement of revenue and certain expenses has
been prepared on the accrual basis of accounting.

         The accompanying combined financial statement is not representative of
the actual operations for the periods presented, as certain revenues and
expenses, which may not be comparable to the revenues and expenses expected to
be earned or incurred by the Company in the future operations of the Properties,
have been excluded. Revenues excluded consist of interest and other revenues
unrelated to the continuing operations of the Properties. Expenses excluded
consist of depreciation on the buildings and improvements, amortization of
organization costs and other intangible assets, interest expense, professional
fees, charitable contributions, leasing commissions and other general and
administrative costs not directly related to the future operations of the
Properties.

INCOME RECOGNITION
- ------------------

         Rental income is recorded on the straight line basis.

- -----------------------------------------------------------
(Unaudited)

CONCENTRATION OF RISK
- ---------------------

          The Sansone Properties' tenant base includes primarily national and
regional retail chains and local retailers, consequently, the Properties' credit
risk is concentrated in the retail industry. There are no tenants which
individually represented greater than 10% of combined revenues.

INTERIM STATEMENTS
- ------------------

         The interim financial data for the six months ended June 30, 1998 and
1997 is unaudited; however, in the opinion of the Company, the interim data
includes all adjustments, consisting only of normal recurring adjustments,
necessary for a fair statement of the results for the interim periods. The
results for the periods presented are not necessarily indicative of the results
for the full year.

USE OF ESTIMATES
- ----------------

         The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.

3.       RELATED PARTY TRANSACTION
         -------------------------

The Sansone Group, a property management Company controlled by the principals of
The Sansone Properties, provided services to the Properties for all periods
presented. The management fee is determined on a property by property basis
pursuant to property management contracts which generally provide for a
management fee calculated as 5% of rental revenue. The Company acquired a 50%
interest in The Sansone Group and plans to retain the management services
provided to the Properties. Such management fees are included in operating and
maintenance expenses in the accompanying combined statement of revenues and
certain expenses and aggregated approximately $191,000 and $244,000 for the 
period ended June 30, 1997 and June 30, 1998, respectively.

4.       COMMITMENTS
         -----------

The Morris Corners Property is subject to a ground lease requiring payments of
$19,978 per month through December 31, 2015.

                  (1) Based on the preliminary purchase price allocation, determined depreciation 
                  utilizing a 31.5 year life for building and calculated interest at the effective 
                  interest rate associated with the mortgage debt assumed.

                  An aggregate interest cost of $313 associated with the purchase of the Company's equity
                  interest in the properties is calculated at the Company's estimated interest rate under its
                  lines of credit.

                  In addition to cash, the Company's purchase price was funded through the issuance of
                  operating partnership units (OP Units) exchangeable, at the option of the Company and under
                  certain circumstances, into 116,892 of the Company's common shares. The minority interest
                  expense associated with the OP Units is estimated to be $49 for the period prior to
                  acquisition.


(c)      Represents the elimination of the minority interest expense and the
         related interest expense incurred by the Company due to the purchase of
         the minority interest in a shopping center located in North Olmsted,
         Ohio in March 1998.

(d)      The general and administrative expenses of the Company have been
         adjusted by $250 to reflect the estimated increased expenses expected
         to be incurred associated with additional operating personnel and
         related costs attributable to the increase in the Company's portfolio
         of properties resulting from acquisitions and development activities.

(e)      Reflects the net increase in interest cost of $315 relating to variable
         rate indebtedness repaid with the proceeds from the sale of the Medium
         Term Notes completed on July 15, 1998. Pro forma interest incurred
         through the date of issuance on the Medium Term Notes is estimated at
         $4,055 and interest savings on the variable rate indebtedness repaid is
         estimated at $3,740.

(f)      Reflects the reduction of interest costs relating to variable rate
         indebtedness effectively repaid with the proceeds from the sale of     
         669,639 common shares (pre split) completed in April 1998.

                  estimated interest rate under its lines of credit and/or the effective interest rate associated with the
                  mortgage debt assumed. No interest expense was presented relating to shopping centers under development and
                  expansion as such interest costs would have been capitalized.

                  In addition, the Company has guaranteed the value of the operating partnership units for the period two years from
                  the date of issuance. The guarantee is determined with reference to the common shares of the Company. The final
                  number of operating partnership units issued as consideration will not be known until after expiration of the
                  guarantee period.

         (5)      Operating results for the Tanasbourne, Oregon shopping center are not presented as this shopping center was under
                  development during the year.

                  allocation at the effective interest rate associated with the mortgage debt assumed.

         (3)      An aggregate interest cost of $1,212 associated with the purchase of the Company's equity interest in these

         the issuance of operating partnership units (OP Units) exchangeable, at
         the option of the Company and under certain circumstances, into 116,892
         of the Company's common shares. The minority interest expense

         of properties resulting from acquisitions and development activities.

         rate indebtedness repaid with the proceeds from the sale of $75 million
         7.125% Pass-through Assets Trust Securities completed in March 1997.
         Pro forma interest is estimated at $1,103 and interest savings on the
         variable rate indebtedness repaid is estimated at $1,037.

(h)      Reflects the reduction of interest costs relating to variable rate
