                        REPORT OF INDEPENDENT ACCOUNTANTS


December 10, 1998

To the Board of Directors and Shareholders of
American Industrial Properties REIT


We have audited the accompanying combined statement of revenue and certain
expenses of The A&A Portfolio Properties, described in Note 1, for the year
ended October 31, 1998. This historical statement is the responsibility of
management. Our responsibility is to express an opinion on this historical
statement based on our audit.

We conducted our audit in accordance with generally accepted auditing standards.
Those standards require that we plan and perform the audit to obtain reasonable
assurance about whether the historical statement is free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the historical statement. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall presentation of the historical
statement. We believe that our audit provides a reasonable basis for our
opinion.

The accompanying combined historical statement is prepared on the basis
described in Note 2, for the purpose of complying with Rule 3-14 of Regulation
S-X of the Securities and Exchange Commission (for inclusion in Form 8-K/A of
American Industrial Properties REIT) and is not intended to be a complete
presentation of the combined revenues and expenses of The A&A Portfolio
Properties.

In our opinion, the combined historical statement referred to above presents
fairly, in all material respects, the combined revenue and certain expenses of
The A&A Portfolio Properties, on the basis described in Note 2, for the year
ended October 31, 1998, in conformity with generally accepted accounting
principles.

AMERICAN INDUSTRIAL PROPERTIES REIT
THE A&A PORTFOLIO PROPERTIES
NOTES TO COMBINED STATEMENT OF REVENUE AND CERTAIN EXPENSES
- -------------------------------------------------------------------------------
1.     OPERATIONS

       For purposes of the accompanying combined statement of revenue and
       certain expenses, The A&A Portfolio Properties represent two light
       industrial properties (the "Properties") comprised of three buildings,
       which American Industrial Properties REIT (the "Trust") acquired in
       October 1998. A summary of the Properties is as follows:




              Name of Property                            Location                            Year Built
              ----------------                            --------                            ----------
                                                                                         
       Battlefield / Virginia, Inc.                       Manassas, VA                        1988 / 1989
       Greenbrier Tech                                    Chesapeake, VA                         1986


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

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 Trust in the future operations
       of the Properties, have been excluded. Revenues excluded consist of
       interest, gains on sales of property, and other revenues unrelated to
       the continuing operations of the Properties. Expenses excluded consist
       of depreciation on the building, financing costs, and other general and
       administrative expenses not directly related to the future operations of
       the Properties.

       Income Recognition
       Rental income is recorded on the straight line basis.

       Concentration of Risk
       The Properties are concentrated in the Manassas, VA and Chesapeake, VA
       area. The principal competitive factors in this market are price,
       location, quality of space, and amenities. The Properties represent a
       small portion of the total similar space in the market and compete with
       other properties for tenants. For the year ended October 31, 1998, 59.3%
       of the combined base rents were derived from the Properties' largest
       tenant, AT&T. AT&T is the sole tenant of the two Battlefield buildings.

       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.

3.     ACQUISITION OF PROPERTIES BY THE TRUST

       On October 14, 1998, the Trust purchased Battlefield and on October 16,
       1998 purchased Greenbrier Tech along with three other light industrial
       properties, located in Virginia and managed by Cambridge, from a group
       of related sellers for an aggregate purchase price of $40,170,000. The
       acquisition of the five properties was funded with $22,421,000 in
       assumed debt and the remainder in borrowings from Developers Diversified
       Realty Corporation, a strategic investor in the Trust. The aggregate
       purchase price related to the Properties was $20,224,000 including
       assumed debt of $12,388,000.

AMERICAN INDUSTRIAL PROPERTIES REIT
THE A&A VIRGINIA PROPERTIES
NOTES TO COMBINED STATEMENT OF REVENUE AND CERTAIN EXPENSES
- -------------------------------------------------------------------------------

1.     OPERATIONS

       For purposes of the accompanying combined statement of revenue and
       certain expenses, The A&A Virginia Properties represents three light
       industrial properties (the "Virginia Properties") comprised of four
       buildings, which American Industrial Properties REIT (the "Trust")
       acquired in October 1998. A summary of the Virginia Properties is as
       follows:




           Name of Property                               Location                           Year Built
           ----------------                               --------                           ---------- 
                                                                                        
       Northpointe B                                      Sterling, VA                           1986
       Northpointe C                                      Sterling, VA                           1987
       Greenbrier Circle                                  Chesapeake, VA                     1981 / 1983


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

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 Trust in the future operations
       of the Virginia Properties, have been excluded. Revenues excluded
       consist of interest and other revenues unrelated to the continuing
       operations of the Virginia Properties. Expenses excluded consist of
       depreciation on the building, financing costs, legal fees, and other
       general and administrative expenses not directly related to the future
       operations of the Virginia Properties.

       Income Recognition
       Rental income is recorded on the straight line basis.

       Concentration of Risk
       The Virginia Properties are concentrated in the Sterling, VA and
       Chesapeake, VA area. The principal competitive factors in this market
       are price, location, quality of space, and amenities. The Virginia
       Properties represent a small portion of the total similar space in the
       market and compete with other properties for tenants. For the year ended

AMERICAN INDUSTRIAL PROPERTIES REIT
THE A&A VIRGINIA PROPERTIES
NOTES TO COMBINED STATEMENT OF REVENUE AND CERTAIN EXPENSES
- -------------------------------------------------------------------------------

       Interim Statements
       The interim financial data for the nine months ended September 30, 1998
       is unaudited; however, in the opinion of the Trust, 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 period 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.

3.     ACQUISITION OF PROPERTIES BY THE TRUST

       On October 16, 1998, the Trust purchased the Virginia Properties along
       with one light industrial property and purchased another light
       industrial property on October 14, 1998, located in Virginia and managed
       by Cambridge, from a group of related sellers for an aggregate purchase
       price of $40,170,000. The acquisition of the five properties was funded
       with $22,421,000 in assumed debt and the remainder in borrowings from
       Developers Diversified Realty Corporation, a strategic investor in the
       Trust. The aggregate purchase price related to the Virginia Properties
       was $19,946,000 including assumed debt of $10,033,000.

reflected in the following Pro Forma Financial Information may differ from the
amounts ultimately determined.

1997 included in the Trust's Annual Report on Form 10-K for the year ended

(A)  Represents the historical financial position of the Trust as of September
     30, 1998.

(B)  Represents adjustments for (i) the acquisition of the A&A Portfolio,
     $22,421 of which was financed with the assumption of existing mortgages on
     the properties, which bear interest at rates ranging from 7.375% to 8.13%
     and mature from October 2004 to March 2016, and $17,749 of which was
     financed with borrowings on the Trust's demand note with DDR (the "DDR
     Note"), which bears interest at 10.25% and (ii) the Other Recent
     Acquisitions, $5,100 of which were financed with borrowings on the Trust's
     acquisition line of credit (the "Credit Facility"), which bears interest at
     the 30 day LIBOR rate plus 1.75% and which matures in one year, $11,910 of
     which was financed with borrowings on the DDR Note, which bears interest at
     10.25%, and 



                                    F-13

     $9,375 which was financed with the proceeds of the sale of 604,838 Common
     Shares to DDR at $15.50 per share.

(C)  Represents adjustments for (i) the probable acquisition, through DDR/Tech
     29 L.P., a limited partnership in which the Trust has a controlling
     ownership interest, of Tech 29, expected to be financed with the assumption
     of existing mortgages of $10,201 on Tech 29, which bear interest at a
     weighted average rate of 8.74% and mature in 2003 and 2006 and the proceeds
     from the sale of 1,034,645 Common Shares to DDR at $15.50 per share and
     (ii) the Other Probable Acquisitions in the amount of $147,100, which are
     expected to be financed with borrowings of $90,500 on the Credit Facility
     and the proceeds from the sale of 3,651,613 Common Shares to DDR at $15.50
     per share. There can be no assurance that the acquisition of Tech 29 or the
     other Probable Acquisitions will occur. In addition, there can be no
     assurance that the Board of Trust Managers will approve the sale of Common
     Shares to DDR related to DDR's $200 million commitment, of which $31,349
     (or 2,022,516 Common Shares), is assumed to be issued. Further, there can
     be no assurance that the Common Shares will be sold for $15.50 per share.

(D)  Represents adjustments for the investment by DDR in the Trust, as approved
     by the Trust's shareholders at the Special Meeting held on November 20,
     1998, and the repayment of borrowings under the DDR Note with proceeds from
     the investment. These adjustments exclude any effect from the option of the
     Trust to require DDR to purchase additional shares to fund property
     acquisitions, as no further probable acquisitions have been identified by
     the Trust, other than as previously disclosed.

(E)  Represents adjustments to reflect the sale of 1,958,003 Common Shares for
     $15.50 per share (or $30,349) to DDR, less estimated costs of issuance of
     $5,761, for the DDR Stock Transaction, the previous issuance of 1,258,471
     Common Shares related to the Merger with a subsidiary of DDR, and the sale
     of 949, 147 Common Shares to DDR, as follows:

(F)  Represents adjustments for the application of the cash proceeds from DDR as
     follows: (i) $17,749 to the DDR Note for the A&A Portfolio and(ii) $4,110
     to the DDR Note for the Other Recent Acquisitions.

(G)  Represents adjustments for payments to management under the Change in
     Control Agreements, including payments equal to 2.5 times each individual
     officer's base salary and targeted bonus.

     No adjustment is required for the vesting of dividend equivalent rights, as
     the amounts have been accrued at September 30, 1998. No compensation
     expense would

     75,000 Shares at $15.00 per share and the options to purchase 326,000
     Shares at $13.625 per share, as the exercise price exceeds the current

(A)  Represents the historical results of operations of the Trust for the nine
     months ended September 30, 1998. Certain reclassifications have been made
     to the historical statements of operations of the Trust for purposes of
     this pro forma financial information presentation.

(B)  Represents adjustments for: (i) the 1998 Acquisitions; (ii) the acquisition
     of the Spieker Portfolio; (iii) the acquisition of Norfolk; (iv) the
     acquisition of the A&A Portfolio; (v) the acquisition of the Acquired
     Properties through the Merger with a subsidiary of DDR and issuance of
     1,258,471 Common Shares to DDR; (vi) the sale to DDR of 949,147 Common
     Shares to DDR at $15.50 per share; and (vii) the acquisition of the Other
     Recent Acquisitions, which are derived from the historical operating
     results of the respective properties, except for depreciation and interest,



                                    F-15

     which are based on the Trust's investment in the acquisitions and method of
     financing the acquisitions.

(C)  Represents adjustments for the probable acquisition of Tech 29 and the
     Other Probable Acquisitions based on historical operating results, except
     for depreciation and interest, which are based on the Trust's investment in
     the acquisitions and method of financing the acquisitions. There can be no
     assurance that the acquisition of Tech 29 or the Other Probable
     Acquisitions will occur.

 (D)  Represents adjustments for the DDR Stock Transaction. Since the intent of
      the pro forma condensed statement of operations is to reflect the expected
      continuing impact of the sale of 949,147 Common Shares to DDR at $15.50
      per share, the acquisition of the Acquired Properties, and the DDR Stock
      Transaction, the one-time adjustment for payments to management under the
      Change in Control Agreements has been excluded. Upon consummation of the
      DDR Stock Transaction, this expense will be recognized on the Trust's
      statements of operations.

(E)  Represents adjustment for depreciation which is calculated based on the
     allocation of the purchase price, with buildings depreciated using the
     straight-line method over a 40-year period.

(F)  Represents adjustments for interest expense related to mortgages assumed
     and borrowings under the Trust's Credit Facility and the DDR Note in
     connection with the purchase of the 1998 Acquisitions, the Spieker
     Portfolio, Norfolk, the A&A Portfolio, the Acquired Properties and the
     Other Recent Acquisitions, offset by the reduction in interest expense
     incurred under the DDR Note which was repaid with proceeds received from
     the sale of 949,147 Shares to DDR at $15.50 per share. The assumed
     mortgages bear interest at fixed rates ranging from 7.28% to 8.13%, the
     Credit Facility bears interest at a floating rate of the average 30-day
     LIBOR rate plus 1.75%, and the DDR Note bears interest at a fixed rate of
     10.25%.

(G)  Represents adjustments for interest expense related to mortgages assumed
     and borrowings under the Trust's Credit Facility in connection with the
     purchase of Tech 29 and the Other Probable Acquisitions. The assumed
     mortgages have a weighted average interest rate of 8.74%, and the Credit
     Facility bears interest at a floating rate of the average 30-day LIBOR rate
     plus 1.75%.

(H)  Represents adjustments for the reduction in interest expense from the
     repayment of notes with proceeds received from the sale of 1,958,003 Common
     Shares to DDR for net proceeds of $21,859, as follows: (i) $17,749 to the
     DDR Note for the A&A Portfolio and (ii) $4,110 to the DDR Note for the
     Other Recent Acquisitions.

(I)  The pro forma weighted average shares outstanding include 18,000 weighted
     average Common Shares related to the 27,000 restricted shares issued to
     members of management on April 1, 1998, which become fully vested under the
     terms of the 



                                    F-16

     Change in Control Agreements. The pro forma weighted average shares
     outstanding -- diluted is the same as the pro forma weighted average shares
     outstanding -- basic upon full vesting of the restricted Shares. Excluded
     from the weighted average shares outstanding -- diluted are outstanding
     options to acquire Common Shares which have an exercise price greater than
     the average market price per Common Share during the period and, therefore,
     their effect would be antidilutive; nor are partnership units in the
     operating partnerships included in the weighted average shares outstanding
     -- diluted as their effective would be antidilutive. In addition, these
     adjustments exclude any effect from the option of the Trust to require DDR
     to purchase additional shares to fund property acquisitions, as no further
     probable acquisitions have been identified by the Trust.

     by reference, for the source of the Trust's pro forma statement of
     operations for the year ended December 31, 1997, which gives pro forma
     effect to the following transactions as if the transactions had occurred on
     January 1, 1997:

     (i)   the acquisition of 15 industrial real estate properties;

     (ii)  the sale of two industrial real estate properties;

     (iii) the merger with four publicly traded real estate limited
           partnerships;

     (iv)  the acquisition of the Spieker Portfolio;

     (v)   the acquisition of North Austin; and

     (vi)  the acquisition, through AIP Operating, L.P., a limited partnership
           in which the Trust has a 99% controlling ownership interest, of
           Spring Valley #6.

(B)  Represents adjustments for: (i) the 1998 Acquisitions; (ii) the acquisition
     of the Spieker Portfolio; (iii) the acquisition of Norfolk; (iv) the
     acquisition of the A&A Portfolio; (v) the acquisition of the Acquired

     allocation of the purchase price, with buildings depreciated using the
     straight-line method over a 40-year period.

(F)  Represents adjustments for interest expense related to mortgages assumed
     and borrowings under the Trust's Credit Facility and the DDR Note in
     connection with the purchase of the 1998 Acquisitions, the Spieker
     Portfolio, Norfolk, the A&A Portfolio, the Acquired Properties and the
     Other Recent Acquisitions, offset by the reduction in interest expense
     incurred under the DDR Note, which was repaid with proceeds received from
     the sale of 949,147 Shares to DDR at $15.50 per share. The assumed
     mortgages bear interest at fixed rates ranging from 7.28% to 8.13%, the
     Credit 


   22


     Facility bears interest at a floating rate of the average 30-day LIBOR rate
     plus 1.75%, and the DDR Note bears interest at a fixed rate of 10.25%.

(G)  Represents adjustments for interest expense related to mortgages assumed
     and borrowings under the Trust's Credit Facility in connection with the
     purchase of Tech 29 and the Other Probable Acquisitions. The assumed
     mortgages have a weighted average interest rate of 8.74%, and the Credit
     Facility bears interest at a floating rate of the average 30-day LIBOR rate
     plus 1.75%.

(H)  Represents adjustments for the reduction in interest expense from the
     repayment of notes with proceeds received from the sale of 1,958,003 Common
     Shares to DDR for net proceeds of $21,859, as follows: (i) $17,749 to the
     DDR Note for the A&A Portfolio and (ii) $4,110 to the DDR Note for the
     Other Recent Acquisitions.

(I)  The pro forma weighted average shares outstanding include 27,000 restricted
     Common Shares issued to members of management on April 1, 1998, which
     become fully vested under the terms of the Change in Control Agreements.
     The pro forma weighted average shares outstanding -- diluted equal the pro
     forma weighted average shares outstanding -- basic upon full vesting of the
     restricted shares. Excluded from the weighted average shares outstanding
     are outstanding options to acquire Common Shares which have an exercise
     price greater than the average market price per Common Share during the
     period and, therefore, their effect would be antidilutive; nor are
     partnership units in the operating partnerships included in the weighted
     average shares outstanding as their effect would be antidilutive. In
     addition, these adjustments exclude any effect from the option of the Trust
     to require DDR to purchase additional shares to fund property acquisitions,
     as no further probable acquisitions have been identified by the Trust.
