   determined by adding (a) the product of (i) the 11,354,793 common shares of
   beneficial interest, par value $0.10 per share, of American Industrial
   Properties REIT (the "Common Shares") that are proposed to be acquired in the
   merger and (ii) the merger consideration of $14.16 per Common Share, plus (b)

   exchange for the cancellation of such options, plus (c) $1,338,000 payable to
   holders of dividend equivalent rights ("DERs") in exchange for the
   cancellation of such DERs (collectively, the "Total Consideration"). The
   payment of the filing fee, calculated in accordance with Regulation 240.0-11

                                  INTRODUCTION

     This Amendment No. 6 amends and supplements the Rule 13e-3 Transaction
Statement on Schedule 13E-3 (this "Schedule 13E-3") (as amended by Amendment
Nos. 1 through 5 thereto, the "Transaction Statement") jointly filed by (a)
Developers Diversified Realty Corporation, an Ohio corporation ("DDR"), (b) DDR
Transitory Sub Inc., a Texas corporation and subsidiary of DDR ("DDR Sub"), (c)
Scott A. Wolstein, and (d) American Industrial Properties REIT, a Texas real
estate investment trust and the issuer of the equity securities which are the
subject of the Rule 13e-3 transaction ("AIP"). The Transaction Statement was
filed in connection with the Schedule 14A solicitation of proxies required in
connection with the Agreement and Plan of Merger, dated as of November 1, 2000,
by and among DDR, DDR Sub and AIP (the "Merger Agreement"), pursuant to which it
was agreed that, upon AIP shareholder approval, the non-DDR related shareholders
will receive cash for their shares and DDR Sub will merge into AIP, with AIP
surviving as a wholly-owned subsidiary (except for one share owned by Scott
Wolstein) of DDR (the "Merger Transaction").

     The purpose of this Amendment No. 6 is to file a final amendment to the
Transaction Statement to report the results of the Rule 13e-3 transaction
pursuant to Rule 13e-3(d)(3). Capitalized terms used but not defined herein
shall have the meaning set forth in the Transaction Statement.

ITEM 15. ADDITIONAL INFORMATION.

     On May 14, 2001, the shareholders of AIP approved the Merger Transaction.
On the same date, AIP and DDR filed Certificates of Merger with the Secretary of
State of Texas and the County Clerk of Dallas County, Texas, at which time (i)
DDR Sub was merged with and into AIP, (ii) the AIP common shares then owned by
DDR, DDR Sub and their respective direct and indirect subsidiaries were
canceled, (iii) all other AIP common shares became the right to receive $12.89
per share in cash and (iv) all 10,000 shares in DDR Sub were converted into new
AIP common shares of which 9,999 are owned by DDR and one is owned by Scott A.
Wolstein.

     On May 15, 2001, AIP filed a Certification and Notice of Termination of
Registration on Form 15 with the Securities and Exchange Commission in order to
terminate the registration of the AIP common shares under Section 12(g) of the
Act, in accordance with Rule 12g-4. As of such date, AIP'S duty under Section
15(d) of the Securities Exchange Act of 1934 (the "Act") to file information,
documents and reports required under Section 13 of the Act with respect to its
common shares was suspended pursuant to Rule 12h-3 under the Act. In addition,
the common shares of AIP were delisted from trading on the New York Stock
Exchange ("NYSE") and ceased to trade on the NYSE as of May 15, 2001.
