                     This Amendment No. 16 ("Amendment No. 16") is filed by
Security Capital Group Incorporated, a Maryland corporation (f/k/a Security
Capital Realty Incorporated) ("Group"), SC Capital Incorporated, a Nevada
corporation ("SC Capital") and a wholly owned subsidiary of Group, SC Realty
Incorporated, a Nevada corporation ("SC-Realty") and a wholly owned subsidiary
of SC Capital, Security Capital Operations Incorporated, a Maryland corporation
("Operations") and a wholly owned subsidiary of SC-Realty, Security Capital
Warehouse Distribution Business Trust, a Maryland real estate investment trust
and a subsidiary of Operations (f/k/a West Mixed-Use Realty Investors Trust)
("West" and, together with Group, SC Capital, SC-Realty and Operations, the
"Original Reporting Persons"), General Electric Company, a New York corporation
("GE"), General Electric Capital Services, Inc., a Delaware corporation ("GECS")
and a wholly owned subsidiary of GE, General Electric Capital Corporation, a
Delaware corporation ("GECC") and a wholly owned subsidiary of GECS, and GE
Capital International Holdings Corporation, a Delaware corporation and a wholly
owned subsidiary of GECC ("GE Holdings" and, together with GE, GECS and GECC,
the "Additional Reporting Persons"). The Additional Reporting Persons and the
Original Reporting Persons are hereinafter referred to collectively as the
"Reporting Persons".

                     This Amendment No. 16 amends the Schedule 13D originally
filed by Group, SECAP Realty Incorporated, Security Capital Group Incorporated,
a Delaware corporation, and William D. Sanders, an individual, on March 11, 1994
(as previously amended, the "Schedule 13D"). This Amendment No. 16 relates to
common shares of beneficial interest, par value $0.01 per share (the "Shares"),
of ProLogis Trust, a Maryland real estate investment trust (f/k/a Security
Capital Industrial Trust) ("ProLogis"). Capitalized terms used herein without
definition shall have the meanings ascribed thereto in the Schedule 13D, as
amended.

ITEM 2.              IDENTITY AND BACKGROUND.

Item 2 of the Schedule 13D hereby is amended as follows:

                     Upon the completion of the Merger of Merger Sub with and
into Group on May 14, 2002, Group survived the Merger and became a wholly owned
subsidiary of GE Holdings. As a result of the Merger, the Additional Reporting
Persons have been added to the Schedule 13D as Reporting Persons.

                     GE Holdings is a Delaware corporation with its principal
executive offices located at 1600 Summer Street, Stamford, Connecticut 06905. GE
Holdings is a holding company which owns all the common stock of Group and other
subsidiaries.

                     GECC, together with its affiliates, operates primarily in
the financing industry and, to a lesser degree, in the life insurance and
property/casualty insurance industries and maintains its principal executive
offices at 260 Long Ridge Road, Stamford, Connecticut 06927.


                                       11

                     GECS is a Delaware corporation with its principal executive
offices located at 260 Long Ridge Road, Stamford, Connecticut 06927. GECS is a
holding company which owns all the common stock of GECC and other subsidiaries.

                     GE is a New York corporation with its principal executive
office located at 3135 Easton Turnpike, Fairfield, Connecticut 06431. GE engages
in providing a wide variety of industrial, commercial and consumer products and
services.

                     For information with respect to the identity and background
of each executive officer and director of each of the Additional Reporting
Persons, see Schedules 1 through 4 (the "Additional Reporting Person Schedules")
which are attached hereto as Exhibit 7 and are hereby incorporated herein by
reference.

                     At the Effective Time of the Merger, the Board of Directors
of Group became comprised of the individual listed on Schedule 5 to Exhibit 7.

                     During the last five years, none of the Additional
Reporting Persons, nor, to the best of their knowledge, any person identified in
the Additional Reporting Person Schedules has been (i) convicted of any criminal
proceeding (excluding traffic violations or similar misdemeanors) or (ii) a
party to a civil proceeding of a judicial or administrative body of competent
jurisdiction and as a result of such proceeding was or is subject to a judgment,
decree or final order enjoining future violations of, or prohibiting or
mandating activities subject to federal or state securities laws or finding any
violation with respect to such laws.

ITEM 4.              PURPOSE OF TRANSACTION.

Item 4 of the Schedule 13D hereby is amended to add the following:

                     On May 14, 2002, at the Group Stockholder Meeting, the
stockholders of Group, by a majority of all votes entitled to be cast, approved
and adopted the Merger Agreement and the Merger. On May 14, 2002, Articles of
Merger (the "Articles of Merger") between Group and Merger Sub were filed with
the State Department of Assessments and Taxation of Maryland. The Merger became
effective as of the date and time of the filing of the Articles of Merger.

                     As part of the merger consideration, 32,530,904 Shares were
distributed by Group at the Effective Time of the Merger pursuant to the Stock
Election. This distribution resulted in Group retaining beneficial ownership of
approximately 9.79% of the outstanding Shares following the Merger.

                     Accordingly, at the Effective Time of the Merger, and for
as long as Group beneficially owns less than 10% of the Shares, Group no longer
has the right to designate any persons for nomination to the ProLogis Board of
Trustees pursuant to the Third Amended and Restated Investor Agreement between
Group and ProLogis (the "Investor Agreement"). Similarly, Group no longer has
approval rights with respect to ProLogis actions, including:


                                       12

         1.       the issuance of equity securities or securities convertible
                  into equity securities (other than issuances in connection
                  with option, dividend reinvestment and similar plans) for less
                  than the fair market value of such securities;

         2.       the issuance of any preferred shares which would result in the
                  fixed charge coverage ratio (as defined in the Investor
                  Agreement) being less than 1.4 to 1.0;

         3.       adopting any employee benefit plans under which common shares
                  may be issued;

         4.       the compensation of ProLogis' senior officers; and

         5.       the incurrence of additional indebtedness which would result
                  in the interest expense coverage ratio (as defined in the
                  Investor Agreement) being less than 2.0 to 1.0.

                     On May 13, 2002, C. Ronald Blankenship and Thomas G.
Wattles, who previously were designees of Group on the ProLogis Board of
Trustees, resigned from the ProLogis Board of Trustees.

                     Group continues to be the beneficial owner of ProLogis
Shares, and any action or discussions taken in such connection will be subject
to and conducted in accordance with all applicable legal rules and contractual
agreements to which Group is subject or which otherwise apply to the purchase or
sale of ProLogis Shares. Subject to these requirements and limitations, however,
Group reserves all of its rights with respect to its investment intent as
previously described in this Schedule 13D.

                     Except as set forth above, the response of the Reporting
Persons to this Item 4 as previously disclosed in the Schedule 13D has not
changed.

ITEM 5.              INTEREST IN SECURITIES OF THE ISSUER.

                     At the Effective Time of the Merger, West owned 17,317,918
Shares, representing approximately 9.79% of the outstanding Shares (based upon
the reported number of outstanding Shares as of April 11, 2002 as stated in
ProLogis' Annual Report on Form 10-K/A for the year ended December 31, 2001).
Operations, SC-Realty, SC Capital, Group and, solely for purposes of Section
13(d) of the Exchange Act and Rule 13d-3 promulgated thereunder, GE Holdings and
GECC, also may be deemed to beneficially own such Shares. However, the filing of
this statement shall not be construed as an admission that GECS or GE are, for
purposes of Section 13(d) of the Exchange Act, or Rule 13d-3 promulgated
thereunder, the beneficial owner of any of the Shares covered by this statement.

                     Except as discussed in Item 4, no transactions in Shares
were effected by any of the Reporting Persons, or, to the best of their
knowledge, any of the persons identified in the Additional Reporting Person
Schedules, during the 60 days prior to the date hereof.
