ITEM 5.           OTHER EVENTS.

                  On September 26, 1999, MotivePower Industries, Inc., a
Pennsylvania corporation ("MotivePower"), and Westinghouse Air Brake Company, a
Delaware corporation ("WABCO"), agreed to amend and restate the Agreement and
Plan of Merger dated as of June 2, 1999, as amended as of July 19, 1999, between
MotivePower and WABCO (the "Amended and Restated Merger Agreement") to provide
for the merger of MotivePower with and into WABCO (the "Merger"). In the Merger,
each share of MotivePower Common Stock, par value $0.01 per share (the
"MotivePower Common Stock"), together with any associated MotivePower Right (as
defined in Section 3.2(a) of the Amended and Restated Merger Agreement), not
owned directly or indirectly by MotivePower or WABCO, will be converted into
0.66 shares of WABCO's Common Stock, par value $0.01 per share (the "WABCO
Common Stock"). WABCO and MotivePower issued a joint press release announcing
the execution of the Amended and Restated Merger Agreement on September 27,
1999, a copy of which is filed as Exhibit 99.1 hereto and which is incorporated
herein by reference.

                  The Merger is intended to constitute a tax-free reorganization
under the Internal Revenue Code of 1986, as amended, and will be accounted for
as a pooling of interests.

                  Consummation of the Merger is subject to various conditions,
including: (i) approval and adoption of the Amended and Restated Merger
Agreement and the Merger by the shareholders of each of WABCO and MotivePower;
(ii) registration of the shares of WABCO Common Stock to be issued in the Merger
under the Securities Act of 1933, as amended (the "Securities Act"); (iii)
receipt of opinions of counsel as to the federal tax treatment of certain
aspects of the Merger; and (iv) satisfaction of certain other conditions.

                  The Amended and Restated Merger Agreement and the transactions
contemplated thereby will be submitted for adoption and approval at the meetings
of the shareholders of each of MotivePower and WABCO. Prior to such meetings,
WABCO will file a registration statement with the Securities and Exchange
Commission registering under the Securities Act the WABCO Common Stock to be
issued in the Merger. Such shares of WABCO Common Stock will be offered to
MotivePower shareholders pursuant to a prospectus that will also serve as a
joint proxy statement for the shareholders' meetings.

                  The foregoing summary of the Amended and Restated Merger
Agreement is qualified in its entirety by reference to the text of the Amended
and Restated Merger Agreement, a copy of which is filed as Exhibit 2.1 hereto
and which is incorporated herein by reference.

                  In connection with the execution of the Amended and Restated
Merger Agreement, MotivePower and WABCO agreed to amend and restate the WABCO
Stock Option Agreement dated as of June 2, 1999 (the "Amended and Restated WABCO
Option Agreement"). Under the Amended and Restated WABCO Option Agreement, WABCO
granted MotivePower an option (the "WABCO Option") to purchase up to
approximately 19% of the outstanding shares of WABCO Common Stock (before giving
effect to the WABCO Option) exercisable in

the circumstances specified in the Amended and Restated WABCO Option Agreement.
MotivePower and WABCO also agreed to amend and restate the MotivePower Stock
Option Agreement dated as of June 2, 1999 (the "Amended and Restated MotivePower
Stock Option Agreement"). Under the Amended and Restated MotivePower Option
Agreement, MotivePower granted WABCO an option (the "MotivePower Option") to
purchase up to approximately 19% of the outstanding shares of MotivePower Common
Stock (before giving effect to the MotivePower Option) exercisable in the
circumstances specified in the Amended and Restated MotivePower Option
Agreement.

                  The foregoing summaries of the Amended and Restated WABCO
Option Agreement and the Amended and Restated MotivePower Option Agreement are
qualified in their entirety by reference to the text of such agreements, copies
of which are filed as Exhibits 2.2 and 2.3 hereto and which are incorporated
herein by reference.

                  In connection with the execution of the Amended and Restated
Merger Agreement, Motive Power and certain stockholders of WABCO entered into a
voting agreement dated as of September 26, 1999 (the "WABCO Voting Agreement"),
pursuant to which, subject to limited exceptions, such stockholders have agreed
to vote their shares of WABCO Common Stock in favor of the proposals to approve
and adopt the Merger and the Amended and Restated Merger Agreement and to take
certain other actions. Also in connection with the execution of the Amended and
Restated Merger Agreement, WABCO and John C. Pope, a stockholder of MotivePower,
entered into a voting agreement dated as of September 26, 1999 (the "MotivePower
Voting Agreement"), pursuant to which, subject to limited exceptions, Mr. Pope
has agreed to vote his shares of MotivePower Common Stock in favor of the
proposals to approve and adopt the Merger and the Amended and Restated Merger
Agreement and to take certain other actions.

                  The foregoing summaries of the WABCO Voting Agreement and the
MotivePower Voting Agreement are qualified in their entirety by reference to the
text of such agreements, copies of which are filed as Exhibits 10.1 and 10.2
