                        Amendment No. 6 to Schedule TO

                  This Amendment No. 6 to the Tender Offer Statement on
Schedule TO (the "Schedule TO"), filed initially with the Securities and
Exchange Commission (the "SEC") on October 31, 2001 and later amended on
November 13, 2001, November 19, 2001, November 26, 2001, November 28, 2001 and
November 29, 2001, which also constitutes Amendment No. 1 to the Schedule 13D
filed initially with the SEC on October 24, 2001, relate to the offer by Union
Pacific Corporation, a Utah corporation ("Union Pacific") to exchange each
outstanding share of common stock of Motor Cargo Industries, Inc. ("Motor
Cargo"), no par value (collectively, the "Shares"), for either (i) 0.26 of a
share of common stock, par value $2.50 per share, of Union Pacific ("Union
Pacific Stock"), or (ii) $12.10 in cash, at the election of the holder of each
Share and upon the terms and subject to the conditions set forth in the
Prospectus, dated November 29, 2001 (the "Prospectus") incorporated herein by
reference as Exhibit (a)(13), and in the related Letter of Election and
Transmittal, a copy of which was filed as Exhibit (a)(2) to the Schedule TO
(the Letter of Election and Transmittal together with the Prospectus
collectively constitute the "Offer"). Capitalized terms used herein but not
defined herein shall have the meanings ascribed to them in the Prospectus. All
references to the Preliminary Prospectus shall be deemed to refer to the
Prospectus.

Item 11.          Additional Information.

                  Item 11 of the Schedule TO is hereby amended and
supplemented as follows:

         On November 30, 2001, Union Pacific and Motor Cargo jointly issued a
press release filed as Exhibit (a)(14) hereto announcing the expiration of the
Offer. The Offer expired at midnight, New York City time, on Thursday,
November 29, 2001. All Shares validly tendered (and not properly withdrawn)
prior to the expiration of the Offer have been accepted for exchange and will
be exchanged promptly for either Union Pacific Stock or cash, as per the
election of each tendering Motor Cargo shareholder. Approximately 6,708,800
Motor Cargo shares were tendered in the offer, prior to its expiration, which
constitutes approximately 98.3% of the total number of outstanding shares of
Motor Cargo. In addition, the preliminary count by the exchange agent
indicated that an additional 163,100 Motor Cargo shares were tendered pursuant
to notices of guaranteed delivery.

         Pursuant to the Agreement and Plan of Merger, upon acceptance by
Union Pacific of the Motor Cargo shares, Union Pacific was entitled to appoint
five members to the board of directors of Motor Cargo. Union Pacific has
appointed James R. Young, Carl W. von Bernuth, Mary S. Jones, Joseph E.
O'Connor, Jr. and James J. Theisen, Jr. to serve as members of the board of
Motor Cargo. Except for Marvin L. Friedland and Louis V. Holdener, who have
continued as members of the Motor Cargo board, all former members of the board
of directors of Motor Cargo have resigned. The information set forth in the
above-referenced press release is incorporated herein by reference.

Item 12. Exhibits.

                  Item 12 of the Schedule TO is hereby amended and
supplemented to add the following new exhibit:

certify that the information set forth in this statement is true, complete and
correct.

Union Pacific Announces Acquisition of Shares in Motor Cargo Exchange Offer

OMAHA--November 30, 2001--Union Pacific Corporation (NYSE: UNP) and Motor
Cargo Industries, Inc. (NASDAQ: CRGO) today announced that Union Pacific has
accepted the Motor Cargo shares which were tendered for exchange in the
exchange offer which commenced on October 31, 2001, whereby Union Pacific
offered to exchange, at the election of the Motor Cargo shareholders, each
outstanding share of common stock of Motor Cargo for either 0.26 of a share of
Union Pacific common stock, $12.10 in cash or a combination of both. The offer
was made pursuant to a previously announced Agreement and Plan of Merger,
dated as of October 15, 2001, and a tender offer statement, dated October 31,
2001, as amended.

The offer expired at midnight, New York City time, yesterday, November 29,
2001. All Motor Cargo shares validly tendered, and not properly withdrawn,
prior to the expiration of the offer have been accepted for exchange and will
be exchanged promptly for either Union Pacific common stock or cash, as per
the election of each tendering Motor Cargo shareholder. Approximately
6,708,800 Motor Cargo shares were tendered in the offer, prior to its
expiration, which constitutes approximately 98.3% of the total number of
outstanding shares of Motor Cargo. In addition, the preliminary count by the
exchange agent indicated that an additional 163,100 Motor Cargo shares were
tendered pursuant to notices of guaranteed delivery. Substantially all of the
Motor Cargo shareholders who tendered their shares elected to receive shares
of Union Pacific common stock in the offer.

Pursuant to the Agreement and Plan of Merger, upon acceptance by Union Pacific
of the Motor Cargo shares, Union Pacific was entitled to appoint five members
to the board of directors of Motor Cargo. Union Pacific has appointed James R.
Young, Carl W. von Bernuth, Mary S. Jones, Joseph E. O'Connor, Jr. and James
J. Theisen, Jr. to serve as members of the board of Motor Cargo. Except for
Marvin L. Friedland and Louis V. Holdener, who have continued as members of
the Motor Cargo board, all former members of the board of directors of Motor
Cargo have resigned.

Following the mailing of an information statement to the remaining Motor Cargo
shareholders, Union Pacific intends to merge Motor Cargo with Motor Merger
Co., a wholly-owned subsidiary of Union Pacific. In the merger, the remaining
Motor Cargo shareholders will receive in exchange for each outstanding share
of common stock of Motor Cargo $12.10 in cash.
