                                   SCHEDULE TO

      This Amendment No. 13 to the Tender Offer Statement on Schedule TO amends
and supplements the statement originally filed on July 9, 2003 (as amended or
supplemented prior to the date hereof, the "Schedule TO") by ArvinMeritor, Inc.,
an Indiana corporation ("Parent"), and Delta Acquisition Corp., a Virginia
corporation and a wholly owned subsidiary of Parent (the "Purchaser"). The
Schedule TO relates to the offer by the Purchaser to purchase (1) all
outstanding shares ("Shares") of common stock, par value $1.00 per share, of
Dana Corporation, a Virginia corporation (the "Company"), and (2) unless and
until validly redeemed by the board of directors of the Company, the associated
rights to purchase shares of Series A Junior Participating Preferred Stock, no
par value, of the Company (the "Rights") issued pursuant to the Rights
Agreement, dated as of April 25, 1996 (as amended from time to time, the "Rights
Agreement"), by and between the Company and Chemical Mellon Shareholder Services
L.L.C., as Rights Agent, at a price of $15.00 per Share, net to the seller in
cash, without interest, upon the terms and subject to the conditions set forth
in the Offer to Purchase, dated July 9, 2003 (as amended or supplemented prior
to the date hereof, the "Offer to Purchase"), and in the related Letter of
Transmittal. Unless the context otherwise requires, all references to the Shares
shall be deemed to include the associated Rights, and all references to the
Rights shall be deemed to include the benefits that may inure to holders of
Rights pursuant to the Rights Agreement. This Amendment No. 13 to the Schedule
TO is being filed on behalf of the Purchaser and Parent.

      Capitalized terms used and not defined herein have the meanings specified
in the Offer to Purchase and the Schedule TO.

      The item numbers and responses thereto below are in accordance with the
requirements of Schedule TO.

ITEM 11. ADDITIONAL INFORMATION


      The Introduction to the Offer to Purchase is hereby amended by deleting
the tenth paragraph of such Introduction (as previously amended) in its entirety
and replacing it with the following:

      "In addition, on July 9, 2003, Parent and the Purchaser commenced an
action against the Company in the United States District Court for the Western
District of Virginia seeking a declaratory judgment that their statements and
disclosures in conjunction with the Offer comply with applicable federal law
(the "Western District of Virginia Action"). On July 25, 2003, Parent and the
Purchaser amended their complaint in the Western District of Virginia Action to
add a claim for a declaratory judgment that the Company's statements and
disclosures in response to, or otherwise relating to, the Offer, including, but
not limited to, its Schedule 14D-9, as amended (the "Schedule 14D-9"), contain
material misrepresentations and omissions, and represent fraudulent, deceptive
or manipulative acts on the part of the Company, in violation of Section 14(e)
of the Exchange Act. Parent and the Purchaser's amended complaint also seeks an
order requiring the Company to correct by public means its material
misstatements and omissions, and its fraudulent, deceptive, or manipulative
acts. Finally, Parent and the Purchaser seek in the amended complaint an
injunction prohibiting the Company from further disseminating false and
misleading statements, from making any additional material misstatements or
omissions, and from committing any other fraudulent, deceptive or manipulative
acts that would further harm the Offer. On August 21, 2003, the Company denied
the material allegations in the amended complaint and brought various
counterclaims against Parent and the Purchaser seeking, among other things, a
declaratory judgment that Parent has violated Sections 14(d) and 14(e) of the
Exchange Act and the rules promulgated thereunder, an order requiring Parent to
file disclosures correcting allegedly materially misleading statements and
omissions and extending the Offer in order to enable the Company's shareholders
to analyze such disclosures, and an order enjoining Parent from pursuing the
Offer. On September 9, 2003, Parent and the Purchaser replied to the Company's
counterclaims by denying the material allegations set forth therein, asserting
affirmative defenses thereto and requesting that the court grant judgment
against such counterclaims and instead grant the relief sought in Parent and the
Purchaser's amended complaint."
