ITEM 1.01.        ENTRY INTO A MATERIAL DEFINITIVE AGREEMENT.

         On March 8, 2005, Thomas Industries Inc., a Delaware corporation
("Thomas"), entered into an Agreement and Plan of Merger (the "Merger
Agreement") with Gardner Denver, Inc., a Delaware corporation ("Gardner
Denver"), and PT Acquisition Corporation, a Delaware corporation and direct
wholly-owned subsidiary of Gardner Denver (the "Merger Sub"). The Merger
Agreement provides that, upon the terms and subject to the conditions set forth
in the Merger Agreement, the Merger Sub will merge with and into Thomas, with
Thomas continuing as the surviving corporation and a direct wholly-owned
subsidiary of Gardner Denver (the "Merger").

         At the effective time and as a result of the Merger, stockholders of
Thomas will become entitled to receive $40.00 in cash in exchange for each
issued and outstanding share of Thomas common stock. At the effective time of
the Merger, holders of each outstanding stock option, stock appreciation right
and performance share issued under Thomas' equity compensation plans will also
become entitled to receive $40.00 in cash, less the applicable exercise price in
the case of stock options, subject to applicable withholding or other taxes.

         Thomas and Gardner Denver have made customary representations,
warranties and covenants in the Merger Agreement. The completion of the Merger
is subject to approval by the stockholders of Thomas and the satisfaction of
other customary conditions, including antitrust approval from U.S. and foreign
governmental entities.

         The Merger Agreement contains certain termination rights for both
Thomas and Gardner Denver.

         Thomas will be required to pay Gardner Denver a $12 million termination
fee if any of the following occur:

         o        Gardner Denver terminates the Merger Agreement because Thomas'
                  board of directors withdraws its recommendation of the Merger;

         o        the stockholders of Thomas fail to approve the Merger
                  Agreement following the withdrawal by Thomas' board of
                  directors of its recommendation of the Merger; or

         o        Thomas terminates the Merger Agreement to accept a superior
                  alternative transaction proposal.

         Thomas may also be obligated to reimburse Gardner Denver for up to $3
million in transaction expenses if the Merger Agreement is terminated by Gardner
Denver under certain circumstances.

         Gardner Denver may also be obligated to reimburse Thomas a $5 million
if the Merger Agreement is terminated under certain circumstances.




         In connection with entering into the Merger Agreement, Thomas' Board of
Directors approved the Rights Plan Amendment (the "Rights Amendment") to the
Amended and Restated Rights Agreement, dated as of January 5, 1998 and as
amended on February 7, 2001 (the "Rights Agreement"), between the Company and
National City Bank, as Rights Agent. The Rights Amendment is further described
in Item 3.03 below.

         The foregoing description of the Merger and the Merger Agreement does
not purport to be complete and is qualified in its entirety by reference to the
complete text of the Merger Agreement a copy of which is filed as Exhibit 2.1
hereto and incorporated herein by reference.


ITEM 3.03.        MATERIAL MODIFICATION TO RIGHTS OF SECURITY HOLDERS.

         As described in Item 1.01 of this Current Report on Form 8-K, on March
8, 2005, in connection with the Merger, the Company's Board of Directors
authorized and approved the execution of the Rights Amendment in order to render
the Rights Agreement inapplicable to the Merger. The Rights Amendment provides,
among other things, that (i) none of Gardner Denver, the Merger Sub or any of
their affiliates shall be deemed to be an "Acquiring Person" under the Rights
Agreement solely by virtue of the execution and delivery of and/or the
consummation of any of the transactions contemplated by the Merger Agreement,
(ii) none of Gardner Denver, the Merger Sub or any of their affiliates shall be
deemed a "Beneficial Owner" of shares of Thomas' common stock solely by reason
of the execution and delivery of and/or the consummation of any of the
transactions contemplated by the Merger Agreement, and (iii) neither a
"Separation Date" nor a "Stock Acquisition Date" shall be deemed to have
occurred solely as the result of the execution and delivery of and/or the
consummation of any of the transactions contemplated by the Merger Agreement.
The foregoing description of the Rights Amendment does not purport to be
complete and is qualified in its entirety by reference to the complete text of
the Rights Amendment, a copy of which is filed as Exhibit 99.1 hereto and
incorporated herein by reference.


ITEM 5.03.        AMENDMENTS TO ARTICLES OF INCORPORATION OR BYLAWS; CHANGE IN 
                  FISCAL YEAR


         On March 8, 2005, the Company's Board of Directors amended the Bylaws
of the Company so that the Board of Directors could select the date of the
annual meeting of stockholders and the Board of Directors could change the size
of the Board of Directors by Board action. Prior to the amendment, the Bylaws
required that the annual meeting of stockholders be held in either April or May
and that a change in the size of the Board of Directors be made by an amendment
to the Bylaws of the Company.

         A copy of the Bylaws, as amended, will be filed as an exhibit to the
Company's Annual Report on Form 10-K for the year ended December 31, 2004.
