THIS AMENDMENT dated as of March 7, 2013 (this “Amendment”), amends the Amended and Restated Rights Agreement, dated as of January 17, 2005, as amended on October 29, 2009, (the “Agreement”), by and between GARDNER DENVER, INC. (the “Company”), a Delaware corporation, and WELLS FARGO BANK, NATIONAL ASSOCIATION (the “Rights Agent”). All capitalized terms used but not defined in this Amendment shall have the meanings ascribed to them in the Agreement.

WHEREAS, RENAISSANCE PARENT CORP., a Delaware corporation (“Parent”), RENAISSANCE ACQUISITION CORP., a Delaware corporation and a direct wholly owned Subsidiary of Parent (“Acquisition Sub”) and the Company are, substantially concurrently herewith, entering into an Agreement and Plan of Merger (the “Merger Agreement”), dated as March 7, 2013, pursuant to which, among other things, Acquisition Sub will be merged with and into the Company, with the Company surviving the merger, on the terms and subject to the conditions set forth in the Merger Agreement (the “Merger”), and each issued and outstanding share of Common Stock outstanding immediately prior to the Merger (other than shares of Common Stock owned by the Company as treasury stock, shares of Common Stock owned, directly or indirectly, by Parent or Acquisition Sub and shares of Company Common Stock as to which holders have properly demanded appraisal pursuant to the Delaware General Corporation Law) shall be cancelled and retired and automatically converted into the right to receive $76 in cash, without interest (the “Merger Consideration”).

WHEREAS, pursuant to resolutions adopted on March 7, 2013 (the “Board Resolutions”), the Board of Directors of the Company has adopted and approved the Merger Agreement;

WHEREAS, Section 27 of the Agreement provides that prior to the Distribution Date, and subject to the penultimate sentence of such Section 27 of the Agreement, the Company and the Rights Agent shall, if the Company so directs, supplement or amend any provision of the Agreement without the approval of any holders of certificates representing shares of Common Stock;

WHEREAS, no Distribution Date has occurred and no person is an Acquiring Person; and
