Reference is made to the Amended and Restated Stockholders Agreement, dated November 20, 2006, (the “Stockholders Agreement”), among Hertz Global Holdings, Inc. (the “Company”) and the stockholders of the Company listed on the signature pages thereto. Capitalized terms used herein but not defined herein shall have their respective meanings set forth in the Stockholders Agreement.

This letter (which may be delivered to you in one or more counterparts) will confirm on behalf of the Stockholders identified in the signature pages hereto, that, from and after the date hereof and notwithstanding anything to the contrary in the Stockholders Agreement, for so long as the Stockholders named in Annex A hereto collectively hold less than 2.5% of the Shares of the Company, each of the undersigned Stockholders waives the provisions of Section 2.4 of the Stockholders Agreement as they apply to Merrill Lynch Ventures L.P. 2001 and CMC-Hertz Partners, L.P., and each of the undersigned Stockholders acknowledges that the provisions of Section 2.4 of the Stockholders Agreement shall cease to be binding upon Merrill Lynch Ventures L.P. 2001 and CMC-Hertz Partners, L.P.

Further, each of the undersigned Stockholders, representing the other Principal Investors entitled to designate a director (as that phrase is used in Section 2.6(ii)(D) of the Stockholders Agreement) consent to and agree that the directors remaining in office shall not decrease the size of the Board of Directors. By acknowledging and accepting the terms of this letter, Merrill confirms that, pursuant to Section 2.6(ii) of the Stockholders Agreement, it no longer has the right to designate a Merrill Nominee, and it is further acknowledged by each of the undersigned that the continuing service of Angel Morales as a member of the Board of Directors of the Company is not in the capacity of a Merrill Nominee.

For the avoidance of doubt, the remaining provisions of the Stockholders Agreement remain in full force and effect.


Very truly yours,
