     (1) execute for and on behalf of the undersigned a Form 3, Form 4 or Form 5
         relating to the securities of Avis Budget Group, Inc., in accordance
         with Section 16(a) of the Securities Exchange Act of 1934 and the rules
         thereunder;

     (2) do and perform any and all acts for and on behalf of the undersigned
         which may be necessary or desirable to complete the execution of such
         Form 3, Form 4 or Form 5 and the timely filing of such form with the
         United States Securities and Exchange Commission and any other
         authority; and

     (3) take any other action of any type whatsoever in connection with the
         foregoing which, in the opinion of such attorney-in-fact, may be of
         benefit to, in the best interest of, or legally required by, the
         undersigned, it being understood that the documents executed by such
         attorney-in-fact on behalf of the undersigned pursuant to this Power of
         Attorney shall be in such form and shall contain such terms and
         conditions as such attorney-in-fact may approve in his or her
         discretion.

The undersigned hereby grants to each such attorney-in-fact full power and
authority to do and perform all and every act and thing whatsoever requisite,
necessary and proper to be done in the exercise of any of the rights and powers
