        On August 8, 2008, in connection with a consent solicitation commenced on July 30, 2008, Omnicom Group Inc. (“Omnicom”), Omnicom Capital Inc. (“Capital”), Omnicom Finance Inc. (together with Omnicom and Capital, the “Issuers”) and Deutsche Bank Trust Company Americas, as trustee (the “Trustee”) entered into a Fifth Supplemental Indenture (the “Fifth Supplemental Indenture”) to the Indenture, dated as of March 6, 2002, between Omnicom and the Trustee (as successor to JPMorgan Chase Bank), as amended by the First Supplemental Indenture, dated as of February 13, 2004, among the Issuers and the Trustee, the Second Supplemental Indenture, dated as of August 12, 2004, among the Issuers and the Trustee, the Third Supplemental Indenture, dated as of November 4, 2004, among the Issuers and the Trustee and the Fourth Supplemental Indenture, dated as of July 10, 2008, among the Issuers and the Trustee (as so amended, the “Indenture”) relating to the Issuers’ Zero Coupon Zero Yield Convertible Notes due 2032 (the “Notes”).

        Pursuant to the Fifth Supplemental Indenture, which is binding on all holders of the Notes that consented to the amendments, (i) consenting noteholders waived their right to contingent cash interest, if payable, from October 31, 2008 through and including August 1, 2010; and (ii) the Issuers waived their right to redeem the Notes prior to August 2, 2010. Holders of $612,494,000 aggregate principal amount of Notes consented to the foregoing amendments and, accordingly, are bound by the Fifth Supplemental Indenture.
