Item 5.03. Amendments to Articles of Incorporation or By-Laws; Change in Fiscal Year

(a) On May 24, 2011, the shareholders of Omnicom Group Inc. (the “Company”) approved an amendment to the Certificate of Incorporation adding a new Article XI. The new article allows shareholder action by less than unanimous written consent if the matter is approved by the holders of shares having not less than the minimum number of votes that would be necessary to take such action at a meeting at which all shares entitled to vote on the matter were present and voted.

     On May 24, 2011, the shareholders of the Company also approved amendments to the Articles of Incorporation and By-laws reducing any requirements for a supermajority vote to a simple majority of outstanding shares. The new simple majority voting standard applies to any corporate actions, other than the election of directors, taken by a vote of shareholders at a meeting of shareholders at which a quorum is present. The election of directors will continue to be by a majority voting standard and subject to the Company’s resignation policy in uncontested elections, and a plurality voting standard in contested elections. To eliminate the supermajority voting requirements, shareholders approved the following amendments:

• an amendment to Article 8 of the Certificate of Incorporation to change the voting standards for altering the number of directors constituting the entire Board or removing a director from office from a two-thirds of all outstanding shares standard to a majority of shares voting standard.

• an amendment deleting the existing Article X of the Certificate of Incorporation and replacing it with existing Article XI. The previous Article X provided that a two-thirds vote of all outstanding shares is required to approve the adoption, amendment or repeal of any provision of the By-laws or to amend Article 8 or 9 (relating to director liability) of the Certificate of Incorporation.

• an amendment to Article XI of the Company’s By-laws to change the voting standard for amending, repealing or adopting new by-laws from a two-thirds of all issued and outstanding shares standard to a majority of shares voting standard.

     Under the newly adopted amendment, any by-law may be amended or repealed, in whole or in part, and new by-laws may be adopted, only by (i) the affirmative vote of the holders of a majority of the votes cast for such an action, or (ii) the affirmative vote of a majority of the entire Board of Directors.

     The foregoing summary does not purport to be complete and is qualified in its entirety by reference to the full text of the Certificate of Incorporation and By-laws, as amended, copies of which are filed as Exhibits 3.1 and 3.2 to this report and incorporated herein by reference.

Item 5.07. Submission of Matters to a Vote of Security Holders

(a) The Company held its annual meeting of shareholders (the “Annual Meeting”) on May 24, 2011 in Washington, D.C. At the Annual Meeting, the Company’s shareholders elected 12 individuals to the Board of Directors, approved all proposals and rejected none of the proposals. The proposals are described in more detail in the Proxy Statement.

     Proposal 6

(d) Disclosure Regarding Frequency of Shareholder Advisory Vote on Executive Compensation:

     A majority of the votes cast by shareholders voted, on an advisory basis, to hold an advisory vote to approve executive compensation every year. In line with this recommendation by our shareholders, the Board of Directors has decided that it will include an advisory shareholder vote on executive compensation in its proxy materials every year until the next required advisory vote on the frequency of shareowner votes on executive compensation, which will occur no later than our Annual Meeting of shareholders in 2017.
