Item 1.01 Entry into a Material Definitive Agreement.

Business Combination Agreement

On July 27, 2013, Omnicom Group Inc., a New York corporation (the “Company”), and Publicis Groupe S.A., a French société anonyme (“Publicis”), entered into a Business Combination Agreement (the “Agreement”), pursuant to which the Company and Publicis agreed, subject to the terms and conditions of the Agreement, to combine their respective businesses, with Publicis merging with Publicis Omnicom Group N.V., a newly-formed Dutch holding company (“Publicis Omnicom Group”) and the Company merging with a newly-formed subsidiary of Publicis Omnicom Group.

Transaction Overview

Subject to the terms and conditions of the Agreement, Publicis will merge (the “Publicis Merger”) with and into Publicis Omnicom Group, which will be a newly-created company organized under the laws of the Netherlands, with Publicis Omnicom Group being the surviving entity in the Publicis Merger. Immediately after consummation of the Publicis Merger, a corporation to be incorporated under the laws of New York (“Merger Sub”), wholly-owned by Publicis Omnicom Group, will merge (the “Omnicom Merger” and, together with the Publicis Merger, the “Mergers”) with and into the Company, with the Company being the surviving corporation in the Omnicom Merger.

In the Publicis Merger, each issued and outstanding share of Publicis will be exchanged for 1.000000 ordinary share of Publicis Omnicom Group. In addition, prior to completion of the Publicis Merger, Publicis intends to declare and pay a special dividend, in cash, in an amount equal to €1.00 per Publicis share (the “Publicis Transaction Dividend”). In the Omnicom Merger, each share of common stock of the Company will be converted into the right to receive 0.813008 of a Publicis Omnicom Group ordinary share, together with cash in lieu of fractional shares, subject to adjustment to account for certain changes in outstanding shares and certain excluded asset values as set forth in the Agreement. Similarly, prior to completion of the Omnicom Merger, the Company intends to declare and pay a special dividend, in cash, in an amount equal to $2.00 per share of the Company’s common stock (the “Omnicom Transaction Dividend” and, together with the Publicis Transaction Dividend, the “Transaction Dividends”), subject to adjustment to account for certain changes in outstanding shares of the parties and certain excluded asset values, in each case as set forth in the Agreement, and, if necessary, to equalize the cumulative amount of regular dividends paid by the Company after July 27, 2013 with the cumulative amount of regular Publicis dividends paid after July 27, 2013.  However, dividends of up to $0.80 in the aggregate paid in respect of record dates after July 27, 2013 and before the Mergers are not included in this equalization and will be retained by the Company’s shareholders. The Publicis Transaction Dividend is subject to adjustment, if necessary, to equalize the cumulative amount of regular Publicis dividends paid after July 27, 2013 with the cumulative amount of regular dividends paid by the Company after such date, excluding the up to $0.80 per share of regular dividends described above.  The payment of the Transaction Dividends is also subject to applicable law.

Listing and Shares

Publicis Omnicom Group’s ordinary shares are expected to be listed on the New York Stock Exchange and Euronext Paris and traded under the ticker symbol OMC. Publicis Omnicom Group will seek inclusion of the ordinary shares in the S&P 500 and the CAC 40.

Based on the number of Publicis shares and the number of shares of common stock of the Company expected to be outstanding and vested immediately prior to the closing of the Mergers, the Company estimates that, at the closing, former shareholders of Publicis and the Company will own approximately 50.64% and 49.36%, respectively, of Publicis Omnicom Group.

Governance

Publicis Omnicom Group will have a single-tier Board of Directors consisting initially of sixteen directors, including the two Co-Chief Executive Officers, seven directors designated by the Company and seven directors designated by Publicis. Equal representation will be maintained until two-thirds of the Board of Directors of Publicis Omnicom Group votes to change the structure, but in no event earlier than the 2019 Annual Meeting of Publicis Omnicom Group.

Under the terms of Publicis Omnicom Group’s Articles of Association and Rules for the Board of Directors, John D. Wren, who is currently President and Chief Executive Officer of the Company, and Maurice Lévy, who is currently Chief Executive Officer of Publicis, will become the Co-Chief Executive Officers of Publicis Omnicom Group and will serve through an initial integration period of 30 months, after which Mr. Wren will become the sole Chief Executive Officer and Mr. Lévy will become the sole non-executive Chairman.  Neither Chief Executive Officer can be removed by the Board without the approval of two-thirds of the directors.

The non-executive Chairman of Publicis Omnicom Group will initially be Bruce Crawford, currently the Chairman of the Company, and the Vice Chairperson will be Élisabeth Badinter, currently the Chairperson of Publicis.  Approximately one year following the closing of the Mergers, for the next year, the non-executive Chairperson of Publicis Omnicom Group will be Ms. Badinter, and the Vice Chairman will be Mr. Crawford. These roles will alternate annually until Mr. Lévy becomes non-executive Chairman.  Upon stepping down as Co-Chief Executive Officer, Mr. Lévy will become the sole non-executive Chairman of Publicis Omnicom Group.

Conditions to the Mergers

Completion of the transactions contemplated by the Agreement (the “Transactions”) will be subject to the satisfaction or waiver, if legally permitted, of certain conditions including (a) approval and adoption of the Agreement and the Omnicom Merger by the holders of two-thirds of the outstanding shares of common stock of the Company, approval of the Cross-Border Merger Terms (as described in the Agreement) and the Publicis Merger by the holders of two-thirds of the voting rights attached to the Publicis shares, and the approval of the Publicis Transaction Dividend by the holders of a majority of the voting rights attached to the Publicis shares; (b) approval by requisite governmental regulators and authorities, including approvals under applicable competition laws; (c) the listing of the Publicis Omnicom Group ordinary shares on applicable stock exchanges; (d) the absence of any law or order prohibiting the completion of the Transactions; and (e) the absence of a material adverse effect on either the Company or Publicis.

Other Terms of the Agreement

The Agreement contains mutual customary representations and warranties of the Company and Publicis relating to their respective businesses and public filings. The Agreement also contains customary mutual pre-closing covenants, including the obligation of the Company and Publicis to conduct their businesses in the ordinary and usual course consistent with past practice and to refrain from taking specified actions without the consent of the other party. Each party has agreed not to (a) solicit proposals or enter into agreements relating to alternative acquisition transactions or (b) subject to certain exceptions, enter into discussions concerning, or to provide confidential information in connection with, any proposals for alternative acquisition transactions.

The Agreement contains termination rights for the Company and Publicis applicable upon (a) a final, binding and non-appealable denial of required regulatory approvals; (b) the first anniversary of the date of the Agreement, subject to the right of either party to extend such time period until the eighteen-month anniversary to allow for satisfaction of specified conditions to the closing of the Transactions; (c) the failure of either the Company’s shareholders or Publicis’s shareholders to approve the relevant Transactions by the required vote; (d) a breach by the other party that cannot be cured within 45 days’ notice of such breach, if such breach would result in a failure of the conditions to closing set forth in the Agreement; and (e) a change in recommendation relating to the Transactions by the other party’s Board of Directors.

The Agreement, the form of Publicis Omnicom Group’s Articles of Association and the form of Rules for the Board of Directors of Publicis Omnicom Group are attached hereto as Exhibits 2.1, 99.1 and 99.2, respectively, and are incorporated herein by reference. The foregoing summary does not purport to be complete and is qualified in its entirety by reference to such documents.

Voting Agreements

Ms. Badinter and certain family members, as well as Mr. Lévy, have entered into a Voting and Support Agreement (the “Publicis Voting Agreement”) for the benefit of the Company, pursuant to which they have agreed, among other things, to vote all of their Publicis shares in favor of the Cross-Border Merger Terms, the Publicis Merger, the Publicis Transaction Dividend and certain other transactions contemplated by the Agreement, and against (a) any acquisition proposal for Publicis; (b) any other transaction that would reasonably be expected to result in the failure of any condition to the Mergers set forth in the Agreement to be satisfied prior to the termination date of the Transactions; or (c) any other transaction that would reasonably be expected to result in a material breach of any covenant, representation or warranty of Publicis set forth in the Agreement. As of July 16, 2013, these shareholders collectively

owned, for purposes of approving the Transactions, approximately 6.5% of the outstanding Publicis shares (representing approximately 11.5% of the voting power of Publicis).

Mr. Crawford, Mr. Wren and Randall J. Weisenburger, Executive Vice President and Chief Financial Officer of the Company, have entered into a Voting and Support Agreement (the “Omnicom Voting Agreement”) for the benefit of Publicis, pursuant to which they have agreed, among other things, to vote all of their shares of the Company’s common stock in favor of the adoption of the Agreement and the Omnicom Merger, and against (a) any acquisition proposal for the Company; (b) any other transaction that would reasonably be expected to result in the failure of any condition to the Mergers set forth in the Agreement to be satisfied prior to the termination date of the Transactions; or (c) any other transaction that would reasonably be expected to result in a material breach of any covenant, representation or warranty of the Company set forth in the Agreement. As of July 22, 2013, these shareholders collectively owned less than 1% of the voting power of the Company.

The Publicis Voting Agreement and the Omnicom Voting Agreement are attached hereto as Exhibits 99.3 and 99.4, respectively, and are incorporated herein by reference. The foregoing summary does not purport to be complete and is qualified in its entirety by reference to such documents.
