CORPORATE GOVERNANCE

Board Composition and Leadership; Stock Ownership Guidelines

     Our Board of Directors currently consists of 13 directors: 11 independent or outside directors, our Chairman of the Board (Bruce Crawford) and our President and Chief Executive Officer (John D. Wren). Each director stands for election annually. Biographical information and information about the Committees on which our directors serve is included below in the section entitled “Items To Be Voted On: Item 1 — Election of Directors.”

     We have maintained a separate Chairman of the Board and CEO since January 1, 1997, and we treat those positions as separate and distinct. The CEO is responsible for the overall execution of the Company’s strategy. The Chairman of the Board provides guidance and mentorship to the CEO, and presides over meetings of the full Board. We believe that this leadership structure enhances the accountability of the CEO to the Board and strengthens the Board’s independence from management.

     Our Chairman of the Board, Bruce Crawford, has tremendous experience both with Omnicom and in advertising. He began his career in advertising in 1956 and, in 1963, he joined BBDO Worldwide. He held a variety of high-level positions at BBDO, including that of President and CEO. He was Omnicom’s President and CEO from 1989 until 1995, when he became Omnicom’s Chairman of the Board and CEO. Upon Mr. Wren’s appointment as President and Chief Executive Officer in 1997, Mr. Crawford resigned from his role as CEO, while remaining Chairman of the Board as well as an executive officer. Our Board has determined that Mr. Crawford’s continued role as Chairman of the Board allows us to further benefit from the depth of Mr. Crawford’s prior experience and helps us preserve our distinctive culture and history.

     Mr. Wren is a member of the Board in addition to being our President and CEO. Separating the roles of CEO and Chairman of the Board allows Mr. Wren to focus his efforts on running our business and managing the Company in the best interests of our shareholders.

     We believe our CEO and our Chairman of the Board have an excellent working relationship that has allowed Mr. Wren to focus on our Company’s successful performance. Our Governance Committee oversees the evaluation of the Board and makes recommendations to the Board with respect to the Board’s performance and standards and procedures for review of the Board’s performance. Our Governance Committee is tasked with evaluating and making recommendations to the Board with respect to the functions of our Board committees including their structure, responsibilities, performance and composition.

     Our Board believes that the current Board leadership structure is best for the Company and its shareholders at this time.

     Our outside directors are Alan R. Batkin, Mary C. Choksi, Robert Charles Clark, Leonard S. Coleman, Jr., Errol M. Cook, Susan S. Denison, Michael A. Henning, John R. Murphy, John R. Purcell, Linda Johnson Rice and Gary L. Roubos. Our Board has determined that all of our outside directors are “independent” within the meaning of the rules of the New York Stock Exchange, Inc. (“NYSE”), as well as under our Corporate Governance Guidelines. Our Corporate Governance Guidelines are posted on our website at http://www.omnicomgroup.com. In determining that each of our outside directors is independent, the Board of Directors took into consideration the answers to annual questionnaires completed by each of the directors, which covered any transactions with director-affiliated entities. The Board also considered that Omnicom and its subsidiaries occasionally and in the ordinary course of business, sell products and services to, and/or purchase products and services from, entities (including charitable foundations) with which certain directors are affiliated. The Board determined that these transactions were not material to Omnicom or the entity and that none of our directors had a material interest in the transactions with these entities. The Board therefore determined that none of these relationships impaired the independence of any outside director.

     As a matter of policy, the independent non-management directors regularly meet in executive session, without management present. They met six times in 2011. Our Board has appointed Mr. Purcell, the Chairman of our Governance Committee, to preside over executive sessions of the Board.

     The Board encourages stock ownership by directors and senior executives. Directors may elect to receive some or all of their cash director compensation in our common stock. Information about stock ownership by our directors and executive officers is included below in the section entitled “Stock Ownership”, information about

2

stock ownership guidelines for our named executive officers is included below in the section entitled “Executive Compensation: Compensation Discussion and Analysis”, information about stock ownership guidelines for our directors is included below in the section entitled “Directors’ Compensation for Fiscal 2011.”

Board Operations

     Our Board met six times during 2011. The Board generally conducts specific oversight tasks through Committees so that the Board as a whole can focus on strategic matters and those particular tasks that by law or custom require the attention of the full Board. Our Board has established six standing Committees, functioning in these areas, as explained more fully below:

• audit and financial reporting
• management/compensation
• corporate governance
• finance and acquisitions/divestitures
• attendance to matters requiring consideration between Board meetings
• qualified legal compliance

     Each of the Committees operates under a written charter recommended by the Governance Committee and approved by the Board. The Board operates pursuant to our Corporate Governance Guidelines. Each Board Committee is authorized to retain its own outside advisors. Our Corporate Governance Guidelines and Committee charters that have been approved by the Board are posted on our website at http://www.omnicomgroup.com.

     Audit Committee: The Audit Committee’s purpose is to assist the Board in carrying out its financial reporting and oversight responsibilities, including oversight of risk as described in “Risk Oversight” below. In this regard, the Audit Committee assists the Board in its oversight of (a) the integrity of our financial statements, (b) compliance with legal and regulatory requirements, (c) the qualifications and independence of our independent auditors, and (d) the performance of our internal audit function and independent auditors. Furthermore, the Audit Committee prepares the report included below in the section entitled “Audit Related Matters: Audit Committee Report.” The Audit Committee also has the power to retain or dismiss our independent auditors and to approve their compensation.

     The members of our Audit Committee are Messrs. Murphy (Committee Chair), Clark, Cook and Henning and Ms. Choksi. The Board has determined that each member of our Audit Committee is “independent” within the meaning of the rules of both the NYSE and Rule 10A-3 of the Securities Exchange Act of 1934, as amended. The Board has also determined that each member of our Audit Committee is an “audit committee financial expert,” is “financially literate” and has “accounting or related financial management expertise,” as such qualifications are defined by SEC regulations and the rules of the NYSE, respectively. In addition to being a member of Omnicom’s Audit Committee, Mr. Henning serves on the audit committees of three other public companies. The Board has determined that Mr. Henning’s additional board service does not negatively impact his service to the Omnicom Audit Committee. It is the Board’s opinion that Mr. Henning’s breadth and depth of financial experience and knowledge greatly enhance the abilities and competencies of the Omnicom Audit Committee, and that, as a retiree, Mr. Henning has ample time and capacity to serve such other public company audit committees without impairing his ability to serve Omnicom. In the Board’s opinion, such service actually enhances his ability to serve Omnicom.

     The Audit Committee met 11 times last year.

     Compensation Committee: The Compensation Committee’s purpose is (a) to assist the Board in carrying out its oversight responsibilities relating to compensation matters, including oversight of risk as described in “Risk Oversight” below, (b) to prepare a report on executive compensation for inclusion in our annual Proxy Statement and (c) to administer and approve awards under our equity and other compensation plans. The report of the Compensation Committee is included below in the section entitled “Executive Compensation: Compensation Committee Report.”

3

     None of our Compensation Committee members is a current or former employee or officer of Omnicom or its subsidiaries. None of the Compensation Committee members has ever had any relationship requiring disclosure by Omnicom under Item 404 of the SEC’s Regulation S-K. None of our executive officers serves as a member of the board of directors or compensation committee of any other company that has an executive officer serving as a member of our Board or its Compensation Committee.

     The members of our Compensation Committee are Messrs. Roubos (Committee Chair), Batkin, Coleman and Henning and Mses. Denison and Johnson Rice. The Board has determined that each member of our Compensation Committee is “independent” within the meaning of the rules of the NYSE and a “non-employee director” within the meaning of the regulations of the SEC.

The Compensation Committee met nine times last year.

     Governance Committee: The Governance Committee’s purpose is to assist the Board in carrying out its oversight responsibilities, including oversight of risk as described in “Risk Oversight” below, relating to (a) the composition of the Board and (b) certain corporate governance matters. As part of its responsibilities, the Committee considers and makes recommendations to the full Board with respect to the following matters:

• director nominees and underlying criteria for election to the Board and its Committees;
• the functions of the Board Committees;
• standards and procedures for review of the Board’s performance;
• our corporate governance policies generally, including with respect to director qualification standards, responsibilities, access to management and independent advisors, compensation, orientation and education, and performance evaluation;
• management succession;
• the Code of Conduct applicable to our directors, officers and employees; and
• the Governance Committee’s performance of its own responsibilities.

     The members of our Governance Committee are Messrs. Purcell (Committee Chair), Clark, Coleman and Cook, and Mses. Denison and Johnson Rice. The Board has determined that each member of our Governance Committee is “independent” within the meaning of the rules of the NYSE.

     The Governance Committee met six times last year.

     Nominations for directors at our 2013 Annual Meeting of Shareholders may be made only by the Board or a Board Committee, or by a shareholder entitled to vote who delivers notice along with the additional information and materials required by our By-laws to our Corporate Secretary not later than 60 days prior to the date set for the 2013 Annual Meeting of Shareholders. Our By-laws provide that in order for a nomination to be considered, the notice must include the information as to such nominee and submitting shareholder that would be required to be included in a proxy statement under the proxy rules of the SEC if such shareholder were to solicit proxies from all shareholders of Omnicom for the election of such nominee as a director and if such solicitation were one to which Rules 14a-3 to 14a-12 under the Securities Exchange Act of 1934, as amended, applied. We also may require any proposed nominee to furnish such other information as may be reasonably required to determine whether the proposed nominee is eligible to serve as an independent director or that could be material to a reasonable shareholder’s understanding of the nominee’s independence or lack thereof. You can obtain a copy of the full text of the By-law provision noted above by writing to our Corporate Secretary at our address listed on the cover of this Proxy Statement, or on our website at http://www.omnicomgroup.com. Our By-laws have also been filed with the SEC.

     The Governance Committee will consider all candidates recommended by our shareholders in accordance with the procedures included in our By-laws and this Proxy Statement. We did not receive any nominee recommendations from shareholders this year. Any future director candidate recommendations made by shareholders that are properly submitted will be considered by the Governance Committee in the same manner as those submitted by the Board or the Governance Committee itself.

     Our Board seeks to ensure that it is composed of individuals not only with substantial experience and judgment but also from diverse backgrounds and experiences. In determining the nominees for the Board, our Governance Committee considers the criteria outlined in our Corporate Governance Guidelines including a nominee’s background and experience in relation to other members of the Board, his or her readiness to commit the time required to discharge Board duties and independence issues. In addition, our Governance Committee considers the composition of the Board as a whole and diversity in its broadest sense, including persons diverse in geography, gender and ethnicity as well as representing diverse viewpoints, age, and professional and life experiences. In considering diversity, director nominees are neither chosen nor excluded solely or largely based on any one factor. The Governance Committee considers a broad spectrum of skills and experience to ensure a strong and effective Board.

     Our Governance Committee oversees the evaluation of the Board and makes recommendations to the Board with respect to the Board’s performance and standards and procedures for review of the Board’s performance. Our Governance Committee is tasked with evaluating and making recommendations to the Board with respect to the functions of our Board Committees including their structure, responsibilities, performance and composition.

     The Governance Committee reviews the composition of the Board at least annually and recommends to the full Board nominees for election. The Governance Committee identifies the skills and experience needed to replace any departing director and may perform research, either itself or by engaging third parties to do so on its behalf, to identify and evaluate director candidates.

     Finance Committee: The Finance Committee’s purpose is to assist the Board in carrying out its oversight responsibilities relating to financial matters affecting Omnicom, including in respect of acquisitions, divestitures and financings and the oversight of risk as described in “Risk Oversight” below.

     The members of our Finance Committee are Messrs. Crawford (Committee Chair), Batkin, Murphy, Purcell and Roubos.

     The Finance Committee met 10 times last year.

     Executive Committee: The Executive Committee’s purpose is to act on behalf of the Board in the management of the Board’s business and affairs between Board meetings, except as specifically prohibited by applicable law or regulation, or by our charter or By-laws.

     The members of our Executive Committee are Messrs. Coleman (Committee Chair), Crawford, Murphy, Purcell and Roubos.

     The Executive Committee met four times last year.

     Qualified Legal Compliance Committee: Our Qualified Legal Compliance Committee (“QLCC”) is comprised of the current members of our Audit Committee. As contemplated by SEC rules on corporate governance, the purpose of the QLCC is to receive, investigate and recommend responses to reports made by attorneys employed or retained by Omnicom or one of its subsidiaries of evidence of any material violation of U.S. federal or state securities law, material breach of fiduciary duty arising under U.S. federal or state law or a similar material violation of any U.S. federal or state law. The QLCC only meets when necessary and did not meet in 2011.

Each of our directors attended more than 90% of the meetings of the Board and the Committees of the Board on which they served during 2011. We encourage our directors to attend our annual meetings of shareholders, and all of our directors attended the 2011 Annual Meeting of Shareholders.

Qualifications of the Members of the Board of Directors

     In accordance with the process for the selection and nomination of directors described above, the Governance Committee reviews the composition of the Board at least annually and recommends to the full Board nominees for election. As part of its evaluation, the Governance Committee considers the slate of directors as a whole as well as the specific skills, backgrounds, experiences and qualifications of each nominee. The Board believes that a combination of skill-sets and experiences in a variety of industries provides the Board with the necessary range and depth of knowledge to most effectively oversee a company as large and complex as Omnicom. In addition to each nominee’s business experience and service on the boards of other companies, the Board takes into consideration other factors such as the educational background of each director nominee. The below does not include personal traits such as integrity and time commitment that are essential to a nominee’s qualifications and is not intended to be an exhaustive description of the qualifications that the Board considered with respect to the director nominees.

• John D. Wren: Through the positions Mr. Wren has held at Omnicom and its networks, including that of President and Chief Executive Officer of Omnicom since January 1997, Mr. Wren possesses an in-depth understanding of the Company’s complex global businesses and strategy. As the former Chief Executive Officer of Omnicom’s Diversified Agency Services division, Mr. Wren has tremendous advertising, marketing and corporate communications experience. Under his leadership, Diversified Agency Services grew to become Omnicom’s largest operating group. Together with his strategic vision, Mr. Wren’s vast knowledge of Omnicom, its businesses and its clients enables him to provide important insights to the Board. Mr. Wren is also a member of the International Business Council of the World Economic Forum, and as such, he has direct exposure to the dynamic issues facing a myriad of international companies. This exposure is a valuable asset to the Company and enhances the Board’s ability to judiciously oversee management of Omnicom’s own complex global businesses.
• Bruce Crawford: Mr. Crawford brings to the Board an unmatched tenure and degree of experience in the advertising, marketing and corporate communications industries. His involvement in the industry began in 1956, and since then he has held a diverse array of positions, such as Omnicom’s Chairman of the Board, President, and Chief Executive Officer. In addition, Mr. Crawford has held a variety of high-level positions at BBDO and for several years was the President and Chief Executive Officer of BBDO. These positions have earned Mr. Crawford an extremely keen understanding and a vast scope of knowledge of Omnicom’s business operations and strategy. Mr. Crawford’s experiences and qualifications also include his active involvement on a number of non-profit boards.
• Alan R. Batkin: The selection of Mr. Batkin as a director nominee was partly grounded in the fact that his 16 years of experience as the Vice Chairman of a geopolitical consulting firm advising multinational companies brings to the Board a genuine comprehension and knowledge of the strategy and management of a dynamic and global business. Mr. Batkin understands the complex relationships crucial to successfully running international businesses, as well as the sophisticated strategies involved in expanding international business operations. Growing Omnicom’s non-U.S. operations is critical to our long-term business strategy and Mr. Batkin’s expertise in this regard is a critical component of the Board’s mix of skill sets. Having worked for more than 22 years in senior investment banking and accounting positions, Mr. Batkin also has high-level financial experience and can provide the Board with valuable input relating to matters of corporate finance and asset management. This experience is additive not only to his role as a director, but also to his service as a member of our Finance Committee. In addition, Mr. Batkin has extensive experience serving on the boards and audit committees of several public companies in a variety of industries.
• Mary C. Choksi: With her extensive investment management experience, Ms. Choksi brings to the Board a sophisticated comprehension of the financial matters inherent to running a global business enterprise. It is central to Omnicom’s growth and successful financial performance that the Board of Directors’ knowledge-base includes Ms. Choksi’s understanding of the utilization of assets to generate growth. Ms. Choksi is a founding partner and Managing Director of the investment management enterprise Strategic Investment Group and a founder and, until recently Managing

6

Director, of Emerging Markets Management, which manages portfolios of emerging markets securities. As such, Ms. Choksi has the highest level of experience managing assets, evaluating investment risk, developing investment strategies and determining the optimal use of corporate assets. In addition, Ms. Choksi’s career includes 10 years of experience at the World Bank, primarily working in the Bank’s development arm focusing on projects in South and Southeast Asia. Through this role, Ms. Choksi acquired a keen appreciation of the many challenges facing a multinational company as it navigates foreign markets and hones its global investment strategies. Collectively, this experience and learning is an extremely valuable component of the overall mix of skills necessary for the Board to effectively oversee the development of Omnicom’s diversified global businesses. Ms. Choksi also has considerable experience as a member of the board and audit committees of other public companies.


• Robert Charles Clark: Among other things, Mr. Clark provides the Board with corporate governance expertise and substantial knowledge of corporate law, including experience gained as a Harvard University Distinguished Service Professor, Harvard Law School, and a tenured professor of law at Yale Law School. In these positions Mr. Clark has become one of the foremost authorities on corporate governance matters and has developed an acute appreciation for the intricacies of corporate law and a tremendous knowledge of corporate governance best practices. Mr. Clark’s corporate governance and compliance expertise is particularly beneficial to his service as a member of Omnicom’s Governance and Audit Committees. In addition, Mr. Clark has valuable accounting experience through the position he has held as dean of a leading law school responsible for all aspects of its management, including financial. Mr. Clark also has extensive public and private company board experience and serves as a member of the Audit Committee and Chair of the Nominating & Governance Committee of Time Warner. He also serves as Chair of the Nominating and Governance Committee and a member of the Human Resources, Corporate Governance and Social Responsibility, and Executive Committees of Teachers Insurance and Annuity Association (TIAA). Through his service on the boards of both corporate institutions such as Time Warner and financial institutions such as TIAA, as well as the boards of other large public companies, Mr. Clark possesses an in-depth knowledge of the financial management and business operations and strategies of a global enterprise.
• Leonard S. Coleman, Jr.: Omnicom and its Board of Directors benefit from the diverse business experience that Mr. Coleman has acquired over his career, including during more than a decade of senior management experience in Major League Baseball where he took on a wide range of executive management responsibilities. Mr. Coleman gained significant financial experience through his years of working as a municipal finance banker at Kidder Peabody. Further, he has extensive government experience having served as Commissioner of the New Jersey Department of Community Affairs where his responsibilities included overseeing all local and county budgets. As Commissioner of New Jersey’s Department of Energy, he developed energy policy for the state. In addition, Mr. Coleman was Chairman of the Hackensack Meadowlands Development Commission developing zoning regulations for the area, Chairman of the New Jersey Housing and Mortgage Finance Agency, Vice Chairman of the State Commission on Ethical Standards, a member of the Economic Development Authority, Urban Enterprise Zone Authority, Urban Development Authority, State Planning Commission and New Jersey Public Television Commission, and President of the Greater Newark Urban Coalition. Mr. Coleman also lived overseas for several years serving as a management consultant. Mr. Coleman’s experiences and qualifications also include active involvement on the boards of a number of large public companies, providing him with a deep understanding of the operational and financial aspects of businesses, both domestic and international.
• Errol M. Cook: Mr. Cook provides the Board with, among other things, valuable accounting experience and financial expertise that directly relates to Omnicom’s businesses, including through the high-level positions he has held at the international accounting firm Ernst & Young. He served as Chairman of the Media and Entertainment Committee and Chairman of the Retail Industry Committee of the New York State Society of CPAs. While at Warburg Pincus, a global leader in the private equity industry, Mr. Cook served on the FASB task force on business combinations and goodwill accounting and later consulted for companies preparing for Sarbanes-Oxley. Through such

7

work experience, Mr. Cook has developed an expert understanding of corporate compliance issues and best practices, which is a valuable contribution to his service as a member of Omnicom’s Audit and Governance Committees. All of these positions have provided Mr. Cook with a strong accounting and financial background, including a comprehensive understanding of accounting rules and practices, financial statements, corporate finance, capital markets and asset management, each specifically in the context of Omnicom’s businesses. Mr. Cook also has experience as a former member of the board and audit committees of other public companies.


• Susan S. Denison: With her many years of experience in media and marketing, including multiple senior management roles for companies as varied as Richardson-Vicks, Clairol, Showtime Networks, Revlon and Madison Square Garden, Ms. Denison provides Omnicom and its Board with a deep understanding of consumer behavior and a strategic vision of the business operations of Omnicom’s agencies. As Partner of an executive search firm and an executive within the media, entertainment and consumer products industries, Ms. Denison brings to the Board an intimate familiarity with executive compensation practices, as well as an extensive knowledge of complex media strategies, the oversight of management, and consumer market insights. Ms. Denison’s leadership experience as a Partner at Cook Associates where she is involved in executive recruiting of the most senior executives, generally at the “C Suite” level, provides her with unparalleled knowledge of the compensation policies and practices of large public companies. This knowledge is an extremely valuable contribution to her role as a member of Omnicom’s Compensation Committee and better enables the Board to perform its function of overseeing management retention and succession. Ms. Denison also brings an international perspective to the Board through her prior service on the Board and Compensation Committee of a company listed on the Tel-Aviv Stock Exchange.
• Michael A. Henning: The selection of Mr. Henning as a director nominee was based, among other things, upon his extensive experience gained over a career spanning 40 years in senior positions for Ernst & Young, an internationally recognized accounting firm. At Ernst & Young, Mr. Henning served in a variety of positions including that of Deputy Chairman, Chief Executive Officer International, and Vice Chairman of Taxation. One of the many areas in which Mr. Henning’s long and distinguished career has made him knowledgeable is taxation, both domestic and international. His highly developed understanding of complex domestic and worldwide taxation regulations, policies and practices is an important component of the Board’s aggregation of skill-sets. Mr. Henning’s in-depth understanding of financial and accounting matters and his perceptive insights into the issues facing a multinational business such as Omnicom are extremely helpful to the Board and its Audit Committee. Further, Mr. Henning has served on the board, audit committees and compensation committees of several large public companies.
• John R. Murphy: Mr. Murphy has significant experience in the newspaper publishing industry in which he has served in the roles of president, publisher and editor. In such varied roles, his supervisory purview has included the advertising and circulation departments, allowing him to bring to the Board a keen knowledge of the media buying perspective which is a crucial component of Omnicom’s businesses. In addition, Mr. Murphy’s service as Vice Chairman of National Geographic Society for over 13 years provides him with valuable business, leadership and management experience and allows him to provide the Board with insight into strategic business development and operational matters. Mr. Murphy also has considerable financial knowledge and expertise based in part on his mutual fund and hedge fund experience as the Chairman of PNC Funds. Through his service on the boards of other companies in a wide variety of industries and, in particular, through his long tenure as the chairman of the audit committees of three public companies, including Omnicom, Mr. Murphy has a sizeable amount of board and audit committee experience which is a significant asset to Omnicom’s Board and greatly enhances his position as the Chairman of its Audit Committee.
• John R. Purcell: Among his other qualifications, Mr. Purcell’s years of experience as a tax lawyer at Covington & Burlington and as internal tax counsel at United Technologies have endowed him with a keen insight into legal issues and corporate compliance matters. The strength of judgment derived from this honed insight is a crucial aspect of what qualifies him to serve as the Chairman of Omnicom’s Governance Committee. Further, his extensive experience as a tax lawyer also provides

8

him with a true understanding of the important taxation issues implicated in Omnicom’s global business operations. In addition, Mr. Purcell has many years of senior management experience working in the publishing, broadcasting and marketing industries in roles as varied as Chief Executive Officer, Chief Financial Officer and Chief Operating Officer which gives him a solid grasp of how to effectively oversee the management of a complex advertising, marketing and corporate communications company and, coupled with his distinguished career in banking and finance, how to deploy a global corporation’s assets and optimize its capital structure. As a member of Omnicom’s Board of Directors since its creation in 1986, Mr. Purcell has a deep understanding of Omnicom’s history, strategies, operations, businesses and customers. This accumulated knowledge is an asset to the Board and is extremely valuable to Omnicom in the development of its complex global businesses. Mr. Purcell’s contribution to Omnicom’s Board is further enhanced by his extremely significant board experience at approximately 15 other public companies.


• Linda Johnson Rice: As a director, Mrs. Johnson Rice provides Omnicom with a unique perspective into expanding the operations and building the businesses of a global corporate enterprise, in part developed through her leadership role as Chairman of a multi-media company. The knowledge-base Mrs. Johnson Rice has developed through her experience in this role is a valuable part of the Board’s overall mix of business expertise, particularly in light of the importance of growth to Omnicom’s commitment to increasing shareholder value. In addition, Mrs. Johnson Rice’s acute understanding of advertising and brand management and substantial knowledge of consumer businesses developed during her tenure as a Vice President and later as President and Chief Operating Officer and Chief Executive Officer of Johnson Publishing Company brings to the Board valuable insight into Omnicom’s businesses and the concerns of its clients, a matter of paramount importance to Omnicom’s global business strategy. Mrs. Johnson Rice also has very broad experience through having served for more than 20 years on the boards, audit committees, compensation committees and nominating and governance committees of several other large public companies in a variety of industries.
• Gary L. Roubos: Mr. Roubos has been chosen as a director nominee partly because of his extensive experience in business operations and executive leadership gained from the many years he dedicated to leading a world-wide, diversified industrial manufacturing corporation. As the Chairman and Chief Executive Officer of Dover Corporation, Mr. Roubos developed a broad strategic vision and became expertly knowledgeable about the business operations of a global business enterprise. This vision and knowledge play an important role in the Board’s oversight of Omnicom and its management. Prior to leading Dover Corporation, Mr. Roubos held a variety of manufacturing positions, including plant management and sales, through which he developed a deep understanding of the various components comprising a business enterprise. This knowledge base proved essential to his remarkably successful track record at Dover Corporation and, together with his high-level management experience as the Chairman of Dover Corporation, makes Mr. Roubos’s contribution to Omnicom’s Board extremely valuable. This contribution is further enhanced by the fact that Mr. Roubos has also actively served on public company boards, audit committees, compensation committees and nominating and governance committees.

Risk Oversight

     Our Board oversees an enterprise-wide approach to risk management, designed to support the achievement of organizational objectives, including strategic objectives, to improve long-term organizational performance and enhance shareholder value. The principal oversight function of the Board and its Committees includes understanding the material risks the Company confronts and methods to mitigate or manage those risks. The Board focuses on the Company’s general risk management strategy and the most significant risks facing the Company. Management is responsible for establishing our business strategy, identifying and assessing the related risks and establishing appropriate risk management practices. Our Board reviews our business strategy and management’s assessment of the related risk, and discusses with management the appropriate level of risk for the Company.

9

     Our Board administers its risk oversight function with respect to our operating risk as a whole, and the Board and its Committees meet with management at least quarterly to receive updates with respect to our business operations and strategies, financial results and the monitoring of related risks. The Board also delegates oversight to the Audit, Governance, Compensation and Finance Committees to oversee selected elements of risk:

• Our Audit Committee oversees financial risk exposures, including monitoring the integrity of the financial statements, internal control over financial reporting, and the independence of the independent auditors of the Company. The Audit Committee inquires of management and the accountants about significant risks or exposures and assesses steps management is taking in light of any such risks and discusses guidelines and policies governing the process by which management of the Company assesses and manages the Company’s exposure to risk. The Audit Committee receives an assessment report from the Company’s internal auditors on at least an annual basis and more frequently as appropriate. The Audit Committee also assists the Board in fulfilling its oversight responsibility with respect to compliance with legal and regulatory matters related to the Company’s financial statements and meets quarterly with our financial management, independent auditors and legal advisors for updates on risks related to our financial reporting function.
• Our Governance Committee oversees governance-related risks by working with management to establish corporate governance guidelines applicable to the Company, including recommendations regarding director nominees, the determination of director independence, Board leadership structure and membership on Board Committees. The Company’s Governance Committee also oversees risk by working with management to adopt codes of conduct and business ethics designed to encourage the highest standards of business ethics.
• Our Compensation Committee oversees risk management by participating in the creation of compensation structures that create incentives that encourage a level of risk-taking behavior consistent with the Company’s business strategy.
• Our Finance Committee oversees financial, credit and liquidity risk by overseeing our Treasury function to evaluate elements of financial and credit risk and advise on our financial strategy, capital structure, capital allocation and long-term liquidity needs, and the implementation of risk mitigating strategies.

     The Company’s management is responsible for day-to-day risk management. The CEO, CFO and General Counsel periodically report on the Company’s risk management policies and practices to relevant Board Committees and to the full Board. Our Treasury, Legal, Controller and Internal Audit functions work with management at the agency level, serving as the primary monitoring and testing function for company-wide policies and procedures, and managing the day-to-day oversight of risk management strategy for the ongoing business of the Company. We believe the division of risk management responsibilities described above is an effective approach for addressing the risks facing the Company and that our Board leadership structure supports our approach.

Risk Assessment in Compensation Programs

     We have assessed the Company’s compensation programs and have concluded that our compensation policies and practices do not create risks that are reasonably likely to have a material adverse effect on the Company. Frederic W. Cook & Co., an independent third-party compensation consultant, assisted Omnicom management in 2011 in reviewing our executive and broad-based compensation and benefits programs on a worldwide basis to determine if the programs’ provisions and operations are likely to create undesired or unintentional risk of a material nature. This risk assessment process included a review of program policies and practices; analysis to identify risk and risk control related to the programs; and determinations as to the sufficiency of risk identification, and the balance of potential risk to potential reward. Although we reviewed all compensation programs, we focused on the programs with variability of payout, with the ability of a participant to directly affect payout and the controls on participant action and payout.

     Based on the foregoing and the fact that we believe no subsequent change in the Company’s compensation programs creates risks reasonably likely to have a material adverse effect on the Company, we believe that our compensation policies and practices do not create inappropriate or unintended significant risk to the Company

10

as a whole. We also believe that our incentive compensation arrangements provide incentives that do not encourage risk-taking beyond the organization’s ability to effectively identify and manage significant risks; are compatible with effective internal controls and our risk management practices; and are supported by the oversight and administration of the Compensation Committee with regard to executive compensation programs.

Ethical Business Conduct

     We have a Code of Conduct designed to assure that our business is carried out in an honest and ethical way. The Code of Conduct applies to all of our, and our majority-owned subsidiaries’, directors, officers and employees and requires that they avoid conflicts of interest, comply with all laws and other legal requirements and otherwise act with integrity. In addition, we have adopted a Code of Ethics for Senior Financial Officers regarding ethical action and integrity relating to financial matters applicable to our senior financial officers. Our Code of Conduct and Code of Ethics for Senior Financial Officers are available on our website at http://www.omnicomgroup.com, and are also available in print to any shareholder that requests them. We will disclose any future amendments to, or waivers from, certain provisions of these ethical policies and standards for senior financial officers, executive officers and directors on our website within the time period required by the SEC and the NYSE.

     We also have procedures to receive, retain and treat complaints regarding accounting, internal accounting controls or auditing matters and to allow for the confidential and anonymous submission by employees of concerns regarding questionable accounting or auditing matters, as well as possible violations of our Code of Conduct or Code of Ethics for Senior Financial Officers. The procedures are posted on our website at http://www.omnicomgroup.com and the websites of our various global networks.

Shareholder Communications with Board Members

     Interested parties, including shareholders, may communicate (if they wish on a confidential, anonymous basis) with the outside directors, the Chairs of our Audit, Compensation, Finance, Governance and Executive Committees or any individual director (including the presiding director of the executive sessions of our independent non-management directors) on board-related issues by writing to such director, the Committee Chair or to the outside directors as a group c/o Corporate Secretary at Omnicom Group Inc., 437 Madison Avenue, New York, New York 10022. The envelope should clearly indicate the person or persons to whom the Corporate Secretary should forward the communication. Communications will be distributed to the Board, or to any individual director or directors as appropriate, depending on the facts and circumstances outlined in the communications.

EXECUTIVE COMPENSATION

COMPENSATION DISCUSSION AND ANALYSIS

Overall Compensation Objectives and Principles

     The Compensation Committee is responsible for establishing, implementing and monitoring Omnicom’s executive compensation policies and program. The overarching goal of our compensation program is to:

• attract, motivate and retain the talented executives who are a critical component of Omnicom’s long-term success by providing each with a competitive total rewards package; and
• ensure that executive compensation is aligned with both the short and long-term interests of shareholders.

     We accomplish this by closely tying pay to performance, maintaining a high degree of variable compensation and maintaining competitive compensation levels.

Fiscal Year 2011 Performance

     During fiscal year 2011, the global economy continued to face uncertainty, including the euro zone’s instability, which affected the United States and other markets around the world. Regulatory uncertainty continued to impact corporate investment and the availability of capital. Despite these unsettled conditions on our business, Omnicom’s leadership generated very strong results throughout 2011, positioned our business extremely well for future growth and created significant value for our shareholders. The following highlight key achievements:

Omnicom continued to achieve operational excellence and deliver solid financial growth.

     Annual revenue growth was 10.6%, the highest since 2007. Additionally, annual revenue of $13.87 billion was the highest in the Company’s history. A number of cost initiatives were taken this year, including 35 dispositions of non-strategic businesses. Our strong revenue performance, combined with our continuing emphasis on cost control, resulted in EBITA growth of 15.1%. The strategic review of our portfolio of agencies, together with other steps we took during 2011 to improve our operations, resulted in significant progress towards our margin goal during the year. Our EBITA margin increased 50 basis points to 12.7%. (EBITA is a non-GAAP financial measure that represents earnings before interest, taxes and amortization of intangible assets. EBITA margin is a non-GAAP financial measure that represents EBITA divided by revenue. A reconciliation of EBITA and EBITA margin to the U.S. GAAP financial measure of Operating Income is provided on page 14 of our 2011 Annual Report on Form 10-K.)

     For the year, all of our industry groups had positive growth and in aggregate Omnicom led the industry with 6.1% organic growth. This was driven by a combination of factors: very strong new business wins, a rebound in spending by many clients, continued double-digit growth in developing markets and, most importantly, our agencies continuing to expand their capabilities and service offerings, utilizing the many new technologies and communication mediums that are being developed in the marketplace. Full year net income increased over 15% and EPS increased over 23%.

     We continued to see strong client retention rates, expansion of existing relationships and meaningful new business wins. We continued to successfully build our business through a combination of prudently priced acquisitions and well-focused internal development. As a result, both return on invested capital and return on equity continued to improve, reaching an industry-leading18.8% and 26.9%, respectively. Our balance sheet remains extremely strong, providing us the flexibility to pursue attractive investments as they arise.

We accelerated our investments in digital, social, mobile and analytics across the networks.

     Omnicom continued to pursue a multi-pronged strategy built around the core idea that all of our agencies must have strong digital capabilities to compete in the future. As a result, Omnicom leadership helped in pushing our agencies, where needed, to continue to accelerate the expansion of their digital capabilities. We believe our financial strength and our open-source approach to technology give us the flexibility to succeed in adapting faster to change by owning only those capabilities that allow us to add the greatest value for our clients while limiting the need to protect outdated services and platforms.

12

We acquired new capabilities to complement our existing skill sets and entered into key strategic partnerships.

     Omnicom made investments that helped us to deliver innovative and integrated solutions for our clients and to expand our business into new areas. One example of this integration is the Bringing Happiness Home campaign Omnicom accomplished for PepsiCo in China for the Chinese New Year. The campaign features three of PepsiCo’s strongest brands – Pepsi, Lay’s and Tropicana – and was delivered on TV, online, in the store and at home. The results have been outstanding.

     In 2011 Omnicom and Microsoft Corp. announced plans to establish a global creative exchange – a first of its kind for both Omnicom and Microsoft – in which Microsoft will provide technology ambassadors to Omnicom’s agencies to help them simplify the process of developing advertising content that can be utilized across multiple screens. In addition, Omnicom and AOL Inc. formed a partnership to infuse digital technology into the beginning of the creative process and enrich creative executions through a more cohesive use of technology in campaigns. Omnicom also partnered with many new media companies in 2011, including Facebook, Adobe and Yahoo.

We continued to strengthen our footprint geographically and expand our presence in key emerging markets.

     Over the past few years, the percentage of our business generated from markets other than the U.S., U.K. and euro currency markets has grown significantly and now represents over 22% of our business compared to 16.6% in 2009. Our investments in digital and in developing markets helped us deepen and extend our key client relationships.

     Omnicom completed and announced a number of acquisitions designed to help build our footprint geographically and to add important skill sets where appropriate. Key among these transactions was our acquisition of the controlling stake in India’s Mudra Group, which closed in late October. Mudra Group is one of India’s leading integrated marketing communications companies. This acquisition will significantly expand Omnicom’s service capabilities and presence in Asia’s third largest economy. We also completed important transactions in Turkey and South Africa. In addition, we completed the acquisition of a control position in the Clemenger Group (the leading communications group in Australia and New Zealand) in the first quarter. This acquisition will accelerate Omnicom’s expansion in Asia through leveraging the Clemenger Group’s broad portfolio of marketing companies and talent pool in the region.

Omnicom agencies were recognized around the world for their work in 2011.

• BBDO and DDB finished number one and number two in the Gunn Report’s 2011 Most Awarded Agency Networks in the World. BBDO was named 2011 Global Agency of the Year by both Adweek and Campaign magazines, and for the fifth year in a row, BBDO topped The Big Won.
• OMG was named Global Media Agency of the Year by Adweek and Media Agency of the Year by Ad Age. TBWA\HAKUHODO was named 2011 International Agency of the Year by Ad Age. Ketchum was awarded the International Consultancy of the Year honor by PR Week, and LatinWorks was named Ad Agency Multicultural Agency of the Year.
• Omnicom agencies dominated the spotlight at the Digital Media Awards in Beijing, sweeping 11 out of 16 Golds, the Platinum award and the Digital Agency of the Year title.
• Omnicom agencies BBDO and DDB ranked among the top three networks recognized at the 58th international Festival of Creativity in Cannes for the scope of their creative work.

As a result of our strong financial position, we returned a significant amount of capital to our stockholders, both through our increased regular quarterly dividend and our stock repurchase program.

     For the eighth consecutive year, we generated over $1 billion in free cash flow and, together with share buybacks and dividends, we returned over $1 billion to shareholders in 2011. We also increased our dividend by 20%. Since 2009, Omnicom’s dividend per share has doubled.

Compensation Decisions Reflected Our Performance

     The achievements discussed above were a direct result of the leadership of our named executive officers and other senior executives and provide significant context for the Compensation Committee’s pay-for-performance approach and the key 2011 compensation decisions. Our named executive officers, or “NEOs”, for fiscal year 2011 were:

• John D. Wren, Omnicom President and Chief Executive Officer
• Randall J. Weisenburger, Omnicom Executive Vice President and Chief Financial Officer
• Philip J. Angelastro, Omnicom Senior Vice President Finance and Controller
• Dennis Hewitt, Omnicom Treasurer
• Michael J. O’Brien, Omnicom Senior Vice President, General Counsel and Secretary

     After conducting a comprehensive review of our executive compensation program, the Compensation Committee made important changes to the process by which incentive compensation awards were determined for performance in fiscal 2011. This new process further aligns with our pay-for-performance objectives. The incentive award that each named executive officer received was derived from a pre-set formula incorporating a combination of the following quantitative and qualitative performance metrics:

• Omnicom’s annual financial performance against annual performance targets established by the Compensation Committee;
• Omnicom’s annual financial performance against that of an industry peer group established by the Compensation Committee; and
• Individual performance evaluated by looking at how an NEO’s personal performance contributed to advancing Omnicom’s business objectives.

     The Compensation Committee also paid a portion of Messrs. Wren, Weisenburger, O’Brien and Hewitt’s incentive compensation award in performance restricted stock units (PRSUs), for which the ultimate number of shares awarded varies based on Omnicom’s future performance as compared to that of an industry peer group. The Compensation Committee believes that the use of PRSUs with the vesting provisions described below in the section entitled “Fiscal Year 2011 Compensation” focuses the executive on the Company’s long-term performance without leading to imprudent risk-taking.

     Omnicom strives to closely link executive compensation to performance by making a significant portion of potential annual compensation variable and performance driven. The more senior an executive becomes, the lower his base pay will be as a proportion of his entire compensation package and the higher his incentive-based and retention components will be as a proportion of his entire compensation package. We believe this is aligned with shareholder interest and the long-term interests of the Company. For each NEO, the majority of his total compensation was variable and based on performance. With respect to our CEO, over 92% of his total compensation was variable and based on performance.

     The Committee believes that our executive compensation program aligns with performance, reflects our business philosophy and reflects competitive practices regarding executive compensation. At our 2011 Annual Meeting of Shareholders, the Company held its first annual advisory vote on executive compensation (a “say-on-pay proposal”). A substantial majority of the votes cast on the say-on-pay proposal at that meeting were voted in favor of our 2010 compensation. The Compensation Committee believes this affirms shareholders’ support of the Company’s approach to executive compensation. Omnicom’s strong performance in fiscal year 2011 reinforces the Committee’s view that our executive compensation program is achieving its objectives, and the Committee made no significant changes to the program during the year in response to last year’s say on pay vote. The Compensation Committee will continue to consider the outcome of the Company’s say-on-pay votes when making future compensation decisions for the named executive officers.

14

Elements of Omnicom Compensation

     Our principal components of pay are a base salary, an annual performance-based cash award, an annual performance-based equity award, and, periodically, a long-term equity award vesting over a five-year period. Each of these components and the manner in which decisions for 2011 were made for each NEO are more fully discussed in the sections that follow.

Base Salary

     The objective of base salary is to provide a portion of compensation to the named executive officer that is not “at risk” like incentive bonuses or equity awards, and is generally unaffected by fluctuations in company performance or the market in general. The base salaries for the named executive officers are determined by the Compensation Committee and, in the case of the President and Chief Executive Officer, approved by the full Board.

     Adjustments in base salary for named executive officers are discretionary and are generally considered no more frequently than every 24 months. Messrs. Wren, Weisenburger and O’Brien have not had an increase in base salary in nine years. Mr. Angelastro has not had an increase in base salary in seven years. Omnicom determines base salary adjustments based upon the report of our compensation consultant, the general knowledge of our CEO and Compensation Committee of base salaries paid to similarly positioned executives, salaries paid historically, tax and accounting issues and, when appropriate, personal performance as assessed by the Committee and the Chief Executive Officer. No formulaic base salary adjustments are provided to the named executive officers.

Annual Performance-Based Compensation Awards

     A key component of our executive compensation program is an annual performance-based bonus awarded pursuant to Omnicom’s Senior Management Incentive Plan (the “Incentive Bonus Plan”). Under the Incentive Bonus Plan, eligible executive officers may, subject to Compensation Committee oversight and discretion (or in the case of the President and Chief Executive Officer, subject to Board input and ratification), receive annual performance-based bonuses. It is Omnicom’s philosophy that its named executive officers should be rewarded based upon Omnicom’s financial performance as well as each executive’s contribution to advancing Omnicom’s business strategy and our long term performance.

     For performance in fiscal year 2011, the Compensation Committee established a maximum incentive compensation level and a target incentive compensation level set at a percentage of the maximum incentive compensation level, which are shown below in the “Grant of Plan-Based Awards in 2011” table. As described below, the Compensation Committee consults with its compensation consultant to determine the range of total compensation for similarly positioned executives at companies of comparable size and profitability. The Compensation Committee takes the information provided in the compensation consultant report into consideration when determining the bonus range for our named executive officers.

     As described in greater detail below, in exercising its discretion under the Incentive Bonus Plan, the Compensation Committee considered the following combination of quantitative and qualitative performance measures:

• 30% based on Omnicom financial performance as compared to annual company targets (“Performance Award”);
• 20% based on Omnicom financial performance compared to an industry peer group (“Peer Award”); and
• 50% based on individual performance (“Qualitative Award”).

     We believe our goals are meaningful and challenging, the achievement of which is designed to drive stockholder value.

15

I. Omnicom 2011 Performance Award (30% of Target Incentive Award)

     The Compensation Committee considered the following performance measures regarding Omnicom’s 2011 financial performance measured against financial performance targets established by the Committee, with each measure weighted as indicated:

• 2011 return on equity (ROE) (33¹/3%)
• 2011 earnings before interest, taxes and amortization (EBITA) margin (33¹/3%)
• 2011 organic growth (33¹/3%)

     Organic growth is total revenue growth less the change in revenue attributable to foreign exchange rates and businesses acquired net of businesses that were disposed. A predetermined multiplier of between 0 and 2.0 (the “Performance Multiplier”) was ascribed based on the range of Omnicom performance with respect to each performance measure. The performance multipliers ranged from zero to 2.0 times for: (a) ROE performance of less than 19.0% to greater than 23.0%; (b) EBITA margin performance of less than 12.0% to greater than 13.0%; and (c) organic growth of less than 3.0% to greater than 7.0%, respectively. The Performance Multiplier was applied to each metric’s weighting within the category based on the results achieved to arrive at a weighted score for the performance award (the “Performance Weighted Score”). A description of the calculation of this portion of the incentive award is provided below under the section entitled “Fiscal Year 2011 Compensation Decisions”.

II. Omnicom 2011 Peer Award (20% of Target Incentive Award)

     The Compensation Committee considered the following performance measures regarding Omnicom’s 2011 financial performance as compared to that of an industry peer group, which includes WPP plc, Publicis Groupe SA, Interpublic Group of Companies and Havas, with each measure weighted as indicated:

• 2011 ROE (40%)
• 2011 EBIT margin (20%)
• 2011 organic growth (20%)
• 2011 organic growth plus EBIT margin (20%)

     A predetermined multiplier of between 0 and 2.0 (the “Peer Multiplier”) was ascribed based on the range of performance with respect to each performance measure. The Peer Multiplier is based on Omnicom’s percentile rank when comparing its performance to the performance of the peer group. For each performance measure the Peer Multiplier ranged from zero if Omnicom’s performance ranked less than 25% of the peer group’s performance (the “peer performance”), to 2.0 times if Omnicom’s performance ranked equal to 100% of the peer performance. The Peer Multiplier was applied to each metric’s weighting within the category based on the results achieved to arrive at a weighted score for the peer award (the “Peer Weighted Score”). A description of the calculation of this portion of the incentive award is provided below under the section entitled “Fiscal Year 2011 Compensation Decisions”. Aegis Group was originally included in the industry peer group, but during the third quarter of 2011 it executed a large disposition that substantially and materially altered its business and the reporting of its financial results. As a result, the Compensation Committee exercised its discretion to exclude Aegis from the industry peer group.

III. Qualitative Award (50% of Target Incentive Award)

     To assess 2011 individual performance, the Compensation Committee, with the assistance of Omnicom’s President and Chief Executive Officer, looked to determine how each named executive officer contributed to advancing the core “pillars” that serve as the foundation of our business strategy: providing best in class services to clients, maximizing efficiencies and minimizing risk through enterprise-wide initiatives and achieving the highest levels of corporate values and integrity.

16

(1) Best in Class Client Services. We achieve this goal by securing the finest available talent in the right disciplines, and deploying that talent in the right places across the globe. The Compensation Committee looks to the role a named executive officer has played in developing our personnel and our client and discipline base. With respect to each, the Compensation Committee reviews an executive’s role, as applicable, in:

• Personnel development

• Providing management development and succession planning

• Recruiting and retaining key and diverse talent

• Training and educating personnel

• Client development

• Retaining clients/business

• Expanding the depth and breadth of our core clients

• Developing new client relationships

• Services development

• Developing the quality and breadth of our key services

• Expanding our global presence in the right places

• Planning acquisitions and divestitures

• Receiving honors and awards for creative excellence and customer service

(2) Enterprise-wide initiatives to maximize efficiencies and minimize risk. Next, our finance and operations team strives to maximize efficiencies and minimize risk through enterprise-wide initiatives that create a high return on invested capital. The Compensation Committee reviews each executive’s involvement in key business management issues such as cash management, business planning, Enterprise Risk Management (ERM), information technology initiatives/consolidation, developing and streamlining financial reporting operations and working capital management.

(3) Corporate values and integrity. Finally, Omnicom leadership strives to achieve the highest levels of corporate values and integrity. The Compensation Committee considers how each executive contributed to Omnicom’s substantial efforts to maximize diversity and inclusion, to achieve the highest levels of corporate social responsibility, including a commitment to environmental and individual community outreach initiatives, and to maintain a professional work-place environment.

     Although each named executive officer is eligible to receive an award pursuant to the Incentive Bonus Plan if his achievements so merit, the granting of a bonus to any named executive officer is entirely at the discretion of the Compensation Committee. The Compensation Committee may choose not to award a bonus to a named executive officer or to reduce the amount of the bonus that results from the application of the quantitative and qualitative measures described above, in each case in light of all factors deemed relevant by the Committee (otherwise referred to in this discussion as “negative discretion”). In addition, to the extent achievement of the performance criteria described above may be impacted by changes in accounting principles and extraordinary, unusual or infrequently occurring events reported in Omnicom’s public filings, the Compensation Committee exercises its judgment whether to reflect or exclude their impact.

     Long Term Equity Component of Annual Performance-Based Compensation Awards

     The Compensation Committee strives to create incentives for the senior management team not only to remain with Omnicom, but to focus long term as a team. We believe that an equity ownership stake in Omnicom is an important component in linking a named executive officer’s compensation to the performance of Omnicom and the creation of long-term shareholder value. Grants of restricted stock, restricted stock units, performance

17

restricted stock units and stock options serve to align the interests of the shareholders with those of the named executive officers by incentivizing the named executive officers toward the creation and preservation of long-term shareholder value. Finally, our equity award agreements contain restrictive covenants that protect our business in the event of an executive’s departure.

     Messrs. Wren, Weisenburger, O’Brien and Hewitt received part of their annual performance-based compensation award in PRSUs. This equity award is designed to reward individual contributions to the Company’s performance as well as motivate future contributions and decisions aimed at increasing shareholder value. Each PRSU represents the right to receive one share of our common stock upon vesting. The ultimate number of shares received by each NEO will depend upon Omnicom’s return on equity over 2012, 2013 and 2014, as compared to the return on equity of Omnicom’s five principal competitors. The target and maximum values of the PRSUs awarded to each NEO are shown in the Summary Compensation Table on page 26 and the accompanying narrative disclosure. Between 0% and 200% of the target number of PRSUs will ultimately be received by the NEOs, depending on Omnicom’s rank as compared to such competitors and the length of the NEOs service with Omnicom over the performance period.

     The PRSUs are eligible to fully vest on December 31, 2014 and distributions of shares underlying the PRSUs will generally occur in 2015. In the event an NEO terminates prior to December 31, 2014, he will be eligible to receive one-third of the number of PRSUs which he would have received absent termination for each calendar year he is employed after the date of grant and such shares will be distributed in 2015. Vesting of the PRSUs and distribution of shares underlying the PRSUs will be accelerated in the event of death, termination due to disability or a change in control.

     Mr. Angelastro received an award of restricted stock units in December 2011. The Compensation Committee believed the award of restricted stock units was important in retaining Mr. Angelastro and maintaining executive leadership. The amount of Mr. Angelastro’s restricted stock unit award was generally determined based on our CEO and Compensation Committee’s judgment of his current and expected future contribution to Omnicom’s performance. Mr. Angelastro’s restricted stock unit award vests over a period of five years, with 20% vesting each year. The restricted stock units are subject to forfeiture if Mr. Angelstro is terminated for certain reasons before the shares become vested as described in more detail in the section below entitled “Potential Payments Upon Termination of Employment or Change in Control”. In light of his recent restricted stock unit award, the Compensation Committee did not award Mr. Angelastro PRSUs as a part of his annual performance-based compensation award.

     Messrs. Wren and Weisenburger are required to retain a certain amount of Company’s equity/stock as described in “Other Arrangements, Policies and Practices Related to Our Executive Compensation Program —Share Ownership Guidelines.”

Compensation Decision Process

     The Compensation Committee annually reviews and approves the compensation of the named executive officers. To aid the Compensation Committee in making its compensation determinations, the Chief Executive Officer annually reviews the performance of each other named executive officer by evaluating the performance factors described in this Compensation Discussion and Analysis and presents his conclusions and recommendations to the Committee. The Compensation Committee considers the Chief Executive Officer’s recommendations, but ultimately exercises its own discretion. With respect to 2011 compensation, the Compensation Committee did not deviate materially from our Chief Executive Officer’s recommendations.

     Because of the competitive nature of our business, the loss of key executives to competitors is a significant risk and Omnicom’s paramount concern is to attract and retain the highest-caliber executive team to ensure that Omnicom is managed in the most effective possible manner. The Compensation Committee directly retains the services of Frederic W. Cook & Co. (“Cook & Co.”), an independent third-party compensation consulting firm, for input on a range of external market factors, including evolving compensation trends, and market-standard compensation levels and elements. Cook & Co. reports directly and exclusively to the Compensation Committee. Cook & Co. only provides compensation consulting services to the Compensation Committee, and works with Omnicom’s management only on matters for which the Committee is responsible. Moreover, Cook & Co. does not perform any other services for, or receive any other fees from, the Company or any of its subsidiaries other

18

than in connection with its work for the Compensation Committee. Cook & Co. holds no Omnicom stock and the Compensation Committee believes the services Cook & Co. provides for the Company do not raise any conflicts of interest.

     The Compensation Committee consults with Cook & Co. to obtain general observations on the Company’s compensation programs from which the Committee determines the target range of total compensation for each executive. Though Cook & Co. provides general observations on the Company’s compensation programs, it does not determine or recommend specific amounts or forms of compensation for the named executive officers. Although the data provided by Cook & Co. in 2010 influenced the Compensation Committee’s review and analysis, such data did not have a material impact on the Committee’s determination of the levels and elements of our executive compensation in 2011. The peer group the Compensation Committee reviewed in 2010 consisted of companies of comparable size and operational complexity. The group was comprised of the following companies:

Accenture	Computer Sciences Corp.	Time Warner Cable
Automatic Data Processing	DISH Network	Time Warner Inc.
Cablevision	Interpublic Group of Companies	Viacom
CBS	Thomson Reuters	WPP plc

Fiscal Year 2011 Compensation Decisions

     Base Salary

     Based on our Chief Executive Officer and the Compensation Committee’s general knowledge of base salaries paid to similarly positioned executives at companies of comparable size and profitability, and the Compensation Committee’s emphasis on performance-based compensation, the Compensation Committee decided not to adjust the base salaries of any of the named executive officers in 2011.

III. Determination of 2011 Qualitative Award (50%)

     To assess 2011 individual performance, the Compensation Committee, with the assistance of Omnicom’s President and Chief Executive Officer for NEOs other than himself, looked to the following contributions of each named executive officer toward advancing the foundation of our business strategy.

     John D. Wren. Under Mr. Wren’s leadership, Omnicom has grown into one of the world’s largest and most respected marketing communications firms. As part of the original management team that created Omnicom in 1986 and as the Company’s chief executive officer since 1997, he has been the architect of a complex strategy that has positioned Omnicom to serve the global marketing requirements of the world’s most sophisticated marketers. He has championed the creation of unique virtual networks across Omnicom agencies, geographies and disciplines to meet the needs of integrated global clients. He was early to envision the potential of digital technologies, leading the Company’s early investment in and development of digital technologies and capabilities across each of Omnicom’s agencies. He has also been instrumental in leading the Company’s efforts to extend and deepen Omnicom’s capabilities in rapidly growing markets to meet the needs of clients’ global marketing efforts. Throughout this evolution of the Company, Mr. Wren has ensured that Omnicom agencies and networks have continued to build on their strong legacy of creative excellence. Today, Omnicom’s networks and agencies are regarded as the industry’s most creative, as measured by their share of global awards for creative excellence.

     The overarching strategies implemented by Mr. Wren drove strong financial growth during 2011. Mr. Wren’s emphasis on expanding client relationships, as well as his direct leadership role with many of the Company’s largest global clients has resulted in industry-leading organic revenue growth. Such growth, along with Mr. Wren’s focus on improving operating efficiencies, including disposing of non-strategic underperforming agencies and leading the Company’s ongoing shared service center strategies resulted in 14.4% growth in operating income and making significant progress towards achieving our margin improvement goals. He also developed the Company’s acquisition strategy and identified and invested in high-performing businesses, including in rapidly growing markets that will better enable the Company to meet the future marketing requirements of our global clients. Additionally, Mr. Wren has long been instrumental in identifying, attracting, retaining and developing highly-talented key executives, and is deeply committed to disseminating best practices across Omnicom through industry-leading advanced education initiatives such as Omnicom University.

     As a result of Mr. Wren’s leadership, Omnicom both strengthened its balance sheet and returned a significant amount of capital to our stockholders, including more than $1 billion dollars in dividends and share repurchases during 2011. Over the past ten years under Mr. Wren’s leadership, the Company has doubled its revenues and net income while returning 95% of its cumulative net income during that period to Omnicom shareholders in the form of dividends and share repurchases. Since becoming Chief Executive Officer, Mr. Wren has built and led a management team that has averaged greater than 23% return on equity annually.

     Randall J. Weisenburger. Mr. Weisenburger provided key leadership and financial management for our Company. He effectively managed the Company’s capital and liquidity, helped to improve Omnicom’s margins, oversaw the reduction of risk and the strengthening of the Company’s balance sheet. He oversaw the enhancement of the financial planning and analysis process. Mr. Weisenburger, working with Mr. Wren and our senior network management teams identified and invested in high-performing businesses in rapidly growing markets. In addition, he led the ongoing improvements to our working capital management programs, an important effort in maintaining Omnicom’s overall financial performance. Mr. Weisenburger led the efforts to continually develop the skills of our finance and operating personnel and implemented programs for their continuing professional development. He continued to oversee the Company’s efforts in the areas of corporate

20

ethics, enterprise risk management and global corporate social responsibility. In addition, Mr. Weisenburger led the Company’s investor relations efforts.

     Philip Angelastro. Mr. Angelastro continued to play a key leadership role in the financial management of the Company. He effectively managed the Company’s financial reporting function and the preparation of all filings and communications with the Securities and Exchange Commission. He led efforts to define and implement accounting policies and procedures for all Omnicom companies. In addition to overseeing the Company’s financial systems, he plays a key role in our ongoing efforts to improve the efficiency and effectiveness of financial reporting and analysis processes. Mr. Angelastro also managed the Company’s global income tax function, its Sarbanes Oxley compliance activities, as well as its U.S. health and welfare and retirement plans.

     Dennis Hewitt. Mr. Hewitt successfully supported the Chief Financial Officer in developing and maintaining our overall capital structure, which includes public debt offerings, revolving credit facilities, commercial paper program, bank lines of credit and leasing programs. He successfully oversaw (i) global property and casualty insurance programs and related insurance activities; (ii) capital expenditure planning and administration of related leasing activity; (iii) management of global working capital performance including client credit exposures; and (iv) organizing conferences focusing on training and professional development. Mr. Hewitt led his department’s efforts to provide global liquidity with interconnected regional treasury centers that fund operating units, daily requirements and manage foreign exchange exposure and derivatives. He coordinated global corporate social responsibility projects involving financial employees through Omnicom Cares. Mr. Hewitt also played a key role in developing a global information technology program to provide straight-through processing and paperless solutions.

     Michael J. O’Brien. Mr. O’Brien successfully led the Company’s worldwide legal team, managed legal services provided to the Company, and monitored the Company’s compliance with all applicable laws, rules and regulations on a global basis. He played a lead role in setting priorities and agendas for the Company’s Board of Directors and its Committees and provided them with advice on corporate governance developments and best practices, as well as legal risks and requirements. He continued to oversee the implementation of several important corporate governance initiatives. Mr. O’Brien was instrumental to the implementation of initiatives to increase diversity throughout the Company. He played a key role in (i) structuring, implementing and managing compensation and benefits programs, (ii) protecting the company’s intellectual property, (iii) negotiating and ensuring compliance with client contracts, (iv) overseeing legal aspects of the Company’s acquisition and financing activities, and (v) managing the governance of the Company’s many legal entities. In addition, Mr. O’Brien managed the Company’s litigation matters and developed effective litigation strategies.

IV. Compensation Committee Negative Discretion

     While Omnicom experienced strong financial growth during 2011, management continues to place high demands on Omnicom employees. In light of this factor, as well as the excellent performance of our employees and Omnicom’s goal of rewarding such employees, the Compensation Committee and management agreed that it was prudent for the Committee to exercise negative discretion to reduce the amount of management bonuses and to reallocate the funds to the general incentive compensation pool. In addition, due to the restricted stock unit award he received in December, the Compensation Committee reduced the annual incentive award to which Mr. Angelastro was entitled. The amount of the incentive awards paid to the named executive officers for performance in 2011 is set forth in the Summary Compensation Table for 2011 on page 26. The amounts actually awarded can be compared to target and maximum incentive award amounts in the Grants of Plan-Based Awards Table on page 27.

The table below summarizes the calculation of each NEO incentive award for performance in 2011:

Name	Target Incentive Compensation		Performance Weighted Score		Peer Weighted Score		Qualitative Score		Combined Score		Projected Incentive Compensation		Negative Discretion		Total Incentive Compensation
John Wren	$	12,000,000	44.91	%	36.00	%	50.00	%	130.91	%	$	15,709,200	$	1,450,000	$	14,259,200
Randall
Weisenburger	$	8,640,000	44.91	%	36.00	%	50.00	%	130.91	%	$	11,310,624	$	1,450,000	$	9,860,624
Philip Angelastro	$	1,400,000	44.91	%	36.00	%	50.00	%	130.91	%	$	1,832,740	$	900,000	$	932,740
Dennis Hewitt	$	625,000	44.91	%	36.00	%	50.00	%	130.91	%	$	818,188			$	818,188
Michael O’Brien	$	850,000	44.91	%	36.00	%	50.00	%	130.91	%	$	1,112,735			$	1,112,735

     Performance Restricted Stock Unit Award: For Messrs. Wren, Weisenburger, O’Brien and Hewitt, the Compensation Committee paid a portion of the variable year-end incentive award for performance in 2011 in PRSUs. The maximum number of PRSUs that each NEO is eligible to receive under this award is equal to the dollar value of the equity portion of the 2011 incentive award set forth in the Summary Compensation Table below, divided by the closing price of our common stock on the date of grant ($49.13). The target number is equal to 50% of the maximum (the “Target PRSU Award”). The target amount of each NEO’s award is as follows:

Name	Target PRSU Award
John Wren	43,535
Randall Weisenburger	30,106
Dennis Hewitt	5,516
Michael O’Brien	4,056

     In 2015 our average return on equity over calendar years 2012, 2013 and 2014 will be compared to the average return on equity for each of WPP plc, Publicis Groupe SA, Interpublic Group of Companies, Aegis Group and Havas for the same three-year period and Omnicom’s rank amongst its competitors will be determined. The total number of PRSUs to be distributed will be determined by applying the PRSU Multiplier below to the Target PRSU Award:

Omnicom Rank	PRSU Multiplier
1-2	2.00
3	1.33
4	0.67
5-6	0.00

     The Compensation Committee believes return on equity provides a consistent and comprehensive measure to assess Omnicom’s relative performance. The Compensation Committee believes using return on equity as the single performance measure achieves clear and simple peer group comparison, and serves as a comprehensive means to evaluate various financial metrics. In addition, return on equity is a measure directly tied to the return to our common shareholders over time.

     In the event an NEO terminates prior to December 31, 2014, he will receive in 2015 one-third of the number of PRSUs which he would have received absent termination for each calendar year he is employed after the date of grant. Dividend equivalents will be paid in cash on the maximum number of PRSUs to which the executive is entitled at such times as dividends are paid to stockholders of Omnicom. Vesting of the PRSUs and distribution of shares underlying the PRSUs will be accelerated in the event of death, termination due to disability or a change in control. The Compensation Committee believes that these vesting provisions motivate executives to make decisions that focus on the long-term, sustainable growth of our Company, increasing shareholder value as a result.

Other Arrangements, Policies and Practices Related to Our Executive Compensation Program

     Executive Stock Ownership Guidelines. We have adopted Executive Stock Ownership Guidelines that require our President and Chief Executive Officer and Chief Financial Officer to hold shares of Omnicom common stock with a value equal to the specified multiples of base salary indicated below. These guidelines ensure that they build and maintain a long-term ownership stake in Omnicom’s stock that will align their financial interests with the interests of the Company’s shareholders. The applicable guidelines for Messrs. Wren and Weisenburger are as follows:

	Ownership Target
Position of Executive Officer	Multiple of Salary
President and Chief Executive Officer of Omnicom	6 x Annual Base Salary
Chief Financial Officer of Omnicom	3 x Annual Base Salary

     The guidelines were adopted in the first quarter of 2010 and the executives have five years from the date of the adoption of these guidelines to attain the ownership levels. For purposes of these guidelines, the value of an executive’s stock ownership includes all shares of the Company’s common stock owned by the executive outright (inclusive of unvested equity awards such as restricted shares and restricted stock units) or held in trust for the executive and his or her immediate family, plus the executive’s vested deferred stock and allocated shares of the Company’s common stock in employee plans.

22

     Compensation Forfeiture/Clawback Policy. Our Board has adopted an Executive Compensation Clawback Policy covering compensation paid with respect to any period beginning on or after January 1, 2010, to certain of our officers, including our named executive officers. Under this policy, in the event of a material restatement of our financial statements that is caused by a fraudulent or intentionally illegal act of one of our officers, the non-management members of the Executive Committee of our board (the “Clawback Committee”) will review the annual performance-based cash bonus paid and any performance-based equity awards granted to such officer with respect to the period covered by the restatement. If the Clawback Committee determines that the amount of such awards would have been lower had they been determined based on such restated financial statements, it may seek to recover the after-tax portion of the difference, including, with respect to equity awards, any gain realized on the sale of any such shares.

     Equity Compensation Policies. Omnicom has adopted a policy regarding grants of equity awards, which provides, among other things, that grants of equity awards to non-employee members of the Board shall be approved by the full Board and any other grants must be approved by the Compensation Committee. With limited exception, the grant date of any equity award will be the date of the Board or Committee meeting at which the award is approved and the exercise price, if applicable, will be no less than the closing price of Omnicom’s common stock on such date.

     SERCR Plan and Executive Salary Continuation Plan Agreements

     Omnicom has entered into Award Agreements with Messrs. Wren, Weisenburger and Angelastro pursuant to the Senior Executive Restrictive Covenant and Retention Plan, which was adopted in December 2006 (the “SERCR Plan”) and an Executive Salary Continuation Plan Agreement with Mr. Hewitt. These arrangements are discussed in greater detail in the section below entitled “Potential Payments Upon Termination of Employment or Change in Control.”

     Participation in the SERCR Plan was determined to be offered to participating named executive officers by the Compensation Committee based on the value of the benefit provided to Omnicom through the restrictive covenants contained in the SERCR Plan, as a retention mechanism to seek to secure the services of the participating named executive officers by providing post-employment benefits, subject to a minimum period of employment and based on the Compensation Committee’s analysis of the future financial impact of various termination payout scenarios on each of these recipients and on Omnicom. In making the decision to extend these benefits, the Compensation Committee relied on the advice of its independent compensation consultant, Cook & Co., that the program is representative of market practice, both in terms of design and cost. Amounts payable to Mr. Hewitt under his Executive Salary Continuation Plan Agreement are based on past company practice and are in consideration for the covenants to consult and not to compete during the service period of the agreement. The Compensation Committee believes that these benefits are essential in helping Omnicom fulfill its objectives of attracting and retaining key executive talent.

     Deferred Restricted Stock and Restricted Stock Unit Plans. Each of our named executive officers is eligible to defer, at his election, some or all of the shares of restricted stock and restricted stock units that otherwise would have vested. The shares or units may be deferred until either a date selected by the executive officer or until termination of employment. Omnicom pays participants an amount equal to the cash dividends that would have been paid on the shares or units in the absence of a deferral election, subject to the participant’s employment with Omnicom on the record date of such dividends. No NEO deferred shares of restricted stock or restricted stock units in 2011. Balance and payment information with respect to prior elections is reflected in the Nonqualified Deferred Compensation Table on page 30 below.

     Policy Regarding Death Benefits. On February 10, 2011, Omnicom’s Board of Directors adopted a policy regarding death benefits, which provides, among other things, that shareholder approval is required for any future compensation arrangements that would require the Company to make payments, grants or awards following the death of a named executive officer in the form of unearned salary or bonuses, accelerated vesting or the continuation in force of unvested equity grants, awards of ungranted equity or perquisites. The policy would not apply to payments, grants or awards of the sort offered to other Company employees and does not apply to arrangements existing at the time the policy was adopted.

23

     Benefits and Perquisites

     Retirement Savings Plan. Omnicom participates in the Omnicom Group Retirement Savings Plan, which is a tax-qualified defined contribution plan. All employees who meet the Plan’s eligibility requirements may elect to participate in the 401(k) feature of the Plan and may also receive a company matching and/or profit sharing contribution based on the Plan’s provisions and the discretion of Omnicom.

     Omnicom also makes discretionary profit-sharing contributions after the end of the Plan year. The amount contributed is a percentage of eligible compensation, up to the limitations imposed by the Internal Revenue Code.

    Insurance. Omnicom pays employer premiums for life insurance for each named executive officer.

     Other perquisites. We procure aircraft usage from an unrelated third-party vendor. In some instances, Omnicom makes available to the named executive officers personal use of corporate aircraft hours. The dollar amount reported in the Summary Compensation Table for personal use of aircraft hours reflects the aggregate incremental cost to Omnicom, based on payments we make which are equal to the vendor’s hourly charge for such use and landing fees, minus the amount Omnicom is reimbursed by the executive for his use on the aircraft. Each executive reimburses Omnicom for at least the amount calculated based on the Standard Industry Fare Level (SIFL) tables prescribed under IRS regulations promptly after the cost of the flight is incurred. Additional perquisites and benefits are set forth in the notes to the Summary Compensation Table on page 26.  

     Accounting and Tax Considerations

     IRC Section 162(m)

     Section 162(m) limits the tax deduction for compensation in excess of $1 million paid in any one year to its Chief Executive Officer and certain other executive officers unless the compensation is “qualified performance-based compensation.” Payments of bonuses will constitute “qualified performance-based compensation” under the provisions of Section 162(m) if payable on account of the attainment of one or more pre-established, objective performance goals and if certain requirements are met. Omnicom’s Incentive Bonus Plan and Amended and Restated 2007 Incentive Award Plan (our “2007 Plan”) were each approved by its shareholders pursuant to the requirements of Section 162(m) and Omnicom typically intends for awards earned under these plans to qualify for tax deduction. However, the Compensation Committee reserves the right to pay Omnicom’s employees, including participants in the Incentive Bonus Plan, other amounts which may or may not be deductible under Section 162(m) or other provisions of the Internal Revenue Code.

     The Compensation Committee considers the anticipated tax treatment to Omnicom in its review and establishment of compensation programs and awards. The Compensation Committee intends to continue to consider the deductibility of compensation as a factor in assessing whether a particular arrangement is appropriate given the goals of maintaining a competitive executive compensation system generally, motivating executives to achieve corporate performance objectives and increasing shareholder value.

     Accounting for Share-Based Compensation

     Omnicom accounts for share-based compensation including its restricted stock, restricted stock units and stock option awards in accordance with Financial Accounting Standards Board Accounting Standards Codification Topic 718 (“ASC Topic 718”), Compensation — Stock Compensation.

(1)  These columns show the potential value of the payout for each named executive officer under the Incentive Bonus Plan for the threshold, target and maximum goals in connection with the 2011 performance measures. The potential payouts were performance-driven and therefore entirely at risk. The business measurements and performance criteria for determining the payout are described in the section entitled “Compensation Discussion and Analysis for 2011” on page 12. Awards paid for performance in 2011 are reflected in the Summary Compensation Table for 2011 on page 26.

Nonqualified Deferred Compensation in 2011

     Certain of Omnicom’s employees are eligible to defer some or all of the shares of their restricted stock and restricted stock units that may vest in a given year. For additional information about the deferral plans pursuant to which these elections may be made, see the description of deferred compensation in the section entitled “Compensation Discussion and Analysis” on page 12.

     The table below provides information on the non-qualified deferred compensation of the named executive officers in 2011, which consisted only of the deferral of shares of restricted stock or restricted stock units under Omnicom’s Restricted Stock and Restricted Stock Unit Deferred Compensation Plans.

Potential Payments Upon Termination of Employment or Change in Control

     Each named executive officer participates in our Incentive Bonus Plan; Messrs. Wren, Weisenburger and Angelastro participate in our SERCR Plan; and Mr. Hewitt has entered into an Executive Salary Continuation Plan Agreement with Omnicom. As further described below, participants in our Incentive Bonus Plan are not entitled to payment due to termination of employment or change in control, participants in the SERCR Plan are entitled to payments upon termination of employment under certain circumstances and the Executive Salary Continuation Plan Agreement provides for payment upon termination of employment under certain circumstances. Our named executive officers also hold stock options and/or stock awards, which are subject to accelerated vesting upon termination of employment under certain circumstances or upon a change in control. In addition, Messrs. Wren, Weisenburger, Hewitt and O’Brien receive company-paid life insurance benefits in connection with which a lump sum amount in excess of coverage generally available to all salaried employees would be received upon the named executive officer’s termination of employment due to death. Except for these arrangements, none of the named executive officers have entered into any plans, arrangements or agreements with Omnicom providing for payments upon termination of employment or change in control of Omnicom, other than payments generally available to all salaried employees that do not discriminate in scope, terms or operation in favor of the executive officers of Omnicom.

     The SERCR Plan

     Omnicom adopted the SERCR Plan in 2006, and the Compensation Committee selected Messrs. Wren, Weisenburger and Angelastro to participate and enter into Award Agreements with Omnicom. The SERCR Plan is unique in its structure and objectives. It is a multi-faceted device that provides security to Omnicom through the restrictive covenants described below while delivering a valuable benefit to executives in the form of post-termination compensation. The SERCR Plan mitigates the need to provide severance benefits to participating executives as the program provides a guaranteed stream of income following termination provided the executive fully complies with his obligations.

30

     Restrictive Covenants and Consulting Obligation

     In consideration for annual benefits from Omnicom, participants in the SERCR Plan are subject to restrictions on competition, solicitation, disparagement, and other willful actions materially harming Omnicom, from the date of termination of employment through the end of the calendar year in which they receive their last annual benefits payment. In addition, prior to age 55, upon 30 days’ written notice from Omnicom, the named executive officers agree to serve as advisors or consultants to Omnicom during the retention payment period, subject to certain limitations.

     Annual Benefits

     The SERCR Plan provides annual benefits to participating executives upon their termination of employment after they render seven years of service to Omnicom or its subsidiaries, unless termination is for “Cause”. “Cause” is generally defined for this purpose as the executive having been convicted of (or having entered a plea bargain or settlement admitting guilt for) any felony committed in the execution of and while performing his duties as an executive officer, an act of fraud or embezzlement against Omnicom, as a result of which continued employment would have a material adverse impact on Omnicom, or having been the subject of any order, judicial or administrative, obtained or issued by the SEC, for any securities violation involving a material and willful act of fraud. Subject to compliance with the SERCR Plan’s restrictive covenants and consulting obligation, the annual benefit is payable for 15 years following termination, and is equal to the lesser of (a) the product of (i) the average of the executive’s three highest years of total pay (base salary plus bonus and other incentive compensation), and (ii) a percentage equal to 5% plus 2% for every year of the executive’s service as an executive officer to Omnicom, not to exceed 35% and (b) $1.5 million, subject to an annual cost-of-living adjustment. Payment of this annual benefit begins on the later of (a) attainment of age 55, or (b) the year following the calendar year in which the termination of employment occurred, with certain exceptions. In the event of death subsequent to satisfaction of the seven-year service requirement, beneficiaries of the executive are entitled to the annual benefit payments. No annual benefit is payable if the executive is terminated by Omnicom for Cause.

     The Executive Salary Continuation Plan Agreement

     Omnicom entered into an Executive Salary Continuation Plan Agreement with Mr. Hewitt, pursuant to which Omnicom agrees to make annual payments for up to a maximum of 10 years after termination of full time employment (the “Payment Period”), unless termination is for “Cause,” in consideration for Mr. Hewitt’s agreement to consult and not to compete during the Payment Period. “Cause” is generally defined for this purpose as willful malfeasance, such as breach of trust, fraud or dishonesty. The Payment Period is determined based on Mr. Hewitt’s age and years of service with Omnicom or its subsidiaries, and as of December 31, 2011, the Payment Period was the 10-year maximum for Mr. Hewitt.

     Annual Payments under the Executive Salary Continuation Plan Agreement

     Following termination and subject to compliance with the consulting obligation and agreement not to compete, Mr. Hewitt is entitled to receive annual payments, beginning in the year described below, for the duration of the Payment Period. Annual payments are equal to the lesser of (a) 30% of the highest annual salary paid to Mr. Hewitt within five years prior to termination and (b) a percentage of the net profits of Omnicom for the calendar year immediately prior to the year in which the named executive officer is entitled to payment (the “Annual Payment”).

     Mr. Hewitt is entitled to 100% of the Annual Payment in the event of disability or termination by Omnicom without Cause. For a voluntary termination, including retirement, Mr. Hewitt is entitled to 100% of the Annual Payment since he has completed 20 years of service. In the event of death, beneficiaries of Mr. Hewitt are entitled to 75% of the Annual Payment. Mr. Hewitt is not entitled to any Annual Payment if he is terminated by Omnicom for Cause.

     Consulting Obligation and Certain Restrictive Covenants

     On 30 days’ notice, Mr. Hewitt agrees to serve as an advisor or consultant to Omnicom during the Payment Period, subject to certain limitations. In addition, he will be subject to restrictions on competition and other willful actions harming Omnicom, from the date of termination through the end of the Payment Period.

31

     The Incentive Bonus Plan

     Omnicom has adopted an Incentive Bonus Plan, and the Compensation Committee has chosen each of the named executive officers to participate in it. The Incentive Bonus Plan provides performance-based bonuses to participants, based upon specific performance criteria, discussed above in the section entitled “Compensation Discussion and Analysis” on page 12, during each performance period. If a participant in the Incentive Bonus Plan experiences a termination of employment for any reason prior to the end of a performance period or the bonus payment date for such performance period, he is not entitled to any payment, but the Compensation Committee has discretion (a) to determine whether the participant will receive any bonus, (b) to determine whether the participant will receive a pro-rated bonus reflecting that portion of the performance period in which the participant had been employed by Omnicom, and (c) to make such other arrangements as the Compensation Committee deems appropriate in connection with the participant’s termination of employment.

     Executive Life Insurance Coverage

     Omnicom provides life insurance coverage to their respective employees. Certain of the named executive officers participate in company-sponsored executive life insurance programs that entitle them to a larger coverage amount than they would otherwise be entitled to as employees. Specifically, Messrs. Wren, Weisenburger, Hewitt and O’Brien have supplemental life insurance coverage for which Omnicom pays the premiums. In the event of termination of employment due to death on December 31, 2011, these named executive officers would each be entitled to a supplemental life insurance benefit in the amount of $250,000 paid by MassMutual.

     Acceleration of Equity Awards

     Messrs. Wren, Weisenburger, Angelastro, and O’Brien hold unvested stock options and performance restricted stock units pursuant to our 2007 Plan. Messrs. Angelastro and O’Brien hold restricted stock units pursuant to our 2007 Plan and restricted stock pursuant to our prior equity incentive plan, The Omnicom Group Inc. Equity Incentive Plan (the “Equity Incentive Plan”). Mr. Hewitt holds performance restricted stock units pursuant to our 2007 Plan and restricted stock pursuant to both our 2007 Plan and Equity Incentive Plan. As specified below, such named executive officers are entitled to accelerated vesting (a) on a pro rata basis upon termination of employment due to disability (b) upon death, (c) upon a change in control of Omnicom and (d) subject to certain conditions, upon retirement.

     Stock Options

     Unvested options granted pursuant to the 2007 Plan vest in full and are exercisable through the end of the option term if (a) the named executive officer terminates due to death or (b) a change in control of Omnicom occurs. For awards made after February 12, 2009, if the named executive officer’s age plus years of service equals 80 or more and he retires after the first anniversary of the grant date, such options vest in full and are exercisable through the 36-month period immediately following retirement or, if sooner, the end of the option term. Currently, Mr. Wren is the only named executive officer whose age plus years of service equals 80 or more. Unvested options granted pursuant to the 2007 Plan vest on a pro rata basis and are exercisable through the end of the option term if the named executive officer terminates employment due to disability. Such unvested options are automatically cancelled due to a termination of employment for any other reason.

     Restricted Stock, Restricted Stock Units and Performance Restricted Stock Units

     Restricted stock, restricted stock units and performance restricted stock units, as applicable, granted in 2007 pursuant to the Equity Incentive Plan or thereafter under the 2007 Plan fully vest in the event of a change in control of Omnicom or if the named executive officer terminates due to death, and vest on a pro rata basis if the named executive officer terminates employment due to disability. If the named executive officer retires, voluntarily terminates or is terminated by Omnicom, with or without cause, all restricted stock, restricted stock units and performance restricted stock units granted pursuant to the Equity Incentive Plan or the 2007 Plan that have not yet vested are forfeited and, in the case of restricted stock awards made before February 10, 2011, Omnicom reimburses the named executive officer for the par value of $0.15 per share paid by that officer at grant.

32

Potential Payments Upon Termination of Employment or Change in Control

     The following table provides the potential payments that each named executive officer may receive upon termination of employment or change in control of Omnicom, assuming that (a) such termination or change in control of Omnicom occurred on December 31, 2011, and (b) the price per share of Omnicom common stock equals $44.58, the closing price at 2011 fiscal year end.

(1)	Except in the event of a termination for Cause, Mr. Wren or his beneficiary, as the case may be, would be entitled to receive fifteen annual payments in this amount, the first of which would be payable in 2012. Mr. Wren would not be entitled to any payments in the event of termination for Cause. The amount reported is the payment cap set forth in the SERCR Plan as in effect on December 31, 2011, such amount being subject to an annual cost-of-living adjustment. All payment obligations are conditioned upon compliance with the restrictive covenants and consulting obligation described above.
(2)	As discussed above, upon a termination of employment for any reason prior to the end of a performance period or prior to the bonus payment date for such performance period, the participant is not entitled to any award. The Compensation Committee, however, has discretion to determine whether awards should be made pursuant to the Incentive Bonus Plan and the amounts of such awards. A termination of employment on December 31, 2011 would fall prior to the bonus payment date for the 2011 performance period. The amounts reported in the table assume that the Compensation Committee in its discretion authorized a payment equal to the target bonus amounts, except in the event of a for cause termination, in which case it is assumed that the Compensation Committee would not grant an award.
(3)	The value of any stock options was determined by taking the aggregate fair market value, as of 2011 fiscal year end, of the common stock underlying stock options subject to accelerated vesting, and subtracting the aggregate exercise price for such stock options. The value of restricted stock, restricted stock units and performance restricted stock units was determined by taking the aggregate fair market value of the shares of restricted stock (or the shares underlying restricted stock units and performance restricted stock units) subject to accelerated vesting as of 2011 fiscal year end. The value of performance restricted stock units assumes achievement of the highest performance target and therefore the actual value could be lower than the amount disclosed. Also, the value of restricted stock has not been adjusted to reflect any par value paid by the executive for such stock on the date of grant.
(4)	Except in the event of termination due to death or disability or a termination for Cause, Mr. Weisenburger would be entitled to receive fifteen annual payments in this amount, the first of which would be payable in 2013 upon Mr. Weisenburger turning fifty-five. In the event of termination due to death or disability, Mr. Weisenburger or his beneficiary, as the case may be, would be entitled to receive fifteen annual payments in this amount, the first of which would be payable in 2012. Mr. Weisenburger would not be entitled to any payments in the event of termination for Cause. The amount reported is the payment cap set

	forth in the SERCR Plan as in effect on December 31, 2011, such amount being subject to an annual cost- of-living adjustment. All payment obligations are conditioned upon compliance with the restrictive covenants and consulting obligation described above.
(5)	Except in the event of termination due to death or disability or a termination for Cause, Mr. Angelastro would be entitled to receive fifteen annual payments in this amount, the first of which would be payable in 2019 upon Mr. Angelastro turning fifty-five. In the event of termination due to death or disability, Mr. Angelastro or his beneficiary, as the case may be, would be entitled to receive fifteen annual payments in this amount, the first of which would be payable in 2012. Mr. Angelastro would not be entitled to any payments in the event of termination for Cause. All payment obligations are conditioned upon compliance with the restrictive covenants and consulting obligation described above.
(6)	This reflects 75% of Mr. Hewitt’s $118,500 annual payment, payable to his designated beneficiary. Ten annual payments in this amount would be paid to such beneficiary, with the first payment being made in 2012.
(7)	This reflects 30% of the highest annual rate of salary paid to Mr. Hewitt in the five years preceding December 31, 2011. Ten annual payments would be made in this amount, with the first payment being made in 2013. All payment obligations are conditioned upon compliance with the consulting obligation and agreement not to compete described above.

DIRECTORS’ COMPENSATION FOR FISCAL 2011

     Directors who are also current or former employees of Omnicom or its subsidiaries receive no compensation for serving as directors. The compensation program for directors who are not current or former employees of Omnicom or its subsidiaries is designed to compensate directors in a manner that is reflective of the work required for a company of Omnicom’s size and composition and to align directors’ interests with the long-term interests of shareholders. The table below includes the following compensation elements with respect to non-employee directors:

     Annual Compensation. Non-employee directors are paid a cash annual retainer of $60,000 and $2,000 for attendance at a Board or Committee meeting. In addition, directors receive reimbursement for customary travel expenses.

     In accordance with our 2007 Plan, and our Director Compensation and Deferred Stock Program adopted by our Board on December 4, 2008, non-employee directors also receive fully-vested common stock each fiscal quarter. For each of the four quarters in 2011, such directors received common stock with a fair value of $25,000 based on the per share closing price of our common stock on the date prior to grant.

     Our Director Compensation and Deferred Stock Program and 2007 Plan provide that each director may elect to receive all or a portion of his or her cash director compensation for the following year’s service in common stock. Messrs. Henning and Murphy and Mses. Denison and Johnson Rice each elected to receive all or a portion of their respective 2011 cash director compensation in common stock.

     Directors may also elect to defer any common shares payable to them, which will be credited to a bookkeeping account in the directors’ names. These elections generally must be made prior to the start of the calendar year for which the fees would be payable. The number of shares of common stock delivered or credited to a director’s account is based on the fair market value of our common stock on the first trading day immediately preceding the date the fees would have been paid to the director. Each director other than Mr. Roubos elected to defer common shares payable to them in 2011.

     Chairman Fees. The Chairs of our Committees receive the following additional annual fees in cash due to the workload and the additional responsibilities of their positions. The Chair of our Audit Committee receives an additional fee of $20,000 each year. The Chairs of our Finance, Compensation, Governance and Executive Committees each receive an additional fee of $10,000 each year, as long as such Chair is not also an executive of Omnicom. In 2011, only the Chairs of the Compensation, Governance and Executive Committees received the $10,000 fee.

For a discussion of the assumptions used to calculate the fair value of stock awards, refer to notes 3 and 12 to the consolidated financial statements contained in our 2011 10-K. The fair market value for each quarterly stock award was $25,000 for each individual reported in the table above.

EQUITY COMPENSATION PLANS

     Our principal equity plan for employees is our 2007 Plan, which was approved by shareholders at our 2007 Annual Meeting of Shareholders, amended at our 2010 Annual Meeting of Shareholders, and replaced both (i) all prior employee equity incentive plans and (ii) our Director Equity Plan, which was approved by shareholders at our Annual Meeting of Shareholders in 2004. The Compensation Committee’s independent compensation consultant, Cook & Co., provided analysis and input on the 2007 Plan. As a result of the adoption of the 2007 Plan, no new awards may be made under any of Omnicom’s prior equity plans. Outstanding equity awards under prior plans, however, were not affected by the adoption of our 2007 Plan.

     The purpose of the 2007 Plan is to promote the success and enhance the value of Omnicom by continuing to link the personal interest of participants to those of Omnicom shareholders and by providing participants with an incentive for outstanding performance to generate superior returns to Omnicom shareholders. The 2007 Plan provides for the grant of stock options (both incentive stock options and nonqualified stock options), restricted stock, stock appreciation rights, performance shares, performance stock units, dividend equivalents, stock payments, deferred stock, and restricted stock units.

     Persons eligible to participate in the 2007 Plan include all employees and consultants of Omnicom and its subsidiaries, members of our Board or, as applicable, members of the board of directors of a subsidiary, as determined by the committee administering the 2007 Plan (the “IAP Committee”). The IAP Committee is appointed by our Board, and currently is comprised of the members of our Compensation Committee. With respect to awards to independent directors, Omnicom’s Board administers the 2007 Plan.

     All of our current equity compensation plans have been approved by shareholders. The following table provides information about our current equity compensation plans as of December 31, 2011.

Plan Category	Number of securities to be issued upon exercise of outstanding options, warrants and rights (#)	Weighted-average exercise price of outstanding options, warrants and rights ($/shr)		Number of securities remaining available for future issuance (#)

Equity compensation plans not approved
by security holders	—		—	—
Total	18,301,409	$	26.22	15,855,331

(1)

The maximum number of shares that may be issued under our 2007 Plan pursuant to awards granted after May 25, 2010 is 17,000,000. This number is subject to upward adjustment since awards granted under the 2007 Plan prior to such date or under previously adopted plans (“Prior Plans”) that are forfeited or expire may be used again under the 2007 Plan. Any share of common stock that is subject to an option or stock appreciation right granted from our 2007 Plan is counted against this limit as one share of common stock for every one share of common stock granted. Any share of common stock that is subject to an award other than an option or stock appreciation right granted from the 2007 Plan is counted against this limit as 2.5 shares of common stock for every one share of common stock granted. The figure above includes 6,299,646 shares that may be issued under our 2007 Plan, which assumes that all securities available for future issuance are subject to options or stock appreciation rights. If all securities available for future issuance were subject to awards other than options or stock appreciation rights, this figure would be 2,519,858. Our 2007 Plan provides that we may no longer grant any awards under our Prior Plans. As of December 31, 2011, there were 18,301,409 stock options outstanding under our equity compensation plans (other than our ESPP) with a weighted-average exercise price of $26.22 and a weighted-average term of 6.73 years and 6,452,887 unvested full value shares outstanding under our equity compensation plans (other than our ESPP).

(2)

The ESPP is a tax-qualified plan in which all eligible full-time and part-time domestic employees may participate.

STOCK OWNERSHIP

     The following table sets forth certain information as of the close of business on February 29, 2012 (except as otherwise noted), with respect to the beneficial ownership of our common stock by:

• each person known by Omnicom to own beneficially more than 5% of our outstanding common stock;

• each current director or nominee;

• each named executive officer; and

• all directors and executive officers as a group.

     The amounts and percentages of shares beneficially owned are reported on the basis of SEC regulations governing the determination of beneficial ownership of securities. Under SEC rules, a person is deemed to be a “beneficial owner” of a security if that person has or shares voting power or investment power, which includes the power to dispose of or to direct the disposition of such security. A person is also deemed to be a beneficial owner of any securities of which that person has a right to acquire beneficial ownership within 60 days. Securities that can be so acquired are deemed to be outstanding for purposes of computing such person’s ownership percentage, but not for purposes of computing any other person’s percentage. Under these rules, more than one person may be deemed to be a beneficial owner of the same securities and a person may be deemed to be a beneficial owner of securities as to which such person has no economic interest. Unless otherwise indicated, the address for each individual listed below is c/o Omnicom Group Inc., 437 Madison Avenue, New York, New York 10022.

AUDIT RELATED MATTERS

Fees Paid to Independent Auditors

     The following table shows information about fees billed by KPMG LLP and affiliates for professional services (as well as all “out-of-pocket” costs incurred in connection with these services) rendered for the last two fiscal years:

	2011		Approved by Audit Committee		2010		Approved by Audit Committee
Audit Fees (1)	$	21,464,000	100	%	$	22,058,721	100	%
Audit-Related Fees (2)	$	907,969	100	%	$	1,360,157	100	%
Tax Fees (3)	$	660,655	100	%	$	677,441	100	%
All Other Fees (4)	$	6,090	100	%	$	12,000	100	%
Total Fees	$	23,038,714			$	24,108,319

(1)	Audit Fees consist of fees for professional services for the audit or review of our consolidated financial statements and for the audit of our internal control over financial reporting or for audit services that are normally provided by independent auditors in connection with statutory and regulatory filings or engagements.
(2)	Audit-Related Fees consist of fees for assurance and related services that are reasonably related to the performance of the audit or review of our consolidated financial statements and are not reported under Audit Fees, including due diligence related to mergers and acquisitions and special procedures to meet certain statutory requirements.
(3)	Tax Fees consist primarily of fees for tax compliance including the review and preparation of statutory tax returns and other tax compliance related services.
(4)	All Other Fees consist of permitted services other than those that meet the criteria above. In 2011, this amount is in respect to training activities, whereas in 2010 this amount relates to an information technology risk assessment against certain criteria as determined by management.

     In deciding to reappoint KPMG LLP to be our auditors for 2012, the Audit Committee considered KPMG LLP’s provision of services to assure that it was compatible with maintaining KPMG LLP’s independence. The Committee determined that these fees were compatible with the independence of KPMG LLP as our independent auditors.

     The Audit Committee has adopted a policy that requires it to pre-approve each audit and permissible non-audit service rendered by KPMG LLP except for items exempt from pre-approval requirements by applicable law. On a quarterly basis, the Audit Committee reviews and generally pre-approves specific types of services and the range of fees that may be provided by KPMG LLP without first obtaining specific pre-approval from the Audit Committee. The policy requires the specific pre-approval of all other permitted services and all other permitted services were pre-approved in 2011.

Audit Committee Report

     The Audit Committee’s primary purpose is to assist the Board in carrying out its oversight responsibilities relating to Omnicom’s financial reporting. Management is responsible for the preparation, presentation and integrity of Omnicom’s financial statements, accounting and financial reporting principles and the establishment and effectiveness of internal controls and procedures designed to ensure compliance with accounting standards and applicable laws and regulations. The independent auditors are responsible for performing an independent audit of the financial statements in accordance with the standards of the Public Company Accounting Oversight Board (United States), expressing an opinion as to the conformity of such financial statements with generally accepted accounting principles and auditing the operating effectiveness of internal control over financial reporting. The independent auditors have free access to the Audit Committee to discuss any matters they deem appropriate.

40

     In performing its oversight role, the Audit Committee has reviewed and discussed with management Omnicom’s audited 2011 financial statements as of December 31, 2011. The Committee has also discussed with KPMG LLP the matters required to be discussed under all relevant professional and regulatory standards, which included discussion of the quality of Omnicom’s accounting principles, the reasonableness of significant judgments and the clarity of disclosures in the financial statements. The Committee has received and reviewed the written disclosures and the letter from KPMG LLP required under all relevant professional and regulatory standards, and has discussed with KPMG LLP its independence.

     Based on the review and discussions referred to in this Report, the Audit Committee recommended to the Board that the audited financial statements of Omnicom for the year ended December 31, 2011 be included in its Annual Report on the 2011 10-K.

ITEMS TO BE VOTED ON

Item 1 — Election of Directors

     The current 13 members of the Board have been nominated to continue to serve as directors for another year. All of the nominees have been recommended for re-election to the Board by our Governance Committee and approved and nominated for re-election by the Board.

     The Board has no reason to believe that any of the nominees would be unable or unwilling to serve if elected. If a nominee becomes unable or unwilling to accept nomination or election, the Board prior to the meeting may select a substitute nominee or undertake to locate another director after the meeting. If you have submitted a proxy and a substitute nominee is selected, your shares will be voted for the substitute nominee.

     In accordance with our By-laws, directors are elected by a majority of the votes cast. That means the nominees will be elected if the number of votes cast “for” a director’s election exceeds the number of votes cast “against” such nominee. For this purpose, abstentions and broker non-votes will not count as a vote cast. Our form of proxy permits you to abstain from voting “for” or “against” a particular nominee. However, shares represented by proxies so designated will count as being present for purposes of determining a quorum but will have no effect on the election of directors. Such proxies may also be voted on other matters, if any, that may be properly presented at the meeting.

     If an incumbent nominee is not reelected, New York law provides that the director would continue to serve on the Board as a “holdover director.” Under our By-laws and a policy adopted by the Board, such a director is required to promptly offer to tender his or her resignation to the Board. The Governance Committee of the Board then must consider whether to accept the director’s resignation and make a recommendation to the Board. The Board will then consider the resignation, and within 90 days after the date of certification of the election results, publicly disclose its decision and the reasons for its decision. A director whose resignation is under consideration may not participate in any deliberation regarding his or her resignation unless none of the directors received a majority of the votes cast. If the Board accepts a director’s resignation, the Board will then elect a replacement in accordance with the By-laws.

The Board UNANIMOUSLY recommends that shareholders vote FOR all nominees.

Item 2 — Ratification of the Appointment of Independent Auditors

     In accordance with the Audit Committee’s charter, the Audit Committee has appointed KPMG LLP as our independent auditors for our fiscal year ending December 31, 2012. We are submitting the selection of our independent auditors for shareholder ratification at the 2012 Annual Meeting. KPMG LLP has been our independent auditor since June 2002.

     Representatives of KPMG LLP are expected to be present at the 2012 Annual Meeting, will have the opportunity to make a statement if they desire to do so and are expected to be available to respond to appropriate questions.

     The Audit Committee is not bound by the results of the vote regarding ratification of the independent auditors. If our shareholders do not ratify the selection, the Audit Committee will reconsider whether to retain KPMG LLP, but still may retain them. Even if the selection is ratified, the Audit Committee, in its discretion, may change the appointment at any time during the year if it determines that such a change would be in the best interests of Omnicom and its shareholders.

     The Board UNANIMOUSLY recommends that shareholders vote FOR ratification of the appointment of KPMG LLP as our independent auditors.

     Approval of this proposal requires the favorable vote of the holders of a majority of the shares voting on the proposal. Abstentions and broker non-votes will have no effect on the outcome of this proposal.

46

Item 3 — Approval of By-law Amendment to Provide that Holders of at Least 25% of the Combined Voting Power of the Company’s Outstanding Capital Stock May Request a Special Meeting of Shareholders

     The Board recommends that shareholders approve our proposal to amend the By-laws to enable one or more shareholders holding not less than 25% of the voting power of the Company to call a special meeting of shareholders. The Board recommends a vote “for” this proposal.

     Summary of Proposed Amendment

     Omnicom’s By-laws currently provide that special meetings of shareholders may be called by the Board of Directors or the President and must be called by the President or the Secretary upon the written request of a majority of the Board of Directors. This proposal would amend Article I, Section 4 of the By-laws to allow, in addition to the foregoing, one or more shareholders holding not less than 25% of the voting power of the Company to call a special meeting of shareholders.

     The Board is committed to strong corporate governance practices. The Governance Committee and the Board have considered the issue of shareholders’ ability to call a special meeting and determined that it is in the best interest of Omnicom and its shareholders to allow one or more shareholders holding not less than 25% of the voting power of the Company to call a special meeting of shareholders.

     Proposed Amendments

     Adding a shareholders’ right to call a special meeting to Omnicom’s governing documents will require an amendment to Article I, Section 4 of the By-laws, which would read as follows:

SECTION 4. Special Meetings.

(a) Special meetings of shareholders may be called at any time for any purpose or purposes, by the Board of Directors or the President, and shall be called by the President or the Secretary upon the written request of a majority of the Board of Directors. A special meeting of shareholders shall be called by the Secretary upon the written request of the record holders of at least twenty-five percent (25%) of the combined voting power of outstanding capital stock of the Corporation (the “Requisite Percent”), subject to Subsection (b) of this Section 4 (a “Shareholder Requested Special Meeting”). A request shall state the purpose or purposes of the proposed meeting.

(b) In order for a Shareholder Requested Special Meeting to be called, one or more requests for a special meeting (each, a “Shareholder Special Meeting Request,” and collectively, the “Shareholder Special Meeting Requests”) must be signed by the Requisite Percent of record holders (or their duly authorized agents) and must be delivered to the Secretary. The Shareholder Special Meeting Request(s) shall be delivered to the Secretary at the principal executive offices of the Corporation by registered mail, return receipt requested. Each Shareholder Special Meeting Request shall (i) set forth a statement of the specific purpose(s) of the meeting and the matters proposed to be acted upon at such meeting, (ii) bear the date of signature of each such shareholder (or duly authorized agent) signing the Shareholder Special Meeting Request, (iii) set forth (A) the name and address, as they appear in the Corporation’s stock ledger, of each shareholder signing such request (or on whose behalf the Shareholder Special Meeting Request is signed), (B) the class, if applicable, and the number of shares of capital stock of the Corporation that are owned of record and beneficially by each such shareholder and (C) include documentary evidence of such shareholder’s record and beneficial ownership of such stock and (iv) set forth all information relating to each such shareholder as required by Article I, Section 2(i) and (ii) of these By-laws. Any requesting shareholder may revoke his, her or its request for a special meeting at any time by written revocation delivered to the Secretary at the principal executive offices of the Corporation.

(c) The Secretary shall not be required to call a special meeting of shareholders if (i) the Board of Directors calls an annual or special meeting of shareholders to be held not later than sixty (60) days after the date on which a valid Shareholder Special Meeting Request or Shareholder Special Meeting Requests have been delivered to the Secretary (the “Delivery Date”), or (ii) the Shareholder Special Meeting Request or Shareholder Special Meeting Requests (A) are received by the Secretary during the period commencing seventy-five (75) days prior to the first anniversary of the date of the

47

immediately preceding annual meeting and ending on the date of the next annual meeting, (B) contains an identical or substantially similar item (a “Similar Item”) to an item that was presented at any meeting of shareholders held within one hundred and twenty (120) days prior to the Delivery Date (and, for purposes of this clause (B) the election of directors shall be deemed a “Similar Item” with respect to all items of business involving the election or removal of directors), (C) relates to an item of business that is not a proper subject for action by the party requesting the special meeting under applicable law, (D) was made in a manner that involved a violation of Regulation 14A under the Securities Exchange Act of 1934, as amended, or other applicable law, or (E) does not comply with the provisions of this Section 4.

(d) Except as provided in the next sentence, any special meeting shall be held at such date and time as may be fixed by the Board of Directors in accordance with these By-laws and the New York Business Corporation Law. In the case of a Shareholder Requested Special Meeting, such meeting shall be held at such date and time as may be fixed by the Board of Directors; provided, however, that the date of any Shareholder Requested Special Meeting shall be not more than sixty (60) days after the record date for such meeting (the “Meeting Record Date”), which shall be fixed in accordance with Article VI, Section 4 of these By-laws. In fixing a date and time for any Shareholder Requested Special Meeting, the Board of Directors may consider such factors as it deems relevant within the good faith exercise of business judgment, including, without limitation, the nature of the matters to be considered, the facts and circumstances surrounding any request for a meeting and any plan of the Board of Directors to call an annual meeting or a special meeting.

(e) Business to be transacted at a special meeting may only be brought before the meeting pursuant to the Corporation’s notice of meeting. Business transacted at any Shareholder Requested Special Meeting shall be limited to the purpose(s) stated in the Shareholder Special Meeting Request(s); provided, however, that nothing herein shall prohibit the Board of Directors from submitting matters to the shareholders at any Shareholder Requested Special Meeting.

The Board UNANIMOUSLY recommends a vote FOR the approval of the amendments to the Company’s By-laws to enable shareholders to call a special meeting.

     Approval of this proposal requires the favorable vote of the holders of a majority of the shares voting on the proposal. Abstentions and broker non-votes will have no effect on the outcome of this proposal.

Item 4 —Advisory Vote on Executive Compensation

     In accordance with the Dodd-Frank Wall Street Reform and Consumer Protection Act and Section 14A of the Securities Exchange Act of 1934, as amended, we are asking shareholders to approve an advisory resolution on the compensation of the Company’s named executive officers as reported in this Proxy Statement. Last year, the Board recommended that this advisory vote to approve named executive officer compensation be conducted annually and shareholders voted in favor of this recommendation by a substantial majority. Accordingly, the Board has determined that it will hold an advisory vote to approve named executive officer compensation annually until the next vote to determine the frequency of such an advisory vote. Subsequent to the advisory vote reflected in this proposal, the next advisory vote to approve named executive officer compensation is expected to occur at our annual shareholders meeting in 2013.

     Our executive compensation programs are designed to support the Company’s long-term success. As described above in the “Compensation Discussion and Analysis” section of this Proxy Statement, the Compensation Committee has structured our executive compensation program to achieve the following key objectives:

• Attract, motivate and retain the talented executives who are a critical component of Omnicom’s long-term success by providing each with a competitive total rewards package; and

• Ensure that executive compensation is aligned with both the short and long-term interests of shareholders.

48

     In 2011, Omnicom, led by our named executive officers, delivered strong financial, operational and creative results. These strategic efforts resulted in broad-based business and financial growth, including:

• Annual revenue growth was 10.6%, the highest since 2007;

• Annual revenue was $13.87 billion and was the highest in the Company’s history;

• EBITA growth was 15.1% and EBITA margin increased 50 basis points to 12.7%;

• All of our industry groups had positive growth and in the aggregate Omnicom led the industry with 6.1% organic growth;

• Full year net income increased over 15% and EPS increased over 23%;

• Return on invested capital and return on equity continued to improve, reaching an industry-leading 18.8% and 26.9%, respectively;

• We accelerated our investments in digital, social, mobile and analytics across the networks;

• We acquired new capabilities to complement our existing skill sets and entered into key strategic partnerships;

• We continued to strengthen our footprint geographically and expand our presence in key emerging markets;

• Our agencies were recognized around the world for their work in 2011;

• We returned over $1 billion to shareholders in 2011; and

• We also increased our dividend by 20%.

     We believe this performance shows the value of our strategy.

     We urge shareholders to read the “Compensation Discussion and Analysis” above, which describes in more detail how our executive compensation policies and procedures operate and are designed to achieve our compensation objectives, as well as the Summary Compensation Table and related compensation tables and narrative above, which provide detailed information on the compensation of our named executive officers. The Compensation Committee and the Board believe that the policies and procedures articulated in the “Compensation Discussion and Analysis” are effective in achieving our goals and that the compensation of our named executive officers reported in this Proxy Statement has supported and contributed to our success.

     We are asking shareholders to approve the following advisory resolution at the 2012 Annual Meeting.

     RESOLVED, that the shareholders of Omnicom Group Inc. (the “Company”) approve, on an advisory basis, the compensation of the Company’s named executive officers, as disclosed in the Company’s Proxy Statement for the 2012 Annual Meeting of Shareholders pursuant to the compensation disclosure rules of the Securities and Exchange Commission, including the Compensation Discussion and Analysis, the Summary Compensation Table for 2011 and the other related tables and disclosure.

     This advisory resolution, commonly referred to as a “say-on-pay” resolution, is non-binding on the Board. Although non-binding, the Board and the Compensation Committee will carefully review and consider the voting results when evaluating our executive compensation program.

The Board UNANIMOUSLY recommends that shareholders vote FOR the advisory resolution on executive compensation.

     Approval of this proposal requires the favorable vote of the holders of a majority of the shares voting on the proposal. Abstentions and broker non-votes will have no effect on the outcome of this proposal.

Item 5 —Shareholder Proposal Regarding Annual Disclosure of EEO-1 Data

     Representatives of the Comptroller of the City of New York, John C. Liu (the “Comptroller”), as trustee and/or custodian of the New York City pension funds (the “Funds”), 1 Centre Street, New York, NY 10007, have advised that the Funds are the beneficial owner of 697,947 shares of Omnicom common stock and that the Comptroller intends to introduce a proposal for the consideration of shareholders at the 2012 Annual Meeting, the text of which reads as follows:

RESOLVED: Shareholders request the Board of Directors to adopt and enforce a policy requiring Omnicom Group, Inc. to disclose its EEO-1 data – a comprehensive breakdown of the Company’s workforce by race and gender across all employment categories – in its annual corporate social responsibility (CSR) or sustainability report, beginning in 2012.

     Supporting Statement

     Despite federal and state laws forbidding employment discrimination on the basis of race, allegations of racial discrimination persists in some industries; and in recent years, a number of companies have agreed to pay millions of dollars in legal settlements of class actions alleging racial discrimination.

     A study addressing racial discrimination in the advertising industry, “Research Perspectives on Race and Employment in the Advertising Industry”, (Bendick and Egan Economic Consultants, Inc. 2009), found that:

• Racial disparity is 38% worse in the advertising industry than in the overall U.S. labor market;

• The “discrimination divide” between advertising and other U.S. industries is more than twice as bad as it was 30 years ago;

• Black college graduates working in advertising earn 80 cents for every dollar earned by their equally-qualified White counterparts;

• About 16% of large advertising firms employ no Black managers or professionals, a rate 60% higher than in the overall labor market; and

• Black managers and professionals in the industry are only one-tenth as likely as their White counterparts to earn $100,000 a year.

     Numerous studies have found that workplace diversity provides a competitive advantage by generating diverse, valuable perspectives, creativity and innovation, increased productivity and morale, while eliminating the limitations of “groupthink”.

     Given compelling evidence of the positive effects of diversity on long-term value creation, Omnicom Group should continuously seek to increase the diversity of its workforce. Full and transparent disclosure of the Company’s EEO-1 data would drive management and the Board of Directors to pursue continuous performance improvements in the Company’s diversity programs, the full integration of diversity into its culture and practices, and the strengthening of its reputation and accountability to its shareholders. In addition, the information could be useful to investors in assessing the Company’s progress on hiring, retaining, and promoting minority and female employees over the long-term.

     Given that the Company annually files an EEO-1 report with the Equal Employment Opportunity Commission, the report could be made available to shareholders at a minimal additional cost.

     We urge shareholders to vote FOR the proposal.

50

The Board’s Statement in Opposition

     The Board of Directors has considered this proposal and concluded that its adoption is unnecessary in light of Omnicom’s existing and active commitment to diversity and not in the best interests of our shareholders. Accordingly, the Board UNANIMOUSLY recommends a vote AGAINST this proposal for the following reasons.

The Company agrees with and has implemented programs supporting the principles of this proposal

     Omnicom agrees with the proponent that workplace diversity creates value for the Company and fosters a positive corporate culture. With our global presence, we believe it is important that our workforce reflects our global community. We are committed to recruiting and retaining the best talent from diverse backgrounds and experiences.

• The Omnicom Diversity Development Advisory Committee (“DDAC”) was formed in 2007 to enhance diversity at Omnicom, and by extension, throughout the advertising industry as a whole. Omnicom has committed its workforce and $1.25 million in funding to this effort. The DDAC is chaired by former New York State Comptroller, H. Carl McCall and its members include Sharon Robinson of Major League Baseball, MarySol Rodriguez of Distinctive Public Affairs, Maria Nunes of SY Partners, Darwin Davis of BACD Enterprises, Sonia Stroka of Porter Novelli and musician and radio personality, James Mtume.

• Through the Omnicom Medgar Evers Associate Program, established in 2009, we have provided financial support and created numerous internships and other opportunities for students with diverse educational, socioeconomic, political and cultural backgrounds.

• Omnicom supports ADCOLOR, an initiative of the ADCOLOR Industry Coalition, which creates networks of outstanding diverse professionals and champions of diversity and inclusion. At the annual ADCOLOR Awards, diverse professionals at all levels within the industry are honored for their personal contributions and efforts to open doors for other high-potential, diverse professionals.

• Our Diversity Initiatives Group meets monthly to share best practices and develop tools to efficiently and effectively incorporate diversity and inclusion initiatives at Omnicom offices.

• G23, a strategic insights organization founded in 2008 by Omnicom’s most senior female executives and distinguished thought leaders, focuses on the economic and social impact of women in the global economy. Together with some of Omnicom’s largest clients, G23 helps lay the foundation for more meaningful engagement and dialog with women at all life stages.

• Omnicom employs a Diversity Professional at each of our networks and a Senior Vice President and Chief Diversity Officer at our corporate office to oversee and advance diversity and inclusion efforts at every level of our organization.

     Omnicom has also taken an active role in developing supplier diversity. In connection with the Omnicom Supplier Diversity Initiative, we created the Omnicom Supplier Diversity Database in order to expand access to diverse suppliers across our global network of agencies. The database is a resource that spurs collaboration with clients and suppliers and currently includes more than 900 minority- and women-owned vendors. By successfully utilizing these mutually beneficial business relationships, we help meet the diversity goals that we have set for Omnicom as well as those of our clients.

The proposal requests release of information that would not be informative and could harm the Company

     The shareholder proposal requests public disclosure of the data contained in Form EEO-1, which Omnicom and other private employers are required to prepare and file annually on a confidential basis with the Equal Employment Opportunity Commission (“EEOC”). Form EEO-1 requires us to categorize our workforce by gender and race according to certain EEOC-mandated job categories that do not account for any company or industry specific factors. It is designed to yield generalized data across all categories of private employers rather than information specific to Omnicom or comparable companies in the advertising industry. For these reasons, EEO-1 data is neither informative nor is it a reliable measure of our commitment to equal opportunity

51

employment. We do not believe that disclosing it will meaningfully further the goal of workplace diversity. To the contrary, this information, which is susceptible to misinterpretation, could be manipulated by those with interests adverse to Omnicom’s and harm the Company.

The proposal is unnecessary because the Company already publishes similar information regarding diversity

     The Company already shares information regarding our diversity philosophy and programs in our annual Citizenship & Sustainability Report, which is currently available to the public on our global citizenship and sustainability website, http://csr.omnicomgroup.com. This detailed report, in addition to the video testimonials that accompany it on the website, is a superior medium through which we can explain our various initiatives and highlight the contributions that all of our employees make to our diverse corporate culture. The time and expense involved in producing the EEO-1 information requested by the shareholder proposal in a format suitable for disclosure neither furthers our equal employment efforts, nor is it a prudent use of our resources.

     For the above reasons, the Board of Directors does not believe that it is in the best interests of Omnicom or its shareholders to adopt this proposal. Doing so is unnecessary in light of Omnicom’s existing and active commitment to diversity and not in the best interests of our shareholders.

     For these reasons, the Board of Directors UNANIMOUSLY urges shareholders to vote AGAINST the shareholder proposal regarding annual disclosure of EEO-1 data.

     Approval of this proposal requires the favorable vote of the holders of a majority of the shares voting on the proposal. Abstentions and broker non-votes will have no effect on the outcome of this proposal.

52

INFORMATION ABOUT VOTING AND THE MEETING

Quorum; Required Vote; Effect of an Abstention and Broker Non-Votes

     More than 50% of the shares entitled to vote will constitute a quorum for the transaction of business at the 2012 Annual Meeting. Abstentions and broker non-votes will be counted for purposes of determining whether a quorum exists. Broker non-votes are proxies returned by brokers or other nominees who do not vote on a particular item because they did not receive instruction from the beneficial owner and were not permitted to exercise discretionary voting authority. If a quorum is not present, the shareholders who are present or represented may adjourn the meeting until a quorum exists. The time and place of the adjourned meeting will be announced at the time the adjournment is taken, and no other notice need be given. We will, however, publish a press release if the meeting is adjourned to another date. An adjournment will have no effect on business that may have already been conducted at the meeting.

     In order to obtain approval of the election of any nominee as a director, assuming a quorum exists, a director nominee must receive a majority of the votes cast with respect to such nominee, meaning the number of shares voted “for” a director nominee must exceed the number of votes cast “against” that nominee. In order to ratify the appointment of KPMG LLP as our independent auditors, assuming a quorum exists, the affirmative vote of the holders of a majority of the shares represented at the meeting and actually voted is required. Abstentions and broker non-votes will not be considered as votes cast in favor or against proposals that require the affirmative vote of the holders of a majority of the votes cast, which includes items 3, 4 and 5 and thus will have no effect on the outcome of those proposals.

Voting

     You can vote your shares by proxy card, through the Internet, by telephone or in person. We have adopted the Internet and telephone voting procedures to authenticate shareholders’ identities, to allow shareholders to provide their voting instructions and to confirm that their instructions have been recorded properly. By submitting your proxy through the Internet, by telephone or by using the proxy card, you will authorize two of our officers or their designees to represent you and vote your shares at the meeting in accordance with your instructions or, if no instructions are given, your shares will be voted as described below in the section entitled “‘Default’ Voting.”

     Fidelity Management Trust Company, as trustee under our retirement savings plan, and Computershare Trust Company, Inc., as administrator of our ESPP, will vote common stock held in the plans as indicated by participants in whose accounts the shares are held, whether or not vested, on their proxies. Please note that your shares held in either plan will be voted as you instruct if your proxy card, telephone or Internet voting instructions are received on or before 11:59 p.m. Eastern Daylight Time on Thursday, May 17, 2012. In accordance with the terms of the retirement savings plan, Fidelity Management Trust Company will vote all shares for which it does not receive voting instructions by the deadline provided above in the same proportion on each issue as it votes the shares for which it does receive instructions. In accordance with the terms of the ESPP, Computershare Trust Company, Inc. will not vote shares for which it does not receive voting instructions by the deadline provided above.

Voting by Street Name Holders

     If you are the beneficial owner of shares held in “street name” by a broker, bank or other nominee, the broker, bank or other nominee, as the record holder of the shares, is required to vote those shares according to your instructions. Your broker, bank or other nominee should have sent you a voting instruction card for you to use in directing it on how to vote your shares.

     Under existing rules, if your broker holds your shares in its name and you have not given voting instructions, your broker nonetheless has the discretion to authorize the designated proxies to act, except on certain matters. As such, they could vote in respect of the ratification of the appointment of KPMG LLP as our independent auditors, but not on the election of directors, the amendment and restatement of the Company’s By-laws to provide that holders of at least 25% of the combined voting power of the Company’s outstanding capital stock may request a special meeting of shareholders, the advisory resolution on the Company’s executive compensation or the shareholder proposal regarding annual disclosure of EEO-1 data.

53

“Default” Voting

     If you submit a proxy, whether through the Internet, by telephone or by using the proxy card, but do not indicate any voting instructions, your shares will be voted FOR the election of all nominees for director, FOR the ratification of the appointment of KPMG LLP, FOR the amendment and restatement of the Company’s By-laws to provide that holders of at least 25% of the combined voting power of the Company’s outstanding capital stock may request a special meeting of shareholders, FOR the advisory resolution on the Company’s executive compensation and AGAINST the shareholder proposal regarding annual disclosure of EEO-1 data. If any other business properly comes before the shareholders for a vote at the meeting, your shares will be voted according to the discretion of the holders of the proxy. They may also vote your shares to adjourn the meeting and will be authorized to vote your shares at any adjournments or postponements of the meeting.

Right to Revoke

     If you submit your proxy, you may change your voting instructions at any time prior to the vote at the 2012 Annual Meeting. For shares held directly in your name, you may change your vote by granting a new proxy, through the Internet, by telephone or in writing, which bears a later date (thereby automatically revoking the earlier proxy) or by attending the 2012 Annual Meeting and voting in person. For shares beneficially owned by you, but held in “street name” by a broker, bank or other nominee, please refer to the information forwarded to you by your broker, bank or other nominee for instructions on revoking or changing your proxy.

Tabulation of Votes

     Wells Fargo Bank, N.A. will act as inspectors at the 2012 Annual Meeting. They will determine the presence of a quorum and will tabulate and certify the votes.

54

ADDITIONAL INFORMATION

Section 16(a) Beneficial Ownership Reporting Compliance

     Section 16(a) of the Securities Exchange Act of 1934, as amended, requires our directors and executive officers, and persons who own more than 10% of our common stock, to file reports of ownership and changes in ownership of our common stock with the SEC. Purchases and sales of our common stock by such persons are published on our website at http://www.omnicomgroup.com.

     Based solely upon a review of the copies of such reports filed with the SEC, and on written representations from our reporting persons, we believe that all Section 16(a) filing requirements applicable to our executive officers, directors and persons who own more than 10% of our common stock were complied with during 2011, with the following exception. Last year, the Form 3 report deadline was missed for Mary C. Choksi due to administrative oversight.

Transactions with Related Persons

     We review all relationships and transactions between Omnicom or its subsidiaries and related persons to determine whether such persons have a direct or indirect material interest. Related persons include any director, nominee for director, officer or their immediate family members. Although we do not have a written policy governing such transactions, Omnicom’s legal staff is primarily responsible for the development and implementation of processes and controls to obtain information from the directors and officers with respect to related person transactions and for then determining, based on the facts and circumstances, whether the company or a related person has a direct or indirect material interest in the transaction. As part of this process, and pursuant to our Audit Committee’s charter, the Audit Committee reviews our policies and procedures with respect to related person transactions. These policies and procedures have been communicated to, and are periodically reviewed with, our directors and executive officers, and the Audit Committee documents in its minutes any actions that it takes with respect to such matters. Under SEC rules, transactions that are determined to be directly or indirectly material to Omnicom, its subsidiaries or a related person are required to be disclosed in Omnicom’s Proxy Statement. In the course of reviewing a related party transaction, Omnicom considers (a) the nature of the related person’s interest in the transaction, (b) the material terms of the transaction, (c) the importance of the transaction to the related person and Omnicom or its subsidiaries, (d) whether the transaction would impair the judgment of a director or officer to act in the best interest of Omnicom, and (e) any other matters deemed appropriate.

     Based on the information available to us and provided to us by our directors and officers, we do not believe that there were any such material transactions in effect since January 1, 2011, or any such material transactions proposed to be entered into during 2012, with the following exception. Mr. Wren’s brother, Christopher Wren, is employed as the Director of Financial Systems for Rapp, a subsidiary of Omnicom. In 2011, his total compensation was $165,040, including salary, bonus and other benefits.

Expense of Solicitation

     We will bear all costs of this proxy solicitation. Proxies may be solicited by mail, in person, by telephone or by facsimile or electronic transmission by our officers, directors, and regular employees. We may reimburse brokerage firms, banks, custodians, nominees and fiduciaries for their expenses to forward proxy materials to beneficial owners. We have retained Morrow & Co., LLC, 470 West Avenue, Stamford, CT 06902 to assist in the solicitation of proxies. For these services, we will pay Morrow & Co. a fee of approximately $9,500 and reimburse it for certain out-of-pocket disbursements and expenses.

Incorporation by Reference

     To the extent that this Proxy Statement is incorporated by reference into any other filing by Omnicom under the Securities Act of 1933 or the Securities Exchange Act of 1934, as amended, the sections of this Proxy Statement entitled “Executive Compensation: Compensation Committee Report,” “Audit Related Matters: Audit Committee Report” (to the extent permitted by the rules of the SEC) will not be deemed incorporated, unless specifically provided otherwise in such filing.

     If you are the beneficial owner of shares of our common stock held in “street name” by a broker, bank or other nominee, your broker, bank or other nominee may only deliver one copy of this Proxy Statement and our 2011 Annual Report to multiple shareholders who share an address unless that broker, bank or other nominee has received contrary instructions from one or more of the shareholders at a shared address. We will deliver promptly, upon written or oral request, a separate copy of this Proxy Statement and our 2011 Annual Report to a shareholder at a shared address to which a single copy of the documents was delivered. A shareholder who wishes to receive a separate copy of the Proxy Statement and Annual Report, now or in the future, should submit this request by writing to: Omnicom Group Inc., 437 Madison Avenue, New York, New York 10022, Attn: Corporate Secretary or calling our Corporate Secretary at (212) 415-3600. Beneficial owners sharing an address who are receiving multiple copies of Proxy Statements and Annual Reports and who wish to receive a single copy of such materials in the future will need to contact their broker, bank or other nominee to request that only a single copy of each document be mailed to all shareholders at the shared address in the future.

SHAREHOLDER PROPOSALS FOR THE 2013 ANNUAL MEETING

     Any shareholder who wishes to present a proposal for inclusion in next year’s Proxy Statement and form of proxy must deliver the proposal to our principal executive offices no later than the close of business on December 14, 2012. Proposals should be addressed to: Omnicom Group Inc., 437 Madison Avenue, New York, New York 10022, Attn: Corporate Secretary.

     Our By-laws require that written notice of the proposal be provided to our Corporate Secretary no less than 60 days prior to the date set for the meeting, which was March 23, 2012 for the 2012 Annual Meeting. In order for a nomination for director or proposal to be considered, the notice must include, as to each nominee (if applicable) and the submitting shareholder, the information as to such nominee and shareholder that would be required to be included in a proxy statement under the proxy rules of the SEC if such shareholder were to solicit proxies from all shareholders of Omnicom for the election of such nominee as a director or approval of such proposal and such solicitation were one to which Rules 14a-3 to 14a-12 under the Securities Exchange Act of 1934, as amended, apply. A copy of the applicable By-law provisions may be obtained, without charge, upon written request addressed to: Omnicom Group Inc., 437 Madison Avenue, New York, New York 10022, Attn: Corporate Secretary. As the rules of the SEC make clear, simply submitting a proposal does not guarantee its inclusion.
