                                PROXY STATEMENT


      Our Board of Directors is using this proxy statement to solicit proxies
for our 2004 annual shareholders meeting. This proxy statement and the related
proxy card are being mailed on or about April 23, 2004.

      Each shareholder is entitled to one vote for each share held on April 9,
2004, which is the record date for the meeting. You can vote your shares:

      o     by returning the enclosed proxy card;

      o     through the internet at the website shown on the proxy card;

      o     by telephone using the toll-free number shown on the proxy card; or

      Additional information about the meeting appears at pages 17 and 18.

                              CORPORATE GOVERNANCE

Board Composition; Communications

      Our Board currently consists of nine independent directors, our
non-executive chairman (Bruce Crawford) and our CEO (John Wren). Due to the
declassification of our Board last year, each director stands for election
annually. Biographical information and information about the committees on which
our directors serve is set forth in "Election of Directors" at pages 5 to 7.

      Under our corporate governance guidelines, the Board determines whether
each outside director has any business, family or other relationship different
from or in addition to the interests of shareholders or the other directors
generally that could reasonably be expected to interfere with the director's
ability to independently make director decisions. None of our outside directors
has a relationship with Omnicom other than as director and no outside director
has received any compensation from us other than for his or her service as a
director. Our Board has determined, therefore, that all of our outside directors
are independent under existing applicable requirements, as well as our own
corporate governance guidelines.

      The functions of our Board chairman and CEO are presently separated. For
this and other reasons, the Board has not thought it necessary to formally
designate a particular independent director as a lead director. As a matter of
policy, the independent directors regularly meet by themselves. The Chairman of
the Board's Governance Committee presides at these sessions.

      Interested parties, including shareholders, may communicate (if they wish,
on a confidential, anonymous basis) directly with the independent directors as a
group, with the Board as a whole or with any individual director by writing to
our corporate secretary at the address above. Communications that are intended
specifically for the non-management directors or any individual director should
clearly state that the independent directors or the named individual director is
the intended recipient of such communication and such communications should be
marked "Confidential".


                                       3


      The Board encourages stock ownership by directors and senior managers. As
described below, a majority of each director's annual retainer is paid in stock
and directors are permitted to elect to receive an additional portion of their
cash compensation in common shares. For information about stock ownership by our
directors and executive officers, see "Stock Ownership" at page 13. The Board
has recently adopted stock ownership guidelines for our directors and is in the
process of considering stock ownership guidelines for our executive officers.
The director guidelines provide, in general, that our directors must own Omnicom
stock equal to or greater than five times their annual cash retainer within five
years of adoption of the guidelines or within five years of their joining the
Board, whichever is later.

Board Operations

      Our Board met five times last year.

      The Board's policy is generally to conduct specific oversight tasks
through committees, with the objective of freeing the Board as a whole to focus
on strategic matters as well as particular tasks which by law or custom require
the attention of the full Board. Our Board has established four standing
committees, functioning in the following areas:

      o     audit and financial reporting

      o     management/compensation

      o     corporate governance

      o     finance and acquisitions/divestitures

      Each of the committees operates under a written charter recommended by the
Governance Committee and approved by the Board and the Board operates pursuant
to our corporate governance guidelines. Each Board committee is authorized to
retain its own outside advisors. All members of our Audit, Compensation and
Governance Committees are required to be independent directors. Our corporate
governance guidelines and committee charters are posted on our website at
www.omnicomgroup.com.

      Audit Committee: The Audit Committee's purpose is to assist the Board in
carrying out its oversight responsibilities relating to financial reporting. In
this regard, the committee assists Board oversight of (1) the integrity of our
financial statements, (2) compliance with legal and regulatory requirements, (3)
the qualifications and independence of our independent auditor, and (4) the
performance of our internal audit function and independent auditor. Among other
responsibilities, the Audit Committee has the power to retain or dismiss, and to
approve the compensation of, our outside audit firm. The members of our Audit
Committee are Messrs. Murphy (Committee Chair), Clark, Cook and Henning. The
Board has determined that each of the members of our Audit Committee is an audit
committee financial expert within the meaning of applicable SEC regulations. All
of the members of our Audit Committee are independent and financially literate
within the meaning of applicable stock exchange requirements.

      The Audit Committee met 12 times last year.

      A copy of the Audit Committee's annual report is included at page 14; the
Audit Committee's charter is available on our website (www.omnicomgroup.com) and
is included as Appendix A to this proxy statement.

      Compensation Committee: The Compensation Committee's purpose is to assist
the Board in carrying out its oversight responsibilities relating to
compensation matters, to prepare a report on executive compensation for
inclusion in our annual proxy statement and to serve as the Board committee
authorized to administer and approve awards under our equity and other
compensation plans. The members of our Compensation Committee are Messrs. Roubos
(Committee Chair) and Coleman and Ms. Denison and Ms. Rice. All of the members
of our Compensation Committee are independent.

      The Compensation Committee met five times last year.

      A copy of the Compensation Committee's annual report is included at pages
9 to 11; the Compensation Committee's Charter is available on our website
(www.omnicomgroup.com).


                                       2


      Governance Committee: The Governance Committee's purpose is to assist the
Board in carrying out its oversight responsibilities relating to corporate
governance matters, including in respect of the composition of the Board. As
part of its responsibilities, the committee considers and makes recommendations
to the full Board with respect to the following matters:

      o     nominees for election to the Board and committees it establishes
            from time to time and criteria therefor;

      o     the functions of the Board committees;

      o     standards and procedures for review of the Board's performance;

      o     the company's 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;

      o     management succession;

      o     the code of business conduct applicable to our directors, officers
            and employees; and

      o     the Governance Committee's performance of its own responsibilities.

      The members of our Governance Committee are Messrs. Purcell (Committee
Chair), Clark, Coleman and Murphy, and Ms. Denison and Ms. Rice. All of the
members of our Governance Committee are independent.

      Nominations for director 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
meeting. Under federal law, shareholders desiring to submit a proposal for
inclusion in our proxy materials for our 2005 annual shareholders meeting are
required to do so by December 24, 2004. See "Additional Information" at pages 17
and 18 for additional information on this topic. You can obtain a copy of the
full text of the by-law provision noted above by writing to the corporate
Secretary at our address on page 1 of this proxy statement. Our by-laws have
also been filed with the SEC.

      The Board has not thought it necessary at this time to adopt a formal
policy relating to the consideration of director candidates recommended by our
shareholders. We did not receive any recommended nominees from shareholders this
year. The Governance Committee will consider any future director candidates
recommended by shareholders that are properly submitted. The Governance
Committee will also consider whether a formal policy relating to consideration
of director nominees by shareholders is desirable.

      Our Board seeks to assure that it is composed of individuals with
substantial experience and judgment from diverse backgrounds but, except for the
requirement that a substantial majority be independent, non-management
directors, we do not have rigid director qualification requirements. However,
our Governance Committee will consider the following qualifications and skills
of director nominees:

      o     their independence;

      o     their background and experience in relation to other members of the
            Board; and

      o     their commitment to the time required to discharge their duties.

      The Governance Committee reviews the composition of the Board not less
frequently than 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 to identify director candidates.
The Committee has the power to engage third parties to assist in identifying and
evaluating potential nominees.

      The Governance Committee met four times last year.

      A copy of the Governance Committee's charter is available on our website
(www.omnicomgroup.com).

      Finance Committee: The Finance Committee's purpose is to assist the Board
in carrying out its oversight responsibilities relating to financial matters
affecting the company, including in respect of acquisitions, divestitures and
financings.


                                       3


      The Finance Committee met six times last year.

      A copy of the Finance Committee's Charter is available on our website
(www.omnicomgroup.com).

Director Attendance

      Our incumbent directors attended all or substantially all of the meetings
of the Board and committees of which they were members last year. Although we do
not have a formal policy regarding attendance by members of our Board at our
annual meeting, we do encourage our directors to attend and a substantial
majority of our directors have attended our annual shareholder meetings. In
2003, all of our directors attended the annual meeting and it is expected that
all will attend this year absent unforeseen events.

Director Compensation

      Directors who are not current or former employees of Omnicom or its
subsidiaries are paid:

      o     250 shares of restricted stock each year;

      o     an annual retainer of $60,000; and

      o     $2,000 for attendance at a Board or committee meeting in person,
            $1,000 for participation by telephone or video conference at any
            regularly scheduled meeting and $2,000 for participation by
            telephone or video conference at any special meeting.

      The restricted stock is awarded on the first business day after each
annual shareholder meeting and vests over two years. The Chair of our Audit
Committee receives an additional fee of $10,000 each year. We do not have a
retirement plan for directors.

      If our director equity plan is approved by shareholders at the meeting, in
addition to the annual retainer and meeting fees, directors will receive common
shares each year equal in value at the time of award to $70,000 and will no
longer receive the annual grant of restricted stock. Further, our existing
director compensation arrangement provides, and the new director equity plan, if
approved, will provide that each director may elect to receive all or a portion
of his or her cash director fees for the following year's service in common
shares. 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 common shares delivered or
credited to a director's account will be based on the fair market value of our
common shares on the first trading day immediately preceding the date the fees
would have been paid to the director.

Ethical Business Conduct

      We have a code of conduct in place designed to assure that our business is
carried out in an honest and ethical way. The code of conduct requires that our
employees avoid conflicts of interest, comply with all laws and other legal
requirements and otherwise act with integrity. In addition, we have rules
regarding ethical action and integrity relating to financial matters applicable
to our financial and accounting officers. Our code of conduct and these rules
are posted on our website (www.omnicomgroup.com), and are also available in
print to any shareholder that requests them. We do not intend to waive any
provision of our code of conduct and will not waive the rules applicable to our
financial and accounting officers. If, however, special circumstances ever
warrant a waiver of our code of conduct, we would disclose the waiver as
required by law.

      We also have procedures to receive, retain and treat complaints received
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 rules applicable to our financial and
accounting officers. The procedures are posted on our website and the websites
of our various global networks.

Relationship with Independent Accountants and Related Matters

      The Board's Audit Committee reappointed KPMG, LLP as our independent
public accounting firm to audit our financial statements for 2004.


                                       4


      In deciding to reappoint KPMG to be our auditor for 2004, the Audit
Committee considered KPMG's provision of services last year to assure that they
were compatible with maintaining KPMG's independence. All fees paid to KPMG last
year are described at page 15. The Committee determined that these fees were
compatible with the independence of KPMG as our independent auditor. We adopted
a policy that prohibits use of our independent auditors for any financial
information systems design and implementation services, and requires that all
non-audit services be approved by our Audit Committee.

      In accordance with applicable legal requirements, the lead partner on our
audit engagement will be required to change every five years, and we have
adopted a policy prohibiting hiring members of our outside audit firm who have
management roles on the engagement into our financial or accounting groups
within a year after they leave employment with the firm.

      Information relating to our relationship with our outside auditors appears
under "Audit Committee Report" at page 14.

             SECTION 16(A) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE

      Section 16(a) of the Exchange Act requires our directors and executive
officers and persons who own 10% or more of our common stock to file reports of
ownership and changes in ownership of Omnicom common shares with the Securities
and Exchange Commission. The SEC has established certain due dates for these
reports. We are not aware of any instances of noncompliance, or late compliance,
with Section 16(a) filing requirements by our directors, executive officers or
10% or greater shareholders during 2003, except that one Form 3 of Kenneth R.
Kaess, Jr., who heads our DDB branch, was filed late due to administrative
oversight.
                              CERTAIN TRANSACTIONS

      One of our executive officers, Jean-Marie Dru, held preferred stock in MNH
Holding Inc., a company in which we own all of the common equity. On November
24, 2003, we bought from Mr. Dru the preferred stock he held in MNH Holding Inc.
for $5.0 million. The value of the preferred stock was determined based upon a
multiple of MNH Holding Inc.'s operating income, which was agreed upon prior to
the time that Mr. Dru became an executive officer of Omnicom. Mr. Dru also had
an interest bearing note outstanding during the fiscal year ended December 31,
2003, which was issued on April 1, 2000, prior to Mr. Dru's becoming an
executive officer. The interest rate on the loan was 7% during the fiscal year.
The highest aggregate outstanding balance during the fiscal year was not more
than $1.3 million. The loan was repaid in full on March 1, 2004.

                              ELECTION OF DIRECTORS

      The current 11 members of the Board have been nominated to continue to
serve as directors for another year.

The Board recommends that shareholders vote FOR all nominees.

      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 plurality of
the votes cast. That means the nominees will be elected if they receive more
affirmative votes than any other nominees. Our form of proxy permits you to
withhold your vote for particular nominees. However, shares represented by
proxies so designated will count as being present for purposes of determining a
quorum and will not affect whether a given nominee is elected because directors
are elected by a plurality of the shares voted at a meeting at which a quorum is
present. Such proxies may also be voted on other matters, if any, that may be
properly presented at the meeting.

      Set forth below is biographical and other information about our nominees
for election as director.

Stock Options

      Option Grants in Last Fiscal Year: No stock options were granted to the
named executive officers in 2003.

      Aggregated Option Exercises Last Year and Year-End Option Values: The
following table provides information about option exercises by the named
executive officers in 2003, and the value of their unexercised options at the
end of 2003. The value realized was calculated by subtracting the exercise price
from the fair market value of our common stock on the exercise date. The value
of unexercised in-the-money options at December 31, 2003 was calculated by
subtracting the exercise price of in-the-money options from the closing sales
price ($87.33) of our common stock on December 31, 2003.

Compensation Committee Report

      The members of our Committee are Gary L. Roubos, Committee Chair, Leonard
S. Coleman, Jr., Susan S. Denison and Linda Johnson Rice. Each of us is an
independent director.

      Omnicom's executive compensation structures for senior management have
been designed to attract, retain and properly motivate qualified managers using
a combination of three principal elements: base salary, performance-based cash
bonuses and long-term equity-linked awards. Historically, the fixed portion of
compensation has been substantially less than the variable portion to provide
management incentives to achieve performance goals.

      We determine the compensation of the chief executive officer and named
executive officers subject, in the CEO's case, to the approval of the full
Board. We consider the factors described below and the recommendations of the
CEO in determining the compensation of the named executive officers. The CEO
determines the salaries of executives who are not named executive officers.

      We periodically engage compensation consultants to assist us generally in
overseeing Omnicom's compensation programs and in determining appropriate
compensation levels and structures for executive officers.

      Base Salary: Adjustments in base salary for executive officers are
discretionary and generally are considered every 18 months. In determining base
salary and adjustments to base salary, we consider:

      o     the executive's level of responsibility;

      o     Omnicom's profitability and the profitability of the business unit
            with which the executive is associated; and

      o     information and our knowledge of executive compensation practices of
            other publicly traded companies of similar size, geographic reach
            and financial characteristics.

      Omnicom's profitability is determined by reference to its earnings per
share, and profitability of a business unit is determined by reference to its
operating profit.

      Incentive Cash Bonuses: The annual cash bonus typically represents a
substantial portion of the cash compensation of executive officers. Omnicom
intends that the annual cash bonus serve as an incentive to improve annual
profitability. We administer incentive bonuses for all executive officers.


                                       9



      Prior to or shortly after the beginning of the year, we identify the
executive officers who will participate in Omnicom's annual bonus plan and their
incentive levels. We normally establish specific performance goals based on
business criteria and assign weights to the goals. In general, performance goals
are based on one or more of the following criteria: earnings per share, net
income, operating margin, return on equity, stockholder total return, revenue
and cash flow.

      At the end of the year, we review the performance of each participant
against his or her performance goals. Awards are paid only after we have
determined that the performance goals have been attained. We consider the
recommendations of the CEO as to the named executive officers other than the
CEO, and we retain the discretion to reduce, but not increase, the amount of an
award otherwise payable to a participant despite the attainment of previously
established performance goals.

      In 2003, Omnicom exceeded threshold levels of performance, and the
executive officers were entitled to their targeted cash bonuses. Senior
management, including the named executive officers and other executive officers,
however, elected to receive reduced bonuses to assure that lower-level employees
receive substantial incentive compensation in recognition of their excellent
performance in 2003. For the same reason, senior management elected to receive
no or substantially reduced bonuses for the prior year, even though performance
criteria were satisfied.

      Stock-Based Incentive Awards: We determined the restricted stock award
grants for the named executive officers. Restricted stock award grants for
executive officers who are not named executive officers are recommended by the
CEO and determined by us in a discretionary manner.

      We grant restricted stock awards annually to a relatively broad group of
key executives, based upon the executive's level of responsibility and our
judgment of the executive's contribution to Omnicom's performance.

      Stock options have historically been granted annually to selected
executives, based upon the revenue growth and profitability of Omnicom and the
business unit with which the executive was associated. Beginning in 2003, we
instructed Omnicom to consider and utilize alternative forms of incentive
compensation. Stock options are granted with an exercise price equal to the
market price of Omnicom's stock on the day of grant and generally vest over a
period of three years. However, we made stock option grants in one year that
vested over a period of six years, subject to acceleration in certain events
including the attainment of certain share price thresholds.

      We are currently in the process of considering the establishment of stock
ownership guidelines for executive officers.

      Performance Share Units: In prior years, we have approved awards to
certain executive officers under which they have the right to earn performance
share units. Performance share units entitle the holder to payouts of cash
and/or common stock, as determined by our Committee, up to a maximum amount,
based on the value of one share of common stock on the payout date for each
performance share unit. We retain the overall discretion to reduce any
performance compensation and performance share units that the holder would
otherwise be entitled to receive.

      Our Committee awards performance share units based on our review of
Omnicom's earnings per share growth over a three-year period. If the executive
officer is affiliated with one of Omnicom's subsidiaries, we evaluate the
executive using a formula which considers both Omnicom's earnings per share
growth over a three-year period and the three-year net profit growth of that
subsidiary. No performance share units for the performance period of 2001 to
2003 were paid out because the executive officers eligible to receive these
awards elected not to receive them, even though the specified targets were met.

      CEO Compensation: After receiving no salary increases for six years, we
recommended an increase in Mr. Wren's salary for 2003 to $1,000,000 per year, up
from $875,000 per year. At his election, Mr. Wren's annual cash bonus was
reduced to $1,100,000 for 2003 even though he was entitled to a higher amount
under the criteria we had established at the beginning of the year.

      Mr. Wren received no long-term incentive compensation during 2003.


                                       10


      Internal Revenue Code Section 162(m): Section 162(m) places a limit of $1
million on the deductibility of compensation Omnicom pays to its Chief Executive
Officer and certain other executive officers during each year unless the
compensation qualifies as "performance-based compensation." We intend 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.

Salary Continuation Agreements

      We have agreed to make annual payments to each of the named executive
officers for up to 10 years after termination of full time employment, unless
termination is for "cause," in consideration for their agreements not to compete
and to consult during the service period. "Cause" is generally defined for this
purpose as willful malfeasance, such as breach of trust, fraud or dishonesty. If
a covered executive dies before expiration of the applicable payment period, his
beneficiary is entitled to 75% of the executive's payment for the remainder of
that period. The payments are equal to a percentage of the covered executive's
salary and are subject to reduction in certain circumstances. The salary
percentages are equal to 100% for Mr. Rosenshine and 50% for the other named
executive officers. The payment periods are based on age and service and are
currently, 10 years for Messrs. Rosenshine and Mead and 9 years for Messrs.
Wren, Harrison and Kaess.

                            EQUITY COMPENSATION PLANS

      Our principal equity plan for employees is our equity incentive plan,
which was approved by shareholders last year and replaced all prior employee
equity incentive plans. As a result, no new awards may be made under prior plans
except for prior awards that are forfeited or canceled. We also have a
restricted stock plan for non-employee directors and a tax-qualified employee
stock purchase plan available to substantially all employees.

      Our equity compensation plans have been approved by shareholders, except
for our current restricted stock plan for non-employee directors, which we
adopted in 2000. As of March 31, 2004, 16,846 shares remained available for
issuance under this plan; if the proposed director equity plan is approved by
shareholders at the annual shareholders meeting, no further shares will be
issued under this plan. The following table provides information about our
equity compensation plans as of December 31, 2003. The table does not reflect
the shares that will be authorized under the proposed director equity plan if it
is approved by shareholders at the annual meeting.

      participate. It also includes 407,620 shares that can be issued under
      prior plans as a result of forfeitures. Additional shares may become
      available in the future if awards under the prior plans are forfeited, but
      that number is not determinable. As of December 31, 2003, the maximum
      number of shares that may be issued under our equity incentive plan as
      restricted stock or other non-option awards is 3.4 million shares.

      director equity plan is approved at the annual meeting, this plan will be
      terminated.


                                PERFORMANCE GRAPH

      The graph below compares cumulative total return on our common stock
during the last five years with the Standard & Poor's 500 Composite Index and a
peer group of publicly held corporate communications and marketing holding
companies. The peer group consists of Grey Advertising Inc., The Interpublic
Group of Companies, Inc., WPP Group plc and Publicis Groupe SA. Cordiant
Communications Group, which was included in the peer group for prior years, is
no longer included. Cordiant was acquired by WPP Group. As a result, the graph
has been restated for all years without including Cordiant. The graph shows the
value at the end of each year of each $100 invested in our common stock, the S&P
500 Index and the peer group. The graph assumes the reinvestment of dividends.

      Returns depicted in the graph are not indicative of future performance.

             RATIFICATION OF THE APPOINTMENT OF INDEPENDENT AUDITOR

      In accordance with the Audit Committee's charter, the Audit Committee has
appointed KPMG LLP as our independent auditor for the fiscal year ending
December 31, 2004. The Board recommends, and unless otherwise directed, the
designated persons named in the enclosed form of proxy will vote for,
ratification of such appointment of KPMG. KPMG has been our independent auditor
since June 2002.

      Representatives of KPMG are expected to be present at the 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 auditor. However, the Audit Committee will
consider the results of the vote, particularly a failure to ratify selection of
the independent auditor, in selecting the independent auditor in the future.

      The Board recommends that shareholders vote FOR ratification of the
appointment of KPMG as our independent auditor. Approval of this proposal
requires the favorable vote of the holders of a majority of the shares voting on
the proposal.

               ADDITIONAL MATTERS PERTAINING TO OUR AUDIT FUNCTION

Audit Committee Report

      The members of our Committee are John R. Murphy, Committee Chair, Robert
Charles Clark, Errol M. Cook and Michael A. Henning. Each of us is independent
as defined in the New York Stock Exchange's listing standards, which provide,
among other things, that directors may have no material relationship with
Omnicom. Omnicom's Board of Directors has adopted a written Audit Committee
Charter, a copy of which is included as Appendix A to this proxy statement.

      We have reviewed and discussed with management Omnicom's audited 2003
financial statements as of December 31, 2003.

      We have discussed with KPMG the matters required to be discussed by
Statement on Auditing Standards No. 61, "Communication with Audit Committees,"
as amended, as issued by the Auditing Standards Board of the American Institute
of Certified Public Accountants.

      We have received and reviewed the written disclosures and the letter from
KPMG required by Independence Standard No. 1, as adopted by the Independence
Standards Board, and have discussed with KPMG its independence.

      Specific information about fees paid to KPMG, and recent developments
affecting the firm, are contained in the next section of this proxy statement.

      Based on the review and discussions referred to above, we have recommended
to the Board that the audited financial statements for the year ended December
31, 2003 be included in the 2003 annual report.

Independent Auditors

      On June 12, 2002, we dismissed Arthur Andersen LLP and engaged KPMG as our
new independent auditors for the fiscal years ending on December 31, 2002 and
thereafter. These actions were approved by the Board based on the
recommendations of the Audit Committee. During the years ended December 31, 2000
and 2001 and through the date of the Board's decision, we did not consult KPMG
regarding any of the matters or events set forth in Item 304(a)(2)(i) or (ii) of
Regulation S-K. We continued to use Arthur Andersen to perform services as our
predecessor auditor with respect to financial statements prior to June 12, 2002.

      The report of Arthur Andersen on our financial statements for the fiscal
years ended December 31, 2000 and December 31, 2001 did not contain an adverse
opinion, disclaimer of opinion or qualification or modification as to
uncertainty, audit scope or accounting principles. During the fiscal years ended
December 31, 2000 and December 31, 2001 and the subsequent interim period
through June 12, 2002, there were no disagreements with Arthur Andersen on any
matters of accounting principles or practices, financial statement disclosure or
auditing scope or procedures. During the fiscal years ended December 31, 2000
and December 31, 2001, and during the subsequent interim period through June 12,
2002, there were no reportable events (as defined in Item 304(a)(1)(v) of
Regulation S-K).

      We paid or will pay the following fees to KPMG and affiliates for services
rendered during the last two years:

                                                      2003            2002

      "Audit fees" are fees for professional services for the audit or review of
our consolidated financial statements or for services that are normally provided
by an independent auditor in connection with statutory and regulatory filings or
engagements; "Audit-related fees" are billed by KPMG for assurance and related
services that are reasonably related to the performance of the audit or review
of our consolidated financial statements; "Tax fees" are fees for tax
compliance, tax advice and tax planning; and "All other fees" would be fees
billed by KPMG to Omnicom for any services not included in the first three
categories.

      The Audit Committee considered all these services in connection with
KPMG's audit or review of our 2003 financial statements and concluded that they
were compatible with maintaining KPMG's independence.

                      APPROVAL OF THE DIRECTOR EQUITY PLAN

      At the annual meeting, shareholders will be asked to approve the adoption
of our director equity plan. The purposes of the plan are to provide for the
award of stock on an annual basis to directors of Omnicom who are not employees
or former employees and to otherwise allow these directors to participate in the
ownership of our common shares. The Board adopted the plan, subject to
shareholder approval. If the plan is approved by shareholders, no additional
restricted shares will be granted under our restricted stock plan for
non-employee directors.

Plan Summary

      The following is a summary of the material provisions of the plan. The
summary is qualified in its entirety by reference to the plan, a copy of which
is attached to this proxy statement as Appendix B.

      Awards Authorized

      The plan will be administered by the Board's Compensation Committee.

      On a quarterly basis, each eligible director will receive a number of
common shares equal to $17,500 (or such other amount as determined by the Board
from time to time) divided by the fair market value (determined by reference to
reported closing sales price) of one common share on the first trading day
immediately preceding


                                       15


the date of the award for services to be performed in the following quarter. The
maximum number of common shares that may be issued or credited to directors'
accounts pursuant to the foregoing sentence is 50,000 shares, subject to
adjustment to reflect any change in the Company's outstanding shares by reason
of a recapitalization, reclassification, stock split-up or combination of
shares. The first quarterly payment will be paid on the first business day
following our annual meeting.

      Each director eligible to participate in the plan may also elect to have
his or her cash compensation (including annual cash retainer and/or meeting
fees) payable in common shares. For the portion of compensation received in
common shares, the number of shares that will be issued will equal the cash
amount that would have been paid divided by the fair market value of one common
share on the first trading day immediately preceding the date on which such cash
amount would have been paid.

      A director may further elect to have the annual amount of $70,000 worth
(or such other amount as determined by the Board) of common shares plus any
other compensation that the director elects to receive in common shares paid in
the form of deferred shares, which will be credited to a bookkeeping account in
the name of the director. If a director elects to receive deferred shares, there
will be credited to his or her account as of the day such compensation would
have been paid, the number of deferred shares which is equal to the number of
common shares that would otherwise have been delivered to the director pursuant
to the plan. The deferred shares credited to the director's account (plus any
additional shares credited as dividends) will represent the number of common
shares that the Company will issue to the director at the end of the deferral
period. The deferred shares are subject to a deferral period beginning on the
date of crediting to the director's account and ending upon termination of
service as a director or such other period as the director may have elected. The
deferral period will be for a minimum period of one year (except if the director
elects a deferral period determined by reference to his or her termination of
service as a director). During the deferral period, the director will have no
right to transfer any rights in the deferred shares and will have no other
rights of ownership in such deferred shares. Payment of a director's account may
be accelerated in certain events, such as death or an unforeseeable emergency.

      A director's account will be credited each calendar quarter with
additional deferred shares equal in value to the amount of cash dividends, if
any, paid by us during such quarter. The dividend equivalents will be credited
with additional dividend equivalents and will be deferred until the end of the
deferral period for the deferred shares with respect to which the dividend
equivalents were credited.

      Eligibility

      Each member of Omnicom's Board who is not an employee or former employee
of Omnicom is eligible to participate in the plan. There are currently nine
directors eligible to participate in the plan.

      Termination and Amendment

      The plan provides that the Board may at any time terminate, suspend or
amend the plan, but no amendment or termination will adversely affect the right
of a director to receive common shares issuable or cash payable at the effective
date of the amendment or termination.

Federal Income Tax Consequences

      The following is a summary of the federal income tax treatment of the
income deferral actions under the plan based on federal income tax laws in
effect on the date of this proxy statement.

      Common shares whose receipt is not deferred at the election of a director
will constitute taxable income to the individual director and a deductible
expense to us in an amount equal to the fair market value of the shares in the
year in which the shares are issued.

      Shares that a director elects to defer under the plan will become subject
to federal income taxation to the director only when the shares are actually
paid to the director. We will become entitled to a compensation expense
deduction at the same time. The same treatment applies to dividends credited to
the director's account during the period of deferral.


                                       16


Plan Benefits

      In fiscal year 2004, each eligible director will receive common shares
under the plan equal in value to $70,000 plus common shares equal in value to
any additional amounts that the director elects to receive in common shares. The
exact number of shares that the directors will receive cannot be determined as
it will depend on whether the director will elect to receive more than $70,000
of his or her compensation in the form of common shares and on the fair market
value of our common shares on the first trading day immediately preceding the
date on which the compensation is payable. The table below reflects the dollar
value of the common shares and the number of common shares that we anticipate
will be awarded during fiscal year 2004 to the directors currently eligible to
participate in the plan following shareholder approval at the annual meeting.

(1)   The Non-Executive Director Group consists of nine eligible directors. The
      table above reflects the receipt of common shares by each eligible
      director equal in value to $70,000 at an assumed fair market value of
      $80.25 per share, the closing price of our common shares on March 31,
      2004. The table does not reflect the receipt of any common shares that the
      directors may receive because of an election to receive additional
      compensation in common shares.

Board Recommendation

      The Board recommends that shareholders vote FOR the approval of the plan.

      Approval of this proposal requires the favorable vote of the holders of a
majority of the shares voting on the proposal.

                             ADDITIONAL INFORMATION

Record Date; Shares Outstanding

      Shareholders of record at the close of business on April 9, 2004 are
entitled to vote their shares at the annual meeting. As of March 31, 2004, we
had 188,963,336 common shares outstanding and entitled to be voted at the
meeting. The holders of those shares are entitled to one vote per share.

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 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 adoption of the director equity plan
and the ratification of the appointment of KPMG 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. In order
to obtain approval of the election of any nominee as a director, assuming a
quorum exists, a plurality vote is required. Abstentions, broker non-votes and
withheld votes will not be considered as votes cast in favor or against any
proposal. As a result, abstentions, broker non-votes and, in the case of
election of directors, withheld votes, will have no effect on the matters
brought to a vote at the meeting.

whose accounts the shares are held, whether or not vested, on their proxies. In
accordance with the terms of the plan, it will vote all shares for which it does
not receive voting instructions in the same proportion on each issue as it votes
the shares for which it does receive instructions.

      If you are the beneficial owner of shares held in "street name" by a
broker, bank or other nominee, the broker, bank or nominee, as the record holder
of the shares, is required to vote those shares according to your instructions.
Your broker, bank or nominee should have enclosed 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 election of directors and on the ratification
of the appointment of KPMG as our independent auditors, but not on the approval
of the director equity plan.

Default Voting

      If you submit a proxy 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 and for approval of the director equity
plan. 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.

Right To Revoke

      If you submit your proxy, you may change your voting instructions at any
time prior to the vote at the 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 meeting and voting in person.
For shares beneficially owned by you, but held in "street name" by a broker,
bank or other nominee, you may change your vote by submitting new voting
instructions to your broker, bank or nominee.

Tabulation of Votes

      Mellon Investor Services will act as inspectors at the annual meeting.
They will determine the presence of a quorum and will tabulate and certify the
votes.

Proxy Solicitation

      Omnicom will bear all costs of this proxy solicitation. Proxies may be
solicited by mail, in person, by telephone or by facsimile by 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 D.F. King & Co., Inc. to assist
in the solicitation of proxies and will pay customary fees plus reimbursement of
out-of-pocket expenses for those services.

                                                                      APPENDIX A

                             AUDIT COMMITTEE CHARTER

      Purpose: The Audit Committee is a standing committee of the Board. The
Committee's purpose is to assist the Board in carrying out its oversight
responsibilities relating to the Company's financial reporting. In this regard,
the Committee will assist Board oversight of (1) the integrity of the Company's
financial statements, (2) the Company's compliance with legal and regulatory
requirements, (3) the qualifications and independence of the Company's
independent auditor, and (4) the performance of the Company's internal audit
function and independent auditor. The Company recognizes, however, that:

      o     Management is responsible for determining that the Company's
            financial statements and related disclosures are prepared in
            accordance with applicable requirements;

      o     The Committee does not have the responsibility to conduct audits or
            other reviews; rather, the Committee will take such actions as it
            determines to be appropriate to assure that the Company has
            procedures and processes in place to provide reasonable assurance
            that the Company's financial statements and related disclosures
            comply with applicable requirements; and

      o     In carrying out their oversight responsibilities, the Committee and
            the Board will necessarily rely on the expertise, knowledge and
            integrity of management, the Company's internal and outside auditors
            (collectively, "management and the accountants") and such other
            persons, if any, with whom the Committee may consult from time to
            time.

      The Committee will have the authority to take all actions on behalf of the
Board as the Committee or its Chairperson may from time to time determine to be
consistent with its purpose and this Charter.

      Composition: The Committee will have at least three members. Based upon
the recommendation of the Governance Committee, the Board will designate the
members of the Committee at least annually and will take such actions as it from
time to time determines to be appropriate to assure that the Committee and its
members comply with applicable independence requirements. Management is directed
to take such steps as are necessary to assure that the Company does not take
actions which would compromise the independence of any Committee member. In
furtherance of these requirements, (1) each Committee member will receive only
director's fees as compensation from the Company (which includes all forms of
compensation paid to directors of the Company for service as a director or
member of a Board Committee) and (2) no Committee Member will accept appointment
or election to serve simultaneously on more than three audit committees of
publicly traded companies without first notifying the Chairpersons of the Board
and the Committee a sufficient time in advance to permit the Board to ascertain
whether such service would impair the ability of such member to effectively
serve on the Committee.

      The Board also will from time to time designate the Chairperson, and may
designate a Co-Chairperson or Vice Chairperson, of the Committee. The Committee
may delegate one or more of its responsibilities hereunder to any subcommittee
comprised entirely of two or more Committee members. Any such delegation will be
reported to the Chairperson of the Governance Committee.

      Resources: The Committee or its Chairperson may retain at the Company's
expense (in such amount as the Committee or its Chairperson determines to be
appropriate) legal counsel and other third-party advisors as it determines to be
appropriate. Management and the accountants are directed to bring to the
attention of the Committee such matters that the Committee is required by law or
listing requirements to review or as the Committee or its Chairperson may from
time to time designate. Without limitation, management is responsible for
providing the Committee with the information and assistance contemplated by this
Charter and educational and other resources as may be required by law, listing
requirements or GAAP or as the Committee or the Chairperson may request, and
such funding as may be herein contemplated, including funding to pay fees and
disbursements of the independent auditor and any advisor retained by the
Committee or its Chairperson.

      Proceedings: As contemplated by the Audit Committee Responsibilities
Checklist attached to and made a part of this Charter, the Committee will meet
from time to time, not less frequently than quarterly, as necessary to carry out
its responsibilities. The Committee will periodically meet in executive session
and meet separately with representatives of management, the Company's internal
audit staff and the Company's independent auditor


                                      A-1


to aid in assuring direct communications relevant to the discharge of the
Committee's responsibilities. The Committee may otherwise adopt such procedures
as it or the Chairperson may from time to time determine to be appropriate to
assist in the discharge of its responsibilities. Except as the Committee or its
Chairperson may otherwise determine, the Secretary or another person designated
for this purpose by the Committee Chairperson will prepare appropriate records
of all Committee meetings and actions, copies of which when approved by the
Committee or its Chairperson will be furnished to the Board, and will maintain
copies of all materials furnished or presented to the Committee. In addition,
the Committee Chairperson will report to the Board as to all matters that he or
she determines to be appropriate.

      Responsibilities: The Committee will:

      o     Act as the direct contact with the Company's independent auditor,
            which firm will ultimately be accountable to the Committee and the
            Board;

      o     Have authority and responsibility for the (1) appointment or removal
            of the outside auditor, (2) terms of engagement and compensation of
            the outside auditor, and (3) general oversight on behalf of the
            Board of the work of the outside auditor (including resolution of
            disagreements between management and the outside auditor regarding
            financial reporting), in each case for the purpose of conducting any
            audit or related work;

      o     Pre-approve all audit and non-audit work provided to the Company by
            the outside auditor (except for items exempt from pre-approval
            requirements under applicable law); and

      o     Act in respect of such other matters as to which audit committee
            action is required by law or listing requirements, including in
            respect of the matters specified in the Audit Committee
            Responsibilities Checklist attached to and made a part of this
            Charter.

      The Committee will review this Charter and the Audit Committee
Responsibilities Checklist at least annually and will recommend to the
Governance Committee changes in the Charter or the Audit Committee
Responsibilities Checklist as it determines to be appropriate. Any changes will
be effective when recommended by the Governance Committee and approved by the
Board.

      As adopted by the Board of Directors on March 31, 2003, and amended on
February 2, 2004.

common shares on an annual basis to members of Omnicom's Board who are not
employees or former employees and to otherwise allow these directors to
participate in the ownership of Omnicom's common shares.

      2. Administration.

      (a)   The Plan will be administered by the Compensation Committee of
            Omnicom's Board of Directors, which will have full power and
            authority, subject to the provisions of the Plan, to supervise
            administration, and to interpret the provisions, of the Plan and to
            authorize and supervise any issuance or payment of common shares and
            any crediting or payment of Deferred Shares (as defined in Section 6
            below). No participant in the Plan will participate in the making of
            any decision with respect to any question relating to common shares
            issued under the Plan to that participant only.

      (b)   Any determination or action of the Committee in connection with the
            interpretation or administration of the Plan will be final,
            conclusive and binding on all parties. No member of the Committee
            will be liable for any determination made, or any decision or action
            taken, with respect to the Plan or any issuance of common shares
            under the Plan.

      3. Eligibility. Each member of Omnicom's Board who is not an Omnicom
employee or a former Omnicom employee will be eligible to receive common shares
in accordance with this Plan, provided that shares remain available for issuance
hereunder in accordance with Section 4.

      4. Shares Subject to the Plan. The shares that may be issued or credited
to accounts pursuant to Section 6 of the Plan will be 50,000 common shares,
subject to adjustment in accordance with Section 11. Common shares that may be
issued or credited to accounts under Section 7(a) will not be counted against
this limit. The adoption of the Plan constitutes a reservation of 50,000 common
shares for issuance under the Plan.

      5. Compensation in General. The amount of the director retainer fee, the
director fees for attendance at meetings of Omnicom's Board and/or committees
thereof and any other compensation paid to the directors for services as a
director (collectively, the "Director Compensation") will be determined from
time to time in accordance with Omnicom's By-laws and applicable law.

      6. Compensation in the Form of Common Shares. Each participant will
receive on a quarterly basis a number of common shares equal to $17,500 (or such
other amount as determined by the Board from time to time) divided by the Fair
Market Value (as defined in Section 9(a) below) of one common share on the day
immediately preceding the date of the award for services to be performed in the
following quarter. The first quarterly payment will be paid on the first
business day following the annual meeting of Omnicom's shareholders. Each
participant may elect to have such common shares paid in the form of deferred
shares ("Deferred Shares"), which will be credited to a book-keeping account in
the name of the participant in accordance with this Plan. Such shares will count
against the maximum number of shares authorized and reserved for issuance under
the Plan.

      7. Further Elections.

      (a)   Each Participant may elect to have all or any portion of the
            remainder of his or her Director Compensation payable in cash or
            common shares and may further elect to have any Director
            Compensation that the participant has elected to receive in common
            shares paid in the form of Deferred Shares, which will be credited
            to the participant's account. For the portion of a participant's
            Director Compensation that he or she elects to receive in common
            shares, the number of common shares to be issued will equal the cash
            amount that would have been paid divided by the Fair Market Value of
            one common share on the day immediately preceding the date on which
            such cash amount would have been paid.


                                      B-1


      (b)   An election pursuant Section 6 and 7(a) must be made in writing and
            delivered to Omnicom prior to the start of the calendar year for
            which the Director Compensation would be payable and such election
            will be irrevocable for the affected calendar year (the "Affected
            Year"). To elect to defer shares during the calendar year in which
            the Plan becomes effective, the participant must make an election
            pursuant to Section 6 and 7(a) prior to the date on which the
            Director Compensation will become earned and payable and such
            election will be irrevocable for the remainder of the Affected Year.
            To elect to defer shares during the first calendar year in which a
            director becomes eligible to participate in the Plan, the new
            director must make an election pursuant to Section 6 and 7(a) prior
            to the date on which the Director Compensation will become earned
            and payable and such election will be irrevocable for the remainder
            of the Affected Year. Each election will remain in effect until
            revoked in writing, and any such revocation will become effective no
            earlier than the first day of the first calendar year commencing
            after such revocation is received by Omnicom. If a director does not
            file an election form by the specified date, he or she will receive
            $70,000 worth (or such other amount as determined by the Board from
            time to time) of his or her Director Compensation for the year in
            common shares on a current basis and will be deemed to have elected
            to receive the remainder of the Director Compensation in cash.

      8. Deferral.

      (a)   If a participant elects to receive Deferred Shares, there will be
            credited to the participant's account as of the day such Director
            Compensation would have been paid, the number of Deferred Shares
            which is equal to the number of common shares that would otherwise
            have been delivered to the Participant pursuant to Section 6 and/or
            Section 7(a) on such date. The Deferred Shares credited to the
            participant's account (plus any additional shares credited pursuant
            to Section 8(c) below) will represent the number of common shares
            that Omnicom will issue to the participant at the end of the
            deferral period.

      (b)   The Deferred Shares will be subject to a deferral period beginning
            on the date of crediting to the participant's account and ending
            upon termination of service as a director or such other period as
            the participant may have elected. The period of deferral will be for
            a minimum period of one year, except in the case where the
            participant elects a deferral period determined by reference to his
            or her termination of service as a director. During the deferral
            period, the participant will have no right to transfer any rights
            under his or her Deferred Shares and will have no other rights of
            ownership therein.

      (c)   A participant's account will be credited as of the last day of each
            calendar quarter with that number of additional Deferred Shares
            equal to the amount of cash dividends paid by Omnicom during such
            quarter on the number of common shares equivalent to the number of
            Deferred Shares in the participant's account from time to time
            during such quarter divided by the Fair Market Value of one common
            share on the day immediately preceding the last business day of such
            calendar quarter. Such dividend equivalents, which will likewise be
            credited with dividend equivalents, will be deferred until the end
            of the deferral period for the Deferred Shares with respect to which
            the dividend equivalents were credited.

      (d)   Notwithstanding the foregoing provisions, (i) if, upon the
            participant's termination of service as a director, the value of the
            participant's account is less than $500, the amount of such
            participant's account, at the discretion of the Board, may be
            immediately paid to the participant in cash or common shares, (ii)
            if a change in control of Omnicom occurs, the amount of each
            participant's account will immediately be paid to the participant in
            full and (iii) in the event of an unforeseeable emergency, as
            defined in section 1.457-2(h)(4) and (5) of the Income Tax
            Regulations, that is caused by an event beyond the control of the
            participant and that would result in severe financial hardship to
            the individual if acceleration were not permitted, the Board may in
            its sole discretion accelerate the payment to the participant of the
            participant's account, but only up to the amount necessary to meet
            the emergency.


                                      B-2


      9.  Definitions, etc.

      (a)   For purposes of this Plan, the Fair Market Value of the common
            shares on any date means (i) the closing sale price per common share
            as reported on the principal exchange on which common shares are
            then trading, if any, or if there are no sales on such day, on the
            next preceding trading day during which a sale occurred or (ii) if
            clause (i) does not apply, the fair market value of a common share
            as determined by the Board.

      (b)   Notwithstanding anything to the contrary contained in this Plan, it
            is a condition to the issuance of common shares or Deferred Shares
            that the transaction be registered under applicable securities laws
            and no participant will be able to receive common shares or Deferred
            Shares in payment of all or part of his or her Director Compensation
            unless and until such registration has been effected.

      10. Delivery of Shares. Omnicom will make delivery of certificates
representing the common shares which a participant is entitled to receive within
a reasonable period of time.

      11. Adjustments. In the event that, after the Effective Date of this Plan
(as defined in Section 14), the number of outstanding common shares is increased
or decreased or such shares are exchanged for a different number or kind of
shares or other securities by reason of a recapitalization, reclassification,
stock split-up or combination of shares, adjustments will be made by the Board
in the number and kind of shares or other securities that are credited to
accounts hereunder and that may be issued under this Plan as it deems to be
appropriate.

      12. Termination or Amendment of the Plan. The Board may at any time
terminate, suspend or amend the Plan. An amendment or the termination of this
Plan will not adversely affect the right of a participant to receive common
shares issuable or cash payable at the effective date of the amendment or
termination.

      13. Miscellaneous.

      (a)   The rights, benefits or interests a participant may have under this
            Plan are not assignable or transferable and will not be subject in
            any manner to alienation, sale or any encumbrances, liens, levies,
            attachments, pledges or charges of the participant or his or her
            creditors.

      (b)   To the extent that the application of any formula described in this
            Plan does not result in a whole number of common shares, the result
            will be rounded upwards to the next whole number.

      (c)   The adoption and maintenance of this Plan will not be deemed to be a
            contract between Omnicom and the participant to retain his or her
            position as a director of Omnicom.

      14. Effective Date of the Plan. The Plan will be effective immediately
upon the date of its approval by the shareholders of Omnicom (the "Effective
Date"). If this Plan is so approved, no new awards may be granted under
Omnicom's restricted stock plan for non-employee directors, but outstanding
restricted shares under the restricted stock plan for non-employee directors
will not be affected.
