Dear Stockholder:

        You are cordially invited to attend the Annual Meeting of Stockholders of The Interpublic Group of Companies, Inc., to be held at 9:30 A.M. Eastern Time, on Tuesday, May 18, 2004. The meeting will be held in the MT&R Theater of The Museum of Television & Radio, 25 West 52nd Street, New York, New York.

        The business to be considered is described in the attached notice of the meeting and Proxy Statement. In addition to these matters, we will present a report on the state of our company.

        Last year was an important period in the history of Interpublic, as we began a necessary turnaround under a new management team. Our initial efforts proved very successful in stabilizing the company and paving the way for its recovery. We began to change the corporate culture to one focused on organic growth and governed by greater accountability. We will continue on this path as we look to reinvent Interpublic and make it into the organization that best understands and leverages the new realities that are transforming how our clients approach marketing.

        Major corporate accomplishments in 2003 spanned a number of key areas:


Much was accomplished at Interpublic in the past year. We established a solid base from which to launch the second phase of the turnaround program. There remains much work to be done. We look forward to discussing our progress and our plans with you at the Annual Meeting. We will also provide an opportunity for shareholders to voice questions or comments. And we will share a sampling of work recently produced by a range of our companies.

        We hope you will be able to attend.

      Sincerely,

Voting

        Election of directors will be decided by a plurality of the votes cast by the holders of shares of Common Stock present in person or represented by proxy at the meeting and entitled to vote. Approval of Items 2 through 5 will require the affirmative vote of the holders of a majority of the shares present in person or represented by proxy at the meeting and entitled to vote. Interpublic's transfer agent tabulates the votes. Abstentions and broker non-votes are each tabulated separately and are counted as shares present for the purpose of determining whether there is a quorum present for the conduct of business at the Annual Meeting. For Items 2 through 5, shares that are the subject of an abstention are included, as shares entitled to vote on the matter and, therefore, have the same effect as a vote against the matter, and shares, if any, that are the subject of a broker non-vote with respect to a particular matter are not included as shares entitled to vote on that matter.

Stockholder Proposals To Be Presented At 2005 Annual Meeting

        Proposals of stockholders intended to be presented at the Annual Meeting of Stockholders scheduled to be held on May 17, 2005, must be received by Interpublic by December 27, 2004, and must comply with applicable SEC regulations, in order to be considered for inclusion in Interpublic's Proxy Statement and form of proxy relating to that meeting. If notice of a proposal intended to be presented at the Annual Meeting is not received by Interpublic before March 14, 2005, the persons named as proxies in Interpublic's 2005 proxy material will have the discretionary authority to vote on the matter in accordance with their best judgment without disclosure in the proxy statement of such matter or of how the proxy holders intend to exercise their discretionary authority to vote on the matter.

CORPORATE GOVERNANCE PRACTICES AND BOARD MATTERS

Corporate Governance Guidelines

        Interpublic has a strong commitment to sustaining sound corporate governance practices. Interpublic's Corporate Governance Guidelines are available free of charge on Interpublic's website at http://www.interpublic.com or by writing to The Interpublic Group of Companies, Inc., 1271 Avenue of the Americas, New York, NY 10020, Attention: Secretary.

Board Structure, Committees and Independence

        Interpublic has ten directors, three of whom are employees of Interpublic or one of its subsidiaries (those employee Directors are referred to hereinafter in this Proxy Statement as "Management Directors") and seven of whom are not employees of Interpublic or its subsidiaries (those non-employee Directors are referred to hereinafter in this Proxy Statement as the "Non-Management Directors" or "Outside Directors"). Committees of the Board include the Executive Committee, the Finance

6


Committee, the Compensation Committee, the Corporate Governance Committee and the Audit Committee. The activities of the Compensation Committee, the Corporate Governance Committee and the Audit Committee are each governed by a charter that is available free of charge on Interpublic's website at http://www.interpublic.com or by writing to The Interpublic Group of Companies, Inc., 1271 Avenue of the Americas, New York, NY 10020, Attention: Secretary. A description of the responsibilities of each Committee of the Board is provided in this Proxy Statement under the heading "Principal Committees of the Board of Directors". All of the members of the Compensation, Corporate Governance and Audit Committees are Non-Management Directors. Of the seven Non-Management Directors, the Board has determined that Ms. Considine and Messrs. Brack, Goldstein, Greeniaus, Roth and Samper are each independent under the independence standards set forth in Interpublic's Corporate Governance Guidelines, and under the applicable rules of the SEC and the New York Stock Exchange ("NYSE") listing standards which will take effect for Interpublic as of May 18, 2004 (the "NYSE Listing Standards"). Under the NYSE Listing Standards, Mr. Borelli, Interpublic's Presiding Director as described below, is not deemed to be independent because his son is a principal of Deloitte & Touche, to which Interpublic has outsourced its internal audit function. Mr. Borelli's son is not engaged in providing services to Interpublic.

Presiding Director

        Interpublic created the position of Presiding Director of the Board in November 2002. The Presiding Director of the Board helps to coordinate communications between the Board and management of Interpublic. Specifically, the Presiding Director convenes and chairs meetings of the Non-Management Directors, coordinates and develops the agenda for, and chairs executive sessions of, the Non-Management Directors, coordinates feedback to the Chairman and Chief Executive Officer on behalf of the Non-Management Directors regarding business issues and management, and coordinates and develops with the Chairman of the Board and Chief Executive Officer the agendas and presentations for meetings of the Board together with the informational needs associated with those agendas and presentations. In addition, the Presiding Director meets monthly with Interpublic's major business units to ensure an understanding of their issues and needs and to communicate observations to the Non-Management Directors. The Non-Management Directors have elected Mr. Borelli as Presiding Director for a second term of one year, effective as of November 2003.

        The NYSE Listing Standards require that if the group of Non-Management Directors includes one or more directors that is not independent, then at least once annually, the Non-Management Directors should hold an executive session that includes only independent Directors. At the meeting of the Board in February 2004, the independent Directors met in executive session without Mr. Borelli. Ms. Considine served as the Chairperson of that executive session of the Non-Management Directors.

Communications with the Board of Directors and Non-Management Directors

        Interested parties may contact Interpublic's Board of Directors, or the Non-Management Directors as a group, at the following address:

        Communications may also be sent to individual directors at the above address. Communications to the Board, the Non-Management Directors or to any individual director that relate to Interpublic's accounting, internal accounting controls or auditing matters will also be referred to the Chairperson of the Audit Committee. Other communications will be referred to the Presiding Director or the appropriate committee chairperson.

Director Selection Process

        The Corporate Governance Committee is charged with the responsibilities described in this Proxy Statement under the heading "Principal Committees of the Board of Directors—Corporate Governance Committee".

        One of the Committee's responsibilities is to identify and recommend to the Board candidates for election as directors. The Committee considers candidates suggested by its members, other directors, senior management and shareholders as necessary in anticipation of upcoming director elections or due to Board vacancies. The Committee is given broad authorization to retain, at the expense of Interpublic, external legal, accounting or other advisers including the retention of search firms to identify candidates and to perform "background reviews" of potential candidates. The Committee is expected to provide guidance to search firms it retains about the particular qualifications the Board is then seeking. No search firms or other advisers were retained in the past fiscal year to identify director candidates.

        All director candidates, including those recommended by shareholders, are evaluated on the same basis. Candidates are considered in light of the entirety of their credentials, including:

        In determining the needs of the Board and Interpublic, the Committee considers the qualifications of sitting directors and consults with other members of the Board (including as part of the Board's annual self-evaluation), the CEO and other members of senior management and, where appropriate, external advisers. The Corporate Governance Committee recently has extended the mandatory retirement age of a director from 70 to 74 years old in order to encourage continuity of Board membership at a time when Interpublic and its subsidiaries are engaged in an ambitious turnaround effort. All directors are expected to exemplify the highest standards of personal and professional integrity and to assume the responsibility of challenging management through their active and constructive participation and questioning in meetings of the Board and its various committees, as well as in less formal contacts with management.

        Director candidates, other than sitting directors, are interviewed by each of the members of the Committee and by other directors, the CEO and other key management personnel, and the results of those interviews are considered by the Committee in its deliberations. The Committee also reviews sitting directors whose terms are nearing expiration, and who are considered potential candidates for re-election, in light of the above considerations and their past contributions to the Board.

        Shareholders wishing to recommend a director candidate to the Committee for its consideration should write to the Committee, in care of its Chairperson, at The Interpublic Group of Companies, Inc., 1271 Avenue of the Americas, New York, NY 10020. Any recommendations will be considered for the next

8


annual election of directors in 2005. A recommendation should include the candidate's name, biographical data and a description of his or her qualifications in light of the above criteria. If Interpublic receives in a timely manner, in accordance with the SEC requirements, any recommendation of a director candidate from a shareholder, or group of shareholders, that beneficially owns more than 5% of Interpublic's Common Stock for at least one year as of the date of recommendation, as determined under SEC rules, Interpublic will disclose in its proxy statement the names of the recommending shareholder(s) and the candidate if the shareholder (or each member of the group) and the candidate consent in writing to that disclosure.

Principal Committees of The Board of Directors

        Executive Committee—The Executive Committee is authorized, when the Board of Directors is not in session, to exercise all powers of the Board of Directors which, under Delaware law and the By-Laws of Interpublic, may properly be delegated to a committee, except certain powers that have been delegated to other committees of the Board of Directors. Due to the frequency in number of meetings of the Board and other committees of the Board, the Executive Committee did not hold any meetings in 2003.

        Finance Committee—The Finance Committee is authorized to review the financial affairs of Interpublic and make recommendations with respect thereto to the Board of Directors. It also approves capital budgets, guarantees by Interpublic of obligations of subsidiaries and affiliates and certain capital transactions (including mergers and acquisitions), and is the committee that administers the Interpublic Retirement Account Plan. The Finance Committee held five meetings in 2003.

        Compensation Committee—The Compensation Committee is responsible for the adoption and periodic review of a remuneration strategy for Interpublic and its subsidiaries which ensures that executive compensation for key senior executives is designed to incentivize and reward long-term growth, profitability and return to stockholders. The Compensation Committee is responsible for approving the compensation paid to senior executives of Interpublic and its subsidiaries. For these purposes, compensation is deemed to include: (1) salary, (2) deferred compensation, (3) bonuses and other extra compensation of all types, including long-term performance incentive awards under Interpublic's 2002 Performance Incentive Plan, (4) insurance paid for by Interpublic or any of its subsidiaries other than group plans, (5) annuities and individual retirement arrangements, (6) Special Deferred Benefit Agreements, (7) Interpublic's Senior Executive Retirement Income Plan ("SERIP"), and (8) Interpublic's Capital Accumulation Plan. The Compensation Committee also administers the 2002 Performance Incentive Plan (and its predecessors, the 1997 Performance Incentive Plan, the Long-Term Performance Incentive Plan, the Management Incentive Compensation Plan, the 1996 Stock Incentive Plan and the 1986 Stock Incentive Plan), the 1986 United Kingdom Stock Option Plan and the Employee Stock Purchase Plan (1995). The Committee approves any newly adopted or major changes made to these plans and makes recommendations to the Board with respect to incentive-compensation plans and equity-based plans. The Committee also reviews initiatives of Interpublic and its subsidiaries to retain and develop key employees on an ongoing basis and coordinates, manages and reports to the Board on the annual performance evaluation of key executives of Interpublic. In addition, the Committee is authorized, if appropriate, to hire experts or other independent advisers or legal counsel to assist the Committee in the discharge of its duties. The Compensation Committee held seven meetings in 2003.

        Corporate Governance Committee—The Corporate Governance Committee is responsible for recommending to the Board of Directors the persons to be nominated for election to the Board of Directors and the membership and chairman of each Board committee. The other responsibilities of the Corporate Governance Committee include the establishment of criteria for membership on the Board and its committees, the review and recommendation to the Board as to the independence of Non-Management Directors under the standards set forth in Interpublic's Corporate Governance Guidelines and the NYSE Listing Standards, the evaluation on an annual basis of the collective performance of the Board and the Board's committees, the recommendation to the Board of compensation and benefits for Non-Management Directors, and the review, the continual assessment and the recommendation to the Board of the best practices in corporate governance matters generally. The Corporate Governance Committee held four meetings in 2003.

9

        The Audit Committee—The Audit Committee assists the Board in fulfilling its oversight responsibilities with respect to (i) the annual financial information to be provided to stockholders and the SEC; (ii) the system of internal controls that management has established; and (iii) the internal and external audit processes. In addition, the Audit Committee provides an avenue for communication among internal audit, the independent auditors, financial management and the Board. The Audit Committee also is responsible for the selection and retention of Interpublic's independent auditors and the review of their compensation, subject to approval of the Board of Directors. Specific activities of the Committee are described in the Audit Committee Report below. In light of the importance of the Audit Committee, on the recommendation of the Corporate Governance Committee, each independent Non-Management Director is a member of the Audit Committee. The Board has determined that each member of the Audit Committee qualifies as an "audit committee financial expert" within the meaning of applicable SEC rules. The Audit Committee held eight meetings in 2003.


AUDIT COMMITTEE REPORT

        The primary function of the Audit Committee is to assist the Board of Directors in its oversight of Interpublic's financial reporting process. The Committee operates pursuant to a Charter approved by the Board. A copy of the Charter is included as Appendix A of this Proxy Statement.

        Management is responsible for Interpublic's consolidated financial statements and overall reporting process, including the system of internal controls. PricewaterhouseCoopers LLP, the independent auditor of Interpublic, is responsible for conducting annual audits and timely quarterly reviews of Interpublic's consolidated financial statements and expressing an opinion as to the conformity of the annual consolidated financial statements with generally accepted accounting principles. With respect to the year ended December 31, 2003, the Audit Committee has:

10

        Based on the review and discussions referred to above, the Audit Committee recommended to the Board of Directors that the audited consolidated financial statements be included in Interpublic's Annual Report on Form 10-K for the year ended December 31, 2003.

Attendance at Board of Directors and Committee Meetings

        The Board of Directors has articulated in its Corporate Governance Guidelines its policy with respect to attendance of each director at Board meetings. Specifically, the Corporate Governance Guidelines provide that each director is expected to prepare for, attend and participate in, at least 75% of all meetings of the Board, absent special circumstances. The Board of Directors of Interpublic held fourteen meetings in 2003 and committees of the Board held a total of twenty-four meetings. During 2003, each director attended 75% or more of the total number of meetings of the Board of Directors and committees on which he or she served, except for Mr. Samper who attended 72% (representing 21 out of 29) of the meetings of the Board and committees on which he served.

Attendance at Annual Meeting of Stockholders

        Interpublic does not have a specific policy for attendance by directors at the Annual Meeting of Stockholders. However, all directors who are currently members of the Board and who are standing for re-election attended the 2003 Annual Meeting.

Non-Management Directors' Compensation

        Each Non-Management Director receives as cash compensation for services rendered, an annual retainer of $40,000, an annual retainer of $2,000 for each committee on which he or she serves, a fee of $1,500 for each meeting of the Board attended and a fee of $1,500 for each committee meeting attended. The Chairperson of the Compensation Committee, the Chairperson of the Finance Committee and the Chairperson of the Corporate Governance Committee each receives an additional retainer of $7,500 per year and the Chairperson of the Audit Committee receives an additional retainer of $10,000 per year.

        As Presiding Director of the Board, Mr. Borelli receives an annual retainer of $200,000.

        Each Non-Management Director also receives, as consideration for services rendered as a member of the Board, stock-based compensation under the Interpublic Outside Directors' Stock Incentive Plan (formerly called the Interpublic Outside Directors' Stock Option Plan), which was approved by the

11


stockholders in 1994 (the "Outside Directors' Plan"). Effective August 1, 2003, the Board amended the Outside Directors' Plan to provide for an annual grant to each Non-Management Director of (i) 800 shares of Interpublic Common Stock that are not subject to transfer restrictions or forfeiture (the "Freely Tradeable Shares") and (ii) 1,600 restricted shares of Interpublic Common Stock ("Restricted Shares"). The amendment provided that the initial grants would be made in August 2003 and subsequent grants would be made each January while the Plan remains in effect. With respect to the Restricted Shares, the recipient has all rights of ownership, including the right to vote and to receive dividends, except that, prior to the expiration of a three-year period after the date of grant (the "Restricted Period"), the recipient is prohibited from selling or otherwise transferring the shares. If, on or after the first anniversary of the grant, the recipient's service as a director terminates for any reason (including death) during the Restricted Period, the restrictions on transfer will lapse immediately in proportion that the number of months that have elapsed since the date of grant bears to the total number of months of the Restricted Period, and the remainder of such Restricted Shares will be forfeited. If the recipient's service as a director terminates for any reason (including death) before the first anniversary of the date of grant, all such Restricted Shares will be forfeited. The Corporate Governance Committee, which is responsible for the administration of the Outside Directors' Plan, may in its discretion direct Interpublic to make cash payments to the recipient of Restricted Shares to assist in satisfying the federal income tax liability with respect to the receipt or vesting of the Restricted Shares.

        On August 1, 2003, each of Ms. Considine and Messrs. Borelli, Brack, Goldstein, Greeniaus, Roth and Samper received a grant of 800 Freely-Tradeable Shares of Common Stock and a grant of 1,600 Restricted Shares. In 2004, in accordance with the Plan, each of Ms. Considine and Messrs. Borelli, Brack, Goldstein, Greeniaus, Roth and Samper received an additional grant of 800 Freely-Tradeable Shares and 1,600 Restricted Shares.

        Mr. Goldstein and Ms. Considine each has an agreement with Interpublic for the deferral of all fees that the individual is entitled to receive as a director or as a member of any committee of the Board of Directors. The amounts deferred earn credits equivalent to interest in accordance with the terms of Interpublic's Plan for Credits Equivalent to Interest on Balances of Deferred Compensation Owing under Employment Agreements. Payments of the amounts deferred, together with accrued interest, will be made to the director, or his designated beneficiaries as the case may be, in a lump-sum upon the director's death, disability or retirement from the Board.

        Each outside director who, as of December 31, 1995, had accumulated at least five years of service is entitled to receive an annual retirement benefit under the Interpublic Outside Directors' Pension Plan (the "Outside Directors' Pension Plan"). In general, the benefit becomes payable in the month following the month the director leaves the Board. The benefit is equal to the amount of the annual retainer paid to the director as a Board member in the year in which he or she ceased to serve as a director and will be paid for the same number of years as the director's years of service, up to a maximum of 15 years. In the event of the death of a director with a vested retirement benefit, the then present value of the director's unpaid retirement benefits will be paid to the surviving spouse or the estate of the director. Effective December 31, 1995, the Outside Directors' Pension Plan was terminated, except to the extent benefits were accrued prior to termination. As a result there have been no further accruals for the benefit of existing directors under the Outside Directors' Pension Plan for subsequent years. Any director with fewer than five years of service on the date that the Plan was terminated will not receive any benefits under the Plan. Mr. Samper is the only current director who participates in this plan.


CODE OF CONDUCT

        Interpublic has adopted a code of ethics, known as the Code of Conduct, which applies to all employees of Interpublic and its subsidiaries and affiliates. Interpublic's Corporate Governance Guidelines provide that members of the Board of Directors and officers (which includes Interpublic's Chief Executive Officer, Chief Financial Officer, Controller and other persons performing similar functions) must comply with the Code of

12


Conduct. In addition, the Corporate Governance Guidelines state that the Board will not waive any provision of the Code of Conduct for any Director or executive officer. The Code of Conduct, including future amendments, is available free of charge on Interpublic's website at http://www.interpublic.com or by writing to The Interpublic Group of Companies, Inc., 1271 Avenue of the Americas, New York, NY 10020, Attention: Secretary.


CHANGE OF ADDRESS

        Interpublic will be moving its corporate headquarters during the second quarter of 2004. Please consult Interpublic's website at http://www.interpublic.com for the effective date of the move. After the move, all written communication to members of the Board of Directors or a Chairperson of a Board Committee, as applicable, should be sent to The Interpublic Group of Companies, Inc., 1114 Avenue of the Americas, New York, NY 10036. After the move, any written requests for Interpublic's Corporate Governance Guidelines, By-Laws or Code of Conduct should be sent to the attention of Interpublic's Secretary at the new address provided above.


COMPENSATION OF EXECUTIVE OFFICERS

        The following table sets forth information concerning the compensation paid by Interpublic and its subsidiaries to (i) Messrs. Bell and Dooner, each of whom served as the Chief Executive Officer during 2003, (ii) each of the four most highly compensated executive officers of Interpublic other than either CEO (based on aggregate salary and bonus in 2003), who were serving as executive officers on December 31, 2003 and (iii) two additional individuals who ceased to be executive officers during 2003 who, based on their 2003 compensation, would have been among the four most highly compensated executive officers of Interpublic for 2003 if they had been serving as executive officers on December 31, 2003 (the "named executive officers"). In each instance, this compensation shown is for services rendered in all capacities for the three-year period ended on December 31, 2003. As used in this Proxy Statement, the executive officers of Interpublic include any director of Interpublic who served as the chief executive officer of McCann-Erickson WorldGroup, a significant operating unit of Interpublic.

Under the agreement (i) a restricted stock award granted on November 18, 2002 in the amount of 21,300 shares will vest as to 15,975 shares on February 28, 2005; (ii) 13,309 shares of the April 2003 Award will vest on February 28, 2005; (iii) a restricted stock award granted on November 10, 2003 in the amount of 102,233 shares (the "November 2003 Award") will vest as to 18,255 shares on February 28, 2005; and (iv) a restricted stock award granted on November 18, 2003 in the amount of 2,400 shares will vest as to 600 shares on February 28, 2005. The restricted stock awards that do not vest on an accelerated basis under the Separation Agreement will be forfeited by Mr. Brooks, except for the November 2003 Award which will vest in full on January 31, 2008 if Mr. Brooks abides by a non-solicitation provision of the Separation Agreement through that date. The November 2003 Award was originally granted to Mr. Brooks together with a retirement benefit under The Interpublic Senior Executive Retirement Income Plan as consideration for his cancellation of a Special Deferred Benefit Agreement that Interpublic provided him at the time he had joined Interpublic in recognition of his forfeiture of certain benefits that he had received from his prior employer.


Mr. Krakowsky received an award of 50,000 shares of restricted stock on April 1, 2003, 16,500 shares of which vested on April 1, 2004 and another 16,500 shares of which will vest on April 1, 2005. The balance will vest on April 1, 2006. This award was made to Mr. Krakowsky at the time of his periodic review in recognition of his performance.


Mr. Nelson received an award of 25,000 shares of restricted stock on April 1, 2003, 8,250 shares of which vested on April 1, 2004 and 8,250 of which will vest on April 1, 2005. The balance will vest on April 1, 2006. He also received an award of 15,000 shares of restricted stock on April 29, 2003, 4,950 shares of which will vest on April 29, 2004, and another 4,950 shares will vest on April 29, 2005.

Options granted in 2001 include an option to purchase 131,100 shares of Interpublic Common Stock issued to Mr. Bell in replacement of stock options held by him under a stock option plan of True North. This option was granted in connection with Interpublic's acquisition of True North. During 2003, Mr. Bell voluntarily cancelled 131,100 of the 256,100 shares of Interpublic's Common Stock underlying stock options that he received in 2001. He relinquished these option awards with the express intent of permitting the underlying shares to be issued to other employees of Interpublic under the 2002 Performance Incentive Plan.


During 2003, Mr. Dooner voluntarily cancelled option awards with respect to 248,000 shares and 252,000 shares of Common Stock that were granted to him on March 24, 2000 and December 15, 2000, respectively. These awards are not required to be reported in this Proxy Statement but were reported in previous years. Mr. Dooner relinquished these grants with the express intent of permitting the underlying shares to be issued to employees of an Interpublic subsidiary under the 2002 Performance Incentive Plan.


On March 26, 2003, the award of stock options granted to Mr. Nelson was cancelled by Interpublic, in exchange for a grant of 15,000 shares of restricted Common Stock that he received on April 29, 2003.


During 2003, Mr. Wilmot voluntarily cancelled a stock option award with respect to 18,000 shares of Common Stock that he received in 2001 and a stock option award with respect to 8,000 shares that he received in 2000. The 2000 stock option award was reported last year in Interpublic's Proxy Statement. He relinquished these option awards with the express intent of permitting the underlying shares to be issued to employees of an Interpublic subsidiary under the 2002 Performance Incentive Plan.


In addition to Messrs. Dooner, Bell and Wilmot, several executives of Interpublic's subsidiaries also voluntarily cancelled options with the express intent of permitting the underlying shares to be issued to other employees of Interpublic and its subsidiaries under the 2002 Performance Incentive Plan. Options to purchase a total of 1,350,348 shares were cancelled (including those awards described above for Messrs. Bell, Dooner and Wilmot). Of this amount, approximately 641,598 shares remain available for reallocation to other employees of Interpublic and its subsidiaries.

(8)
Payouts under the Long-Term Performance Incentive Plan ("LTPIP") prior to 2002 were made at the end of four-year performance periods. In 2002, the original 1999-2002 performance period was shortened to three years in order to institute a new performance plan. Payouts received in 2002 were calculated based on the value of the 1999-2001 performance period at the end of 2001 after giving effect to Interpublic's restructuring costs taken in 2001.


The total payout for the 1997-2000 LTPIP performance period was made in the first quarter of 2001.

Long-Term Incentive Plan Awards in 2003

        The following table presents information regarding awards made to each of the named executive officers under the LTPIP in 2003. However, in December 2003, the Compensation Committee decided to terminate the LTPIP. In order to prepare for the implementation of a new incentive compensation program, and because it became apparent that the performance goals of Interpublic and its subsidiaries for the 2003–2005 performance period would not be achieved, the Committee also decided to determine the payout under the awards made in 2003 in advance of the completion of the performance period. Accordingly, as more fully described below, the information in the table with respect to the estimated future payouts pursuant to the 2003 awards, which is provided in accordance with Securities and Exchange Commission rules, does not reflect the payment, if any, that actually will be received.

Under a Confidential Separation Agreement and General Release, Mr. Brooks will be entitled to retain 3,611 of the 5,000 performance units granted to him under the LTPIP for the 2003-2005 Performance Period. Any amounts payable with respect to these performance units are subject to the terms of the LTPIP. See "Employment Agreements, Termination of Employment and Change-In-Control Arrangements—Termination and Change In Control Agreements—Brian Brooks' Separation Agreement".

20

        The LTPIP as in effect in 2003 provided for annual awards of "performance units" to select employees of Interpublic or its subsidiaries. The value of the performance units, which are settled in cash, was tied to the annual growth of operating income of the office, agency or regional or worldwide agency system with which the employee is principally associated. The performance units awarded in 2003 could increase in value to as much as $225, or could decrease to as little as zero, with the increase or decrease depending in each case on the extent to which the growth rates of operating income of the applicable operating components exceed or fall short of the pre-established compound growth rates in operating income over a period of three calendar years (a "performance period").

        The estimated payout shown on the table is based on an assumed 4% growth in cumulative compound operating income of an operating component during the performance period, resulting in a threshold payout of $20 per performance unit. Failure to reach the threshold growth rate would result in a zero award. A target growth rate of 10% is assumed for purposes of this presentation. This growth rate would result in a target payout of $115 per performance unit. The maximum growth rate objective was 20% resulting in a maximum payout of $225 per performance unit.

        In December 2003, in connection with its decision to terminate the LTPIP, the Compensation Committee assigned a payout value of $38.33 per unit to the 2003 awards made to Interpublic executives other than those employed by one of the operating divisions and valued the 2003 awards to be made to operating division employees using 2003 actual results and 2004 budgeted performance. In accordance with the original payment schedule: (i) one third of the award will be paid in early 2005 and (ii) the remaining two-thirds of the award will be paid in early 2006. Based on these determinations, the payment to the named executive officers in respect of their 2003 LTPIP awards will be as follows:

Name
   Payout Amount
David A. Bell   $ 766,600
John J. Dooner, Jr.     0
Brian J. Brooks (1)     138,410
Nicholas J. Camera     153,320

Philippe Krakowsky     153,320
Bruce S. Nelson     191,650
Gunnar P. Wilmot     153,320

Reflects that Mr. Brooks' award was prorated to 3,611 out of 5,000 performance units granted to him under the LTPIP for the 2003-2005 Performance Period. See "Employment Agreements Termination of Employment and Change-In-Control Arrangements—Termination and Change In Control Agreements—Brian Brooks' Separation Agreement".

Generally, options become exercisable between two and five years after the date of the grant and expire ten years from the grant date. The True North Options generally will vest 40% on August 23, 2004, 30% on August 23, 2005 and 30% on August 23, 2006.

If he ceased to be employed by Interpublic (other than by reason of death) prior to his 59th birthday, he will receive lesser sums but not less than $75,000. If his employment is terminated prior to June 16, 2005 (other than for cause or voluntary resignation), then in addition to any other payments to which he would be entitled under the agreement he would receive an annuity payment of $50,000 per year for 15 years commencing on his 60th birthday.

        If Mr. Coughlin were to die before all payments were made to him under this agreement, Interpublic would make the remainder of the payments to his beneficiaries.

        Mr. Krakowsky is party to an agreement with Interpublic that provides if he dies while employed by Interpublic, his beneficiaries would receive payments of $245,000 per year for fifteen years.

        Mr. Nelson is a party to three agreements with Interpublic. The first agreement provides that if he dies while he is employed by Interpublic, $280,000 per year will be paid to his beneficiaries for 15 years following his death. If he retires, on or after his 60th birthday, Interpublic will make payments to him for 15 years of $280,000 per year. If he retires, resigns or his employment is terminated with Interpublic on or after his 50th birthday but prior to his 60th birthday, he will receive payments for 15 years ranging from $156,000 to $270,160, depending upon the year his employment terminates.

If Mr. Nelson's employment with Interpublic terminates (other than by reason of death) prior to his 55th birthday, he will receive lesser sums not to exceed $600,000.

        The third agreement provides that if he dies while employed by Interpublic, his beneficiaries will receive $85,000 per year for 15 years following his death. If he retires on or after his 61st birthday, Interpublic will make payments to him for 15 years of $85,000 per year, and if he retires, resigns or is terminated by Interpublic on or after his 60th birthday but prior to his 61st birthday, he will receive payments for 15 years of $80,750 per year. If he ceases to be employed by Interpublic for any reason (other than death) prior to his 60th birthday, he will receive a maximum payment of $680,000.

        After Mr. Nelson's employment terminates, if he were to die before all applicable payments were made under these agreements, Interpublic would make the remaining payments to his beneficiaries.

        Mr. Wilmot is a party to four agreements which provide that if he dies while he is employed by Interpublic, an aggregate of $314,000 will be paid to his beneficiaries for 15 years following his death. Alternatively, if he retires, resigns or is otherwise no longer employed by Interpublic on or after his 55th birthday, Interpublic will make payments to him for 15 years in the aggregate ranging from $208,340 to $314,000 per year, depending upon the year his employment terminates.

The fourth agreement provides that if Mr. Wilmot's employment terminates prior to his 55th birthday (other than by reason of death) he would receive a maximum payment of $360,000. Interpublic also has entered into another agreement with Mr. Wilmot which provides that if he dies while employed by Interpublic, $66,000 will be paid to his beneficiaries for 15 years following his death. If he retires, resigns or is otherwise no longer employed by Interpublic on or after his 58th birthday, Interpublic will make payments to him for 15 years ranging from $54,120 to $66,000 per year, depending upon the year that his employment terminates. If Mr. Wilmot's employment terminates prior to his 58th birthday (other than by reason of death) he will be paid lesser sums than described above for this agreement, but not less than $30,000.

        After Mr. Wilmot's employment terminates, if he were to die before all applicable payments were made under these agreements, Interpublic would make the remaining payments to his beneficiaries.

Termination and Change in Control Agreements

David Bell Severance Arrangement

        Effective February 27, 2003, David Bell became Chairman and Chief Executive Officer of Interpublic. Mr. Bell has an employment agreement with True North Communications, Inc. ("True North"), dated January 1, 2000, to which Interpublic became a party when it acquired True North in June of 2001. As amended, the employment agreement provides for the employment of Mr. Bell through March 1, 2005 (the "Employment Period").

25


        The employment agreement also provides that upon (i) the expiration of the Employment Period, if Mr. Bell retires, or Interpublic does not extend the Employment Period or (ii) if Mr. Bell resigns from Interpublic prior to the expiration of the Employment Period (other than upon a Qualifying Termination) (as defined below), Mr. Bell shall become a consultant to Interpublic for a period of five years (the "Consulting Period"). During the Consulting Period, Mr. Bell is required to make himself available, upon reasonable notice, to provide services that are commensurate with his years of experience and level of skill for up to ten full business days during any calendar quarter. As compensation for his consulting services, Mr. Bell will receive an annual consulting fee equal to 75% of the average of his annual base salary for the last three full calendar years of his employment ("Consulting Payments"). During the Consulting Period, stock option grants and restricted stock awards made to Mr. Bell prior to becoming a consultant will continue to vest. The Consulting Period will terminate and the Consulting Payments will immediately cease to be paid prior to the end of the five-year Consulting Period upon the material failure of Mr. Bell to perform the duties requested of him by Interpublic during the Consulting Period or upon a material breach by Mr. Bell of the employment agreement or other action by Mr. Bell that constitutes "cause", as defined below. If, however, Mr. Bell were to die or become permanently disabled during the Consulting Period, then his benefits would continue to be paid to him or to his estate, as applicable, for the remainder of the Consulting Period.

        If Mr. Bell's employment terminates prior to the expiration of the Employment Period under the circumstances constituting a Qualifying Termination, Mr. Bell, or his executor as the case may be, is entitled to receive the following benefits: (a) annual incentive compensation for the calendar year in which such termination occurs, prorated through the termination date (based on actual results for the full year); and (b) the right to exercise each stock option granted after January 1, 2001, to the extent that it is vested at the date of termination for up to three years after the date of termination but in no case beyond ten years following the date that the stock option was granted.

        If the Qualifying Termination is for any reason, other than death or disability, Mr. Bell also is entitled to: (a) receive for a period of three years (the "Severance Period") a cash severance of an amount equal to (i) his base salary at the rate payable to him on the date of his termination and (ii) the higher of the annual incentive compensation payable to Mr. Bell for the calendar year in which he is terminated or the average annual incentive during the three full calendar years prior to the year his employment is terminated; (b) the vesting of all stock options granted to Mr. Bell after January 1, 2001; and (c) receipt of Consulting Payments for a period of two years after the end of the Severance Period. Alternatively, if the Qualifying Termination is due to disability, Mr. Bell will be entitled to the receipt of Consulting Payments for a period of five years after the date of termination.

        A Qualifying Termination means the occurrence of any of the following events prior to the expiration of the Employment Period: (a) the termination of Mr. Bell's employment by Interpublic without "cause" (as defined below) where Interpublic does not either provide Mr. Bell with twelve months notice of termination or pay his salary for twelve months in lieu of such notice; (b) the termination by Mr. Bell of his employment due to the occurrence of any of the following events, without his written consent: (i) an assignment of duties that are inconsistent in any material respect with his position, duties, responsibilities or status or a material diminution in his responsibilities, (ii) a material adverse change in his reporting responsibilities, title or offices with Interpublic, (iii) a material breach by Interpublic of its obligations under the employment agreement, (iv) a decrease in his base salary, or (v) a material change in the location where he is based; (c) the disability of Mr. Bell for a period of more than six consecutive months; or (d) Mr. Bell's death.

        The employment agreement provides that Interpublic shall have "cause" to terminate Mr. Bell, if Mr. Bell: (a) engages in conduct that violates a material provision of the employment agreement or any significant policy of Interpublic after Mr. Bell is notified of such violations, (b) fails to perform his duties or carry out directions from the Board of Directors after being notified of such failure, or (c) engages in embezzlement or a misappropriation of corporate funds or other acts of fraud, dishonesty or self-dealing,

26


or commits a felony or any significant violation of any material statutory or common law duty of loyalty to Interpublic.

Brian Brooks' Separation Agreement

        Effective February 27, 2004, Mr. Brooks resigned from all positions that he held at Interpublic and its subsidiaries. In connection with his resignation, Mr. Brooks entered into a Confidential Separation Agreement and General Release with Interpublic (the "Separation Agreement") which provides that Interpublic will (a) as severance continue to make salary payments to Mr. Brooks for a period of one year ending February 27, 2005 (the "Severance Period") at his annual base salary of $495,000, and (b) retain Mr. Brooks to provide, as requested by Interpublic, executive recruiting and human resource services during the Severance Period and for a period of one year thereafter (the "Consulting Period"). Under the Separation Agreement, Mr. Brooks is entitled to compensation at an hourly rate of $400 per hour as consideration for services other than in connection with executive recruitment and at a commission of 25% of the first year's total cash compensation of salary and bonus not to exceed $500,000 per person of individuals placed at Interpublic or its subsidiaries as a result of Mr. Brooks' executive recruitment efforts. During the Severance Period, Mr. Brooks will be entitled to receive consultancy compensation to the extent such compensation is in excess of his base salary of $495,000, up to a total of $700,000. During the Consulting Period, Mr. Brooks will be entitled to receive a guaranteed minimum annual compensation of $400,000.

        The Separation Agreement also provides that during the Severance Period, Mr. Brooks (i) will continue to be entitled to his current employee benefits, including medical, life insurance, profit sharing, club, automobile and financial planning allowances, (ii) will remain eligible for a bonus for 2003 and (iii) will remain eligible for deferral amounts under Interpublic's Senior Executive Retirement Income Plan, which is described below under the heading "The Interpublic Senior Executive Retirement Income Plan".

        In addition, under the Separation Agreement, all shares of restricted stock granted to Mr. Brooks will continue to vest on a pro rata basis through the end of the Severance Period, and in the case of a November 10, 2003 award of 102,233 shares of restricted stock, the award will vest in full on January 31, 2008 if Mr. Brooks abides by a non-solicitation provision of the Separation Agreement through that date. All stock options granted to Mr. Brooks will continue to vest through the end of the Severance Period and, to the extent then exercisable, will remain exercisable for a 90-day period following the end of the Severance Period. At the end of the Severance Period, Mr. Brooks will be entitled to receive 3,611 performance units out of the 5,000 performance units originally granted to Mr. Brooks under Interpublic's LTPIP for the 2003-2005 performance period.

Executive Severance Agreements

        Interpublic has entered into an agreement with each of the named executive officers, other than Messrs. Bell and Wilmot, pursuant to which a cash severance payment would become payable to the executive individual if, within two years after a "change of control," (i) the executive's employment is terminated by Interpublic other than for "cause" or (ii) the executive's resigns for "good reason."

        The agreements provide that a "change of control" occurs if: (a) any person other than Interpublic or any of its subsidiaries, becomes the beneficial owner (within the meaning of Rule 13d-3 of the Securities Exchange Act of 1934, as amended) of 30% or more of the combined voting power of Interpublic's then outstanding voting securities; (b) the stockholders approve an agreement to merge or consolidate with another corporation (other than a subsidiary of Interpublic) or an agreement to sell or dispose of all or substantially all of the business or assets of Interpublic; or (c) during any period of two consecutive years, individuals who, at the beginning of such period, constituted the Board of Directors cease for any reason to constitute at least a majority thereof, unless the election or the nomination for election by Interpublic's

27


stockholders of each new director was approved by a vote of at least two-thirds of the directors then still in office who were directors at the beginning of the period.

        Under the agreements, Interpublic shall have "cause" to terminate an executive, following a "change of control", if the executive: (a) engages in conduct that constitutes a felony and that results in the personal enrichment of the executive at Interpublic's expense; (b) refuses to substantially perform his responsibilities for Interpublic; or (c) deliberately and materially breaches any agreement between himself and Interpublic and fails to remedy that breach within a 30-day cure period. An executive may resign for "good reason" following a "change in control" if, without his consent, in any circumstance other than his disability, his office in Interpublic or the geographical area of his employment should be changed or his compensation should not continue to be paid and increased on the same basis as had been in effect prior to the "change of control" or the individual should determine in good faith that Interpublic had, without his consent, effected a significant change in his status within, or the nature or scope of his duties or responsibilities with, Interpublic and Interpublic failed to cure such situation within 30 days after written notice from the individual.

        The severance payment to which an executive, other than Messrs. Camera and Krakowsky, would be entitled is equal to three times the individual's average annual compensation during the two calendar years ended prior to the date of a "change of control". Messrs. Camera and Krakowsky are entitled to receive two times such executive's average annual compensation. In addition, each executive is entitled to receive a partial annual bonus based on the most recent bonus paid to such executive within the two years preceding the year such executive is terminated prorated for the elapsed portion of the year in which employment terminated. In general, if no bonus was paid to an executive in such prior years, such executive would be entitled to a pro rata bonus based on the greater of the last bonus actually awarded to such executive and the target bonus award established for such executive. The average compensation used in calculating the severance payment would be the executive's taxable compensation plus any deferred compensation accrued during the two relevant years, but would not include any deferred compensation earned in prior years but paid during the two years and would not include any taxable compensation relating to any stock option or restricted stock plan of Interpublic.

        Each agreement also provides that if the executive's employment terminates in circumstances entitling him to a severance payment, he will, for a period of 18 months following the termination of his employment, neither (a) solicit any employee of Interpublic or any of its subsidiaries to leave such employ to enter into the employ of the individual, or any person or entity with which the individual is associated, nor (b) solicit or handle, on his own behalf or on behalf of any person or entity with which he is associated, the advertising, public relations, sales promotion or market research business of any advertiser which was a client of Interpublic or any of its subsidiaries on the date the individual's employment terminates.

        The agreements give the executive an option to limit payment under the agreements to such sum as would avoid subjecting the individual to the excise tax imposed by Section 4999 of the Internal Revenue Code.

        Also under the severance agreements, sums previously deferred by the executive pursuant to employment agreements and under the Management Incentive Compensation Plans of Interpublic and its subsidiaries and amounts payable under Special Deferred Benefit Agreements would become payable within 30 days following a "change of control" if the individual has elected to receive the distribution prior to the "change of control."

The Interpublic Senior Executive Retirement Income Plan

        Effective as of August 1, 2003, Interpublic established a new plan to provide U.S.-based senior executives of Interpublic and its subsidiaries with certain retirement benefits. This new plan is intended to replace Interpublic's prior program of providing Special Deferred Benefit Agreements to key executives. In general, under the Senior Executive Retirement Income Plan ("SERIP"), Interpublic will provide an

28


eligible participant with an annual payment for 15 years, payable when the participant attains the age of 60 or older and after the participant's employment has terminated with Interpublic or its subsidiaries. Under certain conditions, payments may begin as early as age 55 and may be paid over ten years. Each participant must execute a Participation Agreement that provides for the amount of the annual benefit to be paid. Any portion of a participant's benefit that is not vested will be forfeited upon termination of employment. Generally, the retirement benefit will begin to vest after three years of participation in the SERIP and will vest in full after ten years. Any participant who is a party to a Special Deferred Benefit Agreement at the time the participant begins to participate in the SERIP is deemed to have participated in the SERIP for up to three years. At the end of three years of participation in the SERIP, 30% of the annual benefit is vested, with the vested portion increasing by 10% for the next seven years.

        If a participant becomes disabled or dies, the participant (or the participant's beneficiary) may be entitled to a full or reduced annual benefit, depending upon his age and years of participation under the SERIP at the time his employment is terminated by reason of death or disability.

        Of the named executive officers, only Mr. Brooks participates in the SERIP. Under his Participation Agreement, Mr. Brooks' annual benefit is $247,500 per year which, in accordance with his Separation Agreement, will vest as to 40% of this amount at the end of his Severance Period. Consequently, Mr. Brooks will be entitled to receive an annual payment of $99,000 for 15 years beginning on his 60th birthday.

Retirement Plan

        As of January 1, 1992, Interpublic adopted the Interpublic Retirement Account Plan to provide benefits under a "cash balance formula" to employees of Interpublic and most of its domestic subsidiaries who have at least five years of service. Each year a participant's account balance is credited with an amount equal to a percentage of the participant's annual compensation and interest credits. The percentage of annual compensation varies based on the sum of the participant's age and years of service from 1.5% for participants with a sum less than 40 years to 5% for participants with a sum of 80 or more years. Interest credits are based on the 1-year U.S. Treasury bill rate plus 1 percentage point, compounded quarterly, and are guaranteed to be at least 5% per year, compounded quarterly.

        Until July 31, 1987, employees of Interpublic and most of its domestic subsidiaries were entitled in general to receive at retirement a monthly retirement benefit pursuant to a defined benefit pension formula computed as a percentage of average monthly compensation during the five consecutive calendar years with highest compensation with certain exclusions. The percentage of average monthly compensation used to calculate the monthly benefit was determined by multiplying the number of years of accredited service (which is defined in the Plan as the period of participation in the Plan) by 1.3%.

        Beginning July 31, 1987, the method of calculating the pension benefit was changed to a career average formula based on annual compensation. The percentage of annual compensation used to calculate the benefit was 1% of each year's compensation up to $15,000 plus 1.3% of any compensation in excess of that amount.

        Participants under the defined benefit pension formula on December 31, 1991, had their normal retirement benefit converted on an actuarial basis into an "opening cash balance" as of January 1, 1992. In addition, participants continued to accrue benefits pursuant to the career average formula and became eligible to receive upon retirement the higher of (1) the participant's benefit under the cash balance formula or (2) the participant's accrued retirement benefit under the career average formula as of December 31, 1991, plus any accrual after that date calculated pursuant to the career average formula. Employees joining Interpublic after December 31, 1991, were eligible to accrue benefits only under the cash balance formula.

29


        With certain minor exceptions, "compensation" under the career average formula as well as the cash balance formula includes all compensation subject to federal income tax withholding. Annual compensation for pension accruals since December 31, 1988 has been limited by federal tax law.

        As of March 31, 1998, Interpublic froze benefit accruals under the Interpublic Retirement Account Plan and participants whose benefits were not already vested became fully vested as of April 1, 1998. Retirement account balances as of that date will continue to be credited with interest until benefits begin in accordance with the generally applicable Plan provisions, but additional Company allocations have been discontinued as of March 31, 1998.

        Effective April 1, 1998, employees with five or more years of Retirement Account Plan participation began to participate in a new Compensation Plan. Under the new Compensation Plan, an account is established for each eligible employee and credited with up to ten annual allocations depending on the employee's years of participation in the Retirement Account Plan. Each annual allocation approximates the discontinued allocations under the Retirement Account Plan. In general, the balance in each employee's account begins to vest gradually after five years of participation in the new Compensation Plan. Payouts generally are made while the employee is still employed by Interpublic or one of its subsidiaries.

        The estimated annual retirement benefit that each of the following named executive officers would receive at the normal retirement age of 65 years old, payable as a straight life annuity under the Interpublic Retirement Account Plan is as follows: Mr. Camera—$3,519; Mr. Dooner—$62,185; Mr. Nelson—$58,259 and Mr. Wilmot—$37,447. Alternatively, each of them could take the benefit as a lump sum estimated as follows: Mr. Camera—$40,699; Mr. Dooner—$735,889; Mr. Nelson—$689,431 and Mr. Wilmot—$442,205.

        Prior to normal retirement age, under the New Compensation Plan, Mr. Dooner will receive a total distribution of $108,500.

        Prior to normal retirement age, under the New Compensation Plan, Mr. Wilmot will receive a total distribution of $97,441.

        Mr. Camera is not eligible to participate under the New Compensation Plan because he had less than five years of participation under the Interpublic Retirement Account Plan at the time benefit accruals were frozen.

        Mr. Nelson is ineligible to participate under the New Compensation Plan because he was not employed with Interpublic at the time the New Compensation Plan became effective.

        Each of Messrs. Bell, Brooks, Coughlin and Krakowsky is not entitled to receive benefits under the Interpublic Retirement Account Plan or the New Compensation Plan because he was hired by Interpublic after the Retirement Account Plan was frozen.

REPORT OF THE COMPENSATION COMMITTEE OF THE BOARD OF DIRECTORS

The Committee's Responsibilities

        The Compensation Committee of the Board is responsible for setting and administering the policies that govern executive compensation. The Committee is composed entirely of independent, non-employee directors, based on the New York Stock Exchange Listing Standards. Reports of the Committee's actions and recommendations are presented to the full Board and independent directors who are not Committee members will, on occasion, attend and participate in Committee meetings. The purpose of this report is to summarize the philosophical principles, specific program elements and other factors considered by the Committee in making decisions about executive compensation.

        The Committee approves all of the policies under which compensation is paid or awarded to Interpublic's executives, and individually reviews the performance of, and all compensation actions pertaining to, Interpublic's senior executive group. The Committee has delegated to the Management Human Resources Committee, consisting of Interpublic's Chairman, President and CEO, its COO and CFO, its General Counsel, and its Chief Talent and Human Resources Officer, responsibility for the review of the performance of, and compensation actions affecting, a broader management group based on guidelines established by the Compensation Committee. Both the Compensation Committee and the Management Human Resources Committee use qualified outside advisers to assist in making pay practice decisions.

        The Committee's basic goal in establishing compensation guidelines is to attract, motivate, reward and retain executives who contribute to the creation of long-term investor value. The Committee adheres to the following principles when making compensation decisions:

Program Elements

        Interpublic's executive compensation program consists of base salary, annual incentive and long-term incentive compensation. Incentive opportunities are weighted toward the long-term for Interpublic's most senior executives and a major portion of long-term incentives are equity-oriented. Interpublic's

31


shareholder-approved 2002 Performance Incentive Plan, provides for equity and cash incentive awards under one or more of the following programs:

        The determination of the amount and form of executive compensation, including incentive compensation, paid to each Interpublic executive officer is made by the Committee based on an evaluation, after taking into account a range of factors that include:

        Although the Committee does not assign a pre-determined weight to any of these factors, its compensation decisions are greatly influenced by Interpublic's annual financial performance.

        During 2003, the Committee retained the services of an independent executive compensation firm to review the competitive pay positioning for approximately 40 senior corporate and operating company positions. The consultants' analyses and findings were presented to the Committee in November 2003. During the course of 2003, these and other consultants provided the Committee with data, findings and/or recommendations related to executive compensation, benefits, and other related topics. The Committee considered this input in its deliberations.

2003 Compensation of Executive Officers

        Base Salary.    Salary increases for executive officers are based on individual performance, role and responsibilities, competitive labor market conditions, and Interpublic's overall financial results. Base salaries for executive officers and other senior executives of Interpublic are established by reference to the factors noted above and with the advice of outside compensation consultants. The Compensation Committee has established a policy of setting base salary levels within 15% above or below mid-market levels for comparable positions in the marketing communications industry. The salaries of executive officers continuing to serve in the same position are generally reviewed every two years.

        Annual Incentive.    For purposes of bonus awards under the MICP, the executive officers of Interpublic participate in the Interpublic corporate bonus pool, unless they are employed by one of Interpublic's operating units, in which case they participate in that operating subsidiary's MICP bonus pool. Under the terms of the MICP, the corporate bonus pool may not exceed 5% of the amount by which consolidated pre-tax income on a worldwide basis, and before provision for the payment of incentive compensation, for the calendar year in which the bonuses are to be paid exceeds 15% of the average equity capital of Interpublic in the immediately preceding calendar year. In 2003, due in part to substantial restructuring, litigation, and asset impairment charges, Interpublic incurred a pre-tax loss, and as a consequence under the terms of the MICP no funds were available for the payment of incentive awards from the corporate bonus pool. After not making MICP awards to executive officers in 2002, and recognizing the significant progress made in 2003 in implementing of the company's turnaround plan, the Committee concluded that it was necessary to acknowledge and reward the participants in the corporate bonus pool who made this progress possible. Accordingly, the Committee authorized a waiver for 2003 of the earnings requirement for funding of the corporate bonus pool and approved a corporate bonus pool in the aggregate amount of $6.3 million. The 2003 bonus pools of the operating units reflected each unit's specific operating results and progress toward improving future operating performance. Bonus awards to executive officers in 2003 were generally made at 75% of target, with this percentage varying among individuals based on relative contribution to Interpublic's ongoing financial and operating turnaround.

        Long-term Incentives.    In 2003, the Committee made both long-term incentive awards to executive officers and key employees of Interpublic and its subsidiaries in the form of cash-based LTPIP awards and equity grants and also cancelled or modified LTPIP awards made in 2003.

        LTPIP Awards.    In early 2003, the Committee cancelled the 2002-2004 LTPIP units granted Corporate Participants due to the financial performance of Interpublic, which indicated that no payout under the awards was likely.

        In March 2003, new grants of performance units under the LTPIP for the 2003-2005 performance period were made to executive officers including those listed in the Long-Term Incentive Plan Table. In determining individual LTPIP awards to executive officers, the Committee considered several factors including, but not limited to, the executive's recent performance and expected future contributions, current role and responsibilities, and history of past grants. However, in December 2003, the Committee decided to terminate the LTPIP because it has determined that it no longer meets the Committee's goal of more closely aligning executive incentives with shareholder interests. Accordingly, no future awards will be made under the LTPIP. In addition, due to Interpublic's financial performance during 2003, it became apparent to the Committee that the performance goals of Interpublic and its operating units as contemplated by the terms of the 2003-2005 awards would not be achieved. The Committee, therefore, in order to prepare for the implementations of a new incentive compensation program elected to determine the payouts under the awards in advance of the completion of the performance period in the following manner:

33

        In connection with the Committee's decision to discontinue the LTPIP, the Committee also decided to shorten by one year the 2002-2004 LTPIP performance period for operating division participants. For such participants, 2002-2004 LTPIP units have been valued using the 2002 and 2003 actual results of the applicable operating division. Awards will be paid as originally scheduled: (i) one-half of the award in early 2004 and (ii) the remaining one-half in early 2005.

        Equity Grants.    In 2003, the Committee provided officers and key employees of Interpublic and its subsidiaries with a long-term incentive opportunity in the form of stock options and/or restricted stock awards. Such awards are designed to focus the recipients on the long-term performance of Interpublic. Stock options are granted on such terms as are approved by the Committee, provided that the term of the option may not exceed ten years and the exercise price may not be less than the fair market price of the Common Stock on the date of grant. The majority of stock options granted in 2003, and all options granted to executive officers in 2003, vest in increments of one-third on the second, third and fourth anniversaries of the date of grant. Grants to the named executive officers are shown in the preceding tables.

        The sale or transfer of shares granted as restricted stock are typically restricted for a period of three to five years from date of grant and are forfeited if the executive should leave the employment of Interpublic before the restrictions expire, unless the Committee determines otherwise.

        In determining grants of stock options and restricted stock, the Committee considers the executive's current total compensation, recent performance, expected future contributions and impact on shareholder value, equity grant history, and potential retention risk; competitive need to provide equity-based compensation to a given position; and Interpublic's financial performance in terms of operating margin, revenue and operating income growth, and total shareholder return. The Committee also reviews outside survey data describing the equity grant practices within Interpublic's relevant labor markets, including by other companies having similar business interests, capitalization and scope of operations to those of Interpublic (including some companies included in the Peer Group Index appearing in the performance graph that follows this Report).

Compensation of Chief Executive Officer

        Mr. Bell assumed the role of Chairman, President and Chief Executive Officer, and became a member of the Board of Directors on February 27, 2003, at which time Mr. Dooner assumed the role of Chairman and Chief Executive Officer of McCann-Erickson WorldGroup.

        At the time of his promotion, the Committee reviewed Mr. Bell's compensation and that for his industry peers. The Committee decided not to adjust his base salary and it remained at $1,000,000 for the year. To secure his services in his new role, the Committee elected to provide Mr. Bell with a $100,000 signing bonus, 20,000 LTPIP units for the 2003-2005 performance period and 200,000 stock options. In addition, Mr. Bell entered into a special deferred benefit agreement under which he elected to forego $150,000 of salary per year for 8 years to fund a retirement benefit payable over 15 years. See "Employment Agreements, Termination of Employment and Change-in-Control Arrangements—Deferred Benefit Arrangements—Special Deferred Benefit Agreements".

        In 2003, Mr. Bell received an MICP award in the amount of $1,200,000, representing 78% of his target award. Mr. Bell's performance goals in 2003 included improving Interpublic's balance sheet, developing a long-term strategy for Interpublic and improved financial performance. In determining the payout amount,

34


the Committee also gave considerable weight to the circumstances under which he assumed the Chairman and CEO role at the end of February. Under the leadership of Mr. Bell, Interpublic began a turnaround in 2003 and achieved the following:

        In 2002, Mr. Bell received a 2002-2004 LTPIP grant of 5,000 units tied to the performance of Interpublic's Foote, Cone & Belding division. As discussed above, the 2002-2004 performance period for awards to operating division employees has been shortened by one year, with the value of the units based on the actual performance of the applicable division for the years 2002 and 2003. Based on the results of Foote, Cone & Belding, Mr. Bell's 2002-2004 units were valued at $0, and accordingly he will not receive a payment. A 2002-2004 LTPIP grant of 5,000 units tied to the financial performance of Interpublic, like those of other executives, was cancelled.

        In conjunction with his promotion, Mr. Bell received 20,000 units under the LTPIP for the 2003-2005 performance period tied to Interpublic performance, each with a target value of $115. As discussed above, when the Committee decided to terminate the LTPIP program, it elected to fix the payouts with respect to the 2003-2005 performance period in advance of the completion of the performance period at a value of $38.33 per unit. As a result, Mr. Bell will receive a payment of $255,533 representing one-third of the award in early 2005, and a payment of $511,067, representing the remaining two-thirds will be paid in early 2006.

        The 200,000 stock options awarded to Mr. Bell have an exercise price of $9.64 per share, based on the average of the high and low market prices of Interpublic Common Stock on the March 26, 2003 grant date and will become exercisable 33%, 33% and 34% after two, three and four years, respectively, from date of grant. The Committee's objective in awarding Mr. Bell this grant of stock options, was to begin to bring Mr. Bell's compensation up to external competitive practices and levels among other marketing communications companies.

        Mr. Dooner's compensation during 2003 consisted of a cash salary of $1,250,000 per year as specified in his Employment Agreement. Mr. Dooner also received a grant of 176,709 stock options with an exercise price of $9.64 per share, based on the average of the high and low market prices of Interpublic Common Stock on the March 26, 2003 grant date. The options will become exercisable 33%, 33% and 34% after two, three and four years, respectively, from date of grant. The Committee's objective in awarding Mr. Dooner this grant of stock options, was to secure Mr. Dooner's services in leading the McCann-Erickson WorldGroup turnaround amid ongoing concerns that Mr. Dooner could be lured away with sizable option grants from other companies. Mr. Dooner also received an LTPIP grant of 20,000 performance units for the 2003-2005 performance period linked to McCann-Erickson WorldGroup performance. After giving effect to the shortened performance period, as described above, this grant had no value based on 2003 actual results and 2004 budgeted performance. Therefore, Mr. Dooner will not receive any payment under the 2003-2005 performance period. A 2002-2004 LTPIP grant of 20,000 units tied to the financial performance of Interpublic like those of other executives, was cancelled.

        Finally, the Committee elected to pay Mr. Dooner an MICP award of $750,000, or 45% of his target, to reflect its balanced assessment of his performance, including consideration of the improvement in McCann-Erickson's operating results under his direction, his mid-year reduction in responsibilities and its belief that stronger performance would be required to warrant an award closer to or above target.

2004 Performance Incentive Plan

        At the 2004 Annual Meeting, shareholders will be asked to consider the proposed 2004 Performance Incentive Plan, which, if approved by shareholders, will replace the 2002 Performance Incentive Plan. The purpose of the new plan is to facilitate a shift in Interpublic's long-term incentive compensation practices from an emphasis on cash awards and stock options to focus more heavily on restricted stock awards, particularly restricted stock awards the receipt of which is tied to future performance. For a description of the 2004 Performance Incentive Plan, please refer to the discussion in the proxy statement under the heading "Proposal to Adopt the 2004 Performance Incentive Plan" and the text of the new plan, which is attached as Appendix B.

Deductibility of Executive Compensation

        Under federal income tax laws, the deduction that a publicly-held company is allowed for compensation paid to its chief executive officer and to its other four most highly compensated executive officers generally is limited to $1 million exclusive of qualifying performance-based compensation. The Committee has and will continue to consider ways to maximize the deductibility of executive compensation, including the utilization of performance-based plans, while retaining the discretion the Committee deems necessary to compensate executive officers in a manner commensurate with performance and the competitive environment for executive talent. The 2002 Performance Incentive Plan and the proposed 2004 Performance Incentive Plan each contain provisions relating to MICP awards, stock option grants and performance units that are intended to make the awards eligible for exclusion from the $1 million limitation. Due to the waiver of the earnings requirement for the funding of the Interpublic corporate bonus pool, the 2003 MICP payments to Interpublic's executive officers will not qualify as performance-based compensation. The aggregate amount of such disqualified MICP compensation, which is payable in 2004, cannot exceed, but likely will be less than, $3.4 million. Likewise, due to the modifications of the terms of the LTPIP awards for the 2003-2005 performance period, as described above, none of the payments pursuant to such awards to Interpublic's executive officers will qualify as performance-based compensation. The aggregate amount of such disqualified LTPIP compensation cannot exceed, but likely will be less than, $0.5 million in 2005 and $1.1 in 2006.

Conclusion

        The Committee is satisfied that the compensation and long-term incentive plans provided to executives of Interpublic foster a performance-oriented culture and create strong alignment with the long-term best interests of Interpublic's shareholders. The Committee is further satisfied that the compensation levels are reasonable in light of performance, industry practice and, in isolated cases, historical practice. Finally, the Committee will continue in its search to further tighten the relationship between pay and meaningful performance.

2. PROPOSAL TO ADOPT THE 2004 PERFORMANCE INCENTIVE PLAN

        The Board of Directors has adopted, and is submitting to stockholders for approval, The Interpublic Group of Companies, Inc. 2004 Performance Incentive Plan (the "Plan").

Background

        At the 2002 Annual Meeting, the stockholders of Interpublic approved The Interpublic Group of Companies, Inc. 2002 Performance Incentive Plan (the "2002 Plan"). Under the 2002 Plan a maximum of 12.5 million shares of Common Stock were reserved for issuance, of which approximately 2.6 million shares (net of the addition of shares surrendered or forfeited under the 2002 Plan and prior plans) have been issued or are reserved for issuance pursuant to outstanding awards, leaving approximately 9.9 million shares of Common Stock available for future awards. If the Plan is approved by stockholders at the Annual Meeting, no further awards will be made under the 2002 Plan.

        In recent years, Interpublic's long-term incentive awards under the 2002 Plan have consisted primarily of cash awards based on performance over a three-year period and stock options. Based on a reevaluation of Interpublic's incentive compensation practices, the Board of Directors has determined such cash-based awards are not adequately tailored to the goal of closely aligning Interpublic's long-term incentive arrangements with the interests of the company's stockholders and that stock option awards raise accounting issues and stockholder dilution concerns. Accordingly, the Board of Directors believes that it is in the best interests of Interpublic and its stockholders to focus more heavily on restricted stock awards, particularly restricted stock awards the receipt of which is tied to future performance, as the company's primary form of long-term incentive compensation. The Plan is designed to facilitate this change in Interpublic's incentive compensation objectives.

        Among the key features of the Plan, which the Board of Directors believes reflect Interpublic's strong commitment to sound compensation and governance practices, are the following:

38

        While future needs will depend on actual grant practices, potential future hires and the price of the Common Stock, the Board of Directors currently believes that the shares of Common Stock authorized for issuance under the Plan will be sufficient to meet the company's incentive compensation needs for at least a three-year period.

        If the Plan is approved by stockholders, the Board of Directors currently anticipates that restricted stock awards under the Plan in 2004 will predominantly have service-based vesting provisions. However, the Board of Directors expects that in future years the Compensation Committee will place increasing emphasis on restricted stock awards that vest only if pre-established performance criteria are satisfied.

Description of the Plan

        The text of the Plan is attached hereto as Appendix B and is hereby incorporated by reference. The following description of the Plan is qualified in its entirety by reference to the text of the Plan.

Purposes of the Plan

        The purposes of the Plan are to promote the interests of Interpublic by enabling Interpublic to:

Administration

        The term of the Plan requires that it be administered by a committee (the "Committee") appointed by the Board of Directors that satisfies the requirements of Rule 16b-3 under the Securities Exchange Act of 1934, as amended (the "Exchange Act"). Under Rule 16b-3, the committee responsible for the administration of the plan must be composed solely of two or more members of the Board of Directors who are not employees of Interpublic and who do not have any other disqualifying affiliations with Interpublic. The Board of Directors has assigned the responsibility for the administration of the Plan to the Compensation Committee.

        If the Committee deems it advisable, it may delegate its authority under the Plan to the extent permitted by applicable law to one or more of its members or to one or more persons other than its members, except that no such delegation of authority is permitted with respect to the participation in the Plan of persons who are subject to Section 16 of the Exchange Act. No member of the Committee is eligible to receive an award under the Plan.

Eligibility

        Any employee of Interpublic, or any of its subsidiaries or affiliates (defined generally to include any corporation or other entity in which Interpublic directly or indirectly owns at least a 40% interest), that the Committee determines to be responsible for, or able to contribute to, the growth, profitability, and success of Interpublic is eligible to participate in the Plan. Approximately 5,600 employees of Interpublic and its subsidiaries and affiliates will be eligible to participate in the Plan. Directors who are not employees of Interpublic or any of its subsidiaries or affiliates are not eligible to participate in the Plan.

39


Shares Available for Awards

        Under the Plan:

        In determining at any time the number of shares of Common Stock available in the respective share pools for future awards under the Plan, the following rules will apply:

In addition, any shares of Common Stock underlying awards granted in assumption of, or in substitution for, outstanding awards previously granted by a company acquired by Interpublic or one of its subsidiaries or affiliates or with which Interpublic or one of its subsidiaries or affiliates combines, will not, unless required by law or regulation, be counted against the number of shares of Common Stock available for awards under the Plan.

        The shares of Common Stock issuable under the Plan may be either authorized but unissued shares or shares held in treasury and not reserved for some other purpose.

Types of Awards

        The following types of awards may be made to eligible employees under the Plan:

        The selection of employees to receive awards, the type and amount of an award, and the terms and conditions of an award all are matters that are determined in the sole discretion of the Committee.

        Stock Options    Stock options granted under the Plan may be either incentive stock options ("ISOs") that are intended to satisfy the requirements of Section 422 of the Internal Revenue Code of 1986, as amended (the "Code"), or options that are not intended to meet such requirements ("nonstatutory stock options"). No participant may receive stock options with respect to more than 500,000 shares of Common Stock in any calendar year. The Plan prohibits the Committee from granting any stock option with a so-called "reload" feature (under which the holder of a stock option is automatically granted additional stock

40


options to the extent the holder tenders shares of Common Stock in payment of the exercise price of the stock option or to satisfy tax withholding obligations associated with the exercise).

        The exercise price of a stock option may not be less than 100% of the fair market value of the Common Stock on the date of the grant and the term of a stock option may not be longer than 10 years. Each stock option may be exercised at such times and subject to such terms and conditions as the Committee may specify at the time of the grant or thereafter; provided that, except in the event of the retirement, death or disability of the holder or upon the occurrence of a "change of control" (as hereinafter defined), a stock option may not be exercised in whole or in part during the twelve-month period following the grant. Payment of the exercise price of a stock option may be made (i) in cash or its equivalent, (ii) if and to the extent permitted by the Committee, by the delivery of or attestation to the ownership of shares of Common Stock that have been owned by the optionholder without restriction for a period of at least six months, or (iii) by a combination of the foregoing. The Plan prohibits the Committee form authorizing a loan to a holder of a stock option for the purpose of enabling the holder to pay all or any portion of the option exercise price or the associated tax withholding obligations.

        Restricted Stock    Restricted stock is Common Stock that is granted to an employee that will become vested, and therefore nonforfeitable, upon the satisfaction of such terms and conditions as the Committee may determine. Vesting may be employment-based, performance-based, or both. Employment-based awards of restricted stock vest if the holder completes a period of employment designated by the Committee. Performance-based awards of restricted stock vest to the extent that performance objectives established by the Committee are attained.

        The performance criteria selected by the Committee for performance-based awards of restricted stock must be based on one or more of the following criteria:

The foregoing performance criteria may relate to the performance of (i) Interpublic, (ii) a subsidiary of Interpublic, (iii) an affiliate of Interpublic, (iv) a division or unit of Interpublic or any subsidiary or any affiliate of Interpublic, (v) an office, group of agencies, or all or part of any agency system of Interpublic, (vi) the recipient of the award, or (vii) any combination of the foregoing, over a period established by the Committee, as measured either in absolute terms or in comparison with the performance of other companies.

        In any calendar year, no participant may be granted performance-based awards of restricted stock and restricted stock units relating in the aggregate to more than 300,000 shares of Common Stock.

        Until such time as the restrictions imposed by the Committee lapse (the "restricted period"), shares of restricted stock may not be sold, assigned, transferred, pledged, hypothecated, or otherwise disposed of by the holder. Except in the event of the retirement, death or disability of the holder or upon the occurrence of a "change of control", the restricted period may not be less than one year. Subject to such terms,

41


conditions, and restrictions as may be imposed by the Committee, the holder, during the restricted period, otherwise has absolute ownership of the restricted shares, including the right to vote and receive dividends on the shares. A holder of restricted stock may irrevocably elect to have any withholding tax obligation associated with the lapse of restrictions on restricted stock satisfied by (i) having Interpublic withhold shares of restricted stock otherwise deliverable to the participant or (ii) delivering to Interpublic such restricted stock or other shares of Common Stock; provided that the Committee may, in its discretion, disapprove any such election.

        Restricted Stock Units    A restricted stock unit is a contractual right to receive a payment, in cash or in shares of common stock, as determined by the Committee that is based on the fair market value of a share of common stock and that becomes vested and nonforfeitable in whole or in part, upon the attainment of conditions established by the Committee. Vesting may be employment-based, performance-based, or both. Employment-based awards of restricted stock units vest if the holder completes a period of employment designated by the Committee. Performance-based awards of restricted stock units vest to the extent that performance objectives established by the Committee are attained. The performance criteria that may be selected by the Committee for performance-based awards of restricted stock units are the same as those described above with respect to the vesting of performance-based restricted stock awards.

        In any calendar year, no participant may be granted performance-based awards of restricted stock and restricted stock units relating in the aggregate to more than 300,000 shares of Common Stock.

        Restricted stock units may not be sold, assigned, transferred, pledged, hypothecated, or otherwise disposed of by the holder at any time. Except in the event of the retirement, death or disability of the holder or upon the occurrence of a "change of control", the restricted period may not be less than one year. The holder of a restricted stock unit has no ownership interest in the shares of Common Stock to which the restricted stock unit relates unless and until a payment in respect thereof is made in shares of Common Stock.

        Performance Units    Performance units represent a contractual right of the holder to receive a payment that becomes vested upon the attainment of performance objectives established by the Committee relating to one or more of the same criteria described above with respect to the vesting of performance-based restricted stock awards. The number of performance units granted to an employee, the applicable performance objectives, the performance period and all other terms and conditions of a performance unit are determined in the discretion of the Committee. Performance units may be settled in cash, in shares of Common Stock or a combination of cash and shares, as determined by the Committee. The maximum amount that may be paid to a holder with respect to a performance unit award for any three-year performance period is $4 million. If the performance period is longer or shorter than three years, this limit is subject to proportionate increase or reduction to reflect the length of the performance period. No employee may participate in more than three performance periods at one time.

Management Incentive Compensation Performance Awards

        Under the management incentive compensation performance award component of the Plan, the Committee in its sole discretion is authorized to make management incentive compensation awards ("MICP awards") to employees of Interpublic and its subsidiaries and affiliates, subject to the limitation that no single individual is permitted to receive in any calendar year an award in excess of $5 million (prorated to reflect the length of the period for which the MICP award is granted). The amount of any MICP awards is determined by the Committee and is contingent upon the achievement of performance objectives relating to one or more of the performance criteria that are the same as those described above with respect to the vesting of performance-based restricted stock awards.

        MICP awards may be made in cash, shares of Common Stock, or a combination of cash and shares. The Committee in its discretion may direct that up to 75% of an individual's MICP award may be paid on a deferred basis, subject to such terms and conditions as the Committee may prescribe.

42


        Shares in Lieu of Cash    The Committee may award shares of Common Stock in lieu of all or part of any compensation that otherwise is payable in cash to an employee by Interpublic or any of its subsidiaries or affiliates. If shares of Common Stock are issued in lieu of cash, the number of shares to be issued must have a fair market value equal to or less than the amount of cash otherwise payable.

        Dividend Equivalents    Dividend equivalents represent the right to receive a payment equal to the aggregate dividend payment on a corresponding number of shares of Common Stock, and may be paid in cash, shares of Common Stock, or a combination of cash and shares. In connection with any award under the Plan, the Committee in its discretion may grant dividend equivalents, which may be paid on a current, deferred, or contingent basis.

Foreign Benefits

        The Committee may grant awards to employees of Interpublic and its subsidiaries and affiliates who reside in jurisdictions outside the United States. The Committee may adopt such supplements to the Plan as may be necessary to comply with applicable laws of such jurisdictions and to afford participants favorable treatment under such laws; provided that no award may be granted under any such supplement on the basis of terms or conditions that are inconsistent with provisions of the Plan.

Termination of Employment

        If the employment of the holder of an award terminates for any reason, any nonvested portion of the award will be forfeited, unless the Committee in its sole discretion determines otherwise, except that only in the case of the retirement, death or disability of the holder may the Committee allow an award to become vested prior to the first anniversary of the grant.

Nontransferability

        Unless the Committee shall permit (on such terms and conditions as it shall establish) an award to be transferred to a member of a participant's immediate family or to a trust, partnership, corporation, or similar vehicle, the parties in interest in which are limited to the participant and members of the participant's immediate family, no award may be assignable or transferable except by will or by the laws of descent and distribution.

Change of Control

        Upon the occurrence of a "change of control" all awards then outstanding will immediately become fully vested. A change of control is defined by the Plan to mean the occurrence of any of the following events: (i) any person (within the meaning of Sections 13(d) and 14(d) of the Exchange Act), other than Interpublic or any of its subsidiaries, becomes the beneficial owner (within the meaning of Rule 13d-3 under the Exchange Act) of 30% or more of the combined voting power of Interpublic's then outstanding voting securities, (ii) a tender offer or exchange offer (other than an offer by Interpublic), pursuant to which 20% or more of the then outstanding shares of Common Stock were purchased, expires, (iii) the stockholders of Interpublic approve an agreement to merge or consolidate with another corporation and the surviving corporation is neither Interpublic nor a corporation that was, prior to the merger or consolidation, a subsidiary of Interpublic, (iv) the stockholders approve an agreement (including a plan of liquidation) to sell or otherwise to dispose of all or substantially all of Interpublic's assets, or (v) during any period of two consecutive years, individuals who, at the beginning of such period, constituted the Board cease for any reason to constitute at least a majority thereof, unless the election or the nomination for the election by Interpublic's stockholders of each new director was approved by a vote of at least two-thirds of the directors then still in office who were directors at the beginning of the period or who were elected by directors who were directors at the beginning of the period.

43

Adjustments

        If the Committee at any time determines that a "corporate transaction" has occurred that affects the Common Stock such that an adjustment is required to preserve, or to prevent enlargement of, the benefits or potential benefits available under the Plan, the Committee may, in such manner as the Committee deems equitable, adjust any or all of (i) the number and kind of shares that thereafter may be made the subject of awards, (ii) the number and kind of shares that are subject to outstanding awards, and (iii) the grant, exercise, or conversion price of any award. In addition, the Committee may make provisions for a cash payment to a participant or other person holding an outstanding award. A "corporate transaction" is defined by the Plan to mean any stock split, stock dividend, extraordinary cash dividend, recapitalization, reorganization, merger, consolidation, split-up, spin-off, combination, exchange of shares, warrants or rights offering to purchase Common Stock at a price substantially below fair market value, or other similar event.

Repricing of Options

        Except adjustments to preserve, or prevent the enlargement of, benefits of a participant in the Plan in connection with a corporate transaction (as defined above), the Committee is not permitted to reprice stock options without the approval of Interpublic's shareholders.

Amendment of the Plan

        The Board of Directors or the Committee may amend, suspend, or terminate the Plan, or any portion thereof, at any time; provided that no amendment may be made without shareholder approval if (i) shareholder approval is required by law, regulation or stock exchange listing requirement or (ii) if the amendment would increase the number of shares of Common Stock available for awards under the Plan, other than in connection with a corporate transaction as described above. Without the written consent of an affected participant, no termination, suspension, or modification of the Plan may adversely affect any right of such participant under the terms of an award granted before the date of such termination, suspension, or modification.

Use of Proceeds

        All proceeds received by Interpublic from the sale of shares of Common Stock under the Plan will be used for general corporate purposes.

Effective Date and Duration of the Plan

        The Plan will become effective on the date that it is approved by Interpublic's stockholders. No awards may be granted under the Plan after the annual meeting of Interpublic's stockholders in 2010. Upon stockholder approval of the Plan, no further awards may be made under the 2002 Plan.

Federal Income Tax Consequences

        The material federal income tax consequences of awards under the Plan, based on the current provisions of the Internal Revenue Code and the regulations thereunder, are as follows:

        The grant of an option to an employee will have no tax consequences to the employee or to Interpublic or its subsidiaries or affiliates. In general, upon the exercise of an ISO, the employee will not recognize income, and the employer will not be entitled to a tax deduction. However, the excess of the acquired shares' fair market value on the exercise date over the exercise price is included in the employee's income for purposes of the alternative minimum tax. When an employee disposes of ISO shares, the difference between the exercise price and the amount realized by the employee will, in general, constitute capital gain or loss, as the case may be. However, if the employee fails to hold the ISO shares for more than one year after exercising the ISO and for more than two years after the grant of the ISO, the portion of any gain realized by the employee upon the disposition of the shares that does not exceed the excess of

44


the fair market value of the shares on the exercise date over the exercise price generally will be treated as ordinary income, the balance of any gain or any loss will be treated as a capital gain or loss, and the employer generally will be entitled to a tax deduction equal to the amount of ordinary income recognized by the employee. If an employee exercises an ISO, but fails to remain employed by Interpublic (or a subsidiary in which Interpublic holds at least 50% of the voting power) from the date of grant until three months preceding the date of exercise (one year preceding the date of exercise if the employee's employment terminated due to disability), the option will be treated for tax purposes as a nonstatutory stock option, as described below.

        In general, upon the exercise of a nonstatutory stock option, the employee will recognize ordinary income equal to the excess of the acquired shares' fair market value on the exercise date over the exercise price, and the employer generally will be entitled to a tax deduction in the same amount.

        With respect to other awards that are settled either in cash or in shares that are transferable or are not subject to a substantial risk of forfeiture, the employee will recognize ordinary income equal to the excess of (a) the cash or the fair market value of any shares received (determined as of the date of settlement) over (b) the amount, if any, paid for the shares by the employee, and the employer generally will be entitled to a tax deduction in the same amount.

        In the case of an award to an employee that is settled in shares that are nontransferable and subject to a substantial risk of forfeiture, the employee generally will recognize ordinary income equal to the excess of (a) the fair market value of the shares received (determined as of the date on which the shares become transferable or not subject to a substantial risk of forfeiture, whichever occurs first) over (b) the amount, if any, paid for the shares by the employee, and the employer generally will be entitled to a tax deduction in the same amount.

        An employee whose shares are both nontransferable and subject to a substantial risk of forfeiture may elect to recognize income when the shares are received, rather than upon the expiration of the transfer restriction or risk of forfeiture. If an employee makes this election, the amount of ordinary income, and the amount of the employer's tax deduction, are determined as of the date of receipt, rather than upon the expiration of the applicable restrictions.

        When an employee sells any shares acquired under a nonqualified stock option or any other award other than an ISO, the employee will recognize capital gain or loss equal to the difference between the amount realized on the disposition of the shares and the employee's basis in the shares. In general, the employee's basis in any such shares will be equal to the amount of ordinary income recognized in connection with the receipt of the shares plus any amount paid for the shares.

        When a cash payment is made to an employee, the employee will recognize the amount of the cash payment as ordinary income, and the employer generally will be entitled to a tax deduction in the same amount.

        In general, a corporation is denied a deduction for any compensation paid to its chief executive officer or to any of its four most highly compensated officers (other than the chief executive officer) to the extent that the compensation paid to the officer exceeds $1,000,000 in any year. "Performance-based compensation" is not subject to this deduction limit. The Plan permits the grant of both awards that qualify as performance-based compensation, such as options, performance-based restricted stock and restricted stock units, performance units and incentive compensation awards, and awards that do not so qualify, such as restricted stock and restricted stock units that are not performance-based, awards of shares of Common Stock in lieu of cash, and dividend equivalents.

        Any acceleration, vesting, or increase in the amount of an award under the Plan as a result of a change of control might under certain circumstances be deemed to be a "parachute payment" for tax purposes. In general, if the present value of all parachute payments to a "disqualified individual" (any one of a limited class of stockholders, officers, and highly compensated employees) equals or exceeds three times the individual's "base amount" (annualized compensation over a five-year period), the individual will be

45


subject to a 20% excise tax on the excess of the parachute payments over the individual's base amount, and the employer will be denied a tax deduction for such excess, except to the extent it is established that the excess represents a reasonable compensation for services actually rendered. Payments outside of the Plan also may constitute parachute payments.

New Plan Benefits

        The selection of employees to receive awards under the Plan will be determined by the Committee in its discretion. Therefore, the benefits under the Plan that will be received by any individual or group are not determinable. On April 6, 2004, the closing price of the Common Stock on the New York Stock Exchange was $16.15 per share.

Vote Required

        The affirmative vote of a majority of the shares of the Common Stock, present in person or by proxy and entitled to vote at the Annual Meeting, is required to approve the Plan.

The Board of Directors recommends a vote FOR this proposal.


3. PROPOSAL TO ADOPT THE INTERPUBLIC NON-MANAGEMENT
DIRECTORS' STOCK INCENTIVE PLAN

        The Board of Directors has adopted, and is submitting to stockholders for approval, the Interpublic Non-Management Directors' Stock Incentive Plan.

Background

        In 1994, the stockholders of Interpublic approved the Interpublic Outside Directors' Stock Incentive Plan (formerly called the Interpublic Outside Directors' Stock Option Plan) for the purpose of enabling Interpublic to make equity compensation awards to its non-management directors. A description of the awards currently provided to non-management directors under the plan is set forth in this Proxy Statement under the heading "Election of Directors—Corporate Governance Practices and Board Matters—Non-Management Directors' Compensation".

        The Outside Directors' Stock Incentive Plan will expire by its terms on June 7, 2004. The Board of Directors believes that it is in the best interest of Interpublic and its stockholders to adopt a new plan that will permit Interpublic to continue to provide equity compensation to its non-management directors after expiration of the current plan.

        On March 25, 2004, the Board of Directors adopted the Interpublic Non-Management Directors' Stock Incentive Plan (the "Plan"), subject to approval by Interpublic's stockholders. The Board believes that the new plan will enable Interpublic to continue to attract and retain qualified people to serve as directors, and to enhance shareholder value by aligning the interests of the participating directors with stockholders through the granting of equity awards.

Description of the Non-Management Directors' Stock Incentive Plan

        The text of the Plan is annexed hereto as Appendix C and is hereby incorporated by reference. The following description of the Plan is qualified in its entirety by reference to the text of the Plan.

Administration

        The Plan is administered by the Corporate Governance Committee of the Board of Directors (the "Committee").

46


Eligibility

        Participation in the Plan is limited to directors who are not employees of Interpublic or any of its subsidiaries ("Non-Management Directors"). Each of the seven nominees for election as a director at this Annual Meeting who is not an employee of Interpublic or its subsidiaries will be eligible participants.

Shares Available

        An aggregate of 200,000 shares of Common Stock will be reserved for issuance under the Plan. These shares may be either authorized but unissued shares, treasury shares or shares purchased by Interpublic in the open market. The number of shares reserved for issuance under the Plan is subject to proportionate adjustment by the Corporate Governance Committee to the extent required to prevent dilution or enlargement in the event of any stock split, stock dividend, recapitalization, merger, consolidation, reorganization, combination, exchange of shares or other similar event.

Awards

        The following types of awards are granted in accordance with the specifications of the Plan or are available for grants as the Committee may determine from time to time in its discretion:

        Unrestricted Shares.    Unrestricted shares are shares of Common Stock that are not subject to forfeiture and are free of any and all restrictions on transfer.

        Restricted Shares.    Restricted shares are shares of Common Stock that for an initial period of time are not transferable and are subject to forfeiture. A Non-Management Director who receives a grant of restricted shares has all rights of ownership with respect to the restricted shares, including the right to vote and to receive dividends, except that, prior to the expiration of a three-year restriction period that begins on the date of grant, the Non-Management Director is prohibited from selling, assigning, pledging, hypothecating or otherwise transferring the restricted shares. If a Non-Management Director's service as a director terminates for any reason (including death) on or after the first anniversary of a grant of restricted shares, that portion of the restricted shares corresponding to the number of months of the three-year restriction period that have elapsed since the date of grant will vest and become immediately transferable, and the remainder of the restricted shares will be forfeited. If a Non-Management Director's service terminates for any reason (including death) before the first anniversary of a grant of restricted shares, all of such restricted shares will be forfeited.

        Restricted Share Units.    Restricted share units entitle the holder to receive at the time of the grantee's cessation of service as a Non-Management Director (or at such earlier time as the Committee may approve) a payment in an amount equal to the fair market value of the corresponding number of shares of Common Stock as of the date of cessation of service, payable in cash or in shares of Common Stock, as determined by the Committee. If a Non-Management Director's service as a director terminates for any reason (including death) prior to the first anniversary of a grant of restricted share units, the restricted share units will be immediately forfeited without any payment to the Non-Management Director. If a Non-Management Director's service as a director terminates for any reason (including death) on or after the first anniversary of a grant of restricted share units, the Non-Management Director will retain that portion of the restricted share units corresponding to the number of months of the three-year restriction period that have elapsed since the date of grant, and the remainder of the restricted share units will be forfeited. The Committee, in its discretion may credit the restricted share unit balance of a Non-Management Director with additional restricted share units corresponding to the dividends that are paid from time to time on the Common Stock. Restricted share units are not transferable other than by will or the laws of descent and distribution.

        Stock Options    Stock options entitle the holder to purchase shares of Common Stock at an exercise price equal to the fair market value of the Common Stock on the date of grant. Any options granted become exercisable three years after the date of grant and have a term of ten years, unless sooner

47


terminated. If the holder of an option ceases to be a Non-Management Director before the option is exercisable, the option is forfeited. Any options that are not so forfeited will remain exercisable by the Non-Management Director or his or her legal representatives, heirs or beneficiaries for up to 36 months, but in no event after the expiration of the ten-year option term.

Automatic Annual Grants

        Under the terms of the Plan, the following awards automatically will be made annually to each Non-Management Director:

        Any other awards made under the Plan are at the sole discretion of the Committee.

Termination and Amendment of the Plan

        The Plan may be terminated or amended by the Committee or the Board of Directors as it deems advisable; provided however that no amendment may revoke or alter in a manner unfavorable to a participant any grant of options, unrestricted shares, restricted shares or restricted share units then outstanding, nor may the Committee or the Board of Directors amend the Plan without stockholder approval if such approval is required by any applicable law, regulation or securities exchange listing requirement. No awards under the Plan may be made after May 31, 2009.

Federal Income Tax Consequences

        The material federal income tax consequences of awards under the Plan, based on the current provisions of the Internal Revenue Code and regulations thereunder, are as follows:

        In the case of a grant to a director of restricted shares that are nontransferable and subject to a substantial risk of forfeiture, the director generally will recognize ordinary income equal to the fair market value of the shares received (determined as of the date on which the shares become transferable or not subject to a substantial risk of forfeiture, whichever occurs first), and Interpublic generally will be entitled to a tax deduction in the same amount.

        A director whose shares are both nontransferable and subject to a substantial risk of forfeiture may elect to recognize income when the shares are received, rather than upon the expiration of the transfer restriction or risk of forfeiture. If a director makes this election, the amount of ordinary income, and the amount of Interpublic's tax deduction, are determined as of the date of receipt, rather than upon the expiration of the applicable restrictions.

        In the case of a grant to a director of unrestricted shares, the director generally will recognize ordinary income equal to the fair market value of the shares received (determined as of the date of grant), and Interpublic generally will be entitled to a tax deduction in the same amount.

        When a cash payment is made to a director, the director will recognize the amount of the cash payment as income, and Interpublic generally will be entitled to a tax deduction in the same amount.

        The grant of a stock option to a director will not have tax consequences to the director or to Interpublic. In general, upon the exercise of a stock option, the director will recognize ordinary income equal to the excess of the acquired shares' fair market value on the exercise date over the exercise price, and Interpublic generally will be entitled to a tax deduction in the same amount.

        When a director sells shares that Interpublic granted to the director or shares that the director acquired under a stock option granted by Interpublic, the director will recognize capital gain or loss equal to the difference between the amount realized on the disposition of the shares and the director's basis in the shares. In general, the director's basis in any such shares will be equal to the amount of ordinary income that the director recognized in connection with the receipt or acquisition of the shares plus, in the case of shares acquired under a stock option, the exercise price.

4. APPOINTMENT OF INDEPENDENT AUDITORS

        PricewaterhouseCoopers has been appointed and is acting as independent auditors of Interpublic for 2004. This firm has been Interpublic's independent auditors since 1952. PricewaterhouseCoopers has advised Interpublic that they are independent auditors with respect to Interpublic and its subsidiaries within the meaning of the rules and regulations of the SEC.

        A representative of PricewaterhouseCoopers is expected to be present at the Annual Meeting and will have the opportunity to make a statement and to respond to appropriate questions.

        Interpublic is submitting this proposal to you because the Board of Directors believes that such action follows sound corporate practice. If you do not confirm the appointment of independent auditors, the Board of Directors will consider it a direction to consider selecting other auditors for next year. However, even if you confirm the appointment, the Board of Directors may still appoint new independent auditors at any time during the year if it believes that such a change would be in the best interests of Interpublic and its stockholders.

Fees Paid to PricewaterhouseCoopers

        The following table sets forth the aggregate fees billed by PricewaterhouseCoopers for audit services performed in connection with the consolidated financial statements and reports for fiscal years 2003 and 2002, respectively, and for other services rendered during those years with respect to Interpublic and its subsidiaries.

Other tax services include miscellaneous tax consulting and planning.

50


Audit Committee Pre-Approval of Audit and Permissible Non-Audit Services of Independent Auditors

        The Audit Committee pre-approves all audit and permissible non-audit services provided by the independent auditors. The permissible non-audit services may include audit-related services, tax-related services and all other services. The Audit Committee has adopted a policy for the pre-approval of services provided by the independent auditors. Under the policy, pre-approval is generally provided for up to one year and any pre-approval is detailed as to the particular service or category of services and is subject to a specific budget. In addition, the Audit Committee may also pre-approve particular services on a case-by-case basis. For each proposed non-audit service, the independent auditor is required to provide detailed back-up documentation at the time of approval. The Audit Committee has delegated pre-approval authority to its Chairman for projects less than $100,000, who must report any decision to the Audit Committee at the next scheduled meeting.


THE BOARD OF DIRECTORS RECOMMENDS A VOTE FOR CONFIRMATION
OF THE APPOINTMENT OF PRICEWATERHOUSECOOPERS.


5. STOCKHOLDERS' PROPOSAL REGARDING NORTHERN IRELAND

        Interpublic is advised that three stockholders intend to present the proposal set forth below for consideration and action by stockholders at the Annual Meeting. The names and addresses of these three stockholders and the number of shares of Common Stock each has stated that it owns will be furnished to any shareholder by Interpublic promptly upon receipt by Interpublic of an oral or written request for such information. The stockholders' proposal is as follows:

        WHEREAS, Interpublic Group of Companies, Inc. has a wholly-owned subsidiary in Northern Ireland;

        WHEREAS, the securing of a lasting peace in Northern Ireland encourages us to promote means for establishing justice and equality;

        WHEREAS, employment discrimination in Northern Ireland was cited by the International Commission of Jurists as being one of the major causes of sectarian strife;

        WHEREAS, Dr. Sean MacBride, founder of Amnesty International and Nobel Peace Laureate, has proposed several equal opportunity employment principles to serve as guidelines for corporations in Northern Ireland. These include:

51

RESOLVED: Shareholders request the Board of Directors to:

        Make all possible lawful efforts to implement and/or increase activity on each of the nine MacBride Principles.

Supporting Statement

        We believe that our company benefits by hiring from the widest available talent pool. An employee's ability to do the job should be the primary consideration in hiring and promotion decisions.

        Implementation of the MacBride Principles by Interpublic Group of Companies, Inc. will demonstrate its concern for human rights and equality of opportunity in its international operations.

        Please vote your proxy FOR these concerns.

Interpublic's Statement in Opposition

        Interpublic has two agencies in Northern Ireland: McCann-Erickson Belfast, an agency with approximately 30 employees, which Interpublic acquired in June 1986 (hereinafter referred to as "MEB"); and Weber Shandwick Northern Ireland, an agency with approximately 17 employees, which Interpublic acquired in October 1998 (hereinafter referred to as "WSNI").

        The Board of Directors believes that the policies and practices of MEB and of WSNI are consistent with Interpublic's policy to recruit, employ and promote all qualified personnel without regard to race, creed, color, national origin, sex, age, veteran status or disability.

        Interpublic shares the proponents' concern for human rights and equality of opportunity as well as the need to encourage employment and opportunity in Northern Ireland. It believes that an effective commitment to fair employment has been made in good faith by MEB and by WSNI, and that implementation of all of the MacBride Principles is not necessary or desirable under the circumstances. Furthermore, the Board of Directors believes that it is not practical or prudent for Interpublic to develop solutions in the United States to problems unique to Northern Ireland.

        Interpublic believes that MEB and WSNI are in full compliance with the Fair Employment and Treatment (Northern Ireland) Order 1998, effective in Northern Ireland. Under this law, an employee designated as the Monitoring Officer is required to monitor the religious composition of the workforce and to submit a statutory annual report to the Fair Employment Commission. The Monitoring Officers for MEB and for WSNI report that they have found no evidence of religious or political discrimination in the composition of its workforce.

        MEB has adopted and implements the following Policy Statement on Religious Equality of Opportunity in Employment:

52

        WSNI has advised that it has completed a review of its employment and recruitment practices and procedures as required by Article 55 of the Fair Employment and Treatment (Northern Ireland) Order 1998 and has implemented the following policies with respect to religious equality of opportunity in employment:

53

Vote Required

        The affirmative vote of the majority of the shares present in person or represented by proxy and entitled to vote at the Annual Meeting is required to approve the stockholders' proposal.


THE BOARD OF DIRECTORS RECOMMENDS A VOTE AGAINST THE
STOCKHOLDERS' PROPOSAL REGARDING NORTHERN IRELAND.

INFORMATION FOR STOCKHOLDERS THAT HOLD INTERPUBLIC COMMON STOCK THROUGH A BANK OR BROKER.

        Under SEC rules, brokers and banks that hold stock for the account of their customers are permitted to elect to deliver a single Annual Report and proxy statement (as well as other shareholder communications from the issuer) to two or more shareholders that share the same address. If you and other residents at your mailing address own shares of Common Stock through a broker or bank, you may have received a notice notifying you that your household will be sent only one copy of Interpublic's 2003 Annual Report and this Proxy Statement. If you did not notify your broker or bank of your objection, you may have been deemed to have consented to the arrangement. If you determine that you would prefer in the future to receive a separate copy of Interpublic's Annual Reports and Proxy Statements, you may revoke your consent at any time by notifying Interpublic by letter addressed to The Interpublic Group of Companies, Inc., 1271 Avenue of the Americas, New York, NY 10020, Attention: Secretary or by calling Corporate Communications at (212) 399-8000. Your notification should include the name of your brokerage firm or bank and the number of your account.

        If you would like to receive a separate copy of the 2003 Annual Report or this Proxy Statement, please contact Interpublic at the above address or telephone number. If you hold your shares of Common Stock through a broker or bank and are receiving multiple copies of our Annual Reports and Proxy Statements at your address and would like to receive only one copy for your household, please contact your broker or bank.

INFORMATION FOR PARTICIPANTS IN THE INTERPUBLIC GROUP OF COMPANIES, INC. SAVINGS PLAN.

        Participants in The Interpublic Group of Companies, Inc., Savings Plan (the "Plan") may vote the number of shares of Interpublic's Common Stock equivalent to the interest in Interpublic's Common Stock credited to their accounts under the Plan as of the record date. Participants may vote by instructions given to JPMorgan Chase Bank ("JPMorgan"), the trustee of the Plan, pursuant to the proxy card being mailed with this document to Plan participants. JPMorgan has informed us that it will vote shares in accordance with duly executed instructions if received on or before May 13, 2004. JPMorgan further informs us that if JPMorgan does not receive timely instructions, the Common Stock credited to that participant's account, pursuant to the terms of the Trust Agreement executed by Interpublic and JPMorgan, will not be voted by JPMorgan. JPMorgan will vote any shares of Common Stock held by the Plan that are not specifically

54


allocated to any individual Plan participant (known as the suspense account) in the same proportion that JPMorgan votes the Common Stock for which it receives timely instructions.


SOLICITATION OF PROXIES

        This solicitation of proxies is made on behalf of the Board of Directors of Interpublic. Solicitation of proxies will be primarily by mail. In addition, proxies may be solicited in person or by telephone, telefax, e-mail or other means by officers, directors and employees of Interpublic, for which they will receive no additional compensation.
