                              SELLING STOCKHOLDERS

         The following table sets forth certain information with respect to the
selling stockholders, including:

         o  the name of each selling stockholder

         o  the number of shares of common stock beneficially owned by such
            selling stockholder prior to the offering

         o  the maximum number of shares of such common stock to be offered by
            such selling stockholder hereby

         o  the number of shares of common stock to be beneficially owned by
            such selling stockholder assuming all of the shares of such selling
            stockholder covered by this prospectus are distributed in the
            offering

         No selling stockholder beneficially owns one percent (1%) or more of
Interpublic's issued and outstanding common stock.

         Each selling stockholder is a former equity or debt holder of a company
acquired by Interpublic or the assignee of such a person.

         Because the selling stockholders may offer all, a portion or none of
the common stock offered pursuant to this prospectus, no estimate can be given

stockholders upon termination of the offering. See "Plan of Distribution."

                              PLAN OF DISTRIBUTION

         Interpublic has not been advised by the selling stockholders as to any
plan of distribution. Distribution of the common stock by the selling
stockholders, or by pledgees, hedging or derivative transaction counterparties,
donees (including charitable organizations), transferees or other successors in
interest, may be effected from time to time in one or more transactions (which
may involve block transactions):

         o  on the New York Stock Exchange in transactions that may include
            special offerings and exchange distributions pursuant to and in
            accordance with the rules of such exchange,

         o  in the over-the-counter market,

         o  in transactions otherwise than on such exchange or in the
            over-the-counter market, including "block trades" and direct
            transactions between the sellers and the purchasers without a broker
            dealer, or

         o  in a combination of any such transactions.

         Such transactions may be effected by the selling stockholders at market
prices prevailing at the time of sale, at prices related to such prevailing
market prices, at negotiated prices or at fixed prices. The selling stockholders
may effect such transactions by selling the common stock to or through market
makers or broker-dealers, and such market makers or broker-dealers may receive
compensation in the form of discounts or commissions from the selling
stockholders and may receive commissions from the purchasers of the common stock
for whom they may act as agent. The selling stockholders may agree to indemnify
any broker-dealer or agent that participates in transactions involving sales of
the shares against certain liabilities, including liabilities arising under the
Securities Act.

         We have agreed to bear certain expenses (excluding any underwriting
fees, expenses, discounts or other costs payable to any underwriter, broker or
dealer and fees and expenses of counsel to the selling securityholders) in
connection with the registration and sale of the common stock being offered by
the selling stockholders, estimated to be approximately $106,967. We have agreed
to indemnify the selling stockholders against certain liabilities, including
certain liabilities under the Securities Act.

         The selling stockholders and any broker-dealers or agents that
participate with the selling stockholders in the distribution of the common
stock may be deemed to be "underwriters" within the meaning of the Securities
Act, and any commissions received by them and any profit on the resale of any
common stock purchased by them may be deemed to be underwriting commissions or
discounts under the Securities Act.

                                  LEGAL MATTERS

         The validity of the common stock being offered hereby will be passed
upon for Interpublic by Nicholas J. Camera, Esq., Senior Vice President, General
Counsel and Secretary of Interpublic.

ITEM 15.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.


         Section 145 of Title 8 of the General Corporation Law of the State of
Delaware ("GCL") gives a corporation power to indemnify any person who was or is
a party or is threatened to be made a party to any threatened, pending or
completed action, suit or proceeding, whether civil, criminal, administrative or
investigative (other than an action by or in the right of the corporation) by
reason of the fact that such person is or was a director, officer, employee or
agent of the corporation, or is or was serving at the request of the corporation
as a director, officer, employee or agent of another corporation, partnership,
joint venture, trust or other enterprise, against expenses (including attorneys'
fees), judgments, fines and amounts paid in settlement actually and reasonably
incurred by him in connection with such action, suit or proceeding, provided
that such director, officer, employee or agent acted in good faith and in a
manner reasonably believed to be in or not opposed to the best interests of the
corporation, and, with respect to any criminal action or proceeding, provided
that such director, officer, employee or agent had no reasonable cause to
believe his or her conduct was unlawful. The same Section also gives a
corporation power to indemnify any person who was or is a party or is threatened
to be made a party to any threatened, pending or completed action or suit by or
in the right of the corporation to procure a judgment in its favor by reason of
the fact that such person is or was a director, officer, employee or agent of
the corporation, or is or was serving at the request of the corporation as a
director, officer, employee or agent of another corporation, partnership, joint
venture, trust or other enterprise against expenses (including attorneys' fees)
actually and reasonably incurred by such person in connection with the defense
or settlement of such action or suit if he acted in good faith and in a manner
reasonably believed to be in or not opposed to the best interests of the
corporation, except that no indemnification shall be made in respect of any
claim, issue or matter as to which such person shall have been adjudged to be
liable to the corporation, unless and only to the extent that the Court of
Chancery or the court in which such action or suit was brought shall determine
upon application that, despite the adjudication of liability but in view of all
the circumstances of the case, such person is fairly and reasonably entitled to
indemnity for such expenses which the Court of Chancery or such other court
shall deem proper. Section 145 of the GCL further provides that, to the extent
that a director, officer, employee or agent of a corporation has been successful
on the merits or otherwise in defense of any such action, suit or proceeding, or
in defense of any claim, issue or matter therein, he or she shall be indemnified
against expenses (including attorneys' fees) actually and reasonably incurred by
him or her in connection therewith.

         The Company's by-laws contain specific authority for indemnification by
the Company of current and former directors, officers, employees or agents of
the Company on terms that have been derived from Section 145 of Title 8 of the
GCL.

         The Company maintains policies of insurance under which the Company and
its directors and officers are insured, subject to specified exclusions and
deductible and maximum amounts, against loss arising from any claim which may be
made against the Company or any director or officer of the Company by reason of
any breach of duty, neglect, error, misstatement, omission or act done or
alleged to have been done while acting in their respective capacities.

                       Registration Statement).

ITEM 17.  UNDERTAKINGS.

         (a)  The undersigned registrant hereby undertakes:

         (1) To file, during any period in which offers or sales are being made
of the securities registered hereby, a post-effective amendment to this
registration statement;

         (i)    To include any prospectus required by Section 10(a)(3) of the
                Securities Act of 1933;

         (ii)   To reflect in the prospectus any facts or events arising after
                the effective date of the registration statement (or the most
                recent post-effective amendment thereof) which, individually or
                in the aggregate, represent a fundamental change in the
                information set forth in this registration statement.
                Notwithstanding the foregoing, any increase or decrease in
                volume of securities offered (if the total dollar value of
                securities offered would not exceed that which was registered)
                and any deviation from the low or high end of the estimated
                maximum offering range may be reflected in the form of
                prospectus filed with the SEC pursuant to Rule 424(b) if, in the
                aggregate, the changes in volume and price represent no more
                than a 20 percent change in the maximum aggregate offering price
                set forth in the "Calculation of Registration Fee" table in this
                registration statement; and

         (iii)  To include any material information with respect to the plan of
                distribution not previously disclosed in this registration
                statement or any material change to such information in this
                registration statement;

provided, however, that the undertakings set forth in paragraphs (i) and (ii)
above do not apply if the information required to be included in a
post-effective amendment by those paragraphs is contained in periodic reports
filed with or furnished to the Commission by the registrant pursuant to Section
13 or Section 15(d) of the Securities Exchange Act of 1934 that are incorporated
by reference in this registration statement.

         (2) That, for the purpose of determining any liability under the
Securities Act of 1933, each such post-effective amendment shall be deemed to be
a new registration statement relating to the securities offered herein, and the
offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof.

         (3) To remove from registration by means of a post-effective amendment
any of the securities being registered which remain unsold at the termination of
the offering.

         (b) The undersigned registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act of 1933, each filing of the
registrant's annual report pursuant to Section 13(a) or Section 15(d) of the
Securities Exchange Act of 1934 that is incorporated by reference in the
registration statement shall be deemed to be a new registration statement
relating to the securities offered therein, and the offering of such securities
at that time shall be deemed to be the initial bona fide offering thereof.

         (c) Insofar as indemnification for liabilities arising under the
Securities Act of 1933 may be permitted to directors, officers and controlling
persons of the registrant pursuant to the foregoing provisions or otherwise, the
registrant has been advised that in the opinion of the Securities and Exchange
Commission such indemnification is against public policy as expressed in the
Securities Act of 1933 and is, therefore, unenforceable. In the event that a
claim for indemnification against such liabilities (other than the payment by
the registrant of expenses incurred or paid by a director, officer or
controlling person of the registrant in the successful defense of any action,
suit or proceeding) is asserted by such director, officer or controlling person
in connection with the securities being registered, the registrant will, unless
in the opinion of its counsel the matter has been settled by controlling
precedent, submit to a court of appropriate jurisdiction the question whether
such indemnification by it is against public policy as expressed in the
Securities Act of 1933 and will be governed by the final adjudication of such
issue.

         (d)  The undersigned registrant hereby undertakes that:

         (1) For purposes of determining any liability under the Securities Act
of 1933, the information omitted from the form of prospectus filed as part of
this registration statement in reliance upon Rule 430A and contained in a form
of prospectus filed by the registrant pursuant to Rule 424(b)(1) or (4) or
497(h) under the Securities Act of 1933 shall be deemed to be part of this
registration statement as of the time it was effective.

         (2) For the purpose of determining any liability under the Securities
Act of 1933, each post-effective amendment that contains a form of prospectus
shall be deemed to be a new registration statement relating to the securities
offered therein, and the offering of such securities at that time shall be
deemed to be initial bona fide offering thereof.


                                   SIGNATURES

         Pursuant to the requirements of the Securities Act of 1933, the
registrant certifies that it has reasonable grounds to believe that it meets all
of the requirements for filing on Form S-3 and has duly caused this registration
statement to be signed on its behalf by the undersigned, thereunto duly
authorized, in The City of New York, State of New York, on the 18th day of July
2000.
