     We are not aware of any restrictions on our present or future ability to
pay dividends. However, in connection with certain borrowing facilities entered
into by Interpublic and its subsidiaries, we are subject to certain restrictions
on the ratio of cash flow to consolidated borrowings, the ratio of consolidated
borrowings to net worth and the minimum amount of net worth. Any future dividend
payments will be made at the discretion of Interpublic's board of directors.





                              SELLING STOCKHOLDERS

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

          -       the name of each selling stockholder;

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

          -       the maximum number of shares of such common stock to be
                  offered by such selling stockholder hereby; and

          -       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.

     Because the selling stockholders or their transferees may offer all, a
portion or none of the common stock offered pursuant to this prospectus, no
estimate can be given as to the amount of common stock that will be held by the
selling stockholders upon termination of the offering. See "Plan of
Distribution."

(1) Each selling stockholder is a former shareholder or option holder of a
    company acquired by Interpublic, or the assignee of such former
    shareholder or option holder. A number of the selling stockholders are or
    have been employees or officers of affiliates of Interpublic.

(2) These shares will be issued upon the exercise of a like number of options.






                              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, 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):

          -    on the NYSE in transactions that may include special offerings
               and exchange distributions pursuant to and in accordance with the
               rules of such exchange,

          -    in the over-the-counter market, or

          -    in transactions otherwise than on such exchange or in the
               over-the-counter market, or 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
broker-dealers, and such 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)
in connection with the registration and sale of the common stock being offered
by the selling stockholders, estimated to be approximately $44,000. 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 capabilities.

            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.
