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. EXPERTS The consolidated financial statements of Interpublic and its subsidiaries incorporated in this prospectus by reference to Interpublic's Annual Report on Form 10-K for the year ended December 31, 1999 and the supplemental consolidated financial statements of Interpublic and its subsidiaries incorporated in this prospectus by reference to Interpublic's Current Report on Form 8-K dated July 17, 2000 have been so incorporated in reliance on the report of PricewaterhouseCoopers LLP, independent accountants, and, insofar as it relates to the financial statements (not separately presented in Interpublic's Annual Report on Form 10-K for the year ended December 31, 1999 and the Current Report on Form 8-K dated July 17, 2000) of Hill, Holliday, Connors, Cosmopulos, Inc., International Public Relations plc and the MBL Group PLC, for the year ended December 31, 1997, and NFO Worldwide Inc. for the years ended December 31, 1999 and 1998 and the three year period ended December 31, 1999, each a wholly-owned subsidiary of Interpublic, the reports of Ernst & Young LLP, Ernst & Young, Soteriou Banerji and Arthur Andersen LLP, respectively, given on the authority of said firms as experts in auditing and accounting.

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.

(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.

He shall disburse the funds of the Corporation as may be ordered by the Board of Directors, taking proper vouchers for such disbursements, and shall render to the Chairman of the Board and the Board of Directors, at regular meetings of the Board of Directors, or whenever they may require it, an account of all his transactions as Treasurer and of the financial condition of the Corporation. He shall give the Corporation a bond if required by the Board of Directors, in such sum and with such surety or sureties as shall be satisfactory to the Board of Directors, for the faithful performance of the duties of his office, and for the restoration to the Corporation, in case of his death, resignation, retirement or removal from office, of all books, papers, vouchers, money and other property of whatever kind in his possession or under his control belonging to the Corporation.

The compensation of all other officers, employees and agents of the Corporation shall be fixed by the Board of Directors, the Chairman of the Board, or by such other persons as shall be designated by the Board of Directors or the Chairman of the Board. Article 6 Indemnification Section 6.01. Actions other than those by or in the right of the Corporation. The Corporation shall 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 he 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 if he acted in good faith and in a manner he reasonably believed to be in or not opposed to the best interests of the Corporation, and, with respect to any criminal action or proceeding, had no reasonable cause to believe his conduct was unlawful. The termination of any action, suit or proceeding by judgment, order, settlement, conviction, or upon a plea of nolo contendere or its equivalent, shall not, of itself, create a presumption that the person did not act in good faith and in a manner which he reasonably believed to be in or not opposed to the best interests of the Corporation, and, with respect to any criminal action or proceeding, had reasonable cause to believe that his conduct was unlawful. Section 6.02. Actions by or in the right of the Corporation. The Corporation shall 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 he 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 him in connection with the defense or settlement of such action or suit if he acted in good faith in a manner he reasonably believed to be in or not opposed to the best interests of the Corporation. The foregoing sentence to the contrary notwithstanding, 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 for negligence or misconduct in the performance of his duty 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 6.03. Indemnification against Expenses. To the extent that a director, officer, employee or agent of the Corporation has been successful on the merits or otherwise in defense of any action, suit or proceeding referred to in Section 6.01 or 6.02 hereof, or in defense of any claim, issue or matter therein, he shall be indemnified against expenses (including attorneys' fees) actually and reasonably incurred by him in connection therewith. Section 6.04. Authorization. Any indemnification under Section 6.01 or Section 6.02 hereof (unless ordered by a court) shall be made by the Corporation only as authorized in the specific case upon a determination that indemnification of the director, officer, employee or agent is proper in the circumstances because he has met the applicable standard of conduct set forth in Sections 6.01 and 6.02, and that he has reasonably cooperated with the Corporation in the conduct of such action, suit or proceeding. Such determination shall be made (a) by the Board of Directors by a majority vote of a quorum consisting of directors who were not parties to such action, suit or proceeding, or (b) if such quorum is not obtainable (or, even if it is obtainable, a quorum of disinterested directors so directs), by independent legal counsel in a written opinion, or (c) by the stockholders. Section 6.05. Payment of Expenses in Advance of Final Disposition. Expenses incurred in defending a civil or criminal action, suit or proceeding may be paid by the Corporation in advance of the final disposition of such action, suit or proceeding as authorized by the Board of Directors in the manner provided in Section 6.04 hereof upon receipt of an undertaking by or on behalf of the director, officer, employee or agent to repay such amount unless it shall ultimately be determined that he is entitled to be indemnified by the Corporation as authorized in this Article 6. Section 6.06. Non-Exclusivity. The indemnification provided by this Article 6 shall not be deemed exclusive of any other rights to which those indemnified may be entitled under any by-law, agreement, vote of stockholders or disinterested directors or otherwise, both as to action in his official capacity and as to action in another capacity while holding such office, and shall continue as to a person who has ceased to be a director, officer, employee or agent and shall inure to the benefit of the heirs, executors and administrators of such a person. Section 6.07. Application. The provisions of this Article 6 shall not be construed to authorize indemnification in any case or for any liability or expense where such indemnification would not be lawful. The shall be applicable to claims, actions, suits and proceedings made or commenced after the adoption hereof, whether arising from acts or omissions to act occurring before or after the date of such adoption. If a person meets the requirements of this Article 6 with respect to some matters in a claim, action, suit or proceeding but not with respect to others, he shall be entitled to indemnification as to the former. Article 7 Stock Certificates Section 7.01. Issuance of Certificates. Every holder of stock in the Corporation shall be entitled to have a certificate signed by, or in the a name of the Corporation by, the Chairman of the Board or the President or a Vice President, and by the Treasurer or an Assistant Treasurer, or the Secretary or an Assistant Secretary, certifying the number of shares owned by him in the Corporation. If such certificate is countersigned (1) by a transfer agent other than the Corporation or its employee, or (2) by a registrar other than the Corporation or its employee, any other signature on the certificate may be a facsimile. In case any officer, transfer agent or registrar who has signed or whose facsimile signature has been placed upon a certificate shall have ceased to be such officer, transfer agent or registrar before such certificate issued, it may be issued by the Corporation with the same effect as if he were such officer, transfer agent or registrar at the date of issue. Section 7.02. Form of Certificates. The certificates representing each class of the capital stock of the Corporation shall be in such form as shall be approved by the Board of Directors. They shall bear on their face appropriate legends conspicuously calling attention to the designations, preferences and rights, and the qualifications, limitations or restrictions thereof, of the class of stock in question, and to the restrictions on transfer and registration set forth in the Certificate of Incorporation. If a full statement of such designations, preferences, rights, qualifications, limitations and restrictions is not printed on the face or back of each certificate, the Corporation shall (and each certificate shall state that the Corporation will) furnish a copy of such full statement to any stockholder upon request and without charge. The acceptance of any stock certificate shall constitute assent to all applicable provisions of the Certificate of Incorporation and of these By-Laws whether or not the stockholder thus accepting the certificate shall have requested a copy of the full statement referred to in the preceding sentence. Section 7.03. Lost, Stolen or Destroyed Certificates. The Board of Directors, or any officer or officers thereunto duly authorized by the Board of Directors, may authorize the issuance of a new certificate of stock in the place of any certificate theretofore issued by the Corporation, alleged to have been lost, stolen or destroyed, upon the making of an affidavit of such loss, theft or destruction by the owner thereof or his legal representative. The Board of Directors or the officer or officers thereunto duly authorized by the board may, in its, his or their discretion as a condition precedent to the issuance of such new certificate, require such owner or legal representative to give the Corporation a bond sufficient to indemnify it against any claim that may be made against it on account of the alleged loss, theft or destruction of any such certificate or the issuance of such new certificate. Article 8 Transfers of Stock Section 8.01. Registration of Transfers. Except as otherwise provided (and subject to the limitations of ownership set forth) in the Certificate of Incorporation, shares of the capital stock of the Corporation shall be transferable ton the books of the Corporation by the holder thereof in person or by his duly authorized attorney, upon surrender to the Corporation or its transfer agent of the duly endorsed certificate or certificates for such shares together with (a) stamps evidencing payment of any applicable stock transfer tax or a cash payment sufficient to reimburse the Corporation for payment of such tax, and (b) such guaranty or proof of the authenticity of the endorsement as the Corporation or its transfer agent may reasonably require. Section 8.02. Transfer Agents and Registrars. The Board of Directors may, in its discretion, appoint banks or trust companies in such city or cities as the Board may deem advisable, from time to time, to act as transfer agents and registrars of any class or classes of the capital stock of the Corporation. Upon such appointments being made, no stock certificate shall be valid until countersigned by one of such transfer agents and registered by one or such registrars. Article 9 Delegation of Authority Section 9.01. Officers' Duties. In the event of the absence or disability of any officer of the Corporation for which a substitution is not prescribed in these By-Laws, or for any other reason it may deem sufficient, the Board of Directors may by the affirmative vote of a majority of the whole Board delegate all or any of the powers and duties of such officer for the time being to any other officer or to any director. Section 9.02. Negotiable Instruments. All bills, notes, checks or other instruments for the payment of money shall be signed or countersigned by such officers or agents and in such manner as, from time to time, may be prescribed by resolution (whether general or special) of the Board of Directors, or as may be prescribed by any officer or officers thereunto duly authorized by the Board of Directors. Section 9.03. Voting Upon Stocks. Unless otherwise ordered by the Board of Directors, the Chairman of the Board shall have full power and authority on behalf of the Corporation to attend and to act and to vote at any meetings of stockholders of any corporation in which the Corporation may hold stock, and at any such meeting shall possess and may exercise any and all rights and powers incident to the ownership of such stock, and which, as the owner thereof, the Corporation might have possessed and exercised if present. The Board of Directors, by resolution, from time to time, may confer like powers upon any other person or persons. Section 9.04. Attorneys. The Board of Directors may, from time to time, appoint one or more attorneys-in-fact to act for and in representation of the Corporation, either generally or specially, judicially or extra-judicially, and may delegate to any such attorney or attorneys-in-fact all or any powers which, in the judgment of the board, may be necessary, advisable, convenient or suitable for exercise in any country or jurisdiction in the administration or management of the business of the Corporation, or the defense or enforcement of its rights, even though such powers be herein provided or directed to be exercised by a designated officer of the Corporation, or by the Board of Directors. The act of the Board of Directors in conferring any such powers upon, or delegating the same to, any attorney-in-fact shall be conclusive evidence in favor of any third person of the right of the Board of Directors so to confer or delegate such powers; and the exercise by any attorney-in-fact of any powers so conferred or delegated shall in all respects be binding upon the Corporation. Article 10 Miscellaneous Section 10.01. Seal. The Board of Directors shall provide a suitable seal, containing the name of the Corporation, the year of its organization and the words "Corporate Seal, Delaware," which seal shall be in the custody of the Secretary. If and when so directed by the Board of Directors a duplicate of the seal may be kept and used by the Treasurer or by an Assistant Secretary or Assistant Treasurer. Section 10.02. Fiscal Year. The fiscal year of the Corporation shall be the calendar year. Section 10.03. Inspection of Books. The Board of Directors shall determine from time to time whether, when and under what conditions and regulations the accounts and books of the Corporation (except such as may by statute be specifically open to inspection) or any of them shall be open to the inspection of the stockholders, and the stockholders' rights in this respect are and shall be restricted and limited accordingly. Section 10.04. Registered Stockholders. The Corporation shall be entitled to treat the holder of record of any share or shares of stock as the holder in fact thereof, and accordingly shall not be bound to recognize any equitable or other claim to or interest in such share on the part of any other person, whether or not it shall have express or other notice thereof, save as expressly provided by the law of Delaware. Section 10.05. Waiver of Notice. Whenever notice is required to be given under any provision of the General Corporation Law of Delaware, the Certificate of Incorporation or these By-Laws, a written waiver thereof signed by the person or persons entitled to notice, whether before or after the time stated therein, shall be deemed equivalent to notice. Attendance of a person at a meeting of stockholders shall constitute a waiver of notice of such meeting, except as otherwise provided by law. Neither the business to be transacted at nor the purpose of any regular or special meeting of the stockholders or the Board of Directors, except business specified in the first sentence of Section 3.07 or in Section 10.06 of these By-Laws, need be specified in any written waiver or notice. Section 10.06. Amendment. Any provision of these By-Laws may be altered or repealed at any regular or special meeting of the stockholders or the Board of Directors if notice of the proposed alteration or repeal is set forth in the notice of such meeting, whether or not notice of such meeting is otherwise required.

New York, New York 10020

         Re:   The Interpublic Group of Companies, Inc.,
               Registration Statement on Form S-3

Ladies and Gentlemen:

                  I am General Counsel of The Interpublic Group of Companies,
Inc., a Delaware corporation (the "Corporation"), and have acted as such in
connection with the preparation and filing with the Securities and Exchange
Commission (the "Commission") under the Securities Act of 1933, as amended (the
"Act"), of the above-captioned Registration Statement on Form S-3 (the
"Registration Statement"), relating to the registration of 3,217,582 shares of
the Corporation's Common Stock, $.10 par value (the "Shares").

                  In arriving at the opinions expressed below, I have examined
and relied on the originals or copies certified or otherwise identified to my
satisfaction of all such corporate records of the Corporation and such other
instruments and other certificates of public officials, officers and
representatives of the Corporation and such other persons, and I have made such
investigation of law, as I have deemed appropriate as a basis for the opinions
expressed below. In rendering the opinions expressed below, I have assumed and
have not verified that the signatures on all documents that I have examined are
genuine.

                  Based on the foregoing, it is my opinion that:

                  1. The Corporation is validly existing as a corporation in
good standing under the laws of the State of Delaware.

                  2. The Shares have been duly authorized by all necessary
corporate action of the Corporation, and are legally issued, fully paid and
non-assessable.

                  Insofar as the foregoing opinions relate to the validity,
binding effect or enforceability of any agreement or obligation of the Company,
(a) I have assumed that each other party to such agreement or obligation has
satisfied those legal requirements that are applicable and it to the extent
necessary to make such agreement or obligation enforceable against it, and (b)
such opinions are subject to applicable bankruptcy, insolvency and similar laws
affecting creditors' rights generally and to general principles of equity.

                  I hereby consent to the filing of this opinion as an exhibit
to the Registration Statement and to the reference to my name in the
Registration Statement and the related Prospectus under the caption "Legal
Matters." By giving such consent, I do not admit that I am an "expert" within
the meaning of the Act or the rules and regulations of the Commission issued
thereunder with respect to any part of the Registration Statement, including
this exhibit.

                                               Very truly yours,

                                               /s/ Nicholas J. Camera
