INDEMNIFICATION OF DIRECTORS AND OFFICERS. Section 145 of Title 8 of the General Corporation Law of the State of Delaware permits a corporation 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 the 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 the director, officer, employee or agent acted in good faith and in a manner reasonably believed to be in or not opposed by the best interests of the corporation, and, with respect to any criminal action or proceeding, provided that the director, officer, employee or agent had no reasonable cause to believe his or her conduct was unlawful. Section 145 also permits a corporation 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 the 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 the 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 the 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, the person is fairly and reasonably entitled to indemnity for the expenses which the Court of Chancery or such other court shall deem proper. Section 145 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 Registrant's By-laws contain specific authority for indemnification by the Registrant of current and former directors, officers, employees or agents of the Registrant on terms that have been derived from Section 145 of Title 8 of the General Corporation Law of the State of Delaware.

Camera. 23.1 Consent of Nicholas J. Camera (included in Exhibit 5.1). 23.2 Consent of PricewaterhouseCoopers LLP. 23.3 Consent of Arthur Andersen LLP (with respect to True North Communications, Inc.) 23.4 Consent of Arthur Andersen LLP (with respect to NFO Worldwide, Inc.). 23.5 Consent of J.H. Cohn LLP. 24.1 Power of Attorney of Directors of the Registrant (included on signature pages of this Part II). ITEM 9. UNDERTAKINGS. (1) The undersigned Registrant hereby undertakes to file, during any period in which offers or sales are being made, a post-effective amendment to this Registration Statement: (a) to include any prospectus required by Section 10(a)(3) of the Securities Act of 1933 (the "Securities Act"); (b) to reflect in the prospectus any facts or events arising after the effective date of this 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; and (c) 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 paragraphs 1(a) and 1(b) do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in periodic reports filed by the Registrant pursuant to Section 13 or Section 15(d) of the Exchange Act that are incorporated by reference in this Registration Statement. (2) The undersigned Registrant hereby undertakes that, for the purpose of determining any liability under the Securities Act, each post-effective amendment described under paragraph (1), above, 4

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. (3) The undersigned Registrant hereby undertakes 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. (4) The undersigned Registrant hereby undertakes that, for purposes of determining liability under the Securities Act, each filing of the Registrant's annual report pursuant to Section 13(a) or Section 15(d) of the Exchange Act that is incorporated by reference in this 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. (5) Insofar as indemnification for liabilities arising under the Securities Act 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 Commission such indemnification is against public policy as expressed in the Securities Act 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 and will be governed by the final adjudication of such issue. 5

SIGNATURES Pursuant to the requirements of the Securities Act, the Registrant certifies that it has reasonable grounds to believe that it meets all of the requirements for filing on Form S-8 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 May 31, 2002.
