Item 5. Interests of Named Experts and Counsel. Angeline C. Straka, Esq., Senior Vice President, Deputy General Counsel and Secretary of the Registrant, who has rendered an opinion stating that under applicable state law the shares of Class B Common Stock to which the Registration Statement relates will be, when issued and delivered, validly and legally issued, fully paid and non-assessable under the laws of the State of Delaware. As of January 19, 2006, Ms. Straka held 790 shares of Class B Common Stock, par value $0.001 per share, of the Registrant and held exercisable options to acquire approximately 380,989 shares of Class B Common Stock of the Registrant and non-exercisable options to acquire approximately 23,767 shares of Class B Common Stock of the Registrant. Item 6. Indemnification of Directors and Officers. Section 102(b)(7) of the Delaware General Corporation Law ("DGCL") allows a corporation to include in its certificate of incorporation a provision eliminating or limiting the personal liability of a director to the corporation or its stockholders for monetary damages for breach of fiduciary duty as a director, except in cases where the director breached his duty of loyalty to the corporation or its stockholders, failed to act in good faith, engaged in intentional misconduct or a knowing violation of the law, willfully or negligently authorized the unlawful payment of a dividend or approved an unlawful stock redemption or repurchase or obtained an improper personal benefit. The Registrant's Amended and Restated Certificate of Incorporation (the "CBS Charter") contains provisions that eliminate directors' personal liability, in certain circumstances. Pursuant to the CBS Charter and the Registrant's Amended and Restated Bylaws (the "CBS Bylaws"), the Registrant shall indemnify any person who was or is involved in or is threatened to be involved in any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative, by reason of the fact that he is or was a director, officer or employee of the Registrant, or is or was serving at the request of the Registrant as a director, officer or employee (including a trustee) of another corporation, partnership, joint venture, trust or other enterprise (such person, an "indemnitee"), to the fullest extent authorized by the DGCL, as the same exists or may hereafter be amended, against judgments, fines, amounts paid in settlement and expenses (including attorneys' fees), actually and reasonably incurred by him in connection with such action, suit or proceeding. Notwithstanding the foregoing, except with respect to proceedings to enforce rights to indemnification and advancement of expenses, the Registrant shall indemnify an indemnitee in connection with a proceeding (or part thereof) initiated by the indemnitee, if and only if the Board of Directors of the Registrant authorized the bringing of the action, suit or proceeding (or part thereof) in advance of the commencement of the proceeding. Pursuant to the CBS Charter and the CBS Bylaws, to the extent that an indemnitee has been successful on the merits or otherwise in defense of any action, suit or proceeding referred to above, or in defense of any claim, issue or matter therein, such person shall be indemnified against expenses (including attorneys' fees) actually and reasonably incurred by him in connection therewith. The indemnification and advancement of expenses provided by, or granted pursuant to, the indemnification provisions of the CBS Charter and the CBS Bylaws shall not be deemed exclusive of any other rights to which a person seeking indemnification or advancement of expenses may be entitled under any statute, bylaw, 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. Without limiting the foregoing, the Registrant is authorized to enter into an agreement with any director, officer or employee of the Registrant providing indemnification for such person against expenses, including attorneys' fees, judgments, fines and amounts paid in settlement that result from any threatened, pending or completed action, suit, or proceeding, whether civil, criminal, administrative or investigative, including any action, suit or proceeding by or in the right of the Registrant, that arises by reason of the fact that such person is or was a director, officer or employee of the Registrant, or is or was serving at the request of the II-2

Registrant as a director, officer or employee of another corporation, partnership, joint venture, trust or other enterprise, to the fullest extent allowed by law, except that no such agreement shall provide for indemnification for any actions that constitute fraud, actual dishonesty or willful misconduct. The Registrant may purchase and maintain insurance on behalf of any person who is or was a director, officer or employee of the Registrant, or is or was serving at the request of the Registrant as a director, officer or employee of another corporation, partnership, joint venture, trust or other enterprise against any liability asserted against him and incurred by him in any such capacity, or arising out of his status as such, whether or not the Registrant would have the power to indemnify him against such liability under the provisions of the CBS Charter. The Registrant has purchased certain liability insurance for its officers and directors as permitted by Section 145(g) of the DGCL. Item 7. Exemption from Registration Claimed. Not Applicable. Item 8. Exhibits. See Exhibit Index. Item 9. Undertakings. (a) The undersigned Registrant hereby undertakes: (1) To file, during any period in which offers or sales are being made, a post-effective amendment to this Registration Statement: (i) to include any prospectus required by Section 10(a)(3) of the Securities Act; (ii) 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; (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 the Registration Statement; provided, however, that the undertakings set forth in paragraphs (1)(i) and (1)(ii) 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 Exchange Act that are incorporated by reference in this Registration Statement. (2) That, for the purpose of determining any liability under the Securities Act, each such post-effective amendment 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. II-3

(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 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. (c) 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. II-4
