Item 1.01 Entry into a Material Definitive Agreement

On December 17, 2012, Arbitron Inc., a Delaware corporation (the “Company”), entered into an Agreement and Plan of Merger (the “Merger Agreement”) with Nielsen Holdings N.V., a Dutch public company with limited liability (naamloze vennootschap) (“Parent”), and TNC Sub I Corporation, a Delaware corporation and an indirect wholly owned subsidiary of Parent (“Merger Sub”).

Merger Agreement

Pursuant to the terms of the Merger Agreement, subject to the satisfaction or waiver of certain conditions set forth in the Merger Agreement, Merger Sub will be merged with and into the Company (the “Merger”), and the Company will become an indirect wholly-owned subsidiary of Parent at the effective time of the Merger (the “Effective Time”). At the Effective Time, each share of the common stock of the Company, par value $0.50 per share (the “Common Stock”), issued and outstanding immediately prior to the Effective Time (other than shares held by the Company, Parent, Merger Sub or any Company stockholders who perfect their statutory rights of appraisal under Delaware law) will be converted into the right to receive $48.00 in cash (the “Merger Consideration”).

The boards of directors of each of the Company and Parent have approved the Merger Agreement and the Merger.

The Merger Agreement includes customary representations, warranties and covenants by the parties. The Company has agreed, among other things, to operate its business in the ordinary course until the Merger is consummated. The Company has agreed not to solicit or initiate discussions with third parties regarding other proposals to acquire the Company and has agreed to certain restrictions on its ability to respond to such proposals, subject to the fulfillment of the fiduciary duties of the Company’s board of directors. In addition, certain covenants require each of the parties to use reasonable best efforts to cause the Merger to be consummated.

Consummation of the Merger is subject to various customary closing conditions, including, (i) the receipt of the Company Stockholder Approval (as defined in the Merger Agreement), (ii) the absence of any law, injunction, judgment or ruling enjoining or prohibiting the Merger, (iii) the accuracy of the representations and warranties made by the parties, (iv) the performance by the parties in all material respects of their covenants, obligations and agreements under the Merger Agreement and (v) the expiration or early termination of the waiting period applicable to the Merger under the Hart-Scott Rodino Antitrust Improvements Act of 1976, as amended. Consummation of the Merger is not subject to any financing contingencies.

The Merger Agreement contains certain termination rights and provides that upon termination of the Merger Agreement by the Company or Parent upon specified conditions, including a termination prior to the requisite stockholder approval of the Merger by the Company to accept a “Superior Company Proposal” (as defined in the Merger Agreement) or by Parent upon a change in the recommendation of the Company’s board of directors, the Company will be required to pay Parent a termination fee of $32.7 million, and upon termination of the Merger Agreement by the Company or Parent upon specified conditions (including a failure to satisfy certain conditions relating to antitrust laws or Parent’s breach of certain of its covenants related to its efforts to obtain antitrust approvals), Parent will be required to pay the Company a termination fee of $131.0 million. In addition, subject to certain exceptions and limitations, either party may terminate the Merger Agreement if the Merger is not consummated by October 1, 2013 (as such date may be extended under certain circumstances).

The foregoing description of the Merger Agreement does not purport to be complete and is qualified in its entirety by reference to the full text of the Merger Agreement, a copy of which is filed as Exhibit 2.1 to this Current Report on Form 8-K and is incorporated herein by reference.

The Merger Agreement has been included to provide investors and stockholders with information regarding its terms. It is not intended to provide any other factual information about the Company, Parent or Merger Sub. The Merger Agreement contains representations and warranties that the parties made to and solely for the benefit of each other. The assertions embodied in the representations and warranties in the Merger Agreement are qualified by information contained in the confidential disclosure letter that the Company delivered to Parent in connection with signing the Merger Agreement. This confidential disclosure letter contains information that modifies, qualifies and

creates exceptions to the representations and warranties set forth in the Merger Agreement. Investors are not third-party beneficiaries under the Merger Agreement and should not rely on such representations and warranties as characterizations of the actual state of facts or circumstances. Moreover, information concerning the subject matter of such representations and warranties may change after the date of the Merger Agreement, which subsequent information may or may not be fully reflected in the Company’s or Parent’s public disclosures.
