On January 26, 2012, RealNetworks, Inc. (the “Company”) entered into an Asset Purchase Agreement (the “Asset Purchase Agreement”) with Intel Corporation (“Intel”). Pursuant to the Asset Purchase Agreement, Intel will acquire certain patents, patent applications and related rights held by the Company (the “Patent Assets”) and certain assets of the Company relating to its Next Generation Video codec technologies (the “Codec Assets”), in exchange for cash consideration of $120,000,000 and the assumption of certain liabilities of the Company, subject to the potential adjustments provided for in the Asset Purchase Agreement (the “Asset Sale”).

The Asset Purchase Agreement contains representations and warranties by the Company regarding the Patent Assets and Codec Assets and other representations and warranties by the Company and Intel customary for transactions of this nature, covenants by the Company regarding the operation of its business in relation to the Patent Assets and Codec Assets between the date of signing of the Asset Purchase Agreement and the closing date of the Asset Sale, and indemnification provisions whereby each party will indemnify the other party and its affiliates and representatives for breaches of representations and warranties, breaches of covenants and certain other matters.

The consummation of the Asset Sale is subject to closing conditions, including the expiration or termination of the applicable waiting period, if required, under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, and any similar requirements that may exist under the competition and merger control laws of the Republic of Korea. The Asset Sale is expected to close in the first calendar quarter of 2012.

Concurrently, and in connection with entering into the Asset Purchase Agreement, the Company and Intel have also entered into a license agreement (the “License Agreement”), pursuant to which the Company will obtain a non-exclusive, royalty-free, fully paid up, irrevocable (except as set forth in the License Agreement) and worldwide license (without the right to grant sublicenses) under the Patent Assets for use in connection with the Company’s businesses. The transferability of the License Agreement is limited in the event of a change of control or character of the Company, as set forth in the provisions attached as Exhibit C to the License Agreement.

The foregoing descriptions of the Asset Purchase Agreement and License Agreement do not purport to be complete and are qualified in their entirety by reference to the Asset Purchase Agreement and License Agreement, attached as Exhibit 2.1 and Exhibit 10.1, respectively, to this Current Report on Form 8-K and incorporated herein by reference.
