AGREEMENT

EXHIBIT 10.8

AGREEMENT

THIS AGREEMENT is made as of June 18, 2004 between and among Viacom Inc. (“Viacom”), Paramount Home Entertainment, Inc. (sued as Paramount Home Video, Inc.), and Sumner Redstone (collectively, “Viacom Entities”) and Blockbuster Inc. (“Blockbuster”) (Viacom Entities and Blockbuster collectively, “Parties”), each of which is a party to a judgment sharing agreement (“Judgment Sharing Agreement”) made as of November 9, 2001 between and among certain defendants in Cleveland, et al. v. Viacom Inc., et al., No. SA-99-CA-0783 in the United States District Court for the Western District of Texas or in Merchant, et al. v. Redstone, et al., No. BC 244 270 in the Superior Court for the State of California, County of Los Angeles.

Section 1. Preamble

WHEREAS Viacom was Blockbuster’s parent at the time the Judgment Sharing Agreement was made and signed.

WHEREAS Viacom presently intends to split off Blockbuster, with the result that Viacom will no longer be Blockbuster’s parent.

WHEREAS the Judgment Sharing Agreement did not differentiate between the Viacom Entities and Blockbuster in the percentage allocations in Exhibit A thereof and instead allocated to the Viacom Entities and Blockbuster a unitary share because the Viacom Entities and Blockbuster were adjudged by the court in Cleveland, et al. v. Viacom Inc., et al. to have been incapable of conspiring with each other for purposes of antitrust laws and thus to have a unity of interest at all times relevant to the Revenue Sharing Antitrust Cases.

WHEREAS the Parties wish to provide for an equitable apportionment among themselves of the unitary share which might arise out of the Revenue Sharing Antitrust Cases (by judgment or by operation of the Judgment Sharing Agreement), to establish a process for the possible settlement of their unitary interest in the Revenue Sharing Antitrust Cases, and to avoid controversy, dispute or litigation among themselves with respect thereto.

NOW, THEREFORE, for the foregoing and other good and valuable consideration, the receipt and sufficiency of which is hereby acknowledged, the Parties agree as follows:

Section 2. Definitions

Unless defined in this Agreement, capitalized terms shall have the meaning ascribed to them in the Judgment Sharing Agreement.

Section 3. Allocation of Obligations Under Judgment Sharing Agreement

3.1 The Viacom Entities and Blockbuster shall be responsible for satisfying any liability incurred by either party that arises out of the Revenue Sharing Antitrust Cases by judgment or by operation of the Judgment Sharing Agreement in accordance with the following percentages: Viacom Entities 66.67% and Blockbuster 33.33%.

Section 4. Settlement

4.1 No party may reach an agreement of Settlement in the Revenue Sharing Antitrust Cases without the consent of the other party, such consent not to be unreasonably withheld by either party.

4.2 Each party shall cooperate in any settlement discussions in a Revenue Sharing Antitrust Case, including by disclosing all settlement discussions between a party and a Claimant or Claimants.

representation or inducement (whether material, false, negligently made or otherwise) of any other party with respect to said party’s decision to execute this Agreement.

5.4 Whenever possible, each provision of this Agreement shall be interpreted in such a manner as to be effective and valid under applicable law. If any portion of this Agreement is declared invalid for any reason in any jurisdiction, such declaration shall have no effect upon the remaining portions of this Agreement, which shall continue in full force and effect as if this Agreement had been executed with the invalid portions thereof deleted; provided, that the entirety of this Agreement shall continue in full force and effect in all other jurisdictions.
