Subject to the terms and conditions of the Merger Agreement, Reporting Person stockholders will be able to elect to receive either $2.42 in cash or 0.2659 shares of Holdco common stock for each share of Reporting Person stock, subject to proration, upon the consummation of the Company Merger.

The Irrevocable Proxy (i) does not give ownership of the shares of Common Stock owned directly or indirectly by the Stockholders to the Reporting Person, and (ii) is subject to certain limitations, as set forth in the Voting and Waiver Agreement. The Irrevocable Proxy will terminate and be of no further force and effect on the earlier to occur of (i) the Effective Time (as such term is defined in the Merger Agreement), (ii) the date on which the Merger Agreement is terminated in accordance with its terms (including any extensions to the Merger Agreement, as provided for therein), (iii) December 31, 2003, or (iv) with respect to any shares owned by Stockholder, including any Securities (as defined in the Voting and Waiver Agreement) held by any Stockholder sold, transferred or otherwise disposed of to any transferee other than, with respect to CBS, a controlled affiliate of Viacom Inc., and with respect to PIFL, a controlled affiliate of Pearson plc, the time of effectiveness of such sale, transfer or disposition. The Voting and Waiver Agreement is filed as Exhibit 10.1 hereto. Pursuant to the Voting and Waiver Agreement, the Stockholders agreed (i) to vote such Stockholder's shares of Common Stock in favor of the transactions contemplated by the Merger Agreement at a meeting of the Issuer's stockholders called for the purpose of securing stockholder approval of the transactions contemplated by the Merger Agreement, (ii) not to enter into any agreement or understanding inconsistent with the Voting and Waiver Agreement, and (iii) waive their participation right to purchase additional Holdco securities to maintain their respective percentage ownership.
