This Form 3 is being filed on behalf of Hg Investors LLC, a Delaware limited liability company ("Hg Investors") and Igloo
Investors Ltd., a Cayman Islands exempted company and the sole member of Hg Investors ("Igloo" and together with Hg Investors,
the "Reporting Persons"). In connection with the execution and delivery of an agreement and plan of merger, dated as
of May 3, 2010 (the "Merger Agreement"), among the Issuer, Hg Investors and Igloo Merger Corporation, a Delaware corporation
and wholly owned subsidiary of Hg Investors ("Merger Sub"), each of Pearson DBC Holdings Inc. (the "Stockholder"),
Pearson plc and Hg Investors entered into a voting agreement, dated as of May 3, 2010 (the "Voting Agreement"). Pursuant
to the Voting Agreement, the Stockholder agreed to, among other things, vote 57,554,795 shares of common stock of the Issuer
in favor of the merger of Merger Sub with and into the Issuer upon the terms and subject to the conditions set forth in the Merger
Agreement. As a consequence of the Voting Agreement, each of the Reporting Persons may be deemed to have voting power over more than
10% of the common stock of the Issuer. The Reporting Persons do not have, and expressly disclaim, any pecuniary interest in shares
of common stock of the Issuer, and, as a result, no shares of the Issuer's common stock are reported in this Form 3 as being beneficially
