Explanation of Responses:

1. These shares are owned directly by Shivers Investments, LLC, which is a wholly owned subsidiary of Morris Communications Holding Company, LLC ("Holding"), which is a wholly owned subsidiary of Shivers Trading & Operating Company ("STO"). Holding and STO are indirect beneficial owners of the reported securities.

Remarks:

(2) Morris Communications Company, LLC, formerly Morris Communicatons Corp.("MCC"), is a wholly owned subsidiary of Holding. On June 29, 2007, MCC distributed 100% of its membership interest in Shivers Investments, LLC to Holding, with no consideration. As a result, Shivers Investments, LLC is now wholly owned by Holding, and both MCC and Shivers Investments, LLC are "brother-sister" subsidiaries of Holding. Shivers Investments, LLC directly owns 28,309,674 shares of Class A Common Stock of Mediacom Communications Company. After this transaction, MCC no longer beneficially owns these securities, although the ultimate beneficial ownership of these securities has not changed, since each of STO, Holding, Shivers Investments, LLC and MCC are still controlled by William S. Morris and his wife.
