   addition, the Company, IES Investments Inc., Clark E. McLeod, Mary E.
   McLeod, Richard A. Lumpkin, Gail G. Lumpkin and certain former CCI
   shareholders and certain permitted transferees of former CCI
   shareholders (collectively, the "1998 Principal Stockholders")are
   parties to a Stockholders' Agreement, dated as of November 18, 1998
   (the "1998 Stockholders' Agreement").  The Company, IES Investments
   Inc., Clark E. McLeod, Mary E. McLeod, Richard A. Lumpkin and Gail G.
   Lumpkin are also parties to a Stockholders' Agreement with M/C
   Investors L.L.C. and Media/ Communications Partners III Limited

   Agreement" and, together with the 1997 Stockholders' Agreement and the
   1998 Stockholders' Agreement, the "Stockholders' Agreements").  The
   other former CCI shareholders who are parties to the 1998
   Stockholders' Agreement, along with certain permitted transferees, are
   expected to become parties to the 1999 Stockholders' Agreement but had
   not yet executed the 1999 Stockholders' Agreement at the time of this
   filing.

             The following table sets forth information regarding the
   shares of Common Stock beneficially owned by the 1997 Principal
   Stockholders (including the Reporting Persons).  Separately set forth
   below are shares beneficially owned by the Reporting Persons and
   others, which shares are not subject to the terms of the Stockholders'
   Agreements.  Except as indicated, beneficial ownership by the Former
   CCI Shareholders reflects their status as trustees of the respective
   trusts set forth opposite their names in the table.  The information
   shown in the table with respect to each 1997 Principal Stockholder who
   is not a former CCI shareholder (the "Other 1997 Principal
   Stockholders") is based on the most recent Schedule 13D or Amendment
   thereto filed by such person that has come to the attention of the
   Reporting Persons.  Reference is made to such filings for further
   information as to such Other 1997 Principal Stockholders.

   shares, to be bound by the terms of the 1997 Stockholders' Agreement. 
   The 1997 Stockholders' Agreement provides that each 1997 Principal
   Stockholder, for so long as such 1997 Principal Stockholder owns at
   least 10% (treating Richard A. Lumpkin and the other Former CCI
   Shareholders as a single 1997 Principal Stockholder for this purpose)
   of the outstanding capital stock of the Company (but in no event
   longer than three years), shall vote such 1997 Principal Stockholder's
   stock and take all action within its power to: (i) establish the size
   of the Board of Directors of the Company at up to eleven directors;
   (ii) cause to be elected to the Board of Directors of the Company one
   director designated by IES (for so long as IES owns at least 10% of
   the outstanding capital stock of the Company); (iii) cause to be
   elected to the Board of Directors of the Company one director
   designated by MHC (for so long as MHC owns at least 10% of the

   long as Mr. Lumpkin and the other Former CCI Shareholders collectively
   own at least 10% of the outstanding capital stock of the Company); (v)
   cause to be elected to the Board of Directors of the Company three
   directors who are executive officers of the Company designated by

   (vi) cause to be elected to the Board of Directors of the Company four
   non-employee directors nominated by the Board of Directors of the

             The 1997 Stockholders' Agreement also provides that, for a
   period which ended September 24, 1998, subject to certain exceptions,
   the 1997 Principal Stockholders (including the Reporting Persons)
   would not sell or otherwise dispose of any equity securities of the
   Company without the consent of the Board of Directors of the Company.

             The foregoing description of the 1997 Stockholders'
   Agreement is qualified in its entirety by reference to the 1997
   Stockholders' Agreement which was filed as an exhibit to the original
   filing of this Schedule and is incorporated herein by reference.

             The 1998 Principal Stockholders and the Company have, with
   respect to the respective shares of capital stock of the Company owned
   by each such 1998 Principal Stockholder, entered into the 1998
   Stockholders' Agreement, effective November 18, 1998.

             The 1998 Stockholders' Agreement provides that until
   December 31, 2001 (the "Expiration Date"), the 1998 Principal
   Stockholders will not offer, sell, contract to sell, grant any option
   to purchase  or otherwise dispose of, directly or indirectly,
   ("Transfer"), any equity securities of the Company, or any other
   securities convertible into or exercisable for such equity securities,
   beneficially owned by such 1998 Principal Stockholder without
   receiving the prior written consent of the Board of Directors of the
   Company, except for certain permitted transfers as provided under the<PAGE>

   1998 Stockholders' Agreement.  The 1998 Stockholders' Agreement
   further provides that the Board of Directors shall determine on a
   quarterly basis commencing with the quarter ending December 31, 1998
   and ending on the Expiration Date, the aggregate number, if any, of
   shares of Common Stock (not to exceed in the aggregate 150,000 shares
   per quarter) that the 1998 Principal Stockholders may Transfer during
   certain designated trading periods following the release of the
   Company's quarterly or annual financial results.

             The 1998 Stockholders' Agreement provides that to the extent
   the Board of Directors grants registration rights to a Principal
   Stockholder in connection with a Transfer of securities of the Company
   by such Principal Stockholder, it will grant similar registration
   rights to the other parties as set forth in the 1998 Stockholders'
   Agreement.  In addition, the 1998 Stockholders' Agreement provides
   that the Board of Directors shall determine on an annual basis
   commencing with the year ending December 31, 1999 and ending on the
   Expiration Date (each such year, an "Annual Period"), the aggregate
   number, if any, of shares of Common Stock (not to exceed in the
   aggregate on an annual basis a number of shares equal to 15% of the
   total number of shares of Common Stock beneficially owned by the 1998
   Principal Stockholders as of December 31, 1998) (the "Registrable
   Amount"), to be registered by the Company under the Securities Act,
   for Transfer by the 1998 Principal Stockholders.  The 1998
   Stockholders' Agreement also provides that in any underwritten primary
   offering (other than pursuant to a registration statement on Form S-4
   or Form S-8 or any successor forms thereto or other form which would
   not permit the inclusion of shares of Common Stock of the 1998
   Principal Stockholders), the Company will give written notice of such
   offering to the 1998 Principal Stockholders and will undertake to
   register the shares of Common Stock of such parties up to the
   Registrable Amount, if any, as determined by the Board.  The 1998
   Stockholders' Agreement provides that the Company may subsequently
   determine not to register any shares of the 1998 Principal
   Stockholders under the Securities Act and may either not file a
   registration statement or otherwise withdraw or abandon a registration
   statement previously filed.

             The 1998 Stockholders' Agreement terminates on the
   Expiration Date.  In addition, if during any Annual Period the Company
   has not provided a 1998 Principal Stockholder a reasonable opportunity
   to Transfer pursuant to the registration of securities under the
   Securities Act or pursuant to certain other provisions of the 1998
   Stockholders' Agreement on the terms therein specified an aggregate
   number of shares of Common Stock equal to not less than 15% of the
   total number of shares of Common Stock beneficially owned by such 1998
   Principal Stockholder as of December 31, 1998, then such 1998
   Principal Stockholder may terminate the 1998 Stockholders' Agreement
   as applied to such 1998 Principal Stockholder within 10 business days
   following the end of any such Annual Period.<PAGE>

             The 1998 Stockholders' Agreement also contains provisions
