               Mediacom Broadband LLC Announces Agreement to Sell
             $300 Million Principal Amount of Senior Notes due 2015

Middletown,  NY --  September  29, 2006 -- Mediacom  Broadband  LLC and Mediacom
Broadband  Corporation,  wholly-owned  subsidiaries  of Mediacom  Communications
Corporation (NASDAQ:  MCCC),  announced today that they have agreed to sell $300
million  principal  amount of 8-1/2% senior notes due 2015 (the "Senior Notes").
Mediacom Broadband LLC and Mediacom Broadband  Corporation  initially  announced
that they  intended to offer $200 million  principal  amount of Senior Notes but
increased  the size of the  offering  in order to meet excess  demand.  Mediacom
Broadband  LLC will use the net  proceeds of the  offering to reduce  borrowings
(but not  commitments)  outstanding  under the revolving  credit  portion of its
subsidiary credit facility.

The Senior  Notes will be offered to qualified  institutional  buyers under Rule
144A and to persons  outside the United  States under  Regulation  S. The Senior
Notes will not be registered  under the  Securities Act of 1933, as amended (the
"Securities Act"), and, unless so registered,  may not be offered or sold in the
United States  except  pursuant to an exemption  from,  or in a transaction  not
subject to, the  registration  requirements of the Securities Act and applicable
state securities laws. This press release shall not constitute an offer to sell,
or the  solicitation of an offer to buy, the Senior Notes nor shall there be any
sale of the Senior Notes in any state in which such offer, solicitation, or sale
would be unlawful prior to  registration or  qualification  under the securities
laws of any such state.

Any  statements  in this  press  release  that  are  not  historical  facts  are
forward-looking  statements  within the meaning of Section 21E of the Securities
Exchange Act of 1934, as amended.  These forward-looking  statements are subject
to risks and uncertainties  that could cause actual results to differ materially
from historical  results or those Mediacom  Broadband LLC and Mediacom Broadband
Corporation anticipate. For a discussion of such risks and uncertainties,  which
could cause actual results to differ from those contained in the forward-looking
statements,  see the reports and documents  Mediacom  Broadband LLC and Mediacom
Broadband  Corporation  file from time to time with the  Securities and Exchange
Commission. Statements included in this press release are based upon information
known to Mediacom  Broadband LLC and Mediacom  Broadband  Corporation  as of the
date of this press release,  and Mediacom  Broadband LLC and Mediacom  Broadband
Corporation  assume no obligation to (and expressly disclaim any such obligation
to) publicly update or alter their forward-looking statements made in this press
release,  whether as a result of new  information,  future  events or otherwise,
except as otherwise required by applicable federal securities laws.
