THE MARKET OPPORTUNITY
Network "Levels" in Germany
================================================================================

>     Network level ownership in Germany is split - whereas the former DT
      networks control the vast majority of head-end connections in Germany,
      they only control a minority of subscriber relationships (Level 4)

>     New PrimaCom, in contrast, will control the majority of its subscriber
      relationships and will be building "upstream" capacity

INVESTMENT HIGHLIGHTS
New PrimaCom Upgrade Strategy
================================================================================

- --------------------------------------------------------------------------------
PrimaCom's network upgrade program will benefit from the improved scale and
clustering resulting from the combination of PrimaCom and EWT/tss
- --------------------------------------------------------------------------------

>     Focus on most densely-populated clusters in the core operating regions

      -     Larger number of clusters through EWT/tss (Telecolumbus option
            subscribers are also located in core regions)

>     Upgrades in Leipzig, Magdeburg, Chemnitz, Halle, Aschersleben, Naumburg
      and Mainz already largely completed

      -     PrimaCom upgrade program can easily be expanded to EWT/tss
            subscribers

>     Existing and planned fibre passes EWT/tss clusters, which can be directly
      connected

>     Pass new homes in upgraded cities and grow subscriber base

      -     Increased reach through additional fibre

>     Consolidate DTAG interconnection points and reduce signal delivery fees

      -     Significant further consolidation potential due to overlap of
            footprints

>     Reduce capital expenditure requirements by exploiting improved clusters


                                                                              21

INVESTMENT HIGHLIGHTS
Upgrade Economics due to Density: Chemnitz Example
================================================================================

- --------------------------------------------------------------------------------

>     High fixed cost element (server, backbone infrastructure) means that there
      are significant capex synergies available from increasing subscriber
      density

>     Related synergies: maintenance, marketing of new services

FINANCIAL ANALYSIS
Synergy Potential
================================================================================

>     The business combination with EWT/tss creates significant cost and capex
      savings potential compared to a stand-alone strategy

ILLUSTRATIVE P&L SYNERGY POTENTIAL:

EWT ARPU normalization                 EWT analog CATV rates artificially low; no rate regulation

DT signal fee reduction                Connect EWT's subscribers to PrimaCom's broadband
                                       networks (where feasible)

Overhead savings                       Duplicate overhead organizations

ILLUSTRATIVE CAPEX SYNERGY POTENTIAL:

Upgrade capex savings                  Improved clustering creates feasible scale (allocation of
                                       fixed upgrade costs to subscribers)

FINANCIAL ANALYSIS
Financing Strategy
================================================================================

>     Based on the existing forecast assumptions, PrimaCom's business plan is
      fully funded for the build-out of core regions in the combined networks
      and the launch of digital services to the existing subscriber base

>     Larger cash acquisitions would require additional financing

>     Will consider using own shares as acquisition currency on a case-by-case

FINANCIAL ANALYSIS
M&A Strategy
================================================================================

>     PrimaCom intends to use its enhanced strategic position in the German
      market to continue to make value-adding acquisitions in a highly
      fragmented market environment

      -     Intends to use own shares as acquisition currency as appropriate

>     Fill-in acquisition opportunities are available in PrimaCom's core regions

>     The TeleColumbus option is currently being evaluated

>     Clear focus on Germany

>     Liberty Media (UPC's indirect majority shareholder) is currently acquiring
      six DT cable regions with over 10 million subscriber relationships (3
      million direct / 7 million indirect), including the regions of Sachsen /
      Sachsen-Anhalt / Thuringen and Berlin / Brandenburg
