Temporary worker Briefing

• You may be aware that ntl and Telewest announced today a definitive merger agreement under which ntl will acquire Telewest. This creates the U.K.’s second largest communications company and leading triple play service provider.
  
  
• As a temporary worker you’re very important to Hays and ntl and so we wanted to make sure you were aware of this as soon as possible.
  
  
• We believe the proposed acquisition - the last step in the consolidation of the UK’s cable industry - will create a business with the scale and resources to fully utilise the unique capabilities of cable.
  
  
• The benefits will be felt through intensified competition across the pay TV, telephony and Internet access markets. We’d also hope to accelerate the delivery of next generation entertainment, business and public services.
  
  
• In a nutshell, we’ll be better positioned to meet the future needs of customers.
  
  
• However, for now, nothing changes. It’s business as usual for ntl and Telewest.
  
  
• The transaction is subject to agreement by shareholders. There are also some important regulatory and other steps that have to be satisfied before the deal can be closed. This could take up to several months, depending on how we progress through the process.
  
  
• The OFT and OFCOM are aware of the transaction. Formal notification containing detailed information about the transaction and the operations of both companies will be submitted to both organisations shortly.
  
  
• The OFT will review possible implications of the proposed deal and either approve or refer it to the Competition Commission for more detailed review. Whatever happens we’ll keep you informed.
  
  
• At this early stage there isn’t much more to add. We wanted to make sure you were informed personally.
  
  
• For further information please see the associate Q & A on the ntl intranet (to be posted shortly). If you have any further questions please do not hesitate to contact your local Hays On-site co-ordinator.
  
  
• Hope you agree this is an exciting time for ntl and the start of a new era for UK cable.
