- Seven-year Agreement Extends CSC's Relationship with Denmark's Leading Telecommunications Provider

Computer Sciences Corporation (NYSE: CSC) announced today that it has signed a new, seven-year information technology (IT) applications outsourcing agreement with TDC, the largest telecommunications company in Denmark. The contract is valued at approximately US$413 million.

CSC has supported TDC since 2003. The new agreement follows last year's US$330 million, seven-year award, which expanded the scope of infrastructure services CSC was providing. Under the new contract, which substantially expands CSC's application services support, CSC will manage TDC's legacy application portfolio, providing application development and maintenance services for more than 500 applications and supporting approximately 17,000 users.

As part of the new agreement, approximately 220 TDC employees will transition to CSC in June.

"We already have an excellent relationship with CSC in several areas and are pleased to expand it further to include the management of our legacy application portfolio," said Jorgen Jakobsen, TDC chief information officer. "The new agreement will enable us to further modernize and consolidate our applications so they deliver the capabilities our business requires."

"We are delighted to grow our relationship with TDC," said Guy Hains, president of CSC's European Group. "During the past five years our support has continued to evolve and provide enhanced value. Signing this new agreement is testament to that fact. We look forward to collaborating on this critical program and continuing to serve TDC in ways that provide the agility, innovation and performance the company needs to support its business agenda."
