CSC’s VANTAGE-ONE System Enhanced for Japanese Market; Manulife’s Japanese Subsidiary First to Use Annuity System

EL SEGUNDO, Calif., June 4 — Computer Sciences Corporation (NYSE: CSC) today announced that it has enhanced its VANTAGE-ONE(R) insurance and annuity administration system to support Japanese business requirements.

Manulife Life Insurance Company (Japan), a subsidiary of
Manulife Financial Corporation (NYSE: MFC) headquartered in Toronto, Ontario, is the first
annuity user of the enhanced system, which is supporting Manulife’s recently introduced
“ManuSolution” annuity. ManuSolution is one of Japan’s first tax-deferred, investment-type annuities.

CSC’s VANTAGE-ONE system administers more than half of the
variable annuity policies sold in the U.S. To meet Japan’s business requirements, CSC
tailored VANTAGE-ONE to support Japanese-language data storage, displays, transactions and
reports, as well as Yen currency and tax compliance. CSC manages and operates the Japanese
version of VANTAGE-ONE at its San Diego, Calif., data center, in support of Manulife’s employees in Japan.

“Manulife aspires to be the most professional life
insurance company in Japan,” said Trevor Matthews, president and chief executive
officer of Manulife Japan. “We are known as a leading provider of innovative
products, and CSC helped us import that capability into our Japanese operation. CSC used
its knowledge of annuities, Manulife and local requirements to deliver our Japanese
annuity platform on time in less than one year.”

Supporting languages like Japanese, which uses a complex
character set, requires fundamental architectural changes to computer systems built for
languages that use Latin letters, such as English. Working with Manulife, CSC enhanced
VANTAGE-ONE to support the complex character set, called “double-byte character set” or
DBCS. With the enhancement, CSC can now readily adapt the system to support other Asian languages.

“CSC has extensive experience providing insurance
software for the Japanese market and has supported Manulife USA’s annuities for more than
15 years,” said Jim Cook, president of CSC’s Financial Services Group.

“Helping Manulife execute its strategy in Japan is a
logical extension of our relationship. With this product enhancement, we are pleased to
bring another market-leading processing platform to Asia.”
