Alstom and Infosys Technologies Partner to Develop Next Generation Power Solutions

Focus on High-end Engineering and R&D Services

NEW DELHI, May 11, 2010 - Alstom, a world leader in energy and rail transport
infrastructure and Infosys Technologies Limited (NASDAQ: INFY), today
announced the expansion of their strategic partnership in areas of global
Research and Development (R&D), Engineering and Engineering IT services. This
partnership envisages substantial strategic investments over the next five
years to develop next generation solutions for the power sector.

Infosys will provide support to Alstom Power's global business
units in core business areas including Product Development, Simulation,
Product Lifecycle Management (PLM), and Engineering IT. Infosys will also
support Alstom in building knowledge management processes for its design and
engineering teams. This collaborative operating model will enable Alstom to
benefit from faster time-to-market for new products, customization and
adaptation of existing products for emerging markets, while also sustaining
its current offerings.

"We see this long-term technological partnership with Infosys,
a leader in Information System Technology, as one of the key drivers to
developing the next generation of Alstom's power solutions," said Mr.
Philippe Joubert, President, Alstom Power. "Given our experience with Infosys
and our confidence in their strong competencies, they are a natural partner
of choice. This endeavor also underlines our commitment to invest in Asia,
particularly in India."

This engagement builds upon the existing relationship between
Alstom and Infosys, which began in 2005 with the establishment of the Alstom
R&D Center at the Infosys campus in Mysore and now extends to all of Alstom
Power's business units. Most recently, an additional Alstom R&D center has
been established at the Infosys campus in Pune.

"Infosys has invested in engineering and technology specific
centers-of-excellence to support Alstom Power globally," said Mr. BG
Srinivas, Member of Infosys' Executive Council. "As Alstom Power strengthens
its focus on emerging markets, we have been able to combine our deep
understanding of their business and engineering processes with our extensive
knowledge of these markets to function as an innovation hub for Alstom."
