SimplexGrinnell Selects Infosys' Supply Chain Visibility & Collaboration Product Suite

Leader in Life Safety and Property Protection to Enhance Sourcing and Procurement Performance

BANGALORE, India and BOCA RATON, Florida, May 25, 2010 - Infosys Technologies Limited (NASDAQ: INFY) and
SimplexGrinnell, a Tyco International company, announced today that
SimplexGrinnell has signed a product license and services agreement to
implement the Infosys Supply Chain Visibility & Collaboration Suite as part
of its enterprise-wide sourcing business intelligence and spend analysis
initiative. SimplexGrinnell will deploy the Sourcing & Procurement module
from the suite in the first phase of the initiative. Other modules are
planned to be deployed in subsequent phases.

With a large strategic sourcing and procurement organization
spread over a network of 150 company-owned offices, SimplexGrinnell sought an
enterprise-level solution to streamline its procurement processes, optimize
its supplier base and reduce procurement spend. The Infosys solution is aimed
at reducing sourcing cycle time and leakages in procurement spend through
enhanced monitoring, compliance and governance mechanisms.

According to Sanjay Lall, CIO and Vice President of
SimplexGrinnell, "We chose the Infosys supply chain solution for its
functional depth and modular approach that can be extended enterprise-wide to
support our goal to reduce procurement spend. The built-in, out-of-the-box
content and performance management features allow quicker deployment at lower
program costs."

The Supply Chain Visibility & Collaboration Suite from Infosys
is built on top of a core platform employing Microsoft technologies,
including SharePoint Server and Office Communications Server, and leverages
the latest in performance management, analytics, collaboration and
event-based management. The suite empowers procurement professionals to
manage the organization's direct and indirect spend by providing visibility
to performance metrics, enabling superior decision making, and improving
associated processes.

Sanjay Jalona, Vice President and Head, Manufacturing North
America, Infosys Technologies, said, "As a large organization with
distributed sourcing and procurement network, SimplexGrinnell is looking to
Infosys for an enterprise-wide solution for greater visibility into spend,
improved collaboration and better performance. The Infosys solution empowers
SimplexGrinnell's procurement teams with contextual intelligence to make good
decisions and collaboration capabilities to act on it."

"In today's global business environment, manufacturers are
increasingly challenged with improving the performance of their supply chain
and enhancing visibility across their offices, suppliers and trading
partners," said Craig Hodges, general manager, U.S. Manufacturing and
Resources Sector, Microsoft. "Infosys's solution incorporates both critical
business intelligence and collaboration capabilities from Microsoft that
enable customers to obtain real insight from information across their
businesses and work quickly as a team to make necessary supply chain
improvements to reduce overall procurement spend."
