TOKYO -- July 3, 2013

Toshiba Corporation (TOKYO:6502) today announced that it has received a major
order from Singapore railway operator, SMRT Corporation (SMRT), for Permanent
Magnet Synchronous Motors (PMSM) for the refurbishment of existing drive
systems of 66 C151 series train sets, consisting of 6 cars, a total of 396
cars. This is the first deployment of the high efficiency PMSM outside Japan,
and Toshiba will use it as a springboard to winning further orders in the
global market.

SMRT runs the 66 C151 series trains on two major commuter lines in Singapore's
Mass Rapid Transport system: the 45-kilometer North-South Line running between
Jurong East and Marina Bay and the 57k East-West Line running between Pasir
Ris and Joo Koon. The trains are electric multiple units without a separate
locomotive, driven by electric traction motors in one or more cars; in four of
six cars in the C151 series. The SMRT trains entered service in 1987, and this
is the first upgrade to their drive systems.

The drive systems will include Toshiba-developed PMSM and peripheral
equipment. They will cut power consumption by 30%, reduce operating noise
levels, and improve the operating efficiency of the trains. They will first be
installed on two train sets in early 2015, and subsequently in others
following 1-2 years of test runs.

With increasing urbanization and crowded city roads, rail is once again being
recognized as an environmentally friendly, high efficiency, low noise, easily
maintained mass transport solution. Toshiba developed PMSM as a power and
noise efficient drive system for commuter trains, and it has already been
introduced on trains operating on the world's busiest subway network, Tokyo
Metro, including the Chiyoda Line, the Marunouchi Line and the Ginza Line.

Building on its record in Japan, Toshiba is now promoting a global expansion
of its railway business by proposing its environmental friendly PMSM drive
system and other products and systems to rail transport operators around the
