Northern Trust Appointed by West Sussex Pension Fund for GBP1.5 Billion Custody Mandate

Win underlines Northern Trust's commitment to local government pension schemes

LONDON, April 8, 2010 - Northern Trust (Nasdaq: NTRS) has been appointed to provide global
custody and investment accounting services to approximately GBP1.5 billion
(US$2.23 billion) in pension fund assets for West Sussex Pension Fund, one of
the largest pension funds in the UK.

This follows Northern Trust's appointment in 2009 to provide custody
services to the Parliamentary Contributory Pension Scheme and the Royal
Borough of Kensington and Chelsea pension scheme. Northern Trust also acts as
global custodian for the Strathclyde Pension Fund, the largest local
government pension scheme in the United Kingdom.

"We appointed Northern Trust following a competitive tender process,"
said Rachel Wood, Pension Fund Investment Strategist at West Sussex Pension
Fund. "Northern Trust worked closely with us to understand our specific
requirements and designed a cost-effective and technologically efficient
solution tailored to our needs."

"Our appointment as custodian to the West Sussex Pension Fund further
highlights Northern Trust's continued success in, and commitment to, serving
local government pension schemes," said Douglas Gee, UK institutional sales
manager for asset servicing at Northern Trust. "We understand our pension
scheme clients are looking for solutions including, and beyond, custody, such
as access to expertise and information on pensions, investments and
government and regulatory issues, as well as proprietary research into
market-related issues such as risk management and fiduciary management.
Northern Trust's Retirement Solutions Practice brings expertise, knowledge
and experience together to ensure this type of information is even more
accessible to our clients."

Northern Trust provides custody and related services to approximately
one-third of the top 200 pension funds in the UK and one-third of all UK
local government pension funds. Northern Trust's UK pension fund custody
business grew significantly in 2009, with 10 new clients in this segment
alone.
