This presentation contains statements concerning NU’s expectations, beliefs, plans, objectives, goals, strategies, assumptions of future
events, future financial performance or growth and other statements that are not historical facts.  These statements are “forward-looking
statements”
within the meaning of the Private Securities Litigation Reform Act of 1995.  In some cases, a listener or reader can identify these
forward-looking statements through the use of words or phrases such as “estimate”, “expect”, “anticipate”, “intend”, “plan”, “project”, “believe”,
“forecast”, “should”, “could”, and other similar expressions.  Forward-looking statements are based on the current expectations, estimates,
assumptions or projections of management and are not guarantees of future performance.  These expectations, estimates, assumptions or
projections may vary materially from actual results.  Accordingly, any such statements are qualified in their entirety by reference to, and are
accompanied
by,
the
following
important
factors
that
could
cause
our
actual
results
to
differ
materially
from
those
contained
in
our
forward-
looking
statements,
including,
but
not
limited
to,
actions
or
inaction
of
local,
state
and
federal
regulatory
and
taxing
bodies;
changes
in
business and economic conditions, including their impact on interest rates, bad debt expense and demand for our products and services;
changes in weather patterns; changes in laws, regulations or regulatory policy; changes in levels and timing of capital expenditures;
disruptions
in
the
capital
markets
or
other
events
that
make
our
access
to
necessary
capital
more
difficult
or
costly;
developments
in
legal
or
public policy doctrines; technological developments; changes in accounting standards and financial reporting regulations; fluctuations in the
value of our remaining competitive contracts; actions of rating agencies; the effects and outcome of our pending merger with NSTAR; and
other presently unknown or unforeseen factors. Other risk factors are detailed from time to time in our reports to the Securities and Exchange
Commission (SEC).  Any forward-looking statement speaks only as of the date on which such statement is made, and we undertake no
obligation to update the information contained in any forward-looking statements to reflect developments or circumstances occurring after the
statement is made or to reflect the occurrence of unanticipated events.
This presentation references actual and projected EPS by business.  EPS by business is a non-GAAP (not determined using generally
accepted accounting principles) measure that is calculated by dividing the net income or loss attributable to controlling interests of each
business
by
the
weighted
average
diluted
NU
parent
common
shares
outstanding
for
the
period.
Management
uses
this
non-GAAP
financial
measure to evaluate earnings results and to provide details of earnings results and guidance by business.  This presentation also includes
non-GAAP
financial
measures
referencing
our
2006
-
2010
EPS
excluding
a
number
of
factors
that
affected
GAAP
earnings
in
those
years.
In
addition, our 2011 earnings guidance excludes certain non-recurring charges related to merger costs we expect to incur during 2011, which is
a non-GAAP financial measure.  Management believes that these non-GAAP financial measurements are useful to investors to evaluate the
actual and projected financial performance and contribution of NU’s businesses.  Non-GAAP financial measures should not be considered as
alternatives to NU consolidated net income attributable to controlling interests or EPS determined in accordance with GAAP as indicators of
NU’s operating performance.

Information Concerning Forward-Looking Statements Relating to the NU–NSTAR Merger
In
addition
to
historical
information,
this
communication
may
contain
a
number
of
“forward-looking
statements”
as
defined
in
the
Private
Securities
Litigation
Reform
Act
of
1995.
Words
such
as
anticipate,
expect,
project,
intend,
plan,
believe,
and
words
and
terms
of
similar substance used in connection with any discussion of future plans, actions, or events identify forward-looking statements. 
Forward-looking statements relating to the proposed merger include, but are not limited to: statements about the benefits of the
proposed merger involving NSTAR and Northeast Utilities, including future financial and operating results; NSTAR’s and Northeast
Utilities’
plans, objectives, expectations and intentions; the expected timing of completion of the transaction; and other statements
relating to the merger that are not historical facts.  Forward-looking statements involve estimates, expectations and projections and, as
a
result,
are
subject
to
risks
and
uncertainties.
There
can
be
no
assurance
that
actual
results
will
not
materially
differ
from
expectations. 
Important factors could cause actual results to differ materially from those indicated by such forward-looking statements.  With respect
to
the
proposed
merger,
these
factors
include,
but
are
not
limited
to:
the
risk
that
NSTAR
or
Northeast
Utilities
may
be
unable
to
obtain
governmental and regulatory approvals required for the merger, or required governmental and regulatory approvals may delay the
merger
or
result
in
the
imposition
of
conditions
that
could
reduce
the
anticipated
benefits
from
the
merger
or
cause
the
parties
to
abandon the merger; the risk that a condition to closing of the merger may not be satisfied; the length of time necessary to consummate
the proposed merger; the risk that the businesses will not be integrated successfully; the risk that the cost savings and any other
synergies from the transaction may not be fully realized or may take longer to realize than expected; disruption from the transaction
making it more difficult to maintain relationships with customers, employees or suppliers; the diversion of management time on merger-
related
issues;
the
effect
of
future
regulatory
or
legislative
actions
on
the
companies;
and
the
risk
that
the
credit
ratings
of
the
combined
company
or
its
subsidiaries
may
be
different
from
what
the
companies
expect.
These
risks,
as
well
as
other
risks
associated
with
the
merger, are more fully discussed in the joint proxy statement/prospectus that is included in the Registration Statement on Form S-4
(Registration No. 333-170754) that was filed by Northeast Utilities with the SEC in connection with the merger.  Additional risks and
uncertainties
