NU Safe Harbor Provisions
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.

Additional Information and Where To Find It
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 are identified and discussed in NSTAR’s and Northeast
Utilities’ reports filed with the SEC and available at the SEC’s website at www.sec.gov.  Forward-looking statements included in this document
speak only as of the date of this document.  Neither NSTAR nor Northeast Utilities undertakes any obligation to update its forward-looking
statements to reflect events or circumstances after the date of this document.
This communication does not constitute an offer to sell or the solicitation of an offer to buy any securities or a solicitation of any vote or approval. 
In connection with the proposed merger between Northeast Utilities and NSTAR, Northeast Utilities filed with the SEC a Registration Statement on
Form S-4 (Registration No. 333-170754)  that includes a joint proxy statement of Northeast Utilities and NSTAR that also constitutes a prospectus
of Northeast Utilities. Northeast Utilities and NSTAR mailed the definitive joint proxy statement/prospectus to their respective shareholders, on or
