Vote for the Merger.

Cover with Caption: "If the Merger is approved and completed, you will receive
at least $31 in cash for each EUA share you own. That's a 23% premium over the
$25.1875 closing price of EUA shares on December 4, 1998, the last trading day
prior to other regional utility merger announcements which affected EUA's share
price."

Dear Fellow Shareholder:

Over the past few years the electric utility industry in Massachusetts and
Rhode Island has undergone a dramatic transition from the passing era of
regulated monopolies to a more dynamic age of competition, particularly in the
electric generation business. As active participants in this transition, our
over-riding mission remained clear-maximizing shareholder value. We believe our
recent actions, including the proposed merger of EUA and New England Electric
System (NEES), do just that.

We recently mailed you a proxy statement regarding the Merger with NEES. This
brochure provides a brief review of some of the key information included in the
proxy, but we urge you to read the proxy statement carefully. The proxy
statement contains all the important information you need to consider the
Merger.

Your Board of Trustees believes that the Merger is in the best interests of EUA
and its shareholders and has unanimously recommended a vote FOR approval of the
Merger.

We urge you to return the enclosed proxy card today with a vote FOR approval of
the Merger. If you have any questions about the Merger or need any assistance
in voting your shares, please call the company helping us solicit proxies -
Innisfree M&A Incorporated, toll-free at 1-888-750-5834.


Sincerely,


/s/Donald G. Pardus                     /s/John R. Stevens
Donald G. Pardus                        John R. Stevens
Chairman of the Board                   President and
and Chief Executive Officer             Chief Operating Officer

Basics of the Proposed Merger

EUA has agreed to merge with NEES, New England's second largest electric
utility company headquartered in Westborough, Massachusetts. This combination
will bring together two of New England's lowest cost utilities and achieve even
greater cost saving s for customers. EUA and NEES share a long history of
providing customers with high quality service and low rates, and the Merger is
a natural fit in philosophy, geography and corporate structure. Upon completion
of the Merger, the combined company w ill serve 1.7 million electricity
customers in 228 New England communities.

a vote FOR approval of the Merger."


NEES subsidiaries are engaged in the transmission and distribution of
electricity and the marketing of energy commodities and services. The
electricity delivery companies serve 1.4 million customers in Massachusetts,
Rhode Island and New Hampshire.

A Significant Premium for EUA Shareholders - $31 per Share

NEES will acquire EUA at a price of $31 per share. That price represents a 23%
premium above the price of EUA shares on December 4, 1998 (the last trading day
before other regional merger announcements affected EUA's share price), and a
5% premium above the closing price on January 29, 1999 (the last day of trading
on the New York Stock Exchange before the Merger was announced).

You will receive $31 in cash for each EUA share you own. That amount would be
increased by $.003 per day, beginning six months after EUA shareholders approve
the Merger and continuing until the Merger is completed, up to a maximum price
of $31.495 per share.

You will continue to receive dividends at the current level as declared by the
Board of Trustees until the Merger is accomplished.

After the Merger is completed, we will send you information on how to turn in
your share certificates for the appropriate per share cash payment. You will
then have the freedom to reinvest that cash in the manner most appropriate for
your financial circumstances.

Board of Trustees Recommends a "FOR" Vote

Your Board carefully considered the dramatic changes in the electric utility
industry, analyzed EUA's current and future financial prospects, and reviewed
all options available to EUA, including, among other things, continuing as a
stand-alone company and other merger options.

The Board concluded that the Merger at this time would be fair to, and in the
best interest of, EUA and its shareholders.

The Board unanimously recommends that shareholders vote FOR approval of the
Merger by signing, dating and returning the enclosed proxy.

Remember, not returning your proxy card or abstaining has the effect of a vote
against the Merger.

Voting for the Merger Proposal

Approval of the Merger requires a FOR vote from 2/3 of all common shares.
Therefore, your vote is extremely important since not voting has the effect of
a vote against the Merger. EUA's Board and management team urge you to vote
FOR the Merger today!  To do this, sign and return the enclosed proxy card in
the postage-paid envelope provided. Please return the signed proxy card today
so that your shares may be represented at the annual shareholders meeting.

If you decide later to change your vote, you can do so at any time up to and at
the EUA Annual Meeting, which is scheduled to be held in the Board Room on the
33rd floor of the State Street Bank and Trust Company, 225 Franklin Street,
Boston, Massachusetts, at 9:30 a.m. on Monday, May 17, 1999.
