                              STRATEGIC COMBINATION

           COMBINES COMPLEMENTARY STRENGTHS AND GEOGRAPHIES TO CREATE
                       A LEADING NORTHEAST ENERGY COMPANY

                       TRANSACTION VALUED AT $1.4 BILLION


Albany, NY and Rochester, NY (February 20, 2001) - Energy East Corporation
(NYSE: EAS) and RGS Energy Group, Inc. (NYSE: RGS) today announced that their
boards of directors have unanimously approved a definitive merger agreement,
under which all of the outstanding shares of RGS Energy will be exchanged for a
combination of cash and Energy East stock valued at $39.50 per RGS Energy share
or approximately $1.4 billion in the aggregate. Energy East will also assume
approximately $1.0 billion of RGS Energy debt. Energy East intends to finance
the cash portion of the transaction primarily through third party financing.

The transaction will be accounted for as a purchase and is expected to be
accretive to Energy East's earnings per share in the first full year after
closing. The companies anticipate that approval from the New York State Public
Service Commission can be obtained on an expedited basis, and all regulatory
approvals can be obtained in approximately 12 months.

The combined company will be one of the largest, most diversified energy
providers in the Northeast, serving nearly 3 million customers, including
approximately 1.8 million electric customers, almost one million natural gas
customers and approximately 200,000 other retail energy customers. The combined
company will have annual revenues of approximately $5 billion and nearly $10
billion in assets. Together, Energy East and RGS Energy, through their operating
subsidiaries, will serve half of upstate New York.

Wes von Schack, chairman, president and chief executive officer of Energy East,
said, "RGS Energy and Energy East share a common vision for upstate New York.
Simply put, we are focused on providing our customers a reliable supply of
electricity and stable prices during these challenging times in the energy
marketplace. RGS Energy's proven management and operational talent will fortify
our own, and we look forward to working with Tom Richards and the RGS Energy
team. RGS Energy is the right partner, at the right time.

"Over the last few years, Energy East has been working to become a
super-regional energy delivery and services company, building a presence in 5
northeastern states. By combining with RGS Energy, we are becoming the premier
upstate energy utility, while also strengthening our overall presence in the
Northeast, adding to our generation portfolio and offering attractive returns to
our shareholders. Rochester Gas & Electric's (RG&E) service territory is an
excellent fit with New York State Electric & Gas (NYSEG), with over 200 miles of
contiguous territory providing the opportunity for operational efficiencies.
Through NYSEG's long-term contracts and owned generation, NYSEG has supply
certainty through March 2003. RG&E supplies its customers' requirements
substantially through its own generation portfolio. Together, we will be able to
provide price stability for upstate New York," Mr. von Schack added.

Tom Richards, chairman, president and chief executive officer of RGS Energy,
said, "RGS Energy and Energy East are committed to managing the transition to a
restructured industry in order to create both short and long-term benefits for
our customers and the upstate region. Already, we are working together to design
rate plans that provide reliable energy at stable prices, while continuing to
encourage competition by offering customers a choice in their energy provider.
Together, we will have a wide range of options for meeting customers' supply
requirements, including long-term contracts, owned generation and selective
generation build-out. I am convinced that combined, we have the scale and scope
to provide benefits for our shareholders, our customers, our employees and the
communities we serve.

"We intend to be a reason why upstate New York is successful. We are
particularly excited about the opportunities that our combination will bring to
this region. Providing service to half of upstate New York, we are committed to
the economic vitality of the region as a platform for growth for our combined
company. With approximately 5,000 employees in upstate New York, the combined
company has a track record of community involvement and corporate contributions.
These will remain priorities," concluded Mr. Richards.

TERMS

Under the terms of the agreement, RGS Energy shareholders would receive the
equivalent of $39.50 for each share of RGS Energy common stock they own, payable
in cash or in Energy East common stock, so long as Energy East's common stock
price is between $16.57 and $22.41. Each RGS Energy shareholder would be able to
elect the form of consideration they wish to receive, subject to proration so
that 55 percent of the RGS Energy shares would be exchanged for cash, and 45
percent would be exchanged for Energy East common stock. The stock portion of
the consideration is expected to be tax free to RGS Energy shareholders.

Each RGS Energy share, converted into Energy East common stock, would receive
not less than 1.7626 and not more than 2.3838 shares of Energy East common
stock, depending on the average closing price of Energy East stock during a
20-day trading period prior to the merger closing. For example, based on Energy
East's closing price of $19.14 on February 16, 2001, RGS Energy shareholders who
choose to receive common stock would receive 2.0637 Energy East shares for each
RGS Energy share.

The combined company expects to maintain Energy East's dividend policy. The
Energy East dividend has been increased 5 percent in each of the last three
years. Energy East's current annual common stock dividend is $0.92 per share.
Based on Energy East's closing stock price on February 16, 2001, RGS Energy
shareholders who choose to receive Energy East common stock would receive 2.0637
Energy East shares for each RGS Energy share. This would represent a converted
dividend equivalent of $1.90 per share, an increase over the $1.80 per share
dividend that RGS Energy shareholders currently receive.

SYNERGIES

The merger is expected to generate annual cost savings of approximately $50
million. Savings are expected to come largely from the joint management of
Energy East and RGS Energy subsidiaries in areas such as procurement,
information systems, and other administrative and general areas.

No layoffs are planned as a result of the combination. Both companies have
on-going cost reduction programs and, historically, have used reduced hiring and
attrition to minimize any workforce effects.

remain a subsidiary of RGS Energy, and it is expected that NYSEG will be a
wholly owned subsidiary of RGS Energy. Wes von Schack will continue to serve as
