The accompanying proxy, to be mailed to Southern Union stockholders together
with the Notice of Special Meeting and this proxy statement on or about July
12, 2000, is solicited by Southern Union in connection with the special
meeting to be held on August 29, 2000.

                     QUESTIONS AND ANSWERS ABOUT THE MERGERS

Q:   WHAT WILL HAPPEN TO SOUTHERN UNION COMPANY AS A RESULT OF THE FALL RIVER
     GAS AND PROVENERGY MERGERS?

A:   If the Fall River Gas merger is completed, Fall River Gas will merge into
     Southern Union, Fall River Gas' utility operations will become a division
     of Southern Union, and Fall River Gas' non-regulated subsidiary will
     become a subsidiary of Southern Union.  If the ProvEnergy merger is
     completed, ProvEnergy and its utility subsidiaries will merge with and
     into Southern Union, ProvEnergy's utility operations will become
     divisions of Southern Union, and ProvEnergy's non-utility subsidiaries
     will become subsidiaries of Southern Union.

Q:   WHAT DO I NEED TO DO NOW?

A:   You should carefully read and consider the information contained in this
     document. You should complete and sign your proxy and return it in the
     enclosed envelope as soon as possible so that your shares may be
     represented at the special meeting. Failing to vote in person, or by proxy
     will have the same effect as a vote against the merger agreements.

Q:   WHAT IS THE REQUIRED SOUTHERN UNION STOCKHOLDER VOTE TO APPROVE AND ADOPT
     THE MERGER AGREEMENTS?

A:   The merger agreements must be approved and adopted by the holders of at
     least two-thirds of the outstanding shares of Southern Union common stock
     entitled to vote at the special meeting in order to minimize any delay of
     regulatory approval of the Fall River Gas merger and the North Attleboro
     Gas Company merger (which is a part of the ProvEnergy merger) by the
     Massachusetts utility regulatory authority, in accordance with
     Massachusetts law.  No stockholder vote is required under Southern
     Union's organizational documents or Delaware corporation law.

Q:   WHO IS ENTITLED TO VOTE?

A:   Stockholders as of the close of business on the record date, July 3, 2000,
     are entitled to vote at the special meeting.  Each share of Southern Union
     common stock is entitled to one vote.

Q:   HOW DO I VOTE?

A:   Sign and date each proxy card you receive and return it in the prepaid
     envelope.  If you do not mark any selections, your proxy card will be
     voted in favor of the proposal.  You have the right to revoke your proxy
     at any time before the special meeting by (1) notifying Southern Union's
     Corporate Secretary, (2) attending the special meeting and voting in
     person or (3) returning a later-dated proxy. If you return your signed
     proxy card, but do not indicate your voting preferences, the proxy will
     be voted FOR the proposal on your behalf.

     The Board of Directors is not aware of any matter other than the matters
     described above to be presented for action at the special meeting. If a
     proposal other than the one listed in the Notice is presented at the
     special meeting, your signed proxy card gives authority to George L.
     Lindemann and Peter H. Kelley to vote on such matters. They intend to vote
     in accordance with their best judgment.

     Proxies should NOT be sent by stockholders to Southern Union but to
     Fleet Bank, N.A. c/o EquiServe, L.P., Southern Union's Registrar and
     Transfer Agent, at 150 Royal Street, Canton, Massachusetts 02021.

Q:   IS MY VOTE CONFIDENTIAL?

A:   Yes. Proxy cards, ballots and voting tabulations that identify individual
     stockholders are confidential. Only the inspectors of election and certain
     employees associated with processing proxy cards and counting the vote
     have access to your card. Additionally, all comments directed to Southern
     Union's management (whether written on the proxy card or elsewhere) will
     remain confidential, unless you ask that your name be disclosed.

Q:   WHO WILL COUNT THE VOTE?

A:   Representatives of Southern Union and its legal counsel, Fleischman and
     Walsh, L.L.P., will tabulate the votes and act as inspectors of the
     election.


Q:   WHAT DOES IT MEAN IF I GET MORE THAN ONE PROXY CARD?


                                       1

<PAGE>


A:   It is an indication that your shares are registered differently and are in
     more than one account, including your accounts in Southern Union's Direct
     Stock Purchase Plan, the executive compensation plans, employee benefit
     plans and shares credited to your Savings Plan account held in custody by
     the trustee, Wilmington Trust. Sign and return all proxy cards to ensure
     that all your shares are voted.

Q:   WHAT CONSTITUTES A QUORUM?

A:   As of the record date, 49,509,738 shares of the Southern Union common
     stock were issued and outstanding. A majority of the outstanding shares,
     present or represented by proxy, constitutes a quorum for the transaction
     of adopting proposals at the special meeting. If you submit a properly
     executed proxy card, then you will be considered part of the quorum. If
     you are present or represented by a proxy at the special meeting and you
     abstain, your abstention will have the same effect as a vote AGAINST the
     proposal to approve the Fall River Gas and ProvEnergy merger agreements.
     Broker non-votes will be counted as part of the quorum but will not be
     part of the voting power present.

Q:   WHO CAN ATTEND THE SPECIAL MEETING?

A:   All stockholders as of the record date can attend.

Q:   WHEN ARE THE 2000 STOCKHOLDER PROPOSALS DUE?

A:   In order to be considered for inclusion in the next annual meeting's proxy
     statement, stockholder proposals must have been submitted in writing by
     June 30, 2000, to Dennis K. Morgan, Corporate Secretary, at Southern Union
     Company, 504 Lavaca Street, Eighth Floor, Austin, Texas 78701.

Q:   WHO PAYS FOR THIS PROXY SOLICITATION?

A:   Southern Union will reimburse brokerage houses and other custodians,
     nominees and fiduciaries for their reasonable out-of-pocket expenses for
     forwarding proxy and solicitation material to the owners of Southern Union
     common stock.

Q:   WHAT DO I NEED TO KNOW ABOUT THE FALL RIVER GAS AND PROVENERGY
     MERGERS?

A:   You should carefully read and consider the information contained in this
     document. You should complete and sign your proxy and return it in the
     enclosed envelope as soon as possible so that your shares may be
     represented at the special meeting. Failing to vote in person or by proxy
     will have the same effect as a vote AGAINST the mergers.

Q:   WHAT ARE THE REQUIRED FALL RIVER GAS AND PROVENERGY STOCKHOLDER VOTES TO
     APPROVE THE MERGERS?

A:   The Fall River Gas merger agreement must be approved by the holders of
     two-thirds of shares of Fall River Gas common stock entitled to vote at
     Fall River Gas' special meeting of stockholders to be held on August 29,
     2000, and the ProvEnergy merger agreement was approved by the holders of a
     majority of the shares of ProvEnergy common stock entitled to vote at
     ProvEnergy's special meeting held on May 22, 2000.

Q:   MUST EITHER OR BOTH MERGERS CLOSE, OR NEITHER CLOSE?

A:   We are planning to close the Fall River Gas Merger, the ProvEnergy merger
     and another pending merger with Valley Resources, Inc., all at essentially
     the same time, but it is possible that we might not. Each of the three
     mergers is separate. Any of the three mergers may close whether either (or
     both) of the other mergers close. Southern Union plans to close all three
     mergers at the same time, but they may close at different times.  There is
     no assurance that any or all three of the mergers will close.

Q:   WHEN ARE THE MERGERS EXPECTED TO BE COMPLETED?

A:   Southern Union is working as quickly as possible, along with its merger
     partners, and hopes to complete both mergers in September 2000.

Q:   AM I ENTITLED TO DISSENTERS' RIGHTS?

A:   Under Delaware law, you do not have dissenters' rights in connection with
     either the Fall River Gas merger or the ProvEnergy merger.

Q:   MY SHARES ARE HELD IN "STREET NAME." WILL MY BROKER VOTE MY SHARES ON THE
     MERGERS?

A:   A broker will vote your shares on the merger agreements only if you
     provide your broker with instructions on how to vote. You should follow
     the directions provided by your broker(s) regarding how to instruct
     brokers to vote the shares.


Q:   WHO CAN HELP ANSWER MY QUESTIONS?

                                  THE COMPANIES

SOUTHERN UNION (SEE PAGE 71)

Southern Union is a publicly owned international energy company headquartered
in Austin, Texas, that primarily engages in the distribution of natural gas
and is one of the fifteen largest distributors in the nation by customer
count. Southern Union serves more than 1.2 million customers through: its four
natural gas divisions in Texas, Missouri, Pennsylvania, and Florida; its
propane distribution subsidiaries; and its equity ownership in a natural gas
distribution company serving Piedras Negras, Mexico. Through its subsidiaries,
Southern Union also markets natural gas to end users, operates natural gas
pipeline systems, generates and markets electricity, and constructs, maintains
and rehabilitates natural gas distribution pipelines. Southern Union recently
completed a merger with Pennsylvania Enterprises, Inc. ("PEI"), on November 4,
1999 (see "Recent Developments"). On October 4, November 14 and November 30,
1999, Southern Union entered into merger agreements with Fall River Gas,
ProvEnergy and Valley Resources, Inc. ("Valley Resources"), respectively (see
"Recent Developments").

FALL RIVER GAS (SEE PAGE 72)

Fall River Gas is a publicly owned company, headquartered in Fall River,
Massachusetts, that is primarily engaged in the distribution of natural gas.
Fall River Gas provides natural gas to more than 48,000 customers in
southeastern Massachusetts. Through its non-regulated subsidiary, Fall River
Gas markets and rents water heaters, conversion burners and central heating
and air conditioning systems to customers in Fall River Gas' service area.

PROVENERGY (SEE PAGE 73)

ProvEnergy is a distributor and marketer of natural gas, heating oil and
petroleum products, as well as a marketer of electricity and energy services.
ProvEnergy serves approximately 181,000 gas utility customers in Rhode Island
and Massachusetts. Its principal subsidiaries within its regulated operations
include The Providence Gas Company ("Providence Gas") and North Attleboro Gas
Company ("North Attleboro Gas").

                       THE SOUTHERN UNION SPECIAL MEETING

PURPOSE, TIME AND PLACE

The Southern Union special meeting will be held at 2:00 p.m. (Central Time) on
August 29, 2000, in Southern Union's offices at Lavaca Plaza, 504 Lavaca
Street, Austin, Texas. At the special meeting, holders of Southern Union
common stock will be asked to approve and adopt the Fall River Gas and
ProvEnergy merger agreements.

RECORD DATE; VOTING POWER; VOTE REQUIRED (SEE PAGE 28)

If you owned shares of Southern Union common stock as of the close of business
on July 3, 2000, you are entitled to vote at the special meeting.

On that date, there were 49,509,738 shares of Southern Union common stock
outstanding. Holders of Southern Union common stock will have one vote at the
special meeting for each share of Southern Union common stock they own on that
date.

                                       7

<PAGE>

As of the close of business on June 30, 2000, directors and executive officers
of Southern Union and members of Chairman Lindemann's family beneficially
owned and were entitled to vote approximately 32% of the shares of Southern
Union outstanding on that date. Each of them has indicated his or her present
intention to vote, or cause to be voted, the Southern Union common stock owned
by him or her for the proposal to approve and adopt the merger agreements.

A majority of the shares of Southern Union common stock outstanding and
entitled to vote on the record date must be present in person or by proxy at
the special meeting or voted by telephone in order for a quorum to be present.

Consummation of the mergers requires the approval of the merger proposal by at
least two-thirds of the shares of Southern Union outstanding and entitled to
vote at the meeting in order to minimize any delay of regulatory approval of
the Fall River Gas merger and the North Attleboro merger (which is a part of
the ProvEnergy merger) by the Massachusetts utility regulatory authority, in
accordance with Massachusetts law. No stockholder vote is required under
Southern Union's organizational documents or Delaware corporation law.

SHARE OWNERSHIP OF MANAGEMENT; MANAGEMENT VOTE; VOTING AGREEMENT

As of the close of business on June 30, 2000, directors and executive officers
of Southern Union and members of Chairman Lindemann's family beneficially
owned and were entitled to vote shares of Southern Union common stock that
represented approximately 32% of the shares of Southern Union entitled to vote
on the merger agreements. Each of them has indicated his or her present
intention to vote, or cause to be voted, the Southern Union common stock owned
by him or her for the approval and adoption of the merger agreements. The
Lindemann family members have given an irrevocable proxy to ProvEnergy with
respect to voting their Southern Union common stock (representing
approximately 27% of shares entitled to vote) for the ProvEnergy merger
agreement and the transactions contemplated thereby. Directors and executive
officers (other than the Lindemanns, who have signed the proxy referred to
above) beneficially owned and were entitled to vote approximately 5% of the
shares of Southern Union common stock entitled to vote on the merger
agreements.

VOTING OF PROXIES

If you hold your shares of Southern Union common stock through a broker or
nominee, you must instruct your broker on how you would like to vote or these
shares will not be voted, although they may be counted as present if your
broker or nominee returns a proxy card without any voting instructions.
Similarly, a properly executed proxy marked "ABSTAIN" will be counted as
present, but will not be counted as a vote cast. ACCORDINGLY, ABSTENTIONS AND
BROKER NON-VOTES WILL HAVE THE EFFECT OF A VOTE "AGAINST" THE PROPOSAL FOR THE
APPROVAL AND ADOPTION OF THE MERGER AGREEMENTS.

                            THE FALL RIVER GAS MERGER

SUMMARY (SEE PAGE 42)

We are asking you to approve and adopt the merger agreement that provides for
the merger of Fall River Gas into Southern Union. Fall River Gas' utility
operations will become a division of Southern Union, and Fall River Gas'
non-regulated subsidiary will become a subsidiary of Southern Union.

The Fall River Gas merger will become effective following the Fall River Gas
approval of the merger agreement by the stockholders of Fall River Gas and the
satisfaction or waiver of all other conditions to the merger. At this time,
these conditions include certain approvals of the state regulatory commissions
of Massachusetts, Pennsylvania and Florida.

The merger agreement between Southern Union and Fall River Gas is attached at
the back of this proxy statement as Appendix A. We encourage you to read the
Fall River Gas merger agreement since it is the legal document that governs
the Fall River Gas merger.

FALL RIVER GAS MERGER CONSIDERATION (SEE PAGE 42)

When the Fall River Gas merger is completed, each share of Fall River Gas
common stock will be canceled. Fall River Gas stockholders will have the
option to elect either cash or Southern Union common stock or a combination of
both in exchange for their shares of Fall River Gas, subject to certain
limitations.

                                       8

<PAGE>

Each share of Fall River Gas common stock that a Fall River Gas stockholder
elects to exchange for cash will be converted into the right to receive $23.50
in cash unless too many Fall River Gas stockholders elect to receive cash. No
more than 50% of the aggregate consideration paid to all Fall River Gas
stockholders may consist of cash, including cash paid to Fall River Gas
stockholders in lieu of issuing them fractional shares of Southern Union
common stock. If the Fall River Gas stockholders' elections to receive cash
for their shares exceed this cash limitation, the amount of cash paid to each
Fall River Gas stockholder electing cash will be reduced proportionately.
Thus, if too many Fall River Gas stockholders elect to receive cash,
consequently exceeding the cash limitation, a combination of cash and Southern
Union common stock having a deemed value of $23.50 will be delivered to Fall
River Gas stockholders in exchange for each share they elected to be exchanged
for cash.

Each share of Fall River Gas common stock that Fall River Gas stockholders
elect to exchange for Southern Union common stock or do not elect to exchange
for cash (or cannot exchange for cash because too many Fall River Gas
stockholders have elected to exchange for cash as described above), will be
converted into the right to receive that number of whole shares of Southern
Union common stock having a value of $23.50. Southern Union will not issue any
fractional shares of its common stock in the merger. Instead, Fall River Gas
stockholders will get cash for any fractional shares of Southern Union common
stock they would otherwise receive.

Fall River Gas stockholders will be entitled to receive Southern Union common
stock in the merger if:

-    they elect to receive Southern Union common stock;

-    they elect to receive cash and the Fall River Gas stockholders
     exceed the cash limitation;

-    they do not indicate a preference as to the type of consideration
     they want to receive; or

-    they do not properly complete the form of election provided to them by the
     company Southern Union has selected to be the paying agent in connection
     with the merger.

The exact number of shares of Southern Union common stock a Fall River Gas
stockholder will receive for each share of Fall River Gas common stock that he
or she owns will depend on the average price of Southern Union common stock on
the New York Stock Exchange for the ten trading-day period beginning on the
twelfth trading day and ending on the third trading day before the closing of
the merger (counting from and including the trading day immediately before the
closing).

If the average price of Southern Union's common stock during this ten
trading-day period is:

-    Above $19.6875, the number of shares of Southern Union common stock will
     be fixed at 1.19365 for each share of Fall River Gas common stock.

-    Between $16.875 and $19.6875, the number of shares of Southern Union
     common stock will be adjusted so that each share of Fall River Gas' common
     stock will be exchanged for Southern Union common stock having a value
     equal to $23.50 divided by the average trading price during the period of
     time described above.

-    Below $16.875, but at least $15.00, the number of shares of Southern Union
     common stock will be fixed at 1.39259 for each share of Fall River Gas
     common stock.

-    Below $15.00, Fall River Gas has the option to terminate the merger
     agreement. If Fall River Gas does not terminate the merger agreement, each
     Fall River Gas stockholder will receive 1.39259 shares of Southern Union
     common stock per share of Fall River Gas common stock.

CERTAIN FEDERAL INCOME TAX CONSEQUENCES OF THE FALL RIVER GAS MERGER
(SEE PAGE 33)

Southern Union's stockholders will not exchange or otherwise dispose of any
Southern Union common stock in the Fall River Gas merger, so they will
recognize no taxable gain or loss. The Fall River Gas merger will not result
in the recognition of gain or loss to Southern Union or Fall River Gas.

                                       9

<PAGE>

INTERESTS OF FALL RIVER GAS OFFICERS AND DIRECTORS IN THE FALL RIVER GAS
MERGER (SEE PAGE 32)

Fall River Gas officers and the Fall River Gas board have interests in the
merger that may be different from, or in addition to, the interests of Fall
River Gas stockholders generally. These interests include employment
agreements. In addition, some Fall River Gas executives will become Southern
Union division executives after the merger.

The merger will constitute a "change in control" of Fall River Gas and this
will entitle certain Fall River Gas officers, in accordance with the terms of
their respective employment agreements, to receive lump sum severance benefits
if the officer is terminated without cause or terminates his or her own
employment within thirty-six months after the date the Fall River Gas merger
is completed. On October 4, 1999, these employment agreements were amended.
These amendments will become effective as of the date the Fall River Gas
merger is completed. These amendments provide for payment to Bradford J.
Faxon, Peter H. Thanas and John F. Fanning of $1,000,000, $700,000 and
$300,000, respectively. If Southern Union continues their employment with Fall
River Gas, these payments will be made in equal monthly installments over an
eighteen-month period beginning on the effective date of the merger. These
payments would be offset against any severance payments that may become owed
under any of these agreements.

For six years after the Fall River Gas merger, Southern Union has also agreed
to indemnify, and use its reasonable best efforts to provide liability
insurance for present and former officers and directors of Fall River Gas
against acts and omissions occurring before the merger under certain
circumstances.

REGULATORY APPROVALS FOR THE FALL RIVER GAS MERGER (SEE PAGE 34)

Certain approvals from the state regulatory commissions of Massachusetts,
Pennsylvania and Missouri, as well as the expiration or earlier termination of
the applicable waiting period under the Hart-Scott-Rodino Antitrust
Improvements Act of 1976 are required in order to complete the merger. On May
11, 2000, the Pennsylvania commission approved the Fall River Gas merger. On
June 28, 2000, the Missouri commission approved the Fall River Gas merger.
Authorization from the state regulatory commissions of Florida and
Pennsylvania for Southern Union to issue debt securities and/or common stock
sufficient to complete the Fall River Gas merger is also required. None of the
other required state approvals have been received as of the date of this proxy
statement. No Texas regulatory approvals are required in connection with the
merger.

Subsequent to the execution of the Fall River Gas merger agreement, the issue
arose as to whether Southern Union was required under Massachusetts law to
obtain the approval of the Fall River Gas transaction by holders of two-thirds
of the outstanding shares of Southern Union common stock in connection with
obtaining the approval of the Massachusetts Department of Telecommunications
and Energy of Southern Union's acquisition of Fall River Gas. In order to
eliminate any uncertainty concerning this issue and to facilitate the closing
of the transaction, Southern Union advised Fall River Gas and the
Massachusetts Department of Telecommunications and Energy that it intends to
seek, and through this proxy statement at the Southern Union special meeting
it is seeking, such stockholder approval.

Southern Union has advised Fall River Gas that George Lindemann, the Chairman
of the Board and Chief Executive Officer of Southern Union, and members of his
immediate family have advised Southern Union that they intend to vote all of
the shares of Southern Union common stock that they beneficially own and are
entitled to vote in favor of the approval of the Fall River Gas merger
agreement and the transactions contemplated thereby. As of June 30, 2000,
those Lindemann family members beneficially owned and were entitled to vote
approximately 27% of the shares of Southern Union common stock then
outstanding.

Southern Union has advised Fall River Gas that each of Southern Union's
directors and executive officers has advised Southern Union that they intend
to vote their shares of Southern Union common stock in favor of the approval
of the Fall River Gas merger agreement and the transactions contemplated
thereby. As of June 30, 2000, those directors and executive officers (other
than the Lindemanns), beneficially owned and were entitled to vote
approximately 5% of the shares of Southern Union common stock then
outstanding. Together, Southern Union's directors, executive officers and the
Lindemanns represent a total of approximately 32% of the shares of Southern
Union common stock outstanding as of June 30, 2000.

<PAGE>

CONDITIONS TO THE COMPLETION OF THE FALL RIVER GAS MERGER (SEE PAGE 49)

Completion of the Fall River Gas merger depends on the satisfaction of certain
conditions, including:

-    Obtaining the approval of two-thirds of the outstanding shares of Fall
     River Gas common stock.

-    All required governmental approvals obtained without material adverse
     conditions. To facilitate obtaining the approval of the transaction by the
     Massachusetts Department of Telecommunications and Energy, Southern Union
     is seeking the approval of the transaction by holders of two-thirds of the
     outstanding shares of Southern Union common stock.

-    No court or administrative order issued to prevent the Fall River Gas
     merger.

-    Effectiveness of the registration statement in which the Fall River Gas
     proxy statement is included.

-    Listing on the NYSE of the Southern Union common stock being issued to
     Fall River Gas stockholders in connection with the Fall River Gas merger.

-    The receipt of certain third-party consents and approvals.

AMENDMENT OF THE FALL RIVER GAS MERGER AGREEMENT (SEE PAGE 50)

Southern Union and Fall River Gas may amend in writing the terms of the Fall
River Gas merger agreement.

TERMINATION OF THE FALL RIVER GAS MERGER AGREEMENT AND TERMINATION FEES AND
EXPENSES (SEE PAGE 50 AND PAGE 51)

Fall River Gas and Southern Union may terminate the Fall River Gas merger
agreement by mutual written consent without completing the Fall River Gas
merger. The Fall River Gas merger agreement may be terminated by either Fall
River Gas or Southern Union in the following instances:

-    if less than two-thirds of the Fall River Gas stockholders vote to
     approve the merger;

-    if a court issues a non-appealable order that prohibits the
     consummation of the merger;

-    if the merger is not completed by October 15, 2000 (this date may be
     extended to February 28, 2001 to obtain certain governmental approvals);
     or

-    if the other party breaches a warranty, covenant, agreement or
     representation contained in the Fall River Gas merger agreement.

Fall River Gas may terminate the merger if the average trading price of
Southern Union common stock used to determine the number of shares of Southern
Union common stock to be received by Fall River Gas stockholders in the merger
is lower than $15.00.

Also, the merger agreement may be terminated by Fall River Gas if it signs an
agreement for a business combination with another party under certain
circumstances. Additionally, Southern Union may terminate the merger if: 1)
the Fall River Gas board or one of its committees withdraws or modifies its
approval or recommendation of approval of the merger agreement to the Fall
River Gas stockholders; or 2) if a third party or group acquires a majority of
Fall River Gas' shares. In any of these events, Fall River Gas may be required
to pay Southern Union a termination fee of $1.5 million.

ACCOUNTING TREATMENT FOR THE FALL RIVER GAS MERGER (SEE PAGE 34)

The Fall River Gas merger will be accounted for using the purchase method of
accounting in accordance with generally accepted accounting principles.

SUMMARY (SEE PAGE 52)

We are asking you to approve and adopt the merger agreement that provides for
the merger of ProvEnergy into Southern Union. Upon completion of the
transactions contemplated by the ProvEnergy merger agreement, ProvEnergy and
each of its two gas utility subsidiaries (Providence Gas, its Rhode Island
utility subsidiary and North Attleboro Gas, its Massachusetts utility
subsidiary) will be merged into Southern Union (together, the "ProvEnergy
merger") and its utility operations will operate as two divisions of Southern
Union with the Rhode Island operations in one division and the Massachusetts
operations in the other division. The ProvEnergy merger will become effective
following the approval of the ProvEnergy merger agreement by the shareholders
of ProvEnergy and the satisfaction or waiver of all other conditions to the
ProvEnergy merger agreement. On May 22, 2000, the shareholders of ProvEnergy
approved the ProvEnergy merger. At this time, conditions to be met include
certain approvals of the state regulatory commissions of Massachusetts and
Rhode Island with respect to certain of the mergers, and Pennsylvania and
Florida with respect to certain related financing matters. Regulatory
approvals required for the mergers have been received from the regulatory
commissions of Missouri and Pennsylvania.

The merger agreement between Southern Union and ProvEnergy is attached at the
back of this proxy statement as Appendix C. We encourage you to read the
ProvEnergy merger agreement since it is the legal document that governs the
ProvEnergy merger.

PROVENERGY MERGER CONSIDERATION (SEE PAGE 53)

When the merger of GUS (Southern Union's acquisition subsidiary) into
ProvEnergy is completed, each share of ProvEnergy common stock will be
cancelled and ProvEnergy shareholders will receive $42.50 in cash for each
share of ProvEnergy common stock they own.

CERTAIN FEDERAL INCOME TAX CONSEQUENCES OF THE PROVENERGY MERGER (SEE PAGE 39)

Southern Union's stockholders will not exchange or otherwise dispose of any
Southern Union common stock in the ProvEnergy merger, so they will recognize
no taxable gain or loss. The ProvEnergy merger will not result in the
recognition of gain or loss to Southern Union or ProvEnergy.

INTERESTS OF PROVENERGY OFFICERS AND DIRECTORS IN THE PROVENERGY MERGER (SEE
PAGE 38)

Some ProvEnergy directors, officers and executives have interests in the
ProvEnergy merger that may be different from, or in addition to, the interests
of ProvEnergy shareholders generally. These interests include employment
agreements and stock options. In addition, some ProvEnergy executives will
become Southern Union directors or executives after the ProvEnergy merger.
These interests include:

-    the Chief Executive Officer of ProvEnergy will be elected to the
     board of directors of Southern Union,

                                     12

<PAGE>

-    Mr. James H. Dodge will serve as Chief Executive Officer and
     President, and Mr. James DeMetro will serve as Executive Vice
     President, Energy Services, of the ProvEnergy and North Attleboro
     divisions of Southern Union and all other energy-related businesses
     of Southern Union conducted in New England,

-    each performance share issuable to employees under a ProvEnergy incentive
     plan will be fully earned and converted into a right to receive $42.50 in
     cash,

-    all stock options will be deemed fully vested and will be converted into a
     right to receive a cash payment, and

-    Mr. James H. Dodge and Mr. James DeMetro will receive enhanced
     compensation and other benefits.

For six years after the ProvEnergy merger, Southern Union has agreed to
indemnify and to use its reasonable best efforts to provide liability
insurance for present and former officers and directors of ProvEnergy against
acts and omissions occurring before the merger under certain circumstances.

REGULATORY APPROVALS FOR THE PROVENERGY MERGER (SEE PAGE 39)

Certain approvals from the state regulatory commissions of Massachusetts,
Rhode Island, Pennsylvania, Missouri and Florida, and from the Federal Energy
Regulatory Commission, and the expiration or earlier termination of the
applicable waiting period under the Hart-Scott-Rodino Antitrust Improvements
Act of 1976, are required to complete the ProvEnergy merger. As of the date of
this proxy statement, the Pennsylvania and Missouri commissions' approval of
the ProvEnergy merger are the only required regulatory approvals for the
ProvEnergy merger that have been obtained.

Subsequent to the execution of the ProvEnergy merger agreement, the issue
arose as to whether Southern Union was required under Massachusetts law to
obtain the approval of the ProvEnergy transaction by holders of two-thirds of
the outstanding shares of Southern Union common stock in connection with
obtaining the approval by the Massachusetts Department of Telecommunications
and Energy of Southern Union's acquisition of North Attleboro Gas,
ProvEnergy's Massachusetts utility subsidiary. In order to eliminate any
uncertainty concerning this issue and to facilitate the closing of the
transaction, Southern Union advised ProvEnergy and the Massachusetts
Department of Telecommunications and Energy that it intends to seek, and
through this proxy statement at the Southern Union special meeting it is
seeking, such stockholder approval.

ProvEnergy has received a commitment and an irrevocable proxy from George
Lindemann, the Chairman of the Board and Chief Executive Officer of Southern
Union, and members of his immediate family to vote all of the shares of
Southern Union common stock that they beneficially own and are entitled to
vote in favor of the approval of the ProvEnergy merger agreement and the
transactions contemplated thereby. As of June 30, 2000, those Lindemann family
members beneficially owned and were entitled to vote approximately 27% of the
shares of Southern Union common stock then outstanding.

Southern Union has advised ProvEnergy that each of Southern Union's directors
and executive officers has advised Southern Union that they intend to vote the
shares of Southern Union common stock that they beneficially own and are
entitled to vote in favor of the approval of the ProvEnergy merger agreement
and the transactions contemplated thereby. As of June 30, 2000, those
directors and executive officers (other than the Lindemanns, who have signed
the proxy referred to above) beneficially owned and were entitled to vote
approximately 5% of the shares of Southern Union common stock then
outstanding. Together with the Lindemanns' proxy, this represents a total of
approximately 32% of the shares of Southern Union common stock outstanding as
of June 30, 2000.

CONDITIONS TO THE PROVENERGY MERGER (SEE PAGE 59)

Completion of the ProvEnergy merger depends on the satisfaction of certain
conditions, including the following:

-    Obtaining required governmental approvals by final order in such form as
     are not, and with no conditions that are, individually or in the
     aggregate, reasonably likely to have a ProvEnergy material adverse effect
     or a material adverse effect on the business, financial condition or
     results of operations of Southern Union, or which would otherwise, in
     Southern Union's reasonable determination, be unduly burdensome to
     Southern Union in a manner that would, individually or in the aggregate,
     be reasonably likely to have a ProvEnergy material adverse effect or a
     material adverse effect on the business, financial condition or results
     of operations of Southern Union. To facilitate obtaining the approval of
     the transaction by the Massachusetts Department of Telecommunications and
     Energy, Southern Union is

                                     13

<PAGE>

     seeking the approval of the transaction by holders of two-thirds of the
     outstanding shares of Southern Union common stock.

-    Obtaining the approval of holders of a majority of the outstanding shares
     of ProvEnergy common stock, which was obtained on May 22, 2000.

-    Obtaining the consent of holders of at least 80% in aggregate principal
     amount of all First Mortgage Bonds of Providence Gas outstanding to each
     of the amendments to the Providence Gas Indenture set forth on Schedule
     6.1(n) to the ProvEnergy merger agreement.

-    The redemption of all of the outstanding shares of Providence Gas
     preferred stock, which was completed on March 1, 2000.

-    The receipt of certain third party consents and approvals.

AMENDMENT OF THE PROVENERGY MERGER AGREEMENT (SEE PAGE 60)

Southern Union and ProvEnergy may amend in writing the terms of the ProvEnergy
merger agreement.

TERMINATION OF THE PROVENERGY MERGER AGREEMENT AND TERMINATION FEES
AND EXPENSES (SEE PAGE 60 AND PAGE 61)

The ProvEnergy merger agreement can be terminated at any time prior to the
closing:

-    by mutual written consent of ProvEnergy and Southern Union,

-    by either ProvEnergy or Southern Union if there is a non-appealable court
     order prohibiting the consummation of the ProvEnergy merger,

-    by either ProvEnergy or Southern Union if there is a breach by the other
     party of any representation or warranty, which breach cannot be cured,
     except for inaccuracies which would not be reasonably likely to result in
     a material adverse effect,

-    by ProvEnergy as a result of a superior proposal, provided ProvEnergy has
     paid the termination fee,

-    by either ProvEnergy or Southern Union if the approval of ProvEnergy
     shareholders is not obtained (which approval was obtained on May 22,
     2000),

-    by Southern Union if the board of directors of ProvEnergy withdraws or
     modifies the approval or recommendation of the board in favor of the
     merger, approves or recommends (or proposes to do so) certain business
     combinations, causes ProvEnergy to enter into a definitive agreement with
     respect to certain business combinations, resolves to do any of the
     foregoing or fails to redeem all of the outstanding shares of Providence
     Gas preferred stock (which redemption was completed on March 1, 2000),

-    by Southern Union if a third party or group acquires more than 50% of the
     voting power of the outstanding voting securities of ProvEnergy, or

-    by either ProvEnergy or Southern Union if the closing has not occurred by
     November 15, 2000; provided, that if all conditions to closing have been
     fulfilled except for approvals by any governmental body, then the
     termination date will be extended until April 1, 2001.

ProvEnergy is required to pay Southern Union a $7.5 million termination fee in
cash if the ProvEnergy merger agreement is terminated under specified
circumstances after a third party makes a proposal to acquire ProvEnergy or if
a third party or group acquires more than 50% of the voting power of the
outstanding voting securities of ProvEnergy.

ACCOUNTING TREATMENT FOR THE PROVENERGY MERGER (SEE PAGE 40)

The ProvEnergy merger will be accounted for using the purchase method of
accounting in accordance with generally accepted accounting principles.

                            MERGER-RELATED FINANCING

Southern Union's management is evaluating various sources and methods of
financing the amount necessary to finance the cash portion of the
consideration to be paid to Fall River Gas stockholders, the all cash
consideration to be paid to ProvEnergy shareholders, the all cash
consideration to be paid to Valley Resources stockholders, and all related
costs and refinancings anticipated in connection with these mergers. Southern
Union could require new financing of up to approximately $600 million to
complete the three pending mergers, if Fall River Gas stockholders choose to
receive the maximum of 50% of the aggregate merger consideration that may be
paid to Fall River Gas stockholders in cash and if all of the approximately
$140 million of existing long-term debt of all three companies being acquired
must be refinanced rather than amended and assumed as planned. Presently,
Southern Union anticipates funding these requirements with bank borrowings;
however, it does not yet have commitments (see page 41).

                          NO STATUTORY APPRAISAL RIGHTS

Holders of Southern Union common stock who do not vote in favor of the
proposal to approve the Fall River Gas and ProvEnergy mergers will not be
entitled to appraisal rights (see page 41).

              RECOMMENDATION TO SOUTHERN UNION COMMON STOCKHOLDERS

The Southern Union board of directors believes that the Fall River Gas and
ProvEnergy mergers are in the best interest of Southern Union stockholders and
recommends that holders of Southern Union common stock vote "FOR" the proposal
to approve and adopt the Fall River Gas and ProvEnergy merger agreements. The
reasons for the board's recommendation are set forth on page 31 for Fall River
Gas and page 37 for ProvEnergy.

SELECTED UNAUDITED PRO FORMA COMBINED CONDENSED FINANCIAL DATA

The following selected unaudited pro forma combined condensed financial data
presents the combined financial data of Southern Union, Fall River Gas, PEI,
ProvEnergy and Valley Resources including their respective subsidiaries, after
giving effect to Southern Union's merger with each of them. The PEI merger,
completed on November 4, 1999, was, and the Fall River Gas, ProvEnergy and
Valley Resources mergers will be, accounted for as a purchase. The unaudited
pro forma combined condensed financial data also give effect to Southern
Union's issuance of $300 million of senior notes that was completed on
November 3, 1999, in anticipation of the PEI merger, prospective financing for
the pending acquisitions by merger of Fall River Gas, ProvEnergy and Valley
Resources, and the assumpton of certain debt of the acquired companies. All of
these transactions are assumed to be effective for the period indicated in the
following selected unaudited pro forma combined condensed financial data (see
"Recent Developments").

(a)  Southern Union incurred pre-tax costs associated with various acquisition
     efforts unrelated to the Fall River Gas, PEI, ProvEnergy and Valley
     Resources mergers, and litigation costs associated with an unsuccessful
     acquisition, of $3,839,000 and $6,664,000 for the year ended June 30, 1999
     and the nine-months ended March 31, 2000, respectively.
(b)  Funding for the Fall River Gas, ProvEnergy and Valley Resources mergers is
     assumed to be provided by bank borrowings at an estimated annual interest
     rate of 7.60%. This rate is what Southern Union believes would be obtained
     based on current market rates. These proceeds are assumed to be utilized:
     to finance the cash portion of the Fall River Gas, ProvEnergy and Valley
     Resources mergers and the settlement of any respective stock options; and
     to pay a total of approximately $9 million of various professional fees
     and change of control agreements expected to be incurred in connection
     with the three pending acquisitions. Additionally, long-term debt of $300
     million at an annual interest rate of 8.25% was issued on November 3, 1999
     in connection with the PEI merger.
(c)  In anticipation of the pending and completed acquisitions, the
     outstanding PEI and ProvEnergy preferred stock was repurchased prior to
     closing of the related merger.
(d)  Earnings (loss) per share for both periods presented were computed based
     on the weighted average number of shares of common stock outstanding
     during the period adjusted for the Southern Union 5% stock dividends
     distributed on June 30, 2000, August 6, 1999 and December 9, 1998, and the
     50% stock dividend distributed on July 13, 1998.
(e)  The March 31, 2000 information reflects an estimated issuance of Southern
     Union common stock to Fall River Gas stockholder s at an exchange ratio of
     1.39259 based on an average trading price of $15.7954 for Southern Union
     common stock at the average closing price per share for the ten trading
     day period ending on the third trading day before June 30, 2000, and
     assuming that half the Fall River Gas shares are not exchanged but paid
     for in cash.
(f)  Represents historical short-term debt and capital lease obligation of
     Southern Union, Fall River Gas, ProvEnergy and Valley Resources.

                 FORWARD-LOOKING STATEMENTS MAY PROVE INACCURATE

Southern Union has made forward-looking statements in this document (and in
documents that we have incorporated by reference) that are subject to risks
and uncertainties. Forward-looking statements include the information
concerning possible or assumed future results of operations of Southern Union,
Fall River Gas, ProvEnergy and Valley Resources. Also, when we use words such
as "believes," "expects," "anticipates," "intends," or similar expressions, we
are making forward-looking statements. You should note that many factors, some
of which are discussed elsewhere in this document and in the documents that we
incorporate by reference, could affect the future financial results of
Southern Union, Fall River Gas, ProvEnergy and Valley Resources and could
cause those results to differ materially from those expressed in our
forward-looking statements contained or incorporated by reference in this
document. The factors that could cause actual results to differ materially
from those indicated by such forward-looking statements include the following:

-    general economic, financial and business conditions;

-    effectiveness of hedging strategies;

-    competition in the energy services sector;

-    the availability of natural gas and oil;

-    development and operating costs;

-    the success and costs of advertising and promotional efforts;

-    the availability and terms of capital;

-    unanticipated environmental liabilities;

-    the impacts of unusual items resulting from ongoing evaluations of
     business strategies and asset valuations;

-    changes in business strategy;

-    the timing and extent of changes in commodity prices;

-    gas sales volumes;

-    weather conditions and other natural phenomena in our service
     territories;

-    the purchase and implementation of new technologies for enhancing
     customer service and/or operating efficiencies;

-    impact of relations with labor unions of bargaining-unit employees;

-    the receipt of timely and adequate rate relief;

-    the outcome of pending and future litigation;

-    governmental regulations and proceedings affecting the companies,
     including the restructuring of the natural gas industry in Massachusetts,
     Rhode Island, Texas, Missouri, Pennsylvania, and Florida;

-    the nature and impact of any extraordinary transaction such as any
     acquisition or divestiture of a business unit or any assets;

-    the risk that the businesses of PEI, Fall River Gas, ProvEnergy, Valley
     Resources and any other businesses or investments that Southern Union has
     acquired or may acquire may not be successfully integrated with the
     businesses of Southern Union.

                                      20

<PAGE>

This list provides only an example of some of the risks, uncertainties and
assumptions that may affect forward-looking statements. If any of these risks
or uncertainties materialize or fail to materialize, as applicable, or if the
underlying assumptions prove incorrect, actual results may differ materially
from those projected in the forward-looking statements.

The nature and impact of any extraordinary transactions such as any
acquisition or divestiture of a business unit or any assets may also cause
actual results to differ materially from estimates or projections contained in
forward-looking statements. Southern Union's strategic plan is to increase the
scale of its operations and the size of its customer base by pursuing and
completing future business combination transactions. Acquisitions may require
substantial additional financial expenditures that will need to be financed
through cash flow from operations or future debt and equity offerings. The
availability and terms of any such financing sources will depend upon various
factors and conditions such as Southern Union's cash flow and earnings, its
resulting capital structure, credit ratings and conditions in financial
capital markets at the time of any such offering. Any future acquisitions and
related financing arrangements or debt assumptions would likely increase its
aggregate indebtedness, and may increase the portion of its total
capitalization represented by debt. Acquisitions and financings will also
affect Southern Union's results due to factors such as its ability to realize
any anticipated benefits from such transactions, successful integration of new
and different operations and businesses, effects of different regional
economic and weather conditions, and the extent of any related debt financing.

Other factors that could cause actual results to differ materially from
estimates and projections contained in forward-looking statements are
described in the documents that have been incorporated by reference into this
document. You should not place undue reliance on forward-looking statements,
which speak only as of the date of this proxy statement, or, in the case of
documents incorporated by reference, the dates of those documents.

                               RECENT DEVELOPMENTS

In addition to the Fall River Gas and ProvEnergy mergers, Southern Union
recently has completed or agreed to the significant acquisitions described
below.

MERGER WITH PENNSYLVANIA ENTERPRISES, INC. Effective November 4, 1999, Southern
Union acquired PEI and its subsidiaries for approximately 17 million shares of
Southern Union common stock and approximately $36 million in cash plus the
assumption of approximately $150 million in debt. PEI's natural gas utility
businesses are being operated as the PG Energy and Honesdale Gas divisions of
Southern Union, which provide service to approximately 154,000 natural gas
customers in northeastern and central Pennsylvania (including the cities of
Wilkes-Barre, Scranton and Williamsport). Through PG Energy Services, Inc., a
PEI subsidiary that Southern Union acquired in the PEI merger, Southern Union
markets electricity and other products and services under the name PG Energy
Power Plus, principally in northeastern and central Pennsylvania. Other
subsidiaries that Southern Union acquired in the PEI merger include PEI Power
Corporation, Keystone Pipeline Services, Inc. (itself a wholly owned subsidiary
of PG Energy Services, Inc.) and Theta Land Corporation. PEI Power Corporation,
an exempt wholesale generator (within the meaning of the Public Utility Holding
Company Act of 1935), generates and sells electricity. Keystone Pipeline
Services, Inc. is engaged primarily in the construction, maintenance and
rehabilitation of natural gas distribution pipelines. Theta Land Corporation
engages in the sale of property for residential and commercial development and
was sold for $12.1 million in January 2000.

MERGER WITH VALLEY RESOURCES, INC. On November 30, 1999, Southern Union, SUG
Acquisition Corporation a Rhode Island corporation and wholly-owned subsidiary
of Southern Union, and Valley Resources (AMEX: "VR") entered into a definitive
merger agreement. The agreement calls for Valley Resources to merge into
Southern Union in a transaction valued at approximately $160 million, including
the assumption of debt. Valley Resources shareholders will receive $25.00 in
cash for each of the approximately 4.98 million shares of Valley Resources
common stock outstanding. Valley Resources, headquartered in Cumberland, Rhode
Island, provides natural gas utility service to more than 64,000 customers
through its subsidiaries, Valley Gas Company and Bristol & Warren Gas Company.
Valley Gas Company's service area covers a 92 square mile area in the Blackstone
Valley Region located in the northeastern portion of Rhode Island that has a
population of approximately 250,000. Bristol & Warren Gas Company's service area
covers approximately 15 square miles in the eastern portion of Rhode Island that
has a population of approximately 35,000. Other Valley Resources subsidiaries
rent and sell gas appliances, sell liquid propane in Rhode Island and nearby
Massachusetts, and distribute as a wholesaler franchised lines to plumbing and
heating contractors. Valley Resources also has a 90% interest in Alternate
Energy Corporation, which sells, installs and designs natural gas conversion
systems and facilities, is an authorized representative of the ONSI fuel cell,
holds patents for a natural gas/diesel co-firing system and for a device to
control the flow of fuel on dual-fuel equipment. Valley Resources shareholders
approved the Valley Resources merger at their special meeting on June 13, 2000.
Southern Union anticipates completing the Valley Resources merger in September
2000 once all remaining conditions are satisfied, including receipt of all
regulatory approvals for the Valley Resources merger.

                       THE SOUTHERN UNION SPECIAL MEETING

PURPOSE, TIME AND PLACE

The special meeting will be held in Southern Union's offices at Lavaca Plaza,
504 Lavaca Street, Austin, Texas on August 29, 2000, at 2:00 p.m. (Central
Time), for the following purposes:

     (1)  To approve and adopt the Fall River Gas and ProvEnergy merger
          agreements;

     (2)  To transact such other business as may properly come before the
          meeting or any adjournment thereof.

RECORD DATE; VOTING POWER; VOTE REQUIRED

The Southern Union board has fixed the close of business on July 3, 2000 as the
record date for the determination of holders of Southern Union common stock
entitled to notice of and to vote at the special meeting. Southern Union common
stock, of which there were 49,509,738 shares outstanding and entitled to vote on
July 3, 2000, is the only class of securities of Southern Union entitled to vote
at the special meeting. A majority of the shares of Southern Union common stock
issued and outstanding and entitled to vote on the record date must be present
in person or by proxy at the special meeting or voted by telephone in order for
a quorum to be present for purposes of transacting business at the special
meeting.

In the event that a quorum is not present at the special meeting, it is expected
that the meeting will be adjourned or postponed to solicit additional proxies.
Holders of Southern Union common stock as of the record date are each entitled
to one vote per share on the approval and adoption of the merger agreement at
the special meeting. The approval and adoption requires the affirmative vote of
at least two-thirds of the shares of Southern Union common stock outstanding on
the record date. The Southern Union board recommends that Southern Union
stockholders vote "FOR" the proposal to approve and adopt the Fall River Gas and
ProvEnergy merger agreements.

SHARE OWNERSHIP OF MANAGEMENT; MANAGEMENT VOTE; VOTING AGREEMENTS

ProvEnergy has received commitments and irrevocable proxies from George
Lindemann, the Chairman of the Board and Chief Executive Officer of Southern
Union, and members of his immediate family to vote all of the shares of Southern
Union common stock that they beneficially own and are entitled to vote in favor
of the approval of the ProvEnergy merger agreement and the transactions
contemplated thereby. Southern Union has advised Fall River Gas that George
Lindemann, the Chairman of the Board and Chief Executive Officer of Southern
Union, and members of his immediate family have advised Southern Union that they
intend to vote all of the shares of Southern Union common stock that they
beneficially own and are entitled to vote in favor of the approval of the Fall
River Gas merger agreement and the transactions contemplated thereby. As of June
30, 2000, those Lindemann family members beneficially owned and were entitled to
vote approximately 27% of the shares of Southern Union common stock then
outstanding. See "Principal Stockholders -- Beneficial Owners of More Than 5% of
Southern Union's Outstanding Common Stock" for more information.

As of the close of business on June 30, 2000, directors and executive officers
of Southern Union (other than members of the Lindemann family) beneficially
owned and were entitled to vote shares of Southern Union common stock, which
represented approximately 5% of the shares of Southern Union common stock
outstanding on that date. Each of them has indicated his or her present
intention to vote, or cause to be voted, the Southern Union common stock owned
by him or her "FOR" the proposal to approve and adopt the merger agreements at
the special meeting. Together with the Lindemanns' proxy, this represents
approximately 32% of the shares outstanding as of June 30, 2000. See "Principal
Stockholders -- Southern Union Management Ownership" for additional information.

VOTING OF PROXIES

All holders of Southern Union common stock who are entitled to vote and are
represented at the special meeting by properly executed proxies received prior
to or at such meeting and not duly and timely revoked will have their shares
voted at the meeting in accordance with the instructions indicated on the
proxies. If no instructions are indicated, the proxies will be voted "FOR" the
proposal to approve and adopt the Fall River Gas and ProvEnergy merger
agreements.

<PAGE>

If any other matters are properly presented at the special meeting for
consideration, the persons named in the enclosed form of proxy, and acting
thereunder, will have discretion to vote on such matters in accordance with
their best judgment (unless authorization to use such discretion is withheld).
Southern Union is not aware of any matters expected to be presented at the
special meeting other than as described in the Notice of Special Meeting.

REVOCABILITY OF PROXIES

Delaware law provides that a proxy, unless coupled with an interest (for
example, a vote pooling or similar arrangement among holders of Southern Union
common stock, or between Southern Union and holders of Southern Union common
stock, or an unrevoked proxy in favor of an existing or potential creditor of a
holder of Southern Union common stock), is revocable at will by a holder of
Southern Union common stock, notwithstanding any other agreement or provision in
the proxy to the contrary. A holder of Southern Union common stock may revoke a
proxy by giving written notice of revocation to the clerk of Southern Union at
Southern Union's address set forth on page 6 of this proxy statement at any time
before the proxy is voted. Such revocation will be effective upon receipt of the
written notice by the Corporate Secretary of Southern Union.

SOLICITATION OF PROXIES

Southern Union will bear the costs of this solicitation of proxies. In addition
to solicitation by mail, arrangements may be made with brokerage houses and
other custodians, nominees and fiduciaries to send material to their principals,
and Southern Union may reimburse them for their expenses in so doing. To the
extent necessary in order to ensure a sufficient presence of holders of Southern
Union common stock to constitute a quorum, officers and other employees of
Southern Union or designated agents may, without additional remuneration, in
person or by telephone or telegram, request the return of proxies. In addition,
Southern Union has retained InnisFree M&A Incorporated ("InnisFree") for
assistance in the solicitation of proxies. For its services, InnisFree will
receive a fee estimated at $10,000 plus reimbursement for reasonable and
customary out-of-pocket expenses.

                            THE FALL RIVER GAS MERGER

THIS SECTION OF THE PROXY STATEMENT, AS WELL AS THE SECTION ENTITLED "THE FALL
RIVER GAS MERGER AGREEMENT," DESCRIBES CERTAIN ASPECTS OF THE PROPOSED MERGER
WITH FALL RIVER GAS. THESE SECTIONS HIGHLIGHT KEY INFORMATION ABOUT THE MERGER
AND THE MERGER AGREEMENT, BUT THEY MAY NOT INCLUDE ALL THE INFORMATION THAT YOU
WOULD LIKE TO KNOW. THE MERGER AGREEMENT BETWEEN FALL RIVER GAS AND SOUTHERN
UNION IS ATTACHED AS APPENDIX A TO THIS PROXY STATEMENT. WE URGE YOU TO READ THE
MERGER AGREEMENT IN ITS ENTIRETY.

SOUTHERN UNION BACKGROUND OF THE FALL RIVER GAS MERGER

For the past several years, Southern Union has pursued acquisition and business
combination opportunities. After the announcement of its merger agreement with
PEI, Southern Union management sought additional opportunities in the
northeastern United States to expand its presence in that region.

On June 21, 1999, Bradford J. Faxon, Chairman of the Board, Chief Executive
Officer and President, Peter H. Thanas Senior Vice President, and Thomas K.
Barry, director of Fall River Gas, met with Thomas F. Karam, President and Chief
Executive Officer of PEI, a Pennsylvania based gas utility holding company that
was then in the initial stages of its merger with Southern Union, and discussed,
in general terms, their respective companies and whether it would be appropriate
to initiate further discussions between representatives of Southern Union and
Fall River Gas regarding a possible business combination. As a follow-up to this
conversation, Mr. Karam sent Mr. Faxon copies of recent Southern Union public
reports.

On July 19, 1999, following several general conversations between Mr. Faxon and
Mr. Karam about the energy industry and the philosophies of their companies, and
the possibility of a strategic relationship between Southern Union and Fall
River Gas, Mr. Karam conveyed Southern Union's proposal to acquire Fall River
Gas, in an all stock transaction, valuing the Fall River Gas stock at $21 per
share. Mr. Faxon communicated the proposal to the executive committee of the
board of directors of Fall River Gas at the executive committee's July 23, 1999
meeting (director Ronald J. Ferris was also in attendance). The committee
concluded that the proposal was too low and instructed Mr. Faxon to seek a
higher proposed price. After Fall River Gas advised Southern Union of this
decision, additional discussions occurred between Mr. Faxon, Mr. Thanas, and Mr.
Karam and Peter H. Kelley, President and Chief Operating Officer of Southern
Union. On July 29, 1999 Southern Union made a revised proposal of $23.50 per
share and Mr. Faxon undertook to seek approval by the Fall River Gas board of
directors. Subsequently, discussions ensued between Messrs. Faxon, Thanas,
counsel for the respective companies and Mr. Karam as well as other
representatives of Southern Union with respect to other proposed terms for a
transaction.

On August 24, 1999, the Southern Union board unanimously approved an all stock
merger agreement with Fall River Gas.

On the morning of September 8, 1999, the board of Fall River Gas met to
consider a merger agreement with Southern Union. At the same time,at Fall
River Gas' request, the American Stock Exchange agreed to suspend trading in
the stock of Fall River Gas while the board and its advisors discussed the
merger. At this meeting, Mr. Kelley, Ronald J. Endres, Southern Union's
Executive Vice President and Chief Financial Officer, and Mr. Karam, made a
presentation describing Southern Union, its operations and recent corporate
history, including its 1994 Missouri acquisition and its then pending merger
with PEI, as well as its corporate plan of growth through acquisitions. Mr.
Endres discussed Southern Union's returns to investors and discussed Southern
Union's business vision of enhancing profitability through technological
advances. Mr. Karam summarized the benefits of Southern Union's strategies
and certain benefits of the proposed merger: (1) geographical diversification
and minimum employee disruption; (2) reduction in costs; (3) creation of
additional value through increased size; and (4) establishment of a New
England presence for Southern Union.

After this meeting, Fall River Gas issued a press release stating that it had
received an offer from an undisclosed party for an all stock transaction at
$23.50 per share, and that the board of directors had formed a committee to
help it evaluate the offer. During the next several days, additional
discussions were held among the representatives of Fall River Gas and
Southern Union, while the special committee gathered additional information
regarding Southern Union.

On the morning of September 17, 1999, the Fall River Gas board again met to
consider the proposed merger. After extensive discussion, the board
determined that it lacked sufficient consensus to recommend the merger as
structured. Fall River Gas then issued a press release stating that the board
had rejected the offer.


                                       30
<PAGE>

On September 27, 1999, the Executive Committee of Southern Union's board
approved a revised offer in order to provide that part of the consideration
Fall River Gas stockholders would receive in connection with the merger could
be cash rather than stock of Southern Union having determined that this
change was in the best interest of Southern Union and its stockholders,
customers and employees.

Following additional conversations between representatives of Southern Union
and Fall River Gas, by letter dated September 28, 1999, Mr. Karam conveyed
Southern Union's willingness to change the structure for its proposed merger
to provide that up to one-half of the consideration could be cash rather than
stock of Southern Union. At its regular meeting on September 30, 1999, Fall
River Gas' board considered the terms of Southern Union's revised offer. Fall
River Gas' counsel discussed various aspects of the merger agreement,
conditions to closing, as well as a likely time schedule. Following the
meeting, Messrs. Faxon and Thanas called representatives of Southern Union to
communicate the board's approval. After the close of business on October 4,
1999, the merger agreement was executed and the merger was publicly announced.

Subsequent to the execution of the merger agreement, the issue arose as to
whether Southern Union was required under Massachusetts law to obtain the
approval of the Fall River Gas merger by holders of two-thirds of the
outstanding shares of Southern Union common stock in connection with
obtaining the approval by the Massachusetts Department of Telecommunications
and Energy. In order to eliminate any uncertainty concerning this issue and
to facilitate the closing of the transaction, Southern Union advised Fall
River Gas and the Massachusetts Department of Telecommunications and Energy
that it would seek, and through this proxy statement at the Southern Union
special meeting it is seeking, such stockholder approval.

SOUTHERN UNION'S REASONS FOR THE FALL RIVER GAS MERGER

In reaching its determination that a merger with Fall River Gas is in the
best interest of Southern Union, and its stockholders, customers and
employees, the Southern Union board of directors, including its Executive
Committee, consulted with and relied upon information and reports prepared or
presented by Southern Union's management and Southern Union's legal advisors.
The following are the material factors considered by the Southern Union
board, including its Executive Committee, in pursuing acquisition
opportunities, generally, which are relevant to their approval of the merger
agreement with Fall River Gas, some of which contained both positive and
negative elements:

-    the terms of a proposed form of merger agreement consistent with those
     terms described under "The Fall River Gas Merger Agreement";

-    the likelihood of receipt of timely and satisfactory regulatory
     approvals for the merger;

-    the risk that the merger would not be consummated;

-    other recent and potential mergers involving utilities in the northeastern
     region of the country, particularly PEI, ProvEnergy and Valley Resources;

-    the substantial management time and effort that will be required to
     consummate all aspects of the recent and prospective mergers, including to
     integrate the operations of those companies, and the risks inherent in such
     integration;

-    other matters described under  "Forward-Looking Statements May
     Prove Inaccurate"; and

-    the results of Southern Union's business investigation of Fall
     River Gas and its subsidiary.

The foregoing discussion of the information and factors considered by the
Southern Union board, including its Executive Committee, is not intended to be
all-inclusive. In view of the wide variety of factors considered in connection
with its evaluation of acquisition opportunities, including this proposed
merger, the Southern Union board, including its Executive Committee, did not
find it practicable to, and did not, quantify or otherwise attempt to assign
relative weights to the foregoing factors. Rather, the Southern Union board,
including its Executive Committee, based its decisions on the totality of the
information presented to and considered by it.



                                       31

RECOMMENDATION OF SOUTHERN UNION'S BOARD OF DIRECTORS

On May 31, 2000 the Southern Union Board of Directors approved a resolution
recommending that the stockholders of Southern Union approve the Fall River
Gas Company merger at a special meeting of stockholders, due to the merger
being in the best interests of Southern Union, its stockholders, employees
and customers, and the desire to avoid unnecessary delay in the receipt of
certain regulatory approvals as previously explained.

INTERESTS OF FALL RIVER GAS OFFICERS AND DIRECTORS IN THE FALL RIVER
GAS MERGER

In considering the recommendation of the Southern Union board with respect to
approving the Fall River Gas merger, you should be aware that members of Fall
River Gas' management and the Fall River Gas board have the following
interests in the merger that may be different from, or in addition to, the
interests of Fall River Gas stockholders generally and represent conflicts of
interest.

EMPLOYMENT AGREEMENTS, TERMINATION OF EMPLOYMENT AND CHANGE-IN-CONTROL
ARRANGEMENTS.  Effective September 30, 1991, Fall River Gas entered into
employment agreements with its President and Chief Executive Officer,
Bradford J. Faxon and with its Senior Vice President, Treasurer and Chief
Financial Officer, Peter H. Thanas.

Under the terms of these employment agreements, Mr. Faxon is compensated for
his duties as an officer and director, and Mr. Thanas is compensated for his
duties as an officer. The amounts of their respective salaries are determined
from time to time by the board of directors. The term of each employment
agreement was initially five years, subject to earlier termination by an act
of Fall River Gas or the respective officer. Beginning in September 1993 and
annually thereafter, the remaining term of each employment agreement is
automatically extended for an additional one-year period. On November 30,
1998, Fall River Gas entered into a similar employment agreement with John F.
Fanning, a Fall River Gas officer.

These employment agreements provide that if the respective officer is
terminated without cause or terminates his employment as a result of certain
adverse actions by Southern Union, during a period of thirty-six months
following a "change in control" of Fall River Gas, the officer shall receive
a lump sum severance amount and continuation of certain welfare plan
benefits. A "change of control" will be considered to have occurred on the
date the merger is completed.

The lump sum severance payment is an amount equal to three times the annual
(or annualized) compensation paid to the respective officer during the period
as of the date of termination. The maximum value of the severance payments
which may become payable to these three officers in the aggregate under the
terms of their agreements is approximately $1,692,000.

On October 4, 1999, these employment agreements were amended. These
amendments will become effective as of the date the Fall River Gas merger is
completed. These amendments provide for payment to Messrs. Faxon, Thanas and
Fanning of $1,000,000; $700,000 and $300,000, respectively. If Southern Union
continues their employment with Fall River Gas, these payments will be made
in equal monthly installments over an eighteen month period beginning on the
effective date of the merger. These payments would be offset against any
severance payments that may become owed under any of the agreements.

DEFENSE, INDEMNIFICATION AND INSURANCE FOR FALL RIVER GAS OFFICERS AND
DIRECTORS. For a period of six years after the completion of the Fall River
Gas merger, Southern Union has agreed to indemnify and hold harmless the
present and former officers and directors of Fall River Gas and its
subsidiary in respect of acts or omissions occurring prior to the completion
of the merger to the extent provided under Fall River Gas' restated articles
of incorporation and bylaws in effect on the date hereof; PROVIDED, HOWEVER,
that if any claim or claims are asserted or made within such six-year period,
all rights to indemnification in respect of such claims shall continue until
the final disposition of any and all such claims.

For six years after the completion of the Fall River Gas merger, Southern
Union will use its reasonable best efforts to provide officers' and
directors' liability insurance in respect of acts or omissions occurring
prior to the completion of the merger covering each such person currently
covered by Fall River Gas' officers' and directors' liability insurance
policy on terms with respect to coverage and amount no less favorable than
those of such policy in effect on the date hereof; PROVIDED THAT, in
satisfying this obligation, if the annual premiums of such insurance coverage
exceed 200% of the previous year's premiums, Southern Union will be obligated
to obtain a policy with the best coverage available, in the reasonable
judgment of Southern


                                       32
<PAGE>

Union's board, for a cost not exceeding such amount. See "The Fall River Gas
Merger Agreement -- Indemnification and Insurance for Fall River Gas Officers
and Directors."

CERTAIN U.S. FEDERAL INCOME TAX CONSEQUENCES OF THE FALL RIVER GAS
MERGER

The following discussion is intended only as a summary of the material U.S.
federal income tax consequences of the Fall River Gas merger to Southern
Union, Fall River Gas and Southern Union stockholders and does not purport to
be a complete analysis or description of all potential tax effects of the
Fall River Gas merger. In addition, the discussion does not address all of
the tax consequences that may be relevant to particular taxpayers in light of
their personal circumstances or to taxpayers subject to special tax rules
(for example, insurance companies, financial institutions, dealers in
securities tax-exempt organizations, banks, foreign taxpayers and taxpayers
holding common stock as parts of straddles). No information is provided with
respect to the tax consequences, if any, of the Fall River Gas merger under
applicable foreign, state, local or other tax laws.

The discussion is based upon the provisions of the Internal Revenue Code,
applicable Treasury regulations thereunder, IRS rulings and judicial
decisions, as in effect as of the date of this proxy statement. There can be
no assurance that future legislative, administrative or judicial changes or
interpretations will not affect the accuracy of the statements or conclusions
included in this proxy statement.  Any such change could apply retroactively
and could affect the accuracy of such discussion.

Each stockholder of Southern Union is urged to consult such stockholder's own
tax advisor as to the specific tax consequences to such stockholder of the
Fall River Gas merger under U.S. federal, state, local or any other
applicable tax laws.

THIS SUMMARY DOES NOT PURPORT TO BE A COMPREHENSIVE DESCRIPTION OF ALL OF THE
TAX CONSIDERATIONS THAT MAY BE RELEVANT TO A DECISION WHETHER TO APPROVE THE
FALL RIVER GAS MERGER. THIS SUMMARY IS PROVIDED FOR GENERAL INFORMATION
PURPOSES ONLY AND DOES NOT CONSTITUTE LEGAL OR TAX ADVICE.

TAX OPINIONS. The obligation of Southern Union to consummate the Fall River
Gas merger is conditioned on its receipt on the closing date of an opinion
from Hughes Hubbard & Reed LLP, tax counsel to Southern Union, that the
merger will qualify as a reorganization under Section 368(a) of the Internal
Revenue Code (the "Southern Union Tax Opinion"). The obligation of Fall River
Gas to consummate the merger is conditioned on its receipt on the closing
date of an opinion from Rich, May, Bilodeau & Flaherty, P.C., Fall River Gas'
counsel, that the merger will qualify as a reorganization under Section
368(a) of the Internal Revenue Code (the "Fall River Gas Tax Opinion").

Each of the Southern Union Tax Opinion and the Fall River Gas Tax Opinion
will be based on certain representations contained in letters from Southern
Union, Fall River Gas and others delivered for the purpose of the opinions
and will be subject to certain limitations and qualifications similar to
those set forth in this discussion of significant U.S. federal income tax
consequences of the Fall River Gas merger. Each of the Southern Union Tax
Opinion and the Fall River Gas Tax Opinion will be based on certain
assumptions, including that the Fall River Gas merger will be consummated
exactly as described in this proxy statement and in the Fall River Gas merger
agreement.

An opinion of counsel represents only counsel's best judgment and has no
binding effect or official status of any kind; and no assurance can be given
that contrary positions will not be taken by the IRS or by a court
considering the issues. Neither Southern Union nor Fall River Gas has
requested or intends to request a ruling from the IRS with regard to any of
the federal income tax consequences of the Fall River Gas merger.

The discussions below of "CONSEQUENCES TO SOUTHERN UNION STOCKHOLDERS" and
"CONSEQUENCES TO SOUTHERN UNION AND FALL RIVER GAS" assume that the Fall
River Gas merger will qualify as a reorganization under Section 368(a) of the
Internal Revenue Code.

CONSEQUENCES TO SOUTHERN UNION STOCKHOLDERS. Southern Union stockholders will
not exchange or otherwise dispose of their Southern Union common stock in the
Fall River Gas merger. They will therefore realize no taxable gain or loss
whatsoever.

CONSEQUENCES TO SOUTHERN UNION AND FALL RIVER GAS. No gain or loss will be
recognized by Southern Union or Fall River Gas by reason of the Fall River
Gas merger.

REGULATORY APPROVALS FOR THE FALL RIVER GAS MERGER

The following is a summary of the material regulatory requirements affecting
the Fall River Gas merger. There can be no guarantee if and when any of the
consents or approvals required for the merger will be obtained or as to the
conditions that they may contain. Southern Union and Fall River Gas have
filed for the required approvals from all of the agencies discussed. The
management of Southern Union and Fall River Gas, respectively, believe that
the necessary approvals can be obtained in 2000 and presently expect that
they all will be received by September 2000.

STATE APPROVALS AND RELATED MATTERS. The utility operations of Southern Union
are subject to the regulatory jurisdiction of the Missouri Public Service
Commission ("MPSC"), the Pennsylvania Public Utility Commission ("PPUC"), the
Railroad Commission of Texas ("RRC") and various municipalities in Texas
where Southern Union conducts business, and the Florida Public Service
Commission ("FPSC"). On May 11, 2000, the PPUC approved the Fall River Gas
merger. The MPSC approved Fall River Gas merger on June 28, 2000.
Authorization from the FPSC and the PPUC with respect to the securities that
may be issued and debt that may be assumed by Southern Union in connection
with the Fall River Gas merger is also required. None of the other required
state approvals had been received as of the date of this proxy statement. No
RRC or Texas municipality approvals are required in connection with the
merger.

The utility operations of Fall River Gas are subject to the regulatory
jurisdiction of the Massachusetts Department of Telecommunications and Energy
("MDTE") and subsequent to the Fall River Gas merger, those operations,
conducted as a division of Southern Union, will remain subject to MDTE
jurisdiction. Among the key provisions are those addressing rates and
charges, standards of service, and accounting and approval of certain
financing transactions.

Subsequent to the execution of the Fall River Gas merger agreement, the issue
arose as to whether Southern Union was required under Massachusetts law to
obtain the approval of the transaction by holders of two-thirds of the
outstanding shares of Southern Union common stock in connection with
obtaining the approval of the transaction by the MDTE. In order to eliminate
any uncertainty concerning this issue and to facilitate the closing of the
transaction, Southern Union advised Fall River Gas and the MDTE that it
intends to seek, and through this proxy statement at the Southern Union
special meeting it is seeking, such stockholder approval.

Assuming the requisite regulatory approvals are obtained, the combined
company and its utility operations will remain subject to the regulatory
jurisdiction of the MDTE, MPSC, PPUC, RRC and various municipalities in
Texas, and the FPSC. Upon completion of the Valley Resources and ProvEnergy
mergers, the combined company and its utility operations will also be subject
to the regulatory jurisdiction of the Rhode Island Public Utilities
Commission and the Rhode Island Division of Public Utilities and Carriers.

ANTI-TRUST CONSIDERATIONS.  Under the HSR Act, Southern Union and Fall River
Gas cannot complete the Fall River Gas merger until we give notification and
furnish information to the Federal Trade Commission ("FTC") and the Antitrust
Division of the Department of Justice and the specified waiting period
requirements have been satisfied. Southern Union and Fall River Gas filed the
required notification and report forms with the FTC and the Antitrust
Division on March 1, 2000. A request for additional information from the FTC
was received on March 31, 2000, to which Southern Union and Fall River Gas
have responded. At any time before or after the effective time of the Fall
River Gas merger, and notwithstanding that the waiting period has terminated
or the Fall River Gas merger may have been consummated, the FTC, the
Antitrust Division or any state could take any action under the applicable
antitrust or competition laws as it deems necessary or desirable. This action
could include seeking to enjoin the completion of the Fall River Gas merger.
Private parties may also institute legal actions under the antitrust laws
under some circumstances. If the Fall River Gas merger is not consummated
within twelve months after the expiration or earlier termination of the HSR
Act waiting period, Southern Union and Fall River Gas would be required to
submit new filings to the Department of Justice and the FTC, and a new HSR
Act waiting period would have to expire or be earlier terminated before the
merger could be consummated.

ACCOUNTING TREATMENT FOR THE FALL RIVER GAS MERGER

The Unaudited Pro Forma Combined Condensed Financial Statements appearing
elsewhere in this proxy statement are based upon certain assumptions, as
described in the pro forma combined condensed financial statements, and are
included for informational purposes only. The Fall River Gas merger will be
accounted for using the purchase method of accounting, in accordance with
generally accepted accounting principles. Under the purchase method of
accounting, Southern Union's historical results for periods before the Fall
River Gas merger will remain unchanged. On the closing date, the combined


                                       34
<PAGE>

company will record Fall River Gas' assets and liabilities of regulated
entities at their historical cost basis, and Fall River Gas' assets and
liabilities of non-regulated entities will be recorded at fair value, with
any excess recorded as additional purchase cost assigned to utility plant.
See "Unaudited Pro Forma Combined Condensed Financial Statements."

LISTING OF SOUTHERN UNION COMMON STOCK

It is a condition to the completion of the Fall River Gas merger that the
shares of Southern Union common stock to be issued in connection with the
merger be approved for listing on the NYSE at or before the time the merger
is completed. See "The Fall River Gas Merger Agreement -- Conditions to the
Completion of the Fall River Gas Merger."

FEDERAL SECURITIES LAW CONSEQUENCES

All shares of Southern Union common stock received by Fall River Gas
stockholders in connection with the merger will be freely transferable,
except that shares of Southern Union common stock received by individuals and
entities who are deemed to be "affiliates" (as such term is defined under the
Securities Act) of Fall River Gas before the merger may be resold by them
only in transactions permitted by the resale provisions of Rule 145 under the
Securities Act (or Rule 144 under the Securities Act, in the case of
individuals and entities who become affiliates of Southern Union) or as
otherwise permitted under the Securities Act.

Persons who may be deemed to be affiliates of Southern Union or Fall River
Gas generally include individuals or entities that control, are controlled
by, or are under common control with, Southern Union or Fall River Gas and
may include certain officers and directors of Southern Union or Fall River
Gas as well as principal stockholders of Southern Union or Fall River Gas.
The merger agreement requires Fall River Gas to use commercially reasonable
efforts to cause each of its affiliates to execute and deliver to Southern
Union a letter to the effect that such affiliate will not offer or sell or
otherwise dispose of Southern Union common stock issued to such affiliate in
or pursuant to the Fall River Gas merger in violation of the Securities Act
or the rules and regulations adopted by the SEC thereunder. See "The Fall
River Gas Merger Agreement -- Covenants and Other Agreements -- Certain Other
Covenants and Agreements." The delivery of such agreements is also a
condition to Southern Union's obligation to complete the merger. See "The
Fall River Gas Merger Agreement -- Conditions to the Completion of the Fall
River Gas Merger -- Additional Closing Conditions for Southern Union's
Benefit."

                              THE PROVENERGY MERGER

THIS SECTION OF THE PROXY STATEMENT, AS WELL AS THE SECTION ENTITLED "THE
PROVENERGY MERGER AGREEMENT," DESCRIBES CERTAIN ASPECTS OF THE PROPOSED
MERGER WITH PROVENERGY. THESE SECTIONS HIGHLIGHT KEY INFORMATION ABOUT THE
PROVENERGY MERGER AND THE PROVENERGY MERGER AGREEMENT, BUT THEY MAY NOT
INCLUDE ALL THE INFORMATION THAT YOU WOULD LIKE TO KNOW. THE MERGER AGREEMENT
BETWEEN PROVENERGY AND SOUTHERN UNION IS ATTACHED AS APPENDIX C TO THIS PROXY
STATEMENT. WE URGE YOU TO READ THE PROVENERGY MERGER AGREEMENT IN ITS
ENTIRETY.

SOUTHERN UNION BACKGROUND OF THE PROVENERGY MERGER

For the past several years, Southern Union has pursued acquisition and
business combination opportunities. After the announcement of its merger
agreement with PEI, Southern Union management sought additional opportunities
in the northeastern United States that could expand its presence in that
region.

In late July, 1999, Mr. Thomas F. Karam, the President and Chief Executive
Officer of PEI, an energy company that had agreed to be acquired by Southern
Union (and was subsequently acquired on November 4, 1999), telephoned Mr.
James Dodge, the Chairman, Chief Executive Officer and President of
ProvEnergy, to propose a meeting to discuss Southern Union's interest in
acquiring ProvEnergy. Mr. Dodge and Mr. Karam met in Providence on August 2,
1999 for preliminary discussions. Mr. Dodge, Mr. James DeMetro, the Executive
Vice President of ProvEnergy, Mr. Karam and Mr. Peter H. Kelley, the
President and Chief Operating Officer of Southern Union, met on August 10,
1999 and discussed their respective views of the industry, strategic
directions and management philosophies of each company, and the potential
benefits of a business combination transaction involving the companies. On
September 13, 1999, Mr. Dodge, Mr. DeMetro, and Mr. Kenneth Hogan, the Vice
President and Chief Financial Officer and Treasurer of ProvEnergy, met with
Mr. Karam, Mr. Ronald Simms, Chairman of PEI, Mr. Kelley and other members of
Southern Union's senior management in Austin, Texas to continue discussions
about a possible acquisition of ProvEnergy by Southern Union. On September
22, 1999, Mr. Dodge met in White Sulphur Springs, West Virginia with George
L. Lindemann, the Chairman of the Board and Chief Executive Officer of
Southern Union, and Messrs. Karam and Kelley to discuss the prospective
business strategy and management organization of a combined entity.

On September 24, 1999, Southern Union's legal advisor delivered an initial
draft of a merger agreement to ProvEnergy and ProvEnergy's legal advisors.

During the next three weeks there were various meetings and discussions among
representatives of Southern Union and ProvEnergy and their advisors regarding
the transaction structure, the form and amount of the merger consideration,
the management of the combined company and other material terms. During this
time the parties also executed a confidentiality agreement and commenced due
diligence investigations and discussions with respect to each other, and
ProvEnergy retained regulatory counsel.

On October 21, 1999, the ProvEnergy board of directors met to discuss the
current status of the proposed transaction with Southern Union.

During the next three weeks there were numerous meetings and telephone calls
among the senior management and legal advisors of Southern Union and
ProvEnergy and representatives of Salomon Smith Barney, ProvEnergy's
financial advisor, concerning the proposed merger agreement and the proposed
employment agreements between Southern Union and Messrs. Dodge and DeMetro.
During this time the parties completed their due diligence investigations and
it was agreed, among other things, that the merger consideration would be
paid entirely in cash.

On November 10, 1999, the Board of Directors of Southern Union unanimously
approved a merger with ProvEnergy and authorized its Executive Committee to
negotiate the definitive merger agreement.

On November 11, 1999, members of senior management of Southern Union and
ProvEnergy, their respective legal advisors and representatives of Salomon
Smith Barney met in New York City to finalize the terms of the ProvEnergy
merger agreement, the employment agreements and related documentation. The
primary terms discussed were the purchase price, the termination fee and the
conditions to closing. On November 12, 1999, the Executive Committee of
Southern Union unanimously authorized Mr. Kelley and Southern Union's
Executive Vice President, Ronald J. Endres, to enter into a merger agreement
with ProvEnergy for an all cash merger consideration of $42.50 per share.
Thereafter, representatives of Southern


                                       36
<PAGE>

Union and ProvEnergy continued to finalize the terms of the merger agreement,
the employment agreements and related documentation.

On the evening of November 14, 1999, the ProvEnergy board of directors met
with Messrs. Kelley and Karam in Providence, Rhode Island.

On the morning of November 15, 1999, the ProvEnergy board of directors held a
special meeting to review and consider the proposed transaction with Southern
Union. The ProvEnergy board of directors unanimously determined that it was
in the best interests of ProvEnergy and its shareholders, as well as for the
community, customers and employees of ProvEnergy, for ProvEnergy to merge
with Southern Union and determined that the terms of the merger agreement and
the transactions contemplated thereby were fair to and in the best interests
of ProvEnergy and its shareholders and approved the ProvEnergy merger
agreement and the transactions contemplated thereby. Following the ProvEnergy
board of directors meeting, the merger agreement, the employment agreements
and related documentation were executed and delivered, and the parties issued
a joint press release announcing the transaction.

Subsequent to the execution of the merger agreement, the issue arose as to
whether Southern Union was required under Massachusetts law to obtain the
approval of the ProvEnergy merger by holders of two-thirds of the outstanding
shares of Southern Union common stock in connection with obtaining the
approval by the Massachusetts Department of Telecommunications and Energy of
Southern Union's acquisition of North Attleboro Gas, ProvEnergy's
Massachusetts utility subsidiary. In order to eliminate any uncertainty
concerning this issue and to facilitate the closing of the transaction,
Southern Union advised ProvEnergy and the Massachusetts Department of
Telecommunications and Energy that it intends to seek, and as of the date of
this document it is seeking, such stockholder approval.

SOUTHERN UNION'S REASONS FOR THE PROVENERGY MERGER

In reaching its determination that a merger with ProvEnergy is in the best
interest of Southern Union, its stockholders, customers and employees, the
Southern Union board of directors, including its Executive Committee,
consulted with and relied upon information and reports prepared or presented
by Southern Union's management and Southern Union's legal advisors. The
following are the material factors considered by the Southern Union board,
including its Executive Committee, in pursuing acquisition opportunities,
generally, which are relevant to their approval of a merger agreement with
ProvEnergy, some of which contained both positive and negative elements:

-    the terms of a proposed form of merger agreement consistent with those
     terms described under "The ProvEnergy Merger Agreement";

-    the likelihood of receipt of timely and satisfactory regulatory
     approvals for the merger;

-    the risk that the merger would not be consummated;

-    other recent and potential mergers involving utilities in the northeastern
     region of the country, particularly PEI, Fall River Gas and Valley
     Resources;

-    the substantial management time and effort that will be required to
     consummate all aspects of the recent and prospective mergers, including to
     integrate the operations of those companies, and the risks inherent in such
     integration;

-    other matters described under "Forward-Looking Statements May Prove
     Inaccurate"; and

-    the results of Southern Union's business investigation of
     ProvEnergy and its subsidiaries.

The foregoing discussion of the information and factors considered by the
Southern Union board, including its Executive Committee, is not intended to
be all-inclusive. In view of the wide variety of factors considered in
connection with its evaluation of acquisition opportunities, including this
proposed merger, the Southern Union board, including its Executive Committee,
did not find it practicable to, and did not, quantify or otherwise attempt to
assign relative weights to the foregoing factors. Rather, the Southern Union
board, including its Executive Committee, based its decision on the totality
of the information presented to and considered by it.

RECOMMENDATION OF SOUTHERN UNION'S BOARD OF DIRECTORS

On May 31, 2000, the Southern Union Board of Directors approved a resolution
recommending that the stockholders of Southern Union approve the ProvEnergy
merger at a special meeting of stockholders, due to the merger being in the
best interests of Southern Union, its stockholders, employees and customers,
and the desire to avoid unnecessary delay in the receipt of certain
regulatory approvals as previously explained.

INTERESTS OF PROVENERGY OFFICERS AND DIRECTORS IN THE PROVENERGY
MERGER

In considering the recommendation of the Southern Union board of directors
that you vote for the ProvEnergy approval of the merger agreement, you should
be aware that certain directors and executive officers of ProvEnergy have
interests in the ProvEnergy merger in addition to their interests solely as
ProvEnergy shareholders. These interests may create potential conflicts of
interest.

EMPLOYMENT AGREEMENTS. In connection with the ProvEnergy merger agreement,
Southern Union entered into an employment agreement with Mr. James H. Dodge,
which will become effective upon the consummation of the initial merger of
GUS into ProvEnergy. The employment agreement provides for an initial three
year term, with automatic extensions so that the agreement continuously has a
three year remaining term until Mr. Dodge attains age 62, at which time the
term shall become fixed at three years. The agreement provides Mr. Dodge with
a base salary of $400,000, continues his opportunity to earn an annual
incentive bonus (which must be equal to at least 50% of his base salary), and
enhances his retirement benefits. Mr. Dodge will receive a $1,000,000 bonus
payable at the effective time of the initial merger and two subsequent annual
bonuses of $500,000. If Mr. Dodge's employment is terminated without "cause"
or if Mr. Dodge terminates his employment for "good reason" (as such terms
are defined in the employment agreement), Mr. Dodge will receive payment of
all unpaid bonuses and incentive awards for the remainder of the three year
term, as well as continued provision of company health, life and disability
benefits until Mr. Dodge reaches age 65 (or for three years following his
termination, if later), with post-retirement health benefits provided to Mr.
Dodge and his spouse thereafter.

In connection with the ProvEnergy merger agreement, Southern Union entered
into an amendment to the employment agreement of Mr. James DeMetro, which
will become effective upon the consummation of the initial merger. This
amendment provides Mr. DeMetro with a $500,000 bonus payable at the effective
time of the initial merger, enhances his retirement benefits and expands the
definition of good reason to include the failure to renew his employment
agreement.

BOARD OF DIRECTORS AND OFFICERS OF SOUTHERN UNION. Immediately after the
effective time of the initial merger on the closing date, Mr. James H. Dodge,
the Chief Executive Officer of ProvEnergy, will be elected to the board of
directors of Southern Union and thereafter will be nominated for reelection,
if necessary, so that he will have a term of at least three years from the
closing date.

In addition, from the effective time of the initial merger until the earlier
of their resignation or removal by the President of Southern Union:

-     Mr. James H. Dodge will serve as Chief Executive Officer and
     President of the ProvEnergy and North Attleboro divisions of
     Southern Union and all other energy-related businesses of Southern
     Union conducted in New England, and

-    Mr. James DeMetro will serve as Executive Vice President, Energy Services,
     of the ProvEnergy and North Attleboro divisions of Southern Union and all
     other energy-related businesses of Southern Union conducted in New England.

See "The ProvEnergy Merger Agreement -- Covenants and Other Agreements,
including Post-Closing Commitments -- Employees; Benefits" which sets forth
the positions of other ProvEnergy executives after the initial merger.

DEFENSE, INDEMNIFICATION AND INSURANCE FOR PROVENERGY OFFICERS AND DIRECTORS.
Under the ProvEnergy merger agreement, Southern Union agreed for a period of
six years after the effective time of the initial merger to indemnify and
hold harmless the present and former officers and directors of ProvEnergy and
its subsidiaries in respect of acts or omissions occurring prior to the
effective time to the extent provided under ProvEnergy's articles of
incorporation and bylaws. In addition, subject to specified limitations,
Southern Union agreed to use its reasonable best efforts to provide officers'
and directors' liability insurance for acts and omissions occurring before
the ProvEnergy merger on terms with respect to coverage and


                                       38
<PAGE>

amount that are no less favorable to the terms in effect on the date of
the ProvEnergy merger agreement. See "The ProvEnergy Merger Agreement --
Indemnification and Insurance for ProvEnergy Officers and Directors."

CERTAIN FEDERAL INCOME TAX CONSEQUENCES OF THE PROVENERGY MERGER

The following discussion is intended only as a summary of the material U.S.
federal income tax consequences of the ProvEnergy merger to ProvEnergy,
Southern Union and Southern Union stockholders and does not purport to be a
complete analysis or description of all potential tax effects of the merger.
In addition, the discussion does not address all of the tax consequences that
may be relevant to particular taxpayers in light of their personal
circumstances or to taxpayers subject to special tax rules (for example,
insurance companies, financial institutions, dealers in securities,
tax-exempt organizations, banks, foreign taxpayers and taxpayers holding
common stock as parts of straddles). No information is provided with respect
to the tax consequences, if any, of the merger under applicable foreign,
state, local or other tax laws.

The discussion is based upon the provisions of the Internal Revenue Code,
applicable Treasury regulations thereunder, IRS rulings and judicial
decisions, as in effect as the date of this proxy statement. There can be no
assurance that future legislative, administrative or judicial changes or
interpretations will not affect the accuracy of other statements or
conclusions set forth herein. Any such change could apply retroactively and
could affect the accuracy of such discussion.

THIS SUMMARY DOES NOT PURPORT TO BE A COMPREHENSIVE DESCRIPTION OF ALL OF THE
TAX CONSIDERATIONS THAT MAY BE RELEVANT TO A DECISION WHETHER TO APPROVE THE
PROVENERGY MERGER. THIS SUMMARY IS PROVIDED FOR GENERAL INFORMATION PURPOSES
ONLY AND DOES NOT CONSTITUTE LEGAL OR TAX ADVICE.

CONSEQUENCES TO SOUTHERN UNION STOCKHOLDERS. Southern Union stockholders will
not exchange or otherwise dispose of their Southern Union common stock in the
ProvEnergy merger. They will therefore realize no taxable gain or loss
whatsoever.

CONSEQUENCES TO SOUTHERN UNION AND PROVENERGY. No gain or loss will be
recognized by Southern Union or ProvEnergy by reason of the ProvEnergy merger.

REGULATORY APPROVALS FOR THE PROVENERGY MERGER

The following is a summary of the material regulatory requirements affecting
the ProvEnergy merger. There can be no guarantee if and when any of the
consents or approvals required for the ProvEnergy merger will be obtained or
as to the conditions that they may contain. Southern Union and ProvEnergy
have filed for the required approvals from all of the agencies discussed. The
management of Southern Union and ProvEnergy, respectively, believe that the
necessary approvals can be obtained in 2000 and presently expect that they
will all be received by September 2000.

STATE APPROVALS AND RELATED MATTERS. The utility operations of Southern Union
are subject to the regulatory jurisdiction of the MPSC, the PPUC, the RRC and
various municipalities in Texas where Southern Union conducts business, and
the FPSC. The FPSC and PPUC must approve certain related financing
arrangements. The PPUC approved the ProvEnergy merger on May 11, 2000. On
June 28, 2000, the MPSC approved the ProvEnergy merger. No other state
approvals have been received as of the date of this proxy statement. No RRC
or Texas municipality approvals are required in connection with the merger.

The utility operations of ProvEnergy are subject to the jurisdiction of the
Rhode Island Public Utilities Commission ("RIPUC") and the Rhode Island
Division of Public Utilities and Carriers ("RIDPUC"), and the utility
operations of its wholly-owned subsidiary, North Attleboro Gas, are subject
to the jurisdiction of the Massachusetts Department of Telecommunications and
Energy ("MDTE"), with respect to rates and charges, standards of service,
accounting and other matters including certain financing transactions.

The Federal Energy Regulatory Commission's ("FERC") approval, required to
complete the merger of Southern Union and ProvEnergy, was obtained in June
2000, effective as of the closing date of the merger.

The approvals of the MDTE and if necessary, RIDPUC, are required to complete
the ProvEnergy merger.

Subsequent to the execution of the ProvEnergy merger agreement, the issue
arose as to whether Southern Union was required under Massachusetts law to
obtain the approval of the transaction by holders of two-thirds of the
outstanding shares of Southern Union common stock in connection with
obtaining the approval of the North Attleboro Gas merger by the MDTE.


                                       39
<PAGE>

In order to eliminate any uncertainty concerning this issue and to facilitate
the closing of the transaction, Southern Union has advised ProvEnergy and the
MDTE that it intends to seek, and through this proxy statement at the
Southern Union special meeting is seeking, such stockholder approval.

Assuming the requisite regulatory approvals are obtained, the combined
company and its utility operations will remain subject to the regulatory
jurisdiction of the MDTE, MPSC, PPUC, RRC and various municipalities in
Texas, the FPSC, RIPUC and RIDPUC.

ANTI-TRUST CONSIDERATIONS. Under the HSR Act, Southern Union and ProvEnergy
cannot complete the ProvEnergy merger until both companies give notification
and furnish information to the FTC and the Antitrust Division of the
Department of Justice and the specified waiting period requirements have been
satisfied. Southern Union and ProvEnergy filed the required notification and
report forms with the FTC and the Antitrust Division on March 1, 2000. A
request for additional information from the FTC was received on March 31,
2000, to which Southern Union and ProvEnergy have responded. At any time
before or after the effective time of the ProvEnergy merger, and
notwithstanding that the waiting period has terminated or the ProvEnergy
merger may have been consummated, the FTC, the Antitrust Division or any
state could take any action under the applicable antitrust or competition
laws as it deems necessary or desirable. This action could include seeking to
enjoin the completion of the ProvEnergy merger. Private parties may also
institute legal actions under the antitrust laws under some circumstances. If
the ProvEnergy merger is not consummated within twelve months after the
expiration or earlier termination of the HSR Act waiting period, Southern
Union and ProvEnergy would be required to submit new filings to the
Department of Justice and the FTC, and a new HSR Act waiting period would
have to expire or be earlier terminated before the merger could be
consummated.

See "The ProvEnergy Merger Agreement -- Conditions to Completion of the
ProvEnergy Merger."

ACCOUNTING TREATMENT FOR THE PROVENERGY MERGER

The Unaudited Pro Forma Combined Condensed Financial Statements appearing
elsewhere in this proxy statement are based upon certain assumptions, as
described in the pro forma combined condensed financial statements, and are
included for informational purposes only. The ProvEnergy merger will be
accounted for using the purchase method of accounting, in accordance with
generally accepted accounting principles. Under the purchase method of
accounting, Southern Union's historical results for periods before the
ProvEnergy merger will remain unchanged. On the closing date, the combined
company will record ProvEnergy's assets and liabilities of regulated entities
at their historical cost basis and ProvEnergy's assets and liabilities of
non-regulated entities will be recorded at fair value with any excess
recorded as additional purchase cost assigned to utility plant. See
"Unaudited Pro Forma Combined Condensed Financial Statements."

                            MERGER-RELATED FINANCING

Southern Union's management is evaluating various sources and methods of
financing the amount necessary to fund the cash portion of the consideration
to be paid to Fall River Gas stockholders, the all cash consideration to be
paid to the ProvEnergy and Valley Resources stockholders, and all related
costs and refinancings anticipated in connection with these mergers. Southern
Union's management currently anticipates that substantially all of these
costs will be financed through external sources. Southern Union anticipates
soliciting consents from the holders of the mortgage bonds and debentures of
Fall River Gas, ProvEnergy and Valley Resources to revise or eliminate
certain of their indenture terms, primarily to conform to certain terms in
the indenture for Southern Union's outstanding senior notes.

Southern Union's pending acquisitions of Fall River Gas, ProvEnergy and
Valley Resources would require up to approximately $600 million of new
financing if Fall River Gas shareholders choose to receive the maximum of 50%
of the aggregate merger consideration that may be paid to them in cash and if
all of the approximately $140 million of existing long-term debt of the three
companies being acquired must be refinanced rather than amended and assumed
as planned. Presently, Southern Union expects to be able to amend the terms
of outstanding long-term debt of the three companies being acquired in order
to assume such debt. Southern Union presently plans to fund all other costs
for the three acquisitions with bank borrowings, although it has not yet
received commitments.

After closing the mergers, Southern Union may choose or need to refinance
some portion or all of the bank borrowings that it plans for funding the
pending acquisitions. Sources of future or alternative financing that
Southern Union may consider include commercial and investment banks,
institutional lenders, institutional investors and public securities markets.
The methods of financing that Southern Union may consider include bank lines
of credit, debt and preferred securities of various maturities and terms, and
common stock. Southern Union's management believes that Southern Union will
have access if and when needed to many sources and types of short-term and
long-term capital sources at reasonable rates.

All of these considerations and assumptions relate to the financing required
for the mergers and acquisitions that Southern Union has agreed to consummate
but not completed. As a result of its planned financing and as shown in the
Pro Forma Combined Condensed Financial Statements, the consolidated
capitalization of Southern Union after completion of Southern Union's three
pending mergers is expected to consist of at least 32% common equity,
approximately 5% preferred equity and approximately 63% long-term debt.

                          NO STATUTORY APPRAISAL RIGHTS

Under Delaware law, you do not have appraisal rights in connection with the Fall
River Gas and ProvEnergy mergers.

                       THE FALL RIVER GAS MERGER AGREEMENT

THIS SECTION IS A SUMMARY OF THE MATERIAL TERMS OF THE FALL RIVER GAS MERGER
AGREEMENT, A COPY OF WHICH IS ATTACHED AS APPENDIX A TO THIS DOCUMENT. THE
FOLLOWING DESCRIPTION DOES NOT PURPORT TO BE COMPLETE AND IS QUALIFIED IN ITS
ENTIRETY BY REFERENCE TO THE FALL RIVER GAS MERGER AGREEMENT. YOU SHOULD REFER
TO THE FULL TEXT OF THE FALL RIVER GAS MERGER AGREEMENT FOR DETAILS OF THE
MERGER AND THE TERMS AND CONDITIONS OF THE MERGER AGREEMENT.

STRUCTURE OF THE MERGER

Under the Fall River Gas merger agreement, Fall River Gas will be merged with
and into Southern Union. After the merger, Southern Union will continue as the
surviving corporation. Southern Union's existing charter and bylaws will
remain in effect after the Fall River Gas merger and Southern Union's
management and board of directors will remain the same as a result of the Fall
River Gas merger, except as specifically discussed in this proxy statement.
See "Possible Effects of the Mergers on Southern Union Stockholder Rights."

As a result of the Fall River Gas merger, Fall River Gas will be a division of
Southern Union. Fall River Gas' non-regulated subsidiary will become a
subsidiary of Southern Union.

CLOSING; EFFECTIVE TIME

On the closing date of the Fall River Gas merger, we will file articles of
merger and a certificate of merger with the Secretary of State of the
Commonwealth of Massachusetts in accordance with the Massachusetts General
Laws ("MGL") and a certificate of merger with the Secretary of State of the
State of Delaware in accordance with the Delaware General Corporation Law
("DGCL"). The Fall River Gas merger will become effective upon filing of these
documents. This moment is referred to as the "effective time."

FALL RIVER GAS MERGER CONSIDERATION

Fall River Gas stockholders have the option to elect either cash or Southern
Union common stock or a combination of both in exchange for their shares of
Fall River Gas common stock, subject to certain limitations.

Each share of Fall River Gas common stock that a stockholder elects to
exchange for cash will be converted into the right to receive $23.50 in cash,
unless too many Fall River Gas stockholders elect to receive cash. No more
than 50% of the aggregate consideration paid to all Fall River Gas
stockholders may consist of cash, including cash paid to Fall River Gas
stockholders in lieu of issuing them fractional shares of Southern Union
common stock. If the Fall River Gas stockholders exceed this cash limitation,
the amount of cash paid to each Fall River Gas stockholder electing cash will
be reduced proportionately. Thus, if too many Fall River Gas stockholders
elect to receive cash, consequently exceeding the cash limitation, a
combination of cash and Southern Union common stock having a deemed value of
$23.50 will be delivered to Fall River Gas stockholders in exchange for each
share they selected to be exchanged for cash.

Each share of Fall River Gas common stock that a stockholder elects to
exchange for Southern Union common stock, will be converted into the right to
receive that number of whole shares of Southern Union common stock having a
value of $23.50. Southern Union will not issue any fractional shares of its
common stock in connection with the Fall River Gas merger. Instead, Fall River
Gas stockholders will be given cash for any fractional shares of Southern
Union common stock they would otherwise receive.

The exact number of shares of Southern Union common stock a Fall River Gas
stockholder will receive for each share of Fall River Gas common stock will
depend on the average trading price of Southern Union common stock on the New
York Stock Exchange for the ten trading day period beginning on the twelfth
trading day and ending on the third trading day before the closing of the
merger (counting from and including the trading day immediately preceding the
closing).

If the average price of Southern Union's common stock during this ten trading
day period is:

-    Above $19.6875, the number of shares of Southern Union common stock will
     be fixed at 1.19365 for each share of Fall River Gas common stock.

                                     42

<PAGE>

-    Between $16.875 and $19.6875, the number of shares of Southern Union
     common stock will be adjusted so that each share of Fall River Gas' common
     stock will be exchanged for Southern Union common stock having a value
     equal to $23.50 divided by the average trading price during the period of
     time described above.

-    Below $16.875, but at least $15.00, the number of shares of Southern Union
     common stock will be fixed at 1.39259 for each share of Fall River Gas
     common stock.

-    Below $15.00, Fall River Gas has the option to terminate the Fall River
     Gas merger agreement. If Fall River Gas does not terminate the merger
     agreement, Fall River Gas stockholders will receive 1.39259 shares of
     Southern Union common stock per share of Fall River Gas common stock.

REPRESENTATIONS AND WARRANTIES

The Fall River Gas merger agreement contains certain substantially mutual
representations and warranties made by Southern Union and Fall River Gas to
each other, relating to, among other things:

See "The Fall River Gas Merger - Interests of Fall River Gas Officers and
Directors in the Fall River Gas Merger."

NO SOLICITATION BY FALL RIVER GAS

The Fall River Gas merger agreement provides that Fall River Gas must
terminate all existing discussions or negotiations with third parties, if any,
with respect to a "Business Combination," as define below, and that Fall River
Gas may not, and may not authorize or permit its or its subsidiary's officers,
directors, agents, financial advisors, attorneys, accountants or other
representatives to, directly or indirectly:

-    solicit, initiate or encourage submission of proposals or offers relating
     to, or that could reasonably be expected to lead to, a Business
     Combination; or

-    participate in any negotiations or discussions regarding, furnish to any
     person any information with respect to, or otherwise cooperate, assist,
     participate in, facilitate or encourage any effort or attempt by any other
     person to do or seek, a Business Combination.

A "Business Combination" is, except as provided in the Fall River Gas merger
agreement:

-    a merger, consolidation or other business combination, share exchange,
     sale of shares of capital stock, tender offer or exchange offer or similar
     transaction involving Fall River Gas or its subsidiary;

                                     47

<PAGE>

-    the acquisition in any manner, directly or indirectly, of a material
     interest in any capital stock of, or a material equity interest in a
     substantial portion of the assets of, Fall River Gas or of its subsidiary,
     including any single or multi-step transaction or series of related
     transactions that is structured to permit a third party to acquire
     beneficial ownership of a majority or greater equity interest in Fall
     River Gas or its subsidiary; or

-    the acquisition in any manner, directly or indirectly, of any material
     portion of the business or assets (other than immaterial or insubstantial
     assets or inventory in the ordinary course of business or assets held for
     sale) of Fall River Gas or its subsidiary.

Prior to receiving the approval of the Fall River Gas merger by Fall River Gas
stockholders, if the Fall River Gas board of directors receives an unsolicited
written proposal from a third party with respect to a Business Combination
that the Fall River Gas board of directors determines, in its good faith
judgment, after consulting with its financial advisor and outside counsel,
with customary qualifications, is a "Superior Proposal," which we define
below, Fall River Gas may:

-    furnish information to, and negotiate, explore or otherwise engage in
     substantive discussions with the third party that submitted the
     unsolicited Superior Proposal if the Fall River Gas board determines that
     it is reasonably necessary to engage in such discussions in order to
     comply with its fiduciary duties under applicable law; and

-    take and disclose to Fall River Gas' stockholders a position with respect
     to another Business Combination proposal, or amend or withdraw such
     position, pursuant to Rule 14d-9 and 14e-2 under the Exchange Act, or make
     such disclosure to Fall River Gas' stockholders which in the good faith
     judgment of the Fall River Gas board of directors is required by
     applicable law, based on the advice of its outside counsel.

A proposed Business Combination is a "Superior Proposal" if it involves at
least 50% of the shares of capital stock or a material portion of the assets
of Fall River Gas and the Fall River Gas board determines, after consulting
with Fall River Gas' financial advisor and outside counsel, that:

-    the proposal is financially superior to the Fall River Gas merger; and

-    it appears that the party making the proposal is reasonably likely to have
     the funds necessary to consummate the Business Combination.


The Fall River Gas merger agreement also prohibits the Fall River Gas board
from withdrawing or modifying, or proposing publicly to withdraw or modify, in
a manner adverse to Southern Union, its approval or recommendation of the
merger agreement or the merger, approving or recommending, or proposing
publicly to approve or recommend, a Business Combination, or causing Fall
River Gas to enter into any letter of intent, agreement in principle,
acquisition agreement or other similar agreement related to any Business
Combination unless the following conditions are satisfied:

-    the Fall River Gas board determines, in its good faith judgment, after
     consulting with its financial advisor and outside counsel, that an
     unsolicited proposal regarding a Business Combination is a Superior
     Proposal; and

-    the Fall River Gas board determines, in its good faith judgment, after
     consulting with its financial advisor and outside counsel, that the
     failure to either withdraw or modify its approval or recommendation of the
     Fall River Gas merger agreement or the Fall River Gas merger, approve or
     recommend a Business Combination, or cause Fall River Gas to enter into
     any agreement related to any Business Combination would create a
     reasonable possibility of a breach of the fiduciary duties of the Fall
     River Gas board under applicable law.

Fall River Gas must promptly notify Southern Union of the receipt of any
alternative acquisition proposal regarding a Business Combination, the
material terms and conditions of any such proposal, the identity of the person
or entity making the proposal and the status and details of any such request
or proposal within one business day of Fall River Gas' receipt of any such
proposal. Fall River Gas is required to use all reasonable efforts to keep
Southern Union informed of the status and details of any such inquiry, offer
or proposal and provide notice, consisting of two days, to Southern Union
prior to the first delivery of non-public information to any such person or
entity. If any such inquiry, offer or proposal is in writing, Fall River Gas
has agreed to promptly deliver to Southern Union a copy of such inquiry, offer
or proposal. If Fall River Gas decides to accept such a Business Combination
proposal and enter into a definitive agreement with respect to such proposal,

                                     48

<PAGE>

Fall River Gas must give Southern Union notice, consisting of five business
days, of its intent to enter into a definitive agreement. In addition, during
this five-day period, Fall River Gas must give Southern Union an opportunity
to adjust the terms of the Fall River Gas merger agreement so that the parties
can proceed with the Fall River Gas merger and negotiate in good faith with
Southern Union with respect to any such adjustments. Concurrently with the
termination of the Fall River Gas merger agreement in connection with a
Business Combination, Fall River Gas must also pay the required termination
fee (see "-- Termination of the Fall River Gas Merger Agreement" and "--
Termination Fees and Expenses -- Fall River Gas Termination Fee").

Prior to furnishing any non-public information to, entering into negotiations
with or accepting a Superior Proposal from a third party, Fall River Gas will
provide written notice to Southern Union to the effect that it is furnishing
information to or entering into discussions or negotiations with such third
party and receive from such third party an executed confidentiality agreement
containing substantially the same terms and conditions as the confidentiality
agreement between Fall River Gas and Southern Union.

     -   less than two-thirds of the holders of the outstanding common stock of
         Fall River Gas vote to approve the merger and there has not been a

         River Gas merger agreement;

     -   the Fall River Gas board or any committee thereof: (i) withdraws

<PAGE>

-    by Fall River Gas if:

     -   there is a breach of any representation, warranty, covenant or
         agreement of Southern Union, where the breach cannot be cured and
         would make Southern Union's representations and warranties materially
         inaccurate;

     -   (i) Fall River Gas gives Southern Union at least five business days'
         notice of its intent to enter into a definitive agreement with

         Fall River Gas merger agreement so that the parties can proceed with
         the merger and negotiate in good faith with Southern Union with
         respect to any such adjustments, and (ii) Fall River Gas has paid the

the merger agreement.

                         THE PROVENERGY MERGER AGREEMENT

This section is a summary of the material terms of the ProvEnergy merger
agreement, a copy of which is attached as Appendix C to this document. The
following description does not purport to be complete and is qualified in its
entirety by reference to the merger agreement. You should refer to the full
text of the ProvEnergy merger agreement for details of the ProvEnergy merger
and the terms and conditions of the ProvEnergy merger agreement.

STRUCTURE OF THE MERGER

On the closing date, GUS, a direct, wholly owned subsidiary of Southern Union,
will be merged into ProvEnergy in accordance with the laws of Rhode Island.
ProvEnergy will be the surviving corporation of this initial merger, which we
may refer to as the "surviving corporation."

Immediately after the initial merger, ProvEnergy will adopt an agreement and
plan of merger pursuant to which North Attleboro Gas, a wholly owned utility
subsidiary of ProvEnergy, will merge with and into ProvEnergy on the closing
date, with ProvEnergy being the surviving corporation, by complying with the
requirements of laws of Rhode Island and Massachusetts (the "Attleboro
Merger"). Immediately following the consummation of the Attleboro Merger,
ProvEnergy will adopt an agreement and plan of merger pursuant to which
Providence Gas, another wholly owned utility subsidiary of ProvEnergy, will
merge with and into ProvEnergy on the closing date with ProvEnergy being the
surviving corporation, by complying with the requirements of Rhode Island law
(the "ProvGas Merger"). Immediately following the consummation of the ProvGas
Merger, Southern Union will adopt an agreement and plan of merger pursuant to
which ProvEnergy will merge with and into Southern Union on the closing date,
with Southern Union being the surviving corporation, by complying with the
requirements of Rhode Island and Delaware law (the "final merger"). The
initial merger, the ProvGas Merger, the Attleboro Merger and the final merger,
collectively, are referred to in this proxy statement as the "ProvEnergy
merger."

Southern Union's existing charter and bylaws will remain in effect after the
ProvEnergy merger, and Southern Union's management and board of directors will
remain the same as a result of the ProvEnergy merger, except as otherwise
described in this proxy statement. See "Possible Effects of the Mergers on
Southern Union Stockholder Rights."

As a result of the ProvEnergy merger, ProvEnergy and its two utility
subsidiaries, Providence Gas and North Attleboro Gas, will become two
divisions of Southern Union with the operations of Providence Gas in one
division and the operations of North Attleboro Gas in the other division. The
non-regulated subsidiaries of ProvEnergy will become subsidiaries of Southern
Union.

CLOSING; EFFECTIVE TIME

On the closing date of the ProvEnergy merger, duly executed Articles of Merger
will be filed with the Secretary of State of Rhode Island complying with the
requirements of the Rhode Island Business Corporation Act. The initial merger
will become effective when the Secretary of State of Rhode Island issues a
Certificate of Merger. Immediately after the initial merger, Articles of
Merger for the Attleboro merger will be filed with the State Secretary of
Massachusetts and the Secretary of State of Rhode Island. After the
effectiveness of the Attleboro merger, Articles of Merger for the ProvGas
merger will be

filed with the Secretary of State of Rhode Island. Immediately after the
effectiveness of the ProvGas merger, Articles of Merger for the final merger
will be filed with the Secretary of State of Rhode Island and Delaware.

PROVENERGY MERGER CONSIDERATION

When the merger of GUS (Southern Union's acquisition subsidiary) into
ProvEnergy is completed, each share of ProvEnergy common stock will be
cancelled and ProvEnergy stockholders will receive $42.50 in cash for each
share of ProvEnergy common stock they own.

PROVIDENCE GAS PREFERRED STOCK

In accordance with the Certificate of Authorization for the 8.70% redeemable
cumulative preferred stock of Providence Gas, which we refer to as Providence
Gas preferred stock, ProvEnergy has caused Providence Gas to:

-    redeem 16,000 shares of its preferred stock on February 15, 2000 pursuant
     to its sinking fund, and

-    redeem 16,000 shares of its preferred stock on March 1, 2000.

No shares of ProvEnergy preferred stock remain outstanding after these
redemptions, as required by the ProvEnergy merger agreement.

PROVIDENCE GAS INDENTURE

ProvEnergy will cause Providence Gas to use its good faith commercially
reasonable efforts to obtain, prior to the effective time of the initial
merger, the consent of the holders of at least 80% in aggregate principal
amount of all First Mortgage Bonds outstanding under the First Mortgage of
Providence Gas, which we refer to as the Providence Gas Indenture, to each of
the amendments to the Providence Gas Indenture set forth on Schedule 6.1(n) to
the ProvEnergy merger agreement. ProvEnergy and its subsidiaries, however,
will not be required to make any payment to any bondholder prior to the
effective time of the initial merger.

If the ProvEnergy merger is not completed, Southern Union and ProvEnergy will
share equally the fees and expenses incurred in connection with obtaining
these consents. If the ProvEnergy merger agreement is terminated because one
party has breached its obligations under the merger agreement, the breaching
party will bear all of the fees and expenses incurred.

STOCK OPTIONS AND PERFORMANCE SHARES

Each ProvEnergy performance share awarded under a ProvEnergy incentive plan at
the effective time of the initial merger will be deemed fully earned and
converted into a right to receive $42.50 in cash.

In addition, each outstanding stock option will be deemed fully vested and
will be converted into a right to receive a cash payment for each share of
ProvEnergy common stock subject to option in an amount equal to the amount by
which $42.50 exceeds the exercise price of such option (if the exercise price
is less than $42.50).

COVENANTS AND OTHER AGREEMENTS, INCLUDING POST-CLOSING COMMITMENTS

ProvEnergy merger, except as otherwise permitted by the ProvEnergy merger

     business;

     business judgment and consistent with past practice and policy, and

     enter into any new contract for the supply, transportation, storage or

                                     55

<PAGE>

-    not amend its organizational documents; and

-    not issue or assume any note, debenture or other evidence of indebtedness,
     other than as specified under the ProvEnergy merger agreement.

The foregoing covenants are subject to certain specified exceptions, including
that Providence Gas may take any commercially reasonable action that
ProvEnergy determines in good faith, after consulting with Southern Union,
should be taken by Providence Gas in order to obtain the consent to the
proposed amendments to the Providence Gas Indenture.

Southern Union has consented to not restricting the ability of ProvEnergy to:

-    enter into any gas supply contract in the ordinary course of business,
     except if the term of the proposed contract is longer than three years, in
     which case ProvEnergy must consult in good faith with Southern Union, and

-    acquire non-regulated businesses, provided that the acquisitions are
     consistent with ProvEnergy's business plan and the purchase price of all
     acquisitions does not exceed $15,000,000 in the aggregate.

PROVENERGY SPECIAL MEETING; SOLICITATION OF PROXIES. Subject to the fiduciary
duties of the board of directors, ProvEnergy agreed to recommend to its
shareholders the approval of the ProvEnergy merger agreement and the
transactions contemplated thereby. On May 22, 2000, the stockholders of
ProvEnergy approved the terms of the ProvEnergy merger.

DIVIDENDS. ProvEnergy agreed that it will not declare any dividends on its
capital stock, or permit its subsidiaries to declare any dividend in capital
stock, other than quarterly dividends not to exceed $1.08 per share per fiscal
year on ProvEnergy's common stock and cumulative cash distributions on the
preferred stock of Providence Gas at an annual rate of $8.70 per share.

GOVERNMENTAL APPROVALS AND THIRD PARTY CONSENTS. ProvEnergy and Southern Union
each agreed to use its commercially reasonable best efforts at its sole
expense to obtain all necessary consents, approvals and waivers required in
connection with the transactions contemplated by the ProvEnergy merger
agreement.

EMPLOYEES; BENEFITS. Southern Union has agreed that following the effective
time of the initial merger it will assume and maintain for their respective
terms all employment and change in control agreements of ProvEnergy in effect
as of that time. In addition, simultaneously with the execution of the
ProvEnergy merger agreement, Southern Union entered into an employment
agreement with Mr. James Dodge and an amendment to the existing employment
agreement with Mr. James DeMetro, both of which will become effective as of
the effective time of the initial merger. See the summary of employment
agreements above under "The ProvEnergy Merger -- Interests of ProvEnergy
Officers and Directors in the ProvEnergy Merger".

Southern Union has agreed that, during the 24 month period immediately
following the closing date, it will:

-    maintain base salary levels, bonus opportunity levels and overall employee
     benefits, with specified exceptions, that are no less favorable in the
     aggregate than those currently provided,

-    maintain all qualified and non-qualified defined benefit pension plans
     without adverse amendment, except as may be required by law or to comply
     with tax qualification nondiscrimination rules, and

-    provide severance benefits on a basis no less favorable than would
     otherwise be provided to employees under the applicable ProvEnergy
     severance plan.

For the 24 months immediately following the above period, Southern Union has
agreed to maintain base salary levels, bonus opportunity levels and overall
employee benefits that are appropriate for the market given Southern Union's
financial circumstances, the industry in which it operates and regulatory
considerations.

Southern Union also agreed:

                                     56

<PAGE>

-    to recognize the tenure of employment of all employees with ProvEnergy and
     its subsidiaries for purposes of eligibility, vesting and accrual of
     benefits under all benefit plans to be provided by Southern Union,

-    to recognize employees' tenure of employment for purposes of awarding
     vacation time,

-    to allow each employee to carry forward all accrued sick leave,

-    to allow each employee who satisfies the eligibility criteria used by
     Southern Union for similarly situated employees to be immediately eligible
     for awards in the Southern Union Long-Term Incentive Stock Option Plan,
     and

-    to provide, for a period of 5 years from the closing date, retiree health
     benefits substantially comparable to coverage under the current ProvEnergy
     retiree medical plan to current retirees and their dependents and to
     active employees and their dependents who retire within 5 years of the
     closing and satisfy the plan's eligibility requirements.

Southern Union agreed that from the effective time of the initial merger until
the earlier of their resignation or removal by the President of Southern Union:

-    James H. Dodge will serve as Chief Executive Officer and President of the
     ProvEnergy and North Attleboro Gas divisions of Southern Union and all
     other energy-related businesses of Southern Union conducted in New
     England, and

-    James DeMetro will serve as Executive Vice President, Energy Services, of
     the ProvEnergy and North Attleboro Gas divisions of Southern Union and all
     other energy-related businesses of Southern Union conducted in New
     England.

Southern Union also agreed that specified individuals will serve the
ProvEnergy divisions of Southern Union from the effective time of the initial
merger until the earlier of their resignation or removal by Southern Union.
Currently, those individuals are listed below and will serve in the following
capacities:

-     Kenneth W. Hogan as Vice President, Chief Financial Officer and
        Treasurer,
-     Susann G. Mark as Vice President and General Counsel,
-     James A. Grasso as Vice President, Public Government Affairs,
-     Gerald A. Yurkevicz as Vice President, Business Development and
        Marketing,
-     Royalynne Hourihan as Vice President, Human Resources,
-     Timothy S. Lyons as Vice President, Marketing and Regulatory Affairs,
-     Robert W. Owens as Senior Vice President, Gas Distribution,
-     Peter J. Gill as Vice President, Information Technology,
-     James M. Stephens as President of Providence Energy Services, and
-     George Mason as Vice President of Providence Energy Oil.

CHARITABLE CONTRIBUTIONS. Southern Union agreed to continue making
ProvEnergy's annual charitable contributions for three years after the initial
merger in an aggregate amount of not less than $175,000 per year.

CORPORATE OFFICES.  For at least three years after the effective time of the
initial merger, Southern Union will:

-     operate ProvEnergy's operations in Rhode Island and Massachusetts as
      separate divisions of Southern Union,

-     maintain the principal executive offices of ProvEnergy in Rhode Island,
      and

-     maintain the principal executive offices of ProvEnergy as the
      principal executive offices of Southern Union's energy-related businesses
      conducted in New England; provided, however, that Southern Union will not
      be required to maintain these Rhode Island offices as the principal
      executive offices for all of Southern Union's energy-related businesses
      conducted in New England if Mr. James Dodge ceases to be the Chief
      Executive Officer of the ProvEnergy division of Southern Union.

                                     57

<PAGE>


INDEMNIFICATON AND INSURANCE FOR PROVENERGY OFFICERS AND DIRECTORS

Southern Union agreed for a period of six years after the effective time of
the ProvEnergy merger:

-    to indemnify and hold harmless the present and former officers and
     directors of ProvEnergy and its subsidiaries in respect of acts or
     omissions occurring prior to the effective time to the extent provided
     under ProvEnergy's articles of incorporation and bylaws, and

-    to use its reasonable best efforts to provide officers' and directors'
     liability insurance for acts and omissions occurring before the effective
     time on terms with respect to coverage and amount that are no less
     favorable than the terms in effect on the date of the ProvEnergy merger
     agreement, but if the annual premiums are more than 200% of the previous
     year's premiums paid by ProvEnergy, Southern Union must obtain a policy
     with best coverage available, in the reasonable judgment of the board of
     directors of Southern Union, for a cost not exceeding that amount.

See "The ProvEnergy Merger -- Interests of ProvEnergy Officers and Directors
in the ProvEnergy Merger."

NO SOLICITATION BY PROVENERGY

In the ProvEnergy merger agreement, ProvEnergy agreed that neither it, nor its
subsidiaries, nor any of its officers, directors, agents, financial advisors,
attorneys, accountants or other representatives will, directly or indirectly,

-    solicit, initiate or encourage the submission of proposals or offers from
     any person relating to, or that could reasonably be expected to lead to, a
     business combination,

-    participate in any negotiations or substantive discussions regarding any
     business combination,

-    furnish to any person any information with respect to a business
     combination, or

-    otherwise cooperate in any way with, or assist or participate in,
     facilitate or encourage, any effort or any attempt by any third party to do
     or seek a business combination.

Prior to the approval of the ProvEnergy merger agreement by ProvEnergy's
shareholders, which was obtained on May 22, 2000, ProvEnergy was permitted to,
in response to an unsolicited written proposal from a third party which the
board of directors determined, in its good faith judgment, after consultation
with and the receipt of the advice of its financial advisor and outside
counsel with customary qualifications, was a superior proposal,

-    furnish information to, negotiate, explore or otherwise engage in
     substantive discussions with such third party, provided ProvEnergy's board
     of directors determined, in its good faith judgment after consultation
     with its financial advisors and outside counsel, that it was reasonably
     necessary in order to comply with its fiduciary duties under applicable
     law, and

-    take and disclose to ProvEnergy's shareholders a position with respect to
     another business combination or make such disclosure to ProvEnergy
     shareholders which in the good faith judgment of Providence Energy's board
     of directors, based on advice of its outside counsel, was required by
     applicable law.

When we refer to a "superior proposal," we mean

-    a merger, consolidation, or other business combination, share exchange,
     sale of a minimum of 2% of the outstanding shares of capital stock, tender
     offer or exchange offer or similar transaction involving ProvEnergy or any
     of its subsidiaries,

-    an acquisition in any manner, directly or indirectly, of a material
     interest in any capital stock of, or a material equity interest in a
     substantial portion of the assets of ProvEnergy or any of its
     subsidiaries, or

-    the acquisition in any manner, directly or indirectly, of a material
     portion of the business or assets of ProvEnergy and its subsidiaries which
     involves at least 50% of the capital stock or a material portion of the
     assets of ProvEnergy and that

                                     58

<PAGE>

     -   ProvEnergy's board of directors determines, after consulting with
         ProvEnergy's financial advisors and outside counsel, is financially
         superior to the transactions contemplated by the ProvEnergy merger
         agreement, and

     -   it appears that the party making the proposal is reasonably likely to
         have the funds to complete the business combination.

In addition, ProvEnergy has agreed that before providing any non-public
information to any third party, or entering into negotiations with any third
party or accepting a superior proposal, ProvEnergy must:

-    provide written notice to Southern Union to the effect that it is
     furnishing information to or entering into discussions or negotiations
     with the third party, and

-    receive an executed confidentiality agreement from that third party
     containing substantially the same terms and conditions as the
     confidentiality agreement between ProvEnergy and Southern Union.

ProvEnergy has also agreed to terminate any existing solicitation, initiation,
encouragement, activity, discussion or negotiations with any parties conducted
before the date of the ProvEnergy merger agreement with respect to any
business combination.

CONDITIONS TO THE COMPLETION OF THE PROVENERGY MERGER

ProvEnergy and Southern Union may complete the ProvEnergy merger only if each
of the following conditions is met:

-    the holders of a majority of the shares of ProvEnergy common stock
     entitled to vote approve the ProvEnergy merger agreement, which approval
     was obtained on May 22, 2000,

-    all required governmental approvals are obtained by final order in such
     form as are not, and with no conditions that are, individually or in the
     aggregate, reasonably likely to have a ProvEnergy material adverse effect
     or a material adverse effect on the business, financial condition or
     results of operations of Southern Union, or which would otherwise, in
     Southern Union's reasonable determination, be unduly burdensome to
     Southern Union in a manner that would, individually or in the aggregate,
     be reasonably likely to have a ProvEnergy material adverse effect or a
     material adverse effect on the business, financial condition or results
     of operations of Southern Union.  Subsequent to the execution of the
     ProvEnergy merger agreement, the issue arose as to whether Southern Union
     was required under Massachusetts law to obtain the approval of the North
     Attleboro merger by holders of two-thirds of the outstanding shares of
     Southern Union common stock in connection with obtaining the approval of
     the North Attleboro merger by the MDTE.  In order to eliminate any
     uncertainty concerning this issue and to facilitate the closing of the
     transaction, Southern Union has advised ProvEnergy and the MDTE that it
     intends to seek such approval,

-    the holders of at least 80% in aggregate principal amount of all First
     Mortgage Bonds outstanding consent to each of amendments to the Providence
     Gas Indenture specified in the ProvEnergy merger agreement,

-    the necessary third party consents to the ProvEnergy merger agreement are
     obtained to the reasonable satisfaction of Southern Union, except for
     those which, if not obtained, are not, individually or in the aggregate,
     reasonably likely to result in a ProvEnergy material adverse effect after
     the closing,

-    ProvEnergy has caused the redemption of all of the outstanding shares of
     Providence Gas preferred stock in accordance with the organizational
     documents of Providence Gas, which redemption was completed on March 1,
     2000,

-    the waiting period applicable to the merger under the Hart-Scott-Rodino
     Antitrust Improvement Act of 1976 terminates or expires,

-    the representations and warranties of the other party in the ProvEnergy
     merger agreement are accurate in all respects as of the date of the
     ProvEnergy merger agreement and as of the closing date, except for such
     inaccuracies, without regard to any materiality qualifications, which,
     individually or in the aggregate, would not be reasonably likely to result
     in a material adverse effect,

                                     59

<PAGE>

-    the other party has performed or complied with its covenants, agreements
     and conditions under the ProvEnergy merger agreement in all material
     respects,

-    Letters of Tax Good Standing for ProvEnergy and Providence Gas are
     obtained from the Rhode Island Department of Taxation,

-    each party delivers an executed certificate of an authorized officer,
     dated the closing date, stating that all warranties and conditions have
     been satisfied,

-    there are no orders which operate to restrain, enjoin or otherwise
     prevent the completion of the ProvEnergy merger,

-    all directors who have options outstanding under the 1989 Non-Employee
     Director Stock Option Plan consent to the conversion of their options into
     a right to receive a cash payment as described above in "-- Stock Options
     and Performance Shares,"

-    each director of ProvEnergy and its subsidiaries, whose resignation is
     requested by Southern Union, will resign such directorship as of the
     closing date of the merger.

When we say "material adverse effect" above, we mean a material adverse effect

-    on the business, financial condition or results of operations of a party
     and its subsidiaries, taken as a whole, or

-    on the ability of a party and its subsidiaries to complete the ProvEnergy
     merger in accordance with the ProvEnergy merger agreement.

AMENDMENT OF THE PROVENERGY MERGER AGREEMENT

ProvEnergy and Southern Union may amend in writing the terms of the ProvEnergy
merger agreement before the closing.

TERMINATION OF THE PROVENERGY MERGER AGREEMENT

The ProvEnergy merger agreement can be terminated at any time prior to the
closing of the ProvEnergy merger under the conditions specified below.

-    Either party may terminate the ProvEnergy merger agreement at any time by
     mutual written consent.

-    Either party may also terminate the ProvEnergy merger agreement if:

     -   there is a non-appealable court order prohibiting the completion of
         the mergers in accordance with the ProvEnergy merger agreement,

     -   there is a breach by the other party of any representation or
         warranty, which breach cannot be cured, except for inaccuracies which
         would not be reasonably likely to result in a material adverse effect,

     -   the approval of ProvEnergy shareholders is not obtained, or

     -   the closing of the ProvEnergy merger does not occur before November
         15, 2000; provided, that if all conditions to closing have been
         fulfilled except for approvals by any governmental body, then this
         termination date will be extended until April 1, 2001.

-    ProvEnergy may terminate the ProvEnergy merger agreement if, prior to the
     special meeting, the board of directors has entered into a definitive
     agreement with respect to a business combination proposal; provided that:

     -   ProvEnergy responded to an unsolicited business combination proposal,

                                     60

<PAGE>

     -   the board of directors determines, in its good faith judgment, after
         consultation with and the receipt of advice from its financial advisor
         and outside legal counsel with customary qualifications, that the
         business combination proposal is a superior proposal and that failure
         to do so would create a reasonable possibility of a breach of the
         board's fiduciary duties,

     -   before terminating the ProvEnergy merger agreement, ProvEnergy
         complies with specified notice and waiting periods, which give
         Southern Union an opportunity to negotiate with ProvEnergy to adjust
         the terms of the ProvEnergy merger agreement, and

     -   ProvEnergy has paid Southern Union the $7.5 million termination fee
         described below under "--Termination Fees and Expenses."

-    Southern Union may terminate the ProvEnergy merger agreement if:

     -   the board of directors of ProvEnergy:

         (i)      withdraws or modifies, or proposes publicly to withdraw or
                  modify, in a manner adverse to Southern Union, the approval
                  or recommendation of the board in favor of the ProvEnergy
                  merger agreement,

         (ii)     approves or recommends, or proposes publicly to approve
                  or recommend, a business combination with a third party,

         (iii)    causes ProvEnergy to enter into a definitive agreement
                  related to any business combination, or

         (iv)     resolves to take any of the actions specified above, or

     -   if a third party or group acquires more than 50% of the voting power
         of the outstanding voting securities of ProvEnergy, or

     -   if ProvEnergy had failed to cause the redemption of all of the
         outstanding shares of Providence Gas preferred stock.

TERMINATION FEES AND EXPENSES

The ProvEnergy merger agreement obligates ProvEnergy to pay Southern Union a
termination fee of $7.5 million in cash if:

-    ProvEnergy terminates the ProvEnergy merger agreement because it has
     entered into a definitive agreement resulting from a superior proposal, as
     described in the third bullet point above under "-- Termination of the
     ProvEnergy Merger Agreement," or

-    Southern Union terminates the ProvEnergy merger agreement for the reasons
     specified in the last bullet point above under "-- Termination of the
     ProvEnergy Merger Agreement."

The ProvEnergy merger agreement provides that each of the parties will pay all
costs and expenses incurred in connection with its performance of and
compliance with the merger agreement, except as expressly contemplated by the
merger agreement.

In addition, the ProvEnergy merger agreement specifies that Southern Union
will pay all real estate transfer taxes and real estate recording fees, if
any, including expenses of counsel associated with real estate title, transfer
and recording issues in connection with the ProvEnergy merger and all filing
and application fees paid to governmental bodies in connection with the
merger. ProvEnergy will pay the costs of printing and mailing its proxy
statement to ProvEnergy shareholders.

                       POSSIBLE EFFECTS OF THE MERGERS ON
                        SOUTHERN UNION STOCKHOLDER RIGHTS

Southern Union is a Delaware corporation. The rights of a holder of Southern
Union common stock are presently governed by Southern Union's restated
certificate of incorporation and bylaws and the Delaware General Corporation
Law ("DGCL").

Fall River Gas and North Attleboro Gas, a utility subsidiary of ProvEnergy,
are Massachusetts corporations. Chapter 164 of the Massachusetts General Laws
("MGL, Chapter 164") provides that the rights of stockholders of Massachusetts
gas utility companies, which Southern Union may be deemed to be because of the
mergers, are also governed by certain provisions of MGL, Chapter 164, as well
as certain provisions of MGL, Chapter 156B (Massachusetts' general business
corporation statute).

Even though Southern Union will continue to exist as a Delaware corporation
following the mergers and Southern Union's restated certificate of
incorporation and bylaws will survive rather than those of Fall River Gas or
North Attleboro Gas, there are certain areas where the provisions of MGL,
Chapter 164, differ from those of the DGCL with respect to certain corporate
governance matters, including, more specifically, with regard to requirements
for stockholder approval in certain instances. While Southern Union believes
that following the merger, the provisions of the DGCL should take precedence
with regard to these areas where differences exist, it is uncertain whether in
any or all of these instances, the corporate affairs, including the rights of
stockholders to vote on certain matters, of the combined company may be
subject to some or all of the corporate governance provisions of MGL, Chapter
164, which are applicable to Massachusetts gas utility companies subject to
that Chapter. Neither the MDTE, which regulates Massachusetts gas distribution
companies, nor the Courts of the Commonwealth of Massachusetts, have
determined whether under MGL, Chapter 164, a utility that distributes gas to
customers within Massachusetts but is not incorporated under Massachusetts law
is subject to all or any portions of MGL, Chapter 164's corporate governance
provisions that would otherwise pertain to a gas distribution company
incorporated domestically in Massachusetts. Following the mergers, Southern
Union intends to work with its legal advisors and Massachusetts regulatory
authorities to address and resolve any uncertainties if and as they arise, and
may, if necessary, work with others to obtain legislative relief or
clarification.

The provisions of the MGL, Chapter 164, that could be applicable to Southern
Union after the Fall River Gas and North Attleboro Gas mergers are in relation
to Southern Union stockholder rights as follows:

A merger of, consolidation of, or sale or purchase of all or substantially all
corporate properties involving companies, one or both of which are subject to
MGL, Chapter 164 by virtue of conducting utility operations in the State of
Massachusetts must be approved by each such company by at least two-thirds of
the shares entitled to vote thereon. Presently, under Delaware law and
Southern Union's Certificate of Incorporation such a transaction in which
Southern Union is the surviving entity would not require stockholder approval,
other than majority stockholder approval for a merger that results in the
issuance by Southern Union of shares of common stock pursuant to the plan of
merger or upon the conversion of securities of the merging entity that exceed
20% of the shares of Southern Union common stock outstanding prior to the
merger; or a sale or other disposition by Southern Union of all or
substantially all of its assets. Since these provisions would not likely
affect Southern Union's ability to make acquisitions outside Massachusetts in
which Southern Union is the surviving entity, Southern Union does not believe
this provision will adversely affect its growth strategy. To the extent that
this provision might increase the vote of Southern Union stockholders required
for another company to acquire Southern Union, this provision could deter
third parties' interest in proposing to acquire Southern Union. The proposal
to merge with Fall River Gas and ProvEnergy has been prompted by business and
financial considerations and not by the threat of any hostile takeover attempt
(nor is the Southern Union board of directors currently aware of any such
attempts directed at Southern Union), but, stockholders should be aware that
approval of the proposal could facilitate future efforts, if any, by Southern
Union to deter or prevent changes in control of the company, including
transactions in which the stockholders might otherwise receive a premium for
their shares over the then-current market prices.

A gas company or other corporation subject to the MGL, Chapter 164, may enter
into a mortgage of, or issue a bond in which a lien is placed on, all or
substantially all of the assets of the company essentially only with the
approval by a vote of a majority of its stockholders entitled to vote thereon.
Presently, Southern Union's board has the discretion to take the foregoing
actions without stockholder approval.

Directors of gas companies subject to MGL, Chapter 164, Section 4, who vote
for, and officers who knowingly participate in, any loan of any assets of a
company to any of its officers or directors are jointly and severally liable
for any portion of the loan which is not repaid. This provision does not apply
if the loan is approved or ratified as a loan which is reasonably expected to
benefit the company by either a majority of the directors who are not direct
or indirect recipients of the loan, or by stockholders who are not direct or
indirect recipients of the loan and hold a majority of the shares entitled to
vote for directors. Under Delaware law, a contract or transaction between a
corporation and an interested director or officer is not void or voidable if
(i) either the interest of the officer or the director was disclosed at the
time it was approved or the contract or transaction is fair to the
corporation, and (ii) the contract or transaction is approved by a majority of
the disinterested

                                     62

<PAGE>

board of directors, a committee of the board comprised of disinterested
directors or a vote of the stockholders. Delaware law does not state that
directors who vote for, or officers who participate in, a loan of corporate
assets to a director or officer are personally liable for any portion of the
loan that is not repaid, although this result could occur if such director or
officer was proven to have breached his duty of loyalty through his actions in
approving such transaction.

This summary does not purport to be a complete discussion of, and is qualified
in its entirety by reference to, the DGCL and the MGL, as well as the restated
certificate of incorporation and bylaws of Southern Union.

In addition, a company operating as a utility in either Massachusetts or Rhode
Island cannot issue a stock dividend without approval from the MDTE or the
RIDPUC, whichever is applicable. Because we have a policy of declaring and
distributing an annual 5% stock dividend, we intend to seek approval for our
dividend policy from both of these agencies after the mergers are completed.
We will seek such approvals before we declare and distribute the first such
anticipated dividend after the anticipated closing of the pending mergers,
which would be the 2001 stock dividend.

           UNAUDITED PRO FORMA COMBINED CONDENSED FINANCIAL STATEMENTS

The following Unaudited Pro Forma Combined Condensed Financial Statements
present the combined financial data of Southern Union, PEI, Fall River Gas,
ProvEnergy and Valley Resources, including their respective subsidiaries,
after giving effect to Southern Union's merger with each of them. The PEI
merger, completed on November 4, 1999, was, and the Fall River Gas, ProvEnergy
and Valley Resources mergers will be, accounted for as a purchase. The
Unaudited Pro Forma Combined Condensed Financial Statements also give effect
to Southern Union's issuance of $300 million of senior notes that was
completed on November 3, 1999, in anticipation of the PEI merger, prospective
financing for the pending acquisitions by merger of Fall River Gas, ProvEnergy
and Valley Resources, and the assumption of certain debt of the acquired
companies.

The Unaudited Pro Forma Combined Condensed Balance Sheet as of March 31, 2000,
gives effect to the previously identified acquisitions and financing
transactions as if they had occurred on that date. The Unaudited Pro Forma
Combined Condensed Statements of Operations for the year ended June 30, 1999,
and the nine months ended March 31, 2000, give effect to the previously
identified acquisitions and financing transactions as if they had occurred on
July 1, 1998, and July 1, 1999, respectively, which are the beginning dates
for such periods.

The fiscal year of Southern Union ends on June 30. The fiscal year of PEI
ended on December 31. The fiscal years of Fall River Gas and ProvEnergy end on
September 30. The fiscal year of Valley Resources ends on August 31.
Accordingly, the Unaudited Pro Forma Combined Condensed Balance Sheet as of
March 31, 2000, is derived from the March 31, 2000, balance sheets for each of
Southern Union, Fall River Gas and ProvEnergy, and the February 29, 2000,
balance sheet of Valley Resources. Also, the Unaudited Pro Forma Combined
Condensed Statements of Operations for the year ended June 30, 1999, and the
nine months ended March 31, 2000, have been prepared using comparable
financial statement periods of PEI, Fall River Gas and ProvEnergy, and the
results of operations for the twelve-month period ended May 31, 1999 and the
nine-month period ended February 29, 2000 of Valley Resources. The foregoing
financial statements have all been incorporated by reference to previous
filings with the SEC made by Southern Union or such other company. The
following Unaudited Pro Forma Combined Condensed Financial Statements have
been prepared from, and should be read in conjunction with, those historical
financial statements and related notes thereto of Southern Union, PEI, Fall
River Gas, ProvEnergy and Valley Resources. See "Where You Can Find More
Information."

The historical financial statements of the acquired companies that appear in
or were used for the Unaudited Pro Forma Combined Condensed Financial
Statements include or required certain reclassifications to conform to
Southern Union's presentation. These reclassifications have no impact on net
income or total stockholders' equity.

The pro forma adjustments reflect an estimated additional purchase cost
assigned to utility plant based on the historical cost of the regulated assets
and liabilities of the acquired companies and an estimate of the fair value of
the non-regulated assets and liabilities of the acquired companies, plus
estimated acquisition costs for the pending transactions. The estimate of the
fair value of the non-regulated assets are preliminary and may be revised to
reflect independent appraisals, which have not been completed.

The Unaudited Pro Forma Combined Condensed Financial Statements are based on
the assumption that upon completion of the Fall River Gas merger each Fall
River Gas stockholder will receive, in exchange for each share of Fall River
Gas common stock he or she owns, a combination of Southern Union common stock
and/or cash worth in the aggregate $23.50; the cash consideration is limited
to 50% of the aggregate consideration paid to all Fall River Gas stockholders.
The following pro forma adjustments reflect a payment of 50% cash and 50%
Southern Union common stock for each share of Fall River Gas common stock.

The following Unaudited Pro Forma Combined Condensed Financial Statements are
presented in accordance with the assumptions set forth below for purposes of
illustration only and are not necessarily indicative of the financial position
or operating results that would have occurred if the previously identified
acquisitions and financing transactions had been consummated on the date as of
which, or at the beginning of the periods for which, they are being given
effect nor are they necessarily indicative of the future operating results or
financial position of the combined enterprise. The Unaudited Pro Forma
Combined Condensed Financial Statements do not contain any adjustments to
reflect cost savings or other synergies anticipated as a result of the
mergers. The weighted average shares of common stock and common stock
equivalents outstanding have been adjusted for the 5% stock dividend
distributed on June 30, 2000. Operating results for the nine months ended
March 31, 2000 are not necessarily indicative of the results that may be
expected for the entire fiscal year ending June 30, 2000.

       NOTES TO UNAUDITED PRO FORMA COMBINED CONDENSED FINANCIAL STATEMENTS



ADJUSTMENTS TO THE UNAUDITED PRO FORMA COMBINED CONDENSED BALANCE
SHEET

(A)   Reflects the estimated excess of the purchase price and other transaction
      costs over the historical cost of the regulated net assets and the
      estimated fair value of the non-regulated net assets of Fall River Gas,
      ProvEnergy, and Valley Resources, collectively "the pending
      acquisitions."

(B)   Reflects excess cash after application of the net proceeds from the
      merger financing of the pending acquisitions. See Note (F).

(C)   Reflects the capitalization of estimated costs associated with the bank
      borrowings as more specifically described in Note (F) to be incurred in
      connection with the pending acquisitions. These financing costs are
      amortized on a straight-line basis over the life of the bank borrowings.

(D)   Reflects the elimination of common stockholders' equity of Fall River
      Gas, ProvEnergy, and Valley Resources.

(E)   Reflects the issuance of Southern Union common stock to Fall River Gas
      stockholders. See Notes (L) and (N).

(F)   Reflects bank borrowings at an estimated annual interest rate of 7.60%,
      which Southern Union believes would be obtained based on current market
      rates.  The bank borrowings are assumed to be utilized: to finance the
      cash portion of the purchase of Fall River Gas, ProvEnergy, and Valley
      Resources  and the settlement of any respective stock options; and to pay
      various professional fees and change of control agreements expected to be
      incurred in connection with the pending acquisitions estimated to total
      $9 million.  See Notes (H) and (M).

ADJUSTMENTS TO THE UNAUDITED PRO FORMA COMBINED CONDENSED STATEMENTS OF
OPERATIONS

(G)   Reflects amortization of the estimated excess purchase price over the
      historical cost of the regulated net assets and the estimated fair value
      of the non-regulated net assets of PEI, Fall River Gas, ProvEnergy, and
      Valley Resources on a straight-line basis over a 40-year period based on
      the estimated useful lives of these assets.  The pro forma adjustment
      for the nine-month period ended March 31, 2000 reflects only four months
      of amortization of additional purchase cost related to the acquisition
      of PEI,  as five months of actual are included in Southern Union's
      historical balances due to the closing of this merger on November 4,
      1999.

(H)   Reflects interest expense on bank borrowings for the pending acquisitions
      at an estimated annual interest rate of 7.60%, which Southern Union
      believes would be obtained based on current market rates, and interest
      expense on the $300 million of long-term debt at 8.25% issued on November
      3, 1999 in connection with the PEI merger. The bank borrowings and long-
      term debt are assumed to be utilized: to finance the cash portion of the
      purchase of PEI, Fall River Gas, ProvEnergy and Valley Resources and the
      settlement of any respective stock options; to refinance certain debt of
      PEI and Southern Union; to fund PEI's Director Retirement Plan, Director
      Deferred Compensation Plan and supplemental retirement benefits and the
      payments for severance benefits for certain PEI executives; and to pay
      various professional fees and change of control agreements expected to
      be incurred in connection with all mergers estimated to total $12
      million. For every 1/8 percent change in the interest rate assumed for
      the bank borrowings, expense for the 12-month period would change by
      approximately $550,000. The rate on the $300 million issued for PEI is
      fixed at 8.25%, so no variation in the rate for this long-term debt was
      calculated.

(I)   Reflects the elimination of historical interest expense of PEI as a
      result of refinancing certain debt in connection with the PEI merger. See
      Notes (H) and (M).

(J)   Reflects the income tax consequences at the federal statutory rate of the
      pro forma adjustments after excluding nondeductible goodwill
      amortization.

(K)   Reflects the elimination of preferred stock dividend requirement due to
      the repurchase of all outstanding PEI and ProvEnergy preferred stock
      prior to the closing of the mergers for PEI and ProvEnergy.

(L)   Reflects the issuance of 16,713,735 pre-stock dividend shares of Southern
      Union stock for the purchase of PEI. Also reflects the estimated issuance
      of 1,541,867 shares of Southern Union stock for the purchase of Fall
      River Gas, based on an average trading price of $15.7954 for the ten
      trading-day period ending on the third trading day before June 30, 2000
      and an exchange ratio of 1.39259. The actual exchange ratio for the Fall
      River Gas merger will be based upon the average closing price per share
      for Southern Union common stock for the ten trading day period ending on
      the third full trading day the day the merger is completed. The exchange
      ratio will not be lower than 1.19365 nor greater than 1.39259. Due to
      the loss position resulting from the pro forma adjustments, the diluted
      shares outstanding were adjusted for 1,779,747 shares of common stock
      equivalents that had been included in Southern Union's historical
      amounts.

(M)   Reflects interest expense on bank borrowings for the pending acquisitions
      at an estimated annual interest rate of 7.60%, which Southern Union
      believes would be obtained based on current market rates, and interest
      expense on the $300 million of long-term debt at 8.25% issued on November
      3, 1999 in connection with the PEI merger. The non-PEI merger-related
      long-term debt is assumed to be utilized: to finance the cash portion of
      the purchase of Fall River Gas, ProvEnergy, and Valley Resources; and the
      settlement of any respective stock options; and to pay various
      professional fees and change of control agreements incurred in connection
      with the three pending mergers estimated to total $9 million. The pro
      forma adjustment for the nine-month period ended March 31, 2000 reflects
      only four months of interest expense related to the $300 million of
      long-term debt issued for the acquisition of PEI, as five months of
      actual are included in Southern Union's historical balances due to the
      closing of this merger on November 4, 1999. For every 1/8 percent change
      in the interest rate assumed for the bank borrowings, expense for the
      nine-month period would change by approximately $400,000. The rate on
      the $300 million issued for PEI is fixed at 8.25%, so no variation in
      the rate for this long-term debt was calculated.

(N)   Reflects the issuance of 16,713,735 pre-stock dividend shares of Southern
      Union stock for the purchase of PEI. Also reflects the estimated issuance
      of 1,541,867 shares of Southern Union stock for the purchase of Fall
      River Gas, based on an average trading price of $15.7954 for the ten
      trading-day period ending on the third trading day before June 30, 2000
      and an exchange ratio of 1.39259. The actual exchange ratio for the Fall
      River Gas merger will be based upon the average closing price per share

      the third full trading day prior to the day the merger is completed. The
      exchange ratio will not be lower than 1.19365 nor greater than 1.39259.
      Due to the loss position resulting from the pro forma adjustments, the
      diluted shares outstanding were adjusted for 2,044,899 shares of common
      stock equivalents that had been included in Southern Union's historical
      amounts.

                             SOUTHERN UNION COMPANY

The following briefly describes the business of Southern Union. Additional
information regarding Southern Union is contained in its filings with the SEC
pursuant to the Securities Exchange Act of 1934. See "Where You Can Find More
Information" on page 4.

GENERAL

Southern Union was incorporated under the laws of the State of Delaware in
1932 and is one of the fifteen largest gas utilities in the United States, as
measured by number of customers. Southern Union's principal line of business
is the distribution of natural gas as a public utility through Southern Union
Gas, Missouri Gas Energy ("MGE"), PG Energy and Atlantic Utilities, doing
business as South Florida Natural Gas ("SFNG"), each of which is a division of
Southern Union.

Southern Union Gas, headquartered in Austin, Texas, serves approximately
523,000 customers in Texas (including the cities of Austin, El Paso,
Brownsville, Galveston, Harlingen, McAllen and Port Arthur). MGE,
headquartered in Kansas City, Missouri, serves approximately 491,000 customers
in central and western Missouri (including the cities of Kansas City, St.
Joseph, Joplin and Monett). PG Energy, headquartered in Wilkes-Barre,
Pennsylvania, serves approximately 154,000 customers in northeastern and
central Pennsylvania (including the cities of Wilkes-Barre, Scranton and
Williamsport). SFNG, headquartered in New Smyrna Beach, Florida, serves
approximately 5,000 customers in central Florida (including the cities of New
Smyrna Beach and Edgewater and areas of Volusia County, Florida). The diverse
geographic area of Southern Union's natural gas distribution systems reduces
the sensitivity of Southern Union's operations to weather risk and local
economic conditions.

Subsidiaries of Southern Union have been established to support and expand
natural gas and other energy sales and to capitalize on Southern Union's
energy expertise. These subsidiaries market natural gas and electricity to end
users, operate natural gas pipeline systems, generate electricity, distribute
propane, and sell commercial gas air conditioning and other gas-fired
engine-driven applications. By providing "one-stop shopping," Southern Union
can serve its various customers' specific energy needs, which encompass
substantially all of the natural gas distribution and sales businesses from
natural gas sales to specialized energy consulting services. Southern Union
distributes propane to 11,000, 1,800 and 1,100 customers in Texas,
Pennsylvania and Florida, respectively. Through PG Energy Services, Inc.,
Southern Union markets electricity and other products and services under the
name PG Energy Power Plus, principally in northeastern and central
Pennsylvania. Through PEI Power Corporation, an exempt wholesale generator
(within the meaning of the Public Utility Holding Company Act of 1935),
Southern Union generates and sells electricity in northeastern and central
Pennsylvania. Through Keystone Pipeline Services, Inc. (a wholly owned
subsidiary of PG Energy Services, Inc.), Southern Union is engaged primarily
in the construction, maintenance and rehabilitation of natural gas
distribution pipelines.  Additionally, certain subsidiaries own or hold
interests in real estate and other assets.

Southern Union is a sales and market-driven energy company, whose management
is committed to achieving profitable growth of its utility businesses in an
increasingly competitive business environment. Southern Union's strategies for
achieving these objectives reflect Southern Union's commitment to its core gas
utility business.

ACQUISITIONS

Southern Union has a goal of selected growth and expansion, primarily in the
utilities industry. To that extent, Southern Union intends to consider, when
appropriate, and if financially practicable to pursue, the acquisition of
other utility distribution or transmission businesses. The nature and location
of any such properties, the structure of any such acquisitions and the method
of financing any such expansion or growth will be determined by Southern
Union's management and the Southern Union board of directors. These
acquisitions, including the proposed mergers with Fall River Gas and
ProvEnergy, require substantial additional financing through future debt, and
possibly future equity offerings. The availability and terms of any such
financing sources will depend upon various factors and conditions, such as
Southern Union's cash flow and earnings, its resulting capital structure,
credit ratings and conditions in financial capital markets at the time of any
such offering. In addition to the Fall River Gas and ProvEnergy mergers that
are the subject of the Southern Union Special Meeting and this proxy
statement, Southern Union has recently completed or agreed to two other
significant mergers that are summarized below.

                                     74

<PAGE>

MERGER WITH PEI

Effective November 4, 1999, Southern Union acquired PEI and its subsidiaries
for approximately 17 million shares of Southern Union common stock and
approximately $36 million in cash plus the assumption of approximately $150
million in debt. PEI's natural gas utility businesses are being operated as PG
Energy, a division of Southern Union, which provides service to approximately
154,000 natural gas customers in northeastern and central Pennsylvania
(including the cities of Wilkes-Barre, Scranton and Williamsport). Through the
acquisition of PEI, Southern Union acquired and now operates a subsidiary that
markets electricity and other products and services under the name PG Energy
Power Plus, principally in northeastern and central Pennsylvania. Other
subsidiaries that Southern Union acquired in the PEI merger engage in various
non-regulated activities, including the construction, maintenance and
rehabilitation of natural gas distribution pipelines.

PENDING MERGER WITH VALLEY RESOURCES

On November 30, 1999, Southern Union, SUG Acquisition Corporation, a Rhode
Island corporation and a wholly-owned subsidiary of Southern Union, and Valley
Resources (AMEX: VR) entered into a definitive merger agreement. The agreement
calls for Valley Resources to merge into Southern Union in a transaction
valued at approximately $160 million, including the assumption of debt. Valley
Resources shareholders will receive $25.00 in cash for each of the
approximately 4.98 million shares of Valley Resources common stock
outstanding. Valley Resources principally provides natural gas utility service
to more than 64,000 customers through its subsidiaries, Valley Gas Company and
Bristol & Warren Gas Company, in the Blackstone Valley Region located in
northeastern and eastern Rhode Island. Southern Union anticipates completing
the Valley Resources merger in September 2000 after all remaining conditions
are satisfied, including receipt of all regulatory approvals for the Valley
Resources merger. Valley Resources stockholders approved the Valley Resources
merger at their special meeting on June 13, 2000.

                                 FALL RIVER GAS

The following briefly describes the business of Fall River Gas. Additional
information regarding Fall River Gas is contained in its filing with the SEC.
See "Where You Can Find More Information" on page 4.

GENERAL

Fall River Gas was organized as a Massachusetts corporation on September 25,
1880 and is an investor-owned public utility company that sells, distributes
and transports natural gas (mixed with propane and liquefied natural gas
during winter months) at retail through a pipeline distribution system
throughout its 50 square mile service territory in the City of Fall River and
the towns of Somerset, Swansea and Westport, all located within the
southeastern portion of the Commonwealth of Massachusetts. This area has a
population of approximately 140,000. The principal markets served by Fall
River Gas are (1) residential customers using gas for heating, cooking and
water heating, (2) industrial customers using gas for processing items such as
textile and metal goods, (3) commercial customers using gas for cooking and
heating, and (4) federal and state housing projects using gas for heating,
cooking and water heating.

Fall River Gas is engaged in only one line of business as described above, and
in activities incidental to this business. Fall River Gas has one wholly-owned
subsidiary, Fall River Gas Appliance Company, Inc. (the "Appliance Company"),
a Massachusetts corporation, which rents water heaters and conversion burners
(primarily for residential use) in Fall River Gas' gas service area. Earnings
from the Appliance Company are primarily the result of revenues from the
rental of water heaters and conversion burners. The Appliance Company also
derives revenues from the sale of central heating and air-conditioning systems
and water heaters.

Fall River Gas' distribution system consist of approximately 635 miles of gas
mains ranging in size from 2 to 36 inches in diameter, approximately 29,000
services and approximately 50,000 active gas meters, together with related
facilities and equipment. In the preceding sentence, a "service" means a pipe
connecting a gas main with piping to a customer's premises. The gas utility
subsidiaries have regulating and metering facilities at 3 points of delivery
from Algonquin Gas Transmission Company. Fall River Gas presently believes
that these regulating and metering facilities are adequate for receiving gas
into their distribution systems from the interstate gas pipeline.

                                     75
<PAGE>

As of May 1, 2000, Fall River Gas provided service to approximately 48,000
natural gas customers.

Fall River Gas and its subsidiary employed approximately 175 persons as of May
1, 2000.

                                   PROVENERGY

The following briefly describes the business of ProvEnergy. Additional
information regarding ProvEnergy is contained in its filings with the SEC. See
"Where You Can Find More Information" on page 4.

REGULATED BUSINESSES

ProvEnergy is the parent of two wholly owned natural gas distribution
utilities, Providence Gas and North Attleboro Gas, which we refer to
collectively as the gas utility subsidiaries. Providence Gas, founded in 1847,
is Rhode Island's largest natural gas distributor and serves approximately
168,000 customers in Providence, Newport and 23 other cities and towns in
Rhode Island. North Attleboro Gas serves approximately 6,000 customers in
North Attleboro and Plainville, Massachusetts, towns adjacent to the
northeastern Rhode Island border. The total natural gas service territory of
the gas companies encompasses 760 square miles and has a population of
approximately 850,000.

NON-REGULATED BUSINESSES

ProvEnergy is also the parent of ProvEnergy Oil Enterprises, Inc., which
operates an oil distribution business through its subsidiary, ProvEnergy
Fuels, Inc. ("ProvEnergy Fuels"). ProvEnergy Fuels operates this business
under several trade names, which were among the assets of oil distribution
businesses acquired by ProvEnergy Fuels during the past three years, namely,
Super Service Oil (acquired in 1997), Keenan Oil (acquired in 1999) and
Consumers Oil (acquired in January, 2000). These acquisitions, as well as five
smaller acquisitions completed between 1997 and 1999, are part of ProvEnergy's
strategic plan to strengthen its position in the energy industry. Currently,
the oil business serves over 14,000 residential and commercial customers in
Rhode Island and Massachusetts.

ProvEnergy uses its wholly owned subsidiary, Providence Energy Services, Inc.,
to market natural gas and energy services to and as the vehicle to grow its
natural gas, oil, and electricity businesses with retail accounts in New
England.

Also, in July 1998, ProvEnergy and ERI Services, Inc. formed a joint venture,
Capital Center Energy Company, LLC., which is owned 50 percent by ProvEnergy's
subsidiary, ProvEnergy Power Company, LLC, and 50 percent by ERI Services'
subsidiary, ERI Providence, LLC. A wholly owned subsidiary of Capital Center
Energy Company, LLC, DownCity Energy Company, LLC, was selected as the
exclusive electric, heat and air conditioning and related service provider for
most of the Providence Place Mall for the next thirty years.

OPERATIONS OF PROVENERGY'S GAS UTILITY SUBSIDIARIES

CUSTOMERS

The gas utility subsidiaries have approximately 174,000 customers, of which
approximately 90% are residential and 10% are commercial and industrial.

GAS SERVICE

The gas services provided by the gas utility subsidiaries can be grouped into
four categories: firm sales, firm transportation, non-firm sales and non-firm
transportation. Firm service is provided to those residential, commercial and
industrial customers that use natural gas throughout the year. Non-firm
service is provided to those commercial and industrial customers that do not
require assured gas service because they can utilize an alternative fuel or
otherwise operate without gas service. The transportation service of the gas
utility subsidiaries transports to some customers gas owned by those customers
or by third parties selling gas to those customers.

Firm Sales. In the recent year, the gas utility subsidiaries distributed
approximately 57% of firm sales to residential customers and 43% of firm sales
to commercial and industrial customers. Firm sales represent the highest
percentage of operating margin and represent the core of the gas utility
subsidiaries' business.

                                     76
<PAGE>

Non-Firm. Non-firm customers consist of two types: seasonal customers that
typically use gas only during the non-winter months and dual-fuel customers
that contract for gas service on a year round basis, but agree to service
interruption during certain peak periods. By retaining the right to interrupt
service to non-firm customers, the gas utility subsidiaries can balance daily
demand from firm customers with available gas supply and pipeline capacity.
Non-firm customers may interrupt their gas service, as well, when it is more
economical to utilize an alternative fuel. Accordingly, the amount of the gas
utility subsidiaries' non-firm sales fluctuates depending upon the relative
price of natural gas to alternative fuels.

Non-firm sales produce substantially less margin to the gas utility
subsidiaries than firm sales as a result of the more competitive nature of
non-firm sales. Service rates charged to dual-fuel customers are based on the
price that the customer would otherwise pay for its alternative fuel.

Transportation Service. ProvEnergy provides both firm and non-firm
transportation of gas. Margin from the firm transportation of gas by certain
large customers is likely to represent an increasing percentage of the gas
utility subsidiaries' future total margin as a result of the continuing
developments affecting the natural gas industry. In general, these
developments now allow customers to buy gas directly from the
producer-supplier rather than solely from the local gas distribution company.
Customer-owned gas is transported to the customer's premises through a
combination of interstate pipelines and the gas utility subsidiaries'
distribution systems.

For a given quantity of gas, the gas utility subsidiaries' margin from firm
transportation service is comparable to the margin from firm sales. Margin
from non-firm transportation service is less than the margin from firm sales,
but is generally comparable to the margin from interruptible sales, depending
on the price of alternative fuels. To the extent that the gas utility
subsidiaries' existing customers buy gas directly from producer-suppliers, the
gas utility subsidiaries' revenue will decrease, although firm margin will not
be materially impacted.

GAS DISTRIBUTION SYSTEMS

ProvEnergy's gas utility subsidiaries' distribution systems consist of
approximately 2,400 miles of gas mains ranging in size from 2 to 36 inches in
diameter, approximately 146,000 services and approximately 173,000 active gas
meters, together with related facilities and equipment. In the preceding
sentence, a "service" means a pipe connecting a gas main with piping to a
customer's premises. The gas utility subsidiaries have regulating and metering
facilities at nine points of delivery from Algonquin Gas Transmission Company
and one point of delivery from Tennessee Gas Pipeline Company. The gas utility
subsidiaries presently believe that these regulating and metering facilities
are adequate for receiving gas into their distribution systems from these
interstate gas pipelines.

EMPLOYEES

ProvEnergy has approximately 643 full-time employees. Approximately 271 of

Restated Certificate of Incorporation of SUG, as in effect immediately prior
to the Effective Time, shall be the Certificate of Incorporation of the

                                   ARTICLE III

                              CONVERSION OF SHARES


SECTION 3.1 EFFECT OF THE MERGER. As of the Effective Time, by virtue of the
Merger and without any action on the part of the holders of any shares of FAL
Common Stock:

    (a) Each issued and outstanding share of FAL Common Stock (other than
        Dissenting Shares) will be converted into the right of each holder
        thereof to receive (i) that number of fully paid and nonassessable
        shares of SUG Common Stock (the "Stock Consideration") equal to $23.50
        divided by the Exchange Ratio rounded to the nearest hundred-thousandth
        or (ii) upon a valid Cash Election as provided in Section 3.1(b),
        $23.50 in cash (the "Cash Consideration"), subject to the limitations
        set forth in Section 3.1(b), 3.1(c), and 3.1(e). In the case of the
        consideration to be received by the holders of FAL Common Stock in the
        aggregate, "Merger Consideration" shall mean the Cash Consideration
        together with the Stock Consideration. In the case of the consideration
        to be received by an individual holder of FAL Common Stock, "Merger
        Consideration" shall mean the Cash Consideration and/or the Stock
        Consideration to be received by such holder, as the case may be.

"Exchange Ratio" shall mean the Average Trading Price of SUG Common Stock as
of the Closing Date. Notwithstanding the foregoing, if the Exchange Ratio as
calculated pursuant to the preceding sentence and without regard to this
sentence (i) is less than the Minimum Value, then the Exchange Ratio will be
equal to the "Minimum Value," or (ii) is greater than the "Maximum Value,"
then the Exchange Ratio will be equal to the "Maximum Value." "Minimum Value"
will be $16.875 and "Maximum Value" will be $19.6875.

    (b) Subject to the immediately following sentence and to Section 3.1(c) and
        3.1(e), each record holder of shares of FAL Common Stock immediately
        prior to the Effective Time shall be entitled to elect to receive cash
        for all or any part of such shares of FAL Common Stock (a "Cash
        Election"). Notwithstanding the foregoing, the aggregate number of
        shares of FAL Common Stock that may be converted into the right to
        receive cash consideration shall not exceed the Cash Election Number.
        To the extent not covered by a properly given Cash Election, all shares
        of FAL Common Stock issued and outstanding immediately prior to the
        Effective Time shall, except as provided in Section 3.1(g), be
        converted solely into shares of SUG Common Stock.

"Cash Election Number" shall equal, subject to reduction pursuant to Section
3.1(e), the amount by which (i) 50% of the number of shares of FAL Common
Stock outstanding immediately prior to the Effective Time, exceeds (ii) the
sum of (a) the number of shares of FAL Common Stock to be exchanged for cash
in lieu of fractional shares pursuant to Section 3.1(g), and (b) the number of
Dissenting Shares.


                                      A-7

<PAGE>

   (c) If the aggregate number of shares of FAL Common Stock covered by Cash
       Elections (the "Cash Election Shares") exceeds the Cash Election
       Number, each Cash Election Share shall be converted into (i) the right
       to receive an amount in cash, without interest, equal to the product of
       (a) $23.50 and (b) a fraction (the "Cash Fraction"), the numerator of
       which shall be the Cash Election Number and the denominator of which
       shall be the total number of Cash Election Shares, and (ii) a number of
       shares of SUG Common Stock equal to the product of (a) $23.50 divided
       by the Exchange Ratio and (b) a fraction equal to one minus the Cash
       Fraction.

   (d) SUG will make all computations to give effect to this Section 3.1.

   (e) If, after having made the calculation under Section 3.1(b), the value
       of the SUG Common Stock (excluding fractional shares to be paid in cash)
       to be issued in the Merger, valued at the lesser of the Average Trading
       Price as of the Closing Date and the closing price of SUG Common Stock
       on the last trading day before the Closing Date (or, if determined to
       be more appropriate to ensure the status of the Merger as a
       reorganization under Section 368(a)(1)(A) of the IRC, the trading price
       as of the time of the Closing), as reported on the New York Stock
       Exchange ("NYSE"), is less than 50% of the total consideration to be
       paid in exchange for the shares of FAL Common Stock (including, without
       limitation, the amount of cash to be paid in lieu of fractional shares
       and treating any Dissenting Shares as having been exchanged for the
       Cash Consideration) (the "Total Consideration"), then the Cash Election
       Number shall be reduced to the extent necessary so that the value of
       the SUG Common Stock to be issued in the Merger (as determined above)
       is 50% of the Total Consideration.

   (f) Each holder of FAL Common Stock shall surrender all such holder's
       certificates formerly representing ownership of FAL Common Stock in the
       manner provided in Section 3.2. All such shares of FAL Common Stock,
       when so converted, shall no longer be outstanding and shall be canceled
       and automatically converted into the right to receive the Merger
       Consideration (and cash in lieu of fractional shares) therefor upon the
       surrender of such certificate in accordance with Section 3.2. Any
       payment made pursuant to this Section 3.1 shall be made net of
       applicable withholding taxes to the extent such withholding is required
       by law.

   (g) No fractional share of SUG Common Stock shall be issued in connection
       with the Merger. Each holder of shares of FAL Common Stock shall be
       entitled to receive in lieu of any fractional share of SUG Common Stock
       to which such holder otherwise would have been entitled pursuant to
       this Section 3.1 (after taking into account all shares of FAL Common
       Stock then held of record by such holder) a cash payment in an amount
       equal to the product of (i) the fractional interest of a share of SUG
       Common Stock to which such holder otherwise would have been entitled
       and (ii) the closing price of a share of SUG Common Stock on the NYSE
       on the trading day immediately prior to the Effective Time. Payment of
       such amounts shall be made by SUG.

SECTION 3.2  EXCHANGE OF FAL COMMON STOCK CERTIFICATES.

   (a) SUG's registrar and transfer agent, or such other bank or trust company
       as may be selected by SUG and be reasonably acceptable to FAL, will act
       as paying agent ("Paying Agent") for the holders of FAL Common Stock in
       connection with the Merger, pursuant to an agreement providing for the
       matters set forth in this Section 3.2 and such other matters as may be
       appropriate and the terms of which shall be reasonably satisfactory to
       SUG and FAL.

   (b) (i) Not fewer than 15 business days prior to the Closing Date, SUG will
       cause the Paying Agent to mail a form of election (the "Form of
       Election") to holders of record of shares of FAL Common Stock (as of a
       record date as close as practicable to the date of mailing). In
       addition, the Paying Agent will use its reasonable efforts to make the
       Form of Election available to the Persons who become stockholders of
       FAL during the period between such record date and the Election
       Deadline. Any election to receive Cash Consideration contemplated by
       Section 3.1(b) will have been properly made only if the Paying Agent
       shall have received at its designated office or offices, by 4:00 p.m.,
       Eastern Time, on the third business day prior to the Closing Date (the
       "Election Deadline"), a Form of Election properly completed, as set
       forth in such Form of Election. An election may be revoked only by
       written notice received by the Paying Agent prior to the Election
       Deadline. In addition, all elections shall automatically be revoked if
       the Paying Agent is notified by SUG and FAL that the Merger has been
       abandoned. SUG shall have the discretion, which it may delegate in
       whole or in part to the Paying Agent, to determine whether Forms of
       Election have been properly completed, signed and submitted or revoked
       pursuant to this Section 3.2(b), and to disregard


                                      A-8

<PAGE>

       immaterial defects in Forms of Election. The decision of SUG (or the
       Paying Agent, as the case may be) in such matters shall be conclusive
       and binding.

   (c) At the Effective Time of the Merger, SUG will instruct the Paying Agent
       to promptly, and in any event not later than three (3) business days
       following the Effective Time, mail (and to make available for
       collection by hand) to each holder of record of a certificate or
       certificates, which immediately prior to the Effective Time represented
       outstanding shares of FAL Common Stock (the "Certificates"), whose
       shares of FAL Common Stock were converted pursuant to Section 3.1(a)
       into the right to receive the Merger Consideration (and cash in lieu of
       fractional shares) (i) a letter of transmittal (which shall specify
       that delivery shall be effected, and risk of loss and title to the
       Certificates shall pass, only upon delivery of the Certificates to the
       Paying Agent and shall be in such form and have such other provisions
       as SUG may reasonably specify) and (ii) instructions (which shall
       provide that at the election of the surrendering holder Certificates
       may be surrendered, and payment therefor collected, by hand delivery)
       for use in effecting the surrender of the Certificates in exchange for
       payment of the Merger Consideration (and cash in lieu of fractional
       shares). Upon surrender of a Certificate for cancellation to the Paying
       Agent or to such other agent or agents as may be appointed by SUG,
       together with such letter of transmittal, duly executed, the holder of
       such Certificate shall be entitled to receive in exchange therefor the
       Merger Consideration for each share of FAL Common Stock formerly
       represented by such Certificate (and cash in lieu of fractional
       shares), to be mailed (or made available for collection by hand if so
       elected by the surrendering holder) within three (3) business days of
       receipt thereof, and the Certificate so surrendered shall forthwith be
       canceled. If payment of the Merger Consideration (and cash in lieu of
       fractional shares) is to be made to a Person other than the
       Person in whose name the surrendered Certificate is registered, it
       shall be a condition of payment that the Certificate so surrendered
       shall be properly endorsed or shall be otherwise in proper form for
       transfer and that the Person requesting such payment shall have paid
       any transfer and other Taxes required by reason of the payment of the
       Merger Consideration (and cash in lieu of fractional shares) to a
       Person other than the registered holder of the Certificate surrendered
       or shall have established to the satisfaction of the Surviving
       Corporation that such Tax either has been paid or is not applicable.
       Until surrendered as contemplated by this Section 3.2, each Certificate
       (other than Certificates representing FAL Common Stock held by SUG or
       Dissenting Shares) shall be deemed at any time after the Effective Time
       to represent only the right to receive the Merger Consideration (and
       cash in lieu of fractional shares) as contemplated by this Section 3.2.

   (d) In the event any Certificate shall have been lost, stolen or destroyed,
       upon the making of an affidavit of that fact by the Person claiming
       such Certificate to be lost, stolen or destroyed, the Paying Agent will
       issue in exchange for such lost, stolen or destroyed Certificate the
       Merger Consideration (and cash in lieu of fractional shares)
       deliverable in respect thereof as determined in accordance with this
       Article III, PROVIDED THAT the Person to whom the Merger Consideration
       (and cash in lieu of fractional shares) is paid shall, as a condition
       precedent to the payment thereof, give the Paying Agent a bond in such
       sum as it may ordinarily require and indemnify the Surviving
       Corporation in a manner satisfactory to it against any claim that may
       be made against the Surviving Corporation with respect to the
       Certificate claimed to have been lost, stolen or destroyed.

   (e) After the Effective Time, the stock transfer books of FAL shall be
       closed and there shall be no transfers on the stock transfer books of
       the Surviving Corporation of shares of FAL Common Stock that were
       outstanding immediately prior to the Effective Time. If, after the
       Effective Time, Certificates are presented to the Surviving
       Corporation, they shall be canceled and exchanged for the Merger
       Consideration (and cash in lieu of fractional shares) as provided in
       this Article III.

   (f) The Surviving Corporation shall not be liable to any holder of FAL
       Common Stock for Merger Consideration (and cash in lieu of fractional
       shares) delivered to a public official pursuant to any applicable
       abandonment, escheat or similar law. Any amounts remaining unclaimed by
       holders of any such shares of FAL Common Stock seven years after the
       Effective Time (or such earlier date immediately prior to the time at
       which such amounts would otherwise escheat to or become property of any
       Governmental Body) shall, to the extent permitted by applicable law,
       become the property of the Surviving Corporation, free and clear of any
       claims or interest of any such holders or their successors, assigns or
       personal representatives previously entitled thereto.

SECTION 3.3 DISSENTING SHARES. Notwithstanding any provision of this Agreement
to the contrary, the shares of any holder of FAL Common Stock who has demanded
and perfected appraisal rights for such shares in accordance with the MBCL and


                                      A-9

<PAGE>


who, as of the Effective Time, has not effectively withdrawn or lost such
appraisal rights ("Dissenting Shares"), shall not be converted into or
represent a right to receive the Merger Consideration (and cash in lieu of
fractional shares) pursuant to Section 3.1, but the holder thereof shall only
be entitled to such rights as are granted by the MBCL. Notwithstanding the
foregoing, if any holder of shares of FAL Common Stock who demands appraisal
of such shares under the MBCL shall effectively withdraw the request for
appraisal or lose the right to appraisal, then, as of the later of the
Effective Time and the occurrence of such event, such holder's shares shall
automatically be converted into and represent only the right to receive the
Merger Consideration and cash in lieu of fractional shares, without interest
thereon, upon surrender of the certificate representing such shares. FAL shall
give SUG prompt notice of any demands received by FAL for appraisal of FAL
Common Stock, and, prior to the Effective Time, SUG shall have the right to
participate in all negotiations and proceedings with respect to such demands.
Prior to the Effective Time, FAL shall not, except with the prior written
consent of SUG, make any payment with respect to or offer to settle, any such
demands.

                                   ARTICLE IV

                      REPRESENTATIONS AND WARRANTIES OF SUG

SUG, as to SUG and its Subsidiaries, represents and warrants to FAL that:

SECTION 4.1 ORGANIZATION, EXISTENCE AND QUALIFICATION. SUG is a corporation
duly incorporated, validly existing, and in good standing under the laws of
the State of Delaware, with full corporate power and authority to conduct its
business as it is now being conducted, to own or use the properties and assets
that it purports to own or use, to perform its obligations under all Contracts
to which it is a party, and to execute and deliver this Agreement. SUG is duly
qualified to do business as a foreign corporation and is in good standing
under the laws of each state or other jurisdiction in which either the
ownership or use of the properties owned or used by it, or the nature of the
business conducted by it, requires such qualification as a foreign corporation
except for such failures to be so qualified or in good standing as are not,
individually or in the aggregate, reasonably likely to have a SUG Material
Adverse Effect.

SECTION 4.2 CAPITALIZATION. As of the date of this Agreement, the authorized
capital stock of SUG consists of (i) 50,000,000 shares of SUG Common Stock, of
which 31,288,321 shares were issued and 31,236,696 were outstanding on
September 30, 1999, and (ii) 1,500,000 shares of Cumulative Preferred Stock,
no par value, none of which are issued or outstanding. The issued and
outstanding shares of SUG Common Stock have been validly issued and are fully
paid and nonassessable. The shares of SUG Common Stock to be issued as the
Merger Consideration have been duly authorized and when issued and delivered
in accordance with the terms of this Agreement, will have been validly issued
and will be fully paid and nonassessable and the issuance thereof is not
subject to any preemptive or other similar right. Except as specifically
described in the SUG SEC Documents delivered to FAL prior to the date of this
Agreement, as of the date of this Agreement, no shares of SUG Common Stock are
held, in treasury or otherwise, by SUG or any of its Subsidiaries and except
as set forth in Section 4.2 of the SUG Disclosure Schedule, as of the date of
this Agreement, there are no outstanding (i) securities convertible into SUG

       by such Tax Returns and have paid all other Taxes as are due or made
       adequate provision therefor in accordance with GAAP except where the
       failures to so file, pay or discharge are not, individually or in the

       examinations relating to any Tax matters. There are no Tax liens on any
       assets of SUG or its Subsidiaries. As of the date of this Agreement,
       SUG and its Subsidiaries have not granted any waiver of any statute of
       limitations with respect to, or any extension of a period for the
       assessment of, any Tax. The accruals and reserves (including deferred
       taxes) reflected in the SUG Balance Sheet are in all material respects

       contested) in accordance with GAAP.

       undertaken for reasons unrelated to the transactions contemplated by
       this Agreement.

SECTION 4.11 INTELLECTUAL PROPERTY. SUG has no Knowledge of (i) any
infringement or claimed infringement by it of any patent rights or copyrights
of others or (ii) any infringement of the patent or patent license rights,

       in which either the ownership or use of the properties owned or used by
       it, or the nature of the business conducted by it, requires such
       qualification as a foreign corporation except for such failures to be
       so qualified or in good standing as are not, individually or in the
       aggregate, reasonably likely to have a FAL Material Adverse Effect.

   (b) FAL has delivered to SUG copies of the Organizational Documents, as
       currently in effect, of each Acquired Company.

SECTION 5.2 CAPITALIZATION. The capital stock of FAL consists of 2,951,334

convertible into FAL Common Stock or other capital stock of FAL or any of its
Subsidiaries, (ii) warrants or options to purchase FAL Common Stock or other

                    significant change in the Ordinary Course of Business or

                    businesses and assets as SUG may reasonably request;
                    PROVIDED, HOWEVER, that nothing herein will obligate any

                    Combination that FAL's Board of Directors determines, in
                    its good faith judgment, after consultation with and the
                    receipt of the advice of its financial advisor and outside
                    counsel with customary qualifications, is a Superior
                    Proposal, (i) furnish information to, and negotiate,
                    explore or otherwise engage in substantive discussions
                    with such third party, only if FAL's Board of Directors
                    determines, in its good faith judgment after consultation
                    with its financial advisors and outside legal counsel,
                    that it is reasonably necessary in order to comply with
                    its fiduciary duties under applicable law and (ii) take
                    and disclose to FAL's stockholders a position with respect
                    to another Business Combination proposal, or amend or
                    withdraw such position, pursuant to Rule 14d-9 and 14e-2
                    under the Exchange Act, or make such disclosure to FAL's
                    stockholders which in the good faith judgment of FAL's
                    Board of Directors is required by applicable law, based on
                    the advice of its outside counsel. Prior to furnishing any
                    non-public information to, entering into negotiations with
                    or accepting a Superior Proposal from such third party,
                    FAL will (i) provide written notice to SUG to the effect
                    that it is furnishing information to or entering into
                    discussions or negotiations with such third party and (ii)
                    receive from such third party an executed confidentiality
                    agreement containing substantially the same terms and
                    conditions as the Confidentiality Agreement. FAL will
                    immediately cease and cause to be terminated any existing
                    solicitation, initiation, encouragement, activity,
                    discussion or negotiations with any parties conducted
                    heretofore by FAL or any of its representatives with
                    respect to any Business Combination.

              (2)   Except as expressly permitted by this Section 6.1(h),
                    neither the FAL Board of Directors nor any committee
                    thereof may, (i) withdraw or modify, or propose publicly
                    to withdraw or modify, in a manner adverse to SUG, the
                    approval or recommendation by such Board of Directors or
                    such committee of the Merger or this Agreement, (ii)
                    approve or recommend, or propose publicly to approve or
                    recommend, a  Business Combination or (iii) cause FAL to
                    enter into any letter of intent, agreement in principle,
                    acquisition agreement or other similar agreement related
                    to any Business Combination. Notwithstanding the
                    foregoing, prior to the time at which the FAL
                    Stockholders' Approval has been obtained, in response to
                    an unsolicited Business Combination proposal from a third
                    party, if FAL's Board of Directors determines, in its good
                    faith judgment, after consultation with and the receipt of
                    the advice of its financial advisor and outside counsel
                    with customary qualifications, that such proposal is a
                    Superior Proposal and that failure to do any of the
                    actions set forth in clauses (i), (ii) or (iii) above
                    would create a reasonable possibility of a breach of the
                    fiduciary duties of FAL's Board of Directors under
                    applicable law, FAL's Board of Directors may (i) withdraw
                    or modify its approval or recommendation of the Merger or
                    this Agreement, approve or recommend a Business
                    Combination or cause FAL to enter into a Business
                    Combination and (ii) negotiate with a third party with
                    respect to such Business Combination proposal and, subject
                    to FAL having paid to SUG the fees described in Section
                    8.3(a) hereof and having entered into a definitive
                    agreement with respect to such Business Combination
                    proposal, terminate this Agreement; PROVIDED, HOWEVER,
                    that prior to entering into a definitive agreement with
                    respect to a Business Combination proposal, FAL shall give
                    SUG at least five (5) day's notice thereof, and shall
                    cause its Representatives to, negotiate with SUG to make
                    such adjustments in the terms and conditions of this
                    Agreement as would enable FAL to proceed with the
                    transactions contemplated herein on such adjusted terms;
                    PROVIDED, FURTHER, that if FAL and SUG are unable to reach
                    an agreement on such adjustments within five (5) days
                    after such notice from FAL, FAL may enter into such
                    definitive agreement, subject to the provisions of Article
                    VIII.

              (3)   FAL shall notify SUG orally and in writing of any such
                    inquiries, offers or proposals (including, without
                    limitation, the material terms and conditions of any such
                    offer or proposal and the identity of the Person making
                    it), within one business day of the receipt thereof, shall
                    use all reasonable efforts to keep SUG informed of the
                    status and details of any such inquiry, offer or proposal
                    and shall give SUG two (2) days advance notice of the
                    first delivery of non-public information to such Person.
                    If any such inquiry, offer or proposal is in writing, FAL
                    shall promptly deliver to SUG a copy of such inquiry,
                    offer or proposal.

              (4)   For purposes of this Agreement, (i) "Business Combination"
                    means (other than the transactions contemplated or

                    other business combination, share exchange, sale of shares
                    of capital stock, tender offer or exchange offer or similar
                    transaction involving FAL or any of its Subsidiaries, (B)
                    acquisition in any manner, directly or indirectly, of a


                                      A-25

<PAGE>

                    material interest in any capital stock of, or a material
                    equity interest in a substantial portion of the assets of,
                    FAL or any of its Subsidiaries, including any single or
                    multi-step transaction or series of related transactions
                    that is structured to permit a third party to acquire
                    beneficial ownership of a majority or greater equity
                    interest in FAL or any of its Subsidiaries, or (C) the
                    acquisition in any manner, directly or indirectly, of any
                    material portion of the business or assets (other than
                    immaterial or insubstantial assets or inventory in the
                    Ordinary Course of Business) of FAL or any of its
                    Subsidiaries and (ii) "Superior Proposal" means a proposed
                    Business Combination involving at least 50% of the shares
                    of capital stock or a material portion of the assets of
                    FAL that FAL's Board of Directors determines, after
                    consulting with FAL's financial advisors and outside
                    counsel, is financially superior to the transactions
                    contemplated hereby and it appears that the party making
                    the proposal is reasonably likely to have the funds
                    necessary to consummate the Business Combination.

         (i)  SOLICITATION OF PROXIES; FAL PROXY STATEMENT. Subject to Section
              6.1(h), FAL shall use its reasonable best efforts to solicit from
              its stockholders proxies in favor of the Merger and shall take
              all other action necessary or, in the reasonable opinion of SUG,
              advisable to secure the FAL Stockholders' Approval.

                    its stockholders (including all adjournments thereof,
                    the "FAL Meeting") for the purpose of securing the FAL
                    Stockholders' Approval, (ii) distribute to its
                    stockholders the FAL Proxy Statement in accordance with
                    applicable federal and state law and with its
                    Organizational Documents, (iii) subject to the fiduciary
                    duties of its Board of Directors, recommend to its
                    stockholders the approval and adoption of this Agreement
                    and the transactions contemplated hereby and (iv)
                    cooperate and consult with SUG with respect to each of
                    the foregoing matters.

              (2)   The FAL Meeting for the purpose of securing the FAL
                    Stockholders' Approval, including any adjournments thereof,
                    will be held on such date or dates as FAL and SUG mutually
                    determine.

         (k)  RULE 145 LETTERS.  FAL shall promptly identify to SUG all
              officers and directors of any Acquired Company and any other
              persons who are "affiliates" within the meaning of such term as
              used in Rule 145 under the Securities Act ("Rule 145
              Affiliates"), and FAL shall use its reasonable efforts to
              provide to SUG undertakings from such persons ("Rule 145
              Letters") to the effect that no disposition of shares of SUG
              Common Stock received in the Merger will be made by such persons
              except within the limits and in accordance with the applicable
              provisions of said Rule 145, as amended from time to time, or
              except in a transaction which, in the opinion of legal counsel
              satisfactory to SUG, is exempt from registration under the
              Securities Act.

         (l)  FINANCING ACTIVITIES.  FAL shall, and shall cause its
              Subsidiaries to, cooperate, to the fullest extent commercially

              refinancing by the Acquired Companies of the current maturities
              of any of their indebtedness, and any repurchase, redemption or
              prepayment by any of the Acquired Companies of any of its
              indebtedness that may be required prior to or because of the
              Merger or that SUG may request that the Acquired Companies
              effect prior to the Merger, so as to permit SUG to have the
              maximum opportunity to refinance, on or promptly after the
              Closing Date without any penalty except as may be due pursuant
              to the terms of the Acquired Companies' indebtedness as in
              effect on the date of this Agreement, any of the Acquired
              Companies' indebtedness outstanding on the Closing Date;
              PROVIDED, HOWEVER, that no Acquired Company shall be required to
              consummate prior to the Effective Time any such refinancing,
              repurchase, redemption or repayment requested by SUG.

covenants and agreements:

     (a) GOVERNMENTAL APPROVALS; THIRD PARTY CONSENTS. SUG will use its
         reasonable best efforts at SUG's sole expense to obtain all necessary

                    Subsidiary of the Surviving Corporation employee benefit
                    plans or arrangements that are no less favorable, in the
                    aggregate, than the FAL Benefit Plans listed in Section
                    5.18(j) of the FAL Disclosure Schedule offered to the
                    Employees immediately prior to the date of this

                    Date.

              (3)   All vacation time earned by the Employees prior to the
                    Closing Date must be taken by the end of the calendar
                    year in which the Closing Date occurs, except where the
                    Employee is requested by FAL or SUG to forego their

         of SUG Common Stock constituting the Stock Consideration to be listed
         on the NYSE, subject to official notice of issuance thereof.

         Acquired Company, and shall discharge when due any and all liabilities
         of any Acquired Company under such collective bargaining agreements
         relating to periods after the Effective Time.

     (f) SUG DISCLOSURE SCHEDULE. On the date hereof, SUG has delivered to FAL

                    Business in accordance with prudent business judgment and
                    consistent with past practice and policy, and maintain its
                    assets in good repair, order and condition, reasonable wear

                    reasonable times, reasonable access to such of the
                    offices, properties and employees of SUG and its
                    Subsidiaries, and shall disclose, and make available to
                    FAL and its Representatives all books, papers and records
                    to the extent that they relate to the ownership,
                    operation, obligations and liabilities of or pertaining to
                    SUG, its Subsidiaries and their respective businesses and
                    assets. Without limiting the application of the
                    Confidentiality Agreement, all documents or information
                    furnished by SUG and its Subsidiaries hereunder shall be

              (2)   SUG will notify FAL as promptly as practicable of any

                    involving or affecting SUG or any of its Subsidiaries or
                    the transactions contemplated by this Agreement, and shall
                    use reasonable efforts to keep FAL fully informed of such
                    events and permit FAL's Representatives access to all
                    materials prepared in connection therewith consistent with
                    any applicable Legal Requirement or Contract.

SECTION 6.3 ADDITIONAL AGREEMENTS.

     (a) THE REGISTRATION STATEMENT AND THE FAL PROXY STATEMENT. As soon as
         practicable after the date hereof, FAL and SUG shall take such
         reasonable steps as are necessary for the prompt preparation and
         filing with the SEC of (i) the FAL Proxy Statement by FAL and (ii)
         the Registration Statement, which will include certain information
         contained in the FAL Proxy Statement, by SUG. The foregoing shall
         include without limitation: (i) obtaining and furnishing the
         information required to be included therein, (ii) after consultation
         between FAL and SUG, responding promptly to any comments made by the
         SEC with respect to the FAL Proxy Statement and the Registration
         Statement and any amendments and preliminary version thereof and
         (iii) causing the Registration Statement to become effective, and the
         FAL Proxy Statement to be mailed to FAL's stockholders at the
         earliest practicable date. FAL agrees, as to information with respect
         to FAL, its officers, directors, stockholders and Subsidiaries
         contained in the Registration Statement and the FAL Proxy Statement,
         and SUG agrees, as to information with respect to SUG, its officers,
         directors, stockholders and Subsidiaries contained in the
         Registration Statement and the FAL Proxy Statement, that such
         information, in the case of the FAL Proxy Statement at the time of
         the mailing of the FAL Proxy Statement and (as then amended or
         supplemented) at the time of the FAL Meeting, or in the case of the
         Registration Statement at the time of the mailing of the FAL Proxy
         Statement (as then amended or supplemented), at the time of the FAL
         Meeting and at the effective time of the Registration Statement, will
         not contain any untrue statement of material fact required to be
         stated therein or necessary in order to make the statements therein,
         in light of the circumstances under which they are made, not
         misleading. No representation, warranty, covenant or agreement is
         made by or on behalf of FAL with respect to information supplied by
         any other Person for inclusion in the FAL Proxy Statement or the
         Registration Statement. No representation, warranty, covenant or
         agreement is made by or on behalf of SUG with respect to information
         supplied by any other Person for inclusion in the FAL Proxy Statement
         or the Registration Statement. No filing of, or amendment or
         supplement to, the FAL Proxy Statement or the Registration


                                      A-28

<PAGE>

         Statement shall be made by any party hereto without providing the
         other party with the opportunity to review and comment thereon
         (except for any ongoing SEC reporting required of SUG or FAL that
         will be incorporated by reference). If at any time prior to the
         Effective Time any information relating to any party hereto or any of
         their respective officers, directors, stockholders or Subsidiaries,
         should be discovered by any party hereto which should be set forth in
         an amendment or supplement to the FAL Proxy Statement or the
         Registration Statement so that the FAL Proxy Statement or the
         Registration Statement would not include any untrue statement of a
         material fact or omit to state any material fact necessary to make
         the statements therein, in light of the circumstances under which
         they were made, not misleading, the party which discovers such
         information shall promptly notify the other party hereto and an
         appropriate amendment or supplement describing such information shall
         be promptly prepared, filed with the SEC and, to the extent required
         by law, disseminated to the stockholders of FAL, as may be necessary.

     (b) FURTHER ASSURANCES. Each of SUG and FAL agrees, and FAL agrees to
         cause its Subsidiaries, to take all such reasonable and lawful action
         as may be necessary or appropriate in order to effectuate the Merger
         in accordance with this Agreement as promptly as possible. If, at any
         time after the Effective Time, any such further action is necessary

         of all Governmental Bodies required in order to consummate the
         transactions contemplated hereby shall have been obtained by Final

         operations, properties, financial condition or results of operations
         of the Surviving Corporation, or which would otherwise, in the

         without limitation of the condition set forth in the immediately
         preceding sentence, the Massachusetts Department of

         In addition, all consents and approvals required, under the terms of
         any note, bond or indenture listed in Section 5.4 of the FAL

SECTION 9.1  DIRECTORS' AND OFFICERS' INDEMNIFICATION.

     (a) INDEMNIFICATION AND INSURANCE. For a period of six years after the
         Effective Time, the Surviving Corporation will indemnify and hold
         harmless the present and former officers and directors of FAL and its
         Subsidiaries (the "Indemnified Parties") in respect of acts or
         omissions occurring prior to the Effective Time to the extent provided
         under FAL's articles of organization and bylaws in effect on the date
         hereof; PROVIDED, HOWEVER, that if any claim or claims are asserted or
         made within such six-year period, all rights to indemnification in
         respect of such claims shall continue until the final disposition of
         any and all such claims. For six years after the Effective Time, the
         Surviving Corporation will use its reasonable best efforts to provide
         officers' and directors' liability insurance in respect of acts or
         omissions occurring prior to the Effective Time covering each such
         person currently covered by FAL's officers' and directors' liability
         insurance policy on terms with respect to coverage and amount no less
         favorable than those of such policy in effect on the date hereof;
         PROVIDED, HOWEVER, that in satisfying its obligation under this
         Section, if the annual premiums of such insurance coverage exceed 200%
         of the previous year's premiums, the Surviving Corporation will be
         obligated to obtain a policy with the best coverage available, in the
         reasonable judgment of the Board of Directors of the Surviving
         Corporation for a cost not exceeding such amount.

     (b) SUCCESSORS. In the event the Surviving Corporation or any of its
         successors or assigns (i) consolidates with or merges into any other
         Person and is not the continuing or surviving corporation or entity
         of such consolidation or merger or (ii) transfers all or
         substantially all of its properties and assets to any Person, then
         and in either such case, proper provisions must be made so that the
         successors and assigns of the Surviving Corporation will assume the
         obligations set forth in this Section 9.1.

     (c) SURVIVAL OF INDEMNIFICATION. To the fullest extent permitted by law,
         from and after the Effective Time, all rights to indemnification as
         of the date hereof in favor of the employees, agents, directors and
         officers of any Acquired Company with respect to their activities as
         such prior to the Effective Time, as provided in their respective
         Organizational Documents in effect on the date hereof, or otherwise
         in effect on the date hereof, will survive the Merger and will
         continue in full force and effect except for amendments to make
         changes permitted by law that would enhance the rights of past or
         present officers and directors to indemnification or advancement of
         expenses in respect of acts or omissions occurring prior to the
         Effective Time for a period of not less than six years from the
         Effective Time (or, in the case of matters occurring prior to the
         Effective Time which have not been resolved prior to the sixth
         anniversary of the Effective Time, until such matters are finally
         resolved).

SECTION 9.2 REPRESENTATIONS AND WARRANTIES. Each and every representation and
warranty of either party shall expire at, and be terminated and extinguished
with, the Effective Time.

                                VOTING AGREEMENT


VOTING AGREEMENT, dated this 4th day of October, 1999, by and between SOUTHERN
UNION COMPANY, a Delaware corporation ("SUG"), and The Jarabek Family Limited
Partnership, Ronald J. Ferris, Bradford J. Faxon, Raymond H. Faxon, Cindy L.J.
Audette, Gilbert C. Oliveira, Jr. and Thomas H. Bilodeau (each a "Stockholder"
and collectively the "Stockholders").

RECITALS:

WHEREAS, the Stockholders currently beneficially own (as such term is used
under the Securities Exchange Act of 1934, as amended, and the rules and
regulations issued thereunder) the shares of common stock, par value $.83 per
share ("Shares"), of Fall River Gas Company, a Massachusetts corporation
("FAL") shown on Schedule A.

WHEREAS, as a condition of entering into the Agreement of Merger, made as of
the date hereof, by and between SUG and FAL (the "Merger Agreement"), SUG has
requested that the Stockholders agree, and the Stockholders have agreed (i) to
enter into a voting agreement and (ii) to give SUG an irrevocable proxy,
coupled with an interest, to vote the Shares held by the Stockholders, in each
case as more fully set forth herein.

NOW, THEREFORE, in consideration of the mutual covenants and agreements set
forth herein, the parties hereby agree as follows:

1.   AGREEMENT TO VOTE SHARES.  Each Stockholder agrees during the term of this
     Agreement to vote, or cause to be voted, the Shares shown opposite the
     Stockholder's name on Schedule A hereto and any other Shares acquired
     after the date hereof, in person or by proxy, in favor of the Merger, the
     adoption and approval of the Merger Agreement and the approval of the
     transactions contemplated by the Merger Agreement at every meeting of the
     stockholders of FAL at which such matters are considered and at every
     adjournment thereof.

2.   GRANT OF IRREVOCABLE PROXY.  Each Stockholder hereby grants to SUG an
     irrevocable proxy, which proxy is coupled with an interest because of the
     consideration recited herein, to exercise, at any time and from time to
     time, all rights and powers of the Stockholder with respect to the Shares
     shown opposite the Stockholder's name on Schedule A hereto to vote, give
     approvals, and receive and waive notices of meetings for the purpose of
     securing the approval and adoption by the stockholders of FAL of the
     Merger Agreement and the consummation of the transactions contemplated
     thereby and to prevent any action that would prevent or hinder in any
     material respect such approval or consummation. By giving this proxy each
     Stockholder hereby revokes any other proxy granted by the Stockholder to
     vote any of the Shares in a manner inconsistent with the foregoing grant.
     The power and authority hereby conferred shall not be terminated by any
     act of the Stockholder or by operation of law, by the dissolution of, by
     lack of appropriate power or authority, or by the occurrence of any other
     event or events and shall be binding upon all its successors and assigns.
     If after the execution of this Agreement the Stockholder shall dissolve,
     cease to have appropriate power or authority, or if any other such event
     or events shall occur, SUG is nevertheless authorized and directed to
     vote the Shares in accordance with the terms of this Agreement as if such
     dissolution, lack of appropriate power or authority or other event or
     events had not occurred and regardless of notice thereof.

3.   NO OTHER GRANT OF PROXY.  Each Stockholder will not, directly or
     indirectly, grant any proxies or powers of attorney with respect to the
     Shares shown opposite the Stockholder's name on Schedule A hereto or
     acquired after the date hereof to any person in connection with its vote,
     consent or other approval sought, in favor of the Merger (as defined in
     the Merger Agreement), the adoption and approval of the Merger Agreement
     and the approval of the transactions contemplated by the Merger
     Agreement, other than as set forth in Sections 1 and 2 hereof.

4.   TRANSFERS.  Each Stockholder will not, nor will such Stockholder permit
     any entity under such Stockholder's control to, sell, transfer, pledge,
     assign or otherwise dispose of (including by gift) (collectively,
     "Transfer"), or consent to any


                                      B-1

<PAGE>

     Transfer of, any Shares or any interest therein or enter into any
     contract, option or other agreement or arrangement (including any profit
     sharing or other derivative arrangement) with respect to the Transfer of,
     any Shares or any interest therein to any person, unless prior to any
     such Transfer the transferee of such Shares agrees to be subject to the
     provisions of this Agreement.

5.   NO SOLICITATION. Until the Merger is consummated or the Merger Agreement
     is terminated in accordance with its terms, each Stockholder shall not,
     nor shall it permit any investment banker, attorney or other advisor or
     representative of such Stockholder to, directly or indirectly through
     another person, solicit, initiate, encourage or otherwise facilitate any
     takeover proposal.

6.   REPRESENTATIONS AND WARRANTIES OF THE STOCKHOLDERS. Each Stockholder as to
     such Stockholder hereby represents and warrants to, and covenants with,
     SUG as follows:

     (a) The Stockholder beneficially owns with power to vote the number of
         Shares shown opposite the Stockholder's name on Schedule A free and
         clear of any and all claims, liens, charges, encumbrances, covenants,
         conditions, restrictions, voting trust arrangements, options and
         adverse claims or rights whatsoever, except as granted hereby or as
         would have no adverse effect on this Agreement and/or the proxy
         granted hereby. The Stockholder does not own of record or
         beneficially any shares of capital stock of FAL or other securities
         representing or convertible into shares of capital stock of FAL
         except as set forth in the preceding sentence, Shares purchased after
         the date hereof which shall become subject to this Agreement and the
         proxy granted hereby, and Shares which any of them may have the right
         to purchase upon exercise of options or warrants;

     (b) The Stockholder has the full right, power and authority to enter into
         this Agreement and to grant an irrevocable proxy to SUG with respect
         to the Shares; there are no options, warrants, calls, commitments or
         agreements of any nature whatsoever pursuant to which any person will
         have the right to purchase or otherwise acquire the Shares owned by
         the Stockholder except as would, if exercised, require such purchaser
         or acquiror to abide by this Agreement and the proxy granted hereby
         with respect thereto; except as provided in this Agreement, the
         Stockholder has not granted or agreed to grant any proxy or entered
         into any voting trust, vote pooling or other agreement with respect
         to the right to vote or give consents or approval of any kind as to
         the Shares which proxy, trust, pooling or other agreement remains in
         effect as of the date hereof and is in conflict with this Agreement
         or the proxy granted hereby;

     (c) The Stockholder is not a party to, subject to or bound by any
         agreement or judgment, order, writ, prohibition, injunction or decree
         of any court or other governmental body that would prevent the
         execution, delivery or performance of this Agreement by the
         Stockholder or the exercise of proxy rights by SUG with respect to the
         Shares;

     (d) This Agreement has been duly and validly executed and delivered by the
         Stockholder and constitutes a legal, valid and binding obligation of
         the Stockholder, enforceable in accordance with its terms, subject
         only to (i) the effect of bankruptcy, insolvency, reorganization or
         moratorium laws or other laws generally affecting the enforceability
         of creditors' rights and (ii) general equitable principles which may
         limit the right to obtain specific performance or other equitable
         remedies; and

     (e) The Stockholder will take all commercially reasonable action necessary
         in order that its representations and warranties set forth in this
         Agreement shall remain true and correct.

7.   STOCKHOLDERS' COVENANTS. Each Stockholder shall not enter into any voting
     trust agreement, give any proxy or other right to vote the Shares or take
     any action that would limit the rights of any holder of the Shares to
     exercise fully the right to vote such Shares that would be in conflict
     with this Agreement or the proxy granted hereby.

8.   SEVERABILITY. If any term, provision, covenant or restriction of this
     Agreement is held by a court of competent jurisdiction to be invalid, void
     or unenforceable, the remainder of the terms, provisions, covenants and
     restrictions of this Agreement shall remain in full force and effect and
     shall in no way be affected, impaired or invalidated.

9.   ASSIGNMENT.  This Agreement shall not be assigned or delegated by any
     party hereto, except that SUG may transfer its rights hereunder to any
     wholly-owned subsidiary of SUG, and except that any assignment of any of
     the Shares by any Stockholder shall require that such Shares remain
     subject to this Agreement and the proxy granted hereby.  This Agreement
     shall be binding upon and inure to the benefit of SUG and its successors
     and assigns and shall be binding upon and inure to the benefit of the
     Stockholders and their permitted successors and any permitted assigns.

10.  SPECIFIC PERFORMANCE.  The parties hereto acknowledge that damages would
     be an inadequate remedy for a breach of this Agreement and that the
     obligations of the parties hereto shall be specifically enforceable.  In
     addition to any other legal or equitable remedies to which SUG would be
     entitled, in the event of a breach or a threatened breach of this
     Agreement by any Stockholder, SUG shall have the right to obtain
     equitable relief, including (but not limited to) an injunction or order
     of specific performance of the terms hereof from a court of competent
     jurisdiction.

     supplemented except upon the execution and delivery of a written agreement
     executed by all of the parties hereto.

        and automatically converted into the right to receive the Merger
        Consideration therefor upon the surrender of such certificate in
        accordance with Section 3.2. Any payment made pursuant to this Section
        3.1 shall be made net of applicable withholding taxes to the extent
        such withholding is required by law.

    (c) Notwithstanding any provision of this Agreement to the contrary, each
        share of PVY Common Stock held in the treasury of PVY immediately prior
        to the Effective Time shall be canceled and extinguished without
        conversion thereof.

    (d) Each share of common stock, par value $1.00 per share, of Newco issued
        and outstanding immediately prior to the Effective Time shall be
        converted into and become one share of common stock, par value $1.00
        per share, of the Surviving Corporation.

SECTION 3.2   EXCHANGE OF PVY COMMON STOCK CERTIFICATES.

    (a) SUG's registrar and transfer agent, or such other bank or trust company
        which has a net capital of not less than $100,000,000, as may be
        selected by SUG and be reasonably acceptable to PVY, will act as paying
        agent ("Paying Agent") for the holders of PVY Common Stock in
        connection with the Merger, pursuant to an agreement providing for the
        matters set forth in this Section 3.2 and such other matters as may be
        appropriate and the terms of which shall be reasonably satisfactory to
        SUG and PVY, to receive the consideration to which holders of PVY
        Common Stock become entitled pursuant to Section 3.1. Contemporaneous
        with the Effective Time, SUG will deposit in trust with the Paying
        Agent, for the benefit of holders of PVY Common Stock, the cash
        necessary to pay the aggregate Merger Consideration as contemplated by
        Section 3.1(a) with respect to each share of PVY Common Stock.

    (b) At the Effective Time of the Merger, SUG will irrevocably instruct the
        Paying Agent to promptly, and in any event not later than eight (8)
        business days following the Effective Time, mail (and to make available
        for collection by hand) to each holder of record of a certificate or
        certificates, which immediately prior to the Effective Time represented
        outstanding shares of PVY Common Stock (the "Certificates"), whose
        shares of PVY Common Stock were converted pursuant to Section 3.1(a)
        into the right to receive the Merger Consideration (i) a letter of
        transmittal (which shall specify that delivery shall be effected, and
        risk of loss and title to the Certificates shall pass, only upon
        delivery of the Certificates to the Paying Agent and shall be in such
        form and have such other provisions as SUG may reasonably specify) and
        (ii) instructions (which shall provide that at the election of the
        surrendering holder Certificates may be surrendered, and payment
        therefor collected, by hand delivery) for use in effecting the
        surrender of the Certificates in exchange for payment of the Merger
        Consideration. Upon surrender of a Certificate for cancellation to the
        Paying Agent or to such other agent or agents as may be appointed by
        SUG, together with such letter of transmittal, duly executed, the
        holder of such Certificate shall be entitled to receive in exchange
        therefor the Merger Consideration for each share of PVY Common Stock
        formerly represented by such Certificate, to be mailed

                                     C-8

<PAGE>


        (or made available for collection by hand if so elected by the
        surrendering holder) within eight (8) business days of receipt
        thereof, and the Certificate so surrendered shall forthwith be
        canceled. If payment of the Merger Consideration is to be made to a
        Person other than the Person in whose name the surrendered Certificate
        is registered, it shall be a condition of payment that the Certificate
        so surrendered shall be properly endorsed or shall be otherwise in
        proper form for transfer and that the Person requesting such payment
        shall have paid any transfer and other Taxes required by reason of the
        payment of the Merger Consideration to a Person other than the
        registered holder of the Certificate surrendered or shall have
        established to the satisfaction of SUG that such Tax either has been
        paid or is not applicable. Until surrendered as contemplated by this
        Section 3.2, each Certificate (other than Certificates representing
        PVY Common Stock held by SUG) shall be deemed at any time after the
        Effective Time to represent only the right to receive the Merger
        Consideration as contemplated by this Section 3.2.

    (c) The Paying Agent shall invest the funds representing the aggregate
        Merger Consideration, as directed by SUG, in (i) direct obligations of
        the United States of America (ii) obligations for which the full faith
        and credit of the United States of America is pledged to provide for
        the payment of principal and interest or (iii) commercial paper rated
        the highest quality by either Moody's Investors Service, Inc. or
        Standard and Poor's Ratings Services, a division of The McGraw Hill
        Companies, Inc.; PROVIDED, HOWEVER, that, notwithstanding anything to
        the contrary in this Agreement, if the Paying Agent is not able or
        refuses to so invest such funds, SUG may deposit such funds in trust
        with another bank or trust company which has a net capital of not less
        than $100,000,000, as may be selected by SUG and be reasonably
        acceptable to PVY, so long as the Paying Agent is allowed to draw on
        such funds to the extent required to pay the Merger Consideration. Any
        net earnings with respect to such funds shall be the property of and
        paid over to SUG as and when requested by SUG.

    (d) In the event any Certificate shall have been lost, stolen or destroyed,
        upon the making of an affidavit of that fact by the Person claiming
        such Certificate to be lost, stolen or destroyed, the Paying Agent will
        issue in exchange for such lost, stolen or destroyed Certificate the
        Merger Consideration deliverable in respect thereof as determined in
        accordance with this Article III; PROVIDED, HOWEVER, that the Person to
        whom the Merger Consideration is paid shall, if required by SUG, as a
        condition precedent to the payment thereof, give the Paying Agent a
        bond in such sum as it may ordinarily require and indemnify SUG in a
        manner satisfactory to it against any claim that may be made against
        SUG with respect to the Certificate claimed to have been lost, stolen
        or destroyed.

    (e) After the Effective Time, the stock transfer books of PVY shall be
        closed and there shall be no transfers on the stock transfer books of
        the Surviving Corporation of shares of PVY Common Stock that were
        outstanding immediately prior to the Effective Time. If, after the
        Effective Time, Certificates are presented to SUG, they shall be
        canceled and exchanged for the Merger Consideration as provided in this
        Article III.

    (f) Any portion of the funds held by the Paying Agent that remain
        undistributed to the former shareholders of PVY for eighteen (18)
        months after the Effective Time shall be delivered by the Paying Agent,
        which shall thereafter act as the Paying Agent, and any former
        shareholders of PVY who have not complied with this Article III prior
        to eighteen (18) months after the Effective Time shall thereafter look
        only as a general creditor to SUG for payment of their claim for the
        Merger Consideration.

    (g) Neither the Surviving Corporation nor SUG shall be liable to any holder
        of PVY Common Stock for Merger Consideration delivered to a public
        official pursuant to any applicable abandonment, escheat or similar
        law. Any amounts remaining unclaimed by holders of any such shares of
        PVY Common Stock five years after the Effective Time (or such earlier
        date immediately prior to the time at which such amounts would
        otherwise escheat to or become property of any Governmental Body)
        shall, to the extent permitted by applicable law, become the property
        of SUG, free and clear of any claims or interest of any such holders or
        their successors, assigns or personal representatives previously
        entitled thereto.

SECTION 3.3   PVY OPTIONS; PVY PERFORMANCE SHARES.

    (a) Each outstanding option to purchase shares of PVY Common Stock or other
        similar interest (collectively, the "PVY Options") granted under any
        stock option plans or under any other plan or arrangement of any
        Acquired Company (the "Acquired Company Option Plans"), together with
        the applicable exercise prices, are disclosed in Section 3.3(a) of the
        PVY Disclosure Schedule. Each PVY Option that is outstanding at the
        Effective Time shall be deemed fully

                                     C-9

<PAGE>

        vested and shall be converted at the Effective Time into a right to
        receive in respect thereof a cash payment in an amount equal to the
        product of (x) the amount by which (i) the Merger Consideration
        exceeds (ii) the exercise price of such PVY Option (if less than (i))
        and (y) the number of shares of PVY Common Stock subject thereto. Such
        cash payment (net of applicable withholding taxes) shall be made on
        the Closing Date or as promptly thereafter as reasonably practicable.

    (b) Each outstanding award of PVY Performance Shares as determined pursuant
        to the PVY Performance Share Plan, is disclosed in Section 3.3(b) of
        the PVY Disclosure Schedule. Copies of the PVY Performance Share Plan
        and the agreements entered into pursuant to the PVY Performance Share
        Plan, which set forth the applicable performance measures and target
        opportunities, have been provided to SUG prior to the date of this
        Agreement. In accordance with the terms of the PVY Performance Share
        Plan, the target opportunities for each outstanding award of PVY
        Performance Shares outstanding at the Effective Time shall be deemed
        fully earned for the entire "Performance Periods" (as such term is
        defined in the PVY Performance Share Plan). Each PVY Performance Share
        outstanding at the Effective Time shall be canceled and automatically
        converted into a right to receive a cash payment in an amount equal to
        the Merger Consideration. Any payment made pursuant to this Section
        3.3(b) shall be made net of applicable withholding taxes to the extent
        such withholding is required by law, and shall be made on the Closing
        Date or as promptly thereafter as reasonably practicable.

                  the Acquired Companies shall permit SUG and its
                  Representatives to have, on reasonable notice and at
                  reasonable times, reasonable access to such of the offices,
                  properties and employees of the Acquired Companies in a
                  manner that will not unreasonably disrupt the operations of
                  the Acquired Companies or their relationship with their
                  customers, suppliers or employees, and shall disclose, and
                  make available to SUG and its Representatives in a manner
                  that will not unreasonably disrupt the operations of the
                  Acquired Companies or their relationship with their
                  customers, suppliers or employees, all books, papers and
                  records (other than confidentiality agreements related to a
                  possible sale of PVY entered into prior to the date of this
                  Agreement) to the extent that they relate to the ownership,
                  operation, obligations and liabilities of or pertaining to
                  the Acquired Companies, their businesses, assets and
                  liabilities. Without limiting the application of the
                  Confidentiality Agreement dated October 6, 1999 between PVY
                  and SUG (the "Confidentiality Agreement"), all documents or
                  information furnished by the Acquired Companies hereunder
                  shall be subject to the Confidentiality Agreement.

             (2)  PVY will notify SUG as promptly as practicable of any
                  significant change in the Ordinary Course of Business or
                  operation of any of the Acquired Companies and of any
                  material complaints, investigations or hearings (or
                  communications indicating that the same may be contemplated)
                  by any Governmental Body, or the institution or overt threat
                  or settlement of any material Proceeding involving or
                  affecting any of the Acquired Companies or the transactions
                  contemplated by this Agreement, and shall use reasonable
                  efforts to keep SUG fully informed of such events and permit
                  SUG's Representatives access to all materials prepared in
                  connection therewith, consistent with any applicable Legal
                  Requirement or Contract.

             (3)  As promptly as practicable after SUG's request, PVY will
                  furnish such financial and operating data and other
                  information pertaining to the Acquired Companies and their
                  businesses and assets as SUG may reasonably request;
                  PROVIDED, HOWEVER, that nothing herein will obligate any of
                  the Acquired Companies to take actions that would
                  unreasonably disrupt its Ordinary Course of Business or
                  violate the terms of any Legal Requirement or Contract to
                  which the Acquired Company is a party or to which any of its
                  assets is subject in providing such information, or to incur
                  any costs with respect to SUG's external

                                    C-20

                  event a report by such auditors is requested by SUG)

                  auditor's report required by or for SUG.

    (d) GOVERNMENTAL APPROVALS; THIRD PARTY CONSENTS. PVY will use its
        commercially reasonable best efforts at PVY's sole expense (except as
        provided otherwise in the last sentence of Section 6.1(n)) to obtain

        in connection with the transactions contemplated hereby under any
        license, lease, permit or Contract applicable to the Acquired
        Companies, including, without limitation, the Letters of Tax Good
        Standing referred to in Section 7.1(i), the approvals of those

        by a wholly-owned Subsidiary to PVY or another wholly-owned Subsidiary,
        (B) dividends by a less than wholly-owned Subsidiary consistent with

        (iii) redeem, repurchase or otherwise acquire any shares of its capital
        stock or the capital stock of any Subsidiary other than (A)
        redemptions, repurchases and other acquisitions of shares of capital
        stock in connection with the administration of employee benefit and

        delivery, sale, award, pledge, disposal or other encumbrance of, any
        shares of its or their capital stock of any class or any securities
        convertible into or exchangeable for, or any rights, warrants or
        options to acquire, any such shares or convertible or exchangeable
        securities, other than the issuance of shares of PVY Common Stock
        pursuant to (i) outstanding grants or awards made prior to the date of
        this Agreement under the PVY Benefit Plans and Acquired Company Option
        Plans and (ii) any dividend reinvestment plan of PVY in effect as of
        the date hereof.

        for costs deferred for Y2K.

    (h) NO SHOPPING.

                  or encourage submission of proposals or offers from any
                  Person relating to, or that could reasonably be expected to
                  lead to, a Business Combination or participate in any
                  negotiations or substantive discussions regarding, or furnish
                  to any other Person any information with respect to, or
                  otherwise cooperate in any way with, or assist or participate
                  in, facilitate or encourage, any effort or attempt by any
                  other Person to do or seek a Business Combination; PROVIDED,
                  HOWEVER, that, prior to the PVY Shareholders' Approval, PVY
                  may, in response to an unsolicited written proposal from a
                  third party with respect to a Business Combination that PVY's
                  Board of Directors determines, in its good faith judgment,
                  after consultation with and the receipt of the advice of its
                  financial advisor and outside counsel with customary
                  qualifications, is a Superior Proposal, (i) furnish
                  information to, and negotiate, explore or otherwise engage in
                  substantive discussions with such third party, only if PVY's
                  Board of Directors determines, in its good faith judgment
                  after consultation with its financial advisors and outside
                  legal counsel, that it is reasonably necessary in order to
                  comply with its fiduciary duties under applicable law and
                  (ii) take and disclose to PVY's shareholders a position with
                  respect to another Business Combination

                                    C-21

<PAGE>

                  proposal, or amend or withdraw such position, pursuant to
                  Rule 14d-9 and 14e-2 under the Exchange Act, or make such
                  disclosure to PVY's shareholders which in the good faith
                  judgment of PVY's Board of Directors, based on the advice of
                  its outside counsel, is required by applicable law. Prior to
                  furnishing any non-public information to, entering into
                  negotiations with or accepting a Superior Proposal from such
                  third party, PVY will (i) provide written notice to SUG to
                  the effect that it is furnishing information to or entering
                  into discussions or negotiations with such third party and
                  (ii) receive from such third party an executed
                  confidentiality agreement containing substantially the same
                  terms and conditions as the Confidentiality Agreement. PVY
                  will immediately cease and cause to be terminated any
                  existing solicitation, initiation, encouragement, activity,
                  discussion or negotiations with any parties conducted
                  heretofore by PVY or any of its representatives with respect
                  to any Business Combination.

             (2)  Except as expressly permitted by this Section 6.1(h), neither
                  the PVY Board of Directors nor any committee thereof may, (i)
                  withdraw or modify, or propose publicly to withdraw or
                  modify, in a manner adverse to SUG, the approval or
                  recommendation by such Board of Directors or such committee
                  of the Merger or this Agreement, (ii) approve or recommend,
                  or propose publicly to approve or recommend, a Business
                  Combination or (iii) cause PVY to enter into any letter of
                  intent, agreement in principle, acquisition agreement or
                  other similar agreement related to any Business Combination.
                  Notwithstanding the foregoing, prior to the time at which the
                  PVY Shareholders' Approval has been obtained, in response to
                  an unsolicited Business Combination proposal from a third
                  party, if PVY's Board of Directors determines, in its good
                  faith judgment, after consultation with and the receipt of
                  the advice of its financial advisor and outside counsel with
                  customary qualifications, that such proposal is a Superior
                  Proposal and that failure to do any of the actions set forth
                  in clauses (i), (ii) or (iii) above would create a reasonable
                  possibility of a breach of the fiduciary duties of PVY's
                  Board of Directors under applicable law, PVY's Board of
                  Directors may withdraw or modify its approval or
                  recommendation of the Merger or this Agreement, approve or
                  recommend a Business Combination or cause PVY to enter into a
                  Business Combination or an agreement related to a Business
                  Combination and, subject to PVY having paid to SUG the fees
                  described in Section 8.3(a) hereof and having entered into a

                  give SUG at least two (2) business days' notice thereof, and
                  shall cause its Representatives to, negotiate with SUG to
                  make such adjustments in the terms and conditions of this

                  PROVIDED, FURTHER, that if PVY and SUG are unable to reach an
                  agreement on such adjustments within two (2) business days
                  after such notice from PVY, PVY may enter into such
                  definitive agreement, subject to the provisions of Article
                  VIII.

             (3)  PVY shall notify SUG orally and in writing of any such
                  inquiries, offers or proposals (including the material terms
                  and conditions of any such offer or proposal and the identity
                  of the Person making it), within two business days of the

                  financial advisors and outside counsel, is financially
                  superior to the transactions contemplated hereby and it
                  appears that the party making the proposal is reasonably

                  Combination.

    (i) SOLICITATION OF PROXIES. Subject to Section 6.1(h), PVY shall use its
        reasonable best efforts to solicit from its shareholders proxies in

        to approve the ProvGas Merger and the Attleboro Merger.

    (j) PVY SHAREHOLDERS' APPROVAL.

             (1)  Subject to the provisions of Section 6.1(h) and Section

                  Statement in accordance with applicable federal and state law
                  and with its Organizational Documents, (iii) subject to the
                  fiduciary duties of its Board of Directors, recommend to its
                  shareholders the approval of this Agreement and the
                  transactions contemplated hereby and (iv) cooperate and
                  consult with SUG with respect to each of the foregoing
                  matters.

             (2)  The PVY Meeting for the purpose of securing the PVY
                  Shareholders' Approval, including any adjournments thereof,

        practicable, with SUG's requests with respect to refinancing by the
        Acquired Companies of the current maturities of any of their
        indebtedness, and any repurchase, redemption or prepayment by any of
        the Acquired Companies of any of its indebtedness or preferred stock
        that may be required because of the Mergers or that SUG may request
        that the Acquired Companies effect, so as to permit SUG to have the
        maximum opportunity to refinance, on or promptly after the Closing Date
        without any penalty except as may be due pursuant to the terms of the
        Acquired Companies' indebtedness and preferred stock as in effect on
        the date of this Agreement, any of the Acquired Companies' indebtedness
        or preferred stock outstanding on the Closing Date; PROVIDED, HOWEVER,
        that, except as provided in Section 6.1(m), no Acquired Company shall
        be required to consummate prior to the Effective Time any such
        refinancing, repurchase, redemption or repayment requested by SUG.

    (l) PVY DISCLOSURE SCHEDULE. On the date hereof, PVY has delivered to SUG
        the PVY Disclosure Schedule, accompanied by a certificate signed by an
        executive officer of PVY stating the PVY Disclosure Schedule is being

        constitutes an integral part of this Agreement and modifies the
        representations, warranties, covenants or agreements of PVY contained
        herein to the extent that such representations, warranties, covenants
        or agreements expressly refer to the PVY Disclosure Schedule; provided
        that (i) terms used in the PVY Disclosure Schedule, unless otherwise
        defined, shall have the meanings, if any, ascribed to them in this
        Agreement, (ii) information provided in one section of the PVY
        Disclosure Schedule shall suffice, without repetition or
        cross-reference, as a disclosure of such information in any other
        relevant section of the PVY Disclosure Schedule if the disclosure in
        the first section is sufficient on its face without further inquiry to
        reasonably inform SUG of the information required to be disclosed in
        such other sections of the PVY Disclosure Schedule in order to avoid a
        breach under the counterpart sections of this Agreement and (iii) the
        inclusion of any item in the PVY Disclosure Schedule shall not
        establish any threshold of materiality.

    (m) REDEMPTION OF PROVGAS PREFERRED STOCK. PVY shall cause ProvGas (i) to
        redeem 16,000 shares of ProvGas Preferred Stock on February 15, 2000
        pursuant to Section 4 of the Certificate of Authorization for the
        ProvGas Preferred Stock, and (ii) to redeem the remaining 16,000 shares

        such Certificate of Authorization.

    (n) AMENDMENT OF PROVGAS INDENTURE. PVY shall cause ProvGas to use its good
        faith commercially reasonable efforts to obtain prior to the Effective
        Time the consent of holders of at least 80% in aggregate principal
        amount of all First Mortgage Bonds outstanding under the ProvGas
        Indenture to each of the amendments to the ProvGas Indenture described
        on Schedule 6.1(n) hereto; PROVIDED, HOWEVER, that PVY and its
        Subsidiaries shall not be required to make

                                    C-23

<PAGE>

        any payment to any holder of First Mortgage Bonds prior to the
        Effective Time, other than such payments that are required to be made
        under the ProvGas Indenture, which payments ProvGas shall make as
        required under the ProvGas Indenture. If this Agreement is terminated
        and the Mergers do not occur, (i) within 30 days after the termination
        of this Agreement, PVY shall provide SUG with a schedule showing the
        reasonable out-of-pocket fees and reasonable out-of-pocket expenses,
        including fees and expenses of a solicitation agent, an information
        agent, and legal fees and expenses, incurred by or on behalf of PVY
        and ProvGas in connection with complying with the covenant set forth
        in the preceding sentence (excluding payments made to holders of the
        First Mortgage Bonds), (ii) within 30 days after the termination of
        this Agreement, SUG shall provide PVY with a schedule showing the

        connection with the solicitation of consents described in the
        preceding sentence (excluding payments made to holders of the First
        Mortgage Bonds), (iii) if PVY's fees and expenses, as set forth on the
        schedule provided by PVY pursuant hereto, exceed SUG's fees and
        expenses, as set forth on the schedule provided by SUG pursuant
        hereto, SUG shall pay PVY 50% of such excess within 60 days after the
        termination of this Agreement, and (iv) if SUG's fees and expenses, as
        set forth on the schedule provided by SUG pursuant hereto, exceed
        PVY's fees and expenses, as set forth on the schedule provided by PVY
        pursuant hereto, PVY shall pay SUG 50% of such excess within 60 days
        after the termination of this Agreement; PROVIDED, HOWEVER, that if
        this Agreement is terminated based on the breach by any party of its
        obligations under this Agreement, such breaching party shall bear its
        own such fees and expenses and shall pay the non-breaching party the
        fees and expenses, as set forth on the applicable schedule provided in
        accordance with this section by the non-breaching party, within 60
        days after the termination of this Agreement.

SECTION 6.2 COVENANTS OF SUG. SUG agrees to observe and perform the following
covenants and agreements:

    (a) GOVERNMENTAL APPROVALS; THIRD PARTY CONSENTS. SUG will use its
        commercially reasonable best efforts at SUG's sole expense to obtain
        all necessary consents, approvals and waivers from any Person required
        in connection with the transactions contemplated hereby under any
        license, lease, permit, Contract or agreement applicable to SUG,
        including, without limitation, the approvals of those Governmental
        Bodies listed in Section 4.3 of the SUG Disclosure Schedule and as
        required by the HSR Act.

    (b) EMPLOYEES; BENEFITS. With respect to the employees of the Acquired
        Companies (excluding unionized employees) (the "Employees"), except as
        otherwise specified herein, SUG agrees as follows:

             (1)  To assume and maintain for their term all employment and
                  change in control agreements of PVY in effect as of the
                  Effective Time;

             (2)  During the 24 months immediately following the Closing Date,
                  to maintain for the Employees who continue their service with
                  SUG or any Subsidiary of SUG base salary levels, bonus
                  opportunity levels and overall employee benefits (other than
                  the 1989 Stock Option Plan, the 1989 Non-Employee Director
                  Stock Option Plan, the Non-Employee Director Stock Plan, the
                  1998 Performance Share Plan, the Restricted Stock Incentive
                  Plan and the Employee Stock Purchase Plan, all of which shall
                  be terminated as of the Closing Date) that are no less
                  favorable in the aggregate than those currently provided to
                  Employees generally, except for any changes made to comply
                  with applicable law or tax qualification nondiscrimination
                  rules; provided, however, that (i) during such 24-month
                  period, all PVY qualified and non-qualified defined benefit
                  pension plans shall be maintained without adverse amendment
                  or modification, except for any changes made to comply with
                  applicable law or, in the case of the PVY tax-qualified
                  defined benefit plan, tax qualification nondiscrimination
                  rules; and (ii), with respect to any severance from
                  employment occurring during such 24-month period, to provide
                  severance benefits to such Employees on a basis no less
                  favorable than would otherwise be provided to such Employees
                  under the applicable severance pay plans of PVY as in effect
                  on the date of this Agreement. After the 24 months
                  immediately following the Closing Date, SUG agrees to
                  maintain during the next 24-month period, for Employees who
                  continue their service with SUG or any Subsidiary of SUG,
                  base salary levels, bonus opportunity and overall employee
                  benefits that are appropriate for the market given SUG's
                  financial circumstances, the industry in which it operates,
                  and regulatory considerations. Nothing in this Agreement
                  shall restrict, limit or interfere with the ability (after
                  the Closing Date) of SUG to terminate, amend or

                                    C-24

<PAGE>

                  replace any particular agreement, plan or program, or
                  terminate the employment of any person, provided that the
                  requirements of this Section 6.2(b)(2) are otherwise
                  satisfied.

             (3)  For purposes of eligibility, vesting and benefit accrual
                  under all benefit plans provided to the Employees after the
                  Closing Date, SUG will recognize the tenure of employment, as
                  recognized by the Acquired Companies as of the Closing Date.

             (4)  All vacation time earned by the Employees prior to the
                  Closing Date must be taken by the end of the calendar year in
                  which the Closing Date occurs, except where the Employee is
                  requested by PVY or SUG to forego their vacation for
                  business-related reasons. For purposes of awarding vacation
                  time at the beginning of each calendar year following the
                  Closing Date, SUG will recognize the tenure of employment, as
                  recognized by the Acquired Company as of the Closing Date.

             (5)  SUG will permit each of the Employees to carry forward all
                  days of sick leave accrued prior to the Closing Date.

             (6)  Effective immediately following the Closing Date, each
                  Employee who satisfies the eligibility criteria used by SUG
                  for similarly situated employees of SUG shall be eligible for
                  awards under SUG's Long-Term Incentive Stock Option Plan. SUG
                  represents that, as of the date of this Agreement, such plan
                  is the only plan in which SUG employees actively participate
                  which provides benefits in the form of SUG capital stock,
                  other than the SUG Employee Stock Purchase Plan or SUG
                  tax-qualified or supplemental retirement plans.

             (7)  For a five (5) year period from the Closing Date, SUG agrees
                  to provide retiree medical plan coverage which is
                  substantially comparable to the coverage under the PVY
                  retiree medical plan as of the date hereof, subject to SUG's
                  right to adjust copayment and cost sharing provisions (which
                  may be continued in the same proportions to the PVY-provided
                  portions of cost) to any former Employee (and his or her
                  eligible dependents) who is currently receiving such benefits
                  thereunder, or any active Employee (and his or her eligible
                  dependents) who would be eligible for such benefits if he or
                  she retired on the Closing Date (or who, within five (5)
                  years of the Closing Date, retires and is eligible to receive
                  benefits thereunder).

    (c) WARN. Neither SUG nor any Acquired Company shall, at any time prior to
        90 days after the Effective Time, effectuate a "plant closing" or "mass
        layoff," as those terms are defined in the Worker Adjustment and
        Retraining Notification Act of 1988, as amended ("WARN"), affecting in
        whole or in part any site of employment, facility, operating unit or
        employee without complying with the notice requirements and other
        provisions of WARN.

    (d) DIRECTORS. Immediately after the Effective Time on the Closing Date,
        the Chief Executive Officer of PVY immediately prior to the Effective
        Time shall be elected to the Board of Directors of SUG, and thereafter
        nominated and recommended for reelection if necessary such that such
        individual shall have a term of at least three years from the Closing
        Date, and such individual shall hold office in accordance with the
        Certificate of Incorporation and Bylaws of SUG; PROVIDED, HOWEVER, that
        if such individual is also an officer or employee of SUG, such
        individual shall be required to resign as a director of SUG if he
        resigns or is terminated as an officer or employee of SUG.

        that SUG will not be required to maintain such Rhode Island offices as
        the principal executive offices for all of SUG's energy-related

        Schedule constitutes an integral part of this Agreement and modifies

        otherwise defined, shall have the meanings, if any, ascribed to them in
        this Agreement, (ii) information provided in one section of the SUG
        Disclosure Schedule shall suffice, without repetition or
        cross-reference, as a disclosure of such information in any other
        relevant section of the SUG Disclosure Schedule if the disclosure in
        the first section is sufficient on its face without further inquiry to
        reasonably inform PVY of the information required to be disclosed in
        such other sections of the SUG Disclosure Schedule in order to avoid a
        breach under the counterpart sections of this Agreement and (iii) the
        inclusion of any item in the SUG Disclosure Schedule shall not
        establish any threshold of materiality.

SECTION 6.3   ADDITIONAL AGREEMENTS.

        shall take such reasonable steps as are necessary for the prompt
        preparation and filing with the SEC of a proxy statement relating to
        the PVY Meeting (together with any amendments thereto or supplements
        thereto, the "Proxy Statement"). Each of SUG and PVY shall furnish all
        information concerning it, its officers and directors, and the holders
        of its capital stock as the other may reasonably request in connection
        with the preparation and filing of the Proxy Statement. PVY will use
        all commercially reasonable efforts to cause the Proxy Statement to be
        cleared by the SEC as promptly as practicable after filing and as
        promptly as practicable after such clearance, PVY shall mail the Proxy
        Statement to its stockholders entitled to notice of and to vote at the
        PVY Meeting. As promptly as practical after consultation between SUG
        and PVY, PVY shall respond to any comments made by the SEC with respect
        to the Proxy Statement.

              (ii) The information supplied by PVY for inclusion or
                   incorporation by reference in the Proxy Statement shall not,
                   at the date of the mailing of the Proxy Statement (or any
                   supplement thereto) and at the time of the PVY Meeting,
                   contain any untrue statement of a material fact or omit to
                   state any material fact required to be stated therein or
                   necessary in order to make the statements therein, in the
                   light of the circumstances under which they were made, not
                   misleading. If at any time prior to PVY Meeting any event or
                   circumstance relating to PVY or any of its Subsidiaries, or
                   its or their respective officers or directors, should be
                   discovered by PVY that should be set forth in a supplement to
                   the Proxy Statement, PVY shall promptly inform SUG. All
                   documents that PVY is responsible for filing with the SEC in
                   connection with the transactions contemplated herein shall
                   comply as to form in all material respects with the
                   applicable requirements of the Securities Act and the
                   regulations thereunder and the Exchange Act and the
                   regulations thereunder.

              (iii)The information supplied by SUG for inclusion or
                   incorporation by reference in the Proxy Statement shall not,
                   at the date of the mailing of the Proxy Statement (or any
                   supplement thereto), at the time of the PVY Meeting, contain
                   any untrue statement of a material fact or omit to state any
                   material fact required to be stated therein or necessary in
                   order to make the statements therein, in the light of the
                   circumstances under which they are made, not misleading. If
                   at any time prior to the PVY Meeting any event or
                   circumstance relating to SUG or any of its Subsidiaries, or
                   to their respective officers or directors, should be
                   discovered by SUG that should be set forth in a supplement to
                   the Proxy Statement, SUG shall promptly inform PVY.

              (iv) No representation, warranty, covenant or agreement is made by
                   or on behalf of PVY with respect to information supplied by
                   any other Person for inclusion in the Proxy Statement. No
                   representation, warranty, covenant or agreement is made by or
                   on behalf of SUG with respect to information supplied by any
                   other Person for inclusion in the Proxy Statement. No filing
                   of, or amendment or supplement to, the Proxy Statement shall
                   be made by PVY without providing SUG with the opportunity to
                   review and comment thereon (except for any ongoing SEC
                   reporting required of PVY or ProvGas that will be
                   incorporated by reference). If at any time prior to the PVY
                   Meeting any information relating to any party hereto or any
                   of their respective officers, directors, shareholders or
                   Subsidiaries, should be discovered by any party hereto which
                   should be set forth in an amendment or supplement to the
                   Proxy Statement so that the Proxy Statement would not include
                   any untrue statement of a material fact or omit to state any
                   material fact necessary to make the statements therein, in
                   light of the circumstances under which they were made, not
                   misleading, the party which discovers such information shall
                   promptly notify the other party hereto and an appropriate
                   amendment or supplement describing such information shall be
                   promptly prepared, filed with the SEC and, to the extent
                   required by law, disseminated to the shareholders of PVY.

     (b) FURTHER ASSURANCES. Each of SUG and PVY agrees, and PVY agrees to cause
         its Subsidiaries, to take all such reasonable and lawful action as may
         be necessary or appropriate in order to effectuate the Mergers in
         accordance with this Agreement as promptly as possible. If, at any time
         after the Effective Time, any such further action is necessary or
         desirable to carry out the purpose of this Agreement and to vest SUG
         with full right, title and possession to all assets, property, rights,
         privileges, powers and franchises of the Acquired Companies, the
         officers and directors of SUG will be fully authorized to take, and
         will take, all such lawful and necessary action.

     (c) FINANCIAL STATEMENTS TO BE PROVIDED. Upon SUG's request, PVY shall (i)
         provide to SUG audited and unaudited financial statements required to
         be included in the proxy statements and the registration statement
         contemplated by the Agreement of Merger, dated as of October 4, 1999,
         by and between SUG and Fall River Gas Company and (ii) cause its
         independent accountants to deliver to SUG and Fall River Gas Company
         the required consents in connection therewith.

         of the RIBCA or MBCL, as the case may be; PROVIDED, HOWEVER, that such
