MASSACHUSETTS LAW REQUIRES THAT THE HOLDERS OF A MAJORITY OF FALL RIVER GAS
COMPANY'S OUTSTANDING COMMON STOCK BE PRESENT IN PERSON OR BY PROXY AT THE

The accompanying proxy, to be mailed to Fall River Gas Company ("Fall River
Gas") stockholders together with the Notice of Special Meeting and this proxy
statement/prospectus on or about July 12, 2000, is solicited by Fall River Gas
in connection with the special meeting to be held on August 29, 2000.

                     QUESTIONS AND ANSWERS ABOUT THE MERGER

Q:   WHAT WILL HAPPEN TO FALL RIVER GAS AS A RESULT OF THE MERGER?

A:   If the merger is completed, Fall River Gas will merge into Southern Union
     Company ("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.

Q:   WHAT DO I NEED TO DO NOW?

A:   After you carefully read and consider the information contained in this
     document, please indicate on the enclosed proxy card how you want to vote.
     Sign and mail 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 agreement.

Q:   WHAT IS THE REQUIRED VOTE TO APPROVE AND ADOPT THE MERGER AGREEMENT?

A:   The merger agreement must be approved and adopted by the holders of at
     least two-thirds of the shares of Fall River Gas common stock entitled to
     vote at the special meeting.

Q.   WHAT WILL YOU RECEIVE IF THE MERGER IS COMPLETED?

A.   You will have the option to elect either cash or Southern Union common
     stock or a combination of both in exchange for your shares. You may elect
     to receive either $23.50 in cash for each share you own or a number of
     shares of Southern Union common stock equal to an exchange ratio. The
     exchange ratio will be adjusted shortly before the closing of the merger
     to ensure that the value of the Southern Union common stock you receive,
     for each share of Fall River Gas common stock you own, will be
     approximately $23.50. This election is subject to the limitation that no
     more than 50% of the aggregate consideration paid to all Fall River Gas
     stockholders may be in cash.

     Please read the more detailed description of the consideration to be
     issued in the merger on pages 48 through 50.

Q.   WILL I ALWAYS RECEIVE THE SPECIFIC AMOUNTS OF CASH AND STOCK THAT I HAVE
     ELECTED?

A:   If you elect stock consideration, you will receive the amount of whole
     shares of Southern Union common stock you elected and you will get cash
     for any fractional shares that you would otherwise receive. However, if
     you elect cash, the amount of cash you receive as consideration in the
     merger may be less than the amount you actually elected if too many other
     Fall River Gas stockholders elect cash. If the Fall River Gas
     stockholders as a whole exceed the cash limitation, the amount of cash
     paid to each stockholder electing cash will be reduced proportionately.

     Please read the more detailed description of the consideration to be
     issued in the merger on pages 48 through 50.

Q:   WHO IS ENTITLED TO VOTE?

                                       1

<PAGE>

A:   Stockholders as of the close of business on the record date, July 5, 2000
     are entitled to vote at the special meeting.

Q:   CAN I CHANGE MY VOTE AFTER I HAVE MAILED IN MY SIGNED PROXY CARD?

A:   Yes. You may change your vote at any time before the vote takes place at
     the special meeting. To do so, you can attend the special meeting and vote
     in person. Or, you can complete a new proxy card or send a written notice
     stating you would like to revoke your proxy. These should be sent to: Fall
     River Gas Company, 155 North Main Street, P.O. Box 911, Fall River,
     Massachusetts 02722-0911, Attention: Clerk. This notice must reach the
     Clerk before the proxy is voted.

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

A:   A broker will vote your shares on the merger agreement 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.   AM I ENTITLED TO STATUTORY APPRAISAL RIGHTS?

A:   No, Fall River Gas stockholders are not entitled to appraisal rights under
     Massachusetts law.

Q:   SHOULD I SEND IN MY CERTIFICATES NOW?

A:   No. After the merger is completed, Southern Union will send written
     instructions to you for exchanging your stock certificates. YOU SHOULD NOT
     SEND IN YOUR STOCK CERTIFICATES WITH YOUR PROXY.

Q:   WHO CAN HELP ANSWER MY QUESTIONS?

A:   If you have any questions about the merger or if you need additional
     copies of this document or the enclosed proxy, you should contact Peter
     H. Thanas, Senior Vice President and Treasurer, Fall River Gas Company,
     155 North Main Street, P.O. Box 911, Fall River, Massachusetts 02722.

Q:   WHEN IS THE MERGER EXPECTED TO BE COMPLETED?

A:   Fall River Gas and Southern Union are working as quickly as possible and
     hope to complete the merger in September 2000.

                                    OVERVIEW

Southern Union and Fall River Gas entered into a merger agreement on October
4, 1999. We are asking you to approve this merger agreement. The merger
agreement sets forth the terms and conditions and the details of the
transactions through which Southern Union proposes to acquire Fall River Gas.
Under the terms of

                                       5

<PAGE>

the merger agreement, at the closing, each outstanding share of Fall River Gas
common stock will be converted into the right to receive either $23.50 in cash
or a number of shares of Southern Union common stock equal to an exchange
ratio that will be adjusted shortly before the closing of the merger to ensure
that the value of Southern Union common stock received for each share of Fall
River Gas common stock will be approximately $23.50, or a combination of both,
depending on each Fall River Gas stockholder's election. At least 50% of all
outstanding shares of Fall River Gas must be exchanged for shares of Southern
Union common stock.

Upon completion of the transactions contemplated by the merger agreement, Fall
River Gas will be merged into Southern Union and its utility business will be
operated as a division of Southern Union. Fall River Gas' non-regulated
subsidiary will become a subsidiary of Southern Union.

                                  THE COMPANIES

natural gas divisions in Texas, Missouri, Pennsylvania, and Florida; its
propane distribution subsidiaries; and its equity ownership in a natural gas

                                   THE MERGER

SUMMARY (SEE PAGE 48)

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. When we
speak about

                                       6

<PAGE>

the "merger" and the "merger agreement" in this proxy statement/prospectus, we
mean the merger of Fall River Gas into Southern Union and the agreement that
sets forth the details of that merger.

                                       7

<PAGE>

The merger will become effective following the 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 is attached at the back of this proxy
statement/prospectus as Appendix A. We encourage you to read the merger
agreement since it is the legal document that governs the merger.

WHAT HOLDERS OF FALL RIVER GAS COMMON STOCK WILL RECEIVE IN THE MERGER (SEE
PAGE 48)

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

Each share of your Fall River Gas common stock that you elect 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 your Fall River Gas common stock that you 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, you will get cash for any fractional
shares of Southern Union common stock you would otherwise receive.

You will be entitled to receive Southern Union common stock in the merger if:

-    you elect to receive Southern Union common stock;

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

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

-    you do not properly complete the form of election provided to you 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 you will receive for
each share of Fall River Gas common stock that you own 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

                                       8

<PAGE>

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, you
     will receive 1.39259 shares of Southern Union common stock per share of
     Fall River Gas common stock.

PROCEDURE FOR FILING ELECTIONS AND CONVERTING FALL RIVER GAS COMMON STOCK INTO
MERGER CONSIDERATION (SEE PAGE 50)

A form of election and complete instructions for properly making an election
to receive either cash or Southern Union common stock or a combination of cash
and Southern Union common stock will be delivered under separate cover to
holders of record of shares of Fall River Gas (as of a record date as close as
practicable to the date of mailing) at least 15 business days prior to the
anticipated closing date of the merger. The closing date of the merger is
expected to occur in September 2000.

Fall River Gas stockholders will be entitled to choose one of the following
consideration options, which will be listed on their form of election:

-    to receive cash for each share of Fall River Gas they own;

-    to receive Southern Union common stock for each share of Fall River Gas
     they own;

-    to exchange some of their shares of Fall River Gas for cash and some for
     Southern Union common stock; or

-    to indicate no preference as to type of consideration.

You will be eligible to receive cash only if the paying agent has received a
properly completed form of election at its designated office or offices by
4:00 p.m., Eastern Time, on the third business day prior to the closing date
of the merger. You will be eligible to receive as consideration only shares of
Southern Union common stock if:

                                       9

<PAGE>

-    the form of election you submit indicates a preference to receive only
     shares of Southern Union common stock;

-    the form of election you submit indicates no preference as to form of
     consideration; or

-    you fail to submit a properly completed form of election prior to the
     deadline for submitting cash elections.

You may revoke your election only if Southern Union's paying agent receives
written notice of revocation prior to the deadline for submitting cash
elections.

CERTAIN FEDERAL INCOME TAX CONSEQUENCES (SEE PAGE 42)

In regard to the Southern Union common stock and cash received in the merger,
a Fall River Gas stockholder will generally recognize capital gain for U.S.
federal income tax purposes in an amount equal to the lesser of (i) the amount
of cash received or (ii) the excess of the amount of cash and the fair market
value of Southern Union common stock received in the merger over the tax basis
of the Fall River Gas common stock surrendered.

The merger will not result in the recognition of gain or loss to Southern
Union or Fall River Gas.

SINCE THE TAX CONSEQUENCES OF THE MERGER TO YOU MAY VARY DEPENDING UPON YOUR
PARTICULAR CIRCUMSTANCES AS A FALL RIVER GAS STOCKHOLDER, YOU SHOULD CONSULT
YOUR OWN TAX ADVISORS REGARDING THE FEDERAL (AND ANY STATE, LOCAL OR FOREIGN)
TAX CONSEQUENCES OF THE MERGER IN LIGHT OF YOUR PARTICULAR CIRCUMSTANCES.

RECOMMENDATION TO FALL RIVER GAS COMMON STOCKHOLDERS (SEE PAGE 34)

The Fall River Gas board of directors believes that the merger is in the best
interest of Fall River Gas stockholders and recommends that holders of Fall
River Gas common stock vote "FOR" the approval and adoption of the merger
agreement. The reasons for the board's recommendation are set forth on pages
34 to 36.

FAIRNESS OPINION OF FALL RIVER GAS' FINANCIAL ADVISOR (SEE PAGE 36)

In deciding to approve the merger, the Fall River Gas board of directors
considered an opinion from its financial advisor Legg Mason Wood Walker,
Incorporated ("Legg Mason") to the effect that, as of the date of the merger
agreement, the consideration to be received by Fall River Gas stockholders was
fair to the stockholders from a financial point of view. This opinion is
attached as Appendix B to this proxy statement/prospectus. We encourage you to
read this opinion.

                       THE FALL RIVER GAS SPECIAL MEETING

                                      10

<PAGE>

The Fall River Gas special meeting will be held at 10:00 a.m. (Eastern Time)
on August 29, 2000, at the office of Fall River Gas, 155 North Main Street,
Fall River, Massachusetts 02722. At the meeting, holders of Fall River Gas
common stock will be asked to approve and adopt the merger agreement.

RECORD DATE; VOTING RIGHTS; VOTING AGREEMENT (SEE PAGE 29)

If you owned shares of Fall River Gas common stock as of the close of business
on July 5, 2000, you are entitled to vote at the special meeting.

On that date, there were 2,252,429 shares of Fall River Gas common stock
outstanding. Holders of Fall River Gas common stock will have one vote at the
special meeting for each share of Fall River Gas common stock they own on that
date.

In connection with the merger, Barbara N. Jarabek, as trustee to 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 entered into a voting agreement with Southern Union. According to the
terms of the voting agreement, these stockholders: 1) agreed to vote or cause
to be voted their shares of Fall River Gas common stock in favor of the merger
and the adoption and approval of the merger agreement, and 2) granted Southern
Union an irrevocable proxy to vote their shares of Fall River Gas common stock
for the approval and adoption of the merger agreement and the performance of
transactions related to the merger. As of the special meeting record date, the
number of shares beneficially owned by the Fall River Gas stockholders who
entered into the voting agreement and granted this irrevocable proxy
represented approximately 25.6% of the outstanding shares of Fall River Gas
common stock entitled to vote on the approval and adoption of the merger
agreement and performance of transactions related to the merger agreement.

Of the 572,510 shares of Fall River Gas common stock represented by the
stockholders who are parties to the voting agreement, as of May 31, 2000,
276,800 shares were beneficially owned by executive officers and directors of
Fall River Gas. The voting agreement is attached as Appendix C to this proxy
statement/prospectus. See "The Merger Agreement - Covenants and other
Agreements - Fall River Gas Voting Agreement."

As of the close of business on May 31, 2000, directors and officers of Fall
River Gas beneficially owned and were entitled to vote approximately 297,216
shares of Fall River Gas common stock, which represented approximately 13.3%
of the shares of Fall River Gas outstanding on that date. Each of them has
indicated his or her present intention to vote, or cause to be voted, the Fall
River Gas common stock owned by him or her for the proposal to approve and
adopt the merger agreement.

QUORUM; REQUIRED VOTE (SEE PAGE 29)

A majority of the shares of Fall River Gas 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.

                                      11

<PAGE>

Consummation of the merger requires the approval of at least two-thirds of the
shares of Fall River Gas outstanding and entitled to vote at the meeting.

If you hold your shares of Fall River Gas 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 APPROVAL AND
ADOPTION OF THE MERGER AGREEMENT.

                      SUMMARY OF OTHER SELECTED INFORMATION

POTENTIAL CONFLICTS AND INTERESTS OF OFFICERS AND DIRECTORS IN THE MERGER (SEE
PAGE 40)

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 interest of Fall
River Gas stockholders generally and may represent conflicts of interest.

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 merger is completed. On
October 4, 1999, these employment agreements were amended. These amendments
will become effective as of the date the 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 Messrs. Faxon, Thanas
and Fanning continue 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, in
certain circumstances.

For six years after the 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.

The Fall River Gas board was aware of these interests and considered them in
approving the merger agreement.

REGULATORY APPROVALS (SEE PAGE 44)

Certain approvals from the state regulatory commissions of Massachusetts,
Missouri and Pennsylvania, 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.
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 merger is also required. As of the date of this
proxy statement/prospectus, only the required regulatory approvals from the
Missouri and Pennsylvania commissions for the merger have been obtained.

                                      12

<PAGE>

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 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 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 has advised Fall
River Gas and the Massachusetts Department of Telecommunications and Energy
that it intends to seek, and through its proxy is seeking, such stockholder
approval at the Southern Union special meeting.

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 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 directors and executive officers other than the Lindemanns, discussed
above, beneficially owned and were entitled to vote approximately 5% of the
shares of Southern Union common stock outstanding. Together with the
Lindemanns, this represents a total of approximately 32% of the shares of
Southern Union common stock outstanding as of June 30, 2000.

CONDITIONS TO THE MERGER (SEE PAGE 59)

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

-    Approval by Fall River Gas stockholders.

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

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

-    Effectiveness of the registration statement in which this proxy
     statement/prospectus is included.

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

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

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

TERMINATION OF THE MERGER AGREEMENT AND TERMINATION FEES (SEE PAGE 61 AND PAGE
62)

Fall River Gas and Southern Union may terminate the merger agreement by mutual
written consent without completing the merger. The 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 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.

COMPARATIVE STOCKHOLDER RIGHTS (SEE PAGE 77)

When the merger is completed, a holder of Fall River Gas common stock, to the
extent he has not received cash in exchange for any or all of his shares, will
be a stockholder of Southern Union. The rights of these stockholders will be
governed by Delaware law and Southern Union's restated certificate of
incorporation and bylaws (instead of Massachusetts law and Fall River Gas'
articles of organization and bylaws), subject to any continuing application of
any Massachusetts law provisions as a result of Southern Union becoming a
Massachusetts utility. Certain differences between the rights of holders of
Southern Union common stock and those of holders of Fall River Gas common
stock are summarized on pages 77 to 88.

ACCOUNTING TREATMENT (SEE PAGE 46)

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

(a)  Certain Texas and Oklahoma Panhandle distribution operations and Western
     Gas Interstate (a former subsidiary of Southern Union), exclusive of the
     Del Norte interconnect, were sold on May 1, 1996.
(b)  On December 31, 1997, Southern Union acquired Atlantic Utilities
     Corporation and Subsidiaries for 755,650 pre-split and pre-stock dividend
     shares of common stock valued at $18,041,000 and cash of $4,436,000.
(c)  PEI was acquired on November 4, 1999 and was accounted for as a purchase.
     PEI's assets are included in the Company's consolidated balance sheet at
     March 31, 2000 and its results of operations have been included in the
     Company's consolidated results of operations since November 4, 1999. For
     these reasons, the consolidated results of operations of the company for
     the periods subsequent to the acquisition are not comparable to the same
     periods in prior years.
(d)  As of June 30, 1998, Missouri Gas Energy (a division of Southern Union)
     wrote off $8,163,000 pre-tax in previously recorded regulatory assets as a
     result of announced rate orders and court rulings.
(e)  Earnings per share for all periods presented were computed based on the
     weighted average number of shares of common stock and common stock
     equivalents outstanding during the year adjusted for (i) the 5% stock
     dividends distributed on June 30, 2000, August 6, 1999, December 9, 1998,
     December 10, 1997, December 10, 1996 and November 27, 1995, and (ii) the

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 assumption 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").

The selected unaudited pro forma combined condensed financial data as of and for
the year ended June 30, 1999, and as of and for the nine months ended March 31,
2000, were derived from and should be read in conjunction with the Unaudited Pro
Forma Combined Condensed Balance Sheet and the Unaudited Pro Forma Combined
Condensed Statement of Operations, including the notes thereto, which are

</TABLE>

(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 stockholders 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 ValleyResources.

<PAGE>

                      RISK FACTORS AND OTHER CONSIDERATIONS

You should consider carefully all the information contained in this proxy
statement/prospectus, including the following matters:

THE AMOUNT OF CONSIDERATION RECEIVED IN STOCK MAY VARY AS A RESULT OF
FLUCTUATIONS IN SOUTHERN UNION'S STOCK PRICE

Fall River Gas stockholders may choose whether they want to exchange their Fall
River Gas common stock for either cash or Southern Union common stock. Fall
River Gas stockholders may also choose to exchange some of their Fall River Gas
common stock for cash and some for Southern Union common stock. The opportunity
to make this election will occur only shortly before the merger is completed,
which will be after the time of the Fall River Gas stockholder vote on the
merger. Also, the exchange ratio used to determine the amount of Southern Union
common stock to be delivered to Fall River Gas stockholders who are entitled to
receive Southern Union common stock will be adjusted. This adjustment will be
based on the average of the closing prices of Southern Union common stock on the
NYSE for a period of ten consecutive trading days ending on the third trading
day before the date that the merger is completed.

The adjustments to the exchange ratio are designed to ensure that the aggregate
value based on this average price of the Southern Union shares to be exchanged
for each share of Fall River Gas common stock you own will be at least $23.50
per share (except as explained in the second paragraph below) unless Fall River
Gas decides to complete the merger if the average price is below $15.00 a share.

You should be aware of two risks associated with these methods of electing the
form of merger consideration you want to receive and adjusting the amount of
Southern Union common stock to be delivered to Fall River Gas stockholders upon
completion of the merger.

-    First, there may be significant time lapses between: 1) when your vote is
     cast regarding the merger at the special meeting, 2) when you make your
     election regarding the form of merger consideration you want to receive,
     and 3) when merger is completed. During this period of time, the market
     value of Southern Union common stock may fluctuate significantly. At the
     time your vote is cast regarding approval of the merger and the time at
     which you make your election regarding the form of merger consideration you
     want to receive, you will not know the exact number of shares of Southern
     Union common stock that will be delivered to you when the merger is
     completed.

-    Second, the number of shares of Southern Union common stock you will
     receive will be based on the closing prices of Southern Union common stock
     from the twelfth to the third trading days before the date that the merger
     is completed. The actual market value of the shares when received by you
     will depend on the market value of a share of Southern Union common stock
     on that date, which may be less than the value used to determine the number
     of shares you will receive.

You are urged to obtain current market quotations for Southern Union common
stock and Fall River Gas common stock.


                                       19
<PAGE>

THE AMOUNT OF CASH PAID TO STOCKHOLDERS ELECTING CASH MAY BE REDUCED
PROPORTIONATELY

No more than 50% of the aggregate consideration paid to all Fall River Gas
stockholders may consist of cash. If you elect to receive cash in exchange for
some or all of your shares of Fall River Gas common stock, the amount of cash
you receive as consideration in the merger may be less than the amount you
actually elected because too many other Fall River Gas stockholders elected to
receive cash. If the Fall River Gas stockholders exceed their cash limitation,
the amount of cash paid to each stockholder electing cash will be reduced
proportionately.

THE COMBINED COMPANY MAY NOT REALIZE BENEFITS OF INTEGRATING OUR COMPANIES, THE
COMPANY SOUTHERN UNION RECENTLY ACQUIRED AND THE OTHER COMPANIES SOUTHERN UNION
HAS AGREED TO ACQUIRE

Southern Union recently acquired PEI and has agreed to acquire several
companies, including Fall River Gas. See "Recent Developments - Southern Union."
The combined company will need to combine and integrate the operations of these
separate companies into one company. The combined company could encounter
difficulties in the integration process, such as the loss of key employees,
customers or suppliers. If the combined company cannot integrate the businesses
of Southern Union and the other companies, successfully, the combined company
may fail to realize the benefits that Southern Union's and Fall River Gas'
management expect to realize from the merger.

APPROVALS MAY NOT BE OBTAINED OR MAY CONTAIN UNACCEPTABLE RESTRICTIONS

The consummation of the merger is conditioned upon receiving approval from
various governmental regulatory authorities. It is possible that some required
approvals and consents will not be obtained or that such approvals and consents
can be obtained only if they contain certain restrictions on the combined
company that will not be acceptable or would adversely affect the value of the
combined company. See "The Merger - Regulatory Matters." Required approvals that
have not yet been received are:

-    approval of the merger by the Massachusetts Department of
     Telecommunications and Energy;

-    authorization by the Florida Public Service Commission and the Pennsylvania
     Public Utility Commission of any securities issued by Southern Union in
     connection with the merger; and

-    expiration or termination of the applicable waiting period under the
     Hart-Scott-Rodino Antitrust Improvements Act of 1976.

In addition, other filings with, notifications to and authorizations and
approvals of various government agencies and third-party consents with respect
to the merger must be made or received before the completion of the merger. As
of the date of this proxy statement/prospectus, only the required approval of
the Pennsylvania and Missouri commissions for the merger have been obtained.
Fall River Gas and Southern Union are seeking to obtain all other required
approvals and consents, most of which will not be obtained prior to the Fall
River Gas special meeting.


                                       20
<PAGE>

FUTURE ACQUISITIONS MAY NOT ACHIEVE FAVORABLE FINANCIAL RESULTS, MAY DILUTE YOUR
PERCENTAGE OWNERSHIP IN SOUTHERN UNION OR REQUIRE SUBSTANTIAL EXPENDITURES

Southern Union's strategic plan is to increase the scale of its operations and
the size of its customer base by pursuing and consummating future business
combination transactions. Recently, it has acquired or agreed to acquire four
companies, including Fall River Gas. See "Recent Developments - Southern Union."
The combined company may not be able to consummate future acquisitions on
favorable terms. In addition, future acquisitions may not achieve favorable
financial results.

Future acquisitions may involve or require the issuance of shares of Southern
Union common stock, which could have a dilutive effect on the then-current
stockholders of Southern Union. Southern Union may not choose or be able to
acquire companies or assets associated with the energy industry using its equity
as currency. The combined company's leverage might be increased to finance an
acquisition or the operations of the combined company. Furthermore, acquisitions
may require substantial financial expenditures that will need to be financed
through cash flow from operations or future debt and equity offerings by the
combined company. Southern Union may not be able to generate sufficient cash
flow from operations or obtain debt or equity financing sufficient to fund
future acquisitions or the expenditures required because of the acquisitions.

A DIFFERENT SET OF FACTORS AND CONDITIONS AFFECT SOUTHERN UNION STOCK AND COULD
HAVE A NEGATIVE IMPACT ON ITS STOCK PRICE

Upon completion of the merger, stockholders of Fall River Gas that do not
receive cash for any or all of their shares of Fall River Gas stock will become
holders of Southern Union common stock. The businesses and markets of Southern
Union and the other companies it has acquired and is acquiring are different
from those of Fall River Gas. For example, the natural gas business of Fall
River Gas depends primarily on weather, economic and regulatory conditions
affecting southeastern Massachusetts. Southern Union's gas business depends in
part on weather and economic conditions in Texas, Missouri, Pennsylvania, and
Florida. In addition, Southern Union, through its subsidiaries, is engaged in
the electricity business and the propane distribution business.

There is a risk that various factors, conditions and developments which would
not affect the price of Fall River Gas' stock could negatively affect the price
of Southern Union's stock. See "Forward-Looking Statements May Prove Inaccurate"
for a summary of many of the key factors that might affect Southern Union and
the price at which Southern Union common stock may trade from time to time. See
"Comparative Per Share Data" for certain unaudited historical per share data of
Southern Union and Fall River Gas.

SOUTHERN UNION DOES NOT PAY CASH DIVIDENDS ON ITS COMMON STOCK

Fall River Gas presently pays a $0.24 quarterly cash dividend on its outstanding
shares of common stock. Southern Union presently does not pay a cash dividend.
Southern Union plans to continue to distribute an annual 5% stock dividend,
subject to any required regulatory approvals being obtained.


                                       21

COMPETITION WITHIN THE NATURAL GAS INDUSTRY IS INTENSE

As a result of the deregulation of the utility industry, the natural gas
distribution business has become highly competitive. In a deregulated
environment, formerly regulated utility companies that are not responsive to a
competitive energy marketplace suffer erosion in market share, revenues and
profits as competitors gain access to their service territories.

Although the merger will result in a larger combined company with a more diverse
customer base, several of the combined company's competitors will still have
substantially larger financial resources, staffs and facilities than the
combined company. There is a risk that the intense competition for natural gas
customers may in the future reduce the combined company's earnings from retail
natural gas service and have an adverse effect on the stability of the combined
company's utility earnings generally.

THE TERMS OF MERGER-RELATED FINANCINGS MAY ADVERSELY AFFECT THE COMBINED COMPANY

Southern Union's management would require financing through external sources of
up to approximately $600 million to complete the pending mergers (assuming that
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 $140
million of existing long-term debt of the three companies being acquired must be
refinanced rather than amended and assumed as planned) necessary to fund the
total cash payable to the stockholders of Fall River Gas, ProvEnergy and Valley
Resources, and costs and refinancings related to all of these mergers in
connection with completion of these mergers (see "The Companies - Southern Union
- Acquisitions").

In addition to the Fall River Gas, ProvEnergy and Valley Resources transactions,
other future acquisitions may require substantial financial expenditures that
will also need to be financed through external sources, including future debt
and equity offerings by the combined company. Furthermore, Southern Union may
refinance a portion of the outstanding debt of Fall River Gas, ProvEnergy,
Valley Resources and their respective subsidiaries in connection with or soon
after the completion of those transactions.

Sources of financing for the three pending and any future acquisitions may
include commercial and investment banks, institutional lenders and investors,
and the public securities markets. Southern Union presently plans to fund the
pending mergers with bank borrowings, but has no commitments at this time. After
closing the mergers, Southern Union may need or choose to refinance some or all
of any bank financing for the mergers. The terms of any financing or refinancing
arrangements may contain covenants that could adversely affect the financial
condition and flexibility of the combined company. 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 financing on reasonable
terms and conditions.

                 FORWARD-LOOKING STATEMENTS MAY PROVE INACCURATE

We have each 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
     services and/or operating efficiencies;

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


                                       23
<PAGE>

-    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.

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/prospectus, or, in the case of
documents incorporated by reference, the dates of those documents.

                               RECENT DEVELOPMENTS

SOUTHERN UNION

In addition to the Fall River Gas merger, 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 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 PROVIDENCE ENERGY CORPORATION. On November 14, 1999, Southern Union
and ProvEnergy (NYSE: "PVY") entered into a definitive merger agreement. The
agreement calls for ProvEnergy and its utility subsidiaries to merge into
Southern Union in a transaction valued at approximately $400 million, including
the assumption of debt. ProvEnergy shareholders will receive $42.50 in cash for
each of the approximately 6.1 million shares of ProvEnergy common stock
outstanding. ProvEnergy, headquartered in Providence, Rhode Island, is engaged
through its subsidiaries principally in natural gas distribution to
approximately 168,000 natural gas customers in Providence and Newport, Rhode
Island, and 23 other cities and towns in Rhode Island and Massachusetts.
ProvEnergy's oil business serves over 4,000 residential customers and a large
commercial base. ProvEnergy's utility service territories encompass
approximately 760 square miles with a population of approximately 850,000. On
May 22, 2000, the shareholders of ProvEnergy approved the terms of the
ProvEnergy merger. Southern Union anticipates completing the ProvEnergy merger
in September 2000 once all remaining conditions are satisfied, including receipt
of all regulatory approvals.

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.

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 an 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 FALL RIVER GAS SPECIAL MEETING

PURPOSE, TIME AND PLACE

The special meeting will be held at the office of Fall River Gas, 155 Main
Street, Fall River, Massachusetts 02722 on August 29, 2000, at 10:00 a.m.
(Eastern Time), for the following purposes:

(1)  To approve and adopt the merger agreement;

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

RECORD DATE; VOTING POWER; VOTE REQUIRED

The Fall River Gas board has fixed the close of business on July 5, 2000 as the
record date for the determination of holders of Fall River Gas common stock
entitled to notice of and to vote at the special meeting. Fall River Gas common
stock, of which there were 2,252,429 shares outstanding and entitled to vote on
July 5, 2000, is the only class of securities of Fall River Gas entitled to vote
at the special meeting. A majority of the shares of Fall River Gas 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 Fall River Gas 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 Fall River Gas common stock outstanding on
the record date. The Fall River Gas board recommends that Fall River Gas
stockholders vote "FOR" approval and adoption of the merger agreement.

SHARE OWNERSHIP OF MANAGEMENT; MANAGEMENT VOTE; VOTING AGREEMENT

As of the close of business on May 31, 2000, directors and officers of Fall
River Gas beneficially owned and were entitled to vote approximately 297,216
shares of Fall River Gas common stock, which represented


                                       30
<PAGE>

approximately 13.3% of the shares of Fall River Gas outstanding on that date.
Each of them has indicated his or her present intention to vote, or cause to
be voted, the Fall River Gas common stock owned by him or her "FOR" the
proposal to approve and adopt the merger agreement at the special meeting.
See "Principal Stockholders - Beneficial Owners of More Than 5% of Fall River
Gas' Common Stock" and "Fall River Gas Management Ownership" for additional
information.

In connection with the merger, Barbara N. Jarabek, as trustee to 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
entered into a voting agreement with Southern Union. According to the terms of
the voting agreement, these stockholders agreed: 1) to vote or cause to be voted
their shares of Fall River Gas common stock in favor of the merger and the
adoption and approval of the merger agreement, and 2) to grant Southern Union an
irrevocable proxy to vote their shares of Fall River Gas common stock for the
approval and adoption by the Fall River Gas stockholders of the merger agreement
and the performance of transactions related to the merger. As of the special
meeting record date, the number of shares beneficially owned by the Fall River
Gas stockholders who entered into the voting agreement and granted this
irrevocable proxy represent approximately 25.6% of the outstanding shares of
Fall River Gas common stock entitled to vote on the approval and adoption of the
merger agreement and performance of transactions related to the merger
agreement.

Of the 572,510 shares of Fall River Gas common stock represented by the
stockholders who are parties to the voting agreement, as of May 31, 2000,
276,800 shares were beneficially owned by executive officers and directors of
Fall River Gas. The voting agreement is attached as Appendix C to this proxy
statement/prospectus. See "The Merger Agreement - Covenants and other
Agreements - Fall River Gas Voting Agreement."

VOTING OF PROXIES

All holders of Fall River Gas 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"
approval and adoption of the merger agreement.

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).
Fall River Gas 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

Massachusetts law provides that a proxy, unless coupled with an interest (for
example, a vote pooling or similar arrangement among holders of Fall River Gas
common stock, or between Fall River Gas and holders of Fall River Gas common
stock, or an unrevoked proxy in favor of an existing or potential creditor of a
holder of Fall River Gas common stock), is revocable at will by a holder of Fall
River Gas common stock,


                                       31
<PAGE>

notwithstanding any other agreement or provision in the proxy to the
contrary. A holder of Fall River Gas common stock may revoke a proxy by
giving written notice of revocation to the clerk of Fall River Gas at Fall
River Gas' address set forth on page 5 of this proxy statement/prospectus at
any time before the proxy is voted. Such revocation will be effective upon
receipt of the written notice by the Clerk of Fall River Gas.

SOLICITATION OF PROXIES

Fall River Gas and Southern Union will each bear half of 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 Fall River Gas may reimburse them for
their expenses in so doing. To the extent necessary in order to ensure a
sufficient presence of holders of Fall River Gas common stock to constitute a
quorum, officers and other employees of Fall River Gas or designated agents may,
without additional remuneration, in person or by telephone or telegram, request
the return of proxies. In addition, Fall River Gas has retained Corporate
Investor Communications, Inc. ("CIC") for assistance in the solicitation of
proxies. For its services, CIC will receive a fee estimated at $4,500 plus
reimbursement for reasonable and customary out-of-pocket expenses.

                                   THE MERGER

THIS SECTION OF THE PROXY STATEMENT/PROSPECTUS, AS WELL AS THE NEXT SECTION
ENTITLED "THE MERGER AGREEMENT," DESCRIBES CERTAIN ASPECTS OF THE PROPOSED
MERGER. 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 IS ATTACHED AS APPENDIX A TO THIS PROXY
STATEMENT/PROSPECTUS. WE URGE YOU TO READ THE MERGER AGREEMENT IN ITS ENTIRETY.

FALL RIVER GAS BACKGROUND OF THE MERGER

As part of its long-term planning, Fall River Gas' board has periodically
reviewed and evaluated various strategic options and alternatives available to
maximize the economic return of its stockholders. Fall River Gas' board has
recognized the difficulties Fall River Gas faced in responding to the demands of
a deregulated energy market, in competing with the larger companies being formed
in the consolidation of the energy industry and in continuing to increase
shareholder value. From time to time, Fall River Gas' board has considered
strategic combinations, but found no attractive opportunities to maximize
shareholder value.

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


                                       32
<PAGE>

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 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. At the same time,
Mr. Faxon advised the members of the board of Fall River Gas of the developments
regarding a possible business combination with Southern Union and called a
special meeting of the board of directors. During this time period, Messrs.
Faxon and Thanas fielded informal inquiries from other potential combination
partners, but no offers were received from anyone other than Southern Union.

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. Mr. Faxon
updated the board on his discussions with Southern Union and stated his view
that a strategic merger with a larger company would, among other things: 1)
provide an opportunity for growth; 2) assist Fall River Gas in providing all
energy alternatives to its customers; 3) provide geographical diversity; 4)
permit more aggressive growth; and 5) better enable the company to take
advantage of opportunities in the energy industry.

In addition, Mr. Faxon stated a strategic relationship with Southern Union would
not require Fall River Gas to significantly reduce employees or other assets in
Fall River Gas' service area and should help improve service to its customers.
He noted the changing competitive landscape in the energy industry where
critical mass and complete energy solutions are necessary, the increasing merger
activity and formation of larger companies with which Fall River Gas would be
required to compete, and the limitations of Fall River Gas in terms of potential
sales growth in its existing service territory and access to capital. Fall River
Gas' outside counsel, Rich, May, Bilodeau & Flaherty, P.C., reviewed the board's
fiduciary duties and the standards of conduct to be followed in considering a
merger proposal. Rich, May, Bilodeau & Flaherty, P.C. also discussed key legal
aspects of the proposed merger agreement and the negotiation process with
members of Fall River Gas' board.

Legg Mason, Fall River Gas' financial advisors, discussed the proposed financial
terms of the transaction between Southern Union and Fall River Gas with the
board and rendered its written opinion that, as of the date of the meeting and
based upon and subject to certain matters stated in its opinion, the
consideration to be received by the stockholders of Fall River Gas in the
proposed merger was fair to the stockholders from a financial point of view.

Mr. Kelley, Ronald J. Endres, Southern Union's Executive Vice President and
Chief Financial Officer, and Mr. Karam, made a presentation to the Fall River
Gas board of directors describing Southern Union, its


                                       33
<PAGE>

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 the Southern Union presentation, the Fall River Gas board discussed the
terms of the proposed merger agreement, including the stock-for-stock
consideration, valued at $23.50 per share of Fall River Gas common stock. The
sense of the meeting was that the price was fair, but more information should be
gathered regarding Southern Union. Mr. Faxon suggested and the board voted to
and established a special committee of the board for the sole purpose of
gathering additional information regarding Southern Union. The committee members
were Cindy L.J. Audette, Thomas H. Bilodeau and Ronald J. Ferris. Fall River Gas
management then issued a press release stating that Fall River Gas 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. During this
period, the Fall River Gas board members also engaged in discussions with one
another concerning the possible merger.

On the morning of September 17, 1999, the Fall River Gas board again met to
consider the proposed merger. Again, Mr. Faxon stated his support for the
transaction, noting: 1) that the price offered was favorable relative to other
recent comparable transactions; 2) that Fall River Gas' growth prospects in
terms of business and earnings were limited; and 3) that the proposed merger
would not require a significant reduction in employees or assets in Fall River
Gas' service area. He further noted that although there had been inquiries from
third parties, no other offers by other potential merger partners had been
received. Fall River Gas' counsel again reviewed the board's responsibilities
and key aspects of the merger agreement and the special committee presented its
findings. 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.

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 proposed merger agreement, conditions
to closing, as well as a likely time schedule. Legg Mason, by conference
telephone, noted that it considered the change from an all-stock transaction to
a cash-and-stock transaction to be favorable to the stockholders and confirmed
its view that the consideration to be received by the stockholders of Fall River
Gas in the proposed merger was fair to the stockholders from a financial point
of view. Legg Mason orally advised that it would change its written opinion
delivered to the Fall River Gas


                                       34
<PAGE>

board of directors on September 7, 1999 to reflect this change in the merger
consideration. Legg Mason delivered their revised written opinion on October 4,
1999.

The Fall River Gas board, after further discussion and for the reasons listed
under "-Fall River Gas Reasons for the Merger; Recommendation of Fall River Gas'
Board of Directors," unanimously approved the merger agreement. Following the
meeting, Messrs. Faxon and Thanas called representatives of Southern Union to
communicate the board's approval. After the close of business October 4, 1999,
the merger agreement was executed and the merger was publicly announced.

FALL RIVER GAS REASONS FOR THE MERGER; RECOMMENDATION OF FALL RIVER GAS' BOARD
OF DIRECTORS

Recognizing the need for Fall River Gas to be larger in order to respond to the
demands of a deregulated energy market and to compete with the larger companies
being formed in the consolidation of the energy industry, the Fall River Gas
board authorized the exploration of a strategic stock-for-stock merger. The Fall
River Gas board believes that the merger with Southern Union, among other
things, should help Fall River Gas: 1) to provide all energy alternatives to the
consumer; 2) to diversify geographically; 3) to grow aggressively where
advisable; and 4) to be better able to take advantage of opportunities in the
energy industry. In addition, this strategic relationship should not require
Fall River Gas to significantly reduce employees or other assets in
Massachusetts and should help improve service to its customers.

In reaching its decision to approve the merger and the merger agreement and to
recommend that Fall River Gas stockholders adopt the merger agreement, the Fall
River Gas board consulted with its management, financial and legal advisors and
considered a number of factors, including, among others, the following material
factors:

-    the belief that the merger with Southern Union will result in a combined
     entity with sufficient size and scope to compete effectively in the
     deregulated energy market;

-    the merger consideration negotiated with Southern Union, including the
     collar provision designed to protect Fall River Gas stockholders with
     respect to the value of the stock consideration to be received by them in
     the merger, and the implied premium that the merger consideration
     represented over then recent market prices of Fall River Gas common stock;

-    the written opinion of Legg Mason, a copy of which is attached as Appendix
     B to this proxy statement/prospectus, that subject to the assumptions and
     limitations contained in that opinion, the consideration to be received in
     the merger by the stockholders of Fall River Gas is fair, from a financial
     point of view, to the stockholders;

-    the financial presentation made by Legg Mason to the Fall River Gas board
     in connection with delivering its written opinion;

-    the benefits to Fall River Gas' employees and the communities served by
     Fall River Gas, including the retention of local operations and provisions
     of Southern Union's benefit plans;

-    the terms and conditions of the merger agreement, including:


                                       35
<PAGE>

     -   the representations and warranties Fall River Gas has made to Southern
         Union;

     -   the representations and warranties Southern Union has made to Fall
         River Gas;

     -   the closing conditions;

     -   the ability of Fall River Gas, under certain circumstances, to provide
         information to, and enter into negotiations with, third parties with
         respect to certain unsolicited offers to acquire Fall River Gas;

     -   the ability to terminate the merger agreement in order to enter into
         an agreement with a person making an unsolicited offer, which is more
         favorable to Fall River Gas stockholders from a financial point of
         view than the merger after paying a termination fee to Southern Union
         and giving Southern Union the opportunity to match any offer made by
         such a third party; and

     -   the ability of Fall River Gas to terminate the merger agreement if the
         average trading price of Southern Union common stock for the valuation
         period ending shortly before the closing falls below $15.00 (see "The
         Merger Agreement -- Merger Consideration");

-   the structure of the transaction, which is intended to qualify as a
    "reorganization" for United States federal income tax purposes, so that the
    stockholders of Fall River Gas, as such, will recognize gain only to the
    extent they receive cash in exchange for their shares of Fall River Gas
    common stock;

-   information concerning the business, financial condition, results of
    operations and prospects, including, but not limited to, the potential for
    growth, development and profitability of Southern Union;

-   the projected pro forma ownership of Southern Union by the stockholders of
    Fall River Gas implied by the exchange ratio;

-   the historical market prices and trading information with respect to Fall
    River Gas common stock and Southern Union common stock; and

-   the likelihood that the merger would be consummated.

During its deliberations regarding the proposed merger and merger agreement,
the Fall River Gas board also analyzed certain risks associated with the
merger, including the integration of the two companies and the risk of
obtaining the necessary regulatory approvals for the merger in acceptable
form. After reviewing these matters, the Fall River Gas board determined that
the benefits of the merger outweighed any risks entailed in these matters.

At its meeting on September 30, 1999, the Fall River Gas board unanimously
approved the terms of the merger agreement and the related transactions,
determined that the terms of the merger are in the best interests of Fall
River Gas and Fall River Gas' stockholders, and recommended approval and
adoption of the merger agreement by Fall River Gas' stockholders.


                                      36

<PAGE>

This discussion of the information and factors considered by the Fall River
Gas board in making their decision is not intended to be exhaustive but is
believed to include all material factors considered in connection with the
Fall River Gas board's evaluation of the merger. The Fall River Gas board did
not find it practicable to, and did not, quantify or otherwise assign relative
weights to, the specific factors considered in reaching its determination. In
addition, individual members of the Fall River Gas board may have given
different weight to different factors. Based on the total mix of information
available to them, all of the directors decided to approve and recommend the
merger to Fall River Gas stockholders.

In considering the recommendation of the Fall River Gas board with respect to
the merger agreement, Fall River Gas stockholders should be aware that certain
members of the Fall River Gas board and Fall River Gas employees have
interests in the merger that are different from, or in addition to, the
interests of stockholders of Fall River Gas generally. The Fall River Gas
board was aware of these interests and considered them, among other matters,
in approving the merger agreement. See "The Merger - Potential Conflicts and
Interests of Certain Persons in the Merger."

OPINION OF FALL RIVER GAS' FINANCIAL ADVISOR

Legg Mason rendered its oral and written opinion to the Fall River Gas board
at their meeting on September 30, 1999, that, as of that date, and subject to
certain assumptions, factors and limitations set forth in such opinion as
described below, the merger consideration to be received by Fall River Gas
stockholders pursuant to the merger agreement was fair to stockholders from a
financial point of view.

The full text of the written opinion of Legg Mason dated October 4, 1999,
which sets forth the assumptions made, matters considered, scope and
limitations on the review undertaken, and procedures followed by Legg Mason in
connection with the opinion, is attached as Appendix B to this proxy
statement/prospectus. Stockholders are urged to read this opinion in its
entirety. Legg Mason's opinion is directed only to the consideration to be
received by stockholders pursuant to the merger agreement and does not
constitute a recommendation to any stockholder as to how such stockholder
should vote at the special meeting. Legg Mason's opinion will not be updated
prior to or at the closing of the merger. The summary of the opinion of Legg
Mason set forth in this proxy statement/prospectus is qualified in its
entirety by reference to the full text of such opinion. In connection with
this engagement, Fall River Gas did not request Legg Mason, and Legg Mason did
not assist Fall River Gas, to determine the exchange ratio provided for in the
merger agreement. The exchange ratio was determined through arm's-length
negotiations between Fall River Gas and Southern Union.

In connection with its opinion, Legg Mason reviewed, among other things, (a)
the merger agreement and certain related documents, (b) the audited
consolidated financial statements of Fall River Gas as of and for the years
ended September 30, 1998, 1997, 1996 and 1995, (c) the unaudited financial
statements of Fall River Gas as of and for the nine-month period ended June
30, 1999, (d) the audited consolidated financial statements of Southern Union
as of and for the years ended June 30, 1999, 1998, 1997, 1996 and 1995. Legg
Mason also had discussions with members of the senior management of Fall River
Gas and Southern Union regarding the past and current business operations,
financial condition and future prospects of their respective companies. In
addition, Legg Mason reviewed the reported price and trading activity for the
shares of Fall River Gas common stock and the shares of Southern Union common
stock, compared certain financial and stock market data for Fall River Gas and
Southern Union with similar information for certain


                                      37

<PAGE>

other publicly-traded companies, analyzed publicly available information
concerning the terms of certain selected business combinations in the gas
distribution utility industry, and performed such other studies and analyses
as Legg Mason considered necessary or appropriate.

Legg Mason relied without independent verification upon the accuracy and
completeness of all of the financial and other information reviewed by them
for purposes of their opinion. Legg Mason did not make an independent
evaluation or appraisal of the assets and liabilities of Fall River Gas or
Southern Union or any of their subsidiaries and they were not furnished with
any such evaluation or appraisal.

The following is a summary of the financial analyses Legg Mason utilized in
connection with providing its written opinion to the Fall River Gas board.

STOCK TRADING HISTORY. Legg Mason examined the history of the trading price
and volume for the shares of Fall River Gas common stock. This examination
showed that during the period from October 2, 1998 to October 1, 1999, the
trading price of Fall River Gas common stock ranged from $15 3/8 per share to
$21 7/8 per share. This examination also showed that over the period from
October 4, 1994 to October 1, 1999, the trading price of Fall River Gas common
stock ranged from $12.75 per share to $27.00 per share. This range may be
compared to the merger consideration. Legg Mason also examined the history of
the trading price and volume for the shares of Southern Union common stock
(not adjusted for the 5% Southern Union stock dividends distributed on June
30, 2000 and August 6, 1999). This examination showed that during the
four-month period from June 1, 1999 to October 1, 1999, the trading price of
Southern Union common stock ranged from $18.00 per share to $21 23/32 per
share. The closing price of Southern Union common stock on October 1, 1999 was
$18.75 per share, which was used as the basis for the exchange rate in the
merger agreement. In addition, this examination showed that over the period
from October 3, 1997 to October 1, 1999, the trading price of Southern Union
common stock ranged from $13.25 per share to $23 7/32 per share.

COMPARISON OF SELECTED PEER COMPANIES. Legg Mason compared selected historical
stock market and balance sheet data and financial ratios for Fall River Gas to
the corresponding data and ratios of the following companies: Berkshire Energy
Resources, Cascade Natural Gas Corporation, Delta Natural Gas Company, Inc.,
Energy North, Inc., Energy South, Inc., Energy West Incorporated, ProvEnergy,
RGC Resources, Inc. and Valley Resources. The multiples of Fall River Gas were
calculated using a price of $20.75 per share for Fall River Gas common stock,
the closing price as of October 1, 1999. Such data and ratios included, among
other things, equity value as a multiple of latest twelve months ("LTM")
earnings per share ("EPS"), projected 1999 earnings per share, projected 2000
earnings per share and stockholders' equity; total market capitalization as a
multiple of LTM revenues, of LTM earnings before interest, taxes, depreciation
and amortization ("EBITDA") and of LTM earnings before interest and taxes
("EBIT"). Projected earnings per share data was provided by First Call
Analysts' Research and FactSet Data Systems. EBITDA (which is not a measure of
financial performance under generally accepted accounting principles) is used
by investment banking firms as one measure of a company's financial
performance. EBITDA should not be construed as an alternative to operating
income (as determined in accordance with generally accepted accounting
principles), as an indicator of a company's performance or cash flows from
operating activities (as determined in accordance with generally accepted
accounting principles) or as a measure of liquidity.

An analysis of equity value as a multiple of LTM earnings per share for the
selected peer companies yielded a range of 10.2x to 24.1x with a median of
15.5x as compared to 22.4x for Fall River Gas. An analysis of


                                      38

equity value as a multiple of projected 1999 EPS yielded a range of 13.4x to
23.6x with a median of 15.9x as compared to 21.2x for Fall River Gas. An
analysis of equity value as a multiple of projected 2000 EPS yielded a range
of 11.8x to 20.3x with a median of 14.5x as compared with 16.2x for Fall River
Gas. An analysis of total market capitalization as a multiple of LTM EBITDA
yielded a range of 6.3x to 9.7x with a median of 7.4x as compared to 11.9x for
Fall River Gas. An analysis of total market capitalization as a multiple of
LTM EBIT yielded a range of 9.1x to 15.9x with a median of 10.9x as compared
to 19.3x for Fall River Gas.

SELECTED TRANSACTIONS ANALYSIS. Using publicly available information, Legg
Mason analyzed the purchase price and implied transaction value multiples paid
or announced to be paid in the following selected merger and acquisition
transactions in the gas distribution utility industry: Northeast
Utilities/Yankee Energy; Eastern/Colonial Gas; Carolina Power/North Carolina
Natural Gas; EnergyEast/Connecticut Energy; Southern Union/PEI; SCANA
Corp./Public Service Co. of North Carolina; Eastern Enterprises/Colonial Gas
Co.; Energy East Corp./Connecticut Energy Corp.; Carolina Power and
Light/North Carolina Natural Gas; Dominion Resources, Inc./Consolidated
Natural Gas; NiSource Inc./Bay State Gas; Eastern Enterprises/Essex County Gas
Co.; and Atmos Energy Corp./United Cities Gas Co. (the "Selected
Transactions"). Such analysis indicated that for the Selected Transactions,
(i) total transaction value as a multiple of LTM revenue ranged from 1.6x to
3.2x with a mean of 2.3x compared to 1.7x for the contemplated transaction,
(ii) total transaction value as a multiple of LTM EBITDA ranged from 7.5x to
13.9x with a mean of 10.6x, as compared to 13.1x for the contemplated
transaction, (iii) equity value as a multiple of LTM net income ranged from
20.0x to 31.8x (exclusive of a transaction at 83.3x and 47.4 which was not
included in the mean) with a mean of 24.3x, as compared to 25.6x for the
contemplated transaction, and (iv) equity value as a multiple of stockholders'
equity ranged from 1.9x to 3.0x with a median of 2.5x as compared to 2.9x for
the contemplated transaction.

No company, transaction, or business used in the comparison with comparable
companies or selected transactions analysis as a comparison is identical to
Fall River Gas or the merger. Accordingly, an analysis of the results of the
foregoing is not entirely mathematical. Instead, it involves complex
considerations and judgments concerning differences in financial and operating
characteristics and other factors that could affect the acquisition, public
trading or other values of the comparable companies, selected transactions or
the company or transaction to which they are being compared.

DISCOUNTED CASH FLOW ANALYSIS. Legg Mason performed a discounted cash flow
analysis of Fall River Gas. Legg Mason calculated a net present value of
estimated free cash flows for the years 1999 through 2003 using discount rates
ranging from 5.9% to 7.5%. Legg Mason calculated Fall River Gas' terminal
values in the year 2003 based on multiples ranging from 10.4x EBIT to 12.8x
EBIT. These terminal values were then discounted to present value using
discount rates from 7.2% to 9.2%. Using the foregoing terminal values and
discounted cash flows for Fall River Gas, the equity value ranged from $7.30
to $14.90, as compared to the equity value implied by the exchange ratio of
$23.50 per share.

The preparation of a fairness opinion is a complex process and is not
necessarily susceptible to practical analysis or summary description.
Selecting portions of the analyses or of the summary set forth above, without
considering the analyses as a whole, could create an incomplete view of the
processes underlying Legg Mason's opinion. In arriving at its fairness
determination, Legg Mason considered the results of all such analyses. The
analyses were prepared solely for purposes of Legg Mason providing its opinion
to the


                                      39

<PAGE>

Fall River Gas board as to the fairness of the merger consideration pursuant
to the merger agreement to the holders of shares of Fall River Gas common
stock and do not purport to be appraisals that necessarily reflect the prices
at which assets, businesses or securities actually may be sold. Analyses based
on forecasts of future results are not necessarily indicative of actual future
results, which may be significantly more or less favorable than suggested by
such analyses. Because such analyses are inherently subject to uncertainty,
being based upon numerous factors or events beyond the control of the parties,
none of Fall River Gas, Southern Union, Legg Mason or any other person assumes
responsibility if future results are materially different from those forecast.

As described above, Legg Mason's opinion to the Fall River Gas board was one
of the many factors taken into consideration by the Fall River Gas board in
making its determination to approve the merger agreement. The foregoing
summary does not purport to be a complete description of the analyses
performed by Legg Mason and is qualified by reference to the written opinion
of Legg Mason set forth in Appendix B hereto.

Legg Mason, as part of its investment banking business, is continually engaged
in the valuation of businesses and their securities in connection with mergers
and acquisitions, negotiated underwritings, competitive biddings, secondary
distributions of listed and unlisted securities, private placements and
valuations for estate, corporate and other purposes. Fall River Gas selected
Legg Mason as its financial adviser because Legg Mason is a nationally
recognized investment banking firm that has substantial experience in
transactions similar to the merger.

Legg Mason provides a full range of financial, advisory and brokerage services
and in the course of its normal trading activities may from time to time
effect transactions and hold positions in the securities or options on
securities of Fall River Gas and/or Southern Union for its own account and for
the accounts of customers.

Pursuant to an engagement letter dated August 24, 1999, Fall River Gas engaged
Legg Mason to act as its financial advisor in connection with the possible
merger of Fall River Gas and Southern Union. Pursuant to the terms of the
engagement letter, Fall River Gas agreed to pay Legg Mason $100,000 upon
delivery of a written fairness opinion to the board. Fall River Gas has agreed
to reimburse Legg Mason for its reasonable out-of-pocket expenses, including
attorney's fees, and to indemnify Legg Mason against certain liabilities,
including certain liabilities under federal securities laws.

SOUTHERN UNION BACKGROUND OF THE MERGER; REASONS FOR APPROVAL BY THE SOUTHERN
UNION BOARD OF DIRECTORS

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.

On August 24, 1999, the Southern Union board unanimously approved an all stock
merger agreement with Fall River Gas. In reaching its determination that a
merger with Fall River Gas is in the best interest of Southern Union and its
stockholders, the Southern Union board 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


                                      40

<PAGE>

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 merger agreement consistent with those terms
    described under "The Merger Agreement" except that the consideration was
    all stock;

-   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 potential mergers, including to
    integrate the operations of those companies, and the risks inherent in such
    integration;

-   other matters described under "Risk Factors and Other Considerations" and
    "Forward-Looking Statements May Prove Inaccurate"; and

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

On September 27, 1999, the Executive Committee of Southern Union's board
approved a revised offer in order to permit the substitution of cash for some
portion of the consideration Fall River Gas stockholders would receive in
connection with the merger.

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 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 the transaction. 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 intended to seek such stockholder approval. 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 merger at a special
meeting of stockholders, due to the merger being in the best interests of
Southern Union, its stockholders, employees and customers.

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.

POTENTIAL CONFLICTS AND INTERESTS OF CERTAIN PERSONS IN THE MERGER

In considering the recommendation of the Fall River Gas board with respect to
approving the merger, Fall River Gas stockholders 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. The Fall River Gas board was aware of these interests and considered
them in approving the merger agreement.

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 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 Messrs. Faxon, Thanas and Fanning
continue 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 in certain
circumstances.

DEFENSE, INDEMNIFICATION AND INSURANCE FOR FALL RIVER GAS OFFICERS AND
DIRECTORS. For a period of six years after the completion of the 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


                                      42

<PAGE>

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

SIGNIFICANT U.S. FEDERAL INCOME TAX CONSEQUENCES OF THE MERGER

The following discussion is intended only as a summary of the material U.S.
federal income tax consequences of the merger to Southern Union, Fall River
Gas and Fall River Gas stockholders and does not purport to be a complete
analysis or description of all potential tax effects of the merger. The
discussion assumes that holders of Fall River Gas common stock hold such stock
as "capital assets" within the meaning of Section 1221 of the Internal Revenue
Code. 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 of the date of this proxy statement/prospectus.
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/prospectus. Any such change could
apply retroactively and could affect the accuracy of such discussion.

Each stockholder of Fall River Gas is urged to consult such stockholder's own
tax advisor as to the specific tax consequences to such stockholder of the
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
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 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 merger. Each of the Southern Union Tax Opinion and the Fall River Gas
Tax Opinion will be based on certain assumptions, including that the merger
will be consummated exactly as described in this proxy statement/prospectus
and in the 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


                                       44

<PAGE>

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 merger.

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

CONSEQUENCES TO FALL RIVER GAS STOCKHOLDERS RECEIVING SOLELY SOUTHERN UNION
COMMON STOCK. A Fall River Gas stockholder will generally recognize neither
gain nor loss for U.S. federal income tax purposes with respect to the receipt
solely of Southern Union common stock in exchange for Fall River Gas common
stock pursuant to the merger. The aggregate tax basis of the Southern Union
common stock received by a Fall River Gas stockholder will be the same as the
aggregate tax basis of the Fall River Gas common stock surrendered in exchange
therefor pursuant to the merger. The holding period of the Southern Union
common stock will include the holding period of the Fall River Gas common
stock surrendered in exchange therefor.

CONSEQUENCES TO FALL RIVER GAS STOCKHOLDERS RECEIVING SOLELY CASH. A Fall
River Gas stockholder will generally recognize gain or loss for U.S. federal
income tax purposes with respect to the receipt solely of cash in exchange for
Fall River Gas common stock pursuant to the merger. Any gain or loss
recognized by a Fall River Gas stockholder will be capital gain or loss, and
will be long-term capital gain or loss if the holding period for the Fall
River Gas common stock surrendered is more than one year. The amount of gain
or loss will be equal to the difference between the amount of cash received
and the tax basis of the Fall River Gas common stock surrendered.

CONSEQUENCES TO FALL RIVER GAS STOCKHOLDERS RECEIVING CASH AND SOUTHERN UNION
COMMON STOCK. A Fall River Gas stockholder will generally recognize gain, but
not loss, for U.S. federal income tax purposes with respect to the receipt of
Southern Union common stock and cash in exchange for Fall River Gas common
stock pursuant to the merger. The amount of gain, if any, recognized by a Fall
River Gas stockholder will be equal to the lesser of (i) the amount of gain
realized (i.e., the excess of the amount of cash, including cash received in
lieu of fractional shares, and the fair market value of Southern Union common
stock received in the merger over the tax basis of the Fall River Gas common
stock surrendered) or (ii) the amount of cash, including cash received in lieu
of fractional shares, received in the merger. In the case of a Fall River Gas
stockholder that owns more than one "block" of Fall River Gas common stock,
the amount of gain recognized should be calculated separately with respect to
each "block" surrendered in the merger. For purposes of such calculation, the
aggregate amount of cash and Southern Union common stock received by the Fall
River Gas stockholder will be allocated proportionally among the "blocks" of
Fall River Gas common stock surrendered in exchange therefor pursuant to the
merger. The aggregate tax basis of the Southern Union common stock received by
a Fall River Gas stockholder will be the same as the aggregate tax basis of
the Fall River Gas common stock surrendered in exchange therefor pursuant to
the merger, decreased by the total amount of cash received and increased by
the amount of gain recognized. The holding period of the Southern Union common
stock will include the holding period of the Fall River Gas common stock
surrendered in exchange therefor.

Any gain recognized by a Fall River Gas stockholder receiving both Southern
Union common stock and cash will be capital gain, and will be long-term
capital gain if the holding period for the Fall River Gas


                                      45

<PAGE>

common stock surrendered is more than one year, unless the receipt of cash has
"the effect of the distribution of a dividend" within the meaning of Section
356 of the Internal Revenue Code. If the receipt of cash has such an effect,
the recognized gain will be taxed as ordinary income to the extent of the Fall
River Gas stockholder's ratable share of Fall River Gas', and arguably
Southern Union's, undistributed earnings and profits, and any remaining gain
will be taxed as capital gain.

In determining whether cash received by a stockholder who also receives stock
in a reorganization has the effect of a dividend distribution, principles
similar to those governing redemptions under Section 302 of the Internal
Revenue Code apply. In applying those principles, Fall River Gas stockholders
will be treated as if they had received solely Southern Union common stock in
the merger (instead of the combination of shares of Southern Union common
stock and cash actually received) and Southern Union had then redeemed for
cash a portion of the Southern Union common stock the Fall River Gas
stockholders would be treated as having received. Generally, under Section 302
of the Internal Revenue Code, amounts distributed in redemption of a
stockholder's stock will not be taxed as a dividend if (a) the distribution is
"substantially disproportionate" with respect to the stockholder, or (b) the
distribution is "not essentially equivalent to a dividend" with respect to the
stockholder. A distribution in redemption is "substantially disproportionate"
with respect to a stockholder if the percentage of outstanding voting shares
of the issuing corporation owned by such stockholder immediately after the
redemption is less than 50% of the total outstanding and less than 80% of the
percentage of voting shares owned by such stockholder immediately prior to the
redemption. Whether a distribution in redemption is "not essentially
equivalent to a dividend" depends on whether, under the particular
stockholder's facts and circumstances, the redemption results in a "meaningful
reduction" of the stockholder's proportionate interest in the issuer. The IRS
has indicated in published rulings that even a small reduction in the
proportionate interest of a stockholder in a publicly held corporation whose
relative stock interest is minimal and who exercises no control or management
power over the affairs of the corporation may constitute such a "meaningful
reduction." In applying these tests, a stockholder is treated as owning shares
owned by certain related persons, and sales or acquisitions of Fall River Gas
common stock or Southern Union common stock which occur contemporaneously with
the merger may be taken into account. Because of the complexity of the tests
under Section 302 of the Internal Revenue Code, Fall River Gas stockholders
are urged to consult their own tax advisors regarding the proper treatment of
the gain recognized by such stockholder in the merger.

BACKUP WITHHOLDING TAX. Unless an exemption applies, the paying agent will be
required to withhold 31% of any cash payments to which a Fall River Gas
stockholder or other payee is entitled pursuant to the merger, unless the
stockholder or other payee provides his or her tax identification number
(social security number or employer identification number) and certifies that
such number is correct. Each Fall River Gas stockholder and, if applicable,
each other payee is required to complete and sign the Form W-9 that will be
included as part of the transmittal letter sent to Fall River Gas stockholders
by Southern Union to avoid backup withholding, unless an applicable exemption
exists and is proved in a manner satisfactory to Southern Union and the paying
agent.

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 merger.

REGULATORY MATTERS


                                      46

<PAGE>

The following is a summary of the material regulatory requirements affecting
the 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 managements of
Southern Union and Fall River Gas believe that the necessary approvals can be
obtained in 2000, and presently expect that they all will be received by
September, 2000. See "Risk Factors and Other Considerations - Approvals May
Not Be Obtained or May Contain Unacceptable Restrictions."

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 the Fall River Gas merger on June 28, 2000. The approvals of the
PPUC and the FPSC for the securities issuance and debt assumption in
connection with the merger are still 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 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 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
has advised Fall River Gas and the MDTE that it intends to seek, and through
its proxy statement, is seeking such stockholder approval at the Southern
Union special meeting.

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 mergers, and
notwithstanding that the


                                      47

<PAGE>

waiting period has terminated or the mergers may have been consummated, the
Federal Trade Commission, 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 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.

GENERAL. Fall River Gas possesses rights and franchises, and environmental
permits and licenses. Some of these may need to be transferred, renewed or
replaced as a result of the merger. The companies do not anticipate any
difficulties at the present time in making or obtaining such transfers,
renewals or replacements.

Under the merger agreement, Southern Union and Fall River Gas have agreed to
use their reasonable best efforts to obtain all necessary material permits,
licenses, franchises and other governmental authorizations needed to
consummate or effect the transactions contemplated by the merger agreement.
Various parties may seek intervention in the proceedings associated with the
regulatory approval process in an attempt to oppose the merger or to have
conditions imposed upon the receipt of the necessary approvals. Although
Southern Union and Fall River Gas believe that they will receive the requisite
regulatory approvals for the merger, the timing of their receipt cannot be
determined. It is a condition to the consummation of the merger (subject to
waiver by Southern Union and Fall River Gas) that final non-appealable orders
approving the merger be obtained from the various federal and state
commissions described above. See "The Merger Agreement - Conditions to the
Completion of the Merger."

ACCOUNTING TREATMENT

The Unaudited Pro Forma Combined Condensed Financial Statements appearing
elsewhere in this proxy statement/prospectus are based upon certain
assumptions, as described in the pro forma combined condensed financial
statements, and are included for informational purposes only. The merger will
be accounted for under 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 merger
will remain unchanged. On the closing date, the combined 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."

NO APPRAISAL RIGHTS

Under Massachusetts law, stockholders of Fall River Gas who object to approval
of the merger agreement are not entitled to demand separate payment or an
appraisal of their shares in connection with the merger.

LISTING OF SOUTHERN UNION COMMON STOCK


                                      48

<PAGE>

It is a condition to the completion of the 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
Merger Agreement - Conditions to the Completion of the 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
merger in violation of the Securities Act or the rules and regulations adopted
by the SEC thereunder. See "The 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 Merger Agreement - Conditions to the Completion of the Merger
- Additional Closing Conditions for Southern Union's Benefit."

This proxy statement/prospectus does not cover resales of Southern Union
common stock received by any person who may be deemed to be an affiliate of
Fall River Gas.

                            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 under the merger agreement, 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. See "The Merger Agreement - Merger Consideration."
Southern Union's management currently anticipates that substantially all of
these costs will be financed through external sources. The financings may
include the refinancing by Southern Union of some or all of the approximately
$19.5 million of outstanding debt of Fall River Gas in connection with or soon
after the consummation of the merger. Southern Union anticipates soliciting
consents from the holders of Fall River Gas' mortgage bonds 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


                                      49

<PAGE>

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 mergers and acquisitions that Southern Union has agreed to consummate but
not completed. See "Risk Factors and Other Considerations The Terms of
Merger-Related Financings May Adversely Affect the Combined Company." 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.

                              THE MERGER AGREEMENT

This section is a summary of the material terms of the 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 merger agreement. You should refer to the full text of the
merger agreement for details of the merger and the terms and conditions of the
merger agreement.

STRUCTURE OF THE MERGER

Under the 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 certificate of incorporation
and bylaws will remain in effect after the merger, and Southern Union's
management and Board of Directors will remain the same as a result of the
merger, except as specifically discussed in this proxy statement/prospectus.
See "Comparison of Fall River Gas and Southern Union Stockholder Rights."

As a result of the 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, 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


                                      50

<PAGE>

General Corporation Law ("DGCL"). The merger will become effective upon filing
of these documents. This moment is referred to as the "effective time."

MERGER CONSIDERATION

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

Each share of your Fall River Gas common stock that you elect 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 your Fall River Gas common stock that you elect 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, except as described below. Southern Union will not issue any
fractional shares of its common stock in connection with the merger. Instead,
you will be given cash for any fractional shares of Southern Union common
stock you would otherwise receive.

You will be entitled to receive Southern Union common stock in the merger if:

-   you elect to receive Southern Union common stock;

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

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

-   you do not properly complete the form of election provided to you 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 you will receive for
each share of your 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.


                                      51

<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 merger
    agreement. If Fall River Gas does not terminate the merger agreement, you
    will receive 1.39259 shares of Southern Union common stock per share of
    Fall River Gas common stock.

PROCEDURE FOR FILING ELECTIONS AND CONVERTING FALL RIVER GAS COMMON STOCK INTO
MERGER CONSIDERATION

A form of election and complete instructions for properly making an election
to receive either cash or Southern Union common stock or a combination of cash
and Southern Union common stock will be delivered under separate cover to
stockholders of record of Fall River Gas (determined as of a record date as
close as practicable to the date of mailing) at least 15 business days prior
to the anticipated closing date of the merger, which is expected to occur in
September 2000.

Fall River Gas stockholders will be entitled to choose one of the following
consideration options, which will be listed on their form of election:

-   to receive cash for each share of Fall River Gas they own;

-   to receive Southern Union common stock for each share of Fall River Gas
    they own;

-   to exchange some of their shares of Fall River Gas for cash and some for
    Southern Union common stock; or

-   to indicate no preference as to type of consideration.

You will be eligible to receive cash only if the paying agent has received a
properly completed form of election at its designated office or offices by
4:00 p.m., Eastern Time, on the third business day prior to the closing date
of the merger. You will be eligible to receive as consideration only shares of
Southern Union common stock if:

-   the form of election you submit indicates a preference to receive only
    shares of Southern Union common stock;

-   the form of election you submit indicates no preference as to form of
    consideration; or


                                      52

<PAGE>

-   you fail to submit a properly completed form of election prior to the
    deadline for submitting cash elections.

An election may be revoked only if Southern Union's paying agent receives
written notice of revocation prior to the deadline for submitting cash
elections.

PAYING AGENT; LOST CERTIFICATES

BankBoston, N.A. c/o EquiServe, L.P. will act as paying agent for you in
connection with the merger.

Promptly following the effective time, the exchange agent will mail to you a
letter of transmittal and instructions regarding the surrender of your Fall
River Gas common stock certificates for cancellation. Promptly after receiving
your certificates together with the letter of transmittal, duly executed, the
exchange agent will send you the Southern Union common stock and/or the cash
you will be entitled to receive.

No fractional shares of Southern Union common stock will be issued in the
merger. Instead of fractional shares, you will receive cash in an amount equal
to the value of the fractional shares to which you would otherwise have been
entitled based on the closing price of a share of Southern Union common stock
on the NYSE on the trading day immediately prior to the closing date.

If the merger consideration is to be paid to a person other than the person in
whose name the surrendered certificate is registered, the surrendered
certificate must be properly endorsed and the person requesting payment must
have paid any transfer and other taxes required in connection with payment of
the merger consideration to a person other than the registered holder of the
surrendered certificate or must establish to the satisfaction of Southern
Union that taxes do not apply.

If your certificates have been lost, stolen or destroyed, you must provide the
exchange agent with an affidavit to that effect. In addition, you will be
required to give the paying agent a bond in an amount as it may ordinarily
require and you must indemnify Southern Union against any claim that may be
made against Southern Union with respect to the certificate claimed to have
been lost, stolen or destroyed.

Southern Union will not be liable to you for merger consideration delivered to
a public official pursuant to applicable law. Seven years after the effective
time, any portion of the merger consideration that remains unclaimed by Fall
River Gas' stockholders will, to the extent permitted by applicable law,
become the property of Southern Union.

YOU SHOULD NOT SEND IN YOUR STOCK CERTIFICATES UNTIL YOU RECEIVE A TRANSMITTAL
LETTER.

FALL RIVER GAS INDENTURE

Fall River Gas will use its reasonable best efforts to obtain, prior to the
effective time of the merger, consents from all holders of First Mortgage
Bonds outstanding under the Indenture of First Mortgage, dated as of December
1, 1952, between Fall River Gas and State Street Bank and Trust Company (the
"Fall River Gas Indenture"), to amendments to the Fall River Gas Indenture
requested by Southern Union pursuant to


                                      53

FALL RIVER GAS SPECIAL MEETING; SOLICITATION OF PROXIES. Fall River Gas has
agreed:

-   to use its reasonable best efforts to solicit from its stockholders proxies
    in favor of the merger;

-   to take all steps necessary to duly call, give notice of, convene and hold
    a meeting of its stockholders for the purpose of securing the approval and
    adoption of the merger agreement and the consummation of transactions
    related to the merger agreement by its stockholders;

-   to distribute proxy statements to its stockholders in accordance with
    applicable federal and state law and its organizational documents; and

-   to recommend to its stockholders the approval of the merger agreement,
    subject to the fiduciary duties of its board of directors.

FALL RIVER GAS VOTING AGREEMENT. In connection with the merger, Barbara N.
Jarabek, as trustee of 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 entered into a voting agreement with
Southern Union. According to the terms of the voting agreement, these
stockholders agreed: 1) to vote or cause to be voted their shares of Fall
River Gas common stock in favor of the merger and the adoption and approval of
the merger agreement, and 2) to grant Southern Union an irrevocable proxy to
vote their shares of Fall River Gas common stock for the approval and adoption
by the Fall River Gas stockholders of the merger agreement and the performance
of transactions related to the merger. As of the special meeting record date,
the number of shares beneficially owned by the Fall River Gas stockholders who
entered the voting agreement and granted this irrevocable proxy represent
approximately 25.6% of the outstanding shares of Fall River Gas common stock
entitled to vote on the approval and adoption of the merger agreement and
performance of transactions related to the merger agreement.

Of the 572,510 shares of Fall River Gas common stock represented by the
stockholders who are parties to the voting agreement, as of May 31, 2000,
276,800 shares were beneficially owned by executive officers and directors of
Fall River Gas. The voting agreement is attached as Appendix C to this proxy
statement/prospectus.

EMPLOYEES; BENEFITS. For employees (excluding unionized employees) of Fall
River Gas and its subsidiary, Southern Union has agreed:

    with benefits no less favorable in the aggregate than the benefits provided
    under Fall River Gas' benefit plans during the 12 months immediately
    following the closing date;

-   to recognize, for purposes of eligibility, vesting and benefit accrual
    under all benefit plans provided to such employees after the closing date,
    the tenure of employment, as recognized by Fall River Gas or of its
    subsidiary as of the closing date;


                                      57

    must be taken by the end of the calendar year of the closing date, except
    where Fall River Gas or Southern Union requests that an employee forgo his
    or her vacation for business-related reasons; and

-   to recognize, for purposes of awarding vacation time at the beginning of
    each calendar year following the closing date, the tenure of employment, as
    recognized by Fall River Gas or of its subsidiary as of the closing date.

Southern Union has also agreed to assume, at the effective time, all
collective bargaining agreements covering employees of Fall River Gas and its
subsidiary, and to discharge when due any and all liabilities of Fall River
Gas and its subsidiary under the collective bargaining agreements relating to
periods after the effective time.

other agreements relating to: filings with the SEC; access to offices,
properties, financial statements and other records; use of reasonable efforts
to obtain all necessary consents; approvals and waivers from governmental
bodies and other third parties; and further assurances.

    accounting methods, principles or practices except as required by law,
    rule, regulation or generally accepted accounting principles;

    of Rule 145 under the Securities Act and to use its reasonable efforts to
    provide to Southern Union letters from such persons to the effect that they
    will not dispose of their shares of Southern Union common stock received in
    the merger except in accordance with the applicable provisions of Rule 145
    or in a transaction exempt from registration under the Securities Act
    ("Rule 145 Letters");


                                      58

<PAGE>

-   cooperate and cause its subsidiaries to cooperate with Southern Union's

    instances, negotiate, discuss, approve or recommend any such alternative
    acquisition proposal (see "-No Solicitation by Fall River Gas"); and

-   obtain consents for the merger from all holders of each series of First
    Mortgage Bonds issued and outstanding under the Fall River Gas Indenture.

The merger agreement also contains certain additional covenants of Southern
Union to, except as provided in the merger agreement:

-   use its reasonable best efforts to obtain, prior to the effective date of
    the merger agreement, all necessary state securities laws or "blue sky"
    permits and approvals and pay all related expenses; and

-   cause the shares of Southern Union's common stock required to be reserved
    for issuance in connection with the merger to be listed on the NYSE.

NO SOLICITATION BY FALL RIVER GAS

The 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," which we 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 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;

-   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


                                      59

<PAGE>

    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 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 merger; and

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

The 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


                                      60

<PAGE>

-   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 merger
    agreement or the 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,
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 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. Concurrently with the termination of the merger
agreement in connection with a Business Combination, Fall River Gas must also
pay the required termination fee (see "-Termination of the 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.

obtain a policy with the best coverage available for a cost not exceeding such
amount. See "The Merger - Potential Conflicts and Interests of Certain Persons
in the Merger."

AMENDMENTS

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

-   by Fall River Gas if:

     -   there is a breach of any representation, warranty, covenant or

<PAGE>

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

           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,
including to reflect independent appraisals, which have not been completed.


                                      67

<PAGE>

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 (G) 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:


                                      75

<PAGE>

    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 portion of 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 for Southern Union
    common stock for the ten trading day period ending on 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.

                                  THE COMPANIES

                                 SOUTHERN UNION

GENERAL

Southern Union was incorporated under the laws of the State of Delaware in
1932 and is one of the fifteen largest gas utility companies 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 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 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 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 5,000 customers in central Florida (including the cities of New Smyrna
Beach, 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,
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. Central to all of Southern Union's present businesses
and strategies are the sale and transportation of natural gas and related
energy services.

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 principally consist of: (i) promoting new sales
opportunities and markets for natural gas and propane; (ii) enhancing
financial and operating performance; and (iii) expanding Southern Union
through development of existing utility businesses and selective acquisition
of new utility businesses. Southern Union's management develops and
continually evaluates these strategies

                                      78

<PAGE>

and their implementation by applying their experience and expertise in
analyzing the energy industry, technological advances, market opportunities
and general business trends. Each of these strategies, as implemented
throughout Southern Union's existing businesses, reflects Southern Union's
commitment to its core gas utility business.

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. See "Forward-Looking
Statements May Prove Inaccurate."

ACQUISITIONS

ACQUISITION OF 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 of 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 nonregulated activities, including the construction,
maintenance and rehabilitation of natural gas distribution pipelines.

MERGER WITH PROVENERGY. On November 14, 1999, Southern Union and ProvEnergy
(NYSE: "PVY") entered into a definitive merger agreement. The agreement calls
for ProvEnergy to merge into Southern Union in a transaction valued at
approximately $400 million, including the assumption of debt. ProvEnergy's
utility subsidiaries will also be merged into Southern Union. ProvEnergy
shareholders will receive $42.50 in cash for each of the approximately 6.1
million shares of ProvEnergy common stock outstanding. ProvEnergy,
headquartered in Providence, Rhode Island, is the parent of two natural gas
subsidiaries. Providence Gas, founded in 1847, is Rhode Island's largest gas
distributor and serves approximately 168,000 natural gas customers in
Providence and Newport and 23 other cities and towns in Rhode Island. North
Attleboro Gas serves approximately 6,000 customers in North Attleboro and
Plainville, Massachusetts. ProvEnergy's oil business serves over 14,000
residential and commercial customers. ProvEnergy's utility service territories
encompass approximately 760 square miles with a population of approximately
850,000. Southern Union anticipates completing the ProvEnergy merger in
September 2000 once all remaining conditions are satisfied, including receipt
of all regulatory approvals. On May 22, 2000, the stockholders of ProvEnergy
approved the terms of the ProvEnergy merger.

MERGER WITH VALLEY RESOURCES. 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

                                      79

<PAGE>

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, each of which will also be merged into Southern Union.
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 primarily for residential
use in its service area, 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 an 80% 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 a patent for a natural gas/diesel co-firing system and has a patent
pending for a device to control the flow of fuel on dual-fuel equipment.
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. Valley Resources
shareholders approved the Valley Resources merger at their special meeting on
June 13, 2000.

                                 FALL RIVER GAS

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, Ltd. (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.

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.

                   DESCRIPTION OF SOUTHERN UNION CAPITAL STOCK

GENERAL

Under the provisions of the Delaware General Corporation Law ("DGCL"), a

were issued and outstanding and no shares of Southern Union preferred stock
were issued and outstanding.

SOUTHERN UNION COMMON STOCK

VOTING RIGHTS. Except with respect to the election of directors, the holders
of Southern Union common stock are entitled to one vote for each share held of

and such stockholder may cast all of such votes for a single nominee or
distribute them among the nominees as such stockholder deems appropriate.

dividends as and when declared by the Southern Union board out of funds
legally available therefor, subject to any preferential dividend rights of
outstanding shares of Southern Union preferred stock.

cumulative preferred stock, upon liquidation, dissolution or winding up of
Southern Union, the holders of Southern Union common stock are entitled to
receive ratably the net assets of Southern Union available after the payment
of all debts and other liabilities.

NO OTHER RIGHTS. Holders of Southern Union common stock have no preemptive,
subscription, redemption or conversion rights.

EFFECT OF THE MERGER. Upon completion of the merger, Fall River Gas'
stockholders will receive shares of Southern Union common stock. Accordingly,
the total number of outstanding shares of Southern Union common stock will
change.

SOUTHERN UNION PREFERRED STOCK

GENERAL. Southern Union, by resolution of the Southern Union board and without
any further vote or action by the holders of Southern Union common stock, has
the authority, subject to certain limitations, to issue up to an aggregate of
6,000,000 shares of Southern Union preferred stock in one or more classes or
series, and to determine the designation and the number of shares of any class
or series and to fix the designation, powers, preferences and rights of each

                 COMPARISON OF FALL RIVER GAS AND 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 is a Massachusetts corporation. The rights of a
holder of Fall River Gas common stock are governed by Fall River Gas' restated
articles of organization and bylaws. In addition, Chapter 164 of the
Massachusetts General Laws ("MGL, Chapter 164") provides that the rights of
stockholders of Massachusetts gas companies, such as Fall River Gas, 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 its merger with Fall River Gas and Southern Union's restated
certificate of incorporation and bylaws will survive rather than those of Fall
River 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
shareholder 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 Chapter 164
which are applicable to Massachusetts gas companies subject to that Chapter.
Neither the Massachusetts Department of Telecommunications and Energy
("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.

There are also differences between the restated certificate of incorporation
and bylaws of Southern Union and the articles of organization and bylaws of
Fall River Gas. As a result, the rights of a holder of Southern Union common
stock differ from the rights of a holder of Fall River Gas common stock.

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 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.

The following information is a summary of some of the important differences
between the DGCL and the restated certificate of incorporation and bylaws of
Southern Union, on one hand, and the MGL, Chapter 164 and the articles of
organization and bylaws of Fall River Gas, on the other. The provisions of the
MGL, Chapter 164, that could be applicable to Southern Union after the merger
are highlighted in the right hand columns of this summary. This summary does
not purport to be a complete discussion of, and is qualified in its entirety
by reference to, the DGCL and MGL, Chapter 164, as well as the restated
certificate of

                                      83

incorporation and bylaws of Southern Union and the articles of organization
and bylaws of Fall River Gas, copies of which are on file with the SEC.

Southern Union board. Dividends may be paid
upon common stock as and when declared by the
Southern Union board, subject to all of the rights of
the preferred stockholders. See "Description of
Southern Union Capital Stock - Southern Union
Preferred Stock."

In addition, the DGCL generally provides that a
corporation may redeem or repurchase its shares
only if such redemption or repurchase would not
impair the capital of the corporation. The ability of
a Delaware corporation to pay dividends on, or to
make repurchases or redemptions of, its shares is
dependent on the financial status of the corporation
standing alone and not on a consolidated basis. In
determining the amount of surplus of a Delaware
corporation, the assets of the corporation, including
stock of subsidiaries owned by the corporation,
must be valued at their fair market value as deter-
mined by the Southern Union board, regardless of
their historical book value.

In addition, the DGCL provides that a parent
corporation that is the record holder of at least 90%
of the outstanding shares of each class of stock of
a subsidiary may merge such subsidiary into such
parent corporation without the approval of such
subsidiary's stockholders or board and without the
approval of the parent's stockholders.

                          PROPOSALS OF STOCKHOLDERS

We expect the merger to be completed before Fall River Gas would have its next
annual meeting of stockholders in 2001. If the merger is not completed by
then, and if a stockholder intends to present a proposal at the Fall River
Gas' 2000 annual meeting of stockholders and wants that proposal to be
included in the Fall River Gas' proxy statement and form of proxy for that
meeting, the proposal must be received by the Office of the Clerk, Fall River
Gas, 155 North Main Street, P.O. Box 911, Fall River, Massachusetts 02722-0911
by August 18, 2000. The proxies named in management's proxy for that meeting
will be entitled to exercise their discretionary authority on any proposal,
which a stockholder intends to present to stockholders, that was not included
in the Fall River Gas' proxy statement for the 2001 annual meeting, unless
Fall River Gas receives notice of the matter to be proposed before November 1,
2000. Even if proper notice is received on or prior to November 1, 2000, the
proxies named in management's proxy for that meeting may nevertheless exercise
their discretionary authority with respect to such matter by advising
stockholders of such proposals and how they intend to exercise their
discretion to vote on such matter, unless the stockholder making the proposal
solicits proxies with respect to the proposal as detailed in Rule 14a-4(c)(2)
of the Securities Exchange Act of 1934.

                                  OTHER MATTERS

Except for the matters set forth above, the board of directors knows of no
other matters which may be presented to the special meeting of stockholders,
but if any other matters properly come before such meeting, it is the
intention of the persons named in the accompanying form of proxy to vote such
proxies in accordance with their judgment.

                           THE MERGER; OTHER TRANSACTIONS

     SECTION 2.1    THE MERGER.  Upon the terms and subject to the conditions of
this Agreement, at the Effective Time,  FAL will be merged with and into SUG in
accordance with the laws of the State of Delaware and the Commonwealth of
Massachusetts.  SUG will be the surviving corporation in the Merger (the
"Surviving Corporation") and will continue its corporate existence under the
laws of the State of Delaware.  The Merger will have the effect as provided in
the applicable provisions of the DGCL and the MBCL. Without limiting the
generality of the foregoing, upon the Merger, all the rights, privileges,
immunities, powers and franchises of FAL and SUG will vest in the Surviving
Corporation and all

                                     A-8

<PAGE>

obligations, duties, debts and liabilities of FAL and SUG will be the
obligations, duties, debts and liabilities of the Surviving Corporation.

     SECTION 2.2    EFFECTIVE TIME OF THE MERGER.  On the Closing Date, with
respect to the Merger, (i) a duly executed certificate of merger complying
with the requirements of the DGCL will be executed and filed with the
Secretary of State of the State of Delaware and (ii) duly executed articles
of merger complying with the requirements of the MBCL will be filed with the
Secretary of State of the Commonwealth of Massachusetts.  The Merger will
become effective upon filing the certificate of merger with the Secretary of
State of the State of Delaware and the articles of merger with the Secretary
of State of the Commonwealth of Massachusetts (the "Effective Time").

     SECTION 2.3    CLOSING.  Unless this Agreement has been terminated and
the transactions contemplated herein have been abandoned pursuant to Article
VIII hereof, the closing of the transactions contemplated by this Agreement
(the "Closing") will take place at 10:00 a.m., Eastern Time, on the Closing
Date to be specified by the parties, which shall be no later than the tenth
business day after satisfaction or waiver of all of the conditions set forth
in Article VII hereof (other than Sections 7.1(a), 7.1(b), 7.1(c), 7.1(f),
7.1(g), 7.1(h), 7.1(k), 7.1(l), 7.2(a), 7.2(b), 7.2(c), 7.2(e), 7.2(f) and
7.2(h), which shall be satisfied or waived on the Closing Date) at the
offices of Hughes Hubbard & Reed LLP, New York, counsel to SUG, unless
another date or place is agreed to in writing by the parties hereto.

     SECTION 2.4    CERTIFICATE OF INCORPORATION; BYLAWS.  Pursuant to the
Merger, the Restated Certificate of Incorporation of SUG, as in effect
immediately prior to the Effective Time, shall be the Certificate of
Incorporation of the Surviving Corporation until thereafter amended as
provided by law and (ii) the bylaws of SUG as in effect immediately prior to
the Effective Time, shall be the bylaws of the Surviving Corporation until
thereafter amended as provided by law.

     SECTION 2.5    DIRECTORS AND OFFICERS.  The directors and officers of
SUG immediately prior to the Effective Time will be the directors and
officers of the Surviving Corporation, each to hold office in accordance with
the Certificate of Incorporation and bylaws of the Surviving Corporation.

                                    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.

                                     A-9

<PAGE>

     "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.

          (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.


                                     A-10

<PAGE>

          (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 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

                                     A-11

<PAGE>

"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 f 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

                                     A-12

<PAGE>

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 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

                                     A-13

<PAGE>

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 Common Stock or other capital
stock of SUG or any of its material Subsidiaries, (ii) warrants or options to
purchase SUG Common Stock or other securities of SUG or any of its material
Subsidiaries or (iii) commitments to issue shares of SUG Common Stock (other
than pursuant to the Merger and other than pursuant to the Agreement of
Merger, dated as of June 7, 1999 (the "PEI Merger Agreement"), by and between
SUG and Pennsylvania Enterprises, Inc. ("PEI")) or other securities of SUG or
any of its material Subsidiaries.

     SECTION 4.3    SUBSIDIARIES; INVESTMENTS.  Except as set forth in
Section 4.3 of the SUG Disclosure Schedule, as of the date of this Agreement,
SUG has no Subsidiaries or investments in any Person except for marketable
securities reflected in the SUG SEC Documents delivered to FAL prior to the
date of this Agreement, and SUG is the registered owner and holder of all of
the issued and outstanding shares of capital stock of its Subsidiaries and
has good title to such shares.  The outstanding capital stock of each
material Subsidiary of SUG has been validly issued and is fully paid and
nonassessable.

     SECTION 4.4    AUTHORITY RELATIVE TO THIS AGREEMENT AND BINDING EFFECT.
The execution, delivery and performance of this Agreement and the Related
Documents by SUG have been duly authorized by all requisite corporate action.
The execution, delivery and performance of this Agreement and the Related
Documents by SUG will not result in a violation or breach of any term or
provision of, constitute a default, or require a consent, approval or
notification, or accelerate the performance required under, the
Organizational Documents of SUG, any indenture, mortgage, deed of trust,
security agreement, loan agreement, or other Contract to which SUG is a party
or by which its assets are bound, or violate any Order, with such exceptions
as are not, individually or in the aggregate, reasonably likely to have a SUG
Material Adverse Effect. This Agreement constitutes and the Related Documents
to be executed by SUG when executed and delivered will constitute valid and
binding obligations of SUG, enforceable against SUG in accordance with their
terms, except as enforceability may be limited by (i) bankruptcy or similar
laws from time to time in effect affecting the enforcement of creditors'
rights generally or (ii) the availability of equitable remedies generally.

     SECTION 4.5    GOVERNMENTAL APPROVALS.  Except as set forth in Section
4.5 of the SUG Disclosure Schedule and as required by the HSR Act, no
approval or authorization of any Governmental Body with respect to
performance under this Agreement or the Related Documents by SUG is required
to be obtained by SUG in connection with the execution and delivery by SUG of
this Agreement or the Related Documents or the consummation by SUG of the
transactions contemplated hereby or thereby, the failure to obtain which are,
individually or in the aggregate, reasonably likely to have a SUG Material
Adverse Effect.

     SECTION 4.6    PUBLIC UTILITY HOLDING COMPANY STATUS; REGULATION AS A
PUBLIC UTILITY.  SUG is a "gas utility company" (as such term is defined in
PUHCA).  SUG indirectly owns a minority interest in a "foreign utility
company" (as such term is defined in PUHCA) that is exempt from, and is
deemed not to be a public utility company for purposes of, PUHCA pursuant to
Section 33 thereof with respect to which SUG has filed with the SEC a Form
U-57 notification of foreign utility company status.  Except as stated above
in this Section 4.6, neither SUG nor any of its Subsidiaries is a "holding
company," a "subsidiary company," a "public utility company" or an
"affiliate" of a "public utility company," or a "holding company" within the
meaning of such terms in PUHCA.

     SECTION 4.7    COMPLIANCE WITH LEGAL REQUIREMENTS; GOVERNMENTAL
AUTHORIZATIONS.

                                     A-14

<PAGE>

          (a)  Except as set forth in Section 4.7 of the SUG Disclosure
Schedule or specifically described in the SUG SEC Documents delivered to FAL
prior to the date of this Agreement, and subject to Section 4.15 of this
Agreement, to the Knowledge of SUG, SUG is not in violation of any Legal
Requirement that is applicable to it, to the conduct or operation of its
business, or to the ownership or use of any of its assets, other than such
violations, if any, which are not, individually or in the aggregate,
reasonably likely to have a SUG Material Adverse Effect.

          (b)  The SUG SEC Documents delivered to FAL prior to the date of
this Agreement accurately describe all material regulation of SUG that
relates to the utility business of SUG as of the date of this Agreement.
Except as set forth in Section 4.7 of the SUG Disclosure Schedule, SUG has,
and is in material compliance with, all material Governmental Authorizations
necessary to conduct its business and to own, operate and use all of its
assets as currently conducted.

     SECTION 4.8    LEGAL PROCEEDINGS; ORDERS.  Except as set forth in
Section 4.8 of the SUG Disclosure Schedule or as specifically described in
the SUG SEC Documents delivered to FAL prior to the date of this Agreement,
there is no pending Proceeding:

               (1)  that has been commenced by or against, or that otherwise
          relates to, SUG or, if the merger with PEI is consummated, PEI, that
          is reasonably likely to have a SUG Material Adverse Effect; or

               (2)  as of the date of this Agreement, that challenges, or that
          may have the effect of preventing, delaying, making illegal, or
          otherwise interfering with, the Merger or any of the transactions
          contemplated hereby.

To the Knowledge of SUG, no such Proceedings, audits or investigations have
been Threatened that are, individually or in the aggregate, reasonably likely
to have a SUG Material Adverse Effect.  As of the date of this Agreement, SUG
is not subject to any Orders that are, individually or in the aggregate,
reasonably likely to have a SUG Material Adverse Effect.

     SECTION 4.9    SEC DOCUMENTS.  SUG has made (and, with respect to such
documents filed after the date hereof through the Closing Date, will make)
available to FAL a true and complete copy of each report, schedule,
registration statement (other than on Form S-8), and definitive proxy
statement filed by SUG with the SEC since September 16, 1999 and through the
Closing Date in substantially the form filed with the SEC (the "SUG SEC
Documents").  As of their respective dates, the SUG SEC Documents, including
without limitation any financial statements or schedules included therein,
complied (or will comply), in all material respects with the requirements of
the Securities Act or the Exchange Act, as the case may be, and the rules and
regulations of the SEC thereunder applicable to such SUG SEC Documents, and
did not (or will not) contain any untrue statement of a material fact or omit
to state a material fact required to be stated therein or necessary to make
the statements therein, in light of the circumstances under which they were
made, not misleading.  The audited consolidated financial statements and
unaudited interim financial statements of SUG included in the SUG SEC
Documents (collectively, the "SUG Financial Statements") were (or will be)
prepared in accordance with GAAP applied on a consistent basis (except as may
be indicated therein or in the notes thereto and except with respect to
unaudited statements as permitted by Form 10-Q) and fairly present (or will
fairly present) in all material respects the financial position of

                                     A-15

<PAGE>

SUG as of the respective dates thereof or the results of operations and cash
flows for the respective periods then ended, as the case may be, subject, in
the case of unaudited interim financial statements, to normal, recurring
adjustments which are not material in the aggregate.

are reputable insurers against all risks and in such amounts normally insured
against by companies of the same type and in the same line of business as any of
the Acquired Companies.  As of the date of this Agreement, no notice of
cancellation, non-renewal or material increase in premiums has been received by
any of the Acquired Companies with respect to such policies, and no Acquired
Company has Knowledge of any fact or circumstance that could reasonably be
expected to form the basis for any cancellation, non-renewal or material
increase in premiums, except for such cancellations, non-renewals and increases
which are not, individually or in the aggregate, reasonably likely to have a FAL
Material Adverse Effect.  None of the Acquired Companies is in default with
respect to any provision contained in any such policy or binder nor has there
been any failure to give notice or to present any claim relating to the business
or the assets of the Acquired Companies under any such policy or binder in a
timely fashion or in the manner or detail required by the policy or binder,
except for such defaults or failures which are not, individually or in the
aggregate, reasonably likely to have  a FAL Material Adverse Effect.  As of the
date of this Agreement, there are no outstanding unpaid premiums (except
premiums not yet due and payable), and no notice of cancellation or renewal with
respect to, or disallowance of any claim under, any such policy or binder has
been received by the Acquired Companies as of the date hereof, except for such
non-payments of premiums, cancellations, renewals or disallowances which are
not, individually or in the aggregate, reasonably likely to have a FAL Material
Adverse Effect.

Agreement of all the present officers and employees of the Acquired Companies,

which would not be payable or provided in the absence of the consummation of the
transactions contemplated by this Agreement.

          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

               (1)  FAL shall not, and shall not authorize or permit any of its
          (or any of its Subsidiaries') officers, directors, agents, financial
          advisors, attorneys, accountants or other Representatives to, directly
          or indirectly, solicit, initiate 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 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 FAL Stockholders' Approval, FAL
          may, in response to an unsolicited written proposal from a third party
          with respect to a Business 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


                                    A-33
<PAGE>

          (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 permitted by this
          Agreement) (A) a merger, consolidation 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 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.

          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

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

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

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

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

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 tatement 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

                                    A-38
<PAGE>

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 or desirable to carry out the purpose of this Agreement and to
vest the Surviving Corporation with full right, title and possession to all
assets, property, rights, privileges, powers and franchises of the Acquired
Companies, the officers and directors of the Surviving Corporation 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, FAL

pursuant to Section 8.1, this Agreement shall be of no further force and

party or its Affiliates, directors, officers, stockholders, agents or other
Representatives; PROVIDED, HOWEVER, that (i) any fee payable under Section

liability for any claims, damages or losses suffered by the other party as a
result of the negligent or willful failure of a party to perform any
obligations required to be performed by it hereunder on or prior to the date
of termination. Notwithstanding anything to the contrary contained herein,
the provisions of Section 8.2, Sections 10.1 through 10.6 and Sections 10.8

Agreement.

          (b)  EXPENSES.  The parties agree that the agreements contained in
this Section 8.3 are an integral part of the transactions contemplated by

Notwithstanding anything to the contrary contained in this Section 8.3, if
FAL fails to pay promptly to SUG the fee due under Section 8.3(a), in
addition to any amounts paid or payable pursuant to Section 8.3(a), FAL shall
pay the costs and expenses (including legal fees and expenses) in connection
with any action, including the filing of any lawsuit or other legal action,
taken to collect payment, together with interest on the amount of any unpaid
fee calculated using an annual percentage rate of interest equal to the prime
rate published in the WALL STREET JOURNAL on the date (or preceding business
day if such date is not a business day) such fee was required to be paid,
compounded on a daily basis using a 360-day year.

                             INDEMNIFICATION; REMEDIES

     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

                                       A-43

<PAGE>

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.

                                     ARTICLE X

             [LEGG MASON WOOD WALKER, INCORPORATED LETTERHEAD]




                              October 4, 1999


The Board of Directors
Fall River Gas Company
155 North Main Street
Fall River, Massachusetts 02720
               Attention: Bradford J. Faxon


Members of the Board of Directors:

     We are advised that Fall River Gas Company (collectively, "Fall River"
or the "Company") has entered into an Agreement of Merger (the "Agreement")
with Southern Union Company ("Southern Union"), pursuant to which Fall River
will merge into Southern Union and each outstanding share of Fall River
common stock will be converted into the right to receive $23.50 in cash or in
value of common stock of Southern Union on terms and conditions as more fully
set forth in the Agreement (the transaction is referred to herein as the
"Transaction").

     You have requested our opinion, as investment bankers, as to the
fairness to the shareholders of the Company, from a financial point of view,
of the consideration to be received by the shareholders of the Company in the
Transaction.

     For purposes of rendering this opinion, we have, among other things:

     (i)    reviewed the form of the definitive Agreement and certain related
            documents;

     (ii)   reviewed the audited consolidated financial statements of Fall
            River for the twelve month periods ended September 30, 1998, 1997,
            1996 and 1995;

     (iii)  reviewed the unaudited financial statements of Fall River for the
            nine month period ended June 30, 1999;

     (iv)   reviewed the audited consolidated financial statements of Southern
            Union for the twelve month periods ended June 30, 1999, 1998, 1997,
            1996 and 1995;

     (v)    reviewed certain publicly available information concerning Fall
            River and Southern Union;


                                     B-1
<PAGE>


     (vi)   reviewed forecast financial statements of Fall River furnished to
            us by the senior management of Fall River;

     (vii)  reviewed and analyzed certain publicly available financial and
            stock market data with respect to operating statistics relating to
            selected public companies that we deemed relevant to our inquiry;

     (viii) reviewed the reported prices and trading activity of the
            publicly-traded securities of Fall River and Southern Union;

     (ix)   analyzed certain publicly available information concerning the
            terms of selected merger and acquisition transactions that we
            considered relevant to our inquiry;

     (x)    held meetings and discussions with certain officers and employees
            of Fall River and Southern Union concerning the operations,
            financial condition and future prospects of Fall River and
            Southern Union; and

     (xi)   conducted such other financial studies, analyses and investigations
            and considered such other information as we deemed necessary or
            appropriate for purposes of our opinion.

     In connection with our review, we have assumed and relied upon the
accuracy and completeness of all financial and other information supplied to
us by Southern Union and Fall River or publicly available, and we have not
independently verified such information.  We have further relied upon the
assurances of management of Southern Union and Fall River that they are
unaware of any facts that would make such information incomplete or
misleading.  We also have relied upon the managements of Southern Union and
Fall River, as to the reasonableness and achievability of the financial
projections (and the assumptions and bases therein) provided to us or
prepared for Fall River and Southern Union, and we have assumed that such
projections have been reasonably prepared on bases reflecting the best
currently available estimates and judgments of management as to the future
operating performance of Fall River and Southern Union, including without
limitation the tax benefits, cost savings and operating synergy to be enjoyed
by Southern Union after the Transaction.  Neither Southern Union nor Fall
River publicly discloses internal management projections of the type provided
to Legg Mason in connection with Legg Mason's review of the Transaction.
Such projections were not prepared with the expectation of public disclosure.
 The projections were based on numerous variables and assumptions that are
inherently uncertain, including without limitation, factors related to
general economic and competitive conditions.  Accordingly, actual results
could vary significantly from those set forth in such projections.

We have not been requested to make, and have not made, an independent
appraisal or evaluation of the assets, properties or liabilities of Fall
River and we have not been furnished with any such appraisal or evaluation.
We have not reviewed any of the books and records of Fall River or assumed
any responsibility for conducting a physical inspection of the properties or
facilities of Fall River.  Further, this opinion is based upon prevailing
market conditions and other circumstances and conditions existing on the date
hereof.  We have assumed that the


                                     B-2
<PAGE>


Transaction will be consummated on the terms and conditions described in the
form of the Agreement reviewed by us.  It is understood that subsequent
developments may affect the conclusions reached in this opinion and that we
do not have any obligation to update, revise or reaffirm this opinion.

     It is understood that this letter is directed to the Company's Board of
Directors.  The opinion expressed herein is provided for the use of the
Company's Board of Directors in its evaluation of the proposed Transaction
and does not constitute a recommendation to any shareholder of the Company
either of the Transaction or as to how such shareholder should vote on or
otherwise respond to the Transaction.  In addition, this letter does not
constitute a recommendation of the Transaction over any other alternative
transaction which may be available to the Company and does not address the
underlying business decision of the Board of Directors of the Company to
proceed with or effect the Transaction.  This letter is not to be quoted or
referred to, in whole or in part, in any registration statement, prospectus
or proxy statement, or in any other document used in connection with the
offering or sale of securities, nor shall this letter be used for any other
purposes, without the prior written consent of Legg Mason Wood Walker,
Incorporated; provided that this Opinion may be included in its entirety in
any filing made by the Company with the Securities and Exchange Commission
with respect to the Transaction.

     Legg Mason will receive a fee for providing this Opinion to the Board of
Directors of Fall River.  Legg Mason has previously provided a fairness
opinion to a company that has agreed to be acquired by Southern Union.

     Based upon and subject to the foregoing, we are of the opinion that, as
of the date hereof, the consideration to be received by the shareholders of
Fall River in the Transaction is fair to such shareholders from a financial
point of view.

                                   Very truly yours,

                                   LEGG MASON WOOD WALKER, INCORPORATED

                                 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


                                     C-1
<PAGE>


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 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


                                     C-2
<PAGE>


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


                                     C-3
<PAGE>


(but not limited to) an injunction or order of specific performance of the
terms hereof from a court of competent jurisdiction.

         11.  AMENDMENTS.  This Agreement may not be modified, amended,
altered or supplemented except upon the execution and delivery of a written
agreement executed by all of the parties hereto.

         12.  NOTICES.  All notices, requests, claims, demands and other
communications hereunder shall be in writing and shall be deemed given if

               FORM OF VOTING AGREEMENT AND IRREVOCABLE PROXY

Ladies and Gentlemen:

         Reference is made to the Agreement and Plan of Merger among Southern
Union Company ("Southern Union"), and Fall River Gas Company ("Fall River"),
dated as of  October 4,1999 (as amended, supplemented or otherwise modified
from time to time, the "Merger Agreement").

         In connection therewith, the undersigned agrees, upon each and every
oral or written request or direction by Fall River, and in accordance with
such request or direction, (a) to vote each of the shares of common stock
(par value $.83 1/3 per share) of Fall River beneficially owned by the
undersigned (the "Shares") entitled to vote as of the record date for the
Special Meeting of Shareholders of Fall River called for the purpose of
voting on the Merger Agreement, either in person or by proxy, in favor of the
approval of the Merger Agreement and the transactions contemplated thereby
and (b) to vote the Shares, either in person or by proxy, on any other matter
that is not inconsistent with the Merger Agreement and the transactions
contemplated thereby submitted to Fall River's shareholders for approval in
the same proportion as the votes cast by the shareholders of Fall River other
than Southern Union. The undersigned irrevocably appoints each of Bradford J.
Faxon and Peter H. Thanas attorney-in-fact and proxy of the undersigned, with
full power of substitution, to vote the Shares on its behalf pursuant to the
preceding sentence. This appointment is effective upon execution of this
proxy and shall be valid until (A) in the case of clause (a) of the second
preceding sentence, the earlier to occur of (i) the termination of the Merger
Agreement in accordance with its terms or (ii) the


                                     D-1

consummation of the transactions contemplated by the Merger Agreement and (B)
in the case of clause (b) of the second preceding sentence, the earliest to
occur of (i) February 28, 2001, (ii) the sale of the Shares to one or more
parties unaffiliated with Southern Union in open market transactions or (iii)
the consummation of the transactions contemplated by the Merger Agreement.
This proxy is irrevocable and shall be deemed to be coupled with an interest.
The execution of this proxy shall revoke all prior proxies or written
consents given by the undersigned at any time with respect to the Shares and
no subsequent proxies or written consents may be given (and if given will be
deemed not to be effective) by the undersigned with respect to the Shares.

         The undersigned hereby represents and warrants that the undersigned
has full power and authority to execute this proxy, and has, or will have,
good and unencumbered title to the Shares, free and clear of all liens,
restrictions, charges and encumbrances, and not subject to any adverse claim,
in any such case that would preclude the effectiveness of this proxy. The
undersigned will, upon request, execute and deliver any additional documents
and take such further actions necessary or desirable to carry out the
purposes of the proxy. All authority conferred or agreed to be conferred in
this proxy shall be binding upon the successors, assigns, executors,
administrators, trustees in bankruptcy and legal representatives of the
undersigned.
