                             VALLEY RESOURCES, INC.

     The accompanying proxy will be mailed to our stockholders together with the
Notice of Special Meeting and this proxy statement on or about May 9, 2000. We
are soliciting this proxy in connection with the Special Meeting to be held on
June 13, 2000. ("We" and "our" as used in this document refer to Valley
Resources.)

                               SUMMARY TERM SHEET

     We are asking you to approve and adopt the merger agreement that will
result in us becoming a wholly-owned subsidiary of Southern Union. When we speak
about the "merger" and the "merger agreement" in this proxy statement, we mean
the merger of SUG Acquisition Corporation into us and the agreement that sets
forth the details of the merger. While we have summarized the terms of the
merger below, we have attached the merger agreement at the back of this proxy
statement as Appendix A. We encourage you to read the merger agreement since it
is the legal document that governs the merger.

     - MERGER CONSIDERATION:  As a result of the merger, each share of our
       common stock that you own will be converted into the right to receive
       $25.00 in cash. See "The Merger Agreement -- Merger Consideration" for
       additional information.

     - TAX CONSEQUENCES:  As a result of the merger, our stockholders will
       generally recognize capital gains for U.S. federal income tax purposes
       for the cash received in the merger. The capital gains will be equal to
       the amount of cash received in the merger exceeding the tax basis our
       stockholders have in our common stock. The merger will not result in
       recognition of gain or loss to Southern Union, to us or to our
       subsidiaries. See "The Merger -- Significant U.S. Federal Income Tax
       Consequences of the Merger" for additional information.

     - STRUCTURE OF THE MERGER:  At the time the merger becomes effective, SUG
       Acquisition Corp., a wholly-owned subsidiary of Southern Union, will
       merge into us. As a result, we will become a wholly-owned subsidiary of
       Southern Union. See "The Merger Agreement -- Structure of the Merger" for
       additional information.

     - SUBSIDIARY MERGERS:  Immediately after the merger, Valley Gas Company and
       Bristol and Warren Gas Company, our wholly-owned subsidiaries, will merge
       into us. We call these mergers the "subsidiary mergers." Immediately
       after the subsidiary mergers, we will merge into Southern Union. At that
       time, our utility operations will become a division of Southern Union and
       our non-utility subsidiaries will become subsidiaries of Southern Union.
       See "The Merger Agreement -- Subsidiary Mergers" for additional
       information.

     - CONFLICTS OF INTEREST:  Our officers and members of our board have
       interests in the merger that may be different from your interests and may
       represent conflicts of interest. For example:

        - The merger will constitute a "change of control" that will entitle
          certain officers to receive severance benefits if Southern Union
          terminates the officer without cause or if the officer terminates his
          or her own employment as a result of the change of control.

        - Alfred P. Degen, our Chairman, President and Chief Executive Officer,
          has entered into an employment agreement with Southern Union that will
          become effective upon completion of the merger.

        - For six years after the merger, Southern Union will indemnify and
          provide liability insurance for our current officers and directors for
          acts or omissions that may have occurred before the merger.

        See "The Merger -- Potential Conflicts and Interests of Certain Persons
        in the Merger" for additional information.

     - CONDITIONS OF CLOSING:  Before the merger can become effective, certain
       conditions must be satisfied or waived, including:

        - Approval by our stockholders.

                                        1
<PAGE>   6

        - The public utility regulators of Rhode Island, Massachusetts,
          Pennsylvania, Missouri and Florida must approve the merger or related
          financing arrangements without imposing any material adverse
          conditions.

        - Expiration of the applicable waiting period under the
          Hart-Scott-Rodino Antitrust Improvements Act of 1976.

        - The Rhode Island Legislature must amend the legislative charters of
          Valley Gas and Bristol and Warren Gas to complete the subsidiary
          mergers.

        - No court or administrative orders to prevent the merger.

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

        - Certain other conditions that have already been satisfied.

        See "The Merger -- Regulatory Matters" and "The Merger
        Agreement -- Conditions to the Completion of the Merger" for additional
        information.

     - TERMINATION OF MERGER AGREEMENT:  We and Southern Union may terminate the
       merger agreement if we jointly agree to do so. In addition, either we or
       Southern Union may terminate the merger agreement if:

        - the merger is not completed by February 28, 2001 (this date may be
          extended to May 31, 2001 to obtain government approvals); or

        - we do not obtain stockholder approval of the merger; or

        - certain other circumstances occur as described in "The Merger
          Agreement -- Termination of the Merger Agreement."

     - TERMINATION FOR FIDUCIARY REASONS:  Our board of directors may terminate
       the merger agreement if it determines that termination is necessary for
       our board to uphold its fiduciary duties to our stockholders. Southern
       Union may terminate the merger agreement if our board of directors fails
       to recommend approval of the merger agreement to our stockholders. In
       either of these events, we may be required to pay Southern Union a
       termination fee of $5 million. See "The Merger Agreement -- Termination
       of the Merger Agreement" for additional information.

     - AMENDMENT OF MERGER AGREEMENT:  We and Southern Union may amend any of
       the terms of the merger agreement. See "The Merger
       Agreement -- Amendments" for additional information.

     - BOARD RECOMMENDATION:  Our board of directors believes that the merger is
       in the best interest of our stockholders and recommends that you vote
       "FOR" the approval and adoption of the merger agreement. See "The
       Merger -- Reasons for the Merger; Recommendation of Our Board of
       Directors" for additional information.

     - FAIRNESS OPINION:  In deciding to approve the merger, our board of
       directors considered an opinion from our financial advisor, PaineWebber
       Incorporated. The opinion stated that as of the date of the merger
       agreement, the consideration to be received by our stockholders was fair
       to our stockholders from a financial point of view. We have attached a
       copy of this opinion to the proxy statement as Appendix B. We encourage
       you to read this opinion. See "The Merger -- Opinion of Our Financial
       Advisor" for additional information.

                     QUESTIONS AND ANSWERS ABOUT THE MERGER

Q:  What do I need to do now?

A: You should carefully read and consider the information contained in this
   document. You should complete and sign your proxy and return it in the
   enclosed return envelope as soon as possible so that your shares may be
   represented at the special meeting. You may also vote via the Internet, as we
   describe in this proxy statement. If you fail to vote in person or by proxy,
   this 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 a
   majority of shares of our common stock entitled to vote at the special
   meeting.

Q:  Who is entitled to vote?

A: Stockholders as of the close of business on the record date, April 28, 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: 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.

   You can also deliver a later-dated, signed proxy card or send a written
   notice stating you would like to revoke your proxy before the special
   meeting. These should be sent to: Valley Resources, Inc., 1595 Mendon Road,
   Cumberland, Rhode Island 02864, Attention: Secretary. This notice must reach
   the Secretary before the proxy is voted. You may also change your vote prior
   to the special meeting via the Internet.

Q:  My shares are held in "street name." Will my broker vote my shares on the
merger agreement?

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 dissenters' rights?

A: No, Rhode Island law does not provide for dissenters' rights for
   publicly-traded companies.

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 for the cash
   consideration. 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 our Secretary at

   end of the third calendar quarter of 2000.

           CAUTIONARY STATEMENT REGARDING FORWARD-LOOKING STATEMENTS

     Valley Resources and our subsidiaries and representatives may from time to
time make written or oral statements, including statements contained in filings
with the Securities and Exchange Commission, which constitute forward-looking
statements.

     All statements other than statements of historical facts included in this
proxy statement regarding our financial position and strategic initiatives and
addressing industry developments are forward-looking statements. We may use the
words "believe," "anticipate," "expect," "intend" and similar expressions to
identify forward-looking statements. When, in any forward-looking statement, we
express an expectation or belief as to future results, this expectation or
belief is expressed in good faith and believed to have a reasonable basis, but
there can be no assurance that the statement of expectation or belief will
result or be achieved or accomplished.

     Forward-looking statements are subject to a number of risks, assumptions
and uncertainties. The following are some of the factors which may cause actual
results to differ materially from those anticipated:

     - general economic, financial and business conditions,

     - changes in government regulations,

     - competition in the energy services sector,

     - regional weather conditions,

     - the availability and cost 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 ability to grow through acquisitions and/or significant customer
growth,

     - the costs and effects of unanticipated legal proceedings,

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

     - changes in business strategy.

     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 COMPANIES

SOUTHERN UNION

     Southern Union is a publicly owned international energy company
headquartered in Austin, Texas. It primarily engages in the distribution of
natural gas and is one of the fifteen largest distributors in the nation, as
measured by number of customers. Southern Union serves more than one million
customers through its four natural gas divisions in Texas, Missouri,
Pennsylvania and Florida, its propane distribution subsidiaries, and its equity
ownership in a natural gas distribution company serving Piedras-Negras, Mexico.
Through its subsidiaries, Southern Union also markets natural gas to end users
and operates natural gas pipeline systems.

     Southern Union has a goal of selected growth and expansion, primarily in
the utilities industry. To that extent, it 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 board of directors. Acquisitions, including the proposed mergers
with Fall River Gas Company, Providence Energy Corporation and Valley Resources,
require substantial additional financing through future debt, and possibly
future equity, offerings. The availability and terms of any such financing
sources will depend upon various factors and conditions, such as Southern
Union's cash flow and earnings, its resulting capital structure, its credit
ratings and conditions in financial capital markets at the time of any such
offering.

     The address of the principal offices of Southern Union is 504 Lavaca, Suite
800, Austin, Texas 78701. Their phone number is (512) 477-5852.

     Merger with Pennsylvania Enterprises, Inc.  Effective November 4, 1999,
Southern Union acquired Pennsylvania Enterprises, Inc. ("PEI") (formerly, NYSE:
PNT) 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 and Honesdale Gas, a division of Southern Union,
which provides service to approximately 152,000 natural gas customers in
northeastern and central Pennsylvania (including the cities of Wilkes-Barre,
Scranton and Williamsport). Through the acquisition of PEI, Southern Union
acquired and now operates a subsidiary that markets electricity and other
products and services under the name PG Energy Power Plus, principally in
northeastern and central Pennsylvania. Other subsidiaries that Southern Union
acquired in the PEI merger engage in various non-regulated activities, including
the construction, maintenance and rehabilitation of natural gas distribution
pipelines.

     Pending Merger with Fall River Gas Company.  On October 4, 1999, Southern
Union and Fall River Gas Company (AMEX:FAL) entered into a merger agreement. The
Fall River Gas merger agreement calls for Southern Union to acquire Fall River
Gas in a transaction valued at approximately $75 million, including assumption
of debt. Fall River Gas shareholders will receive $23.50 for each share of Fall
River Gas common stock they own. The Fall River Gas merger agreement provides
that Fall River Gas shareholders can elect to receive Southern Union common
stock, cash or a combination of stock and cash, subject to proration and an
adjustment formula. At least 50% of the approximately 2.2 million outstanding
shares of Fall River Gas common stock must be converted into Southern Union
common stock and up to the remaining 50% of Fall River Gas shares will be
converted into cash. The exchange ratio for the stock portion of the
consideration will be calculated prior to the completion of the merger based on
recent trading prices before then. Headquartered in Fall River, Massachusetts,
Fall River Gas serves approximately 48,000 customers in the city of Fall River
and the towns of Somerset, Swansea and Westport, all located in southeastern
Massachusetts. Southern Union anticipates completing the Fall River Gas merger
in late summer or early fall 2000 after customary closing conditions and
prerequisites are satisfied, including Southern Union and Fall River Gas
shareholder approval and receipt of all regulatory approvals for the Fall River
Gas merger.

     Pending Merger with Providence Energy Corporation.  On November 14, 1999,
Southern Union entered into a merger agreement to acquire Providence Energy
Corporation (NYSE:PVY) for $42.50 in cash for each of Providence Energy's
approximately 6.1 million shares outstanding, plus the assumption of
approximately $140 million of debt securities. Providence Energy, headquartered
in Providence, Rhode Island, is engaged

                                        6
<PAGE>   11

through its subsidiaries principally in natural gas distribution to
approximately 166,000 natural gas customers in Providence and Newport, Rhode
Island, and 23 other cities and towns in Rhode Island and Massachusetts.
Providence Energy's oil business serves over 4,000 residential customers and a
larger commercial base. Providence Energy's utility service territories
encompass approximately 730 square miles with a population of approximately
817,000. Southern Union anticipates completing the Providence Energy merger in
late summer or early fall 2000 once all conditions are satisfied, including
Southern Union and Providence Energy shareholder approval and receipt of all
regulatory approvals.

                              THE SPECIAL MEETING

PURPOSE, TIME AND PLACE

     The special meeting will be held at our principal offices, 1595 Mendon
Road, Cumberland, Rhode Island 02864-0700, on June 13, 2000 at 10:00 a.m.
(Eastern time), for the following purposes:

          (1) To approve and adopt the merger agreement; and

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

RECORD DATE; VOTING POWER; VOTE REQUIRED

     Our board of directors has fixed the close of business on April 28, 2000 as
the record date for the determination of holders of our common stock entitled to
notice of and to vote at the special meeting. There were 4,992,002 shares
outstanding and entitled to vote on April 28, 2000. A majority of the shares of
our 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 in order for a
quorum to be present for purposes of transacting business at the special
meeting. If a quorum is not present at the special meeting, we expect that the
meeting will be adjourned or postponed to solicit additional proxies. Holders of
record of our common stock on 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 of the merger agreement requires the
affirmative vote of a majority of the shares of our common stock outstanding on
the record date.

SHARE OWNERSHIP OF MANAGEMENT

     At the close of business on April 28, 2000, our directors and officers
beneficially owned and were entitled to vote approximately 69,627 shares of our
common stock, which represented approximately 1.4% of the shares outstanding on
that date. Each of those directors and officers has indicated his or her present
intention to vote, or cause to be voted, our common stock owned by him or her
"FOR" the proposal to approve and adopt the merger agreement at the special
meeting. See "Principal Stockholders" for additional information.

VOTING OF PROXIES

     If you attend the special meeting, you may vote by ballot. However, since
many stockholders may be unable to attend the special meeting, our board of
directors is soliciting proxies so that each stockholder at the close of
business on the record date has the opportunity to vote on the proposals to be
considered at the special meeting.

     Registered stockholders can simplify their voting and save us expense by
voting via the Internet. We provide Internet voting information on the proxy
card. A Control Number, located above your name and address on the right side of
the proxy card, is designed to verify your identity, allow you to vote your
shares and confirm that we have properly recorded your voting instructions.

     If you do not choose to vote by Internet, you may still return your proxy
card, properly signed, and we will vote the shares in accordance with your
directions. You can specify your choices by marking the appropriate boxes on
your proxy card. If you sign and return your proxy card without specifying
choices, we will vote the shares as recommended by our board of directors.
Abstentions marked on your proxy card are voted neither FOR nor AGAINST, but we
count these shares in determining a quorum for each of the proposals.
Abstentions have the effect of a vote against the merger agreement. If you do
vote by Internet, it is not necessary to return your proxy card.

     If you hold your shares through a bank or broker, follow the voting
instructions on the form you receive. Broker non-votes will be treated as shares
that are present and entitled to vote at the special meeting for purposes of
determining whether a quorum exists and will have the same effect as votes
against approval of the merger agreement. The availability of Internet voting
will depend on the bank's or broker's voting process.

                                        9
<PAGE>   14

     Your vote is important. We urge you to vote by Internet or by signing and
returning the accompanying proxy card whether or not you plan to attend the
special meeting. If you do attend the special meeting, you may vote by ballot,
thereby canceling any proxy previously given.

     If any other matters are properly presented at the special meeting for
consideration, the persons named in the enclosed form of proxy will have
discretion to vote on such matters by best judgment (unless you withhold
authorization to use such discretion). We are not aware of any matters expected
to be presented at the special meeting other than as described in the Notice of
Special Meeting.

VOTING SHARES HELD IN 401(k) EMPLOYEE STOCK OWNERSHIP PLAN

     If you are a participant in our 401(k) Employee Stock Ownership Plan, your
proxy card will serve as a voting instruction for the trustee of the plan for
the account registered in your name. If the trustee does not receive proxy
instructions from any participant it will vote in its discretion.

HOW TO REVOKE A PROXY

     You may revoke your proxy at any time before it is voted at the special
meeting by executing a later-dated proxy by Internet or mail, by voting in
person by ballot at the special meeting, or by filing a written notice of
revocation to the Secretary at our address listed on page 3 of this proxy
statement. The revocation will be effective when we receive your written notice.

SOLICITATION OF PROXIES

     We will bear the costs of this solicitation of proxies. In addition to
solicitation by mail, we may make arrangements with brokerage houses and other
custodians, nominees and fiduciaries to send material to their principals, and
we may reimburse them for their delivery expenses. In order to ensure a
sufficient presence of our stockholders to constitute a quorum, our officers,
employees and designated agents may, without additional compensation, request
the return of proxies, in person or by telephone or telegram. We have retained
Morrow & Co., Inc. to assist us in the solicitation of proxies at an anticipated
cost of $7,500, plus reimbursement of out-of-pocket expenses.

                                   THE MERGER

     This section of the proxy statement, as well as the next section entitled
"The Merger Agreement," describe 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. We urge you to read
the merger agreement in its entirety.

BACKGROUND OF THE MERGER

     For the last several years, our board of directors regularly reviewed
strategic options for increasing stockholder value. Among the options considered
during this time were:

     - remaining an independent and small-sized company primarily engaged in the
       business of gas distribution in northeastern and eastern Rhode Island;

     - growing the company through increased emphasis on diversification into
       non-regulated businesses;

     - looking for a merger partner of similar size; and

     - looking for a merger partner of larger size.

     We carefully followed recent developments in the gas and electric utility
industries that have substantially increased competition in those industries,
making it difficult for small and medium-sized utilities to compete as
effectively as larger utilities. Over the past several years, we developed and
implemented strategic plans to respond to the evolving competitive environment
as it affected us. Our management concluded that our competitive position and
growth prospects would be significantly enhanced by increasing the scale of our
operations and the size of our customer base, as well as an increased focus on
complementary nonutility activities. As a result, from time to time members of
our senior management had exploratory conversations with executives from other
regional utility companies about the possibility of business combinations or
other strategic transactions. None of these conversations led to any substantive
proposals.

     During the spring and early summer of 1999, the pace of consolidation
within the gas industry in general and New England in particular accelerated.
Electric utility companies were showing increased interest in acquiring gas
utilities due to the perceived advantage of being able to offer customers
multiple energy products and services, utilizing both electricity and natural
gas, in a growing competitive environment. During June and July 1999, Mr. Degen
was contacted on various occasions by executives of other utilities regarding
our interest in pursuing a business combination.

     On July 29, 1999, a special meeting of the Development Committee of the
board of directors was held. After an update regarding business combination
activities in the industry and a discussion of the significant premiums being
paid by acquirors for medium and small-sized distribution companies, the
Committee discussed the strategic alternatives available to us in light of the
recent consolidations in the New England utility industry. Our attorneys made a
presentation with respect to the legal obligations and fiduciary obligations of
the board regarding the consideration of a business combination or sale of the
company. After an extended question and answer period, a Special Committee of
the board consisting of Messrs. Farnum, Alperin and Guthrie was appointed to
review these strategic alternatives and to engage a financial advisor to assist
them. PaineWebber Incorporated was engaged on August 23, 1999 to provide
financial advisory services.

     At a meeting in September 1999, Mr. Thomas Karam of PG Energy indicated
Southern Union's interest in a merger with us.

     At a meeting on September 9, 1999, PaineWebber made a presentation to our
board of directors discussing the business combination activities in the market,
potential parties to business combinations with us and the potential
consequences to our stockholders of a sale or merger of our company. In this
presentation, PaineWebber also gave a description of the transaction process and
the typical time frame involved. At this meeting, our board of directors
authorized management and PaineWebber to prepare a confidential information
memorandum describing our business which could be distributed to a limited
number of companies for the purpose of gauging their interest in pursuing a
business combination transaction.

                                       11
<PAGE>   16

     In October 1999, members of our senior management and representatives of
PaineWebber had conversations with a company operating a large electric and gas
utility system in the mid-Atlantic region of the United States about a possible
business combination transaction. Although a confidentiality agreement was
signed and information was exchanged, none of these conversations led to any
substantive negotiations.

     At a meeting of the board of directors on October 29, 1999, PaineWebber
made a presentation updating the board on the progress made regarding the
preparation of the confidential information memorandum, recent business
combination activities in the market and continued discussion about companies
with a potential interest in a combination with us. Additionally, PaineWebber
discussed various forms of consideration that could be expected and approaches
to valuation of consideration other than cash. After an extended question and
answer period, the board authorized management and PaineWebber to distribute the
confidential information memorandum concerning our company to a representative
number of potentially interested parties for the purpose of gauging their
interest in pursuing a business combination with us.

     Beginning on November 1, 1999, PaineWebber and our management commenced
contacting the numerous potential financial and strategic partners, including
those companies with whom we had previously engaged in discussions.
Confidentiality agreements (including stand-still arrangements) were negotiated
with each participant and upon receipt of a signed confidentiality agreement,
copies of the confidential information memorandum were mailed to the
participants. Representatives of PaineWebber also provided a letter to those
entities who received a confidential information memorandum, advising them that
we reserved our rights to terminate or revise the process and requesting that
all preliminary indications of interest be submitted in writing by November 22,
1999 to enable us to select a group of qualified parties to conduct more
detailed due diligence. Since certain confidentiality agreements took longer
than expected to negotiate and the occurrence of the Thanksgiving holiday,
representatives of PaineWebber sent a second letter on November 15, 1999
indicating that the date for submittal of preliminary indications of interest
was extended to December 1, 1999.

     During this time period, consolidation of the New England natural gas
distribution market accelerated. On November 4, 1999, Keyspan Energy announced
the acquisition of Eastern Enterprises. On November 10, 1999, Energy East
announced the acquisition of Berkshire Energy Resources. Finally, on November
15, 1999, Southern Union announced the acquisition of our neighboring utility,
Providence Energy. Southern Union had previously announced in October 1999 the
acquisition of Fall River Gas, another neighboring utility.

     On November 15, 1999, Mr. Thomas Karam, President and Chief Executive
Officer of PG Energy (a division of Southern Union) and acting as a
representative of Southern Union, contacted representatives of PaineWebber to
discuss a possible business combination with us. On November 18, 1999, Messrs.
Karam, Degen and Peter Kelley, President of Southern Union, met to discuss
trends in the utility industry, strategic issues in the context of a possible
business combination between the two companies and the procedures for the
commencement of due diligence investigations and the exchange of financial
information. Following these discussions Mr. Degen indicated that he would be
willing to discuss with our board of directors a transaction in which we would
become an operating division of Southern Union on terms and conditions that
would generally be comparable to the terms and conditions of the Providence
Energy-Southern Union transaction and that would provide our stockholders with a
premium over book value for their shares comparable to that received by
stockholders of other local gas distribution companies in recent transactions.
Messrs. Karam and Kelley indicated that they would be willing to discuss such a
transaction with Southern Union's board of directors. Following this meeting,
PaineWebber had several discussions with Mr. Karam about the general terms and
conditions on which we would be willing to enter into a business combination
with Southern Union.

     Between November 17 and November 30, 1999, members of our senior management
and Southern Union's and their financial and legal advisors held discussions
pertaining to the terms of a proposed business combination and general business
issues, and conducted due diligence investigations. The discussions on the terms
of a transaction related to the amount and composition of the merger
consideration, a proposed corporate structure and management structure and
roles, including the terms of Mr. Degen's employment following the merger.
Working groups composed of employees of both companies and their financial and
legal advisers were formed to examine and address issues relating to regulatory
requirements, strategic opportunities, the impact of the transaction upon the
communities we serve and the identification of possible operational

                                       12
<PAGE>   17

benefits. On November 27, 1999, a draft of the merger agreement was delivered to
the members of our board of directors.

     A special meeting of our board of directors was held on November 30, 1999.
Members of senior management and our financial and legal advisors also attended
this meeting. Mr. Degen updated the board on the proposed Southern Union
business combination, including potential strategic benefits and potential risks
of the transaction, and the related employment agreement with Mr. Degen. Mr.
Degen and our legal advisors described the terms of the merger agreement and
related documents and informed the board that Southern Union had offered $25 per
share in cash with no further due diligence contingencies. PaineWebber
representatives presented a general overview of the financial aspects of the
transaction, including a review of the methodology by which they conducted their
fairness review. Legal counsel provided advice regarding the board's legal
responsibilities and fiduciary duties in considering the proposed transaction.

     After these presentations and an extended question and answer period,
PaineWebber delivered its fairness opinion to the board to the effect that, as
of that date, the proposed consideration to be received in connection with the
proposed merger was fair from a financial point of view to our stockholders.
After considering and discussing the various presentations at that meeting and
at prior meetings, as well as the recommendation of our senior management, our
board approved, by unanimous vote, the merger with Southern Union and authorized
the execution of the merger agreement. Due to his proposed employment agreement
with Southern Union, Mr. Degen abstained from voting on the merger agreement.

     Following the meeting, we and Southern Union executed the merger agreement
on November 30, 1999 and publicly announced the merger on the morning of
December 1, 1999.

REASONS FOR THE MERGER; RECOMMENDATION OF OUR BOARD OF DIRECTORS

     At a meeting held on November 30, 1999, after determining that the merger
is fair to and in the best interests of our stockholders, our board of directors
unanimously approved the merger agreement. In approving the merger agreement and
in reaching its recommendation, our board of directors consulted with and relied
upon information and reports prepared or presented by our management and our
legal and financial advisors. The following are the material factors that our
board of directors considered:

          1.  Our board of directors' review and analysis of our business,
     current and future financial condition, current earnings and earnings
     prospects, as well as the competitive business environment and changing
     regulatory environment facing a relatively small company such as us;

          2.  Historical market prices of our shares;

          3.  A review of the possible alternatives to a sale, including:

        - the prospects of continuing to operate as a small-sized independent
          gas distribution company or attempting to acquire other smaller
          distribution companies in the New England region;

        - the value to stockholders of such alternatives and the timing and
          likelihood of actually achieving additional value from these
          alternatives; and

        - the possibility that our future performance might lead to a share
          price having a lower value than the consideration being offered in the
          merger;

          4.  The per share consideration of $25 to be paid in the merger
     represents a premium of approximately 22% over the closing per share price
     of our shares on November 30, 1999, the last trading day before the
     announcement of the merger, and a premium of approximately 48% over the
     closing per share price for our shares on November 12, 1999, the last
     trading day before the announcement of the acquisition of Providence Energy
     Corporation, which announcement began affecting our share price since we
     were then the last remaining publicly-held New England gas utility company;

          5.  The financial presentation of PaineWebber, including its opinion
     dated November 30, 1999 to our board of directors, as to the fairness of
     the merger consideration from a financial point of view to our
     stockholders, as described below in "Opinion of Our Financial Advisor;"

          6.  The terms of the merger agreement and the right of our board of
     directors under certain circumstances to terminate the merger agreement
     prior to its approval by our stockholders in the exercise of its fiduciary
     duty in connection with receipt by us of a proposal superior to that given
     by Southern Union; and

          7.  The likelihood of consummation of the merger, including an
     assessment of the risks associated with obtaining necessary federal and
     state regulatory approvals on a timely basis.

     In view of the wide variety of factors considered in connection with its
evaluation of the proposed merger, our board of directors did not find it
practical to, and did not, quantify or otherwise attempt to assign relative
weights to the foregoing factors. Our board of directors viewed its position and
recommendation as being based on the totality of the information presented to
and considered by it. While the foregoing discussion of the information and
factors considered by our board of directors is not intended to be
all-inclusive, it does constitute a summary of all material information
considered by our board of directors in determining to recommend approval of the
merger agreement.

OPINION OF OUR FINANCIAL ADVISOR

     THE FULL TEXT OF THE PAINEWEBBER OPINION, DATED NOVEMBER 30, 1999, WHICH
SETS FORTH THE ASSUMPTIONS MADE, PROCEDURES FOLLOWED, MATTERS CONSIDERED AND
LIMITATIONS ON THE REVIEW UNDERTAKEN, IS ATTACHED AS APPENDIX B TO THIS PROXY
STATEMENT. WE URGE YOU TO READ THIS OPINION CAREFULLY AND IN ITS ENTIRETY. THE
SUMMARY OF THE PAINEWEBBER OPINION SET FORTH IN THIS PROXY STATEMENT IS
QUALIFIED IN ITS ENTIRETY BY REFERENCE TO THE FULL TEXT OF THE PAINEWEBBER
OPINION. THE PAINEWEBBER OPINION IS NOT A RECOMMENDATION TO ANY STOCKHOLDER AS
TO HOW TO VOTE ON THE MERGER.

     We retained PaineWebber as our exclusive financial advisor in connection
with the merger. In connection with such engagement, we requested PaineWebber to
render an opinion as to whether or not the merger consideration is fair, from a
financial point of view, to our stockholders.

     In connection with the board of directors' consideration of the merger,
PaineWebber delivered its opinion to the effect that, as of November 30, 1999,
and based on its review and assumptions and subject to the limitations
summarized below, the merger consideration is fair, from a financial point of
view, to our stockholders. The PaineWebber opinion was prepared at the request
and for the information of our board of directors and does not constitute a
recommendation to any of our stockholders as to how to vote on the merger. The
PaineWebber opinion does not address the relative merits of the merger or any
other transactions or business strategies that the board of directors may have
discussed as alternatives to the merger or the decision for the board of
directors to proceed with the merger. We did not place any limitations upon
PaineWebber with respect to the procedures followed or factors considered in
rendering the PaineWebber opinion.

     In arriving at its opinion, PaineWebber, among other things:

     - Reviewed our Annual Reports, Forms 10-K and related financial information
       for the five fiscal years ended August 31, 1999;

     - Reviewed certain information, including financial forecasts, relating to
       our business, earnings, cash flow, assets and prospects, which we
       furnished to PaineWebber;

     - Conducted discussions with members of our senior management concerning
       our businesses and prospects;

     - Reviewed the historical market prices and trading activity for our shares
       and compared them with that of certain publicly traded companies which
       PaineWebber deemed to be relevant;

     - Compared our results of operations with that of certain companies which
       PaineWebber deemed to be relevant;

                                       14
<PAGE>   19

     - Compared the proposed financial terms of the transactions contemplated by
       the merger agreement with the financial terms of certain other mergers
       and acquisitions which PaineWebber deemed to be relevant;

     - Reviewed a draft of the merger agreement dated November 30, 1999; and

     - Reviewed such other financial studies and analyses and performed such
       other investigations and took into account such other matters as
       PaineWebber deemed necessary, including PaineWebber's assessment of
       general economic, market and monetary conditions.

     In preparing the PaineWebber opinion, PaineWebber relied on the accuracy
and completeness of all information supplied or otherwise made available to
PaineWebber by us, and PaineWebber did not assume any responsibility to
independently verify such information. With respect to the financial forecasts
examined by PaineWebber, PaineWebber assumed that they were reasonably prepared
and reflect the best currently available estimates and good faith judgments of
our management as to our future performance. PaineWebber also relied upon
assurances of our management that we are unaware of any facts that would make
the information or financial forecasts provided to PaineWebber incomplete or
misleading. PaineWebber did not make any independent evaluation or appraisal of
our assets or liabilities (contingent or otherwise) nor was PaineWebber
furnished with any such evaluations or appraisals. PaineWebber also assumed,
with our consent, that (i) the merger will be accounted for under the purchase
method of accounting, and (ii) any material liabilities (contingent or
otherwise, known or unknown) are as set forth in our consolidated financial
statements. The PaineWebber opinion does not constitute a recommendation to any
of our stockholders as to how any such stockholder should vote on the merger.
The PaineWebber opinion does not address the relative merits of the merger and
any other transactions or business strategies discussed by our board of
directors as alternatives to the merger or the decision of our board of
directors to proceed with the merger. PaineWebber's opinion was based on
economic, monetary and market conditions existing on the date of its opinion.

     The preparation of a fairness opinion involves various determinations as to
the most appropriate and relevant quantitative methods of financial analyses and
the application of those methods to the particular circumstances. Therefore,
such an opinion is not readily susceptible to partial analysis or summary
description. Accordingly, PaineWebber believes that its analysis must be
considered as a whole and that considering any portion of its analysis and of
the factors considered, without considering all analyses and factors, could
create a misleading or incomplete view of the process underlying the PaineWebber
opinion. In its analyses, PaineWebber made numerous assumptions with respect to
industry performance, general business and economic conditions and other
matters, many of which are beyond our control. Any estimates contained in these
analyses are not necessarily indicative of actual values or predictive of future
results or values, which may be significantly more or less favorable than as set
forth in these analyses. In addition, analyses relating to the value of
businesses do not purport to be appraisals or to reflect the prices at which
businesses may be sold. Accordingly, these estimates are inherently subject to
substantial uncertainty and neither we nor PaineWebber assume responsibility for
the accuracy of these estimates.

     The following paragraphs summarize the significant analyses performed by
PaineWebber in arriving at its opinion.

     Historical Stock Performance.  PaineWebber reviewed the history of trading
prices for our shares, both separately and in relation to comparable companies.
The comparable companies were selected based on several criteria, including
relative size, profitability, total revenue, growth characteristics, business
position and credit rating. The comparable companies are indicated in the
following paragraph.

     Selected Comparable Public Company Analysis.  Using publicly available
information, PaineWebber compared our selected historical financial, operating
and stock market performance data to the corresponding data of certain publicly
traded companies that PaineWebber deemed relevant. The comparable companies
consisted of:

<TABLE>
<S>                                             <C>
     NUI Corporation                            South Jersey Industries
     Energy South                               Delta Natural Gas Company
     New Jersey Resources                       SEMCO Energy
</TABLE>

                                       15

     With respect to us and our comparable companies, PaineWebber calculated
multiples of total enterprise value (market value, as hereinafter defined, plus
preferred stock and debt less cash and cash equivalents) to latest twelve months
("LTM") earnings before interest, taxes, depreciation and amortization
("EBITDA") and LTM earnings before interest and taxes ("EBIT"). PaineWebber also
calculated multiples of market value (share price multiplied by shares
outstanding including in-the-money options and warrants) to LTM net income, LTM
cash flow from operations ("CFFO") and book value of common equity. The
comparable companies analysis resulted in the following ranges of multiples as
of November 26, 1999:

     PaineWebber reviewed the consideration paid or market value (for stock
deals, based on acquirer stock price on the day prior to the announcement of the
transaction) in the comparable transactions and calculated multiples of total
enterprise value to the target's LTM (latest twelve months prior to the
announcement of the transaction) EBITDA, LTM EBIT, and total customers.
PaineWebber also calculated multiples of the consideration paid to the target's
LTM net income, LTM CFFO, and book value of common equity. The comparable
transactions analysis resulted in the following ranges:

     Discounted Cash Flow Analysis.  PaineWebber analyzed us based on an
unleveraged discounted cash flow analysis of our projected financial
performance. This projected financial performance was based upon a five-year
forecast provided by our management. The discounted cash flow analysis
determined the discounted present value of the unleveraged after-tax cash flows
generated over the five-year period and then added a terminal value based upon a
range of EBITDA multiples of 9.0x to 11.0x and EBIT multiples of 13.0x to 15.0x.
The unleveraged after-tax cash flows and terminal value were discounted using a
range of discount rates that represented an estimate of our weighted average
cost of capital.

     Premiums Paid Analysis.  PaineWebber analyzed purchase price per share
premiums paid in 10 publicly disclosed domestic transactions, in nonfinancial
industries, with transaction values between $75 million and $250 million,
announced since January 1, 1997. This analysis indicated the following mean and
median premiums to the target's closing stock price one day, one week and four
weeks prior to the announcement of the transaction:

     We selected PaineWebber to be our financial advisor in connection with the
merger because PaineWebber is a prominent investment banking and financial
advisory firm with experience in the public utility industry and in the
valuation of businesses and their securities in connection with mergers and
acquisitions, negotiated underwritings, secondary distributions of securities,
private placements and valuations for corporate purposes.

     Pursuant to our engagement letter with PaineWebber dated August 23, 1999,
PaineWebber has earned a retention fee of $50,000 and a fee of $400,000 for the
rendering of the PaineWebber opinion. In addition, PaineWebber will receive a
fee of approximately $1,275,000, payable upon the completion of the merger, and
will be reimbursed for certain of its related expenses. PaineWebber will not be
entitled to any additional fees or compensation in the event the merger is not
approved or otherwise completed. We also agreed, under separate agreement, to
indemnify PaineWebber, its affiliates and each of its directors, officers,
agents and employees and each person, if any, controlling PaineWebber or any of
its affiliates against certain liabilities, including liabilities under federal
securities laws.

     In the past, PaineWebber and its affiliates have provided various financial
services to us and have received fees for rendering these services. PaineWebber
may provide financial advisory services to, and may act as

                                       17
<PAGE>   22

underwriter or placement agent for, the combined company in the future. In the
ordinary course of PaineWebber's business, PaineWebber may actively trade
securities of Valley Resources and Southern Union for its own account and for
the accounts of its customers and, accordingly, may at any time hold long or
short positions in such securities.

POTENTIAL CONFLICTS AND INTERESTS OF CERTAIN PERSONS IN THE MERGER

     In considering the recommendation of our board with respect to the merger,
you should be aware that members of our management and board of directors have
the following interests in the merger that may be different from, or in addition
to, your interests generally and represent conflicts of interest. Our board of
directors was aware of these interests and considered them in approving the
merger agreement.

     Employment Agreement.  In connection with the merger agreement, Southern
Union entered into a three-year employment agreement with Alfred P. Degen, which
will become effective upon the completion of the merger. The employment
agreement provides Mr. Degen's base salary will be set by the president of
Southern Union but will not be less than $200,000, which was his base salary on
November 30, 1999, the day he signed the employment agreement. He also will have
the opportunity to earn an annual incentive bonus which must be equal to at
least 37.5% of his base salary. Mr. Degen will receive a $1,000,000 bonus
payable at the effective time of the merger. If Mr. Degen's employment is
terminated without "cause" or if Mr. Degen terminates his employment for "good
reason" (as such terms are defined in the employment agreement), Mr. Degen will
receive:

     - a severance payment equal to three times his base salary plus the amount
       of his incentive compensation paid for the most recently completed fiscal
       year;

     - continued health, life and disability benefits for three years; and

     - payment for the actuarial equivalent of the excess of the retirement
       pension which would have accrued, determined as if he had accumulated 36
       additional months of service credit, over the retirement pension which
       had accrued.

     If any of the payments made to Mr. Degen would be subject to the excise tax
imposed under the Internal Revenue Code, Southern Union will pay Mr. Degen an
amount equal to such excise tax and any related interest and penalties.

     Change in Control Agreements.  We have severance agreements containing
change in control provisions with Alfred P. Degen, Charles K. Meunier, Richard
G. Drolet, Jeffrey P. Polucha and Sharon Partridge. These agreements were
entered into before we began to explore the possibility of selling our company.

     These agreements provide that, if during the 24 months following a change
of control the officer is terminated without cause or terminates his or her own
employment as a result of adverse actions by us or our successors, the officer
will receive a lump sum severance amount and continuation of certain welfare
plan benefits. The agreements also provide that if the officer terminates his or
her employment for any reason during the 15 months following the later of a
change of control or the expiration of the six month period after any person
publicly announces an intention to take actions which would constitute a change
of control (which was deemed to occur on December 1, 1999 when we announced the
signing of the merger agreement), the officer will receive a lump sum severance
amount and continuation of certain welfare plan benefits. In either case, the
lump sum severance payment is an amount equal to:

     - an amount equal to the officer's unpaid base salary plus amounts due
       under any compensation plan;

     - three times covered compensation (defined as the annual salary at date of
       change of control plus the cash portion of Valley Resources Executive
       Incentive Compensation Plan) for the year in which the change of control
       occurs for Mr. Degen and two times covered compensation for the other
       named officers; and

     - a lump sum cash payment for the actuarial equivalent of the excess of the
       retirement pension which would have accrued after the termination date
       for those additional months for which severance is paid to the officer
       and the retirement pension which had accrued.

                                       18
<PAGE>   23

     In addition, if we terminate an executive during the 15 months following a
change of control, or during the six months after any person publicly announces
an intention to take actions which would constitute a change in control, we will
also provide the officer with the same life insurance, disability,
hospitalization and medical plans which were in effect immediately before our
change of control until the earlier of three years after the change in control
for Mr. Degen and two years for the other named officers or when the executive
has obtained new employment and is covered by equivalent benefits.

     Mr. Degen has agreed to forego the benefits of his change of control
agreement and entered into an employment agreement with Southern Union.

     Deferred Compensation Plan.  Our Directors Deferred Compensation Plan
permits outside directors to defer director's fees to a date between the
director's 65th birthday and one month after the director's 70th birthday. Upon
a change of control, this plan provides that each director may elect to receive
a lump sum payment of all deferred compensation plus interest, to receive
benefits as originally elected under the plan, or to receive installments
commencing upon the change of control.

     Director Retirement Plan.  Our Director Retirement Plan provides retirement
benefits to members of our board who are not our employees or employees of any
subsidiary.

     Defense, Indemnification and Insurance for Officers and Directors.  For a
period of six years after the effective time, Southern Union has agreed to
indemnify our present and former officers and directors and the present and
former officers and directors of our subsidiaries for any losses resulting from
the acts or omissions occurring before the effective time to the extent provided
under our restated articles of incorporation and bylaws in effect on November
30, 1999. If any claims are asserted 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,
Southern Union will use its reasonable best efforts to provide officers' and
directors' liability insurance for acts or omissions occurring before the
effective time covering each person currently covered by our officers' and
directors' liability insurance policy on terms equal in coverage and amount to
those of such policy in effect on November 30, 1999. In satisfying this
obligation, if the annual premiums of such insurance coverage are more than 200%
higher than 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 Officers and Directors."

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

     Each stockholder who receives cash in the merger will recognize any gain or
loss realized in the transaction. Generally, the gain or loss realized will be
measured by the difference between the purchase price of the shares and the
adjusted basis of the shares in the hands of the holder. Such gain or loss would
be capital gain or loss provided that the shares were held as a capital asset on
the effective date of the merger, and would be long-term capital gain or loss if
such shares were held for more than one year.

     We will not recognize any gain or loss as a result of the merger. The
merger will be treated as a purchase of our stock by Southern Union and we will
retain our historic tax basis in our assets and our other tax attributes,
assuming that Southern Union does not make an election under Section 338(g) of
the Internal Revenue Code.

     The discussion set forth above of the material federal income tax
consequences of the merger is included for general information only. It does not
address the state, local or foreign tax aspects of the merger. In addition, it
does not discuss the federal income tax considerations that may be relevant to
certain persons, including holders of options or warrants, and may not apply to
certain holders subject to special tax rules, including dealers in securities,
foreign holders and holders who acquired their shares of our stock pursuant to
the exercise of options or otherwise as compensation. The discussion is based
upon currently existing provisions of the Internal Revenue Code, existing
Treasury regulations thereunder and current administrative rulings and court
decisions. All of the foregoing is subject to change and any such change could
affect the continuing validity of this discussion.

     Each stockholder should consult his or her own tax advisor with respect to
the specific tax consequences of the merger to him or her, including the
application and effect of state, local and foreign tax laws.

REGULATORY MATTERS

     The following is a summary of the material regulatory requirements
affecting the merger. While there can be no guarantee if and when we will obtain
any of the consents or approvals required for the mergers or what conditions
they may contain, and even though Southern Union has not filed for all its
required approvals from all of the agencies discussed, we currently believe that
the necessary approvals can be obtained.

     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 Florida Public Service Commission ("FPSC"), the
Pennsylvania Public Utility Commission ("PPUC"), the Railroad Commission of
Texas ("RRC") and various municipalities in Texas where Southern Union conducts
business. The MPSC and the PPUC must approve the mergers. Southern Union must
also receive approval from the FPSC and the PPUC for certain financing
arrangements for the mergers, namely securities issued and long-term debt
assumed by Southern Union in connection with the mergers. No RRC or municipality
approvals are required.

     The utility operations of our subsidiaries are subject to the regulatory
jurisdiction of the Rhode Island Public Utility Commission ("RIPUC"). The Rhode
Island Division of Public Utilities and Carriers ("DPU") must also approve the
mergers.

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

     Antitrust Considerations.  Under the Hart-Scott-Rodino Antitrust
Improvements Act of 1976 and the rules of the Federal Trade Commission (the
"FTC"), the mergers may not be consummated until notifications have been given
and certain information has been furnished to the FTC and the U.S. Department of
Justice Antitrust Division and specified waiting period requirements have been
satisfied. The expiration or earlier termination of the Hart-Scott-Rodino Act's
waiting period does not preclude the Department of Justice or the FTC from
challenging the mergers on antitrust grounds either before or after consummation
of the mergers. Private parties and state attorneys general may also bring legal
action under federal or state antitrust laws under certain circumstances. We and
Southern Union filed notification and report forms under the Hart-Scott-Rodino
Act with the FTC and the Antitrust Division on March 1, 2000. On March 31, 2000,
the Federal Trade Commission requested additional information in connection with
its analysis of the merger under this Act.

     General.  Southern Union and our utility subsidiaries possess rights and
franchises, and environmental permits and licenses. Some of these may need to be
transferred, renewed or replaced as a result of the mergers. Neither we nor
Southern Union anticipate any difficulties at the present time in making or
obtaining such transfers, renewals or replacements.

     Under the merger agreement, we have agreed to use our 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 we and Southern Union believe that we will receive
the requisite regulatory approvals for the mergers or related financings, we
cannot determine when we will receive such approvals. It is a condition to the
consummation of the mergers (subject to waiver) that final non-appealable orders
approving the mergers or related financings 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 merger will be accounted for under the purchase method of accounting
under generally accepted accounting principles.

NO RIGHTS OF DISSENTING STOCKHOLDERS

     Rhode Island law does not provide for dissenters' rights to stockholders of
a publicly-traded company.

                              THE MERGER AGREEMENT

     The following description of the merger agreement highlights certain
important terms of the merger agreement. We have attached a copy of the merger
agreement as Appendix A to this proxy statement. The summary of the merger
agreement we provide below is qualified in its entirety by reference to that
agreement. We encourage you to read the merger agreement because it is the legal
document that governs the merger.

STRUCTURE OF THE MERGER

     Under the merger agreement, SUG Acquisition Corporation, a wholly-owned
subsidiary of Southern Union, will merge into us. After the subsidiary mergers
described below, we will be merged into Southern Union. Southern Union will
continue as the surviving corporation and we will be a division of Southern
Union. Our non-utility subsidiaries will become subsidiaries of Southern Union.

CLOSING; EFFECTIVE TIME

     We will close the merger at 10:00 a.m., Eastern time, within five business
days after satisfaction or waiver of the conditions set forth in the merger
agreement, unless we agree on a later date. This date is referred to as the
"closing date." On the closing date, we will file articles of merger and a plan
of merger with the Secretary of State of the State of Rhode Island under Rhode
Island law and a certificate of merger with the Secretary of State of the State
of Delaware under Delaware law. The merger will become effective upon filing of
these documents. This moment is referred to as the "effective time."

SUBSIDIARY MERGERS

     Immediately after the effective time, Valley Gas, our wholly-owned
subsidiary, will merge into us. Immediately after the consummation of the Valley
Gas merger, Bristol and Warren Gas will merge into us. Immediately after the
consummation of the Bristol and Warren Gas merger, we will merge into Southern
Union.

MERGER CONSIDERATION

     In the merger, each share of our common stock that you own will be
converted into the right to receive $25.00 in cash.

EXCHANGE OF OUR STOCK CERTIFICATES FOR MERGER CONSIDERATION

     BankBoston N.A., c/o EquiServe, L.P., will act as exchange and paying agent
in connection with the merger. At the effective time, Southern Union will
deposit in trust with the exchange and paying agent an amount of cash
representing the merger consideration. The exchange and paying agent will invest
the merger consideration in United States government-backed obligations or in
the highest quality commercial paper. As soon as practical after the effective
time, the exchange and paying agent will mail to you a letter of transmittal and
instructions regarding the surrender of your stock certificates for
cancellation. After receiving your certificates together with the letter of
transmittal, duly executed, the exchange and paying agent will send you the cash
you will be entitled to receive.

     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. In addition, 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 and paying agent with a lost certificate affidavit. In addition,
you must give the exchange and paying agent a bond in an amount as the exchange
and paying agent may ordinarily require and you must indemnify Southern Union
against any claim that may be made against Southern Union because of the
certificate claimed to have been lost, stolen or destroyed.

                                       21
<PAGE>   26

     Twelve months after the effective time, the exchange and paying agent will
deliver to Southern Union any funds that remain undistributed. From that point
forward, Southern Union will act as exchange and paying agent. If you have not
surrendered your certificates to the exchange and paying agent by then, you will
only be entitled to look to Southern Union as a general creditor for payment of
the merger consideration.

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

     You should not send in your stock certificates until you receive a
transmittal letter.

COVENANTS AND OTHER AGREEMENTS

     Interim Operations.  We have agreed that, except as provided by the merger
agreement or as consented to by Southern Union, from the date of the merger
agreement until the effective time, we and our subsidiaries will:

     - not make or permit any material change in the general nature of our
       business;

     - maintain our ordinary course of business under prudent business judgment
       and consistent with past practice and policy;

     - preserve our ongoing business and use reasonable efforts to maintain our
       goodwill;

     - not enter into any material transaction or contract other than in the
       ordinary course of business;

     - not hire any new employee unless the employee is a bona fide replacement
       for a presently-filled position;

     - not file any material applications, petitions, motions, orders, briefs,
       settlements or agreements in any material proceeding or related appeal
       before a government body without, to the extent reasonably practicable,
       consulting Southern Union;

     - not make any changes in financial policies or practices, or strategic or
       operating policies or practices, except as required by law, rule or
       regulation;

     - except in the ordinary course of business or under the terms of any of
       our existing contracts, employee benefit plans or collective bargaining
       agreements, not grant any increase or change in total compensation,
       benefits or pay any bonus to any employees;

     - not grant or enter into any contract, written or oral, with respect to
       continued employment for any employee, officer or director;

     - not make any loan or advance to any officer, director, stockholder,
       employee, individual or entity other than in the ordinary course of
       business;

       negotiate, any gas purchase, exchange, storage, supply or transportation
       contract; and

     - not assume any note, debenture or other evidence of indebtedness which by
       its terms does not mature within two years.

     Employees; Benefits.  For our employees (excluding unionized employees) and
those of our subsidiaries, Southern Union has agreed:

     - to provide such employees who continue their service with Southern Union
       during the 24 months immediately following the closing date with benefits
       no less favorable in the aggregate than the benefits that are now
       provided under our benefit plans;

     - to recognize, for purposes of eligibility, vesting and benefit accrual
       under all benefit plans provided to such employees after the effective
       time, the tenure of employment, as recognized by us or any of our
       subsidiaries as of the closing date;

                                       22
<PAGE>   27

     - to permit each such employee to carry forward all days of sick leave
       accrued before the closing date; and

     - to provide retiree medical plan coverage which is collectively equal to
       the benefits provided to them by us currently to any former employee (and
       his or her eligible dependents) during the 60 months immediately
       following the closing date.

     Southern Union has also agreed to assume, at the effective time, all
collective bargaining agreements covering any of our employees and our
subsidiaries, and to discharge when due any and all of our liabilities and the
liabilities of our subsidiaries under the collective bargaining agreements after
the effective time.

     Certain Other Covenants and Agreements.  The merger agreement also contains
additional covenants by us to:

     - not declare or pay or permit any of our subsidiaries to declare or pay
       any dividends or make other distributions of our capital stock or our
       subsidiaries' capital stock, except for regular dividends on our common
       stock that do not exceed the current rate of $0.75 per share per year and
       dividends by our subsidiaries to us;

     - cooperate and cause our subsidiaries to cooperate with Southern Union's
       requests with respect to the refinancing, repurchase, redemption or
       repayment of our indebtedness or any of our subsidiaries' indebtedness
       that may be required or that Southern Union may request before the
       mergers;

     - except as discussed below (see "--No Solicitation" below), recommend to
       our stockholders the approval of the merger agreement;

     - except as discussed below (see "-- No Solicitation"), not initiate or
       encourage any inquiry or proposal about mergers with other parties, sales
       of substantial assets, sales of shares representing a majority or greater
       interest in us or any of our subsidiaries or other business combinations
       or, except in certain instances, negotiate, discuss, approve or recommend
       any such alternative acquisition proposal; and

     - use commercially reasonable best efforts at our expense to obtain all
       necessary consents, approvals and waivers needed in connection with the
       transactions contemplated by the merger agreement.

     The merger agreement also contains certain additional covenants of Southern
Union to:

     - amend our stock plans to provide for the issuance of Southern Union stock
       instead of our common stock; and

     - maintain our charitable contributions of at least $60,000 for at least
       the next two calendar years.

NO SOLICITATION

     The merger agreement provides that we must terminate all existing
discussions or negotiations with third parties, if any, regarding an
"alternative proposal," which we define below. In addition, we may not, nor may
we authorize or permit any of our subsidiaries' 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, an alternative
       proposal; 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 an alternative proposal.

     An "alternative proposal" is:

     - a merger, consolidation or other business combination, share exchange,
       sale of shares of capital stock, tender offer or exchange offer or
       similar transaction involving us or any of our subsidiaries;

     - 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, us or any of our subsidiaries,
       including

                                       23
<PAGE>   28

       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 us or any of our
       subsidiaries; 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 us or any of our subsidiaries.

     Before receiving the approval of the merger by our stockholders, if our
board receives an unsolicited written proposal from a third party relating to an
alternative proposal that our board determines is financially superior to the
merger and will have adequate sources of funding, we may take the following
steps if we first give Southern Union two days written notice and obtain a
confidentiality agreement from the third party which is substantially the same
as our confidentiality agreement with Southern Union:

     - furnish information to, and otherwise engage in substantive discussions
       with the third party that submitted the unsolicited alternative proposal
       if our board determines, in its good faith judgment after consulting with
       its financial advisor and outside counsel, that it is reasonably
       necessary to engage in such discussions in order for the board to comply
       with its fiduciary duties under applicable law; and

     - take and disclose to our stockholders a position regarding an alternative
       proposal, or amend or withdraw such position, pursuant to Rules 14d-9 and
       14e-2 under the Exchange Act, or make such disclosure to our stockholders
       which, in the good faith judgment of our board, is required by applicable
       law, based on the advice of our outside counsel.

     The merger agreement also prohibits our 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,
       an alternative proposal; or

     - causing us 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:

        - our board determines, in its good faith judgment, after consulting
          with our financial advisor and outside counsel, that an unsolicited
          proposal regarding an alternative proposal is financially superior to
          our stockholders than the merger; and

        - our 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 an alternative proposal,
          or cause us to enter into any agreement related to an alternative
          proposal would create a reasonable possibility of a breach of the
          fiduciary duties of our board under applicable law.

     We must promptly notify Southern Union of:

     - the receipt of any alternative proposal;

     - 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.

     We must use all reasonable efforts to keep Southern Union informed of the
status and details of any such inquiry, offer or proposal and provide Southern
Union two days' advance notice before we give non-public information to any such
person or entity. If any such inquiry, offer or proposal is in writing, we
agreed to promptly deliver to Southern Union a copy of such inquiry, offer or
proposal. If we decide to accept such alternative proposal and enter into a
definitive agreement with respect to such proposal, we must give Southern Union
five business days' notice of our intent to enter into a definitive agreement.
In addition, during this five-day period, we must give Southern Union an
opportunity to adjust the terms of the merger agreement so that

                                       24
<PAGE>   29

the parties can proceed with the merger and negotiate in good faith with
Southern Union with respect to any such adjustments. At the same time as we
terminate the merger agreement after accepting an alternative proposal, we must
also pay the required termination fee (see "-- Termination of the Merger
Agreement" and "-- Termination Fees and Expenses -- Termination Fee").

     Before we furnish any non-public information to, enter into negotiations
with, or accept an alternative proposal from a third party, we must give written
notice to Southern Union and obtain an executed confidentiality agreement from
the third party containing substantially the same terms and conditions as our
confidentiality agreement with Southern Union.

CONDITIONS TO THE COMPLETION OF THE MERGER

     Mutual Closing Conditions.  The obligations of Southern Union and us to
complete the merger are subject to the satisfaction or waiver of the following
conditions:

     - accuracy as of the closing date of the representations and warranties
       made by the other party as specified in the merger agreement;

     - performance in all material respects by the other party of its required
       obligations at or before the closing date;

     - obtaining all required governmental authorizations necessary to complete
       the merger without conditions that would be reasonably likely to be
       materially adverse to Southern Union's or our businesses, operations,
       properties, financial condition, or results of operations;

     - no court, administrative agency, governmental body or arbitrator having
       issued an order to restrain, enjoin or otherwise prevent the consummation
       of the merger agreement or the mergers.

     Additional Closing Conditions for Southern Union's Benefit.  Southern
Union's obligation to complete the merger is subject to the following additional
conditions:

     - approval by our stockholders;

     - receipt of third party consents required to consummate the mergers, other
       than any consents which, if not obtained, are not, individually or in the
       aggregate, reasonably likely to result in a material adverse effect on
       the business, operations, properties, financial condition or results of
       our operations and our subsidiaries after the closing;

     - receipt of all consents and approvals required, under the terms of any
       note, bond or indenture to which we or any of our subsidiaries is a
       party; and

     - the resignation or retirement of each of our directors and the directors
       of our subsidiaries effective as of the closing date.

INDEMNIFICATION AND INSURANCE FOR OFFICERS AND DIRECTORS

     For six years after the completion of the merger, Southern Union will
indemnify our present and former officers and directors and those of our
subsidiaries for acts or omissions which occurred before the effective time. In
addition, for six years after the effective time, Southern Union will use its
reasonable best efforts to provide officers' and directors' liability insurance
for acts or omissions occurring before the effective time for each person
covered by our officers' and directors' liability insurance policy effective on
the date of the merger agreement on equivalent terms. However, if the annual
premiums of such insurance coverage are greater than 200% of the previous year's
premiums, Southern Union must obtain a policy with the best coverage available
for a cost not exceeding such amount.

AMENDMENTS

     We and Southern Union may amend any of the terms of the merger agreement if
the amendment is in writing signed by both of us.

                                       25
<PAGE>   30

TERMINATION OF THE MERGER AGREEMENT

     The merger agreement may be terminated at any time before the closing:

     - by mutual written consent of Southern Union and us;

     - by either Southern Union or us:

             (1) if our stockholders have not approved the merger by February
        28, 2001; or

             (2) at any time after 5:00 p.m., Eastern Time on February 28, 2001,
        if the closing of the merger has not occurred and the party seeking to
        terminate is not in material breach of its representations, warranties,
        covenants or agreements contained in the merger agreement. This date
        will be extended to May 31, 2001, even though all other conditions to
        the closing of the merger have been fulfilled or are capable of being
        fulfilled if:

           - all required approvals, consents, opinions or rulings of all
             government agencies have not been obtained by final order that does
             not contain conditions that are likely to have a material adverse
             effect on the business, operations, properties, financial condition
             or results of operations of the combined company or us, in the case
             of a termination by Southern Union;

           - the applicable waiting period under the Hart-Scott-Rodino Act
             relating to the mergers has not expired or been terminated;

           - any required approval or authorization of any federal, state or
             local governmental agency has not been obtained or become a final
             order;

           - if any state or federal law, order, rule or regulation is adopted
             that prohibits the mergers; or

           - if a court issues a non-appealable order that prohibits the
             consummation of the mergers.

     - By Southern Union:

             (1) if we breach any representation, warranty, covenant or
        agreement which cannot be cured and would make our representations and
        warranties materially inaccurate;

             (2) if our board or any committee of our board:

           - withdraws or modifies, or proposes publicly to withdraw or modify,
             in a manner adverse to Southern Union, its approval or
             recommendation of the merger agreement or the merger;

           - approves or recommends, or proposes publicly to approve or
             recommend, an alternative proposal;

           - causes us to enter into a definitive agreement related to any
             alternative proposal;

           - resolves to take any of the foregoing actions; or

           - if a third party, including a group, acquires securities
             representing greater than 50% of the voting power of our
             outstanding voting securities.

     - By us:

        - if Southern Union breaches any representation, warranty, covenant or
          agreement, which breach cannot be cured and would make Southern
          Union's representations and warranties materially inaccurate, if

           - we give Southern Union at least five business days' notice of our
             intent to enter into a definitive agreement regarding an
             alternative proposal. During this five-day period, we 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 regarding any such
             adjustments;

           - we have paid the required termination fees; and

           - we have entered into a definitive agreement with respect to an
             alternative proposal.

     If the merger agreement is validly terminated, no provision of the merger
agreement will survive (except for the provisions relating to expenses,
termination fees and miscellaneous provisions of general application) and
neither we nor Southern Union shall have liability unless such party negligently
or willfully breaches any provision of the merger agreement.

                                       26

TERMINATION FEES AND EXPENSES

     Payment of the Merger Expenses Generally.  We and Southern Union will pay
all costs and expenses of our performance of and compliance with the merger
agreement except as follows:

     - we will 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 by Southern Union to collect the termination fee
       payable to Southern Union under the merger agreement, plus interest on
       the amount of any portion of the unpaid termination fee. Southern Union
       may calculate this interest 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; and

     - we will pay all fees and expenses of our counsel.

     Termination Fee.  We have agreed to pay Southern Union $5 million in cash
if:

     - we provide Southern Union at least five business days' notice of our
       intent to terminate the merger agreement and have entered into a
       definitive agreement relating to an alternative proposal;

     - Southern Union terminates the merger agreement because our board or any
       committee of our board has:

        - withdrawn or modified, or proposed publicly to withdraw or modify, in
          a manner adverse to Southern Union, its approval or recommendation of

paying agent (the "Paying Agent"), to mail to each holder of record as of the
Effective Time of a certificate or certificates representing the shares of
Company Common

                                        2

Stock ("Company Certificates") that have been converted pursuant to Section
2.1(c): (i) a letter of transmittal (which shall specify that delivery shall be
effected, and risk of loss and title to the Company Certificates shall pass,
only upon actual delivery of the Company Certificates to the Paying Agent and
shall be in such form and have such other provisions as Parent may reasonably
specify) and (ii) instructions for effecting the surrender of the Company
Certificates and receiving the Merger Consideration to which such holder shall
be entitled therefor pursuant to Section 2.1. Upon surrender of a Company
Certificate for cancellation to the Paying Agent or to such other agent or
agents as may be appointed by Parent, together with a duly executed letter of
transmittal and such other documents as the Paying Agent may require, the holder
of such Company Certificate shall be entitled to receive in exchange therefor
the Merger Consideration to which such holder is entitled in accordance with
Section 2.1(c), and the Company Certificate so surrendered shall forthwith be
canceled. If payment of the Merger Consideration is to be made to any person
other than the person in whose name the surrendered Company Certificate is
registered, it shall be a condition of payment that the Company 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 (as defined in Section 4.8) required by reason of the
payment of the Merger Consideration to a person other than the registered holder
of the Company Certificate surrendered or shall have established to the
satisfaction of Parent that such Tax either has been paid or is not applicable.
Until surrendered as contemplated by this Section 2.2, each Company Certificate
(other than a certificate representing shares of Company Common Stock to be
canceled in accordance with Section 2.1(b)) shall be deemed at any time after
the Effective Time to represent only the right to receive upon such surrender
the Merger Consideration contemplated by Section 2.1. No interest will be paid
or will accrue on any cash payable to holders of Company Certificates pursuant
to the provisions of this Article II.

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

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

     (e) Closing of Transfer Books.  After the Effective Time, the stock
transfer books of the Company shall be closed and there shall be no transfers on
the stock transfer books of the Surviving Corporation of shares of Company
Common Stock that were outstanding immediately prior to the Effective Time. If,
after the Effective Time, Company Certificates are presented to Parent, they
shall be canceled and exchanged for the appropriate amount of Merger
Consideration as provided in Section 2.1 and in this Section 2.2.

     (f) Termination of Exchange Agent.  All funds held by the Exchange Agent
for payment to the holders of unsurrendered Company Certificates and unclaimed
at the end of one year from the Effective Time shall be returned to Parent,
after which time any holder of unsurrendered Company Certificates shall look as
a general creditor only to Parent for payment of such funds to which such holder
may be due, subject to applicable law.

                                        3
<PAGE>   41

     (g) Escheat.  Neither the Surviving Corporation nor Parent shall be liable
to any holder of Company Common Stock for Merger Consideration delivered to a
public official pursuant to any applicable abandoned property, escheat or
similar law. Any amounts remaining unclaimed by holders of any such shares of
Company Common Stock five years after the Effective Time (or such earlier date
immediately prior to the time at which such amounts would otherwise escheat to
or become property of any Governmental Authority (as defined in Section 4.4(c))
shall, to the extent permitted by applicable law, become the property of Parent,
free and clear of any claims or interest of any such holders or their
successors, assigns or personal representatives previously entitled thereto.

                                  ARTICLE III

                                  THE CLOSING

     Section 3.1  Closing.  The closing of the Merger (the "Closing") shall take
place at the offices of Hughes Hubbard & Reed LLP, New York, New York, at 10:00
a.m., Eastern time, on a date selected by Parent and reasonably satisfactory to
the Company which is no more than five business days following the date on which
the last of the conditions set forth in Article VIII hereof is fulfilled or, if
permissible, waived (other than conditions that by their nature are required to
be performed on the Closing Date, but subject to satisfaction of such
conditions), or at such other time and date and place as the Company and Parent
shall mutually agree (the "Closing Date").

                                   ARTICLE IV

                 REPRESENTATIONS AND WARRANTIES OF THE COMPANY

     The Company represents and warrants to Parent as follows:

     Section 4.1  Organization And Qualification.  The Company and each of its
Subsidiaries (as defined below) is a corporation duly organized, validly
existing and in good standing under the laws of its jurisdiction of
incorporation or organization, has all requisite corporate power and authority,
and has been duly authorized by all necessary approvals and orders of the Rhode
Island and all other regulatory authorities, in each such case, to own, lease
and operate its assets and properties to the extent owned, leased and operated
and to carry on its business as it is now being conducted and is duly qualified
and in good standing to do business in each jurisdiction in which the nature of
its business or the ownership or leasing of its assets and properties makes such
qualification necessary, other than in such jurisdictions where the failure to
be so qualified and in good standing will not, when taken together with all
other such failures, have a material adverse effect (i) on the business,
properties, financial condition or results of operations of the Company and its
Subsidiaries taken as a whole or (ii) on the ability of the Company and its
Subsidiaries to consummate the Mergers in accordance with this Agreement and the
Related Documents (as defined in Section 4.4(a)) (any such material adverse
effect being hereafter referred to as a "Company Material Adverse Effect"). As
used in this Agreement, the term "Subsidiary" of a person shall mean any
corporation or other entity (including partnerships and other business
associations) of which a majority of the outstanding capital stock or other
voting securities having the power under ordinary circumstances to elect
directors or similar members of the governing body of such corporation or entity
(or otherwise having the power to direct the business and policies of that other
corporation or other entity) shall at the time be held, directly or indirectly,
by such person.

     Section 4.2  Subsidiaries.  Section 4.2(i) of the Company Disclosure
Schedule (as defined in Section 7.6) sets forth a description of all
Subsidiaries and Joint Ventures (as defined below) of the Company and its
Subsidiaries, including the name of each such entity, the state or jurisdiction
of its incorporation or organization, the Company's or its Subsidiary's interest
therein and a brief description of the principal line or lines of business
conducted by each such entity. Except as set forth in Section 4.2(ii) of the
Company Disclosure Schedule, none of the Company's Subsidiaries is a "public
utility company," a "holding company," a "subsidiary company" or an "affiliate"
of any "public utility company" or of any "holding company" within the meaning
of Section 2(a)(5), 2(a)(7), 2(a)(8) or 2(a)(11) of the Public Utility Holding
Company Act of 1935, as amended (the "1935 Act"). Except as set forth in Section
4.2(i) of the Company Disclosure Schedule, all of the issued and outstanding
shares of capital stock owned, directly or indirectly, by the

                                        4

agreement, obligating the Company or any Subsidiary of the Company to issue,
deliver or sell, or cause to be issued, delivered or sold, additional shares of
its capital stock or obligating it to grant, extend or enter into any such

a person shall mean any corporation or other entity (including partnerships and
other business associations) that is not a Subsidiary of such person, in which
such person or one or more of its Subsidiaries owns an equity interest, other
than equity interests held for passive investment purposes which are less than
2% of any class of the outstanding voting securities or equity of any such
entity.

consists of (i) 20,000,000 shares of Company Common Stock and (ii) 500,000
shares of preferred stock, $100 par value (the "Company Preferred Stock"). As of
the close of business on November 29, 1999, there were issued and outstanding
4,991,264 shares of Company Common Stock. No shares of Company Preferred Stock
are issued or outstanding. There are no shares of Company Common Stock or
Company Preferred Stock reserved for issuance upon exercise of outstanding
Company stock options or stock appreciation rights. All of the issued and
outstanding shares of the capital stock of the Company are validly issued, fully
paid, nonassessable and free of preemptive rights. Except as set forth in
Section 4.3 of the Company Disclosure Schedule, there are no outstanding
subscriptions, options, stock appreciation rights, calls, contracts, voting
trusts, proxies or other commitments, understandings, restrictions,
arrangements, rights or warrants, including any right of conversion or exchange
under any outstanding security, instrument or other agreement, obligating the
Company or any Subsidiary of the Company to issue, deliver or sell, or cause to
be issued, delivered or sold, additional shares of the capital stock of the
Company or any Subsidiary of the Company, or obligating the Company or any of
its Subsidiaries to grant, extend or enter into any such agreement or
commitment.

     Section 4.4  Authority; Non-contravention; Statutory Approvals; Compliance.

     (a) Authority.  The Company and each applicable Subsidiary of the Company
has all requisite corporate power and authority to enter into this Agreement and
the Related Documents and, subject to obtaining the Company Shareholders'

thereto, constitutes or will constitute, as the case may be, the valid and
binding obligations of the Company or its applicable Subsidiary, as the case may
be, enforceable against it in accordance with its terms, except to the extent
that enforceability may be limited by applicable bankruptcy, insolvency or other
laws affecting the enforcement of creditors' rights generally and subject to the
general principles of equity (regardless of whether enforcement is sought in a
court of law or equity). As used in this Agreement, the term (i) "Related
Documents" shall mean any Contract provided for in this Agreement to be entered
into by one or more of the parties hereto or their respective Subsidiaries in
connection with the Mergers, and (ii) "Contract" shall mean any agreement,
contract, document, instrument, obligation, promise, commitment or undertaking

the Related Documents by the Company and its Subsidiaries do not, and the

required by, or result in a right of termination, cancellation, or acceleration
of any obligation or the loss of a benefit under, or result in the creation of
any Lien upon any of the properties or assets of the Company or any of its
Subsidiaries or any of its Joint Ventures (any such violation, conflict, breach,
default, right of termination, modification, cancellation or acceleration, loss
or creation, a "Violation" with respect to the Company, its Subsidiaries and
Joint Ventures) pursuant to any provisions of (i) the articles of incorporation,
by-laws or similar governing documents of the Company, subject to Section
4.4(b)(i) of the Company Disclosure Schedule, any of its Subsidiaries or any of
its Joint Ventures, (ii) subject to obtaining the Company Required Statutory
Approvals and the receipt of the Company Shareholders' Approval, any statute,
law, ordinance, rule, regulation, judgment, decree, order, injunction, writ,
permit or license of any Governmental Authority applicable to the Company, any
of its Subsidiaries or any of its Joint Ventures, or any of their respective
properties or assets or (iii) subject to obtaining the third-party consents or
other approvals set forth in Section 4.4(b)(iii) of the Company Disclosure
Schedule (the "Company Required Consents"), any note, bond, mortgage, indenture,
deed of trust, license, franchise, permit, concession, contract, lease,
commitment, security agreement, loan agreement, or other instrument, obligation,
agreement or other Contract of any kind to which the Company, any of its
Subsidiaries or any of its Joint Ventures is a party or by which any of such
persons or any of their properties or assets may be bound or affected, excluding
from the foregoing clauses (ii) and (iii) such Violations as would not have,
individually or in the aggregate, a Company Material Adverse Effect.

     (c) Statutory Approvals.  Except as described in Section 4.4(c) of the
Company Disclosure Schedule (the "Company Required Statutory Approvals"), no
declaration, filing or registration with, or notice to or authorization, consent
or approval of, any court, federal, state, local or foreign governmental or
regulatory body (including a stock exchange or other self-regulatory body) or
authority (each, a "Governmental Authority") is necessary for the execution and
delivery of this Agreement and the Related Documents by the Company and its
Subsidiaries or Joint Ventures or the consummation by the Company and its
Subsidiaries or Joint Ventures of the transactions contemplated hereby and
thereby, the failure to obtain, make or give which are, individually or in the
aggregate, reasonably likely to have a Company Material Adverse Effect, it being
understood that references in this Agreement to "obtaining" such Company
Required Statutory Approvals shall mean making such declarations, filings or
registrations, giving such notices, obtaining such authorizations, consents or
approvals and having such waiting periods expire as are necessary to avoid a
violation of law.

     (d) Compliance; Contracts.  Except as set forth in Section 4.10 of the
Company Disclosure Schedule, or as disclosed in the Company SEC Reports (as
defined in Section 4.5) delivered to Parent prior to the date of this Agreement,
neither the Company nor any of its Subsidiaries nor any of its Joint Ventures is
in violation of, is under investigation with respect to any violation of, or has
been given notice of, or been charged with any violation of, or failure to
comply with, any law, statute, order, rule, regulation, tariff, franchise
agreement, principle of common law, ordinance or judgment (including, without
limitation, any applicable Environmental Law, as defined in Section 4.10(i)(ii))
of any Governmental Authority except for violations that, individually and in
the aggregate, do not have a Company Material Adverse Effect. The Company and
its Subsidiaries and Joint Ventures have all permits, licenses, franchises and
other governmental authorizations, consents and approvals necessary to conduct
their respective businesses and to own, operate and vote all of their respective
assets as currently conducted in all respects, except those which the failure to
obtain would not, individually or in the aggregate, have a Company Material
Adverse Effect. Neither the Company nor any of its Subsidiaries nor any of its
Joint Ventures nor to the Knowledge (as defined below) of any of the foregoing,
any other party thereto, is in breach or violation of or in default in the
performance or observance of any term or provision of, and no event has occurred
or is occurring which, with lapse of time or action by a third party, could
result in a default by any party thereto under, (i) its articles of
incorporation or by-laws or similar governing document or (ii) any commitment,
deed of trust, franchise, permit, concession, security agreement, obligation,
agreement, indenture, mortgage, loan agreement, note, lease, bond, or other
Contract, license, approval or other instrument to which it is a party or by
which it is bound or to which any of its property is subject, except for
breaches, violations or defaults that, individually and in the aggregate, do not
have a Company Material Adverse Effect. Set forth in Section 4.4(d) of the
Company Disclosure Schedule is a list as the date hereof of all Contracts to
which any of the Company or any of its Subsidiaries is a party involving a total
commitment by or to any party thereto of more than $125,000 on an annual basis
or more than $500,000 on its remaining term which cannot be terminated on no
more than sixty (60) days' notice without penalty or additional cost to

                                        6
<PAGE>   44

the Company or its applicable Subsidiary as the terminating party. Except as
disclosed in the Company SEC Reports delivered to Parent prior to the date of
this Agreement, and with such exceptions as are not, individually or in the
aggregate, reasonably likely to have a Company Material Adverse Effect, each
Contract to which the Company or any of its Subsidiaries is a party is in full
force and effect and constitutes the valid and binding obligation of the parties
thereto, enforceable against such party in accordance with its terms, except to
the extent that enforceability may be limited by applicable bankruptcy,
insolvency or other laws affecting the enforcement of creditors' rights
generally and subject to the general principles of equity (regardless of whether
enforcement is sought in a court of law or equity). For purposes of this
Agreement, (i) an individual will be deemed to have "Knowledge" of a particular
fact or other matter if such individual is actually aware of such fact or other
matter and (ii) a person (other than an individual) will be deemed to have
"Knowledge" of a particular fact or other matter if any individual who is
serving as a director or officer of such person or any Subsidiary of it has
actual knowledge after reasonable inquiry of such fact or other matter.

     (e) Except as set forth in Section 4.4(e) of the Company Disclosure
Schedule, there is no "non-competition" or other similar Contract that restricts
the ability of the Company or any of its Affiliates to conduct business in any
geographic area or that would reasonably be likely to restrict Parent or any of
its Affiliates to conduct business in any geographic area. As used in this
Agreement, the term "Affiliate" shall mean, with respect to any person, any
other person that directly, or through one or more intermediaries, controls or
is controlled by or is under common control with such first person. As used in
this definition, "control" (including with correlative meanings, "controlled by"
and "under common control with") shall mean possession, directly or indirectly,
or power to direct or cause the direction of management or policies (whether
through ownership of securities or partnership or other ownership interests, by
contract or otherwise).

     Section 4.5  Reports and Financial Statements.  The filings required to be
made by the Company and its Subsidiaries and Joint Ventures since January 1,
1996 under the Securities Act of 1933, as amended (the "Securities Act"), the
Securities Exchange Act of 1934, as amended (the "Exchange Act"), the 1935 Act
and applicable state public utility laws and regulations have been filed with
the Securities and Exchange Commission (the "SEC") or the appropriate state
public utilities commission, as the case may be, including all forms,
statements, financial statements, reports, agreements (oral or written) and all
documents, exhibits, schedules, amendments and supplements appertaining thereto,
were duly made and complied (or, with respect to such documents to be filed
after the date of this Agreement, will be duly made and will comply), as of
their respective dates, in all material respects with all applicable
requirements of the appropriate statute and the rules and regulations
thereunder. The Company has made available to Parent a true and complete copy of
each report, schedule, registration statement and definitive proxy statement
filed by the Company with the SEC since January 1, 1997 (as such documents,
including those filed after the date of this Agreement, have since the time of
their filing been amended, the "Company SEC Reports"). As of their respective
dates, the Company SEC Reports did (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 the Company included in
the Company SEC Reports (collectively, the "Company Financial Statements") have
been (or will be) prepared in accordance with U.S. generally accepted accounting
principles applied on a consistent basis ("GAAP") (except as may be indicated
therein or in the notes thereto and except with respect to unaudited statements
as permitted by Form 10-Q of the SEC) and fairly present (or will fairly
present) the consolidated financial position of the Company and its Subsidiaries
as of the dates thereof and the consolidated results of operations and cash
flows for the periods then ended. True, accurate and complete copies of the
articles of incorporation and by-laws of the Company, each of its Subsidiaries
and each of its Joint Ventures have been made available to Parent. The Company
SEC Reports delivered to Parent prior to the date of this Agreement accurately
disclose all material regulation of the Company and each of its Subsidiaries and
Joint Ventures that relates to the utility business of any of the Company and
each of its Subsidiaries and Joint Ventures.

     Section 4.6  Absence of Certain Changes or Events.  Except as disclosed in
the Company SEC Reports delivered to Parent prior to the date of this Agreement,
from August 31, 1999, the Company and each of its Subsidiaries have conducted
their businesses only in the ordinary course of business consistent with past

                                        7
<PAGE>   45

practice, and there has not been, and no fact or condition exists which,
individually or in the aggregate, would have or, insofar as reasonably can be
foreseen, could have, a Company Material Adverse Effect.

     Section 4.7  Litigation.  Except as disclosed in the Company SEC Reports
delivered to Parent prior to the date of this Agreement or as set forth in
Section 4.8(g) or Section 4.10 of the Company Disclosure Schedule, (a) there are
no claims, suits, actions or proceedings pending or, to the Knowledge of the
Company and its Subsidiaries, threatened, nor are there any investigations,
requests for information, or reviews pending or, to the Knowledge of the Company
and its Subsidiaries, threatened against, relating to or affecting the Company
or any of its Subsidiaries, and (b) there are no judgments, decrees,
injunctions, rules or orders of any court, governmental department, commission,
agency, instrumentality or authority or any arbitrator applicable to the Company
or any of its Subsidiaries, except for any of the foregoing under clauses (a)
and (b) that, individually and in the aggregate, would not reasonably be
expected to have a Company Material Adverse Effect. There is no claim, suit,
action or proceeding pending that challenges, or that may have the effect of
preventing, delaying, making illegal, or otherwise interfering with, the Mergers
or any of the transactions contemplated hereby.

     Section 4.8  Tax Matters.  "Taxes," as used in this Agreement, means any
federal, state, county, local or foreign taxes, charges, fees, levies or other
assessments, including, without limitation, all net income, gross income, sales

personal property, gross receipts, capital stock, production, business and
occupation, disability, employment, payroll, license, estimated, stamp, custom

additions to any such taxes. "Tax Return," as used in this Agreement, means a

governmental entity with respect to Taxes.

          (a) Filing of Timely Tax Returns.  Except as set forth in Section

     such Tax Returns were and are in all material respects true, complete and
     correct.

          (b) Payment of Taxes.  Except as set forth in Section 4.8(a) of the

     contested in good faith and for which adequate reserves have been taken.

          (c) Tax Reserves.  All material Taxes payable by the Company and its
     Subsidiaries for all taxable periods and portions thereof through the date
     of the most recent financial statements contained in the Company Financial
     Statements delivered to Parent prior to the date of this Agreement are
     properly reflected in such financial statements in accordance with GAAP,
     and the unpaid Taxes of the Company and its Subsidiaries do not exceed the
     amount shown therefor on such financial statements, adjusted for the Taxes
     incurred in the ordinary course of business through the Effective Time.

          (d) Extensions of Time for Filing Tax Returns.  Except as set forth in
     Section 4.8(d) of the Company Disclosure Schedule, neither the Company nor
     any of its Subsidiaries have requested any extension of time within which
     to file any material Tax Return, which Tax Return has not since been filed.

          (e) Waivers of Statute of Limitations.  Neither the Company nor any of
     its Subsidiaries has executed any outstanding waivers or comparable
     consents regarding the application of the statute of limitations with
     respect to any Taxes or Tax Returns.

          (f) Expiration of Statute of Limitations.  The statute of limitations
     for the assessment of all material Taxes has expired for all applicable
     material Tax Returns of the Company and each of its Subsidiaries, or those
     material Tax Returns have been examined by the appropriate taxing
     authorities for all periods through the date hereof, and no deficiency for
     any material Taxes has been proposed, asserted or assessed against the
     Company or any of its Subsidiaries that has not been resolved and paid in
     full.

     its Subsidiaries, threatened, with regard to any Taxes or Tax Returns of
     the Company or any of its Subsidiaries.

          (h) Tax Rulings.  Neither the Company nor any of its Subsidiaries has
     received a Tax Ruling (as defined below) or entered into a Closing
     Agreement (as defined below) with any taxing authority that would have a
     continuing effect after the Closing Date. "Tax Ruling," as used in this
     Agreement, shall mean a written ruling of a taxing authority relating to
     Taxes. "Closing Agreement," as used in this Agreement, shall mean a written

          (iii) An "Employee Benefit Plan" means any employee benefit plan,
     program, policy, practice, agreement or other arrangement providing
     benefits to any current or former employee, officer or director of the
     Company or any of its Subsidiaries or any beneficiary or dependent thereof

     or to which the Company or any of its Subsidiaries contributes or is
     obligated to contribute, whether or not written, including without
     limitation any employee welfare benefit plan within the meaning of Section
     3(l) of ERISA, any employee pension benefit plan within the meaning of
     Section 3(2) of ERISA (whether or not such plan is subject to ERISA) and

     disability, stock purchase, stock option, stock award, phantom stock, stock
     appreciation right, severance, employment, change of control or fringe
     benefit plan, program or agreement.

          (iv) A "Plan" means any Employee Benefit Plan other than a
     Multiemployer Plan.

          (v) A "Multiemployer Plan" means any "multiemployer plan" within the

     a result of a complete or partial withdrawal from such Multiemployer Plan,
     as those terms are defined in Part I of Subtitle E of Title IV of ERISA or

     (b) Section 4.9(b) of the Company Disclosure Schedule includes a complete
list of all Employee Benefit Plans and, with respect to executive welfare
benefit plans and nonqualified pension, savings and deferred compensation plans,
states the number of employees participating in or covered by such plans. Such
list identifies all Plans which are funded with or provide benefits in the form
of Company Common Stock or other securities of the Company or its Subsidiaries.

     (c) With respect to each Plan, the Company has delivered to Parent a true,
correct and complete copy of: (i) each writing constituting a part of such Plan,
including without limitation all plan documents, trust agreements, and insurance
contracts and other funding vehicles, and a description of each unwritten plan;
(ii) the three most recent Annual Reports (Form 5500 Series) and accompanying
schedules, if any; (iii) the current summary plan description and any material
modifications thereto, if required to be furnished under ERISA; (iv) the most

delivered to Parent a true, correct and complete copy of each current employee
handbook relating to employees of the Company or any of its Subsidiaries. Except
as specifically provided in the foregoing documents delivered to Parent, there

     (d) Section 4.9(b) of the Company Disclosure Schedule identifies each Plan
that is intended to be a "qualified plan" within the meaning of Section 401(a)
of the Code ("Qualified Plans"). The IRS has issued a favorable determination
letter with respect to each Qualified Plan and the related trust that has not
been revoked, and, to the Knowledge of the Company and its Subsidiaries, nothing
has occurred since the date of such determination letter which cannot be
remedied by timely amendment and which would adversely affect the qualified
status of such plan. Section 4.9(b) of the Company Disclosure Schedule
identifies each Plan or related trust which is intended to meet the requirements
of Code Section 501(c)(9) (a "VEBA"), and except as disclosed in Section 4.9(d)
of the Company Disclosure Schedule, each such VEBA meets such requirements, has
received a favorable determination letter from the IRS, and provides no
disqualified benefits (as such term is defined in Code Section 4976(b)).

     (e) All contributions required to be made to any Plan by applicable law or
regulation or by any Plan document or other contractual undertaking, and all
premiums due or payable with respect to insurance policies funding any Plan,
have been timely made or paid in full. Each Plan that is an employee welfare
benefit plan under Section 3(l) of ERISA (i) is funded through an insurance
company contract or a contract with a health maintenance organization, (ii) is,
or is funded through, a VEBA identified as such in Section 4.9(b) of the Company
Disclosure Schedule, or (iii) is unfunded.

                                       10

     (f) With respect to each Employee Benefit Plan, the Company and its
Subsidiaries have substantially complied, and are now in substantial compliance,
with all provisions of ERISA, the Code and all laws and regulations applicable
to such Employee Benefit Plans and each Plan has been administered in all
material respects in accordance with its terms and the terms of any applicable
collective bargaining agreement. There is not now, nor do any circumstances now
exist that could reasonably be expected to give rise to, any requirement for the
posting of security with respect to a Plan or the imposition of any Lien on the
assets of the Company or any of its Subsidiaries under ERISA or the Code. To the
Knowledge of the Company and its Subsidiaries, no non-exempt prohibited
transaction (as defined in Section 406 of ERISA or Section 4975 of the Code) or
breach of fiduciary duty has occurred with respect to any Plan, and no event has
occurred which would subject the Company or Parent to any material liability for
any excise tax, tax on unrelated business taxable income, penalty, or fine under
ERISA or the Code.

     (g) With respect to each Plan that is subject to Title IV of ERISA, the
minimum funding requirements of Section 302 of ERISA or Section 412 of the Code,
or Section 4971 of the Code: (i) there does not exist any accumulated funding
deficiency within the meaning of Section 412 of the Code or Section 302 of
ERISA, whether or not waived; (ii) as of August 31, 1999, the fair market value
of the assets of each such Plan that is a defined benefit plan equals or exceeds
the "projected benefit obligation" (within the meaning of Financial Accounting
Standard No. 87) under such Plan, based upon the actuarial assumptions set forth
in the most recent actuarial report for such Plan; (iii) no reportable event
within the meaning of Section 4043(c) of ERISA for which the 30-day notice
requirement has not been waived has occurred since December 31, 1994 in respect
of any such Plan which is a defined benefit Plan; (iv) all premiums to the PBGC
have been timely paid in full; (v) no liability (other than for premiums to the
PBGC not yet due and for the payment of benefits and contributions in the
ordinary course) under Title IV of ERISA has been incurred by the Company or any
of its Subsidiaries; (vi) to the Knowledge of the Company and its Subsidiaries,
the PBGC has not instituted proceedings to terminate any such Plan and no
condition exists that presents a material risk that such proceedings will be
instituted or which would constitute grounds under Section 4042 of ERISA for the
termination of, or the appointment of a trustee to administer, any such Plan;
and (vii) neither the Company nor any of its Subsidiaries has taken any action
to terminate such Plan.

     (h) No Employee Benefit Plan is a Multiemployer Plan or a plan that has two
or more contributing sponsors at least two of which are not under common
control, within the meaning of Section 4063 of ERISA (a "Multiple Employer
Plan"). None of the Company and its Subsidiaries nor any of their respective
ERISA Affiliates has, at any time during the last six years, contributed to or
been obligated to contribute to any Multiemployer Plan or Multiple Employer
Plan. None of the Company and its Subsidiaries nor any of their respective ERISA
Affiliates has incurred any Withdrawal Liability or other liability that has not
been satisfied in full.

     (i) There does not now exist, nor do any circumstances exist that could
reasonably be expected to result in, any Controlled Group Liability to the
Company, any of its Subsidiaries, or Parent with respect to any employee benefit
plan of any ERISA Affiliate of the Company or any its Subsidiaries. Without
limiting the generality of the foregoing, neither the Company nor any of its
Subsidiaries, nor any of their respective ERISA Affiliates, has engaged in any
transaction described in Section 4069 or Section 4204 or 4212(c) of ERISA since
December 31, 1993.

     (j) Except as set forth in Section 4.9(j) of the Company Disclosure
Schedule and except for health continuation coverage as required by Section
4980B of the Code or Part 6 of Title I of ERISA or applicable state law, the
Company and its Subsidiaries have no material liability for life, health,
medical or other welfare benefits to former employees or beneficiaries or
dependents of former employees.

     (k) Neither the execution and delivery of this Agreement nor the
consummation of any of the transactions contemplated hereby will (either alone
or in conjunction with any other event) cause any amount to be payable, cause
the accelerated funding, vesting, exercisability, payment or delivery of, or
increase the amount or value of, any payment or benefit to any current or former
employee, officer or director of the Company or any of its Subsidiaries.

     (l) Section 4.9(l)(i) of the Company Disclosure Schedule sets forth a list
as of no more than thirty (30) days prior to the date of this Agreement, of all
the present officers and employees of the Company and its

                                       11

identifying those who are union employees and those who are part-time employees.
Except as set forth in Section 4.9(l)(ii) of the Company Disclosure Schedule, as
of the date of this Agreement, no labor union or other collective bargaining
unit has been certified or recognized by the Company or any of its Subsidiaries.
The Company has provided to Parent a true, complete and correct copy of each
collective bargaining agreement covering employees of the Company and its
Subsidiaries. No labor organization or group of employees of the Company or any
of its Subsidiaries has made a pending demand for recognition or certification,
and there are no representation or certification proceedings or petitions
seeking a representation proceeding presently pending or, to the Knowledge of
the Company or any of its Subsidiaries, threatened to be brought or filed with
the National Labor Relations Board or any other labor relations tribunal or
authority. There are no organizing activities, strikes, work stoppages,
slowdowns, lockouts, arbitrations or material grievances, or other material
labor disputes pending or, to the Knowledge of the Company or any of its
Subsidiaries, threatened against or involving the Company or any of its
Subsidiaries. Each of the Company and its Subsidiaries is in compliance in all
material respects with all applicable laws and collective bargaining agreements
respecting employment and employment practices, terms and conditions of
employment, wages and hours and occupational safety and health.

     (m) There are no pending or, to the Knowledge of the Company and its
Subsidiaries, threatened claims (other than claims for benefits in the ordinary
course), lawsuits or arbitrations, and, to the Knowledge of the Company and its
Subsidiaries, there is no set of circumstances which may reasonably give rise to
a claim or lawsuit, against the Plans, any fiduciaries thereof with respect to
their duties to the Plans, or the assets of any of the trusts under any of the
Plans which could reasonably be expected to result in a material liability. No
Plan is the subject of any pending, or, to the Knowledge of the Company and its
Subsidiaries, threatened, governmental audit or investigation.

     (n) Except as set forth in Section 4.9(n) of the Company Disclosure
Schedule, the Company and its Subsidiaries, as applicable, have reserved the
right to unilaterally amend and terminate each Plan which is an "employee
welfare benefit plan," as such term is defined in Section 3(1) of ERISA, which

4.10 of the Company Disclosure Schedule or as disclosed in the Company SEC
Reports delivered to Parent prior to the date of this Agreement:

          (a) Compliance.  Except where the failure to be in such compliance
     would not, individually or in the aggregate, have a Company Material
     Adverse Effect, (i) the Company and each of its Subsidiaries are in
     compliance with all applicable Environmental Laws (as defined in Section
     4.10(i)(ii)) and (ii) neither the Company nor any of its Subsidiaries has
     received any communication from any Governmental Authority or any written
     communication from any other person that alleges that the Company or any of
     its Subsidiaries is not in compliance with applicable Environmental Laws.

          (b) Environmental Permits.  The Company and each of its Subsidiaries
     has obtained or has applied for all environmental, health and safety
     permits and governmental authorizations (collectively, the "Environmental
     Permits") necessary for the construction of its facilities or the conduct
     of its operations, and all such Environmental Permits are in good standing
     or, where applicable, a renewal application has been timely filed and is
     pending agency approval, and the Company and its Subsidiaries are in
     compliance with all terms and conditions of the Environmental Permits, and
     the Company reasonably believes that any transfer, renewal or reapplication
     for any Environmental Permit required as a result of the Mergers can be
     accomplished in the ordinary course of business, except where the failure
     to obtain or to be in such compliance would not, individually or in the
     aggregate, have a Company Material Adverse Effect.

        (c) Environmental Claims.  There are no Environmental Claims (as defined
     in Section 4.10(i)(i)) pending or, to the Knowledge of the Company and its
     Subsidiaries, threatened

     (ii) against any real or personal property or operations that the Company

     aggregate, a Company Material Adverse Effect.

          (d) Releases.  Except for Releases of Hazardous Materials the
     aggregate liability for which would not have a Company Material Adverse
     Effect, there have been no Releases (as defined in Section 4.10(i)(iv)) of
     any Hazardous Material (as defined in Section 4.10(i)(iii)) that would be
     reasonably likely to (i) form the basis of any Environmental Claim against
     the Company or any of its Subsidiaries or Joint Ventures, or (ii) to the
     Knowledge of the Company and its Subsidiaries, cause damage or diminution
     of value to any of the operations or real properties owned, leased or

     Joint Ventures.

          (e) Predecessors.  The Company and its Subsidiaries have no Knowledge
     of any Environmental Claim pending or threatened, or of any Release of
     Hazardous Materials that would be reasonably likely to form the basis of
     any Environmental Claim, in each case against any person or entity
     (including, without limitation, any predecessor of the Company or any of
     its Subsidiaries) whose liability the Company or any of its Subsidiaries or
     Joint Ventures retained, succeeded to, acquired, or assumed, either
     contractually or by operation of law, or against any real or personal
     property which the Company or any of its Subsidiaries or Joint Ventures
     formerly owned, leased or managed, in whole or in part, except for Releases
     of Hazardous Materials the liability for which would not have, individually
     or in the aggregate, a Company Material Adverse Effect.

          (f) Listed Sites.  There have been no Hazardous Materials generated by
     the Company or any of its Subsidiaries or Joint Ventures (or predecessors
     of any of them) that have been disposed of or come to rest at any site that

     have been provided to Parent prior to the date of this Agreement.

          (h) Liens.  The real property owned, operated or leased by the Company

premiums has been received by any of the Company and its Subsidiaries with
respect to such policies, and none of the Company and its Subsidiaries 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 Company Material
Adverse Effect. None of the Company and its Subsidiaries 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 Company and its Subsidiaries 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 Company Material Adverse Effect.
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 Company and its Subsidiaries, except for such non-payments of premiums,
cancellations, renewals or disallowances which are not, individually or in the
aggregate, reasonably likely to have a Company Material Adverse Effect.

     Section 4.20  Regulatory Proceedings.  Except as disclosed in the Company
SEC Reports delivered to Parent prior to the date of this Agreement, other than
purchase gas adjustment provisions, none of the Company or its Subsidiaries all
or part of whose rates or services are regulated by a Governmental Authority (a)
has rates that have been or are being collected subject to refund, pending final
resolution of any rate proceeding pending before a Governmental Authority or on
appeal to the courts, or (b) is a party to any rate proceedings before a
Governmental Authority that are, individually or in the aggregate, reasonably
likely to result in any orders having a Company Material Adverse Effect.

     Section 4.21  The Company Rights Agreement.  Prior to the date of this
Agreement, the Company has delivered to Parent a true and complete copy of the
Company Rights Agreement. The consummation of the transactions contemplated by
this Agreement will not result in the triggering of any right or entitlement of
the holders of the Company Common Stock or other Company securities under the
Company Rights Agreement. Neither the Company nor any of its Subsidiaries is a
party to any agreement similar to the Company Rights Agreement.

                                   ARTICLE V

                    REPRESENTATIONS AND WARRANTIES OF PARENT

     Parent represents and warrants to the Company as follows:

     Section 5.1  Organization and Qualification.  Each of Parent and Merger Sub
is a corporation duly organized, validly existing and in good standing under the
laws of its jurisdiction of incorporation, has all requisite corporate power and
authority, and Parent has been duly authorized by all necessary approvals and
orders of the Florida, Missouri, Pennsylvania and Texas regulatory authorities
and the Federal Energy Regulatory Commission (the "FERC"), to own, lease and
operate its assets and properties to the extent owned, leased and operated and
to carry on its business as it is now being conducted.

     Section 5.2  Authority; Statutory Approvals.

     (a) Authority.  Each of Parent and Merger Sub has all requisite corporate
power and authority to enter into this Agreement and, subject to the applicable
Parent Required Statutory Approvals (as defined in Section 5.2(b)), to
consummate the transactions contemplated hereby. The execution and delivery of
this

                                       15
<PAGE>   53

Agreement, and the consummation by Parent and Merger Sub of the transactions
contemplated hereby have been duly authorized by all necessary corporate action
on the part of Parent and Merger Sub. This Agreement has been duly and validly
executed and delivered by Parent and Merger Sub and, assuming the due
authorization, execution and delivery by the other signatories hereto,
constitutes a valid and binding obligation of Parent and Merger Sub enforceable
against them in accordance with its terms, except to the extent that
enforceability may be limited by applicable bankruptcy, insolvency or similar
laws affecting the enforcement of creditors' rights generally and subject to the
general principles of equity (regardless of whether enforcement is sought in a
court of law or equity).

     (b) Statutory Approval.  Except as described in Section 5.2(b) of the
Parent Disclosure Schedule (as defined in Section 7.6) (the "Parent Required
Statutory Approvals"), no declaration, filing or registration with, or notice to
or authorization, consent or approval of, any Governmental Authority is
necessary for the execution and delivery of this Agreement by Parent or Merger
Sub or the consummation by Parent or Merger Sub of the transactions contemplated
hereby, the failure to obtain, make or give which would have, individually or in
the aggregate, a material adverse effect on the ability of Parent and Merger Sub
to consummate the Mergers in accordance with this Agreement (any such material
adverse effect being hereafter referred to as a "Parent Material Adverse
Effect"), it being understood that references in this Agreement to "obtaining"
such Parent Required Statutory Approvals shall mean making such declarations,
filings or registrations; giving such notices; obtaining such authorizations,
consents or approvals; and having such waiting periods expire as are necessary
to avoid a violation of law.

                                   ARTICLE VI

     set forth in the Company Financial Statements delivered to Parent prior to
     the date of this Agreement.

          (e) Charter Documents; Other Actions.  The Company shall not, nor
     shall it permit any of its Subsidiaries to, (i) amend or propose to amend
     its respective articles of incorporation, by-laws or regulations, or
     similar organizational documents or (ii) take or fail to take any other
     action, which in any such case would reasonably be expected to prevent or
     materially impede or interfere with the Mergers.

          (f) Acquisitions.  Except as disclosed in Section 6.1(f) of the
     Company Disclosure Schedule, the Company shall not, nor shall it permit any
     of its Subsidiaries to, acquire or agree to acquire, by merging or

     on its remaining term which cannot be terminated on no more than 60 days'
     notice without penalty or cost to the Company or any of its Subsidiaries as

     business efforts to renew any material Contract to which the Company or any
     of its Subsidiaries is a party or waive, release or assign any material
     rights or claims with respect thereto.

          (h) Capital Expenditures.  The Company shall not, nor shall it permit

     for capital expenditures as set forth in Section 6.1(h) of the Company
     Disclosure Schedule.

          (i) No Dispositions.  The Company shall not, nor shall it permit any
     of its Subsidiaries to, sell, lease, license, encumber or otherwise dispose
     of, any of its respective assets, other than encumbrances or dispositions
     in the ordinary course of business consistent with past practice.

          (j) Indebtedness.  The Company shall not, nor shall it permit any of
     its Subsidiaries to, incur or guarantee any indebtedness (including any
     debt borrowed or guaranteed or otherwise assumed including, without
     limitation, the issuance of debt securities or warrants or rights to
     acquire debt) or enter into any "keep well" or other agreement to maintain
     any financial statement condition of another person or enter into any
     arrangement having the economic effect of any of the foregoing other than
     (i) short-term indebtedness in the ordinary course of business consistent

     at the option of the Company or its applicable Subsidiary on no more than
     30 days' notice without any penalty or premium or (ii) arrangements between
     the Company and its wholly-owned Subsidiaries or among its wholly-owned
     Subsidiaries.

          (k) Compensation, Benefits; Employees.  Except as may be required by
     applicable law or under existing Employee Benefit Plans or collective
     bargaining agreements, as may be required to facilitate or obtain a
     determination letter from the IRS that a plan is a Qualified Plan, or as
     expressly contemplated by this Agreement, the Company shall not, nor shall
     it permit any of its Subsidiaries to, (i) enter into, adopt or amend or
     increase the amount or accelerate the payment or vesting of any benefit or
     amount payable under any Employee Benefit Plan, or otherwise increase the
     compensation or benefits of any director, officer or other employee of the
     Company or any of its Subsidiaries, except for normal increases in
     compensation and benefits (including incentive compensation) or actions in
     the ordinary course of

                                       17
<PAGE>   55

     business, that are consistent with the Company's past practice of adjusting
     compensation and benefits to reflect the average compensation and benefits
     as determined by general industry or market surveys; provided that prior to
     implementing any such increases on the basis of such surveys the Company
     shall advise Parent of its intention so to increase compensation or
     benefits and of the basis therefor and shall otherwise consult with Parent
     concerning such proposed increases, or (ii) enter into or amend any
     employment, severance or special pay arrangement with respect to the
     termination of employment or other similar contract, agreement or
     arrangement with any director or officer or other employee. This subsection
     (k) is not intended to (A) restrict the Company or its Subsidiaries from
     granting promotions to officers or employees based upon job performance or
     workplace requirements in the ordinary course of business consistent with
     past practice or (B) restrict the Company's ability to make available to
     employees the plans, benefits and arrangements that have customarily and
     consistent with past practices been available to officers and employees in
     the context of such merit-based promotion. The Company and its Subsidiaries
     shall not hire any new employee unless such employee is a bona fide
     replacement for a presently-filled position with the Company or a
     Subsidiary as of the date hereof.

          (l) 1935 Act.  The Company shall not, nor shall it permit any of its
     Subsidiaries to, engage in any activities which would cause a change in its
     status, or that of its Subsidiaries, under the 1935 Act.

          (m) Accounting.  The Company shall not, nor shall it permit any of its
     Subsidiaries to, make any changes in their accounting methods, principles
     and practices, except as required by law, rule, regulation or GAAP.

          (n) Cooperation, Notification.  The Company shall, and shall cause its
     Subsidiaries to, (i) confer on a regular and frequent basis with one or
     more representatives of Parent to discuss, subject to applicable law,
     material operational matters and the general status of its ongoing
     operations, (ii) promptly notify Parent of any significant changes in its
     business, properties, assets, condition (financial or other), results of
     operations or prospects, (iii) advise Parent of any change or event which
     has had or, insofar as reasonably can be foreseen, is reasonably likely to
     result in a Company Material Adverse Effect, and (iv) without limiting the
     Company's and its Subsidiaries' obligations under Section 6.1(u)(i),
     promptly provide Parent with copies of all filings made by the Company or
     any of its Subsidiaries with any state or federal court, administrative
     agency, commission or other Governmental Authority in connection with this
     Agreement and the transactions contemplated hereby.

          (o) Third-Party Consents.  The Company shall, and shall cause its
     Subsidiaries to, use all commercially reasonable efforts to obtain all the
     Company Required Consents and other consents required to consummate the
     transactions contemplated hereby. The Company shall promptly notify Parent
     of any failure or prospective failure to obtain any such consents and, if
     requested by Parent, shall provide copies of all the Company Required
     Consents obtained by the Company to Parent.

          (p) Discharge of Liabilities.  The Company shall not, nor shall it
     permit any of its Subsidiaries to, pay, discharge or satisfy any material
     claims, liabilities or obligations (absolute, accrued, asserted or
     unasserted, contingent or otherwise), other than the payment, discharge or
     satisfaction, in the ordinary course of business consistent with past
     practice (which includes the payment of final and unappealable judgments)
     or in accordance with their terms, of liabilities reflected or reserved
     against in, or contemplated by, the most recent consolidated financial
     statements (or the notes thereto) of the Company included in the Company
     SEC Reports delivered to Parent prior to the date of this Agreement, or
     incurred in the ordinary course of business consistent with past practice.

          (q) Insurance.  The Company shall, and shall cause its Subsidiaries
     to, maintain with financially responsible insurance companies insurance in
     such amounts and against such risks and losses as are customary for
     companies engaged in the electric and gas utility industry.

          (r) Permits.  The Company shall, and shall cause its Subsidiaries to,
     use reasonable efforts to maintain in effect all existing governmental
     permits pursuant to which the Company or any of its Subsidiaries operate.

          (s) No Rights Triggered.  The Company shall ensure that the entering
     into of this Agreement and the Related Documents and the consummation of
     the transactions contemplated hereby and thereby and

                                       18
<PAGE>   56

     any other action or combination of actions, or any other transactions
     contemplated hereby and thereby, do not and will not result, directly or
     indirectly, in the grant of any rights to any person under any Contract
     (other than the employment agreements disclosed in Section 6.1(s) of the
     Company Disclosure Schedule) to which it or any of its Subsidiaries is a
     party or otherwise. In addition, the Company shall not amend or waive any
     rights in a manner that would adversely affect any party's ability to
     consummate the Mergers or the economic benefits of the Mergers to Parent.

          (t) Taxes.  The Company shall not, and shall cause its Subsidiaries
     not to, (i) make or rescind any express or deemed material election
     relating to Taxes, (ii) settle or compromise any material claim, audit,
     dispute, controversy, examination, investigation or other proceeding
     relating to Taxes, (iii) materially change any of its methods of reporting
     income or deductions for federal income Tax purposes, except as may be
     required by applicable law, or (iv) file any material Tax Return other than
     in a manner consistent with past custom and practice.

          (u) The Company and its Subsidiaries shall:

             (i) Not file any material application, petition, motion, order,
        brief, settlement or agreement in any material proceeding before any
        Governmental Authority which involves the Company or any of its
        Subsidiaries, and appeals related thereto without, to the extent
        reasonably practicable, consulting Parent; provided, however, that if
        such proceeding is reasonably likely to have a Company Material Adverse
        Effect, the Company shall not make any such filing without the consent
        of Parent, which consent shall not be unreasonably withheld or delayed;

             (ii) Not engage in or modify, except in the ordinary course of
        business, any material intercompany transactions involving any other
        Subsidiary of the Company;

             (iii) Not make any changes in financial policies or practices, or
        strategic or operating policies or practices;

             (iv) Not make any loan or advance to any officer, director,
        shareholder, employee or any other person other than advances for
        business purposes to employees in the ordinary course of business;

             (v) Not purchase, sell, lease, dispose of or otherwise transfer or
        make any Contract for the purchase, sale, lease, disposition or transfer
        of, or subject to Lien, any of the assets of the Company or its
        Subsidiaries other than in the ordinary course of business; and

             (vi) Not terminate any existing gas purchase, exchange or
        transportation contract necessary to supply firm gas at all city gate
        delivery points or enter into any new contract for the supply,
        transportation, storage or exchange of gas with respect to the Company's
        or its Subsidiaries' regulated gas distribution operations or renew or
        extend or negotiate any existing contract providing for the same where
        such contract is not terminable within sixty (60) days without penalty
        without obtaining Parent's prior written consent; provided, however,
        that if the Company provides Parent with a copy of any such proposed new
        Contract, Parent shall be deemed to have consented to the entering into
        of such Contract if Parent does not notify the Company of its
        disapproval of such Contract by the end of the second business day after
        receipt by Parent of such copy of such proposed new Contract.

          (v) Customer Notifications.  At any time and from time to time as
     reasonably requested by Parent prior to the Closing Date, each of the
     Company and its Subsidiaries will permit Parent at Parent's expense to
     insert preprinted single-page customer education materials into billing
     documentation to be delivered to customers affected by this Agreement;
     provided, however, that the Company has reviewed in advance and consented
     to the content of such materials, which consent shall not be unreasonably
     withheld or delayed. Other means of notifying customers may be employed by
     either the Company or Parent, at the expense of the initiating party, but
     in no event shall any notification be initiated without the prior consent
     of the other party (which consent shall not be unreasonably withheld or
     delayed).

          (w) Company Bondholders' Consent.  The Company shall use its
     reasonable best efforts to obtain consents from all holders of each series
     of First Mortgage Bonds issued under the Indenture of First Mortgage dated
     as of December 15, 1992 between Valley, the Company, as Guarantor, and
     State Street

                                       19
<PAGE>   57

     Bank and Trust Company, as Trustee, and from all holders of each series of
     debentures issued under the Indenture between the Company and Mellon Bank,
     N.A., dated as of September 1, 1997, each as amended or supplemented from
     time to time, to such amendments to such Indentures as requested by Parent.

          (x) Financing Activities.  The Company shall, and shall cause its
     Subsidiaries to, cooperate, to the fullest extent commercially reasonable
     and practicable, with Parent's requests with respect to refinancing by the
     Company and its Subsidiaries of the current maturities of any of their
     indebtedness, and any repurchase, redemption or prepayment by the Company
     or any of its Subsidiaries of any of their indebtedness that may be
     required prior to or because of the Mergers or that Parent may request that
     the Company or any of its Subsidiaries effect prior to the Mergers, so as
     to permit Parent 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 Company's or its Subsidiaries' indebtedness as
     in effect on the date of this Agreement, any of the Company's or its
     Subsidiaries' indebtedness outstanding on the Closing Date; provided,
     however, that neither the Company nor any of its Subsidiaries shall be
     required to consummate prior to the Effective Time any such refinancing,
     repurchase, redemption or repayment requested by Parent.

          (y) Legislative Action.  The Company shall, and shall cause its
     Subsidiaries to, use commercially reasonable efforts to cause the Rhode
     Island Legislature to: (i) unconditionally amend the legislative charter of
     Valley to expressly and unconditionally approve and authorize the Valley
     Merger, (ii) unconditionally amend the legislative charter of Bristol to
     expressly and unconditionally approve and authorize the Bristol Merger,
     (iii) expressly and unconditionally approve and authorize the Company
     Merger, and (iv) expressly and unconditionally permit Parent to qualify to
     do business in Rhode Island in accordance with the RIBCA, notwithstanding
     contrary provisions of sec.7-1.1-3 and sec.7-1.1-99 (collectively, the
     "Legislative Actions"). All Legislative Actions shall be in form and
     substance reasonably acceptable to Parent. The Company shall, and shall
     cause its Subsidiaries to, cooperate with Parent to effect the Legislative
     Actions as soon as practicable after the date of this Agreement.

     Section 6.2  Covenant of the Company; Alternative Proposals.  (a) From and
after the date hereof, the Company agrees (i) that it will not, its Subsidiaries
will not, and it will not authorize or permit any of its or its Subsidiaries'
officers, directors, employees, agents and representatives (including, without
limitation, any investment banker, financial advisor, attorney or accountant
retained by it or any of its Subsidiaries or any of the foregoing) to, directly
or indirectly, encourage, initiate or solicit (including by way of furnishing
information) or take any other action designed or which could be reasonably
expected to facilitate any inquiries or the making of any proposal or offer
(including, without limitation, any proposal or offer to its shareholders) which
constitutes or may reasonably be expected to lead to an Alternative Proposal (as
defined below) from any person or engage in any discussion or negotiations
concerning, or provide any non-public information or data to make or implement
or otherwise in any way cooperate or facilitate the making of an Alternative
Proposal; (ii) that it will immediately cease and cause to be terminated any
existing solicitation, initiation, encouragement, activity, discussions or
negotiations with any parties conducted heretofore with a view of formulating an
Alternative Proposal; and (iii) that it will notify Parent orally and in writing
of any such inquiry, offer or proposals, within one business day of the receipt
thereof, and that it shall keep Parent informed of the status of any such
inquiry, offer or proposal; provided, however, that notwithstanding any other
provision hereof, the Company may (1) at any time prior to the time at which the
Company Shareholders' Approval shall have been obtained, engage in discussions
or negotiations with a third party who (without solicitation in violation of the
terms of this Agreement) seeks to initiate such discussions or negotiations and
may furnish such third party information concerning the Company and its
business, properties and assets if, and only to the extent that, (A) (x) the
third party has first made an Alternative Proposal that, in the good faith
judgment of the Company's Board of Directors (after consulting with its
financial and legal advisors) is financially superior to the Company's
shareholders than the Merger and has demonstrated that it will have adequate
sources of financing to consummate such Alternative Proposal, and (y) the Board
of Directors of the Company shall conclude in good faith, based upon the advice
of outside counsel and such other matters as the Board of Directors of the
Company deems relevant, that such actions are necessary for the Company's Board
of Directors to act in a manner consistent with its fiduciary duties to
shareholders under applicable law, and

                                       20
<PAGE>   58

(B) prior to furnishing such information to, or entering into discussions or
negotiations with, such person or entity, the Company (x) provides at least two
business days' prior written notice to Parent to the effect that it intends to
furnish information to, or intends to enter into discussions or negotiations
with, such person or entity, and of the identity of the person or group making
the Alternative Proposal and the material terms thereof, including a copy of any
offer or proposal submitted in writing, and (y) receives from such person an
executed confidentiality agreement containing the same terms and conditions as
the Confidentiality Agreement (as defined in Section 7.1) except that such
confidentiality agreement shall not prohibit such person from making an
unsolicited Alternative Proposal, and (2) comply with Rule 14e-2 promulgated
under the Exchange Act with regard to a tender or exchange offer. "Alternative
Proposal" shall mean any merger, acquisition, consolidation, reorganization,
business combination, share exchange, tender offer, exchange offer or similar
transaction involving the Company or any of the Company's Subsidiaries, or any
proposal or offer to acquire in any manner, directly or indirectly, a material
equity interest in or a material portion of the assets of the Company or any of
the Company's Subsidiaries, including any single or multi-step transaction or
series of related transactions.

     (b) Neither the Board of Directors of the Company nor any committee thereof
may, (i) withdraw or modify, or propose publicly to withdraw or modify, in a
manner adverse to Parent, the approval or recommendation by the Board of
Directors of the Company or such committee of the Merger or this Agreement, (ii)
approve or recommend or propose publicly to approve or recommend an Alternative
Proposal or (iii) cause the Company or any of its Subsidiaries to enter into any
letter of intent, agreement in principle, acquisition agreement or other similar
agreement related to any Alternative Proposal. Notwithstanding the foregoing,
prior to the time at which the Company Shareholders' Approval has been obtained,
in response to an Alternative Proposal (without solicitation in violation of the
terms of this Agreement) from a third party, if the Board of Directors of the
Company determines, in its good faith judgment, after consultation with and the
receipt of the advice of its financial advisor and outside counsel, that such
proposal is financially superior to the Company's shareholders than the Merger
and that failure to do any of the actions set forth in clauses (i), (ii) or
(iii) above of this Section 6.2(b) would create a reasonable possibility of a
breach of the fiduciary duties of the Company's Board of Directors under
applicable law, the Board of Directors of the Company may (i) withdraw or modify
its approval or recommendation of the Merger or this Agreement, approve or
recommend an Alternative Proposal or cause the Company to enter into an
Alternative Proposal and (ii) negotiate with a third party with respect to such
Alternative Proposal, and subject to the Company having paid to Parent the fees
described in Section 9.3 hereof and having entered into a definitive agreement
with respect to such Alternative Proposal, terminate this Agreement; provided,
however, that prior to entering into a definitive agreement with respect to an
Alternative Proposal, the Company shall give Parent at least five (5) days'
notice thereof, and shall cause its representatives to negotiate with Parent to
make such adjustments in the terms and conditions of this Agreement as would
enable the Company to proceed with the transactions contemplated herein on such
adjusted terms; provided, further, that if the Company and Parent are unable to
reach an agreement on such adjustments within five (5) days after such notice
from the Company, the Company may enter into such definitive agreement, subject
to the provisions of Article IX.

     Section 6.3  Employment Agreement.  Parent and Mr. Alfred P. Degen have
entered into an employment agreement in the form attached hereto as Exhibit A
(the "Employment Agreement"), which will become effective upon consummation of
the Merger.

                                  ARTICLE VII

                             ADDITIONAL AGREEMENTS

     Section 7.1  Access to Information.

     (a) Upon reasonable notice and during normal business hours, the Company
shall, and shall cause its Subsidiaries to, afford to the officers, directors,
employees, accountants, counsel, investment bankers, financial advisors and
other representatives of Parent reasonable access, throughout the period prior
to the Effective Time, to all of its and its Subsidiaries' properties, books,
contracts, commitments and records (including, but not limited to, Tax Returns)
and during such period, the Company shall, and shall cause its Subsidiaries to,
furnish promptly to Parent access to each report, schedule and other document
filed or received by it or any of

                                       21
<PAGE>   59

its Subsidiaries pursuant to the requirements of federal or state securities
laws or filed with or sent to the SEC, the Department of Justice, the Federal
Trade Commission or any other federal or state regulatory agency or commission.
Each party shall, and shall cause its Subsidiaries to, afford to the officers,
directors, employees, accountants, counsel, investment bankers and other
representatives of the other reasonable access to all information concerning
themselves, their subsidiaries, directors, officers and shareholders and such
other matters as may be reasonably requested by the other party in connection
with any filings, applications or approvals required or contemplated by this
Agreement. Each party shall, and shall cause its Subsidiaries and
representatives to, hold in strict confidence all Information (as defined in the
Confidentiality Agreement) concerning the other parties furnished to it in
connection with the transactions contemplated by this Agreement in accordance
with Confidentiality Agreement dated November 1, 1999 between the Company and
Parent, as it may be amended from time to time (the "Confidentiality
Agreement").

     (b) As promptly as practicable after Parent's request, the Company will
furnish such financial and operating data and other information pertaining to
the Company or its Subsidiaries and their businesses and assets as Parent may
reasonably request; provided, however, that nothing herein will obligate the
Company or any of its Subsidiaries 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 Company or its Subsidiary is a party or to
which any of its assets is subject in providing such information, or to incur
any costs with respect to Parent's external auditors (or the Company's or its
Subsidiaries' external auditors in the event a report by such auditors is
requested by Parent) providing accounting services with respect to issuing an
auditor's report required by or for Parent.

     Section 7.2  Proxy Statement.

     (a) (i) As soon as practicable after the date hereof, the Company shall
take such reasonable steps as are necessary for the prompt preparation and
filing with the SEC of a proxy statement relating to the Company Special Meeting
(as defined in Section 7.4(a)) (together with any amendments thereto or
supplements thereto, the "Proxy Statement"). Each of Parent and the Company
shall furnish all information concerning it, its officers and directors, and the
holders of its capital stock as the other may reasonably request in connection
with the preparation and filing of the Proxy Statement. The Company will use all
commercially reasonable efforts to cause the Proxy Statement to be cleared by
the SEC as promptly as practicable after filing and as promptly as practicable
after such clearance, the Company shall mail the Proxy Statement to its
shareholders entitled to notice of and to vote at the Company Special Meeting.
As promptly as practical after consultation between Parent and the Company, the
Company shall respond to any comments made by the SEC with respect to the Proxy
Statement.

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

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

                                       22
<PAGE>   60

     (iv) No representation, warranty, covenant or agreement is made by or on
behalf of the Company with respect to information supplied by any other person
other than its Subsidiaries for inclusion in the Proxy Statement. No
representation, warranty, covenant or agreement is made by or on behalf of
Parent with respect to information supplied by any other person for inclusion in
the Proxy Statement. No filing of, or amendment or supplement to, the Proxy
Statement shall be made by the Company without providing Parent with the
opportunity to review and comment thereon; provided, however, that no such
filing, amendment or supplement (i) that relates to Parent or any of its
Subsidiaries or (ii) that is reasonably likely to have a material adverse effect
on Parent or any of its Subsidiaries, shall be made without Parent's prior
written approval. If at any time prior to the Company Special Meeting any
information relating to any party hereto or any of their respective officers,
directors, shareholders or Subsidiaries, should be discovered by any party
hereto which should be set forth in an amendment or supplement to the Proxy
Statement so that the Proxy Statement would not include any untrue statement of
a material fact or omit to state any material fact necessary to make the
statements therein, in light of the circumstances under which they were made,
not misleading, the party which discovers such information shall promptly notify
the other party hereto and an appropriate amendment or supplement describing
such information shall be promptly prepared, filed with the SEC and, to the
extent required by law, disseminated to the shareholders of the Company.

     (b) Letter of the Company's Accountant.  Following receipt by Grant
Thornton LLP, the Company's independent auditor, of an appropriate request from
the Company pursuant to SAS No. 72, the Company shall use its best efforts to
cause to be delivered to Parent a letter of Grant Thornton LLP dated a date
within two business days before the date of the Proxy Statement, and addressed
to Parent, in form and substance reasonably satisfactory to Parent and customary
in scope and substance for the "cold comfort" letters delivered by independent
public accountants in connection with proxy statements similar to the Proxy
Statement.

     Section 7.3  Regulatory Matters.  Each party hereto shall cooperate and use
its commercially reasonable efforts to promptly prepare and file all necessary
documentation, to effect all necessary applications, notices, petitions, filings
and other documents, and to use all commercially reasonable efforts to obtain no
later than the Initial Termination Date (as defined in Section 9.1(b)), as such
date may be extended pursuant to Section 9.1(b), all necessary permits,
consents, approvals and authorizations of all Governmental Authorities necessary
or advisable to consummate the transactions contemplated by this Agreement,
including, without limitation, the Company Required Statutory Approvals, the
Parent Required Statutory Approvals and the Legislative Actions. Notwithstanding
anything to the contrary contained in this Agreement, including this Section
7.3, neither Parent, nor any of Parent's Affiliates shall be required to divest
themselves of any of their respective assets or properties or agree to limit the
ownership or operation by Parent or any of Parent's Affiliates of any assets
including any of the assets of the Company and its Subsidiaries and Joint
Ventures.

     Section 7.4  Company Shareholders' Approval.

     (a) Company Special Meeting.  Subject to the provisions of Section 7.4(b),
the Company shall, as soon as reasonably practicable after the date hereof (i)
take all steps necessary to duly call, give notice of, convene and hold a
meeting of its shareholders (the "Company Special Meeting") for the purpose of
securing the Company Shareholders' Approval, (ii) distribute to its shareholders
the Proxy Statement in accordance with applicable federal and state law and with
its articles of incorporation and by-laws, (iii) subject to the fiduciary duties
of its Board of Directors, recommend to its shareholders the approval of this
Agreement and the transactions contemplated hereby, (iv) solicit from its
shareholders proxies in favor of the Merger and take all other action reasonably
necessary, or, in the reasonable opinion of Parent, advisable to secure the
Company Shareholders' Approval, and (v) cooperate and consult with Parent with
respect to each of the foregoing matters.

     (b) Meeting Date.  The Company Special Meeting for the purpose of securing
the Company Shareholders' Approval shall be held on such date as the Company and
Parent shall mutually determine.

     Section 7.5  Directors' and Officers' Indemnification.

     (a) Indemnification and Insurance.  For a period of six years after the
Effective Time, Parent will indemnify and hold harmless the present and former
officers and directors of the Company and its Subsidiaries

                                       23
<PAGE>   61

(the "Indemnified Parties") in respect of acts or omissions occurring prior to
the Effective Time to the extent provided under the Company's articles of
incorporation and by-laws in effect on the date hereof; provided, however, that
if any claim or claims are asserted or made within such six-year period, all
rights to indemnification in respect of such claims shall continue until the
final disposition of any and all such claims. For six years after the Effective
Time, Parent 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 the
Company'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, Parent will be obligated to obtain a
policy with the best coverage available, in the reasonable judgment of the Board
of Directors of Parent, for a cost not exceeding such amount.

     (b) Successors.  In the event Parent 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 Parent will assume the obligations set forth in this
Section 7.5.

     (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 the Company
and its Subsidiaries with respect to their activities as such prior to the
Effective Time, as provided in its respective articles of incorporation and
by-laws in effect on the date hereof, or otherwise in effect on the date hereof,
shall survive the Merger and shall continue in full force and effect for a
period of not less than six years from the Effective Time (or in the event any
relevant claim is asserted or made within such six-year period, until final
disposition of such claim).

     (d) Benefit.  The provisions of this Section 7.5 are intended to be for the
benefit of, and shall be enforceable by, each Indemnified Party, his or her
heirs and his or her representatives.

     Section 7.6  Disclosure Schedules.  On the date hereof, (a) Parent has
delivered to the Company a schedule (the "Parent Disclosure Schedule"),
accompanied by a certificate signed by an authorized officer of Parent stating
the Parent Disclosure Schedule is being delivered pursuant to this Section
7.6(a), and (b) the Company has delivered to Parent a schedule (the "Company
Disclosure Schedule"), accompanied by a certificate signed by an authorized
officer of the Company stating the Company Disclosure Schedule is being
delivered pursuant to this Section 7.6(b). The Company Disclosure Schedule and
the Parent Disclosure Schedule are collectively referred to herein as the
"Disclosure Schedules." The Disclosure Schedules constitute an integral part of
this Agreement and modify the respective representations, warranties, covenants
or agreements of the parties hereto contained herein to the extent that such
representations, warranties, covenants or agreements expressly refer to the
Disclosure Schedules. Anything to the contrary contained herein or in the
Disclosure Schedules notwithstanding, any and all statements, representations,
warranties or disclosures set forth in the Disclosure Schedules shall be deemed
to have been made on and as of the date hereof.

     Section 7.7  Public Announcements.  Subject to each party's disclosure
obligations imposed by law or the applicable regulations of any securities
exchange upon which such party's securities are listed, the Company and Parent
will cooperate with each other in the development and distribution of all news
releases and other public information disclosures with respect to this Agreement
or any of the transactions contemplated hereby and shall not issue any public
announcement or statement with respect hereto without the consent of the other
party (which consent shall not be unreasonably withheld).

     Section 7.8  Certain Employee Agreements.  Subject to Section 7.9, Parent
shall assume all contracts, agreements and collective bargaining agreements of
the Company and its Subsidiaries which apply to any current or former employee
or current or former director of the Company or any of its Subsidiaries;
provided, however, that the foregoing shall not prevent Parent from enforcing
such contracts, agreements and collective bargaining agreements in accordance
with their terms, including, without limitation, any reserved right to amend,
modify, suspend, revoke or terminate any such contract, agreement or collective
bargaining agree-

                                       24
<PAGE>   62

ment. It is the present intention of Parent and the Company that following the
Effective Time there will be no involuntary reductions in force at the Company
or its Subsidiaries, but that Parent will achieve workforce reductions through
attrition; however, Parent reserves the right to respond as it deems appropriate
based on business conditions and regulatory environments. If reductions in
workforce in respect of employees of the Company and its Subsidiaries become
necessary, they shall be made on a fair and equitable basis, in light of the
circumstances and the objectives to be achieved, giving consideration to
previous work history, job experience, qualifications, and business needs, and
any employees whose employment is terminated or jobs are eliminated by Parent
shall be entitled to participate on a fair and equitable basis in the job
posting programs offered by Parent. Any workforce reductions carried out
following the Effective Time by Parent shall be done in accordance with all
applicable collective bargaining agreements, and all applicable laws and
regulations governing the employment relationship and termination thereof
including, without limitation, the Worker Adjustment and Retraining Notification
Act and regulations promulgated thereunder, and any comparable state or local
law.

     Section 7.9  Employee Benefit Plans.

     (a) Except as may be required by applicable law, each Plan in effect on the
date hereof (or as amended or established in accordance with or as permitted by
this Agreement) shall be maintained in effect with respect to the employees,
former employees, directors or former directors of the Company and any of its
Subsidiaries who are covered by such plans, programs, agreements or arrangements
immediately prior to the Effective Time until Parent determines otherwise on or
after the Effective Time, and Parent shall assume as of the Effective Time each
Plan maintained by the Company immediately prior to the Effective Time and
perform such plan, program, agreement or arrangement in the same manner and to
the same extent that the Company would be required to perform thereunder;
provided, however, that nothing herein contained shall limit any reserved right
contained in any such Plan to amend, modify, suspend, revoke or terminate any
such plan, program, agreement or arrangement; provided, further, that, except as
may be required by applicable law, Parent or its Subsidiaries shall provide to
the employees of the Company and its Subsidiaries who are employed immediately
prior to the Effective Time and who are not covered by a collective bargaining
agreement ("Covered Company Employees") for a period of no less than 24 months
following the Effective Time, base salary levels, bonus opportunity levels and
employer-provided benefits under Qualified Plans, supplemental retirement
benefit plans which are not Qualified Plans and welfare plans that are
comparable in the aggregate to those provided immediately prior to the Effective
Time. Without limiting the foregoing, each Covered Company Employee who is a
participant in any Plan shall receive credit for purposes of eligibility to
participate, vesting and eligibility to receive benefits (but specifically
excluding for benefit accrual purposes) under any replacement benefit plan of
Parent or any of its Subsidiaries or Affiliates in which such employee becomes a
participant for service credited for the corresponding purpose under any such
Plan, unless such crediting of service would operate to cause any such plan or
agreement to fail to comply with the applicable provisions of the Code and ERISA
or other applicable law. Notwithstanding the foregoing, but subject to Section
7.9(b), Parent acknowledges that each Covered Company Employee who is a
participant in the Valley Gas Company Supplemental Retirement Plan (the "SERP")
as of the date hereof shall continue to accrue benefits for 24 months after the
Effective Time under terms at least as favorable as the terms of the SERP in
effect on the date of this Agreement, taking into account service and
compensation earned while employed by Parent and its Subsidiaries after the
Effective Time. After the 24 months immediately following the Effective Time,
Parent agrees to maintain during the next 24-month period, for Covered Company
Employees who continue their service with Parent, base salary levels, bonus
opportunity and employer-provided benefits under Qualified Plans, supplemental
retirement benefit plans which are not Qualified Plans and welfare plans that
are appropriate for the market given Parent's financial circumstances, the
industry in which it operates, and regulatory considerations. No provision
contained in this Section 7.9 shall be deemed to constitute an employment
contract between Parent or any of its Subsidiaries and any individual, or a
waiver of Parent's or any of its Subsidiaries' right to discharge any employee
at any time, with or without cause.

     (b) The Company shall take all necessary actions so that, effective no
later than immediately before the date the Company Shareholders' Approval is
obtained, (i) each of the SERP, the Morris Merchants, Inc. Executive Deferred
Compensation Plan and all other executive benefit plans and programs of the
Company and its Subsidiaries shall be amended to the extent necessary so that
any provisions therein that prohibit or

                                       25
<PAGE>   63

limit the amendment or termination thereof following a change of control do not
apply to individuals who are not participants therein as of the date of this
Agreement and (ii) subject to applicable law and the provisions of any
applicable collective bargaining agreement, each Qualified Plan shall be amended
to the extent necessary so that any provisions therein that call for the waiver
or elimination of vesting requirements upon or following a change in control
shall apply only to individuals who are participants therein immediately before
the Effective Time. Section 7.9(b) of the Company Disclosure Schedule sets forth
a list of all Plans which contain provisions that either (x) prohibit or limit
the amendment or termination thereof following a change of control, or (y) call
for the waiver or elimination of vesting requirements upon a change of control.

     (c) Parent will permit each of the Covered Company Employees to carry
forward all days of sick leave accrued prior to the Effective Time.

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

     Section 7.10  Company Stock Plans.  With respect to each Plan that provides
for benefits in the form of Company Common Stock ("Company Stock Plans"), the
Company and Parent shall take all corporate action necessary or appropriate to
(i) provide for the issuance or purchase in the open market of common stock of
Parent rather than Company Common Stock, pursuant thereto, and otherwise to
amend such Company Stock Plans to reflect this Agreement and the Merger, (ii)
obtain shareholder or board of director approval with respect to such Company
Stock Plans to the extent such approval is required for purposes of the Code or
other applicable law, or to enable such Company Stock Plans to comply with Rule
16b-3 promulgated under the Exchange Act, (iii) reserve for issuance under such
Company Stock Plans or otherwise provide a sufficient number of shares of Parent
Common Stock for delivery upon payment of benefits, grant of awards or exercise
of options under such Company Stock Plans and (iv) as soon as practicable after
the Effective Time, file registration statements on Form S-8 (or any successor
or other appropriate forms), with respect to the shares of Parent Common Stock
subject to such Company Stock Plans to the extent such registration statement is
required under applicable law, and Parent shall use its best efforts to maintain
the effectiveness of such registration statements (and maintain the current
status of the prospectuses contained therein) for so long as such benefits and
grants remain payable and such options remain outstanding. With respect to those
individuals who subsequent to the Merger will be subject to the reporting
requirements under Section 16(a) of the Exchange Act, the Company shall
administer the Company Stock Plans, where applicable, in a manner that complies
with Rule 16b-3 promulgated under the Exchange Act. This Section 7.10 shall not
limit any reserved right contained in any Plan to amend, modify, suspend, revoke
or terminate any such plan, program, agreement or arrangement.

     Section 7.11  Expenses.  Subject to Section 9.3, all costs and expenses
incurred in connection with this Agreement and the transactions contemplated
hereby shall be paid by the party incurring such expenses.

     Section 7.12  Further Assurances.  Each party will, and will cause its
Subsidiaries to, execute such further documents and instruments and, subject to
the last sentence of Section 7.3 take such further actions as may reasonably be
requested by any other party in order to consummate the Mergers in accordance
with the terms hereof.

     Section 7.13  Community Involvement.  For two years after the Effective
Time, Parent will make at least $60,000 per year in charitable contributions to
the communities served by the Company prior to the Merger and otherwise maintain
a substantial level of involvement in community activities in the State of Rhode
Island that is similar to, or greater than, the level of community development
and related activities carried on by the Company.

                                       26

     Section 7.14  Financial Statements to be Provided.  Upon Parent's request,
the Company shall (i) provide to Parent audited and unaudited financial
statements required to be included in (a) the proxy statements and the
registration statement contemplated by the Agreement of Merger, dated as of
October 4, 1999, by and between Parent and Fall River Gas Company and (b) the
proxy statement contemplated by the Agreement and Plan of Merger, dated as of
November 15, 1999, by and between Parent, GUS Acquisition Corporation and
Providence Energy Corporation, and (ii) cause its independent accountants to
deliver to Parent, Fall River Gas Company and Providence Energy Corporation the
required consents in connection therewith.

     Section 7.15  Officers of Valley Division.  From the Effective Time until
the earlier of their resignation, removal by Parent, or reassignment by Parent
in the event of a restructuring of the Valley Division, the following
individuals shall serve the Valley Division of the New England Business Unit of
Parent in the following capacities:
        Alfred P. Degen as President and Chief Executive Officer
        Charles K. Meunier as Vice President, Operations
        Richard G. Drolet as Vice President, Information Systems and Corporate

        Robert A. Young as Assistant Vice President and Chief Engineer

Parent expressly reserves the right to restructure the operations of the Valley
Division or the New England Business Unit at any time and from time to time in
any manner that it deems appropriate in its sole discretion.

                                   CONDITIONS

     Section 8.1  Conditions to Each Party's Obligation to Effect the
Mergers.  The respective obligations of each party to effect the Mergers shall
be subject to the satisfaction at or prior to the Closing of the following
conditions, except, to the extent permitted by applicable law, that such
conditions may be waived in writing pursuant to Section 9.5 by the joint action
of the parties hereto:

          (a) Shareholder Approval.  The Company Shareholders' Approval shall
     have been obtained.

          (b) No Injunction.  No temporary restraining order or preliminary or
     permanent injunction or other order by any federal or state court
     preventing consummation of the Mergers shall have been issued and be
     continuing in effect, and the Mergers and the other transactions
     contemplated hereby shall not have been prohibited under any applicable
     federal or state law or regulation.

     Section 8.2  Conditions to Obligation of Parent to Effect the Mergers.  The
obligation of Parent to effect the Mergers shall be further subject to the
satisfaction, at or prior to the Closing, of the following conditions, except as
may be waived by Parent in writing pursuant to Section 9.5:

          (a) Performance of Obligations of the Company.  The Company (and its
     appropriate Subsidiaries) shall have performed in all material respects its
     agreements and covenants contained in or contemplated by this Agreement to

          (b) Representations and Warranties.  The representations and
     warranties of the Company set forth in this Agreement shall be true and
     correct (i) on and as of the date hereof and (ii) on and as of the Closing
     Date with the same effect as though such representations and warranties had
     been made on and as of the Closing Date (except for representations and
     warranties that expressly speak only as of a specific date or time other
     than the date hereof or the Closing Date, which need only be true and
     correct as of such date or time) except in the case of clauses (i) and (ii)
     for such failures of representations or warranties to be true and correct

     such representations or warranties) which, individually and in the
     aggregate, would not be reasonably likely to result in a Company Material
     Adverse Effect.

          (c) Closing Certificates.  Parent shall have received a certificate
     signed by an authorized officer of the Company, dated the Closing Date, to
     the effect that the conditions set forth in Section 8.2(a) and Section
     8.2(b) of this Agreement have been satisfied.

          (d) Statutory Approvals.  The Company Required Statutory Approvals,
     the Parent Required Statutory Approvals and all other approvals, consents,
     opinions or rulings of Governmental Authorities required in order to
     consummate the transactions contemplated hereby, shall have been obtained,
     such approvals shall have become Final Orders (as defined below) and such
     Final Orders shall not impose terms or conditions which, individually or in
     the aggregate, would be reasonably likely to have a Company Material
     Adverse Effect or a material adverse effect on the business, operations,
     properties, financial condition or results of operation of Parent, or which
     would otherwise, in the reasonable determination of Parent, be unduly
     burdensome to Parent in a manner that would be, individually or in the
     aggregate, reasonably likely to have, a Company Material Adverse Effect or
     a material adverse effect on the business, operations, properties,
     financial condition or results of operation of Parent. A "Final Order"
     means an action by a Governmental Authority as to which: (a) no request for
     stay of the action is pending, no such stay is in effect and if any time
     period is permitted by statute or regulation for filing any request for
     such stay, such time period has passed; (b) no petition for rehearing,
     reconsideration or application for review of the action is pending and the
     time for filing any such petition or application has passed; (c) such
     Governmental Authority does not have the action under reconsideration on
     its own motion and the time in which such reconsideration is permitted has
     passed; and (d) no appeal to a court, or a request for stay by a court of
     the Governmental Authority's action is pending or in effect and the
     deadline for filing any such appeal or request has passed. The applicable
     waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of
     1976, as amended, with respect to the transactions contemplated hereby,
     shall have expired or been terminated.

          (e) No Company Material Adverse Effect.  No Company Material Adverse
     Effect shall have occurred, and there shall exist no fact or circumstance
     other than facts and circumstances disclosed in the Company SEC Reports
     delivered to Parent prior to the date of this Agreement which is reasonably
     likely to have a Company Material Adverse Effect.

          (f) Company Required Consents.  Each of the Company Required Consents
     shall have been obtained to the reasonable satisfaction of Parent, other
     than any such consents which, if not obtained, are not, individually or in
     the aggregate, reasonably likely to result in a Company Material Adverse
     Effect after the Closing. In addition, all consents and approvals required
     under the terms of any note, bond or indenture listed in Section 4.4(b) of
     the Company Disclosure Schedule to which the Company or any of its
     Subsidiaries is a party, shall have been obtained.

          (g) Resignations.  Each director of the Company, and each director of
     the Subsidiaries of the Company, shall resign or retire as a director of
     the applicable entity effective as of the Effective Time in accordance with
     such entity's organizational documents and applicable provisions of the
     RIBCA or other applicable state law, as the case may be; provided, however,
     that such resignations (but not retirements) shall not cause the
     termination of any such person's employment as an employee of the Company
     or its Subsidiaries.

          (h) Tax Good Standing.  Letters of Tax Good Standing shall have been
     obtained for the Company and its Subsidiaries from the Rhode Island
     Department of Taxation.

          (i) Company Bondholders' Consent.  All holders of each series of First
     Mortgage Bonds issued and outstanding under the Indenture of First
     Mortgage, dated as of December 15, 1992, between Valley, the Company, as
     Guarantor, and State Street Bank and Trust Company, as Trustee, and all
     holders of each series of debentures issued and outstanding under the
     Indenture between the Company and Mellon Bank, N.A., dated as of September
     1, 1997, each as amended or supplemented from time to time, shall have
     consented to such amendments to such Indentures as requested by Parent.

          (j) Legislative Actions.  The Legislative Actions shall have been
     completed.

     Section 8.3  Conditions to Obligation of the Company to Effect the
Mergers.  The obligation of the Company to effect the Mergers shall be further
subject to the satisfaction, on or prior to the Closing Date, of the following
conditions, except as may be waived by the Company in writing pursuant to
Section 9.5:

          (a) Performance of Obligations of Parent.  Parent shall have performed
     in all material respects its agreements and covenants contained in or
     contemplated by this Agreement to be performed by it at or prior to the
     Effective Time.

          (b) Representations and Warranties.  The representations and
     warranties of Parent set forth in this Agreement shall be true and correct
     (i) on and as of the date hereof and (ii) on and as of the Closing Date
     with the same effect as though such representations and warranties had been
     made on and as of the Closing Date (except for representations and
     warranties that expressly speak only as of a specific date or time other
     than the date hereof or the Closing Date, which need only be true and
     correct as of such date or time) except in the case of clauses (i) and (ii)
     for such failures of representations or warranties to be true and correct
     (without regard to any materiality qualifications contained in any of such
     representations and warranties) which, in the aggregate, would not be
     reasonably likely to result in a Parent Material Adverse Effect.

          (c) Statutory Approvals.  The Company Required Statutory Approvals and
     the Parent Required Statutory Approvals shall have been obtained. The
     applicable waiting period under the Hart-Scott-Rodino Antitrust
     Improvements Act of 1976, as amended, with respect to the transactions
     contemplated hereby, shall have expired or been terminated.

          (d) Closing Certificates.  The Company shall have received a
     certificate signed by an authorized officer of Parent, dated the Closing
     Date, to the effect that the conditions set forth in Section 8.3(a) and
     Section 8.3(b) of this Agreement have been satisfied.

                                   ARTICLE IX

                       TERMINATION, AMENDMENT AND WAIVER

          Section 9.1  Termination.  This Agreement may be terminated at any
     time prior to the Closing Date, whether before or after approval by the
     shareholders of the Company contemplated by this Agreement:

          (a) by mutual written consent of the Company and Parent;

          (b) by any party hereto, by written notice to the other parties, if
     the Effective Time shall not have occurred on or before the date that is 15
     months from the date hereof (the "Initial Termination Date"); provided,
     however, that if on the Initial Termination Date the conditions to the
     Closing set forth in Section 8.2(d), 8.3(c) or 8.2(j) shall not have been
     fulfilled but all other conditions to the Closing shall be fulfilled or
     shall be capable of being fulfilled, then the Initial Termination Date
     shall be extended to the 18-month anniversary of the date hereof; and
     provided, further, that the right to terminate this Agreement under this
     Section 9.1(b) shall not be available to any party whose failure to fulfill
     any obligation under this Agreement or whose breach of any agreement or
     covenant has been the cause of, or resulted directly or indirectly in, the
     failure of the Effective Time to occur on or before the Initial Termination
     Date or as it may be so extended;

          (c) by any party hereto, by written notice to the other parties, if
     the Company Shareholders' Approval shall not have been obtained at a duly
     held Company Special Meeting, including any adjournments thereof, by the
     Initial Termination Date;

          (d) by any party hereto, by written notice to the other parties if any
     state or federal law, order, rule or regulation is adopted or issued, which
     has the effect of prohibiting the Mergers, or by any party hereto if any
     court of competent jurisdiction in the United States or any State shall
     have issued an order, judgment or decree permanently restraining, enjoining
     or otherwise prohibiting the Mergers, and such order, judgment or decree
     shall have become final and nonappealable;

<PAGE>   67

          (e) by the Company prior to the time at which the Company
     Shareholders' Approval shall have been obtained, upon five days' prior
     written notice to Parent, if the Board of Directors of the Company
     determines in good faith that termination of this Agreement is necessary
     for the Board of Directors of the Company to act in a manner consistent
     with its fiduciary duties to shareholders under applicable law by reason of
     an Alternative Proposal meeting the requirements of Section 6.2 having been
     made; provided that

             (A) the Board of Directors of the Company shall determine based on
        advice of outside counsel with respect to the Board of Directors'
        fiduciary duties that notwithstanding a binding commitment to consummate
        an agreement of the nature of this Agreement entered into in the proper
        exercise of its applicable fiduciary duties, and notwithstanding all
        concessions which may be offered by Parent in negotiation entered into
        pursuant to Section 6.2(b), it is necessary pursuant to such fiduciary
        duties that the directors reconsider such commitment as a result of such
        Alternative Proposal;

             (B) the other provisions of Section 6.2(b) have been complied with
        by the Company; and

             (C) the Company's ability to terminate this Agreement pursuant to
        Section 9.1(e) is conditioned upon the payment by the Company to Parent
        of the amounts owed by it pursuant to Section 9.3;

          (f) by the Company, by written notice to Parent, if (i) there exist
     breaches of the representations and warranties of Parent made herein as of
     the date hereof which breaches, individually or in the aggregate, would or
     would be reasonably likely to result in a Parent Material Adverse Effect,
     and such breaches shall not have been remedied within 20 days after receipt
     by Parent of notice in writing from the Company, specifying the nature of
     such breaches and requesting that they be remedied, or (ii) Parent shall
     have failed to perform and comply with, in all material respects, its
     agreements and covenants hereunder, and such failure to perform or comply
     shall not have been remedied within 20 days after receipt by Parent of
     notice in writing from the Company, specifying the nature of such failure
     and requesting that it be remedied;

          (g) by Parent, by written notice to the Company, if (i) there exist
     breaches of the representations and warranties of the Company made herein
     as of the date hereof which breaches, individually or in the aggregate,
     would or would be reasonably likely to result in a Company Material Adverse
     Effect, and such breaches shall not have been remedied within 20 days after
     receipt by the Company of notice in writing from Parent, specifying the
     nature of such breaches and requesting that they be remedied, (ii) the
     Company (or its appropriate Subsidiaries) shall not have performed and
     complied with its agreements and covenants contained in Sections 6.1(b) and
     6.1(c) or shall have failed to perform and comply with, in all material
     respects, its other agreements and covenants hereunder, and such failure to
     perform or comply shall not have been remedied within 20 days after receipt
     by the Company of notice in writing from Parent, specifying the nature of
     such failure and requesting that it be remedied, or (iii) the Board of
     Directors of the Company or any committee thereof (A) shall withdraw or
     modify or proposes to withdraw or modify in any manner adverse to Parent
     its approval or recommendation of this Agreement or the transactions
     contemplated hereby, (B) shall fail to reaffirm such approval or
     recommendation upon Parent's request within two days of such request, (C)
     shall approve or recommend any acquisition of the Company or any of its
     Subsidiaries or a material portion of their respective assets or any tender
     offer for the shares of capital stock of the Company or any of its
     Subsidiaries or any other Alternative Proposal, in each case by a party
     other than Parent or any of its Affiliates, (D) causes the Company or any
     of its Subsidiaries to enter into a definitive agreement related to the
     Alternative Proposal or (E) shall resolve to take any of the actions
     specified in clause (A), (B), (C) or (D); or

          (h) by Parent, by written notice to Company, if a third party,
     including a group (as defined under the Exchange Act), acquires securities
     representing greater than 50% of the voting power of the outstanding voting
     securities of Company.

     Section 9.2  Effect of Termination.  In the event of termination of this
Agreement by either the Company or Parent pursuant to Section 9.1, there shall
be no liability on the part of any party or its Affiliates, shareholders,
officers or directors, agents or other representatives hereunder; provided,
however, that (i) any

                                       30
<PAGE>   68

fee payable under Section 9.3 is paid to Parent and (ii) no such termination
shall relieve any party of 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 and (iii) the agreement contained in the last sentence
of Section 7.1(a) and Sections 7.11, 9.3, 10.3, 10.4, 10.5, 10.6, 10.7, 10.8,
10.9 and 10.10 shall survive any termination of this Agreement.

     Section 9.3  Termination Fee; Expenses.

     (a) The Company shall pay Parent a fee of $5.0 million in cash
("Termination Fee") upon the termination of this Agreement by the Company
pursuant to Section 9.1(e) or by Parent pursuant to Section 9.1(g)(iii) or
9.1(h).

     (b) Liquidated Damages; Prompt Payment.  The parties agree that the
agreements contained in this Section 9.3 are an integral part of the
transactions contemplated by the Agreement and constitute liquidated damages and
not a penalty. If the Company fails to pay promptly to Parent the fee due under
Section 9.3, in addition to any amounts paid or payable pursuant to Section 9.3,
the Company 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 at 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.

     Section 9.4  Amendment.  This Agreement may be amended by the Boards of
Directors of the parties hereto, at any time before or after approval hereof by
the shareholders of the Company and prior to the Effective Time, but after such
approvals, no such amendment shall (a) alter or change the amount of the Merger
Consideration, or (b) alter or change any of the terms and conditions of this
Agreement if any of the alterations or changes, alone or in the aggregate, would
materially adversely affect the rights of holders of Company capital stock,
except for alterations or changes that could otherwise be adopted by the Board
of Directors of the Company, without the further approval of such shareholders.
This Agreement may not be amended except by an instrument in writing signed on
behalf of each of the parties hereto.

     Section 9.5  Waiver.  At any time prior to the Effective Time, the parties
hereto may (a) extend the time for the performance of any of the obligations or
other acts of the other parties hereto, (b) waive any inaccuracies in the
representations and warranties contained herein or in any document delivered
pursuant hereto and (c) waive compliance with any of the agreements or
conditions contained herein, to the extent permitted by applicable law. Any
agreement on the part of a party hereto to any such extension or waiver shall be
valid if set forth in an instrument in writing signed on behalf of such party.
Except as otherwise expressly provided in this Agreement, neither the failure
nor any delay on the part of any party to exercise any right, power or privilege
hereunder shall operate as a waiver thereof, nor shall any single or partial
exercise or waiver of any such right, power or privilege preclude any other or
further exercise thereof, or the exercise of any other right, power or privilege
available to each party at law or in equity.

                                                               November 30, 1999

Board of Directors
Valley Resources, Inc.
1595 Mendon Road
Cumberland, RI 02864

Ladies and Gentlemen:

     Valley Resources, Inc. (the "Company"), Southern Union Company (the
"Acquiring Company") and SUG Acquisition Corporation, a wholly-owned subsidiary
of the Acquiring Company (the "Purchaser"), propose to enter into an agreement
(the "Agreement") pursuant to which the Company will be merged with and into the
Purchaser in a transaction (the "Merger") in which each share of the Company's
common stock (the "Shares") will be converted into the right to receive $25.00
in cash.

     You have asked us whether or not, in our opinion, the proposed cash
consideration to be received by the shareholders of the Company pursuant to the
Merger is fair to the shareholders of the Company from a financial point of
view.

In arriving at the opinion set forth below, we have, among other things:

     (1) Reviewed the Company's Annual Reports, Forms 10-K and related financial
         information for the five fiscal years ended August 31, 1999;

     (2) Reviewed certain information, including financial forecasts, relating
         to the business, earnings, cash flow, assets and prospects of the
         Company, furnished to us by the Company;

     (3) Conducted discussions with members of senior management of the Company
         concerning its businesses and prospects;

     (4) Reviewed the historical market prices and trading activity for the
         Shares and compared them with that of certain publicly traded companies
         which we deemed to be relevant;

     (5) Compared the results of operations of the Company with that of certain
         companies which we deemed to be relevant;

     (6) Compared the proposed financial terms of the transactions contemplated
         by the Agreement with the financial terms of certain other mergers and
         acquisitions which we deemed to be relevant;

     (7) Reviewed a draft of the Agreement dated November 30, 1999; and

     (8) Reviewed such other financial studies and analyses and performed such
         other investigations and took into account such other matters as we
         deemed necessary, including our assessment of general economic, market
         and monetary conditions.

     In preparing our opinion, we have relied on the accuracy and completeness
of all information supplied or otherwise made available to us by the Company,
and we have not assumed any responsibility to independently verify such
information. With respect to the financial forecasts examined by us, we have
assumed that they were reasonably prepared and reflect the best currently
available estimates and good faith judgments of the management of the Company as
to the future performance of the Company. We have also relied upon assurances of
the management of the Company that they are unaware of any facts that would make
the information or financial forecasts provided to us incomplete or misleading.
We have not made any independent
<PAGE>   73

evaluation or appraisal of the assets or liabilities (contingent or otherwise)
of the Company nor have we been furnished with any such evaluations or
appraisals. We have also assumed with your consent, that (i) the Merger will be
accounted for under the purchase method of accounting, and (ii) any material
liabilities (contingent or otherwise, known or unknown) of the Company are as
set forth in the consolidated financial statements of the Company. This opinion
does not constitute a recommendation to any shareholder of the Company as to how
any such shareholder should vote on the Merger. This opinion does not address
the relative merits of the Merger and any other transactions or business
strategies discussed by the Board of Directors of the Company as alternatives to
the Merger or the decision of the Board of Directors of the Company to proceed
with the Merger. Our opinion is based on economic, monetary and market
conditions existing on the date hereof.

     In the ordinary course of business, PaineWebber Incorporated may trade in
the securities of the Company and the Acquiring Company for our own account and
for the accounts of our customers and, accordingly, may at any time hold long or
short positions in such securities.

     PaineWebber Incorporated is currently acting as financial advisor to the
Company in connection with the Merger and will be receiving a fee in connection
with the rendering of this opinion and upon consummation of the Merger.

     On the basis of, and subject to the foregoing, we are of the opinion that
the proposed cash consideration to be received by the shareholders of the
Company pursuant to the Merger, taken as a whole, is fair to such shareholders
from a financial point of view.

     This opinion has been prepared for the information of the Board of
Directors of the Company in connection with the Merger and shall not be
reproduced, summarized, described or referred to, provided to any person or
otherwise made public or used for any other purpose without the prior written
consent of PaineWebber Incorporated, provided, however, that this letter may be
reproduced in full in the Proxy Statement related to the Merger.

                                          Very truly yours,

                                          PAINEWEBBER INCORPORATED
