                                 WITNESSETH:

      WHEREAS, Berkshire Gas has an authorized capitalization consisting of 
(i) 4,600,000 shares of common stock, par value $2.50 per share ("Berkshire 
Gas Common Stock"), of which 2,269,821 shares are issued and outstanding and 
115,432  shares have been reserved for issuance pursuant to Berkshire Gas's 
Share Owner Dividend Reinvestment and Stock Purchase Plan; and (ii) 105,000 
shares of cumulative preferred stock, par value $100.00 per share 
("Berkshire Gas Preferred Stock"), 3,212 shares of which are issued and 
outstanding; the number of shares of issued and outstanding Berkshire Gas 
Common Stock being subject to increase to the extent that shares reserved 
for issuance are issued prior to the Effective Time (as defined below) of 
the Merger;

      WHEREAS, Mergeco has an authorized capitalization consisting of 
200,000 shares of common stock, par value $1.00 per share ("Mergeco Common 
Stock"), of which 100 shares have been subscribed for by Holdco and, once 
the issuance thereof has been approved by the Massachusetts Department of 
Telecommunications and Energy as required by law, will be issued to and 
owned beneficially and of record by Holdco;

      WHEREAS, Holdco has an authorized capitalization consisting of (i) 
10,000,000 shares of beneficial interest, without par value ("Holdco Common

outstanding and owned beneficially and of record by Berkshire Gas; and (ii) 
1,000,000 preferred shares, par value $100.00 per share, of which no shares 
are issued and outstanding; and

      WHEREAS, the Boards of Directors or the Board of Trustees of the 
respective parties hereto deem it advisable and in the best interests of 
Berkshire Gas and its shareholders to merge Mergeco with and into Berkshire 
Gas (the "Merger") in accordance with Section 96 of Chapter 164 of the 
Massachusetts General Laws and pursuant to this Agreement and the Articles 
of Merger attached hereto as ANNEX I and incorporated herein (the 
"Articles"), whereby the holders of shares of Berkshire Gas Common Stock 
will exchange their shares for Holdco Common Shares;

      NOW, THEREFORE, in consideration of the premises and the 
representations, warranties and agreements herein contained, the parties 
hereto agree that Mergeco shall be merged with and into Berkshire Gas, which 
shall be the corporation surviving the Merger, and that the terms and 
conditions of the Merger, the mode of carrying it into effect, and the 
manner of converting and exchanging shares shall be as follows:


                                  ARTICLE I

Agreement, the Articles shall be executed and acknowledged by each of 
Berkshire Gas and Mergeco and thereafter delivered to the Secretary of State

of Chapter 164 of the Massachusetts General Laws.  The Merger shall become 
effective at such time as the Articles are filed as required by law with the 
Secretary of State of The Commonwealth of Massachusetts or such date, not 
more than thirty days after such filing, as may be specified in the Articles 
(the "Effective Time").  At the Effective Time, the separate existence of

      (b)  Prior to and after the Effective Time, Holdco, Berkshire Gas and

shall issue the Holdco Common Shares which the holders of Berkshire Gas 
Common Stock are entitled to receive as provided in Article II hereof.  In 
the event that at any time after the Effective Time any further action is 
necessary or desirable to carry out the purposes of this Agreement and to 
vest the Surviving Corporation with full title to all properties, assets, 
rights, approvals, immunities and franchises of either of the Constituent 
Corporations, the officers and directors of each of the Constituent 
Corporations as of the Effective Time shall take all such further action.


                                 ARTICLE II
                 TERMS OF CONVERSION AND EXCHANGE OF SHARES

At the Effective Time:

      (a)  Each share of Berkshire Gas Common Stock issued and outstanding 
immediately prior to the Merger thereupon shall be changed and converted 
into one Holdco Common Share, which thereupon shall be issued, fully paid 
and nonassessable;

      (b)  The shares of Berkshire Gas Preferred Stock issued and 
outstanding immediately prior to the Merger shall not be converted or 
otherwise affected by the Merger, and each such share shall continue to be 
issued and outstanding and to be one fully paid and nonassessable share of 
the particular series of preferred stock of the Surviving Corporation;

      (c)  Each share of Mergeco Common Stock issued and outstanding 
immediately prior to the Merger shall be converted into one share of common 
stock of the Surviving Corporation, which thereupon shall be issued, fully 
paid and nonassessable; and

      (d)  Each Holdco Common Share issued and outstanding immediately prior 
to the Merger shall be canceled.


                                 ARTICLE III
                     ARTICLES OF ORGANIZATION AND BYLAWS

      From and after the Effective Time, and until thereafter amended as 
provided by law, the Articles of Organization of Berkshire Gas as in effect 
immediately prior to the Merger shall be and continue to be the Articles of 
Organization of the Surviving Corporation.  The purposes of the Surviving 
Corporation, the total number of shares and par value of each class of stock 
which the Surviving Corporation is authorized to issue and a description of 
each class of stock authorized at the Effective Time, with the preferences, 
voting powers, qualifications, special or relative rights or privileges as 
to each class and any series thereof then established, are as stated in such 
Articles of Organization, which are attached hereto as Annex II and 


 50
incorporated herein.  From and after the Effective Time, the Bylaws of 
Berkshire Gas shall be and continue to be the Bylaws of the Surviving 
Corporation until amended in accordance with law.


                                 ARTICLE IV
                           DIRECTORS AND OFFICERS

      The persons who are directors and officers of Berkshire Gas 
immediately prior to the Merger shall continue as directors and officers, 
respectively, of the Surviving Corporation and shall continue to hold office 
as provided in the Bylaws of the Surviving Corporation.  If, at or following 
the Effective Time, a vacancy shall exist in the Board of Directors or in 
the position of any officer of the Surviving Corporation, such vacancy may 
be filled in the manner provided in the Bylaws of the Surviving Corporation.


                                  ARTICLE V
                             STOCK CERTIFICATES

      Following the Effective Time, each holder of an outstanding 
certificate or certificates theretofore representing shares of Berkshire Gas 
Common Stock may, but shall not be required to, surrender the same to Holdco 
for cancellation or transfer, and each such holder or transferee will be 
entitled to receive certificates representing the same number of Holdco 
Common Shares as shares of Berkshire Gas Common Stock previously represented 
by the surrendered stock certificates.  Until so surrendered or presented 
for transfer, each outstanding certificate which, prior to the Effective 
Time, represented Berkshire Gas Common Stock shall be deemed and treated for 
all corporate purposes to represent the ownership of the same number of 
Holdco Common Shares as though such surrender or transfer and exchange had 
taken place.  The stock transfer books for the Berkshire Gas Common Stock 
shall be deemed to be closed at the Effective Time and no transfer of 
outstanding shares of Berkshire Gas Common Stock outstanding prior to the 
Effective Time shall be made thereafter on such books.


                                 ARTICLE VI

forth in Article VI hereof and the authority to terminate this Agreement as 
set forth in Article VII hereof, the Constituent Corporations and Holdco 
shall do all such acts and things as shall be necessary or desirable in 
order to make the Effective Time occur as soon thereafter as practicable.

                                 ARTICLE IX
