suspension of the Plan or thereafter shall be paid by Registrant in cash and no

- ---------------------------------------------

August   , 2000

Dear Shareholder:

As you know, the Company has been pleased to offer its shareholders a Share
Owner Dividend Reinvestment and Stock Purchase Plan (the "Plan") whereby holders
of record of common stock of the Company are provided with a simple and
convenient method of investing cash dividends and/or optional cash payments in
additional shares of common stock of the Company. This Plan has proven to be
quite popular with shareholders, and we sincerely appreciate your participation.

The anticipated close of the Company's merger with Southern Union Company is
currently scheduled for mid September 2000. Due to the proximity of the dates of
the anticipated merger and the additional cash purchases under the Plan for
September 2000, the Company's Board of Directors has suspended the Plan
effective September 1, 2000. All dividends payable after suspension of the Plan
shall be paid in cash and NO ADDITIONAL CASH PURCHASES OF COMMON STOCK OF THE
COMPANY UNDER THE PLAN WILL BE ALLOWED FOLLOWING SUSPENSION OF THE PLAN.

Please feel free to direct any questions that you might have about this matter,
or comments, to Peter H. Thanas, Senior Vice President and Treasurer at the
Company at (508) 689-1142.

Thank you for your continuing interest in the Fall River Gas Company.

Sincerely,

/S/ PETER H. THANAS
