                      FALL RIVER GAS COMPANY AND SUBSIDIARY
                      MANAGEMENT'S DISCUSSION AND ANALYSIS

Results of Operations

         Net income for the first quarter of fiscal 1999 was $341,000 or $0.16
per share as compared with earnings of $548,000 or $0.27 for the first quarter
in fiscal 1998. Basic earnings per share, for the three month period, have been
impacted by the warmer weather recorded in fiscal 1999 as compared to the first
quarter fiscal 1998. Effective degree days as stated below show a 13.8% decrease
from the previous fiscal year.
         Gas operating revenues for the three months ended December 31, 1998
reflect a decrease of 6.9% or $777,700. Revenues decreased from $11,272,800
recorded in fiscal 1998 to $10,495,100, mainly due to a 17.6% decrease in firm
sales volume due to warmer weather in which effective degree days decreased from
2,259 to 1,947. Firm sales volume for three months ended December 31, 1998 is
1,196,817 MCF as compared to the 1,452,329 MCF reported in fiscal 1998. Total
sales for the three month period which include Interruptible customers,
Interruptible Transportation and Transportation customers, decreased 9.9% from
1,851,427 MCF to 1,666,604 MCF in 1998. Cost of gas (CGA) revenues for the three
months ended December 31, 1998 decreased by $769,000 or 10.4%. Revenues
decreased from $7,391,800 recorded in fiscal 1998 to $6,622,700 in fiscal 1999
due to the net differences in our CGA decimal along with decreased firm sales
volume as stated above. The fiscal 1999 and 1998 CGA revenues, referred to
above, have been computed on the current rate structure. In accordance with the
Company's approved CGAC increases or decreases in the cost of gas sold continue
to be passed directly to our firm customers, dollar for dollar.
         Total operating expenses, excluding federal and state income taxes, for
the three month comparisons reflected a 3.6% decrease from $10,310,000 to
$9,943,800 a decrease of $366,200. The most significant operation expense, cost
of gas sold, decreased by $391,700 for the three month comparison due mainly to
the decrease in the volumes of purchased gas and the lower commodity cost. Other
operation expenses including health benefits, payroll, and materials and
supplies have increased by $9,700, which was .3% higher than the comparable
period in fiscal 1998.
         Interest expense decreased by $74,500, 15.3%, for the three month
comparison as a result of decreased short term borrowing due to an equity and
debt financing. As reported, on October 31, 1997 the Company issued 340,000
shares of common stock and began trading on the American Stock Exchange (AMEX)
under the symbol "FAL". On November 26, 1997 the underwriter of this equity
issue, First Albany Corporation, exercised its over-allotment option to sell an
additional 50,000 shares of common stock. The net proceeds of this offering of
approximately $4,700,000 were used to reduce short-term borrowings. The Company
also issued $6,000,000 of long-term debt with a coupon rate of 7.24% on December
12, 1997 through a private placement. The net proceeds from this offering was
also used to reduce short-term borrowings.

Capital Resources and Liquidity
                                        4
<PAGE>


         The Company's major capital requirement results from upgrading the
efficiency of existing plant, as well as, to serve additional customers. For the
three months ended December 31, 1998, capital expenditures totaled approximately
$615,000.
         Cash flow patterns reflect the seasonality of the Company's business.
The greatest demand for cash is in the late fall and winter as construction
projects are brought to completion and accounts receivable balances rise.
         Capital expenditures and accounts receivable balances were financed by
internally generated funds and supplemented by short- term borrowings.

Factors that May Affect Future Results

         The Private Securities Litigation Reform Act of 1995 encourages the use
of cautionary statements accompanying forward-looking statements. The preceding
Management's Discussion and Analysis of Financial Condition and Results of
Operations includes forward-looking statements concerning the impact of changes
in the cost of gas and of the CGA mechanism on total margin; projected capital
expenditures and sources of cash to fund expenditures; and estimated costs of
environmental remediation and anticipated regulatory approval of recovery
mechanisms. The Company's future results, generally and with respect to such
forward-looking statements, may be affected by many factors, among which are
uncertainty as to the regulatory allowance of recovery of changes in the cost of
gas; uncertain demands for capital expenditures and the availability of cash
from various sources; uncertainty as to whether transportation rates will be
reduced in future regulatory proceeding with resulting decreases in
transportation margins; and uncertainty as to regulatory approval of the full
recovery of environmental costs, transition costs and other regulatory assets.

New Accounting Standards

         The Company has adopted Statement of Financial Accounting Standards No.
128, "Earnings per Share," effective quarter ended December 31, 1997 and has
reflected basic earnings per share on the face of the statements of income.

The "Year 2000" Issue

         The Company has evaluated its principal computer systems and
noninformation technology systems including, but not limited to,
telecommunications systems, automated meter reading systems, SCADA, regulator
stations, plant remote control systems and security systems to determine
readiness for the year 2000. These systems are currently capable of processing
the year 2000, or are in the process of being upgraded or replaced by systems
that are similarly capable. All necessary program modifications and system
upgrades and testing are expected to be completed by the year 2000. Costs
incurred to date and costs expected to be incurred to complete the year 2000
readiness are not significant and will not have a material impact on the
Company's financial position or results of operations. The Company is currently
assessing year
                                       5

2000 issues with material third parties. Except for the Company's major pipeline
supplier, who has provided assurance of compliance, the Company has not
determined the level of third-party risk. Preparation of a contingency plan is
in process and is expected to be finalized during fiscal year 1999.
