                       CAMBRIDGE ELECTRIC LIGHT COMPANY

                                    PART I.

Item 1. Business

    General

    Cambridge Electric Light Company (the Company) is engaged in the
production, distribution and sale of electricity at retail to approximately
44,400 customers in the city of Cambridge, Massachusetts.  The service
territory encompasses a seven square mile area with a population of
approximately 96,000.  In addition, the Company sells power for resale to the
New England Power Pool (NEPOOL) and the Town of Belmont, Massachusetts
(Belmont), and sells steam from its electric generating stations at wholesale
to an affiliated company for distribution to customers for space heating and
other purposes.

    The Company, which was organized on January 28, 1886 pursuant to a special
act of the legislature of the Commonwealth of Massachusetts, operates under
the jurisdiction of the Massachusetts Department of Public Utilities (DPU),
which regulates retail rates, accounting, issuance of securities and other
matters.  The Company also files its wholesale rates with the Federal Energy
Regulatory Commission (FERC).  The Company is a wholly-owned subsidiary of
Commonwealth Energy System (System), which, together with its subsidiaries, is
referred to as "the system."

    By virtue of its charter, which is unlimited in time, the Company
distributes electricity without direct competition in kind from any privately
or municipally-owned utility.  Alternate sources of energy are available to
customers within the service territory.  In early 1995, the Massachusetts
Institute of Technology, one of the Company's largest customers, completed and
placed into service a natural gas cogeneration facility which will meet
approximately 94% of its power needs.  For further information on this
facility refer to the "Customer Transition Charge" section discussion which
follows.

    Of the Company's 1996 retail electric unit sales, 12.5% was sold to
residential customers, 81.4% to commercial customers, 5.5% to industrial
customers and 0.6% to municipal and other customers.

    Electric Power Supply

    The Company owns generating facilities with a total capacity of 112.5 MW,
of which 49.5 MW is used for peaking purposes.  The Company relies primarily
on purchased power to meet its energy requirements.

    Power purchases for the Company and Commonwealth Electric Company (Common-
wealth Electric), the other wholly-owned electric distribution subsidiary of
the System, are arranged in accordance with their requirements.  These
arrangements include purchases from Canal Electric Company (Canal), another
wholly-owned subsidiary of the System.  Canal is a wholesale electric
generating company located in Sandwich, Massachusetts and is an important
source of purchased power for the Company.  Under long-term contracts, system
entitlements include one-quarter (141.5 MW) of the capacity and energy of
Canal Unit 1 and one-half (290 MW) of the capacity and energy of Canal Unit 2.

<PAGE>
<PAGE 4>

                       CAMBRIDGE ELECTRIC LIGHT COMPANY

The Company's entitlements in these units are 28.2 MW and 57.8 MW,
respectively.

    Pursuant to a Capacity Acquisition and Disposition Agreement (CADA), Canal
seeks to secure bulk electric power on a single system basis to provide cost
savings for the customers of the Company and Commonwealth Electric.  The CADA
has been accepted for filing as an amendment to Canal's FERC rate schedule and
allows Canal to act on behalf of the Company and Commonwealth Electric in the
procurement of additional capacity for one or both companies.  The CADA is in
effect for Seabrook 1 and Phases I and II of Hydro-Quebec.  Exchange agree-
ments are in place with these utilities whereby, in certain circumstances, it
is possible to exchange capacity so that the mix of power improves the pricing
for dispatch for both the seller and the purchaser.  Power contracts are in
place whereby Canal bills or credits the Company and Commonwealth Electric for
the costs or revenues associated with these facilities.  The Company and
Commonwealth Electric, in turn, have billed or are billing these charges (net
of revenues from sales) to their customers through rates subject to DPU
approval.

    The Company also has equity ownership interests (2 1/2% to 4%) in two
operating nuclear units located in New England with power entitlements
totaling 42.4 MW.  One of the operating nuclear units, located in Wiscasset,
Maine and operated by Maine Yankee Atomic Power Company (Maine Yankee),
experienced two outages due to design and regulatory issues during 1996.  On
July 20, 1996 the unit was taken off-line to address a design issue on the
primary component cooling system.  The unit remained off-line until September
2, 1996, to also address issues related to compliance with the Nuclear
Regulatory Commission's (NRC) General Letter 96-01 that addresses surveillance
testing of safety system components.

    The second outage at Maine Yankee began on December 5, 1996 to correct
technical issues associated with a Confirmatory Action Letter issued by the
NRC.  Maine Yankee also used this outage as an opportunity to breach the
reactor and identify specific fuel assemblies which were detected as leaking
earlier in the operating cycle.  They identified eight assemblies with a total
of seventy-five fuel rods leaking, and found the most recent load of fuel
unacceptable for continued operation of the plant.  Additional cable
separation issues were also identified and the NRC has expanded the
requirements of the Confirmatory Action Letter that Maine Yankee must meet
prior to restart.  The restart date of the unit has not yet been determined.

    In July 1996, Connecticut Yankee Atomic Power Company (Connecticut
Yankee), which operates the Connecticut Yankee nuclear power plant, took the
unit out of service in connection with certain safety related issues and
refueling.  On December 4, 1996, following an economic evaluation of
continuing operation of the plant over the remaining ten years of its license
life compared to ceasing operation and incurring replacement power costs for
the same period, Connecticut Yankee's Board of Directors voted to permanently
shut down the plant.

    Additionally, in February 1992, Yankee Atomic Electric Company's Board of
Directors decided to permanently cease power operation at a nuclear unit
located in Rowe, Massachusetts and, in time, decommission the facility.  The
Company has a 2% interest in this facility.  For further information, refer to

Note 3(e) of Notes to Financial Statements filed under Item 8 of this report.

    In addition, the Company has entitlements of 19.7 MW and 8.1 MW through
Canal's equity ownership in Hydro-Quebec Phase II and joint-ownership in the
Seabrook nuclear unit, respectively.

    The Company expects to provide for future peak load plus reserve require-
ments through existing system generation, including purchasing excess capacity
from neighboring utilities.  These and other bulk electric power purchases are
necessary in order to fulfill the system's NEPOOL obligation and for Canal to
acquire and deliver electric generating capacity to meet the Company's and
Commonwealth Electric's requirements.

    New England Power Pool

    The Company, together with other electric utility companies in the New
England area, is a member of NEPOOL, which was formed in 1971 to provide for
the joint planning and operation of electric systems throughout New England.

    NEPOOL operates a centralized dispatching facility to ensure reliability
of service and to dispatch the most economically available generating units of
member companies to fulfill the region's energy requirements.  This concept is
accomplished through the use of computers to monitor and forecast load
requirements.

    The Company and the System's other electric subsidiaries are also members
of the Northeast Power Coordinating Council (NPCC), an advisory organization,
which includes the major power systems in New England and New York plus the
provinces of Ontario and New Brunswick in Canada.  The NPCC establishes cri-
teria and standards for reliability and serves as a vehicle for coordination
in the planning and operation of these systems.

    The reserve requirements used by NEPOOL participants in planning future
additions are determined by NEPOOL to meet the reliability criteria recom-
mended by the NPCC.  The system estimates that, during the next ten years,
reserve requirements so determined will be approximately 20% of peak load.

    Energy Mix

    The Company's energy mix, including purchased power, was as follows:

                                     1996       1995      1994

        Oil                           21%        23%       31%
        Nuclear                       39         36        43
        Natural gas                   33         40        25
        Hydro                          7          1         1
          Total                      100%       100%      100%

    The increase in hydro during 1996 represents an increase in power from
Hydro-Quebec, while the decrease in oil represents a five-month maintenance
outage at Canal Unit 2.  The lower oil component in 1995 reflects Canal Unit 1
being off-line for the first seven months of the year and an additional outage
period of nearly one month during the fourth quarter.  In addition to power
purchases, the Company is actively pursuing sales of certain available

capacity to utilities in and outside the New England region.

    Regulation

    (a) Wholesale Rate Proceedings

    The Company provides power supply and transmission services to its FERC-
jurisdictional wholesale customers.  The Company requires FERC approval to
change its wholesale rates, including those to the Municipal Light Department
of the Town of Belmont, Massachusetts (Belmont), a "partial requirements"
customer since 1986.  Since February 1993, Belmont has taken power supply
service under a FERC approved Net Requirements Power Supply Agreement.

    In 1993, the Company and Belmont began negotiations for a new transmission
service agreement.  The negotiations were not successful.  On June 29, 1994
the Company filed for FERC approval of a new transmission service agreement
with Belmont.  The FERC accepted the rates effective January 25, 1995, subject
to refund.  At the same time, an investigation was opened by the FERC to
determine the reasonableness of both the existing transmission tariff rates to
Belmont and the proposed transmission service agreement with Belmont.  Both
Belmont and FERC staff intervened in the investigation.  The Company filed its
case with the FERC on October 25, 1994 and evidentiary hearings were held in
March 1995.

    An Initial Decision (ID) of the Presiding Administrative Law Judge was
issued on September 14, 1995.  In the ID the Administrative Law Judge found
that the Company's existing transmission tariff rates were just and
reasonable.  The Administrative Law Judge identified a number of revisions to
the filed transmission service agreement which effectively reduced the rates
to Belmont.  In October 1995, the parties filed briefs on exceptions to the
Administrative Law Judge's ID.  The Company awaits final FERC action on this
investigation.

    On March 29, 1995, the FERC issued two notices of proposed rulemaking
concerning open access transmission and stranded costs.  The FERC's notices
proposed to remove impediments to competition in the wholesale bulk power
marketplace and to bring more efficient, lower-cost power to consumers.  On
March 29, 1996 the Company filed Transmission Tariffs that implemented the
FERC's requirements for non-discriminatory open access transmission for both
point-to-point and network service.  The tariffs were accepted on May 17, 1996
to be effective on May 28, 1996, but the rates are subject to a Section 206
investigation issued by the FERC itself.  A settlement with the FERC regarding
this investigation was filed on February 6, 1997.

    On April 24, 1996 the FERC issued Order No. 888 a set of three
interrelated rules resolving the above rulemakings.  The FERC required all
public utilities that own, control or operate transmission facilities in 
interstate commerce to have on file wholesale open access transmission tariffs
that conform to the FERC pro-forma tariff contained in Order No. 888.  On July
9, 1996, the Company and Commonwealth Electric filed tariffs that conform to
the FERC's pro-forma tariffs.  On November 13, 1996, the FERC accepted the
non-rate terms and conditions of these tariffs effective July 9, 1996, subject
to a revision of one section dealing with the scheduling of services.

                       CAMBRIDGE ELECTRIC LIGHT COMPANY

    On December 31, 1996, the Company and Commonwealth Electric filed market-
based power sales tariffs with the FERC which received FERC approval on
February 27, 1997.  The Company and Commonwealth Electric seek to make
wholesale power sales at fully negotiated rates.  In addition, the Company and
Commonwealth Electric requested authorization to participate as brokers in the
sale and purchase of electricity.

    (b) Cost Recovery

        Rate Schedule

    The Company files a fuel charge (FC) rate schedule, subject to DPU
regulation, under which the Company is allowed current recovery from retail
customers of costs of fuel used in electric generation and a substantial
portion of purchased power, demand and transmission costs.  This schedule
requires the quarterly computation and DPU approval of a FC decimal based on
forecasts of fuel, electricity purchased for resale and transmission costs and
billed unit sales for each period.  To the extent that collections under the
rate schedule do not match actual costs for a given calendar quarter, an
appropriate adjustment is reflected in the calculation of the Company's
decimal for the next calendar quarter.

        Purchased Power

    The Company has long-term contracts for the purchase of electricity from
various sources.  Generally, these contracts are for fixed periods and require
that the Company pay a demand charge for its capacity entitlement and an
energy charge to cover the cost of fuel.  The Company collects a portion of
the capacity-related purchased power costs associated with certain long-term
power and transmission agreements through base rates as approved by the DPU. 

    Revenues collected through base rates are generally designed to reimburse
the Company for all costs of operation other than fuel, the energy portion of
purchased power, transmission and C&LM costs while providing a fair return on
capital invested in the business.  However, as a result of a DPU-mandated
recovery mechanism for the capacity-related costs described above, the Company
has experienced a revenue excess or shortfall when unit sales and/or the costs
recoverable in base rates vary from test-period levels.  This issue, which has
had a significant impact on the Company's net income, was addressed in a
settlement agreement approved by the DPU in May 1995 that permits deferral of
up to $2 million annually for these capacity-related purchased power costs.
There have been no deferrals to date.

        Customer Transition Charge

        In September 1995, the DPU issued a ruling largely approving four rate
tariffs, including a Customer Transition Charge (CTC), that were filed by the
Company on March 15, 1995.  The CTC will protect remaining customers from
paying certain costs, often referred to as stranded investment costs, that
were incurred in the event that the Company's largest customers discontinue
full service, yet still remain connected for back-up and other services. 
These costs include long-term power contracts entered into to meet projected
energy requirements, investments in substations, underground and overhead
lines and current and future decommissioning costs associated with nuclear
plants.  This ruling is believed to be the first retail stranded cost charge 
<PAGE>
<PAGE 8>

                       CAMBRIDGE ELECTRIC LIGHT COMPANY

approved nationally and follows the DPU restructuring order which endorsed, in
principle, the recovery of stranded investment costs.

    Through the CTC, the Company will initially recover 75% of net stranded
investment costs as calculated in its proposal.  The Company's other rates in-
clude a Supplemental Service Rate, a Standby Service Rate and a Maintenance
Service Rate each of which were approved with only minor changes.  The Company
is encouraged by the DPU's position on recovery of stranded investment costs
and expects to address recovery of the remaining 25% in its restructuring
filing.

    The Massachusetts Institute of Technology (MIT) appealed the DPU's deci-
sion to the Massachusetts Supreme Judicial Court (the SJC).  The Company is an
intervenor in this proceeding.  While no schedule is set for a decision from
the SJC, the Company anticipates a decision sometime in the second quarter of
1997.  At this time, the Company is unable to predict the outcome of this
proceeding.  In addition, on February 29, 1996, the FERC denied a petition
filed in January 1996 by MIT, which sought relief from paying the CTC, on the
premise that stranded costs are to be resolved at the state level.  The
Company believes that the FERC's action will be an important factor that the
SJC will consider in the appeal process.

    In a previous legal proceeding, on August 27, 1996, the United States
District Court for the District of Massachusetts (District Court) granted the
motions for summary judgement of the Company and the DPU and dismissed the May
1996 complaint filed by MIT.  In its complaint, MIT had alleged that the CTC
approved by the DPU and implemented by the Company violated the Public Utility
Regulatory Policies Act of 1978 (PURPA).  In dismissing MIT's complaint, the
District Court found that MIT's complaint involved an allegation relating to
the DPU's application of PURPA, which is not within the District Court's
jurisdiction.

    (c) Electric Industry Restructuring

    In August 1995, the DPU issued an order calling for the restructuring of
the electric utility industry in Massachusetts.  On May 1, 1996, the DPU
issued a second order containing proposed rules for implementing electric
industry restructuring that were the subject of public comment and hearings
during June and July 1996.  Subsequently, on December 30, 1996, the DPU issued
another order announcing its "Model Rules and Legislative Proposal" as a guide
in the creation of a competitive market for electric generation in
Massachusetts that would provide customers with the opportunity to achieve
lower electric bills beginning January 1, 1998.  The order also required
electric utilities to file by March 3, 1997, revenue-neutral, unbundled rates
and model bills showing a breakdown of the bill into generation, transmission,
distribution and access charge categories.

    In its "Model Rules," the DPU has proposed that the minimum structural
reorganization needed to create a competitive market is the functional
separation of generation, transmission and distribution within one integrated
company, and the establishment of a separate marketing affiliate if a company
retains generation assets.  The Massachusetts Legislature, which will render
the final passage of any restructuring law, is now considering the DPU's
proposed legislation.  In addition, on March 20, 1997, the Legislature's own
Joint Committee on Electric Utility Restructuring (the Committee) issued a 
<PAGE>
<PAGE 9>

                       CAMBRIDGE ELECTRIC LIGHT COMPANY

comprehensive policy report which outlines options for the Legislature's
consideration as debate on this issue continues.  In addition to the report,
the Committee formulated its own recommendations and corresponding legislative
package designed to address each of the major areas of the law which must
develop if electric utility restructuring is to be successfully implemented in
Massachusetts. 

    Other elements of the DPU's Model Rules provide that electric customers
will be able to buy their power on the open market; distribution services will
remain a monopoly service offered exclusively by the existing local distribu-
tion companies in clearly defined service territories; and customers will have
three types of electric generation choices.  First, customers may enter into
unregulated agreements with a competitive supplier for the provision of gener-
ation.  Second, customers may continue to buy power directly from their elec-
tric distribution company at a price regulated by the DPU.  Third, customers
who have received generation from a competitive supplier but who, for any
reason, have stopped receiving such generation will be able to receive default
generation service, provided by distribution companies at spot market price.

    Changes in the electric industry reflected in the DPU's proposal could
reduce the opportunity that currently exists for electric companies to recover
their investment in generating plant and other expenditures previously
approved by the DPU and included in current rates.  The potential losses,
which may result from subjecting electric company generation to the pressures
of a competitive market, are typically referred to as "stranded costs."  The
single largest component of stranded costs which are significant to the system
relates to above market purchased power contracts that the Company and
Commonwealth Electric have with non-utility generators.  However, the DPU has
concluded that it is in the public interest to provide electric companies a
reasonable opportunity to collect net, non-mitigable stranded costs.  The DPU
has proposed that stranded costs associated with owned generation facilities,
regulatory assets, and minimum purchased power obligations be collected over
the expected economic life of the generating facility, the current amortiza-
tion schedule of the regulatory asset, or the contractual term of the
purchased power obligation, respectively.  The DPU's proposal requires that
any stranded cost recovery for an electric utility be subject to mitigation
efforts to reduce embedded costs over time.  The Model Rules specify that
mitigation should include such measures as sales of capacity and energy from
owned generation, renegotiation or buy-out of purchased power contracts, and
sales and voluntary writedowns of assets.  Further, the DPU will conduct
stranded cost charge reconciliations at years two, five and ten following the
date of retail access.

    During the last several months, three Massachusetts electric utilities
have announced negotiated settlement agreements with the Massachusetts
Attorney General's Office (Attorney General) that include divestiture of
generating assets, provision for a ten percent reduction in customers' charges
and recovery of stranded costs through a non-bypassable access charge.  One
settlement agreement has already been approved by the DPU.  Implementation of
any restructuring settlement may be affected by actions of the Massachusetts
Legislature.

    The Company and Commonwealth Electric are engaged in preliminary settle-
ment discussions with the Attorney General, and expect to reach a comprehen-
sive settlement during the first half of 1997.  In the unlikely event that

                       CAMBRIDGE ELECTRIC LIGHT COMPANY

the parties are unable to complete a settlement, the companies would file a
full restructuring plan with the DPU.

    As described in Note 2(b) to the Notes to Financial Statements, the
Company complies with the provisions of Statement of Financial Accounting
Standards (SFAS) No. 71, "Accounting for the Effects of Certain Types of
Regulation."  In the event the Company determined that it no longer met the
criteria for following SFAS No. 71, the accounting impact would be an
extraordinary, non-cash charge to operations in an amount that could be
material.  Criteria that could give rise to the discontinuance of SFAS No. 71
include: 1) increasing competition restricting the Company's ability to
establish prices to recover specific costs, and 2) a significant change in the
current manner in which rates are set by regulators.  The Company periodically
reviews these criteria to ensure that the continuing application of SFAS No.
71 is appropriate.  Based on the current evaluation of the various factors and
conditions that are expected to impact future cost recovery, the Company
believes that its regulatory assets, including those related to generation,
are probable of future recovery.

    Competition

    The Company continues to develop and implement strategies that deal with
the increasingly competitive environment facing the electric business.  The
inherently high cost of providing energy services in the Northeast has placed
the region at a competitive disadvantage as more customers begin to explore
alternative energy supply options.  Pursuant to its aforementioned Model
Rules, the DPU is proposing to implement programs under which utility and non-
utility generators can sell electricity to customers of other utilities
without regard to previously closed franchise service areas.  In 1994, the DPU
began an inquiry into incentive ratemaking.

    Company actions in response to the new competitive challenges have been
well received by regulators, business groups and customers.  The Company has
developed and will continue to develop innovative pricing mechanisms designed
to retain existing customers, add new retail and wholesale customers and
expand beyond current markets.

    On February 6, 1997, due to the dramatically changing nature of the
electric and gas industries, the System announced the consolidation of
management personnel of Commonwealth Electric, Commonwealth Gas, COM/Energy
Services Company and the Company effective on that date.  COM/Electric and
COM/Gas will continue to operate under their existing company names.  The
consolidation process for these companies will involve the merging of similar
functions and activities to eliminate duplication in order to create the most
efficient and cost-effective operation possible and will ultimately result in
the elimination of approximately 300 (15% of system) positions system-wide.

    In March 1994, the Company was successful in negotiating a seven-year
service agreement with Harvard University, whose sales in 1996, 1995 and 1994
accounted for approximately 9.8%, 9.4% and 8.5%, respectively, of the
Company's total unit sales for those years.

    During 1996, a decrease in retail unit sales was virtually offset by an
increase in wholesale sales, resulting in a 0.1% increase in total sales.  The
lower retail unit sales reflects a decrease in industrial sales and a
significant decline in sales to Massachusetts Institute of Technology, a large
commercial customer that constructed its own cogeneration facility and has
elected to receive standby service only.  The increase in wholesale sales
reflects an increase in sales to NEPOOL due to changes in the Company's
capacity needs.

    For 1995, the Company's total unit sales decreased 9.3% and reflected a 
significant decrease in wholesale sales to NEPOOL.  Retail unit sales
increased slightly and reflected moderate increases in the commercial and
residential sectors.

Operating Revenues

    Operating revenues decreased approximately $3.2 million or 2.6% during
1996 due to a lower level of retail unit sales ($1.3 million), lower costs for
electricity purchased for resale ($742,000), transmission charges ($684,000)
and C&LM charges ($145,000), offset, in part by an increase in fuel costs.

    Operating revenues for 1995 declined $4.9 million (3.8%) due primarily to
decreases in wholesale unit sales, electricity purchased for resale ($3.2
million), C&LM charges ($764,000), transmission charges ($345,000), and fuel
costs ($125,000) offset, in part, by a small increase in retail unit sales. 
Also impacting the change was the implementation of a $1.5 million rate refund
pursuant to a May 1995 settlement agreement, approximately $1.3 million of
which was included in the decrease in electricity purchased for resale.

    As a result of a DPU-mandated recovery mechanism implemented in 1993 for
capacity-related costs associated with certain long-term purchased power

<PAGE 15>

                       CAMBRIDGE ELECTRIC LIGHT COMPANY

contracts, the Company has experienced a revenue excess or shortfall when unit
sales and/or the costs recoverable in base rates vary from test-period levels. 
This issue, which has had a significant impact on net income, was addressed in
a settlement agreement approved by the DPU in May 1995 (refer to the "Cost
Recovery" section in Item 1 of this report for additional details).  During
1996, 1995 and 1994, the Company overrecovered approximately $290,000,
$900,000 and $3.2 million, respectively, resulting in an increase to net
income of approximately $177,000, $545,000 and $2 million, respectively.

    The following is an analysis of revenue components for the years 1996,
1995 and 1994:

    (*) Includes sales for resale and other base rate revenue.

Electricity Purchased For Resale, Transmission and Fuel

    To satisfy demand requirements and provide required reserve capacity, the
Company purchases power on a long and short-term basis through entitlements
pursuant to power contracts with other New England and Canadian utilities,
Qualifying Facilities and other non-utility generators through a competitive
bidding process that is regulated by the DPU.  The Company supplements these
sources with its own generating capacity.

    Electricity purchased for resale, transmission and fuel costs decreased
approximately $900,000 (1.1%) in 1996 due primarily to a decline in purchases
from NEPOOL, lower costs for nuclear power and from affiliate Canal Electric
Company's (Canal) Unit 2 which was out of service for approximately five
months for scheduled maintenance and was returned to service in mid-August
1996.  The scheduled outage of Unit 2 also included the completion of a
fueling conversion enabling the Unit to burn natural gas and oil.  These
reductions were offset, in part, by an increase in power purchased from Canal
Unit 1 which was out of service from January until August 1995 due to a
combination of scheduled and unscheduled maintenance.

    During 1995, electricity purchased for resale, transmission and fuel costs
decreased $3.7 million or 4.5% due primarily to a $3.2 million reduction in
purchased power costs which reflects the decreased availability of Canal Unit
1 during 1995, as discussed above.  In addition, a nuclear unit remained out
of service for most of 1995 while undergoing extensive generator repairs.

<PAGE 16>

                       CAMBRIDGE ELECTRIC LIGHT COMPANY

Other Operation and Maintenance

    Other operation expense increased only 0.6% during 1996 as increases in
liability insurance ($793,000) and postretirement benefits costs ($304,000)
were offset, in part, by lower pension expense ($106,000), the absence of
legal fees ($293,000) associated with the cancellation of a power contract in
1995, lower fees for industry-related research and development ($186,000) and
lower C&LM costs ($145,000).  Maintenance costs decreased $340,000 due
primarily to a lower level of repairs at the Company's Kendall generating
unit.

    During 1995, other operation decreased $887,000 (4.1%) due primarily to a
decline in liability insurance ($856,000) due to adjustments to insurance
accruals that reflected better than anticipated experience, lower C&LM costs
($764,000) and a decline in the provision for bad debts reflecting improved
collection experience ($234,000).  This was offset, in part, by higher costs
for labor ($669,000) and postretirement benefits ($366,000).  Maintenance
costs increased $605,000 due primarily to repairs to the Company's Kendall and
Blackstone generating units.

Depreciation and Taxes

    Depreciation expense increased 3.1% and 2.4% in 1996 and 1995,
respectively, due to higher levels of depreciable property, plant and
equipment.  Federal and state income taxes decreased during 1995 by
approximately 17% due to a lower level of pretax income.

Other Income and Interest Charges

    The significant increase in other income during 1996 was due primarily to
the recognition of a gain relating to the sale of a parcel of land ($664,000)
and a higher rate of return relative to steam production for an affiliate
steam company ($346,000).  Interest charges decreased 22.2% during 1996 due
primarily to the repayment of a $20 million (9.97%) long-term debt issue
during the second quarter, the effect of which was partially offset by a
higher level of short-term bank borrowings.  The weighted average short-term
interest rate was 5.6% during 1996 as compared to 6.1% during 1995.

    Interest charges during 1995 increased 5% due to a higher level of short-
term borrowings and higher short-term interest rates (6.1% in 1995 versus 4.3%
in 1994) offset, somewhat, by an increase in the debt component of allowance
for funds used during construction (AFUDC) ($82,000).

Forward-Looking Statements

    This report contains statements which, to the extent they are not recita-
tions of historical fact, constitute "forward-looking statements" and are
intended to be subject to the safe harbor protection provided by the Private
Securities Litigation Reform Act of 1995.  A number of important factors
affecting the Company's business and financial results could cause actual
results to differ materially from those stated in the forward-looking state-
ments.  Those factors include developments in the legislative, regulatory and
competitive environment, certain environmental matters, demands for capital
expenditures and the availability of cash from various sources, and 
<PAGE>

                       CAMBRIDGE ELECTRIC LIGHT COMPANY

uncertainty as to regulatory approval of the full recovery of regulatory
assets and other stranded costs.

Environmental Matters

    The Company is subject to laws and regulations administered by federal,
state and local authorities relating to the quality of the environment.  These
laws and regulations affect, among other things, the siting and operation of
electric generating and transmission facilities and can require the installa-
tion of expensive air and water pollution control equipment.  These regula-
tions have had an impact on the Company's operations in the past and will
continue to have an impact on future operations, capital costs and construc-
tion schedules of major facilities.

    Effective January 1, 1997, the Company will adopt the provisions of
Statement of Position (SOP) 96-1, "Environmental Remediation Liabilities." 
This Statement provides authoritative guidance for recognition, measurement,
display and disclosure of environmental remediation liabilities in financial
statements.  Management does not believe that SOP 96-1 will have a material
adverse effect on the Company's results of operations or financial position.

Item 8. Financial Statements and Supplementary Data


                   REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS

To the Board of Directors of Cambridge Electric Light Company:

    We have audited the accompanying balance sheets of CAMBRIDGE ELECTRIC
LIGHT COMPANY (a Massachusetts corporation and wholly-owned subsidiary of
Commonwealth Energy System) as of December 31, 1996 and 1995, and the related
statements of income, retained earnings and cash flows for each of the three
years in the period ended December 31, 1996.  These financial statements and
schedules referred to below are the responsibility of the Company's
management.  Our responsibility is to express an opinion on these financial
statements and schedules based on our audits.

    We conducted our audits in accordance with generally accepted auditing
standards.  Those standards require that we plan and perform the audit to
obtain reasonable assurance about whether the financial statements are free of
material misstatement.  An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements.  An audit
also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation.  We believe that our audits provide a reasonable basis
for our opinion.

    In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of Cambridge Electric Light
Company as of December 31, 1996 and 1995, and the results of its operations
and its cash flows for each of the three years in the period ended
December 31, 1996, in conformity with generally accepted accounting
principles.

    Our audits were made for the purpose of forming an opinion on the basic
financial statements taken as a whole.  The schedules listed in the index to
financial statements and schedules are presented for purposes of complying

                       CAMBRIDGE ELECTRIC LIGHT COMPANY
                         NOTES TO FINANCIAL STATEMENTS

(1) General Information

    Cambridge Electric Light Company (the Company) is a wholly-owned
subsidiary of Commonwealth Energy System (the System).  The System is the
parent company and, together with its subsidiaries, is collectively referred
to as "the system."  The System is an exempt public utility holding company
under the provisions of the Public Utility Holding Company Act of 1935 with
investments in four operating public utility companies located in central,
eastern and southeastern Massachusetts and several non-regulated companies.

    The Company's operations are involved in the production and sale of elec-
tricity to approximately 44,500 customers in the city of Cambridge,
Massachusetts.  The service territory encompasses a seven square-mile area
with a population of approximately 96,000.  In addition, the Company sells
power for resale to the New England Power Pool (NEPOOL) and the Town of
Belmont, Massachusetts (Belmont), and sells steam from its electric generating
stations at wholesale to an affiliated company for distribution to customers
for space heating and other purposes.

    The Company has 151 regular employees, 112 (74%) of whom are represented
by a single collective bargaining unit with a contract that expires in 1998. 
Employee relations have generally been satisfactory.

(2) Significant Accounting Policies

    (a) Principles of Accounting

    The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period.  Actual results could differ from those estimates.

    Certain prior year amounts are reclassified from time to time to conform
with the presentation used in the current year's financial statements.

    (b) Regulatory Assets and Liabilities

    The Company is regulated as to rates, accounting and other matters by
various authorities including the Federal Energy Regulatory Commission (FERC)
and the Massachusetts Department of Public Utilities (DPU).

    Based on the current regulatory framework, the Company accounts for the
economic effects of regulation in accordance with the provisions of Statement
of Financial Accounting Standards (SFAS) No. 71, "Accounting for the Effects
of Certain Types of Regulation."  The Company has established various
regulatory assets in cases where the DPU and/or the FERC have permitted or are
expected to permit recovery of specific costs over time.  Similarly, the
regulatory liabilities established by the Company are required to be refunded
to customers over time.  Effective January 1, 1996, the Company adopted SFAS
No. 121, "Accounting for the Impairment of Long-Lived Assets and for Long-
Lived Assets to be Disposed Of."  SFAS No. 121 imposes stricter criteria for
regulatory assets by requiring that such assets be probable of future recovery
<PAGE>
<PAGE 26>

                       CAMBRIDGE ELECTRIC LIGHT COMPANY

at each balance sheet date.  SFAS No. 121 did not have an impact on the
Company's financial position upon adoption.  This result may change as
modifications are made to the current regulatory framework due to ongoing
electric industry restructuring efforts in Massachusetts.  If all or a
separable portion of the Company's operations becomes no longer subject to the
provisions of SFAS No. 71, a write-off of related regulatory assets and
liabilities would be required, unless some form of transition cost recovery
continues through rates established and collected for the Company's remaining
regulated operations.  In addition, the Company would be required to determine
any impairment to the carrying costs of deregulated plant and inventory
assets.  However, on December 30, 1996, the DPU issued an order containing
"Model Rules" for industry restructuring that management believes would
essentially allow full recovery of stranded costs.  For additional information
relating to industry restructuring, see the "Electric Industry Restructuring"
section under Management's Discussion and Analysis of Results of Operations.

    The principal regulatory assets included in deferred charges at
December 31, 1996 and 1995 were as follows:

                                                       1996         1995

    The regulatory liabilities, reflected in the accompanying Balance Sheets
and related to deferred income taxes, were $3.2 million at December 31, 1996
and 1995.

    As of December 31, 1996, $40.7 million of the Company's regulatory assets
and all of its regulatory liabilities are reflected in rates charged to
customers over a weighted average period of approximately 11 years.

    (c) Transactions with Affiliates

    Transactions between the Company and other system companies include
purchases and sales of electricity, including purchases from Canal Electric
Company (Canal), an affiliate wholesale electric generating company.  Other
Canal transactions include costs relating to the abandonment of Seabrook 2 and
the recovery of a portion of Seabrook 1 pre-commercial operation costs.  In
addition, payments for management, accounting, data processing and other
services are made to an affiliate, COM/Energy Services Company.  Transactions
with other system companies are subject to review by the DPU.

    The Company's operating expenses include the following major intercompany
transactions for the periods indicated:

       1995             10 148             6 973                1 465
       1994             11 650             8 622                9 780

    The costs for the Canal and Seabrook 1 units are included in the long-term
obligation table listed in Note 3(b).  In addition, the Company purchased
natural gas from an affiliate, Commonwealth Gas Company, totaling $621,000,
$1,969,000 and $2,158,000 in 1996, 1995 and 1994, respectively.

    (d) Operating Revenues

    Customers are billed for their use of electricity on a cycle basis
throughout the month.  To reflect revenues in the proper period, the estimated
amount of unbilled sales revenue is recorded each month.

    The Company is generally permitted to bill customers currently for costs
associated with purchased power and transmission, fuel used in electric
production and conservation and load management (C&LM) costs through adjust-
ment clauses.  Amounts recoverable under the adjustment clauses are subject to
review and adjustment by the DPU.  The amount of such costs incurred by the
Company but not yet reflected in customers' bills is recorded as unbilled
revenues.  

    (e) Depreciation

    Depreciation is provided using the straight-line method at rates intended
to amortize the original cost and the estimated cost of removal less salvage
of properties over their estimated economic lives.  The average composite
depreciation rate was 2.69% in 1996, 2.72% in 1995 and 2.76% in 1994.

    (f) Maintenance

    Expenditures for repairs of property and replacement and renewal of items
determined to be less than units of property are charged to maintenance
expense.  Additions, replacements and renewals of property considered to be
units of property are charged to the appropriate plant accounts.  Upon
retirement, accumulated depreciation is charged with the original cost of
property units and the cost of removal less salvage.

    (g) Allowance for Funds Used During Construction

    Under applicable rate-making practices, the Company is permitted to
include an allowance for funds used during construction (AFUDC) as an element
of its depreciable property costs.  This allowance is based on the amount of
construction work in progress that is not included in the rate base on which
the Company earns a return.  An amount equal to the AFUDC capitalized in the
current period is reflected in the accompanying Statements of Income.
<PAGE>
<PAGE 28>

                       CAMBRIDGE ELECTRIC LIGHT COMPANY

    While AFUDC does not provide funds currently, these amounts are recover-
able in revenues over the service life of the constructed property.  The
amount of AFUDC recorded was at a weighted average rate of 6.25% in 1996,
7.75% in 1995 and 6.5% in 1994.

(3) Commitments and Contingencies

    (a) Financing and Construction Programs

    The Company is engaged in a continuous construction program presently
estimated at $27 million for the five-year period 1997 through 2001.  Of that
amount, $5.9 million is estimated for 1997.  The program is subject to
periodic review and revision because of factors such as changes in business
conditions, rates of customer growth, effects of inflation, maintenance of
reliable and safe service, equipment delivery schedules, licensing delays,
availability and cost of capital and environmental factors.  The Company
expects to finance these expenditures on an interim basis with internally
generated funds and short-term borrowings which are ultimately expected to be
repaid with the proceeds from sales of long-term debt and equity securities.

    (b) Power Contracts

    The Company has long-term contracts for the purchase of electricity from
various sources.  Generally, these contracts are for fixed periods and require
payment of a demand charge for the capacity entitlement and an energy charge
to cover the cost of fuel.  Pertinent information with respect to life-of-the-
unit contracts for power from nuclear units in which the Company has an equity
ownership (Yankee Nuclear Units) is as follows:

    The Company pays its share of decommissioning expense to each of the
operators of these nuclear facilities as a cost of electricity purchased for
resale.

    The Company also has long-term contracts to purchase capacity from other
generating facilities.  Information relative to these contracts is as follows:

        capacity entitlements of 4.99% and 9.97%.

    Costs pursuant to these contracts are included in electricity purchased
for resale in the accompanying Statements of Income and are recoverable in
revenue.

    The estimated aggregate obligations under the life-of-the-unit contracts
for capacity from the operating Yankee Nuclear Units and other long-term
purchased power obligations, including the Canal and Seabrook 1 units, in
effect for the five years subsequent to 1996 are as follows:

            1998              11 003          40 318         51 321
            1999              12 768          42 215         54 983

    In addition, the Company incurred costs for purchases from the New England
Power Pool of $10,973,000, $14,185,000 and $6,241,000 in 1996, 1995 and 1994,
respectively.

    (c) Price-Anderson Act

    Under the Price-Anderson Act (the Act), owners of nuclear power plants
have the benefit of approximately $8.9 billion of public liability coverage
that would compensate the public for valid bodily injury and property loss on
a no fault basis in the event of an accident at a commercial nuclear power
plant.  Under the provisions of the Act, each nuclear reactor with an
operating license can be assessed up to $79.3 million per nuclear incident
with a maximum assessment of $10 million per incident within one calendar
year.  Nuclear plant owners have initiated insurance programs designed to help
cover liability claims relating to property damage, decontamination,
replacement power and business interruption costs for participating utilities
arising from a nuclear incident.

    The Company has an equity ownership interest in four nuclear generating
facilities.  The operators of these units maintain nuclear insurance coverage
(on behalf of the owners of the facilities) with Nuclear Electric Insurance 
<PAGE>
<PAGE 30>

                       CAMBRIDGE ELECTRIC LIGHT COMPANY

Limited (NEIL II) and the combined American Nuclear Insurers/Mutual Atomic
Energy Liability Underwriters (ANI).  NEIL II provides $2.25 billion of
property, boiler, machinery and decontamination insurance coverage, including
accidental premature decommissioning insurance in the amount of the shortfall
in the Decommissioning Trust Fund, in excess of the underlying $500 million
policy.  All companies insured with NEIL are subject to retroactive
assessments if losses exceed the accumulated funds available.  ANI provides
$500 million of "all risk" property damage, boiler, machinery and
decontamination insurance.  An additional $200 million of primary financial
protection coverage is provided for off-site bodily injury or property damage
caused by a nuclear incident.  ANI also provides secondary financial
protection liability insurance which currently provides $8.7 billion of
retrospective insurance premium benefits in accordance with the provisions of
the Act.  Additional coverage ($200 million) provided by ANI includes tort
liability protection arising out of radiation injury claims by nuclear workers
and injury or property damage caused by the transportation or shipment of
nuclear materials or waste.

    Based on its various ownership interests in the four nuclear generating
facilities, the Company's retrospective premium could be as high as $1.3
million yearly or a cumulative total of $12.3 million, exclusive of the effect
of inflation indexing (at five-year intervals) and a 5% surcharge ($4 million)
in the event that total public liability claims from a nuclear incident exceed
the funds available to pay such claims.

    (d) Guarantee Agreement

    In connection with its investment in Maine Yankee Atomic Power Company,
the Company has guaranteed its pro-rata portion of that company's nuclear fuel
financing.  At December 31, 1996, the Company's portion amounted to $800,000.

    (e) Yankee Nuclear Power Plants

    On July 22, 1996, Connecticut Yankee Atomic Power Company (Connecticut
Yankee), which operates the Connecticut Yankee nuclear power plant (the
Connecticut plant), took the unit out of service in connection with certain
safety-related issues and refueling.  During the outage, Connecticut Yankee's
owners evaluated the economics of continuing to operate the plant over the
remaining ten years of its current license life, compared to the costs of
closing the plant and incurring replacement power for the same period.  As a
result of this evaluation, on December 4, 1996, Connecticut Yankee's Board of
Directors voted to permanently shut down the plant.

    The Company has an equity ownership interest in Connecticut Yankee of 4.5%
which, at December 31, 1996, amounted to approximately $4.7 million.  The
Company, through its ownership interest, has a corresponding capacity
entitlement and power purchase obligation.

    The preliminary estimate of the sum of future payments for the closing,
decommissioning and recovery of the remaining investment in the plant is
approximately $797 million.  The Company's share of these remaining estimated
costs is approximately $36 million.  Based upon regulatory precedent,
Connecticut Yankee believes that it would continue to collect from its power
purchasers (including the Company) its decommissioning costs, unrecovered
plant investment and other costs associated with the permanent closure of the
plant over the remaining period of the plant's operating license that expires
in 2007.  The Company does not believe the ultimate outcome of the early
closing of this plant will have a material adverse effect on its operations 
<PAGE>
<PAGE 31>

                       CAMBRIDGE ELECTRIC LIGHT COMPANY

and believes that recovery of these FERC-approved costs will continue to be
allowed in its rates at the retail level.

    This action follows the permanent shutdown of the Yankee Atomic plant in
Rowe, Massachusetts in 1992.  Due to changing conditions within the nuclear
industry, it is possible that the remaining two operating nuclear plants in
which the Company has an equity ownership interest could be shut down sometime
in the future prior to the expiration of each unit's operating license.

    (f) Environmental Matters

    The Company is subject to laws and regulations administered by federal,
state and local authorities relating to the quality of the environment.  These
laws and regulations affect, among other things, the siting and operation of
electric generating and transmission facilities and can require the
installation of expensive air and water pollution control equipment.  These
regulations have had an impact on the Company's operations in the past and
could have an impact on future operations, capital costs and construction
schedules of major facilities.

(4) Income Taxes

    For financial reporting purposes, the Company provides federal and state
income taxes on a separate-return basis.  However, for federal income tax
purposes, the Company's taxable income and deductions are included in the
consolidated income tax return of the System and it makes tax payments or
receives refunds on the basis of its tax attributes in the tax return in
accordance with applicable regulations.

    The following is a summary of the Company's provisions for income taxes
for the years ended December 31, 1996, 1995 and 1994:

                                            1996       1995       1994

    Deferred tax liabilities and assets are determined based on the difference
between the financial statement and tax bases of assets and liabilities using
enacted tax rates in effect in the year in which the differences are expected
to reverse.

    Accumulated deferred income taxes, net $13 951       $14 531

    The net year-end deferred income tax liability above is net of a current
deferred tax asset of $404,000 in 1996 which is included in other deferred
charges in the accompanying Balance Sheets and includes a current deferred tax
liability of $649,000 in 1995, included in accrued income taxes in the
accompanying Balance Sheets.

    The total income tax provision set forth previously represents 34% in
1996, 33% in 1995 and 34% in 1994 of income before such taxes.  The following
table reconciles the statutory federal income tax rate to these percentages:

(5) Employee Benefit Plans

    (a) Pension

    The Company has a noncontributory pension plan covering substantially all
regular employees who have attained the age of 21 and have completed one year
of service.  Pension benefits are based on an employee's years of service and
compensation.  The Company makes monthly contributions to the plan consistent
with the funding requirements of the Employee Retirement Income Security Act
of 1974.

    Components of pension expense and related assumptions to develop pension
expense were as follows:

    Pension expense reflects the use of the projected unit credit method which
is also the actuarial cost method used in determining future funding of the
plan.  The Company, in accordance with current ratemaking, is deferring the
difference between pension contribution, which is reflected in base rates, and
pension expense.  The funded status of the Company's pension plan (using a
measurement date of December 31) is as follows:

                                                   1996           1995

    Plan assets consist primarily of fixed-income and equity securities.
Fluctuations in the fair market value of plan assets will affect pension
expense in future years.

    (b) Other Postretirement Benefits

    Certain employees are eligible for postretirement benefits if they meet
specific requirements.  These benefits could include health and life insurance
coverage and reimbursement of Medicare Part B premiums.  Under certain
circumstances, eligible employees are required to make contributions for
postretirement benefits.

    To fund its postretirement benefits, the Company makes contributions to
various voluntary employees' beneficiary association (VEBA) trusts that were
established pursuant to section 501(c)(9) of the Internal Revenue Code (the
Code).  The Company also makes contributions to a subaccount of its pension
plan pursuant to section 401(h) of the Code to fund a portion of its
postretirement benefit obligation.  The Company contributed approximately $1.2
million, $1.3 million and $1.4 million to these trusts during 1996, 1995 and
1994, respectively.

    The net periodic postretirement benefit cost for the years ended
December 31, 1996, 1995 and 1994 include the following components and related
assumptions:

                                               1996      1995      1994

    The following actuarial assumptions were used in determining the plan's
estimated accumulated postretirement benefit obligation (APBO) and funded
status for 1996 and 1995:
                                                      1996        1995

    Discount rate                                     7.50%       7.25%
    Rate of increase in future compensation           4.25        4.25
    Medicare Part B premiums                          9.50       12.20
    Medical care                                      7.00        8.00
    Dental care                                       5.00        5.00

    The above dental rate remains constant through the year 2007.  Rates for
Medicare Part B premiums and medical care decrease to 3.1% and 5%,
respectively, by 2007 and remain at that level thereafter.  A one percent
change in the medical trend rate would have a $150,000 impact on the Company's
annual expense and would change the APBO by approximately $1.4 million.

    Plan assets consist primarily of fixed-income and equity securities.
Fluctuations in the fair market value of plan assets will affect postretire-
ment benefits expense in future years.

    Effective with its June 1, 1993 rate order from the DPU, the Company was
allowed to recover its SFAS No. 106 expense in base rates over a four-year
phase-in period with carrying costs on the deferred balance.  At December 31,
1996 and 1995, the Company's deferral amounted to approximately $2.1 million
and $2.2 million, respectively.

    (c) Savings Plan

    The Company has an Employees Savings Plan that provides for Company
contributions equal to contributions by eligible employees of up to four
percent of each employee's compensation rate and up to five percent for those
employees no longer eligible for postretirement health benefits.  The
Company's contribution was $310,000 in 1996, $317,000 in 1995 and $325,000 in
1994.

(6) Interim Financing and Long-Term Debt

    (a) Notes Payable to Banks

    The Company and other system companies maintain both committed and
uncommitted lines of credit for the short-term financing of their construction
programs and other corporate purposes.  As of December 31, 1996, system
companies had $135 million of committed lines of credit that will expire at
varying intervals in 1997.  These lines are normally renewed upon expiration
and require annual fees of up to .1875% of the individual line.  At December
31, 1996, the system's uncommitted lines of credit totaled $20 million. 
Interest rates on the Company's outstanding borrowings generally are at an
adjusted money market rate and averaged 5.6% and 6.1% in 1996 and 1995,
respectively.  Notes payable to banks totaled $18,725,000 and $2,675,000 at
December 31, 1996 and 1995, respectively.

    (b) Advances from Affiliates

     Notes payable to the System totaled $4,665,000 and $2,425,000 at December
31, 1996 and 1995, respectively.  These notes are written for a term of up to
11 months and 29 days.  Interest is at the prime rate and is adjusted for
changes in that rate during the term of the notes.  The rate averaged 8.3% and
8.8% in 1996 and 1995, respectively.

    The Company is a member of the COM/Energy Money Pool (the Pool), an
arrangement among the subsidiaries of the System, whereby short-term cash
surpluses are used to help meet the short-term borrowing needs of the utility
subsidiaries.  In general, lenders to the Pool receive a higher rate of return
than they otherwise would on such investments, while borrowers pay a lower
interest rate than those available from banks.  Interest rates on the out-
standing borrowings are based on the monthly average rate the Company would
otherwise have to pay banks, less one-half the difference between that rate
and the monthly average U.S. Treasury Bill weekly auction rate.  The borrow-
ings are for a period of less than one year and are payable upon demand. 
Rates on these borrowings averaged 5.3% and 5.8% in 1996 and 1995, respective-
ly.  Notes payable to the Pool totaled $400,000 at December 31, 1996.  The
Company had no notes payable to the Pool at December 31, 1995.

    (c) Long-Term Debt Maturities and Retirements

    Long-term debt outstanding, exclusive of current maturities, current
sinking fund requirements and related premiums, is as follows:

                                              Original  Balance December 31,

    The carrying amount of cash, notes payable to banks and advances to/from
affiliates approximates the fair value because of the short maturity of these
financial instruments.

    The estimated fair value of long-term debt is based on quoted market
prices of the same or similar issues or on the current rates offered for debt
with the same remaining maturity.  The fair values shown above do not purport
to represent the amounts at which those obligations would be settled.

(7) Dividend Restriction

    At December 31, 1996 none of retained earnings was restricted against the
payment of cash dividends by terms of term loans and note agreements securing
long-term debt.  As of the same date, retained earnings also included
approximately $4,406,000 representing the Company's equity in undistributed
earnings of the nuclear companies.

(8) Lease Obligations

    The Company leases equipment and office space under arrangements that are
classified as operating leases.  These lease agreements are for terms of one
year or longer.  Leases currently in effect contain no provisions that
prohibit the Company from entering into future lease agreements or obliga-
tions.
